[0011] When the present invention is working, the battery core material box containing the battery core is hoisted onto the upper conveying mechanism, the upper conveying mechanism pushes the battery core material box onto the battery core lifting assembly, and positions it on the battery core lifting assembly, and then uses the battery core clamping manipulator to take the battery core out of the battery core material box and transport it to the battery core scanning mechanism for standby use; the shell is loaded into the material box for standby use, the shell dust removal rotating seat is rotated so that the front side of the shell dust removal clamping plate faces upward, and the shell dust removal clamping cylinder is used to loosen the shell dust removal clamping plate, and the pneumatic suction cup is controlled by the three-axis driver to suck the shell from the material box to the shell dust removal clamping plate, the shell is clamped with the shell dust removal clamping plate, and the shell dust removal rotating seat is controlled to rotate 90° so that The opening of the shell faces downward, and the shell dust removal plate is controlled to rise and extend into the shell to clean the internal dust through the air jet hole.

[0012] Compared with the prior art, the beneficial effect of the present invention is that the automation level of battery cell shell insertion is greatly improved by using the present invention to implement battery cell shell insertion.
[0013] During operation, the battery cell box is pushed into the battery cell lifting assembly through the sprocket conveying mechanism in cooperation with the push rod and the guide rod. The guide rod ensures the smoothness of the battery cell box. Since the fully loaded battery cell box is heavy, in order to reduce the load pressure, the battery cell box is pushed by the push rod to reduce the power requirement; the unloaded battery cell box is greatly reduced in weight, and the use of a belt conveyor mechanism for conveying it can greatly reduce the conveying pressure while ensuring its conveying stability; at the same time, since the battery cell box is taken out by manual removal or hoisting, when the tail of the battery cell box is transported to the exit, in order to avoid the continuous thrust of the belt conveyor mechanism during transportation causing impact on the porter or hoisting equipment and injuring the worker or affecting the hoisting of the hoist, a separation cylinder is set at the exit to The material box is lifted up to separate the battery cell material box from the belt conveyor, and because the battery cell material box is empty at this time, the weight has been greatly reduced and the inertia is relatively small, which further ensures the feasibility and rationality of the scheme; in the working process, since the battery cells are placed in the battery cell material box, this has higher requirements on the stability of the lifting plate, and since the lifting slide bar is a rod-shaped structure, its stability as a supporting structure is relatively poor, the bottom of the lifting slide bar is fixed to the bottom plate, and the top of the lifting slide bar is connected to a connecting plate fixed on the conveyor frame, which ensures the overall stability of the lifting slide bar and then ensures the stability of the lifting plate, the slide seat is slidably set on the lifting slide bar through the pulley group and the connection method with the lifting rod, the synchronous shaft and the synchronous rod improves the stability of the connection while ensuring the smoothness of lifting.
[0014] As an improvement of the present invention, a pair of auxiliary devices are arranged on the base plate between the two pairs of lower lifting rods and the two pairs of lifting sliding rods. The auxiliary device comprises an auxiliary bracket fixed to the base plate, and a limiting bolt, a jacking cylinder and a pair of buffer cylinders are installed on the auxiliary bracket. Limiting baffles are arranged on both sides and the rear end of the lifting plate and the rear end of the base plate. A brake is arranged next to the conveying guide roller at the rear end of the lifting plate. The brake comprises a brake cylinder fixed on the brake seat, and the end of the brake cylinder is connected to the brake plate. The end surface of the brake plate is processed with an arc-shaped concave surface that cooperates with the conveying guide roller. A square hole is opened at the rear end of the middle part of the lifting plate, and a recovery mechanism is installed at the bottom of the lifting plate. The recovery mechanism comprises a recovery cylinder fixed to the bottom of the lifting plate, and recovery guide rails are arranged on both sides of the recovery cylinder. A recovery seat is slidably provided on the recovery guide rail, and a recovery push plate extending upward from the square hole is installed on the recovery seat, and the recovery push plate is connected to the piston rod of the recovery cylinder.
[0015] During operation, first of all, the limit bolt plays a limiting role. In order to avoid the lifting plate from impacting the limit bolt when it descends under the action of the driving cylinder, a buffer cylinder is set to greatly reduce the impact of the lifting plate on the limit bolt; at the same time, when the lifting plate descends to the lower limit position, due to the torque relationship, it is difficult to rely solely on the driving cylinder to extend the piston rod to push the lifting plate up. It can be smoother by using an auxiliary lifting cylinder to cooperate with the driving cylinder; in the initial state, the brake plate of the brake is attached to the rear end conveying guide roller, increasing the friction between the brake plate and the conveying guide roller. When the fully loaded battery cell box is transported from the upper conveying mechanism to the lifting plate under the action of the push rod, due to the heavy weight of the fully loaded battery cell box, it has a large inertia under the action of the push rod. If the battery cell box directly collides with On the limit baffle, the inertia effect will have a greater impact on the battery cells. Therefore, a brake is arranged next to the conveying guide roller at the rear end, and the friction between the brake plate and the conveying guide roller is adjusted by adjusting the pressure of the brake plate through the brake, so that the rear conveying guide rollers can play a better buffering role. At the same time, after the fully loaded battery cell box reaches the position, the brake plate is controlled to completely lock the conveying guide roller. The braked conveying guide rollers can also ensure that the battery cell box moves back and forth, affecting the clamping accuracy of the battery cell clamping assembly; when all the battery cells in the battery cell box are clamped and the battery cell box needs to be sent out, the brake must be unlocked; when the empty battery cell box is pushed into the lower conveying mechanism, the piston rod is retracted by the recovery cylinder, and the battery cell box is pushed into the lower conveying mechanism under the action of the recovery push plate.

[0017] When the shell-entering mechanism is working, the shell is first transferred from the shell dust removal mechanism to the upper shell mechanism by the second manipulator, the upper shell mechanism sends the shell into the through hole of the middle installation plate, and is fixed to the upper part of the shell by the shell positioning mechanism, and then the battery cell is transferred from the temporary storage frame to the battery cell surface treatment mechanism by the first manipulator, and the battery cell is pushed from the battery cell surface treatment mechanism into the shell through the battery cell guide mechanism by the second manipulator using an auxiliary pusher; the present invention adopts the bottom installation plate to cooperate with the upper shell mechanism and the second manipulator to transfer the shell to the bottom of the shell-entering support frame, so as to make full preparation for the subsequent shell entry, and at the same time, the battery cell and The assembly accuracy and stability of the shell are particularly important, so the shell positioning mechanism and the battery cell guiding mechanism are used to ensure its position accuracy and stability, the vacuum suction cup is used to position the top of the shell, and the battery cell guide rod and the battery cell guide wheel are used to ensure the directionality of the battery cell when entering the shell. Since there will be a very small amount of dust adsorbed on the battery cell during the robot's transportation process, the battery cell surface treatment mechanism is used to clean up the very small amount of dust on the surface of the battery cell. Since the robot will be affected by the space of the battery cell surface treatment mechanism when pushing the battery cell into the shell, the auxiliary pusher is used in conjunction with the robot to complete the one-time shell entry to ensure quality.

[0062] When the utility model is working, the battery cell material box fully loaded with battery cells is hoisted from the pallet to the upper conveying mechanism 11 through the hanger on the hanger; the sprocket conveying mechanism 113 is used to push the battery cell material box to slide onto the lifting component 2 through the push rod 115 and the guide rod 118, and it is buffered and stopped at the tail end of the lifting plate 24 under the action of the brake 28, and the positioning is completed under the action of the brake 28; the battery cells of the battery cell material box are taken out one by one by the clamping manipulator 33 in the clamping component 3 and sent to the temporary storage station 5112 for standby; the shell is loaded into the material box 412 for standby, and the shell dust removal rotating seat 423 is rotated so that the front side of the shell dust removal clamp 425 faces upward, and the shell dust removal clamp is used to clamp the battery cell box. The tightening cylinder 424 releases the shell dust removal clamp 425, and controls the pneumatic suction cup 432 through the three-axis driver 431 to suck the shell from the material box 412 onto the shell dust removal clamp 425, and uses the shell dust removal clamp 425 to clamp the shell, and controls the shell dust removal rotating seat 423 to rotate 90° so that the opening of the shell faces downward, and controls the shell dust removal plate 426 to rise and extend into the shell, and clean the internal dust through the air jet hole 4261. After cleaning, the shell dust removal plate 426 is controlled to descend, and the shell dust removal rotating seat 423 is controlled to rotate 180° so that the opening of the shell faces upward, waiting to be loaded with the battery cell; use the first grasping manipulator 54 to transfer the scanned battery cell to the battery cell dust removal mechanism 52, and remove After the dust is removed, the battery is transferred to the temporary storage frame 53. When entering the shell, the shell is first transferred from the shell dust removal mechanism 42 to the upper shell mechanism 622 by the second manipulator. The upper shell mechanism 622 sends the shell into the through hole 6214 of the middle mounting plate 6212 and is fixed to the upper part of the shell by the shell positioning mechanism 623. The battery cell is then transferred from the temporary storage frame to the battery cell surface treatment mechanism 625 by the first manipulator, and the battery cell is pushed from the battery cell surface treatment mechanism 625 into the shell through the battery cell guide mechanism 624 by the second manipulator using the auxiliary pusher 626. When all the batteries in the battery cell material box are taken out, the lifting plate 24 is controlled to descend by the lifting assembly 2 and be flush with the lower conveying mechanism 12. Unlock the brake 28, control the recovery cylinder 291 to move, and push the battery cell box onto the lower conveying mechanism 12 through the recovery push plate 294. After the battery cell box enters the lower conveying mechanism 12, the lifting cylinder 263 of the auxiliary device 26 cooperates with the driving cylinder 245 to control the lifting plate 24 to rise to the same level as the upper conveyor; use the belt conveyor mechanism 122 to send the empty battery cell box out from the exit, and when the end of the battery cell box approaches the exit, control the separation cylinder 124 to work, lift the tail of the battery cell box to separate it from the belt conveyor mechanism 122, and then move or lift the empty battery cell box away; lift the next satisfying battery cell box onto the upper conveying mechanism 11, and repeat this process.
[0063] During operation, the sprocket conveying mechanism 113 cooperates with the push rod 115 and the guide rod 118 to push the battery cell material box into the battery cell lifting assembly 2. The guide rod 118 ensures the smoothness of the battery cell material box. Since the battery cell material box is heavy under full load, in order to reduce the load pressure, the battery cell material box is pushed by the push rod 115 (rather than the conveyor belt or other similar power directly), which reduces the power requirement; the design of the side bending plate 1142 and the T-shaped push rod mounting seat 116 ensures that the power transmission between the push rod 115 and the sprocket conveying mechanism 113 is more reliable, the structural strength is higher, and the stability is better; after the battery cells in the battery cell material box are taken out, the empty battery cell material box is greatly reduced in weight, and the belt conveyor is used The conveying mechanism 122 greatly reduces the conveying pressure while ensuring its conveying stability, and the contact mode between the belt and the battery cell box during belt conveying has better synchronization, and the influence of inertia is relatively small; at the same time, since the battery cell box is taken out by manual removal or hoisting, when the tail of the battery cell box is conveyed to the exit, in order to avoid the continuous thrust of the belt conveyor mechanism 122 during transportation to cause impact on the porters or hoists and injure the workers or affect the hoisting of the hoist, a separation cylinder 124 is set at the exit to lift the battery cell box, so that the battery cell box is separated from the belt conveyor mechanism 122, and because the battery cell box is unloaded at this time, the weight has been greatly reduced and the inertia is relatively small, which further ensures the feasibility and rationality of the scheme.
[0064] In actual use, since the battery cells are placed in the battery cell box, higher requirements are placed on the stability of the lifting plate 24. Since the lifting slide bar 22 is a rod-shaped structure, its stability as a supporting structure is relatively poor. The bottom of the lifting slide bar 22 is fixed to the bottom plate 21, and the top of the lifting slide bar 22 is connected to a connecting plate 23 fixed on the conveyor frame 7, thereby improving the overall stability of the lifting slide bar 22 and thus ensuring the stability of the lifting plate 24. The slide seat 25 is slidably set on the lifting slide bar 22 via the pulley group 251 and is connected to the lifting rod, the synchronization shaft 243, and the synchronization rod 244. The stability of the connection is also improved under the premise of ensuring the smoothness of lifting. During the lifting and lowering of the lifting plate 24, the limit bolt 262 of the auxiliary device 26 plays a limiting role. In order to avoid the lifting plate 24 from impacting the limit bolt 262 when it is lowered under the action of the driving cylinder 245, the buffer cylinder 264 is provided to greatly reduce the impact of the lifting plate 24 on the limit bolt 262. At the same time, when the lifting plate 24 is lowered to the lower limit position, it is difficult to push the lifting plate 24 up by extending the piston rod by the driving cylinder 245 alone due to the torque relationship. By using the auxiliary lifting cylinder 263 cooperates with the driving oil cylinder 245 to make it smoother; when the battery core material box is sent from the upper conveying mechanism 11 to the lifting plate 24, the brake 28 in the initial state locks the rear conveying guide roller 112. When the fully loaded battery core material box is transported from the upper conveying mechanism 11 to the lifting plate 24 under the action of the push rod 115, due to the heavy weight of the fully loaded battery core material box, it has a large inertia under the action of the push rod 115. If the battery core material box directly collides with the limit baffle 27, the inertia will have a great impact on the battery core. Therefore, by arranging a brake 28 beside the rear conveying guide roller 112, the brake 28 adjusts the pressure of the brake plate 283 to adjust the friction between the brake plate 283 and the conveying guide roller 112, so that the rear conveying guide rollers 112 play a better buffering role. At the same time, after the fully loaded battery core material box arrives at the position, the brake plate 283 is controlled to completely lock the conveying guide roller 112, and the braked conveying guide rollers 112 can also ensure that the battery core material box moves back and forth, thereby improving the battery core clamping assembly 3 to clamp precision and clamping efficiency; when all the cells in the cell box are clamped and the cell box needs to be sent out, the brake 28 must be unlocked, and the surface of the brake plate 283 in the brake 28 can be pasted with a felt plate or made of a material whose friction can be easily changed with pressure, so as to further ensure the function of the brake 28; when the empty cell box is pushed into the lower conveying mechanism 12, the piston rod is retracted by the recovery cylinder 291, and the cell box is pushed into the lower conveying mechanism 12 under the action of the recovery push plate 294.
