Description

Technical Field

[0001] The present invention relates to the technical field of LED string production equipment, and particularly relates to a ring-rail type double-station LED string production equipment. Background Art

[0002] In outdoor or indoor lighting decorations, colorful light strings are often used decorations. By setting lamp beads of various colors to form light strings of different colors, the surrounding environment and atmosphere can be decorated. Due to its good insulation, the leather wire LED light string can be used outdoors, has a beautiful appearance, a variety of product styles, and very strong anti-stretching and corrosion resistance, and has shown an obvious explosive growth in recent years. At present, the processing of LED light strings adopts an assembly line production mode composed of multiple people, multiple stations, and multiple devices. This production method requires a large number of operators and devices, with high production and management costs, difficult quality control, and huge equipment investment costs.

[0003] Therefore, as the publication number CN212840801U discloses a fully automatic production equipment for straight-line leather wire LED light strings, including a wire feeding device, a wire feeding tensioning device, a peeling device, a conductive device, a soldering tin device, a chip pasting device, a welding detection device, a trimming device, a sealing glue device, a UV lamp curing device, a wire pulling device, a wire winding tensioning device, and a wire winding device. By integrating multiple stations, it can complete the production of finished light strings from raw materials in one go, eliminating a large number of intermediate links, and optimizing the traditional production mode of multiple devices into the current single-machine production mode. Due to the fully automatic design concept, the number of operators is greatly reduced, and one person can operate multiple devices at the same time. The quality control has also changed from traditional manual inspection to automatic inspection by the device, and the product quality is more guaranteed. Therefore, this equipment has the advantages of high production efficiency, more guaranteed quality, stable production, convenient operation, and greatly reduced labor and management costs compared with traditional production.

[0004] As the publication number CN113513713A discloses a fully automatic disc type leather wire light string production device and its production method, including a disc clamping and conveying mechanism and a wire guiding mechanism, a cutting mechanism, a peeling mechanism, a chip welding module, and a glue injection mechanism arranged in sequence around the disc clamping and conveying mechanism. The disc clamping and conveying mechanism is used to clamp the leather wire and intermittently convey the leather wire along a circular path. The wire guiding mechanism is used to guide the leather wire into the disc clamping and conveying mechanism. The cutting mechanism is used to cut the leather wire. The peeling mechanism is used to press down the cut leather wire to expose the copper wire inside the leather wire. The chip welding module is used to weld the chip to the copper wire. The glue injection mechanism is used to inject glue into the copper wire to encapsulate the chip.

[0005] However, in the above-mentioned LED light string production equipment, whether it is a disk machine or a straight-line machine, only a single LED light string can be produced under the same transmission mechanism, resulting in relatively low single-machine production efficiency. Moreover, the above-mentioned equipment occupies a relatively large space. Therefore, the applicant proposes a single-machine device with a double-station processing integrated machine for forming LED light strings. Summary of the Invention

[0045] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below with reference to specific illustrations.

[0046] Combined with the attached Figures 1 to 25 As shown, this embodiment discloses a ring-rail type double-station LED light string production device, including a ring-rail type transmission mechanism 200. The ring-rail type transmission mechanism 200 is used to clamp the lamp wire 100 and achieve intermittent transmission. The ring-rail type transmission mechanism 200 includes two relatively arranged transmission straight rails 220, a transmission curved rail 230 for connecting the two transmission straight rails 220, and a plurality of wire clamping unit groups 240 moving along the transmission straight rails 220 and the transmission curved rail 20. The lamp string processing modules are arranged around the ring-rail type transmission mechanism 200. The lamp string processing modules are divided into two processing module groups. A single processing module group is correspondingly arranged on a single transmission straight rail 220. The processing module group includes a plurality of lamp string processing mechanisms arranged according to the lamp string processing procedures. By optimizing the design of the ring-rail type transmission mechanism 200, using the runway-shaped transmission track, the two-way double-lamp wire transmission can be realized by using the two-side transmission straight rails 220 in cooperation with the wire clamping unit groups 240, and matching with a plurality of lamp string processing mechanisms required for LED lamp string processing, the processing of different procedures can be realized, so that a single machine can complete the processing of double stations, improving the production efficiency of the equipment and reducing the equipment use cost.

[0047] According to the production requirements of LED lamp strings and different specifications, the lamp string processing mechanism can be divided into an inlet mechanism 101, a stripping mechanism 300, a spacing adjustment mechanism 102, a power-on wire support mechanism 400, a chip soldering mechanism 500, a solder paste dispensing mechanism 800, a welding mechanism 600, a wire cutting mechanism 103, a glue dotting and forming mechanism 700, a forming and curing mechanism 104, and a lamp string winding mechanism. Among them, the corresponding positions are arranged according to the requirements of the LED production and processing technology, and some or all of them can be selected. The processing module groups on both sides are usually arranged in a relative manner due to the transmission trajectory. The functions of the corresponding different processing procedures in the above lamp string processing mechanism are the same as those of the corresponding procedures in the existing technology of LED lamp string production.

[0048] Combined with the above, for the power input required in each lamp string processing mechanism, it can be driven by using the commonly used combination of various motors in the existing technology, or by supporting components such as oil cylinders and air cylinders, or by using a multi-stage worm and camshaft connected after the motor input to achieve linkage drive, or the specific power transmission structure can be adjusted correspondingly according to actual needs, which belongs to the common knowledge in this type of equipment.

[0049] In one of the preferred embodiments, the wire clamping group unit 240 is optimized and designed to adopt a multi-bit clamping integrated modular structure to improve the stability of the lamp wire 100 clamping and transmission.

[0050] In a specific structure, the wire clamping group unit 240 is used to clamp the lamp wire 100 and intermittently transport it along the transmission straight rail 220. The lamp wire 100 is directly wound up by the lamp string winding mechanism along the transmission straight rail 220. When the wire clamping group unit 240 passes through the transmission bending rail 230, it no longer clamps the lamp wire until it moves to the transmission straight rail 220 on the other side and clamps the lamp wire 100 transmitted from the wire inlet mechanism 101; when the lamp wire 100 is transported to the area to be processed, a plurality of wire clamping group units 240 located on the transmission straight rail 220 are locked in position through the locking mechanism 210. The locking mechanism 210 includes a positioning locking rod 211 and a positioning seat 212. The positioning locking rod 211 can move up and down along the positioning seat 212. When the positioning locking rod 211 moves upward, the positioning locking rod 211 can be locked with the bottom of the wire clamping moving seat 242. Preferably, the number of the locking mechanisms 210 is four, with two in a group, respectively located at the lower parts of both ends of the transmission straight rail 220, used to lock the wire clamping group units 240 located at both ends of the transmission straight rail 220. After fixing both ends, the stability of the clamping of the entire lamp wire 100 is increased, facilitating the lamp string processing mechanism to process the lamp wire 100 at the corresponding position. Usually, corresponding locking holes 2423 are provided at the bottom of the wire clamping moving seat 242. The number of the locking holes 2423 is multiple and arranged in a straight line, facilitating locking cooperation at different positions, improving the locking effect, and facilitating locking adjustment. The locking holes 2423 are used to be engaged with the upper end of the positioning locking rod 211 to achieve locking and positioning; the loop-type transmission mechanism 200 further includes a wire clamping group transmission mechanism. The wire clamping group transmission mechanism includes a first transmission wheel part 250, a second transmission wheel part 260, and a pulley 270 located between the first transmission wheel part 250 and the second transmission wheel part 260. The wire clamping group unit 240 includes a clamping part module 241 and a wire clamping moving seat 242 for installing the clamping part module 241. The wire clamping moving seat 242 is cooperatively installed with the pulley 270 through a linkage seat 2421. The wire clamping moving seat 242 can move along the transmission straight rail 220 and the transmission bending rail 230 as the pulley 270 rotates. Preferably, a roller part 2422 is arranged at the bottom of the wire clamping moving seat 242 to facilitate the realization of a circular loop, and the loop track adopts a runway-shaped loop structure.

[0051] Among them, the clamping member module 241 includes a clamping base 2411, on which a number of clamping seats 2412 are arranged. The number of clamping seats 2412 are arranged side by side. A single clamping member 2413 is hinged to a single clamping seat 2412. An opening and closing tail seat 2414 is also cooperatively provided between the single clamping member 2413 and the corresponding clamping seat 2412. A return spring member 2415 and a return torsion spring member 2416 are cooperatively provided among the opening and closing tail seat 2414, the clamping member 2413, and the clamping seat 2412. The return spring member 2415 and the return torsion spring member 2416 are used to realize the reset of the opening and closing of the clamping member 2413 and the clamping seat 2412. A pressing mechanism 280 is cooperatively provided on the upper part of the opening and closing tail seat 2414. The pressing mechanism 280 is used to press the clamping member 2413, so that the clamping member 2413 can realize the clamping and opening of the lamp wire 100 relative to the clamping seat 2412. Among them, the pressing mechanism 280 includes a pressing rod 281, a cantilever 282, and a cantilever lifting rod 283 for driving the cantilever 282 to move up and down. The pressing rod 281 is used to press the tail of the clamping member 2413. Among them, some components in the pressing mechanism 280 can be shared on both sides according to the equipment arrangement, so that the clamping member 2413 can realize the clamping and opening of the lamp wire 100 relative to the clamping seat 2412. The cantilever lifting rod 283 is usually cooperatively provided with a driving component. The driving component can be driven by a motor according to the prior art, or can be realized by worm multi-stage transmission. By using the pressing operation of the pressing rod 281 on the tail of the clamping member 2413, the end of the clamping member 2413 is driven to move downward, so that an opening is formed between the front end of the clamping member 2413 and the clamping seat 2412, completing the relaxation of the lamp wire 100. The lamp wire 100 can complete the wire winding with the lamp string winder, realizing the wire routing of the lamp wire 100; when the pressing mechanism 280 is reset, the front end of the clamping member 2413 and the front end of the clamping seat 2412 realize the clamping of the lamp wire 100. As the clamping wire group unit 240 moves along the transmission straight rail 220, the transmission and movement of the position of the lamp wire 100 can be completed, realizing the sequential replacement of different process lamp string processing mechanisms.

Correspondingly, a lower tool rest 350 is arranged below the upper tool rest 320, and a lower peeling tool 340 is arranged in cooperation with the lower tool rest 350. It also includes a peeling seat 330. The upper peeling tool 310, the lower peeling tool 340, and the peeling seat 330 jointly perform the peeling operation on the lamp wire 10, realizing the peeling of the outer layer of the lamp wire, so that the conductors in the lamp wire 100 are exposed, facilitating the bonding of LED chips in subsequent processes, and forming LED lamp beads in this area. Usually, a driving component is arranged in cooperation with the upper tool rest 320 and the lower tool rest 350. The driving component adopts a commonly used structure in the prior art to drive the tool rest up and down.

After the position of the adjustment mounting seat 1022 is moved, it drives the adjustment pressure rod 1021 to press down to stretch the lamp wire 100, completing the adjustment of the spacing between each LED lamp bead in the lamp wire 100.

The driving component is used to drive the support telescopic rod 440. The driving component adopts a commonly used structure in the prior art. The energizing mechanism 410 is used to conduct electricity for each conductor in the lamp wire 100, facilitating the lighting test of the product after the LED chips are welded in the lamp wire 100.

The second solder dispensing rod 812 sequentially dispenses solder at the positions where the first wire and the third wire in the lamp wire 10 are located through the position-changing mechanism 813. By using the double-rod solder dispensing operation, the first solder dispensing rod 811 performs fixed solder dispensing, and the second solder dispensing rod 812 performs movable solder dispensing, which can achieve precise single-wire solder dispensing, improve the solder dispensing efficiency and accuracy. The staggered solder dispensing operation of the second solder dispensing rod 812 is preferably set to perform solder dispensing operations on the first wire and the third wire, which has a relatively large span and avoids the problem of solder paste adhesion due to too small a distance between the wires.
