The second air filter chamber 160 includes, but is not limited to, an air intake assembly 161 and an exhaust assembly 162 . In this embodiment, the air inlet assembly 161 is disposed on the side wall of the second air filter chamber 160 , and the exhaust assembly 162 is disposed on the bottom of the second air filter chamber 160 . In the second air filter chamber 160, the air inlet assembly 161 has a built-in air filter element to ensure that the air entering the second air filter chamber 160 is clean (does not contain dust, foreign matter, etc.); the second air filter element in the exhaust assembly 162 The filter 1622 absorbs dust pollutants inside the second air filter chamber 160, and the gas is discharged from the second exhaust hole 1621. This prevents dust contaminants from entering the glue coating 230 and reduces pits and bubbles generated on the surface of the glue coating 230 . Alternatively, the first air filter chamber 120 and the second air filter chamber 160 may share a filter screen and an exhaust hole.

Optionally, the user can select the model of the second air filter chamber 160 as needed. In a specific embodiment, the second air filter chamber 160 is selected based on: Among them, the volume of the equipment cavity is v, the initial dust quantity Q1 (10,000-level clean room, Q1=29300), the number of dust particles when the equipment is working normally is Qn (1,000-level clean room, Qn=2930), and n is the vacuum pump Equivalent pumping times. Determine the air pump model and cavity size by comprehensively considering the air pumping volume and air pumping time.

This application uses the coating device 130 before applying glue to the product to be glued. The plasma cleaning head 112 cleans the product to be glued, which increases the roughness of the surface of the product to be glued and enhances the friction of the glue on the surface of the product. Make the friction force greater than the surface tension of the glue itself, thereby reducing the movement of the glue and reducing the number of pits and bubbles on the surface of the glue.

The above are only some embodiments of the present application, and do not limit the scope of protection of the present application. Any equivalent device or equivalent process transformation made using the description and drawings of the present application, or directly or indirectly used in other related The technical fields are all equally included in the scope of patent protection of this application.
