Description

Technical Field

[0001] The present invention relates to the technical field of chip processing, and in particular to a chip picking device. Background Art

[0002] During the chip production and processing, in order to ensure that the chip can be moved to the designated processing position, it is necessary to use a picking device to pick up the chip.

[0003] After searching, the patent document with announcement number CN216120253U discloses a chip picker and a chip picking device. The picking device is provided with an adsorption end fixing part for installing a detachable adsorption end, so that the adsorption end can be conveniently replaced according to usage needs, and the installation sealing effect and installation stability of the adsorption end can be improved; in addition, the chip picker provided by this application can also include an adjustment component, through which the adsorption state of the chip picker can be conveniently adjusted, and the gas channel between the first end and the second end can be blocked when the chip picker is not in use, thereby reducing unnecessary power waste.

[0004] However, the above devices have certain defects when used:

[0005] When the above-mentioned picking device picks up the chip, it only uses gas adsorption components such as the adsorption end to adsorb and pick up the chip. When the required adsorption chip specifications are large, there is no supporting component under the chip, which can easily cause the chip to deviate from the adsorption end due to external contact during the transfer process. In severe cases, the chip can easily fall off from the adsorption end, resulting in the chip being unable to be stably adsorbed and picked up, reducing the picking stability.

It solves the problem that when the chip is only adsorbed and picked up by gas adsorption components such as the adsorption end, when the required adsorption chip specifications are large, there is no supporting component under the chip, which makes it easy for the chip to deviate from the adsorption end due to external contact during the transfer process.

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, other embodiments obtained by ordinary technicians in this field without making any creative efforts are all within the scope of protection of the present invention.

[0031] See also Figure 1-5 A chip picking device includes an electric push rod 1, a connecting tube 2 is fixedly provided at the end of the output shaft of the electric push rod 1, an adsorption syringe 3 is provided inside the connecting tube 2, and a suction cup 4 is connected to the air inlet end of the adsorption syringe 3. An elastic guide mechanism for limiting the position of the adsorption syringe 3 is provided between the adsorption syringe 3 and the inner wall of the connecting tube 2, and the elastic guide mechanism includes two symmetrically arranged sliders 14, the two sliders 14 are respectively fixed on both sides of the outer wall of the adsorption syringe 3, and a first slide groove is opened on both sides of the inner wall of the connecting tube 2. The slider 14 is slidably arranged in the first slide groove, and a support spring 15 is fixed between the slider 14 and the inner wall of the first slide groove;

[0032] A return spring 5 is provided on the wall sleeve of the piston rod of the adsorption syringe 3. The two ends of the return spring 5 are fixedly connected to the syringe barrel and the piston core rod of the adsorption syringe 3 respectively. An adsorption pickup mechanism is provided between the connecting tube 2 and the adsorption syringe 3. The adsorption pickup mechanism includes a connecting plate 11. The connecting plate 11 is fixedly connected to the lower end of the back side of the inner wall of the connecting tube 2. A connecting rope 12 is fixedly provided on the connecting plate 11 and the top of the piston core rod of the adsorption syringe 3. A guide plate 13 is fixedly provided on the upper side of the inner wall of the connecting tube 2. The transmission of the connecting rope 12 is arranged inside the guide plate 13. The top of the guide plate 13 is provided with a guide groove for cooperating with the transmission of the connecting rope 12.

[0033] An electromagnetic ring 23 is fixedly provided on the upper side of the inner wall of the connecting tube 2, and the electromagnetic ring 23 is sleeved on the outside of the connecting rope 12. A connecting magnet 17 is fixedly embedded on the upper end of the piston core rod of the adsorption syringe 3, and the electromagnetic ring 23 is magnetically matched with the connecting magnet 17.

[0034] When picking up the chip, the device is moved to the top of the chip and the suction cup 4 is brought into contact with the chip. Then the electric push rod 1 is started to move the connecting tube 2 downward. The connection between the slider 14 and the support spring 15 can press the adsorption syringe 3 and make the connecting tube 3 continue to move downward. During the downward movement of the connecting tube 3, the connecting plate 11 presses the connecting rope 12. At this time, the connecting rope 12 pulls up the piston core rod of the adsorption syringe 3 under the support of the guide plate 13, so that the adsorption syringe 3 can suck the air between the suction cup 4 and the chip. The chip can be stably adsorbed, and at the same time, the electromagnetic ring 23 is energized, so that the connecting magnet 17 is connected to the electromagnetic ring 23, and the position of the adsorption syringe 3 is determined to ensure stable adsorption of the chip. Then the device can be moved to move the chip to the specified position, and the electromagnetic ring 23 is de-energized to separate the connecting magnet 17 from the electromagnetic ring 23. Subsequently, under the elastic recovery of the return spring 5 and the support spring 15, the air inside the adsorption syringe 3 enters between the suction cup 4, so that the suction cup 4 cannot adsorb the chip and the chip is separated.

[0035] In order to stably support the bottom of the chip after it is adsorbed, Figure 1 and Figure 3 As shown, a horizontal plate 6 is fixedly sleeved on the lower end of the outer wall of the adsorption syringe 3, and two symmetrically arranged strip holes are provided at both ends of the inner part of the horizontal plate 6. A rotating tube 7 is provided in each of the multiple strip holes, and two symmetrically arranged support rods 8 are fixed on the outer wall of the rotating tube 7. The support rods 8 rotate with the inner wall of the strip hole, and an elongation limiting mechanism is provided inside the rotating tube 7. The elongation limiting mechanism includes a sleeve rod 16, which is slidably arranged in the rotating tube 7. A push spring 18 is provided between the sleeve rod 16 and the inner wall of the rotating tube 7. The rod walls of the multiple support rods 8 are sleeved with a torsion spring 19, and the two ends of the torsion spring 19 are fixedly connected to the rotating tube 7 and the inner wall of the strip hole respectively.

[0036] After the chip is adsorbed, the sleeve rod 16 squeezes the push spring 18 and enters the inside of the rotating tube 7. At this time, under the support of the support rod 8, the rotating switch 7 can drive the sleeve 16 to rotate, and after the chip adsorption is completed, the elastic force of the push spring 18 is restored to make the rod wall of the sleeve rod 16 contact the side wall of the chip, and under the rebound of multiple sleeves 16, the bottom of the chip can be stably supported.

[0037] In order to be able to push the multiple rotating tubes 7 after the chip is adsorbed, the sleeve rod 16 can slide out obliquely to support the bottom of the chip, such as Figure 1 and Figure 4-5As shown, support tubes 9 are fixed on both sides of the outer wall of the connecting tube 2, and a push plate 10 is slidably inserted into the support tube 9. The ends of the push plate 10 are cooperated with the two adjacent rotating tubes 7. A pushing and shifting mechanism for pushing the push plate 10 to move is provided between the piston core rod of the adsorption syringe 3 and the two push plates 10. The pushing and shifting mechanism includes a slide plate 20, which is fixedly sleeved on the outer side of the push plate 10. Second slide grooves are provided on both sides of the inner wall of the support tube 9. Both ends of the slide plate 20 are slidably provided in the two second slide grooves. A compression spring 21 is fixed between the inner walls of the slide plate 20 and the second slide grooves. Push blocks 22 are fixed on both sides of the upper end of the piston core rod of the adsorption syringe 3. The push block 22 contacts and cooperates with the end of the push plate 10, and an inclined surface is provided on the lower end of the push plate 10 close to the push block 22.

[0038] When the connecting tube 2 is continuously pressed, the upper end of the piston core rod of the adsorption syringe 3 moves upward, so that the push block 22 pushes the push plate 10, so that the push plate 10 moves laterally with the support of the slide plate 20 and the compression spring 21, and pushes the two rotating tubes 7 on the same side, so that the rotating tubes 7 rotate and tilt under the support of the support rod 8. At this time, after the position of the adsorption syringe 3 is fixed, the position of the push plate 10 is determined, which can ensure that the chip can always be supported by the sleeve rod 16 during picking and transferring, thereby ensuring the stability of the chip during picking and transferring.
