Please refer to FIG. 4 for reference. The present invention is an automatic guidance education method for array probe modules, and the steps include: please refer to FIG. 1 and FIG. 2 together. Step S1, positioning and waiting Measuring object 12. At least one positioning visual module 17 captures the image information of the object to be tested 12 and transmits it to the control module 18 to cause the control module 18 to perform a positioning process. After the positioning process is completed, the process proceeds to step S2. For example, in the embodiment, the positioning visual module 17 located at the two ends of the gantry 11 captures the image information of the object to be tested 12 and transmits the image information to the control module 18, so that the control module 18 performs a positioning process.

However, in the actual test, at least one positioning visual module 17 captures the image information of the object to be tested 12, so that the control module 18 performs the positioning process.

In step S2, a first coordinate system and a second coordinate system are obtained. The control module 18 controls the multi-axis displacement module 13 according to the image information of step S1 to move the probe module 14 above the object to be tested 12. For example, the first axial unit 130 provides a first axial movement, the second axial unit 131 provides a second axial movement, and the third axial unit 132 provides a third axial movement. The first axial movement to the third axial movement causes the probe module 14 to approach the portion to be tested 120 of the object 12 to be tested. In the actual case, the first axial movement, the second axial movement and the third axial movement are selectively performed, and the non-first axial movement to the third axial movement is required. For example, the first axial movement can be an X-axis movement. The second axial movement can be a Y-axis movement. The third axial movement can be a Z-axis movement or a vertical movement.

If further illustrated, as shown in FIG. 3, the monitoring visual module 15 captures the probe image information of the probe 140 and transmits the probe image information to the control module 18 to cause the control module 18 to calculate. The first horizontal coordinate value of the first coordinate system is obtained; the monitoring visual module 15 captures the image information to be tested of the to-be-tested parts 120, and transmits the image information to be tested to the control module 18 to make the control mode Group 18 calculates the second coordinate system The second horizontal coordinate value.

For example, the visual unit 150 captures the probe image information or the image information to be tested, and the control module 18 determines whether to adjust the position of the visual unit 150 according to the probe image information or the image information to be tested. At the position of the unit 150, the control module 18 controls the displacement unit 151 to cause the displacement unit 151 to adjust the position of the visual unit 150.

Since the probes 140 are plural, the probes 140 are the first probes 140 to the Nth probes 140, and N is a constant. The visual vision unit 150 is moved to capture the first probes 140. The first tip image information of the tip. The vision unit 150 is moved to capture the Nth tip image information of the tip of the Nth probe 140. Calculating the horizontal coordinate value of a probe coordinate system according to the first tip image information and the Nth tip image information, and controlling the position of the multi-axis displacement module 13 with the control module 18, the probe coordinate system Is the first horizontal coordinate value of the first coordinate system.

Similarly, the to-be-tested parts 120 are the first to-be-tested part 120 to the Nth to-be-tested part 120, and the monitoring visual module 15 avoids the needle tip of the first probe 140. The multi-axis displacement module 13 causes the probe module 14 to leave the field of view of the monitoring visual module 15 to capture the first image information to be tested of the first portion to be tested 120, and monitor the visual module 15 Avoiding the N-tip of the N-th probe 140 to capture the Nth image to be tested of the Nth portion to be tested 120, according to the first image information to be tested and the information of the Nth image to be tested, and matching the control mode The group 18 controls the position of the multi-axial displacement module 13, and causes the control module 18 to calculate the horizontal coordinate value of the coordinate system of the part to be tested, and the coordinate of the part to be tested is the second horizontal coordinate value of the second coordinate system. .

In step S3, it is determined whether the probe module 14 needs to adjust the position relative to the object to be tested 12. The control module 18 calculates the offset between the first horizontal coordinate value and the second horizontal coordinate value according to the first horizontal coordinate value of the first coordinate system and the second horizontal coordinate value of the second coordinate system, if any When the offset is generated, the position of the probe module 14 is adjusted so that the horizontal position of the probe module 14 conforms to the horizontal position of the portion to be tested 120.

For example, if an offset is generated, the offset is an angular deviation, and the angle adjustment module 16 provides an angular movement even if the probe module 14 is rotated by an angle. If the offset is a horizontal offset, that is, a first axial or second axial offset, the multi-axial displacement module 13 provides a first axial movement or a second axial movement, and the probe mode is The group 14 is moved and the probe 140 is positioned above the site to be tested 120.

Referring to FIG. 2 and FIG. 4, in step S4, the vertical coordinate value of the first coordinate system relative to the second coordinate system is obtained. The probe module 14 is vertically moved and monitored by the monitoring visual module 15. When the probe 140 is horizontally slid, the probe module 14 stops moving, and it is judged that the probe 140 has contacted the portion to be tested 120. The vertical coordinate value of the first coordinate system relative to the second coordinate system is obtained.

For example, the multi-axis displacement module 13 moves the probe module 14 vertically, and the monitoring visual module 15 monitors the probe 140. When the control module 18 detects the monitoring of the visual module 15 When the probe 140 has a horizontal slip in the probe image information, the control module 18 stops the multi-axis displacement module 13 from being activated, and then the probe module 14 stops moving. At this time, it should be judged that the probe 140 has been Contact the site to be tested 120. The distance that the control module 18 is vertically moved by the probe module 14 to calculate the relative coordinate of the first coordinate system The vertical coordinate value of the two coordinate system.

As described above, the present invention uses the monitoring visual module 15 to capture the probe image information, the image information of the portion to be tested, and the image information of the probe 140 to generate horizontal slip, so that the control module 18 calculates the first level. The coordinate value, the second horizontal coordinate value, the offset and the vertical coordinate value, thereby adjusting the relative positions of the probe 140 of the probe module 14 and the portion to be tested 120, and ensuring that the probe 140 is in contact with the portion to be tested. 120, and the probe 140 can perform a detection procedure on the site to be tested 120.
