[0019] The embodiments of the present application will be described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0021] As Figure 1As shown, a laser cleaning device comprises a workbench 1, a first carrier 2 and a second carrier 3, the first carrier 2 and the second carrier 3 are both rotationally connected to the top of the workbench 1, and both are used to carry a piece of workpiece to be cleaned, a cleaning mechanism 4 is located between the first carrier 2 and the second carrier 3, and is used to simultaneously laser clean the side surfaces of the two workpieces, while the cleaning mechanism 4 cleans the top of one of the workpieces, the other carrier changes the workpiece, so that the laser cleaning device can continuously work efficiently, reduce the non-working time of the cleaning mechanism 4, and greatly improve the laser cleaning efficiency of the workpiece.

[0022] The top of the workbench 1 is configured as a planar structure, so that the top of the workbench 1 can play a role of carrying and supporting. The top of the workbench 1 is fixedly provided with a first sliding rail 11 and a second sliding rail 12, both of which extend along a first direction, that is, the first sliding rail 11 and the second sliding rail 12 are arranged in parallel. The same end of the first sliding rail 11 and the second sliding rail 12 along the first direction is the input end, and the opposite end is the output end.

[0023] The first carrier 2 is slidingly connected to the first sliding rail 11, and the second carrier 3 is slidingly connected to the second sliding rail 12. The first carrier 2 receives a first workpiece 100 from the input end of the first sliding rail 11 in the last process, and the second carrier 3 receives a second workpiece 200 from the input end of the second sliding rail 12 by manual operation in the last process. In this embodiment, the first workpiece 100 and the second workpiece 200 are manually fed at the input end of the first sliding rail 11 and the input end of the second sliding rail 12. The first carrier 2 and the second carrier 3 respectively carry a workpiece from the input end to the output end. The cleaning mechanism 4 is located near the output end of the first sliding rail 11 and the second sliding rail 12. After cleaning, the two workpieces are transported to the input end and replaced by manual operation. The cleaning mechanism 4 has multiple degrees of freedom, so that the cleaning end of the cleaning mechanism 4 can move between the two workpieces to simultaneously laser clean the side walls of the two workpieces, or move to the top of the workpiece to laser clean the top of the two workpieces respectively.

[0024] The first sliding rail 11 is slidingly connected with a first sliding table 13, and the second sliding rail 12 is slidingly connected with a second sliding table 14. The first carrier 2 is rotationally connected to the first sliding table 13 by a motor, and the second carrier 3 is rotationally connected to the second sliding table 14 by a motor. The rotational central axis of the first carrier 2 and the rotational central axis of the second carrier 3 are both arranged in a vertical direction. That is, the first carrier 2 and the second carrier 3 drive the workpieces carried thereby to rotate along a vertical axis. The first carrier 2 and the second carrier 3 rotate to adjust the position of the workpieces, so that the workpieces are within the laser cleaning range of the cleaning mechanism 4.

[0025] As Figures 2 to 4As shown, the top of the first carrier 2 is constructed as a horizontal plane for carrying the first workpiece 100.

The top of the first carrier 2 is provided with a first positioning notch 21, a first guide groove 22, and a second guide groove 23, all of which are connected to the first accommodating cavity. The first positioning notch 21 deviates from the rotation center of the first carrier 2. The first guide groove 22 and the second guide groove 23 are both constructed in the shape of long strips. The ends of the first guide groove 22 and the second guide groove 23 are both connected to the first positioning notch 21. Preferably, the first guide groove 22 and the first guide groove 22 are perpendicular to each other.

The sliding direction of the first limiting assembly 24 is parallel to the length direction of the first guide groove 22, and the sliding direction of the second limiting assembly 29 is parallel to the length direction of the second guide groove 23.

[0026] The first limiting assembly 24 includes a first cylinder and a first limiting member. The cylinder body of the first cylinder is slidably connected to the bottom surface of the first carrier 2 through a guide rail. The first limiting member is fixed to the piston rod of the first cylinder. The piston rod of the first cylinder extends upward in the vertical direction to push the first limiting member out of the first guide groove 22. The first limiting member abuts the edge of the first workpiece 100 and pushes the workpiece toward the first positioning notch 21.

[0027] Preferably, there are two first guide grooves 22, and the two first guide grooves 22 are parallel to each other. The piston rod of the first cylinder is fixed to a first bracket, and two first stoppers are fixed to the first bracket. The two first stoppers correspond one to one with the two first guide grooves 22, that is, one first stopper moves within each guide groove. The two first stoppers push the first workpiece 100 in parallel to prevent angular deflection of the first workpiece 100 during movement along the length of the first guide grooves 22.

[0028] Preferably, there are two second guide grooves 23, and the two second guide grooves 23 are parallel to each other. The piston rod of the second cylinder is fixed to a second bracket, and two second stoppers are fixed to the second bracket. The two second stoppers correspond one-to-one with the two second guide grooves 23, that is, one second stopper moves within two guide grooves. The two second stoppers push the first workpiece 100 in parallel to prevent angular deflection of the first workpiece 100 during movement along the length of the second guide grooves 23.

[0029] The top of the first carrier 2 is slidably connected to a first guide assembly 25. The travel of the first guide assembly 25 is greater than the travel of the first limit assembly 24 and the second limit assembly 29. It is used to guide the first workpiece 100 to within the travel range of the first limit member and the second limit member. The first guide assembly 25 includes a first guide plate 251, a second guide plate 252, and a third guide plate 253.

The second guide plate 252 is slidably connected to the top of the first carrier 2 along the length of the second guide groove 23 via a guide rail. The second guide plate 252 is located between the two second guide grooves 23. The movement direction of the first guide plate 251 and the movement direction of the second guide plate 252 are perpendicular to each other.

[0030] The third guide plate 253 is located at the angle between the first guide plate 251 and the second guide plate 252. The third guide plate 253 moves toward the first positioning notch 21 to push the first workpiece 100 toward the first positioning notch 21. Preferably, the movement direction of the third guide plate 253 forms a 45° angle with the movement direction of the first guide plate 251, and the movement direction of the third guide plate 253 forms a 45° angle with the movement direction of the second guide plate 252.

In other embodiments, multiple first suction ports 26 are provided, all connected to the negative pressure device. Both the first guide plate 251 and the second guide plate 252 have openings that communicate with the first suction port 26. When any of these openings communicate with the first suction port 26, they can serve to absorb the first workpiece 100, allowing the first workpiece 100 to move synchronously with the first guide assembly 25. In this embodiment, the first support plate 27 also has a first suction port 26.

[0032] A first supporting plate 27 is provided at the first positioning notch 21. The tops of the first supporting plate 27, the first guide plate 251, the second guide plate 252, and the third guide plate 253 are all located on the same horizontal plane, so as to facilitate pushing the first workpiece 100 onto the first supporting plate 27.

In this embodiment, the first positioning assemblies 28 are provided in two groups, one of which corresponds to the first limiting assembly 24, and the other corresponds to the second limiting assembly 29. That is, the two groups of first positioning assemblies 28 are perpendicular to each other.
