Description

Technical Field

[0001] This utility model relates to the field of glass thickness detection technology, and in particular to a glass thickness detection instrument. Background Technology

[0002] Glass is an inorganic non-metallic material that is hard, has excellent light transmission, and is chemically stable. The thickness of glass is crucial to ensuring the quality of glass products and the normal operation of related equipment and projects. As a result, glass thickness testing instruments have become indispensable tools in industrial production and quality control.

[0003] Traditional glass thickness testing instruments consist of a base, a column, a testing head, and a data display screen. In use, the glass to be tested is first placed stably on the base. Then, the height and horizontal position of the testing head are adjusted using the column to align it with the testing point on the glass. The instrument is then started, the testing head emits a testing signal, which is received after reflection by the glass, and finally, the glass thickness value is displayed on the data display screen. However, the various components of the instrument are fixed together by welding or multiple bolts. When the instrument malfunctions and requires repair or replacement of parts, the disassembly process is extremely difficult, severely impacting repair efficiency and the instrument's lifespan.

[0004] To address the aforementioned problems of traditional instruments, existing technologies design the column as a telescopic structure to simplify calibration procedures and use snap-fit ​​connections between the detection head and the column for easy disassembly and maintenance. However, in practical use, while the snap-fit ​​connection makes disassembly convenient, slight vibrations during testing can cause the snaps to loosen, leading to displacement of the detection head and resulting in an unstable instrument position, thus affecting testing accuracy. Furthermore, these improved structures lack an effective linkage and fixing mechanism, requiring operators to spend considerable time adjusting and securing the instrument's various parts before testing and constantly monitoring for displacement during the testing process. This instability in the instrument's position complicates the testing process and makes operation inconvenient. Therefore, a glass thickness testing instrument is proposed to solve these problems.

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.

[0033] See attached document Figure 1 Appendix Figure 2 and attached Figure 3 The present invention provides an embodiment of a glass thickness testing instrument, comprising a placement platform 1 for supporting the glass to be tested, a bracket 2 fixedly connected to the top rear side of the placement platform 1 for providing overall support for the device, a magnetic detection mechanism 5 provided on the rear side of the bracket 2 for detecting the thickness of bottle-type glass, a fixing plate 3 fixedly connected to the front side of the outer wall of the bracket 2 for mounting and fixing an optical detection mechanism 4, and an optical detection mechanism 4 provided on the front side of the fixing plate 3 for detecting the glass thickness optically.

[0034] The optical inspection mechanism 4 includes a mounting box 401. The rear side of the outer wall of the mounting box 401 is fixedly connected to the front side of the fixing plate 3. The mounting box 401 provides installation and sliding space for the optical inspection instrument 402 and the base 403. The optical inspection instrument 402 is slidably connected to the inner wall of the mounting box 401. The optical inspection instrument 402 measures the glass thickness by emitting and receiving detection beams. The base 403 is slidably connected to the inner wall of the mounting box 401. The base 403 is used to drive the base plate 406 to move up and down. L-shaped... The outer walls of the two L-shaped bars 404 are fixedly connected with springs 405. The springs 405 can provide elastic restoring force to reset the base 403. The bottom of the base 403 is fixedly connected with a base plate 406. The base plate 406 is used to install the clamping component 407 and support the optical detector 402. The clamping component 407 is provided on the front side of the base plate 406. The clamping component 407 is used to fix the optical detector 402. The support component 408 is provided on the front side of the bracket 2. The support component 408 is used to support and limit the base plate 406.

[0035] The clamping assembly 407 includes two bolts 4071. The outer walls of the two bolts 4071 are threaded to the inner wall of the base plate 406. The bolts 4071 are used to adjust the gap between the pressure plate 4072 and the base plate 406. The outer walls of the two bolts 4071 are threaded to the same pressure plate 4072. The pressure plate 4072 and the base plate 406 cooperate to clamp the optical detector 402.

[0036] The bottom support assembly 408 includes two rotating bars 4081. The tops of the two rotating bars 4081 are slidably connected to the bottom of the base plate 406. The rotating bars 4081 provide support and limit the base plate 406. Two rotating grooves 4082 are opened on the front side of the bracket 2. The rotating grooves 4082 are used to accommodate the rotating bars 4081 to release their support on the base plate 406.

[0037] Specifically, before testing, the device is in its initial state. The placement platform 1 is placed horizontally as the overall support base. The front side of the bracket 2 is fixed with the optical inspection mechanism 4 via the fixing plate 3, and the rear side is installed with the magnetic inspection mechanism 5 to achieve composite testing. In the optical inspection mechanism 4, the optical detector 402 is positioned by the mounting box 401. The inner wall of the mounting box 401 slides against the outer wall of the optical detector 402, allowing the optical detector 402 to move stably in the vertical direction. The bottom of the optical detector 402 passes through the base plate 406, and the base plate 406 is connected to the mounting plate 402 via the base support 403. Box 401 is slidably connected. The L-shaped strips 404 on the left and right sides of the base support 403 are fixed to one end of the spring 405, and the other end of the spring 405 is connected to the inner wall of the mounting box 401, forming an elastic support structure. During testing, the glass to be tested is placed on the placement platform 1, and the two rotating strips 4081 of the bottom support assembly 408 are rotated to engage with the rotating groove 4082 on the front side of the bracket 2. The support and limitation of the rotating strips 4081 on the base plate 406 are released, and the base plate 406 is pulled down, causing the base support 403 to move along the mounting box 401. 1. As the inner wall slides down, the spring 405 is stretched, generating elastic potential energy. When the detection end of the optical detector 402 is close to the glass surface, the optical detector 402 emits a detection beam and receives the reflected signal, realizing optical detection of the glass thickness. After the detection is completed, under the elastic restoring force of the spring 405, the base support 403 drives the base plate 406 to return to its original position, rotating the two rotating bars 4081 out of the rotating groove 4082. The rotating bars 4081 support and limit the base plate 406, fixing the position of the optical detector 402. When replacing or repairing the optical detector 402, rotate bolt 4071 to increase the gap between the base plate 406 and the pressure plate 4072, release the clamping constraint on the optical detector 402, and directly pull out the optical detector 402 for maintenance. After maintenance, reinsert the optical detector 402 into the base plate 406, tighten the two bolts 4071 on the base plate 406, so that the pressure plate 4072 and the base plate 406 cooperate to clamp the outer wall of the optical detector 402, completing the rigid fixation of the optical detector 402 and restoring the detection state.

[0038] See attached document Figure 4 and attached Figure 5The magnetic detection mechanism 5 includes a rotating base 501, which is used to install a telescopic hose 502 and rotate to adjust its direction. The outer wall of the rotating base 501 is rotatably connected to the inner wall of the bracket 2, so that the rotating base 501 can rotate relative to the bracket 2. The telescopic hose 502 is slidably connected to the inner wall of the rotating base 501. The telescopic hose 502 can extend and retract to adjust the position of the probe head 503. The probe head 503 is fixedly connected to the outer wall of the telescopic hose 502. The probe head 503 is used to detect the thickness of the glass by magnetic induction. Multiple pins 504 are fixedly connected to the outer wall of the probe head 503. Multiple pin holes 505 are opened on the outer wall of the rotating base 501. The pin holes 505 cooperate with the pins 504 to achieve positioning. A locking component 506 is provided on the rear side of the bracket 2. The locking component 506 is used to fix the position of the rotating base 501. A storage component 507 is provided on the rear side of the bracket 2. The storage component 507 is used to store magnetic beads 5073.

[0039] The locking assembly 506 includes a locking bar 5061, the outer wall of which is rotatably connected to the rear side of the bracket 2, so that the locking bar 5061 can rotate to lock or unlock. A locking seat 5062 is fixedly connected to the rear side of the bracket 2, and the locking seat 5062 is used to cooperate with the locking bar 5061 to complete the locking.

[0040] The storage component 507 includes a storage box 5071. The front side of the storage box 5071 is fixedly connected to the rear side of the bracket 2. The storage box 5071 provides installation space for the slide drawer 5072. The slide drawer 5072 is slidably connected to the inner wall of the storage box 5071. The slide drawer 5072 is used to place magnetic beads 5073 and is easy to put in and take out. Multiple magnetic beads 5073 are slidably connected to the inner wall of the slide drawer 5072. The magnetic beads 5073 are used to cooperate with the probe head 503 to form a magnetic field to detect thickness.

[0041] Specifically, when testing the thickness of glass bottles and jars, the glass container to be tested is placed on the placement platform 1. A matching magnetic bead 5073 is taken from the slide drawer 5072 of the storage component 507 and placed inside the glass container. The locking bar 5061 is rotated to disengage it from the locking seat 5062, releasing the locking component 506 from fixing the rotating base 501. The rotating base 501 is then rotated downwards so that the probe 503 faces forward and aligns with the glass container on the placement platform 1. The probe 503 is then pulled out from the rotating base 501 and brought close to the outer wall of the glass container. At this point, the pin on the outer wall of the probe 503... 504 disengages from the corresponding pin hole 505 on the rotary seat 501, and the telescopic hose 502 on the inner wall of the rotary seat 501 is stretched. During the test, the probe 503 forms a magnetic field coupling with the magnetic bead 5073 in the container through the principle of magnetic induction. The thickness of the bottle wall is calculated by the change in magnetic field strength. After the test is completed, the pin 504 is inserted into the pin hole 505, the telescopic hose 502 is retracted into the rotary seat 501, the rotary seat 501 is rotated upward to reset, the locking bar 5061 is rotated to engage with the locking seat 5062 to complete the locking, and the magnetic bead 5073 is placed back into the slide drawer 5072 for storage.

[0042] See attached document Figure 1 and attached Figure 2 A soft pad 6 is fixedly connected to the top of the placement platform 1. The soft pad 6 is used to buffer the contact between the glass to be tested and the placement platform 1 to avoid scratches. Multiple anti-slip strips 7 are fixedly connected to the left and right sides of the top of the placement platform 1. The anti-slip strips 7 are used to increase the friction between the glass and the placement platform 1 to prevent the glass from sliding. Pad feet 8 are fixedly connected to the four corners of the bottom of the placement platform 1. The pad feet 8 are used to support the placement platform 1 and enhance its placement stability. A display screen 9 is fixedly connected to the top of the bracket 2. The display screen 9 is used to display the detected glass thickness data and related information.

[0043] Specifically, the soft pad 6 on the top of the placement platform 1 prevents the glass to be tested from being scratched when it comes into contact with the platform, the multiple anti-slip strips 7 on the top left and right sides increase the friction between the glass and the placement platform 1 and prevent the glass from sliding, the pads 8 at the four corners of the bottom provide support and enhance placement stability, and the display screen 9 on the top of the bracket 2 is used to display the detected glass thickness data and related information.

[0044] Working principle: Before testing, the device is in its initial state. The placement platform 1 is placed horizontally as the overall support base. The front side of the bracket 2 is rigidly fixed to the optical inspection mechanism 4 by the fixing plate 3, while the rear side is equipped with the magnetic inspection mechanism 5 to cooperate in completing the composite inspection. The core detection component of the optical inspection mechanism 4, the optical detector 402, is positioned by the mounting box 401. The inner wall of the mounting box 401 slides against the outer wall of the optical detector 402 to ensure that the optical detector 402 moves stably in the vertical direction. The bottom of the optical detector 402 passes through the base plate 406, which is supported by a base bracket. 403 and mounting box 401 form a sliding connection. The L-shaped strips 404 on the left and right sides of the base 403 are fixed to one end of the spring 405, and the other end of the spring 405 is connected to the inner wall of the mounting box 401, forming an elastic support structure. During testing, the operator places the glass to be tested stably on the placement platform 1, rotates the two rotating strips 4081 in the base support assembly 408, so that they are engaged in the rotating groove 4082 on the front side of the bracket 2. At this time, the bottom support and limit of the rotating strips 4081 on the bottom plate 406 are released, and the bottom plate 406 is pulled down, driving the bottom plate 406 to move ... The support 403 slides down the inner wall of the mounting box 401, and the spring 405 is stretched to generate elastic potential energy. When the detection end of the optical detector 402 is close to the glass surface, the optical detector 402 emits a detection beam and receives the reflected signal to achieve optical detection of the glass thickness. After the detection is completed, under the elastic restoring force of the spring 405, the support 403 drives the base plate 406 to return to its original position, rotating the two rotating bars 4081 out of the rotating groove 4082. At this time, the rotating bars 4081 provide support and limit for the base plate 406, thereby fixing the optical detector 402. When the optical detector 402 needs to be replaced or repaired, rotate the bolt 4071 to increase the gap between the base plate 406 and the pressure plate 4072, thereby releasing the clamping constraint on the optical detector 402. At this time, the optical detector 402 can be pulled out directly for maintenance. After maintenance, the optical detector 402 is reinserted into the base plate 406, and then the two bolts 4071 on the base plate 406 are tightened so that the pressure plate 4072 and the base plate 406 cooperate to clamp the outer wall of the optical detector 402, thereby completing the rigid fixation of the optical detector 402 and restoring the detection state.

[0045] Furthermore, when it is necessary to test the thickness of glass bottles and jars, first place the glass container to be tested on the placement platform 1, take out the appropriate magnetic bead 5073 from the slide drawer 5072 of the storage component 507, place it inside the glass container, rotate the locking bar 5061 to disengage it from the locking seat 5062, release the locking component 506 from fixing the rotating base 501, rotate the rotating base 501 downwards so that the probe head 503 faces forward and is aligned with the glass container on the placement platform 1, pull the probe head 503 out of the rotating base 501 and close to the outer wall of the glass container. During this process, the pin 504 on the outer wall of the probe head 503... The telescopic hose 502 on the inner wall of the rotating base 501 is stretched after disengaging from the corresponding pin hole 505 on the rotating base 501. During testing, the probe 503 forms a magnetic field coupling with the magnetic bead 5073 in the container through the principle of magnetic induction. The thickness of the bottle wall is calculated by the change in magnetic field strength. After the test is completed, the pin 504 is inserted into the pin hole 505, and the telescopic hose 502 is retracted into the rotating base 501. The rotating base 501 is rotated upward to reset, and then the locking bar 5061 is rotated to lock into the locking seat 5062 to complete the locking. Finally, the magnetic bead 5073 is put back into the slide drawer 5072 for storage, ensuring that the components are in orderly place.
