[0047] The utility model provides a cover glass cleaning, glue spraying and drying device, which is used to clean, glue spray and dry glass sheets or quartz sheets that have been cut into sheets. Figure 1-9As shown, in this embodiment, the device includes a machine 001, on which a reflow device 100 capable of reflowing is arranged, and a plurality of fixtures 110 for clamping cover glass are arranged at equal intervals at the outer edge, and the plurality of fixtures 110 follow the reflow device 100 to perform reflow movement, and a feeding device 200 for providing cover glass and a loading robot 300 for placing the cover glass on the fixture 110 are also arranged on the machine 001 around the reflow device 100. , a cleaning device 400 for cleaning the cover glass on the fixture 110, a glue spraying device 500 for spraying protective glue on the cleaned cover glass, and a feeding device 600 for removing the cover glass sprayed on the fixture 110 and transferring it. At the same time, the equipment also includes a drying oven 700 arranged next to the machine 001 and corresponding to the feeding device 600, which is used to receive the sheet transferred by the feeding device 600, and complete the processing of the cover glass after the sheet is dried in the drying oven 700. In this embodiment, the cleaning device 400 can be a flame plasma surface cleaning device 400 in the prior art, and has a cleaning head that can spray plasma flames toward the sheet, thereby cleaning one side of the sheet. The glue spraying device 500 adopts the ultrasonic glue spraying device 500 in the prior art to coat the surface of the cleaned sheet with protective glue. The drying furnace 700 in this embodiment also adopts the tunnel drying furnace 700 in the prior art to dry the sheet coated with protective glue. The loading robot 300 can also adopt the technical solution in the prior art. In this embodiment, a plurality of suction cups are installed on the three-axis module, so that the cover glass located on the feeding device 200 can be sucked and loaded onto the fixture 110. In this embodiment, the fixture 110 includes a supporting plate 111 and a straw 113, wherein the supporting plate 111 is fixedly mounted on the reflux device 100, and is provided with a plurality of holes 112 arranged at equal intervals, the number of the straws 113 matches the number of the holes 112, and a suction head 114 is fixedly mounted on the upper end of the straw 113 and is inserted into the hole 112, and a limiting portion 824115 is formed on the lower side of the suction head 114 to prevent the straw 113 from falling downwardly out of the hole 112, and the lower end of the straw 113 extends downward out of the hole 112 and is connected to an external air source, and a pair of elastic elements 116 are provided on the portion of the straw 113 located on the lower side of the supporting plate 111 to provide downward elastic force to the straw 113, so that the suction head 114 of the straw 113 is located in the hole 112 under the action of the elastic element 116.

[0048] During the processing of the cover glass, the loading robot 300 takes the cover glass sheet off the feeding device 200 and transfers it toward the jig 110. When placing it on the jig 110, an external air source draws air from the suction tube 113, so that negative pressure is formed at the suction head 114, thereby fixing the sheet on the supporting plate 111 to facilitate the cleaning and glue spraying processing of the sheet.

[0049] Through the technical solution provided in this embodiment, thin glass sheets or quartz stone sheets can be reliably positioned and fixed, and the upper surface of the sheets can be easily cleaned and coated with glue.

[0050] In this embodiment, if Figure 2-4 As shown, the supporting plate 111 includes a first plate member 1111 and a second plate member 1112, wherein the first plate member 1111 is fixedly mounted on the reflux device 100, and the hole position 112 is opened on the first plate member 1111; the second plate member 1112 is located on the lower side of the first plate member 1111, and is connected to the lower end of the first plate member 1111 through a plurality of connecting columns 1114. In this embodiment, in order to make the connection between the first plate member 1111 and the second plate member 1112 more secure, there are a plurality of connecting columns 1114, and the two ends of the connecting columns 1114 are respectively connected to the first plate member 1111 and the second plate member 1112, and a plurality of guide holes 1113 corresponding to the hole position 112 are also opened on the second plate member 1112, and the diameter of the guide hole 1113 is smaller than the size of the limiting portion 824115, thereby preventing the straw 113 from falling out of the guide hole 1113. The support plate 111 adopts the above-mentioned technical solution to facilitate the production and processing of the support plate 111, and the processing and assembly methods are simple.

[0051] In this embodiment, the reflux device 100 drives the jig 110 to perform a reflux action, so that the jig 110 and the cover glass loaded thereon flow through the cleaning device 400 and the glue spraying device 500 in sequence, and the cleaning and glue spraying processing of the upper surface of the cover glass are completed. At this time, since the upper surface of the cover glass has been processed, it is not possible to remove the processed cover glass by the same grasping method as the loading robot 300. Figure 5As shown, the unloading device 600 includes a lifting mechanism 120 and an unloading robot 610, wherein the lifting mechanism 120 is arranged below the fixture 110, and is used to push the suction pipe 113 to overcome the elastic force of the elastic element 116 and thus rise upward. During the rising process of the suction pipe 113, the suction head 114 gradually extends out of the hole 112, thereby lifting the cover glass placed on the carrier plate 111, and under the action of the raised suction pipe 113, the cover glass and the carrier plate 111 are separated from each other, and the distance between the two is gradually increased to form a spacing space; the unloading robot 610 includes a three-axis linear module 611 and a mounting beam 612 mounted thereon, the mounting beam 612 is parallel to the fixture 110 corresponding to the unloading device 600, and a plurality of extension rods 613 extending toward the fixture 110 are mounted on the mounting beam 612, and a unloading suction nozzle 614 facing the direction is mounted on the extension rod 613.

[0052] When the processed cover glass is removed from the jig 110, the lifting mechanism 120 pushes all the suction tubes 113 to move upward, thereby lifting the cover glass located on the supporting plate 111 and forming a spacing space between the cover glass and the supporting plate 111. At this time, the three-axis linear module 611 drives the mounting beam 612 to move toward the spacing space and extends the extension rod 613 into the spacing space, so that the unloading suction nozzle 614 can absorb the lower surface of the cover glass without contacting the upper surface of the cover glass that has been cleaned and sprayed.

[0053] The unloading device 600 and the jig 110 provided in this embodiment can stably and reliably position the cover glass, and when the cover glass is removed from the jig 110, the material can be unloaded by adsorbing the lower surface of the cover glass, thereby ensuring that the upper processed surface of the cover glass is not touched, thereby ensuring the cleanliness of the upper surface of the cover glass.

[0054] In this embodiment, the lifting mechanism 120 includes a first cylinder 621 fixedly installed on the machine platform 001 and a lifting plate 622 installed on the piston rod of the first cylinder 621. The lifting plate 622 corresponds to the straws 113, so that when the first cylinder 621 drives the lifting plate 622 to rise, all the straws 113 can be pushed to rise to overcome the elastic force of the elastic element 116.

[0055] During the processing of the cover glass, after the loading robot 300 grabs the cover glass on the feeding device 200, it is installed on the fixture 110 located on the reflux device 100, and the external air source draws air from the suction tube 113, so that the suction head 114 at the end of the suction tube 113 firmly adsorbs the cover glass on the carrier plate 111. When the reflux device 100 drives the fixture 110 and the cover glass to perform reflux movement, the cover glass passes through the cleaning device 400 and the glue spraying device 500 in turn, and the cleaning device 400 and the glue spraying device 500 clean and glue spray the cover glass in turn. When the cover glass moves to the relative position of the unloading device 600, the first cylinder 621 of the lifting mechanism 120 The lifting plate 622 is lifted to push the lower end of the suction tube 113 to push the suction tube 113 upward, so that the cover glass that has been cleaned and sprayed with glue is lifted and a spacing space is formed between the support plate. Driven by the three-axis linear module 611, the extension plate moves toward the spacing space and penetrates into the spacing space, so that the lower surface of the cover glass is adsorbed by the unloading nozzle 614, so that the processed cover glass is removed from the jig 110. In this embodiment, the drying furnace 700 is located on the side corresponding to the unloading device 600. The unloading device 600 places the cover glass sucked on the jig 110 into the drying furnace 700 to dry the cover glass that has been sprayed with glue.

A pushing mechanism 220 for pushing the cover glass located in the chamber 211 upward is arranged on the lower side of the bottom plate 201, which includes a pushing driving device 221 fixedly mounted on the machine platform 001 and a protruding rod 222 mounted on the pushing driving device 221, and the protruding rod 222 is arranged on the pushing driving device 2 21 is driven to extend toward the silo 210, and accordingly, a through hole is opened in the bottom plate 201 and the bottom of the silo for the extension rod 222 to pass through and extend into the interior of the chamber 211, so that the cover glass located in the chamber 211 can be continuously pushed upward, and the cover glass located in the chamber 211 is conveniently pushed toward the opening 212 of the chamber 211, so that the loading robot 300 can absorb the cover glass at the opening 212 of the chamber 211. In this embodiment, the pushing drive device 221 includes a motor and a ball screw connected to the motor, wherein the extension rod 222 is fixedly connected to the nut, so that when the motor drives the screw to rotate, the nut rotates with the screw and drives the extension rod 222 to reciprocate along the axis of the screw.

[0059] In a further improved technical solution, in order to improve the continuity of feeding, at least two material bins 210 are arranged on the bottom plate 201, and the bottom plate 201 is slidably connected to the machine platform 001. A third cylinder 202 connected to the bottom plate 201 is also fixedly installed on the machine platform 001.
