Description

TECHNICAL FIELD

[0001] The application relates to the technical field of battery production equipment, in particular to a lithium ion battery sorting and tray loading line. BACKGROUND

[0002] Lithium ion batteries are rechargeable secondary batteries with lithium ions as the core conductive carrier. With the advantages of high energy density, long cycle life and low self-discharge rate, they are widely used in consumer electronics, electric vehicles, energy storage systems, unmanned aerial vehicles, medical devices and other fields. They realize charging and discharging through the reciprocal migration of lithium ions between the positive and negative electrodes (the positive electrode commonly uses lithium cobaltate, lithium iron phosphate, etc., and the negative electrode is mostly graphite). The core components also include electrolyte, separator and shell, and need to be matched with a battery management system (BMS) to monitor charging and discharging and temperature to avoid safety risks.

[0003] Patent No. CN111282844B discloses a battery sorting equipment, which comprises a base, a motor box is fixedly installed on one side of the top surface of the base, a workbench is fixedly installed at the top end of the motor box, a first drive shaft is movably connected on one side of the workbench, a feeding box is fixedly installed on one side of the top of the workbench, a sorting turntable is movably installed between the first drive shaft and the feeding box on the top of the workbench, the sorting turntable comprises a turntable, a second drive shaft is fixedly installed on the top of the turntable, limit movable grooves are uniformly formed in the bottom of the turntable, battery containing columns are uniformly fixedly installed on the outer circle of the turntable, telescopic rods are fixedly installed on the bottom of the battery containing column and the connecting rod of the turntable, and a weighing and sorting block is movably connected on the bottom of the telescopic rod.

[0004] However, the track switching of the shunting device has mechanical delay when the existing device is used. In high-speed production scenarios, the track motion is often out of sync with the battery conveying rhythm, resulting in lagging sorting rhythm, which is difficult to match the mass production demand. In addition, the quality of the sorted and loaded tray is poor, and the battery placement state is chaotic. Not only is there a position offset, but also frequent stacking and tilting phenomena occur. This disordered state directly interferes with the automatic connection of the subsequent assembly process, greatly reducing the overall smoothness of the production line.

[0005] Therefore, in order to solve such problems, we propose a lithium ion battery sorting and tray loading line. SUMMARY

[0006] The purpose of this invention is to provide a lithium-ion battery sorting and traying line to solve the problem mentioned in the background art. When using the existing device, there is a mechanical delay in the track switching of the shunting device. In high-speed production scenarios, the track movement and the battery conveying rhythm are often out of sync, resulting in a lag in the sorting cycle, making it difficult to match mass production requirements. Furthermore, the traying quality after sorting is poor, and the battery placement is chaotic. Not only is there positional deviation, but there are also frequent stacking tilts. This disordered state directly interferes with the automated connection of subsequent assembly processes, significantly reducing the overall smoothness of the production line.

[0009] Furthermore, a battery identification component is fixedly connected to the right side of the top fixing plate of the base, and a conveying assembly is installed on the top baffle of the base.

[0010] Furthermore, both ends of the left side of the top baffle of the base are fixedly connected to fasteners, and rotating rods are rotatably connected above and below the fasteners on the top of the base. A servo motor is fixedly connected to the front end of the rotating rod below the fastener, and a rotating roller is fixedly connected to the outer end of the rotating rod. A conveyor belt is fixedly connected to the outer wall of the rotating roller.

[0011] Furthermore, placement plates are uniformly fixedly connected to the outer wall of the conveyor belt, a first partition is fixedly connected to the middle of the placement plate, and side plates are fixedly connected to both ends of the placement plate.

[0012] Furthermore, a collection box is fixedly connected to the inner side of the top baffle of the base, and an inclined plate is fixedly connected inside the collection box, with the inclined surface of the inclined plate facing to the right.

[0013] Furthermore, a second partition is fixedly connected inside the collection box, and door panels are movably connected to both ends of the right side of the collection box, with handles fixedly connected to the outer wall of the door panels.

[0015] (1) The lithium ion battery sorting and tray loading line can quickly adjust the angle of the limiting plate through the linkage structure composed of the air cylinder driven push rod, the movable bolt and the connecting plate, so that the real-time switching of the battery conveying direction is realized, the mechanical response time of the traditional shunting device is shortened, the battery conveying rhythm can be accurately matched in the high-speed production scene, the track action and the battery conveying are synchronized, the problem of sorting rhythm lag is avoided, the quantity production demand can be fully met, and meanwhile, the spring on the limiting plate and the protection plate form a buffer structure, when the battery contacts the limiting plate in the shunting process, the impact force can be absorbed through the elastic deformation of the spring, physical protection is formed with the help of the protection plate, the damage of the battery caused by the collision is reduced, and then the product qualification rate is improved.

[0016] (2) The first partition plate and the two side plates on the placement plate form a three-dimensional limiting structure, the battery can be bidirectionally constrained from the horizontal direction and the vertical direction, the position deviation of the battery caused by factors such as vibration and turning in the conveying belt conveying process is effectively avoided, and the stable posture of the battery in the transfer process is ensured.

[0017] Further, the inclined plate in the collection box guides the battery to smoothly slide along the inclined surface at an inclined angle, avoids the knocking or accumulation caused by the direct falling of the battery, ensures that the battery can enter the designated area in the box in an orderly manner, and cooperates with the door plate design on the right side which can be flexibly opened and closed through the handle, so as to provide a convenient operation space for the classification and collection of different types of batteries, and also enables the operator to take the battery without additional disassembly of components, and only needs to open the door plate to quickly complete the taking and placing, which significantly improves the operation convenience and efficiency in the production process.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0026] Embodiment one: a lithium ion battery sorting and loading line, through the synergistic effect of push rod 13, movable bolt 131, connecting plate 141 and limiting plate 15 and other components, the angle of limiting plate 15 is adjusted, and then the direction of battery conveying at the top of conveying assembly 121 is controlled, preventing mechanical delay in track switching of shunt device, in high-speed production scenarios, the track action is often out of sync with the rhythm of battery conveying, leading to sorting rhythm lag, difficult to match the production demand and other problems.

[0027] As Figure 1 - Figure 4As shown, a lithium ion battery sorting tray line includes a base 1, which is the basic support structure of the entire device, provides a mounting platform for each component, and ensures the stability of the device during operation. The front and rear of the top of the base 1 are fixedly connected with baffles 11, which play a lateral limiting role on the batteries on the conveying assembly 121, preventing the batteries from deviating from the track during conveying. The top of the rear baffle 11 of the top of the base 1 is fixedly connected with a T-shaped block, which provides mounting and movable support points for the air cylinder, allowing the air cylinder to perform stable extension and retraction actions. The T-shaped block is movably connected with an air cylinder, which is the power source for the entire sorting action and is started immediately according to the identification result of the battery identification piece 12 to output power to drive the push rod 13 to complete the extension and retraction action. The output end of the air cylinder is fixedly connected with the push rod 13, which transmits the power of the air cylinder to the movable bolt 131, which is driven to slide in the movable slot of the connecting plate 141 through the extension of the push rod 13. The end of the push rod 13 is fixedly connected with the movable bolt 131, which slides accurately in the movable slot of the connecting plate 141. Through cooperation with the movable slot, the linear motion of the push rod 13 is converted into the rotary motion of the connecting plate 141. The top of the front baffle 11 of the top of the base 1 is fixedly connected with a fixed plate 14, which provides rotary support for the rotating shaft to ensure that the rotating shaft can rotate stably around its axis. The fixed plate 14 is rotatably connected with a rotating shaft, which is rotated under the drive of the connecting plate 141 and then transmits the rotary motion to the limiting plate 15 below to adjust the angle of the limiting plate 15. The top of the rotating shaft is fixedly connected with the connecting plate 141, which rotates around the rotating shaft under the drive of the movable bolt 131 to transmit the motion and convert the sliding of the movable bolt 131 into the rotation of the rotating shaft. The connecting plate 141 is provided with a movable slot, which provides a sliding track for the movable bolt 131, allowing the sliding of the movable bolt 131 to be smoothly converted into the rotation of the connecting plate 141. The movable bolt 131 is movably connected in the movable slot and is linked with the connecting plate 141 through sliding in the movable slot to drive the rotating shaft to rotate. The lower side of the rotating shaft is fixedly connected with a limiting plate 15, which directly controls the conveying track of the batteries on the conveying assembly 121 through the change of the angle to realize accurate shunting of different types of batteries. Grooves are formed in the right side of the front and rear outer walls of the limiting plate 15, which provide mounting space for the springs 151 and the protective plates 152 to allow them to be stably mounted on the limiting plate 15. The grooves are uniformly fixedly connected with springs 151, which absorb impact force through elastic deformation when the battery contacts the limiting plate 15 to play a buffering role and reduce the collision force received by the battery. The outer end of the spring 151 is fixedly connected with a protective plate 152, which directly contacts the battery to further weaken the contact stress and effectively avoid appearance damage or performance degradation of the battery due to collision in cooperation with the spring 151. The right side of the fixed plate 14 of the top of the base 1 is fixedly connected with a battery identification piece 12,The battery identification part 12 can accurately identify the specifications, performance and other key parameters of the battery, and provide reliable basis for the subsequent sorting logic. The base 1 top baffle 11 is provided with a conveying assembly 121. The conveying assembly 121 is responsible for stably conveying the lithium ion battery to be sorted, and provides a conveying path for the identification and sorting of the battery.

[0028] In the second embodiment, the dropped battery is limited and placed by the placing plate 24, the first partition plate 25 and the side plate 26 during the movement process, and then is classified and collected by the second partition plate in the collecting box 3, so as to prevent the poor quality of the sorted and loaded tray, the chaotic state of the battery, the position deviation and the frequent stacking and tilting phenomenon, which directly interfere with the automatic docking of the subsequent assembly process and greatly reduce the overall smoothness of the production line.

[0029] As shown in Figure 5 Figure 6 The left ends of the base 1 top baffle 11 are fixedly connected with the fixed parts 2. The upper and lower parts of the base 1 top fixed part 2 are rotatably connected with the rotating rods 21. The front ends of the rotating rods 21 below the fixed parts 2 are fixedly connected with the servo motors. The outer ends of the rotating rods 21 are fixedly connected with the rotating rollers 22. The outer walls of the rotating rollers 22 are fixedly connected with the conveying belts 23. The conveying belts 23 are driven by the servo motors below the fixed parts 2. The rotating rollers 22 are driven to rotate by the rotating rods 21 to realize stable conveying. The conveying belts 23 are used to receive and convey the sorted batteries. The outer walls of the conveying belts 23 are uniformly fixedly connected with the placing plates 24. The placing plates 24 are used to receive the batteries. The middle parts of the placing plates 24 are fixedly connected with the first partition plates 25. The first partition plates 25 can divide the placing plates 24 into two areas. The two ends of the placing plates 24 are fixedly connected with the side plates 26. The side plates 26 limit the left and right deviation of the batteries to ensure that the batteries remain in an orderly state in the placing plates 24. The inner side of the base 1 top baffle 11 is fixedly connected with the collecting box 3. The collecting box 3 is used to receive the batteries transferred from the placing plates 24. The collecting box 3 is fixedly connected with the inclined plates 31. The inclined surfaces of the inclined plates 31 face the right side. The inclined plates 31 guide the batteries to slide along the inclined surfaces to the right side. The collecting box 3 is fixedly connected with the second partition plates. The second partition plates cooperate with the inclined plates 31 to realize the classified storage of different types of batteries. The two ends of the right side of the collecting box 3 are movably connected with the door plates. The outer walls of the door plates are fixedly connected with the handles. After the collection is completed, the classified batteries can be taken out by opening the door plates through the handles.
