In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

To achieve the above objective, an embodiment of the present invention provides a chip pickup device. As shown in FIG. 1 to FIG. 3, a chip pickup device includes:

Conveyor belt 1, pick-up part, second exhaust fan 2, drive part and control part, wherein,

The conveyor belt 1 has a mesh structure, and the chips are transferred on the conveyor belt 1;

The pick-up part includes a suction cup 21 , a first suction fan 22 and an electric cylinder 23 , the suction cup 21 is arranged above the conveyor belt 1 , and the first suction fan 22 is connected to the suction cup 21 through a suction pipe 24 . connected, the electric cylinder 23 is powered with the suction cup 21 to drive the suction cup 21 to move up and down;

The driving part is powered with the electric cylinder 23 for driving the electric cylinder 23 to move back and forth in the horizontal direction;

The second exhaust fan 2 is arranged below the conveyor belt 1;

The control part is electrically connected with the second exhaust fan 2, and is used to control the second exhaust fan 2 to stop working when the suction cup 21 is in contact with the chips on the conveyor belt 1, and when the chips leave the After the conveyor belt 1 is on, the second exhaust fan 2 starts to work.

When the device is used to pick up the chip, the driving part controls the electric cylinder 23 to move, and moves the suction cup 21 to the top of the chip. At this time, both the first exhaust fan 22 and the second exhaust fan 2 start to work, and the suction force of the first exhaust fan 22 is smaller than that of the first exhaust fan 22. The suction force of the second exhaust fan 2, the chip is still on the conveyor belt 1 at this time, when the pollution particles on the chip will be sucked away by the first exhaust fan 22, the electric cylinder 23 is controlled to extend, and when the suction cup 21 is in contact with the chip, the control The part controls the second exhaust fan 2 to stop working. At this time, the chip loses the downward suction force. Under the operation of the first exhaust fan 22, the chip is sucked up by the suction cup 21. At this time, the controller controls the second exhaust fan 2 to start to work. The chip is sucked up, and the distance between the chip and the second exhaust fan 2 increases. At this time, the suction force of the second exhaust fan 2 on the chip is reduced, the chip will not fall on the suction cup 21, and finally the electric cylinder 23 is driven by the driving part. Move to transfer the chip.

It can be seen from the above that the device can remove the contaminating particles on the chip through the operation of the first exhaust fan 22 before the chip is sucked, which ensures that there is no contaminating particle on the chip before the chip is sucked, and avoids the pollution particle causing the subsequent processing of the chip. Influence, improve the chip yield rate.

In some embodiments, the control part includes a pressure sensor 31, a spring 32 and a controller. One end of the spring 32 is fixedly connected to the suction cup 21, and the other end is fixedly connected to the pressure sensor 31.

Before the suction cup 21 comes into contact with the chip, the pressure sensor 31 will first contact the conveyor belt 1. After the contact, the pressure sensor 31 obtains a signal, and transmits the signal to the controller. The controller controls the second exhaust fan 2 to stop working. After the suction cup 21 leaves the conveyor belt 1, the pressure sensor 31 will leave the conveyor belt 1 after the chip. When the pressure sensor 31 leaves the conveyor belt 1, the controller receives the signal sent by the pressure sensor 31 and controls the second motor 44 to restart. Start, and so on.
