Description

Technical Field

[0001] The present invention relates to the technical field of wheel hub light-curing coating, and in particular to wheel hub light-curing coating equipment and a coating process thereof. Background Art

[0002] Photocuring coating refers to the use of a photocuring lamp to irradiate photocuring paint to cure the paint on an object.

A first electrode contact 55 is fixedly provided on the top of the support rod 41, and a second electrode contact 56 is fixedly provided on the top wall of the movable square tube 42. When the first electrode contact 55 and the second electrode contact 56 contact each other, the electromagnet 53 will start; when the electromagnet 53 is started, the opposite side of the electromagnet 53 and the magnet 52 have the same polarity.

[0031] A limit block 60 is fixedly provided on the side of each stop block 48 , a limit slot 61 is provided on the rotating shaft 44 , the limit block 60 can reciprocate in the limit slot 61 , and a limit spring 63 is fixedly provided between the limit slot 61 and the limit block 60 .

[0032] The detection assembly includes a rotating gear 80 fixedly arranged on the rotating shaft 44 , a polished rod 81 fixedly arranged on the mounting seat 40 , and a first rack 82 matched with the rotating gear 80 fixedly arranged on the top of the polished rod 81 .

[0033] The light curing device 3 includes a bracket 601, a plurality of first light curing lamps 610 are fixedly installed on the top of the bracket 601, and a side curing assembly is respectively provided on both sides of the bracket 601 along the width direction of the conveyor belt 1 (the curing assemblies on both sides can be used to light cure the two sides of the hub along the thickness direction); the side curing assembly includes a motor 62 fixedly installed on the bracket 601, and a first sprocket 631 is fixedly installed at the output end of the motor 62. The bracket 601 is also fixedly provided with a first support plate 64 and a second support plate 65. The first support plate 64 is provided with a first circular A first transmission shaft 67 is rotatably mounted in the first circular hole. A second sprocket 94 is fixedly mounted on one end of the first transmission shaft 67, and a second curing light 68 is fixedly mounted on the other end of the first transmission shaft 67.

A transmission chain 74 is connected between the first sprocket 631, the second sprocket 94, and the third sprocket 71. The motor is activated to rotate the first, second, and third sprockets, thereby driving the second and third curing lights to rotate.

[0035] The outer peripheral wall of the rotating shaft 44 and the outer surface of the stop 48 are both provided with a sponge 100. When the rotating gear moves downward to engage with the first gear, the stop does not abut the wheel hub. As a result, the rotating shaft 44 inserted into the center hole of the wheel hub rotates and may slip against the inner wall of the center hole of the wheel hub, causing friction and damage. The sponge 100 can prevent the rotating shaft from rubbing against the wheel hub during rotation, which may cause damage to both.

[0036] A coating process using a wheel hub light-curing coating device, wherein the wheel hub is placed on the clamping device 2, the wheel hub is cured using the light-curing device 3, and the driving device 4 is started to cooperate with the clamping device 2 to rotate the wheel hub.

[0037] The working principle of the present invention includes the following process: after the wheel hub is placed on the rotating shaft 44, the rotating shaft 44 is moved downward by the gravity of the wheel hub. When the rotating shaft 44 moves downward with the movable square tube 42 until the top surface of the movable square tube 42 contacts the top surface of the mounting seat 40, the second electrode contact piece 56 and the first electrode contact piece 55 will contact each other. At this time, the electromagnet 53 will be energized. When energized, the magnet 52 will move toward the direction of the block 48 due to the repulsion of like charges. The magnet 52 will move together with the push column 50 and the conical block 51. At this time, when the conical block 51 contacts the inclined block 49, it will push the inclined block 49 toward the hollow cavity 4. 5 moves outward, the inclined block 49 will bring the abutting block 48 to abut the central hole wall of the wheel hub to achieve clamping of the wheel hub. After clamping, when the conveyor moves the clamping device to the bottom of the driving device, the working hydraulic cylinder 91 is activated, which will move the second rack 92 downward to engage with the rotating gear 80, so that the rotating gear 80 can slowly rotate two circles counterclockwise with the rotating shaft 44 and the wheel hub, so that the arc surface on the lower side and the arc surface on the upper side can be continuously switched in position, so that the entire wheel hub can be fully illuminated by the light curing lamp (i.e., the first, second and third light curing lamps), so that the light curing process is more comprehensive;

[0038] When the wheel hub drives the rotating shaft 44 downward by gravity, the rotating gear 80 on the rotating shaft 44 will mesh with the first rack 82. The meshing of the rotating gear 80 and the first rack 82 will drive the rotating shaft 44 to rotate counterclockwise for one circle, so that it is possible to automatically detect whether the rotating shaft 44 is damaged and cannot rotate without manually adding additional detection steps, thereby avoiding the situation where when the rotating shaft 44 is damaged and cannot rotate, the second rack 92 is moved downward to allow the rotating shaft 44 to rotate counterclockwise, causing the second rack 92 to be damaged due to greater resistance when the rotating shaft 44 cannot rotate. In this way, when placing the wheel hub, only one of the damaged clamping devices needs to be removed and repaired separately, without causing the drive device to be damaged due to the damage of the clamping device, and the hub light curing work on the entire conveyor belt to be stopped during repair, thereby avoiding a significant reduction in work efficiency due to equipment maintenance.

Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
