[0025] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0026] Embodiment 1:

[0027] Refer to Figures 1 to 2 , this embodiment discloses a fully automatic protective extraction device for painting, including:

[0028] The connection line 2 of the wheel hub feeding area for wheel hub transportation;

[0029] A wheel hub protection identification component 7 and a multi-axis robot 6 for grasping protection are successively arranged along the transportation direction of the connection line 2 of the wheel hub feeding area; the wheel hub protection identification component 7 and the multi-axis robot 6 are fixed to the ground through a support part;

[0030] The protection guiding part is arranged on one side of the discharging end of the multi-axis robot 6 and is used for transporting the protection;

[0031] The protection cleaning and collection component, and the feeding end of the protection cleaning and collection component is communicated with the discharging end of the protection guiding part.

[0032] During use, when the connecting line 2 of the hub feeding area conveys the hubs that need to be protected into the hub protection identification component 7, the hub protection identification component 7 identifies the protection positions on the hubs and transmits the information to the multi-axis robot 6. When the hub with protection moves out of the hub protection identification component 7, the multi-axis robot 6 picks up the protection and places it on the protection guiding part, and the protection guiding part conveys the protection to the protection cleaning and collection component for cleaning and collection. Compared with the traditional manual method, this device realizes full-automatic picking of the protection, replaces manual labor, and greatly reduces the labor cost.

[0033] In a further optimized solution, the hub protection identification component 7 includes an identification cover body 701. The bottom of the identification cover body 701 is fixedly connected to the support part. The top of the identification cover body 701 is provided with a hub center identification part. One side of the feeding end of the identification cover body 701 is provided with a feeding induction part. One side of the discharging end of the identification cover body 701 is provided with a protection height measurement part.

[0034] In a further optimized solution, the hub center identification part includes a CCD camera 702, and the CCD camera 702 is fixedly connected to the inner side of the top of the identification cover body 701.

[0035] In a further optimized solution, the feeding induction part includes a photoelectric trigger sensor 703, and the photoelectric trigger sensor 703 is fixedly connected to one side of the feeding end of the identification cover body 701.

[0036] In a further optimized solution, the protection height measurement part includes a hub protection height measurement light curtain 704, and the hub protection height measurement light curtain 704 is fixedly connected to one side of the discharging end of the identification cover body 701.

[0037] In a further optimized solution, the support part includes two brackets 1, and the two brackets 1 are respectively arranged on both sides of the connecting line 2 of the hub feeding area. The bottom of the identification cover body 701 is fixedly connected to the tops of the two brackets 1.

[0038] This device realizes the picking of the intermediate protection of the hub by using the functions of the robot, visual recognition, and synchronous tracking. By setting the photoelectric trigger sensor 703 on one side of the feeding end of the identification cover body 701, when the connecting line 2 of the hub feeding area conveys the hub into it, the photoelectric trigger sensor 703 is triggered. Subsequently, the CCD camera 702 takes a picture of the hub to confirm the center of the protection. This process takes 0.5 s. Then, the hub with protection moves out from the discharging end of the identification cover body 701, and the hub protection height measurement light curtain 704 arranged at the discharging end of the identification cover body 701 is used to measure and confirm the hub protection height value, and the protection height value and the center coordinate value are sent to the multi-axis robot 6. After receiving the coordinates, the multi-axis robot 6 starts to track the protection. This process takes 3 - 5 s. The movable end of the multi-axis robot 6 is provided with a gripper, and the gripper is used to grab the protection. After the multi-axis robot 6 grabs the protection and puts it into the protection guiding part, the above process is repeated to grab the next protection.

[0039] The wheel hub protection height measurement light curtain 704 is preferably an online measurement light curtain of the PTM10-12R type. The wheel hub protection height measurement light curtain 704 is a prior art and will not be elaborated here.

[0040] In a further optimized solution, the protection guiding part includes a guiding bracket 5. The guiding bracket 5 is inclined, with the high end of the guiding bracket 5 close to the discharging end of the multi-axis robot 6, and the low end of the guiding bracket 5 communicated with the feeding end of the protection cleaning and collecting assembly. The guiding bracket 5 is fixedly connected to one of the brackets 1.

[0041] In a further optimized solution, the protection cleaning and collecting assembly includes a purging and de-electrostatic dust removal box 4. The feeding end of the purging and de-electrostatic dust removal box 4 is communicated with the low end of the guiding bracket 5, and the discharging end of the purging and de-electrostatic dust removal box 4 is communicated with a protection collecting box 3.

[0042] The protection is placed at the high end of the guiding bracket 5 by the multi-axis robot 6, and the protection slides down along the slope of the guiding bracket 5 to the purging and de-electrostatic dust removal box 4. After the purging and de-electrostatic dust removal box 4 performs de-electrostatic and dust removal treatment on the protection, the clean protection falls into the protection collecting box 3 for next use.

[0043] The working process of the present utility model is as follows:

[0044] The theoretical calculation time is the whole line beat for the multi-axis robot 6 to pick up the protection when the equipment efficiency meets the requirements.

[0045] The beat time for the multi-axis robot 6 to pick up the protection: ≤ 8 seconds per piece.

[0046] 1. After the CCD camera 702 takes a picture, in 1 s (the picture-taking time is not included in the robot's protection picking-up beat), the protection height is detected by the wheel hub protection height measurement light curtain 704, and the data is transmitted to the multi-axis robot 6.

[0047] 2. The multi-axis robot 6 descends to the required height (referring to the height value given by the wheel hub protection height measurement light curtain 704), in 1 s.

[0048] 3. The multi-axis robot 6 runs along the linear direction of the chain according to the center coordinate value given by the CCD camera 702 until the center of the gripper is coincident with the center of the protection (the route calculated from the coordinate points given by the CCD camera 702 and the chain speed), in 3 s.

[0049] 4. The multi-axis robot 6 vertically raises the gripper and simultaneously presses the top of the protection, in 1 s.

[0050] 5. The multi-axis robot 6 places the protection on the guiding bracket 5, in 2 s.

[0051] 6. The multi-axis robot 6 returns to the origin. Meanwhile, the static elimination and dust removal box 4 is purged to clean the dust on the protection, and the dust is conveyed to the protection collection box 3. The time is parallel to the material picking of the multi-axis robot 6, and the time is 1 s.

[0052] 7. An optoelectronic sensor is installed on the gripper of the multi-axis robot 6 to detect the presence or absence of materials. After the action of taking the protective cover, if no material is detected, the system stops and alarms, waiting for manual confirmation and processing.

[0053] Embodiment 2:

[0054] Reference Figure 3 , the difference between this embodiment and Embodiment 1 is that the static elimination and dust removal box 4 for purging includes a dust removal box body 401. At the feeding end of the top of the dust removal box body 401, an inclined feeding guide plate 402 is fixed. The high end of the feeding guide plate 402 is fixedly connected to the inner wall of the top of the dust removal box body 401, and the low end of the feeding guide plate 402 is located inside the dust removal box body 401. An ion static elimination blower 403 is arranged on one side of the feeding guide plate 402. The ion static elimination blower 403 is fixedly connected to the top of the dust removal box body 401. The ion static elimination blower 403 is arranged opposite to the feeding guide plate 402. A guide block 404 is arranged below the ion static elimination blower 403. The guide block 404 is fixedly connected to the inner wall of the middle part of the dust removal box body 401. A slope is arranged on the top of the guide block 404. The high end of the slope is close to the ion static elimination blower 403. An arc-shaped air guide groove 409 is opened at the bottom of the guide block 404. The air inlet end of the arc-shaped air guide groove 409 is communicated with a dust removal fan 405. The dust removal fan 405 is fixedly connected to the inner wall of the middle part of the dust removal box body 401. The air outlet end of the arc-shaped air guide groove 409 is communicated with the feeding end of an inclined sieve plate 407. The inclined sieve plate 407 is inclined. The low end of the inclined sieve plate 407 is communicated with a protection outlet 406. The protection outlet 406 is communicated with the feeding end of the protection collection box 3. The protection outlet 406 is arranged on the side wall of the dust removal box body 401. The discharging end of the inclined sieve plate 407 is communicated with a dust collection bag 408.

[0055] During use, the protection falls onto the guide block 404 along the feeding guide plate 402. The ion static elimination blower 403 arranged on one side of the feeding guide plate 402 blows towards the protection falling along the feeding guide plate 402 to remove the static electricity on the protection, so as to facilitate the separation of dust from the protection. Subsequently, the protection falls along the slope of the guide block 404 towards the air outlet end of the dust removal fan 405. The dust removal fan 405 blows the protection towards the arc-shaped air guide groove 409. The protection falls onto the inclined sieve plate 407 under the action of gravity. The dust removal fan 405 blows away the floating dust on the surface of the protection during the falling process of the protection. The arc-shaped air guide groove 409 guides the air from the horizontal direction to the vertical direction and carries the dust through the inclined sieve plate 407 and flows towards the dust collection bag 408. The air is discharged from the pores of the dust collection bag 408, and the dust is collected into the dust collection bag 408. The protection then slides down along the inclined sieve plate 407 under the action of gravity and moves from the protection outlet 406 to the protection collection box 3.
