Description

Technical Field

[0001] This application relates to the field of sewing equipment technology, and in particular to an automatic button marking recognition and button feeding device. 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 to the button-attaching machine using an automatic button-feeding device. With technological advancements, more and more buttons feature logos, requiring that the logos on the buttons face the same direction (or angle) after the button-attaching machine completes the process. This necessitates that the automatic button-feeding device, while automatically feeding the buttons to the machine, can also identify the logo's orientation, allowing it to rotate the button to a specified angle before it reaches the machine. Summary of the Invention

[0004] Therefore, it is necessary to provide an automatic button recognition and button feeding device that can identify the angle of the button mark.

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

[0006] An automatic button label recognition and button feeding device includes a recognition mechanism and:

[0007] The feeding mechanism has an output end configured as a button-grabbing position, which has a first surface and a second surface arranged opposite to each other, and the first surface is used to hold the button.

[0008] The button feeding mechanism includes a button claw, the button claw having a first positioning surface and a second positioning surface arranged opposite to each other, the first positioning surface being used to position the button;

[0009] A snap-fit ​​mechanism includes a snap-fit ​​element and a first drive structure, wherein the first drive structure is connected to the snap-fit ​​element and is used to drive the snap-fit ​​element to move horizontally, move vertically, and rotate.

[0010] The fastener has an initial position and a fastening position. When the fastener is in the fastening position, the first positioning surface is aligned with the second surface, and the fastener rotates to make the first positioning surface engage with the button's hole, positioning the button in the fastening position. When the fastener returns to the initial position, the recognition mechanism acquires an image of the button and identifies the button angle based on the image.

[0011] Understandably, the first drive structure drives the clamping component, enabling its multi-degree-of-freedom movement. The clamping component has two positions: a clamping position and an initial position. During the button alignment stage, it moves to the clamping position to clamp the button and rotate to align with the hole. After hole alignment, it returns to the initial position. The initial position is far from the image acquisition area above the snap-on position, and the clamping component is completely out of the image acquisition field of view, ensuring no obstruction of the button or shadows in the image, guaranteeing complete and clear image acquisition and avoiding recognition failures and angle judgment errors caused by obstruction. The clamping component descends to clamp the button and ascends to reset and disengage from the button. The rotation of the clamping component, combined with the clamping force, causes the button to rotate slightly, ensuring precise alignment between the button hole and the snap-on claw. Furthermore, the snap-on claw of the feeding mechanism moves below the snap-on position. The snap-on claw remains at the snap-on position, allowing for sequential snap-on and image recognition without multiple button transfers, shortening the movement stroke and improving feeding efficiency. The button is positioned and held by the snap-on claw throughout the process, without secondary displacement, ensuring a unified imaging benchmark and simultaneously improving recognition and angle adjustment accuracy.

[0012] In one embodiment, the feeding mechanism includes a first drive member and a feeding track. The output end of the first 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.

[0013] Understandably, the first 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 feeding track for the button claw to pick up and the recognition mechanism to perform image acquisition and recognition.

[0014] In one embodiment, the feeding track includes a first track element and a second track element disposed on both sides of the width, wherein the first track element is adjustable relative to the second track element to adjust the width of the feeding track.

[0015] 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.

[0016] In one embodiment, the buckle position has an opening, and the feeding mechanism further includes a stop block and a ninth driving member, the ninth driving member being connected to the stop block and used to drive the stop block to move along the width direction of the feeding track to open or close the opening.

[0017] Understandably, the ninth drive unit drives the stop block to move along the width of the track, controlling the opening and closing of the buckle-taking position. Closing the opening can prevent the button from detaching from the buckle-taking position. After the buckle claw grabs the button, it can open the buckle-taking position opening, making it convenient for the buckle claw to switch workstations while carrying the button.

[0018] In one embodiment, the feeding mechanism further includes a Y-axis slider, a Y-axis slide rail, and a transmission structure. The Y-axis slider is slidably connected to the Y-axis slide rail and connected to the ninth driving member. The input end of the transmission structure is connected to the first track element, and the output end of the transmission structure is connected to the Y-axis slider.

[0019] When the first track element is adjusted relative to the second track element, the transmission structure drives the Y-axis slider to slide along the Y-axis slide rail and drives the stop block to slide, so as to adjust the distance between the stop block and the opening.

[0020] Understandably, when the track width is adjusted to fit different button sizes by linking the first track element with the Y-axis slider and the stop through the transmission structure, the stop automatically adjusts the distance between the stop and the opening simultaneously, without the need for separate adjustment of the stop.

[0021] In one embodiment, the transmission structure includes a transmission member, the first track element is provided with a transmission groove, the transmission groove is obliquely arranged relative to the length direction of the first track element, the transmission member is provided with a transmission part, and the transmission part is in transmission cooperation with the transmission groove.

[0022] Understandably, the mechanical reversing transmission structure that uses an inclined transmission groove in conjunction with the transmission part can convert the width adjustment displacement of the first track element into the synchronous Y-direction displacement of the stop, thereby realizing the mechanical linkage between the track width and the stop limit position; the linkage stroke ratio is fixed and the synchronization accuracy is high, and there is no need to adjust the stop separately when changing the button specification.

[0023] In one embodiment, the feeding track further includes a track top wall, which together with the first track element and the second track element forms the feeding track. The end of the track top wall is provided with a notch for the passage of the snap fastener.

[0024] Understandably, the top wall of the track and the side track components together form a closed conveying channel, limiting the buttons' vertical and horizontal movement to ensure a regular conveying posture and prevent the buttons from stacking during transport. A notch is provided at the end of the top wall of the track to allow space for the pressing action of the fastener.

[0025] In one embodiment, the first driving structure includes a sixth driving member, a seventh driving member, and an eighth driving member. The sixth driving member is connected to the snap fastener and is used to drive the snap fastener to rotate. The seventh driving member is connected to the sixth driving member and is used to drive the sixth driving member to move in the vertical direction. The eighth driving member is connected to the seventh driving member and is used to drive the seventh driving member to move in the horizontal direction.

[0026] Understandably, the sixth, seventh, and eighth driving components work together to enable the buckle to move horizontally, vertically, and rotate.

[0027] In one embodiment, the buckle feeding mechanism further includes a second drive structure and a buckle feeding arm, the buckle claw passes through the buckle feeding arm and is rotatably connected to the buckle feeding arm, and the second drive structure is connected to the buckle feeding arm for driving the buckle feeding arm to move.

[0028] Understandably, the second drive structure drives the button feeding arm to move and enables the button claw to complete the multi-station transfer of the button.

[0029] In one embodiment, the second drive structure includes a second drive member and a third drive member, wherein the second drive member is drive-connected to the third drive member, and the third drive member is drive-connected to the buckle feeding arm.

[0030] Under the drive of the second driving member, the third driving member and the buckle feeding arm move linearly in the vertical direction, and the third driving member is used to drive the buckle feeding arm to swing horizontally around the vertical axis.

[0031] Understandably, by cooperating with two sets of drive components, the button feeding arm can achieve multi-dimensional movement of vertical lifting and horizontal swinging, thereby enabling the button to be adapted to different heights and transferred to multiple workstations.

[0046] To ensure that the logo (or mark) on the button is facing the same direction (or angle) after the button-attaching machine finishes attaching the button, the button feeding device needs to automatically feed the button to the machine, while also recognizing the orientation of the button logo and rotating it to a specified angle.

[0047] Please see Figures 1 to 6 This application provides an automatic button logo recognition and feeding device 100, which is used in conjunction with a button attaching machine. It can recognize the orientation of the button logo and rotate the logo orientation to a specified angle, and finally transport the button 53 to the button attaching machine.

[0048] Specifically, the fastening device 100 includes a feeding mechanism 30, a pressing mechanism 20, a fastening mechanism 50, and an identification mechanism 10.

[0049] The feeding mechanism 30 is mounted on the frame 60. The feeding mechanism 30 includes a feeding track 31. The output end of the feeding track 31 is configured as a snap-on position 314. The snap-on position 314 has a first surface 3141 and a second surface 3142 that are arranged opposite to each other in the height direction of the snap-on device 100. The first surface 3141 is higher than the second surface 3142. The first surface 3141 is used to support the button 53.

[0050] The fastener feeding mechanism 50 is mounted on the frame 60. The fastener feeding mechanism 50 includes a fastener feeding arm 51 and a fastener claw 52. 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 positioning surface 521 and a second positioning surface 522 that are arranged opposite to each other in the height direction of the fastener feeding device 100. The first positioning surface 521 is higher than the second positioning surface 522. The first positioning surface 521 is used to position the button 53.

[0051] The snap-fit ​​mechanism 20 is mounted on the frame 60. The snap-fit ​​mechanism 20 includes a snap-fit ​​member 21 and a first drive structure. The first drive structure is connected to the snap-fit ​​member 21 and is used to drive the snap-fit ​​member 21 to achieve horizontal movement, vertical movement and rotation.

[0052] The identification mechanism 10 is mounted on the rack 60. The identification mechanism 10 includes an image acquisition unit and an identifier. The image acquisition unit is mounted on the rack 60 and includes a lens. The image acquisition unit is higher than the first surface 3141 and the lens faces the first surface 3141. It is used to acquire the image of the button 53 and transmit the image of the button 53 to the identifier. The identifier is used to process the image of the button 53 and identify the (orientation) angle of the mark.

[0053] Here, the height direction of the fastening device 100 is set to the Z-direction, i.e., the up-down direction, and the horizontal movement direction of the fastening member 21 is set to the X-direction, i.e., the left-right direction. The Y-direction is the front-back direction. The positions of the feeding mechanism 30 and the identification mechanism 10 are fixed. The identification mechanism 10 is arranged with the fastening position 314 as a reference. The image acquisition device is located directly above the fastening position 314, and subsequent angle adjustments are also completed at the fastening position 314. In the X-direction, the fastening mechanism 20 and the fastening feeding mechanism 50 are generally offset from the feeding mechanism 30. For example, the fastening mechanism 20 is located to the left of the feeding mechanism 30, and the fastening feeding mechanism 50 is located to the right of the feeding mechanism 30. The fastening member 21 and the fastening claw 52 can move relative to the fastening position 314.

[0054] Understandably, the first drive structure drives the fastening component 21, enabling its multi-degree-of-freedom movement. The fastening component 21 has two positions: a fastening position and an initial position. During the button 53 alignment and correction stage, it moves to the fastening position to press the button 53 and rotates to align with the hole; after hole alignment is completed, it returns to the initial position. The initial position is far from the image acquisition area above the fastening position 314, and the fastening component 21 is completely out of the lens's field of view, ensuring it does not obstruct the button 53 or create shadows in the image, guaranteeing complete and clear image acquisition and avoiding recognition failure or angle judgment deviation caused by obstruction. The entire fastening action and image acquisition are executed in a time-sharing manner: first, the fastening component rotates to align with the hole; then, the fastening component 21 horizontally retracts to avoid obstruction; and finally, the lens acquires the image. The two sets of actions are completely separated in space and timing, ensuring that the correction process does not interfere with the visual recognition process, and the continuous operation has a stable cycle time. In addition, the latch 52 of the latching mechanism 50 moves to below the latching position 314. The latch 52 can complete the latching, image recognition, and angle adjustment sequentially by staying at the latching position 314, without the need for multiple transfers of the button 53, thus shortening the movement stroke and improving the latching efficiency. The button 53 is positioned and held by the latch 52 throughout the entire process without secondary displacement, ensuring a unified imaging reference and simultaneously improving the accuracy of recognition and angle adjustment.

[0055] The first driving structure includes a sixth driving member 22, a seventh driving member 23, and an eighth driving member 24. The sixth driving member 22 is connected to the snap fastener 21 and is used to drive the snap fastener 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 in the vertical direction and drive the snap fastener 21 to move synchronously. The eighth driving member 24 is connected to the seventh driving member 23 and is used to drive the seventh driving member 23 to move in the horizontal direction and drive the snap fastener 21 to move synchronously.

[0056] Driven by the eighth driving component 24, the snap fastener 21 switches between its initial position and the snap fastening position. The seventh driving component 23 drives the snap fastener 21 downward to press the button 53 and upward to reset and disengage from the button 53. The sixth driving component 22 drives the snap fastener 21 to rotate, which, in conjunction with the pressing force, causes the button 53 to rotate slightly, ensuring that the hole of the button 53 is precisely aligned with the snap claw 52. Multiple degrees of freedom are integrated into the same snap fastening mechanism 20, and only one mechanism is used to complete pressing, rotation correction, and lifting avoidance, eliminating the need for additional correction mechanisms and resulting in a compact structure.

[0057] In one embodiment, the image acquisition device is equipped with a camera 11, which is located above the first surface 3141 with its lens facing downwards onto the first surface 3141. The camera 11 captures high-definition images of the button 53. Alternatively, a light source can be provided to illuminate the first surface 3141, facilitating the camera 11's capture of high-definition images of the button 53 on the first surface 3141.

[0058] Preferably, the sixth driving member 22 is configured as a motor, and the output shaft of the motor is connected to the snap fastener 21 for transmission. The snap fastener 21 can be a rubber sleeve for flexibly pressing onto the button 53 and driving 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, driving the sixth driving member 22 to rise and fall. The eighth driving member 24 includes an eighth cylinder, an eighth slide rail, and an eighth slider. The eighth cylinder is connected to the eighth slider, the eighth slider is slidably connected to the eighth slide rail, and is connected to the seventh driving member 23. The eighth driving member 24 is mounted on the frame 60. Driven by the eighth cylinder, the eighth slider slides along the eighth slide rail, driving the seventh driving member 23 to move horizontally. The sixth driving member 22 and the snap fastener 21 follow the horizontal movement.

[0059] In one embodiment, the feeding mechanism 30 includes a first driving member and a feeding track 31. The output end of the first 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 feed 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, i.e., the button-picking position 314. The first driving member works with the feeding track 31 to achieve automatic and orderly feeding of the buttons 53. The buttons 53 are stably fed along the feeding track 31 to the second end of the feeding track for pickup by the button claw 52. The first 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 push of the upstream buttons 53, the buttons 53 can be fed along the feeding track 31.

[0060] 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, adapting to the conveying 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 using bolts and adjusting grooves.

[0061] Furthermore, 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 track top wall 313 and the track elements on both sides form a closed conveying channel, limiting the up, down, left, and right movement of the button 53, ensuring a regular conveying posture, and preventing the buttons 53 from stacking during the conveying process. The end of the track top wall 313 is provided with a notch 3131, which provides clearance for the pressing action of the fastener 21, allowing the fastener 21 to pass through and press onto the button 53 at the fastening position 314.

[0062] In one embodiment, the snap-on position 314 has an opening, and the feeding mechanism 30 further includes a snap-stopping member 32. The snap-stopping member 32 includes a stop block 321 and a ninth driving member 324. The ninth driving member 324 is connected to the stop block 321 and is used to drive the stop block 321 to move along the width direction of the feeding track 31 to open or close the opening. When the button 53 is fed to the snap-on position 314, the front end of the output end of the feeding track 31 is closed by the stop block 321. At the same time, the bottom wall of the output end of the feeding track 31 has an opening, and the button 53 is supported by the bottom wall (i.e., the first surface 3141). The protrusion 5211 on the snap-on claw 52 can pass through the opening and be inserted into the hole on the button 53. The ninth driving member 324 can be configured as a ninth cylinder. The ninth driving component 324 drives the stop block 321 to move along the width of the track, controlling the opening and closing of the buckle-taking position 314. Closing the opening can prevent the button 53 from disengaging from the buckle-taking position 314. After the buckle claw 52 grabs the button 53, it can open the opening of the buckle-taking position 314, making it convenient for the buckle claw 52 to switch workstations with the button 53.

[0063] 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 button-removing position 314 should also correspondingly increase or decrease. To achieve synchronous adjustment of the width of the feeding track 31 and the size of the button-removing position 314, the feeding mechanism 30 also includes a Y-axis slider 322, a Y-axis slide rail 323, and a transmission structure. The Y-axis slider 322 is slidably connected to the Y-axis slide rail 323 and connected to the ninth driving component 324, i.e., the ninth cylinder is mounted on the Y-axis slider 322. The input end of the transmission structure is connected to the first track element 311, and the output end of the transmission structure is connected to the Y-axis slider 322. When the first track element 311 is adjusted relative to the second track element 312, the transmission structure drives the Y-axis slider 322 to slide along the Y-axis slide rail 323, and drives the stop block 321 to slide, thereby adjusting the distance between the stop block 321 and the opening, i.e., the size of the button-removing position 314. Therefore, by linking the first track element 311 with the Y-axis slider 322 and the stop 321 through the transmission structure, when adjusting the track width to adapt to different button 53 sizes, the stop 321 automatically adjusts the distance between itself and the opening, without the need to adjust the stop 321 separately.

[0064] Specifically, the transmission structure includes a transmission component 325 and a transmission groove 3111 provided on the first track element 311. The transmission groove 3111 is obliquely arranged relative to the length direction of the first track element 311, that is, obliquely arranged relative to the Y direction. The transmission component 325 is provided with a transmission part 3251, which is in transmission engagement with the transmission groove 3111. The transmission part 3251 can be a bearing, which rolls with the transmission groove 3111. When the first track element 311 moves away from the second track element 312, the stop block 321 moves away from the latching position 314. When the first track element 311 moves closer to the second track element 312, the stop block 321 moves closer to the latching position 314. Therefore, the size of the latching position 314 and the width of the feeding track 31 can be synchronously adjusted. It is understandable that the mechanical reversing transmission structure, which uses the inclined transmission groove 3111 to cooperate with the transmission part 3251, can convert the width adjustment displacement of the first track element 311 into the synchronous Y-direction displacement of the stop block 321, so as to realize the mechanical linkage between the track width and the limit position of the stop block 321; the linkage stroke ratio is fixed and the synchronization accuracy is high, and there is no need to adjust the stop block 321 separately when changing the button 53 specification.

[0065] In one embodiment, the fastening mechanism 50 includes a second drive structure mounted on the frame 60 and connected to the fastening arm 51 for driving the fastening arm 51 to move. The fastening claw 52 has a first position and a second position, the first position corresponding to the fastening position 314 and the second position corresponding to the fastening position. Driven by the second drive structure, the fastening arm 51 drives the fastening claw 52 to switch between the first position and the second position. When the fastening claw 52 is in the first position, the fastening claw 52 corresponds to the vertical position of the lens and the docking member 46. When the docking member 46 is connected to the second positioning surface 522, under the drive of the fourth drive member 45, the docking member 46 rotates around the vertical axis and drives the fastening claw 52 to rotate, thereby adjusting the angle of the button 53. When the fastening claw 52 is in the second position, the fastening mechanism 50 delivers the button 53 from the fastening device 100.

[0066] In one embodiment, the second driving structure includes a second driving member 55 and a third driving member 54, the second driving member 55 being connected to the third driving member 54, and the third driving member 54 being connected to the buckle feeding arm 51. Under the drive of the second driving member 55, the third driving member 54 and the buckle feeding arm 51 move linearly in the vertical direction, and the third driving member 54 drives the buckle feeding arm 51 to swing horizontally around the vertical axis.

[0067] Understandably, the second drive component 55 is used to adjust the height of the latch 52, and the third drive component 54 is used to swing the latch 52 horizontally. Through the cooperation of the two sets of drive components, the latch feeding arm 51 and the latch 52 can achieve multi-dimensional movement of vertical lifting and horizontal swinging, thereby completing the multi-station transfer and high-low position adaptation of the button 53.

[0068] Specifically, 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 a second cylinder bracket 551. Driven by the second cylinder 550, the second slider 553 slides along the second slide rail 552, driving the third driving component 54 to move. The third driving component 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, 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.

[0069] In one embodiment, the fastener feeding device 100 further includes an angle adjustment mechanism 40, with the second surface 3142 facing the angle adjustment mechanism 40. 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 drive-connected to the docking member 46. The docking member 46 is engaged / disengaged with the second positioning surface 522. The fourth driving member 45 is equipped with a controller, which is electrically connected to a recognizer. The controller is used to acquire the angle of the button 53 and compare the angle of the button 53 with the set angle of the button 53 to calculate the angle by which the fourth driving member 45 needs to drive the docking member 46 to rotate. For example, if the angle of the button 53 has a 10-degree difference from the set angle of the button 53, then the fourth driving member 45 needs to drive the docking member 46 to rotate by 10 degrees.

[0070] Here, the angle adjustment mechanism 40 is located directly below the snap-on position 314, and the relative positions of the image acquisition device and the angle adjustment mechanism 40 are fixed. When the snap claw 52 is in the first position, the downward horizontal projections of the image acquisition device lens, the snap claw 52, ​​and the docking member 46 coincide, allowing the image acquisition device to capture the image of the button 53 positioned on the snap claw 52, ​​and the docking member 46 to engage upward with the second positioning surface 522. The layered layout of the image acquisition device, the snap claw 52, ​​and the angle adjustment mechanism 40 spatially separates the image acquisition device and the angle adjustment mechanism 40, avoiding mechanical interference.

[0071] 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, which can precisely and quantitatively control the rotation angle, has high angle adjustment accuracy, and can be adjusted in both directions. It is easy to link with the identification mechanism and stably drive the buckle claw 52 to rotate synchronously to correct the posture of the button 53.

[0072] 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, thereby causing the docking member 46 to move synchronously. The fifth driving member is used to drive the docking member 46 to move vertically up and down, thereby realizing the engagement and disengagement of the docking member 46 with the second positioning surface 522 on the latch 52. When engaged, power can be stably transmitted to complete the angle adjustment of the button 53. After disengagement, the docking member 46 avoids the movement space, ensuring that the latch 52 can move smoothly horizontally, effectively avoiding mechanism interference, and allowing the angle adjustment and button delivery processes to cooperate in an orderly manner.

[0073] Specifically, the fifth drive component is configured as a fifth cylinder 41, which is mounted on a mounting plate 43. The mounting plate 43 is mounted on a frame 60. The fourth drive component 45 is mounted on a lifting plate 44. The lifting plate 44 is connected to the fifth cylinder 41 through a connecting plate 42. A slide rail mechanism can be provided between the lifting plate 44 and the mounting plate 43.

[0074] Understandably, by setting up the angle adjustment mechanism 40, after recognizing the corresponding angle of the button 53's marking, the angle of the button 53 can be adjusted to rotate it to the specified angle before it is conveyed to the button attaching machine, thus ensuring that the button 53's marking faces consistently after the button attaching machine finishes attaching the buttons. Furthermore, compared to the top-mounted angle adjustment mechanism design: if the top-mounted structure needs to avoid the button delivery mechanism 50 and adapt to workstation switching, it usually requires an additional horizontal drive mechanism to move the angle adjustment mechanism 40 accordingly or to avoid it. This bottom-mounted design 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. Moreover, by utilizing the unused space below the button claw 52 to arrange the angle adjustment mechanism 40, full use is made of vertical space, eliminating the need to reserve clearance space around the image acquisition area and button delivery area, resulting in a more compact overall structure and a smaller installation space requirement.

[0075] To position and rotate the button 53, at least two protrusions 5211 are provided on the first positioning 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 positioning surface 521. The engagement of the protrusions 5211 with the holes of 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. Simultaneously, the structure is simple, the unloading is smooth, and it is suitable for automated button feeding operations. When button 53 is conveyed to the snap-on position 314 by the feeding mechanism 30, under the drive of the eighth driving member 24, the snap-on member 21 moves horizontally from the initial position to directly above the snap-on position 314, corresponding vertically to the position of button 53. Then, under the drive of the seventh driving member 23, the snap-on member 21 moves vertically downward and presses against button 53. Finally, under the drive of the sixth driving member 22, the snap-on member 21 drives button 53 to rotate. When button 53 rotates to a certain angle, the protrusion 5211 on the snap claw 52 corresponds exactly to the hole on button 53. Thus, after the snap claw 52 rises, the protrusion 5211 on the snap claw 52 inserts into the hole on button 53, and button 53 is successfully retrieved.

[0076] In one embodiment, one of the second positioning 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 positioning surface 522 has two docking grooves 5221 evenly distributed circumferentially along the second positioning 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 of the docking member 46 and the latch 52 can be achieved, effectively preventing rotational slippage and improving angle adjustment accuracy; 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. 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.

[0077] In another embodiment, the second positioning surface 522 is configured as a second friction surface, and the docking member 46 is configured with a first friction surface. The first friction surface abuts against the second friction surface to enable the docking 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.

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.
