Description

Technical Field

[0001] This utility model relates to the technical field of watch strap processing equipment, and in particular to a high-precision beaded strap assembly machine. Background Technology

[0002] Metal watch bands are made up of multiple beads connected together. Cotter pins and steel pins of different lengths are inserted between the beads at different positions. In current watch band assembly equipment, the beads are fed into a conveyor device, which controls the position of the beads and transports them to the pin insertion mechanism for assembly of the steel pins and cotter pins. This setup requires a conveying and assembly of the steel pins or cotter pins after each bead is picked up, and the watch band can only be assembled after multiple conveyings, resulting in low work efficiency. Moreover, the beads may shift during the conveying process after being placed, affecting the assembly. Therefore, improvements are needed. Utility Model Content

[0022] The beneficial effects of this utility model are as follows:

[0023] 1. In the bead-guided positioning and limiting mechanism of this design, the empty carrier is positioned by the first carrier positioning seat. When the beads are being fed, the first Y-axis drive devices of the two sets of Y-guided alignment devices control the Y-guided alignment blocks to move to one side of the carrier. In this state, the two Y-guided alignment blocks are distributed front and back above the carrier to limit the front and back direction when the beads are being fed. The X-guided alignment device controls the left guide block to move to the right through the first X-axis drive device to limit the left end when the beads are being fed. At this time, the left guide block, the two Y-guided alignment blocks, and the positioning protrusion structure of the carrier form a space for placing the beads. The bead-carrying robot arm then transports the beads to this position. After the bead-carrying robot arm takes the beads from the bead feeding mechanism and transports them, the first X-axis drive device controls the left guide block to move to the left. A distance equal to the width of a bead is provided, creating a space for bead placement between the left guide block, the two Y-guide blocks, and the bead to its right, awaiting the loading of the next bead until the carrier is full. This design ensures the beads function as guides during loading, resulting in high positional accuracy. After loading, adjacent beads are connected by a concave-convex structure, and the carrier's positioning protrusions also limit the movement of each bead, preventing them from shifting. After the Y-guide and X-guide devices are reset, the carrier is transported by the carrier transport mechanism to the second carrier positioning seat with the bead pressing and pushing needle mechanism. This design allows all beads to be loaded and positioned onto the carrier in one go, awaiting subsequent assembly of the steel needles and hairpins in one process, avoiding multiple rounds of loading and assembly, thus improving work efficiency.

[0024] 2. The clamping device of the carrier handling mechanism has a carrier clamping cylinder and a pressing cylinder. During the handling process, the carrier clamping cylinder clamps the carrier, while the pressing cylinder presses down all the dial beads on the carrier to prevent the dial beads from shifting during the handling process.

[0025] 3. In the bead pressing and pushing mechanism, after the carrier transport mechanism moves the carrier filled with beads from the first carrier positioning seat to the second carrier positioning seat, the pressing device presses all the beads on the carrier from above. After the two sets of pushing devices are filled with steel needles and hair clips, they push the steel needles and hair clips to one side of the second carrier positioning seat, so that all the steel needles and hair clips can be assembled into the beads, completing the assembly of the watch strap. The work efficiency is high. Attached Figure Description

[0041] The bottom of the carrier 6 is provided with two positioning holes distributed on the left and right, which are used for positioning when the carrier 6 is placed to improve the positioning accuracy.

[0042] The carrier 6 is made of magnetic material and is used to be magnetically attracted and fixed during placement to improve stability.

[0043] like Figure 4-6 As shown, the beaded guide and limiting mechanism 7 includes a first vehicle positioning seat 71, an X-axis guide alignment device 72, and two sets of Y-axis guide alignment devices 73; the first vehicle positioning seat 71 is used to position the vehicle 6; the X-axis guide alignment device 72 is located on the left side of the first vehicle positioning seat 71, including a first X-axis drive device 721 and a left guide block 722 installed at the power output end of the first X-axis drive device 721; the two sets of Y-axis guide alignment devices 73 are symmetrically distributed on the front and rear sides of the first vehicle positioning seat 71, including a first Y-axis drive device 731 and a Y-axis guide block 732 installed at the power output end of the first Y-axis drive device 731;

[0044] The left guide block 722 can slide left and right between the two left limiting protrusions 611 and between the two rows of separating protrusions 612. After the empty carrier 6 is positioned on the first carrier positioning seat 71, it waits for the beads to be loaded. During the bead loading process, the first Y-direction drive device 731 of the two sets of Y-direction guide devices 73 controls the Y-direction guide block 732 to move towards one side of the carrier 6. In this state, the two Y-direction guide blocks 732 are distributed front and back above the carrier 6 to limit the front and back direction when loading the beads. The X-direction guide device 72 controls the left guide block 722 to move to the right through the first X-direction drive device 721 to limit the left end when loading the beads. At this time, the left guide block 722, the two Y-direction guide blocks 732 and the right limiting protrusion 613 form a space for placing beads, waiting for the beads to be loaded. After the beads are loaded, the first X-direction drive device 721 controls the left guide block 722 to move to the right. The left guide block 722 moves to the left a distance equal to the width of a bead, creating a space for bead placement between the left guide block 722, the two Y-guide blocks 732, and the bead on its right, awaiting the loading of the next bead until the carrier 6 is full. This design ensures that the beads have a guiding function during loading, resulting in high positional accuracy. After loading, adjacent beads are connected to each other through a concave-convex structure, and the positioning protrusion structure 61 of the carrier 6 also limits the position of each bead, preventing them from shifting. After the Y-guide aligning device 73 and the X-guide aligning device 72 are reset, the carrier transport mechanism 9 moves the carrier 6 to the second carrier positioning seat 81 of the bead pressing and pushing needle mechanism 8. This design uses a one-time loading and positioning of all beads onto the carrier 6, awaiting subsequent assembly of the steel needle and hairpin, avoiding multiple loading and assembly processes and improving work efficiency.
