Description

Technical Field

[0001] The invention relates to the technical field of wear testing, and in particular to a button bite wear testing device and a testing method. Background Art

[0002] Buttons are a common accessory on clothing. They not only play a role in connection and decoration, but also affect the overall quality and user experience of clothing to a certain extent. Snap buttons are a widely used type of button, also known as press buttons. Snap buttons consist of two parts: a male button and a female button. The male button usually has a convex part, while the female button has a corresponding groove, and an elastic part is provided at the groove. When fastening, the convex part of the male button is inserted into the groove of the female button, and the elastic part of the female button generates friction and tension on the convex part, thereby maintaining the fastened state; when releasing the fastened state, the male button is pulled out of the female button by applying appropriate pulling force, overcoming its friction and tension, so that the convex part is separated from the groove, thereby achieving unfastening. In the process of continuous fastening and unfastening of the snap button, the male button and the female button will wear, which will affect the tightness of the fastening state, that is, affect the service life of the snap button. Therefore, it is necessary to test the bite wear of the snap button to evaluate its durability and reliability in long-term use.

[0003] When testing the bite wear of a snap button, the existing button bite wear test device usually aligns the raised part of the male button with the groove of the female button, and continuously performs the insertion and extraction movement to obtain the number of insertion and extraction times when the snap button is worn. However, in the actual use of the snap button, the raised part of the male button is not inserted vertically into the groove of the female button, but is inserted obliquely (such as the user presses the male button from one side to make it buckle); at the same time, when the male button is pulled out, the tension applied to the male button is not perpendicular to the axis of the groove (such as the user holds the clothing and applies tension to one side of the male button through the clothing). Therefore, when testing the bite wear of a snap button, the existing button bite wear test device has a large difference from the buckling and unbuttoning methods when the snap button is actually used, resulting in large errors in the test results. Therefore, a button bite wear test device and test method are proposed. Summary of the invention

[0038] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below 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 creative work are within the scope of protection of the present invention.

[0039] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0040] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0041] Embodiment 1:

[0042] Reference Figures 1 to 10The embodiment of the present invention provides a button bite wear test device, including a machine base 10, a button seat 20, a driving mechanism 30 and a deflection device 40. The button seat 20 is arranged at one end of the machine base 10, and includes a female buckle seat 21 and a male buckle seat 22. The female buckle seat 21 is provided with a female buckle mounting position; the male buckle seat 22 is provided with a male buckle mounting position. During the test, the female buckle is fixedly installed on the female buckle seat 21, and the male buckle is fixedly installed on the male buckle seat 22. The driving mechanism 30 is arranged at the other end of the machine base 10, and the driving end of the driving mechanism 30 can make linear reciprocating motion. The driving end of the driving mechanism 30 is connected to the male buckle seat 22 to drive the male buckle seat 22 to make linear reciprocating motion, so that the male buckle and the female buckle are repeatedly engaged and separated. The deflection device 40 includes a deflection shaft 41 connected to the female buckle seat 21 at one end and a first driving member 42. The deflection shaft 41 is rotatably connected to a base 43, the base 43 is fixedly connected to the inner side wall of the machine base 10, and the base 43 is rotatably connected to the deflection shaft 41. Optionally, the base 43 is arranged at the midpoint of the deflection shaft 41, that is, the two ends of the deflection shaft 41 swing around the base 43 with the same amplitude. The deflection shaft 41 is provided with a second driving member 44 at one end away from the female buckle seat 21, and the second driving member 44 can drive one end of the deflection shaft 41 to swing around the base 43; the deflection shaft 41 is provided with a first connecting rod 45, the driving end of the first driving member 42 is connected to the first connecting rod 45, and the first driving member 42 can drive the first connecting rod 45 to rotate around the deflection shaft 41, thereby driving the deflection shaft 41 to rotate around its axis.

[0043] It should be noted that when the first driving member 42 drives the deflection shaft 41 to rotate around its axis through the first connecting rod 45, the deflection direction of the female buckle seat 21 is the first direction; when the second driving member 44 drives one end of the deflection shaft 41 to swing around the base 43, the other end of the deflection shaft 41 also swings around the base 43, thereby driving the female buckle seat 21 to swing around the base 43. At this time, the deflection direction of the female buckle seat 21 is the second direction.

[0044] When the driving mechanism 30 drives the male buckle seat 22 to perform linear reciprocating motion, so that the male buckle and the female buckle are repeatedly engaged and separated, the female buckle seat 21 is deflected in the first direction or the second direction through the deflection device 40, thereby simulating the engagement and disengagement methods of the four-button buckle during actual use, thereby reducing test errors and greatly improving the accuracy of the test results.

[0045] Further, the base 43 is provided with a spherical through hole 431, and the spherical through hole 431 passes through the upper surface and the lower surface of the base 43. Optionally, the base 43 is in the shape of a rectangular parallelepiped, and the center of the spherical through hole 431 coincides with the center of the base 43. The deflection shaft 41 is provided with a deflection ball 46 corresponding to the spherical through hole 431, and the deflection ball 46 is sleeved in the spherical through hole 431, and the diameter of the deflection ball 46 is slightly smaller than the diameter of the spherical through hole 431, so that the deflection ball 46 can rotate in the spherical through hole 431. The deflection shaft 41 passes through the spherical through hole 431, and the deflection shaft 41 is located on an axis of the deflection ball 46. It should be noted that the diameter of the spherical through hole 431 located on the upper surface and the lower surface of the base 43 is larger than the diameter of the deflection shaft 41 , so that the deflection shaft 41 can not only rotate around its axis but also swing around the base 43 .

[0046] Further, a semicircular ball 47 is provided at one end of the deflection shaft 41 away from the female buckle seat 21, and the second driving member 44 is a linear motor, and a swing seat 48 is provided on the linear motor, and a semicircular groove 481 corresponding to the semicircular ball 47 is provided on the swing seat 48. The semicircular ball 47 is embedded in the semicircular groove 481, and when the linear motor drives the swing seat 48 to perform linear reciprocating motion, the swing seat 48 drives the deflection shaft 41 to perform swinging motion around the base 43 through the semicircular ball 47, thereby driving the female buckle seat 21 to swing around the base 43, that is, the female buckle seat 21 deflects in the second direction. It should be noted that when the distance between the semi-circular sphere 47 and the linear motor is shortest, the semi-circular sphere 47 is completely embedded in the semi-circular groove 481; when the distance between the semi-circular sphere 47 and the linear motor is farthest, no less than one-third of the semi-circular sphere 47 is still embedded in the semi-circular groove 481; when the distance between the semi-circular sphere 47 and the linear motor is farthest, the swing amplitude of the deflection shaft 41 reaches the maximum. At this time, the deflection shaft 41 fits with the hole wall of the spherical through hole 431, and is thereby limited by the hole wall of the spherical through hole 431, so that the deflection shaft 41 can no longer continue to increase the swing amplitude.

[0047] Furthermore, a narrow circular hole 432 is provided on the base 43, and the narrow circular hole 432 passes through the two side surfaces of the base 43. The first connecting rod 45 passes through the narrow circular hole 432. The first connecting rod 45 is located on an axis of the deflection ball 46, and the first connecting rod 45 and the deflection axis 41 are perpendicular to each other. Since the deflection axis 41 and the first connecting rod 45 are both located on an axis of the deflection ball 46, and the first connecting rod 45 and the deflection axis 41 are perpendicular to each other, when the deflection axis 41 swings around the base 43, the first connecting rod 45 rotates around its axis (that is, the relative position of the first connecting rod 45 and the deflection axis 41 remains unchanged). The first driving member 42 is a double-axis cylinder, and a circular ring 49 is provided at one end of the output shaft of the double-axis cylinder, and the first connecting rod 45 is sleeved on the circular ring 49. When it is necessary to drive the first connecting rod 45 to rotate around the deflection shaft 41, thereby driving the deflection shaft 41 to rotate around its axis, the two output shafts of the dual-axis cylinder extend and contract, and the extension and contraction amplitudes are equal, and the deflection shaft 41 can be driven to rotate around its axis by the first connecting rod 45, thereby realizing the deflection of the female buckle seat 21 in the first direction. It should be noted that when the amplitude of the deflection of the female buckle seat 21 in the first direction reaches the maximum, the first connecting rod 45 fits the hole wall of the narrow circular hole 432, and is limited by the hole wall of the narrow circular hole 432, so that the first connecting rod 45 can no longer continue to increase the rotation angle.

[0048] Furthermore, the button bite wear test device further includes a support base 50, and the support base 50 includes a first support foot 51, a first support plate 52, a second support plate 54, and a second support plate 54. The first support foot 51 is arranged on the inner bottom surface of the base 10, the first support plate 52 is arranged on the first support foot 51, and the second driving member 44 is arranged on the first support plate 52; the second support foot 53 is arranged on the first support plate 52, the second support plate 54 is arranged on the second support foot 53, and the first driving member 42 is arranged on the second support plate 54.

[0049] Furthermore, a base plate 11 is provided on the base 10, and the button seat 20 is provided at one end of the base plate 11. The driving mechanism 30 includes a driving motor 31, an eccentric shaft 33, a joint bearing 34, a linear bearing 32, and a second connecting rod 35. The driving motor 31 is provided at the other end of the base plate 11, and the driving motor 31 is provided in the base 10, and the output shaft of the driving motor 31 passes through the base plate 11 and extends to the upper end surface of the base plate 11; the eccentric shaft 33 is provided on the output shaft of the driving motor 31, that is, the axis of the eccentric shaft 33 is parallel to the axis of the output shaft of the driving motor 31 but is not on the same straight line, and when the output shaft of the driving motor 31 rotates, the eccentric shaft 33 is driven to rotate around the axis of the output shaft of the driving motor 31. One end of the joint bearing 34 is sleeved on the eccentric shaft 33, and the other end is connected to one end of the second connecting rod 35; the joint bearing 34 is rotatably connected to the eccentric shaft 33, and the joint bearing 34 includes a first joint rotatably connected to the eccentric shaft 33 and a second joint fixedly connected to the second connecting rod 35, and the first joint is rotatably connected to the second joint. The second connecting rod 35 is sleeved on the linear bearing 32, and the second connecting rod 35 is slidably connected to the linear bearing 32, and the other end of the second connecting rod 35 is connected to the male buckle seat 22. When working, the drive motor 31 drives the eccentric shaft 33 to rotate around the axis of the output shaft of the drive motor 31, and the eccentric shaft 33 drives the joint bearing 34 and the second connecting rod 35 to move. When the eccentric shaft 33 rotates to the side where the output shaft of the driving motor 31 is away from the second joint, the eccentric shaft 33 is farthest from the end of the base plate 11 close to the button seat 20; when the eccentric shaft 33 rotates to the side where the output shaft of the driving motor 31 is close to the second joint, the eccentric shaft 33 is closest to the end of the base plate 11 close to the button seat 20; since the first joint and the second joint are rotationally connected, and the linear bearing 32 constrains the second connecting rod 35 to move in a straight line, the periodic rotational motion of the driving motor 31 can be converted into a linear reciprocating motion of the second connecting rod 35 through the joint bearing 34, so that the male buckle and the female buckle can be repeatedly engaged and separated.

[0050] Furthermore, a counting rod 36 is provided on the outer periphery of the output shaft of the driving motor 31. When the counting rod 36 rotates one circle, it represents that the output shaft of the driving motor 31 rotates one circle, that is, the button completes one fastening and unfastening action. A counting photoelectric sensor 61 corresponding to the counting rod 36 is provided on the substrate 11, so as to obtain the number of times the button is fastened during the test. A power switch 62, a control system 63 and a counter 64 are provided on the side wall of the base 10. The power switch 62 is electrically connected to the control system 63. The driving motor 31, the first driving member 42 and the second driving member 44 are all electrically connected to the control system 63. The counter 64 is electrically connected to the counting photoelectric sensor 61. A protective cover 12 is provided on the base 10. Handles 13 are provided at both ends of the base 10 to facilitate the carrying of the test device.

[0051] The embodiment of the present invention provides a button engagement wear test device, and the specific implementation method is as follows: during the test, the female buckle is fixed on the female buckle seat 21, and the male buckle is fixed on the male buckle seat 22, and the male buckle seat 22 is driven by the driving mechanism 30 to perform linear reciprocating motion, so that the male buckle and the female buckle are repeatedly engaged and separated, and when the preset number of engagements is reached, the wear degree of the button is checked and obtained, so as to evaluate its durability and reliability. In this process, the first driving member 42 drives the deflection shaft 41 to rotate through the first connecting rod, and the deflection shaft 41 drives the female buckle seat 21 to deflect in the first direction. At this time, the protruding part of the male buckle forms an angle with the first direction, and is inserted into the groove of the female buckle or pulled out from the groove of the female buckle at an inclined angle; the second driving member 44 drives the deflection shaft 41 to swing around the base 43, and the deflection shaft 41 drives the female buckle seat 21 to deflect in the second direction. At this time, the protruding part of the male buckle forms an angle with the second direction, and is inserted into the groove of the female buckle or pulled out from the groove of the female buckle at an inclined angle. The button bite wear testing device provided by the present invention can simulate the actual use of the snap button when testing the button bite wear, thereby reducing the test error and greatly improving the accuracy of the test result.

[0058] The deflection rules of the deflection device 40 include:

Optionally, the deflection angle is greater than 0° but less than 8°, and is flexibly adjusted by the control system 63 to simulate the buckling mode in different usage scenarios.

[0060] Deflection frequency: The number of engagements is divided into three equal parts, one of which is when no deflection occurs during engagement, one is when deflection occurs in the first direction during engagement, and one is when deflection occurs in the second direction.

[0061] The embodiment of the present invention can simulate the fastening and unlocking modes of the snap fastener in actual use through the deflection device 40, thereby reducing the test error and greatly improving the accuracy of the test result.
