Description

Technical Field

[0001] This utility model relates to the field of glass size detection technology, specifically a glass size detection device with positioning function. Background Technology

[0002] Glass is an amorphous inorganic non-metallic material, generally made from a variety of inorganic minerals such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, and soda ash as the main raw materials, with the addition of small amounts of auxiliary materials. Its main components are silicon dioxide and other oxides. The wide range of its applications places almost stringent requirements on dimensional accuracy, geometry, and functional reliability. Dimensional accuracy is not only a matter of aesthetics but also fundamental to ensuring safety, sealing properties, and efficient assembly, directly affecting the quality and performance of the final product. Against this backdrop, glass dimensional inspection equipment, as a key component of the quality control system, is playing an increasingly important role.

[0003] Currently, some automated inspection equipment has been developed and applied in the field of glass size inspection. For example, the utility model patent with authorization announcement number CN222560818U discloses a glass size information inspection and acquisition device, which realizes automated measurement of glass size by setting a rotating seat, a vacuum suction cup, and an adjustable thickness and distance measuring mechanism. Compared with manual measurement, it has significantly improved accuracy and efficiency. However, such devices usually adopt a central rotating layout, and its positioning method has limitations for fixing rectangular glass. It is difficult to adapt to different models of glass with large differences in length and width ratio at the same time. Moreover, the movement trajectory of its measurement module and the adjustment range of the support point are limited. When dealing with large-size or ultra-thin glass, it is easy to cause glass deformation or measurement errors due to unstable support or uneven clamping force. In addition, its measurement function modules are relatively independent, making it difficult to achieve efficient synchronous measurement of multiple dimensional parameters such as length, width, and thickness of glass, which restricts further improvement of inspection efficiency. Therefore, we propose a glass size inspection device with positioning function. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a glass size detection device with positioning function, comprising a base and a mounting base. The mounting base is fixedly installed within the base. Four sets of symmetrically distributed first, second, third, and fourth limiting blocks are provided above the base. The base contains a limiting adjustment mechanism for adjusting the spacing between the multiple sets of limiting blocks. The mounting base is provided with a support mechanism. A first laser ranging sensor and a second laser ranging sensor are embedded in the first limiting block, and the first and second laser ranging sensors are vertically distributed. A first reflector is embedded in the second limiting block, a second reflector is embedded in the third limiting block, and a spectral confocal sensor is fixedly installed on the fourth limiting block.

[0005] In some embodiments, the first reflector is correspondingly disposed with the first laser ranging sensor, and the second reflector is correspondingly disposed with the second laser ranging sensor. The limiting adjustment mechanism includes two sets of first push rods symmetrically distributed in the base, and the limiting adjustment mechanism also includes two sets of second push rods symmetrically distributed in the base. Both sets of first push rods and second push rods are slidably connected to the base. The first push rods and second push rods are vertically distributed. The first limiting block, the second limiting block, the third limiting block and the fourth limiting block are slidably connected to a corresponding set of first push rods and second push rods, respectively.

[0006] In some embodiments, the base is provided with two sets of vertically distributed bidirectional lead screws, the two ends of the two sets of bidirectional lead screws passing through the base and rotatably connected to the base through rolling bearings.

[0007] In some embodiments, the two sets of bidirectional lead screws are respectively configured to correspond to the first push rod and the second push rod, and the two ends of the two sets of bidirectional lead screws respectively pass through the corresponding two sets of first push rods or the corresponding two sets of second push rods and are respectively threaded to the first push rod or the second push rod.

[0008] In some embodiments, the support mechanism includes an adjusting plate rotatably mounted in a mounting base, three sets of guide rails are fixedly mounted in the mounting base, adjusting frames are slidably mounted in each of the three sets of guide rails, support rods are fixedly mounted on each of the three sets of adjusting frames, and a drive wheel is rotatably mounted in the mounting base.

[0009] In some embodiments, a toothed ring is fitted onto the adjusting disc, and the drive wheel is meshed with the toothed ring.

[0010] In some embodiments, the adjusting plate has three sets of annularly distributed adjusting grooves, the three sets of adjusting grooves are correspondingly arranged with three sets of adjusting frames, and adjusting rods are fixedly installed on each of the three sets of adjusting frames. The three sets of adjusting frames are slidably connected to the adjusting plate through the corresponding adjusting grooves.

[0011] This utility model has at least the following beneficial effects:

[0012] 1. The first and second push rods, symmetrically distributed by the limit adjustment mechanism, move synchronously in opposite directions, thereby driving the first, second, third, and fourth limit blocks fixed on them to move synchronously. This allows for rapid adaptation to rectangular glass of different lengths and widths, achieving precise center positioning. Simultaneously, the first and second laser rangefinders, vertically arranged on the first limit block, along with the first reflector on the second limit block and the second reflector on the third limit block, can simultaneously measure the length and width of the glass. The spectral confocal sensor installed on the fourth limit block can measure the thickness of the glass with high precision. This enables efficient, synchronous, and automated detection of multiple dimensions of the glass, including length, width, and thickness, significantly improving detection efficiency and measurement accuracy.

[0013] 2. The drive wheel in the support mechanism drives the gear ring and adjusting plate to rotate through meshing transmission. In turn, the three sets of annular adjusting grooves on the plate drive the three sets of adjusting rods and the connected adjusting frame to slide synchronously radially along the guide rail. This causes the three sets of support rods to retract or extend synchronously, forming an adaptively adjustable support plane. This support plane can coordinate with the positioning action of the four sets of limiting blocks to ensure that glass of different sizes always receives stable support in the central area during the clamping and positioning process of the limiting blocks. This effectively avoids glass bending, deformation or even damage caused by suspension or uneven force. It is especially suitable for the safe and stable placement and measurement of large or ultra-thin glass. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1:

[0021] Please see Figure 1-3 This utility model provides a technical solution: a glass size detection device with positioning function, including a base 1 and a mounting base 2. The mounting base 2 is fixedly installed in the base 1. Four sets of symmetrically distributed first limiting blocks 3, second limiting blocks 4, third limiting blocks 5, and fourth limiting blocks 6 are provided above the base 1. The base 1 is provided with a limiting adjustment mechanism 7 for adjusting the spacing between the multiple sets of limiting blocks. The mounting base 2 is provided with a support mechanism 8. A first laser ranging sensor 704 and a second laser ranging sensor 705 are embedded in the first limiting block 3. The first laser ranging sensor 704 and the second laser ranging sensor 705 are vertically distributed. A first reflector 706 is embedded in the second limiting block 4. A second reflector 707 is embedded in the third limiting block 5. The fourth limiting block... A spectral confocal sensor 708 is fixedly installed on the fourth limit block 6. Four sets of limiting blocks can clamp the center position of glass of different sizes. At the same time, the first laser rangefinder 704, which is vertically installed on the first limiting block 3, emits a laser to the first reflector 706 on the second limiting block 4. By receiving the reflected light signal, the length of the glass is accurately calculated. The second laser rangefinder 705 on the third limit block 5 measures the width of the glass through the second reflector 707 on the third limiting block 5. Meanwhile, the spectral confocal sensor 708 on the fourth limit block 6 emits a light source to the upper surface of the glass corner. By analyzing the wavelength change of the confocal spot, the thickness of the glass is measured with high precision. Thus, the length, width and thickness of the glass are measured synchronously, quickly and non-contactly.

[0022] The first reflector 706 is correspondingly arranged with the first laser rangefinder 704, and the second reflector 707 is correspondingly arranged with the second laser rangefinder 705. The limiting adjustment mechanism 7 includes two sets of first push rods 701 symmetrically distributed in the base 1, and two sets of second push rods 702 symmetrically distributed in the base 1. Both sets of first push rods 701 and second push rods 702 are slidably connected to the base 1. The first push rods 701 and second push rods 702 are vertically distributed. The first limiting block 3, the second limiting block 4, and the first limiting block 705 are also included. The third limiting block 5 and the fourth limiting block 6 are slidably connected to a set of corresponding first push rods 701 and second push rods 702 respectively. The limiting adjustment mechanism 7 drives two sets of vertically arranged bidirectional lead screws 703 to rotate synchronously through a motor, which drives the first push rod 701 and the second push rod 702, which are threaded to each other, to slide in opposite directions within the base 1, thereby synchronously adjusting the distance between the first limiting block 3, the second limiting block 4, the third limiting block 5 and the fourth limiting block 6 fixed thereon, so that the four sets of limiting blocks can be centered and clamped to position the glass from the four corners.

[0023] The base 1 is equipped with two sets of vertically distributed bidirectional lead screws 703. The two ends of the two sets of bidirectional lead screws 703 pass through the base 1 and are rotatably connected to the base 1 through rolling bearings. The two sets of bidirectional lead screws 703 are respectively set with the first push rod 701 and the second push rod 702. The two ends of the two sets of bidirectional lead screws 703 pass through the corresponding two sets of first push rods 701 or the corresponding two sets of second push rods 702 and are threadedly connected to the first push rod 701 or the second push rod 702 respectively. During the rotation of the bidirectional lead screws 703, under the limiting action of the base 1, the two sets of first push rods 701 and the two sets of second push rods 702 slide inward or outward simultaneously, thereby realizing the adjustment of the distance between the four sets of first limiting blocks 3, second limiting blocks 4, third limiting blocks 5 and fourth limiting blocks 6.

[0024] Example 2:

[0025] Please see Figure 4 The support mechanism 8 includes an adjusting plate 801 rotatably mounted in the mounting base 2. Three sets of guide rails 808 are fixedly mounted in the mounting base 2. Adjusting frames 805 are slidably mounted in each of the three sets of guide rails 808. Support rods 806 are fixedly mounted on each of the three sets of adjusting frames 805. A drive wheel 803 is rotatably mounted in the mounting base 2. The three sets of ring-shaped support rods 806 together form a support surface. This support surface can adaptively adjust its support range according to the positioning position of the limit block, ensuring that the central area of ​​the glass can obtain uniform and stable support under any size. This effectively prevents the glass from bending or vibrating due to its own weight or clamping force, and ensures the stability of the measurement process and the accuracy of the results.

[0026] A gear ring 802 is fitted onto the adjusting disc 801, and the drive wheel 803 meshes with the gear ring 802. The adjusting disc 801 has three sets of annularly distributed adjusting grooves 804, which correspond to three sets of adjusting frames 805. Adjusting rods 807 are fixedly installed on each of the three sets of adjusting frames 805. The three sets of adjusting frames 805 are slidably connected to the adjusting disc 801 through their respective adjusting grooves 804. During the glass positioning and measurement process, the support mechanism 8 operates synchronously; the drive wheel 803 is driven by the drive motor. 03 rotates, the drive wheel 803 meshes with the gear ring 802 sleeved on the adjusting plate 801, driving the adjusting plate 801 to rotate within the mounting base 2; the three sets of annular distributed adjusting grooves 804 opened on the adjusting plate 801 rotate accordingly, and drive the adjusting rod 807 that slides with it to move radially, thereby driving the three sets of adjusting frames 805 to slide synchronously and smoothly along the guide rail 808 fixed in the mounting base 2, and finally making the three sets of support rods 806 fixed at the top of the adjusting frame 805 form a radially expandable support plane.
