Hollow coil winding equipment

Abstract

The invention relates to hollow coil winding equipment, which solves the technical problem that the heating time is long and the cost is high in the prior art. The hollow coil winding equipment comprises a bobbin unit, a stand arranged at one side of the bobbin unit and a plurality of winding fixtures. A mounting base is arranged on the stand. A plurality of main shafts which correspond to the winding fixtures one to one and which are connected with the winding fixtures in a rotary manner are arranged on the mounting base. A plurality of counter shafts which correspond to the winding fixtures one to one and which can be used for driving the winding fixtures to rotate are arranged on the mounting base. The equipment further comprises a heating system which can be used for heating the two ends of wound coils and the wound coils wound on the winding fixtures. The equipment further comprises a tension control system for enabling the two ends of the wound coils to have constant tension while the wound coils are continuously wound on the winding fixtures. The invention has the advantages that the hollow coil winding equipment could greatly reduce the heating time, and is low in cost and stronger in practicability.

Description

technical field [0001] The invention belongs to the technical field of winding equipment, in particular to an air-core coil winding equipment. Background technique [0002] When the existing winding machine winds the coil, generally one end of the wire is fixed first, and then the wire is started to be wound on the winding jig, and the wire is cut by the cutting mechanism after winding to a set length. Later, some inventors used the α winding method to wind the wire. The middle part of the wire to be wound was wound on the wire winding jig first, and then the two ends of the wire to be wound were continuously wound on the wire winding jig. Such an air-core coil is more practical and has a wider application range. However, no matter the above two winding schemes, there are at least the following defects: in the process of winding, only one heating pair is heating the winding jig, and then the coiled wire is heated by the heating temperature of the winding jig. Heating is ca...

Problems solved by technology

However, no matter the above two winding schemes, there are at least the following defects: in the process of winding, only one heating pair is heating the winding jig, and then the coiled wire is heated by the heating temperature of the winding jig. Heating is carried out to complete self-adhesion, and the double-ended hollow coil is finally processed. When winding the coiled wire, the coiled wire is tensioned by a tensioner or a servo motor.

The above-mentioned method can meet the production requirements to a certain extent, but the above-mentioned method also has at least the following defects: the heating process takes a long time and the winding operation cannot be started immediately after the winding machine is turned on. The running energy consumption of the machine is high and the service life of the winding fixture is short, which virtually reduces the practicability of the winding machine. Secondly, the structure of using a tensioner or a servo motor to tension the wound wire is not only costly tall and bulky

[0004] Although the above-mentioned scheme improves the prior art to a certain extent, the scheme also has at least the following defects: it fails to completely solve the above-mentioned technical problems, and still has the technical problems of long heating time and high cost, which virtually reduces the winding time.
