DETAILED DESCRIPTION

[0024] See also Figure 1 In an embodiment of the present invention, an online thickness deviation detection device for double-layer insulating glass detection includes a support plate 1, two support plates 1 are arranged in parallel, the opposite sides of the support plates 1 are bonding surfaces, four corners of the bonding surface are respectively provided with electromagnetic suction cups 2, a distance meter 3 is provided at the center of the bonding surface, a cleaning component 4 is provided below the bonding surface, and the side of the support plate 1 away from the bonding surface is a driving surface.

[0025] In this embodiment, gears 5 are rotatably provided at the four corners of the driving surface, and the rotating shaft of each gear 5 passes through the support plate 1 and is eccentrically connected to the corresponding electromagnetic suction cup 2. Racks 6 are embedded on both sides of the driving surface so that they can slide up and down, and the two gears 5 on the same side are meshed with the racks 6 on that side.

[0026] In this embodiment, each of the racks 6 can be driven to slide by a servo telescopic rod 7 fixed on the driving surface. That is, the servo telescopic rod 7 can simultaneously drive the two gears 5 on the side to rotate, thereby driving the corresponding two electromagnetic suction cups 2 to change the direction of the center of the circle, and by controlling the power on and off and direction change of the electromagnetic suction cups 2 corresponding to the two support plates 1, the two support plates 1 can be moved synchronously in the glass, so that the two rangefinders 3 can jointly detect the multi-point thickness.

[0027] See also Figure 2 In this embodiment, the cleaning assembly 4 includes a brush rod 41, and the two brush rods 41 are symmetrically arranged in the fitting surface of the support plate 1. A slide groove 42 penetrating to the driving surface is provided at the lower center of the support plate 1. The slide groove 42 is slidably provided with a slider 44 in the driving surface. One end of the two brush rods 41 passes through the slide groove 42 and is hinged to the slider 44. A connecting rod 43 is also hinged in the middle of each brush rod 41, and the other end of the connecting rod 43 is hinged to the middle of the support plate 1. In other words, the two brush rods 41 can be driven to perform fan-shaped opening and closing movements by sliding the slider 44 to clean the glass surface and prevent debris from affecting the detection results.

[0028] In this embodiment, the distance meter 3 can be slidably penetrated into the driving surface of the support plate 1, and the distance meter 3 is provided with a return spring 33 in the driving surface, and the return spring 33 provides an elastic force to move the distance meter 3 toward the bonding surface until it is bonded to the glass surface. In other words, by bonding two distance meters 3 to the glass surface and measuring the distance between them, the thickness of the glass at this point can be detected.

[0029] In this embodiment, the rangefinder 3 is slidably connected to a slide bar 31 at one end of the driving surface, one end of the slide bar 31 is hinged to the support plate 1, a push rod 32 is hinged to the middle of the slide bar 31, and the push rod 32 is hinged to the slider 44. That is, when the slider 44 slides up and down, the push rod 32 pushes the rangefinder 3 to extend and retract, and when the slider 44 slides down to close the brush rod 41, the rangefinder 3 retracts to the driving surface side to avoid the brush rod 41.

[0030] In this embodiment, push pieces 45 are fixed on both sides of the slider 44, and a guide piece 61 is provided inside the rack 6, and the guide piece 61 is located above the push piece 45. When the rack 6 on one side slides downward, the guide piece 61 pushes the push piece 45, so that the slider 44 slides downward, driving the brush rod 41 to clean the glass surface, and when the rack 6 returns to the top, the slider 44 is reset upward under the action of the reset spring 33, so that the support plate 1 drives the brush rod 41 to open and close when it moves, simplifying the driving structure and reducing the weight of the device.

[0031] In this embodiment, the guide piece 61 is connected to the rack 6 via a torsion spring. When the downward position of the rack 6 exceeds the threshold of the downward movement of the slider 44, the guide piece 61 bends without affecting the rack 6 to continue to move downward.

[0033] S1. When the electromagnetic chuck 2 is powered on, two support plates 1 are symmetrically attached to two sides of the glass. The electromagnetic chucks 2 corresponding to the two support plates 1 have opposite magnetic properties and are mutually adsorbed in the glass. The two electromagnetic chucks 2 corresponding to the same rack 6 on both sides are respectively defined as group A chucks and group B chucks;

[0034] S2, the suction cups of group A are powered off, and the corresponding servo telescopic rod 7 drives the rack 6 to move downward, so that the gear 5 drives the electromagnetic suction cup 2 eccentrically connected thereto to rotate until the center of the circle faces away from the support plate 1, and then the electromagnetic suction cup 2 of group A is powered on;

[0035] S3, the suction cups of group B are powered off, and at the same time, the servo telescopic rods 7 corresponding to the suction cups of group A are moved upward and returned to their positions, driving the support plate 1 to move as a whole toward the suction cups of group A, and then the suction cups of group B are powered on;

[0036] S4. Two distance meters 3 are attached to the glass surface, and the thickness of the glass at that point is detected by the distance between the two distance meters 3.

[0037] Similarly, by replacing the steps of group A suction cups and group B suction cups, the support plate 1 can be moved in another direction, and by adjusting the extension distance of the servo telescopic rod 7, the corresponding group of suction cups can be directed upward or downward, and the support plate 1 can be moved up and down to sequentially detect the thickness of multiple points of the glass.
