Description

Technical Field

[0001] The invention relates to the technical field of sightseeing vehicle production spraying, in particular to an automatic spraying equipment for sightseeing vehicle covering parts. Background Art

[0002] Sightseeing buses are designed to have a low speed and are usually used in closed scenic areas. In order to save costs, reduce the overall weight of the sightseeing bus, and improve the vehicle's fuel economy and endurance, the covering parts of the sightseeing bus are usually made of materials with low structural strength and light weight, such as injection molding, fiberglass, and metal. In order to spread the paint evenly during painting, traditional painting equipment needs to stably clamp the covering parts when working. However, due to the low structural strength and light weight of the covering parts of the sightseeing bus, excessive clamping force can easily cause the covering parts to deform. In order to maximize the painting efficiency, existing painting equipment usually adopts two-point clamping when clamping the covering parts. When painting larger covering parts such as bumpers, front and rear surrounds, the two-point clamping method can easily cause the unclamped part to sink, which not only makes it more likely to cause deformation of the covering parts, but also causes uneven painting.

[0003] Based on this, the present invention designs an automatic painting device for sightseeing car covering parts to solve the above problems. Summary of the invention
