[0002] Bonding wire refers to a structure with good electrical and thermal conductivity that is required to connect the semiconductor electronic chip in the integrated circuit with the external lead frame.

[0028] To sum up, in the utility model, when it is necessary to reel up the bonding wire, conventional machinery is used to move the bonding wire and enter the shell body 1 through the wire entry port 103. Since the bonding wire itself has a certain strength, the lower pressure plate 401 is pressed down after moving to the lower pressure plate 401 of the clamping unit 4. After the lower pressure plate 401 moves down, it drives the tooth plate 402 to move down, thereby driving the lower pressure gear 403 to rotate, thereby driving the clamping gear 404 to rotate, thereby driving the matching gear 405 to rotate, thereby causing the swing rod 406 to rotate and drive the connecting plate 408 to rotate, thereby driving the clamping plates 409 on both sides to clamp the bonding wire, and then the clamping plates 409 are translated and clamped by the action of the sliding block, and the sliding block slides by the spring slide plate 412. When the bonding wire is clamped, the translation unit 2 is started.

[0029] In the utility model, the translation motor 201 in the translation unit 2 is started and drives the translation screw 202 and the translation gear 204 to rotate, wherein the translation gear 204 drives the bottom winding gear 301 to rotate, thereby rotating the reel 302, thereby driving the clamping unit 4 to rotate and wind the bonding wire. In order to prevent the bonding wire from being wound too thick, the protective shell 101, the partition plate 304 and the fixed plate 303 are used to limit the position, and the bonding wire is evenly wound on the reel 302 through the translation unit 2.

[0030] The spool 203 is rotated by the guide wheel 210, and the guide wheel 211 is rotated by the guide wheel 212. The guide wheel 212 is rotated by the guide wheel 213, and the guide wheel 214 is rotated by the guide wheel 215. The guide wheel 216 is rotated by the guide wheel 217, and the guide wheel 218 is rotated by the guide wheel 219. The two wire-entry clamping wheels 210 clamp the bonding wire and assist in moving the bonding wire, and the translation spring 205 and the translation plate 206 are used to control the clamping force. When the winding is completed, the translation servo 207 stops operating, and the bonding wire can be cut off on the outside. If you want to extract the internal bonding wire, you can use the translation servo 207 and the translation motor 201 to start, rotate in the opposite direction, and then drive the bonding wire to move outward, so that the wire-entry clamping wheels 210 and the reel 302 rotate in the opposite direction. When the bonding wire is extracted, the bonding wire no longer presses down on the lower pressure plate 401, and the lower pressure plate 401 loses pressure. The clamping plate 409 uses the spring slide plate 412 to drive the sliding block 411 to slide and then release the bonding wire, thereby completing the extraction of the bonding wire.
