Description

Technical Field

[0001] This utility model belongs to the field of adhesion testing technology, specifically relating to a multi-axis adhesion testing device. Background Technology

[0002] Adhesion testing is an important method for evaluating the performance of coatings or films on material surfaces, and it has wide applications in industrial production and scientific research. Traditional adhesion testing devices typically employ a single clamping method and a simple linear motion mechanism, which is insufficient to meet the demands for efficient and high-precision testing. For example, in existing technologies, most adhesion testing equipment only supports testing a single sample, and deviations are prone to occur during clamping and positioning, affecting the accuracy of the test results. Furthermore, traditional equipment often lacks efficient cleaning functions, requiring manual removal of residues after testing, increasing operation time and costs.

[0003] Chinese Patent CN213456609U discloses an ink adhesion testing machine, including a support frame, a transmission device, a control component, and a motor. The support frame includes a base plate, a top plate, and multiple columns. An anti-slip plate for supporting the test piece is located on the left side of the base plate, while the control component and motor are placed on the right side. The transmission device includes a disc, a connecting rod, a guide rail, a sliding block, a pull rod, and a flat block. The lower end of the disc is fixedly connected to the end of a rotating shaft provided with the motor. One end of the connecting rod is connected to the outer side of the disc, and the other end of the connecting rod is connected to the sliding block. The sliding block engages with the guide rail on the top plate. A vertical through hole is provided in the middle of the sliding block, which slides with the pull rod. The bottom of the pull rod is fixedly connected to the flat block, which has a cleaning section at its bottom. The bottom of the cleaning section fits snugly with the anti-slip plate and is used to wipe the ink off the surface of the test piece. This device only supports testing a single test piece and cannot simultaneously scratch or test multiple test plates, making it unsuitable for multi-station or batch testing needs. Therefore, it is imperative for those skilled in the art to solve the aforementioned technical problems. Utility Model Content

[0004] The technical problem this invention aims to solve is that, in the prior art, the battery pack positioning adjustment mechanism involves the coordinated use of multiple slide rails and positioning components, making the adjustment process more complex and time-consuming for operators compared to simple bolt fixing.

[0005] To solve the above-mentioned technical problems, the technical solutions adopted by this utility model are as follows:

[0006] A multi-axis adhesion testing device includes a base, grippers, support arms, slide rails, a scrubbing head, a blowing device, and a drive assembly. The base has at least three grippers, and support arms are located on both sides of the base. The blowing device is mounted on the base. The drive assembly includes a drive motor and a displacement screw. The displacement screw includes an X-axis screw, a Y-axis screw, and a Z-axis screw. The Y-axis screw is mounted at the tail end of the base, the X-axis screw is mounted on both sides of the base, the Z-axis screw is mounted between the support arms, and the scrubbing head is mounted at the bottom of the Z-axis screw.

[0007] By employing the above technical solution, and driven by lead screws along the X, Y, and Z axes, precise testing of the adhesion force on the sample surface in different directions can be achieved. This allows the device to adapt to various complex testing needs, including but not limited to evaluating the adhesion performance of coatings, adhesives, and other materials at different angles and directions. Position adjustment using the displacement lead screw provides very high positioning accuracy, ensuring that each test is conducted under identical conditions, thereby improving the repeatability and reliability of test results. The gripper design allows for the fixing of samples of different shapes and sizes, increasing the device's application range. Simultaneously, the purging device cleans the sample surface before and after testing, reducing the influence of external factors on the test results and ensuring data accuracy. The combined use of the drive motor and displacement lead screw achieves an automated testing process, reducing manual intervention, improving work efficiency, and lowering the technical requirements for operators.

[0008] Furthermore, a rotary motor is provided at the bottom of the gripper, and a vortex-type adjustable chuck is provided inside the gripper. The power output end of the rotary motor is connected to a connecting rod at the bottom of the gripper, and the connecting rod is fitted onto the vortex-type adjustable chuck.

[0009] By adopting the above technical solution, and by setting a rotary motor at the bottom of the gripper and configuring a vortex-type adjustable chuck inside the gripper, samples of different shapes, sizes, and surface curvatures can be fixed. This design allows the gripper to adjust the clamping force and angle according to the specific conditions of the sample, thereby increasing the adaptability of the equipment to various samples. The rotary motor drives the connecting rod to rotate the vortex-type adjustable chuck, enabling the gripper to precisely adjust its position and angle, ensuring that the sample is firmly and correctly fixed, reducing measurement errors caused by improper sample fixing, and thus improving the accuracy of test results. This design supports arbitrary angle rotation adjustment of the sample, which is particularly important for applications that require evaluation of material adhesion at specific angles. For example, when evaluating the adhesion of coatings with certain special structures or morphologies, it can more accurately simulate actual usage conditions. Using an automated control system, different clamping modes and rotation parameters can be preset through software, enabling one-click automatic clamping and positioning of samples. This not only reduces the difficulty of operation but also improves work efficiency and reduces the possibility of human error.

[0010] Furthermore, the gripper is provided with four positioning pins. When the connecting rod rotates in the forward direction, it drives the positioning pins to move outward along the worm-shaped adjustable chuck. When the connecting rod rotates in the reverse direction, it drives the positioning pins to move inward along the worm-shaped adjustable chuck.

[0011] By adopting the above technical solution, the four positioning posts can provide a more stable and balanced clamping force, ensuring that the sample is firmly fixed. Compared with single-point or two-point contact, multi-point contact can more effectively disperse pressure and avoid local damage to the sample. The forward and reverse rotation of the connecting rod drives the positioning posts to move along the vortex-shaped adjustable chuck, allowing users to precisely adjust the opening size of the jaws to accommodate samples of different sizes. This mechanism allows the jaws to quickly adapt to samples of various shapes and sizes, effectively clamping round, square, or other irregularly shaped objects. This greatly expands the application range of the equipment, improves its versatility and practicality, and reduces the complexity and time consumption of manual adjustment, thus improving work efficiency, because complex clamping tasks can be achieved through simple rotational movements.

[0012] Furthermore, the X-axis lead screw passes through the base, and the X-axis lead screw is connected to the support arm through a connecting rod. Slide rods are also provided on both sides of the base, and the support arm is fitted onto the slide rods.

[0013] By adopting the above technical solution, the X-axis lead screw can provide precise linear movement, ensuring accurate positioning of the support arm in the X-axis direction. This design is particularly important for applications requiring high-precision operation (such as precision machining and measuring equipment). The support arm, fitted onto the slide bar, effectively prevents deflection or wobbling during movement, increasing the stability and rigidity of the entire system. This helps maintain consistency and reliability during long-term operation. The slide bar design reduces the direct contact area between the support arm and the base, thereby reducing friction and wear. This translates to a longer service life and lower maintenance costs. The modular design allows for easy disassembly and replacement of the X-axis lead screw, slide bar, and related components, facilitating maintenance and repair. Furthermore, this design also simplifies initial installation and commissioning.

[0014] Furthermore, the purging device includes an air pump, a hose, and a nozzle. The air pump is bolted to the base, and the air outlet of the air pump is connected to the nozzle via the hose.

[0015] Furthermore, a mounting bracket is provided between the support arms, the Z-axis lead screw and the drive motor are mounted on the mounting bracket, and the mounting bracket is fitted onto the Y-axis lead screw.

[0016] By adopting the above technical solution, mounting the Z-axis assembly on a stable mounting bracket instead of directly fixing it to the support arm significantly improves the rigidity and stability of the entire system. This helps reduce vibration and misalignment, ensuring high-precision work execution. Since the mounting bracket can move along the Y-axis lead screw, users can quickly adjust the Z-axis position as needed to accommodate workpieces of different sizes or shapes. This design increases the versatility and flexibility of the equipment. By rationally arranging the positions of the lead screws and their related components, maximum functional configuration can be achieved within a limited space. For example, placing the Z-axis assembly between the support arms does not increase the overall footprint of the equipment while leaving sufficient operating space for other components. The presence of the mounting bracket helps distribute the force exerted by the Z-axis assembly on the support arm, reducing the risk of overloading a single component and thus extending the service life of the entire mechanical system. Integrating the Z-axis lead screw and drive motor onto a separate mounting bracket makes these critical components easily accessible and maintainable. If a part needs to be replaced or upgraded, it can be done relatively simply without causing significant disruption to the entire system.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model allows the equipment to make precise linear movements in the X, Y, and Z directions by setting a mounting bracket between the support arms and mounting the Z-axis lead screw and drive motor on it. This design achieves very high positioning accuracy and ensures the consistency and reliability of repeated positioning. This layout enables the machine to perform tasks in complex spaces, improving its applicability and technical capabilities.

[0019] 2. The design of the mounting bracket in this utility model not only provides additional support points, but also significantly enhances the stability and rigidity of the entire mechanical structure. Since the mounting bracket is directly connected to the support arm, it reduces vibration and displacement caused by high-speed movement or heavy load, helps to disperse the force, thereby reducing the overload risk of individual components and extending the overall service life of the equipment. By optimizing the selection of mounting bracket materials and geometry, the effects of thermal expansion and deformation can be further reduced, ensuring long-term stable performance.

[0020] 3. This utility model allows the Z-axis lead screw to be flexibly adjusted along the Y-axis lead screw. This means that users can quickly change the height and position of the working area according to actual needs, which is particularly useful for handling work objects of different sizes and shapes. Since the mounting bracket and its related components are modularly designed, they are easy to disassemble and replace, thus simplifying the maintenance process. At the same time, it is also convenient to upgrade the equipment according to technological progress or changes in production needs. These features together enhance the ease of operation and market competitiveness of the equipment. Attached Figure Description

[0029] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As can be seen, this utility model discloses a multi-axis adhesion testing device, including a base 1, grippers 2, support arms 11, slide rails 3, a scribing head 4, a purging device 5, and a drive assembly 6. The base 1 is a rectangular frame structure with slide rails 3 on its surface to support the sample to be tested. Support arms 11 are symmetrically installed on both sides, and the support arms 11 are slidably connected to the base 1 through slide rods 12, enabling movement along the Y-axis. A Y-axis lead screw 63 is fixedly installed at the tail end of the base 1, and X-axis lead screws 62 are installed on both sides. A Z-axis lead screw 64 is provided between the support arms 11, and the scribing head 4 is installed at the bottom of the Z-axis lead screw 64. Multi-axis linkage control is achieved through the drive assembly 6. The base 1 is equipped with at least three grippers 2. Each gripper 2 has a rotary motor 23 installed at its bottom, and its power output end is connected to a connecting rod 22. The connecting rod 22 is fitted into a worm-shaped adjustable chuck 24. The surface of the chuck 24 is provided with a spiral groove. The gripper 2 has four positioning posts 21 inside, and the ends of the positioning posts 21 are embedded in the spiral grooves. When the rotary motor 23 drives the connecting rod 22 in the forward direction, the worm-shaped adjustable chuck 24 rotates and pushes the positioning posts 21 to move radially outward through the spiral grooves, and the grippers 2 open to release the sample. When driven in the reverse direction, the positioning posts 21 retract inward along the spiral grooves, and the grippers 2 close to clamp the sample, adapting to samples of different sizes and ensuring clamping stability. The drive assembly 6 includes a drive motor 61, an X-axis lead screw 62, a Y-axis lead screw 63, and a Z-axis lead screw 64. The Y-axis lead screw 63 passes through the base 1, and the drive motor 61 drives it to rotate via a gear set, causing the support arm 11 to move along the slide bar 12 in the Y-axis direction. The X-axis lead screw 62 is symmetrically installed on both sides of the base 1 and is connected to the drive motor 61 via a synchronous belt, driving the support arm 11 to move along the slide rail 3 in the X-axis direction. A mounting bracket 13 is provided between the support arms 11, and the Z-axis lead screw 64 is vertically fixed on the mounting bracket 13. The drive motor 61 drives the Z-axis lead screw 64 to rotate, causing the scratching head 4 to rise and fall vertically to precisely control the scratch depth. The blowing device 5 includes an air pump 51, a hose 52, and a nozzle 53. The air pump 51 is fixed to one side of the base 1 by bolts, and its air outlet is connected to the nozzle 53 via the hose 52. The nozzle 53 faces the working area of ​​the scratching head 4. During testing, the air pump 51 is activated, and the airflow is continuously sprayed to remove the debris generated by the scratches, ensuring the accuracy of the test.

[0030] The actual testing process is as follows: after the sample is clamped by the gripper 2, the drive component 6 controls the scratching head 4 to perform scratching tests in conjunction with the X, Y, and Z axes according to the preset trajectory, and the nozzle 53 of the moving blowing device 5 removes the debris simultaneously.

[0031] Working principle: First, the sample to be tested is firmly fixed to the base 1 using the grippers 2. Each gripper 2 is equipped with a rotary motor 23, the power output of which is connected to a connecting rod 22, and the connecting rod 22 is fitted inside a worm-shaped adjustable chuck 24. When the rotary motor 23 drives in the forward direction, the worm-shaped adjustable chuck 24 rotates and pushes the positioning post 21 to move radially outward through the helical groove, causing the grippers 2 to open to release or adjust the sample position; when driven in the reverse direction, the positioning post 21 retracts inward along the helical groove, and the grippers 2 close to clamp the sample, ensuring that samples of different sizes can be firmly clamped. After the sample is clamped, the drive assembly 6 starts to work. The drive assembly 6 includes a drive motor 61, an X-axis lead screw 62, a Y-axis lead screw 63, and a Z-axis lead screw 64. These components work together to achieve precise movement of the scribing head 4 in three-dimensional space. The Y-axis lead screw 63, mounted at the tail end of the base, is responsible for this movement. The drive motor 61 drives the Y-axis lead screw 63 to rotate via a gear set, causing the support arm 11 to move along the slide bar 12 in the Y-axis direction. The X-axis lead screws 62 are symmetrically mounted on both sides of the base and connected to the drive motor 61 via a synchronous belt, thus driving the support arm 11 to move along the slide rail 3 in the X-axis direction. A mounting bracket 13 is provided between the support arms 11, and the Z-axis lead screw 64 is vertically fixed to the mounting bracket 13. The drive motor 61 drives the Z-axis lead screw 64 to rotate, causing the scribing head 4 to rise and fall vertically, precisely controlling the scratch depth. After clamping and adjusting the position of the sample, the scribing head 4 performs a scratch test on the sample surface according to a preset trajectory, with the X, Y, and Z axes working in tandem. Simultaneously, the purging device 5 is activated. The airflow generated by the air pump 51 is delivered to the nozzle 53 through the hose 52 and continuously sprayed towards the working area of ​​the scribing head 4, effectively removing debris generated during the scratching process and ensuring the accuracy of the test results is not affected.

[0032] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
