Description

Technical Field

[0001] The invention belongs to the technical field of wire stripping for LED lamp production, and in particular relates to a wire stripping machine for LED lamp production. Background Art

[0002] LED lights are solid-state semiconductor devices that convert electrical energy into visible light. Due to their advantages of energy saving, long service life, environmental protection, no flicker, and strong color rendering performance, they are widely used in lighting, traffic signal display, display billboards, interior decoration and other fields. Common LED lights mainly consist of several steps: light source slicing, chip installation, welding assembly, shell assembly, packaging debugging and packaging.

[0003] The wire stripping machine for LED lamp production is mainly used for cutting and insulating the connecting wires of LEDs. It is mainly used to provide the connecting wires required for the production of LED circuit boards. The general wire stripping machine for LED lamp production is mainly composed of: an inlet wheel group, a wire stripping knife group, an outlet wheel group, a control system and other accessories. During operation, the inlet wheel group is used to rub the connecting wires to be processed for feeding. The control system controls the operation of the inlet wheel group to control the conveying distance of the connecting wires, and controls the operation of the wire stripping knife group to clamp, strip and cut the connecting wires. In addition, the control system can control the operation of the outlet wheel group to rub the connecting wires, thereby completing the stripping and cutting process of the connecting wires.

[0004] At present, most of the wire stripping machines used in the production of LED lamps mainly use a wire stripping blade in combination with shearing or rotary shearing to split the insulating sheath that needs to be stripped on the outside of the connecting wire. Although this method can split the insulating sheath that needs to be stripped on the outside of the connecting wire, it requires high cutting accuracy of the wire stripping blade in actual application. When the wire stripping blade cuts shallowly, the insulating sheath cannot be cut in place and the wire cannot be stripped; when the wire stripping blade cuts deeply, the metal core wire inside the connecting wire is damaged, thereby affecting the conductive performance of the connecting wire. This makes the actual application effect of the wire stripping machine for LED lamp production in the prior art poor, and the connecting wire cannot be quickly stripped without damaging the connecting wire.

[0005] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0070] like Figures 9 to 11 As shown, a supporting mesh plate 506 is fixedly connected in the compressed air guide cavity. The supporting mesh plate 506 plays a role of supporting and limiting the storage tube 507.

[0071] like Figures 9 to 11 As shown, a storage cylinder 507 is fixedly installed above the supporting mesh plate 506. The storage cylinder 507 plays a role of storing and limiting the waste collection filter bag 508.

[0072] like Figures 9 to 11 As shown, a waste collection filter bag 508 is installed in the storage cylinder 507, and the waste collection filter bag 508 is arranged below the fixed assembly plate 301 and the movable assembly plate 401. The storage cylinder 507 is used to collect waste generated during the wire stripping process.

[0073] like Figures 9 to 11 As shown, a storage grid frame 509 is fixedly installed between the positive pressure air guide pipe 504 and the air compressor pump 503. The storage grid frame 509 plays a role of storing and limiting the adsorption purification layer 510.

[0074] like Figures 9 to 11 As shown, the storage grid 509 is filled with an adsorption purification layer 510. The adsorption purification layer 510 is convenient for adsorbing and purifying harmful gases contained in the airflow in the storage cylinder 507. Multiple groups of exhaust filters 511 are fixedly connected to the outside of the storage cylinder 507. The filtered and purified gas in the storage cylinder 507 is discharged through the exhaust filter 511.

[0075] like Figures 9 to 11As shown, the upper wire stripping knife 402 and the lower wire stripping knife 403 are fixedly connected to a negative pressure guide scraper 502 on one side away from the positive pressure cleaning scraper 501. A pair of negative pressure guide scrapers 502 are arranged on the side of the upper wire stripping knife 402 or the lower wire stripping knife 403 away from the positive pressure cleaning scraper 501. The debris or harmful exhaust gas generated during the cutting process of the upper wire stripping knife 402 and the lower wire stripping knife 403 is guided and purified by the mutual cooperation of the pair of negative pressure guide scrapers 502 and the positive pressure cleaning scraper 501, thereby improving the environmental friendliness of stripping the LED lamp connection wires.

[0076] like Figures 9 to 11 As shown, an airflow type waste recovery assembly is fixedly mounted below the frame 1, and the airflow type waste recovery assembly includes a pair of negative pressure gas collecting cylinders 512. The gas in the negative pressure type guide scraper 502 is guided by the pair of negative pressure gas collecting cylinders 512, so that the negative pressure type guide scraper 502 is in a negative pressure gas collecting state.

[0077] like Figures 9 to 11 As shown, a pair of negative pressure gas collecting cylinders 512 are both fixedly connected with negative pressure fans 513. The operation of the negative pressure fans 513 is controlled to guide the gas in the negative pressure guide scraper 502.

[0078] like Figures 9 to 11 As shown, a pair of negative pressure air collecting cylinders 512 and the negative pressure guide scraper 502 are connected by a return air pipe 514. The negative pressure air collecting cylinders 512 and the negative pressure guide scraper 502 are connected and conducted through the return air pipe 514, so that the negative pressure guide scraper 502 is in a negative pressure air collecting state.

[0079] like Figures 9 to 11 As shown, a pair of negative pressure gas collecting cylinders 512 are rotatably connected with a limit rotation shaft 515, and the limit rotation shaft 515 is arranged above the negative pressure fan 513. The limit rotation shaft 515 plays a role of fixing and limiting the plurality of filter plates 516.

[0080] like Figures 9 to 11 As shown, multiple groups of uniformly distributed filter plates 516 are fixedly connected to the outer side of the limit rotating shaft 515, and the multiple groups of filter plates 516 are obliquely assembled on the outer side of the limit rotating shaft 515. It is convenient to perform adsorption and filtration processing on the air in the negative pressure air collecting cylinder 512 through the operation of the multiple groups of filter plates 516. At the same time, the multiple groups of filter plates 516 can play a role in preventing impurities from protecting the negative pressure fan 513.

[0081] like Figures 9 to 11As shown, a pair of negative pressure gas collecting cylinders 512 are fixedly connected to the bottom with a back-blowing air pipe 517, and the back-blowing air pipe 517 is set through the storage grid 509. The gas in the negative pressure gas collecting cylinder 512 is discharged through the back-blowing air pipe 517, so that the adsorption purification layer 510 can perform adsorption and filtration treatment on the gas discharged from the back-blowing air pipe 517. At the same time, the waste collection filter bag 508 can be back-blown by the gas discharged from the back-blowing air pipe 517.

[0082] During specific use, the LED connecting wire to be stripped is rolled and assembled on the guide plate 208, the connecting wire to be stripped is guided by the cable guide wheel 209, and the connecting wire to be stripped is placed between a pair of feeding belts 201, and the tensioning drive pulley 203 is rotationally driven by controlling the operation of the driving motor 206. The rotation of the tensioning drive pulley 203 enables the pair of feeding belts 201 to rotate in opposite directions through the mutual engagement of a pair of synchronous gears 205, and the connecting wire to be stripped is frictionally fed by the reverse rotation of the pair of feeding belts 201.

[0083] The wire to be stripped is continuously conveyed between a pair of discharge belts 202 under the friction of a pair of feeding belts 201, and the wire to be stripped is moved between the fixed slitting mechanism 3 and the mobile hot slitting and stripping mechanism 4 by controlling the operation of the driving motor 206. The moving lead screw 408 can be driven to rotate by controlling the operation of the sliding motor 412, so that the gap between the moving assembly plate 401 and the fixed assembly plate 301 can be adjusted by the mutual cooperation of the internal and external threads, so as to facilitate the adjustment and control of the stripping length of the LED connection wire.

[0084] When it is necessary to strip the connecting wire, first, the upper cutter 302 and the lower cutter 303 are moved in opposite directions by controlling the operation of the slitting cylinder 310 and the slitting motor 309, and the connecting wire is cut by the cooperation of the upper cutter 302 and the lower cutter 303. At the same time, the upper stripping knife 402 and the lower stripping knife 403 can be heated by controlling the operation of the heating resistor 405. After the heating is completed, the connecting wire to be stripped is cut to a certain depth by controlling the cooperation of the slitting motor 309 and the slitting cylinder 310, and the incision is heated. At the same time, the moving assembly plate 401 can be moved by controlling the operation of the sliding motor 412, and the upper stripping knife 402 and the lower stripping knife 403 are used to heat cut the connecting wire to be stripped and horizontally slide the connecting wire to be stripped.

[0085] After the stripping is completed, the upper stripping knife 402 and the lower stripping knife 403 are separated from the insulating outer sheath of the connecting wire by controlling the slitting motor 309 and the slitting cylinder 310 to reset, and the stripped connecting wire can be frictionally discharged by controlling the operation of a pair of discharge belts 202.

[0086] During the resetting process of the upper wire stripping knife 402 and the lower wire stripping knife 403, the insulation outer skin of the connecting wire stuck to the cutting edge of the upper wire stripping knife 402 and the lower wire stripping knife 403 is scraped and cleaned by the mutual movement of the upper wire stripping knife 402, the lower wire stripping knife 403 and the pair of positive pressure cleaning scrapers 501. At the same time, a compressed air flow can be generated by controlling the operation of the air compressor pump 503, and the compressed air flow is transported to the pair of positive pressure cleaning scrapers 501 under the action of the positive pressure air guide pipe 504. The pair of positive pressure cleaning scrapers 501 spray out compressed air flow to assist in cleaning the cutting edge of the upper wire stripping knife 402 and the lower wire stripping knife 403, and the pair of positive pressure cleaning scrapers 501 spray out compressed air flow to clean the impurities stuck to the bottom of the positive pressure cleaning scrapers 501. In addition, a pair of positive pressure cleaning scrapers 501 continuously spray compressed air to provide auxiliary protection for the connecting wires during the stripping process, thereby avoiding damage to the connecting wires caused by the higher temperature upper stripping knife 402 and lower stripping knife 403.

[0087] The insulation outer skin of the cut connecting wire can fall into the waste collection filter bag 508 for collection under the action of the upper wire stripping knife 402, the lower wire stripping knife 403 and the compressed air flow. At the same time, the gas in the negative pressure guide scraper 502 can be extracted by controlling the operation of the negative pressure fan 513, so that the negative pressure guide scraper 502 is in a negative pressure state, so that the harmful waste gas and debris impurities generated during the hot cutting of the connecting wire are negatively collected by the negative pressure guide scraper 502. The harmful waste gas and debris impurities flow back into the negative pressure gas collection cylinder 512 under the action of the negative pressure fan 513, and are filtered by multiple groups of filter plates 516 and then transported to the outside of the waste collection filter bag 508. By transporting the airflow to the outside of the waste collection filter bag 508, not only can the gas be filtered and purified by the adsorption purification layer 510, but also the waste collection filter bag 508 can be back-blown and cleaned by transporting the airflow.
