Detailed Description

The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1 to 3, a chip pulling mechanism for separating a chip 101 and a braid 102 of a chip braid 100 includes: the device comprises a rack 1, a horizontal transverse rail 11, a push plate 4, a pushing driving device 3, a lifting plate 6, a sheet pulling driving device 7, a sheet pulling air claw 8 and a limiting block 9.

The machine frame 1 has a vertically arranged work surface 1.1. The position of the working surface 1.1 is the wafer pulling station. After the chip braid 100 arrives there, the chip pulling operation is started.

The horizontal rails 11 are provided with a pair, one end of each horizontal rail extends to the working surface 1.1, and the horizontal rails 11 are used for bearing the chip braids 100 so that the chip braids can horizontally move on the upper edge.

The push plate 4 is movably arranged on the machine frame 1 along the direction vertical to the working surface 1.1. After the chip braid 100 is placed on the horizontal cross rail 11, the pushing plate 4 can work to push the chip braid 100 to the chip pulling station. Note that, after the chip braid 100 is placed on the horizontal slide rail 11, the chip 101 is disposed downward, and the pusher 4 pushes the chip 101 to push the braid 100 forward when moving. The pushing driving device 3 is a cylinder, a push rod of the pushing driving device is connected with the push plate 4, and the push plate 4 is driven to move towards the working face 1.1 by means of driving force. The pushing driving device 3 further has a reset function, and can drive the pushing plate 4 to return to the initial position.

The lifting plate 6 is movably mounted on the frame 1 along the vertical direction, the sheet pulling driving device 7 is an air cylinder, and a push rod of the air cylinder is connected with the lifting plate 6, so that the lifting plate 6 is driven to lift above a sheet pulling station. The sheet pulling driving device 7 has a reset function and can drive the lifting plate 6 to return to an initial position.

The plurality of the piece pulling air claws 8 are arranged on the lifting plate 6 and correspond to a plurality of parts of the braid 102 on the chip braid 100, so that the pulling force is uniformly applied, and the synchronous separation of the braid 102 and the chip 101 is realized.

The limiting structures are arranged on the working face 1.1 in multiple groups, and each group of limiting structures comprises three limiting blocks 9. Three limiting blocks 9 in each group of limiting structures are distributed in an arc shape so as to be matched with the outline structure of the chip 101. The gap between two adjacent limit blocks 9 is used for accommodating the pins of the chip 101.

The mechanism also comprises a first guide rod 13, a first linear bearing 5, a second guide rod 14 and a second linear bearing 2.

The first guide rods 13 are arranged perpendicularly to the working surface 1.1, and the number of the first guide rods is two. The first linear bearing 5 is connected with a first guide rod 13 in a sliding mode and fixedly connected with the push plate 4. Two first guide rods 14 are vertically arranged, and the second linear bearing 2 is connected with the second guide rods 14 in a sliding mode and fixedly connected with the lifting plate 6.

After the chip braid 100 is placed on the horizontal cross rail 13, the pushing driving device 3 is started to drive the push plate 4 to move towards the direction of the chip pulling station, and the chip braid 100 is contacted in the moving process and pushed to the contact working surface 1.1. The push plate 4 is then repositioned. At the moment, the piece pulling driving device 7 is started to drive the lifting plate 6 to descend to a set height, the piece pulling air claw 8 is started to clamp the braid 102 of the chip braid 100, then the piece pulling driving device 7 reversely drives the lifting plate 6 to rise, and at the moment, due to the action of the limiting block 9, the chip 101 cannot rise along with the braid 102 and is separated from the braid 102 under the action of tension.

It should be noted that, the air cylinder in the present invention may also be replaced by a component capable of realizing linear driving, such as a hydraulic cylinder or an electric push rod, and the control module and the control program required for controlling the component to operate according to a predetermined program or procedure are prior art, and do not belong to the improvement of the present invention, and therefore are not described in detail.
