Description

Technical Field

[0001] The utility model relates to the technical field of watch strap processing, in particular to a full-automatic watch strap laser water nozzle cutting machine. Background Art

[0002] A watch, or wristwatch, is an instrument worn on the wrist to measure / display time. A watch is usually made of leather, rubber, nylon cloth, stainless steel and other materials to make a strap. The strap is a general term for the effective part of the watch that fixes the wrist. There are many different strap materials, including silicone straps.

[0003] When the silicone strap is processed and formed, a sprue will be left on the strap. The so-called sprue refers to the excess material left on the silicone strap during hydraulic forming. In order to ensure the integrity and good appearance of the silicone strap, the remaining sprue needs to be cut and removed after processing. At present, many ways to remove the sprue still use a simple sprue cutting fixture for manual cutting operation, that is, the strap after hydraulic forming is taken by hand and placed in a simple sprue cutting fixture to cut and remove the sprue, and then the product is picked up from the sprue cutting fixture and put into the next process, which makes the cutting operation slow and inefficient. Due to the rough manual operation, the sprue cutting is uneven, resulting in a high product defect rate. In order to improve the yield of the product, a laser sprue cutting machine is now also used to cut the sprue. The straps are mainly placed on the fixture one by one by hand, and then cut by the laser sprue cutting machine. Although this method can improve the yield of the cut product, the manual placement is inefficient, easy to misplace, and the manual labor intensity is high and the cost is high. In response to this problem, the inventor designed a fully automatic strap laser sprue cutting machine. Utility Model Content

[0015] 1. The utility model provides a fully automatic watch strap laser water nozzle cutting machine, which is composed of a feeding tray mechanism, a loading and unloading robot, a rotating mechanism and a laser water nozzle cutting machine body. The overall structure is simple and the design is reasonable. The loading and unloading robot is used to adsorb the watch strap on the feeding tray mechanism and place it on the rotating mechanism. The laser water nozzle cutting machine body removes the water nozzle of the watch strap on the rotating mechanism. The watch strap after the water nozzle is removed is adsorbed by the loading and unloading robot and placed on the feeding tray mechanism.

During operation, the tray lifting mechanism at one feeding station lifts the stacked material tray to keep it away from the first transmission belt and the second transmission belt. At the same time, the output ends of the two clamping cylinders at one feeding station drive the clamping plates to extend to clamp the stacked material trays, and leave the bottom material tray on the lifting tray at one feeding station. At this time, the lifting tray moves downward under the action of the servo motor until the material tray on the lifting tray contacts the first transmission belt and the second transmission belt, and then the material tray follows the first transmission belt and the second transmission belt The belt arrives at feeding station two. After the position sensor at feeding station two senses the material tray, it sends a signal to the material blocking cylinder between feeding station two and feeding station three. After receiving the signal, the material blocking cylinder drives the material blocking plate to extend and blocks the material tray, so that the material tray is at feeding station two. Similarly, an empty material tray is placed at feeding station three manually. The material blocking cylinder between feeding station three and feeding station four blocks the empty material tray to prevent it from moving backwards. At this time, the loading and unloading robot puts the material tray at feeding station two. The strap on the material tray is adsorbed and moved to the rotating mechanism, and at the same time, the strap without the sprue on the rotating mechanism is moved and placed in the empty material tray above feeding station three, and this is repeated until the strap on the material tray at feeding station two is taken out and the empty material tray above feeding station three is filled with straps. At this time, the material blocking cylinder drives the material blocking plate to reset, and the empty material tray arrives at feeding station three, and the material tray without the sprue strap arrives at feeding station four.

Since one end of the watch strap is thick and the other end is thin, in order to ensure the stability of the stacking, the material trays 113 to be de-watered are manually stacked one in front and one in back during stacking. Finally, the stacked material trays 113 to be de-watered are placed at the feeding station 12 of the feeding tray mechanism 1, and are limited by the material blocking rack 114 at the feeding station 12. An empty material tray 113 is placed at the feeding station 3 14, which is mainly used to place the watch strap after the nozzle is removed.
