Description

Technical Field

[0001] The invention relates to the technical field of glass detection, in particular to a high-precision glass thickness detection device. Background Art

[0002] As an important material widely used in many fields such as construction, automobiles, electronics, and optical instruments, the stability of glass quality and performance is of vital importance. With the rapid development of various industries, the quality requirements for glass are becoming increasingly stringent. The rise of emerging application fields such as electronic device screen glass and solar photovoltaic glass has brought new testing challenges to the surface hardness, scratch resistance, electrical properties, and long-term stability of glass.

[0003] During the glass production process, accurate thickness testing ensures that products meet quality standards. For example, for architectural glass, if the thickness does not meet the requirements, it may affect its strength and thermal and sound insulation performance. Automotive glass that does not meet thickness specifications may cause installation problems and greatly compromise safety performance, such as not providing adequate protection in the event of a collision.

[0004] At present, in the production process of flat glass, the thickness of the glass needs to be tested by thickness testing equipment. The traditional glass thickness testing method mainly relies on simple caliper measurement or some conventional measuring tools. These methods are not only cumbersome to operate, but also difficult to ensure accuracy and are easily interfered by human factors. In addition, during the testing process, the fixing method of the glass is often rough, which cannot ensure that the glass is in a stable state during testing, further affecting the accuracy of the test results.

[0005] Specifically, the glass needs to be clamped with a clamp and then placed on a thickness detection device for detection. However, when the work is done manually, only one piece of glass can be clamped at a time, and the clamping operation is cumbersome, which seriously affects the work efficiency during detection. Summary of the invention

[0006] The purpose of the present invention is to provide a high-precision glass thickness detection device to solve the problem in the market raised by the above background technology that only one piece of glass can be clamped at a time and the clamping operation is cumbersome, which seriously affects the work efficiency during detection.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions: A high-precision glass thickness detection device comprises a thickness detector for detecting the thickness of the glass to be tested, and further comprises: A base, with a column disposed on the upper portion thereof, extending upward from the upper end surface of the base; The workbench is arranged at the upper end of the base, and includes a clamping assembly on the workbench for clamping the glass to be tested; the clamping assembly at least includes: A fixed block is horizontally rotatably arranged on the workbench, and a plurality of placement slots with openings facing outwards are arranged at intervals on the outer side of the fixed block for placing the glass to be tested; A fixing ring is arranged on the working table and covered on the periphery of the fixing block, and the inner wall of the fixing ring is spaced radially from the placement groove; a plurality of abutment plates whose number matches the number of the placement grooves are arranged at intervals on the fixing ring, and the abutment plates can reciprocate toward the placement grooves to clamp the glass to be tested.

[0008] Preferably, a moving rod is provided on one side of the abutment plate, and the moving rod penetrates the side wall of the fixing ring and is slidably connected thereto; The clamping assembly further comprises: A rotating ring is rotatably connected to the workbench and is covered on the periphery of the fixed ring, wherein the ring diameter of the rotating ring is larger than the ring diameter of the fixed ring; The arc-shaped slider is arranged on the inner ring wall of the rotating ring and is located between the rotating ring and the fixed ring. The arc-shaped slider is used to squeeze the moving rod to move into the placement groove during the rotation of the rotating ring.

[0009] Preferably, a spring is sleeved on the outer side of the moving rod, and two sides of the spring are respectively connected to the moving rod and the side wall of the fixing ring.

[0010] Preferably, a curved surface is provided on the side of the curved slider close to the fixed ring, and the curved surface gradually bends and extends from the connection of the rotating ring to the side close to the fixed ring, and the extension direction of the curved surfaces of each curved slider is consistent.

[0011] Preferably, a plurality of anti-skid grooves are arranged at intervals on the outer side of the rotating ring, the notch of each anti-skid groove has a chamfer, and the notch of the anti-skid groove contacts the workbench.

[0012] Preferably, the size of the slot of the placement slot is equal to the length of the abutment plate.

[0013] Preferably, an annular slide groove is provided at the bottom of the workbench, and a damping sliding connection is arranged between the annular slide groove and the rotating ring.

[0014] Preferably, the bottom of the placement groove is recessed inward to form an arc-shaped groove.

[0015] Preferably, the height of the rotating ring is greater than the horizontal height of the moving rod.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention fixes the glass to be tested on the working table by setting components such as the base, the column and the thickness detector, and places the working table under the thickness detector, so that the thickness detector detects the thickness of the glass; 2. The present invention places the glass to be inspected in the plurality of placement grooves provided on the moving plate respectively by setting components such as a moving plate, an annular slide groove, a placement groove, a fixed ring, a moving rod and a stop plate. The rotating ring is rotated, and the arc-shaped slider fixedly connected to the inner side wall of the rotating ring rotates accordingly. Due to the curvature setting of the arc-shaped slider, when the arc-shaped slider rotates, it pushes the moving rod to move toward the inner side of the fixed ring, thereby pushing the stop plate to clamp the glass in the placement groove, thereby realizing the glass clamping function; 3. By setting an arc-shaped slider, and the arc surface of the arc-shaped slider gradually bends and extends from the connection of the rotating ring to the side close to the fixed ring, the extension direction of the arc surface of each arc-shaped slider is consistent.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-5 A high-precision glass thickness detection device includes a thickness detector 4 for detecting the thickness of the glass to be tested, and also includes: A base 1 is provided with a column 2 on the upper portion thereof, extending upward from the upper end surface of the base 1; The workbench 5 is arranged at the upper end of the base 1, and the workbench 5 includes a clamping assembly for clamping the glass to be tested; the clamping assembly at least includes: The fixed block 6 is horizontally rotatably disposed on the workbench 5, and a plurality of placement grooves 10 with openings facing outward are arranged at intervals on the outer side of the fixed block 6 for placing the glass to be tested; The fixing ring 7 is arranged on the working table 5 and is covered on the periphery of the fixing block 6. The inner wall of the fixing ring 7 is spaced apart from the placement groove 10 in the radial direction. A plurality of abutment plates 17 whose number matches the number of the placement grooves 10 are arranged at intervals on the fixing ring 7. The abutment plates 17 can move back and forth toward the placement grooves 10 to clamp the glass to be tested.

[0022] In the present invention, the base 1 is used as a base and is fixed to the workbench by bolts to ensure the overall horizontal state. The workbench 5 is a disc-shaped structure with an opening facing upward and is fixed to the central position of the base 1 by screws. A vertical column 2 is provided at the upper end of the base 1 and fixed by welding. A horizontally arranged connecting rod 3 is fixedly sleeved on the column 2, and a thickness detector 4 is connected to the extended end of the connecting rod 3.

[0023] The workbench 5 is equipped with a uniquely designed clamping assembly, which is specially used to accurately and stably clamp the glass to be tested, ensuring that the glass will not be displaced or shaken during the thickness detection process, thereby ensuring high accuracy of the test results.

[0024] A fixed block 6 is arranged at the central position of the workbench 5, wherein the outer edge of the fixed block 6 is provided with a plurality of notches to form a plurality of placement grooves 10, the opening size of the placement grooves 10 is adapted to the size of the glass to be tested, and the glass to be tested can be pre-clamped vertically therein. A fixed ring 7 with a ring diameter larger than the radius of the fixed block 6 is arranged on the periphery of the fixed block, and a through hole is provided on the fixed ring 7, and a butt plate 17 is fixedly arranged in the through hole, wherein the plate surface faces the placement groove 10 of the fixed block 6, and the butt plate 17 can reciprocate relative to the fixed ring 7 toward the placement groove 10 of the fixed block 6, so as to change the distance relative to the placement groove 10, so as to extend into the placement groove 10 to clamp and fix the glass to be tested. The detection head of the thickness detector 4 is aligned with the glass to be tested in the placement groove 10, so as to detect the thickness of the effective glass to be tested. After one detection is completed, the fixed plate 6 is rotated to release the butt plate 17, so as to drive an adjacent glass to be tested to rotate to the thickness detector 4 for subsequent detection. On the one hand, manual operation is not required, and on the other hand, the adjacent glass to be tested can be rotated and adjusted continuously for testing, and the continuous conversion can effectively liberate labor. Specifically, the rotation of the fixed block 6 can be controlled in real time by the motor. A stepper motor can be selected to effectively control the rotation angle of the fixed block 6, so that the thickness of each glass to be tested in the placement slot 10 can be accurately tested.

[0025] Specifically, the inner wall of the placement groove 10 is made of a special soft material or surface treatment process, which can effectively prevent the glass from being scratched during the placement process and provide a certain friction force to preliminarily fix the position of the glass.

[0026] Furthermore, a moving rod 13 is provided on one side of the abutment plate 17, and the moving rod 13 penetrates the side wall of the fixing ring 7 and is slidably connected thereto; The clamping assembly further comprises: A rotating ring 12 is rotatably connected to the workbench 5 and is covered on the periphery of the fixed ring 7. The ring diameter of the rotating ring 12 is larger than the ring diameter of the fixed ring 7. The arc-shaped slider 16 is disposed on the inner ring wall of the rotating ring 12 and between the rotating ring 12 and the fixed ring 7 . The arc-shaped slider 16 is used to squeeze the moving rod 13 to move into the placement groove 10 when the rotating ring 12 rotates.

[0027] In the present invention, the rotating ring 12 is arranged outside the fixed ring 7. There is a gap between the two rings, and an arc-shaped slider 16 is arranged on the inner wall of the rotating ring 12. Through the arc surface of the arc-shaped slider 16, the extrusion moving rod 13 can be driven by the abutment plate 17 to move toward the placement groove 10 during the rotation of the rotating ring 12, so that the glass to be tested can be squeezed and clamped, and the glass to be tested can be quickly fixed.

[0028] Furthermore, a spring 14 is sleeved on the outer side of the moving rod 13 , and two sides of the spring 14 are respectively connected to the moving rod 13 and the side wall of the fixing ring 7 .

[0029] In the present invention, a spring 14 is sleeved on the outer side of the moving rod 13, wherein the two ends of the spring 14 are fixedly connected to the side wall of the moving rod 13 and the fixing ring 7. In another preferred mode, a retaining ring 15 is provided on the side of the moving rod 13 away from the abutment plate 17, and the spring 14 is sleeved in the moving rod 13 inside the retaining ring 15, wherein the two ends of the spring 14 do not need to be welded or connected in a fixed manner, and the two ends of the spring 14 are respectively abutted against the side wall of the fixing ring 7 and the retaining ring 15. The abutment plate 17 is in the shape of a square plate, and its bottom side wall is in contact with the side wall of the workbench 5 or has a small spacing therebetween, thereby effectively preventing the abutment plate 17 from deflecting in the through hole and preventing it from smoothly entering the placement groove 10.

[0030] Furthermore, a curved surface is provided on one side of the curved slider 16 close to the fixed ring 7 , and the curved surface gradually bends and extends from the connection with the rotating ring 12 to the side close to the fixed ring 7 , and the extending direction of the curved surfaces of each curved slider 16 is consistent.

[0031] In the present invention, the arc surface of the arc slider 16 is gradually fully formed from the side wall of the rotating ring 12 to one side, and then the height of the two sides gradually changes. Among them, the spacing of the arc slider 16 is the same as the spacing of each placement groove 10. By rotating the rotating ring 12, the corresponding abutment plate 17 can be automatically pressed, so that the moving rod 13 slides in the through hole and gradually squeezes and fixes the glass to be tested in the placement groove 10. In addition, in another preferred embodiment, after the detection is completed, the rotating ring 12 is rotated in the opposite direction. Under the action of the spring 14, the moving rod 13 and the abutment plate 17 return to the initial position, and the detected glass can be taken out, and the detection operation of the next glass can be carried out.

[0032] Specifically, this arc surface design enables the arc-shaped slider 16 to transfer force to the moving rod 13 more steadily and smoothly when squeezing the moving rod 13, avoiding the problem of poor movement of the abutment plate 17 or loose clamping of the glass due to uneven force transmission. At the same time, the arc surface design also reduces the friction between the arc-shaped slider 16 and the moving rod 13, prolongs the service life of the device, and improves the overall performance and reliability of the device.

[0033] Furthermore, a plurality of anti-skid grooves 9 are arranged at intervals on the outer side of the rotating ring 12 , and the notch of each anti-skid groove 9 has a chamfer, and the notch of the anti-skid groove 9 contacts the workbench 5 .

[0034] In the present invention, a plurality of anti-skid grooves 9 are provided on the outer wall of the swivel 12, wherein the groove side walls of the anti-skid grooves 9 are provided with chamfers, which protrude outwardly and protrude from the original outer peripheral wall of the swivel 12. Therefore, during the rotation of the swivel 12, the rotation smoothness of the swivel 12 can be reduced. The existence of the chamfers on the anti-skid grooves 9 can contact with the surrounding walls of the workbench 5, thereby maintaining a temporary position limiting effect after the swivel 12 is rotated to a specific position.

[0035] In the process that the arc-shaped slider 16 rotates to contact and squeeze the rod head of the moving rod 13, the expansion and contraction amount of the spring 14 can ensure that the arc-shaped slider 16 can pass smoothly.

[0036] Furthermore, the size of the slot of the placement slot 10 is equal to the length of the abutment plate 17 .

[0037] In the present invention, by limiting the notch of the placement groove 10 to match the length of the abutment plate 17 , it can be ensured that the abutment plate 17 can smoothly enter the placement groove 10 .

[0038] Furthermore, an annular slide groove 8 is provided at the bottom of the workbench 5 , and a damping sliding connection is provided between the annular slide groove 8 and the rotating ring 12 .

[0039] In the present invention, an annular chute 8 is provided on the workbench 5, and the swivel 12 is mounted on the annular chute 8 for rotational connection. The annular chute 8 is C-shaped in the longitudinal section in the direction of rotation of the swivel 12, and the swivel 12 is inserted into the annular chute 8, and the bottom of the inserted portion has a baffle that limits its separation from the annular chute 8. This ensures that the swivel 12 can be effectively assembled in the annular chute 8.

[0040] Furthermore, the bottom of the placement groove 10 is recessed inward to form an arc-shaped groove 11 .

[0041] In the present invention, the bottom of the placement groove 10 is gradually sunken inward to form a corresponding groove, namely, an arc groove 11. The existence of the arc groove 11 can ensure that the glass to be tested will not completely collide with the placement groove 10, thereby facilitating placement and removal.

[0042] Furthermore, the height of the rotating ring 12 is greater than the horizontal height of the moving rod 13 .

[0043] In the present invention, the height of the rotating ring 12 needs to be higher than the horizontal height of the moving rod 13, so that the side wall of the rotating ring 12 can effectively surround and limit the moving rod 13 to prevent the moving rod 13 from escaping from the limit of the rotating ring 12 and the arc-shaped slider 16.

[0044] In the present invention, the glass to be tested is fixed on the workbench 5, and the workbench 5 is placed under the thickness detector 4, so that the thickness detector 4 can detect the thickness of the glass; the glass to be tested is placed in a plurality of placement slots 10 provided on the workbench 5, and the rotating ring 12 is rotated, and the arc-shaped slider 16 fixedly connected to the inner side wall of the rotating ring 12 rotates accordingly. Due to the curvature setting of the arc-shaped slider 16, when the arc-shaped slider 16 rotates, it will push the moving rod 13 to move to the inner side of the fixed ring 7, thereby pushing the abutment plate 17 to clamp the glass in the placement slot 10, and realize the clamping function of the glass; when the detection is completed, the rotating ring 12 is rotated, and at this time, the moving rod 13 is moved away from the placement slot by the elastic force of the spring, thereby releasing the clamping of the glass, and the next batch of glass is tested.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
