[0037] In the traditional process of opening the buttonholes of seamless shirts (pieces), because the ultrasonic machine does not have an automatic clamping and positioning function, employees need to manually mark the buttonhole positions with powder according to different style requirements, and then place them on the ultrasonic machine for opening. This process is tedious and visual alignment is prone to human error, which can easily lead to quality problems.

[0038] Based on this, the first aspect of this application provides an auxiliary positioning device to solve the problem of manually marking and positioning the cut pieces during the buttonhole opening process. To more clearly illustrate the structure of the auxiliary positioning device, it will be described below in conjunction with the accompanying drawings.

[0039] For example, please refer to Figure 1 and Figure 2 As shown, Figure 1 and Figure 2This is a schematic diagram of the auxiliary positioning device provided in one embodiment of this 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 controls 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 this application can achieve stable support and fixation of the cut piece 20 through the fixing mechanism 100, effectively avoiding the offset problem of the cut piece 20 during the subsequent buttonhole opening process and improving the opening accuracy. Simultaneously, the auxiliary positioning device of this application controls the fixing mechanism 100 to move along the first guide rail 200 through the controller. By simply selecting the desired mounting mode on the controller, the cut piece 20 can be automatically moved to a fixed point, eliminating the need for manual drawing of the buttonhole positions.

[0040] Please see Figure 3 As shown, Figure 3 This is a schematic diagram of the fixing device in one embodiment of this application. The fixing mechanism 100 includes a platform 110 and a fixing member 120. The platform 110 is used to place the cut piece 20, and the platform 110 has a through hole 111 for assisting the opening of the buttonhole of the cut piece 20. The fixing member 120 can cooperate with the platform 110 to press the cut piece 20 tightly.

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

[0042] In some embodiments, the fixing mechanism 100 further includes a second connector 140 and a first telescopic member 150. The second connector 140 is mounted on the platform 110, and the first telescopic member 150 is mounted on the second connector 140. The first telescopic member 150 is capable of driving the fixing member 120 to move relative to the platform 110 to press or release the cut piece 20.

[0043] In some embodiments, the fastening device has a combination of multiple second connectors 140 and a first telescopic member 150. Adding multiple second connectors 140 and a first telescopic member 150 helps improve the stability of the fastener 120 in pressing the cut piece 20, especially for thin cut pieces 20.

[0044] In some embodiments, the controller can be programmed to control the fixing device 100 to move along the first guide rail 200 at set intervals and a set number of times, thus adapting to the buttonhole positioning requirements of different types of cut pieces.

[0045] In some embodiments, the first telescopic component is a telescopic cylinder. The first telescopic component is capable of driving the fixed component to move linearly along the vertical direction (z-axis direction).

[0046] In some embodiments, the fixing device further includes a pressure trigger, which controls the first telescopic component to drive the fixing member to press the cut piece. Optionally, the pressure trigger is located below the frame so that the program of the pressure trigger can be triggered by foot pedal when the operator's hands are inconvenient.

[0047] Please see Figure 4 , Figure 4 This is a side view of an auxiliary positioning device according to one embodiment of this application. In some embodiments, the auxiliary positioning device further includes a ball joint 400. The ball joint 400 is mounted on the frame and is used to assist in supporting the platform 110. The ball joint can provide stable support when the platform 110 moves, and the friction between the ball joint and the platform is small, so it will not hinder the movement of the platform 110 and improve the smoothness of the device operation.

[0048] For example, please refer to Figure 3 As shown, to more clearly illustrate the structure of the auxiliary positioning device, Figure 3 The system adds mutually orthogonal x-axis, y-axis and z-axis to aid understanding. The xy plane formed by the x-axis and y-axis is the plane on which 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 an elongated through-hole 111 extending longitudinally (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 racetrack-shaped. Understandably, 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 40cm to 150cm. Optionally, the extension length of the through hole 111 can be, but is not limited to, 40cm, 50cm, 60cm, 70cm, 80cm, 90cm, 100cm, 120cm, 150cm, or other values ​​within the range of 40cm to 150cm. The aforementioned through hole 111 is used to assist in opening the buttonhole of the cut piece 20. Keeping the through hole 111 within the aforementioned size range helps to adapt the auxiliary positioning device to the processing steps of shirt cut pieces 20 of various sizes.

[0051] In some embodiments, the lateral (y-axis direction) extension length of the through hole 111 is 1cm to 3cm. The lateral length of the through hole 111 can be, but is not limited to, 1cm, 1.5cm, 2cm, 2.5cm, 3cm, or other values ​​within the range of 1cm to 3cm. 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 sagging of the cut piece 20, and improves the quality of subsequent buttonhole opening.

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

[0053] In some embodiments, the longitudinal extension length of the fastener 120 is 40cm to 150cm. Optionally, the extension length of the fastener 120 can be, but is not limited to, 40cm, 50cm, 60cm, 70cm, 80cm, 90cm, 100cm, 120cm, 150cm, or other values ​​within the range of 40cm to 150cm. The fastener 120 described above is used to assist in pressing the cut piece 20, keeping the fastener 120 within the above-mentioned size range, which helps to adapt the auxiliary positioning device to the processing steps of shirt cut pieces 20 of various sizes.

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

[0055] In some embodiments, the minimum distance between the projections of the through hole 111 and the fastener 120 on the stage 110 is 1cm to 10cm. The distance between the projections of the through hole 111 and the fastener 120 on the stage 110 can be, but is not limited to, 1cm, 2cm, 3cm, 4cm, 5cm, 6cm, 7cm, 8cm, 9cm, 10cm, or other values ​​within the range of 1cm to 10cm. For thin and soft fabric pieces 20, even after being pressed together by the fastener 120, localized wrinkles can still easily appear at relatively far locations. Maintaining the distance between the through hole 111 and the fastener 120 within the aforementioned range helps reduce the impact of unevenness of the fabric piece 20 on the quality of subsequent buttonhole openings.

[0056] In some embodiments, the fixing device further includes a first limiting member. The first limiting member 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, which helps to position the cut piece 20 at the 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 distance between the projections of the first limiting member and the through hole 111 on the stage 110 is 1cm to 10cm. The distance between the projections of the first limiting member and the through hole 111 on the stage 110 can be, but is not limited to, 1cm, 2cm, 3cm, 4cm, 5cm, 6cm, 7cm, 8cm, 9cm, 10cm, or other values ​​within the range of 1cm to 10cm. Understandably, in the positive direction of the y-axis, the projections of the fixing member, the through hole, and the first limiting member are sequentially distributed on the stage.

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

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

[0061] In some embodiments, the fixing device further includes a second limiting member. The second limiting member 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, which helps to position the cut piece 20 at the 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 limiting member is 1cm to 10cm. Optionally, the lateral extension length of the second limiting member can be, but is not limited to, 1cm, 2cm, 3cm, 4cm, 5cm, 6cm, 7cm, 8cm, 9cm, 10cm or other values ​​within the range of 1cm to 10cm.

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

[0065] In some embodiments, the positions of the first and second limiting members on the stage are adjustable. Optionally, the stage is made of metal, and the first and second limiting members are magnetic, thereby enabling convenient fixing and movement. By adjusting the positional relationship between the first and second limiting members and the through hole, different cut piece models can be accommodated.

[0066] In some embodiments, the auxiliary positioning device further includes a display screen, a first button 310, and a second button 320. The display screen 300 allows selection of a corresponding movement mode. The first button 310 controls the auxiliary positioning device to begin moving along a preset path. The second button 320 controls the auxiliary positioning device to terminate the current movement.

[0067] In a second aspect, this application provides an ultrasonic automatic drilling machine. To more clearly illustrate the structure of the auxiliary positioning device, the auxiliary positioning device will be described below in conjunction with the accompanying drawings.

[0068] Please see Figure 1 and Figure 4 The ultrasonic automatic hole-opening machine includes the aforementioned auxiliary positioning device and ultrasonic hole-opening device. The ultrasonic hole-opening device is connected to a controller, which controls the fixing mechanism 100 to move a set distance along the first guide rail 200 and controls the ultrasonic hole-opening device to open buttonholes on the cut piece at set nodes. The ultrasonic automatic hole-opening machine of this application includes the aforementioned auxiliary positioning device and ultrasonic hole-opening device. After the worker fixes the cut piece 20 through the fixing mechanism 100 of the auxiliary positioning device, they only need to select the corresponding operating mode through the controller. The auxiliary positioning device can then automatically move in segments according to the set position information and automatically open holes through the ultrasonic hole-opening device, which helps to improve the quality of buttonhole openings on the cut piece 20 and increase production efficiency.

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

[0070] In some embodiments, the stamped end of the second stamping member can protrude from the through hole 111.

[0071] In some embodiments, the stamping end of the second stamping member is shaped like a frustum. The diameter of the frustum is smaller than the lateral extension length of the through hole 111.

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

[0073] In some embodiments, the side of the first stamping member 500 closest to the retainer 120 in the lateral direction (y-axis direction) has an inwardly curved end. This arrangement helps to prevent the first stamping member 500 from being blocked by the retainer 120 when pressed down.

[0074] Example 1

[0075] This embodiment illustrates one of the workflows of the ultrasonic automatic hole-opening machine of this application for opening buttonholes on cut pieces 20.

[0076] The operator selects the set opening mode on the controller, stretches and spreads the cut piece 20 on the platform 110 with both hands, and makes the front end of the cut piece 20 abut against the first limiting member. After ensuring that the cut piece 20 is wrinkle-free, the operator triggers the pressing trigger with their foot, causing the fixing member 120 to descend and press down on the cut piece 20, thus completing the fixing of the cut piece 20.

[0077] The operator presses the first button 310, and the controller moves the fixing mechanism 100 to the set position. It also controls the relative movement of the first stamping component 500 and the second stamping component of the ultrasonic punching device to open a buttonhole on the cut piece 20. The above steps are repeated until the preset opening position is completed. Finally, the controller resets the fixing mechanism 100 and lifts the fixing member 120, completing all processes.

[0078] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
