Description

Technical Field

[0001] The utility model belongs to the technical field of secondary trimming of photovoltaic components, in particular to a secondary trimming device of a photovoltaic component. Background Art

[0002] After lamination, the glue residue around the solar cell modules and their glass products must be removed, which is commonly known as the trimming process. In order to prevent hidden cracks at the corners of the modules during trimming, the existing process generally uses two trimmings. The first trimming is to trim the four peripheral main sections of the module, leaving an area of ​​50 to 80 mm on both sides of the corner, and then the second trimming is used to trim the overflow glue in the area of ​​50 to 80 mm on both sides of the corner.

[0003] In the prior art, Chinese patent publication number CN218428495U discloses a photovoltaic module scraping type secondary trimming module and a trimming machine, wherein the secondary trimming module includes a first trimming blade and a second trimming blade. Although the scheme can realize the secondary trimming of the four corners of the photovoltaic module, there are still the following two problems:

[0004] (1) In order to remove the waste material remaining on the trimming blade, an air blowing nozzle aimed at the trimming blade is provided above the end position of the trimming position. Although the air blowing nozzle can remove the waste material, it is necessary to provide a supporting device related to the air blowing. On the one hand, the related supporting device will occupy a certain space. On the other hand, the air blowing to remove the residual glue will result in incomplete removal.

[0005] (2) The first trimming blade and the second trimming blade are both driven by cylinders during trimming. The cylinder speed is slow and the stroke is single, resulting in low production efficiency.

[0006] Therefore, it is necessary to provide a secondary trimming device for a photovoltaic module to solve the above technical problems. Utility Model Content

During trimming, the X drive component and the Y drive component are both servo motors, and the servo motor drive has high production efficiency;

[0021] (3) Before or during trimming, the first and second straightening wheels are used to straighten the sides of the photovoltaic modules in real time. When the servo motor drives the trimming, it can ensure that the trimming is complete and no burrs appear;

[0043] In order to ensure that the first trimming blade 21 and the second trimming blade 31 can be stably aligned on the side of the photovoltaic component during trimming, a first alignment component 27 is arranged side by side with the first trimming blade 21 in the X direction and is used to align one side of the corner of the photovoltaic component at the lower end of the second support plate 25, and a second alignment component 37 is arranged side by side with the second trimming blade 31 in the Y direction and is used to align the other side of the corner of the photovoltaic component at the lower end of the fourth support plate 35.

[0045] In order to prevent waste materials after trimming from remaining on the first trimming blade 21 and the second trimming blade 31, in this embodiment, a collision assembly 4 is provided on the second support plate 25 of the first trimming module 2. In other embodiments, the collision module 4 may be provided on the second trimming module 3, which is not limited here. The collision assembly 4 includes a fixed block 41 fixed on the second support plate 25 and a protruding part 42 protruding from the surface of the fixed block 41 and facing the third support plate 33. When the first trimming module 2 and the second trimming module 3 complete trimming and reach the trimming end position, the first trimming blade 21 and the second trimming blade 31 move closer to each other, and at the same time, the protruding part 42 of the collision assembly 4 will collide with the third support plate 33 of the second trimming module 3, so that the first trimming module 2 and the second trimming module 3 collide and vibrate with each other, causing waste materials on the first trimming blade 21 and the second trimming blade 31 to fall off. On the one hand, this method of removing waste materials is simple and efficient, and the waste materials on the first trimming blade 21 and the second trimming blade 31 can be completely removed without residue, thereby ensuring the accuracy of the next trimming; on the other hand, the collision assembly 4 is simple in structure and occupies very little space.

[0047] In other embodiments, the structure of the protruding part 42 can be set according to actual conditions, as long as the protruding part 42 can hit the third support plate 33 when the first trimming module 2 and the second trimming module 3 complete trimming and reach the trimming end position, so as to achieve the effect of waste materials on the first trimming blade 21 and the second trimming blade 31 falling off. Therefore, the structure of the protruding part 42 is not limited here.

[0048] The working process of the secondary trimming device 100 of the photovoltaic module of the present scheme is as follows: in the initial state, the first trimming module 2 and the second trimming module 3 move to positions away from each other. After the photovoltaic module is delivered to the position, the first driving member 24 of the first trimming module 2 and the second driving member 34 of the second trimming module 3 extend to respectively move the second support plate 25 and the fourth support plate 35 inward at the same time, so that the first trimming blade 21 and the second trimming blade 31 contact the two side edges of the photovoltaic module corner, and at the same time, the first straightening wheel 272 and the second straightening wheel 372 contact the side edge of the photovoltaic module to straighten the photovoltaic module, and the X driving assembly 22 and the Y driving assembly 32 respectively drive the first trimming blade 21 and the second trimming blade 31 to move along the side edge of the photovoltaic module to the corner at the same time, so as to remove the residual The remaining materials are cut off, and when the first trimming module 2 and the second trimming module 3 complete trimming and reach the trimming end position, the first trimming blade 21 and the second trimming blade 31 move close to each other at the trimming end position, and when the first trimming module 2 and the second trimming module 3 are about to reach the trimming end position, the collision component 4 on the first trimming component 2 will collide with the second trimming module 3, so that the waste on the first trimming blade 21 and the second trimming blade 31 falls off and directly falls into the waste receiving box 5 below, completing the trimming, and the first driving member 24 of the first trimming module 2 and the second driving member 34 of the second trimming module 3 retract respectively to move the second support plate 25 and the fourth support plate 35 outward at the same time, and the first trimming module 2 and the second trimming module 3 move to positions away from each other, waiting for the next trimming.

[0049] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
