Description

Technical Field

[0001] The present invention relates to the technical field of logistics warehousing, and in particular to a heavy-load warehousing robot charging pile. Background Art

[0002] With the widespread application of factory automation, flexible manufacturing systems, and automated warehouses, stackers or AGVs, as necessary automated handling and loading and unloading means to connect and adjust logistics management systems to make their operations continuous, have seen rapid development in their application scope and technical level. Their charging technologies are mainly divided into full-cycle charging and random charging. Full-cycle charging means that the stacker or AGV exits service and enters the designated charging area, and can only be charged when the battery charge drops to the specified range. Random charging aims to charge at any time at each docking station without time limit, ensuring that the power lost by the stacker robot or AGV during work is replenished in a timely manner, achieving shallow charging and discharge of the battery, which will greatly extend the battery life.

[0003] However, the existing charging piles still need manual assistance to a certain extent, mainly because the charging docking is not accurate enough, and the contact conductive connection is not tight enough during high-current charging. In particular, the charging device with a handheld standard charging gun structure requires manual intervention to dock and charge normally. The degree of automation is low, resulting in low charging efficiency, which affects the normal and efficient operation of the entire logistics system. As proposed in Chinese patent CN202222081454.9, an automatic docking charging pile includes: a fixing mechanism; a charging output head for electrically connecting to a power source; a guide cover, which is movably arranged on the charging output head for front and back connection, and is used to match and dock with the charging cover of the device to be charged, so as to guide the charging output head to align with the charging input head of the device to be charged; and an automatic adjustment mechanism, which installs the charging output head and the guide cover on the fixing mechanism, and is used to automatically adjust the position and / or angle of the charging output head and the guide cover; wherein the automatic adjustment mechanism includes a first front and rear adjustment component and a second front and rear adjustment component that are independent of each other, and the first front and rear adjustment component is connected to the guide cover for adjusting the front and rear position of the guide cover; the second front and rear adjustment component is connected to the charging output head, and is used to adjust the front and rear position of the charging output head, so that the charging output head can electrically dock with the charging input head. However, the charging pile structure is not suitable for docking charging with a standard handheld charging gun, nor is it suitable for automatic docking for high-current charging; this also makes it impossible for existing large-battery heavy-load storage robots to use the above structure for fast and automatic charging.

[0014] (III) Beneficial effects: Compared with the prior art, the present invention provides a heavy-duty warehouse robot charging pile, which has the following beneficial effects:

[0015] 1. The heavy-duty warehouse robot charging pile, through the use of the lifting plate structure and the translation plate structure, can keep the charging pile floating in the left and right, up and down, front and back directions, and cooperate with the guiding function of the convex and concave joints to achieve automatic centering docking between the charging gun head and the charging lead. Combined with the left and right, up and down self-correction function of the buffer seat of the damping material, the charging gun head and the charging lead are more tightly connected, reducing the contact resistance and ensuring high current charging. This allows heavy-duty warehouse robots to use the above structure for fast and automatic charging.

[0016] 2. The heavy-duty warehouse robot charging pile, through the coordinated use of the convex joint structure and the concave joint structure, constrains the freedom of the charging gun head from the left and right, up and down, front and back directions, and stabilizes the handheld charging gun head on the left and right lifting plates. It has a simple structure and is easy to disassemble and assemble. And by using the height adjustment screws, translation adjustment nuts, up and down fine-tuning nuts, and combining with the indication of the spirit level, the height, left and right, and horizontal position adjustment of the charging gun head can be completed conveniently and quickly. At the same time, the contact blocking action of the guide rod limit plate on the installed docking guide rod and the limit switch connecting rod is utilized to accurately indicate whether the charging gun head and the charging lead are in contact and in place. It has a simple structure, reliable indication, and convenient adjustment and maintenance.

[0017] 3. The heavy-duty storage robot charging pile uses a buckle structure and a magnetic baffle structure in combination. The main fan blades are not only limited by the buckle in the circumferential direction and the axial direction, but also by the axial thrust of the magnetic baffle. Under this double limit, the male and female joints can be more stable after docking, thereby improving the safety of the charging process. The rotor of this structure will stop rotating only when the charging gun head stops supplying power. The bayonet is reset by the tension spring, and the magnetic baffle lifts the female joint so that the female joint can be separated from the male joint, thereby avoiding the danger of the female joint being detached during power supply. Moreover, when supplying power, the charging gun head will only supply power when the magnetic baffle is contracted and the buckle is extended, thereby greatly improving the safety of the equipment. The wind generated by the rotation of the main and auxiliary fan blades will pass through the annular heat sink and reduce its temperature, thereby avoiding overheating at the connection between the charging lead and the charging gun head.

[0018] 4. The heavy-load storage robot charging pile uses the rotor structure and the main fan blade structure in coordination. During the power supply process, the higher the power of the charging gun head, the higher the rotor speed, the stronger the heat dissipation capacity of the main fan blades and the auxiliary fan blades. By observing the rotation of the main fan blades with color spray paint at the transparent position on the surface of the concave joint, it can be judged whether the concave joint and the convex joint are in working condition, which greatly improves the work efficiency of the inspectors.

[0029] See also Figure 1-Figure 5A heavy-duty warehouse robot charging pile includes a base 1 and a clamping docking assembly 2. The clamping docking assembly 2 is arranged on the base 1, and a lifting plate 5 is fixedly installed at the bottom of the clamping docking assembly 2. The clamping docking assembly 2 is arranged on the base 1, and the height is adjusted by the lifting plate 5 to ensure the accuracy and stability of the docking. Lifting guide rods 51 are slidably installed at both ends of the lifting plate 5. A lifting spring 52 is arranged between the lifting guide rod 51 and the lifting plate 5. The lifting guide rod 51 is used to guide the vertical movement of the lifting plate 5 to ensure its stability and accuracy during the movement. The lifting spring 52 provides a certain buffering and reset capacity, so that the lifting plate 5 can move smoothly and return to the initial position when subjected to external force. A translation plate 6 is fixedly installed at the bottom of the lifting guide rod 51. The translation plate 6 is used to fine-tune the clamping docking assembly 2 in the horizontal direction to adapt to the deviation of the stacker or AGV vehicle in the horizontal direction. The linkage adjustment in the lifting and translation directions can be achieved by fixing the translation plate 6 at the bottom of the lifting guide rod 51. A translation guide rod 61 is fixedly installed at the bottom of the translation plate 6. The translation guide rod 61 is used to guide the horizontal movement of the translation plate 6 to ensure its stability and accuracy during the movement. Similar to the lifting guide rod 51, the translation guide rod 61 plays a guiding and supporting role. A fixed middle plate 7 is provided at the bottom of the translation plate 6.

By fixing the middle plate 7, the stability and reliability of the translation guide rod 61 during the movement can be ensured. A translation spring 62 is provided between the translation guide rod 61 and the fixed middle plate 7. The translation spring 62 provides a certain buffering and reset capacity, so that the translation plate 6 can move smoothly and return to the initial position when subjected to external force. This helps to maintain the stability and accuracy of the clamping docking assembly 2. The fixed middle plate 7 is fixedly connected to the base 1, and the fixed connection between the fixed middle plate 7 and the base 1 ensures the stability and reliability of the entire charging pile structure. This connection method can prevent the charging pile from shaking or deforming when subjected to external force; the clamping docking assembly 2 includes a male joint 21 and a female joint 22, which are key components for docking the charging pile with a stacker or AGV vehicle. Through the cooperation of the male joint 21 and the female joint 22, the automatic centering docking of the charging gun head 218 and the charging lead can be achieved, thereby ensuring the accuracy and stability of charging. A docking guide rod 31 is fixedly provided at the tail of the male joint 21, and the docking guide rod 31 is slidably connected with a clamping plate 3. The docking guide rod 31 is used to guide the docking process of the male joint 21 and the female joint 22, and ensure the accuracy and stability of the docking. The clamping plate 3 is used to clamp the male joint 21 during the docking process to prevent it from shaking or falling off.A docking guide spring 32 is provided between the clamping plate 3 and the docking guide rod 31. The docking guide spring 32 provides a certain buffering and resetting capability, so that the clamping plate 3 can move smoothly and return to the initial position when subjected to external force. This helps to maintain the stability and accuracy between the male connector 21 and the female connector 22. A limit switch striker 33 is also provided on the clamping plate 3, and the limit switch striker 33 is triggered after the docking guide rod 31 slides. The limit switch striker 33 is used to trigger the limit switch to indicate the docking state between the male connector 21 and the female connector 22. When the male connector 21 and the female connector 22 are successfully docked, the limit switch striker 33 will trigger the limit switch, thereby issuing a charging instruction.

[0030] See also Figure 1-Figure 5A charging seat mounting frame 4 is provided at the tail of the female connector 22, and a buffer seat 41 is also provided on the charging seat mounting frame 4. The charging seat mounting frame 4 is used to fix the charging seat to ensure that the charging seat and the male connector 21 can be accurately docked. The buffer seat 41 is used to provide a buffering effect during the docking process, reduce the impact and vibration during docking, and protect the charging lead and the male connector 21 from damage. The buffer seat 41 is made of damping material, which has the characteristics of shock absorption, vibration reduction and buffering, and can effectively reduce the impact and vibration during docking, and improve the stability and reliability of docking. The damping material is made of rubber, silicone, polyurethane, etc. These materials have excellent elasticity and damping properties, and can meet the buffering requirements when the charging pile is docked. A charging lead is provided inside the female connector 22, and a charging gun head 218 is provided inside the male connector 21. The charging lead and the charging gun head 218 are key components for the transmission of power between the charging pile and the stacker or AGV vehicle. The charging gun head 218 is responsible for transmitting electrical energy from the charging gun head 218 to the charging lead, while the charging lead is responsible for transmitting electrical energy to the battery of the stacker or AGV vehicle. Two or more docking guide rods 31 are provided. Two or more docking guide rods 31 can improve the accuracy and stability of docking. During the docking process, multiple guide rods can jointly guide the accurate docking of the male joint 21 and the female joint 22 to reduce deviations and errors. A level 34 is fixedly provided above the clamping plate 3. The level 34 is used to detect the horizontal state of the clamping plate 3 and the male joint 21 to ensure that the male joint 21 can remain horizontal during the docking process, thereby improving the accuracy and stability of docking. A guide rod limit plate is also provided at the tail of the docking guide rod 31. The guide rod limit plate is used to limit the stroke of the docking guide rod 31 to prevent it from excessive movement or falling off during the docking process. At the same time, the guide rod limit plate also serves as a striker to trigger the limit switch, which is used to indicate the completion status of the docking. A translation linear bearing 63 is arranged between the translation guide rod 61 and the translation plate 6. The translation linear bearing 63 can reduce the friction and wear between the translation guide rod 61 and the translation plate 6, and improve the smoothness and accuracy of the translation. At the same time, it can also withstand certain radial and axial loads to ensure the stability and reliability of the translation structure. A translation slider 64 is also fixedly arranged on the translation plate 6, and a translation rail 71 is fixedly arranged on the fixed middle plate 7. The translation slider 64 is fixedly installed on the translation rail 71. The cooperation of the translation slider 64 and the translation rail 71 can achieve the smooth movement and precise positioning of the translation plate 6. By adjusting the position of the slider on the rail, the moving distance of the translation plate 6 can be fine-tuned. A translation adjustment nut 65 is also arranged between the translation spring 62 and the fixed middle plate 7. The translation adjustment nut 65 is used to adjust the preload and stiffness of the translation spring 62, so as to achieve fine-tuning of the moving speed and position of the translation plate 6. By rotating the adjustment nut, the compression amount of the spring can be changed, thereby adjusting the movement characteristics of the translation plate 6. A height adjustment screw 72 is also provided between the fixed middle plate 7 and the base 1. The height adjustment screw 72 is used to adjust the overall height and horizontal state of the charging pile.By rotating the adjustment screw, the relative position between the fixed middle plate 7 and the base 1 can be changed, thereby achieving fine adjustment of the height of the charging pile. This helps to ensure the stability and accuracy of the charging pile under different ground conditions. A lifting guide sleeve 53 is provided between the lifting guide rod 51 and the lifting plate 5. The bottom of the lifting guide sleeve 53 is fixedly installed on the lifting plate 5. The lifting guide sleeve 53 is used to guide the vertical movement of the lifting guide rod 51 to ensure the stability and accuracy of the lifting plate 5 during the movement. At the same time, it can also reduce the friction and wear between the lifting guide rod 51 and the lifting plate 5. The lifting spring 52 is fixedly connected to the lifting guide sleeve 53, and the top of the lifting guide rod 51 is fixedly connected with a connecting rod 54. The connecting rod 54 fixes the lifting guide rods 51 at both ends. The connecting rod 54 is used to connect the lifting guide rods 51 at both ends to form a stable frame structure. By adjusting the position of the upper and lower fine-tuning nuts 55, the moving distance of the lifting guide rod 51 can be fine-tuned. This helps to ensure the accuracy and stability of the lifting plate 5 during the movement. A vertical fine-tuning nut 55 is provided between the link rod 54 and the lifting guide rod 51, and the vertical fine-tuning nut 55 is fixedly connected to the lifting spring 52. By fixedly connecting the vertical fine-tuning nut 55 and the lifting spring 52, the preload force of the lifting spring 52 can be fine-tuned. This helps to adjust the moving speed and position of the lifting plate 5, thereby meeting different docking requirements.

[0031] See also Figure 6-Figure 8, a stator 211 is coaxially fixedly installed on the male joint 21, and a rotor 212 is rotatably installed on the stator 211. The combination of the stator 211 and the rotor 212 constitutes the basic structure of the motor, which is used to provide power when the male joint 21 and the female joint 22 are docked. When the male joint 21 and the female joint 22 are docked and energized, the magnetic field generated by the stator 211 will drive the rotor 212 to rotate, thereby driving other related components to work. A buckle 213 that can slide along the radial direction of the shaft is provided in the rotor 212. The buckle 213 is designed to extend and snap into the slot 222 of the main blade 221 when the rotor 212 rotates, thereby driving the main blade 221 to rotate. The buckle 213 can slide along the radial direction of the shaft and can smoothly cooperate with the slot 222 when extending and retracting. An annular air inlet mesh plate 214 is also provided on the inner end surface of the female joint 22. The air inlet mesh plate 214 is used to guide air into the interior of the female joint 22, and provide the necessary airflow for the rotation of the main blades 221 and the auxiliary blades 223. At the same time, the air inlet mesh plate 214 can also prevent large particles of debris from entering the interior of the female joint 22, protecting the internal components from damage. An annular magnetic baffle plate 215 that can slide perpendicular to the inner end surface is also provided on the inner end surface of the female joint 22. The magnetic baffle plate 215 is designed to provide additional stability when the male joint 21 and the female joint 22 are docked. When the magnetic baffle plate 215 is pushed out, the buckle 213 is clamped to prevent it from sliding out. This is to ensure that the buckle 213 can only be ejected by centrifugal force when the magnetic baffle plate 215 is contracted, so as to prevent the buckle 213 from accidentally ejecting. A compression spring 216 and a distance sensor are provided between the magnetic baffle plate 215 and the male joint 21. The compression spring 216 is used to keep the magnetic baffle plate 215 in the pushed-out state when the male joint 21 is not inserted. The distance sensor is used to detect the proximity between the male connector 21 and the female connector 22. When the male connector 21 approaches the female connector 22, the sensor triggers the relevant action, starts the stator 211 to rotate, etc. When the compression spring 216 is not compressed, the magnetic baffle 215 is pushed out of the female connector 22. This is to ensure that when the male connector 21 is not inserted into the female connector 22, the magnetic baffle 215 can remain in the pushed-out state and limit the buckle 213 structure. A tension spring 217 and a distance sensor are connected between the buckle 213 and the rotor 212. When the tension spring 217 is not stretched, the buckle 213 is pulled back into the rotor 212. The tension spring 217 is used to pull the buckle 213 back into the rotor 212 when the rotor 212 stops rotating, so as to prevent the buckle 213 from extending out in a non-working state and causing interference. The distance sensor is used to detect the position of the buckle 213. When the buckle 213 is fully extended, the charging gun head 218 is started to charge, thereby improving the safety of the equipment. The convex joint 21 is rotatably connected to the annular main fan blade 221, and the main fan blade 221 is designed to generate airflow when the rotor 212 rotates, thereby providing the necessary wind force for the heat dissipation of the charging pile.The inner ring surface of the main blade 221 is provided with a slot 222 that matches the buckle 213. The slot 222 is designed to cooperate with the buckle 213. When the buckle 213 is extended, it can be inserted into the slot 222 and drive the main blade 221 to rotate. This design ensures that the main blade 221 can rotate stably under the drive of the rotor 212. And the auxiliary blade 223 is rotatably connected in the convex joint 21, and the auxiliary blade 223 is designed to further enhance the heat dissipation effect. An annular plate 224 is connected between the auxiliary blade 223 and the main blade 221, and the annular plate 224 is designed to connect the auxiliary blade 223 with the main blade 221 to form an integral structure. An annular heat sink 225 is rotatably connected between the auxiliary blade 223 and the main blade 221, and the annular heat sink 225 is designed to increase the heat dissipation area and improve the heat dissipation efficiency. By increasing the number and thickness of the heat sink, the temperature at the junction of the charging gun head 218 and the charging lead can be more effectively reduced. The annular heat sink 225 is fixedly connected to the male connector 21, and the fixed connection design ensures that the annular heat sink 225 can be stably fixed on the male connector 21 and will not be displaced during the heat dissipation process. A ring-shaped exhaust mesh plate 226 is provided on the end face of the male connector 21. The exhaust mesh plate 226 is designed to discharge the hot air generated by the heat dissipation system from the outside of the charging pile to prevent heat accumulation from causing the charging pile to overheat. At the same time, the exhaust mesh plate 226 can also prevent large particles of debris from entering the charging pile. When the male connector 21 is installed on the female connector 22, the male connector 21 pushes the magnetic baffle 215 in, and at the same time, the rotor 212 drives the stator 211 to rotate, and the buckle 213 slides out under the centrifugal force and is inserted into the slot 222 to drive the main blade 221 to rotate. The buckle 213 is provided in several groups along the circumferential direction of the rotor 212, and the slot 222 is provided in several groups along the circumferential direction of the main blade 221. The main blades 221 and the rotor 212 are funnel-shaped and match each other. The funnel shape allows the main blades 221 to be in closer contact with the rotor 212, and the inner ring surface of the annular heat sink 225 is close to the connection between the charging lead and the charging gun head 218. This design helps to dissipate the heat generated during the charging process in time to prevent heat accumulation from causing overheating and damage to the charging lead and the charging gun head 218. A bearing is provided between the annular heat sink 225 and the annular plate 224, a winding is provided in the stator 211, and a magnet is provided in the rotor 212. The surface of the main blades 221 is sprayed with color paint, and the position where the main blades 221 and the concave joint 22 are connected is made of transparent material. The design of color spray paint helps to observe the rotation of the main blades 221 and judge whether the charging pile is in working condition. The use of transparent materials makes observation more intuitive and clear.

[0032] Working principle: When the present invention is used, it is installed in a fixed position with expansion screws. When the stacker or AGV vehicle needs to be charged as required, it automatically walks to the charging docking position, and the concave joint 22 installed on the vehicle body moves closer to the convex joint 21. At this time, there will be a certain spatial deviation between the concave joint 22 and the convex joint 21, but the maximum deviation value will not exceed the docking range of the concave and convex joint 21. The deviation is determined by the size error and walking accuracy of the stacker or AGV vehicle, and the docking range is determined by the structural dimensions of the convex joint 21 and the concave joint 22. When the concave joint 22 is docked with the convex joint 21, the concave joint 22 is aligned with the convex joint 21 and the concave joint 22 pushes the convex joint 21 to shrink the docking guide rod 31. When the limit plate of the docking guide rod 31 touches the limit switch striker 33 and triggers the limit switch to move in place, it means that the charging gun head 218 has been inserted, and a charging instruction can be issued to the stacker or AGV. During the docking process, the position of the male connector 21 is adjusted by the lifting plate 5 and the translation plate 6 to reduce the error. The lifting plate 5 is moved vertically up and down by the lifting guide rod 51, and the translation plate 6 is moved horizontally left and right by the translation guide rod 61. The lifting guide rod 51 can be fine-tuned by the up and down fine-tuning nut 55, and the translation adjustment nut 65 can be fine-tuned by the translation guide rod 61. The moving distance, so that the charging pile can be kept floating in the left and right, up and down, front and back directions, cooperate with the guiding effect of the male connector 21 and the female connector 22, and realize the automatic centering docking of the charging gun head 218 and the charging lead. Combined with the left and right, up and down self-correction effect of the buffer seat 41 of the damping material, the charging gun head 218 is more tightly connected with the charging lead, reducing the contact resistance and ensuring high current charging. When charging is completed, the vehicle body is instructed to retreat. When the male and female connectors 22 are completely disengaged, the limit switch returns to the original position, and the translation plate 6 and the lifting plate 5 return to the initial position due to the spring action. The male connector 21 is also smoothly extended due to the action of the docking guide translation spring 62 and the lifting spring 52, and its front end surface is higher than the charging gun head 218, ensuring that the gun head is not exposed. The charging pile returns to the waiting state to prepare for the next cycle of charging.

[0033] When the female joint 22 is fixedly docked with the male joint 21, the end face of the female joint 22 first contacts the end face of the male joint 21 and squeezes the magnetic baffle 215 to shrink, which is sensed by the distance sensor. At this time, the stator 211 starts to make the rotor 212 start to rotate. During the rotation, the buckle 213 is affected by the centrifugal force and extends from the rotor 212 and is inserted into the slot 222, thereby driving the main blade 221 and the auxiliary blade 223 to rotate. At this time, the main blade 221 is not only limited by the buckle 213 in the circumferential direction and the axial direction, but also by the axial thrust of the magnetic baffle 215. Under this double limit, the male joint 21 and the female joint 22 can be docked more stably. When the buckle 213 is extended, it will be sensed by the internal distance sensor, and the male joint 21 and the female joint 22 are docked. When the female joint 22 is separated from the male joint 21, the above steps are opposite. The wind generated by the rotation of the main blades 221 and the auxiliary blades 223 will pass through the annular heat sink 225 and reduce its temperature, thereby preventing overheating at the connection between the charging lead and the charging gun head 218. When the charging gun head 218 stops supplying power, the rotor 212 stops rotating, and the bayonet is reset by the tension of the tension spring 217, and the magnetic baffle 215 lifts the female connector 22 to disengage it. This structure ensures that the female connector 22 can only be separated from the male connector 21 when the charging gun head 218 stops supplying power, avoiding the danger of the female connector 22 being separated when supplying power, and the charging gun head 218 will only supply power after the magnetic baffle 215 shrinks and the buckle 213 extends, greatly improving the safety of the device.

[0034] During the power supply process, the higher the power of the charging gun head 218, the higher the speed of its rotor 212, and by observing the rotation of the main fan blades 221 with color spray paint at the transparent position on the surface of the female connector 22, it can be determined whether the female connector 22 and the male connector 21 are in a working state, which greatly improves the work efficiency of the inspectors.
