Description

Technical Field

[0001] This invention relates to the field of jewelry spring clasp processing equipment, and more particularly to an automatic jewelry spring clasp assembly machine. Background Technology

[0002] In today's society, jewelry has become an indispensable part of human life. Most non-elastic chain jewelry, such as necklaces, bracelets, waist chains, and decorative belts, have various types of clasps at both ends for easy use. Among them, spring clasps are the most common and stable connecting clasps. They control the opening and closing of the clasp through the cooperation of a lever and a spring. The opening and closing action is passive, requiring external force to move the lever to compress the spring, while closing is driven by the spring actively rebounding. Therefore, once the jewelry is connected and the spring clasp is locked, the connection is not easy to slip off.

[0003] Existing spring buckles mainly consist of three parts: the buckle body, the spring, and the lever. The buckle body is a hollow tubular shape with an arc-shaped opening on one side. A slotted through-hole is formed on the outer wall of the buckle body, connecting to the interior. During assembly, the spring is first installed inside the buckle body, and then the lever is installed through the slotted through-hole, with one end abutting against the spring and the other end against the end of the buckle body. Under normal conditions, the lever, under the spring's elastic force, abuts against the buckle body, completing the closure. Traditionally, spring buckle assembly is done manually by workers, or the spring is installed into the buckle body using equipment, followed by manual installation of the lever. However, this manual assembly method is inefficient and costly. Furthermore, some spring buckles are small, making assembly difficult and prone to low precision, thus reducing product yield.

[0045] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0046] like Figures 1 to 4 As shown, the present invention includes an assembly turntable 6; the outer side of the assembly turntable 6 is sequentially provided with a buckle body feeding device 1, a spring feeding device 2, a paddle punching feeding device 3, a good product inspection device 4, and a spring buckle unloading device 5, all adapted to the assembly turntable 6 along the assembly process of the spring buckle; the assembly turntable 6 is used to fix or release the buckle body 91, and to drive the buckle body 91 to move sequentially along the assembly process of the spring buckle; the buckle body feeding device 1 is used to transport the buckle body 91 and push the buckle body 91 to the assembly turntable 6; the spring... Spring feeding device 2 is used to transport springs and push them into the inside of buckle body 91; pawl punching feeding device 3 is used to punch pawl strip 7 into pawl 92 and assemble pawl 92 into buckle body 91; good product detection device 4 is used to actuate the pawl 92 of the spring buckle and define the current spring buckle as good or bad based on the actuation result; spring buckle unloading device 5 is adapted to good product detection device 4 and is used to classify and receive good or bad spring buckles.

[0047] This application describes the automated assembly of spring clasps, thereby reducing labor costs and improving assembly efficiency. Spring clasps are common connectors in this technical field, mainly used to detachably connect the two ends of jewelry chains (such as necklaces and bracelets) for wearing. Before describing this application, the components of a spring clasp are briefly introduced, mainly including a clasp body 91, a spring, and a lever 92. The clasp body 91 is an open annular structure with a hollow interior for housing the spring and lever 92. A slotted through hole is provided on the outer wall of the clasp body 91 to facilitate the lever 92's extension and operation by the user. The assembly process involves first fixing the clasp body 91, then installing the spring inside the clasp body 91, and then installing the lever 92 on the clasp body 91. One end of the lever 92 abuts against the spring, and the other end abuts against the clasp body 91. The spring clasp is opened or closed by compressing the spring.

[0048] In this invention, the buckle feeding device 1 includes a buckle vibratory feeder 11, a buckle downward guide rail assembly 12, a buckle translation mechanism 13, and a buckle feeding transmission assembly 14. The buckle vibratory feeder 11 holds the buckles and arranges them sequentially before moving them out. The buckle downward guide rail assembly 12 is located outside the buckle vibratory feeder 11 and is vertically arranged. The top end of the buckle downward guide rail assembly 12 is connected to the outlet of the buckle vibratory feeder 11, and the buckle downward guide rail assembly 12 guides the buckles moved out of the buckle vibratory feeder 11 downwards. The buckle translation mechanism 13 includes components connected to the buckle downward guide rail assembly. The buckle body feeding and carrying assembly 131 is adapted to the buckle body 12. The buckle body feeding and carrying assembly 131 is located below the buckle body lowering guide rail assembly 12 and is horizontally arranged along the X direction. The buckle body feeding and carrying assembly 131 is adapted to the buckle body translation and pushing assembly 132. The buckle body translation and pushing assembly 132 is used to push the buckle body placed on the buckle body feeding and carrying assembly 131 to move along the X direction. The buckle body feeding transmission assembly 14 drives the buckle body translation and pushing assembly 132 to the external power device 8. The buckle body feeding transmission assembly 14 is used to push the buckle body translation and pushing assembly 132 to move along the X direction.

[0049] After the buckle body is removed from the buckle body vibratory plate 11, it is guided by the buckle body downward guide rail assembly 12 to move vertically to the buckle body loading and bearing assembly 131, and then pushed onto the assembly turntable 6 by the buckle body translation and pushing assembly 132. The buckle body downward guide rail assembly 12 includes a cylindrical buckle body downward guide rail 121, with a buckle body downward positioning piece 122 at its bottom end. The buckle body downward positioning piece 122 is positioned along the X-direction towards the side closest to the buckle body translation and pushing assembly 132. During the downward movement of the buckle body along the buckle body downward guide rail 121, the buckle body downward positioning piece 122 is used to position the opening of the buckle body outward along the X-direction to meet subsequent assembly requirements.

[0050] In this invention, the buckle body translation mechanism 13 includes a buckle body translation mounting base 133, on which a buckle body translation pushing component 132 is slidably disposed; the buckle body loading and bearing component 131 includes a buckle body downward moving connecting base 1311 mounted on the buckle body translation mounting base 133, and the buckle body downward moving connecting base 1311 is fixedly connected to the buckle body downward moving guide rail component 12; a buckle body loading carrier plate 1312 connected to the buckle body translation mounting base 133 is disposed below the buckle body downward moving connecting base 1311, the buckle body loading carrier plate 1312 is positioned corresponding to the buckle body downward moving guide rail component 12, and a buckle body loading avoidance groove 1313 is provided on the buckle body loading carrier plate 1312 for avoiding the buckle body 91.

[0051] The buckle body translation and pushing assembly 132 includes a buckle body translation and pushing seat 1321, which has a U-shaped structure and is located on the outside of the buckle body translation mounting seat 133. A buckle body translation sliding rod is installed on the buckle body translation and pushing seat 1321 and passes through the buckle body translation mounting seat 133. A buckle body feeding return spring (also hidden in the figure) is sleeved on the outside of the buckle body translation sliding rod (hidden in the figure). One end of the buckle body feeding return spring abuts against the buckle body translation mounting seat 133, and the other end of the buckle body feeding return spring abuts against the buckle body translation and pushing seat 1321. A buckle body translation push plate 1322 arranged along the X direction is installed on one end of the buckle body translation and pushing seat 1321, and the other end of the buckle body translation and pushing seat 1321 abuts against the buckle body feeding transmission assembly 14.

[0052] In this invention, when the buckle body translation pusher 1321 pushes the buckle body 91, its power is provided by an external power device 8. The buckle body loading transmission assembly 14 pushes the buckle body translation pusher 1321, causing it to drive the buckle body translation pusher 1322 to move towards the side closer to the assembly turntable 6, pushing the buckle body 91 onto the assembly turntable 6. At this time, the buckle body loading reset spring is compressed. When it is necessary to reset and perform the next pushing action, the buckle body translation pusher 1321 is pushed to move in the opposite direction by the elastic force of the buckle body loading reset spring, so that it returns to the initial position and completes the reset.

[0053] To prevent displacement of the buckle 91 when it is pushed by the buckle translation push plate 1322, a buckle pushing notch 1323 for accommodating the buckle 91 is provided on the buckle translation push plate 1322. The buckle pushing notch 1323 is arc-shaped and is located below the buckle lower guide rail assembly 12. The arc-shaped buckle pushing notch 1323 facilitates close contact with the outer wall of the buckle 91, satisfying the pushing requirement. At the same time, during pushing, it is limited on both sides to prevent the buckle 91 from sliding out of the buckle loading carrier plate 1312.

[0054] In this invention, to ensure continuous feeding of the buckle body 91, the buckle body translation mechanism 13 further includes a buckle body distribution plate 134 mounted on the buckle body translation push seat 1321. The buckle body distribution plate 134 is disposed on the outside of the buckle body downward guide rail assembly 12. The buckle body distribution plate 134 has a buckle body upper limit protrusion 1341 and a buckle body lower limit protrusion 1342 protruding outwards on the side facing the buckle body downward guide rail assembly 12. The lower limit protrusion 1342 is set along the X direction; vertically, there is a gap between the upper limit protrusion 1341 and the lower limit protrusion 1342 of the buckle body material distribution. The upper limit protrusion 1341 of the buckle body material distribution is set above the buckle body push notch 1323 and close to the buckle body downward guide rail assembly 12. The lower limit protrusion 1342 of the buckle body material distribution is set along the X direction outside the upper limit protrusion 1341 of the buckle body material distribution and close to the buckle body translation push plate 1322.

[0055] As the buckle body 91 falls along the buckle body downward guide rail 121, it is first blocked by the upper limit protrusion 1341 of the buckle body material distribution. Then, the buckle body material distribution plate 134 moves along the X direction towards the side closer to the assembly turntable 6 with the buckle body translation push seat 1321. During the movement, the upper limit protrusion 1341 of the buckle body material distribution gradually separates from the buckle body 91, and the buckle body 91 gradually falls and contacts the lower limit protrusion 1342 of the buckle body material distribution. Therefore, the buckle body 91 is then blocked by the lower limit protrusion 1342 of the buckle body material distribution. When the buckle body distribution plate 134 moves in the opposite direction with the buckle body translation push seat 1321, the buckle body 91 gradually separates from the buckle body distribution lower limit protrusion 1342 and then falls freely onto the buckle body loading plate 1312. During this process, the buckle body distribution upper limit protrusion 1341 simultaneously continues to block the next buckle body 91 that falls on it, preventing it from falling with it. This achieves the goal of placing each buckle body 91 individually on each assembly station 611 of the assembly turntable 6, realizing continuous feeding.

[0056] It should be noted that the buckle body lower positioning piece 122 is positioned close to the upper limit protrusion 1341 of the buckle body material distribution. As the buckle body 91 falls onto the upper limit protrusion 1341 of the buckle body material distribution and gradually separates from it, the buckle body 91 rotates around the axis of the buckle body lower guide rail 121 due to the movement of the upper limit protrusion 1341 of the buckle body material distribution. When its opening moves to the buckle body lower positioning piece 122, under the action of its own gravity, the opening of the buckle body 91 contacts the buckle body lower positioning piece 122. The buckle body lower positioning piece 122 restricts the rotation of the buckle body 91 and at the same time limits the orientation of the opening of the buckle body 91. Thus, the opening of the buckle body 91 is set to a uniform orientation.

[0057] like Figure 1 , Figure 2 , Figures 5 to 8As shown in the figure, in this invention, the spring feeding device 2 includes a spring vibratory feeder 21, a spring reversing mechanism 22, a spring pushing mechanism 23, a spring reversing transmission assembly 24, and a spring pushing transmission assembly 25; wherein, the spring vibratory feeder 21 is used to hold springs and arrange them in sequence before moving them out; the spring reversing mechanism 22 includes a spring guide seat 221 and a spring reversing member 222 adapted thereto; the spring guide seat 221 has a spring receiving through hole 2211 for receiving springs, and the spring reversing member 222 has a spring guiding through hole 2221 for accommodating springs, and the spring reversing member 222 is vertically arranged and can reciprocate around its own axis; the spring pushing mechanism 23 is arranged along the Y direction outside the spring guide seat 221. On the side, the spring pushing mechanism 23 includes a spring pushing member 231. A spring pushing through hole 2212 adapted to the spring pushing member is provided on the spring through seat 221. The spring pushing member 231 is used to push the spring located in the spring through hole 2221 out to the side closer to the assembly turntable 6 after passing through the spring pushing through hole 2212. The spring reversing transmission assembly 24 drives the spring reversing mechanism 22 to the external power device 8. The spring reversing transmission assembly 24 is used to drive the spring reversing member 222 to reciprocate around its own axis. The spring pushing transmission assembly 25 drives the spring pushing mechanism 23 to the external power device 8. The spring pushing transmission assembly 25 is used to drive the spring pushing member 231 to reciprocate along the Y direction.

[0058] The spring reversing mechanism 22 also includes a spring feeding rack 223, a spring guide seat 221 mounted on the spring feeding rack 223, and a spring receiving through hole 2211 facing the side closer to the spring vibrating plate 21. The spring reversing member 222 is vertically rotatably mounted on the spring feeding rack 223. The spring guide seat 221 has a spring reversing cavity 2213 for accommodating the bottom end of the spring reversing member 222. The spring receiving through hole 2211 and the spring pushing through hole 2212 are both connected to the spring reversing cavity 2213. When the spring reversing member 222 rotates, the spring guiding through hole 2221 is adjusted to be connected to the spring receiving through hole 2211 or to the spring pushing through hole 2212.

[0059] By adjusting the connection between the spring through hole 2221 and the spring receiving through hole 2211, the spring can be transferred through the spring receiving through hole 2211 into the spring through hole 2221. By adjusting the connection between the spring through hole 2221 and the spring pushing through hole 2212, the spring pushing member 231 can pass through the spring pushing through hole 2212 to push the spring out of the spring through hole 2221. The spring reversing member 222 is provided with a reversing limiting protrusion 2222 that is adapted to the assembly turntable 6. When the spring reversing member 222 rotates around its own axis, the reversing limiting protrusion 2222 abuts against the assembly turntable 6, limiting the rotation of the spring reversing member 222. At this time, the spring pushing member 231 is aligned with the buckle on the assembly turntable 6, which facilitates pushing the spring into the buckle.

[0060] In this invention, the spring pushing mechanism 23 further includes a spring pushing rod 232 that is slidably disposed on the spring feeding rack 223 in the transverse direction. One end of the spring pushing rod 232 is fixedly connected to the spring pushing member 231. An L-shaped spring pushing connector 233 is rotatably mounted on the spring feeding rack 223. One end of the spring pushing connector 233 is rotatably connected to one end of the spring pushing rod 232. The other end of the spring pushing connector 233 is rotatably connected to the spring pushing transmission assembly 25 through a vertically disposed spring pushing pull rod assembly 234.

[0061] Along the movement path of the spring, a spring distribution mechanism 26 is also provided between the spring vibrating plate 21 and the spring reversing mechanism 22; the spring distribution mechanism 26 is used to separate multiple springs removed from the spring vibrating plate 21 in sequence and allow each spring to enter the spring through hole 2221 individually.

[0062] The spring-loaded material distribution mechanism 26 includes a material distribution cylinder mounting base 261, a spring-loaded material distribution cylinder 262, a spring-loaded material distribution connecting base 263, a material distribution slider slide rail assembly 264, an upper material distribution block 265, and a lower material distribution block 266. The material distribution cylinder mounting base 261 is fixedly connected to the spring vibrating plate 21. The spring-loaded material distribution cylinder 262 is fixedly mounted on the material distribution cylinder mounting base 261, and its drive end is fixedly connected to the spring-loaded connecting base 263 located below the material distribution cylinder mounting base 261. The slider of the material distribution slider slide rail assembly 264 is fixedly connected to the material distribution cylinder mounting base 261. The slide rail of component 264 is fixedly connected to the spring distributing connecting seat 263, and the spring distributing cylinder 262 drives the spring distributing connecting seat 263 to reciprocate; the upper distributing block 265 is fixedly connected to the distributing cylinder mounting seat 261, and the upper distributing block 265 is provided with an upper distributing channel 2651, which is connected to the discharge end of the spring vibrating plate 21 through the upper spring guide tube 2652; the lower distributing block 266 is fixedly connected to the spring distributing connecting seat 263, and the lower distributing block 266 is provided with a lower distributing channel 2661, which is connected to the spring receiving through hole 2211 through the lower spring guide tube 2662.

[0063] A material distribution block 267 is provided on the upper material distribution block 265. The material distribution block 267 is used to block the upper material distribution channel 2651, limiting only one spring in the upper material distribution channel 2651 to the lower material distribution channel 2661. A return spring is provided between the material distribution block 267 and the upper material distribution block 265. A material distribution pin 2671 adapted to the material distribution block 267 is installed on the spring material distribution connecting seat 263. The material distribution pin 2671 is used to push the material distribution block 267 to move closer to the upper material distribution block 265. The material distribution pin 2671 corresponds to the position of the return spring and is located on both sides of the material distribution block 267.

[0064] The spring enters the upper distribution channel 2651 through the upper spring guide tube 2652. The spring distribution cylinder 262 pushes the spring distribution connecting seat 263 to move outward, causing the lower distribution block 266 and the distribution stop pin 2671 to move together. During this process, the spring distribution connecting seat 263 drives the lower distribution channel 2661 to align with the upper distribution channel 2651, causing the spring in the upper distribution channel 2651 to fall into the lower distribution channel 2661. At the same time, the distribution stop pin 2671 abuts against and drives the distribution stop block 267 to block the upper distribution channel 2651, preventing the next spring from falling. In this way, each time the lower distribution channel 2661 aligns with the upper distribution channel 2651, it can be ensured that there is only one spring in the upper distribution channel 2651 and only the bottom spring falls into the lower distribution channel 2661, ensuring the normal feeding of springs. After one spring feeding cycle, the spring distribution cylinder 262 drives the spring distribution connecting seat 263 to move in the opposite direction, causing the lower distribution channel 2661 to intersect with the upper distribution channel 2651. Simultaneously, the reset spring pushes the distribution stop block 267 to reset, stopping its obstruction of the upper distribution channel 2651, allowing subsequent springs to fall in preparation for feeding. To facilitate the timely and rapid delivery of springs from the lower spring guide tube 2662 to the spring through hole 2221, the lower distribution channel 2661 is provided with an air inlet hole 2663, which is connected to an external air supply source. The air supply source blows the springs from the lower spring guide tube 2662 to the spring through hole 2221.

[0065] like Figure 1 , Figure 2 , Figures 9 to 16 As shown in the figure, in this invention, the shovel punching and feeding device 3 includes a shovel material conveying station 31, a shovel forming station 32, a shovel clamping station 33, a shovel forming transmission mechanism 34, and a shovel clamping transmission mechanism 35; wherein, the shovel material conveying station 31 includes a shovel material tray 3111, which is vertically arranged and rotates around its own axis, and a shovel material strip 7 is wound on the shovel material tray 3111; the shovel forming station 32 is arranged downstream of the shovel material tray 3111 along the moving direction of the shovel material strip 7, and the shovel forming station 32 is used to punch the shovel material strip 7 moving along the X direction to form The paddle 92 is formed and pushed out; the paddle clamping station 33 is set along the Y direction outside the paddle forming station 32. The paddle clamping station 33 is used to clamp and fix the paddle 92 and drive it to move towards or away from the assembly turntable 6; the paddle forming transmission mechanism 34 drives the paddle forming station 32 to the external power device 8 and transmits power to the paddle forming station 32; the paddle clamping transmission mechanism 35 drives the paddle clamping station 33 to the external power device 8 and transmits power to the paddle clamping station 33.

[0066] In this invention, the paddle strip 7 is wound around the paddle tray 3111. The paddle strip 7 is a long strip structure. It is moved from the paddle tray 3111 to the paddle forming station 32 for punching and forming into a paddle 92. After forming, the paddle 92 is removed by the paddle forming station 32 and then clamped and fixed by the paddle clamping station 33. Then it moves to the assembly turntable 6. During the movement, it gradually approaches the buckle body 91 set on the assembly turntable 6 and assembles the paddle 92 into the buckle body 91, completing the paddle 92 punching and feeding action.

[0067] The paddle conveyor station 31 includes a paddle feeding mechanism 311 and a paddle unloading mechanism 312 located downstream of the paddle forming station 32 along the moving direction of the paddle 7. The paddle feeding mechanism 311 includes a paddle tray 3111 and a paddle reversing wheel 3112. The paddle reversing wheel 3112 is located between the paddle tray 3111 and the paddle forming station 32 along the moving direction of the paddle 7. The paddle reversing wheel 3112 is used to reverse the direction of the paddle 7 so that the paddle 7 can enter the paddle forming station 32 in the X direction.

[0068] The remaining strip material 7 after punching at the forming station 32 is received and ejected by the strip ejection mechanism 312. The strip ejection mechanism 312 includes an ejection mounting base 3121, an ejection clamping wheel assembly 3122, a ratchet and pawl assembly 3123, and a strip ejection cylinder 3124. The ejection mounting base 3121 is vertically fixed above the forming station 32. The ejection clamping wheel assembly 3122 is rotatably mounted on the ejection mounting base 3121 and includes a driving clamping wheel 31221 and a driven clamping wheel 31222 arranged close to each other. 222, the axes of the active clamping wheel 31221 and the driven clamping wheel 31222 are parallel to the Y direction. The active clamping wheel 31221 and the driven clamping wheel 31222 cooperate with each other to clamp and feed the remaining strip 7 after punching to move downward. The ratchet and pawl assembly 3123 includes a ratchet 31231 fixed to one side of the active clamping wheel 31221 and a pawl 31232 adapted to the ratchet 31231 and rotatably mounted on the unloading mounting seat 3121. The strip unloading cylinder 3124 is arranged vertically, and the pawl 31232 is controlled by the strip unloading cylinder 3124. The drive end of the strip ejection cylinder 3124 pushes the pawl 31232 to rotate, which in turn drives the active clamping wheel 31221 to rotate together. The active clamping wheel 31221 and the driven clamping wheel 31222 are matched, which drives the strip 7 clamped between the two to move downward, thus completing the ejection action.

[0069] The paddle forming station 32 includes a paddle forming base 321, on which a paddle punching mechanism 322 and a paddle pushing mechanism 323 arranged along the Y direction outside the paddle punching mechanism 322 are mounted. The paddle punching mechanism 322 is used to punch the paddle material strip 7 into paddles 92. The paddle punching mechanism 322 includes a punching mounting base 3221, a punching forming block 3222, and a punch 3223. The punching mounting base 3221 is mounted on the paddle forming base 321. A strip channel 32211 is provided on the 3221, which is arranged in the X direction. A blanking forming block 3222 is installed in the blanking mounting base 3221 and is positioned above the strip channel 32211. A vertically penetrating pusher forming hole 32221 is provided on the blanking forming block 3222, and a pusher pushing groove 32222 is recessed along the Y direction on the blanking forming block 3222. The strip channel 32211 intersects with the pusher forming hole 32221, and the pusher forming hole 32221 intersects with the pusher pushing groove 32222. The pusher groove 32222 intersects with the sheet pusher groove 32222; the punch 3223 is vertically slidably disposed in the sheet forming hole 32221, and the punch 3223 cooperates with the blanking forming block 3222 to blank the sheet material strip 7 to form the sheet 92 and move the sheet 92 upward into the pusher groove 32222; after the sheet material strip 7 enters the blanking mounting base 3221 through the material strip channel 32211, it is located below the blanking forming block 3222; the punch 3223, which is vertically slidably disposed in the sheet forming hole 32221, and the punch 3223 intersects with the pusher groove 322222; the punch 3223 is vertically slidably disposed in the sheet forming hole 32221, and the punch 3223 is vertically slidably disposed in the pusher groove 3222222; the punch 3223 is vertically slidably disposed in the pusher groove 32 ... The forming block 3222 cooperates with the die-cutting strip 7 to form the die 92 and moves the die 92 upward into the die pushing groove 32222. After the die 7 moves to the position of the punch 3223, the punch 3223 moves upward to abut against the die 7. The punch 3223 cooperates with the forming block 3222 to form the die 92. After the punch 3223 continues to drive the die 92 upward until it is moved into the die pushing groove 32222, waiting to be pushed out.

[0070] The paddle pushing mechanism 323 is used to push the formed paddle 92 out; the paddle pushing mechanism 323 includes a paddle push rod 3231 that is slidably disposed on the outside of the punching mounting base 3221 along the Y direction. One end of the paddle push rod 3231 is located in the paddle pushing groove 32222. A push rod reset spring (not shown in the figure) is provided between the paddle push rod 3231 and the paddle forming base 321. The push rod reset spring is used to pull the paddle push rod 3231 to move and reset along the X direction to the side away from the paddle punching mechanism 322. The paddle push rod 3231 slides back and forth along the Y direction and is located in the paddle push groove 32222. When the paddle push rod 3231 moves towards the side closer to the punch 3223, it pushes the paddle 92 and continuously pushes it out. When the paddle push rod 3231 moves away from the punch 3223, it leaves a space for the paddle forming hole 32221, so that the punch 3223 can continue to drive the paddle 92 to move up through the paddle forming hole 32221 into the paddle push groove 32222, thus satisfying the action of the paddle push rod 3231 continuously pushing the paddle 92.

[0071] The die-cutting mechanism 322 also includes a die-cutting chamfering assembly 3224 for chamfering the die 92, facilitating loading, assembly, and use. The die-cutting chamfering assembly 3224 is positioned along the Y-direction on the side away from the die-pushing mechanism 323. The die-cutting chamfering assembly 3224 includes an upper chamfering die 32241 and a lower chamfering die 32242. The upper chamfering die 32241 is vertically slidably mounted on the die-cutting mounting base 3221 and is located above the die-pushing groove 32222. An upper chamfering return spring is provided between the upper chamfering die 32241 and the die-cutting mounting base 3221 to push the upper chamfering die. 32241 moves upward and resets; the lower chamfering mold 32242 is adapted to the upper chamfering mold 32241, and the lower chamfering mold 32242 is vertically slidably set below the upper chamfering mold 32241; both the upper chamfering mold 32241 and the lower chamfering mold 32242 can slide up and down, and the pushed-out paddle 92 falls on the lower chamfering mold 32242, cooperates with the upper chamfering mold 32241, and chamfers it; the punching mounting base 3221 is provided with a clearance groove 32212 for avoiding the clamping end of the paddle clamping station 33, and the abutting ends of the upper chamfering mold 32241 and the lower chamfering mold 32242 are located in the clearance groove 32212;

[0072] The paddle forming base 321 is also equipped with a strip feeding mechanism 324 arranged along the X direction outside the paddle punching mechanism 322. The strip feeding mechanism 324 is used to feed the paddle strip 7 into the paddle punching mechanism 322. The strip feeding mechanism 324 includes a lower clamping block 3241 and an upper clamping block 3242. The lower clamping block 3241 is slidably arranged on the paddle forming base 321. The lower clamping block 3241 is recessed with a strip feeding groove 32411 arranged along the X direction. The strip feeding groove 32411 and the strip channel 32211 are on the same plane. The upper clamping block 3242 is used in conjunction with the lower clamping block 3241. The upper clamping block 3242 is protruded with a clamping protrusion 32421 that matches the strip feeding groove 32411.

[0073] Several limiting pins (obscured in the figure) are fixed on the upper clamping block 3242. These limiting pins are inserted into the lower clamping block 3241. The limiting pins restrict the upper clamping block 3242 to move vertically only, and prevent it from moving horizontally in the X direction. At the same time, the material feeding groove 32411 and the feeding protrusion 32421 are matched, which also restricts the upper clamping block 3242 from moving horizontally in the Y direction. This results in the material feeding groove 32411 and the feeding protrusion 32421 only being able to move the feed strip 7. When clamping and releasing the material strip 7, the lower clamping block 3241, which is slidably set on the material strip forming seat 321, drives the material strip 7 to move together along the X direction toward the material strip punching mechanism 322. When releasing the material strip 7, a clamping block reset spring is provided between the lower clamping block 3241 and the material strip forming seat 321. The clamping block reset spring can pull the lower clamping block 3241 and the upper clamping block 3242 in the opposite direction along the X direction. At the same time, it will not interfere with the material strip 7, ensuring that the material strip 7 can continue to be clamped and fed next time.

[0074] The paddle clamping station 33 includes a clamping mounting base 331, on which a paddle clamping mechanism 332 is mounted, which can rotate towards or away from the assembly turntable 6. The paddle clamping mechanism 332 includes a jaw mounting base 3321, a jaw assembly 3323, a jaw push rod 3324, and a paddle wheel 3326. The jaw mounting base 3321 is rotatably mounted on the clamping mounting base 331, and the bottom of the jaw mounting base 3321 is fixedly connected to a vertically arranged clamping bushing 3322, which can rotate around its own axis. The jaw assembly 3323 is mounted on the jaw mounting base 3321, and the jaws... The component 3323 is located near the paddle forming station 32. The gripper assembly 3323 includes a vertically arranged upper gripper 33231 and a lower gripper 33232. The gripper push rod 3324 is controlled by the push cylinder 3325. The gripper push rod 3324 is located between the upper gripper 33231 and the lower gripper 33232. The gripper push rod 3324 is used to push the ends of the upper gripper 33231 and the lower gripper 33232 closer to each other. The dial wheel 3326 is slidably sleeved on the outside of the gripper assembly 3323. The dial wheel 3326 is used to push the ends of the upper gripper 33231 and the lower gripper 33232 away from each other.

[0075] During the rotation of the clamping bushing 3322 around its own axis, the clamping bushing 3322 can drive the gripper mounting base 3321 to rotate together. The gripper mounting base 3321 is equipped with a gripper assembly 3323, which can drive the gripper assembly 3323 and the gripped paddle 92 to rotate together around the axis of the clamping bushing 3322, thereby driving the paddle 92 to move closer to or further away from the assembly turntable 6.

[0076] It should be noted that in the lever clamping mechanism 332, the closure of the upper jaw 33231 and the lower jaw 33232 is achieved by driving the drive end of the cylinder 3325 to move the jaw push rod 3324 towards the side closer to the lever punching mechanism 322. Since both the upper jaw 33231 and the lower jaw 33232 are hinged, when the jaw push rod 3324 moves towards the side closer to the lever punching mechanism 322, it can push the rear ends of the upper jaw 33231 and the lower jaw 33232, causing their front ends to approach each other, completing the closing action and facilitating the clamping of the lever 9. 2. Clamping; When the upper jaw 33231 and lower jaw 33232 need to be opened, the dial wheel 3326 moves to the side closer to the cutting mechanism 322. The rear ends of the upper jaw 33231 and lower jaw 33232 are provided with inclined surfaces. The dial wheel 3326 simultaneously abuts against the two inclined surfaces and moves continuously, so that the dial wheel 3326 continuously presses the rear ends of the upper jaw 33231 and lower jaw 33232, causing the front ends of the upper jaw 33231 and lower jaw 33232 to move away from each other, completing the opening action, thereby releasing the cutting mechanism 92.

[0077] Preferably, the paddle forming transmission mechanism 34 includes a punch transmission assembly 341, a paddle push rod transmission assembly 342, a strip clamping transmission assembly 343, and a paddle chamfering transmission assembly 344; wherein, the punch transmission assembly 341 is used to drive the punch 3223 to reciprocate vertically; the paddle push rod transmission assembly 342 is used to drive the paddle push rod 3231 to reciprocate along the Y direction; the strip clamping transmission assembly 343 is used to drive the upper clamping block 3242 to press down the lower clamping block 3241, and push the lower clamping block 3241 and the upper clamping block 3242 together to move along the X direction toward the side closer to the paddle punching mechanism 322; the paddle chamfering transmission assembly 344 is used to drive the upper chamfering die 32241 to move vertically downward and drive the lower chamfering die 32242 to move vertically upward.

[0078] The material conveying transmission assembly 343 includes an upper clamping block pressing roller rotatably disposed above the upper clamping block 3242 and a lower clamping block pushing roller rotatably mounted on the outside of the lower clamping block 3241 along the X direction. When the upper clamping block 3242 and the lower clamping block 3241 cooperate to clamp the paddle material belt 7, the upper clamping block pressing roller moves down to press the upper clamping block 3242. When the upper clamping block 3242 and the lower clamping block 3241 cooperate to transfer the paddle material belt 7, the lower clamping block pushing roller pushes the lower clamping block 3241, thereby driving the upper clamping block 3242 and the paddle material belt 7 to complete the transfer together.

[0079] The paddle clamping transmission mechanism 35 includes a clamping bushing transmission assembly 351 and a paddle wheel transmission assembly 352. The clamping bushing transmission assembly 351 is used to drive the clamping bushing 3322 to reciprocate around its own axis. The paddle wheel transmission assembly 352 is used to drive the paddle wheel 3326 to reciprocate along the extension direction of the gripper assembly 3323.

[0080] like Figure 2 , Figure 17 , Figure 18As shown, the good product inspection device 4 includes a good product inspection mounting block 41, a defective product reset component 43, a good product inspection actuator 44, and a good product inspection sensor 46. One end of the good product inspection mounting block 41 is rotatably mounted on the clamping mounting base 331 via a first good product inspection connecting shaft 42. A first inspection reset torsion spring (not shown) is installed between the good product inspection mounting block 41 and the clamping mounting base 331. The good product inspection mounting block 41 is positioned towards the side closest to the assembly turntable 6. The defective product reset component 43 is fixedly mounted on the good product inspection mounting block 41. 43 is adapted to the dial 3326. The defective product reset component 43 drives the good product detection mounting block 41 to rotate towards the side closer to the dial clamping mechanism 332. The good product detection actuator 44 is rotatably mounted on the other end of the good product detection mounting block 41 via the second good product detection connecting shaft 45. A second detection reset torsion spring (not shown in the figure) is installed between the good product detection actuator 44 and the good product detection mounting block 41. The good product detection actuator 44 has an arc-shaped actuation groove 441 adapted to the dial 92. The good product detection sensor 46 is adapted to the good product detection actuator 44. Under normal conditions, the good product detection actuator 44 abuts against the good product detection sensor 46.

[0081] The spring buckle unloading device 5 includes a vertically arranged spring buckle unloading cylinder 51. A good product unloading pipe 52 and a defective product unloading pipe 53, arranged vertically from top to bottom, are mounted on the drive end of the spring buckle unloading cylinder 51; alternatively, a defective product unloading pipe 53 and a good product unloading pipe 52, arranged vertically from top to bottom, are mounted on the drive end of the spring buckle unloading cylinder 51. The spring buckle unloading cylinder 51 is controlled by a good product detection sensor 46.

[0082] The assembly turntable 6 includes a turntable body 61 and a station opening and closing mechanism 62. The turntable body 61 is rotatably arranged and has at least four assembly stations 611 equidistantly arranged along its circumference. The assembly stations 611 are used to fix or release the fasteners 91. The station opening and closing mechanism 62 is driven and connected to an external power device 8. The station opening and closing mechanism 62 is used to control one of the assembly stations 611 to open and receive the fasteners 91, and simultaneously control another assembly station 611 to open and release the fasteners 91.

[0083] The working principle is briefly explained below based on the above structural description:

[0084] First, the fastener 91 is loaded: the fasteners 91, which are sequentially moved out by the fastener vibrating plate 11, slide freely downward along the fastener lower guide rail 121. During the descent, the fastener distribution plate 134 divides the fasteners 91, and one fastener 91 after division slides freely onto the fastener loading carrier plate 1312. The fastener translation pusher 1321 pushes the fastener translation pusher plate 1322 to move along the X direction. The fastener translation pusher plate 1322 pushes the fastener 91 to the side closer to the assembly turntable 6, so that it is pushed onto an assembly station 611 of the assembly turntable 6, thus completing the fastener 91 loading process.

[0085] The buckle body 91, pushed onto the assembly station 611, is moved towards the spring feeding device 2 by the turntable body 61 for spring assembly. Specifically, the springs removed from the spring vibrating plate 21 are divided by the spring distribution mechanism 26 and then enter the spring through-hole 2221 through the spring receiving through-hole 2211. The spring reversing component 222 drives the spring to reverse, so that the end of the spring faces the side closer to the assembly turntable 6. At this time, the spring through-hole 2221 is aligned with the spring pushing component 231. The spring pushing component 231 passes through the spring pushing through-hole 2212 and pushes the spring located in the spring through-hole 2221 towards the side closer to the assembly turntable 6. The springs are pushed into the interior of the buckle body 91 through the slotted through-hole, completing the spring feeding action of the buckle body 91.

[0086] After the spring is assembled into the buckle body 91, the buckle body 91 and the spring are moved together to the fork-mounting device 3 by the turntable body 61 for the fork assembly process, as follows:

[0087] When the paddle 92 is formed, the paddle strip 7 is clamped and fed into the strip channel 32211, and enters the punching mounting seat 3221 through the strip channel 32211. The punch transmission assembly 341 drives the punch 3223 to move upward. The punch 3223 cooperates with the punching forming block 3222 to punch the paddle strip 7 and form the paddle 92. Then the punch 3223 continues to move upward, driving the paddle 92 to move upward into the paddle pushing groove 32222, waiting to be pushed out.

[0088] When the paddle 92 is removed, the paddle push rod transmission assembly 342 drives the paddle push rod 3231 to slide back and forth along the Y direction. When the paddle push rod 3231 moves towards the side closer to the punch 3223, the paddle push rod 3231 pushes the paddle 92 to move it out. When the paddle push rod 3231 moves away from the punch 3223, it leaves a space for the paddle forming hole 32221, so that the punch 3223 can continue to drive the next paddle 92 to move up into the paddle pushing groove 32222.

[0089] When the paddle 92 is fed, the drive end of the push cylinder 3325 drives the gripper push rod 3324 to move closer to the paddle punching mechanism 322, pushing the rear ends of the upper gripper 33231 and the lower gripper 33232 so that their front ends come closer to each other and cooperate to clamp and fix the paddle 92; the clamping bushing transmission assembly 351 drives the clamping bushing 3322 to rotate around its own axis, thereby driving the gripper assembly 3323 and the clamped paddle 92 to rotate together around the axis of the clamping bushing 3322. The movement causes the lever 92 to move closer to the assembly turntable 6. During the movement of the lever 92, the assembly station 611 also causes the buckle body 91 to rotate together. The buckle body 91 and the lever 92 move closer to each other until the lever 92 is inserted into the buckle body 91. During this process, the lever 92 abuts against the inside of the buckle body 91. The two legs of the lever 92 are squeezed and extend to both sides along the inner wall of the buckle body 91, so that one leg abuts against the spring and the other leg extends out of the opening of the buckle body 91 and abuts against the buckle body 91.

[0090] Then, the dial 3326 moves to the side closer to the die-cutting mechanism 322. The dial 3326 drives the front ends of the upper jaw 33231 and the lower jaw 33232 to move away from each other, completing the opening action and releasing the die 92. Then, the clamping bushing transmission assembly 351 drives the clamping bushing 3322 to rotate in the opposite direction, driving the jaw assembly 3323 to move away from the assembly turntable 6 until it returns to the clearance groove 32212 to clamp and fix the next die 92.

[0091] After the buckle body 91 on the assembly station 611 passes through the assembly lever 92, it forms a spring buckle. A spring buckle that can be opened or closed normally by compressing the spring is defined as a good product; conversely, a spring buckle that cannot be opened or closed normally is a defective product. The spring buckle on the assembly station 611 continues to move toward the good product detection device 4. During the movement, the actuating end of the lever 92 extending out of the buckle body 91 abuts against the arc-shaped actuating groove 441. The good product detection actuator 44 pushes the lever 92 to compress the spring. At the same time, the good product detection actuator 44 separates from the good product detection sensor 46. After the spring buckle continues to be driven, the lever 92, under the elastic action of the spring, pushes the good product detection actuator 44 to move in the opposite direction and abut against the good product detection sensor 46. At this time, the current spring buckle is defined as a good product. If the spring buckle continues to be driven and the lever 92 is not subjected to the elastic force of the spring, or if the elastic force of the spring does not push the good product detection actuator 44 to move in the opposite direction and abut against the good product detection sensor 46 through the lever 92, then the good product detection actuator 44 will remain separated from the good product detection sensor 46. At this time, the spring buckle unloading cylinder 51 moves up or down, causing the defective product unloading pipe 53 to correspond with the assembly station 611. The station opening and closing mechanism 62 controls the assembly station 611 to open and release the buckle body 91 into the defective product unloading pipe 53. Conversely, it controls the assembly station 611 to open and release the buckle body 91 into the good product unloading pipe 52 for unloading.

[0092] When the good product detection actuator 44 is separated from the good product detection sensor 46, the defective product reset component 43 is driven by the good product detection actuator 44 to move in the opposite direction and approach the dial wheel 3326. The clamping sleeve 3322 drives the dial wheel 3326 to move towards the side closer to the assembly turntable 6. At this time, the defective product reset component 43 is moved by the dial wheel 3326, causing the good product detection actuator 44 to rotate towards the side closer to the dial wheel 3326 until it comes into contact with the good product detection sensor 46. When the good product detection actuator 44 and the good product detection sensor 46 are in contact, the defective product reset component 43 is moved by the good product detection actuator 44 to the side of the dial wheel 3326. Since there is a gap between the defective product reset component 43 and the dial wheel 3326, the dial wheel 3326 cannot move the defective product reset component 43, and therefore does not need to drive the good product detection actuator 44 to rotate.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
