Description

Technical Field

[0001] The present invention relates to the technical field of material processing, and particularly relates to a material suction and transfer device. Background Art

[0002] For wafer-type materials, the size of the materials is at the micron level, with small dimensions, and usually 1800 - 2500 pcs of materials are distributed on a base paper. Before material processing and installation, it is necessary to use equipment to transfer each material from the base paper to a tray. The prior art is to use equipment with suction nozzles to suck and transfer the materials. Since the base paper has low hardness, when the suction nozzle moves down, it is easy to cause the base paper to sink, making it difficult for the suction nozzle to tightly suck the materials, which seriously affects the transfer of the materials. Summary of the Invention

[0003] Aiming at the above problems, the present invention provides a material suction and transfer device, which can suck and transfer micron-level materials with high precision and high transfer efficiency.

[0004] To achieve the above object, the present invention is solved by the following technical solutions:

An x-axis motion module that moves along the x-axis direction is provided on the operation tabletop. The output end of the x-axis motion module is connected to a first sliding plate. A y-axis motion module that moves along the y-axis direction and a collision adjustment and parallelism module that moves along the x-axis direction are provided on the first sliding plate.

The first slider is the output end of the x-axis motion module, and the first slider is fixedly connected to the first sliding plate.

[0008] Specifically, the y-axis motion module includes a second motor, a second lead screw connected to the output shaft of the second motor, and a second slider slidably connected to the second lead screw. The second slider is the output end of the y-axis motion module, and the second slider is fixedly connected to the second sliding plate.

[0009] Specifically, the collision alignment module includes a third motor, a third lead screw connected to the output shaft of the third motor, a third slider slidably connected to the third lead screw, a first collision rod connected to one end of the third slider, and a second collision rod fixed on the second sliding plate. The second collision rod is located between the first jig and the second jig, and a material accommodating gap is formed between the first collision rod and the second collision rod.

[0010] Specifically, the first jig includes a first lower backing plate and a first upper cover plate fixedly connected to the first lower backing plate by bolts. A first avoidance groove is formed in the middle of the first lower backing plate and the first upper cover plate. The second jig includes a second lower backing plate and a second upper cover plate fixedly connected to the second lower backing plate by bolts.

The first upper pressing needle module includes a first air cylinder and a first upper pressing needle connected to the output end of the first air cylinder. The second upper pressing needle module includes a second air cylinder and a second upper pressing needle connected to the output end of the second air cylinder.

Before the suction nozzle module sucks the material, first use the downward pressure of the first upper pressing needle module and the second upper pressing needle module to press the bottom paper on both sides of the material tightly, and then use the ejector pin module to lift the bottom paper, making it easier for the suction nozzle module to suck the material, providing a good guarantee for the transfer of the material;

[0016] 2. A collision adjustment parallel module is added. After the nozzle module sucks the material, the material is transferred to the material accommodation gap position. Through the collision of the first collision rod and the second collision rod, the placement angle of the material is corrected, thus ensuring the position accuracy during the subsequent material discharging.
