technical field

The invention relates to the technical field of connector production, in particular to a double-pin terminal insertion device and a terminal embedding device.

Background technique

With the development of the electronics industry, more and more electrical connectors are used, and there are more and more types. The electrical connector includes a housing and terminals, the housing is injection-molded, and the terminals are inserted into the housing. In general, the shape of the terminals is often sheet-like, and the surfaces are all flat. However, according to the actual design requirements of the product, the surface of some terminals may be slightly bent, which will cause such slightly bent terminals to not be well inserted into the housing.

In the past, the terminal was manually held and inserted into the slot on the housing, so the operation efficiency was extremely slow, and after a large number of repeated work, the workers often could not align the slot on the housing, which resulted in the need to insert a few more times. The terminal can be inserted into the housing only once, at this time, it is easy to cause problems such as bending of the pins on the terminal.

In use, the material conveying device 500 can sequentially convey the housings one by one along the first pre-insertion assembly 200 , the terminal insertion assembly 300 and the first riveting assembly 400 . The housing is pre-inserted and positioned on the first pre-insertion component 200 to determine whether the terminal slot is not slotted, so as to avoid the terminal directly colliding with the housing during subsequent insertion, resulting in waste of terminals. After the pre-insertion positioning is completed, the housing comes to the side of the terminal insertion assembly 300, and the terminals are inserted into the terminal sockets. Finally, the casing brings the terminal to the side of the first riveting assembly 400, and the first riveting assembly 400 rives the terminal, so that the terminal and the casing are tightly connected, and the connection stability between the terminal and the casing is improved. Prevent subsequent terminals from falling out of the terminal sockets.

The double-pin terminal insertion device cooperates with each other through the shell fixing assembly 100, the first pre-insertion assembly 200, the terminal insertion assembly 300 and the first riveting assembly 400, so as to realize the automatic insertion of the double-pin terminal with bending into the shell. , which can effectively improve the insertion efficiency of the double-pin terminal with curvature, and can accurately insert the terminal on the housing, further improve the product yield and ensure product quality.

As shown in FIGS. 1 to 4 , in an embodiment, the first pre-insertion assembly 200 includes a first support base 230 , a first cylinder 240 , a first moving member 250 , a first pre-insertion cylinder 260 , and a first guide base 270 and the first pre-insertion block 220;

The first support seat 230 is disposed on one side of the housing fixing assembly 100 , the first cylinder 240 is disposed on the first support seat 230 along the second preset direction, and the cylinder shaft of the first air cylinder 240 is connected with the first moving member 250 so that the The first moving member 250 is movably arranged on the first support base 230 along the second predetermined direction, and the first pre-insertion cylinder 260 and the first guide seat 270 are arranged on the first moving member 250 along the second predetermined direction , the first guide block 210 is fixed on the end of the first guide seat 270 facing the housing fixing assembly 100, the first pre-insertion block 220 is movably arranged on the first guide seat 270, the cylinder shaft of the first pre-insertion cylinder 260 is connected to the first The pre-insertion block 220 is connected for driving the first pre-insertion block 220 to move along the second preset direction.

In this way, the first guide groove on the first guide block 210 is at the same position as the terminal slot corresponding to the housing, so that the first pre-insertion block 220 can be accurately inserted into the terminal slot corresponding to the housing, and can quickly Perform the pre-insertion positioning operation. In addition, the first pre-insertion assembly 200 can also identify in advance whether the position of the terminal slot on the casing is in the wrong position. Since the terminal is small and thin, in order to achieve precise insertion, each casing needs to be inserted in the wrong position. The position of the terminal slot is kept in the correct position, and the first pre-insertion component 200 can play the role of judging and identifying the terminal slot in advance, which is beneficial to subsequent processing operations.

As shown in FIGS. 1 to 4 and 12 , in one embodiment, a square connecting block 221 is provided at one end of the first pre-insertion block 220 close to the first pre-insertion cylinder 260 . A first spring 222 is arranged therebetween.

When in use, the first pre-insertion cylinder 260 drives the first pre-insertion block 220 to move toward the housing. At this time, under the spring force of the first spring 222, the first pre-insertion block 220 is inserted into the terminal slot. The first spring 222 is not fully compressed; when the first pre-insertion block 220 has been inserted into the terminal slot of the housing, the cylinder shaft of the first pre-insertion cylinder 260 continues to extend toward the housing, thereby causing the first spring 222 When the compression starts, the first pre-insertion block 220 continues to provide a force to the terminal socket under the action of the spring force. Since the housing is formed by the injection molding process, it is inevitable that there will be residual plastic blocks at the terminal slots of the housing. These plastic blocks or plastic particles, these obstructions may affect the insertion of the terminal, or cause the surface of the terminal to be damaged. There are scratches. In this way, the insertion of the first pre-insertion block 220 can effectively remove these obstructions. If the first pre-insertion block 220 is blocked by these obstructions when entering, after the first spring 222 is compressed, the first pre-insertion block 220 is provided with a The elastic force can effectively enhance the force of the first pre-insertion block 220 on the terminal slot, so that the subsequent terminal insertion can be more smoothly. In this way, the arrangement of the first spring 222 can improve the success rate of terminal insertion, thereby effectively ensuring product quality.

Specifically, one end of the terminal slot of the housing has a protruding structure. In order to better fit the housing during the pre-insertion operation, the first guide block 210 has a narrow portion 212 and a wide portion 213, so as to better fit the housing. On the other hand, it can also fit with one end of the pre-insertion piece 223 corresponding to the wide portion 213 . In this way, the cooperation between the pre-insertion piece 223 and the first guide block 210 can be strengthened, so that the pre-insertion piece 223 can be accurately inserted into the terminal slot of the housing.

As shown in FIGS. 5-8 and 12 , in one embodiment, the terminal insertion assembly 300 includes a second support base 310 , a feeding mechanism 320 and an insertion mechanism 330 ;

The second support seat 310 is disposed on one side of the first pre-insertion component 200;

The feeding mechanism 320 includes a feeding rail 321, a speed regulating cylinder 322, a first hinge block 323, a first connecting rod 324, a second hinge block 325 and a deceleration block 326. The feeding rail 321 is arranged along the first preset direction on the On the second support base 310, the speed regulating cylinder 322 and the second hinge block 325 are arranged on one side of the feeding track 321, the cylinder shaft of the speed regulating cylinder 322 is connected with a first hinge block 323, and the first hinge block 323 is connected with the first One end of the connecting rod 324 is hinged, the second hinge block 325 is hinged with the other end of the first connecting rod 324, one end of the first connecting rod 324 close to the feeding track 321 protrudes to form a touch block 3241, and the deceleration block 326 is movably arranged on the feeding track 321 is in contact with the upper surface of the tape of the double-pin terminal, and the touch block 3241 is in contact with the deceleration block 326;

The inserting mechanism 330 is arranged on one side of the feeding mechanism 320 .

Specifically, a positioning mechanism 340 is further provided on the insertion mechanism 330 . The positioning mechanism 340 includes a positioning cylinder 341 , a positioning block 342 and a positioning needle 343 . In this way, the terminal can be effectively positioned and kept in a horizontal state for direct insertion into the housing. Since a horizontal pin of the dual-pin terminal needs to be inserted into the housing and extended from the housing, the horizontal pin of the dual-pin terminal has a certain length, so the center of gravity of the dual-pin terminal is deviated from the horizontal pin. If there is no positioning mechanism 340 , the double-pin terminal cannot maintain a horizontal device, and it cannot be smoothly inserted into the housing. Therefore, the end face of the positioning block 342 facing the double-pin terminal is set to be flat, and the purpose is to contact the material strip section of the double-pin terminal, so as to ensure that the double-pin terminal is kept in a horizontal state before insertion. In addition, for smooth insertion, the insertion part of the two-pin terminal needs to be set in the air.

In addition, the end surface of the deceleration block 326 facing the double-pin terminal is not a complete plane, but is composed of two planes with different slopes, and the plane close to the insertion platform has a larger slope. When the terminal passes through the deceleration block 326 , the speed regulating cylinder 322 controls the touch block 3241 of the first connecting rod 324 to contact the deceleration block 326 , so that the touch block 3241 provides a pressure to the deceleration block 326 , thereby increasing the deceleration block 326 Frictional force with the tape segment of the dual-pin terminal, thereby slowing the feed rate of the dual-pin terminal.

Further, because the positioning pins on the positioning mechanism 340 need to be inserted into the jacks of the material strip section of the double-pin terminal. During the terminal loading process, the positioning pins cannot be directly inserted. In addition, when the terminal transitions from the deceleration block 326 to the insertion mechanism 330, the terminal part begins to volley. If the terminal feeding speed is too fast at this time, it is easy to cause the positioning pin to be unable to align with the tape section of the double-pin terminal, resulting in positioning failure and affecting the insertion. In this way, the cooperating among the deceleration block 326 , the positioning mechanism 340 and the insertion mechanism 330 can complete the positioning of the terminal and ensure that the terminal can be inserted smoothly.

When in use, the feeding mechanism 320 controls the feeding of the double-pin terminal, and feeds the material to the insertion mechanism 330, the positioning mechanism 340 quickly positions the double-pin terminal, and the insertion mechanism 330 inserts the terminal into the housing to fix it on the housing of the assembly 100 .

As shown in FIGS. 5-8 and 12 , in one embodiment, a blanking port is provided on the feeding rail 321 , a first cutting block 3211 is provided at one end of the blanking port, and a second support seat 310 is provided A cutting cylinder 351 is provided, and the cylinder shaft of the cutting cylinder 351 is indirectly connected with the second cutting block 352 . In use, the first cutting block 3211 cooperates with the second cutting block 352 to cut the protection pins on the double-pin terminal, and then the cut protection pins pass through the blanking port for blanking. In addition, under the deceleration of the deceleration block 326, it is beneficial to slow down the feeding speed of the double-pin terminal, so that there is enough time for the second cutting block 352 to be cut and matched with the first cutting block 3211.

As shown in FIGS. 5-8 and 12 , in one embodiment, the insertion mechanism 330 includes an insertion cylinder 331 , a second moving member 332 , an insertion platform 333 , a stop cylinder 334 , a matching slider 335 and a stopper block336;

The cartridge cylinder 331 is arranged on one side of the feeding track 321 along the second preset direction, and the cylinder shaft of the cartridge cylinder 331 is connected with the second moving member 332 for driving the second moving member 332 along the second preset direction Moving, the inserting platform 333 is fixed on one end of the second moving member 332 close to the housing fixing assembly 100 , the stopper cylinder 334 is arranged on the second support base 310 along the second preset direction, and the cylinder shaft of the stopper cylinder 334 is matched with the The sliding block 335 is connected for driving the matching sliding block 335 to move along the second preset direction, and the bottom of the stop block 336 is movably connected with the matching sliding block 335 for driving the blocking block 336 to pass through the second support seat 310 along the move in the third preset direction;

Wherein, when the double-pin terminal is loaded onto the insertion platform 333 , the top of the stop block 336 is in abutment with the insertion platform 333 .

In use, the stopper cylinder drives the matching slide block 335 to move along the second preset direction, so as to lift the stopper block 336 and make the stopper block 336 abut against the insertion platform 333 . In this way, the advancement of the insertion platform 333 can be blocked, so that the terminals can be smoothly fed onto the insertion platform 333 . In addition, when the stop block 336 abuts against the insertion platform 333 , it also provides a supporting force to the insertion platform 333 to support the insertion platform 333 and balance the pressure of the positioning mechanism 340 on the insertion platform 333 .

Specifically, when the stopper block 336 abuts against the insertion platform 333 , the stopper block 336 is placed in the stopper support cavity, and at this time, the first inclined surface and the second inclined surface 3361 abut each other. In this way, the stopper block 336 and the insertion platform 333 have a simple structure, and can be closely matched with each other, which can increase the friction force between the first inclined surface and the second inclined surface 3361 , thereby raising the stopper block 336 and the insertion platform 333 connection stability and reliability.

When the stopper cylinder pushes the engaging slider 335 , the engaging slider 335 is slidably engaged with the first pulley 337 on the stopper block 336 , thereby realizing the lifting and lowering of the first pulley 337 .
