Description

Technical Field

[0001] This invention belongs to the field of inductor coil winding equipment, and particularly relates to a production equipment for a vehicle-mounted OBC inductor coil double-head bidirectional connection machine. Background Technology

[0002] The on-board charger (OBC) is a core component in new energy vehicles that converts alternating current (AC) to direct current (DC) to charge the power battery. The inductor coil within the OBC is a critical component, and its winding quality and efficiency directly affect the overall performance and manufacturing cost of the OBC.

[0003] Currently, existing inductor winding equipment has many shortcomings when winding bidirectional continuous coils. Traditional winding methods cannot achieve fully automated coil winding. Typically, the first coil needs to be wound manually, and then the wire is pulled out to a certain length before the other side of the coil is wound on another machine. This production method is not only inconvenient to operate, but also requires multiple workers, resulting in low production efficiency and high labor costs. Furthermore, manual operation makes it difficult to ensure the consistency and stability of coil winding, easily generating defective products and affecting product quality.

[0004] Therefore, there is an urgent need for a production equipment that can achieve fully automated double-head bidirectional winding in order to improve production efficiency, reduce labor costs, and ensure product quality. Summary of the Invention

[0005] The purpose of this invention is to overcome the problems existing in the above-mentioned background art and to provide a production equipment for a vehicle-mounted OBC inductor coil double-head bidirectional connection machine.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A production equipment for a vehicle-mounted OBC inductor coil dual-head bidirectional wiring machine includes:

[0008] frame;

[0009] A wire-forming mechanism, mounted on the frame, is used to form wires.

[0010] A wire feeding mechanism, mounted on the frame, is used to feed wires;

[0011] A wire pressing mechanism, mounted on the frame, is used to press the wire during coil winding to prevent it from slipping.

[0012] A lifting mechanism is mounted on the frame and connected to the wire feeding mechanism and the wire assembling mechanism, used to drive the wire feeding mechanism and the wire assembling mechanism to move up and down;

[0013] The first winding head and the second winding head are respectively disposed on the frame and arranged at intervals. The first winding head is used to wind a coil in a first direction, and the second winding head is used to wind a coil in a second direction opposite to the first direction.

[0014] A core-pulling mechanism, mounted on the frame, is used to press the wire during winding to ensure the height of the coil;

[0015] A wire-cutting mechanism is mounted on the frame and located on one side of the first winding head and the second winding head, and is used to cut the wound product.

[0016] The controller, mounted on the frame, is electrically connected to the wire feeding mechanism, the wire pressing mechanism, the lifting mechanism, the first winding head, the second winding head, the core pulling mechanism, and the wire cutting mechanism, and is used to control the operating parameters of each mechanism.

[0017] Furthermore, the wire feeding mechanism and the wire assembling mechanism have a first position and a second position under the drive of the lifting mechanism. In the first position, the wire feeding mechanism and the wire assembling mechanism correspond to the first winding head or the second winding head. In the second position, the wire feeding mechanism and the wire assembling mechanism avoid the mold pin.

[0018] Furthermore, the coil wound by the first winding head is a forward coil, and the coil wound by the second winding head is a reverse coil. The first winding head and the second winding head sequentially wind the same wire to form a bidirectional continuous winding coil.

[0019] Furthermore, it also includes an assembly line mechanism, which is mounted on the frame and located downstream of the wire cutting mechanism, for conveying the wound products.

[0020] Furthermore, the core-pulling mechanism is also provided with a mold pin, which cooperates with the first winding head and the second winding head to limit the winding position of the wire.

[0021] Furthermore, the controller is a PLC controller.

[0022] The beneficial effects of this invention are:

[0023] By setting up two winding heads, the first winding head and the second winding head, and coordinating the lifting mechanism to drive the wire feeding mechanism and the wire forming mechanism to switch between the two winding heads, continuous bidirectional automatic winding of the same wire is achieved, eliminating the need for manual transfer of wire between different devices and greatly improving production efficiency.

[0024] By setting up a wire pressing mechanism and a core pulling mechanism, the wire is pressed during the winding process, which ensures that the coil height is consistent, the coil winding quality is stable, and the scrap rate is reduced.

[0025] It has achieved fully automated production, reduced manual operation, lowered labor costs, and improved equipment safety and market competitiveness. Attached Figure Description

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0038] Example 1

[0039] like Figures 1-6 As shown, this embodiment of the invention provides a production equipment for a dual-head bidirectional wiring machine for vehicle-mounted OBC inductor coils, including a frame 1, a winding mechanism 2, a wire feeding mechanism 3, a wire pressing mechanism 4, a lifting mechanism 5, a first winding head 6, a second winding head 7, a core pulling mechanism 8, a wire cutting mechanism 9, a controller 10, and a production line mechanism 12.

[0040] like Figure 1 As shown, frame 1 is the basic load-bearing structure of this equipment. It has an overall rectangular frame structure, which is constructed by welding or bolting metal profiles, and has sufficient structural strength and stability. The upper surface of frame 1 is a working platform for installing various functional mechanisms.

[0041] The wire straightening mechanism 2 is mounted on the frame 1 and located at one end of the frame 1. The wire straightening mechanism 2 includes multiple straightening rollers and a straightening plate. The straightening rollers are arranged in a straight line, and the wire passes sequentially between the rollers. Through the guiding and squeezing action of the rollers, bending and twisting of the wire are eliminated, keeping the wire straight for subsequent processes. The specific structure of the wire straightening mechanism 2 is conventional technology in this field and will not be described in detail here.

[0042] The wire feeding mechanism 3 is mounted on the frame 1 and located downstream of the wire feeding mechanism 2. The wire feeding mechanism 3 includes a wire feeding motor and a wire feeding wheel assembly. The wire feeding motor drives the wire feeding wheel assembly to rotate, and the wire is fed forward through the friction between the wire feeding wheel assembly and the wire. The wire feeding mechanism 3 is electrically connected to the controller 10, which controls the rotation speed and rotation time of the wire feeding motor, thereby controlling the wire feeding speed and wire feeding length.

[0043] The wire pressing mechanism 4 is mounted on the frame 1, downstream of the wire feeding mechanism 3. The wire pressing mechanism 4 includes a wire pressing cylinder and a wire pressing block, with the piston rod of the cylinder connected to the block. When the winding head is winding, the controller 10 controls the wire pressing cylinder to move downwards and press the wire, preventing slippage during winding and ensuring stability and accuracy. After winding is complete, the cylinder resets, and the block releases the wire.

[0044] The lifting mechanism 5 is mounted on the frame 1 and connected to the wire feeding mechanism 3 and the wire assembling mechanism 2. The lifting mechanism 5 includes a lifting cylinder and a lifting guide rail. The cylinder body of the lifting cylinder is fixed to the frame 1, and the piston rod is fixedly connected to the connecting plate of the wire feeding mechanism 3 and the wire assembling mechanism 2. The lifting guide rail is vertically mounted on the frame 1, and the connecting plate slides along the lifting guide rail. Driven by the lifting cylinder, the connecting plate drives the wire feeding mechanism 3 and the wire assembling mechanism 2 to move up and down along the lifting guide rail. The lifting mechanism 5 is electrically connected to the controller 10, which controls the extension and retraction of the lifting cylinder, thereby enabling the wire feeding mechanism 3 and the wire assembling mechanism 2 to switch between a first position and a second position. In the first position, the wire feeding mechanism 3 and the wire assembling mechanism 2 correspond to either the first winding head 6 or the second winding head 7, allowing the wire to enter the winding head for winding. In the second position, the wire feeding mechanism 3 and the wire assembling mechanism 2 move upwards to avoid the mold pin 11, facilitating the movement of the wire feeding mechanism 3 between the two winding heads.

[0045] The first winding head 6 and the second winding head 7 are respectively mounted on the frame 1 and arranged at intervals. The two winding heads have identical structures, each including a winding spindle, a winding die, and a drive motor. The winding spindle is rotatably mounted on the frame 1, the winding die is fixed to the end of the winding spindle, and the drive motor is connected to the winding spindle via a transmission mechanism to drive the winding spindle to rotate. The first winding head 6 is used to wind coils in a first direction (e.g., forward coils), and the second winding head 7 is used to wind coils in a second direction opposite to the first direction (e.g., reverse coils). Both winding heads are electrically connected to a controller 10, which controls the start / stop and rotation parameters of the two winding heads. The first winding head 6 and the second winding head 7 sequentially wind the same wire, thereby forming a bidirectional continuous winding coil.

[0046] The core-pulling mechanism 8 is mounted on the frame 1, located beside the first winding head 6 and the second winding head 7. The core-pulling mechanism 8 includes a core-pulling cylinder and a core-pulling rod. The cylinder body of the core-pulling cylinder is fixed to the frame 1, and the piston rod is connected to the core-pulling rod. A mold pin 11 is provided at the end of the core-pulling rod. The mold pin 11 cooperates with the winding molds of the first winding head 6 and the second winding head 7 to limit the winding position of the wire. During winding, the controller 10 controls the core-pulling cylinder to actuate, driving the core-pulling rod to insert the mold pin 11 into the winding mold, compressing the wire and ensuring that the coil height does not exceed the set value. After winding is completed, the core-pulling cylinder resets, and the mold pin 11 exits the winding mold.

[0047] The wire cutting mechanism 9 is mounted on the frame 1 and located on one side of the first winding head 6 and the second winding head 7. The wire cutting mechanism 9 includes a wire cutting cylinder and a shear assembly. The cylinder body of the wire cutting cylinder is fixed to the frame 1, and the piston rod is connected to the shear assembly. The shear assembly includes a fixed blade and a movable blade. The movable blade moves relative to the fixed blade under the drive of the wire cutting cylinder, thereby cutting the wire. The wire cutting mechanism 9 is electrically connected to a controller 10, which controls the timing of the wire cutting cylinder's operation. After the bidirectional winding coil is completed, the controller 10 controls the wire cutting mechanism 9 to cut the wire, thus completing the winding of one product.

[0048] The assembly line mechanism 12 is mounted on the frame 1 and located downstream of the wire-cutting mechanism 9. The assembly line mechanism 12 includes a conveyor belt and a conveyor motor. The conveyor belt rotates under the drive of the conveyor motor, transporting the products cut by the wire-cutting mechanism 9 to the next workstation or collection area. The assembly line mechanism 12 is electrically connected to a controller 10, which controls the start, stop, and speed of the conveyor motor.

[0049] The controller 10 is mounted on the frame 1 and is electrically connected to the wire feeding mechanism 3, the wire pressing mechanism 4, the lifting mechanism 5, the first winding head 6, the second winding head 7, the core pulling mechanism 8, the wire cutting mechanism 9, and the assembly line mechanism 12. The controller 10 is a PLC controller, which stores a control program to control the operating parameters and action sequence of each mechanism to achieve a fully automatic winding process.

[0050] Working principle

[0051] The working principle of the production equipment for the vehicle-mounted OBC inductor coil dual-head bidirectional wiring machine of the present invention is as follows:

[0052] First, turn on the power to the equipment and install the spool on the wire feeding frame. Pull the wire out of the spool and pass it through the wire straightening mechanism 2, the wire feeding mechanism 3, and the wire pressing mechanism 4 in sequence. The wire straightening mechanism 2 straightens the wire, eliminating bending and twisting, and keeping the wire straight.

[0053] The parameters of the coil to be wound, including the number of turns, winding speed, and wire feeding length, are adjusted using the controller 10. After starting the equipment, the wire feeding mechanism 3 conveys the wire forward to the first winding head 6.

[0054] The first winding head 6 winds the wire into a coil in the first direction (e.g., a forward coil). During the winding process, the core-pulling mechanism 8 is activated, and the mold pin 11 is inserted into the winding mold to press the wire, ensuring that the coil height does not exceed the set value; the wire-pressing mechanism 4 is activated to press the wire to prevent it from slipping during winding.

[0055] Once the first forward coil is wound, the first winding head 6 stops rotating and the mold opens. The lifting mechanism 5 activates, driving the wire feeding mechanism 3 and the wire assembling mechanism 2 to move upwards to avoid the mold pin 11. The wire feeding mechanism 3 continues to feed the wire, moving it from the position of the first winding head 6 to the position of the second winding head 7.

[0056] When the wire reaches the second winding head 7, the lifting mechanism 5 activates again, driving the wire feeding mechanism 3 and the wire assembling mechanism 2 downwards until the wire enters the mold pin 11 position of the second winding head 7. Subsequently, the second winding head 7 begins winding the coil, with the coil direction opposite to that of the first winding head 6 (e.g., a reverse coil). During winding, the core-pulling mechanism 8 and the wire-pressing mechanism 4 activate again, pressing the wire to ensure the coil height and prevent wire slippage.

[0057] After the second coil is wound, the wire feeding mechanism 3 delivers the product to the wire cutting mechanism 9. The wire cutting mechanism 9 cuts the wire, thus completing the winding of a bidirectional continuous coil product. The cut product falls into the assembly line mechanism 12, which transports it to the next workstation or collection area.

[0058] The above process is repeated cyclically to achieve fully automated continuous production of the dual-head bidirectional wired product for vehicle-mounted OBC inductor coils.

[0059] Example 2

[0060] The difference between this embodiment and Embodiment 1 is that the wire feeding mechanism 3 and the wire assembling mechanism 2 have a first position and a second position under the drive of the lifting mechanism 5. In the first position, the wire feeding mechanism 3 and the wire assembling mechanism 2 correspond to the first winding head 6 or the second winding head 7. At this time, the axis of the wire is aligned with the axis of the winding mold of the winding head, and the wire can smoothly enter the winding mold for winding. In the second position, the wire feeding mechanism 3 and the wire assembling mechanism 2 move upward, and their height is higher than the upper end face of the mold pin 11, thereby avoiding the mold pin 11. This allows the wire feeding mechanism 3 to move freely between the two winding heads without being interfered with by the mold pin 11.

[0061] Example 3

[0062] The difference between this embodiment and Embodiment 1 is that the mold pin 11 on the core-pulling mechanism 8 is a replaceable structure, with different specifications of mold pin 11 corresponding to different specifications of coil products. When it is necessary to produce coils of different specifications, only the corresponding mold pin 11 needs to be replaced, and the corresponding winding parameters need to be adjusted in the controller 10. There is no need to replace the entire set of equipment, which enhances the versatility and adaptability of the equipment.

[0063] Example 4

[0064] The difference between this embodiment and embodiment one is that the controller 10 can also be connected to a touch screen display. Operators can input winding parameters through the touch screen display and view the operating status and winding data of the equipment in real time, which is convenient for operation and monitoring.

[0065] Example 5

[0066] The difference between this embodiment and Embodiment 1 is that a tension adjustment device is also provided between the wire forming mechanism 2 and the wire feeding mechanism 3. The tension adjustment device is used to adjust the tension of the wire during the conveying process to ensure the stability of the wire conveying and the winding quality.

[0067] The above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also fall within the scope of the present invention, and the patent protection scope of the present invention should be defined by the claims.
