The invention relates to a screwing and fitting device
For fastening and loosening printed circuit boards for printed circuits on an electroplating frame by screwing in and unscrewing screws that are attached to both sides of a central spar in the same plane.

Devices of this type are not previously known. So far, such circuit boards were each by hand on electroplating racks
attached or loosened by screwing in and unscrewing toggle screws. This is not only particularly complex, but
also naturally leads to a different pressure for printed circuit boards.

The object of the invention is to create devices which allow the fastening and loosening of circuit boards on electroplating racks
Carry out automatically with a defined pressure.

According to the invention, this is achieved by means of a device of the type indicated at the beginning, which is characterized in that ... that rotary drives (l) for screwing in and unscrewing the screws (9)
are provided.

Advantageous embodiments of the invention continue to exist
in this,

a) that the rotary drives (l) represent independently working units,

is operated by a pneumatic cylinder. Due to the separation of the drives, it is optimally possible to to open and close the individual units with the same air pressure within an appropriate framework, regardless of time.

The same air pressure advantageously has the same effect Torque for all toggle screws of the electroplating frame. This torque is preferably provided via a pressure regulating valve Manometer adjustable and gives the corresponding holding force at Plague screws of the circuit boards to be electroplated.

The rotary actuators are each provided with a coupling piece. This sits on the splined shaft, is movable in the axial direction and is pushed up against the T-bolts of the by a spring Electroplating racks pressed.

During the rotation, the screw then latches in the coupling piece and rotates with, bis (reached the rack in the respective end position, and the movement is men thus come to a standstill, or) resulting from the clamping of the printed circuit board resistance higher than that of Pneumatic cylinder generated force has become.

All coupling pieces can pneumatically via an engagement plate Cylinders can be pulled down to bring the rack to the left or right basic position, even with the electroplating frame inserted to be able to slide without the toggle screws engaging

Figure 3 is a detailed plan view of the device FIG. 4 shows an electroplating frame with screws attached on both sides of a central spar in the same plane.

_; The mode of operation of the device can be seen from FIG. The screws (9) on the electroplating frame (15) used to clamp the circuit boards (16) engage in the coupling piece (7) of the rotary drive (1) when the frame (15) is inserted into the device.

The coupling pieces (7) can be moved axially on the splined shaft (8) » The splined shaft (8) is connected via the sleeve (17) to the axle (4), which at its lower end is not the one in this figure visible pinion (3) carries. This pinion engages in the rack (2), which is connected to the piston rod (19) of the Pneiimatikzylinders (5) is connected. That for tightening the screws (9) The required torque can be changed via the pressure of the compressed air supplied to the pneumatic cylinder (5). For this the regulating device (6) is used.

So that the circuit boards (16) at the correct height in the

^v * Clamping openings (3 * 0 of the electroplating frame can be inserted, are arranged on the work table (20) of the device support rods (21), which are adjustable in height. These support rods (21) also accommodate the inductive switches ( lk) whose signals are evaluated for the automatic control of the device.

To insert the frame (15) in the exact position in the device and to be able to fix, the coupling pieces (7) must first have moved downwards. This is done with the help of the indentation plate (11), which is also operated pneumatically.

If the frame (15) is inserted, the indentation plate ("H) is after moved up and the coupling pieces under spring pressure (7) engage in the toggle screws (9) of the electroplating frame.

The spring (10) used to generate the spring pressure on the coupling pieces (7) can be seen from FIG. This illustration also shows the position of the pinion (3) which engages in the rack (2). The mounting block (12) is used to fix the electroplating frame (15) in the correct position. The pneumatic cylinder (23) is connected to the engagement plate (11) and pulls this - and thus the coupling pieces (7) - downwards when actuated.

In Figure 3 , the device is shown in a plan view in detail. The indicated electroplating frame (15) is inserted into the device. It is fixed at the side by the bracket (24) and held down by the safety slide (I3). The slide (13) is shown once in the extended (25) and once in the retracted (26) position. It is also supported by § -10-

moves a pneumatic cylinder. It can be seen from the figure that each rotary drive (l) is assigned an inductive switch ( lk) which registers whether a circuit board is at this point and has to be attached or detached. This makes it possible to only activate the rotary actuators (l) required in each case.

Figure 4 shows a complete electroplating frame (15) »consisting of the frame head (27), the support rod (28), the cams (29) with the clamping openings (3 * 0 and the screws (9)). 31) and the pressure screw (32), the frame (15) can be clamped to the rail (33). Suspended on the rail (33), the frame (15) or several copies are transported through the treatment stations of the electroplating system at the same time Side view it can be seen that the actuating toggles of the screws (9) are all in one plane.
