Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic cells, and more specifically, to a paper separator removal device and photovoltaic cell processing equipment. Background Art

[0002] In some processes of the photovoltaic cell production process, the incoming cells are stacked and stored in the thickness direction, and adjacent cells are separated by separators to avoid mutual wear between adjacent cells.

[0003] However, the separator paper and the battery cells may stick to each other, causing the battery cells to stick to the separator paper when the material is removed, affecting the normal progress of subsequent processes. Utility Model Content

[0004] The present application provides a paper separator removal device and photovoltaic cell processing equipment to solve the problem that the cell adheres to the paper separator and affects the subsequent process.

[0005] In a first aspect, the present application provides a paper separator removal device, which includes a material tray and a static electricity removal component. The material tray is used to carry a plurality of stacked battery cells, and a paper separator is provided between two adjacent battery cells. The static electricity removal component is located in a discharge path of the battery cells, and the static electricity removal component is configured to remove static electricity from the battery cells and / or paper separators discharged through the discharge path.

[0006] In the paper separator removal device of the present application, the static electricity removal component is arranged on the discharge path of the battery cell. During the discharge process, if the lower surface of the battery cell is adhered with the separator due to static electricity, the static electricity on the battery cell and the separator can be removed by the static electricity removal component when passing through the static electricity removal component, which is conducive to the adhered separator falling due to its own weight, thereby separating the separator and the battery cell from each other, which is conducive to ensuring the reliability of the separator removal. Similarly, if the lower surface of the separator is adhered with the battery cell due to static electricity and / or vacuum adsorption when removing the separator, after the static electricity is removed, the battery cell can also fall due to its own weight, thereby separating the battery cell and the separator.

[0007] In a possible embodiment, the static electricity removal component includes a conductive structure, which is located on the discharge path of the battery cell and is used to contact the battery cell and / or separator paper passing by to remove static electricity on the battery cell and / or separator paper.

[0008] In this embodiment, the conductive structure can conduct the charges on the battery cell and / or the separator paper by contact, thereby removing the electrostatic attraction between the separator paper and the battery cell.

[0009] In a possible implementation, the conductive structure includes bristles, which are flexible bristles, and the free ends of the bristles extend into the discharge path of the battery cell, so as to contact the battery cell and deform to allow the battery cell to pass through.

[0010] In this embodiment, when the battery cell is discharged along the discharge path, it will touch the bristles upwards and transfer the charge on it to the bristles, eliminating the static electricity between the battery cell and the separator paper, and eliminating the static adsorption between the separator paper and the battery cell. At the same time, due to the flexibility of the bristles, it can deform and give way when the battery cell continues to discharge upwards, and return to its original state after the battery cell passes, ensuring the removal of static electricity when the next battery cell is discharged.

[0011] In a possible implementation, the static electricity removal component further includes a brush handle connected to the material tray, with one end of the bristles fixed to the brush handle and the other end extending into the material tray.

[0012] In this embodiment, the brush handle is provided to facilitate the fixation of the bristles and the installation of the static electricity removal component.

[0013] In a possible implementation, the brush handle is provided with a blowing channel, and the blowing channel is used to blow air toward the battery sheet and / or the separator paper passing by. The air outlet of the blowing channel is provided on a side surface of the brush handle where the bristles are provided.

[0014] In this embodiment, the brush handle is provided with a blowing channel to facilitate the separation of the separator paper from the battery sheet by blowing while removing static electricity.

[0015] In a possible implementation, there are multiple air outlets, and the multiple air outlets are arranged in a direction parallel to the panel surface of the battery cell.

[0016] In this embodiment, the parallelly arranged air blowing ports can blow horizontal wind, which is beneficial for the separator paper on the battery cell currently being discharged to separate from the battery cell.

[0017] In a possible implementation, the battery cell is polygonal. There are multiple static electricity removal components, and the multiple static electricity removal components are respectively distributed at multiple corners of the battery cell. The brush handle is arranged at intervals outside the discharge path of the battery cell, and the bristles at least partially extend into the discharge path of the battery cell.

[0018] In this embodiment, the bristles of multiple static electricity removal components extend into the discharge path of the battery cells, which can ensure that the brushes contact the battery cells at different positions, making the static electricity removal more reliable.

[0019] In a possible embodiment, the material tray includes a bottom plate and a plurality of columns. The bottom plate has a bearing surface for bearing the stacked battery cells. The plurality of columns are respectively connected to the material tray, and the plurality of columns are sequentially spaced around the periphery of the battery cells. The static electricity removal component is connected to the columns and is located above the battery cells stacked on the top layer, so that the discharge path of the battery cells passes through the static electricity removal component.

[0020] This embodiment ensures that even if the removed battery cells have separator paper stuck to the lower surface due to static electricity, the static electricity on the battery cells can be removed by the static electricity removal component when the battery cells pass through the static electricity removal component during the unloading process, causing the separator paper to fall off the lower surface of the battery cells due to its own weight and return to the material tray, ensuring that the battery cells after being removed are not stuck to the separator paper.

[0021] In a possible implementation, the static electricity removal component includes a brush. The brush includes a brush handle and bristles, one end of the brush handle is connected to the column, and the other end is provided with bristles; the bristles are made of a flexible conductive material, and the free ends of the bristles extend into the discharge path of the battery cell.

[0023] In a possible embodiment, the brush handle includes a mounting section and a bristle section connected to each other, and the bristles are arranged on the bristle section. The mounting section is provided with a mounting hole for matching with a fastener so that the mounting section is fixedly connected to the column; the mounting hole is a strip hole extending in a direction parallel to the battery cell. The mounting section and the bristle section are respectively arranged parallel to the battery cell, and the bristle section is bent relative to the mounting section.

[0024] In this embodiment, the installation position of the installation section on the column can be adjusted, thereby adjusting the relative position of the bristles and the battery sheet.

[0025] In a possible implementation, the brush handle is provided with an air blowing channel, which includes an air inlet and an air outlet, wherein the air inlet is provided on a surface of the brush handle facing away from the bristles, and the air outlet is arranged in a direction parallel to the panel surface of the battery cell.

[0026] In this embodiment, the blowing channel emits horizontal wind, which is beneficial to the separator paper and battery cells during discharge.

[0027] In a possible implementation, the paper separator removal device further includes a first blowing assembly, which is disposed on the outside of the material tray and is used for blowing air toward the material tray.

[0028] In this embodiment, the first blowing assembly can assist in separating the separator paper and the battery sheet.

[0029] In a possible implementation, the air outlet of the first blowing assembly is a strip-shaped hole extending along the stacking direction of the battery cells.

[0030] In this embodiment, the first blowing assembly can blow vertical air toward the battery cells and separator paper in the tray, which is conducive to separating the separator paper and the battery cells from each other.

[0031] In a possible implementation, there are multiple first blowing assemblies, and the multiple first blowing assemblies are distributed on two opposite sides of the periphery of the material tray.

[0032] In this embodiment, the first blowing assemblies arranged on both sides are conducive to blowing air to the battery cells and the separator paper from different directions, which is more conducive to separating the separator paper from the battery cells.

[0033] In a possible implementation, the paper separator removal device further includes a material picking assembly for picking up the battery cell and driving the battery cell to move out of the material tray along the material discharging path. The material picking assembly is configured to pick up the battery cell, move it to the static electricity removal assembly, pause, and then move out of the material tray.

[0034] In this embodiment, the material picking component can conveniently pick up the battery cells, and through the pause, it can ensure that the static electricity on the battery cells and separators (if adhered) is fully removed by the static electricity removal component to ensure that the battery cells and separators are reliably separated.

[0035] In a possible embodiment, the interleaving paper removal device further includes a material picking assembly, a paper picking assembly and a driving assembly. The material picking assembly is used to pick up battery cells from a material tray. The paper picking assembly is used to pick up interleaving paper from a material tray; the paper picking assembly and the material picking assembly are spaced from each other along a first direction; the driving assembly has an output end. Among them, the material picking assembly is connected to the output end, and is used to move between a first position and a second position driven by the output end. The paper picking assembly is connected to the output end to move synchronously with the material picking assembly, and is used to move between a second position and a third position driven by the output end, and when the material picking assembly is in the first position, the paper picking assembly is in the second position, and when the material picking assembly is in the second position, the paper picking assembly is in the third position. The third position is used to collect the removed interleaving paper, the second position is where the material tray is located, and the first position is used to place the battery cells after the interleaving paper is removed.

[0036] In this embodiment, the paper picking assembly and the material picking assembly are displaced synchronously, so that the operation rhythm and separation efficiency can be improved.

[0037] In a possible implementation, the first position, the second position and the third position are sequentially arranged along the first direction. The driving assembly is a linear driving member, which is used to drive the paper picking assembly and the material picking assembly to synchronously perform linear displacement along the first direction.

[0038] In this embodiment, the linear displacement arrangement is convenient and the movement is fast, which is conducive to ensuring a faster working rhythm.

[0039] In a possible implementation, a conveyor belt is provided at the first position for carrying and / or transporting the battery cells after the separator paper is removed; and / or a separator paper collection box is provided at the third position for collecting the removed separator paper.

[0040] In this embodiment, a conveyor belt is provided to facilitate the transportation of battery cells to subsequent processes; and a separator paper collection box is provided to facilitate the collection of removed separator papers for reuse or centralized treatment.

[0041] In a possible embodiment, the paper collecting box includes a bottom wall plate, a first side wall plate, and a second side wall plate. The bottom wall plate has a first edge and a second edge, the first edge and the second edge are a set of adjacent edges, and the first edge and the second edge intersect at a corner point. The first side wall plate is connected to the first edge, and the second side wall plate is connected to the second edge. The bottom wall plate is tilted relative to the direction of gravity, and the corner point is the lowest point of the bottom wall plate.

[0042] The provision of the separator paper collection box in this embodiment facilitates the removed separator papers to be neatly stacked in the separator paper collection box.

[0043] In a possible implementation, the bottom wall plate further has a third side and a fourth side. The first side, the second side, the third side and the fourth side are sequentially connected to form a quadrilateral. The bottom wall plate is provided with a first notch recessed from the third side, and the bottom wall plate is provided with a second notch recessed from the fourth side.

[0044] In this embodiment, the first notch and the second notch can facilitate taking out the separator paper collected in the separator paper collection box.

[0045] In a possible implementation, the paper picking assembly includes a first lifting cylinder and a first picking member, and the first lifting cylinder is transmission-connected to the first picking member to drive the first picking member to lift and lower to pick up or put down the separator paper.

[0046] In this embodiment, the paper picking assembly facilitates picking up the spacer paper.

[0047] In a possible implementation, the paper separator is provided with a notch. The paper picking assembly is further provided with a second blowing assembly for blowing air toward the notch. The second blowing assembly is transmission-connected to the first lifting cylinder for synchronously lifting and lowering with the first picking member under the drive of the first lifting cylinder.

[0048] In this embodiment, the second blowing assembly can blow air toward the middle of the battery cells and the separator paper stacked on the tray. The arrangement position of the blowing pipe corresponds to the gap on the separator paper, so that the airflow applies downward pressure to the battery cells, thereby separating the battery cells from the separator paper.

[0049] In a possible implementation, the material picking assembly includes a second lifting cylinder and a second picking member, and the second lifting cylinder is transmission-connected to the second picking member to drive the second picking member to lift and lower to clamp or put down the battery cell.

[0050] In this embodiment, the material picking assembly facilitates picking up or putting down the battery cells.

[0051] In a possible implementation, the static electricity removal component is configured to be suspended relative to the uppermost stacked battery cell.

[0052] In this embodiment, the suspended static electricity removal component can facilitate the removal of static electricity from each battery cell and separator paper when they are moved out along the discharge path, thereby facilitating the separation of the battery cells and separator paper from each other.

[0053] In a possible implementation, the paper separator removal device further comprises an elastic member. The static electricity removal component comprises conductive bristles, which are flexible bristles; the elastic member elastically presses the static electricity removal component so that the bristles elastically press against the upper surface of the battery sheet stacked at the uppermost position.

[0054] In this embodiment, when the battery cells are removed one by one, the brush can be forced downward by the elastic member so that the bristles always remain pressed against the battery cells stacked on the top layer, ensuring continuous static electricity removal operation.

[0055] In a possible implementation, the static electricity removal component includes an ion wind generator, which is used to blow ion wind toward the discharge path of the battery cells to remove static electricity on the battery cells and / or separator paper passing through.

[0056] In this embodiment, the ion wind generator can achieve non-contact static electricity removal.

[0058] The photovoltaic cell processing equipment provided in this embodiment can remove the separator paper by using the aforementioned separator paper removal device, thereby ensuring that the separator paper will not stick to the cell during printing, thereby causing the printing operation to be invalid, thereby ensuring the reliability of cell production.

DETAILED DESCRIPTION

[0076] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0077] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may also be a centered element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may also be a centered element. When an element is considered to be "set on" another element, it may be directly set on the other element or there may also be a centered element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0078] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present application. The terms used herein in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0079] Some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0080] Example

[0081] See also Figure 1 In this embodiment, the cell 200 is an important part of the photovoltaic solar module. For example, in a back contact cell, the electrodes are arranged on the back P1, and the front P2 is an anti-reflection passivation film layer. The electrodes of the cell are arranged on the back P1 of the cell to reduce the shielding of the electrodes on the front P2 of the cell, thereby improving the photoelectric conversion efficiency of the cell. The anti-reflection passivation film layer on the front P2 is used to reduce the reflection of the light beam, thereby improving the photoelectric conversion efficiency.

[0082] See also Figure 2 During the production process, the battery cells 200 need to be stacked together after the sorting process. In order to prevent the front side P2 and the back side P1 of adjacent battery cells 200 from directly contacting and abrading each other and causing scratches on the battery cells 200, a feasible method is to place a separator 300 between adjacent battery cells 200 to separate the adjacent battery cells 200. Figure 2 In the embodiment, the three battery cells 200 and the top and bottom of the stacked battery cells 200 are all padded with separators 300. The stacked battery cells 200 are also convenient for storage and packaging and transportation.

[0083] See also Figure 3 In this embodiment, the separator 300 is a sheet structure with a relatively thin thickness (such as a thickness less than 0.1 mm). The material of the separator 300 can be paper, plastic sheet or other materials that can separate the battery cells 200, which is not limited here.

[0084] Optionally, a notch K1 is provided in the middle of the separator 300, and there may be one or more notches K1. The notch K1 provided on the separator 300 can facilitate the separation of the separator 300 from the battery cell 200 by blowing air, which will be further described below. Figure 3 As shown in FIG. 1 , the notch K1 may include two inner and outer circles, the inner notch K1 has a smaller aperture, and the outer notch K1 has a larger aperture. The distribution of the notch K1 may also be appropriately set as required, which is not limited here.

[0085] Figure 2The battery cells 200 are separated by the separator paper 300, which can protect the battery cells 200 and / or facilitate packaging and transportation. However, when the stacked battery cells 200 are unpacked and used again, the battery cells 200 and the separator paper 300 are squeezed against each other during the packaging and storage of the entire stack of battery cells 200, and the air between the battery cells 200 and the separator paper 300 is discharged to form a negative pressure, making it difficult to separate the two. In addition, the mutual squeezing and friction between the battery cells 200 and the separator paper 300 will also generate static electricity, causing the battery cells 200 and the separator paper 300 to adhere to each other.

[0086] In this way, at the loading point of a printing press or other processing equipment, the battery cell 200 and the separator paper 300 may not be effectively separated due to static electricity and / or negative pressure, which may affect subsequent processing, cause equipment alarms or damage the battery cell 200, and reduce equipment efficiency and production line yield.

[0087] A lateral wind knife is arranged outside the material tray to achieve separation by blowing air from the side to the battery cells and separator paper in the material tray. However, it is found in practice that when only this solution is adopted, the wind from the lateral wind knife has difficulty entering the middle position between the battery cells and the separator paper, resulting in that the middle position between the battery cells and the separator paper cannot be effectively separated.

[0088] Figure 4 3D view of the paper separator removal device 100 in this embodiment (the figure additionally shows the stacked battery cells 200 and paper separators 300 ).

[0089] See also Figure 4 This embodiment provides a paper separator removal device 100, which can effectively separate the mutually adhered battery cells 200 and paper separators 300, ensure the normal loading of the battery cells 200, reduce the production line failure rate, and improve the production line yield, which will be illustrated below.

[0090] In this embodiment, the paper separator removal device 100 includes a material tray 50 , a paper separator collection box 10 , a battery cell carrier 20 and a manipulation mechanism 30 .

[0091] The material tray 50 is used to carry materials, namely, a plurality of stacked battery cells 200 (adjacent battery cells 200 are separated by separators 300). The operating mechanism 30 can pick up the battery cells 200 from the material tray 50 and place them on a battery cell carrier 20 (such as a conveyor belt 21), and pick up the separators 300 from the material tray 50 and place them on a separator collection box 10, thereby achieving separation of the battery cells 200 and the separators 300.

[0092] The paper separator removal device 100 of this embodiment further includes a static electricity removal component 40 , which is located on the discharge path S1 of the battery cell 200 and is used to remove static electricity from the battery cell 200 and / or the paper separator 300 discharged through the discharge path S1 .

[0093] Optionally, the material tray 50 , the paper collecting box 10 and the cell carrier 20 of the paper removing device 100 can be respectively mounted on a mounting platform 101 to ensure the relative positions of the components. The operating mechanism 30 can be suspended above the mounting platform 101 .

[0094] Figure 5 FIG. 4 shows a perspective view of the material tray 50 of this embodiment when carrying stacked battery cells 200. Figure 6 for Figure 5 Top view of the .

[0095] See also Figure 5 and Figure 6 In this embodiment, the material tray 50 includes a bottom plate 51 and a plurality of columns 52 .

[0096] The bottom plate 51 has a bearing surface P3 for bearing the stacked battery cells 200 and the separator paper 300. Optionally, the bottom plate 51 in this embodiment is a substantially rectangular plate structure, whose length and width (or side length) are greater than the corresponding battery cell 200 to fully support the battery cell 200.

[0097] A plurality of columns 52 are respectively connected to the material tray 50, and the plurality of columns 52 are sequentially spaced around the outer periphery of the battery cell 200. The lower end of the column 52 is connected to the bottom plate 51, and the upper end extends upward (i.e., the stacking direction Z of the battery cell 200 and the separator paper 300). In this way, the bottom plate 51 and the plurality of columns 52 together enclose an internal space Q1 for accommodating the battery cell 200 and the separator paper 300. In this embodiment, the discharge path S1 refers to the path of the battery cell 200 leaving the material tray 50. For example, for the material tray 50 in this embodiment, the discharge path S1 of the battery cell 200 includes a section along the vertical upward direction, which is located within the internal space Q1 enclosed by the plurality of columns 52. The height of the column 52 can be determined according to the total height of the stacked battery cells 200 and the separator paper 300 or set to be adjustable.

[0098] Optionally, for the rectangular bottom plate 51 and the battery cell 200, there are eight columns 52 in total in this embodiment, two columns are arranged on each of the four sides of the bottom plate 51, and the two columns 52 on each side are spaced apart to form a first gap f1. A second gap f2 exists between two adjacent columns 52 on two adjacent sides of the bottom plate 51.

[0099] Optionally, each side of the outer periphery of the bottom plate 51 is provided with a concave groove C1, and the bottom of the column 52 fits in the groove C1. In this way, the connection position of the column 52 in the groove C1 can be adjusted to adapt to battery cells 200 of different panel sizes, thereby improving the application range of the tray 50.

[0100] Continue to see Figure 5 and Figure 6In this embodiment, the static electricity removal assembly 40 is connected to the column 52 and is located above the battery cells 200 stacked on the top layer, so that the discharge path S1 of the battery cells 200 passes through the static electricity removal assembly 40. In this way, even if the battery cells 200 taken out are adhered to the separator paper 300 on the lower surface due to static electricity, when the battery cells 200 pass through the static electricity removal assembly 40 during the discharge process, the static electricity on the battery cells 200 can be removed by the static electricity removal assembly 40, causing the separator paper 300 to fall off from the lower surface of the battery cells 200 due to its own weight and return to the material tray 50, ensuring that the battery cells 200 taken out are not adhered to the separator paper 300.

[0101] Among them, the height h1 of the static electricity removal component 40 from the battery cell 200 stacked on the top layer can be set as needed, for example, set to 5cm≥h1≥1cm, so as to ensure that the picked-up battery cell 200 is upwardly separated from the underlying object (such as the battery cell 200 or the separator 300 of the next layer) by a certain distance before the static electricity removal operation is performed. At the same time, the static electricity removal position is not too high, so as to ensure that the separator 300 that falls after static electricity removal can basically fall back to its original position.

[0102] In this embodiment, optionally, the static electricity removal component 40 includes a brush 40 a , the number of which can be set as needed. For example, as shown in the figure, there are four brushes 40 a , which are respectively arranged at the four corners of the battery cell 200 .

[0103] Of course, in other embodiments, the battery cell 200 may also be in other shapes, and correspondingly, the plurality of brushes 40 a may be distributed at the plurality of corners of the battery cell 200 .

[0104] The brush 40a includes a brush handle 41 and bristles 42. One end of the brush handle 41 is connected to the column 52 and is arranged at intervals outside the discharge path S1 of the battery cell 200, and the other end is provided with bristles 42. The bristles 42 are conductive structures 42a made of flexible conductive materials (such as carbon fibers, thin metal or non-metallic wires), and at least part of the bristles extend into the discharge path S1 of the battery cell 200, for example, the free ends of the bristles 42 extend into the discharge path S1 of the battery cell 200. In this way, when the battery cell 200 is discharged along the discharge path S1, it will touch the bristles 42 upwards and conduct the charge on it to the bristles 42, thereby eliminating the static electricity between the battery cell 200 and the separator paper 300, and eliminating the static adsorption between the separator paper 300 and the battery cell 200. At the same time, due to the flexibility of the bristles 42, when the battery cell 200 continues to be discharged upward, the bristles 42 can be deformed and make way. After the battery cell 200 passes, the bristles 42 can return to the initial state to ensure the removal of static electricity when the next battery cell 200 is discharged.

[0105] The number and distribution of the bristles can be set as needed. In this embodiment, when installed on the column 52, the bristles have at least multiple rows distributed vertically to ensure that the battery cell 200 contacts more bristles when passing by, thereby ensuring the static electricity removal effect.

[0106] In this embodiment, optionally, the brush handle 41 includes a mounting section 411 and a bristle section 412 connected to each other, and the bristles 42 are arranged on the bristle section 412. The bristles 42 can be distributed on a side surface of the bristle section 412. The mounting section 411 is provided with a mounting hole K2 for matching a fastener (such as a screw) to fix the mounting section 411 to the column 52. Optionally, the mounting hole K2 is a strip hole extending in a direction parallel to the plate surface (front P2 or back P1) of the battery cell 200, so that the mounting position of the mounting section 411 on the column 52 can be adjusted.

[0107] Continue to see Figure 5 and Figure 6 In this embodiment, the mounting section 411 and the bristle section 412 are respectively arranged parallel to the battery cell 200, that is, the extension direction of the bristles 42 is parallel to the plane where the battery cell is located.

[0108] The bristle section 412 is bent relative to the mounting section 411 (also shown in Figure 7 and Figure 8 ), for example, as shown in the figure, the bristle section 412 is bent approximately 30-60° (such as 45°) relative to the mounting section 411. In this way, when the mounting position of the mounting section 411 on the column 52 is adjusted along the extension direction of the mounting section 411, the bristles 42 can be adjusted to enter the discharge path S1 of the battery cell 200 and / or the separator 300 more or less. By comparison Figure 7 and Figure 8 The bending arrangement enables the brush handle 41 to be connected to the outside of the column 52 (located outside the internal space Q1) so that the bristles 42 can extend from the second gap f2 between the adjacent columns 52 at the corner into the internal space Q1 of the tray 50 and enter the discharge path S1 of the battery cell 200.

[0109] Thus, as the installation position of the installation section 411 changes, the projection area of ​​the bristles 42 extending into the discharge path S1 of the battery cell 200 (or the separator 300) on the plate surface of the battery cell 200 will also change accordingly. Thus, the user can adjust the installation position of the installation section 411 of the brush 40a appropriately to adjust the area of ​​the bristles 42 that can act on the battery cell, while ensuring the anti-static effect (more bristles 42 are required to contact the battery cell 200) and avoiding excessive obstruction and / or friction of the bristles 42 on the battery cell 200 (less bristles 42 are required to block the battery cell 200).

[0110] In addition, the four brushes 40a arranged at the four corners in this embodiment can also apply downward pressure to the four corners of the separator paper 300 padded on the battery cell 200. Since the separator paper 300 is soft in texture and is bent, the gap between the separator paper 300 and the battery cell 200 is further increased, which is conducive to separating the battery cell 200 from the separator paper 300.

[0111] See also Figure 7 and Figure 8 In this embodiment, the brush handle 41 is provided with a blowing channel T1, and the blowing channel T1 includes an air inlet K3 and an air outlet K4, wherein the air inlet K3 is provided on a surface of the brush handle 41 facing away from the bristles 42, and the air outlet K4 is provided on the bristle 42 side of the brush handle 41. Optionally, the air inlet K3 and the air outlet K4 are both provided in the bristle section 412, and the air outlet K4 is arranged in the arrangement range of the bristles 42 along a direction parallel to the plate surface of the battery cell 200.

[0112] The brush 40a can allow compressed air to pass through the air inlet K3, and the gas is blown out from the air outlet K4 to form cross wind (i.e., wind parallel to the surface of the battery cell 200). The brushes 40a at the four corners can blow air to the four corners of the battery cell 200 and the separator paper 300 respectively, thereby separating the battery cell 200 from the separator paper 300.

[0113] In other embodiments, the brush 40a with bristles 42 serving as the conductive structure 42a can also be replaced with other conductive structures 42a, such as flexible conductive films, conductive springs, etc., without limitation herein. It is only necessary to ensure that the conductive structure 42a of the static electricity removal component 40 is located on the discharge path S1 of the battery cell 200 and is able to contact the passing battery cell 200 and / or separator paper 300 to remove static electricity on the battery cell 200 and / or separator paper 300.

[0114] In other embodiments, the static electricity removal component 40 may also remove static electricity in a non-contact manner. For example, the static electricity removal component 40 includes an ion wind generator, which is used to blow ion wind toward the discharge path S1 of the battery cell 200 to remove static electricity on the passing battery cell 200 and / or the separator paper 300. This solution still adopts the method of setting the ion wind generator as the static electricity removal component 40 on the discharge path S1 of the battery cell 200 (for example, arranged at intervals above the battery cell 200 stacked on the top layer), rather than setting it on one side of the tray 50 directly corresponding to the battery cell 200 and the separator paper 300 in the tray 50.

[0115] The paper separator removal device 100 in the embodiment of the present application has a static electricity removal component 40 (such as a brush 40a with a conductive structure 42a, an ion wind generator or other device capable of removing static electricity) disposed on the discharge path S1 of the battery cell 200. During the discharge process, if the battery cell 200 is adhered to the paper separator 300 due to static electricity, the static electricity on the battery cell 200 and the paper separator 300 can be removed by the static electricity removal component 40 when passing through the static electricity removal component 40, which helps to make the adhered paper separator 300 fall due to its own weight, thereby separating the paper separator 300 and the battery cell 200 from each other, which helps to ensure the reliability of the removal of the paper separator 300.

[0116] In addition, the static electricity removal component 40 disposed on the discharge path S1 of the battery cell 200 can also remove static electricity generated during discharge (such as static electricity generated by the charge conducted from the operating mechanism 30 to the battery cell 200 or the separator paper 300 during discharge).

[0117] In contrast, if the static electricity removal device can only remove static electricity from battery cells placed on the tray, it is more difficult to remove static electricity because the battery cells in the tray are stacked together. As a result, during the unloading process, there may still be problems with the separator paper being difficult to separate from the battery cells due to residual static electricity on the battery cells or separator paper. The reliability of separator paper removal is relatively low.

[0118] See again Figure 5 and Figure 6 In this embodiment, the paper separator removal device 100 also includes a first blowing component 60, which is a lateral wind knife 60a. The first blowing component 60 is arranged on the outer side of the material tray 50, and is used to blow air toward the material tray 50, and the air outlet K5 of the first blowing component 60 is a strip hole extending along the stacking direction Z of the battery cells 200, so as to blow vertical air toward the battery cells 200 and the paper separators 300 in the material tray 50, which is conducive to separating the paper separators 300 and the battery cells 200 from each other.

[0119] Optionally, there are multiple first blowing assemblies 60, and the multiple first blowing assemblies 60 are distributed on opposite sides of the outer circumference of the material tray 50. Figure 5 and Figure 6 As shown, there are four first blowing assemblies 60 , and the four first blowing assemblies 60 are distributed in pairs on two opposite sides of the outer circumference of the material tray 50 .

[0120] Fig. 9 Shows Figure 4 A perspective view of the operating mechanism 30 of the separator paper removing device 100 .

[0121] See also Fig. 9 and Figure 4 In this embodiment, the operating mechanism 30 of the paper separator removal device 100 includes a driving component 31, a material picking component 33 and a paper picking component 32.

[0122] The material picking assembly 33 is used to pick up the battery cell 200 from the material tray 50, drive the battery cell 200 to move out of the material tray 50 along the material discharging path S1, and place the battery cell 200 on the battery cell carrier 20; the paper picking assembly 32 is used to pick up the separator 300 from the material tray 50, and place the separator 300 in the separator collection box 10; the driving assembly 31 is used to drive the material picking assembly 33 and the paper picking assembly 32 to move. In this way, the stacked battery cells 200 and separators 300 can be separated from each other, and the separators 300 can be removed and the battery cells 200 can be loaded one by one.

[0123] In this embodiment, the operating mechanism 30 optionally includes a controller 34, which is electrically connected to the material picking assembly 33 and can control the material picking assembly 33 to pause in the air for a set time (such as 1 to 3 seconds) when picking up the battery cell 200 and moving it to the static electricity removal assembly 40, and then move out of the material tray 50. Through this pause, it can be ensured that the static electricity on the battery cell 200 and the separator 300 (if adhered) is fully removed by the static electricity removal assembly 40, so as to ensure that the battery cell 200 and the separator 300 are reliably separated.

[0124] Among them, the driving component 31 can be a linear driving component 31a (such as a linear servo battery, a linear cylinder, a screw nut driving mechanism, etc.), which is used to drive the paper picking component 32 and the material picking component 33 to synchronously perform linear displacement along the first direction X, and the first direction X is along a straight line direction.

[0125] The paper picking assembly 32 includes a first lifting cylinder 321 and a first picking member 322. The first lifting cylinder 321 is installed at the output end 311 of the driving assembly 31 and is transmission-connected to the first picking member 322, and is used to drive the first picking member 322 to rise and fall to pick up or put down the separation paper 300. The first picking member 322 can be a clamp or other grabbing structure.

[0126] Optionally, the paper picking assembly 32 is further provided with a second blowing assembly 70 (for example, a blowing pipe 71) for blowing air toward the notch K1 (see Figure 2 or Figure 3 ) The second blowing assembly 70 can blow air toward the middle of the battery cells 200 and the separator paper 300 stacked on the tray 50. The arrangement position of the blowing pipe 71 corresponds to the notch K1 on the separator paper 300, so that the airflow applies downward pressure to the battery cells 200, thereby separating the battery cells 200 from the separator paper 300. The number of the blowing pipes 71 can be one or more. For example, in this embodiment, there are four blowing pipes 71, and the four blowing pipes 71 correspond to the notches K1 of the four outer circles.

[0127] Optionally, the second blowing assembly 70 is transmission-connected to the first lifting cylinder 321 , and is used to be lifted and lowered synchronously with the first picking member 322 under the drive of the first lifting cylinder 321 , so as to facilitate blowing at a position close to the partition paper 300 , thereby facilitating separation of the partition paper 300 .

[0128] The material picking assembly 33 includes a second lifting cylinder 331 and a second picking member 332. The second lifting cylinder 331 is installed at the output end 311 of the driving assembly 31 and is transmission-connected to the second picking member 332, and is used to drive the second picking member 332 to rise and fall, so as to clamp or put down the battery cell 200. The second picking member 332 can adopt a negative pressure suction cup or other grasping structure.

[0129] In this embodiment, the output end 311 of the driving assembly 31 is provided with a connecting bar 312 extending along the first direction X, and the connecting bar 312 is located above the material tray 50. The material picking assembly 33 and the paper picking assembly 32 are connected to the connecting bar 312 at intervals in the first direction X, so that they can be synchronously displaced along the first direction X with the connecting bar 312. Among them, the material picking assembly 33 is displaced between the first position D1 and the second position D2 under the drive of the connecting bar 312; the paper picking assembly 32 and the material picking assembly 33 are synchronously displaced and displaced between the second position D2 and the third position D3 under the drive of the connecting bar 312. In this embodiment, the first direction X is along a straight line, and the first position D1, the second position D2 and the third position D3 are sequentially arranged along the first direction X, and the spacing between the first position D1 and the second position D2 is equal to the spacing between the second position D2 and the third position D3.

[0130] When the material taking assembly 33 is located at the first position D1, the paper taking assembly 32 is located at the second position D2 (eg, Fig. 9 In the state in the middle), when the material taking component 33 is located at the second position D2, the paper taking component 32 is located at the third position D3. The third position D3 is the location of the paper collecting box 10, which is used to collect the removed paper 300; the second position D2 is the location of the material tray 50, and the first position D1 is the location of the battery cell carrier 20 (for example, a conveyor belt 21), which is used to carry and / or transport the battery cell 200 after the paper 300 is removed.

[0131] The operation rhythm can be improved by synchronously displacing the paper picking assembly 32 and the material picking assembly 33.

[0132] The working process of the paper separator removal device 100 of this embodiment is briefly introduced below.

[0133] In the first state, the connecting bar 312 of the driving assembly 31 is located near the first position D1, the material picking assembly 33 corresponds to the battery cell carrier 20 at the first position D1, and the paper picking assembly 32 corresponds to the material tray 50 at the second position D2 and grabs the separator paper 300;

[0134] In the process from the first state to the second state, the connecting bar 312 of the driving assembly 31 is displaced along the first direction X to the side close to the third position D3, thereby driving the material taking assembly 33 to move to the material tray 50 corresponding to the second position D2, and driving the paper taking assembly 32 to move to the paper separation collection box 10 corresponding to the third position D3;

[0135] In the process from the second state to the third state, the material taking component 33 picks up a battery cell 200 from the material tray 50 downwards, and the paper taking component 32 releases the separator paper 300 thereon downwards to the separator paper collecting box 10;

[0136] In the process from the third state to the fourth state, the material taking component 33 drives the battery cell 200 to rise along the discharge path S1 and leave the material tray 50, and the paper taking component 32 rises and leaves the paper separation collection box 10; in this process, when the material taking component 33 drives the battery cell 200 to rise, it can pause for a set time (such as 1 to 3 seconds) at the height of the static removal component 40 to remove static electricity and / or the air blowing brush 40a blows air to ensure that the adhered paper separation 300 (if any) is separated from the battery cell 200 and falls back into the material tray 50;

[0137] In the process from the fourth state to the fifth state, the connecting bar 312 of the driving assembly 31 moves back along the first direction X to the side close to the first position D1, thereby driving the material picking assembly 33 and the battery cell 200 picked up by it to move to the battery cell carrier 20 corresponding to the first position D1, and driving the paper picking assembly 32 to move to the material tray 50 corresponding to the second position D2;

[0138] In the process from the fifth state to the sixth state, the material taking component 33 places the battery cell 200 on the battery cell carrier 20 downward, and the paper taking component 32 picks up a separator paper 300 from the material tray 50 downward;

[0139] In the process of returning from the sixth state to the first state, the material taking assembly 33 rises and leaves the battery cell carrier 20. When the battery cell carrier 20 is a conveyor belt 21, it can transfer the battery cell 200 to the next process for processing. The paper picking assembly 32 drives the grabbed spacer paper 300 to rise and leave the material tray 50; to ensure that the spacer paper 300 is successfully grabbed, the paper picking assembly 32 can blow air to the gap K1 of the spacer paper 300 through its second blowing assembly 70 (for example, a blowing pipe 71) during the paper picking process to promote the separation of the spacer paper 300 and the battery cell 200 thereunder; in addition, in the process of the paper picking assembly 32 driving the grabbed spacer paper 300 to rise and leave the material tray 50, it can also pause for a set time (such as 1s) at the height where the static electricity removal assembly 40 is located to eliminate the static electricity between the spacer paper 300 and the battery cell (if any) adhered thereto, which is conducive to the battery cell 200 adhered thereto below the spacer paper 300 falling due to its own weight, thereby preventing the battery cell 200 from being mistakenly grabbed and placed in the spacer paper collection box 10;

[0140] By continuing to cycle the above process, the operations of continuously taking out materials and removing the separator paper 300 can be realized until the operation is completed. The battery cells 200 are sent to the battery cell carrier 20 one by one, and can be loaded by other equipment (such as a robot) to the next process (such as printing of the battery cells 200), and the separator paper 300 is collected in the separator paper collection box 10 for reuse or centralized processing.

[0141] During the entire cycle, the first blowing assembly 60 (such as the lateral wind knife 60 a ) can maintain a blowing state to promote the separation of the separator paper 300 and the battery cell 200 .

[0142] The paper separator removal device 100 in this embodiment may further include a detection component 22 (see Figure 4 ), for detecting whether the lower surface of the battery cell 200 placed on the battery cell carrier 20 is still covered with the separator 300. The detection component 22 may include a color sensor, which determines whether the battery cell 200 is covered with the separator 300 by color recognition.

[0143] For example, in some embodiments, the battery cell 200 is blue, the separator paper 300 is a different color (such as white), and the color sensor faces the bottom surface of the battery cell carrier 20 and corresponds to the surface of the battery cell carrier 20 that supports the battery cell 200.

[0144] If the color sensor recognizes that the color of the object carried by the battery cell carrier 20 is blue, it is determined that the bottom of the battery cell 200 is not covered with the separator paper 300. At this time, the conveyor belt 21 serving as the battery cell carrier 20 can be instructed to transport the battery cell 200 to the subsequent process; if the color sensor recognizes that the color of the object carried by the battery cell carrier 20 is white, it is determined that the bottom of the battery cell 200 is covered with the separator paper 300, and the battery cell 200 and the covered separator paper 300 need to be driven back to the material tray 50 by the material picking component 33, and the separator paper 300 removal step is performed again, or the separator paper 300 can be removed manually.

[0145] In other embodiments, the color sensor may also be disposed above the cell carrier 20 and corresponds to the upper surface of the cell carrier 20 that carries the cell 200. In this way, the color sensor may be used to detect whether the upper surface of the cell 200 is covered with the separator 300.

[0146] In this embodiment, the detection component 22 can be configured only during the testing phase of the paper spacer removal device 100. After a period of testing, if the test results show that the paper spacer removal device 100 can reliably and effectively remove the paper spacer 300, the detection component 22 can be removed or disabled to save cost and time.

[0147] Fig.10A separator paper collection box 10 of this embodiment is shown (the separator paper 300 is shown by dotted lines in the figure), which can conveniently collect the separator paper 300 in the above process.

[0148] See also Fig.10 The paper collecting box 10 includes a bottom wall plate 13, a first side wall plate 11 and a second side wall plate 12. The bottom wall plate 13 has a first side L1 and a second side L2, the first side L1 and the second side L2 are a set of adjacent sides, and the first side L1 and the second side L2 intersect at a corner point D4. The first side wall plate 11 is connected to the first side L1, and the second side wall plate 12 is connected to the second side L2. The bottom wall plate 13 is tilted relative to the gravity direction G (in this embodiment, the stacking direction of the battery cells 200 is parallel to the gravity direction G), and the corner point D4 is the lowest point of the bottom wall plate 13.

[0149] In this way, when the paper picking assembly 32 places the picked up spacer paper 300 in the spacer paper collection box 10, the spacer paper 300 can slide down along the inclined bottom wall plate 13, so that the spacer paper 300 is respectively attached to the first edge L1 and the second edge L2 with a group of adjacent edges, ensuring that multiple spacer papers 300 are neatly stacked in the spacer paper collection box 10, which is convenient for secondary use or centralized processing.

[0150] Optionally, the bottom wall plate 13 further has a third side L3 and a fourth side L4, and the first side L1, the second side L2, the third side L3 and the fourth side L4 are sequentially connected to form a quadrilateral (such as a rectangle). The bottom wall plate 13 is provided with a first notch K6 recessed from the third side L3, and the bottom wall plate 13 is provided with a second notch K7 recessed from the fourth side L4. The first notch K6 and the second notch K7 facilitate the removal of the separator 300.

[0151] In this embodiment, the paper separator removal device 100 can separate the paper separator 300 and the battery cell 200 by being synchronously displaced, which can effectively improve the equipment cycle of the paper separator removal device 100. The equipment production capacity is increased from the original fastest 1.2s / pcs to 0.9s / pcs, which effectively improves the production cycle and improves equipment utilization.

[0152] See also Fig.11 In another embodiment, the vertical position of the static electricity removal component 40 (such as the brush 40a) on the column 52 is not fixed and cannot be adjusted. Fig.11 In this embodiment, the static electricity removal component 40 is configured to be suspended relative to the battery cell 200 stacked at the uppermost position, and the suspension distance is adjustable. For example, a strip groove K8 is provided on the column 52, so that the static electricity removal component 40 can adjust the vertical position relative to the column 52, which is conducive to removing static electricity from the battery cell 200 at a suitable height.

[0153] See also Fig.12In another embodiment, the anti-static component 40 is also a brush 40a including conductive bristles 42, and the brush 40a is movably arranged along the vertical direction of the column 52 (for example, connected to the column 52 through a linear slide rail), and the paper removal device 100 also includes an elastic member 53, one end of the elastic member 53 is supported on a support portion 531 connected to the column 52, and the other end elastically presses the brush 40a, so that the bristles 42 of the brush 40a are elastically pressed against the upper surface of the battery cell 200 stacked at the uppermost position. Among them, the support portion 531 can be obtained by protruding from the top of the column 52 in a direction parallel to the battery cell 200, or it can be an additional component connected to the column 52. In this way, the bristles 42 can always maintain the anti-static operation on the battery cell 200 stacked on the uppermost layer. Specifically, the elastic member 53 is initially in a compressed state. As the battery cell 200 or separator paper 300 in the material tray 50 is removed, the elastic member 53 elastically stretches, thereby pushing the brush 40a downward to press against the upper surface of the next battery cell 200 or separator paper 300, thereby ensuring that the bristles 42 of the brush 40a remain in contact with the battery cell 200 or separator paper 300.

[0154] See also Fig.13 In another embodiment, the first position D1 (cell carrier 20), the second position D2 (material tray 50) and the third position D3 (paper collecting box 10) are arranged along an arc line L5, that is, the first direction X is changed to be along an arc line L5 instead of a straight line as described above. At this time, the driving component 31 can use a rotary driving component 31b (such as a rotary motor), which drives a swing arm 315 to rotate, and the end of the swing arm 315 is connected to an arc-shaped connecting bar 316, and the material picking component 33 and the paper picking component 32 are respectively connected to the arc-shaped connecting bar 316.

[0155] Fig.13 In the illustrated embodiment, the driving assembly 31 can also drive the material picking assembly 33 to move between the first position D1 and the second position D2, and synchronously drive the paper picking assembly 32 to move between the second position D2 and the third position D3, thereby realizing the separation of the battery cell 200 and the separator paper 300.

[0156] It should be noted that Fig.13 The components in the figure are shown in simplified diagrams and do not represent their actual shapes.

[0157] Fig.14 A three-dimensional diagram of a photovoltaic cell processing device 1000 in an embodiment of the present application is shown.

[0158] See also Fig.14 In this embodiment, the photovoltaic cell processing equipment 1000 includes a processing device 500 and the aforementioned paper separator removal device 100 .

[0159] The processing device 500 is used to process the battery cell 200 after the separator 300 is removed by the separator removing device 100. For example, the processing device 500 is a printer, which is used to print a pattern on the surface of the battery cell 200 after the separator 300 is removed.

[0160] The photovoltaic cell processing equipment 1000 uses the aforementioned spacer paper removal device 100 to remove the spacer paper 300, thereby ensuring that the spacer paper 300 will not stick to the cell 200 during printing, thereby causing the printing operation to be invalid, thereby ensuring the reliability of the production of the cell 200.

[0161] The above implementation modes are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the above preferred implementation modes, a person skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
