Description

Technical Field

[0001] This invention relates to the field of laser measurement technology, specifically to an SMC sheet thickness detection device. Background Technology

[0002] SMC sheet, or sheet molding compound, is a glass fiber reinforced thermosetting composite material. Due to its excellent mechanical properties, molding efficiency, and corrosion resistance, it is widely used in the automotive, building materials, and electrical industries. Thickness is a core indicator for measuring the molding quality of SMC sheets, directly determining the dimensional accuracy and assembly performance of subsequent molded products. SMC sheet thickness detection devices are specialized testing equipment designed for this type of sheet. They typically use laser sensors as the core detection component, working in conjunction with a support structure to achieve the load-bearing positioning of the SMC sheet. Through non-contact distance measurement of the sheet surface using corresponding laser sensors positioned above and below, the sheet thickness data is calculated. This is a key piece of equipment in the SMC sheet production process to ensure product quality, effectively replacing traditional manual inspection and improving inspection efficiency and data accuracy.

[0003] In current SMC sheet thickness detection devices, the support structure bearing the SMC sheet needs to withstand the static load of the SMC sheet for a long time. The metal frame is prone to creep deformation. At the same time, the continuous vibration generated by the operation of the production equipment in the workshop will cause the connecting bolts and other connecting parts of the support structure to gradually loosen. All of these will cause the support structure to deviate from its initial horizontal state. Therefore, the tilt of the support structure will directly cause the SMC sheet inside it to tilt synchronously, which will cause the detection optical path of the laser sensor to be unable to keep perpendicular to the surface of the sheet. In addition, after the support structure tilts, it is not easy to detect in time, which will affect the subsequent detection results.

[0004] To address the above issues, an SMC sheet thickness detection device is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide an SMC sheet thickness detection device. By using this invention, the problems mentioned above are solved, such as the support structure being prone to deformation, causing it to deviate from its initial horizontal state, resulting in the laser sensor's detection optical path not being perpendicular to the sheet surface, and the inability to perform timely detection after the support structure tilts, thus affecting subsequent detection results.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An SMC sheet thickness detection device includes a detection frame, a translation component disposed within the detection frame, a thickness measuring component disposed on one side of the translation component, a rotation component disposed within the detection frame, a fixing component disposed within the rotation component, a driving component disposed within the rotation component, a detection component disposed on one side of the driving component, a receiving component disposed at the bottom of the rotation component, a pushing component disposed on the outer wall of the detection component, the pushing component being connected to the rotation component, and a locking component disposed within the rotation component.

[0007] Furthermore, the translation component includes a mounting base fixedly connected within the detection frame. A first servo motor is mounted on one side of the mounting base. A threaded rod is fixedly connected to the output end of the first servo motor. The threaded rod is rotatably connected to the mounting base. A threaded block is threadedly connected to the outer wall of the threaded rod. A U-shaped mounting plate is fixedly connected to one side of the threaded block.

[0008] Furthermore, the thickness measurement component includes an upper laser sensor and a lower laser sensor that are fixedly connected to one side of the U-shaped mounting plate.

[0009] Furthermore, the rotating assembly includes a support frame fixedly connected to the detection frame, a limiting ring fixedly connected to the top of the support frame, a rotating plate rotatably connected inside the limiting ring, a placement groove extending through the rotating plate, and a first slot and a second slot extending through the inner wall of the limiting ring.

[0010] Furthermore, the fixing component includes a limiting plate fixedly connected to the placement groove, and an L-shaped sliding plate slidably connected to the other side of the placement groove. A plurality of first springs are fixedly connected to one side of the L-shaped sliding plate, and the other ends of the plurality of first springs are fixedly connected to the inner wall of the rotating plate.

[0011] Furthermore, the drive assembly includes a U-shaped support plate fixedly connected to the support frame, a second servo motor installed inside the U-shaped support plate, a rotating shaft fixedly connected to the output end of the second servo motor, the rotating shaft being rotatably connected to the U-shaped support plate, and a connecting frame fixedly connected to one end of the rotating shaft.

[0012] Furthermore, the detection assembly includes a support ring fixedly connected to one end of a connecting frame, a gear ring fixedly connected to the top of the support ring, a rotating ring rotatably connected to the top of the support ring, a dual-axis motor installed inside the rotating ring, a first connecting shaft fixedly connected to one output end of the dual-axis motor, a gear fixedly connected to one end of the first connecting shaft, the gear meshing with the gear ring, a second connecting shaft fixedly connected to the other output end of the dual-axis motor, and a detection plate fixedly connected to the outer wall of the second connecting shaft.

[0013] Furthermore, the receiving component includes a bearing ring fixedly connected to the bottom of the rotating plate, and a detection ring fixedly connected inside the bearing ring.

[0014] Furthermore, the pushing assembly includes a push rod fixedly connected to the outer wall of the support ring, and a driven rod fixedly connected to the bottom of the rotating plate, with the push rod and the driven rod in contact.

[0015] Furthermore, the snap-fit ​​assembly includes a second spring fixedly connected inside the rotating plate, and a snap-fit ​​rod is fixedly connected to the other end of the second spring, the snap-fit ​​rod being slidably connected to the rotating plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: By combining the translation component and the thickness measurement component, the linear translation adjustment of the thickness detection points in different areas of the SMC sheet can be realized. The laser emission structure arranged vertically accurately collects the distance data between the upper and lower surfaces of the sheet, and the controller quickly calculates the real-time thickness. Non-contact detection avoids damage to the sheet and improves the accuracy and stability of the basic thickness detection. By setting up fixed and rotating components, SMC sheets can be lightly pressed and detachably fixed, effectively limiting displacement, warping and movement of the sheets during the inspection process, ensuring that the inspection position remains stable, and providing solid support for subsequent multi-point and all-round thickness inspection. By cooperating with the drive component, detection component and receiving component, the levelness of the rotating component can be automatically and comprehensively detected, replacing manual operation with a handheld level. It can intelligently judge abnormal tilt of the rotating component and alarm in time, avoiding the disadvantages of low efficiency and accuracy affected by human factors in manual detection, and improving the convenience and timeliness of levelness detection. By combining the detection component with the thickness measurement component, the online automated calibration of the thickness measurement component can be completed intelligently without stopping the machine to disassemble the equipment or manually calibrating it. It can also determine sensor offset and loose installation issues, ensure accurate and stable detection data, reduce equipment downtime losses, and adapt to the needs of continuous industrial production. By cooperating with the push component and the snap-fit ​​component, the SMC sheet can be driven to rotate synchronously in the circumferential direction. With the thickness measurement component, real-time detection of multiple points in the circumferential direction can be achieved. Multiple sets of data are integrated to calculate the accurate average thickness, eliminating the random error of single-point detection, intuitively reflecting the uniformity of the sheet's circumferential thickness, and improving the accuracy of single detection. By coordinating the drive components, snap-fit ​​components, and translation components, it is possible to achieve radial and circumferential dual-dimensional coverage inspection of SMC sheets, further expanding the inspection points, reducing blind spots, and collecting thickness data of multiple areas of the sheet from multiple directions. This breaks through the limitations of unidirectional local inspection, significantly improves the comprehensiveness of inspection, and meets the inspection requirements of high-quality SMC sheets.

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

[0020] To address the technical issues that arise from the support structure's tendency to deform, causing the laser sensor's detection optical path to deviate from the sheet surface, and hindering timely detection when the support structure tilts, thus affecting subsequent detection results, the following measures are proposed. Figures 1-12 As shown, the following preferred technical solutions are provided: like Figure 1 As shown, an SMC sheet thickness detection device includes a detection frame 1, which can support and fix various components. A controller is installed inside the detection frame 1, which can control various electrical components. The controller is existing technology and is not shown in the figure. A translation component 2 is set inside the detection frame 1, and a thickness measuring component 3 is set on one side of the translation component 2. The translation component 2 can drive the thickness measuring component 3 to move linearly along a preset path inside the detection frame 1, thereby adjusting the thickness detection points of different areas of the SMC sheet. The thickness measuring component 3 can emit lasers through corresponding laser emitting structures arranged above and below to collect the distance data between the upper and lower surfaces of the SMC sheet. The controller calculates the real-time thickness value of the sheet. A rotation component 4 is set inside the detection frame 1.

[0021] like Figure 3 As shown, a fixing component 5 is provided inside the rotating assembly 4. The fixing component 5 can lightly press and detachably fix the SMC sheet placed inside the rotating assembly 4, limiting the displacement, warping, and movement of the sheet during the testing process, and ensuring stable testing position. A driving component 6 is provided inside the rotating assembly 4, such as... Figure 4 As shown, a detection component 7 is provided on one side of the drive component 6. The detection component 7 can realize laser reflection and angle rotation adjustment respectively, and together with the thickness measurement component 3, it completes the levelness detection of the rotating component 4 and the self-calibration detection of the thickness measurement component 3. Figure 5 As shown, a receiving component 8 is provided at the bottom of the rotating component 4. The receiving component 8 can receive the reflected laser signal from the detection component 7, thereby making it easier to determine whether the rotating component 4 has tilted.

[0022] In use, the SMC sheet that needs to be thickness measured is placed in the rotating component 4 and then fixed by the fixing component 5. Then, the controller causes the thickness measuring component 3 to emit detection lasers to the upper and lower surfaces of the SMC sheet, which can collect the distance data between the upper and lower surfaces of the sheet and calculate the real-time thickness.

[0023] After a period of measurement, due to long-term load and equipment vibration, the rotating component 4 is prone to tilting. At this time, no SMC sheet is placed inside the rotating component 4. Then, the controller causes the drive component 6 to rotate the detection component 7, aligning the vertical position of the detection component 7 with that of the thickness measuring component 3. Subsequently, the controller causes the reflective structure inside the detection component 7 to rotate 45 degrees from the horizontal position. The laser emitted by the upper laser emitting structure inside the thickness measuring component 3 is reflected to the receiving component 8 through the reflective structure inside the detection component 7. Then, the rotation of the detection component 7 causes the reflective structure inside the detection component 7 to rotate axially, thereby detecting the levelness of the rotating component 4 in multiple directions. This allows for timely detection of tilting abnormalities of the rotating component 4. Compared with the existing detection using a level, this method can achieve automated and all-round detection of the levelness of the rotating component 4, eliminating the need for manual operation of the handheld device. This avoids the disadvantages of low efficiency and accuracy affected by human factors in manual detection, improving the convenience and timeliness of levelness detection. If the detection value is abnormal during the rotation detection process, an alarm will be triggered to remind the user to perform maintenance. The alarm is existing technology and is not shown in the figure.

[0024] After a period of measurement, the thickness measuring component 3 is prone to tilting due to long-term vibration and loose installation structure, leading to distortion and decreased accuracy of thickness detection data. At this point, the controller drives the drive component 6 to rotate the detection component 7, aligning its vertical position with that of the thickness measuring component 3. Then, the controller rotates the reflective structure within the detection component 7 from a 45-degree position to a horizontal position. Subsequently, the controller directs the lasers emitted by the upper and lower laser emitting structures within the thickness measuring component 3 to illuminate the upper and lower surfaces of the reflective structure within the detection component 7, respectively. The measured values ​​are then compared with the calibrated values. If a deviation exceeds the normal range, an alarm is triggered, prompting the user to perform maintenance. This allows for timely verification of the installation accuracy and detection precision of the thickness measuring component 3. Compared to existing technologies, this method enables automated online calibration of the thickness measuring component 3, eliminating the need for equipment disassembly or manual calibration. It avoids cumbersome manual calibration processes, reduces downtime losses, and accurately identifies sensor misalignment and loose installation, ensuring the accuracy and stability of thickness detection data and meeting the long-term testing needs of continuous industrial production.

[0025] like Figure 4 As shown, a pushing component 9 is provided on the outer wall of the detection component 7. The pushing component 9 is connected to the rotating component 4. A snap-fit ​​component 10 is provided inside the rotating component 4.

[0026] During the SMC sheet thickness detection process, the controller causes the drive component 6 to rotate forward, driving the push component 9 to move. This causes the push component 9 to synchronously rotate the SMC sheet to be measured within the rotating component 4. During rotation, the thickness measurement component 3 performs real-time multi-point measurements, collecting thickness data from circumferential points on the SMC sheet. This avoids the random errors of single-point detection. By integrating and calculating multiple sets of data, a precise average thickness is obtained, reflecting the uniformity of the sheet's circumferential thickness and improving the accuracy and comprehensiveness of a single detection. When the push component 9 begins to rotate, the locking structure within the locking component 10 engages from one of the locking points. After the slot is inserted into another slot, the thickness measurement component 3 pauses detection. Then, the translation component 2 moves the thickness measurement component 3 a short distance. After that, the drive component 6 rotates in the opposite direction, driving the push component 9 to move. Together with the thickness measurement component 3, it performs real-time multi-point measurement again, which can cover the SMC sheet in both radial and circumferential dimensions. This further expands the detection points, reduces the detection blind spots, and collects multi-area thickness data of the sheet from multiple directions. Compared with the limitations of existing technologies that perform unidirectional and local point detection, it can improve the comprehensiveness and accuracy of thickness detection and adapt to the detection needs of high-quality SMC sheets.

[0027] like Figure 2 and Figure 3 As shown, the translation component 2 includes a mounting base 21 fixedly connected to the detection frame 1. A first servo motor 22 is mounted on one side of the mounting base 21. A threaded rod 23 is fixedly connected to the output end of the first servo motor 22. The threaded rod 23 is rotatably connected to the mounting base 21. A threaded block 24 is threadedly connected to the outer wall of the threaded rod 23. A U-shaped mounting plate 25 is fixedly connected to one side of the threaded block 24.

[0028] The thickness measurement component 3 includes an upper laser sensor 31 and a lower laser sensor 32 that are fixedly connected to one side of the U-shaped mounting plate 25. The upper laser sensor 31 and the lower laser sensor 32 can emit detection lasers corresponding to each other, and respectively collect the distance signals between the upper and lower surfaces of the SMC sheet. The controller calculates the real-time thickness value of the SMC sheet by the distance difference. The upper laser sensor 31 and the lower laser sensor 32 are eccentrically set with the rotating component 4 to facilitate subsequent multi-point measurement.

[0029] like Figures 3-7 and Figures 10-12As shown, the rotating assembly 4 includes a support frame 41 fixedly connected to the detection frame 1. A limiting ring 42 is fixedly connected to the top of the support frame 41. A rotating plate 43 is rotatably connected inside the limiting ring 42. A placement groove 44 is provided through the rotating plate 43. A first slot 45 and a second slot 46 are provided on the inner wall of the limiting ring 42. The positions of the first slot 45 and the second slot 46 are offset from those of the upper laser sensor 31 and the lower laser sensor 32, which can avoid interference with the laser detection optical path, ensure the smooth flow of the thickness detection optical path and the stable operation of the locking action.

[0030] like Figure 4 and Figure 6 As shown, the fixing component 5 includes a limiting plate 51 fixedly connected to the placement groove 44, and an L-shaped slide plate 53 slidably connected to the other side of the placement groove 44. A plurality of first springs 52 are fixedly connected to one side of the L-shaped slide plate 53, and the other ends of the plurality of first springs 52 are fixedly connected to the inner wall of the rotating plate 43.

[0031] Before testing, the L-shaped slide plate 53 is pulled to compress the first spring 52. Then, the SMC sheet to be tested is placed in the placement groove 44, and one side of the placement groove 44 is inserted between the bottom of the limiting plate 51 and the top of the placement groove 44. The SMC sheet is then fixed by the first spring 52 resetting.

[0032] like Figure 3 , Figure 8 and Figure 10 As shown, the drive assembly 6 includes a U-shaped support plate 61 fixedly connected to the support frame 41. A second servo motor 62 is installed in the U-shaped support plate 61. A rotating shaft 63 is fixedly connected to the output end of the second servo motor 62. The rotating shaft 63 is rotatably connected to the U-shaped support plate 61. A connecting frame 64 is fixedly connected to one end of the rotating shaft 63.

[0033] like Figures 8-10As shown, the detection component 7 includes a support ring 71 fixedly connected to one end of a connecting frame 64. A gear ring 72 is fixedly connected to the top of the support ring 71, and a rotating ring 73 is rotatably connected to the top of the support ring 71. A dual-axis motor 74 is installed inside the rotating ring 73. The dual-axis motor 74 is a dual-output-shaft self-locking servo motor, capable of independently controlling two output shafts. The dual-axis motor 74 has a self-locking function. A first connecting shaft 75 is fixedly connected to one output end of the dual-axis motor 74. A gear 76 is fixedly connected to one end of the first connecting shaft 75, and the gear 76 meshes with the gear ring 72. A second connecting shaft 77 is fixedly connected to the other output end of the dual-axis motor 74. A detection device is fixedly connected to the outer wall of the second connecting shaft 77. The measuring plate 78 is made of highly reflective mirror material on both its upper and lower sides, which can reflect the laser emitted by the upper laser sensor 31 and the lower laser sensor 32 with high reflectivity, ensuring stable transmission and accurate reception of the laser signal. During initial calibration, the detection component 7 is first adjusted to the horizontal calibration position, so that the upper laser sensor 31, the lower laser sensor 32 and the detection plate 78 are aligned vertically. The position of the detection plate 78 is locked by the dual-axis motor 74, and the upper laser sensor 31 and the lower laser sensor 32 are started to collect the reference distance data of the upper and lower end faces of the detection plate 78. The controller sets this data as the calibration value. The reflective structure in the above-mentioned detection component 7 is the detection plate 78.

[0034] like Figure 7 As shown, the receiving component 8 includes a bearing ring 81 fixedly connected to the bottom of the rotating plate 43. A detection ring 82 is fixedly connected inside the bearing ring 81. The detection ring 82 is made of a high-sensitivity laser receiving material and can accurately receive the laser signal reflected by the detection plate 78 and convert the optical signal into an electrical signal to be transmitted to the controller.

[0035] In use, the SMC sheet that needs to be thickness measured is placed in the placement slot 44. Then, the SMC sheet is fixed by the limiting plate 51 in conjunction with the first spring 52 and the L-shaped sliding plate 53. After that, the controller causes the upper laser sensor 31 and the lower laser sensor 32 to emit detection lasers to the upper and lower surfaces of the SMC sheet respectively, which can collect the distance data between the upper and lower surfaces of the sheet and calculate the real-time thickness.

[0036] After a period of measurement, due to long-term load and equipment vibration, the limit ring 42 is prone to tilting. At this time, no SMC sheet is placed in the placement slot 44. Then, the controller drives the second servo motor 62 to drive the rotating shaft 63 and the connecting frame 64 to rotate, so that the support ring 71 and the detection plate 78 rotate synchronously, so that the horizontal position of the detection plate 78 corresponds to the vertical position of the upper laser sensor 31 and the lower laser sensor 32. Then, the controller drives the dual-axis motor 74 to drive the second connecting shaft 77 to rotate forty-five degrees, so that the detection plate 78 rotates synchronously forty-five degrees. At this time, the laser emitted by the upper laser sensor 31 is reflected by the detection plate 78 to the detection ring 82. Then, the dual-axis motor 74 drives the first connecting shaft 75 and the gear 76 to rotate, and the gear 76 meshes with the gear ring 72, so that... The rotating ring 73 rotates within the support ring 71, synchronously driving the second connecting shaft 77 and the detection plate 78 to rotate. This causes the detection plate 78 to rotate axially, uniformly reflecting the laser emitted by the upper laser sensor 31 to different positions of the detection ring 82. This allows for the detection of the levelness of the limiting ring 42 in multiple directions, enabling timely detection of any tilting abnormalities in the limiting ring 42. Compared to existing methods using a level, this method achieves automated and comprehensive levelness detection of the limiting ring 42, eliminating the need for manual operation. This avoids the drawbacks of low efficiency and accuracy issues caused by human factors in manual detection, improving the convenience and timeliness of levelness detection. If any abnormal values ​​are detected during the rotation process, an alarm will sound to alert the user for maintenance. The alarm is existing technology and is not shown in the figure.

[0037] After a period of measurement, the upper laser sensor 31 and the lower laser sensor 32 are prone to tilting due to long-term vibration and loose installation structure, leading to distortion and decreased accuracy of thickness detection data. At this time, the controller drives the second servo motor 62 to rotate the rotating shaft 63 and the connecting frame 64, causing the support ring 71 and the detection plate 78 to rotate synchronously, aligning the horizontal position of the detection plate 78 with the vertical position of the upper laser sensor 31 and the lower laser sensor 32. Then, the controller rotates the detection plate 78 from a 45-degree position to a horizontal position. Finally, the controller directs the lasers emitted by the upper laser sensor 31 and the lower laser sensor 32 to illuminate the target area. The measured values ​​on the top and bottom surfaces of the detection plate 78 are compared with the calibrated values. If the deviation exceeds the normal range, an alarm will be triggered to remind the user to perform maintenance. This allows for timely verification of the installation accuracy and detection accuracy of the upper laser sensor 31 and the lower laser sensor 32. Compared with existing technologies, this technology enables automated online calibration of the upper laser sensor 31 and the lower laser sensor 32 without the need for equipment disassembly or manual calibration and debugging. This eliminates the tedious manual calibration process, reduces equipment downtime losses, and accurately identifies issues such as sensor offset and loose installation, ensuring the accuracy and stability of thickness detection data and meeting the long-term detection needs of continuous industrial production.

[0038] To address the technical problem of difficulty in performing multi-point inspections, which affects the accuracy of thickness measurement, such as... Figure 4 , Figure 10 and Figure 12 As shown, the following preferred technical solutions are provided: like Figure 10 As shown, the pushing assembly 9 includes a push rod 91 fixedly connected to the outer wall of the support ring 71, and a driven rod 92 fixedly connected to the bottom of the rotating plate 43. The push rod 91 and the driven rod 92 are in contact.

[0039] like Figure 12 As shown, the snap-fit ​​assembly 10 includes a second spring 101 fixedly connected to the rotating plate 43, and a snap-fit ​​rod 102 fixedly connected to the other end of the second spring 101. The snap-fit ​​rod 102 is slidably connected to the rotating plate 43. One end of the snap-fit ​​rod 102 is set to an arc shape, and the first snap-fit ​​groove 45 and the second snap-fit ​​groove 46 are also set to an arc shape, which can reduce the frictional resistance when snapping and disengaging, ensuring that the rotating plate 43 rotates smoothly without jamming. At the same time, the snap-fit ​​rod 102 can snap into the first snap-fit ​​groove 45 and the second snap-fit ​​groove 46 respectively, so that the rotating plate 43 can accurately stop at the preset detection position, ensuring the positional accuracy and detection stability of the thickness detection at each point.

[0040] During the SMC sheet thickness detection process, the controller causes the second servo motor 62 to rotate forward, driving the rotating shaft 63 and connecting frame 64 to rotate. This causes the support ring 71 and push rod 91 to rotate synchronously, and the push rod 91 pushes the driven rod 92 to move, causing the rotating plate 43 to rotate within the limiting ring 42. This causes the SMC sheet to be measured in the placement slot 44 to rotate synchronously. During the rotation, the upper laser sensor 31 and the lower laser sensor 32 perform real-time multi-point measurements, which can collect the thickness data of the circumferential points of the SMC sheet, avoiding the random errors of single-point detection. By integrating and calculating multiple sets of data, a precise average thickness value is obtained, reflecting the uniformity of the sheet's circumferential thickness and improving the accuracy and comprehensiveness of a single detection. When the driven rod 92 starts to rotate, the locking rod 102 overcomes the resistance of the second spring 101 and disengages from the first locking slot 45 until the locking rod 102 engages with the second locking slot 46. Subsequently, the upper laser sensor 31 and the lower laser sensor 32... The device 32 pauses detection, and then the first servo motor 22 drives the threaded rod 23 to rotate, causing the threaded block 24 to move the U-shaped mounting plate 25, the upper laser sensor 31, and the lower laser sensor 32 a short distance. Then, the second servo motor 62 rotates in the opposite direction, driving the rotating shaft 63 and the connecting frame 64 to rotate, causing the support ring 71 and the push rod 91 to rotate synchronously until the push rod 91 is in contact with the other side of the driven rod 92 and pushes the driven rod 92 to move in the opposite direction. The rotating plate 43 rotates in the opposite direction within the limiting ring 42, and together with the upper laser sensor 31 and the lower laser sensor 32, real-time multi-point measurement is performed again. This enables dual-dimensional coverage detection of SMC sheet in both radial and circumferential directions, further expanding the detection points, reducing detection blind spots, and collecting multi-area thickness data of the sheet from multiple directions. Compared with the limitations of existing technologies that perform unidirectional and local point detection, this technology can improve the comprehensiveness and accuracy of thickness detection, and adapt to the detection needs of high-quality SMC sheet.
