Description

Technical Field

[0001] The utility model belongs to the technical field of processing tooling, and specifically relates to a processing fixture. Background Art

[0002] Perovskite is widely used in the field of solar cells. A perovskite solar cell is a solar cell that uses an organic metal halide semiconductor of the perovskite type as a light-absorbing material, belonging to the third generation of solar cells, also known as a new concept solar cell.

[0003] In the intermediate process of perovskite products, a film is first coated on one side of the perovskite, and then the whole perovskite is cut into multiple small pieces, and finally the perovskite products are removed from the processing fixture. In the prior art, the common loading and unloading method is vacuum adsorption, and the direct contact between the film surface of the perovskite and the suction cup will affect the performance of the product. Therefore, for perovskite products, the vacuum adsorption method cannot be used for material taking, and the clamping method needs to be adopted. However, the traditional fixture cannot separate the small pieces of perovskite after cutting, and there is no gap between adjacent small pieces, so automatic clamping and unloading cannot be realized.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a processing fixture. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a processing fixture, which can solve the problem that there is no gap between the small pieces of perovskite after cutting, resulting in relatively low clamping and unloading efficiency.

[0006] In order to achieve the above purpose, the technical solution provided by a specific embodiment of the utility model is as follows:

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] To enable those skilled in the art to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] It should be noted in advance that this embodiment takes the processing of perovskite sheet products as an example for illustrative elaboration, which does not mean that the processing fixture in this embodiment is only applicable to perovskite products. It can be understood that the processing fixture of the present application is also applicable to other products that need to be clamped for loading and unloading.

[0030] Refer to Figure 1 , the processing fixture in an embodiment of the present utility model includes a bottom plate 1, a plurality of moving plates 2, and a driving member 3. The plurality of moving plates 2 are arranged in a linear array and are all slidably connected to the bottom plate 1. The arrangement direction of the plurality of moving plates 2 is the same as their slidable direction. In this embodiment, a plurality of guide rails are fixedly connected to the bottom plate 1, and the moving plates 2 are slidably connected to the guide rails. The side of the moving plate 2 away from the bottom plate 1 is used to carry and limit the fixing of the workpiece. The driving member 3 can be controlled to drive the plurality of moving plates 2 to slide to a first state (such as Figure 2 ) where they are spaced apart from each other and a second state (such as Figure 3 ) where they are in contact and joined together.

[0031] During operation, the driving member 3 first drives the plurality of moving plates 2 to slide to the second state where they are joined together. Then, the staff places the perovskite product to be processed on the side of the moving plate 2 away from the bottom plate 1, and uses a laser to cut the whole perovskite product into multiple small pieces. After cutting, the driving member 3 drives the plurality of moving plates 2 to slide to the first state where they are spaced apart from each other. At this time, there is a spacing between the multiple small pieces, which is convenient for subsequent processes to unload the products through the clamping jaws.

[0032] In other embodiments, when the plurality of moving plates 2 are in the second state, the moving plates 2 may not be set to be in complete contact. It can be understood that there may also be a certain spacing between the plurality of moving plates 2 in the second state. For example, the spacing between the plurality of moving plates 2 in the second state may be relatively smaller than that in the first state, but it does not affect the carrying and limiting fixing of the workpiece.

[0033] Refer to Figure 2 , a linkage component 4 is provided between adjacent moving plates 2. The driving member 3 drives at least one of the plurality of moving plates 2, so that the plurality of moving plates 2 slide to the first state or the second state under the action of the linkage component 4. In this embodiment, the driving member 3 can be a cylinder.

[0034] Specifically, referring to Figure 4 , the linkage assembly 4 includes a slider 41 provided on one of the adjacent moving plates 2 and a slide bar 42 provided on the other. A chute 411 is formed in the slider 41, and the extending direction of the chute 411 is the same as the slidable direction of the moving plate 2. The slide bar 42 is slidably disposed in the chute 411.

[0035] When the plurality of moving plates 2 are in the first state, the slide bar 42 abuts against the first groove wall of the chute 411 (see Figure 2 ); when the plurality of moving plates 2 are in the second state, the slide bar 42 abuts against the second groove wall of the chute 411 (see Figure 3 ). Wherein, the first groove wall is the groove wall away from the moving plate 2 provided with the corresponding slider 41, the second groove wall is the groove wall adjacent to the moving plate 2 provided with the corresponding slider 41, and the first groove wall and the second groove wall are located at both ends of the chute 411 along the slidable direction of the moving plate 2.

[0036] Therefore, when the driving member 3 drives the moving plate 2 to be in the first state or the second state, the force can be effectively transmitted between the moving plates 2 through the abutting and limiting of the slide bar 42 and the slider 41, so that a linkage displacement is generated between the plurality of moving plates 2.

[0037] In this embodiment, referring to Figure 1 , the bottom plate 1 is provided with a mounting groove 11, and the driving member 3 is fixed in the mounting groove 11 so that the driving member 3 is located between the moving plate 2 and the bottom plate 1. The driving member 3 drives the outermost moving plate 2 to move, so that the plurality of moving plates 2 slide under the action of the linkage assembly 4.

[0038] Wherein, due to the small area of the perovskite product and the limitation of the installation space, the present application sets the cooperation of one driving member 3 and multiple groups of linkage assemblies 4 to complete the switching between the first state and the second state of the moving plate 2. In other embodiments, if the space is not limited, multiple driving members 3 can also be provided to drive the movement of each moving plate 2 respectively, so that the plurality of moving plates 2 are in the first state or the second state.

[0039] Furthermore, referring to Figure 2 and Figure 3 , the processing fixture of this embodiment further includes a fixing plate 5 fixedly connected to the bottom plate 1. The fixing plate 5 is used to limit the maximum movable distance of the plurality of moving plates 2 along their slidable direction. The fixing plate 5 is also connected to the adjacent moving plate 2 through the linkage assembly 4. Therefore, since the fixing plate 5 is fixed, the movable range of the plurality of moving plates 2 can be limited.

[0040] In this embodiment, the fixing plate 5 and the moving plate 2 have exactly the same shape and structure. Therefore, the fixing plate 5 can be used as a moving plate 2 to play a role. It can be understood that in other embodiments, the fixing plate 5 can also be set to other shapes, as long as it can limit the maximum movable distance of the plurality of moving plates 2.

[0041] Referring to Figure 1 and Figure 5 , a first air passage 21 communicating with the adsorption device is provided in the moving plate 2, and a first air hole 22 communicating with the first air passage 21 is provided on the surface of the moving plate 2 away from the bottom plate 1. Therefore, after the perovskite product is placed on the moving plate 2, the perovskite product can be adsorbed and fixed by vacuum through the first air hole 22.

[0042] Furthermore, referring to Figure 5 , a second air passage 23 communicating with the first air passage 21 is further provided in the moving plate 2. The extending directions of the first air passage 21 and the second air passage 23 are perpendicular to each other. A second air hole 24 communicating with the second air passage 23 is further provided on the surface of the moving plate 2 away from the bottom plate 1. The moving plate 2 is provided with at least two adsorption stations for adsorbing and fixing workpieces, and at least two first air holes 22 and at least two second air holes 24 are arranged in cooperation with the adsorption stations.

[0043] In this embodiment, one moving plate 2 is provided with five adsorption stations. In other embodiments, there may also be other numbers of adsorption stations. By providing a plurality of adsorption stations, a plurality of small pieces of perovskite products can be adsorbed and fixed. The cooperation of the first air holes 22 and the second air holes 24 in multiple directions can effectively increase the adsorption area of the perovskite products, so as to ensure that the perovskite products located on the corresponding moving plate 2 will not fall during the movement of the moving plate 2.

[0044] It can be understood that when the moving plate 2 adsorbs and fixes the workpiece, sealing plugs are arranged at the corresponding positions of the first air passage 21 and the second air passage 23, so as to ensure the adsorption effect of vacuum adsorbing the workpiece.

[0045] Referring to Figure 5 , avoiding holes 25 for the feeding gripper to extend into are provided on both sides of each adsorption station of the moving plate 2. Therefore, when the driving member 3 drives the moving plate 2 to move to the first state, the avoiding holes 25 facilitate the gripper to abut against the bottom surface of the workpiece, so as to complete the picking of the workpiece.

[0046] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model.
