[0022] Please refer to Figures 1-10 , a double-sided detection device for a glass cover plate of the present invention, comprising a workbench 1. The workbench 1 includes a table body and supporting legs below. Industrial cameras 2 for detection are arranged above and below the workbench 1. The industrial cameras 2 are arranged on support frames. The upper support frame is arranged on the workbench 1. The upper support frame is in an inverted L shape and is arranged on one side of the workbench 1. The lower support frame is arranged on the supporting legs. A through groove 1.1 for placing the glass cover plate is arranged in the middle of the workbench 1. The through groove 1.1 penetrates the upper surface and the lower surface of the workbench 1. Side walls of the through groove 1.1 are formed between the through groove 1.1 and the outer side wall of the workbench 1. Upper sliding grooves 4 and lower sliding grooves 5 are arranged on both side walls of the through groove 1.1. Specifically, a person stands on the side opposite to the upper support frame, with the face facing the left and right sides of the device. The upper sliding grooves 4 and the lower sliding grooves 5 are arranged parallel to each other up and down and penetrate the outer side walls on both sides of the workbench 1. The upper sliding grooves 4 and the lower sliding grooves 5 communicate the through groove 1.1 and the outer side wall of the workbench 1. An adsorption plate 9 and a support plate 10 are respectively slid in the upper sliding grooves 4 and the lower sliding grooves 5. The adsorption plate 9 and the support plate 10 are connected to a driving mechanism. The driving mechanism is arranged on the side wall of the through groove 1.1. The driving mechanism drives the adsorption plate 9 and the support plate 10 to slide in the sliding grooves, so as to realize that the adsorption plate 9 and the support plate 10 extend into the through groove 1.1 or retract into the side wall of the through groove 1.1. An air cavity is arranged inside the adsorption plate 9. The air cavity is connected to an external air suction mechanism through a hose 6. A plurality of air suction holes communicated with the air cavity are arranged on the lower surface of the adsorption plate 9. The air suction mechanism adopts the prior art and will not be elaborated herein.

[0023] When the specific implementation of the present invention is carried out, the cross-section of the through groove 1.1 is larger than the cross-section of the glass cover plate, and the thickness of the glass cover plate is the distance between the adsorption plate 9 and the support plate 10. The driving mechanism can adopt various structures. One is that the driving mechanism includes a motor 7 and a lead screw 11. A set of driving mechanisms are respectively arranged for each adsorption plate 9 and support plate 10. That is, adsorption plates 9, support plates 10, two motors and lead screws 11 are arranged on the side walls on both sides of the through groove 1.1. The motors 7 are arranged on the outer side walls on both sides of the workbench 1. The output shaft of the motor 7 is connected to the lead screw 11. The lead screw 11 is rotatably arranged in the side wall of the through groove 1.1, that is, there is a hole for the lead screw 11 in the side wall. There is a section of groove in the middle of the chute, and the groove communicates with the chute. The length direction of the lead screw 11 is parallel to the sliding direction of the adsorption plate 9 and the support plate 10. Driving plates 12 are arranged on both the adsorption plate 9 and the support plate 10. The driving plates 12 are provided with threaded holes. The adsorption plate 9 and the support plate 10 are threadedly connected to the lead screw 11 through the threaded holes of the driving plates 12. The driving plates 12 move in this section of groove as the lead screw 11 rotates.

[0024] Another structure of the driving mechanism of the present invention is that the driving mechanism includes a motor 7 and a lead screw 11. Cavities are arranged inside the side walls on both sides of the through groove 1.1, that is, side walls are arranged around the cavity. The left and right side walls are provided with chutes, and the chutes communicate with the cavity. The chutes on the left and right side walls form the upper chute 4 or the lower chute 5. When the adsorption plate 9 and the support plate 10 slide in the chute, the lengths of the adsorption plate 9 and the support plate 10 are sufficient to slide in the chutes on the left and right side walls. One motor 7 is arranged on each side. The motor 7 is arranged on the outer side wall of the workbench 1. Two lead screws 11 are rotatably arranged in the cavity on each side. The length direction of the lead screw 11 is parallel to the sliding direction of the adsorption plate 9 and the support plate 10. Driving plates 12 are arranged on both the adsorption plate 9 and the support plate 10. The driving plates 12 are provided with threaded holes.

The rotating shaft 16 is arranged between the upper sliding groove 4 and the lower sliding groove 5 inside the cavity. The length direction of the rotating shaft 16 is perpendicular to the sliding direction of the adsorption plate 9 and the support plate 10. A gear 17 is arranged on the rotating shaft 16. Rack teeth 15 are arranged on the adsorption plate 9 and the support plate 10. The gear 17 meshes with the rack teeth 15. Specifically, the rack teeth 15 are arranged on the lower surface of the adsorption plate 9, and the rack teeth 15 are arranged on the upper surface of the support plate 10. The rack teeth 15 on the adsorption plate 9 are concave in the surface, that is, the adsorption plate 9 on both sides of the rack teeth 15 is higher than the rack teeth 15, which can enable the adsorption plate 9 to slide smoothly in the sliding groove.

[0026] Another structure of the driving mechanism of the present invention is as follows: The driving mechanism includes an upper driving handle 8 and a lower driving handle 18. An upper driving groove 1.2 is arranged on the upper surface of the workbench 1. The upper driving groove 1.2 communicates with the upper sliding groove 4.

The lower driving groove 1.3 communicates with the lower sliding groove 5. The upper end of the lower driving handle 18 is connected to the support plate 10, and the lower end penetrates through the lower driving groove 1.3 and extends below the lower surface of the workbench 1. The adsorption plate 9 and the support plate 10 can be manually slid in the upper driving groove 1.2 and the lower driving groove 1.3 by the upper driving handle 8 and the lower driving handle 18, driving the adsorption plate 9 and the support plate 10 to slide in the sliding groove.

[0027] When the present invention works, first retract the adsorption plate in the upper sliding groove into the side wall of the through groove, and retract the support plate into the through groove. Place the glass cover plate into the through groove, and support it by the support plate in the through groove. Start the industrial camera above the glass cover plate to take pictures and detect the upper surface of the glass cover plate. Then extend the adsorption plate into the through groove, start the air suction mechanism, retract the support plate into the side wall of the through groove, and the air suction mechanism adsorbs the adsorption plate. The industrial camera below the glass cover plate takes pictures and detects the lower surface of the glass cover plate, realizing the double-sided detection of the glass cover plate.

[0028] Finally, it should be noted that the above-described embodiments are only specific embodiments of the present invention, used to illustrate the technical solutions of the present invention, rather than limiting it. The protection scope of the present invention is not limited thereto.
