Description

Technical Field

[0001] The invention belongs to the technical field of titanium material processing, and in particular relates to a processing method for an ultrafine-grained titanium plate. Background Art

[0002] In the production process of electrolytic copper foil, the titanium anode is installed in the electrolytic cell to form an electrochemical potential difference with the copper cathode. When the power is turned on, the titanium anode is oxidized to produce oxygen, and the copper ions are reduced to metallic copper on the anode surface to form copper foil.

[0003] The influence of the grain size of titanium anode plate on copper foil production is mainly reflected in the following aspects:

[0004] Surface quality of copper foil: The titanium anode surface with finer grain size can provide more nucleation sites, which is conducive to the uniform deposition of copper, thereby improving the surface flatness of the copper foil and reducing defects.

[0005] Microstructure of copper foil: Titanium anode with smaller grain size is conducive to the refinement of copper foil grains, which can improve the mechanical properties and electrical conductivity of copper foil.

[0006] Efficiency of the electrolysis process: Titanium anodes with appropriate grain size can reduce energy consumption during the electrolysis process because fine grains can reduce the length of the current path and reduce resistance.

[0007] Anode durability: Titanium anodes with uniform grain size wear more evenly during the electrolysis process, which helps to extend the service life of the anode.

[0008] Copper foil production efficiency: Titanium anodes with optimized grain size can improve the production efficiency of copper foil, because better surface quality and microstructure help improve the stability and repeatability of the production process.

[0009] In summary, the grain size of titanium anode plate has an important influence on the production quality and efficiency of copper foil. Proper control of grain size is one of the key factors to improve the performance of copper foil products.

[0010] When the existing titanium anode plates are undergoing the final grain size detection step during processing, most of the time a small piece of the sample to be tested is cut from the produced plate, and then directly placed into the grain size detection equipment for grain size detection processing. Obviously, since only a single sample can be detected and processed, multiple test samples cannot be quickly tested in the same batch, resulting in the inability of existing grain size detection equipment to accurately and quickly perform grain size detection processing on the processed titanium anode plates.

Therefore, there is no need for the operator to manually load and unload the sample to be inspected, which can not only prevent the operator from causing stains on the surface of the sample to be inspected due to manual operation and affecting the accuracy of the detection, but also enable the detection mechanism in the detection box 1 to quickly detect and process multiple detection samples.

[0056] In this embodiment, a plurality of feeding holes 31 are provided in a circular array on the sample turntable 3, and a plurality of notch grooves 32 are provided on the outer ring surface of the sample turntable 3, each of the notch grooves 32 is connected with each of the feeding holes 31, and the bearing platform 5 is divided into two arc segments and symmetrically arranged above the feeding holes 31, and the inner arc surface of the segmentally symmetrical bearing platform 5 is fixed with a bearing bar 51, and the bearing bar 51 is located on both sides of the notch groove 32;

[0057] Specifically, the opening of the notch groove 32 facilitates the sliding of the sample loading mechanism 4 to the center of the discharge hole 31, and places the sample to be tested with a diameter smaller than the discharge hole 31 on the supporting bar 51 on the inner side of the supporting platform 5 for supporting. The supporting bar 51 can be made of transparent glass and a light source component can be installed inside, so that the grain size detection mechanism 9 can accurately and quickly detect the sample to be tested carried on the supporting bar 51; and after the symmetrically segmented supporting platform 5 is opened, the sample to be tested after the grain size detection will directly fall through the discharge hole 31 to the bottom of the sample turntable 3 for discharge and collection, and the operator does not need to manually perform the discharge process.

[0058] In this embodiment, the sample loading mechanism 4 includes a base frame 41, a driving screw 42, a screw slider 43, a support rod 44, a support plate 45, a push cylinder 46, a connecting block 47, an air guide tube 48 and a rubber suction cup 49. The base frame 41 is horizontally fixed to the right side of the detection box 1, and a driving screw 42 is rotatably installed in the base frame 41. The driving screw 42 is sleeved with a screw slider 43 through a screw nut, and the screw slider 43 is slidably arranged in the base frame 41. At least two support rods are vertically fixed to the upper surface of the screw slider 43. 44, and a support plate 45 is fixed to the top surface of the support rod 44, and a left-right symmetrical push cylinder 46 is vertically fixed to the upper surface of the support plate 45, and the upper surfaces of the piston rods of the two push cylinders 46 are connected to the connecting block 47, and an air guide tube 48 is vertically fixed and inserted at the center of the connecting block 47, and the bottom end of the air guide tube 48 slides downward through the support plate 45 to be connected to the air guide hose, and a rubber suction cup 49 is installed at the top end of the air guide tube 48, and the front and rear horizontal width of the connecting block 47 and the diameter of the rubber suction cup 49 are both smaller than the notch width of the notch groove 32;

[0059] Specifically, the driving screw 42 can seriously slide in the length direction of the base frame 41 under the drive of the servo motor, and the screw slider 43 will drive the support plate 45 to slide horizontally left and right through the support rod 44, and the rubber suction cup 49 connected to the air hose and the air pipe 48 can realize up and down lifting movement through the cooperation of the connecting block 47 and the pushing cylinder 46, so that the rubber suction cup 49 can slide between the symmetrical belt conveyor assemblies 8, and then adsorb to the lower surface of the sample to be inspected that is being intermittently transported, and then through the continued operation of the driving screw 42, the adsorbed sample to be inspected will be separated from the belt conveyor assembly 8, and then the piston rod of the pushing cylinder 46 will extend, and the connecting block 47 will drive the rubber suction cup 49 and the adsorbed sample to be inspected to rise above the upper surface of the supporting platform 5, and the rotation of the sample turntable 3 will align the notch groove 32 corresponding to the supporting platform 5 with the connecting block 47, and then the pushing cylinder 46 and the air pipe 48 will slide over the notch groove 32 and enter the discharge hole 3 1, and the piston rod of the push cylinder 46 is retracted to make the rubber suction cup 49 drive the sample to be tested to drop to the carrying bar 51 for placement and loading. At this time, the rubber suction cup 49 will be detached from the sample to be tested, and then the driving screw 42 will continue to work, so that it drives the rubber suction cup 49 and other components to slide out of the unloading hole 31, and then the sample turntable 3 continues to rotate intermittently, so that the controlled carrying platform 5 continues to rotate to align with the rubber suction cup 49, and then the sliding operation of the rubber suction cup 49 can continue to take the next sample to be tested from the belt conveyor assembly 8 and place it in the empty carrying platform 5 for loading and loading, so that multiple samples to be tested can be quickly loaded and placed on the sample turntable 3 in a safe and sealed environment without manual loading by the operator, so that the grain size detection mechanism 9 can further improve the rapid and accurate detection of the samples to be tested, and the accuracy of its detection data will not be affected by the influence of the external environment.

[0060] In this embodiment, sliding guide grooves 33 are symmetrically provided on both sides of the material discharge hole 31, and guide sliders 52 are slidably installed in the sliding guide grooves 33. The symmetrical guide sliders 52 are respectively fixed to the bottom surfaces of the segmentally symmetrical bearing platforms 5, and the side surfaces of the guide sliders 52 are connected to the groove walls of the sliding guide grooves 33 through spring members 53.

[0061] Specifically, after the grain size test of the sample to be tested is completed, the sample turntable 3 drives the tested sample to be aligned with the rubber suction cup 49. At this time, part of the structure of the sample loading mechanism 4 will push the segmented symmetrical support platform 5 to separate the two, and the sliding support platform 5 will drive the guide slider 52 to slide in the sliding guide groove 33, and the spring member 53 will be compressed, and then the separated support platform 5 will separate the sample to be tested on the support platform 5 from the support, so that it falls to the bottom through the discharge hole 31 for collection, and when the partial structure is separated from the push of the segmented support platform 5, the elastic restoring force of the spring member 53 will push the support platform 5 to move closer to each other through the guide slider 52, so as to facilitate the load test of the next batch of samples to be tested.

[0062] In the present embodiment, the sample loading mechanism 4 further comprises a separation and unloading assembly 6, which comprises a separation strip 61, a separation plate 62, an arc protrusion 63, a driven gear 64 and a driving gear 65. The outer ring surface of the segmentally symmetrical carrier platform 5 is fixed with a separation strip 61, and the separation strip 61 extends out of the outer ring surface of the sample turntable 3. The lower surface of the separation strip 61 is fixed with a separation plate 62, and the symmetrical separation plates 62 are located on the outer ring surface of the sample turntable 3. The left and right ends of the connecting block 47 are respectively fixed with arc protrusions 63, and the distance between the two arc protrusions 63 is greater than the distance between the symmetrical separation plates 62. The outer ring surface of the bottom end of the air guide tube 48 is fixed with a driven gear 64, and the side surface of the driven gear 64 is meshed with a driving gear 65, the height of the driving gear 65 is greater than the height of the driven gear 64, the driving gear 65 is connected to the output shaft of the servo motor fixed to the lower surface of the support plate 45, and the bottom end of the air guide tube 48 is rotatably connected to the air guide hose;

[0063] Specifically, when the sample to be tested is transported to align with the rubber suction cup 49, the piston rod of the push cylinder 46 will be retracted, so that it drives the connecting block 47 to drop below the upper surface of the sample turntable 3, and then the connecting block 47 will slide into between the symmetrical separation strips 61. At this time, the servo motor controlling the lower surface of the support plate 45 works, so that it drives the driving gear 65 to rotate, and then the driven gear 64 drives the connecting block 47 to rotate through the air guide tube 48. Since the air guide tube 48 and the support plate 45 can rotate and slide, and the height of the driving gear 65 is greater than that of the driven gear 64, Therefore, the normal rotation of the connection block 47 will not be interfered, and the driven gear 64 sliding up and down will always be meshed with the driving gear 65. Since the distance between the arc protrusions 63 at the left and right ends of the connection block 47 is greater than the distance between the separation plates 62, the rotation of the connection block 47 will drive the left and right horizontal arc protrusions 63 to rotate to a front-to-back horizontal state, and then the rotation of the arc protrusions 63 will cause the symmetrical separation plates 62 to slide away from each other, and then the separation strips 61 will drive the symmetrical and segmented bearing platforms 5 to slide away from each other, so that the sample to be tested carried on the bearing strip 51 will directly pass through the discharge hole 31. The sample falls to the bottom of the sample turntable 3 for collection. When the sample to be tested falls off the carrying platform 5, the connecting block 47 reverses or continues to rotate, so that the front and rear arc protrusions 63 rotate to a horizontal state to break away from the push of the symmetrical separation plate 62, and then the connecting block 47 slides and separates from between the symmetrical separation plates 62, and then the spring member 53 pushes the symmetrical carrying platforms 5 to approach each other, so that the next sample to be tested can be carried. When the air guide tube 48 drives the connecting block 47 to rotate, the push cylinder 46 on the connecting block 47 will rotate synchronously, so that it will not interfere with the rotating connecting block 47, and then The cooperation between the air guide tube 48 and the rubber suction cup 49 can not only clamp the samples to be tested transported on the belt conveyor assembly 8 and transfer them to the supporting platform 5 for carrying, but also the air guide tube 48 can drive the connecting block 47 to rotate, so that it drives the symmetrical supporting platform 5 to be pushed and separated through the symmetrical separation plate 62, thereby facilitating the rapid collection of the samples to be tested after being dropped from the supporting platform 5, and thus there is no need for the operator to manually take the samples to be tested after being tested out of the testing box 1, thereby further improving the grain size detection equipment's ability to quickly perform grain size detection on multiple batches of samples to be tested.

[0064] In the present embodiment, the separation and unloading assembly 6 further comprises an electromagnetic ring 66, a metal support 67 and a collecting tube 68. An annular groove 451 is provided in an annular manner on the upper surface of the support plate 45, and an electromagnetic ring 66 is insulated and installed at the bottom of the annular groove 451. The bottom end of the cylinder body of the symmetrical push cylinder 46 is insulated and connected with a metal support 67, and the bottom end of the metal support 67 is downwardly inserted into the annular groove 451 and contacts with the upper surface of the electromagnetic ring 66. A sliding cavity 21 is provided through the front and rear of the right side of the working box 2, and a plurality of collecting tubes 68 are slidably installed in the sliding cavity 21. The upper tube mouth of the collecting tube 68 corresponds to the unloading hole 31 on the continuously rotating sample turntable 3 in sliding manner. An air avoidance groove 22 is provided on the left side wall in the middle of the sliding cavity 21, and a base frame 41 is provided in the avoidance groove.

[0065] Specifically, when the push cylinder 46 needs to rotate synchronously with the connecting block 47, the electromagnetic block on the electromagnetic ring 66 is powered off, and the magnetic attraction to the metal support 67 is lost, so that the bottom end of the cylinder body of the push cylinder 46 is separated from the fixed connection with the support plate 45, so that the connecting block 47 can drive the push cylinder 46 to rotate synchronously; and when the piston rod of the push cylinder 46 needs to be extended to push the rubber suction cup 49 to rise and fall, the electromagnetic block on the electromagnetic ring 66 is powered on, and the metal support 67 is magnetically attracted, so that the bottom end of the cylinder body of the push cylinder 46 is fixedly connected to the support plate 45, so that the piston rod of the push cylinder 46 can stably and quickly drive the rubber suction cup 49 to rise and fall through the connecting block 47; when it is necessary to wait for the detection When the inspection sample is removed, the operator pushes the collecting tube 68 from the sliding cavity 21 on the back of the working box 2 into the air-avoiding groove 22, so that the upper tube mouth of the collecting tube 68 is aligned with the continuously rotating lower drop mouth, and the diameter of the collecting tube 68 is larger than the width of the air-avoiding groove 22, which can support the collecting tube 68. Then, when the symmetrical supporting platform 5 slides away, the sample to be inspected will fall from the discharge hole 31 to the collecting tube 68 for collection. When the collecting tube 68 completes the collection of the samples to be inspected after the inspection of this batch, the operator takes the collecting tube 68 out of the air-avoiding groove 22 from the front cavity mouth of the sliding cavity 21 for storage, so that the samples to be inspected after the inspection can be collected and processed in a closed environment, will not cause harm to the environment, and can also be used reasonably.
