[0036] To achieve the above objectives, a second aspect of the present invention provides a method for attaching a button using a button-attaching machine, comprising the following steps:

[0037] S1, The buckle is placed in the upper clamp of the upper clamp assembly, and the upper clamp limits the buckle. The bottom of the upper clamp has a pressing plane.

[0038] S2, The buckle face is placed in the lower clamping body of the lower clamping assembly, and the lower clamping body limits the buckle face. The top of the lower clamping body has a pressing plane.

[0039] S3, Place the fabric on the top clamping plane of the lower clamp;

[0040] S4, the upper clamping body presses down, so that the pressing plane presses against the upper surface of the fabric, and the upper and lower clamping bodies flatten and clamp the fabric.

[0041] S5, the upper mold assembly presses down, the upper mold assembly drives the buckle body in the upper clamp to break free from the restraint of the upper clamp, and the buckle body is connected to the buckle surface through the fabric.

[0042] Furthermore, when the upper clamping body presses down to press the pressing plane onto the upper surface of the fabric, the lower clamping body descends simultaneously, so that the fastening surface protrudes from the lower clamping body. Under the action of the lower mold rod, the fastening surface is connected to the fastening body through the fabric.

[0043] With the above structure, the anti-wrinkle buttoning machine and buttoning method of the present invention have at least the following beneficial effects:

[0044] First, during use, when the fastener is connected to the fabric and the fastener body, the pressing plane presses on the upper surface of the fabric, and the supporting plane presses on the lower surface of the fabric. This makes the fabric around the fastening position pressed tight during the fastening process, thus making the fabric less prone to wrinkling.

[0045] Second, by setting up a drive mechanism and an upper mold assembly, the drive motor drives the main shaft to rotate, the rotation of the main shaft drives the connecting column to rotate, and the rotation of the connecting column drives the connecting rod to press down, thereby driving the upper mold assembly to press down, so that the upper clamping body is pressed down and close to the lower clamping body. By setting up a first feeding mechanism and a second feeding mechanism, the first feeding mechanism facilitates the supply of the buckle body to the upper clamping assembly, and the second feeding mechanism facilitates the supply of the buckle surface to the lower clamping assembly, thereby facilitating the connection between the fabric and the buckle body and buckle surface.

Detailed Implementation

[0061] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0062] like Figures 1 to 13 As shown, the present invention provides a wrinkle-resistant buttoning machine, which includes a frame 1, an upper clamping assembly 2, and a lower clamping assembly 3. The upper clamping assembly 2 is disposed on the frame 1 and includes an upper clamping body 21, the bottom of which forms a pressing plane 211. The lower clamping assembly 3 is disposed on the frame 1 and located below the upper clamping assembly 2. The lower clamping assembly 3 includes a lower clamping body 31, the top of which forms a pressing plane 311.

[0063] Thus, the anti-wrinkle buttoning machine of the present invention, when in use, when the button face is connected to the fabric and the button body, the pressing plane 211 presses against the upper surface of the fabric, and the pressing plane 311 presses against the lower surface of the fabric, so that during the buttoning process, the fabric around the buttoning position is pressed tightly, thereby making the fabric less prone to wrinkling.

[0064] Optionally, the system further includes a drive mechanism 4 and an upper mold assembly 5. The drive mechanism 4 is mounted on the frame 1, and the upper mold assembly 5 is connected to the drive mechanism 4 and driven downwards by the drive mechanism 4. An upper clamping assembly 2 is mounted at the end of the upper mold assembly 5. The drive mechanism 4 includes a drive motor, a main shaft 41, and a connecting rod 42. The drive motor is mounted inside the frame 1, and the main shaft 41 is connected to the drive motor and rotates under its influence. A connecting post 411 is located at a non-central position on the main shaft 41, and the connecting rod 42 is connected to the connecting post 411. Further, the system also includes a first feeding mechanism 6 and a second feeding mechanism 7. The first feeding mechanism 6 is located on one side of the frame 1 and is connected to the upper clamping assembly 2. The second feeding mechanism 7 is located on the other side of the frame 1 and is connected to the lower clamping assembly 3.

[0065] By setting up a drive mechanism 4 and an upper mold assembly 5, a drive motor drives the main shaft 41 to rotate. The rotation of the main shaft 41 drives the connecting column 411 to rotate. The rotation of the connecting column 411 drives the connecting rod 42 to press down, thereby driving the upper mold assembly 5 to press down, so that the upper clamping body 21 is pressed down and moves closer to the lower clamping body 31. By setting up a first feeding mechanism 6 and a second feeding mechanism 7, the first feeding mechanism 6 facilitates the supply of the buckle body to the upper clamping assembly 2, and the second feeding mechanism 7 facilitates the supply of the buckle surface to the lower clamping assembly 3, thereby facilitating the connection between the fabric and the buckle body and buckle surface.

[0066] like Figures 3 to 6 As shown, in this embodiment, the upper clamping assembly 2 further includes a first upper clamping claw 22, a second upper clamping claw 23, and an upper clamping spring 24; one end of the first upper clamping claw 22 is rotatably mounted on the upper clamping body 21, and the other end of the first upper clamping claw 22 is provided with a first upper clamping groove 221; the second upper clamping claw 23 is disposed opposite to the first upper clamping claw 22, one end of the second upper clamping claw 23 is rotatably mounted on the upper clamping body 21, and the other end of the second upper clamping claw 23 is provided with a second upper clamping groove 231, forming a clamping groove between the second upper clamping groove 231 and the first upper clamping groove 221; one end of the upper clamping spring 24 is connected to the first upper clamping claw 22, and the other end of the upper clamping spring 24 is connected to the second upper clamping claw 23, so that the second upper clamping groove 231 and the first upper clamping groove 221 tend to approach each other.

[0067] After the first feeding mechanism 6 provides the buckle body, the pushing mechanism pushes the buckle body into the clamping groove, so that the first upper clamping groove 221 is located on one side of the buckle body and the second upper clamping groove 231 is located on the other side of the buckle body. Under the action of the upper clamping spring 24, the first upper clamping groove 221 is pressed against one side of the buckle body and the second upper clamping groove 231 is pressed against the other side of the buckle body, thereby clamping the buckle body, thus stabilizing and restricting the buckle body, and facilitating the connection between the buckle surface and the fabric and the buckle body.

[0068] In this embodiment, an input port 25 is provided on the upper clamping body 21, which faces the clamping groove and is connected to the first feeding mechanism 6. By providing the input port 25, after the first feeding mechanism 6 provides the buckle body, the pushing mechanism can push the buckle body from the input port 25 into the clamping groove to clamp the buckle body.

[0069] Furthermore, the upper clamping body 21 includes a front frame 26 and a rear frame 27. A first mounting cavity for mounting the first upper clamping jaw 22 is formed between the front frame 26 and the rear frame 27. A second mounting cavity for mounting the second upper clamping jaw 23 is also formed between the front frame 26 and the rear frame 27. A first front connecting hole is provided on the front frame 26, a first rear connecting hole is provided on the rear frame 27, and a first through hole is provided on the first upper clamping jaw 22. The first through hole, the first rear connecting hole, and the first front connecting hole are located on the same straight line. A second front connecting hole is provided on the front frame 26, a second rear connecting hole is provided on the rear frame 27, and a second through hole is provided on the second upper clamping jaw 23. The second through hole, the second rear connecting hole, and the second front connecting hole are located on the same straight line.

[0070] During assembly, the first upper gripper 22 is placed in the first mounting cavity, which serves to restrict the first upper gripper 22. The second upper gripper 23 is placed in the second mounting cavity, which also serves to restrict the second upper gripper 23. After the first upper gripper 22 is placed in the first mounting cavity, a connecting pin can be used to pass through the first front connecting hole, the first through hole, and the first rear connecting hole in sequence, thereby allowing the first upper gripper 22 to be rotatably mounted on the upper clamping body 21. After the second upper gripper 23 is placed in the second mounting cavity, a connecting pin can be used to pass through the second front connecting hole, the second through hole, and the second rear connecting hole in sequence, thereby allowing the second upper gripper 23 to be rotatably mounted on the upper clamping body 21.

[0071] Preferably, the first upper gripper 22 is provided with a first guide surface 222 at its end, and the first guide surface 222 is located at the input end of the first upper clamping groove 221. The second upper gripper 23 is provided with a second guide surface 232 at its end, and the second guide surface 232 is located at the input end of the second upper clamping groove 231.

[0072] When the buckle body is placed in the first upper clamping groove 221, it moves along the first guide surface 222 and enters the first upper clamping groove 221, thus placing the buckle body in the first upper clamping groove 221. When the buckle body is placed in the second upper clamping groove 231, it moves along the second guide surface 232 and enters the second upper clamping groove 231, thus placing the buckle body in the second upper clamping groove 231. In this way, one side of the buckle body is clamped by the first upper clamping groove 221, and the other side of the buckle body is clamped by the second upper clamping groove 231, thereby stably restricting the buckle body and facilitating the connection between the buckle face and the fabric and the buckle body.

[0073] In this embodiment, a first slot 223 is provided on the outer side of the first upper jaw 22 for inserting one end of the upper clamping spring 24, and a second slot 233 is provided on the outer side of the second upper jaw 23 for inserting the other end of the upper clamping spring 24. By providing the first slot 223 and the second slot 233, during assembly, one end of the upper clamping spring 24 can be inserted into the first slot 223, and the other end of the upper clamping spring 24 can be inserted into the second slot 233. Under the action of the upper clamping spring 24, the second upper clamping slot 231 and the first upper clamping slot 221 tend to move closer to each other.

[0074] Furthermore, it also includes a spring snap fastener 28, which has a limiting opening 281 within it to restrict the upper clamping spring 24. The spring snap fastener 28 is disposed on the upper clamping body 21. The spring snap fastener 28 can be fixed to the upper clamping body 21 with screws, thereby restricting the upper clamping spring 24 and preventing the upper clamping spring 24 from detaching from the upper clamping body 21.

[0075] In this embodiment, a buffer elastic pad 29 is provided at the bottom of the upper clamp 21. The buffer elastic pad 29 protrudes from the pressing plane 211. When the pressing plane 211 presses down and presses the fabric, the buffer elastic pad 29 is compressed. The buffer elastic pad 29 plays a buffering role and reduces the impact force of the pressing plane 211 on the fabric.

[0076] like Figures 7 to 10 As shown, in a preferred embodiment of the present invention, the lower clamping assembly 3 further includes a lower mold base 32, a first lower clamping claw 33, a second lower clamping claw 34, and a lower clamping spring 35; the lower clamping body 31 is disposed on the lower mold base 32; the lower end of the first lower clamping claw 33 is rotatably disposed on the lower clamping body 31, and a first auxiliary positioning groove 331 is formed on the inner side of the upper end of the first lower clamping claw 33; the lower end of the second lower clamping claw 34 is rotatably disposed on the lower clamping body 31, and a second auxiliary positioning groove 341 is formed on the inner side of the upper end of the second lower clamping claw 34, and the second auxiliary positioning groove 341 is disposed opposite to the first auxiliary positioning groove 331; one end of the lower clamping spring 35 is connected to the first lower clamping claw 33, and the other end of the lower clamping spring 35 is connected to the second lower clamping claw 34, so that the first auxiliary positioning groove 331 and the second auxiliary positioning groove 341 tend to approach each other.

[0077] After the second feeding mechanism 7 provides the fastener face, the pushing mechanism pushes the fastener face into the lower clamping body 31, so that one side of the fastener face is restricted by the first auxiliary positioning groove 331 and the other side of the fastener face is restricted by the second auxiliary positioning groove 341, thereby effectively positioning the fastener face and making it less prone to displacement when connected with the fabric and the fastener body. By setting the lower clamping spring 35, the first auxiliary positioning groove 331 and the second auxiliary positioning groove 341 tend to move closer to each other, so that the first auxiliary positioning groove 331 fits against one side of the fastener face and the second auxiliary positioning groove 341 fits against the other side of the fastener face, thereby improving the positioning effect of the fastener face.

[0078] Furthermore, a first limiting groove 321 is formed on one side of the lower mold base 32, and a second limiting groove 322 is formed on the other side of the lower mold base 32; a first limiting plate 312 is provided on one side of the lower clamping body 31, the first limiting plate 312 being located within the first limiting groove 321, and a second limiting plate 313 is provided on the other side of the lower clamping body 31, the second limiting plate 313 being located within the second limiting groove 322. When the lower clamping body 31 is connected to the lower mold base 32, the first limiting plate 312 is placed within the first limiting groove 321, so that the first limiting groove 321 restricts the first limiting plate 312, and the second limiting plate 313 is placed within the second limiting groove 322, so that the second limiting groove 322 restricts the second limiting plate 313, thereby completing the docking of the lower mold base 32 and the lower clamping body 31, facilitating the locking of the lower clamping body 31 onto the lower mold base 32.

[0079] In this embodiment, a first connecting block 314 extends outward from one bottom side of the first limiting plate 312, and a first through hole is provided on the first connecting block 314. A second connecting block 315 extends outward from the other bottom side of the first limiting plate 312, and a second through hole is provided on the second connecting block 315. A first connecting channel is provided on the first lower gripper 33, and the first connecting channel, the second through hole, and the first through hole are located on the same straight line. A third connecting block 316 extends outward from one bottom side of the second limiting plate 313, and a third through hole is provided on the third connecting block 316. A fourth connecting block 317 extends outward from the other bottom side of the second limiting plate 313, and a fourth through hole is provided on the fourth connecting block 317. A second connecting channel is provided on the second lower gripper 34, and the second connecting channel, the fourth through hole, and the third through hole are located on the same straight line.

[0080] When the first lower jaw 33 is connected to the lower clamping body 31, a connecting pin is used to pass through the first through hole, the first connecting channel, and the second through hole in sequence, thereby enabling the first lower jaw 33 to be rotatably mounted on one side of the lower clamping body 31. When the second lower jaw 34 is connected to the lower clamping body 31, a connecting pin is used to pass through the third through hole, the second connecting channel, and the fourth through hole in sequence, thereby enabling the second lower jaw 34 to be rotatably mounted on the other side of the lower clamping body 31.

[0081] Furthermore, a first guide arc surface 332 is provided on the inner side of the upper end of the first lower gripper 33, and the first guide arc surface 332 is located at the front end of the first auxiliary positioning groove 331; a second guide arc surface 342 is provided on the inner side of the upper end of the second lower gripper 34, and the second guide arc surface 342 is located at the front end of the second auxiliary positioning groove 341. By providing the first guide arc surface 332 and the second guide arc surface 342, when the fastening surface is guided, the fastening surface moves along the first guide arc surface 332 and the second guide arc surface 342, thereby ensuring that the first auxiliary positioning groove 331 fits against one side of the fastening surface and the second auxiliary positioning groove 341 fits against the other side of the fastening surface, thus achieving the positioning of the fastening surface.

[0082] In this embodiment, the inner side of the first lower gripper 33 forms a first contact surface 333 that adheres to the first limiting plate 312, and the inner side of the second lower gripper 34 forms a second contact surface 343 that adheres to the second limiting plate 313. Under the action of the lower clamping spring 35, the first contact surface 333 adheres to the first limiting plate 312, and the second contact surface 343 adheres to the second limiting plate 313.

[0083] Furthermore, a first clearance opening 318 is provided on one side of the lower clamping body 31 for the upper end of the first lower clamping claw 33 to be inserted, and a second clearance opening 319 is provided on the other side of the lower clamping body 31 for the upper end of the second lower clamping claw 34 to be inserted. By providing the first clearance opening 318 and the second clearance opening 319, it is ensured that the upper end of the first lower clamping claw 33 is inserted into the lower clamping body 31, and that the upper end of the second lower clamping claw 34 is inserted into the lower clamping body 31, thereby limiting the buckling surface inside the lower clamping body 31 by the second lower clamping claw 34 and the first lower clamping claw 33.

[0084] In this embodiment, a positioning member 36 is also included to connect the lower clamping body 31 and the lower mold base 32. The end of the positioning member 36 passes through the lower clamping body 31 and the lower mold base 32. A first clearance through hole 334 is formed in the middle of the first lower jaw 33 for one end of the positioning member 36 to pass through, and a second clearance through hole 344 is formed in the middle of the second lower jaw 34 for the other end of the positioning member 36 to pass through. An inlet is provided on the lower clamping body 31 for the fastening surface to be guided into the first limiting groove 321 and the second limiting groove 322.

[0085] By setting the positioning element 36, after the first limiting plate 312 is placed in the first limiting groove 321 and the second limiting plate 313 is placed in the second limiting groove 322 to complete the docking of the lower mold base 32 and the lower clamping body 31, the end of the positioning element 36 passes through the lower clamping body 31 and the lower mold base 32, thereby fixing the lower clamping body 31 onto the lower mold base 32. The assembly process is simple and convenient. By setting the inlet, the buckle surface can move along the first inlet arc surface 332 and the second inlet arc surface 342 through the inlet, so that the first auxiliary positioning groove 331 fits against one side of the buckle surface and the second auxiliary positioning groove 341 fits against the other side of the buckle surface, thereby achieving the positioning of the buckle surface.

[0086] In a preferred embodiment of the present invention, such as Figures 11 to 13As shown, it also includes a lowering blade main assembly 8, which includes a fixing plate 81, a main body seat 82, a discharge plate 83, a left groove block 84, and a right groove block 85. The fixing plate 81 is mounted on the frame 1, the main body seat 82 is mounted on the fixing plate 81, the discharge plate 83 is mounted on the main body seat 82, and the discharge plate 83 is provided with a docking interface 831 that connects to the output port of the second feeding mechanism 7. The left groove block 84 is located on one side of the discharge plate 83, and the right groove block 85 is located on the other side of the discharge plate 83. A discharge groove is formed between the right groove block 85 and the left groove block 84.

[0087] By setting the fixing plate 81, the main body seat 82, and the button plate 83, it is easy to fix the lower knife main body assembly 8 on the frame 1. By setting the left groove block 84 and the right groove block 85, the buckle surface can move along the discharge groove between the right groove block 85 and the left groove block 84, so that the buckle surface can be pushed into the lower clamp 31 by the pushing mechanism for limiting.

[0088] In order to facilitate the buckle face being pushed into the lower clamping body 31, a pushing mechanism is provided on the frame 1 to drive the buckle face in the discharge groove into the lower clamping body 31. At the same time, the pushing mechanism can also push the buckle face into the upper clamping body 21.

[0089] Furthermore, the lower die body assembly 8 also includes a lower die sleeve pull block 86, which is fixed to the end of the main body base 82. The upper end of the lower die sleeve pull block 86 extends to form a first limiting block 861; the end of the ejector plate 83 extends to form a second limiting block 832, which is disposed opposite to the first limiting block 861; one end of the lower die base 32 abuts against the first limiting block 861, and the other end of the lower die base 32 abuts against the second limiting block 832. By setting the first limiting block 861 and the second limiting block 832, the lower die base 32 is easily restricted.

[0090] In a preferred embodiment of the present invention, a lower mold assembly 87 is further included. The lower mold assembly 87 includes a lower mold spring seat 871, a lower mold sliding sleeve 872, a lower mold spring 873, a load-limiting spring seat 874, an overload spring 875, and a lower mold rod 876. The lower mold spring seat 871 is fixed to the bottom of the main body seat 82, and a first mounting groove is formed in the lower mold spring seat 871. A sliding channel is formed in the main body seat 82. The lower mold sliding sleeve 872 is movably disposed in the sliding channel, and a mold rod slide is formed in the lower mold sliding sleeve 872. The lower mold spring 873 is disposed in the first mounting groove, and one end of the lower mold spring 873 abuts against the bottom of the first mounting groove. The other end of the lower mold spring 873 abuts against the bottom of the lower mold sleeve 872. The lower mold spring 873 is sleeved on the lower mold rod 876. The load-limiting spring seat 874 is set at the bottom of the lower mold spring seat 871. A second mounting groove is formed in the load-limiting spring seat 874. The overload spring 875 is set in the second mounting groove. The lower mold rod 876 includes a head 8761 and a rod 8762. The head 8761 is set in the second mounting groove and abuts against the end of the overload spring 875. The rod 8762 is integrally formed with the head 8761. The rod 8762 passes through the lower mold spring 873 and the lower mold sleeve 872 and is located in the lower clamping body 31.

[0091] The bottom of the lower mold base 32 abuts against the top of the lower mold sleeve 872, while the bottom of the lower mold sleeve 872 abuts against the lower mold spring 873. Under the action of the lower mold spring 873, the lower mold base 32 is driven to press against the first limiting block 861 and the second limiting block 832, thus restricting the lower mold base 32.

[0092] When the upper clamping body 21 is pressed down, it drives the lower clamping body 31 to move downward, compressing the lower mold spring 873. This causes the fastening face to protrude from the lower clamping body 31, achieving the connection between the fastening face and the fabric and the fastening body. By setting an overload spring 875, the fastening machine is protected against overload to prevent damage to the fastening machine.

[0093] Furthermore, a mold rod channel is provided on the lower clamping body 31 for the lower mold rod 876 to pass through. By providing the mold rod channel, after the buckle face is placed on the lower clamping body 31, the lower mold rod 876 rests on the bottom of the buckle face, so that when the lower clamping body 31 moves down, the buckle face does not move, thus realizing the connection between the buckle face and the fabric and the buckle body.

[0094] To facilitate the installation of the overload spring 875 into the load-limiting spring seat 874, a screw plug 8741 is provided at the bottom of the load-limiting spring seat 874. During installation, the screw plug 8741 can be unscrewed, the overload spring 875 can be placed into the load-limiting spring seat 874, and the screw plug 8741 can be tightened to complete the installation of the overload spring 875.

[0095] Furthermore, the bottom of the lower mold spring seat 871 is provided with a plug ring 8711 for inserting into the load-limiting spring seat 874. By providing the plug ring 8711, it is easy to insert into the load-limiting spring seat 874. The load-limiting spring seat 874 is provided with a limiting ring 8742. The head 8761 of the lower mold rod 876 abuts against the limiting ring 8742. By providing the limiting ring 8742, it is ensured that the head 8761 of the lower mold rod 876 is located inside the load-limiting spring seat 874.

[0096] This invention also provides a method for attaching buttons using a button-attaching machine, comprising the following steps:

[0097] S1, The buckle body is placed inside the upper clamping body 21 of the upper clamping assembly 2, and the upper clamping body 21 limits the buckle body. The bottom of the upper clamping body 21 has a pressing surface 211. S2, The buckle face is placed inside the lower clamping body 31 of the lower clamping assembly 3, and the lower clamping body 31 limits the buckle face. The top of the lower clamping body 31 has a pressing surface 311. S3, The fabric is placed on the pressing surface 311 of the lower clamping body 31. S4, The upper clamping body 21 is pressed down, so that the pressing surface 211 presses against the upper surface of the fabric. The upper clamping body 21 and the lower clamping body 31 flatten and clamp the fabric. S5, The upper mold assembly 5 is pressed down, and the upper mold assembly 5 drives the buckle body inside the upper clamping body 21 to break free from the restraint of the upper clamping body 21, and connects the buckle body to the buckle face through the fabric. When the upper clamping body 21 presses down, causing the pressing plane 211 to press against the upper surface of the fabric, the lower clamping body 31 descends simultaneously, causing the fastening face to protrude from the lower clamping body 31. Under the action of the lower mold rod 876, the fastening face is connected to the fastening body through the fabric. In use, when the fastening face is connected to the fabric and the fastening body, the pressing plane 211 presses against the upper surface of the fabric, and the pressing plane 311 presses against the lower surface of the fabric. This ensures that the fabric around the fastening position is compressed during the fastening process, making the fabric less prone to wrinkling.

[0098] The above embodiments and figures are not intended to limit the product form and style of the present invention. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of the present invention.
