[0037] In the traditional process of opening buttons for seamless shirts (cut pieces), because the ultrasonic machine does not have the function of automatic clamping and positioning, employees need to manually draw powder to position the buttons at non-fixed positions according to different style requirements, and then place them on the ultrasonic machine for opening holes. This process is cumbersome and the naked eye alignment is prone to human errors, which can easily lead to quality problems.

[0038] Based on this, the first aspect of the present application provides an auxiliary positioning device to solve the problem of manually applying powder to position the cut pieces during the button-opening process. In order to more clearly illustrate the structure of the auxiliary positioning device, the auxiliary positioning device will be introduced below in conjunction with the accompanying drawings.

[0039] For example, see Figure 1 and Figure 2 As shown, Figure 1 and Figure 2A schematic diagram of the structure of an auxiliary positioning device provided for one embodiment of the present application. The auxiliary positioning device includes a fixing mechanism 100, a first guide rail 200, a first driving component 210 and a controller. The fixing mechanism 100 is slidably connected to the first guide rail 200, the first driving component 210 is connected to the fixing mechanism 100, and the controller is used to control the first driving component 210 to drive the fixing mechanism 100 to move a set distance along the first guide rail 200. The auxiliary positioning device of the present application can achieve stable support and fixation of the cut piece 20 through the fixing mechanism 100, which can effectively avoid the offset problem of the cut piece 20 in the subsequent button opening process and improve the hole opening accuracy. At the same time, the auxiliary positioning device of the present application controls the fixing mechanism 100 to move along the first guide rail 200 through the controller. It only needs to select the required stapling mode on the controller to realize the automatic fixed-point movement of the cut piece 20 through the controller, and there is no need to manually draw the button opening point.

[0040] See also Figure 3 As shown, Figure 3 The fixing mechanism 100 includes a stage 110 and a fixing member 120. The stage 110 is used to place the cut piece 20. The stage 110 is provided with a through hole 111 for assisting the cut piece 20 in opening the button. The fixing member 120 can cooperate with the stage 110 to press the cut piece 20.

[0041] In some embodiments, the fixing mechanism 100 further includes a first connecting member 130 . The first connecting member 130 is slidably connected to the first guide rail 200 , and the stage 110 is mounted on the first connecting member 130 , that is, the stage 110 is slidably connected to the first guide rail 200 through the first connecting member 130 .

[0042] In some embodiments, the fixing mechanism 100 further includes a second connecting member 140 and a first telescopic member 150. The second connecting member 140 is mounted on the stage 110, and the first telescopic member 150 is mounted on the second connecting member 140. The first telescopic member 150 can drive the fixing member 120 to move relative to the stage 110 to compress or loosen the cut piece 20.

[0043] In some embodiments, the fixing device has a combination of multiple second connecting members 140 and first telescopic members 150. Adding multiple second connecting members 140 and first telescopic members 150 helps to improve the stability of the fixing member 120 in pressing the panel 20, especially for the pressing ability of thin panels 20.

[0044] In some of the embodiments, the controller may be programmed to control the fixing device 100 to move a set distance and a set number of times along the first guide rail 200, thereby meeting the button positioning requirements of different types of cut pieces.

[0045] In some embodiments, the first telescopic component is a telescopic cylinder. The first telescopic component can drive the fixing member to move linearly along a vertical direction (z-axis direction).

[0046] In some embodiments, the fixing device further comprises a material pressing trigger, through which the first telescopic component can be controlled to drive the fixing member to press the cut piece. Optionally, the material pressing trigger is arranged below the frame, so that the operator can trigger the material pressing trigger by foot-operation when the operator is unable to use both hands.

[0047] See also Figure 4 , Figure 4 1 is a side view of an auxiliary positioning device in an embodiment of the present application. In some embodiments, the auxiliary positioning device further includes a universal ball device 400. The universal ball device 400 is mounted on the frame, and the universal ball device 400 is used to assist in supporting the stage 110. The universal ball can provide stable support when the stage 110 moves, and the friction between the two is small, which will not hinder the movement of the stage 110, thereby improving the smoothness of the device operation.

[0048] For example, see Figure 3 As shown, in order to more clearly illustrate the structure of the auxiliary positioning device, Figure 3 Mutually orthogonal x-axis, y-axis and z-axis are added to assist in understanding, wherein an xy plane formed by the x-axis and the y-axis is the plane where the stage 110 is located, and the z-axis is perpendicular to the xy plane.

[0049] In some embodiments, the through hole 111 of the stage 110 is a long strip-shaped through hole 111 extending longitudinally (in the x-axis direction), and the extending direction of the through hole 111 is parallel to the moving direction of the first guide rail 200. Optionally, the opening shape of the through hole 111 is rectangular or track-shaped. It can be understood that the moving direction of the first guide rail 200 is the x-axis direction.

[0050] In some embodiments, the longitudinal extension length of the through hole 111 is 40 cm to 150 cm. Optionally, the extension length of the through hole 111 may be, but is not limited to, 40 cm, 50 cm, 60 cm, 70 cm, 80 cm, 90 cm, 100 cm, 120 cm, 150 cm or other values ​​within the range of 40 cm to 150 cm. The above-mentioned through hole 111 is used to assist the button opening of the cutting piece 20, and keeping the through hole 111 within the above-mentioned size range helps the auxiliary positioning device to adapt to the processing procedures of shirt cutting pieces 20 of various sizes.

[0051] In some embodiments, the lateral (y-axis direction) extension length of the through hole 111 is 1 cm to 3 cm. The lateral length of the through hole 111 may be, but is not limited to, 1 cm, 1.5 cm, 2 cm, 2.5 cm, 3 cm, or other values ​​within the range of 1 cm to 3 cm. Keeping the lateral extension length of the through hole 111 within the above range not only takes into account the size of the ultrasonic hole opening machine, but also reduces the problem of local sinking of the cut piece 20, thereby improving the quality of the subsequent button opening.

[0052] In some embodiments, the extending direction of the fixing member 120 is parallel to the longitudinal extending direction of the through hole 111 .

[0053] In some embodiments, the longitudinal extension length of the fixing member 120 is 40 cm to 150 cm. Optionally, the extension length of the fixing member 120 may be, but is not limited to, 40 cm, 50 cm, 60 cm, 70 cm, 80 cm, 90 cm, 100 cm, 120 cm, 150 cm, or other values ​​within the range of 40 cm to 150 cm. The fixing member 120 is used to assist in pressing the cut piece 20, and to keep the fixing member 120 within the above-mentioned size range, so as to help the auxiliary positioning device adapt to the processing procedures of shirt cut pieces 20 of various sizes.

[0054] In some embodiments, the length of the fixing member 120 extending in the height direction (z-axis direction) is 2 cm to 10 cm. Optionally, the length of the fixing member 120 extending in the height direction may be, but is not limited to, 2 cm, 3 cm, 4 cm, 5 cm, 6 cm, 7 cm, 8 cm, 9 cm, 10 cm or other values ​​within the range of 2 cm to 10 cm.

[0055] In some embodiments, the minimum spacing between the projection of the through hole 111 and the fixing member 120 on the stage 110 is 1 cm to 10 cm. The spacing between the projection of the through hole 111 and the fixing member 120 on the stage 110 may be, but is not limited to, 1 cm, 2 cm, 3 cm, 4 cm, 5 cm, 6 cm, 7 cm, 8 cm, 9 cm, 10 cm or other values ​​within the range of 1 cm to 10 cm. For thin and soft cut pieces 20, even after being compressed by the fixing member 120, local wrinkles are still likely to appear at a farther position. Keeping the distance between the through hole 111 and the fixing member 120 within the above range helps to reduce the impact of the unevenness of the cut piece 20 on the quality of the subsequent button door opening.

[0056] In some embodiments, the fixing device further includes a first limiting member which is mounted on the stage 110 and forms a protrusion relative to the plane of the stage 110 to limit the lateral position of the cut piece 20, thereby helping to place the cut piece 20 at a set processing position.

[0057] In some embodiments, the longitudinal extension direction (x-axis direction) of the first limiting member is parallel to the longitudinal extension direction of the through hole 111 .

[0058] In some embodiments, the minimum spacing between the first stopper and the projection of the through hole 111 on the stage 110 is 1 cm to 10 cm. The spacing between the first stopper and the projection of the through hole 111 on the stage 110 may be, but is not limited to, 1 cm, 2 cm, 3 cm, 4 cm, 5 cm, 6 cm, 7 cm, 8 cm, 9 cm, 10 cm or other values ​​within the range of 1 cm to 10 cm. It can be understood that in the positive direction of the y-axis, the projection of the fixing member, the through hole and the first stopper are sequentially distributed on the stage.

[0059] In some embodiments, the longitudinal extension length of the first limiter is 45 cm to 160 cm. Optionally, the extension length of the first limiter can be but is not limited to 45 cm, 50 cm, 60 cm, 70 cm, 80 cm, 90 cm, 100 cm, 120 cm, 150 cm, 160 cm or other values ​​within the range of 40 cm to 160 cm.

[0060] In some embodiments, the height (z-axis direction) of the first limiter is 0.1 cm to 2 cm. Optionally, the height of the first limiter can be but is not limited to 0.1 cm, 0.2 cm, 0.4 cm, 0.6 cm, 0.8 cm, 1 cm, 1.2 cm, 1.4 cm, 1.6 cm, 1.8 cm, 2 cm or other values ​​within the range of 0.1 cm to 2 cm.

[0061] In some embodiments, the fixing device further includes a second limiting member which is mounted on the stage 110 and forms a protrusion relative to the plane of the stage 110 to limit the longitudinal position of the cut piece 20, thereby helping to place the cut piece 20 at a set processing position.

[0062] In some embodiments, the lateral extension direction (y-axis direction) of the second limiting member is perpendicular to the longitudinal extension direction of the first limiting member.

[0063] In some embodiments, the lateral extension length of the second limiter is 1 cm to 10 cm. Optionally, the lateral extension length of the second limiter can be, but is not limited to, 1 cm, 2 cm, 3 cm, 4 cm, 5 cm, 6 cm, 7 cm, 8 cm, 9 cm, 10 cm or other values ​​within the range of 1 cm to 10 cm.

[0064] In some embodiments, the height (z-axis direction) of the second limiter is 0.1 cm to 2 cm. Optionally, the height of the second limiter can be, but is not limited to, 0.1 cm, 0.2 cm, 0.4 cm, 0.6 cm, 0.8 cm, 1 cm, 1.2 cm, 1.4 cm, 1.6 cm, 1.8 cm, 2 cm or other values ​​within the range of 0.1 cm to 2 cm.

[0065] In some embodiments, the positions of the first stopper and the second stopper on the stage are adjustable. Optionally, the stage is made of metal, and the first stopper and the second stopper have magnetic force, so that they can be fixed and moved more conveniently, and the positional relationship between the first stopper, the second stopper and the through hole can be adjusted to adapt to different types of cut pieces.

[0066] In some embodiments, the auxiliary positioning device further includes a display screen, a first button 310 and a second button 320. The corresponding movement mode is selected through the display 300. The auxiliary positioning device can be controlled to start moving according to the set path through the first button 310. The auxiliary positioning device can be controlled to terminate the current movement through the second button 320.

[0067] In a second aspect of the present application, an ultrasonic automatic hole opening machine is provided. In order to more clearly illustrate the structure of the auxiliary positioning device, the auxiliary positioning device will be introduced below in conjunction with the accompanying drawings.

[0068] See also Figure 1 and Figure 4 , the ultrasonic automatic hole punching machine includes the above-mentioned auxiliary positioning device and the ultrasonic hole punching device. Among them, the ultrasonic hole punching device is connected to the controller, and the controller can control the fixing mechanism 100 to move a set distance along the first guide rail 200 and control the ultrasonic hole punching device at a set node to open a button for the cut piece. The ultrasonic automatic hole punching machine of the present application includes the above-mentioned auxiliary positioning device and the ultrasonic hole punching device. After the employee fixes the cut piece 20 through the fixing mechanism 100 of the auxiliary positioning device, he only needs to select the corresponding operation mode through the controller, and the auxiliary positioning device can automatically move in sections according to the set position information and automatically open holes through the ultrasonic hole punching device, which helps to improve the quality of opening the button for the cut piece 20 and the production efficiency.

[0069] In some embodiments, the ultrasonic hole opening device includes a first stamping component 500, a second stamping component (not shown in the figure), a second telescopic component and a third telescopic component; the first stamping component 500 and the second stamping component are arranged on both sides of the through hole 111 opposite to each other, the second telescopic component is used to drive the first stamping component 500 to move relative to the stage 110, and the third telescopic component is used to drive the second stamping component to move relative to the stage 110.

[0070] In some embodiments, the punching end of the second punching member can pass through the through hole 111 .

[0071] In some embodiments, the stamping end of the second stamping component is in the shape of a frustum, and the diameter of the frustum is smaller than the lateral extension length of the through hole 111 .

[0072] In some embodiments, the second telescopic component and the third telescopic component are telescopic cylinders.

[0073] In some embodiments, the first stamping component 500 has a side close to the fixing member 120 in the transverse direction (y-axis direction) and has an inwardly concave arc surface at its end. This arrangement helps to prevent the first stamping component 500 from being blocked by the fixing member 120 when pressing down.

[0074] Example 1

[0075] This embodiment illustrates one of the workflows of the ultrasonic automatic hole punching machine of the present application for opening a button for a cut piece 20 .

[0076] The operator selects the set hole opening mode on the controller, stretches and spreads the cut piece 20 on the stage 110 with both hands, and makes the front end of the cut piece 20 contact the first stopper. When ensuring that the cut piece 20 has no wrinkles, the operator triggers the material pressing trigger with his foot, so that the fixing member 120 descends and presses the cut piece 20, thereby fixing the cut piece 20.

[0077] The operator presses the first button 310, and the controller controls the fixing mechanism 100 to move to the set position, and controls the first punching component 500 and the second punching component of the ultrasonic hole opening device to move relative to each other to open a button door on the cut piece 20, and then repeats the above steps until the preset hole opening position is completed. Finally, the controller resets the fixing mechanism 100 and lifts the fixing member 120 to complete all processes.

[0078] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
