Description

Loader track pad device

Technical field

The utility model relates to a kind of loader track pad device.

Background technology

Need use pad device in the track of product design loading devices such as semiconductor packages such as BGA, QFN, LQFP; Cushion block is positioned at selects two positions in glue position and load position, when framework (Leadframe) or substrate (substrate) feeding device from loader is transported on the track, again via stepping index connecting gear; Transmit in orbit and stepping framework or substrate; When being sent to when selecting glue position and load position, the cushion block that is positioned at correspondence position has then played the effect of carrying support frame and substrate, simultaneously through being derived from the vacuum bottom the cushion block; Latch frame or substrate prevent that it from displacement occurring, getting loose in selecting glue and load process.

With reference to figure 1; The track pad device structure of the traditional structure that traditional semiconductor packaging device carries is comparatively simple; Only comprise an overall structure; Be positioned at cushion block 5 surperficial middle parts and have several vacuum holes 6, vacuum suction-operated makes to fit between framework or substrate and the cushion block and reaches the purpose of latch frame or substrate.But in the actual product operation process; There are the difference of product design (length, width, cellular construction quantity etc.) in its framework of Different products or board structure itself; Use same cushion block to cooperate different framework or substrate, a lot of vacuum holes are in blank state, can't effectively rely on the vacuum suction effect that framework or substrate and heat block surface are fitted tightly; Cause between itself and cushion block and the space occurs; Then leak vacuum, do not reach the purpose of latch frame or substrate, and then have influence on the gluing process quality and the load positional precision of product.

The utility model content

In view of the problems referred to above that exist in the prior art, the main purpose of the utility model is to address the deficiencies of the prior art, thereby a kind of loader track pad device that can effectively adsorb framework or substrate raising product point glue quality and load positional precision is provided.

For realizing above-mentioned purpose; The utility model provides a kind of loader track pad device; Comprise the cushion block base, the cushion block base is fixedly installed in the track point glue position and the load position of loader, and cushion block base top is provided with inverse-T-shaped groove; Cushion block base bottom is provided with vacuum hole; Loader track pad device also comprises " T " shape replace block, and " T " shape replace block is installed in the inverse-T-shaped groove on the cushion block base, and " T " shape replace block is provided with a plurality of vacuum holes that are connected with vacuum hole or vacuum tank.

Preferably, a plurality of vacuum tanks on " T " shape replace block are " X " shape.

Preferably, four jiaos of the cushion block base are symmetrically arranged with screw hole, are used for the cushion block base is fixedly installed in the track point glue position and the load position of loader.

Preferably, inverse-T-shaped groove is to offer along at least one side of cushion block base, so that " T " shape replace block pushes in the inverse-T-shaped groove along at least one side of cushion block base or from inverse-T-shaped groove, extracts.

Compared with prior art, the utlity model has in following advantage and the beneficial effect one or several:

1. the loader track pad device of the utility model; This device adopts interchangeable " T " shape replace block; Vacuum hole on " T " shape replace block or vacuum tank are connected with the vacuum hole of cushion block base bottom; Can change corresponding " T " shape replace block according to the specifications and models of framework or substrate, improve the applying degree of the vacuum suction of product on loader equipment track cushion block, effectively promote gluing process quality and load positional precision.

2. the loader track pad device of the utility model adopts removable " T " shape replace block, and it is fastening to need not screw, replaces convenient and swift.
