Description

Technical Field

[0001] The present invention relates to the technical field of lead frame processing, and specifically relates to a lead frame processing device with a rotary material receiving function. Background Art

[0002] As a chip carrier for integrated circuits, a lead frame is a key structural component that realizes the electrical connection between the internal circuit leads of a chip and the external leads by means of bonding materials (gold wire, aluminum wire, copper wire), forming an electrical loop. It plays a role as a bridge connecting to external wires. Most semiconductor integrated circuits require the use of lead frames, which are important basic materials in the electronic information industry.

[0003] During the production process of lead frames, stamping and cutting are required. Before the lead frames are received, they need to be transported to the cleaning equipment after stamping, and then the cleaning equipment cleans the lead frames, followed by drying with a dryer, and finally receiving the materials. Existing lead frame processing devices still have some deficiencies, such as:

[0004] 1. When cutting lead frames, waste chips are usually generated, and the waste chips are scattered in the external environment, which has a certain impact on the environment, and it is not convenient for workers to collect the waste chips;

[0005] 2. Existing drying devices usually only dry one side of the lead frame, and the drying effect is poor. When it is necessary to dry the other side, manual flipping is required, which is difficult to meet the needs of workers;

[0006] 3. Existing material receiving devices, when they sense that the lead frame reaches the material receiving station, the clamping device will loosen, and the lead frame will fall down under its own gravity. In this way, due to the relatively high station, directly falling will cause damage to the lead frame. Summary of the Invention

[0059] The six-axis suction cup 5 transfers the cut lead frame to the cleaning tank 401. The lead frame lands on the filter plate 414. The output end of the second cylinder 403 drives the cover plate 404 to move downward to cover the top of the cleaning tank 401, and cleaning is carried out in the cleaning tank 401. Secondly, the output end of the ejecting motor 413 drives the ejecting screw rod 411 to rotate, so that the filter plate 414 moves upward. Finally, the output end of the feeding motor 409 drives the feeding screw rod 406 to rotate, so that the feeding plate 408 moves to push the lead frame onto the guide plate 415, and it slides down to the drying station 6 through the guide plate 415.

[0060] Further, in this embodiment, please refer to Figure 6 As shown, a guide plate 415 is fixedly installed on the back of the cleaning tank 401.

[0061] The working principle and usage process of this device: When using the present invention, the six-axis suction cup 5 sucks the lead frame to be processed on the feeding station 2 and places it on the upper end of the cutting table 310. The output end of the servo motor 311 drives the threaded rod 312 to rotate, so that the first movable member 314 and the second movable member 315 approach each other, driving the two L-shaped plates 316 to approach each other. The inner sides of the vertical plates of the two L-shaped plates 316 clamp the lead frame. Secondly, the electric lifting rod 318 drives the pressing plate 317 to move downward, thereby clamping and fixing the lead frame. The electric telescopic rod 304 drives the cutting table 310 into the interior of the cutting box 301. Secondly, the output end of the transverse motor 322 drives the transverse screw rod 320 to rotate, so that the movable frame 323 moves horizontally back and forth, thereby driving the cutting knife 328 to move horizontally back and forth. Also, the output end of the longitudinal motor on the outer side of the movable frame 323 drives the longitudinal screw rod 324 to rotate, so that the movable plate 326 moves vertically back and forth, thereby driving the cutting knife 328 to move vertically back and forth. Then, the output end of the first cylinder 327 drives the cutting knife 328 to move downward, realizing that the cutting knife 328 can move in the horizontal, vertical, and longitudinal directions to cut the middle part of the lead frame. After cutting, finally, the output end of the flipping motor 309 drives the cutting table 310 to flip, so that the waste chips generated by cutting fall into the drawer 329 for collection.

[0062] The six-axis suction cup 5 transfers the cut lead frame to the cleaning tank 401. The lead frame lands on the filter plate 414. The output end of the second cylinder 403 drives the cover plate 404 to move downward to cover the top of the cleaning tank 401, and cleaning is carried out in the cleaning tank 401. Secondly, the output end of the ejecting motor 413 drives the ejecting lead screw 411 to rotate, causing the filter plate 414 to move upward. Finally, the output end of the feeding motor 409 drives the feeding lead screw 406 to rotate, causing the feeding plate 408 to move and push the lead frame onto the guiding plate 415, and the lead frame slides down through the guiding plate 415 to the drying station 6. The lead frame is flipped by the flipping plate 606, so that the two drying lamps 607 respectively dry the front and back sides of the lead frame, and the drying effect is good, meeting the needs of the staff. Finally, when the lead frame reaches the receiving station 7, one of the vacuum plates 703 sucks the lead frame and rotates 120 degrees. Then the vacuum plate 703 releases the adsorption of the lead frame, and the lead frame slides down, changing the way that the lead frame directly falls under its own gravity, avoiding the situation of damage to the lead frame and meeting the needs of the staff.

[0063] The foregoing shows and describes the basic principles, main features and advantages of the present invention.
