Description

Technical Field

[0001] The invention relates to the technical field of chip mounting, in particular to a chip mounting positioning device. Background Art

[0002] When producing and processing semiconductor instruments, it is necessary to install chips with functions such as control inside the semiconductor instruments (on circuit boards). At this time, the traditional method generally uses a robotic arm to grab and adsorb the chip module, automatically moving the chip module to the corresponding position of the semiconductor instrument, thereby improving the efficiency of semiconductor instrument production and processing.

[0003] The existing Chinese patent application with publication number CN114300367A discloses a chip mounting device and a chip mounting method, including a processing table, a fixed component and a cleaning component; the fixed component includes a fixed block, a movable block and a connecting member, the fixed block is fixedly mounted on the upper surface of the processing table, the movable block is slidably connected to the processing table and is located above the processing table, and the connecting member is located above the processing table; the cleaning component includes a support column, a base, a cleaning brush and a guide member, the support column is fixedly mounted on the lower surface of the processing table, the base is fixedly mounted on the lower surface of the support column, the cleaning brush is connected to the base through a guide member, and the guide member is located above the base; the invention automatically completes the chip installation and positioning operations by performing picking and mounting operations through a robot.

[0004] However, the chip mounting structure has the following defects when used in practice:

[0005] 1. When the existing chip installation structure adsorbs and grabs the chip, the chips to be adsorbed and grabbed are divided into microchips, small chips, medium-sized chips and large chips according to their size. Microchips and small chips are generally adsorbed and fixed by pneumatic suction cups because of their small size. When grabbing medium-sized chips and large chips with larger sizes, they are generally adsorbed and fixed by mechanical clamping. At the same time, in order to ensure the efficiency of chip installation and positioning, it is necessary to use both mechanical and suction cup methods to grab and fix multiple groups of chips. However, when installing and positioning the grabbed microchips, small chips, medium-sized chips and large chips respectively, the structures set on the side and other chips are likely to affect the accuracy of the installation and positioning of the chip;

[0006] 2. When the existing chip mounting structure is installed and positioned on a semiconductor device (circuit board, etc.), the position and angle of the chip installation are different, and the gap between two adjacent chips is small. At this time, the traditional auxiliary equipment is difficult to meet the requirements of installation and positioning of different chips when grabbing, adsorbing and installing the chips, which easily leads to problems such as chip installation misalignment and leakage.

[0044] Compared with the prior art, one or more of the above technical solutions have the following beneficial effects:

[0045] 1. In the chip installation and positioning device, when installing the chip, the servo motor drives the output end rotating gear to rotate, which, on the one hand, drives the eccentric gear and pneumatic suction cup connected by the side meshing to rotate forward, and on the other hand, drives the transmission belt and motor fixture connected by the synchronous wheel on the outer side of the coaxial end to rotate in the opposite direction, and adjusts the spacing between the pneumatic suction cup and the chips (of different sizes and types) adsorbed and fixed at the bottom of the motor fixture, so that when the chips adsorbed by the motor fixture and the bottom of the pneumatic suction cup are respectively installed and positioned, there is enough space for installing two adjacent chips, ensuring the accuracy of chip installation and positioning. At the same time, in this process, the chip that is not installed and positioned and the corresponding adsorption and fixing structure (motor fixture or pneumatic suction cup) are kept away from the semiconductor equipment (circuit board, etc.) where the chip is installed, so that the semiconductor equipment (circuit board, etc.) will not be damaged during the installation and positioning process, ensuring the quality of the chip after installation;

[0046] 2. In the chip installation and positioning device, when the chip is installed and positioned, the DC motor drives the output end drive gear to rotate to drive the coupling support to rotate, and then adjust the angle and direction of the chip fixed by the pneumatic suction cup or motor clamp at the bottom of the coupling support, so as to achieve the installation and positioning operation of the chip at different angles. At the same time, the rotating coupling support is also provided with a main shaft inside, so as to ensure that when adjusting the chip installation position, the chip installation angle can be adjusted by driving the main shaft to rotate on the inside of the coupling support through the driving motor. At this time, the design of the coupling support, on the one hand, reduces the space occupied when adjusting the chip installation position and angle, and on the other hand, the two operations do not interfere with each other and are performed synchronously, so as to ensure the efficiency of chip installation and positioning;

[0047] 3. In the chip installation and positioning device, when installing and positioning the chip, the chip installation mechanism that adsorbs and grabs the chip moves the chip installation mechanism to the semiconductor instrument or the location where the chip is stored by driving the intermediate turntable and the rigid mechanical frame to rotate through the DC motor, and completes the adsorption, grabbing, transportation and installation and positioning operations of the chip. At the same time, when adsorbing, fixing and installing the chip, the deflection motor drives the output end change arm to rotate and the lifting cylinder drives the support turntable to rotate, so as to further adjust the specific position of the chip during installation, thereby realizing the chip installation and positioning operation intelligently;

[0048] 4. In the chip installation and positioning device, the larger chips (medium or large) are gripped and fixed by the motor clamp, and the smaller chips (micro or small) are adsorbed and fixed by the pneumatic suction cup, which meets the requirements of semiconductor instruments for the installation and positioning of chips of different types and sizes. At the same time, when mechanical grasping is used to install and position medium or large chips, the installation and positioning operation is more stable and will not fall off. When the suction cup is used to adsorb and fix micro or small chips, the installation and positioning operation is more accurate and will not block the chip installation and positioning process.
