Description

Technical Field

[0001] The invention relates to the technical field of mechanical winding and automatic control, and in particular to an automatic winding machine for internal coils of track building blocks. Background Art

[0002] In the traditional coil winding machine, the rotation of the rocker can be converted into the rotation of the coil track to be wound by combining the gear set, so as to achieve the purpose of manual winding. When the size of the coil track to be wound is determined, the traditional manual winding machine can drive the coil track to be wound through the gear set. However, this design has the following problems and disadvantages:

[0003] 1. The traditional manual winding machine can perform basic winding movements, but the coil diameter needs to match the straight enameled wire stroke. Sometimes it is difficult to make each turn of the coil close together, and the need to manually press the coil greatly increases the difficulty of operation for the user;

[0004] 2. The traditional coil winding machine winds different coil tracks and places them in different positions. It is necessary to readjust the position of the limiting ring. The position of the limiting ring that can achieve simple winding is unique, and the position needs to be adjusted during winding;

[0005] 3. When performing cross-winding operations, traditional coil winding machines need to manually pull the enameled wire to the corresponding position, which affects work efficiency;

[0006] The simple electric-controlled winding machine that uses a motor instead of a rocker has the following problems and disadvantages: 1. Since the simple electric-controlled winding machine has no manual auxiliary pressing, it cannot solve the problem of each turn of the coil not being close together due to the mismatch between the coil diameter and the enameled wire stroke, which greatly reduces the attraction of the building block track to the iron ball and affects the subsequent winding; 2. The simple electric-controlled winding machine cannot perform cross-winding operations. 3. The simple electric-controlled winding machine cannot switch between forward and reverse rotation as needed during operation. In the absence of a processor, the position of the limit ring still needs to be manually adjusted, and the demand for fully automatic winding cannot be met. For this reason, we propose an automatic winding machine for the internal coils of track building blocks. Summary of the invention

[0007] In view of the above problems, the present invention provides an automatic winding machine for the internal coils of track building blocks, which can effectively improve the efficiency of batch winding, can wind different coil shapes, and effectively improve the diversity and adaptability of the product.

[0008] To this end, the present invention adopts the following technical scheme: an automatic winding machine for the internal coil of a track building block, including a wire feeding tension system and a track motion system, characterized in that it also includes a synchronous control system and a shape limiting system, the synchronous control system includes a second servo motor, a first slide and a screw platform carrying the wire feeding tension system, the synchronous control system receives input instructions from a processor to achieve matching of the coil diameter with the straight enameled wire stroke; the shape limiting system includes a steering gear and a shape selection rod arranged on the second slide, and the second slide is vertically arranged; the first slide is connected to the second slide through a connecting piece and a tension wheel module, and the enameled wire to be wound is kept on a vertical plane through the tension wheel module; the track motion system includes a first servo motor, and the first servo motor is connected to a horizontal iron rod that fixes the track of the coil to be wound;

[0009] The processor obtains the servo motor encoder value of the track motion system, and combines the servo motor line number, the reduction ratio and the track radius of the coil to be wound to obtain the number of orbital motion circles of the coil to be wound. The calculation formula is as follows:

[0010]

[0011] Among them, N represents the number of turns, L represents the path length, P represents the number of encoder pulses, R represents the encoder resolution (the number of pulses output per turn), i represents the reduction ratio (the ratio of input speed to output speed), and d represents the diameter of the enameled wire.

[0012] Preferably, the servo receives a PWM signal value transmitted by the processor according to the required mold shape, and changes the angle of its own steering wheel to cooperate with the track motion system to wind different coil shapes.

[0013] Preferably, the steering gear is connected to the movable platform of the second slide, the shape selection rod is connected to the steering gear, the shape mold is mounted on the shape selection rod, and a pressure sensor is attached to the bottom of the shape mold.

[0014] Preferably, the first servo motor is arranged at the outermost side of the winding machine and is connected to the iron rod on which the track of the coil to be wound is placed via a set screw.

[0015] Preferably, the starting end of the iron rod is provided with a hole for placing a set screw, the middle end is a smooth round rod for placing the coil track to be wound, and the tail end is a threaded rod, which is used to tighten the nut of the coil track to be wound.

[0016] Preferably, the wire feeding tension system comprises a tension wheel module, and the tension wheel module comprises at least three tension wheels arranged side by side.

[0017] Preferably, the processor controls the rotation speed of the tension wheel through a PID algorithm to stabilize the tension between the enameled wire and the tension wheel to a set value.

[0018] Preferably, the first servo motor, the second servo motor, the first slide, the second slide and the tension wheel module simultaneously feed back various operating parameters to the processor and receive motion signals processed by the processor.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The dual servo motors are used to automatically control the coil track and coil to be wound, which greatly reduces the difficulty of operation for users. The operator only needs to fix the coil track to be wound on the middle section of the iron rod, and modify the processor program according to his own needs and the scale value of the corresponding parameter below, which effectively improves the efficiency of batch winding.

[0021] 2. By matching the track motion system and the synchronous control system, the coil diameter is matched with the enameled wire stroke, and each turn of the coil is closely connected, which effectively improves the attraction of the building block track coil to the iron ball, effectively improves the aesthetics of the building block track coil, and reduces the difficulty of subsequent assembly.

[0022] 3. By selecting the shape limit mold, the building block track coil can be wound in different shapes, effectively improving the space utilization of the enameled wire. The processor changes the servo angle to switch between different shape limit molds and wind different coil shapes, effectively improving the diversity and adaptability of the product.

[0023] 4. The automatic winding machine of the internal coil of the track building block has multiple feedbacks, which effectively improves the stability and accuracy of the system. Changing the program of the processor can also easily realize the cross-winding technology that is difficult to achieve with the existing technology, which is a major breakthrough in technology.

[0033] The present invention is further described below in conjunction with specific embodiments.

[0034] like Figure 1-Figure 4 As shown, the present invention discloses an automatic winding machine for the internal coil of a track building block, comprising a wire feeding tension system, a track motion system, a synchronous control system and a shape limiting system.

[0035] The track motion system includes a first servo motor 1 and an iron rod 2, both of which are placed horizontally. The starting end of the iron rod 2 is provided with a screw hole 7 for placing a set screw, the middle end is a smooth round rod for placing the track of the coil to be wound, and the end is a threaded rod 8, which is used to tighten the nut of the track of the coil to be wound. Both ends are tightened at the same time to fix the iron rod 2, and the first servo motor is connected to its professional drive board to feedback the controller's position, speed, movement distance and other parameters.

[0036] The synchronous control system includes a second servo motor, a first slide 3 and a screw platform carrying the wire feeding tension system. The synchronous control system receives input instructions from the processor to match the coil diameter with the straight enameled wire stroke. The second servo motor drives the first slide 3 to move

[0037] The processor obtains the servo motor encoder value of the track motion system, and combines the servo motor line number, the reduction ratio and the track radius of the coil to be wound to obtain the number of orbital motion circles of the coil to be wound. The calculation formula is as follows:

[0038]

[0039] Among them, N represents the number of turns, L represents the path length, P represents the number of encoder pulses, R represents the encoder resolution (the number of pulses output per turn), i represents the reduction ratio (the ratio of input speed to output speed), and d represents the diameter of the enameled wire.

[0040] like Figure 5 and Figure 6 The wire feeding tension system shown includes a tension wheel module 6, and the axes of the three tension wheels in the tension wheel module 6 are in the same direction as the axis of the iron rod 2. The tension wheel obtains the tension through the tension sensor and feeds it back to the controller. The controller controls the rotation speed of the tension wheel through the PID algorithm to stabilize the tension between the enameled wire and the tension wheel to the set value.

[0041] like Figure 7 and Figure 8 As shown, the shape limiting system includes the second slide 4, the steering gear 5 and the shape selection rod. The second slide 4 is placed vertically, and its movable platform is perpendicular to the axis direction of the iron rod 2 and faces rightward, and is connected and fixed to the first slide 3. The steering gear 5 is connected to the movable platform of the second slide 4.

[0042] The shape selection rod is connected to the steering gear and moves on a plane perpendicular to the 2nd axis of the iron rod. Various shape molds are installed on the shape selector, and a pressure sensor is attached to the bottom. The pressure sensor is connected to the processor, and the feedback control pressure signal is used. The processor controls the movement of the first slide until the pressure value reaches the set value to ensure that the subsequent coil winding process remains tense. When the slide descends to the point where the pressure sensor detection value is greater than the set value, the automatic winding machine of the internal coil of the track building block stops the slide from descending to adapt to the height change caused by the increase in the number of coil layers during winding.

[0043] The following will further explain this product in conjunction with a specific implementation plan.

[0044] First, remove the iron rod 2, fix the coil track to be wound on the middle part of the iron rod 2, pull the enameled wire through the tension wheel module 6, pre-wrap two circles to determine the winding direction, fix the starting point of the enameled wire, and use set screws to fix the two ends of the iron rod 2 to the servo motor 1 and the fixing frame respectively.

[0045] Secondly, according to the fixed position of the coil track to be wound, read the corresponding scale below, set the path coordinates to be wound on the touch screen of the controller, install the required shape mold on the shape selection rod, and insert the number of the mold to be switched in front of each path coordinate according to the installed number.

[0046] Again, set the required tension in the menu on the display screen, and set the required and appropriate winding speed according to the indicated limit range.

[0047] Then, press the "Home Position" button in the menu, wait for it to return to its home position, and then click the "Start Winding" button. After a while, the automatic winding machine of the internal coil of the track building block will wind the coil set by the user.

[0048] Finally, the automatic winding machine of the internal coil of the track building block will automatically rise after the winding operation is completed, and the fixing screws at both ends of the iron rod 2 are loosened to remove the track of the coil to be wound, and the winding is completed.

[0049] If an error occurs during the winding process, the emergency stop button can be pressed, and the automatic winding machine of the internal coil of the track building block will return the coil to the pre-winding state according to the current position. At the same time, it will continuously flash a red light to remind the user not to operate the winding machine again during this period.

[0050] In the present invention, in order to further enhance the user experience, an indicator light with customizable functions is added. The design purpose of the indicator light is diversified, and its functions include but are not limited to providing prompts for the passing of the moving body and prompts for the effect when the deceleration is completed. This practice of adding an indicator light is intended to increase the interactivity between the user and the device, thereby improving the overall user satisfaction. The integration of this function is considered to be within the scope that can be easily achieved by technicians in this field based on conventional technical levels and existing knowledge, and allows for customized settings based on specific product requirements and design preferences.

[0051] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
