[0020] The technical solutions in the present invention will be further described below in conjunction with the drawings and embodiments.

[0021] Embodiment: Referring to Figures 1 - 8 , this application is a cleaning and drying device for automotive parts, including a transport rack 1. A placing plate 2 for placing parts 41 is slidably arranged on the transport rack 1. The side of the parts 41 with more threaded holes 42 is placed upwards. Flushing holes 3 are opened on the placing plate 2. Slide grooves 38 are horizontally opened correspondingly on both sides of the transport rack 1. The placing plate 2 is slidably arranged in the slide grooves 38 on both sides. A first motor 39 is fixedly arranged on the transport rack 1. A first screw 40 is fixedly arranged on the first motor 39. The first screw 40 passes through one of the slide grooves 38 and is threadedly connected to the placing plate 2. Such a setting can effectively support and place the parts 41 through the placing plate 2. By driving the first motor 39, the placing plate 2 can be effectively driven to move horizontally in the two slide grooves 38 on the transport rack 1. Pulleys can also be connected to both sides of the placing plate 2 located in the slide grooves 38 to make the placing plate 2 move smoothly in the two slide grooves 38.

[0022] As Figure 1 and Figure 2As shown in the figure, a cleaning chamber 4 is also provided on the transport rack 1. The placement plate 2 can be moved into the cleaning chamber 4 by the drive of the first motor 39. The cleaning chamber 4 is used to clean the components 41 on the passing placement plate 2. Openings 47 are provided on both sides of the cleaning chamber 4 along the moving direction of the placement plate 2, and baffles 44 driven by cylinders 45 and used to block the water flow are provided on both openings 47. An observation window is provided on the side wall of the cleaning chamber 4, which is convenient for personnel to observe the inside of the cleaning chamber 4.

[0023] As Figure 2 shown, a cleaning assembly is provided in the cleaning chamber 4. The cleaning assembly includes an upper cleaning part, a lower cleaning part and a driving part. The upper cleaning part is used to wash the upper surface of the component 41 from multiple angles. As Figure 3 shown, the upper cleaning part includes a first fixing plate 7, a rotating rod 8 and an upper spray 9. The first fixing plate 7 is horizontally reciprocally slidably arranged in the cleaning chamber 4. The rotating rod 8 is longitudinally rotatably arranged at the bottom of the first fixing plate 7. The upper spray 9 is located below the rotating rod 8 and the nozzles of the upper spray 9 keep downward in the initial position. A connecting rod 10 is fixedly arranged on the rotating rod 8. The connecting rod 10 and the rotating rod 8 are arranged in a "cross" shape. The upper spray 9 is rotatably arranged on the connecting rod 10. A gear 11 is fixedly arranged on the rotating rod 8. Rack teeth 12 used to mesh with the gear 11 are fixedly arranged on the inner side wall of the cleaning chamber 4 on both the left and right sides of the rotating rod 8. A first torsion spring 43 is arranged between the rotating rod 8 and the first fixing plate 7. The first torsion spring 43 is used to keep the upper spray 9 in the initial position when the rotating rod 8 does not rotate. As Figure 3 and Figure 4 shown, corrugated plates 13 with continuous arcs are provided on the inner walls of the two opposite sides of the cleaning chamber 4. The crests and troughs of the two corrugated plates 13 are staggered relative to each other. Fixed frames 14 are fixedly arranged on both sides of the upper spray 9. A roller 15 is rotatably arranged on each fixed frame 14. The two rollers 15 are respectively used to rollingly abut against the crests of the two corrugated plates 13. The diameters of the troughs corresponding to each other on the two corrugated plates 13 can be larger than the diameters of the corresponding crests, so that the upper spray 9 is in the initial state before the roller 15 abuts against the next crest; the diameters of the troughs corresponding to each other on the two corrugated plates 13 can be equal to the diameters of the corresponding crests, so that when the roller 15 finishes abutting against one of the crests, it immediately abuts against the crest on the other corrugated plate 13, enabling the upper spray 9 to continuously perform angle conversion, and the roller 15 will not contact the trough. A second torsion spring 44 is arranged between each connecting rod 10 and the upper spray 9. The second torsion spring 44 is used to keep the spraying direction of the upper spray 9 always downward in the initial state.

[0024] As Figure 2 、 Figure 5 and Figure 6As shown, the lower cleaning assembly is used to rinse the lower surface of the component 41. The lower cleaning member includes a second fixed plate 16, a connecting frame 17 and a lower spray 18. The second fixed plate 16 is horizontally reciprocatingly slidably arranged in the transport frame 1. The connecting frame 17 is fixed on the second fixed plate 16. The lower spray 18 is fixed on the side of the connecting frame 17 away from the second fixed plate 16, and the nozzle of the lower spray 18 is always upward. The driving member is used to make the upper cleaning member and the lower cleaning member move horizontally in the same direction or in the opposite direction. The driving member includes a driving motor 19 and two driving screws 20. Both the cleaning bin 4 and the transport rack 1 are provided with horizontal and elongated driving holes 21. The first fixed plate 7 and the second fixed plate 16 slide through the corresponding driving holes 21 and extend outward. The driving motor 19 is fixed on the outer wall of the cleaning bin 4. The two driving screws 20 are rotatably arranged at the openings of the two driving holes 21 and are threadedly connected to the first fixed plate 7 and the second fixed plate 16. The thread directions of the two driving screws 20 are the same or opposite. A belt transmission group is provided between the output end of the driving motor 19 and the two driving screws 20. The belt transmission group is composed of a pulley and a belt. The pulleys are respectively installed on the driving motor 19 and the two driving screws 20, and a belt is placed between them to complete the synchronous driving rotation of the two driving screws 20. When the threads on the two driving screws 20 are in the same direction, the upper spray 9 and the lower spray 18 move in the same direction. When the threads on the two driving screws 20 are in opposite directions, the upper spray 9 and the lower spray 18 move in opposite directions. The driving motor 19 can rotate forward and reverse.

[0025] like Figure 1 and Figure 2 As shown, a water collection tank 22 is provided inside the transport rack 1 and below the placement plate 2, and a water pump assembly 23 connected to the water collection tank 22 and equipped with a filter device is also provided outside the transport rack 1, and a transport pipe 24 is provided at the water outlet of the water pump assembly 23, one end of the transport pipe 24 extends into the cleaning bin 4 and the transport rack 1 respectively, and a plurality of flexible hoses 25 are provided between the transport pipe 24 and the upper spray 9 and the lower spray 18. This type of water pump assembly 23 with a filter device is a common device in the prior art, and will not be described in detail herein. The hose 25 may be a spring tube, which can transport water without restricting the movement of the upper spray 9 and the lower spray 18.

[0026] like Figure 1 and Figure 2 As shown, a drying chamber 5 is further provided at the side end of the transport rack 1, and the drying chamber 5 is located in the sliding direction of the placement plate 2. A fan 6 for blowing air to the parts 41 on the placement plate 2 is further provided between the cleaning chamber 4 and the drying chamber 5. The fan 6 can effectively blow air to the parts 41 that have passed through the cleaning chamber 4 in advance, and preliminarily dry the excess moisture on the surface of the parts 41. The blowing direction of the fan 6 is from top to bottom; like Figure 1 andFigure 2 As shown, a heat preservation cavity 26 with an open top is provided in the drying bin 5. A number of oil cylinders 27 with their telescopic ends vertically downward are provided at the top of the drying bin 5. A cover plate 28 is fixed on the telescopic ends of the number of oil cylinders 27. A rubber ring is circumferentially fixed at the bottom of the cover plate 28. A sealing groove for abutting against the rubber ring is provided on the heat preservation cavity 26. A loading rack 29 is fixed at the bottom of the cover plate 28. The loading rack 29 rises and falls in the heat preservation cavity 26 with the telescoping of the number of oil cylinders 27. A number of heating pipes 31 are provided in the heat preservation cavity 26. A vacuum hole 32 for communicating with an external vacuum device is also provided in the heat preservation cavity 26. As Figure 7 shown, a loading plate 30 for placing the parts 41 is slidably provided on the loading rack 29. A slide rail is provided on the loading rack 29. The loading plate 30 is slidably arranged on the slide rail. A number of protection blocks 33 are circumferentially wound around the loading plate 30. A drying hole 34 is provided in the loading plate 30. A number of placing rods 35 are fixed in the drying hole 34. A protection net 36 is provided between the number of placing rods 35 and between the number of protection blocks 33. A handle 37 for facilitating the sliding of the loading plate 30 on the loading rack 29 is provided on one side of the loading plate 30. Through the design of the drying hole 34 and the placing rods 35, the air at the bottom of the parts 41 can circulate, facilitating the drying of the whole parts 41.

[0027] Working principle: During operation, first place the parts 41 on the placing plate 2. Drive the first screw rod 40 to rotate through the first motor 39, so that the placing plate 2 passes through the cleaning bin 4 and the blower 6 in turn with the rotation of the first screw rod 40 and moves towards the drying bin 5. After entering the cleaning bin 4, the placing plate 2 will stay between the upper spray 9 and the lower spray 18. The cylinders 45 on both sides will drive the baffles 44 to simultaneously block the opening 47 downward. Then, through the water supply of the water pump assembly 23, water is sprayed out from the nozzles of the upper spray 9 and the lower spray 18. The driving motor 19 and the belt transmission assembly can effectively drive the two driving screw rods 20 to rotate, and at the same time drive the first fixing plate 7 and the second fixing plate 16 to perform horizontal reciprocating movement in the cleaning bin 4. When the first fixing plate 7 is moving, it will drive the upper spray 9 to move at the same time. When the upper spray 9 moves, it will drive the roller 15 to roll and abut against the peak of one of the corrugated plates 13. At this time, it will drive the upper spray 9 to rotate back and forth around the connecting rod 10 as the axis, changing the spraying angle. Through the continuous movement of the first fixing plate 7, the gear 11 on the rotating rod 8 will mesh with the rack 12. The rotating rod 8 is driven to rotate through the gear 11. When the gear 11 meshes with the rack 12, the rollers 15 on both sides do not contact the corrugated plate 13, so that the upper spray 9 rotates left and right around the rotating rod 8 as the axis, further changing the spraying angle; when the lower fixing plate is moving, it will drive the lower spray 18 to move through the connecting frame 17, and then wash the bottom of the parts 41 through the flushing holes 3.

[0028] After the rinsing is completed, the baffle 44 rises with the cylinder 45, and the placing plate 2 further moves under the blower 6 for blowing. At the same time, the operator can pull out the loading plate 30 through the handle 37, and then place the component 41 on the placing plate 2 onto the loading plate 30. This operation method can also be completed by a robotic arm. By pushing the loading plate 30 back, the loading frame 29 and the loading plate 30 are driven into the insulation chamber 26 by the telescopic movement of the oil cylinder 27, heated by a number of heating tubes 31, and the vacuum is extracted by an external vacuum device. After a certain period of time, the vacuum is broken, then the oil cylinder 27 drives the loading frame 29 to rise, and the component 41 is taken out to complete the drying of the component 41.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
