[0025] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1 and Figure 2 The refrigerator liner laser punching device shown includes:

[0027] Workbench 1, a conveyor belt 13 parallel to each other is respectively provided on both sides of the central axis of the square table top of the workbench 1, two grooves are provided between the two conveyor belts 13, a front baffle 111 that can swing back and forth is provided in the front groove, and a rear baffle 112 that can swing back and forth is provided in the rear groove. At least a pair of side baffles 12 that can move back and forth are provided on both sides of the workbench 1 within the two grooves, and a first driving component 14 is provided at the bottom of the side baffle 12, and a driving motor 11 is respectively provided on one side of the front baffle 111 and the rear baffle 112. A photoelectric sensor 16 is provided at the position of the edge of the square table top facing the front baffle 111, and a second driving component 15 is installed under the workbench 1 table top at the groove; Table 1 serves as a stable support for the equipment and can be adjusted and leveled individually without moving the equipment structure. During the actual punching work of the refrigerator liner 4, the number of side baffles 12 can be adjusted according to the model of the refrigerator liner. The number of workbenches 1 can be adjusted if necessary. For example, when the refrigerator liner 4 is too long and exceeds the maximum distance between the front baffle 111 and the rear baffle 112, multiple workbenches 1 can be spliced together. Two grooves, one in front and one in the rear, are selected on the spliced workbench according to the model of the liner. The front baffle 111 is installed in the front groove and the rear baffle 112 is installed in the rear groove. Corresponding drive motors 11 and second drive components 15 are respectively provided on one side of the front baffle 111 and the rear baffle 112 to achieve punching of refrigerator liner 4 of any model.

[0028] The punching robot 2 includes at least two robots symmetrically arranged on both sides of the workbench 1. During the punching process of the refrigerator liner 4, the number of punching robots on both sides of the workbench can be adjusted according to the actual needs of the refrigerator liner punching.

[0029] Specifically, the conveyor belts 13 are a first conveyor belt 131 and a second conveyor belt 132. Both conveyor belts 13 are made of the same material and width. The first conveyor belt 131 is mounted to the left of the countertop's central axis, while the second conveyor belt 132 is mounted to the right. The synchronized movement of the two conveyor belts 13 drives the refrigerator liner. After the program is started, the conveyor belts 13 begin to operate. The truss manipulator 3 places the refrigerator liner 4 on the conveyor belts 13, which then drives the liner 4. The conveyor belts 13 stop operating when the liner 4 reaches the front baffle 111. Once the liner 4 is punched, the conveyor belts 13 resume operation.

[0030] Specifically, the front baffle 111 and the rear baffle 112 have the same structure and size, the height of the front baffle 111 and the rear baffle 112 is less than the length of the groove, and the front baffle 111 and the rear baffle 112 are respectively provided with corresponding drive motors 11, and the front baffle 111 and the rear baffle 112 are reciprocatingly rotated by their respective drive motors 11. When the drive motor 11 of the front baffle 111 drives the front baffle 111 to rotate counterclockwise, the front baffle 111 protrudes from the groove, and when the front baffle 111 is driven to rotate clockwise, the front baffle 111 rotates back into the groove; the rotation direction of the rear baffle 112 is opposite to that of the front baffle 111. Before punching the refrigerator liner 4, the front baffle 111's own drive motor 11 drives the front baffle 111 to rotate in a counterclockwise direction, causing the front baffle 111 to protrude from the groove and fix the front side of the refrigerator liner 4. After punching the refrigerator liner 4, the front baffle 111's own drive motor 11 drives the front baffle 111 to rotate in a clockwise direction, causing the front baffle 111 to rotate back from the front side of the refrigerator liner 4 to the inside of the groove. The rotation direction of the rear baffle 112 is opposite to that of the front baffle 111. When the refrigerator liner 4 reaches the front baffle 111, the rear baffle 112's own drive motor 11 drives the rear baffle 112 to rotate in a clockwise direction, causing the rear baffle 112 to protrude from the groove and fix the rear side of the refrigerator liner 4. After punching the refrigerator liner 4, the rear baffle 112 rotates back in a counterclockwise direction to the inside of the groove.

[0031] Specifically, the front baffle 111 and the rear baffle 112 are fixed to the rotating shafts of their respective drive motors 11, and the front baffle 111 and the rear baffle 112 are connected to the second drive assembly 15 via their respective drive motors 11. The second drive assembly 15 drives the corresponding front baffle 111 or rear baffle 112 to move forward and backward. The drive connection method of the front baffle 111 and the rear baffle 112 is the same. Taking the front baffle 111 as an example, the connection relationship between the front baffle 111, the drive motor 11 of the front baffle 111, and the second drive assembly 15 of the front baffle 111 is as follows: Figure 4 shown.

[0032] Specifically, if Figure 4 The second drive assembly 15 shown includes a second drive module 151 and a second telescopic rod 152. The second drive module is fixed below the workbench 1. One end of the second telescopic rod 152 is connected to the second drive module 151, and the drive motor 11 is fixed to the other end of the second telescopic rod 152. Depending on the model of the refrigerator liner 4, the second drive module 151 drives the second telescopic rod 152 to extend or retract, driving the corresponding drive motor 11 to move forward and backward, thereby driving the front baffle 111 or the rear baffle 112 to move forward and backward.

[0033] Specifically, the side guards 12 are vertical guards, parallel to the central axis of the table, and installed in corresponding chutes on both sides of the workbench 1. A pair of side guards 12 are a left guard 121 and a right guard 122. The left guard 121 and the right guard 122 have the same structure and size. The left guard 121 is installed on the left side of the first conveyor belt 131, and the right guard 122 is installed on the right side of the second conveyor belt 132. The left guard 121 and the right guard 122 move left and right along the corresponding chutes.

[0034] Specifically, the chute is perpendicular to the central axis of the tabletop, and its length is less than the distance between the conveyor belt 13 and the edge of the workbench 1. Before punching the refrigerator liner 4, the left and right baffles 121 and 122 move back to the sides of the workbench 1. After the refrigerator liner 4 reaches the position of the front baffle 111, the left and right baffles 121 and 122 move toward each other, securing the refrigerator liner 4 from the left and right sides. After punching the refrigerator liner, the left and right baffles 121 and 122 move back again to the sides of the workbench 1, and the first drive assembly 14 drives the corresponding side baffles 12 to move left and right.

[0035] Specifically, if Figure 3As shown, the first drive assembly 14 includes a first drive module 141, a first telescopic rod 142 and a first connecting rod 143. The first drive module 141 is fixedly installed below the square table top of the workbench 1, and the first connecting rod 143 is vertically installed in the corresponding slide groove of the workbench 1. One end of the first connecting rod 143 is fixedly connected to the bottom of the corresponding side baffle 12, and the other end of the first connecting rod 143 is vertically fixedly connected to the first telescopic rod 142. The first telescopic rod 142 is connected to the first drive module 221 parallel to the corresponding slide groove.

[0036] Specifically, the photoelectric sensor 16 includes a photoelectric sensing module 161 and a second connecting rod 162. The photoelectric sensing module 161 is mounted on the edge of the workbench 1 on one side and corresponds to the side of the front baffle 111. The second connecting rod 162 is L-shaped and connects the photoelectric sensing module 161 to the drive motor 11 corresponding to the front baffle 111. The extension and contraction of the second telescopic rod 152 drives the drive motor 11 corresponding to the front baffle 111 to move back and forth, thereby driving the front baffle 111 and the photoelectric sensing module 161 fixed to the second connecting rod 162 to move synchronously, allowing the photoelectric sensing module 161 to continuously sense changes in light at the front baffle 111. When the refrigerator liner 4 reaches the front baffle 111, the photoelectric sensor 16 is triggered, the conveyor belt 13 stops working, and the position reset program is activated, which controls the side baffles 12 to move toward each other and the front and rear baffles 11 to move back and forth to secure the refrigerator liner 4. During the actual punching of the refrigerator liner 4 , the front baffle 111 , the rear baffle 112 and the side baffle 12 can perform corresponding translational motions according to the punching requirements of the refrigerator liner 4 to adjust the position of the refrigerator liner 4 on the workbench 1 .

[0037] Specifically, the punching robot 2 is equipped with a laser generator and a water chiller. Once the photoelectric sensor 16 is triggered, the refrigerator liner laser punching program is activated, and the punching robot 2 begins operation. The program controls the laser generator and the water chiller to adjust the laser emission intensity and direction of the punching robot 2, achieving automated punching of the refrigerator liner 4.

[0038] The specific working state of the refrigerator liner laser punching equipment provided by the utility model is as follows:

[0039] Before punching the refrigerator liner 4, workers select the punching area based on the model of the refrigerator liner 4 on the 3D model of the refrigerator liner 4, perform a preliminary simulation of the laser punching trajectory of the refrigerator liner, and generate a punching program for the refrigerator liner 4. The program is then imported into the refrigerator liner laser punching equipment, which reads the program and transmits the corresponding position reset program based on the model of the refrigerator liner 4 to the first and second drive assemblies 14, 15. The second drive assembly 15 adjusts the front and rear baffles 111, 112, and rotates the front baffle 111 onto the workbench 1. The first drive assembly 14 controls the movement of the side baffles 12 to the sides of the workbench 1. After the baffles are adjusted, the truss robot 3 places the refrigerator liner 4 onto the conveyor belt 13. The refrigerator liner 4 moves forward along the conveyor belt 13 until it reaches the front baffle 111, which blocks the liner 4 from further movement. The photoelectric sensor 16 is triggered, causing the conveyor belt 13 to stop and the position reset program to activate. The side baffles 12, depending on the size of the refrigerator liner 4, move toward the center of the workbench 1, securing it from both sides. The rear baffle 112 rotates to the workbench 1 surface to secure the rear of the refrigerator liner 4. Once the refrigerator liner 4 is secured, the laser punching program is activated, controlling the punching robot 2 to punch the refrigerator liner 4. Once the liner is punched, the front and rear baffles 11 rotate into the workbench grooves, and the side baffles 12 move to the sides of the workbench. The conveyor belt 13 resumes operation, transporting the refrigerator liner 4 to the outside of the workbench.

[0040] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
