Abstract
Description
Technical Field
[0001] This utility model relates to the field of filament production and manufacturing technology, specifically an automatic filament winding device with precise distance control. Background Technology
[0002] The production and manufacturing of lamp filaments mainly revolves around high-melting-point metals. Tungsten powder is pressed into billets and sintered into dense tungsten rods using powder metallurgy. The tungsten rods are then gradually drawn into tungsten wires with a diameter of micrometers using multi-pass drawing dies. Then, according to the design requirements of the lamp, the tungsten wires are processed into spirals or other specific shapes using a wire winding machine. After removing surface impurities and coating with electron-emitting materials, the luminous efficiency and service life are improved. Through cutting, shaping, and strict quality inspection, finished lamp filaments that meet the standards are produced, ensuring that the filaments have a uniform diameter and stable physical properties.
[0003] In the winding process of filament production, operators need to wrap the end of the filament around the winding rod once, and then manually tie a knot to secure it. When winding, it is necessary to ensure that the filament and the rod are tightly attached to each other to prevent loosening. Usually, this step is mainly done manually, which requires a high level of skill from the operators. The operating speed directly affects the overall production efficiency. In view of this, we provide an automatic filament winding device with precise distance control. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an automatic filament winding device with precise distance control.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic filament winding device for precise distance control, comprising a metal base plate, a control box mounted on the top surface of the metal base plate, multiple winding side frames and lead screw side frames fixedly connected to both sides of the top surface of the metal base plate, and a first servo motor and a second servo motor fixedly connected to one side of the outer wall of one of the winding side frames and the lead screw side frame, respectively. A winding screw is fixedly connected to the outer wall of the output end of the first servo motor, and a movable slot is provided on the top surface of the winding screw. A push plate is slidably connected to one end of the movable slot via a slide rail, and a metal wire clamp is rotatably connected to one side of the push plate via a rotating shaft. A reciprocating lead screw is fixedly connected to the output end of the second servo motor, and a reciprocating drive block is threadedly connected to the outer wall of the reciprocating lead screw. The control box is electrically connected to the first servo motor and the second servo motor.
[0006] As described above, the winding screw has an inclined groove inside, and a connecting groove is provided at the top of the inclined groove. The inclined groove is connected to the interior of the movable groove through the connecting groove, and the inclined groove has a gently upward inclined trend.
[0007] As described above, a guide member is added to the center of the bottom surface of the metal wire clip, and the guide member has a T-shaped structure. The bottom of the outer wall of the guide member extends into the interior of the inclined groove through a connecting groove, and the bottom of the outer wall of the guide member is slidably connected to the bottom of the inclined groove.
[0008] As described above, the metal wire clamp has a hook-shaped structure when viewed from the side, and there are gaps between the outer walls of both sides of the metal wire clamp and the inner walls of the movable slot.
[0009] As described above, a rotating plate is rotatably connected to the center of the reciprocating drive block, and the outer wall of the rotating plate is threadedly connected to the outer wall of the reciprocating lead screw.
[0010] As mentioned above, the outer wall of the reciprocating screw penetrates the center of the reciprocating drive block, and a threader is added to the top surface of the reciprocating drive block.
[0011] As described above, a sliding groove is provided on one side of the top surface of the metal base plate, and the reciprocating drive block is slidably connected to one side of the top surface of the metal base plate through the sliding groove.
[0012] Compared with existing technologies, this automatic filament winding device with precise distance control has the following advantages:
[0013] I. In the winding process of filament production, this utility model first inserts the filament into the threader, then gently pushes the push plate, and drives the metal wire clamp to tilt up through the inclined groove, placing the end of the filament in the hook groove at the bottom of the metal wire clamp. Then, push the push plate back, so that the barbed structure of the metal wire clamp hooks the filament, pressing the filament tightly against the inner wall of the movable groove. This eliminates the need for manual knotting. Under the action of the metal wire clamp, the end of the filament is rigidly abutted against the inner wall of the movable groove, ensuring that the filament is tightly attached to the outer wall of the winding rod, avoiding problems such as loosening caused by uneven manual winding force. At the same time, it reduces the operation threshold and improves production efficiency to a certain extent.
[0014] II. In this utility model, the electrical signal sent by the control box is transmitted to the second servo motor. The PLC module built into the control box can store multiple sets of parameters. The operator connects the computer or mobile phone to the control box with a data cable and adjusts the filament spacing during winding on the computer or mobile phone. After the first servo motor and the second servo motor start simultaneously, the second servo motor drives the reciprocating screw to move. The reciprocating screw drives the reciprocating drive block on its outer wall to make uniform reciprocating motion. Its displacement is linked with the winding speed driven by the first servo motor to ensure that the filament is wound evenly at the preset spacing.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] like Figure 1-5As shown, this utility model provides a technical solution: an automatic filament winding device for precise distance control, including a metal base plate 1, a control box 101 mounted on the top surface of the metal base plate 1, multiple winding side frames 2 and screw side frames 3 fixedly connected to both sides of the top surface of the metal base plate 1, and a first servo motor 201 and a second servo motor 301 fixedly connected to one side of the outer wall of one of the winding side frames 2 and the screw side frame 3, respectively. A winding screw 202 is fixedly connected to the outer wall of the output end of the first servo motor 201, and a movable slot 203 is opened on the top surface of the winding screw 202. A push plate 204 is slidably connected to one end of the movable slot 203 through a slide rail, and a metal wire clamp 205 is rotatably connected to one side of the push plate 204 through a rotating shaft. A reciprocating screw 302 is fixedly connected to the output end of the second servo motor 301, and a reciprocating drive block 303 is threadedly connected to the outer wall of the reciprocating screw 302. The control box 101 is electrically connected to the first servo motor 201 and the second servo motor 301.
[0026] Insert the filament into the threader 305, gently push the push plate 204, and drive the metal wire clamp 205 to tilt up through the inclined groove 206. Place the end of the filament in the hook groove at the bottom of the metal wire clamp 205, and push the push plate 204 back so that the barbed structure of the metal wire clamp 205 hooks the filament and presses the filament tightly against the inner wall of the movable groove 203. After the first servo motor 201 and the second servo motor 301 start simultaneously, the second servo motor 301 drives the reciprocating screw 302 to move. The reciprocating screw 302 drives the reciprocating drive block 303 on its outer wall to make uniform reciprocating motion. Its displacement is matched with the winding speed driven by the first servo motor 201 to ensure that the filament is wound evenly at the preset interval.
[0027] like Figures 3-4 As shown, the screw 202 has an inclined groove 206 inside, and a connecting groove 207 is provided at the top of the inclined groove 206. The inclined groove 206 is connected to the interior of the movable slot 203 through the connecting groove 207, and the inclined groove 206 has a gently upward inclined trend.
[0028] The inclined groove 206 is connected to the movable groove 203 via the connecting groove 207, providing a basis for the subsequent smooth movement of the guide component 208 along the preset trajectory.
[0029] like Figures 3-4 As shown, a guide member 208 is added to the center of the bottom surface of the metal wire clip 205, and the guide member 208 has a T-shaped structure. The bottom of the outer wall of the guide member 208 extends into the interior of the inclined groove 206 through the connecting groove 207, and the bottom of the outer wall of the guide member 208 is slidably connected to the bottom of the inclined groove 206.
[0030] The guide member 208 has an inverted T-shaped structure and extends into the inclined groove 206 to slide, providing stable guidance for the metal wire clamp 205. This ensures that after one end of the metal wire clamp 205 is pushed forward by the push plate 204, it will be lifted up on the basis of the inclined groove 206, so that the filament can be placed in the hook groove below it.
[0031] like Figures 3-4 As shown, the metal wire clip 205 has a hook-shaped structure when viewed from the side, and there are gaps between the outer walls of both sides of the metal wire clip 205 and the inner walls of the movable slot 203.
[0032] The metal wire clip 205 has a barbed side structure that can effectively hook the filament for quick fixation. The gap between the outer walls on both sides and the inner wall of the movable slot 203 not only preserves space to accommodate the filament and prevents it from being squeezed and damaged, but also achieves a fixing effect through abutment and friction.
[0033] like Figures 1-2 As shown, a rotating plate 304 is rotatably connected to the center of the reciprocating drive block 303, and the outer wall of the rotating plate 304 is threadedly connected to the outer wall of the reciprocating lead screw 302.
[0034] The internal rotating plate 304 of the reciprocating drive block 303 is threadedly connected to the reciprocating lead screw 302, converting the rotation of the reciprocating lead screw 302 into linear reciprocating motion.
[0035] like Figures 1-2 As shown, the outer wall of the reciprocating lead screw 302 penetrates the center of the reciprocating drive block 303, and a wire threader 305 is added to the top surface of the reciprocating drive block 303.
[0036] The threader 305 is integrated on the top surface of the reciprocating drive block 303 and can move synchronously with the drive block.
[0037] like Figure 1 As shown, a groove 306 is provided on one side of the top surface of the metal base plate 1, and the reciprocating drive block 303 is slidably connected to one side of the top surface of the metal base plate 1 through the groove 306.
[0038] The reciprocating drive block 303 is slidably connected to the metal base plate 1 through the slide groove 306, which constrains the movement trajectory of the reciprocating drive block 303.
[0039] Working principle: After the operator starts the equipment, first insert the end of the filament to be wound into the guide hole of the threader 305, so that the filament passes smoothly through the inner wall of the threader 305. Then, gently push the push plate 204 located on the top surface of the winding rod 202. Through the contact between the inclined groove 206 at the bottom of the push plate 204 and the guide member 208, the metal wire clamp 205 is driven to tilt upwards at the end away from the push plate 204, so that the hook groove at its bottom is fully exposed. The operator places the end of the filament and completely passes it through the hook groove, and pulls the push plate 204 back. The metal wire clamp 205 is reset under the guidance of the inner wall of the inclined groove 206, and its end barb... The structure hooks the filament and presses it tightly into the inner wall of the movable slot 203 to achieve fixation. When it is necessary to change the winding spacing, the operator connects the computer to the control box 101 via a data cable, changes the winding spacing of the device in the supporting software, and after the start operation command is given, the first servo motor 201 drives the winding rod 202 to rotate, while the second servo motor 301 drives the reciprocating rod 302 to rotate synchronously. The reciprocating drive block 303 on its outer wall makes uniform reciprocating motion along the axial direction through thread transmission, causing the filament to form a spiral arrangement on the surface of the winding rod 202 until the set length is reached and the equipment stops.
[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
