Description

Technical Field

[0001] This invention relates to the field of photovoltaic panel and module manufacturing technology, and specifically to a residual adhesive cleaning device for photovoltaic panel and module manufacturing. Background Technology

[0002] A solar photovoltaic (PV) panel is a power generation device that produces direct current (DC) electricity when exposed to sunlight. It consists of solid-state photovoltaic cells made almost entirely of semiconductor materials. Simple PV cells can power watches and computers, while more complex PV systems can provide lighting for homes, traffic lights, and surveillance systems, and can be connected to the power grid. During the production of solar PV panels, excess adhesive may adhere to the surface, requiring cleaning equipment to remove it.

[0003] In the prior art, such as the patent document with announcement number CN218424276U, a residual adhesive cleaning device for solar photovoltaic panel production is disclosed. This solution uses a screw to rotate and drive a moving seat to move, and the moving seat drives a scraper to move. The scraper moves to perform preliminary cleaning of the adhesive on the surface of the photovoltaic panel.

[0004] However, in practical applications, after the first application of adhesive, adhesive will adhere to the surface of the scraper. If it is not cleaned in time, it will affect the cleaning effect on the subsequent solar photovoltaic panels. In order to improve the adhesive application effect, the scraper tip is usually set to be tilted at a certain angle. Therefore, manual cleaning is prone to injury and has low safety. Summary of the Invention

[0005] The purpose of this invention is to provide a residual adhesive cleaning device for photovoltaic panel module production, solving the following technical problems:

[0006] After the first application of adhesive by the scraper, adhesive residue will adhere to the surface of the scraper. If it is not cleaned in time, it will affect the cleaning effect on the subsequent solar photovoltaic panels.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Example 1

[0044] Please see Figures 1-2 As shown, the present invention is a residual adhesive cleaning device for photovoltaic panel module production, including a workbench 1, a scraper 4 on the workbench 1, and a scraper end 401 at one end of the scraper 4 facing the workbench 1; specifically, the scraper end 401 is set with a conical structure to facilitate the removal of residual adhesive from the surface of the photovoltaic panel.

[0045] The workbench 1 is also equipped with a first drive unit, which is used to drive the scraper 4 to reciprocate along the length of the workbench 1 to scrape the adhesive on the photovoltaic panel. It can be understood that by placing the photovoltaic panel to be de-adhesive on the surface of the workbench 1 and driving the scraper 4 along the length of the workbench 1 through the first drive unit, the photovoltaic panel can be scraped.

[0046] The workbench 1 is symmetrically equipped with a scraper adhesive removal mechanism 7 on both sides to remove the adhesive adhering to the surface of the scraper tip 401. It can be explained that after one scraping operation, the scraper 4 moves to the beginning or end of the length direction of the workbench 1 and stops. At this time, the adhesive adhering to the surface of the scraper tip 401 can be scraped off by the scraper adhesive removal mechanism 7 to avoid affecting the adhesive removal effect of the subsequent photovoltaic panels. It can also prevent the adhesive on the surface of the scraper tip 401 from re-adhering to the next set of photovoltaic panels. In this embodiment, there is no need for manual cleaning of the adhesive on the scraper tip 401, achieving an automated cleaning effect and higher safety.

[0047] Example 2

[0048] Based on Example 1, please refer to Figure 1 , Figure 4 and Figure 5 The first drive unit includes a drive housing 3 mounted on the workbench 1. A first screw 308 is rotatably mounted in the drive housing 3. The first screw 308 is fixed to the output end of a first motor 301 fixed on the outside of the drive housing 3. A first nut 307 is screwed onto the first screw 308. The first nut 307 is fixed to a scraper mounting bracket 407 via a fixing rod. A scraper 4 is rotatably mounted on the side of the scraper mounting bracket 407 facing the workbench 1. It should be noted that when cleaning residual adhesive from the photovoltaic panel, the first motor 301 is started to drive the first screw 308 to rotate. As the first nut 307 moves on the first screw 308, it drives the scraper mounting bracket 407 to move. The scraper mounting bracket 407 simultaneously drives the scraper 4 and the scraper end 401 to move, thereby achieving the effect of removing adhesive.

[0049] As a further embodiment, drive cylinders 6 are symmetrically fixed on both sides of the workbench 1. The drive end of the drive cylinder 6 is fixed to the drive housing 3 through the mounting bracket 601. It can be understood that when scraping glue, the drive housing 3 is raised and lowered by the drive cylinder 6, thereby adjusting the height of the scraper 4 and the scraper end 401, so as to remove glue from photovoltaic panels of different thicknesses.

[0050] It should be noted that the drive cylinder 6 can also be replaced by an electric cylinder or a hydraulic cylinder, etc., and this embodiment does not limit this.

[0051] Please see Figure 2 and Figure 6The scraper adhesive removal mechanism 7 includes support plates 701 symmetrically arranged on both sides of the workbench 1. Scraper seats 706 are symmetrically slidably arranged on the support plates 701. An inclined surface 707 for sliding contact with the two sides of the scraper end 401 is provided on the side of the two sets of scraper seats 706 that are close to each other. The two support plates 701 are fixed by a connecting frame 606, which is connected to a second drive unit that drives the scraper to reciprocate along the width of the workbench 1. It should be noted that after the photovoltaic panel is coated with adhesive once, the scraper end 401 moves to the position corresponding to the two scraper seats 706. Then, the second drive unit drives the support plates 701 to move toward the scraper end 401 so that the inclined surfaces 707 of the two sets of scraper seats 706 slide and contact with the two sides of the scraper end 401 respectively. After the support plates 701 move to the end of the scraper 4 and reset, the scraper end 401 can be removed with adhesive once.

[0052] In this embodiment, please refer to Figure 1 and Figure 2 The second drive unit includes a support frame 602 fixedly arranged on one side of the workbench 1. A second screw 603 is rotatably arranged on the support frame 602. The second screw 603 is fixed to the output end of a second motor 605 fixedly arranged at the end of the support frame 602. A second nut 604 is screwed onto the second screw 603. The second nut 604 is fixed to the connecting frame 606 by a push rod. Specifically, when cleaning the adhesive on the scraper end 401, the second motor 605 is started to drive the second screw 603 to rotate. During the movement of the second nut 604 on the second screw 603, the push rod can push the connecting frame 606 to move along the width direction of the workbench 1, thereby driving the support plate 701 to move.

[0053] For further details, please refer to Figure 6 Two sets of guide rods 704 are symmetrically fixed at the ends of the two scraper seats 706 that are far apart. The guide rods 704 are slidably connected to the supports 703 fixed on the support plate 701. The guide rods 704 are provided with a first spring 705. One end of the first spring 705 is fixed to the scraper seat 706 and the other end is fixed to the support 703. Specifically, in order to improve the glue removal effect on the scraper end 401, the first spring 705 pushes the two scraper seats 706 closer to each other, thereby improving the tightness of the inclined surface 707 when it is in contact with the two sides of the scraper end 401, which facilitates glue removal.

[0054] After the scraper 706 removes adhesive once, some adhesive material will fall into the gap between the two sets of scraper 706. In this embodiment, an L-shaped bracket 607 is provided on one side of the support plate 701. One end of the L-shaped bracket 607 is fixed to the worktable 1, and the other end is provided with a tapered end 608. The support plate 701 has a through groove 702 for material discharge. It can be explained that when the scraper 706 scrapes the material, the second drive unit drives the support plate 701 to move towards the L-shaped bracket 607. The tapered end 608 can be embedded between the two sets of scraper 706, thereby pushing the two scraper 706 on both sides to move away from each other, realizing separation, so that the adhesive material located between the two falls and is discharged through the through groove 702. At this time, the first spring 705 contracts to generate elastic force, so as to drive the scraper 706 to reset.

[0055] Please see Figure 1 and Figure 5 A number of adsorption holes 102 are equally spaced on the workbench 1. Each row of adsorption holes 102 is connected to an adsorption box 202 fixedly arranged at the bottom of the workbench 1. A negative pressure pump 2 is fixedly arranged at the bottom of the workbench 1. The output end of the negative pressure pump 2 is connected to the main adsorption pipe 201. Each adsorption box 202 is connected to the main adsorption pipe 201 through a secondary adsorption pipe 203. It can be explained that when the photovoltaic panel to be degummed is placed on the workbench 1 and the negative pressure pump 2 is started, the negative pressure pump 2 generates negative pressure in the adsorption box 202 through the main adsorption pipe 201 and the secondary adsorption pipe 203 to fix the photovoltaic panel on the workbench 1 and prevent the photovoltaic panel from shaking during the degumming process.

[0056] In this embodiment, during the reciprocating motion of the scraper end 401 along the length of the worktable 1, in order to achieve the effect of reciprocating scraping, please refer to... Figure 8 It is necessary to adjust the tilt angle of scraper 4 relative to the horizontal direction based on the direction of its movement. Specifically:

[0057] Please see Figure 4 and Figure 9A cylindrical body 402 is fixedly mounted on the scraper 4. Several sets of strip-shaped slots 403 are arranged in a circumferential array on the inner wall of the cylindrical body 402. Positioning seats 406 are symmetrically fixed on both sides of the scraper fixing frame 407 facing the worktable 1. A support shaft 404 is rotatably mounted between the two positioning seats 406. The cylindrical body 402 is sleeved on the support shaft 404. Several sets of strip-shaped slots 405, corresponding to and slidingly engaging with the strip-shaped slots 403, are fixedly arranged in a circumferential array on the support shaft 404. A first gear 409 and a second gear 410 are symmetrically fixed at both ends of the support shaft 404. A first rack 506 for meshing with the first gear 409 is provided on one side of the first gear 409. The first rack 506 is connected to a first lifting part that drives it to move vertically. The second gear 409... A second rack 510 is provided on one side for meshing with it. The second rack 510 is connected to a second lifting part that drives it to move up and down in the vertical direction. The first rack 506 and the second rack 510 are arranged in parallel and offset. It can be explained that when the scraper 4 is located at the starting end on one side of the workbench 1, the scraper 4 is in a vertical state. When the scraper 4 is driven to move towards the tail end and remove glue from the photovoltaic panel, the first lifting part drives the first rack 506 to move towards the workbench 1. The first rack 506 drives the support shaft 404 to rotate by meshing with the first gear 409. The support shaft 404 drives the cylinder 402 and the scraper 4 to rotate by a corresponding angle through the strip-shaped card seat 405 and the strip-shaped card slot 403, so as to remove the excess glue on the photovoltaic panel.

[0058] When the scraper 4 moves to the tail section of the worktable 1, the scraper 4 returns to the vertical position. When the scraper 4 is driven to move towards the starting end, the second rack 510 is driven to move towards the worktable 1 through the second lifting part. The second rack 510 drives the support shaft 404 to rotate by meshing with the second gear 410, thereby adjusting the scraper 4 to rotate in the opposite direction by the corresponding angle.

[0059] In this embodiment, the scraper 4 can adjust its tilt angle in real time during one reciprocating motion to improve the adhesive removal effect.

[0060] Please refer to Figure 4The scraper fixing bracket 407 has symmetrically fixed baffles 408 at both ends away from the worktable 1. A drive rod 507 is slidably mounted on one side of the baffle 408 in the vertical direction. One end of the drive rod 507 is fixed to a rack, and the other end has a rotatable guide wheel 509. A second spring 508 is mounted on the drive rod 507, with one end fixed to the fixed end of the rack and the other end fixed to the baffle 408. The first lifting part includes a first guide frame 302 for rolling contact with the guide wheel 509, and the second lifting part includes a second guide frame 304 for rolling contact with the guide wheel 509. The unit also includes an adjustment part for adjusting the separation or contact between the guide wheels 509 and the guide frames. It should be noted that when the scraper 4 is lifted from the worktable 1... When the scraper 4 moves from the beginning to the end, the guide wheel 509 on the first lifting part is driven by the adjustment part to abut against the first guide frame 302, while the guide wheel 509 on the second lifting part is separated from the second guide frame 304. Correspondingly, when the scraper 4 moves from the end to the beginning, the guide wheel 509 on the first lifting part is separated from the first guide frame 302, and the guide wheel 509 on the second lifting part abuts against the second guide frame 304. When the guide wheel 509 is in abutting state with the guide frame, as the scraper 4 moves horizontally, the guide wheel 509 drives the rack to move towards the worktable 1 through the drive rod 507 under the action of the guide frame, thereby driving the gear to deflect. When the guide wheel 509 is separated from the guide frame, the second spring 508 can drive it to reset.

[0061] In this embodiment, please refer to Figure 1 Both the first guide frame 302 and the second guide frame 304 include a first guide plate 305 and a second guide plate 306 arranged parallel to each other in the vertical direction. The first guide plate 305 is located on the side closer to the worktable 1, and the length of the first guide plate 305 is less than the length of the second guide plate 306. The two ends of the first guide plate 305 and the second guide plate 306 are fixed by the inclined plate 303. Specifically, when the guide wheel 509 is separated from the guide frame, the top end of the guide wheel 509 is flush with the upper surface of the second guide plate 306. When the drive scraper 4 moves in the horizontal direction, the guide wheel 509 first abuts against the inclined plate 303 and then moves along the first guide plate 305.

[0062] In addition, please see Figure 3The adjustment unit includes an adjustment frame 104 disposed on one side of the workbench 1. The adjustment frame 104 has a first guide groove 105 and a second guide groove 106 arranged parallel to each other. The first guide groove 105 is located on the side facing the workbench 1, and its length is less than the length of the second guide groove 106. The two sides of the first guide groove 105 are connected to the second guide groove 106 via a first inclined groove 107 and a second inclined groove 108, respectively. The first guide groove 105 and the second guide groove 106 are connected to the first inclined groove 107 and the second inclined groove 108, respectively. Two inclined grooves 108 form a closed circulation groove, in which a limiting rod 502 is slidably arranged. The two ends of the support shaft 404 are respectively rotatably connected to the limiting seat 5, and the limiting rod 502 is fixed to the limiting seat 5. It should be understood that when the guide wheel 509 on the side of the first lifting part abuts against the first guide frame 302, the limiting rod 502 slides along the first guide groove 105. When the guide wheel 509 on the side of the second lifting part abuts against the second guide frame 304, the limiting rod 502 slides along the second guide groove 106.

[0063] For details, please refer to Figure 1 and Figure 4 An L-shaped support 501 is slidably mounted on the limiting rod 502. An adjusting rod 505 is fixedly mounted on the L-shaped support 501 facing the worktable 1. A slide groove 101 is provided on one side of the worktable 1, and a slide block 103 is slidably mounted in the slide groove 101. An adjusting plate 503, fixed to the slide block 103, is slidably mounted on the adjusting rod 505. A third spring 504 is also provided on the adjusting rod 505; one end of the third spring 504 is fixed to the L-shaped support 501, and the other end is fixed to the adjusting plate 503. It can be noted that... When the limiting rod 502 slides in the circulation groove, the third spring 504 is always in a stretched state, thus giving the limiting rod 502 a pulling force towards the worktable 1. When the scraper 4 moves from the starting end to the tail end of the worktable 1, the limiting rod 502 is pulled from the second guide groove 106 along the first inclined groove 107 into the first guide groove 105 under the elastic force of the third spring 504. When the scraper 4 moves towards the starting end, it can enter the second guide groove 106 along the second inclined groove 108.

[0064] In addition, please see Figure 7When entering the second guide groove 106 along the second inclined groove 108, in order to prevent the limiting rod 502 from getting stuck in the second inclined groove 108, in this embodiment, a baffle 111 is rotatably arranged at the connection end between the second inclined groove 108 and the second guide groove 106, a limiting groove 110 is opened on the groove wall of the second inclined groove 108, and a torsion spring 112 is provided at the connection end between the baffle 111 and the groove wall of the second inclined groove 108. A buffer groove 109 is also provided at the end of the second guide groove 106, and a reserved groove 113 for the rotation of the baffle 111 is also provided on one side of the second guide groove 106. Specifically, the limiting rod 502... When moving along the second inclined groove 108 into the second guide groove 106, the limiting rod 502 pushes the baffle 111 to rotate toward the reserved groove 113. At this time, the limiting rod 502 continues to move forward into the buffer groove 109. The baffle 111 can be reset under the action of the torsion spring 112 and engage with the limiting groove 110. Then the limiting rod 502 can move along the second guide groove 106 toward the first inclined groove 107 to the initial position. In this embodiment, no other servo drive mechanism is needed to drive the limiting rod 502 to adjust its position, which saves costs and improves the degree of automation.

[0065] Please note that you should refer to [link / reference]. Figure 1 Two sets of guide frames 609 are symmetrically fixed on the workbench 1, and the two ends of the scraper 4 slide and fit with the guide frames 609. Specifically, when the adjustment unit is adjusting, the scraper 4 always moves in the guide frames 609 on both sides to avoid the scraper 4 shifting to one side.

[0066] A residual adhesive cleaning device for photovoltaic panel module production, the cleaning method includes the following steps:

[0067] Place the photovoltaic panel to be degummed on the workbench 1. The negative pressure pump 2 generates negative pressure in the adsorption box 202 through the main adsorption tube 201 and the secondary adsorption tube 203 to fix the photovoltaic panel on the workbench 1.

[0068] The drive cylinder 6 drives the drive housing 3 to rise and fall, adjusting the height of the scraper 4 and the scraper end 401.

[0069] The first motor 301 is started to drive the first screw 308 to rotate. As the first nut 307 moves on the first screw 308, it drives the scraper fixing frame 407 to move. The scraper fixing frame 407 synchronously drives the scraper 4 and the scraper end 401 to move, thus removing the adhesive from the photovoltaic panel.

[0070] After one application of adhesive, the scraper end 401 moves to a position corresponding to the scraper seats 706 on both sides. The second drive unit drives the support plate 701 to move toward the scraper end 401 so that the inclined surfaces 707 of the two sets of scraper seats 706 slide and fit against the two sides of the scraper end 401 respectively. After the support plate 701 moves to the end of the scraper 4, it resets to remove adhesive from the scraper end 401.

[0071] When the drive scraper 4 moves toward the tail end and removes adhesive from the photovoltaic panel, the first lifting part drives the first rack 506 to move toward the worktable 1. The first rack 506 drives the support shaft 404 to rotate by meshing with the first gear 409. The support shaft 404 drives the cylinder 402 and the scraper 4 to rotate by a corresponding angle through the strip-shaped card seat 405 and the strip-shaped card slot 403.

[0072] After the scraper 4 moves to the tail section of the worktable 1, it returns to the vertical position and drives the scraper 4 to move towards the starting end. The second lifting part drives the second rack 510 to move towards the worktable 1. The second rack 510 drives the support shaft 404 to rotate by meshing with the second gear 410, thereby adjusting the scraper 4 to rotate in the opposite direction by the corresponding angle.
