AI Technical Summary
During the winding process of existing relay winding machines, the winding trajectory of the enameled wire is chaotic, resulting in inconsistent number of enameled wire turns wrapped in various parts of the coil frame, affecting the quality of the relay. The armature may loosen after multiple openings and closings, resulting in a decrease in contact pressure and a poor anti-bounce performance.

Description
Technical Field
[0001] The present invention mainly relates to the technical field of relays, and in particular to a winding mechanism of a relay and equipment using the same. Background Art
[0002] A relay is an electrical control device. When the change of the input quantity (excitation quantity) reaches the specified requirement, it causes the controlled quantity to undergo a predetermined step change in the electrical output circuit. It has an interactive relationship between the control system (also known as the input circuit) and the controlled system (also known as the output circuit). It is usually used in automated control circuits. It is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic adjustment, safety protection, and circuit conversion in the circuit.
[0003] The prior art mainly uses a winding machine to wind the coil frame. However, during the winding operation of the coil frame by the prior winding machine, the winding trajectory of the enameled wire is chaotic, resulting in inconsistent numbers of turns of the enameled wire wound around various parts of the coil frame, which ultimately affects the quality of the assembled relay. In addition, after the relay is repeatedly opened and closed, the armature may become loose, which reduces the contact pressure of the moving and static contacts, deteriorates the anti-bounce performance, and has poor protection.

The first motor 41 drives the rotating disk 11 to rotate, with The movable mounting chassis 2 rotates, the enameled wire 14 is wound, the second motor 42 and the motor inside the motor box 73 are started, driving the lead screw 5 to rotate, so that the movable plate 51 moves up and down at a uniform speed, and the hook 76 moves accordingly, driving the enameled wire 14 to move up and down at a uniform speed, so that the winding trajectory of the enameled wire 14 is stable, and the number of turns of the enameled wire 14 wound around each part of the iron core 21 is consistent, thereby ensuring the quality of the relay finally assembled. After the winding of the iron core 21 is completed, the mounting chassis 2 is removed, and the shell 67, the iron core 21, the mounting chassis 2, the assembly 6 and the shell 67 are assembled. The non-magnetic gasket 66 can improve the protection of the armature 62 and avoid damage to the armature 62. The rebound when the contact is closed can be avoided by limiting the adjustment screw 65, and the reset spring 63 does not directly contact the reed, but the adjustment screw 65 directly contacts the reed, and no short-term adaptive deformation occurs, and the anti-rebound performance is better.
