Description

Mesh belt cleaning equipment water quality control agency

This creation is about a kind of cleaning equipment, especially a water quality control mechanism for mesh belt cleaning equipment that can detect water quality in advance.

There are quite a few steps in the processing of circuit boards. One of the steps is to "wash" the circuit boards during processing. This step is arranged after the development of the circuit boards and is performed by a water washing tank. This washing step The circuit board is mainly rinsed with water to remove the sludge accumulated on the circuit board after development for subsequent processing steps.

Currently, the commonly used circuit board cleaning equipment is to install the conductivity meter in the inlet tank of the cleaning equipment and detect the water quality of the inlet tank. Since the inlet tank is set at the end of the cleaning equipment, the water quality in the inlet tank is usually the cleanest. If the water quality of the cleanest water inlet is not clean enough, clean water needs to be put in. However, in practice, when the circuit board is cleaned at the front end and transported to the water inlet, the cleaning effect is still not good, so the conventional circuit board cleaning equipment still has The need for improvement.

In view of this, how to eliminate the above-mentioned deficiencies is the technical difficulty that the creator of this case wants to solve; therefore, based on many years of experience in the related industry, the creator of this case has finally made improvements after years of painstaking research and attempts. Those who successfully developed and completed this case and brought this new model into being to improve its efficacy.

In view of the above shortcomings, the water quality control mechanism of the new mesh belt cleaning equipment includes: an inlet tank with a water inlet valve at one end; a first cleaning tank with a detector and a drain valve. The first cleaning tank is connected to the water inlet; and a control unit is electrically connected to the water inlet valve, the detector and the drain valve. The control unit provides a predetermined resistance value to be set to the detector. The resistance value of the water in the first cleaning tank is detected. When the resistance value of the water is greater than the predetermined resistance value, the control unit sends a signal to activate the drainage valve to drain the water, and then activates the water inlet valve to input water, so that When the resistance value of the water is lower than the predetermined resistance value, the water inlet valve is closed; the water in the first cleaning tank and the water inlet tank are sequentially provided to clean at least one printed circuit board, and the impurities and dirt on the printed circuit board are removed during the cleaning process. It falls off and enters the water, causing the resistance value of the water to change. When the resistance value of the water is greater than the predetermined resistance value, drainage and water inflow are performed until the resistance value of the water is lower than the predetermined resistance value, thereby judging the printed circuit board. Cleanliness.

In order to facilitate the explanation of the content of this new model and the effects it can achieve, specific embodiments are listed in conjunction with the drawings. Please refer to the first and second figures. The water quality control mechanism of the new mesh belt cleaning equipment includes:

An inlet water tank 10 has a first accommodating space 11 inside. A water inlet valve 111 is provided at one end of the water inlet water tank 10. Water is input from the water inlet valve 111 to the first accommodating space 11.

A first cleaning tank 20 has a second accommodating space 21 inside. A detector 22 is provided in the second accommodating space 21. The first cleaning tank 20 is connected with the water inlet 10 so that the first cleaning tank 20 is connected with the water inlet 10. The water in the accommodation space 11 flows into the second accommodation space 21 , and the first cleaning tank 20 is provided with a drain valve 23 .

In this embodiment, the detector 22 is a conductivity meter.

A control unit 30 is electrically connected to the water inlet valve 111, the detector 22 and the drain valve 23. The control unit 30 provides for setting a predetermined resistance value so that the detector 22 detects the first The resistance of the water in the cleaning tank 20.

A backstop unit 40 is disposed between the water inlet trough 10 and the first cleaning tank 20 . The backstop unit 40 allows water to flow from the water inlet trough 10 into the first cleaning tank 20 in one direction.

Please refer to the third figure. In this embodiment, at least one second cleaning tank 50 is disposed between the water inlet 10 and the first cleaning tank 20 . Both ends of the second cleaning tank 50 are connected to the water inlet 10 respectively. Connected to the first cleaning tank 20, a backstop unit 40 is respectively provided between the inlet tank 10 and the second cleaning tank 50 and between the second cleaning tank 50 and the first cleaning tank 20. By each of the The backstop unit 40 allows water to enter the second cleaning tank 50 from the inlet tank 10 in one direction, and then enter the first cleaning tank 20 from the second cleaning tank 50 .

The new system provides a method for cleaning at least one printed circuit board. The printed circuit board is rinsed or soaked in the water in the first cleaning tank 20 and the water inlet 10 for a predetermined time in sequence, or the printed circuit board is washed or soaked in the first cleaning tank in sequence. 20. The water in the second cleaning tank 50 and the water inlet 10 is rinsed or soaked for a predetermined time, so that the impurities and dirt on the printed circuit board fall off and enter the water. Since the impurities and dirt in the water will increase the resistance of the water, when the water When the resistance value is greater than the predetermined resistance value, the control unit 30 sends a signal to activate the drain valve 23 to drain the water, and then activates the water inlet valve 111 to input water, so that when the resistance value of the water is lower than the predetermined resistance value, the valve is closed. Water inlet valve 111.

Since the water flows from the water inlet 10 to the second cleaning tank 50 and the first cleaning tank 20 sequentially, the printed circuit board passes from the first cleaning tank 20 through the second cleaning tank 50 in the opposite direction. and reaches the water inlet 10, therefore no matter whether the printed circuit board is located in the water inlet 10, the second cleaning tank 50 or the first cleaning tank 20, the resistance value of the water can be kept lower than the predetermined resistance value, and the water can be kept clean. Clean the printed circuit board with water.

In other words, when the water quality of the first cleaning tank 20 is too poor, the water inlet valve 111 is opened. When the water quality of the first cleaning tank 20 is too poor, it represents an early indication that the printed circuit board is too dirty, which indicates that a large amount of cleaning is needed. Only when water enters the first cleaning tank 20 can the cleaning purpose be completed.

Please refer to the fourth figure. A transport unit 60 is provided on the top of the water inlet 10 and the first cleaning tank 20, or on the top of the water inlet 10, the second cleaning tank 50 and the first cleaning tank 20. The transport unit 60 is a mesh belt conveying device.

The conveying unit 60 has an inlet 61 and an outlet 62. The inlet 61 is provided for placing the printed circuit boards, and the conveying unit 60 transports the printed circuit boards to the first cleaning tank 20 in sequence. and above the water inlet tank 10, or above the water inlet tank 10, the second cleaning tank 50 and the first cleaning tank 20, and rinse the printing with the water from the first cleaning tank 20 and the water inlet tank 10 in sequence The circuit board, or the inlet tank 10, the second cleaning tank 50 and the first cleaning tank 20 rinse the printed circuit board, and the rinsed water flows into the first cleaning tank 20 and the inlet tank 10 respectively, or the The water inlet 10 , the second cleaning tank 50 and the first cleaning tank 20 .

When the resistance of the water is greater than the predetermined resistance, the control unit 30 sends a signal to activate the drain valve 23 to drain the water, and then activates the water inlet valve 111 to input water so that the resistance of the water is lower than the predetermined resistance. When the water inlet valve 111 is closed, the printed circuit board is transported to the outlet 62 for output by the transport unit 60 after cleaning.

The advantage of this new model is that the water quality of the first cleaning tank 20 corresponding to the material inlet 61 is dirtier than the water inlet 10 during use. At the same time, if the incoming material is dirty, the water quality of the first cleaning tank 20 of the material inlet 61 will be dirty. According to preliminary testing, the water quality of the first cleaning tank 20 can best reflect the dirt of the incoming material (the printed circuit board).

What the present invention detects is the early reaction of the first cleaning tank 20 at the feed inlet. If the feed material is dirty, it will directly react in the first cleaning tank 20 at the feed inlet 61. If it is detected that the first cleaning tank 20 is dirty, Dirty is the early reaction of dirty input materials, so it can respond faster than previous technologies.
