Tooling and fixture for wire mesh measuring sensor and usage method

Abstract

The invention discloses a tooling fixture for a wire mesh measuring sensor, which comprises a bottom plate; two splints, the splint surface has a slot whose depth can be adjusted to be the same as the thickness of the circuit board of the wire mesh measuring sensor; it is used for fixing the splint and The splint fixing device of the bottom plate, and the two splints are fixed in parallel and the direction of the slot is opposite; the position that is in contact with the wire to be welded of the wire mesh sensor is the two positioning strips of the zigzag groove, and the distance adjacent to the center of the sawtooth is metal The spacing of the wire array to be controlled; the pretension bolts on the clamping plate for tensioning the wire, determining the position of the wire and adjusting the pretension of the wire. The invention also discloses a using method based on the tooling fixture. The invention is simple and practical, can locate the position of the metal wire on the circuit board with high precision, and the pre-tightening force of the metal wire and the distance from the pad can be adjusted, avoiding false welding and virtual welding, and can be pre-wound and welded at one time , greatly saving manpower and welding time.

Description

technical field [0001] The invention relates to the field of tooling fixtures, in particular to a tooling fixture for wire mesh measuring sensors and a use method. Background technique [0002] Fixtures refer to devices used to clamp workpieces (or guide tools). [0003] During the welding process of the conductive wire mesh sensor, the spacing of the metal wire array of the wire mesh sensor is precisely controlled, so that the wire is completely attached to the surface of the circuit board pad, and a pre-tightening force is applied to it at the same time. Existing welding is to adopt traditional manual positioning of wire. The above positioning method has the following disadvantages: many people are required to cooperate, which wastes manpower; it is difficult to accurately control the distance between the wire mesh, resulting in errors; the metal wire to be welded does not necessarily fit the surface of the circuit board pad, resulting in errors; the solder joints are not...

Problems solved by technology

The above positioning method has the following disadvantages: it requires the cooperation of multiple people, which wastes manpower; it is difficult to accurately control the distance between the wire mesh, resulting in errors; the metal wire to be welded does not necessarily fit the surface of the circuit board pad, resulting in errors; the solder joints are not completely solidified when you let go , the cancellation of the pre-tightening force in the wire may cause slippage between the wire and the solder joint, resulting in false welding
