Abstract
Description
Technical Field
[0001] This invention relates to the field of electronic seal measurement technology, and in particular to a seal thickness measuring device. Background Technology
[0002] Electronic seals are core components used in fields such as power, communications, and logistics for anti-counterfeiting, anti-theft, and prevention of unauthorized opening. The thickness and dimensional accuracy of electronic seals directly affect the assembly sealing performance, locking reliability, and service life of the seals. Therefore, high-precision thickness testing is required for electronic seals before they leave the factory.
[0003] Current methods for measuring the thickness of electronic seals mostly involve manual handheld caliper measurement or single-point laser detection. Manual measurement requires manually aligning the workpiece and wiping away surface dust, which is cumbersome and inefficient. In addition, manual clamping and positioning are prone to errors, resulting in large fluctuations in measurement data. Although single-point laser detection eliminates the need for manual contact, the surface of electronic seals is prone to adhering to dust and particulate impurities left over from the production process. Direct measurement can lead to inflated thickness values. Furthermore, single-point detection cannot cover the overall thickness distribution of the workpiece, easily missing defective products with uneven thickness, making it difficult to guarantee detection accuracy.
[0004] Some improvement plans attempt to add a simple cleaning structure, but the wiping, positioning, and measurement processes need to be completed manually. The disconnect between these processes leads to low testing efficiency and cannot meet the needs of mass production.
[0005] Therefore, a seal thickness measuring device needs to be designed to solve the above problems. Summary of the Invention

The arc-shaped guide groove trajectory drives the cleaning brush bristles to sweep vertically back and forth.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood through the specific circumstances.
[0042] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0043] First Embodiment
[0044] See Figures 1-8 In a first embodiment of the present invention, a seal thickness measuring device includes:
[0045] Base 1, on which a positioning and cleaning mechanism 2 and a laser thickness measuring mechanism 3 are provided;
[0046] The positioning and cleaning mechanism 2 includes a stand 201, a vertical plate 202, an electric telescopic rod 203, a support seat 204, a main frame 205, a sliding plate 206, a cleaning box 207, a piston 208, a guide seat 209, a positioning clamping block 210, an inflation tube 220, and an elastic airbag.
[0047] The upright 201 is fixedly installed on the base 1, the vertical plate 202 is fixedly installed on the top of the base 1, the electric telescopic rod 203 is fixedly installed on the vertical plate 202, the telescopic end of the electric telescopic rod 203 is fixedly connected to the bearing seat 204, the main frame 205 is fixedly installed on the top of the bearing seat 204, the slide plate 206 is vertically slidably installed on the main frame 205, the cleaning box 207 is fixedly installed on the top of the slide plate 206, the piston 208 is slidably sealed on the inflation tube 220, the inflation tube 220 is integrally formed with the elastic airbag, the elastic airbag is fixedly connected to the positioning clamping block 210, and the guide seat 209 is fixedly installed on the side of the upright 201.
[0048] It should be added that the side of the positioning clamping block 210 is set with a wear-resistant rubber pad to ensure the stability of the clamping, increase the clamping friction to prevent the workpiece from slipping, and can flexibly fit the electronic seal surface to avoid indentation and scratches caused by rigid clamping, thus protecting the integrity of the workpiece's appearance.
[0049] It should also be noted that both the electric telescopic rod 203 and the electric telescopic rod 304 are connected to an external PLC controller. The program is set in advance on the external PLC controller, which can accurately control the movement stroke of the electric telescopic rod 203 and the electric telescopic rod 304.
[0050] Furthermore, the positioning and cleaning mechanism 2 also includes an inner support 211, a movable component 212, a hollow component 213, cleaning bristles 214, a suction hole 215, a suction pipe 216, a traction rod 217, an arc-shaped guide groove 218, a straight groove 219, a stabilizing component 221, and a connecting groove 222. The inner support 211 is fixedly installed on the side wall of the cleaning box 207, and the movable component 212 is vertically slidably installed on the inner support 211. The movable component 212 is fixedly connected to the suction pipe 216, and the suction pipe 216 is fixedly connected to the hollow component 213. It should be noted that the suction pipe 216 is connected to an external vacuum cleaner via a suction hose. Neither the external vacuum cleaner nor the suction hose is shown in the attached diagram. This is a conventional technical solution and will not be described in detail here. It is used for vacuuming. The external vacuum cleaner forms a negative pressure air duct through the suction hose, suction pipe 216 and suction hole 215. The dust particles swept off by the cleaning brush bristles 214 are immediately sucked away by the negative pressure, preventing the dust from falling and adhering to the electronic seal surface again. This ensures the cleanliness of the surface to be tested from the source and reduces the error in thickness measurement.
[0051] The cleaning brush bristles 214 are fixedly mounted on the hollow part 213, the dust suction hole 215 is opened on the hollow part 213, the traction rod 217 is fixedly mounted on the dust suction pipe 216, the side of the stand 201 has an arc-shaped guide groove 218 and a straight groove 219, the arc-shaped guide groove 218 and the straight groove 219 are connected, the traction rod 217 is located in the arc-shaped guide groove 218, the stabilizer 221 is fixedly mounted on the top of the cleaning box 207, the side of the stand 201 has a connecting groove 222, the stabilizer 221 is slidably mounted in the connecting groove 222. It should be noted that the stabilizer 221 slides and limits itself along the connecting groove 222, and uses its own counterweight and the constraint of the groove to limit the offset and shaking of the cleaning box 207 during operation, and ensure the verticality and stability of the overall transfer, cleaning and resetting process.
[0052] It should be added that the cleaning brush bristles 214 are made of antistatic modified PA66 nylon filament material, which has the characteristics of antistatic and dust-free, high wear resistance, flexibility and non-deformation. During the reciprocating cleaning process, it does not adsorb micro dust impurities or shed or flatten the bristles. It can thoroughly clean the floating dust on the surface of electronic seals without scratching the surface of the workpiece. It is wear-resistant and durable with long-term use and has a stable cleaning effect.
[0053] The elastic airbag is made of natural latex or neoprene rubber, which is highly elastic, airtight, wear-resistant and anti-aging, and dust-free. It can also hold the sealed workpiece flexibly without damaging it.
[0054] Furthermore, a square groove is provided on the side of the cleaning box 207, the elastic airbag is fixedly installed in the square groove, the inflation tube 220 is fixedly installed on the cleaning box 207, and the positioning clamping block 210 is slidably installed in the square groove. It should be noted that the elastic airbag is located inside the square groove, which is not shown in the figure.
[0055] Furthermore, a first ball is movably mounted on the end of the piston component 208, and the first ball is rolled on the guide seat 209. A second ball is movably mounted on the end of the traction rod 217, and the second ball is rolled on the inner wall of the arc-shaped guide groove 218. It should be noted that this facilitates the movement of the piston component 208 and the traction rod 217. The first ball is mounted on the end of the piston component 208, and the second ball is mounted on the end of the traction rod 217. Rolling friction is used instead of sliding friction, which effectively reduces motion resistance, reduces component wear and jamming, and ensures that the piston component and the traction rod move smoothly and stably along the groove and the inclined surface, thereby improving the reliability and service life of the mechanism.
[0056] Furthermore, a guide is fixedly installed on the piston 208, and the guide is slidably installed on the cleaning box 207. A translation seat is fixedly installed on both sides of the bearing seat 204. A translation groove is opened on the side of the upright 201, and the translation seat is slidably installed in the translation groove. The bottom of the bearing seat 204 is in contact with the base 1. It should be noted that this allows the bearing seat 204 to move stably.
[0057] In this embodiment:
[0058] The electronic seal is placed on top of the carrier 204. The traction rod 217 is initially in the straight groove 219. The ball bearing 1 on the piston 208 is initially in contact with the side of the stand 201. The electric telescopic rod 203 is activated, which moves the carrier 204. The carrier 204 moves the electronic seal. When the carrier 204 moves, the main frame 205, slide plate 206, cleaning box 207, piston 208, and traction rod 217 move synchronously. The ball bearing 1 on the piston 208 pushes the piston 208 to move through the inclined surface of the guide seat 209. This allows the piston 208 to move within the inflation tube 220, inflating the elastic airbag. The expansion of the elastic airbag moves the positioning clamping block 210, thereby... The positioning clamping blocks 210 on both sides can clamp and fix the electronic seal. When the ball on the piston 208 separates from the inclined surface on the guide seat 209, the traction rod 217 enters the arc-shaped guide groove 218 through the straight groove 219. Under the guidance of the arc-shaped guide groove 218, the traction rod 217 will move vertically during the movement, which will cause the suction pipe 216, the moving part 212, the hollow part 213 and the cleaning brush 214 to move vertically back and forth. The cleaning brush 214 cleans the dust on both sides of the electronic seal, and the suction hole 215 adsorbs the cleaned dust. In this way, the electronic seal can be automatically clamped and cleaned during the movement of the electronic seal, which is convenient for subsequent laser thickness measurement.
[0059] It should be added that this invention is for measuring the thickness of electronic seals of the same specification, meaning that the specifications of the electronic seals are fixed and it is not applicable to electronic seals of different specifications.
[0060] Second Embodiment
[0061] The second embodiment of the present invention will be further described below with reference to the accompanying drawings and embodiments.
[0062] Please refer to the following: Figures 8-10In this embodiment, a seal thickness measuring device includes a laser thickness measuring mechanism 3 comprising a second connecting groove 301, a third connecting groove 302, a fourth connecting groove 303, a second electric telescopic rod 304, a support push block 305, an integral part 306, a T-shaped part 307, a force-bearing part 308, a laser rangefinder 309, and a force-applying part 310. The side of the stand 201 is provided with the second connecting groove 301, the third connecting groove 302, and the fourth connecting groove 303. The second connecting groove 301 connects with the first connecting groove 222, the straight groove 219, and the third connecting groove 303. 02 is connected to the connecting groove 4 303. The electric telescopic rod 2 304 is fixedly installed on the bottom inner wall of the connecting groove 2 301. The telescopic end of the electric telescopic rod 2 304 is fixedly connected to the support push block 305. The integral part 306 is fixedly installed on the stand 201. The T-shaped part 307 is vertically slidably installed on the integral part 306. The force-bearing part 308 is fixedly installed on the bottom of the T-shaped part 307. The laser rangefinder 309 is fixedly installed on the T-shaped part 307. The force-applying part 310 is fixedly installed on the top of the stabilizing part 221.
[0063] It should be added that the top of the force-applying component 310 is movably equipped with a ball bearing 3, and the bottom of the force-receiving component 308 is set with multiple inclined force-receiving surfaces. The ball bearing 3 on the top of the force-applying component 310 squeezes the force-receiving component 308, causing the force-receiving component 308 to slowly reciprocate vertically. In addition, the T-shaped component 307 is made of steel and has a relatively heavy weight, which can ensure the stability of the whole movement. The T-shaped component 307 and the integrated component 306 slide vertically together, with good limiting and guiding performance, ensuring that the laser rangefinder 309 only moves smoothly up and down in the vertical direction without horizontal deviation, ensuring that the thickness measuring optical path is perpendicular to the electronic seal surface and avoiding measurement errors caused by misalignment.
[0064] Furthermore, the multi-section interconnected slots and smooth trajectory transitions enable orderly switching of component workstations and precise positioning and avoidance, providing reliable mechanical trajectory constraints for each process, including clamping, cleaning, thickness measurement, and resetting. Two sets of laser rangefinders 309 are installed on both the left and right sides of the device, with three units evenly distributed along the electronic seal transfer direction in each set. The two sets of laser rangefinders 309 are arranged symmetrically facing each other. By measuring the difference between the distance between the left and right optical paths and the optical path blocked by the electronic seal, the actual thickness of the electronic seal is accurately calculated. The two sets of laser rangefinders form a multi-point array, which can simultaneously cover different areas in the width and transfer directions of the electronic seal, achieving full-area multi-point synchronous thickness measurement. This completely avoids the problem of missed detection of defects such as uneven thickness and edge deviation, further improving the comprehensiveness, consistency, and accuracy of thickness measurement.
[0065] In this embodiment:
[0066] During the movement of the cleaning box 207, the stabilizer 221 moves, causing it to enter the area where the first connecting groove 222 and the second connecting groove 301 are connected. The traction rod 217 moves to the area where the straight groove 219 is connected to the second connecting groove 301. At this point, the cleaning clamping work is completed, that is, the first ball on the piston 208 separates from the guide seat 209, the elastic airbag returns to its original state, and the positioning clamping block 210 releases its clamping on the electronic seal. At this time, the electric telescopic rod 203 stops working, and the traction rod 217 contacts the support push block 305. Then, the electric telescopic rod 304 is activated, causing the support push block 305 to move downward. At this time, due to the gravity of the cleaning box 207, the traction rod 217, and the stabilizer 221, the support push block 305 moves downward until the stabilizer 221 moves to the area where the second connecting groove 301 and the third connecting groove 302 are connected. The traction rod 217... The device moves to the area where connecting slot 201 and connecting slot 4 303 are connected. During this process, cleaning box 207 moves slide plate 206, causing slide plate 206 to move into main frame 205. Electric telescopic rod 204 stops working, while electric telescopic rod 1 203 continues working, causing stabilizer 221 to move into connecting slot 302 and traction rod 217 to move into connecting slot 4 303. The force-applying component 310 on stabilizer 221 will squeeze force-receiving component 308. During the slow movement of stabilizer 221, the force-receiving component 308 is squeezed first, causing T-shaped component 307, force-receiving component 308 and laser rangefinder 309 to move upward as a whole. Then, due to the gravity of T-shaped component 307, force-receiving component 308 and laser rangefinder 309, they move downward as a whole. This allows laser rangefinder 309 to perform thickness measurement on a large area of the area after electronic seal cleaning, with high measurement accuracy.
[0067] After the measurement is completed, the electronic seal is removed from the carrier 204. First, the electric telescopic rod 203 moves the carrier 204 back a certain distance, so that the traction rod 217 moves to the support push block 305. At this time, a new electronic seal to be measured is placed on the carrier 204. Then, the electric telescopic rod 304 is started to lift the support push block 305, so that the stabilizer 221 moves into the connecting groove 222 and the traction rod 217 moves into the straight groove 219. Then, the electric telescopic rod 203 is started again. At this time, the carrier 204 performs cleaning, positioning and clamping treatment on the electronic seal when it moves back. After cleaning, positioning and clamping treatment, the laser rangefinder 309 in front performs large-scale thickness measurement treatment on the cleaned area of the electronic seal.
[0068] This device automatically completes the entire process of electronic seal transfer, adaptive clamping, surface negative pressure dust removal, avoidance alignment, multi-point laser scanning thickness measurement, and automatic reset cyclic feeding through the trajectory linkage between the positioning and cleaning mechanism 2 and the laser thickness measurement mechanism 3. The actions between the mechanisms avoid each other and do not interfere with each other. It has a high degree of automation and stable operating rhythm, and is suitable for batch thickness detection operations on electronic seal production lines of the same specifications.
[0069] Working principle:
[0070] S1: The electronic seal to be tested is placed on the upper surface of the carrier 204. In the initial state, the traction rod 217 is located inside the straight groove 219, and the ball bearing at the end of the piston 208 is in contact with the side wall of the stand 201. The PLC controller starts the electric telescopic rod 203, which pulls the carrier 204 to move smoothly laterally along the translation groove of the stand 201. The carrier 204 synchronously drives the main frame 205, the slide plate 206, the cleaning box 207, the piston 208, and the traction rod 217 to move synchronously. During the movement, the ball bearing at the end of the piston 208 slides along the inclined surface of the guide seat 209. Under the guiding force of the inclined surface, the piston 208 slides in a sealed manner inside the inflation tube 220. The gas in the compressed tube inflates the elastic airbag. The elastic airbag pushes the positioning clamping block 210 out of the square groove of the cleaning box 207. The positioning clamping blocks 210 on both sides synchronously center and clamp the electronic seal, realizing automatic positioning and fixing of the workpiece and avoiding displacement and shaking during cleaning.
[0071] S2: The traction rod 217 smoothly transitions from the straight groove 219 into the arc-shaped guide groove 218. Under the constraint of the arc-shaped groove trajectory, the traction rod 217 moves horizontally along with the whole structure while simultaneously generating vertical displacement, causing the suction pipe 216 and the moving part 212 to slide vertically along the inner support 211, thereby driving the hollow part 213 and the cleaning brush 214 to sweep up and down reciprocally; the cleaning brush 214 thoroughly removes floating dust and impurities from the surface and sides of the electronic seal. The external vacuum cleaner, through the suction hose and suction pipe 218... 16 and the suction hole 215 form a negative pressure adsorption, which immediately sucks away the brush dust and prevents secondary adhesion. The clamping and positioning and surface dust removal are completed simultaneously. When the cleaning box 207 moves, it drives the stabilizer 221 to slide along the connecting groove 222. The stabilizer 221 and the connecting groove 222 limit the movement, ensuring that the overall sliding process is smooth without tilting or jamming. After cleaning, the ball 1 disengages from the inclined surface of the guide seat 209, inflates and depressurizes, the elastic airbag retracts, and the positioning clamping block 210 automatically releases the clamp.
[0072] S3: After the electronic seal is cleaned, the cleaning box 207 drives the stabilizer 221 to slide into the area where the connecting groove 1 222 and the connecting groove 2 301 intersect. The traction rod 217 enters the position where the straight groove 219 connects with the connecting groove 2 301. The electric telescopic rod 1 203 stops temporarily. The lower end of the traction rod 217 contacts and engages with the support push block 305, and the electric telescopic rod 2 304 is activated. The support push block 305 is driven to move down along the connecting groove 2 301. The cleaning box 207, stabilizer 221, traction rod 217 and other components move down synchronously with the support push block 305 until the stabilizer 221 reaches the area where the connecting groove 2 301 and the connecting groove 3 302 connect, and the traction rod 217 reaches the area where the connecting groove 2 301 and the connecting groove 4 303 connect. At this time, the slide plate 206 is retracted into the main frame 205 to avoid the thickness measurement space, and the electric telescopic rod 2 304 stops moving.
[0073] S4: Subsequently, the electric telescopic rod 203 continues to feed slightly, causing the stabilizer 221 to slide into the connecting groove 302 and the traction rod 217 to slide into the connecting groove 403. The force-applying component 310 fixed at the top of the stabilizer 221 continuously squeezes the inclined force-bearing surface of the force-bearing component 308 during the movement, driving the T-shaped component 307 to slide upward along the integral component 306, thereby lifting the laser rangefinder 309. After the squeezing stroke is completed, the T-shaped component 307, the force-bearing component 308, and the laser rangefinder 309 smoothly descend and reset under their own gravity. Through the continuous cooperation between the force-applying component 310 and the inclined force-bearing surface, the laser rangefinder 309 forms a small reciprocating displacement in the vertical direction, which can perform thickness scanning measurement on the cleaned electronic seal surface over a wide range and at multiple points, avoiding single-point measurement errors and greatly improving the thickness detection accuracy. The entire mechanism relies on groove linkage, self-realignment, and trajectory guidance, without the need for additional complex drives, to achieve automatic multi-point accurate thickness measurement after cleaning.
[0074] S5: After the electronic seal thickness scanning and measurement process is completed, the inspected electronic seal is manually removed from the carrier 204. Then, the PLC controller controls the electric telescopic rod 203 to reverse its movement, causing the carrier 204 to move laterally back a short distance, allowing the traction rod 217 to re-attach to the upper surface of the support push block 305. The equipment returns to the loading position, where a new electronic seal to be inspected can be placed directly on the carrier 204, completing rapid workpiece replenishment. After replenishment, the electric telescopic rod 304 is activated to lift the support push block 305 upwards, synchronously pushing... Push the traction rod 217, cleaning box 207 and stabilizing component 221 upward as a whole, so that the stabilizing component 221 slides back into the connecting groove 222. The traction rod 217 is accurately reset to the initial position of the straight groove 219. The electric telescopic rod 203 is started again for forward feeding. The bearing seat 204 drives the new electronic seal to be tested to be moved synchronously. The whole process of automatic positioning and clamping of workpiece, surface brushing and cleaning and negative pressure dust collection is repeated. After cleaning, positioning and clamping are completed, the laser rangefinder 309 performs a large-scale multi-point scan to measure the thickness of the cleaned area of the electronic seal again. This cycle is repeated.
