Description

Technical Field

[0001] This utility model relates to the field of industrial production equipment, and in particular to a material discharge rotating structure. Background Technology

[0002] In industrial automated production lines, the rotary discharge structure is a key functional unit. It is responsible for removing processed or inspected workpieces from one machine, transferring them precisely to the next workstation or conveyor after necessary orientation changes. Its performance directly affects the cycle time and efficiency of the entire production line.

[0003] Currently, most traditional material handling structures on the market use a purely pneumatic drive system. They typically employ a series of cylinders, such as lifting cylinders and translation cylinders, to sequentially execute linear movements like forward / backward and up / down motions to achieve the material handling path. Rotary movements often require an additional rotary or oscillating cylinder.

[0004] However, this traditional structure has significant limitations. Relying on the sequential action of multiple linear cylinders, its overall structure is lengthy and complex, occupying considerable installation space and exhibiting a slow cycle time, thus limiting further improvements in production line efficiency. Furthermore, the structure of multiple cylinders in series has poor rigidity, making it prone to swaying and positional deviations during high-speed operation, affecting the stability and accuracy of material output. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by using a servo motor-driven vertical module to achieve fast and precise Z-axis motion, significantly improving cycle time. The rotating module and end effector, connected by a connecting sleeve and bracket, form a triangular support structure that greatly enhances system rigidity and effectively suppresses swaying during high-speed rotation. This solves the core problems of slow cycle time, poor rigidity, and inaccurate positioning in traditional structures, resulting in a more compact and efficient overall structure.

[0006] In order to solve the above-mentioned technical problems, the present invention solves the problems of the traditional pure pneumatic discharge structure being long and complex, slow in motion, poor in rigidity, and prone to shaking and positional deviation during high-speed motion due to the multiple cylinders connected in series.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A rotating module is mounted on the moving end of the vertical motion module via a fixed plate and is driven by a rotary cylinder to achieve horizontal rotation.

[0011] An end effector, mounted on the output shaft of the rotary module, is used to clamp the workpiece;

[0012] The end effector is fixed to the middle of the output shaft of the rotary cylinder by a connecting sleeve. A bracket extends from the top of the connecting sleeve, and the other end of the bracket is fixed to the top of the fixing plate to form a stable support.

[0013] Preferably, the vertical motion module includes a servo motor, a transmission component, and a vertical guide rail, wherein the transmission component is a lead screw transmission mechanism or a synchronous belt transmission mechanism.

[0014] Preferably, the rotation angle of the rotating module is 0-180 degrees.

[0015] Preferably, the end effector is a pneumatic gripper, and the inner side of its gripper is provided with an arc-shaped profile that matches the shape of the workpiece.

[0016] Preferably, the end effector includes a plurality of pneumatic grippers arranged in parallel for simultaneously gripping multiple workpieces.

[0017] Preferably, the output shaft of the rotary module has parallel mounting slots at both ends, and the mounting slots have multiple sets of mounting holes for mounting end effectors of different specifications.

[0018] Preferably, it also includes a vertical support column, the vertical motion module is mounted on the vertical support column through bolt holes provided on its back, and the bottom of the vertical support column is provided with a mounting base plate for fixing.

[0019] Preferably, rubber cable trays are installed on both sides of the vertical support column.

[0020] Preferably, the vertical motion module is equipped with buffer devices at both the upper and lower limit positions.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] The discharge rotation structure provided in this application achieves fast and precise Z-axis motion through a vertical module driven by a servo motor, significantly improving cycle time.

The overall structure is more compact and efficient. Attached Figure Description

[0033] Example:

[0034] Please see Figure 1-3 A material discharge rotation structure includes: a vertical motion module 1 for providing linear reciprocating motion along the Z-axis; a rotation module 2, which is mounted on the moving end of the vertical motion module 1 via a fixed plate 21 and driven by a rotary cylinder 22 to achieve horizontal rotational motion; and an end effector 3, which is mounted on the output shaft 23 of the rotation module 2 for clamping the workpiece. The end effector 3 is fixed to the middle of the output shaft 23 of the rotary cylinder 22 via a connecting sleeve 31, and a bracket 32 ​​extends from the top of the connecting sleeve 31. The other end of the bracket 32 ​​is fixed to the top of the fixed plate 21 to form a stable support.

[0035] The discharge rotation structure of this application mainly consists of a vertical motion module 1, a rotation module 2, and an end effector 3. The vertical motion module 1 is mounted on a vertical support column 4 through bolt holes on its back, and a mounting base plate 41 for fixing is provided at the bottom of the column. Rubber cable trays 42 are installed on both sides of the vertical support column 4 to organize and protect the air pipes and electrical cables.

[0036] The vertical motion module 1 includes a servo motor 11, a transmission assembly 12, and a vertical guide rail 13. The transmission assembly 12 can be a lead screw drive mechanism or a synchronous belt drive mechanism, which is not shown in the figure. The servo motor 11 drives the motion platform to perform high-precision linear reciprocating motion along the vertical guide rail 13 through the transmission assembly 12.

[0037] The rotary module 2 is mounted on the moving end of the vertical motion module 1 via a fixed plate 21. The rotary module 2 is driven by a rotary cylinder 22 and can achieve horizontal rotation from 0 to 180 degrees. The output shaft 23 of the rotary cylinder 22 has parallel mounting grooves 231 at both ends, and multiple sets of mounting holes 232 are pre-set on the grooves to accommodate end effectors 3 of different specifications.

[0038] The end effector 3 is fitted and fixed to the middle of the output shaft 23 of the rotary cylinder 22 via a connecting sleeve 31. A bracket 32 ​​extends from the top of the connecting sleeve 31, and the other end of the bracket 32 ​​is directly fixed to the top of the fixed plate 21, forming a stable triangular support structure. This structure effectively enhances the rigidity of the end effector 3 during high-speed rotation and lifting, suppresses vibration, and reduces positional deviation to achieve stable and precise positioning.

[0039] The end effector 3 can be a pneumatic gripper 33, with an arc-shaped profile 331 on the inner side of its gripper that matches the shape of the workpiece to improve gripping stability and centering. Depending on actual production needs, the end effector 3 can also include multiple pneumatic grippers 33 arranged in parallel to grip multiple workpieces simultaneously, thereby improving discharge efficiency.

[0040] To further improve motion stability, buffer devices 5 are provided at both the upper and lower limit positions of the vertical motion module 1. These buffer devices 5 can be polyurethane buffer pads or hydraulic dampers, used to absorb impact energy at the moving end, reduce noise, and protect the mechanism.

[0041] Working principle

[0042] In the initial state, the end effector 3 is in the initial high position, and the rotary module 2 is in the 0-degree position, i.e., the initial angular position. During descent and gripping, the servo motor 11 starts and drives the motion platform to move downward along the vertical guide rail 13 through the transmission component 12, causing the end effector 3 to descend to the material handling station. After reaching the predetermined position, the pneumatic gripper 33 actuates, its chuck closes, and reliably grips the workpiece.

[0043] During lifting and rotation, the vertical motion module 1 raises the workpiece to a safe height. Then, the rotary cylinder 22 actuates, driving the output shaft 23 and the end effector 3 to rotate by a predetermined angle, such as 90° or 180°, moving the workpiece from the pick-up station to above the unloading station. The vertical motion module 1 then drives the end effector 3 to descend, delivering the workpiece to the unloading station, such as a conveyor belt or tray. The pneumatic gripper 33 releases, accurately releasing the workpiece. Upon return, the end effector 3 rises unloaded, and the rotary cylinder 22 drives it to rotate in the opposite direction back to the initial 0-degree angle position, preparing for the next pick-up and unloading cycle.

[0044] Throughout the entire operation, the auxiliary support structure formed by the connecting sleeve 31 and the bracket 32 ​​significantly improves the rigidity and stability during rotational motion, ensuring positioning accuracy under high-cycle operation. The servo motor 11 provides precise Z-axis position control, while the rotary cylinder 22 provides rapid and angularly accurate horizontal rotational motion. Working together, they achieve efficient, smooth, and precise material discharge operations, making them particularly suitable for modern intelligent manufacturing scenarios with high automation and fast production cycles.

[0045] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
