Description

Technical Field

[0001] The utility model relates to the manufacture of igniters, and particularly to an assembly device for the lead glue caps of igniters. Background Art

[0002] Currently in the industry, for the assembly of the lead glue caps of igniters, it is carried out manually or by a mechanical structure. Two inserts are inserted and the assembly ends of the glue caps are expanded to both sides to form a channel for the insertion of the terminal parts of the igniter leads. Then, the terminal parts of the igniter leads are inserted into the glue caps through the channel, and finally the two inserts are withdrawn. This method is difficult to handle the assembly of glue caps with special shapes (such as L-shaped). Either the formed channel cannot allow the terminal parts of the igniter leads to be inserted in place and will get stuck in the channel, or the glue caps will be damaged when the channel is formed. Content of the Utility Model

[0003] To solve the above problems, the utility model proposes an assembly device for the lead glue caps of igniters, which can realize the semi-automatic assembly of L-shaped glue caps and leads (manual loading and unloading).

[0004] The technical solution of the utility model:

[0005] An assembly device for the lead glue caps of igniters is used for assembling L-shaped glue caps and leads. One end of the L-shaped glue cap is the assembly end, and one end of the lead is the terminal part, which is matched with the L-shaped glue cap. The assembly device includes a base and two inserts arranged side by side. A contour groove is provided on the base, and the contour groove is matched with the L-shaped glue cap lying on its side, and one end of it is open. The L-shaped glue cap lying on its side is placed in the contour groove on the base, and its assembly end extends out by a section from the opening. The two inserts are inserted and the assembly ends of the L-shaped glue cap lying on its side are expanded to both sides to form a channel between the two inserts. The terminal part of the lead is inserted into the L-shaped glue cap lying on its side through the channel, and then the two inserts are withdrawn to complete the assembly of the L-shaped glue cap and the lead.

[0006] For the assembly of the L-shaped rubber cap and the lead wire, when using the traditional assembly device, the problems of "either the formed channel cannot allow the ignition lead wire terminal part to be inserted in place and will get stuck in the channel, or the rubber cap will be damaged when forming the channel" occurred. We conducted research and found that due to the structural limitations of the L-shaped rubber cap, there is a certain degree of shrinkage at its assembly end, which affects the expansion of the assembly end of the L-shaped rubber cap to both sides. The formed channel has a large opening and a small bottom. When expanding the assembly end of the L-shaped rubber cap to both sides, considering the mouth, the terminal part of the lead wire will get stuck, and considering the bottom, the assembly end of the L-shaped rubber cap will be damaged. And during the assembly process, if the two inserts are designed to be relatively wide, when inserted into the assembly opening of the L-shaped rubber cap, their upper and lower ends will rub against the inner wall of the assembly opening of the rubber cap, which will damage the assembly opening of the rubber cap. Coupled with the fact that the inserts are relatively thin, it will aggravate the damage to the assembly opening of the rubber cap. Based on this, we further optimized and designed on the traditional assembly method. The L-shaped rubber cap lies on its side, which reduces the shrinkage at the assembly end of the L-shaped rubber cap. The formed channel has a similar bottom difference. In addition, the width of the insert matches the height of the terminal part of the lead wire. The terminal part of the lead wire is inserted sideways, and its height is relatively smaller than when inserted straight. Therefore, the width of the insert is set to be smaller, and the terminal part of the lead wire can easily be inserted through the channel between the two inserts without getting stuck, and the insertion and expansion of the two inserts to both sides will not damage the assembly end of the L-shaped rubber cap.

[0007] The assembly device further includes a pressure rod, and the pressure rod is installed above the base; before the two inserts are inserted into and expand the assembly end of the L-shaped rubber cap lying on its side to both sides, the pressure rod presses on the L-shaped rubber cap lying on its side; to prevent the L-shaped rubber cap from shifting when the two inserts expand the assembly end of the L-shaped rubber cap lying on its side to both sides.

[0008] There is an opening on the side wall of the base, and the opening is directly opposite to and communicates with the other end of the contour groove; the assembly device further includes a pin rod; after the terminal part of the lead wire is inserted into the L-shaped rubber cap lying on its side through the channel, the pin rod is inserted into the contour groove through the opening, inserted into the L-shaped rubber cap lying on its side from the other end of the L-shaped rubber cap lying on its side and locks the terminal part of the lead wire; to prevent the terminal part of the lead wire from being pulled out when the two inserts are withdrawn;

[0009] When inserting, a relatively hard lead wire can be directly inserted, but a relatively soft lead wire cannot be easily inserted. For this reason, it is designed that the assembly device further includes a push rod; when the terminal part of the lead wire is inserted into the L-shaped rubber cap lying on its side through the channel, it is pushed by the push rod.

[0010] When the two inserts are withdrawn, if the two inserts are directly withdrawn, the two inserts expand the assembly end of the L-shaped rubber cap lying on its side to both sides, and there will be a tug-of-war with the L-shaped rubber cap lying on its side. For this reason, we designed that the two inserts move towards each other once, so that the distance between the two inserts is a, and a is greater than the size of the lead wire, slightly loosening the assembly end of the L-shaped rubber cap lying on its side and not clamping the lead wire. In this way, the two inserts can be smoothly withdrawn.

[0011] Two inserts are installed on the finger cylinder and are driven by the finger cylinder to open or close. When closed, the two inserts move towards each other;

[0012] When the two inserts open, they push open the assembly ends of the L-shaped rubber caps lying on their sides towards both sides;

[0013] A limit post is installed on the side of the finger cylinder. When it moves between the two fingers of the finger cylinder, it constitutes a limit for the two inserts to move towards each other at one time.

[0014] For the said insert, its end is a pointed head and a middle section is an arc-shaped depression; it is easier to insert into the assembly end of the L-shaped rubber cap lying on its side, and the effect of pushing open is good.

[0015] The said assembly device further includes a bracket. Brief Description of the Drawings
