In addition, horizontal wheel, vertical wheel, drive wheel lateral wall circumference all are equipped with a plurality of hemisphere archs, and the hole cooperation on hemisphere arch and the semi-manufactured goods splicing tape 1 avoids semi-manufactured goods splicing tape 1 to take place the skew.

As shown in fig. 2-3, a wire end closing mechanism 3 is installed at one side of the horizontal section of the semi-finished product adhesive tape 1, the wire end closing mechanism 3 comprises a base 5, and the base 5 is slidably arranged on a slide rail seat 6 and is driven by a first telescopic cylinder 7 to move back and forth; the locating slot 8 is installed to base 5 top front end, and pneumatic clamping jaw 9 is installed to the rear end, and pneumatic clamping jaw 9 carries out the centre gripping closure to the wire rod end, makes things convenient for the later stage like this to the chip centre gripping.

When the wire 1.4 of the semi-finished product adhesive tape 1 is aligned with the positioning groove 8, the first telescopic cylinder 7 extends out, and the base 5 is close to the wire 1.4. After the wire rod 1.4 is in place, the wire rod passes through the positioning groove 8, and the end head of the wire rod 1.4 is opposite to the clamping plate of the pneumatic clamping jaw 9. Because the front half section of the wire 1.4 is peeled after being sheared at the front station, the left wire harness and the right wire harness in the wire 1.4 which is doubled have intervals, and the ends of the two wire harnesses of the wire 1.4 can be squeezed and closed by the closing action of the pneumatic clamping jaw 9.

The pressing block assembly 22 has three groups, and one group of inverted U-shaped rubber blocks is used for extruding the two groups of adhesive tapes 1.3, so that the adhesive tapes 1.3 can be firmly fixed again. The group of pressing blocks are positioned on one side of the wire end closing mechanism 3 and can be used for pressing the front half section of the wire 1.4 before closing to keep the wire in a straight state; and the other group of pressing blocks are positioned at the other side of the wire end closing mechanism 3 and can be used for pressing the front half section of the closed wire 1.4 to ensure that the wire is kept in a straight state again to prepare for subsequent sandwich sheets. When the wire 1.4 of the semi-finished product adhesive tape 1 is opposite to the supporting plate at the pressing mechanism 18, the lifting cylinder 19 contracts, and the pressing block assembly 22 moves downwards to finish the corresponding extrusion action. Then the lifting cylinder 19 is extended and reset.

As shown in fig. 4-5, the chip feeding mechanism 4 includes a sliding bottom plate 10, and the sliding bottom plate 10 is driven by a second telescopic cylinder 11 to move back and forth.

Connecting plates 26 are fixed on the left and right sides of the mounting base 12, walking wheels 25 are mounted at the ends of the connecting plates 26, the outer sides of the walking wheels 25 are in contact with a positioning plate 24, and the positioning plate 24 is driven to move left and right through a pushing cylinder 23. When the pushing cylinder 23 at one end extends out, the pushing cylinder 23 at the other end contracts, the walking wheels 25 are always attached to the positioning plate 24, and the mounting base 12 moves left and right under the action of the pushing cylinder 23.

A right clamping plate 14 is fixed on the mounting seat 12, and the front end of the right clamping plate 14 is a tip, so that the wires 1.4 can conveniently pass through two wire bundles. The right clamping plate 14 is opposite to the left clamping plate 13, the left clamping plate 13 is fixed on the sliding block 15, and the sliding block 15 slides left and right along the slide way of the mounting seat 12. A left-right moving air cylinder 16 is fixed at the rear end of the mounting base 12, and the left-right moving air cylinder 16 drives the sliding block 15 to move. When the chip is required to be clamped, the left-right moving air cylinder 16 contracts, the left clamping plate 13 is closed to the right clamping plate 14, and the chip is clamped.

A pallet 27 is fixed to the slide base plate 10, the pallet 27 is positioned at the lower ends of the left and

right clamp plates

13, 14, and the upper end surface of the pallet 27 is in contact with the lower end surfaces of the left and

right clamp plates

13, 14. The pallet 27 facilitates later placement of the chip. The supporting plate 27 is provided with a slot 28 at a position corresponding to the left clamping plate 13 and the right clamping plate 14. The slot 28 prevents the support plate 27 from colliding with the wire 1.4 when the chip is clamped to the wire 1.4.

The working principle and the process are as follows:

1) when the semi-finished product bonding belt 1 horizontally passes through the wire end closing mechanism 3, the lifting cylinder 19 contracts, the pressing block assembly 22 presses downwards, the wire harness of the wire 1.4 can be pressed to be straight, and then the wire harness reaches the positioning groove 8. At this time, the first telescopic cylinder 7 extends out, so that the end of the wire 1.4 passes through the positioning groove 8 and is opposite to the clamping plate of the pneumatic clamping jaw 9. And the pneumatic clamping jaw 9 acts to clamp the wire harness end of the wire 1.4, so that the wire harness end of the wire 1.4 is bent and deformed and is closed. The pneumatic gripper 9 is then released and the first telescopic cylinder 7 is retracted. While continuing the forward movement, the pressure piece assembly 22 located on the right side of the wire end closing mechanism 3 is pressed flat again by the pressure piece assembly 22, and then the conveying is continued.

2) And when the semi-finished product adhesive tape 1 vertically passes through the chip feeding mechanism 4, taking the position of the graph 1 as an initial state. At this time, the second telescopic cylinder 11 is contracted, so that the slide base plate 10 is moved toward the semi-finished adhesive tape 1, and the movement locus is shown as (r) in fig. 10. In place, the strand end of the wire 1.4 enters the slot 28. At this time, the left and

right clamp plates

13 and 14 hold the chip and are positioned at the left side of the wire rod 1.4, and the lower end face of the chip is in contact with the upper end face of the pallet 27.

3) Then the left pushing mechanism 17 pushes the mounting base 12 to move rightwards, and the motion track is shown as the second in fig. 10. Since the front end of the right clip 14 is pointed, the right clip 14 passes through the space between the upper and lower strands of the wire 1.4 and enters between the upper and lower strands of the wire 1.4. After the chip is positioned between the upper and lower strands of the wire 1.4 after continuously moving to the right, the left clamping plate 13 and the right clamping plate 14 loosen the chip, and the upper and lower strands of the wire 1.4 can clamp the chip through bending force due to the bending deformation of the ends of the strands of the wire 1.4. After the semi-finished product adhesive tape 1 continues to move downwards for a short distance, the other pneumatic clamping jaw stretches out, the chip and the wire rod 1.4 are clamped again, and then the chip and the wire rod are loosened and retreated, so that the chip is prevented from falling in the subsequent conveying process, and the later-stage welding is guaranteed to be reliable.

4) And the second telescopic cylinder 11 extends out to enable the sliding bottom plate 10 to be far away from the semi-finished product bonding tape 1. The motion trail is shown in fig. 10.

5) Then the mounting seat 12 is pushed leftwards into position by the pushing mechanism 17 at the right side, and the motion track is shown as the fourth in fig. 10. The left and

right jaws

13, 14 are now positioned to the left of the slot 28. The manipulator clamps the chip and places the chip on the supporting plate 27 between the left clamping plate 13 and the right clamping plate 14, the left-right moving cylinder 16 contracts, and the left clamping plate 13 and the right clamping plate 14 approach and clamp the chip. The state is restored to the initial state.

6) And repeating the processes 2) to 5), and repeatedly feeding and clamping the chips in the process of intermittently and forwards conveying the semi-finished adhesive tape 1.
