Description

Technical Field

[0002] As a new type of light-emitting unit with small size and self-luminous property, micro light-emitting diode (MicroLED) has greater advantages in terms of brightness, resolution, contrast, energy consumption, service life, response speed and thermal stability. A large number of MicroLED light-emitting units are required in the manufacturing process of MicroLED display panels. However, due to the small size of MicroLED, the traditional transfer technology of light-emitting diodes (LED for short) is not applicable, and the MicroLED on the growth substrate needs to be transferred to the backplane through mass transfer technology.

[0003] However, when the existing transfer platforms transfer diode chips, manual transfer operations are required, resulting in low transfer efficiency. Moreover, most of the existing transfer platforms cannot adjust their heights, which is not convenient for workers to operate on the light-emitting diodes on the platforms.

[0031] Working principle: First, start the first motor 3. The output end of the first motor 3 drives the driving rotating shaft 4 to rotate. The rotation of the driving rotating shaft 4 drives the first threaded rod 5 to rotate. The rotation of the first threaded rod 5 drives the first threaded block 6 to move. The movement of the first threaded block 6 drives the vertical rod 7 to move. The movement of the vertical rod 7 drives the first electric push rod 8 to move. The movement of the first electric push rod 8 drives the second electric push rod 10 on the mounting plate 9 to move. The movement of the second electric push rod 10 drives the cylinder 11 on the partition plate 35 to move. The movement of the cylinder 11 drives the clamping plate 16 to move to directly above the growth substrate 32. Then, start the second electric push rod 10. The output end of the second electric push rod 10 drives the two groups of clamping plates 16 to descend to both sides of the light-emitting diodes in the growth substrate 32. Subsequently, start the cylinder 11. The output end of the cylinder 11 drives the connecting plate 12 to move backward. The backward movement of the connecting plate 12 drives the two groups of driving link rods 13 to rotate inward. The inward movement of the driving link rods 13 drives the two groups of driven link rods 15 to rotate inward, driving the clamping plate 16 to clamp and fix the light-emitting diodes to be transferred. Then, the output end of the second electric push rod 10 drives the clamping plate 16 to move upward. Subsequently, following the movement of the first threaded block 6, it finally reaches directly above the driving substrate 34. After that, the output end of the second electric push rod 10 drives the light-emitting diodes on the clamping plate 16 to descend above the driving substrate 34. Start the cylinder 11 again. The output end of the cylinder 11 drives the connecting plate 12 to move forward. The forward movement of the connecting plate 12 drives the driving link rods 13 to rotate outward. The outward rotation of the driving link rods 13 drives the driven link rods 15 to rotate outward. The outward rotation of the driven link rods 15 drives the clamping plate 16 to place the light-emitting diodes on the driving substrate 34. Thus, it can automatically and continuously transfer the light-emitting diodes from the growth substrate 32 to the driving substrate 34, eliminating the need for manual operation, improving the transfer efficiency of the light-emitting diodes. At the same time, the second motor 21 can be started. The output end of the second motor 21 drives the active rotating shaft 22 to rotate. The rotation of the active rotating shaft 22 drives the second bidirectional threaded rod 23 to rotate. The rotation of the second bidirectional threaded rod 23 drives the two groups of second threaded blocks 24 to move relatively. The two groups of second threaded blocks 24 drive the first slider 28 to slide on the first chute 27. At the same time, the two groups of second threaded blocks 24 drive the two groups of support link rods 25 to rotate. The rotation of the two groups of support link rods 25 drives the bottom plate 1 to rise and fall. Thus, it can adjust the height of the bottom plate 1, facilitating the operation of the staff on the light-emitting diodes on the bottom plate 1.
