As described in the background of the utility model, in the related art, in the process of assembling electronic devices such as mobile phones, in order to facilitate positioning and transferring of some workpieces (small parts in the electronic devices), a carrier with a positioning device is generally used. Because the electronic equipment such as a mobile phone and the like comprises a large number of workpieces, and for different types of workpieces, the requirements on the directions of clamping and positioning are different when the workpieces are clamped and positioned due to different structures, some workpieces can only be clamped and positioned along the Y direction, some workpieces can only be clamped and positioned along other certain directions of different Y directions, and the positioning device in the related art can only be clamped and positioned along one direction and cannot be compatible with the workpieces of different types.

In view of the above-mentioned problems, the embodiments of the present utility model provide a positioning device and a carrier, so as to solve the problem that in the related art, the positioning device can clamp and position workpieces in only one direction, which results in incompatibility of different types of workpieces.

In the process of placing the second row of workpieces, the first row of workpieces are adsorbed and fixed by vacuum, so that the risk of displacement is reduced.

Finally, the carrier is carried and moved to a third station again, and a third row of workpieces are placed. Specifically, before the third row of workpieces is placed, the vacuum adsorption function of the vacuum adsorption hole 13 is started, the step of placing the first row of workpieces is repeated, and the third row of workpieces are inserted into and clamped and positioned in the positioning space where the second pushing block and the third pushing block are located. In the process of placing the third row of workpieces, the first row of workpieces and the second row of workpieces are also adsorbed and fixed by vacuum, so that the risk of displacement is reduced.

The above is only one use mode of the carrier, and optionally, multiple rows of workpieces can be placed at a time and then fixed.

In addition, through the quick positioning device work piece of positioner and quick unlocking work piece, can shorten the dwell time of carrier, be favorable to accelerating the moving efficiency of carrier.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model.
