Abstract
Description
Technical Field
[0001] The utility model relates to the field of photovoltaic component production auxiliary equipment, in particular to a photovoltaic component cutting mechanism. Background Art
[0002] In the production process of modern solar photovoltaic modules, the lamination process is a crucial step, which involves bonding the solar cells to the glass and backplane materials through EVA (ethylene-vinyl acetate copolymer) adhesive film under certain heat and pressure to form a solid photovoltaic panel. However, in this process, excess lamination residue will be generated at the edge of the module due to overflow of the lamination material or incomplete bonding of the edges.
[0003] In order to ensure that the appearance and performance of photovoltaic modules meet the standards, these edge residues need to be cleaned. The commonly used method is to use an edge trimmer for mechanical cutting. The traditional edge trimmer uses a blade pull-and-push working principle to cut off the excess residue. However, this traditional edge trimming method has some significant problems. The first is the shape of the waste generated during the edge trimming process. Since the blade is directly cut, the removed residues are usually in the shape of long strips. They are prone to flying when being cut, and may then be randomly scattered in a wide area. This not only increases the difficulty of cleaning work, but may also pollute the environment around the production line, affecting production efficiency and workshop cleanliness.
[0004] Another problem is that the effect of traditional edge trimming machines is not perfect. Especially at the four corners of the laminated module glass, these areas are often difficult to be thoroughly cleaned due to the special location and shape of the corners, resulting in residues that cannot be completely removed. Therefore, after the machine trimming, workers are usually required to manually clean up to remove these residues and ensure the quality and appearance of the photovoltaic modules. This not only increases labor intensity, but also reduces the degree of automation and efficiency of production.
[0005] Therefore, it is necessary to design a photovoltaic module cutting mechanism to solve the above problems. Utility Model Content
[0006] The utility model aims to provide a photovoltaic module cutting mechanism to improve the quality of edge cutting, reduce subsequent cleaning work, reduce labor costs and safety risks, and improve the automation level and efficiency of photovoltaic module production.
[0007] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a photovoltaic module cutting mechanism, used for trimming laminated parts, which includes a driving assembly, a roller assembly and a cutting knife assembly arranged on the driving assembly, the roller assembly and the cutting knife assembly are arranged in sequence front and back along the driving direction of the driving assembly, the roller assembly includes a bracket, two rollers elastically arranged on the bracket, the two rollers are arranged front and back, the roller includes a mounting shaft, a roller and a knife group arranged on the roller, the axes of the two rollers are parallel to each other, and the roller located on the front side protrudes in the left and right direction from the roller located on the rear side.
[0008] As a further improved technical solution of the utility model, the angle between the two rollers relative to the elastic direction of the bracket is ≤90°.
[0009] As a further improved technical solution of the utility model, the bracket has two cylinders, and the hob assembly also includes an elastic member, which includes a rod portion vertically connected to the mounting shaft, a spring sleeved on the outside of the rod portion, a limit pin perpendicular to the rod portion, and a limit portion cooperating with the limit pin, the spring abuts between the mounting shaft and the limit portion, the limit portion is provided with a strip groove in the same direction as the spring expansion and contraction direction, the limit pin slides in cooperation with the strip groove, and the limit portion is fixed in the cylinder.
[0010] As a further improved technical solution of the utility model, a plurality of through holes are opened on the rod portion along its radial direction, and the limit pin is passed through one of the through holes and cooperates with the through hole thread.
[0011] As a further improved technical solution of the utility model, the limiting part is tubular, the number of the strip grooves is 2, and they are symmetrically opened along the axial direction of the limiting part, and both ends of the limiting pin protrude out of the through hole and respectively cooperate with the two strip grooves.
[0012] As a further improved technical solution of the utility model, the cutter group on the hob is arranged tilted.
[0013] As a further improved technical solution of the utility model, the setting direction of the cutter group of the hob located on the front side forms an angle of 45° with the forward direction of the hob.
[0014] As a further improved technical solution of the utility model, the setting direction of the cutter group of the hob located at the rear side forms an angle of -45° with the forward direction of the hob.
[0015] As a further improved technical solution of the utility model, a brush for cleaning the edge of the laminate is also provided on one side of the hob.
[0016] It can be seen from the above technical scheme that the photovoltaic module cutting mechanism of the utility model uses two rollers arranged in front and back, and the front roller protrudes from the rear roller. When the roller assembly moves to the four corners of the component, the front roller is finely trimmed by the rear roller under the action of elasticity, which enhances the adaptability to different laminates. The new technical scheme can more thoroughly remove the residues at the four corners of the component glass, reduce the manual cleaning work of these areas, improve the degree of automation and save human resources; the shape of the removed waste is controlled and no longer in the shape of long strips, which reduces the risk of flying and hanging on the one hand, thereby reducing potential safety threats and improving the safety of the working environment. On the other hand, it reduces the scattering range of waste, making it easier to collect and clean up waste, thereby reducing the cleaning workload at the production site. Due to the improvement of edge cutting quality and cleaning efficiency, the production process of the entire photovoltaic module will be smoother, reducing rework or quality problems caused by incomplete edge cutting, thereby improving the overall efficiency of the production line.

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.
[0021] The utility model provides a photovoltaic module cutting mechanism for cutting edges of a laminate 100. Figure 1 As shown, the photovoltaic module cutting mechanism includes a driving assembly 10, a roller assembly 20 and a cutting knife assembly 30 arranged on the driving assembly 10, and the roller assembly 20 and the cutting knife assembly 30 are arranged in sequence along the driving direction of the driving assembly 10. In the trimming process, the roller assembly 20 located in the front first performs a preliminary longitudinal cutting (i.e., the left-right direction as shown in the figure) on the edge of the laminate, and further, the cutting knife assembly 30 performs a transverse cutting (i.e., the front-back direction as shown in the figure) to avoid the waste generated by cutting in the form of long strips.
[0022] For details, please refer to Figure 2As shown, the roller cutter assembly 20 includes a bracket 21, two roller cutters 22 elastically arranged on the bracket 21, and the two roller cutters 22 are arranged front and back. The roller cutter 22 includes a mounting shaft 221, a roller 222, and a knife group 223 arranged on the roller 222. The axes of the two rollers 222 are parallel to each other. The roller cutter 22 located at the front side protrudes from the roller cutter 22 located at the rear side in the left-right direction, that is, the roller cutter 22 at the front side is closer to the edge of the laminate. When the rear roller cutter 22 contacts the edge of the laminate 100, the front roller cutter 22 abuts against the edge of the laminate 100 and is in a compressed state.
[0023] A brush 24 for cleaning the edge of the laminate 100 is also provided on one side of the hob 22. The position and number of the brush 24 can be selected and designed according to actual needs and are not limited here.
[0024] The support 21 has two cylinders 211 and 212. Figure 3 As shown, the two hobs 22 are connected to the two cylinders 211 and 212 respectively through the elastic member 23. The elastic member 23 includes a rod 231, a spring 232, a stop pin 233 and a stop portion 234. The rod 231 is vertically connected to the mounting shaft 221, and a plurality of through holes 2311 are provided on the rod 231 along its radial direction. The stop pin 233 is passed through one of the through holes 2311 and is fixed with the through hole 2311 by threading, that is, the stop pin 233 is perpendicular to the rod 231. In actual use, the stop pin 233 can be installed in conjunction with different through holes 2311, and the position of the stop pin can be adjusted, so that the elastic force of the elastic member 23 is different to meet the needs of different products and scenarios.
[0025] The spring 232 is sleeved on the outside of the rod 231, and the spring 232 abuts between the mounting shaft 221 and the limiting portion 234. The limiting portion 234 is preferably tubular, and is provided with a strip groove 2341 in the same direction of expansion and contraction as the spring 232. The number of the strip grooves 2341 is two, and they are symmetrically opened along the axial direction of the limiting portion 234. Both ends of the limiting pin 233 protrude out of the through hole 2311 and slide in cooperation with the two strip grooves 2341 respectively. The limiting portion 234 is fixed in the cylinders 211 and 212. In this embodiment, the angle between the elastic directions of the two hobs 22 relative to the bracket 21 is ≤90°, that is, the angle between the expansion and contraction directions of the two springs 232 is ≤90°.
[0026] The knife set 223 on the hob 22 is tilted, that is, the setting direction of the knife set 223 forms a certain angle with the forward direction of the hob 22. Preferably, the setting direction of the knife set of the hob located on the front side forms a 45° angle with the forward direction of the hob 22, and the setting direction of the knife set of the hob located on the rear side forms a -45° angle with the forward direction of the hob 22. With such a setting, the cuts made by the front and rear hobs 22 on the edge of the laminate 100 are perpendicular to each other, and after further transverse cutting by the cutting knife assembly 30, the waste generated is small, so that the edge rubber strip can be removed without damaging the side edge of the glass, and the edge rubber strip can be granulated and fall down, which is convenient for cleaning and collection, and there is no risk of waste hanging on the edge interfering with other equipment.
