[0029] The adsorption device in the pressing plate 204 is started to adsorb and fix the tape on the front side of the pressing plate 204, and the PCB board is fixed in front of the pressing plate 204. The first electric rod 202 is started to control the installation box 201 to move forward and move toward the PCB board; then the PCB board contacts the moving plate 206 through the tape, and the installation box 201 continues to move forward. The moving plate 206 is squeezed by the PCB board and retracted into the installation box 201, and the first spring 207 is compressed.

[0032] See also Figure 1 As shown, it also includes: a limiting frame 601 fixedly mounted on the second mounting seat 103 , and the limiting frame 601 is arranged on the upper front side of the clamping plate 303 .

[0033] The second motor 310 is started to control the first screw rod 306 to rotate, and the two moving seats 301 are controlled to move upward synchronously. Among the clamping plates 303 on the left and right sides, the control block 309 on the clamping plate 303 located at the upper position contacts the extrusion block 308, so that the clamping plate 303 is controlled to rotate, and the third torsion spring 304 is twisted. Therefore, the two clamping plates 303 on the same side are separated from each other, and the PCB board is placed between the four clamping plates 303, and the PCB board is abutted against the limiting frame 601 for position positioning. After completion, the first screw rod 306 is controlled to reverse and move the moving seat 301 downward. The control block 309 is separated from the extrusion block 308, and the third torsion spring 304 is deformed again, and the two clamping plates 303 on the same side are controlled to clamp and fix the PCB board; if it is necessary to hem the two sides of the PCB board, when the hemming process is completed on one side of the PCB board, the first motor 305 can be started to control the rotating seat 302 to rotate, and the PCB board is flipped 180 degrees, and then the other side of the PCB board can be hemmed.

[0034] See also Figure 1 , Figure 6 and Figure 7As shown, it also includes: a matching mechanism disposed on the second mounting seat 103, the matching mechanism is used to match with the hemming mechanism to improve the hemming effect of the hemming mechanism on the PCB board; The matching mechanism includes: a top strip 401 slidably mounted on the second mounting seat 103, the top strip 401 being arranged on the front side of the clamping plate 303; a pull rod 402 slidably mounted on the left and right sides of the second mounting seat 103, the pull rod 402 being fixed to the left and right ends of the top strip 401; a second spring 403 arranged on the pull rod 402, the two ends of the second spring 403 being respectively fixed to the pull rod 402 and the second mounting seat 103; a rotating arm 404 rotatably mounted on the left and right sides of the second mounting seat 103; telescopic ends 405 slidably mounted on the upper ends of the two rotating arms 404, the upper ends of the two telescopic ends 405 being rotatably mounted to the rear ends of the two pull rods 402 respectively; a top rod 406 slidably mounted on the left and right sides of the second mounting seat 103, the rear ends of the two top rods 406 being respectively fixed to the left and right sides of the mounting box 201, the front ends of the two top rods 406 being respectively in contact with the lower ends of the two rotating arms 404, and the movement of the top rod 406 will control the pull rod 402 to move in the opposite direction through the rotating arm 404.

[0035] When the installation box 201 moves forward, the installation box 201 drives the top rod 406 to move forward, and the top rod 406 will contact the lower end of the rotating arm 404 to control the rotation of the rotating arm 404. The upper end of the rotating arm 404 pulls the pull rod 402 and the top bar 401 backward through the telescopic end 405. At the same time, the telescopic end 405 slides relative to the rotating arm 404, and the second spring 403 is compressed, so that the top bar 401 can be against the front side of the PCB board. Subsequently, the bottom end of the rotating arm 404 moves to the upper side of the top rod 406, thereby limiting the rotation of the rotating arm 404. Due to the friction between the small rotating arm 404 and the top rod 406, a roller can be set at the bottom end of the rotating arm 404. In this way, when the hemming mechanism is hemming the PCB board, the PCB board will not be pushed forward by the hemming mechanism, so that the hemming mechanism can hem the PCB board more accurately, improve the hemming quality, and prevent the PCB board from moving relative to the clamping plate 303, thereby preventing the PCB board from being scratched and damaged by the clamping plate 303; when the installation box 201 moves backward to return to its position, the top rod 406 disengages from the lower end of the rotating arm 404, and the second spring 403 moves the top bar 401 forward to return to its position.

[0038] In the gluing mechanism, the adsorption plate 501, the support plate 506, the clamping plate 5022 and the clamping frame 5021 are all made of non-stick adhesive material.

[0039] The end of the tape roll is pulled out and passed through the two fixing members 502. The fixing member 502 on the left is first controlled to clamp the tape, and the third motor 504 is started to control the fixing member 502 on the left to move the tape to the left and pull the tape out of the tape roll. Then, the fixing member 502 on the right is controlled to fix the tape, and the electric knife 505 is controlled to rotate and cut the tape. Finally, the fixing member 502 on the left is controlled to release the tape and move it to the left to the leftmost side of the third mounting seat 104 and leave from the top of the adsorption plate 501, so that the cut tape falls on the adsorption plate 501, and the adsorption plate 501 is controlled to adsorb and fix it. At the same time, the new end of the tape is located on the support plate 506 and is fixed by the fixing member 502 on the right.
