[0002] Photovoltaic welding ribbon, also known as tinned copper ribbon or tin-coated copper ribbon, is used to connect photovoltaic module cells and plays an important role in conducting electricity. Generally, photovoltaic welding ribbons need to be tinned, pressed, quenched, annealed, etc. during production. Since photovoltaic welding ribbons are thin strips, they need to be corrected during each processing step.

[0003] The currently available photovoltaic welding tape winding equipment only rolls the photovoltaic welding tape onto a reel and reels and releases the material through a motor or pulling force. However, this method can easily cause the photovoltaic welding tape to loosen on the reel or detach from the reel. In addition, the reel has no external force to restrain it, and the reel is prone to self-rotation or cannot stop in time when rotated by external force, thereby affecting the processing quality of the photovoltaic welding tape and causing waste of raw materials.

In addition, if there are terms such as "first", "second", etc., they are also used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0032] In addition, in the description of the present invention, unless otherwise clearly defined, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0033] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0034] This embodiment relates to a feeding device for photovoltaic ribbon processing, the overall structure of which is as follows: Figure 1 and Figure 2 As shown, it includes a base 1, a column 2, a reel 3, a tensioning mechanism 4, and a pressing mechanism 5.

[0035] Among them, the processing equipment is arranged on the base 1, the column 2 is fixedly arranged on the base 1 and is located on one side of the processing equipment, the reel 3 is rotatably arranged at the top of the column 2, the photovoltaic welding tape is rolled up in the reel 3, the tensioning mechanism 4 is fixedly arranged on the top of the column 2 and abutted against the reel 3, and the clamping mechanism 5 is fixedly arranged on the top of the column 2 and abutted against the photovoltaic welding tape rolled up on the reel 3.

[0036] It is worth mentioning that the processing equipment adopts shearing equipment or tinning equipment, etc., which is a common photovoltaic welding tape processing equipment in the prior art and will not be described in detail here. The column 2 is vertically arranged on one side of the processing equipment and is installed on the base 1 to ensure that the reel 3 is close to the inlet of the processing equipment. The reel 3 rotates at the top of the column 2 to facilitate the photovoltaic welding tape to enter the processing equipment. The photovoltaic welding tape is wound on the reel 3 to facilitate the transportation of the photovoltaic welding tape into the processing equipment. The tensioning mechanism 4 can increase the friction of the reel 3 when the reel 3 rotates, thereby ensuring that the reel 3 can be fixed in this position when it stops, and can also ensure that it can stop quickly when not driven by external force and will not continue to rotate due to inertia. The clamping mechanism 5 is fixed on one side of the reel 3. When the photovoltaic welding tape is output, it can ensure that the photovoltaic welding tape is transported out through the clamping mechanism 5 to avoid the photovoltaic welding tape being loosely wound in the reel 3, thereby affecting the processing quality of the photovoltaic welding tape.

[0037] Based on the above overall introduction, an exemplary structure of the feeding device for photovoltaic ribbon processing in this embodiment is as follows: Figure 2 As shown, a motor 6 is fixedly arranged on the top of the column 2, a vertical plate 7 is fixedly mounted on the motor 6, and the driving end of the motor 6 passes through the vertical plate 7 and is fixedly connected to the reel 3. The central axis of the reel 3 is inserted at the driving end of the motor 6, and stress rings 8 are arranged on both sides of the reel 3, and the two stress rings 8 clamp the reel 3.

[0038] It should be noted that the motor 6 is fixedly mounted on the top of the column 2, and the reel 3 is mounted on the driving end of the motor 6. The motor 6 drives the reel 3 to rotate, and the tensioning mechanism 4 and the clamping mechanism 5 are fixedly mounted on the vertical plate 7 to ensure that they will not affect the rotation of the reel 3. In other words, the vertical plate 7 can be fixedly mounted on the body of the motor 6, and can also be fixedly mounted on the top of the column 2. The central axis of the reel 3 is passed through the driving end of the motor 6 to ensure that the reel 3 can rotate around the center of the circle to ensure the uniformity of the photovoltaic welding tape transportation. The two stress rings 8 tighten the reel 3, and the two stress rings 8 are screwed to the driving end of the motor 6 to ensure that the reel 3 can be tightened and the disassembly and assembly of the reel 3 is convenient.

[0039] As a preferred embodiment, Figure 3 and Figure 4 As shown, in this embodiment, the tensioning mechanism 4 includes a horizontal plate 401 fixedly arranged on the vertical plate 7, and a friction block 402 arranged on the horizontal plate 401, a screw 403 is fixedly arranged on the friction block 402, the screw 403 is screwed on the horizontal plate 401, and the friction block 402 abuts against the side wall of the reel 3. A strip hole 404 is opened on the horizontal plate 401, the screw 403 slides in the strip hole 404, a nut 405 is screwed on the screw 403, and the horizontal plate 401 is clamped between the nut 405 and the friction block 402.

[0040] It should be noted that the horizontal plate 401 can be fixed to the vertical plate 7 by screws to ensure that the friction block 402 is located on one side of the reel 3, and the friction block 402 abuts against the reel 3. When the reel 3 rotates, the friction block 402 can increase the friction force of the reel 3, thereby ensuring that the reel 3 can stop quickly when not driven by external force, avoiding inaccurate length of the photovoltaic welding tape. The screw 403 is convenient to abut against the horizontal plate 401, thereby facilitating the fixing of the friction block 402. When the screw 403 is rotated to different positions, different friction forces can be achieved. Degree, of course, the opened strip hole 404 can facilitate the lateral movement of the friction block 402, ensuring that the friction block 402 can generate friction with different positions of the reel 3, which can protect the service life of the reel 3 and generate different friction forces. Because the reel 3 will generate centrifugal force when rotating, that is to say, the friction block 402 can generate different friction forces at different positions of the reel 3, and two nuts 405 can be set, and the nut 405 is screwed on the screw rod 403 to clamp the cross plate 401, which is convenient for fixing the friction block 402.

[0041] As a preferred embodiment, Figure 5 and Figure 6 As shown, in this embodiment, the clamping mechanism 5 includes a slide bar 501 fixedly arranged on the vertical plate 7, and a slider 502 slidably arranged on the slide bar 501, a cross bar 503 is arranged on the slider 502, and a spring 504 is fixedly arranged on the cross bar 503, and the spring 504 abuts against the photovoltaic welding strip. Two slide bars 501 are arranged opposite to each other, and the slider 502 is slidably arranged on the two slide bars 501, and the axial direction of the slide bar 501 is parallel to the radial direction of the reel 3. A groove 505 is provided on the cross bar 503, and the photovoltaic welding strip is inserted into the groove 505.

[0042] It should be noted that the slide bar 501 is fixedly mounted on the vertical plate 7 to ensure that the slide bar 501 does not affect the rotation of the reel 3. At least two slide bars 501 are provided to ensure the stability of the slide bar 501 when sliding, and the slider 502 is located at the outermost edge of the circumferential direction of the reel 3. Since the axial direction of the slide bar 501 is parallel to the radial direction of the reel 3, that is, the radial sliding of the slider 502 along the reel 3 can drive the sliding of the cross bar 503. The axial direction of the cross bar 503 is parallel to the axial direction of the reel 3, ensuring that the output position of the photovoltaic welding ribbon can be adjusted by the cross bar 503 during output. That is to say, the photovoltaic welding ribbon is placed on the cross bar 503, and the spring piece 504 is inserted into the reel 3, the spring piece 504 and the photovoltaic welding ribbon are in contact, and the cross bar 503 can drive the spring piece 504 to move when adjusting the position, ensuring that the spring piece 504 can be adjusted and always in contact with the photovoltaic welding ribbon. Such a setting can ensure that the photovoltaic welding ribbon is tightly wound on the photovoltaic welding ribbon, thereby ensuring that the output distance of the photovoltaic welding ribbon is constant, and the setting of the groove 505 is for the insertion of the photovoltaic welding ribbon, and the photovoltaic welding ribbon can be transported in the groove 505, avoiding the deviation of the photovoltaic welding ribbon during output, thereby improving the output accuracy.

[0043] The feeding device for processing the photovoltaic welding ribbon in this embodiment ensures that the photovoltaic welding ribbon can be rolled up on one side of the processing equipment through the coordinated arrangement of the column 2 and the reel 3, which is convenient for feeding and unloading. The tensioning mechanism 4 is arranged to ensure that the reel 3 can generate a certain resistance when rotating to prevent the reel 3 from rotating due to inertia and self-gravity, and ensure that it can be fixed in this position when stopped. The clamping mechanism 5 is arranged to ensure that the photovoltaic welding ribbon can be tightly wound on the reel 3 to prevent it from loosening on the reel 3.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
