Description

Technical Field

[0001] The utility model relates to the technical field of cleaning of printed circuit board exposure equipment, in particular to an auxiliary cleaning device for a printed circuit board exposure equipment which is convenient for recycling. Background Technique

[0002] In the process of manufacturing printed circuit boards, exposure equipment is often used. It can create a light exposure scene, enabling the equipment to transfer the patterns and texts on the circuit board to the photosensitive glue and form a cured pattern, which can pave the way for subsequent processes such as etching and plate making. Such printed circuit board exposure equipment often needs to be regularly cleaned in the functional area by an auxiliary cleaning device.

[0003] The auxiliary cleaning device for printed circuit board exposure equipment can often only achieve a single flushing and cleaning function for the internal functional area of the exposure equipment. It requires manual operation to hold the nozzle of the spray head and align it with the exposure equipment, and it is not easy to achieve automatic flexible fixing and disassembly on the exposure equipment, which leads to inconvenient operation of the device. Moreover, simple water washing cleaning also has the problem of insufficient cleaning effect. Additionally, it is not easy to automatically recycle the wastewater generated during the cleaning process, and these waste liquids flowing directly to the ground will cause pollution. Based on this, we propose a new type of auxiliary cleaning device for printed circuit board exposure equipment that is convenient for recycling to better meet the cleaning requirements of printed circuit board exposure equipment. Content of the Utility Model

[0004] The purpose of the utility model is to provide an auxiliary cleaning device for a printed circuit board exposure equipment that is convenient for recycling, so as to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an auxiliary cleaning device for a printed circuit board exposure equipment that is convenient for recycling, including a frame, a liquid outlet branch pipe for cleaning, and a waste liquid recovery branch pipe. On both sides inside the frame, a cleaning liquid storage tank and a waste liquid recovery tank are respectively welded. One end of the liquid outlet branch pipe for cleaning is connected to the cleaning liquid storage tank. An ultrasonic generator is installed on the outer side wall of the cleaning liquid storage tank. Transducer vibrators and spray heads are sequentially and evenly installed on the liquid outlet branch pipe for cleaning.

Corrosion-resistant pumps communicated with the liquid outlet branch pipe for cleaning and the waste liquid recovery branch pipe through hoses are respectively installed on the outer side walls of the cleaning liquid storage tank and the waste liquid recovery tank. Automatic adsorption and fixing mechanisms are installed at the bottoms of the liquid outlet branch pipe for cleaning and the waste liquid recovery branch pipe. The automatic adsorption and fixing mechanism includes a micro vacuum pump, a housing, a gas guide pipe, and a vacuum suction cup. The housing is respectively welded to the bottoms of the liquid outlet branch pipe for cleaning and the waste liquid recovery branch pipe. The vacuum suction cup and the micro vacuum pump are respectively installed at both ends of the bottom of the housing. The gas guide pipe is connected between the vacuum suction cup and the micro vacuum pump.

[0006] Preferably, two universal casters are evenly installed at the bottom of one end of the frame.

[0007] Preferably, the inner side walls of the cleaning liquid storage tank and the waste liquid recovery tank are both provided with Teflon non-stick coatings, and a liquid discharge port is provided at the bottom of the waste liquid recovery tank.

[0008] Preferably, the automatic adsorption and fixing mechanism further includes an inflation reserved pipe and a solenoid valve. The inflation reserved pipe is arranged at the top of the air guide pipe, and the solenoid valve is installed on the inflation reserved pipe.

[0009] Preferably, an assembly vertical rod is welded to the top of the transducer oscillator, and a threaded connection is formed between the assembly vertical rod and the liquid outlet branch pipe for cleaning.

[0012] Preferably, a docking port matching the corrosion-resistant pump is arranged at the top of the filter net groove main body.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] (1) By installing an ultrasonic generator and a corrosion-resistant pump, etc., the auxiliary cleaning device for the printed circuit board exposure equipment that is convenient for recycling optimizes its own performance. On the one hand, the cleaning liquid storage tank and the corrosion-resistant pump thereon can automatically introduce the cleaning liquid into the liquid outlet branch pipe for cleaning, and then evenly spray it onto the exposure machine equipment through the nozzle to achieve the flushing function. Moreover, the transducer oscillator extending into the exposure machine equipment can cooperate with the ultrasonic generator connected to it through a wire, so that ultrasonic waves radiate forward in the cleaning liquid in a sparse and dense manner, causing the liquid to flow and generating tens of thousands of tiny bubbles. These tiny bubbles existing in the liquid vibrate and change under the action of the sound field, thereby destroying the insoluble dirt and dispersing them in the cleaning liquid, achieving an efficient cleaning effect. On the other hand, by starting the corrosion-resistant pump on the waste liquid recovery tank, the waste liquid generated by cleaning can be automatically recovered through the adsorption pipe head, which is beneficial to improving the cleaning environment and reducing the problem of wastewater scattering and pollution;

Thus, it is convenient to install the liquid outlet branch pipe and the waste liquid recovery branch pipe inside the functional area of the exposure machine equipment for cleaning and recycling processing. Moreover, by using the inflation reserved pipe with an electromagnetic valve installed on the gas guide pipe, it is convenient to automatically supplement air inside the adsorption structure, which is beneficial to automatically release the adsorption and fixation effect and realize the quick disassembly between the device and the exposure machine equipment;

[0016] (3) The auxiliary cleaning device for the printed circuit board exposure equipment that is convenient for recycling is equipped with a driving seat, a waste liquid recovery tank, etc. When the device is actually operating, the waste liquid recovered and pumped in by the corrosion-resistant pump on the waste liquid recovery tank will be introduced into the main body of the filter mesh tank through the connection interface, and then the impurities in the waste liquid will be filtered through the filter holes on the main body of the filter mesh tank and retained inside the main body of the filter mesh tank, while the waste liquid is filtered out. After one cleaning process, the user can drive the driving seat to automatically rise and separate from the waste liquid recovery tank through the electric slide rail and the corresponding electric slider, exposing the main body of the filter mesh tank installed below by screws. At this time, it is convenient to disassemble the main body of the filter mesh tank for cleaning the filter residue. And for the filtered waste water, the user can directly discharge it by opening the liquid discharge port set at the bottom of the waste liquid recovery tank. This makes the device convenient for filtering the waste liquid and avoiding direct discharge of the waste liquid to pollute the environment. BRIEF DESCRIPTION OF THE DRAWINGS
