Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment, specifically a solar cell feeding device. Background Technology

[0002] In the field of photovoltaic technology, back-contact solar cells (BC cells) are an advanced solar cell design. Their unique manufacturing process requires 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 a 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. The spacer paper isolates adjacent cells, thereby protecting the special surface finish of the cells.

[0003] When processing BC batteries, it is necessary to separate the batteries from the separator paper before transporting the battery cells to a designated location for further processing. Therefore, a device needs to be designed that can separate the battery cells from the separator paper and move both the battery cells and the separator paper to the designated location. Utility Model Content

[0004] To address the problems in the prior art, this application provides a battery cell feeding device that can separate the initial battery cell from the separator paper and move the separator paper and battery cell to a designated position.

[0005] The technical solution is as follows:

[0006] A battery cell feeding device includes a conveying mechanism for conveying battery cells and separator paper; a storage area located below the conveying mechanism for storing initial battery cells; a recycling area and a conveyor line located on both sides of the storage area for storing separator paper and conveying battery cells, respectively; a straightening mechanism located on the conveyor line for straightening the battery cells; and an air knife mechanism located on the storage area for separating the initial battery cells from the separator paper.

[0007] Specifically, the conveying mechanism includes a mounting frame, on which a horizontal moving module is horizontally arranged, and on which a vertical moving module is arranged, and on which a conveying component for conveying battery cells and release paper is connected via a connector, and on which a color sensor is arranged.

[0008] Specifically, the conveying assembly includes a mounting plate, a suction cup at the bottom of the mounting plate, and an air passage 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] Specifically, the air knife mechanism includes a bracket set on the storage area, a movable seat and a cylinder set on the bracket, the cylinder driving the movable seat to move up and down, the movable seat being equipped with an air knife, and the air knife being equipped with a connecting air pipe.

[0010] Specifically, the alignment mechanism includes an alignment frame with a track. Sliding movable blocks are symmetrically arranged at intervals on the track. Limiting plates are provided on the movable blocks, and limiting wheels are provided on the limiting plates. A driving wheel and a driven wheel are respectively provided at both ends of the alignment frame. A transmission belt is wound around the driving wheel and the driven wheel. A driving device for driving the driving wheel to rotate is provided at the bottom of the alignment frame. The symmetrically arranged limiting plates are respectively connected to both sides of the transmission belt.

[0011] Specifically, it also includes a clamping plate that clamps the transmission belt, and the top of the clamping plate is connected to the limiting plate.

[0012] Specifically, there are at least two limiting wheels, which are respectively located at the head, middle and tail of the limiting plate.

[0013] Specifically, limit blocks are provided at both ends of the alignment frame, located outside the driving wheel and outside the driven wheel.

[0014] Preferably, the conveying mechanism is equipped with a camera, which faces the conveyor line.

[0015] Specifically, the recycling area includes a surrounding baffle, the top of which is provided with an outwardly inclined guide plate.

[0016] In summary, separating the battery cells and separator paper using an air knife and simultaneously moving both via two sets of conveying components allows for separate transport and recycling of the cells and separator paper, significantly improving the efficiency of initial battery cell pretreatment. Furthermore, a alignment mechanism on the conveyor line aligns the cells, ensuring they are transported to the next processing unit at a specified angle, thus improving the quality of subsequent processing. Additionally, color sensors on the conveying components further identify the transported items, preventing separator paper from being moved onto the conveyor line and improving the accuracy of cell and separator paper movement.

[0026] 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.

[0027] like Figure 1As shown, the system includes a conveying mechanism 1, with a storage area 2 installed below it. Initial battery cells are placed in the storage area 2. The storage area 2 typically consists of several surrounding rods 201, which are arranged around the initial battery cells according to their shape. The initial battery cells are those containing release paper and are unprocessed. A conveyor line 4 and a recycling area 3 are installed on both sides of the storage area 2. The tail end of the conveyor line 4 is connected to equipment for subsequent processing. A straightening mechanism 5 is installed on the conveyor line 4, as shown in the figure, near the head of the conveyor line 4. An air knife mechanism 6 is installed on both sides of the storage area 2, as shown in the figure. The air knife mechanism 6 can simultaneously blow air onto both sides of the battery cells, allowing the release paper to detach more smoothly from the battery cells.

[0028] The air knife mechanism 6 operates, blowing air onto the initial battery cells in storage area 2 to separate the battery cells from the separator paper. The conveying mechanism 1 moves the battery cells and separator paper to the conveyor line 4 and the recycling area 3, respectively. The recycling area 3 collects the separator paper, and the conveyor line 4 transports the battery cells to the subsequent processing equipment. When the conveyor line 4 transports the battery cells to the straightening mechanism 5, the straightening mechanism 5 straightens the battery cells, adjusting them to the correct angle for subsequent processing.

[0029] like Figure 2 As shown, the conveying mechanism 1 includes a mounting frame 106, on which a horizontal moving module 104 is mounted. A vertical moving module 105 is mounted on the horizontal moving module 104, and the horizontal moving module 104 drives the vertical moving module 105 to move horizontally. Here, the horizontal moving module 104 is an electric slide table, and the vertical moving module 105 is a lead screw module, which is mounted on the slider of the electric slide table, allowing the lead screw module to move on the electric slide table. The conveying assembly 101 is mounted on the vertical moving module 105 via a connector 103. Through the cooperation of the vertical moving module 105 and the horizontal moving module 104, the vertical and horizontal movement of the conveying assembly 101 can be realized. A color sensor 102 is mounted on the conveying assembly 101. Since the battery cells and the separator paper are different colors, the color sensor 102 can identify the different colors, thus identifying whether the object being grasped is a battery cell or separator paper, preventing the battery cells and separator paper from being moved to the wrong position.

[0030] The quantity of the handling components 101 can be set according to requirements, such as... Figure 2As shown in the figure, two sets of conveying components 101 are used for conveying, which can simultaneously move the two initial battery cells and the separator paper in sequence. Compared with a single set of conveying components 101, this greatly improves the conveying efficiency. Similarly, the number of vertical moving modules 105 can also be set according to requirements, such as... Figure 2 As shown in the diagram, two sets of vertical moving modules 105 are arranged. One set of vertical moving modules 105, closer to the conveyor line 4, transports the battery cells, while the other set, closer to the recycling area 3, transports the separator paper. One set of vertical moving modules 105 must wait for the separator paper to be transported before it can transport the battery cells. The two sets of vertical moving modules 105 can transport the separator paper and battery cells separately, without waiting for the separator paper to be transported, further improving overall efficiency. By setting two sets of vertical moving modules 105 and two sets of transport components 101, the original efficiency can be increased by 4 times.

[0031] After the battery cells and separator paper are separated, a set of vertical moving modules 105 moves horizontally above the storage area 2. This vertical moving module 105 controls the conveying assembly 101 to descend and pick up the separator paper. A color sensor 102 determines whether the picked-up item is separator paper based on color difference and moves the separator paper to the recycling area 3. Simultaneously, another set of vertical moving modules 105 moves horizontally above the storage area 2. This vertical moving module 105 controls the conveying assembly 101 to descend and pick up the battery cells. A color sensor 102 determines whether the picked-up item is a battery cell based on color difference and moves the battery cell to the conveyor line 4.

[0032] like Figure 3 As shown, the handling assembly 101 includes a mounting plate 1011. Several suction cups 1012 are provided at the bottom of the mounting plate 1011. An air passage is provided inside the mounting plate 1011, with the suction cups 1012 and a connecting pipe 1013 connected to both ends of the air passage. The connecting pipe 1013 is connected to an external air source. The external air source provides suction, which is used by the suction cups 1012 to pick up the battery cells or insulating paper.

[0033] like Figure 4 and Figure 5 As shown, the air knife mechanism 6 includes a bracket 601 mounted on the storage area 2. A cylinder 603 is vertically mounted on the bracket 601, a movable seat 605 is mounted on the cylinder 603, and an air knife 602 is mounted on the movable seat 605. The cylinder 603 can control the movable seat 605 to rise and fall, adjusting the height of the air knife 602. A connecting air pipe 604 is mounted on the air knife 602. The connecting air pipe 604 is connected to an external air source. The cylinder 603 controls the movable seat 605 to rise and fall, causing the air outlet of the air knife 602 to move to the side of the battery cell. By blowing air through the air knife 602, the battery cell and the separator paper can be separated.

[0034] like Figure 6 As shown, the alignment mechanism 5 includes an alignment frame 501 mounted on the conveyor line 4. A track is mounted on the alignment frame 501, and symmetrical moving blocks 502 are mounted on the track. The moving blocks 502 can move on the track. A limit plate 504 is mounted on each moving block 502. The limit plates 504 are located on both sides of the conveyor line 4 and are arranged parallel to the conveyor line 4. Limiting wheels 505 are mounted on the limit plates 504. The straightening frame 501 has a drive wheel 510 and a driven wheel 509 mounted on both ends. Both the drive wheel 510 and the driven wheel 509 are connected to the straightening frame 501 via bearings and can rotate. The two ends of a transmission belt 506 are fitted onto the drive wheel 510 and the driven wheel 509. A drive device 503 is installed at the bottom of the straightening frame 501 to drive the drive wheel 510 to rotate. When the drive wheel 510 rotates, it drives the transmission belt 506 to rotate. It should be noted that the drive device 503 can be a servo motor, which controls the rotation angle for easy adjustment. Alternatively, a rotary cylinder or other rotating device can be used. Two limit plates 504 are fixedly connected to both sides of the transmission belt 506. As shown in the figure, the left limit plate 504 and the right limit plate 504 are connected to the upper and lower sides of the transmission belt 506, respectively.

[0035] When the solar cells are conveyed on conveyor line 4, the servo motor activates when a cell moves between two limit plates 504, driving the drive wheel 510 to rotate clockwise, which in turn drives the transmission belt 506 to rotate clockwise as well. This causes the two limit plates 504 to move at the same speed toward both sides of the solar cell. The distance the limit plates 504 move is set according to the size of the solar cell. When the position of the solar cell is abnormal, such as when it is tilted, the limit wheels 505 will contact both sides of the solar cell, changing its angle. Since the limit wheels 505 are linearly arranged, they can straighten the cell, thus completing the correction action. After correction, the servo motor reverses, causing the limit plates 504 to move back to their initial positions, and the solar cell moves with conveyor line 4 to the designated position.

[0036] The limiting plate 504 is connected to the transmission belt 506 via a clamping plate 507. The top of the clamping plate 507 is fixedly connected to the limiting plate 504, and the bottom clamps the transmission belt 506. The clamping plate 507 is fixed with two plate screws, allowing for quick disassembly and installation.

[0037] In this embodiment, the limiting wheel 505 is mounted on the limiting plate 504 via bearings, allowing the limiting wheel 505 to rotate. When the limiting wheel 505 contacts and corrects the battery cell, it will rotate to a certain extent. When the limiting wheel 505 cannot rotate, it will cause dry friction on the battery cell, resulting in wear on both sides of the battery cell. Therefore, the rotatable limiting wheel 505 can prevent damage to the battery cell.

[0038] In this embodiment, at least two limiting wheels 505 are provided, which can be two, three, four, or more, respectively installed at intervals at the head, middle, and tail of the limiting plate 504. This allows for contact with the head, middle, and tail of the battery cell, increasing the contact area for correction and improving the quality of correction. Figure 6 As shown, there are two limit wheels 505 here, which make contact with the head and tail of the battery cell, which can improve the correction quality and save costs.

[0039] Limiting blocks 508 are installed at both ends of the straightening frame 501 on the outer side of the driving wheel 510 and the outer side of the driven wheel 509 to limit the travel of the moving block 502 and prevent the moving block 502 from sliding off the track.

[0040] like Figure 1 As shown, a camera 7 is installed on the conveyor mechanism 1. The camera 7 takes pictures of the conveyor line 4. When the camera 7 captures a picture of release paper on the conveyor line 4, it reports an abnormality and notifies the operator to handle it. By adding another camera 7, it is possible to further prevent conveying errors from occurring.

[0041] like Figure 7 As shown, the recycling area 3 is surrounded by baffles 301, with two baffles 301 on each side. Each baffle 301 has a guide plate 302 extending outward from its top. The installation position of the baffles 301 is set according to the shape of the release paper, which can contain the release paper within the recycling area 3, while the inclined guide plate 302 facilitates the insertion and removal of the release paper.

[0042] It should be noted that conveyor line 4 consists of multiple conveyor lines. When one of the conveyor lines is damaged, only the damaged section needs to be repaired, making it easier for maintenance personnel to carry out repairs without having to disassemble the entire line. Sensors are also installed on each conveyor line section to detect the presence of battery cells and determine the location of battery cells in that section.

[0043] It should be further noted that multiple storage areas 2 can be set up, and storage areas 2 are placed on a conveyor belt and can be moved. When the initial battery cells in two of the storage areas 2 are used up, the conveyor belt will move the used storage area 2 to the outside, and a new storage area 2 will be moved to the working position. At this time, the operator can add initial battery cells to the storage area 2 without stopping the machine, without having to stop the machine to replace them.

[0044] In actual use, the initial battery cell is placed in storage area 2. Cylinder 603 drives air knife 602 to move to the initial battery cell, and air knife 602 blows air to separate the battery cell from the separator paper. Horizontal movement module 104 drives a set of vertical movement modules 105 to move above storage area 2. The vertical movement module 105 controls the conveying assembly 101 to descend, and the separator paper is picked up by suction cup 1012. The color sensor 102 makes a second judgment, and then the conveying assembly 101 is moved into storage area 2 through the cooperation of horizontal movement module 104 and vertical movement module 105. The suction cup 1012 is de-aired, and the separator paper is placed in storage area 2. Simultaneously, another vertical moving module 105 moves horizontally and controls the transport component 101 to descend. The suction cup 1012 picks up the battery cell, which is then re-identified by the color sensor 102. Afterwards, the horizontal moving module 104 and the vertical moving module 105 work together to move the transport component 101 onto the conveyor line 4. The suction cup 1012 is de-aired, and the battery cell is placed on the conveyor line 4. When the battery cell reaches the alignment mechanism 5, the drive device 503 drives the limit plate 504 to move and align the battery cell. The aligned battery cell is then moved by the conveyor line 4 to the subsequent workstation. When the isolation paper in the recycling area 3 is full, the operator removes the isolation paper for centralized processing.
