An adjustment component is installed at the bottom of the grabbing component, and a bearing component is arranged at the bottom of the grabbing component and below the adjustment component. The device solves the problem that when the monocrystalline cell wafer is taken out, the velvet surface after texturing causes the water between adjacent cells to fall more slowly, and the liquid does not drip completely, and the water accumulation affects the treatment effect and subsequent drying efficiency. The device is provided with a clamping groove and a protrusion, and the vertical plate and the monocrystalline cell wafer are vibrated when the insertion rod moves, so as to accelerate the flow of water and improve the texturing and cleaning efficiency. The electric clamp works in coordination with the driving cylinder, and the interlaced separation of the cell wafers is achieved through the adjustment rod and the hinge rod, which is convenient for subsequent drying.

Description

Technical Field

[0001] The present invention relates to the technical field of single crystal cell sheets, and more specifically, to a cleaning and texturing device for single crystal cell sheets. Background Art

[0002] Monocrystalline cells, also known as monocrystalline silicon cells, are cells made of monocrystalline silicon. They are widely used in the field of solar power generation due to their high conversion efficiency, good stability and long service life.

[0003] Texturing of single crystal cells is a key step in the production of solar cells. Its purpose is to increase the surface area of ​​the silicon wafer by forming a pyramid-structured texture, thereby improving light absorption and cell conversion efficiency.

[0004] At present, single crystal cells are arranged vertically and equidistantly in a cell basket. Therefore, after the cells are immersed in chemical reagents or deionized water, the chemical reagents or deionized water will flow between two single crystal cells to react. When the cells are taken out of the chemical reagents or deionized water, the solution will flow downward and drip. After the cells are subjected to the texturing operation, a velvet surface will be formed on the surface of the cells. Therefore, the falling speed of the water between two adjacent cells will be slowed down, and water will accumulate. When the subsequent drying operation is performed, the drying efficiency will be affected.

[0005] Moreover, when the battery cell is taken out of the deionized water, it is necessary to wait for the excess water attached to it to drip off completely to ensure that it will not be brought into the subsequent chemical treatment steps. If the battery cell with water droplets is directly immersed in the next chemical reagent, it will not only dilute the concentration of the reagent, thereby affecting its treatment effect, but may also cause instability in the chemical reaction.

[0014] By adopting the above technical solution, the electric slide rail slides on the first guide rail, and the gear is driven to rotate by the driving motor, so that the gear moves on the rack, thereby driving the electric slide rail to slide on the first guide rail. The bracket is affected by the driving force to drive the grabbing component to move, and at the same time, the electric slide rail drives the bracket to move up and down, thereby controlling the height of the grabbing component, so that the grabbing component can move horizontally and adjust the up and down height at the same time, which is convenient for the grabbing component to grab and transfer the single crystal battery cell.

[0015] The present invention is further configured as follows: the two vertical plates are arranged opposite to each other, the side walls of each vertical plate are installed with two second guide rails, the two second guide rails are arranged up and down, each of the second guide rails is slidably connected to two slides, the two slide side walls corresponding to the upper second guide rails are connected to the second rod body, the two slide side walls corresponding to the lower second guide rails are connected to the third rod body, the first rod body is connected between one of the second rod bodies and one of the third rod bodies, and the positioning mechanism is installed between the two third rod bodies and the two second rod bodies.

[0016] The present invention is further configured as follows: the positioning mechanism includes two first positioning plates, the two first positioning plates are respectively installed between the two second rod bodies, and a plurality of fixing blocks are equidistantly installed between the two first positioning plates, a plurality of L-shaped grooves are equidistantly installed on the tops of the two third rod bodies, and the L-shaped grooves on the tops of the two third rod bodies are equidistantly and staggeredly arranged.

[0017] The present invention is further configured as follows: a first through groove is formed at the bottom of each L-shaped groove, a second through groove is formed at one side of the L-shaped groove, and a groove is formed at the top of the L-shaped groove.

[0018] The present invention is further configured as follows: a protrusion is installed on the inner top wall of each of the clamping grooves, the protrusions are in multiple groups and are arranged at equal distances, and the bottom of the protrusion is arranged in an arc shape.

[0019] By adopting the above technical scheme, the top and bottom of the card slot are separated by a block, the insertion rod slides on the top of the moving block and at the same time slides at the bottom of the protrusion, the insertion rod switches different protrusions, and makes the vertical plate vibrate during the movement, and the vertical plate applies vibration force to the positioning mechanism and the single crystal battery cell, causing the single crystal battery cell to vibrate, thereby accelerating the flow of water between adjacent single crystal battery cells, avoiding the situation where the water flow speed is slow when the surface of the single crystal battery cell is velvet, affecting the velveting and cleaning efficiency, and by setting the shape of the L-shaped groove, when the L-shaped grooves installed on the two third rods are staggered and separated, the vertical part of the L-shaped groove applies a pushing force to the corresponding battery cell, avoiding the situation where the battery cell is separated from the L-shaped groove.

[0020] The present invention is further configured as follows: the adjustment assembly includes an adjustment rod arranged above the two vertical plates, both ends of the adjustment rod are connected to connecting rods, and two second hinged rods are symmetrically hinged at both ends of the connecting rod, and the ends of the two second hinged rods away from the corresponding connecting rods are respectively hinged to two slides above the side walls of one of the vertical plates.

[0023] By adopting the above technical scheme, the driving cylinder is used to drive the electric clamp to move downward, causing the electric clamp to move to the position of the adjustment rod and clamp the adjustment rod 44 through the electric clamp. When the piston rod of the driving cylinder is shortened, the adjustment rod is pulled upward, and the adjustment rod pulls the second hinged rod to swing, causing the corresponding slide to move toward the end of the second guide rail, causing the L-shaped grooves on the two third rod bodies to move away from each other, thereby achieving staggered separation of the battery cells, which is convenient for subsequent drying operations. Conversely, the piston rod of the driving cylinder is extended, the adjustment rod is pushed downward, and the adjustment rod pushes the second hinged rod to swing, causing the corresponding slide to move toward the middle of the second guide rail, causing the L-shaped grooves on the two third rod bodies to approach each other, thereby achieving equidistant placement of the battery cells. When the grabbing assembly leaves the carrying assembly, since the second hinged rod is tilted toward the middle of the second guide rail as a whole, the adjustment rod is affected by its own gravity to keep the second hinged rod in an extruded state, and the battery cells remain in an equidistant placement state, which is convenient for soaking, cleaning and cashmere making of the battery cells.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] (1) By setting a snap-in groove and a protrusion, the top and bottom of the snap-in groove are separated by a block, and the insertion rod slides on the top of the movable block and slides on the bottom of the protrusion at the same time. The insertion rod switches different protrusions and causes the vertical plate to vibrate during the movement. The vertical plate applies vibration force to the positioning mechanism and the single crystal cell, causing the single crystal cell to vibrate, thereby accelerating the flow of water between adjacent single crystal cell cells, avoiding the situation where the water flow speed is slow when the surface of the single crystal cell is velvet, affecting the velvet making and cleaning efficiency.

[0026] (2) By setting the L-shaped groove, when the battery cells are immersed, the solution flows through the gap between two adjacent battery cells, and the solution flows through the first through groove, the groove and the second through groove. After the battery cells are placed, there is a gap between the L-shaped groove and the fixing block, that is, the battery cells are provided with a clearance within the restricted mechanism, thereby ensuring that the part blocked by the L-shaped groove can also be immersed.

[0027] (3) When the electric clamp clamps the adjustment rod and the piston rod of the driving cylinder is shortened, the adjustment rod is pulled upward, and the adjustment rod pulls the second hinged rod to swing, causing the corresponding slide to move toward the end of the second guide rail, causing the L-shaped grooves on the two third rods to move away from each other, thereby achieving staggered separation of the battery cells and facilitating subsequent drying operations.

[0028] (4) By setting the shape of the L-shaped groove, when the L-shaped grooves installed on the two third rods are staggered and separated, the vertical part of the L-shaped groove exerts a pushing force on the corresponding battery cell to prevent the battery cell from being separated from the L-shaped groove.

[0045] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0046] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0047] See also Figure 1-Figure 9 , the present invention provides the following technical solutions:

[0048] Embodiment 1, a cleaning and texturing device for a single crystal cell, comprises a main body component 1, the main body component 1 is used to place various chemical agents and set a cleaning and texturing environment, so as to facilitate subsequent cleaning and texturing operations of the single crystal cell. The specific structure of the main body component 1 is as follows:

[0049] The main component 1 includes a frame 11, a baffle 14 arranged inside the frame 11, and two groups of conveyor belts 12 arranged on one side of the baffle 14. A plurality of water troughs 13 are arranged equidistantly between the two groups of conveyor belts 12. The baffle 14 is used to divide the internal space of the frame 11 into two parts, one of which is used to place the conveyor belt 12 and the water trough 13. One group of conveyor belts 12 is used to convey the single crystal cell pieces, and the other group of conveyor belts 12 is used to discharge the single crystal cell pieces after cleaning and texturing. The water trough 13 is used to place various chemical reagents or deionized water, that is, before texturing, the single crystal cell pieces need to be pre-cleaned, and deionized water is added to the first water trough 13 to remove most of the surface pollutants to ensure the cleanliness of the surface. During the texturing process, the subsequent water troughs 13 are respectively set with NaOH solution, H2O2 / NaOH mixed solution, HCl solution, HF solution and deionized water. The deionized water is set in the water trough 13 between two solutions as needed. The low concentration NaOH solution is used to corrode the surface of the silicon wafer to form a pyramid-shaped velvet structure. The concentration, temperature and reaction time of NaOH will affect the quality and morphology of the velvet surface. H2O2 is used as a strong oxidant to oxidize-dissolve-reoxidize-redissolve the organic pollutants on the surface of the silicon wafer together with NaOH in a cycle to completely remove the pollutants. HCl solution is used to neutralize the residual alkali solution (such as NaOH) on the silicon wafer to ensure that the pH value on the surface of the silicon wafer is neutral or close to neutral. HF solution is used to remove the oxide layer on the surface of the silicon wafer and may be mixed with HCl to remove metal ions. The strong corrosiveness of HF can ensure the cleanliness and smoothness of the surface of the silicon wafer. After each chemical treatment, it is necessary to rinse with deionized water to remove the residues and impurities on the surface of the silicon wafer. A top plate 15 is installed inside the frame 11. The top plate 15 is arranged in a trapezoidal shape and is located above the water tank 13. The single crystal cell reacts with the chemical reagent during the cleaning and velveting process to generate steam. The top plate 15 is used to intercept the steam and effectively collect the generated steam.

[0050] A conveying assembly 2 is installed inside the main assembly 1, and a grabbing assembly 3 is connected to one side of the conveying assembly 2. The conveying assembly 2 is used to control the position of the grabbing assembly 3 inside the main assembly 1, so that the grabbing assembly 3 can grab the monocrystalline cell sheets and place them in different water tanks 13 in sequence. The specific structure of the conveying assembly 2 is as follows:

[0051] The conveying assembly 2 is arranged on the side of the baffle 14 away from the water tank 13, and one side of the conveying assembly 2 passes through the top of the baffle 14 and is connected to the grabbing assembly 3. The conveying assembly 2 includes two first guide rails 21 installed on the side of the baffle 14 away from the water tank 13 and an electric slide rail 22 slidably connected to the first guide rail 21. The electric slide rail 22 is vertically arranged, and the side wall of the electric slide rail 22 is slidably connected with a bracket 25. One end of the bracket 25 passes through the baffle 14 and is connected to the grabbing assembly 3. A driving motor 23 is installed on one side of the electric slide rail 22, and a gear 26 is installed at the output end of the driving motor 23. A rack 24 is installed at the bottom of the first guide rail 21, and the rack 24 is meshed with the gear 26. The electric slide rail 22 slides on the first guide rail 21, and the gear 26 is driven to rotate by the driving motor 23, so that the gear 26 moves on the rack 24, thereby driving the electric slide rail 22 to slide on the first guide rail 21. The bracket 25 is affected by the driving force and drives the grasping component 3 to move. At the same time, the electric slide rail 22 drives the bracket 25 to move up and down, thereby controlling the height of the grasping component 3, so that the grasping component 3 can move horizontally and adjust the up and down height at the same time, which is convenient for the grasping component 3 to grasp and transfer the single crystal battery sheet.

[0052] The specific structure of the grabbing component 3 is as follows:

[0053] The grabbing assembly 3 is located above the water tank 13. The grabbing assembly 3 includes a connecting frame 31 connected to the conveying assembly 2 and two telescopic cylinders 32 symmetrically installed inside the connecting frame 31. The piston rods of the two telescopic cylinders 32 are respectively connected to the slides 33. When the bracket 25 moves, the connecting frame 31 of the grabbing assembly 3 is synchronously driven to move synchronously, thereby driving the grabbing assembly 3 to move as a whole. The bottom of the connecting frame 31 is symmetrically connected to two limit rods 34. The two limit rods 34 are arranged corresponding to the two slides 33. The outer side wall of each limit rod 34 is slidably connected to two sliders 35. The side walls of each slide 33 are symmetrically hinged to two first hinge rods 36. The two first hinges The end of the connecting rod 36 away from the corresponding slide plate 33 is hinged to the side walls of the two sliders 35 respectively, and the bottom of each slider 35 is connected to an L-shaped plate 37, and the side wall of the L-shaped plate 37 is horizontally connected to an insertion rod 38. The telescopic cylinder 32 is used to drive the slide plate 33 to move up and down. When moving, the slide plate 33 pushes or pulls one end of the first hinged rod 36 to move, and the other end of the first hinged rod 36 pushes or pulls the corresponding slide block 35 to slide on the limit rod 34, that is, when the slide plate 33 moves down, the two slide blocks 35 separate from each other, and when the slide plate 33 moves up, the two slide blocks 35 approach each other, and the slide block 35 drives the corresponding L-shaped plate 37 and the insertion rod 38 to move synchronously during the movement.

[0054] A carrying component 5 is provided at the bottom of the grabbing component 3. The carrying component 5 is used to arrange and place the monocrystalline cell sheets, that is, the monocrystalline cell sheets are placed vertically, and gaps are set between multiple monocrystalline cell sheets. When the L-shaped plate 37 and the insertion rod 38 in the grabbing component 3 move, the carrying component 5 can be grabbed. The carrying component 5 passes through multiple water tanks 13 in turn, and the monocrystalline cell sheets are immersed in the chemical reagents or deionized water in the water tanks 13 to react, thereby completing the cleaning and texturing operation of the placed monocrystalline cell sheets.

[0055] In the second embodiment, since the monocrystalline cell pieces are arranged vertically and equidistantly in the supporting assembly 5, after the cell pieces are immersed in chemical reagents or deionized water, the chemical reagents or deionized water will flow between two monocrystalline cell pieces to react. When the cell pieces are taken out from the water tank 13, the solution will flow downward and drip into the water tank 13. After the cell pieces are subjected to the texturing operation, a velvet surface will be formed on the surface of the cell pieces. Therefore, the falling speed of the water between two adjacent cell pieces will become slower, and water will accumulate. Moreover, when the cell pieces are taken out from the deionized water tank 13, it is necessary to wait for the water to drip before being immersed in the next chemical reagent. If it is immersed directly, the concentration of the next chemical reagent will be affected.

[0056] To this end, the carrier assembly 5 includes two vertical plates 51, and multiple groups of positioning mechanisms 57 are equidistantly arranged between the two vertical plates 51. The side wall of each vertical plate 51 is symmetrically provided with two clamping grooves 59, and the clamping groove 59 corresponds to one of the plug rods 38. The clamping groove 59 is arranged in a U shape, and the top and bottom of the clamping groove 59 are separated by a block. The battery cell is vertically placed in the multiple groups of positioning mechanisms 57, and then the grasping assembly 3 grasps the carrier assembly 5, and the grasping method is as follows:

[0057] By moving the L-shaped plate 37 and the insertion rod 38, the corresponding two L-shaped plates 37 are moved to the two sides of one of the vertical plates 51, and then the insertion rod 38 on the L-shaped plate 37 moves to the opening of the card slot 59 on the side wall of the corresponding vertical plate 51. Then, the two corresponding L-shaped plates 37 approach each other, and the insertion rod 38 on the L-shaped plate 37 slides into the inside of the card slot 59. Then, the grasping component 3 lifts the bearing component 5. During this process, the insertion rod 38 slides upward on the inner wall of the corresponding card slot 59. Then, the two L-shaped plates 37 drive the corresponding insertion rods 38 to separate from each other, causing the insertion rod 38 to slide above the stopper inside the corresponding card slot 59.

[0058] In this embodiment, a protrusion 58 is installed on the inner top wall of each snap-in groove 59. The protrusions 58 are in multiple groups and are arranged equidistantly. The bottom of the protrusion 58 is arranged in an arc shape. The insertion rod 38 slides on the top of the moving block and slides on the bottom of the protrusion 58 at the same time. The insertion rod 38 switches different protrusions 58 and causes the vertical plate 51 to vibrate during the movement. The vertical plate 51 applies vibration force to the positioning mechanism 57 and the single crystal cell, causing the single crystal cell to vibrate, thereby accelerating the flow of water between adjacent single crystal cell pieces, and avoiding the situation where the water flow speed is slow when the surface of the single crystal cell is velvet, affecting the velvet making and cleaning efficiency.

[0059] In the third embodiment, the single crystal cell needs to be dried after cleaning and texturing. The existing method is to dry it by blowing hot air. Although the micro-vibration method is used to speed up the flow of water between the single crystal cell pieces, it can only reduce the amount of water between the cell pieces. Water droplets may still accumulate on the side walls of a single cell. Direct drying with air will cause uneven drying. After drying the place without water, it is necessary to wait for the place with water to dry.

[0060] Therefore, two second guide rails 55 are installed on the side wall of each vertical plate 51, and the two second guide rails 55 are arranged up and down. Two slides 56 are slidably connected to each second guide rail 55, and the side walls of the two slides 56 corresponding to the upper second guide rail 55 are connected to the second rod body 53, and the side walls of the two slides 56 corresponding to the lower second guide rail 55 are connected to the third rod body 54, and the first rod body 52 is connected between one of the second rod bodies 53 and one of the third rod bodies 54. The two vertical plates 51, the two second rod bodies 53, the two third rod bodies 54 and the four first rod bodies 52 cooperate to form a bearing frame structure, and the positioning mechanism 57 is installed between the two third rod bodies 54 and the two second rod bodies 53.

[0061] The positioning mechanism 57 includes two first positioning plates 571, and the two first positioning plates 571 are respectively installed between the two second rod bodies 53, and a plurality of fixing blocks 572 are equidistantly installed between the two first positioning plates 571. A plurality of L-shaped grooves 573 are equidistantly installed on the tops of the two third rod bodies 54, and the L-shaped grooves 573 on the tops of the two third rod bodies 54 are equidistantly staggered. When the single crystal cell is placed, the single crystal cell first passes through the side walls of the fixing blocks 572 opposite to each other between the two first positioning plates 571, and continues to be inserted downward into the corresponding L-shaped grooves 573, and a plurality of cell sheets are placed in sequence.

[0062] A first through groove 575 is provided at the bottom of each L-shaped groove 573, a second through groove 576 is provided on one side of the L-shaped groove 573, and a groove 574 is provided at the top of the L-shaped groove 573. When the battery cells are immersed, the solution flows through the gap between two adjacent battery cells, and the solution flows through the first through groove 575, the groove 574 and the second through groove 576. After the battery cells are placed, there is a gap between the L-shaped groove 573 and the fixing block 572, that is, the battery cells are provided with a clearance in the restricted mechanism, thereby ensuring that the part blocked by the L-shaped groove 573 can also be immersed.

[0063] When the battery cells have passed through all the water tanks 13 and completed cleaning and texturing, they are moved to the unloading conveyor belt 12, where an external drying mechanism is installed. The external drying mechanism can be a heater, which blows hot air to the surface of the battery cells to achieve the purpose of drying the battery cells.

[0064] At the same time, an adjustment component 4 is installed at the bottom of the grabbing component 3. The adjustment component 4 is used to stagger and separate the battery cells placed in parallel, which can not only pull apart the residual water connecting the adjacent battery cells, but also expose most of the side walls of each battery cell, thereby achieving the purpose of rapid drying.

[0065] The specific structure of adjustment component 4 is as follows:

[0066] The adjustment assembly 4 includes an adjustment rod 44 arranged above the two vertical plates 51, and both ends of the adjustment rod 44 are connected to a connecting rod 45. Two second hinged rods 46 are symmetrically hinged at both ends of the connecting rod 45. One end of the two second hinged rods 46 away from the corresponding connecting rod 45 is respectively hinged to two slides 56 above the side wall of one side of the vertical plate 51. By moving the adjustment rod 44 and the connecting rod 45 up and down, the top end of the second hinged rod 46 moves up and down, and the other end of the second hinged rod 46 is affected by the pushing or pulling force to move, and the second hinged rod 46 is The bottom end of 46 is hinged to the side wall of the slide 56 which can only be displaced horizontally. Therefore, when the second hinged rod 46 is pushed or pulled, the corresponding slide 56 slides on the corresponding second guide rail 55, thereby causing the corresponding second rod body 53, the third rod body 54 and the first rod body 52 to move synchronously, causing the L-shaped groove 573 connected to the corresponding third rod body 54 to be displaced synchronously, and the L-shaped grooves 573 installed on the two third rod bodies 54 are staggered and separated, and the vertical part of the L-shaped groove 573 applies a pushing force to the corresponding battery cell to prevent the battery cell from being separated from the L-shaped groove 573.

[0067] Since the existing mechanism only sets a limiting structure with a clearance to limit the battery cell, if the limiting structure moves, the battery cell is not clamped and pulled, so the battery cell cannot be pulled and displaced. The present invention adopts an L-shaped groove 573 to change the clamping method of the battery cell, which facilitates the battery cell to move synchronously with the L-shaped groove 573, thereby achieving the purpose of separating adjacent battery cells.

[0068] In this embodiment, specifically: a vertical rod 47 is vertically installed on the top of each of the two vertical plates 51, and the top of the vertical rod 47 passes through the opposite side of one of the connecting rods 45. When the adjustment rod 44 moves up and down, the position of the adjustment rod 44 and the connecting rod 45 is limited by the vertical rod 47 to avoid the adjustment rod 44 and the connecting rod 45 offset to cause the swing angles of the two second hinged rods 46 to be inconsistent.

[0069] In this embodiment, the adjustment component 4 also includes a cross bar 41, and the two ends of the cross bar 41 are respectively connected to the middle of the outer wall of the two limit rods 34. A driving cylinder 42 is installed on the top of the cross bar 41, and two electric clamps 43 are installed on the bottom of the driving cylinder 42. The two electric clamps 43 extend downward. The driving cylinder 42 is used to drive the electric clamps 43 to move downward, so that the electric clamps 43 move to the position of the adjustment rod 44, and clamp the adjustment rod 44 through the electric clamps 43. When the piston rod of the driving cylinder 42 is shortened, the adjustment rod 44 is pulled upward, and the adjustment rod 44 pulls the second hinged rod 46 to swing, causing the corresponding slide 56 to move toward the end of the second guide rail 55, causing the two third rod bodies The L-shaped grooves 573 on 54 are away from each other, so that the battery cells are staggered and separated, which is convenient for subsequent drying operations. On the contrary, the piston rod of the driving cylinder 42 is extended, and the adjusting rod 44 is pushed downward, and the adjusting rod 44 pushes the second hinged rod 46 to swing, causing the corresponding slide 56 to move toward the middle of the second guide rail 55, so that the L-shaped grooves 573 on the two third rod bodies 54 are close to each other, so that the battery cells are placed equidistantly. When the grasping component 3 leaves the supporting component 5, since the second hinged rod 46 is tilted toward the middle of the second guide rail 55 as a whole, the adjusting rod 44 is affected by its own gravity to keep the second hinged rod 46 in an extruded state, and the battery cells are kept in an equidistant placement state, which is convenient for the soaking, cleaning and texturing of the battery cells.

[0070] Obviously, the above-described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
