[0001] This utility model relates to the field of vacuum structures, and in particular to a vacuum structure for a multi-layer laminator. Background Technology

[0002] Solar photovoltaic laminators, as one of the important pieces of equipment for producing solar cell modules, are usually composed of four major systems: heating system, vacuum system, pneumatic system, and control system. Due to the large footprint and low efficiency of traditional laminators, new multi-layer laminators have emerged.

[0003] The new multi-layer laminator features a compact internal structure and precise component fitting. However, the traditional laminator vacuum system is no longer suitable for the new multi-layer laminator in terms of piping layout or diameter. Therefore, designing a completely new multi-layer laminator vacuum system is a problem that technicians urgently need to solve. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a vacuum structure for a multi-layer laminator, aiming to improve the problem that the vacuum structure in the prior art is not suitable for new multi-layer laminators and that the vacuum structure for multi-layer laminators has low practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-layer laminator vacuum structure, comprising a laminator body, laminator components uniformly and fixedly connected to the front and rear sides of the laminator body, heating plates fixedly connected to opposite sides of each laminator component, lower vacuum connecting pipes fixedly connected to the left and right sides of each laminator component, an upper vacuum connecting pipe fixedly connected to the middle of each laminator component, and a vacuum assembly provided on the upper part of the laminator body for evacuating the multi-layer laminator.

An upper vacuum tube is fixedly connected to the right side of the main vacuum tube, and an upper vacuum valve is fixedly connected to the right side of the middle part of the main vacuum tube. A lower vacuum main tube is fixedly connected to the left side of the main vacuum tube, and a lower vacuum valve is fixedly connected to the left side of the middle part of the main vacuum tube. Both ends of the lower vacuum main tube are fixedly connected to lower vacuum tubes.

[0008] As a further description of the above technical solution:

[0009] The upper part of the heating plate has a groove, and the groove has evenly distributed central holes.

[0010] As a further description of the above technical solution:

[0011] The heating plate is fixedly connected to a vacuum connection fixing block on the side away from the heating plate.

[0012] As a further description of the above technical solution:

[0013] The upper vacuum connecting pipe is connected to the heating plate through the central hole, and the lower vacuum connecting pipe is connected to the heating plate through the central hole.

[0014] As a further description of the above technical solution:

[0015] The vacuum pump unit is connected to the main vacuum pipe.

[0016] As a further description of the above technical solution:

[0017] Both the upper vacuum connecting pipe and the lower vacuum connecting pipe are telescopic pipes, and both the upper vacuum connecting pipe and the lower vacuum connecting pipe pass through the vacuum connecting fixing block.

[0018] This utility model has the following beneficial effects:

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Referring to Figures 1-3, one embodiment of this utility model provides a vacuum structure for a multi-layer laminator, including a laminator body 1. Laminator components 14 are uniformly fixedly connected to the front and rear sides of the laminator body 1. Heating plates 2 are fixedly connected to opposite sides of each laminator component 14. Lower vacuum connecting pipes 13 are fixedly connected to the left and right sides of each laminator component 14. An upper vacuum connecting pipe 11 is fixedly connected to the middle of each laminator component 14. A groove 3 is formed on the upper part of the heating plate 2, and central holes 4 are uniformly formed inside the groove 3. The upper vacuum connecting pipe 11 is connected to the heating plate 2 through the central holes 4, and the lower vacuum connecting pipe 13 is connected to the heating plate 2 through the central holes 4. The laminator body 1 is connected to a vacuum assembly on its upper part, which is used to evacuate the multi-layer laminator. The vacuum assembly includes a main vacuum tube 6, which is fixedly connected to the upper middle part of the laminator body 1. An upper vacuum tube 7 is fixedly connected to the right side of the main vacuum tube 6. An upper vacuum valve 8 is fixedly connected to the right side of the middle part of the main vacuum tube 6. A lower vacuum main tube 9 is fixedly connected to the left side of the main vacuum tube 6. A lower vacuum valve 10 is fixedly connected to the left side of the middle part of the main vacuum tube 6. Lower vacuum tubes 12 are fixedly connected to both ends of the lower vacuum main tube 9. A vacuum connection fixing block 5 is fixedly connected to the side of the heating plate 2 away from the heating plate. The vacuum pump group is connected to the main vacuum tube 6.

[0027] By connecting the vacuum pump unit to the main vacuum pipe 6, the system can flexibly control different vacuum pumping pipes according to actual needs. When vacuum pumping is required for the upper vacuum connecting pipe 11, the upper vacuum system is started by controlling the opening of the upper vacuum valve 8. When vacuum pumping is required for the lower vacuum connecting pipe 13, the lower vacuum system is started by controlling the opening of the lower vacuum valve 10. Through this precise control method, the independence of the two vacuum systems in the vacuum structure of the multi-layer laminator is realized, so that each lamination operation can be customized according to the needs of different layers, which greatly improves the flexibility and practicality of the entire system.

[0028] Both the upper vacuum connecting pipe 11 and the lower vacuum connecting pipe 13 are telescopic pipes, and both the upper vacuum connecting pipe 11 and the lower vacuum connecting pipe 13 pass through the vacuum connecting fixing block 5.

[0029] By adopting a telescopic tube design, the upper vacuum connecting tube 11 and the lower vacuum connecting tube 13 achieve telescopic functionality, which allows the tube length to be flexibly adjusted according to different lamination requirements during equipment operation. This ensures that the equipment can accurately follow and complete the predetermined actions when performing each layer opening and lamination operation, greatly improving the accuracy and efficiency of operation.

[0030] Working principle: By connecting the vacuum pump unit to the main vacuum pipe 6, when the upper vacuum connection pipe 11 is needed for vacuum evacuation, the upper vacuum valve 8 is opened to start the upper vacuum system. When the lower vacuum connection pipe 13 is needed for vacuum evacuation, the lower vacuum valve 10 is opened to start the lower vacuum system. This realizes that the two vacuum systems of the multi-layer laminator vacuum structure are independent of each other, which improves the practicality of the multi-layer laminator vacuum structure.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
