Description

Technical Field

[0001] This utility model relates to the technical field of watch strap processing equipment, and in particular to a bead guide and limiting 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. To ensure assembly accuracy, the equipment needs to transport and assemble the steel pins or cotter pins after each bead is picked up. This requires multiple transports to complete the watch band assembly, resulting in low work efficiency. If all beads need to be picked up at once for assembly, a high-precision positioning and guiding limit mechanism needs to be designed to improve the overall assembly efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a beaded guiding and limiting 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-guided positioning mechanism includes a carrier, a carrier positioning seat, an X-axis guiding device, and two sets of Y-axis guiding devices. The carrier is provided with positioning protrusions for positioning all beads on the watch strap. The carrier positioning seat is used for positioning the carrier. The X-axis guiding device is located on the left side of the carrier positioning seat and includes an X-axis driving device and a left guiding block installed at the power output end of the X-axis driving device. The two sets of Y-axis guiding devices are symmetrically distributed on the front and rear sides of the carrier positioning seat and include a Y-axis driving device and a Y-axis guiding block installed at the power output end of the Y-axis driving device.

[0006] Further description of this utility model: the positioning protrusion structure of the vehicle includes two left limiting protrusions formed front to back on the left end of the top of the vehicle, two right limiting protrusions formed front to back on the right end of the top of the vehicle, and two rows of separating protrusions distributed left to right between the left and right limiting protrusions; the two rows of separating protrusions are symmetrically arranged front to back; the left guide block can slide left and right between the two left limiting protrusions and between the two rows of separating protrusions.

[0007] 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.

[0008] In a further description of this utility model, the carrier is made of magnetic material; an electromagnet is installed on the carrier positioning seat.

[0009] In a further description of this utility model, the right end face of the left guide block is a first guide slope that slopes from the upper left to the lower right; the two Y-guide blocks are provided with a second guide slope that slopes from top to bottom toward the vehicle positioning seat.

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

[0011] The carrier in this design is positioned by a carrier positioning seat. During bead loading, the Y-axis drive devices of the two sets of Y-axis alignment devices control the Y-axis alignment blocks to move to one side of the carrier. In this state, the two Y-axis alignment blocks are distributed front and back above the carrier to limit the front and back direction of bead loading. The X-axis alignment device controls the left guide block to move to the right through the X-axis drive device to limit the left end of the bead loading. At this time, the left guide block, the two Y-axis alignment blocks, and the positioning protrusion structure of the carrier form a space for bead placement. When the bead is loaded to this position, it falls into this space during the loading process. After loading one bead, the X-axis drive device controls the left guide block to move to the left. The distance of one bead width creates 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 enables the beads to function as guides during loading, ensuring high positional accuracy. After loading, adjacent beads are connected to each other through a concave-convex structure, and the positioning protrusions of the carrier also limit the movement of each bead, preventing them from shifting. After the Y-guide and X-guide devices are reset, the carrier awaits the subsequent assembly process of the steel pin hair clip. This design can accurately complete the loading and positioning of all beads in the watch strap, providing a foundation for subsequent assembly and thus improving overall assembly efficiency.

[0017] The present invention will be further described below with reference to the accompanying drawings:

[0018] like Figure 1-5 As shown, a beaded guide and limiting mechanism includes a carrier 6, a carrier positioning seat 71, an X-guide alignment device 72, and two sets of Y-guide alignment devices 73.

[0019] The carrier 6 is provided with a positioning protrusion structure 61 for positioning all the beads of the watch strap; the positioning protrusion structure 61 of the carrier 6 includes two left limiting protrusions 611 formed front to back at the top left end of the carrier 6, two right limiting protrusions 613 formed front to back at the top right end of the carrier 6, and two rows of separating protrusions 612 formed left to right between the left limiting protrusions 611 and the right limiting protrusions 613; the two rows of separating protrusions 612 are symmetrically arranged front to back; the two separating protrusions 612 and the two right limiting protrusions 613 at the rightmost end are used to limit the rightmost bead, the two separating protrusions 612 and the two left limiting protrusions 611 at the leftmost end are used to limit the leftmost bead, the beads at the middle position are respectively limited by two adjacent rows of separating protrusions 612, and the groove formed between the two right limiting protrusions 613 is used to position the protruding structure of the rightmost bead.

[0020] The carrier positioning seat 71 is used to position the carrier 6; the bottom of the carrier 6 is provided with two positioning holes distributed on the left and right, and the carrier positioning seat 71 is provided with positioning pins 01 that cooperate with the positioning holes. When the carrier 6 is placed in, it is positioned by the positioning pins 01 cooperating with the positioning holes of the carrier 6, thereby improving the positioning accuracy.

[0021] The carrier 6 is made of magnetic material, and an electromagnet 02 is installed on the carrier positioning seat 71. When the carrier 6 is placed in, the carrier is fixed by magnetic attraction through the electromagnet 02.

[0022] The X-axis alignment device 72 is located on the left side of the vehicle positioning seat 71, including an X-axis drive device 721 and a left alignment block 722 installed at the power output end of the X-axis drive device 721; the two sets of Y-axis alignment devices 73 are symmetrically distributed on the front and rear sides of the vehicle positioning seat 71, including a Y-axis drive device 731 and a Y-axis alignment block 732 installed at the power output end of the Y-axis drive device 731.

[0023] 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 placed on the carrier positioning seat 71 and positioned, it waits for the beads to be loaded. During the bead loading process, the Y-direction drive devices 731 of the two sets of Y-direction guiding devices 73 control the Y-direction guiding blocks 732 to move towards one side of the carrier 6. In this state, the two Y-direction guiding blocks 732 are distributed front and back above the carrier 6 to limit the front and back direction during bead loading. The guiding device 72 controls the left guiding block 722 to move to the right via the X-axis drive device 721, which limits the left end of the bead during feeding. At this time, the left guiding block 722, the two Y-axis guiding blocks 732, and the right limiting protrusion 613 form a space for bead placement, waiting for bead feeding. After the bead is fed, it is positioned within this placement space with high positioning accuracy. The X-axis drive device 721 then controls the left guiding block 722 to move to the left by a distance equal to the width of a bead, so that the left guiding block 722... 2. A space for placing beads is formed between the two Y-guide alignment blocks 732 and the beads on their right, waiting for the next bead to be loaded until the carrier 6 is full of beads. This setting enables the beads to play a guiding role during the loading process, with high positional accuracy. After loading, adjacent beads are connected to each other through concave and convex structures, and the positioning protrusion structure 61 of the carrier 6 also limits the position of each bead, making it difficult for the beads to move. After the Y-guide alignment device 73 and X-guide alignment device 72 are reset, the carrier 6 is removed for subsequent processes to prepare for the assembly of steel needles and hair clips. This design uses all beads to be loaded onto the carrier 6 in sequence and positioned at one time, waiting for the subsequent processes to assemble steel needles and hair clips at once, avoiding multiple rounds of loading and organizing processes, and improving work efficiency. Since the subsequent processes also need to assemble steel needles and hair clips directly on the carrier 6, after the carrier 6 is installed with beads, the front and back sides of the beads are not blocked, and steel needles and hair clips can be directly inserted between the beads from the front and back sides.

[0024] The right end face of the left guide block 722 is a first guide slope that slopes from the upper left to the lower right; the two Y guide blocks 732 are provided with a second guide slope that slopes from top to bottom toward the carrier positioning seat 71 at opposite ends. The setting of the first guide slope and the second guide slope improves the guiding and positioning effect during the bead feeding process.

[0025] The above description does not limit the technical scope of this invention. Any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this invention shall still fall within the scope of the technical solution of this invention.
