Description

Technical Field

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

[0002] During the production of electrolytic copper foil, a titanium anode is installed in an electrolytic cell, creating an electrochemical potential difference with the copper cathode. When electricity is applied, the titanium anode oxidizes to produce oxygen, while copper ions are reduced to metallic copper on the anode surface, forming 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: The 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, as 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 production 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 processed during the final grain size detection step, most of the time a small piece of the sample to be tested is cut from the produced plate, and then directly placed in the grain size detection equipment for grain size detection processing. Obviously, since only a single sample can be detected and processed, it is impossible to quickly detect multiple test samples in the same batch, resulting in the existing grain size detection equipment being unable to accurately and quickly perform grain size detection processing on the processed titanium anode plates.

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 making any creative efforts shall fall within the scope of protection of the present invention.

[0047] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0048] See also Figure 1-Figure 7 As shown, the present invention is a method for processing ultrafine-grained titanium plates, which includes the following steps:

[0049] S1: Melting: 0.05% boron is added to the titanium sponge and mixed, and then melted three times in a vacuum melting furnace to form a titanium ingot;

[0050] S2: Billet making: adding the smelted titanium ingot into a heating furnace, keeping the temperature at 850-960°C for 45-52 minutes, and then subjecting it to eight-bending and eight-drawing forging to obtain a rough-processed titanium anode billet;

[0051] S3: rolling annealing, the titanium anode slab is subjected to two reversing rolling processes in a rolling mill, and annealing is performed at a furnace temperature of 630°C in an annealing furnace;

[0052] S4: Surface treatment: The titanium anode plate after heat treatment is subjected to surface treatment by sandblasting or polishing;

[0053] S5: Grain size detection: The titanium anode plate to be tested is cut by a cutting device to cut a plurality of titanium alloy sheets for testing, and then quenched, polished and corroded to form a plurality of samples to be tested. The samples to be tested are sequentially placed on the rotating sample turntable 3 in the testing box 1 through the sample loading mechanism 4, and then the grain size detection mechanism 9 in the testing box 1 performs grain size detection on the samples to be tested;

[0054] Among them, in step S5, a sample turntable 3 is rotatably installed on the upper surface of the working box 2 below the inside of the detection box 1, and a plurality of supporting platforms 5 are installed in a circular array on the sample turntable 3. A sample loading mechanism 4 is provided on one side of the sample turntable 3 for placing the sample to be tested on the supporting platform 5. A grain size detection mechanism 9 is installed inside the detection box 1 for performing grain size detection on the test sample placed on the supporting platform 5;

[0055] Specifically, after 0.05% boron is added to the sponge titanium and then smelted, blanked, rolled, annealed and surface treated to form a titanium anode plate with ultrafine grain size, the processed titanium anode plate needs to be quality inspected to ensure that the produced titanium anode plate can reach the required grain size, thereby improving the production efficiency of the copper foil; therefore, after the titanium anode plate surface-treated in step S4 is conveyed, at least six points of the titanium anode plate are sampled by a cutting device, and then the multiple titanium alloy sheets taken out are quenched, polished and corroded to form six samples to be tested, and then the six samples to be tested are placed in turn on the belt conveyor assembly 8 of the conveying box 7 through the clamping hand. The belt conveyor assembly 8 will convey the samples to be tested into the conveying box 7, and then the sample loading mechanism 4 will clamp them in turn and place them on the supporting platform 5 of the continuously rotating sample turntable 3. When the samples to be tested on the supporting platform 5 are transferred to the bottom of the grain size detection mechanism 9, the grain size is The detection mechanism 9 will take metallographic microscope photos of the sample to be inspected, and then transmit the collected images to the central processing unit of the display panel, and then the sample turntable 3 will continue to rotate intermittently, so that the multiple samples to be inspected on the multiple supporting platforms 5 will be transported to the grain size detection mechanism 9 in turn for image capture and labeling, and then after calculation and analysis by the central processing unit, multiple sets of data can be obtained as needed to facilitate data comparison and better ensure the accuracy of the detection, so that the processing method of the present invention can accurately and quickly detect and process the grain size of the titanium anode plate, and the sample to be inspected after inspection can also be quickly removed from the sample turntable 3 through the sample loading mechanism 4. Therefore, there is no need for the operator to manually load and unload the sample to be inspected, which not only prevents 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 enables 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 notched grooves 32 are provided on the outer ring surface of the sample turntable 3, each of the notched grooves 32 is connected to each of the feeding holes 31, and the supporting platform 5 is divided into two circular arc segments and symmetrically arranged above the feeding holes 31. The inner arc surface of the segmentally symmetrical supporting platform 5 is fixed with a supporting bar 51, and the supporting bar 51 is located on both sides of the notched 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 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 set 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. The bottom end of the air guide tube 48 slides downward through the support plate 45 and is connected to the air guide hose, and a rubber suction cup 49 is installed on the top end of the air guide tube 48. 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 guide hose and the air guide pipe 48 can realize the up and down 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 components 8 and then be adsorbed to the lower surface of the sample to be inspected that is being intermittently transported. Then, by continuing to work the driving screw 42, the adsorbed sample to be inspected will be separated from the belt conveyor component 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 guide pipe 48 will slide over the notch groove 32 into the discharge hole 3 1, and the piston rod of the pushing cylinder 46 is retracted, which will cause the rubber suction cup 49 to drive the sample to be tested to drop to the supporting bar 51 for placement. At this time, the rubber suction cup 49 will be detached from the adsorption of the sample to be tested, and then the screw rod 42 will continue to work, so that it will drive the rubber suction cup 49 and other components to slide out of the discharge hole 31, and then the sample turntable 3 will continue to rotate intermittently, so that the controlled supporting platform 5 will continue to rotate until it is aligned 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 on the empty supporting platform 5 for placement. In this way, multiple samples to be tested can be quickly placed on the sample turntable 3 in a safe and sealed environment without manual loading by the operator, thereby further improving the rapid and accurate detection of the sample to be tested by the grain size detection mechanism 9, and will not be affected by the influence of the external environment and the accuracy of its detection data.

[0060] In this embodiment, sliding guide grooves 33 are symmetrically provided on both sides of the 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 surface of the segmentally symmetrical supporting platform 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 part 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 detaches from the push of the segmented support platform 5, the elastic restoring force of the spring part 53 will push the support platforms 5 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 this embodiment, the sample loading mechanism 4 also includes a separation and unloading component 6, which includes 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 supporting 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 an arc protrusion 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 on 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 be aligned with the rubber suction cup 49, the piston rod of the push cylinder 46 will be retracted, causing it to drive 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 will work, causing it to drive the driving gear 65 to rotate, and then the driven gear 64 will drive 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, there will be no interference with the normal rotation of the connecting block 47, and the driven gear 64 that slides up and down is always engaged with the driving gear 65. Since the distance between the arc protrusions 63 at the left and right ends of the connecting block 47 is greater than the distance between the separation plates 62, the rotation of the connecting 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 carrying platforms 5 to slide away from each other, so that the sample to be tested carried on the carrying bar 51 will directly pass through the discharge hole 31. The sample is collected by the sample turntable 3 and falls to the bottom of the sample turntable 3. When the sample to be tested falls off the loading platform 5, the connecting block 47 is reversed or continues to rotate, so that the front and rear arc protrusions 63 rotate to a horizontal state and break away from the push of the symmetrical separation plate 62. Then the connecting block 47 slides and separates from between the symmetrical separation plates 62, and then the spring member 53 pushes the symmetrical loading platforms 5 to move closer to each other, so that the next sample to be tested can be loaded. 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. 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 testing from the supporting platform 5, and thus there is no need for the operator to manually remove the samples to be tested from the testing box 1 after testing, 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 this embodiment, the separation and unloading assembly 6 also includes an electromagnetic ring 66, a metal support 67 and a collecting cylinder 68. The upper surface of the support plate 45 is provided with an annular groove 451, and the bottom of the annular groove 451 is insulated and installed with an electromagnetic ring 66. The bottom end of the cylinder body of the symmetrical pushing 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 the upper surface of the electromagnetic ring 66. A sliding cavity 21 is provided through the front and back of the right side of the working box 2, and a plurality of collecting cylinders 68 are slidably installed in the sliding cavity 21. The upper tube mouth of the collecting cylinder 68 slides correspondingly to the unloading hole 31 on the continuously rotating sample turntable 3. The left wall in the middle of the sliding cavity 21 is provided with an air avoidance groove 22, 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, losing the magnetic attraction to the metal support 67, 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, thereby facilitating the connecting block 47 to 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 up and down, the electromagnetic block on the electromagnetic ring 66 is powered on, magnetically adsorbing the metal support 67, so that the bottom end of the cylinder body of the push cylinder 46 is fixedly connected to the support plate 45, thereby facilitating the piston rod of the push cylinder 46 to stably and quickly drive the rubber suction cup 49 up and down; When the inspection sample is removed, the operator pushes the collection 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 collection tube 68 is aligned with the continuously rotating lower opening, and the diameter of the collection tube 68 is larger than the width of the air-avoiding groove 22, which can support the collection tube 68. Then, when the symmetrical supporting platform 5 slides away, the sample to be inspected will fall from the discharge hole 31 into the collection tube 68 for collection. When the collection tube 68 completes the collection of the batch of samples to be inspected after inspection, the operator takes the collection 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 inspection can be collected and processed in a closed environment, will not cause harm to the environment, and can also be used reasonably.

[0066] In this embodiment, a conveyor box 7 is fixed to the left side wall of the detection box 1, and a belt conveyor assembly 8 is symmetrically fixed in the conveyor box 7. The symmetrical belt conveyor assemblies 8 are located on both sides of the sliding rubber suction cup 49. A display panel is installed above the conveyor box 7.

[0067] Specifically, the operator can use the robot to place the samples to be tested on the extended and symmetrical belt conveyor assembly 8 in sequence. The belt conveyor assembly 8 can transport and carry the samples to be tested. The conveying box 7 can seal and protect the transported samples to be tested. The rubber suction cup 49 will slide to the bottom between the symmetrical belt conveyor assemblies 8 to absorb and transfer the transported samples to be tested, and the gap opened in the lower box body of the conveying box 7 will not interfere with the normal sliding operation of the component corresponding to the rubber suction cup 49.

[0068] In this embodiment, the grain size detection mechanism 9 includes a CCD image sensor 91 and a metallographic microscope 92. The CCD image sensor 91 can be raised and lowered to the top of the detection box 1, and is electrically connected to the central processing unit of the display panel. The metallographic microscope 92 is installed at the front end of the CCD image sensor 91. Specifically, the grain data of multiple groups of samples to be inspected are obtained through the photosensitivity of the metallographic microscope 92 and the image processing of the CCD image sensor 91. The central processing unit analyzes and statistics the grain data to obtain the number of grains and the sample area determined by the magnification of the metallographic microscope 92, and the grain size can be calculated.
