Description

Technical Field

[0002] At present, the cylinder head and cylinder block of automobile engines are fixedly connected by long bolts, and each engine requires screws. The long bolts come with gaskets, so that they can fit smoothly into the sleeve and be screwed in smoothly during the subsequent automatic tightening. Each time the bolts are cast, it is necessary to check whether the gasket fits the screw head. In the current production process, the screws are manually taken out of the box one by one and placed in the mounting holes of the engine cylinder head. For bolts whose gaskets do not fit the screw heads, it is necessary to press the screws into the holes with force to fit the gaskets to the screw heads.

[0003] At present, this process has the following problems: a large number of screws are required, and the screws are manually picked up and placed. There are many actions each time, which takes up a lot of time and has low efficiency.

[0004] At the same time, due to the rise of the concept of Industry 4.0, the requirements for automation of the automotive industry production line are getting higher and higher. It is necessary to develop a system to optimize and improve the above process flow, improve production efficiency and automation level, and design an automatic mechanism that can separate the screws at equal distances, cut the gasket to fit the screw head, and facilitate subsequent automatic material removal. Summary of the invention

[0005] In order to overcome the above-mentioned deficiencies, the purpose of the utility model is to provide an automatic feeding mechanism for long bolts with gaskets, which has strong applicability and can arrange the required screws at equal distances and send them out at one time without the need for manual picking up one by one; during the screw conveying process, the gasket always fits the screw head, and no manual inspection is required, thereby improving efficiency, solving the problems of low automation and low production efficiency in manual screw removal under the existing technology, while ensuring that the gasket fits the screw head.

[0027] In this embodiment, in order to smoothly remove the long screw, the relative positions of the detection switch 32, the adsorption magnet 33, the screw limiting groove 61, and the lifting rod 312 are on the same axis.
