Abstract

A feeding device in manufacturing which is configured to feed a carrier tape includes a transmission mechanism and a buffering mechanism. The transmission mechanism is configured to receive the carrier tape and transfer the carrier tape to the buffering mechanism. The buffering mechanism includes a slide assembly, a feeder assembly, and an inductor. The slidable feeder assembly is mounted to the slide assembly, and is configured to receive the carrier tape transferred from the transmission mechanism. The slide assembly moves the feeder assembly. The inductor is mounted to one side of the slide assembly, and senses distances from the feeder assembly, to control a feeding speed of the transmission mechanism.

First claim

What is claimed is:

1. A feeding device configured to feed a carrier tape, comprising:
a transmission mechanism;
a buffering mechanism having
a slide assembly;
a feeder assembly slidably mounted to, and movable by, the slide assembly; and
an inductor mounted to the slide assembly;

wherein, the carrier tape is received by the transmission mechanism and fed into the feeder assembly;
wherein,
the inductor controls the speed of the transmission mechanism;
the feeding device further comprises a bracket and a fastening mechanism; and
the fastening mechanism and the buffering mechanism are arranged to either side of the bracket, and the transmission mechanism is arranged between the fastening mechanism and the buffering mechanism;
the bracket comprises a first column, a second column, a third column, a fourth column, and an electronic control box;
the fastening mechanism is mounted to the first column, the transmission mechanism is mounted to the second column, and the buffering mechanism is mounted to the third column; and
the electronic control box is electrically connected to the transmission mechanism and the buffering mechanism.

2. The feeding device as claimed in claim 1 , wherein:
the fastening mechanism comprises a roller, a slide assembly, a rope; a weight member, a slide block, and a pressing wheel; and
the fastening mechanism is configured to press the carrier tape and transfer the carrier tape to the transmission mechanism.

3. The feeding device as claimed in claim 2 , wherein:
the roller is mounted to one side of the first column;
the slide assembly is mounted to the first column under the roller;
the rope revolves the roller;
the weight member is connected to one end of the rope;
the slide block is mounted to the slide assembly, and is connected to the other end of the rope; and
the pressing wheel is mounted to the slide block.

4. The feeding device as claimed in claim 1 , wherein:
the transmission mechanism comprises a driver, a driving shaft, and a driving wheel;
the driver is mounted to the second column; and
one end of the driving shaft is connected to the driver, and the other end of the driving shaft passes through the driving wheel.

5. The feeding device as claimed in claim 4 , wherein:
the electronic control box slows the feeder assembly down to reduce a transferring speed of the carrier tape when the feeder assembly is moved away from the inductor; and
the electronic control box speeds the feeder assembly up to increase a transferring speed of the carrier tape when the feeder assembly is moved toward the inductor.

6. The feeding device as claimed in claim 4 , wherein the transmission mechanism further comprises a feeding wheel; and the feeding wheel is mounted under the driver to receive the carrier tape transferred by the driver.

7. The feeding device as claimed in claim 6 , wherein the feeding device further comprises a saving assembly, the saving assembly is mounted adjacent to the feeding wheel under the feeder assembly.

8. The feeding device as claimed in claim 7 , wherein the saving assembly comprises a plurality of saving wheels, the saving wheels are configured to receive the carrier tape from the feeding wheel and transfer the carrier tape to the feeder assembly.

9. The feeding device as claimed in claim 8 , wherein the slide assembly comprises a gear, a guide rail, a connecting rope, a weight member, and a slide block.

10. The feeding device as claimed in claim 9 , wherein:
the gear is mounted to one end of the third column;
the guide rail is mounted to the third column under the gear;
the connecting rope revolves the gear; and
the slide block is connected to one end of the connecting rope, and mounted to the guide rail.

11. The feeding device as claimed in claim 9 , wherein the feeder assembly is mounted above the saving assembly, and comprises a plurality of feeding wheels, the feeding wheels receives the carrier tape from the saving wheels.

12. The feeding device as claimed in claim 1 , wherein the feeding device further comprises a discharging mechanism, the discharging mechanism is mounted to the fourth column.
