[0041] Please see Figures 1 to 16As shown, a preferred embodiment of the present invention, a visual threading machine for zipper pulls, includes a frame 1 and a stacking and feeding device 2, a chain clamping device 3, a longitudinal feeding device 4, a transverse feeding device 5, a track device 6, a clamping device 7, a vibratory feeder device 8, a stacking and discharging device 9, and a visual inspection device 10, all mounted on the frame 1. The frame 1 provides support; the stacking and feeding device 2 guides the feeding of the stacked items and detects knotting anomalies; the chain clamping device 3 guides the chain teeth of the stacked items and allows the zipper pull to be threaded onto the stacked items; the longitudinal feeding device 4 places the zipper pull and transports it to the cutting edge position of the stacked items, which is a crucial position for threading the zipper pull; the transverse feeding device 6... Device 5 is used to transfer the pull heads output from track device 6 to the pull head mold of longitudinal feeding device 4; track device 6 is used to store pull heads to ensure that there are enough pull heads available for subsequent threading stations; clamping device 7 is used to clamp the pull heads output from vibratory feeder device 8 one by one onto track device 6, and will pause for a period of time after clamping the pull heads to ensure the stability of vision inspection device 10 when taking pictures; vibratory feeder device 8 is used to output pull heads in an orderly manner; stacking and unloading device 9 is used to provide power for stacking; vision inspection device 10 is used to take pictures and inspect the pull heads, including inspecting the shape, size, color, and logo of the pull tab, as well as the shape, size, and logo of the pull head and the base plate, etc.

[0042] The stacking feeding device 2, chain-connecting device 3, and stacking discharging device 9 are arranged sequentially along a horizontal straight line, enabling the stacks to be straightened and transported flat during use. The longitudinal feeding device 4 is connected to the chain-connecting device 3 to deliver the feeder head to it. The transverse feeding device 5 is connected to the longitudinal feeding device 4, and the longitudinal feeding device 4 is connected to the output end of the track device 6, allowing the transverse feeding device 5 to transfer the feeder head from the track device 6 to the longitudinal feeding device 4. The input end of the track device 6 is connected to the vibrating... The output end of the vibratory feeder 8 is connected to the clamping device 7 to clamp the pull head from the output end of the vibratory feeder 8 and transport it to the track device 6. The clamping device 7 includes a gripper 71 for clamping the pull head from the output end of the vibratory feeder 8 to the input end of the track device 6. The visual inspection device 10 includes two imaging components 101 located on both sides of the gripper 71 for capturing images of the front and back of the clamped pull head. The imaging components 101 include a light source 1011, a lens 1012, and a camera 1013 arranged in sequence.

[0043] In a preferred embodiment of this utility model, a control device 10a is also provided on the frame 1. The stacking feeding device 2, the chain feeding device 3, the longitudinal feeding device 4, the transverse feeding device 5, the track device 6, the clamping device 7, the vibratory feeder feeding device 8, the stacking discharge device 9, and the vision inspection device 10 are all electrically connected to the control device 10a so that the control device 10a can control the operation of the above devices. Specifically, the control device 10a can be a touch screen device.

[0044] In a preferred embodiment of this utility model, such as Figure 2 As shown, the stacking feeding device 2 includes a first base 21 mounted on the frame 1, a vertical support rod 22 mounted on the first base 21, a horizontal support rod 23 connected to the upper part of the vertical support rod 22, a stacking conveying guide wheel 24 rotatably mounted on the vertical support rod 22 and the horizontal support rod 23, and a stacking output guide wheel 25 mounted on the first base 21. The stacking conveying guide wheel 24 and the stacking output guide wheel 25 are both used to guide the stacking.

[0045] A knot detection mechanism 26 is provided in the middle of the vertical support rod 22. The knot detection mechanism 26 includes a first support base 261 on the vertical support rod 22, a swing block 262 swingably mounted on the first support base 261, and a first inductive switch 263 on one side of the swing block 262. The first support base 261 is provided with a packing limit baffle 2611 on the other side corresponding to the swing block 262. A packing conveying channel 264 is formed between the packing limit baffle 2611 and the swing block 262. When the packing feeding device 2 is in use, the packing needs to pass through the packing conveying channel 264. When the conveyed packing is knotted, the swing block 262 will swing under the action of the knotted position. At this time, the first inductive switch 263 can sense the signal, thereby realizing the knot abnormality detection function.

[0046] In a preferred embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the chain-connecting device 3 includes a second base 30 on the frame 1, a lower guide plate 31 on the top of the second base 30, a chain-passing upper plate 32 on the middle of the upper surface of the lower guide plate 31, a first lifting drive cylinder 33, a second lifting drive cylinder 34, a puller head mold 35, a splitting rod 36, a gear mesher seat 37, a second induction switch 38, and a third induction switch 39. The first lifting drive cylinder 33 and the second lifting drive cylinder 34 can both be cylinders.

[0047] The top surface of the lower guide plate 31 has a guide groove 311 formed along the horizontal direction. During use, the chain teeth of the sizing must be placed in the guide groove 311 to guide the chain teeth. One end of the upper guide plate 32 is hinged to the second base 30. When threading the sizing, the upper guide plate 32 can be lifted upwards to facilitate threading. After threading, the upper guide plate 32 is closed downwards to flatten the sizing. The upper guide plate 32 has a sensing opening 321 at the corresponding blade position of the sizing, and a blade sensing plate 322 is installed inside the sensing opening 321. The blade sensing plate 322 is connected to the second sensing switch 38 via a sensing rod 323. In use, when the package is conveyed forward to the position where the blade sensing plate 322 touches the edge of the blade of the package, the blade sensing plate 322 will drive the sensing rod 323 to swing. After detecting the signal of the sensing rod 323, the second sensing switch 38 can control the package discharging device 9 to continue conveying the package forward for a specified length, so that the edge of the blade of the package is exactly at the exit of the lower guide plate 31, thereby facilitating the accurate subsequent insertion of the pull head onto the package.

[0048] The output end of the guide chain groove 311 is sequentially provided with a pull head mold 35, a splitting rod 36, and a gear mesher seat 37 along the conveying direction. A first lifting drive cylinder 33 is located above and connected to the splitting rod 36. When the stacked assembly is conveyed to the correct position, the first lifting drive cylinder 33 drives the splitting rod 36 to descend, thus opening the cutting edge of the stacked assembly and creating the necessary space for the subsequent pull head insertion. A second lifting drive cylinder 34 is located above and connected to the gear mesher seat 37. When the stacked assembly is conveyed to the correct position, the second lifting drive cylinder 34 drives the gear mesher seat 37 to rise. (Vertical feeding device...) Position 4 is located below the upper die 35 of the zipper puller, so that the zipper puller can be conveyed to the upper die 35 of the zipper puller via the longitudinal feeding device 4. A sensing pin 351 is movably installed inside the upper die 35 of the zipper puller, and the lower end of the sensing pin 351 extends to the lower part of the upper die 35 of the zipper puller. The third sensing switch 39 is located above the sensing pin 351. During operation, when the longitudinal feeding device 4 pushes the zipper puller upward into place, the sensing pin 351 will be pushed upward so that the third sensing switch 39 can sense it. At this time, the stacking and discharging device 9 can be controlled to convey the stacking forward a fixed distance and then stop, thereby realizing the installation of the zipper puller onto the stacking.

[0049] In a preferred embodiment of this utility model, such as Figure 5As shown, the stacking and discharging device 9 includes a third base 91 mounted on the frame 1, a drive motor 92 mounted on the third base 91, a stacking conveyor roller 93 connected to the output end of the drive motor 92, a pressing assembly 94 mounted above the stacking conveyor roller 93, and a discharge trough 95 mounted on the output side of the stacking conveyor roller 93; the pressing assembly 94 is rotatably connected to the third base 91. Specifically, the pressing assembly 94 includes a rotating support 941 rotatably connected to the third base 91, a plurality of pulleys 942 rotatably mounted on the rotating support 941, and a pressing belt 943 sleeved on each pulley 942. In practical use, when it is necessary to thread the stacking and discharging device 9, the entire pressing assembly 94 can be lifted upwards to facilitate the threading of the stacking. After the stacking is threaded, the pressing assembly 94 needs to be lowered, and the pressing belt 943 presses the stacking onto the stacking conveyor roller 93. In this way, when the drive motor 92 drives the stacking conveyor roller 93 to rotate, the stacking can be conveyed forward. At the same time, after the pressing assembly 94 is lowered, the rotating support 941 can be locked together with the third base 91 to improve the stability of use.

[0050] In a preferred embodiment of this utility model, such as Figure 7 and Figure 8 As shown, the vibratory feeder feeding device 8 includes a vibratory feeder body 81 mounted on a frame 1. A sequential discharge groove 811 is formed on the vibratory feeder body 81. A discharge limiting plate 812 is provided at the free end of the sequential discharge groove 811. A third lifting drive cylinder 82 is provided above the sequential discharge groove 811. The movable end of the third lifting drive cylinder 82 faces downward and is connected to a sequential discharge stop block 83. In a specific implementation of this utility model, the third lifting drive cylinder 82 can be a cylinder. Two third lifting drive cylinders 82 can be provided above the sequential discharge groove 811, and each third lifting drive cylinder 82 is connected to a sequential discharge stop block 83. When the vibratory feeder body 81 vibrates continuously, the third lifting drive cylinder 82 can drive the sequential discharge stop block 83 to move up and down continuously to ensure that the pull head can discharge materials one by one to the discharge limiting plate 812 in sequence and wait for the clamping device 7 to clamp them.

[0051] The vibratory feeder body 81 is also provided with a discharge gate 813, which is connected to a first telescopic cylinder 84. The first telescopic cylinder 84 can be a pneumatic cylinder. A guide groove 85 is provided below the discharge gate 813, and a first receiving box 86 is provided below the guide groove 85. When the order is completed, if there are still pull heads left in the vibratory feeder body 81, the discharge gate 813 will be opened by the first telescopic cylinder 84, so that the pull heads can automatically slide down along the guide groove 85 into the first receiving box 86. In this way, the operator does not need to manually collect the remaining pull heads, saving time and effort.

[0052] In a preferred embodiment of this utility model, such as Figure 9 As shown, the clamping device 7 further includes a second support base 72 located between the discharge end of the vibratory feeder 8 and the track device 6, a first rodless telescopic cylinder 73 located on the second support base 72, and a fourth lifting drive cylinder 74 located on the first rodless telescopic cylinder 73. The first rodless telescopic cylinder 73 can specifically be a rodless cylinder, and the fourth lifting drive cylinder 74 can specifically be a cylinder. The movable end of the fourth lifting drive cylinder 74 faces downward and is connected to the gripper 71, and the gripper 71 is a finger cylinder. When the clamping device 7 is working, the first rodless telescopic cylinder 73 drives the gripper 71 to move between the discharge end of the vibratory feeder 8 and the input end of the track device 6, and the fourth lifting drive cylinder 74 drives the gripper 71 to move up and down, so as to clamp the pull head from the discharge end of the vibratory feeder 8 and transport the clamped pull head to the track device 6.

[0053] In a preferred embodiment of this utility model, such as Figures 10 to 13 As shown, the track device 6 includes a fourth base 61 mounted on the frame 1, a pull head conveying track 62 mounted vertically on the fourth base 61, a pull tab pusher 63 mounted above the input end of the pull head conveying track 62, a second telescopic cylinder 64 connected to the pull tab pusher 63, a waste material receiving track 65 mounted above the input end of the pull head conveying track 62, a third telescopic cylinder 66 connected to the waste material receiving track 65, a waste material collection box 67 mounted below the output end of the waste material receiving track 66, a second receiving box 68 mounted on one side below the output end of the pull head conveying track 62, and a fourth telescopic cylinder 69 connected to the second receiving box 68. The second telescopic cylinder 64, the third telescopic cylinder 66, and the fourth telescopic cylinder 69 can all be cylinders.

[0054] During operation, when both the pull head and the pull tab are qualified, the second telescopic cylinder 64 drives the pull tab pusher 63 to lift the pull tab on the pull head held by the clamping device 7, making the pull tab 90° with the pull head. This is to open the hook lock inside the pull head, preparing for subsequent assembly and insertion of the pull head, and also facilitating the feeding of the pull head into the pull head conveying track 62. When the pull head or pull tab is unqualified, the third telescopic cylinder 66 drives the waste receiving rail 65 to move below the pull head held by the clamping device 7. In this way, when the clamping device 7 releases the pull head, the unqualified pull head can be conveyed to the waste collection box 67 through the waste receiving rail 65. When the order is completed or a fault is repaired, the fourth telescopic cylinder 69 drives the second receiving box 68 to move below the output end of the pull head conveying track 62, so as to collect the pull heads that have fallen or are left on the pull head conveying track 62, preventing the pull heads from falling onto the machine and causing other malfunctions.

[0055] In a specific implementation of this invention, pull head blocks 621 are horizontally movable on both sides of the output end of the pull head conveying track 62, and a return spring 622 is provided between the pull head blocks 621 and the pull head conveying track 62; a through-beam sensor 623 is also provided at the output end of the pull head conveying track 62; and a pull head pushing assembly 624 is also provided on the back side of the output end of the pull head conveying track 62, specifically including a support slide 624 that is slidably disposed on the back side of the pull head conveying track 62 along the vertical direction. 1. A seventh lifting drive cylinder 6242 and a pull head pusher 6243 hinged to the support slide are provided on the back of the pull head conveying track 62. The pull head pusher 6243 may also be equipped with a torsion spring (not shown). The seventh lifting drive cylinder 6242 is connected to the support slide 6241. The seventh lifting drive cylinder 6242 may be a cylinder. The free end of the pull head pusher 6243 extends into the pull head conveying track 62, and the free end of the pull head pusher 6243 is located above the first pull head at the bottom of the pull head conveying track 62. In operation, the pull head conveyor track 62 of this utility model, with the pull head stopper 621 blocking it, will arrange the pull heads entering the pull head conveyor track 62 one by one upwards. When the through-beam sensor 623 detects that the transverse feeding device 5 is in place, it controls the seventh lifting drive cylinder 6242 to drive the pull head pusher 6243 to push the bottom pull head downwards to the transverse feeding device 5. During this process, the pull head stoppers 621 on both sides will open outwards. After the bottom pull head is pushed out, the pull head stopper 621 will be reset under the action of the return spring 622. At the same time, it controls the seventh lifting drive cylinder 6242 to drive the pull head pusher 6243 to move upwards to above the first pull head at the bottom of the pull head conveyor track 62. During this process, when the pull head pusher 6243 touches the first pull head at the bottom, the pull head pusher 6243 will rotate at a certain angle and continue to move upwards until the pull head pusher 6243 is above the first pull head at the bottom of the pull head conveyor track 62.

[0056] In a preferred embodiment of this utility model, such as Figure 14As shown, the transverse feeding device 5 includes a fifth base 51 mounted on the frame 1, a second rodless telescopic cylinder 52 mounted on the fifth base 51, a rotary cylinder 53 mounted on the second rodless telescopic cylinder 52, and a pull head clamp 54 connected to the rotary cylinder 53. Specifically, the second rodless telescopic cylinder 52 can be a rodless cylinder, and the pull head clamp 54 can be designed with a rotatable clamp at its free end to facilitate subsequent separation of the pull head from the pull head clamp 54. A fourth inductive switch 55 is provided on one side of the fifth base 51. This fourth inductive switch 55 is used to drive the pull head clamp 54 via the second rodless telescopic cylinder 52 to convey the pull head to the longitudinal feeding device 4. When the desired position is reached, a control signal is generated to control the longitudinal feeding device 4 to operate, and at the same time, the second rodless telescopic cylinder 52 is temporarily stopped. When the transverse feeding device 5 is working, the second rodless telescopic cylinder 52 drives the pull head clamp 54 to move between the output end of the track device 6 and the input end of the longitudinal feeding device 4, so as to transfer the pull head output by the track device 6 to the longitudinal feeding device 4. The rotary cylinder 53 drives the pull head clamp 54 to rotate. In specific operation, after the pull head clamp 54 takes the pull head from the output end of the track device 6, the rotary cylinder 53 drives the pull head clamp 54 to rotate 90° so that the pull tab of the pull head faces downward.

[0057] In a preferred embodiment of this utility model, such as Figure 15 and Figure 16 As shown, the longitudinal feeding device 4 includes a third support base 41 mounted on the frame 1, a pull-head die 42 slidably mounted on the third support base 41 in the vertical direction, a hook 43 hinged to one side of the pull-head die 42, a fourth telescopic cylinder 44 located at the lower part of the pull-head die 42 and connected to the hook 43, a fifth lifting drive cylinder 45 mounted on the third support base 41 and connected to the pull-head die 42, and a sixth lifting drive cylinder 46 mounted on the third support base 41 and connected to the pull-head die 42. All cylinders 46 can be pneumatic cylinders; when the longitudinal feeding device 4 is working, the fifth lifting drive cylinder 45 drives the pull head mold 42 to lift and lower to receive the pull head from the transverse feeding device 5. Specifically, when the transverse feeding device 5 delivers the pull head to the top of the pull head mold 42, the fifth lifting drive cylinder 45 drives the pull head mold 42 to rise and receive the pull head; after the pull head enters the pull head mold 42, the fourth telescopic cylinder 44 drives the hook needle 43 to hook the pull tab on the pull head; the sixth lifting drive cylinder 46 drives the pull head mold 42 to lift and lower to deliver the pull head to the chain closing device 3.

[0058] The specific usage method of this utility model's visual threading machine is as follows:

[0059] First, lift the chain-passing upper plate 32 of the chain-connecting device 3 to open the chain-connecting device 3, and lift the pressing component 94 of the stacking and discharging device 9 to open the stacking and discharging device 9; let the stacking pass around the stacking conveying guide wheel 24 and the stacking output guide wheel 25 of the stacking feeding device 2, and let the stacking pass through the knot detection mechanism 26 of the stacking feeding device 2; at the same time, let the stacking pass through the chain-connecting device 3 and the stacking and discharging device 9, and let the chain teeth on the stacking align with the guide groove 311 of the guide lower plate 31; lower the chain-passing upper plate 32 to close the chain-connecting device 3, and let the blade sensing plate 322 of the chain-connecting device 3 insert into the blade of the stacking, and at the same time lower the pressing component 94 to close the stacking and discharging device 9, so as to press down the stacking and ensure that the stacking is flat.

[0060] Second, according to the order requirements, confirm the zipper length, input the required zipper length on the control device 10a, select the corresponding specification for the order, and then start production.

[0061] Third, the drive motor 92 of the control stacking and unloading device 9 drives the stacking conveyor roller 93 to rotate and convey the stacking forward. When the blade sensing plate 322 of the chain closing device 3 touches the edge of the stacking blade, the blade sensing plate 322 will drive the sensing rod 323 to swing. After the second sensing switch 38 detects the signal of the sensing rod 323, it controls the stacking and unloading device 9 to continue to convey the stacking forward for a specified length, so that the edge of the stacking blade is exactly at the exit of the guide chain lower plate 31. The second lifting drive cylinder 34 drives the gear meshing seat 37 to rise, and the first lifting drive cylinder 33 drives the inserting rod 36 to fall, thereby opening the blade of the stacking.

[0062] Fourth, the first rodless telescopic cylinder 73 of the clamping device 7 drives the gripper 71 to move above the output end of the vibratory feeder 8. The fourth lifting drive cylinder 74 drives the gripper 71 to descend and controls the gripper 71 to clamp the pull head. After clamping the pull head, the fourth lifting drive cylinder 74 drives the gripper 71 to rise, and the first rodless telescopic cylinder 73 drives the gripper 71 and the pull head to the position of the vision inspection device 10 (that is, above the track device 6). The vision inspection device 10 takes pictures and inspects the pull head and the pull tab on the pull head.

[0063] When both the pull head and the pull piece are qualified, the second telescopic cylinder 64 drives the pull piece pusher 63 to push the pull piece on the pull head held by the clamping device 7 upward, so that the pull piece and the pull head form a 90° angle; then, the fourth lifting drive cylinder 74 drives the gripper 71 to descend and controls the gripper 71 to release the pull head, so that the pull head enters the pull head conveying track 62 from the upper end of the pull head conveying track 62 of the track device 6, and the pull heads will be arranged one by one upward under the obstruction of the pull head stop 621;

[0064] When the pull head or pull piece is defective, the third telescopic cylinder 66 drives the waste material receiving rail 65 to move to the area below the pull head held by the clamping device 7, and controls the clamping jaws 71 of the clamping device 7 to release the pull head, so that the defective pull head is transported to the waste collection box 67 through the waste material receiving rail 65.

[0065] Fifth, the second rodless telescopic cylinder 52 of the transverse feeding device 5 drives the pull head clamp 54 to move and connect with the output end of the pull head conveying track 62. When the through-beam sensor 623 detects that the pull head clamp 54 of the transverse feeding device 5 is in place, the seventh lifting drive cylinder 6242 is controlled to drive the pull head pusher 6243 to push the lowest pull head down to the pull head clamp 54 of the transverse feeding device 5. Then, the seventh lifting drive cylinder 6242 is controlled to drive the pull head pusher 6243 to move upward to above the first pull head at the bottom of the pull head conveying track 62.

[0066] Sixth, the rotary cylinder 53 of the transverse feeding device 5 drives the pull head clamp 54 and the pull head to rotate 90° together so that the pull tab of the pull head faces downward, and the second rodless telescopic cylinder 52 drives the pull head clamp 54 and the pull head to move directly above the pull head mold 42 of the longitudinal feeding device 4.

[0067] Seventh, when the transverse feeding device 5 delivers the pull head to the top of the pull head mold 42, the fifth lifting drive cylinder 45 drives the pull head mold 42 to rise and take over the pull head. After the pull head enters the pull head mold 42, the fourth telescopic cylinder 44 drives the hook needle 43 to hook the pull tab on the pull head. The second rodless telescopic cylinder 52 of the transverse feeding device 5 drives the pull head clamp 54 to move, so that the pull head clamp 54 separates from the pull head, thereby transferring the pull head to the pull head mold 42. At the same time, the rotary cylinder 53 of the transverse feeding device 5 drives the pull head clamp 54 to rotate and reset.

[0068] Eighth, the sixth lifting drive cylinder 46 drives the pull head mold 42 to rise, so that the pull head abuts the upper pull head mold 35. At this time, the sensing pin 351 will be pushed upward and the third sensing switch 39 will sense it, controlling the stacking and feeding device 9 to convey the stacking forward a fixed distance and then stop, thereby realizing the installation of the pull head onto the stacking. The fourth telescopic cylinder 44 drives the hook 43 to disengage from the pull plate, the sixth lifting drive cylinder 46 drives the pull head mold 42 to descend and reset, the second lifting drive cylinder 34 drives the tooth engagement seat 37 to descend and return to its position, and the first lifting drive cylinder 33 drives the insertion rod 36 to rise and return to its position. After the pull head is inserted, the stacking and feeding device 9 continues to convey the stacking forward.

[0069] Ninth, repeat steps three through eight.

[0070] By adopting the above-described technical solution of this utility model, at least the following beneficial effects are achieved:

[0071] 1. The device 10 can automatically photograph and inspect zipper heads and zipper strips, and can also collect unqualified zipper heads in a unified manner, which can effectively improve the inspection efficiency of zipper heads and ensure product quality.

[0072] 2. The mechanical structure of the entire visual threading machine has been optimized, changing the stacking from the traditional oblique placement to a flat placement. This allows for more maintenance space, facilitating actual maintenance operations, while also making the overall equipment operation more stable and reliable.

[0073] 3. The feed heads can be output one by one in an orderly manner from the vibratory feeder 8, so the operator does not need to frequently clean up the jammed feed heads, which can improve the overall production efficiency.
