Description

Technical Field

[0001] This utility model relates to the field of integrated circuit technology, and in particular to a positioning device for processing the shape of an integrated circuit (IC) substrate. Background Art

[0002] In the processing of integrated circuit (IC) substrates, precise positioning is crucial for ensuring processing accuracy and product quality. Traditional positioning devices often have several shortcomings. For example, they are not precise enough, making it difficult to quickly adapt to IC substrates of different sizes and shapes, leading to deviations during processing and affecting product yield. Moreover, traditional devices lack precise control over clamping force, often damaging the IC substrate due to excessive force or causing displacement due to insufficient force, which also hinders processing. Furthermore, some positioning devices are complex in structure and bulky, facing numerous difficulties in integration into existing IC substrate processing equipment, resulting in poor compatibility and limiting their widespread application in actual production.

[0003] Therefore, there is an urgent need for a positioning device for processing integrated circuit (IC) substrates that can achieve rapid and accurate positioning, precise control of clamping force, compact structure, and good compatibility to meet the growing production demands.

A bidirectional lead screw 21 is rotatably installed on the inner wall of the circular box 1. The output shaft of the motor 22 is axially fixedly connected to the bidirectional lead screw 21. Two sliders 2 are threadedly connected to the bidirectional lead screw 21, allowing adjustment of the distance between the two sliders 2, thereby adjusting the distance between the corresponding two clamping blocks. A geared disc 31 is rotatably installed inside the circular box 1. A bidirectional lead screw 32 is rotatably installed on the inner wall of the geared disc 31, threadedly connected to the two sliders 3. The bidirectional lead screw 32 is located below the bidirectional lead screw 21, allowing control of the distance between the two sliders 3 when the bidirectional lead screw 32 rotates, and also allowing the geared disc 31 to rotate. Two sliders 3 are controlled to deflect based on the placement seat 13. A motor 311 is fixedly installed on the circular box 1. The output shaft of the motor 311 extends into the circular box 1 and is fixedly fitted with a drive gear 312.

Both bevel gears 52 mesh with bevel gears 51 and can control the rotation of bidirectional lead screw 32 when bidirectional lead screw 21 rotates.

[0032] In order to ensure the accuracy of the adjustment and avoid instability after the adjustment is completed, both motor 22 and motor 311 are servo motors.

[0033] In this embodiment, in order to ensure that slider 12 can slide stably along the slot 11, and to ensure that the two sliders 23 can slide stably, and to achieve the effect of shielding and protecting motor 122 and motor 2311, the same guide rod 111 is fixedly installed on the inner walls of both sides of the slot 11.

[0034] In this embodiment, in order to provide shielding protection for the arc-shaped opening 12 without affecting the normal adjustment of the slider 2 3, an elastic cloth 121 is fixedly installed on the inner wall of the arc-shaped opening 12, and the elastic cloth 121 is fixedly connected to the corresponding slider 2 3.

[0035] The circuits, electronic components, and modules involved all employ existing technologies, which can be fully implemented by those skilled in the art, and need no further explanation. The content protected by this application does not involve improvements to the software, cables, or methods.

[0036] Working principle: In use, first turn on the power and place the integrated circuit (IC) carrier board on the placement seat 13. The rotation of motor 2 311 drives the bidirectional lead screw 2 32 to deflect to the required angle based on the placement seat 13 through the drive gear 312 and the gear plate 31. Then, by controlling the rotation of motor 1 22, the bidirectional lead screw 21 can be driven to rotate, thereby adjusting the distance between the two sliders 1 2 to accommodate IC carrier boards of different sizes. At the same time, with the cooperation of bevel gear 1 51, bevel gear 2 52 and rotating shaft 5, the rotation of bidirectional lead screw 2 32 can be controlled synchronously, thereby adjusting the distance between the two sliders 2 3. This allows the four clamping plates 43 to clamp and position the integrated circuit (IC) carrier board, ensuring its stability and accuracy during processing. The pressure sensor 44 can monitor the clamping force of the clamping plates 43 on the IC carrier board in real time, ensuring appropriate force and avoiding damage to the IC carrier board.
