Description

Technical Field

[0001] This utility model relates to the field of automation equipment, and in particular to a dual-axis OBC coil winding device. Background Technology

[0002] In today's market, most windings are made by winding wire turns on a bobbin, with copper wire being the most common type of wire. Most products of this type of winding have one or more copper wires wound around a single bobbin, while a smaller number of products have them continuously wound around different bobbins.

[0003] The prior art (announcement number: CN119092292A, announcement date: 2024.12.06) discloses a tape wrapping mechanism suitable for fine wires, which can be compatible between a winding mechanism and a sleeve feeding mechanism. In other words, it can be close to the winding mechanism, and thus can utilize the clamping effect of the winding mechanism on the copper wire, thereby avoiding the overlapping of copper wires.

[0004] However, the insulation of the outer surface of existing copper wires before winding on the wire frame is generally poor. When winding with high current and voltage, copper wires are prone to overlapping, causing the winding to fail to perform its corresponding function. Therefore, it is necessary to apply adhesive insulation during the copper wire transportation process. In addition, the loading and unloading of the wire frame before winding copper wires on the wire frame are done manually, which is inefficient. Moreover, the outer circumference of the copper wire is generally not wrapped with tape for insulation treatment. Therefore, it is necessary to design a dual-axis OBC coil winding equipment to solve the technical defects of low production efficiency and poor production quality. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model provides a technical solution that can solve the above problems.

[0006] A dual-axis OBC coil winding device includes a frame, with feeder frames on both the left and right sides of the frame, and two main coils installed inside the feeder frames;

A base plate is connected to the three-axis conveying mechanism, and a wire feeding machine is fixedly installed on the base plate. After passing through the wire feeding machine, the wire cores in the wire feeding frame are wound one by one on the main shaft of the first wire frame and the main shaft of the second wire frame.

A feeding mechanism is fixedly installed on the lower side of the base plate on the left side. The feeding mechanism unloads the wire core onto the first wire frame main shaft and the second wire frame main shaft after winding, and conveys it to the feeding conveyor for output.

[0011] Furthermore: The feeding mechanism and the unloading mechanism have the same structure, each including two displacement devices, two displacement plates, a rotating shaft, a rotary cylinder, and a gripper cylinder. The displacement devices are fixedly installed on the lower side of the base plate. The displacement devices drive the displacement plates to move closer to or away from the first wire frame main shaft and the second wire frame main shaft. The rotating shaft is rotatably installed between the two displacement plates. The two gripper cylinders are fixedly installed at the left and right ends of the rotating shaft.

[0014] Furthermore: The first tape wrapping machine includes a shifting mechanism, a positioning bracket, a tape roller, a clamping mechanism, and a cutting mechanism. The shifting mechanism is fixedly installed on the side plate. The shifting mechanism drives the positioning bracket to move closer to or away from the first wire frame main shaft and the second wire frame main shaft. The tape roller, clamping mechanism, and cutting mechanism are all fixedly installed on the positioning bracket. Tape rolls are placed on the tape rollers. After the tape rolls are pulled out, they pass through the clamping mechanism and the cutting mechanism. A telescopic cylinder is also fixedly installed on the positioning bracket. Tape grippers are connected to the telescopic cylinder. The telescopic cylinder drives the tape grippers to move closer to or away from the pulled-out tape rolls.

[0015] Furthermore: a tape feeding machine and a second tape wrapping machine are fixedly installed on the base plate, and the tape feeding machine and the second tape wrapping machine wrap tape around the wire core of the wire feeding machine.

[0016] Furthermore: the conveyor belt includes a right-angle frame, a second lifting mechanism, a lifting plate, a conveyor belt roller, an upper clamp, a conveyor belt cutter, and a lower clamp.

The conveyor belt roller is rotatably mounted on the lifting plate. The upper clamp and the conveyor belt cutter are both fixedly installed on the lifting plate, and the lower clamp is fixedly installed on the base plate. The conveyor belt roller is equipped with a roll of conveyor belt. After the conveyor belt roll is pulled out, it passes through the upper clamp and the conveyor belt cutter. The lower clamp is located below the conveyor belt cutter.

[0017] Furthermore: The second tape machine includes a motor mounting plate, a stepper motor, a hollow shaft, and a brush assembly. The motor mounting plate is vertically arranged and fixedly installed on the base plate. The stepper motor is fixedly installed on the motor mounting plate.

The brush assembly is rotatably mounted on the right end of the hollow shaft. A tape brush is fixedly installed on the right end of the brush assembly. The tape brush presses on the wire core to rotate.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: the wire core on the main coil will be output through the wire feeding machine. Since the three-axis conveying mechanism can drive the base plate to move along the X-axis, Y-axis and Z-axis, it controls the output wire core to move to the outside of the first wire frame main shaft and the second wire frame main shaft. Then, wire frames are respectively placed on the first wire frame main shaft and the second wire frame main shaft. As the first wire frame main shaft and the second wire frame main shaft rotate, the wire core will automatically wind around the wire frames of the first wire frame main shaft and the second wire frame main shaft, thereby completing the technical effect of automatic winding.

[0035] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0036] The components of the present invention embodiments described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] like Figure 1-13 As shown, a dual-axis OBC coil winding device of the present invention includes a frame 01, and a wire feeder 02 is provided on both the left and right sides of the frame 01. Two main coils 03 are installed in the wire feeder 02.

[0041] Two first wire frame spindles 04 are fixedly installed on the frame 01. A gantry bracket 05 is fixedly installed on the frame 01. Two second wire frame spindles 06 are fixedly installed on the upper end of the gantry bracket 05. The second wire frame spindles 06 and the first wire frame spindles 04 are arranged symmetrically above and below each other.

[0042] Two three-axis conveying mechanisms 11 are fixedly installed on the frame 01. The three-axis conveying mechanism 11 drives and connects to the base plate 1. The base plate 1 is fixedly installed with the wire feeder 2. The wire cores 5 in the wire feeder 02 are wound one by one on the first wire feeder main shaft 04 and the second wire feeder main shaft 06 after passing through the wire feeder 2.

[0043] The principle is as follows: the wire core 5 on the main coil 03 will be output through the wire conveyor 2. Since the three-axis conveying mechanism 11 can drive the base plate 1 to move along the X-axis, Y-axis and Z-axis, it controls the output wire core 5 to move to the outside of the first wire frame main shaft 04 and the second wire frame main shaft 06. Then, wire frames are placed on the first wire frame main shaft 04 and the second wire frame main shaft 06 respectively. As the first wire frame main shaft 04 and the second wire frame main shaft 06 rotate, the wire core 5 will automatically wind around the wire frames of the first wire frame main shaft 04 and the second wire frame main shaft 06, thereby completing the technical effect of automatic winding.

[0044] Furthermore: The frame 01 is fixedly equipped with a feeding conveyor 07 and a discharging conveyor 08. The first wire frame main shaft 04 is located between the feeding conveyor 07 and the discharging conveyor 08. Two three-axis conveying mechanisms 11 are respectively arranged on the outside of the feeding conveyor 07 and the discharging conveyor 08. The wire frame to be wound can be placed on the feeding conveyor 07 to facilitate the conveying of the wire frame with winding. In addition, the wire frame after winding can be placed on the discharging conveyor 08 for output.

[0045] Furthermore: A feeding mechanism 3 is fixedly installed on the lower side of the right base plate 1. The feeding mechanism 3 clamps the wire frame on the feeding conveyor 07 and conveys it to the first wire frame main shaft 04 and the second wire frame main shaft 06 for feeding. A feeding mechanism 09 is fixedly installed on the lower side of the left base plate 1. The feeding mechanism 09 feeds the wire core 5 onto the first wire frame main shaft 04 and the second wire frame main shaft 06 for feeding and conveying it to the feeding conveyor 08 for output. The right base plate 1 can use the feeding mechanism 3 to clamp the wire frame to be wound on the feeding conveyor 07 and move it to the first wire frame main shaft 04 and the second wire frame main shaft 06, thus achieving the technical effect of automatic wire frame feeding.

[0046] Furthermore, the feeding mechanism 3 and the unloading mechanism 09 have the same structure, each including two displacement devices 31, two displacement plates 32, a rotating shaft 33, a rotary cylinder 34, and a gripper cylinder 7. The displacement devices 31 are fixedly installed on the lower side of the base plate 1. The displacement devices 31 drive the displacement plates 32 to move closer to or away from the first wire frame main shaft 04 and the second wire frame main shaft 06. The rotating shaft 33 is rotatably installed between the two displacement plates 32. The two gripper cylinders 7 are fixedly installed at the left and right ends of the rotating shaft 33. The rotary cylinder 34 is fixedly installed on one of the displacement plates 32. The rotary cylinder 34 drives the rotating shaft 33 to rotate. This allows the gripper cylinder 7 of the feeding mechanism 3 to rotate, which can grip the wire frame to be wound on the feeding conveyor 07. Combined with the displacement of the entire base plate 1, it realizes the automatic feeding action on the wire frame, which speeds up production efficiency and facilitates subsequent winding actions.

[0047] Furthermore: Two wire frame baffles 010 are fixedly installed on the feeding conveyor 07. The two wire frame baffles 010 are parallel to each other and set apart. The gripper cylinder 7 of the feeding mechanism 3 clamps and feeds the wire frame between the two wire frame baffles 010. It can provide a conveying limit effect for the wire frame to be wound. The gripper cylinder 7 of the feeding mechanism 3 can stably clamp the wire frame to perform the feeding action.

[0048] Furthermore: A first lifting platform 011 is fixedly installed on both the front and rear sides of the gantry bracket 05. A vertical plate 012 is connected to the first lifting platform 011. Two first tape wrapping machines 013 are fixedly installed on the vertical plate 012. The first tape wrapping machines 013 wrap tape on the two first wire frame main shafts 04 and the two second wire frame main shafts 06 after the wire core 5 has been wound. After the wire core 5 is wound on the wire frame, insulating tape can be wrapped on the outside of the winding by the first tape wrapping machines 013, thereby ensuring the production quality of the product.

[0049] Furthermore: The first tape wrapping machine 013 includes a shifting mechanism 0131, a positioning bracket 0132, a tape roller 0133, a clamping mechanism 0134, and a cutting mechanism 0135. The shifting mechanism 0131 is fixedly installed on the side plate. The shifting mechanism drives the positioning bracket 0132 to move closer to or away from the first wire frame main shaft 04 and the second wire frame main shaft 06. The tape roller 0133, the clamping mechanism 0134, and the cutting mechanism 0135 are all fixedly installed on the positioning bracket 0132. A roll of tape 10 is placed on the tape roller 0133. After the tape roll 10 is pulled out, it passes through the clamping mechanism 0134 and the cutting mechanism 0135. A telescopic cylinder 014 is also fixedly installed on the positioning bracket 0132. The telescopic cylinder 014 drives the tape roll 10 to move closer to or away from the first wire frame main shaft 04 and the second wire frame main shaft 06. With gripper 015, telescopic cylinder 014 drives the tape gripper 015 to move closer to or away from the pulled-out tape roll 10. After the tape roll 10 on the tape roller 0133 is pulled out, it passes through clamping mechanism 0134 and cutting mechanism 0135. The tape roll 10 can be gripped by tape gripper 015 and pushed out by telescopic cylinder 014. After the tape roll 10 is pulled out, it can be moved closer to the first wire frame main shaft 04 and the second wire frame main shaft 06 by shifting mechanism 0131. With the rotation of the main shaft, the tape roll 10 is wound on the winding. After the winding is completed, clamping mechanism 0134 is used to position the pulled-out tape roll 10, and then cutting mechanism 0135 is activated to cut the tape roll 10, realizing the technical effect of automatic tape wrapping.

[0050] Furthermore, a tape feeding machine 4 and a second tape wrapping machine 9 are fixedly installed on the base plate 1. The tape feeding machine 4 and the second tape wrapping machine 9 wrap tape around the wire core 5 of the wire feeding machine 2. The tape wrapping action can be performed before the wire core 5 is wound, thereby providing insulation to the outer wall of the wire core 5 and facilitating the subsequent winding action on the wire frame.

[0051] Furthermore: two wire feeding machines 2 are fixedly installed on the upper side of the base plate 1, and a feeding mechanism 3 is fixedly installed on the lower side of the base plate 1; a tape feeding machine 4 is fixedly installed on the base plate 1, and wire cores 5 are driven and connected to the wire feeding machines 2, and tape is wound onto the wire cores 5 of the wire feeding machines 4; one end of the wire feeding machine 2 is provided with a wire outlet 6, and two gripper cylinders 7 are driven and connected to the feeding mechanism 3, and the gripper cylinders 7 are respectively arranged below the wire outlet 6;

[0052] The principle is as follows: A feeding mechanism 3 is set at the bottom of the base plate 1. When the feeding mechanism 3 is working, it can realize the technical effect of automatic feeding of the wire frame. At the same time, the gripper cylinder 7 of the feeding mechanism 3 is set below the wire outlet 6, so it can facilitate the wire core 5 of the wire feeder 2 to exit next to the wire frame after the wire is exited. Subsequently, the wire frame can be rotated to achieve the technical effect of winding on the wire frame. In addition, the tape feeder 4 can wrap insulating tape on the unwound wire core 5, so it can achieve better insulation effect and improve the production efficiency and production quality of the winding.

[0053] Furthermore, the feeding mechanism 3 includes two displacement devices 31, two displacement plates 32, a rotating shaft 33, and a rotary cylinder 34. The displacement devices 31 are fixedly installed on the lower side of the base plate 1, and each displacement device 31 drives the displacement plate 32 to move left and right. The rotating shaft 33 is rotatably installed between the two displacement plates 32. Two gripper cylinders 7 are fixedly installed at the left and right ends of the rotating shaft 33, and the rotary cylinder 34 is fixedly installed on one of the displacement plates 32. The rotary cylinder 34 drives the rotating shaft 33 to rotate. This allows the gripper cylinders 7 of the feeding mechanism 3 to rotate, which can grip the wire frame to be wound on the conveyor line. In conjunction with the displacement of the entire base plate 1, it realizes the automatic feeding action on the wire frame, which speeds up production efficiency. In addition, the gripper cylinders 7 are positioned below the wire outlet 6, which also facilitates the subsequent winding action.

[0054] Furthermore, cylinder support seats 8 are fixedly installed at both ends of the rotating shaft 33, and the gripper cylinders 7 are fixedly installed on the cylinder support seats 8 one by one, with the two cylinder support seats 8 having the same angle; this makes the installation and fixing of the gripper cylinders 7 more secure and reliable, and improves their service life.

[0055] Furthermore, the displacement device 31 includes a displacement cylinder 311, an X-axis guide rail 312, and an X-axis slider 313. The X-axis guide rail 312 and the displacement cylinder 311 are both fixedly installed on the bottom of the base plate 1. The X-axis slider 313 is slidably installed on the X-axis guide rail 312. The displacement cylinder 311 drives the X-axis slider 313 to move left and right on the X-axis guide rail 312. The displacement plates 32 are fixedly installed on the X-axis slider 313 in a corresponding manner. This allows the gripper cylinder 7 to move more stably closer to or further away from the wire frame, ensuring the stability of the feeding.

[0056] Furthermore, two second tape wrapping machines 9 are fixedly installed on the base plate 1. The tape feeding machine 4 and the second tape wrapping machine 9 wrap tape around the core 5 of the conveyor line. After the tape feeding machine 4 cuts the tape, the tape will be conveyed together with the core 5 to the second tape wrapping machine 9, and the second tape wrapping machine 9 will wrap the tape around the core 5 to achieve the technical effect of automatic tape wrapping, thereby improving the production efficiency and quality of winding products.

[0057] Furthermore: The tape conveyor 4 includes a right-angle frame 41, a second lift 42, a lifting plate 43, a tape roller 44, an upper clamp 45, a tape cutter 46, and a lower clamp 47. The right-angle frame 41 is fixedly installed on the base plate 1. The second lift 42 is fixedly installed on the upper end of the right-angle frame 41. The lifting plate 43 is vertically arranged. The second lift 42 drives the lifting plate 43 to move up and down. The tape roller 44 is rotatably mounted on the lifting plate 43. The upper clamp 45 and the tape cutter 46 are both fixedly installed on the lifting plate 43. The lower clamp 47 is fixedly installed on the base plate 1. A tape roll 10 is installed on the tape roller 44. After the tape roll 10 is pulled out, it passes through the upper clamp 45 and the tape cutter 46. The lower clamp 47 is located on the tape cutter. Below 46; During operation, the tape roll 10 is pulled out and passes through the upper clamp 45 and the tape cutter 46. The second lift 42 drives the entire lifting plate 43 to descend, thereby allowing the pulled-out tape roll 10 to descend to the position of the lower clamp 47. The lower clamp 47 clamps the pulled-out tape roll 10. At this time, the second lift 42 drives the lifting plate 43 to rise, thereby achieving the technical effect of automatically pulling out the tape roll 10. When both the upper clamp 45 and the lower clamp 47 clamp the tape roll 10, the tape cutter 46 can be used to cut the pulled-out tape roll 10. Since the lower clamp 47 clamps the tape roll 10 together with the wire core 5, the cut tape roll 10 can be attached to the wire core 5, which is convenient for subsequent tape wrapping operations.

[0058] Furthermore: The second tape wrapping machine 9 includes a motor mounting plate 91, a stepper motor 92, a hollow shaft 93, and a brush assembly 94. The motor mounting plate 91 is vertically arranged and fixedly mounted on the base plate 1. The stepper motor 92 is fixedly mounted on the motor mounting plate 91. The hollow shaft 93 is rotatably mounted on the motor mounting plate 91. The stepper motor 92 drives the hollow shaft 93 to rotate. The wire core 5 passes through the hollow shaft 93. The brush assembly 94 is rotatably mounted on the right end of the hollow shaft 93. A tape brush is fixedly installed on the right end of 4. The tape brush presses on the wire core 5 and rotates. The wire core 5 can be conveyed inside the hollow shaft 93. The stepper motor 92 drives the hollow shaft 93 to rotate, thereby driving the brush assembly 94 to press on the wire core 5. Since the wire core 5 is conveyed to the inside of the brush assembly 94 together with the tape roll 10, the rotating brush assembly 94 can stably stick and wrap the tape roll 10 on the wire core 5, thereby achieving the technical effect of automatic tape wrapping.

[0059] Furthermore, a three-axis conveying mechanism 11 is provided on the bottom side of the base plate 1. The three-axis conveying mechanism 11 drives the base plate 1 to translate along the three directions of X-axis, Y-axis and Z-axis; so that the entire base plate 1 can translate along the three directions, thereby matching the feeding mechanism 3 to achieve the effect of automatic feeding of the wire frame, effectively improving production efficiency.

[0060] Furthermore, the three-axis conveying mechanism 11 includes an X-axis conveying mechanism 111, a Y-axis conveying mechanism 112, and a Z-axis conveying mechanism 113. The Y-axis conveying mechanism 112 is fixedly installed on the frame 01. The Y-axis conveying mechanism 112 drives the Z-axis conveying mechanism 113 to move back and forth along the Y-axis direction. The Z-axis conveying mechanism 113 drives the X-axis conveying mechanism 111 to move up and down along the Z-axis direction. The X-axis conveying mechanism 111 drives the base plate 1 to move left and right along the X-axis direction, making the translational movement of the base plate 1 along the X-axis, Y-axis, and Z-axis directions more stable.

[0061] Furthermore, a cutting mechanism 12 is provided above the outlet 6. The cutting mechanism 12 includes a lifting cylinder 121 and a pneumatic scissors 122. The lifting cylinder 121 is fixedly installed on the base plate 1. The lifting cylinder 121 drives the pneumatic scissors 122 to move closer to or away from the outlet 6. The pneumatic scissors 122 cuts the wire core 5 at the outlet 6. After the wire group is wound on the wire frame, the lifting cylinder 121 can be used to bring the pneumatic scissors 122 closer to the wire core 5 at the outlet 6. At this time, the pneumatic scissors 122 is activated to achieve the technical effect of cutting the wire core 5, thereby completing the automatic winding of the wire group and accelerating the production efficiency.

[0062] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
