The wire-wrapping head 104 is used to spray an adhesive, preferably alcohol, onto the enamelled wire. The winding assembly 105 is used for clamping the tone gauge 8 and enabling the tone gauge 8 to rotate around the axis of the tone gauge 8, and when the tone gauge 8 rotates, the enameled wire with the adhesive is adhered on the tone gauge 8 and wound at one end of the tone gauge 8 along with the rotation of the tone gauge 8. The double-cutter wire cutting assembly 106 is used for cutting off the enameled wire wound on the tone gauge 8; the double-blade wire cutting assembly 106 includes a double-blade wire cutting cylinder 1061 and a double-blade mechanism 1062; the double-cutter mechanism 1062 is driven by the double-cutter wire cutting cylinder 1061 to move closer to or further away from the gauge wire positioning mechanism 1052. The baking component 107 is positioned on the side surface of the voice coil positioning mechanism 1052 and is used for baking the adhesive on the enamelled wire; preferably, the baking assembly 107 may be a hot air dryer.
In this embodiment, the wire winding assembly 105 includes an enamel wire feeding mechanism 1051, a tone gauge wire winding positioning mechanism 1052, a wire winding power mechanism and a tightening mechanism 1054. The gauge wire-winding positioning mechanism 1052 comprises a wire-winding rotating shaft 10522, and a positioning slot 10521 for placing the gauge 8 is arranged at the first end of the wire-winding rotating shaft 10522; when one end of the gauge 8 is wound, the other end of the gauge 8 is inserted into the positioning groove 10521. The winding power mechanism comprises a winding cylinder 10531 and a winding motor 10532, and the winding cylinder 10531 drives the winding motor 10532 to approach or depart from a winding rotating shaft 10522: when the winding motor 10532 is close to the winding shaft 10522, the driving end of the winding motor 10532 is connected to the second end of the winding shaft 10522, and when the winding motor 10532 is far away from the winding shaft 10522, the driving end of the winding motor 10532 is separated from the second end of the winding shaft 10522. The propping mechanism 1054 is positioned at one side of the tone gauge winding positioning mechanism 1052 away from the winding power mechanism; when one end of the gauge 8 is wound, the tightening mechanism 1054 tightens the gauge 8 in the positioning groove 10521, and rotates the gauge 8 along with the positioning groove 10521.
Specifically, the operating principle of the winding unit 1 is as follows:
(1) an operator guides the enameled wire onto the wire guide plate 108 according to a line arrangement, and then inserts one end of the tone gauge 8 into a positioning groove 10521 in a tone gauge wire positioning mechanism 1052 located in the feeding station;
(2) the material detection component 102 detects that the tone gauge 8 is inserted, and the winding turntable 101 starts to rotate;
(3) when the gauge 8 rotates to the corresponding station of the gauge resetting assembly 103, the positioning cylinder 1031 extends out, and the buffer block 1032 pushes the gauge 8 to the bottom of the positioning groove 10521;
(4) the winding turntable 101 continues to rotate, the tone gauge 8 rotates to a winding station opposite to the propping mechanism 1054, the winding nozzle 104 sprays adhesive, and meanwhile, the propping mechanism 1054 is ejected, so that the tone gauge 8 is clamped by the propping mechanism 1054 and the positioning groove 10521;
(5) the winding cylinder 10531 extends out, and the winding motor 10532 is connected with the winding rotating shaft 10522;
(6) starting a winding motor 10532, and enabling the tone gauge 8 to rotate along with a winding rotating shaft 10522, wherein an enameled wire is stuck to the outer wall of the tone gauge 8 and then wound on the tone gauge 8 along with the rotation of the tone gauge 8 due to the fact that an adhesive is sprayed on the enameled wire;
(7) the winding number of the enamelled wire reaches a preset value, the winding cylinder 10531 is retracted, and the winding turntable 101 continues to rotate until the tone gauge 8 is positioned below the double-scissor mechanism 1062;
(8) the double-cutter wire cutting cylinder 1061 moves downwards, and then the double-cutter mechanism 1062 cuts off the enamelled wires at two sides of the tone gauge 8; specifically, except for the first and the last tone gauges 8, one end of the enameled wire on each tone gauge 8 in the middle is connected with the enameled wire of the previous tone gauge 8, and the other end of the enameled wire is connected with the enameled wire of the next tone gauge 8, so that only the enameled wires at the two ends of the voice coil with the number of two are needed to be cut off, for example, the enameled wires of the five connected voice coils are needed to be disconnected, and only the enameled wires at the two ends of the second voice coil and the fourth voice coil are needed to be cut off;
(9) the winding turntable 101 continues to rotate to a baking station, and the baking assembly 107 is used for baking the adhesive, so that the adhesive can be dried quickly, and the purpose of adhering the enameled wire can be achieved.
As shown in fig. 8, the first transfer table 2 includes, in order from bottom to top, a first transfer motor, a first transfer plate 201, and a first transfer cylinder 202. The first rotating plate 201 rotates under the driving of the first transfer motor, the first transfer cylinder 202 is fixed on the first rotating plate 201, and the driving end of the first transfer cylinder 202 is connected with an insertion boss. When the tone gauge 8 on the winding turntable 101 is turned to the transfer station aligned with the first transfer table 2, the first transfer cylinder 202 is extended, the insertion boss is inserted into the tone gauge 8, then the first transfer cylinder 202 is retracted, the tone gauge 8 is moved away from the tone gauge winding positioning mechanism 1052, the first transfer motor controls the first transfer plate 201 to rotate 180 °, then the first transfer cylinder 202 is extended, and the tone gauge 8 is sent to the tone gauge positioning mechanism 3013 of the wire cutting unit 3. Preferably, the number of the first transfer cylinders 202 may be one or two.
The wire cutting unit 3 is used for cutting off the wire ends of the short enameled wires. The wire cutting unit 3 includes a position pre-adjustment assembly 301 and a single blade wire cutting assembly 303. The position pre-adjustment assembly 301 is used for rotating the gauge 8 to rotate the wire end on the gauge 8 to a preset position.
In this embodiment, as shown in fig. 8, the position pre-adjustment assembly 301 includes a positioning dial 3011 and a probe mechanism 3012. A plurality of tone gauge positioning and positioning mechanisms 3013 are fixedly arranged in the circumferential direction of the positioning turntable 3011. The wire probing mechanism 3012 is positioned at one side of the positioning rotary table 3011 and is used for increasing the included angle between two wire ends of the enameled wire; the probe mechanism 3012 includes a probe cylinder 30121, a probe motor 30122, a tensioning shaft 30123, and a probe 30124. The line detecting motor 30122 is driven by the line detecting cylinder 30121 to approach or depart from the position adjusting rotary disc 3011; one end of the tensioning shaft 30123 is connected with the driving end of the probe motor 30122, and the other end of the tensioning shaft is used for being inserted into the tone gauge 8; the probe 30124, when the tone gauge 8 rotates along with the tensioning shaft 30123, the probe 30124 is used to block the wire ends of the enameled wires on the tone gauge 8 from rotating. Specifically, since the single-blade wire cutting assembly 303 is processed by each wire end, it is desirable to make the included angle between the two wire ends of the enamel wire larger, and the optimal way is to make the two wire ends on a straight line, one left to right or one up to down. After the double-blade trimming assembly 106 trims the two wire ends on the gauge 8 should beThe structure of the voice gauge 8 is inclined downwards in an eight-shaped structure, after the wire ends are baked, the wire ends are deformed by heat, and the two wire ends on the voice gauge 8 can be changed into the structure of the II-shaped structure to be vertically downwards, which is not beneficial to the subsequent single-cutter wire cutting operation. Therefore, when the positioning rotary disc 3011 rotates to the probe station, the probe cylinder 30121 stretches out, the tensioning shaft 30123 stretches into the tone gauge 8, and the probe 30124 is inserted into the space between the wire end and the tone gauge 8; the probe motor 30122 drives the gauge 8 to rotate, and when the gauge 8 rotates, the wire ends will rotate, but due to the blocking of the probe 30124, the gauge 8 rotates and the wire ends do not rotate, so that the blocked wire ends will change from the 'II' type to the 'one' type structure horizontally leftwards, then the gauge 8 is rotated in the opposite direction, and the other wire ends will also change to the 'one' type structure horizontally rightwards due to the blocking of the probe 30124. The sound gauge 8 treated by the probe and the two enamelled wire ends form a structure similar to a reverse structure ""shape. Preferably, the probe 30124 is fixed at the driving end of the probe cylinder 30125, and the height of the probe 30124 can be controlled by controlling the extension of the probe cylinder 30125, so that the adjustment is convenient.
