Description

Technical Field

[0001] The present invention relates to a winding device, and particularly to a winding device for winding a bobbin with a wire. Background Art

[0002] A winding machine is a device for winding a wire around an electronic component to form a winding. The electronic components include transformers, inductors, and buzzers, etc. A buzzer is also called a horn. When manufacturing a buzzer, a hot melt wire needs to be wound around a bobbin for a set number of turns, and it is required that the two wire ends of the winding face the same side of the winding, that is, both wire ends face upward. At present, the existing winding devices or equipment usually set the bobbin and the like on a winding shaft, and complex tangent mechanisms and wire arranging mechanisms need to be set up and cooperate with each other to complete the wire arranging of the two wire ends. The structure is complex and the steps are numerous, resulting in low winding efficiency. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this purpose, the present invention provides a winding device of a winding machine, which can make both the wire head and the wire tail on the bobbin face upward, has a relatively simple structure, and has a high winding efficiency.

[0004] A winding device of a winding machine according to an embodiment of the present invention includes: a frame provided with a bracket capable of moving in the front-rear, left-right, and up-down directions; a winding group including a rotating shaft, a wire outlet needle, a first wire head clamp, a first elastic member, a second lifting driving mechanism, and a first lifting driving mechanism. The rotating shaft is rotatably provided on the bracket. The wire outlet needle is provided on the rotating shaft. The wire outlet needle is provided with a wire passing hole for a wire to pass through. The first wire head clamp is capable of lifting and lowering on the rotating shaft. The first elastic member is used to force the first wire head clamp to move upward. The output end of the first lifting driving mechanism is used to drive the first wire head clamp to move downward to realize the lowering and rising of the first wire head clamp. The first wire head clamp includes a second elastic member, a first clamping arm, and a second clamping arm. The second elastic member is used to force the second clamping arm to move upward so that the first clamping arm and the second clamping arm clamp the wire. The output end of the second lifting driving mechanism is used to drive the second clamping arm to move downward so that the first clamping arm and the second clamping arm release the wire; a bobbin clamp for clamping the bobbin; a fixed wire head device including a second wire head clamp capable of moving in the front-rear and up-down directions. The second wire head clamp is close to the winding group and receives the wire head on the first wire head clamp. The second wire head clamp clamps and positions the wire head. The rotating shaft drives the wire outlet needle to rotate so that the wire is wound around the bobbin. The first wire head clamp receives the wire head from the second wire head clamp. The first wire head clamp moves upward and releases the wire head so that the wire head faces upward. The first wire head clamp straightens the wire between the wire outlet needle and the bobbin.

[0005] A tangent device for cutting the wire between the skeleton and the first wire head clamp, so that an upward wire tail is formed on the skeleton.

[0006] It has at least the following beneficial effects:

[0007] Initially, the wire head of the wire passes through the wire passing hole from top to bottom, and the wire head is placed on the first wire head clamp. The first wire head clamp clamps the wire head. The second wire head clamp and the tangent device are both far away from the winding group and the skeleton clamp. The skeleton is placed on the skeleton clamp. At this time, the skeleton is below the winding group. Then the second wire head clamp moves in the front-back and up-down directions, so that the second wire head clamp clamps the wire between the wire outlet needle and the first wire head clamp. The first wire head clamp releases the wire head. At this time, the second wire head clamp does not move to complete the positioning of the wire head. Then the driving device drives the bracket and the rotating shaft to move in the front-back, left-right and up-down directions. The rotating shaft carries the wire outlet needle to move. The wire outlet needle pulls the wire across the winding column of the skeleton. Immediately afterwards, the rotating shaft rotates, so that the wire outlet needle rotates around the skeleton, realizing winding multiple turns of wire on the skeleton, so that a winding is formed on the skeleton. The rotating shaft moves again in the front-back, left-right and up-down directions, so that the first wire head clamp returns to the initial position. The first wire head clamp takes back the wire head from the second wire head clamp. The second wire head clamp resets. Then the rotating shaft carries the first wire head clamp upwards. The first wire head clamp pulls the wire head upwards. Then the first wire head clamp releases the wire head, so that the wire head faces upwards. After the first wire head clamp releases the wire head, the rotating shaft drives the first wire head clamp to rotate, so that the first wire head clamp clamps the tail end of the wire, that is, the first wire head clamp is in a state of clamping the wire between the wire outlet needle and the skeleton. Then the rotating shaft drives the first wire head clamp to move upwards. The first wire head clamp straightens the wire and makes the wire between the first wire head clamp and the skeleton gradually stand up. Then, the cutter moves in the front-back and up-down directions. When the cutter is in the lower projection area of the wire between the first wire head clamp and the skeleton, the cutter moves upwards from the area between the first wire head clamp and the skeleton. When the cutter rises to a height close to the first wire head clamp, the wire is cut off. The wire is at the port area close to the first wire head clamp, completing the cutting of the wire between the first wire head clamp and the skeleton, so that the wire on the skeleton forms an upward wire tail, and the wire clamped by the first wire head clamp forms a new wire head. During the process of the winding device winding the wire on the skeleton, the hot air device conveys hot air to the wire on the skeleton, so that the wire is fixed on the skeleton. Through the cooperation of the winding group, the fixed wire head device and the tangent device, not only the winding of the skeleton is completed, but also the wire head and the wire tail on the skeleton face upwards. There is no need to set up a wire arranging mechanism, and the structure of the tangent device is relatively simple. The structure of the winding device is relatively simple and compact. The winding steps are less and simple, which can effectively improve the winding efficiency.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0036] In the description of the present invention, if the first and second are described only for the purpose of distinguishing technical features, it should not be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0037] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installation, connection, etc. should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0038] Referring to Figure 1 , the structure of the skeleton is disclosed. The skeleton includes a top plate and a wire winding post provided on the lower surface of the top plate. The structure of the top plate is symmetric in the left - right and front - back directions. There are two symmetric notches on the top plate. The wire winding post is for winding the wire, and both the head and the tail of the wire can extend into the notches.

[0039] Referring to Figures 2 to 5 , the present invention discloses a wire winding device of a winding machine, including: a frame 100, a wire winding group 300, a skeleton clamp, a fixed wire head device 400, a wire cutting device 500, and a hot air device 600.

[0040] A driving device 110 is provided on the frame 100. A bracket 200 is provided at the output end of the driving device 110. The driving device 110 is used to drive the bracket 200 to move in the front - back, left - right, and up - down directions, and the driving device 110 realizes driving the bracket 200 to move in a three - dimensional space.

[0041] Referring to Figure 5 and Figure 6, the winding group 300 includes a rotating shaft 310, a wire outlet needle 320, and a first wire head clamp 330. The rotating shaft 310 is rotatably arranged on the bracket 200. The wire outlet needle 320 is arranged on the rotating shaft 310. A wire passing hole for the wire to pass through is provided on the wire outlet needle 320. The wire passing hole is eccentrically arranged with respect to the rotation axis of the rotating shaft 310. The first wire head clamp 330 is vertically movable on the rotating shaft 310, and the first wire head clamp 330 is used to clamp or release the wire head. A first rotation driving mechanism is provided on the bracket 200. The output end of the first rotation driving mechanism is in transmission connection with the rotating shaft 310. The first rotation driving mechanism drives the rotating shaft 310 to rotate on the bracket 200. The rotating shaft 310 rotates itself. The rotating shaft 310 drives the wire outlet needle 320 and the first wire head clamp 330 to rotate. Both the wire outlet needle 320 and the first wire head clamp 330 rotate around the rotation axis of the rotating shaft 310.

[0042] The skeleton fixture is arranged below the winding group 300 and is used to clamp the skeleton. The rotating shaft 310 is vertical on the bracket 200, and the rotating shaft 310 takes the up-and-down direction as the rotation axis direction. The skeleton fixture is a common component on the market. The winding post of the skeleton extends into the opened skeleton fixture, and then the skeleton fixture can be closed to clamp the skeleton. When the skeleton fixture is opened again, the skeleton can be taken away from the skeleton fixture.

[0043] Refer to Figure 2 and Figure 8 , the fixed wire head device 400 includes a second wire head clamp 410 that can move in the front-back and up-down directions. The second wire head clamp 410 approaches the winding group 300 and receives the wire head on the first wire head clamp 330. The second wire head clamp 410 clamps and positions the wire head. The rotating shaft 310 drives the wire outlet needle 320 to rotate so that the wire is wound around the skeleton. The first wire head clamp 330 receives the wire head from the second wire head clamp 410. The first wire head clamp 330 moves upward and releases the wire head so that the wire head faces upward. The first wire head clamp 330 straightens the wire between the wire outlet needle 320 and the skeleton.

[0044] Refer to Figure 2 and Figure 9 , the wire cutting device 500 includes a cutter 510 that can move in the front-back and up-down directions. The cutter 510 cuts the wire between the skeleton and the first wire head clamp 330 so that a wire tail facing upward is formed on the skeleton.

[0045] The hot air device 600 is used to convey hot air to the wire on the skeleton so that the wire is shaped on the skeleton. The wire is a heat-melting type wire. By heating the wire with hot air or other means, the wire can be softened, so that it is convenient to shape the wire. After shaping, the wire can maintain a good shape, that is, be shaped. The heat-melting type wire is a common component on the market.

[0046] It can be understood that the wire fixing head device 400 and the hot air device 600 are both arranged in front of the winding group 300 , and the wire cutting device 500 is arranged behind the winding group 300 .

[0047] When the winding device winds the wire around the skeleton, initially, the wire end of the wire passes through the wire hole from top to bottom and is placed on the first wire end clamp 330. The first wire end clamp 330 clamps the wire end, and the second wire end clamp 410 and the wire cutting device 500 are both away from the winding group 300 and the skeleton clamp. The skeleton is placed on the skeleton clamp. At this time, the skeleton is below the winding group 300; then the second wire end clamp 410 moves in the front-to-back and up-and-down directions so that the second wire end clamp 410 clamps the wire between the outlet needle 320 and the first wire end clamp 330, and the first wire end clamp 330 releases the wire end. At this time, the second wire end clamp 41 0 can complete the positioning of the thread end; then the driving device 110 drives the bracket 200 and the rotating shaft 310 to move in the front-to-back, left-to-right and up-to-down directions, the rotating shaft 310 carries the wire outlet needle 320 to move, the wire outlet needle 320 pulls the wire across the winding column of the frame, and then the rotating shaft 310 rotates, so that the wire outlet needle 320 rotates around the frame, so that multiple turns of wire are wound around the frame, so that a winding is formed on the frame; the rotating shaft 310 moves in the front-to-back, left-to-right and up-to-down directions again, so that the first thread end clamp 330 returns to the initial position, and the first thread end clamp 330 is connected back from the second thread end clamp 410 The first thread end clamp 330 is reset, and then the rotating shaft 310 carries the first thread end clamp 330 to move upward, the first thread end clamp 330 pulls the thread end upward, and then the first thread end clamp 330 releases the thread end so that the thread end faces upward. After the first thread end clamp 330 releases the thread end, the rotating shaft 310 drives the first thread end clamp 330 to rotate so that the first thread end clamp 330 clamps the tail end of the wire, that is, the first thread end clamp 330 is in a state of clamping the wire between the outlet needle 320 and the frame, and then the rotating shaft 310 drives the first thread end clamp 330 to move upward, the first thread end clamp 330 straightens the wire and makes the first thread end clamp 33 0 and the frame gradually stand up; then, the cutter 510 moves in the front-back and up-down directions. When the cutter 510 is in the lower projection area of the wire between the first wire end clamp 330 and the frame, the cutter 510 moves upward from the area between the first wire end clamp 330 and the frame. When the cutter 510 rises to a height close to the first wire end clamp 330, the wire is cut off. The wire is at the port of the area close to the first wire end clamp 330, and the wire between the first wire end clamp 330 and the frame is cut off, so that the wire on the frame forms an upward wire tail, and the wire clamped by the first wire end clamp 330 forms a new wire end. In the process of the winding device winding the wire on the frame, the hot air device 600 delivers hot air to the wire on the frame to shape the wire on the frame.

[0048] It can be understood that the first wire head clamp 330 can fixedly clamp the wire head. When the first wire head clamp 330 clamps the wire between the wire outlet needle 320 and the skeleton, the clamping force of the first wire head clamp 330 is relatively small, so that the wire can slide on the first wire head clamp 330. The first wire head clamp 330 functions to hook the wire between the wire outlet needle 320 and the skeleton, so that the wire between the first wire head clamp 330 and the skeleton gradually grows and gradually assumes an upright state.

[0049] Through the cooperation of the winding group 300, the fixed wire head device 400 and the wire cutting device 500, not only the winding of the skeleton is completed, but also the wire head and wire tail on the skeleton can be made to face upward. There is no need to set up a wire arranging mechanism, and the structure of the wire cutting device 500 is relatively simple. The structure of the winding device is relatively simple and compact, the winding steps are fewer and simpler, and the winding efficiency can be effectively improved.

[0050] Since both the wire outlet needle 320 and the first wire head clamp 330 are provided on the rotating shaft 310, when the first wire head clamp 330 clamps and releases the wire head, the wire outlet needle 320 may interfere with the skeleton clamp, the fixed wire head device 400, the hot air device 600, etc. When the wire outlet needle 320 rotates around the central axis of the winding group 300, the first wire head clamp 330 may interfere with the skeleton clamp, the fixed wire head device 400, the hot air device 600, etc. Therefore, it is necessary to be able to adjust the height of the first wire head clamp 330 so that the wire outlet needle 320 and the first wire head clamp 330 are staggered in the up and down direction, thereby preventing the first wire head clamp 330 from interfering with other components.

[0051] The first wire head clamp 330 is capable of lifting and lowering and is provided on the rotating shaft 310. According to the actual situation, the height of the first wire head clamp 330 is changed, the relative height between the wire outlet needle 320 and the first wire head clamp 330 is changed, and the height of the first wire head clamp 330 is adjusted so that the first wire head clamp 330 is in a suitable height position to avoid interference between the wire outlet needle 320 and other components when the first wire head clamp 330 is working.

[0052] Specifically, when the first wire head clamp 330 clamps the wire head, the first wire head clamp 330 can be lowered to a low position, that is, the wire outlet needle 320 is in a higher position, to avoid interference between the wire outlet needle 320 and the skeleton, the skeleton clamp, etc.; when the rotating shaft 310 drives the wire outlet needle 320 to rotate to wind the wire on the skeleton, the first wire head clamp 330 rises to a high position to avoid interference between the first wire head clamp 330 and the skeleton, the skeleton clamp, the second wire head clamp 410, etc.

[0053] Refer to Figures 5 to 7, in some of these embodiments, the winding group 300 further includes a first lifting drive mechanism 350 and a second lifting drive mechanism 340. The first wire head clamp 330 includes a first elastic member 332, a second elastic member 331, a first clamping arm 333, and a second clamping arm 334.

[0054] The first clamping arm 333 includes a first sliding portion 333a and a first clamping portion 333b provided at the lower end of the first sliding portion 333a. The first sliding portion 333a is slidably provided on the rotating shaft 310 in the up and down direction. The second clamping arm 334 includes a second sliding portion 334a and a second clamping portion 334b provided at the lower end of the second sliding portion 334a. The second sliding portion 334a is slidably provided on the first sliding portion 333a in the up and down direction. The second clamping portion 334b is located below the first clamping portion 333b. The second elastic member 331 is used to force the second sliding portion 334a to move upward so that the first clamping portion 333b and the second clamping portion 334b clamp the wire head or the wire between the lead-out needle 320 and the skeleton. The output end of the second lifting drive mechanism 340 is used to drive the second sliding portion 334a to move downward so that the first clamping portion 333b and the second clamping portion 334b release the wire head. In the natural state, the second elastic member 331 forces the second sliding portion 334a to move upward, causing the second clamping portion 334b to approach the first clamping portion 333b, and further causing the second clamping portion 334b and the first clamping portion 333b to remain in a clamping state. The second clamping portion 334b and the first clamping portion 333b can clamp the wire head or the wire between the lead-out needle 320 and the skeleton. When the second lifting drive mechanism 340 drives the second sliding portion 334a to move downward, the second clamping portion 334b moves downward to move away from the first clamping portion 333b, and the wire head can be released.

[0055] It can be understood that the first wire head clamp 330 is used for positioning the wire head and does not need to clamp the wire head / wire. Therefore, the second elastic member 331 only needs to maintain a moderate elastic force so that the second clamping portion 334b and the first clamping portion 333b can clamp and stabilize the wire head / wire, and at the same time, the wire can pass through between the second clamping portion 334b and the first clamping portion 333b, that is, hook the tail end of the wire.

[0056] The first elastic member 332 is used to force the first sliding portion 333a and the second sliding portion 334a to move upward, and the output end of the first lifting driving mechanism 350 is used to drive the first sliding portion 333a to move downward, so as to realize the lowering and rising of the first wire head clamp 330. In the natural state, the first elastic member 332 forces the first sliding portion 333a to move upward and be in the high position, and the first clamping arm 333 drives the second clamping arm 334 to move upward synchronously, so that the first clamping arm 333 and the second clamping arm 334 are in the high position; and when the first lifting driving mechanism 350 drives the first sliding portion 333a to move downward, the first clamping arm 333 carries the second clamping arm 334 to move downward synchronously, thereby realizing the adjustment of the height of the first wire head clamp 330.

[0057] Referring to Figures 5 to 7 , in some of these embodiments, a vertical first guiding hole 311 is provided on the rotating shaft 310, the first sliding portion 333a is inserted through the first guiding hole 311, the upper end of the first sliding portion 333a extends above the first guiding hole 311, the output end of the first lifting driving mechanism 350 is above the first sliding portion 333a, the lower end of the first sliding portion 333a extends below the rotating shaft 310 and is connected to the first clamping portion 333b, and the first guiding hole 311 serves to guide the sliding direction of the first sliding portion 333a.

[0058] A second guiding hole is provided through the first sliding portion 333a, the second sliding portion 334a is inserted through the second guiding hole, the upper end of the second sliding portion 334a extends above the second guiding hole and is above the first sliding portion 333a, the output end of the second lifting driving mechanism 340 is above the second sliding portion 334a, the lower end of the second sliding portion 334a extends below the first sliding portion 333a and is connected to the second clamping portion 334b, and the second guiding hole serves to guide the sliding direction of the second clamping portion 334b, so that the second clamping arm 334 slides on the first clamping arm 333, and the output end of the second lifting driving mechanism 340 can abut against the upper end of the second sliding portion 334a.

[0059] The axial directions of both the first guiding hole 311 and the second guiding hole are the up-and-down direction. The first sliding portion 333a is perpendicular to the first clamping portion 333b, and the second sliding portion 334a is perpendicular to the second clamping portion 334b. Both the first clamping portion 333b and the second clamping portion 334b are horizontally arranged.

[0060] Referring to Figures 5 to 7, in some of these embodiments, a through hole 312 is provided at the lower end of the rotating shaft 310. Both openings of the through hole 312 are provided on the peripheral wall of the rotating shaft 310. The two ends of the first guiding hole 311 are respectively opened on the lower end surface of the rotating shaft 310 and the lower side wall of the through hole 312. The first sliding portion 333a is inserted through the first guiding hole 311, and the second sliding portion 334a is inserted through the second guiding hole, so that the main structures of the first clamping arm 333 and the second clamping arm 334 are both within the lower projection range of the rotating shaft 310, making the structure of the winding group 300 more compact. There is a larger idle space outside the rotating shaft 310, and multiple winding groups 300 can be arranged side by side.

[0061] The upper end of the second sliding portion 334a is connected to a second downward pressing portion 334c extending outside the rotating shaft 310. The output end of the second lifting and driving mechanism 340 presses down the second sliding portion 334a through the second downward pressing portion 334c, so that the second lifting and driving mechanism 340 can be arranged outside the rotating shaft 310 and can drive the second sliding portion 334a to move downward. The second lifting and driving mechanism 340 is not arranged inside the rotating shaft 310, which can avoid the increase of the structural size of the rotating shaft 310.

[0062] The upper end of the first sliding portion 333a is connected to a first downward pressing portion 333c extending outside the rotating shaft 310. The first downward pressing portion 333c is above the second downward pressing portion 334c to prevent the lifting of the second downward pressing portion 334c from affecting the first downward pressing portion 333c. The first lifting and driving mechanism 350 is arranged on the bracket 200. The output end of the first lifting and driving mechanism 350 presses down the first sliding portion 333a through the first downward pressing portion 333c. The output end of the second lifting and driving mechanism 340 is connected to that of the first lifting and driving mechanism 350. The second lifting and driving mechanism 340 simultaneously drives the first lifting and driving mechanism 350 and the first downward pressing portion 333c to move downward, that is, simultaneously drives the first lifting and driving mechanism 350, the first clamping arm 333 and the second clamping arm 334 to descend, ensuring that the first lifting and driving mechanism 350 can still act on the second downward pressing portion 334c during the lifting of the first clamping arm 333 and the second clamping arm 334, that is, the lifting of the first wire head clamp 330 and the clamping or loosening of the wire head / lead wire by the first wire head clamp 330 do not affect each other.

[0063] When multiple winding groups 300 are provided, each second downward pressing portion 334c extends to the rotating shaft 310. One second lifting and driving mechanism 340 can be provided, and the second lifting and driving mechanism 340 can simultaneously drive multiple second downward pressing portions 334c, which plays the role of saving components, reducing the equipment space and lowering the operation difficulty.

[0067] A third guide hole is provided on the first downward pressing portion 333c, and the first downward pressing portion 333c is sleeved on the guide rod 313 through the third guide hole. The guide rod 313 serves to guide the lifting of the first downward pressing portion 333c. The first downward pressing portion 333c is connected to the first sliding portion 333a in a detachable manner.

Of course, the second wire head clamp 410 can also be directly connected to the first mounting plate.
