Description

Technical Field

[0001] This utility model relates to the field of laminating technology, and more specifically to a solar cell module laminating machine. Background Technology

[0002] Solar cell modules are generally composed of solar panels, glass, and encapsulant film. The laminator includes an upper heating chamber, a lower heating plate, a transmission system, and a vacuum system. The solar cell module is fed into the lamination position by the high-temperature cloth of the transmission system. The upper heating chamber is closed, and the shape of the silicone pad inside the upper heating chamber is changed by the vacuum change to achieve the lamination of the solar cell module. The solar panel is fixed on the encapsulant film.

[0003] However, after lamination is completed, when the upper heating box is raised by the lifting mechanism, the silicone pad and the adhesive film of the solar cell module will stick together, affecting normal operation. Manual handling is inefficient.

[0004] Therefore, providing a high-efficiency solar cell module laminator is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a solar cell module laminator to avoid the silicone pad and adhesive film sticking together during the lamination process.

The high-temperature cloth of the transmission system is surrounded on the lower heating plate. The laminator also includes a release film conveying device and a release film wound thereon, with the release film surrounding the upper heating box.

[0008] By adopting the above technical solutions, the beneficial effects of this utility model are as follows:

[0009] The release film transfer device supports and transfers the release film surrounding the upper heating box. When the lamination is completed and the upper heating box is raised, the release film and the adhesive film are separated due to their non-adhesive properties, thus avoiding the adhesion between the silicone pad and the adhesive film and ensuring efficient operation.

[0010] Furthermore, the release film conveying device includes two servo motors and two release film conveying assemblies symmetrically mounted on the front and rear sides of the frame. Each release film conveying assembly includes an air shaft, a film-wrapping support roller, a calculation control roller, a floating roller, a flattening roller, and a pressure roller group, which are sequentially mounted on the frame. The output shaft of the servo motor is fixedly connected to the air shaft. The two servo motors rotate in the same direction. The release film roll is mounted on any of the air shafts. The release film extension end of the release film roll is sequentially wound around the film-wrapping support roller, the calculation control roller, the floating roller, the flattening roller, and the pressure roller group of the release film conveying assembly closest to it, as well as the pressure roller group, the flattening roller, the floating roller, the calculation control roller, and the film-wrapping support roller of the other release film conveying assembly, and finally fixedly connected to the other air shaft.

[0011] Furthermore, it also includes a controller, on which a release film transport length sensor is installed, the release film transport length sensor is electrically connected to the controller, and the controller is electrically connected to the servo motor.

[0012] Furthermore, the flattening roller is a curved roller or a medium-high roller.

[0020] 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.

[0021] like Figure 1-4 As shown in the figure, this utility model discloses a solar cell module laminator, including a frame 1 and an upper heating box 2, a lower heating plate 3, a transmission system 4, and a vacuum system mounted on it. The upper heating box 2 and the lower heating plate 3 are distributed vertically, and the upper heating box 2 is mounted on the frame 1 via a lifting mechanism. The high-temperature cloth 41 of the transmission system 4 surrounds the lower heating plate 3. It also includes a release film transport device 5 and a release film 61 wound on it, which surrounds the upper heating box 2. The release film transport device 5 supports and transports the release film 61 surrounding the upper heating box 2. When the lamination is completed and the upper heating box 2 is raised, the release film 61 and the adhesive film separate due to their non-adhesive properties, avoiding adhesion between the silicone pad and the adhesive film and ensuring efficient operation.

[0022] Specifically, the release film conveying device 5 includes two servo motors and two release film conveying assemblies 51 symmetrically mounted on the front and rear sides of the frame 1. Each release film conveying assembly 51 includes an air expansion shaft 511, a film-wrapping support roller 512, a calculation and control roller 513, a floating roller 514, a flattening roller 515, and a pressure roller group 516, which are sequentially mounted on the frame 1. The output shaft of the servo motor is fixedly connected to the air expansion shaft 511; the two servo motors rotate in the same direction; the release film... The roll 6 is mounted on any of the air expansion shafts 511. The extended end of the release film 61 of the release film roll 6 is sequentially wound around the film support roller 512, calculation and control roller 513, floating roller 514, flattening roller 515, pressure roller group 516 of the release film transfer assembly 51 and the pressure roller group 516, flattening roller 515, floating roller 514, calculation and control roller 513, and film support roller 512 of another release film transfer assembly 51, and finally fixedly connected to another air expansion shaft 511.

[0023] Understandably, the film-wrapping support roller 512, calculation and control roller 513, floating roller 514, flattening roller 515 and pressure roller group 516 can be selected or omitted according to requirements, and the positions of each roller are not fixed and can be adjusted according to requirements and space.

[0024] Among them, the floating roller 514 is made to move by means of counterweight, cylinder, etc., so that the release film 61 runs stably when the speed changes; the flattening roller 515 is a curved roller or a medium-high roller, which flattens the release film 61 and prevents the release film 61 from wrinkling during the transmission process; the pressure roller group 516 presses the release film 61 tightly, so that the release film 61 has independent upper and lower tension with the pressure roller as the dividing line, so that the calculation and control roller 513 can calculate more accurately and move more precisely. The movement of the pressure roller can be achieved by cylinder or hydraulic cylinder, but not limited to these two driving methods.

[0025] Of course, the servo motor can control the release film 61 and the high-temperature cloth 41 to achieve synchronous transmission.

[0026] Specifically, it also includes a controller. A release film transport length sensor is installed on the control roller 513. The release film transport length sensor is electrically connected to the controller, and the controller is electrically connected to the servo motor. In this embodiment, the release film transport length sensor is a tension sensor or an angle sensor. Of course, any sensor that can directly or indirectly calculate the transport length of the release film 61 is acceptable.

[0027] Understandably, it also includes a feeding platform 7 and a discharging platform 8, with the feeding platform 7, frame 1, and discharging platform 8 arranged sequentially from front to back. The feeding platform 7 and discharging platform 8 include, but are not limited to, fixed conveyor type and lifting type, as long as they can meet the transmission requirements.

[0028] To further optimize the technical solution of this utility model, a lifting device 9 is also included. The lifting device 9 is straddling both sides of the frame 1 to facilitate the transport of the release film roll 6 to the position of the air expansion shaft 511 for installation. Of course, other auxiliary feeding methods can also be used.

[0029] The working process of this utility model:

[0030] 1) The release film roll 6 is installed onto an air shaft 511 by the lifting equipment 9, and then the extended end of the release film 61 is sequentially wound around the film support roller 512, calculation and control roller 513, floating roller 514, flattening roller 515, pressure roller group 516 of the release film transfer assembly 51 and the pressure roller group 516, flattening roller 515, floating roller 514, calculation and control roller 513, and film support roller 512 of another release film transfer assembly 51, and finally fixedly connected to another air shaft 511.

[0031] 2) The solar cell module 10 is conveyed into the laminator host by the feeding platform 7. The high temperature cloth 41 of the transmission system 4 conveys the solar cell module 10 into the cavity. Then the upper heating box 2 is closed and lamination begins. After lamination is completed, the upper heating box 2 is raised. Due to the non-stick properties of the release film 61, it separates from the solar cell module 10. Finally, the solar cell module 10 flows out to the discharge platform 8 for cooling and waiting for subsequent processes.
