Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of winding machines, in particular to a winding jig suitable for winding a horizontal entry and exit of the start and end wires. BACKGROUND

[0002] A coil generally refers to a loop-shaped wire winding. The most common coil applications include motors, inductors, transformers, and loop antennas. For some special products, the position, orientation, and exit angle of the start and end wires of the coil are required. The start and end wire ends are required to be horizontally exited and entered, that is, the start and end wires are perpendicular to the extension direction of the coil skeleton, and the start and end wires also need to be on the same plane. Figure 9 The coil 100 includes a coil skeleton 110 and a wire 120 spirally wound on the coil skeleton 110. One end of the wire 120 is a start wire end 130, and the other end of the wire 120 is an end wire end 140. In order to meet the needs of wire arrangement, the wire is mostly spirally wound, so that the start wire end 130 and the end wire end 140 will inevitably be inclined during winding, making it difficult to ensure that the exit and entry of the start and end wire ends are perpendicular to the extension direction of the coil skeleton. The existing winding mechanism is difficult to meet such needs. At the same time, in order to make the start and end wires on the same plane, the end wire end 140 needs to be reversely bent after winding, so that the start wire end 130 and the end wire end 140 are on the same plane. The existing winding mechanism is also difficult to meet such needs, and the wire at the bending position is prone to looseness during bending, and cannot be tightly attached to the coil skeleton.

[0025] The following provides a more detailed description of specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.

[0026] like Figures 1 to 10 The diagram shows a schematic representation of the winding fixture for horizontal entry and exit of starting and ending wires provided by the present invention. The winding fixture includes a frame 10, a lower die assembly 20 mounted on the frame 10, an upper die assembly 30 mounted on the frame 10, a drive assembly 40 for rotating the lower die assembly 20 and the upper die assembly 30, and a wire clamp assembly 50 mounted on the lower die assembly 20. It is conceivable that the winding fixture for horizontal entry and exit of starting and ending wires may also include other functional modules, such as connecting components, sensors, and mounting components, etc., which are well-known to those skilled in the art and will not be described in detail here.

[0027] First of all, the winding jig suitable for winding the tail wire horizontally into the wire and out of the wire is used for winding the coil 100, the coil 100 comprises a coil framework 110 and a wire 120 spirally wound on the coil framework 110. One end of the wire 120 is the starting wire end 130, the other end of the wire 120 is the tail wire end 140, the coil 100 should be the prior art, and here is not described again.

[0028] The rack 10 is in a U-shaped structure and is used to carry the above-mentioned various functional modules, so the rack 10 is provided with various functional structures such as screws, bolts, through holes and the like to complete the installation and assembly of the above-mentioned functional modules, which can be set according to actual needs, and here is not described in detail.

[0029] The lower die assembly 20 comprises a first drive shaft 21 arranged on the rack 10, a lower die seat 22 arranged on the first drive shaft 21, a mounting seat 23 arranged on the lower die seat 22, a sliding block 24 slidingly arranged on the mounting seat 23, a first elastic member 25 arranged between the sliding block 24 and the mounting seat 23, a first pressing block 26 slidingly arranged on the sliding block 24, a second elastic member 27 arranged between the first pressing block 26 and the sliding block 24, a drive rod 28 slidingly arranged on the mounting seat 23, and a first unlocking assembly 29 arranged on the rack 10.

[0030] One end of the first drive shaft 21 is connected with the lower die seat 22, and the other end is connected with the drive assembly 40 and rotates under the drive of the drive assembly 40.

[0031] One end of the lower die seat 22 towards the upper die assembly 30 is provided with a first fixing port 221, one end of the coil framework 110 is inserted into the first fixing port 221, and after being fixed, the coil framework 110 is rotated to wind the wire 120 on the coil framework 110.

[0032] The mounting seat 23 is fixed on the lower die seat 22 and rotates with the lower die seat 22. The mounting seat 23 is used to support and arrange the sliding block 24 and the drive rod 28, so the mounting seat 23 is provided with a plurality of sliding grooves to complete the sliding limiting of the sliding block 24 and the drive rod 28.

[0033] The slider 24 is provided with a first pressing block 26 at one end and a first inclined surface 241 at the other end. The first elastic member 25 is abutted against the mounting seat 23 at one end and against the slider 24 at the other end. The slider 24 slides in the direction of approaching or moving away from the lower die seat 22, specifically, in the free state, the slider 24 is driven by the self-elastic force of the first elastic member 25 to move away from the lower die seat 22, so that the first pressing block 26 provided on the slider 24 does not press the wire. The first inclined surface 241 is used to be pushed by the driving rod 28, so as to drive the slider 24 to move towards the lower die seat 22 and the first elastic member 25 is compressed, so that the first pressing block 26 provided on the slider 24 presses the wire.

[0034] The first pressing block 26 is used to press the wire starting end 130. Since the wire is still in the horizontal state when it is wired, only the guide needle (not shown in the figure) provided with the wire will be adjusted in height during winding to realize spiral winding, therefore, the wire starting end 130 in the horizontal state is pressed by the first pressing block 26 before winding, so as to ensure the horizontal arrangement of the wire starting end 130.

[0035] The sliding connection between the first pressing block 26 and the slider 24 can be realized by inserting a connecting rod on the slider 24, and the first pressing block 26 is provided with a limiting groove, so that the two ends of the connecting rod are respectively slidably arranged in the limiting groove. The sliding mode should be the prior art, which will not be described here. The second elastic member 27 drives the first pressing block 26 to move towards the lower die seat 22 in the free state by the self-elastic force, when the first pressing block 26 has abutted and pressed the wire starting end 130 and the slider 24 is still under pressure, a certain degree of buffering is performed by the second elastic member 27, so as to reduce the pressure on the wire starting end 130, thereby avoiding crushing or deforming the wire starting end 130, and at the same time, the stability during rotation can be improved.

[0036] The sliding direction of the driving rod 28 is perpendicular to the sliding direction of the slider 24. One end of the driving rod 28 is provided with a second inclined surface 281, and the other end is provided with a sliding wheel 282. The second inclined surface 281 and the first inclined surface 241 abut, so that the slider 24 can be pushed to move when the driving rod 28 moves axially. Since it is necessary to keep the wire end 130 tight during winding, the first unlocking assembly 29 keeps the driving rod 28 in a circular motion state, and the sliding wheel 282 is used to reduce the friction with the first unlocking assembly 29 during circular motion. The driving rod 28 and the mounting seat 23 are further provided with a third elastic member 283. One end of the third elastic member 283 is fixedly connected with the mounting seat 23, and the other end is fixedly connected with the driving rod 28. When the first unlocking assembly 29 lifts the driving rod 28, the third elastic member 283 is compressed to store elastic potential energy. When the first unlocking assembly 29 resets, the third elastic member 283 also drives the driving rod 28 to reset by its own elastic force.

[0037] The first unlocking assembly 29 comprises a first circular ring 291, two first guide shafts 292 arranged on the first circular ring 291, two first limiting parts 293 respectively arranged at one end of the first guide shaft 292, and two fourth elastic members 294 respectively sleeved on the first guide shaft 292.

[0038] The first circular ring 291 is sleeved on the lower mold seat 22 and is spaced from the inside of the lower mold seat 22 to avoid affecting the movement of the first circular ring 291. The first circular ring 291 is located between the driving rod 28 and the rack 10, and is used to lift the driving rod 28 when moving axially.

[0039] The first guide shaft 292 movably penetrates through the rack 10. One end of the first guide shaft 292 is connected with the first circular ring 291, and the other end is connected with the first limiting part 293. One end of the fourth elastic member 294 abuts against the rack 10, and the other end abuts against the first limiting part 293. One end of the first guide shaft 292 is pushed by an external moving device, so that the first circular ring 291 is lifted and the driving rod 28 is pushed to move, and at the same time the fourth elastic member 294 is compressed. When the external moving device is reset and no longer pushes the first guide shaft 292, the fourth elastic member 294 drives the first guide shaft 292 to reset by its own elastic force.

[0040] The upper die assembly 30 comprises a second driving shaft 31, an upper die seat 32 arranged on the second driving shaft 31, an upper fixed seat 33 arranged on the upper die seat 32, a movable rod 34 inserted on the upper die seat 32, a cross rod 35 inserted on the movable rod 34, a rotating shaft 36 inserted on the upper die seat 32, a second pressing block 37 rotatably arranged on the rotating shaft 36, a limiting rod 38 arranged on the movable rod 34, and a second unlocking assembly 39 arranged on the machine frame 10.

[0041] One end of the second driving shaft 31 is connected with the upper die seat 32, and the other end is connected with the driving assembly 40 and rotates under the driving of the driving assembly 40.

[0042] The upper die seat 32 is in a cylindrical shape and is connected with the second driving shaft 31 and rotates together with the second driving shaft 31. The upper die seat 32 is provided with a movable hole 321 for accommodating the movement of the movable rod 34, and a sliding groove 322 for accommodating the movement of the cross rod 35. The central axis of the movable hole 321 is coaxially arranged with the central axis of the upper die seat 32. The central axis of the sliding groove 322 is perpendicular to the central axis of the movable hole 321 and extends in a direction parallel to the central axis of the movable hole 321. The sliding groove 322 is in communication with the movable hole 321.

[0043] The upper fixed seat 33 is provided with a second fixed port 331 at one end facing the lower die assembly 20, and the other end of the coil former 110 is inserted on the second fixed port 331.

[0044] One end of the movable rod 34 is provided with a limiting block 341, and the other end is provided with a groove 342 and is inserted with the limiting rod 38. A fifth elastic member 343 is sleeved on the movable rod 34, one end of the fifth elastic member 343 abuts against the limiting block 341, and the other end abuts against the upper fixed seat 33, so that the movable rod 34 is moved away from the lower die assembly 20, i.e. upwardly moved, by the elastic force of the fifth elastic member 343 itself.

[0045] The cross rod 35 is movably inserted at both ends in the sliding groove 322 and penetrates through the movable rod 34, so that when the second unlocking assembly 39 presses down the cross rod 35, the cross rod 35 is driven to slide along the sliding groove 322, thereby driving the movable rod 34 to press down and causing the fifth elastic member 343 to be compressed. After the second unlocking assembly 39 is reset, the movable rod 34 is also automatically reset by the elastic force of the fifth elastic member 343. The ends of the cross rod 35 are sleeved with rolling members, so as to reduce the friction with the second unlocking assembly 39 during rotation by rolling members.

[0046] The second pressing block 37 is in a hook shape and passes through the groove 342, one end of the second pressing block 37 is rotatably arranged on the rotating shaft 36, and the other end is used for pressing the tail wire end 140. Since the rotating shaft 36 is arranged on the upper die seat 32 and cannot move with the movable rod 34, when the horizontal rod 35 is pressed to drive the movable rod 34 to move, the one end of the second pressing block 37 rotates around the rotating shaft 36 as the rotating point, so that the other end of the second pressing block 37 is tightly attached to the tail wire end 140, and after winding, the tail wire end 140 is moved to a horizontal state by moving the guide needle with the guide wire.

[0047] The limiting rod 38 is located at the bottom of the second pressing block 37, when the second unlocking assembly 39 is reset, the movable rod 34 is automatically reset by the elastic force of the fifth elastic member 343, the limiting rod 38 is also moved upward to reset the second pressing block 37, and the tail wire end 140 is not pressed.

[0048] A sixth elastic member 381 is further arranged between the second pressing block 37 and the movable rod 34, when the coil framework is fixed by the second pressing block 37, the force is easily too large to cause damage to the guide wire by driving through the second unlocking assembly 39, the sixth elastic member 381 can have a certain buffering effect when the second pressing block 37 has abutted against the tail wire end 140 and the movable rod 34 is still pressing, the pressure on the second pressing block 37 is reduced, and the stability during rotation is improved.

[0049] The second unlocking assembly 39 includes a second ring 391, two second guide shafts 392 arranged on the second ring 391, two second limiting parts 393 respectively arranged at one end of the second guide shaft 392, and two seventh elastic members 394 respectively sleeved on the second guide shaft 392.

[0050] The second circular ring 391 is sleeved on the upper die seat 32 and is spaced from the upper die seat 32 on the inner side to avoid affecting the movement of the second circular ring 391. The second circular ring 391 is located between the cross rod 35 and the frame 10 and is used to press down the cross rod 35 when moving axially. The second guide shaft 392 is movably penetrated through the frame 10, one end of the second guide shaft 392 is connected with the second circular ring 391, and the other end is connected with the second limiting part 393. One end of the seventh elastic member 394 abuts against the frame 10, and the other end abuts against the second limiting part 393. By pushing one end of the second guide shaft 392 through an external moving device, the second circular ring 391 is pressed down and pushes the cross rod 35 to move, and at the same time the seventh elastic member 394 is compressed. When the external moving device is not pushing the second guide shaft 392 after resetting, the seventh elastic member 394 drives the second guide shaft 392 to move downward and reset through the elastic force of itself.

[0051] The driving assembly 40 includes a rotating mechanism 41 arranged on the frame 10 and an axial movement mechanism 42 arranged on the frame 10. The rotating mechanism 41 is composed of a rotating motor, a rotating shaft, a belt, and a bearing, etc. The two ends of the rotating shaft are connected with the first driving shaft 21 and the second driving shaft 31 through the belt respectively, so that when the rotating motor rotates the rotating shaft, the second driving shaft 31 and the first driving shaft 21 can be driven to rotate synchronously to perform a winding movement. The axial movement mechanism 42 is used to drive the first driving shaft 21 to move axially, so as to drive the upper die assembly 30 to move close to or away from the lower die assembly 20, to realize the clamping or unclamping of the upper die assembly 30 and the lower die assembly 20. The driving assembly 40 should be a prior art, and will not be described here.

[0052] The wire clamp assembly 50 is arranged on the lower die seat 22 and rotates with the lower die seat 22. The wire clamp assembly 50 is used to clamp one end of the wire to hold the coil wire, and the wire clamp assembly 50 should be a prior art, and will not be described here.

[0053] Before winding, the upper and lower ends of the coil former 110 are arranged in the first fixing port 221 and the second fixing port 331 respectively and are fixed by closing the mold. During winding, the wire is output from the wire storage cylinder and passes through the guide needle and is clamped by the wire clamp assembly 50. The guide needle is a component in the winding machine for guiding the wire to travel along a predetermined path during winding and is moved in position by a three-axis moving device, which should be prior art and will not be described here. At this time, since winding has not been performed, the position of the guide needle is moved to the same height as the wire clamp assembly 50, so that the starting wire end 130 is arranged horizontally. Then the first unlocking assembly 29 pushes the driving rod 28, the driving rod 28 drives the sliding block 24 to move towards the lower mold base 22, and the first elastic member 25 is compressed, so that the first pressing block 26 arranged on the sliding block 24 presses and holds the starting wire end 130. Then the upper mold assembly 30 and the lower mold assembly 20 are synchronously rotated by the driving of the driving assembly 40 to perform winding. During winding, the guide needle moves along the coil former 110, so that the wire is arranged neatly on the coil former 110. Since the horizontally arranged starting wire end 130 is pressed before rotation, the starting wire end 130 will remain horizontal even when the guide needle moves along the coil former during winding. After winding is completed, the second unlocking assembly 39 pushes the cross rod 35 to slide along the sliding groove 322, the cross rod 35 drives the movable rod 34 to press downward, so that one end of the second pressing block 37 rotates around the rotating shaft 36, and the other end of the second pressing block 37 abuts against the tail wire end 140. The position of the guide needle is moved to the same height as the last winding circle of the coil 100, and at this time the tail wire end 140 is arranged horizontally. Finally, the upper mold assembly 30 and the lower mold assembly 20 are reversed to bend the tail wire end 140, so that the starting wire end 130 and the tail wire end 140 are located in the same plane, and winding is completed.

[0054] For the fixation of the wire, the coil former 110 is preheated before winding to melt the glue on its surface, and the wire is adhered to the coil former 110 after winding. At the same time, after winding is completed, a heat gun is used to heat the paint on the surface of the wire to melt it, and after cooling, the paint is solidified.

[0055] Compared with the prior art, the lower die assembly 20 of the winding jig suitable for winding the tail wire with horizontal entry and exit of the starting wire is provided with a first pressing block 26 at one end of the sliding block 24 and a first inclined surface 241 at the other end. The sliding direction of the driving rod 28 is perpendicular to the sliding direction of the sliding block 24, and the driving rod 28 is provided with a second inclined surface 281 at one end, the second inclined surface 281 and the first inclined surface 241 abut each other, so that the sliding block 24 can be pushed to move when the driving rod 28 moves axially, so that the first pressing block 26 moves and presses the starting wire end 130 before winding. Therefore, the starting wire end 130 in the horizontal state is pressed by the first pressing block 26 before winding, so as to ensure the horizontal arrangement of the starting wire end 130, and avoid affecting the starting wire end 130 during subsequent winding. The movable rod 34 of the upper die assembly 30 is driven by the cross rod 35 to move, so that one end of the second pressing block 37 rotates around the rotating shaft 36 as the rotating point, so that the other end of the second pressing block 37 is tightly attached to the tail wire end 140, and the tail wire end 140 is moved to the horizontal state by moving the guide needle with the wire after winding.
