Description

Technical Field

[0001] This application relates to the field of sewing equipment technology, and in particular to an automatic button feeding device for adjusting button angle. Background Technology

[0002] A button sewing machine is a specialized automatic sewing machine that sews buttons with regular shapes and performs sewing processes such as attaching labels, tags, and caps.

[0003] Currently, buttons are automatically fed into the button-attaching machine using an automatic button-feeding device. With technological advancements, more and more buttons feature logos, requiring that the logos on all buttons face the same direction after the button-attaching machine completes the process. This necessitates that the automatic button-feeding device not only automatically feeds the buttons into the machine but also identifies the buttons and rotates them to a specified angle. Summary of the Invention

[0004] Therefore, it is necessary to provide an automatic button feeding device that can identify buttons and rotate the button position to a specified angle.

[0005] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0006] An automatic button feeding device for adjusting button angle includes a button feeding mechanism, an angle recognition mechanism, and an angle adjustment mechanism;

[0007] The fastening mechanism includes a fastening arm, a fastening claw, and a drive structure. The drive structure is connected to the fastening arm, and the fastening claw is rotatably connected to the fastening arm. The fastening claw has a first surface and a second surface that are arranged opposite to each other in the height direction of the fastening device. The first surface is used to position the button, and the second surface faces the angle adjustment mechanism.

[0008] The angle recognition mechanism is used to acquire button images and identify the button angle based on the button images;

[0009] The angle adjustment mechanism includes a docking member, which is engaged with the second surface and is capable of rotating about a vertical axis.

[0010] The snap claw has a first position and a second position. Under the drive of the drive structure, the snap claw is moved between the first position and the second position by the snap feeding arm. When the snap claw is in the first position, the docking member docks with the second surface and drives the snap claw to rotate so as to adjust the button to a set angle according to the identified button angle.

[0011] Understandably, the angle recognition mechanism, the latch, and the angle adjustment mechanism are arranged in layers along the height of the device. The moving components of the angle adjustment mechanism will not enter the field of view of the angle recognition mechanism's lens, ensuring unobstructed movement throughout the process. This guarantees complete button image acquisition, stable viewing angle, and recognition accuracy unaffected by structural interference, resulting in more accurate angle recognition results. In contrast to the top-mounted angle adjustment mechanism design, a top-mounted structure typically requires an additional horizontal drive mechanism to move or avoid the latching mechanism and accommodate workstation switching. This bottom-mounted design eliminates the need for horizontal movement freedom in the angle adjustment mechanism, retaining only vertical docking and rotational angle adjustment actions. This reduces drive components and transmission structures, lowers equipment complexity, and simplifies electrical control logic. Furthermore, utilizing the unused space below the latch to house the angle adjustment mechanism fully utilizes vertical space, eliminating the need for clearance around the image acquisition and latching areas. This results in a more compact overall structure and a smaller installation footprint. The drive structure moves the button-feeding arm and the button claw, allowing the button claw to move to multiple positions. This movement enables multi-station switching, stably transporting buttons to different stations such as button picking, image acquisition and angle adjustment, and button feeding. The process flow is smooth, resulting in higher button feeding efficiency and positioning accuracy. It is also compatible with various application scenarios, including button picking and feeding. The docking part and the second surface of the button claw use a clutch connection: when the docking part moves upwards to dock, it transmits rotational torque to adjust the angle; after adjustment, the two separate; after separation, the button claw can move freely for feeding. Combined with the layered layout, angle adjustment, image acquisition, and button feeding can be performed sequentially and in a time-separated manner, with each process independent of the others, resulting in a smooth equipment operating cycle.

[0012] In one embodiment, the driving structure includes a first driving member connected to the buckle feeding arm for driving the buckle feeding arm to move linearly in the horizontal direction.

[0013] Understandably, the first driving component drives the buckle feeding arm to move horizontally in a straight line, which in turn drives the buckle claw to complete multi-station switching such as buckle picking, angle recognition and adjustment, and buckle feeding.

[0014] In one embodiment, the drive structure further includes a second drive member and a third drive member, wherein the second drive member is connected to the first drive member and to the third drive member, and the third drive member is connected to the buckle feeding arm;

[0015] Under the drive of the first driving member, the second driving member, the third driving member, and the buckle feeding arm move linearly in the horizontal direction. Under the drive of the second driving member, the third driving member and the buckle feeding arm move linearly in the vertical direction. The third driving member is used to drive the buckle feeding arm to swing horizontally around the vertical axis.

[0016] Understandably, through the cooperation of three sets of drive components, the button feeding arm can achieve multi-dimensional movement including horizontal movement, vertical lifting and lowering, and horizontal swinging, thereby completing multi-station transfer of buttons, high and low position adaptation, and posture adjustment.

[0017] In one embodiment, the angle adjustment mechanism includes a fourth driving member and a fifth driving member. The fourth driving member is connected to the docking member for driving the docking member to rotate. The fifth driving member is connected to the fourth driving member for driving the fourth driving member to move in the vertical direction and causing the docking member to move synchronously.

[0018] Understandably, the fourth driving component drives the mating component to rotate, thereby adjusting the button angle. The fifth driving component drives the mating component to move vertically up and down, thus enabling the mating component to engage and disengage from the second surface of the snap claw. During engagement, power can be stably transmitted to complete the button angle adjustment. After disengagement, the mating component avoids movement space, ensuring the snap claw can move smoothly horizontally, effectively avoiding mechanical interference, and allowing the angle adjustment and snap feeding processes to coordinate in an orderly manner.

[0019] In one embodiment, the first surface is provided with at least two protrusions for engaging with holes on the button.

[0020] Understandably, the protruding post works in conjunction with the button hole to reliably limit the button's position, prevent displacement, and ensure the accuracy of image acquisition and angle recognition. On the other hand, it can synchronously drive the button to rotate with the buckle claw, avoiding relative slippage and improving the accuracy of angle adjustment. At the same time, the structure is simple, the material is unloaded smoothly, and it is suitable for automated buckle feeding operations.

[0021] In one embodiment, the second surface and one of the docking members are provided with docking teeth, and the other is provided with docking groove. The docking teeth and the docking groove engage to enable the docking member to drive the latch to rotate synchronously.

[0022] Understandably, by meshing the mating teeth and the mating groove, the mating parts and the latches can be reliably positioned and synchronously transmitted in the circumference, effectively preventing rotational slippage and improving the accuracy of angle adjustment; at the same time, it can be used in conjunction with vertical lifting actions to quickly achieve disengagement, ensuring smooth and reliable operation and adapting to automated continuous operation.

[0023] In one embodiment, the second surface is configured as a second friction surface, and the docking member is configured with a first friction surface, the first friction surface abutting against the second friction surface, for causing the docking member to drive the latch to rotate synchronously.

[0024] Understandably, the friction surface contact transmission has a simple structure, is easy to process, and has low cost; it can be used in conjunction with lifting actions to smoothly complete clutch engagement and disengagement, and the operation is stable and shock-free.

[0025] In one embodiment, the button feeding device further includes a feeding mechanism, and the button claw also has a third position. When the button claw is in the third position, the button claw docks with the output end of the feeding mechanism to take away the button output from the output end.

[0026] Understandably, the button claw first engages with the feeding mechanism at the third position to pick up the button, then moves to the first position to complete image recognition and angle adjustment, and finally moves to the second position to deliver the button to the button attaching machine. Relying on a single set of button claws, the entire process of button picking, angle adjustment, and button delivery is completed. The picking, angle adjustment, and discharging stations are independently zoned, with no interference between their actions, ensuring stable operation. The button does not shift twice throughout the process, resulting in higher imaging and angle adjustment accuracy. Furthermore, the reuse of the button delivery mechanism makes the overall machine structure compact.

[0027] In one embodiment, the feeding mechanism includes an eighth drive member and a feeding track. The output end of the eighth drive member is connected to a first end of the feeding track for feeding buttons onto the feeding track and feeding buttons along the feeding track. The second end of the feeding track is configured as the output end of the feeding mechanism.

[0028] Understandably, the eighth drive unit works with the feeding track to achieve automatic and orderly button conveying. The buttons are stably conveyed along the feeding track to the second end of the track for the button claw to pick up.

[0029] In one embodiment, a first track element and a second track element are respectively provided on both sides of the width of the feeding track. The second track element is fixed to the frame, and the first track element can be adjusted relative to the second track element to adjust the width of the feeding track.

[0030] Understandably, the first track element is movable and adjustable, allowing the track width to be adjusted according to the button size, thus adapting to the conveying of buttons of various specifications. Attached Figure Description

[0046] To ensure that the logo orientation on the buttons is consistent (as preset) after the button-attaching machine finishes attaching the buttons, the button feeding device needs to automatically feed the buttons to the machine while recognizing the logo orientation and rotating the logo to a specified angle.

[0047] Please see Figures 1 to 7 This application provides an automatic button feeding device 100 for adjusting the button angle, which is used in conjunction with a button attaching machine. It can identify the orientation of the button logo, rotate the logo to a specified angle, and finally transport the button 53 to the button attaching machine.

[0048] Specifically, the buckling device 100 includes a frame 60, a buckling mechanism 50, an angle recognition mechanism 10, and an angle adjustment mechanism 40, all of which are mounted on the frame 60.

[0049] The fastener feeding mechanism 50 includes a fastener feeding arm 51, a fastener claw 52, ​​and a drive structure. The drive structure is mounted on the frame 60 and connected to the fastener feeding arm 51 for driving the fastener feeding arm 51 to move. The fastener claw 52 passes through the fastener feeding arm 51 and is rotatably connected to the fastener feeding arm 51. The fastener claw 52 has a first surface 521 and a second surface 522 that are arranged opposite to each other in the height direction of the fastener feeding device 100, and the first surface 521 is higher than the second surface 522. The first surface 521 is used to position the button 53, and the second surface 522 faces the angle adjustment mechanism 40.

[0050] Angle recognition mechanism 10 is used to acquire button images and identify the button angle based on the button images. Angle recognition mechanism 10 includes an image acquisition unit and a recognition unit. The image acquisition unit is mounted on the frame 60 and is equipped with a lens. The image acquisition unit is higher than the first surface 521 and the lens faces the first surface 521. It is used to acquire button images and transmit the button images to the recognition unit. The recognition unit is used to process the button images and identify the button angle.

[0051] The angle adjustment mechanism 40 includes a docking member 46 and a fourth driving member 45. The fourth driving member 45 is mounted on the frame 60 and is connected to the docking member 46 in a transmission manner. The fourth driving member 45 is equipped with a controller, which is electrically connected to the identifier to obtain the angle of the button 53 and compare the button 53 angle with the set button 53 angle to calculate the angle at which the fourth driving member 45 needs to drive the docking member 46 to rotate. The docking member 46 is engaged and disengaged with the second surface 522.

[0052] The latch 52 has a first position and a second position. Under the drive of the drive structure, the latching arm 51 drives the latch 52 to switch between the first position and the second position. When the latch 52 is in the first position, the button 53 positioned on the latch 52 corresponds to the position of the lens and the docking member 46 in the vertical direction. When the docking member 46 is connected to the second surface 522, under the drive of the fourth drive member 45, the docking member 46 rotates around the vertical axis and drives the latch 52 to rotate to adjust the angle of the button 53. When the latch 52 is in the second position, the latching mechanism 50 sends the button 53 out from the latching device 100.

[0053] Here, the height direction of the device is set to the Z-axis, i.e., the up-down direction, or vertical direction. The horizontal movement direction of the latch 52 is set to the X-axis, i.e., the left-right direction, and the Y-axis is the front-back direction. When the latch 52 is in the first position, the image acquisition device is located above the latch 52, and the angle adjustment mechanism 40 is located below the latch 52. The downward horizontal projection of the image acquisition device lens, the latch 52, and the docking member 46 coincides, so that the image acquisition device can acquire the image of the button 53 positioned on the latch 52, and the docking member 46 can engage with the second surface 522 upwards. The second position is the button feeding position, corresponding to the button 53 input position of the button attaching machine. That is, in the second position, the button feeding mechanism 50 feeds the button 53 from the button feeding device 100 to the button attaching machine.

[0054] It is understandable that, in the height direction of the device, with the latch 52 as a reference, the image acquisition device is located above the first surface 521 of the latch 52, and the angle adjustment mechanism 40 is located below the second surface 522 of the latch 52. Therefore, the image acquisition device, the latch 52, and the angle adjustment mechanism 40 are arranged in layers in the height direction of the device. The moving components of the angle adjustment mechanism 40 will not enter the field of view of the lens, ensuring unobstructed operation throughout the process, guaranteeing complete image acquisition of the button 53, stable viewing angle, and recognition accuracy unaffected by structural interference, resulting in more accurate angle recognition results. Compared with the upper-mounted angle adjustment mechanism 40 scheme: if the upper-mounted structure needs to avoid the latch feeding mechanism 50 and adapt to workstation switching, it usually requires an additional horizontal drive mechanism to drive the angle adjustment mechanism 40 to follow or avoid it. The lower-mounted design of this scheme eliminates the need for the angle adjustment mechanism 40 to have horizontal movement freedom, retaining only vertical docking and rotational angle adjustment actions, reducing drive components and transmission structures, lowering equipment complexity, and simplifying electrical control logic. The angle adjustment mechanism 40 is arranged in the unused space below the buckle claw 52, ​​making full use of the vertical space. There is no need to reserve clearance space around the image acquisition area and buckle feeding area, resulting in a more compact overall structure and a smaller installation space. The drive structure drives the buckle feeding arm 51 and buckle claw 52 to move, allowing the buckle claw 52 to move to multiple positions. This enables the buckle claw 52 to switch between multiple workstations through movement, stably transporting the button 53 to different workstations such as buckle picking, image acquisition and angle adjustment, and buckle feeding. The process is smooth, the buckle feeding efficiency and positioning accuracy are higher, and it is also compatible with various usage scenarios such as buckle picking and buckle feeding.

[0055] The second surface 522 of the docking part 46 and the latch 52 adopts a clutch connection method: when the docking part 46 moves upward to dock, it transmits rotational torque to achieve angle adjustment, and the two separate after the angle adjustment is completed; after separation, the latch 52 can move freely to deliver the latch. Combined with the upper and lower layered layout, the angle adjustment action, image acquisition action, and feeding action can be carried out in a timed and orderly manner, and each process does not interfere with each other, and the device operates smoothly.

[0056] In one embodiment, the image acquisition device is equipped with a camera 11 and a light source 12. Both the camera 11 and the light source 12 are located above the first surface 521. The lens of the camera 11 faces the first surface 521 below. The light source 12 is close to the first surface 521 and is arranged in a ring to illuminate the first surface 521, which is beneficial for the camera 11 to acquire high-definition images of the button 53.

[0057] In one embodiment, the driving structure includes a first driving member 56, which is mounted on the frame 60 and connected to the buckle-feeding arm 51, for driving the buckle-feeding arm 51 to move linearly in the horizontal direction. It is understood that the first driving member 56 is used to drive the buckle-feeding arm 51 to move linearly in the horizontal direction, thereby enabling the buckle claw 52 to complete multi-station switching such as buckle picking, angle recognition and adjustment, and buckle delivery.

[0058] Furthermore, the fastening mechanism 50 also includes a second driving member 55 and a third driving member 54. The second driving member 55 is connected to the first driving member 56 and to the third driving member 54, and the third driving member 54 is connected to the fastening arm 51. Under the drive of the first driving member 56, the second driving member 55, the third driving member 54, and the fastening arm 51 move linearly in the horizontal direction. Under the drive of the second driving member 55, the third driving member 54 and the fastening arm 51 move linearly in the vertical direction. The third driving member 54 drives the fastening arm 51 to swing horizontally around the vertical axis.

[0059] Understandably, the first drive component 56 is used to realize the wide range of horizontal movement of the latch 52, the second drive component 55 is used to realize the height adjustment of the latch 52, and the third drive component 54 is used to realize the horizontal swing of the latch 52. Through the cooperation of the three sets of drive components, the latch feeding arm 51 and the latch 52 can realize multi-dimensional movement of horizontal movement, vertical lifting and lowering and horizontal swing, so as to complete the multi-station transfer, high and low position adaptation and posture adjustment of the button 53.

[0060] Specifically, the first driving component 56 includes a first cylinder 560, a first cylinder bracket 561, a first slide rail 562, and a first slider 563. The first cylinder 560 is connected to the first slider 563, the first slider 563 is slidably connected to the first slide rail 562, and is connected to the second driving component 55. The first cylinder 560 and the first slide rail 562 are mounted on the first cylinder bracket 561, and the first cylinder bracket 561 is mounted on the frame 60. Driven by the first cylinder 560, the first slider 563 slides along the first slide rail 562, thereby driving the second driving component 55 to move. The second driving component 55 includes a second cylinder 550, a second slide rail 552, and a second slider 553. The second cylinder 550 is connected to the second slider 553, the second slider 553 is slidably connected to the second slide rail 552, and is connected to the third driving component 54. The second cylinder 550 and the second slide rail 552 are mounted on the second cylinder bracket 551, which is connected to the first slider 563. Driven by the second cylinder 550, the second slider 553 slides along the second slide rail 552, causing the third driving member 54 to move. The third driving member 54 includes a third cylinder 543, a connecting rod 542, a swing shaft, and a support base 541. The support base 541 is connected to the second slider 553, and the swing shaft is rotatably mounted on the support base 541. The first end of the swing shaft is connected to the buckle-feeding arm 51. One end of the connecting rod 542 is hinged to the second end of the swing shaft, and the other end is hinged to the third cylinder 543. Driven by the third cylinder 543, the connecting rod 542 drives the swing shaft to rotate, thereby causing the buckle-feeding arm 51 to swing.

[0061] In one embodiment, the fourth driving member 45 is configured as a motor, and the output shaft of the motor is connected to the docking member 46 via a transmission connection. The fourth driving member 45 uses a motor to drive the docking member 46 to rotate, allowing for precise quantitative control of the rotation angle. It offers high angle adjustment accuracy, bidirectional speed adjustment, and easy integration with a vision recognition system, stably driving the latch 52 to rotate synchronously and correct the button 53's posture. For example, if the button 53's angle differs from the set button 53 angle by 10 degrees, the fourth driving member 45 needs to drive the docking member 46 to rotate by 10 degrees.

[0062] To position and rotate the button 53, at least two protrusions 5211 are provided on the first surface 521 for engaging with the holes on the button 53. The button 53 typically has two or four holes evenly distributed around its circumference; therefore, two protrusions 5211 can be provided, evenly distributed around the circumference of the first surface 521. The engagement of the protrusions 5211 with the holes in the button 53 reliably limits the button 53, preventing displacement and ensuring the accuracy of image acquisition and angle recognition. Furthermore, it can synchronously rotate the button 53 with the latch 52, avoiding relative slippage and improving the accuracy of angle adjustment. The structure is simple, the unloading is smooth, and it is suitable for automated button feeding operations.

[0063] In one embodiment, the angle adjustment mechanism 40 further includes a fifth driving member, which is connected to the fourth driving member 45 and is used to drive the fourth driving member 45 to move vertically and drive the docking member 46 to move synchronously. The fifth driving member is used to drive the docking member 46 to move vertically, thereby realizing the engagement and disengagement of the docking member 46 and the second surface 522 of the snap claw 52. When engaged, it can stably transmit power to complete the angle adjustment of the button 53. After disengagement, the docking member 46 avoids the movement space, ensuring that the snap claw 52 can move smoothly horizontally, effectively avoiding mechanism interference, and allowing the angle adjustment and snap feeding processes to cooperate in an orderly manner. The fifth driving member is configured as a fifth cylinder 41, which is mounted on the mounting plate 43. The mounting plate 43 is mounted on the frame 60. The fourth driving member 45 is mounted on the lifting plate 44. The lifting plate 44 is connected to the fifth cylinder 41 through the connecting plate 42. A slide rail mechanism can be provided between the lifting plate 44 and the mounting plate 43.

[0064] In one embodiment, one of the second surface 522 and the docking member 46 is provided with a docking tooth 461, and the other is provided with a docking groove 5221. The docking tooth 461 and the docking groove 5221 engage to enable the docking member 46 to drive the latch 52 to rotate synchronously. For example, the second surface 522 has two docking grooves 5221 evenly distributed circumferentially along the second surface 522, and the docking surface of the docking member 46 has docking teeth 461 evenly distributed circumferentially along the docking surface. Through the engagement of the docking teeth 461 and the docking groove 5221, reliable circumferential positioning and synchronous transmission between the docking member 46 and the latch 52 can be achieved, effectively preventing rotational slippage and improving angle adjustment accuracy; simultaneously, it can be used in conjunction with vertical lifting actions to quickly achieve disengagement, ensuring smooth and reliable operation and adapting to automated continuous operation. Understandably, the mating teeth 461 need to be aligned with the mating groove 5221 first, and then the fifth driving component drives the mating component 46 to rise vertically, so that the mating teeth 461 and the mating groove 5221 can mesh. This ensures that after the fourth driving component 45 drives the mating component 46 to rotate at a set angle, the LOGO orientation reaches the specified angle.

[0065] In another embodiment, the second surface 522 is configured as a second friction surface, and the mating member 46 is configured with a first friction surface. The first friction surface abuts against the second friction surface to enable the mating member 46 to drive the latch 52 to rotate synchronously. This friction surface abutment transmission method is simple in structure, easy to manufacture, and low in cost; it can smoothly complete the clutch engagement and disengagement in conjunction with lifting actions, and operates smoothly without impact.

[0066] In one embodiment, the fastening device 100 further includes a fastening mechanism 20. The fastening mechanism 20 includes a fastening member 21, a sixth driving member 22, and a seventh driving member 23. The sixth driving member 22 is connected to the fastening member 21 and is used to drive the fastening member 21 to rotate. The seventh driving member 23 is connected to the sixth driving member 22 and is used to drive the sixth driving member 22 to move linearly in the vertical direction. The latch 52 also has a third position, in which the button 53 is located at the output end of the feeding mechanism 30. When the latch 52 is in the third position, the pressing member 21 is higher than the output end of the feeding mechanism 30 and corresponds to the position of the button 53 in the vertical direction. Under the drive of the seventh driving member 23, the pressing member 21 presses against the button 53. Then, under the drive of the sixth driving member 22, the button 53 is rotated so that the protrusion 5211 on the latch 52 corresponds exactly to the hole on the button 53. In this way, after the latch 52 rises, the protrusion 5211 on the latch 52 is inserted into the hole on the button 53.

[0067] Preferably, the sixth driving member 22 is configured as a motor, and the output shaft of the motor is connected to the pressing member 21 for transmission. The pressing member 21 can be a rubber sleeve, which can flexibly press onto the button 53 and drive the button 53 to rotate. The seventh driving member 23 includes a seventh cylinder, a seventh slide rail, and a seventh slider. The seventh cylinder is connected to the seventh slider, the seventh slider is slidably connected to the seventh slide rail, and is connected to the sixth driving member 22. Driven by the seventh cylinder, the seventh slider slides along the seventh slide rail and drives the sixth driving member 22 to rise and fall. After the button 53 reaches the output end of the feeding mechanism 30, the pressing member 21 presses down and contacts the button 53. The sixth driving member 22 begins to reciprocate, thereby driving the button 53 to rotate. The pawl 52 moves upward under the action of the second driving member 55. When the button 53 rotates to a certain angle, the protrusion 5211 on the pawl 52 just inserts into the hole on the button 53, and the button 53 has been successfully retrieved.

[0068] In one embodiment, the button feeding device 100 further includes a feeding mechanism 30 for conveying the button 53 to the button picking position, i.e., the output end of the feeding mechanism 30. The button picking position corresponds to the third position of the button claw 52 and is located above the third position. The feeding mechanism 30 is mounted on the frame 60. When the button claw 52 is in the third position, it corresponds to the output end of the feeding mechanism 30 and is used to pick up the button 53 output from the output end. The button claw 52 first engages with the feeding mechanism 30 at the third position to pick up the button 53, then moves to the first position to complete image recognition and angle adjustment, and finally moves to the second position to complete the button feeding to the button attaching machine. The entire process of button picking, angle adjustment, and button feeding is completed using a single set of button claws 52. The picking, angle adjustment, and output stations are independently zoned, with no interference between their actions, resulting in stable operation. The button 53 does not shift twice throughout the process, leading to higher imaging and angle adjustment accuracy. Furthermore, the reuse of the button feeding mechanism 50 results in a compact overall structure.

[0069] Specifically, the feeding mechanism 30 includes an eighth driving member and a feeding track 31. The output end of the eighth driving member is connected to the first end of the feeding track 31, and is used to feed buttons 53 onto the feeding track 31 and to transport the buttons 53 along the feeding track 31. The second end of the feeding track 31 is configured as the output end of the feeding mechanism 30. The eighth driving member, in conjunction with the feeding track 31, enables the automatic and orderly feeding of buttons 53. The buttons 53 are stably fed along the feeding track 31 to the second end of the track for pickup by the clip 52. The eighth driving member can be configured as a vibrating feeder, and the discharge end of the discharge track of the vibrating feeder is connected to the first end of the feeding track 31. Due to the pushing action of the upstream buttons 53, the buttons 53 can be transported along the feeding track 31.

[0070] In one embodiment, the feeding track 31 includes a first track element 311 and a second track element 312 disposed on both sides of its width. The second track element 312 is fixed to the frame 60, and the first track element 311 can be adjusted relative to the second track element 312 to adjust the width of the feeding track 31. By adjusting the movement of the first track element 311, the track width can be adjusted according to the size of the button 53 to accommodate the feeding of various sizes of buttons 53. The movement adjustment of the first track can be achieved by driving with a cylinder or electric cylinder, or by manual adjustment with bolts and adjustment grooves. In addition, the feeding track 31 also includes a track top wall 313, which cooperates with the first track element 311 and the second track element 312 to form a feeding channel. The end of the track top wall 313 is provided with a notch 3131 for the fastener 21 to pass through and press against the button 53 at the buckle position.

[0071] In one embodiment, the feeding mechanism 30 further includes a retaining element 32, which includes a retaining plate 321, a Y-axis slider 322, a Y-axis slide rail 323, and a transmission element 324. The transmission element 324 drives the Y-axis slider 322 to slide along the Y-axis slide rail 323 and drives the retaining plate 321 to slide, thereby adjusting the distance between the retaining plate 321 and the output end of the feeding track 31, i.e., the size of the latching position. The front end of the output end of the feeding track 31 is open and closed by the retaining plate 321. At the same time, the bottom wall of the output end of the feeding track 31 has an opening, through which the protrusion 5211 on the latch 52 can pass and be inserted into the hole on the button 53.

[0072] If the size of the button 53 changes, the width of the feeding track 31 should correspondingly increase or decrease, and the size of the snap-on position should also correspondingly increase or decrease. To achieve synchronous adjustment of the width of the feeding track 31 and the size of the snap-on position, the first track element 311 is provided with a transmission groove 3111, which is obliquely positioned relative to the Y direction. The transmission component 324 is provided with a transmission part 3241, which cooperates with the transmission groove 3111. The transmission part 3241 can be a bearing, rollingly engaging with the transmission groove 3111. When the first track element 311 moves away from the second track element 312, the snap-on plate 321 moves away from the snap-on position; when the first track element 311 moves closer to the second track element 312, the snap-on plate 321 moves closer to the snap-on position, thus achieving synchronous adjustment of the snap-on position size and the width of the feeding track 31.

[0073] Furthermore, the feeding mechanism 30 also includes a lateral opening and closing unit 33, which includes a side baffle 331 and a baffle cylinder 332. The side baffle 331 is located on the right side of the output end of the feeding track 31, i.e., on one side of the second track element 312. The baffle cylinder 332 is mounted on a baffle bracket 333, which is mounted on the second track element 312. The baffle cylinder 332 is used to drive the side baffle 331 to rise and fall. When the baffle cylinder 332 drives the side baffle 331 to move upward, the latch 52 can enter the latching position from the right side. When the baffle cylinder 332 drives the latch plate 321 to move downward, the side baffle 331 closes the right side of the latching position, preventing the latch 52 from entering the latching position.

[0074] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0075] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the 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 scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
