Description

Technical Field

[0001] This invention belongs to the field of robot accessories technology, and in particular relates to a base for extending the life of robot pipelines. Background Technology

[0002] Robot pipelines are primarily responsible for transmitting power and control signals to ensure that all components of the robot can operate normally and work collaboratively. As an important component of the robot pipeline system, the robot pipeline base plays a crucial role in supporting, fixing, and protecting the pipelines, as well as connecting external equipment and internal pipelines.

[0003] Currently, the robot pipeline base serves as a bridge connecting external power supply circuits and various electrical components of the robot, and its stability is very important. External power supply circuits are usually connected to the base, and then connected to the cables on the robot through the lower adapter on the base. The base is usually installed on the lower side wall of the robot and rotates synchronously with the robot, such as the base for extending the life of robot pipelines disclosed in patent publication number CN107571287A.

[0004] Robot cable packages typically contain various cables converging through corrugated protective tubes. While these tubes protect the cables, they can cause wear and tear during robot rotation due to friction with the robotic arm and other components. Furthermore, during tasks like welding, sparks can easily splatter onto the tubes. Excessive wear and spark exposure can create defects such as holes in the tubes. If these defects are not detected promptly, they can damage the cables inside the tubes, impacting the robot's cable lifespan. Summary of the Invention

[0015] Compared to existing technologies, the advantages of a base that extends the lifespan of robot pipelines are:

[0016] 1. Through the coordinated design of the ring-shaped fixed base, ring-shaped movable base, guide rail groove, guide rail slider, wiring hole, lower adapter mechanism, sealing sleeve, cover plate, cable receptacle, corrugated pipe, and upper adapter mechanism, the robot cable can be protected. Furthermore, thanks to the double-layer rotatable base structure, when the robot turns horizontally, excessive pulling on the cable can be avoided, thereby reducing the probability of cable damage.

[0017] 2. Through the coordinated operation of the air supply mechanism, sealing cover, vent, triggering mechanism, and control mainboard, regular damage detection of the bellows can be performed. This allows personnel to promptly identify any damage to the bellows and reduces the impact of excessive wear on cable lifespan. Furthermore, filling the bellows with an appropriate amount of air, creating an internal pressure higher than the external pressure, enhances its impact resistance. Combined with the included heat dissipation mechanism, this cools the robot cables during operation, preventing heat buildup and slowing down cable aging, further extending the robot's cable lifespan.

[0018] 3. Through the coordinated operation of the support sleeve, lower limit ring, upper limit ring, movement detection mechanism and maintenance measurement mechanism, the distance traveled during the overall rotation of the robot can be automatically triggered based on the rotational motion, thereby timely reminding personnel to perform maintenance on the lower transfer mechanism.

The control motherboard 17 and the robot cable are electrically connected to the corresponding lower adapter 62. The side wall of the annular fixed base 1 is provided with a special wiring socket (not shown in the figure) for connecting the external power supply line to the electrode ring 66. Each elastic support component 68 includes an insulating cylinder, an insulating column, and an elastic element. The conductive head 67 is located at the end of the insulating column, and the insulating column slides and extends inside the insulating cylinder. The elastic element is located between the insulating column and the insulating cylinder to apply pressure to the conductive head 67, so that the conductive head 67 and the electrode ring 66 are stably in contact.

[0029] A sealing sleeve 7 is fixedly connected to the end face of the annular movable base 2 above the wiring hole 5. A removable cover plate 8 is installed on the end face of the sealing sleeve 7. A coil connector 9 is fixedly inserted into the end face of the cover plate 8. The cover plate 8 also has a through hole for pipes (such as pipes for transporting water or gas) that are needed on the robot. After the pipe passes through the through hole, the hole wall between the pipe and the through hole needs to be sealed. A removable corrugated pipe 10 is installed on the coil connector 9. An upper adapter mechanism 1 is installed on the end of the corrugated pipe 10. 1. The upper adapter mechanism 11 includes an upper mounting plate 111 disposed at one end of the bellows 10 away from the annular movable base 2, and the upper mounting plate 111 is detachably connected to the bellows 10. Multiple upper adapters 112 are fixedly inserted into the end face of the upper mounting plate 111. Each upper adapter 112 is electrically connected to the corresponding lower adapter 62 through a corresponding robot cable. One end of the upper adapter 112 is used to connect to the robot cable, and the other end is also connected to various electrical components (such as various sensors) on the robot through a cable.

[0030] An air supply mechanism 12 is installed on the side wall of the sealing sleeve 7. The air supply mechanism 12 includes an air pump 121 fixedly installed on the outer side wall of the sealing sleeve 7. The suction end of the air pump 121 is fixedly connected to the suction pipe 122, and the output end of the air pump 121 is fixedly connected to the air delivery pipe 123. The air pump 121 is electrically connected to the control main board 17. When the air pump 121 is working, it can draw in external air through the suction pipe 122 and output it through the air delivery pipe 123.

[0031] A sealing cover 13 is fixedly connected to the outer wall of the sealing sleeve 7, and two vent holes 14 communicating with the sealing cover 13 are opened on the side wall of the sealing sleeve 7. A triggering mechanism 15 is provided inside the sealing cover 13. The triggering mechanism 15 includes a fixing block 151 fixedly installed inside the sealing cover 13, and two circular grooves 152 are opened at the end of the fixing block 151. A transparent plate 153 is fixedly attached to the groove wall facing the other side of the two circular grooves 152. A piston 154 is slidably installed inside each of the two circular grooves 152. A support spring 155 is fixedly installed between each of the two pistons 154 and the outer wall of the sealing sleeve 7. The side wall facing the other side of the two pistons 154 is fixedly attached to the sealing cover 153. The device has fixed slots 156, one of which houses an LED 157, and the other of which houses a photoelectric switch 158. The light emitted by the LED 157 can pass through the transparent plate 153 and illuminate the photoelectric switch 158. A first normally open solenoid valve 159 is installed inside one of the circular slots 152, and the first normally open solenoid valve 159 is on the same side as the LED 157. The LED 157, the photoelectric switch 158, and the first normally open solenoid valve 159 are all electrically connected to the control main board 17. The photoelectric switch 158 can convert light signals into electrical signals, which is a mature existing technology and will not be described in detail here.

[0032] The upper adapter 11, the air supply mechanism 12, and the sealing sleeve 7 are all equipped with a heat dissipation mechanism 16. The inner wall of the sealing sleeve 7 is fixedly installed with a control main board 17. The heat dissipation mechanism 16 includes a ventilation hose 161, and the ventilation hose 161 is detachably connected to the air supply pipe 123. A U-shaped block 162 is fixedly installed on the end face of the upper mounting plate 111, and the U-shaped block 162 is located inside the corrugated pipe 10. The end of the ventilation hose 161 away from the air supply pipe 123 passes through the side wall of the U-shaped block 162. The side wall of the sealing sleeve 7 is provided with an exhaust hole 163, and an electrically controlled valve 164 electrically connected to the control main board 17 is installed inside the exhaust hole 163. The ventilation hose 161 has a certain tensile strength.

[0033] A support sleeve 18 is fixedly installed on the outer edge of the end face of the annular fixed base 1. The support sleeve 18 has a lower limit ring 19 inside, and the lower limit ring 19 is fixedly sleeved on the outside of the annular movable base 2. An upper limit ring 20 is provided above the lower limit ring 19, and the upper limit ring 20 is detachably connected to the support sleeve 18. The lower limit ring 19 and the annular fixed base 1 are jointly equipped with a moving detection mechanism 21. The suction pipe 122 is equipped with a maintenance measurement mechanism 22. The moving detection mechanism 21 is electrically connected to the maintenance measurement mechanism 22 through the control motherboard 17. By blocking the lower limit ring 19 through the upper limit ring 20, the annular movable base 2 can be restricted to prevent the annular movable base 2 from detaching from the annular fixed base 1.

[0034] The mobile detection mechanism 21 includes a circular sleeve 211 fixedly installed at the bottom of the lower limit ring 19. A connecting ring 212 is fixedly installed inside the circular sleeve 211, and an insulating impact rod 213 is slidably connected to the connecting ring 212. A compression hemisphere 214 is fixedly connected to the lower end of the insulating impact rod 213, and a return spring 215 is fixedly provided between the compression hemisphere 214 and the connecting ring 212. Multiple pressing columns 216 are fixedly installed on the end face of the annular fixed base 1, and each pressing column 216 is evenly distributed in a ring about the axis of the annular fixed base 1. The length of each pressing column 216 is greater than the distance between the bottom of the compression hemisphere 214 and the annular fixed base 1. Inside the sleeve 211, a piezoelectric ceramic component 217 is installed, and the insulating impact rod 213 is in contact with the end face of the piezoelectric ceramic component 217. An electromagnetic switch 218 is fixedly installed at one end of the lower limit ring 19 inside the sleeve 211. The piezoelectric ceramic component 217 is electrically connected to the electromagnetic switch 218 through the control motherboard 17. When the piezoelectric ceramic component 217 is squeezed, the polarization direction of its grains changes, and the centers of positive and negative charges no longer coincide. Equal numbers of bound charges with opposite signs appear on the two surfaces perpendicular to the stress, thereby generating a voltage. Through the circuit connection with the control motherboard 17, the movement of these charges generates a current.

[0035] The maintenance metering mechanism 22 includes a branch suction pipe 221 fixedly inserted into the wall of the suction pipe 122. A detachable gas flow meter 222 is installed on the inner side wall of the branch suction pipe 221, and the detection end of the gas flow meter 222 is located inside the branch suction pipe 221. A normally closed solenoid valve 223 is installed inside the branch suction pipe 221, and a second normally open solenoid valve 224 is installed inside the suction pipe 122. The branch suction pipe 221 is located between the second normally open solenoid valve 224 and the air pump 121. The electromagnetic switch 218 is electrically connected to the second normally open solenoid valve 224 and the normally closed solenoid valve 223 through the control main board 17. The gas flow meter 222 is electrically connected to the control main board 17. The gas flow meter 222 can calculate the gas flow rate and output an electrical signal to the control main board 17 after the total gas flow rate reaches the set value. This is a mature existing technology, so it will not be described in detail here.

[0036] The operating principle of this invention is explained as follows: The annular movable base 2 is moved to the annular fixed base 1, and each insulating strip 63 is inserted into the corresponding annular groove 64. Then, the upper limit ring 20 is installed on the support sleeve 18. The robot's cables are then connected to the upper adapters 112 on the upper mounting plate 111. Next, the cables are passed through the corrugated pipe 10, and the upper mounting plate 111 and the corrugated pipe 10 are secured together. After that, the cables are passed through the cable reel connector 9 on the cover plate 8, and the cables are connected to the lower adapters 62. Connect the cover plate 8 and the sealing sleeve 7, then fix the cover plate 8 on the sealing sleeve 7 and fix it. Connect each set of electrode rings 66 inside the annular fixed base 1 to the external power supply line (the side wall of the annular fixed base 1 is provided with a special wiring socket for the connection between the external power supply line and the electrode rings 66, which is not shown in the figure). The external power supply line supplies power to the robot cable and the control motherboard 17 through each electrode ring 66 and the conductive head 67. When the robot is started to work, the control motherboard 17 is started.

[0037] After the main control board 17 starts, it immediately controls the air pump 121 to work for 30 seconds at a set time and controls the electric control valve 164 inside the exhaust port 163 to be energized and closed. At this time, the air pump 121 will fill a certain amount of air into the sealing sleeve 7 and the bellows 10 through the air supply pipe 123. Under the action of the filled air, the internal air pressure of the bellows 10 and the sealing sleeve 7 will increase. Under the action of the increased air pressure, the pistons 154 inside the two circular grooves 152 will be pushed to the end away from the sealing sleeve 7. Since the first normally open solenoid valve 159 is not energized, the air pressure inside the two circular grooves 152 is the same, so the two pistons 154 will be pushed away from the sealing sleeve 7. 54 are pushed the same distance. After the air pump 121 finishes its timed operation, the control board 17 will control the first normally open solenoid valve 159 to be energized for 40 seconds. At this time, the space between the groove 152 at the lamp bead 157 and the inside of the sealing sleeve 7 is separated, while the groove 152 at the photoelectric switch 158 and the inside of the sealing sleeve 7 remain connected. When the control board 17 starts the first normally open solenoid valve 159 to work for 30 seconds, the control board 17 will start the lamp bead 157. If the bellows 10 is damaged due to wear or other reasons, the excess air inside the bellows 10 will escape through the damaged area. Therefore, the bellows... The air pressure inside tube 10 and sealing sleeve 7 will gradually decrease. At this time, the piston 154 at photoelectric switch 158 will move back under the action of support spring 155. Therefore, when the control board 17 starts the lamp bead 157, the two pistons 154 will be misaligned. Thus, the light emitted by the lamp bead 157 cannot pass through the transparent plate 153 to reach the photoelectric switch 158. Therefore, the control board 17 will not receive the electrical signal from the photoelectric switch 158. If the control board 17 still does not receive the electrical signal from the photoelectric switch 158 after the lamp bead 157 has been working for 5 seconds, the control board 17 will activate its own alarm module (e.g., (e.g., a buzzer) to alert staff that the bellows 10 may be damaged. Conversely, if the bellows 10 is not damaged, the air inside the bellows 10 will not escape. At this time, the positions of the two pistons 154 will not be misaligned. Therefore, the light emitted by the lamp bead 157 will shine through the transparent plate 153 to the photoelectric switch 158. After receiving the light signal, the photoelectric switch 158 will convert the light signal into an electrical signal and output it to the control board 17. After receiving the electrical signal from the photoelectric switch 158, the control board 17 will not activate its own alarm module.

[0038] After the first normally open solenoid valve 159 finishes its timed operation, the control board 17 will restart the air pump 121 and de-energize the solenoid valve 164. At this time, the solenoid valve 164 will open, and the air pump 121 will deliver airflow through the air supply pipe 123 and the ventilation hose 161 to the side of the bellows 10 near the upper mounting plate 111. Then the airflow will flow in the opposite direction through the bellows 10 and finally be discharged through the exhaust port 163 of the sealing sleeve 7. Under the action of airflow, the robot cable inside the bellows 10 can be cooled down, which can prevent the heat from accumulating in the cable and thus accelerate the aging of the cable and the bellows 10, and help improve the service life of the robot pipeline.

[0039] When the robot is working, if the main body of the robot (i.e., the robotic arm) rotates horizontally by 360°, the robot will pull the annular movable base 2 through the bellows 10, cover plate 8, and sealing sleeve 7. At this time, the annular movable base 2 will slide along the guide rail groove 3 through the guide rail slider 4 due to the pulling force. When the annular movable base 2 slides, it will drive each conductive head 67 to move against each electrode ring 66 through the insulating strip 63, so as not to affect the power supply of the external power supply circuit to the robot cable and control motherboard 17. At the same time, there will be no mutual pulling and dragging between the robot cable and the external power supply circuit, reducing the possibility of damage to the robot cable. When the annular movable base 2 rotates, it will pull through the circular sleeve 211, insulating impact rod 213, and connecting ring. 212 drives the extrusion hemisphere 214 to move. When the extrusion hemisphere 214 passes each pressure column 216, it is blocked by the pressure columns 216. The pressure columns 216 then push the insulating impact rod 213 upwards through the extrusion hemisphere 214, causing the insulating impact rod 213 to press against the piezoelectric ceramic component 217. This changes the polarization direction of the grains in the piezoelectric ceramic component 217, and the centers of positive and negative charges no longer coincide. Equal numbers of bound charges with opposite signs appear on the two surfaces perpendicular to the stress, generating a voltage. Through circuit connection with the control motherboard 17, the movement of these charges generates current. The control motherboard 17 amplifies this current signal and sends it into the electromagnetic switch 218, energizing and closing the electromagnetic switch 218. This energizes the second normally open solenoid valve 224 and the normally closed solenoid valve 223. Under the action of the delay-off module on the control board 17, the second normally open solenoid valve 224 and the normally closed solenoid valve 223 are de-energized after a 1-second delay. At this time, the suction end of the air pump 121 draws in external air through the suction pipe 122 and the branch suction pipe 221. The gas flow meter 222 calculates the flow rate of the drawn-in air. When the squeeze hemisphere 214 moves away from a certain pressure column 216, the piezoelectric ceramic component 217 rebounds due to its own elastic recovery. When it moves to the next pressure column 216, the piezoelectric ceramic component 217 is squeezed again, generating an electrical signal. The electromagnetic switch 218 closes again, causing the second normally open solenoid valve 224 and the normally closed solenoid valve 223 to de-energize. Valve 223 remains energized until the annular movable base 2 stops moving. At this point, the piezoelectric ceramic component 217 has two states: First, the extruded hemisphere 214 is not in contact with the top pressure column 216, and the piezoelectric ceramic component 217 remains flat. In this state, the charge on the piezoelectric ceramic component 217 returns to a uniform distribution, so it does not generate an electrical signal. At this time, the moving contact of the electromagnetic switch 218 disconnects, and the second normally open solenoid valve 224 and the normally closed solenoid valve 223 are also de-energized after a 1-second delay. Second, the extruded hemisphere 214 is in contact with the top pressure column 216, and the piezoelectric ceramic component 217 remains deformed. In this state, because the piezoelectric ceramic component 217 continues to be deformed, the charge inside it is redistributed.Once the charge distribution reaches equilibrium, there will be no more continuous charge flow. Therefore, the electrical signal of the piezoelectric ceramic component 217 will also be disconnected, and the second normally open solenoid valve 224 and normally closed solenoid valve 223 will also be de-energized. That is, when the annular movable base 2 rotates and moves along the annular fixed base 1, the piezoelectric ceramic component 217 is subjected to continuous compression, keeping the second normally open solenoid valve 224 and normally closed solenoid valve 223 energized. When the annular movable base 2 stops rotating and moving, the second normally open solenoid valve 224 and normally closed solenoid valve 223 remain de-energized. Because the annular movable base 2 moves... This will cause relative movement between the conductive head 67 and the electrode ring 66, resulting in some wear between them. To ensure stable power supply, maintenance (such as replacing the conductive head 67) is required between the conductive head 67 and the electrode ring 66. By introducing air through the suction pipe 221 when relative movement occurs between the conductive head 67 and the electrode ring 66, and measuring it through the gas flow meter 222, the relative displacement distance between the conductive head 67 and the electrode ring 66 can be calculated. When the gas flow meter 222 reaches the set flow rate (e.g., the total gas flow reaches 1m), the relative displacement distance between the conductive head 67 and the electrode ring 66 can be measured. 3 When the gas flow meter 222 outputs an electrical signal to the control board 17, the control board 17 will then send an alarm notification to the staff through its own alarm module (this alarm notification method is different from the alarm method when the bellows 10 is damaged, such as an audible and visual alarm).
