Description

Technical Field

[0001] The present invention relates to the technical field of spraying equipment, in particular to a spraying equipment for surface treatment of automobile hinges. Background Art

[0002] As crucial connectors for doors, hoods, trunks, and other areas, automotive hinges must possess not only excellent mechanical properties but also superior corrosion resistance and an aesthetically pleasing appearance. To reduce wear and corrosion, hinges are spray-coated. A powdered coating is electrostatically adsorbed onto the hinge surface and then cured at high temperatures to form a coating with excellent wear and corrosion resistance.

[0003] Existing surface spraying equipment typically uses a reversible fixture to clamp the workpiece. Through automated control, the fixture can be flipped during the spraying process, allowing the spray head to evenly cover all surfaces of the workpiece. This type of equipment is suitable for large or complex-shaped workpieces.

[0004] Another example is the Chinese patent with publication number CN113663853A. An anti-static powder spraying device for metal part production and processing discloses in its specification that "a metal part is placed between a first movable block and a second movable block, the metal part contacts a first pressure sensor, the first pressure sensor sends a signal when detecting that the pressure of the metal part reaches a preset value, the control module receives the signal and controls the first reduction motor and the heating module to start, the first reduction motor output shaft drives the first screw to rotate, the first screw drives the movable frame and its upper components to move rightward, and anti-static powder is sprayed onto the metal part through the nozzle", "the fourth movable plate rotates, the third torsion spring deforms, and when the cam separates from the fourth movable plate, the fourth movable plate is reset under the action of the third torsion spring, and the metal part is repeatedly shaken, thereby evenly shaking the anti-static powder on the metal part. After the third reduction motor is turned off, the metal part can be removed". During the spraying process, the workpiece needs to be clamped first, and then the powder on the workpiece is shaken evenly on the shaking mechanism after spraying. The above technical solution also requires clamping a single workpiece and shaking the powder evenly after spraying. The steps are cumbersome and cannot be used for spraying batches of parts.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0048] The feed port 105 provided at the top of the connecting frame 101 corresponds to one of the connecting openings 103 , and the discharge port 106 provided at the bottom of the connecting frame 101 corresponds to one of the connecting openings 103 ;

[0049] A spray box 107 is provided on the top of the spray rack 100. A spray head 108 is provided at the bottom of the spray box 107. The spray head 108 extends through the feed port 105 and the connecting opening 103 into the rotating frame 102.

[0050] The driving component provided on the spraying frame 100 is used to rotate the rotating frame 102, and the rotating frame 102 can rotate intermittently;

[0051] The driving component can lift the connecting frame 101 upward after rotating the rotating frame 102 by a preset angle, and the connecting frame 101 can fall quickly after moving upward to a preset height;

[0052] The driving component can move the position of the nozzle 108 before rotating the rotating frame 102 so that the nozzle 108 leaves the rotating frame 102, and the nozzle 108 can stop spraying powder when it moves to a preset position;

[0053] By setting up the connecting frame 101, the operator can put the hinge workpiece that needs to be sprayed into the connecting frame 101 and the rotating frame 102 from the feed port 105 and the connecting opening 103, and can open the nozzle 108 arranged at the bottom of the spray box 107, and the spray powder in the spray box 107 can enter the nozzle 108. After the nozzle 108 is turned on, the powder can be sprayed on the hinge workpiece, and the powder can be attached to the metal hinge due to static electricity. At the same time, the driving component can be turned on, and the driving component can rotate the rotating frame 102. The position of the nozzle 108 can be moved while the driving component rotates the rotating box frame, so that the nozzle 108 leaves the rotating frame 102 and leaves the connecting opening 103 from the connecting opening 103, so as to avoid subsequent When the rotating frame 102 is rotated, the position relationship of the nozzle 108 affects the rotation of the rotating frame 102. The nozzle 108 is extended into the rotating frame 102. When the nozzle 108 sprays powder, the powder will not be sprayed to the outside of the rotating frame 102 due to the height relationship of the nozzle 108, causing the problem of invalid spraying. Further, when the nozzle 108 moves upward to a preset position, it can stop spraying powder, avoiding the problem of invalid spraying caused by the powder being sprayed on the outside of the rotating frame 102 after the nozzle 108 leaves the rotating frame 102. When the rotating frame 102 rotates, the multiple ridges 104 provided therein can move the hinge to disturb the hinge. When spraying, the powder adheres to the hinge at the upper part of the hinge in the pile. 2 During rotation, the convex strips 104 disturb the multiple hinges, and a cavity of a certain height is formed between the convex strips 104 and the inner wall of the rotating frame 102. The hinge at the bottom can be in the cavity. As the rotating frame 102 rotates, the hinge in the cavity can be brought out. After the driving component rotates the rotating frame 102 by a preset angle, one of the multiple connection openings 103 thereon corresponds to the position of the nozzle 108 again. After the driving component rotates the rotating frame 102 by a preset angle, the position of the connecting frame 101 can be lifted upward. The movement of the connecting frame 101 can drive the movement of the rotating frame 102. The provided connection openings 103 can prevent the rotating frame 102 from interfering with the nozzle 108, and can fall quickly when the connecting frame 101 moves upward to the preset position. , so as to shake the hinge attached to the cavity after the rotation of the rotating frame 102, and shake the hinge above the hinge pile to receive the next spraying. At the same time, the excess powder attached to the hinge can be shaken off during the shaking, so that the powder can be more evenly attached to the hinge workpiece. After multiple rotations of the rotating frame 102, the stacked hinge workpieces can be sprayed, achieving the purpose of spraying multiple hinges, solving the spraying equipment in the prior art. The present application solves the problem that the workpiece needs to be clamped first during the spraying process, and the powder on the workpiece is evenly shaken on the shaking mechanism after spraying. The above technical solution also requires clamping a single workpiece and shaking the powder evenly after spraying, and the steps are cumbersome.The problem of not being able to spray parts in batches.

[0054] As a further solution of the present invention, the driving component includes a bracket 200 connected to the spray frame 100, a support rod 201 is slidably connected to the bracket 200, a first shaft 202 is rotatably connected to the bracket 200, a first gear 203 is connected to the first shaft 202, a second shaft 204 is rotatably connected to the support rod 201, a second shaft 204 is provided with a second gear 205 adapted to the first gear 203, a sleeve 206 is connected to the connecting frame 101, the second shaft 204 passes through the sleeve 206 and is connected to the rotating frame 102, and the first gear 203 is an incomplete gear;

[0055] By setting the first shaft 202, during application, the operator can rotate the first shaft 202. The rotation of the first shaft 202 can drive the first gear 203 thereon to rotate. When the first gear 203 rotates to a preset angle, it can engage with the second gear 205 and drive the second gear 205 to rotate, thereby allowing the second shaft 204 to rotate, so as to drive the rotating frame 102 to rotate a preset angle.

[0056] As a further embodiment of the present invention, the driving component further includes a third shaft 300 connected to the bracket 200, a third gear 301 adapted to the first gear 203 is connected to the third shaft 300, a connecting frame 302 is slidably connected to the spray frame 100, a first spring 303 is connected between the connecting frame 302 and the spray frame 100, a sleeve 206 is fixed to the connecting frame 302, a second spring 304 is connected between the support rod 201 and the bracket 200, and a fourth shaft 305 is further rotatably connected to the bracket 200, a cam 306 is connected to the fourth shaft 305, and a first chain 307 is connected between the third shaft 300 and the fourth shaft 305;

[0057] By setting the third shaft 300, after the first shaft 202 rotates through the first gear 203 and the second gear 205 to rotate the second shaft 204 and the rotating frame 102, the first gear 203 is disengaged from the second gear 205 and the first gear 203 is engaged with the third gear 301, so that the third shaft 300 can rotate. The rotation of the third shaft 300 can rotate the fourth shaft 305 through the first chain 307. The rotation of the fourth shaft 305 can make the protrusion of the cam 306 touch the connecting frame 302 to move the connecting frame 302. The movement of the connecting frame 302 can allow the connecting frame 101 to move upward through the sleeve 206, so as to achieve the purpose of allowing the connecting frame 101 to move upward after the rotating frame 102 rotates.

[0058] As a further solution of the present invention, a motor 308 is connected to the spraying frame 100, and a second chain 309 is connected between the motor 308 and the first shaft 202;

[0059] By providing the motor 308 , the motor 308 and the second chain 309 can provide driving force for the rotation of the first shaft 202 .

[0060] As a further embodiment of the present invention, a first tube 400 is connected to the spray box 107, a second tube 401 is slidably connected to the bottom of the first tube 400, a third spring 402 is connected between the first tube 400 and the second tube 401, and the spray head 108 is connected to the bottom of the second tube 401 and communicates with the second tube 401, the first tube 400 and the spray box 107;

[0061] By setting the first tube 400, the powder in the spray box 107 can enter the first tube 400 and the second tube 401, and the nozzle 108 can receive the powder in the second tube 401. When used, the position of the second tube 401 can be moved upward to allow the second tube 401 to drive the nozzle 108 to move, so as to achieve the purpose of allowing the nozzle 108 to leave the rotating frame 102.

[0062] As a further solution of the present invention, a reel 500 is provided on the second shaft 204, a connecting rod 501 slidably connected to the spraying frame 100 is connected to the second tube 401, a guide shaft 502 is rotatably connected to the spraying frame 100, and a traction rope 503 is connected to the reel 500, which passes around the guide shaft 502 and is connected to the connecting rod 501;

[0063] By setting up the reel 500, the reel 500 can be rotated during use. The rotation of the reel 500 can reel in the traction rope 503. The traction rope 503 is pulled to move the position of the connecting rod 501. The upward movement of the connecting rod 501 can move the second tube 401 upward, so as to achieve the purpose of allowing the nozzle 108 to leave the connecting opening 103.

[0064] As a further embodiment of the present invention, a first ring 504 is connected to the second shaft 204, and the second gear 205 is rotatably connected to the first ring 504. A plurality of first limiting bars 505 are connected to the outer wall of the first ring 504, and a plurality of second limiting bars 506 are connected to the inner wall of the second gear 205. A fourth spring 507 is connected between the first limiting bars 505 and the second limiting bars 506. The reel 500 is disposed on the second gear 205.

[0065] By setting the first ring 504, when the first gear 203 rotates and meshes with the second gear 205, the second gear 205 will rotate. Since the second shaft 204 is connected to the rotating frame 102, its rotation will have resistance. Therefore, when the second gear 205 rotates, it will idle on the first ring 504 for a certain angle, causing the fourth spring 507 to stretch. After the second limit bar 506 contacts the first limit bar 505, the second gear 205 continues to rotate and can drive the second shaft 204 to rotate, that is, the second gear 205 will idle on the second shaft 204 for a certain angle before driving the second shaft 204 to rotate. During the period when the second gear 205 is idling, it can drive the winding shaft 500 to rotate to lift the position of the second tube 401 upward, so that the position of the nozzle 108 can be moved upward before rotating the second shaft 204 and the rotating frame 102, thereby avoiding interference and spraying on the outer wall of the rotating frame 102.

[0066] As a further embodiment of the present invention, the winding shaft 500 is internally rotatably connected to a second ring 508, which is fixed to the second gear 205. The outer wall of the second ring 508 is provided with a plurality of connecting grooves 509, and a push rod 510 is slidably connected in the connecting groove 509. A fifth spring 511 is connected between the push rod 510 and the connecting groove 509. The inner wall of the winding shaft 500 is provided with a slot 512 adapted to the push rod 510, and one end of the push rod 510 and the slot 512 are sleeved in a semi-spherical shape.

[0067] By setting the top rod 510, in the initial state, the top rod 510 can be sleeved with the card slot 512 by the force of the fifth spring 511, and there is a certain friction between the top rod 510 and the card slot 512. When the second gear 205 rotates, it can drive the second ring 508 to rotate. The rotation of the second ring 508 can rotate the reel 500 through the friction between the top rod 510 and the card slot 512. When the reel 500 rotates and uses the traction rope 503 to move the second tube 401 upward, the second tube 401 moves and compresses the third spring 402 to the limit, and the resistance to the rotation of the reel 500 increases to the limit. At this time, when the second gear 205 continues to rotate to allow the second shaft 204 to rotate, the top rod 510 is compressed by the card slot 512 and can be retracted in the connecting groove 509, that is, the second ring 508 idles in the winding shaft 500, which can avoid the second shaft 204 from rotating in a difficult position due to position restrictions after the second tube 401 and the connecting rod 501 move to the extreme position. Furthermore, limiting the upward movement distance of the second tube 401 can avoid the nozzle 108 from leaving a higher position of the rotating frame 102, resulting in the problem of part of the powder being sprayed on the outside when the nozzle 108 is working later.

[0068] As a further solution of the present invention, the first tube 400 extends to the top of the spray box 107 and is connected to a closed tube 403. The second tube 401 extends into the closed tube 403. The outer wall of the second tube 401 is provided with multiple communication ports 404.

[0069] By providing the connecting port 404, in the initial state, the powder can enter the second tube 401 through the gap between the closed tube 403 and the first tube 400 and the connecting port 404. When the traction rope 503 pulls the connecting rod 501 to allow the second tube 401 to move upward, the connecting port 404 can enter the closed tube 403, and the connecting port 404 is closed by the closed tube 403 to prevent the powder from continuing to enter. During the rising process of the second tube 401 and the nozzle 108, when the nozzle 108 has not completely left the rotating frame 102, the residual powder in the second tube 401 can continue to be sprayed out by the nozzle 108, but there is no new powder supply. After the nozzle 108 completely leaves the rotating frame 102, the powder in the second tube 401 is completely sprayed out, so that the powder spraying can be stopped when the nozzle 108 is moved to a preset distance, thereby avoiding the problem of invalid spraying.

[0070] As a further solution of the present invention, a baffle plate 109 is rotatably connected to the discharge port 106;

[0071] By providing the material blocking plate 109 , a buckle can be provided between the material blocking plate 109 and the connecting frame 101 to ensure that the discharge port 106 is closed during the spraying process.

[0072] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
