Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of semiconductor display device manufacturing equipment, in particular to a needle punching machine. BACKGROUND

[0002] MiniLED is a new type of LED display technology derived from small-pitch LED. Since it has excellent display effect and long service life, it has been widely concerned since its inception and is hailed as the next generation of display technology. Its downstream applications cover RGB display screens, notebook computer backlights, television backlights, automotive lighting, and general lighting, among other fields, and have excellent industrial application prospects.

[0003] In the production process of MiniLED, first, chips need to be made on the substrate, and then cut and transferred to the carrier. Each pixel point is composed of one R, G, and B color bead. Since the pitch of MiniLED chips is small, a display screen with a resolution of 1080p requires six million chips. During the transfer of the beads, a needle punching machine is usually used for mass transfer technology. Before the mass transfer operation, the crystals need to be sorted and sorted.

[0004] In related technologies, the substrate is generally selected as a crystal film, and the carrier is generally selected as a transparent carrier such as quartz glass. The needle punching machine generally includes a substrate feeding mechanism, a carrier feeding mechanism, a needle punching mechanism, and a vision mechanism. The substrate feeding mechanism feeds the crystal film, the carrier feeding mechanism feeds the transparent carrier, the crystal film is placed above the transparent carrier, the needle punching mechanism is placed above the crystal film, and the center point of the vision mechanism can be transparent through the transparent carrier and the crystal film. The needle, the transparent carrier, and the crystal film are on the same vertical axis to achieve concentric and coaxial positioning between the needle, the crystal, and the vision mechanism.

[0005] For the related technologies in the above, the inventors believe that when the carrier is selected as an opaque carrier such as PCB, the center point of the vision mechanism cannot be transparent through the opaque carrier to position the needle, the crystal, and the carrier concentrically and coaxially. When the crystal is ejected, it is easy to appear skewed, which greatly affects the processing quality of the product. SUMMARY

The first conveying assembly (32) and the second conveying assembly (33) are used to convey the first placement frame (31) in the horizontal direction. The conveying directions of the first conveying assembly (32) and the second conveying assembly (33) are perpendicular to each other.

5. The acupuncture machine according to claim 4, characterized in that: The first placement rack (31) has two opposite side walls with receiving grooves (14), and the two ends of the receiving grooves (14) are connected. When the first placement rack (31) moves to one side of the positioning plate (132), one end of the receiving groove (14) is aligned with the insertion port (7).

6. The acupuncture machine according to claim 4, characterized in that: The substrate loading mechanism (3) further includes a transfer assembly (34) for transferring the crystal film between the first placement frame (31) and the positioning plate (132). The transfer assembly (34) includes a clamping member (341), a connecting member (342), and a driving member (343). The clamping member (341) is used to clamp the side of the crystal film. The connecting member (342) is used to connect the clamping member (341) to the driving member (343). The driving member (343) is mounted on the first placement frame (31) and is used to drive the clamping member (341) to move toward or away from the positioning plate (132).

7. The acupuncture machine according to claim 6, characterized in that: The driving component (343) includes a driving motor (3431), a driving wheel (3432), and a driving belt (3433). The connecting component (342) is configured as a connecting block. The driving motor (3431) is fixedly mounted on the first placement frame (31). The number of driving wheels (3432) is set to two. One driving wheel (3432) is coaxially fixedly sleeved on the output shaft of the driving motor (3431), and the other driving wheel (3432) is rotatably connected to the first placement frame (31). The driving belt (3433) is wrapped around the two driving wheels (3432). The connecting block is fixedly connected to the driving belt (3433), and the clamping component (341) is fixedly mounted on the connecting block.

8. The acupuncture machine according to claim 4, characterized in that: The carrier loading mechanism (4) includes a second placement frame (41), a third conveying component (42), and a fourth conveying component (43). The second placement frame (41) is used to place the carrier. The third conveying component (42) and the fourth conveying component (43) are used to convey the second placement frame (41) in the horizontal direction. The conveying direction of the third conveying component (42) is parallel to the conveying direction of the first conveying component (32), and the conveying direction of the fourth conveying component (43) is parallel to the conveying direction of the second conveying component (33).
