[0039] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0040] like Figures 1-13 As shown, a car rear cover cleaning system according to an embodiment of the present invention includes a first automatic conveying and cleaning unit 1 , a rear cover turning machine 2 and a second automatic cleaning unit 3 .

[0041] The first automatic conveying and cleaning unit 1 includes a first conveying device 11, on which a plurality of first conveying units 13 are provided. The first conveying units 13 are used to transport the car rear cover 9. A first cleaning robot 12 is provided on one side of the first conveying device 11 to clean the inner side of the car rear cover 9.

[0042] The rear cover flipping machine 2 is arranged at the output end of the first conveying device 11. The rear cover flipping machine 2 includes a bracket 21, on which a motor 22 and a flipping rod group 23 are installed. The flipping rod group 23 is connected to the motor 22. The flipping rod group 23 includes a rotating shaft 231 and an L-shaped rod 232. The rotating shaft 231 is connected to the motor 22. The first end portion (for example, the right end portion) of the L-shaped rod 232 is fixed on the rotating shaft 231, and the second end portion (for example, the right end portion) of the L-shaped rod 232 is installed with a flipping frame to flip the rear cover 9 of the car.

[0043] The second automatic cleaning unit 3 is arranged downstream of the rear cover flipping machine 2. The second automatic cleaning unit 3 includes a second conveying device 31. The input end of the second conveying device 31 cooperates with the rear cover flipping machine 2, and a plurality of second conveying units 32 are provided on the second conveying device 31. The second conveying unit 32 is used to transport the flipped car rear cover 9. A second cleaning robot 33 is provided on one side of the second conveying device 31 to clean the outer side of the car rear cover 9.

[0044] According to an embodiment of the present invention, a car rear cover cleaning system automatically transports, flips and cleans the car rear cover 9 through a first automatic conveying and cleaning unit 1, a rear cover flipping machine 2 and a second automatic cleaning unit 3, thereby improving the degree of automation of the car rear cover 9 cleaning system, and then improving the cleaning efficiency of the car rear cover system, reducing the labor intensity of operators and reducing labor costs, and fundamentally solving the problem that labor-intensive production activities require too many operators.

[0045] Therefore, a car rear cover cleaning system according to an embodiment of the present invention has the advantages of high automation, high cleaning efficiency, and low labor intensity for staff.

[0046] In order to facilitate the understanding of the present invention, Figure 11 As shown, the rear cover 9 of the automobile is divided into three parts. The part where the rear cover glass is located is the second part 92, the part above the rear cover glass is the first part 91, and the part below the rear cover glass is the third part 93, wherein the first part 91 has a first end 911 (upper end), and the second part 92 has a second end 931 (lower end).

[0047] like Figure 5As shown in FIG6 , the cleaning system further includes an automatic turning unit 4 and a transfer machine 5. The automatic turning unit 4 is arranged downstream of the second automatic cleaning unit 3. The automatic turning unit 4 includes a third conveying device 41, on which a plurality of third conveying units 42 are provided. The transfer machine 5 is arranged below the output end of the second conveying device 31 and below the input end of the third conveying device 41. The transfer machine 5 includes a fourth conveying device 51, on which a lift 52 is fixed. The two lifts 52 are arranged at intervals along the width direction of the fourth conveying device 51, and each lift 52 is fixed with a support plate 54. The support plate 54 is provided on the telescopic rod, and the third conveying unit 53 is fixed on the support plate 54. When the car trunk lid 9 is transported to the output end of the second conveying device 31, the elevator 52 on the transfer machine 5 starts to rise, so that the third conveying unit 42 will drive the car trunk lid 9 to move upward until the car trunk lid 9 is completely separated from the third conveying device 41, and then transported to the input end of the third conveying device 41 through the fourth conveying device 51. The elevator 52 drives the third conveying unit 42 and the car trunk lid 9 to descend, thereby placing the car trunk lid 9 on the third conveying unit 42, and thus transporting the car trunk lid 9 through the third conveying unit 42.

[0048] like Figure 5 As shown, the third transport unit 53 includes two transport blocks 531, and the two transport blocks 531 are arranged on the support plate 54 at intervals along the length direction of the support plate 54, so that the first end 911 of the tailgate 9 and the second end 931 of the tailgate 9 are placed in the V-shaped groove of the transport block 531, thereby the tailgate 9 can be stably placed in the third transport unit 53 for transporting the car tailgate 9.

[0049] like Figure 5 As shown, a second placement groove 532 is provided on the transport block, and the second placement groove 532 is V-shaped. So that the rear cover of the car can be placed in the second placement groove 532.

[0050] like Figure 11 As shown in FIG. 12 , the third conveying device 41 includes a first conveying tray 421 and a second conveying tray 422. The first conveying tray 421 is arranged behind the second conveying tray 422. The first conveying tray 421 is provided with a first placement groove 423. The first end portion 911 of the car tailgate 9 is placed in the first placement groove 423 of the first conveying tray 421, and the second end portion 931 of the car tailgate 9 is placed on the second conveying tray 422. When turning, the second end portion 931 of the car tailgate 9 can slide on the second conveying tray 422, and the first end portion 911 rotates in the groove, so that the car tailgate 9 can be transported smoothly, so that the car tailgate 9 will not fall off the fourth conveying device 51.

[0051] like Figure 7As shown in FIG. 10 , the first conveying unit 13 includes two first support columns 131 and two first support plates 132. The two first support columns 131 and the two first support plates 132 are spaced apart along the length direction of the first conveying device 11. The two first support columns 131 are spaced apart along the width direction of the first conveying device 11, and the two first support plates 132 are spaced apart along the width direction of the first conveying device 11. The first support columns 131 are cylindrical, and the upper ends of the first support columns 131 are provided with inclined surfaces 1311, which can fit more closely with the rear cover 9 of the automobile. The first support plates 132 are provided with V-shaped grooves 1321, thereby allowing the rear cover 9 to be placed more stably in the first conveying unit 13. The first support columns 131 are supported in the groove at the rear light on the outer side of the rear cover 9 of the automobile, and the deflector on the outer side of the first portion 91 can be placed in the V-shaped grooves 1321 of the first support plates 132, further ensuring that the rear cover 9 of the automobile is placed stably in the first conveying unit 13.

[0052] The width direction of the first conveying device 11 is as follows: Figure 2 As shown by arrow B, the length direction of the first conveying device 11 is as follows: Figure 2 As indicated by arrow A.

[0053] like Figure 8 and Figure 10 The second conveying unit 32 shown includes two support plates a321 and two support plates b322. The support plates a321 and b322 are spaced apart along the length direction of the second conveying device 31, the two support plates a321 are spaced apart along the width direction of the second conveying unit 32, and the two support plates b322 are spaced apart along the width direction of the second conveying device 31. V-shaped grooves 1321 are provided on the support plates a321 and b322, so that the first end 911 of the rear cover 9 and the second end 931 of the rear cover 9 can be placed in the V-shaped groove 1321 of the support plate a321 and the V-shaped groove 1321 of the support plate b322 respectively, thereby allowing the rear cover 9 to be stably placed in the second conveying unit 32.

[0054] The width direction of the second conveying device 31 is as follows: Figure 2 As shown by arrow B, the length direction of the second conveying device 31 is as follows: Figure 2 As indicated by arrow A.

[0055] like Figure 4As shown, the flip frame includes two first support rods 233 and two connecting rods 234. The two first support rods 233 are spaced apart along the width direction of the first conveying device 11. The two ends of the connecting rod 234 are respectively fixed on the two first support rods 233, and the connecting rod 234 is connected to the second end of the L-shaped rod 232 (the left end of the L-shaped rod). A first mounting plate 325 is fixed at both ends of each first support rod 233. A suction cup device 326 is fixed to the first mounting plate 325 by bolts, so that the suction cup device 326 can be adsorbed on the outer surface of the car rear cover 9, thereby driving the car cover to flip, so that the car rear cover 9 can flip stably. Before use, the flip frame is driven by the motor 22 and rotated to the bottom of the output end of the first conveying device 11. When the car tailgate 9 is transported to the output end of the first conveying device 11, the car tailgate 9 just reaches above the flip frame, and the motor 22 is started, thereby driving the car tailgate 9 to rotate to the output end of the second conveying device 31. At this time, the car tailgate 9 also just flips over 180°, and the car tailgate 9 just flips over to the second conveying unit 32. At this time, since the gravity of the car tailgate 9 is greater than the suction force of the suction cup 329, the car tailgate 9 will detach from the suction cup 329 and fall onto the second conveying unit 32 of the second conveying device 31, thereby facilitating the second cleaning robot 33 to clean the outer side of the car tailgate 9.

[0056] An arc-shaped through hole 327 is provided on each first mounting plate 325, and the suction cup device 326 includes a second mounting plate 328 and a suction cup 329. The suction cup 329 is fixed on the second mounting plate 328, and the second mounting plate 328 is hinged on the first mounting plate 325. Bolts pass through the arc-shaped through holes 327 to fix the first mounting plate 325 and the second mounting plate 328 together. Loosen the nuts on the bolts, rotate the second mounting plate 328, and the bolts slide in the arc-shaped through holes 327, thereby adjusting the angle between the suction cup 329 and the vertical direction, so that the suction cup 329 can fit more stably with the outer side of the car rear cover 9, so that the suction cup 329 can be more stably adsorbed on the outer side of the car rear cover 9.

[0057] A vertical rod 330 is passed through the second mounting plate 328. A suction cup 329 is fixed to one end of the vertical rod 330. A compression spring 331 is provided between the suction cup 329 and the second mounting plate 328. The compression spring 331 passes through the vertical rod 330. When the rear cover 9 of the vehicle is transported to the tilting frame, inertia will generate a significant impact force, which may cause damage to the vehicle body. Therefore, the compression spring 331 is provided within the suction cup assembly 326 to reduce the inertial impact of the rear cover 9 on the tilting frame.

[0058] like Figure 3As shown, guide rods 10 are provided on both sides of the conveying end of the first conveying device 11. The angle between the guide rods 10 and the horizontal line is 30°-45°. The car tailgate 9 can be placed on the first conveying unit 13 along the guide rods 10, thereby facilitating the placement of the car tailgate 9 on the first conveying device 11.

[0059] The first conveying device 11 and the second conveying device 31 are chain conveyors. Since the first conveying device 11 and the second conveying device 31 need to pass the first cleaning robot 13 and the second cleaning robot 33 and the use environment is harsh, chain conveyors are selected.

[0060] The third conveying device 41 and the fourth conveying device 51 are conveyor belts. Conveyor belts are selected because they have stable transportation, low noise and long service life.

[0061] like Figure 1 As shown in FIG6 , the cleaning system further includes a plurality of first infrared position sensors 6, a second infrared position sensor a7, a second infrared position sensor b8 and a controller. The first infrared position sensor 6 is arranged at the output end and the input end of the first conveying device 11, the output end and the input end of the second conveying device 31, and the output end and the input end of the third conveying device 41. The first infrared position sensor 6 includes a first infrared transmitter and a first infrared receiver. The plurality of first infrared transmitters and the plurality of first infrared receivers are spaced relative to each other on both sides of the output end and the input end of the first conveying device 11, on both sides of the output end and the input end of the second conveying device, and on both sides of the output end and the input end of the third conveying device.

[0062] The second infrared position sensor a7 includes a second infrared transmitter a and a second infrared receiver a, and the second infrared position sensor b8 includes a second infrared transmitter b and a second infrared receiver b. The second infrared transmitter a and the second infrared receiver a are respectively arranged on the front and rear sides of the first conveying device 11, and the second infrared transmitter a is arranged on the left side of the first cleaning robot 12, and the second infrared receiver a is arranged on the right side of the first cleaning robot 12. The second infrared transmitter b and the second infrared receiver b are respectively arranged on the front and rear sides of the second conveying device 31, and the second infrared transmitter b is arranged on the left side of the second cleaning robot 33, and the second infrared receiver b is arranged on the right side of the second cleaning robot 33.

[0063] All infrared position sensors, all conveying devices, elevators 52, motors 22, and all cleaning robots are connected to the controller. When the car rear cover 9 passes the first infrared position sensor 6, the second infrared position sensor a7, and the second infrared position sensor b8, the infrared position sensor transmits a signal to the controller, and the controller controls the corresponding conveying device, elevator 52, motor 22, and the corresponding cleaning robot to start or stop, thereby cleaning the car rear cover 9.

[0064] The cleaning process of the present invention is as follows:

[0065] Step 1: Cleaning the inner side of the car's rear cover 9. With the inner side of the car's rear cover 9 facing upward, the outer side of the third portion 93 of the car's rear cover 9 is transported along the guide rod 10 to the first conveying unit 13, so that the first support column 131 is supported in the groove at the rear light on the outer side of the rear cover, and the deflector on the outer side of the first portion 91 is positioned in the V-shaped groove 1321 of the first support plate 132, thereby stably placing the rear cover in the first conveying unit 13. The first infrared position sensor 6 at the output end of the first conveying unit 13 detects that the car cover has been placed in the first conveying unit 13, and the controller controls the first conveying device 11 to start, thereby causing the first conveying device 11 to drive the car's rear cover 9 to move. When the second infrared position sensor a7 detects that the car's rear cover 9 has been transported to the vicinity of the first cleaning robot 12, the first cleaning robot 12 starts working and cleans the inner side of the car's rear cover 9. After cleaning, the first conveying device 11 transports the car's rear cover 9 to the rear cover turning machine 2.

[0066] Step 2: Clean the outer side of the car's rear cover 9. The rear cover flipping machine 2 is first driven by the motor 22 to rotate the flip frame to the bottom of the output end of the first conveying device 11. When the car's rear cover 9 is transported to the output end of the first conveying device, the car's rear cover 9 just moves onto the flip frame, and the suction cup 329 on the flip frame is adsorbed on the outer side of the car's rear cover 9. At the same time, when the first infrared position sensor 6 at the output end of the first conveying device 11 receives a signal, the motor 22 starts to drive the car's rear cover 9 to flip. When the car's rear cover 9 flips to the output end of the second conveying device 31, since the gravity of the car's rear cover 9 is greater than the suction force of the suction cup 329, the car's rear cover 9 will automatically fall onto the second conveying unit 32 of the second conveying device 31. When the first infrared position sensor 6 at the input end of the second conveying device 31 receives a signal, the controller will control the second conveying device 31 to drive the car's rear cover 9 to move. When b8 receives that the car trunk hood 9 is transported to the vicinity of the second cleaning robot 33, the second cleaning robot 33 starts to work and cleans the outer side of the car trunk hood 9. After cleaning, the car trunk hood 9 is transported to the output end of the second conveying device 31. At this time, the elevator 52 of the transfer machine 5 is set below the output end of the second conveying device 31. When the car trunk hood 9 is transported to the output end of the second conveying device 31, the first infrared position sensor 6 receives the signal of the car trunk hood 9. At this time, the elevator 52 on the transfer machine starts to rise, thereby driving the car trunk hood 9 to move upward together until the car trunk hood 9 is completely separated from the second conveying device 31, and then transported to the input end of the third conveying device 41 through the fourth conveying device 51. The elevator 52 drives the car trunk hood 9 down, thereby placing the car trunk hood 9 on the input end of the third conveying unit 42 of the automatic turning unit 4.

[0067] Step 3: Transporting the rear cover unit. The first end 911 of the car's rear cover 9 is placed in the first placement groove 423 of the first conveyor tray 421, and the second end 931 of the car's rear cover 9 is placed on the second conveyor tray 422.
