Abstract
Description
Technical Field
[0001] The utility model relates to the field of solar cells, and specifically designs a high-precision solar cell component module positioning device. Background Art
[0002] In the development process of existing solar cell circuit products, single solar cells are generally welded into solar cell modules, and the series connection direction of the solar cell modules is fixed by using low-viscosity tape. The solar cell modules are transferred by holding the low-viscosity tape at both ends of the solar cell modules. The tape is usually positioned by visually observing the surface of the solar cell substrate, and the single-string solar cell modules are manually placed on the surface of the solar cell substrate in turn to paste the solar cell modules.
[0003] The above-mentioned solar cell module pasting method has certain defects. The two ends of the hand-held tape are used for transfer. During the transfer process, the solar cell module is prone to deformation and shaking due to its low rigidity, which is not conducive to the reliability of the connection link of the solar cell module; the parallel gap between the solar cell modules cannot be effectively maintained by manually pasting the single string of solar cell modules on the board in sequence. For the solar cell module composed of multiple strings, the single string of solar cells adopts the visual board positioning method, and the parallel gap between the solar cell strings cannot be effectively controlled. In addition, the cumulative error of the pasting of the solar cell string is large, resulting in the problem of poor pasting accuracy of the solar cell module on the board. It is urgent to design a universal, high-precision solar cell module positioning device. Utility Model Content
[0004] The utility model aims to overcome the defects of the existing solar cell assembly pasting process that the solar cell assembly is not fixed, the gap error between solar cell strings in parallel is large, and the module pasting precision is poor.

[0016] Technical effects of the utility model:

After the solar cell assembly module is placed in position, the vacuum chamber 5 surface exhaust interface switch is turned on to fix the position of the solar cell assembly module, ensuring the high position accuracy of the solar cell assembly module before transfer.
[0018] (2) After the position of the solar cell module is fixed, the transfer of the solar cell module is achieved through the electrostatically adsorbed solar cell module transfer film 7, which controls the string-parallel connection accuracy within the solar cell module to a limited extent and reduces the damage to the solar cell interconnection sheet caused by the shaking of the solar cell string.

DETAILED DESCRIPTION
[0024] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] like Figures 1 to 4 As shown, the utility model provides a high-precision solar cell module positioning device, which mainly includes a solar cell module positioning panel 4, a vacuum chamber 5 and a solar cell module transfer film 7. The solar cell module positioning panel 4 is machined, and the solar cell module is positioned and fixed through the limit strips and air suction holes on its surface. After the solar cell module is positioned and fixed, the transfer of the solar cell module is achieved through the machined solar cell module transfer film 7.
[0026] In order to achieve the positioning of solar cell modules, Figure 1 As shown, the solar cell module positioning panel 4 is provided with a solar cell module parallel gap limiting strip 2, which can ensure the consistency of the parallel gaps between the solar cell modules. At the same time, in order to ensure the accuracy of the position of the solar module, the position of the solar cell module is limited by the solar cell module position limiting strip 3. The solar cell module parallel gap limiting strip 2 and the solar cell module position limiting strip 3 are formed by mechanical processing, and their dimensional accuracy is better than ±0.05mm.
[0027] After the solar cell assembly is placed on the solar cell assembly module positioning panel 4, the position of the solar cell assembly is fine-tuned until the solar cell assembly is completely positioned.
[0028] In order to fix the position of the solar cell module, Figure 2 As shown, the side wall of the vacuum chamber 5 is provided with an exhaust connector 6, which is connected to an external vacuum pump device to realize vacuum suction inside the vacuum chamber 5. In order to prevent the vibration of the external vacuum pump from being transmitted to the vacuum chamber 5 and affecting the sealing of the vacuum environment, Figure 4 As shown, a vacuum sealing pad 9 is also provided between the vacuum cavity 5 and the solar cell module positioning panel 4. After the solar cell module is placed in place, the surface of the solar cell module positioning panel 4 is provided with a solar cell module air intake hole 1, the diameter of the solar cell module air intake hole 1 is a through hole of about 1 mm, the solar cell module air intake hole 1 is arranged in an array, and the area of the air intake hole array region is slightly smaller than the area of the solar cell. When the solar cell module covers the air intake holes provided on the surface of the solar cell module positioning panel 4, the gas inside the vacuum cavity 5 is continuously extracted, and a vacuum environment is formed in the vacuum cavity 5. The solar cell module is adsorbed and fixed on the surface of the solar cell module positioning panel 4 by the pressure difference.
[0029] In order to realize the transfer of solar cell module, such as Figure 3 As shown, the solar cell module transfer film 7 has adsorption transfer capability, and is usually an electrostatic adsorption film with a thickness of 0.1 mm. When the position of the solar cell module is fixed, the solar cell module transfer film 7 is pasted on the surface of the solar cell module module, and each solar cell module is pasted to form a whole. In order to achieve close adsorption between the solar cell module transfer film 7 and the solar cell, a positioning panel limit block notch 8 is provided on the surface of the solar cell module transfer film 7 to avoid interference with the protruding parts of the solar cell module parallel gap limit strip 2 and the solar cell module position limit strip 3 on the surface of the solar cell module positioning panel 4, so as to achieve close adsorption between the solar cell module transfer film 7 and the solar cell, and ensure the transfer accuracy of the solar cell module module.
[0030] The working process of this utility model:
[0031] Step 1: Determine the length and number of solar cell modules, which should not exceed the total size of the solar cell module positioning panel 4;
[0032] Step 2: Place the solar cell assembly on the surface of the solar cell assembly module positioning panel 4, and fine-tune the position of the solar cell assembly until the solar cell assembly is fully positioned;
[0033] Step 3: Open the vacuum joint 6 to start vacuuming. The vacuum joint 6 continuously extracts the gas in the vacuum chamber 5, and a vacuum environment is formed in the vacuum chamber 5. The solar cell module is adsorbed and fixed on the surface of the solar cell module positioning panel 4 by the pressure difference.
[0034] Step 4: Hold the solar cell module transfer film 7 and tightly adsorb the solar cell module through the electrostatic adsorption effect. After the solar cell module transfer film 7 and the solar cell module are completely fixed, close the exhaust joint 6 and transfer the solar cell module by holding the solar cell module transfer film 7.
[0035] In summary, the utility model provides a solar cell module transfer device, which can realize the integrated transfer of modules composed of multiple solar cell modules through the combination of a solar cell module positioning panel 4, a vacuum cavity 5, and a solar cell module module transfer film 7. The positioning accuracy between solar cell modules is greatly improved through tooling, and the damage to solar cell interconnection sheets caused by the shaking of solar cell strings is reduced.
