Description

Technical Field

[0001] The utility model relates to the technical field of solar photovoltaic module manufacturing, in particular to a device for cleaning sundries on the backplane before lamination of photovoltaic modules. Background Technique

[0002] During the lamination process of solar photovoltaic module manufacturing, when the solar photovoltaic module enters the laminator, foreign objects on the front and back surfaces will also be brought into the machine, resulting in the production of defective products. Since the existing laminator is a fully automatic laminator, there is no personnel to check, and there is no mechanism for cleaning foreign objects, resulting in foreign objects on the back surface being easily brought into the lamination, reducing the lamination quality. Therefore, we propose a device for cleaning sundries on the backplane before lamination of photovoltaic modules to solve the above problems. Content of the Utility Model

[0003] The purpose of the utility model is to solve the above-mentioned disadvantages and propose a device for cleaning sundries on the backplane before lamination of photovoltaic modules.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A device for cleaning sundries on the backplane before lamination of photovoltaic modules, including a laminating machine body for laminating photovoltaic modules, and an elastic scraper for cleaning sundries on the backplane. An inlet is opened on one side of the laminating machine body. Two support plates are fixedly connected to one side of the laminating machine body. A conveying mechanism for feeding the backplane is arranged between the two support plates. A placing seat is fixedly connected to one side of the laminating machine body. A box body is fixedly connected to one side of the placing seat. A disassembly, installation and replacement mechanism is arranged among the placing seat, the box body and the elastic scraper.

[0006] Specifically, the elastic scraper is made of EVA material.

[0007] Specifically, the conveying mechanism includes a conveying motor fixedly connected to the front side of the front support plate, and two conveying rollers rotatably connected between the two support plates. The output shaft of the conveying motor is fixedly connected to the front end of the corresponding conveying roller. The same conveyor belt is drivingly connected to the two conveying rollers.

[0008] Specifically, the height of the support plate is higher than that of the conveyor belt, and the height of the elastic scraper is lower than that of the conveyor belt.

[0009] Specifically, the disassembly and replacement mechanism includes two threaded rods rotatably connected between the box body and the placing seat, and a rotating shaft rotatably connected to one side of the box body. One end of the rotating shaft is fixedly connected with a driving gear, and driven gears are fixedly sleeved on the outer sides of the two threaded rods. The driving gear meshes with the two driven gears. A moving seat is threadedly sleeved on the outer sides of the two threaded rods. Two or more inserting rods are fixedly connected to one side of the moving seat. A plurality of inserting holes are formed in one side of the elastic scraper, and the plurality of inserting rods are respectively movably clamped in the corresponding inserting holes.

[0010] Specifically, a placing groove is formed in one side of the placing seat, and the elastic scraper is slidably sleeved in the placing groove.

[0011] Specifically, a hand wheel is fixedly connected to one end of the rotating shaft, and the moving seat is slidably sleeved in the box body.

[0012] Specifically, a plurality of sliding holes are formed in one side of the placing seat, and the plurality of inserting rods are respectively slidably sleeved in the corresponding sliding holes.

[0013] In the present utility model, for the debris cleaning device for the front backplane of a photovoltaic module before lamination, the front backplane to be laminated is placed on the top of the conveyor belt. The conveying motor drives the operation of the conveying rollers and the conveyor belt, and then the front backplane can be sent into the laminating machine body from the feeding port to the left. Before entering, since the elastic scraper made of EVA material is lower than the heights of the conveyor belt and the front backplane, when feeding, the front backplane will push the elastic scraper to the left, causing the elastic scraper to tilt to the left, so that the right side of the elastic scraper can always abut against the top of the front backplane, thereby automatically cleaning the foreign matters on the top of the front backplane. Moreover, the EVA material has advantages in terms of elasticity, flexibility, glossiness, etc. compared with the PE material, so that the elastic scraper will not cause scratches, displacement, etc. to the front backplane, ensuring the quality of the lamination of the photovoltaic module.

[0014] In the present utility model, for the debris cleaning device for the front backplane of a photovoltaic module before lamination, due to long-term use, foreign matters are easily attached to the right side of the elastic scraper, and in case of damage, the elastic scraper needs to be disassembled, cleaned and replaced. At this time, the rotating shaft and the driving gear are rotated through the hand wheel, and the driving gear drives the synchronous rotation of the two driven gears and the threaded rods. The two threaded rods drive the moving seat to move to the right, and the moving seat drives the plurality of inserting rods to move synchronously to the right and disengage from the inserting holes, thus no longer limiting and fixing the elastic scraper. At this time, the elastic scraper can be disassembled from the placing seat for cleaning and replacement. After cleaning, the elastic scraper is inserted into the placing groove of the placing seat to play the role of limiting and positioning, so that the inserting rods are aligned with the inserting holes. Then the hand wheel is rotated in the reverse direction, so that the moving seat and the plurality of inserting rods move to the left and are clamped in the inserting holes. Through the support of the plurality of inserting rods for the elastic scraper, the elastic scraper can be stably supported and fixed, improving the stability of the installation.

[0015] The structure of the utility model is reasonably designed. The elastic scraper made of EVA material can automatically clean the foreign matters on the top of the front backplane, ensure the lamination quality, and the elastic scraper will not cause scratches or displacement on the front backplane. At the same time, it is beneficial to disassemble and assemble the elastic scraper, which is conducive to cleaning and replacing the elastic scraper in the later stage, and improves the use effect.

Detailed Description of the Preferred Embodiment

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Referring to Figures 1-4 , a device for cleaning sundries on the front backplane before lamination of a photovoltaic module includes a lamination machine body 1 for laminating a photovoltaic module, and an elastic scraper 9 for cleaning sundries on the front backplane. A feed inlet 5 is provided on one side of the lamination machine body 1. Two support plates 2 are fixedly connected to one side of the lamination machine body 1. A conveying mechanism for feeding the front backplane is arranged between the two support plates 2. A placing seat 7 is fixedly connected to one side of the lamination machine body 1. A box body 8 is fixedly connected to one side of the placing seat 7. A disassembly, assembly and replacement mechanism is arranged among the placing seat 7, the box body 8 and the elastic scraper 9.

[0023] Furthermore, the elastic squeegee 9 is made of EVA material, and the EVA material has advantages over PE material in terms of elasticity, flexibility, glossiness, etc. As a result, the elastic squeegee 9 will not cause scratches or displacements on the front backplane, ensuring the quality of the lamination of the photovoltaic module.

[0024] Furthermore, the conveying mechanism includes a conveying motor 4 fixedly connected to the front side of the support plate 2 at the front side, and two conveying rollers 3 rotatably connected between the two support plates 2. The output shaft of the conveying motor 4 is fixedly connected to the front end of the corresponding conveying roller 3. The same conveyor belt 6 is drivingly connected to the two conveying rollers 3. The support plate 2 is higher than the height of the conveyor belt 6, and the elastic squeegee 9 is lower than the height of the conveyor belt 6. By driving the conveying roller 3 and the conveyor belt 6 to operate through the conveying motor 4, the front backplane can be fed into the lamination body 1 from the feeding port 5 to the left. Before entering, since the elastic squeegee 9 made of EVA material is lower than the heights of the conveyor belt 6 and the front backplane, when feeding, the front backplane will push the elastic squeegee 9 to the left, causing the elastic squeegee 9 to tilt to the left, so that the right side of the elastic squeegee 9 can always abut against the top of the front backplane, and thus the foreign matters on the top of the front backplane can be automatically cleaned.

[0025] Furthermore, the disassembly and replacement mechanism includes two threaded rods 13 rotatably connected between the box body 8 and the placing seat 7 and a rotating shaft 16 rotatably connected to one side of the box body 8. One end of the rotating shaft 16 is fixedly connected with a driving gear 15. Driven gears 14 are fixedly sleeved on the outer sides of the two threaded rods 13. The driving gear 15 meshes with the two driven gears 14. A moving seat 11 is threadedly sleeved on the outer sides of the two threaded rods 13. Two or more inserting rods 10 are fixedly connected to one side of the moving seat 11. A plurality of inserting holes 12 are formed in one side of the elastic squeegee 9. The plurality of inserting rods 10 are respectively movably clamped in the corresponding inserting holes 12. An inserting groove 18 is formed in one side of the placing seat 7. The elastic squeegee 9 is slidably sleeved in the inserting groove 18. Rotate the rotating shaft 16 and the driving gear 15. The driving gear 15 drives the two driven gears 14 and the threaded rods 13 to rotate synchronously. The two threaded rods 13 drive the moving seat 11 to move to the right. The moving seat 11 drives the plurality of inserting rods 10 to move to the right synchronously and disengage from the inserting holes 12, thus no longer limiting and fixing the elastic squeegee 9. At this time, the elastic squeegee 9 can be disassembled from the placing seat 7 for cleaning and replacement. After cleaning, insert the elastic squeegee 9 into the inserting groove 18 of the placing seat 7 to achieve the purpose of limiting and positioning, so that the inserting rods 10 are aligned with the inserting holes 12. Then rotate the hand wheel 17 in the reverse direction, so that the moving seat 11 and the plurality of inserting rods 10 move to the left and are clamped in the inserting holes 12. Through the support of the plurality of inserting rods 10 for the elastic squeegee 9, the elastic squeegee 9 can be stably supported and fixed, improving the stability of installation.

[0026] Furthermore, one end of the rotating shaft 16 is fixedly connected to a handwheel 17, the movable seat 11 is slidably mounted in the box body 8, and a plurality of sliding holes are opened on one side of the insertion seat 7, and a plurality of insertion rods 10 are respectively slidably mounted in the corresponding sliding holes, so as to facilitate the rotation of the rotating shaft 16. At the same time, the insertion rods 10 and the movable seat 11 can be guided to make their movement more stable.

[0027] In the utility model, when in use, the front back panel to be laminated is placed on the top of the conveyor belt 6, and the conveying motor 4 drives the conveying roller 3 and the conveyor belt 6 to run, so that the front back panel can be fed to the left from the feeding port 5 into the laminating machine body 1. Before entering, because the elastic scraper 9 made of EVA material is lower than the height of the conveyor belt 6 and the front back panel, during feeding, the front back panel will push the elastic scraper 9 to the left, so that the elastic scraper 9 tilts to the left, so that the right side of the elastic scraper 9 can always abut against the top of the front back panel, so that foreign matter on the top of the front back panel can be automatically cleaned. In addition, EVA material has the advantages of elasticity, flexibility, glossiness, etc. compared with PE, so that the elastic scraper 9 will not cause scratches, displacement, etc. on the front back panel, thereby ensuring the quality of the lamination of photovoltaic modules. Due to long-term use, the right side of the elastic scraper 9 is prone to adhesion of debris, and in the case of damage, it is necessary to The elastic scraper 9 is disassembled, assembled, cleaned and replaced. At this time, the rotating shaft 16 and the active gear 15 are rotated by the hand wheel 17. The active gear 15 drives the two driven gears 14 and the threaded rod 13 to rotate synchronously. The two threaded rods 13 drive the moving seat 11 to move right. The moving seat 11 drives the multiple plug rods 10 to move right synchronously and disengage from the insertion hole 12, and then the elastic scraper 9 is not limited and fixed. At this time, the elastic scraper 9 can be removed from the insertion seat 7 for cleaning and replacement. When the cleaning is completed, the elastic scraper 9 is inserted into the insertion groove 18 of the insertion seat 7 to achieve the purpose of limiting positioning, so that the plug rod 10 is aligned with the insertion hole 12, and then the hand wheel 17 is rotated in the opposite direction, so that the moving seat 11 and the multiple plug rods 10 move left and are clamped in the insertion hole 12. The support of the elastic scraper 9 by the multiple plug rods 10 can stably support and fix the elastic scraper 9, thereby improving the stability of the installation.
