[0001] The utility model relates to the technical field of photovoltaic module lamination, in particular to a fully automatic lamination device for solar photovoltaic modules. Background Technique

[0002] The lamination device for photovoltaic modules is the core equipment in the production process of photovoltaic modules. Its main function is to press glass, EVA (ethylene-vinyl acetate copolymer), battery strings, EVA, and the backplane of photovoltaic modules into photovoltaic modules by means of vacuum hot pressing. Its working environment needs to maintain high temperature and vacuum to ensure normal hot pressing treatment.

[0003] During the normal processing, whether it is automatic hot pressing or manual feeding of heat, it is inevitable to open and close the processing chamber to realize the loading and unloading of materials. During this process, the vacuum in the processing chamber will be damaged. When processing again, it is necessary to re-pump the vacuum to ensure smooth progress. However, each vacuum pumping operation during processing is an independent step and cannot be synchronized with the gas step, which will lead to a decrease in work efficiency.

A heating plate is fixed in the hot pressing chamber, a bottom support plate is installed below the hot pressing chamber, a pressure plate is installed above the hot pressing chamber, sealing gates are installed at both ends of the laminator and both ends of the hot pressing chamber, and vacuum pumps are fixed above the loading chamber, the hot pressing chamber and the unloading chamber, and pressure sensors are fixed inside.

[0006] Preferably, a row of driving rotating shafts are rotatably connected in the laminator and are equally spaced. A pair of conveying wheels are fixed on each driving rotating shaft. A driving box is fixed on the outside of the laminator at a position corresponding to the driving rotating shaft, and a driving device for driving the driving rotating shafts to rotate synchronously is fixed in the driving box.

[0007] Preferably, a telescopic cylinder is fixed at the bottom of the hot pressing chamber, and the output end of the telescopic cylinder is fixed at the bottom of the bottom support plate. A hydraulic cylinder is fixed at the upper end of the hot pressing chamber, and the output end of the hydraulic cylinder is fixed at the upper end of the pressure plate.

[0008] Preferably, an adaptation groove is opened on the bottom support plate, and the position of the adaptation groove is aligned with the position of the conveying wheels.

[0009] Preferably, the sealing gate includes a fixing plate and a gate plate. The fixing plate is fixed inside the laminator. A gate opening is provided at the middle position of the fixing plate.

A threaded rod is fixed to the output end of the driving motor, and the bottom of the threaded rod is threadedly connected inside the gate plate.

[0010] Preferably, an observation window and a controller are installed outside the laminator. The observation window and the controller correspond to the feeding chamber, the hot pressing chamber, and the discharging chamber one by one.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: The inside of the laminator is divided into a feeding chamber, a hot pressing chamber, and a discharging chamber, which can minimize the damage to the internal vacuum of the hot pressing chamber.

[0019] A row of driving rotating shafts 11 are rotatably connected in the laminator 1 and are equally spaced. A pair of conveying wheels 12 are fixed on each driving rotating shaft 11. A driving box 13 is fixed outside the laminator 1 at a position corresponding to the driving rotating shaft 11. A driving device for driving the driving rotating shafts 11 to rotate synchronously is fixed in the driving box 13. A telescopic cylinder 81 is fixed at the bottom of the hot pressing cavity 3, and the output end of the telescopic cylinder 81 is fixed at the bottom of the bottom support plate 8.

An adapting groove 82 is formed on the bottom support plate 8, and the position of the adapting groove 82 is aligned with the position of the conveying wheels 12.

[0020] The sealing gate 5 includes a fixing plate 51 and a gate plate 53. The fixing plate 51 is fixed in the laminator 1. A gate opening 52 is formed in the middle of the fixing plate 51.

Use the driving equipment in the driving box 13 to drive the driving rotating shaft 11 and the conveying wheel 12 to rotate, so that the photovoltaic modules can enter the hot pressing chamber 3 for hot pressing, and finally flow out from the discharging chamber 4. During the hot pressing process, use the heating plate 31 to heat the hot pressing chamber 3 to a specified temperature, and use the drive of the telescopic cylinder 81 to make the bottom support plate 8 move upward to lift the photovoltaic modules.
