Description

Technical Field

[0001] The invention relates to the technical field of chip tooling, in particular to a chip clamping tooling with guide rails and wire bonding. Background Art

[0002] Chip packaging is divided into manual and fully automatic packaging. Manual chip packaging, as the name implies, requires manual operation for chip bonding and wire bonding. Fully automatic chip packaging requires the use of fully automatic chip mounters and fully automatic wire bonding machines, which have high equipment costs, require programming and debugging for each chip, and also require manual loading and unloading. For microwave / RF products, many packaged products have very small orders of dozens or hundreds each time, and there are no particularly high requirements for the product chip bonding position and the arc length and arc height of the wire bonding. Manual assembly is more flexible and has high switching efficiency.

[0003] However, manual chip packaging, such as the wire bonding process, uses the heating table that comes with the manual bonding machine to fix the chip shell, which has big problems: 1. The hot table that comes with the bonding machine itself has a poor fixing effect on small shells. The chip shakes during the wire bonding process and part of the chip is suspended in the air, causing uneven heating of the chip shell and the chip shell to be skewed. The consistency of the solder joints during bonding deteriorates and the bonding reliability is also reduced to a certain extent.

[0004] In this case, there is an urgent need for a reliable and convenient chip shell clamping tool to clamp and fix the chip, and at the same time have heat conduction and convenient loading and unloading. At the same time, the tooling also needs to have a certain heat insulation function to avoid high temperature burns to the human body caused by the heat conduction part of the tooling during manual loading and unloading.

[0007] Chip clamping tool with guide rails, including:

[0008] A base, wherein a movable fastening plate is provided on the base, a fixed guide rail is provided on the base, and a movable guide rail is provided on the movable fastening plate;

[0010] A bottom moving shaft, the bottom moving shaft is arranged on the moving fastening plate and inserted into the moving groove in the base, and a rotating mechanism inserted into the bottom moving shaft is also arranged in the base;

[0011] When the rotating mechanism rotates, the movable fastening plate is driven to move along the fixed guide rail and the movable guide rail, so that the lower fixed platform is close to the upper fixed platform and the material placed on the base is clamped and fixed. When the rotating mechanism rotates in the opposite direction, the lower fixed platform is moved away from the upper fixed platform and the material placed on the base is released.

[0012] Preferably, a chip removal groove is provided on the movable fastening plate to prevent debris from getting stuck in the movable fastening plate.

[0014] Preferably, rotating the sleeve drives the spiral rod to rotate, so that the bottom movable shaft is gradually sleeved on the spiral rod, so that the lower fixed platform is close to the upper fixed platform, and rotating the sleeve in the opposite direction causes the bottom movable shaft to gradually move away from the spiral rod, so that the lower fixed platform is away from the upper fixed platform.

[0015] Preferably, an upper heat insulation frame is provided on the movable fastening plate, and a lower heat insulation frame is provided on the base, and the lower heat insulation frame also wraps the upper fixed plate, and the upper heat insulation frame and the lower heat insulation frame are used to prevent the user from being scalded.

When the upper fixed platform and the lower fixed platform clamp the material and press the retracted block into the silicone pad, the displacement rack drives the push rod to move, pushing the limit block to fit the frosting plate and against the trigger tube, so that the trigger tube clamps the locking plate, thereby locking the spiral rod, preventing the spiral rod from continuing to rotate, and allowing the spiral rod to rotate in the opposite direction, so that the lower fixed platform releases the material.
