Description

Technical Field

[0001] This utility model relates to the field of electroplating technology, and in particular to a flybar cleaning device for electroplating lines. Background Technology

[0002] Electroplating lines are devices that operate continuously in multiple chemical tanks. Circuit boards produced are clamped onto flybars using fixtures and then automatically lifted to their corresponding chemical tanks by a crane. However, the inventors discovered in practice that while copper-plated circuit boards can be washed in a cleaning tank, only the circuit boards themselves are cleaned; residual chemicals on the flybars or fixtures remain. This leads to chemical contamination when the flybars are lifted from different tanks, causing water to drip onto other tanks and flybars. Furthermore, in pattern electroplating processes, copper-plated circuit boards require a tin layer as a resist layer for alkaline etching. Since electroplating lines use acidic chemicals, residual chemicals on the flybars can drip onto the tin-plated circuit boards, corroding the tin layer and causing etching defects such as gaps and open circuits, affecting quality yield and the first-pass yield of subsequent processes. Utility Model Content

[0003] Therefore, it is necessary to provide a flybar cleaning device for electroplating lines that can effectively clean residual chemicals from flybars or clamps.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A flybar cleaning device for electroplating lines includes a water washing tank and two support plates disposed above the two opposite walls of the water washing tank. A PVC horizontal pipe is installed on each support plate along the horizontal direction, and a plurality of nozzles facing the flybar are installed on each PVC horizontal pipe at predetermined intervals. The device also includes a detection component for detecting whether the flybar is located above the PVC horizontal pipe. The water inlet ends of the two PVC horizontal pipes are connected to a water inlet pipe, and a solenoid valve is provided on the water inlet pipe. The solenoid valve is electrically connected to the detection component to automatically control the start and stop of the solenoid valve according to the signal of the detection component.

[0005] Furthermore, the top of the support plate is bent and extended to form a baffle, and the nozzle is located below the baffle.

[0006] Furthermore, the nozzle is fixed to the PVC horizontal pipe by a clamping structure; the clamping structure includes a first clamping arm connected to the bottom of the nozzle, a second clamping arm sleeved on the PVC horizontal pipe, and connecting bolts respectively passing through the corresponding connecting holes opened on the first clamping arm and the second clamping arm.

[0007] Furthermore, the water inlet pipe is also equipped with a water inlet control switch for adjusting the water inlet volume.

[0008] Furthermore, the inner sidewall of the support plate is provided with a number of reinforcing ribs at intervals, the top of the reinforcing ribs is connected to the baffle, and the reinforcing ribs are provided with clearance holes at the positions corresponding to the PVC horizontal pipes. The PVC horizontal pipes pass through the clearance holes and are mounted on the inner wall of the clearance holes.

[0009] Furthermore, a support base is provided on the support plate near the water inlet end of the PVC horizontal pipe, and a snap-fit ​​groove adapted to the shape of the PVC horizontal pipe is provided on the support base, and the PVC horizontal pipe is snap-fitted and fixed in the snap-fit ​​groove.

[0010] Furthermore, the detection component is an infrared sensor installed at a predetermined height on the side wall of the washing tank.

[0011] By adopting the above technical solution, the present utility model embodiment has at least the following beneficial effects: The present utility model embodiment sets a PVC horizontal pipe with a nozzle on the support plate above the water washing tank, and realizes automatic control of spraying by using the electrical connection between the detection component and the solenoid valve. It can effectively clean the residual chemicals on the fly bar, thus avoiding cross-contamination between different chemical tanks, and also preventing residual chemicals from dripping and corroding the tin-plated circuit board, reducing quality problems such as line gaps and open circuits, and improving the PCB quality yield.

[0012] This invention utilizes a PVC horizontal pipe with nozzles horizontally mounted on a support plate above the opposite side walls of the washing tank. The PVC horizontal pipe has a nozzle at predetermined intervals, effectively cleaning residual chemicals from the flybars or clamps. This prevents contamination of other chemical tanks and avoids residual chemicals dripping onto the circuit board, thus preventing subsequent corrosion of the tin-plated circuit board by residual chemicals, reducing quality issues such as gaps and open circuits, and improving PCB quality yield. Furthermore, automatic spray control is achieved through an electrical connection between a detection component and a solenoid valve. When the detection component detects that the flybar has been lowered into the washing tank and is below the PVC horizontal pipe, the solenoid valve automatically activates, spraying the flybar and clamps with water through the nozzles. The solenoid valve automatically closes after the flybar is removed, thus avoiding water waste. Attached Figure Description

[0020] like Figures 1-3 As shown, an optional embodiment of this utility model provides a flybar cleaning device for an electroplating line, including a water washing tank 1 and two support plates 3 disposed above the two opposite walls of the water washing tank 1. Each support plate 3 is equipped with a PVC horizontal pipe 5 along the horizontal direction, and each PVC horizontal pipe 5 is equipped with a plurality of nozzles 7 facing the flybar at predetermined intervals. The device also includes a detection component 8 for detecting whether the flybar is located above the PVC horizontal pipe 5. The water inlet ends of the two PVC horizontal pipes 5 are connected to a water inlet pipe 6, and a solenoid valve 9 is provided on the water inlet pipe 6. The solenoid valve 9 is electrically connected to the detection component 8 to automatically control the start and stop of the solenoid valve 9 according to the signal of the detection component 8.

[0021] In this embodiment, the water washing tank 1 is used to clean the copper-plated circuit board. After cleaning, the circuit board is then tin-plated.

[0022] This embodiment of the invention utilizes a PVC horizontal pipe 5 with nozzles 7 horizontally mounted on a support plate 3 above the opposite side walls of the washing tank 1. A nozzle 7 is positioned at predetermined intervals (e.g., 20cm) on the PVC horizontal pipe 5, effectively cleaning residual chemicals from the flybars or clamps. This prevents contamination of other chemical tanks and avoids residual chemicals dripping onto the circuit board, thus preventing subsequent corrosion of the tin-plated circuit board by residual chemicals, reducing quality issues such as circuit gaps and open circuits, and improving PCB quality yield. Furthermore, automatic spray control is achieved through the electrical connection between the detection component 8 and the solenoid valve 9. When the detection component 8 detects that the flybar has been lowered into the washing tank 1 and is below the PVC horizontal pipe 5, the solenoid valve 9 automatically activates, spraying the flybar and clamps with the nozzles 7. The solenoid valve 9 automatically closes after the flybar is removed, thus avoiding water waste.

[0023] In one optional embodiment of this utility model, such as Figures 1-3 As shown, the top of the support plate 3 is bent and extended to form a baffle 31, and the nozzle 7 is located below the baffle 31. In this embodiment, by setting the baffle 31 on the support plate 3 and placing the nozzle 7 below the baffle 31, it is possible to prevent cleaning water from splashing outside the washing tank 1, thus ensuring stable cleaning operation.

[0024] In one optional embodiment of this utility model, such as Figures 1-3 As shown, the nozzle 7 is fixed to the PVC horizontal pipe 5 by a clip structure. The clip structure includes a first clamping arm 71 connected to the bottom of the nozzle 7, a second clamping arm 72 sleeved on the PVC horizontal pipe 5, and connecting bolts 73 respectively passing through corresponding connecting holes on the first clamping arm 71 and the second clamping arm 72. In this embodiment, the nozzle 7 is a clip-on nozzle 7, which is sleeved on the PVC horizontal pipe 5 by the first clamping arm 71 and the second clamping arm 72, and fastened by the connecting bolts 73, thereby facilitating the disassembly and installation of the nozzle 7. In practical applications, the nozzle 7 sprays in a wide fan shape, which can effectively cover the residual liquid area on the surface of the spray bar, reduce cleaning dead corners, and thus improve cleaning efficiency.

[0025] In practical implementation, the connection method of the clip can be flexibly selected: it can be a double-sided screw-locking form, or as shown in Figure 3, a single-sided pivot 74 rotation (rotational connection is achieved by the pivot hole of the first clamping arm 71) and single-sided screw-locking structure.

[0026] In one optional embodiment of this utility model, such as Figures 1-3As shown, the water inlet pipe 6 is also equipped with a water inlet control switch 61 for adjusting the water inlet volume. In this embodiment, by connecting the water inlet pipe 6 to the water inlet control switch 61, the staff can flexibly adjust the water flow rate according to the actual cleaning needs, thereby optimizing the spray intensity and ensuring that the spray can reach the fly bar.

[0027] In one optional embodiment of this utility model, such as Figures 1-3 As shown, the inner wall of the support plate 3 is provided with a plurality of reinforcing ribs 32 at intervals. The top of the reinforcing ribs 32 is connected to the baffle 31. The reinforcing ribs 32 have clearance holes 320 at the positions corresponding to the PVC horizontal pipes 5. The PVC horizontal pipes 5 pass through the clearance holes 320 and are supported on the inner wall of the clearance holes 320. In this embodiment, by setting the reinforcing ribs 32 at intervals on the support plate 3 and connecting the top of the reinforcing ribs 32 to the baffle 31, the overall structural strength of the support plate 3 can be enhanced. In addition, the clearance holes 320 at the positions corresponding to the PVC horizontal pipes 5 allow the PVC horizontal pipes 5 to pass through and be supported on the inner wall of the clearance holes 320, ensuring that the PVC horizontal pipes 5 can be positioned and aligned on the support plate 3. It can also disperse the stress of the PVC horizontal pipes 5, prevent the PVC horizontal pipes 5 from shaking, and further improve reliability.

[0028] In one optional embodiment of this utility model, such as Figures 1-3 As shown, a support base 33 is provided on the support plate 3 near the water inlet end of the PVC horizontal pipe 5. The support base 33 has a snap-fit ​​groove 330 that matches the shape of the PVC horizontal pipe 5, and the PVC horizontal pipe 5 is snapped and fixed within the snap-fit ​​groove 330. In this embodiment, by providing a support base 33 on the support plate 3 near the water inlet end of the PVC horizontal pipe 5 and snapping the PVC horizontal pipe 5 into the snap-fit ​​groove 330, the position of the PVC horizontal pipe 5 at the water inlet end is conveniently and securely secured, preventing the pipe from detaching due to high-pressure water flow impact, and further improving the overall reliability of the cleaning device.

[0029] In one optional embodiment of this utility model, such as Figures 1-3 As shown, the detection component 8 is an infrared sensor installed at a predetermined height on the side wall of the washing tank 1. In this embodiment, the infrared sensor monitors the position of the fly bar or the water level in the washing tank 1 in real time, realizing automatic detection and control of the cleaning process.
