The working principle of the present invention is as follows: the displacement cylinder 64 works through the second connecting plate 66 and the push base 523 to drive the whole device to move a certain distance toward the heat shrinkable tube 10; as shown in Figures 10 to 11, the steel needle 8 is placed on the On the slope 1141 in the warehouse 11, turn the adjustment knob 144 to make the adjustment plate 141 to the proper position; since the slope 1141 is inclined to the direction of the support plate 115, the steel needle 8 enters the steel needle outlet 116 along the slope 1141, and the pushing The cylinder 41 moves downwards and drives the material distribution plate 121 to move downwards by pushing the cylinder shaft 411 to separate a steel needle into the cavity 1331, and the conveying steel needle cylinder shaft 1321 of the conveying steel needle cylinder 132 pushes the needle to push The plate 133 sends the steel needle 8 to the two U-shaped grooves 31 of the workpiece carrier 3 through the through hole 1151 (as shown in Figure 3 and Figure 4), and the steel needle 8 falls to the bottom of the U-shaped groove 31 under the action of its own gravity The finger cylinder 2121 works to clamp the two hot-melt pipes 9 through the first clamping block 2122 and the second clamping block 2123, and the hot-melt pipe conveying cylinder 211 works, and drives the finger cylinder 2121 to clamp through the guide slider 213 Two heat-melt pipes 9 are delivered to the two U-shaped grooves 31 of the workpiece carrier 3 through the round pipe 216 and the round pipe guide slider 217. The heat-melt pipe 9 is placed on the first pad 224, and then the cutting cylinder 221 works to drive the cutter 222 and the first pressing block 225 to move downward. Under the elastic force of the spring 226, the first pressing block 225 first compresses the hot-melt pipe 9, and the cutting knife 222 moves downward The lower movement cuts off the hot-melt pipe 9; then, the finger cylinder 2121 is reset to loosen the hot-melt pipe 9, and the hot-melt pipe delivery cylinder 211 is reset to drive the finger cylinder 2121, the first clamping block 2122 and the second clamping block 2123 to return to their original positions , and then, the pushing cylinder 41 moves downward and passes through the pushing plate 43 to push the hot-melt pipe 9 in the two U-shaped grooves 31 onto the steel needle 8, and then, the pushing cylinder 521 works and pushes the needle mounting plate 526 Drive the push needle 51 to push the steel needle 8 and the hot-melt tube 9 into the heat-shrinkable tube 10 at the same time; while the pushing cylinder 41 moves downward, the shaping cylinder 731 drives the lower shaping seat 72 to move upward, and the pushing cylinder 41 moves upward. The upper shaping seat 71 that moves downward cooperates together to shape the protruding short section of heat-shrinkable tube 10 into a special inverted plow shape; push cylinder 521 to reset, push cylinder 41 to reset, cut cylinder 221 to reset, and shift cylinder 64 resets, and the shaping cylinder 731 resets.

The optical fiber fusion splicing heat-shrinkable protective sleeve assembly device of the present invention adopts a steel needle feeding device to separate a steel needle to the bottom of the U-shaped groove, and a heat-melt pipe conveying and cutting device delivers a fixed-length heat-melt pipe to the U-shaped groove Cutting and cutting, the pushing device pushes the hot-melt tube onto the steel needle, and the assembly device pushes the steel needle and the hot-melt tube into the heat-shrinkable tube at the same time; high productivity.

The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be assumed that the specific implementation of the present invention is limited to these descriptions. For those of ordinary skill in the technical field of the present invention, without departing from the concept of the present invention, some simple deduction or replacement can be made, which should be regarded as belonging to the protection scope of the present invention.
