Description

Technical Field

[0001] The utility model relates to the field of glass substrate production, and particularly to a device for measuring the straightness angle of a glass substrate. Background Art

[0002] At present, during the production of glass substrates, after edge grinding is completed, spot checks are required on the glass substrates to check the glass size. The substrates need to be removed from the equipment and placed on a marble inspection platform for inspection, such as a device for detecting the actual length, width and straightness angle of a glass substrate with the publication number CN203083489U. Before the G8 generation, manual handling was mainly used. However, with the increase in glass size (G8 generation size 2200x2500), the difficulty of manual handling has increased significantly, and the stability cannot be guaranteed, nor is it safe. In addition, it is also difficult to manually measure such large glass, and large-scale measuring equipment such as coordinate measuring machines is required for inspection, which also increases a lot of costs. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a device for measuring the straightness angle of a glass substrate, which can realize on-line measurement without moving the glass substrate for measurement, reduce manpower and increase reliability.

[0004] The utility model is realized through the following technical solutions:

[0005] A device for measuring the straightness angle of a glass substrate includes a substrate arranged on a frame. The substrate is provided with a rotating device through a lifting structure. A connecting disk is installed at the rotating end of the rotating device. Symmetrically arranged lateral slide rails and symmetrically arranged longitudinal slide rails are arranged on the lifting structure. Lateral mounting plates are slidably arranged on both sides of the lateral slide rails, and longitudinal mounting plates are slidably arranged on the longitudinal slide rails. Two contact sensors are spaced on each lateral mounting plate and each longitudinal mounting plate. Four connecting arms of the connecting disk are respectively hinged with connecting rods, and the lateral mounting plates and the longitudinal mounting plates are respectively hinged with the corresponding connecting rods. A conveying device is further arranged at the upper end of the frame.

[0006] Further, the lifting structure includes a lifting cylinder installed on the substrate. The piston rod of the lifting cylinder is connected with a lifting mounting plate. Two lateral slide rails are arranged on the side mounting frame of the lifting mounting plate, and the lateral mounting plates are slidably installed on the two lateral slide rails. Two longitudinal slide rails are arranged on the longitudinal mounting frame of the lifting mounting plate, and the longitudinal mounting plates are slidably installed on the two longitudinal slide rails. The double-slide rail structure can enhance the stability when the contact sensors move. A guiding component is further arranged between the substrate and the lifting mounting plate.

[0007] Further, the rotating device is a rotating motor. The rotating motor is installed on the lifting mounting plate, and the output end of the rotating motor is connected with the connecting shaft of the connecting disk through a coupling.

[0008] Furthermore, the guiding component includes a guiding rod. One end of the guiding rod is connected to the bottom of the lifting mounting plate, and the other end of the guiding rod passes through the substrate and is slidably connected to the substrate. Limit rings are provided on the guiding rod at the upper and lower ends of the substrate.

[0009] Furthermore, the conveying device is a belt conveyor, and a photoelectric sensor is provided at the end of the belt conveyor.

[0010] Furthermore, the contact sensor is respectively mounted on the lateral mounting plate and the longitudinal mounting plate through a mounting bracket.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. Since the measurement of the glass substrate is intermittent, the present utility model is installed on the glass substrate production line. Usually, the belt conveyor is responsible for transporting the glass substrate during the production process and will not affect the entire production process.

[0013] 2. There is no need to move the glass substrate for measurement, and on-line measurement is realized, reducing manpower and increasing reliability.

[0014] 3. The stability of the production line is increased, and the automation level of the production line is improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The present utility model will be further described below with reference to the accompanying drawings.

[0020] As Figure 1 – Figure 2As shown in the figure, Embodiment 1: A device for measuring the straightness angle of a glass substrate, comprising a substrate 2 provided on a frame. The substrate 2 is installed with a rotating device through a lifting structure. The rotating end of the rotating device is installed with a connecting plate 10. On the lifting structure, there are symmetrically arranged lateral sliding rails 9 and symmetrically arranged longitudinal sliding rails 18. On both sides of the lateral sliding rails 9, there are slidingly arranged lateral mounting plates 12. On the longitudinal sliding rails 18, there are slidingly arranged longitudinal mounting plates 11. On each lateral mounting plate 12 and each longitudinal mounting plate 11, there are two contact sensors 14 arranged at intervals. The four connecting arms of the connecting plate 10 are respectively hinged with connecting rods 16, and the lateral mounting plates 12 and the longitudinal mounting plates 11 are respectively hinged with the corresponding connecting rods 16; there is also a conveying device at the upper end of the frame.

[0021] Embodiment 2: A device for measuring the straightness angle of a glass substrate. The lifting structure includes a lifting cylinder 3 installed on the substrate 2. The piston rod of the lifting cylinder 3 is connected with a lifting mounting plate 6. On the side mounting frame of the lifting mounting plate 6, there are two lateral sliding rails 9. The lateral mounting plates 12 are slidably installed on the two lateral sliding rails 9. On the longitudinal mounting frame of the lifting mounting plate 6, there are two longitudinal sliding rails 18. The longitudinal mounting plates 11 are slidably installed on the two longitudinal sliding rails 18. The double-sliding rail structure can enhance the stability of the contact sensor 14 when moving; there is also a guiding component between the substrate 2 and the lifting mounting plate 6; the rotating device is a rotating motor 7, and the rotating motor 7 is installed on the lifting mounting plate 6. The output end of the rotating motor 7 is connected with the connecting shaft of the connecting plate 10 through a coupling 8; the guiding component includes a guiding rod 4. One end of the guiding rod 4 is connected with the bottom of the lifting mounting plate 6, and the other end of the guiding rod 4 passes through the substrate 2 and is slidably connected with the substrate 2. On the guiding rod 4 at the upper end and the lower end of the substrate 2, there are both limit rings 5; the conveying device is a belt conveyor 1, and an optoelectronic sensor 15 is provided at the end of the belt conveyor 1; the contact sensors 14 are respectively installed on the lateral mounting plates 12 and the longitudinal mounting plates 11 through mounting brackets 13, and the others are the same as in Embodiment 1. Each sensor, motor, cylinder, etc. are all controlled by a controller. This is the prior art and will not be elaborated. The height of the contact sensor 14 when rising for measurement is the same as the height of the glass substrate 17 transported on the belt conveyor 1.

[0022] The utility model is installed on a glass substrate production line. Usually, the belt conveyor 1 is responsible for transporting the glass substrate 17 during the production process; at this time, the contact sensor 14 is far away from the transported glass substrate 17 and is located below the glass substrate 17. When it is necessary to measure the glass substrate 17, after the optoelectronic sensor 15 detects that the glass substrate 17 to be measured reaches the specified position, the belt conveyor 1 stops, and the position of the glass substrate 17 is as Figure 3As shown. The lifting cylinder 3 jacks up, and the jacking height is determined by the limit ring 5 installed on the guide rod 4. After reaching the height, the rotating motor 7 drives the connecting disc 10 to rotate through the coupling 8, and then drives each longitudinal mounting plate 11 and each lateral mounting plate 12 to move inwards on their respective slide rails through the connecting rod 16, so that the eight sets of contact sensors 14 contact the glass to measure the edge dimension data of the glass substrate 17 (the specific measurement method is the prior art); after the measurement is completed, the equipment resets.
