Problems solved by technology

[0005] However, the existing dispensing process requires the adhesive to be preheated in advance, and then bonded after reaching a suitable bonding temperature. For the automotive instrument panel, the adhesive with a higher temperature is coated on the surface of the instrument, which is easy to cause Deformation of the instrument, and prolong the dispensing time and reduce the dispensing efficiency

Abstract

The invention discloses a waterproof dispensing process applicable to electric vehicle meters, and belongs to the field of automobile meter processing. The technical problems that in an existing dispensing process, adhesives need to be preheated and the dispensing efficiency is low are solved. According to the technical scheme, the waterproof dispensing process comprises the following steps that (1) a meter is clamped in a positioning jig; (2) an anti-electrostatic film and an active film are coated; (3) the adhesives are loaded in a heating bar of a dispenser, and a corresponding dispensing needle is installed in the dispenser; (4) dispensing parameters are set; and (5) the dispenser is started. The anti-electrostatic film can achieve an effective isolation effect, the active film has anactivating effect and can activate glue of the dispensing process so that the glue can have good viscidity, glue settlement can be reduced, the step of preheating the adhesives is replaced, and the dispensing efficiency is greatly improved.

Description

technical field [0001] The invention relates to the processing of auto parts, in particular to a waterproof dispensing process suitable for electric vehicle meters. Background technique [0002] From the assembly of a car to the landing of the whole car, a lot of complicated processes and links are required, including dispensing and soldering. As the name suggests, soldering is to assemble many spare parts together by welding, and dispensing process is also required in many places. Such as wire, power supply, glass, lamps and so on. Traditional dispensing is mostly done manually by workers. With the rapid development of automation technology, manual dispensing is far from meeting the needs of the industry and is gradually being replaced by automatic dispensing technology. [0003] The dispensing of automotive lamps is generally done by a silicone automatic dispensing machine. The main reason is that the silicone glue is elastic after curing and has moderate hardness. It can...
