Description

Technical Field

[0001] The invention relates to the technical field of spray painting, and in particular to a spray painting device for cabinet production. Background Art

[0002] The power distribution cabinet, also known as the distribution box, is the final equipment of the power distribution system, which is used to distribute electrical energy to various electrical equipment to meet various power needs. It usually assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet according to the electrical wiring requirements. The power distribution cabinet is divided into fixed panel type power distribution cabinet, protective type power distribution cabinet and drawer type power distribution cabinet. Among them, the fixed panel type power distribution cabinet has a panel on the front, and the back and sides are open.

[0003] In order to improve the protection performance and aesthetics of the distribution cabinet, it is usually necessary to paint the distribution cabinet to form a protective layer on the surface of the distribution cabinet to improve its anti-corrosion, fireproof, insulation, dustproof and waterproof performance, and prevent electrical equipment from being affected by the external environment such as wind, rain, corrosion and other harsh climates, thereby extending the service life of the equipment.

[0004] A Chinese patent with authorization announcement number CN116586220B discloses a spraying device for processing electric control cabinets, which includes a support table, a metal plate body and a connecting column. The front and rear ends of the top of the support table are movably connected with a pulley roller, the bottom of the outer surface of the pulley roller is movably connected with a limiting block, and the inner cavity on one side of the limiting block is fixedly connected with a tension spring.

[0005] The above patent achieves the function of spraying paint evenly on the metal plate of the electric control cabinet through the coordination between the airbag, eccentric cam, pulley roller and U-shaped piston. When the metal plate body contacts and moves with the pulley roller, the pulley roller drives the eccentric cam to rotate, and the end of the U-shaped piston located inside the connecting column moves toward the outside, thereby changing the width of the paint sprayed by the atomizing nozzle. Since the device sprays the surface of the metal plate body at one time, it solves the problem of unevenness caused by multiple spraying by the operator.

[0006] However, when spraying paint on the inside of the cabinet, it is not possible to spray paint evenly inside the cabinet by rotating the cabinet horizontally, so that there are dead spots for spraying. Summary of the invention

The nozzle 201 is an electric telescopic tube that can be extended or shortened. One end of the nozzle 201 is fixedly connected to the connecting pipe 16, and the other end is fixedly connected to the nozzle 202. The nozzle 201 can connect the nozzle 202 and the connecting pipe 16. A receiving chamber is provided in the lifting seat 14, and the receiving chamber is used to hold the spray paint. The spray paint can flow into the connecting pipe 16 and enter the nozzle 202 through the nozzle 201, and finally be sprayed in the spray booth 1 through the nozzle 202. A contact switch 21 is also provided on the top of the spray booth 1. The contact switch 21 is located between the two sections of the first tooth groove 101, and can stop with the rotating seat 3. A control panel is provided in the spray booth 1. The contact switch 21 is electrically connected to the control panel through wires, and the control panel is electrically connected to each nozzle 201 through wires.

[0042] According to the cabinet production paint spraying device of the embodiment of the present invention, the cabinet is lifted by the first pull rope 8 and the second pull rope 9, and the conveying mechanism 2 drives the rotating seat 3 to move slowly from the back to the front, so that the cabinet slowly enters the spray room 1 from the back to the front. At this time, the front and back of the cabinet are facing the spray guns 20 on the left and right sides of the spray room 1. The lifting seat 14 moves from top to bottom, and the spray gun 20 sprays paint on the front and back of the cabinet at the same time. Since the back of the cabinet is an open structure, the spray gun 20 on the right side can also spray paint on the inner wall of the front of the cabinet during the painting process. When the lifting seat 14 moves to the lowermost end, the painting operation on the front and back of the cabinet and the inner side of the front is completed. At this time, the spraying is stopped, and the rotating seat 3 is about to contact the first tooth groove 101 on the back side. When the rotating seat 3 passes the first tooth groove 101 on the rear side, the rotating seat 3 meshes with the first tooth groove 101 on the rear side, thereby rotating 90 degrees. The rotating seat 3 drives the cabinet to rotate horizontally 90 degrees through the pull rope, so that the two sides of the cabinet face the spray guns 20 on both sides of the spray booth 1. When the rotating seat 3 leaves the first tooth groove 101 on the rear side, the rotating seat 3 stops at the contact switch 21, and the contact switch 21 transmits an electrical signal to the control board. The control board controls the corresponding spray gun 20 to retract, thereby ensuring that the distance between the cabinet and the nozzle 202 remains unchanged.

[0043] After the rotating seat 3 leaves the first tooth groove 101, the first gear 6 moves forward along the second tooth groove 102, the second gear 7 moves forward along the third tooth groove 103, the first gear 6 rotates and slides in the first thread groove 41, thereby pushing the first rod 4 to move upward, the first rod 4 pulls the left side of the cabinet upward through the first pull rope 8, the second gear 7 rotates and slides in the second thread groove, thereby pushing the second rod 5 to move downward, the second rod 5 releases the second pull rope 9, so that the right side of the cabinet rotates downward, when the first rod 4 moves upward to the highest point and the second rod 5 moves to the lowest point, the cabinet rotates 45 degrees to the right as a whole, and at this time the first gear 6 continues to rotate and drives the first rod 4 to move downward, the first rod 4 releases the first pull rope 8, so that the left side of the cabinet rotates downward, the second gear 7 continues to rotate and drives the second rod 5 to move upward, the second rod 5 retracts the second pull rope 9, so that the right side of the cabinet is lifted upward, until the cabinet rotates 90 degrees to the left, at this time the first rod 4 moves to the lowest point, the second rod 5 moves to the highest point, the first gear 6 continues to rotate and drives the first rod 4 to move upward, the second gear 7 drives the second rod 5 to move downward, until the first gear 6 disengages from the second tooth groove 102, the second gear 7 disengages from the third tooth groove 103, at this time the cabinet rotates 45 degrees to the right and returns to a horizontal state. At the same time, the lifting seat 14 drives the spray gun 20 to move upward and sprays the two sides of the cabinet and the top and bottom surfaces of the cabinet. During the spraying process, the second driving member 18 drives the driving rod 19 to move left and right, and the driving rod 19 drives the fourth gear to rotate. The connecting pipe 16 rotates synchronously with the fourth gear, thereby driving the spray gun 20 to swing and making the nozzle 202 always facing the cabinet. Since the two sides of the cabinet are open structures, the spray gun 20 can spray the lower bottom surface and the upper top surface inside the cabinet. During the left and right rotation of the cabinet, the dead corners of the lower bottom surface and the upper top surface inside the cabinet can be exposed, and the spray gun 20 can spray the dead corners of the lower bottom surface and the upper top surface of the cabinet, thereby achieving comprehensive spraying of the cabinet.

[0044] After spraying is completed, the rotating seat 3 contacts the first tooth groove 101 on the front side, moves along the first tooth groove 101 and rotates 90 degrees, drives the cabinet to rotate horizontally 90 degrees through the pull rope, and leaves the spray room 1 from the front end of the spray room 1.
