[0001] The invention relates to the technical field of electronic-grade pneumatic pumps, in particular to an electronic-grade pneumatic pump quick assembly workbench and a use method thereof. Background Art
[0002] Electronic-grade pneumatic pump is a specially designed pneumatic pump that uses compressed air as a power source and creates volume changes through the reciprocating deformation of the diaphragm, thereby achieving fluid suction and discharge. It is mainly used in high-tech electronics industries and in situations where highly corrosive media need to be handled. This type of pump is usually made of all-plastic material to adapt to special working environments such as high pollution, high risk, strong acidic liquids, low noise and clean rooms; The electronic-grade pneumatic pump quick assembly workbench is a device specially used for pneumatic pump assembly and use. It can stably clamp the pump body and its components, and is equipped with a shock-absorbing device to effectively absorb the vibration and impact generated by the pneumatic pump during operation and debugging, avoiding equipment failure caused by vibration; The shock absorbing device in the electronic-grade pneumatic pump quick assembly workbench is in a highly corrosive medium environment for a long time, and the inside of the shock absorbing device will inevitably be invaded by corrosive liquids. These corrosive liquids adhere to the shock absorbing device and cause the shock absorbing device to rust. Since the rust will reduce the seismic performance of the shock absorbing structure, the vibration generated during the operation and debugging of the electronic-grade pneumatic pump cannot be effectively absorbed, which increases the risk of damage to the electronic-grade pneumatic pump.

[0013] As a further optimized content of the present invention, the following steps are included: S1: Positioning the support frame assembly: Install the threaded damping rod into the threaded hole, and control the height of the support frame assembly by screwing the fixing nut to adjust the height of the support assembly in the vertical direction; S2: Installation and adjustment of shock-absorbing components: Then pass the cleaning component through the inter-plate hole and install it inside the support plate.

At the same time, the vibration generated between the components can shake off the corrosive substances attached to the surface of the shock-absorbing component, thereby reducing the possibility of rust and extending its service life, and preventing the pump body from being damaged due to the reduction in the shock-absorbing performance of the shock-absorbing component. The corrosive substances shaken off will be adsorbed in time, which not only achieves effective cleaning of the corrosive substances, but also avoids further erosion of the equipment by the corrosive substances. The cleanliness of the device can be maintained by regularly replacing the adsorption components, thereby extending the service life of the entire workbench. BRIEF DESCRIPTION OF THE DRAWINGS
