[0039] When clamping the circuit board, first, place the circuit board on the upper surface of the centering support frame 513, then drive the two L-shaped limiting plates 502 on the X-axis bidirectional screw rod group 501 to move inward, so that the rollers 506 are clamped on the opposite sides of the circuit board, and after contacting, drive the second spring 507 to be extruded;

[0040] When the first sensing block 508 and the second sensing block 512 on both sides simultaneously contact and send a command to the processor 511, the X-axis bidirectional screw rod group 501 stops moving;

[0041] Then start the first Y-axis bidirectional screw rod group 514 to drive the clamping block 505 to clamp inward, thereby completing the centering and clamping operation of the circuit board;

[0042] When processing circuit boards of different specifications and sizes, the center point can be limited, which is convenient for path planning of the detection mechanism 1;

[0043] In addition, under the action of the second Y-axis screw rod group 515 and the rollers 506, the circuit board can be smoothly and quickly translated to the detection area, and when translated to the top end of the second Y-axis screw rod group 515, it is just located at the center position of the detection area, which is also convenient for the detection mechanism 1 to realize quick positioning when the synchronous scanning mechanism 4 moves, thereby improving the work efficiency.

[0044] Working principle:

[0045] When the scanning mechanism 4 automatically scans the silver paste line on the circuit board fixed on the centering and limiting mechanism 5, first, the camera 415 obtains the overall distribution of the silver paste line on the circuit board on the centering and limiting mechanism 5 through the low-power lens 409, and obtains the overall image on the computer 7; when an abnormal position is observed, after determining the detection range on the computer 7, move to the range under the action of the second Y-axis slide rail group 401 and the second X-axis slide rail group 402, then drive the gear 405 to rotate under the action of the servo motor 404, and then drive the fan-shaped support plate 407 to move, switch to the second high-power lens 408, and magnify the selected area position, so as to obtain detailed damage information, which is suitable for small-range circuit boards, and also facilitates the silver paste pen 411 to realize accurate repair, strengthens the repair efficiency, and optimizes the repair effect;

[0046] In addition, under the action of the lamp strip 416, when transferred to the second high-power lens 408 for use, the first arc surface induction sheet 406 and the second arc surface induction sheet 410 are in contact, and after processing, a signal is sent to the lamp strip switch 417 to control the lamp strip 416 to turn on, thereby making up for the defect of insufficient light when the second high-power lens 408 is used, and ensuring the detection effect;

[0047] When the circuit board moves along the centering and limiting mechanism 5, it can be transferred from the scanning area to the detection area, and the movement path of the synchronous scanning mechanism 4 is synchronized, under the action of the air-drying mechanism 2, the silver paste line is quickly air-dried, and then under the action of the first Y-axis slide rail group 101 and the first X-axis slide rail group 102, the first probe 106 is synchronously driven to contact the detection point at the maintenance position, and the first high-power lens 107 continuously monitors the environment around the detection point and displays on the computer 7, then the second probe 110 is held by hand to contact the silver paste line around the detection point, and the resistance value is displayed on the display 108, thereby realizing the rapid measurement of the maintenance state of the circuit board and ensuring the maintenance effect of the circuit board;

[0048] In addition, the marker pen core 117 can be used to mark the defect position in real time by actuating the dial block 114, and the marker pen core 117 can be returned to the home position under the action of the first spring 113, thereby playing the role of quickly marking the damaged position by using the first high-power lens 107, and facilitating the rapid positioning of the secondary scanning and repair;

[0049] Subsequently, when clamping the circuit board, first, place the circuit board on the upper surface of the centering support frame 513, then move the two L-shaped limiting plates 502 inward under the action of the X-axis bidirectional screw group 501, so that the rollers 506 are clamped on the opposite sides of the circuit board, and after contacting, the second spring 507 is extruded;

[0050] When the first induction block 508 and the second induction block 512 on both sides contact at the same time and send a command to the processor 511, the X-axis bidirectional screw group 501 stops moving, and then the first Y-axis bidirectional screw group 514 is started to drive the clamping block 505 to clamp inward, thereby completing the centering and clamping operation of the circuit board, which not only adapts to circuit boards of different specifications, but also limits the center point, facilitating the path planning of the detection mechanism 1, and under the action of the second Y-axis screw group 515 and the rollers 506, the circuit board can be smoothly and quickly translated to the detection area, and when translated to the top end of the second Y-axis screw group 515, it is just located at the center position of the detection area, which also facilitates the rapid positioning when the detection mechanism 1 synchronously scans the movement trajectory of the scanning mechanism 4, thereby improving the work efficiency.
