[0039] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "mounted", "connected", "connected to", "fixed", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0040] In one embodiment of the present invention, as Figures 1 to 4As shown, a buckle head and ring automatic assembly device 30 is provided, including a ring screwing mechanism 31 and a ring opening mechanism 32 for opening the ring 2. The ring screwing mechanism 31 includes a fixed ring bracket 311, a fixed ring cylinder 312, a fixed ring slide 313, a central shaft 314, a screwing head 315, a return spring 316, a screwing motor 317 and a screwing transmission mechanism 318. The fixed ring slide 313 is slidably connected to the fixed ring bracket 311, and the fixed ring cylinder 312 is installed on the fixed ring bracket 311 and its piston rod is connected to the fixed ring slide 313. The central shaft 314 is slidably mounted on the fixed circle slide 313 through the shaft mounting block 3143, and the central shaft 314 is arranged along the moving direction of the fixed circle slide 313, so as to be inserted into the ring 2 with the movement of the fixed circle slide 313, and the return spring 316 is sleeved outside the central shaft 314, and one end of the return spring 316 abuts against the shaft mounting block 3143. The screw-in head 315 is sleeved outside the central shaft 314 and abuts against the other end of the return spring 316, and the screw-in head 315 is connected to the screw-in motor 317 through the screw-in transmission mechanism 318, and the end of the screw-in head 315 is provided with a protrusion 3151 hung on the buckle head 1 for rotating the ring 2 after the opening is completed. When the automatic assembly device 30 of the buckle head and the ring provided by the embodiment of the present invention is working, the fixed ring cylinder 312 drives the fixed ring slide 313 to move on the fixed ring bracket 311. The movement of the fixed ring slide 313 drives the central shaft 314 and the screw-in motor 317 installed thereon to follow, so that the central shaft 314 can be controlled to penetrate into the ring 2, so as to complete the positioning of the position of the ring 2. Then, the ring opening mechanism 32 divides the ring 2 positioned on the central shaft 314 into circles, so that the ring 2 forms an opening, and after the buckle head 1 is moved into the opening with the cooperation of the external device, the screw-in motor 317 is finally started, and the screw-in transmission mechanism 318 drives the screw-in head 315 connected thereto to rotate. When the screw-in head 315 rotates, the protrusion 3151 set at its end abuts against the ring end of the ring 2, forcing the ring 2 to rotate, so that the entire ring 2 is screwed into and hung on the buckle head 1, completing the automatic assembly of the buckle head 1 and the ring 2, reducing manual operation, reducing the labor intensity of workers, and greatly improving production efficiency.

[0041] In another embodiment of the present invention, Figures 1 to 2 As shown, a fixed circle buffer 3111 is provided on the fixed circle bracket 311 at the rear of the moving direction of the fixed circle slide 313, and the fixed circle buffer 3111 can be connected to the fixed circle bracket 311 by using a central adapter block (not shown). Specifically, the fixed circle buffer 3111 can abut the moving fixed circle slide 313 at a set position, so that the moving stroke of the fixed circle slide 313 can be limited, and the fixed circle slide 313 can be kept moving within the set stroke range without causing mechanical damage to the fixed circle slide 313, thereby improving the accuracy of the movement of the fixed circle slide 313, and making the use of the device more reliable.

[0042] In another embodiment of the present invention, as Figures 1 to 2 shown, the screwing drive mechanism 318 includes a driving gear 3181, a transmission gear 3182, and a screwing gear 3183. The screwing motor 317 is installed on the fixed ring slide plate 313. The driving gear 3181 is connected to the main shaft of the screwing motor 317. The screwing gear 3183 is connected to the screwing head 315 and is coaxially arranged with the screwing head 315. The transmission gear 3182 is rotatably installed on the fixed ring slide plate 313 and is meshed and connected between the driving gear 3181 and the screwing gear 3183. Specifically, after the screwing motor 317 is started, it drives the driving gear 3181 connected thereto to rotate through its main shaft. Under the action of the transmission gear 3182, the screwing gear 3183 is driven to rotate. Since the screwing gear 3183 is connected to the screwing head 315 sleeved outside the central shaft 314, the screwing head 315 can be driven to rotate. In this way, when the protrusion 3151 provided at the end of the screwing head 315 abuts against the ring end of the ring 2, the protrusion 3151 abuts against the ring end of the ring 2 and drives the ring 2 to rotate until the ring 2 is screwed onto the buckle 1 and hooked. This can effectively maintain the rotation of the screwing head 315. Moreover, the driving gear 3181, the transmission gear 3182, and the screwing gear 3183 are arranged side by side in total three gears and are connected within a short distance, improving the efficiency of transmission effectively.

[0043] Furthermore, the transmission gear 3182 can be rotatably installed on the fixed ring bracket 311 through a mounting plate member and a rotating shaft member provided on the mounting plate member.

[0044] Among them, both the screwing gear 3183 and the screwing head 315 are metal parts, and the two can be fixed by welding.

[0045] In another embodiment of the present invention, as Figures 1 to 2 shown, the ring screwing mechanism 31 further includes a fixed ring guide rail 319a and a fixed ring slider 319b. The fixed ring guide rail 319a is installed on the fixed ring bracket 311 and is arranged parallel to the central shaft 314. The fixed ring slider 319b is slidably connected to the fixed ring guide rail 319a and is connected to the bottom of the fixed ring slide plate 313. Specifically, the fixed ring guide rail 319a plays a guiding role. The fixed ring slider 319b slidably connected to the fixed ring guide rail 319a can slide on the fixed ring slide rail with high precision and will not deviate in position. Furthermore, since the fixed ring slider 319b is connected to the bottom of the fixed ring slider 319b, this can ensure that the fixed ring slide plate 313 always moves along the direction of the fixed ring guide rail 319a under the drive of the fixed ring cylinder 312, with high movement precision and high working quality.

[0046] In another embodiment of the present invention, as Figure 3 and Figure 7As shown, a clearance notch groove 3141 is provided at the end of the central shaft 314 for inserting into the end of the loop 2. Specifically, the clearance notch groove 3141 is provided to avoid the loop bar 2362 that protects the loop 2 when inserting the loop 2. In this way, the loop 2 can still be inserted by the end of the central shaft 314 under the retention of the loop bar 2362, so that the loop 2 can be hung on the central shaft 314. The structural design is ingenious and the practicability is strong.

[0047] In another embodiment of the present invention, the screwing-in motor 317 is a stepper motor. When the stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed step angle in the set direction. Its rotation runs step by step at a fixed angle. In this way, the angular displacement can be controlled by controlling the number of pulses, so as to achieve the purpose of accurate positioning; at the same time, the rotation speed and acceleration of the motor can be controlled by controlling the pulse frequency, so as to achieve the purpose of speed regulation. Thus, the control of the rotation angle of the screwing-in head 315 is very precise, and the loop 2 can be effectively screwed onto the buckle 1 by controlling the rotation angle of the screwing-in head 315.

[0048] In another embodiment of the present invention, as Figure 1 and 4 shown, the loop opening mechanism 32 includes a loop separating bracket 321, a loop separating cylinder 322 and an opening ejector pin 323. The loop separating cylinder 322 is installed on the loop separating bracket 321. The piston rod of the loop separating cylinder 322 is perpendicular to the central shaft 314. The opening ejector pin 323 is connected to the piston rod of the loop separating cylinder 322, and the opening ejector pin 323 is coaxially arranged with the piston rod of the loop separating cylinder 322 to open the loop 2 under the drive of the loop separating cylinder 322. Specifically, the loop separating bracket 321 is provided for installing and fixing the loop separating cylinder 322. The loop separating cylinder 322 can drive the opening ejector pin 323 connected thereto to push up the loop 2 hung on the central shaft 314, realizing the loop separation and opening of the loop 2, so as to ensure that the loop 2 can be hung into the buckle 1.

[0049] In another embodiment of the present invention, as Figure 4 shown, the loop opening mechanism 32 further includes a loop separating joint 324. The loop separating joint 324 is connected to the piston rod of the loop separating cylinder 322, and a T-shaped groove 3241 is provided at the end of the loop separating joint 324. A T-shaped block 3231 is provided at one end of the opening ejector pin 323, and the T-shaped block is in fit connection with the T-shaped groove 3241. Specifically, since the loop separating joint 324 is provided with a T-shaped groove 3241 that cooperates with the T-shaped block 3231 on the opening ejector pin 323, the detachable connection between the T-shaped block 3231 and the T-shaped groove 3241 facilitates the connection between the opening ejector pin 323 and the piston rod of the loop separating cylinder 322. The structural design is reasonable and the practicability is strong.

[0050] In another embodiment of the present invention, as Figure 3 shown, a clearance side hole 3142 for avoiding the opening ejector pin 323 is provided on the side of the central shaft 314. Specifically, the provision of the clearance side hole 3142 provides a clearance space for the opening ejector pin 323 that makes a telescopic movement. In this way, when the opening ejector pin extends, it will not be interfered or hindered by the central shaft 314, ensuring that the opening ejector pin 323 can normally open the loops 2 hung on the central shaft 314. The structural design is ingenious and has strong practicability.

[0051] As Figure 5 shown, another embodiment of the present invention provides a buckle and loop automatic assembling machine, including the above-mentioned buckle and loop automatic assembling device 30. Specifically, since the buckle and loop automatic assembling machine uses the above-mentioned buckle and loop automatic assembling device 30, the loop 2 can be automatically hung on the buckle 1 through the buckle and loop automatic assembling device 30. Then, the automatic assembling of the buckle 1 and the loop 2 can be realized, reducing manual operation, lowering the labor intensity of workers, and greatly improving production efficiency.

[0052] Furthermore, as Figure 5 shown, the buckle and loop automatic assembling machine further includes a buckle automatic feeding device 10 for automatically feeding the buckle 1 and a loop automatic feeding device 20 for automatically feeding the loop 2. The buckle automatic feeding device 10 and the loop automatic feeding device 20 are arranged in two directions. In this way, the automatically fed buckle 1 and loop 2 are automatically assembled through the buckle and loop automatic assembling device, realizing the full-automatic assembling of the buckle 1 and the loop 2.

[0053] In another embodiment of the present invention, as Figures 6 to 8As shown in the figure, the ring automatic feeding device 20 includes a ring vibrating feeder 21, a ring flipping mechanism 22, and a ring pushing mechanism 23. The ring vibrating feeder 21 is used to horizontally convey a plurality of rings 2 one by one in a direction. The ring flipping mechanism 22 is connected to the output end of the ring vibrating feeder 21 and is used to flip the horizontally arranged rings 2 conveyed by the ring vibrating feeder 21 to a vertical state. The ring pushing mechanism 23 includes a ring feeding frame 231, a ring feeding cylinder 232, a ring feeding guide rail 233, a ring feeding slider 234, a ring feeding adapter plate 235, a ring feeding head 236, a ring pushing cylinder 237, and a ring pushing rod 238. The ring feeding frame 231 is arranged on the side of the ring vibrating feeder 21. The ring feeding guide rail 233 is horizontally installed on the side of the ring feeding frame 231. The ring feeding slider 234 is slidably engaged with the ring feeding guide rail 233. The ring feeding adapter plate 235 is connected to the ring feeding slider 234. The ring feeding cylinder 232 is installed on the side of the ring feeding frame 231 and its piston rod is connected to the ring feeding adapter plate 235. The ring feeding head 236 and the ring pushing cylinder 237 are both installed on the side of the ring feeding adapter plate 235 and are respectively located on both sides of the ring flipping mechanism 22. The ring pushing rod 238 is connected to the piston rod of the ring pushing cylinder 237 and can push the vertically arranged rings 2 onto the ring feeding head 236 by the drive of the ring pushing cylinder 237.

[0054] More specifically, when the ring automatic feeding device 20 provided by the embodiment of the present invention works, the ring vibrating feeder 21 conveys a plurality of rings 2 one by one in a direction by vibration. The rings 2 conveyed by the ring vibrating feeder 21 are in a horizontal state onto the ring flipping mechanism 22, and then the horizontally arranged rings 2 are flipped to a vertical state by the ring flipping mechanism 22. Then, the ring feeding cylinder 232 installed on the ring feeding frame 231 pushes the ring feeding adapter plate 235 connected to its piston rod to move, thereby controlling the movement of the ring pushing cylinder 237 installed on the ring feeding adapter plate 235. When the ring feeding adapter plate 235 moves a certain distance, the ring pushing cylinder 237 starts and drives the ring pushing rod 238 to move. The ring pushing rod 238 pushes the rings 2 flipped to a vertical state by the flipping arm 224 onto the ring feeding head 236. In this way, the automatic feeding of the rings 2 is realized, manual operation is reduced, the labor intensity of workers is lowered, and the production efficiency can be greatly improved.

[0055] In another embodiment of the present invention, as Figures 7 to 8As shown, a U-shaped block 239 is provided on the side of the loop feeding adapter plate 235. The U-shaped block 239 and the side of the loop feeding adapter plate 235 can be connected by a fastening method. Further, a guiding channel 2391 is formed between the U-shaped block 239 and the loop feeding adapter plate 235, and the loop pushing rod 238 passes through the guiding channel 2391. Specifically, the setting of the U-shaped block 239 can cooperate with the loop feeding adapter plate 235 to form a guiding channel 2391 for the loop pushing rod 238 to pass through, so as to limit the position and moving position of the loop pushing rod 238. In this way, it can be ensured that under the drive of the loop pushing cylinder 237, the loop pushing rod 238 always moves along a predetermined direction, and the loop 2 turned vertically by the loop turning mechanism 22 is pushed onto the loop feeding head 236, realizing feeding at a precise position.

[0056] In another embodiment of the present invention, as Figures 7 to 8 shown, a loop feeding limit block 2351 is provided on the loop feeding adapter plate 235, and two loop feeding buffers 2352 are provided on the loop feeding frame 231. The two loop feeding buffers 2352 are respectively located in front of and behind the moving direction of the loop feeding limit block 2351. Specifically, the loop feeding limit block 2351 moves along with the movement of the loop feeding adapter plate 235. When the loop feeding limit block 2351 moves forward or backward by a certain stroke, it will abut against the loop feeding buffers 2352 provided on the loop feeding frame 231 respectively in front of and behind the moving direction of the loop feeding limit block 2351. In this way, the moving stroke of the loop feeding limit block 2351 can be limited by the loop feeding buffers 2352, ensuring that the movement of each component (such as the loop pushing cylinder 237) installed on the loop feeding adapter plate 235 will not exceed the set stroke, and further ensuring that the loop pushing cylinder 237 can control the loop pushing rod 238 to precisely push the loop 2, improving the accuracy of the device.

[0057] In another embodiment of the present invention, as Figures 7 to 8As shown, one end of the coil feeding head 236 facing the loop pusher 238 is provided with a loop 2 inlet (not shown in the figure) facing the loop pusher 238. One end of the coil feeding head 236 facing away from the loop pusher 238 is provided with a loop positioning cavity 2361 communicating with the loop 2 inlet. A loop stop strip 2362 is provided on the side of the loop positioning cavity 2361. Specifically, the vertically arranged loop 2 is pushed by the loop pusher 238 into the loop 2 inlet, and further pushed by the loop pusher 238 into the loop positioning cavity 2361. The loop 2 entering the loop positioning cavity 2361 will not automatically fall outside the coil feeding head 236 under the restriction of the loop stop strip 2362. In this way, it is beneficial to complete the next process for the loop 2 located in the loop positioning cavity 2361 after feeding. The structure design is ingenious and has strong practicability.

[0058] In another embodiment of the present invention, as Figures 7 to 8 shown, the loop feeding frame 231 includes a loop feeding support column 2311 and a loop feeding support plate 2312. The loop feeding support column 2311 is vertically installed on the side of the loop vibrating feeder 21, and the loop feeding support plate 2312 is horizontally installed on the side of the loop feeding support column 2311. The loop feeding guide rail 233 is horizontally installed on the side of the loop feeding support plate 2312, and the loop feeding cylinder 232 is installed at a position close to the rear end of the loop feeding support plate 2312. Specifically, the loop feeding support column 2311 can be supported and connected to a platform such as a box body. The loop feeding support plate 2312 is perpendicular to the loop feeding support column 2311, providing a support structure for the installation of the loop 2 pusher guide rail, and effectively realizing setting the buckle pusher guide rail at the required height position, facilitating cooperation with the loop vibrating feeder 21. Further, the connection between the loop feeding support column 2311 and the loop feeding support plate 2312 can be achieved by means of fastener connection or welding.

[0059] In another embodiment of the present invention, as Figures 9 to 10 shown, the loop flipping mechanism 22 includes a cylinder support 221, a flipping support 222, a flipping cylinder 223, a flipping arm 224, a loop waiting block 225, a waiting block support 226, and a flipping transmission mechanism 227. The cylinder support 221, the flipping support 222, and the waiting block support 226 can be arranged on a workbench, and according to the actual size or requirement of the structure, the three are arranged adjacent to each other.

[0060] Further, as Figures 9 to 10As shown, the ring waiting material block 225 is installed on the waiting material block bracket 226 and is connected to the output end of the ring vibrating feeder 21 to receive the horizontal ring 2 conveyed by the ring vibrating feeder 21. That is, the horizontal ring 2 conveyed by the ring vibrating feeder 21 will enter the ring waiting material block 225 and wait to be flipped.

[0061] Further, as Figures 9 to 10 shown, the flipping arm 224 is rotatably connected to the flipping bracket 222, and a ring flipping cavity 2241 capable of receiving the ring 2 on the ring waiting material block 225 after flipping relative to the flipping bracket 222 is provided at the free end of the flipping arm 224. In this way, the flipping arm 224 can be flipped relative to the flipping bracket 222. Then, when the ring 2 is placed in the ring flipping cavity 2241 provided at the free end of the flipping arm 224, the horizontal ring 2 can be flipped to a vertical state.

[0062] Further, as Figures 9 to 10 shown, the flipping cylinder 223 is installed on the cylinder bracket 221 and is connected to the flipping arm 224 through a flipping transmission mechanism 227 to drive the flipping arm 224 to flip and make the ring flipping cavity 2241 face the front of the ring pushing rod 238. Specifically, the flipping cylinder 223 drives the flipping arm 224 to rotate, and the flipping arm 224 is flipped. Then, the ring 2 in the ring flipping cavity 2241 is flipped to face the front of the ring pushing rod 238, and further, under the control of the ring pushing cylinder 237, the ring pushing rod 238 is driven to push the vertical ring 2 into the ring positioning cavity 2361 to realize the feeding and positioning of the ring 2.

[0063] In another embodiment of the present invention, as Figures 6 to 7 shown, the ring flipping mechanism 22 further includes a rotating shaft 228. The rotating shaft 228 is connected to the flipping bracket 222 through a bearing, and the rotating shaft 228 is connected to the flipping transmission mechanism 227. The connecting end of the flipping arm 224 is fixedly connected to the rotating shaft 228. Specifically, the rotating shaft 228 is fixed on the flipping bracket 222 through a bearing. In this way, the rotating shaft 228 can rotate relative to the flipping bracket 222. Then, the flipping arm 224 connected to the rotating shaft can be rotated relative to the flipping bracket 222 under the drive of the rotating shaft, and further, the ring 2 in the ring flipping cavity 2241 on the flipping arm 224 can be flipped. Further, the rotating shaft 228, the flipping transmission mechanism 227, and the connecting flipping cylinder 223 are connected, so that the rotating shaft 228 can be rotated by the drive of the flipping cylinder 223.

[0064] In another embodiment of the present invention, as Figures 9 to 10As shown, the loop flipping mechanism 22 further includes a rotating shaft 228 and two limit baffles 229. The two limit baffles 229 are respectively installed on the flipping bracket 222 and are located on both sides of the width direction of the flipping arm 224. Specifically, the two limit baffles 229 are spaced apart on both sides of the width direction of the flipping arm 224, that is, the connection of the two limit baffles 229 is perpendicular to the flipping direction of the flipping arm 224. This can limit the flipping direction of the flipping arm 224 and prevent the flipping arm 224 from swinging left and right, thus affecting the flipping position of the loop 2 in the loop flipping cavity 2241 of the flipping arm 224. Furthermore, the flipping accuracy of the loop 2 can be improved.

[0065] In another embodiment of the present invention, as Figures 9 to 10 shown, the flipping transmission mechanism 227 includes a gear 2271 and a rack 2272. A rack mounting block 2273 is provided on the side of the flipping bracket 222, and a rack chute 2274 is provided on the rack mounting block 2273. The rack 2272 is slidably connected in the rack chute 2274. The gear 2271 is installed at one end of the rotating shaft 228 and is meshed with the rack 2272. Specifically, the rack 2272 is slidably connected in the rack chute 2274. On the one hand, it can protect the rack 2272. Most importantly, it can guide the movement position of the rack 2272. That is, under the drive of the piston rod of the flipping drive, the rack 2272 can always move back and forth along the direction of the rack chute 2274, ensuring the stability and reliability of the movement direction. In this way, the moving rack 2272 can drive the gear 2271 meshed with it to rotate, and the gear 2271 drives the rotating shaft 228 connected to it to rotate, and then drives the flipping arm 224 to flip. The structural design is reasonable and the practicability is strong.

[0066] In another embodiment of the present invention, as Figure 11 shown, the loop vibrating feeder 21 includes a loop storage tray 211, a loop slideway 212 and a loop linear vibrator 213. The loop storage tray 211 is adjacent to the loop linear vibrator 213. The loop slideway 212 is arranged on the top of the loop linear vibrator 213, and one end of the loop slideway 212 is communicated with the loop storage tray 211, and the other end of the loop slideway 212 is connected to the loop waiting block 225. Specifically, the loop storage tray 211 can store a batch of loops 2. Under the vibration of the loop linear vibrator 213, the loops 2 in the loop storage tray 211 can move one by one along the loop slideway 212, and then control each loop 2 to move from one end of the loop slideway 212 to the other end, and finally vibrate and convey the loop 2 to the loop waiting block 225, which is convenient to convey the loop 2 into the loop flipping cavity 2241 of the flipping arm 224.

[0067] In another embodiment of the present invention, as Figures 13 to 16As shown, the buckle automatic feeding device 10 includes a buckle vibrating feeder 11 and a buckle grasping manipulator 12. The buckle grasping manipulator 12 includes a buckle feeding frame 121, a buckle feeding cylinder 122, a buckle feeding guide rail 123, a buckle feeding slider 124 and a clamp cylinder 125. The buckle feeding frame 121 is arranged on the side of the buckle vibrating feeder 11. The buckle feeding guide rail 123 is horizontally installed on the side of the buckle feeding frame 121. The buckle feeding slider 124 is slidably engaged with the buckle feeding guide rail 123. The buckle feeding cylinder 122 is connected to the buckle feeding frame 121, and the piston rod of the buckle feeding cylinder 122 is connected to the buckle feeding slider 124 through a buckle feeding adapter plate 1241. The clamp cylinder 125 is vertically installed on the side of the buckle feeding adapter plate 1241 and above the buckle vibrating feeder 11, and the jaws of the clamp cylinder 125 are arranged downward for grasping the buckle 1 conveyed by the buckle vibrating feeder 11 to a set position.

[0068] When the buckle automatic feeding device 10 of this embodiment works, the buckle vibrating feeder 11 conveys a plurality of buckles 1 one by one along a direction by vibration, and then the buckle grasping manipulator 12 grasps the buckle 1 conveyed by the buckle vibrating feeder 11 to a set position, thus completing the automatic feeding of the buckle 1. Among them, the specific work of the buckle grasping manipulator 12 is that the buckle feeding frame 121 plays the role of installing and fixing each component. After starting the buckle feeding cylinder 122, the piston rod of the buckle feeding cylinder 122 drives the buckle feeding adapter plate 1241 connected to it to move along the horizontal direction. Since the buckle feeding adapter plate is connected to the buckle feeding slider 124, and the buckle feeding slider 124 is slidably connected to the buckle feeding guide rail 123 installed on the buckle feeding frame 121, it is ensured that under the guidance of the buckle feeding guide rail 123, the buckle feeding adapter plate 1241 always reciprocates along the horizontal direction. Then, the clamp cylinder 125 connected to the buckle feeding adapter plate 1241 also realizes reciprocating movement. And the clamp cylinder 125 is located above the buckle vibrating feeder 11. In this way, the buckle 1 on the buckle vibrating feeder 11 can be grasped by the buckle vibrating feeder 11, realizing automatic feeding, reducing manual operation, reducing the labor intensity of workers, and greatly improving production efficiency.

[0069] In another embodiment of the present invention, as Figures 14 to 16As shown, the buckle grasping manipulator 12 further includes a buckle pushing cylinder 126, a buckle pushing guide rail 127 and a buckle pushing slider 128. The buckle pushing guide rail 127 is horizontally installed on the side of the buckle feeding frame 121. The buckle pushing slider 128 is slidably engaged with the buckle pushing guide rail 127. A buckle pushing adapter plate 1281 is connected to the buckle pushing slider 128. The buckle feeding guide rail 123 is horizontally installed on the side of the buckle pushing adapter plate 1281. The buckle feeding cylinder 122 is connected to the buckle pushing adapter plate 1281. The buckle pushing cylinder 126 is installed on the buckle feeding frame 121, and the piston rod of the buckle pushing cylinder 126 is connected to the buckle pushing adapter plate 1281. Specifically, after the buckle pushing cylinder 126 is started, its piston rod pushes the buckle pushing adapter plate 1281 connected thereto to move in the horizontal direction. In this way, both the buckle feeding cylinder 122 and the buckle feeding guide rail 123 installed on the buckle pushing adapter plate 1281 achieve horizontal movement. Moreover, the buckle pushing adapter plate 1281 is connected to the buckle pushing slider 128 slidably connected to the buckle pushing guide rail 127. In this way, under the guidance of the buckle pushing guide rail 127, it can always achieve reciprocating movement in the horizontal direction. Thus, the buckle grasping manipulator 12 can achieve reciprocating movement with a large stroke and reciprocating movement with a small stroke under the cooperation of the two-stage cylinders of the buckle pushing cylinder 126 and the buckle feeding cylinder 122, and can precisely control the displacement of the clip cylinder 125. Furthermore, it can reliably grasp the buckle 1 located on the buckle vibrating feeder 11 through the clip cylinder 125, realizing precise automatic feeding of the buckle 1. The structural design is reasonable and the practicability is strong.

[0070] In another embodiment of the present invention, as Figures 14 to 16 shown, a buckle feeding limit block 1242 is provided on the buckle feeding adapter plate 1241, and two buckle feeding buffers 1282 are provided on the buckle pushing adapter plate 1281. The two buckle feeding buffers 1282 are respectively located in front of and behind the moving direction of the buckle feeding limit block 1242. Specifically, the buckle feeding limit block 1242 and the buckle feeding adapter plate 1241 can be an integral structure, or the buckle feeding limit block 1242 can also be fixed to the buckle feeding adapter plate 1241 by fasteners. The buckle feeding adapter plate 1241 realizes reciprocating movement in the horizontal direction under the control of the buckle feeding cylinder 122. During the movement of the buckle feeding adapter plate 1241, the farthest strokes in front of and behind it can be limited by the buckle feeding buffers 1282. In this way, it can avoid the movement stroke of the buckle feeding adapter plate 1241 being precise and not interfering with other components, reducing conflicts or collisions between components due to the execution of actions, and improving the reliability and safety of the device operation.

[0071] In another embodiment of the present invention, as Figures 14 to 16As shown, there is a buckle pushing limit block 1283 on the buckle pushing transfer plate 1281, and two buckle pushing buffers 1213 are arranged on the buckle feeding rack 121. The two buckle pushing buffers 1213 are respectively located behind the moving direction of the buckle pushing limit block 1283 and in front of the moving direction of the buckle pushing transfer plate 1281. Specifically, the buckle pushing limit block 1283 and the buckle pushing transfer plate 1281 can be of an integral structure, or the buckle pushing limit block 1283 can also be fixed to the buckle pushing transfer plate 1281 by fasteners. The buckle pushing transfer plate 1281 realizes reciprocating movement in the horizontal direction under the control of the buckle pushing cylinder 126. During the movement of the buckle pushing transfer plate 1281, the farthest strokes in its front and rear can be limited by the buckle pushing buffers 1213, so that the movement stroke of the buckle pushing transfer plate 1281 can be accurate and it will not interfere with other components, reducing the conflict or collision between components due to the execution of actions, and improving the reliability and safety of the device operation.

[0072] In another embodiment of the present invention, as Figures 14 to 16 shown, a cylinder fixing block 1251 perpendicular to the buckle pushing transfer plate 1281 is arranged on the front end side of the buckle pushing transfer plate 1281, and the clip cylinder 125 is installed on the cylinder fixing block 1251. Specifically, the cylinder fixing block 1251 is connected to the front end side of the buckle pushing transfer plate 1281 by means of fasteners, which facilitates the installation and disassembly of the cylinder fixing block 1251. The setting of the cylinder fixing block 1251 provides a support structure for the installation of the cylinder fixing block 1251, that is, the clip cylinder 125 can be installed at the extended position of the buckle pushing transfer plate 1281, so as to effectively make the clip cylinder 125 arranged above the buckle vibrating feeder 11, which is convenient for the clip cylinder 125 to grab the buckles 1 on the buckle vibrating feeder 11. The structure design is reasonable and the practicability is strong.

[0073] In another embodiment of the present invention, as Figures 14 to 16As shown in the figure, the buckle feeding rack 121 includes a buckle feeding support column 1211 and a buckle feeding support plate 1212. The buckle feeding support column 1211 is installed vertically on the side of the buckle vibrating feeder 11, the buckle feeding support plate 1212 is installed horizontally on the side of the buckle feeding support column 1211, and the buckle pushing guide rail 127 is installed horizontally on the side of the buckle feeding support plate 1212. Specifically, the buckle feeding support column 1211 can be supported and connected to a platform such as a box. The buckle feeding support plate 1212 is arranged perpendicular to the buckle feeding support column 1211, providing a support structure for the installation of the buckle pushing guide rail 127, and effectively setting the buckle pushing guide rail 127 at the required height position, facilitating the cooperation with the buckle vibrating feeder 11. Further, the connection between the buckle feeding support column 1211 and the buckle feeding support plate 1212 can be achieved by using fasteners or welding.

[0074] In another embodiment of the present invention, as Figure 13 and Figure 18 shown, the automatic buckle feeding device 10 includes a buckle waiting material mechanism 13. The buckle waiting material mechanism 13 includes a waiting material base 131, a waiting material positioning block 132, a buckle blocking cylinder 133 and a buckle blocking moving block 134. The waiting material base 131 is arranged in front of the buckle vibrating feeder 11. The waiting material positioning block 132 is installed on the top of the waiting material base 131, and a buckle positioning cavity 1321 for docking with the buckle vibrating feeder 11 is arranged on the top of the waiting material positioning block 132. The buckle blocking cylinder 133 is installed on the side of the waiting material base 131. The buckle blocking moving block 134 is connected to the piston rod of the buckle blocking cylinder 133 and is slidably connected to the waiting material positioning block 132, and a material blocking block 1341 located in front of the buckle positioning cavity 1321 is arranged on the top of the buckle blocking moving block 134. Specifically, the setting of the waiting material base 131 can provide installation for the waiting material positioning block 132 and the buckle blocking cylinder 133. The buckle blocking cylinder 133 controls the up and down movement of the buckle blocking moving block 134. Under the control of the buckle blocking cylinder 133, the buckle blocking moving block 134 can be positioned in front of the buckle vibrating feeder 11. Then, when the buckle 1 is conveyed to its front by the buckle vibrating feeder 11, it can enter the buckle positioning cavity 1321 of the waiting material positioning block 132, and is blocked by the material blocking block 1341 of the buckle blocking moving block 134 to prevent the buckle 1 from falling. In this way, after the positioning of the buckle 1 is completed, the clamp cylinder 125 of the buckle grasping manipulator 12 can accurately move above the buckle 1 in the buckle positioning cavity 1321 under the control of the buckle feeding cylinder 122 and / or the buckle pushing cylinder 126 to grasp the buckle 1, realizing more accurate feeding of the buckle 1.

[0075] In another embodiment of the present invention, as Figure 18As shown, the buckle waiting material mechanism 13 further includes a buckle slider 135. A buckle chute 1322 is provided on the side of the waiting material positioning block 132. The buckle slider 135 is slidably connected in the buckle chute 1322 and is connected to the piston rod of the buckle cylinder 133. The buckle moving block 134 is connected to the outer side of the buckle slider 135. Specifically, the buckle slider 135 slides in the buckle chute 1322. Through the limitation of the buckle chute 1322, it can be ensured that the buckle slider 135 is not easily offset. In this way, the movement of the buckle moving block 134 driven by the buckle slider 135 is more accurate and will not be offset. Then, the positioning of the buckle 1 in the buckle positioning cavity 1321 is more guaranteed.

[0076] In another embodiment of the present invention, a limiting piece (not shown in the figure) for restricting the position of the buckle 1 and extending towards the buckle positioning cavity 1321 is provided on the top of the material blocking block 1341. Specifically, the setting of the limiting piece can ensure that the buckle 1 located in the buckle positioning cavity 1321 will not bounce or jump out from above the buckle positioning cavity 1321, and cooperate with the buckle positioning cavity 1321 to realize the positioning of the buckle 1 in the horizontal and vertical directions, ensuring that the clip cylinder 125 can effectively grab a buckle 1 when moving above the buckle positioning cavity 1321, avoiding the idling of the device and improving the utilization rate of the device.

[0077] In another embodiment of the present invention, as Figure 13 and Figure 17 shown, the buckle vibrating feeder 11 includes a buckle storage tray 111, a buckle slideway 112 and a buckle linear vibrator 113. The buckle storage tray 111 is arranged adjacent to the buckle linear vibrator 113. The buckle slideway 112 is arranged on the top of the buckle linear vibrator 113, and one end of the buckle slideway 112 is communicated with the buckle storage tray 111, and the other end of the buckle slideway 112 is communicated with the buckle positioning cavity 1321. Specifically, the buckle storage tray 111 can store a batch of buckles 1. Under the vibration of the buckle linear vibrator 113, the buckles 1 located in the buckle storage tray 111 can move one by one along the buckle slideway 112, and then control each buckle 1 to move from one end of the buckle slideway 112 to the other end, and finally vibrate and convey the buckle 1 into the buckle positioning cavity 1321, facilitating the clip cylinder 125 to clamp it.

[0078] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
