Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of electroplating and relates to an adjustable conductive brush and a horizontal electroplating device. Background Art
[0002] With the expansion and rapid development of the photovoltaic industry, the competition for solar photovoltaic products in the market is becoming increasingly fierce. In the solar photovoltaic industry, the horizontal electroplating process of battery cells is more important.
[0003] Horizontal electroplating technology is a method of placing the workpiece to be plated parallel to the surface of the electroplating solution for electroplating. It is roughly the same as the basic principle of ordinary electroplating. It includes a cathode and an anode. Generally, the cathode is used to contact the workpiece to be plated, and the anode is used to conduct electricity into the electroplating solution. In this way, an electrode reaction will occur in the electroplating solution after power is turned on. Under the action of the electric field, the metal ions in the electroplating solution migrate to the vicinity of the cathode to form a coating on the workpiece to be plated. Horizontal electroplating is easy to operate, suitable for a wide range of workpiece sizes, and is convenient for large-scale automated operations and closed operations. It has developed rapidly in recent years and is gradually moving towards a mature technology with higher quality and higher reliability.
[0004] In the existing horizontal electroplating equipment, the cathode includes a conductive brush with a conductive wire. After the conductive brush is fixed, the battery cell is energized by sliding the conductive wire to electroplate the battery cell. However, it is not easy to fix the conductive wire with the existing conductive brush, which will waste installation time. Moreover, the fixed conductive brush is usually only applicable to one type of battery cell. When the battery cell changes, such as changes in thickness, the conductive brush needs to be replaced to avoid scratching the battery cell. Therefore, the conductive brush-type horizontal electroplating equipment has poor application flexibility and is difficult to meet the diversified product needs.

[0073] The following is an explanation of the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.
[0074] It should be noted that the illustrations provided in this embodiment are only used to schematically illustrate the basic concept of the present invention. Therefore, the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.
[0075] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0076] See also Figure 1 The present embodiment provides an adjustable conductive brush, which includes an adjustment base 10, a rotation adjustment base 20, a crossbeam 30 and a conductive brush 40. The adjustment base 10 includes a first adjustment base and a second adjustment base that are correspondingly arranged, and the first adjustment base and the second adjustment base are provided with a horizontal adjustment hole 11 and a vertical adjustment hole 12; the rotation adjustment base 20 includes a first rotation adjustment base and a second rotation adjustment base that are correspondingly arranged, the first rotation adjustment base is connected to the first adjustment base and the connection position includes the vertical adjustment hole 12, and the second rotation adjustment base It is connected to the second adjustment base and the connection position includes the vertical adjustment hole 12, and the first rotation adjustment seat and the second rotation adjustment seat both have a rotation adjustment hole 21; the corresponding two ends of the beam 30 are respectively connected to the first rotation adjustment seat and the second rotation adjustment seat, and the connection position includes the rotation adjustment hole 21; the conductive brush 40 includes a conductive brush fixing portion 41 and a conductive brush comb tooth portion 42 connected to the conductive brush fixing portion 41, the conductive brush fixing portion 41 is fixed on the beam 30, and the conductive brush comb tooth portion 42 has an inclined angle with the horizontal plane.
[0077] Specifically, since the adjustment base 10, the rotation adjustment seat 20, the crossbeam 30 and the conductive brush 40 are interconnected, the position of the base 10 can be adjusted in the transverse direction through the transverse adjustment hole 11 to adjust the transverse position of the conductive brush 40; the position between the rotation adjustment seat 20 and the adjustment base 10 can be adjusted in the vertical direction through the vertical adjustment hole 12, thereby adjusting the vertical position of the conductive brush 40; the angle between the crossbeam 30 and the rotation adjustment seat 20 can be adjusted through the rotation adjustment hole 21, thereby adjusting the inclination angle between the conductive brush 40 and the horizontal plane.
[0078] Among them, Figure 2 When the conductive brush 40 is adjusted to have the inclined angle with the horizontal plane, the scratches of the conductive brush comb teeth 42 on the battery cell 60 can be reduced when the conductive brush 40 contacts the battery cell 60; the contact area between the conductive brush comb teeth 42 and the battery cell 60 can be increased to reduce the contact resistance; when the battery cell 60 is running at a high speed, the inclined angle is designed to reduce the resistance of the conductive brush comb teeth 42 to the battery cell 60 and prevent the battery cell 60 from slipping; in the inclined state, the deformation of the conductive brush comb teeth 42 can be reduced, so that the conductive brush comb teeth 42 can be easily restored to the original state, which can extend the service life of the conductive brush 40.
[0079] The adjustable conductive brush of the present embodiment can realize flexible control of the lateral position, vertical position and tilt angle of the conductive brush 40, and can be flexibly adjusted according to the requirements of the battery cell 60, thereby effectively avoiding scratches on the battery cell 60 and meeting the diversified needs of products.
[0080] As an example, the material of the conductive brush 40 may include pure titanium, pure copper, pure nickel or sputtering targets of these materials. The specific material can be selected according to needs.
[0081] As an example, a conductive brush pressing plate may be further included. The conductive brush pressing plate is located on the surface of the conductive brush fixing portion 41 and is fixedly connected to the crossbeam 30 .
[0082] Specifically, Figure 1 As shown, after the conductive brush fixing part 41 is fixed on the beam 30, the conductive brush pressing plate can be added to the surface of the conductive brush fixing part 41, so that the conductive brush pressing plate covers the conductive brush fixing part 41 and only the conductive brush comb teeth part 42 are exposed, thereby reducing the probability of deformation of the conductive brush 40 and extending the life of the conductive brush 40.
[0083] As an example, the conductive brushes 40 may be disposed on opposite sides of the beam 30 , and the conductive brushes 40 are correspondingly disposed to form a conductive brush group, wherein N groups of the conductive brush groups may be disposed on the beam 30 , and N≥2.
[0084] Specifically, Figure 1 to Figure 3 In this embodiment, the conductive brushes 40 are disposed on opposite sides of the beam 30, and two conductive brushes 40 are disposed in parallel on the same side of the beam 30, so that a total of four conductive brushes 40 are disposed on the beam 30, and two conductive brushes 40 disposed on opposite sides of the beam 30 form a group, so that one group of conductive brushes 40 contacts the same battery cell 60, thereby improving the stability of the battery cell 60 through four contact surfaces. In this embodiment, in order to improve production efficiency, two groups of conductive brushes are disposed on the same beam 30, so that two battery cells 60 can be synchronously processed at the same time, that is, the value of N is 2, but the value of N is not limited thereto, and may also be 1 or 3, etc.
[0085] As an example, the top end of the conductive brush comb-tooth portion 42 is preferably in an arc shape.
[0086] Specifically, the conductive brush comb teeth 42 may be subjected to a curling process or a bending process so that the end of the conductive brush comb teeth 42 is arc-shaped, thereby avoiding direct contact between the tip and the battery cell 60 and reducing damage to the conductive brush comb teeth 42 and / or the battery cell 60.
[0087] As an example, the inclined angle between the conductive brush comb teeth 42 and the horizontal plane may range from 30° to 80°.
[0088] Specifically, Figure 3 The tilt angle between the conductive brush comb teeth 42 and the horizontal plane can range from 30°, 60°, 70°, 80°, etc., and the tilt angle can be adjusted through the rotation adjustment hole 21 to expand the application range.
[0089] As an example, it is preferred that the inclination direction of the conductive brush comb portion 42 is consistent with the running direction of the battery cell 60. Figure 3 In the figure, the running direction of the battery cell 60 can be regarded as from left to right, and the inclination direction of the conductive brush comb teeth 42 is set to be inclined to the right, so that when the battery cell 60 contacts the conductive brush comb teeth 42, a good buffer can be formed to reduce the probability of damage to the battery cell 60 and / or the conductive brush comb teeth 42.
[0090] like Figure 2 and Figure 3This embodiment further provides a horizontal electroplating device, the horizontal electroplating device includes the adjustable conductive brush, and the horizontal electroplating device also includes an isolation slot 50, the isolation slot 50 includes:
[0091] A frame, the frame comprising a bottom plate 101, side plates and end plates connected to each other and forming a cavity with an opening, wherein the end plate is provided with a plating solution outlet adjacent to the bottom plate;
[0092] A corrugated adjustment plate, the top surface of which is corrugated, the corrugated adjustment plate is connected to the side plate, and the top surface of which is convexly arranged on the top surface of the side plate;
[0093] The end of the conductive brush comb-tooth portion 42 extends into the cavity and has a spacing with the corrugated adjustment plate in the lateral direction.
[0094] The horizontal electroplating device in this embodiment is combined with the adjustable conductive brush and the isolation groove 50 having the corrugated adjustment plate, which can effectively isolate the conductive brush 40 from the electroplating liquid, and the setting of the corrugated adjustment plate can conveniently drain the electroplating liquid, avoiding the problem of liquid accumulation on the contact surface between the battery cell 60 and the electroplating liquid, thereby improving the electroplating quality.
[0095] See also Figures 4 to 8 , the following provides an isolation tank 50 with an isolation plate and an electrolytic cell, but the structure of the isolation tank 50 is not limited thereto.
[0096] Specifically, the isolation tank 50 includes a frame, an isolation plate and a corrugated adjustment plate, wherein the frame includes a bottom plate 101, a first side plate 112, a second side plate 122, a first end plate 113 and a second end plate 123 connected to each other, and the bottom plate 101, the first side plate 112, the second side plate 122, the first end plate 113 and the second end plate 123 connected to each other constitute a cavity with an opening, and the first end plate 113 and the second end plate 123 are both provided with roller mounting positions, such as Figure 7The first roller mounting position 107 is located on the first end plate 113, and the first end plate 113 is provided with a first plating solution outlet 114, a second plating solution outlet 124 and an electrolyte inlet 105 adjacent to the bottom plate 101, and an electrolyte outlet 106 located above the electrolyte inlet 105; the isolation plate is arranged in the cavity, including a first isolation plate 201 and a second isolation plate 202, wherein the first isolation plate 201 is connected to the first end plate 113, the second end plate 123 and the bottom plate 101, and similarly, the second isolation plate 202 is also connected to the first end plate 113, the second end plate 123 and the bottom plate 101, and the cavity is divided into two parts including the separated parts by the first isolation plate 201 and the second isolation plate 202. The electrolytic cell 403 and the first electroplating solution reflux groove 401 and the second electroplating solution reflux groove 402 located on both sides of the electrolytic cell 403, and the first electroplating solution reflux groove 401 is connected to the first electroplating solution outlet 114, the second electroplating solution reflux groove 402 is connected to the second electroplating solution outlet 124, and the electrolytic cell 403 is connected to both the electrolyte inlet 105 and the electrolyte outlet 106; the top surface of the corrugated adjustment plate is corrugated, including a first corrugated adjustment plate 301 connected to the first side plate 112 and a second corrugated adjustment plate 302 connected to the second side plate 122, and the top surface of the first corrugated adjustment plate 301 is convexly arranged on the top surface of the first side plate 112, and the top surface of the second corrugated adjustment plate 302 is convexly arranged on the top surface of the second side plate 122.
[0097] Among them, see Figure 3 and Figure 4 Since the isolation groove 50 is provided with the first plating liquid reflux groove 401 and the second plating liquid reflux groove 402, one of the conductive brush comb teeth 42 in the conductive brush group can correspond to the first plating liquid reflux groove 401, and the other conductive brush comb tooth portion 42 can correspond to the second plating liquid reflux groove 402, and the ends of the conductive brush comb tooth portions 42 are respectively extended into the corresponding plating liquid reflux grooves, and there is a spacing between each conductive brush comb tooth portion 42 and the corresponding corrugated adjustment plate in the lateral direction, so as to effectively avoid the contact between the conductive brush comb tooth portion 42 and the plating liquid, thereby achieving an isolation effect.
[0098] See also Figure 3 , Figure 7 and Figure 8Since the isolation groove 50 is provided with the roller mounting position and the corresponding electrolytic cell 403, the roller 800 installed on the roller mounting position can be a cathode roller as needed, such as being electrically connected through a cable 801 to achieve roller-type horizontal electroplating. At this time, the conductive brush 40 can be adjusted away from the battery cell 60 or contact the back of the battery cell 60 through the adjustment of the adjustment base 10 as an auxiliary pressing component. The setting of the isolation groove 50 can provide a very ideal isolation device for the plating solution and the electrolyte, which is suitable for horizontal electroplating equipment for electroplating such as photovoltaic cells; and when the conductive brush 40 is used as a cathode conductive brush, the roller 800 installed on the roller mounting position can be used as a transmission roller to achieve electroplating of topcon cells, etc., that is, a conductive brush-type horizontal electroplating equipment is provided. Therefore, the horizontal electroplating device in this embodiment can be flexibly applied in combination with product requirements.
[0099] See also Figure 7 In this embodiment, the electrolyte inlet 105, the electrolyte outlet 106, the first plating solution outlet 114 and the second plating solution outlet 124 are all arranged on the first end plate 113, but it is not limited to this arrangement.

[0100] The number and shape of the electrolyte inlet 105 , the electrolyte outlet 106 , the first plating solution outlet 114 and the second plating solution outlet 124 can be set as required and are not limited here.
[0101] Since both the plating solution and the electrolyte are strong acid solutions, the materials of the bottom plate 101, the first side plate 112, the second side plate 122, the first end plate 113 and the second end plate 123 constituting the frame in this embodiment are preferably corrosion-resistant plastic materials, and the connection method can be selected such as welding to ensure its sealing. The selection of the material, size and connection method of each component plate in the frame is not excessively restricted here.
[0102] See also Figure 4 and Figure 6Since the top surface of the first corrugated adjustment plate 301 is corrugated and protrudes from the top surface of the first side plate 112, that is, the top surface of the first corrugated adjustment plate 301 can be regarded as having a liquid guide groove, so that when electroplating is performed, the plating liquid located outside the isolation groove 50 can enter the first plating liquid reflux groove 401 through the liquid guide groove on the end surface of the first corrugated adjustment plate 301, so that the plating liquid can be conveniently drained. When the product to be electroplated is subjected to transmission electroplating, the liquid guide groove on the end surface of the first corrugated adjustment plate 301 can solve the problem of liquid accumulation on the contact surface, and can conveniently drain the plating liquid into the first plating liquid reflux groove 401, and then discharge it through the first plating liquid outlet 114, so as to increase the fluidity of the plating liquid, avoid current concentration during electroplating, avoid the phenomenon of plating layer burning, and improve the quality of electroplating. The specific morphology, size and distribution of the liquid guide groove on the top surface of the first corrugated adjustment plate 301 can be selected according to needs and are not limited here.
[0103] The installation position, structure, etc. of the second corrugated adjustment plate 302 may refer to the first corrugated adjustment plate 301 , and will not be described in detail here.
[0104] When the roller 800 is a cathode roller, during electrolysis, the electrolyte enters the electrolytic cell 403 from the electrolyte inlet 105 adjacent to the bottom plate 101 from bottom to top, and when the electrolyte rises to the required height, it can overflow from the electrolyte outlet 106 located above the electrolyte inlet 105, thereby ensuring that electrolyte for electrolytic cleaning of the cathode roller 800 is retained in the electrolytic cell 403.
[0105] The isolation groove 50 in this embodiment can conveniently drain the plating liquid through the arrangement of the first corrugated adjustment plate 301 and the second corrugated adjustment plate 302, avoid the problem of liquid accumulation on the contact surface, and improve the quality of electroplating; when the cathode roller is electrolyzed, the isolated electrolytic tank 403, the first plating liquid reflux tank 401 and the second plating liquid reflux tank 402 can avoid the phenomenon of short circuit caused by the cross-liquid between the electrolyte and the plating liquid.

[0108] Furthermore, it is preferred that the electrolyte outlets 106 are located on both sides of the electrolyte inlet channel 600, and the electrolyte channel outlets 601 are arranged at equal intervals to further improve the flow stability of the electrolyte.
[0109] The material of the electrolyte inlet channel 600 is preferably a corrosion-resistant plastic material. Regarding the morphology of the electrolyte inlet channel 600 and the morphology and distribution of the electrolyte channel outlet 601, no excessive restrictions are made here.
[0110] As an example, a reinforcing rib connected to both the side plate and the isolation plate may be provided in the electroplating solution reflux tank, and a distance may be provided between the reinforcing rib and the bottom plate 101 .
[0111] For details, see Figure 4 In this embodiment, a first reinforcing rib 501 connected to both the first side plate 112 and the first isolation plate 201 is provided in the first electroplating solution reflux groove 401, and a spacing is provided between the first reinforcing rib 501 and the bottom plate 101 to provide a flow channel for the electroplating solution, so that the probability of deformation of the first side plate 112 and the first isolation plate 201 can be effectively reduced through the first reinforcing rib 501. Similarly, a second reinforcing rib 502 connected to both the second side plate 122 and the second isolation plate 202 is provided in the second electroplating solution reflux groove 402, and a spacing is provided between the second reinforcing rib 502 and the bottom plate 101 to provide a flow channel for the electroplating solution, so that the probability of deformation of the second side plate 122 and the second isolation plate 202 can be effectively reduced through the second reinforcing rib 502. Therefore, by providing the first reinforcing rib 501 and the second reinforcing rib 502, the stability of the electroplating solution and the electrolyte can be improved to achieve high-quality electroplating and electrolysis.
[0112] The material of the first reinforcing rib 501 and the second reinforcing rib 502 may be corrosion-resistant plastic material, and there is no excessive restriction on the distribution of the first reinforcing rib 501 and the second reinforcing rib 502.

[0114] Specifically, when the corrugated adjustment plate adopts an adjustable corrugated adjustment plate that can be moved to adjust its height, the height of the corrugated adjustment plate can be conveniently adjusted according to the height of the electroplating solution to expand the scope of application and achieve high-quality electroplating.
