Description

Technical Field

[0001] The present invention relates to the technical field of hardware processing, and in particular to a lobster clasp accessory assembly device. Background Art

[0002] A lobster clasp is a type of jewelry, so named because of its shape, which resembles a curled-up lobster. While lobster clasps have enriched our lives, their production, manufacturing, and assembly require a complex process. They are assembled from three components. Current production capacity allows for mechanized mass production, but the small size, unique shape, and irregular shape of the components make the final assembly process impractical. Therefore, lobster clasps are ultimately assembled by hand.

[0003] Patent CN216601870U discloses a lobster clasp that can be quickly assembled. The chip is integrally formed, and the chip includes a front hook, a middle plate, a rear pressing portion and a rotating shaft. The middle plate is provided with a rotating shaft, and the rotating shaft extends from the left and right sides of the middle plate. The left and right ends of the rotating shaft are respectively inserted into the rotating shaft holes on the left and right sides. The torsion spring is mounted on the left end or the right end of the rotating shaft. The front hook extends from the front of the chip slot, and the rear pressing portion extends from the rear of the chip slot. The left and right side walls of the chip slot are provided with rotating shaft holes, and the rotating shaft extends from the left and right sides of the middle plate. The torsion spring can be mounted on the left end or the right end of the rotating shaft.

[0004] The above patent introduces the structure of the lobster clasp on the market. The lobster clasp includes a clasp body, a chip (also known as a K-piece) and a torsion spring. The installation of the chip and the torsion spring is especially inconvenient. The manual assembly seriously affects the overall benefits of the manufacturer. This backward production method that cannot be connected with modern industry has also seriously restricted the development of the industry. Secondly, manual assembly requires the outer end of the torsion spring to be squeezed and deformed after production so that it enters the groove of the chip. Manual operation will cause hand soreness. Based on this problem, a lobster clasp accessory assembly device has been developed. Summary of the Invention

The push rod 21 is provided on one side adjacent to the paddle 18. First, the chip is pushed into the processing groove 14 of the rotating part 10 by the paddle 18. The transmission mechanism drives the rotating part 10 to flip so that the chip is in a vertical processing state. At this time, the processing groove 14 corresponds to the push rod 21 and the pre-installation position 15. Then the push rod 21 pushes the chip in the processing groove 14 of the rotating part 10 to the pre-installation position 15. The pressing assembly 13 is actuated by the transmission mechanism to press the chip.

[0031] The rotating member 10 is semicircular, and the processing groove 14 is opened on the upper end surface of the rotating member 10.

The outer periphery of the rotating member 10 is provided with teeth and one side of the rotating member 10 is provided with a rack 24 that meshes with the rotating member 10 to form a linkage. The transmission mechanism forms a linkage with the rack 24 and drives the rack 24 to reciprocate in the vertical direction. In this embodiment, the transmission cylinder can use a cylinder or an actuator with a linear drive function to push the rack to move.

[0032] The chip torsion spring assembly mechanism 4 includes a movable plate 25 slidably connected to the frame 1, a mounting block 26, a first wheel 27, a first wheel drive motor 28, a pin component 29, a column 30, a cylinder 31 arranged on the column 30, a push rod 32 arranged at the end of the cylinder 31, a guide component 33 arranged at the bottom of the chip loading mechanism 2, a second wheel 34 and a second wheel drive motor 35, the guide component 33 is tilted at the bottom of the chip board 9 and the guide component 33 is linked to the transmission mechanism.

A second linkage member 37 is provided between the second wheel disc 34 and the movable plate 25. After the torsion spring of the torsion spring processing mechanism 3 is formed, the movable plate 25 approaches the torsion spring processing mechanism 3. At this time, the ejector pin component 29 removes the finished torsion spring and follows the movable plate 25 back to the chip board 9 position. Then the guide assembly 33 moves from bottom to top along the inclined direction to bend the outer end of the torsion spring and enter the groove of the chip.

In this embodiment, the wire rotating assembly 38 adopts a servo motor, and a cylinder is provided at the rear end of the servo motor. During the rotation of the steel wire by the servo motor, there is a backward action to make a torsion spring (the mechanism for making a torsion spring from steel wire is the existing technology and will not be described in detail). The wire rotating assembly 38 rotates the steel wire to form a torsion spring, and finally the steel wire is cut by the cutter assembly 40 to separate the finished torsion spring from the steel wire.

[0035] Working principle and usage process: First, the chip vibration track 6 transmits the chip, and the first pushing assembly 11 moves to make the chip enter the processing groove 14 of the rotating part 10. At this time, the chip is in a flat state, and then the rotating part 10 flips over to change the chip to a vertical processing state, that is, the groove for installing the torsion spring of the chip faces the torsion spring chip assembly mechanism 3, and the second pushing assembly 12 pushes the chip in the processing groove 14 to the pre-installed position 15 on the right side of the chip board 9, and the pressing assembly 13 presses down to clamp the chip board 9; at the same time, the steel wire on the wire turntable 7 is gradually transported to the torsion spring processing mechanism 3 for processing under the action of the turntable driving mechanism 8, and the traction plate 41 reciprocates in the horizontal direction to pull the steel wire, so that the steel wire on the wire turntable 7 reaches the steel wire rotating assembly 38 (using a servo motor in conjunction with a cylinder, that is, it has the function of rotating the steel wire and retracting it backward, thereby forming a multi-layer torsion spring structure), the steel wire is rotated by the motor to form a torsion spring, and then passed through The overcutter assembly 40 cuts the steel wire to separate the finished torsion spring from the steel wire, and finally the movable plate 25 approaches the torsion spring processing mechanism 3. At this time, the ejector component 29 removes the finished torsion spring and follows the movable plate 25 back to the chip plate 9 position. (The specific action is: the first wheel drive motor 28 drives the first wheel 27 to rotate, so that the first linkage 36 drives the sliding plate 25 to reciprocate in the front and rear directions; the second wheel drive motor 35 drives the second wheel 34 to rotate, and it is the second linkage 37 that drives the movable plate 25 to slide back and forth horizontally on the left and right sides), and then the guide assembly 33 moves from bottom to top along the inclined direction to bend the outer end of the torsion spring and enter the groove of the chip. Finally, the cylinder 31 drives the ejector rod 32 to completely push the outer end of the torsion spring into the groove or cut off the excess part. In this embodiment, the workstations that need to slide and press down can be driven by a cylinder or an actuator 31 with a linear drive function, or a linkage mechanism with a sequential action to make the overall action.
