[0001] This utility model relates to the field of chip testing technology, specifically to a positioning and rotating mechanism for an integrated circuit testing tape and reel machine. Background Technology

[0002] Integrated circuit test tape and reel machine is a core piece of equipment in the post-packaging process of semiconductor packaging. It is mainly used to tape and package integrated circuit chips that have passed the test.

[0003] When testing chip tape and reel, the chip needs to be fixed. When mechanical clips are used for fixing, it is difficult to control the clip force. If it is too tight, it can easily scratch the chip package shell or pins. If it is too loose, it will not be fixed firmly, which will directly lead to a decrease in processing and testing accuracy, an increase in defect rate, and affect the authenticity and consistency of test results.

[0004] Now, a positioning and rotating mechanism for an integrated circuit test tape and reel machine is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a positioning and rotating mechanism for an integrated circuit testing tape and reel machine, so as to solve the problem of difficulty in controlling the buckling force mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning and rotating mechanism for an integrated circuit testing tape and reel machine, comprising a base, with fixed columns fixedly connected to the four corners of the top of the base, and a placement platform fixedly connected to the top of the four sets of fixed columns, and an adjustable position fixing mechanism provided on the outer side of the placement platform. The adjustable position fixing mechanism includes four sets of sliding rods, which are fixedly connected to the outside of the placement platform. A movable block is provided on the upper side between the four sets of fixed columns. Four sets of movable rods are movably connected to the outside of the movable blocks. Four sets of limiting blocks are movably connected to the top of the four sets of movable rods. Four sets of sliding grooves are opened inside the four sets of limiting blocks. A fixed plate is fixedly connected to the rear end of the two sets of fixed columns on the rear side. A stepper motor is fixedly connected to the rear end of the fixed plate. A movable shaft is movably connected to the front end of the fixed plate. An elliptical rotating block is sleeved on the outside of the movable shaft.

[0007] As a further technical solution of this utility model, the output end of the stepper motor is connected to the movable shaft, the size of the movable shaft is matched with the elliptical rotating block, and the elliptical rotating block rotates at a vertical angle.

[0008] As a further technical solution of this utility model, the dimensions of the four sets of sliding grooves are matched with the sliding rods, the four sets of limiting blocks move horizontally on the outside of the sliding rods, and the four sets of limiting blocks are closely attached to the chip.

[0009] As a further technical solution of this utility model, the four sets of movable rods are arranged symmetrically, and the movable block moves up and down.

[0010] As a further technical solution of this utility model, a fixed seat is provided at the bottom of the base, a servo motor is fixedly connected to the top of the fixed seat, and a mounting plate is fixedly connected to the top of the fixed seat.

[0011] As a further technical solution of this utility model, the output end of the servo motor is connected to the base, and the base rotates at a horizontal angle.

[0012] As a further technical solution of this utility model, the interior of the elliptical rotating block is provided with an installation hole, the front end of the movable shaft is provided with a threaded hole, and the front end of the threaded hole is threadedly connected to a threaded rod.

[0013] As a further technical solution of this utility model, the size of the threaded hole matches the threaded rod, and the size of the mounting hole matches the movable shaft.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the positioning and rotating mechanism of the integrated circuit test tape machine not only realizes the accurate and rapid positioning of the chip to be tested, but also realizes the horizontal rotation of the chip to be tested, and also realizes the fixing of chips of different sizes to be tested. The device is equipped with a slide bar, limit block, slide groove, movable block, movable rod, fixed plate, stepper motor, movable shaft, and elliptical rotating block. In use, the chip to be tested is placed on the placement table, and the stepper motor is started by the PLC controller inside the device. The stepper motor rotates at a specific angle and speed according to a specific program. The movable shaft drives the elliptical rotating block to rotate vertically. The top of the elliptical rotating block is in contact with the movable block. The movable block is movably connected to the corresponding limit block by the movable rod. The four sets of limit blocks move horizontally on the outside of the slide bar. When the movable block moves downward, the limit block is tightly in contact with the chip to be tested, thereby achieving accurate and rapid positioning of the chip to be tested. Equipped with a fixed base, servo motor, and mounting plate, the servo motor is started by the PLC controller inside the device during use. The output of the servo motor is connected to the base, which drives the chip to be tested to rotate horizontally. By rotating the chip, the angle and direction of the workpiece can be precisely adjusted, so that the workpiece fits perfectly with the equipment in the subsequent process. This solves the limitation of the fixed clamping mechanism that "the posture is not adjustable", and also avoids secondary clamping of the workpiece when it is transferred between workstations, reducing repeated positioning errors. It is especially suitable for scenarios with high precision requirements, such as integrated circuit test tape and reel machines. With mounting holes, threaded holes, and threaded rods, the elliptical rotating block can be disassembled and replaced by opening a threaded hole at the front end of the movable shaft. The outer dimensions of the movable shaft match the elliptical rotating block. The operator inserts the corresponding elliptical rotating block into the outer side of the movable shaft and then rotates the threaded rod at the front, thereby satisfying the need to fix chips of different sizes to be tested and processed.

[0019] A fixed base 13 is provided at the bottom of the base 1. A servo motor 14 is fixedly connected to the top of the fixed base 13.

Next, the servo motor 14 is started by the internal PLC controller. The output end of the servo motor 14 is connected to the base 1, and the base 1 drives... The chip to be tested rotates horizontally. By rotating the chip, the angle of the workpiece can be precisely adjusted, so that the workpiece fits perfectly with the equipment of the subsequent process. This solves the limitation of the fixed clamping mechanism that "cannot be adjusted in posture".
