Description

Technical Field

[0001] The utility model relates to the technical field of robot bases, in particular to a portable robot insulating base. Background Art

[0002] With the rapid development of industrial automation, portable robots are increasingly used in welding, assembly and other fields. However, in actual use, the connection between the robot base and the robot often leads to short circuit problems due to good conductivity, which not only greatly reduces the robot's work efficiency, but also poses a potential threat to the safety of operators. Therefore, how to effectively solve this problem and ensure the stable operation and safe operation of the robot has become a technical problem that needs to be solved urgently.

[0003] Specifically, when the welding gun contacts the workpiece for welding, the current should flow back to the power supply through the welding gun, the workpiece, and the ground clamp to form a normal working circuit. However, if the insulation measures between the robot base and the robot are insufficient, the current may "leak" to the base and enter the robot body through the connecting cable. In this way, the current no longer flows along the expected path, but forms an unexpected closed loop between the welding gun, the workpiece, the robot base, the robot body, the connecting cable, and the ground clamp, which may cause a short circuit problem.

[0024] In this embodiment, please refer to Figure 2-3The peristaltic pump 3 includes a fixed seat 31 and a servo motor 32. The output end of the servo motor 32 is fixedly connected to a driving shaft 33. An extrusion block 34 is arranged on the outer side of the driving shaft 33. A hose 35 is arranged on the inner wall of the fixed seat 31. The driving shaft 33 is located in the inner cavity of the fixed seat 31, and one side of the extrusion block 34 is transitionally matched with the outer side of the hose 35. In this embodiment, when the servo motor 32 drives the driving shaft 33 to rotate at a high speed, due to the transitional match between the extrusion block 34 and the outer side of the hose 35, the extrusion block 34 continuously squeezes the outer side of the hose 35, so that positive pressure is generated at one end of the hose 35 and negative pressure is generated at the other end.

[0025] In this embodiment, please refer to Figure 2 The short-circuit self-detection device 221 also includes a protection module. After receiving the alarm signal from the data processing module, the protection module immediately cuts off the relevant circuit. In this embodiment, after receiving the alarm signal from the data processing module, the protection module immediately cuts off the relevant circuit to prevent a short circuit from occurring.

[0026] In this embodiment, please refer to Figure 1 , Figure 3 A sealing ring 215 is provided on the inner wall of the insulating sleeve 214, and a waterproof and anti-fouling coating is coated on the surface of the robot base 2. The coating is made of a nano-polymer composite material. In this embodiment, liquid is prevented from penetrating through the gap between the robot body 1 and the robot base 2, thereby further improving the insulation effect between the robot body 1 and the robot base 2. At the same time, the waterproof and anti-fouling coating can effectively resist the erosion of water, oil and other stains, ensuring that the base is always kept clean. At the same time, its good insulation performance can maintain the electrical safety of the base.

[0027] In this embodiment, please refer to Figure 2 A sound and light alarm 222 is also provided on one side of the fixing frame 22. The sound and light alarm 222 is electrically connected to the data processing module. In this embodiment, the data transmission module receives the data of the current detection module, and performs comprehensive analysis and judgment. If abnormal data is detected, the data processing module triggers the sound and light alarm 222, so that the sound and light alarm 222 emits a sound and light alarm to prompt the staff.

[0028] In this embodiment, please refer to Figure 2 , Figure 4 One end of the hose 35 penetrates into the inner cavity of the suction cup 4, a vent hole 231 is opened on one side of the bottom plate 23, and the other end of the hose 35 is located in the inner cavity of the vent hole 231.

[0030] Working principle of this utility model:

[0031] Step 1: An insulating plate 213 is provided on the top of the mounting seat 21, and an insulating sleeve 214 is provided at the connection portion between the robot body 1 and the mounting seat 21. The insulating plate 213 and the insulating sleeve 214 are used to prevent the metal parts of the robot body 1 and the robot base 2 from contacting each other, and to prevent the current from flowing through the metal parts of the robot body 1 and the robot base 2, thereby isolating the electrical connection between the robot body 1 and the robot base 2. At the same time, the current detection module is responsible for real-time monitoring of the current value between the welding gun, the workpiece, the robot base, the robot body, the connecting cable, and the grounding clamp. When the current value exceeds the preset threshold, it is considered that a short circuit may exist. The data processing module receives the data from the current detection module and the insulation detection module, and performs a comprehensive analysis and judgment. If abnormal data is detected, the data processing module will trigger the sound and light alarm 222 and notify the protection module. After receiving the alarm signal from the data processing module, the protection module will immediately cut off the relevant circuit to prevent the short circuit from causing further damage to the robot system.

[0032] Step 2: The servo motor 32 is used to provide power to control the high-speed rotation of the drive shaft 33. Since the drive shaft 33 is located in the inner cavity of the fixing seat 31, when it rotates at a high speed, the two extrusion blocks 34 will continuously squeeze the outer side of the hose 35, causing the outer side of the hose 35 to continuously deform, and then restore to its original state due to its own elasticity, so that one end of the hose 35 generates positive pressure to discharge air, and the other end generates negative pressure to inhale air, so that the hose 35 continuously extracts the gas in the inner cavity of the suction cup 4, and discharges the air to the outside through the vent 231. The suction cup 4 is in contact with the work surface, and its inner cavity forms a closed space. When the air in the inner cavity is pumped out, negative pressure is formed under the external atmospheric pressure, so that the robot body 1 and the robot base 2 can be fixed on the work surface through the suction cup 4. The servo motor 32 controls the drive shaft 33 to reverse, so that the air intake end and the air outlet end of the hose 35 are reversed, and the hose 35 inhales the outside air through the vent 231 and injects it into the inner cavity of the suction cup 4, so that the internal air pressure of the suction cup 4 returns to normal, and the robot base 2 can be released from the work surface.
