Bonding fixture and mechanical arm

Abstract

The invention discloses a bonding fixture and a mechanical arm. The bonding fixture comprises a worktable. The worktable is movably connected to the upper portion of a body, a magnetic force mechanismis rotationally connected into a cavity formed at a joint of the body and the worktable, magnetic conduction sheets for conducting the magnetism of the magnetic force mechanism are mounted on the worktable, an adjusting screw for adjusting the horizontal rotation locations of the magnetic force mechanism and controlling the magnetic flux of the magnetic force mechanism is mounted in the body, a short-circuit sheet which is embedded in the body is mounted on a side of the magnetic force mechanism, and temperature adjusting heating pipes are arranged in the worktable. The bonding fixture and the mechanical arm have the advantages that a series of problems of easiness in slipping, poor fixing properties and easiness in damaging shells of products of existing bonding fixtures can be ingeniously solved by the aid of magnetic adsorption principles of the magnetic force mechanism; the magnitude of magnetic force can be adjusted, the magnetic force can be combined with the heating pipes, accordingly, the surface activity of metal can be enhanced during bonding, the bonding speeds can be increased, the bonding quality can be improved, and the work efficiency of the bonding fixture and themechanical arm can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of bonding process, in particular to a bonding fixture and a mechanical arm. Background technique [0002] At present, there are three working modes for bonding machine fixtures: the first one is to place the product on the fixture table by its own weight, which is prone to shaking and displacement during bonding, and the product is easy to slip off the table. The second is vacuum adsorption, which uses an external vacuum source to generate adsorption force to absorb the product. This method puts forward higher requirements on the stability of the vacuum and the flatness of the product, such as unstable vacuum, out-of-tolerance product flatness, and During bonding, the vacuum pipes are entwined and folded to lose vacuum, and the product cannot be fixed, which affects the bonding quality. The third is mechanical compression, which compresses the product by a mechanical device during work, which has an impact...

Problems solved by technology

[0002] At present, there are three working modes for bonding machine fixtures: the first one is to place the product on the fixture table by its own weight, which is prone to shaking and displacement during bonding, and the product is easy to slip off the table

The second is vacuum adsorption, which uses an external vacuum source to generate adsorption force to absorb the product. This method puts forward higher requirements on the stability of the vacuum and the flatness of the product, such as unstable vacuum, out-of-tolerance product flatness, and When bonding, the vacuum tubes are entwined and folded to lose vacuum, and the product cannot be fixed, which affects the bonding quality

Every time a product is replaced, the pressure plate needs to be released, which is very cumbersome, affects efficiency and damages the product

The fixing device is easily damaged, and the later maintenance cost is relatively high
