Description

Among them, earrings have many different styles, one of which is to match a round bead at the lower end of the earring, such as pearl earrings, which can bring a round, noble and elegant decoration effect to the wearer. The processing of this kind of earring with beads at least includes the following basic processes: bending the metal wire into a circle, attaching the two ends of the circle together to form a closed circular ring; obtaining a round bead, tightly attaching the round bead and the circular ring together, and welding the round bead and the circular ring into one body by a welding gun and a welding rod, thereby obtaining the finished product of the earring with beads.

[0003] The processing of such jewelry often relies on personnel in the production workshop to operate by hand. Since the size of the circular ring and the round bead is very small, both the bending process of the circular ring and the attachment and welding process of the round bead require the production personnel to concentrate for a long time, which is extremely tiring and laborious.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0036] The present application discloses an automatic round bead welding machine for processing and preparing a bead earring. In order to facilitate understanding of the working principle of the present application, the structure of the bead earring is described as follows: Figure 1 The bead earring mainly includes a circular ring 2 and a round bead 3, the circular ring 2 is made by punching the linear metal wire 1 into a circular shape, and the round bead 3 is a beaded ornament (such as a pearl or a bead made of other materials, etc.), the round bead 3 and the circular ring 2 are welded and fixed together to obtain the finished product of the ornament.

[0037] Referring to Figures 2-3 , the automatic round bead welding machine comprises a wire guide mechanism, a round punching mechanism, a first clamping jaw mechanism 100, a second clamping jaw mechanism 110, a welding wire feeding mechanism 120, a welding mechanism 130, and a control module 140.

[0038] The wire guide mechanism is used for horizontally conveying the linear metal wire 1, and the metal wire 1 is used as the processing raw material of the circular ring 2 part of the ornament.

[0039] The round punching mechanism is used for punching the metal wire 1 into a circular ring 2 structure. Referring to Figures 4-9The rounding mechanism is located at the rear end of the wire feeding direction of the conductor mechanism, and includes: a cutting device 40, a rounding base 50, a base drive source 60, a stamping column 70, a stamping column drive source 80, and a pressing device 90. (See attached image for details.) Figure 5 , Figure 7 , Figure 8 The circular base 50 includes a pair of horizontally movable left bases 51 and right bases 52. Each of the left and right bases 51 and 52 has a semi-circular groove 53 on its opposite side. The left and right bases 51 and 52 can be fitted together or separated. When the left and right bases 51 and 52 are fitted together, the two semi-circular grooves 53 merge to form a circular stamping groove 54. Of course, the circular stamping groove 54 is not a completely closed circle; its top has a small opening for the pressing device 90 to operate. The pressing principle is described below. The base drive source 60 can be a cylinder used to drive the opening and closing of the left and right bases 51 and 52. See [link to relevant documentation]. Figure 6 See also Figure 5 and Figure 7 The stamping column 70 is positioned above the circular stamping base 50. A straight metal wire 1 is conveyed to the top of the circular stamping base 50, with the stamping column 70 located above the metal wire 1. A stamping drive source drives the stamping column 70 to move up and down, allowing the stamping column 70 to enter or exit the circular stamping groove 54. When the stamping column 70 presses down, the straight metal wire 1 is pressed into the circular stamping groove 54. The outer circumference of the stamping column 70 matches the circular stamping groove 54, so that when the left base 51 and the right base 52 are in contact with each other, the semi-circular grooves 53 on both sides will grip the stamping column 70.

[0040] See Figures 4-7 The pressing device 90 includes a pressing claw 91 and a pressing claw drive source 92. The end structure of the pressing claw 91 is adapted to fit against the outer periphery of the stamping column 70. Specifically, the lower end of the pressing claw 91 is provided with an arc-shaped pressing groove 911, the curvature of which matches the curvature of the outer periphery of the stamping column 70. The pressing claw drive source 92 is used to drive the pressing claw 91 to perform linear lifting and lowering movements, thereby causing the pressing claw 91 to fit against or disengage from the surface of the stamping column 70. The pressing claw drive source 92 can be implemented using a cylinder.

[0041] See Figure 10 and Figure 12 The first gripper mechanism 100 is used to grip and remove the stamped ring 2 from the stamping column 70 and transfer it to the welding station. The second gripper mechanism 110 is used to grip the ball 3 and transfer it to the welding station. (See reference...) Figures 10-11, the welding station is further provided with a welding wire feeding mechanism 120 and a welding mechanism 130, the welding wire feeding mechanism 120 is used for feeding the welding wire required in the welding process, and the welding mechanism 130 is used for welding and fixing the circular ring 2 and the circular bead 3 together. The welding mechanism 130 comprises a welding gun 131 and a welding gun driving source 132, the welding gun driving source 132 can be realized by a cylinder and is used for driving the welding gun 131 to move along a predetermined welding track and complete welding on the welding spot.

[0042] The control module 140 is an electrical control system of the device, which is electrically connected or communicatively connected to each action mechanism and is used for controlling each action mechanism to act according to certain flow logic, so as to sequentially complete each process. The electrical control principle is a technology known in the art and is not improved in the present application, and thus will not be described herein.

[0043] In work, referring to Figure 5 and Figure 7 , the wire mechanism delivers the linear metal wire 1 to the side of the circular punching mechanism, and the horizontal height of the metal wire 1 is on the top of the circular punching base 50. The cutting device 40 acts, and the cutting knife 41 is pressed to cut the metal wire 1. The cut metal wire 1 stays on the top of the circular punching base 50, and the cut metal wire 1 is a workpiece to be punched into a circle. The stamping column 70 is located above the metal wire 1, and the left base 51 and the right base 52 of the circular punching base 50 are in a state of being separated from each other at the beginning. The stamping column 70 moves downward to press the linear metal wire 1 into the two semicircular grooves 53, the left base 51 and the right base 52 move towards the middle and close to each other to form a circular stamping groove 54, and the metal wire 1 is tightly pressed between the stamping column 70 and the circular stamping groove 54 to force the metal wire 1 to form a circular ring 2 structure.

[0044] Since the two ends of the metal wire 1 are cut by the cutting blade, they are relatively smooth and sharp, not easy to bend and fit, and the two ends of the circular ring 2 are prone to be warped. Therefore, a small opening is left on the top of the circular stamping groove 54 for the entry of the edge presser 91. The edge presser 91 moves downward into the circular stamping groove 54 and slightly presses the two end edges of the circular ring 2 against the stamping column 70, so that the two ends of the circular ring 2 are also well bent.

[0045] After the above circular ring 2 stamping process is completed, the left base 51 and the right base 52 of the circular punching base 50 are re-opened and separated, the stamping column 70 moves upward to exit the circular stamping groove 54, referring to Figure 11, the first clamping jaw mechanism 100 clamps the ring 2 from the stamping column 70 and moves it to the welding station. The second clamping jaw mechanism 110 clamps the ball 3 in the tray and moves it to the welding station. The first clamping jaw mechanism 100 and the second clamping jaw mechanism 110 cooperate to abut the ring 2 and the ball 3 against each other, while the welding wire feeding mechanism 120 feeds a small section of the welding wire, the welding gun 131 moves along the predetermined trajectory, and the flame at the end of the welding gun 131 welds the ring 2 and the ball 3 together, thereby obtaining the finished product of the earring with a ball.

[0046] The present application simultaneously realizes the feeding of the metal wire 1, the cutting of the metal wire 1, the stamping of the ring 2, the clamping and relative position fixing of the ring 2 and the ball 3, and the welding forming, which is equivalent to realizing the automation of the whole process of processing the earring with a ball, completely eliminating the manual operation of the production personnel, saving a large amount of manpower and cost, and greatly improving the production efficiency. The shape of the ring 2 punched by the punching mechanism is stable and consistent, and the closure degree is good.

[0048] Specifically, in order to avoid the metal wire 1 from easily producing radial shaking and thereby affecting the cutting quality and the stamping quality, referring to Figure 8 and Figure 5 , a limiting groove 55 is formed on the top of the left base 51 and the right base 52, which extends along the conveying direction of the metal wire 1 and is adapted to accommodate the lower part of the metal wire 1, thereby playing a guiding and limiting role on the metal wire 1.
