Automatic press-fitting system for safety helmet top belt and helmet hoop ring belt

Abstract

The invention particularly relates to an automatic press-fitting system for a safety helmet top belt and a helmet hoop ring belt. The system comprises a top belt positioning device, a top belt grabbing device and an annular belt positioning device, the top belt positioning device is used for taking out the safety helmet top belt on the conveying unit and positioning the safety helmet top belt, theannular belt positioning device is used for positioning the helmet hoop annular belt, the top belt grabbing device grabs the positioned safety helmet top belt, moves the positioned safety helmet topbelt to the positioned helmet hoop annular belt and tightly presses the safety helmet top belt and the positioned helmet hoop annular belt, and the annular belt positioning device adjusts the postureof the helmet hoop annular belt. The safety helmet top belt and the annular belt are both thin plastic parts and are not easy to grab, the top belt positioning device and the annular belt positioningdevice are used for positioning the safety helmet top belt and the annular belt respectively, and the top belt grabbing device is used for grabbing the top belt to the proper position of the annular belt and then pressing the top belt. Meanwhile, the posture of the helmet hoop ring belt is adjusted through the girdle positioning device in the crimping process, so that four-point pressing can be realized, the system is simple in structure, automation can be realized, and the labor cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of automatic processing of safety helmets, in particular to an automatic press-fitting system for a top belt and a ring belt of a safety helmet. Background technique [0002] A safety helmet refers to a hat that protects the human head from injuries caused by falling objects and other specific factors. It generally consists of three parts: a hat shell, a hat lining and a chin strap. Cap shell: This is the main part of the safety helmet. It generally adopts an elliptical or hemispherical thin shell structure. This structure will produce a certain pressure deformation under the impact pressure. Due to the rigidity of the material, it absorbs and disperses the force, plus The smooth surface and circular curve can easily make the impact object slip away, and reduce the impact time, which can effectively protect the user's head safety. According to the need to strengthen the strength of the shell of the helmet, ...

Problems solved by technology

[0003] figure 1 Shown is the helmet top strap commonly used in existing helmets, which includes two buckles made of plastic parts, and the two buckles are connected by nylon straps; figure 2 What is shown is the helmet hoop belt commonly used in the existing helmets. Many details are omitted in the figure, and the parts related to this application are reserved. In the production of helmets, the helmets are currently made manually. The top strap is clamped on the hat hoop ring. In order to improve production efficiency and speed, it is urgent to develop a system that can realize the automatic assembly of the two, but there are many problems to be solved: First, the safety hat top strap and the hat hoop ring The straps are all flakes, and the two buckles of the top strap are still connected by nylon straps. The two are relatively soft and difficult to locate; Three top bands are cross-shaped, which makes automatic assembly difficult; third, in order to effectively protect, when the hat hoop band is unfolded, the distance between the two fixed points of the same top band on the hat hoop band must be If the distance is greater than the actual fixed point on the top strap, during manual assembly, after the same top strap is fixed, the hoop ring will be deformed. Manual installation can ignore these odd shapes, but automatic assembly becomes a difficulty

Based on the above difficulties, there is no similar automatic assembly device
