Description

Technical Field

[0001] The invention belongs to the field of solar cell processing, and in particular relates to a typesetting and welding integrated machine. Background Art

[0002] Crystalline solar panels are devices that use the photovoltaic effect to convert solar energy into electrical energy. Crystalline solar panels, also known as photovoltaic solar panels, are usually composed of multiple photovoltaic cells that absorb sunlight and convert it into direct current electricity. These panels can be installed on the roof, ground or other appropriate areas of a building for power generation or supply. Photovoltaic solar panels, as an important means of clean energy generation, are increasingly valued and widely used. Globally, governments and companies have invested in photovoltaic power generation projects to reduce dependence on traditional fossil energy, reduce environmental pollution and promote sustainable development.

[0003] During the processing of crystalline solar cells, it is usually necessary to align the busbars and the battery strings before welding. In the prior art, the welding of busbars and battery strings is usually completed in separate processes using multiple devices. For example, the busbars are first cut manually or with a special cutting device, and then the battery strings are arranged in a single row. The busbars are then welded to the battery strings in sections and batches, and finally the battery strings are spliced ​​together. When the busbars and battery strings are welded in the above manner, since the equipment is not integrated, the processes are scattered and the equipment is numerous, making it difficult to use one machine.

[0056] During operation, the battery string transfer table 100 receives the battery string from the previous process and conveys it forward. After conveying it to the bottom of the grasping and correcting mechanism 300, the grasping and correcting mechanism 300 grasps it, and then the CCD camera 200 takes pictures of the battery strings at the first, middle and last positions and sends them to the back-end control end for comparison.

Please refer to Figures 11 to 21 , please refer to the attached Fig.11 The drawing bar welding module 700 includes a tail bus bar feeding mechanism 1 for cutting and feeding the tail bus bar, a tail bus bar welding mechanism 2 for receiving the tail bus bar transferred from the tail bus bar feeding mechanism 1, a tail bus bar transfer mechanism 3 for transferring the tail bus bar on the tail bus bar feeding mechanism 1 to the tail bus bar welding mechanism 2, a middle bus bar feeding and bending mechanism 4 for cutting, feeding and bending the middle bus bar, a middle bus bar welding mechanism 5 for receiving the middle bus bar transferred from the middle bus bar feeding and bending mechanism 4, and a middle bus bar transfer mechanism 3 for transferring the tail bus bar on the tail bus bar feeding mechanism 1 to the tail bus bar welding mechanism 2. A middle bus bar transfer mechanism 6 for transferring the middle bus bar on the bar feeding and bending mechanism 4 to the middle bus bar welding mechanism 5, a head bus bar feeding mechanism 7 for cutting and feeding the head bus bar, a head bus bar welding mechanism 8 for receiving the head bus bar transferred from the head bus bar feeding mechanism 7, a head bus bar transfer mechanism 9 for transferring the head bus bar on the head bus bar feeding mechanism 7 to the head bus bar welding mechanism 8, and a moving track 10 for horizontal movement of the tail bus bar welding mechanism 2, the middle bus bar welding mechanism 5 and the head bus bar welding mechanism 8;

[0063] The tail bus bar welding mechanism 2 is arranged above the tail bus bar feeding mechanism 1, the tail bus bar transfer mechanism 3 is arranged above the tail bus bar welding mechanism 2, the middle bus bar welding mechanism 5 is arranged above the middle bus bar feeding and bending mechanism 4, the middle bus bar transfer mechanism 6 is arranged above the middle bus bar welding mechanism 5, the head bus bar welding mechanism 8 is arranged above the head bus bar feeding mechanism 7, and the head bus bar transfer mechanism 9 is arranged above the head bus bar welding mechanism 8. The tail bus bar welding mechanism 2, the middle bus bar welding mechanism 5 and the head bus bar welding mechanism 8 are all arranged on a movable track 10.

[0064] When working, the tail bus bar feeding mechanism 1 first cuts and feeds the tail bus bar, then the tail bus bar transfer mechanism 3 descends to absorb the tail bus bar, and then lifts up, and then the tail bus bar welding mechanism 2 moves on the moving track 10 to between the tail bus bar feeding mechanism 1 and the tail bus bar transfer mechanism 3, and then the tail bus bar transfer mechanism 3 places the tail bus bar on the tail bus bar welding mechanism 2, and the tail bus bar welding mechanism 2 finally transfers the tail bus bar on the moving track 10 to the tail position of the battery string for welding;

[0065] The working principles of the head bus bar feeding mechanism 7, the head bus bar welding mechanism 8, and the head bus bar transfer mechanism 9 are the same as those of the tail bus bar feeding mechanism 1, the tail bus bar welding mechanism 2, and the tail bus bar transfer mechanism 3, except that the head bus bar is finally moved to the head of the battery string by the head bus bar welding mechanism 8 for welding;

[0066] The middle bus bar is first cut, loaded and bent by the middle bus bar feeding and bending mechanism 4. Compared with the head bus bar and the tail bus bar, the middle bus bar needs to be bent, so the working principle is different. When working, the middle bus bar feeding and bending mechanism 4 cuts, loads and bends the bus bar into the following Fig.15 shape, and then the middle bus bar transfer mechanism 6 descends to adsorb and then lifts up, and then the middle bus bar welding mechanism 5 moves on the moving track 10 to between the middle bus bar feeding and bending mechanism 4 and the middle bus bar transfer mechanism 6, and then the middle bus bar transfer mechanism 6 places the middle bus bar on the middle bus bar welding mechanism 5, and the middle bus bar welding mechanism 5 moves to the middle of the battery string for welding.

[0067] Through the above method, the head bus bar, tail bus bar and middle bus bar can be prepared and transferred to the specified position of the battery string independently at the same time, and then heated and welded after being pressed down by the battery string. The cutting, transfer, positioning and welding of the head, middle and tail bus bars can be completed at one time in an automated manner, thereby improving the welding efficiency of the battery string and the bus bar.

It should be noted that there is an embedding groove 151 on the tail bus bar guide track 15, and the guide column 152 is a conical fiber column structure, which can be inserted into the embedding groove 151 and fixed by magnet adsorption. The upper end cone can be made into different sizes corresponding to the 3\4\5\6mm size requirements. When changing the model, only different guide columns 152 need to be replaced, which is convenient for changing the model to adapt to bus bars of different specifications.

[0071] During operation, the middle bus bar needs to be formed on the middle bus bar feeding and bending mechanism 4 as follows: Fig.15 The shape of the bus bar is then grasped by the middle bus bar transfer mechanism 6, that is, after the middle bus bar roll 31 is unloaded, it is pulled by the middle bus bar unloading device 32 and the middle bus bar pulling device 34, and after being cut by the middle bus bar cutting device 33, it is pulled to the bar placing device 35, attached Fig.15The middle busbars of the first, second, third and fourth sections from left to right are straight at the beginning, and then placed on the first section bar placement module 351, the second section bar placement module 352, the third section bar placement module 353 and the fourth section bar placement module 354, and then through the six groups of pressure strip devices 36, that is, the pressure strip swing arm 362 is driven by the swallow bar cylinder to swing to press the four sections of busbars, and the lifting and bending cylinder 371 of the three groups of lifting and bending devices 37 drives the bending block 372 to lift and bend the busbar, as shown in the attached figure.

[0072] For further information, please refer to the attached Fig.18 The four guide surfaces of the bus bar guide block 39 have different guide widths. The bus bar guide block 39 and the first section bar module 351, the second section bar module 352, the third section bar module 353 and the fourth section bar module 354 are fixed in an interlocking manner, and the four guide surfaces of the bus bar guide module have different widths.
