Automotive lighting lamp cover embedding device

Abstract

The invention discloses an automotive lighting lamp cover embedding device. The outer side of a thermal buried cylinder is equipped with a vertical feeding mechanism capable of automatically supplying bolts, and the bottom of a chuck is respectively connected with a proximity sensor and a temperature sensor; the temperature sensor is connected with a servo motor for cutting off current. The reverse installation of the bolts is effectively prevented by the proximity sensor, the embedding temperature is effectively controlled by the temperature sensor, the embedding stability and the product quality are effectively improved, and the quality cost is reduced; meanwhile, the service life of the device is prolonged by current protection, the device safety is improved, the quick changeover of the thermal embedding machine is realized, the changeover time is shortened, and the changeover difficulty is reduced.

Description

technical field [0001] The invention relates to a production equipment of a screw thermal embedding machine, in particular to an embedding device for lamp covers of automobile lighting lamps. Background technique [0002] It is generally suitable for the assembly of car lights. Whether it is headlights or reversing lights, etc., the process of embedding screws is manual, which is not only time-consuming and laborious, but also not suitable for mass production of car lights, which affects the quality of car lights. Productivity. The existing hot embedding machine is especially suitable for screw embedding and hot riveting, hot melt embedding of nuts and plastic parts, and hot welding of metal parts and plastic parts; there is no trace of the surface of the workpiece after welding. However, in the existing thermal embedding machine, the bolts are conveyed to the bolt suction head through the chuck, but in the actual process, the bolts are conveyed wrongly up and down during t...

AI Technical Summary

Problems solved by technology

However, in the existing thermal embedding machine, the bolts are conveyed to the bolt suction head through the chuck, but in the actual process, the bolts are conveyed wrongly up and down during the feeding process, causing the chuck to clamp the wrong bolts. There is no error correction and alarm function, which reduces the production efficiency

Secondly, the bolt heating uses a high-current transformer to short-circuit it instantaneously to heat the bolt to the moving temperature. Such a temperature is often uncontrollable, and overheating will occur, resulting in the melting of the lamp part during the thermal embedding process.

Finally, the mold placed on the bottom plate of the tooling will be displaced during the thermal embedding process, so that the bolts cannot be in a fixed position during thermal embedding.

Because the position of each bolt on the lamp is inconsistent, which affects the uniformity of the product

[0003] Finally, the collet in the existing thermal embedding machine is fixed. When the mold is replaced, different bolts need to be used, and the fixed collet cannot meet the needs of molds with multiple specifications.
