[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood by specific circumstances.
[0026] See also Figures 1 to 4 The high-efficiency pickup mechanism of a single motor driving multiple groups of cams in the embodiment of the utility model comprises a mounting plate 1; a driving device 2, comprising a motor 21, a mounting seat 22, a driving shaft 23, a bearing 24 and a cam 25, wherein the mounting seat 22 is fixedly arranged on the mounting plate 1, two groups of the bearings 24 are respectively arranged at both ends of the mounting plate 1, and the two groups of the bearings 24 are aligned with the mounting seat 22, the motor 21 is arranged on the mounting seat 22, the driving shaft 23 is connected to the output shaft of the motor 21, and the driving shaft 23 is passed through the two groups of the bearings 24. The bearing 24, the cam 25 is arranged on the driving shaft 23; at least one group of guide devices 3, including a guide rail 31, a sliding block 32, a follower block 33 and a limiting structure 34, the guide rail 31 is fixedly arranged on the mounting plate 1, the sliding block 32 is slidably arranged on the guide rail 31, the cam 25 is connected to the sliding block 32 through the follower block 33, and the two ends of the limiting structure 34 are respectively arranged on the follower block 33 and the sliding block 32; and a picking device 4 is arranged on the guide device 3.
[0027] In the above embodiment, when the motor 21 is started, its output shaft starts to rotate, thereby driving the drive shaft 23 to rotate. Since the drive shaft 23 is inserted into two sets of bearings 24, the stability and accuracy of its rotation are ensured. As the drive shaft 23 rotates, the cam 25 directly connected thereto also rotates. The design and rotation of the cam 25 improve the precise control of the pickup mechanism, which can convert rotational motion into linear motion. The cam 25 is connected to the sliding block 32 through the follower block 33, and the follower block 33 can sense the position of the cam 25 and trigger the corresponding action. When the cam 25 rotates, the follower block 33 moves up and down, thereby driving the sliding block 32 to move up and down. This design enables the pickup mechanism to accurately control the movement of the sliding block 32 as needed. The limiting structure 34 is used to limit the moving range of the sliding block 32 to prevent it from exceeding the guide rail 31. This ensures that the movement of the sliding block 32 is precise and controllable. On the guide device 3, a variety of pickup devices 4, such as manipulators, clamps, etc., can be set for grabbing or processing target objects. The pickup device 4 can be replaced or adjusted as needed to meet different pickup requirements. The entire system works in coordination with the motor 21, bearing 24, cam 25, follower block 33, slide block 32, limit structure 34 and pickup device 4. One motor 21 drives multiple cams 25 to drive multiple guide devices 3 to move up and down, thereby improving the pickup efficiency of the pickup mechanism and achieving an efficient and reliable pickup function. At the same time, this design is compact and efficient, and the number of pickup mechanisms and corresponding cams 25 can be increased or decreased according to actual needs, and the design is flexible.
[0028] See also Figures 1 to 4 In another embodiment, the picking device 4 includes a suction head 41, an air pipe joint and an adjustment structure 42, the suction head 41 is connected to the air pipe joint, the suction head 41 is arranged on the adjustment structure 42, and the adjustment structure 42 is arranged at one end of the sliding block 32.
[0029] In the above embodiment, the suction head 41 is connected to the trachea joint, so that the suction head 41 can be connected to the external air source through the trachea joint, so as to suck the target object. The adjustment structure 42 is used to adjust and fix the position of the suction head 41 to ensure that it can accurately grasp or pick up the target object. In addition, the adjustment structure 42 can also adjust the posture of the suction head 41 as needed, so that it can adapt to objects of different shapes and sizes. Through this design, the picking device 4 can be more flexible and adaptable to different picking requirements, improving the accuracy and efficiency of picking. At the same time, this design also makes the entire mechanism more compact and easy to operate.
[0030] See also Figures 1 to 4In another embodiment, the adjustment structure 42 includes a first adjustment block 421 and a second adjustment block 422. The first adjustment block 421 is arranged on the sliding block 32 and can rotate horizontally around the sliding block 32. The second adjustment block 422 is arranged on the first adjustment block 421 and can swing vertically based on the end face of the first adjustment block 421.
[0031] In the above embodiment, the entire picking device 4 becomes more flexible and accurate through the cooperation of the first adjustment block 421 and the second adjustment block 422. The first adjustment block 421 can rotate around the sliding block 32 to adapt to different picking angles and positions; and the second adjustment block 422 can swing vertically on the end surface of the first adjustment block 421 to adapt to objects of different shapes and sizes. This design enables the entire picking device 4 to better adapt to various picking requirements and improves the accuracy and efficiency of picking.
[0032] See also Figures 1 to 4 In another embodiment, a fixing rod 11 is fixedly provided on the installation.
[0033] In the above embodiment, the function of the fixing rod 11 is to provide additional support and stability to ensure the stability and accuracy of the entire picking mechanism during operation. The fixing rod 11 is firmly connected to the mounting seat 22 by welding or other means to form a stable overall structure.
[0034] See also Figures 1 to 4 In another embodiment, the guide device 3 further includes a first spring 35 , one end of the first spring 35 is connected to the follower block 33 , and the other end of the first spring 35 is connected to the fixing rod 11 .
[0035] In the above embodiment, when the cam 25 drives the sliding block 32 to move up and down through the follower block 33, the first spring 35 is compressed or stretched accordingly. Due to the elasticity of the spring, it absorbs and releases energy, helps to smooth the movement of the sliding block 32 and reduce the impact. The guiding effect of the first spring 35 can ensure the stable movement of the sliding block 32 on the guide rail 31, avoiding excessive vibration or deviation. At the same time, the buffering effect of the spring can reduce the friction and collision between the sliding block 32 and the guide rail 31, reduce noise and extend the service life.
[0036] See also Figures 1 to 4 In another embodiment, the limiting structure 34 includes a limiting block 341 and a limiting rod 342 , the two limiting blocks 341 are fixedly disposed on the sliding block 32 and the follower block 33 , respectively, and the two limiting blocks 341 are connected through the limiting rod 342 .
[0037] In the above embodiment, a complete limiting structure 34 can be formed by connecting two limiting blocks 341 through a limiting rod 342. The limiting rod 342 is used to connect the two limiting blocks 341 and ensure that the relative position between them is fixed. In this way, when the sliding block 32 or the following block 33 moves, the limiting rod 342 can limit their moving range to prevent them from exceeding the guide rail 31 or colliding.
[0038] See also Figures 1 to 4 In another embodiment, the guide device 3 further includes a second spring 36 which is sleeved on the limiting rod 342 .
[0039] In the above embodiment, the second spring 36 is sleeved on the limit rod 342, which can absorb and release energy, and play a role in shock absorption and protection. When the sliding block 32 or the follower block 33 is subjected to external force, the limit rod 342 will be subjected to corresponding pressure or tension. At this time, the second spring 36 can absorb and buffer this part of the force through its own elastic deformation, thereby reducing the impact on the limit block 341.
[0040] See also Figures 1 to 4 In another embodiment, the motor 21 is a servo motor.
[0041] In the above embodiment, the motor 21 uses a servo motor as a power source. A servo motor is a motor 21 that can respond quickly and accurately control torque and speed. Compared with other types of motors 21, a servo motor has higher dynamic performance, control accuracy and stability, and can better adapt to complex working environments and requirements. The main feature of a servo motor is that it is equipped with a position detection device and a servo driver. The position detection device can monitor the rotation angle and speed of the motor in real time, and feed this information back to the servo driver. The servo driver adjusts the input current or voltage of the motor according to the feedback information, thereby accurately controlling the torque and speed of the motor. This closed-loop control method enables the servo motor to have very high control accuracy and stability.
[0042] See also Figures 1 to 4 In another embodiment, the cam 25 disposed on the driving shaft 23 has a different angle.
[0043] In the above embodiment, by setting the cams 25 at different angles, different displacements, speeds and accelerations in the vertical direction can be achieved, and the four groups of Z-direction picking mechanisms can be sequentially driven to reciprocate at high speed in the Z direction. This design improves the adaptability and versatility of the picking mechanism to different objects, enabling it to complete various picking tasks more efficiently.
[0044] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
