Description

Technical Field

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

[0002] There is a stainless steel watch band where the first half consists of beads connected sequentially from largest to smallest. Steel pins are inserted on both sides to assemble the beads. Due to the different sizes of the beads, two different lengths of steel pins are needed for this section. The second half consists of beads of the same size connected together. Adjacent beads are assembled using cotter pins inserted from one side. After the steel pins and pins are assembled, they need to be riveted for fixation. Previously, the assembly of the steel pins and pins was done manually, but this assembly is difficult. It requires sequentially piecing the beads together and then using steel pins and pins of different specifications, which is not only inefficient but also prone to errors and cannot meet production needs.

[0032] like Figure 2-4 as well as Figure 9As shown, the clamping and conveying mechanism 2 is used to clamp beads and control their forward and backward movement. It includes a Y-axis drive module 21, a mounting base 22, a support base 23, a first stop device 24, a pusher device 25, and a limiting device 26. The Y-axis drive module 21 is mounted on the chassis 1, and its power output end is connected to the mounting base 22. The pusher device 25, support base 23, and limiting device 26 are sequentially mounted on the mounting base 22 from back to front.

The bead feeding mechanism 3 feeds the beads to the rear position of the support base 23. At this time, the beads are located between the push block 253 and the stop block 242. The stop block 242 is in a raised state, limiting the beads. The first Z-axis cylinder 241 controls the stop block 242 to move downward to release the limitation on the beads. The first Y-axis drive device 252 controls the push block 253 to move forward. The push block 253 pushes the beads forward and pushes the beads to the limit plate 264 for passage.

For each bead fed in, the second Y-axis drive device 262 controls the limiting plate 264 to move forward by the width of one bead, and the first Y-axis drive device 252 controls the pusher block 253 to move forward. After resetting, the first Z-axis cylinder 241 also controls the stop block 242 to reset upwards, preventing the bead from rebounding and limiting the rear side of the bead. The second bead is then fed again between the pusher block 253 and the stop block 242, and the pushing step is repeated to push the bead to the rear side of the first bead. After the two beads are loaded and positioned, the Y-axis drive module 21 controls the mounting base 22 to be transported to the steel needle assembly position. The left steel needle assembly module 4 and the right steel needle assembly module 5 assemble the corresponding steel needles between the two beads and fix them with rivets. After completion, the third bead is positioned and the steel needle is assembled. This process of bead feeding and steel needle assembly is repeated. In this design, the length of the first six beads gradually decreases from front to back. The first three beads are connected using long steel needles, while the last three are connected using short steel needles. The beads at the rear are of the same size and are connected using hairpins. Once all beads are fed and the steel needles and hairpins are assembled, the assembly is complete. The beads are then transported to the unloading mechanism 6 and unloaded.

The spring 2633 applies a backward elastic pressure to the slide 2632, and the limiting plate 264 is fixed on the slide 2632, thereby indirectly applying a backward elastic pressure to the limiting plate 264.

[0035] The limiting device 26 further includes a pressing assembly 265; the pressing assembly 265 includes a connecting seat 2651, a third Y-axis driving device 2652, a second Z-axis cylinder 2653, and an upper pressing block 2654; the connecting seat 2651 includes two support plates and a top plate; the lower ends of the two support plates are fixedly connected to the bottom plate 261; the top plate is fixed to the upper ends of the two support plates; the top plate is located above the limiting plate 264; the third Y-axis driving device 2652 is mounted on the top plate and its power output end is connected to the second Z-axis cylinder 2653; the power output end of the second Z-axis cylinder 2653 is connected to the upper pressing block 2654.

[0046] In the clamping and transferring mechanism 2, the mounting base 22 is controlled to move backward by the Y-axis drive module 21. This station is the bead receiving station. The bead feeding mechanism 3 feeds the beads into the clamping and transferring mechanism 2.

The Y-axis drive module 21 controls the beads to be transported forward between the first pusher mechanism 43 and the second pusher mechanism 53. This station is the assembly station.

After insertion, the Y-axis drive module 21 controls the beads to be transported backward to the first riveting mechanism 44 and the second riveting mechanism 54. This station is the riveting station. The steel needles are riveted and fixed on the beads by the first riveting mechanism 44 and the second riveting mechanism 54, completing the assembly between the two beads.
