Practice proves that the lower pressure degree of the suction nozzle is controlled by the air cylinder, the precision can reach +/-10%, and the requirement of the chip industry can be well met.
The grating ruler 402 is arranged on the side wall of the connecting block 208, the reading head 403 faces the grating ruler 402, and the upper end of the reading head is connected with the outer wall of the air cylinder 401. When the cylinder 401 drives the connecting block 208 to ascend and descend, the reading head 403 can read parameters on the grating ruler 402 and feed the parameters back to the precise air pressure control system, so that the precise air pressure control system can precisely control the expansion amplitude of the piston rod 405, and further the precise control of the ascending and descending of the suction nozzle 201 is realized.
In addition, the grating scale 402 and the reading head 403 can also quickly confirm the initial position of the suction nozzle 201 after the suction nozzle 201 or the air guide rod 202 is replaced, so that the debugging time is reduced, and the operation efficiency is improved.
The above is the overall structure of the present invention, and the specific operation mode is as follows: when picking up a chip, the motor 301 drives the suction nozzle 201 to rotate, so that the suction slot at the bottom of the suction nozzle 201 is aligned with the chip; then, the air compressor inflates towards the air cylinder 401 through the air pipe joint 404, a piston rod 405 in the air cylinder 401 is driven to move downwards, the connecting block 208 and the air guide rod 202 are driven to descend, the suction nozzle 201 at the bottom of the air guide rod 202 descends to a position close to the chip but not in contact with the chip, and the descending amplitude of the suction nozzle 201 is controlled through the reading head 403 and the grating ruler 402; then, an air valve connected with the suction nozzle 209 sucks air, negative pressure is formed at a suction groove at the bottom of the suction nozzle 201, and chip picking is realized. Then the air compressor is inflated to change the air, and the connecting block 208 and the air guide rod 202 rise to the original position under the resilience of the spring 206.
During chip mounting, the motor 301 drives the chip to rotate, so that the chip is aligned with a bonding pad of the circuit board, the air compressor inflates the air cylinder 401, the air cylinder 401 drives the connecting block 208 and the air guide rod 202 to descend, the suction nozzle 201 attached with the chip is attached to the circuit board, and the downward pressure of the suction nozzle 201 is achieved by controlling the air pressure in the air cylinder through the precision air pressure control system. Then, the air valve connected with the suction nozzle 209 discharges air, and the chip leaves the suction nozzle 201; finally, the air compressor inflates the air cylinder 401 to change air, and the connecting block 208 and the air guide rod 202 rebound and reset under the action of the spring 206. A complete set of pick-and-place actions is thus completed.
