It should also be noted that the paint sprayed is generally water-soluble paint.

[0045] In an example, Figure 3 and Figure 5 As shown, the painting robot 3 includes a body 31, a mechanical arm 32 and a sprayer 33. The mechanical arm 32 is installed on the body 31 and can perform multi-degree-of-freedom movements. The sprayer 33 is arranged at the end of the mechanical arm 32. The sprayer 33 can achieve multi-angle painting adjustment through the multi-degree-of-freedom movements of the mechanical arm 32.

[0046] Specifically, the fuselage 31, as the basis of the painting robot 3, can provide stable support for the adjustment of the mechanical arm 32 and the execution of the sprayer 33. The mechanical arm 32 can be adjusted with multiple degrees of freedom to change the spraying angle of the sprayer 33, so that the sprayer 33 can spray the hook body 10 at multiple angles to achieve all-round coverage and uniform spraying of the hook body 10.

[0047] Furthermore, the painting robot 3 may also include a walking mechanism, which is arranged at the bottom of the body 31, so that the painting robot 3 has a moving function.

[0048] In an example, Figure 3 and Figure 5 As shown, the robotic arm 32 includes an arm 321, a wrist 322 and a hand 323 connected in sequence, the arm 321 is connected to the fuselage 31 and can at least perform telescopic and rotation adjustments relative to the fuselage 31, the wrist 322 can at least perform rotation, pitch and yaw adjustments relative to the arm 321, and the hand 323 is installed on the wrist 322 and can clamp the sprayer 33 to serve as an actuator.

[0049] Specifically, the function of the arm 321 is to support the wrist 322 and the end effector, and to drive the wrist 322 and the hand 323 to adjust; the wrist 322 is a component connecting the end effector and the arm 321, which has multiple independent degrees of freedom. The wrist 322 adjusts or changes the orientation and spatial posture (direction) so that the end effector can adapt to complex movement requirements; the hand 323 is installed on the wrist 322, imitating a human hand grasping the sprayer 33, so as to act as an end effector to spray paint the hook body 10.

[0050] Furthermore, the painting robot 3 may also include a transmission component 34 mounted on the fuselage 31, and the transmission component 34 may include multiple servo motors and reducers, and the servo motors and reducers cooperate to drive the mechanical arm 32 to adjust multiple degrees of freedom.

[0051] In an example, Figure 1 and Figure 4 As shown, the hook body painting device also includes an atomized paint spraying system 4 and a paint spraying control system 5 connected to the paint spraying robot 3. The atomized paint spraying system 4 is used to provide atomized paint for spraying the hook body 10, and the paint spraying control system 5 is used to automatically control the painting operation process.

[0052] Specifically, the atomized paint spraying system 4 cooperates with the spraying tool 33 so that the painting robot 3 sprays the hook body 10 by atomized paint spraying. The atomized paint spraying system 4 may include a paint supply component, a paint mixing component, a flow controller, an atomizer, an air pressure regulator, etc. It should be noted that the paint supply component needs to have an automatic cleaning function, which can automatically clean the paint pipe and the spraying tool 33 according to the output or production time.

[0053] The spray painting control system 5 can control the entire spray painting process, including four parts: the host computer, the main controller, the sub-controller and the workpiece data acquisition system, and has functions such as air pressure analog control, flow output analog control and gun signal control. Generally, a touch screen can be selected as the host computer, and the main controller and the sub-controller can generally use PLC controllers. For example, the main controller uses the Delta DVP40EH00T2 model, and the sub-controller uses the Delta DVP20EH00R2 model.

[0054] In an example, Figure 2 and Figure 6 As shown, the hook body painting device also includes a paint mist exhaust mechanism 6 arranged in the paint spraying room 1, and the paint mist exhaust mechanism 6 includes an air inlet duct 61 connected to the paint spraying room 1, an exhaust duct 62 connected to the outside of the paint spraying room 1, and a fan 63 located between the air inlet duct 61 and the exhaust duct 62. An activated carbon box 64 and a purification box 65 are provided on the air inlet duct 61 for double filtration.

[0055] Specifically, the paint mist exhaust mechanism 6 adopts the method of sending up and sucking down to ventilate the spray booth 1. The air inlet duct 61 is connected to the lower space of the spray booth 1, and the air outlet of the exhaust duct 62 is set at a certain height (much higher than the spray booth 1), so that the air exhausted from the spray booth 1 can be fully diluted without affecting the air environment around the spray booth 1. And the exhausted air will be filtered through the activated carbon box 64 and the purification box 65. After the activated carbon adsorbs the exhaust gas, the paint mist filtration efficiency can be guaranteed to be not less than 98%, which can meet the national and local comprehensive air pollution emission standards. At the same time, after filtering through the purification box 65, harmful substances can be further reduced to ensure the cleanliness of the air supply. The filter material in the purification box 65 can be imported high-quality filter cotton.

[0056] In an example, Figures 1 to 3 As shown, the conveying mechanism 2 includes a circular track 21 and a conveyor 22. The circular track 21 is erected by a fixed bracket, and part of the circular track 21 is passed through the paint spraying room 1; a hanger 221 for hanging the hook body 10 is provided under the conveyor 22, and the conveyor 22 can run along the circular track 21.

[0057] Specifically, the annular track 21 is erected at a preset height by a fixed bracket, and the fixed bracket can provide stable support for the annular track 21. A portion of the annular track 21 is arranged in the paint spraying room 1, and is sequentially arranged in the paint spraying area 11, the drying area 12 and the air cooling area 13 in the paint spraying room 1, and the other portion of the annular track 21 is arranged outside the paint spraying room 1 to facilitate the loading and unloading operations of the hook body 10. A hanger 221 is provided under the conveyor 22 to suspend the hook body 10. The conveyor 22 is suspended under the annular track 21 and can operate along the annular track 21, that is, the conveyor 22 can carry the hook body 10 to the painting station for painting operations. It should be noted that the annular track 21 can be provided with a limiting mechanism at the painting station, so that the conveyor 22 can be positioned at the painting station with the hook body 10 for painting operations.

[0058] In an example, Figure 2 and Figure 3 As shown, the conveyor 22 is connected to the hanger 221 through a rotating disk 222 at the bottom. The conveyor 22 can drive the rotating disk 222 to rotate around its own axis, and can drive the hook body 10 suspended on the hanger 221 to rotate to adjust the corresponding surface of the hook body 10 and the painting robot 3.

[0059] Specifically, when the painting robot 3 paints the hook body 10, the rotating disk 222 drives the hanger 221 and the hook body 10 to rotate at a constant speed, so that the painting robot 3 can evenly spray the circumference of the hook body 10 to ensure the spraying coverage and improve the spraying quality. The conveyor 22 is also provided with a driving motor that drives the rotating disk 222 to rotate at a constant speed.

[0060] Furthermore, a telescopic mechanism may be provided between the hanger 221 and the conveyor 22 , and the hanger 221 may adjust the height position of the hook body 10 by extending and retracting the telescopic mechanism, so that the painting robot 3 can spray paint.

[0061] In one example, a hanging conveyor chain (not shown in the drawings) is provided on the circular track 21, and the conveyor 22 is provided with a sprocket (not shown in the drawings) matching the hanging conveyor chain, and the conveyor 22 runs on the circular track 21 through the sprocket and the hanging conveyor chain.

[0062] Specifically, the conveyor 22 is suspended on the circular track 21 , and the conveyor 22 can move along the circular track 21 driven by a driving motor through the cooperation of a sprocket and a suspended conveying chain, so as to transport the hook body 10 .

[0063] Furthermore, the transporter 22 may adopt a QXG-3100A heavy-duty suspended conveyor with a single-point lifting capacity of 600kg.

[0064] In an example, Figure 1 and Figure 2As shown, the portion of the annular track 21 outside the paint spraying room 1 is provided with a loading and unloading positioning mechanism 7, which is used to limit the position of the conveyor 22 so that the conveyor 22 can perform loading and unloading operations.

[0065] Specifically, the limiting function of the loading and unloading positioning mechanism 7 prevents the conveyor 22 from moving on the circular track 21, thereby ensuring the safety and reliability of the hook body 10 during the loading and unloading operation. The loading and unloading positioning mechanism 7 can achieve positioning by clamping the front and rear ends of the conveyor 22 in a manner that the feeding cylinder and the clamping cylinder cooperate.

[0066] In an example, Figure 1 and Figure 2 As shown, the hook body painting device also includes a loading and unloading robot 8 arranged corresponding to the loading and unloading positioning mechanism 7 , and the loading and unloading robot 8 is used for hanging or removing the hook body 10 on the hanger 221 .

[0067] Specifically, the loading and unloading robot 8 is used to perform loading and unloading operations of the hook body 10, that is, to remove the painted hook body 10 from the hanger 221 of the conveyor 22, and to hang the hook body 10 to be painted on the hanger 221 of the conveyor 22. The structure of the loading and unloading robot 8 can be the same as that of the painting robot 3, except that the execution program and the function of the hand 323 need to be designed differently, so that the loading and unloading robot 8 can grab or put down the hook body 10.

[0068] In one example, the hook body painting device further includes an electrical control system 9 connected to various electrical devices in the painting room 1, and the electrical control system 9 is used to control the lighting switch, the operation of the fan 63, the fault alarm, etc. in the painting room 1. The electrical control system 9 is controlled by PLC and touch screen, and the PLC synchronously monitors the alarm system and the motor protection system.

[0069] It should be noted that the hook body spray painting device adopts noise reduction and shock prevention measures to ensure that the operating noise of each equipment is less than 85 decibels.

[0070] In order to better understand the present invention, the automatic painting process of the hook body painting device will be further described below in conjunction with the accompanying drawings.

[0071] First, the conveyor 22 runs to the loading and unloading positioning mechanism 7, the loading and unloading positioning mechanism 7 is opened to position the conveyor 22, and the loading and unloading robot 8 performs loading and unloading operations so that the hanger 221 of the conveyor 22 hangs the hook body 10 to be painted, and the loading and unloading positioning mechanism 7 is closed, and the conveyor 22 starts to transport the hook body 10 along the circular track 21.

[0072] The conveyor 22 stops at the painting station in the painting area 11 in the paint spraying room 1, and the hook body 10 is painted by the paint spraying robot 3 in cooperation with the atomizing paint spraying system 4 and the paint spraying control system 5. At the same time, the rotating disk 222 on the conveyor 22 rotates at a uniform speed to cooperate with the paint spraying robot 3 to complete the painting operation.

[0073] After the painting operation is completed, the conveyor 22 continues to run, passes through the drying area 12 and the air cooling area 13 in turn to accelerate drying, and finally moves out of the paint spraying room 1, returns to the loading and unloading positioning mechanism 7, performs the loading and unloading operation again, and starts the automatic painting operation of the next hook body 10, and repeats the operation in this cycle.
