Technical Field
[0001] This utility model relates to the field of auxiliary technology for winding wires in special heating lamps, and in particular to a coreless winding machine for special heating lamps. Background Technology
[0002] Specialty heating lamps are indispensable key components in manufacturing equipment used in industries such as photovoltaics, food processing, chip manufacturing, textiles, automotive painting, and outdoor heating. The filament is the most crucial component of the heating lamp. Traditional filament winding machines require an iron core rod for winding the tungsten filament. After winding, the iron core rod in the middle of the tungsten filament needs to be etched away with strong acid to obtain the tungsten filament.
[0003] Coreless winding machines evolved from traditional winding machines. With the continuous advancement of manufacturing, traditional winding machines have gradually become unable to meet the demands for high-precision and high-efficiency production. Therefore, coreless winding machines emerged and, with their unique advantages, have secured a place in the market.
[0004] Existing filament winding machines for special heating lamps suffer from high costs and complex processes. Therefore, it is particularly important to design a coreless filament winding machine for special heating lamps to solve the above-mentioned technical problems. Utility Model Content
[0005] The purpose of this invention is to solve the problem that existing winding machines for special-purpose lamps are costly and have complex processes, and to propose a coreless winding machine for special heating lamps.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a coreless wire winding machine for special heating lamps, comprising a work frame, a wire spool frame mounted on the work frame, a tungsten wire spool mounted on the wire spool frame, linear guide rails symmetrically arranged below the wire spool frame on the work frame, a wire feeding rightward origin sensor mounted on one side of the linear guide rail on the work frame, a rack mounted on the linear guide rail, the wire spool frame slidably mounted on the linear guide rail, a tungsten wire heating tube mounted on the wire spool frame, and a wire feeding mechanism located behind the tungsten wire heating tube on the wire spool frame. The cylinder has a wire feeding seat on the front side of the tungsten wire heating tube, a wire clamping cylinder on the wire feeding seat, a wire guide nozzle on the wire feeding seat, a right mandrel moving support guide wheel on the left side of the wire guide nozzle, a wire fixing block on the right side of the wire feeding seat, a wire feeding right-moving servo motor on the wire spool frame, a slide rail below the wire feeding seat, a right-winding pneumatic rotating clamp slidably mounted on the slide rail, a touch screen on the work frame on the left side of the linear guide rail, and a spring steel mandrel movably mounted in the right-winding pneumatic rotating clamp.
[0007] Preferably, a cutter holder is installed on the left side of the right-hand pneumatic rotating clamp, and a cutter cylinder is also installed on the cutter holder.
[0008] Preferably, a left-moving linear guide helical rack is installed on the work frame on one side of the touch screen. A left-winding wire holder is slidably disposed in the left-moving linear guide helical rack. A left-winding servo motor is installed on the left side of the left-winding wire holder. A left-winding left-moving servo motor is also installed on one side of the left-winding wire holder. A left wire guard is installed on one side of the work frame of the left-winding wire holder. A right wire guard is also installed on the work frame of the right-winding pneumatic rotary clamp. A right-winding servo motor is installed on the right-winding pneumatic rotary clamp. A right-winding right-moving servo motor is also installed on the right-winding pneumatic rotary clamp.
[0009] Preferably, both the left and right wire guard seats are equipped with U-shaped support rods.
[0010] Preferably, a left-moving mandrel tensioning seat is provided on one side of the left-moving linear guide rail, a middle winding wire seat is installed on the right side of the left-moving mandrel tensioning seat, a middle winding wire hooking cylinder is inserted through the middle winding wire seat, a middle winding servo motor is installed on the top of the middle winding wire seat, a middle winding wire hooking clamp is installed on the movable end of the middle winding wire hooking cylinder, a left-moving mandrel pressing cylinder is installed in the left-moving mandrel tensioning seat, and a left-moving mandrel finger clamping cylinder is installed on the right side of the left-moving mandrel pressing cylinder.
[0011] Preferably, a left-shift origin sensor is installed at the left end of the left-shift linear guide helical rack.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] 1. In this utility model, during use, the components used for displacement in the overall structure of this utility model are all selected from 6-level precision ground helical gears and racks. Compared with other wire winding machines on the market that use ball screw transmission, this model maximizes work efficiency while meeting the requirements for wire winding pitch accuracy and travel accuracy. The wire winding speed and efficiency are 2-3 times that of these machines. It is also more stable and easier to maintain. The heating of the thick wire is achieved using a ring heating tube device and temperature controller. This invention produces no open flame, making it safer than similar devices that use open flame heating in a vaporization furnace. The temperature can be displayed and adjusted in real time. When winding double-filament products (two tungsten wires in the same direction, wound with the same pitch length on the same mandrel), it employs dual-channel independent wire clamping for more stable wire feeding. During the leftward movement of the core puller, a reverse winding action is added to create a loosening effect, avoiding the uneven pitch at the wire head and tail that occurs in similar equipment when winding long filaments. The technical solution adopted in this invention enables semi-automated production of coreless filament winding for heating lamps. The overall structure is compact and easy to install and maintain, solving the problems of high cost and complex processes associated with existing filament winding machines used for special heating lamps.
[0014] 2. In this utility model, during use, the left winding and left shifting servo motor rotates, the left winding wire seat moves to the right, and the left shifting mandrel tensioning seat moves to the right simultaneously under the drive of the spring. The U-shaped wire support rod on the corresponding drive cylinder on the left wire guard seat descends in sequence. When the left winding wire seat reaches the point where it passes through the middle winding wire seat and then through the collet hole in the right winding pneumatic rotating clamp, after a delay of 0.4 seconds, the cylinder behind the right winding pneumatic rotating clamp is activated to clamp the mandrel. The left core pressing cylinder on the left tensioning seat rises and releases the steel wire. At the same time, the left mandrel clamping finger cylinder opens. After the steel wire is released, the left and right winding wire seat moving motors move synchronously to the right under the drive of the helical gear and rack on the motor. After reaching the set distance, the right winding and right shifting motor moves to the right again by a distance (the distance can be set on the touch screen). Under the clamping of the right winding pneumatic rotating clamp, the steel mandrel is tightened. Attached Figure Description

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0021] This utility model provides a coreless wire winding machine for special heating lamps, including a work frame 1. A wire spool frame 101 is mounted on the work frame 1, and a tungsten wire spool 102 is mounted on the wire spool frame 101. Linear guide rails 2 are symmetrically arranged below the wire spool frame 101 on the work frame 1. A wire feeding rightward origin sensor 201 is mounted on one side of the linear guide rail 2 on the work frame 1. A rack 202 is also mounted on the linear guide rail 2. The wire spool frame 101 is slidably mounted on the linear guide rail 2, and a tungsten wire heating element is mounted on the wire spool frame 101. The tungsten wire heating tube 3 has a wire feeding cylinder 301 mounted on the rear side of the wire spool frame 101, and a wire feeding seat 302 mounted on the front side of the tungsten wire heating tube 3. A wire clamping cylinder 303 is mounted on the wire feeding seat 302, and a wire guide nozzle 304 is also mounted on the wire feeding seat 302. A right mandrel moving support guide wheel 4 is mounted on the left side of the wire guide nozzle 304, and a wire fixing block 401 is mounted on the right side of the wire guide nozzle 304 on the wire feeding seat 302. A right-moving wire feeding servo motor 103 is also mounted on the wire spool frame 101. A slide rail 104 is provided below the wire feeder 302. A right-winding pneumatic rotary clamp 105 is slidably mounted on the slide rail 104. A touch screen 5 is mounted on the work frame 1 on the left side of the linear guide 2. A spring steel core rod 501 is movably mounted in the right-winding pneumatic rotary clamp 105. A left-moving linear guide 2 helical rack 202 is mounted on the work frame 1 on one side of the touch screen 5. A left-winding wire holder 601 is slidably mounted in the left-moving linear guide 2 helical rack 202. A left-winding servo motor 6 is mounted on the left side of the left-winding wire holder 601. 02. A left-winding and left-moving servo motor 603 is also installed on one side of the left-winding wire holder 601. A left wire guard 604 is installed on one side of the work frame 1 of the left-winding wire holder 601. A right wire guard 605 is also installed on the work frame 1 of the right-winding pneumatic rotary clamp 105. U-shaped support rods 606 are installed on both the left wire guard 604 and the right wire guard 605. A right-winding servo motor 801 is installed on the right-winding pneumatic rotary clamp 105. A right-winding and right-moving servo motor 802 is also installed on the right-winding pneumatic rotary clamp 105.
[0022] In actual use, the coreless filament winding machine for special heating lamps first mounts the tungsten filament spool 102 on the filament spool holder 101. The tungsten filament passes through the tungsten filament heating tube 3, and the heating temperature is controlled by a temperature controller, which displays the temperature in real time. The filament then passes through the guide nozzle 304 and is clamped by the filament feeding cylinder 301 and the clamping cylinder 303. One end of the spring steel core rod 501 passes through the middle guide nozzle 304 and is locked onto the left winding clamp. The left filament protection switch is activated on the touchscreen 5. The U-shaped filament protection support rod rises under the action of the corresponding filament protection seat, lifting the spring steel core rod 501. The left-shifting core rod tensioning seat 7 is slidable and can be manually moved to the leftmost position. The left-shifting core rod tensioning seat 7 contains a spring structure. Under the action of external auxiliary force, the spring is compressed. The left pressing core cylinder descends to press the steel wire, and the left core rod clamping finger cylinder simultaneously clamps the steel wire. After checking that all sensors and servo motors have reset, the filament parameters are set, and then the start button is pressed.
[0023] The left-winding and left-shifting servo motor 603 rotates, the left-winding wire seat 601 moves to the right, and the left-shifting mandrel tensioning seat 7 moves to the right simultaneously under the drive of the spring. The U-shaped wire protection support rods on the corresponding drive cylinders on the left wire protection seat 604 descend sequentially. The left-winding wire seat 601 moves to the point where the mandrel passes through the middle winding wire seat 701 and then into the collet hole in the right-winding pneumatic rotating clamp 105. After a delay of 0.4 seconds, the cylinder behind the right-winding pneumatic rotating clamp 105 actuates, clamping the mandrel, and the left pressure on the left tensioning seat... The core cylinder rises, releasing the steel wire. Simultaneously, the left core rod clamping finger cylinder opens. After releasing the steel wire, the left and right winding wire seat moving motors, driven by the rotation of the helical gears and the rack 202, move synchronously to the right. After reaching the set distance, the right winding right-moving motor moves separately to the right for a distance (the distance can be set on the touchscreen). Under the clamping of the right winding pneumatic rotating clamp 105, the steel core rod is tightened. The wire feeding cylinder 301 actuates, feeding the tungsten wire forward. The middle winding wire hook cylinder... Action 702 uses a wire hook clamp to hook the tungsten wire to the left. The wire-clamping cylinder 303 on the wire feeder 302 releases, and the wire feeder 302 moves a pre-positioned distance to the right. Simultaneously, the left, center, and right winding motors start winding. At the same time, the right-moving motor of the wire feeder 302 drives the helical gear to move synchronously to the right, arranging the thread pitch. After winding to a certain distance (the distance at which the center winding nozzle does not touch the wire feed nozzle, which can be set on the touchscreen), the right mandrel moving support guide wheel 4 extends, and the support guide wheel supports the mandrel, connecting with the guide... The fixed wire support block 401 on the right side of the wire nozzle 304 supports the winding core rod together to maintain stability. The right U-shaped wire protection support rod rises sequentially from the left side of the wire feeder 302 to support the filament. When the set filament length is reached, the cylinder of the wire feeder 302 retracts, and the wire clamping cylinder 303 on the wire feeder 302 clamps the tungsten wire. The cylinder of the right core rod moving support guide wheel 4 retracts, and the cutting cylinder 503 cuts the tungsten wire. The cylinder of the right winding pneumatic rotating clamp 105 releases the core rod. The left winding left movement motor drives the left winding seat 601 to move quickly to the left through the helical gear on the motor to pull the core. At the same time, the middle winding motor reverses (the number of reverse turns is set on the touch screen) to prevent uneven thread pitch. The left mandrel clamping finger cylinder simultaneously clamps the steel wire, keeping the mandrel taut and preventing it from drooping as it moves to the left. When it is 100 mm from the end point of the left movement, the left tensioning seat's left pressure cylinder descends, applying force again to tighten the steel wire. The spring returns to its tightest compressed state. After the left-winding, left-moving motor has traveled a certain distance, the wire-feeding right-moving motor drives the helical gear to begin rapidly moving back to the origin. After traveling a certain distance, the right-winding, right-moving motor also begins rapidly moving back to the origin to reset. Finally, all motors and cylinders return to their original positions. During this process, the left and right wire-protecting seats' 605 cylinder U-shaped wire-protecting support rods rise and fall sequentially. The left wire protector rises to support the steel wire, completing one cycle. Selectable point-to-point linkage allows for continuous operation.The components used for displacement in the overall structure of this utility model are all precision-ground helical gears with a grade 6 precision and racks of 202. Compared with other wire winding machines on the market that use ball screw drives, this design maximizes work efficiency while meeting the requirements for wire winding pitch accuracy and travel accuracy. The wire winding speed and efficiency are 2-3 times higher than those of others, and it is also more stable and easier to maintain. A ring heating tube device with temperature control is used for heating the thick wire. No open flame is generated, which is safer than similar machines that use open flame heating in a vapor furnace. Moreover, the temperature can be displayed and adjusted in real time. When winding double-wire products (two tungsten wires in the same direction, wound on the same mandrel with the same pitch length), a dual-channel independent wire clamping method is used, which makes the wire feeding more stable. When the mandrel is pulled to the left, a reverse winding action is added to produce a loosening effect, avoiding the uneven pitch at the wire head and tail that occurs when winding long filaments in similar machines. The technical solution adopted by this utility model can realize semi-automatic production of coreless wire winding for heating lamps. The overall structure is compact and easy to install and maintain.

A winding wire hooking cylinder 702 is inserted through the winding wire seat 701. A winding servo motor 703 is installed on the top of the winding wire seat 701. A winding wire hooking clamp 704 is installed on the movable end of the winding wire hooking cylinder 702. A left-moving mandrel pressing cylinder 705 is installed in the left-moving mandrel tensioning seat 7. A left-moving mandrel clamping finger cylinder 706 is installed on the right side of the left-moving mandrel pressing cylinder 705. A left-moving origin sensor 8 is installed on the left end of the left-moving linear guide 2 helical rack 202.
[0026] The overall effect of Embodiment 1 is as follows: during use, the left-winding left-shifting servo motor 603 rotates, the left-winding wire seat 601 moves to the right, and the left-shifting mandrel tensioning seat 7 moves to the right simultaneously under the drive of the spring. The U-shaped wire protection support rods on the corresponding drive cylinders on the left wire protection seat 604 descend sequentially. The left-winding wire seat 601 moves to the point where the mandrel passes through the middle-winding wire seat 701 and then into the collet hole in the right-winding pneumatic rotating clamp 105. After a delay of 0.4 seconds, the right-winding pneumatic rotating clamp 105... After cylinder 05, the core rod is clamped, the left core pressing cylinder on the left tensioning seat rises, the steel wire is released, and the left core rod clamping finger cylinder opens at the same time. After the steel wire is released, the left and right winding seat moving motors move synchronously to the right under the rotation of the helical gear on the motor and the drive of the rack 202. After reaching the set distance, the right winding right moving motor moves to the right again by a distance (the distance can be set on the touch screen). Under the clamping of the right winding pneumatic rotating clamp 105, the steel core rod is tightened.
