Description

Technical Field

[0001] This utility model relates to the field of solar panel manufacturing technology, specifically to an adsorption mechanism for solar cell strings. Background Technology

[0002] Before lamination in the solar panel production process, the assembled solar cell strings are inspected. If defects are detected in the solar cells or the solder joints between the solar cells and the solder strips, the defective strings need to be removed for manual repair or replacement. Currently, this is generally done by manually pulling the two ends of the string. However, solar cells are fragile, and the solder joints between the solar cells and the solder strips are also fragile. Therefore, the transfer needs to be slow and the pulling force needs to be carefully controlled, which not only affects efficiency but also requires a high level of skill. A search revealed a Chinese utility model patent with publication number CN205488178U, which discloses a solar cell string adsorption mechanism that can accurately and safely adsorb solar cells, ensuring the integrity of the solar cells, and facilitating subsequent maintenance; it saves time and labor and improves production efficiency. However, the above solution also has the following shortcomings: existing solar cell sizes come in various specifications, such as 125*125 and 150*150. The distance between the two horizontal vacuum suction cups in the above solution is fixed, so it can only be used for solar cell strings formed by welding solar cells of one specification (or similar sizes), which limits its application. Utility Model Content

[0003] The purpose of this invention is to provide an adsorption mechanism for solar cell strings to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an adsorption mechanism for a solar cell string, comprising a crossbeam made of aluminum alloy, two U-shaped handles fixedly installed on the upper side of the crossbeam, and a scissor-type telescopic fork. A round tube is installed at the hinge points on both sides of the telescopic fork, and a suction cup is installed at the lower end of the round tube. A pin and a positioning bolt are correspondingly provided at the hinge point in the middle of the telescopic fork. Only one positioning bolt is provided, located at the center point of the telescopic fork along its length. The positioning bolt is screwed into a screw hole at the bottom of the crossbeam. A cavity along the length is provided on the upper part of the crossbeam, and several branch connectors along the length are installed on both sides of the cavity. A flexible hose is connected between the branch connector and the upper end of the round tube. A main connector connecting to the cavity is fixedly installed at the end of the crossbeam. Elongated holes are provided on both sides of the screw hole at the bottom of the crossbeam. The pin is adapted to slide through the elongated holes, and the lower end of the pin is provided with an external thread and screwed with a nut.

[0005] Preferably, the upper sides of the elongated hole are provided with guide grooves larger than its width, and the upper part of the pin is provided with a square slider, which is adapted to slide and connect with the guide groove.

[0006] Preferably, a Z-shaped support frame is fixedly installed at both ends of the crossbeam, and a vertically sliding round rod is installed on both sides of the support frame. A washer is welded to the lower end of the round rod, and a spring is connected between the upper side of the washer and the bottom of the support frame.

[0007] Compared with the prior art, the beneficial effects of this utility model are: the suction cup is installed on the hinge points on both sides of the telescopic fork, and the extension or shortening of the telescopic fork is specifically reflected in the change of the distance between two adjacent hinge points, which can adapt to battery strings formed by connecting battery cells of different specifications and sizes, and has good compatibility and is convenient to use.

[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0011] Please see Figure 1-4This utility model provides a technical solution: an adsorption mechanism for solar cell strings, including an aluminum alloy crossbeam 1. Two U-shaped handles 2 are fixedly installed on the upper side of the crossbeam 1 for the operator to grip and lift. Z-shaped support frames 3 are fixedly installed at both ends of the crossbeam 1. Vertically sliding round rods 4 are installed on both sides of the support frames 3. Washers 6 are welded to the lower ends of the round rods 4. A spring connects the upper side of the washer 6 to the bottom of the support frame 3. The washer 6 contacts the table surface to support the device. It also includes a scissor-type telescopic fork 5, which is made of several scissor arms hinged together. The telescopic fork 5 has round tubes installed at the hinge points on both sides, and suction cups 8 are installed at the lower end of the round tubes. The telescopic fork 5 has a pin 9 and a positioning bolt 10 at the hinge point (i.e., the intersection point) in the middle. There is only one positioning bolt 10, which is located at the center point of the telescopic fork 5 in the length direction. The positioning bolt 10 is screwed to the screw hole 11 at the bottom of the crossbeam 1. The purpose is to realize the telescopic fork 5 to extend and retract to both sides, while the distance between the two adjacent sets of suction cups 8 is adjusted synchronously.

[0012] The upper part of the crossbeam 1 has a cavity 13 along its length. Several branch connectors along the length are installed on both sides of the cavity 13. A flexible hose 7 (with a certain length redundancy) is connected between the branch connectors and the upper end of the circular pipe. A main connector connecting to the cavity 13 is fixedly installed at the end of the crossbeam 1. The main connector is connected to a vacuum generator to achieve negative pressure adsorption. The bottom of the crossbeam 1 has elongated holes 12 on both sides of the screw hole 11. The pin 9 is adapted to slide and connect with the elongated holes 12. The lower end of the pin 9 has an external thread and is screwed with a nut. The nut is used to prevent the scissor arms from falling off. When the nut is tightened, the angle of the two crossed scissor arms can be fixed. The upper sides of the elongated holes 12 have guide grooves 14 that are wider than their width. The guide grooves 14 are composed of two parallel ribs. The upper part of the pin 9 has a square slider. The slider is adapted to slide and connects with the guide grooves 14. The slider is constrained by the guide grooves 14 and cannot rotate.

[0013] Working Principle: This mechanism utilizes two suction cups 8 on opposite sides of the crossbeam 1 to adsorb each battery cell in the battery string. To accommodate battery cells of different sizes, the distance between adjacent suction cups 8 can be adjusted. Specifically, the midpoint of the telescopic fork 5 is fixed by the positioning bolt 10. By loosening the nut at the lower end of the pin 9, pushing or pulling the end of the telescopic fork 5 can adjust its extension length and simultaneously adjust the distance between adjacent suction cups 8. The round rod 4 and spring form elastic support legs to prevent the overall weight from pressing on them during battery adsorption, thus preventing excessive pressure on the battery cells from the suction cups 8 and causing them to break.

[0014] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
