[0041] The present utility model will now be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model. In the description of the present utility model, it should be understood that unless otherwise specified, the meaning of "a plurality of" is two or more. In addition, "up" refers to the direction in which the cylinder assembly is close to the pressing arm in the drawings, and "down" refers to the direction in which the cylinder assembly is away from the pressing arm in the drawings.

[0042] Referring to Figures 1 to 4 , a pressing and rotating tooling in a specific embodiment of the present utility model includes a cylinder assembly 1, a pressing arm 3, and a pressing plate assembly 4. Among them, a rotating shaft 11 and a piston 12 are provided inside the cylinder assembly 1, and the piston 12 can drive the rotating shaft 11 to move along the cylinder assembly 1 under the drive of air pressure. More specifically, the rotating shaft 11 has a linear motion stroke and a rotational motion stroke under the push of the piston 12, and since the pressing arm 3 is fixedly connected to the rotating shaft 11, therefore, while the rotating shaft 11 moves, it can drive the pressing arm 3 to perform linear motion and rotational motion synchronously, avoiding interference between the pressing arm 3 and other working structural parts. It should be noted that the power source of the piston 12 is not limited to using a pneumatic cylinder, and a hydraulic power hydraulic cylinder or an electric cylinder can also be used for substitution.

[0043] Referring to Figure 3 , specifically, the cylinder assembly 1 further includes a cylinder barrel 13, and both the rotating shaft 11 and the piston 12 are arranged inside the cylinder barrel 13. More specifically, a groove 2 is formed on the rotating shaft 11, and the groove 2 includes a spiral groove 21 and a linear groove 22. Among them, the linear groove 22 is communicated with the spiral groove 21, and the linear groove 22 is arranged away from the pressing arm 3, so that the piston 12 can drive the rotating shaft 11 to perform linear motion or rotational motion along the groove 2. In addition, the length of the linear groove 22 can be set according to actual needs, and the length of the linear groove 22 is at least set to be greater than the projection length of the spiral groove 21 in the axial direction of the rotating shaft 11, thereby avoiding the trouble of repeatedly adjusting the height of the pressing arm 3 and the pressing plate assembly 4 according to different products, working environments, etc., reducing the line change time when changing different products or working environments, and improving production efficiency. In this embodiment, the axial direction of the rotating shaft 11 is the length direction of the rotating shaft 11. The projection length of the spiral groove 21 in the axial direction of the rotating shaft 11 is: when a horizontal light source irradiates perpendicularly to the rotating shaft 11, the length of the projection of the spiral groove 21 on the rotating shaft 11.

[0044] Referring to Figure 2 and Figure 4, Additionally, both the spiral groove 21 and the linear groove 22 extend along the axial direction of the rotating shaft 11, and the axis of rotation of the spiral groove 21 coincides with the central axis of the rotating shaft 11. The range of the rotatable angle a of the spiral groove 21 in the horizontal plane is: 0° < a ≤ 360°. In one embodiment, the rotatable angle a is 90°. By setting the spiral angle of the spiral groove 21, the pressing arm 3 connected to the rotating shaft 11 can be rotated to any angle as needed to avoid interference with the material taking structure, enabling the material taking structure to quickly perform loading and unloading without having to slowly travel redundant trajectories, thereby greatly reducing the loading and unloading time of the material taking structure.

[0045] More specifically, a bearing follower assembly 23 is provided between the rotating shaft 11, the spiral groove 21, and the linear groove 22. The bearing follower assembly 23 includes a limit post (not shown) that can slide in the groove 2. In this way, while the rotating shaft 11 moves upward relative to the cylinder barrel 13, the advancement of the limit post in the spiral groove 21 forces the rotating shaft 11 to rotate accordingly. And through the bearing follower assembly 23, the rotating shaft 11 can be kept moving stably in the linear groove 22 and the spiral groove 21.

[0046] See Figure 3 , The other end of the pressing arm 3 is provided with a pressing plate assembly 4. Of course, it is not limited to only being able to set the pressing plate assembly 4 here. In principle, other structures that can achieve the grasping function can be set here. In this embodiment, the pressing plate assembly 4 is used for illustration. The pressing plate assembly 4 includes a pressing plate shaft 41, a pressing plate bearing seat 42, and a pressing plate 43. The pressing plate shaft 41 is connected to the pressing arm 3 and can drive the pressing plate shaft 41 to move synchronously when the pressing arm 3 moves. The pressing plate bearing seat 42 is connected to the pressing plate shaft 41, and the pressing plate bearing seat 42 can rotate relative to the pressing plate shaft 41. The pressing plate 43 is arranged in the pressing plate bearing seat 42 for pressing the product and can rotate synchronously with the pressing plate bearing seat 42.

[0047] Specifically, the rotation between the pressing plate bearing seat 42 and the pressing plate shaft 41 is realized through a bearing assembly 44. The bearing assembly 44 includes a face bearing 441 and a deep groove ball bearing 442. Among them, the face bearing 441 is sleeved on the pressing plate shaft 41 and abuts against the pressing plate shaft 41. The deep groove ball bearing 442 is also sleeved on the pressing plate shaft 41, and the deep groove ball bearing 442 is simultaneously connected to the pressing plate bearing seat 42 and the pressing plate 43. When the pressing plate 43 presses the product, the pressing plate bearing seat 42 can rotate synchronously with the pressing plate 43.

[0048] Another specific embodiment of the utility model is a kind of pressing and rotating tooling, which, in addition to ensuring the stable movement of the rotating shaft 11 on the groove 2 through the bearing follower assembly 23, can also realize the linear motion or rotational motion of the rotating shaft 11 through the mutual cooperation of the gear (not shown) and the rack (not shown), specifically, the rack is connected to the piston 12, and the rack can be pushed to move by the piston 12, and the gear is connected to the rotating shaft 11. When the piston 12 pushes the rack to move, the gear and the rack are meshed, and then the gear is driven by the rack to move along the path defined by the rack. Therefore, in order to realize the linear movement of the rotating shaft first and then the rotational movement, a section of the rack is set as a straight line section, and a section connected to the straight line section is set as a curved section, so as to meet the movement path requirements of the rotating shaft. In this embodiment, the structure of the pressure plate assembly 4 is consistent with the above embodiment, and will not be repeated here.

[0049] The product is soaked in paint, and the robot grabs the soaked product and places it on the pallet. When the robot moves out, the holding arm 3 drives the pressure plate 43 to move above the product and avoids the robot, and the robot and the holding arm 3 do not interfere with each other. After the pressure plate 43 is pressed on the product, the pallet rotates horizontally at high speed, thereby driving the product placed on the pallet to rotate and shake off the excess paint on the product. When the product rotates, the pressure plate 43 will rotate with the product and hold the product at the same time to prevent the product from being thrown out of the pallet due to centrifugal force.

[0050] Therefore, through the mutual cooperation between the rotating shaft 11 and the piston 12, the piston 12 first performs an upward movement, and the piston 12 drives the rotating shaft 11 to move upward under the drive of the air pressure. The rotating shaft 11 rises linearly along the linear groove 22 in the groove 2 under the holding of the bearing follower assembly 23. When it reaches the spiral groove 21, as the piston 12 continues to push, the rotating shaft 11 slowly spirals up along the spiral groove 21. At the same time, the holding arm 3 connected to the rotating shaft 11 rotates and rises together with the drive of the rotating shaft 11, so as to achieve the purpose of avoiding related structures (such as a manipulator).

[0051] Then, the piston 12 rotates and presses downward under the drive of air pressure, and drives the rotating shaft 11 to move downward. When the rotating shaft 11 moves downward, it drives the holding arm 3 and the pressure plate assembly 4 to press downward synchronously. When the rotating shaft 11 moves downward, it first rotates and moves downward along the spiral groove 21 with the cooperation of the bearing follower assembly 23. When the rotating shaft 11 moves to the linear groove 22, it moves linearly downward until the pressure plate 43 in the pressure plate assembly 4 can contact the product and complete the pressing of the product.

[0052] After the excess coating on the product is thrown off, the piston 12 moves upward again, simultaneously pushing the rotating shaft 11 upward. When the rotating shaft 11 moves upward to the spiral groove 21, as the rotating shaft 11 moves within the spiral groove 21, the rotating shaft 11 drives the pressing arm 3 to spiral upward. At the same time, the manipulator advances to pick up the product. By continuously repeating the above actions, the operation process of pressing - throwing off materials - picking up the product is completed. The entire process fully realizes automated production, without the need for manual additional operations, greatly improving the operation efficiency.
