Referring to fig. 1 and 2, the chip clamp positioning and rotating pick-and-place mechanism for realizing full-automatic testing of the utility model is used for automatically picking and placing a clamp from a clamp carrier in chip testing, and comprises a support frame 12, wherein a spindle 7 is fixed at one end of the support frame 12, a stepping motor 13 is fixed at the other end of the support frame 12, the spindle 7 is connected with the stepping motor 13 through a transmission structure, and the stepping motor 13 drives the spindle 7 to rotate through the transmission structure.

The main shaft 7 comprises a fixed shaft 1, an installation space is arranged in the fixed shaft 1, a suction nozzle head 2 is arranged in the installation space, the lower end of the suction nozzle head 2 extends out of the lower portion of the fixed shaft 1, a compression spring 5 is arranged at the upper end of the suction nozzle head 2, the bottom of the compression spring 5 abuts against the top of the suction nozzle head 2, and a jacking screw 6 is arranged at the upper end of the compression spring 5 and can be used for adjusting the compression amount of the compression spring 5. The suction nozzle head 2 is provided with a strip-shaped limiting groove 21, and a limiting screw 3 is fixed in the strip-shaped limiting groove 21 and used for clamping the suction nozzle head 2 in an installation space to prevent the suction nozzle head from falling off, so that the suction nozzle head 2 plays a role in centering when in a lower limit position. The lower end of the suction nozzle head 2 is connected with an air pipe connector 4, and the air pipe connector 4 is connected with a vacuum air path. The main shaft 7 has the function of flexibly sucking products and can adjust the pressure of the suction nozzle head 2.

The chip clamp positioning and rotating pick-and-place mechanism for realizing the full-automatic test further comprises two bearings 8, and the two bearings 8 are installed and clamped on the main shaft 7 in pairs, so that the main shaft 7 is fixed in position and can rotate. The outer ring of the bearing 8 is clamped with a bearing sleeve 9, and the bearing sleeve 9 is used for keeping the position between the two bearings 8. And a locking nut 10 is fixed at the upper end of the main shaft 7 and used for fixing the relative position of the bearing 8 and the main shaft 7. An installation cavity is arranged in the support frame 12, a bearing end cover 11 is fixed at the upper end of the installation cavity, and the bearing 8 and the main shaft 7 are clamped in the installation cavity by the bearing end cover 11. The support frame 12 is provided with a mounting hole for assembling the positioning rotary taking and placing mechanism on the workbench.

Drive structure includes action wheel 14, follows driving wheel 15 and hold-in range 16, action wheel 14 is connected in step motor 13's output, connect in main shaft 7 from driving wheel 15, hold-in range 16 linkage action wheel 14 and follow driving wheel 15, step motor 13 provides drive power, does the precision positioning to main shaft 7 rotation angle through the subdivision of driver, and action wheel 14 transmits step motor 13 moment of torsion, and it is rotatory to drive main shaft 7 from driving wheel 15. A limiting block 17 is further fixed on the support frame 12, and the limiting block 17 is located on the side of the main shaft 7 to prevent the main shaft 7 from rotating too much.

The bottom of the suction nozzle head 2 is provided with micropores which are connected with a vacuum through an air pipe joint 4, and the size of the micropores is determined by the size of the chip. The vacuum pressure of the nozzle head 2 hardly changes in a distinguishable manner before and after the product is adsorbed, but changes in a weak airflow, so that the air pipe joint 4 needs an external flow meter as a means for detecting whether the product is adsorbed. The compression spring 5 is arranged between the inner part of the main shaft 7 and the suction nozzle head 2, so that the suction nozzle head 2 has enough stroke to play a role of buffering protection after the product is overpressurized. Similarly, when the product is placed, after the suction nozzle head 2 and the loading platform can generate overpressure properly, vacuum breaking and discharging are carried out after the product and the loading platform are ensured to be flat. The main shaft 7 is integrated with the functions of vertical guiding, adjustable pre-pressure and vacuum gas circuit, the modular integration provides convenience for use, and the positioning, rotating, taking and placing functions of the chip can be completed by controlling the rotating angle of the main shaft 7.

The main shaft 7 is installed in an installation cavity of the support frame 12, the bearing 8 is an angular contact ball bearing, and the position of the main shaft 7 is positioned through paired angular contact ball bearings. The lower end of the inner part of the mounting cavity is clamped below the bearing 8 and does not fall off, and the upper part of the mounting cavity is locked by a bearing end cover 11. One end of the main shaft 7 is provided with a shaft shoulder which is clamped on the inner ring of the bearing 8, and the other end of the main shaft 7 is provided with a locking nut 10 after passing through the paired bearings 8, so that the main shaft 7 is fixed on the support frame 12.

The driven wheel 15 at the tail part of the main shaft 7 is connected with the driving wheel 14 on the stepping motor 13 through a synchronous belt 16, the driven wheel 15 and the driving wheel 14 have different tooth numbers and play a role in reducing the speed after being connected. Therefore, the main shaft 7 can obtain higher torque and more accurate subdivision angle under the deceleration action. Because the rotation angle of the main shaft 7 can be influenced by an external air pipe, the main shaft 7 can be clamped by the limiting block 17 below the supporting frame 12 when the rotation angle is exceeded, and the air pipe is prevented from bypassing other structures.

Compared with the prior art, the chip clamp positioning and rotating pick-and-place mechanism for realizing full-automatic testing realizes the function of automatically picking and placing the clamp from the clamp carrying platform in chip testing, provides a solution for full automation of equipment, reduces manpower and greatly improves production efficiency; the pressure-adjustable flexible contact suction nozzle head 2 effectively protects the surface of a product and greatly improves the precision of the discharging place.
