Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of coil flying arm winding, in particular to a double-station multi-head winding machine. BACKGROUND

[0002] The double-station multi-head winding machine is an automatic device for winding coils (such as motor stator coils, transformer coils, etc.), which is composed of a flying arm winding arm and a tension stabilizer;

[0003] The existing tension stabilizer usually adopts a spring-swinging arm structure, which compensates for the change of wire tension by using the pulling force of the spring to achieve dynamic balance. The existing technology usually has two or several fixed spring connection points on the swinging arm, and different connection points correspond to different tension levels, which cannot realize continuous tension adjustment.

[0004] In order to obtain different tensions, the operator needs to replace springs with different stiffness or replace the hanging point position. This process requires shutdown, disassembly and installation, which is complicated. When different products or wire diameters require different tensions, multiple specifications of springs need to be prepared, and the cost of spare parts is high.

[0005] In the traditional flying arm winding arm, the lead-in nozzle is usually fixedly installed at the end of the flying arm tube, and its direction and angle are usually fixed with the axis of the flying arm tube, which cannot be adjusted. The fixed structure cannot change the wire-out direction according to product requirements, and only the entire flying head or lead-in nozzle can be replaced. However, when the wire-out angle is fixed, the wire tension and wire-in slot angle during automatic wire arrangement are not easy to coordinate, which can easily cause irregular winding and uneven inter-wire gap.

[0006] To solve the above problems, the present application provides a double-station multi-head winding machine. SUMMARY

[0049] Further, as shown in Figure 9 Each nut 49 is provided with a stop washer between the adjacent U-shaped bracket 45, which is used to prevent the nut 49 from rotating relative to each other, thereby avoiding the loosening of the connecting plate 46.

[0050] In operation:

[0051] The device can set appropriate tension for different types of non-flat wire, the following are the detailed steps:

[0052] The staff rotates the cam handle in the cam handle 311, so that the cam in the cam handle rotates eccentrically, until the part with the smallest radius of the cam is opposite to the end face of the shaft sleeve, there is a clear gap between the cam and the end face of the shaft sleeve, at this time the shaft sleeve no longer extrudes the sliding block 39, so that the sliding block 39 can slide freely along the outer wall of the swing arm 22, so that the sliding block 39 is no longer locked, then the staff moves the sliding block 39 along the outer wall of the swing arm 22 according to the need of the tension size, the follower 310 moves together with the sliding block 39;

[0053] When high tension is needed, move the sliding block 39 towards the side close to the connecting point of the swing arm 22 and the tension stabilizer 2, when the sliding block 39 moves along the outer wall of the swing arm 22 towards the side close to the connecting fulcrum of the swing arm 22 and the tension stabilizer 2, the connecting frame 37 moves along the outer wall of the fixed frame 31 towards the side away from the fixed frame 31, in this process, the tension spring 36 is stretched longer, so that the force arm of the tension spring 36 (i.e. the vertical distance from the spring force line to the fulcrum) is shortened, further making the swing arm 22 lose balance, in order to return to the balance state, the swing arm 22 will rotate downward with the connecting fulcrum of the tension stabilizer 2 as the axis, until the moment of force between the swing arm 22 and the tension spring 36 is balanced again;

[0054] When low tension is needed, move the sliding block 39 towards the side away from the connecting point of the swing arm 22 and the tension stabilizer 2, when the sliding block 39 moves along the outer wall of the swing arm 22 towards the side away from the connecting fulcrum of the swing arm 22 and the tension stabilizer 2, the connecting frame 37 moves along the outer wall of the fixed frame 31 towards the side close to the fixed frame 31, in this process, the tension spring 36 rebounds, but is still in a stretched state, so that the force arm of the tension spring 36 is elongated, further making the swing arm 22 lose balance, in order to return to the balance state, the swing arm 22 will rotate upward with the connecting fulcrum of the tension stabilizer 2 as the axis, until the moment of force between the swing arm 22 and the tension spring 36 is balanced again;

[0055] When the value displayed on the force gauge 21 is about to rise or fall to the required high tension value or low tension value, the cam handle 311 is reversed, the cam rotates, and the outer contour radius gradually increases. The cam contacts and presses the end face of the shaft sleeve through eccentric rotation. When the cam handle rotates back to the initial position, the cam rotates to its maximum lift point, i.e., the position with the maximum eccentricity. At this time, the shaft sleeve presses the slider 39, thereby locking and fixing the slider 39, so that the slider 39 cannot freely slide along the outer wall of the swing arm 22 and is in a static state.

[0056] Subsequently, fine adjustment of the reference tension is performed:

[0057] When fine adjustment is performed, the operator can rotate the knob 34 forward or backward, so that the adjusting plate 35 moves downward or upward along the guide rod 32, thereby compressing or stretching the tension spring 36, while observing the value displayed on the force gauge 21. When the measured value reaches the required high tension value or low tension value, the rotation of the knob 34 is stopped.

[0058] In this way, as the slider 39 gradually approaches the connecting point of the swing arm 22 and the tension stabilizer 2, the force arm of the tension spring 36 is shortened, and the swing arm 22 becomes a "forceful lever". At this time, a slight deformation of the tension spring 36 can generate a large torque, and the wire must be pulled with a large force to move the swing arm 22. Therefore, the reference tension is high, which is suitable for winding thicker wires on the coil framework. When the slider 39 gradually moves away from the connecting point of the swing arm 22 and the tension stabilizer 2, the force arm of the tension spring 36 is lengthened, and the swing arm 22 becomes a "labor-saving lever", which is opposite to the "forceful lever". Therefore, the reference tension is low, which is suitable for winding thinner wires on the coil framework.

[0059] In the above process, the adjusting tension assembly in the device can adjust the force arm length and the pre-tension amount of the tension spring 36 by moving the connecting point between the slider 39 and the swing arm 22, without the need to replace tension plates 35 and fixed hanging points with different stiffnesses. By loosening the locking member, the adjusting can be performed by sliding, thereby reducing the debugging time. The existing technology has the problem of fixed adjusting range due to the pre-set two or more fixed connecting points on the swing arm 22, which correspond to different tension levels. When different products or wire diameters require different tensions, multiple specifications of tension springs 36 need to be prepared. In this way, the device sets the connecting point between the tension spring 36 and the swing arm 22 as a structure that can slide and be locked, thereby improving the adaptability of the coil framework to winding different types of non-flat conductive wires in the inductor manufacturing process.

[0060] The device can adjust the wire outlet direction of the lead wire nozzle 47. The detailed steps are as follows:

[0061] When it is necessary to wind different winding frames, the staff first rotates the cam handle in cam handle two 48 upward, so that the cam in the cam handle rotates eccentrically until the part with the smallest radius of the cam is opposite to the end face of the shaft sleeve, and there is a clear gap between the cam and the end face of the shaft sleeve, at this time the shaft sleeve no longer presses the rotating table 43, so that the rotating table 43 is no longer locked and can be freely rotated;

[0062] The staff can adjust the azimuth angle of the lead-in nozzle 47 as needed, when it is necessary to adjust the azimuth angle, the rotating table 43 can be rotated forward or reversed, the rotating table 43 drives the lead-in nozzle 47 on the connecting plate 46 to rotate forward or reverse together, at the same time the staff can observe the relationship between the pointer on the outer ring surface of the rotating table 43 and the direction of the scale disc on the upper surface of the disc 42, and record it, so that the next time when winding the same type of winding frame, it can be quickly adjusted;

[0063] When the azimuth angle adjustment of the lead-in nozzle 47 is completed, the staff reverses the cam handle in the cam handle two 48, the cam rotates, and its outer contour radius gradually increases, the cam contacts and presses the end face of the shaft sleeve through eccentric rotation, when the cam handle is rotated back to the initial position, the cam rotates to the maximum lift point, that is, the position with the maximum eccentricity, at this time the shaft sleeve presses the rotating table 43, so as to lock the rotating table 43, so that the rotating table 43 cannot be freely rotated and is in a static state;

[0064] The staff can also adjust the pitch angle of the lead-in nozzle 47 as needed, when adjusting the pitch angle of the lead-in nozzle 47, first, the staff disassembles the nut 49 fixed on the outer circular shaft of the connecting plate 46, then the staff can rotate the connecting plate 46 upward or downward according to the need, so as to adjust the pitch angle of the lead-in nozzle 47, at the same time the staff can observe the relationship between the pointer on the outer circular shaft of the connecting plate 46 and the direction of the scale disc on the outer wall of the U-shaped frame 45, and record it, so that the next time when winding the same type of winding frame, it can be quickly adjusted;

[0065] When the pitch angle adjustment of the lead-in nozzle 47 is completed, the staff tightens the nut 49 again, which completes the fixation of the lead-in nozzle 47, so that the lead-in nozzle 47 is in a static state;

[0066] In this way, the azimuth angle adjustment and the pitch angle adjustment of the lead-in nozzle 47, that is, the adjustment of the wire outlet direction, are completed, through the design of the lead-in nozzle 47 with adjustable angle, the wire guide no longer needs to replace the flying fork pipe 11, only the orientation of the lead-in nozzle 47 needs to be adjusted to adjust the wire outlet direction, so as to ensure that the wire smoothly and smoothly enters the winding groove of the winding frame, thereby improving the wire arrangement quality and consistency.

[0067] In the above process, the direction adjusting assembly in the device adjusts the wire outlet angle of the wire guide nozzle 47 according to the shape of the coil former or the winding direction, adjusts the azimuth angle and the pitch angle, adapts to various process requirements, solves the problem that the wire outlet angle of the wire guide nozzle 47 in the prior art cannot be adjusted after installation, and solves the problem that the fixed structure cannot meet the winding requirements of different coil formers, causing the wire to deviate in the winding position, resulting in a decrease in the winding quality of the coil former. In this way, the device can quickly adjust the angle of the wire guide nozzle 47 when winding coils of different types of formers, without replacing the wire guide nozzle 47.

[0068] In the above process, the tension adjusting assembly in the device cooperates with the direction adjusting assembly, the tension adjusting assembly and the direction adjusting assembly work together to improve the winding uniformity, effectively reduce the tension fluctuation of the wire, and form the best winding track in coordination, so that the turns of the coil former are more uniform, and the problem of irregular coil shape caused by mismatching of tension or wire outlet direction in the traditional structure is solved.

[0069] The above only describes the embodiments of the present application and does not limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
