DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0032] It should be noted that in the description of the present invention, the directions or positional relationships indicated by the terms "front", "rear", "left", "right", "up", "down", "inside", "outside", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention rather than requiring that the present invention must be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. The terms "front", "rear", "left", "right", "up", and "down" used in the description of the present invention refer to the directions in the accompanying drawings, and the terms "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0033] like Figures 1 to 8 As shown, a plate loading and unloading device includes a bracket 1 arranged at a storage position 01 and a processing position 02, and a loading and unloading mechanism 2 that performs three-axis motion is connected to the bracket 1; a clamping mechanism 24 is provided at the output end of the loading and unloading mechanism 2, and the clamping mechanism 24 includes a clamping base plate 241 and a plurality of clamping claw cylinders 242, and the plurality of clamping claw cylinders 242 are arranged on the bottom surface of the clamping base plate 241 along the length direction of the clamping base plate 241, and the clamping claw cylinder 242 has two clamping parts that extend and retract on the same straight line, and the connecting line of the two clamping parts of the same clamping claw cylinder 242 is perpendicular to the length direction of the clamping base plate 241.

[0034] The present application sets a bracket 1 at both the material storage position 01 and the CNC processing position 02, and a channel for the movement of the loading and unloading mechanism 2 is built through the bracket. A plurality of clamping claw cylinders 242 are set on the clamping base plate 241 of the clamping mechanism 24 in the loading and unloading mechanism 2, and the connecting line of the two clamping parts of the same clamping claw cylinder 242 is set perpendicular to the length direction of the clamping base plate 241, so that the plurality of clamping claw cylinders 242 form a square clamping area. The clamping of the plurality of clamping claw cylinders 242 can effectively clamp long-length panels. Compared with the form of suction cup suction, the clamping of the plurality of clamping claw cylinders 242 is more stable. The loading and unloading mechanism 2 capable of three-axis motion can realize the position transfer of the panel after clamping.

[0035] Below through Figures 1 to 8 This application is described in detail.

[0036] like Figures 1 to 3 As shown, the present application builds a passage between the material storage position 01 and the CNC processing position 02 for the loading and unloading mechanism to move. The passage is built by brackets set at the material storage position 01 and the CNC processing position 02. By setting the bracket 1, the loading and unloading mechanism 2 can move between the two brackets 1. The present application is designed for panels with longer lengths. Although panels with longer lengths can be loaded and unloaded manually, it is very inconvenient to load and unload manually due to the long length of the panels, and there will be interference in space. The present application sets a bracket 1 to enable the loading and unloading mechanism 2 to move above the material storage position 01 and the CNC processing position 02, so that the panels can be transported vertically without being interfered by the space in the factory, with high loading and unloading efficiency and high transportation stability.

[0037] Feeding mechanism 2 Figures 3 to 8 As shown, it includes an X-axis moving mechanism 21, a Y-axis moving mechanism 22 and a Z-axis moving mechanism 23, the X-axis moving mechanism 21 is connected to the bracket 1, the Y-axis moving mechanism 22 is connected to the output end of the X-axis moving mechanism 21, the Z-axis moving mechanism 23 is connected to the output end of the Y-axis moving mechanism 22, and the clamping base plate 241 is connected to the output end of the Z-axis moving mechanism 23.

[0038] Furthermore, the X-axis moving mechanism 22 includes a first motor 213, a connecting plate 211 and a first bracket 216. The connecting plate 211 is a connecting piece connecting the brackets 1 at both ends, and is made of a strong and light alloy material. The top surface of the connecting plate 211 is provided with a first slide rail 212 along the length direction of the connecting plate 211, and the bottom surface of the first bracket 216 is provided with a slide groove to cooperate with the first slide rail 212. This design allows the first bracket 216 to slide along the connecting plate 211.

[0039] The top surface of the first bracket 216 is connected to the first motor 213, and the output end of the first motor 213 passes through the bottom of the first bracket 216 and passes through the bottom of the long groove set on the connecting plate 211. The output end of the first motor 213 is also connected to the first gear 214. The bottom surface of the connecting plate 211 is provided with a first rack 215 along its length direction. The first rack 215 and the first gear 214 are meshed. The first motor 213 works to drive the first bracket 216 to move on the connecting plate 211, thereby realizing the transfer between the storage position 01 and the CNC processing position 02.

[0040] In a further embodiment, the Y-axis moving mechanism 22 includes a second motor 223, a second bracket 221, and a second rack 222 arranged along the length direction of the second bracket 221. The top surface of the first bracket 216 is provided with a second slide rail, the second slide rail is perpendicular to the first slide rail, and the bottom surface of the second bracket 221 is provided with a slide groove that matches the second slide rail, so that the second bracket 221 can move along the second slide rail. The top surface of the first bracket 216 is also fixed with the second motor 223 through the bracket, and the output end of the second motor 223 is provided with a second gear to mesh with the second rack 222. When the second motor 223 is working, the second bracket 221 can move in the Y-axis direction on the first bracket.

[0041] In one embodiment, the second bracket 221 is in a U-shape, which includes a bottom plate and two side plates connected to the top two ends of the bottom plate. The three plates can be connected by welding, and the two side plates are parallel. The ends of the side plates extend outward from the outside of the bottom plate, and a slider is provided on the inner side of the side plate at the extension to connect the Z-axis moving mechanism 23. The Z-axis moving mechanism 23 includes a main arm 231. The two sides of the main arm 231 are provided with slide rails to cooperate with the sliders on the side plates, so that the main arm 231 can slide up and down. The bottom end of the main arm 231 is provided with a supporting bottom plate 235. The top surface of the supporting bottom plate 235 is connected to a third cylinder 236. The output end of the third cylinder 236 penetrates the bottom surface of the supporting bottom plate 235 and is connected to the clamping bottom plate 241.

[0042] It is worth mentioning that in this embodiment, the sliding design of the main arm 231 is combined with the telescopic design of the third cylinder 236, so that the movement in the Z-axis direction is a two-stage form, that is, the movement distance of the clamping base plate 241 is the working length of the third cylinder 236 and the sliding length of the main arm 231. This design form realizes large displacement movement in the Z-axis direction, ensuring that the clamping mechanism can extend to the storage position 01 and the processing position 02 in Z.

[0043] Furthermore, the top of the main arm 231 is connected to a limit plate, which can prevent the main arm 231 from transitioning downward and detaching from the second bracket 221. When the main arm 231 slides downward so that the limit plate contacts the second bracket 221, the main arm 231 cannot continue to slide.

[0044] In a further embodiment, the holding mechanism 24 includes a clamping base plate 241 and a plurality of clamping claw cylinders 242, the clamping base plate is connected to the output end of the third cylinder 236, the plurality of clamping claw cylinders 242 are evenly distributed on the bottom surface of the clamping base plate 241 along the length direction of the clamping base plate 241, the plurality of clamping claw cylinders are on the same straight line, the clamping claw cylinder 242 has two clamping parts that are telescopic on the same straight line, and the connecting line of the two clamping parts of the same clamping claw cylinder 242 is perpendicular to the length direction of the clamping base plate 241. The uniform distribution of the clamping claws can ensure the clamping effect on the plate.

[0045] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the embodiments disclosed above are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
