Description

Technical Field

[0001] This application relates to the field of glass production equipment technology, and in particular to an online thickness measuring device for a glass production line. Background Technology

[0002] In the glass processing industry, with continuous technological advancements, the applications of glass are becoming increasingly widespread, and the requirements for glass quality are also rising. Post-processing of glass, as a crucial link in ensuring the final quality of glass, encompasses multiple steps including precision cutting, grinding, cleaning, defect inspection, and packaging. The improvement and optimization of these processes have greatly enhanced the performance and appearance of glass products, enabling them to meet the needs of various industries and scenarios. For example, in the construction industry, high-quality glass provides better lighting and heat insulation; in the electronics industry, precise dimensions and good surface quality of glass are essential for display effects. The synergistic development of this series of processes has driven the continuous development and progress of the glass industry.

[0003] In the past, glass thickness was typically measured using a sampling method during post-processing. Sampling was usually conducted at regular intervals, involving placing the sampled glass on a coordinate measuring machine (CMM) for inspection. If thickness issues were found, the sampling frequency was increased, requiring personnel to re-inspect the problematic glass. Additionally, manual observation could be used to help determine the general condition of the glass.

[0004] Traditional sampling inspection methods have significant drawbacks regarding the aforementioned technologies. Because they don't inspect all products, thickness issues that may arise during the interval between inspections are easily missed. Furthermore, the feedback cycle is long; by the time a thickness deviation is detected, a certain number of defective products have already been produced, hindering timely adjustments to the production process to correct the thickness error. Therefore, reducing missed inspections during glass thickness testing and improving the glass pass rate has become an urgent problem to solve. Utility Model Content

[0005] In order to reduce the occurrence of missed detections during glass thickness testing and improve the glass pass rate, this application provides an online thickness measuring device for glass production lines.

[0006] This application provides an online thickness measuring device for a glass production line, which adopts the following technical solution:

[0007] An online thickness measuring device for a glass production line includes a mounting box, a cutting unit, a detection unit, and a first drive assembly;

[0008] Both the cutting unit and the detection unit are mounted on the mounting box. The cutting unit is used to cut glass. The cutting unit and the detection unit are spaced apart along a first direction. The detection unit includes a connecting plate and a color laser coaxial displacement meter. The connecting plate is detachably connected to the mounting box, and the color laser coaxial displacement meter is mounted on the connecting plate.

[0009] The first drive component includes a first guide rail, the length direction of which is parallel to a first direction, and the mounting housing is directly or indirectly slidably connected to the first guide rail along the first direction.

[0010] By adopting the above technical solution, the cutting unit and the detection unit are set on the mounting box, which is slidably connected to the first guide rail along the first direction. The mounting box synchronously drives the cutting unit and the detection unit to move along the first direction. Thus, in the early production line stage, while the glass is being cut, the thickness of the glass can be detected by a color laser coaxial displacement meter, realizing the online detection function of glass production. This allows changes in glass thickness to be promptly fed back to the front-end production process for adjustment, effectively improving the yield rate. At the same time, it reduces the waste of glass from random inspection and reduces the workload of personnel. The detection at the production line stage is a full inspection method, which effectively improves the quality of products compared to random inspection.

[0011] Optionally, the connecting plate has a first mounting hole through it in a third direction to accommodate the color laser coaxial displacement meter, and the color laser coaxial displacement meter is inserted into the first mounting hole.

[0012] By adopting the above technical solution, a first mounting hole is provided to insert the color laser coaxial displacement meter into the first mounting hole; the color laser coaxial displacement meter is positioned and installed by the first mounting hole.

[0013] Optionally, the connecting plate includes two connecting parts, which are detachably connected, and the connecting parts are distributed around the outer periphery of the first mounting hole along the circumferential direction of the first mounting hole;

[0014] It also includes two locking bolts, which are spaced apart on the connecting part along a first direction. One end of each locking bolt passes through one of the connecting parts and is threaded to the other connecting part.

[0015] By adopting the above technical solution, after inserting the color laser coaxial displacement meter into the first mounting hole by setting a locking bolt, the locking bolt is rotated to fix the two connecting parts, thereby achieving the fixation of the color laser coaxial displacement meter.

[0016] Optionally, the bottom wall of the mounting box is provided with a protective cavity along the first direction, and the color laser coaxial displacement meter is located inside the protective cavity.

[0017] By adopting the above technical solution, a protective cavity is opened in the bottom wall of the mounting box to protect the color laser coaxial displacement meter.

[0018] Optionally, the first drive assembly further includes a first mounting base, a first lead screw, and a first slider. The first mounting base is disposed on the first guide rail and connected to the mounting housing. The first slider is directly or indirectly connected to the bottom wall of the first mounting base and slides along the length direction of the first guide rail. The first lead screw is rotatably connected to the first guide rail. The axis of the first lead screw and its rotation axis are both parallel to the first direction. The first slider is sleeved on the first lead screw and slides along the length direction of the first lead screw.

[0019] By adopting the above technical solution, in order to drive the mounting box to slide along the first direction, a first lead screw is set. The rotation of the first lead screw drives the first slider to slide, thereby driving the first mounting base and the mounting box to slide along the first direction, so as to realize the sliding of the cutting unit and the detection unit along the first direction, so that the cutting unit and the detection unit can cut the glass and detect its thickness.

[0020] Optionally, the mounting housing is slidably connected to the first mounting base along the second direction.

[0021] By adopting the above technical solution, in order to enable the cutting unit to cut the glass in multiple directions, the mounting box is slidably connected to the first mounting base along the second direction, so as to realize the synchronous sliding of the cutting unit and the detection unit along the second direction.

[0022] Optionally, a second driving assembly is also included. The second driving assembly includes a second guide rail, a second slider, and a second lead screw. The second guide rail is disposed between the first slider and the first mounting base. The second guide rail is fixedly connected to the first slider. The length direction of the second guide rail and the axis of the second lead screw are both parallel to the second direction. The second lead screw is rotatably connected to the second guide rail. The axis of rotation of the second lead screw is parallel to the second direction. The second slider is fixedly connected to the bottom wall of the first mounting base. The second slider is sleeved on the second lead screw and slides along the length direction of the second lead screw.

[0023] By adopting the above technical solution, by setting a second driving component, the second lead screw rotates, and further drives the cutting unit and the detection unit to slide along the second direction through the second slider and the first mounting base.

[0024] Optionally, the connecting plate is slidably connected to the mounting box along the first direction.

[0025] By adopting the above technical solution, during the inspection, it is necessary to adjust the distance between the color laser coaxial displacement meter and the cutting unit to a suitable position. In order to facilitate the adjustment of the position of the color laser coaxial displacement meter, a connecting plate is slidably connected to the mounting box along the first direction, so that personnel can easily adjust the distance between the color laser coaxial displacement meter and the cutting unit.

[0026] Optionally, the mounting housing is slidably connected to the first mounting base along a third direction;

[0027] It also includes a third drive assembly, which comprises a third motor, a third lead screw, a third slider, and a third mounting base. The third mounting base is directly or indirectly fixedly connected between the mounting housing and the first mounting base. The third mounting base has a third sliding groove along a third direction on the side near the mounting housing. The third lead screw is located in the third sliding groove and is rotatably connected to the third mounting base. The axis of the third lead screw and its rotation axis are both parallel to the third direction. The third slider is sleeved on the third lead screw and slides along the axis of the third lead screw. One side of the third slider is fixedly connected to the mounting housing. The housing of the third motor is fixedly connected to the third mounting base. The output shaft of the third motor is coaxially fixedly connected to the third lead screw.

[0028] By adopting the above technical solution, by setting a third drive component, a third motor drives a third lead screw to rotate, and further drives the mounting box to slide in a third direction through a third slider, thereby driving the cutting unit to slide in a third direction, so as to realize the cutting unit to cut glass of different thicknesses.

[0029] Optionally, a fourth drive assembly is also included, the fourth drive assembly including a sliding seat and a screw, the sliding seat being slidably connected to the mounting housing along a first direction, the connecting plate being detachably connected to the sliding seat, the screw being rotatably connected to the mounting housing, the rotation axis of the screw being parallel to the first direction, and the sliding seat being sleeved on the screw and sliding along the length of the screw.

[0030] The mounting box is further provided with a fourth sliding groove along the first direction, and the sliding seat slides along the fourth sliding groove to guide the sliding of the sliding seat along the length of the screw rod.

[0031] By adopting the above technical solution and setting a fourth driving component, the screw is rotated, and the connecting plate is driven to slide along the first direction through the sliding seat, so that the position of the color laser coaxial displacement meter can be adjusted by the personnel.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. This application sets the cutting unit and the detection unit on the mounting box, and the mounting box is slidably connected to the first guide rail along the first direction. The mounting box synchronously drives the cutting unit and the detection unit to move along the first direction. Thus, in the early production line stage, while the glass is being cut, the thickness of the glass can be detected by a color laser coaxial displacement meter, realizing the online detection function of glass production. This allows changes in glass thickness to be fed back to the front-end production stage for process adjustment in a timely manner, effectively improving the yield rate. At the same time, it reduces the waste of glass from random inspection and reduces the workload of personnel. The detection at the production line stage is a full inspection method, which effectively improves the quality of products compared with random inspection.

[0043] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0044] This application discloses an online thickness measurement device for a glass production line. For ease of description, this application introduces directional terms such as first direction, second direction, and third direction to form a three-dimensional reference direction. The directional terms used, such as "first direction, second direction, and third direction," can be specifically referred to in the figure, where the first direction is represented by X, the second direction by Y, and the third direction by Z. The first direction, the second direction, and the third direction are perpendicular to each other.

[0045] Reference Figure 1 and Figure 2The online thickness measuring device for a glass production line includes a mounting housing 1, a cutting unit 2, a detection unit 3, and a first drive assembly 4. Both the cutting unit 2 and the detection unit 3 are mounted on the mounting housing 1, spaced apart along a first direction. The detection unit 3 includes a connecting plate 31 and a color laser coaxial displacement meter 32. The connecting plate 31 is detachably connected to the mounting housing 1, and the color laser coaxial displacement meter 32 is mounted on the connecting plate 31. The first drive assembly 4 includes a first guide rail 41, the length of which is parallel to the first direction. The mounting housing 1 is slidably connected to the first guide rail 41 along the first direction. In this embodiment, the color laser coaxial displacement meter 32 is a current technology in the field. The color laser coaxial displacement meter 32 uses white light as the measuring medium. Under a special lens group, white light will form a dispersion effect, and the measured object will reflect different colors of light at different depths, thereby measuring the distance and displacement from the probe to the surface of the measured object. In this field, the color laser coaxial displacement meter 32 can be used as a device for measuring glass thickness. The cutting unit 2 and the detection unit 3 are both mounted on the mounting box 1. The mounting box 1 slides along the first guide rail 41, which simultaneously drives the cutting unit 2 and the color laser coaxial displacement meter 32 to slide. This allows for the measurement of glass thickness during the early stage of glass processing, improving the yield rate, avoiding glass waste from manual sampling, and improving work efficiency.

[0046] Reference Figure 2 It should be noted that a working platform for placing glass is provided below the detection unit 3 and the cutting unit 2 (not shown in the figure). The cutting unit 2 includes a cutter head 21, which cuts the glass.

The detection unit 3 and the cutting unit 2 are both located in the protective cavity 11. One side of the cutter head 21 is located outside the protective cavity 11, and the other side is located inside the protective cavity 11. The mounting box 1 protects the color laser coaxial displacement meter 32.

[0048] Reference Figure 3To drive the mounting housing 1 to slide along a first direction, the first drive assembly 4 further includes a first mounting base 42, a first lead screw 43, a first slider 44, and a first motor 45. The first mounting base 42 is mounted on a first guide rail 41 and connected to the mounting housing 1. The first mounting base 42 and the mounting housing 1 are spaced apart along a second direction.

The first slider 44 is sleeved on the first lead screw 43 and slides along the axis of the first lead screw 43. The housing of the first motor 45 is fixedly connected to the first guide rail 41. The output shaft of the first motor 45 is coaxially fixedly connected to the first lead screw 43. When the first motor 45 is started, the first motor 45 drives the first lead screw 43 to rotate, which drives the first slider 44 to slide, thereby driving the first mounting base 42 and the mounting box 1 to slide along the first direction, so as to realize the sliding of the cutting unit 2 and the detection unit 3 along the first direction, so that the cutting unit 2 and the detection unit 3 can cut the glass and detect its thickness.

[0049] Reference Figure 3 To enable the cutting unit 2 to cut different parts of the glass, the mounting housing 1 is slidably connected to the first mounting base 42 along the second direction. To drive the mounting housing 1 to slide along the second direction, the online thickness measuring device for the glass production line also includes a second drive assembly 6. The second drive assembly 6 includes a second guide rail 61, a second slider 62, a second lead screw 63, and a second motor 64. The second guide rail 61 is fixedly connected to the top wall of the first slider 44 and is located between the first slider 44 and the first mounting base 42. The second slider 62 is fixedly connected to the bottom wall of the first mounting base 42. The length direction of the second guide rail 61 and the axis of the second lead screw 63 are both parallel to the second direction. The second guide rail 61 has a second groove 611 along the second direction for the second slider 62 to slide. The second lead screw 63 is rotatably connected to the second guide rail 61, and the rotation axis of the second lead screw 63 is parallel to the second direction. The second slider 62 is sleeved on the second lead screw 63 and slides along the axial direction of the second lead screw 63. The second lead screw 63 is located in the second groove 611. The housing of the second motor 64 is fixedly connected to the second guide rail 61, and the output shaft of the second motor 64 is coaxially fixedly connected to the second lead screw 63. When the second motor 64 is started, it drives the second lead screw 63 to rotate, and further drives the cutting unit 2 and the detection unit 3 to slide along the second direction through the second slider 62 and the first mounting base 42.

[0050] Reference Figure 4To enable cutting glass of different thicknesses, the cutting unit 2 needs to be height-adjustable so that the cutter head 21 can fall to the required cutting height. Therefore, the mounting housing 1 is slidably connected to the first mounting base 42 along a third direction. To drive the mounting housing 1 to slide along this third direction, the online thickness measuring device for the glass production line also includes a third drive assembly 7. The third drive assembly 7 includes a third motor 71, a third lead screw 72, a third slider 73, a second mounting base 74, and a third mounting base 75. One end of the second mounting base 74 is fixedly connected to the first mounting base 42, and the other end is fixedly connected to the third mounting base 75. The mounting housing 1 is located on the side of the third mounting base 75 away from the second mounting base 74, and the third mounting base 75 is close to...

The third motor 71 drives the third lead screw 72 to rotate, further driving the mounting housing 1 to slide along the third direction.

[0051] Reference Figure 5 In order to better install the color laser coaxial displacement meter 32, the connecting plate 31 has a first mounting hole 311 through it in a third direction to accommodate the color laser coaxial displacement meter 32. The color laser coaxial displacement meter 32 is inserted into the first mounting hole 311. The color laser coaxial displacement meter 32 is positioned and installed by the first mounting hole 311. In this embodiment, the first mounting hole 311 is a circular hole.

[0052] Reference Figure 5 and Figure 6 After the color laser coaxial displacement meter 32 is inserted into the first mounting hole 311, in order to further fix it and ensure stability, the connecting plate 31 includes two connecting parts 312. The two connecting parts 312 are detachably connected and are distributed around the outer periphery of the first mounting hole 311. The online thickness measuring device for the glass production line also includes two locking bolts 5. The two locking bolts 5 are spaced apart on the connecting parts 312 along the first direction. One end of the locking bolt 5 passes through one connecting part 312 and is threaded to the other connecting part 312. After the color laser coaxial displacement meter 32 is inserted into the first mounting hole 311, the locking bolts 5 are rotated to fix the two connecting parts 312, thereby fixing the color laser coaxial displacement meter 32.

[0053] Reference Figure 6 and Figure 7 During testing, the distance between the color laser coaxial displacement gauge 32 and the cutter head 21 needs to be adjusted to a suitable position. To facilitate the adjustment of the position of the color laser coaxial displacement gauge 32, the online thickness measuring device for the glass production line also includes a fourth drive assembly 8. The fourth drive assembly 8 includes a sliding seat 81 and a screw 82. The sliding seat 81 is slidably connected to the mounting housing 1 along the first direction. The connecting plate 31 is fixed to the sliding seat 81 by bolts. Specifically, one side of one of the connecting parts 312 is integrally connected to a mounting plate 33. The mounting plate 33 and the connecting part 312 form a plate structure with an L-shaped cross section. The mounting plate 33 is fixed to the sliding seat 81 by bolts. The rod 82 is rotatably connected to the mounting housing 1. The rotation axis of the screw 82 is parallel to the first direction.

One side of the sliding seat 81 is located in the fourth sliding groove 12 and slides along the first direction. When the screw 82 is rotated, the sliding seat 81 slides along the length of the screw 82, which further drives the color laser coaxial displacement meter 32 to slide, making it convenient for personnel to adjust the position.

[0054] The implementation principle of the online thickness measuring device for a glass production line according to the present application embodiment is as follows: the first motor 45 and the second motor 64 are driven to drive the detection unit 3 and the cutting unit 2 to slide along the first direction and the second direction through the first lead screw 43 and the second lead screw 63. The cutting unit 2 cuts the glass, and the color laser coaxial displacement meter 32 detects the thickness of the glass.

When it is necessary to adjust the color laser coaxial displacement meter 32, rotate the screw 82 to drive the sliding seat 81 to slide along the first direction, and further drive the color laser coaxial displacement meter 32 to slide along the first direction through the connecting plate 31 to adjust the distance between the color laser coaxial displacement meter 32 and the cutting unit 2.
