[0015] Beneficial Effects

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. When the present invention is used, the main body tube is used to pull the movable plate upward, so that the suction straw absorbs and fixes the electronic components. At the same time, the movable plate moves upward to squeeze the air inside the main body tube. The air control airbag can automatically adjust its expansion degree according to the actual size and shape of the component to form a tight and uniform wrapping layer to pick up the electronic components, thereby enhancing the stability of the device fixation, ensuring the stability and safety of the electronic components during the picking process, and reducing the risk of falling off due to vibration or impact. Electronic components with irregular surfaces, fragile surfaces or special materials can be wrapped and fixed, and the softness of the airbag itself will not cause scratches, indentations or stress concentration to the electronic components.

[0018] 2. When the present invention is used, the saw gear is driven to rotate by connecting the rotating shaft through a motor, and then the gear ring is driven to control the rotation of the rotating rod, so that the clamping plate clamps relatively sharp fixed electronic components, which can easily cope with sharp electronic components of different shapes and sizes, ensuring sufficient clamping force to fix sharp electronic components, and preventing possible damage to the airbag, thereby extending the service life of the device.

[0019] 3. When the present invention is used, the main gear is driven to drive the slave gear to rotate through the second motor connected to the rotating shaft, so that the bottom surface of the picking structure can be extremely accurately perpendicular to the target electronic components, effectively avoiding picking failure or component damage caused by angle deviation, greatly improving the yield rate of the production line, and cooperating with the robot arm to obtain a larger output torque, so as to easily cope with the picking tasks of electronic components of different weights, sizes and shapes, improve the overall work efficiency, and improve the flexibility and production efficiency of the production line.

[0020] 4. When the present invention is used, the transmission belt and the conveying block are driven to rotate by connecting the transmission active roller with the transmission transmission roller through the driving motor, and the electronic components are conveyed to the bottom of the picking structure by the electromagnetic plate. The conveyor belt is composed of multiple plate chains, and three plate chains are spaced between every two conveying blocks, so that there is a distance between the electronic components to avoid the airbag from touching other electronic components when wrapping the electronic components, effectively avoiding damage or positioning errors that may be caused by mechanical contact, reducing maintenance costs and downtime. At the same time, the electromagnetic plate generates magnetic force to firmly adsorb the electronic components on the surface, achieving immediate initial fixation, ensuring that the electronic components will not be accidentally displaced or dropped during subsequent processing, thereby improving the safety and reliability of the production line, and the upper surface of the electromagnetic plate is flat, which will not affect the subsequent picking of electronic components by the picking structure, ensuring the smoothness of the device picking operation.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] A silicone pad 407 is fixedly installed at the bottom end of the straw 402 to reduce wear, and the straw 402 is connected to the inside of the main tube 401;

[0033] The material of the movable plate 406 is set as silicone to enhance the sealing of the inner cavity of the main tube 401. The inner cavity of the main tube 401 is divided into two parts by the movable plate 406. The top of the movable plate 406 is set as an injection cavity 409 for injecting gas into the airbag 403, and the bottom of the movable plate 406 is set as an exhaust cavity 410 for driving the suction tube 402 to extract gas to adsorb electronic components.

At the same time, the movable plate 406 moves upward to generate negative pressure in the inner cavity of the air extraction cavity 410, and then drives the suction tube 402 to adsorb and fix the electronic components. On the contrary, the electric rod 405 drives the movable plate 406 to move downward along the inner cavity of the main tube 401, and the air in the air extraction cavity 410 is withdrawn from the suction tube 402, so as to release the electronic components, and cooperate with the gas pipe 404 to evacuate the air so that the air bag 403 is deflated and the electronic components are loosened;

[0038] The gear ring 412 meshes with the inner cavity of the rotating rod 413, and the rotating rod 413 is turned over by the rotation of the gear ring 412. A motor 415 is fixedly installed on one side of the fixed ring 411, and a rotating shaft 416 is fixedly installed on the output end of the motor 415. A sawtooth gear 417 for driving the gear ring 412 to rotate is fixedly installed on the top of the rotating shaft 416. A sawtooth groove is opened on the outer wall of the gear ring 412, and one side of the sawtooth gear 417 meshes in the sawtooth groove;

[0039] See also Figure 3 The outer wall of the clamping plate 414 is fixedly connected with a connecting rope 418, and the top of the connecting rope 418 is fixedly connected to the bottom end of the control ring 408, so that the control ring 408 can be rotated to drive the airbag 403 to move upward to leak out the clamping plate 414, and the connecting rope 418 can be used to drive the clamping plate 414 to flip and bend, so that the electronic components can be clamped and fixed more conveniently, and can easily cope with sharp electronic components of different shapes and sizes, prevent damage to the airbag 403, and extend the service life of the device.

[0045] A plurality of conveying blocks 605 for transporting electronic components are fixedly installed on the top surface of the conveyor belt 603. The conveyor belt 603 is composed of a plurality of plate chains, and three plate chains are spaced between every two conveying blocks 605, so that there is a distance between the electronic components to prevent the airbag 403 from touching other electronic components when wrapping the electronic components. An electromagnetic plate 606 for preliminarily fixing the electronic components is fixedly installed on the top surface of the conveying block 605.

At the same time, the movable plate 406 moves upward to generate negative pressure in the inner cavity of the vacuum chamber 410, thereby driving the straw 402 to adsorb and fix the electronic components. Conversely, the electric rod 405 drives the movable plate 406 to move downward along the inner cavity of the main tube 401, and the air inside the vacuum chamber 410 is withdrawn from the straw 402, thereby releasing the electronic components, and cooperating with the air supply pipe 404 to evacuate the air bag 403 to deflate and loosen the electronic components.
