Description

Technical Field

[0001] This utility model belongs to the technical field of liquid replenishment devices, and more specifically, it relates to an automatic liquid replenishment device for circuit board electroplating solution. Background Technology

[0002] In modern circuit board manufacturing plants, in order to ensure product quality consistency and improve production efficiency, manufacturers often use automatic liquid replenishment devices on a large scale to replenish the electroplating solution that is constantly consumed during the electroplating process.

[0003] However, traditional devices do not have the function of fixing the circuit board during the liquid replenishment process, which can easily lead to the circuit board shaking or shifting in the electroplating tank during actual production due to the lack of fixing.

[0004] Furthermore, when the electroplating solution is replenished, its flow may impact the circuit board. Under such impact, the circuit board is more likely to deviate from its original position. The instability of the circuit board's position can easily lead to uneven contact between the electroplating solution and the circuit board surface, resulting in inconsistent plating thickness, localized missed plating, or plating defects. This not only affects the quality of the circuit board, causing a large number of unqualified products and increasing production costs, but also damages the company's reputation and reduces its market competitiveness due to product quality issues. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an automatic replenishment device for circuit board electroplating solution, thereby solving the technical problem that traditional devices in the prior art do not have the function of fixing the circuit board during the replenishment process.

[0006] The purpose and effect of this utility model's automatic replenishment device for circuit board electroplating solution are achieved by the following specific technical means: An automatic replenishment device for circuit board electroplating solution includes a support frame and multiple sets of automatic replenishment device bodies. A support plate is mounted on the support frame, and multiple sets of limiting plates and slide rails are mounted on the support plate. A motor is mounted on one side of one set of limiting plates. Multiple protective frames are mounted on the support plate, and a fixing block is mounted on one set of protective frames. A connecting column is mounted on the fixing block. A connecting wheel is fitted onto one end of the motor and the connecting column. Two sets of connecting wheels are connected by a belt. Sliding blocks are mounted on each of the multiple sets of slide rails, and first support columns are mounted on each of the multiple sets of sliding blocks. Two sets of first support columns are connected by connecting pieces. One set of connecting pieces is connected to the lower belt surface of the belt, and the other set of connecting pieces is connected to the upper belt surface of the belt.

[0007] According to a preferred embodiment, each of the multiple sets of sliding blocks is provided with a horizontal plate for support on one side, and each of the multiple sets of horizontal plates is provided with a second support column. Each of the multiple sets of first support columns and multiple sets of second support columns is fitted with a clamping pressure column.

[0008] According to a preferred embodiment, the support plate is provided with a placement frame for dripping operation, the belt passes through the placement frame, and a fixing clamping plate is provided on one side of each of the two sets of pressure columns, with one side of each of the two sets of fixing clamping plates passing through the placement frame.

[0009] According to a preferred embodiment, the placement frame has four sets of cavities, and the placement frame is provided with four sets of infrared sensors. The four sets of infrared sensors are respectively located below the cavities, and the automatic liquid replenishment device body has four sets.

[0010] According to a preferred embodiment, the four sets of automatic fluid replenishment device bodies are respectively located above the four sets of cavities, and the four sets of automatic fluid replenishment device bodies are respectively electrically connected to the four sets of infrared sensors. An L-shaped plate is provided on one side of the support plate, and the four sets of automatic fluid replenishment device bodies are all clamped on the L-shaped plate.

[0011] According to a preferred embodiment, the support plate has multiple sets of mounting slots, the multiple sets of slide rails are located in the multiple sets of mounting slots, the motor is located on one side of the support plate, and the support plate is connected to the support frame by fixing bolts.

[0012] According to a preferred embodiment, the bottom of the bearing plate is provided with multiple sets of pads, and the multiple sets of limiting plates are provided with U-shaped grooves. The two sides of the belt pass through the U-shaped grooves respectively, and the multiple sets of protective frames are symmetrically arranged.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This device, through the inclusion of a slide rail, sliding block, first support column, connecting plate, and a belt-connected structure, enables the movement of the pressure column, improving the device's positioning accuracy. The device can be driven by a motor to rotate the connecting wheel, which in turn drives the belt transmission, causing the connecting plate to move with the belt. This, in turn, causes the sliding block to slide on the slide rail, allowing the device to move the pressure column to a designated position according to actual needs. This enhances the device's ability to position the pressure column, thereby clamping and positioning the circuit board to be replenished with liquid, ensuring the stability of the dripping operation.

[0017] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model. Example:

[0018] like Figure 1 , Figure 2 , Figure 4As shown, this utility model provides an automatic replenishment device for circuit board electroplating solution, including a support frame 11 and multiple sets of automatic replenishment device bodies 12. The support frame 11 is provided with a bearing plate 13, and the bearing plate 13 is provided with multiple sets of limiting plates 14. The bearing plate 13 is provided with multiple sets of slide rails 15. One set of limiting plates 14 is provided with a motor on one side. The bearing plate 13 is provided with multiple sets of protective frames 16. One set of protective frames 16 is provided with a fixing block 17. The fixing block 17 is provided with a connecting column. One end of the motor and the connecting column are both fitted with connecting wheels. The two sets of connecting wheels are connected by a belt. Each set of slide rails 15 is provided with a sliding block 18. Each set of sliding blocks 18 is provided with a first support column. The two sets of first support columns are connected by a connecting piece 19. One set of connecting pieces 19 is connected to the lower belt surface of the belt, and the other set of connecting pieces 19 is connected to the upper belt surface of the belt. Specifically, the support frame 11 provides support for the entire device, and the bearing plate 13 serves as the core bearing platform, used to install components such as the limiting plate 14, slide rail 15, and motor, ensuring that the layout of each structure is reasonable and the operation is stable. The limiting plate 14 plays a positioning and protection role, limiting the installation position of the motor and the protective frame 16, and preventing the components from shifting during operation. The slide rail 15 provides a sliding track for the sliding block 18, ensuring that the sliding block 18 drives the subsequent clamping structure to move smoothly. The motor serves as a power source and is connected to an external controller and receives control. The belt is driven to rotate through the connecting wheel. Since the two sets of connecting plates 19 are connected to the upper belt end and the lower belt end respectively, when the belt rotates, it can drive the two sets of sliding blocks 18 to move synchronously in opposite directions along the slide rail 15, realizing the opening and closing adjustment of the clamping mechanism. The protective frame 16 is used to wrap the transmission part of the connecting wheel and the belt, preventing external impurities from interfering with the transmission, and at the same time preventing the operator from accidentally touching the moving parts, thus improving the safety of use. The fixing block 17 cooperates with the connecting column to provide stable driven support for the belt, ensuring that the belt tension is consistent during transmission and preventing slippage from affecting the transmission accuracy. Each of the multiple sets of sliding blocks 18 has a horizontal plate 21 for support on one side, and each of the multiple sets of horizontal plates 21 has a second support column. Each of the multiple sets of first support columns and multiple sets of second support columns is fitted with a clamping column 22.

[0019] Specifically, the sliding block 18 drives the second support column to move synchronously through the horizontal plate 21. The first support column and the second support column form a symmetrical support structure, providing an installation carrier for the pressure column 22. After the pressure column 22 is sleeved on the support column, the pressure column 22 achieves initial clamping and fixing of the container through the reverse movement of the two sets of sliding blocks 18. The support plate 13 is provided with a placement frame 23 for dripping operation. The belt passes through the placement frame 23. Each of the two sets of pressure columns 22 is provided with a fixing clamping plate 24 on one side. The two sets of fixing clamping plates 24 are inserted into the placement frame 23 on one side. Specifically, the placement frame 23 provides an area for liquid replenishment operations, integrating the automatic liquid replenishment device body 12 with the clamping structure to ensure that the liquid replenishment effect is applied to the electroplating container; the belt passes through the placement frame 23 to avoid component interference; the fixed clamping plate 24 cooperates with the pressure column 22 to further enhance the fixing effect on the electroplating container, especially for small or irregularly shaped containers, the fixed clamping plate 24 can penetrate deep into the placement frame 23 to form multi-directional constraints to prevent the container from tipping over; at the same time, the cavities of the placement frame 23 can separate different electroplating containers to avoid cross-contamination and adapt to the need for simultaneous liquid replenishment of multiple containers.

[0020] The placement frame 23 has four sets of cavities, and the placement frame 23 has four sets of infrared sensors 25. The four sets of infrared sensors 25 are located below the cavities, and the automatic liquid replenishment device body 12 has four sets.

[0021] Specifically, the four cavities correspond to four automatic liquid replenishment device bodies 12, which can simultaneously replenish liquid for four circuit board electroplating containers, greatly improving work efficiency. The infrared sensor 25 is installed below the cavity to detect whether an electroplating container is placed in the cavity and whether the liquid replenishment point of the electroplating container is placed below the automatic liquid replenishment device body 12. When the sensor detects that a container has been placed in the electroplating container, it can automatically trigger the corresponding automatic liquid replenishment device body 12 to start, realizing automatic control and reducing manual monitoring costs.

[0022] like Figures 2 to 4 As shown, the four sets of automatic liquid replenishment device bodies 12 are located above the four sets of cavities. The four sets of automatic liquid replenishment device bodies 12 are electrically connected to the four sets of infrared sensors 25. An L-shaped plate 26 is provided on one side of the support plate 13, and the four sets of automatic liquid replenishment device bodies 12 are all stuck on the L-shaped plate 26.

[0023] Specifically, the automatic liquid replenishment device body 12 is located above the diaphragm, ensuring that the liquid replenishment port can be aligned with the electroplating container below, avoiding liquid replenishment deviation; its electrical connection with the infrared sensor 25 allows the liquid replenishment action to be completely controlled by the sensor's detection signal, realizing closed-loop operation without manual intervention; the L-shaped plate 26 provides stable installation support for the automatic liquid replenishment device body 12, and is fixed by a snap-fit ​​method, which not only facilitates the installation, disassembly and maintenance of the device body, but also ensures its stable position during the liquid replenishment process, avoiding displacement of the liquid replenishment port due to vibration, and ensuring liquid replenishment accuracy.

[0024] Multiple sets of mounting slots are provided on the support plate 13, and multiple sets of slide rails 15 are located in the multiple sets of mounting slots. The motor is located on one side of the support plate 13, and the support plate 13 is connected to the support frame 11 by fixing bolts.

[0025] Specifically, the mounting groove provides embedded installation space for the slide rail 15, making the slide rail 15 flush with the surface of the support plate 13. This avoids the slide rail 15 protruding and causing the sliding block 18 to be obstructed, and also enhances the stability of the slide rail 15 installation, preventing the slide rail 15 from loosening after long-term use. The motor is located on one side of the support plate 13, which can avoid interference with the sliding block 18, the placement frame 23 and other components, and at the same time facilitates the wiring and maintenance of the motor. The fixing bolts rigidly connect the support plate 13 and the support frame 11, ensuring the connection between the two, distributing the weight of each component on the support plate 13, preventing the support plate 13 from deforming, and extending the overall service life of the device.

[0026] The bottom of the bearing plate 13 is provided with multiple sets of pads, and multiple sets of limiting plates 14 are provided with U-shaped grooves. The belt passes through the U-shaped grooves on both sides respectively, and multiple sets of protective frames 16 are symmetrically arranged.

[0027] Specifically, the pad at the bottom of the support plate 13 is made of anti-slip and wear-resistant material, which can adjust the horizontal height of the support plate 13 to ensure that the whole device is in a horizontal state, and avoid the sliding block 18 from shifting or the fluid replenishment from unevenness due to tilting; the U-shaped groove on the limiting plate 14 provides a passage for the belt, which not only limits the transmission path of the belt and prevents the belt from running off-center, but also avoids the belt from directly rubbing against the limiting plate 14 and causing wear; the protective frame 16 is symmetrically arranged, which can make the transmission structure on both sides of the belt bear the force evenly, ensure the stability of the belt transmission, and at the same time improve the symmetry and aesthetics of the overall structure of the device, and facilitate the replacement and calibration of components during later maintenance.

[0028] The specific usage and function of this embodiment are as follows: When using the automatic replenishment device for circuit board electroplating solution, the equipment should be prepared first: place the support frame 11 on a flat ground, adjust the support plate 13 to a horizontal state using the pads at the bottom of the support plate 13, and ensure that the support plate 13 is stably connected to the support frame 11 by the fixing bolts. Then start the motor and debug it through the external controller. Check whether the belt drives smoothly in the U-shaped groove of the limit plate 14, whether the sliding block 18 moves smoothly along the slide rail 15 in the mounting groove, and at the same time confirm that the four sets of automatic replenishment device bodies 12 are not loosely locked on the L-shaped plate 26, and that the infrared sensor 25 has normal detection function after being powered on. Next, the electroplating containers are fixed: four sets of circuit board electroplating containers to be replenished are placed into the four cavities of the placement frame 23. The motor is started by the controller, and the motor drives the connecting wheel to rotate the belt. Since the two sets of connecting plates 19 are connected to the upper belt surface and the lower belt surface respectively, when the belt rotates, it drives the two sets of sliding blocks 18 to move synchronously in opposite directions along the slide rail 15. The sliding blocks 18 drive the second support column and the pressure column 22 to move through the horizontal plate 21, so that the pressure column 22 initially clamps the container. At the same time, the fixed clamping plate 24 is inserted into the placement frame 23 to form multi-directional constraints, which completely prevents the container from tipping over or shifting. The protective frame 16 avoids interference from impurities and accidental contact by personnel during the transmission process. Then, the automatic liquid replenishment stage begins: After the infrared sensor 25 below the compartment detects that the object to be replenished has arrived, it automatically transmits a signal to the corresponding automatic liquid replenishment device body 12. The device body starts and replenishes the circuit board through the liquid replenishment port. The compartment setting of the placement frame 23 avoids cross-contamination between different containers. The four sets of devices work simultaneously, which greatly improves the liquid replenishment efficiency. After the liquid replenishment is completed, the infrared sensor 25 detects that the liquid replenishment has been completed and then controls the automatic liquid replenishment device body 12 to stop working. The controller starts the motor in reverse, so that the sliding block 18 drives the clamping structure to reset, and the electroplating container can be taken out. During routine maintenance, the automatic liquid replenishment device body 12 on the L-shaped plate 26 can be directly disassembled for inspection or replacement. The slide rail 15 is embedded for easy cleaning of debris, and the symmetrically arranged protective frame 16 also facilitates the maintenance of the transmission components.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
