Description

[0002] Lobster clasps are a type of hardware commonly used in decorations, jewelry, and pendants. In traditional processes, lobster clasps are assembled manually. Due to their small size and unique shape similar to lobsters, the assembly of lobster clasps is cumbersome and complicated. In the process of manual assembly, there are problems such as assembly difficulty, low assembly efficiency, and poor assembly effect.

[0003] In response to the defects of manually assembling lobster clasps, the company developed an assembly machine that can automatically assemble lobster clasps. Although it can solve the problems existing in manual assembly, the torsion spring is fed into the assembly machine by bending the steel wire through a bending mechanism to form a torsion spring, so that the torsion spring can be fixed on the fixed mold of the assembly machine for subsequent assembly processes. However, the bending of the torsion spring takes a long time, which affects the feeding efficiency of the torsion spring and thus affects the assembly efficiency of the lobster clasp.

[0030] Unless otherwise specified or defined, the term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0031] It should be noted that "fixed to" and "connected to" herein can be directly fixed or connected to an element, or indirectly fixed or connected to an element.

[0032] As Figures 1-5 As shown, a lobster buckle torsion spring feeding mechanism provided in this embodiment includes a vibration bowl 100, a material receiving part 200, a feeding assembly 300, a first bending assembly 400, and a second bending assembly 500. The vibration bowl 100, the material receiving part 200, the feeding assembly 300, and the first bending assembly 400 are installed on a lobster buckle assembling machine during use. The second bending assembly 500 is arranged at the bottom of the feeding assembly 300 and cooperates with the first bending assembly 400 to bend the extended parts at both ends of the torsion spring 600 so that it can be fixed on a fixed mold of the lobster buckle assembling machine in cooperation with a door seal.

[0033] The vibration bowl 100 adopts the vibration bowl 100 in the prior art as long as it can convey the torsion spring 600 to the material receiving part 200.

[0034] The material receiving part 200 is inclined downward from top to bottom from the feeding port end to the discharging port end. The feeding port of the material receiving part 200 is connected to the discharging port of the vibration bowl 100. And a third base 210 is arranged at the bottom of the material receiving part 200, and it is fixed on the lobster buckle assembling machine by connecting with the lobster buckle assembling machine through the third base 210.

[0035] It is understandable that a sensor for detecting the arrival of the torsion spring 600 is provided at the discharge port of the material receiving part 200, and it is cooperated with the vibrating disk 100 to control the stop of the conveyance of the torsion spring 600 when the torsion spring 600 exists at the position of the discharge port of the material receiving part 200, so as to prevent the torsion spring 600 from jamming the material receiving part 200 or even falling off. Such a structure can be realized by using the existing technology and will not be elaborated here.

[0036] The feeding assembly 300 includes a first base 310 for connecting with a lobster buckle assembling machine. A first feeding cylinder 320 is connected to the first base 310 through a plurality of plate bodies.

The two clamping arms 351 are inclined by using the groove walls of the groove body, so that the gap distance between them can be adjusted when lifting in the groove body, thereby realizing the clamping and feeding of the torsion spring 600.

[0039] It is understandable that the lifting, displacement of the clamping part 350, and the adjustment of the clamping gap can all adopt the guide rail structure in the existing technology and will not be elaborated here.

[0040] The first bending assembly 400 includes a second base 410 for connecting with a lobster buckle assembling machine. A first driving cylinder 420 is provided on the second base 410.

The piston of the second bending cylinder 520 penetrates through the second connecting plate 360 and is connected to a second bending rod 540. The second bending rod 540 is hinged to the second connecting plate 360. Driven by the second bending cylinder 520, it swings to approach or move away from the fixed mold on the lobster buckle assembling machine, and cooperates with the first bending rod 450 to bend the torsion spring 600 on the clamping member 350.

[0043] Connectors 530 are provided at both ends of the bottom of the first connecting plate 510. The connectors 530 are in a U shape. The second bending rod 540 is hinged to the two connectors 530. And one end of the second bending rod 540 away from the fixed mold on the lobster buckle assembling machine is connected to the second bending cylinder 520, and the other end extends above the fixed mold on the lobster buckle assembling machine through the connector 530.

[0044] The working principle of a kind of feeding mechanism for the lobster buckle torsion spring provided by this embodiment:

[0045] First of all, the vibrating disk 100 operates to convey the torsion spring 600 to the receiving member 200;

[0046] Then, the clamping member 350 of the feeding assembly 300 clamps the torsion spring 600 on the receiving member 200 under the combined action of the first feeding cylinder 320, the second feeding cylinder 330 and the adjusting cylinder 340 and transfers it above the fixed mold of the lobster buckle assembling machine;

[0047] Then, the first driving cylinder 420 of the first bending assembly 400 drives the first bending cylinder 430, the bending pull block 440 and the first bending rod 450 to approach the fixed mold of the lobster buckle assembling machine, so that the first bending cylinder 430 pushes the bending pull block 440 to displace, driving the first bending rod 450 to approach and abut against the torsion spring 600 located above the fixed mold of the lobster buckle assembling machine, and bending the extended part of one end of it;

[0048] At the same time, the second bending cylinder 520 of the second bending assembly 500 pushes the end of the second bending rod 540 to descend, and the other end rises to abut against the torsion spring 600 above the fixed mold of the lobster buckle assembling machine, and bends the extended part of the other end of it, so that the torsion spring 600 can be fixed on the fixed mold or the door seal of the lobster buckle assembling machine by its own elasticity for subsequent lobster buckle assembly.

[0049] A feeding mechanism for a lobster buckle torsion spring provided in this embodiment, compared with the prior art, by adopting a feeding component 300 and a first bending component 400 provided on the side of the material receiving part 200, and a second bending component 500 provided at the bottom of the feeding component 300. During actual use, the existing torsion spring 600 of the lobster buckle is placed into the vibrating bowl 100, the vibrating bowl 100 supplies the torsion spring 600 to the material receiving part 200, the feeding component 300 transfers the torsion spring 600 in the material receiving part 200 above the fixed mold of the lobster buckle assembling machine, and the first bending rod 450 of the first bending component 400 and the second bending rod 540 of the second bending component 500 cooperate to bend the extended parts at both ends of the torsion spring 600 so that it is fixed on the fixed mold of the lobster buckle assembling machine in cooperation with the door seal of the lobster buckle. Compared with the prior art, only the extended parts at both ends of the torsion spring 600 need to be bent, without overall bending forming, improving the feeding efficiency of the torsion spring 600, and thus improving the assembling efficiency of the lobster buckle.
