Problems solved by technology

[0004] Disadvantages of existing technology:
[0005]1. It will take a lot of time and energy to blow and wash the 1860 holes one by one. At the same time, the high-pressure airflow will also produce a very harsh sound. Staying in such an environment for a long time It will also affect the physical and mental health of cleaning staff
[0006]2. The high-pressure air flow cannot completely blow out the conductive adhesive in the hole. If there is conductive adhesive residue, it will affect the subsequent printing of conductive adhesive and even pollute the conductive adhesive

Embodiment 1

[0031] Such as figure 1 and figure 2 shown.

[0032] A punching type back contact component printing screen cleaning tool, including a base 1, a number of cleaning bristles 2 are arranged on the front of the base, and the cleaning bristles 2 include interconnected hard base supporting parts 22 and soft bristle ejectors. Part 21, the hard base supporting part 22 is connected with the front of the base.

[0033] According to the above structure, the present invention mainly designs a printing screen cleaning brush, which is specially used for cleaning the conductive adhesive printing screen of the MWT component, and cleans the conductive adhesive in the upper hole of the printing screen from the printing mesh. Generally, a printing screen only needs to be operated 60 times to clean the entire printing screen. Compared with the traditional purging method, 1860 purging operations are required, and the efficiency of the invention is greatly improved.

[0034] Generally, since ...

Embodiment 2

[0048] Compared with the embodiment: preferably, the length of the hard base supporting part 22 is 0.3 cm, and the length of the soft bristle ejecting part 21 is 0.2 cm.

Abstract

The invention discloses a cleaning tool for a punching-type back-contacting assembly printing screen. The cleaning tool for the punching-type back-contacting assembly printing screen comprises a base, wherein a plurality of cleaning bristles are arranged on the positive surface of the base. Each cleaning bristle comprises a hard base supporting part and a soft bristle ejection part, wherein the hard base supporting part is connected with the positive surface of the base. The cleaning tool for the punching-type back-contacting assembly printing screen is high in cleaning efficiency and good in cleaning effect.

Description

technical field [0001] The invention relates to printing screen cleaning equipment, in particular to a high-efficiency back contact component printing screen cleaning tool. Background technique [0002] As a new type of high power, zero packaging loss, and the promotion of mass production, MWT components will definitely become the development direction of high power components. The current MWT component manufacturing process is to use screen printing to evenly cover the conductive adhesive on the conductive backplane and ensure the height of the conductive adhesive. This method must ensure that the screen needs to be cleaned every 8 hours of printing, and the screen The cleaning of the upper 1860 printing holes is the biggest problem. [0003] At present, the cleaning method of the screen is: use a high-pressure air gun to blow and wash the 1860 holes on the screen one by one, use the air knife of the high-pressure air gun to blow the conductive glue in each hole out of th...
