The pushing tool 24 specifically includes a side plate 241 and a pushing plate 242, the side plate 241 being arranged on the pressure sensor 23, the pushing plate 242 being arranged on the side plate 241 close to one side of the bearing tool 21, more specifically, being arranged at the lower end of the side plate 241 to have a relatively low height and can act on the iron sheet 102 in the magnet assembly 100 more stably and accurately; the side wall lower end of the pushing plate 242 close to one side of the bearing tool 21 is provided with an abutting groove 240 for containing the iron sheet 102 at the upper part of the magnet assembly 100, the abutting groove 240 being at least partially contoured with the iron sheet 102, that is, the iron sheet 102 can at least partially extend into the abutting groove 240 and push the iron sheet 102 through the side wall of the abutting groove 240, which can prevent the iron sheet 102 from being misaligned or turned up when the pushing plate 242 translates, so as to ensure that the relative position of the iron sheet 102 and the magnet 101 is always accurate and the testing accuracy is ensured.

[0027] In the utility model, in combination with the drawings Figure 7 As shown, the magnet assembly 100 is placed in the positioning groove 210, the magnet 101 in the magnet assembly 100 is completely located in the positioning groove 210, and the upper end surface of the magnet 101 is flush with the upper end surface of the positioning groove 210, the iron sheet 102 in the magnet assembly 100 protrudes from the positioning groove 210 as a whole (the lower end surface of the iron sheet 102 does not extend into the positioning groove 210), the translation module 22 drives the pressure sensor 23 and the pushing tool 24 to translate, so that the pushing tool 24 abuts against the iron sheet 102, and the continued action of the translation module 22 overcomes the magnetic attraction force and / or adhesive force between the iron sheet 102 and the magnet 101, so that the iron sheet 102 completely separates from the magnet 101, in this process, the pressure sensor 23 is subjected to a counterforce and feeds back the data of the force, so as to measure the force when the iron sheet 102 and the magnet 101 separate in the binding surface direction, and feed back the transverse force on the binding surface when the magnet assembly 100 is "damaged", which can be used for sampling inspection of the magnet assembly 100 to confirm whether it meets the product control requirements.

[0028] The magnet 101 in the magnet assembly 100 is positioned completely through the positioning groove 210 on the bearing tool 21 in the above process, the flat pushing mechanism with the pressure sensor 23 acts on the iron sheet 102 connected with the magnet 101, the data fed back by the pressure sensor 23 when the iron sheet 102 is separated from the magnet 101 can be regarded as the combination force in the transverse direction of the two, and whether the combination force of the magnet assembly meets the requirements is judged through the combination force data.

In another application mode of the utility model, the magnet 101 and the iron sheet 102 form a magnet assembly as two products, that is, they are not fixedly connected, but are used as two components to test the combination force between them. For example, one component (which should be annular or circular) is placed on a mobile phone, and the other component (which should also be annular or circular) is placed on a mobile phone support. When the mobile phone on the mobile phone support needs to be separated from the mobile phone support, the mobile phone is translated to overcome the force between the magnet and the iron sheet. The combination force data between the two can further confirm the adhesion force value between the two and the mobile phone or the mobile phone support (from which the type or amount of glue is selected) to ensure stable connection.
