It should also be understood that terms defined in general dictionaries should be interpreted to have meanings consistent with their meanings in the context of the relevant art, and should not be interpreted in an idealized or excessively formalized sense, unless specifically defined here.

[0029] Techniques, methods, and devices known to those of ordinary skill in the relevant art can not be discussed in detail, but where appropriate, the techniques, methods, and devices should be considered as part of the specification.

[0030] As shown in Figures 1 to 4 The technical scheme of some embodiments provides a liquid crystal substrate glass measuring device, which comprises a base assembly 10, a friction-reducing positioning support assembly 20, and a dial gauge assembly 30. The base assembly 10 comprises a base structure 11 and a contact protruding structure 12, and the contact protruding structure 12 is arranged on the first side of the base structure 11. The friction-reducing positioning support assembly 20 is arranged on the first side of the base structure 11 and at the bottom of the base structure 11. The dial gauge assembly 30 is movably arranged on the side of the base structure 11 away from the liquid crystal substrate glass.

[0031] When the liquid crystal substrate glass moves from one side of the base structure 11 to the direction close to the dial gauge assembly 30, the friction-reducing positioning and supporting assembly 20 plays a triple role of reducing friction, positioning and supporting, so that the friction between the liquid crystal substrate glass and the liquid crystal substrate glass measuring device is small, thereby greatly reducing the risk of breaking the liquid crystal substrate glass. After the liquid crystal substrate glass is moved to the position, the measurement is performed by cooperation of the friction-reducing positioning and supporting assembly 20 and the dial gauge assembly 30. The technical solution of the above embodiment effectively reduces the problem that the existing liquid crystal substrate glass is easily broken when measuring the right angle.

[0032] As shown in Figure 1 and Figure 3 , in the technical solution of some embodiments, the friction-reducing positioning and supporting assembly 20 includes a mounting rod 21 and a positioning bearing 22, the mounting rod 21 is arranged on the base structure 11 vertically to the plane of the base structure 11, and the positioning bearing 22 is rotatably mounted on the mounting rod 21. The above structure has low cost and is convenient to use. The sliding friction of the prior art is changed to rolling friction, which greatly reduces the friction force on the liquid crystal substrate glass, thereby saving external force. The mounting rod 21 is detachably fixed on the base structure 11, the positioning bearing 22 is in interference fit with the mounting rod 21, and the positioning bearing 22 can be a cylindrical roller bearing, so that the positioning bearing 22 has a certain length in the axial direction, which is more conducive to the cooperation of the side edges of the liquid crystal substrate glass.

[0033] As shown in Figure 1 and Figure 3 , in the technical solution of some embodiments, the friction-reducing positioning and supporting assembly 20 is a plurality of friction-reducing positioning and supporting assemblies 20, and the upper surfaces of the friction-reducing positioning and supporting assemblies 20 are located on the same plane. The structure of the plurality of friction-reducing positioning and supporting assemblies 20 makes the support of the liquid crystal substrate glass more stable. In addition, according to the principle that two points form a line, the plurality of friction-reducing positioning and supporting assemblies 20 are more conducive to positioning in a straight line. It should be noted that the friction-reducing positioning and supporting assembly 20 of some embodiments is two, and the two friction-reducing positioning and supporting assemblies 20 are on the same horizontal plane, and the same inclined plane is also possible.

[0034] As shown in Figure 1 , in the technical solution of some embodiments, the contact convex structure 12 includes a plurality of convex strips, and each convex strip extends along the moving direction of the liquid crystal substrate glass. The contact convex structure 12 can reduce the contact between the surface of the liquid crystal substrate glass and the base assembly 10, and generate friction and wear. The plurality of convex strips can ensure the stability of the contact of the liquid crystal substrate glass, and each convex strip extends along the moving direction of the liquid crystal substrate glass, so that the friction of the liquid crystal substrate glass is smaller when the liquid crystal substrate glass moves.

[0035] As shown in Figure 1 and Figure 2As shown in the technical scheme of some embodiments, the dial gauge assembly 30 comprises a dial gauge, a screw rod and a nut, the base structure 11 comprises a base plate, and the base plate is provided with vertically extending mounting long holes. The dial gauge assembly 30 and the base plate in the above structure are matched to realize the up-down movement adjustment of the dial gauge assembly 30. The above structure enables the liquid crystal substrate glass measuring device to not only realize the perpendicularity measurement of the liquid crystal substrate glass, but also realize the measurement of whether the inclination processing error of the side edge of the liquid crystal substrate glass meets the requirements.

[0036] As shown in the technical scheme of some embodiments, Figure 1 As shown in the technical scheme of some embodiments, the base plate is provided with a plurality of lightening holes. In this way, the weight of the base plate can be reduced, and the material can be saved.

[0037] As shown in the technical scheme of some embodiments, Figure 4 As shown in the technical scheme of some embodiments, the liquid crystal substrate glass measuring device further comprises a mechanical arm assembly 40, the mechanical arm assembly 40 comprises a mechanical arm seat structure 41, a mechanical arm structure 42, a substrate glass pushing structure 43 and a suction cup structure 44, the mechanical arm structure 42 is movably installed on the mechanical arm seat structure 41, the substrate glass pushing structure 43 is installed on the mechanical arm structure 42, and the suction cup structure 44 is movably installed on the mechanical arm structure 42. The suction cup structure 44 of the mechanical arm assembly 40 is used to adsorb and fix the liquid crystal substrate glass, and then the substrate glass pushing structure 43 is used to move the liquid crystal substrate glass to a predetermined position. Such a structure can not only reduce the labor intensity of the operator, but also reduce the risk of injury to the operator, and improve the automation degree of the liquid crystal substrate glass measuring device.

[0038] As shown in the technical scheme of some embodiments, Figure 4 As shown in the technical scheme of some embodiments, the mechanical arm seat structure 41 comprises a seat body and a first sliding groove provided on the seat body, the mechanical arm structure 42 comprises a first mechanical arm, a first motor and a first threaded rod, the first motor is installed on the seat body, the first end of the first mechanical arm is provided in the first sliding groove, the first end of the first mechanical arm is provided with a first threaded hole matched with the first threaded rod, and the axis of the first threaded rod is perpendicular to the base structure 11. The rotation of the first threaded rod is converted into the translation of the first mechanical arm. Such a transmission structure makes the movement of the first mechanical arm more stable, and the cooperation between the first sliding groove and the first end of the first mechanical arm makes the movement precision of the first mechanical arm higher. The first sliding groove in the embodiment is a dovetail groove, and the first end of the first mechanical arm is matched with the dovetail groove. Under the drive of the first motor, the first mechanical arm can move close to and away from the base structure 11.

[0039] As shown in the technical scheme of some embodiments, Figure 4As shown, in some embodiments, the robotic arm structure 42 further includes a second robotic arm and a second motor. The first end of the second robotic arm is rotatably mounted on the second end of the first robotic arm, and the second motor is mounted on the second end of the first robotic arm. The output shaft of the second motor is connected to the first end of the second robotic arm. The second motor ensures that the second robotic arm rotates at a certain angle, which is to adjust the plane of the liquid crystal substrate glass to be parallel to the plane of the suction cup structure 44, thus ensuring the balanced force on the liquid crystal substrate glass.

[0040] like Figure 3 As shown, in some embodiments, the substrate glass pushing structure 43 includes a third motor and a second threaded rod. The suction cup structure 44 includes a suction cup frame and multiple suction cups mounted on the suction cup frame. The third motor is mounted on a second robotic arm, which has a second sliding groove. The suction cup frame is partially movably mounted in the second sliding groove. The suction cup frame has a second threaded hole adapted to the second threaded rod, which passes through the second threaded hole. The output shaft of the second motor is connected to the second threaded rod. The rotation of the second threaded rod is converted into the translation of the suction cup structure 44 by the third motor driving the second threaded rod to rotate. This structure is easy to operate and has low processing costs. It should be noted that the multiple suction cups of the suction cup structure 44 are connected to a negative pressure suction device through an adsorption pipeline. A main valve and branch valves are provided on the negative pressure suction pipeline. The main valve is located on the main branch of the adsorption pipeline, and the branch valves are located on the branches of the adsorption pipeline corresponding to each suction cup.
