It can be understood that the limiting portion 51 and the positioning portion 52 of the positioning element 5 can be fixedly connected, for example, by welding, interference, and integral forming, so as to improve the installation stability of the positioning element 5. Of course, in other embodiments, the limiting portion 51 and the positioning portion 52 may also be detachably connected, for example, by a snap connection, a plug-in fit, a screw connection, or a pin connection, so as to improve the convenience of assembling and disassembling the positioning element 5, which is not limited herein.
In the bending tool 100, the base 1 can be made of metal, and the edges or corners of the placing groove 12 are provided with round corners or chamfer structures, so that the thickness of the FPC is larger than or equal to that of the round corners or chamfer structures. The material of the positioning piece 5 can be selected from metal and plastic, and the end part of the positioning part 52 of the positioning piece 5 is provided with a fillet or chamfer structure, so that the fillet or chamfer structure is larger than or equal to the thickness of the FPC. The material of the bending pressing block 2 can be selected to be a metal material, and the edge part of the pressing table 21 of the bending pressing block 2 is provided with a fillet or a chamfer structure, so that the fillet or the chamfer structure is larger than or equal to the thickness of the FPC. The edges and corners of the bending groove 12 of the base 1 are provided with round corners or chamfer structures, so that the thickness of the FPC is larger than or equal to that of the round corners or chamfer structures.
The invention further provides detection equipment, which comprises an equipment main body and the bending tool 100, wherein the bending tool 100 is arranged on the equipment main body. The specific structure of the bending tool 100 refers to the foregoing embodiments, and since the detection device adopts all technical solutions of all the foregoing embodiments, all beneficial effects brought by the technical solutions of the foregoing embodiments are at least achieved, and are not repeated here.
The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
