Detailed Implementation
[0021] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings.
[0022] An automatic material handling robot's ZR axis mechanism includes an R-axis angular contact bearing 1, a sealing ring 2, an R-axis rotation sensor 3, a rotating shaft 4, a fixing nut 5, a slider connecting plate 6, a Z-axis lead screw 7, a Z-axis limit sensor 8, a linear guide rail 9, a motor 10, a coupling 11, and a ZR module base plate 12; wherein: the linear guide rail 9 is mounted on the top of the ZR module base plate 12, the Z-axis lead screw 7 is mounted on the top of the linear guide rail 9, and the slider connecting plate 6 is mounted on the top of the Z-axis lead screw 7; the Z-axis limit sensor 8 is installed between the linear guide rail 9 and the Z-axis lead screw 7.
[0023] A motor 10 is mounted on the top of the ZR module base plate 12 via a motor bracket, and the motor 10 is connected to the Z-axis lead screw 7 via a coupling 11. A motor 10 is also mounted on the top of the slider connecting plate 6 via a motor bracket, and the motor 10 is connected to the rotating shaft 4. R-axis angular contact bearings 1 and sealing rings 2 are mounted on both sides of the rotating shaft 4. An R-axis rotation sensor 3 is mounted on the top of one side of the rotating shaft 4.
[0024] The ZR axis mechanism of the automatic material handling robot also includes a guide assembly, which comprises a guide slider 21, a pressure sensor 22, a buffer spring 23, and a nozzle mounting plate 24. The guide slider 21 is mounted on the front of the nozzle mounting plate 24, the buffer spring 23 is mounted on the outside of the guide slider 21, and the pressure sensor 22 is mounted on the rear of the buffer spring 23. This guide assembly ensures the nozzle remains stable during the movement of the mounting plate. Furthermore, the cooperation of the buffer spring and the pressure sensor allows for the detection of the pressure applied to the product being handled, further improving the stability and accuracy of the material handling process.
[0025] The ZR axis mechanism of the automatic material handling robot also includes a flexible mechanism assembly, which comprises a Z-axis lead screw 31, an R-axis air-passing hollow tube 32, a servo motor 33, and an R-axis lead screw 34. Specifically, the servo motor 33 is mounted on one side of the top of the mounting plate, and its output shaft is connected to the Z-axis lead screw 31. The R-axis air-passing hollow tube 32 is mounted on the top of the Z-axis lead screw 31, and the R-axis lead screw 34 is mounted on one side of the tube. This flexible mechanism assembly allows the mechanism to have a certain degree of flexibility when picking up products, thus adapting to products of different shapes and sizes and improving its compatibility and practicality. The servo motor 33 drives the Z-axis lead screw 31 and R-axis lead screw 34 to precisely control the picking up and rotation of products, further improving the accuracy and stability of the material handling.
[0026] The ZR axis mechanism of the automatic material handling robot also includes a vacuum suction mechanism assembly. This assembly comprises a rubber-coated suction nozzle 41 and a nozzle body 42, with the rubber-coated suction nozzle 41 mounted on one end of the nozzle body 42. The vacuum suction mechanism assembly enables the mechanism to firmly grasp products through vacuum suction, preventing products from falling during handling and improving the stability and safety of the material handling process. The design of the rubber-coated suction nozzle 41 increases the friction between the nozzle and the product, further enhancing the gripping strength. Simultaneously, the combination of the nozzle body 42 and the rubber-coated suction nozzle 41 allows for quick nozzle replacement to adapt to products of different shapes and sizes, improving the mechanism's compatibility and flexibility.
[0027] Operating method of ZR axis mechanism of automatic material handling robot:
[0028] In practical applications, when a product needs to be picked up, the motor 10 is first started, driving the Z-axis lead screw 7 to rotate via the coupling 11. This, in turn, causes the slider connecting plate 6 to move up and down on the linear guide rail 9, adjusting the position of the suction nozzle. Once the suction nozzle reaches the designated position, the vacuum suction mechanism is activated, and the product is firmly gripped by the rubber-coated suction nozzle 41. At this time, the R-axis rotation sensor 3 can monitor the rotation angle of the rotation axis 4 in real time, ensuring that the product can rotate at the predetermined angle. Simultaneously, the Z-axis limit sensor 8 can monitor the movement position of the Z-axis lead screw 7 in real time, preventing the suction nozzle from exceeding its working range and ensuring operational safety.
[0029] The flexible mechanism plays a crucial role in the product suction process. The servo motor 33 drives the Z-axis lead screw 31 and R-axis lead screw 34, enabling the suction nozzle to maintain a certain degree of flexibility when picking up products, thus adapting to products of different shapes and sizes. This flexible suction method not only improves the mechanism's compatibility but also reduces product damage during the suction process, increasing product integrity.
[0030] Furthermore, the guide assembly significantly improves the stability and accuracy of material handling. The guide slider 21 slides on the linear guide rail 9, ensuring the stability of the suction nozzle during the movement of the mounting plate. Simultaneously, the cooperation of the buffer spring 23 and the pressure sensor 22 allows for real-time monitoring of the pressure of the product being sucked, ensuring that the product is not damaged by excessive pressure during suction. When the pressure exceeds the preset value, the pressure sensor 22 will promptly issue an alarm, reminding the operator to make adjustments, thereby ensuring the quality and safety of material handling.
[0031] In summary, the ZR-axis mechanism of the automatic material handling robot provided by this utility model not only has the advantages of simple structure, small size, and easy operation, but also features strong compatibility and practicality. By employing elastic suction and vacuum suction methods, this mechanism can firmly grasp products of different shapes and sizes, preventing products from falling or being damaged during the handling process. Simultaneously, by monitoring parameters such as rotation angle, movement position, and pressure in real time, this mechanism can also ensure the accuracy and safety of material handling. Therefore, this mechanism has broad application prospects in automated production lines.
