Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of radio frequency transformer manufacturing, in particular to a twisted wire making device for a small radio frequency transformer. Background Art
[0002] In the field of small RF transformer manufacturing, that is, RF transformers with a size of less than 6mm, core-wire design is usually adopted, that is, enameled wire is directly wound on the ferrite core to achieve signal transmission and matching to optimize signal transmission efficiency and quality. Core-wire transformers can be designed as one or more secondary windings and can have a center tap used as a balanced signal distributor to obtain good amplitude and phase balance.
[0003] The winding type and method of RF transformers are important aspects of transformer design, which directly affect the performance and efficiency of the transformer. Winding types include single-wire winding, double-wire twisted winding, multi-wire twisted winding, multi-wire (group) parallel winding, equal winding, multi-layer dense winding, positioning winding, etc. For small-scale production or prototype production of small RF transformers, enameled wire with a wire diameter of Φ0.07mm~Φ0.2mm is often used. The double or multi-strand wires are twisted together by hand and then wound into the magnetic core.
[0004] Twisting two or more wires can reduce the capacitive effect between coils, because each wire will alternately be in the high-voltage and low-voltage areas of the electric field during the winding process, thereby reducing the electric field coupling between coils. It can also reduce crosstalk between adjacent coils and improve the anti-interference ability of the transformer. This multi-wire twisting together can form a tight winding structure, which can enhance the magnetic coupling effect between the magnetic core and the coil. The stronger the magnetic coupling effect, the higher the efficiency of the transformer in transmitting and converting RF signals. At the same time, by twisting multiple wires, the turn density of the coil can also be increased, thereby increasing the inductance value and quality factor of the transformer. These performance improvements help the transformer work better in high-frequency environments.
[0005] In RF transformers, due to the high operating frequency, the use of twisted wire winding technology can reduce the loss caused by skin effect and proximity effect. The winding method of double or multi-wire twisting has many advantages in the production of RF transformers, which helps to improve the performance and reliability of the transformer. The tightness of the twisted wire will directly affect the distributed capacitance of the RF transformer, and thus affect the working efficiency and signal transmission quality of the transformer. If it is twisted too loosely, it may cause the gap between the coils to be too large, increase the distributed capacitance, and thus reduce the Q value and stability of the transformer; twisting too tightly may cause insulation problems between the coils, increase the resistance loss of the coils, and also affect the performance of the RF transformer.
[0006] However, in the prior art, the enameled wires in small RF transformers are mostly twisted manually, which can easily cause problems such as over-twisting, single wire breakage, loose strands, and large twist pitch. Utility Model Content

The bottom of the second support rod 42 is fixedly connected to the outer wall of the ball spline 9, so that the second support rod 42 can move along the axis of the fixed rod 10 toward or away from the first support rod 41. By providing the ball spline 9 and the fixed rod 10, and providing the groove 101 on the fixed rod 10, it is possible to reduce the friction coefficient of the ball spline 9 on the fixed rod 10, thereby reducing the friction of the first support rod 41 when moving, so that the movement is smoother.

[0052] Through the above structure, the working principle of a twisted wire making device for a small radio frequency transformer in this embodiment is as follows:
[0053] like Figure 1As shown, the device is first assembled. Then, the same end of at least two strands of enameled wire is placed on the silicone pad 437 on the first clamping plate 433 on the first support rod 41, and then the knob is turned to drive the threaded rod 435 to rotate, so that the second clamping plate 434 is vertically lowered along the guide groove 4321, so that the silicone pad 437 on the second clamping plate 434 cooperates with the silicone pad 437 on the first clamping plate 433 to clamp at least two strands of enameled wire. After at least two strands of enameled wire are clamped by the first clamping plate 433 and the second clamping plate 434 on the first support rod 41, take the other end of the at least two strands of enameled wire and place it on the silicone pad 437 on the first clamping plate 433 on the second support rod 42, then screw the knob on the top of the threaded rod 435 on the second support rod 42 to drive the threaded rod 435 to rotate, and then drive the second clamping plate 434 on the second support rod 42 to move vertically along the guide groove 4321 on the guide plate 432 until the silicone pad 437 on the second clamping plate 434 cooperates with the silicone pad 437 on the first clamping plate 433 to clamp at least two strands of enameled wire.
[0054] After all preparations are completed, press the switch button 8 to start the motor 21. The output end of the motor 21 drives the worm to rotate, thereby driving the worm wheel to rotate, and then driving the first transmission wheel 31 to rotate. Due to the effect of the transmission belt 33, the second transmission wheel 32 is driven to rotate, and then the transmission shaft 34 is driven to rotate. Thereby driving the rotary code disk in the rotary encoder 5 to rotate, and then driving the mounting plate 431, the guide plate 432, the first clamping plate 433, the second clamping plate 434 and the threaded rod 435 on the first support rod 41 to rotate. In this way, at least two enameled wires are twisted. At the same time, the rotary encoder 5 counts the number of turns of the transmission shaft 34, and transmits the electrical signal of the counted number of turns to the controller 7. The controller 7 processes the electrical signal of the number of turns and transmits it to the display screen 6 for display, thereby checking the number of twisted turns of at least two enameled wires and obtaining the number of turns of their binding. During the twisting process, since the length of at least two enameled wires gradually decreases, the second support rod 42 and the ball spline 9 are driven to move along the axis of the fixed rod 10 to adapt to the length of at least two enameled wires.
[0055] When the number of turns reaches the specified number, the shutdown button is immediately pressed to stop the driving of the motor 21. Then the knob is turned in the opposite direction to rotate the threaded rod 435 on the first support rod 41, so that the two clamping plates on the first support rod 41 rise vertically and move away from the first clamping plate 433, thereby detaching one end of at least two enameled wires from the clamping. The other end is detached from the first clamping plate 433 and the second clamping plate 434 on the second support rod 42 using the same operation method, and then removed to complete the twisting of at least two enameled wires.
[0056] It should be noted that the calculation of the number of revolutions by the rotary encoder 5 is a prior art, and its structure and working principle will not be described in detail here.
[0057] It should be noted that this embodiment does not involve the improvement and use of any computer program, but only provides the connection relationship between the motor 21, the display screen 6, the button 8 and the controller 7. The improvement of the utility model does not involve the content of the control aspect, and the existing control process is the existing content.
[0058] Embodiment 2
[0059] like Figure 4 As shown, different from the first embodiment, the clamping assembly 43 in this embodiment includes a mounting plate 431 , a guide plate 432 , a first clamping plate 433 , a second clamping plate 434 and a bidirectional threaded rod 436 .
[0060] Specifically, the back side wall of the mounting plate 431 is connected to one end of the transmission mechanism 3, the guide plate 432 is mounted on the side wall of the mounting plate 431 away from the transmission mechanism 3, and a guide groove 4321 is provided on the side wall of the guide plate 432 away from the mounting plate 431. The same end of the first clamping plate 433 and the second clamping plate 434 are both placed in the guide groove 4321, the first clamping plate 433 and the second clamping plate 434 are arranged opposite to each other and the second clamping plate 434 is located above the first clamping plate 433, and the bidirectional threaded rod 436 passes through the second clamping plate 434 and the first clamping plate 433 in sequence. The bidirectional threaded rod 436 can rotate to simultaneously drive the first clamping plate 433 and the second clamping plate 434 to move relative to or away from each other along the guide groove 4321 to clamp or release at least two strands of enameled wire. By providing a bidirectional threaded rod 436, the first clamping plate 433 and the second clamping plate 434 can be moved relative to or opposite to each other at the same time, so as to clamp or release at least two strands of enameled wires. Moreover, through the fine adjustment capability of the bidirectional threaded rod 436, the operator can more accurately control the clamping degree of the enameled wires, and even a small spacing adjustment can be easily achieved, thereby reducing wire damage or twisting problems caused by improper adjustment, and improving production efficiency and finished product qualification rate. A guide groove 4321 is provided, which can limit the moving directions of the first clamping plate 433 and the second clamping plate 434.
[0061] The driving mechanism 2 and the transmission mechanism 3 in the first embodiment are also applicable to the transmission of the clamping assembly 43 in this embodiment, and simultaneously drive the mounting plate 431, the guide plate 432, the first clamping plate 433, the second clamping plate 434 and the bidirectional threaded rod 436 to rotate, so as to achieve the effect of twisting at least two strands of enameled wire.
