Problems solved by technology

Because the car is affected by the external environment throughout the year, the car sealing strip is often prone to deformation and aging due to high temperature, low temperature, strong light irradiation and harsh environment corrosion, which seriously affects the sealing performance of the sealing strip. The shock performance and service life will affect the safety of the car. It is not only a consumable item in the auto parts, but also an unstable factor affecting the safety of the car.
[0003] In the prior art, the sealing strip of the automobile is affected by the spraying process, the combination degree of the coating and the sealing strip is not high, the service life is not long, and sealing problems are prone to occur

Embodiment Construction

[0030] The invention provides an automobile frameless sealing strip spraying system, which includes a conveyor line connected end to end, and hangers are arranged at equal distances on the conveyor line, and the hanger is used for placing the automobile seal strip. It is a card slot with the same shape as the car sealant strip. The car sealant strip is clamped in the card slot to achieve fixation, which can avoid the deformation of the car sealant, improve the spraying quality, and the hanger can move on the conveyor line. Specifically, It moves along the direction of the conveying line, and the moving path of the hanger is sequentially provided with a feeding area, a first preheating area, a first spraying area, a second preheating area, a second spraying area, a first drying area, The third spraying zone, the second drying zone, the cooling zone and the blanking zone.

[0031] The feeding area is used for manual feeding, the first preheating area is used for primer preheatin...

Abstract

The invention provides an automobile frameless sealing strip spraying method. The automobile frameless sealing strip spraying method comprises the following steps of S1, surface cleaning; s2, loading the workpiece; s3, prime coat preheating; s4, spraying a base coat; s5, prime coat curing; s6, primer spraying; s7, primer drying; s8, spraying finish paint; s9, drying the finish paint; s10, cooling is conducted; and S11, discharging the workpiece. According to the automobile frameless sealing strip spraying method, the spraying process is optimized and improved, the spraying quality and the product quality are improved, the service life of the sealing strip is prolonged, and the sealing performance of the sealing strip is improved.

Description

technical field [0001] The invention relates to a spraying method, in particular to a spraying method for a frameless sealing strip of an automobile. Background technique [0002] Automotive frameless sealing strips are widely used in car body parts such as front and rear windshields, doors, windows, seats, sunroofs, engine compartments, trunks, etc., in addition to sealing, shock absorption, waterproof, dustproof, sound insulation, decoration and other functions It also plays a role in filling the gap between the body parts, making up for assembly errors, etc., and protecting and maintaining the driver and the vehicle. Due to the influence of the external environment throughout the year during the use of the car, the automobile sealing strip is often prone to deformation and aging due to high temperature, low temperature, strong light irradiation and corrosion in harsh environments, which seriously affects the sealing performance of the sealing strip. It is not only a cons...
