[0002] In the light-emitting diode processing technology, the crystal bonding process usually uses crystal bonding equipment for automated operations. Currently in the operation process of the crystal bonding equipment, the material taking component takes the bracket material strip stored on the bracket carrier and puts it in the feeding position, and then the feeding component transfers it to the crystal bonding mechanism. Since there are many types of light-emitting diodes and the corresponding bracket material strips have various specifications, the bracket carrier of the crystal bonding equipment needs to support the storage of multiple bracket material strips. In the prior art, multiple sets of bracket carriers are usually configured for bracket material strips of different specifications, and the mold change production is carried out by replacing the bracket carrier. It is impossible to quickly adjust the bracket carrier to adapt to bracket material strips of different specifications. The production conversion and mold change operation is complicated, time-consuming and labor-intensive, which affects the equipment utilization rate and reduces the equipment output.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] A loading mechanism of a light-emitting diode die bonding equipment comprises a frame, a support platform, a material picking assembly, and a material feeding assembly, wherein the material picking assembly and the material feeding assembly are adjacently arranged on the frame, the support platform is detachably connected to the frame, the support platform comprises a carrier plate, a first bracket, a second bracket, and a bracket sliding unit, the bracket sliding unit is arranged on the carrier plate, the first bracket and the second bracket are parallel to each other and are respectively connected to the bracket sliding unit, and the bracket sliding unit can drive the first bracket and the second bracket to move away from or closer to each other.

[0006] The bracket carrier is designed with adjustable spacing between the first bracket and the second bracket. For bracket strips of different specifications, the spacing between the first bracket and the second bracket is adjusted through the bracket sliding unit, so that it can not only stably support the bracket strips, but also match the material taking component. The suction unit of the material taking component can extend into the bracket carrier to absorb the bracket strips without interference. When switching between different specifications of bracket strips, this design allows the bracket strips to be easily and quickly placed on the bracket carrier without having to replace the bracket carrier, thus achieving rapid switching and improving the utilization rate of the equipment.

[0007] Further, the support sliding unit includes a first sliding seat, a second sliding seat, a slide rail, and a sliding drive unit, the first sliding seat and the second sliding seat are slidingly connected to the slide rail, and the sliding drive unit is drivingly connected to the first sliding seat and the second sliding seat.

[0008] The bracket carrier is used to support the first bracket and the second bracket of the bracket material strip to adjust the spacing through the sliding unit. The first sliding seat and the second sliding seat are placed on the slide rail. The sliding drive unit is designed to be connected with the first sliding seat and the second sliding seat. By controlling the sliding drive unit, the first sliding seat and the second sliding seat can be driven to move away from and close to each other to freely adjust their spacing.

[0009] Furthermore, the sliding drive unit includes a driving member and a driving rod, the driving rod is inserted into and sleeved on the first sliding seat and the second sliding seat, the driving member is connected to the driving rod, and the driving member can drive the driving rod to rotate to drive the first sliding seat and the second sliding seat to move away from or closer to each other.
