Description

Technical Field

[0001] This application relates to the technical field of automated warehousing equipment, and particularly to an automatic calibration lifting stacker for lithium battery transfer baskets. Background Art

[0002] With the rapid development of the new energy vehicle industry, the demand for lithium batteries has increased significantly, posing higher requirements for the production and storage of lithium batteries. Traditional lithium battery warehousing systems rely mostly on manual operations, which are not only inefficient but also error-prone. In recent years, automated warehousing equipment has gradually become popular. By introducing various sensors and control systems, the intelligence level of the warehousing system has been improved, significantly enhancing warehousing efficiency and safety. However, despite the increased automation, there are still many challenges in actual operation, especially in high-precision positioning and anti-collision. Existing technical means cannot fully meet the requirements; After retrieval, common solutions in the prior art include, but are not limited to: photoelectric sensor detection method, mechanical guiding device, and vision detection system, etc. These methods have their own advantages and disadvantages, but the common problem is that they cannot achieve efficient and accurate automatic calibration and adjustment. Especially in a complex and changeable industrial environment, it is difficult to achieve ideal results. The inventor found the following problems in the prior art during the implementation of this application: After lithium batteries are produced, they are placed in rows in transfer baskets and circulated on the automatic production line. During the movement of the transfer basket along the conveyor belt, vibrations or knocks are inevitable, which can easily cause the angle of the transfer basket to shift and skew. When the lifting stacker transfers the transfer basket to the storage warehouse, it may not be able to enter the warehouse because the transfer basket is skewed. Similarly, when the size of the transfer basket is inappropriate, it will also occur that it cannot enter the warehouse, causing the transfer basket to hit the storage warehouse opening, resulting in damage to the storage warehouse or the transfer basket. Seriously, it may cause the battery to fall due to the impact and catch fire. At the same time, when the steel wire of the lifting drive mechanism breaks due to long-term wear and tear of the device during operation, the transfer warehouse will slide down rapidly, and the device usually does not have a buffer mechanism to buffer its stall process. Summary of the Invention

[0003] The purpose of this application is to provide an automatic calibration lifting stacker for lithium battery transfer baskets.

[0004] In the first aspect, an automatic calibration lifting stacker for lithium battery transfer baskets provided by this application adopts the following technical solution: An automatic calibration lifting stacker for a lithium battery transfer basket, comprising a guide rail, a lifting frame is arranged on one side of the top of the guide rail, a driving mechanism is arranged at the bottom end of the lifting frame, the driving mechanism includes a driving motor, a reducer and a driving wheel, the driving motor is arranged on one side of the bottom of the lifting frame, the driving wheels are arranged in a row at the bottom end of the lifting frame, the output end of the driving motor is connected to the driving shaft of the driving wheel through the reducer, a top rail is arranged above the lifting frame, a slider is connected to the outer wall of the top of the lifting frame, the slider is sleeved on the outer wall of the top rail, a transfer bin is arranged inside the lifting frame, the transfer bin is connected to the lifting frame through a lifting driving mechanism, high-definition cameras are arranged on both sides of the top of the transfer bin, an AI chip is arranged on one side of the high-definition camera, a controller is arranged on one side of the transfer bin, and an alarm is arranged on the top of the controller.

[0005] By adopting the above technical scheme, the lifting frame can translate along the guide rail, and the lifting frame plays a supporting role. The output end of the driving motor drives the driving wheel to rotate after being decelerated by the reducer, thereby driving the lifting frame to translate, so as to facilitate the transfer of goods at different positions. At the same time, the lifting drive mechanism can drive the transfer warehouse to perform lifting movement, thereby realizing the transfer of goods in warehouses of different heights. Among them, the lifting drive mechanism includes a motor, a reducer, a winding drum, a steel rope and other structures to lift the transfer warehouse. The lifting drive mechanism is a prior art and is commonly used in this field, so it will not be explained in detail here. When the transfer basket approaches the transfer warehouse, the high-definition camera takes the first photo, and the AI ​​chip analyzes the photo to determine whether the size of the transfer basket is appropriate. If the size is appropriate, the transfer basket continues to move forward and enter the transfer warehouse. If the transfer basket is too large, the AI ​​chip transmits a signal to the controller, and the controller controls the alarm to sound an alarm to remind the staff to handle it. The transfer basket of the right size continues to move forward and enter the transfer warehouse. The size of the transport basket is detected in real time, which effectively prevents oversized or undersized transfer baskets from entering the storage warehouse, reduces the risk of equipment damage, and ensures the safe operation of the production line. The high-definition camera takes a second photo again, and the AI ​​chip analyzes the photo to determine whether the position of the transfer basket is correct. If the transfer basket is skewed, the AI ​​chip calculates the skew angle and controls the transmission mechanism through the controller to adjust the movement speed of the two conveyor belts to restore the transfer basket to the correct posture. After the transfer basket is straightened, it continues to move forward and enters the storage warehouse through the exit, realizing automatic calibration of the transfer basket, ensuring that the transfer basket is always in the correct posture before entering the storage warehouse, greatly reducing the problem of being unable to enter the warehouse due to the skew of the transfer basket, improving the automation level of the warehousing system, reducing manual intervention, and improving work efficiency and production safety. It is particularly suitable for automated warehouse systems for large-scale lithium battery production and storage. Among them, the AI ​​chip can select different embedded AI processors according to actual needs, such as the NVIDIA Jetson series or the Intel Movidius series. The high-definition camera is specifically a high-resolution industrial camera to ensure image clarity. The controller uses a PLC or a microcontroller to achieve coordinated control of the motor and the camera.

[0006] A strip limiting path is provided at the edge of the lifting frame, a fixed frame is arranged and connected at the edge of the transfer bin, an end of the fixed frame away from the transfer bin is connected to a rubber roller through a rotating shaft, the rubber roller abuts against the outer wall of the strip limiting path, a feed port is provided on one side of the transfer bin, and a discharge port is provided on the side of the transfer bin away from the feed port.

[0007] By adopting the above technical solution, the strip limit track plays a limiting role, and the transfer bin drives the fixed frame to rise and fall synchronously during the lifting process, so that the rubber roller rolls in the strip limit track, thereby improving the stability of the lifting of the transfer bin.

[0008] A dividing strip is provided at the center of the inner wall at the bottom end of the transfer bin, and conveying mechanisms are provided on both sides of the dividing strip, and the conveying mechanisms include transmission rollers, conveyor belts and servo motors. Transmission rollers are connected to both sides of the dividing strip through bearings, and the end of the transmission roller away from the dividing strip is connected to the inner wall of the transfer bin through bearings. Conveyor belts are sleeved on the outer walls of the two groups of transmission rollers, and servo motors are provided on the outer walls of both sides of the transfer bin. The output ends of the two groups of servo motors are connected to the transmission rollers at corresponding positions, and the transmission rollers are driven to rotate by the servo motors, and the rotation of the transmission rollers drives the conveyor belts to rotate.

[0009] By adopting the above technical solution, the dividing bar plays a separating role, and the two sets of conveying mechanisms are independently controlled by the controller. The servo motor drives the transmission roller to rotate, and the rotation of the transmission roller drives the conveyor belt to rotate to transmit the transfer basket. When the transfer basket is skewed, the AI ​​chip calculates the skew angle, and controls the conveying mechanism through the controller to adjust the movement speed of the two conveyor belts, so that the transfer basket returns to the correct posture and the transfer basket is straightened.

[0010] A movable cavity is provided in the middle of the fixed frame, and a braking mechanism is provided inside the movable cavity. The braking mechanism includes a movable block, a spring, a rubber abutment block and an extrusion groove. The side of the movable block close to the rubber roller is connected to the spring, and the end of the spring away from the movable block is connected to the rubber abutment block. The end of the rubber abutment block away from the spring abuts against the rubber roller, and an extrusion groove is formed between the rubber roller and an inner wall of one side of the fixed frame.

[0011] By adopting the above technical scheme, the elastic force of the spring makes the rubber block always contact with the rubber roller. When the transfer bin is lifted or lowered at a normal speed, the friction between the rubber roller and the rubber block drives the rubber block to tilt in the rolling direction when the rubber roller rotates, and the tension of the spring prevents the rubber block from sliding into the extrusion groove. When the device is worn out after a long period of work and the steel wire of the lifting drive mechanism breaks, the transfer bin will slide downward at a very fast speed, thereby driving the rubber roller to rotate at a high speed. The rapid rotation of the rubber roller drives the rubber block to move toward the edge, so that the rubber block moves into the extrusion groove. After the rubber block enters the extrusion groove, the rubber roller is braked to make it difficult to roll. The friction between the rubber roller and the strip limit track acts as a resistance to the descending transfer bin, thereby achieving a certain degree of buffering, thereby preventing the transfer bin from falling quickly in the case of a stall, thereby damaging the battery inside the transfer basket.

[0012] On one side of the braking mechanism, an adjusting mechanism is provided. The adjusting mechanism includes a threaded cylinder, a screw rod, an adjusting knob, a limiting groove and a guide rod. The threaded cylinder is connected to the fixed frame through a bearing. One side inner wall of the threaded cylinder is threadedly connected with the screw rod. The end of the screw rod away from the threaded cylinder is connected to the movable block.

[0013] By adopting the above technical solution, the position of the movable block can be adjusted through the adjusting mechanism, so as to adjust the tightness of the spring, and prevent the rubber abutting block from entering the extrusion groove at normal speed.

[0014] On one side inner wall of the fixed frame, limiting grooves are arranged in sequence. On both sides of the screw rod, guide rods are provided. The guide rods are connected to the movable block. The ends of the guide rods away from the movable block are embedded in the limiting grooves. On one side outer wall of the fixed frame, an adjusting knob is provided. The output end of the adjusting knob is connected to the threaded cylinder. Turning the adjusting knob can drive the threaded cylinder to rotate. The rotation of the threaded cylinder drives the screw rod to perform a translational motion. The movement of the screw rod drives the movable block to perform a synchronous translational motion.

[0015] By adopting the above technical solution, a tool such as a wrench is inserted into the cavity between the fixed frame and the transfer bin to twist and adjust the adjusting knob. The twisting of the adjusting knob drives the threaded cylinder to rotate. The rotation of the threaded cylinder drives the screw rod to perform a translational motion. The movement of the screw rod drives the movable block to perform a synchronous translational motion, so as to adjust the tightness of the spring and prevent the rubber abutting block from entering the extrusion groove at normal speed.

[0016] On both sides inner walls of the transfer bin, lead screws are connected through bearings. The outer walls of the lead screws are threadedly connected with lifting blocks. On the sides of the lifting blocks away from the inner walls of the transfer bin, protection frames are provided. On one side of the lead screw, a limiting rod is provided. The limiting rod penetrates through the middle of the lifting block.

[0017] By adopting the above technical solution, the rotation of the lead screw drives the lifting block to perform a lifting and translational motion. The movement of the lifting block drives the protection frame to perform a lifting motion. The protection frame moves to the middle of the transfer bin to play a role in limiting and protecting the transfer basket inside the transfer bin, and prevent the transfer basket from slipping during the movement of the transfer bin.

[0018] On the bottom outer wall of the transfer bin, second servo motors are arranged in sequence. The output ends of the second servo motors are connected to the lead screws. The second servo motors drive the lead screws to rotate. The rotation of the lead screws drives the lifting blocks to perform a lifting and translational motion. The movement of the lifting blocks drives the protection frames to perform a lifting motion.

[0019] By adopting the above technical solution, the No. 2 servo motor plays a driving role, so as to drive the protection frame to rise and fall so as to protect the transfer basket. The No. 2 servo motor drives the lead screw to rotate, and the rotation of the lead screw drives the lifting block to perform lifting and translational movements. The movement of the lifting block drives the protection frame to rise and fall, thereby performing a limiting protection function on the transfer basket inside the transfer warehouse.

[0020] The four ends of the bottom of the transfer bin are connected with brackets, the bottom end of the lifting frame is provided with a rubber pad, and the inner wall of one side of the transfer bin is provided with a temperature sensor, and the temperature sensor is connected to the controller through an electric wire.

[0021] By adopting the above technical solution, when the transfer bin is transferred to the bottom of the lifting frame, the bracket plays a supporting role, and the rubber pad plays a certain buffering role. The model of the temperature sensor is MLX90614. The temperature sensor can monitor the temperature of the lithium battery inside the transfer basket during the transfer process in real time. When the abnormal temperature of the lithium battery is detected, the signal is transmitted to the controller. The controller controls the alarm to sound an alarm to remind the staff to deal with it in time to avoid abnormalities of the lithium battery during the transfer process without being detected.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. When the transfer basket approaches the transfer warehouse, the high-definition camera takes the first photo, and the AI ​​chip analyzes the photo to determine whether the size of the transfer basket is appropriate. If the size is appropriate, the transfer basket continues to move forward and enters the transfer warehouse. If the transfer basket is too large, the AI ​​chip transmits the signal to the controller, and the controller controls the alarm to sound an alarm to remind the staff to handle it. The transfer basket of the right size continues to move forward and enters the transfer warehouse. The AI ​​chip detects the size of the transfer basket in real time, effectively avoiding transfer baskets that are too large or too small from entering the storage warehouse, reducing the risk of equipment damage and ensuring the safe operation of the production line. The high-definition camera takes the second photo again, and the AI ​​chip The photo is analyzed to determine whether the position of the transfer basket is correct. If the transfer basket is skewed, the AI ​​chip calculates the skew angle and controls the conveying mechanism through the controller to adjust the movement speed of the two conveyor belts to restore the transfer basket to the correct posture. After the transfer basket is straightened, it continues to move forward and enters the storage warehouse through the exit, realizing automatic calibration of the transfer basket, ensuring that the transfer basket is always in the correct posture before entering the storage warehouse, greatly reducing the problem of being unable to enter the warehouse due to the skew of the transfer basket, improving the automation level of the warehousing system, reducing manual intervention, and improving work efficiency and production safety. It is particularly suitable for automated warehouse systems for large-scale lithium battery production and storage; 2. The elastic force of the spring keeps the rubber abutting block always in contact with the rubber roller. When the transfer bin ascends and descends at a normal speed, as the rubber roller rotates, the frictional force between it and the rubber abutting block drives the rubber abutting block to tilt in the rolling direction. The tensile force of the spring prevents the rubber abutting block from sliding into the extrusion groove. When the device is worn out after long-term operation and the steel wire of the lifting drive mechanism breaks, the transfer bin will slide down rapidly, driving the rubber roller to rotate at a high speed. The rapid rotation of the rubber roller drives the rubber abutting block to move towards the edge, causing the rubber abutting block to move into the extrusion groove. After the rubber abutting block enters the extrusion groove, it realizes the braking effect on the rubber roller, making it difficult to roll. The frictional force between the rubber roller and the strip-shaped limiting track provides resistance to the descending transfer bin, achieving a certain degree of buffering and preventing the transfer bin from falling rapidly under the condition of stall, thus avoiding damage to the battery inside the transfer basket.

The model of the temperature sensor 44 is MLX90614. The temperature of the lithium battery inside the transfer basket during the transfer process can be monitored in real time through the temperature sensor 44. When the temperature of the lithium battery is detected to be abnormal, a signal is transmitted to the controller 13, and the controller 13 controls the alarm 14 to give an alarm to remind the staff to handle it in time, so as to avoid the lithium battery from occurring abnormally during the transfer process without being noticed.

[0034] The implementation principle of the embodiment of this application is as follows: First, the transfer basket filled with lithium batteries is transported to the transfer warehouse 9 through the conveyor belt. The lifting frame 2 can move horizontally along the guide rail 1. The output end of the driving motor 4 drives the driving wheel 6 to rotate through the reducer 5, thereby driving the lifting frame 2 to move horizontally, facilitating the transfer of different positions. At the same time, the lifting drive mechanism 10 can drive the transfer warehouse 9 to move up and down, thereby realizing the transfer of different height warehouses. When the transfer basket approaches the transfer warehouse, the high-definition camera 11 takes the first photo, and the AI chip 12 analyzes the photo to determine whether the size of the transfer basket is appropriate. If the size is appropriate, the transfer basket continues to move forward and enters the transfer warehouse. If the transfer basket is too large, the AI chip 12 transmits a signal to the controller 13, and the controller 13 controls the alarm 14 to issue an alarm to remind the staff to handle it. The transfer basket with appropriate size continues to move forward and enters the transfer warehouse 9. By using the AI chip 12 to detect the size of the transfer basket in real time, it effectively avoids the entry of too large or too small transfer baskets into the storage warehouse, reduces the risk of equipment damage, and ensures the safe operation of the production line. The high-definition camera 11 takes the second photo again, and the AI chip 12 analyzes the photo to determine whether the position of the transfer basket is correct. If the transfer basket is skewed, the AI chip 12 calculates the skewing angle and controls the conveyor mechanism 21 through the controller 13 to adjust the moving speeds of the two conveyor belts 23 to make the transfer basket return to the correct posture. After the transfer basket is straightened, it continues to move forward and enters the storage warehouse through the exit, realizing the automatic calibration of the transfer basket, ensuring that the transfer basket is always in the correct posture before entering the storage warehouse, greatly reducing the problem of inability to enter the warehouse caused by the skewing of the transfer basket, improving the automation level of the warehousing system, reducing manual intervention, enhancing work efficiency and production safety, and is particularly suitable for the automated warehouse system for large-scale lithium battery production and storage. The strip-shaped limiting track 15 plays a limiting role. During the lifting process of the transfer warehouse 9, the fixed frame 16 is driven to lift synchronously, so that the rubber rollers 17 roll in the strip-shaped limiting track 15, thereby improving the smoothness of the lifting of the transfer warehouse 9. The partition strip 20 plays a partitioning role. The two conveyor mechanisms 21 are independently controlled by the controller 13. The servo motor 24 drives the driving roller 22 to rotate, and the rotation of the driving roller 22 drives the conveyor belt 23 to rotate to drive the transfer basket. When the transfer basket is skewed, the AI chip 12 calculates the skewing angle and controls the conveyor mechanism 21 through the controller 13 to adjust the moving speeds of the two conveyor belts 23 to make the transfer basket return to the correct posture. After the transfer basket is straightened, the rubber abutting block 29 is always abutted against the rubber roller 17 by the elastic force of the spring 28. When the transfer warehouse 9 rises and falls at a normal speed, the rubber roller 17 drives the rubber abutting block 29 to tilt in the rolling direction due to the friction between the rubber roller 17 and the rubber abutting block 29, and the spring 28 prevents the rubber abutting block 29 from sliding into the extrusion groove 30. When the steel wire of the lifting drive mechanism 10 breaks due to long-term wear during the operation of the device, the transfer warehouse 9 will slide down rapidly.Thereby driving the rubber roller 17 to rotate at high speed, the rapid rotation of the rubber roller 17 drives the rubber abutting block 29 to move towards the edge, causing the rubber abutting block 29 to move into the extrusion groove 30. After the rubber abutting block 29 enters the extrusion groove 30, the braking effect on the rubber roller 17 is achieved, making it difficult to roll. The frictional force between the rubber roller 17 and the strip-shaped limiting track 15 provides resistance to the descending transfer bin 9 to achieve a certain degree of buffering, preventing the transfer bin 9 from falling rapidly in the case of stall and damaging the battery inside the transfer basket. When adjustment is required, a tool such as a wrench is inserted into the cavity between the fixed frame 16 and the transfer bin 9 to twist and adjust the adjustment knob 34. The twisting of the adjustment knob 34 drives the threaded cylinder 32 to rotate. The rotation of the threaded cylinder 32 drives the screw rod 33 to perform a translational movement. The movement of the screw rod 33 drives the movable block 27 to perform a synchronous translational movement to adjust the tightness of the spring 28, preventing the rubber abutting block 29 from entering the extrusion groove 30 at normal speed. The second servo motor 41 plays a driving role to drive the protection frame 39 to lift and lower to protect the transfer basket. The second servo motor 41 drives the lead screw 37 to rotate. The rotation of the lead screw 37 drives the lifting block 38 to perform a lifting and translational movement. The movement of the lifting block 38 drives the protection frame 39 to perform a lifting movement, thereby playing a limiting and protecting role for the transfer basket inside the transfer bin 9. When the transfer bin 9 is transported to the bottom end of the lifting frame 2, the support 42 plays a supporting role, and at the same time, the rubber pad 43 plays a certain buffering role. The model of the temperature sensor 44 is MLX90614. The temperature sensor 44 can monitor the temperature of the lithium battery inside the transfer basket in real time during the transfer process. When the abnormal temperature of the lithium battery is detected, a signal is transmitted to the controller 13, and the controller 13 controls the alarm 14 to issue an alarm to remind the staff to handle it in time, preventing the lithium battery from occurring abnormally during the transfer process without being noticed.,
