Description

Technical Field

[0001] This utility model relates to the field of integrated circuit processing technology, specifically to an integrated circuit material gripping structure. Background Technology

[0002] An integrated circuit is a miniature electronic device or component. It is made by using certain processes to fabricate the transistors, resistors, capacitors, inductors, and other components required for a circuit, as well as the interconnection of wiring, on one or several small pieces of semiconductor wafers or dielectric substrates. Then, it is packaged in a package to become a miniature structure with the required circuit function. During the production process, integrated circuit materials need to be moved using special gripping tools.

[0003] However, existing gripping devices are prone to damaging integrated circuit boards because the grippers directly contact the boards. Furthermore, the metal grippers are susceptible to static electricity, which can cause short circuits and damage to the integrated circuit boards. Therefore, to protect integrated circuits from damage during gripping, some technologies have proposed gripping structures to assist in their movement. For example, a utility model patent with publication number CN221043384U proposes an integrated circuit gripping fixture. The two ends of the support rod have rotating shafts, which helps prevent the rotating shafts from detaching from the support rod during operation, thus preventing the grippers from malfunctioning. The upper end of the gripper is attached to the rotating shaft, which helps prevent the gripper from detaching from the rotating shaft when gripping the circuit board, thus preventing damage. A rubber protective sleeve is installed at the end of the gripper to increase the friction between the gripper and the circuit board and to prevent static electricity from causing short circuits and damage to the circuit board.

[0004] Based on the above-disclosed technical content, theoretically, the implementation of the relevant technical structure is beneficial for moving integrated circuit boards. However, according to the description in the above-disclosed technical content, because the distance between the claws at both ends of the gripper is the same, the gripper is specific to the size of the integrated circuit it is gripping. When the size of the integrated circuit is smaller than the distance between the claws, the integrated circuit will fall out of the gripper. When the size of the integrated circuit is larger than the distance between the claws, the gripper cannot grip the integrated circuit. At this time, the applicable range of the gripper is reduced, and the practicality of the gripper in actual use is reduced. Utility Model Content

[0030] Working Principle: In use, firstly, when multiple integrated circuits need to be gripped, adjust the positions of the main suction cup 1 and the auxiliary suction cup 2 according to the placement of the integrated circuits. Turn on the power of the first rotary motor 14. After the first rotary motor 14 is turned on, it drives the rotation of the spur gear 502 through the connection of the first rotating shaft 13. Due to the meshing connection between the spur gear 502 and the ruler strip 501, the circumferential rotation of the spur gear 502 drives the horizontal movement of the ruler strip 501. Simultaneously, the movement of the ruler strip 501 drives the extension rod 3 to extend and retract within the fixed rod 4. At the same time, the movement of the extension rod 3 drives the movement of the auxiliary suction cup 2 in the same direction through the connection of the outer casing 11. Once the auxiliary suction cup 2 is moved to the appropriate position, the power of the first rotary motor 14 can be turned off. Then, turn on the power of the vertical electric push rod 6. The extension and retraction of the output shaft inside the vertical electric push rod 6, through the connection of the disc 17 and the bent rod 18... The main suction cup 1 and the auxiliary suction cup 2 are driven to move vertically up and down until they are lowered to the surface of the integrated circuit. Then, the power supply of the vertical electric push rod 6 is turned off, and the power supply of the negative pressure pump 10 is turned on. Through the connection of the connecting pipe 9, the integrated circuit can be adsorbed onto the bottom of the main suction cup 1 and the auxiliary suction cup 2. Finally, the power supply of the vertical electric push rod 6 is turned on. The retraction of the output shaft inside the vertical electric push rod 6 drives the vertical movement of the integrated circuit. Then, the power supply of the second rotary motor 20 is turned on. The turning on of the second rotary motor 20 drives the rotation of the driven gear 802 through the connection of the second rotating shaft 25. Due to the meshing connection between the driven gear 802 and the driving gear 801, the circumferential rotation of the driven gear 802 drives the rotation of the driving gear 801. At the same time, the movement of the driving gear 801 drives the rotation of the main suction cup 1 and the auxiliary suction cup 2 through the connection of the column 7, thus realizing the rotational movement of the integrated circuit.
