Description

Technical Field

[0001] This invention relates to the field of printing and packaging inspection technology, specifically to a sensor for detecting the thickness of hot stamping on hot stamping products. Background Technology

[0002] Hot stamping is a common surface treatment method in the printing and packaging industry, widely used in the processing of trademarks, packaging boxes, decorative patterns and high-end book covers. Hot stamping can not only enhance the visual effect and grade of products, but also increase the surface wear resistance and anti-counterfeiting function to a certain extent. However, in actual production, the thickness control of hot stamping is a critical process parameter. If the hot stamping thickness is insufficient, it is easy to cause the surface color to be dull and the gloss to be poor, and even fade or peel off during use or transportation. If the hot stamping thickness is too large, it will cause waste of metal foil material and may lead to uneven surface, affecting the stability of subsequent processes such as lamination, creasing, and die-cutting, ultimately affecting product quality and production costs.

[0003] Traditional hot stamping thickness testing methods have certain errors, especially in industrial production. Accurate hot stamping layer thickness is crucial for product quality and production efficiency. Most current testing equipment has problems such as insufficient adaptability and complex operation, which cannot efficiently and accurately measure the geometric thickness of the hot stamping layer. This affects the stability of the overall production process and product quality. At the same time, when the hot stamping area is too large, air can easily be trapped between the hot stamping layer and the substrate, resulting in air bulging.

[0004] Currently, there are two main types of methods for detecting the thickness of hot stamping in the industry: one is manual inspection, which usually involves visual inspection or sampling and measuring the hot stamping layer with simple tools such as vernier calipers and micrometers. This method has limited accuracy and the results are easily affected by the operator's experience and subjective judgment, making it difficult to achieve continuous and rapid online inspection. The other type is electronic sensor inspection, which uses laser displacement sensors, optical inspection instruments, etc. to scan and measure the thickness of the hot stamping layer. Although electronic sensors can provide high accuracy, the equipment cost is high and the installation environment and maintenance conditions are demanding, which is not conducive to large-scale promotion and use on the production line.

[0005] Therefore, there is a need for a hot stamping thickness detection sensor that is structurally sound, reliable in detection, adaptable to different thickness ranges, and has intuitive signal prompts, in order to solve the problems of low efficiency, poor accuracy, insufficient adaptability, and cumbersome operation of existing detection methods, thereby improving the stability and production efficiency of the hot stamping process.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1.

[0043] 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.

[0044] Example 1: Please refer to Figures 1-5 A hot stamping product printing thickness detection sensor includes a grip component 1, which includes a grip handle 11. Specifically, the grip handle 11 has an ergonomically designed groove for easy gripping by workers. An adjustment component 2 is rotatably connected to the front end of the grip handle 11. An installation component 3 is fixedly connected to the end of the adjustment component 2 away from the grip handle 11. The installation component 3 includes an installation cylinder 31. A set of sensing components 4 is slidably connected to the inner wall of the installation cylinder 31 near the rear end. A set of detection components 5 is slidably connected to the inner wall of the installation cylinder 31 near the front end. The sensing components 4 and the detection components 5 are used for precise size control and geometric thickness detection.

[0045] Please see Figure 2 , Figure 3A positioning gear 12 is rotatably connected to the front end of the grip 11. Specifically, a mounting arm 111 is welded and fixed to the front end of the grip 11. The positioning gear 12 is rotatably connected to the end of the mounting arm 111. A rotating hole is provided at the end of the mounting arm 111. A bearing is sandwiched between the outer wall of the rotating shaft of the positioning gear 12 and the inner wall of the rotating hole. The bearing can reduce the friction generated when the positioning gear 12 rotates, thereby reducing device wear. A mounting shell 13 is sleeved on the outside of the positioning gear 12. The mounting shell 13 is used to prevent debris from sticking to the positioning gear 12. A sliding groove 112 is provided on the side wall of the grip 11. A sliding tooth block 14 is slidably connected to the inner wall of the sliding groove 112. The sliding tooth block 14 meshes with the positioning gear 12. A sliding rod 15 is fixedly installed on the rear end face of the sliding tooth block 14. A spring 16 is sleeved on the outer wall of the sliding rod 15. Specifically, a pull ring is fixedly connected to the rear end of the sliding rod 15 after passing through the rear side wall of the sliding groove 112. The front end of the spring 16 abuts against the rear end face of the sliding tooth block 14, and the rear end of the spring 16 abuts against the rear side wall of the sliding groove 112. The sliding tooth block 14 engages with the positioning gear 12, preventing the positioning gear 12 from rotating at the end of the mounting arm 111. By pulling the pull ring, the spring 16 is compressed, causing the sliding tooth block 14 to move backward in the sliding groove 112, disengaging the sliding tooth block 14 from the positioning gear 12 and allowing the positioning gear 12 to resume free rotation at the end of the mounting arm 111.

[0046] Please see Figures 2-5 The adjusting assembly 2 includes a connecting arm 21, which is coaxially and fixedly connected to the positioning gear 12. Specifically, the connecting arm 21 has a connecting hole on its rear side wall, and a groove on the inner wall of the connecting hole. The outer wall of the rotating shaft of the positioning gear 12 has a protrusion, the size of which matches the size of the inner wall of the groove. The protrusion limits the groove, allowing the connecting arm 21 to rotate synchronously with the positioning gear 12. A mounting bracket 211 is fixedly installed at the front end of the connecting arm 21. A rotating chamber 22 is rotatably connected inside the mounting bracket 211. The front end face of the rotating chamber 22 has several storage compartments equidistantly spaced around its circumference. The inner walls of the storage cylinders 221 are all fixedly installed with fixed magnets 23. Specifically, the distance between the fixed magnets 23 and the front end face of the rotating chamber 22 increases gradually inside the storage cylinders 221. An adjusting turntable 24 is coaxially fixedly installed at the center of the front end face of the rotating chamber 22. Specifically, the front end face of the adjusting turntable 24 has a number of positioning grooves that are equal in number to the number of fixed magnets 23. The depth of the positioning grooves is greater than or equal to the maximum depth of the fixed magnets 23 from the front end face of the rotating chamber 22 in the storage cylinders 221. The inner walls of the positioning grooves are all arc-shaped.

[0047] Example 2: Please refer to Figure 2 , Figures 4-9 , Figure 13 , Figure 14A hot stamping thickness detection sensor for hot stamping products differs from Embodiment 1 in that the rear end of the mounting cylinder 31 is fixedly connected to the front end of the mounting frame 211. Specifically, an extension plate 311 is welded and fixed to the outer wall of the rear end of the mounting cylinder 31, and a connecting rod 32 is threadedly fixed to the extension plate 311. The end of the connecting rod 32 away from the mounting cylinder 31 is threadedly fixedly connected to the front end of the mounting frame 211. Three indicator lights 33 are equidistantly mounted on the outer wall of the mounting cylinder 31. Specifically, a mounting platform 312 is mounted on the outer wall of the mounting cylinder 31, and the three indicator lights 33 are equidistantly mounted on the end face of the mounting platform 312. The indicator lights 33 are LED lights, and the light colors are white, green and red respectively. The wiring terminals of the three indicator lights 33 pass through the side wall of the mounting cylinder 31 and extend into the interior of the mounting cylinder 31. Four extension arms 313 are fixedly installed on the outer wall of the front end of the mounting cylinder 31. The ends of the four extension arms 313 are rotatably connected to positioning wheels 34. Specifically, the four extension arms 313 are welded and fixed to the outer wall of the mounting cylinder 31. The positioning wheels 34 are used to abut against the surface of the material to be tested. An equal number of first rotating shafts 314 and second rotating shafts 315 are installed equidistantly on the circumference of the outer wall of the mounting cylinder 31.

[0048] Please see Figure 2 , Figures 4-9 , Figure 13 , Figure 14 The sensing component 4 includes a fixed piston 41. Two fixed rods 411 are fixedly mounted on the rear end face of the fixed piston 41. A mounting plate 412 is fixedly mounted on the ends of the two fixed rods 411 away from the fixed piston 41. A positioning protrusion 413 is fixedly mounted on the rear end face of the mounting plate 412. The positioning protrusion 413 engages with the adjusting turntable 24. Specifically, the rear end face of the positioning protrusion 413 is rounded. A support rod 414 is fixedly mounted on the rear end face of the fixed piston 41. A movable magnet 42 is fixedly mounted on the rear end of the support rod 414. The movable magnet 42 is slidably inserted into the inner wall of the storage cylinder 221. The movable magnet 42 magnetically attracts one of the fixed magnets 23. For details, please refer to [link / reference]. Figure 7 , Figure 8 , Figure 14The outer diameter of the movable magnet 42 is smaller than the inner diameter of the storage cylinder 221, leaving room for movement. A guide plate 316 is welded and fixed to the inner wall of the rear end of the mounting cylinder 31. Two sliding holes are opened on the rear end face of the guide plate 316. The rear ends of the two fixed rods 411 pass through the sliding holes and are welded and fixed to the mounting plate 412. The sliding holes have a limiting and guiding effect on the fixed rods 411, so that the fixed piston 41 can only slide back and forth inside the mounting cylinder 31 and cannot rotate inside the mounting cylinder 31. The outer wall size of the positioning protrusion 413 is adapted to the inner wall size of the positioning groove of the adjusting turntable 24. By manually twisting the rotating chamber 22, the adjusting turntable 24 is rotated, and the positioning protrusion 413 is pushed out from one of the positioning grooves of the adjusting turntable 24. The positioning protrusion 413 drives the fixed piston 41 to move forward through the fixed rod 411, causing the movable magnet 42 to separate from the fixed magnet 23 and slide the movable magnet 42 out of the storage cylinder 221. When the positioning protrusion 413 comes to the front of another positioning groove of the adjusting turntable 24, the movable magnet 42 also comes to the front of another storage cylinder 221. At this time, the fixed magnet 23 inside the storage cylinder 221 attracts the movable magnet 42 through magnetic force. The movable magnet 42 drives the fixed piston 41 to move backward inside the mounting cylinder 31 through the support rod 414. Since the distance between the fixed magnet 23 and the front end face of the rotating chamber 22 increases step by step inside the storage cylinder 221, the position of the fixed piston 41 inside the mounting cylinder 31 is adjusted.

[0049] Please see Figure 2 , Figures 4-9 , Figure 13 , Figure 14 A sensing cylinder 43 is fixedly installed at the center of the rear end face of the fixed piston 41. A piston rod 44 is slidably connected inside the sensing cylinder 43. Specifically, the inner diameter of the sensing cylinder 43 is less than or equal to one-tenth of the diameter of the fixed piston 41, thereby amplifying the water level change characteristics inside the sensing cylinder 43. A through-hole is opened at the center of the front end face of the fixed piston 41, which communicates with the inside of the sensing cylinder 43. An arc-connecting plate 441 is fixedly installed after the rear end of the piston rod 44 passes through the rear end wall of the sensing cylinder 43. The rear end face of the fixed piston 41 is fixed. A support plate is installed, and three conductive plates 45 are equidistantly installed on the top surface of the support plate. The three conductive plates 45 are electrically connected to three indicator lights 33 through wires. Specifically, a grounding block is fixedly installed on the bottom surface of the arc-connecting plate 441. The grounding block is connected to an external power source through wires. The grounding block and the conductive plate 45 are made of copper, which has good conductivity and corrosion resistance. The position of the arc-connecting plate 441 is adjusted according to the position of the piston in the piston rod 44 inside the induction cylinder 43, thereby indirectly controlling the opening and closing of the three indicator lights 33.

[0050] Example 3: Please refer to Figures 2 to 16A hot stamping thickness detection sensor for hot stamping products differs from Embodiment 1 in that the detection component 5 includes a detection piston 51 and several sets of displacement amplification components 53. The detection piston 51 is slidably connected to the front end of the inner wall of the mounting cylinder 31. A rotating frame 511 is fixedly installed at the front end of the detection piston 51, and a detection wheel 52 is rotatably connected to the end of the rotating frame 511. Specifically, the rotating frame 511 is welded and fixed to the front end face of the detection piston 51. A rotating hole is opened at the end of the rotating frame 511. A bearing is sandwiched between the outer wall of the rotating shaft of the detection wheel 52 and the inner wall of the rotating hole. The bearing can reduce the friction generated when the detection wheel 52 rotates, reduce device wear, and under normal conditions... The maximum outer diameter of the detection wheel 52 is equal to the maximum outer diameter of the positioning wheel 34. The displacement amplification assembly 53 includes a first drive rod 531, which is rotatably connected to a first rotating shaft 314. Torsion springs 533 are installed between several first drive rods 531 and several first rotating shafts 314. An abutment wheel 532 is rotatably connected to the end of the first drive rod 531. The outer wall of the abutment wheel 532 slides against the rear end face of the detection piston 51. A connecting rod 534 is hinged to the other end of the first drive rod 531. Specifically, a rotating hole that passes through the left and right sides is opened on the side wall of the first drive rod 531. The rotating hole is rotatably connected to the first rotating shaft 314. According to the position of the rotating hole... The first drive rod 531 is divided into a short rod and a long rod, the length of which is greater than or equal to five times that of the short rod. The short rod is located inside the mounting cylinder 31. The torsion spring 533 exerts a torsional force on the first drive rod 531, causing the abutment wheel 532 to abut tightly against the rear end face of the detection piston 51. The end of the connecting rod 534 away from the first drive rod 531 is hinged to a second drive rod 535, which is rotatably connected to the second rotating shaft 315. The end of the second drive rod 535 away from the connecting rod 534 is slidably connected to a drive piston 54, which is slidably connected to the inner wall of the mounting cylinder 31. Specifically, the side wall of the second drive rod 535 has a through-hole opening. A rotating hole is rotatably connected to the second rotating shaft 315. The second drive rod 535 is divided into a short rod and a long rod according to the position of the rotating hole. The length of the long rod is greater than or equal to five times that of the short rod. The long rod is located inside the mounting cylinder 31. A sliding block 536 is hinged to the end of the long rod. Several slide rails 541 are welded and fixed at equal intervals around the front end face of the drive piston 54. The inner wall size of the slide rail 541 is adapted to the size of the sliding block 536. The sliding block 536 is slidably connected to the inner wall of the slide rail 541. The second drive rod 535 drives the drive piston 54 to move back and forth on the inner wall of the mounting cylinder 31 through the sliding block 536. Silicone oil is filled between the drive piston 54 and the fixed piston 41.

[0051] By manually twisting the rotating chamber 22, the adjusting turntable 24 is rotated, pushing the positioning protrusion 413 out of one of the positioning slots of the adjusting turntable 24. The positioning protrusion 413 drives the fixed piston 41 forward through the fixed rod 411, causing the movable magnet 42 to separate from the fixed magnet 23 and slide out of the storage cylinder 221. When the positioning protrusion 413 comes to the front of the other positioning slot of the adjusting turntable 24, the movable magnet 42 also comes to the front of the other storage cylinder 221. At this time, the fixed magnet 23 inside the storage cylinder 221 is attracted to the movable magnet 42 by magnetic force. The support rod 414 drives the fixed piston 41 to move backward inside the mounting cylinder 31. Since the distance between the fixed magnets 23 and the front end of the rotating chamber 22 increases progressively inside the storage cylinder 221, the distance between the driving piston 54 and the fixed piston 41 is adjusted to accommodate the detection of hot stamping products of different thicknesses. The operator holds the handle 11 to make the positioning wheel 34 roll on the surface of the object to be tested. When the positioning wheel 34 does not detect the hot stamping thickness, the detection piston 51 does not move, the displacement amplification component 53 does not work, and the silicone oil filling the space between the driving piston 54 and the fixed piston 41 is not activated. When the piston rod 44 is pushed, it cannot move the arc-connecting plate 441. At this time, the contact block of the arc-connecting plate 441 abuts against the first conductive plate 45, and the white indicator light 33 illuminates. When the positioning wheel 34 detects the normal hot stamping thickness, the detection piston 51 moves slightly. The slight displacement of the detection piston 51 is amplified by the displacement amplification component 53 and then amplified by the induction cylinder 43 to reflect the internal water level change, pushing the piston rod 44 to move. The piston rod 44 then moves the arc-connecting plate 441, at which point the contact block of the arc-connecting plate 441 abuts against the second conductive plate 45. At this time, the green indicator light 33 lights up; when the hot stamping area is too large, air is easily trapped between the hot stamping layer and the substrate, resulting in air bulges. When the positioning wheel 34 detects the air bulges, the air bulges lift the positioning wheel 34. At this time, the detection piston 51 moves significantly. The slight displacement of the detection piston 51 is amplified by the displacement amplification component 53 and then amplified by the induction tube 43 to amplify the characteristics of the internal water level change, pushing the piston rod 44 to move. The piston rod 44 drives the arc receiving plate 441 to move. At this time, the arc receiving block of the arc receiving plate 441 abuts against the third conductive plate 45. At this time, the red indicator light 33 lights up.

[0052] The working principle of this invention is as follows: When the operator holds the handle 11 for testing, the angular position is locked by the engagement of the positioning gear 12 at the front end of the handle 11 with the sliding tooth block 14. Pulling the pull ring causes the sliding tooth block 14 to disengage from the positioning gear 12, thereby allowing the positioning gear 12 to resume free rotation at the end of the mounting arm 111. The positioning gear 12 is coaxially and fixedly connected to the connecting arm 21. The positioning gear 12 drives the mounting cylinder 31 to rotate synchronously through the connecting arm 21, thereby adjusting the grip angle according to the actual situation.

[0053] Before the testing begins, the operator rotates the rotating chamber 22 to rotate the adjusting turntable 24, pushing the positioning protrusion 413 out of one of the positioning slots of the adjusting turntable 24. The positioning protrusion 413 drives the fixed piston 41 forward through the fixed rod 411, causing the movable magnet 42 to separate from the fixed magnet 23 and slide the movable magnet 42 out of the storage cylinder 221. When the positioning protrusion 413 comes to the front of the other positioning slot of the adjusting turntable 24, the movable magnet 42 also comes to the front of the other storage cylinder 221. At this time, the fixed magnet 23 inside the storage cylinder 221 is attracted to the movable magnet 42 by magnetic force. The movable magnet 42 drives the fixed piston 41 to move backward inside the mounting cylinder 31 through the support rod 414. Since the distance between the fixed magnet 23 and the front end of the rotating chamber 22 increases step by step inside the storage cylinder 221, the position of the fixed piston 41 inside the mounting cylinder 31 is adjusted to adjust the sensitivity of the sensing component 4, so that the sensing component 4 can clearly sense the hot stamping thickness and achieve accurate detection.

[0054] A sensor cylinder 43 is installed at the rear end of the fixed piston 41. A piston rod 44 is slidably connected inside the sensor cylinder 43. An arc plate 441 is fixedly connected to the rear end of the piston rod 44. The arc plate 441 can form different contact states with the three conductive plates 45 set on the support plate, thereby controlling the on / off state of the three indicator lights 33 on the outer wall of the mounting cylinder 31. The light colors of the three indicator lights 33 are white, green and red, respectively. Silicone oil is filled between the fixed piston 41 and the driving piston 54. The silicone oil can transmit pressure to the piston rod 44 and cause the piston rod 44 to move.

[0055] During the testing process, the four positioning wheels 34 at the front end of the mounting cylinder 31 are first brought into contact with the surface of the material to be tested. The testing piston 51 contacts the surface of the material to be tested through the testing wheels 52. When the hot stamping thickness contacted by the testing wheels 52 is zero or does not reach the preset thickness, the testing piston 51 does not move, the displacement amplification component 53 does not work, the driving piston 54 does not work, the piston rod 44 remains in the initial position, the contact block of the arc plate 441 contacts the first conductive plate 45, and the white indicator light 33 illuminates. If the testing wheels 52 contact the hot stamping layer of normal thickness, the testing piston 51 will move slightly. This displacement is amplified step by step through the first driving rod 531, connecting rod 534, and second driving rod 535 of the displacement amplification component 53 and then transmitted to the driving piston 54. The torsion spring 533 is compressed, and the driving piston 54 pushes the silicone oil to press against the fixed piston 41, thereby pushing the piston rod 44 to move backward, causing the arc plate 441 to move backward. When the device contacts the second conductive plate 45, the green indicator light 33 illuminates. When the positioning wheel 34 detects an air bulge, the air bulge lifts the positioning wheel 34, causing the detection piston 51 to displace significantly. This displacement is amplified by the displacement amplification component 53, resulting in an even greater displacement of the drive piston 54. This pushes the piston rod 44 to move further, causing the arc plate 441 to contact the third conductive plate 45. The red indicator light 33 then illuminates, alerting the operator. When the device stops detecting, the torsion spring 533 releases its elastic force. The first drive rod 531 pushes the detection piston 51 back to its original position via the abutment wheel 532. The second drive rod 535 drives the drive piston 54 back to its original position via the sliding block 536. The drive piston 54 draws out the silicone oil from the sensing cylinder 43 under negative pressure. Under the action of negative pressure, the piston rod 44 drives the arc plate 441 back to its original position, illuminating the white indicator light 33, facilitating the next detection operation. At this point, the device has completed its operation.
