Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module manufacturing technology, specifically to a busbar coating removal mechanism and a busbar cutting device. Background Technology

[0002] The commonly used busbars in photovoltaic modules are copper strips plated with tin on both sides, giving them a silver-white appearance. To improve the aesthetics of photovoltaic modules, busbars with one side black and the other silver-white are used. The black substance is a black coating adhering to the surface of the copper strip, which has insulating properties. When soldering to the junction box, the black coating on the surface of the busbar and the soldering area must be removed beforehand.

[0003] In existing technology, a scraper and roller are used to remove the black coating from the surface of the busbar. The tin-plated side of the busbar contacts the roller, the scraper squeezes the black coating, and pulls the busbar to move it a target distance, causing the black coating to detach from the copper strip at that target distance. This coating removal method requires high precision in the installation of the scraper and roller, and the roller is prone to damage during long-term use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a busbar coating removal mechanism and a busbar cutting device.

[0005] To achieve the above objectives, this utility model provides the following solution:

[0006] On one hand, this utility model provides a manifold coating removal mechanism, including: a pull-belt gripper, a mounting plate, and a scraper and a movable plate disposed on the mounting plate. The scraper is vertically and vertically disposed below the movable plate. Along a first direction, the movable plate is slidably connected to the mounting plate. The pull-belt gripper is disposed on one side of the scraper and is used to pull the manifold along the first direction. After the scraper moves upward, it squeezes the manifold at the bottom of the movable plate.

[0007] Furthermore, along the first direction, a guide cavity is provided in the mounting plate, and a spring is provided in the guide cavity. A pressure plate is fixed on the moving plate, and the mounting plate is also provided with an elongated groove communicating with the guide cavity. The end of the pressure plate extends through the elongated groove into the guide cavity and abuts against one end of the spring. When the moving plate moves along the first direction, the pressure plate compresses the spring.

[0008] Furthermore, the mounting plate is also provided with a liftable scraper, which is located between the pull belt clamp and the scraper.

[0009] Furthermore, the top surface of the scraper is opposite to the bottom surface of the moving plate.

[0010] Furthermore, the mounting plate is also provided with a brush, which is located between the pull belt clamp and the scraper. When the pull belt clamp pulls the busbar, the brush comes into contact with the busbar.

[0011] Furthermore, the scraper is mounted on the blade holder, the scraper plate is mounted on the connecting seat, the blade holder and the connecting seat are slidably connected to the mounting plate, and the mounting plate is also provided with a first cylinder and a second cylinder, the first cylinder being driven connected to the blade holder, and the second cylinder being driven connected to the connecting seat.

[0012] On the other hand, this utility model provides a tape cutting device, including: a base frame, a cutter, a material roll, and a busbar coating removal mechanism. The tape pulling claw, the cutter, the mounting plate, and the material roll are sequentially arranged on the base frame.

[0020] The technical solution and effects of this utility model will be further described in detail below with reference to the accompanying drawings.

[0021] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two elements or the interaction between two elements. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature include the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" of the second feature include the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0022] In the description of this embodiment, terms such as "upper," "lower," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used solely for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. It should also be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish between a first feature and a second feature, and do not necessarily require or imply any such actual relationship or order between these features.

[0023] like Figures 1-3As shown, this utility model provides a manifold coating removal mechanism, including: a pull gripper 10, a mounting plate 20, a scraper 21 and a movable plate 22 disposed on the mounting plate 20. The scraper 21 is vertically and vertically disposed below the movable plate 22. The movable plate 22 is slidably connected to the mounting plate 20 along a first direction. The pull gripper 10 is disposed on one side of the scraper 21 and is used to pull the manifold 50 along the first direction. After the scraper 21 moves upward, it squeezes the manifold 50 against the bottom of the movable plate 22.

[0024] When removing the black coating from the surface of the busbar 50, the pull gripper 10 clamps the end of the busbar 50, and the scraper 21 moves upward to press the busbar 50. The upper surface of the busbar 50 is in close contact with the bottom of the moving plate 22. The pull gripper 10 pulls the busbar 50 to move a target distance along the first direction. Under the action of static friction, the moving plate 22 follows the busbar 50 and moves along the first direction. The scraper 21 removes the black coating from the lower surface of the busbar 50 at the target distance. In this invention, the scraper 21 is always directly below the moving plate 22. The moving plate 22 and the busbar 50 move simultaneously and remain relatively stationary, thus preventing damage to the tin layer on the upper surface of the busbar.

[0025] In an optional embodiment of this utility model, a guide cavity is provided in the mounting plate 20 along the first direction, and a spring 224 is provided in the guide cavity. The mounting plate 20 is an inverted L-shaped plate or a vertical plate. The guide cavity is located above or to one side of the moving plate 22. A pressure plate 221 is fixed on the moving plate 22. The mounting plate 20 is also provided with an elongated groove communicating with the guide cavity. The end of the pressure plate 221 extends through the elongated groove into the guide cavity and abuts against one end of the spring 224. When the moving plate 22 moves along the first direction, the pressure plate 221 compresses the spring 224. The moving plate 22 is slidably connected to the mounting plate 20 through a sliding block 222 and a slide rail 223 that cooperate with each other. After the black coating at the target distance on the surface of the busbar 50 is removed, the spring 224 is compressed, the scraper 21 moves down and separates from the busbar 50. Under the action of the spring 224, the pressure plate 221 drives the moving plate 22 to move in the opposite direction and reset.

[0026] In an optional embodiment of this utility model, the mounting plate 20 is further provided with a liftable scraper 23, which is located between the pull belt clamp 10 and the scraper 21. After the black coating at the target distance is removed by the scraper 21, due to the inherent characteristics of the black coating, some black coating will accumulate at the end of the removal area and adhere to the busbar 50. At this time, the scraper 23 moves upward and contacts the busbar 50. As the busbar 50 continues to move, this accumulated black coating can be removed after contacting the scraper 23.

[0027] In an optional embodiment of this invention, the top surface of the scraper 23 is opposite to the bottom surface of the moving plate 22. After the scraper 23 moves upward and contacts the busbar 50, it presses the busbar 50 against the bottom of the moving plate 22, thus removing the accumulated black coating without deforming the busbar 50.

[0028] In an optional embodiment of this utility model, the mounting plate 20 is also provided with a brush 24, which is located between the pull belt clamp 10 and the scraper 23. When the pull belt clamp 10 pulls the manifold 50, the brush 24 contacts the manifold 50 to remove the black coating scum adhering to the surface of the manifold 50.

[0029] In an optional embodiment of this utility model, the scraper 21 is mounted on the blade holder 211, and the scraper 23 is mounted on the connecting seat 231. Both the blade holder 211 and the connecting seat 231 are slidably connected to the mounting plate 20. The mounting plate 20 is also provided with a first cylinder 212 and a second cylinder 232. The first cylinder 212 is driven to the blade holder 211, and the second cylinder 232 is driven to the connecting seat 231. The first cylinder 212 and the second cylinder 232 respectively drive the scraper 21 and the scraper 23 to move up and down.

[0030] like Figure 4 As shown, this utility model also provides a busbar coating removal mechanism, including: a base frame, a cutter 30, a material roll 40 and a busbar coating removal mechanism. The pull-belt clamp 10, the cutter 30, the mounting plate 20 and the material roll 40 are sequentially arranged on the base frame. The material roll 40 is used to provide the busbar 50, and the cutter 30 is used to cut the busbar 50 pulled out by the pull-belt clamp 10. The cut busbar 50 is used to weld to the junction box.

[0031] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the present utility model.
