Description

Technical Field

[0001] This utility model relates to the field of battery cell coating, specifically a conveyor belt with a straightening function. Background Technology

[0002] Solar cells are the basic building blocks of solar cells, primarily used to convert light energy into electrical energy. They can be categorized into solar cell sheets and metal-based solar cells. Solar cell sheets mainly use semiconductor materials such as monocrystalline silicon and polycrystalline silicon, and are widely used in photovoltaic power generation systems.

[0003] In the production of photovoltaic cells, during the coating process, it is necessary to fix the solder ribbons on the surface of the cell with a thin film. Usually, the solder ribbons are first laid on the surface of the cell, and then the surface of the thin film is covered over the entire surface of the cell and the solder ribbons. By heating the thin film, the thin film and the solder ribbons are pre-fixed on the surface, thus achieving the coating.

[0004] Before the coating process, the solar cells need to be transported to a designated processing position. During transport, the solar cells may tilt. When tilted solar cells are processed, their quality will be significantly reduced, greatly lowering the product yield. Therefore, it is necessary to straighten the solar cells. Utility Model Content

[0005] To address the problems in the prior art, this application provides a conveyor belt with a straightening function, which can straighten the battery cells on the conveyor belt.

[0006] The technical solution is as follows: A conveyor belt with a straightening function includes a conveyor belt on which solar cells are conveyed. An angle rotation mechanism, a preliminary straightening mechanism, and a bidirectional straightening mechanism are sequentially arranged on the conveyor belt along the conveying direction of the solar cells. The bidirectional straightening mechanism includes a drive mechanism located below the conveyor belt. A support is provided on the drive mechanism. A bidirectional straightening device and a straightening block are provided on both sides of the conveyor belt. The bidirectional straightening device includes a first roller and a second roller, which straighten the adjacent two sides of the solar cells respectively.

[0007] Specifically, the bidirectional alignment device further includes a first mounting base and a second mounting base disposed on the bracket. The first mounting base and the second mounting base are disposed perpendicular to each other and are respectively located on the outer sides of adjacent sides of the battery cell. The first roller and the second roller are respectively disposed on the first mounting base and the second mounting base.

[0008] Specifically, the second mounting base is provided with an adjusting component for adjusting the first roller.

[0009] Specifically, the drive mechanism includes a transverse linear module, which is disposed below the conveyor belt and moves in the same direction as the battery cell conveying direction. A longitudinal linear module perpendicular to the transverse linear module is disposed on the transverse linear module, and the bracket is disposed on the longitudinal linear module.

[0010] Preferably, an angle rotation mechanism is provided on the conveyor belt at the first end of the battery cell conveying direction. The angle rotation mechanism includes a fixed seat provided on the side of the conveyor belt, a motor and a rotating shaft are provided on the fixed seat, the top of the rotating shaft is connected to the output end of the motor via a belt, and a suction cup is provided at the bottom of the shaft, which is located above the conveyor belt.

[0011] Preferably, the preliminary straightening mechanism is symmetrically arranged on both sides of the conveyor belt; the preliminary straightening mechanism includes a mounting plate arranged on the side of the conveyor belt, a cylinder is arranged on the mounting plate, a mounting block is arranged at the output end of the cylinder, and a third roller is arranged on the mounting block.

[0012] Preferably, a recovery disc is provided at the tail end of the conveyor belt in the conveying direction.

[0013] In summary, by sequentially installing an angle rotation mechanism, a preliminary alignment mechanism, and a bidirectional alignment mechanism on the conveyor belt, the solar cells on the conveyor belt can be rotated, positioned, initially aligned, and finally aligned bidirectionally. This two-stage alignment effectively improves the alignment effect of the solar cells. Specifically, the bidirectional alignment mechanism, including the bidirectional alignment device and the alignment block, uses the first and second rollers in the bidirectional alignment device, in conjunction with the movement of the alignment block, to perform bidirectional alignment of the solar cells in the X and Y directions. This further enhances the alignment effect based on the preliminary alignment, meeting the requirements of subsequent coating processes. Attached Figure Description

[0016] 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.

[0017] like Figure 1 As shown, the system includes a conveyor belt 1, which transports solar cells. Along the direction of solar cell transport, the conveyor belt 1 is sequentially equipped with an angle rotation mechanism 4, a preliminary alignment mechanism 3, and a bidirectional alignment mechanism 2. The solar cells are placed on the conveyor belt 1 and sequentially undergo angle calibration by the angle rotation mechanism 4, unidirectional alignment by the preliminary alignment mechanism 3, and bidirectional alignment by the bidirectional alignment mechanism 2, ultimately achieving the initial alignment of the solar cells. It should be noted that the conveyor belt is a continuous material conveying device based on the principle of friction transmission, widely used in industrial production, logistics transportation, and other fields, and is a commonly used transmission device. Its core working principle is that a motor drives a drum to rotate, using friction to move the circular conveyor belt, thereby achieving directional material transport. Its core components include a drive unit and a conveyor belt. The drive unit consists of a motor and a reducer, providing power and adjusting the conveying speed. The conveyor belt is made of rubber.

[0018] like Figure 2As shown, the bidirectional alignment mechanism 2 includes a drive mechanism, which comprises a transverse linear module 201 and a longitudinal linear module 202. The transverse linear module 201 is installed below the conveyor belt 1, and its installation direction is consistent with the arrangement direction of the conveyor belt 1; that is, the direction of movement of the slider on the transverse linear module 201 is consistent with the conveying direction of the conveyor belt 1. A longitudinal linear module 202 is provided on the transverse linear module 201, and the longitudinal linear module 202 is vertically installed on the slider of the transverse linear module 201; that is, the direction of movement of the slider on the longitudinal linear module 202 is perpendicular to the direction of movement of the slider on the transverse linear module 201. It should be noted that linear modules have been widely used in various types of equipment. Through the combination of various units, linear and curvilinear motion of the load can be achieved, making the automation of light loads more flexible and the positioning more precise. Currently widely used linear modules can be divided into three types: synchronous belt type, ball screw type, and linear motor type. The transverse linear module 201 adopts a linear motor type linear module to realize the movement of the longitudinal linear module 202. The longitudinal linear module 202 adopts a synchronous belt type linear module. The working principle of the synchronous belt type is as follows: a ring belt is installed on the drive shafts on both sides of the linear module, with one or more sliders fixed on the belt to increase the workpiece of the equipment. When there is input, the sliders move by driving the belt. The longitudinal linear module 202 is equipped with two sliders, which are respectively installed on different sides of the ring belt, that is, connected to the upper and lower ends of the ring belt respectively. When the ring belt rotates, the two sliders can move relative to each other simultaneously.

[0019] like Figure 2 As shown, the support 204 includes two independent supports, which are respectively mounted on two sliders of the longitudinal linear module 202. A bidirectional alignment device and an alignment block 203 are respectively mounted on the two independent supports of the support 204, such that the bidirectional alignment device and the alignment block 203 are located on opposite sides of the conveyor belt 1. The longitudinal linear module 202 drives the two independent supports to move relative to each other simultaneously, that is, to move simultaneously toward or away from the conveyor belt 1, thereby controlling the bidirectional alignment device and the alignment block 203 to align the battery cells on the conveyor belt 1. The alignment block 203 includes a base and a roller fixed to the independent support.

[0020] like Figure 2 and Figure 3As shown, the bidirectional alignment device includes a first mounting base 205 and a second mounting base 206 fixed on a bracket 204. The first mounting base 205 and the second mounting base 206 are arranged perpendicularly to each other, that is, the second mounting base 206 is located at one end of the first mounting base 205 and protrudes from the first mounting base 205. A first roller 207 and a second roller 208 are respectively arranged on the first mounting base 205 and the second mounting base 206, corresponding to the adjacent two sides of the battery cell, that is, one side and one end of the battery cell, for example, the right side and the first end of the battery cell. The mutually perpendicular first roller 207 and the second roller 208 contact and move with the adjacent two sides of the battery cell, and the first roller 207 is coordinated with the roller on the alignment block 203, thereby performing bidirectional alignment of the battery cell in the XY direction. Note that the direction of battery cell conveying is set as the X direction, and the direction perpendicular to it is set as the Y direction.

[0021] like Figure 3 As shown, the first mounting base 205 includes a lower base and an upper base, which are not connected to each other due to a gap. An adjusting component 209 is installed on the side of the lower base. The adjusting component 209 includes a screw and a nut seat, with the screw and nut seat connected by threads. The nut seat is connected to the lower base, and the screw is connected to the upper base. The first roller 207 is mounted on the upper base. By rotating the screw, the relative position of the first roller 207 and the solar cell can be adjusted. Since the second mounting base 206 is fixed, the position of the first roller 207 can be adjusted by rotating the screw during the initial equipment commissioning, thus enabling initial commissioning according to solar cells of different sizes.

[0022] When the solar cell moves to the bidirectional alignment mechanism 2, the longitudinal linear module 202 drives two independent supports to move simultaneously toward the solar cell. The rollers on the first roller 207 and the alignment block 203 push and align the two sides of the solar cell. The transverse linear module 201 drives the longitudinal linear module 202 to move, causing the second roller 208 to push and align the first end of the solar cell, thereby performing bidirectional alignment of the solar cell in the XY direction. In this embodiment, multiple sets of bidirectional alignment devices and alignment blocks 203 are used. The solar cell is transported to each set of bidirectional alignment devices and alignment blocks 203, which can simultaneously drive the bidirectional alignment devices and alignment blocks 203 to align multiple solar cells.

[0023] like Figure 4As shown, the preliminary alignment mechanism 3 includes a mounting plate 301, which is installed on both sides of the conveyor belt 1. A cylinder 302 is fixed to the mounting plate 301. Then, a mounting block 303 is fixed to the output end of the cylinder 302, i.e., the piston rod end faces the conveyor belt 1 and the mounting block 303 is positioned thereon. The mounting block 303 is elongated, and its length is set according to the side length of the battery cell. Several third rollers 304 are spaced apart on the mounting block 303. The figure shows four third rollers 304 providing more contact with the sides of the battery cell. The cylinders 302 on both sides of the conveyor belt 1 simultaneously drive the mounting blocks 303 to move towards the conveyor belt 1, and the third rollers 304 push the sides of the battery cell, achieving alignment of the battery cell in the Y direction.

[0024] To facilitate subsequent positioning of the solar cells, marking points are usually set on them, and one corner of the cell is typically beveled. During the initial processing of the solar cells, the bevel is usually rotated to the same position. For example... Figure 5 As shown, the angle rotation mechanism 4 includes a fixed base 401 mounted on the side of the conveyor belt 1. A motor 402 and a rotating shaft 404 are mounted on the fixed base 401. The rotating shaft 404 passes through the fixed base 401, with its two ends positioned above and below the fixed base 401, respectively. The upper end of the rotating shaft 404 is connected to the output end of the motor 402 via a belt 403, and its lower end is connected to a suction cup 405. The suction cup 405 includes an integrated plate connected to the lower end of the rotating shaft 404 and a suction cup mounted on the integrated plate. A channel is formed within the integrated plate, and the suction cup communicates with the channel. An external air source is connected to the channel to generate suction, enabling the suction cup 405 to pick up the battery cells. The distance between the suction cup 405 and the upper surface of the battery cell is set between 1-2 mm, allowing the suction cup 405 to pick up the battery cell without lowering itself. The battery cell is conveyed by the conveyor belt 1 to the area below the suction cup 405. The suction cup 405 picks up the battery cell, the motor 402 works, drives the belt 403 to rotate, and then drives the rotating shaft 404 to rotate, so that the inclined edge on the battery cell rotates to the designated position.

[0025] like Figure 1 As shown, it also includes a recycling tray 5 and a camera 6. The recycling tray 5 is installed at the end of the conveyor belt 1 and is used to collect unaligned battery cells. The camera 6 is located above the conveyor belt 1 at the bidirectional alignment mechanism 2 and is used to photograph the battery cells at that location to determine whether the alignment is complete. The determination criteria are whether the battery cell is tilted; if it is tilted, the alignment is incomplete. Also, whether the tilted edge is located at a designated position; if it is not at the designated position, the alignment is considered incomplete.

[0026] The operating procedure is as follows: The battery cell is placed on conveyor belt 1 for transport. When the battery cell moves below suction cup 405, suction cup 405 picks it up. Motor 402 drives suction cup 405 to rotate the battery cell to a designated position. Then, suction cup 405 releases the battery cell, allowing it to fall back onto conveyor belt 1. Next, the battery cell is transported to the preliminary alignment mechanism 3. Simultaneously, cylinders 302 on both sides drive the third roller 304 on mounting block 303 to push the battery cell on both sides, achieving alignment in the Y direction. Then, when the battery cell is transported to the bidirectional alignment mechanism 2, the first roller 207, the second roller 208, and the alignment block 203 work together to align the battery cell bidirectionally. After alignment, camera 6 captures an image of the battery cell to determine if alignment is complete. If alignment is incomplete, the bidirectional alignment mechanism 2 re-aligns the battery cell until camera 6 determines that alignment is complete. If the battery cells cannot be straightened, they will be transferred to the recycling tray 5, or an alarm will be triggered for workers to handle the situation.
