Description

Technical Field

[0001] This utility model relates to the field of glass substrate measurement technology, specifically to a device for measuring the offset and deflection angle of a glass substrate. Background Technology

[0002] When G8.5+ generation glass substrates are packaged on horizontal frames, they are prone to positional shifts due to transportation vibrations, stacking pressure, or changes in ambient temperature and humidity. This can lead to positioning failures during subsequent automated handling or processing, and even glass breakage. After the product is packaged, employees manually use a ruler to measure the edge offset and visually inspect whether it deviates from the base plate. However, manual visual inspection is inefficient and inaccurate. The ruler can easily scratch the glass surface when in direct contact with it, and it is difficult to cover the entire area of ​​large-sized glass. At the same time, the existing mechanism is not adapted to the support structure of horizontal frame packaging, resulting in insufficient installation stability and the inability to measure the glass offset angle.

[0017] Reference Figures 1 to 4 As shown, this utility model provides a device for measuring the offset and deflection angle of a glass substrate, comprising: a positioning frame 3, which is movably connected to the upper surface of a handle 1 by a main bolt 5, and two sets of positioning plates 2 are fixedly connected to the upper and lower ends of the handle 1. The positioning frame 3 has symmetrical through slots 6 at both ends, and positioning holes and buffer slots are respectively opened at the top of the through slots 6. A secondary bolt 7 is screwed into the positioning hole, and a buffer layer 9 is fixedly connected in the buffer slot. At the same time, a guide slot 11 is opened on the surface of the caliper 4 corresponding to the position of the secondary bolt 7. The caliper 4 is slidably connected in the through slot 6 through the guide slot 11. A locking slot is symmetrically opened on the side of the caliper slot. One end of the probe 12 is fixedly connected in the locking slot, and the other end of the probe 12 is fixedly connected to the probe 13. An angle ruler 10 is fixedly connected to the middle of the inner side of the positioning frame 3, and an indicator plate 8 is fixedly connected to the surface of the positioning plate 2 near the angle ruler 10.

[0018] In this embodiment, the inspector holds the handle 1 and clamps the positioning plate 2 tightly against the vertical beam at the corner of the horizontal frame on which the glass substrate is mounted. The inspector then pushes the calipers 4, which are slidably connected at both ends of the positioning frame 3. The calipers 4 can abut against the edge of the glass substrate through the probe 13 fixedly connected to the end of the probe 12. When the probe 13 of all probes 12 abuts against the edge of the glass substrate, the calipers 4 can assist in adjusting the angle of the positioning frame 3 through the limiting effect of the secondary bolt 7. This allows the angle ruler 10 fixedly connected inside the positioning frame 3 to rotate relative to the positioning plate 2 and the indicator plate 8. Therefore, the inspector can sequentially record the offset data of the calipers 4 at both ends of the positioning frame 3 and the deflection angle data of the angle ruler 10, thereby completing the measurement of the relevant offset data of the glass substrate.

[0019] As a preferred embodiment, the positioning frame 3 has an overall L-shaped structure, the two sets of through slots 6 opened at both ends of the positioning frame 3 are rectangular, and a through hole is opened at the corner of the middle of the positioning frame 3.

[0020] In this embodiment, as Figure 1 and Figure 3 The through slots 6 at both ends of the positioning frame 3 allow the caliper 4 to slide relative to the positioning frame 3, thus facilitating the measurement of the offset of the glass substrate by the caliper 4. The through holes allow the positioning frame 3 to rotate on the upper surface of the handle 1, thereby facilitating the measurement of the deflection angle of the glass substrate by the device.

[0021] As a preferred embodiment, two sets of positioning holes are symmetrically opened at the top of the through groove 6, and threaded structures are opened on the inner side of both sets of positioning holes. The first end of the auxiliary bolt 7 is threaded, and the auxiliary bolt 7 is screwed and fixed to the positioning hole through the threaded structure at the first end. At the same time, the tail end of the auxiliary bolt 7 abuts against the bottom of the through groove 6.

[0022] In this embodiment, as Figure 1 , Figure 2 and Figure 3 , the arrangement of the thread structure on the surface of the auxiliary bolt 7 enables the auxiliary bolt 7 to be fixedly connected to the surface of the positioning frame 3 and also limits the moving range of the caliper 4 in the through groove 6, avoiding the accidental detachment of the caliper 4 from the through groove 6 and improving the convenience of loading and unloading of the device.

[0023] As a preferred embodiment, the buffer groove opened at the top of the through groove 6 is located between two groups of positioning holes. The buffer groove has a rectangular structure, and the sizes of the buffer groove and the buffer layer 9 are adapted to each other. At the same time, the lower surface of the buffer layer 9 abuts against the upper surface of the caliper 4.

[0024] In this embodiment, as Figure 1 and Figure 2 , the buffer layer 9 is made of silica gel material, which can then assist in increasing the frictional resistance when the caliper 4 moves in the through groove 6, and then can reduce the probability of accidental movement of the caliper 4, ensuring the convenience and accuracy when the tester records data.

[0025] As a preferred embodiment, the caliper 4 has a rectangular structure, the sizes of the caliper 4 and the through groove 6 are adapted to each other, and the two groups of guiding grooves 11 opened on the surface of the caliper 4 are both in a long strip structure. At both ends of the upper surface of the caliper 4, two groups of scale lines are symmetrically opened, and at the same time, the caliper 4 and the guiding grooves 11 are combined together to form a structure like the Chinese character "mu".

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 , the opening of the guiding grooves 11 enables the caliper 4 to be stably slidably connected in the through groove 6, and can also cooperate with the auxiliary bolt 7 to assist in enhancing the stability when the caliper 4 moves. At the same time, the opening of the scale lines facilitates the data recording of the tester after the caliper 4 measures the offset of the glass substrate.

[0027] As a preferred embodiment, on one side of the caliper 4 close to the angle gauge 10, a plurality of engaging grooves are opened in parallel at equal intervals along the length direction. The plurality of engaging grooves are all in a rectangular structure, and the axial cross-section of the probe 12 is in a T-shaped structure. The mounting part of the probe 12 is fixedly connected to the engaging groove by a buckle, and at the same time, the probe head 13 fixedly connected to the probe 12 has a spherical structure.

[0028] In this embodiment, as Figure 2 , Figure 3 and Figure 4The locking groove allows for easy mounting and dismounting of the caliper 4 and the probe 12. The probe 12 can also be installed at different positions on the side of the caliper 4 as needed, thereby improving the coverage of the device when measuring the glass substrate. Meanwhile, the probe 13 is made of silicone, which helps to reduce the chance of scratching the surface of the glass substrate when measuring it, ensuring the yield of the glass substrate.

[0029] As a preferred embodiment, the handle 1 has an hourglass shape, and anti-slip stripes are evenly distributed on the surface of the handle 1. The two sets of positioning plates 2 that are fixedly connected to both ends of the handle 1 are rectangular. The end of the positioning plate 2 away from the handle 1 has a slot, which is a right-angled isosceles triangle. At the same time, a screw hole is provided on the upper surface of the handle 1, and the tail end of the main bolt 5 has a threaded structure. The tail end of the main bolt 5 passes through the through hole and is screwed into the screw hole.

[0030] In this embodiment, as Figure 1 , Figure 3 and Figure 4 The structure of the handle 1 can help enhance the comfort of the worker when holding it and reduce the chance of slipping. The slots opened on the positioning plate 2 can also help enhance the convenience of positioning the positioning plate 2, ensure the stability of the device during use, and improve the accuracy of offset and deflection angle measurement.
