Description

Technical Field

[0001] The present invention relates to the technical field of battery cell production, and in particular to a pressing device for battery cell wires. Background Art

[0002] Solar cell wire is the core connector in photovoltaic cell production. It is used to weld the positive and negative electrodes of the cell to achieve current conduction. Its performance directly affects the conversion efficiency, reliability and production cost of the cell.

[0003] During the production and processing of solar cells, there are several important reasons for pressing the wire:

[0004] Ensure close contact between the wire and the battery cell: welding quality. During the welding process, the wire needs to fit closely with the surface of the battery cell to ensure the firmness and reliability of the welding. The pressing operation can eliminate the gap between the wire and the battery cell, making the welding point tighter and reducing the problems of false welding and weak welding. Electrical connection. Good contact can ensure the quality of the electrical connection between the wire and the battery cell, reduce contact resistance, and improve the overall performance and efficiency of the battery cell.

[0005] Improve the stability of the wire: prevent shaking. During the production process, the wire may shake or move due to the vibration of the equipment or other external forces. The pressing operation can fix the position of the wire and keep it stable during the processing, avoiding welding deviation or other processing problems caused by wire movement; reduce errors. The stable wire position helps to improve the processing accuracy and consistency, and reduce product defects caused by inaccurate wire position.

[0006] Traditional cell wire compression devices have many shortcomings. For example, traditional devices usually use manual or simple mechanical adjustment, with low accuracy, generally at the millimeter level, which is difficult to meet high-precision requirements. In addition, traditional devices mostly use single-wire compression, which is inefficient in actual production and processing. Therefore, in order to solve the above problems, a cell wire compression device is designed. Summary of the Invention

[0007] Based on this, the purpose of the present invention is to provide a pressing device for battery cell wires to solve the technical problems of low precision and efficiency of traditional pressing devices.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a pressing device for battery cell wires, comprising a main body and a processing line, wherein the main body is located above the processing line, a pressing base plate is fixed to the bottom end of the main body, a pressing plate that cooperates with the pressing base plate is arranged between the main body and the pressing base plate, a hydraulic device is installed above the main body, and the output end of the hydraulic device is connected to the pressing plate, and a plurality of pressing blocks that cooperate with the pressing base plate are arranged at the bottom end of the pressing plate.

[0009] By adopting the above technical solution, the hydraulic device on the main body provides stable pressure, ensuring that the clamping block on the clamping plate cooperates with the clamping base plate to clamp the battery cell wires passing through the middle, and multiple clamping blocks allow multiple wires to be compressed at the same time, thereby improving production efficiency.

[0010] The present invention is further configured such that a plurality of threaded shafts are threaded through the pressing plate, and the bottom end of each threaded shaft is connected to the corresponding pressing block.

[0011] By adopting the above technical solution, since different battery cell wires require different clamping forces, the hydraulic device cannot accurately adjust the downward pressure. At this time, the threaded shaft is rotated to adjust the relative distance between the clamping block and the clamping base plate, thereby achieving high-precision clamping force adjustment while the hydraulic device provides constant downward pressure.

[0012] The present invention is further configured such that both sides of the top surface of the pressing base plate are rotatably connected with a plurality of guide shafts that cooperate with the pressing blocks.

[0013] By adopting the above technical solution, the design of the guide shaft ensures that the clamping block moves along a predetermined path during the clamping process, avoiding offset or jamming, and the rotating connected guide shaft reduces the friction between the clamping block and the clamping base plate, thereby improving the smoothness of movement. In addition, the guiding function of the guide shaft ensures the precise alignment of the clamping block, thereby improving the accuracy of clamping.

[0014] The present invention is further configured such that limit plates are provided on both sides of the processing line, clamping blocks are installed on both sides of the main body, and the clamping blocks are slidably connected to the corresponding limit plates, and the clamping blocks are connected to the limit plates by fixing bolts.

[0015] By adopting the above technical solution, the sliding connection design of the clamping block and the limit plate allows the main body to be adjusted in position on the processing line when necessary, increasing the flexibility of the equipment. After determining the position of the main body, the fixing bolts are tightened to fix the main body.

[0016] The present invention is further configured such that a rubber layer is provided on the bottom surface of the pressing block.

[0017] By adopting the above technical solution, the rubber layer has good anti-slip properties, ensuring good contact between the compression block and the battery cell wire, preventing the battery cell wire from sliding left and right, and the rubber layer has a certain buffering effect, which can absorb the impact force generated during the compression process and protect the wire from damage.

[0018] The present invention is further configured such that a pressure sensor is installed in the compression block.

[0019] By adopting the above technical solution, the pressure sensor can monitor the pressure applied by the clamping block to the wire in real time to ensure that the clamping force is within a reasonable range. Moreover, through the feedback of the pressure sensor, the clamping force can be accurately adjusted to avoid problems caused by excessive or insufficient pressure.

[0020] In summary, the present invention mainly has the following beneficial effects:

[0021] The present invention drives the pressing plate and the pressing block through a hydraulic device to achieve high-precision pressing of the battery cell wires, and rotates the threaded shaft according to demand to adjust the relative distance between the pressing block and the pressing base plate, thereby meeting the high-precision requirements of the battery cell wire pressing force; the rubber layer on the bottom surface of the pressing block and the internal pressure sensor respectively provide anti-slip buffering and real-time pressure monitoring functions, further improving the pressing effect and reliability.

[0028] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0029] The following describes an embodiment of the present invention based on its overall structure.

[0030] A pressing device for battery cell wires, such as Figure 1-5As shown, it includes a main body 1 and a processing line 2. The main body 1 is located above the processing line 2. A clamping base plate 4 is fixed to the bottom end of the main body 1. A clamping plate 5 that cooperates with the clamping base plate 4 is arranged between the main body 1 and the clamping base plate 4. A hydraulic device 9 is installed above the main body 1, and the output end of the hydraulic device 9 is connected to the clamping plate 5. A plurality of clamping blocks 7 that cooperate with the clamping base plate 4 are arranged at the bottom end of the clamping plate 5. The hydraulic device 9 on the main body 1 provides stable pressure to ensure that the clamping blocks 7 on the clamping plate 5 cooperate with the clamping base plate 4 to clamp the battery cell wire passing through the middle, wherein multiple clamping blocks 7 allow multiple wires to be clamped at the same time, thereby improving production efficiency.

[0031] There are several threaded shafts 6 running through the threads on the clamping plate 5, and the bottom end of each threaded shaft 6 is connected to the corresponding clamping block 7. Since the clamping force required for different battery cell wires is different, the hydraulic device 9 cannot accurately adjust the downward pressure. At this time, the threaded shaft 6 is rotated to adjust the relative distance between the clamping block 7 and the clamping base plate 4, thereby achieving high-precision clamping force adjustment under the premise that the hydraulic device 9 provides constant downward pressure.

[0032] Both sides of the top surface of the clamping base plate 4 are rotatably connected with a number of guide shafts 8 that cooperate with the clamping block 7. The design of the guide shafts 8 ensures that the clamping block 7 moves along a predetermined path during the clamping process to avoid offset or jamming, and the rotatably connected guide shafts 8 reduce the friction between the clamping block 7 and the clamping base plate 4, thereby improving the smoothness of movement. In addition, the guiding function of the guide shafts 8 ensures the precise alignment of the clamping block 7 and improves the accuracy of clamping.

[0033] Limiting plates 10 are provided on both sides of the processing line 2, and clamping blocks 3 are installed on both sides of the main body 1, and the clamping blocks 3 are slidingly connected to the corresponding limiting plates 10. The clamping blocks 3 are connected to the limiting plates 10 through fixing bolts. The sliding connection design of the clamping blocks 3 and the limiting plates 10 allows the main body 1 to be adjusted in position on the processing line 2 when necessary, thereby increasing the flexibility of the equipment. After determining the position of the main body 1, tighten the fixing bolts to fix the main body 1.

[0034] The bottom surface of the pressing block 7 is provided with a rubber layer, which has good anti-slip properties, ensuring good contact between the pressing block 7 and the battery cell wires, preventing the battery cell wires from sliding left and right, and the rubber layer has a certain buffering effect, which can absorb the impact force generated during the pressing process and protect the wires from damage.

[0035] A pressure sensor is installed in the pressing block 7. The pressure sensor can monitor the pressure applied by the pressing block 7 to the wire in real time to ensure that the pressing force is within a reasonable range. The pressing force can be accurately adjusted through the feedback of the pressure sensor to avoid problems caused by excessive or insufficient pressure.

[0036] Working principle: The main body 1 slides along the limit plate 10 through the clamping blocks 3 on both sides to ensure that the main body 1 can be adjusted in position on the processing line 2 when necessary, thereby increasing the flexibility of the equipment. After determining the position of the main body 1, tighten the fixing bolts to fix the main body 1. After starting processing, the hydraulic device 9 on the main body 1 provides stable pressure to ensure that the clamping block 7 on the clamping plate 5 cooperates with the clamping base plate 4 to clamp the battery cell wire passing through the middle. Multiple clamping blocks 7 allow multiple wires to be clamped at the same time, thereby improving production efficiency. The design of the guide shaft 8 ensures that the clamping block 7 moves along a predetermined path during the clamping process to avoid offset or jamming. In addition, since different battery cell wires require different clamping forces, the hydraulic device 9 cannot accurately adjust the downward pressure. At this time, the threaded shaft 6 is rotated to adjust the relative distance between the clamping block 7 and the clamping base plate 4, thereby achieving high-precision clamping force adjustment under the premise that the hydraulic device 9 provides constant downward pressure.

The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
