Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1-3, in the magnet height detection device in this embodiment, a position sensor 300 is used to detect the height of a magnet assembled on a pen cover, the position sensor 300 is disposed on an operating element 202 that can be driven manually or by a mechanism, the operating element 202 is correspondingly disposed with the position sensor 300 along the arrangement direction of the magnet, so that the height of each magnet can be detected, the type of the position sensor 300 can be selected according to actual requirements, in some embodiments, a metal inductive probe is used, for process requirements with higher precision requirements, a laser sensor and the like can be used, and it is worth mentioning that before starting the test, each position sensor 300 needs to be adjusted manually to be on the same horizontal reference.
In order to conveniently place a workpiece to be detected, the workbench 100 with a workpiece fixing position is provided, the position sensor 300 is arranged on the mounting assembly 200, the mounting assembly 200 comprises a supporting member 201 and an operating member 202, in the embodiment, the supporting member 201 is a fixing plate which is higher than the table top of the workbench 100, the supporting member 201 avoids the workpiece fixing position, the operating member 202 is movably arranged on the supporting member 201, and when the workpiece is placed, the operating member 202 can be moved away so as not to shield the workpiece fixing position.
