The rotating shaft 4 is provided with an R-axis angular contact bearing 1 and a sealing ring 2 on both sides. The top of one side of the rotating shaft 4 is provided with an R-axis rotation sensor 3.
[0024] The automatic material taking manipulator ZR axis mechanism further comprises a guide assembly, the guide assembly comprising a guide sliding block 21, a pressure sensor 22, a buffer spring 23 and a suction nozzle mounting plate 24, wherein the front part of the suction nozzle mounting plate 24 is provided with the guide sliding block 21, the outside of the guide sliding block 21 is provided with the buffer spring 23, and the rear part of the buffer spring 23 is provided with the pressure sensor 22.

[0025] The automatic material taking manipulator ZR axis mechanism further comprises an elastic mechanism assembly, the elastic mechanism assembly comprising a Z-axis screw rod 31, an R-axis air passing hollow pipe 32, a servo motor 33 and an R-axis screw rod 34; wherein: the top side of the mounting plate is provided with the servo motor 33, the output shaft of the servo motor 33 is connected to the Z-axis screw rod 31, the top of the Z-axis screw rod 31 is provided with the R-axis air passing hollow pipe 32, and one side of the R-axis air passing hollow pipe 32 is provided with the R-axis screw rod 34.

At the same time, the combination of the suction nozzle body 42 and the rubber-coated suction nozzle 41 enables the mechanism to quickly replace the suction nozzle to adapt to products of different shapes and sizes, improving the compatibility and flexibility of the mechanism.
[0027] The mechanism installation and component connection of the automatic material taking manipulator ZR axis mechanism are as follows: According to the design requirements, the ZR module base plate 12 is used as a basic support component, and a linear guide rail 9 is accurately installed on the top of the ZR module base plate 12 to ensure that the linear guide rail 9 is firmly installed and the levelness meets the requirements. Then, a Z-axis lead screw 7 is installed on the top of the linear guide rail 9, and the Z-axis lead screw 7 is kept parallel to the linear guide rail 9 and the transmission is smooth. A sliding block connecting plate 6 is installed on the top of the Z-axis lead screw 7 to ensure that the sliding block connecting plate 6 is tightly connected with the Z-axis lead screw 7 and can move up and down with the rotation of the Z-axis lead screw 7.
[0028] A motor 10 is installed on the top of the ZR module base plate 12 through a motor bracket, and a shaft coupling 11 is used to reliably connect the output shaft of the motor 10 with the Z-axis lead screw 7, so as to ensure that the motor 10 can effectively drive the Z-axis lead screw 7 to rotate. Another motor 10 is installed on the top of the sliding block connecting plate 6 through a motor bracket, and the output shaft of the motor 10 is connected with the rotating shaft 4, so that the rotating shaft 4 can rotate under the drive of the motor 10.
[0029] An R-axis angular contact bearing 1 and a sealing ring 2 are installed on both sides of the rotating shaft 4, so that the R-axis angular contact bearing 1 provides stable radial and axial support for the rotating shaft 4, and the sealing ring 2 seals the space around the rotating shaft 4 to prevent foreign matter from entering. An R-axis rotation sensor 3 is installed on the top of one side of the rotating shaft 4 to ensure that the R-axis rotation sensor 3 can accurately monitor the rotation angle of the rotating shaft 4. A Z-axis limit sensor 8 is installed between the linear guide rail 9 and the Z-axis lead screw 7, so that it can accurately detect the moving position of the Z-axis lead screw 7.
[0030] For the guide assembly, a guide slider 21 is installed at the front of the suction nozzle mounting plate 24, a buffer spring 23 is sleeved outside the guide slider 21, and a pressure sensor 22 is installed at the rear of the buffer spring 23, so that the guide assembly can realize stable guidance, buffering and pressure detection functions during the product suction process.
[0031] For the elastic mechanism assembly, a servo motor 33 is installed on the top of one side of the mounting plate, the output shaft of the servo motor 33 is connected with a Z-axis lead screw 31, an R-axis air passing hollow pipe 32 is installed on the top of the Z-axis lead screw 31, and an R-axis lead screw 34 is installed on one side of the R-axis air passing hollow pipe 32, so that the elastic mechanism assembly can realize elastic suction and accurate control.
[0032] For the vacuum suction mechanism assembly, a rubber-coated suction nozzle 41 is installed at one end of a suction nozzle body 42, so that the vacuum suction mechanism assembly can firmly grasp the product through the vacuum suction force, and the suction nozzle can be quickly replaced as needed.
[0033] Operation method of the automatic material taking manipulator ZR axis mechanism: Position adjustment: In practical applications, when the product needs to be sucked, first start the motor 10 installed on the ZR module base plate 12, the motor 10 drives the Z-axis screw 7 to rotate through the shaft coupling 11, since the Z-axis screw 7 is connected with the slide block connecting plate 6, and the slide block connecting plate 6 can slide on the linear guide rail 9, thus driving the slide block connecting plate 6 to move up and down on the linear guide rail 9, and then adjusting the position of the suction nozzle, so that the suction nozzle can reach the specified position of the product.
[0034] Product suction: After the suction nozzle reaches the specified position, start the vacuum suction mechanism assembly, contact the product surface through the rubber-coated suction nozzle 41, and firmly grasp the product using the vacuum suction force. During the suction process, the friction between the rubber-coated suction nozzle 41 and the product and the vacuum suction force work together to ensure that the product is stably grasped and avoids falling.
[0035] Angle rotation: After the product is grasped, if angle adjustment of the product is needed, start the motor 10 installed on the slide block connecting plate 6, which drives the rotating shaft 4 to rotate, thus driving the grasped product to rotate. At this time, the R-axis rotation sensor 3 monitors the rotation angle of the rotating shaft 4 in real time and feeds back the angle information to the control system. The control system accurately controls the rotation of the motor 10 according to the pre-set angle requirement, ensuring that the product can rotate according to the pre-set angle to meet the requirements of the subsequent production process for the product angle.
[0036] Pressure detection and control: During the process of sucking the product, the guide assembly plays an important role. The guide slide block 21 smoothly slides on the linear guide rail, ensuring the stability of the suction nozzle during the movement of the mounting plate. The buffer spring 23 plays a buffering role when the suction nozzle contacts the product, avoiding rigid collision between the suction nozzle and the product, which may cause damage to the product. At the same time, the pressure sensor 22 detects the pressure of sucking the product in real time and feeds back the pressure signal to the control system. When the pressure exceeds the pre-set value, the pressure sensor 22 will timely send an alarm signal, and the control system will receive the alarm signal and take corresponding measures, such as adjusting the position of the suction nozzle or the size of the suction force, to ensure that the product will not be damaged by excessive pressure during the suction process, thereby improving the stability and accuracy of material taking.
[0037] Elastic adaptation: The elastic mechanism assembly also plays a key role in the entire material taking process. The servo motor 33 drives the Z-axis screw 31 and the R-axis screw 34, so that the suction nozzle can have a certain elasticity when sucking the product. When encountering products of different shapes and sizes, the elastic mechanism assembly can automatically adjust the position and angle of the suction nozzle according to the specific circumstances of the product, thereby adapting to the shape changes of the product, reducing the damage to the product during the suction process, and improving the intact rate of the product. At the same time, this elastic suction method also greatly improves the compatibility of the mechanism, making it able to handle multiple different types of products.
[0038] Safety protection: the Z-axis limit sensor 8 monitors the moving position of the Z-axis screw rod 7 in real time, when the moving of the Z-axis screw rod 7 exceeds the set working range, the Z-axis limit sensor 8 immediately sends a signal, and the control system receives the signal and quickly stops the operation of the motor 10, preventing the suction nozzle from exceeding the working range, avoiding equipment damage or safety accidents caused by excessive movement, and ensuring the safety of operation.
[0039] In summary, the automatic material taking manipulator ZR axis mechanism provided by the present application has the advantages of simple structure, small size, easy operation, strong compatibility and strong practicality. By adopting advanced technical means such as elastic suction and vacuum suction, the mechanism can firmly grasp products of different shapes and sizes, effectively avoiding product dropping and damage during taking and placing. At the same time, by real-time monitoring of key parameters such as rotation angle, moving position and pressure, the mechanism can ensure the accuracy and safety of material taking, and has a wide application prospect in automatic production line, which can significantly improve production efficiency and product quality.
