Description

Technical Field

[0001] This invention relates to the field of photovoltaic manufacturing technology, and in particular to a tearing mechanism. Background Technology

[0002] Before the lamination process in photovoltaic manufacturing, a high-temperature cloth needs to be placed on the surface of the encapsulation material layer to prevent the colloid from overflowing during the lamination process. However, during the subsequent installation with the junction box, the high-temperature cloth needs to be removed from the surface of the photovoltaic module, and the busbar needs to be rotated to a position that is approximately vertical to the surface of the photovoltaic module.

[0003] To improve the automation efficiency of photovoltaic manufacturing, a mechanical device for automatically removing high-temperature tape has been developed. This device typically includes a shovel clamp and a moving module. The shovel clamp is driven by the moving module to move to the position of the high-temperature tape, then uses the shovel clamp to scoop up the high-temperature tape and carries it away through the moving module.

[0004] In the existing technology, when the mobile module drives the shovel clamp to move to the surface of the photovoltaic module, the shovel clamp will directly contact the surface of the photovoltaic module. The hard contact between the shovel clamp and the photovoltaic module will cause a collision. In this way, the shovel clamp can easily scratch the surface of the photovoltaic module during the process of tearing off the high-temperature cloth, resulting in damage to the photovoltaic module. Summary of the Invention

[0005] The main objective of this invention is to provide a tearing mechanism that avoids hard contact between the shovel clamp and the photovoltaic module, allowing the shovel clamp to rotate elastically relative to the mounting plate, thereby buffering the impact force on the photovoltaic module, reducing the possibility of the photovoltaic module being scratched by the shovel clamp, and improving the yield rate of the photovoltaic module.

[0006] To achieve the above objectives, the present invention proposes a tearing mechanism applied to the tearing operation of high-temperature cloth on photovoltaic modules. The tearing mechanism is characterized by comprising two shovel clamping assemblies and a moving module for driving the two shovel clamping assemblies to move in multiple directions; wherein,

[0007] Each of the aforementioned shovel clamp assemblies includes a mounting plate, an elastic element, and a shovel clamp. The mounting plate is mounted on the movable module, and the shovel clamp is rotatably mounted on the mounting plate. The elastic element connects the shovel clamp to the mounting plate, allowing the shovel clamp to elastically rotate relative to the mounting plate when it comes into contact with the photovoltaic module to buffer the impact force.

[0008] In some embodiments of the present invention, the elastic element is a first spring located on the side of the shovel clamp near another shovel clamp assembly, and one end of the first spring is connected to the shovel clamp, and the other end of the first spring is connected to the mounting plate.

[0009] In some embodiments of the present invention, each of the shovel clamps includes a shovel clamp arm and a shovel clamp portion. One end of the shovel clamp portion is rotatably mounted on the mounting plate and connected to the shovel clamp arm. The other end of the shovel clamp portion is used to shovel up the high-temperature cloth. The end of the shovel clamp arm away from the shovel clamp portion is connected to the first spring, so that when the other end of the shovel clamp portion contacts the photovoltaic module, one end of the shovel clamp portion elastically rotates relative to the mounting plate to buffer the impact force.

[0010] In some embodiments of the present invention, the mounting plate is provided with a rotating shaft, and the shovel clamping part includes two shovel blades spaced apart along the axial direction of the rotating shaft. One end of each shovel blade is provided with a mounting hole, and the two mounting holes are rotatably engaged with the rotating shaft.

[0011] Each of the aforementioned shovel clamping assemblies further includes a movable shovel blade, which is rotatably mounted on the rotating shaft and located between the two shovel blades. A second spring is connected between the movable shovel blade and the shovel clamping arm, allowing the movable shovel blade to elastically rotate relative to the mounting plate when it contacts the photovoltaic module to buffer the impact force. Furthermore, the distance from the end of the movable shovel blade away from the rotating shaft to the rotating shaft is greater than the distance from the end of any of the shovel blades away from the rotating shaft to the rotating shaft, allowing the end of the movable shovel blade away from the rotating shaft to contact the photovoltaic module before the end of the shovel blade away from the rotating shaft.

[0012] In some embodiments of the present invention, each of the shovel clamp assembly further includes a movable shovel clamp and a first driving device. The movable shovel clamp is movably mounted on the shovel clamp arm, and the first driving device is drively connected to the movable shovel clamp to drive the movable shovel clamp to move relative to the shovel clamp arm, so that the movable shovel clamp has a separated state and a clamping state relative to the shovel clamp portion.

[0013] In some embodiments of the present invention, the mounting plate is provided with a limiting portion located on the side of the shovel clamp arm near another shovel clamp assembly to limit the rotational stroke of the shovel clamp arm.

[0014] In some embodiments of the present invention, the mobile module includes a frame, a second driving device, and a mobile platform. The frame has a guide rail arranged in a vertical direction. The mobile platform is mounted on the guide rail. The two shovel clamp assemblies are respectively mounted on the mobile platform. The second driving device is throttle-connected to the mobile platform to drive the two shovel clamp assemblies to move in the vertical direction along the guide rail.

[0015] In some embodiments of the present invention, the mobile stage includes a third driving device, which includes two driving units, each of which is respectively mounted on the mounting plate to drive the two mounting plates to move toward each other or away from each other in the horizontal direction.

[0016] In some embodiments of the present invention, the mobile module is further equipped with a heating component, the heating end of which is positioned facing the high-temperature cloth for supplying heat to the high-temperature cloth.

[0017] In some embodiments of the present invention, the heating assembly includes a hot air gun, the air outlet of which is positioned directly opposite the high-temperature cloth.

[0018] And / or, the mobile module is also equipped with a detector, the detection head of which is positioned facing the high-temperature cloth.

[0019] This invention, through the aforementioned technical solution, provides a tearing mechanism comprising two shovel clamp assemblies and a moving module that drives the two shovel clamp assemblies to move in multiple directions. Each shovel clamp assembly includes a mounting plate, an elastic element, and a shovel clamp. The mounting plate is mounted on the moving module, and the shovel clamp is rotatably mounted on the mounting plate. An elastic element connects the shovel clamp to the mounting plate, allowing the shovel clamp to elastically rotate relative to the mounting plate when it contacts the photovoltaic module, thus buffering the impact force. With this configuration, the moving module drives the two shovel clamp assemblies to move towards the high-temperature cloth. When the two shovel clamps contact the photovoltaic module, due to the reaction force of the photovoltaic module, the shovel clamp can rotate relative to the mounting plate, thereby avoiding hard contact and collision between the shovel clamp and the photovoltaic module. Furthermore, the elastic element connecting the shovel clamp to the mounting plate ensures that the rotation of the shovel clamp is elastic, thereby buffering the impact force, reducing the possibility of the photovoltaic module being scratched by the shovel clamp, and improving the yield rate of the photovoltaic module.

[0032] This invention proposes a tearing mechanism 100 for tearing the high-temperature cloth of photovoltaic modules. Please refer to the following references. Figures 1 to 4 In this embodiment of the invention, the tearing mechanism 100 includes two shovel clamping assemblies 10 and a moving module 20 that drives the two shovel clamping assemblies 10 to move in multiple directions.

[0033] Two shovel clamping assemblies 10 are used to clamp the high-temperature cloth 13. The moving module 20 is used to drive the movement of the two shovel clamping assemblies 10 and cooperates with the two shovel clamping assemblies 10 to take away the high-temperature cloth, thereby completing the tearing operation of the high-temperature cloth. The directions in which the moving module 20 drives the two shovel clamping assemblies 10 to move include, but are not limited to, vertical movement and horizontal movement. In the driving method of the moving module 20, its power source can be a servo motor or a cylinder. It is understood that the moving module 20 can include multiple driving modules to drive the movement of the two shovel clamping assemblies 10 in different directions.

[0034] Each shovel clamp assembly 10 includes a mounting plate 11, an elastic element 12, and a shovel clamp 13. The mounting plate 11 is mounted on the movable module 20, and the shovel clamp 13 is rotatably mounted on the mounting plate 11. An elastic element 12 is connected between the shovel clamp 13 and the mounting plate 11, so that the shovel clamp 13 can elastically rotate relative to the mounting plate 11 when it comes into contact with the photovoltaic module to buffer the impact force.

[0035] It is understood that the mounting plates 11 of the two shovel clamp assemblies 10 are respectively mounted on the moving module 20, so that the moving module 20 can drive the movement of the two shovel clamp assemblies 10 respectively. For example, the moving module 20 drives the two shovel clamp assemblies 10 to move towards each other, so that the distance between the two shovel clamps 13 gradually decreases. The moving module 20 drives the two shovel clamp assemblies 10 to move away from each other, so that the distance between the two shovel clamps 13 increases.

[0036] There are several ways in which the elastic element 12 is disposed between the shovel clamp 13 and the mounting plate 11. In one configuration, the elastic element 12 is a helical spring, which is disposed between the two shovel clamp assemblies 10, with its two ends connected to the mounting plate 11 and the shovel clamp 13, respectively. In another configuration, the elastic element 12 is a spring sheet, which is disposed on the side of the shovel clamp 13 facing away from the other shovel clamp 13. One side of the spring sheet is fixedly mounted to the mounting plate 11, and the other side of the spring sheet elastically abuts against the shovel clamp 13. In yet another configuration, the elastic element 12 is a torsion spring, with a mounting post on the mounting plate 11, and the torsion spring is mounted on the mounting post. The two ends of the torsion spring act on the mounting plate 11 and the shovel clamp 13, respectively.

[0037] It should be noted that the high-temperature cloth is usually located on the upper surface of the photovoltaic module. During the removal of the high-temperature cloth, the moving module 20 typically drives the shovel clamp assembly 10 vertically from top to bottom to the position of the high-temperature cloth. Then, the moving module 20 drives the shovel clamp assembly 10 horizontally to shovel the high-temperature cloth away from the photovoltaic module. When the shovel clamp assembly 13 moves downwards to the surface of the photovoltaic module, it contacts the photovoltaic module and can then rotate relative to the mounting plate 11. Since the elastic element 12 is located between the shovel clamp 13 and the mounting plate 11, the elastic element 12 can buffer the impact force.

[0038] Of course, the high-temperature cloth may also be located on the side surface of the photovoltaic module, and the operation of the tearing mechanism 100 is similar, which will not be described in detail here.

[0039] The present invention provides a tearing mechanism 100 comprising two shovel clamp assemblies 10 and a moving module 20 for driving the two shovel clamp assemblies 10 to move in multiple directions. Each shovel clamp assembly 10 includes a mounting plate 11, an elastic element 12, and a shovel clamp 13. The mounting plate 11 is mounted on the moving module 20, and the shovel clamp 13 is rotatably mounted on the mounting plate 11. An elastic element 12 is connected between the shovel clamp 13 and the mounting plate 11, so that when the shovel clamp 13 comes into contact with the photovoltaic module, it can elastically rotate relative to the mounting plate 11 to buffer the impact force. With this configuration, the moving module 20 drives the two shovel clamp assemblies 10 to move towards the high-temperature cloth. When the two shovel clamps 13 come into contact with the photovoltaic module, due to the reaction force of the photovoltaic module, the shovel clamps 13 can rotate relative to the mounting plate 11, thereby avoiding hard contact between the shovel clamps 13 and the photovoltaic module and causing collision. In addition, there is an elastic element 12 connecting the shovel clamps 13 and the mounting plate 11, and the rotation of the shovel clamps 13 is elastic rotation, which plays a role in buffering the impact force, reducing the possibility of the photovoltaic module being scratched by the shovel clamps 13, and improving the yield of the photovoltaic module.

[0040] In some examples, such as Figure 3 and Figure 4 As shown, the elastic element 12 is a first spring located on the side of the shovel clamp 13 near the other shovel clamp assembly 10, and one end of the first spring is connected to the shovel clamp 13, and the other end of the first spring is connected to the mounting plate 11.

[0041] Please refer to Figure 3 and Figure 4 In this embodiment, the first spring of each shovel clamp assembly 10 is located between the two shovel clamps 13. Specifically, the first spring is connected to the upper part of the shovel clamp 13. The connection method between the two ends of the first spring and the mounting plate 11 and the shovel clamp 13 can be that the connecting posts are fixedly provided in the mounting plate 11 and the shovel clamp 13 respectively. The two ends of the first spring are provided with hooks, and the two hooks are respectively fastened to the connecting posts.

[0042] With this configuration, when the shovel clamp 13 comes into contact with the photovoltaic module, the end of the shovel clamp 13 that is in contact with the photovoltaic module can be tilted upwards, while the other end of the shovel clamp 13 can move away from the other shovel clamp assembly 10. The first spring, stretched by the shovel clamp 13, can play an elastic buffering role.

[0043] In some examples, such as Figure 3 and Figure 4As shown, each shovel clamp 13 includes a shovel clamp arm 131 and a shovel clamp part 132. One end of the shovel clamp part 132 is rotatably mounted on the mounting plate 11 and connected to the shovel clamp arm 131. The other end of the shovel clamp part 132 is used to shovel up the high-temperature cloth. The end of the shovel clamp arm 131 away from the shovel clamp part 132 is connected to a first spring, so that when the other end of the shovel clamp part 132 comes into contact with the photovoltaic module, one end of the shovel clamp part 132 elastically rotates relative to the mounting plate 11 to buffer the impact force.

[0044] With this configuration, when the other end of the shovel clamp 132 contacts the photovoltaic module, the shovel clamp 13 can rotate around the end of the shovel clamp 132 that is rotatably mounted on the mounting plate 11. The shovel clamp arm 131 is connected to one end of the shovel clamp 132, and the end of the shovel clamp arm 131 away from the shovel clamp 132 is connected to the spring. In this way, the shovel clamp 132 can better stretch the first spring, thereby improving the elastic buffering effect of the first spring.

[0045] There are several ways to connect the shovel clamp arm 131 and the shovel clamp part 132. In one connection method, the shovel clamp arm 131 and the shovel clamp part 132 are fixedly connected. In another connection method, the shovel clamp arm 131 and the shovel clamp part 132 are integrally formed.

[0046] In some examples, such as Figures 2 to 4 As shown, the mounting plate 11 is provided with a rotating shaft 111, and the shovel clamping part 132 includes two shovel blades 133 arranged axially spaced along the rotating shaft 111. One end of each shovel blade 133 is provided with a mounting hole, and the two mounting holes are rotatably engaged with the rotating shaft 111.

[0047] Each shovel clamp assembly 10 also includes a movable shovel blade 14, which is rotatably mounted on the rotating shaft 111 and located between the two shovel blades 133. A second spring 15 is connected between the movable shovel blade 14 and the shovel clamp arm 131, so that when the movable shovel blade 14 contacts the photovoltaic module, it can elastically rotate relative to the mounting plate 11 to buffer the impact force. The distance from the end of the movable shovel blade 14 away from the rotating shaft 111 to the rotating shaft 111 is greater than the distance from the end of any shovel blade 133 away from the rotating shaft 111 to the rotating shaft 111, so that the end of the movable shovel blade 14 away from the rotating shaft 111 can contact the photovoltaic module before the end of the shovel blade 133 away from the rotating shaft 111.

[0048] For details, please refer to Figure 4 and Figure 5 In this embodiment, the distance from the end of the movable shovel 14 away from the rotating shaft 111 to the rotating shaft 111 is D, and the distance from the end of any shovel 133 away from the rotating shaft 111 to the rotating shaft 111 is L, where D>L. There are many possible values ​​for D and L. For example, when D is 51mm, L can be 48mm, or L can be 47mm. No specific limitation is made here.

[0049] With this configuration, each shovel blade 133 can rotate around the pivot 111. The movable shovel blade 14 located between the two shovel blades 133 can contact the photovoltaic module first, so as to provide elastic buffering for the shovel clamp assembly 10 to contact the photovoltaic module first, thereby improving the effect of elastic buffering.

[0050] Understandably, since the movable shovel 14 always contacts the photovoltaic module first, it is more prone to damage or requires frequent maintenance. The movable shovel 14 can include a detachable shovel head 133, which is used to lift the high-temperature cloth, thus facilitating replacement or maintenance. Alternatively, the two shovels 133 of the shovel clamp 132 can also be configured with detachable shovel heads.

[0051] It should be noted that after the shovel clamp 132 lifts up the high-temperature cloth, the high-temperature cloth may not completely detach from the photovoltaic module. The high-temperature cloth may also adhere to the shovel clamp 132 and be carried away. The high-temperature cloth may also completely detach from the photovoltaic module and the shovel clamp 132.

[0052] In some examples, such as Figure 3 and Figure 4 As shown, each shovel clamp assembly 10 also includes a movable shovel clamp 16 and a first drive device 17. The movable shovel clamp 16 is movably mounted on the shovel clamp arm 131. The first drive device 17 is connected to the movable shovel clamp 16 in a transmission connection to drive the movable shovel clamp 16 to move relative to the shovel clamp arm 131, so that the movable shovel clamp 16 has a separated state and a clamping state relative to the shovel clamp part 132.

[0053] With this configuration, when the shovel clamp 132 shovels up the high-temperature cloth, the first drive device 17 can drive the movable shovel clamp 16 to move, so that the movable shovel switches to the clamping state. The movable shovel clamp 16 and the shovel clamp 132 together clamp the high-temperature cloth, and then the high-temperature cloth is torn off the photovoltaic module and taken away by the drive of the moving module 20.

[0054] In this embodiment, the movable shovel clamp 16 includes a driving part, a mating part, and a rotating mounting part connected between the driving part and the mating part. The mating part is used to cooperate with the shovel blade 133 to clamp the high-temperature cloth. The rotating mounting part is used to rotate and mount the shovel clamp arm 131. The driving part is used to connect to the output end of the first driving device 17, which is a cylinder. The cylinder drives the movable shovel clamp 16 to switch between a separated state and a clamping state.

[0055] Considering that when the shovel clamp 132 is not in contact with the photovoltaic module, the shovel clamp arm 131 will shift to the inside of the two shovel clamp assemblies 10 due to the tension of the first spring, the rotation of the shovel clamp 132 will be affected by many factors when it comes into contact with the photovoltaic module, such as the first spring being compressed or stuck by the shovel clamp assembly 10.

[0056] In some examples, such as Figure 3 and Figure 4 As shown, the mounting plate 11 is provided with a limiting part 112, which is located on the side of the shovel clamp arm 131 near the other shovel clamp assembly 10, to limit the rotation stroke of the shovel clamp arm 131. This arrangement can keep the first spring in a stretched state at all times, making it less likely to fall off or shift, and providing better elasticity.

[0057] In some examples, such as Figure 1 and Figure 2 As shown, the mobile module 20 includes a frame 21, a second drive device 22, and a moving platform 23. The frame 21 has a guide rail arranged in a vertical direction. The moving platform 23 is mounted on the guide rail. Two shovel clamp assemblies 10 are respectively mounted on the moving platform 23. The second drive device 22 is connected to the moving platform 23 for transmission, so as to drive the two shovel clamp assemblies 10 to move in the vertical direction along the guide rail.

[0058] With this configuration, the second drive device 22 can drive the moving platform 23 to move on the guide rail, thereby moving the two shovel clamp assemblies 10 mounted on the moving platform 23, so that the two shovel clamps 13 can move vertically along the guide rail, thereby approaching the high-temperature cloth or taking the high-temperature cloth away from the photovoltaic module.

[0059] In some examples, such as Figures 1 to 3 As shown, the mobile stage 23 includes a third drive device 231, which includes two drive units. Each drive unit is equipped with a mounting plate 11 to drive the two mounting plates 11 to move towards each other or away from each other in the horizontal direction.

[0060] With this configuration, the third drive device 231 can drive the two shovel clamp assemblies 10 to move towards each other, so that the distance between the two shovel clamps 13 gradually decreases, thereby shoveling up the high-temperature cloth. After the moving module 20 continues to move the shovel clamp assembly 10 to the designated position, the third drive device 231 can drive the two shovel clamp assemblies 10 to move away from each other, so that the distance between the two shovel clamps 13 increases, thereby releasing the high-temperature cloth to complete one tearing operation.

[0061] Considering the strong adhesiveness of the high-temperature cloth, the shovel clamp assembly 10 requires a large force to scoop up the high-temperature cloth, which can easily scratch the surface of the photovoltaic module.

[0062] In some examples, such as Figure 1 As shown, the movable module 20 is also equipped with a heating component 30, with the heating end 31 of the heating component 30 facing the high-temperature cloth to deliver heat to it. This configuration allows the heating component 30 to soften the adhesive of the high-temperature cloth, enabling the shovel clamping assembly 10 to more effectively tear off the cloth.

[0063] In some embodiments, the moving stage 23 includes a substrate 232 mounted on a guide rail, and a third driving device 231 mounted on the substrate 232. The heating component 30 may be mounted on the substrate 232 or fixed on the third driving device 231.

[0064] In some examples, such as Figure 1 and Figure 2 As shown, the heating assembly 30 includes a hot air gun with its outlet facing the high-temperature fabric. The moving module 20 is also equipped with a detector 40, with its detection head facing the high-temperature fabric. This configuration allows the hot air gun to heat a wider area, ensuring the high-temperature fabric is heated evenly and easier to remove the adhesive, thus improving the efficiency of tearing the high-temperature fabric. The detector 40 can detect the position of the high-temperature fabric to precisely control the heating range of the hot air gun, and it can also detect whether the high-temperature fabric has been successfully torn.

[0065] The detector 40 can be a photoelectric sensor, which detects the high-temperature fabric by generating an optical path 41 in the detection head. The fixing method of the detector 40 is similar to that of the heating assembly 30, and will not be described in detail here.

[0066] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
