Description

Technical Field

[0001] The present invention relates to the technical field of hair button testing, and in particular to a hair button pressure deformation testing device and a testing method. Background Art

[0002] Button connectors are widely used in electronic devices, mechanical devices, and various precision instruments, primarily for mechanical connection, signal transmission, and structural support. Their performance is directly related to the stability and reliability of the entire device. In actual use, certain electronic products require the connector to withstand axial pressure. Because the material of a button connector typically exhibits a certain degree of elasticity and deformation, accurately evaluating its pressure-bearing deformation performance is crucial.

[0003] However, there is currently no testing device or method on the market for the pressure deformation performance of button connectors. This makes it impossible to fully reflect the actual stress state and deformation of button connectors under actual working conditions. This also makes it impossible to provide comprehensive and accurate data support for design optimization, quality control, and service life assessment of button connectors.

[0004] Therefore, there is an urgent need for a testing device and method that can simulate the actual operating conditions of the hair button connector and accurately measure its axial pressure deformation performance to meet its quality inspection and performance evaluation needs in modern industrial production. Summary of the Invention

[0005] In order to overcome the deficiencies in the background technology, the present invention discloses a device and method for testing the pressure deformation of a wool button.

[0006] In order to achieve the above-mentioned object of the invention, the present invention adopts the following technical solutions:

[0007] A device and method for testing the pressure deformation of a wool button, comprising:

[0008] A base having an installation cavity formed therein;

[0009] The rotating platform is rotatably connected to the top of the base, and a motor for driving the rotating platform to rotate according to a set angle is installed in the mounting cavity of the base;

[0011] The bottom of the glass tube is inserted into the positioning boss of the support base; a hair button is vertically placed in the glass tube; the ratio of the inner diameter of the glass tube to the diameter of the hair button is 3 to 5:1;

[0012] A pressurizing device, installed on the base, is used to apply a vertical load to the glass tube to compress it vertically;

[0013] The bracket is provided on one side of the rotating platform, and the bottom thereof is firmly connected to the base;

[0014] The CCD camera is mounted on a bracket and is used to take pictures of the hair buttons in the glass tube.

[0015] Preferably, the pressurizing device comprises:

[0016] The gantry is erected on the base;

[0017] The pressure rod is movable and runs through the top crossbeam of the gantry;

[0018] The driving device is installed on the gantry beam and is used to drive the pressure rod to move vertically;

[0019] The top of the thimble is rotatably connected to the pressure rod, and the bottom is movably inserted into the glass tube, which is used to vertically pressurize the hair button.

[0020] Preferably, the driving device is a screw-nut mechanism driven by a motor.

[0021] Preferably, it further comprises a shielding cover which is in a semicircular structure and is arranged on a side of the rotating platform away from the CCD camera.

[0022] Preferably, the shielding cover is a hollow structure, the inner side of which is a light-transmitting frosted surface, and a plurality of LED light sources are arranged in an array in the cavity of the shielding cover.

[0023] Preferably, one side of the shielding cover shell is rotatably connected to the pressurizing device.

[0024] Preferably, a limiting column for limiting the deflection angle of the shielding cover is provided on the top of the base.

[0025] Preferably, two top blocks are movably inserted into the glass tube, and the hair button is located between the two top blocks.

[0026] Preferably, the end of the top block corresponding to the wool button is in a conical cavity structure, and viscous grease is stored in the conical cavity structure.

[0027] The testing method using the hair button pressure deformation testing device includes the following steps:

[0028] S1. Place the hair button in the glass tube;

[0029] S2. Insert the glass tube vertically into the positioning boss of the support base so that the hair button remains vertical;

[0030] S3. Turn on the pressure device and apply vertical pressure to the wool button to compress it gradually. The maximum compression is 30% of the length of the wool button. Pause every 1% to 5% of the compression.

[0031] S4.

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. 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.

[0046] In the description of the present invention, it should be noted that the terms "upper" and "lower" etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the inventive product is usually placed when in use. These are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention.

[0047] In this application, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be interpreted broadly. For example, they may refer to fixed connection, detachable connection, or integration; they may refer to direct connection or indirect connection through an intermediate medium; they may refer to internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0048] Example 1:

[0049] Combined with attachment Figures 1 to 3 , a device and method for testing the pressure deformation of hair buttons, comprising a base 1, a rotating platform 2, a pressurizing device and a CCD camera 10. The base 1 serves as the basic component of the entire device, and a mounting cavity is designed inside the base 1 for accommodating other key components. The rotating platform 2 is mounted on the top of the base 1 by a rotating connection and can achieve intermittent rotation. A motor is installed in the mounting cavity of the base 1, and the motor is used to drive the rotating platform 2 to intermittently rotate according to a set angle, and pause for 1 to 2 seconds after each rotation to ensure the stability of the test process and the accuracy of data acquisition.

[0050] A support base 3, equipped with a positioning boss, is coaxially secured to the top of the rotating platform 2. A glass tube 4 is inserted into the positioning boss of the support base 3, and a hair button is placed vertically within the glass tube 4. To ensure that the rotating platform 2 drives the support base 3 and the glass tube 4 in synchronous rotation, a certain amount of friction is required between the glass tube 4 and the support base 3. This friction is designed to ensure that the hair button rotates synchronously with the glass tube 4 during testing, thus preventing deviations in test results due to relative motion.

[0051] The base 1 is also equipped with a pressure device, whose primary function is to apply a vertical load to the hair button inside the glass tube 4, compressing it vertically. This vertical compression causes the hair button to deform radially. To ensure that the glass tube 4 does not interfere with the hair button's deformation during testing, the ratio of the glass tube's inner diameter to the hair button's diameter is designed to be 3 to 5:1. This ratio, based on experimental data and theoretical analysis, effectively prevents the glass tube 4 from restricting the hair button's deformation, thereby ensuring the accuracy of the test results.

[0052] Furthermore, two top blocks 13 are movably inserted into the glass tube 4, with the hair button located between them. The top block 13 transmits pressure, and its design, adapted to the glass tube 4, ensures that the hair button is subjected to force along its axial direction. This design is crucial for improving test accuracy, as it ensures that the hair button maintains a stable axial position during force application, preventing deformation caused by lateral forces. The end of the top block 13 corresponding to the hair button is designed with a conical cavity structure, which stores a viscous grease. The diameter of a hair button is typically 0.2 to 1.2 mm, with an aspect ratio of 3 to 10:1. The viscous grease adheres to the hair button, facilitating its assembly within the glass tube 4. The grease also acts as a lubricant, automatically maintaining coaxiality with the top block 13 when pressure is applied. This design effectively reduces the difficulty of testing and improves test accuracy.

[0053] It should be noted that a certain contact friction force needs to be ensured between the top block 13 and the inner wall of the glass tube 4 to ensure that the glass tube 4 can drive the top block 13 to rotate synchronously and avoid relative rotation between the hair button and the glass tube 4 during the test.

[0054] A bracket 9 is fastened to one side of the base 1 corresponding to the rotating platform 2 , and a CCD camera 10 is mounted on the bracket 9 , the main function of which is to take pictures of the hair buttons in the glass tube 4 .

[0055] The testing process is carried out as follows:

[0056] S1. Place the wool button in the glass tube 4 and ensure that it is in a vertical position.

[0057] S2. Insert the glass tube 4 vertically onto the positioning boss of the support seat 3 to keep the hair button in a vertical state.

[0058] S3. Turn on the pressure device and apply vertical pressure to the button, gradually compressing it. The maximum compression is 30% of the button's length. During the compression process, pause every 1% to 5% of the button's length. This pause allows time for subsequent photography and quantitative analysis of the button's deformation under pressure.

[0059] S4. Every time the button is compressed by 1% to 5%, the rotating platform 2 is activated, causing the button to intermittently rotate at an angle of 1 to 3 degrees until it completes one full rotation. During the intervals between rotations, the CCD camera 10 is activated to photograph the button, and the images are grouped according to the amount of compression. This method can analyze the deformation characteristics and amount of the button during the gradual compression process, thereby providing guidance for the production and subsequent use of the button.

[0060] Example 2:

[0061] Combined with attachment Figures 1 to 2 The present invention provides a device and method for testing the pressure deformation of hair buttons, which mainly differs from the first embodiment in the specific structural design of the pressure device. On the basis of the first embodiment, the pressure device includes a gantry 5, a driving device 7 and a thimble 8. The gantry 5 is erected on the base 1, and its two legs are correspondingly and tightly connected to the top of the base 1 to form a stable support structure. The top crossbeam of the gantry 5 is provided with a through hole, and the pressure rod 6 is arranged at the position corresponding to the through hole and can move through the through hole of the crossbeam. A driving device 7 is installed on the crossbeam of the gantry 5, which is used to drive the pressure rod 6 to move vertically. The bottom of the pressure rod 6 is rotatably connected to the thimble 8, and the bottom of the thimble 8 is movably inserted into the glass tube 4 to apply vertical pressure to the hair button. Since the thimble 8 is rotatably connected to the pressure rod 6, when the rotating platform 2 rotates, the thimble 8 can rotate together with the glass tube 4, thereby effectively preventing the top block 13 from rotating relative to the glass tube 4. This design ensures the synchronous movement of the hair button and the glass tube 4 during the test, avoiding test errors caused by relative movement.

[0062] Specifically, the drive device 7 utilizes a motor-driven screw-nut mechanism. The nut of the screw-nut mechanism is fixed to the crossbeam of the gantry 5, and the screw and nut are threadedly connected. The output of the motor is connected to the screw drive. The motor drives the screw to rotate a certain angle, causing the screw to move axially a certain distance, thereby achieving quantitative compression of the hair button. This quantitative compression design ensures that the hair button is subjected to precise loads during testing, providing reliable data support for subsequent deformation analysis.

[0063] Example 3:

[0064] Combined with attachment Figures 4 to 6 The present invention provides a device and method for testing the deformation of hair buttons under pressure. Based on the first or second embodiment, the structural design of the device is further optimized. A semicircular shielding cover 11 is provided on the side of the rotating platform 2 facing away from the CCD camera 10. The main function of the shielding cover 11 is to provide a clean photographic environment for the CCD camera 10, preventing irrelevant content from being captured, thereby facilitating subsequent image analysis. This design can effectively improve image quality and analysis accuracy, providing better conditions for deformation detection of hair buttons.

[0065] Furthermore, the shielding cover 11 is a hollow structure with a light-transmitting frosted inner surface. This design prevents reflections, thereby preventing interference with the CCD camera 10's image capture. Multiple LED light sources are arrayed within the cavity of the shielding cover 11. During testing, the LED light sources can be activated to provide fill light, making the obtained image clearer. This fill light design effectively improves image contrast and clarity, further enhancing the accuracy of the test.

[0066] Furthermore, one side of the shielding cover 11 is rotatably connected to the pressurizing device. For example, the shielding cover 11 can be rotatably connected to one of the legs of the gantry 5. This rotatable connection design allows the shielding cover 11 to be deflected and opened when removing and placing the glass tube 4 and the hair button, facilitating their installation on the support base 3. After installation, the shielding cover 11 is deflected and closed, providing an optimal recording environment for the CCD camera 10. This deflectable design not only improves the device's operational convenience but also ensures the stability of the testing process.

[0067] Furthermore, the top of the base 1 is equipped with a limiting post 12 for limiting the deflection angle of the shield 11. When the shield 11 is closed, the limiting post 12 controls the position of the shield 11. This limiting design ensures that the shield 11 remains stable in the closed state, preventing it from shifting due to external forces, which could affect the shooting effect. This design makes operation more convenient and quick, while also improving the overall stability and reliability of the device.

[0068] The parts of the present invention that are not described in detail are prior art. It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and it is intended that all changes that fall within the meaning and scope of equivalent elements are included in the present invention.
