Description

Technical Field

[0001] The invention relates to the technical field of corrosion foil production detection, in particular to a detection device for production and processing of high specific volume corrosion foil. Background Art

[0002] Corrosion foil usually refers to a film or foil used to protect materials in corrosion experiments or production processes. Its main function is to protect the surface of the substrate from direct contact with corrosive substances, or to serve as a control material in corrosion experiments. Common corrosion foils include aluminum foil and nickel foil, etc., and high specific volume corrosion foil is a corrosion foil with a higher specific surface area. It is usually used to increase the contact area and reaction efficiency of materials in corrosion reactions. This kind of foil increases its specific surface area through specific processes such as microporation and surface roughening, thereby improving its performance in corrosion or electrochemical reactions.

[0003] The thickness of corrosion foils depends on their specific application and material type. Typically, their thickness ranges from a few microns to hundreds of microns. For example, corrosion foils used in batteries and fuel cells may be between 10-100 microns, while thinner foils may be used in laboratory research. The choice of thickness will affect its corrosion behavior and performance, so during the corrosion foil production process, its thickness needs to be tested.

[0004] For example, announcement number CN118067048B discloses an aluminum foil flatness detection device and method, wherein the first U-shaped seat, the first U-shaped seat and the fifth U-shaped seat are respectively provided with detachable and rotatable winding rollers, an aluminum foil roll is wound on the outer surface of the winding roller, the second U-shaped seat and the fourth U-shaped seat are respectively provided with transmission rollers for tensioning the aluminum foil roll, the third U-shaped seat is provided with a visual detector for detecting the flatness of the aluminum foil, and when the second U-shaped seat moves backward, the third U-shaped seat, the fourth U-shaped seat and the fifth U-shaped seat can be formed to move backward at equal distances, so that the transmission roller and the visual detector move downward synchronously.

[0005] When the detection device is in use, when the first U-shaped seat, the second U-shaped seat, the third U-shaped seat, the fourth U-shaped seat and the fifth U-shaped seat are equidistantly spread out, the aluminum foil roll can be normally detected. The winding roller is detachably mounted on the corresponding first U-shaped seat and the fifth U-shaped seat, so as to facilitate the disassembly and replacement of the aluminum foil roll before or after detection. The aluminum foil roll on the winding roller of the first U-shaped seat can be uniformly moved and wound on the winding roller of the fifth U-shaped seat through the rotatable winding roller; the aluminum foil can be tensioned and lifted up through the transmission rollers arranged on the second U-shaped seat and the fourth U-shaped seat, so that a flat end surface is formed in the middle of the two transmission rollers for easy detection; the flatness of the aluminum foil can be detected through the arranged visual detector; when the device is idle, the first U-shaped seat is fixed by the foot brake moving wheel, and when the second U-shaped seat moves backward, the third U-shaped seat, the fourth U-shaped seat and the fifth U-shaped seat can be equidistantly moved backward, so that the transmission roller and the visual detector move downward synchronously, so that the device is in a fully folded state, and the occupied space is reduced.

[0006] During the detection process, the device uses a visual detector to detect the flatness of the aluminum foil surface. The visual detector uses parallel light irradiation, which has low light intensity and is greatly affected by the external environment. During monitoring, the reflection speed of parallel light is slow and the detection efficiency is low. In addition, when using parallel light detection, the receiving points of the reflection of the parallel light beam are multiple points, which will affect the overall detection accuracy and thus reduce the accuracy of the detection.

[0007] Therefore, a new type of high specific capacity corrosion foil production and processing detection device can be used to solve the shortcomings of the prior art. Summary of the invention

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] 1. During the monitoring process of the corrosion foil, the detection device for the production and processing of high specific capacity corrosion foil can change the focus of the laser by setting the regulator, so as to detect the thickness of the corrosion foil. With the arc-shaped color scattering disk, the single laser beam can be diverged into an arc-shaped scanning beam, which is used to detect the flatness of the surface of the corrosion foil. It has strong functionality. At the same time, the change of the laser focus can also change the intensity of the laser scattered light, ensuring that the laser scattered light is at the highest intensity, so as to provide sufficiently clear light reflection. At the same time, changing the laser focus can also meet the detection of corrosion foils of different thicknesses, and has a wider range of applications.

[0026] 2. During the monitoring process of the corrosion foil, the detection device for the production and processing of high specific capacity corrosion foil sets a filter to filter the laser light source emitted by the laser, reduce the influence of external light on the laser, and improve the concentration of the laser. At the same time, it cooperates with the arc-shaped light receiving strip to reflect the light beam to a single point, thereby improving the singleness and stability of the light beam collection, thereby improving the accuracy of laser detection.

[0027] 3. During the monitoring process of the corrosion foil, the detection device for the production and processing of high specific capacity corrosion foil can adjust the tension of the corrosion foil during the detection process by setting the bottom electric push rod, tension wheel and pressure sensor rod to ensure that the tension of the corrosion foil is at the optimal tension level, thereby improving the accuracy of corrosion foil detection.

[0028] 4. During the monitoring process of the corrosion foil, the detection device for the production and processing of high specific capacity corrosion foil can provide a damper and a sliding rod to buffer the movement of the regulator. When the bidirectional motor changes direction, the vibration of the regulator is reduced, thereby reducing the jitter of the laser beam emitted by the laser, improving the stability of the laser beam, and helping to improve the accuracy of monitoring.

[0029] 5. During the monitoring process of the corrosion foil, the detection device for the production and processing of high specific volume corrosion foil sets a bidirectional motor to drive the regulator and the laser to rotate, and then drives the corrosion foil to be reeled and unwound through a unidirectional motor to realize detection during the reeling and unwinding process. At this time, the laser beam will perform S-shaped sampling detection on the corrosion foil. The speed of the bidirectional motor can be changed to change the detection interval, and the sampling path is linear rather than multi-point, which can effectively improve the detection accuracy and is used to detect the thickness and flatness range of qualified corrosion foil.

[0030] 6. During the monitoring process of the corrosion foil, the detection device for the production and processing of the high specific volume corrosion foil is equipped with a cylindrical roller and a traction wheel, and the traction wheel is designed to be inclined. The movement of the corrosion foil drives the traction wheel to rotate. According to the decomposition of the force, the traction wheel can straighten the bent corrosion foil after the corrosion foil detection is completed, ensuring that the corrosion foil remains straight during winding, which is convenient for normal winding.

[0031] In summary, the device uses laser to detect the thickness and flatness of corrosion foils of different thicknesses. The light intensity is high, the stability is high, the light beam reflection speed is fast, and the detection efficiency is high. In the detection process, the reflection point of the laser beam is received at the same point, the receiving point is single and stable, and the detection accuracy is high. In addition, the tension of the corrosion foil can be adjusted according to the actual situation of the corrosion foil during the detection process to ensure that the tension of the corrosion foil is within the optimal detection range, thereby further improving the detection accuracy.

DETAILED DESCRIPTION

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] Example 1: Reference Figure 1-Figure 5 A detection device for the production and processing of high specific volume corrosion foil includes a bracket 1 and a bracket 2; a feeding part, which is used for conveying the corrosion foil during the production process, unrolling the rolled corrosion foil for monitoring, and then rewinding the corrosion foil after the monitoring is completed, and the feeding part includes a rewinding and unwinding assembly fixedly installed on the bracket 1.

[0051] The reeling and winding assembly includes two placing plates 4 fixedly mounted on a bracket 1, two mounting frames 11 are fixedly mounted on the two placing plates 4, a driving wheel 9 is mounted on the two matching mounting frames 11 for common rotation, a unidirectional motor 10 is fixedly mounted on the two mounting frames 11, the driving ends of the two unidirectional motors 10 are fixedly connected to the corresponding driving wheels 9, and a clamping mechanism matching the corresponding driving wheels 9 is installed on the two matching mounting frames 11.

[0052] The rotation of the driving end of the unidirectional motor 10 will drive the driving wheel 9 to rotate. The two driving wheels 9 have the same direction of rotation, but the rotation speed of the two driving wheels 9 changes linearly. The rotation speed of the winding driving wheel 9 gradually slows down during the detection process, and the rotation speed of the unwinding driving wheel 9 gradually speeds up. This is because when winding and unwinding, the diameter of the unwinding corrosion foil gradually decreases, while the diameter of the winding gradually increases. To ensure the synchronization of winding and unwinding, the speed needs to be adjusted to prevent the corrosion foil from being broken.

[0053] The clamping mechanism includes two sliding blocks 12 slidably installed on two mounting frames 11 through a slide groove, and a pressure wheel 8 cooperating with a driving wheel 9 is installed on the two sliding blocks 12 for common rotation. A magnet 13 is fixedly installed on each of the two sliding blocks 12, and a magnet 2 14 that repels the corresponding magnet 1 13 is fixedly installed in each of the two slide grooves.

[0054] The repelling magnet 13 and magnet 2 14 make the pressing wheel 8 always press against the driving wheel 9, so that the corrosion foil on the driving wheel 9 can be clamped, which can not only improve the stability of the corrosion foil when it moves, but also squeeze and flatten the corrosion foil to ensure that the corrosion foil remains straight during the detection process, which is beneficial to improve the thickness of the corrosion foil and the accuracy of flatness detection. The use of magnet 13 and magnet 2 14 here has higher durability, no wear, adjustable force and better controllability (just adjust the spacing). In addition, the non-contact characteristics of magnet 13 and magnet 2 14 reduce friction, thereby improving the stability and reliability of the system.

[0055] Embodiment 2: This embodiment is different from the embodiment 1 in that: Figure 1-Figure 2 , Figure 5-Figure 15 , the detection part performs laser detection on the unfolded corrosion foil to check the flatness of the corrosion foil surface and the thickness of the corrosion foil. A connecting frame 22 is installed on the bracket 2 through an adjustment component;

[0056] The adjustment component includes a top plate 6 fixedly installed on the middle plate 5 through a plurality of limit columns 17, a top electric push rod 15 is fixedly installed on the top plate 6, a sliding plate 7 is slidably installed on the plurality of limit columns 17, the telescopic end of the top electric push rod 15 is fixedly connected to the sliding plate 7, a plurality of telescopic rods 16 are fixedly installed between the sliding plate 7 and the top plate 6, and the sliding plate 7 is fixedly connected to the connecting frame 22.

[0057] The driving end of the top electric push rod 15 is extended and retracted to drive the sliding plate 7 to slide on the limiting column 17, thereby driving the connecting frame 22 to move. During the movement of the sliding plate 7, the sliding plate 7 will drive the telescopic rod 16 to extend and retract. The limiting column 17 can ensure that the sliding plate 7 maintains stable movement, and the function of the telescopic rod 16 is to further improve the stability of the sliding plate 7 and reduce the amplitude of the sliding plate 7 when it moves.

[0058] The regulator 18 is installed on the connecting frame 22 through a rotating assembly, and the rotating assembly includes a bidirectional motor 23 fixedly installed on the connecting frame 22. A connecting shaft 25 is fixedly installed on the driving end of the bidirectional motor 23. The connecting shaft 25 and the connecting frame 22 are rotatably connected through a permanent magnetic bearing 24. The connecting shaft 25 and the regulator 18 are fixedly connected. A buffer mechanism is installed between the regulator 18 and the connecting frame 22.

[0059] The driving end of the bidirectional motor 23 drives the connecting shaft 25 to rotate, thereby driving the laser 27 to rotate, so that the laser 27 swings left and right within a fixed range. As the laser 27 swings, the corrosion foil will be laser scanned and detected. If the corrosion foil moves during scanning, the laser path on the corrosion foil is S-shaped. If the corrosion foil does not move, the laser performs indirect linear detection. At this time, two modes of detection can be performed during laser detection. The switching of the two modes can be used for monitoring to reduce detection errors.

[0060] The regulator 18 is a device used to adjust and control the laser beam. It can adjust the intensity, direction or focus of the laser. It is widely used in scientific research, industrial processing, medical equipment and other fields (because it is an existing technology, the specific principle will not be explained here). It cooperates with the laser 27 to adjust the intensity and focal length of the laser beam. When detecting corrosion foils of different thicknesses, it can be automatically adjusted (the specific control adjustment can be set through the control box 3, the control box 3 is fixedly installed on the bracket 2, and can control electrical equipment such as the unidirectional motor 10, the bidirectional motor 23 and the top electric push rod 15. The specific control method is an existing technology and will not be explained in detail here).

[0061] The connecting shaft 25 and the connecting frame 22 are rotatably connected via a permanent magnetic bearing 24, which can greatly reduce the friction force when the connecting shaft 25 rotates, thereby greatly reducing the resistance when the connecting shaft 25 rotates. Since friction is an unstable resistance, reducing friction force can make the connecting shaft 25 more stable when rotating, reduce the vibration amplitude of the laser beam emitted by the laser 27, and make the laser beam more stable when scanning (the permanent magnetic bearing 24 is an existing technology, and its specific structure is not explained here).

[0062] Reference Figure 8-Figure 9 The buffer mechanism includes two dampers 26 fixedly mounted on the connecting frame 22 , and a sliding rod 31 is slidably mounted on each of the two dampers 26 . The two sliding rods 31 are fixedly connected to the regulator 18 .

[0063] The purpose of designing this part is to provide mobile buffering for the regulator 18. When the driving end of the bidirectional motor 23 changes direction, the vibration of the regulator 18 is reduced, thereby reducing the jitter of the laser beam emitted by the laser 27, improving the stability of the laser beam, and helping to improve the accuracy of monitoring (the damper 26 is a common buffering device and is not elaborated here).

[0064] A laser 27 is fixedly mounted on the regulator 18, and a scattering assembly is mounted on the laser 27. The scattering assembly includes a filter 29 fixedly mounted on the laser 27, and a fixing ring 30 is fixedly mounted on the filter 29. An arc-shaped scattering disk 32 is mounted on the fixing ring 30 for damping rotation (the damped rotation is a rotation connection, but has a certain damping. The arc-shaped scattering disk 32 can only be rotated when a force of a certain intensity is applied. In this way, the arc-shaped scattering disk 32 can be suspended at any position. This structure is an existing structure, and a rubber ring can be set at the rotation connection between the arc-shaped scattering disk 32 and the fixing ring 30 to achieve a damping effect).

[0065] When performing laser scanning detection, the arc-shaped dispersion disk 32 is rotated to the side of the filter 29 so that the laser beam does not pass through the arc-shaped dispersion disk 32. If a preliminary scanning detection is performed, the light intensity requirement is lower at this time. The laser beam will be dispersed under the action of the arc-shaped dispersion disk 32. The light emitted from the bottom of the arc-shaped dispersion disk 32 is fan-shaped. This is a static scan and detection can be performed when the corrosion foil moves, so as to detect any position of the corrosion foil specific surface.

[0066] The side and top of the arc-shaped scattering disk 32 are fixedly attached with shading plates 28. The shading plate 28 at the top is provided with a light-transmitting hole matched with the filter 29. A baffle rod matched with the arc-shaped scattering disk 32 is fixedly installed on the fixing ring 30 (the function of the baffle rod is to limit the arc-shaped scattering disk 32 to ensure that the arc-shaped scattering disk 32 remains vertical during operation); the functions of the shading plate 28 and the filter 29 are to reduce the influence of external light sources on the laser beam and improve the stability of laser beam detection.

[0067] A docking nut 44 is fixedly mounted on the filter 29 , a docking threaded ring 46 threadedly rotatably connected to the docking nut 44 is fixedly mounted on the laser 27 , and a limit nut 45 matching the docking nut 44 is threadedly rotatably mounted on the docking threaded ring 46 .

[0068] When installing the filter 29, it is necessary to rotate the docking nut 44 on the docking threaded ring 46. Due to the long-term installation and disassembly of the filter 29, the docking nut 44 and the docking threaded ring 46 will be worn to a certain extent. At this time, the limit nut 45 can be used to limit the rotation depth of the docking nut 44 to ensure that after the arc scattering disk 32 is fixed, the projection of the arc scattering disk 32 on the corrosion foil is perpendicular to the corrosion foil, so as to avoid the situation where the arc scattering disk 32 is offset and causes the detection result to be too large.

[0069] A center plate 5 is fixedly installed on the bracket 2, and a mounting plate 19 is slidably installed on the center plate 5 through a plurality of limit rods 21. An arc plate 41 is installed on the mounting plate 19, and a mounting groove is provided on the mounting plate 19. A clamping block 43 matching the mounting groove is fixedly installed on the arc plate 41. A locking plate 37 is rotatably installed on the mounting plate 19, and a nut is fixedly installed on the locking plate 37. A locking screw 38 matching the clamping block 43 is threadedly rotatably installed on the nut.

[0070] Insert the block 43 into the installation groove and move the block 43 to the bottom of the installation groove. Then rotate the locking plate 37 to block the port of the installation groove. Then rotate the locking screw 38 so that the locking screw 38 abuts against the block 43 to lock the block 43.

[0071] A light receiving strip 42 matched with the laser 27 is installed on the arc plate 41, a tension control assembly is installed between the middle plate 5 and the arc plate 41, and the tension control assembly includes two side baffles 39 fixedly installed on the arc plate 41, two pressure sensing rods 40 are fixedly installed on the two side baffles 39, a bottom electric push rod 20 is fixedly installed at the bottom of the middle plate 5, the bottom electric push rod 20 is connected to the pressure sensing rod 40 through a controller, and the telescopic end of the bottom electric push rod 20 is fixedly connected to the mounting plate 19;

[0072] A tension wheel 33 is rotatably mounted on the mounting plate 19, a cylindrical roller 34 is fixedly mounted on the mounting plate 19, two annular grooves are provided on the cylindrical roller 34, a plurality of traction wheels 35 are rotatably mounted in both annular grooves, and the traction wheels 35 in the two annular grooves are all inclined in design.

[0073] Since the corrosion foil is in an arc shape after being deformed by the pressure sensing rod 40, if an ordinary cylindrical roller is used to transfer the corrosion foil, the corrosion foil may not be stretched in time, resulting in the corrosion foil being folded after being rolled up, affecting the use of the corrosion foil. Two sets of traction wheels 35 with different inclination directions are designed to stretch the corrosion foil (the operating principle of the traction wheel 35 is the component force of the friction force, which not only generates a force in the same direction as the movement of the corrosion foil, but also generates a component force on both sides of the cylindrical roller 34, which can stretch the corrosion foil), ensuring that the corrosion foil is in a flat state when rolled up.

[0074] The etching foil passes between the driving wheel 9 and the pressing wheel 8, then abuts against the upper surface of the tension wheel 33, passes between the arc plate 41 and the pressure sensing rod 40, abuts against the pressure sensing rod 40, then passes closely against the upper surface of the cylindrical roller 34, and passes out from between another driving wheel 9 and the pressing wheel 8.

[0075] The pressure sensing rod 40 senses the tension of the corrosion foil, and then controls the bottom electric push rod 20 to operate through the controller, so that the mounting plate 19 moves, thereby driving the tension wheel 33 to move. Since the movement speed of the corrosion foil is fixed, the position of the tension wheel 33 is adjusted, that is, the movement path of the corrosion foil is adjusted, so as to achieve the purpose of adjusting the tension of the corrosion foil and ensure that the tension of the corrosion foil is within the optimal tension range, so as to improve the accuracy of the detection (the optimal tension is a known value, factory set, and the optimal tension value of corrosion foils of different materials is different).

[0076] The arcs of the arc plate 41 and the arc scattering disk 32 are concentric circles, both of which are arcs with the driving end of the bidirectional motor 23 as the axis. This can ensure that the laser beam is reflected after being irradiated on the corrosion foil to pass through the laser 27 (the laser 27 can not only emit lasers, but also receive lasers. It is an existing laser system, and different components are used internally for operation, which will not be explained in detail here), realizing single-point reception with higher accuracy (the corrosion foil has a certain light transmittance, and the light beam passing through the corrosion foil is received by the light receiving strip 42 to detect the thickness and flatness of the corrosion foil. This is an existing technology, and its principle will not be explained in detail).

[0077] The specific operation steps of this device are as follows:

[0078] Installation of etching foil: The etching foil passes between the driving wheel 9 and the pressing wheel 8, then abuts against the upper surface of the tension wheel 33, passes between the arc plate 41 and the pressure sensing rod 40, abuts against the pressure sensing rod 40, then passes closely against the upper surface of the cylindrical roller 34, and passes out from between another driving wheel 9 and the pressing wheel 8.

[0079] Thickness and flatness detection of corrosion foil:

[0080] Preliminary detection (used to detect the qualified rate of the corroded foil): The laser 27 is adjusted to the optimal state through the regulator 18. The laser light beam emitted by the laser 27 will be dispersed by the arc-shaped dispersion disk 32. The light emitted from the bottom of the arc-shaped dispersion disk 32 is fan-shaped. At this time, it is a static scan. The detection can be performed when the corroded foil moves, so as to detect any position of the specific surface of the corroded foil.

[0081] Precision detection (used to detect the deviation range of the thickness and flatness of the corrosion foil, and measure the thickness at a specific position): rotate the arc-shaped dispersion disk 32 to the side of the filter 29. The first mode: single linear detection, the corrosion foil does not move, start the bidirectional motor 23, and the bidirectional motor 23 drives the laser 27 to rotate back and forth through the connecting shaft 25. At this time, the laser beam is a single high-intensity laser beam. The laser beam will perform a linear scan on the corrosion foil. After the scanning is completed, the corrosion foil will be moved to form an intermittent linear detection to detect the thickness and flatness of the corrosion foil on this line; in the second mode, the corrosion foil moves. Due to the movement of the corrosion foil, the bidirectional motor 23 still drives the laser 27 to rotate back and forth through the connecting shaft 25. At this time, the laser beam will form an S-shaped path detection on the corrosion foil, which can quickly detect the location of the thickness and flatness deviation. The speed of the bidirectional motor 23 can be changed to adjust the density of the S-shaped route.
