Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic module manufacturing equipment, and in particular to a busbar laser adhesive removal device. Background Technology
[0002] Busbars extending from the surface of photovoltaic modules are used to connect photovoltaic modules and concentrate the electrical energy generated in the modules to ensure the normal operation of the entire photovoltaic system. During the production of photovoltaic modules, if the adhesive process is not standardized, such as uneven adhesive coating thickness, excessive adhesive viscosity, or excessive adhesive application, adhesive overflow can easily occur, and the overflowing adhesive can easily stick to the surface of the busbars.
[0003] In the production process of photovoltaic modules, junction boxes also need to be installed. The bottom of the junction box has a strip-shaped hole that matches the busbar, allowing the upright busbar to pass through the junction box for installation. Then the busbar is flattened so that it connects with the conductor in the junction box. However, if there is glue on the surface of the busbar, it will cause the connection between the busbar and the junction box to be unstable, which will seriously affect the conductivity of the photovoltaic module.
[0004] Therefore, this application aims to provide a busbar laser adhesive removal device to solve the technical problems in the prior art. Utility Model Content

[0007] A busbar laser adhesive removal device, comprising a frame,
[0008] A conveying mechanism, mounted on a frame, is used to convey photovoltaic modules.
[0009] A correction mechanism, mounted on a frame, is used to correct the photovoltaic modules being transported by the conveyor assembly.

There are two laser emitting modules arranged side by side so that the lasers emitted by the two heads intersect. A Z-axis moving component is also provided at the bottom of the X-axis moving component. The Z-axis moving component is connected to the body and is used to drive the laser emitting module to move vertically up and down.

[0033] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0034] Reference Figure 1 and Figure 2The busbar laser adhesive removal equipment includes a frame 1, on which a conveying mechanism 2, a straightening mechanism 3, and a laser adhesive removal mechanism are installed. The conveying mechanism 2 is located at the bottom of the photovoltaic module 15 and is used to convey the photovoltaic module 15. The straightening mechanism 3 is used to straighten the photovoltaic module 15 conveyed by the conveying mechanism. A horizontal plate 14 is installed on the frame 1 along the X-axis. Three grippers 13 are installed on the horizontal plate 14. The grippers 13 are used to position the busbars on the photovoltaic module 15. The three grippers 13 are respectively used to correspond to the three sets of busbars installed on the photovoltaic module 15. The three grippers 13 are all slidably installed on the horizontal plate 14. Specifically, the grippers 13 slide along the length of the horizontal plate 14, so that the position of the grippers 13 can be adjusted according to the different intervals of the busbars on the photovoltaic module 15.
[0035] Reference Figure 2 and Figure 3 The laser adhesive removal mechanism includes a laser emitting module, a protective cover 10, an X-axis moving component 4, and a Z-axis moving component 7. The X-axis moving component 4 is used to drive the laser emitting module to move along the X-axis direction of the frame 1. The Z-axis moving component 7 is located at the bottom of the X-axis moving component 4 and is used to drive the laser emitting module to move up and down in the vertical direction. By setting the protective cover 10, the effect of the laser emitted by the laser emitting module on other positions can be reduced. The laser emitting module includes a body 6 and a head 5. The head 5 is rotatably mounted on the body 6. In this application, there are two laser emitting modules, which are arranged side by side. The protective cover is located outside the two laser emitting modules.
[0036] Reference Figure 4 The lasers emitted by the two laser heads 5 intersect, with one laser head 5 removing adhesive from side A of the busbar and the other laser head 5 removing adhesive from side B. A typical photovoltaic module 15 has two busbars 16, which are parallel to each other. The intersecting lasers can remove adhesive from both sides of the two busbars. Since the busbar, after being smoothed, mainly functions on the part that covers the junction box terminals after bending, i.e., the end of the busbar 16, this application primarily focuses on removing adhesive from this part.
[0037] Reference Figure 3The laser adhesive removal mechanism also includes an air blowing pipe 8 and a dust suction hood 9. The air outlet of the air blowing pipe 8 and the air suction port of the dust suction hood 9 both face the confluence strip, which is located between the air blowing pipe 8 and the dust suction hood 9. As a prior art, the air blowing pipe 8 is connected to an external power mechanism, and the air it blows out is natural wind. Its purpose is to reduce the temperature of the laser adhesive removal area. The dust suction is connected to an external power device, and its function is to remove the smoke and dust generated by the laser adhesive removal in a timely manner. The laser adhesive removal mechanism is also connected to a camera assembly. The protective cover 10 has a through hole for the camera assembly to pass through. The camera assembly includes a vision camera 11 and a light source 12. The light source 12 is used to illuminate the busbar to be removed, and the vision camera 11 is used to photograph the busbar. The vision camera 11 photographs the busbar before laser adhesive removal and uploads the photographed image to the processor and displays it on the monitor. Its function is to confirm the parallelism between the two busbars. If the angle between the busbars is too large or too small, a prompt will be issued, or the adhesive removal action of the busbar will be skipped directly. This is because when the angle between the busbars is too large or too small, the two laser emitting modules will have difficulty effectively removing adhesive from both sides of the busbar 16.
[0038] The conveying mechanism first transports the photovoltaic modules to the de-adhesive removal station. The alignment mechanism clamps both sides of the photovoltaic modules for alignment. Then, the X-axis moving component moves the laser emitting module above one of the busbars. The Z-axis moving component then moves the laser emitting module down and performs laser de-adhesive removal on both sides of the first busbar. After the laser de-adhesive removal is completed, the Z-axis moving component moves the laser emitting module up, and the X-axis moving component moves the laser emitting module to the next busbar to repeat the laser de-adhesive removal process until all the busbars on the photovoltaic modules have been de-adhesive removed. The laser de-adhesive removal mechanism quickly removes the adhesive adhering to the surface of the busbars, improving the stability of the connection between the busbars and the junction box.
[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
