Description

TECHNICAL FIELD

[0001] The utility model relates to a PCB production line, especially a VCP electroplating line. BACKGROUND

[0002] The VCP electroplating line is a conventional production line of PCB production, and the PCB 10 soaked in the chemical solution is clamped by a clamp 22 at one side in the feeding section of the VCP electroplating line and vertically downward to drip dry the chemical solution. The existing operation is that the PCB 10 slowly moves or temporarily stays in the feeding section, and a liquid collecting tank 24 is arranged below to collect the dripping chemical solution for secondary recovery. When most of the chemical solution on the PCB 10 enters the liquid collecting tank 24 and basically meets the requirements of the subsequent process, the clamp 22 drives the PCB 10 to move forward to the discharging station. A mechanical hand 23 is arranged at the discharging station, and the mechanical hand 23 sucks the PCB 10 under the driving of a blower set 21, takes the PCB 10 away from the clamp 22 and transfers the PCB 10 to a conveying belt. The blower set 21 is arranged at the top of the VCP electroplating line.

[0003] The existing technology has the following problems:

[0004] 1. The exhaust of the blower is directly discharged outside, and the energy utilization rate is low;

[0005] 2. Only vertical dripping is used, which is time-consuming and low in efficiency, and the volatilization amount of the chemical solution is large;

[0006] 3. The volatilization of the chemical solution will cause corrosion of the clamp 22 and oxidation of the PCB 10, affecting the product quality;

[0007] 4. The volatilized chemical solution has a health impact on the environment and employees. INVENTION CONTENTS

[0008] The utility model aims at providing a VCP electroplating line to solve the problems in the prior art.

[0009] The VCP electroplating line in the utility model is provided with a blower set at the top of the feeding section, a clamp is arranged to clamp and drive the PCB to move, and a liquid collecting tank is arranged at the lower part of the feeding section to collect the chemical solution dripping from the PCB;

[0010] An air blowing mechanism is further arranged at the feeding section to blow off the chemical solution of the clamp and the PCB; and the air inlet end of the air blowing mechanism is communicated with the exhaust end of the blower set.

[0011] The air blowing mechanism comprises air knives arranged opposite to each other at both sides of the clamp, and each air knife is provided with a plurality of air outlets at the side facing the clamp; and the air knives are communicated with the exhaust end of the blower set through air inlet pipes.

[0012] The air knives are horizontally arranged.

[0016] One end of the mounting frame is fixedly connected to the top of the feeding section, and the other end is fixedly connected to the air knife.

[0017] The VCP electroplating line has the advantages that four problems in the prior art are solved at the same time. The jet energy is derived from the exhaust gas of the blower set, without increasing the energy input of the production line, and the energy utilization rate is improved. The chemical solution is separated from the clamp and the PCB, the working efficiency is improved, and the volatilization amount is reduced. Therefore, the corrosion of the clamp and the oxidation degree of the PCB are minimized, and the product quality is improved. Finally, the environment can be improved, and the health condition is improved. BRIEF DESCRIPTION OF DRAWINGS

[0026] As Figures 1 to 3 shown, the VCP electroplating line in the utility model is provided with a blower set 21 at the top of the feeding section, a clamp 22 is arranged for clamping and driving the PCB 10 to move, a collecting tank 24 is arranged at the lower part of the feeding section for collecting the chemical solution falling from the PCB 10, a jet mechanism is arranged at the feeding section for blowing off the chemical solution of the clamp 22 and the PCB 10, and the air inlet end of the jet mechanism is communicated with the exhaust end of the blower set 21.

[0027] Working principle: when the PCB 10 is driven by the clamp 22 to pass through or enter the working area of the air jet mechanism, the high-pressure airflow can quickly blow away the medicine solution, improve the medicine solution collection efficiency and reduce the volatile amount. The PCB 10 can be sent to the next stage more quickly, and then the mechanical hand 23 can suck and take down.

[0030] The lower side of the air knife 31 is level with the lower end of the clamp 22. The purpose is to effectively blow and spray the PCB 10, and also to spray away the medicine solution on the clamp 22.

[0031] The outer side wall of the liquid collecting groove 24 is provided with a viewing window 25. The operator can intuitively understand the liquid collection amount.
