AI Technical Summary

Technical Problem

The bakelite threads on the heat sealing knife are prone to stripping, causing the heat sealing knife to wobble during descent, affecting the sealing quality and leading to product scrap. Existing methods of applying screw glue and replacing the bakelite knife holder are inconvenient and have low production efficiency.

Method used

A heat sealing knife fixing mechanism is designed, including a knife holder, a heat sealing knife, a fixing component, and a slider. By setting a limiting groove on the knife holder and cooperating with the slider, the rotation and movement of the nut are restricted, ensuring that the nut is always located in the limiting groove to avoid thread stripping. The slider is fixedly connected to the knife holder to achieve stable movement.

Benefits of technology

It effectively prevents the heat sealing knife from shaking, improves production efficiency, simplifies the disassembly and assembly process, and avoids sealing defects caused by stripped threads.

Description

TECHNICAL FIELD

[0001] The utility model relates to processing equipment technical field especially relates to a hot sealing knife fixing mechanism. BACKGROUND

[0002] In semiconductor packaging technology, the semiconductor is usually packaged by using a hot sealing knife and a glue bag, and after the semiconductor packaging is completed, the quality of the packaging is inspected, and some packages may have a serious bulging phenomenon, which is caused by slight shaking of the hot sealing knife during its descending process.

[0003] The slight shaking of the hot sealing knife during its descending process is caused by the fact that the bakelite thread for fixing the hot sealing knife is prone to thread slipping, and after the thread slips, the hot sealing knife shakes forward and backward, which leads to the scrapping of the packaged bulging products. SUMMARY

[0004] To solve the problem of the thread slipping of the bakelite thread for fixing the hot sealing knife, the utility model provides a hot sealing knife fixing mechanism.

[0005] The utility model discloses the following technical scheme:

[0006] The utility model discloses a hot sealing knife fixing mechanism which comprises a knife seat, a hot sealing knife, a fixing piece and a sliding block. The knife seat is provided with a fitting surface on one side. The first mounting hole is provided with a limiting groove near the fitting surface. The hot sealing knife comprises a screw and a nut. The nut is placed in the limiting groove and matches the size of the limiting groove. The screw is fixedly connected with the nut through the first mounting hole. The sliding block is fixedly connected with the fitting surface in close contact. The nut is always located in the limiting groove.

[0007] Further, the knife seat is further provided with a second mounting hole. The sliding block is fixedly connected with the knife seat through the second mounting hole.

[0008] Further, the knife seat is made of stainless steel or bakelite.

[0009] The utility model has the advantages of the following:

[0010] The hot sealing knife fixing mechanism limits the nut through the limiting groove and cooperates with the sliding block to resist the nut. The limiting groove and the sliding block resist and limit the movement of the nut. After the screw of the hot sealing knife is fixed with the nut, the thread slipping of the bakelite thread does not occur, and the hot sealing knife does not shake. BRIEF DESCRIPTION OF DRAWINGS

[0011] Figure 1 The utility model discloses a hot sealing knife fixing mechanism's knife seat structure diagram for the utility model's realization, functional characteristics and advantages will be further explained in conjunction with the embodiment, reference to the drawing.

[0012] In the drawing: knife seat 1, first mounting hole 11, limit groove 111, second mounting hole 12, fit face 13.

[0013] The utility model discloses a hot sealing knife fixing mechanism's knife seat structure diagram for the utility model's realization, functional characteristics and advantages will be further explained in conjunction with the embodiment, reference to the drawing. Specific implementation

[0014] In order to more clearly complete the technical scheme of the utility model, the utility model will be further explained in conjunction with the drawing below.

[0015] Please refer to Figure 1 The utility model discloses a hot sealing knife fixing mechanism including knife seat 1, hot sealing knife, fixing piece and sliding block, one side of knife seat 1 is provided with fit face 13, and first mounting hole 11 is arranged on knife seat 1, and limit groove 111 is arranged in first mounting hole 11 close to one side of fit face 13, and hot sealing knife includes screw and nut, and nut is placed in limit groove 111 and is matched with limit groove 111 in size, and screw is fixedly connected with nut by passing through first mounting hole 11, and sliding block is fixedly connected with fit face 13 closely, and make the nut always be located in limit groove 111.

[0016] In the embodiment:
