Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic module manufacturing technology, and in particular relates to a tape head clamping mechanism. Background Technology

[0002] During the production of photovoltaic modules, a laminator is needed to press together several layers of materials, including glass, EVA, solar cells, and backsheet. Before lamination, to ensure the installation position of each component of the photovoltaic module, tape is usually applied around the perimeter of the photovoltaic module before it enters the laminator. The tape is applied to the sides of the photovoltaic module and covers the edges of the upper, sides, and lower surfaces. After lamination, the tape used for fixing needs to be removed. This requires first picking up the tape ends and then clamping them to tear them off.

[0003] Regarding the mechanism for removing the tape head, various mechanisms have been designed in the prior art. For example, a flexible lead-wire tape-tearing mechanism disclosed in Chinese Patent Publication No. CN220208902U includes a downward-pressing cylinder fixed to a frame. The output end of the downward-pressing cylinder is connected to a scraper. The upper end of the scraper is equipped with an upper clamping jaw that is raised and lowered by an upper clamping jaw cylinder. The upper clamping jaw cooperates with the scraper to perform a clamping action. The scraper is tilted to scrape off the tape head. After scraping off the tape head, the upper clamping jaw descends, and the upper clamping jaw cooperates with the scraper to perform a clamping action on the tape head, and then the tape is torn off. Another example is the elastic clamping device for tearing tape heads for optical lenses disclosed in Chinese Patent Publication No. CN108044849B. Through a clamping jaw positioning device, a tape head clamping device, and an elastic scraping tape head device, it can be used in tape peeling equipment and monomer filling equipment. In automated production, it can accurately and quickly find and clamp the tape head of the lens mold. However, both of the above solutions have the following problems:

[0004] (1) After the scraper or elastic scraper cuts open the tape head, the upper jaw or clamp needs to clamp the end of the tape, and then the entire structure or device is moved by the linear drive to complete the tape tearing operation. However, during the tape tearing process, the scraper or elastic scraper is always extended and will contact the tape, which will cause the tape to be scraped or cut, thus making it impossible to complete the tape tearing operation smoothly.

[0005] (2) Moreover, the above solutions can only scrape off and hold the tape head in one plane. The tape on the photovoltaic module is wrapped around the edge of the upper surface, the side and the lower surface of the photovoltaic module. Neither of the above two solutions can complete the action of scraping off the tape head and holding it.

[0006] Therefore, it is necessary to provide a tape head clamping mechanism to solve the above-mentioned technical problems. Utility Model Content

[0007] The main purpose of this invention is to provide a tape head clipping mechanism, which solves the problem of cutting the tape during the tape tearing process and enables the tape tearing action to be completed smoothly.

[0008] This utility model achieves the above-mentioned objective through the following technical solution: a tape head shovel clamping mechanism, which includes a first driving member, a mounting plate driven by the first driving member to move, and a shovel clamping module disposed on the mounting plate. The shovel clamping module includes a first jaw disposed on the mounting plate, a second jaw cooperating with the first jaw to perform a clamping action, and a second driving member driving the second jaw to rotate open or close. The first jaw is provided with a shovel blade that can move elastically. The shovel blade is provided with a limiting hole at the end away from the blade edge. The second jaw is provided with a wedge that extends into the limiting hole. When the second driving member drives the second jaw to rotate and close, the wedge extends into the limiting hole, which can retract the shovel blade.

[0009] Furthermore, the first gripper is provided with an installation space for mounting the shovel blade.

[0010] Furthermore, the scraper includes an installation end that mates with the installation space and a scraper end for scraping the tape head.

[0011] Furthermore, a spring is provided on the mounting end, and the other end of the spring is provided on the side wall of the mounting space.

[0012] Furthermore, a bottom cover is provided below the installation space at the installation end. The bottom cover is placed on the bottom of the first gripper and fixed to the first gripper with several screws, thereby covering the blade inside the installation space.

[0013] Furthermore, the bottom surface of the bottom cover, the bottom surface of the first gripper, and the bottom surface of the shovel are flush with each other.

[0014] Furthermore, both the first and second grippers have mutually cooperating serrated structures on the inner side of their gripping ends.

[0015] Furthermore, the first gripper is fixedly mounted on the mounting plate via a first support shaft, and the second gripper is rotatably mounted at the other end of the first support shaft.

[0016] Furthermore, one end of the second gripper is mounted on the mounting base via a second support shaft, and the drive shaft end of the second drive member is connected to the mounting base.

[0017] Compared with the prior art, the beneficial effects of the tape head clamping mechanism of this utility model are as follows:

[0018] (1) The first jaw of the shovel clamp module is provided with a shovel blade that can move horizontally and elastically. The shovel blade is provided with a limit hole at the end away from the blade. The second jaw is provided with a wedge that extends into the limit hole. The wedge is located on the inner side of the second jaw. When the tape head is shoveled up, the second drive unit drives the second jaw to rotate and close. When the wedge extends into the limit hole, it can retract the shovel blade. When the shovel blade retracts, it no longer contacts the tape head. Only the first jaw and the second jaw clamp the tape head and move along the side of the photovoltaic module to perform the tape tearing operation. This can solve the problem that the shovel blade cuts the tape when the first jaw and the second jaw clamp the tape and tear the tape. The tape tearing operation can be completed smoothly.

[0019] (2) The tape head shovel clamping mechanism is provided with a first driving component and a pair of mounting plates driven by the first driving component to move closer or further away from each other. The mounting plates are provided with shovel clamping modules on the same side. When working, the two shovel clamping modules act on the upper and lower surfaces of the photovoltaic module respectively. The shovel clamping modules on the upper and lower sides are arranged opposite each other and simultaneously complete the action of shoveling the tape head on the upper and lower surfaces of the photovoltaic module and clamping the tape head, which makes it easy to tear off the tape on the side of the photovoltaic module.

[0020] (3) The tape head shovel clamping mechanism is provided with a first driving component and a mounting plate that is driven by the first driving component to move. The mounting plate is provided with multiple shovel clamping modules. The multiple shovel clamping modules can shovel multiple tape heads at the same time, so that multiple tapes can be torn off at the same time, which can improve work efficiency.

Detailed Implementation

[0031] Example 1:

[0032] Please refer to Figures 1-6 This embodiment is a tape head shovel clamping mechanism 100, which can simultaneously shovel up and clamp the tape head on the upper and lower surfaces of the photovoltaic module. The tape head shovel clamping mechanism 100 includes a first driving member 10 and a pair of mounting plates 20 driven by the first driving member 10 to move closer or further apart from each other. Shovel clamping modules 30 are respectively arranged opposite each other on the same side of the mounting plates 20. During operation, the two shovel clamping modules 30 act on the upper and lower surfaces of the photovoltaic module. The shovel clamping module 30 includes a first gripper 1 disposed on the mounting plate 20, a second gripper 2 cooperating with the first gripper 1 to perform a clamping action, and a second driving member 3 driving the second gripper 2 to rotate and open or close. The first gripper 1 is provided with a... The scraper 4 is horizontally elastic and has a limiting hole 41 at the end away from the blade. The second gripper 2 is provided with a wedge 21 that extends into the limiting hole 41. The wedge 21 is located inside the second gripper 2. When the tape head is scraped up, the second driving member 3 drives the second gripper 2 to rotate and close. When the wedge 21 extends into the limiting hole 41, the scraper 4 can retract. When the scraper 4 retracts, it no longer contacts the tape head. The tape head is held by the first gripper 1 and the second gripper 2 and moves along the side of the photovoltaic module to tear the tape. This solves the problem of the scraper cutting the tape during the tearing process when the first gripper 1 and the second gripper 2 are holding the tape, making it easier to complete the tape tearing action smoothly.

[0033] In this embodiment, the first driving component 10 is a gripper cylinder. A pair of mounting plates 20 are respectively fixed on the two sliding claws of the gripper cylinder. The gripper cylinder drives the pair of mounting plates 20 to move closer or further apart. A scraper module 30 is provided on the same side of each mounting plate 20. One first driving component 10 can simultaneously drive the upper and lower scraper modules 30 to move to the upper and lower surfaces of the photovoltaic module, which can improve the working cycle and increase production efficiency. During operation, the two opposing mounting plates 20 are located on the upper and lower sides of the photovoltaic module, respectively. At the same time, the scraper module 30 on the upper mounting plate 20 is located on the upper side of the photovoltaic module, and the scraper module 30 on the lower mounting plate 20 is located on the lower side of the photovoltaic module. The upper and lower scraper modules 30 are arranged opposite each other to simultaneously complete the action of scraping and holding the tape head on the upper and lower surfaces of the photovoltaic module, which facilitates tearing off the tape on the side of the photovoltaic module and improves the efficiency of tearing tape.

[0034] The first gripper 1 has a mounting space 11 for mounting a scraper 4. The scraper 4 includes a mounting end 42 that mates with the mounting space 11 and a scraping end 43 for scraping the tape head. A spring 6 is mounted on the mounting end 42, extending horizontally, with the other end of the spring 6 mounted on the side wall of the mounting space 11. When the tape head is scraped up, the second drive unit 3 drives the second gripper 2 to rotate and close, and the wedge 21 extends into the limiting hole 41, causing the scraping end 43 of the scraper 4 to retract to the inside of the first gripper 1. At this time, the spring 6 is compressed. After the tape is torn, when the second drive unit 3 drives the second gripper 2 to rotate and open, and the wedge 21 disengages from the limiting hole 41, the spring 6 extends, causing the scraper 4 to extend to the outside of the first gripper 1, ready for the tape head scraping operation.

[0035] A bottom cover 5 is provided below the installation space 11 at the installation end 42. After the scraper 4 is placed into the installation space 11, the bottom cover 5 is placed on the bottom of the first gripper 1 and fixed to the first gripper 1 with several screws 51, thereby covering the scraper 4 inside the installation space 11. The bottom cover 5 can prevent foreign objects from entering the installation space 11 and can prevent the spring 6 from failing, thus ensuring that the scraper 4 can extend and retract smoothly. The bottom surface of the bottom cover 5, the bottom surface of the first gripper 1, and the bottom surface of the scraper 4 are flush with each other, so that they contact the surface of the photovoltaic module when scraping the adhesive head, so as to complete the adhesive head scraping operation smoothly.

[0036] Both the first gripper 1 and the second gripper 2 have mutually cooperating serrated structures 12 on the inner side of their gripping ends. When the first gripper 1 and the second gripper 2 grip the end of the tape, the serrated structures 12 ensure the stability of the gripping and prevent the tape head from slipping off during gripping. The gripping end of the first gripper 1 is inclined and the opening end is thinner, so that the scraped tape head can smoothly enter the first gripper 1. Moreover, the upper surface of the scraper 4 is lower than the upper surface of the gripping end of the first gripper 1, so that the scraper 4 can retract smoothly.

[0037] The first gripper 1 is fixedly mounted on the mounting plate 20 via the first support shaft 7. The second gripper 2 is rotatably mounted on the other end of the first support shaft 7. One end of the second gripper 2 is mounted on the mounting base 9 via the second support shaft 8. The drive shaft end of the second drive member 3 is connected to the mounting base 9. When the drive shaft end of the second drive member 3 extends, one end of the second gripper 2 swings downward, thereby causing the second gripper 2 to rotate and open around the first support shaft 7. When the drive shaft end of the second drive member 3 retracts, one end of the second gripper 2 swings upward, thereby causing the second gripper 2 to rotate and close around the first support plate 7. The layout shape of the second drive member 3 and the second gripper 2 is ">", which has a folded structure, reducing the space occupied by the shovel clamping mechanism.

[0038] When the tape head shovel clamping mechanism 100 provided in this solution is applied, the driving mechanism (not shown in the figure) drives the tape head shovel clamping mechanism 100 to move to one corner of the photovoltaic module. The two opposing mounting plates 20 are located on the upper and lower sides of the photovoltaic module, respectively. At the same time, the shovel clamping module 30 on the upper mounting plate 20 is located on the upper side of the photovoltaic module, and the shovel clamping module 30 on the lower mounting plate 20 is located on the lower side of the photovoltaic module. The first driving member 10 drives the pair of mounting plates 20 to move closer to each other. The shovel blades 4 of the upper and lower surface shovel clamping modules 30 contact the tape head on the photovoltaic module. The driving mechanism (not shown in the figure) drives the tape head shovel clamping mechanism 100 to move, thereby realizing the action of shoveling the tape head. The shovel blades 4 move from the inside of the photovoltaic module to the edge of the photovoltaic module, thereby shoveling the tape head at the edge of the photovoltaic module. At the same time, the tape head extends into the serrated structure of the first clamping claw 1. After the tape head is shoveled up, when the drive shaft end of the second driving member 3 retracts, the second clamping claw 1... One end of claw 2 swings upward, causing the second claw 2 to rotate and close around the first support plate 7. During the closing of the second claw 2, the wedge 21 extends into the limiting hole 41, causing the scraper end 43 of the scraper 4 to retract to the inside of the first claw 1. At this time, the spring 6 is compressed, and the scraper 4 retracts and no longer contacts the tape head. Only the first claw 1 and the second claw 2 hold the tape head. The first claw 1 and the second claw 2 of the scraper clamp module 30 on the upper and lower surfaces of the photovoltaic module hold the tape head at the same time. The drive mechanism (not shown in the figure) drives the tape head scraper clamp mechanism 100 to move along the side of the photovoltaic module to perform the tape tearing operation. After the tape is torn, when the drive shaft end of the second drive member 3 extends, one end of the second claw 2 swings downward, causing the second claw 2 to rotate and open around the first support shaft 7. At the same time, when the wedge 21 disengages from the limiting hole 41, the spring 6 extends, causing the scraper 4 to extend to the outside of the first claw 1, ready for the second tape head scraping operation.

[0039] Example 2:

[0040] In Embodiment 1, because it is necessary to simultaneously scoop up and clamp the tape head on both the upper and lower surfaces of the photovoltaic module, the tape head scooping and clamping mechanism 100 includes a first driving member 10 and a pair of mounting plates 20 driven by the first driving member 10 to move closer or further apart. Each mounting plate 20 has a scooping and clamping module 30 positioned opposite each other on the same side. During operation, the two scooping and clamping modules 30 act on the upper and lower surfaces of the photovoltaic module, respectively. The first driving member 10 is a gripper cylinder capable of simultaneously driving the mounting plates 20 to move closer or further apart. If only the scooping and clamping action of one tape head on one processing surface is required, then two scooping and clamping modules 30 are not necessary; only one scooping and clamping module 30 needs to be provided on the mounting plate 20 to perform the scooping and clamping actions of the tape head.

[0041] Therefore, in this embodiment, the tape head clamping mechanism 100 includes a first driving member 10 and a mounting plate 20 that is driven by the first driving member 10 to move. A clamping module 30 is provided on the mounting plate 20. The structure and working principle of the clamping module 30 are the same as in Embodiment 1, and will not be described again here. The difference from Embodiment 1 is that only one mounting plate 20 is provided, and one clamping module 30 is directly provided on the mounting plate 20. The first driving member 10 drives the mounting plate 20 to move towards the plane where the tape needs to be clamped. Therefore, the first driving member 10 can be set as a linear driving member, or as an XY axis driving member, or as an XYZ driving member. The setting can be made according to the actual situation, and there is no limitation here.

[0042] Example 3:

[0043] In Embodiment 2, the action of shoveling and clamping one tape head on a processing surface is completed. Therefore, a shoveling and clamping module 30 is provided on the mounting plate 20. If multiple tapes need to be removed from a processing surface, the action of shoveling and clamping multiple tape heads on the processing surface needs to be completed. The difference from Embodiment 2 is that multiple shoveling and clamping modules 30 can be set on the mounting plate 20 to shovel multiple tape heads at the same time, depending on the actual situation. The structure and working principle of the shoveling and clamping module 30 are the same as in Embodiment 1, and will not be described again here. The structure of the first driving component 10 and the mounting plate 20 are the same as in Embodiment 2, and will not be described again here. It should be noted that the size of the mounting plate 20 can be adjusted according to the size occupied by the multiple shoveling and clamping modules 30. The simultaneous shoveling and clamping of multiple tape heads by the multiple shoveling and clamping modules 30 can improve work efficiency. As for the arrangement of the multiple shoveling and clamping modules 30, it can be adjusted according to the actual layout of the tape, and is not limited here.

[0044] 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.
