Electronic carrier tape burr removal machine

Abstract

This invention relates to an electronic carrier tape burr removal machine, comprising a feeding shaft, a receiving shaft, a conveying track, and a plasma jetting device. The feeding shaft and the receiving shaft are spaced apart, and the receiving shaft can be driven to rotate, transporting the carrier tape from the feeding shaft to the receiving shaft. The conveying track is located between the feeding shaft and the receiving shaft, allowing the carrier tape to move linearly along the conveying track during transport towards the receiving shaft. The plasma jetting device is located on one side of the conveying track and can jet a plasma beam onto the carrier tape as it moves along the conveying track. The kinetic energy is transferred to the burrs through plasma impact, causing the burrs to peel off and pulverize, thereby removing the burrs in the detection hole. When transporting electronic components via carrier tape, the detection results through the detection hole are more accurate, avoiding transport errors.

Claims

1. An electronic carrier tape burr removal machine for treating a plurality of detection holes of a carrier tape, comprising: at least one feed shaft; at least one take-up shaft spaced apart from the feed shaft and rotatable by a drive to convey the carrier tape from the feed shaft toward the take-up shaft; a conveying track disposed between the feed shaft and the take-up shaft, allowing the carrier tape to move linearly along the conveying track during its conveying toward the take-up shaft; and a plasma jetting device disposed on one side of the conveying track, capable of jetting a plasma beam toward the carrier tape as it moves along the conveying track to remove burrs from the detection holes.

2. The electronic carrier tape burr removal machine as claimed in claim 1, wherein the conveying track comprises two parallel track bars, each track bar having at least one recessed notch extending along the length of the track bar for embedding the carrier tape.

3. The electronic carrier tape burr removal machine as claimed in claim 2, wherein the two tracks are movable relative to each other in a width direction perpendicular to the length direction, such that the notches of the two tracks are brought closer or further apart.

4. The electronic carrier tape burr removal machine as claimed in claim 1, wherein the conveyor track is connected to at least one water guide block, the at least one water guide block having at least one coolant channel through which coolant can flow through the water guide block to exchange heat with the conveyor track.

5. The electronic carrier tape burr removal machine as claimed in claim 1, comprising a moving device to which the plasma jetting device is connected, and which is driven by the moving device to move along a jetting direction perpendicular to the length direction of the conveyor track, thereby approaching or moving away from the carrier tape.

6. The electronic carrier tape burr removal machine as claimed in claim 1, comprising a protective cover, the protective cover and the plasma jetting device being arranged along a jetting direction perpendicular to the length direction of the transport track, and respectively located on opposite sides of the transport track.

7. The electronic carrier tape burr removal machine as described in claim 1, comprising a detection device located on one side of the conveyor track, capable of acquiring an image of the carrier tape after the carrier tape is sprayed with a plasma beam by the plasma jetting device.

8. The electronic carrier tape burr removal machine as claimed in claim 1, comprising a dust removal device disposed between the conveyor track and the take-up shaft, and including a dust removal box that allows the carrier tape to enter when it is conveyed from the conveyor track toward the take-up shaft, and the interior of the dust removal box is connected to a blower.

9. The electronic carrier tape burr removal machine as claimed in claim 1, comprising a dust removal device disposed between the conveyor track and the take-up shaft, and comprising two rotatable brush wheels tangentially arranged so that when the carrier tape is conveyed from the conveyor track toward the take-up shaft, it passes between the two brush wheels and is scraped by the two brush wheels.

10. The electronic carrier tape burr removal machine as described in claim 8 or 9, wherein the dust removal device includes at least one ionizing air bar capable of blowing ionizing air toward the carrier tape.

11. The electronic carrier tape burr removal machine as claimed in claim 1, comprising two drive wheels positioned corresponding to the conveyor track, capable of clamping the carrier tape from both sides as the carrier tape moves along the conveyor track, and at least one of the drive wheels being driven to rotate, thereby moving the carrier tape toward the take-up shaft.

12. The electronic carrier tape burr removal machine as described in claim 1, wherein a drive device is provided for each of the feed shaft and the take-up shaft, the drive device comprising a motor assembly and a linear driver, the motor assembly being connected to and capable of driving the corresponding feed shaft or take-up shaft to rotate, and being disposed on the linear driver so that the linear driver can drive the corresponding feed shaft or take-up shaft to move axially.
