Description

Technical Field

[0001] This utility model belongs to the field of electroplating technology, specifically relating to an anode mechanism for electroplating equipment and electroplating equipment. Background Technology

[0002] Photovoltaic cells convert solar energy into electrical energy through grid lines on their surface. The quality of the grid lines' manufacturing process determines the performance of the photovoltaic cell. To improve the quality of the grid line manufacturing process, the corresponding process equipment should be optimized. For example, the applicant's previous patent CN219603745U proposed an anode mechanism for a grid line electroplating tank-type equipment. By setting up mounting units that cooperate with the anode sheets, the flatness of the anode sheet installation is improved, thereby reducing the anode sheet breakage rate and improving durability. Utility Model Content

[0003] This invention aims to further improve the structural precision of the anode mechanism in grid-type electroplating tank equipment.

[0004] This utility model is achieved through the following technical solution:

[0005] An anode mechanism for an electroplating device includes an anode support, a fixing component, and an anode plate, wherein the anode plate is connected to the anode support via the fixing component, characterized in that:

[0006] The anode plate is provided with assembly holes;

[0007] The fixing component includes:

[0008] A mounting base is connected to the anode support;

[0009] The clamping structure comprises multiple sets of clamping structures spaced apart; each set of clamping structures includes a pair of limiting rods fixedly connected to the fixing base, the spacing between the pair of limiting rods being adapted to the thickness of the anode sheet, and the anode sheet being engaged in the clamping structure.

[0010] An assembly shaft, wherein the cross-sectional profile of the assembly shaft is adapted to the inner profile of the assembly hole;

[0011] Multiple anode plates are connected in series on the assembly shaft through the assembly holes.

[0012] This technical solution employs a limiting rod and an assembly shaft to dual-correct the alignment accuracy of the anode plates. During the assembly of the anode mechanism, multiple anode plates need to be welded to a fixed assembly to form a single unit. The limiting rod in the clamping structure corrects the tilt of individual anode plates, while the tight engagement of the assembly shaft with the assembly holes helps correct the parallelism between multiple anode plates and prevents positional shifts during welding. During the operation of the electroplating equipment, the presence of the assembly shaft strengthens the overall integrity of the anode structure and resists localized deformation caused by repeated use.

[0013] Preferably, the fixing component further includes an assembly positioning member, the length of which is adapted to the spacing between adjacent clamping structures; the assembly positioning member is connected to the assembly shaft and the connection position is between adjacent assembly holes.

[0014] Preferably, the assembly positioning component is sleeved on the assembly shaft, and the internal cross-sectional profile of the assembly positioning component is adapted to the cross-sectional profile of the assembly shaft.

[0015] Preferably, assembly fasteners are provided at both ends of the assembly shaft, and the assembly fasteners cooperate with the assembly positioning components to form a control structure for the spacing of the anode plates.

[0016] By using assembly positioning elements to space adjacent assembly holes and forming a limiting structure with the assembly fixing elements, the spacing between the anode plates can be further controlled after correcting the parallelism. When the assembly positioning elements are tightly fitted with the assembly shaft, it can increase the friction between the assembly positioning elements and the assembly shaft to prevent slippage, and also increase the strength of the assembly shaft.

[0017] Preferably, a positioning rod is provided between adjacent limiting rods belonging to adjacent clamping structures, and the positioning rod is a rigid support member.

[0018] The positioning rods are used to maintain the spacing between the limiting rods and prevent the clamping structure itself from deforming during assembly or equipment operation, which would reduce the alignment accuracy of the anode sheets.

[0019] Preferably, the fixing base is provided with two rows of clamping structures, which are symmetrically distributed on the left and right sides along the extension direction of the fixing base.

[0020] Preferably, the anode sheet includes a positioning area, an assembly area, and a coating area; the contact position between the clamping structure and the anode sheet is located within the positioning area.

[0021] Preferably, the assembly hole is located within the assembly area; the assembly area is symmetrically distributed on both sides of the coating area on the anode sheet.

[0022] The coating area is the functional area of ​​the anode structure. Dividing the functional area ensures that the coating has a regular shape and improves the uniformity of electroplating. The assembly area and positioning area, which are symmetrically arranged on both sides, are distributed on the anode plate to form a multi-point force, enhancing the control of the structural precision of the anode plate.

[0023] Preferably, the fixing seat has multiple fixing holes, and the anode bracket has multiple mounting holes; the spacing between the fixing holes is adapted to the spacing between the mounting holes.

[0024] This utility model also includes an electroplating device, characterized in that it includes the anode mechanism of the electroplating device described in any one of the above claims.

[0025] This invention proposes an anode mechanism and electroplating equipment for a grid-type electroplating tank with higher anode sheet arrangement accuracy. In addition to the positioning area, an assembly area is added to the anode sheet. The positioning area is fixed by two sets of clamping structures, and the assembly area is fixed by multiple assembly shafts. Each anode sheet has at least four position correction points, greatly improving the structural accuracy of the anode mechanism. During the assembly of the anode mechanism, welding is required at the connection between the limiting rod and the anode sheet. To prevent or counteract deformation that may occur during the welding process, this invention enhances the overall structural strength through assembly shafts, stabilizes the flatness and arrangement spacing of the anode sheets through assembly positioning and fixing components, and stabilizes the spacing of the clamping structures through positioning rods.

[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Those skilled in the art will be able to implement the present invention based on these descriptions. Furthermore, the embodiments of the present invention described below are generally only a part of the embodiments of the present invention, and not all of the embodiments. Therefore, all other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.

[0036] Example 1

[0037] The first step in designing this device is to design the shape of the anode plate 3.

[0038] Please see Figure 1 and Figure 3 The upper part of the anode plate 3 is the coating area 330, covered with a precious metal coating. The coating shape of the coating area 330 is a standard rectangle to improve electroplating uniformity. Below the coating area 330 is the positioning area 310, which serves as the clamping and welding position for the anode plate 3. An assembly area 320 is located on each of the left and right sides of the coating area 330, with assembly holes 321 provided for auxiliary fixing positions of the anode plate 3. The assembly areas 320 and the coating area 330 form a triangular distribution, giving the anode plate 3 multiple force points for attitude control.

[0039] The next step in this design is to examine the connection method between the anode plate 3 and the fixing component 2.

[0040] Please see Figure 2 and Figure 5 The fixing component 2 includes a fixing base 210 and clamping structures. The fixing base 210 is a flat plate structure, and its extension direction is consistent with the extension direction of the anode support 1. Each clamping structure includes two pairs of limiting rods 220. The spacing between these two limiting rods 220 is adapted to the thickness of a single anode sheet 3, so that an anode sheet 3 can be precisely engaged within them. The limiting rods 220 are perpendicular to the upper surface of the fixing base 210 and are fixedly connected to the fixing base 210, so that the anode sheet 3 also has a structural posture perpendicular to the fixing base. The fixing base 210 is provided with two rows of clamping structures, which are symmetrically distributed on the left and right sides along the extension direction of the fixing base 210, that is, each anode sheet 3 is fixed by two sets of clamping structures symmetrically arranged on the left and right sides.

[0041] Please see Figure 4 and Figure 5The fixing assembly 2 also includes an assembly shaft 230, an assembly shaft positioning member 240, and an assembly shaft fixing member 250. The assembly hole 231 and the assembly shaft positioning member 240 both have inner contours adapted to the outer contour of the cross-section of the assembly shaft 230, allowing them to be tightly fitted onto the assembly shaft 230. The assembly holes 231 and the assembly positioning members 240 are arranged alternately on the assembly shaft 230, ensuring equal spacing between the assembly areas 320 of the multiple sets of anode plates 3. Because the length of the assembly shaft positioning member 240 is adapted to the spacing of the clamping structure, the positioning areas 310 of the multiple sets of anode plates 3 also have equal spacing, allowing the anode plates 3 to remain parallel as a whole. Assembly fixing members 250 are provided at both ends of the assembly shaft 230 to define the positions of the assembly holes 321 and the assembly positioning members 240 on the assembly shaft 230. In some embodiments, the assembly fastener 250 and the assembly shaft 230 are fixedly connected without adjustment. In this case, the assembly fastener 250 provides structural restraint for the assembly hole 321 and the assembly positioning member 240 through its position. In some embodiments, the two ends of the assembly shaft 230 are threaded. In this case, the assembly fastener 250 is a nut fitted onto the assembly shaft 230. The nuts at both ends are tightened towards each other, which can apply a preload to the anode plate 3 and the assembly positioning member 240 sandwiched between them, preventing shaking or deformation during the operation of the welding and electroplating equipment.

[0042] To improve the neatness of the assembled anode sheet 3, the shape of the fixing component 2 was further optimized.

[0043] Please see Figure 5 Two limiting rods 220 belonging to adjacent clamping structures are connected by a rigid positioning rod 221 to control the spacing between the limiting rods 220. At this time, the two limiting rods 220 and the positioning rod 221 combine to form a U-shaped positioning element, and the clamping structure is composed of adjacent U-shaped positioning elements. During the component processing, the U-shaped positioning element can be produced as a single part, improving installation uniformity.

[0044] The fixing component 2 of this device is connected to the anode support 1 using fasteners.

[0045] Please see Figure 4 and Figure 5 The anode bracket 1 is made of titanium-clad copper and has multiple sets of mounting holes 110 on its surface. The mounting base 210 has multiple sets of mounting holes 211. The spacing of the mounting holes 110 and the mounting holes 211 are matched to ensure alignment. Fasteners pass through both to lock the bracket in place. When the anode bracket 1 is long, the mounting base 210 will support multiple anode plates 3; to avoid accumulated errors and deformation during assembly, the mounting base 210 needs to be disassembled into multiple sections and installed onto the anode bracket 1 separately. This detachable connection method allows one anode bracket 1 to be matched with multiple mounting bases 210.

[0046] The assembly steps for this device are as follows:

[0047] 1. The assembly shaft 230 passes through the assembly hole 321 of a single anode plate 3 to be assembled and then a mounting positioning piece 240 is sleeved on it. This sequence is repeated so that adjacent anode plates 3 are separated by a mounting positioning piece 240.

[0048] 2. Fit an assembly fastener 250 onto each end of the assembly shaft 230 and lock it in place, so that the anode sheet 3 on the assembly shaft 230 and the assembly positioning part 240 are in close contact, thus obtaining a stable anode sheet assembly.

[0049] 3. Position the anode plate assembly onto the fixing base 210, so that the positioning area 310 of the anode plate 3 is inserted between the adjacent U-shaped positioning parts;

[0050] 4. Weld the connection between the positioning area 310 and the U-shaped positioning component to obtain a stable anode assembly;

[0051] 5. Align the fixing seat hole 211 and the mounting hole 210, place the anode plate assembly on the anode bracket 1, and use multiple fasteners to pass through the fixing seat hole 211 and the mounting hole 210 and tighten them; use a torque wrench when tightening to ensure that each fastener is subjected to the same force and that the conductivity is uniform.

[0052] 6. Obtain the anode mechanism of the electroplating equipment.
