[0001] The present invention relates to the technical field of transformer production, in particular to a transformer production lead assembly device and an assembly method thereof. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. It is basic equipment for power transmission and distribution and is widely used in industry, agriculture, transportation, urban communities and other fields. After production is completed, it needs to be transferred to the installation site for installation and the leads must be connected to the transformer to complete the final assembly work.

[0003] When connecting the lead to the transformer, you need to first strip the insulation layer of the lead end, apply conductive paste to the outside of the wire harness and wrap it with aluminum tape, and then use the equipment wire clamp to fix it to the connection post of the transformer. However, when stripping the insulation layer, the stripping shears may damage the wire harness due to excessive force, and when applying conductive paste, it may also affect the circuit due to uneven application.

[0015] Furthermore, the assembly method of the transformer production lead comprises the following steps: S1: First pull the aluminum tape from the material wheel, through the slot and through the opening to the bottom of the brush plate, and fix the end on the brush plate with glue; S2: Adjust the position of the limit plate according to the thickness of the insulation layer and put the sleeve onto the connecting end of the cable; S3: Rotate the turntable to make the cutter cut the insulation layer, and pull the sleeve to peel off the insulation layer; S4: During the stripping process, the sleeve is continuously rotated, and the conductive paste and aluminum tape are applied and wrapped onto the wire harness through the coating assembly.

The coating assembly 13 also includes a connecting rod 1313, a connecting rod 1313 is provided in the middle of the material storage box 1307, and one end of the connecting rod 1313 is connected to a return spring 1314, a pressure rod 1315 is sleeved on the outside of the connecting rod 1313, and the pressure rod 1315 is elastically connected to the connecting rod 1313 through the return spring 1314; The specific operation is as follows: when stripping the insulation layer, continuously rotate the turntable 11 to drive the sleeve 1 to rotate, and then press the pressure rod 1315 to squeeze the conductive paste onto the exposed surface of the wire harness, and spread the conductive paste evenly through the brush plate 1308 to avoid affecting the conductive effect due to uneven distribution of the conductive paste. While spreading the conductive paste evenly, the aluminum tape can be simultaneously wrapped around the wire harness coated with the conductive paste to facilitate the subsequent installation of the equipment wire clamp.

[0024] In summary, the transformer production lead assembly device and assembly method are as follows: when in use, first pull the aluminum tape from the material wheel 1302, pass it through the through slot 1306 and the through opening 1309, and fix the end to the bottom of the brush plate 1308. Then, open the material storage box 1307, fill it with conductive paste, press the pressure plate 1312 to pre-press the linkage rod 1311, so that the pressure plate 1310 is close to the conductive paste, and then close the material storage box 1307. Then, according to the thickness of the insulating layer, the gear ring 10 is rotated on the sleeve 1, so that the gear ring 10 drives the transmission wheel 205 to rotate, drives the threaded rod 204 to rotate, and then pushes the limit plate 202 to slide in the slot 201 through the threaded sleeve 203, and adjusts the position of the limit plate 202 to adapt to the cutting of insulating layers of different thicknesses. The symmetrical distribution of the transmission wheel 205 and the synchronous drive of the gear ring 10 can synchronously rotate all the threaded rods 204, thereby ensuring the synchronous movement of the limit plate 202 and the uniformity of the position adjustment, avoiding different cutting depths due to inconsistent positions and causing damage to the wiring harness. When the limit plate 202 moves, the cutter 6 can maintain connection with the limit plate 202 through the slide groove 7 and the slider 8 and restrict it, avoiding the limit plate 202 from deflecting when moving; The sleeve 1 is sleeved onto the lead end, and the ball 5 contacts the surface of the insulating layer to reduce the axial movement resistance. The pad 4 is tightly attached to the surface of the insulating layer under the action of the buffer spring 3. The turntable 11 is rotated on the sleeve 1, so that the turntable 11 pushes the pressure plate 207 axially close to the sleeve 1 through the pressure groove 12 and compresses the limit spring 206, driving the cutter 6 to press down, forming a longitudinal incision on the insulating layer. The limit rod 208 can limit the pressure plate 207 to prevent the pressure plate from deflecting during movement, and the limit rod 208 can slide in the turntable 11 through the pressure groove 12 without hindering the rotation of the turntable 11. When the cutter 6 is pressed down, the pressure plate 207 can drive the limit plate 202 to move synchronously with the cutter 6 through the threaded rod 204 and the threaded sleeve 203. When the cutter 6 penetrates the insulating layer, the limit plate 202 contacts the backing plate 4 to prevent the cutter 6 from moving further, thereby protecting the internal wiring harness and preventing the cutter 6 from causing damage to the wiring harness. At this time, under the obstruction of the limit plate 202 and the backing plate 4, the pressure plate 207 cannot move further. If the turntable 11 is continuously rotated, the turntable 11 can make the pressure plate 207 pass through the limit groove 12. The position rod 208 drives the sleeve 1 to rotate synchronously, so that the cutter 6 rotates around the lead with the sleeve 1, cutting the insulation layer horizontally and forming a complete annular incision, completely cutting off the insulation layer at the connection end of the lead. The ball 5 can reduce the movement resistance of the sleeve 1 when rotating on the outside of the lead. After the insulation layer is completely cut off, the turntable 11 continues to rotate and the sleeve 1 is pulled along the axis of the lead to peel off the cut insulation layer. The buffer spring 3 keeps the pad 4 pressed against the insulation layer fragments until the insulation layer is completely detached. When the material storage box 1307 is unable to move further, the pressure rod 1315 compresses the return spring 1314 and applies pressure to the pressure plate 1312, and the pressure plate 1312 can drive the pressure plate 1310 to press the conductive paste through the connecting rod 1311. The conductive paste is squeezed out and applied to the surface of the wiring harness from the material storage box 1307. As the turntable 11 drives the sleeve 1 to rotate, the bottom frame 1301 drives the material storage box 1307 to move synchronously with the sleeve 1 through the clamping plate 1304, so that the brush plate 1308 rotates around the lead to evenly spread the conductive paste on the surface of the wiring harness to avoid affecting the conductive effect due to uneven distribution of the conductive paste. While spreading the conductive paste, the end of the aluminum tape is adhered by the conductive paste. At the same time, as the brush plate 1308 moves, the aluminum tape is continuously pulled out from the material wheel 1302 and wound onto the surface of the conductive paste coating through the through slot 1306. The brush plate 1308 presses the aluminum tape tightly on the wiring harness to form a tight coating layer until the insulating layer is completely stripped off. At this time, the stripping of the insulating layer of the lead connection end, the coating of the conductive paste and the winding of the aluminum tape are completed. Loosen the turntable 11 and the pressure rod 1315, and the pressure plate 207 can rebound and reset under the action of the limit spring 206, and provide the pressure groove 12 to drive the turntable 11 to reset, and the pressure rod 1315 can also be reset under the action of the reset spring 1314. At the same time, the clamping plate 1304 drives the storage box 1307 to reset under the action of the tension spring 1305, which is convenient for the next use. After removing the sleeve 1 from the lead, the lead can be fixed to the transformer pile head through the equipment wire clamp to complete the assembly of the lead.
