The output end of the rotating motor 225 is coaxially fixed to the patch rotating shaft 226, the patch rotating shaft 226 is coaxially fixed to the arc-shaped guide plate 231, and one end of the linear guide plate 232 is connected to the arc-shaped guide plate 231. A plurality of suction nozzles 241 are arranged in a distributed manner, and each suction nozzle 241 is fixed with two guide shafts 242. The guide shaft 242 is fixed to the rear side of the middle section of the suction nozzle 241 and extends from the upper and lower ends of the middle section of the suction nozzle 241. The front ends of adjacent suction nozzles 241 are respectively hinged to the two ends of two hinge rods 243 that are hinged to each other. The hinge points of the hinge rods 243 are provided with torsion springs, so that the two hinge rods 243 tend to open. A T-shaped groove is opened along the outer side of the linear guide plate 232 and the arc-shaped guide plate 231. The suction nozzles 241 are slidably disposed in the groove through the guide shaft 242. The plane adjustment plate 234 is movably disposed parallel to the linear guide plate 232. Outside the plate 232, the conical adjustment plate 233 is vertically movable and disposed outside the arc-shaped guide plate 231. The axis of the conical adjustment plate 233 coincides with the axis of the arc-shaped guide plate 231. The conical adjustment plate 233 and the flat adjustment plate 234 abut against the hinge end of the hinge rod 243, which is hinged to each other. The system also includes a conveying structure 1, a lamp bead feeding machine 21, a lamp bead transfer guide rail 221, a chip placement moving cart 222, a transverse moving seat 223, and a chip placement telescopic cylinder 224.

[0039] In this scheme, by setting up interconnected arc-shaped guide plates 231 and straight guide plates 232, the arrangement and shape of the hinged suction nozzles 241 are guided and restricted. T-shaped guide rails are provided on the arc-shaped guide plates 231 and straight guide plates 232. Two guide shafts 242 extending vertically are fixed on each suction nozzle 241. Both guide shafts 242 slide within the guide rails. When the suction nozzles 241 are arranged on the straight guide plate 232, the suction nozzles 241 are arranged in a straight line. When the suction nozzles 241 are arranged on the arc-shaped guide plate 231, the suction nozzles 241 are arranged in an arc shape with a fixed radius. The arrangement of the suction nozzles 241 can be adjusted at any time by moving on the guide rails. The suction nozzles 241 are connected by hinged rods 243. When the suction nozzles 241 are on the linear guide plate 232, the hinged end of the hinge rod 243 is blocked by the planar adjustment plate 234. Adjusting the distance between the planar adjustment plate 234 and the linear guide plate 232 adjusts the hinge angle of the hinge rod 243, thus adjusting the distance between each suction nozzle 241. Similarly, when the suction nozzles 241 are on the arc-shaped guide plate 231, the hinged end of the hinge rod 243 is blocked by the conical adjustment plate 233, vertically... Adjusting the height of the conical adjustment plate 233 adjusts the hinge angle of the hinge rod 243, thereby adjusting the distance between each nozzle 241. When mounting LEDs on long PCBs, the mounting carriage 222 can be moved and adjusted to achieve multiple LED mounting operations, adapting to PCBs with different numbers of LEDs. When mounting LEDs on annular PCBs, the rotation angle of the mounting shaft 226 is adjusted by rotating the rotary motor 225 to achieve a ring array of LEDs. This device can pick up LEDs from the linearly arranged LED feeder 21 and quickly switch the array pattern and spacing of the nozzles 241 according to the structure of the light source, solving the line changeover problem in the production of multiple types of light sources, significantly reducing equipment adjustment time, and significantly improving mounting accuracy, production flexibility, and overall efficiency.

[0040] In a further embodiment, two traction vehicle bodies 25 are also included.

[0041] In this structure, two traction vehicles 25 are set up to drive the arrangement of suction nozzles 241 to move, thereby realizing the movement of the arrangement of suction nozzles 241. The gear meshing method ensures that the movement of suction nozzles 241 is precise and fast. The gear meshing transmission ensures smooth operation and rapid response, further enhancing the stability and automation level of the equipment's patching, and significantly improving the overall production efficiency.

[0042] A further embodiment includes several telescopic adjustment components 26, which are respectively fixed to the top of the arc-shaped guide plate 231 and the straight guide plate 232, and respectively drive the vertical movement of the conical adjustment plate 233 and the horizontal movement of the planar adjustment plate 234.

The rotating drum 263 is rotatably disposed within the housing 261, and its inner side is threadedly connected to the lead screw 264. The telescopic adjustment motor 262 drives the rotating drum 263 to rotate, causing the lead screw 264 to extend from one end of the housing 261. The embodiment also includes an arc-shaped top plate 271, an arc-shaped push plate 272, and several first sliding rods 273. The arc-shaped top plate 271 is fixed to the arc-shaped guide plate 231. At the top, one end of several first sliding rods 273 is fixedly connected to the arc-shaped guide plate 231. The first sliding rods 273 slide through the arc-shaped top plate 271 and are fixedly connected to the arc-shaped push plate 272. The telescopic adjustment member 26 fixed to the top of the arc-shaped guide plate 231 pushes the arc-shaped push plate 272 to move up and down. The system also includes a flat top plate 281, a flat push plate 282, and several second sliding rods 283. The flat top plate 281 is fixed to the top of the straight guide plate 232. One end of several second sliding rods 283 is fixedly connected to the straight guide plate 232. The second sliding rods 283 slide through the flat top plate 281 and are fixedly connected to the flat push plate 282. The telescopic adjustment member 26 fixed to the top of the straight guide plate 232 pushes the flat push plate 282 to move laterally.

[0043] In this structure, the movement distance of the flat adjustment plate 234 and the conical adjustment plate 233 is controllable and self-locking is formed by the adjustment of the lead screw of the rotary drum 263, ensuring high-precision adjustment of the nozzle 241 spacing.

[0044] In a further embodiment, one end of the hinge rod 243 is hemispherical, so that the hinge point of the two hinge rods 243 is spherical.

[0045] By setting spherical hinge points, the contact sliding between the planar adjustment plate 234 and the conical adjustment plate 233 and the hinge points is made smoother, and the adjustment is more precise.
