Technical Field

[0001] This utility model relates to the field of gearbox mounting plate processing, specifically a gearbox mounting plate processing robot. Background Technology

[0002] A robotic arm is an automated device that can mimic certain movements and functions of a human hand and arm to grasp, move objects, or operate tools according to a fixed program. Robotic arms were the earliest industrial robots and the first modern robots to emerge. They can replace heavy human labor to achieve mechanization and automation of production, and can operate in hazardous environments to protect human safety. Therefore, they are widely used in machinery manufacturing, metallurgy, electronics, light industry, and nuclear energy sectors.

[0003] During the processing of the gearbox mounting plate, a robotic arm is required for loading and unloading the plate. However, existing robotic arms, after unloading the already processed workpiece, need to re-grab the workpiece to be processed and position it back onto the processing equipment. This sequential operation mode results in waiting time for the equipment, hindering further improvement in overall production efficiency. Therefore, a new technical solution needs to be designed to address this issue. Utility Model Content

Exhaust groove. Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0027] Example 1: A robotic arm for processing gearbox mounting plates, see [link / reference] Figures 1 to 3 ,include:

[0028] A rotating assembly is mounted on the end effector of the robotic arm 1;

[0029] The rotating component includes:

[0030] Mounting plate 23, a rotary drive mechanism 22 is provided on one side of the mounting plate 23;

[0031] The support plate 24 is rotatably mounted on one side of the mounting plate 23 and connected to the drive end of the rotary drive mechanism 22;

[0032] The gripping component is located on the side of the support plate 24 away from the mounting plate 23. The gripping component can rotate around the drive end of the rotary drive mechanism 22 to realize the switching of work positions. The rotary drive mechanism 22 is a drive motor, which is fixedly connected to the side of the mounting plate 23 away from the support. The drive end of the drive motor rotates through the mounting plate 23 and is fixedly connected to the support plate 24.

[0033] This device, through its rotary drive mechanism 22 and gripping components, achieves the following during use:

[0034] High efficiency of workstation switching: The gripping component can rotate around the drive end of the rotary drive mechanism 22. After gripping the workpiece on the processing station, the processing station and the loading / unloading station rotate to switch positions, so that the workpiece to be processed on the loading / unloading station corresponds to the processing position, realizing rapid switching between the processing station and the loading / unloading station, eliminating the waiting time of traditional serial operations.

[0035] High space utilization: The rotating connection between the support plate 24 and the mounting plate 23 reduces the risk of interference in the movement path of the robot arm, making it suitable for compact production line layouts.

[0036] For details, see Figure 2 The gripping assembly includes two support bases 27 and a vacuum suction cup 28 fixedly connected to one end of the support base 27. A vacuum pump 25 is fixedly connected to one end of the support base 27, and a connecting pipe 26 connects the vacuum pump 25 and the vacuum suction cup 28. The mounting plate 23 and the bearing plate 24 on the support base 27 are set at 45°. The two support bases 27 and the vacuum suction cup 28 fixedly connected to one end of the support base 27 form a dual-station parallel operation. The two support bases 27 cooperate with the vacuum suction cup 28 to simultaneously grip the workpiece to be processed and the processed workpiece, realizing "synchronous pick-up and drop", which greatly improves production efficiency. The vacuum pump 25 is designed to ensure stable adsorption force and avoid pressure loss caused by long-distance transmission of traditional air circuits. In addition, the connecting pipe 26 is equipped with a pressure relief valve for depressurizing the vacuum suction cup 28 to ensure that the gripped workpiece can be released from the vacuum suction cup 28.

[0037] Further, see Figure 2 An air hood is fixedly connected to the middle of one end of the support base 27 near the vacuum suction cup 28. A blower is fixedly installed at the bottom of the support base 27. The air outlet of the blower is connected to the air hood through a flexible tube. When the support base 27 moves downward, the blower is activated to form a directional airflow through the air hood, which blows away the debris on the surface of the workpiece before gripping, so as to avoid the debris affecting the firmness of the vacuum suction cup 28 in gripping the workpiece.

[0038] It is worth noting that, see Figure 1 and Figure 2 A telescopic assembly is provided between the end effector of the robotic arm 1 and the mounting plate 23. The telescopic assembly includes a telescopic motor 2 fixedly connected to the end effector of the robotic arm. The drive end of the telescopic motor 2 is fixedly connected to a connecting plate 21. One end of the connecting plate 21 is fixedly connected to the end of the mounting plate 23 away from the bearing plate 24. The telescopic motor 2 allows the robotic arm to finely adjust the gripping height according to the workpiece position, adapting to fixed plates of different thicknesses or stacking states. In addition, in narrow spaces, it can avoid clamps or processing tools by retracting, reducing the risk of collision. It can also adapt to the differences in workpiece feeding and feeding heights of various processing equipment (such as milling machines and drilling machines).

[0039] It is worth noting that, see Figure 2The telescopic motor 2 has a trigger assembly 3 on its housing near the mounting plate 23. A push-button power-off switch 31 is fixedly connected to the end of the connecting plate 21 near the trigger assembly 3. The push-button power-off switch 31 is electrically connected to the blower via a power supply through a wire. When the support base 27 moves downward, the push-button power-off switch 31 disengages from the trigger assembly 3 and is energized, thereby automatically starting the blower to clean the debris on the surface of the gripped workpiece. When the gripped workpiece moves upward, the sleeve 33 contacts the push-button power-off switch 31 and automatically shuts off the blower, reducing unnecessary energy consumption.

[0040] It is worth mentioning that, see Figure 3 The triggering component 3 includes a connecting rod 32 fixedly connected to the housing of the telescopic motor 2. A sleeve 33 is slidably sleeved on the outer side of the connecting rod 32. The sleeve 33 corresponds to the push-button power-off switch 31. A buffer spring 34 is fixedly connected to the bottom end of the inner cavity of the sleeve 33. The other end of the buffer spring 34 is fixedly connected to the connecting rod 32. When the sleeve 33 contacts the push-button power-off switch 31, the spring compression buffers the impact force of the contact between the sleeve 33 and the push-button power-off switch 31, reducing the instantaneous impact on the push-button power-off switch 31. In addition, it avoids rigid collisions that could cause deformation of the switch or the sleeve 33, thus improving the durability of the component.

[0041] It is worth mentioning that, see Figure 3 The sleeve 33 has limit grooves 35 at both ends of its inner cavity. Limit blocks 36 are slidably connected in both limit grooves 35. The limit blocks 36 are fixedly connected to the connecting rod 32. The limit blocks 36 and the limit grooves 35 cooperate to prevent the sleeve 33 from detaching from the connecting rod 32, thus ensuring long-term stability.

[0042] It is worth mentioning that, see Figure 3 The connecting rod 32 has an exhaust groove 37 on one side. The exhaust groove 37 balances the air pressure inside and outside the sleeve 33, eliminating the sliding lag caused by negative pressure.

[0043] In addition, all components designed in this utility model are general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

[0044] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
