Description

A vacuum cleaner shell fusion and cooling integrated hot riveting device and its application method

technical field

The invention relates to the technical field of vacuum cleaner shell riveting equipment, in particular to a vacuum cleaner shell fusion and cooling integrated thermal riveting device and an application method thereof.

technical background

The outer shell of the vacuum cleaner consists of a support shell and a surface-modified texture shell. During the riveting process, the plastic components are pre-fitted manually. Along with the alignment of the riveting points, manual operation is usually used during riveting, and the riveting points need to be corrected. Carry out riveting at a set temperature, and finally cool and form the riveting point.

In the hot riveting process of the existing car armrest cover, due to the small size of the car armrest cover, positioning is difficult, and secondary positioning is required during hot riveting, which also leads to hot riveting points when the cover is hot riveted The inaccurate position of the armrest caused the scrapping of the armrest cover. Ningbo Jifeng Auto Parts Co., Ltd. applied for "a hot riveting device for automobile armrest cover" on December 29, 2017, including: workbench, workpiece placement mechanism, workpiece fixing mechanism, and hot riveting mechanism. The advantage is that the hot riveting device for the cover plate of the automobile armrest only needs to place the workpiece in the placement groove, and the hot riveting mechanism can accurately rive the workpiece without secondary positioning, which improves the accuracy of the hot riveting of the workpiece. The scrap rate is greatly reduced, but due to the irregular shape of the armrest cover, only relying on two-axis directional clamping increases the displacement error of the riveting point, resulting in the problem that the force riveting is not firm. In the prior art, the riveting of products is usually done manually. Not only does it need to heat the product first, but it also needs to place the heated product at the riveting place for riveting. The labor intensity is high and the safety cannot be guaranteed. , and the delivery of the product is not guaranteed, once there is an operation error, it will easily lead to the phenomenon that the equipment cannot be used normally.

Shenzhen Xinyuan Education Consulting Co., Ltd. applied for "an automatic hot riveting equipment" (application publication number CN 108943749 A) on September 28, 2018, including workbench components, front part feeding, and hot riveting machine assembly. Efficient and high-quality production, saving labor, reducing finished products, and suitable for household appliances, car lights, automotive fuses and other fields, but in the riveting process, the positioning and clamping method of plastic assemblies needs to be further optimized. In the process of traditional automobile instrument panel pointer processing, multiple workpieces are assembled sequentially by machinery and hand, then pre-pressed and riveted, and finally the riveted state and hot stamping state of the product are manually inspected. This processing method results in high processing costs, error-prone manual participation, and product quality cannot be guaranteed.

Suzhou Runlu Automation Technology Co., Ltd. applied for "A Semi-automatic Assembly Hot Riveting Machine for Automotive Dashboard Pointers" (Application Publication No. CN 108406271 A) on April 27, 2018, including the first workbench and the second workbench arranged side by side. Taiwan, a fast manipulator mechanism, the first assembly mechanism, the second assembly mechanism and the third assembly mechanism, which realize the semi-automatic continuous processing of the pointer of the automobile dashboard, and only two operators can complete the workpiece assembly of the pointer of the automobile dashboard at one time , rectification, preloading, riveting, testing and discharging, which greatly improves the processing efficiency, but on the circumference of the surface of the installation turntable, the 8 pairs of assembly fixtures are set, which increases the complexity of the installation and positioning of the riveting components. In actual operation, the manual difficulty is increased.
