The embodiment of the application provides a grabbing device and processing equipment for solve the unstable technical problem of suction nozzle absorption chip.
In the embodiment of the application, as shown in fig. 2, the gripping device includes a suction nozzle 1, a flow detection device 2, a first electromagnetic valve 3, a positive pressure air source 4 and a negative pressure air source 5, wherein the flow detection device 2 is communicated with the suction nozzle 1; the first electromagnetic valve 3 is communicated with the flow detection device 2; the positive pressure air source 4 is communicated with the first electromagnetic valve 3; the negative pressure air source 5 is communicated with the first electromagnetic valve 3. Namely, the negative pressure air source 5, the first electromagnetic valve 3, the flow detection device 2 and the suction nozzle 1 are communicated in sequence.
In the present embodiment, the negative pressure air source 5 is used for generating negative pressure so that the pressure in the air path is less than atmospheric pressure, so as to suck the chip through the suction nozzle 1; the positive pressure air source 4 is used for generating positive pressure so that the pressure in the air path is greater than atmospheric pressure, and the chip sucked on the suction nozzle 1 falls off from the suction nozzle 1. The negative pressure gas source 5 and the positive pressure gas source 4 may each include a vacuum pump to generate a negative pressure or a positive pressure by the vacuum pump.
When the chip is sucked, the negative pressure air source 5 works, and the first electromagnetic valve 3 is opened, so that the negative pressure air source 5 is communicated with the flow detection device 2; simultaneously positive pressurized air source 4 is out of work, perhaps positive pressurized air source 4 work is in order to produce the malleation, but the gas circuit of positive pressurized air source 4 is closed to first solenoid valve 3 to reduce the influence of the malleation that positive pressurized air source 4 produced to the negative pressure that negative pressurized air source 5 produced, so that produce the negative pressure in the suction nozzle 1, thereby absorb the chip. When the chip is placed, the positive pressure gas source 4 works, and the first electromagnetic valve 3 is opened, so that the positive pressure gas source 4 is communicated with the flow detection device 2; meanwhile, the negative pressure air source 5 does not work, or the negative pressure air source 5 works to generate negative pressure, but the first electromagnetic valve 3 closes the air path of the negative pressure air source 5 so as to reduce the influence of the negative pressure generated by the negative pressure air source 5 on the positive pressure generated by the positive pressure air source 4, so that the positive pressure is generated in the suction nozzle 1, the chip sucked on the suction nozzle 1 is jacked open by the positive pressure air flow, and the purpose of placing the chip is realized.
The negative pressure air source 5, the first electromagnetic valve 3, the flow detection device 2 and the suction nozzle 1 are sequentially communicated so as to generate negative pressure in the suction nozzle 1, and therefore a chip is sucked through the suction nozzle 1; the positive pressure air source 4 is communicated with the first electromagnetic valve 3 so as to generate positive pressure in the suction nozzle 1 through the positive pressure air source 4, so that a chip sucked on the suction nozzle 1 falls off; the air flow flowing through the flow detection device 2 is detected by the flow detection device 2, whether the negative pressure in the suction nozzle 1 is enough to completely adsorb the chip is judged, and the negative pressure air source 5 is controlled to provide enough negative pressure in the suction nozzle 1, so that the aim of stably adsorbing the chip is fulfilled, the stability of adsorbing the chip by the suction nozzle 1 is improved, and the situation that the chip is not adsorbed or falls off after being adsorbed due to the fact that the negative pressure in the suction nozzle 1 is not enough to completely adsorb the chip is avoided; because flow detection device 2 sets up between first solenoid valve 3 and suction nozzle 1, consequently can reduce because of devices such as first solenoid valve 3 leak gas and lead to the error of the flow of flow detection device 2 measuring to whether can judge suction nozzle 1 adsorb the chip completely more accurately according to the flow that flow detection device 2 detected and obtain, thereby realize that suction nozzle 1 adsorbs the purpose of chip steadily, improve the stability that suction nozzle 1 adsorbs the chip.

Wherein, this time of predetermineeing can be according to actual demand manual setting.
Specifically, when the average flow value detected by the flow detection device 2 is 157 to 167ml/min, it can be determined that the suction nozzle 1 does not suck the chip;
when the average flow value detected by the flow detection device 2 is 95-126 ml/min, it can be determined that the suction nozzle 1 sucks the chip, but an air leakage gap exists between the suction nozzle 1 and the chip, so that the chip is in risk of falling, that is, the suction nozzle 1 does not firmly suck the chip;
when the average flow value detected by the flow detection device 2 is 85-95 ml/min, the suction nozzle 1 can be judged to completely suck the chip, and the risk of falling does not exist basically.
It can be understood that when the average value of the flow detected by the flow detecting device 2 is large, it indicates that the negative pressure generated by the negative pressure air source 5 is small, and the chip cannot be completely adsorbed, so that the negative pressure can be increased by the negative pressure air source 5, so that the chip can be completely adsorbed by the suction nozzle 1, and the stability of the chip being adsorbed by the suction nozzle 1 is improved.
