Description

Technical Field

[0001] This disclosure relates to the field of battery technology, and more particularly to an automated battery assembly production line. Background Technology

[0002] Currently, there are many types of batteries on the market, and the battery manufacturing process is quite complicated. In particular, the battery assembly stage often adopts automated processes, and there are various types of battery assembly devices in existing technologies.

[0003] For example, the fully automated lithium-manganese battery production line with Chinese invention patent application number CN201410013306.0 includes: a cylindrical battery loading robot containing electrolyte, a cap loading device, a cap welding device, a cap pressing device, a cap in-situ detection device, and a battery unloading device arranged sequentially around an eight-station intermittent turntable; wherein, the cap pressing device mainly consists of a robot, a left push cylinder, a right push cylinder, a left arc-shaped limiting block, a right arc-shaped limiting block, a downward push cylinder, and a downward pressing block. The robot bends the cap downward, tilting the shape of the cap after bending. The left and right push cylinders respectively push the right and left arc-shaped limiting blocks to the top sides of the cylindrical battery, and the downward push cylinder pushes the downward pressing block downward, pressing the cap onto the top of the cylindrical battery. The eight-station intermittent turntable rotates one station.

[0004] The production line lacks electrode tab correction and shaping processes, resulting in misalignment of the welding points between the electrode tab and the cap, which compromises the accuracy and stability of the welding between the cap and the electrode tab.

[0005] Furthermore, the cap pressing device in the patent document is fully assembled in one station, and the cap pressing device is located from... Figure 1 As can be seen, the robotic arm is positioned above the battery and is also vertical. If the robotic arm operates vertically, it bends the cap downwards; if the robotic arm moves vertically, it bends the cap downwards and then lifts it away. Alternatively, if the robotic arm moves horizontally, it bends the cap downwards and then moves it away. The left and right arc-shaped limiting blocks and pressure blocks then move to press the cap down onto the top of the cylindrical battery. This patent document does not disclose the structure and operation of the robotic arm, the left and right arc-shaped limiting blocks, and the pressure blocks. If the robotic arm moves vertically, acting on the sidewall of the cap, it may not be able to bend the cap. Furthermore, the combination of these three components results in a complex structure.

[0006] The cap pressing device is just one process on the battery assembly line. Therefore, the existing problems in battery assembly require a more stable and efficient battery assembly production line. Utility Model Content

[0007] The purpose of this disclosure is to provide an automated battery assembly production line, thereby solving the aforementioned problems existing in the prior art.

[0008] To achieve the above objectives, the technical solutions adopted in the embodiments of this disclosure are as follows:

[0009] This disclosure provides an automated battery assembly production line, comprising: a rotating mechanism with a plurality of slotted stations evenly arranged thereon, the slotted stations being used to hold batteries to be assembled, so that the rotating mechanism carries the batteries to be assembled in rotation; a tab correction mechanism, the tab correction mechanism being disposed on one side of the rotating mechanism, for correcting the tabs of the batteries to be assembled, so that the tabs are in a preset position; a tab shaping mechanism, the tab shaping mechanism being disposed on one side of the rotating mechanism, downstream of the tab correction mechanism, for shaping and flattening the tabs; a cap welding mechanism, the cap welding mechanism being disposed on one side of the rotating mechanism, downstream of the tab shaping mechanism, for welding an inner cap of the battery to be assembled onto the tabs; and a cap pressing mechanism, the cap pressing mechanism being disposed on one side of the rotating mechanism, downstream of a first detection mechanism, for closing the inner cap onto the opening of the battery to be assembled.

[0010] For example, the tab correction mechanism includes a rubber wheel disposed on one side of the rotating mechanism, corresponding to a corresponding slot, for clearance engagement with the battery to be assembled; a limiting member disposed on the side of the battery to be assembled opposite to the rubber wheel, the limiting member having a groove in the horizontal direction and a limiting groove in the vertical direction for engaging with the battery to be assembled, with rollers respectively disposed in the grooves at both ends of the limiting groove; when correcting the tab, the limiting member moves toward the battery to be assembled, clamping the battery between the limiting member and the rubber wheel, the rollers and the rubber wheel respectively abutting against the battery to be assembled, so that the rotation of the rubber wheel drives the battery to be assembled to rotate; and a detection member that can extend into the opening of the battery to be assembled to detect whether the tab has reached a preset position.

[0011] For example, the tab shaping mechanism includes: a fixed base, which is disposed on one side of the rotating mechanism and corresponds to the corresponding slot; a finger cylinder, which is disposed on the fixed base and can move up and down above the corresponding slot of the rotating mechanism. The two protruding ends of the finger cylinder are respectively provided with opposing clamping teeth, which close and open under the drive of the finger cylinder. When the battery to be assembled is rotated to the bottom of the finger cylinder, the finger cylinder moves down, the tab enters between the two clamping teeth, and the finger cylinder closes to squeeze the tab flat.

[0012] For example, the welding cover mechanism includes: a support base disposed on one side of the rotating mechanism; an inner cover collecting component, which is movable horizontally and vertically relative to the support base; the inner cover collecting component includes: two spaced clamps with a tension spring between them; when the inner cover collecting component is in a first position, the openings of the two clamps correspond to the openings of the inner cover conveying mechanism to obtain the inner cover; when the inner cover collecting component is in a second position, the two clamps hold the inner cover on the opening of the battery to be assembled; and a limiting rod disposed on the corresponding battery to be assembled. One side of the battery tab, its end can move toward the corresponding battery tab under the action of the corresponding driving mechanism; the welding gun, the welding gun is set on the other side of the battery tab to be assembled, opposite to the limiting rod, its end can move toward the corresponding battery tab to be assembled under the action of the corresponding driving mechanism; when the two clamps hold the inner cover at the opening of the battery to be assembled and on one side of the tab, the limiting rod and the welding gun move toward the battery tab to be assembled respectively, and their ends abut against one side of the inner cover and the other side of the tab respectively, the welding gun works, and welds the inner cover to the tab.

[0013] For example, the capping mechanism includes: a transverse stop bar, disposed above the rotating mechanism and located above the inner cover, for tilting the transverse stop bar when the inner cover passes through; two robotic arms, the opposite sides of which are provided with grooves that cooperate with the battery to be assembled, for clamping the opposite sides of the battery to be assembled, so that the tilted inner cover enters the opening of the battery to be assembled; and a capping component, for pressing the tilted inner cover into the opening of the battery to be assembled.

[0014] For example, the production line further includes: a first detection mechanism, which is disposed on one side of the rotating mechanism and located upstream of the tab correction mechanism, for detecting whether there is a battery to be assembled at the corresponding slot station.

[0015] For example, the production line further includes a second inspection mechanism, which is disposed on one side of the rotating mechanism and upstream of the capping mechanism, for detecting whether there is an inner cover on the battery to be assembled.

[0016] For example, the production line further includes a feeding conveying mechanism, which is disposed on one side of the rotating mechanism, with one end of its port fitting against the rotating mechanism, for conveying the battery to be assembled into the slot.

[0017] For example, the production line further includes: a material picking device, which is located at the end of the production line and corresponds to a corresponding slot, for picking up the assembled battery self-rotating mechanism; and a material discharging conveyor, which is located below the material picking device and is used to catch the battery picked up by the material picking device.

[0018] For example, the rotating mechanism includes: a disc and a motor, wherein the disc has slots evenly spaced along its circumferential edge, and the motor drives the disc to rotate around a central axis; the tab correction mechanism, the tab shaping mechanism, the welding cap mechanism, and the cap pressing mechanism are sequentially arranged along the edge of the disc's rotation direction; as the disc rotates, each mechanism sequentially performs corresponding actions on the battery to be assembled in the corresponding slot.

[0019] The beneficial effects of the embodiments disclosed herein are:

[0020] The battery automated assembly production line of this disclosure is equipped with a tab correction and tab shaping mechanism, which makes the welding of the tab and the inner cover accurate and stable, and improves the yield. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the embodiments of this disclosure and are not intended to limit the embodiments of this disclosure.

[0028] like Figure 2 As shown in the figure, this disclosure proposes an automated battery assembly production line, which includes: a rotating mechanism 100 with a plurality of slotted stations evenly arranged thereon, the slotted stations being used to hold the batteries to be assembled, so that the rotating mechanism 100 carries the batteries to be assembled and rotates; a tab correction mechanism 200, the tab correction mechanism 200 being disposed on one side of the rotating mechanism 100, for correcting the tabs of the batteries to be assembled, so that the tabs are in a preset position; a tab shaping mechanism 300, the tab shaping mechanism 300 being disposed on one side of the rotating mechanism 100, downstream of the tab correction mechanism 200, for shaping the tabs and flattening the tabs; a cap welding mechanism 400, the cap welding mechanism 400 being disposed on one side of the rotating mechanism 100, downstream of the tab shaping mechanism 300, for welding the inner cap of the battery to be assembled onto the tabs; and a cap pressing mechanism 920, the cap pressing mechanism 920 being disposed on one side of the rotating mechanism 100, downstream of the detection mechanism, for closing the inner cap onto the opening of the battery to be assembled.

[0029] In the production line of this embodiment, a rotating mechanism is disposed on a workbench. The rotating mechanism includes a drive motor and a rotating table. The rotating table can be disposed on the workbench, and the drive motor is disposed below the workbench. The rotating table can be configured according to actual conditions. The drive motor can drive the rotating table to rotate through a transmission component or directly drive the rotating table to rotate. Multiple slot stations are evenly arranged on the rotating mechanism. The tab correction mechanism, the tab shaping mechanism, the cap welding mechanism, and the cap pressing mechanism are sequentially disposed on the workbench and located on one side of the rotating mechanism, with each mechanism corresponding to a corresponding slot station. The rotating mechanism moves one station sequentially according to the process sequence, so that each mechanism sequentially performs corresponding actions on the battery to be assembled at the corresponding slot station. Each mechanism is connected to and controlled by a PLC. The spacing between the mechanisms can be configured according to actual conditions. In this embodiment, the tab correction mechanism rotates the battery to be assembled to position the tab in a preset position, and the tab shaping mechanism flattens the tab surface by pressing it. After correction and shaping, the tab is easier to weld to the inner cover, resulting in a stronger weld and reducing the defect rate.

[0030] like Figure 2As shown, the production line further includes a first detection mechanism 500 before the electrode correction mechanism. The first detection mechanism 500 is located on one side of the rotating mechanism 100. When the slot station of the rotating mechanism 100 rotates to the front of the first detection mechanism 500, the first detection mechanism 500 detects whether there is a battery to be assembled at this slot station.

[0031] The first detection mechanism in this embodiment can be a proximity switch. If there is a battery to be assembled at the slot station, the proximity switch's sensing surface detects the battery before the slot station rotates to the first detection mechanism. The rotation mechanism then rotates, causing the slot station to move to the next position. The electrode correction mechanism at the next position corrects the electrode's position, placing it in a preset position. Similarly, the electrode correction mechanism includes an electrode detection mechanism to detect whether the electrode has rotated to the preset position. The electrode detection mechanism can be a fiber optic through-beam sensor.

[0032] The first detection mechanism 500 includes a first fixed frame 510 and a proximity switch 520. The first fixed frame 510 is disposed on the workbench and is opposite to a slot position of the rotating mechanism 100. The first fixed frame 510 has a mounting port near its lower part, through which the proximity switch 520 passes. The proximity switch is electrically connected to a PLC. The detection end of the proximity switch extends from the mounting port toward the slot position. The proximity switch is located in the lower middle part of the battery. When a battery is present in the slot position, the sensing surface is in clearance fit with the battery. When a battery to be assembled is present in the slot position, the slot position rotates with the rotating mechanism to the proximity switch, detects the battery, and sends feedback to the PLC. The rotating mechanism continues to rotate to the next slot position, and the proximity switch continues to detect the next slot position. If no battery is present in the slot position, after the rotating mechanism rotates, when the slot position rotates to the subsequent mechanisms, the other subsequent mechanisms do not perform any actions.

[0033] The production line also includes a second inspection mechanism 600, which is located between the welding cover mechanism 400 and the pressing cover mechanism 920, and is used to detect whether there is an inner cover on the battery to be assembled.

[0034] like Figure 2As shown, the second detection mechanism includes: a vertical fixing frame (not shown), a horizontal crossbeam (not shown), an L-shaped mounting bracket (not shown), and an inner cover detection component (not shown). One end of the vertical fixing frame is mounted on the worktable and located on one side of the rotating mechanism. The other end of the vertical fixing frame is connected to one end of the horizontal crossbeam. The other end of the horizontal crossbeam is equipped with an L-shaped mounting bracket, with the outer side of the bent portion of the L-shaped mounting bracket facing the rotating mechanism and located on the rotating mechanism. The inner cover detection component is located on the inner side of the bent portion facing the corresponding slot, and its height is consistent with the height of the inner cover, to detect whether there is an inner cover on the battery to be assembled. A pull-out mechanism is correspondingly provided at this slot station. The structure of the pull-out mechanism can be the same as that of the material handling device. If no inner cover is detected, the pull-out mechanism pulls the battery out of the slot station and it falls into the hole in the worktable into the tray below. The empty slot station then moves to the next mechanism, which may not perform any action.

[0035] The inner cover detection component can be a fiber optic through-beam sensor. During detection, the infrared light emitted is directed away from the rotating mechanism. The L-shaped mounting bracket is positioned above the corresponding slot. The height of the L-shaped mounting bracket is greater than the combined height of the battery to be assembled and the inner cover when upright, so that the battery can pass under the L-shaped mounting bracket.

[0036] like Figure 2 As shown, the rotating platform of the rotating mechanism can preferably be disc-shaped, as a disc-shaped rotating mechanism saves more space. The drive motor can be located below the worktable, and its drive shaft is connected to the central axis of the disc, causing the disc to rotate around the central axis under the drive of the motor. Multiple slot positions are evenly spaced along the circumferential edge of the disc. The first detection mechanism, the tab correction mechanism, the tab shaping mechanism, the cap welding mechanism, the second detection mechanism, the pull-out mechanism, and the cap pressing mechanism are sequentially arranged along the edge of the disc's rotation direction and correspond to the respective slot positions. As the disc rotates, each mechanism sequentially performs corresponding actions on the batteries to be assembled in the slots. Each rotation of the disc moves one slot position, allowing each mechanism to sequentially perform corresponding actions on the batteries in the corresponding slots.

[0037] like Figure 2 As shown, the slot is an arc-shaped groove. The rear arc surface along the direction of disk rotation is slightly longer than the front arc surface, allowing the rear arc surface to push the battery to be assembled to move when the disk rotates, and making it easy to remove the battery. By connecting the end of the rear arc surface of the slot with the end of the front arc surface of the next slot, the edge of the disk forms a wavy arc structure.

[0038] like Figure 3As shown, the electrode correction mechanism includes: a rubber wheel 210, disposed on one side of the rotating mechanism 100, i.e., one side of the disc, corresponding to a corresponding slot, for clearance engagement with the battery to be assembled; a limiting member 220, disposed on the side of the battery to be assembled opposite to the rubber wheel 210, the limiting member 220 having a groove in the horizontal direction and a limiting groove in the vertical direction that engages with the battery to be assembled, and rollers 221 respectively disposed in the grooves at both ends of the limiting groove; when correcting the electrode, the limiting member 220 moves toward the battery to be assembled, clamping the battery between the limiting member 220 and the rubber wheel 210, the rollers 221 and the rubber wheel 210 respectively abutting against the battery to be assembled, so that the rotation of the rubber wheel 210 drives the battery to be assembled to rotate; and a detection member 230, which can extend into the opening of the battery to be assembled to detect whether the electrode has reached a preset position.

[0039] Specifically, the electrode correction mechanism is arranged adjacent to the first detection mechanism. One end of the first fixed frame of the first detection mechanism is fixed to the workbench. A proximity switch is arranged near the bottom of the first fixed frame, and a mounting platform facing the rotating mechanism is arranged near the top. A detection platform that can move up and down is arranged below the mounting platform. A detection component, namely the electrode detection mechanism, is arranged at the end of the detection platform facing the electrode correction mechanism. The detection component is opposite to the battery to be assembled below.

[0040] The mounting platform has a telescopic mechanism in its central area and openings on both sides of the telescopic mechanism. The telescopic mechanism is connected to two support rods, one end of which passes through a corresponding opening, and the other end of each support rod is connected to the testing platform. The telescopic mechanism can be a cylinder. Because the electrode correction mechanism is located adjacent to the first testing mechanism, and their corresponding slots are adjacent, the testing platform does not need to be too large.

[0041] The electrode correction mechanism 200 further includes: a fixed bracket 240, a drive mechanism 250, and a connector 260. One end of the fixed bracket 240 is located on the side of the rubber wheel 210 away from the rotating mechanism 100. The other end of the fixed bracket 240 is provided with two drive rods that can slide on the fixed bracket 240, and the ends of the two drive rods are provided with connecting blocks. The drive mechanism 250 is located on the other end of the fixed bracket 240 away from the rotating mechanism 100. The drive mechanism 250 can drive the two drive rods to move horizontally toward or away from the rotating mechanism 100. The drive mechanism 250 can be a cylinder. The rubber wheel 210 is driven by a motor, and the motor driving the rubber wheel 210 can be located below the worktable.

[0042] The connecting block is connected to the connecting member. The bottom of the connecting member is provided with the limiting member. The connecting member includes a horizontal member and a vertical member that are connected to each other. The horizontal member spans the rubber wheel and the slot station. The vertical member is located above the rotating mechanism and is located on both sides of the corresponding slot station, separate from the rubber wheel. The bottom of the vertical member is provided with a limiting member facing the slot station. The limiting member is suspended on the surface of the rotating mechanism. The limiting member has a groove in the horizontal direction and a limiting groove in the vertical direction to cooperate with the battery to be assembled. Rollers are respectively provided in the grooves at both ends of the limiting groove. When the card slot carrying the battery to be assembled moves to the tab correction mechanism, the detection platform moves downward a certain distance under the drive of the telescopic mechanism and support rod. The detection component enters the opening of the battery to be assembled, and the detection probe is fixed in position within the detection component to detect whether there is a tab at the preset position of the opening of the battery to be assembled. If a tab is found, the drive mechanism of the tab correction mechanism drives the connecting component to move towards the battery to be assembled, so that the limiting groove of the limiting component engages with the battery to be assembled. The rollers and rubber wheels on both sides of the limiting groove abut against the battery to be assembled. The rubber wheels rotate, causing the battery to be assembled to rotate until the detection component detects the tab. The rubber wheels stop rotating, the detection platform moves upward, and the connecting component moves away from the battery to be assembled. The detection component and the limiting component simultaneously leave the battery to be assembled under the action of the corresponding drive mechanism. The rotating mechanism then transfers the battery to the next mechanism. The detection platform is located below the horizontal component, so the two drives do not interfere with each other. If the battery rotates one revolution and no tab is detected, the detection stops, and the next process begins. The rotating mechanism rotates with the battery, and the subsequent mechanisms do not perform their corresponding actions.

[0043] like Figure 3 As shown, the tab shaping mechanism includes: a fixed base 310, which is disposed on one side of the rotating mechanism 100 and corresponds to the corresponding slot; and a finger cylinder 320, which is disposed on the fixed base 310 and can move up and down above the corresponding slot of the rotating mechanism 100. The two protruding ends of the finger cylinder 320 are respectively provided with opposing clamping teeth 321. The two clamping teeth close and open under the drive of the finger cylinder. When the battery is rotated to the position below the finger cylinder 320, the finger cylinder 320 moves down, and the tab enters between the two clamping teeth 321. The two clamping teeth 321 close to squeeze the tab flat.

[0044] Specifically, the fixed base is equipped with a drive cylinder, the drive end of which is connected to a finger cylinder to drive the finger cylinder to move up and down. The drive end of the finger cylinder is connected to clamping teeth, and the clamping surfaces of the two clamping teeth are opposite to each other.

[0045] like Figure 2As shown, the production line also includes: a vibrating feeder 910, which has a receiving cavity inside, and a spiral storage platform is provided on the side wall of the receiving cavity to store the inner cover. The lowest point of the spiral storage platform is provided with a conveying port; an inner cover conveying mechanism 911, one end of which is connected to the conveying port, and the other end faces the corresponding slot of the rotating mechanism 100 and is close to the welding cover mechanism 400. The other end of the inner cover conveying mechanism 911 has an upward opening to provide the inner cover to the welding cover mechanism 400.

[0046] In this embodiment, the inner cover is supplied to the welding cover mechanism via a vibrating feeder and an inner cover conveying mechanism. The inner cover is sequentially conveyed to the inner cover conveying mechanism under the vibration of the vibrating feeder. The vibrating feeder is prior art and will not be described in detail here. A through hole is provided on the bottom wall opposite the upward-facing opening at the other end of the inner cover conveying mechanism. A push rod is provided below the through hole. When the inner cover collection piece moves to the opening, the push rod pushes the inner cover upwards, moving it out of the opening and into the inner cover collection piece of the welding cover mechanism.

[0047] like Figure 4 As shown, the welding cover mechanism includes: a support base 410, disposed on one side of the rotating mechanism 100; an inner cover collecting component 420, which can move horizontally and vertically relative to the support base 410; the inner cover collecting component 420 includes: two spaced clamps 421, with a tension spring 422 between the two clamps 421; when the inner cover collecting component 420 is in the first position, the openings of the two clamps are used to correspond to the opening of the inner cover conveying mechanism 911 to obtain the inner cover; when the inner cover collecting component 420 is in the second position, the two clamps 421 clamp the inner cover onto the opening of the battery to be assembled; and a limiting rod 423. 23 is set on one side of the corresponding battery tab to be assembled, and its end can move towards the corresponding battery tab under the action of the corresponding driving mechanism; welding gun 424 is set on the other side of the battery tab to be assembled, opposite to the limiting rod 423, and its end can move towards the corresponding battery tab under the action of the corresponding driving mechanism; when the two clamps 421 clamp the inner cover at the opening of the battery to be assembled and on one side of the tab, the limiting rod 423 and the welding gun 424 move towards the tab of the battery to be assembled respectively, and their ends abut against one side of the inner cover and the other side of the tab respectively. The welding gun 424 works to weld the inner cover to the tab.

[0048] Specifically, one end of the support base is fixed to the workbench and located on one side of the rotating mechanism. The other end of the support base is provided with a horizontal limiting frame. A movable mounting block is provided inside the horizontal limiting frame. A horizontal driving mechanism is provided outside the horizontal limiting frame. The driving end of the horizontal driving mechanism passes through the horizontal limiting frame and connects to the mounting block to drive the mounting block to move horizontally. A horizontal plate is provided at the bottom of the mounting block. A vertical cylinder and through holes on both sides of the vertical cylinder are provided on the horizontal plate. A telescopic rod is passed through each through hole. The vertical cylinder drives the telescopic rod to move up and down. The bottom end of each telescopic rod is connected to an inner cover collection component. The inner cover collection component includes: two clamps spaced apart. A tension spring is provided between the two clamps. The distance between the tension spring and the end of the clamp is slightly larger than the diameter of the inner cover. The shortest distance between the two clamps is slightly smaller than the diameter of the inner cover.

[0049] When the inner cover collection component is in the first position, the openings of the two clamps correspond to the opening of the inner cover conveying mechanism. The push rod below the opening of the inner cover conveying mechanism pushes the inner cover between the two clamps. Due to the action of the tension spring, the two clamps clamp the inner cover to obtain it. When the inner cover collection component is in the second position, the two clamps hold the inner cover on the opening of the battery to be assembled, and it is located on the side of the electrode facing the battery to be assembled. The electrode is generally located at the edge. That is to say, the horizontal drive mechanism and the vertical cylinder drive the inner cover collection component to move in the first and second positions. The horizontal drive mechanism drives the inner cover collection component to move horizontally to the opening of the inner cover conveying mechanism. After obtaining the inner cover, it moves horizontally back to the original position. The vertical cylinder drives the inner cover collection component to move to the corresponding opening of the battery to be assembled. At this time, the inner cover is located on the side of the electrode facing the battery.

[0050] The limiting component and welding torch are each connected by a corresponding drive mechanism. The longitudinal drive mechanism drives both components to move towards and away from the rotating mechanism. When they move close to the rotating mechanism and their ends are positioned on either side of the electrode tab, the horizontal drive mechanism drives them to move towards each other, clamping the inner cover and the electrode tab. At this point, the two clamps are removed, and the welding torch welds the electrode tab to the inner cover. After welding, the two components move towards each other in the horizontal direction, and then move away from the rotating mechanism to avoid obstructing the inner cover's movement to the next station.

[0051] After the inner cover collecting component moves the inner cover onto the opening of the battery to be assembled, the limiting component and welding gun actuate, contacting the inner cover. The inner cover collecting component then moves back to the first position, and simultaneously, the welding gun performs welding. After welding, the limiting component and welding gun separate and move away, and this process is repeated. The movement relationship between the inner cover collecting component, the limiting component, and the welding gun can be set according to actual conditions, and will not be elaborated here. The connection relationship between the limiting component, the welding gun, and the drive mechanism can be set according to actual conditions, and will not be elaborated here.

[0052] like Figure 2 As shown, a capping mechanism is provided downstream of the second testing mechanism. Before capping, the inner cap needs to be offset. The production line of this embodiment is implemented using a transverse baffle 930.

[0053] The capping mechanism 920 includes: a transverse stop 930, disposed above the rotating mechanism 100 and located above the inner cover, used to tilt the transverse stop when the inner cover passes by; two robotic arms, the opposite sides of which are provided with grooves that cooperate with the battery to be assembled, used to clamp the opposite sides of the battery to be assembled, so that the tilted inner cover enters the opening of the battery to be assembled; and a capping component, used to press the tilted inner cover into the opening of the battery to be assembled.

[0054] In this embodiment, one end of the transverse stop is fixed to a bracket, which is located on one side of the rotating mechanism. The other end of the transverse stop faces the rotating mechanism and is positioned above the inner cover. As the rotating mechanism rotates and the battery to be assembled moves, the transverse stop causes the inner cover to tilt outward. This tilting of the inner cover towards the battery facilitates pressing the cover in place.

[0055] The capping mechanism of this embodiment further includes a driving mechanism, which is connected to one end of two robotic arms. The opposing sides of the two robotic arms are respectively provided with grooves. When the two robotic arms are closed, the two grooves engage with the battery to be assembled, and the cap moves downward to press the inner cover into the opening of the battery to be assembled. Two driving mechanisms can be provided, each driving a corresponding robotic arm.

[0056] like Figure 2 As shown, the production line also includes a feeding conveying mechanism 700, which is disposed on one side of the rotating mechanism 100 and corresponds to the corresponding slot. One end of the feeding conveying mechanism 700 is in contact with the rotating mechanism 100 and is used to convey the battery to be assembled into the slot.

[0057] When any empty slot rotates to the port of the feeding conveyor mechanism, the bottom conveyor belt of the feeding conveyor mechanism moves a certain distance toward the rotating mechanism, so that the battery to be assembled on the conveyor belt enters the corresponding slot. The rotating mechanism rotates and takes away the battery. When the next slot corresponds to the port of the feeding conveyor mechanism, the battery is repeatedly fed into the slot.

[0058] like Figure 2 As shown, the production line also includes: a material handling device 800, which is located at the end of the production line and corresponds to a corresponding slot, for taking out the assembled battery self-rotating mechanism 100; and a discharge conveying mechanism 900, which is located below the material handling device 800 and is used to catch the battery taken out by the material handling device 800.

[0059] Specifically, the material handling device 800 includes a U-shaped limiting block 810 and a take-out component 820. The U-shaped limiting block 810 is disposed on the worktable, located on one side of the rotating mechanism 100. The U-shaped groove of the U-shaped limiting block 810 corresponds to the corresponding slot, and the bottom wall of the U-shaped limiting block 810 is provided with a notch. The take-out component can be a pull rod structure. One end of the take-out component 820 is connected to the driving mechanism, and the other end passes through the notch and can slide horizontally in the U-shaped groove. One end of the take-out component 820 is provided with a magnet with an inwardly concave arc groove 830, which matches the assembled battery. The assembled battery rotates with the rotating mechanism to the front of the U-shaped limiting block. The take-out component moves towards the slot, and the arc groove fits with the assembled battery. The magnet in the arc groove attracts the battery, and under the action of the driving mechanism, the battery is moved away from the rotating mechanism. A drain is located near the bottom wall of the U-shaped groove on the worktable. As the battery moves to the drain, the removed component continues to move away from the rotating mechanism. Due to the obstruction of the bottom wall of the U-shaped groove, the battery detaches from the arc-shaped groove of the removed component. The assembled battery then leaks out through the drain and enters the discharge conveyor mechanism below. The discharge conveyor mechanism transports the assembled battery to the next process. The specific structure of the discharge conveyor mechanism can utilize an existing moving platform, which will not be elaborated here.

[0060] Both the feeding and discharging conveyors can be driven by motors and transmission mechanisms, such as chains and gears, to achieve feeding and discharging.

[0061] The above description is only a preferred embodiment of the present disclosure. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present disclosure, and these improvements and modifications should also be considered within the protection scope of the present disclosure.
