Novel dry ice cleaning base and cleaning method thereof

Abstract

The invention discloses a novel dry ice cleaning base and a cleaning method thereof. The novel dry ice cleaning base comprises a vacuum cavity base, a vacuum base and a supporting base set, wherein the vacuum cavity base is provided with a vacuum cavity communicating with a vacuum section system; the vacuum base is in seal connection with the vacuum cavity; a plurality of bosses arranged at intervals are arranged on the side, away from the vacuum cavity, of the vacuum base in a protruding mode; the bosses are provided with through grooves communicating with the vacuum cavity in the extending directions of the bosses; the supporting base set comprises a plurality of supporting bases which can be replaceably mounted to the vacuum base; the supporting bases are provided with hollow pylons arranged on the outer sides of the bosses in a sleeving mode; the size of the hollow pylons in the axial direction of the pylons is greater than that of the bosses; and the surfaces of the sides, away from the vacuum base, of the hollow pylons are provided with supporting faces for supporting products. Rapid dismounting and mounting of an original supporting base are achieved, and the machine replacement time is shortened, and the whole steps are simple and easy to operate, labor input in the replacement process is reduced, and the machine utilization rate and production efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of dry ice cleaning, in particular to a novel dry ice cleaning base and a cleaning method thereof. Background technique [0002] In order to ensure the smooth progress of the packaging and improve the tightness and firmness of the connection between the plastic-encapsulated product and the circuit board, the plastic-encapsulated product needs to be cleaned by a dry ice cleaning machine. [0003] Due to the variety of existing electronic products, the types, shapes, and sizes of plastic-encapsulated products are different. Therefore, correspondingly, the support surfaces of the support seats used to support the product bases of the machine are also different. In order to improve dry ice cleaning The types of applicable products of the machine table can improve the machine utilization rate of the machine table. When the existing dry ice blasting machine table is replaced with the support seat used to support t...

[0003] Due to the variety of existing electronic products, the types, shapes, and sizes of the plastic-encapsulated products are different. Therefore, correspondingly, the support surfaces of the support seats used to support the product bases of the machine are also different. In order to improve dry ice cleaning The types of applicable products of the machine table can improve the machine utilization rate of the machine table. When the existing dry ice cleaning machine table is replaced with the support seat used to support the plastic sealing product, such as Figure 8 As shown, the required steps are: dismantling the hot air duct 101—removing the shell 102 of the support platform 103—removing the lifting platform 104 of the carrier—removing the heating rod 105—removing the nozzle base 106 in the cleaning area—installing the hot air pipe 101—installing The shell 102 of the supporting platform 103—the lifting platform 104 for installing the carrier—installing the heating rod 105—installing the new nozzle base 106 in the cleaning area, the whole process needs to be shut down, and the steps are cumbersome and complicated; and each replacement takes 5 hours Left and right, it is extremely time-consuming; since the whole process requires human participation, it is a waste of human labor; shutdown and replacement will also lead to low utilization of the machine
