Referring to fig. 1, a cleaning device 10 according to an embodiment of the present invention is used for cleaning a workpiece 20 such as a glass cover plate to remove impurities such as glass powder, dust, moisture, fingerprints, or mold on the surface of the glass cover plate, so as to clean the surface of the glass cover plate.

The longitudinal beam 110 is vertically arranged, one end (lower end) of the longitudinal beam 110 can be fixed on a supporting platform such as a bottom surface, the cross beam 120 is horizontally arranged, one end of the cross beam 120 is connected with the other end (upper end) of the longitudinal beam 110, and the other end of the cross beam 120 is a free end. A guide rail extending along the horizontal direction can be arranged on the cross beam 120, the first slider 130 is in sliding fit with the guide rail extending horizontally, the first driver 150 can be a lead screw driver, a motor of the lead screw driver is fixed on the cross beam 120, a lead screw of the lead screw driver is connected with the first slider 130, and when the lead screw of the lead screw driver rotates, the lead screw can drive the first slider 130 to prop against the cross beam 120 to slide in a reciprocating manner in the horizontal direction; the first slider 130 may be provided with a guide rail extending in a vertical direction, the second slider 140 is in sliding fit with the guide rail extending in the vertical direction, the second driver 160 may also be a lead screw driver, a motor of the lead screw driver is fixed on the first slider 130, a lead screw of the lead screw driver is connected with the second slider 140, when the lead screw of the lead screw driver rotates, the lead screw may drive the second slider 140 to slide in a reciprocating manner in the vertical direction relative to the first slider 130, and of course, the first slider 130 may also drive the second slider 140 to slide in a horizontal direction relative to the cross beam 120.

Referring to fig. 1 and fig. 2, in some embodiments, the material taking mechanism 200 includes a bracket 210 and an adsorbing member 220, the bracket 210 is fixed on the second slider 140, the adsorbing member 220 is connected to the bracket 210, and the adsorbing member 220 is used for adsorbing the workpiece 20. The suction member 220 can be a vacuum suction member, that is, the suction member 220 is connected to a vacuum generator, when the vacuum generator vacuumizes the suction member 220, the suction member 220 will perform a suction action on the workpiece 20, so as to transfer the workpiece 20 from another position to a working platform for cleaning. When the vacuum generator stops the vacuum pumping of the suction member 220, the suction member 220 loses the suction capability to the workpiece 20, so that the workpiece 20 can be placed on the work platform. In the process that the material taking mechanism 200 transfers the workpiece 20 to the working platform, after the adsorbing member 220 absorbs the workpiece 20 at other positions, the second driver 160 drives the second slider 140 to move upward relative to the first slider 130, the first driver 150 drives the first slider 130 to move in the horizontal direction relative to the cross beam 120, so that the workpiece 20 is located right above the working platform, the second driver 160 drives the second slider 140 to move downward relative to the first slider 130, so as to contact the workpiece 20 with the working platform, and finally the vacuum generator stops vacuumizing the adsorbing member 220, so that the workpiece 20 is placed on the working platform, and finally the material taking of the workpiece 20 is realized.

Referring to fig. 1 to 5, in some embodiments, the cleaning mechanism 300 includes a first cleaning member 310, a second cleaning member 320, a mounting frame 330, a sliding member 340, an adjusting member 350, an elastic member 360, and a lifting cylinder 370.

Referring to fig. 4, the mounting frame 330 includes a horizontal plate 331 and two side plates 332, the horizontal plate 331 is disposed horizontally, the side plates 332 are disposed vertically, one of the side plates 332 is connected to one end of the horizontal plate 331, and the other side plate 332 is connected to the other end of the horizontal plate 331, so that the entire mounting frame 330 is formed into a substantially flat-bottomed U-shaped structure. The side plate 332 includes two guide portions 332a arranged at an interval, the guide portions 332a extend in the vertical direction, and a gap 332b is formed between the guide portions 332a, and the gap 332b is elongated and extends in the vertical direction.

Referring to fig. 3 to 5, the sliding member 340 includes a matching portion 341 and two clamping portions 342, one of the clamping portions 342 is connected to one end of the matching portion 341, the other clamping portion 342 is connected to the other end of the matching portion 341, the clamping portions 342 protrude a set length relative to the surface of the matching portion 341, so that the clamping portions 342 and the matching portion 341 surround to form two sliding slots 343 which are oppositely disposed, and the two sliding slots 343 are long and extend in the vertical direction. When the sliding member 340 is disposed on the mounting bracket 330, the engaging portion 341 is engaged with the gap 332b between the guiding portions 332a, that is, the engaging portion 341 is received in the gap 332b, and the guiding portions 332a are engaged with the sliding grooves 343, so that the sliding connection between the sliding member 340 and the mounting bracket 330 is finally achieved. When the sliding member 340 slides relative to the mounting bracket 330, the engaging portion 341 slides in the gap 332b between the guiding portions 332a, the guiding portions 332a slide in the sliding grooves 343, and the sliding member 340 is prevented from shaking during sliding relative to the mounting member by the limiting action of the gap 332b and the sliding grooves 343, so that the sliding reliability and the sliding precision of the sliding member 340 are improved.

The adjusting member 350 may be a bolt, for example, the adjusting member 350 is threadedly coupled to the cross plate 331 of the mounting bracket 330, and a lower end of the adjusting member 350 is abutted against an upper portion of the sliding member 340. The elastic member 360 may be spring-received in the gap 332b between the guide portions 332a, an upper end of the spring abutting against a lower portion of the slider 340, and a lower end of the spring abutting against the mount 330. When the adjusting member 350 is rotated to move downward relative to the mounting frame 330, the adjusting member 350 drives the sliding member 340 to move downward relative to the mounting frame 330, and the elastic member 360 is compressed to store energy. When the adjusting member 350 is rotated to move upward relative to the mounting frame 330, the compression amount of the elastic member 360 is gradually reduced to release energy, and the elastic member 360 drives the sliding member 340 to move upward relative to the mounting frame 330. Therefore, by providing the adjustment member 350 and the elastic member 360, the sliding member 340 can be driven to slide up and down reciprocally with respect to the mounting frame 330.

The cylinder of the lifting cylinder 370 is connected to the base 100, for example, the cylinder of the lifting cylinder 370 may be fixed to the support 210 of the material taking mechanism 200, and the piston rod of the lifting cylinder 370 is connected to the cross plate 331 of the mounting frame 330. When the piston rod of the lifting cylinder 370 extends, the mounting frame 330 can be driven to slide up and down reciprocally relative to the second sliding block 140. Of course, the lifting cylinder 370 may be replaced by a gear mechanism, a link mechanism or a pulley mechanism, which only drives the mounting frame 330 to slide up and down relative to the second slider 140.

Referring to fig. 3 to 5, the first cleaning member 310 includes a first roller 311 and a first rotating shaft 312, the first rotating shaft 312 is disposed on the first roller 311, two ends of the first rotating shaft 312 are rotatably connected to the side plates 332 of the mounting frame 330, the first roller 311 is made of a viscous silicone material, and the viscosity of the first roller 311 is low, that is, the flexibility of the first roller 311 is high. When the first rotating shaft 312 drives the first roller 311 to rotate, the first roller 311 can roll relative to the surface of the workpiece 20, thereby cleaning the surface of the workpiece 20. Since the first roller 311 has a low viscosity and good flexibility, the rolling of the first roller 311 does not leave scratches on the surface of the workpiece 20, thereby preventing the first roller 311 from damaging the workpiece 20.

The second cleaning member 320 includes a second roller 321 and a second rotating shaft 322, the second roller 321 is disposed on the second rotating shaft 322, the second rotating shaft 322 is rotatably connected to the sliding member 340, and the second roller 321 may be made of an adhesive paper material, for example, the adhesive paper material may be a tearable adhesive roll paper, so that the viscosity of the second roller 321 is higher than that of the first roller 311, i.e., the flexibility of the second roller 321 is lower than that of the first roller 311. The second roller 321 is abutted against the first roller 311 above the first roller 311, and when the second rotating shaft 322 drives the second roller 321 to rotate, the second roller 321 rolls on the surface of the first roller 311, so that impurities on the first roller 311 are cleaned, the impurities on the first roller 311 are prevented from forming secondary pollution on the workpiece 20, and the cleanliness of the surface of the workpiece 20 is further improved. In other words, when the first roller 311 rolls relative to the workpiece 20 to clean the workpiece 20, the second roller 321 also rolls relative to the first roller 311 to clean the first roller 311, thereby effectively preventing the dirty substance on the first roller 311 from secondarily contaminating the workpiece 20. Meanwhile, when the adjusting member 350 drives the sliding member 340 to slide up and down relative to the mounting frame 330, the second rotating shaft 322 can drive the second roller 321 to slightly approach or separate from the first roller 311, i.e., the pressure of the second roller 321 against the first roller 311 is adjusted, so as to ensure different cleaning effects of the second roller 321 against the first roller 311. The diameter of the second roller 321 may be greater than or equal to the diameter of the first roller 311, for example, the diameter of the second roller 321 may be greater than twice the diameter of the first roller 311. Since the diameter of the second roller 321 is relatively large, a large surface area of the second roller 321 can be ensured, and the large surface area can further improve the cleaning effect of the first roller 311.

When the cleaning device 10 works, after the material taking mechanism 200 places the workpiece 20 on the working platform, the second driver 160 drives the second slider 140 to move upward relative to the first slider 130, so that the adsorbing member 220 is away from the workpiece 20 by a certain distance, thereby avoiding interference of the adsorbing member 220 in a subsequent cleaning process, then the lifting cylinder 370 drives the mounting frame 330 to move downward, so that the first roller 311 contacts the workpiece 20, meanwhile, the first driver 150 drives the first slider 130 to slide, so that the mounting frame 330 slides in a horizontal direction, further enabling the first roller 311 to roll relative to the workpiece 20, thereby performing all-directional cleaning on different parts of the workpiece 20, meanwhile, the second roller 321 rolls relative to the first roller 311 to clean the first roller 311, and unclean substances on the first roller 311 are removed to avoid secondary pollution to the workpiece 20.

With the conventional cleaning device 10, the material taking mechanism 200 is separately arranged, which reduces the cleaning efficiency of the whole cleaning device 10 for a single workpiece 20, so that the cleaning device 10 lowers the working cycle of the whole production line, and the separately arranged material taking mechanism 200 increases the occupied space and the manufacturing cost of the device. Moreover, the conventional cleaning device 10 directly uses a roller with high viscosity to clean the workpiece 20, the roller with high viscosity may scratch the surface of the workpiece 20 and damage the workpiece 20, and the dirty substance on the roller may cause secondary pollution to the workpiece 20, which affects the cleaning effect of the workpiece 20.

For the cleaning device 10 of the above embodiment, since the material taking mechanism 200 and the cleaning mechanism 300 are integrated on the same base 100, when the second slider 140 moves relative to the first slider 130, the material taking mechanism 200 and the cleaning mechanism 300 can move simultaneously, which can improve the cleaning efficiency of the workpiece 20, further improve the working cycle of the flow production line, and also save the occupied space and the manufacturing cost of the material taking mechanism 200. The viscosity of the first roller 311 is low, so that the first roller 311 is effectively prevented from scratching the workpiece 20, and the workpiece 20 is prevented from being damaged. Meanwhile, the second roller 321 cleans the first roller 311, so that the first roller 311 is prevented from secondarily polluting the workpiece 20, and the cleanliness of the surface of the workpiece 20 is further improved.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
