Description

Technical Field

[0001] The utility model relates to the field of spray gun cleaning, in particular to an external cleaning device for a robot spray gun. Background Technique

[0002] During the spraying operation, improper operation of the spray gun will affect the spraying effect of the product. Several issues to note for a good spraying effect are as follows:

[0003] First: The appropriate spraying distance. The distance between the nozzle outlet and the object to be coated is called the spraying distance. The smaller the distance, the greater the spraying pressure, and the greater the impact of the air pressure on the product, resulting in an uneven coating.

[0004] Second: The cleaning of the outside of the nozzle. If not cleaned, powder and ash will be mixed in the coating during the spraying process, thus affecting the spraying quality. Generally, after construction, routine maintenance and cleaning of the spray gun equipment are carried out. The traditional steps are for workers to enter the powder room with a blowing gun and then clean the equipment. However, this operation requires manual labor and the cleaning is not thorough. Secondly, during the manual cleaning process, powder and ash will still fall into the powder room, with low powder and ash recovery efficiency and still having an impact on subsequent spraying operations. Content of the Utility Model

A first track groove is opened at the bottom edge of the cleaning cover. The rotating disk is sleeved outside the cleaning cover, and the inner ring of the rotating disk is located in the first track groove at the bottom of the cleaning cover. A second track groove is also opened on the rotating disk, and the second track groove is movably connected to the bottom of the housing. A robot spray gun inlet is opened in the middle of the tops of the cleaning cover and the housing.

[0008] Preferably, the bottom of the air gun seat is fixed inside the cleaning cover and is connected to an external air pump through an air duct. High-pressure gas is introduced into the air gun seat through the air duct, and the spray gun inside the cleaning cover is cleaned through the nozzle.

[0009] Preferably, the cleaning cover and the housing are fixedly connected by connecting screws at the top, so that the housing will not rotate along with the rotating disk during the rotation process.

[0010] Preferably, a gear ring is further arranged at the bottom of the rotary disk, and the gear ring meshes with an external gear. The utility model is arranged on the inner wall of the powder room. After the spraying gun finishes the operation, the spraying gun only needs to be inserted into the utility model to complete the cleaning of the external powder ash.

[0011] Preferably, a plurality of brushes are further arranged on the rotary disk, the brushes are located between the outer wall of the cleaning cover and the inner wall of the housing, and the number of the brushes is not less than nine.

[0012] Preferably, a dust outlet pipe is further arranged on the housing, and the dust outlet pipe is connected with an external fan to collect the cleaned powder ash through negative pressure.

[0013] The beneficial effects of the utility model are as follows:

[0014] The utility model is arranged on the inner wall of the powder room. After each spraying is finished, only the robot spraying gun needs to be controlled to be inserted into the interior for cleaning. The nozzles are circumferentially and arrayedly distributed to clean the powder ash outside the spraying gun in all directions. Then, the powder ash inside is sucked out from the dust outlet pipe through negative pressure. At the same time, the arranged brushes can clean the outer wall of the cleaning cover and the inner wall of the housing during the rotation process, avoiding the accumulation of powder ash inside. The cleaning process replaces the traditional manual cleaning, and no powder ash will fall into the powder room during the cleaning process. The powder ash recovery efficiency is high, and the influence of the powder ash on the spraying operation is reduced. Description of the Drawings

[0023] Example 1: Refer to Figures 1-6 , an external cleaning device for a robot spray gun, including a cleaning cover 1, a gas gun seat 2, a nozzle 3, a straight groove 4, a rotating disk 5 and a housing 6. A plurality of positioning screws 7 are provided at the bottom of the cleaning cover 1, and the cleaning cover 1 is directly fixed on the inner wall of the powder room through the positioning screws 7. A plurality of gas gun seats 2 are arranged in a circumferential array inside the cleaning cover 1. A plurality of nozzles 3 are provided on the upper part of each gas gun seat 2. A plurality of straight grooves 4 are opened on the cleaning cover 1. A first track groove 8 is opened at the bottom edge of the cleaning cover 1. The rotating disk 5 is sleeved outside the cleaning cover 1, and the inner ring of the rotating disk 5 is located in the first track groove 8 at the bottom of the cleaning cover 1. A second track groove 9 is also opened on the rotating disk 5, and the second track groove 9 is movably connected to the bottom of the housing 6. A robot spray gun inlet 10 is opened in the middle of the tops of the cleaning cover 1 and the housing 6.

[0024] The rotation of the rotating disk 5 is driven by an external motor. The external motor meshes with a gear ring 13, thereby causing the rotating disk 5 to rotate.

[0025] The bottom of the gas gun seat 2 is fixed inside the cleaning cover 1 and is connected to an external air pump through an air duct 11.

[0026] The tops of the cleaning cover 1 and the housing 6 are fixedly connected through connecting screws 12. The connecting screws 12 fix the cleaning cover 1 and the housing 6 to prevent the housing 6 from rotating during the rotation of the rotating disk 5.

[0028] Working principle:

[0029] First, install the present utility model on the inner wall of the powder room. Then, connect the air passage 11 and an external air pump through an air pipe. After each operation of the spray gun, control the robot to align the outside of the spray gun with the spray gun inlet 10. Then, start the external air pump. The external air pump transmits high-pressure gas to each nozzle 3 through the air gun seat 2 to clean the outside of the spray gun without dead angles. At the same time, start the external motor and external fan. The powder ash inside first enters the space between the cleaning cover 1 and the housing 6 through the straight slot 4, and then is sucked out from the inside through the dust outlet pipe 15. Meanwhile, to prevent powder ash from accumulating in the cleaning cover 1 and the housing 6, start the motor through an external power supply. The motor drives the gear ring 13 to rotate. During the rotation of the gear ring 13, the rotating disk 5 is driven to rotate around the outside of the cleaning cover 1. During this process, the housing 6 remains stationary, and the brush 14 installed on the rotating disk 5 will clean the inner wall. The cleaned powder ash and the powder ash inside the cleaning cover 1 are sucked out together through the dust outlet pipe 15.

[0030] A number of brushes 14 are also arranged on the rotating disk 5. The brushes 14 are located between the outer wall of the cleaning cover 1 and the inner wall of the housing 6, and the number of the brushes 14 is not less than nine.

[0031] A dust outlet pipe 15 is also arranged on the housing 6. The dust outlet pipe 15 is connected to an external fan. During the internal cleaning process, the space between the spray gun and the spray gun inlet 10 is in a sealed state, so a vacuum will be formed inside, which is convenient for sucking powder ash and the powder ash will not fall into the powder room.

[0032] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
