[0040] This embodiment provides a battery string fixing device, which can fix the battery string and the glue film, improve production efficiency, and reduce production costs.

[0041] As Figures 1 - 4 shown, this battery string fixing device is used to fix the battery string 10 and the glue film 20. The battery string fixing device mainly includes a lifting assembly 100, a connecting assembly 200, and a spot welding assembly 300. Among them, the connecting assembly 200 is connected to the lifting assembly 100, and the lifting assembly 100 can drive the connecting assembly 200 to approach or move away from the battery string 10; an installation hole 210 is provided on the connecting assembly 200, and the spot welding assembly 300 is detachably connected to the installation hole 210.

[0042] Based on the above design, in this embodiment, the operator can lay the semi-finished product of the photovoltaic module flat on the working platform, and then start the lifting assembly 100, so that the lifting assembly 100 drives the connecting assembly 200 to descend until the spot welding assembly 300 on the connecting assembly 200 contacts the adhesive film 20 and the battery string 10. At this time, the spot welding assembly 300 can melt the adhesive film 20 and make the battery string 10 adhere to the melted adhesive film 20. That is, the adhesive film 20 is locally heated and melted under the heating action of the spot welding assembly 300 and then adheres to the battery string 10, thereby realizing the fixation of the adhesive film 20 and the battery string 10, and avoiding the relative displacement and deviation of the battery string 10 and the adhesive film 20 during the lamination process of the photovoltaic module. Through the settings of the lifting assembly 100, the connecting assembly 200 and the spot welding assembly 300, there is no need to fix the battery string 10 and the adhesive film 20 with positioning tape in the prior art, which not only saves time and effort, improves work efficiency, but also saves the cost of the positioning tape and reduces the production cost of the photovoltaic module.

[0043] In addition, the spot welding assembly 300 in this embodiment is detachably connected to the mounting hole 210, which is beneficial to the later maintenance and replacement of the spot welding assembly 300, improves work efficiency and saves costs.

[0044] It can be understood that the fixation of the battery string 10 and the adhesive film 20 by the battery string fixing device in this embodiment is pre-fixation, while the fixation of the battery string 10 and the adhesive film 20 in the subsequent lamination process is complete fixation.

[0045] It should be noted that the semi-finished product of the photovoltaic module laid flat on the working platform includes a front glass, a first adhesive film (front adhesive film), a battery string 10, and a second adhesive film (back adhesive film) laid in layers in sequence. The spot welding assembly 300 contacts the second adhesive film and melts it to adhere to the battery string 10.

[0046] Optionally, the battery string 10 in this embodiment can be a battery string 10 formed by connecting multiple single-sided solar cells to each other, or a battery string 10 formed by connecting multiple double-sided solar cells to each other, and both single-sided batteries and double-sided batteries can be set as half-size solar cells or full-size solar cells.

[0047] As Figure 4 shown, the bonding points 30 between each battery string 10 and the adhesive film 20 can be set to be multiple, and one or two solar cells can be arranged between two adjacent bonding points 30 in each battery string 10, so as to ensure that each solar cell can be adhesively connected to the adhesive film 20, thereby improving the stability and reliability of the pre-fixation between the battery string 10 and the adhesive film 20.

[0048] It can be understood that the lifting component 100 in this embodiment is a conventional component in the prior art, so the specific structure and working principle thereof will not be elaborated in this embodiment.

[0049] As Figures 1 - 3 shown, in this embodiment, the spot welding component 300 includes a heating contact 310 and a fixing member. The fixing member passes through the mounting hole 210 and is connected to the heating contact 310. The heating contact 310 is configured to heat and melt the adhesive film 20 so that the adhesive film 20 is bonded to the battery string 10. The detachable connection with the mounting hole 210 on the connection component 200 can be realized through the setting of the fixing member. Specifically, the fixing member includes a first nut 320, a second nut 330, and a stud 340. One end of the stud 340 passes through the mounting hole 210 and is connected to the heating contact 310. Both the first nut 320 and the second nut 330 are threadedly connected to the stud 340, and the first nut 320 and the second nut 330 respectively abut against opposite sides of the connection component 200. By threading both the first nut 320 and the second nut 330 onto the stud 340, the height of the stud 340 can be freely adjusted to be applicable to different types of battery strings 10, improving the flexibility and applicability. At the same time, the first nut 320 and the second nut 330 can be screwed and abutted against opposite sides of the connection component 200, thereby improving the stability and reliability of the connection between the fixing member and the mounting hole 210, and avoiding the phenomenon of shaking or instability of the spot welding component 300 during the process of spot welding the adhesive film 20.

[0050] Optionally, in some embodiments, the other end of the stud 340 and the first nut 320 can also be integrally formed, which reduces the steps of adjusting the first nut 320, simplifies the operation steps, saves time and effort, and improves work efficiency.

[0051] As Figures 1 - 2 shown, in this embodiment, the mounting hole 210 can be set as a strip-shaped hole. Through the setting of the strip-shaped hole, the movement of the spot welding component 300 in the strip-shaped hole can be realized. The operator can bond the adhesive film 20 to different positions of the solar cells in the battery string 10 according to actual needs, improving the flexibility and applicability. At the same time, it can also be adapted to different types or different versions of the battery string 10.

[0052] As Figures 1 - 2 shown, in this embodiment, the connection component 200 includes a first connecting rod 220 and a second connecting rod 230. The first connecting rod 220 is connected to the second connecting rod 230. The mounting hole 210 is provided on the first connecting rod 220, and the lifting component 100 is drivingly connected to the second connecting rod 230.

[0053] Further, at least one mounting hole 210 is provided on the first connecting rod 220. The mounting hole 210 extends along the length direction of the first connecting rod 220. That is, the extending direction of the strip-shaped hole is the same as the length direction of the first connecting rod 220.

[0054] Specifically, the first connecting rod 220 and the second connecting rod 230 are integrally formed. Moreover, both the first connecting rod 220 and the second connecting rod 230 are provided in multiple numbers, and the multiple first connecting rods 220 and the multiple second connecting rods 230 form a network structure; the length of the first connecting rod 220 is greater than the width of the battery string 10. That is to say, both ends of the first connecting rod 220 protrude from both sides in the width direction of the battery string 10. In this way, it is convenient for the lifting assembly 100 to be drivingly connected to the second connecting rod 230, and at the same time, it can ensure that the lifting assembly 100 will not have a phenomenon of frictional interference with the battery string 10, improving the reliability and stability of the battery string fixing device.

[0055] Optionally, both the first connecting rod 220 and the second connecting rod 230 are provided in numbers such as five, six, seven, or eight.

[0056] Optionally, in this embodiment, multiple dot ironing assemblies 300 are provided, and multiple dot ironing assemblies 300 are evenly spaced in each mounting hole 210. At the same time, the positions of the multiple dot ironing assemblies 300 in each mounting hole 210 can be adjusted back and forth in the mounting hole 210 to be applicable to bonding different positions of the battery string 10.

[0057] Optionally, one or more mounting holes 210 can be provided on each first connecting rod 220 in this embodiment.

[0058] Optionally, the cross-section of the heating contact 310 in this embodiment is a polygon, which can increase the bonding area between the battery string 10 and the adhesive film 20 as much as possible, improving the bonding stability and reliability. In addition, the operator can flexibly set the shape of the heating contact 310 according to actual needs. Exemplarily, the cross-section of the heating contact 310 can be set as a circle, an ellipse, an irregular shape, etc.

[0059] Optionally, the heating contact 310 in this embodiment includes an electric soldering iron. Specifically, the heating contact 310 in this embodiment can be set as an electric soldering iron to heat and melt the adhesive film 20 through the electric soldering iron, so that the adhesive film 20 is bonded to the battery string 10.

[0060] It can be understood that the electric soldering iron in this embodiment is a conventional component in the prior art. Therefore, the working principle and specific structure of the electric soldering iron are not described in detail in this embodiment.

[0061] As Figure 1As shown in the figure, this embodiment also provides a photovoltaic module processing device, which includes a conveying device 400 and the above-mentioned battery string fixing device. The conveying device 400 is used to convey the battery string 10 and the glue film 20 to the processing position, and the battery string fixing device is erected above the processing position. Specifically, the glue film 20 and the battery string 10 are placed on the conveying device 400, and the glue film 20 and the battery string 10 are pre-fixed by the battery string fixing device, and then the conveying device 400 is started to convey the semi-finished photovoltaic module after pre-fixing to the processing position in the laminator for the lamination process.

[0062] Since the photovoltaic module processing device has the above-mentioned battery string fixing device, the working efficiency of the photovoltaic module processing device is high and the production cost is low.
