DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0021] Reference Figures 1-13As shown, the current transformer special efficient processing equipment provided by the embodiment of the application will be described in detail as follows: Referring to Figures 1-6 As shown, the current transformer special efficient processing equipment comprises a winding assembly, which comprises a C-shaped frame 11, a C-shaped ring 12 rotatably arranged on one side of the C-shaped frame 11, an axial hole 13 formed on the C-shaped ring 12 in the axial direction of the C-shaped ring 12, a wire storage wheel 14 detachably inserted into the axial hole 13, three supporting rollers 15 arranged in a triangular shape at the opening of the C-shaped frame 11, and a clamping jaw I 16 arranged between the three supporting rollers 15 and capable of being lifted.

[0022] When the core of the current transformer is wound, it is placed between the three supporting rollers 15, then the clamping jaw I 16 is lifted to clamp the pre-wound end of the enameled wire on the wire storage wheel 14, and then the clamping jaw I 16 is lowered from the middle of the core to below the core. The C-shaped ring 12 starts to rotate with the C-shaped frame 11 as the support, and the rotating path of the C-shaped ring 12 and the annular core are interpenetrated. Thus, when the C-shaped ring 12 drives the wire storage wheel 14 to continuously rotate around the core, the end of the enameled wire can be wound on the core with the clamping jaw I 16 as the traction anchor point. When winding, the core is supported by the supporting rollers 15 and rotates synchronously and slowly, realizing winding of the entire core. The wire storage wheel 14 comprises two parts of a wire wheel pre-wound with the enameled wire outside and a shaft rod rotatably connected at the shaft center of the wire wheel. After the shaft rod of the wire storage wheel 14 is inserted into the axial hole 13, the wire storage wheel 14 can be supported by the axial hole 13 and has the ability to rotate freely. When the enameled wire outside the wire storage wheel 14 is continuously wound on the core, the enameled wire will automatically rotate the wire storage wheel 14 to release the enameled wire.

[0023] It should be noted that the above implementation should meet two conditions: 1. The length of the enameled wire pre-wound on the wire storage wheel 14 each time should only meet the winding requirement of one core; 2. After the core is wound, the core is removed from the supporting rollers 15 and the next core to be wound is replaced, and the wire storage wheel 14 should simultaneously complete the steps of being detached from the axial hole 13, pre-wound with the enameled wire, and reloaded on the axial hole 13.

[0024] Thus, the device can avoid the situation that, in the prior art, after the core is replaced and placed, the enameled wire pre-wound on the winding ring is required to be wound on the core. The device overlaps the core replacement time and the enameled wire pre-winding time, thereby saving the preparation time and improving the work efficiency.

[0025] Referring to Figure 6 As shown, the current transformer special efficient processing equipment further comprises a tensioner, which comprises a friction block 21 abutting against the end of the wire storage wheel 14, and a spring 22 fixedly connected at both ends of the friction block 21 and the C-shaped ring 12.

[0026] The tensioner is used to realize the winding of the enameled wire, and the "tension" effect of the enameled wire makes the enameled wire winding more compact, and improves the processing quality. Specifically, when the storage wheel 14 is rotated by the enameled wire, the friction block 21 is abutted to one end of the wheel surface of the storage wheel 14 through the spring 22, the friction force is improved through the extrusion force between the two, so that the self-rotation resistance of the storage wheel 14 is improved, and the purpose of "tension" of the enameled wire is achieved. In the embodiment, the spring 22 should be arranged in the blind hole of the C-shaped frame 12, and the friction block 21 should be slidingly fitted at the hole of the blind hole. On the one hand, the blind hole can be used as a place for accommodating the spring 22, and on the other hand, the lateral supporting force of the hole to the friction block 21 improves the stability of the friction block 21 during work.

[0027] Referring to Figure 7 As shown in the figure, the high-efficiency processing equipment special for current transformers further includes a material preparation assembly, which includes a sliding table cylinder one 31, a rotating cylinder 32 fixedly installed on the sliding table of the sliding table cylinder one 31, a pneumatic shear 33 fixedly installed on the driving end of the rotating cylinder 32, a clamping jaw two 34 fixedly installed on the top of the pneumatic shear 33, a clamping jaw three 35 fixedly installed on the top of the clamping jaw two 34, and a flying fork winding machine 36 arranged at the terminal point of the moving direction of the sliding table of the sliding table cylinder one 31.

[0028] Further, the high-efficiency processing equipment special for current transformers further includes an operating table 71 for supporting the equipment. In the above structure, the C-shaped frame 11 and the flying fork winding machine 36 are respectively fixedly installed at the two ends of the top of the operating table 71, and the sliding table cylinder one 31 is fixedly connected to the top of the operating table 71 and located between the C-shaped frame 11 and the flying fork winding machine 36.

[0029] It should be noted that the material preparation assembly is a place for pre-winding the storage wheel 14, and the flying fork winding machine 36 included therein is a product of the prior art. The flying fork winding machine 36 is a kind of high-precision automatic winding equipment widely used in the field of electrical manufacturing. Its core working principle is to pass one end of the enameled wire coil through one end of the winding machine (in the embodiment, the enameled wire coil is placed on the standing rod on one side of the flying fork winding machine 36 on the top of the operating table 71), and then lead out to the wire outlet of the flying fork through the hollow channel in the flying fork. Then, the flying fork is driven to rotate at high speed by the servo system, and the ceramic nozzle is driven to rotate rapidly around the to-be-wound part as the axis, so as to pull the enameled wire to move, cooperate with the cooperation of the guard plate and the die, and accurately and orderly wind the coil wire on the surface of the part.

[0030] When pre-winding, firstly rotate the cylinder 32 to turn the pneumatic shears 33, the clamping jaw two 34 and the clamping jaw three 35 to the side facing the flying spool winding machine 36, the storage reel 14 is clamped on the clamping jaw two 34, and the specific clamping action is that the clamping jaw two 34 clamps one end of the storage reel 14, and the end is the end provided with the protruding shaft rod, then the flying spool winding machine 36 works to rotate the flying spool to the directly above and keep (here, the pre-set condition to be met is that the height of the clamping jaw three 35 is consistent with the wire outlet height when the flying spool is rotated to the directly above), then the slide table cylinder one 31 drives the clamping jaw three 35 to approach the flying spool, the clamping jaw three 35 clamps the enameled wire at the wire outlet of the flying spool, then the slide table cylinder one 31 adjusts the distance between the storage reel 14 on the clamping jaw two 34 and the flying spool to the appropriate position, and then the flying spool winding machine 36 drives the flying spool to rotate continuously, at this time, one end of the enameled wire will take the clamping jaw three 35 as the pulling anchor point and continuously pre-wind on the storage reel 14, when winding, the slide table cylinder one 31 should drive the storage reel 14 on the clamping jaw two 34 to continuously approach and move away from the flying spool winding machine 36, so that the enameled wire can be uniformly wound on the entire storage reel 14, after the winding length meets the requirements, rotate the flying spool to the directly below and keep (here, the pre-set condition to be met is that the height of the pneumatic shears 33 is higher than the wire outlet height when the flying spool is rotated to the directly below), the slide table cylinder one 31 drives the pneumatic shears 33 to approach the wire outlet, and then cuts the enameled wire, completing the purpose of pre-winding a section of enameled wire on the storage reel 14.

[0031] Referring to Figure 8 As shown, the high-efficiency processing equipment special for current transformers further includes a switching assembly, which includes a linear module 41 fixedly connected to the top of the operating table 71 and located on one side of the C-shaped frame 11, a slide table cylinder two 42 fixedly installed on the top of the sliding block of the linear module 41, a rotating clamping jaw 43 fixedly installed on the top of the slide table of the slide table cylinder two 42, and two clamp jaw claws 44 respectively fixedly connected to the two jaw claws of the rotating clamping jaw 43.

[0032] Further, the C ring 12, the slide table cylinder one 31 and the flying spool winding machine 36 are arranged on a straight line, the moving direction of the sliding block of the linear module 41 is parallel to the straight line, wherein the moving starting point of the sliding block is aligned with the position of the shaft hole 13 when the C ring 12 stops rotating, the moving end point of the sliding block is aligned with the position of the clamping jaw two 34, the moving direction of the slide table of the slide table cylinder two 42 is perpendicular to the moving direction of the slide table of the slide table cylinder one 31, and the height of the shaft hole 13 when the C ring 12 stops rotating is consistent with the height of the clamping jaw two 34 and the rotating clamping jaw 43.

[0033] In this embodiment, the adapter assembly is used for the transfer of the storage reel 14 between the C ring 12 and the pre-winding position, and at the same time, the auxiliary storage reel 14 is disassembled and assembled at the two positions. It should be noted that the linear module 41 is a product of the prior art. The linear module 41 is a standardized linear motion unit integrating transmission, guidance, and driving functions. The core consists of a guide rail (providing guidance), a ball screw or a synchronous belt (transmission component), a servo / stepping motor (power source), and a slider (load installation carrier). The working principle is that the transmission component is driven by the motor to drive the slider to move along the guide rail to realize high-precision reciprocating linear motion, and the displacement, speed, and positioning can be accurately controlled.

[0034] When the above components are working, the rotating clamp jaw 43 on the slide cylinder 42 is driven by the slider of the linear module 41 to move to the position aligned with the clamp jaw 34. Then the slide of the slide cylinder 42 drives the rotating clamp jaw 43 to approach the clamp jaw 34, and the clamp jaw 44 clamps the storage reel 14. Then the linear module 41 drives the rotating clamp jaw 43 to move to the position aligned with the shaft hole 13, and then the rotating clamp jaw 43 drives the clamp jaw 44 on the jaw teeth to rotate, thereby rotating the storage reel 14 by 90 degrees and arranging the cut-off enameled wire head in a horizontal state. Then the slide cylinder 42 drives the storage reel 14 on the rotating clamp jaw 43 to move towards the C ring 12 until the shaft rod of the storage reel 14 is inserted into the shaft hole 13. Then the clamp jaw 16 is raised to the same level as the rotating clamp jaw 43 and clamps the enameled wire head in a horizontal state (the necessary condition for clamping is that the clamp jaw 16 is in the same plane as the storage reel 14 after insertion). Then the clamp jaw 16 is lowered to reset, thereby realizing the preparation for winding the iron core. The automatic disassembly and pre-winding of the storage reel 14 avoid the manual pre-winding of the enameled wire in the prior art, thereby improving the work efficiency.

[0035] It should be noted that the structure of the clamp jaw 44 in this embodiment is designed specifically. When the clamp jaw 44 is closed, it looks like a ring-shaped clamp. When it clamps the storage reel 14, the closing gap between the two clamp jaws 44 can limit and maintain the position of the two wire heads of the pre-wound enameled wire. Specifically, as shown in Figures 9-11As shown, when the line storage wheel 14 is clamped, the vertical upward line head (temporarily recorded as line head a, which is the first to contact the line storage wheel 14 in the overall process of pre-winding the coil, and will be pressed deep by the coils wound layer by layer in the subsequent winding process. Obviously, if this line head is used as the anchor point end of the core winding, the pre-wound coil will be unable to release from the line storage wheel 14 and wind onto the core), clamped in the gap between the upper part of the clamp jaw 44, is opposite to the vertical downward line head (temporarily recorded as line head b, which is the line head of the pre-wound coil freely hanging downward after being cut by the lower pneumatic cutter 33, and is at the surface of the pre-wound coil in the overall process of pre-winding the coil. If this line head b is used as the anchor point end of the core winding, the pre-wound coil can be released from the line storage wheel 14 and wound onto the core layer by layer and turn by turn), clamped in the gap between the lower part of the clamp jaw 44. Under the above targeted design, when the clamp jaw 44 drives the line storage wheel 14 to rotate ninety degrees, as shown in Figure 11 As shown, (when viewed from the direction of facing the device, with the linear module 41 in front and the C ring 12 behind, at this time rotating ninety degrees clockwise), the surface line head b can be arranged in a horizontal state, facilitating the clamping of the line head by the clamp jaw 16 and improving the efficiency of the device.

[0036] Further, referring to Figure 5 As shown, the edge of the C ring 12 is uniformly matched with six grooved wheels 18, one end of the six grooved wheels 18 is rotationally connected with the C-shaped frame 11, one end of the C-shaped frame 11 is fixedly installed with a motor 2 19, the driving end of the motor 2 19 is fixedly installed with a belt pulley, the belt pulley and the two grooved wheels 18 adjacent to the belt pulley are externally jointly installed with a synchronous belt, the side of the synchronous belt facing the C ring 12 is in abutment with the ring surface of the C ring 12, the groove surface of the above-mentioned grooved wheels 18 and the edge of the C ring 12 are mutually engaged, and through the geometric constraint force, the C-shaped frame 11 realizes stable support for the rotation of the C ring 12. The rotation of the C ring 12 is driven by the friction between the synchronous belt and the C ring 12 through the rotation of the synchronous belt driven by the motor 2 19. The tensioning of the synchronous belt belongs to the prior art and will not be described in detail here.

[0037] Further, the axial direction of the three supporting rollers 15 is vertically upward and perpendicular to the axial direction of the C ring 12. The axial bottom end of one of the supporting rollers 15 is fixedly connected with a motor 1 151, which is used to drive the rotation of the supporting roller 15, thereby realizing the effect of driving the rotation of the core, as shown in Figure 3As shown, the bottom of the motor one 151 is provided with a slide rail for adjusting the translation position of the motor one 151, the bottom ends of the shafts of the remaining two supporting rollers 15 are all rotationally connected to the operation table 71, the bottom of the slide rail is fixedly connected to the operation table 71, an elastic element is arranged on the slide rail, which can translate and press the motor one 151 to the direction of the remaining two supporting rollers 15, so as to realize the stable support of the iron core.

[0038] Further, the bottom end of the clamping jaw one 16 is fixedly connected with a lifting cylinder 17, which is used for lifting the clamping jaw one 16, the operation table 71 is located between the three supporting rollers 15 and is provided with a through hole for the lifting passage of the clamping jaw one 16, and the lifting cylinder 17 is fixedly installed on the bottom of the operation table 71 and located below the through hole.

[0039] Further, referring to Figures 12-13 As shown, the current transformer special high-efficiency processing equipment further comprises a disassembling assembly for quickly disassembling and assembling between the wire storage wheel 14 and the C ring 12, which comprises a threaded hole 51 opened on the C ring 12 along the radial direction of the C ring 12, and an internal hexagonal bolt 52 threadedly connected in the threaded hole 51, wherein the bottom of the threaded hole 51 is through the shaft hole 13, the bottom of the internal hexagonal bolt 52 abuts on the shaft rod of the wire storage wheel 14, the disassembling assembly further comprises a sliding frame one 53 fixedly installed on the top of the C-shaped frame 11, a cylinder three 54 fixedly installed above the sliding frame one 53, a motor three 55 fixedly installed on the bottom of the telescopic end of the cylinder three 54, and an internal hexagonal wrench 56 fixedly installed on the driving end of the motor three 55, wherein the motor three 55 is slidingly connected on the sliding frame one 53 along the radial direction of the C ring 12, the internal hexagonal wrench 56 is aligned between the internal hexagonal bolt 52, and the axial directions of the two are consistent.

[0040] When the shaft rod of the wire storage wheel 14 is inserted into the shaft hole 13, the cylinder three 54 on the sliding frame one 53 continuously extends to push the motor three 55 to the shaft hole 13, until the internal hexagonal wrench 56 cooperates with the internal hexagonal bolt 52, and then the motor three 55 drives the internal hexagonal wrench 56 to rotate, thereby driving the internal hexagonal bolt 52 to rotate in the threaded hole 51, until it is screwed to the bottom and abuts on the shaft rod of the wire storage wheel 14, and the wire storage wheel 14 is inserted and assembled on the shaft hole 13 through the extrusion and fixation of the internal hexagonal bolt 52 on the shaft rod, and vice versa, which can release the internal hexagonal bolt 52 from the shaft rod, so as to achieve the effects of automatic insertion and unloading of the wire storage wheel 14 on the C ring 12.

[0041] Further, referring to Figures 12-13As shown, the current transformer special efficient processing equipment further comprises a brake assembly, which comprises an infrared sensor 61 fixedly installed on the top of the C-shaped frame 11, the infrared sensor 61 being used to identify the reflective marker points on the ring surface of the C ring 12, a carriage two 62 fixedly installed on the top of the C-shaped frame 11 and located on one side of the infrared sensor 61, a cylinder four 63 fixedly installed above the carriage two 62, and a friction brake block 64 fixedly installed on the bottom of the telescopic end of the cylinder four 63, wherein the friction brake block 64 is slidingly connected to the carriage two 62 in the radial direction of the C ring 12.

[0042] It should be noted that the reflective marker points need to be pre-set on the ring surface of the C ring 12, which can significantly improve the reflectivity of infrared light compared to other parts of the ring surface, so as to distinguish whether the reflective marker points are identified by using the intensity of the signal received by the infrared sensor 61. This belongs to the use of prior art, and will not be described in detail here. When the winding of the C ring 12 needs to be stopped, the reflective marker points are first identified by the infrared sensor 61, and then the feedback signal of the infrared sensor 61 is received by the control system, so as to instruct the motor two 19 to stop rotating, and at the same time instruct the cylinder four 63 to extend, so as to drive the friction brake block 64 to move on the carriage two 62 towards the C ring 12, until the friction brake block 64 abuts against the ring surface of the C ring 12, and the C ring 12 is immediately stopped and kept stable by the strong friction force. Through the cooperation of the infrared sensor 61 and the friction brake block 64, the C ring 12 can be accurately stopped, so as to achieve the accurate alignment between the inner hexagonal wrench 56 and the inner hexagonal bolt 52, and the alignment between the hoop jaw 44 and the wire storage wheel 14 when the rotary jaw 43 moves to one end of the linear module 41 and aligns with the shaft hole 13, which is helpful for the disassembly and pre-winding of the wire storage wheel 14.
