Abstract

The invention relates to a plastic hot riveting device for an automobile lamp. A workbench is provided with a lamp body positioning mechanism, a press riveting mechanism, a rivet head grabbing mechanism and a heating mechanism. The lamp body positioning mechanism comprises a push air cylinder, a lamp body positioning base and a floating positioning base. The push air cylinder installed on the workbench is connected with the lamp body positioning base. The floating positioning base is connected with the lamp body positioning base and arranged at the upper portion of the lamp body positioning base. A rivet head positioning plate on the floating positioning base is borne on a lower elastic body. The press riveting mechanism comprises a rivet pressing air cylinder, guide columns and a rivet pressing mechanism, wherein the rivet pressing air cylinder is connected with the rivet pressing mechanism. A pressing base of the rivet pressing mechanism is provided with pressing columns and air blowing pipes, and elastic push rods connected to the pressing base are opposite to the rivet head positioning plate. The rivet head grabbing mechanism comprises a support, a lifting rod and a movable rod which are connected. The heating mechanism comprises a heating furnace and a rotary disc, and the heating furnace and the rotary disc are fixed to the workbench. The plastic hot riveting device is reasonable in structure, rapid hot riveting and cooling can be achieved during multi-point riveting, the riveting quality can be ensured, and the riveting efficiency can be improved as well.

Description

technical field [0001] The invention relates to a plastic hot riveting device for a car lamp, which belongs to the technical field of car lamp processing. Background technique [0002] In the manufacture of automobile lamps, it is often encountered that the circuit board on the lamp body is riveted on the circuit board seat of the lamp body. See figure 1 As shown, the circuit board seat of the lamp body 1 is provided with a plurality of riveting columns 1-1 passing through the riveting holes on the circuit board 2, and the riveting columns 1-1 are deformed and wrapped on the circuit board 2 through the riveting pressure columns, and the The circuit board 2 is fixed by riveting. [0003] At present, cold riveting and hot riveting are mainly used for riveting of headlights, but cold riveting is mainly used in occasions where there are few riveting posts, simple circuit boards, and the requirements for riveting surface quality are not very high. There are relatively many riv...
