Description

Technical Field

[0001] The present invention mainly relates to the technical field of battery production equipment, and in particular to a battery steel shell turning device. Background Art

[0002] Battery steel shell refers to the battery shell made of steel, which is usually used for some battery types that require higher durability and protection performance, such as lithium-ion batteries and nickel-metal hydride batteries. The steel shell has good strength and compression resistance, which can effectively protect the internal battery structure from external impact and damage. The battery steel shell is in a disordered state after electroplating. In order to make the disordered steel shell orderly and head-to-head consistent to enter the next process, specific sorting and turning equipment is required.

[0003] The existing technology discloses a battery steel shell U-turn mechanism, including a feed plate, a motor is provided on the front of the feed plate, a conveyor belt is provided on one side of the motor, a turntable is fixedly connected to the output end of the motor, a limit slot is provided in the middle of the top of the turntable, and two guide rails are symmetrically provided at the bottom of the turntable, a baffle is slidably connected to one side of the top of the two guide rails, and a bracket is fixedly installed on the other side of the top of the two guide rails. The present invention promotes the unloading of the battery steel shell through the operation of a hydraulic cylinder. When one end of the opening of the battery steel shell approaches the hydraulic cylinder, it can push the extrusion control switch, thereby triggering the motor to drive the turntable to rotate to 180 degrees, so that the closed end of the battery steel shell approaches the hydraulic cylinder, and the hydraulic cylinder is driven again to push the battery steel shell to move. At this time, the opening position of the battery steel shell is penetrated by the control switch, so that it does not contact the control switch, thereby pushing the baffle to move until the battery steel shell is driven to be unloaded and transported to the conveyor belt.

[0004] However, in the above technology, no matter the steel shell is in the correct direction or the wrong direction, it will enter the limit groove of the turntable along the feed plate, be contacted and pushed by the push block, and then wait for the subsequent motor to drive the turntable to rotate. There is a lack of a channel or avoidance mechanism that can directly release the steel shell in the correct direction, so that the steel shell in the correct direction is also trapped in the U-turn process, resulting in a waste of time and energy and slowing down the overall process efficiency; and the use of hydraulic cylinders to push the battery steel shell to be unloaded will affect the surface quality of the battery steel shell.

[0021] To facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive. Example

[0022] Please refer to the attached Figure 1 , 2 As shown in Figures 4 and 5, a battery steel shell turning device comprises a feeding mechanism 1, on which a diverter mechanism 2 is provided; the diverter mechanism 2 comprises a track diverter unit 5 and an airflow diverter unit 6, the track diverter unit 5 comprises a main track 501, the main track 501 is connected to the feeding mechanism 1, and a discharging track 502 is provided on the main track; the airflow diverter unit 6 comprises an airflow nozzle 601 and a discharging sub-track 602, the discharging sub-track 602 is arranged on one side of the main track 501, and the airflow nozzle 601 is arranged on the side of the main track 501 away from the discharging sub-track 602.

[0023] It should be noted that the track diversion unit 5 is asymmetrically inclined and is made of high-strength wear-resistant plastic material. It has certain flexibility and durability. The track diversion unit 5 uses the principle of gravity and the characteristic that the center of gravity of the battery steel shell is far away from the opening end, so that the steel shell with the correct opening direction will slide smoothly to the discharge track 502 by its own gravity in the inclined section. The whole process is smooth and rapid, effectively avoiding scratches and other damages on the surface of the battery steel shell; and the steel shell with the wrong opening direction, due to its different center of gravity distribution from the battery steel shell with the correct opening direction, will continue to move along the main track 501 and enter the subsequent airflow diversion unit 6.

[0024] It should be noted that the airflow nozzle 601 in the airflow diversion unit 6 is made of stainless steel, and its internal structure has been specially designed for aerodynamics, which can make the ejected airflow more concentrated and powerful. When the steel shell after the initial diversion by the track diversion unit 5 passes through the airflow nozzle 601, the opening faces the correct steel shell, and its bottom is flat and the complete arc surface faces the airflow ejected from the airflow nozzle 601, which can bear this thrust to the greatest extent. Under the push of the airflow, it enters the discharge sub-track 602, while the steel shell facing the wrong direction has its opening end aligned with the airflow nozzle 601, and the concave shape of the opening allows the airflow to be poured into it and dispersed, so the effective force actually acting on the steel shell to push its displacement is small, so that the battery steel shell continues to move along the main track 501.

[0025] It should be noted that the track diversion unit 5 preliminarily screens the opening directions of the steel shells, while the airflow diversion unit 6 further screens the steel shells screened by the track diversion unit 5, improves the diversion effect, and automatically separates and discharges the steel shells with the correct opening directions in advance. With the cooperation of the two, the steel shells with the correct opening directions can be avoided from entering the subsequent process, reducing unnecessary operations.

[0026] Please refer to the attached Figure 1 , 2 As shown in Figure 3, the feeding mechanism 1 includes a feeding plate 101, the feeding plate 101 is connected to a feeding conveyor belt 102, a material dividing unit 4 is arranged on the feeding conveyor belt 102, and the feeding conveyor belt 102 cooperates with the material dividing unit 4 to sequentially input the steel shells into the diversion mechanism 2. The material dividing unit 4 is symmetrically arranged on both sides of the feeding conveyor belt 102, including a material dividing cylinder 401, the material dividing cylinder 401 is connected to a connecting rod 402, and a material blocking rod 403 and a material clamping rod 404 are arranged at both ends of the connecting rod 402, the material blocking rod 403 and the material clamping rod 404 extend perpendicularly to the conveying direction of the feeding conveyor belt 102, and the ends of the material blocking rod 403 and the material clamping rod 404 are provided with a buffer pad 405.

[0027] It should be noted that the material distribution cylinder 401 drives the connecting rod 402 to move, thereby driving the blocking rod 403 and the clamping rod 404 to move synchronously. When the material distribution cylinder 401 is extended, the blocking rod 403 blocks all the steel shells arranged in sequence on the feeding conveyor 102. When feeding is required, the piston rod of the material distribution cylinder 401 contracts, driving the connecting rod 402 to move, so that the blocking rod 403 retracts and releases the first steel shell. At the same time, under the action of the connecting rod 402, the clamping rod 404 extends synchronously and clamps the next steel shell from the side. After the release of the first steel shell in front is completed, the material distribution cylinder 401 extends again, at this time, the blocking rod 403 extends, and the clamping rod 404 retracts synchronously, loosening the clamped second steel shell, so that it is blocked by the blocking rod 403. Repeat the above steps, so that the steel shells enter the subsequent process in a certain rhythm, to prevent the steel shells from getting stuck and piling up.

[0028] It should be noted that the distance between the blocking rod 403 and the clamping rod 404 and their respective lengths are adjusted according to the size of the steel shell. When the material distribution cylinder 401 extends, the blocking rod 403 blocks it in front of the steel shell. At this time, the clamping rod 404 is located near the middle of the second steel shell and keeps a certain distance from the side of the steel shell and cannot contact the steel shell. In addition, the buffer pad 405 set at the end of the blocking rod 403 and the clamping rod 404 is made of elastic rubber material, which can effectively avoid damaging the outer surface of the steel shell.

[0029] Please refer to the attached Figure 1 , 2 As shown in Figures 6 and 7, the main track 501 is connected to the adjustment mechanism 3, the adjustment mechanism 3 includes a vacuum adsorption unit 7, an air pressure pushing unit 8 and a control unit 9, the vacuum adsorption unit 7 is provided with a plurality of vacuum suction cups 701, the vacuum suction cups 701 are connected to a vacuum pipe 702, the other end of the vacuum pipe 702 is connected to a vacuum generator 703, the air pressure pushing unit 8 includes a pneumatic cylinder 801, the piston end of the pneumatic cylinder 801 is connected to a push plate 802, the contact surface of the push plate 802 and the steel shell is provided with a buffer layer 803, the control unit 9 includes a sensor module 901, the sensor module 901 integrates a visual sensor 9011 and a distance sensor 9012, and the sensor module 901 is electrically connected to a control main board 902, the control main board 902 is electrically connected to the vacuum adsorption unit 7 and the air pressure pushing unit 8.

[0030] It should be noted that when the steel shell with the wrong opening direction enters the adjustment mechanism 3 along the main track 501, the control unit 9 determines that the steel shell has reached the preset position through the visual sensor 9011, and then starts the vacuum adsorption unit 7. The vacuum suction cup 701 generates negative pressure under the action of the vacuum generator 703, closely fits the surface of the steel shell, and firmly adsorbs the steel shell. Then the control unit 9 starts the air pressure pushing unit 8 to start operation. The piston of the pneumatic cylinder 801 pushes the push plate 802 to contact the side of the steel shell, exerts an eccentric force to exert a torque around the rotation fulcrum determined by the vacuum suction cup 701, and drives the steel shell to rotate. During the rotation process, the control unit 9 continuously receives data feedback from the distance sensor 9012, dynamically adjusts the air pressure, and allows the steel shell to rotate smoothly. When the visual sensor 9011 and the distance sensor 9012 determine that the steel shell has rotated to the correct opening direction, the air pressure pushing unit 8 stops working, the vacuum adsorption unit 7 is closed, the negative pressure in the vacuum suction cup 701 disappears, the adsorption state of the steel shell is released, and the steel shell is discharged from the adjustment mechanism 3.

[0031] It should be noted that the vacuum suction cups 701 are arranged in a matrix on the main track 501, and the vacuum suction cups 701 are made of food-grade silicone material, which is soft and elastic, and has fine anti-skid patterns on its surface, which can ensure airtight fit and prevent scratches on the steel shell. The bottom of each vacuum suction cup 701 is connected to the vacuum generator 703 through a flexible polyvinyl chloride (PVC) short tube. The short tube is about 5-8 cm long and has a certain bending ability, so that the suction cup can adapt to the slight undulations on the surface of the steel shell; the vacuum generator 703 is a miniature vortex generator with a built-in high-precision impeller driven by a small brushless motor with a rotation speed of up to At 10,000-15,000 revolutions per minute, the air between the suction cup and the steel shell can be quickly extracted to form a stable negative pressure. The suction force ranges from 50 to 100 N, which is sufficient to firmly adsorb the steel shell. The vacuum pipe 702 is made of stainless steel with a pipe diameter of 8 to 12 mm and a wall thickness of 1 to 1.5 mm. It has good pressure resistance and air tightness. It is connected to the PVC short pipe at the bottom of each vacuum suction cup 701 through a three-way joint. A solenoid valve 7021 is provided on the vacuum pipe 702. The solenoid valve 7021 is electrically connected to the control unit 9, which is convenient for accurately controlling the adsorption and release of a single suction cup and realizing differentiated adsorption of different parts of the steel shell.

[0032] It should be noted that the pneumatic cylinder 801 is arranged on one side of the main track 501, with an inner diameter of 20-30 mm. Its piston is made of high-strength alloy steel, with hard chrome plating on the surface, smooth and wear-resistant, and a stroke of 5-10 cm, which is sufficient to meet the rotation amplitude required for the steel shell to adjust its direction; the push plate 802 is made of nylon, which is lightweight and smooth in surface, has a large contact area with the steel shell, and can evenly disperse the thrust.

[0033] It should be noted that the visual sensor 9011 uses a high-resolution camera, whose field of view covers the adjustment mechanism 3 area, and can accurately capture the position of the steel shell and the opening direction. The distance sensor 9012 is an infrared ranging sensor, which is arranged on one side of the main track 501. It monitors the distance between the steel shell and various components in real time, determines the angle of the steel shell, and provides data for the adjustment force.

[0034] The specific operation process of the present invention is as follows: First, the steel shells to be separated are transported to the feed conveyor belt 102 through the feed plate 101, and the dividing unit 4 on the feed conveyor belt 102 transports the steel shells to the diversion mechanism 2 in a certain rhythm and in an orderly manner; Then, the track diversion unit 5 in the diversion mechanism 2 preliminarily screens the orientation of the steel shells by the principle of gravity, and discharges the steel shells with the correct opening orientation from the discharging track 502, and the remaining steel shells enter the airflow diversion unit 6, and the airflow diversion unit 6 further screens the steel shells, and discharges the steel shells with the correct opening orientation that are not diverted by the track diversion unit 5 from the discharging auxiliary track 602, and the remaining steel shells with the wrong opening orientation are transported to the direction adjustment mechanism 3 along the main track 501; Finally, the vacuum adsorption unit 7 in the adjustment mechanism 3 firmly adsorbs the steel shell under the action of the control unit 9, cooperates with the eccentric force applied by the air pressure pushing unit 8, and completes the turning operation of the steel shell with the wrong opening direction under the real-time monitoring of the sensor module 901.

[0035] The above is an exemplary description of the present invention in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
