[0002] A chip, also known as an integrated circuit, microcircuit, microchip, or wafer, is a miniaturized circuit in electronics and is often manufactured on the surface of a semiconductor wafer. During chip production, the packaging process involves placing and soldering a copper sheet of a specific shape onto the corresponding chip. Only after a qualified soldered product is formed can it be encapsulated by injection molding.

[0003] In the production and processing of chip copper, the chip copper needs to be chemically mechanically polished in the latter part of the process. During the chemical mechanical polishing process, the chip copper is in a flat state, but after chemical mechanical polishing, subsequent processing is required, including cleaning (removing polishing residues) and annealing (improving the crystal structure of copper and reducing resistance). During cleaning and annealing, the chip copper needs to be placed vertically. The above production and processing requires the chip copper to be transferred from a flat state to a vertical state. In response to the above needs, the present invention proposes a chip copper production and processing device. Summary of the Invention

[0010] A further improvement is that the swinging suction cup frame group includes a longitudinal tube frame, and the left side of the longitudinal tube frame is welded with a plurality of transverse tube frames for rotating through a swinging channel formed at the left end between two adjacent roller conveyor frames, and a plurality of suction cups are arranged at intervals on the top surface of each transverse tube frame, and an air inlet hole is opened in the middle of the longitudinal tube frame, and an air suction hose for communicating with a vacuum pump is connected to the air inlet hole.

[0019] The roller conveyor belt 1 includes a base frame 11, and a plurality of roller conveyor frames 12 are longitudinally spaced apart on the top surface of the base frame 11, and each roller conveyor frame 12 is transmission-connected to a plurality of rollers 13, and a swing channel is formed at the left end between two adjacent roller conveyor frames 12. An infrared sensor 14 is provided on the left side of one of the roller conveyor frames 12 for positioning the chip copper a1 when it is conveyed to the left.

[0020] Each of the moving grooves 232 includes an arcuate moving groove 2321 , and a fixed opening 2322 is provided on the front side of the left groove wall of the arcuate moving groove 2321 , and a plurality of arcuate pressing slideways 2323 are provided on the disc 231 on the front and rear sides of the arcuate moving groove 2321 .

The two supporting and pressing wheel groups 2413 are composed of a pressing seat 2414 and a plurality of universal bearings 2415.

[0022] The suction cup swing frame group 244 includes a swing bracket 2441, and a swing suction cup frame group 2442 is hinged on the swing bracket 2441, and one side of the swing suction cup frame group 2442 is transmission-connected to a second servo rotator 2443 for swinging the swing suction cup frame group 2442 backward and back by 5-25°.

[0023] The swinging suction cup frame group 2442 includes a longitudinal tube frame 24421, and the longitudinal tube frame 24421 is welded with a plurality of transverse tube frames 24422 at intervals on the left side thereof for rotating through a swinging channel formed at the left end between two adjacent roller conveyor frames 12, and a plurality of suction cups 24423 are arranged at intervals on the top surface of each transverse tube frame 24422. An air inlet hole 24424 is opened in the middle of the longitudinal tube frame 24421, and an air suction hose 24425 for communicating with the vacuum pump 25 is connected to the air inlet hole 24424.

[0024] The vertical material clamping and conveying device 3 includes an annular chain conveyor frame 31, and a plurality of drag blocks 32 are connected to the annular chain conveyor frame 31 at intervals, and a pneumatic gripper 33 is vertically provided on the bottom surface of each drag block 32. The middle part of the lower end of the pneumatic gripper 33 is provided with an anti-stuck channel 34 for rotating through when the chip copper a1 is changed to a vertical guide by the guide mechanism 24.

[0025] When one of the said material-changing guide mechanisms 24 changes the guide of the chip copper a1 to rotate vertically counterclockwise through the middle of the said anti-jamming channel 34, the corresponding said angle compensation sliding group 241 rotates clockwise at an angle of 15-25° at the same frequency and speed as the counterclockwise rotation of the disc 231 for angle compensation, so that the chip copper a1 is intermittently paused and is vertically clamped by the pneumatic gripper 33.

[0026] Working principle: When the copper chip a1 processed by the chemical mechanical polisher is transported to the left by the roller 13 on the roller conveyor 1, it will be positioned after being sensed by the infrared sensor 14, and then the material-changing guide device 2 will perform the transfer operation, and the rotating drive end 22 will drive the rotating disk 23 to rotate counterclockwise at a constant speed. At this time, the various cross-tube racks 24422 on the material-changing guide mechanism 24 at the upper and lower ends of the rotating disk 23 will rotate in sequence and pass through a swing channel formed at the left end between the two adjacent roller conveyor racks 12, using the suction cup 24 423 sucks and rotates the chip copper a1 and lifts it, then extends longitudinally to the vertical clamping and conveying device 3 through the telescopic arm body 242 to the right side of a pneumatic gripper 33 of the vertical clamping and conveying device 3, and synchronously cooperates with the first servo rotator 245 and the direction-changing shaft 243 to make the suction cup swing frame group 244 change direction by 90 degrees. At this time, the chip copper a1 will rotate vertically counterclockwise. When the chip copper a1 rotates vertically counterclockwise from right to left and penetrates the middle of the anti-stuck channel 34, the chip Copper a1 is in a vertically aligned state. Since the rotating disk 23 rotates at a constant speed, the corresponding angle compensation sliding group 241 needs to be rotated clockwise at an angle of 19-21 degrees at the same frequency as the counterclockwise rotation of the disk 231 for angle compensation, so that the chip copper a1 can achieve intermittent pause and have enough static time to be vertically clamped by the pneumatic gripper 33. After the chip copper a1 is grasped by the pneumatic gripper 33, the second servo rotator 2443 needs to drive the swing suction cup frame group 2442 to swing backward at an angle of 10 degrees and cancel it synchronously. The suction cup 24423 absorbs the chip copper a1, which can increase the distance between the suction cup 24423 and the back side of the chip copper a1. This step can prevent the back side of the chip copper a1 from being scraped by the subsequent counterclockwise rotating suction cup 24423. When a material-changing guide mechanism 24 is rotated counterclockwise to the left end of the rotating disk 23, it needs to be initialized and reset so that when the material-changing guide mechanism 24 rotates back to the roller conveyor belt 1, the next chip copper a1 can be transported. The above-mentioned transport operation refers to the attached Figure 1 .

[0027] In addition, when the previous copper chip a1 is transported and adsorbed by a variable guide mechanism 24, the infrared sensor 14 will sense that there is no object, and the next copper chip a1 can be transported to the left through the roller 13.

[0028] In addition, after a pneumatic gripper 33 grabs the chip copper a1, the ring chain conveyor frame 31 transports the next pneumatic gripper 33 to the left through the transmission drag block 32 to the original position to wait for the transfer and transportation of the next chip copper a1, and the chip copper a1 vertically grabbed by the vertical clamping conveying device 3 will be transported in a ring to the cleaning equipment and annealing equipment on the rear side for processing. The above-mentioned chemical mechanical polishing, cleaning and annealing production operations are existing technologies and will not be elaborated on here.

[0029] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
