Description

Technical Field

[0001] This application relates to the technical field of spraying devices, and particularly to a spraying device for automotive parts. Background Art

[0002] Currently, automotive parts refer to the various separate components that make up a complete vehicle. Generally, automotive parts need to be painted. Painting can effectively prevent parts from rusting and corroding, extend their service life, and create diverse visual appearances to meet the personalized needs of consumers. During the spraying process of automotive parts, an efficient spraying device for automotive parts is often used.

[0003] In the related art, when spraying automotive parts, most parts are transported by a conveyor chain at a high place and suspended parts are transferred. Then, a spraying gun is manually used to spray the suspended parts. When spraying different positions on the surface of the parts, the parts need to be rotated or the position needs to be changed manually, which brings problems of manual labor and low work efficiency, so it needs to be improved. Summary of the Invention

[0004] The purpose of this application is to provide a spraying device for automotive parts, which has the advantages of reducing manual labor, improving processing efficiency, being able to adapt to parts of different sizes, being convenient to move, convenient to change the spraying position, and being energy-saving and efficient.

[0005] The spraying device for automotive parts provided by this application adopts the following technical solutions:

[0006] A spraying device for automotive parts includes a base and moving wheels arranged at the bottom end of the base. A chassis is rotatably arranged on the base. A group of brackets are symmetrically arranged on the chassis. A spraying gun is arranged on one of the brackets, and a drying gun is arranged on the other bracket. A storage tank is arranged inside the base, and the storage tank is interconnected with the spraying gun through a pump body. A rotating assembly is arranged on the base, and the rotating assembly is used to drive the chassis to rotate. The bracket includes a fixed frame and a lifting frame. The fixed frame is connected to the chassis. The spraying gun and the drying gun are arranged on the lifting frame. A lifting groove is opened at the top end of the fixed frame, and the lifting frame is slidably arranged in the lifting groove. A lifting assembly is arranged between the fixed frame and the lifting frame, and the lifting assembly is used to drive the lifting frame to slide in the lifting groove.

[0007] By adopting the above technical solution, when spraying automotive parts, the conveying device transports the automotive parts, and the position of the device can be changed by moving the base, enabling the parts to pass between the two brackets. When the parts are located between the two brackets, the spray gun sprays the paint in the discharge chute, and at the same time, the drying gun sprays high-temperature gas to dry the surface of the parts. At this time, the rotating assembly is used to drive the chassis to rotate, and the chassis drives the brackets to rotate. When the brackets rotate, the spray gun and the drying gun can spray and dry different positions on the surface of the parts. Or the lifting assembly is used to drive the lifting frame to slide in the lifting chute to change the height of the lifting frame, and thus change the heights of the spray gun and the drying gun, facilitating the spray gun and the drying gun to spray parts at different heights. The entire process does not require manual operation, reducing manual labor. The rotating spray gun and drying gun can spray and dry different positions on the surface of the parts, improving the processing efficiency, being able to accommodate parts of different sizes, and being convenient to move and change the spraying position.

[0008] Optionally, the rotating assembly includes a first motor, a driving bevel gear, and a driven bevel gear. The driven bevel gear is integrally provided at the bottom end of the chassis. A rotating groove for inserting and rotating the driven bevel gear is formed in the base, and the rotating groove is adapted to the driven bevel gear. The first motor is arranged in the rotating groove, the driving bevel gear is connected to the driving shaft of the first motor, and the driving bevel gear meshes with the driven bevel gear.

[0009] By adopting the above technical solution, when it is necessary to control the rotation of the chassis to drive the brackets to rotate, the first motor drives the driving bevel gear to rotate. The driving bevel gear abuts against the driven bevel gear, thereby driving the driven bevel gear to slide in the rotating groove, and then driving the chassis to rotate. When the brackets rotate with the chassis, the spray gun and the drying gun can rotate around the parts to spray and process different positions on the surface of the parts.

[0010] Optionally, a sensor is provided on the side wall of the bracket. The sensor is connected to a controller, and the controller is used to control the first motor to stop working when the sensor senses the parts.

[0011] By adopting the above technical solution, when the brackets rotate with the chassis, the sensor uses ultrasonic induction. If the bracket is close to the sensor, the sensor can sense the automotive parts. At this time, the controller controls the first motor to stop working and stops the rotation of the brackets, thereby reducing the collision between the brackets and the parts.

[0012] Optionally, the lifting assembly includes a mounting frame, a rotating shaft, a rotating disk, a spiral blade, and a rack. The mounting frame is fixedly arranged on the side wall of the fixed frame. The rotating shaft is rotatably arranged on the mounting frame. The rotating disk is connected to one end of the rotating shaft facing the fixed frame. The spiral blade is arranged on the rotating disk. A connecting groove is penetrated through the inner wall of the lifting groove. The rack is integrally arranged on the side wall of the lifting frame. The spiral blade penetrates through the connecting groove and meshes with the rack.

[0013] Optionally, the lifting assembly further includes a handle, and the handle is arranged at one end of the rotating shaft away from the rotating disk.

[0014] By adopting the above technical solution, when it is necessary to change the height of the spray gun or the drying gun, by holding the handle, the handle drives the rotating shaft to rotate, the rotating shaft drives the rotating disk to rotate, and the rotating disk drives the spiral blade to rotate. When the spiral blade rotates, the rack abuts against the side wall of the spiral blade. Since the spiral blade is spiral, when the spiral blade rotates, it continuously drives the rack to lift, thereby driving the lifting frame to slide in the lifting groove. And the rack always abuts against the side wall of the spiral blade under the gravity of the lifting frame, so that the height of the lifting frame can be quickly fixed, the height of the spray gun or the drying gun can be quickly changed, and it is convenient to process parts of different specifications and models.

[0015] Optionally, a swinging hole is formed in the lifting frame. The spray gun is connected with a swinging rod. The swinging rod penetrates through the swinging hole and is rotatably connected with the inner wall of the swinging hole. A second motor is arranged on the lifting frame. The driving shaft of the second motor is connected with a cam. A torsion spring is arranged at the rotational connection between the swinging rod and the inner wall of the swinging hole. The torsion spring urges the swinging rod to abut against the end wall of the cam.

[0016] By adopting the above technical solution, when the spray gun is performing spraying operations, the second motor drives the cam to rotate, and the torsion spring always urges the swinging rod to abut against the end wall of the cam. The cam abuts against the swinging rod, thereby driving the swinging rod to swing back and forth in the swinging hole, which can effectively expand the spraying range of the spray gun and thus improve the processing efficiency.

[0017] Optionally, a recovery groove is penetrated through the surface of the chassis. The recovery groove is located directly above the storage groove. A filtering member is arranged in the recovery groove.

[0018] Optionally, the filtering member includes a filtering frame and a filtering net. The filtering net is arranged in the filtering frame. Filtering grooves for inserting and abutting the filtering frame are formed on the inner wall of the recovery groove.

[0019] By adopting the above technical solution, when spraying, the excess paint will drip from the surface of the part. At this time, the paint can flow back into the storage tank through the recovery tank after being filtered by the filter element, realizing the recovery of the excess paint, thus reducing waste and achieving the purpose of energy conservation and environmental protection. At the same time, through the cooperation between the filter tank and the filter frame, the filter element can be quickly disassembled, facilitating the cleaning of the filter net.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. By setting the base, moving wheels, chassis, bracket, spray gun, drying gun, storage tank, rotating assembly, fixing frame, lifting frame, lifting groove and lifting assembly, when spraying automotive parts, the rotating assembly is used to drive the chassis to rotate, the chassis drives the bracket to rotate, and when the bracket rotates, the spray gun and the drying gun can spray and dry different positions on the surface of the part. Or the lifting assembly is used to drive the lifting frame to slide in the lifting groove, changing the height of the lifting frame, and then changing the height of the spray gun and the drying gun. The whole process does not require manual operation, reducing the manual labor.

Detailed implementation mode

[0029] The following is combined with the attached Figure 1 - attached Figure 4 , and a further detailed description of this application will be given.

[0030] The embodiment of this application provides a spraying device for automobile parts. Referring to Figure 1 and Figure 2 , it includes a base 1 and moving wheels 11 arranged at the bottom end of the base 1. The base 1 can be moved through the moving wheels 11. A chassis 12 is rotatably arranged on the base 1, and a rotating assembly 4 is arranged between the base 1 and the chassis 12. A group of supports 2 are symmetrically arranged on the chassis 12. The supports 2 are arranged in the vertical direction. A spray gun 31 is arranged on one of the supports 2, and a drying gun 32 is arranged on the other support 2. A material storage tank 13 for storing paint is opened on the surface of the base 1, and the spray gun 31 and the material storage tank 13 are interconnected through a pump body. When spraying automobile parts, the conveying equipment transports the automobile parts. The position of this device can be changed by moving the base 1, so that the parts pass between the two supports 2. When the parts are between the two supports 2, the spray gun 31 sprays the paint in the material outlet tank, and at the same time the drying gun 32 sprays high-temperature gas to dry the surface of the parts. The rotating assembly 4 is used to drive the chassis 12 to rotate, the chassis 12 drives the supports 2 to rotate, and when the supports 2 rotate, the spray gun 31 and the drying gun 32 can spray and dry different positions on the surface of the parts.

[0031] Referring to Figure 1 and Figure 2, the rotating assembly 4 includes a first motor 41, a driving bevel gear 42 and a driven bevel gear 43. The driven bevel gear 43 is integrally provided at the bottom end of the chassis 12. The driven bevel gear 43 and the chassis 12 are coaxially arranged. A rotating groove 14 for the driven bevel gear 43 to be inserted and rotated is formed in the base 1. The rotating groove 14 is adapted to the driven bevel gear 43. The first motor 41 is fixedly arranged in the rotating groove 14. The driving bevel gear 42 is connected to the driving shaft of the first motor 41. The driving bevel gear 42 meshes with the driven bevel gear 43. When it is necessary to control the rotation of the chassis 12 to drive the bracket 2 to rotate, the first motor 41 drives the driving bevel gear 42 to rotate. The driving bevel gear 42 abuts against the driven bevel gear 43, thereby driving the driven bevel gear 43 to slide in the rotating groove 14, and then driving the chassis 12 to rotate. When the bracket 2 rotates with the chassis 12, the spray gun 31 and the drying gun 32 can rotate around the part to spray different positions on the surface of the part.

[0032] Referring to Figure 1 , a sensor 10 is arranged on the side wall of the bracket 2. The sensor 10 is an ultrasonic sensor. The sensor 10 is connected to a controller. When the bracket 2 rotates with the chassis 12, the sensor 10 emits ultrasonic waves for induction. If the bracket 2 is close to the sensor 10, the sensor 10 can sense the automotive part. At this time, the controller controls the first motor 41 to stop working and stops the rotation of the bracket 2, so as to reduce the collision between the bracket 2 and the part.

The rotating disk 53 is connected to one end of the rotating shaft 52 facing the fixed frame 21. The handle 56 is arranged at one end of the rotating shaft 52 away from the rotating disk 53. The spiral blade 54 is integrally arranged on the rotating disk 53. The spiral blade 54 is arranged in a spiral shape. A connecting groove 212 is penetrated through the inner wall of the lifting groove 211. The rack 55 is integrally arranged on the side wall of the lifting frame 22. The length direction of the rack 55 is arranged along the length direction of the lifting frame 22. The spiral blade 54 penetrates through the connecting groove 212 and meshes with the rack 55. By holding the handle 56, the handle 56 drives the rotating shaft 52 to rotate. The rotating shaft 52 drives the rotating disk 53 to rotate. The rotating disk 53 then drives the spiral blade 54 to rotate. When the spiral blade 54 rotates, the rack 55 abuts against the side wall of the spiral blade 54. Since the spiral blade 54 is spiral, when the spiral blade 54 rotates, it continuously abuts against the rack 55 to drive the rack 55 to lift, thereby driving the lifting frame 22 to slide in the lifting groove 211. And the rack 55 always abuts against the side wall of the spiral blade 54 under the gravity of the lifting frame 22, so that the height of the lifting frame 22 can be quickly fixed, the height of the spray gun 31 or the drying gun 32 can be quickly changed, which is convenient for processing parts of different specifications and models, and improves the applicability of the device.

[0034] Referring to Figure 1 and Figure 3 , a swing hole 6 is penetrated through the side wall of the lifting frame 22. The spray gun 31 is connected with a swing rod 61. The swing rod 61 penetrates through the swing hole 6 and is rotatably connected to the inner wall of the swing hole 6. A second motor 7 is fixedly arranged on the lifting frame 22. The driving shaft of the second motor 7 is connected with a cam 71. A torsion spring is arranged at the rotational connection between the swing rod 61 and the inner wall of the swing hole 6. The torsion spring urges the swing rod 61 to abut against the end wall of the cam 71. When the gun is performing spraying operation, the second motor 7 drives the cam 71 to rotate. And the torsion spring always urges the swing rod 61 to abut against the end wall of the cam 71. The cam 71 abuts against the swing rod 61, thereby driving the swing rod 61 to swing back and forth in the swing hole 6, which can effectively expand the spraying range of the spray gun 31, and thus improve the processing efficiency.

[0035] Referring to Figure 2, a recovery groove 8 is provided through the surface of the chassis 12. The recovery groove 8 is located directly above the material storage groove 13, and a filter member 9 is provided in the recovery groove 8. The filter member 9 includes a filter frame 91 and a filter net 92. The filter net 92 is arranged in the filter frame 91, and a filter groove 81 for inserting and abutting the filter frame 91 is formed on the inner wall of the recovery groove 8. When spraying, the excess paint will drip from the surface of the part. At this time, the paint can flow back to the material storage groove 13 through the recovery groove 8 after being filtered by the filter member 9, realizing the recovery of the excess paint, thereby reducing waste and achieving the purpose of energy conservation and environmental protection; and by using the cooperation between the filter groove 81 and the filter frame 91, the filter member 9 can be quickly disassembled, facilitating the cleaning of the filter net 92.
