Description

Technical Field

[0001] This utility model relates to the photovoltaic field, specifically to a device for separating solar cells from insulating paper. Background Technology

[0002] In the field of photovoltaic technology, back-contact solar cells, as an advanced solar cell design, require a unique manufacturing process that necessitates the precise deposition of a tunneling silicon oxide layer, an intrinsic polycrystalline silicon layer, and a phosphorus-doped polycrystalline silicon layer on the back of the silicon wafer, followed by oxygen annealing to form a mask layer. Due to the special manufacturing process of back-contact solar cells, in order to maintain the integrity of the cells during production, especially to protect their textured surfaces from any scratches and ensure photoelectric conversion efficiency, spacer paper must be placed between the cells. This spacer paper isolates adjacent cells, thereby protecting the special surface finish of the cells.

[0003] When processing solar cells, the separator paper needs to be separated from the cells. The current method of separation is usually done manually, which reduces the overall efficiency. Utility Model Content

[0004] To address the problems in the prior art, this application provides a device for separating battery cells and separator paper, which can automatically separate battery cells and separator paper, thereby improving production efficiency.

[0005] The technical solution is as follows:

[0007] Preferably, the transport components are arranged symmetrically.

[0008] Preferably, the conveying assembly includes a mounting plate, a suction cup is provided at the bottom of the mounting plate, and an air passage is provided inside the mounting plate. One end of the air passage is connected to the suction cup, and the other end is connected to a connecting pipe.

[0009] Preferably, the air knife assembly includes a bracket, a movable seat and a cylinder are provided on the bracket, the cylinder drives the movable seat to move up and down, the air knife is provided on the movable seat, and a connecting air pipe is provided on the air knife.

[0011] Preferably, the conveying component is connected to the vertical moving module via a connector; the connector is provided with reinforcing ribs.

[0012] Preferably, it also includes symmetrically arranged mounting brackets, on which the horizontally moving module is disposed.

[0013] In summary, using air knives to separate the battery cells and separator paper effectively improves separation efficiency. Simultaneously, employing color sensors to identify the battery cells and separator paper significantly improves handling accuracy, preventing the separator paper from being moved onto the conveyor line and causing unnecessary disruptions. Furthermore, the combination of horizontal and vertical movement modules enables precise movement of the handling components. Attached Figure Description

Detailed Implementation

[0019] To make the above-mentioned objects, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0020] like Figure 1As shown, the system includes a mounting frame 6, with a storage area 7 on one side. The storage area 7 stores the battery cells that need to be separated. The storage area 7 typically consists of several limiting rods, which are distributed around the battery cells according to their shape. A moving mechanism is mounted on the mounting frame 6, and a conveying assembly 1 is mounted on the moving mechanism. The conveying assembly 1 is located above the storage area 7, and a color sensor 2 is mounted on the conveying assembly 1, facing the storage area 7. Air knife assemblies 3 are also provided on both sides of the storage area 7. A separator paper recycling area and a battery cell conveying line are also provided. The installation positions of the separator paper recycling area and the battery cell conveying line need to be set according to process requirements, and they are usually located on different sides. It should be noted that the battery cells and separator paper are different colors. The color sensor 2 can identify the different colors, thus distinguishing whether the object being handled is a battery cell or separator paper, thereby preventing the battery cells from moving into the separator paper recycling area and preventing the separator paper from moving onto the battery cell conveying line.

[0021] Continue to refer to Figure 1 In this embodiment, a symmetrically arranged transport assembly 1 is used. Each transport assembly 1 employs two sets of suction cups, capable of simultaneously picking up two cells. Based on the design of the transport assembly 1, two sets of air knife assemblies 3 are also correspondingly arranged. This allows for the simultaneous operation of two battery cells, further improving overall efficiency.

[0022] Battery cells are placed in storage area 7. The air knife assembly 3 operates to separate the battery cells from the release liner. A moving mechanism controls a set of conveying components 1 to move directly above storage area 7. Then, the conveying components 1 descend to pick up the release liner, and then rise. A color sensor 2 identifies the release liner, and the moving mechanism controls the conveying components 1 to move the release liner to the release liner recycling area for storage. Another set of conveying components 1 can then be controlled by the moving mechanism to pick up the battery cells and move them to the conveyor line.

[0023] like Figure 2 As shown, the handling assembly 1 includes a mounting plate 101. Several suction cups 102 are provided at the bottom of the mounting plate 101. An air passage is provided inside the mounting plate 101, with the suction cups 102 and a connecting pipe 103 connected to both ends of the air passage, respectively. The connecting pipe 103 is connected to an external air source. The external air source provides suction, which is used to pick up the battery cells or insulating paper through the suction cups 102.

[0024] like Figure 3 and Figure 4As shown, the air knife assembly 3 includes a bracket 301, on which a cylinder 303 is vertically mounted. A movable seat 305 is mounted on the cylinder 303, and an air knife 302 is mounted on the movable seat 305. The cylinder 303 controls the movable seat 305 to rise and fall, adjusting the height of the air knife 302. A connecting air pipe 304 is mounted on the air knife 302. The connecting air pipe 304 is connected to an external air source. The cylinder 303 controls the movable seat 305 to rise and fall, causing the air outlet of the air knife 302 to move to the side of the battery cell. The air blown by the air knife 302 separates the battery cell from the separator paper.

[0025] like Figure 1 As shown, the moving mechanism includes a horizontal moving module 4 and a vertical moving module 5. It should be noted that the horizontal moving module 4 uses an electric slide table, and the vertical moving module 5 uses a lead screw module. The lead screw module is mounted on the slider of the electric slide table, enabling it to move on the electric slide table and control the lifting and lowering movement of the conveying assembly 1.

[0026] like Figure 1 As shown, the mounting plate 101 of the conveying assembly 1 is connected to the lead screw module via a connector 9; the connector 9 is provided with a reinforcing rib 8, which is triangular in shape, and its two sides are connected to the mounting plate 101 and the vertical moving module 5 respectively. The reinforcing rib 8 improves the overall strength. It also includes symmetrically arranged mounting frames 6, on which an electric slide is mounted.

[0027] In actual use, the electric slide control screw module moves, causing the transport component 1 to move directly above the battery cells. The air knife 302 separates the battery cells from the separator paper. The screw module then controls the transport component 1 to descend, and the suction cup 102 picks up the separator paper. The color sensor 2 identifies and determines whether the separator paper is being moved to the separator paper recycling area for collection. Another transport component 1 picks up the battery cells and moves them to the conveyor line. The above steps are repeated until all battery cells and separator paper are separated.

[0028] Other embodiments of the present invention will readily conceive of by those skilled in the art upon consideration of the specification and practice of the specific embodiments described herein. This application is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of the present invention and include common knowledge or customary techniques in the art not described herein. Furthermore, there may be minor differences in the wording of the names of certain components in different embodiments; these minor differences will not affect the understanding of the present invention by those skilled in the art.
