Description

Technical Field

[0001] This invention relates to the field of electroplating equipment technology, and more specifically to a fully automatic horizontal electroplating line. Background Technology

[0002] Currently, the mainstream manufacturing process for photovoltaic cell electrode grid lines is screen printing silver paste. However, this process is limited by its inherent principles, making it difficult to further refine the grid line size. The high cost of silver paste, accounting for over 50% of the non-silicon cost of the cell, severely hinders the photovoltaic industry's efforts to reduce costs and increase efficiency. With the promotion of high-efficiency cell technologies such as TOPCon and HJT, the industry's requirements for grid line refinement, conductivity, and mass production efficiency continue to rise, making screen printing silver paste inadequate for the industry's upgrading needs. To overcome these challenges, the industry has proposed using copper electroplating technology to replace screen printing silver paste, achieving grid line metallization. The quality of copper electroplated grid lines directly affects the conductivity and final photoelectric conversion efficiency of the cell. Existing electroplating solutions are mostly vertical, requiring the cell to be clamped using a carrier, which has several drawbacks: firstly, uneven contact between the cell and the electroplating solution leads to significant differences in coating thickness and insufficient grid line uniformity; secondly, the clamping process easily generates mechanical stress, causing microcracks and increased breakage rates in thin-film cells; and thirdly, low production efficiency and large consumption of electroplating solution.

[0003] The development of horizontal electroplating methods is currently slow, mainly due to problems such as significant edge electric field effects, poor uniformity of grid line height, and susceptibility to grid breakage, which severely affect the conductivity and reliability of solar cells. Therefore, the photovoltaic industry urgently needs a horizontal electroplating technology that can achieve refined grid line fabrication, effectively improve electroplating uniformity and stability, reduce production costs, and is suitable for industrial mass production.

[0004] Patent CN223386254U proposes a horizontal electroplating device for photovoltaic cells, introducing magnetic fluid into the conductive stage of horizontal electroplating. Through an overflow electroplating tank, height difference design, and multiple tanks connected in series, it improves the sufficient contact of the plating solution and the uniformity of the electroplated layer. However, the maintenance of the magnetic fluid and conductive rollers is difficult, the process parameters are not quantified, and the structure lacks versatility. Patent CN223548132U proposes a horizontal electroplating device that combines a conductive fixing part and a conductive contact part to form a cathode conductive brush, integrating a double-layer isolation tank with an inner and outer isolation tank. However, this device is difficult to maintain and lacks versatility. Patent CN223837614U proposes a horizontal electroplating device for solar cells, using conductive grippers and multiple conductive tapes for conductivity. It reduces chemical disturbance by designing the angle between the inclined surface and the moving direction. However, it lacks an adjustable structure; the inclined surface angle, step size, and groove spacing are all fixed values, making it unsuitable for different sized solar cells. Summary of the Invention

It should be noted that the specific embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the invention.

The control system 8 is electrically connected to the power system 3, the fixture platform assembly 6, and the liquid storage and circulation assembly 7, respectively, for unified coordination of the operation of each component.

[0033] like Figure 1 and Figure 2 As shown, the functional tank assembly 1 includes several functional tanks arranged sequentially and fixedly connected, and each tank has interconnected tracks 10 on its inner side. In this embodiment, the functional tanks in the functional tank assembly 1 include an upper tank 11, a pretreatment tank 12, a pre-washing tank 13, an electroplating tank 14, a post-washing tank 15, and an lower tank 16 connected sequentially; the tracks 10 on the inner side of each treatment tank are undulating, that is, the tracks 10 undulate in a wave-like or sawtooth shape along the direction of the battery cell's movement in each tank, which is used to realize the up and down movement of the electroplating fixture assembly 5 in each functional tank, so as to ensure that the battery cell and the treatment liquid in each functional tank are in full and uniform contact.

[0034] like Figure 1 and Figure 3As shown, the support frame assembly 2 is installed on the foundation ground and is used to support and fix the entire equipment.

[0035] like Figure 1 and Figure 4 As shown, the power system 3 is installed on both sides of the functional slot assembly 1 and fixed on the sprocket support frame 22 of the support frame assembly 2. In this embodiment, the power system 3 includes a speed-regulating motor 31, a drive wheel assembly 32, a driven wheel assembly 33, a chain 34, and chain sliders 35. The speed-regulating motor 31 is installed on the upper front end area of ​​the functional slot assembly 1 to provide power, and its speed is adjusted by the control system 8 according to process requirements. The drive wheel assembly 32 is installed on the output shafts on both sides of the speed-regulating motor 31 to transmit power. Each driven wheel assembly 33 is distributed on the sprocket support frame 22 on both sides of the functional slot assembly 1. The chain 34 surrounds and connects the drive wheel assembly 32 and all driven wheel assemblies 33 to form a closed loop transmission circuit. The chain sliders 35 are evenly distributed on the chain 34, and each chain slider 35 moves synchronously with the chain 34 to push the electroplating fixture assembly 5 forward.

[0036] like Figure 1 and Figure 5 As shown, the anode assembly 4 is connected to the support frame assembly 2 and installed in the electroplating tank 14. In this embodiment, the anode assembly 4 includes an insoluble anode plate 41, an upper anode adjustment frame 42, a lower anode adjustment frame 43, an anode conductive sheet 44, and an anode support 45. The insoluble anode plate 41 is adjustablely connected to the upper anode adjustment frame 42 (e.g., via a long-hole bolt or a screw adjustment mechanism), allowing for vertical adjustment of the height of the insoluble anode plate 41. The lower anode adjustment frame 43 is installed below the insoluble anode plate 41 and fixed to the inner wall of the electroplating tank 14 of the functional tank assembly 1, providing lower support and auxiliary positioning. The anode conductive sheet 44 is installed on both sides of the lower anode adjustment frame 43, introducing the positive electrode of the power supply into the insoluble anode plate 41. The anode support 45 is fixedly connected to the upper anode adjustment frame 42 and is bolted to the upper edge of the electroplating tank 14 or the support frame assembly 2, thus fixing the overall position of the insoluble anode plate 41.

[0037] like Figure 1 and Figure 6 As shown, the electroplating fixture assembly 5 is slidably disposed within the track 10 of the functional slot assembly 1, and is driven to move along the track 10 by the chain slider 35 of the power system 3. In this embodiment, the electroplating fixture assembly 5 includes an electroplating fixture base plate 51, an electroplating fixture cover plate 52, a swing linkage 54, a connecting rod roller 55, and a fixture roller 56; the electroplating fixture cover plate 52 is mounted on the electroplating fixture base plate 51 and is used to fix the battery cell 53 and act as a cathode conductor to achieve conductive contact with the battery cell 53; the electroplating fixture base plate 51 and the electroplating fixture cover plate 52 are opened and closed by the corner cylinder 62 of the fixture platform assembly 6. The swing linkage 54 is fixed on both sides of the electroplating fixture base plate 51, and the connecting rod roller 55 is disposed at the end of the swing linkage 54 for abutting against the chain slider 35. The clamping rollers 56 are mounted on both sides of the electroplating fixture base plate 51 and are slidably disposed within the track 10 of the functional slot assembly 1. The chain slider 35 of the power system 3 abuts against the connecting rod roller 55 to push the electroplating fixture assembly 5 to move along the track 10.

[0038] like Figure 1 and Figure 7 As shown, the clamping platform assembly 6 is installed at both ends of the functional slot assembly 1 (i.e., the front end of the upper slot 11 and the rear end of the lower slot 16), and is used to control the opening and closing of the electroplating clamping cover plate 52 of the electroplating clamping assembly 5 to realize the loading and unloading of the battery cell 53. In this embodiment, the clamping platform assembly 6 includes a platform base plate 61, a corner cylinder 62, a support column 63, and a platform cover plate 64. The platform base plate 61 is fixed in the end slot of the functional slot assembly 1. The corner cylinder 62 and the support column 63 are installed on the platform base plate 61. The platform cover plate 64 is fixedly connected to the support column 63. A through hole is provided on the platform cover plate 64. The cylinder rod of the corner cylinder 62 passes through the through hole to lift or release the electroplating clamping cover plate 52, thereby controlling the opening and closing of the electroplating clamping assembly 5. The number of corner cylinders 62 can be set in multiples (e.g., 2 to 6) according to the size of the electroplating fixture cover plate 52 and the clamping requirements, so as to ensure smooth opening and closing action and uniform clamping force.

[0039] like Figure 1 and Figure 8As shown, the liquid storage and circulation assembly 7 is disposed on one side of the functional tank assembly 1, and is used to supply liquid and filter solutions for each functional tank. In this embodiment, the liquid storage and circulation assembly 7 includes a pretreatment liquid storage tank 71, a pretreatment filter 72, a pure water filter 73, a water washing liquid storage tank 74, a copper plating filter 75, and a copper plating liquid storage tank 76. These components are arranged sequentially on the side of the functional tank assembly 1 and connected to the corresponding functional tanks via pipes. Specifically, the pretreatment liquid storage tank 71 is connected to the pretreatment tank 12 via the pretreatment filter 72; the pure water filter 73 is connected to the water washing liquid storage tank 74 and then connected to the pre-wash tank 13 and the post-wash tank 15; and the copper plating liquid storage tank 76 is connected to the electroplating tank 14 via the copper plating filter 75, thus achieving circulating supply and real-time filtration of solutions in each tank. Pumps and valves (not shown) are also installed on the pipes between each liquid storage tank and filter, which are uniformly controlled by the control system 8 to achieve precise adjustment of the liquid supply flow rate and filtration rate.

[0040] The following is combined with Figures 1 to 8 The specific working process of this embodiment will be described in detail below: Step 1) Loading: The control system 8 starts the air pump (not shown), and the cylinder rod of the corner cylinder 62 in the fixture platform assembly 6 extends, lifting the electroplating fixture cover plate 52 upward, so that the electroplating fixture assembly 5 is in the open state. At the same time, the control system 8 controls the loading and unloading device (not shown) to grab the battery cell 53 to be electroplated and accurately place the battery cell 53 on the electroplating fixture base plate 51; then the control system 8 controls the air pump to release air, the cylinder rod of the corner cylinder 62 falls back, and the electroplating fixture cover plate 52 falls under its own weight or spring return force, pressing the battery cell 53 smoothly onto the electroplating fixture base plate 51. At the same time, the electroplating fixture cover plate 52 and the grid area on the surface of the battery cell 53 form a cathode conductive contact, completing the fixation and conductive connection of the battery cell 53.

[0041] Step 2) Electroplating Transfer: The control system 8 controls the power supply to be turned on, and the speed-regulating motor 31 of the power system 3 starts to operate at the set speed, driving the drive wheel assembly 32 to rotate, which in turn drives the chain 34 and all driven wheel assemblies 33 to rotate synchronously. The chain sliders 35 evenly distributed on the chain 34 move with the chain 34. During the forward movement of the chain sliders 35 located at the upper plate station, they abut against the connecting rod rollers 55 in the electroplating fixture assembly 5 and continuously push the connecting rod rollers 55, thereby pushing the entire electroplating fixture assembly 5 forward along the track 10.

[0042] Step 3) In-tank treatment: Under the push of the chain slider 35, the clamping rollers 56 of the electroplating fixture assembly 5 slide along the tracks 10 inside each tank of the functional tank assembly 1. Since the tracks 10 inside each treatment tank are undulating, during the sliding process, the clamping rollers 56 drive the entire electroplating fixture assembly 5 to rise or fall vertically. The swing linkage 54 swings with the undulation of the tracks 10, ultimately driving the battery cell 53 to move up and down reciprocally with the undulation of the tracks 10. The battery cell 53 moves horizontally forward while moving up and down, passing through the upper tank 11, pretreatment tank 12, pre-washing tank 13, electroplating tank 14, and post-washing tank 15 in sequence, completing surface pretreatment (such as degreasing, micro-etching, etc.), pure water cleaning, copper electroplating, and pure water cleaning processes respectively. Inside the electroplating tank 14, an electric field is formed between the insoluble anode plate 41 of the anode assembly 4 and the solar cell 53, which serves as the cathode, in the electroplating solution. Under the current density set by the control system 8, copper plating is completed on the grid lines on the surface of the solar cell 53. Since the upper anode adjustment frame 42 and the lower anode adjustment frame 43 are located above and below the solar cell 53, respectively, and are independently adjustable, electroplating with different current densities on the front and back sides of the solar cell 53 can be achieved.

[0043] Step 4) Unloading: The electroplating fixture assembly 5 is continued to be pushed by the chain slider 35. When it moves to the unloading slot 16, the control system 8 controls the air pump to start again. The cylinder rod of the corner cylinder 62 in the fixture platform assembly 6 extends and lifts the electroplating fixture cover plate 52. At the same time, the control system 8 controls the unloading device (not shown) to grab the electroplated battery cell 53 and remove it from the electroplating fixture base plate 51, placing it on the unloading conveyor belt for subsequent processing.

[0044] Throughout the entire operation, the liquid storage and circulation assembly 7 is installed on both sides or one side of the functional tank assembly 1. The pretreatment liquid storage tank 71, pretreatment filter 72, pure water filter 73, water washing liquid storage tank 74, copper plating filter 75, and copper plating liquid storage tank 76 operate continuously in a preset sequence and flow rate, continuously supplying liquid to each functional tank and circulating and filtering the solution through pipelines and pumps, ensuring that the liquid level, concentration, and cleanliness of the treated liquid in each tank are maintained within the process requirements. The control system 8 monitors parameters such as liquid level, temperature, and pH value of each tank in real time, and automatically adjusts the liquid supply rate of the liquid storage and circulation assembly 7 and the transmission speed of the power system 3 based on the monitoring results, ensuring the stability and consistency of the entire process.

[0045] In another embodiment, depending on the size of the battery cell 53 to be electroplated (e.g., 182×91mm, 210×105mm, or 182×105mm, etc.), the corresponding size of the electroplating fixture base plate 51 and electroplating fixture cover plate 52 are selected and replaced to match the shape of the battery cell 53. Simultaneously, the operator adjusts the positions of the upper anode adjustment frame 42 and the lower anode adjustment frame 43 to optimize the spacing and electric field distribution between the insoluble anode plate 41 and the battery cell 53, ensuring that battery cells of different sizes can obtain a uniform plating thickness. The width and undulation of the track 10 of the functional groove assembly 1 can be pre-set to a universal track compatible with the aforementioned multiple sizes, or a track module of the corresponding size can be replaced as needed to adapt to the passage requirements of battery cells of different sizes. The number of corner cylinders 62 can be set to multiple (e.g., 2, 4, or 6) according to the actual size and weight of the electroplating fixture cover plate 52 to ensure uniform clamping and smooth opening and closing of large-sized battery cells.

[0046] In another embodiment, based on mass production capacity requirements, multiple sets of electroplating fixture assemblies 5 are evenly distributed on the chain 34. For example, 1 to 12 battery cells can be placed at a time, or 1 to 100 battery cells can be placed at a time by lengthening and widening equipment (increasing the closed loop length of the chain 34, increasing the volume and length of the functional slots). Under the push of the chain slider 35, each set of electroplating fixture assemblies 5 moves synchronously along the track 10 at the same speed and spacing, and completes the processing of each slot in sequence, realizing large-scale synchronous continuous production and greatly improving production efficiency.

[0047] In another embodiment, the speed-regulating motor 31 of the power system 3 can be replaced by a servo motor instead of a conventional speed-regulating motor, and an encoder can be used to achieve closed-loop speed control, so as to precisely control the movement speed and acceleration / deceleration curve of the chain 34 and adapt to the different requirements of transmission speed in different processes. At the same time, the chain 34 can be replaced by a synchronous belt, and the chain slider 35 can be replaced by a synchronous belt lever, which can also realize intermittent or continuous pushing of the electroplating fixture assembly 5.

[0048] The above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also fall within the scope of the present invention, and the patent protection scope of the present invention should be defined by the claims.
