Description

Technical Field

[0001] The utility model relates to the technical field of PCB board etching, in particular to a PCB board etching device. Background Technique

[0002] The PCB board, also known as the printed circuit board, is an important electronic component, a support for electronic components, and a carrier for the electrical connection of electronic components. The printed board has developed from single-layer to double-sided, multi-layer and flexible, and still maintains its respective development trends. Due to the continuous development towards high precision, high density and high reliability, continuously reducing volume, reducing costs and improving performance, the printed board still maintains strong vitality in the development of future electronic devices.

[0003] When the PCB board is produced, it will go through the etching process. The traditional PCB board etching device requires manual loading and unloading during use. The waste liquid after etching is harmful to the human body. Therefore, the operator needs to concentrate highly to work to avoid accidents. However, manual operation is prone to fatigue and safety accidents are likely to occur. Content of the Utility Model

[0004] The purpose of the utility model is to provide a PCB board etching device that is convenient for loading and unloading.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows.

[0006] A PCB board etching device includes a device body. Feeding ports are provided on both sides of the device body. Mounting plates are installed on the inner walls on both sides of the device body. A conveyor belt is arranged at the feeding port. Both sides of the conveyor belt are respectively connected to the two mounting plates. An etching solution storage is installed on the inner wall of the device body. A feeding port is connected to the outer surface of the etching solution storage near the upper end. A sprayer is installed on the upper surface of the mounting plate. The sprayer is connected to the etching solution storage. A shunt pipe is connected to the outer surface of the sprayer. A plurality of nozzles are installed on the outer surface of the shunt pipe. A waste liquid tank is installed on the inner wall of the device body. A connecting pipe is connected to the upper end of the waste liquid tank. A liquid collecting tank is installed at the upper end of the connecting pipe. A filter screen is installed on the inner wall of the liquid collecting tank. A sewage discharge port is connected to the outer surface of the waste liquid tank near the lower end. A driving component is installed on the inner wall of the device body near the upper end. The driving component is connected to a telescopic component. The lower end of the telescopic component is connected to a clamp. The etching solution storage is located at the inner end of the body, and the waste liquid tank is located in the middle of the body.

[0007] It can be seen that when the device is in use, since a conveyor belt is provided at the material conveying port and the conveyor belt is connected to the mounting plate, the two conveyor belts can be used for the conveying of loading and unloading. Also, since a driving assembly is installed on the device body, and the telescopic assembly is connected to the driving assembly and a clamp is installed, when the material enters the device, the material can be clamped by the clamp, and can be transported by the driving assembly and the telescopic assembly. After the clamp transports the material to the liquid collection tank, since the sprayer is connected to the etching solution storage tank, the etching solution storage tank can store the etching solution. And since the sprayer is connected to the shunt pipe and the shunt pipe is equipped with multiple nozzles, the nozzles spray the etching solution on the surface of the PCB board for etching. Also, since the liquid collection tank is installed with a filter screen and is connected to the connecting pipe, the waste liquid after etching will flow into the waste liquid tank through the connecting pipe for temporary storage. When the etching is completed, the clamp will then clamp the material to the surface of the conveyor belt and transport it to the next process. It is necessary to regularly supplement the etching solution in the etching solution storage tank through the feeding port, and regularly discharge the waste liquid in the waste liquid tank through the sewage discharge port. Therefore, it can avoid safety accidents caused by manual contact with the waste liquid, and increase the production efficiency. The etching solution storage tank is located at the inner end of the body, and the waste liquid tank is located in the middle of the body, which is beneficial to shortening the length of the connecting pipe for waste liquid transportation, shortening the transportation flow path length between the etching solution storage tank and the sprayer, facilitating maintenance, and reducing the manufacturing cost and maintenance cost.

[0008] Furthermore, there are two sets of etching solution storage tanks, and the two sets of etching solution storage tanks are symmetrically arranged.

[0009] Because the two sets of etching solution storage tanks are symmetrically arranged, the two sets of etching solution storage tanks can increase the storage capacity of the etching solution, and spray the etching solution through two sprayers, increasing the etching efficiency and improving the production efficiency.

[0010] Furthermore, a collection box is provided on the lower side of the conveyor belt. The outer surface of the collection box is connected to the inner wall of the device body. Through grooves are opened on both sides of the inner wall of the collection box, and two through grooves are each connected to a diversion pipe, and the ends of the two diversion pipes are both connected to the waste liquid tank.

[0011] Since the collection box is connected to the device body and two through grooves are opened, and the through grooves are connected to the diversion pipes, the etching waste liquid remaining on the conveyor belt will drip into the collection box after leaving, and flow into the diversion pipes through the through grooves. Also, since the diversion pipes are connected to the waste liquid tank, the waste liquid can enter the waste liquid tank for temporary storage, avoiding damage to the device components by the waste liquid inside the device.

[0012] Furthermore, a maintenance door is hinged on the side of the device body.

[0013] The maintenance door can play a protective role, and is convenient for supplementing the etching solution and discharging the waste liquid, increasing the convenience of maintenance.

[0014] Further, liquid level viewing windows are provided on the sides of both etching solution storage tanks and the waste liquid tank, and the liquid level viewing windows are provided with scale lines.

[0015] The liquid level viewing windows can observe the liquid levels inside the etching solution storage tanks and the waste liquid tank, so as to facilitate the operator to supplement the etching solution and discharge the waste liquid in a timely manner, and the scale lines can facilitate the determination of the capacity.

[0016] Further, etching solution concentration detectors are provided inside both etching solution storage tanks.

[0017] The etching solution concentration detectors can monitor the concentration of the etching solution, avoid production accidents caused by abnormal etching solution concentration, and cause losses. Brief Description of the Drawings

A feeding port 21 is connected to the outer surface of the etching solution storage 20 near the upper end. A sprayer 22 is installed on the upper surface of the mounting plate 12. The sprayer 22 is connected to the etching solution storage 20. A shunt pipe 23 is connected to the outer surface of the sprayer 22. A plurality of nozzles 24 are installed on the outer surface of the shunt pipe 23. A waste liquid tank 30 is installed on the inner wall of the device body 10.

A driving assembly 40 is installed on the inner wall of the device body 10 near the upper end. The driving assembly 40 is connected to a telescopic assembly 41. The lower end of the telescopic assembly 41 is connected to a fixture 42. The etching solution storage 20 is located at the inner end of the body 10, and the waste liquid tank 30 is located in the middle of the body 10.

[0025] When the device is in use, since the feeding port 11 is provided with the conveyor belt 13 and the conveyor belt 13 is connected to the mounting plate 12, the two conveyor belts 13 can be used for the feeding and discharging transportation. Also, since the device body 10 is equipped with the driving assembly 40 and the telescopic assembly 41 is connected to the driving assembly 40 and is equipped with the fixture 42, when the material enters the device, the fixture 42 can clamp the material, and the material can be transported through the driving assembly 40 and the telescopic assembly 41. After the fixture 42 transports the material onto the liquid collecting tank 32, since the sprayer 22 is connected to the etching solution storage 20, the etching solution storage 20 can store the etching solution. And since the sprayer 22 is connected to the shunt pipe 23 and the shunt pipe 23 is equipped with a plurality of nozzles 24, the nozzles 24 spray the etching solution on the surface of the PCB board for etching. Also, since the liquid collecting tank 32 is equipped with the filter screen 33 and is connected to the connecting pipe 31, the waste liquid after etching will flow into the waste liquid tank 30 through the connecting pipe 31 for temporary storage. When the etching is completed, the fixture 42 then clamps the material onto the surface of the conveyor belt 13 and transports it to the next process. Since the etching solution storage 20 is connected to the feeding port 21, the etching solution in the etching solution storage 20 needs to be replenished regularly through the feeding port 21. And since the waste liquid tank 30 is connected to the sewage outlet 34, the waste liquid in the waste liquid tank 30 can be discharged regularly through the sewage outlet 34. Therefore, it can avoid manual contact with the waste liquid and cause safety accidents, and improve the production efficiency.

Since the device body 10 is hinged to the maintenance door 14, the maintenance door 14 can play a protective role, and is convenient for replenishing the etching solution and discharging the waste liquid, increasing the convenience of maintenance.

[0029] Specifically, liquid level viewing windows 60 are provided on the sides of the two etching solution reservoirs 20 and the waste liquid tank 30. The liquid level viewing windows 60 are provided with scale lines. Since the liquid level viewing windows 60 are provided on both the etching solution reservoirs 20 and the waste liquid tank 30, and the liquid level viewing windows 60 are provided with scale lines, the liquid levels inside the etching solution reservoirs 20 and the waste liquid tank 30 can be observed through the liquid level viewing windows 60, so as to facilitate the operator to replenish the etching solution and discharge the waste liquid in a timely manner, and the scale lines can facilitate the determination of the capacity.
