Description

Slide rail unloading device and unloading method thereof

technical field

The invention relates to a slide rail unloading device and a material unloading method thereof, which is especially suitable for processing and unloading slide rails of automobile seats, and belongs to the field of automobile parts processing.

Background technique

Conveying machinery is a mechanical device that transports or conveys bulk materials and finished items along a certain route in a continuous, uniform, and stable manner. Since the conveying machinery can continuously carry materials in a range, the operating cost is low and the efficiency is low. High, easy to control and other characteristics, so it is widely used in industrial production. It is one of the basic equipment for material transportation and handling in industrial production. All kinds of automatic assembly lines used in modern production enterprises belong to automatic conveying machinery.

With the rapid development of my country's industrialization, my country's automobile manufacturing industry has also made great progress. However, in the production and assembly process of auto parts in our country, there is still no automatic process for the processing of many products.

Specifically, a slide rail at the bottom of a car seat is composed of two parts, an upper rail and a lower rail. It needs to be sent to the processing station together for subsequent combined installation. In the current processing and production process, most enterprises still use manual handling to unload and transport the upper and lower rails. In this way, it not only takes up a large amount of labor force of the production enterprise, but also the whole handling process is arduous and the handling efficiency is low, and even a little carelessness will scratch the workpiece and cause parts to be scrapped.

However, some enterprises that adopt mechanized unloading operations face other problems. Wherein the most important problem is that the currently widely used belt-type conveying device still needs to occupy a large amount of labor in its conveying process. The traditional conveyor belt machine adopts single-line transmission, and has a single structure, and does not have the function of picking up materials from the previous process equipment, so it needs manual loading operations. However, when the workpiece is delivered to the end of the conveyor belt machine, the operator still needs to collect it manually.

CN103552833A discloses an automatic unloading collection conveyor belt machine, which includes a conveyor belt body, a discharge device, and a material collection device. Driving rollers are provided at both ends of the conveyor belt body, that is, the first driving roller and the second driving roller. rollers, the first driving roller and the second driving roller are connected with conveyor belts, and the unloading device includes an unloading frame and an unloading transmission roller, and the unloading transmission roller is installed on the unloading In the material rack, one end of the unloading rack is connected to the second driving roller, and the other end of the unloading rack is connected to the collecting device.

Although this invention realizes the transportation and collection of workpieces, there is a very serious problem in its application process, that is, it is impossible to distinguish different workpieces during the transportation process. Specifically, if the invention is used for all The conveying of above-mentioned upper rail and lower rail is easy to make described upper rail and lower rail get mixed up in conveying process because of the blindness of its conveyer belt conveying. In this way, not only is it not conducive to the subsequent assembly of the workpieces, but also if the mixed workpieces are to be separated, it will take up a lot of labor for the production enterprise.
