[0025] like Figure 4 、 Figure 6 and Figure 7 As shown, in another embodiment of the present invention, the cleaning mechanism 4 includes a support frame 401, the support frame 401 is mounted on one end of the upper surface of the workbench 1, and a connecting frame 405 is movably mounted on the lower end of the inner part of the support frame 401, and support plates 406 are movably mounted on both sides of the lower end of the inner part of the connecting frame 405, and the front ends of the support plates 406 on the side close to each other are respectively mounted with drying lamps 408, and the rear ends of the support plates 406 on the side close to each other are respectively mounted with a number of movable rollers 407, and the drying lamps 408 are parallel to the movable rollers 407 and the raw material 3. An electric slide rail 402 is mounted in the middle of the lower surface of the support frame 401, and a slider 403 is mounted on the No. 1 electric slide rail 402. The inner part of the No. 1 slider 403 is mounted There is a No. 1 cylinder 404, the output end of the No. 1 cylinder 404 is connected to the connecting frame 405, and the outer side of the movable roller 407 is wrapped with a dust-free cloth. Rotating blocks 410 are movably installed on both sides of the connecting frame 405, and the ends of the rotating blocks 410 close to each other are respectively connected to the support plates 406. A motor 409 is installed on one side of the connecting frame 405, and the motor 409 is connected to the rotating block 410. Temporary storage boxes 411 are respectively provided at both ends of the inner upper surface of the support frame 401, and a number of dripping pipes 412 are respectively installed through the inner lower end of the temporary storage box 411. The dripping pipes 412 and the movable roller 407 are parallel to each other, and a liquid inlet pipe 413 is respectively installed through the end of the temporary storage box 411 close to the motor 409.

[0026] When the connecting frame 405 is located at the front end of the supporting frame 401 and moves from front to back, the drying lamp 408 is in front and the movable roller 407 is at the back. At this time, the alcohol can enter the interior of the temporary storage box 411 through the liquid inlet pipe 413 at the rear end.

[0032] When in use, first, when the raw material 3 moves to the lower end of the support frame 401, the No. 1 electric slide 402 cooperates with the No. 1 slider 403 to move the connecting frame 405 to the front end, and then the No. 1 cylinder 404 pushes the connecting frame 405 to move downward, so that the connecting frame 405 drives the movable roller 407 to connect with the surface of the raw material 3, and then after the movable roller 407 and the surface of the raw material 3 are connected, the No. 1 slider 403 can drive the No. 1 cylinder 404 and the movable roller 407 to move, so that the first movable roller 407 at the rear end drives the wet dust-free cloth to wipe and clean the surface of the raw material 3, and then the second movable roller 407 at the rear end The dry dust-free cloth is used to perform a secondary cleaning of water droplets retained on the surface of the raw material 3, and then the surface of the raw material 3 is dried and cleaned by the drying lamp 408. After the drying of the raw material 3 is completed, the conveyor belt 2 drives the raw material 3 to move to the lower end of the support block 502, and then the No. 2 cylinder 501 will pull the support block 502 to move downward, allowing the support block 502 to drive the steel mesh 503 and the surface of the raw material 3 to fit together, and then the No. 2 electric slide rail 504 can cooperate with the No. 2 slider 505 to drive the scraper 506 to slide on the upper end of the steel mesh 503, so that the scraper 506 cooperates with the steel mesh 503 to print solder paste on the raw material 3.
