Pipeline valve protection device for high-density interconnect circuit board production

Abstract

The invention relates to a pipeline valve protection device for production of high-density interconnection circuit boards. The pipeline valve protection device comprises an upper sleeve body and an arc elastic board, wherein a handle of a valve is embedded inside the upper sleeve body in a limited mode, the arc elastic board is manufactured integrally on one end face of the upper sleeve body, and the arc elastic board is wound round and connected with the outer edge of the valve under the handle in a pressing mode and is matched with the upper sleeve body to position the handle. After the pipeline valve protection device is installed, the upper sleeve body and the arc elastic board can not be twisted from side to side, the correct state of the handle of the valve is guaranteed, a chain is installed between the front end of the upper sleeve body and the upturned end of the arc elastic board in a penetrating mode, and then the chain is fixed through a lock, so that the whole device can not fall out of the valve, and the safety of the valve is further improved.

Description

technical field [0001] The invention belongs to the field of valve protection equipment in the production of high-density interconnected circuit boards, in particular to a pipeline valve protection device for high-density interconnected circuit board production. Background technique [0002] In the production of high-density interconnected circuit boards, pipelines are needed in many processes. These pipelines are responsible for transporting various liquid medicines. These liquid medicines are continuously circulated according to production requirements to ensure the normal production of circuit boards. In the actual production process, due to the unfamiliarity of the operator's business, misoperation of the valve often occurs. In order to avoid the above-mentioned problems when the product is scrapped or the equipment is damaged, people usually put a label on the valve or lock it with a chain lock.

Problems solved by technology

In the actual production process, due to the unfamiliarity of the operator's business, misoperation of the valve often occurs. In order to avoid the above-mentioned problems when the product is scrapped or the equipment is damaged, people usually put a label on the valve or lock it with a chain lock. However, after long-term use, the font or pattern on the label is blurred and difficult to identify, and After the chain lock is locked, the valve can still be operated because the chain has a certain length. It can be seen that the above two methods do not realize the protection of the state of the pipeline valve.
