Description

Technical Field

[0001] This utility model relates to the photovoltaic field, and in particular to a wire-laying device. Background Technology

[0002] Photovoltaic solder ribbon is an important component of photovoltaic modules, belonging to electrical connection parts. It is used to connect photovoltaic cells in series or parallel, playing a vital role in conducting and concentrating electricity to improve the output voltage and power of the photovoltaic module. Photovoltaic solder ribbon consists of a substrate and a surface coating. The substrate is usually made of copper, and the surface coating needs to be uniformly coated on the surface of the copper substrate according to a certain composition ratio and thickness. Annealing of the substrate and tinning are the two main processes in the processing of photovoltaic solder ribbon.

[0003] The substrate used for welding strips is usually placed in rolls before processing. During processing, the substrate needs to be drawn from the rolls onto the equipment. In traditional operations, manual wire feeding is required, which is labor-intensive. In addition, frequent machine stops are required to replace the substrate rolls during continuous processing, further increasing the workload and resulting in excessively high labor costs. In order to improve efficiency, existing welding strip processing systems tend to use multi-line processing. The existing wire feeding method cannot withstand the increased workload.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wire feeding device includes a wire feeding frame, a multi-path wire feeding mechanism, and a multi-path traction mechanism. The wire feeding mechanism has a cage-like structure and a receiving cavity for holding the rolled substrate is formed inside the wire feeding mechanism. One end of the receiving cavity forms a wire feeding outlet. The multi-path traction mechanism is disposed on the wire feeding frame and corresponds sequentially to the wire feeding outlet of the multi-path wire feeding mechanism.

[0007] Furthermore, the wire feeding mechanism includes an inner core and a peripheral portion, with the receiving cavity formed between the inner core and the peripheral portion, and the wire feeding outlet located at the top of the receiving cavity.

[0008] Furthermore, the accommodating cavity extends vertically upward to form a predetermined height.

[0009] Furthermore, the traction mechanism also includes a first tensioning wheel and a second tensioning wheel. The number of first tensioning wheels is set to at least two, and the second tensioning wheel is disposed between two adjacent first tensioning wheels and abuts against the substrate.

[0010] Furthermore, it also includes a fixing plate for mounting the first tensioning wheel and the second tensioning wheel, the second tensioning wheel being detachably connected to the fixing plate, and the second tensioning wheel forming multiple predetermined intervals with the first tensioning wheel.

[0011] Furthermore, the traction mechanism also includes a straightening component, which includes two straightening rollers arranged opposite each other on their circumferential surfaces, with a gap formed between the two straightening rollers for the substrate to pass through.

[0012] Furthermore, a take-up wheel is provided on one side of the wire feeding frame, and a base material is laid between the take-up wheel and the guide wheel.

[0013] Furthermore, the number of the gathering wheels is the same as the number of the traction mechanisms, and they are arranged in a corresponding order.

[0014] Furthermore, it also includes a base, to which the wire feeding mechanism is rotatably connected.

[0015] In summary, the advantages of this utility model are as follows:

[0021] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0022] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0023] In this embodiment of the invention, all directional indicators (such as up, down, left, right, front, back, horizontal, vertical, etc.) are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indicator will also change accordingly.

[0024] Due to installation errors and other reasons, the parallel relationship referred to in the embodiments of this utility model may actually be an approximate parallel relationship, and the perpendicular relationship may actually be an approximate perpendicular relationship.

[0025] This embodiment provides a wire feeding device, referring to... Figure 1 As shown, it includes multiple wire feeding mechanisms 2 and multiple traction mechanisms 3 set on the wire feeding frame 1. The multiple traction mechanisms 3 are arranged sequentially along the crossbeam of the wire feeding frame 1. The multiple wire feeding mechanisms 2 and the multiple traction mechanisms 3 are arranged in a one-to-one correspondence in number and position to realize the wire feeding of multiple substrates.

[0026] The wire feeding mechanism 2 has a cage-like structure with one open end, as shown in the reference. Figure 2 As shown, it includes an inner core portion 21 and an outer periphery portion 22, which are coaxially arranged and both extend along the height direction, such that a receiving cavity 23 for accommodating a substrate reel is formed between the outer periphery of the inner core portion 21 and the inner periphery of the outer periphery portion 22. The opening of the wire feeding mechanism 2 is provided at the top to form a wire feeding outlet for the substrate wire to exit.

[0027] In this preferred embodiment, the inner core 21 has a cylindrical structure, and the substrate is wound around the outer periphery of the inner core 21. The outer periphery 22 is located around the outer periphery of the substrate to form an enclosure, preventing the wound substrate from unwinding during the unwinding process. The unwinding end of the substrate is set outward at the unwinding outlet on the corresponding traction mechanism 3. The traction of the traction mechanism 3 causes the substrate to be continuously unwound from the accommodating cavity 23. The extension of the accommodating cavity 23 along the height direction provides a large accommodating space for the substrate reel, thereby greatly increasing the storage capacity of the substrate and greatly reducing the replacement frequency of the substrate reel, greatly reducing the frequency of manual operation on the production line, and greatly reducing labor costs.

[0028] Furthermore, when the substrate in the current receiving cavity 23 is about to be completely discharged, the winding end of the current substrate can be led out, and a new feeding mechanism 2 equipped with a roll replacement substrate can be set up to connect the winding end of the current substrate with the feeding end of the replacement substrate, thereby realizing the connection between the current substrate and the replacement substrate. When all the substrate in the current feeding mechanism 2 is discharged, the current feeding mechanism 2 can be directly removed and the replacement feeding mechanism 2 can be set in the original position of the current feeding mechanism 2, thereby realizing continuous feeding without stopping the machine.

[0029] In some other embodiments, the wire feeding mechanism 2 may also include a base, with the inner core 21 and the outer periphery 22 both disposed on the base. Both the inner core 21 and the outer periphery 22 can rotate relative to the base, making the lead-out of the substrate smoother. The base may also be provided with a torque drive to apply a set torque to the rotation direction of the inner core 21 and the outer periphery 22, thereby improving the stability of the substrate during wire feeding.

[0030] In this embodiment, multiple traction mechanisms 3 are sequentially arranged above multiple wire feeding mechanisms 2, thereby pulling the substrate out of the wire feeding mechanism 2 in a near-vertical direction. However, this invention does not limit the distribution position of the wire feeding traction mechanism 3, and it can also be located on the side of the wire feeding structure.

[0031] Reference Figure 3 As shown, the traction mechanism 3 includes a fixed plate 31, a straightening component, a tensioning component, and a guide wheel 34. The fixed plate 31 is fixedly mounted on the crossbeam of the wire feeding frame 1 by welding or bolting. The straightening component, the tensioning component, and the guide wheel 34 are all mounted on the fixed plate 31.

[0032] The straightening component includes two straightening rollers 32 arranged opposite each other on their circumferences. The two straightening rollers 32 can rotate towards each other, and a gap is formed between the two straightening rollers 32 for the substrate to pass through. The substrate passes through the gap and is squeezed on both sides to achieve the straightening effect.

[0033] The tensioning element includes a first tensioning roller 331 and a second tensioning roller 332 rotatably mounted on a fixed plate 31. Both the first tensioning roller 331 and the second tensioning roller 332 have grooves on their circumferences to facilitate the overlapping of the substrate. In this embodiment, two first tensioning rollers 331 are preferably arranged at a predetermined interval. After the substrate passes through the two straightening rollers 32, it successively overlaps the circumferences of the two first tensioning rollers 331. The second tensioning roller 332 is positioned between the two first tensioning rollers 331, and its circumference abuts against the substrate between the two first tensioning rollers 331, allowing the substrate to pass through the three rotating rollers. It is supported by three points of contact. The second tensioning wheel 332 is a detachable and multi-point fixed connection on the fixing plate 31. Specifically, the second tensioning wheel 332 is set on a bracket. The fixing plate 31 is provided with multiple connection holes for the bracket to be fixed by bolts. The connection holes are distributed along the direction perpendicular to the line connecting the two first tensioning wheels 331, so that the second tensioning wheel 332 can be installed at different intervals relative to the line connecting the two first tensioning wheels 331, thereby adjusting the tension applied by the second tensioning wheel 332 to the substrate, ensuring the tension of the substrate between the three rotating wheels, and realizing the stable feeding of the substrate.

[0034] The guide wheel 34 is rotatably mounted on the fixed plate 31. After the substrate is led out from the tensioning member, it overlaps the circumference of the guide wheel 34. Furthermore, a take-up wheel 4 is rotatably mounted on one side of the wire feeding frame 1. This side forms the wire output side of the wire feeding device. The substrate extends along the guide wheel 34 to the take-up wheel 4 and overlaps the circumference of the take-up wheel 4, thereby guiding the substrate out and ensuring stable output of the substrate to the next device.

[0035] In this preferred embodiment, the wire feeding frame 1 has a square frame structure, and multiple traction mechanisms 3 are arrayed on the top of the wire feeding frame 1. Multiple wire feeding mechanisms 2 are sequentially placed below the traction mechanisms 3. A rotating shaft 41 is provided on the wire output side of the wire feeding frame 1, and a take-up wheel 4 is rotatably passed through the rotating shaft 41. Multiple take-up wheels 4 are arranged along the axial direction of the rotating shaft 41. The number of take-up wheels 4 is set to be the same as the number of traction mechanisms 3, and they correspond sequentially to each traction mechanism 3, thereby realizing the unified collection of substrates on multiple traction mechanisms 3 on the wire feeding frame 1 to the wire output side.

[0036] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort should fall within the protection scope of this utility model.
