Description

Technical Field

[0001] This utility model relates to the field of chip packaging technology, specifically a chip packaging positioning device. Background Technology

[0002] Chip packaging typically requires a precision robotic arm with a clamping device for automated operation, placing the chips onto a dedicated chip tray.

[0003] However, when using a robotic arm to assist in chip packaging, the tray needs to be placed in a designated position before the robotic arm can package the chips. If the tray is placed manually, it is easy for the tray to shift, causing the robotic arm to place the chips with deviation, which affects the chip packaging process. To address this issue, we propose a chip packaging positioning device. Utility Model Content

[0026] The working principle is as follows: First, the base 21 is installed on the chip placement point of the robotic arm. The two second stops 24 are equidistant from the center of the base 21, and the two first stops 22 are also equidistant from the center of the base 21. Therefore, with the cooperation of the two first stops 22 and the two second stops 24, the position of the chip tray 1 is restricted, and the center of the chip tray 1 is aligned with the center of the base 21. At this time, the chip tray 1 will be aligned with the chip placement point of the robotic arm, so that the robotic arm can place the chip on the chip tray 1 for packaging. When encountering chip trays 1 of different sizes, the first stops 22 are fixed with T-shaped blocks 27 that are slidably connected to the base 21, and the second stops 24 are fixed with sliding rods 25 and limiting blocks 26 that are slidably connected to the base 21. The two ends of the upper connecting rod 31 are connected to the auxiliary shaft integrally formed on the upper turntable 32 through the node structure 33. The first stop 22 and the upper turntable 32 are rotatably connected respectively. The two ends of the lower connecting rod 34 are also rotatably connected to the slide rod 25 and the lower turntable 35 through the node structure 33 and the auxiliary shaft integrally formed on the lower turntable 35. The lower turntable 35 and the upper turntable 32 are rotatably connected to the fixed shaft 36 fixed at the center point of the base 21 through the rotating shaft 37. Therefore, after the upper turntable 32 and the lower turntable 35 rotate, the second stop 24 or the first stop 22 can be pulled to slide synchronously towards the center of the base 21 to meet the locking requirements of chip trays 1 of different sizes. Then, the screw 310 is screwed into the first nut 38 inside the upper turntable 32, the second nut 39 inside the fixed shaft 36, and the first nut 38 inside the lower connecting rod 34 to restrict the rotation of the upper turntable 32 and the lower connecting rod 34 and lock the position of the first stop 22 and the second stop 24.
