Description

Technical Field

[0001] The utility model belongs to the technical field of glass substrate detection and relates to an improved glass clamping device and a substrate glass sampling vehicle equipped with the device. Background Art

[0002] Substrate glass plays a crucial role in electronic products, particularly in the manufacture of thin film transistor-liquid crystal displays (TFT-LCDs). With the continuous advancement of electronic technology, TFT-LCDs are increasingly being used in a wide range of electronic products. TFT-LCD displays are typically manufactured using TFT-LCD substrate glass. As a defect-free glass, TFT-LCD substrate glass is a fundamental component of liquid crystal display devices and a key foundational material in the flat panel display industry. The surface flatness, optical properties, thermal stability, chemical stability, dimensional accuracy, alkali-free metal oxide content, and physical properties of TFT-LCD substrate glass all have a significant impact on display performance. TFT-LCD substrate glass requires an extremely flat surface to ensure uniform distribution of the liquid crystal layer on the substrate, thereby ensuring uniformity and clarity of the displayed image. The optical properties of TFT-LCD substrate glass, such as transmittance and refractive index, directly impact the display quality of the LCD.

[0003] Currently, the substrate glass and cover glass industries commonly use sampling carts to extract glass substrates from the normal production process for quality inspection. The typical method for extracting and inspecting glass substrates is as follows: ① The sampling robot places the glass substrate on the sampling cart; ② The sampling cart is pulled into a darkroom; ③ The glass plate is pulled until it aligns with the bottom edge of the sampling cart; ④ The sampling cart is flipped over; ⑤ The substrate glass is quality inspected; ⑥ The sampling cart is returned to a position parallel to the ground; ⑦ The glass substrate is pulled to the other side of the sampling cart; ⑧ The sampling cart is flipped over to inspect the other half of the glass substrate.

[0004] During glass substrate inspection, the existing transport rack must flip from a horizontal to an inclined position after loading the glass. This can cause the glass to slip on the rack and strike the edge of the rack, causing damage. Furthermore, when inspecting the glass substrate's quality on the sampling cart, the vehicle must flip the glass twice, pulling the glass substrate to fit the cart's edge twice to prevent breakage. This type of flipping is difficult to perform and can easily lead to wasted manpower and resources on the production line. Utility Model Content

[0005] In order to overcome the shortcomings of the above-mentioned prior art, the purpose of the present utility model is to provide a device that can reduce the sliding of substrate glass on the transport rack when detecting substrate glass, reduce the collision of substrate glass with the bottom edge of the transport rack of the sampling vehicle, thereby reducing the detection loss of substrate glass and reducing the manpower required to stabilize the substrate glass.

[0006] In order to achieve the above technical objectives, the present invention is implemented through the following technical solutions:

[0007] The utility model discloses a glass clamping device for a substrate glass sampling vehicle, comprising a bracket, a rotating arm and a clamping pad; the rotating arm comprises an upper rotating arm and a lower rotating arm arranged in parallel, and the upper rotating arm and the lower rotating arm are arranged in an "F" shape with the bracket; the clamping pad comprises an upper clamping pad and a lower clamping pad, the upper clamping pad is arranged on the lower side of the upper rotating arm, and the lower clamping pad is arranged on the upper side of the lower rotating arm at a position corresponding to the upper clamping pad, a 90° hinge is fixed on the bracket, and the bracket rotates around the 90° hinge as an axis.

[0008] In one embodiment, the upper arm of the rotating arm has a through hole, the through hole is provided with an internal thread, and the through hole cooperates with the fastening bolt; the lower end of the fastening bolt is fixedly connected to the top of the upper part of the clamping pad.

[0009] In one embodiment, the lower arm of the rotating arm has a through hole, the through hole is provided with an internal thread, and the through hole cooperates with the fastening bolt; the upper end of the fastening bolt is fixedly connected to the bottom of the lower part of the clamping pad.

[0010] In one embodiment, the bracket has a sliding groove in the length direction, the lower arm of the rotating arm is slidably installed on the sliding groove of the bracket, and the sliding groove is provided with a locking device.

[0011] Furthermore, the clamping pad is a rubber pad or a suction cup.

[0012] Furthermore, the bracket is provided with a connecting piece for fixing the bracket to the substrate glass sampling vehicle.

[0013] The utility model also discloses a substrate glass sampling vehicle, which has an A surface and a B surface in the same plane, and the A surface and the B surface are spliced by a rotating shaft; the aforementioned substrate glass sampling vehicle glass clamping device is assembled on the frame of the A surface and the B surface.

[0014] Furthermore, the glass clamping device of the substrate glass sampling vehicle is symmetrically arranged on the frame.

[0015] Specifically, the substrate glass sampling vehicle is equipped with 4 to 8 of the substrate glass sampling vehicle glass clamping devices.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] By adding a glass clamping device to the glass substrate sampling cart, the glass substrate is secured during inspection, preventing it from sliding and striking the edges of the cart due to the cart's tilting during inspection. This also eliminates the need for manual movement to secure the glass substrate. Furthermore, by employing latch connections or 90° hinges, the opening, closing, connection, and securing of objects are achieved through connection, rotation, and support. This reduces the number of manual steps required during inspection of glass substrates on the cart, facilitates manual securing of the glass substrate, and reduces operation time.
