[0034] In one embodiment of the present invention, as Figures 1 to 5, as shown in Figures 12 and 19, a keychain automatic assembly machine is provided, which includes a chassis 40, a buckle automatic feeding device 10, a ring automatic feeding device 20, and a keychain automatic assembly device 30. The buckle automatic feeding device 10 is installed on the chassis 40 and is used for automatically feeding the buckle 1. The ring automatic feeding device 20 is installed on the chassis 40 and is used for automatically feeding the ring 2, and the output end of the ring automatic feeding device 20 forms a right angle with the output end of the buckle automatic feeding device 10 and is arranged adjacent to each other. The keychain automatic assembly device 30 includes a ring screwing-in mechanism 31 and a ring opening mechanism 32 installed on the chassis 40. The ring opening mechanism 32 is arranged adjacent to the buckle automatic feeding device 10 and is used for opening the ring 2 conveyed by the ring automatic feeding device 20. The ring screwing-in mechanism 31 is adjacent to the ring opening mechanism 32 and the ring automatic feeding device 20 and is used for positioning the ring 2 and screwing the opened ring 2 onto the buckle conveyed by the buckle automatic feeding device 1. During operation, the buckle automatic feeding device 10 automatically feeds the buckle 1, the ring automatic feeding device 20 automatically feeds the ring 2, then the ring opening mechanism 32 of the keychain automatic assembly device 30 opens the ring 2 conveyed by the ring automatic feeding device 20, and then the ring screwing-in mechanism 31 hangs the opened ring 2 on the buckle 1 conveyed by the buckle automatic feeding device 10 and controls the rotation of the ring 2, so that the ring 2 is screwed onto the buckle 1. In this way, the automatic assembly of the buckle 1 and the ring 2 of the keychain is completed, reducing manual operation, lowering the labor intensity of workers, and greatly improving production efficiency.

[0035] In another embodiment of the present invention, as Figures 1 to 4As shown, the key ring automatic assembly device 30 includes 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 installed on the fixed ring slide 313 through the shaft mounting block 3143, and the central shaft 314 is arranged along the moving direction of the fixed ring slide 313 to be inserted into the ring 2 with the movement of the fixed ring 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 axis 314 and abuts against the other end of the reset spring 316, and the screw-in head 315 is connected to the screw-in motor 317 through the screw-in transmission mechanism 318. 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 opening. When the key ring automatic assembly device 30 provided by the embodiment of the present invention is working, the fixed circle cylinder 312 drives the fixed circle slide plate 313 to move on the fixed circle bracket 311. The movement of the fixed circle slide plate 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 head 315 connected thereto is driven to rotate through the screw-in transmission mechanism 318. 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 operations, reducing the labor intensity of workers, and greatly improving production efficiency.

[0036] 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.

[0037] 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 end of the ring 2, the protrusion 3151 abuts against the end of the ring 2 and drives the ring 2 to rotate until the ring 2 is screwed into the buckle 1 and hooked. In this way, the rotation of the screwing head 315 can be effectively maintained. Moreover, the driving gear 3181, the transmission gear 3182 and the screwing gear 3183 are arranged side by side in total of three gears and are connected within a short distance, improving the efficiency of transmission.

[0038] 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.

[0039] Among them, both the screwing gear 3183 and the screwing head 315 are metal parts, and the two can be fixed by welding.

[0040] 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 with high precision on the fixed ring slide rail and will not deviate in position. Furthermore, since the fixed ring slider 319b is connected to the bottom of the fixed ring slider 319b, it can be ensured 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 accuracy and high working quality.

[0041] In another embodiment of the present invention, as Figure 3 and Figure 7As shown, the central axis 314 is provided with an avoidance notch groove 3141 at the end for inserting into the end of the loop 2. Specifically, the avoidance notch groove 3141 is provided to avoid the loop retaining 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 axis 314 under the retention of the loop retaining bar 2362, so that the loop 2 can be hung on the central axis 314. The structural design is ingenious and the practicability is strong.

[0042] In another embodiment of the present invention, the screwing-in motor 317 is a stepping motor. When the stepping driver receives a pulse signal, it drives the stepping 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. In this way, the control of the rotation angle of the screwing-in head 315 is very precise, and the loop 2 can be effectively screwed into the buckle 1 by controlling the rotation angle of the screwing-in head 315.

[0043] 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 arranged perpendicular to the central axis 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 axis 314, realizing the separation and opening of the loop 2, so as to ensure that the loop 2 can be hung into the buckle 1.

[0044] 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.

[0045] 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 blocked by the central shaft 314, ensuring that the opening ejector pin 323 can normally separate and open the loop 2 hung on the central shaft 314. The structural design is ingenious and has strong practicability.

[0046] In another embodiment of the present invention, as Figures 6 to 8 shown, the loop automatic feeding device 20 includes a loop vibrating feeder 21, a loop flipping mechanism 22, and a loop pushing mechanism 23. The loop vibrating feeder 21 is used to horizontally convey a plurality of loops 2 one by one in one direction. The loop flipping mechanism 22 is connected to the output end of the loop vibrating feeder 21 and is used to flip the horizontally arranged loops 2 conveyed by the loop vibrating feeder 21 to a vertical state. The loop pushing mechanism 23 includes a loop feeding frame 231, a loop feeding cylinder 232, a loop feeding guide rail 233, a loop feeding slider 234, a loop feeding adapter plate 235, a loop feeding head 236, a loop pushing cylinder 237, and a loop pushing rod 238. The loop feeding frame 231 is arranged on the side of the loop vibrating feeder 21. The loop feeding guide rail 233 is horizontally installed on the side of the loop feeding frame 231. The loop feeding slider 234 is slidably engaged with the loop feeding guide rail 233. The loop feeding adapter plate 235 is connected to the loop feeding slider 234. The loop feeding cylinder 232 is installed on the side of the loop feeding frame 231 and its piston rod is connected to the loop feeding adapter plate 235. The loop feeding head 236 and the loop pushing cylinder 237 are both installed on the side of the loop feeding adapter plate 235 and are respectively located on both sides of the loop flipping mechanism 22. The loop pushing rod 238 is connected to the piston rod of the loop pushing cylinder 237 and can push the vertically arranged loop 2 onto the loop feeding head 236 by the drive of the loop pushing cylinder 237.

[0047] More specifically, when the loop automatic feeding device 20 provided by the embodiment of the present invention is working, the loop vibrating feeder 21 conveys a plurality of loops 2 one by one in a direction through vibration. The loops 2 conveyed by the loop vibrating feeder 21 are in a horizontal state onto the loop turning mechanism 22, and then the loop turning mechanism 22 turns the horizontally placed loops 2 into a vertical state. Then, the loop feeding cylinder 232 installed on the loop feeding frame 231 drives the loop feeding adapter plate 235 connected to its piston rod to move, thereby controlling the movement of the loop pushing cylinder 237 installed on the loop feeding adapter plate 235. When the loop feeding adapter plate 235 moves a certain distance, the loop pushing cylinder 237 is activated and drives the loop pushing rod 238 to move. The loop pushing rod 238 pushes the loops 2 that have been turned into a vertical state by the turning arm 224 onto the loop sending head 236. In this way, the automatic feeding of the loops 2 is realized, manual operation is reduced, the labor intensity of workers is lowered, and the production efficiency can be greatly improved.

[0048] In another embodiment of the present invention, as Figures 7 to 8 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 member. Further, a guiding channel 2391 is formed between the U-shaped block 239 and the loop feeding adapter plate 235. 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 vertically placed loops 2 turned by the loop turning mechanism 22 are pushed onto the loop sending head 236 to realize feeding at a precise position.

[0049] In another embodiment of the present invention, as Figures 7 to 8As shown, a ring feeding limit block 2351 is provided on the ring feeding adapter plate 235, and two ring feeding buffers 2352 are provided on the ring feeding frame 231. The two ring feeding buffers 2352 are respectively located in front and behind the moving direction of the ring feeding limit block 2351. Specifically, the ring feeding limit block 2351 moves with the movement of the ring feeding adapter plate 235. When the ring feeding limit block 2351 moves forward or back and forth for a certain distance, it will abut against the ring feeding buffer 2352 which is respectively located in front and behind the moving direction of the ring feeding limit block 2351 and is arranged on the ring feeding frame 231. In this way, the moving distance of the ring feeding limit block 2351 can be limited by the ring feeding buffer 2352, ensuring that the movement of each component (such as the ring pushing cylinder 237) installed on the ring feeding adapter plate 235 will not exceed the set distance, thereby ensuring that the ring pushing cylinder 237 can control the ring pushing rod 238 to accurately push the ring 2, thereby improving the accuracy of the use of the device.

[0050] In another embodiment of the present invention, Figures 7 to 8 As shown, one end of the ring feeding head 236 facing the ring pushing rod 238 is provided with a ring 2 entrance (not shown) directly opposite to the ring pushing rod 238, and one end of the ring feeding head 236 facing away from the ring pushing rod 238 is provided with a ring positioning cavity 2361 communicated with the ring 2 entrance, and the side of the ring positioning cavity 2361 is provided with a ring stop bar 2362. Specifically, the ring 2 in a vertical shape enters the ring 2 entrance through the promotion of the ring pushing rod 238, and enters the ring positioning cavity 2361 through the further promotion of the ring pushing rod 238, and the ring 2 entering the ring positioning cavity 2361 will not automatically fall outside the ring feeding head 236 under the restriction of the ring stop bar 2362, so that the ring 2 located in the ring positioning cavity 2361 after the loading is completed is conducive to the next step of the process, and the structural design is ingenious and practical.

[0051] In another embodiment of the present invention, Figures 7 to 8As shown in the figure, the loop feeding rack 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 near 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. The loop feeding support plate 2312 is arranged perpendicular to the loop feeding support column 2311, providing a support structure for the installation of the loop 2 pushing guide rail, and effectively realizing the setting of the buckle pushing guide rail at the required height position, facilitating the 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 using fasteners or welding.

[0052] In another embodiment of the present invention, as Figures 9 to 10 shown, the loop flipping mechanism 22 includes a cylinder bracket 221, a flipping bracket 222, a flipping cylinder 223, a flipping arm 224, a loop waiting block 225, a waiting block bracket 226, and a flipping transmission mechanism 227. The cylinder bracket 221, the flipping bracket 222, and the waiting block bracket 226 can be arranged on a workbench, and according to the size or requirements of the actual structure, the three are arranged adjacent to each other.

[0053] Further, as Figures 9 to 10 shown, the loop waiting block 225 is installed on the waiting block bracket 226 and is connected to the output end of the loop vibrating feeder 21 to receive the horizontally arranged loop 2 conveyed by the loop vibrating feeder 21. That is, the horizontally arranged loop 2 conveyed by the loop vibrating feeder 21 will enter the loop waiting block 225 and wait to be flipped.

[0054] Further, as Figures 9 to 10 shown, the flipping arm 224 is rotatably connected to the flipping bracket 222, and a loop flipping cavity 2241 is provided at the free end of the flipping arm 224, which can receive the loop 2 on the loop waiting block 225 after flipping relative to the flipping bracket 222. In this way, the flipping arm 224 can be flipped relative to the flipping bracket 222. Then, when the loop 2 is placed in the loop flipping cavity 2241 provided at the free end of the flipping arm 224, the horizontally arranged loop 2 can be flipped to a vertically arranged state.

[0055] Further, as Figures 9 to 10As shown in the figure, the flipping cylinder 223 is installed on the cylinder bracket 221 and connected to the flipping arm 224 through the flipping transmission mechanism 227 to drive the flipping of the flipping arm 224, so that the ring flipping cavity 2241 is directly in front of the ring pushing rod 238. Specifically, the flipping cylinder 223 drives the flipping arm 224 to rotate, and the flipping arm 224 realizes flipping, thereby flipping the ring 2 in the ring flipping cavity 2241 to be directly in front of the ring pushing rod 238, and further driving the ring pushing rod 238 to push the vertically arranged ring 2 into the ring positioning cavity 2361 under the control of the ring pushing cylinder 237, realizing the feeding and positioning of the ring 2.

[0056] 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, so that the rotating shaft 228 can rotate relative to the flipping bracket 222. Then, the flipping arm 224 connected to the rotating shaft can rotate relative to the flipping bracket 222 under the drive of the rotating shaft, thereby driving the flipping of the ring 2 in the ring flipping cavity 2241 on the flipping arm 224. Further, the rotating shaft 228 is connected to the flipping transmission mechanism 227 and the flipping cylinder 223, and can be rotated by the drive of the flipping cylinder 223.

[0057] In another embodiment of the present invention, as Figures 9 to 10 shown, the ring 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 respectively located on both sides of the width direction of the flipping arm 224. Specifically, the two limit baffles 229 are arranged at intervals 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, so as to limit the flipping direction of the flipping arm 224, avoid the left and right swing of the flipping arm 224 from affecting the flipping position of the ring 2 in its ring flipping cavity 2241, and further improve the flipping accuracy of the ring 2.

[0058] In another embodiment of the present invention, as Figures 9 to 10As 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. A rack chute 2274 is provided on the rack mounting block 2273. The rack 2272 is slidably connected within the rack chute 2274. The gear 2271 is mounted at one end of a rotating shaft 228 and is meshed with the rack 2272. Specifically, the rack 2272 is slidably connected within 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, driven by 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, thereby driving the flipping arm 224 to flip. The structural design is reasonable and the practicability is strong.

[0059] In another embodiment of the present invention, as Figure 11 shown, the ring vibration feeder 21 includes a ring storage tray 211, a ring slideway 212 and a ring linear vibrator 213. The ring storage tray 211 is arranged adjacent to the ring linear vibrator 213. The ring slideway 212 is arranged on the top of the ring linear vibrator 213, and one end of the ring slideway 212 is communicated with the ring storage tray 211, and the other end of the ring slideway 212 is connected to the ring waiting material block 225. Specifically, the ring storage tray 211 can store a batch of rings 2. Under the vibration of the ring linear vibrator 213, the rings 2 located in the ring storage tray 211 can move one by one along the ring slideway 212, and then control each ring 2 to move from one end of the ring slideway 212 to the other end, and finally vibrate and convey the rings 2 to the ring waiting material block 225, thereby facilitating the conveyance of the rings 2 into the ring flipping cavity 2241 of the flipping arm 224.

[0060] In another embodiment of the present invention, as Figures 13 to 16As shown in the figure, 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 installed horizontally on the side of the buckle feeding frame 121. The buckle feeding slider 124 is slidably matched 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 installed vertically 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.

[0061] When the buckle automatic feeding device 10 of this embodiment works, the buckle vibrating feeder 11 conveys a number 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 a role in 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 horizontally. Since the buckle feeding adapter 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 moves back and forth horizontally. 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 clamp cylinder 125, realizing automatic feeding, reducing manual operation, reducing the labor intensity of workers, and greatly improving production efficiency.

[0062] 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 connected buckle pushing adapter plate 1281 to move in the horizontal direction. Thus, 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. In this way, with the cooperation of the two-stage cylinders of the buckle pushing cylinder 126 and the buckle feeding cylinder 122, the buckle grasping manipulator 12 can achieve reciprocating movement with a large stroke and reciprocating movement with a small stroke, 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.

[0063] 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 of 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, the movement stroke of the buckle feeding adapter plate 1241 can be made precise 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.

[0064] 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 moving 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.

[0065] 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 fasteners, which is convenient for 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, and then the clip cylinder 125 can be effectively arranged above the buckle vibrating feeder 11, which is convenient for the clip cylinder 125 to grab the buckle 1 on the buckle vibrating feeder 11. The structural design is reasonable and the practicability is strong.

[0066] 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.

Specifically, the buckle feeding support column 1211 can be supported and connected to a platform such as a box body. The buckle feeding support plate 1212 is 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.

[0067] 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 provided at 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 blocking block 1341 located in front of the buckle positioning cavity 1321 is provided at 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 under the blocking of the blocking block 1341 of the buckle blocking moving block 134, the buckle 1 is prevented from falling. In this way, after the positioning of the buckle 1 is completed, the clip 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.

[0068] Further, as Figure 5As shown in the figure, the keychain automatic assembly machine further includes a blanking and recycling channel 50. The blanking and recycling channel 50 is located at the intersection of the buckle automatic feeding device 10, the ring automatic feeding device 20, and the keychain automatic assembly device 30. The buckle 1 after the ring 2 has been hung by the clip cylinder 125 is released and dropped into the blanking and recycling channel 50, and enters the keychain storage box (not shown in the figure) under the guidance of the blanking and recycling channel 50, facilitating the collection of finished products.

[0069] In another embodiment of the present invention, as Figure 18 shown, the buckle waiting material mechanism 13 further includes a buckle blocking slider 135. A buckle blocking chute 1322 is provided on the side of the waiting material positioning block 132. The buckle blocking slider 135 is slidably connected in the buckle blocking chute 1322 and is connected to the piston rod of the buckle blocking cylinder 133. The buckle blocking moving block 134 is connected to the outer side of the buckle blocking slider 135. Specifically, the buckle blocking slider 135 slides in the buckle blocking chute 1322. Through the limitation of the buckle blocking chute 1322, it can be ensured that the buckle blocking slider 135 is not easily offset. In this way, the movement of the buckle blocking moving block 134 driven by the buckle blocking slider 135 is more accurate and does not deviate. Then, the positioning of the buckle 1 in the buckle positioning cavity 1321 is more guaranteed.

[0070] 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. Cooperating with the buckle positioning cavity 1321 to achieve the positioning of the buckle 1 in the horizontal and vertical directions, it is ensured that when the clip cylinder 125 moves above the buckle positioning cavity 1321, it can effectively grab a buckle 1, avoiding the idling of the device and improving the utilization rate of the device.

[0071] 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 adjacent to the buckle linear vibrator 113. The buckle slideway 112 is provided 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 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.

[0072] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
