[0002] Electric vehicles, that is, electric-driven vehicles, also known as electric-drive vehicles, are divided into AC electric vehicles and DC electric vehicles. Electric vehicles usually refer to vehicles that use batteries as energy sources, convert electrical energy into mechanical energy movement through controllers, motors and other components, and control the current size to change the speed of the vehicle. It conforms to the trend of energy conservation and environmental protection, greatly facilitates short-distance transportation, and most importantly, plays an important role in the national economy by saving and protecting energy and the environment.

[0003] A large number of plastic parts are used in the internal and external coverings of electric vehicles. Some plastic connection positions need to be sealed and fixed with sealant. Due to the irregular edges of electric vehicle plastic parts, workers need to apply the glue manually. However, manual gluing makes it difficult to control the glue output speed and amount, which can easily lead to uneven glue application. Therefore, gluing equipment is needed to control the distance between the glue output hose and the edge of the plastic part and effectively control the glue output speed. Utility Model Content
