For example It is said that the magnetic element 431c1 of the stopper portion 431c is an electromagnet, and the magnetic element 341 of the jig frame 340 contains a ferromagnetic material. When the jig frame 340 is engaged with the guide rail 431, the magnetic element 341c1 of the limiting portion 431c provides appropriate magnetic attraction to the magnetic element 341 of the jig frame 340, so that the jig frame 340 can smoothly pass over the carrying portion 131a. Floating also favors the alignment between the positioning holes 151 of the carrier 150 and the positioning pins 121 of the lower jig 120. In addition, the magnetic element 431c1 of the limiting portion 431c provides a large magnetic attraction to the magnetic element 341 of the jig frame 340, and the purpose of locking the jig frame 340 to the limiting portion 431c is also achieved. The locking mechanism 132 shown in Fig. 4 can be effectively replaced.

In some other embodiments, the magnetic element 431c1 provided in the limiting portion 431c may also be provided with the air blast hole 231a1 or the seventh hole provided in the bearing portion 231a in the ball 131a1 and the sixth figure provided in the carrying portion 131a in FIG. The maglev elements 331a1 provided in the carrying portion 331a are combined in the drawing.

From the above detailed description of the specific embodiments of the present disclosure, it can be clearly seen that in the transfer type electric measuring device of the present disclosure, the transfer module can be moved to the off-machine position relative to the rack body, The manual or mechanical arm is used for the boarding process (that is, the fixture frame with the carrier plate is installed in the transfer module). After the boarding process is completed, the transfer module is then moved to the internal position of the rack body with the jig frame to test the board to be tested in the transfer type electric measuring device, and thus Ergonomic or automated production line planning. Moreover, the transfer module is provided with a guide frame which can guide the jig frame and can be moved to be restricted between the guide rails (that is, the guide rail can hold the jig frame, but the jig frame is still left) The degree of freedom of two-dimensional movement or three-dimensional movement) can compensate for the alignment tolerance of the carrier and the lower fixture during installation. By the foregoing structural configuration, the transfer type of the present disclosure The electrical measuring equipment can achieve at least the following purposes: (1) reducing the difficulty of alignment of the carrier with the lower fixture; and (2) reducing the wear of the positioning pin of the lower fixture and the positioning hole of the carrier to increase the lowering The service life of the fixture and the carrier.

Although the present disclosure has been disclosed in the above embodiments, it is not intended to limit the present disclosure, and any person skilled in the art can make various changes and refinements without departing from the spirit and scope of the present disclosure. The scope of protection of the disclosure is subject to the definition of the scope of the appended patent application.
