Description

Technical Field

[0001] This utility model relates to the field of glass size detection technology, and in particular to a high-precision detection instrument for small-sized glass. Background Technology

[0002] In modern industrial production, small-sized glass is widely used in many fields such as electronics, optics, and medicine, such as smartphone displays, optical lenses, and observation windows of medical devices. These applications place extremely stringent requirements on the dimensional accuracy, surface quality, and internal defects of small-sized glass. Chinese utility model patent, authorized publication number "CN222799929U", discloses an optical quartz glass inspection device applicable to different sizes, including a worktable. The upper surface of the worktable has two sliding openings, each containing a slider. A first infrared rangefinder and a second infrared rangefinder are fixedly connected to the top of the sliders, respectively. A spring is fixedly connected to one side of each slider and is fixed to the sliding opening. A first limiting block and a second limiting block are fixedly connected to the upper surface of the worktable. A lifting assembly is provided at the top of the worktable, including two clearance grooves. These grooves are located at the top of the worktable, and a top plate is provided within each groove. Two connecting rods are fixedly connected to the bottom of the top plate.

[0003] The above technical solution not only enables the device to accurately and quickly measure the length and width of larger glass, but also allows workers to easily pick up the glass after the measurement is completed by lifting the component. However, the above technical solution still has certain drawbacks. When measuring the glass, workers still need to manually adjust the position of the infrared rangefinder. The length and width of the glass need to be measured separately during the glass measurement process, which is cumbersome and reduces the efficiency of the measurement. Therefore, this utility model proposes a new solution. Utility Model Content

This instrument can solve the problem that when testing glass, the operator still needs to manually adjust the position of the infrared rangefinder, and the length and width of the glass need to be measured separately during the testing process, which is cumbersome and reduces the testing efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a small-sized high-precision glass testing instrument, including a worktable;

[0006] A dimension detection component is set on a workbench. The dimension detection component includes a connecting frame, which is fixedly connected to the lower end of the workbench.

The movable frame is slidably connected to the first sliding groove.

[0008] An "L"-shaped glass measuring ruler is fixedly connected to the upper end of the workbench. Two sets of scales are opened on the inner surface of the glass measuring ruler. An infrared rangefinder receiver plate is fixedly connected to the outer side of the glass measuring ruler. An infrared rangefinder transmitter unit is fixedly connected to the upper end of the glass limit frame.

[0009] Preferably, the rack, the first slide groove, the movable frame, the glass limiting frame, the infrared rangefinder transmitting unit, and the infrared rangefinder receiving plate are each arranged in two sets symmetrically on the worktable.

[0010] Preferably, a second hydraulic rod is fixedly connected to the lower end of the workbench, and the output end of the second hydraulic rod slides through the workbench and is fixedly connected to a glass support plate;

[0018] 1. This high-precision testing instrument for small-sized glass uses a gear and rack transmission mechanism driven by a first hydraulic rod to move the symmetrically arranged movable frames and glass limiting frames on both sides synchronously. It can complete the simultaneous measurement of the length and width of small-sized glass in one go. Compared with the traditional technology that requires manual adjustment of the infrared rangefinder in each direction, this device avoids the cumbersome process of step-by-step testing, improves testing efficiency, and uses non-contact measurement between the transmitting unit and the infrared rangefinder receiving board to avoid the risk of scratching the glass surface caused by contact measurement. At the same time, the distance is accurately calculated by the beam transmission time, and the data is directly synchronized to the display screen, reducing the error of manual reading and improving the testing accuracy.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0029] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0030] Please see Figure 1-5 This utility model provides a technical solution: a high-precision glass testing instrument for small sizes, including a worktable 1 and a size detection component. The size detection component is mounted on the worktable 1 and includes a connecting frame 3, which is fixedly connected to the lower end of the worktable 1. A first hydraulic rod 11 is fixedly connected inside the connecting frame 3, and a gear frame 12 is fixedly connected to the output end of the first hydraulic rod 11. A gear 13 is rotatably connected to the inner side of the gear frame 12. A rack 14 is slidably connected to the upper right side of the connecting frame 3. 4 meshes with gear 13. The upper end of rack 14 is bolted with movable frame 7. The upper end of movable frame 7 is fixedly connected with glass limiting frame 8. The surface of worktable 1 has a first sliding groove 6. Movable frame 7 is slidably connected to the first sliding groove 6. The upper end of worktable 1 is fixedly connected with an "L"-shaped glass measuring ruler 5. The inner surface of glass measuring ruler 5 has two sets of scales. The outer side of glass measuring ruler 5 is fixedly connected with an infrared rangefinder receiver plate 10. The upper end of glass limiting frame 8 is fixedly connected with an infrared rangefinder transmitter unit 9.

[0031] The rack 14, the first slide 6, the movable frame 7, the glass limiting frame 8, the infrared rangefinder transmitting unit 9, and the infrared rangefinder receiving plate 10 are all arranged in two sets symmetrically on the workbench 1.

[0032] A second hydraulic rod 18 is fixedly connected to the lower end of the worktable 1. The output end of the second hydraulic rod 18 slides through the worktable 1 and is fixedly connected to a glass support plate 4. Two guide rods 19 are fixedly connected to the lower end of the glass support plate 4, and both guide rods 19 are slidably connected to the worktable 1.

[0033] The surface of the connecting frame 3 is provided with a second sliding groove 16. The gear frame 12 is slidably connected to the second sliding groove 16. The guides of the two first sliding grooves 6 and the second sliding groove 16 are consistent with the moving direction of the output end of the first hydraulic rod 11.

[0034] The left and right sides of the connecting frame 3 are fixedly connected with rack limit plates 15, and the two racks 14 are slidably connected to the corresponding rack limit plates 15 respectively.

[0035] The surface of the rack 14 has multiple mounting holes 17, and the surface of the movable frame 7 also has two mounting holes 17.

[0036] Four support plates 2 are fixedly connected to the lower end of the workbench 1.

[0037] When using the device, the second hydraulic rod 18 is activated, and its output end pushes the glass support plate 4 to rise from below the worktable 1. The guide rod 19 keeps the vertical movement, and the glass to be tested is placed on the glass support plate 4. The second hydraulic rod 18 retracts, driving the glass support plate 4 down to the surface of the worktable 1, so that the glass is stably positioned in the detection area inside the glass detection ruler 5. The glass detection ruler 5 is "L" shaped, providing reference edges in the length and width directions. One edge of the glass is in contact with the right angle edge of the detection ruler to achieve initial positioning.

[0038] The first hydraulic rod 11 is activated, and its output end pushes the gear frame 12 to move horizontally along the second slide groove 16 (the guide is consistent with the output direction of the first hydraulic rod 11); the gear frame 12 drives the inner gear 13 to move, and the gear 13 meshes with the rack 14, converting the linear motion of the hydraulic rod into the horizontal sliding of the rack 14 (the racks 14 on both sides move symmetrically).

[0039] The rack 14 is connected to the movable frame 7 by bolts, which drives the movable frame 7 to move along the first slide 6 toward the glass until the glass limiting frame 8 contacts one edge of the glass. The glass limiting frame 8 on the side in contact with the glass stops moving. Since the glass is usually rectangular, the glass limiting frame 8 will first contact the longer side of the glass. The other glass limiting frame 8 does not contact the side of the glass. One rack 14 stops moving, and the other rack 14 continues to move under the drive of the gear 13 until both glass limiting frames 8 contact both sides of the glass.

[0040] The glass limiting brackets 8 on both sides move symmetrically, transmitting signals from the infrared rangefinder transmitting unit 9 to the infrared rangefinder receiving board 10 on the corresponding side to measure the length and width of the glass in real time. Each set of infrared rangefinder transmitting unit 9 and infrared rangefinder receiving board 10 corresponds to the length and width directions of the glass, respectively. The distance is calculated by measuring the beam transmission time, and the data is directly displayed on the external display screen. Simultaneous detection on both sides avoids the tedious steps of traditional single-direction manual adjustment and improves detection efficiency.

[0041] During the glass size inspection process, staff can observe the scale corresponding to the glass inspection ruler 5 for auxiliary measurement, further improving the inspection accuracy; the rack limit plate 15 restricts the movement trajectory of the rack 14 to prevent lateral displacement; the meshing of the gear 13 and the rack 14 ensures that the movable frames 7 on both sides move synchronously, avoiding inspection deviation; the mounting hole 17 is used to adjust the connection position between the movable frame 7 and the rack 14 to adapt to the inspection needs of glass of different sizes (such as changing the bolt fixing hole position to adjust the initial spacing).

[0042] Guide rod 19 ensures the vertical accuracy of glass support plate 4 during lifting and lowering, and avoids glass tilting affecting the test results; support plate 2 improves the overall stability of worktable 1 and reduces vibration interference.

[0043] Furthermore, this device drives a gear and rack transmission mechanism via the first hydraulic rod 11, which in turn drives the symmetrically arranged movable frame 7 and glass limiting frame 8 to move synchronously, enabling simultaneous measurement of the length and width of small-sized glass in one operation. Compared to the traditional technology that requires manual adjustment of the infrared rangefinder in each direction, this avoids the cumbersome process of step-by-step detection, improving detection efficiency. The transmitting unit 9 and the infrared rangefinder receiving board 10 adopt non-contact measurement, avoiding the risk of scratching the glass surface caused by contact measurement. At the same time, the distance is accurately calculated through the beam transmission time, and the data is directly synchronized to the display screen, reducing manual reading errors and improving detection accuracy.
