Description

Technical Field

[0001] The present application relates to the technical field of winding devices, and in particular to an automatic winding device for flat coils. Background Art

[0002] During the winding process of flat coils, loose coils and breakage are prone to occur. Due to objective factors such as different wire batches and wire thickness errors, especially when winding thin wires, loose coils or breakage may still occur during the production process after the equipment is adjusted. The equipment needs to be adjusted according to production. Currently, flat wire winding is an independent device, and the transfer is done manually after the coil is wound, which is inefficient. Summary of the Invention

[0003] One of the purposes of the present application is to provide an automatic flat coil winding device.

[0004] In order to achieve the above objectives, the technical solution adopted in this application is: a flat coil automatic winding equipment, including a winding displacement module, a winding foot winding group is provided in the output direction of the winding displacement module, a winding motor group is connected in the input direction of the winding foot winding group, a pre-pressing mechanism group is provided in the output direction of the winding foot winding group, a wire cutting mechanism is provided on the pre-pressing mechanism group, and a lower winding head winding demolding group is provided on the side of the wire cutting mechanism.

[0005] Preferably, the front end of the pre-pressing mechanism group is detachably connected with two groups of connecting plates, each group of connecting plates is welded with a bracket, and the bracket is arranged in an L-shape as a whole.

[0007] Preferably, the first swing arm and the second swing arm are both arranged in an arc shape, and the first swing arm and the second swing arm are arranged up and down.

[0008] Preferably, the first swing arm and the second swing arm are both rotatably connected with a tightening wheel, and the arc length of the second swing arm is greater than the arc length of the first swing arm.

[0009] Preferably, hanging rods are provided on the side walls of the first swing arm and the bracket.

[0010] Preferably, one end of a return spring is hung on the hanging rods of the two first rocker arms, and the other ends of the two return springs are respectively hung on the hanging rods of the two brackets.

[0011] Preferably, the first swing arm and the second swing arm at the same horizontal position are both connected with a support rod, and the support rod is obliquely arranged on the connected first swing arm and the second swing arm.

[0012] Preferably, a connecting frame is rotatably connected to the support rod, and the connecting frame is arranged in a T-shape as a whole.

[0013] Preferably, a rubber wheel is rotatably connected to the connecting frame, and the rubber wheel is overlapped on the pre-pressing mechanism group.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] This is an automatic winding equipment for flat coils. After the wire is fed into the winding head, the winding stripping group of the lower winding head is displaced to the upper winding center column by the motor on the Z axis. After pre-pressing by the pre-pressing mechanism group, the servo motor performs winding. Similarly, the pre-pressing mechanism can be adjusted to adapt to products with different wire thicknesses. After winding, the wire is cut, and the winding stripping group of the lower winding head is separated from the center column and automatically unloaded. The coil pitch pre-pressing structure can be automatically adjusted through settings, and the upper winding head can automatically unload, which solves the problems of loose coils, breakage, and other defects in the equipment during product winding. After winding, the angle can be automatically adjusted to carry out the next step of automated production.

[0016] The flat coil automatic winding equipment is characterized in that a bracket is installed in front of a pre-pressing mechanism group, and the bracket can support a first swing arm and a second swing arm. The first swing arm and the second swing arm are respectively located on the upper and lower sides. When the first swing arm and the second swing arm rotate, their respective motion trajectories will not be affected. A connecting frame is provided at the position of the first swing arm and the second swing arm, and a rubber wheel is installed on the connecting frame. The rubber wheel is overlapped on the pre-pressing mechanism group. During the movement of the pre-pressing mechanism group, the corresponding rubber wheel will be driven to move as a whole. According to the different movement directions of the pre-pressing mechanism group, the driven swing arms will also be different. When the pre-pressing mechanism group moves upward, the first swing arm will be moved. When the pre-pressing mechanism group moves downward, the second swing arm will be moved. The first swing arm and the second swing arm are both opened in an eight-shaped shape. Due to the different arc lengths of the first swing arm and the second swing arm, the first swing arm and the second swing arm are staggered. According to the drive of the pre-pressing mechanism group, the first swing arm and the second swing arm at the same horizontal position will be close to each other, thereby tightening the passing flat wire. During the winding process, the wire will be in a taut state, thereby assisting the winding twice. The wire will not be easily loosened during the winding process, thereby improving the probability of successful winding. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0023] like Figures 1 to 4 As shown, the present invention provides an automatic flat coil winding device, including a winding displacement module 1, a winding foot winding group 3 is provided in the output direction of the winding displacement module 1, a winding motor group 2 is connected in the input direction of the winding foot winding group 3, a pre-pressing mechanism group 5 is provided in the output direction of the winding foot winding group 3, a wire cutting mechanism 6 is provided on the pre-pressing mechanism group 5, and a lower winding head winding demolding group 4 is provided on the side of the wire cutting mechanism 6.

[0024] During implementation, after the wire is fed into the winding head, the lower winding head winding stripping group 4 is displaced to the upper winding center column by the motor through the Z-axis, and is pre-pressed by the pre-pressing mechanism group 5 and then wound by the servo motor. Similarly, the pre-pressing mechanism can be adjusted to adapt to products with different wire thicknesses. After winding, the wire is cut, and the lower winding head winding stripping group 4 is separated from the center column and automatically unloaded. The coil pitch pre-pressing structure can be automatically adjusted through settings, and the upper winding head can automatically unload, which solves the problems of loose coils, breakage, and other defects in product winding. After winding, the angle can be automatically adjusted to carry out the next step of automated production.

[0025] The front end of the preload mechanism assembly 5 is detachably connected to two sets of connecting plates 7, each of which is welded to a bracket 10. The bracket 10 is generally L-shaped. This allows the bracket 10 to be fixed to the equipment and removable, facilitating subsequent maintenance and adjustment. The bracket 10 also constrains the first and second rocker arms 12, 14, allowing them to rotate within the bracket 10.

[0026] Each bracket 10 is rotatably connected to a first swing arm 12 and a second swing arm 14. The first swing arm 12 and the second swing arm 14 have the same shape. Once mounted on the bracket 10, the first swing arm 12 and the second swing arm 14 will not easily deviate, ensuring that when the bracket 10 rotates, the first swing arm 12 and the second swing arm 14 can swing according to the drive of the preload mechanism group 5.

[0027] The first and second swing arms 12, 14 are both arc-shaped and arranged vertically. When the first and second swing arms 12, 14 are mounted vertically, the preload mechanism 5 can drive the corresponding first and second swing arms 12, 14 to move during vertical adjustment. As the first and second swing arms 12, 14 move, they tighten, thereby tightening the wire.

[0028] The first and second swing arms 12, 14 are both rotatably connected to a tensioning pulley 13, and the arc length of the second swing arm 14 is greater than that of the first swing arm 12. The different arc lengths of the first and second swing arms 12, 14 allow for a staggered arrangement of the first and second swing arms 12, 14. This ensures that the first and second swing arms 12, 14 do not affect each other's motion trajectories during rotation, thereby ensuring that the first and second swing arms 12, 14, driven by the pre-compression mechanism assembly 5, can independently compress the wire.

[0029] A hanging rod 9 is provided on the side wall of the first swing arm 12 and the bracket 10. By installing the hanging rod 9 on the first swing arm 12 and the second swing arm 14, the hanging rod 9 can be connected to the return spring 8. The bracket 10 is provided with a similar hanging rod 9, and the return spring 8 can be located at the connection between the first swing arm 12 and the second swing arm 14.

[0030] One end of a return spring 8 is attached to the hanging rod 9 of each of the two first swing arms 12, and the other ends of the two return springs 8 are respectively attached to the hanging rod 9 of the two brackets 10. When the first swing arm 12 is tightened, the return spring 8 is stretched, causing the return spring 8 to expand. After the preload mechanism assembly 5 is reset, the return spring 8 can drive the first swing arm 12 to reset, thereby achieving the reset of the first swing arm 12. During the movement of the preload mechanism assembly 5, the tension formed between the first swing arm 12 and the line can drive the second swing arm 14 to reset, thus ensuring adjustment according to the next line size.

[0031] The first and second swing arms 12, 14, which are at the same horizontal position, are both connected to a support rod 11, which is arranged obliquely on the connected first and second swing arms 12, 14. When the corresponding support rods 11 are connected to the first and second swing arms 12, 14, the support rods 11 can be driven by the connecting frame 15 to push the corresponding first and second swing arms 12, 14, and the first and second swing arms 12, 14 can rotate, thereby driving the tension wheel 13 to move toward the line position, thereby tightening the line.

[0032] The support rod 11 is rotatably connected to a connecting frame 15, which is generally T-shaped. By setting up the connecting frame 15, the first swing rod 12 or the second swing rod 14 connected to each other can be set on both sides. The first swing rod 12 and the second swing rod 14 at the same horizontal position will be arranged in an "eight" shape, so that they can be close to each other to tighten the wire.

[0033] The connecting frame 15 is rotatably connected with a rubber wheel 16, which is overlapped on the pre-pressing mechanism group 5. By overlapping the rubber wheel 16 with the pre-pressing mechanism group 5, damage to the pre-pressing mechanism group 5 surfaces can be avoided.

[0034] During implementation, by installing a bracket 10 in front of the preloading mechanism group 5, the bracket 10 can support the first rocker arm 12 and the second rocker arm 14. The first rocker arm 12 and the second rocker arm 14 are respectively located on the upper and lower sides. When the first rocker arm 12 and the second rocker arm 14 rotate, they will not affect their respective motion trajectories. A connecting frame 15 is provided at the position of the first rocker arm 12 and the second rocker arm 14. A rubber wheel 16 is installed on the connecting frame 15. The rubber wheel 16 is overlapped on the preloading mechanism group 5. During the activity of the preloading mechanism group 5, the corresponding rubber wheel 16 will be driven to move as a whole. According to the different activity directions of the preloading mechanism group 5, the driven rockers will also be different. At the same time, when the pre-stressing mechanism group 5 moves up, the first rocker arm 12 will be activated, and when the pre-stressing mechanism group 5 moves down, the second rocker arm 14 will be activated. The first rocker arm 12 and the second rocker arm 14 are both opened in an eight-shaped shape. Since the arc lengths of the first rocker arm 12 and the second rocker arm 14 are different, the first rocker arm 12 and the second rocker arm 14 are staggered. Driven by the pre-stressing mechanism group 5, the first rocker arm 12 and the second rocker arm 14 at the same horizontal position will be close to each other, thereby tightening the passing flat wire. During the winding process, the wire will be in a taut state, thereby assisting the winding for the second time. It is less likely that the wire will be loose during the winding process, thereby increasing the probability of successful winding.

[0035] The working principle of the present invention is as follows: after the wire is fed into the winding head, the lower winding head winding stripping group 4 is displaced to the upper winding center column by the motor through the Z-axis, and is pre-pressed by the pre-pressing mechanism group 5 and then the servo motor is used for winding. Similarly, the pre-pressing mechanism can be adjusted to adapt to products with different wire thicknesses. After winding, the wire is cut, and the lower winding head winding stripping group 4 is separated from the center column and automatically unloaded. The coil pitch pre-pressing structure can be automatically adjusted by setting, and the upper winding head can automatically unload, which solves the problems of loose coils, breakage, etc. in the product winding. After winding, the angle can be automatically adjusted to carry out the next step of automated production. By installing a bracket 10 in front of the pre-pressing mechanism group 5, the bracket 10 can support the first pendulum arm 12 and the second pendulum arm 14. The first pendulum arm 12 and the second pendulum arm 14 are respectively located on the upper and lower sides. When the first pendulum arm 12 and the second pendulum arm 14 rotate, they will not affect their respective motion trajectories. The positions of the first pendulum arm 12 and the second pendulum arm 14 are uniform. A connecting frame 15 is provided, and a rubber wheel 16 is installed on the connecting frame 15. The rubber wheel 16 is overlapped on the pre-stressing mechanism group 5. During the movement of the pre-stressing mechanism group 5, the corresponding rubber wheel 16 will be driven to move as a whole. According to the different movement directions of the pre-stressing mechanism group 5, the driven rocker will also be different. When the pre-stressing mechanism group 5 moves up, the first rocker 12 will be moved, and when the pre-stressing mechanism group 5 moves down, the second rocker 14 will be moved. The first rocker 12 and the second rocker 14 are both opened in an eight-shaped shape. Since the arc lengths of the first rocker 12 and the second rocker 14 are different, the first rocker 12 and the second rocker 14 are staggered. According to the drive of the pre-stressing mechanism group 5, the first rocker 12 and the second rocker 14 at the same horizontal position will be close to each other, thereby tightening the passing flat wire. During the winding process, the wire will be in a taut state, thereby assisting the winding for the second time. It is not easy for the wire to loosen during the winding process, thereby increasing the probability of successful winding.
