[0002] At present, the steering mechanism is generally a reverse mode steering, which will cause certain damage to the product. The other is a clamp-type steering mechanism, which will produce a large impact force on the product when clamped instantly, and will leave a certain degree of marks on the product surface.

[0003] The existing steering mechanism causes surface wear and damage to the product, and cannot steer the product more accurately without damaging the product. In addition, the reverse mode steering is not compatible with products with different sizes, and the applicability is relatively single. Therefore, it is necessary to design a steering mechanism that avoids damage to the product and has strong compatibility. Utility Model Content

[0024] like Figure 1 and Figure 2As shown, the present embodiment discloses a vacuum adsorption steering mechanism 10, comprising: a mounting seat 11; a rotating device 20, which is arranged on the mounting seat 11; an air path device 30, which is arranged on the mounting seat 11 and cooperates with the rotating device 20; wherein the rotating device 20 comprises a motor 21 and a steering module 22, the steering module 22 is cooperated with and arranged on the main shaft of the motor 21, the air path device 30 comprises independently arranged positive-pressure air paths 32 and negative-pressure air paths 31, the steering module 22 is provided with an air vent 251 for limiting semiconductor components, the positive-pressure air paths 32 and the negative-pressure air paths 31 are both connected to the air vent 251, and the air vent 251 is arranged on the axis of the main shaft of the motor 21.

[0025] By controlling the rotation of the steering module 22 through the motor 21, steering can be achieved more accurately and without damaging the semiconductor component products. The negative pressure of the air path device 30 is used to adsorb the semiconductor components on the steering head. Compared with the existing clamp-type steering, it can effectively avoid damage to the semiconductor component products and has no requirements on the size of the semiconductor components. After the reversal is completed, the positive pressure is switched to provide power to transport the semiconductor components after the reversal away from the steering mechanism 10, thereby achieving the purpose of high-speed reversal for the semiconductor component products; a separate positive pressure air path 32 and a negative pressure air path 31 are set, so that the positive pressure and negative pressure can act on the semiconductor components that need to be reversed separately through the vent 251, ensuring that the entire rotation steering and transportation process away from the reversing mechanism is more efficient; the vent 251 is arranged on the axis of the main shaft of the motor 21, so that the reversing rotation is more efficient.

[0026] Among them, the steering module 22 includes a rotating head seat 23, an air path connector 24 and a reversing seat 25. The motor 21 is arranged on the mounting seat 11 through a flange bearing. The rotating head seat 23 is fixedly sleeved on the main shaft of the motor 21. The air path connector 24 is fixed on the rotating head seat 23. The air path connector 24 is provided with an independent positive pressure channel and a negative pressure channel. The positive pressure air path 32 includes a positive pressure channel, and the negative pressure air path 31 includes a negative pressure channel. The steering mechanism 10 absorbs the semiconductor components onto the reversing seat 25 through negative pressure, and the reversing seat 25 uses the rotation of the motor 21 to reverse the semiconductor components; after the reversal is completed, the positive pressure is switched to provide power to transport the semiconductor components after the reversal away from the reversing mechanism, thereby achieving the purpose of high-speed reversing.

[0027] Among them, the air circuit device 30 includes an air distribution disk 33 and an air disk bracket 34, the air distribution disk 33 is fixedly installed on the air disk bracket 34, and the two ends of the air disk bracket 34 are fixedly arranged on the mounting seat 11, and a positive-pressure air circuit 32 and a negative-pressure air circuit 31 are provided on the air distribution disk 33, and the air circuit connector 24 is cooperated with the air distribution disk 33, and the air disk bracket 34 cooperates with the steering head seat to realize a sealed connection between the air distribution disk 33 and the air circuit connector 24, thereby ensuring the air tightness of the positive-pressure air circuit 32 and the negative-pressure air circuit 31 of the entire steering mechanism 10; optionally, the air distribution disk 33 and the air disk bracket 34 are integrally formed, which can further reduce the components of the steering mechanism 10 and make the assembly of the steering mechanism 10 simpler.

[0028] Among them, the air distribution disk 33 is provided with an arc-shaped groove 331 connected to the negative pressure air circuit 31, and the angle of the arc-shaped groove 331 corresponding to the circumference is greater than or equal to 180 degrees. The arc-shaped groove 331 is connected to the negative pressure air circuit 31. The setting of the arc-shaped groove 331 can effectively solve the continuous input of negative pressure to the negative pressure air circuit 31 during the rotation process, and ensure that the negative pressure adsorbs the semiconductor components to the reversing seat 25 during the entire turning process; the air distribution disk 33 is provided with an air distribution hole 332 connected to the positive pressure air circuit 32, and the air distribution hole 332 is used to input positive pressure alone, providing power to transport the semiconductor components after the turn away from the reversing mechanism, thereby achieving the purpose of high-speed reversing.

[0029] Among them, a guide column 35 is fixedly provided on the mounting seat 11, and linear bearings 351 are fixedly provided at both ends of the air disc bracket 34.

The air disc bracket 34 provides an upward force through the linear bearings 351 and the compression springs 352 to tightly fit the air distribution disc 33 and the air disc adapter block 26 to avoid negative pressure leakage. At the same time, the wear and tear generated during long-term operation can be compensated by the compression springs 352. The function of the air disc adapter block 26 is to separate the direct friction between the air path connector 24 and the air distribution disc 33. The air disc adapter block 26 is made of wear-resistant material, and different materials have different wear speeds.

The sensors 13 are used to sense whether semiconductor components are placed on the reversing seat 25. When the optical fiber of the sensor 13 senses that the semiconductor components are above the reversing seat 25, the steering mechanism 10 adsorbs the semiconductor components onto the reversing seat 25 through negative pressure, and the reversing seat 25 uses the rotation of the motor 21 to reverse the semiconductor components; after the reversal is completed, positive pressure is switched to provide power to transport the semiconductor components after reversing away from the reversing mechanism, thereby achieving the purpose of high-speed reversing.
