[0031] Example 2

[0032] Reference Figure 2-5 : This embodiment provides a technical solution based on the first embodiment: the visual positioning marking mechanism 2 includes a support frame 21 fixedly connected to the top of the conveyor belt 1, and a visual laser marker 22 is fixedly connected to one side of the support frame 21. The visual laser marker includes a visual camera, a control center and a laser marker;

[0033] The driving mechanism 3 includes a U-shaped frame 31 fixedly connected to both sides of the conveyor belt 1, a push rod motor 32 is fixed inside the U-shaped frame 31 on one side, and a guide rod 33 is sleeved inside the U-shaped frame 31 on the other side. The bottom ends of the guide rod 33 and the push rod motor 32 are fixedly connected to the same support plate 34, and the control center is electrically connected to the push rod motor 32;

[0034] The clamping and flipping mechanism 4 also includes a plurality of transverse plates 401 fixedly connected to the top of the support plate 34, a transverse plate 402 is fixedly connected to one side of the transverse plate 401, a rack 403 is fixed to the top of the transverse plate 402, one side of the rack 403 is meshed with a gear 411, a plurality of sleeve frames 404 are fixedly connected to the top of the transverse plate 401, and sleeve plates 417 are sleeved inside the sleeve frames 404. The clamping and flipping mechanism reverses the workpiece to achieve double-sided printing;

[0035] The clamping and flipping mechanism 4 also includes two U-shaped frames 408 fixed at the bottom of the conveyor belt 1. Both sides of the U-shaped frame 408 are provided with a slide groove 418. The slide groove 418 is sleeved with a slider 1. One end of each set of screw rods 410 is rotatably connected to the same U-shaped frame 409. The U-shaped frame 409 is fixedly connected to the slider 1. The purpose of the U-shaped frame 2 is to support the screw rod. When the screw rod moves upward, it will also drive the U-shaped frame 2 to move.

[0036] The clamping and flipping mechanism 4 also includes a connecting plate 416 sleeved inside the U-shaped frame 1 408, a plurality of horizontal plates 3 405 are fixed to the bottom of the connecting plate 416, two slide grooves 2 406 are provided on the top of the horizontal plate 3 405, a slider 2 is sleeved inside the slide groove 2 406, the top of the slider 2 is fixedly connected to the moving plate 407, and one side of the sleeve plate 417 is fixedly connected to the horizontal plate 3 405;

[0037] The clamping and flipping mechanism 4 also includes a connecting rod 414 fixedly connected to the top of the U-shaped frame 31, and a plurality of racks 415 are fixed to the bottom of the connecting rod 414. The racks 415 are meshed with the one-way gears moved to the same horizontal line. When the one-way gears move downward, they do not drive the rotating shaft and the clamping block to rotate.

[0038] Working principle: first, the conveyor belt 1 drives the placed workpieces to move, and multiple workpieces are moved to the bottom of the visual laser marker 22. After the visual laser marker 22 recognizes the workpiece, it locates the marking position through vision, and then uses the laser to print the text and icon on the top of the workpiece. After printing, the control center controls the push rod motor 32 to start, and the push rod motor 32 moves the rod upward and retracts it inside. The rod drives the supporting plate 34 connected to it to move upward, and the supporting plate 34 drives the horizontal plate 1 401 and the horizontal plate 2 402 to move upward. The horizontal plate 1 401 synchronously drives the frame 404 fixed to it to move upward, and the horizontal plate 2 402 drives the rack 1 403 fixed thereto to move upward, and the rack 1 403 moves upward to drive the gear 411 meshing therewith to rotate, and the gear 411 synchronously drives the screw 410 fixed thereto to rotate, and the rotation of the screw 410 drives the moving plate 407 and the slider 2 to move in the slide groove 2 406, and the movement of the moving plate 407 synchronously drives the rotating shaft connected thereto to move, and the rotation drives the one-way gear 412 and the clamping block 413 connected thereto to approach the workpiece, and the clamping blocks 413 on both sides of the conveyor belt 1 approach each other and contact the workpiece in the middle, and at this time the one-way gear 412 and the rack 2 415 are located on the same horizontal line, Then the slightly tilted workpiece is corrected during the clamping process and then clamped. After clamping, the top of the cross plate 1 401 and the cross plate 2 402 have contacted the bottom of the cross plate 3 405, and the rack 1 403 no longer drives the gear 411 to rotate. The cross plate 1 401 and the cross plate 2 402 continue to move upward, which will drive the cross plate 3 405 and the connecting plate 416 to move upward. The purpose of the connecting plate 416 is to be placed on the two U-shaped frames 1 408 to support the cross plate 3 405. When the cross plate 3 405 moves upward, it will drag the moving plate 407, the rotating shaft, the one-way gear 412 and the clamping block 413 to move upward. Because the two clamping blocks 413 clamp the workpiece, the workpiece also moves up. During the upward movement, the one-way gear 412 engages with the rack 2 415 and drives the rotating shaft, the clamping block 413 and the workpiece to rotate. When it is flipped to the desired surface, the push rod motor 32 pushes the support plate 34 to move down and reset. Then the rack 1 403 drives the gear 411 and the screw 410 to reverse, so that the moving plate 407 drives the clamping block 413 to move and release the fixation. After the visual laser marker 22 recognizes the features of the workpiece after the reversal, it locates the marking position through vision, and then uses a laser to print text and icons on the workpiece.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
