Description

Technical Field

[0001] This invention belongs to the field of emission electrode preparation technology and relates to an emission electrode forming system. Background Technology

[0002] Ultra-high pressure point light sources are gas discharge lamps filled with mercury and inert gas. During operation, the mercury vapor inside the lamp is under ultra-high pressure. Ultra-high pressure point light sources offer high brightness and are widely used in LCD projectors and searchlights. Chinese patent CN203751526U discloses an electrode molybdenum sheet assembly for an ultra-high pressure point light source. This assembly consists of an emitting electrode, a sealing molybdenum sheet, and lead wires. The emitting electrode is located at the front end. One end of the sealing molybdenum sheet has a laser welding point, and the emitting electrode is welded to this point and connected to the sealing molybdenum sheet. The other end of the sealing molybdenum sheet has a resistance welding point. The lead wires are connected to the sealing molybdenum sheet by resistance spot welding and are coaxially arranged with the emitting electrode. This design offers advantages such as uniform welding energy distribution, high load-bearing strength, and precise dimensions.

[0003] The fabrication process of the emitting electrode typically involves: first, winding the filament (tungsten wire) into a spring; then, cutting the wound spring to the required dimensions; finally, acid-washing and drying the cut product; and then spot-welding the spring onto the electrode. However, this method is complex, and for small emitting electrodes, such as those with a filament diameter of 0.06 mm and a core rod diameter of 0.3 mm, it requires workers to have a high level of concentration, thus significantly increasing worker fatigue.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1) The wire feeding mechanism of this utility model outputs wire, the core rod output mechanism outputs core rod, the clamp holds the core rod and at the same time the wire pressing shaft presses one end of the wire onto the core rod, the rotating motor drives the clamp to rotate and then winds the wire onto the core rod, and then the two are welded together by the welding mechanism to obtain the emitting electrode.

Because the inner diameter of the needle tube matches the diameter of the ultrafine tungsten wire, it can better guide the wire's feeding direction while feeding, avoiding the problem of the ultrafine wire deviating from its feeding direction due to fluctuations in the feeding power caused by a larger outlet diameter of the feeding tube. Through this improvement, the finest wire diameter can reach 0.03mm, and repeated experiments have shown that the feeding and retraction lengths are consistent, meeting the product process requirements.

However, the scope of protection of the present invention is not limited to the following embodiments.

[0044] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0045] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0046] Example:

[0047] like Figure 1 The illustrated emitter electrode forming system includes a wire feeding mechanism 1 for conveying tungsten wire, a mandrel output mechanism 2 for outputting a mandrel, a mandrel rotation and clamping mechanism 3, and a welding mechanism for welding the wire to the mandrel. Wherein... Figures 2-5 As shown, the mandrel rotation clamping mechanism 3 includes a clamp 301, a pressing shaft 302 erected on the front side of one clamping end of the clamp 301, and a rotating motor 303 that is connected to the clamp 301 in a transmission manner. The clamp 301 is used to clamp the mandrel, the pressing shaft 302 is used to press one end of the wire onto the mandrel, and the rotating motor 303 is used to drive the mandrel to rotate around the shaft through the clamp 301 to wind the wire onto the mandrel.

[0048] The wire feeding mechanism 1 outputs wire, the mandrel output mechanism 2 outputs mandrel, the clamp 301 clamps the mandrel and at the same time, the wire pressing shaft 302 presses one end of the wire onto the mandrel. The rotating motor 303 drives the clamp 301 to rotate and thus wind the wire onto the mandrel. Then, the two are welded together by the welding mechanism to obtain the emitting electrode. It has the advantages of simple structure, no need for manual operation, and high level of automation.

[0049] In some specific embodiments, such as Figure 6 and Figure 7 As shown, the wire feeding mechanism 1 includes a conveying assembly, a feeding tube 101, a needle shaft 102, and a needle head 103 arranged sequentially along the wire conveying direction. The conveying assembly includes a wire feeding seat 104, a front baffle 105 and a rear baffle 106 arranged one in front of the other on the wire feeding seat 104, a wire feeding channel 107 passing through the front baffle 105 and the rear baffle 106, and a driving wheel 108 and a driven wheel 109 arranged side by side between the front baffle 105 and the rear baffle 106 and rotating relative to each other to clamp the wire being conveyed. The needle shaft 102 is provided with a feeding through hole 110. One end of the feeding tube 101 is connected to the wire feeding channel 107 of the front baffle 105, and the other end is embedded in the rear end of the feeding through hole 110. The needle head 103 includes a sleeve sleeved on the front end of the needle shaft 102, and a needle tube disposed on the sleeve and connected to the feeding through hole 110. The inner diameter of the needle tube is 0.05 to 0.1 mm.

[0050] In operation, the driving wheel 108 and the driven wheel 109 rotate in opposite directions, clamping the ultrafine tungsten wire and passing it sequentially through the wire feeding channels 107 on the front baffle 105 and the rear baffle 106, into the feeding tube 101. After entering the feeding through-hole 110 of the needle shaft 102, it exits through the needle tube of the needle head 103. Because the inner diameter of the needle tube matches the diameter of the ultrafine tungsten wire, it can better guide the wire's feeding direction while feeding, avoiding the problem of the ultrafine wire deviating from its feeding direction due to fluctuations in feeding power caused by a larger outlet diameter of the feeding tube. Through this improvement, the finest wire diameter can reach 0.03mm, and repeated experiments showed consistent feed and retraction lengths, meeting the product process requirements.

[0051] In some specific embodiments, the wire feeding mechanism 1 includes a stepper motor 111. The output shaft of the stepper motor 111 passes through the bottom of the wire feeding seat 104 and is connected to the drive wheel 108. The wire feeding progress is slowly controlled by the stepper motor 111 to ensure the stability of the ultra-fine wire feeding.

[0052] In some specific embodiments, the wire feeding mechanism 1 includes a motor base plate 112 for supporting the stepper motor 111.

[0053] In some specific embodiments, the wire feeding mechanism 1 includes a needle shaft seat 113 for supporting the needle shaft 102. More specifically, a pressure cap is bolted onto the needle shaft seat 113, and the needle shaft 102 is clamped and fixed between the pressure cap and the needle shaft seat 113. The assembly strength between the pressure cap and the needle shaft seat 113 is adjusted by the bolts.

[0054] In some specific embodiments, the motor base plate 112 is bolted to the needle shaft seat 113.

[0055] In some specific embodiments, the inner diameter of the needle is 0.1 mm.

[0056] In some specific embodiments, the outer diameter of the feeding tube 101 is 2.5 to 3.5 mm and the inner diameter is 0.2 to 0.8 mm; more specifically, the outer diameter of the feeding tube 101 is 3 mm and the inner diameter is 0.5 mm.

[0057] In some specific embodiments, the diameter of the wire is 0.03 mm.

[0058] In some specific embodiments, the wire feeding mechanism 1 also includes a wire spool 114 for carrying the wire roll.

[0059] In some specific embodiments, the mandrel discharge mechanism 2 includes a vibratory plate 201, a baffle 202 that is lifted and lowered at the discharge port of the vibratory plate 201 to block or release material, and a lifting cylinder 203 that is pulsatorically connected to the baffle 202.

[0060] In some specific embodiments, the mandrel rotation clamping mechanism 3 includes a rotary motor 303, a clamp 301 that is connected to the rotary motor 303 for clamping the mandrel, and a pressing shaft 302 erected on the front side of one clamping end of the clamp 301; the mandrel and the rotary motor 303 are coaxially arranged; the distance between the lower edge of the pressing shaft 302 and the clamping surface of the clamp 301 is adapted to the thickness of the wire, so that one end of the wire can be pressed onto the mandrel and wound around the mandrel as the rotary motor 303 drives the mandrel to rotate.

[0061] In this embodiment, the pressing shaft 302 is used to press one end of the wire, thereby fixing the end of the wire while clamping the mandrel. Then, when the clamp 301 rotates with the rotating motor 303, the wire is wound on the mandrel to form a wound mandrel, which has the advantages of simple structure and convenient operation.

[0062] In some specific embodiments, the length of the pressing shaft 302 extending beyond the front side of the clamping end of the clamp 301 is 0.4 to 0.6 mm, more specifically 0.5 mm. This extension length is used to provide a sufficient pressing length to prevent the filament from slipping out.

[0063] In some specific embodiments, a mounting hole is provided on the front side of one clamping end of the clamp 301, and one end of the wire pressing shaft 302 is inserted into the mounting hole. The wire pressing shaft 302 is assembled by insertion and connection to facilitate disassembly and replacement.

[0064] In some specific embodiments, the closest distance between the edge of the assembly hole and the clamping surface of the clamping end is 0.04 to 0.06 mm. This closest distance is determined according to the wire diameter to ensure interference clamping effect.

[0065] In some specific embodiments, the diameter of the pressure shaft 302 is 0.4 to 0.6 mm and the length is 1.5 to 2.5 mm; correspondingly, the diameter of the mounting hole is 0.4 to 0.6 mm and the depth is 1 to 2 mm.

[0066] In some specific embodiments, a 0.5mm hole is made at a certain upward offset distance at the jaw of the clamp 301 as an assembly hole. The distance between the lower edge of the assembly hole and the clamping surface of the clamp 301 is 0.06mm, which is compatible with the diameter of the wire. A wire pressing shaft 302 with a diameter of 0.5mm and a length of 2mm is inserted into the hole, with the head protruding 0.5mm. The clamp 301 is then assembled and installed on the rotating motor 303 to realize the clamping and rotation function.

[0067] In some specific embodiments, clamp 301 picks up a 0.3mm diameter mandrel from the outlet of vibratory feeder 201. After picking up the mandrel, clamp 301 moves from the outlet of vibratory feeder 201 to the outlet of wire feeding mechanism 1. Upon reaching the outlet, clamp 301 opens and feeds the wire material under the clamping shaft 302. While clamping the mandrel, clamp 301 also fixes one end of the tungsten wire through the clamping shaft 302. The rotating motor 303 then begins to rotate, completing the winding process. This improvement enables one-time wire winding, reducing the two processes of winding the wire material and then threading the mandrel, resulting in energy saving and high efficiency.

[0068] In some specific embodiments, the clamp 301 employs a pneumatic clamp opening and closing mechanism.

[0069] In some specific embodiments, the rotating motor 303 is a hollow shaft motor, and the mandrel rotation clamping mechanism 3 also includes a clamp opening and closing member 304, a clamp pull rod 305 and a telescopic cylinder 306 that are sequentially connected to the clamp 301, an abutment plate 307 on the clamp pull rod 305, a return spring 308 sleeved on the clamp pull rod 305, and a motor coupling 309 between the clamp opening and closing member 304 and the output shaft of the hollow shaft motor;

[0070] The clamp opening / closing component 304 includes a housing, two rotating shafts positioned one above the other within the housing, and L-shaped connecting rods 3041 rotatably mounted on the corresponding rotating shafts; such as Figure 4As shown, one end of the L-shaped connecting rod 3041 is provided with a connecting part, and the other end is provided with a waist-shaped hole 3042; the upper L-shaped connecting rod 3041 is connected to the upper side of the clamp 301 through the connecting part, and the connection method can be any existing mechanical component connection method such as welding, plugging, or snap-fit; the lower L-shaped connecting rod 3041 is connected to the lower side of the clamp 301 through the connecting part.

[0071] One end of the clamp rod 305 passes through the hollow shaft of the hollow shaft motor and has side sliding shafts on both sides. The side sliding shafts are slidably embedded in the waist-shaped hole 3042 of the upper and lower L-shaped connecting rods 3041; the other end of the clamp rod 305 slides against the output end of the telescopic cylinder 306.

[0072] One end of the return spring 308 abuts against the rotating motor 303, and the other end abuts against the abutment plate 307, so that when the telescopic cylinder 306 pushes the clamp rod 305, the return spring 308 is compressed, the upper and lower L-shaped connecting rods 3041 rotate outward relative to each other, and the clamp 301 opens; when the telescopic cylinder 306 retracts, the return spring 308 elastically pushes the clamp rod 305, the upper and lower L-shaped connecting rods 3041 rotate inward relative to each other, and the clamp 301 tightens its grip.

[0073] In some specific embodiments, the housing is provided with a sliding hole that is slidably connected to the end of the clamping rod 305. In use, the telescopic cylinder pushes the clamping rod 305, and the clamping clamp 301 tightens to hold the mandrel through the clamping opening and closing member 304.

[0074] In some specific embodiments, the device also includes a base plate 310, on which an assembly through hole is provided, and a rotating motor 303 is mounted on the base plate 310 and its output end passes through the assembly through hole.

[0075] In some specific embodiments, the system further includes a base 4 for supporting the wire feeding mechanism 1, the mandrel discharge mechanism 2, the mandrel rotation clamping mechanism 3, and the welding mechanism, and a moving mechanism 5 for driving the mandrel rotation clamping mechanism 3 to move.

A rotary motor 303 and a telescopic cylinder 306 are respectively fixed on the mounting seat 506. The transverse sliding bracket 502, the longitudinal sliding bracket 504, and the mounting seat 506 are driven by a linear displacement motor.

[0076] In some specific embodiments, the system also includes a conversion gripper 6 located on one side of the output end of the wire feeding mechanism 1. The conversion gripper 6 is used to clamp the mandrel on the clamp 301 so that the clamp 301 is temporarily opened to allow the wire to pass between the pressing shaft 302 and the mandrel. Afterward, the clamp 301 closes to clamp the mandrel and the wire and rotates to wind the wire.

[0077] In some specific embodiments, the welding mechanism includes an upper spot welding electrode 7 and a lower spot welding electrode 8 arranged opposite to each other, and an upper spot welding electrode cylinder and a lower spot welding electrode cylinder respectively used to drive the upper spot welding electrode 7 and the lower spot welding electrode 8.

[0079] In some specific embodiments, the system also includes a camera bracket 10, a hinge seat 11 disposed on the camera bracket 10, and a monitoring camera 12 disposed on the hinge seat 11.

[0080] In some specific embodiments, the system is electrically connected to the aforementioned electric components through a PLC control system, a microcontroller, or other control system to achieve automated control.

[0081] Working principle: The mandrel is poured into the vibratory feeder 201, and the wire is fixed on the wire spool 114. One end of the wire passes through the wire feeding mechanism 1 to reach the designated position. The clamping gripper moves to the discharge port of the vibratory feeder, and the blocking cylinder 203 moves down to discharge the wire. The clamp 302 clamps the mandrel and moves it to the switching gripper 6. The switching gripper 6 clamps the mandrel, and the clamp 302 opens. At this time, the wire feeding mechanism 1 feeds the wire forward to the designated position. The clamp 302 clamps the wire and the mandrel simultaneously. The switching gripper 6 releases, and the rotating motor 303 drives the clamp 302 to rotate for spring winding. After winding is completed, the lower spot welding electrode cylinder rises, and the spot welding mechanism presses down to perform spot welding. After spot welding is completed, the clamping gripper moves to the pneumatic shears to cut the wire. All actions are completed and the cycle ends.
