[0001] This invention belongs to the field of winding machine technology, specifically a semi-automatic winding machine for miniature coils. Background Technology

[0002] The advent of winding machines replaced manual winding, significantly improving the technology and performance of manufactured products, and their industrial applications are widespread. In the field of electromechanical engineering, winding machines are commonly used for coil winding; for motor coil winding, they reduce uneven tension and insulation damage problems associated with manual winding, thus improving transformer manufacturing processes. Currently, winding machines are mainly used for winding coils in AC motors, DC motors, clutches, and other electrical appliances, and are important specialized equipment in the electronics industry. With the rapid development of the electronics and electrical appliance industry, the demand for coils is increasing, the variety is growing, and the requirements are becoming more stringent.

[0003] Currently, the production of motor and clutch coils is carried out using mechanical equipment. Although some of these machines are highly efficient, their internal structures are complex, and they cannot keep up with sudden changes in tension, leading to short circuits when winding miniature coils.

[0011] A limiting component is installed on the top of the movable seat near the winding mechanism, and two limiting components are provided;

[0012] A wiping assembly is mounted on the top of the movable base on the side near the electronic screen.

[0013] Furthermore, the feeding mechanism also includes:

[0014] A metal wire, the outer wall of which contacts the inner wall of the limiting component, and the outer wall of the metal wire is sleeved with the inner wall of the wiping component.

[0024] A limiting rod is symmetrically arranged on opposite sides of the drive block, and the outer wall of the limiting rod is sleeved with the inner wall of the feeding mechanism;

[0025] The screw has two ends that are rotatably connected to the opposite side of the drive block, and the outer wall of the screw is threadedly connected to the inner wall of the feeding mechanism.

[0026] Furthermore, the winding mechanism includes:

[0027] A mounting bracket, which is installed on the top of the machine base.

[0028] The slider is symmetrically arranged on the inner wall of the fixed frame, the outer wall of the slider is slidably connected to the inner wall of the fixed frame, and the inner wall of the slider is engaged with the outer wall of the support rod.

[0029] The motor is mounted on the side of the mounting bracket away from the slider;

[0030] The second wire frame has one end rotatably connected to the outer wall of the motor.

[0031] Furthermore, the limiting component includes:

[0032] The telescopic column is symmetrically arranged on the top of the moving block. The telescopic column drives two sets of limit wheels to move in opposite directions up and down, so as to finely adjust the distance between the two limit wheels, thereby finely adjusting the tension of the metal wire.

[0033] The frame, the bottom of which is mounted on top of the telescopic column;

[0035] Furthermore, the limiting component also includes:

[0036] A rotating rod is symmetrically arranged on the outer wall of the limiting wheel, and the outer wall of the rotating rod is rotatably connected to the outer wall of the limiting wheel;

[0037] The bent rod has two ends that are rotatably connected to the opposite side of the rotating rod. The bent rod is elastic, so that the metal wire is pressed close to the limiting wheel, making the metal wire fit tightly against the limiting wheel, which facilitates the control of the movement direction of the metal wire.

[0038] A collar, the inner wall of which is fitted onto the outer wall of the bent rod, and the outer wall of the collar is in contact with the outer wall of the metal wire. The collar is made of rubber and rotates with the metal wire as it passes through.

[0039] Furthermore, the wiping assembly includes:

[0040] Elastic rods are evenly distributed on the inner wall of the top of the moving block, and the elastic rods are made of elastic rubber.

[0041] A tube body, wherein the tube body is installed at one end of an elastic rod, and a fixing plate is installed at the end of the tube body away from the elastic rod;

[0046] The beneficial effects of this invention are as follows:

[0047] 1. By setting up a feeding mechanism, the metal wire is cleaned on the surface by a wiping component during the winding process, and the bent parts of the metal wire are straightened. Keeping the metal wire in a straight state during winding can reduce the metal wire from getting tangled or loose during the winding process. The limiting component helps to adjust the tension of the metal wire to avoid the metal wire being too tight and breaking, which would affect the winding efficiency.

[0048] 2. The present invention, by setting up a winding mechanism, allows the motor to drive the second wire frame to rotate during winding, so that the metal wire is wound around the surface of the second wire frame. During the winding process, the slider moves up and down on the fixed frame, which can initially adjust the tightness of the metal wire, and then make fine adjustments during winding to keep the metal wire taut but not broken.

[0049] 3. By setting a limiting component, the limiting wheel does not rotate during operation, allowing the metal wire to slide across the surface of the limiting wheel. The metal wire passes through the groove of the limiting wheel and is limited. This controls the metal wire to remain perpendicular to the second wire frame during the reciprocating movement of the moving block, reducing the bending path of the metal wire, reducing friction of the metal wire, avoiding the need for the metal wire to derail and be re-wired, and maintaining the stability of the equipment operation.

[0050] 4. This invention, by setting up a wiping assembly, allows workers to press down with a pressing block, causing the rod to insert into the arc-shaped piece, bringing the wiping pieces at the bottom of the spring closer together, so that the wiping pieces close, allowing the metal wire to pass through the gaps in the wiping pieces, so that the wiping pieces wipe the metal wire, and through the compression of the rod and the spring, the metal wire is stretched to a certain extent as it passes through, avoiding the metal wire being too loose due to excessive tension, thus reducing the metal wire from getting tangled.

Detailed Implementation

[0060] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0061] Example 1, please refer to Figures 1-5 The present invention provides a technical solution: a semi-automatic winding machine for miniature coils is described below.

[0062] include:

[0063] Machine 1, with an electronic screen 2 installed on its top;

[0064] The moving mechanism 3 is installed on the top of the machine base 1;

[0065] The inner wall of the feeding mechanism 4 is threadedly connected to the outer wall of the moving mechanism 3.

[0066] The winding mechanism 5 is installed on the top of the machine base 1, and the inner wall of the winding mechanism 5 is engaged with the outer wall of the moving mechanism 3.

[0067] During operation, the metal wire 403 is passed from the moving mechanism 3 through the feeding mechanism 4 and connected to the winding mechanism 5. Then, the parameters are set on the electronic screen 2, and the winding mechanism 5 is turned on to wind the metal wire 403. The moving mechanism 3 and the feeding mechanism 4 clean the surface of the metal wire 403 and adjust the tension of the metal wire 403 so that the metal wire 403 can be kept straight during winding, so that the coil can be wound tightly and evenly. After the winding is completed, the worker removes the coil and places a new empty coil on the winding mechanism 5, and repeats the above operation.

[0068] The feeding mechanism 4 includes:

[0069] The movable seat 401 has its inner wall fitted into the outer wall of the movable mechanism 3.

[0070] Limiting component 404 is installed on the top of the movable base 401 near the winding mechanism 5, and two limiting components 404 are provided;

[0071] Wiping assembly 405 is installed on the top of the movable base 401 on the side near the electronic screen 2.

[0072] The feeding mechanism 4 also includes:

[0073] Metal wire 403, the outer wall of metal wire 403 contacts the inner wall of limiting component 404, and the outer wall of metal wire 403 is sleeved with the inner wall of wiping component 405.

[0074] The support wheel 402 is installed on the side of the movable base 401 near the electronic screen 2. The outer wall of the support wheel 402 is in contact with the outer wall of the metal wire 403. The support wheel 402 enables the metal wire 403 to be in a smooth state when turning, avoiding the metal wire 403 from contacting the edge of the movable base 401, which would cause friction and make the metal wire 403 wear and break easily.

[0075] When the winding mechanism 5 is working, the metal wire 403 rests on the support wheel 402, then passes through the wiping component 405 on the moving seat 401, and exits through the limiting component 404. During the winding process, the surface of the metal wire 403 is cleaned by the wiping component 405, and the bent parts of the metal wire 403 are straightened. Keeping the metal wire 403 straight during winding can reduce the metal wire 403 from getting tangled or loose during the winding process. The limiting component 404 helps to adjust the tension of the metal wire 403 to prevent the metal wire 403 from being too tight and breaking, which would affect the winding efficiency.

[0076] Mobile mechanism 3 includes:

[0077] Drive block 305, drive block 305 is symmetrically arranged above machine base 1;

[0078] Support rod 302, the support rod 302 is symmetrically arranged on the opposite side of the drive block 305;

[0079] The buffer columns 301 are evenly distributed on the top of the machine base 1, and the bottom of the support rod 302 is in contact with the top of the buffer columns 301.

[0080] The mobile mechanism 3 also includes:

[0081] The bottom of the carriage 303 is slidably connected to the top of the support rod 302;

[0082] The first wire frame 304 is installed on the top of the slide 303. The outer wall of the first wire frame 304 is connected to one end of the metal wire 403. The outer wall of the first wire frame 304 is rotatably connected to the outer wall of the slide 303.

[0083] The mobile mechanism 3 also includes:

[0084] Limiting rod 306 is symmetrically arranged on the opposite side of drive block 305, and the outer wall of limiting rod 306 is sleeved with the inner wall of feeding mechanism 4.

[0085] The screw 307 has two ends that are rotatably connected to the opposite side of the drive block 305, and the outer wall of the screw 307 is threadedly connected to the inner wall of the feeding mechanism 4.

[0086] During winding, the drive block 305 drives the screw 307 to rotate, causing the feeding mechanism 4 to move back and forth on the limit rod 306. At the same time, the slide 303 drives the first wire frame 304 to move back and forth, thereby cooperating with the winding mechanism 5 to move back and forth, so that the metal wire 403 on the first wire frame 304 is wound evenly and sequentially onto the second wire frame 504, in conjunction with different types of coils for winding.

[0087] The winding mechanism 5 includes:

[0088] Mounting bracket 501 is installed on the top of machine base 1.

[0089] Slider 502 is symmetrically arranged on the inner wall of the fixed frame 501. The outer wall of slider 502 is slidably connected to the inner wall of the fixed frame 501. The inner wall of slider 502 is engaged with the outer wall of support rod 302.

[0090] Motor 503 is mounted on the side of the fixed frame 501 away from the slider 502;

[0091] The second wire frame 504 has one end rotatably connected to the outer wall of the motor 503.

[0092] During the winding process, the motor 503 drives the second wire frame 504 to rotate, causing the metal wire 403 to wrap around the surface of the second wire frame 504. During the winding process, the slider 502 moves up and down on the fixed frame 501, which can initially adjust the tension of the metal wire 403, and then make fine adjustments during the winding process to keep the metal wire 403 taut but not broken.

[0093] Example 2, please refer to Figures 1-8 The present invention provides a technical solution: based on embodiment 1, the limiting component 404 includes:

[0094] Telescopic column 4041 is symmetrically arranged on the top of the moving block. The telescopic column 4041 drives two sets of limit wheels 4043 to move in opposite directions up and down, so that the distance between the two limit wheels 4043 can be finely adjusted, thereby finely adjusting the tension of the metal wire 403.

[0095] The frame 4042 has its bottom installed on top of the telescopic column 4041;

[0096] The limiting wheel 4043 has its outer wall rotatably connected to the opposite side of the frame 4042. The limiting wheel 4043 is made of a material with low friction.

[0097] Limiting component 404 also includes:

[0098] Rotating rod 4044 is symmetrically arranged on the outer wall of limiting wheel 4043, and the outer wall of rotating rod 4044 is rotatably connected to the outer wall of limiting wheel 4043;

[0099] The bent rod 4045 has two ends that are rotatably connected to the opposite side of the rotating rod 4044. The bent rod 4045 is elastic, so that the metal wire 403 is pressed close to the limiting wheel 4043, so that the metal wire 403 is in close contact with the limiting wheel 4043, which makes it easier to control the movement direction of the metal wire 403.

[0100] The inner wall of the collar 4046 is fitted with the outer wall of the bent rod 4045, and the outer wall of the collar 4046 is in contact with the outer wall of the metal wire 403. The collar 4046 is made of rubber and rotates with the metal wire 403 as it passes through.

[0101] Metal wires 403 are interlaced and threaded through the brackets of two limit wheels 4043. During operation, the limit wheels 4043 do not rotate, allowing the metal wires 403 to slide across the surface of the limit wheels 4043. The metal wires 403 pass through the grooves of the limit wheels 4043, controlling the metal wires 403 to remain perpendicular to the second wire frame 504 during the reciprocating movement of the moving block. This reduces the bending path of the metal wires 403, reduces friction of the metal wires 403, and prevents the metal wires 403 from derailing and needing to be re-wired, thus maintaining the stability of the equipment operation.

[0102] Wiping assembly 405 includes:

[0103] Elastic rod 4053 is evenly distributed on the inner wall of the top of the moving block. The elastic rod 4053 is made of elastic rubber.

[0104] The tube body 4051 is installed at one end of the elastic rod 4053, and a fixing plate 4052 is installed at the end of the tube body 4051 away from the elastic rod 4053.

[0105] Arc-shaped pieces 4054 are evenly distributed on the outer wall of the fixed disk 4052.

[0106] The wiping assembly 405 also includes:

[0107] The rod body 4055 has its outer wall engaged with the inner wall of the arc-shaped piece 4054. A pressing block 4056 is installed on the outer wall of the rod body 4055, and a spring 4057 is installed at the end of the rod body 4055 away from the pressing block 4056.

[0108] Wiping pad 4058, the outer wall of wiping pad 4058 is connected to the bottom of spring 4057, the inner wall of wiping pad 4058 is connected to the outer wall of metal wire 403, and the material of wiping pad 4058 is a flexible cleaning material.

[0109] During winding, the metal wire 403 is passed through the tube 4051 and the fixing plate 4052. The worker presses down with the pressing block 4056, causing the rod 4055 to insert into the arc-shaped piece 4054. The wiping pieces 4058 at the bottom of the spring 4057 are brought closer together, causing the wiping pieces 4058 to close. The metal wire 403 passes through the gap of the wiping pieces 4058, allowing the wiping pieces 4058 to wipe the metal wire 403. Through the compression of the rod 4055 and the spring 4057, the metal wire 403 is stretched to a certain extent as it passes through, preventing the tension of the metal wire 403 from being too loose and causing it to become too loose during winding, thus reducing the knotting of the metal wire 403.

[0110] The specific workflow is as follows:

[0111] During operation, the metal wire 403 is passed from the moving mechanism 3 through the feeding mechanism 4 and connected to the winding mechanism 5. Then, the parameters are set on the electronic screen 2. During winding, the motor 503 drives the second wire frame 504 to rotate, so that the metal wire 403 is wound around the surface of the second wire frame 504. During the winding process, the slider 502 moves up and down on the fixed frame 501, which can initially adjust the tightness of the metal wire 403, and then make fine adjustments during winding to keep the metal wire 403 taut but not broken. The drive block 305 drives the screw 307 to rotate, so that the feeding mechanism 4 moves back and forth on the limit rod 306. At the same time, the slide 303 drives the first wire frame 304 to move back and forth, so as to cooperate with the reciprocating movement of the winding mechanism 5 to wind the metal wire 403 on the first wire frame 304 evenly and sequentially onto the second wire frame 504, and to carry out winding work with different types of coils.

[0112] When the winding mechanism 5 is working, the metal wire 403 rests on the support wheel 402, and then passes through the tube 4051 and the fixed plate 4052. The worker presses down by pressing the pressing block 4056, so that the rod 4055 is inserted into the arc-shaped plate 4054, and the wiping plates 4058 at the bottom of the spring 4057 are brought closer to each other, so that the wiping plates 4058 are closed, and the metal wire 403 passes through the gap of the wiping plates 4058, so that the wiping plates 4058 wipe the metal wire 403. Through the compression of the rod 4055 and the spring 4057, the metal wire 403 is stretched to a certain extent when passing through.

[0113] Metal wires 403 are interlaced and threaded through the brackets of two limit wheels 4043. During operation, the limit wheels 4043 do not rotate, allowing the metal wires 403 to slide across the surface of the limit wheels 4043. The metal wires 403 pass through the grooves of the limit wheels 4043, controlling the metal wires 403 to remain perpendicular to the second wire frame 504 during the reciprocating movement of the moving block. This reduces the bending path of the metal wires 403, reduces the friction of the metal wires 403, and prevents the metal wires 403 from derailing and needing to be re-wired, thus maintaining the stability of the equipment operation.

[0114] After the winding is completed, the worker removes the coil and places a new empty coil on the winding mechanism 5, repeating the above operation.

[0115] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
