Vehicle body glue spraying shielding device and vehicle body glue sprayer

Abstract

The invention provides a vehicle body glue spraying shielding device, comprising a bearing rack, a hollow truncated conical shielding disc, a driving device, a driving gear, and a spray gun, an idler gear, a glue scraper and a glue collecting drum which are arranged on the bearing rack; the shielding disc is provided with outer teeth meshed with the idler gear; the driving gear is meshed with the outer teeth and is driven by the driving device; the large end of the shielding disc is closer to the spray gun than the small end of the shielding disc; the glue scraper clings to the internal surface of the shielding disc; the glue collecting drum is positioned below the glue scraper and is used for collecting the residual glue scraped by the glue scraper. The invention also provides a vehicle body glue sprayer with the shielding device. The vehicle body glue spraying shielding device and the vehicle body glue sprayer have the advantages of being high in production efficiency, good in consistency, more environment-friendly, more cost-saving and the like.

Description

technical field [0001] The invention relates to the field of automobile production lines, in particular to a shielding device used in the glue spraying process of a vehicle body and a glue spraying device equipped with the shielding device. Background technique [0002] When the car is driving on the road, the stones on the road will hit the skirt of the car body at high speed, which will have a major impact on the appearance and corrosion resistance of the car. Therefore, in the production of car body painting, spraying PVC glue on the skirt of the car body is an important means for car body to prevent stone impact. At present, this technology is widely used in car painting lines. In the prior art, the diffusion of the glue sprayed by the spray gun is irregular, so the unsprayed area of ​​the car body must be covered before spraying the glue. The masking method is to manually stick a masking paper on the unsprayed area of ​​the car body to prevent glue spraying. The edge s...

Problems solved by technology

[0003] The prior art has the following disadvantages: 1. The covering of the vehicle body is manual operation, which is random, easily asymmetrical from left to right, and the accuracy of the covering position is low, and the effect is poor; 2. The manual covering operation takes a relatively long time and the production efficiency is low; 3. The masking paper used for masking can only be used once and cannot be reused, resulting in a waste of resources. At the same time, the masking paper after use is solid waste and needs to be disposed of, resulting in an increase in the overall cost of production; 4. The manual operation of masking affects the occupation of employees. Hazardous to health, there is a risk of occupational disease
