In order to facilitate differentiation or identification of other production information of the battery, it is necessary to engrave a code on the outer wall of the battery shell.

[0003] It is now necessary to perform coding operations on the bottom surface of the battery shell. In order to avoid missing coding, the existing assembly line adopts a single-channel transmission method, and a current limiting structure is set on the transmission channel to block the shell so that the shell can be sent to the coding machine one by one for coding operations.

[0036] See also Figure 1 A coding device 10 includes: a mirror feeding mechanism 100, a coding machine 200, a flipping device 300 and a tray loading mechanism 400 which are sequentially arranged along the shell conveying direction. The mirror feeding mechanism 100 is provided with two shell feeding positions, which increases the feeding position of the shell 20, so that the shell 20 entering the working range of the coding machine 20 per unit time is doubled, thereby improving the coding efficiency, and the flipping device 300 is used to flip the shell 20 that has completed the coding, so that the opening of the shell 20 faces upward, and the tray loading mechanism 400 is used to unload and tray the shell 20, so as to facilitate the transfer of the shell to the next battery processing station, thereby improving the battery assembly efficiency.

[0037] See also Figure 2 , the mirror feeding mechanism 100, the mirror feeding mechanism 100 includes a feeding guide rail 110 and two intermittent feeding units 120, two tracks 111 are arranged on the feeding guide rail 110, the two intermittent feeding units 120 are respectively arranged on the opposite sides of the feeding guide rail 110, and the two intermittent feeding units 120 are arranged opposite to each other; and the two intermittent feeding units 120 are symmetrically arranged with the feeding guide rail 110 as the center, and the two intermittent feeding units 120 operate synchronously, and at the same time, the shell 20 entering the two tracks 111 is pushed toward the engraving machine 200.

[0038] See also Figure 1, wherein two tracks 111 are arranged in parallel, and each track 111 is connected to a vibrator 51 at its starting position, and the shell 20 in the vibration plate 52 is sent into the track 111 through the vibrator 51, and at this time, the bottom surface of the shell 20 in the track 111 is arranged upward.

[0039] See also Figure 3 Each intermittent material shifting unit 120 includes a distance adjusting component 121 and a material shifting member 122. The distance adjusting component 121 is used to drive the multiple housings 20 to separate from each other, and the material shifting member 122 is used to shift the multiple housings 20 to move in a direction close to the coding machine 200 at the same time;

[0040] See also Figure 1 It can be understood that, since the housing is transported by the vibrator 51, the housings 20 in the track 111 are adjacent to each other, and the housing 20 at the rear pushes the housing 20 at the front to move forward along the extension direction of the track 111. In order for the coding machine 200 to ensure the accuracy of coding, it is necessary to ensure that there is a spacing between two adjacent housings 20;

[0041] See also Figure 2 By setting a distance adjustment component 121 to adjust the distance of the shell 20 in the track 111, there is a distance between each shell 20, and the distance between each shell 20 is maintained by the material shifting member 122, and it is dialed into the working range of the coding machine 200, so that a single intermittent material shifting unit 120 can complete the feeding operation of multiple shells 20 in a single pushing action.

[0042] The ends of the two rails 111 are both set toward the flipping device 300, which is used to flip the shell 20. The shell 20 after engraving is in a bottom-up state. The shell 20 is flipped 180° by the flipping device 300 so that the opening of the shell 20 is set upward, so that the battery cell can be installed into the shell 20 in the subsequent workstation.

[0043] See also Figure 1 The loading mechanism 400 is used to load and unload the shells 20 . In order to facilitate the batch transfer of the shells 20 , the shells 20 that have been coded and fermented are loaded into the material tray 60 through the loading mechanism 400 .

[0044] The working principle of the above-mentioned coding device 10 is introduced below:

[0045] The housing 20 to be engraved is placed in two vibration plates 52. When the vibration plates 52 are started, the vibration plates transport the housing 20 to the leveling vibrator 51. At this time, the bottom of the housing 20 faces upward, and the two leveling vibrators 51 transport the housing 20 to the two tracks 111 respectively.

[0046] The housing 20 entering the track 111 is first adjusted in distance by the distance adjusting assembly 121, and then moved to the bottom of the coding machine 200 by the material moving member 122. The feeding action of the housing 20 is completed, and the coding machine 200 engraves the bottom surface of the housing 20.

[0047] In the next feeding action of the shell 20, the newly fed shell 20 pushes the engraved shell 20 toward the flipping device 300 until the shell 20 falls into the flipping device 300, and the flipping device 300 flips the engraved shell 20 so that the opening of the shell 20 faces upward;

[0048] Finally, the housing 20 with the completed coding is loaded onto a tray by the loading mechanism 400, and the operator transfers the tray 60 loaded with the housing 20 to the next processing station.

[0049] See also Figure 2 In one embodiment, the intermittent material dispensing unit 120 also includes a slide plate 123, a longitudinal cylinder 124 and a transverse cylinder 125. The distance adjusting component 121 and the material dispensing member 122 are both installed on the slide plate 123, and the distance adjusting component 121 and the material dispensing member 122 are both arranged toward the track 111. The transverse cylinder 125 is used to push the slide plate 123 to translate in a direction close to or away from the track 111, and the longitudinal cylinder 124 is used to push the slide plate 123 to translate back and forth along the extension direction of the track 111.

[0050] In the initial state, the transverse cylinder 125 and the longitudinal cylinder 124 are both in the retracted state, at which time the slide plate 123 is located at a side away from the engraving machine 200, and at which time the distance adjustment component 121 and the material shifting member 122 are both located outside the track 111 and are not in contact with the housing 20;

[0051] When the intermittent material-dispensing unit 120 is started, the transverse cylinder 125 extends to drive the slide plate 123 close to the track 111, so that the distance-adjusting component 121 and the material-dispensing member 122 are inserted into the track 111. At this time, the distance-adjusting component 121 abuts against the multiple housings 20 in the track 111, and when the distance-adjusting component 121 is started, the abutted housings 20 are separated from each other, and the distance adjustment is completed;

[0052] The longitudinal cylinder 124 extends to push the slide plate 123 to move along the track 111 toward the direction close to the code engraving machine 200. At this time, the multiple housings 20 supported by the distance adjustment component 121 slide toward the direction close to the code engraving machine 200, that is, the housings 20 maintain the distance and move toward the code engraving machine 200 once;

[0053] Subsequently, the transverse cylinder 125 retracts, so that the distance adjustment component 121 is separated from the housing 20 that has completed the distance adjustment, and the distance adjustment component 121 is reset to prepare for the next distance adjustment operation;

[0054] The longitudinal cylinder 124 retracts, so that the distance adjustment assembly 121 returns to the initial position, and the material-moving member 122 on the slide plate 123 is aligned with the housing 20 that has completed the distance adjustment;

[0055] When the horizontal cylinder 125 extends again, the distance adjustment assembly 121 abuts against the multiple housings 20 again, and at the same time, the housing 20 that has moved once is abutted by the material shifting member 122;

[0056] As the longitudinal cylinder 124 extends again, the front group of shells 20 are moved to the bottom of the code engraving machine 200 by the material shifting piece 122 for engraving, and the rear group of shells 20 are adjusted in distance by the distance adjusting component 121 and are pushed into the working range of the code engraving machine 20 by the material shifting piece 122 while waiting for the next feeding action.

[0057] In order to improve the feeding efficiency, two material-pushers 122 are provided, and the two material-pushers 122 are arranged sequentially along the extension direction of the track 111. By increasing the number of material-pushers 122, the stroke of the longitudinal cylinder 124 is reduced, thereby reducing the time for pushing the material, thereby improving the feeding efficiency of the housing 20.

[0058] See also Figure 3 In one embodiment, the material-pickup member 122 includes a positioning block 122a and a paddle 122b, the paddle 122b is disposed on the top of the positioning block 122a, and a wave-shaped material-pickup portion 30 is disposed on the side of the paddle 122b close to the track 111. Each recessed position on the material-pickup portion 30 is a position abutting against the housing 20, and the distance between two adjacent recessed positions is the distance between the housings 20 after the distance adjustment. The paddle 122b can be replaced according to the size of the housing 20 and the requirements of the code engraving to meet the material-pickup requirements, thereby improving the universality of the device.

[0059] See also Figure 2 and Figure 3 In one embodiment, the distance adjustment component 121 includes a splitting cylinder 121a, a base 121b, a plurality of abutting sliders 121c and a plurality of limiting connecting rods 121d. The plurality of abutting sliders 121c are all arranged on the base 121b, and a limiting connecting rod 121d is arranged between each two adjacent abutting sliders 121c. The splitting cylinder 121a is used to drive the plurality of abutting sliders 121c to move closer to or farther from each other, and each abutting slider 121c is used to clamp a housing 20. Before the distance adjustment component 121 works, the plurality of abutting sliders 121c are close to each other. When the distance is adjusted, the splitting cylinder 121a extends, so that the plurality of abutting sliders 121c move away from each other, and drives each housing 20 abutted by the abutting sliders 121c to move away from each other. The farthest distance between two adjacent abutting sliders 121c is limited by the limiting connecting rod 121d.

[0060] See also Figure 6Furthermore, each abutting slider 121c is provided with a limiting groove 41 and a mounting position 42. In two adjacent abutting sliders 121c, the first end of the limiting link 121d is disposed on the mounting position 42 of one of the abutting sliders 121c, and the second end of the limiting link 121d is accommodated in the limiting groove 41 of the other abutting slider 121c. When the second end of the limiting link 121d abuts against the inner wall of the limiting groove 41, the two adjacent abutting sliders 121c cannot move further away from each other, thereby limiting the maximum distance between the two abutting sliders 121c.

[0061] In order to prevent the shell 20 from separating from the abutting slider 121 c during the distance adjustment process, a contoured abutting piece 43 is provided on one side of the abutting slider 121 c close to the track 111 . The contoured abutting piece 43 is used to abut against the outer wall of the shell 20 .

[0062] See also Figure 2 In one embodiment, the mirror feeding mechanism 100 further includes a dust suction nozzle 130, which is located directly below the code engraving machine 200 and has two suction ports 131, which are respectively disposed toward the two tracks 111. The dust generated during the code engraving process is sucked away by the dust suction nozzle 130 to avoid polluting the workshop environment.

[0063] See also Figure 1 In order to improve the turning efficiency, the turning device 300 includes a material receiving slide 310, a turning vibration plate 320 and a material unloading conveying member 330. The ends of the two feeding guide rails 110 are both arranged toward the material receiving slide 310. The material receiving slide 310 is used to turn over the shell 20, and the material unloading conveying member 330 is used to drive the shell 20 to move from the turning vibration plate 320 to the loading mechanism 400.

[0064] A battery comprises a battery cell and a shell 20. The shell 20 is coded by using any of the above-mentioned coding devices, thereby improving the coding efficiency of the battery and preparing for the next processing of the battery, thereby improving the processing efficiency of the battery.

[0065] Compared with the prior art, the present invention has at least the following advantages:

[0066] 1. The two intermittent material-dispensing units 120 simultaneously push the housing 20 to move in the two tracks 111, thereby increasing the feeding speed of the housing 20 and increasing the number of housings 20 entering the working range of the coding machine 200 per unit time, so as to improve the coding speed of the housing 20;

[0067] 2. The turning device 300 and the tray loading mechanism 400 turn over the engraved shell 20 and load it onto a tray, in preparation for the battery assembly operation.

[0068] See also Figure 4In one embodiment, the tray loading mechanism 400 includes: a silo 410, a conveyor belt 420, a stacking assembly 430, an empty tray feeding robot 440, a switch 450 and a tray loading robot 460. The silo 410 separates the loading and unloading positions of the tray 60 and the battery loading position, and drives the tray 60 to sequentially transfer to various working positions in the silo 410 through the conveyor belt 420, the empty tray feeding robot 440 and the switch 450, and then the stacking assembly 430 stacks the full trays 60 into stacks.

[0069] See also Figure 4 The material bin 410 includes a feeding bin 411, a tray stacking bin 412 and a tray loading workbench 413. The tray loading workbench 413 is provided with a transfer bin 413a and a tray loading bin 413b. The feeding bin 411 is arranged adjacent to the transfer bin 413a, and the tray stacking bin 412 is arranged adjacent to the tray loading bin 413b. The feeding bin 411 is used to store empty trays 60. The feeding bin 411 is the feeding position of the empty trays 60, the tray stacking bin 412 is the unloading and stacking position of the trays 60, and the tray loading bin 413b is the position for loading the battery. The transfer bin 413a is used to accommodate the spare trays 60. When the trays 60 in the tray loading bin 413b are removed, the spare trays 60 are switched to the tray loading bin 413b for loading through the switch 450.

[0070] The stacking assembly 430 is disposed in the tray stacking bin 412 and is used to stack the trays 60 . The trays 60 filled with batteries are stacked together in sequence in the tray stacking bin 412 through the stacking assembly 430 , so that the operator can transfer the trays 60 in batches.

[0071] The empty tray feeding robot 440 is used to drive the empty trays 60 to enter the transfer bin 413a one by one, and the empty tray feeding robot 440 only takes out the top empty tray 60 each time and puts the empty tray 60 into the transfer bin 413a for standby use.

[0072] The switch 450 is used to drive the empty tray 60 from the transfer bin 413a to the tray loading bin 413b. The switch 450 can move back and forth between the transfer bin 413a and the tray loading bin 413b, and push the tray in the transfer bin 413a into the tray loading bin 413b during the displacement.

[0073] The conveyor belt 420 is located between the tray loading bin 413 b and the tray stacking bin 412 , and the conveyor belt 420 conveys the full tray 60 from the tray loading bin 413 b into the tray stacking bin 412 .

[0074] The working principle of the above-mentioned tray loading mechanism 400 is introduced below:

[0075] The operator deposits the stacked empty trays 60 into the silo 411;

[0076] The empty tray feeding robot 440 picks up an empty tray 60 located at the top, and puts the empty tray 60 into the transfer bin 413a. The switch 450 starts and pushes the empty tray 60 into the loading bin 413b. The loading robot 460 stacks the batteries into the empty tray 60, and the loading robot 460 loads the empty tray 60.

[0077] After the loading is completed, the conveyor belt 420 drives the full tray 60 to leave the loading bin 413b, and the switch 450 is started again to push the next empty tray 60 into the loading bin 413b for the loading robot 460 to continue loading, and the full tray 60 is sent into the tray stacking bin 412;

[0078] The stacking assembly 430 stacks the trays 60 entering the tray stacking bin 412 in sequence, so that the trays 60 are stacked again in the tray stacking bin 412 to provide batch transfer for the operator.

[0079] See also Figure 4 and Figure 5 In one embodiment, the material bin 410 further includes a lifting support plate 414 and a support member 415. The support member 415 is located at the top of the tray loading bin 413b. The support member 415 is used to support the material tray 60. The lifting support plate 414 is arranged in the tray loading bin 413b. The lifting support plate 414 is used to drive the material tray to move from the top of the tray loading bin 413b to the bottom of the tray loading bin 413b. That is, the support member 415 is used to support the material tray 60 entering the tray loading bin 413b. During the battery tray loading process, the material tray is supported by the support member 415. 60. When the material tray 60 is full and needs to be transferred, the lifting plate 414 rises to hold the material tray 60. At this time, the support member 415 is separated from the material tray 60, and the lifting plate 414 descends with the material tray 60, and finally the material tray 60 is placed on the conveyor belt 420. By adding the lifting plate 414 and the support member 415, the conveyor belt 420 and the loading position of the loading bin 413b can be staggered, so that the action of the conveyor belt 420 transporting the material tray 60 is staggered with the battery loading action, thereby further improving the continuity of the battery loading.

[0080] See also Figure 4 Specifically, the conveyor belt 420 includes a conveyor motor 421 and two synchronous belts 422. The two synchronous belts 422 are arranged in parallel, and a gap is arranged between the two synchronous belts 422. The conveyor motor 421 is used to drive the two synchronous belts 422 to operate synchronously, and the lifting support plate 414 is located between the two synchronous belts 422. Thus, an avoidance space is formed between the two synchronous belts 422 for the lifting support plate 414 to move up and down, thereby improving space utilization.

[0081] See also Figure 4 and Figure 5Further, the support member 415 includes two baffles 415a and two push cylinders 415b. The two push cylinders 415b are arranged on the outer wall of the tray loading bin 413b, and the two push cylinders 415b are arranged facing each other. The two baffles 415a are respectively arranged on the output ends of the two push cylinders 415b. The two push cylinders 415b are used to push the two baffles 415a into or away from the tray loading bin 413b at the same time. Each baffle 415a is used to abut against the bottom of the tray 60. Before the empty tray 60 enters the tray loading bin 413b, the two push cylinders 415b are started, so that the two baffles 415a extend into the tray loading bin 413b. When the empty tray 60 enters the tray loading bin 413b, the two baffles 415a provide support for the bottom of the empty tray 60. When the material tray 60 is full and needs to be switched, the lifting support plate 414 rises to support the material tray 60, and the pushing cylinder 415b drives the blocking piece 415a to retract. At this time, the two blocking pieces 415a are separated from the material tray 60, and the material tray 60 is transferred to the lifting support plate 414. When the lifting support plate 414 is lowered, the blocking piece 415a is extended into the tray loading bin 413b again to prepare to support the next material tray 60.

[0082] See also Figure 4 In order to improve the stacking efficiency, the stacking assembly 430 includes a lifting member 431 and two lifting plates 432. The lifting member 431 is located between the two synchronous belts 422. The lifting member 431 is used to push the material tray 60 away from the synchronous belt 422. The two lifting plates 432 are both located above the synchronous belt 422 and are used to support the material tray 60. The lifting plates 432 are hinged to the material tray stacking bin 412. The lifting member 431 is in the tray stacking bin 412. When the tray 60 moves with the synchronous belt 422 to the top of the lifting member 431, the lifting member 431 lifts the tray 60, so that the tray 60 is separated from the synchronous belt 422. During the rising process of the tray 60, a thrust is applied to the two lifting plates 432. At this time, the two lifting plates 432 flip in the direction away from the center of the tray stacking bin 412. After the tray 60 passes the lifting plates 432, the two lifting plates 432 reverse and return to the initial state due to the loss of thrust support. At this time, the lifting member 431 descends, and the bottom of the tray 60 contacts the lifting plates 432, and the lifting plates 432 provide support for the tray 60.

[0083] When the lifting member 431 lifts up the next material tray 60, the next material tray 60 will also apply thrust to the two lifting plates 432 and flip it over. At the same time, the bottom of the material tray 60 supported by the lifting plates 432 contacts the top of the next material tray 60, and the two are stacked together. After the lifting member 431 is reset, the bottom of the next material tray 60 contacts the lifting plates 432, and so on, so that each material tray 60 is stacked together in sequence on the lifting plates 432.

[0084] In order to prevent the tray 60 from tipping over during the stacking process, the tray stacking bin 412 is provided with four limiting bars 412a, and the four limiting bars 412a are used to fit with the outer wall of the tray 60. The limiting bars 412a provide guidance.

[0085] See also Figure 4 and Figure 5 In one embodiment, the material bin 410 further includes a full tray detector 416, which is disposed on one of the limit bars 412a. The full tray detector 416 is used to detect the height of the material tray 60 above the lifting plate 432, and then determine whether the stacking quantity of the material tray 60 reaches the unloading standard. For example, the full tray detector 416 is a reflective sensor. When the stacking height of the material tray 60 reaches the installation position of the full tray detector 416, the material tray 60 at the top triggers the full tray detector 416. At this time, the material tray stacking bin 412 is full, prompting the operator to perform the unloading operation.

[0086] See also Figure 4 and Figure 5 In one embodiment, the switch 450 includes a rodless cylinder 451, a beam 452 and a tray push block 453. The tray push block 453 is arranged on the beam 452. The rodless cylinder 451 is used to drive the beam 452 to move back and forth between the transfer bin 413a and the loading bin 413b. The tray push block 453 is used to abut against the outer wall of the tray 60.

[0087] A battery adopts any one of the above-mentioned tray loading mechanisms 400 to assist in tray loading and unloading.

[0088] Compared with the prior art, the present invention has at least the following advantages:

[0089] 1. By setting up a material feeding bin 411, a material tray stacking bin 412 and a tray loading workbench 413, the loading / unloading of the material tray and the battery tray loading station are separated, so that the battery tray loading operation is not affected during the material tray loading or unloading operation, so that the battery tray loading operation is continuous, and the battery unloading and loading efficiency is improved;

[0090] 2. The empty tray feeding robot 440, the switch 450 and the conveyor belt 420 drive the trays to transfer between the feeding bin 411, the tray stacking bin 412 and the tray loading workbench 413, and make the feeding bin 411, the tray stacking bin 412 and the tray loading workbench 413 more compact.

[0091] See also Figure 2In one embodiment, in order to improve the accuracy of code engraving, the code engraving device 10 further includes a height adjustment frame 500, which is arranged adjacent to the mirror feeding mechanism 100. The height adjustment frame 500 includes a height adjustment screw rod 510, a movable platform 520 and two support columns 530. The two support columns 530 are arranged at intervals, and the two support columns 530 are both provided with the movable platform 520. The tops of the two support columns 530 are connected by a connecting plate 540. The height adjustment screw rod 510 is arranged at The connecting plate 540 is screwed with the height-adjusting screw 510 and the movable platform 520. Rotating the height-adjusting screw 510 can drive the movable platform 520 to rise or fall along the extension direction of the axis of the support column 530. The engraving machine 200 is installed on the movable platform 520, and the engraving machine 200 is set toward the track 111. By rotating the height-adjusting screw 510, the engraving machine 200 can be moved closer to or away from the track 111, thereby adjusting the distance between the engraving machine 200 and the shell 20, which is convenient for the operator to debug.

[0092] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
