Description

Technical Field

[0001] This invention belongs to the field of electroplating technology, and particularly relates to a copper plating tank device for circuit boards. Background Technology

[0002] Copper plating on circuit boards is a key process in printed circuit board (PCB) manufacturing used to deposit a conductive copper layer on the surface of an insulating substrate. Its core purpose is to form electrical interconnection paths (such as wires, pads, and vias) to enable signal and power transmission between multilayer boards. Typically, a fixture is used to hold the circuit board and immerse it in a tank containing an electroplating solution. After the electroplating layer is formed during the immersion period, the circuit board is removed using the fixture. However, in this method, because the fixture needs to clamp the circuit board tightly, the electroplating layer cannot be formed at the clamping point, which leads to local defects. A device is proposed to avoid the inability to form an electroplating layer in certain areas of the circuit board. Summary of the Invention

[0014] Beneficial effects This invention provides a copper plating tank device for circuit boards, which has the following advantages compared with the prior art: 1. The user removes the sealing plug and places the circuit board horizontally inside the reservoir, ensuring the board is level. Since the reservoir is not yet rotating, the circuit board is initially positioned at the upper part of the reservoir. As the circuit board descends, it begins to immerse itself in the electroplating solution, maintaining a horizontal position. Because the circuit board contains metal components, it gradually enters the magnet's attraction range during its descent, thus maintaining its horizontal position and continuing downward movement. This process ensures sufficient contact between the electrolyte and the circuit board, enhancing the electroplating effect. The user should... The transmission assembly causes the mounting base to rotate around the housing axis, continuously attracting the circuit board. As the housing rotates, the circuit board moves towards it at a constant speed until the liquid reservoir rotates. During its descent, the circuit board rotates with the liquid reservoir until it reaches the top. Once the mounting base and magnet have passed the stop bar, the magnetism can no longer affect the ferrous components on the circuit board. Because the circuit board is now horizontal, it falls uniformly into the plating solution within the liquid reservoir. This effectively avoids the problem of clamping, which prevents plating from forming at the clamping points. Furthermore, the plating solution is in motion during this process, effectively improving the uniformity of the plating layer. 2. During the counterclockwise rotation and reset of the mounting base, the arc surface of the arc block is on the trajectory of the counterclockwise rotation of the magnet. Therefore, during the counterclockwise rotation and reset of the mounting base, the magnet can come into contact with the arc block, and the arc block will begin to slide towards the liquid storage box under the action of the magnet. This will cause the two pressure blocks to apply lateral pressure to the corresponding adhesive strips, which will cause the adhesive strips to deform. At this time, the pressure blocks push the corresponding adhesive strips into the housing. Therefore, before the magnet is reset to the bottom of the liquid storage box, if the circuit board slides to the left and right side walls of the liquid storage box, the pressure blocks and adhesive strips can work together to push the circuit board away, thereby avoiding the side of the circuit board from contacting the inner wall of the liquid storage box and causing scratches, so as to avoid affecting the formation of the electroplating layer on it. 3. When connecting rod A slides and causes gear A to start rotating, gear B, which is coaxially fixed to gear A, starts to rotate synchronously. At this time, the racks B meshing on both sides of gear B start to slide synchronously, that is, the two connecting rods B start to slide towards each other, causing the two pressure blocks A to apply a lateral thrust to their corresponding rubber strips A, causing rubber strips A to deform, so that pressure blocks A can push rubber strips A into the liquid storage box, and then push the circuit board in the front and rear directions, thus avoiding contact between the circuit board and the inner wall of the liquid storage box in four directions, until the magnet separates from the arc block. At this time, under the action of the spring, the pressure blocks and pressure block A can slide back to their original positions, so as to push the circuit board again. Attached Figure Description

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0025] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0026] Please see Figure 1 , Figure 3 , Figure 4 as well as Figure 5 According to one embodiment of the present invention, a copper plating tank device for circuit boards includes a liquid storage box 101, which is vertically disposed within a housing 201 and rotatably connected to the housing 201. A magnet 202 is horizontally disposed on the lower surface of the liquid storage box 101, with one side of the magnet 202 for attracting ferrous components on the circuit board facing the housing 201, and the other side of the magnet 202 fixedly connected to a mounting base 203. Both sides of the mounting base 203 are respectively attached to baffles 204, which are coaxially fixedly connected within the housing 201. Both the upper and lower sides of the container are provided with through grooves with an area larger than that of the mounting base 203. A partition 208 is horizontally provided below the lower surface of the mounting base 203. A spring 207 is fixedly connected between the partition 208 and the mounting base 203. A rod 306 is vertically fixedly connected to the side of the mounting base 203 near the liquid storage box 101. The lower end of the rod 306 is vertically inserted into two limiting rods 305. Two symmetrical limiting rods 305 are vertically fixedly connected to the upper and lower sides of the liquid storage box 101. A pushing component for pushing the magnet 202 toward the liquid storage box 101 is provided on the partition 208.

[0027] Please see Figure 1 as well as Figure 4Specifically, the spring 207 is sleeved on the sleeve 206 and the slide rod 205, and the slide rod 205 is coaxially slidably arranged on the through groove at the axis of the sleeve 206. The opposite ends of the slide rod 205 and the sleeve 206 are respectively fixedly connected to the mounting base 203 and the partition plate 208, and a sealing block 102 is sealed and inserted into one side of the liquid storage box 101.

[0028] In the above embodiment, the user pulls out the sealing plug 102 and places the circuit board horizontally inside, ensuring that the circuit board is horizontal within the liquid storage box 101. Since the liquid storage box 101 is not rotating at this time, the circuit board is located on the upper side inside the liquid storage box 101. Therefore, when the circuit board is lowered, because it is horizontal, it begins to immerse itself in the electroplating solution of the liquid storage box 101 and descends horizontally within the solution. Furthermore, since the circuit board contains metal components, it gradually enters the adsorption range of the magnet 202 during its descent. The metal components on the circuit board are attracted by magnet 202, thus maintaining a horizontal position and continuing to move downwards. During this process, the electrolyte can fully contact the circuit board, thereby increasing the electroplating effect. At this time, the user should use the transmission component to make the mounting base 203 start to rotate around the axis of the housing 201. Since the plug 306 fixedly connected to the mounting base 203 is within the limit rod 305, the liquid storage box 101 and the mounting base 203 can rotate synchronously. That is, during this process, the mounting base 203 can maintain contact with the liquid storage box 101, thereby allowing the mounting base 203 to continuously attract the electrolyte. The circuit board moves towards the housing 201 at a constant speed as the housing 201 rotates, until the liquid storage box 101 rotates 180 degrees. During its descent, the circuit board rotates with the liquid storage box 101 until it reaches its upper position, maintaining a certain distance from the top surface of the liquid storage box 101. During this process, the baffle 204 limits the movement of the mounting base 203, ensuring it is tightly against the baffle 204 via the sleeve 206. However, after the liquid storage box 101 rotates 180 degrees, the mounting base 203 moves to the slot of the baffle 204, at which point it can be positioned within the sleeve. Under the pulling force of the cylinder 206, it passes over the baffle 204, thereby increasing the distance between the magnet 202 and the housing 201. When the mounting base 203 and the magnet 202 have both passed over the baffle 204, the magnetism of the magnet 202 can no longer affect the iron components on the circuit board. Since the circuit board is in a horizontal state at this time, it can fall uniformly in the electroplating solution in the liquid storage box 101, thereby effectively avoiding the clamping method, which would prevent the clamping point of the circuit board from forming a plating layer. In addition, the electroplating solution is in motion during this process, thus effectively improving the uniformity of the plating layer.

[0029] Please see Figure 3 as well as Figure 4Specifically, the pushing component includes a cam 301 and a transmission component. The partition 208 is provided with a through groove for the cam 301 to pass through. The cam 301 is rotatably connected to the partition 208. During rotation, the cam 301 contacts the mounting base 203. A transmission gear 303 is fixedly connected to one side of the cam 301. A rack A304 is fixedly connected to the inner wall of the lower side of the housing 201. The rack A304 is located below the through groove on the lower side of the baffle 204. During rotation about the axis of the housing 201, the transmission gear 303 can mesh with the rack A304. The transmission assembly is used to rotate the partition 208 about the axis of the housing 201.

[0030] Please see Figure 4 Specifically, the transmission assembly includes a gear 308 and a gear ring 309. The gear ring 309 is coaxially fixedly connected to the inner wall of the housing 201, and the gear 308 is meshed with the gear ring 309. The gear 308 is fixedly connected to the output shaft of the motor 307, and the motor 307 is coaxially fixedly connected to the side of the cam 301.

[0031] In the above embodiment, the user can start the motor 307. At this time, the gear 308 fixedly connected to the output shaft of the motor 307 will start to rotate at a constant speed. Since the gear 308 is meshed on the gear ring 309, the gear 308 will start to roll on the gear ring 309, thereby driving the mounting base 203 and the liquid storage box 101 to rotate clockwise synchronously until the liquid storage box 101 rotates 180 degrees. At this time, the mounting base 203 passes the stop bar 204. That is, at this time, the mounting base 203 and the magnet 202 are both outside the stop bar 204, and the plug rod 306 fixedly connected to it will disengage from the two limit rods 305. At this time, the liquid storage box 101 cannot continue to rotate with the mounting base 203, thereby avoiding affecting the circuit board inside to continue to fall downward. At this time, the user can start the motor 307 in reverse, so that the partition 208 will start to rotate and reset. During this process, the transmission gear 303 on the side of the cam 301 will gradually contact the rack A304, thereby... The transmission gear 303 begins to rotate at a constant speed in cooperation with the rack A304 meshing with it, so that the end of the cam 301 gradually contacts the mounting base 203. At this time, the mounting base 203 begins to move linearly under the action of 302 and gradually returns to its inner side from the through groove under the stop bar 204. When the cam 301 rotates 90°, the mounting base 203 slides to its maximum limit. At this time, the distance between the mounting base 203 and the liquid storage box 101 is less than its initial distance, which makes it easier for the magnet 202 to return to its initial position. At this time, its magnetism can continue to affect the circuit board in the liquid storage box 101, thereby attracting the metal parts on the circuit board and allowing it to descend horizontally at a constant speed in the liquid storage box 101. At this time, the insertion rod 306 can be inserted into the limiting rod 305. When the motor 307 is started again, the liquid storage box 101 can rotate synchronously with it, so that the circuit board can reciprocate in the liquid storage box 101 until the electroplating is completed.

[0032] Please see Figure 1 Specifically, the liquid storage box 101 is provided with a protective component to prevent the edge of the circuit board from contacting the inner wall of the liquid storage box 101. The protective component includes an adhesive strip 401, a pressure block 402 and a driving component. Both sides of the liquid storage box 101 are provided with through grooves with the same length and width as the adhesive strip 401, and the two adhesive strips 401 are respectively fixedly connected in the through grooves. The pressure block 402 is vertically arranged on the side of the corresponding adhesive strip 401. The drive assembly is used to make the two pressure blocks 402 slide towards each other.

[0033] Please see Figure 1 as well as Figure 2Specifically, the drive assembly includes connecting rods A405, two connecting rods A405 are respectively fixedly connected to the sides of two pressure blocks 402 that are close to each other, and the ends of the two connecting rods A405 are interlaced and each is fixedly connected to a rack A407. A gear A406 is provided between the two racks A407. The gear A406 is rotatably disposed on the surface of the liquid storage box 101, and the two racks A407 are respectively meshed and connected to both sides of the gear A406.

[0034] Please see Figure 6 as well as Figure 7 Specifically, the drive assembly also includes an arc-shaped block 408, which is disposed on the side of the liquid storage box 101, with the arc surface of the arc block 408 facing away from the liquid storage box 101, and the vertical surface of the arc block 408 fixedly connected to the pressure block 402 on one side, and the arc surface of the arc block 408 is outside the baffle 204.

[0035] Please see Figure 1 as well as Figure 8 Specifically, the pressure blocks 402 on both sides are horizontally slidably mounted on their corresponding guide rods 403, and one end of the guide rod 403 is fixedly connected to the side of the liquid storage box 101. A spring A404 is sleeved on the guide rod 403, and the two ends of the spring A404 are fixedly connected to the pressure block 402 and the liquid storage box 101 respectively.

[0036] In the above embodiment, during the counterclockwise rotation and reset of the mounting base 203, since the arc surface of the arc block 408 is on the movement trajectory of the counterclockwise rotation of the magnet 202, the magnet 202 can contact the arc block 408 during the counterclockwise rotation and reset of the mounting base 203. This causes the arc block 408 to begin sliding towards the liquid storage box 101 under the action of the magnet 202. At this time, the pressure block 402 begins to move linearly along the guide rod 403, thereby compressing the spring A404 fixedly connected to it, accumulating elastic potential energy. Since a connecting rod A405 is fixedly connected to the pressure block 402, the connecting rod A405 begins to move linearly synchronously with its corresponding pressure block 402, and its end is fixed... The connected rack A407 causes the gear A406, which meshes with it, to start rotating at a constant speed. At this time, the two connecting rods A405 begin to slide towards each other, thereby causing the two pressure blocks 402 to apply lateral pressure to their corresponding adhesive strips 401 simultaneously. This causes the adhesive strips 401 to begin to deform, meaning that the pressure blocks 402 push their corresponding adhesive strips 401 into the housing 201. Therefore, before the magnet 202 returns to its original position below the liquid storage box 101, if the circuit board slides towards the left and right side walls of the liquid storage box 101, the pressure blocks 402 and adhesive strips 401 can work together to push the circuit board away, thus preventing the sides of the circuit board from contacting the inner wall of the liquid storage box 101 and causing scratches, which would affect the formation of the electroplated layer on it.

[0037] Please see Figure 1 as well as Figure 7 Specifically, the protective component also includes an adhesive strip A505. The front and rear sides of the liquid storage box 101 are provided with grooves of equal length and width to the adhesive strip A505. The adhesive strip A505 is vertically fixedly connected in the corresponding groove. On the opposite sides of the two adhesive strips A505, a pressure block A504 is vertically provided, and the pressure block A504 is close to the adhesive strip A505.

[0038] Please see Figure 2 Specifically, the upper ends of the two pressure blocks A504 are fixedly connected to connecting rods B503, and the ends of the two connecting rods B503 that are close to each other are fixedly connected to racks B502. The two racks B502 are respectively meshed and connected to both sides of the same gear B501, and the gear B501 is coaxially fixedly connected to the gear A406.

[0039] In the above embodiment, when the connecting rod A405 slides and causes the gear A406 to start rotating, the gear B501, which is coaxially fixedly connected to the gear A406, starts to rotate synchronously. At this time, the racks B502, which are meshed on both sides of the gear B501, start to slide synchronously. That is, at this time, the two connecting rods B503 start to slide towards each other, causing the two pressure blocks A504 to apply a lateral pushing force to the corresponding adhesive strip A505, causing the adhesive strip A505 to start to deform, so that the pressure block A504 can push the adhesive strip A505 into the liquid storage box 101, and then push the circuit board in the front and rear directions. This avoids the circuit board from contacting the inner wall of the liquid storage box 101 in four directions. Until the magnet 202 separates from the arc block 408, the pressure block 402 and the pressure block A504 can slide back to their original positions under the action of the spring A404, so as to push the circuit board again.

[0040] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0041] The term "fixed connection" as used in this application refers to a connection in which parts or components are fixed without any relative movement. This includes both detachable and non-detachable connections.

[0042] (1) Detachable connection: Components are fixed together using screws, splines, wedges, etc. This type of connection allows for disassembly during maintenance without damaging the parts. However, the specifications of the connectors used must be correct. (Such as the length of bolts, keys, and wedges), and tighten them properly.

[0043] (2) Non-removable connections: These mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxy-acetylene cutting for repair or replacement, these parts generally cannot be reused. Furthermore, during connection, [the following should be noted]: Pay attention to process quality, technical testing, and remedial measures (such as correction, polishing, etc.).

[0044] The sliding connection referred to in this application means that the component can slide along a linear trajectory, and the hinge referred to in this application means that the component can rotate along an axial constraint.

[0045] In some cases, the sliding connection and hinge referred to in this application may also be damped, enabling the component to maintain in the desired position.
