Description

Technical Field

[0001] The present invention relates to the technical field of electroplating process equipment, and more specifically, to an electroplating equipment for processing battery cells. Background Art

[0002] The current mainstream process for manufacturing metal grid lines on solar cells is to use screen printing to print conductive silver paste on solar cells and then sinter them, but the cost of conductive silver paste is relatively high. In order to reduce process costs, the method of making metal grid lines using the lower-cost copper plating process has been industrialized on a large scale.

[0003] The cell electroplating process includes multiple processing techniques, such as pre-treatment, electroplating and post-treatment; pre-treatment includes cleaning, degreasing and pickling; post-treatment includes water washing, mask removal and drying.

[0004] The processing time required for the electroplating process is often greater than the processing time of the pre-treatment process, resulting in a linear electroplating line. The battery cells after pre-treatment need to stop the line and wait for the electroplating of the previous batch of battery cells to be completed, which results in slow electroplating and low electroplating efficiency.

[0005] Moreover, if the coating thickness is changed during the electroplating process, the corresponding electroplating time needs to be increased, which further aggravates the problem of mismatch between the pre-treatment process time and the electroplating time, and the electroplating process cannot be flexibly adapted. In view of this, we propose an electroplating device for battery cell processing. Summary of the invention

[0006] 1. Technical issues to be solved

[0007] The purpose of the present invention is to provide an electroplating equipment for processing battery cells, which solves the technical problem of mismatch between the pre-treatment process time and the electroplating process time of the battery cells in the prior art, and achieves the technical effect of flexible matching of the electroplating process and the pre-treatment process time.

[0008] 2. Technical solution

[0009] The embodiment of the present invention provides an electroplating device for processing a battery cell, comprising a plurality of electroplating tanks, a plurality of pre-treatment tanks and a plurality of post-treatment tanks, wherein the plurality of electroplating tanks are arranged side by side;

[0010] The pre-treatment tank and the post-treatment tank are both connected to the electroplating tank via a transition tank;

[0011] The electroplating tank, the plurality of pre-treatment tanks and the plurality of post-treatment tanks are all equipped with a first conveying line for conveying workpieces;

[0012] A plurality of electroplating tanks, a plurality of pre-treatment tanks, a plurality of post-treatment tanks and two groups of transition tanks are all provided with feeding holes of equal height and interconnected with each other;

[0013] Two groups of rotating components and adjusting components are arranged in the transition tank, the center distance between the two groups of rotating components is equal to the center distance between the feeding holes on the two adjacent groups of electroplating tanks, and the second conveying line and a plurality of third conveying lines are installed on the rotating components for conveying workpieces;

[0014] The rotating assembly is used to switch the conveying positions of the second conveying line and a plurality of third conveying lines, and the adjusting assembly is used to switch the positions of the two groups of rotating assemblies.

[0015] By adopting the above technical solution, the equipment can perform different modes of electrode sheet feeding according to the different working numbers of plating tanks, which improves the flexibility of electrode sheet transportation, effectively solves the problem of time asynchrony between the pre-treatment process and the electroplating process, and improves the efficiency of electroplating.

[0016] As an optional solution of the technical solution of the document of the present invention, the width of several pre-treatment tanks and several post-treatment tanks is not greater than the width of the electroplating tank, and the width of the transition tank is not less than the sum of the widths of several groups of electroplating tanks.

[0017] As an optional solution of the technical solution of the document of the present invention, the conveying heights of the first conveying lines, the second conveying lines and the third conveying lines and the opening heights of the feeding holes are all the same.

[0018] As an optional solution of the technical solution of the document of the present invention, there is a set angle between the conveying direction of the third conveying line and the conveying direction of the second conveying line.

[0019] As an optional solution of the technical solution of the present invention, the rotating assembly includes a driving motor and a support plate, the output shaft of the driving motor is fixedly mounted with a first gear, the support plate is fixedly mounted with a support shaft, the support shaft is fixedly mounted with a second gear, the first gear is meshed with the second gear for transmission, the second conveyor line and several third conveyor lines are fixedly mounted on the corresponding support plates, and the support shaft is rotatably connected with the adjusting assembly.

[0020] By adopting the above technical solution, the output shaft of the driving motor drives the first gear to rotate, and drives the support shaft and the support plate to rotate through meshing transmission with the second gear, thereby realizing the switching of the conveying direction and position of the second conveyor line and the third conveyor line.

[0021] As an optional solution of the technical solution of the document of the present invention, it also includes a photoelectric sensor;

[0022] The photoelectric sensor includes a plurality of transmitters and a plurality of receivers. There is at least one receiver directly below each second conveying line and the third conveying line, and the plurality of receivers are distributed in an array. There is at least one transmitter at both ends of each electroplating tank, and the transmitter is fixedly mounted on the transition tank.

[0023] The transmitter is located directly above the receiver that the electrode sheet first passes when being transported.

[0024] By adopting the above technical solution, when the electrode sheet is being transported, when the radio and television signal of the corresponding receiver is interrupted, it means that the electrode sheet is transported to the set position and stops being transported, thereby achieving the electrode sheet transport positioning effect.

[0025] As an optional solution of the technical solution of the document of the present invention, the adjustment component includes a support frame and a support block, the support frame is fixedly installed in the transition groove, the support block is slidably connected to the support frame, the drive motor is fixedly installed on the support block, the support shaft is rotatably connected to the support block, an electric slide is fixedly installed on the support frame, and the support block is fixedly connected to the output end of the electric slide.

[0026] By adopting the above technical scheme, a variety of working modes are provided according to the electroplating tanks with different working numbers: when a single electroplating tank is working, the support plate rotates to adjust the position of the second conveyor line to be parallel to the processing direction of the electroplating process, and the electrode sheet sent out from the pre-treatment tank is directly conveyed to the first conveyor line in the electroplating tank through the second conveyor line. After the electrode sheet is conveyed to the set position, the cathode rod contacts the two sides of the electrode sheet, and the cathode rod and the anode block are energized, thereby realizing the electroplating process. During the electroplating process, the electrode sheet does not move, thereby ensuring the stability and quality of the electroplating.

[0027] When two sets of electroplating tanks are working, according to the principle of single electroplating tank operation, a certain number of electrode sheets are transported into the electroplating tank on the electroplating process straight line for electroplating. When the electrode sheets are transported into the electroplating tank on the non-straight line, the photoelectric sensor needs to be positioned. When the electrode sheets are transmitted to the second conveyor line or the third conveyor line, the induction of the photoelectric sensor disappears, and the transportation stops. The output shaft of the driving motor drives the first gear to rotate, and drives the support shaft and the support plate to rotate through the meshing transmission with the second gear, so as to realize the switching of the conveying direction and position of the second conveyor line and the third conveyor line. The second conveyor line or the third conveyor line in the conveying position continues to receive the electrode sheets, and at the same time, the last received electrode sheet is transported to the second conveyor line or the third conveyor line on another support plate. During the next rotation, the second conveyor line or the third conveyor line transports the electrode sheets to the first conveyor line in the electroplating tank on the non-process straight line, thereby realizing the conveying operation of the two sets of electroplating tanks. The conveying of the first conveyor line is synchronized with the conveying speed of the second conveyor line and the third conveyor line, so as to ensure that a number of electrode sheets can be accurately transported to the set position, and reduce the contact difficulty of the subsequent cathode rod;

[0028] When there are more than two groups of working electroplating tanks, first, according to the working mode of a single electroplating tank, the electrode sheets are transported into the electroplating tank on the electroplating process line. After the transportation is completed, the second conveyor line and the third conveyor line on the support plate start the storage mode and use the photoelectric sensor for positioning. Every time an electrode sheet is stored in the second conveyor line and the third conveyor line, the support plate rotates the set angle and switches to the storage position of the second conveyor line or the third conveyor line for the next storage until the second conveyor line and the third conveyor line on a support plate are full of storage. The output end of the electric slide drives the two groups of rotating components to switch positions and positions when switching through the photoelectric sensor, that is, the photoelectric sensing disappears and the photoelectric sensing is triggered again. The second conveyor line and the third conveyor line full of electrode sheets are switched to feed the electroplating tank on the side. At the same time, the second conveyor line and the third conveyor line on another group of empty support plates store materials to realize the feeding process of multiple electroplating tanks.

[0029] The setting of the photoelectric sensor can realize positioning in multiple modes and at different working times, including storage positioning during electrode sheet transportation, positioning of the rotation angle when the support plate rotates, and positioning of the moving position when the two sets of rotating components switch positions, thereby improving the reliability and stability of equipment operation and electrode sheet transportation.

[0030] As an optional solution of the technical solution of the present invention, it also includes several groups of blocking components, several pump bodies, several liquid level sensors and liquid storage tanks, each electroplating tank is connected to the liquid storage tank through the corresponding pump body, and each electroplating tank is provided with a liquid level sensor for detecting the liquid level change of the corresponding electroplating tank;

[0031] The blocking component is installed at the feeding hole of the corresponding electroplating tank and is used to block the corresponding feeding hole.

[0032] As an optional solution to the technical solution of the document of the present invention, the sealing assembly includes a plurality of telescopic cylinders and a plurality of sealing plates. The telescopic cylinders are fixedly mounted on the electroplating tank, and the sealing plates are slidably connected to the electroplating tank. The sealing plates are used to seal the corresponding feeding holes on the electroplating tank.

[0033] By adopting the above technical solution, when the electrode sheet is transported to the electroplating tank, the corresponding pump body draws the plating liquid from the electroplating tank into the liquid storage tank for storage, and uses the liquid level sensor to detect the liquid level until the liquid level drops to the set height, the sealing plate rises, and the feeding hole opens. When the electrode sheet is transported into the electroplating tank, the sealing plate drops, the feeding hole is closed, and the pump body reversely feeds the plating liquid in the liquid storage tank into the electroplating tank so that the liquid level reaches the working liquid level, thereby reducing the loss of plating liquid during the transportation of the electrode sheet.

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] The cell electroplating process includes multiple processing techniques, such as pre-treatment, electroplating and post-treatment; pre-treatment includes cleaning, degreasing and pickling.

[0048] The cleaning process is to send the battery cells into the cleaning tank and use a solution to remove dirt to ensure a clean surface; the degreasing process is to degrease specific materials such as battery connectors to remove oil and impurities on the surface; the pickling process is to place the battery cells in an acidic solution for pickling to remove oxides and impurities on the surface and improve the adhesion of the coating.

[0049] The electroplating process is to place the pretreated battery cell or connecting piece into an electrolyte containing specific metal ions, using the battery cell as the cathode. The metal ions in the electrolyte are reduced to metal and deposited on the surface of the battery cell or connecting piece to form a metal layer.

[0050] Post-processing includes washing, mask removal and drying, etc., which is to reprocess the electroplated battery cells to remove the electrolyte and residues on the surface to make the coating more uniform and dense.

[0051] Reference Figure 1 and Figure 2The present embodiment discloses an electroplating device for processing battery cells, including a plurality of electroplating tanks 1, a plurality of pre-treatment tanks 10 and a plurality of post-treatment tanks 20. The plurality of electroplating tanks 1 are arranged side by side, and the side-by-side arrangement direction is perpendicular to the process flow direction. The electroplating tank 1 is used for electroplating battery cells. The plurality of pre-treatment tanks 10 are connected end to end, and the plurality of post-treatment tanks 20 are connected end to end. The pre-treatment tank 10 is used for implementing the pre-treatment process of the battery cells, and the post-treatment tank 20 is used for implementing the post-treatment process. The width of the pre-treatment tank 10 and the plurality of post-treatment tanks 20 is not greater than the width of the electroplating tank 1. The electroplating tank 1 and the pre-treatment tank 10 and the electroplating tank 1 and the post-treatment tank 20 are connected by transition tanks 2 for transition between pre-treatment, electroplating and post-treatment processes. The width of the transition tank 2 is not less than the sum of the widths of the plurality of groups of electroplating tanks 1.

[0052] The first conveyor line 3 is installed in the electroplating tank 1, the pre-treatment tank 10 and the post-treatment tank 20. The first conveyor line 3 includes a plurality of conveying rollers and a plurality of active rollers. The plurality of conveying rollers and the plurality of active rollers are rotatably arranged on the corresponding tank bodies. The plurality of active rollers are located directly below the plurality of conveying rollers and the positions correspond to each other. The plurality of active rollers are driven by gears or toothed chains and the rotation directions of the plurality of active rollers are the same. An active roller is fixedly connected to the output shaft of the servo motor, thereby realizing the conveying of the active rollers. It should be noted that the plurality of active rollers can also be powered rollers, which is convenient for the subsequent targeted conveying of the electrode sheets. For example, if the electrode sheets need to be conveyed to the set position of the electroplating tank 1, the conveying position of the electrode sheets can be tracked and located by cooperating with a visual camera, and the corresponding active rollers are controlled to rotate and convey separately according to the position of the visual camera, thereby realizing local conveying.

[0053] The conveying heights of the first conveyor lines 3 in the electroplating tank 1, the pre-treatment tank 10 and the post-treatment tank 20 are the same, ensuring that the battery panels to be electroplated can be smoothly conveyed. The first conveyor lines 3 in the electroplating tank 1, the pre-treatment tank 10 and the post-treatment tank 20 all have independent drives, so that they can operate independently in the corresponding treatment tanks; several electroplating tanks 1, the pre-treatment tank 10, the post-treatment tank 20 and the two groups of transition tanks 2 are provided with feeding holes 4 of equal height, so that two adjacent treatment tanks are connected to each other, and the height of the feeding holes 4 is the same as the conveying height of the first conveyor line 3, realizing the continuity of the treatment process.

[0054] Reference Figures 2 to 6Two groups of rotating components 5 are arranged in each group of transition grooves 2. The rotating components 5 include a driving motor 51 and a support plate 52. The center spacing of the support plates 52 of the two groups of rotating components 5 is equal to the center spacing of the feeding holes 4 on the adjacent electroplating tank 1. The output shaft of the driving motor 51 is fixedly installed with a first gear 53. The support plate 52 is circular. A support shaft 54 ​​is fixedly installed on the support plate 52. A second gear 55 is fixedly installed on the support shaft 54. The first gear 53 is meshed with the second gear 55 for transmission. A second conveyor line 6 and a plurality of third conveyor lines 7 are fixedly installed on the support plate 52. The second conveyor line 6 includes a plurality of driven rollers and a plurality of power rollers (with driving force). The plurality of power rollers are located directly below the plurality of driven rollers, and the positions correspond one to one. The only difference between the third conveyor line 7 and the second conveyor line 6 is that there is a certain angle between the conveying direction of the third conveyor line 7 and the conveying direction of the second conveyor line 6, and the conveying heights of the second conveyor line 6 and the third conveyor line 7 are equal to the conveying height of the first conveyor line 3.

[0055] The output shaft of the driving motor 51 drives the first gear 53 to rotate, and drives the support shaft 54 ​​and the support plate 52 to rotate by meshing with the second gear 55, thereby realizing the switching of the conveying direction and position of the second conveying line 6 and the third conveying line 7.

[0056] The electroplating equipment also includes a photoelectric sensor and a plurality of conductive rings 56. The conductive rings 56 are mounted on the corresponding support shafts 54. The connecting wires of the components rotating on the support plate 52 are all led out through the conductive rings 56, thereby avoiding the problem of connecting wire entanglement during rotation.

[0057] The photoelectric sensor includes a plurality of transmitters 58 and a plurality of receivers 57. There is at least one receiver 57 directly below each second conveyor line 6 and the third conveyor line 7, and the plurality of receivers 57 are arrayed and distributed on the support plate 52. The emission light of the plurality of transmitters 58 and the plurality of receivers 57 (or the emission light of the plurality of transmitters 58 and the plurality of receivers 57 after rotating a certain angle) is perpendicular to and intersects with the center line of the feed hole 4. There is at least one transmitter 58 corresponding to each end of each electroplating tank 1. The transmitter 58 is fixedly mounted on the transition tank 2. Along the processing direction of the electroplating process, the transmitter 58 is directly above the receiver 57 that the electrode sheet passes first when being conveyed. When the electrode sheet is being conveyed, when the radio and television signal of the corresponding receiver 57 is interrupted, it indicates that the electrode sheet is conveyed to the set position and stops conveying, thereby achieving the electrode sheet conveying and positioning effect.

[0058] An adjustment component 8 is installed in the transition groove 2, and the adjustment component 8 includes a support frame 81 and a support block 82. The support frame 81 is fixedly installed in the transition groove 2, and the support block 82 is slidably connected to the support frame 81 through a guide rail 83. The drive motor 51 is fixedly installed on the support block 82, and the support shaft 54 ​​is rotatably connected to the support block 82. An electric slide 84 is fixedly installed on the support frame 81, and the support block 82 is fixedly connected to the output end of the electric slide 84 through a connecting frame 85.

[0059] This embodiment has a variety of working modes according to the different working numbers of the plating tanks 1: when a single plating tank 1 is working, the support plate 52 rotates to adjust the position of the second conveyor line 6 to be parallel to the processing direction of the electroplating process, and the electrode sheet sent out from the pre-treatment tank 10 is directly conveyed to the first conveyor line 3 in the plating tank 1 through the second conveyor line 6. After the electrode sheet is conveyed to the set position, the cathode rod 11 contacts the two sides of the electrode sheet, and the cathode rod 11 and the anode block 12 are energized, thereby realizing the electroplating process. During the electroplating process, the electrode sheet does not move, thereby ensuring the stability and quality of the electroplating.

[0060] When the two sets of electroplating tanks 1 are working, according to the principle of the single electroplating tank 1 operation, a certain number of electrode sheets are transported into the electroplating tank 1 on the straight line of the electroplating process for electroplating. When the electrode sheets are transported into the electroplating tank 1 on a non-straight line, it is necessary to cooperate with the photoelectric sensor for positioning. When the electrode sheets are transmitted to the second conveyor line 6 or the third conveyor line 7, when the induction of the photoelectric sensor disappears, the conveying stops, and the output shaft of the driving motor 51 drives the first gear 53 to rotate, and drives the support shaft 54 ​​and the support plate 52 to rotate through the meshing transmission with the second gear 55, so as to realize the conveying direction and position of the second conveyor line 6 and the third conveyor line 7. Switch, the second conveyor line 6 or the third conveyor line 7 in the conveying position continues to receive the electrode sheets, and at the same time conveys the last received electrode sheet to the second conveyor line 6 or the third conveyor line 7 on another support plate 52. During the next rotation, the second conveyor line 6 or the third conveyor line 7 conveys the electrode sheet to the first conveyor line 3 in the electroplating tank 1 which is not on the process straight line, thereby realizing the conveying operation of two groups of electroplating tanks 1. The conveying of the first conveyor line 3 is synchronized with the conveying speed of the second conveyor line 6 and the third conveyor line 7, thereby ensuring that several electrode sheets can be accurately conveyed to the set position, reducing the difficulty of contacting the subsequent cathode rod 11.

[0061] When there are more than two groups of working electroplating tanks 1, first, according to the working mode of a single electroplating tank 1, the electrode sheets are transported into the electroplating tank 1 on the electroplating process straight line. After the transportation is completed, the second conveyor line 6 and the third conveyor line 7 on the support plate 52 start the storage mode and are positioned by photoelectric sensors. Each time an electrode sheet is stored in the second conveyor line 6 and the third conveyor line 7, the support plate 52 rotates a set angle and switches to the storage space of the second conveyor line 6 or the third conveyor line 7 for the next storage until the second conveyor line 6 and the third conveyor line 7 on one support plate 52 are full of storage. The output end of the electric slide 84 drives the two groups of rotating components 5 to switch positions and positions them when switching through the photoelectric sensor, that is, the photoelectric induction disappears and the photoelectric induction is triggered again. The second conveyor line 6 and the third conveyor line 7 filled with electrode sheets are switched to feed the electroplating tank 1 on the side. At the same time, the second conveyor line 6 and the third conveyor line 7 on another group of empty support plates 52 are stored to realize the feeding process of multiple electroplating tanks 1.

[0062] It should be noted that when the electrode sheet in the electroplating tank 1 is transported backward after electroplating, it is transported to the first conveying line 3 in the post-processing tank 20 using the same working principle as above, and this process will not be repeated.

[0063] The present embodiment can perform different modes of electrode sheet feeding according to different working numbers of electroplating tanks 1, thereby improving the flexibility of electrode sheet transportation, effectively solving the problem of time asynchronism between the pre-treatment process and the electroplating process, and improving the efficiency of electroplating. The setting of the photoelectric sensor can realize positioning in multiple modes and at different working times, including storage positioning during electrode sheet transportation, positioning of the rotation angle when the support plate 52 rotates, and positioning of the moving position when the two groups of rotating components 5 switch positions, thereby improving the reliability and stability of equipment operation and electrode sheet transportation.

[0064] The end of the cathode rod 11 is bent, and the staggered movement of the cathode rod 11 can be achieved through a driving component, such as a rack is fixedly connected to each cathode rod 11, and a group of third gears are set at the same time. The third gear is meshed with the two groups of racks for transmission. The third gear is driven by a servo motor, and the rotation of the third gear drives the two groups of racks to move up and down staggered, thereby realizing the opening and closing process of the end of the cathode rod 11.

[0065] Reference Figure 2 and Figure 7The electroplating equipment also includes several groups of blocking components 9, several pump bodies, several liquid level sensors and liquid storage tanks. Each electroplating tank 1 is connected to the liquid storage tank through the corresponding pump body. Each electroplating tank 1 is provided with a liquid level sensor for detecting the liquid level changes of the corresponding electroplating tank 1; the blocking components 9 include several telescopic cylinders 91 and several sealing plates 92. The telescopic cylinders 91 are fixedly installed on the electroplating tank 1, and the sealing plates 92 are slidably connected to the electroplating tank 1. The sealing plates 92 are used to block the corresponding feeding holes 4 on the electroplating tank 1 to prevent the electroplating liquid from flowing out of the feeding holes 4.

[0066] When the electrode sheet is transported to the electroplating tank 1, the corresponding pump body draws the plating liquid from the electroplating tank 1 into the liquid storage tank for storage, and uses the liquid level sensor to detect the liquid level until the liquid level drops to the set height (lower than the feeding hole 4), the sealing plate 92 rises, and the feeding hole 4 opens. When the electrode sheet is transported into the electroplating tank 1, the sealing plate 92 drops, the feeding hole 4 is closed, and the pump body reversely feeds the plating liquid in the liquid storage tank into the electroplating tank 1, so that the liquid level reaches the working liquid level (at least immerses the electrode sheet), thereby reducing the loss of plating liquid during the electrode sheet transportation process.

[0067] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
