Description

Technical Field

[0001] This utility model relates to the field of glass substrate technology, and in particular to a glass substrate sampling vehicle. Background Technology

[0002] In the production process of TFT-LCD (Liquid Crystal Display) glass substrates, in order to ensure that the production quality of the glass substrates meets the usage requirements, it is necessary to sample and inspect the glass substrates on the production line. In the existing technology, a relatively simple sampling cart is used to transport the glass substrates off the production line for testing. Since the glass substrates are relatively soft and fragile items with a length and width of about two meters and a thickness of less than one millimeter, the sampling cart can easily shake during transportation due to road conditions or operator error, causing the glass substrates to break. This not only causes economic losses but also poses safety hazards. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model proposes a sampling vehicle that can reliably transport glass substrates.

[0004] The glass substrate sampling cart includes: a base, a support frame, rollers, and a vacuum suction cup mechanism. The base is equipped with a traveling mechanism. The support frame includes several interconnected support rods forming a rectangular frame structure. The upper surfaces of the support rods form a flush support surface. The support rods at both ends of the support frame are rotatably connected to the base via horizontal pivots. Multiple rollers are spaced apart and connected to the upper surfaces of the support rods at the lower end of the support frame. The roller fixing shafts are perpendicular to the upper surfaces of the support rods. The vacuum suction cup mechanism is connected to the support frame. The suction surface of the vacuum suction cup is located inside the support frame and is flush with the upper surfaces of the support rods.

[0005] Preferably, mounting brackets are connected to the support rods at the four corners of the support frame, and the mounting brackets are provided with threaded holes that are compatible with the mounting threaded posts of the vacuum suction cup.

[0006] Preferably, the mounting bracket away from the roller has multiple threaded holes in the direction extending toward the roller, and the threaded holes are adapted to the mounting threaded posts of the vacuum chuck.

[0007] Preferably, the glass substrate sampling cart also includes a proximity sensor, a controller, and a solenoid valve. The two proximity sensors are respectively connected to the two ends of the upper surface of the lower support rod, the solenoid valve is connected to the air pipe of the vacuum suction cup mechanism, and the controller is electrically connected to the proximity sensor and the solenoid valve.

[0008] Preferably, rollers are connected to the support rods at both ends of the support frame at intervals.

[0009] Preferably, the roller is made of ultra-high molecular weight polyethylene.

[0010] Preferably, it also includes a plug rod, a first plate, and a second plate. The first plate with a first insertion hole is connected to the support rods at the left and right ends of the support frame, and the second plate with a second insertion hole is connected to the base. When the support frame is rotated to a preset tilt angle, the axes of the first insertion hole and the second insertion hole coincide, and the plug rod can be adapted to be inserted into the first insertion hole and the second insertion hole.

[0011] Preferably, it also includes protective support balls, with multiple protective support balls spaced apart and connected to the upper surface of the support rod, and their tops forming a flush support surface. The protective support balls are made of ultra-high molecular weight polyethylene.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] By installing vacuum suction cups on the support frame, it can be ensured that when the sampling vehicle moves and flips the glass substrate, the glass substrate will be fixed by the vacuum suction cups and will not shake or break, thus increasing the reliability and safety of the sampling vehicle.

[0014] The mounting bracket is equipped with multiple mounting threaded holes that are compatible with the mounting threaded posts of the vacuum suction cup, allowing the sampling vehicle to adsorb and fix glass substrates of different heights.

[0015] The protective support ball can protect the supported surface of the glass substrate from wear. Attached Figure Description

[0020] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] Reference Figures 1 to 4The glass substrate sampling cart includes: a base 1, a support frame 2, rollers 3, and a vacuum suction cup mechanism 4. The base 1 is equipped with a walking mechanism 11 (in practical applications, casters can be installed at the four corners of the base 1) to facilitate the movement of the sampling cart. The movable support frame 2 includes several interconnected support rods 21 forming a rectangular frame structure. The upper surfaces 211 of the support rods form a flush support surface for placing the glass substrate. The support rods 21 at both ends of the support frame 2 are rotatably connected to the base 1 via horizontal pivots 22, allowing for multi-angle adjustment of the support frame 2. This allows for slight tilting of the support frame 2 to prevent the glass substrate from falling, and also allows for inspection of the glass substrate on the sampling cart. As needed, the position of the support frame 2 is adjusted. Multiple rollers 3 are spaced apart and connected to the upper surface 211 of the support rod at the lower end of the support frame 2. The roller fixing shaft 31 is perpendicular to the upper surface 211 of the support rod. The rollers 3 can support and prevent the glass substrate from sliding off the support frame 2. At the same time, the glass substrate can be easily adjusted in position by rolling on the rollers 3. The vacuum suction cup mechanism 4 is connected to the support frame 2. The suction surface 411 of the vacuum suction cup 41 is located inside the support frame 2 and is flush with the upper surface 211 of the support rod. The vacuum suction cup 41 can provide a reliable suction force for the glass substrate, which can effectively prevent the glass substrate from falling and breaking due to shaking of the sampling vehicle, thereby improving the working reliability and safety of the sampling vehicle.

[0022] Reference Figure 1 , Figure 3 , Figure 4 Mounting brackets 23 are connected to the support rods 21 at the four corners of the support frame 2. The mounting brackets 23 have threaded holes 231 that are compatible with the mounting threaded posts 412 of the vacuum suction cups. Since the glass substrate is a relatively soft material, it may bend and deform in the middle when placed on the support frame 2. The vacuum suction cups 41 at the four corners of the support frame 2 can flatten the glass substrate and ensure the quality of the glass substrate. At the same time, this fixing method can reliably fix the glass substrate on the support frame 2 and ensure the safety during transportation and the flipping process of the support frame 2.

[0023] Reference Figure 1 , Figure 3 , Figure 4 The mounting bracket 23, which is away from the roller 3, has multiple threaded holes 231 in the direction extending toward the roller 3. The threaded holes 231 are adapted to the mounting threaded post 412 of the vacuum suction cup. Therefore, the mounting position of the vacuum suction cup 41 can be used to adapt to the adsorption and fixation of glass substrates of different heights.

[0024] Reference Figure 1 , Figure 3 , Figure 4The sampling vehicle also includes proximity sensors 5, a controller, and a solenoid valve. Two proximity sensors 5 are respectively connected to the two ends of the upper surface 211 of the lower support rod. The solenoid valve is connected to the air pipe of the vacuum suction cup mechanism 5. The controller is electrically connected to the proximity sensors and the solenoid valve. When the glass substrate is placed in the support frame 2, the proximity sensors 5 connected to the two ends of the upper surface 211 of the lower support rod will generate a sense and send a signal to the controller. The controller can then control the vacuum source to evacuate the vacuum suction cup 41 by controlling the solenoid valve, so as to form a strong negative pressure suction force and improve the automation level of the sampling vehicle.

[0025] Reference Figure 1 , Figure 3 The support rods 21 at both ends of the support frame 2 are connected to rollers 3 that are spaced apart. The glass substrate can lean against the roller 3 at one end, increasing the flexibility of the sampling vehicle.

[0026] To prevent damage to the glass substrate, roller 3 is made of ultra-high molecular weight polyethylene.

[0027] Reference Figures 1 to 4 The sampling vehicle also includes a rod 6, a first plate 7, and a second plate 8. The first plate 7, with a first insertion hole 71, is connected to the support rods 21 at both ends of the support frame 2. The second plate 8, with a second insertion hole 81, is connected to the base 1. When the support frame 2 rotates to a preset tilt angle, the axes of the first insertion hole 71 and the second insertion hole 81 coincide, and the rod 6 can be inserted into the first insertion hole 71 and the second insertion hole 81. Therefore, during movement and testing, the support frame 2 can be limited and fixed in a certain tilt position to prevent it from shaking and further protect the glass substrate.

[0028] Reference Figure 1 , Figure 3 The sampling vehicle also includes protective support balls 9. Multiple protective support balls 9 are spaced apart and connected to the upper surface 211 of the support rod, and their tops form a flush support surface. The protective support balls are made of ultra-high molecular weight polyethylene, which protects the glass substrate from wear by the support surface.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
