Description

Technical Field

[0001] The present application belongs to the technical field of motor processing equipment, and more specifically, relates to a multi-station motor winding equipment. Background Art

[0002] A motor is a common power device, typically consisting of a stator and a rotor. Its primary operating principle is to use an energized coil to generate a rotating magnetic field, which acts on the rotor to create a magneto-electric torque, thereby driving an external mechanism. Common motors have coils wound around the stator or rotor. Currently, winding machines are commonly used in motor production to wind the stator or rotor.

[0003] During the winding process, the winding machine often needs to drive the winding head to rise and fall or move left and right according to the processing design requirements; and for some processing scenarios, in addition to driving the winding head to rise and fall or move left and right, it is often necessary to drive the winding head to move diagonally. However, on existing winding machines, the mechanisms that drive the winding head to rise and fall and move left and right are usually two independent modules, that is, one module drives the winding head to rise and fall, and the other module drives the winding head to move left and right. This means that when it is necessary to drive the winding head to move diagonally, the left and right moving modules and the lifting and moving modules must be controlled to work simultaneously and cooperate with each other. This not only places high demands on the control accuracy of the equipment, but also the two independent drive modules make the mechanical structure of the entire equipment more complicated, resulting in an increase in the overall production cost of the equipment.

[0026] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0027] like Figure 1-7 As shown, a multi-station motor winding equipment includes a machine 1 and a controller. The machine 1 is provided with a wire feeding mechanism, a winding mechanism, a product fixture 2 and a wire breaking mechanism respectively connected to the controller. The wire feeding mechanism is used to place the wire roll and convey the wire bundle to the winding mechanism; the product fixture 2 is used to install the product to be wound, so as to prevent the product from moving during winding; the winding mechanism is used to wind the wire bundle conveyed by the wire feeding mechanism into the product on the product fixture 2; the wire breaking mechanism is used to pull the wire bundle between the winding mechanism and the product fixture 2 after the winding is completed, so as to facilitate the replacement of the product on the product fixture 2. During operation, the operator places the entire roll of wire harness on the wire feeding mechanism, and at the same time fixes the product to the product fixture 2, and then controls the wire feeding mechanism and the winding mechanism respectively through the controller, and the winding mechanism winds the wire harness into the product on the product fixture 2; when the winding of the product on the product fixture 2 is completed, the wire breaking mechanism is controlled to work, and the wire breaking mechanism pulls the wire harness between the winding mechanism and the product fixture 2 to complete the winding, after which the operator can remove the wound product from the product fixture 2.

[0028] The winding mechanism includes a mounting frame and a front and rear driving mechanism for driving the mounting frame to move forward and backward. The mounting frame is slidably connected to the machine 1. A winding head and a winding positioning mechanism are provided on the mounting frame. The winding positioning mechanism is connected to the winding head and is used to drive the winding head to move freely in two dimensions on the mounting frame, including left and right movement, lifting movement and oblique movement.

[0029] Specifically, the mounting frame includes a front and rear movable frame 3, a transverse movable frame 4 and a lifting movable frame 5. The front and rear movable frame 3 is slidably connected to the machine platform 1, and the front and rear movable frame 3 can slide forward and backward on the machine platform 1; the transverse movable frame 4 is slidably connected to the front and rear movable frame 3, and the transverse movable frame 4 can slide left and right on the front and rear movable frame 3; the lifting movable frame 5 is slidably connected to the transverse movable frame 4, and the lifting movable frame 5 can be lifted and moved on the transverse movable frame 4. The winding movement mechanism includes two movement motors 6 and a transmission belt 7. The two movement motors 6 are respectively fixedly mounted on the front and rear moving frames 3, and the two movement motors 6 are symmetrically arranged with the mid-vertical line of the front and rear moving frames 3. The winding head is fixedly mounted on the lifting and moving frame 5; four first guide wheels 8 are installed on the transverse moving frame 4, and a second guide wheel 9 is installed at the lower end of the lifting and moving frame 5. The two ends of the transmission belt 7 are respectively fixedly connected to the end of the lifting and moving frame 5 away from the second guide wheel 9, and the transmission belt 7 is respectively sleeved on the first guide wheel 8, the output shaft of the two movement motors 6 and the second guide wheel 9, so that when the two movement motors 6 are working, they can pull the transmission belt 7 to move, thereby realizing the driving of the winding head to move freely in two dimensions on the mounting frame.

[0030] When it is necessary to drive the winding head to move left and right, by controlling the two travel motors 6 to rotate at the same speed and in the same direction, the transmission belt 7 will be subjected to force to drive the first guide wheel 8 to move, and the first guide wheel 8 will pull the horizontal moving frame 4 to move left and right on the front and rear moving frames 3, and the lifting moving frame 5 and the winding head will move synchronously with the horizontal moving frame 4.

[0031] When the winding head needs to be driven to move up and down, the two travel motors 6 are controlled to rotate in opposite directions at the same speed, and the travel motor 6 pulls the transmission belt 7, thereby pulling the winding head up and down on the mounting frame, and the winding head moves synchronously with the lifting frame 5.

[0032] When it is necessary to drive the winding head to move obliquely, the two travel motors 6 can be controlled to rotate at different speeds according to actual requirements. The travel motor 6 pulls the transmission belt 7 during rotation, and then pulls or pushes the lifting and moving frame 5 to simultaneously lift and move left and right, so that the winding head moves obliquely.

[0033] It should be noted that when the winding head is driven to move horizontally, the first guide wheel 8 drives the horizontal moving frame 4 to move, and then drives the lifting moving frame 5 and the winding head to move; when the winding head is driven to move up and down, the first guide wheel 8 can remain stationary, and the lifting moving frame 5 is driven to move up and down through the transmission belt 7, and then drives the winding head to move up and down.

[0034] In this example, the four first guide wheels 8 are distributed in a rectangular shape on the transverse moving frame 4, so that after the transmission belt 7 is installed, the entire belt 7 is in a "cross" shape, thereby being able to achieve smooth driving of the winding head movement.

[0035] The front-to-back drive mechanism is used to drive the winding head to move forward and backward. On the one hand, it is convenient for loading and unloading products on the product fixture 2, and on the other hand, it is also convenient for tearing off the wire harness after the winding is completed. Specifically, the front-to-back drive mechanism includes a front-to-back drive motor 10 and a front-to-back drive screw 11. The front-to-back drive motor 10 is fixedly mounted on the machine 1. The output end of the front-to-back drive motor 10 is connected to the front-to-back drive screw 11. The front-to-back movable frame 3 is provided with a front-to-back movable sleeve 12, and the front-to-back movable sleeve 12 is slidably connected to the front-to-back drive screw 11. During operation, the front-to-back drive screw 11 is driven to rotate by the front-to-back drive motor 10, thereby driving the front-to-back movable sleeve 12 to slide on the front-to-back drive screw 11, pulling the front-to-back movable frame 3 to move forward and backward, and the horizontal movable frame 4, the lifting movable frame 5 and the winding head move synchronously with the front-to-back movable frame 3.

[0036] To limit and guide the running direction of the front-to-back movable frame 3, two parallel front-to-back sliding guide rails 13 are provided on the machine platform 1. A front-to-back movable slider 14 is fixedly mounted on the front-to-back movable frame 3, and the front-to-back movable slider 14 is slidably engaged with the front-to-back sliding guide rails 13. During operation, the front-to-back drive motor 10 rotates the front-to-back drive screw 11, causing the front-to-back movable sleeve 12 to slide on the front-to-back drive screw 11, thereby driving the front-to-back movable frame 3 to slide on the front-to-back sliding guide rails 13.

[0037] The winding head includes a rocker arm 15, hinged at both ends to the lifting and moving frame 5. The rocker arm 15 can tilt around the hinge point. Six winding rods 16 are fixedly mounted on the rocker arm 15, equidistantly spaced on the rocker arm 15, allowing the winding mechanism to simultaneously wind six products. Each winding rod 16 is equipped with a wire groove 161 and a winding needle 17, and each winding needle 17 on the winding rod 16 is connected to the corresponding wire groove 161. During operation, the wire harness passes through the wire groove 161 and is passed to the winding needle 17. By driving the winding needle 17 along a predetermined trajectory, the product on the product fixture 2 can be wound.

[0038] The lifting frame 5 is provided with a wire hanging mechanism, which is connected to the rocker 15 and is used to drive the winding needle 17 to rotate, thereby allowing the winding needle 17 to hang the wire harness on the product on the product fixture 2, thereby facilitating subsequent winding operations. Specifically, the wire hanging mechanism includes a wire hanging cylinder 18 and a push rod 19. The wire hanging cylinder 18 is hinged to the lifting frame 5. The output end of the wire hanging cylinder 18 is hinged to one end of the push rod 19, and the other end of the push rod 19 is fixedly connected to the rocker 15. The wire hanging cylinder 18 can drive the rocker 15 to rotate on the lifting frame 5. During the specific work, the operator passes the wire harness onto the winding needle 17, and then drives the winding needle 17 to move through the movement motor 6 to hang the wire harness on the product on the product fixture 2; after the hanging is completed, the hanging cylinder 18 is controlled to work, pushing the push rod 19 to rotate, and the push rod 19 drives the rocker arm 15 to flip on the lifting and moving frame 5, and the winding needle 17 is upright, and then the subsequent winding operation is carried out.

[0039] The machine 1 is provided with a wire breaking mechanism, which is used to break the wire harness between the winding head and the product fixture 2 after winding is completed, thereby facilitating the replacement of the product on the product fixture 2. Specifically, the wire breaking mechanism includes two wire breaking cylinders 20 and a wire clamping mounting plate 21. The two wire breaking cylinders 20 are respectively fixedly connected to the machine 1, and the output ends of the two wire breaking cylinders 20 are respectively fixedly connected to the two ends of the wire clamping mounting plate 21. The wire clamping mounting plate 21 is provided with six wire clamping cylinders 22, and the six wire clamping cylinders 22 are provided in a one-to-one correspondence with the six product fixtures 2. During operation, after the product winding of the product fixture 2 is completed, the front and rear drive motors 10 work, driving the front and rear movable frames 3 to slide backward, so that the winding needle 17 retreats to the corresponding position of the wire clamping cylinder 22, and the wire clamping cylinder 22 works to clamp the wire harness between the winding needle 17 and the product fixture 2, and then controls the wire breaking cylinder 20 to work, driving the wire clamping mounting plate 21 and the wire clamping cylinder 22 to move backward; because the wire harness is clamped by the wire clamping cylinder 22, the wire clamping cylinder 22 can pull the wire harness between the winding head and the product fixture 2 during the process of moving the wire clamping cylinder 22 backward, thereby achieving the purpose of breaking the wire.

[0040] In order to limit and guide the movement of the wire clamping mounting plate 21 and thus ensure smooth operation during the wire breaking process, in this example, two wire breaking guide rails 23 are arranged in parallel on the machine 1. Wire breaking sliders 24 are respectively provided at positions corresponding to the wire breaking guide rails 23 on the wire clamping mounting plate 21. The wire breaking sliders 24 slide and engage with the corresponding wire breaking guide rails 23. During the wire breaking process, the wire breaking cylinder 20 drives the wire clamping mounting plate 21 to slide on the wire breaking guide rails 23, thereby preventing the occurrence of displacement.

[0041] When the multi-station motor winding equipment is performing winding processing, the product on the product fixture 2 needs to be rotated to ensure that the winding needle 17 can complete the winding of the product on the product fixture 2; therefore, in this example, a product driving mechanism is provided on the machine 1, which is connected to the product fixture 2 and is used to drive the product fixture 2 to rotate in place on the machine 1. Specifically, the product driving mechanism includes a winding rotary motor 25, which is fixedly mounted on the machine 1. The output end of the winding rotary motor 25 is connected to the six product fixtures 2 via a synchronous belt, so that one winding rotary motor 25 can drive the six product fixtures 2 to rotate, thereby achieving simultaneous winding operations on six products and improving processing efficiency.

[0042] The wire feeding mechanism includes six wire feeding boxes 26 fixedly mounted on the machine 1. Each wire feeding box 26 corresponds to the position of a product fixture 2, that is, one wire feeding box 26 corresponds to one product fixture 2. Each wire feeding box 26 is equipped with a tensioning pulley 27 and a wire feeding pulley 28. The wire feeding pulley 28 is rotatably connected to the wire feeding box 26. The wire feeding pulley 28 is used to hang the entire roll of wire harness and tighten the wire harness through the tensioning pulley 27 to prevent the wire harness from loosening and ensure the stability of the wire supply. Before operation, the operator hangs the entire roll of wire harness on the wire feeding pulley 28, stretches the wire harness onto the corresponding tensioning pulley 27, then pulls it onto the wire trough 161 and finally threads it onto the winding needle 17. During operation, the end of the wire harness is first hung on the product in the product fixture 2. Then, by driving the product to rotate and driving the winding needle 17 to move along a preset trajectory, the wire harness is wound around the product in the product fixture 2.

[0043] To improve the stability of the wire harness during transport, a wire management mechanism is installed on the mounting frame. This mechanism is used to straighten and pull the wire harness onto the winding rod 16. Specifically, the wire management mechanism includes a wire management frame 29, which is fixed to the transverse movable frame 4 via screws. Six wire pulleys 30 are installed on the wire management frame 29, each corresponding to a winding needle 17. Each wire pulley 30 is rotatably connected to the wire management frame 29. Before operation, the entire wire harness is mounted on the wire feed pulley 28 and then stretched through the tensioning pulley 27. The wire harness is then stretched and laid onto the wire pulleys 30, pulled into the wire channel 161, and finally threaded onto the winding needle 17. During operation, the winding needle 17 wraps the wire harness around the product, pulling the harness and causing the wire pulleys 30 to rotate in place. The wire pulleys 30 ensure a stable supply of wire harness to the winding needle 17, preventing the harness from shifting, and ensuring the stability of the winding operation.

[0044] The outer sleeve of the winding mechanism is provided with a protective cover 31, which is fixedly connected to the machine 1. The protective cover 31 is provided with a safety door 32, which is openably connected to the protective cover 31. The arrangement between the protective cover 31 and the safety door 32 can prevent the operator from accidentally entering the equipment during processing, thereby ensuring the operator's personal safety. The opening and closing connection between the safety door 32 and the protective cover 31 is to facilitate opening the safety door 32 for maintenance or adjustment of the equipment. The side of the protective cover 31 near the product fixture 2 is a hollow surface to facilitate the operator's loading and unloading of products. The left and right side walls of the protective cover 31 are respectively provided with protective gratings 33, which are connected to the controller. During operation, if an object passes through the protective grating 33, the controller will immediately control the equipment to suspend operation. The provision of the protective grating 33 can prevent the operator from accidentally extending his hands or other parts of his body into the equipment during processing, thereby ensuring the operator's personal safety.

[0045] A warning light 34 is located at the top of the protective cover 31 and is connected to the controller. When the wire harness on one of the wire feed reels 28 runs out or the device malfunctions, the warning light 34 automatically illuminates, alerting the operator to replace the harness or debug the device. Machine 1 is equipped with control buttons 35 and a display screen 36, both of which are connected to the controller. The control buttons 35 are used to control the device's operation, including a start button, pause button, and reset button. The display screen 36 displays the device's operating parameters and status, and can also be used to debug the device's operating parameters.

[0046] Working principle:

[0047] Before the motor drives the dual-degree-of-freedom winding mechanism to work, the operator first installs the products on the six product fixtures 2 respectively, and hangs the entire roll of wire harness on the six wire feeding wheels 28 in turn, and then stretches the end of the wire harness through the corresponding tensioning wheel 27, and then stretches and lays the wire harness on the wire passing wheel 30, and then pulls it to the wire passing groove 161 and finally passes it through the winding needle 17, so that the wire harness is tightened on the wire passing wheel 30 and the winding needle 17.

[0048] Afterwards, the working parameters of the equipment are debugged through the display screen 36, and then the operation of the equipment is controlled by the control button 35; during operation, the front and rear drive motors 10 work to drive the front and rear movable frames 3 to move forward, driving the winding needle 17 to move to the corresponding position with the product fixture 2, and the winding needle 17 hangs the wiring harness on the product on the product fixture 2, so that one end of the wiring harness is fixed on the product; then the wire hanging cylinder 18 is controlled to work, and the wire hanging cylinder 18 pushes the push rod 19 to rotate, and the push rod 19 drives the rocker arm 15 to flip on the lifting and movable frame 5, and makes the winding needle 17 upright; after the wire hanging is completed, the winding rotating motor 25 and the moving motor 6 are controlled to work respectively, and the moving motor 6 drives the winding needle 17 to move freely in two dimensions according to the preset program, including lifting movement, left and right movement and oblique movement, and the winding rotating motor 25 drives the product fixture 2 to drive the product to rotate in place, completing the winding process.

[0049] After the winding is completed, the front and rear drive motors 10 work to drive the front and rear movable frames 3 to move forward, driving the winding needle 17 to move to the corresponding position of the wire clamping cylinder 22, and controlling the wire clamping cylinder 22 to work. The wire clamping cylinder 22 works to clamp the wire harness between the winding needle 17 and the product fixture 2, and then controls the wire breaking cylinder 20 to work, driving the wire clamping mounting plate 21 and the wire clamping cylinder 22 to move backward on the wire breaking guide rail 23; because the wire harness is clamped by the wire clamping cylinder 22, the wire clamping cylinder 22 can pull the wire harness between the winding head and the product fixture 2 during the backward movement of the wire clamping cylinder 22, thereby achieving the purpose of wire breaking, and then the operator removes the wound product from the product fixture 2.

[0050] The motor-driven dual-degree-of-freedom winding mechanism drives the transmission belt 7 to move through two travel motors 6, thereby driving the winding head to move freely in two dimensions on the mounting frame; it simplifies the mechanical structure, reduces the production cost, and also improves the control accuracy and processing efficiency.
