Description

Technical Field

[0001] This utility model relates to the field of photovoltaic busbar technology, and in particular to a semi-automatic winding machine wire feeding device. Background Technology

[0002] In the photovoltaic module manufacturing process, the busbar, as an important conductor material connecting the cells, needs to undergo precise winding and cutting processes to ensure the stability of subsequent processes and product quality. As the photovoltaic industry continues to demand automation and production efficiency, traditional manual winding methods can no longer meet the needs of large-volume, high-precision production. Therefore, various types of winding equipment have emerged.

[0003] Existing photovoltaic busbars typically use fixed guiding mechanisms, requiring manual inspection of the winding thickness during the winding process and cutting when the set dimensions are reached. This method is not only labor-intensive, but also prone to deviations in the cutting position due to inaccurate human judgment, affecting the neatness and consistency of the winding.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a semi-automatic winding machine wire feeding device, including a support plate, on which a wire feeding mechanism, a guiding mechanism and a cutting mechanism are sequentially arranged. The photovoltaic busbar passes through the wire feeding mechanism and the guiding mechanism and is wound around an external winding wheel. The support plate is also provided with a lifting mechanism, which drives the guiding mechanism to rise and fall. When the busbar is wound to a set thickness, the lifting mechanism lifts the guiding mechanism above the cutting mechanism and cuts the busbar through the cutting mechanism.

[0034] The present invention will be further described below with reference to the accompanying drawings.

[0035] like Figure 1 and Figure 2 As shown, the present invention provides a semi-automatic winding machine wire feeding device, including a support plate 1. A wire feeding mechanism, a guide mechanism 2, and a cutting mechanism 3 are sequentially installed on the support plate 1. The photovoltaic busbar enters through the wire feeding mechanism and is wound around the external take-up reel under the guidance of the guide mechanism 2. A lifting mechanism 4 is also installed on the support plate 1. The lifting mechanism 4 is used to drive the guide mechanism 2 to achieve lifting action. The motor of the external take-up reel transmits data and calculates the winding thickness through a program using time, linear speed, and take-up reel size. When the busbar is detected to have wound to the set thickness, the control unit outputs a control command to drive the lifting mechanism 4 to raise the guide mechanism 2 above the cutting mechanism 3. At this time, the cutting mechanism 3 operates to cut the busbar, thereby realizing automated control and improving winding accuracy and production efficiency.

[0036] like Figure 3As shown, the guiding mechanism 2 includes a guide bracket 22 structure. Guide wheels 26, guide posts 23, and guide steel strips 24 are sequentially arranged on the guide bracket 22. The guide wheels 26 have adjustable groove widths for initial positioning. A photoelectric detection and control unit 21 located on one side of the guide wheels 26 monitors the status of the busbar in real time. The guide steel strips 24 are located below the guide posts 23. Guide gaps are formed between the two guide posts 23 and between the two guide steel strips 24. The busbar passes through these gaps sequentially, receiving effective support and precise guidance during transport, preventing deviation or twisting, and thus ensuring smooth operation during winding. The tension distribution is uniform, further improving the quality of the finished product. To enhance compatibility, a first transverse groove 221 is provided on the guide bracket 22. A movable bracket 25 is slidably mounted on the first groove 221. A second groove 251 perpendicular to the guide bracket 22 is provided on the movable bracket 25. The guide post 23 is slidably mounted in the second groove 251, allowing adjustment of the position of the guide post 23 and the width of the guide gap to accommodate different specifications of busbars and enhance the adaptability of the device. The guide bracket 22 is also equipped with an electric push rod with a built-in linear motor, which is used to lift the busbar after wire cutting to facilitate the winding of the busbar.

[0037] like Figure 1 As shown, the lifting mechanism 4 adopts a lead screw 42 structure. The lead screw 42 is installed on the lifting bracket 41 and is driven to rotate by the lifting motor 43. The guide bracket 22 and the lead screw 42 are threaded together. When the lead screw 42 rotates, it drives the guide mechanism 2 to lift smoothly. The position is controllable during the lifting process, avoiding jamming and ensuring the stability and accuracy of the entire operation.

[0038] like Figure 1 and Figure 2As shown, the wire feeding mechanism includes a first wire feeding wheel 51, a second wire feeding wheel 52, a first wire pressing assembly 53, and a second wire pressing assembly 54, which are sequentially arranged on the support plate 1. The busbar first passes through the first wire feeding wheel 51 and the second wire feeding wheel 52, and then passes through the first wire pressing assembly 53 and the second wire pressing assembly 54 in sequence for pressing. The first wire pressing assembly 53 includes a first support wheel 531 and a first wire pressing wheel 532. The first wire pressing wheel 532 is rotatably mounted on the first pressing wheel seat 534 and is driven by the first drive cylinder 533 to move the first wire pressing wheel 532 toward the first support wheel 531 to press the busbar. The structure of the second wire pressing assembly 54 is similar to that of the first wire pressing assembly 53, consisting of a second support wheel 541 and a second wire pressing wheel 542. The second wire pressing wheel 542 is rotatably mounted on the second pressing wheel seat 544 and is driven by the second drive cylinder 543 to move the second wire pressing wheel 542 toward the second support wheel 541 to press the busbar. The first and second pressure rollers 542 act on both sides of the busbar, respectively. The busbar is straightened by the drive of the first and second cylinders, thus preventing slippage, wrinkling or damage during the transport process. The first support roller 531 is driven to rotate by the first motor 11, and the second support roller 541 is driven to rotate by the second motor 12. The motor power drives the busbar to move. When winding, the first motor 11 and the second motor 12 stop running, and the first drive cylinder 533 and the second drive cylinder 543 drive the retraction. The first wire inlet roller 51, the second wire inlet roller 52, 26 and the guide roller of the busbar are finally limited by the guide post 23 and the guide steel strip 24 before winding.

[0039] like Figure 4 As shown, the cutting mechanism 3 is installed below the support plate 1 and includes a cutting bracket 31, a magnetic coupling cylinder 34, a cutting cylinder 33, and a cutting blade 32. The cutting blade 32 can move back and forth through the magnetic coupling cylinder 34, so that the cutting blade 32 can move to the cutting position of the busbar when needed and complete the cutting. The initial position of the cutting blade 32 is located behind the guide mechanism 2. After the guide mechanism 2 is raised to the predetermined position, the cutting blade 32 moves forward under the external driving action. After the cutting cylinder 33 is started, its output shaft drives the connected transmission component to rotate. The transmission component outputs the power of the cutting cylinder 33 to the cutting blade 32, driving the cutting blade 32 to close quickly and complete the cutting. The cut is flat. The whole action process is fast and reliable, reduces manual intervention, and further improves production efficiency and product consistency.

[0040] The basic working principle of this utility model is as follows: When the equipment is running, the busbar first passes through the first wire inlet wheel 51 and the second wire inlet wheel 52, then passes through the first wire pressing assembly 53 and the second wire pressing assembly 54 in sequence, and enters the guide mechanism 2. After passing the guide wheel 26, the busbar passes through the guide gap formed by the two guide posts and the lower wire steel strip 24. When the busbar on the take-up wheel reaches the set roll diameter, the control system starts the lifting mechanism 4. The lifting motor 43 drives the lead screw 42 to rotate. The guide mechanism 2 rises with the lead screw 42 and gradually rises above the cutting mechanism 3 to make room for the cutting operation. When the guide mechanism 2 moves to the designated position, the cutting mechanism 3 starts to work. The magnetic coupling cylinder 34 is activated, driving the cutting blade 32 to move forward. After the cutting blade 32 reaches the position of the busbar, it completes the cutting. After the cutting is completed, the cutting blade 32 returns to the initial position under the drive of the magnetic coupling cylinder 34. The lifting mechanism 4 drives the guide mechanism 2 to descend back to the working position. The entire device returns to the initial state and is ready for the next wire inlet and take-up operation.

Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
