Description

Technical Field

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

[0002] As a core material in high-end fields such as flat panel displays and solar cells, the quality of substrate glass plays a decisive role in the performance and quality of end products. In the substrate glass production process, to ensure that products meet stringent quality standards, high-frequency, high-precision sampling and testing of the substrate glass on the production line is essential.

[0003] With the continuous advancement of substrate glass production technology and the increasing size of glass, manual sampling of large-size substrate glass faces numerous challenges. Large-size glass is heavy, making it difficult for manual operators to directly rotate and adjust the angle, hindering the convenient selection of samples from different parts and affecting the comprehensiveness and accuracy of sampling. Manual handling and rotation also easily cause scratches and damage to the glass surface, increasing production costs and even preventing the acquisition of effective test data due to sample damage, thus reducing testing efficiency. Furthermore, while some existing sampling equipment can assist in sampling, most are complex in structure and cumbersome to operate, failing to meet the needs for rapid and flexible rotational sampling. Large-size substrate glass (such as G10.5 generation glass with dimensions of 3370mm × 2940mm) places extremely high demands on the precision, stability, and load-bearing capacity of sampling equipment. Existing automated equipment requires customization for specific sizes, resulting in high research and development and procurement costs, which many companies cannot replace in the short term. Utility Model Content

[0004] To address the existing problems, this utility model provides a substrate glass sampling rotary trolley, which aims to solve the problems of inconvenient manual operation and difficulty in rotating the sample during the inspection and sampling of large-size glass, so as to achieve convenient and efficient substrate glass sampling, and improve sampling accuracy and work efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A substrate glass sampling rotary trolley includes a trolley body, a flipping frame, and a sampling frame; bearing seats are provided at the front and rear ends of the top corner of the trolley body, the bearing seats are rotatably connected to the flipping frame, and the flipping frame is rotatably connected to the sampling frame through a slewing bearing; the planes on which the flipping frame and the sampling frame are located are parallel, and the rotation axis of the slewing bearing is perpendicular to the planes on which the flipping frame and the sampling frame are located; casters are provided at the bottom of the trolley body.

[0007] As a further improvement of this utility model, a limiting block is provided on the side of the vehicle body near the bearing seat.

[0008] As a further improvement of this utility model, a buffer block is provided on the side of the vehicle body near the bearing seat, and the line connecting the outer end of the buffer block and the bearing seat is located outside the line connecting the outer end of the limiting block and the bearing seat.

[0009] As a further improvement of this utility model, the flipping frame is provided with a positioning pin hole, and the sampling frame is provided with a positioning pin that cooperates with the positioning pin hole.

[0010] As a further improvement of this utility model, adjustable support legs are provided at the bottom of the vehicle body.

[0011] As a further improvement of this utility model, a counterweight is provided on the side of the vehicle body away from the bearing seat.

[0012] As a further improvement of this utility model, infrared alarms are provided at the front and rear ends of the vehicle body to provide obstacle warnings for the accessible area of ​​the tilting frame.

[0013] As a further improvement of this utility model, the infrared alarm includes an infrared sensor and an audible and visual alarm.

[0014] As a further improvement of this utility model, the sampling frame is provided with an inwardly recessed slot.

[0015] As a further improvement of this utility model, an angle locking device is added between the vehicle body and the tilting frame.

[0016] This utility model has the following beneficial effects: The vehicle body has bearing seats at the front and rear of the top corner, which are rotatably connected to the flipping frame. The flipping frame is connected to the sampling frame through a slewing bearing. This design allows the sampling frame to rotate flexibly, making it convenient to sample the substrate glass from different angles.

[0017] A limiting block is installed on the side of the vehicle body near the bearing seat to limit the rotation range of the tilting frame, preventing excessive rotation from damaging the equipment or affecting sampling operations. An added buffer block acts as a cushion when the tilting frame approaches the limiting position, reducing impact and extending the equipment's lifespan. The positioning pin holes on the tilting frame cooperate with the positioning pins of the sampling frame to precisely position the sampling frame, ensuring accurate positioning during sampling and improving sampling quality.

[0018] The cart is equipped with casters at the bottom, allowing it to move freely within the workshop, saving manpower and improving sampling efficiency. Adjustable support legs at the bottom of the cart allow for height adjustment when the cart is stationary, ensuring greater stability.

[0019] A counterweight on the side of the trolley away from the bearing seat balances the trolley's center of gravity, preventing it from tipping over due to excessive weight on one side and enhancing stability. Infrared alarms at the front and rear of the trolley provide obstacle warnings within the reach of the tilting frame, promptly alerting operators to avoid obstacles and ensuring operational safety. Inward-facing slots on the sampling frame frame facilitate securing the substrate glass, preventing it from slipping during sampling. An angle locking device between the trolley and the tilting frame locks in place after the sampling angle is determined, ensuring a stable and reliable sampling process. Attached Figure Description

[0024] Example 1 like Figure 1 As shown, a substrate glass sampling rotary trolley includes a trolley body 1, a flipping frame 2, and a sampling frame 4.

[0025] Bearing seats 5 are provided at both ends of the top corner of the vehicle body 1, and the bearing seats 5 are rotatably connected to the tilting frame 2. Specifically, the protruding shaft of the tilting frame 2 is inserted into the bearing seat 5. The bearing seats 5 enable the tilting frame 2 to rotate stably relative to the vehicle body 1, with a maximum tilting angle of 80° (e.g., ...). Figure 1 As shown), the minimum is 0° (e.g. Figure 2 (As shown).

[0026] like Figure 3 As shown, the tilting frame 2 is rotatably connected to the sampling frame 4 via a slewing bearing 3. The sampling frame 4 is connected to the outer ring of the slewing bearing 3 by bolts and can rotate with the outer ring of the slewing bearing 3; the tilting frame 2 is connected to the inner ring of the slewing bearing 3 by bolts, thereby driving the sampling frame 4 to rotate, with a maximum rotation angle of 360° and a minimum of 0°. Preferably, the planes on which the tilting frame 2 and the sampling frame 4 are located are parallel, and the rotation axis of the slewing bearing 3 is perpendicular to the plane on which the tilting frame 2 and the sampling frame 4 are located. Specifically, the main frame of the vehicle body 1 is constructed from aluminum profiles, which is lightweight, high-strength, and corrosion-resistant. The bearing housing 5 is bolted to the aluminum profile frame of the vehicle body 1 and is used to connect with the tilting frame 2.

[0027] like Figure 1 As shown, a limiting block 6 is provided on the side of the vehicle body 1 near the bearing seat 5. The limiting block 6 can limit the rotation angle range of the rotating frame, prevent the rotating frame from rotating excessively and damaging the trolley structure or affecting the sampling operation, ensure that the rotating frame rotates within a safe and reasonable angle, and improve the safety and stability of the trolley.

[0028] like Figure 1 As shown, a buffer block 7 is provided on the side of the vehicle body 1 near the bearing seat 5. The line connecting the outer end of the buffer block 7 to the bearing seat 5 is located outside the line connecting the outer end of the limiting block 6 to the bearing seat 5. The buffer block 7 is located on the edge of the aluminum profile frame and can play a buffering role during the flipping process of the flipping frame 2 to avoid damage to the glass from collision. Both the limiting block 6 and the buffer block 7 are fixed to the vehicle body 1 with bolts.

[0029] The flipping frame 2 is provided with a positioning pin hole, and the sampling frame 4 is provided with a positioning pin 10 that cooperates with the positioning pin hole. The sampling frame 4 and the flipping frame 2 are fixed by the positioning pin 10 when not rotating, and can be rotated by removing the positioning pin 10.

[0030] like Figure 1-3 As shown, casters 8 are provided at the bottom of the vehicle body 1. The casters 8 are bolted to the four corners of the bottom of the aluminum profile frame, which facilitates the movement of the vehicle on the ground. Some of the casters 8 are equipped with brake devices, which can fix the vehicle after reaching the designated position.

[0031] The bottom of the vehicle body 1 is equipped with adjustable support legs. The adjustable support legs can keep the vehicle body 1 level and stable when placed, prevent the casters 8 from slipping when flipping or rotating, and ensure normal use of the vehicle even on uneven ground, thus enhancing the adaptability and stability of the vehicle.

[0032] A counterweight 9 is provided on the side of the vehicle body 1 away from the bearing seat 5. The counterweight 9 is fixed to the bottom of the aluminum profile frame with bolts to increase the stability of the trolley and prevent the trolley from tipping over when carrying glass.

[0033] The sampling rack 4 has inward-facing slots on its side.

[0034] When using the sampling trolley, first push the sampling trolley to the sampling substrate glass position using casters 8, and fix the sampling frame 4 with positioning pins 10 to prevent the sampling frame 4 from rotating during the placement of the substrate glass; then use a robotic arm to place the substrate glass on the sampling frame 4 of the sampling trolley with the help of a vacuum suction cup; then push the sampling trolley to the detection position for detection; when it is necessary to sample the substrate glass at different angles, manually flip the sampling trolley flat, remove the positioning pins 10, and manually rotate the sampling frame 4. The slewing bearing 3 enables the sampling frame 4 to rotate flexibly to cope with various angles required during inspection and sampling.

[0035] Example 2 The difference between this embodiment and Embodiment 1 is that: 1) The front and rear ends of the vehicle body 1 are equipped with infrared alarms to provide obstacle warnings for the accessible area of ​​the tilting frame 2.

[0036] 2) The infrared alarm includes an infrared sensor and an audible and visual alarm.

[0037] The infrared alarm can monitor the area accessible to the tilting frame 2 in real time for the presence of obstacles. When an obstacle is detected, it will issue an early warning in time to prevent the tilting frame 2 from colliding with the obstacle during rotation, thus ensuring the safety of the trolley operation and the safety of surrounding personnel and equipment. The infrared sensor can accurately detect obstacles, while the audible and visual alarm can issue an alarm simultaneously through both sound and light, allowing operators to respond more promptly.

[0038] Example 3 The difference between this embodiment and Embodiment 1 is that: An angle locking device is added between the vehicle body 1 and the tilting frame 2.

[0039] The angle locking device can be any of the following types: snap-on, gear-type, or damping-type. The snap-on type achieves positioning by the engagement of a metal spring and a slot. The gear-type uses gear transmission to adjust the angle and fixes the angle through friction between gears or a locking mechanism. The damping-type uses a hydraulic or pneumatic damper to buffer the rotation speed of the object to achieve support at a specific angle. The angle locking device can lock the tilting frame 2 after it has rotated to the required angle, keeping the tilting frame 2 fixed and preventing the tilting frame 2 from rotating due to unexpected factors during the sampling process, which would affect the sampling operation and improve the stability and reliability of the sampling.

[0040] The above embodiments are merely one of the implementation methods for achieving the technical solution of this utility model. The scope of protection claimed by this utility model is not limited to this embodiment, but also includes any variations, substitutions, and other implementation methods that are easily conceived by those skilled in the art within the scope of the technology disclosed in this utility model.
