Description

Technical Field

[0001] The invention relates to a device for cleaning debris from thin film processing of an insulating layer of a solar cell assembly. Background Art

[0002] The insulation layer is a crucial component of solar cell modules. The thickness of the insulation layer is 100 to 200 μm, while the thickness of a solar cell is approximately 175 μm. During production and processing, the insulation layer requires laser drilling corresponding to the electrode locations where the solar cell will be mounted. The diameter of the drilling is 2.5 to 5 mm, but there will be residue left after the laser drilling. During the packaging of solar cell modules, if there is residual waste on the insulation layer, it can easily crush the solar cell, affecting the production yield of the solar cell module. Currently, manufacturers mainly rely on manual visual inspection to detect whether there is waste in the insulation layer film. However, manual inspection is not only inefficient but also prone to missed inspections. Summary of the Invention

[0020] like Figures 1 to 3 As shown ( Figure 2 The feeding platform 5 is omitted).

[0021] The cleaning device comprises a frame 1, a feeding platform 5, two groups of scraping and cleaning components 3, two groups of induction components and two groups of pressure roller components 2.

[0022] The frame 1 is an aluminum profile frame, and two groups of scraping and cleaning components 3, two groups of induction components and two groups of pressure roller components 2 are all arranged on the upper side of the frame 1.

[0023] Two groups of pressure roller assemblies 2 are arranged on the left and right sides of the frame 1 in sequence, and the two groups of pressure roller assemblies 2 are arranged at the same horizontal height. Each group of pressure roller assemblies 2 includes a drive motor, an upper pressure roller 21 and a lower pressure roller 22. The upper pressure roller 21 and the lower pressure roller 22 are arranged horizontally in sequence. The front and rear ends of the upper pressure roller 21 and the front and rear ends of the lower pressure roller 22 are respectively supported on the frame 1 through bearings. The side walls of the upper pressure roller 21 are in contact with the side walls of the lower pressure roller 22. The drive motor is fixed to the frame 1 by bolts. The drive motor drives the upper pressure roller 21 and the lower pressure roller 22 to rotate in opposite directions through a belt transmission mechanism (the drive motor and the belt transmission mechanism are both conventional products on the market, not shown in the figure). The two groups of pressure roller assemblies 2 are arranged at intervals in sequence, and the area between the upper pressure roller 21 and the lower pressure roller 22 of all pressure roller assemblies 2 constitutes a scraping channel 23 for the reciprocating movement of the insulating layer film of the solar cell module.

[0024] The two groups of scraping and cleaning components 3 are respectively arranged on both sides of the length direction of the scraping channel 23. The scraping and cleaning components 3 include a scraper 31, a support roller 32, a scraping motor and three driving cylinders 33. The three driving cylinders 33 are fixed to the upper side of the frame 1 through a bracket, and the three driving cylinders 33 are on the upper side of the scraping channel 23. The three driving cylinders 33 are driven synchronously, and the piston rods of the driving cylinders 33 extend downward, and the ends of the piston rods of all the driving cylinders 33 are welded and fixed to the scraper 31. The length direction of the scraper 31 is aligned with the length of the scraping channel 23. 3 is consistent with the width direction, the driving cylinder 33 drives the scraper 31 to move up and down, the support roller 32 is slightly lower than the horizontal height of the scraping channel 23, and the two ends of the support roller 32 are also supported on the frame 1 through bearings. When the scraper 31 moves to its lowest stroke position, the scraped blade contacts the side wall of the support roller 32, and the scraping motor is installed on the frame (the scraping motor is not shown in the figure). The scraping motor drives the support roller 32 to rotate, and the rotation direction and speed of the support roller 32 are consistent with the rotation direction and speed of the lower pressure roller 22 of the pressure roller assembly 2.

[0025] The two groups of sensing components correspond one to one with the two groups of scraping and cleaning components 3. Each group of sensing components is located between the pressure roller component 2 and the corresponding scraping and cleaning component 3. The sensing component includes three photoelectric sensors 41 for detecting the position signals of the insulating layer film of the solar cell component. The photoelectric sensors 41 are aligned with the scraping channel 23.

[0026] Six auxiliary plates 11 are provided on the frame 1 for supporting the insulating layer film of the solar cell module. Auxiliary plates 11 are respectively provided on the adjacent sides of the scraping and cleaning component 3 and the pressure roller component 2. The upper end surface height of the auxiliary plate 11 is consistent with the horizontal height of the scraping channel 23.

[0027] The feeding table 5 is located on the right side of the frame 1. The lower part of the feeding table 5 is a frame structure of aluminum profiles. The upper end face of the feeding table 5 is open. A feeding net 51 is provided on the upper end face of the feeding table 5. The edge of the feeding net 51 is connected with the starting end (right end) of the scraping channel 23.

[0028] The frame 1 is also fixedly mounted with an electrostatic eliminator 6, which is located on the upper side of the starting end of the scraping channel. The air outlet of the electrostatic eliminator 6 is aligned with the starting end of the scraping channel. The electrostatic eliminator 6 can eliminate static electricity in the insulating layer.

[0029] When in use, the insulating film of the solar cell module is first placed on the feeding net 51 of the feeding table 5, and the insulating film is gradually fed into the starting end of the scraping channel 23. The three photoelectric sensors 41 of the sensing component at the right position sense the insulating film before the insulating film enters the scraping channel 23. At the same time, if the three photoelectric sensors 41 of the sensing component at the left position do not sense the insulating film, the sensing component on the right sends a signal to the external control circuit.

[0030] The drive motors of the two sets of pressure roller assemblies 2 are started to rotate forward, and the upper pressure roller 21 and the lower pressure roller 22 rotate synchronously. The upper pressure roller 21 and the lower pressure roller 22 clamp the insulating film and drive the insulating film to move toward the end of the scraping channel 23. During this process, the three drive cylinders 33 of the scraping and cleaning assembly 3 on the right side are started, and the scraper 31 moves downward. The scraper 31 rests on the upper end surface of the insulating film, and the scraper 31 cooperates with the supporting roller 32 to clamp the insulating film. As the insulating film gradually moves, the scraper 31 scrapes off the punched waste on most of the right area of ​​the insulating film.

[0031] The insulating film moves to the left and out of the sensing range of the three photoelectric sensors 41 of the sensing assembly on the right. At the same time, the three photoelectric sensors 41 of the sensing assembly on the left sense the insulating film, and the driving motors of the two sets of pressure roller assemblies 2 are started to reverse, and the upper pressure roller 21 and the lower pressure roller 22 drive the insulating film to move toward the starting end of the scraping channel 23; the three driving cylinders 33 of the scraping and cleaning assembly 3 on the right are started in reverse, and the scraper 31 moves upward, and the scraper 31 separates from the insulating film; during this process, the three driving cylinders 33 of the scraping and cleaning assembly 3 on the left are started, and the scraper 31 rests on the upper end surface of the insulating film, and the scraper 31 scrapes off the punched waste on most of the left area of ​​the insulating film;

[0032] Until the insulating layer film moves to the right and out of the sensing range of the three photoelectric sensors 41 of the sensing component at the right position, and at the same time, the three photoelectric sensors 41 of the sensing component at the left position do not sense the insulating layer film, the driving motors of the two sets of pressure roller assemblies 2 are stopped, and the driving cylinders 33 of the two sets of scraping and cleaning assemblies 3 are controlled, and the scraper 31 moves upward to the maximum stroke. At this time, the insulating layer film completes a complete operation of scraping off the punching waste, and the insulating layer film can be removed to enter the next process.

[0033] The above is only one embodiment of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the principles of the present invention, and these should also be regarded as falling within the scope of protection of the present invention.
