[0029] Frame 100; Frame 100 serves as the basic structure of the entire fixture, providing a stable support platform. Its design needs to consider sufficient strength and rigidity to ensure that it will not deform due to external forces during production, thus affecting positioning accuracy.

[0030] The frame 100 is provided with a conveying mechanism 200 in the middle. The conveying mechanism 200 is located in the middle of the frame 100 and is responsible for conveying the LED beads to be inserted to the designated position. The design of the conveying mechanism 200 needs to ensure smooth and continuous transport to reduce production interruptions and improve efficiency. The conveying mechanism 200 is equipped with a clamping plate 300 for inserting LED beads. The clamping plate 300 includes a template 310 and a support plate 320. Several first support columns 321 are provided at the corners of the support plate 320. The template 310 is supported above the support plate 320 via the first support columns 321. Several second support columns 322 are also provided on the support plate 320 within the coverage area of ​​the template 310 and below it. The clamping plate 300 consists of a template 310 and a support plate 320. The template 310 is supported above the support plate 320 via the first support columns 321. This double-layer structure design ensures the stability of the template 310 and facilitates the fixing and adjustment of the support plate 320. The design of the first support columns 321 and the second support columns 322 not only enhances the structural strength of the clamping plate 300, but also... The template 310 provides necessary support to ensure that it will not shift due to weight or external force during production. The template 310 has several arrayed positioning holes 311, each with two symmetrically arranged guide holes 312 at its edge. The guide holes 312 communicate with the positioning holes 311. Both the positioning holes 311 and the guide holes 312 are circular. Each positioning hole 311, when connected to the two guide holes 312, forms an elliptical positioning through-hole. The upper end of the positioning through-hole has a flared structure. The positioning holes 311 and guide holes 312 on the template 310 together form an elliptical positioning through-hole.

By installing parallel guide rails 411 on the bottom of the movable plate 410 and slidably connecting the mounting plate 500 to them, the smooth movement of the mounting plate 500 on the bottom of the movable plate 410 can be ensured, reducing LED bead positioning errors caused by friction or uneven movement. The design of the guide rails 411 helps to accurately position the mounting plate 500 on the bottom of the movable plate 410, which is crucial for ensuring the accurate placement of the LED beads.

[0038] According to some embodiments of this utility model, the bottom of the mounting plate 500 is provided with a plurality of adsorption devices 510. Each adsorption device 510 includes a vacuum guide groove 511 and a plurality of vacuum suction cups 512 disposed at the bottom of the vacuum guide groove 511 for adsorbing LED beads.
