Description

Technical Field

[0001] This utility model relates to the technical field of watch strap processing equipment, and in particular to a bead pressing and pushing mechanism. 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 steel pins and cotter pins. This setup means that after each bead is picked up, the steel pins or cotter pins need to be transported and assembled once. The watch band can only be assembled after multiple transports, resulting in low work efficiency. In order to improve work efficiency, a mechanism that can assemble all steel pins and cotter pins into the watch band at once needs to be designed. Utility Model Content

[0003] The purpose of this invention is to provide a beaded pressing and pushing needle mechanism to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A bead-pressing and push-pin mechanism includes a carrier, a carrier positioning seat, a pressing device, and two sets of push-pin devices. The carrier is provided with a positioning protrusion structure for positioning all beads of a watch strap. The positioning protrusion structure of the carrier includes two left limiting protrusions formed at the left end of the top of the carrier, two right limiting protrusions formed at the right end of the top of the carrier, and two rows of separating protrusions distributed between the left and right limiting protrusions. The two rows of separating protrusions are symmetrically arranged. The carrier positioning seat is used to position the carrier. The pressing device is used to press the beads on the carrier from above. The two sets of push-pin devices are symmetrically distributed on the front and rear sides of the carrier positioning seat, and are used to receive all the steel pins and hairpins of a watch strap assembly and push them to one side of the carrier positioning seat.

[0006] In a further description of this utility model, the pressing device is located on the right side of the carrier positioning seat and includes a support, an X-axis drive device, a Z-axis drive device, and a pressing block; the X-axis drive device is mounted on the support and its power output end is connected to the Z-axis drive device; the power output end of the Z-axis drive device is connected to the pressing block.

[0007] Further description of this utility model: the needle-pushing device includes a first Y-axis driving device, a first mounting plate, a steel needle carrier plate, a second Y-axis driving device, a second mounting plate, and a needle-pushing plate; the power output end of the first Y-axis driving device is connected to the first mounting plate; the steel needle carrier plate is fixed on the first mounting plate and located on the side close to the carrier positioning seat; the steel needle carrier plate is provided with a plurality of steel needle placement slots distributed left and right; the second Y-axis driving device is mounted on the first mounting plate and its power output end is connected to the second mounting plate; the needle-pushing plate is mounted on the second mounting plate; the bottom of the needle-pushing plate is provided with a pushing protrusion that cooperates with the steel needle placement slots, and the pushing protrusion is used to push the steel needles or hairpins on the steel needle carrier plate toward the carrier positioning seat.

[0008] In a further description of this utility model, the bottom of the carrier is provided with two positioning holes distributed on the left and right; the positioning seat of the carrier is provided with positioning pins that cooperate with the positioning holes.

[0009] In a further description of this utility model, the carrier is made of magnetic material; an electromagnet is installed on the carrier positioning seat.

[0010] The beneficial effects of this utility model are as follows:

[0011] All the beads of the watch strap are placed on the carrier in the previous process and are limited by the positioning protrusion structure of the carrier. After positioning, the protrusion structure of the rightmost bead is limited by the groove between the two right limiting protrusions. Adjacent beads are also positioned by the cooperation of the concave and convex structure. The separating protrusions further limit the left and right sides of each bead. Therefore, after the beads are placed, the stability is high and they are not easy to move. Moreover, after the beads are placed, the front and back sides of the beads are not blocked. The two sets of push pin devices can directly push the steel pins and hair clips into the beads from the front and back sides for assembly. After the carrier is transported to the carrier positioning seat, the pressing device presses all the beads on the carrier from above. After the two sets of push pin devices are full of steel pins and hair clips, they push the steel pins and hair clips to one side of the carrier positioning seat. This allows all the steel pins and hair clips to be assembled into the watch strap, completing the watch strap assembly. The work efficiency is high. Attached Figure Description

The beads in the middle position are limited by two adjacent rows of dividing protrusions 612. The groove formed between the two right limiting protrusions 613 is used to position the protruding structure of the rightmost bead. All the beads of the watchband are placed on the carrier in the previous process and limited by the positioning protrusion structure of the carrier. After positioning, the protruding structure of the rightmost bead is limited by the groove between the two right limiting protrusions. Adjacent beads are also positioned by the cooperation of the concave and convex structure. The dividing protrusions further limit the left and right sides of each bead. Therefore, after the beads are placed, the stability is high and it is not easy to move. Moreover, after the beads are placed, the front and back sides of the beads are not blocked, leaving space for the assembly of the steel pin and the hair clip.

The needle plate 836 is installed on the second mounting plate 835; the bottom of the needle pusher plate 836 is provided with a pusher protrusion 8361 that cooperates with the steel needle placement groove 8331. The pusher protrusion 8361 is used to push the steel needles or hairpins on the steel needle carrier plate 833 toward the carrier positioning seat 81. In this design, a set number of short steel needles, long steel needles and hairpins are placed in the front needle pusher device 83 and pressed into the beads from the front. A set number of short steel needles and long steel needles are placed in the rear needle pusher device 83 and pressed into the beads from the rear. All beads can be assembled into a watch strap with just one press. After assembly, the carrier 6 can be removed in the subsequent process.

[0023] The bottom of the carrier 6 is provided with two positioning holes distributed on the left and right; the carrier positioning seat 81 is provided with a positioning pin 01 that cooperates with the positioning hole to improve the positioning effect.

[0024] The carrier 6 is made of magnetic material; an electromagnet 02 is installed on the carrier positioning seat 71, and the carrier 6 is fixed by magnetic attraction through the electromagnet 02, thereby improving the stability after installation.
