Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cell production equipment technology, specifically a belt quick-release string welding device. Background Technology

[0002] String welding machines are a key piece of equipment in photovoltaic (PV) module production lines, primarily used to connect multiple solar cells into strings using welding ribbons. They are an indispensable component in PV module manufacturing, not only improving production efficiency and product quality but also driving the progress and development of the entire PV industry.

[0003] The cell transfer assembly at the cell welding station typically uses a belt conveyor. Due to the high temperature at the welding station, the belt needs periodic replacement after prolonged use. Traditionally, this involves loosening the belt tensioner, removing the entire welding station clamp assembly in front of the tensioner pulley, and then removing the connecting plate that secures the tensioner pulley. This process is time-consuming and labor-intensive, and the welding station clamps require readjustment of their position and height when reinstalled. Therefore, a quick-release welding belt device is needed that doesn't alter the mechanical position of the welding station clamps, facilitating both belt removal and reassembly. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a quick-release belt welding device, which has the advantage of being able to quickly disassemble the belt. This solves the problem that the traditional method of replacing the belt involves first loosening the belt tensioning rod, then removing the entire welding station clamp assembly in front of the belt tensioning wheel, and then removing the connecting plate that fixes the belt tensioning wheel. This method is not only time-consuming and labor-intensive, but also requires readjusting the position and height of the welding station clamp when it is reinstalled.

[0005] To achieve the aforementioned purpose of quick-release belts, this utility model provides the following technical solution: a belt quick-release welding device, comprising a frame, a first drive wheel rotatably connected to one end of the frame, a motor fixedly connected to the first drive wheel on one side of the frame, a base plate fixedly connected to the end of the frame away from the first drive wheel, a second drive wheel slidably connected to the bottom of the frame, first tail clamps fixedly connected to both sides of the frame along its length, gaps between the two first tail clamps and the base plate, and a third drive wheel rotatably connected between the two first tail clamps. The first drive wheel, the second drive wheel, and the third drive wheel are connected by belt drive.

[0006] Preferably, both of the first tail clips are threaded to the outer sides with tail clip connectors, and both tail clip connectors are threaded to the base plate.

[0007] Preferably, the bottom of both sides of the frame along the length direction is slidably connected to sliders, and the two sliders are rotatably connected to the second drive wheel.

[0008] Preferably, the two sliders are fixedly connected by a fixed base, and a cylinder is fixedly connected to the side of the fixed base away from the base plate, and the output end of the cylinder is fixedly connected to the frame.

[0009] Preferably, the bottom of each of the two first tail clamps is provided with a first shaft groove, and the two ends of the third drive wheel are respectively rotatably connected to the two first shaft grooves. The bottom of each of the two first shaft grooves is provided with a first shaft baffle, and the two first shaft baffles are respectively threadedly connected to the two first tail clamps.

[0010] Preferably, the frame is fixedly connected to two second tail clamps on both sides along its length, the frame is fixedly connected to the motor through the second tail clamps, and the first drive wheel is rotatably connected between the two second tail clamps.

[0011] Preferably, the bottom of each of the second tail clips is provided with a second shaft groove, and the bottom of each of the two second shaft grooves is provided with a second shaft baffle, and the two second shaft baffles are respectively threaded to the two second tail clips.

[0012] Preferably, both of the second shaft grooves are rotatably connected to the fourth drive wheel, which is connected to a belt drive.

[0013] Compared with the prior art, this utility model provides a belt quick-release welding device, which has the following advantages:

[0014] This quick-release belt welding device, through the use of a cylinder, first controls the cylinder to retract during belt removal. The belt tension drives the second drive wheel towards the center of the frame, loosening the belt. Then, the bolts between the tail clamp connector and the base plate are removed, followed by the bolts between the tail clamp connectors, allowing the tail clamp connector to be removed. Next, the first and second shaft baffles on the same side as the removed tail clamp connector are removed, allowing the third and fourth drive wheels to be removed. The belt can then be pulled out from the gap between the first tail clamp and the base plate. After belt removal, a new belt is installed in the reverse order. This invention achieves the goal of quick belt removal, solving the problem of the traditional method in the prior art, which involves first loosening the belt tensioning rod, then removing the entire welding station clamp assembly in front of the belt tensioning wheel, and then removing the connecting plate that fixes the belt tensioning wheel. This method is not only time-consuming and labor-intensive, but also requires readjustment of the position and height when the welding station clamp is reinstalled. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1, please refer to Figure 1-3A belt quick-release string welding device includes a frame 1. A first drive wheel 2 is rotatably connected to one end of the frame 1. A motor 3, which is driven by the first drive wheel 2, is fixedly connected to one side of the frame 1. A base plate 101 is fixedly connected to the end of the frame 1 away from the first drive wheel 2. A second drive wheel 4 is slidably connected to the bottom of the frame 1. First tail clamps 5 are fixedly connected to both sides of the frame 1 along its length. Gaps are left between the two first tail clamps 5 and the base plate 101 for removing the belt 7. Tail clamp connectors 51 are threaded to the outer sides of the two first tail clamps 5 to prevent the belt 7 from falling off during operation of the string welding machine. Both tail clamp connectors 51 are threaded to the base plate 101. Sliding sliders 8 are slidably connected to the bottom of both sides of the frame 1 along its length. All blocks 8 are rotatably connected to the second drive wheel 4. The two sliders 8 are fixedly connected to each other through a fixed seat 9. A cylinder 10 is fixedly connected to the side of the fixed seat 9 away from the base plate 101. The output end of the cylinder 10 is fixedly connected to the frame 1. The bottom of the two first tail clips 5 is provided with a first shaft groove. The two ends of the third drive wheel 6 are rotatably connected to the two first shaft grooves respectively. The bottom of the two first shaft grooves is provided with a first shaft baffle 11. The two first shaft baffles 11 are threadedly connected to the two first tail clips 5 respectively. The two first tail clips 5 are rotatably connected to the third drive wheel 6. The first drive wheel 2, the second drive wheel 4 and the third drive wheel 6 are connected by a belt 7. The first drive wheel 2, the second drive wheel 4 and the third drive wheel 6 are used to apply pressure to the belt 7 to make the belt 7 more taut.

[0023] Example 2, please refer to Figure 4-5 This embodiment is a further optimization based on Embodiment 1. The parts identical to the aforementioned technical solutions will not be repeated here, as shown in Figures 1-3. Furthermore, to better realize the present invention, the following configuration is specifically adopted:

[0024] The frame 1 is fixedly connected to two second tail clamps 12 on both sides along its length. The frame 1 is fixedly connected to the motor 3 through the second tail clamps 12. The first drive wheel 2 is rotatably connected between the two second tail clamps 12. The bottom of each second tail clamp 12 is provided with a second shaft groove. The bottom of each second shaft groove is provided with a second shaft baffle 13. The two second shaft baffles 13 are threadedly connected to the two second tail clamps 12 respectively. The inside of each second shaft groove is rotatably connected to a fourth drive wheel 14. The fourth drive wheel 14 is connected to the belt 7 for transmission. The fourth drive wheel 14 is used to apply pressure to the belt 7 to make the belt 7 more taut.

[0025] In summary, this belt quick-release welding device, by incorporating a cylinder 10, first controls the cylinder 10 to retract during belt disassembly. The tension of the belt 7 drives the second drive wheel 4 towards the center of the frame 1, thereby releasing the belt 7. Then, the bolts between the tail clamp connector 51 and the base plate 101 on one side are removed, followed by the removal of the bolts between the tail clamp connectors 51, allowing the tail clamp connector 51 to be removed. Finally, the first shaft baffle 11 and the second shaft baffle 13 on the same side as the removed tail clamp connector 51 are removed, thus allowing the third drive wheel to be disassembled. The driving wheel 6 and the fourth drive wheel 14 are removed, and then the belt 7 can be pulled out from the gap between the first tail clamp 5 and the base plate 101. After the belt is removed, the new belt can be installed in the reverse order. Thus, this application achieves the purpose of quick belt removal and solves the problem that the traditional belt replacement method in the prior art is to first loosen the belt tensioning rod, then remove the entire welding station clamp assembly in front of the belt tensioning wheel, and then remove the connecting plate that fixes the belt tensioning wheel. This is not only time-consuming and labor-intensive, but also requires readjustment of position and height when the welding station clamp is reinstalled.
