Technical Field
[0001] The invention belongs to the technical field of copper core rubber coated wire production, in particular to a copper core wire finishing device. Background Art
[0002] Copper core rubber coated wire has been widely used in high-frequency electronic transformers for new energy vehicle charging piles. The quality of copper core wire, the main raw material for producing copper core rubber coated wire, is particularly important. In fact, copper core wire is produced by drawing, and the quality characteristics of the entire copper core wire will vary. Therefore, the first step in the production of copper core rubber coated wire in the existing technology is to select and sort the copper core wire. The selection can only be checked with primitive measuring tools; sorting is usually done by dynamic wire pulling by a winding machine, but in the process of pulling the wire, the tensile strength of the copper core wire is often too high, causing the copper core wire to deform, and unqualified copper core wires cannot be automatically identified. Summary of the invention
[0003] In order to make up for the shortcomings of the prior art, the present invention proposes a copper core wire sorting device, which is mainly used to solve the problem that the copper core wire winding machine in the prior art easily causes excessive pulling strength when winding the copper core wire, resulting in deformation of the copper core wire. At the same time, it can also automatically identify unqualified copper core wires.
[0004] The technical solution adopted by the present invention to solve its technical problem is: the copper core wire arranging equipment described in the present invention comprises a frame, a pay-off wheel, a guide wheel, a take-up arranging wheel, a copper core wire identification device and an arranging equipment controller; the characteristics are: the pay-off wheel is located below the frame, and the copper core wire is wound on the pay-off wheel; the guide wheel is a single-slot fixed pulley, fixed on the upper part of the frame, and its lower part is opposite to the pay-off wheel position; the take-up arranging wheel is a four-slot fixed pulley, fixed on the upper part of the frame and consistent with the installation level of the guide wheel; the copper core wire identification device comprises an adjusting lever, A tensioning wheel, a left counterweight, a right counterweight, an upper limit column, a displacement sensor and a lower limit column; a fulcrum hole is provided in the middle of the adjusting lever, and the fulcrum hole is fixed to the lower part of the frame through a rotating pin; the tensioning wheel is a three-groove movable pulley, which is fixed to the end of the right lever arm of the adjusting lever through a rotating shaft; the left counterweight is sleeved on the left lever arm of the adjusting lever, and can slide relatively along the length direction of the left lever arm to adjust the counterweight balance; the right counterweight is sleeved on the right lever arm of the adjusting lever, and can slide relatively along the length direction of the right lever arm to adjust the counterweight balance; The upper limit column is fixed above the left force arm of the adjusting lever, and an upper pressure sensor is provided on the upper limit column; the displacement sensor is fixed at the horizontal end point position of the left force arm end of the adjusting lever; the lower limit column is fixed below the left force arm of the adjusting lever, and a lower pressure sensor is provided on the lower limit column; the upper pressure sensor, displacement sensor and lower pressure sensor are all connected to the sorting equipment controller via cables.
[0005] The copper core wire on the pay-off wheel is turned through the single groove of the guide wheel, horizontally enters the first groove of the take-up and sorting wheel, wraps around downward, enters the first groove of the tensioning wheel of the copper core wire identification device, wraps around half a circle at the bottom, and then detours to the second groove of the take-up and sorting wheel, wraps around half a circle on the second groove of the take-up and sorting wheel, enters the second groove of the tensioning wheel of the copper core wire identification device again, wraps around half a circle under the second groove of the tensioning wheel for the third time, wraps around half a circle on the third groove of the take-up and sorting wheel, enters the third groove of the tensioning wheel of the copper core wire identification device for the third time, wraps around half a circle under the third groove of the tensioning wheel for the fourth time, and enters the fourth groove of the take-up and sorting wheel after wrapping around the fourth groove of the take-up and sorting wheel, and then enters the next process.
[0006] Compared with the prior art, the present invention sets a three-slot tensioning wheel and a four-slot wire-collecting and sorting wheel, so that the copper core wire that is wound back and forth between them continuously changes from a U-shape to a straight shape. The tensioning wheel is pulled to exert an upward force on the right lever arm of the adjusting lever to change the balance of the adjusting lever. When the pulling strength of the copper core wire is too large, the left lever arm end of the adjusting lever deviates downward significantly and directly presses the lower limit column for a long time. The lower pressure sensor sends a signal, so that the sorting equipment controller sends a warning and a shutdown command. The problem that the copper core wire winding machine in the prior art is prone to excessive pulling strength when winding the copper core wire, resulting in deformation of the copper core wire, is solved. At the same time, the present invention also uses the principle that the flexibility of the copper core wire changes with different wire diameters. The copper core wire continuously changes from a U-shape to a straight shape and the tensioning wheel is pulled to change the balance of the adjusting lever, so as to realize automatic identification of unqualified copper core wires.

DETAILED DESCRIPTION
[0010] In this embodiment, refer to Figure 1 , Figure 2A copper core wire sorting device, comprising a frame 1, a pay-off wheel 2, a guide wheel 3, a take-up sorting wheel 4, a copper core wire identification device and a sorting device controller 5; the pay-off wheel 2 is located below the frame 1, and a copper core wire 6 is wound around the pay-off wheel 2; the guide wheel 3 is a single-groove fixed pulley, fixed to the upper part of the frame 1, and its lower part is directly opposite to the pay-off wheel 2; the take-up sorting wheel 4 is a four-groove fixed pulley, fixed to the upper part of the frame 1 and consistent with the installation level of the guide wheel 3; the copper core wire identification device comprises an adjusting lever 7, a tensioning wheel 8, a left counterweight block 9, a right counterweight block 10, The upper limit column 11, the displacement sensor 12 and the lower limit column 13; the middle part of the adjusting lever 7 is provided with a fulcrum hole, and the fulcrum hole is fixed to the lower part of the frame 1 through a rotating pin 14; the tensioning wheel 8 is a three-groove movable pulley, which is fixed to the right arm end of the adjusting lever 7 through a rotating shaft; the left counterweight block 9 is mounted on the left arm of the adjusting lever 7, and can slide relatively along the length direction of the left arm to adjust the counterweight balance; the right counterweight block 10 is mounted on the right arm of the adjusting lever 7, and can slide relatively along the length direction of the right arm to adjust the counterweight balance; The upper limit column 11 is fixed above the left force arm of the adjusting lever 7, and an upper pressure sensor 15 is provided on the upper limit column 11; the displacement sensor 12 is fixed at the horizontal end point position of the left force arm end of the adjusting lever 7; the lower limit column 13 is fixed below the left force arm of the adjusting lever 7, and a lower pressure sensor 16 is provided on the lower limit column 13; the upper pressure sensor 15, the displacement sensor 12 and the lower pressure sensor 16 are all connected to the sorting device controller 5 via cables.
[0011] The copper core wire on the pay-off wheel 2 is turned through the single groove of the guide wheel 3, horizontally enters the first groove of the take-up and sorting wheel 4, wraps around downward, enters the first groove of the tensioning wheel 8 of the copper core wire identification device, wraps around half a circle at the bottom, and then detours to the second groove of the take-up and sorting wheel 4, wraps around half a circle on the second groove of the take-up and sorting wheel 4, enters the second groove of the tensioning wheel 8 of the copper core wire identification device again, wraps around half a circle under the second groove of the tensioning wheel 8 for the third time, wraps around half a circle on the third groove of the take-up and sorting wheel 4, enters the third groove of the tensioning wheel 8 of the copper core wire identification device for the third time, wraps around half a circle under the third groove of the tensioning wheel 8 for the fourth time, and enters the fourth groove of the take-up and sorting wheel 4 after wrapping around the fourth groove of the take-up and sorting wheel 4, and enters the next process.
[0012] Furthermore, a first adjusting bolt 17 is provided on the left counterweight block 9, and the left counterweight block 9 can be locked on the left lever arm of the pre-adjusted position by the first adjusting bolt 17; a second adjusting bolt 18 is provided on the right counterweight block 10, and the right counterweight block 10 can be locked on the right lever arm of the pre-adjusted position by the second adjusting bolt 18.
[0013] During normal operation, the copper core wire 6 entering the sorting device is pulled by the traction force of the next process. Because it continuously changes from a U-shape to a straight shape between the tensioning wheel 8 and the wire-receiving sorting wheel 4 of the sorting device, the copper core wire 6 is under changing pressure. The changing pressure generated by the copper core wire 6 changing from a U-shape to a straight shape each time it wraps around is superimposed on the bottom of the tensioning wheel 8, which is equivalent to applying an upward force to the right lever arm of the adjusting lever 7; if the wire diameter of the copper core wire 6 is uniform and standard, and the material flexibility is consistent, the upward force applied to the right lever arm of the adjusting lever 7 is constant; by adjusting the counterweight blocks on the lever arms at both ends of the adjusting lever 7, the adjusting lever 7 is in a dynamic horizontal state; at this time, the displacement sensor 12 at the horizontal end point of the left lever arm of the adjusting lever 7 detects a balance signal; the sorting device controller 5 issues an instruction to maintain normal operation.
[0014] When the pulling strength of the copper core wire 6 entering the sorting device is too large, the copper core wire 6 continuously changes from a U-shape to a straight shape between the tensioning wheel 8 and the wire-reeling sorting wheel 4 of the sorting device, and the upward force applied to the right force arm of the adjusting lever 7 becomes larger; the tensioning wheel 8 is pulled up; by adjusting the lever 7, the left force arm end will deviate downward from the horizontal end point position significantly and directly press and touch the lower limit column 13 for a long time, and the lower pressure sensor 16 sends a signal, so that the sorting device controller 5 sends an alarm signal that the copper core wire pulling strength is too large, and controls the system to shut down.
[0015] When the copper core wire 6 entering the sorting equipment has a slightly uneven wire diameter and the flexibility of different wire diameters changes, the copper core wire 6 continuously changes from a U-shape to a straight shape between the tensioning wheel 8 and the wire-winding sorting wheel 4 of the sorting equipment, and the tensioning wheel 8 is pulled and applied to the upward force of the right lever arm of the adjusting lever 7, which changes; the dynamic horizontal state of the adjusting lever 7 changes immediately; the left lever arm end of the adjusting lever 7 deviates from the horizontal endpoint position, and the displacement sensor 12 loses the balance signal; the sorting equipment controller 5 issues a correction operation instruction, and the system stretches and corrects the copper core wire 6 by changing the traction force of the next process, and finally makes the wire diameter uniform.
[0016] When the copper core wire 6 entering the sorting equipment has an uneven wire diameter, which exceeds the ability to stretch and correct the copper core wire 6 by changing the traction force of the next process, the copper core wire 6 continuously changes from a U-shape to a straight shape between the tensioning wheel 8 and the wire-reeling sorting wheel 4 of the sorting equipment, and the upward force applied to the right lever arm of the adjusting lever 7 by the tensioning wheel 8 will change significantly; the left lever arm end of the adjusting lever 7 will intermittently jump and touch the lower limit column 13 after deviating from the horizontal end point position, and the lower pressure sensor 16 will send out an intermittent jumping signal, and the displacement sensor 12 will also lose the balance signal; the sorting equipment controller 5 will send out an alarm signal that the copper core wire is unqualified, and the system will be shut down.
[0017] When the copper core wire 6 on the tension wheel 8 breaks and loses the lower winding traction force and falls, the left lever arm is lifted up and blocked by the upper limit column 11, triggering the upper pressure sensor 15, so that the finishing equipment controller 5 issues a warning and a shutdown command.
[0018] In addition, the above embodiments are only illustrative of the principles and effects of the present invention. For those skilled in the art, a number of modifications and improvements made without departing from the creative concept of the present invention are within the protection scope of the present invention.
