[0029] Figure 1 FIG. 1 is a structural diagram of a wheel spraying system provided by an embodiment of the present invention. Figure 1 As shown, the wheel painting system includes: a transmission mechanism 10, a spraying mechanism 20, a detection mechanism 30, and a control mechanism 40. The control mechanism 40 is electrically connected to the transmission mechanism 10, the spraying mechanism 20, and the detection mechanism 30, respectively, and is used to control the operation of the transmission mechanism 10, the spraying mechanism 20, and the detection mechanism 30.

[0030] The control mechanism 40 can be implemented using a programmable logic controller (PLC) to perform logical control of the other mechanisms. The control mechanism 40 can be integrated with a display screen and interactive buttons. Optionally, the control mechanism 40 can also be connected to various external human-computer interaction devices (such as a display, touch screen, keyboard, mouse, etc.) to facilitate user command input and display of relevant information.

[0031] Figure 2 FIG. 1 is a schematic diagram of a wheel spraying system provided by an embodiment of the present invention. Figure 2As shown, the transmission mechanism 10 is used to carry the wheel and drive the wheel to move. Figure 2 The transmission mechanism 10 is divided into a first area 11, a second area 12, a third area 13 and a fourth area 14 in sequence. According to the functional division, the wheel spraying system can include a loading station, a spraying station, a detection station and an unloading station. The first area 11 can correspond to the loading station, and the wheel completes the loading process at the loading station; the second area 12 can correspond to the spraying station, and the wheel is sprayed with a grease coating at the spraying station; the third area 13 can correspond to the detection station, and the wheel detects the thickness of the grease coating at the detection station; the fourth area 14 can correspond to the unloading station, and the wheel completes the unloading process at the unloading station. In this way, the full process of automated transportation of wheels from loading to spraying to detection and finally unloading can be realized.

[0032] In a possible implementation, the transmission mechanism 10 is a complete structure, for example, composed of a transmission belt, and the transmission belt is driven by a variable frequency motor.

[0033] In another possible implementation, the transmission mechanism 10 may include four independent transmission belts, and the first area 11, the second area 12, the third area 13 and the fourth area 14 each correspond to a transmission belt. Figure 2 As shown, the four conveyor belts are arranged in a straight line. Each conveyor belt is driven by a variable frequency motor, and the speed of each conveyor belt is adjustable. This allows independent control of the conveyor belts at different workstations, thus saving resources.

[0034] In one embodiment, Figure 3 FIG is a partial schematic diagram of a transmission belt provided by an embodiment of the present invention. Figure 3 As shown, the conveyor belts corresponding to the first area 11, the second area 12, and the third area 13 are all equipped with photoelectric detection switches 15 and pneumatic double blockers 16. The photoelectric detection switches 15 are used to detect whether the wheels are in place; the pneumatic double blockers 16 are used to limit the wheels when they are in place.

[0035] For example, a photoelectric detection switch 15 can be positioned below the conveyor belt and capable of emitting a photoelectric signal. When the wheel moves to the position corresponding to the photoelectric detection switch 15, the photoelectric signal is blocked by the wheel, indicating that the wheel has reached the position of the photoelectric detection switch 15 and has reached its designated position. At this point, the pneumatic double blocker 16 rises above the conveyor belt to limit the wheel's position. The photoelectric detection switch 15 and the pneumatic double blocker 16 cooperate to prevent the wheel from moving further to the next station.

[0036] It should be noted that in order to ensure that the photoelectric detection switch 15 and the pneumatic double blocker 16 can successfully lock the wheel, the distance between the photoelectric detection switch 15 and the pneumatic double blocker 16 should not be too large. Generally, the distance between the photoelectric detection switch 15 and the pneumatic double blocker 16 is no greater than the product of the transmission line speed of the corresponding conveyor and the first time, which is equal to the time difference between the photoelectric detection switch 15 detecting that the wheel is in place and the pneumatic double blocker 16 rising into place.

[0037] The spraying mechanism is arranged corresponding to the second area 12 , that is, the spraying mechanism is arranged at the spraying station. The spraying mechanism includes: a first execution component 21 , a movement component 22 , a material storage area 23 and a material discarding area 24 .

[0038] Specifically, the storage area 23 has multiple storage positions, each of which is used to place a can of paint. Optionally, each storage position can be provided with a sensor (such as a photoelectric sensor) for detecting whether paint is placed in the storage position. The motion component 22 of the spraying mechanism first lifts the wheel to the first working position, and then the first actuator 21 grabs the paint from any storage position (for example, it can grab the paint from the storage positions where paint is placed in sequence), shakes the paint, and carries it to the first working position to spray the paint on the wheel to form a grease coating. After the spraying is completed, the first actuator 21 places the paint into the waste area 24.

[0039] Furthermore, since the area of ​​the wheel that requires spraying is typically an annular region with a certain radial length (including both the front and back surfaces of the wheel), to ensure more uniform spraying, the present invention utilizes a combination of wheel rotation and radial reciprocating motion of the first actuator 21. Therefore, the motion assembly 22 of the spraying mechanism is also used to control wheel rotation while the first actuator 21 is spraying.

[0040] In one embodiment, the first actuator 21 comprises a multi-degree-of-freedom robotic arm, with a paint gripping device and a paint pressing device mounted on the tool end of the robotic arm. During spraying, the robotic arm reciprocates along a predetermined radial length, which corresponds to the wheel model. For example, the predetermined radial length for a model A wheel is L1; the predetermined radial length for a model B wheel is L2, and so on. The paint gripping device is used to grasp the paint; the paint pressing device controls the pressing and releasing of the paint can.

[0041] It should also be noted that during the process of grabbing the paint and moving it to the first working position, the first actuator 21 shakes the paint, thereby preventing coagulation and sedimentation of the paint in the tank and ensuring a more uniform spray thickness. Specifically, the first actuator 21 shakes the paint at a preset amplitude and frequency, superimposing the linear displacement from the storage level to the first working position, resulting in a sine / cosine-shaped path.

[0042] The detection mechanism is arranged corresponding to the third area 13 , that is, the detection mechanism is arranged at the detection station. The detection mechanism includes: a second execution component 31 and a motion component 22 .

[0043] Specifically, the motion component 22 of the detection mechanism first lifts the wheel to the second working position, and then the second execution component 31 collects the thickness information of the grease coating and sends the thickness information to the control mechanism 40, so that the control mechanism 40 determines whether the grease coating meets the preparation requirements based on the thickness information.

[0044] In one embodiment, the second actuator 31 includes a multi-degree-of-freedom robotic arm and a thickness gauge mounted on a tool end of the robotic arm. To collect grease coating thickness information, the grease coating thickness is randomly measured at a predetermined number of points on both the front and back sides of the wheel.

[0045] For example, the thickness gauge can be driven by a robotic arm to randomly select a preset number of points from the front and back of the wheel and collect the grease coating thickness corresponding to these points.

[0046] As another example, each time the motion component 22 of the detection mechanism controls the wheel to randomly rotate a certain angle, the thickness gauge collects the grease coating thickness corresponding to a point at a fixed collection position until the grease coating thickness corresponding to a preset number of points is collected.

[0047] The purpose of this thickness information is to allow the control mechanism 40 to determine whether the grease coating meets manufacturing requirements. Specifically, the control mechanism 40 can determine whether the grease coating thickness corresponding to each point is within a preset thickness range. If so, the grease coating meets the manufacturing requirements; otherwise, the grease coating does not meet the manufacturing requirements. Optionally, the control mechanism 40 can further determine the uniformity of the grease coating to meet higher manufacturing requirements, which is not specifically limited in this embodiment of the present invention.

[0048] For the situation that grease coating does not meet preparation requirements, its reason may be because thickness gauge breaks down and causes. In order to eliminate this factor, the present invention can also detect thickness gauge.

[0049] In one embodiment, the second actuator 31 further includes a calibration plate corresponding to a calibrated thickness. When the control mechanism 40 determines that the grease coating does not meet the preparation requirements, the thickness gauge collects the current thickness of the calibration plate, so that the control mechanism 40 determines whether the thickness gauge has malfunctioned based on the current thickness and the calibrated thickness. For example, if the control mechanism 40 determines that the current thickness and the calibrated thickness are not equal or the difference is greater than a preset threshold, the thickness gauge is determined to have malfunctioned.

[0050] In one embodiment, the motion assembly 22 includes: a lifting device, a clamping device and a driving device; the lifting device is used to lift the wheel to a corresponding working position; the clamping device is used to clamp the wheel; and the driving device is used to control the rotation of the wheel.

[0051] In one possible implementation, the drive device uses a servo motor. A servo motor is an indirect speed-changing device that uses an auxiliary motor. Because servo motors offer advantages such as speed control and high position accuracy, and can convert voltage signals into torque and speed to drive the controlled object, they can achieve precise control of wheel rotation. However, servo motors are relatively expensive.

[0052] In another possible implementation, the drive device is implemented using a drive motor and an encoder. Drive motors are less expensive than servo motors, but they cannot achieve rotational positioning. Therefore, the present invention incorporates an encoder (such as an incremental encoder or an absolute encoder) to convert angular displacement into an electrical signal, thereby determining the rotation angle of the wheel.

[0053] In one embodiment, the coating mainly comprises molybdenum disulfide.

[0054] In one embodiment, continue to refer to Figure 2 The wheel painting system may further include an openable first housing 50. When closed, the first housing 50 forms a sealed space. The second area 12 and the spraying mechanism are both located within the first housing 50. This prevents toxic spillage and protects the health of production personnel.

[0055] Further, Figure 4 FIG. 1 is a structural diagram of another wheel spraying system provided by an embodiment of the present invention. Figure 2 and Figure 4 It can be seen that the wheel spraying system may further include: a dust removal mechanism 60 , and the control mechanism 40 is electrically connected to the dust removal mechanism 60 .

[0056] The dust removal mechanism 60 includes an adsorption box 61, a fan 62, and a duct 63. The adsorption box 61 is placed inside the first housing 50 and contains adsorption material capable of chemically adsorbing molybdenum disulfide. The fan 62 is located outside the first housing 50 and communicates with the duct 63, which extends into the interior of the first housing 50. The fan 62 and duct 63 work together to physically remove the molybdenum disulfide.

[0057] It should be noted that arranging the fan 62 outside the first box body 50 can meet the explosion-proof requirements of the wheel spraying system and further ensure production safety.

[0058] In one embodiment, continue to refer to Figure 2 and Figure 4The wheel spraying system may further include: a drying mechanism 70 , and the control mechanism 40 is electrically connected to the drying mechanism 70 .

[0059] The drying mechanism 70 is provided in correspondence with the third area 13. After the motion assembly 22 of the detection mechanism elevates the wheel to the second working position, the drying mechanism 70 is used to blow air toward the wheel to dry the grease coating. Optionally, the drying mechanism 70 can also heat the air blowing toward the wheel to further improve drying efficiency.

[0060] Optionally, the wheel painting system may further include an openable and closable second housing 51. The third area 12, the detection mechanism, and the drying mechanism 70 are all located within the second housing 50 to improve drying efficiency. When the second housing 51 is closed, no airtightness requirements are imposed on the space, allowing the fan 62 to remain within the second housing 50 while still meeting the explosion-proof requirements of the wheel painting system.

[0061] Alternatively, after spraying, the first actuator 21 deposits the paint into a discard area 24, meaning one can of paint is sprayed on one wheel. Therefore, a weighing platform can be provided on the discard area 24 to weigh the paint cans and calculate the amount of paint used. If the amount of paint used is too little, the grease coating may not meet preparation requirements. This can be reported to production personnel for early troubleshooting.

[0062] The technical solution of the embodiment of the present invention is to design a wheel spraying system so that the wheel spraying system includes a transmission mechanism, a spraying mechanism, a detection mechanism and a control mechanism, and the control mechanism is electrically connected to the transmission mechanism, the spraying mechanism and the detection mechanism respectively. First, because the transmission mechanism can carry and drive the wheel to move, it can realize the full process of automated transportation of the wheel from loading to spraying to detection and finally unloading. Second, the spraying mechanism includes a first actuator, a motion component, a storage area and a discard area; the storage area has multiple storage positions, and one storage position is used to place a can of paint; after the motion component of the spraying mechanism lifts the wheel to the first working position, the first actuator can grab the paint from any storage position, shake the paint while carrying it to the first working position, and spray it on the wheel to form a grease coating, thereby realizing the automated spraying of the wheel. In addition, when the first actuator is spraying, the motion component of the spraying mechanism can also control the rotation of the wheel, thereby improving the uniformity of the spraying. After the spraying is completed, the first executive component can also place the paint in the waste area, one can at a time, so as to achieve the classification and neat stacking of the spray cans, which is convenient for the subsequent recycling and reuse of the cans. In addition, because the first executive component will shake the paint in the process of grabbing the paint and coming to the first working position, it can avoid the condensation and precipitation of the paint in the can, thereby ensuring a more uniform spraying thickness. Thirdly, the detection mechanism includes a second executive component and a motion component; after the motion component of the detection mechanism lifts the wheel to the second working position, the second executive component is used to collect the thickness information of the grease coating and send the thickness information to the control mechanism, so that the control mechanism can determine whether the grease coating meets the preparation requirements based on the thickness information, thereby realizing the automation and standardization of the spraying effect. Ultimately, the purpose of improving the spraying efficiency and spraying effect is achieved.

[0063] The above specific embodiments do not limit the scope of protection of the present invention. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions may be made based on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention are intended to be included within the scope of protection of the present invention.
