DETAILED DESCRIPTION

[0037] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods.

[0038] like Figure 1-7 As shown, the present invention discloses a panel cleaning device, including a working platform 1, a cleaning component 2, a transfer mechanism 3, a loading and unloading mechanism 4, a feeding platform 5, a code scanning component 71, a tray unloading platform 6, and an identification mechanism 81. The cleaning component 2, the transfer mechanism 3, the loading and unloading mechanism 4, the feeding platform 5, the code scanning component 71, and the identification mechanism 81 are arranged on the working platform 1. The feeding platform 5 includes an online feeding platform 52 and an offline feeding platform 51, which can meet the product cleaning of two modes.

[0039] The product enters the online feeding platform 52 through the upstream equipment conveyor line. The identification mechanism 81 located on the platform bracket 8 above the online feeding platform 52 takes a photo of the product to be cleaned and locates it. The positioning information is transmitted to the product loading mechanism 41. The product loading mechanism 41 moves to the top of the product to be cleaned along the horizontal moving axis 411 according to the positioning information, and rotates to the same position as the product to be cleaned through the fine-adjustable rotating axis 414 between the suction cup lifting axis 412. The product loading mechanism 41 descends through the vacuum suction cups on the four sides, absorbs the product to be cleaned, and then rises again. The product loading mechanism 41 delivers the product to be cleaned to the vacuum adsorption fixture carrier 201 of the cleaning component 2.

[0040] Offline feeding is carried out through an offline feeding platform 51. The offline feeding platform 51 is stacked with products to be cleaned with built-in trays, and one product to be cleaned is placed in one tray. The offline feeding platform 51 is provided with corresponding limit components 511 on both sides that cooperate with the product tray mechanism. The products to be cleaned with trays are placed in the offline feeding platform 51, and the limit components 511 on both sides are clamped inward at the same time to align the products. A lifting mechanism 512 is provided under the offline feeding platform 51, and a position sensor 513 is provided at the place where the offline feeding platform 51 is parallel to the platform plane. When the lifting mechanism 512 drives the products to be cleaned with trays inside to rise to a position parallel to the platform, the position sensor 513 will receive a signal and the lifting mechanism 512 will stop moving. The identification mechanism 81 located on the platform bracket 8 above the offline feeding platform 51 takes a photo to locate the product to be cleaned. The product loading mechanism 41 moves to the top of the product to be cleaned along the horizontal moving axis 411 according to the positioning information, and rotates to the same position as the product to be cleaned through the fine-adjustable rotating axis 414 between the suction cup assembly 413 and the suction cup lifting axis 412. The product loading mechanism 41 descends, and then rises again after adsorbing the product to be cleaned through the vacuum suction cups on the four sides. The product loading mechanism 41 delivers the product to be cleaned to the vacuum adsorption fixture platform 201 of the cleaning component 2. The tray loading and unloading mechanism 42 grabs the empty tray and places it on the tray discharge platform 6 adjacent to the offline feeding platform 51 for stacking. When grabbing the empty tray, in order to prevent the tray from sticking and causing problems such as multiple grabbing, a telescopic clamp 514 is also provided on the offline feeding platform 51 near the platform plane parallel to the platform. Before grabbing the empty pallet, the telescopic clamp 514 extends out and extends into the gap between the two pallets to fix the lower pallet to prevent the pallet from sticking and being carried away together. After grabbing the empty pallet, the telescopic clamp 514 automatically retracts and the lifting mechanism 512 continues to push the pallet upward.

[0041] After the product to be cleaned is placed on the vacuum adsorption fixture carrier 201, the vacuum adsorption fixture carrier 201 carries the product through the slide rail to enter the cleaning component 2 for cleaning, and arrives at the transfer platform 31 after completing the single-sided cleaning work through the ion rod 203, the spray device 209, and the wiper 206 in sequence. The ion rod 203 can quickly remove foreign matter and dust on the surface of the object and perform preliminary product processing. The spray device 209 is arranged in parallel with the wiper 206 in front of the wiper 206. The spray device 209 is tubular, and a plurality of needle-shaped seepage holes 2091 are equidistantly arranged at the lower part. The other end of the spray device 209 opposite to the support plate 202 is provided with a pressurized air pump 2092, and the pressurized air pump 2092 can be pressurized slightly to allow the liquid inside the spray device 209 to leak downward in a more uniform state. Each group of cleaning devices is provided with at least two wipers 206, the one close to the spray device 209 is a wet cleaning wiper 206, and the rest are dry cleaning wipers 206. A fabric 211 for wiping passes under the wiping head 206. When the product to be cleaned passes through the wiping head 206, the wiping head 206 is pressed down by the motor 207 and the cylinder 208 assembly on the support plate 202, and contacts the surface of the product to be cleaned for wiping. The force of the wiping head 206 pressing down can be controlled by the pressure regulating motor 213 provided on the support plate 202.

[0042] Each cleaning assembly 2 has a support plate 202, on which a material unwinding roll 204, a material receiving roll 205 and a plurality of rollers 210 are symmetrically fixed. The fabric 211 used for wiping is unwinded from the material unwinding roll 204, passes through the rollers 210 in an S-shape to the bottom of the first wiping head 206, then goes around the rollers 210 between the wiping heads 206 in an S-shape, passes under the second wiping head 206 again, and repeats this process until it passes the last wiping head 206 and then goes around the rollers 210 in an S-shape to return to the material receiving roll 205. A sensor 212 is provided on the support plate 202 at a position parallel to the first roller 210 under the material unwinding roll 204 to sense whether the fabric 211 passes by. If the fabric 211 is used up, the sensor 212 will not sense the fabric 211 and will alarm to remind you to replace it.

[0043] After the product has been cleaned on one side, the other sides can be cleaned. The product on the transfer platform 31 is sucked by the cleaning components 2 arranged in different directions through the suction cup component 413 of the upper transfer mechanism 3 to complete the cleaning of the other sides.

[0044] After cleaning, the product is transported to the discharging platform 7 by the transfer mechanism 3. The product passes through the barcode scanning component 71 above the discharging platform 7 on the discharging platform 7, and the barcode scanning component 71 scans the product. The product that fails the barcode scanning continues to move forward and is transported to the unqualified product discharging platform. The qualified product discharging platform can be optionally connected to the feed of the back-end detection equipment.

[0045] A removable mobile rack 9 is provided next to the carrier. A plurality of organic solution storage barrels 91 are placed in the mobile rack 9. An air inlet pipe 92 and a discharge pipe 93 are inserted at the upper end of the organic solution storage barrel 91. The plurality of air inlet pipes 92 are connected through an air inlet valve 94 provided on the mobile rack 9. An air inlet switching device is provided in the air inlet valve 94. The discharge pipe 93 is connected to the spraying device 209 to provide the spraying device 209 with organic solution. When there is no organic solution in the organic solution storage barrel 91 being used, the air inlet switching device will switch the air inlet pipe 92 to another organic solution storage barrel 91, and provide feedback through the liquid level detection device in the barrel to notify the replacement of the organic solution storage barrel 91. It is ensured that there is no interruption of organic solution.

[0046] Multiple through holes 11 are set on the table top of the working platform 1 and multiple through holes 11 are set at the same position on the bottom of the corresponding platform. Through the upper and lower through holes 11, the air above the equipment can be pressed downward to prevent the air flow from being serial in the equipment and blowing the dust on the uncleaned products onto the cleaned products to cause pollution.

[0047] The present invention also discloses a panel cleaning method. Based on the above panel cleaning device and host, the cleaning method comprises:

[0048] The host is provided with an offline feeding mode and an online feeding mode. When the identification mechanism 81 identifies that a product is in place on the online feeding platform 52 , the host controls the entry into the online feeding mode, and the product loading mechanism loads the product from the online feeding platform 52 .

[0049] When the recognition mechanism 81 recognizes that the online feeding platform is empty, the host computer controls the offline feeding mode, and the product loading mechanism loads the product from the offline feeding platform 51. In the offline feeding mode, the recognition mechanism 81 recognizes the product on the online feeding platform 52 within a preset time (for example, once every 5 minutes), and if the product is in place, the offline feeding mode is switched to the online feeding mode, that is, the mode is automatically switched when the product is in place.

[0050] The product enters the working platform 1 from the online feeding platform 52 or the offline feeding platform 51, and the cleaning component 2 cleans the product and then discharges it from the discharging platform. In the offline feeding mode, a tray containing the product is placed on the offline feeding platform, and the tray enters the working platform 1. After the cleaning component 2 cleans the product, the tray loading and unloading mechanism places the tray on the tray discharging platform 6, and the product is discharged from the discharging platform.

[0051] The present invention discloses a panel cleaning device in which online and offline feeding can be freely combined, and multiple modes such as online feeding alone, offline feeding alone, or cross-feeding can be performed according to feedback from an empty load sensor 212. The products of online feeding and offline feeding can be the same or different, and the material flow is divided by the back-end code scanning component 71.

[0052] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes in form and details may be made to the present invention without departing from the spirit and scope of the invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
