Description

Technical Field

[0001] This utility model belongs to the technical field of workpiece riveting equipment, and in particular a rapid hot melt riveting device. Background Technology

[0002] Currently, in the workpiece manufacturing and processing industry, especially in the 3C industry, products with plastic components sometimes require the embedding of metal parts, such as thin metal sheets, to achieve localized conductivity or wear resistance. This necessitates riveting the metal parts onto the plastic parts. The product generally consists of three parts: the main body, the metal sheet, and the pin cap. Currently, the main body, metal sheet, and pin cap are mostly placed manually. This increases the possibility of human error, and due to the limitations of manual operation, the entire riveting process can be time-consuming, leading to low production efficiency. Furthermore, because the equipment is exposed to high temperatures for extended periods, manual operation by workers increases the risk of burns and raises safety hazards.

[0003] In addition, temperature control is another major challenge in traditional equipment. Many devices struggle to achieve precise temperature control during the hot-melting process, which not only affects the quality of riveting but may also damage the workpiece. Furthermore, due to design flaws, some devices are prone to positional deviations in the workpiece during processing, which increases both the scrap rate and production costs.

[0004] Therefore, there is an urgent need for a new type of device that can overcome these shortcomings in order to improve production efficiency, ensure product quality, and reduce production costs. Utility Model Content

Unless otherwise specified, the methods used in this invention are conventional methods in the field. The quantities of all substances used in this invention are conventional usage quantities. Structures and connections not described in detail in this invention can be understood as conventional technical means in the field.

[0034] A rapid hot melt riveting device, such as Figures 1 to 10As shown, the device includes a base 1, a workpiece clamp 2, a support column 3, a temperature controller 4, a pneumatic cylinder 5, a support platform 6, a hot melter 7, and a pneumatic guide rail 8. The base is connected to the support column and the pneumatic guide rail, the workpiece clamp is connected to the pneumatic guide rail, the support platform is connected to the support column, the hot melter is connected to the support platform, and the temperature controller and the pneumatic cylinder are both connected to the hot melter.

[0035] The pedestal is set horizontally, the support columns are set vertically, and the support columns are spaced several times in a circular direction. The bottom of the support columns are vertically connected to the pedestal, and the top of the support columns are vertically connected to the support platform. The support platform is set horizontally and is set on the pedestal by multiple support columns, so that the support platform can be raised to facilitate the installation and setting of subsequent structures, which is conducive to the miniaturization and integration of the device.

[0036] The pneumatic cylinder is vertically positioned and mounted on a support platform. Its drive shaft is fixedly connected to the heat melter. The pneumatic cylinder can drive the heat melter to move up and down vertically, allowing it to move downwards when heat melting is needed and upwards when not, facilitating subsequent operations. The heat melter is longitudinally positioned and can be used with the metal parts to be riveted (such as...). Figure 11 As shown, the hot melter is set up to match the base and the support platform. The hot melter can perform hot riveting operations between the metal parts and the plastic parts to be riveted.

[0037] The temperature controller is mounted on the support platform and is connected to the hot melt machine. The temperature controller can provide heat to the hot melt machine.

[0038] The pneumatic guide rail is arranged longitudinally and is located on the upper surface of the platform. One longitudinal side of the pneumatic guide rail is positioned directly below the hot melt machine. The workpiece clamp is slidably connected to the pneumatic guide rail. The pneumatic guide rail can drive the workpiece clamp to move back and forth longitudinally along the pneumatic guide rail. The workpiece clamp is positioned between the pneumatic guide rail and the hot melt machine, facilitating the hot melt machine to perform hot riveting operations on the metal parts to be riveted on the workpiece clamp.
