The working principle of the assembly equipment and the universal jig 10 thereof is as follows:

according to the contour and size of the workpiece 12, a corresponding number of jig units 200 are selected, and since the adsorption block 220 and the carrier 100 are attracted to each other by magnetic force, the jig units 200 can be picked up and fixed to appropriate positions, so that the jig units 200 can reasonably support the workpiece 12.

When the workpiece 12 is supported, compressed air is introduced into the external negative pressure mechanism, the compressed air flows in the vent hole 216, and in the process that the compressed air flows in the vent hole 216, because the gas passes at a high speed, the surrounding pressure of the gas passing at a high speed is rapidly reduced, the air in the connecting hole 214 and the adsorption hole 218 is taken away, so that the pressure in the adsorption hole 218 is reduced, and further, a pressure difference is formed between the pressure and the external atmospheric pressure, and the workpiece 12 is adsorbed and fixed under the negative pressure.

According to the assembling equipment and the jig thereof, as the jig unit 200 and the carrying platform 100 are mutually attracted through magnetic force, when the size of the workpiece 12 changes, the position of the jig unit 200 can be adjusted to adapt to the size of the workpiece 12, the universal jig 10 can be universal, different jigs are not required to be designed according to different sizes, the production cost can be saved, and the production cost is improved.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
