Description

Technical Field

[0001] This utility model relates to the field of fish mouth buckle assembly technology, and in particular to a fish mouth buckle assembly machine. Background Technology

[0002] The fish-mouth buckle is a type of hardware accessory commonly used in decorations, jewelry, and pendants. Its structure can be divided into three parts: the main body, the door seal, and the buckle ring. After the door seal and torsion spring are formed, they are inserted into the main body, and the buckle ring is inserted into the buckle position at the bottom of the main body to complete the assembly of the fish-mouth buckle.

[0003] In related technologies, specialized assembly equipment is typically used to assemble the three parts of the fish-mouth buckle to improve assembly efficiency. The main body needs to be positioned and fixed on the assembly station of the equipment before the door seal, serving as the starting point for the fish-mouth buckle assembly process. However, because the door seal contains a torsion spring, which is prone to falling out of the door seal due to external factors, unstable door seal material supply can lead to problems with the smooth connection of the assembly process, affecting the fish-mouth buckle assembly efficiency.

[0061] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0062] In embodiments of this utility model, such as Figure 1 As shown, the fish-mouth buckle assembly machine includes a base 1, a door seal feeding device 2, a torsion spring forming device 3, a main body feeding device 4, a door seal pushing device 5, a buckle assembly device 6, and a fish-mouth buckle picking device 7. The base 1 is provided with a rotating turntable 11 and a fixed workstation 12. The turntable 11 rotates in a preset direction, and the workstation 12 is located above the turntable 11. The turntable 11 is arranged with multiple card holder assemblies 13.

[0063] The door seal feeding device 2, the torsion spring forming device 3, the main body feeding device 4, the door seal pushing device 5, the buckle assembly device 6, and the fish mouth buckle picking device 7 surround the turntable 11, with the door seal feeding device 2 located at the front end of the torsion spring forming device 3 and the main body feeding device 4 located at the rear end of the torsion spring forming device 3.

[0064] In this embodiment, the turntable 11 can drive the card seat assembly 13 to pass sequentially through the door seal feeding device 2, the torsion spring forming device 3, the main body feeding device 4, the door seal pushing device 5, the buckle assembly device 6, and the fish mouth buckle picking device 7. The door seal feeding device 2 feeds the door seal 82 to the card seat assembly 13, the torsion spring forming device 3 forms a torsion spring on the door seal 82 of the card seat assembly 13, the main body feeding device 4 feeds the main body 81 to the card seat assembly 13, the door seal pushing device 5 assembles the door seal 82 into the main body 81, the buckle assembly device 6 assembles the buckle 83 into the main body 81, and finally the fish mouth buckle picking device 7 removes the assembled fish mouth buckle from the card seat assembly 13, thereby completing the overall assembly process of the fish mouth buckle.

[0065] Since the door seal feeding device 2 is located at the front end of the torsion spring forming device 3 and the main body feeding device 4 is located at the rear end of the torsion spring forming device 3, the door seal 82 is fixed to the card seat assembly 13 before the main body 81. The torsion spring is formed on the door seal 82 by the torsion spring forming device 3, which ensures the assembly stability of the torsion spring and the door seal 82. This can effectively prevent the torsion spring from falling out of the door seal 82 during the transfer process. At the same time, the door seal 82 is fixed and then the main body 81 is fixed, which can simultaneously ensure the stable feeding of the door seal 82 and the main body 81. This effectively avoids the problem of poor connection between the front and rear processes in the fish mouth buckle assembly process and ensures the assembly efficiency of the fish mouth buckle.

[0066] It should be noted that the base 1 is equipped with an indexing plate, the turntable 11 is connected to the rotating structure of the indexing plate, and the workstation plate 12 is connected to the base or locking structure of the indexing plate to ensure that the workstation plate 12 remains stationary while the turntable 11 rotates with the indexing plate.

[0067] Specifically, the workstation 12 has a door seal unloading station, a torsion spring forming station, and a main body unloading station. The door seal unloading station is located at the front end of the torsion spring forming station, and the main body unloading station is located at the rear end of the torsion spring forming station to ensure the assembly sequence between the door seal 82 and the main body 81, and to further ensure that the fish mouth buckle assembly machine can receive a stable supply of the door seal 82 and the main body 81. Among them, the door seal feeding device 2 has a door seal feeding section 201, which extends along a first predetermined direction to below the door seal unloading station. The door seal feeding section 201 is used to feed the door seal 82 to the card seat assembly 13. The main body feeding device 4 has a main body feeding section 401, which extends along a second predetermined direction to below the main body unloading station. The main body feeding section 401 is used to feed the main body 81 to the card seat assembly 13.

[0068] In addition, it should be noted that, in addition to forming the above-mentioned process stations, the workstation 12 can also form a door seal push-installation station, a buckle assembly station, and a fish mouth buckle material picking station, so as to connect with the device that completes the corresponding process, thereby facilitating the use of the turntable 11 to drive the card seat assembly 13 to rotate sequentially between each process, and to complete the sequential assembly of each part of the fish mouth buckle.

[0069] As an optional embodiment, the top surface of the workstation plate 12 may be formed with multiple mounting slots, each mounting slot can serve as one of the process stations for assembling the fish mouth buckle and be connected to the corresponding process device.

[0070] In order to fix the door seal 82 to the card holder assembly 13, such as Figure 2 and Figure 3As shown, the door seal feeding device 2 includes a door seal hopper 21, a first cylinder 22, a door seal transfer plate 23, and a door seal unloading guide rail 24. The door seal hopper 21 is mounted on the base 1 and has a door seal outlet. The fixed end of the first cylinder 22 is mounted on the base 1 via a first bracket 25, and the extended end of the first cylinder 22 extends in a first predetermined direction, which is the direction in which the first bracket 25 faces the door seal unloading station.

[0071] The door seal transfer plate 23 is slidably arranged on the first bracket 25, and the door seal transfer plate 23 is located on the extension path of the first cylinder 22; the door seal transfer plate 23 forms a door seal feeding groove 231, and when the first cylinder 22 extends, the door seal feeding groove 231 is located below the door seal unloading station. The door seal unloading guide rail 24 is installed on the base 1, and one end of the door seal unloading guide rail 24 is located at the door seal outlet. When the first cylinder 22 retracts, the door seal feeding groove 231 is flush with the other end of the door seal unloading guide rail 24.

[0072] The door seal 82 can be conveyed from the door seal hopper 21 to the door seal outlet, and then transferred from the door seal outlet and the door seal unloading guide rail 24 to the door seal feeding slot 231 of the door seal transfer plate 23. At this time, the first cylinder 22 pushes the door seal transfer plate 23 to move towards the door seal unloading station, and finally moves it above the card holder assembly 13. Thus, the first cylinder 22, the door seal transfer plate 23 and the door seal unloading guide rail 24 are used to complete the transfer and conveying of the door seal 82 between the door seal hopper 21 and the card holder assembly 13, and fix the door seal 82 in the card holder assembly 13.

[0073] Preferably, such as Figure 2 As shown, the door seal feeding guide 24 is inclinedly arranged on the base 1 so that the door seal 82 can be transferred between the door seal hopper 21 and the door seal feeding trough 231 by utilizing the weight of the multiple door seals 82. The door seal feeding guide 24 has a guide groove with the same width as the door seal 82 to ensure the accuracy of the conveying direction of the door seal 82.

[0074] It should also be noted that, to further ensure the stability of the door seal 82 within the card holder assembly 13, such as... Figure 3 As shown, the workstation plate 12 is connected to a pressing cylinder 124 via a bracket. The extended end of the pressing cylinder 124 is connected to a pressing block 125, and the pressing block 125 is located above the mounting groove of the door seal 82 in the card holder assembly 13. When the door seal transfer plate 23 pushes the door seal 82 to the card holder assembly 13, the pressing cylinder 124 can be used to push the pressing block 125 to extend, thereby embedding the door seal 82 into the mounting groove and ensuring the fixed stability of the door seal 82.

[0075] To facilitate the direct molding of the torsion spring on the door seal 82 of the card holder assembly 13, such as Figures 4 to 8As shown, the torsion spring forming device 3 includes a third support 31, a linear wire feeding assembly 32, a cutting and forming assembly 33, and a torsion spring mounting assembly 34. The third support 31 is connected to the base 1, and a wire reel 311 is connected to the third support 31. The linear wire feeding assembly 32 is disposed on the third support 31, and forms a wire inlet channel. One end of the wire inlet channel faces the wire reel 311, and the other end of the wire inlet channel faces the torsion spring forming station.

[0076] The cutting and forming assembly 33 is disposed on the third support 31. The cutting and forming assembly 33 has a torsion part 301 and a cutting part 302. The torsion part 301 extends obliquely relative to the extension direction of the wire inlet channel, and the cutting part 302 extends perpendicularly relative to the extension direction of the wire inlet channel. The torsion spring mounting assembly 34 is connected to the workstation plate 12 and is located above the torsion spring forming station. The torsion spring mounting assembly 34 has a pressing part 303, which extends along the workstation plate 12 toward the card holder assembly 13.

[0077] Understandably, after the door seal 82 is fixed to the card holder assembly 13, the turntable 11 drives the card holder assembly 13 to rotate at a certain angle to transfer the card holder assembly 13 to the torsion spring forming station. Subsequently, the linear feeding assembly 32 conveys the straightened metal wire to the area below the torsion spring forming station. At the same time, the torsion part 301 of the cutting and forming assembly 33 moves towards the wire inlet channel. The torsion part 301 torsionals the metal wire, and then, with the cooperation of the linear feeding assembly 32 and the torsion part 301, the metal wire is formed into a spirally coiled torsion spring structure. After the torsion spring is formed, the torsion part 301 and the cutting part 302 of the cutting and forming assembly 33 are used to cut the metal wire between the torsion spring and the linear feeding assembly 32, completing the linear forming action of the torsion spring on the door seal 82. This effectively reduces the secondary handling between the torsion spring and the door seal 82 and reduces the risk of the torsion spring falling off.

[0078] Specifically, such as Figure 6 As shown, the straight wire feeding assembly 32 includes a straightening roller group 321, a wire feeding wheel 322, and a wire outlet seat 323. The straightening roller group 321 may include multiple staggered rollers, and the wire inlet channel is formed between the staggered rollers so as to straighten the metal wire using the straightening roller group 321 and ensure the straightness of the metal wire when forming the torsion spring.

[0079] Two wire feeding rollers 322 are arranged between the straightening roller group 321 and the wire outlet seat 323. The straightened metal wire enters between the two wire feeding rollers 322 through the wire inlet channel. The wire outlet seat 323 has a wire outlet hole. After the metal wire is conveyed to the wire outlet seat 323 by the wire feeding rollers 322, it can be further straightened through the wire outlet hole and then conveyed to the torsion spring forming station, thereby further ensuring the straightness of the metal wire.

[0080] After the metal wire is fed to the torsion spring forming station, in order to twist the metal wire into a torsion spring shape, such as... Figure 3 , Figure 4 and Figure 7 As shown, the cutting and forming assembly 33 includes a torsion motor 331, a torsion baffle 332, a cutting motor 333, and a cutter 334. The torsion motor 331 and the cutting motor 333 are mounted on the third bracket 31. The torsion baffle 332 is connected to the extended end of the torsion motor 331, and the cutter 334 is connected to the extended end of the cutting motor 333. The torsion baffle 332 and the cutter 334 are located on both sides of the cable outlet 323, and a certain angle is formed between the torsion baffle 332 and the cable inlet channel.

[0081] During the torsion spring structure forming, the torsion motor 331 drives the torsion baffle 332 to extend at an angle and move it to the wire exit path of the wire exit seat 323. This allows the torsion baffle 332 to twist the front end of the metal wire at a certain angle, forcing the metal wire to twist and rotate around its own axis as it extends, thus forming a spirally coiled torsion spring structure. Subsequently, the torsion baffle 332 retracts, and the metal wire continues to extend to bring the torsion spring above the card holder assembly 13. Then, the torsion baffle 332 and the cutter 334 are driven to move simultaneously toward the metal wire, cutting the torsion spring from the metal wire groove, thereby completing the torsion spring forming action and fixing the torsion spring onto the door seal 82, completing the assembly of the torsion spring and the door seal 82.

[0082] To assemble the molded torsion spring onto the door seal 82 of the card holder assembly 13, as follows: Figure 8 As shown, the torsion spring mounting assembly 34 includes a connecting bracket 341, a pressing cylinder 342, and a pressing rod 343. The pressing cylinder 342 is connected to the workstation plate 12 via the connecting bracket 341, and is located above the card holder assembly 13. The pressing rod 343 is connected to the extended end of the pressing cylinder 342, and a hinge groove is formed on the door seal 82, with the pressing rod 343 located above the hinge groove. The pressing cylinder 342 is preferably a servo motor, and the torsion spring mounting shaft serves as a positioning structure for the door seal 82, fitting the hinge hole of the door seal 82 into the torsion spring mounting shaft. After the torsion spring is formed, the pressure cylinder 342 can be servo-rotated to drive the pressure rod 343 to rotate, limiting the torsion spring above the door seal 82 to limit the torsion spring and prevent it from flying out of the torsion spring forming station after cutting. At the same time, the pressure rod 343 continues to move to press the torsion spring into the hinge groove of the door seal 82, completing the assembly of the torsion spring and the door seal 82.

[0083] Furthermore, after the torsion spring is formed, since the end wall of the torsion spring extends into the helical section, to ensure that the end wall of the torsion spring can be pressed into the door seal 82, as follows: Figure 8As shown, the torsion spring mounting assembly 34 also includes a pressure plate 344, which is connected to the other end of the connecting bracket 341. The stop plate is located on the side of the pressure rod 343 away from the wire feeding component, and the stop plate is located above the inclined end wall of the torsion spring. This allows the stop plate to limit the inclined end wall of the torsion spring when it moves toward the door seal 82, and press the inclined end wall of the torsion spring into the door seal 82, thereby cooperating with the pressure rod 343 to complete the assembly action of the torsion spring and the door seal 82.

[0084] After the torsion spring is assembled into the door seal 82, in order to fix the main body 81 to the card holder assembly 13, as follows: Figure 9 and Figure 10 As shown, the main feeding device 4 includes a main material bucket 41, a second cylinder 42, a main transfer plate 43, and a main unloading guide rail 44. The main material bucket 41 is mounted on the base 1 and has a main material outlet. The fixed end of the second cylinder 42 is mounted on the base 1 via a second bracket 45, and the extended end of the second cylinder 42 extends in a second predetermined direction, which is the direction in which the second bracket 45 faces the main unloading station.

[0085] The main transfer plate 43 is slidably arranged on the second support 45, and the main transfer plate 43 is located on the extension path of the second cylinder 42. The main transfer plate 43 forms a main feeding groove 431. When the second cylinder 42 extends, the main feeding groove 431 is located below the main unloading station. The main unloading guide rail 44 is connected to the second support 45. The main unloading guide rail 44 forms a main transfer groove 441. When the second cylinder 42 retracts, the main feeding groove 431 is located below the main transfer groove 441, and the upper end of the main feeding groove 431 is connected to the main discharge port.

[0086] The main body 81 can be conveyed from the main body material bucket 41 to the main body discharge port, and then transferred from the main body discharge port and the main body unloading guide rail 44 to the main body feeding groove 431 of the main body transfer plate 43. At this time, the first cylinder 22 pushes the main body transfer plate 43 to move towards the main body unloading station, and finally moves to the top of the clamping assembly 13. Thus, the second cylinder 42, the main body transfer plate 43 and the main body unloading guide rail 44 are used to complete the transfer and conveying of the main body 81 between the main body material bucket 41 and the clamping assembly 13, and fix the main body 81 in the clamping assembly 13.

[0087] Preferably, such as Figure 9 As shown, the main body unloading guide rail 44 is vertically arranged on the base 1. The main body unloading guide rail 44 forms a main body transfer groove 441 that is adapted to the shape of the main body 81, so as to use the weight of the main body 81 to transfer the main body 81 from the main body material barrel 41 to the main body feeding groove 431, ensuring the accuracy of the conveying direction of the door seal 82.

[0088] It should also be noted that, to further ensure the stability of the door seal 82 within the card holder assembly 13, such as... Figure 10 As shown, a pressing cylinder 124 and a pressing block 125 are also arranged on the side of the main body unloading station facing the card seat assembly 13, so as to use the pressing block 125 to embed the main body 81 into the mounting groove of the main body 81 in the card seat assembly 13, thereby ensuring the connection stability between the main body 81 and the card seat assembly 13.

[0089] In addition, it should be noted that when the door seal 82 and the main body 81 are fixed to the card holder assembly 13, there may be a certain angle error between the door seal 82 and the main body 81 due to placement error or their own size error. If the door seal 82 and the main body 81 are assembled at this time, the door seal 82 may be misaligned, jammed or damaged, affecting the assembly efficiency and quality of the fish mouth buckle.

[0090] In this embodiment, as Figure 11 As shown, the card holder assembly 13 includes a first card holder 131 for mounting the main body 81 and a second card holder 132 for mounting the door seal 82. The first card holder 131 and the second card holder 132 are slidably connected. The door seal 82 has a locking position 821 facing the first card holder 131. When the second card holder 132 slides against the first card holder 131, the locking position 821 is engaged with the main body 81. Therefore, when assembling the door seal 82 and the main body 81, the second card holder 132 can be moved to abut against the first card holder 131 first, so that the locking position 821 is engaged with the main body 81 before the other structures of the door seal 82. Then, the door seal 82 is pushed to be fully engaged with the main body 81, so that the door seal 82 and the main body 81 are assembled in stages. If there is an angular error between the door seal 82 and the main body 81, the locking position 821 will not be able to lock into the main body 81, causing the assembly of the door seal 82 and the main body 81 to be suspended, effectively avoiding the problem of the door seal 82 getting stuck or damaged, ensuring the assembly efficiency of the fish mouth buckle, and reducing assembly damage.

[0091] Preferably, in order to facilitate the movement of the second card holder 132 toward the first card holder 131, the first card holder 131 is formed with a sliding groove and the second card holder 132 is formed with a sliding platform. The sliding groove and the sliding platform are slidably engaged to realize the sliding connection between the first card holder 131 and the second card holder 132 and to ensure the stability of the two when sliding relative to each other.

[0092] Specifically, to ensure the step-by-step assembly of the door seal 82 and the main body 81 can be completed, such as... Figure 12As shown, the door seal pushing device 5 includes a pusher assembly 51 and a door seal pushing assembly 52. ​​The pusher assembly 51 includes a third cylinder 511 and a pusher rocker arm 512. The third cylinder 511 is connected to the workstation plate 12 via a fourth bracket 513. The pusher rocker arm 512 is rotatably connected to the fourth bracket 513. The third cylinder 511 is used to push the pusher rocker arm 512 to rotate. The second clamping seat 132 is located on the lower end rotation path of the pusher rocker arm 512. The door seal pushing assembly 52 includes a fourth cylinder 521 and a pusher block 522. The fourth cylinder 521 is connected to the base 1 via a fifth bracket 525. The pusher block 522 is connected to the extended end of the fourth cylinder 521. The door seal 82 is located on the extension path of the pusher block 522.

[0093] Understandably, by utilizing the cooperation of the third cylinder 511 and the pusher lever 512, the second latch 132 can be moved, allowing it to abut against the first latch 131 and engage the latching position 821 of the door seal 82 into the main body 81. Furthermore, by utilizing the cooperation of the fourth cylinder 521 and the pusher block 522, the door seal 82 can be moved towards the main body 81 to assemble the door seal 82 with the main body 81. By controlling the sequence of the actions of the third cylinder 511 and the fourth cylinder 521, it can be ensured that after the second latch 132 abuts against the first latch 131 and the latching position 821 of the door seal 82 engages with the main body 81, the door seal 82 is moved towards the main body 81, completing the assembly of the door seal 82 with the main body 81. This achieves step-by-step assembly of the door seal 82 and the main body 81 and ensures the assembly sequence during distributed assembly of the door seal 82 and the main body 81.

[0094] Preferably, such as Figure 11 and Figure 12 As shown, a pusher arm 523 is formed at one end of the pusher block 522 facing the second card seat 132. The second card seat 132 is formed with a mounting slot 133 for mounting the door seal 82. The extension axis of the pusher arm 523 is located inside the mounting slot 133, and the width of the pusher arm 523 is smaller than the width of the mounting slot 133, so as to ensure that when the pusher block 522 extends, the pusher arm 523 can be inserted into the mounting slot 133 and push the door seal 82 to move towards the body, thus ensuring the relative stability of the movement between the pusher arm 523 and the door seal 82.

[0095] To further ensure that the extension axis of the push arm 523 is located in the mounting slot 133, such as Figure 12As shown, the door seal push-mount assembly 52 also includes an adjusting cylinder 524, which is mounted on the fifth bracket 525. The extended end of the adjusting cylinder 524 extends along the fifth bracket 525 toward the second mounting seat 132. The fixed end of the fourth cylinder 521 is mounted on the extended end of the adjusting cylinder 524. The extension of the adjusting cylinder 524 causes the fourth cylinder 521 and the pusher block 522 to move between the fifth bracket 525 and the second mounting seat 132, adjusting the relative position between the pusher block 522 and the mounting slot 133. This ensures that the pusher arm 523 of the pusher block 522 is adjusted to be flush with the mounting slot 133, thereby ensuring that the pusher block 522 can drive the pusher arm 523 out of the mounting slot 133, completing the assembly of the door seal 82.

[0096] In this embodiment, as Figure 13 and Figure 14 As shown, the buckle assembly device 6 includes a buckle material tank 61, a sixth bracket 62, and a buckle feeding guide rail 63. The buckle material tank 61 is installed on the base 1 and has a buckle outlet. The sixth bracket 62 is connected to the base 1 and is equipped with a fifth cylinder 64. The sixth bracket 62 is connected to a guide plate 65, and a push rod 66 is slidably connected to the guide plate 65. The extended end of the fifth cylinder 64 is connected to the push rod 66. The buckle feeding guide rail 63 is installed on the base 1, with one end located at the buckle outlet and the other end facing the top surface of the guide plate 65.

[0097] The buckle ring 83 can be conveyed from the buckle ring hopper 61 to the buckle ring outlet, and then transferred from the buckle ring outlet and buckle ring unloading guide rail 63 to the top surface of the guide plate 65. Subsequently, the fifth cylinder 64 pushes the push rod 66 to extend, so as to push the buckle ring 83 towards the card seat assembly 13 and fasten the buckle ring 83 to the tail end of the main body 81. Thus, the fifth cylinder 64, the guide plate 65 and the buckle ring unloading guide rail 63 complete the conveying of the buckle ring 83 and the assembly of the buckle ring 83 with the main body 81.

[0098] Preferably, the buckle ring feeding guide rail 63 is inclinedly arranged on the sixth bracket 62 so that the buckle ring 83 can complete the transfer action between the buckle ring 83 and the buckle ring material hopper 61 and the guide plate 65 by utilizing the weight of the buckle ring 83. The buckle ring feeding guide rail 63 is formed with a guide groove of the same diameter as the buckle ring 83 to ensure the accuracy of the conveying direction of the buckle ring 83.

[0099] It should also be noted that the door seal 82, the main body 81, and the buckle ring 83 can be transferred from the material barrel to the discharge port by vibration of the vibrating plate, so that they can be transported to the corresponding fixed process in the future.

[0100] Furthermore, it should be noted that a pin assembly device 53 is also provided between the door seal push-fit device 5 and the buckle push-fit device. For example... Figure 18As shown, the pin assembly device 53 includes a pin assembly bracket 531, a push cylinder 532, a pin clamp 533, a pin pushing cylinder 534, and a pin pressing cylinder 535. The pin assembly bracket 531 is mounted on the base. The fixed end of the push cylinder is located on the pin assembly bracket 531. The pin clamp 533 is connected to the extended end of the push cylinder 532. The extended end of the push cylinder extends towards the card holder assembly 13 to facilitate sending the pin clamp 533 above the card holder assembly 13. The pin pushing cylinder 534 is mounted on the base 1. The pin pressing cylinder 535 is connected to the workstation plate 12 via a bracket. When the turntable 11 rotates the card holder assembly 13 towards the pin assembly device 53, the pin pushing cylinder 534 is located below the card holder assembly 13, and the pin pressing cylinder 535 is located above the card holder assembly 13. A pin can be positioned at the extended end of the pin-pushing cylinder 534 so that the pin is pushed into the fish-mouth latch of the bracket assembly 13 by the pin-pushing cylinder 534, ensuring that the pin protrudes above the fish-mouth latch. Subsequently, the extended end of the pin-pressing cylinder 535 extends to rivet the pin into the fish-mouth latch, completing the assembly of the pin and the fish-mouth latch, and ensuring the connection stability between the door seal 82 and the main body 81.

[0101] In this embodiment, to remove the assembled fish-mouth buckle from the card holder assembly 13, as follows: Figure 15 and Figure 16 As shown, the fish-mouth buckle material handling device 7 includes a seventh bracket 71, a connecting plate 72, and a material handling component 73. The seventh bracket 71 is connected to the workstation plate 12 and is equipped with a sixth cylinder 74. The connecting plate 72 is slidably connected to the seventh bracket 71 and is connected to the extended end of the sixth cylinder 74. The material handling component 73 is connected to the seventh bracket 71 via a seventh cylinder 75, which is vertically arranged and used to move the material handling component 73 closer to or away from the card holder assembly 13. The material handling component 73 has a hook 76, which is located above the card holder assembly 13 and is connected to the sixth cylinder 74.

[0102] Then, the connecting plate 72 can be moved upward to the card holder assembly 13 by the sixth cylinder 74, which in turn moves the seventh cylinder 75 and the hook 76 to the top of the card holder assembly 13. Then, the seventh cylinder 75 drives the material take-up part 73 to extend, so that the hook 76 of the material take-up part 73 can hook the assembled fish mouth buckle. When the seventh cylinder 75 drives the material take-up part 73 to retract, the fish mouth buckle is taken out from the card holder assembly 13, thus completing the removal action of the fish mouth buckle.

[0103] Preferably, such as Figure 15 and Figure 16As shown, the material taking part 73 has three hooks 76. The first hook 76 is located on the outer wall of the hanging ring end of the fish mouth buckle, the second hook 76 is located on the inner wall of the hanging ring end of the fish mouth buckle, and the third hook 76 is located at the tail of the buckle ring 83. Thus, the first hook 76 and the third hook 76 can be used to clamp the overall structure of the fish mouth buckle. The first hook 76 and the second hook 76 can be used to clamp the hanging ring part of the fish mouth buckle, ensuring the stability of the fish mouth buckle when it is taken out of the card holder assembly 13.

[0104] It should also be noted that the base 1 is equipped with a fish mouth buckle storage bucket to store the fish mouth buckles taken out by the material taking part 73, so as to facilitate batch testing and use of the assembled fish mouth buckles.

[0105] In this embodiment, as Figure 17 As shown, a detection device 9 is provided between the door seal feeding device 2 and the torsion spring forming device 3, and a detection device 9 is provided between the torsion spring forming device 3 and the main body feeding device 4. The detection device 9 is connected to the workstation plate 12, and the detection end of the detection device 9 faces the card seat assembly 13, so as to use the detection device 9 to detect whether the corresponding assembly process has been completed.

[0106] Specifically, the detection device 9 includes a detection bracket 91 and a detection probe 92 connected to the detection bracket 91. The detection probe 92, located between the door seal feeding device 2 and the torsion spring forming device 3, faces the position of the door seal 82 in the card seat assembly 13 to detect whether the door seal 82 is fixed to the card seat assembly 13, ensuring that the door seal 82 feeding process is completed. The detection probe 92, located between the torsion spring forming device 3 and the main body feeding device 4, faces the position of the torsion spring in the card seat assembly 13 to detect whether the torsion spring is installed in the door seal 82, ensuring that the torsion spring forming and assembly process is completed.

[0107] Of course, a detection probe 92 is also arranged between the main feeding device 4 and the door seal pushing device 5. At this time, the detection probe 92 is facing the position of the main body 81 to detect the completion of the feeding process of the main body 81; a detection probe 92 is also arranged between the door seal pushing device 5 and the buckle assembly device 6. At this time, the detection probe 92 is facing the position of the door seal 82 to detect the completion of the door seal 82 pushing; a detection probe 92 is also arranged between the buckle assembly device 6 and the fish mouth buckle picking device 7. At this time, the detection probe 92 is facing the position of the buckle 83 to detect the completion of the buckle 83 buckling.

[0108] The above description is the preferred embodiment of this utility model.
