Technical Field

[0001] This utility model relates to the field of photovoltaic module production technology, and in particular to a photovoltaic module glass bonding device. Background Technology

[0002] A photovoltaic (PV) module is a device that connects a number of individual cells in series and parallel and then seals them into a whole, enabling it to convert solar energy into electrical energy. During the production process, a glass sealing device is used to encapsulate the photovoltaic cells with glass, protecting the photovoltaic cells and ensuring the long-term stability, weather resistance, and high conversion efficiency of the PV module.

[0003] In the existing photovoltaic module production process, most production lines adopt continuous conveying and automated processing. After passing through multiple processing stages, photovoltaic cells need to be accurately transferred to the glass bonding unit for encapsulation. During the conveying process, due to equipment vibration, uneven conveyor belt speed, or other mechanical factors, the cells may shift. This shift can cause the photovoltaic cells and glass sheets to fail to align accurately, thus affecting the encapsulation quality. Utility Model Content

[0004] To address the problem in the prior art that photovoltaic cells may shift during transport, resulting in inaccurate alignment between the photovoltaic cells and the glass sheet, thus affecting the packaging quality, this invention proposes a photovoltaic module glass bonding device.

A first telescopic device is provided between the square rods and the clamping plate. The bottom end of the first telescopic device is hinged to the square rod, and the piston rod end of the first telescopic device is hinged to the clamping plate.

[0008] Preferably, the bracket is provided with an adjustment mechanism, which includes two sets of U-shaped guide rails, each set including multiple U-shaped guide rails spaced apart from left to right. Multiple square rods are slidably disposed in the multiple U-shaped guide rails. Multiple vertically open adjustment holes are opened on the U-shaped guide rails. The end of the square rod away from the clamping plate is opened with a vertically open mounting hole. The mounting hole can correspond vertically to any one of the adjustment holes.

[0018] 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.

[0019] Example 1: A photovoltaic module glass bonding device, such as Figure 1-2 As shown, the system includes a conveying mechanism 1 for conveying photovoltaic cells. Specifically, the conveying mechanism 1 includes multiple supports 11 spaced apart front to back. The supports 11 are I-shaped, and a fixed rod 12 extending in the left-right direction is fixedly provided at the top of the support 11. Supports 13 are fixedly provided at both ends of the fixed rod 12. A rotating shaft 14 is rotatably passed through multiple supports 13 located in the same front-back direction. One end of the rotating shaft 14 is provided with a drive motor to drive the rotating shaft 14 to rotate. For those skilled in the art, the drive motor is a well-known technology and is not shown in the figure, so it will not be described in detail. Multiple rollers 15 are fixedly sleeved on the rotating shaft 14. The rollers 15 are located in the supports 13. Conveyor belts 16 are driven on two rollers 15 located in the same left-right direction. Multiple conveyor belts 16 convey the photovoltaic cells together.

[0020] The conveying mechanism 1 is equipped with a positioning mechanism 2, which is used to position the photovoltaic cell so that the glass sheet can be accurately attached to the photovoltaic cell. Specifically, the positioning mechanism 2 includes two square rods 21 mounted on the support 11. The square rods 21 are located below the conveyor belt 16. The opposite ends of the two square rods 21 extend to the front and rear sides of the conveying mechanism 1. The opposite ends of the two square rods 21 are hinged to upward-extending clamping plates 22. The top of the clamping plates 22 is located above the conveyor belt 16. A first telescopic device 23 is provided between the square rods 21 and the clamping plates 22. The first telescopic device 23 is an electric telescopic rod. For those skilled in the art, the first telescopic device 23 is well known technology and will not be described in detail. The bottom end of the first telescopic device 23 is hinged to the square rods 21, and the piston rod end of the first telescopic device 23 is hinged to the clamping plates 22. The first telescopic device 23 can clamp and position the photovoltaic cell between the two clamping plates by controlling the rotation of the clamping plates 22, thereby achieving the positioning of the photovoltaic cell.

[0021] Multiple square rods 21 and clamping plates 22 are provided, with the multiple square rods 21 and clamping plates 22 spaced apart on the left and right. The first telescopic device 23 is provided on the square rod 21 and clamping plate 22 located in the middle. The multiple clamping plates 22 are jointly fixed with the first connecting rod 24, so that the multiple clamping plates 22 located on both sides can rotate together with the clamping plate 22 located in the middle. This not only improves the positioning accuracy, but also distributes the clamping force evenly to multiple positions of the photovoltaic cell, avoiding workpiece deformation or damage caused by uneven force.

[0022] The bracket 11 is equipped with an adjustment mechanism 3, which includes two sets of U-shaped guide rails 31, one at the front and one at the back. Each set includes multiple U-shaped guide rails 31 spaced apart on the left and right. Multiple square rods 21 are slidably disposed within the multiple U-shaped guide rails 31. Multiple vertically open adjustment holes 32 are provided on the U-shaped guide rails 31. The end of the square rod 21 away from the clamping plate 22 is provided with a vertically open mounting hole 33. The mounting hole 33 can correspond vertically to any one of the adjustment holes 32. A bolt 34 is inserted into the mounting hole 33 and its corresponding adjustment hole 32. The bolt 34 is used to fix the square rod 21 on the U-shaped guide rail 31. By adjusting the corresponding position of the mounting hole 33 and the different adjustment holes 32 in the front and back directions, the distance between the two square rods 21 can be adjusted, thereby adjusting the distance between the two clamping plates 22. The spacing of the adjustment holes 32 can be customized according to the specifications of the photovoltaic cells to accommodate photovoltaic cells of the appropriate specifications.

[0023] A fixing plate 4 is fixed between the right ends of the two supports 11 located in the middle. A second telescopic device 5 extending upward is fixed on the fixing plate 4. A baffle 6 is fixed at the top of the second telescopic device 5. The second telescopic device 5 can drive the baffle 6 to move upward to above the conveyor belt 16 to intercept and position the photovoltaic cells. After positioning is completed and the conveyor belt 16 is closed, the baffle 6 can also be driven to move downward to below the conveyor belt 16 to avoid affecting the glass bonding of the photovoltaic cells.

[0024] Example 2, as Figure 3 As shown, the difference between this embodiment and Embodiment 1 is that the U-shaped guide rail 31 has a sliding groove 35 extending in the front-back direction and open at both ends. The sliding groove 35 corresponds vertically to the mounting hole 33. Bolts 34 are inserted in both the sliding groove 35 and the mounting hole 33. The bolts 34 are used to fix the square rod 21 on the U-shaped guide rail 31. By adjusting the position of the mounting hole 33 and the sliding groove 35 in the front-back direction, the distance between the two square rods 21 can be adjusted, thereby adjusting the distance between the two clamping plates 22. Compared with Embodiment 2, the mounting hole 33 can be adjusted at any position of the sliding groove 35, so that the two clamping plates 22 can be used for photovoltaic cells of any width.

[0025] A second connecting rod 36 is fixed between two adjacent square rods 21. The second connecting rod 36 can synchronize multiple square rods 21 in the front-back direction when adjusting the distance between the two clamping plates 22, so as to facilitate the rapid adjustment of the position of multiple square rods 21.

[0026] Working principle: During the photovoltaic module glass bonding process, the conveying mechanism 1 transports the photovoltaic cells to the right via the conveyor belt 16. At this time, the baffle 6 at the end of the piston rod of the second telescopic device 5 is located above the conveyor belt 16, intercepting and positioning the photovoltaic cells in the left and right directions. When the right end of the photovoltaic cell contacts the baffle 6, the first telescopic device 23 is driven to retract. The piston rod of the first telescopic device 23 drives the clamping plate 22 to rotate towards the center until the two corresponding clamping plates 22 are parallel to each other, thereby clamping and positioning the photovoltaic cells. Then, the conveyor belt 16 is closed, and the first telescopic device 23 is driven to extend and the second telescopic device 5 is driven to retract, unfolding the clamping plate 22 to both sides and retracting the baffle 6 below the conveyor belt 16, thereby avoiding collision between the glass sheet and the clamping plate 22 or the baffle when the glass sheet is attached to the photovoltaic cell from above. After the glass bonding is completed, the conveyor belt 16 is restarted to carry out the next photovoltaic module glass bonding.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
