DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand: the present invention is further explained below in conjunction with specific implementation methods.

[0030] like Figures 1 to 7 As shown, the present invention provides a technical solution: a thickness measuring device suitable for a silicon steel sheet, comprising a workbench 1, a placing truncated table 27 is arranged on the top of the workbench 1, a silicon steel sheet 5 to be measured is placed on the top of the placing truncated table 27, an external fixing component and a mechanical arm component are arranged on the top of the workbench 1, laser rangefinders 4 are arranged on both sides of the silicon steel sheet 5 to be measured, a conveying component is arranged at the bottom of the two laser rangefinders 4, the conveying component is used to drive the two laser rangefinders 4 to move, and detect the thickness of both sides of the silicon steel sheet 5 to be measured, and a transmission component is arranged on one side of the conveying component, and the transmission component is used to drive the placing truncated table 27 to rotate 90 degrees, so that the other two sides of the silicon steel sheet 5 to be measured are respectively facing the detection heads of the two laser rangefinders 4, so that the thickness of the other two sides of the silicon steel sheet 5 to be measured can be detected.

[0031] During operation: In the process of measuring the thickness of silicon steel sheets by the existing device, since the existing silicon steel sheets are four-sided sheets and the thicknesses of the four sides may be different, the laser rangefinder can only measure the thickness of one side of the silicon steel sheet at a time, and then the silicon steel sheet needs to be rotated manually, and the next side is aligned with the laser rangefinder for thickness measurement. The silicon steel sheet is rotated multiple times to measure the thickness of each side, which increases the time and labor costs during the operation, and the position of the rotated silicon steel sheet may shift, which will introduce measurement errors in high-precision thickness measurement. Through the embodiment of the present scheme, in specific use, the silicon steel sheet 5 to be measured is placed directly above the truncated table 27 by the mechanical arm assembly and solidified by the solid assembly, and then the conveying assembly is started to move the two laser rangefinders 4 from the leftmost end to the rightmost end. During the movement, the two laser rangefinders 4 detect the thickness of both sides of the silicon steel sheet 5 to be measured, and after the detection is completed, When the two laser rangefinders 4 continue to move from left to right, one of the laser rangefinders 4 will touch the transmission assembly, causing the silicon steel sheet 5 to be tested to rotate 90 degrees, and its other two sides will respectively face the detection heads of the two laser rangefinders 4. At this time, when the two laser rangefinders 4 move from right to left, the other two sides of the silicon steel sheet 5 to be tested will be detected. Therefore, in the process of the two laser rangefinders 4 moving back and forth through the conveying assembly, the thickness of the four sides of the silicon steel sheet 5 to be tested can be detected. After the detection is completed, the fixed assembly removes the solid of the silicon steel sheet 5 to be tested, and removes the silicon steel sheet 5 to be tested through the mechanical arm assembly and installs the next silicon steel sheet whose thickness needs to be detected. Through the above embodiment, the thickness of the four sides of the silicon steel sheet can be detected. By detecting the thickness of the four sides, the thickness distribution of the entire silicon steel sheet can be more comprehensively understood, and the sides with abnormal thickness can be discovered early to avoid using defective products for production, thereby reducing the scrap rate.

[0032] like Figures 1 to 3 As shown, the conveying assembly includes a plurality of support columns 2, and the plurality of support columns 2 are fixedly mounted on the top of the workbench 1, and the tops of every two support columns 2 are fixedly connected with an open fixing seat 6, and the inner walls of the two open fixing seats 6 are rotatably connected with threaded conveying rods 7, and the outer walls of the two threaded conveying rods 7 are threadedly connected with mounting slides 3, and two laser rangefinders 4 are respectively fixedly mounted above the two mounting slides 3, and the outer walls of the two mounting slides 3 are respectively slidably connected with the inner walls of the two open fixing seats 6, and a driving assembly is provided on one side of the open fixing seat 6, and the driving assembly is used to drive the two threaded conveying rods 7 to rotate.

[0033] During operation: in the initial state, the two mounting slides 3 are located at the leftmost end of the open fixed seat 6. After the silicon steel sheet 5 to be tested is installed by the mechanical arm assembly and the solid assembly, the side surface of the silicon steel sheet 5 to be tested is flush with the detection ports of the two laser rangefinders 4. Then the driving assembly is started, which will drive the two threaded conveying rods 7 to rotate. When the two threaded conveying rods 7 rotate, due to the sliding connection between the mounting slide 3 and the open fixed seat 6, the rotation of the two threaded conveying rods 7 will drive the laser rangefinder 4 to move from the leftmost end to the rightmost end of the open fixed seat 6 through the two mounting slides 3. During the movement, the thickness of both sides of the silicon steel sheet 5 to be tested will be detected. Through the above embodiment, it is achieved that the two laser rangefinders 4 are driven to move to achieve the purpose of thickness detection.

[0034] like Figures 1 to 3 As shown, one end of the two threaded conveying rods 7 is fixedly connected to a transmission ring 8, a transmission belt 9 is transmission-connected between the outer walls of the two transmission rings 8, a driving wheel 10 is transmission-connected to the inner wall at the center of the transmission belt 9, one end of the driving wheel 10 is fixedly connected to a motor 11, and the motor 11 is fixedly installed on the top of the workbench 1.

[0035] During operation: start the motor 11, and its output shaft will drive the driving wheel 10 to rotate. When the driving wheel 10 rotates, it will drive the two driving rings 8 to rotate through the transmission belt 9. When the two driving rings 8 rotate, they will drive the two laser rangefinders 4 through the two mounting slides 3 to move from the leftmost end of the opening fixing seat 6 to the rightmost end, and detect the thickness of two sides of the silicon steel sheet 5 to be tested. When it moves from the rightmost end to the rightmost end and returns to the original position, the other two sides of the silicon steel sheet 5 to be tested are tested.

[0036] like Figure 2 and Figure 7 As shown, the transmission assembly includes two rotating shafts 31, wherein the top of one rotating shaft 31 is fixedly connected to the bottom of the truncated table 27, and the top of the other rotating shaft 31 is fixedly connected to the gear 23, the outer walls of the two rotating shafts 31 are fixedly connected to the transmission ring 24, and the outer walls of the two transmission rings 24 are connected to the transmission belt 25.

[0037] During operation: when the two mounting slides 3 move from the leftmost end of the open fixed seat 6 to the rightmost end, the thickness of the two side surfaces of the silicon steel sheet 5 to be tested will be detected first. When the detection is completed and the movement continues, the gear 23 will be driven to rotate 90 degrees. When the gear 23 rotates 90 degrees, the two transmission rings 24 and the rotating shaft 31 connected to the bottom of the placing table 27 will drive the placing table 27 to rotate 90 degrees. Since the silicon steel sheet 5 to be tested is fixed to the top of the placing table 27 through a fixing assembly, when the placing table 27 rotates 90 degrees, the silicon steel sheet 5 to be tested on the top will be driven to rotate 90 degrees, so that the other two sides of the silicon steel sheet 5 to be tested face the detection head of the laser rangefinder 4, so that when the two mounting slides 3 move from the rightmost end of the open fixed seat 6 to the leftmost end and return to the original position, the other two sides of the silicon steel sheet 5 to be tested can be detected.

[0038] like Figure 2 and Figure 7 As shown, the bottoms of the two rotating shafts 31 are rotatably connected to the base discs 26 , and the bottoms of the two base discs 26 are fixedly installed on the top of the workbench 1 .

[0039] During operation: the position of the rotating shaft 31 is fixed by the two base discs 26 to increase the stability of the transmission assembly.

[0040] like Figures 2 to 5 As shown, a slide rail groove 12 is provided on the inner wall of one side of one of the mounting slides 3, a mounting plate 13 is fixedly connected to one side of one of the mounting slides 3, an inner groove fixing seat 14 is fixedly connected to the inner side of the mounting plate 13, a magnet block 16 is slidably connected to the inner wall of the inner groove fixing seat 14, a rack plate 22 is fixedly connected to one side of the magnet block 16, the teeth of the rack plate 22 are meshed with the teeth of the gear 23, the number of teeth of the rack plate 22 is one fourth of the number of teeth of the rack plate 22, and a magnetic component is provided at the bottom of the magnet block 16, and the magnetic component is used to drive the magnet block 16 to move downward.

[0041] During operation: when the two mounting slides 3 move from the leftmost end of the open fixing seat 6 to the two side surfaces of the silicon steel sheet 5 to be tested for thickness detection, one of the mounting slides 3 will drive the magnet block 16 to move through the mounting plate 13 and the inner groove fixing seat 14 during the movement, and the magnet block 16 will drive the gear 23 to rotate through the rack plate 22 when moving. Since the number of teeth on the rack plate 22 is one-fourth of the number of teeth on the rack plate 22, the effect of driving the silicon steel sheet 5 to be tested to rotate 90 degrees is achieved.

[0042] like Figures 2 to 6As shown, the magnetic assembly includes a reset spring 15, one end of which is fixedly connected to the inner side of the bottom of the inner groove fixing seat 14, and the other end of the reset spring 15 is fixedly connected to the top of the magnet block 16. The inner sides of the inner groove fixing seat 14 are provided with slide rail grooves 18, and both sides of the magnet block 16 are fixedly connected with slide rods 17. The slide rods 17 and the slide rail grooves 18 are slidably connected and adapted to each other. A magnet block 28 is fixedly installed on the top of the workbench 1, and the top surface of the magnet block 28 has opposite magnetism to the bottom surface of the magnet block 16. A positioning assembly is provided on one side of the magnet block 16, and the positioning assembly is used to fix the position of the magnet block 16 after the magnetic assembly drives the magnet block 16 to move downward.

[0043] During operation: after the rack plate 22 is meshed with the gear 23, when the magnet block 16 continues to move from left to right, the magnet block 16 will slowly approach the magnet block 28. Since the magnetism of the surfaces of the magnet block 16 and the magnet block 28 that are close to each other is opposite, the magnet block 16 will be attracted by the magnet block 28 to move downward, and the downward position is limited by the slide bar 17 and the slide rail groove 218. When the magnet block 16 moves downward, the rack plate 22 will also move downward, and at this time the magnet block 16 will touch the positioning component, so that the magnet block 16 that moves downward will not move up and reset after it is separated from the attraction of the magnet block 28. Through the downward movement of the magnet block 16 and the rack plate 22, the rack plate 22 will not mesh with the gear 23 when it moves from right to left, so as to avoid the gear 23 causing the silicon steel sheet 5 to rotate 90 degrees in the opposite direction when it moves from right to left, resulting in the inability to detect the other two sides of the silicon steel sheet 5 to be tested.

[0044] like Figure 3 to Figure 4 As shown, the positioning assembly includes two groups of connecting round blocks 19, and the two groups of connecting round blocks 19 are symmetrically fixed on the outer walls of both sides of the inner groove fixing seat 14. The inner walls of multiple connecting round blocks 19 are provided with socket grooves 20, and the inner walls of one group of socket grooves 20 are all plugged with blocking rods 21, and a pushing assembly is provided on one side of the blocking rod 21, and the pushing assembly is used to push the blocking rod 21.

[0045] During operation: when magnet block 16 is attracted by magnet block 28 and moves downward, when the inner groove fixing seat 14 continues to move, the pushing assembly will push the two blocking rods 21, so that the two blocking rods 21 can also be inserted into the two insertion slots 20 on the other side of the inner groove fixing seat 14. At this time, the top of magnet block 16 after moving downward will be stuck by the blocking rod 21. When the entire rack plate 22 moves from right to left, the rack plate 22 cannot engage with the gear 23. When the entire detection is performed from right to left, the rack plate 22 cannot drive the gear 23 to engage and rotate.

[0046] like Figure 3 to Figure 4As shown, the pushing assembly includes two auxiliary side plates 29, which are respectively installed on the outer walls of the leftmost support column 2 and the rightmost support column 2. A pushing needle rod 30 is fixedly connected to one side of the two auxiliary side plates 29, and the maximum aperture of the pushing needle rod 30 is smaller than the diameter of the blocking rod 21.

[0047] During operation: when the inner groove fixing seat 14 continues to move, the push needle rod 30 on the outer wall of the rightmost support column 2 will squeeze the blocking rod 21, so that when the inner groove fixing seat 14 moves to the rightmost end, the blocking rod 21 is just inserted into the two jack slots 20 on both sides of the inner groove fixing seat 14, blocking the top of the magnet block 16 from moving up and resetting. When the entire rack plate 22 moves from right to left for detection, the rack plate 22 cannot mesh with the gear 23, and the inner groove fixing seat 14 moves to the open position. When the inner groove fixing seat 14 is at the leftmost end, the pushing needle rod 30 on the outer wall of the leftmost supporting column 2 will also squeeze the blocking rod 21, so that the blocking rod 21 is reset. At this time, the top of the magnet block 16 loses its obstruction, and the position of the magnet block 16 is reset through the reset spring 15, so that when the inner groove fixing seat 14 is moved from left to right for detection, the rack plate 22 can mesh with the gear 23. During the entire detection from left to right, the rack plate 22 can drive the gear 23 to mesh and rotate.

[0048] like Figure 1 to Figure 2 As shown, two data receivers 32 are fixedly installed on the top of the workbench 1 , and the two data receivers 32 receive thickness data detected by the two laser rangefinders 4 respectively.

[0049] During operation: the thickness data of the four surfaces detected are received by the data receiver 32, so as to collect data and analyze whether the thickness of the four surfaces is uniform and accurate.

[0050] Working process: First, the silicon steel sheet 5 to be tested is placed directly above the truncated table 27 through the robotic arm assembly and solidified through the solid assembly, the motor 11 is started, and its output shaft drives the driving wheel 10 to rotate. When the driving wheel 10 rotates, it drives the two transmission rings 8 to rotate through the transmission belt 9. When the two transmission rings 8 rotate, they drive the two threaded conveying rods 7 to rotate. When the two threaded conveying rods 7 rotate, due to the sliding connection between the mounting slide 3 and the opening fixed seat 6, the rotation of the two threaded conveying rods 7 will drive the laser rangefinder 4 to move from the leftmost end to the rightmost end of the opening fixed seat 6 through the two mounting slides 3. During the movement, the thickness of both sides of the silicon steel sheet 5 to be tested will be detected.

[0051] Secondly, when the two mounting slides 3 move from the leftmost end of the opening fixing seat 6 to the two sides of the silicon steel sheet 5 to be tested for thickness detection, one of the mounting slides 3 will drive the magnet block 16 to move through the mounting plate 13 and the inner groove fixing seat 14 during the movement. When the magnet block 16 moves, it will drive the gear 23 to rotate through the rack plate 22. Since the number of teeth on the rack plate 22 is one-fourth of the number of teeth on the rack plate 22, it will drive the silicon steel sheet 5 to be tested to rotate 90 degrees. When the gear 23 rotates 90 degrees, it will The two transmission rings 24 and the rotating shaft 31 connected to the bottom of the placing table 27 drive the placing table 27 to rotate 90 degrees. Since the silicon steel sheet 5 to be tested is fixed to the top of the placing table 27 through a fixing assembly, when the placing table 27 rotates 90 degrees, it will drive the silicon steel sheet 5 to be tested on the top to rotate 90 degrees, so that the other two sides of the silicon steel sheet 5 to be tested face the detection head of the laser rangefinder 4, so that when the two mounting slides 3 move from the rightmost end of the opening fixing seat 6 to the leftmost end and return to the original position, the other two sides of the silicon steel sheet 5 to be tested can be detected.

[0052] Then, after the rack plate 22 is meshed with the gear 23, when the magnet block 16 continues to move from left to right, the magnet block 16 will slowly approach the magnet block 28. Since the magnetism of the surfaces of the magnet block 16 and the magnet block 28 that are close to each other is opposite, the magnet block 16 will be attracted by the magnet block 28 to move downward, and the downward position is limited by the slide bar 17 and the slide rail groove 218. When the magnet block 16 moves downward, the rack plate 22 will also move downward, and at this time the magnet block 16 will touch the positioning assembly, so that the magnet block 16 that moves downward will not move up and reset after it is separated from the attraction of the magnet block 28. By moving the magnet block 16 and the rack plate 22 downward, the rack plate 22 will not be in contact with the gear 23 when it moves from right to left. The gear 23 is in meshing relationship to prevent the gear 23 from causing the silicon steel sheet 5 to rotate 90 degrees in the opposite direction when moving from right to left, resulting in the inability to detect the other two sides of the silicon steel sheet 5 to be tested. When the magnet block 16 is attracted by the magnet block 28 and moves downward, when the inner groove fixing seat 14 continues to move, the pushing assembly will push the two blocking rods 21, so that the two blocking rods 21 can also be inserted into the two jack slots 20 on the other side of the inner groove fixing seat 14. At this time, the top of the magnet block 16 after moving downward will be stuck by the blocking rod 21. When the entire rack plate 22 moves from right to left, the rack plate 22 cannot be meshed with the gear 23. When the entire detection is performed from right to left, the rack plate 22 cannot drive the gear 23 to mesh and rotate.

[0053] Finally, the thickness data of the four surfaces detected are received by the data receiver 32, so as to collect data and analyze whether the thickness of the four surfaces is uniform and accurate.
