Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic module manufacturing technology, and in particular relates to a trimming device that can prevent material from sticking to the corners of photovoltaic modules. Background Technology

[0002] In the lamination process of photovoltaic (PV) modules, a vacuum is required to remove air from the module, and the adhesive is heated to bond the cells, glass, and backsheet together. The adhesive melts at high temperatures, and due to vacuum pressure, it extends outwards and solidifies, forming rough edges. Therefore, a step in PV module production requires trimming the laminated modules. The laminated modules are moved to a trimming machine, which removes excess material from the four edges. Existing trimming machines have various structures, all of which move the trimming module from the two sides to the right angle for trimming, and finally leave the module at the right angle. After the trimming module leaves the module, the adhesive's high stickiness leaves residual adhesive at the right angle, affecting the module's quality. Manual secondary removal is inefficient; therefore, automated equipment is needed to thoroughly remove residual adhesive from the right angles of the PV modules.

[0003] Chinese Patent Publication No. CN222450620U discloses an automatic edge trimming device for photovoltaic modules. During operation, a robotic arm moves a base plate, first using a cutting blade to remove excess adhesive around the perimeter of the photovoltaic module. Then, the robotic arm rotates the base plate, positioning the trimming device opposite the corner of the photovoltaic module and moving it to that corner. The corner of the photovoltaic module enters the cutting groove, and then the trimming and cutting cylinder extends first, followed by the trimming and pressing cylinder. Positioning rollers press against the side of the photovoltaic module, causing the trimming blade to abut against the side of the photovoltaic module, and then the trimming process begins. The cutting cylinder retracts, and the trimming cutting cylinder drives the trimming blade to move towards the end of the photovoltaic module corner to complete the trimming on both sides of the corner. Then the trimming clamping air retracts, and the robotic arm drives the base plate to reset. The above scheme is equipped with a cutting device and a trimming device. First, the cutting device trims the side edge, approaching the corner of the photovoltaic module. Then, the trimming device trims the corner of the photovoltaic module. The cutting device and the trimming device complete the cutting and trimming actions in sequence. In addition, the base plate needs to be rotated to change the position of the cutting device and the trimming device. The above scheme is not only complex in structure, but also has low processing efficiency.

[0004] A secondary trimming device for photovoltaic modules, as disclosed in Chinese Patent Application No. 2024206318290, includes a simple collision component. When the first and second trimming modules have completed trimming and reached the trimming end position, the cutting edges of the first and second trimming blades are pressed together. Simultaneously, the protruding part of the collision component impacts the third support plate of the second trimming module, causing the first and second trimming modules to collide and vibrate, resulting in the waste material falling off the first and second trimming blades. However, this solution can only remove residual adhesive on the trimming blades and cannot remove residual adhesive at the right angles of the photovoltaic module.

[0005] Therefore, it is necessary to provide a trimming device that can prevent material from sticking to the corners of photovoltaic modules to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0019] Example 1: Please refer to Figures 1-3 This embodiment describes a trimming device 100 that prevents material from sticking to the corners of photovoltaic modules. It is mounted on a trimming machine (not shown in the figure).

The first trimming module 1 has a first trimming blade 133 at its end, and the second trimming module 2 has a second trimming blade 253 and a collision component 3 at its end. The collision component 3 includes a first cylinder 3. 1. A covering collision member 32, driven by the first cylinder 31, extends and covers the side of the photovoltaic module. After the first trimming module 1 and the second trimming module 2 finish trimming, the first trimming knife 133 moves and abuts against one side of the corner of the photovoltaic module. The first cylinder 31 drives the covering collision member 32 to cover the other side of the corner of the photovoltaic module. The covering collision member 32 moves along the side of the photovoltaic module toward the first trimming knife 133 and hits the first trimming knife 133 to remove the residual glue at the corner of the photovoltaic module.

[0020] The first trimming module 1 includes a first XY axis drive component 11, a first support plate 12 driven by the first XY axis drive component 11 to move along the XY direction, and a first trimming assembly 13 disposed on the first support plate 12.

The second trimming assembly 25 and the collision assembly 3 are arranged side by side. The second trimming assembly 25 includes a fourth cylinder 251 disposed on the third support plate 24, a second mounting bracket 252 driven by the fourth cylinder 251 to move along the X direction, and a second trimming blade 253 is adjustablely disposed on the second mounting bracket 252.

[0022] The first XY axis drive unit 11 and the second XY axis drive unit 21 can drive the first trimming blade 133 and the second trimming blade 253 to move along the XY direction, respectively, which can be adapted to photovoltaic modules of different sizes and improve the versatility of the trimming machine.

[0023] The output shaft of the first cylinder 31 is connected to a third mounting bracket 33, and the position of the covering collision member 32 is adjustable on the third mounting bracket 33. The first cylinder 31 drives the third mounting bracket 33 to move in the X direction and make the covering collision member 32 cover the side of the photovoltaic module. The covering collision member 32 covers the upper surface edge, side, and lower surface edge of the photovoltaic module.

[0024] The first mounting bracket 132, the second mounting bracket 252, and the third mounting bracket 33 have the same structure, and each has a mounting groove at one end. After placing the first trimming knife 133, the second trimming knife 253, or the covering collision member 32 into the mounting groove, a cover plate is placed on the outside and the first trimming knife 133, the second trimming knife 253, or the covering collision member 32 is fixedly installed into the mounting groove with screws. The mounting slot is tilted to allow the first trimming blade 133, the second trimming blade 253, or the covering collision member 32 to be tilted. The tilt angle is set according to the actual situation. Specifically, the first trimming blade 133 cuts the side of the photovoltaic module in the X direction. The first trimming blade 133 is set at an angle to the X direction, which can smoothly remove the residual adhesive on the side of the photovoltaic module in the X direction. The second trimming blade 253 cuts the side of the photovoltaic module in the Y direction. The second trimming blade 253 is set at an angle to the Y direction, which can smoothly remove the residual adhesive on the side of the photovoltaic module in the Y direction. The covering collision member 32 covers the side of the photovoltaic module in the Y direction and moves along the side of the photovoltaic module in the Y direction to contact the first trimming blade 133. The covering collision member 32 is set at an angle to the Y direction, which can smoothly remove the residual adhesive on the corner of the photovoltaic module.

[0025] The first trimming blade 133 and the second trimming blade 253 have the same structure, and are consistent with the structure of the cutting blade in the automatic edge trimming device for photovoltaic modules disclosed in patent announcement number CN222450620U. They can also be consistent with the structure of the cutting blade in the trimming blade assembly disclosed in patent announcement number CN209737671U. The first trimming blade 133 and the second trimming blade 253 are provided with second mounting holes for fixing to the first mounting bracket 132 and the second mounting bracket 252 by screws. The second mounting holes are vertically extending oblong holes to facilitate adjustment of the height of the first trimming blade 133 and the second trimming blade 253. Both sides of the first trimming blade 133 and the second trimming blade 253 are provided with multiple cutting edges. On the one hand, the height of the first trimming blade 133 and the second trimming blade 253 can be adjusted to select different cutting edge positions. On the other hand, the height of the first trimming blade 133 and the second trimming blade 253 can be adjusted to adapt to photovoltaic modules of different thicknesses. Alternatively, the front and back sides of the first trimming blade 133 and the second trimming blade 253 can be adjusted to change different cutting edges for cutting operations. Multiple cutting edges can reduce the number of blade changes, reduce maintenance time, and extend the service life of the first trimming blade 133 and the second trimming blade 253.

[0026] The encasing collision member 32 includes an upper mounting part 321 and a lower encasing collision part 322. The mounting part 321 is provided with a first mounting hole 324 for fixing to the third mounting bracket 33 by screws. The first mounting hole 324 is a vertically extending waist-shaped hole, which facilitates the adjustment of the height of the encasing collision member 32 to adapt to photovoltaic modules of different thicknesses. The encasing collision part 322 is provided with a slot 323 for encasing the side of the photovoltaic module on the side facing the photovoltaic module. The longitudinal section of the slot 323 is conical and the opening angle of the slot 323 is large. On the one hand, the large opening angle of the slot 323 can facilitate the smooth insertion of the side of the photovoltaic module into the slot 323, which can play a guiding role. On the other hand, the longitudinal section of the slot 323 is conical, and photovoltaic modules of different thicknesses will be inserted into different positions of the slot 323, which can adapt to photovoltaic modules of different thicknesses and has good versatility.

[0027] In this embodiment, a detection sensor 4 is installed on the third cylinder 23 of the second trimming module 2 to detect whether the photovoltaic module has been delivered to the correct position. Once the photovoltaic module is delivered to the correct position and the detection sensor 4 detects it, the first trimming module 1 and the second trimming module 2 begin trimming operations. In other embodiments, the detection sensor 4 may be installed on the second support plate 22 of the second trimming module 2, or on the third support plate 24 of the second trimming module 2. This can be configured according to the actual situation and is not limited here.

[0028] Multiple solenoid valves and pressure regulating valves are provided on both the first trimming module 1 and the second trimming module 2. The pressure regulating valves are used to adjust the pressure of the cylinder. These structures are common technical means in the prior art and will not be described in detail here.

[0029] To ensure that the first trimming blade 131 and the second trimming blade 253 can be stably aligned with the side of the photovoltaic module during trimming, in this embodiment, a straightening component 14 is provided on the first support plate 12 of the first trimming module 1. The straightening component 14 and the first trimming component 13 are arranged side by side in the X direction and are used to straighten one side of the corner of the photovoltaic module. The straightening component 14 includes a fifth cylinder 141 arranged on the first support plate 12 and a straightening wheel 142 driven by the fifth cylinder 141 to move in the Y direction. Since the second trimming blade 253 and the collision component 3 are arranged side by side at the end of the second trimming module 2, in order to ensure the stability of the structure and simplify the structure, this embodiment does not provide a straightening component on the second trimming module 2. In other embodiments, a straightening component can be added to the second trimming module 2 according to the actual situation. The specific location of the added straightening component is not limited here.

[0030] When applying the trimming device 100 provided in this solution to prevent material from sticking to the corners of photovoltaic modules, after the photovoltaic module is transported into place and aligned, initially, the first trimming module 1 and the second trimming module 2 are far apart and located on both sides of the corner of the photovoltaic module. After the detection sensor 4 detects that the photovoltaic module is aligned, the fifth cylinder 141 of the alignment component 14 extends to bring the alignment wheel 142 close to the side of the photovoltaic module for further alignment. The first XY axis drive component 11 of the first trimming module 1 drives the first trimming component 1. 3. Approaching one side of the photovoltaic module's corner, the second cylinder 131 drives the first mounting bracket 132 to move along the Y direction, causing the first trimming blade 133 to contact one side of the photovoltaic module's corner for trimming. Simultaneously, the second XY axis drive component 21 of the second trimming module 2 drives the second trimming assembly 25 to approach the other side of the photovoltaic module's corner, and the fourth cylinder 251 drives the second mounting bracket 252 to move along the X direction, causing the second trimming blade 253 to contact the other side of the photovoltaic module's corner. The first XY axis drive component 1 of the first trimming module 1... 1. The first trimming blade 133 moves along the X-direction, and the second XY axis drive component 21 of the second trimming module 2 drives the second trimming blade 253 to move along the Y-direction. Simultaneously, the first trimming blade 133 and the second trimming blade 253 move towards the corner to remove residual adhesive from both sides of the photovoltaic module. After trimming by the first trimming module 1 and the second trimming module 2, the first trimming blade 133 moves and abuts against one side of the photovoltaic module corner. The first cylinder 31 drives the covering collision component 32 to cover the other side of the photovoltaic module corner. The second XY axis drive component... 21. The covering collision component 32 moves along the side of the photovoltaic module towards the first trimming knife 133 and impacts the first trimming knife 133. The second cylinder 131 drives the first trimming knife 133 to retract. At the same time, the first cylinder 31 drives the covering collision component 32 to retract. The covering collision component 32 and the first trimming knife 133 cooperate to remove the residual adhesive at the corner of the photovoltaic module. The residual adhesive falls directly into the waste collection box below (not shown in the figure), completing the trimming. The first trimming module 2 and the second trimming module 3 move to a position away from each other to reset, ready for the next trimming.

[0031] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
