[0021] Please see attached Figure 1 -Attached Figure 4A circuit board positioning device comprises a workbench 1, a side baffle 2 with a ring structure is fixedly installed on the top of the workbench 1, a top plate 3 is fixedly installed on the top of the side baffle 2, four mutually perpendicular slide grooves 4 are opened on the top of the top plate 3, a T-shaped slider 5 is slidably installed in each slide groove 4, a groove is opened on the top of each T-shaped slider 5, a pressure sensor 11 is fixedly installed in each groove, the detection end of each pressure sensor 11 is facing the middle of the top plate 3, and a warning light 12 is fixedly installed on the top of each T-shaped slider 5. By setting the device, the circuit board is positioned. When fixing, it is only necessary to place the circuit board in the middle of the top of the top plate 3, and control the two opposing T-shaped sliders 5 to slide synchronously through the control panel 13, so as to clamp the circuit board on all sides and position the circuit board in the middle of the top plate 3. The operation is simple and convenient. At the same time, during the clamping process, the clamping force of the T-shaped slider 5 on the circuit board is detected by the pressure sensor 11, and the corresponding threshold is set according to the circuit boards of different materials. When the warning light 12 is on, the sliding of the corresponding T-shaped slider 5 is stopped, which effectively avoids damage to the circuit board during the clamping and fixing process and improves the qualified rate of the equipment after processing.

[0022] Please see attached Figure 1 and attached Figure 2 In a preferred embodiment, a first bidirectional screw rod 9 and a second bidirectional screw rod 10 are perpendicularly arranged in the side baffle 2, and the two ends of the first bidirectional screw rod 9 and the second bidirectional screw rod 10 are rotatably installed with the corresponding side in the side baffle 2, and the first bidirectional screw rod 9 and the second bidirectional screw rod 10 respectively pass through the outer surfaces of the two T-shaped sliders 5 and are threadedly connected thereto, and servo motors 6 are fixedly installed on two adjacent sides of the outer surface of the side baffle 2, and the output ends of the two servo motors 6 are respectively fixedly installed with the rotation center of one end of the first bidirectional screw rod 9 and the second bidirectional screw rod 10. By arranging the first bidirectional screw rod 9 and the second bidirectional screw rod 10 to have symmetrical external threads on the surface, the two ends of the first bidirectional screw rod 9 respectively drive the two T-shaped sliders 5 that slide forward and backward through the symmetrical external threads, and the two ends of the second bidirectional screw rod 10 respectively drive the two T-shaped sliders 5 that slide left and right through the symmetrical external threads, so that the two opposing T-shaped sliders 5 can synchronously slide toward the middle of the top of the top plate 3, and at the same time clamp the two opposite sides of the circuit board, thereby improving the accuracy of the equipment clamping and positioning.

[0023] Please see attached Figure 3 and attached Figure 4In a preferred embodiment, a control console 13 is fixedly installed on one side of the side baffle 2, two sets of scale lines 7 that are perpendicular to each other are opened on the top of the side baffle 2, and two maintenance windows 8 that penetrate the surface of the side baffle 2 are opened on one side. The control console 13 is electrically connected to the two servo motors 6 through wires, and the control console 13 is provided with two start and stop buttons for controlling the two servo motors 6. When the warning light 12 is on, the operation of the corresponding servo motor 6 is stopped in time, thereby improving the convenience of equipment operation; the scale lines 7 can be used to measure the length and width of the circuit board, and the maintenance window 8 can be used for daily maintenance of the transmission mechanism, thereby improving the practicality of the equipment.

[0024] Working principle: When in use, first place the circuit board on the top of the top plate 3, and the four sides are roughly parallel to the T-shaped sliders 5, and then control the two servo motors 6 to start through the start-stop button set on the control panel 13, and then drive the first bidirectional screw rod 9 and the second bidirectional screw rod 10 to rotate. The first bidirectional screw rod 9 and the second bidirectional screw rod 10 drive the four T-shaped sliders 5 to clamp the circuit board around and position it in the middle of the top of the top plate 3. When the extrusion pressure around the circuit board reaches an appropriate level, the pressure sensor 11 sends a relevant signal in time, the warning light 12 lights up, and the operation of the two servo motors 6 is stopped immediately to avoid excessive clamping force, which may cause damage to the circuit board and improve the qualified rate of the equipment after processing.

[0025] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
