The output ends of the two cylinders 631 have opposite movement directions, so that the four jigs 100 are conveniently arranged at four corners of the workbench 7. The first elastic piece 612 and the first elastic piece seat 613 are collectively referred to as a first elastic module, the second elastic piece 622 and the second elastic piece seat 623 are collectively referred to as a second elastic module, the first elastic module is located between the two jigs 100 in the same working area, the second elastic module is located between the two jigs 100 in the two working areas, the two air cylinders 631 are located in the middle area of the working table 7, the two reversing pieces 64 are located in the middle area of the working table 7, the risk that people touch the moving pieces such as the air cylinders 631 can be reduced, and the operation safety is improved.

Of course, in other embodiments, the shape of the table 7, the number of working areas and jigs 100, etc. may be adjusted.

In summary, the jig 100 of the present application can accurately position workpieces G1 such as a speaker net G11, and maintain the positioning result, so as to avoid damage, and different workpieces G1 can be positioned at the same position, that is, the positioning accuracy is high during repeated positioning. In order to illustrate the technical effect of the positioning device 6000 of the present application, a device (referred to as an existing device) for positioning the speaker network G11 in the prior art needs to be described first, and the existing device needs to be matched with a camera photographing system to determine the rotating position of the rotating platform, so that the speaker network G11 can be positioned, and the camera photographing is delayed, so that the cost of the rotating platform is high. The positioning device 6000 omits a photographing system and a rotary platform in the prior art, so that positioning time is saved, and the manufacturing cost of the device is low. With the positioning apparatus 6000 having a plurality of working areas, a plurality of workpieces G1 can be positioned at the same time, and the positioning efficiency is high.

It is apparent that the embodiments described above are only some embodiments of the present application, but not all embodiments, the preferred embodiments of the present application are given in the drawings, but not limiting the patent scope of the present application. This application may be embodied in many different forms, but rather, embodiments are provided in order to provide a more thorough understanding of the present disclosure. Although the present application has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing, or equivalents may be substituted for elements thereof. All equivalent structures made by the specification and the drawings of the application are directly or indirectly applied to other related technical fields, and are also within the protection scope of the application.
