Description

Technical Field

[0001] The utility model relates to the technical field of clamping equipment, in particular to a clamping equipment for integrated circuit welding. Background Art

[0002] An integrated circuit is a miniature electronic device or component. It uses a certain process to interconnect the transistors, resistors, capacitors, inductors and other components and wiring required in a circuit. It is made on a small piece or several small pieces of semiconductor wafers or dielectric substrates, and then packaged in a tube shell to become a miniature structure with the required circuit function. The integrated circuit needs to be welded during processing, and the integrated circuit board must be clamped and fixed for welding.

[0003] When some existing integrated circuit clamping devices clamp the circuit board for welding, one side of the circuit board is against the desktop. When the staff needs to weld the other side of the circuit board, they need to take down the circuit board, turn it over, and then use the clamping device to re-fix it. Turning over the circuit board is relatively cumbersome, which is inconvenient for the staff to perform welding work, greatly reducing the welding efficiency and low practicality. In view of this, we propose a clamping device for integrated circuit welding to solve the above problems. Utility Model Content

First, the staff fixes the circuit board through the clamping assembly. When the staff needs to flip the circuit board, the first motor 24 is started, and the rotation of the output shaft of the first motor 24 drives the rotation of the first worm 11. Because the card slot 14 and the card block 15 are slidably connected, the rotation of the left first worm 11 can drive the rotation of the sliding rod 13, and the rotation of the sliding rod 13 drives the rotation of the right first worm 11. The rotation of the two first worms 11 respectively drives the rotation of the two first worm wheels 16, and the rotation of the two first worm wheels 16 The rotation drives the rotation of the two second worm gears 17 respectively, and the rotation of the two second worm gears 17 drives the rotation of the two second worm wheels 6 respectively.

The outer surfaces of the two fixing rods 8 are slidably sleeved with clamping plates 9. Both sides of the clamping plates 9 are inclined surfaces. A spring 10 is fixedly connected between the clamping plates 9 and the inner wall of the first guide groove 7. The spring 10 is sleeved on the outer surface of the fixing rod 8. The staff inserts the circuit board from the inclined surfaces on both sides of the clamping plates 9. At this time, because the circuit board itself has thickness, the two clamping plates 9 will slide inside the first guide groove 7. At this time, the spring 10 will shrink. Subsequently, the two clamping plates 9 rely on the elastic force of the spring 10 itself to fix the circuit board.

When the staff rotates the bidirectional threaded rod 19, the rotation of the bidirectional threaded rod 19 will drive the two guide blocks 20 to slide inside the second guide groove 18, and the movement of the two guide blocks 20 will drive the displacement of the two fixed plates 4, so as to finally adjust the distance between the two fixed plates 4.

A driving gear 22 is fixedly connected to the output shaft of the second motor 21, and a driven gear 23 is fixedly connected to the lower surface of the rotating table 3. The driven gear 23 is also rotatably connected to the interior of the first rotating groove 2. The driving gear 22 and the driven gear 23 are meshed and connected. The second motor 21 is started by a staff member, and the driving gear 22 is driven to rotate by the rotation of the output shaft of the second motor 21, and the driven gear 23 is driven to rotate by the rotation of the driving gear 22.

Because the card slot 14 and the card block 15 are slidably connected, the rotation of the left first worm 11 can drive the rotation of the sliding rod 13, and the rotation of the sliding rod 13 drives the rotation of the right first worm 11. The rotation of the two first worm gears 11 drives the rotation of the two first worm wheels 16 respectively, and the rotation of the two first worm gears 16 drives the rotation of the two second worm gears 17 respectively. The rotation of the two second worm gears 17 drives the rotation of the two second worm gears 6 respectively. At this time, the rotation of the second worm gear 6 drives the rotation of the clamping assembly, and finally the flipping of the circuit board is realized.
