[0026] In the above embodiment, first, the material state identification mechanism 1 detects the state of the material through the photoelectric sensor 11 on the fixing device 12. The photoelectric sensor 11 can identify the type and position of the material by the color difference according to the color of the material and the color difference of the carrier film on the stage. When the photoelectric sensor 11 detects the color difference of the material, it will transmit the signal to the control system 4, and the control system 4 controls. According to the received signal, the control system 4 controls the Z-direction drive device 2 to act, and the Z-direction drive device 2 drives the picking mechanism 3. The rotating device 31 in the picking mechanism 3 starts to work and drives the shaking device 32 to rotate. The shaking device 32 is connected to the rotating device 31 through the connecting block 33, and shakes with the rotation of the rotating device 31, so that the material is separated from the material pile and sucked into the buffer suction cup 36. In this process, the first throttle valve 35 plays a role in adjusting the shaking amplitude to ensure that the material can be stably sucked into the buffer suction cup 36. Finally, the buffer suction cup 36 absorbs the material, and then adjusts the angle of the material through the rotating device 31 and the shaking device 32. The whole material picking process realizes the correction of material state and the automation of material picking through the photoelectric sensor 11 identifying the material state and the control system 4 controlling the Z-direction drive device 2. In summary, this material picking mechanism recognizes the material color difference through the photoelectric sensor 11, further judges the material state, and uses the Z-direction drive device 2 and the picking mechanism 3 to correct and pick up the material, thereby realizing automated and efficient material processing.

[0027] See also Figures 1 to 4 In another embodiment, the Z-axis driving device 2 includes a first cylinder 21, a floating joint 22, a guide rail 23, a slider 24, a second throttle valve 25 and a buffer 26, the floating joint 22 is arranged at the output end of the first cylinder 21, the slider 24 is slidably arranged on the guide rail 23, the floating joint 22 is connected to the slider 24, the buffer 26 is arranged between the first cylinder 21 and the slider 24, and the second throttle valve 25 is arranged on the first cylinder 21.

[0028] In the above embodiment, the first cylinder 21 is the main driving source of the Z-direction drive device 2, and a floating joint 22 is provided at its output end. When the first cylinder 21 receives an instruction from the control system 4, it pushes the slider 24 to move along the guide rail 23 in the Z direction. The slider 24 slides on the guide rail 23, and the guide rail 23 plays a guiding and supporting role to ensure that the slider 24 can move stably. At the same time, the floating joint 22 is connected to the slider 24, so that the rotating device 31 can rotate with the movement of the slider 24. The buffer 26 is arranged between the first cylinder 21 and the slider 24, which plays a role of shock absorption and buffering, reduces the impact and vibration of the slider 24 when it moves, and improves the stability and reliability of the material picking mechanism. The second throttle valve 25 is arranged on the first cylinder 21, which is used to adjust the air output of the cylinder, thereby controlling the moving speed and stroke of the slider 24. By adjusting the second throttle valve 25, the movement of the slider 24 can be accurately controlled to ensure that the material picking mechanism can accurately identify and correct the material. This Z-axis driving device 2 has a simple and compact structure and can respond quickly and accurately to the instructions of the control system 4 .

[0029] See also Figures 1 to 4 In another embodiment, the rotating device 31 includes a rotating cylinder, and the rotating cylinder is arranged at one end of the slider 24.

[0030] In the above embodiment, the rotary cylinder is arranged at one end of the slider 24. The rotary cylinder can rotate with the movement of the slider 24, thereby realizing the overall rotation movement of the material picking mechanism. The rotation movement of the rotary cylinder is controlled by the command issued by the control system 4. When the control system 4 issues a rotation command, the rotary cylinder will start to rotate, driving the entire material picking mechanism to perform a rotation movement. This helps to expand the material picking range of the material picking mechanism and improve the material picking efficiency. At the same time, the setting of the rotary cylinder also makes the structure of the material picking mechanism more compact, reduces the space occupied, and makes it more suitable for operation in a limited space. In addition, the rotary cylinder also has good rotation stability and reliability, which can ensure the accuracy and reliability of the material picking mechanism.

[0031] See also Figures 1 to 4 In another embodiment, the material shaking device 32 includes two material shaking cylinders, the two material shaking cylinders are respectively arranged at two ends of the rotating cylinder, and the connecting block 33 is located between the two material shaking cylinders.

[0032] In the above embodiment, the material shaking cylinders are respectively arranged at the two ends of the rotating cylinder. This design enables the material shaking cylinders to perform corresponding actions as the rotating cylinder rotates, thereby achieving the shaking and separation of the materials.

[0033] The connecting block 33 is located between the two shaking cylinders, and plays the role of connecting and fixing the two shaking cylinders. Through the connection of the connecting block 33, the two shaking cylinders can work in coordination to ensure the consistency and stability of the shaking and separation actions.

[0034] See also Figures 1 to 4 In another embodiment, the fixing device 12 includes a first connecting plate 121 and a first connecting plate 122, each of the first connecting plates 122 is provided with a sliding groove, one end of the first connecting plate 121 is arranged in the sliding groove of the first connecting plate 122, and the photoelectric sensor 11 is fixedly arranged in the sliding groove.

[0035] In the above embodiment, a sliding groove is provided on the first connecting plate 122 for fixing and guiding the photoelectric sensor 11. One end of the first connecting plate 121 is arranged in the sliding groove of the first connecting plate 122, so that the first connecting plate 121 can move along the sliding groove. The photoelectric sensor 11 is fixedly arranged in the sliding groove, and the photoelectric sensor 11 can move linearly along the sliding groove through the movement of the first connecting plate 121. This design enables the photoelectric sensor 11 to flexibly adjust its position so as to better detect the state of the material. The function of the fixing device 12 is to fix and guide the photoelectric sensor 11 to ensure that the photoelectric sensor 11 can accurately detect the material. At the same time, the fixing device 12 also plays the role of connecting and fixing other components, making the structure of the entire material picking mechanism more compact and stable. The design of this fixing device 12 simplifies the installation and adjustment process and improves the practicality and reliability of the material picking mechanism. By adjusting the moving distance and position of the first connecting plate 121, the detection range of the photoelectric sensor 11 can be accurately controlled to meet the requirements of different materials and processes.

[0036] See also Figures 1 to 4 In another embodiment, the first throttle valve 35 and the second throttle valve 25 are both pneumatic throttle valves.

[0037] In the above embodiment, the pneumatic throttle valve is a valve for adjusting pneumatic flow and pressure, which can control the flow and pressure of the gas, thereby achieving precise control of the material picking mechanism. In the material picking mechanism, the pneumatic throttle valve plays an important role. First, the first throttle valve 35 is used to adjust the gas flow and pressure of the material shaking device 32 to ensure that the material can be stably separated and fall into the buffer suction cup 36. By adjusting the first throttle valve 35, the shaking force and amplitude of the material shaking device 32 can be controlled to achieve effective separation of different materials. Secondly, the second throttle valve 25 is used to adjust the gas flow and pressure of the Z-axis drive device 2, thereby controlling the moving speed and stroke of the slider 24. By adjusting the second throttle valve 25, precise control of the movement of the slider 24 can be achieved, ensuring that the material picking mechanism can accurately identify and correct the material.

[0038] See also Figures 1 to 4 In another embodiment, a limit plate 5 is further included, which is arranged between the slider 24 and the rotating cylinder.

[0039] In the above embodiment, the main function of the limit plate 5 is to limit the moving range of the slider 24, ensuring that the slider 24 does not exceed the set moving range, thereby ensuring the stability and reliability of the material picking mechanism. The limit plate 5 limits its moving range by contacting the slider 24. When the slider 24 moves on the guide rail 23, the limit plate 5 will contact the slider 24, thereby limiting its further movement. This limiting effect can prevent the slider 24 from exceeding the predetermined range, avoiding damage to the material picking mechanism or affecting its normal operation.

[0040] See also Figures 1 to 4 In another embodiment, the rotating cylinder and the shaking cylinder are both provided with heat dissipation holes.

[0041] In the above embodiment, by providing heat dissipation holes on the rotating cylinder and the shaking cylinder, the heat inside the cylinder can be effectively transferred to the external environment. The design of the heat dissipation holes can increase the heat dissipation area of ​​the cylinder and improve the heat dissipation efficiency, thereby reducing the temperature inside the cylinder. This helps to maintain the normal operating temperature of the cylinder and avoid damage to the cylinder or performance degradation caused by overheating.
