Description

Technical Field

[0001] The utility model relates to electroplating degreasing equipment, in particular to a vertical continuous electroplating degreasing device. Background Art

[0002] In the existing vertical continuous electroplating technology applications, the traditional oil removal method is a combination of entrance and exit lifting and step-by-step low-push mode. It falls into the slot from the entrance and is pulled into the low-push position by an ordinary linear push-pull motor, and then moves forward step by step by a step-by-step push-pull motor, and then moves from the end low-push position to the oil removal outlet position by a linear push-pull motor, and finally the hanger is raised to move the hanger out of the oil removal tank; at the same time, an IDVS vibration motor is set at the entrance, and the low-push position uses a back and forth swing hanger to drive out bubbles in the hole and oil stains on the board surface. However, as customer product requirements become higher and higher, for blind hole boards above the million level, it is impossible to completely clean the board surface and the inner wall of the hole, so anti-plating and core wrapping in the hole will still occur, which directly affects the product qualification rate. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a vertical continuous electroplating degreasing device which can effectively disperse bubbles in plate holes, help to pour medicine into the holes, and improve the wetness and cleanliness of the hole bottom in view of the shortcomings of the existing technology.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions.

[0005] A vertical continuous electroplating degreasing device comprises a frame, a degreasing tank and a traveling mechanism arranged above the degreasing tank, a moving end of the traveling mechanism is provided with a hanger for clamping a PCB board, the traveling mechanism is used to drive the hanger to move back and forth along the degreasing tank, ultrasonic vibration plates are respectively provided on the inner walls on both sides of the degreasing tank, an ultrasonic generator on the ultrasonic vibration plate faces the PCB board, and a side spray mechanism is arranged oppositely in the degreasing tank, and the nozzle of the side spray mechanism faces the PCB board.

[0006] Preferably, the ultrasonic vibration plate is provided with a plurality of ultrasonic generators distributed in a matrix.

[0007] Preferably, a plurality of side spray mechanisms are provided in the degreasing tank, and the side spray mechanisms include a plurality of spray heads evenly distributed vertically.

[0008] Preferably, the walking mechanism includes a chain transmission mechanism and a driving motor for driving the chain transmission mechanism to move, and the hanger is arranged at the moving end of the chain transmission mechanism.

[0009] Preferably, the frame is provided with an inlet end lifting mechanism and an outlet end lifting mechanism, the inlet end lifting mechanism is used to transport the hanger holding the PCB board downward to the loading end of the walking mechanism, and the outlet end lifting mechanism is used to drive the hanger holding the PCB board at the unloading end of the walking mechanism to rise.

[0010] In the vertical continuous electroplating degreasing device disclosed by the utility model, the degreasing tank and the traveling mechanism are provided on the frame, and the traveling mechanism is used to drive the hanger holding the PCB board to move horizontally in the degreasing tank, so that the PCB board is continuously immersed in the solution of the degreasing tank during the horizontal movement. When the PCB board moves between the two side spray mechanisms, the nozzle of the side spray mechanism drives the liquid medicine to spray to the PCB board, and under the action of the side spray, the liquid medicine is effectively poured into the hole and flows along the board surface, which can increase the wetness and cleanliness of the hole bottom. Because the two ultrasonic vibration plates in the degreasing tank are arranged on both sides of the PCB board, the bubbles in the plate holes are vibrated and driven out under the ultrasonic vibration of multiple ultrasonic generators, which further increases the wetness of the hole bottom. In the electroplating process, the board surface anti-plating and hole leakage can be better eliminated, thereby improving the quality of the electroplating degreasing process.

[0017] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0018] The utility model discloses a vertical continuous electroplating degreasing device, combined with Figures 1 to 6As shown, it includes a frame 1, on which a degreasing tank 2 and a walking mechanism 3 are provided above the degreasing tank 2, a moving end of the walking mechanism 3 is provided with a hanger 4 for clamping a PCB board 100, and the walking mechanism 3 is used to drive the hanger 4 to move back and forth along the degreasing tank 2, and ultrasonic vibration plates 5 are respectively provided on the inner walls of both sides of the degreasing tank 2, and an ultrasonic generator 50 on the ultrasonic vibration plate 5 faces the PCB board 100, and a side spray mechanism 6 is provided in the degreasing tank 2, and a nozzle 60 of the side spray mechanism 6 faces the PCB board 100.

[0019] In the above structure, the frame 1 is provided with the degreasing tank 2 and the walking mechanism 3, and the walking mechanism 3 is used to drive the hanger 4 holding the PCB board 100 to move horizontally in the degreasing tank 2, so that the PCB board 100 is continuously immersed in the solution of the degreasing tank 2 during the horizontal movement. When the PCB board 100 moves between the two side spray mechanisms 6, the nozzle 60 of the side spray mechanism 6 drives the liquid medicine to spray to the PCB board 100. Under the action of the side spray, the liquid medicine is effectively poured into the hole and flows along the board surface, which can increase the wetness and cleanliness of the hole bottom. Because the two ultrasonic vibration plates 5 in the degreasing tank 2 are arranged on both sides of the PCB board 100, the bubbles in the board hole are vibrated and driven out under the ultrasonic vibration of multiple ultrasonic generators 50, which further increases the wetness of the hole bottom. In the electroplating process, it can better eliminate the board surface anti-plating and hole leakage phenomenon, thereby improving the quality of the electroplating degreasing process.

[0020] In order to make the ultrasonic generators 50 evenly distributed relative to the surface of the PCB board 100, in this embodiment, see Figure 5 The ultrasonic vibration plate 5 is provided with a plurality of ultrasonic generators 50 distributed in a matrix.

[0021] As a preferred method, see Figure 6 The degreasing tank 2 is provided with a plurality of side spray mechanisms 6, and the side spray mechanisms 6 include a plurality of spray heads 60 evenly distributed up and down. In practical applications, the spray heads 60 can cooperate with water pumps and water pipes to absorb the liquid medicine in the degreasing tank 2, thereby forming a liquid medicine circulation loop.

[0022] See also Figure 3 and Figure 4 In this embodiment, the walking mechanism 3 includes a chain transmission mechanism 30 and a driving motor for driving the chain transmission mechanism 30 to move, and the hanger 4 is arranged at the moving end of the chain transmission mechanism 30. Among them, this embodiment preferably adopts a continuous transmission hanger mode, which can make the medicine contact with the board surface evenly, thereby achieving the function of cleaning the board surface.

[0023] This embodiment also has a mechanism for lifting and loading materials at the front and rear ends, see Figure 1 The frame 1 is provided with an inlet end lifting mechanism 7 and an outlet end lifting mechanism 8. The inlet end lifting mechanism 7 is used to transport the hanger 4 holding the PCB board 100 downward to the loading end of the walking mechanism 3, and the outlet end lifting mechanism 8 is used to drive the hanger 4 holding the PCB board 100 at the unloading end of the walking mechanism 3 to rise.

[0024] Compared with the prior art, the utility model changes the low-push mode to a combination of ultrasonic vibration, continuous transmission and side spraying, with the aim of increasing ultrasonic vibration to effectively disperse the bubbles in the hole, so as to increase the wetness of the hole bottom and achieve the cleanliness of the inner wall of the hole to meet the requirements; at the same time, the utility model adopts a continuous transmission hanger method to more effectively make the medicine contact with the board surface evenly, so as to achieve the function of cleaning the board surface; in addition, the utility model adopts a side spraying method to increase the hole filling capacity, so that the medicine can be more fully poured into the hole, so as to more effectively clean and moisten the inner wall of the hole, and better meet the process requirements.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the technical scope of the present invention should be included in the scope of protection of the present invention.
