The method involves using a clamp to vertically fix chopsticks with titanium tips in a receiving groove, and injecting a heat-conducting liquid into the groove so that the portion of the chopsticks other than the titanium tips is submerged in the liquid. The focus of a nanosecond laser galvanometer in the laser assembly is adjusted to align with the titanium chopstick tip, and the galvanometer is controlled to scan the surface of the titanium chopstick tip according to preset laser parameters, thus hardening the surface.

Description

TECHNICAL FIELD

[0001] The application relates to the technical field of metal processing, in particular to a titanium chopstick head laser surface hardening method, a controller and a hardening device. BACKGROUND

[0002] Pure titanium tableware becomes the best metal tableware because of its light weight and complete non-toxicity. However, pure titanium is soft and easy to scratch ceramic bowls, causing wear of the titanium chopsticks and affecting the appearance of the ceramic bowls. Therefore, hardening the surface of the titanium chopstick head becomes an important process in the production of titanium chopstick heads.

[0003] Currently, the main methods for hardening the surface of the titanium chopstick head include anodic oxidation hardening and high-temperature oxidation hardening.

[0004] However, the oxidation layer structure is loose by anodic oxidation hardening and high-temperature oxidation hardening, and the oxidation layer is still prone to wear during use. SUMMARY

[0005] The application provides a titanium chopstick head laser surface hardening method, a controller and a hardening device, which solves the technical problem that the oxidation layer of the titanium chopstick head is prone to wear, achieves the purpose of improving the structure density of the oxidation layer, and ensures that the titanium chopstick head does not discolor after ten thousand friction experiments.

[0006] In order to achieve the above purpose, the main technical scheme adopted by the application comprises:

[0007] In a first aspect, the application provides a titanium chopstick head laser surface hardening method, which is applied to a hardening device, and the hardening device is provided with a fixing assembly, a laser assembly and a testing assembly. The fixing assembly comprises a containing groove and a fixing clamp. The method comprises the following steps:

[0008] The fixing clamp is used to vertically fix a chopstick with a titanium chopstick head in the containing groove, and a heat-conducting liquid is injected into the containing groove, so that the part of the chopstick other than the titanium chopstick head is placed in the heat-conducting liquid;

[0009] The focal point of the nanosecond laser galvanometer in the laser assembly is aligned with the titanium chopstick head, and the nanosecond laser galvanometer is controlled to scan the surface of the titanium chopstick head according to preset laser parameters, so as to harden the surface of the titanium chopstick head;

[0010] The ceramic sheet in the testing assembly is controlled to scratch the hardened titanium chopstick head, and the scratches on the ceramic sheet are detected. If no scratches are detected, the fixing clamp is loosened, so that the chopstick sinks to the bottom of the heat-conducting liquid and enters the storage area provided at the bottom of the containing groove.

[0011] In this embodiment, by using the fixing clamp to fix the chopsticks and inject the heat-conducting liquid, adjusting the nanosecond laser galvanometer to make its focal point align with the titanium chopstick head, and performing scanning hardening, controlling the ceramic sheet to pass through the hardened titanium chopstick head, and detecting the scratch, the effect of improving the hardening efficiency of the titanium chopstick head is realized.

[0012] In an example, the ceramic sheet has a size covering one titanium chopstick head; controlling the ceramic sheet in the test assembly to pass through the hardened titanium chopstick head comprises:

[0013] Rising the titanium chopstick head currently tested by the fixing clamp by a preset height;

[0014] After controlling the ceramic sheet to move above the titanium chopstick head, and the interaction force between the ceramic sheet and the titanium chopstick head reaches a preset force, controlling the ceramic sheet to move according to a preset trajectory.

[0015] In this example, by controlling the fixing clamp to adjust the position of the titanium chopstick head, and precisely controlling the ceramic sheet to move according to a preset trajectory after the interaction force between the ceramic sheet and the titanium chopstick head reaches a preset force, the effect of testing the hardening effect of the titanium chopstick head one by one is realized, and the test accuracy is improved.

[0016] In an example, the method further comprises:

[0017] If the scratch is detected on the ceramic sheet, a new ceramic sheet is replaced;

[0018] Otherwise, if the scratch is not detected on the ceramic sheet, the ceramic sheet is used to test the next titanium chopstick head.

[0019] In this example, by detecting the scratch on the ceramic sheet and determining whether the ceramic sheet needs to be replaced, the effect of ensuring the test accuracy and improving the test reliability is realized.

[0020] In an example, the ceramic sheet has a size covering all the titanium chopsticks fixed by the fixing clamp of the hardening device; controlling the ceramic sheet in the test assembly to pass through the hardened titanium chopstick head comprises:

[0021] Controlling the ceramic sheet to move above all the titanium chopsticks;

[0022] Rising the fixing clamp of each chopstick to make the interaction force between the chopstick and the ceramic sheet reach a preset force;

[0023] Moving the ceramic sheet according to a preset trajectory.

[0024] In the example, the method for batch testing the surface hardening performance of the titanium chopstick head is realized by moving the ceramic sheet above all the titanium chopstick heads, moving the fixed clamp upward to make the interaction force between each chopstick and the ceramic sheet reach a preset force, and moving the ceramic sheet along a preset trajectory, thereby improving the testing efficiency. Moreover, the testing accuracy of each chopstick is ensured by moving each chopstick upward.

[0025] In an example, the method further comprises:

[0026] If the scratch is detected, the nanosecond laser galvanometer is controlled to scan the titanium chopstick head surface again based on the laser parameters, the titanium chopstick head surface is hardened, and the ceramic sheet in the test assembly is controlled to slide across the hardened titanium chopstick head to detect the scratch on the ceramic sheet.

[0027] The above process is repeated until no scratch is detected on the ceramic sheet.

[0028] In the example, the titanium chopstick head surface hardness effect is improved, and the yield is improved by cyclically performing the operations of hardening and detecting the titanium chopstick head surface until the titanium chopstick head is completed.

[0029] In an example, the laser parameters include at least one of power, scan line width, and scan speed; and the nanosecond laser galvanometer is controlled to scan the titanium chopstick head surface again based on the laser parameters, including:

[0030] The power is increased, and the scan line width and / or the scan speed are decreased.

[0031] The titanium chopstick head surface is scanned again using the adjusted nanosecond laser galvanometer.

[0032] In the example, the effectiveness of the laser parameters is improved, and the titanium chopstick head surface hardening effect is improved by increasing the power, decreasing the scan line width, and decreasing the scan speed to optimize the laser parameters, and using the adjusted laser parameters to control the nanosecond laser galvanometer to scan the titanium chopstick head surface again.

[0033] In an example, the laser parameters include at least one of power, scan line width, and scan speed.

[0034] The power is 25 to 35 watts, the scan line width is 0.03 to 0.06 millimeters, and the scan speed is 300 to 350 millimeters per second.

[0035] In the example, the laser of the nanosecond laser galvanometer is set to narrow line width and slow scanning to perform surface hardening treatment on the titanium chopstick head by setting the laser parameters.

[0036] Secondly, embodiments of this application provide a laser surface hardening device for titanium chopsticks, applied to a hardening equipment. The hardening equipment includes a fixing component, a laser component, and a testing component. The fixing component includes a receiving groove and a fixing clamp. The device includes:

[0037] A fixing module is used to vertically fix chopsticks with titanium tips in the receiving groove using the fixing clamp, and to inject heat-conducting liquid into the receiving groove so that the part of the chopsticks other than the titanium tips is placed in the heat-conducting liquid;

[0038] The laser module is used to adjust the focus of the nanosecond laser galvanometer in the laser assembly to align with the titanium chopstick tip, and to control the nanosecond laser galvanometer to scan the surface of the titanium chopstick tip according to preset laser parameters, thereby hardening the surface of the titanium chopstick tip.

[0039] The detection module is used to control the ceramic plate in the test component to slide across the hardened titanium chopstick tip and detect the scratches on the ceramic plate; if no scratches are detected, the fixing clamp is released so that the chopstick sinks into the bottom of the heat-conducting liquid and enters the storage area set at the bottom of the receiving tank.

[0040] Thirdly, embodiments of this application provide a controller, including: a memory and a processor, wherein the memory and the processor are communicatively connected to each other, the memory stores computer instructions, and the processor executes the computer instructions to perform the method described in any of the above embodiments.

[0051] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0052] Titanium is renowned as "space metal" and "smart metal" due to its superior properties. Its most outstanding advantage is its extremely high strength coupled with a density only 60% that of steel, making it a top-tier material for achieving lightweighting. Furthermore, titanium possesses unparalleled corrosion resistance, particularly against seawater and chloride ions. In addition, titanium exhibits excellent biocompatibility, being non-toxic and hypoallergenic, making it an ideal choice for medical implants such as artificial joints and dental implants. Titanium also maintains good mechanical properties at both high and low temperatures.

[0053] With the maturation of titanium smelting technology, the application of titanium is gradually expanding from high-end fields such as aerospace to the civilian sector. The emergence of pure titanium tableware will replace stainless steel tableware, protecting people's health. Pure titanium tableware is considered the best metal tableware due to its lightweight and completely non-toxic and harmless characteristics. However, titanium is relatively soft and easily scratches harder utensils. In particular, titanium chopsticks can easily leave black titanium powder marks on ceramic bowls, causing wear and tear on pure titanium chopsticks. Currently, scratches and wear are mainly prevented by hardening the surface of titanium chopsticks.

[0054] Currently, there are three methods for surface hardening of titanium chopsticks. The first method is anodizing. Anodizing produces a uniform hardened film, but the film is thin and loose. After repeated use, the oxide film wears down and continues to wear down the inner titanium chopsticks. The second method is high-temperature oxidation. High-temperature oxidation produces a gradient hardened film. However, the film thickness varies, and the film remains loose. The third method is laser oxidation. Laser oxidation produces a dense and uniform oxide film that does not wear down even after repeated use.

[0055] However, the technology of laser oxidation hardening of titanium chopsticks is not yet mature, and the thermal ablation side effects caused by the oxidation process have not been well resolved.

[0056] Therefore, to address this issue, this application proposes a laser surface hardening method for titanium chopstick tips. This method involves fixing chopsticks with titanium tips to a heat-conducting liquid, then using a nanosecond laser galvanometer to perform surface hardening treatment on the exposed titanium chopstick tip surface through a narrow-linewidth slow scanning method. Furthermore, this application can also use a ceramic plate to inspect the surface-hardened titanium chopstick tip; if the inspection fails, the laser parameters of the nanosecond laser galvanometer can be adjusted to perform a second hardening process, ensuring the hardening effect.

[0057] According to an embodiment of this application, a method for laser surface hardening of titanium chopsticks is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed on a controller via a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here. The controller can be a mobile terminal, a personal computer, a server, etc.

[0058] Figure 1 This is a flowchart illustrating a method for laser surface hardening of titanium chopsticks tips, provided in an embodiment of this application. This method is applied to a hardening device. The hardening device includes a fixing component, a laser component, and a testing component. The fixing component includes a receiving groove and a fixing clamp, with the fixing clamp disposed inside the receiving groove. Figure 1As shown, with the controller as the execution subject, the process includes the following steps:

[0059] S101. Use a fixing clamp to vertically fix the chopsticks with titanium tips in the receiving groove, and inject heat-conducting liquid into the receiving groove so that the part of the chopsticks other than the titanium tips is placed in the heat-conducting liquid.

[0060] For example, the controller can control the clamp to fix the chopsticks with titanium tips vertically in the receiving groove with the titanium tips facing upwards. Then, the controller can inject a heat-conducting liquid into the receiving groove, submerging the body of the chopsticks and exposing only the titanium tips to the air.

[0061] In one implementation, this application hardens the surface of the titanium chopstick tip. Therefore, the chopsticks referred to in this application are chopsticks with titanium tips whose head portion is made of pure titanium material.

[0062] In one implementation, the fixing clip is a structure used to secure chopsticks. For example, the fixing clip can be a clamp, a buckle, a spring clip, etc. This fixing clip is used to firmly secure the chopsticks in a designated position, preventing them from moving during subsequent operations.

[0063] In one implementation, the receiving tank is a container with a certain volume and shape. This receiving tank can be used to hold the main body of chopsticks. Simultaneously, it can also be used to hold a heat-conducting liquid. Optionally, the shape and size of the receiving tank can be designed according to actual needs.

[0064] In one implementation, the thermally conductive liquid is a liquid capable of rapidly conducting heat; common thermally conductive liquids include water and thermally conductive oil. Different thermally conductive liquids have different thermal conductivity and boiling points, and can be selected according to specific process requirements. This thermally conductive liquid is used to conduct heat through the main body of the chopsticks during the subsequent hardening process, preventing thermal parasitic lines from appearing on the titanium chopstick tips due to overheating during hardening.

[0065] Optionally, such as Figure 2 As shown, the chopsticks on the left are the result of using a heat-conducting liquid for heat conduction followed by laser hardening of the titanium chopstick tip surface. The chopsticks on the right are the result of using a laser to harden the titanium chopstick surface without using a heat-conducting liquid. The dark substance adhering to the surface of the titanium chopstick tip on the right is the thermal parasitic texture. The comparison between the two chopsticks clearly shows that placing the chopsticks in a heat-conducting liquid before laser hardening can completely eliminate thermal parasitic textures and improve the aesthetics of the hardened product.

[0066] In one implementation, the controller can use an electric or pneumatic device to control the opening and closing of the clamp. Once the chopsticks reach the clamp's position, the controller can fix them by controlling the clamp's opening and closing. Alternatively, the clamp can be manually adjusted, allowing manual operation to tighten the clamp around the chopsticks.

[0067] In one implementation, the chopsticks can be moved to the corresponding position of the fixed clamp via a conveyor belt or similar means. Alternatively, the chopsticks can be placed into the corresponding position of the fixed clamp manually.

[0068] In one implementation, the controller can determine the junction position between the titanium chopstick tip and the body of the chopstick after the chopstick is fixed. The controller can use an automatic filling device to inject heat-conducting liquid into the receiving tank so that the height of the heat-conducting liquid reaches the junction position between the titanium chopstick tip and the body, thereby ensuring that the body of the chopstick is submerged in the heat-conducting liquid while the titanium chopstick tip is exposed. Alternatively, the heat-conducting liquid can be injected manually.

[0069] In one implementation, when multiple chopsticks are fixed in the receiving groove, the controller can obtain the junction position between the titanium chopstick tips and the main body of the multiple chopsticks. If the multiple junction positions are inconsistent, the controller can adjust the junction positions by adjusting the fixed position of the chopsticks, thereby ensuring that the junction positions of all chopsticks are at the same height.

[0070] S102. Adjust the focus of the nanosecond laser galvanometer in the laser assembly to align with the titanium chopstick tip, and control the nanosecond laser galvanometer to scan the surface of the titanium chopstick tip according to the preset laser parameters to harden the surface of the titanium chopstick tip.

[0071] For example, the controller adjusts the focus of the nanosecond laser galvanometer in the laser assembly to precisely align it with the titanium chopstick tip. Then, according to preset laser parameters, the controller controls the nanosecond laser galvanometer to scan the surface of the titanium chopstick tip, thereby achieving a hardening treatment on the surface of the titanium chopstick tip.

[0072] In one implementation, nanosecond lasers can utilize the high energy characteristics of lasers to cause physical or chemical changes in the surface material of titanium chopsticks, generating a dense oxide layer, thereby improving its hardness and other properties.

[0073] In one implementation, a nanosecond laser galvanometer is a device capable of rapidly changing the direction of a laser beam. The nanosecond laser galvanometer consists of a galvanometer motor and reflecting mirrors. By controlling the rotation of the galvanometer motor, the nanosecond laser galvanometer changes the angle of the reflecting mirrors, thereby achieving laser beam scanning.

[0074] In one implementation, the laser parameters may include laser power, pulse width, scanning speed, and other parameters. The settings of these parameters directly affect the laser's treatment effect on the surface of the titanium chopstick tip; different parameter combinations can achieve different degrees of hardening. Optionally, the laser parameters in this application can achieve a narrow linewidth, slow scanning method, resulting in stable and effective hardening of the titanium chopstick tip surface.

[0075] In one implementation, after acquiring the position of the titanium chopstick tip, the controller can use sensors to detect the reflection of laser light on the surface of the titanium chopstick tip, and calculate the target position of the nanosecond laser galvanometer when its focal point is aligned with the titanium chopstick tip. Then, the computer device can adjust the nanosecond laser galvanometer to this target position. Alternatively, the position and angle of the galvanometer can be adjusted manually.

[0076] In one implementation, at the initial moment, the position of the titanium chopstick tip aligned with the focal position of the nanosecond laser galvanometer can be the top or bottom of the titanium chopstick tip of the outermost chopstick among at least one chopstick.

[0077] For example, the focal point of the nanosecond laser galvanometer can be aligned with the top of the titanium chopstick tip of the leftmost chopstick. This top is the highest point of the titanium chopstick tip above the water surface.

[0078] For example, the focal point of the nanosecond laser galvanometer can be aligned with the bottom of the titanium chopstick tip of the leftmost chopstick. This bottom can be the lowest point of the titanium chopstick tip protruding above the water surface, that is, the position closest to the water surface.

[0079] In one implementation, the controller can control a nanosecond laser galvanometer to scan the surface of the titanium chopstick tip according to a scanning trajectory. Optionally, this scanning trajectory can be programmed by a computer to set the scanning path. For example, the scanning path can be a linear scan, a helical scan, etc.

[0080] In one implementation, when the clamp only clamps one chopstick at a time, the controller can use a spiral scanning method to scan the titanium chopstick head.

[0081] In another implementation, when the clamp can simultaneously hold multiple chopsticks, the controller can use linear scanning to synchronously scan the titanium tips of these chopsticks. Simultaneously, to ensure scanning uniformity, the controller can also control the clamp to rotate, causing each chopstick to rotate during the scanning process, ensuring that the nanosecond laser galvanometer can uniformly scan the entire titanium chopstick tip.

[0082] S103. The ceramic plate in the control test assembly is passed over the hardened titanium chopstick tip, and scratches are detected on the ceramic plate. If no scratches are detected, the fixing clamp is released to allow the chopstick to sink to the bottom of the heat-conducting liquid and enter the storage area set at the bottom of the receiving tank.

[0083] For example, after the surface of the titanium chopsticks has been hardened, the controller can control a ceramic plate in the test assembly to slide across the hardened surface of the titanium chopsticks. The controller can then detect whether any scratches appear on the ceramic plate. If no scratches are detected, it indicates that the surface hardening effect of the titanium chopsticks is good and meets the expected requirements. At this point, the controller releases the clamp, allowing the chopsticks to sink to the bottom of the heat-conducting liquid under gravity and enter the storage area located at the bottom of the receiving tank.

[0084] In one implementation, the testing component is a device for testing product performance. Optionally, the testing component may consist of a robotic arm, a ceramic plate, and testing equipment.

[0085] In one implementation, the ceramic sheet used in this application can be a white ceramic sheet. This white ceramic sheet has high hardness and good color rendering properties, and can leave obvious scratches when the titanium chopstick tip is not hard enough, thereby enabling the determination of whether the titanium chopstick tip's hardness is up to standard.

[0086] In one implementation, the detection device can be a vision sensor, such as a camera. This device acquires an image of the ceramic sheet and then identifies whether the operation resulted in scratches. Alternatively, the detection device can be an optical inspection instrument that uses optical principles to scan and analyze the surface of the ceramic sheet to determine if scratches exist.

[0087] In one implementation, the robotic arm can be a mechanical transmission device that controls the ceramic disc to slide across the surface of the titanium chopstick tip. The robotic arm can be used to fix the ceramic disc, move it to the corresponding position on the titanium chopstick tip, and control the ceramic disc to move along a preset trajectory. Optionally, this preset trajectory is typically a linear motion.

[0088] In one implementation, the storage area is a space specifically designed at the bottom of the receiving tank for storing qualified chopsticks. Optionally, this storage area can be isolated from the receiving tank. After isolation, the heat-conducting liquid in the storage area can be drained, allowing the chopsticks in the storage area to be removed or transferred to subsequent processes.

[0089] In this embodiment, by using a clamp to fix the chopsticks and injecting a heat-conducting liquid, adjusting the nanosecond laser galvanometer to focus on the titanium chopstick tip, and performing scanning hardening, controlling the ceramic sheet to pass over the hardened titanium chopstick tip, and detecting the scratches, the hardening efficiency of the titanium chopstick tip is improved.

[0090] In one example, the laser parameters in step S102 above may include at least one of power, scan linewidth, and scan speed. The power is 25 to 35 watts. Preferably, the power can be 30 watts. The scan linewidth is 0.03 to 0.06 mm. Preferably, the scan linewidth can be 0.04 mm. The scan speed is 300 to 350 mm per second. Preferably, the scan speed can be 320 mm per second.

[0091] In this example, by setting the laser parameters, the nanosecond laser galvanometer is used to perform surface hardening treatment on the titanium chopstick tip using a narrow linewidth slow scanning method.

[0092] In one example, when the ceramic sheet is small, only large enough to cover one titanium chopstick tip, the controller can use the ceramic sheet to test at least one titanium chopstick tip fixed to the clamp one by one. In this case, step S103 above, controlling the ceramic sheet in the testing assembly to slide across the hardened titanium chopstick tip, includes:

[0093] S1031, The titanium chopsticks being tested are raised to a preset height by using a fixing clamp.

[0094] For example, the controller can determine the testing order of each chopstick based on the spatial position of the clamp that holds each chopstick. After determining the chopstick to be tested, the controller can control the clamp that holds the chopstick to raise it to a preset height, thereby raising the titanium chopstick head.

[0095] In one implementation, a clamp is used to secure a chopstick. This clamp may have a lifting mechanism. A controller can control the lifting mechanism of the clamp to raise the chopstick fixed to it. Optionally, since the surface of the titanium chopstick tip has already been hardened, it is not necessary to ensure that the interface between the titanium chopstick tip and the body remains at the surface of the heat-conducting liquid.

[0096] In one implementation, the preset height is a pre-determined value based on testing requirements and experimental design. This preset height is typically small, intended only to ensure that the titanium chopstick tip being tested is higher than other titanium chopstick tips. This creates suitable space and conditions for subsequent interaction tests between the ceramic plate and the titanium chopstick tip, ensuring that the ceramic plate can individually contact the titanium chopstick tip being tested, thereby improving the accuracy and stability of the testing process.

[0097] S1032. After the ceramic plate is moved above the titanium chopstick head and the interaction force between the ceramic plate and the titanium chopstick head reaches the preset force, the ceramic plate is controlled to move according to the preset trajectory.

[0098] For example, the controller can first move the ceramic plate to a position directly above the titanium chopstick tip. The controller can obtain the interaction force between the ceramic plate and the titanium chopstick tip through the robotic arm in the testing component. After the interaction force reaches a preset value, the controller can control the ceramic plate to move along a preset trajectory.

[0099] In one implementation, the interaction force refers to the force generated between the ceramic sheet and the titanium chopstick tip during contact. If the interaction force is small, insufficient friction during sliding may prevent the formation of scratches, thus affecting the accuracy of the test.

[0100] In one implementation, the controller can detect the interaction force using a force sensor mounted on the test component. Alternatively, the controller can also detect the interaction force using a force sensor mounted on the clamp.

[0101] In one implementation, the preset trajectory is a pre-planned path for the ceramic sheet to move according to test requirements. Typically, this preset trajectory can be a straight line. Optionally, the preset trajectory may also include information such as moving distance and moving speed.

[0102] In this example, by controlling the position of the fixed clamp on the titanium chopstick head and precisely controlling the ceramic sheet to move along a preset trajectory after the interaction force between the ceramic sheet and the titanium chopstick head reaches a preset force, the hardening effect of the hardened titanium chopstick head can be tested one by one, thus improving the accuracy of the test.

[0103] In one implementation, if the clamp only secures one chopstick within the receiving slot, the controller does not need to control the clamp securing the chopstick to rise. Furthermore, the controller can directly control the robotic arm of the testing component to move the ceramic plate to the titanium chopstick tip position to complete the test.

[0104] In one example, after step S1032 above, the controller can further detect scratches on the ceramic sheet using a detection device and perform subsequent processing. This subsequent processing includes:

[0105] S1033. If scratches are detected on the ceramic disc, replace it with a new ceramic disc. Otherwise, if no scratches are detected on the ceramic disc, use the ceramic disc to test the next titanium chopstick tip.

[0106] For example, the controller can perform detection and analysis on the surface of the ceramic disc after the disc has slid across the titanium chopstick tip. This detection and analysis can detect scratches on the ceramic disc. Based on the detection results of these scratches, the controller can determine whether a new ceramic disc needs to be replaced.

[0107] In one implementation, if the controller does not detect a new scratch, it can use the ceramic plate to continue testing the next titanium chopstick tip. Otherwise, if the controller detects a new scratch, it can replace the ceramic plate to ensure the detection effect.

[0108] In one implementation, if the controller does not detect a new scratch, it can continue testing the next titanium chopstick tip using the current preset trajectory and the ceramic plate. Otherwise, if the controller detects a new scratch, to ensure detection effectiveness, it first determines whether there is a usable area on the surface of the ceramic plate. If a usable area exists, the controller adjusts the preset trajectory based on that area, allowing the next titanium chopstick tip to be tested on that usable area. If there is no usable area on the ceramic plate, the controller can replace it with a new ceramic plate.

[0109] In one implementation, the available area can be a scratch-free area on the surface of the ceramic sheet that is larger than or equal to a preset shape.

[0110] In one implementation, the scratch detection can be determined using an image recognition algorithm. The determination of the usable area can also be accomplished using an image recognition algorithm.

[0111] In one implementation, the controller can move the robotic arm of the test component to the ceramic sheet recycling area and then release the ceramic sheet, allowing it to enter the recycling area. Furthermore, the controller can control the robotic arm to grasp a new ceramic sheet, thus replacing it with a new one.

[0112] In this example, by detecting scratches on the ceramic plate and determining whether the ceramic plate needs to be replaced, the accuracy and reliability of the test are ensured.

[0113] In one example, when the ceramic plate is large and has the size to cover all the titanium chopsticks fixed in the clamp of the hardening device, the controller can use the ceramic plate to test all the titanium chopsticks fixed in the clamp simultaneously. In step S103 above, controlling the ceramic plate in the testing assembly to slide across the hardened titanium chopsticks includes:

[0114] S1034. Control the ceramic disc to move above all the titanium chopstick tips.

[0115] For example, the controller can use the robotic arm of the test component to move the ceramic plate to the area directly above all the titanium chopsticks to be tested.

[0116] In one implementation, the ceramic sheet located directly above the titanium chopstick head can be perpendicular to the titanium chopstick head.

[0117] In one implementation, the height of the ceramic plate located directly above the titanium chopstick head can be determined based on the height of the titanium chopstick head. That is, the height of the ceramic plate is precisely the height at which it contacts the titanium chopstick head. Optionally, when multiple titanium chopstick heads have different heights, the height of the ceramic plate is precisely the position where it contacts the tallest titanium chopstick head.

[0118] S1035. Move the fixing clamp of each chopstick upward so that the interaction force between the chopstick and the ceramic piece reaches the preset force.

[0119] For example, the controller sequentially controls the fixed clamp corresponding to each chopstick to move the chopstick upwards. During the movement, the fixed clamp can detect the interaction force between the chopstick and the ceramic plate. The controller can stop moving upwards when the interaction force between the chopstick and the ceramic plate reaches a preset force.

[0120] In one implementation, the controller can ensure that the force exerted between each titanium chopstick tip and the ceramic plate meets the interaction force required for hardness testing by controlling the movement of the fixing clamp. This setting avoids the problem of inaccurate testing due to insufficient interaction force between the titanium chopstick tip and the ceramic plate. Furthermore, by individually controlling each chopstick, this setting ensures the reliability of the batch testing results even when there are differences between different chopsticks.

[0121] S1036. Move the ceramic piece according to the preset trajectory.

[0122] For example, the controller precisely controls the movement of the ceramic disc according to a pre-set trajectory, so that the titanium chopstick tip slides across the ceramic disc.

[0123] In one implementation, the controller can determine which chopsticks meet the requirements and which do not by corresponding to each sliding position and the position of the titanium chopstick head in the test.

[0124] In this example, by moving the ceramic plate above all the titanium chopsticks, then raising the fixing clamp to ensure the interaction force between each chopstick and the ceramic plate reaches a preset force, and moving the ceramic plate along a preset trajectory, a method for batch testing the surface hardening performance of titanium chopsticks is achieved, thus improving testing efficiency. Furthermore, by raising each chopstick, the testing accuracy of each chopstick is ensured.

[0125] In one example, the controller can also control the subsequent processing of the titanium chopstick tip based on the scratches. This process may include:

[0126] S104. If a scratch is detected, based on the laser parameters, control the nanosecond laser galvanometer to scan the surface of the titanium chopstick tip again to harden the surface. Then, control the ceramic plate in the test assembly to slide across the hardened titanium chopstick tip to detect scratches on the ceramic plate.

[0127] For example, the controller can acquire the scratch detection results on the surface of the ceramic sheet. If a scratch is detected, it indicates that the surface hardness of the titanium chopstick tip is insufficient. At this time, the controller will precisely control the nanosecond laser galvanometer to scan the surface of the titanium chopstick tip again according to the preset laser parameters, and perform a hardening treatment. After the hardening treatment is completed, the controller controls the ceramic sheet in the test component to slide across the hardened surface of the titanium chopstick tip, and detects again whether scratches appear on the ceramic sheet, thereby determining whether the surface performance of the titanium chopstick tip after the second hardening treatment meets the requirements.

[0128] In one implementation, if the controller detects a new scratch, it can determine that the hardening process for that chopstick has failed. In this case, the controller can lower the chopstick back to its original height using a clamp and wait for all chopsticks to complete the test before attempting the hardening process again.

[0129] In one implementation, the controller adjusts the laser parameters based on pre-set parameters to generate laser parameters that better suit the needs of the titanium chopstick tip. Then, the controller uses the adjusted laser parameters to control the nanosecond laser galvanometer to scan the surface of the titanium chopstick tip again for hardening.

[0130] S105. Repeat the above process until no scratches are detected on the ceramic sheet.

[0131] For example, the controller will repeatedly execute the entire process in S104 above until no new scratches are detected on the ceramic plate. At this point, the controller can determine that the chopsticks have been successfully hardened. Then, the controller can release the retaining clamp to allow the chopsticks to sink to the bottom of the heat-conducting liquid and enter the storage area located at the bottom of the receiving tank.

[0132] In one implementation, if the number of iterations in step S104 reaches a maximum threshold, the controller can terminate the hardening process for the chopstick. Simultaneously, the controller can place the chopstick in the abnormal chopstick storage area.

[0133] In this example, by repeatedly performing the hardening and detection operations on the surface of the titanium chopsticks until the titanium chopsticks are hardened, the surface hardness of the titanium chopsticks is improved, thereby increasing the yield rate.

[0134] In one example, the laser parameters may include at least one of power, scan linewidth, and scan speed. In step S104 above, before the controller re-controlles the nanosecond laser galvanometer to scan the titanium chopstick surface, adjustments can be made to the existing laser parameters, including:

[0135] S1041. Increase power. Decrease scan line width. Decrease scan speed.

[0136] For example, the controller can adjust the laser parameters based on existing laser parameters before determining that the surface of the titanium chopstick tip needs to be hardened again. Specifically, the controller can increase the power and decrease the scan linewidth and scan speed.

[0137] In one implementation, since the existing laser parameters are used to harden the surface of the titanium chopsticks, the effect is not satisfactory. Therefore, in order to ensure that the hardening can achieve the expected effect, the controller can adjust the laser parameters to make them more suitable for the requirements.

[0138] In one implementation, power refers to the amount of energy output by the laser device.

[0139] In one implementation, the controller can increase the energy output of the laser by increasing the power, so that the surface of the titanium chopstick tip absorbs more heat per unit time, thereby promoting more complete physical and chemical changes and improving the hardening effect.

[0140] In one implementation, the scan linewidth refers to the width covered by the laser beam when scanning the surface of the titanium chopstick tip.

[0141] In one implementation, the controller can reduce the scan linewidth to allow the laser energy to be applied more concentratedly to a local area on the surface of the titanium chopstick tip, thereby enhancing the degree of local hardening.

[0142] In one implementation, the scanning speed refers to the speed at which the laser beam moves across the surface of the titanium chopstick tip.

[0143] In one implementation, the controller can increase the dwell time of the laser on each area of ​​the titanium chopstick tip by reducing the scanning speed, thereby enhancing the local hardening degree.

[0144] In one implementation, the controller can pre-store the adjusted power, the adjusted scan line width, or the adjusted scan speed. Once the controller determines that it needs to adjust the power, scan line width, or scan speed, it can directly obtain the pre-stored adjusted power, scan line width, or scan speed.

[0145] In one implementation, the controller can pre-store the power increase step size, the scan linewidth decrease step size, or the scan speed decrease step size. After determining that a power increase is needed, the controller can add the power increase step size to the current power to obtain the increased power. Alternatively, after determining that a scan linewidth decrease is needed, the controller can subtract the scan linewidth decrease step size from the current scan linewidth to obtain the decreased scan linewidth. Or, after determining that a scan speed decrease is needed, the controller can subtract the scan speed decrease step size from the current scan speed to obtain the decreased scan speed.

[0146] In one implementation, the controller may pre-store power adjustment curves, scan line width adjustment curves, or scan speed adjustment curves. After determining that the power needs to be increased, the scan line width needs to be decreased, or the scan speed needs to be decreased, the controller can obtain the next value from the corresponding adjustment curve and use that value as the adjusted power, scan line width, or scan speed.

[0147] S1042. Scan the surface of the titanium chopstick tip again using the adjusted nanosecond laser galvanometer.

[0148] For example, after adjusting the laser parameters, the controller will control the nanosecond laser galvanometer to scan the surface of the titanium chopstick tip again using the adjusted parameters, thereby achieving the hardening treatment of the titanium chopstick tip surface.

[0149] In this example, by optimizing the laser parameters by increasing the power, decreasing the scan linewidth, and decreasing the scan speed, and then using the adjusted laser parameters to control the nanosecond laser galvanometer to scan the surface of the titanium chopstick tip again, the effectiveness of the laser parameters is improved, thereby enhancing the surface hardening effect of the titanium chopstick tip.

[0150] Figure 3 A flowchart of a laser surface hardening method for titanium chopsticks provided in this application embodiment is shown below. Figure 1 and Figure 2 Based on the illustrated embodiments, as Figure 3 As shown, with the controller as the execution subject, the process includes the following steps:

[0151] S301. The design includes a clamp to ensure that the chopsticks are upright.

[0152] In one implementation, the clamp that keeps the chopsticks vertical can be used to fix the chopsticks in place by means of a wire clamp bolt.

[0153] S302. The titanium chopstick tip is placed in a heat-conducting liquid. Optionally, the heat-conducting liquid can be a cooling liquid.

[0154] In one implementation, the heat-conducting liquid can be pure water.

[0155] In one implementation, the container is filled with pure water, ensuring that only the hardened titanium chopstick tips protrude above the water surface.

[0156] S303. Use a wide-pulse laser galvanometer to perform surface hardening treatment on the titanium chopstick tip.

[0157] In one implementation, the wide-pulse laser galvanometer is specifically a nanosecond laser galvanometer.

[0158] In one implementation, a narrow-linewidth slow-sweep method can be used to perform surface hardening treatment on the titanium chopstick tip.

[0159] In one implementation, the controller can adjust the titanium chopstick tip that needs to be hardened to the focal point of the nanosecond laser galvanometer system, with the power of the nanosecond laser galvanometer system adjusted to 30 watts, the scanning line width to 0.04 mm, and the scanning speed to 320 mm per second.

[0160] S304. Inspect the surface hardening degree of titanium chopsticks. Repeat the hardening treatment for titanium chopsticks that are not hardened enough.

[0161] In one implementation, the controller can choose whether to inspect the surface hardening degree of the titanium chopstick tip by scratching the ceramic. If scratches appear, it indicates that the titanium chopstick tip is not hardened enough. In this case, the controller can repeat the hardening process on the insufficiently hardened titanium chopstick tip.

[0162] In one implementation, if no scratches appear on the ceramic piece after repeated and forceful scraping, it indicates that the titanium chopstick tip has met the hardening requirements.

[0163] In this embodiment, by placing chopsticks vertically in water with the titanium chopstick tips exposed above the water surface, laser hardening of the titanium chopstick tips is performed using a wide-pulse laser galvanometer. The completion of hardening is determined by scratching the surface of a ceramic sheet, thus improving the hardening efficiency and reliability of the titanium chopstick tips. Furthermore, by placing the chopsticks in water, heat conduction is achieved during the laser hardening process, significantly eliminating thermal parasitic streaks.

[0164] Compared to existing technologies such as anodizing and high-temperature oxidation, the nanosecond laser surface hardening treatment used in this application has a significant hardening effect. For example... Figure 4 The image shows scratches left on a ceramic sheet by a titanium chopstick tip after laser oxidation, anodizing, and high-temperature oxidation treatments, respectively. Figure 4 (a) After the surface of the titanium chopstick tip is hardened by laser oxidation using the method of this application, no marks are left on the ceramic sheet during the process of the titanium chopstick tip scraping against the ceramic sheet. Figure 4 (b) After the titanium chopstick tip was hardened by anodizing, it left a mark on the ceramic sheet during the scraping process. Figure 4 (c) The marks left on the ceramic sheet by the titanium chopstick tip after it has been hardened by high-temperature oxidation, during the scraping process. Therefore, it is evident from the comparison that the laser surface hardening method of this application achieves a better hardening effect on the surface of the titanium chopstick tip. Furthermore, the heating effect of high-temperature oxidation is superior to that of anodizing.

[0167] The laser module 502 is used to adjust the focus of the nanosecond laser galvanometer in the laser assembly to align with the titanium chopstick tip, and to control the nanosecond laser galvanometer to scan the surface of the titanium chopstick tip according to the preset laser parameters, thereby hardening the surface of the titanium chopstick tip.

[0168] The detection module 503 is used to control the ceramic plate in the test component to slide across the hardened titanium chopstick tip and detect the scratches on the ceramic plate; if no scratches are detected, the fixing clamp is released so that the chopstick sinks to the bottom of the heat-conducting liquid and enters the storage area set at the bottom of the receiving tank.

[0169] In one example, the ceramic sheet is the size of one titanium chopstick tip; detection module 503 is used for:

[0170] The titanium chopstick tip being tested is raised to a preset height using a fixing clamp.

[0171] Once the ceramic disc is moved above the titanium chopstick head and the interaction force between the ceramic disc and the titanium chopstick head reaches a preset force, the ceramic disc is controlled to move according to a preset trajectory.

[0172] In one example, the detection module 503 is used for:

[0173] If scratches are detected on the ceramic chip, replace it with a new ceramic chip;

[0174] Otherwise, if no scratches are detected on the ceramic plate, the ceramic plate is used to test the next titanium chopstick tip.

[0175] In one example, the ceramic sheet has the size of a retaining clip covering the entire titanium chopstick tip of the hardening device; detection module 503 is used for:

[0176] Control the ceramic disc to move above all the titanium chopstick tips;

[0177] Move the clamps holding each chopstick upwards so that the interaction force between the chopsticks and the ceramic piece reaches the preset force;

[0178] The ceramic piece moves according to a preset trajectory.

[0181] Repeat the above process until no scratches are detected on the ceramic plate.

[0182] In one example, the laser parameters include at least one of power, scan linewidth, and scan speed; laser module 502 is used for:

[0183] Increase power; decrease scan line width and / or scan speed;

[0184] The surface of the titanium chopstick tip was scanned again using an adjusted nanosecond laser galvanometer.

[0185] In one example, the laser parameters include at least one of power, scan linewidth, and scan speed;

[0186] The power is 25 to 35 watts, the scan line width is 0.03 to 0.06 mm, and the scan speed is 300 to 350 mm per second.
