Description

Technical Field

[0001] The present invention relates to a wheel processing device, belonging to the technical field of component processing. Background Art

[0002] Wheels are usually installed at the bottom of an object, which is beneficial to reducing the friction coefficient with the contact surface when pulling. With the research and development of wheel structures, most of the currently used wheels are coated with a rubber surface by an injection molding process on the basis of a wheel core to improve their durability and friction resistance. During the preparation process, since the injection molding process will form redundant rubber edges around the shaft hole of the wheel core, they need to be cut off. In addition, for the processing of casters, it usually also includes frequently painting the casters. The painting process is divided into painting the whole workpiece or painting a part of the workpiece. When it is necessary to paint the front and back sides of the workpiece respectively, or when local painting is required, the direction of the spray gun or the position of the workpiece needs to be adjusted. However, in the prior art, both cutting and painting need to be carried out manually. The caster is manually placed at the cutting station, and a machine is used for cutting, or directly manually cut; painting is completed in the form of holding a spray gun by hand. This method is only applicable to labor-intensive regions, but its labor cost is relatively high, and the painting quality is uneven, affecting the use. The production line processing line cannot be completely separated from manual monitoring, and it is necessary to check the situation of the processing line in a timely manner. For the manual operation mode, the efficiency is low, the working environment is poor, and the labor intensity is high. Therefore, it is necessary to make a fully automated improvement for the processing of casters or similar circular workpieces. Summary of the Invention

[0039] The blowing end of the air pipe 150 is arranged between the driving rotating shaft 131 and the first workbench 140; the blowing direction of the air pipe 150 is from the first workbench 140 to the outside of the first workbench 140;

[0040] More specifically, the cutter 110 includes, but is not limited to, a cutting knife.

[0041] Refer to Figure 1 And in combination with Figure 3 , the painting assembly 200 includes a first partition 210, a first sprayer 220, a third vertical cylinder 230, a second workbench 240, and a water curtain 250;

[0042] The first partition 210 is arranged above the second workbench 240;

[0043] The first sprayer 220 is fixedly connected to the first partition 210;

[0044] The output shaft of the third vertical cylinder 230 is fixedly connected to the first partition 210. The third vertical cylinder 230 drives the first partition 210 to reciprocate in the vertical direction;

[0045] A first partition plate 210 is provided with a first opening 211; the injection port of the first injector 220 faces the first opening 211;

[0046] The water curtain 250 includes at least three water flow planes 251, the three water flow planes 251 are connected in sequence and are arranged around the second workbench 240; at least one water flow plane 251 faces the injection direction of the first injector 220.

[0047] The conveyor 300 reciprocates above the first workbench 140 and above the second workbench 240, and conveys the wheels that have been cut on the first workbench 140 to the second workbench 240.

[0048] The usage method of this embodiment is as follows: the wheel to be cut is placed on the first workbench 140 (the position on the first workbench 140 where the wheel is placed is called the first placement station) in a mechanical (after being conveyed by a conveyor belt and then by a robotic arm or robotic gripper) or manual manner, with the shaft hole concentric with the through hole 141. Then the first workbench 140 rotates by a certain angle so that the wheel is located below the active rotating shaft 131 (the position for cutting is called the cutting station). At the same time, another through hole 141 is exactly located at the first placement station, and another wheel to be cut is placed in the same manner at the first placement station;

[0049] The active rotating shaft 131 is driven by the first vertical cylinder 133 to move downward by a fixed distance, the driven rotating shaft 132 is driven by the second vertical cylinder 134 to move upward by a fixed distance, the end of the driven rotating shaft 132 extends from below the through hole 141 and passes through the through hole 141, both the active rotating shaft 131 and the driven rotating shaft 132 extend into the shaft hole of the wheel, and the conical end is easier to align with and enter the shaft hole to position the wheel, and the driven rotating shaft 132 lifts the wheel away from the first workbench 140; then the active rotating shaft 131 is driven by a motor to rotate, and when rotating, it drives the wheel to rotate at a high speed, and the driven rotating shaft 132 is driven to rotate by the wheel; the first horizontal cylinder 120 drives the cutter 110 to move horizontally close to and abut against the part to be cut. After the wheel rotates to complete the cutting, the output shaft of the first horizontal cylinder 120 contracts and resets, and the active rotating shaft 131 stops rotating; the active rotating shaft 131 and the driven rotating shaft 132 contract and reset, the wheel falls back onto the first workbench 140, and the cut tape loop is blown out of the first workbench 140 by the air pipe 150. The first workbench 140 rotates by a certain angle again, and the wheel that has completed the cutting is located below the conveyor 300 (the conveying station), so that the next wheel to be cut is located at the cutting station, and another through hole 141 is located at the first placement station, and the above processing steps are repeated. The through holes 141 need to be distributed around the center of the first workbench 140, so that the first workbench 140 can generate displacement when rotating.

[0050] The conveyor 300 moves the wheels at the conveying station to the second workbench 240 in a mechanically implemented manner such as clamping, grasping, and translation; the second workbench 240 can be fixed or rotatable. If the second workbench 240 is fixed, the conveyor 300 needs to place the wheels between the second workbench 240 and the first partition 210. If the second workbench 240 can rotate, the conveyor 300 places the wheels at a position around the center of the second workbench 240 (the second placement station). The second workbench 240 rotates by a certain angle so that the wheels are located below the first partition 210 (the first painting station), and the part to be painted corresponds to the first opening 211; the third vertical cylinder 230 drives the first partition 210 to move downward by a fixed distance, approaching the wheels and exposing the painted part from the first opening 211; the first injector 220 is started to spray paint into the first opening 211. After completion, the third vertical cylinder 230 drives the first partition 210 to reset upward, completing the painting step. The wheels are taken out in a mechanical (robotic arm or robotic claw) or manual manner and placed on the work station for the next processing step or collected.

[0051] The function of the water curtain 250 is to wash the paint particles in the air. The water curtain 250 is arranged opposite to the spraying direction of the first injector 220, which can wash the sprayed paint faster and purify the air.

[0052] The working process of the whole wheel processing device, such as the sequence of starting of each driving mechanism and the pause time, etc., can be completed through the controller or manual operation. This part is the prior art.
