Description

Technical Field

[0001] This application relates to the technical field of battery cell edge passivation processing production line, and in particular to a material box cleaning device for a battery cell edge passivation processing production line. Background Technology

[0002] After solar cells are cut, the edges contain numerous dangling bonds and defects, which can become recombination centers for charge carriers (electrons and holes), leading to current loss. To improve photoelectric conversion efficiency, the edges of the solar cells need to be passivated. Specifically, this is achieved through alumina deposition, which saturates the dangling bonds at the edges, reducing the probability of charge carrier recombination and thus improving photoelectric conversion efficiency.

[0003] In the cell edge passivation production line, aluminum dioxide deposits will be generated on the passivated aluminum boat. At the same time, when the cells are loaded, fragments of the cells are left on the pads of the material box inside the aluminum boat, which can easily lead to unevenness of the cells when the material box is filled in later.

[0004] Reference Figure 1 , Figure 1 This is a schematic diagram of the material box structure.

[0005] The battery box is an essential transit box in the process of transporting solar cells. Each battery box has its own unique barcode. When solar cells with debris are assembled with the battery box, the debris and impurities will adhere to the surface of the battery box. The battery box with impurities is used repeatedly with the aluminum boat. Since the slots on the aluminum boat and the battery box are matched, the impurities on the surface of the battery box will accumulate more and more as it is used repeatedly. The battery box with more impurities will affect the fit with the aluminum boat and the positional accuracy of the solar cells placed in the battery box, which is not conducive to the transportation of solar cells. In addition, the impurities on the surface of the battery box can easily obscure the barcode information on the surface of the battery box, which will hinder the transportation of the battery box. Therefore, it is necessary to clean the surface of the battery box after the solar cells are removed from the battery box. Summary of the Invention

[0006] To improve the conveying efficiency of solar cells, this application provides a cleaning device for a material box in a solar cell edge passivation processing production line.

[0007] This application provides a material box cleaning device for a battery cell edge passivation processing production line, which adopts the following technical solution: A cleaning device for a battery cell edge passivation processing production line includes a cleaning box, which is rectangular in shape. Both ends of the cleaning box are slidably fitted with connecting plates. A first brush bristle is connected to the connecting plate and is located inside the cleaning box. An adjustment component for adjusting the position of the connecting plate is provided on the cleaning box. A cleaning component for cleaning the side wall of the cleaning box is provided on the side wall of the cleaning box. A collection component for collecting impurities is provided at the bottom of the cleaning box.

[0008] By adopting the above technical solution, the position of the connecting plate is pre-adjusted using the adjusting component to adjust the position of the first brush bristles. After the battery cells are unloaded from the material box, the robotic arm grabs the material box and places it into the cleaning box, which then moves up and down repeatedly. During this process, the first brush bristles clean impurities at both ends of the length direction of the material box, while the cleaning component cleans impurities in the width direction. After being cleaned, the impurities fall into the collection component, thus achieving the cleaning of the surface of the material box. By setting the first brush bristles and the cleaning component, impurities on the side wall of the material box are cleaned, ensuring that the material box remains clean when put into use. This ensures the placement position of the battery cells inside the material box, the insertion and mating accuracy of the material box in the aluminum boat, and the accurate detection of the barcode on the material box by the internal detection components of the machine. This ensures the stable and smooth transport of the battery cells inside the material box, improving the transport efficiency of the battery cells.

[0009] Optionally, a support frame is connected to the cleaning box, the connecting plate is L-shaped, a T-shaped block is connected to the connecting plate, and the connecting plate slides with the top of the support frame through the T-shaped block.

[0010] By adopting the above technical solution, the connection plate can be moved stably through the cooperation of the T-block and the support frame.

[0011] Optionally, the adjustment assembly includes a connecting frame, a limiting block, a connecting rod, a rotating frame, and a locking nut. The connecting frame is U-shaped and connected between the two connecting plates. The connecting frame has an adjustment hole. The limiting block is connected to the adjustment hole. The connecting rod is horizontally connected to the side wall of the cleaning box and passes through the adjustment hole. The connecting rod has a limiting groove. The limiting block slides into the limiting groove. The rotating frame is rotatably connected to the connecting frame and threadedly engaged with the connecting rod. The locking nut is threadedly engaged with the connecting rod and abuts against the rotating frame.

[0012] By adopting the above technical solution, when adjusting the position of the first brush bristles, the rotating frame is rotated. Through the threaded engagement of the rotating frame and the connecting rod and the sliding engagement of the limiting block and the limiting groove, the connecting frame is moved, which in turn moves the connecting plate to adjust the position of the first brush bristles. Finally, the anti-loosening nut is rotated to make the anti-loosening nut press against the rotating frame, thus realizing the adjustment of the position of the first brush bristles.

[0013] Optionally, the cleaning component is a nozzle, and several deformable air supply pipes are connected to the side wall of the cleaning box in the width direction. The cleaning component is connected to the end of the air supply pipe and faces the inside of the cleaning box. The air supply pipe is connected to an external air source, and the cleaning box is provided with a positioning component that limits the air jet angle of the cleaning component.

[0014] By adopting the above technical solution, when cleaning the side wall of the material box, the air supply pipe is rotated so that the nozzle faces the inside of the cleaning box, and the positioning component is used to limit the air jet direction of the nozzle. The external air source is sprayed onto the side wall of the material box through the air supply pipe and the nozzle, ensuring that the impurities on the side wall of the material box are blown off, thus achieving the cleaning effect of impurities on the side wall of the material box.

[0015] Optionally, the positioning assembly includes a fixed frame, a rotating hoop, a flipping rod, and a limiting flange. The fixed frame is connected to the top of the cleaning box. One end of the rotating hoop is rotatably connected to the fixed frame, and a limiting area is formed between the rotating hoop and the fixed frame. The limiting flange is connected to the other end of the rotating hoop. The flipping rod is L-shaped, with one end rotatably connected to the fixed frame and the other end connected to a connecting flange. When the limiting is applied, the connecting flange abuts against the limiting flange.

[0016] By adopting the above technical solution, the nozzle will generate a reaction force when it sprays air, and the nozzle is prone to deviating from its original position after long-term use. When restricting the nozzle, the air supply pipe is bent and inserted between the rotating clamp and the fixed frame. The flipping rod is rotated so that the connecting flange abuts against the restricting flange. Force is applied to the flipping rod, which deforms. The connecting flange passes through the restricting flange and abuts against another part of the restricting flange, thus achieving the positioning of the nozzle's air spray direction.

[0017] Optionally, a connecting block is connected to the connecting plate, the first brush bristles are connected to the connecting block, and extension frames are connected to the opposite side walls of the connecting block. Second brush bristles for cleaning the side walls in the width direction of the material box are connected to the extension frames.

[0018] By employing the above technical solution, the cleaning component uses area-based airflow, which is not as effective as direct contact cleaning. By adding a second brush to clean the sidewalls of the material box along its width, working in conjunction with the cleaning component, the cleaning effect on the sidewalls of the material box is further improved.

[0019] Optionally, the collecting component is a collecting box, which is placed directly below the cleaning box. A rotating plate is rotatably connected to the collecting component, and a magnetic block is embedded in the rotating plate. The cleaning box is made of magnetic material. During collection, the rotating plate is attracted to the surface of the cleaning box by the magnetic block, and the rotating plate is in a vertical state.

[0020] By adopting the above technical solution, when staff transport collection items containing impurities, the rotating plate is used to cover the collection items to prevent impurities from flying. During collection, the rotating plate is attached to the surface of the cleaning box by magnetic blocks, ensuring that the collection items will not move under force.

[0021] Optionally, the bottom of the cleaning box is shaped like a frustum, with the smaller end being the bottom of the cleaning box.

[0022] By adopting the above technical solution, the bottom of the cleaning box is designed in a frustum shape to ensure that impurities fall into the middle part of the cleaning component, reducing the possibility of impurities drifting to the outside of the collection component.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. The position of the connecting plate is pre-adjusted using the adjustment component to adjust the position of the first brush bristles. After the battery cells are removed from the material box, the robotic arm picks up the material box and places it into the cleaning box, which then moves up and down repeatedly. During this process, the first brush bristles clean impurities at both ends of the length direction of the material box, while the cleaning component cleans impurities in the width direction. The impurities fall into the collection component after being cleaned, thus cleaning the surface of the material box. By setting the first brush bristles and the cleaning component, impurities on the side wall of the material box are cleaned, ensuring that the material box remains clean when it is put into use. This ensures the placement position of the battery cells inside the material box, the insertion and mating accuracy of the material box in the aluminum boat, and the accurate detection of the barcode on the material box by the internal detection components of the machine. This ensures the stable and smooth transport of the battery cells in the material box, improving the transport efficiency of the battery cells. 2. When adjusting the position of the first brush bristles, rotate the rotating frame. Through the threaded engagement of the rotating frame and the connecting rod, and the sliding engagement of the limiting block and the limiting groove, the connecting frame moves, which in turn moves the connecting plate to adjust the position of the first brush bristles. Finally, rotate the anti-loosening nut to make the anti-loosening nut press against the rotating frame, thus realizing the adjustment of the position of the first brush bristles.

Detailed Implementation

[0032] The following is in conjunction with the appendix Figures 2-7 This application will be described in further detail.

[0033] This application discloses a material box cleaning device for a battery cell edge passivation processing production line. (Refer to...) Figure 2 The cleaning device for the battery cell edge passivation processing production line includes a cleaning box 1, which is rectangular in shape, and a support frame 11 is fixedly connected to both ends of the cleaning box 1 along its length.

[0034] Reference Figure 1 and Figure 2 The cleaning box 1 has connecting plates 2 at both ends along its length. The connecting plates 2 are L-shaped, and T-shaped blocks are fixedly connected to them. The connecting plates 2 slide against the top wall of the support frame 11 via the T-shaped blocks, and the two connecting plates 2 are positioned opposite each other. A connecting block is fixedly connected to the end of the connecting plate 2 inside the cleaning box 1, and a first brush bristle 21 is fixedly connected to the connecting block. Extension frames are fixedly connected to the opposite side walls of the connecting blocks. The extension frames are L-shaped, and second brush bristles 22 are fixedly connected to their ends.

[0035] Two first bristles 21 are used to clean the two end walls of the material box along its length, and two second bristles 22 are used to clean the two side walls along its width.

[0036] Refer to,3. Figure 4 and Figure 5 The cleaning box is equipped with an adjustment assembly 3, which includes a connecting frame 31, a limiting block 32, a connecting rod 33, a rotating frame 34, and a locking nut 35. The connecting frame 31 is U-shaped and fixedly connected between two connecting plates 2, with an adjustment hole. The limiting block 32 is fixedly connected within the adjustment hole. The connecting rod 33 is horizontally fixedly connected to the side wall of the adjustment box, and a limiting groove 331 is formed on its surface along its length. The connecting rod 33 passes through the adjustment hole, and the limiting block 32 and the limiting groove 331 are in sliding engagement. The rotating frame 34 is rotatably connected to the connecting frame 31 and threadedly engaged with the connecting rod 33. The locking nut 35 is threadedly engaged with the connecting rod 33 and abuts against the rotating frame 34.

[0037] During adjustment, the rotating frame 34 is rotated, and the connecting frame 31 is moved by the sliding fit of the limiting block 32 and the limiting groove 331 and the threaded fit of the rotating frame 34 and the connecting rod 33, thereby moving the connecting plate 2 to adjust the position of the first brush bristle 21 and the second brush bristle 22, so as to match the cleaning position of the material box.

[0038] Reference Figure 1 and Figure 6 The cleaning box 1 has several cleaning components 4 on its side wall. Each cleaning component 4 is a nozzle, and several air jet pipes are installed on each cleaning component 4. In this embodiment, two air jet pipes are used as an example. The air jet pipes are multi-section pipes and are connected to an external air source. The cleaning components 4 face the inside of the cleaning box 1.

[0039] Reference Figure 6 and Figure 7 The cleaning box 1 is equipped with a positioning component 5, which includes a fixing frame 51, a rotating hoop 52, a flipping rod 53, and a limiting flange 54. The fixing frame 51 is fixedly connected to the cleaning box 1. One end of the rotating hoop 52 is hinged to the fixing frame 51, and the limiting flange 54 is fixedly connected to the other end of the rotating hoop 52, forming a limiting area between the rotating hoop 52 and the fixing frame 51. The jet pipe passes through the limiting area. The flipping rod 53 is L-shaped, with one end hinged to the side wall of the fixing frame 51 and the other end fixedly connected to a connecting flange 531. The connecting flange 531 abuts against the limiting flange 54 near the jet pipe.

[0040] When positioning the cleaning component 4, the jet pipe is bent, and then the rotating clamp 52 is flipped to bring the jet pipe into the restricted area. Finally, the flipping rod 53 is rotated. During this process, the connecting flange 531 abuts against the restricting flange 54, the flipping rod 53 deforms, and the connecting flange 531 passes through the restricting flange 54 and abuts against the portion of the restricting flange 54 near the jet pipe to restrict the rotation of the flipping rod 53, thus achieving the positioning effect of the cleaning component 4.

[0041] Reference Figure 3 The bottom of the cleaning box 1 is truncated into a frustum shape, with the smaller end being the bottom of the cleaning box 1. A collection component 6, which is the collection box, is placed directly below the cleaning box 1. A rotating plate 61 is rotatably connected to the collection component 6, and a magnetic block 62 is embedded in the rotating plate 61. The cleaning box 1 is made of a magnetic material, such as alloy structural steel. The rotating plate 61 is attached to the surface of the cleaning box 1 by the magnetic block 62 and is in a vertical position.

[0042] When cleaning the collection item 6, the staff covers the surface of the collection item 6 with the cleaning box 1, which reduces the possibility of dust from internal impurities and makes it easier to clean the impurities.

[0043] The implementation principle of the material box cleaning device for a battery cell edge passivation processing production line according to an embodiment of this application is as follows: During cleaning, a mechanical claw grabs a material box and places it into the cleaning box 1. The material box is moved up and down. During this process, the impurities on the four side walls of the material box are removed by the cooperation of the first brush 21 and the second brush 22. Then, the cleaning component 4 sprays air to clean the material box in a range, so that the first brush 21, the second brush 22 and the impurities on the side walls of the material box are blown into the cleaning box 1. The impurities fall into the collection component 6, thus achieving the effect of cleaning the material box.

[0044] The position of the connecting plate 2 is pre-adjusted using the adjusting component 3 to adjust the position of the first brush bristles 21. After the battery cells are removed from the material box, the material box is picked up by the robotic arm and placed into the cleaning box 1, which then moves up and down repeatedly. During this process, the first brush bristles 21 cleans impurities at both ends of the length direction of the material box, and the cleaning component 4 cleans impurities in the width direction. After being cleaned, the impurities fall into the collecting component 6, thus cleaning the surface of the material box. By setting the first brush bristles 21 and the cleaning component 4, impurities on the side wall of the material box are cleaned, ensuring that the material box remains clean when it is put into use. This ensures the placement position of the battery cells inside the material box, the insertion and fitting accuracy of the material box in the aluminum boat, and the accurate detection of the barcode on the material box by the internal detection components of the machine. This ensures the stable and smooth transport of the battery cells in the material box, improving the transport efficiency of the battery cells.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
