Description

Technical Field

[0001] This invention belongs to the field of light bulb manufacturing technology, and more specifically, it relates to a cutting and transferring device for resistance wires used in the production of light bulb wicks. Background Technology

[0002] In the manufacturing process of light bulb wicks, the precise cutting and efficient transfer of the resistance wire are crucial steps to ensure smooth production and product quality. Resistance wires are typically made of high-resistivity materials, such as tungsten, molybdenum, or their alloys. These materials possess good high-temperature resistance and suitable electrical properties, making them suitable for manufacturing the electrode components inside light bulbs. Figure 1 As shown, the structure of the resistance wire is generally slender and has a certain rigidity. Its basic configuration includes a middle resistance section 100 and two end wire sections 200. The resistance section 100 is used to realize the heating function of the filament, while the two end wires 200 are used to connect to the external circuit and be fixed on the core column.

[0003] In actual production processes, such as Figure 2 As shown, multiple resistance wires are typically connected to a continuous braided tape 300 (such as nickel or copper tape) at both ends to form a continuous strip for automated feeding and processing. Subsequently, according to process requirements, individual resistance wires must be precisely cut from this tape and transported at a specific spatial angle (such as tilted or flipped) to the bulb's horn tube or other tube for subsequent assembly. This process places high demands on the accuracy of the cutting position, the reliability of the separation, and the attitude control during transport.

[0004] However, traditional methods of cutting and transferring resistance wires often rely on manual operation or semi-automatic mechanical devices, resulting in problems such as low efficiency, inaccurate positioning, and inconsistent angle control. In particular, when cutting resistance wires from the tape, incomplete cutting, damage to the wire or resistance section is prone to occur. At the same time, in the process of transporting the cut resistance wires to the horn tube, existing equipment struggles to automate the control of its input angle and spatial orientation, leading to assembly difficulties, reduced yield, and even affecting the luminous performance and lifespan of the bulb. Summary of the Invention

[0009] Furthermore, the cutting assembly includes rotating seats fixedly installed on the inner end of the conveying platform and arranged opposite each other; a third drive shaft that rotatably passes through both rotating seats, with two sets of cutting blades sleeved on the third drive shaft, the cutting blades being located above the cutting conveying cavity; a hollow sleeve fixedly installed on the base, with a sliding rod slidably installed inside the hollow sleeve, and a limit ring installed on the sliding rod; a force-increasing spring installed between the limit ring and the end of the hollow sleeve; a first connecting rod fixedly installed between the two sliding rods, with two limit ring sets sleeved on the first connecting rod; a swing cam that can overlap with the gap in the middle of the limit ring sets, and under the action of the swing cam, the first connecting rod drives the sliding rod to move downward; and a first connecting arm sleeved on the end of the third drive shaft, the other end of the first connecting arm being hinged to the upper end of the sliding rod.

[0010] Furthermore, the conveying bracket includes two parallel strips, one of which is fixedly connected to the middle of a first drive shaft; a second connecting rod is arranged parallel between the two strips; a conveying tooth is sleeved on the second connecting rod, and a counterweight is integrally provided at the bottom of the conveying tooth; the conveying tooth extends from the cut-out conveying cavity.

[0011] Furthermore, the clamping and flipping mechanism includes a support frame, fixedly mounted on a base; a first cylinder is mounted on the support frame, and a second cylinder is longitudinally mounted on the end of the first cylinder via a second connecting arm; a rotating sleeve is fixedly mounted on the end of the second cylinder; a central shaft is rotatably mounted through the rotating sleeve, and a mounting frame is fixedly mounted on the outer end of the central shaft, with a pneumatic clamp fixedly mounted inside the mounting frame; a guide cam is fixedly sleeved on the inner end of the central shaft; an L-shaped guide frame is fixedly mounted on the second connecting arm via a third connecting arm and is parallel to the second cylinder; the guide cam is slidably fitted in an L-shaped guide groove in the L-shaped guide frame.

[0012] Furthermore, the transfer mechanism includes a stepper motor vertically mounted on the base, with a swing arm fixedly mounted at the end of the stepper motor; two sets of gear claws are arranged opposite each other on the swing arm, and a placement cavity is formed between the ends of the two sets of gear claws; an extension is provided at the tail of the outer gear claw; and a return spring is also provided on the brackets of the two sets of gear claws.

[0013] A vertical column is set on the base, parallel to the stepper motor and located outside the stepper motor. A stop is fixed to the upper end of the column by a strip plate. After the swing arm rotates, the extension abuts against the stop, and the two sets of gear claws open to release the core column.

[0014] Furthermore, the conveying platform includes wall panels, and a conveying table is fixedly arranged between the wall panels; a cutting table is detachably arranged at the front end of the conveying table; a guide plate is also provided on the wall panel, and a contraction section is integrally provided at the inlet end of the guide plate.

[0015] Furthermore, a collection box groove is provided on the base, which is located directly below the cutting and conveying cavity and is used to collect waste materials.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) This device integrates conveying, length setting, cutting, clamping, flipping and transfer functions on the same base platform, realizing the fully automated operation from belt feeding to the separation and directional transfer of individual resistance wires, reducing manual intervention in intermediate links, greatly improving production cycle and overall efficiency, and is suitable for large-scale continuous production needs.

[0018] (2) By setting up a conveying and cutting mechanism, especially by using a cutting assembly that is driven by the main drive and linked by gear transmission, with the sliding rod, connecting rod and cutting blade linked together, the cutting sequence and stroke can be precisely controlled to ensure the fixed length and stable shearing of the resistance wire on the belt. The cutting action is precisely triggered by mechanical transmission, avoiding errors caused by manual or pneumatic control, effectively preventing incomplete cutting or damage to the resistance section, and improving the consistency and reliability of cutting.

[0019] (3) By setting the coordinated action of the clamping and flipping mechanism and the transfer mechanism, the cut resistance wire can be stably clamped, and the precise flipping can be achieved through the cooperation of the guide cam and the L-shaped guide frame, so that it reaches the preset spatial posture. Then the transfer mechanism accurately sends it into the horn tube or other assembly station, which solves the problem that the input angle of the resistance wire cannot be automatically controlled in the prior art, and significantly improves the assembly accuracy and product yield.

[0020] (4) The conveying bracket adopts a structure combining counterweight and conveying teeth, which ensures good contact with the core column belt under the action of gravity and realizes stable conveying; the force-increasing spring in the cutting component cooperates with the limiting structure to enhance the stability and response speed of the cutting process; the transfer mechanism drives the swing arm through the stepper motor and uses the mechanical limiting of the stop and the extension to realize the automatic opening of the gear claw, which is reliable, accurate in positioning, and the whole machine runs smoothly with a low failure rate.

[0039] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] Example

[0041] like Figures 2-14 As shown, a cutting and transferring device for resistance wires used in the production of light bulb wicks is integrally integrated and installed on a metal base 1. The base is welded from high-strength steel plates, providing good rigidity and stability. A supporting enclosure 2 is provided above the base to enhance structural strength and serve as a reference platform for the installation of other functional modules.

[0042] In this solution, the conveying and cutting mechanism 3 is the core component for realizing automatic feeding and precise cutting of the resistance conductor wire.

[0043] Specifically, the conveying platform 31 consists of two side panels 3102 and a central conveying platform 3101, all fixed to the supporting enclosure 2. A cutting table 3105 is detachably mounted at the front end of the conveying platform 3101. This cutting table is made of wear-resistant alloy steel and has guide grooves and support surfaces that match the cutting blades, facilitating the replacement of different blade sizes to accommodate various resistance wire dimensions. The side panels 3102 also have guide plates 3103, with an integrally formed constriction section 3106 at the inlet end, forming a funnel-shaped inlet that effectively guides the continuous belt smoothly into the conveying channel, preventing deviation or jamming.

[0044] Rectangular notches are provided at both corners of the inner end of the conveying platform 31, forming a cutting and conveying cavity 3104, which provides vertical movement space for subsequent cutting operations. This design avoids interference with the cutting components caused by traditional fully enclosed platforms and improves structural rationality.

[0045] In terms of power, two supports 30 arranged opposite to each other on the base are used to support the transmission system: one support has a transmission box 32 fixedly installed at the top, which is equipped with a first gear 3201, a second gear 3202 and a third gear 3203 that mesh linearly; the other support is equipped with a connecting plate 301 to support the other end of the transmission shaft and ensure smooth transmission.

[0046] During operation, the first drive shaft 3204 passes through the first gear 3201, with one end connected to the external main drive 6 and the other end fixedly connected to the conveying bracket 33. When the main drive 6 starts, the power drives the conveying bracket 33 to rotate periodically. In this design, the main drive 6 includes a motor and a gearbox, and its speed change function is adjusted by the control console 7.

[0047] The conveying bracket 33 includes two parallel strips 3301, one of which is rigidly connected to the first drive shaft 3204 to ensure synchronous rotation. The two strips 3301 are connected by a second connecting rod 3302, on which multiple conveying teeth 3303 are sleeved. In this design, each second connecting rod 3302 is equipped with two teeth, and each conveying tooth 3303 has an integrally formed counterweight 3304 at its bottom. Gravity keeps the teeth of the conveying tooth 3303 always facing upward. The guide wire of the resistance wire overlaps in the teeth of the conveying tooth 3303, providing stable friction during intermittent feeding to prevent slippage or jumping, thereby achieving high-precision fixed-length conveying.

[0048] Meanwhile, the second drive shaft 34 passes through the connecting plate 301 and the transmission box 32, with one end connected to the third gear 3203. Two sets of swing cams 35 are symmetrically mounted on the shaft. The cam profiles are precision machined to ensure stable push and return movements during each rotation.

[0049] In this design, the cutting assembly 36 is located on the inner end of the conveying platform, specifically including: a rotating seat 3606 mounted opposite to each other on the conveying platform 31 to support the third drive shaft 3607; the third drive shaft 3607 spans the two rotating seats 3606, on which two sets of cutting blades 3608 are mounted. The blades are made of high-speed steel or cemented carbide, and the cutting edges are ground to ensure they remain sharp even after long-term use; preferably, the cutting blades 3608 include a mounting bracket and a blade body located on the bracket, which can be replaced as needed. A sliding rod 3602 is slidably arranged inside the hollow sleeve 3601 fixed on the base. The sliding rod 3602 is provided with a limiting ring 36021, and a force-increasing spring 3603 is assembled between it and the end of the hollow sleeve. This spring provides a restoring force and enhances the impact force at the moment of cutting; the two sliding rods 3602 are rigidly connected by a first connecting rod 3604, which is provided with two limiting ring sets 3605, forming an overlapping groove that cooperates with the swing cam 35;

[0050] One end of the first connecting arm 3609 is hinged to the upper end of the slide bar 3602, and the other end is sleeved on the end of the third drive shaft 3607.

[0051] The working process of this mechanism is as follows: When the main drive 6 drives the second transmission shaft 34 to rotate, the swing cam 35 periodically presses down the first connecting rod 3604 to move downward, compressing the force-multiplying spring 3603; the slide rod 3602 descends and converts the linear motion into the rotational motion of the third transmission shaft 3607 through the first connecting arm 3609, driving the cutting blade 3608 to move upward, preparing for cutting; after the cam rotates past the highest point, the force-multiplying spring 3603 rebounds, driving the slide rod 3602 to reset, controlling the blade to cut. The entire cutting process is controlled by mechanical linkage, with rapid response and reliable action, avoiding the delay and leakage problems common in pneumatic or hydraulic systems, and significantly improving the consistency and lifespan of the cutting process.

[0052] The clamping and flipping mechanism 4 is responsible for clamping the cut resistance wire and adjusting it to the required assembly angle.

[0053] Specifically, the clamping and flipping mechanism 4 includes a support frame 40 fixed on the base, on which a first cylinder 41, a double-acting cylinder, is mounted to achieve vertical telescopic movement. The first cylinder 41 is connected to a second cylinder 43 via a second connecting arm 42. The latter is arranged laterally and is used to drive the clamping component to move horizontally left and right.

[0054] A rotating sleeve 46 is fixed to the end of the second cylinder 43, through which the central shaft 411 passes and can rotate freely. A mounting frame 410 is fixedly connected to the outer end of the central shaft 411, and a pneumatic clamp 48, such as a two-finger parallel gripper, is installed inside. The gripper surface is covered with a rubber or polyurethane layer to prevent damage to the surface of the resistance wire. In this solution, the pneumatic clamp 48 is existing technology and will not be described in detail here; it is sufficient to achieve the clamping of the resistance wire.

[0055] A guide cam 412 is fixedly sleeved on the inner end of the central shaft 411. The guide cam 412 is elliptical or quasi-elliptical in shape and slides in the guide groove of the L-shaped guide frame 45. The L-shaped guide frame 45 is fixed on the second connecting arm 42 by the third connecting arm 44 and remains parallel to the second cylinder 43.

[0056] The working process of this mechanism is as follows: When the resistance wire is cut, the first cylinder 41 pushes the entire clamping assembly downward to the predetermined position; the pneumatic clamp 48 clamps the resistance wire, and then the first cylinder 41 controls the clamping assembly to rise, and the second cylinder 43 works. At this time, the guide cam slides along the L-shaped guide groove: the clamping posture remains unchanged when moving in the horizontal section; after entering the vertical section, due to the change in the direction of the guide groove, the guide cam is forced to drive the central shaft to rotate 90°, realizing the spatial flipping of the resistance wire, and changing the resistance wire from a horizontal state to a vertical state.

[0057] The transfer mechanism 5 is used to transfer the flipped resistance wire to the next process.

[0058] Specifically, the transfer mechanism 5 includes a stepper motor 51 vertically mounted on a base, with its output shaft fixedly connected to a swing arm 52. Two sets of gear claws 53 are arranged opposite each other on the swing arm 52, their structure resembling a gear-shaped clamping mechanism, with an inner end forming a placement cavity 50 for accommodating the resistance wire. The outer gear claws have rearwardly extending extensions 54, and a return spring 58 is provided between the two sets of claws, normally closing the claws and clamping the resistance wire.

[0059] The base 1 is also provided with a column 55 parallel to the stepper motor, and a stop 57 is fixed on its top by a strip plate 56, the position of which has been precisely calibrated.

[0060] The working process of this mechanism is as follows: After the gripping and flipping mechanism completes the flipping, the resistance wire held by the pneumatic clamp 48 is located directly above the placement cavity 50. The pneumatic clamp releases, and the resistance wire falls into the placement cavity 50 of the transfer mechanism 5. The stepper motor 51 receives a signal from the control console 7 and rotates precisely at a certain angle, driving the swing arm 52 to move the resistance wire to the target station, such as the inlet end of the conveying unit 9 in this solution. When the swing arm 52 reaches its limit position, the extension 54 makes physical contact with the stop block 57. The continued rotation forces the gear pawl to overcome the return spring and open, automatically releasing the resistance wire and completing the precise placement.

[0061] In this solution, to achieve coordinated control of the aforementioned mechanisms, the device includes a control console 7, integrating a PLC controller, a human-machine interface (HMI), and an electrical junction box. This console is electrically connected to the main drive, stepper motor, cylinders, and sensors, enabling automated and coordinated control of the entire machine. Operators can set parameters such as cutting length, flip angle, and running speed via a touchscreen. The system automatically executes the sequence of actions for each mechanism according to a preset program.

[0062] In addition, a collection box slot 11 is provided on the base 1, located directly below the cutting and conveying cavity. A drawer-type collection box can be inserted to collect metal scrap (such as strip fragments) generated during the cutting process. This design effectively prevents scrap accumulation from affecting equipment operation and also facilitates regular cleaning, improving the cleanliness and safety of the equipment.

[0063] All moving parts are equipped with position sensors (such as proximity switches or photoelectric encoders) to provide feedback on the current position information, ensuring that all actions are synchronized and coordinated, and avoiding misoperation.

Many modifications and variations will be apparent to those skilled in the art.
