Description

Technical Field

[0001] This utility model relates to the field of photovoltaic string welding machine technology, and in particular to a dual-track parallel photovoltaic string welding machine. Background Technology

[0002] A photovoltaic stringer is an automated device specifically designed to connect solar cells (usually silicon wafers) in series according to specific specifications and process requirements, forming solar cell strings. These strings are the basic units that make up solar cell modules (photovoltaic modules).

[0003] In existing technologies, in order to improve the production efficiency of photovoltaic modules, a dual-track parallel photovoltaic string welding machine is used, which means that the process is carried out simultaneously by two conveying devices. Even if one of the conveying devices malfunctions and needs to be inspected and repaired, the other can continue to operate without interruption. However, when the solar cells move to the corresponding position along the conveying mechanism, positional misalignment is likely to occur, thereby reducing the quality of subsequent welding of the components. Utility Model Content

[0004] This utility model mainly provides a dual-track parallel photovoltaic string welding machine with position adjustment and improved welding quality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dual-track parallel photovoltaic string welding machine, comprising a parallel conveying device and four strip plates, wherein forward and reverse motors are fixedly installed on the top of two of the strip plates, and bidirectional lead screws are fixedly installed on one side of the outer wall of each of the two forward and reverse motors; fixing columns are fixedly installed on the top of the other two strip plates, and guide rods are fixedly installed on one side of the outer wall of each of the two fixing columns; fixing plates are fixedly installed on the top of each of the two strip plates; moving columns are threadedly connected to the outer walls of the two bidirectional lead screws, and the inner walls of the two moving columns are movably sleeved on the outer walls of the two guide rods; and adjusting plates are fixedly installed at the bottom of each of the two moving columns.

[0006] Preferably, four rectangular plates are fixedly installed on the outer wall of the parallel conveying device, and motor mounts are fixedly installed on the top of each of the four rectangular plates.

[0007] Preferably, a drive motor is fixedly installed on the top of each of the four motor mounts, a drive rod is fixedly installed on one side of the outer wall of each of the four drive motors, and a gear is fixedly installed on the outer wall of each of the four drive rods. The controller starts the four drive motors simultaneously, so that they drive the four drive rods and four gears to rotate at the same time, thereby achieving synchronization.

[0008] Preferably, a limiting plate is fixedly installed on the top of each of the four motor bases, the outer walls of the four gears are meshed with gear racks, and the tops of the four gear racks are fixedly connected to the bottoms of the four strip plates. The four gears are driven to rotate simultaneously by the four drive rods, thereby driving the four gear racks and the strip plates to move up and down at the same time.

[0009] Preferably, two limiting rods are fixedly installed on the top of each of the four rectangular plates, and the inner surface of each of the four strip plates is movably sleeved on the outer surface of the eight limiting rods. Limiting rings are fixedly sleeved on the outer surface of each of the eight limiting rods. Through the action of the eight limiting rods and the eight limiting rings, the stability of the four strip plates moving up and down is improved, and it is ensured that the four strip plates will not detach from the eight limiting rods.

[0010] Preferably, a fixed frame is fixedly installed on the top of the parallel conveying device, and four cylinders are fixedly installed on the top of the inner wall of the fixed frame. Two welding components are fixedly installed at the output ends of the four cylinders, and two cameras are fixedly installed on the top of the fixed frame. The controller starts the four cylinders so that they can drive the two welding components to move downward and weld the battery cell that has been adjusted to the correct position, and melt the welding strip so that it is welded to the grid lines on the surface of the battery cell.

[0011] Preferably, a controller is fixedly installed on the top of the mounting bracket, and one side of the outer wall of the controller is electrically connected to the outer wall of the two forward and reverse motors, the four drive motors and the four cylinders. The controller controls the corresponding components to achieve synchronized operation.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, under the action of the camera, when the battery cell is in the designated position, the operation of the corresponding conveying device is stopped and the forward and reverse motors are started by the controller. Under the action of the fixed column, guide rod and fixed plate, the two moving columns are moved stably relative to each other, thereby driving the two adjusting plates to move stably relative to each other, and placing the battery cell on the corresponding conveying device in the center position. Then the conveying device is started again, so that it is in the designated position and reaches the bottom of the welding assembly, thereby improving the welding quality.

[0014] 2. In this utility model, the controller simultaneously starts two corresponding drive motors, which drive two drive rods and two gears to rotate. Then, under the action of four limit rods, they simultaneously drive two gear racks and two strip plates to move stably up and down along the four limit rods. Under the action of four limit rings, the two strip plates will not detach from the four limit rods, thus allowing the two strip plates to be moved to a suitable height. This can adapt to the position adjustment of battery cells of different thicknesses, ensuring the effectiveness of the position adjustment of the battery cells on the corresponding conveying device, and further ensuring the quality of subsequent welding.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Please see Figure 1-4This utility model provides a technical solution: a dual-track parallel photovoltaic string welding machine, including a parallel conveying device 1 and four strip plates 2, wherein a forward and reverse motor 3 is fixedly installed on the top of two strip plates 2, and a bidirectional lead screw 4 is fixedly installed on one side of the outer wall of the two forward and reverse motors 3. A fixing column 5 is fixedly installed on the top of the other two strip plates 2, and a guide rod 6 is fixedly installed on one side of the outer wall of the two fixing columns 5. A fixing plate 7 is fixedly installed on the top of the two strip plates 2. The outer walls of the two bidirectional lead screws 4 are threadedly connected to moving columns 8, and the inner walls of the two moving columns 8 are movably sleeved on the outer walls of the two guide rods 6. An adjustment plate 9 is fixedly installed at the bottom of the two moving columns 8.

[0024] like Figure 1 , Figure 3 and Figure 4 As shown, four rectangular plates 10 are fixedly installed on the outer wall of the parallel conveying device 1, and motor mounts 11 are fixedly installed on the top of each of the four rectangular plates 10.

[0025] like Figure 1 , Figure 3 and Figure 4 As shown, drive motors 12 are fixedly installed on the top of the four motor mounts 11, drive rods 13 are fixedly installed on one side of the outer wall of the four drive motors 12, and gears 14 are fixedly installed on the outer wall of the four drive rods 13. The controller 23 starts the four drive motors 12 at the same time, so that they drive the four drive rods 13 and the four gears 14 to rotate simultaneously, thus achieving synchronization.

[0026] like Figure 1 - Figure 3 As shown, a limiting plate 15 is fixedly installed on the top of each of the four motor bases 11, and the outer walls of the four gears 14 are meshed with the gear rack 16. The top of each of the four gear racks 16 is fixedly connected to the bottom of the four strip plates 2. The four gears 14 are driven to rotate simultaneously by the four drive rods 13, thereby driving the four gear racks 16 and the strip plates 2 to move up and down at the same time.

[0027] like Figure 1 , Figure 3 and Figure 4 As shown, two limiting rods 17 are fixedly installed on the top of each of the four rectangular plates 10, and the inner surface of each of the four strip plates 2 is movably sleeved on the outer surface of the eight limiting rods 17. Limiting rings 18 are fixedly sleeved on the outer surface of each of the eight limiting rods 17. Through the action of the eight limiting rods 17 and the eight limiting rings 18, the stability of the four strip plates 2 moving up and down is improved, and it is ensured that the four strip plates 2 will not detach from the eight limiting rods 17.

[0028] like Figure 1 and Figure 4As shown, a fixed frame 19 is fixedly installed on the top of the parallel conveying device 1. Four cylinders 20 are fixedly installed on the top of the inner wall of the fixed frame 19. Two welding components 21 are fixedly installed at the output end of the four cylinders 20. Two cameras 22 are fixedly installed on the top of the fixed frame 19. The four cylinders 20 are started by the controller 23, which can drive the two welding components 21 to move downward and weld the battery cell that has been adjusted to the correct position. The welding strip is melted and welded to the grid lines on the surface of the battery cell.

[0029] like Figure 3 and Figure 4 As shown, the controller 23 is fixedly installed on the top of the mounting bracket 19, and one side of the outer wall of the controller 23 is electrically connected to the outer wall of the two forward and reverse motors 3, the four drive motors 12 and the four cylinders 20. The controller 23 controls the corresponding components to achieve synchronized operation.

[0030] The operation and working principle of this device are as follows: First, the entire parallel conveying device 1 and welding assembly 21 are installed within a single unit. Solder strips (typically tin-plated copper strips) are laid onto the positive and negative grid lines of the solar cells. The solder strips connect the solar cells, forming a series circuit. The cells are then moved along the parallel conveying device 1, which consists of two conveying units that can operate independently. Based on the thickness of the solar cells, the controller 23 simultaneously activates four drive motors 12, which in turn drive four drive rods 13 and four gears 14. Since the toothed racks 16 mounted at the bottom of the four strip plates 2 are meshed with the four gears 14, the four toothed racks 16 and the four strip plates 2 can stably move up and down along eight limit rods 17, reaching the desired height. Then, under the action of two cameras 22, when the solar cells reach the designated position, the operation of the parallel conveying device 1 is stopped. The controller 23 simultaneously starts two forward and reverse motors 3, which drive two bidirectional lead screws 4 to rotate inside the two fixed columns 5. Since guide rods 6 are installed between the two fixed columns 5 and the two fixed plates 7, and the four moving columns 8 are movably sleeved on the two guide rods 6 in pairs, the corresponding moving columns 8 and the adjusting plate 9 can move relative to each other, and adjust the solar cell to the center position on the corresponding conveying device, which improves the quality of subsequent welding. Then, through the operation of the parallel conveying device 1, it is moved to the bottom of the two welding components 21. Then, the controller 23 starts four cylinders 20, which drive the two welding components 21 to move downward. The welding components 21 can melt the welding strip through laser welding and weld it to the grid lines on the surface of the solar cell. In general, the quality of welding the welding strip to the solar cell is improved, thereby improving the performance of the dual-track parallel photovoltaic string welding machine.
