Description

Technical Field

[0001] The invention belongs to the technical field of robot accessories, and in particular relates to a base for extending the service life of robot pipelines. Background Art

[0002] The robot pipeline is mainly responsible for transmitting power, control signals, etc. to ensure that the various components of the robot can operate normally and work together. The robot pipeline base, as an important part of the robot pipeline system, has the important functions of supporting, fixing, protecting the pipeline and connecting external equipment and internal pipelines.

[0003] At present, the robot pipeline base is used as a connecting bridge between the external power supply circuit and various electrical components of the robot. Its stability is very important. The external power supply circuit is usually connected to the base, and then connected to the cable on the robot through the lower adapter on the base. The base is usually installed at the lower end of the side wall of the robot and rotates synchronously with the robot. For example, patent publication number CN107571287A discloses a base for extending the life of the robot pipeline;

[0004] The robot pipeline package usually collects various cables through a corrugated protective tube. The corrugated protective tube can be used to protect the cables. However, during the torsion of the robot, the corrugated protective tube is prone to contact and rub against the robot arm and other parts, causing the corrugated protective tube to wear. Secondly, when performing work such as welding, welding sparks are also easy to splash onto the corrugated protective tube. The corrugated tube may have defects such as holes in the location of excessive wear and spark splashing. If not discovered in time, the cables inside the corrugated tube may also be damaged, affecting the service life of the robot pipeline. Summary of the invention

[0015] Compared with the existing technology, the advantages of a base that extends the life of the robot pipeline are:

[0016] 1.

In addition, with the double-layer rotatable base structure, when the robot turns horizontally as a whole, excessive pulling on the cables can be avoided, thereby reducing the probability of cable damage.

Through the coordination of the air supply mechanism, sealing cover, vent, trigger mechanism and control mainboard, the damage detection of the bellows can be carried out regularly, which is beneficial for personnel to know the damage of the bellows in time and reduce the impact of excessive wear of the bellows on the service life of the cable.

[0018] 3.

The photoelectric switch 158 can convert optical signals into electrical signals. This is an existing mature technology, so it will not be elaborated here.

[0032] The upper adapter mechanism 11, the air supply mechanism 12 and the sealing sleeve 7 are jointly equipped with a heat dissipation mechanism 16, and a control main board 17 is fixedly installed on the inner wall of the sealing sleeve 7. The heat dissipation mechanism 16 includes a ventilation hose 161, and the ventilation hose 161 is detachably connected to the air pipe 123.

Equal amounts of bound charges with opposite signs will appear on the two surfaces perpendicular to the stress, thereby generating a voltage.

[0036] The operating principle of the present invention is now described 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, and each cable of the robot is connected to each upper adapter 112 on the upper mounting plate 111, then each cable is passed through the corrugated tube 10, and the upper mounting plate 111 and the corrugated tube 10 are fixed by a sleeve, and then each cable is passed through the wire wrap tube 9 on the cover plate 8, and each cable is connected to each lower adapter 62 Then, the cover plate 8 and the sealing sleeve 7 are fixed by clamping, and the cover plate 8 is covered on the sealing sleeve 7 and fixed, and each group of electrode rings 66 inside the annular fixed base 1 is connected with the external power supply line (the side wall of the annular fixed base 1 is provided with a special wiring socket for connecting the external power supply line with the electrode ring 66, and the wiring socket is not shown in the figure), and the external power supply line supplies power to the robot cable and the control mainboard 17 through each electrode ring 66 and the conductive head 67. When the robot is started to work, the control mainboard 17 is started;

[0037] After the control main board 17 is started, it will immediately control the air pump 121 to work for 30 seconds, and control the electric control valve 164 inside the exhaust hole 163 to be powered on and closed. At this time, the air pump 121 will fill a fixed amount of air into the sealing sleeve 7 and the bellows 10 through the air delivery 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 powered on, the air pressure inside the two circular grooves 152 is the same, so the two pistons 1 54 is pushed the same distance, and after the air pump 121 finishes its scheduled operation, the control mainboard 17 controls the first normally open solenoid valve 159 to be energized for 40 seconds. At this time, the circular groove 152 at the lamp bead 157 is separated from the space inside the sealing sleeve 7, while the circular groove 152 at the photoelectric switch 158 is still connected to the inside of the sealing sleeve 7. When the control mainboard 17 starts the first normally open solenoid valve 159 to work for 30 seconds, the control mainboard 17 starts the lamp bead 157. If the bellows 10 is damaged due to wear and tear, the excess air inside the bellows 10 will escape through the damaged part. Therefore, the bellows The air pressure inside the tube 10 and the sealing sleeve 7 will gradually decrease. At this time, the piston 154 at the photoelectric switch 158 will move back under the action of the supporting spring 155. Therefore, when the control mainboard 17 starts the lamp bead 157, the two pistons 154 will stagger, so the light emitted by the lamp bead 157 cannot pass through the transparent plate 153 to irradiate the photoelectric switch 158. Therefore, the control mainboard 17 will not receive the electrical signal of the photoelectric switch 158. After the lamp bead 157 works for 5 seconds, if the control mainboard 17 still does not receive the electrical signal of the photoelectric switch 158, the control mainboard 17 will start its own alarm module (for example, The bellows 10 may be damaged. On the contrary, 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, so the light emitted by the lamp bead 157 will pass 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 main board 17. After receiving the electrical signal from the photoelectric switch 158, the control main board 17 will not activate its own alarm module.

[0038] After the first normally open solenoid valve 159 finishes its timed operation, the control main board 17 will start the air pump 121 again and control the electric control valve 164 to cut off the power. At this time, the electric control valve 164 is open, and the air delivered by the air pump 121 will pass through the air delivery pipe 123 and the ventilation hose 161 to the side of the inner part of the bellows 10 close to 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 hole 163 of the sealing sleeve 7. Under the flow of the airflow, the robot cable inside the bellows 10 can be cooled and cooled, thereby avoiding the heat that cannot be dissipated in time due to the accumulation of cables, thereby accelerating the aging of the cables and the bellows 10, and helping to improve the service life of the robot pipeline.

[0039] When the robot is working, if the main body of the robot (i.e., the robot arm) performs a 360° horizontal rotation as a whole, the robot will pull the annular movable base 2 through the bellows 10, the cover plate 8, and the 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, and when the annular movable base 2 slides, it will drive each conductive head 67 to move along each electrode ring 66 through the insulating strip 63, thereby not affecting the power supply of the robot cable and the control main board 17 by the external power supply circuit. At the same time, there will be no mutual pulling and dragging between the robot cable and the external power supply circuit, thereby reducing the possibility of damage to the robot cable. When the annular movable base 2 rotates, it will be connected to the robot cable through the circular sleeve 211, the insulating impact rod 213, and the connecting ring 212 drives the squeezing hemisphere 214 to move. At this time, when the squeezing hemisphere 214 passes through each top pressure column 216, it will be blocked by the top pressure column 216. At this time, the top pressure column 216 will squeeze the insulating impact rod 213 upward through the squeezing hemisphere 214, so that the insulating impact rod 213 squeezes the piezoelectric ceramic component 217. The polarization direction of the grains of the piezoelectric ceramic component 217 changes, and the positive and negative charge centers no longer coincide. Equal amounts of bound charges with opposite signs will appear on the two surfaces perpendicular to the stress, thereby generating a voltage. By connecting to the circuit of the control motherboard 17, these charge movements will generate current, and the control motherboard 17 will amplify the current signal and pass it into the electromagnetic switch 218. At this time, the electromagnetic switch 218 will be powered on and closed. The second normally open solenoid valve 224 and the normally closed solenoid valve 223 are powered on, and the delayed power-off module of the control main board 17 causes the second normally open solenoid valve 224 and the normally closed solenoid valve 223 to be powered off for 1 second. At this time, the suction end of the air pump 121 will inhale the external air through the suction pipe 122 and the branch suction pipe 221, and the gas flow meter 222 will calculate the flow of the inhaled air. When the extrusion hemisphere 214 leaves a certain top pressure column 216, the piezoelectric ceramic component 217 rebounds and recovers under its own elastic recovery. When it moves to the next top pressure column 216, the piezoelectric ceramic component 217 is squeezed again to generate an electrical signal, and the electromagnetic switch 218 is closed again, so that the second normally open solenoid valve 224 and the normally closed solenoid valve 223 are powered on. The valve 223 continues to remain powered on until the annular movable base 2 stops moving. At this time, the piezoelectric ceramic component 217 has two states. One is that the squeezing hemisphere 214 is not in contact with the top pressure column 216, and the piezoelectric ceramic component 217 remains in a straight state. At this time, the charge of the piezoelectric ceramic component 217 is restored to be evenly distributed, so the piezoelectric ceramic component 217 does not generate an electrical signal. At this time, the moving contact of the electromagnetic switch 218 is disconnected, and the second normally open electromagnetic valve 224 and the normally closed electromagnetic valve 223 will also be powered off after a delay of 1 second. The second is that the squeezing hemisphere 214 is in contact with the top pressure column 216, and the piezoelectric ceramic component 217 remains in a deformed state. At this time, since the piezoelectric ceramic component 217 continues to maintain a deformed state, the charge inside the piezoelectric ceramic component 217 will be redistributed.Until the charge distribution is balanced, there will be no continuous charge flow, so the electrical signal of the piezoelectric ceramic component 217 will be disconnected, so the second normally open solenoid valve 224 and the normally closed solenoid valve 223 will also be powered off, that is, when the annular movable base 2 rotates and moves along the annular fixed base 1, the piezoelectric ceramic component 217 is continuously squeezed, so that the second normally open solenoid valve 224 and the normally closed solenoid valve 223 remain powered on, and when the annular movable base 2 stops rotating and moving, the second normally open solenoid valve 224 and the normally closed solenoid valve 223 remain powered off. This will cause the conductive head 67 and the electrode ring 66 to move relative to each other. Therefore, there will be a certain amount of wear between the conductive head 67 and the electrode ring 66. In order to ensure stable power supply, it is necessary to maintain the conductive head 67 and the electrode ring 66 (for example, replace the conductive head 67, etc.). When the conductive head 67 and the electrode ring 66 move relative to each other, air is taken in through the sub-suction pipe 221 and measured by the gas flow meter 222. The relative displacement distance between the conductive head 67 and the electrode ring 66 can be measured. When the gas flow meter 222 reaches the set flow rate (for example, the total amount of gas flowing through reaches 1m, 3 ), the gas flow meter 222 will output an electrical signal to the control main board 17, and the control main board 17 will issue an alarm prompt to the staff through its own alarm module (the alarm prompt method is different from the alarm method when the bellows 10 is damaged, such as an audible and visual alarm).
