An automatic assembly process for a seat belt retractor

Abstract

The invention relates to an automatic assembling technology for a safety belt rolling device. The assembling technology includes the following steps that S1, a feeding step of a rolling device body isconducted; S2, an assembling step of a ratchet wheel structure is conducted; S3, a pressing step of the ratchet wheel structure is conducted; S4, a transfer step of the rolling device body and the ratchet wheel structure is conducted; S5, an assembling step of an upper shell is conducted; S6, an assembling step of a dabber main wheel is conducted; S7, a feeding step of double products is conducted; S8, an assembling step of a driven gear and a drive gear is conducted; S9, an assembling step of a main gear is conducted; S10, an assembling step of a ring-shaped gear and a transition wheel is conducted; S11, a pressing assembling step of an end cover is conducted; and S12, a discharging step of finished products is conducted. By means of the automatic assembling technology for the safety belt rolling device, the automatic assembling operation of the finished safety belt rolling device is achieved, manual assembling is reduced, inferior-quality products are removed in time, the inferior-quality products are prevented from entering the market, the assembling quality and efficiency of the safety belt rolling device are improved, huge demands of the market are met, and good market application value is achieved.

Description

technical field [0001] The invention relates to the technical field of retractor assembly technology, in particular to an automatic assembly technology of a safety belt retractor. Background technique [0002] At this stage, society is developing rapidly, people's living standards have been greatly improved, and people are paying more and more attention to the quality of life. Among them, cars are the most important means of transportation in life. The sales of cars are increasing, and the demand for their main parts is also increasing. ; Such as the retractor of the car seat belt, the function of the retractor is to store the webbing and lock the webbing to pull out, it is the most complicated mechanical part in the seat belt. There is a ratchet mechanism inside the retractor. Under normal circumstances, the occupant can pull the webbing freely and at a constant speed on the seat, but once the continuous pulling process of the webbing from the retractor stops or when the ve...

AI Technical Summary

Problems solved by technology

There is a ratchet mechanism inside the retractor. Under normal circumstances, the occupant can pull the webbing freely and at a constant speed on the seat, but once the continuous pulling process of the webbing from the retractor stops or when the vehicle encounters an emergency, the ratchet mechanism will work. The locking action will automatically lock the webbing to prevent the webbing from being pulled out; the retractor mainly includes the main body of the accessory retractor, the ratchet structure, the upper shell, the mandrel main wheel, the slave gear, the transmission gear, the main gear, the ring gear, and the transition wheel and end caps; at present, the existing safety belt retractor assembly process is cumbersome, mainly through manual assembly and splicing, however, due to the small size of the retractor parts and the high reliability of the connection , When manually assembling the retractor, it is necessary to use tools (tweezers, needle-nose pliers, etc.) to spend a lot of time picking up parts, aligning parts, and installing parts. The manual assembly process leads to low efficiency, high cost, and low quality
