Abstract
Description
Technical Field
[0001] The utility model relates to the field of waste liquid collection, in particular to a pipeline blocking prevention device for automatic waste discharge. Background Art
[0002] During wafer coating, the wafer coater uses a chemical solution to clean the wafer backside during coating to prevent contamination. After coating, a side wash is performed to remove photoresist from the wafer edge using chemical solution to facilitate subsequent processing. This process generates waste liquid due to the use of chemical solution. This waste liquid can be mixed with some photoresist. Direct discharge of this waste liquid over time can cause clogging of the discharge pipes due to the accumulated photoresist. Therefore, direct discharge from the factory side is not feasible.
[0003] The existing waste liquid discharge method is to place a waste liquid barrel inside the machine. The waste liquid first flows into the waste liquid barrel for collection. When the appropriate liquid level is collected, the operator will replace the waste liquid barrel. Although there will be no leakage, there are other problems during use. For example, cleaning is relatively frequent, and waste liquid and photoresist will accumulate together in the container. Although photoresist only occupies a very small part of the container, when there is too much waste liquid, the container still needs to be replaced. During the replacement process, the machine will be unable to produce, reducing the machine utilization rate. In order to solve the above problems, we propose an automatic waste discharge anti-blocking pipeline device. Utility Model Content
[0004] The utility model aims to provide a pipeline device for automatically discharging waste to prevent clogging, which solves the problems that the existing pipeline device has poor collection effect and frequent cleaning.
[0005] The above technical objectives of the present utility model are achieved through the following technical solutions: a device for preventing pipeline blockage during automatic waste discharge, comprising a base plate, a fixed frame is provided on the top of the base plate, a support plate is bolted between the base plate and the fixed frame, a machine waste liquid pipeline is provided through the top of the fixed frame, a three-way pipe is fixedly connected to the bottom end of the machine waste liquid pipeline, and the other two ends of the three-way pipe are fixedly connected to connecting pipelines, a valve is installed on the surface of the connecting pipeline, a fixing seat is symmetrically installed on the bottom of the fixed frame, the internal thread of the fixing seat is connected to a collection tank, and the surface of the collection tank is penetrated by an overflow drainage pipeline.
[0006] The adoption of the above technical solution can improve the device's collection and separation effect on waste liquid, reduce the burden of frequent cleaning for personnel, and enable cleaning without stopping the machine by switching the flow direction, thereby improving the utilization rate of the machine and being highly practical.
[0007] The utility model is further configured as follows: a fixing plate is fixedly sleeved on the surface of the machine waste liquid pipeline and the connecting pipeline, and the bottom of the fixing plate is bolted to the fixing frame.
[0008] By adopting the above technical solution, the waste liquid pipeline and the connecting pipeline of the machine can be fixed by setting the fixing plate, thereby improving the stability of the waste liquid pipeline and the connecting pipeline of the machine during the drainage process.
[0009] The utility model is further configured as follows: a non-slip pad is bonded to the bottom of the bottom plate.
[0010] By adopting the above technical solution and providing the anti-skid pad, the friction force of the bottom of the base plate when it is temporarily placed can be increased, thereby playing an anti-skid role.
[0011] The utility model is further configured as follows: two mounting holes are provided on the top of the base plate.
[0012] By adopting the above technical solution, the setting of the mounting holes can facilitate personnel to fix the device to the equipment platform with screws.
[0013] The utility model is further configured such that: the distance between the bottom of the collection tank and the bottom plate is greater than the height of the fixing seat.
[0014] By adopting the above technical solution, the reserved space below the collection tank can be sufficient for removing the collection tank.
[0015] The utility model is further configured as follows: the surfaces of the bottom plate, the support plate and the fixing frame are all coated with anti-corrosion paint.
[0016] By adopting the above technical solution and providing the anti-corrosion coating, the anti-corrosion and moisture-proof effects of the surfaces of the bottom plate, the support plate and the fixing frame can be improved.
[0017] The utility model is further configured as follows: the collection tank is made of a transparent material.
[0018] The above technical solution can facilitate personnel to observe the internal deposited photoresist.
[0019] In summary, the present invention has the following beneficial effects:
[0020] The utility model fixes the bottom plate to the specified position first, and fixes the bottom end of the machine waste liquid pipeline to the tee pipe after the bottom plate is fixed. After the machine waste liquid pipeline is fixed, the valve on the left connecting pipeline is opened to allow the waste liquid and photoresist to enter the collection tank on the left. The heavier photoresist will settle at the bottom, and the waste liquid will flow into a larger container prepared separately through the overflow drainage pipeline after rising. When there is too much precipitated photoresist in the left collection tank, the left valve is closed and the right valve is opened, so that the waste liquid can change its flow direction and enter the right collection tank. Finally, the left collection tank can be removed for cleaning. This can improve the collection and separation effect of the device on waste liquid, reduce the burden of frequent cleaning on personnel, and can achieve cleaning without stopping the machine by switching the flow direction, thereby improving the utilization rate of the machine and having high practicality.
