AI Technical Summary

Technical Problem

Existing cleaning tools can only clean one exhaust duct at a time, requiring operators to repeatedly locate and operate multiple times, resulting in low cleaning efficiency.

Method used

Design a cleaning tool that includes multiple cleaning heads, which are spaced apart along the length of the mounting plate. The spacing between adjacent heads is adapted to the spacing of the mold venting grooves. The tool achieves simultaneous cleaning of multiple venting grooves through reciprocating scraping motion. The stability and easy replacement of the cleaning heads are ensured by the mounting plate, connecting bolts, retaining rings, and magnet structure.

Benefits of technology

It enables simultaneous cleaning of multiple exhaust channels, improving cleaning efficiency, avoiding repeated positioning and multiple operations, and ensuring the stability and convenience of the cleaning process.

Claims

1. A cleaning tool for a vent slot of a semiconductor plastic encapsulation mold, comprising a cleaning head (1) for cleaning residues in the vent slot, characterized in that, It also includes a mounting plate (2) with a long strip structure, one end of which is fixedly connected to a mounting handle (3). There are multiple cleaning heads (1), which are arranged at intervals along the length of the mounting plate (2) and fixedly connected to the mounting plate (2). The spacing between two adjacent cleaning heads (1) is adapted to the spacing between two adjacent venting grooves on the semiconductor molding die.

2. The cleaning tool of claim 1, wherein, The mounting handle (3) includes a baffle (302) with a plate-like structure. A handle (301) is vertically fixed on one side of the baffle (302), and a connecting plate (303) for connecting the mounting plate (2) is vertically fixed on the other side of the baffle (302). One end of the mounting plate (2) is fixedly connected to the connecting plate (303) by a connecting bolt (4).

3. The cleaning tool of claim 2, wherein, One end of the mounting plate (2) is provided with a countersunk hole for accommodating the head of the connecting bolt (4). The connecting bolt (4) is an internal hex bolt. The connecting bolt (4) passes through the mounting plate (2) and the connecting plate (303) from bottom to top and is then fixedly connected to the nut (5). The bolt head of the connecting bolt (4) is located in the countersunk hole.

4. The cleaning tool of claim 1, wherein, The cleaning head (1) includes a large end (101) for cleaning residue and a small end (102) for connecting to the mounting plate (2). The large end (101) is cylindrical and the diameter of the large end (101) is consistent with the width of the venting groove of the semiconductor molding die. The small end (102) is fixedly connected to the mounting plate (2).

5. The cleaning tool of claim 4, wherein, The mounting plate (2) is provided with a plurality of circular holes (201) for installing the cleaning head (1). The diameter of the circular holes (201) is adapted to the outer diameter of the small end (102). The outer periphery of the small end (102) is provided with an annular groove. A retaining ring (6) for axially limiting the cleaning head (1) is installed in the groove. The outer diameter of the retaining ring (6) is larger than the diameter of the circular holes (201).

6. The cleaning tool of claim 5, wherein, The distance from the upper surface of the large end (101) to the slot is the same as the depth of the circular hole (201).

7. The cleaning tool of claim 6, wherein, The upper end face of the large end (101) is fixed with a magnet (7) for enhancing connection stability, and the magnet (7) can be attracted to the lower plate face of the mounting plate (2).
