[0045] Hidden buttons are used on the inside of clothing to fix or decorate. Because they are covered by the outer fabric and hidden inside the clothing, they do not affect the appearance of the clothing. In the field of clothing, nailing hidden buttons is a common process, mainly used on the front tube and other parts to prevent exposure.

[0046] In the related art, for buttons with large size and large aperture, machine buttoning can be used, and a customized mold is usually required to assist the buttoning process. Specifically, the mold is matched and set according to the size and shape of the button. After the button is placed in the specified position in the mold, the button sewing machine is started so that the button sewing machine sews the button through the mold according to the preset program and path. However, for small-sized and small-aperture hidden buttons, the adapted mold is difficult to process accurately, and the size of the processed mold is usually larger than the size of the hidden button. This situation may lead to the possibility of relative movement between the hidden button and the mold when the mold is used to assist the button sewing, so that the sewing needle will collide with the non-perforated part of the hidden button, that is, the problem of needle collision and needle breakage may occur, resulting in low efficiency of the hidden button sewing.

[0047] In order to solve the problem of low efficiency of buttoning of small-sized and small-diameter concealed buttons in the related art, firstly, referring to Figures 1 to 3 An embodiment of the present application provides a concealed buckle fixing structure 100, which includes a support base 110, two clamps 120 and a driving member. One end of the clamp 120 is rotatably connected to the support base 110, and the other end of the clamp 120 is provided with a groove 1200. The groove 1200 is used to accommodate the outer edge of the concealed buckle 300. When the concealed buckle 300 is clamped in the groove 1200, the through hole 310 on the concealed buckle 300 is located outside the groove 1200; the driving member is arranged on the support base 110, and the driving member is used to drive the two clamps 120 to move away from or approach each other.

[0048] In the present embodiment, the small-sized and small-diameter hidden button 300 refers to a hidden button 300 with a smaller diameter and a smaller hole 310, for example, a hidden button 300 with a diameter of 7 mm, a hole diameter of 0.8 mm, and a thickness of 1 mm. This type of hidden button 300 is not easy to be fixed by the mold in the prior art, or there is a possibility of shaking when fixed by the mold. Therefore, in the present embodiment, the clamp 120 and the driving member are used to clamp and fix this type of hidden button 300 with a smaller size and a smaller hole 310.

[0049] The opening shape of the groove 1200 matches the extension of the snap 300 . In this embodiment, the opening of the groove 1200 is in an arc shape for example, and the groove 1200 passes through the end wall of the clamp 120 to better accommodate the outer edge of the snap 300 .

[0050] Specifically, in the initial state, the clamps 120 are in a state of being close to each other. When the worker needs to insert the hidden button 300 into the groove 1200 for clamping, the two clamps 120 are driven away from each other by the driving member until the worker can insert the hidden button 300 between the two grooves 1200, and then the driving member is released, so that the two clamps 120 are close to each other until the outer edge of the hidden button 300 is clamped in the groove 1200. At this time, the perforation 310 on the hidden button 300 is located outside the groove 1200, so that the sewing needle 230 on the button sewing machine 200 can thread and sew the small-sized and small-diameter hidden button 300. In addition, the clamps 120 in this embodiment can simultaneously press the cut piece assembled with the hidden button 300, thereby replacing the setting of the presser foot in the related art, so that the structure of the button sewing machine 200 equipped with the hidden button fixing structure 100 is more concise and lightweight.

[0051] In this embodiment, the cooperation between the clamp 120 and the driving member helps to reduce the possibility of shaking of the concealed button 300, thereby ensuring stability during buttoning and greatly reducing the possibility of needle collision and needle breakage, which in turn helps to improve the buttoning efficiency of the concealed button 300.

[0052] Reference Figure 3 In some embodiments, the height of the groove 1200 is greater than the thickness of the hidden button 300, and the difference between the height of the groove 1200 and the thickness of the hidden button 300 is within a preset difference range.

[0053] Among them, the height of the groove 1200 is set to be greater than the thickness of the snap 300 in order to facilitate the insertion of the snap 300 into the groove 1200. However, in order to ensure the stability of the snap 300 after clamping, the difference between the height of the groove 1200 and the thickness of the snap 300 needs to be within a preset difference range.

[0054] Specifically, in this embodiment, taking the thickness of the hidden button 300 as 1 mm as an example, the height range of the groove 1200 is (1, 1.2] mm, that is, the preset difference range is (0, 0.2] mm, that is, the height of the groove 1200 can be 1.1 mm, 1.2 mm, etc., and a reasonable value can be selected within the height range.

[0055] Reference Figure 3 In some embodiments, when the snap button 300 is clamped in the groove 1200, the width of the extension of the snap button 300 pressed against the groove 1200 ranges from 0.8 to 1.2 mm.

[0056] Specifically, according to the above content, it can be known that when the hidden button 300 is clamped in the groove 1200, in order to facilitate the sewing needle 230 to smoothly pass through the perforation 310 on the hidden button 300, the perforation 310 needs to be exposed outside the groove 1200, and considering that the diameter of the hidden button 300 in this embodiment is relatively small, so, while ensuring that the perforation 310 can be smoothly exposed outside the groove 1200 when the hidden button 300 is clamped, it is also necessary to ensure the clamping force of the clamp 120 on the hidden button 300. Therefore, the width of the extension of the hidden button 300 pressed against the groove 1200 needs to be set in the range of 0.8~1.2mm. For example, in this embodiment, the width of the extension of the hidden button 300 pressed against the groove 1200 can be 0.8mm, 1mm or 1.2mm.

[0057] Reference Figure 2 In some embodiments, the support seat 110 includes a bottom plate 112, a connecting plate 114 and a top plate 116, wherein the connecting plate 114 is vertically arranged on the bottom plate 112; the top plate 116 is connected to the bottom plate 112 through the connecting plate 114, and an operating space is formed between the top plate 116 and the bottom plate 112, and one end of the top plate 116 away from the connecting plate 114 is rotatably connected to the clamp 120.

[0058] Specifically, the length of the bottom plate 112 is smaller than the length of the top plate 116, the bottom plate 112 and the top plate 116 are arranged horizontally and parallel to each other, and the number of connecting plates 114 is taken as two, the bottom end of the connecting plate 114 is vertically fixedly connected to the top wall of the bottom plate 112, the top end of the connecting plate 114 protrudes from the top wall of the top plate 116 and is fixedly connected to the top plate 116, and an operating space is enclosed between the top plate 116 and the bottom plate 112, and the bottom wall of the top plate 116 at one end away from the connecting plate 114 is rotatably connected to the end of the clamp 120 away from the groove 1200.

[0059] In this embodiment, the support base 110 provides a stable support for the clamp 120 , and the support base 110 also facilitates the installation of the clamp 120 on the button sewing machine 200 .

[0060] In some embodiments, the driving member includes a torsion spring, one end of the torsion spring is connected to the support seat 110 , and the other end of the torsion spring is connected to the clamp 120 .

[0061] Specifically, in the initial state, the two clamps 120 are close to each other. When the worker manually separates the two clamps 120, the torsion spring deforms greatly and the restoring force is also greater at this time. After the worker inserts the snap button 300 into the groove 1200 between the two clamps 120, the clamps 120 are released, so that the clamps 120 move toward each other in the horizontal direction under the action of the restoring force of the torsion spring to clamp the snap button 300.

[0062] In this embodiment, by providing the torsion spring, it is possible to ensure that the concealed buckle 300 is clamped and that the two clamps 120 do not move away from each other after clamping, thereby ensuring stable clamping of the concealed buckle 300.

[0063] Reference Figure 3 In some embodiments, the clamp 120 includes a connecting portion 122, a transition portion 124 and a clamping portion 126, one end of the connecting portion 122 is rotatably connected to the support seat 110; one end of the transition portion 124 is connected to the connecting portion 122, and the other end of the transition portion 124 is extended toward the groove 1200; the clamping portion 126 is horizontally arranged, and one end of the clamping portion 126 is connected to an end of the transition portion 124 away from the connecting portion 122, the groove 1200 is arranged at the other end of the clamping portion 126, and the clamping portion 126 is extended in a direction close to the other clamp 120, and the clamping portion 126 is also used to press the cut piece to be assembled with the hidden button 300.

[0064] The connecting portion 122, the transition portion 124 and the clamping portion 126 are integrally formed, the connecting portion 122 is horizontally arranged, and one end of the connecting portion 122 away from the transition portion 124 is rotatably connected to the support seat 110 through a rotating shaft. The transition portion 124 is inclined toward one side of the groove 1200, and the height of the transition portion 124 decreases from the end close to the connecting portion 122 to the end away from the connecting portion 122. The clamping portion 126 is horizontally arranged, and the two clamping portions 126 are arranged opposite to each other. One end of the connecting portion 122 away from the transition portion 124 is rotatably connected to the bottom wall of the top plate 116 through a rotating shaft, one end of the torsion spring is also connected to the connecting portion 122, and the other end of the torsion spring is connected to the bottom wall of the top plate 116.

[0065] Specifically, in the initial state, the two clamping parts 126 are close to each other. When the worker manually separates the two clamping parts 126 to insert the snap button 300, the two clamping parts 126 are reset under the action of the restoring force of the torsion spring and will not continue to rotate outward in the horizontal direction. Therefore, the snap button 300 can be stably clamped.

[0066] In other embodiments, the transition portion 124 may also be arranged in an arch shape and bent upward, and a plurality of weight-reducing holes may be arranged on the transition portion 124 to reduce the overall weight of the clamp 120 and improve the convenience of workers in manual operation.

[0067] The concealed button fixing structure 100 in the present application helps to reduce the possibility of shaking of the concealed button 300 through the cooperation of the clamp 120 and the driving member, thereby ensuring stability during buttoning, greatly reducing the possibility of needle collision and needle breakage, and further helping to improve the buttoning efficiency of the concealed button 300.

[0068] Reference Figure 1 , an embodiment of the present application further provides a button sewing machine 200, which is suitable for sewing nails of hidden buttons 300, and the button sewing machine 200 includes a body 210, a support platform 212, an extension platform 220 and a sewing needle 230. The button sewing machine 200 also includes any one of the hidden button fixing structures 100 provided in the first aspect, wherein the support platform 212 and the extension platform 220 are both horizontally connected to the outer wall of the body 210 located on the operating side of the button sewing machine 200, and the extension platform 220 is arranged above the support platform 212. A processing area is provided at one end of the support platform 212 located on the operating side of the button sewing machine 200, the above-mentioned hidden button fixing structure 100 is arranged on the support platform 212, and the clamp 120 is located above the processing area. The sewing needle 230 is arranged at one end of the extension platform 220 close to the operating side in the vertical direction, and the sewing needle 230 is arranged opposite to the processing area.

[0069] Specifically, after a worker stably clamps the small-sized and small-diameter hidden button 300 through the hidden button fixing structure 100, the perforation 310 on the hidden button 300 is exposed to the outside, and the sewing needle 230 is started to thread and sew the hidden button 300.

[0070] The button sewing machine 200 in this embodiment, after being equipped with any one of the concealed button fixing structures 100 provided in the first aspect mentioned above, also has the technical effect of reducing the possibility of shaking of the concealed button 300, thereby ensuring stability during button sewing, greatly reducing the possibility of needle collision and needle breakage, and further helping to improve the button sewing efficiency of the concealed button 300.

[0071] In some embodiments, the button sewing speed of the sewing needle 230 ranges from 580 r / min to 620 r / min.

[0072] Specifically, after a large number of tests, it was found that when the sewing needle 230 is thin and the machine speed is between 580 r / min and 620 r / min, it is not easy to hit the needle or break the needle. For example, the button sewing speed of the sewing needle 230 in this embodiment can be 600 r / min.

[0073] Thirdly, combining Figures 1 to 3An embodiment of the present application provides a method for fastening a concealed button, which is applied to any one of the fastening machines 200 provided in the second aspect above, and the method comprises the following steps:

[0074] Place the cut piece in the processing area, use the driving member to move the two clamps 120 away from each other, and clamp the button 300 in the grooves 1200 of the two clamps 120;

[0075] The two clamps 120 are moved closer to each other by a driving member so that the outer edges of both sides of the buckle 300 are clamped in the groove 1200;

[0076] The sewing needle 230 is started to thread and sew the button 300.

[0077] Specifically, the worker first places the cut piece in the processing area, and then manually separates the two clamps 120 so that the two grooves 1200 are away from each other, and then inserts the button 300 into the groove 1200, releases the clamps 120, so that the two clamps 120 are reset under the action of the driving member, that is, they are close to each other to clamp the button 300, and then starts the sewing needle 230 to thread and sew the button 300.

[0078] In some embodiments, starting the sewing needle 230 to thread and sew the hidden button 300 includes: when the distance between the outer edge of the hidden button 300 and the edge of the cutting piece is less than a preset distance threshold, controlling the sewing needle 230 to thread and sew the hidden button 300 in a figure-two shape; when the distance between the outer edge of the hidden button 300 and the edge of the cutting piece is not less than a preset distance threshold, controlling the sewing needle 230 to thread and sew the hidden button 300 in a figure-eight shape or a figure-two shape.

[0079] Since the distance between the hidden button 300 and the edge of the cut piece is small, it is inconvenient for the sewing needle 230 to thread the nail. Therefore, in this embodiment, when the edge distance is less than 5 mm, the sewing needle 230 can be controlled to sew the hidden button 300 as follows: Figure 4 In the case where the distance between the outer edge of the hidden button 300 and the edge of the cut piece is not less than 5 mm, the sewing needle 230 can be controlled to perform the following operations on the hidden button 300: Figure 5 The figure eight shape shown or Figure 4 The two-shaped threading staples shown, the specific stapling method can be set according to processing requirements.

[0080] The concealed button sewing method in the present application, after being equipped with any one of the button sewing machines 200 provided in the second aspect mentioned above, also has the technical effect of reducing the possibility of shaking of the concealed button 300, thereby ensuring the stability during sewing, greatly reducing the possibility of needle collision and needle breakage, and further helping to improve the sewing efficiency of the concealed button 300; in addition, the sewing efficiency of the concealed button 300 is further improved by the "two-shaped" threading and sewing method.
