Description

Technical Field

[0001] The utility model belongs to the technical field of chip loading, in particular to a chip loading mechanism in a plastic tube. Background Art

[0002] In the chip feeding mechanism, there is a material distribution mechanism, which often uses a cylinder structure or a bottom rail vacuum to ensure that the chips in the track will not be blown away during the material distribution process. However, both structures are not very stable, and the phenomenon of chips being blown away still exists. In addition, the UPH (units per hour) of the mechanism using these two methods is affected. Correspondingly, due to the reduction of UPH, the length of the track is lengthened to increase the number of chips in the track. At the same time, the number of storage tubes in the silo is also small, which increases the frequency of material loading by on-site personnel. The current mechanisms are long and heavy, which makes installation and transportation inconvenient. Utility Model Content

The front material box 805 and the rear material box 806 are used to collect empty material tubes, and there is a height difference between them, so that the front end of the material tube will be higher than the rear end after entering the material box, so that the chip will not fall out when it is pushed into the material box when there are still chips in the tube, and the middle part of the front material box 805 and the rear material box 806 is empty, which is convenient for the operator to take the material tube from the middle.

[0077] Working principle of a chip feeding mechanism in a plastic tube:

[0078] Put the material tube with chips into the front and rear bins, the front end of the material tube is between the front bin adjustment piece 404 and the front bin side plate 405, the rear end is between the rear bin adjustment piece 725 and the rear bin side plate 726, the corresponding bottom surface of the material tube is in contact with the tube push bottom plate 64, and the middle section of the material tube is between the tube blocking and pushing unit 63 and the tube blocking piece 65. At this time, the tube blocking cylinder 62 is pushed out to the left, the material tube reaches the discharge position, the tube pressing cylinder 503 extends to press the front end of the material tube, the front push cylinder 711 retracts, and drives the front push tube block 714 to move forward, thereby pushing the material tube forward, so that the front end of the material tube fits with the 203 track entrance. The front push cylinder 711 extends to make the front push tube block 714 move backward. The downward pressure cylinder 715 and the lower clamping cylinder 732 extend simultaneously, clamping the material tube between the upper clamping block 717 and the supporting foam 734, and the tail blowing air in the upper clamping block 717 is turned on to blow the chips in the material tube into the track between the track bottom rail 203 and the track cover plate 204. In this process, the knocking cylinder 505 drives the knocking block 506 to knock the material tube, so that the chips in the material tube can smoothly enter the track. The chip moves forward in the track through the bottom track air blowing provided by the ventilation bottom plate 202. At this time, the terminal body 335 fits the track, and the groove of the terminal body 335 can just accommodate a chip. After the optical fiber body 336 sees the chip, the chip is adsorbed in the groove of the terminal body 335, and the motor 321 drives the terminal body 335 to move forward to the material picking position. When the corresponding motor 321 drives the terminal body 335 to move forward, the eccentric shaft 3213 moves forward synchronously, and the pressing head 349 is moved downward through the pressing mechanism 34 to press the chip at the front end of the track to ensure that the chip in the track will not be blown away when the terminal body 335 moves forward. After the chip is taken away at the material taking position, the optical fiber body 336 cannot see the chip, so the motor 321 drives the end body 335 back to the initial position and fits with the track. At the same time, the pressure head 349 also returns to the initial position above the upper surface of the chip in the track. At this time, the chip is blown into the groove of the end body 335, and this process is repeated to complete each material separation action.

[0079] The downward pressure cylinder 715 and the lower tube clamping cylinder 732 are extended at the same time to clamp the material tube between the upper tube clamping block 717 and the supporting foam 734. After the tail blowing air in the upper tube clamping block 717 is turned on, the tube pushing cylinder 632 retracts, driving the tube blocking block 636 to flip over. At this time, the tube blocking block 636 is located as a whole below the bottom surface of the material tube, and the tube blocking cylinder 62 can move rightward back to the position of the material bin. After it is in place, the tube pushing cylinder 632 is extended, driving the tube blocking block 636 to flip over, and clamping the next material tube to be made between the tube blocking block 636 and the tube blocking sheet 65.

[0080] After the emitting optical fiber 208 and the tube pressing optical fiber 513 do not see the chips within the specified time, it is considered that all the chips in the material tube have entered the track. At this time, the tube pressing optical fiber 513 is lifted, the lower clamping cylinder 732 and the lower pressing cylinder 715 are retracted, and the material tube is in a free state. Then the tube blocking cylinder 62 drives the material tube to move left to the material discharge position. During the movement of the tube blocking cylinder 62, the tube blocking block 636 will contact the previous finished material tube and push it to move left, so that it enters the material box of the front material box 805 and the rear material box 806. Repeat the action of the material tube reaching the material discharge position.
