[0037] A resistance strip 31 is fixed on the flip frame 4, and a plurality of arc-shaped resistance blocks 32 are fixed on the resistance strip 31. A fifth spring 33 is connected between the resistance rod 7 and the flip frame 4. A gear 34 is fixed to one end of the cleaning roller 10, and the gear 34 is meshed with the rack 12. The cleaning roller 10 is slidably connected to the flip frame 5, and the strip seat 8 is elastically connected to the rack 12 through a sixth spring 35.

[0038] A second rotating rod 17 is fixed on the flip frame 5, and a cover plate 16 is rotatably connected to the second rotating rod 17. A second torsion spring 18 is connected between the second rotating rod 17 and the cover plate 16. A connecting piece 161 is hinged on the cover plate 16, and a movable rod 19 is hinged on the connecting piece 161. The movable rod 19 is slidably connected to the flip frame 5. A resistance frame 20 is fixed on one side of the movable rod 19, and a second resistance rod 201 is resisted on the resistance frame 20. The second resistance rod 201 is elastically connected to the flip frame 4 through a tenth spring 202, and one end of the second resistance rod 201 resists on the rocker 13.

[0039] The adjustment component includes a limit block 500, one end of which is fixed on the rack 12, and the limit block 500 is located below the cleaning seat 11. A first interference wedge 501 is provided on one side of the cleaning seat 11, and the first interference wedge 501 is in contact with a first interference rod 502. One end of the first interference rod 502 is fixedly connected to the clamping bracket 21, and the first interference rod 502 is slidably connected to the flip frame 4.

[0040] A sliding rod 36 is fixed on the flip frame 5 , and the sliding rod 36 is elastically connected to the cleaning seat 11 through an eighth spring 37 .

[0041] When transporting workpieces, refer to Figures 1 - 9, the workpiece is transported to the first conveyor belt 1 through the handling equipment body 3, and the first conveyor belt 1 transports the workpiece. When the turning frame 4 and the first conveyor belt 1 maintain a horizontal state, the workpiece contacts the cleaning seat 11, and the workpiece can slide into the turning frame 4 through the cooperation of the guide bar 23. The servo motor 6 drives the turning frame 5 to rotate on the turning frame 4, which can realize the initial contact between the interference rod 7 and the inclined surface on the interference bar 31. The fifth spring 33 accumulates force, prompting the interference rod 7 to drive the bar seat 8 and the rack 12 to move synchronously, so that the rack 12 and the seesaw 13 conflict with each other. The seesaw 13 is affected by the conflict force and drives the first rotating rod 14 to deflect on the turning frame 5. The first torsion spring 15 accumulates force, and the deflected seesaw 13 conflicts with the clamping bracket 21, prompting the clamping bracket 21 to push the workpiece to move on the cleaning seat 11, so that the two sides of the workpiece are clamped between the guide bar 23 and the clamping bracket 21, so as to avoid shaking when the workpiece is flipped, thereby improving the stability of the workpiece;

[0042] In order to improve the position stability of the cleaning seat 11 when it contacts the workpiece, the position of the cleaning seat 11 is limited by the limit block 500. When the rack 12 moves, the fixed limit block 500 can be driven to move horizontally, thereby releasing the restriction on the cleaning seat 11. During the deflection of the seesaw 13, it also conflicts with the second conflicting rod 201, causing the second conflicting rod 201 to conflict with the conflicting frame 20. The movable rod 19 can drive the cover plate 16 to close through the connecting piece 161. The cover plate 16 rotates on the second rotating rod 17, and the second torsion spring 18 accumulates force. The closing of the cover plate 16 can prevent the workpiece from falling when it is flipped. At the same time, when the clamping bracket 21 clamps the workpiece, it can drive the first conflicting rod 502 to conflict with the first conflicting wedge 501 on one side of the cleaning seat 11, causing the cleaning seat 11 to slide on the sliding rod 36 and contact the surface of the flip frame 5. The eighth spring 37 accumulates force, so that the cleaning seat 11 moves down to below the cleaning roller 10, and the back of the workpiece contacts the surface of the cleaning roller 10.

[0043] When the flip frame 4 continues to rotate, the purpose of intermittent interference between the interference strip 31 and the plurality of arc-shaped interference blocks 32 can be achieved, so that the strip seat 8 can slide on the rack 12, and the fifth spring 33 continues to accumulate force, and the seesaw 13 stops deflecting, so that the strip seat 8 can drive the gear 34 to move. Through the cooperation of the rack 12, the cleaning roller 10 can move back and forth and rotate at the same time, which can reduce the cleaning dead angle, improve the effect of cleaning impurities on the back of the workpiece and the processing quality of the workpiece. When the flip frame 4 flips to a certain angle, the interference strip 31 releases the interference with the arc-shaped interference block 32 and the interference strip 31, and the cover plate 16 returns to its initial state, so that the workpiece can automatically slide along the cover plate 16 to the second conveyor belt 2 for transportation.

[0044] refer to Figure 1The handling equipment body 3 is mainly composed of a mechanical arm and a vacuum suction cup. The position of the vacuum suction cup is adjusted by the mechanical arm, and the workpiece can be transported from the ground to the first conveyor belt 1, which greatly reduces the labor intensity of manual labor.

[0045] The adjustment component includes a first contact piece 504, which is fixed on the cleaning seat 11, and a sliding block 505 is abutted below the first contact piece 504, and the sliding block 505 is elastically connected to the flip frame 4 through a ninth spring 506, and a second contact wedge 507 is fixed on the sliding block 505, and the second contact wedge 507 is abutted against a third contact wedge 503, and the third contact wedge 503 is fixed to the lower end of the movable rod 19.

[0046] The position of the first abutment piece 504 on the cleaning seat 11 can be limited by the sliding block 505. Figure 9 , the cleaning seat 11 can maintain a stable position when it contacts the sliding workpiece. When the cover 16 is closed, the movable rod 19 drives the third contact wedge block 503 to move and contact the second contact wedge block 507. The ninth spring 506 accumulates force, and the sliding block 505 retracts onto the flip frame 4, prompting the second contact wedge block 507 to drive the sliding block 505 to release the limit on the first contact piece 504. At the same time, when the third contact wedge block 503 continues to move, it can push the first contact piece 504 to move downward, prompting the cleaning seat 11 to move below the cleaning roller 10.

[0047] Embodiment 2: This embodiment is an improvement made on the basis of Embodiment 1. For details, please refer to Figures 1 to 10 A first scraper bracket 111 and a second scraper bracket 112 are respectively slidably connected to the cleaning seat 11, a first spring 113 is connected between the first scraper bracket 111 and the cleaning seat 11, a second spring 114 is connected between the second scraper bracket 112 and the cleaning seat 11, a movable plate 115 is slidably connected below the cleaning seat 11, a third spring 117 is connected between the movable plate 115 and the cleaning seat 11, and two resistance blocks 118 are fixed on the movable plate 115, and the two resistance blocks 118 respectively resist the lower ends of the first scraper bracket 111 and the second scraper bracket 112.

[0048] Two extension blocks 119 are disposed on the movable plate 115 , and a push bracket 120 is disposed on one side of the two extension blocks 119 . The push bracket 120 is elastically connected to the flip frame 5 via a fourth spring 116 , and the push bracket 120 is located between two cleaning rollers 10 .

[0049] A rotating shaft 24 is rotatably connected to the flip frame 5 , a third torsion spring 25 is connected between the rotating shaft 24 and the flip frame 5 , the nozzle 9 is fixed on the rotating shaft 24 , a second abutting piece 241 is fixed on the rotating shaft 24 , and a toggle piece 242 is fixed on the movable plate 115 .

[0050] In order to improve the cleaning effect on the back of the workpiece, the cleaning agent is sprayed through the nozzle 9. When the cleaning roller 10 cleans the back of the workpiece, the cleaning roller 10 will absorb the cleaning agent and stains. However, if there is too much liquid inside the cleaning roller 10, the cleaning effect will be affected. The liquid in the cleaning roller 10 needs to be squeezed out. Figures 3 - 10 When the cleaning seat 11 moves downward, the lower end of the pushing bracket 120 can be located between the two extension blocks 119. When the cleaning roller 10 moves toward the direction of the seesaw 13, one end of one of the cleaning rollers 10 can be in conflict with the pushing bracket 120, so that the pushing bracket 120 moves horizontally on the flip frame 5 and pushes one of the extension blocks 119 to move. The third spring 117 accumulates force, causing a conflicting block 118 on the movable plate 115 to conflict with the second scraper bracket 112, causing the second scraper bracket 112 to extend from the cleaning seat 11 and contact the cleaning roller 10. The spring 114 accumulates force, and the sewage can be squeezed out during the rotation of the cleaning roller 10, and the sewage can be discharged through the cleaning seat 11. When the cleaning roller 10 moves in a direction away from the rocker 13, another resistance block 118 on the movable plate 115 can be realized to be in resistance with the first scraper bracket 111, and the first spring 113 accumulates force, so that the first scraper bracket 111 extends to contact with the cleaning roller 10. The sewage can be squeezed out during the rotation of the cleaning roller 10, and the sewage can be discharged through the cleaning seat 11. The sewage can be scraped off according to the rotation direction of the cleaning roller 10, thereby improving the effect of squeezing the sewage out of the cleaning roller 10;

[0051] When the cleaning seat 11 moves downward, refer to Figure 10 The toggle piece 242 is located on one side of the second contact piece 241. When the movable plate 115 moves back and forth horizontally, the toggle piece 242 can come into contact with the second contact piece 241, causing the rotating shaft 24 to rotate. At the same time, the nozzle 9 fixed on the rotating shaft 24 swings. The third torsion spring 25 stores force and releases elastic force, which can increase the spraying range of the detergent and improve the spraying effect.

[0052] Embodiment 3: This embodiment is an improvement made on the basis of Embodiment 1. For details, please refer to Figures 1 to 10 A cleaning bracket 26 is provided between the first scraper bracket 111 and the second scraper bracket 112. The cleaning bracket 26 is elastically connected to the cleaning seat 11 through the eleventh spring 27. A strip contact plate 28 is provided under the cleaning seat 11. The strip contact plate 28 is elastically connected to the flip frame 5 through the twelfth spring 29. An arc-shaped corrugated plate 30 is fixed on the flip frame 4.

[0053] Some impurities will adhere to the surface of the first scraper support 111 and the second scraper support 112 during the water squeezing process, and need to be cleaned to improve the scraping effect. Figures 3 - 8When the opening of the flipping frame 5 faces downward, the arc-shaped corrugated plate 30 fixed on the flipping frame 4 can achieve the purpose of intermittent contact with the strip-shaped contact plate 28. The eleventh spring 27 stores energy reciprocally, causing the strip-shaped contact plate 28 to continuously contact the cleaning support 26, prompting the cleaning support 26 to reciprocate within the cleaning seat 11, and achieving the purpose of cleaning the impurities attached to the surfaces of the first scraper support 111 and the second scraper support 112, improving the effect of the first scraper support 111 and the second scraper support 112 in scraping the sewage on the cleaning roller 10. When the other sides of the first scraper support 111 and the second scraper support 112 retract into the cleaning seat 11, they are scraped by both sides of the cleaning seat 11.

[0054] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes elements inherent to such process, method, article or device.

[0055] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
