Description

Technical Field

[0001] The present invention relates to the technical field of battery core shell production, and in particular to high-speed automated production equipment for battery core shells. Background Art

[0002] The battery core shell is made by bending an aluminum plate upward to form a hollow rectangular parallelepiped, which is then welded on both sides of the aluminum plate. During the subsequent production process of the battery core shell, the openings at both ends of the battery core shell need to be trimmed according to demand. After trimming, the length and the cuts at both ends of the battery core shell are inspected. If the length and cut shape of the battery core shell do not meet the production standards, it needs to be manually readjusted or scrapped for recycling. In particular, the cut shape often deforms or has burrs, which seriously affects product quality. If quality problems occur in the existing battery core shell during the production process, manual correction is required, which is time-consuming, labor-intensive and inefficient, seriously affecting the production efficiency and production quality of the entire production line.

DETAILED DESCRIPTION

[0035] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. At the same time, the terms "first", "second", etc. are only used to distinguish the names of the components, and have no primary or secondary relationship, and therefore cannot be understood as a limitation on the present invention.

[0037] like Figures 1-16 As shown, the present invention discloses a high-speed automated production equipment for battery core shells: comprising a workbench 1 and a loading mechanism 2, a cutting mechanism 3, a flaring mechanism 4, a size detection mechanism 5, a pressing and shaping mechanism 6 and a stacking and storage mechanism 7 which are sequentially arranged on the workbench 1 along the transmission direction of the battery core shells.

[0038] A conveyor belt 11 is provided on the workbench 1. Support blocks 12 are evenly spaced on the conveyor belt 11. The support blocks 12 have inner grooves extending through their two side walls for accommodating battery core shells. The conveyor belt 11 drives the support blocks 12 through a loading mechanism 2, a cutting mechanism 3, a flaring mechanism 4, a size detection mechanism 5, a pressing and shaping mechanism 6, and a stacking and storage mechanism 7. The loading mechanism 2 separates the stacked battery core shells individually and places them horizontally on their corresponding support blocks 12. The cutting mechanism 3 trims the ends of the battery core shells on the support blocks 12 to meet the required dimensions. The flaring mechanism 4 flares the ends of the cut battery core shells. The size detection mechanism 5 measures the length of the flared battery core shells. The pressing and shaping mechanism 6 photographs the expanded shapes of the battery core shells and presses and shapes them accordingly. The stacking and storage mechanism 7 stacks and stores the pressed and shaped battery core shells.

[0039] like Figure 3As shown, the loading mechanism 2 includes loading supports 21 symmetrically arranged on either side of the conveyor belt 11. A vertically extending loading rack 22 is mounted on each of the loading supports 21. A loading space for stacking and storing battery cell shells is formed between the two loading racks 22. A first extending driver 23 and a second extending driver 24 are spaced apart from each other at the lower ends of the loading racks 22. The output ends of the first and second extending drivers 23 and 24 are connected to a first telescopic block 231 and a second telescopic block 241, respectively. The first and second extending drivers 23 and 24 are used to drive the first and second telescopic blocks 231 and 241, respectively, into and out of the loading space. During loading, the first extending driving member 23 drives the first telescopic block 231 to exit the loading space, and the stacked battery core shells move down to the bottom of the battery core shell at the lower end under the action of gravity and abut against the top of the second telescopic block 241. Then the first extending driving member 23 drives the first telescopic block 231 to extend into the loading space. At this time, the first telescopic block 231 will be inserted into the inner cavity of the second-to-last battery core shell. Then the second extending driving member 24 drives the second telescopic block 241 to exit the loading space. Under the action of gravity, the battery core shell continues to move down to the top of the first telescopic block 231 and abut against the top of the inner cavity of the second-to-last battery core shell. At this time, the penultimate battery core shell is in a suspended state. In the empty state, since the surface of the battery core shell is coated with lubricating oil, the stacked battery core shells will adhere to each other, resulting in the bottom battery core shell being unable to fall by its own gravity. At this time, the second extending driving member 24 drives the second telescopic block 241 to re-extend into the loading space and insert into the inner cavity of the penultimate battery core shell (the lower end surfaces of the first telescopic block 231 and the second telescopic block 241 are inclined, and the distance between the first telescopic block 231 and the second telescopic block 241 is not less than the thickness of the battery core shell). During the insertion of the second telescopic block 241, the penultimate battery core shell will be squeezed downward to separate it from the penultimate battery core shell.

[0040] In order to prevent the battery core shell from colliding and deforming when falling, two first supporting driving members 25 are provided on the loading support 21 below the loading space, and a first support plate 251 is provided on the output end of the first supporting driving member 25.

The first detection mounting seat 513 is driven to slide along the detection slide rail 517; the detection pressure plate 514 is connected to the end surface of the first detection mounting seat 513 facing the second size detection component 52 through the detection elastic member 515, and the displacement sensor 516 is connected to the first detection mounting seat 513, and its detection end is against the end surface of the detection pressure plate 514 away from the second size detection component 52; the detection elastic member 515 includes a guide sleeve 5151, a guide rod 5152 and a detection spring 5153; the guide sleeve 5151 is horizontal Connected to the first detection mounting seat 513, one end of the guide rod 5152 is connected to the detection pressure plate 514, and the other end passes through the guide sleeve 5151 and is connected to a radial limit plate (not shown in the figure). The outer diameter of the radial limit plate is larger than the inner diameter of the guide sleeve 5151; the detection spring 5153 is sleeved on the guide rod 5152, and one end of the detection spring 5153 is against the detection pressure plate 514, and the other end is against the end of the guide sleeve 5151 on the first detection mounting seat 513; the first detection bracket A limit rod 518 is provided on 511, and a limit block 5131 is connected to the bottom of the first detection mounting seat 513. The limit block 5131 is used to abut against the end of the limit rod 518 to limit the output distance of the first detection driver 512; the second size detection component 52 includes a second detection bracket 521 and a reference plate 522 and a second detection driver 523 arranged on the second detection bracket 521. A through hole is provided in the middle of the reference plate 522, and the output end of the second detection driver 523 is connected to a reset push plate.

[0048] When performing size detection, the first detection driver 512 drives the first detection mounting seat 513 to move horizontally toward the reference plate 522, and the detection pressure plate 514 moves with the first detection mounting seat 513. After it abuts against one end of the battery cell shell, it pushes the battery cell shell so that its other end abuts against the reference plate 522. After the displacement sensor 516 detects the compression distance between the first detection mounting seat 513 and the detection pressure plate 514, it compares it with the database (test data of standard parts) to determine whether the size of the battery cell shell is qualified; after the size detection is completed, the second detection driver 523 drives the reset push plate to extend out of the through hole to reset the tested battery cell shell to facilitate subsequent operations.

[0049] like Figure 11-13 As shown, the pressing shaping mechanism 6 includes a pressing detection component 61 and a pressing shaping component 62; the pressing detection component 61 includes a pressing detection support 611 symmetrically arranged on both sides of the conveyor belt 11 and a detection camera 612 arranged on the pressing detection support 611, and the detection camera 612 is used to take a picture of the end of the battery shell after the expansion, and transmit the photographed signal to the control system; the pressing shaping component 62 includes a pressing shaping bracket 621, a pressing shaping driving member 622 and a pressing shaping positioning seat 623; the pressing shaping bracket 621 It is arranged horizontally on the workbench 1, and there are two pressing and shaping positioning seats 623, which are symmetrically arranged on both sides of the conveyor belt 11; the pressing and shaping driving member 622 is arranged on the pressing and shaping bracket 621, and its output end is connected to the pressing and shaping plate 624, and the bottom of the pressing and shaping plate 624 is connected to the position corresponding to the pressing and shaping positioning seat 623 with a pressing and shaping block 625; the pressing and shaping positioning seat 623 is used to support the end of the battery cell shell, and the pressing and shaping driving member 622 is used to drive the pressing and shaping block 625 to press down, thereby pressing and shaping the end of the battery cell shell. Since the height of the pressing and shaping positioning seat 623 is higher than the support seat 12, a horizontal and vertical driving assembly is also provided in the workbench 1, which can lift the battery cell shell on the support seat 12 upward, and then move it horizontally above the pressing and shaping positioning seat 623. Finally, the horizontal and vertical driving assembly drives the battery cell shell down until it falls on the pressing and shaping positioning seat 623; after the pressing and shaping is completed, the horizontal and vertical driving assembly places the battery cell shell back on the support seat 12.

[0050] Both ends of the pressing and shaping plate 624 are provided with connecting grooves 6241 extending along the length direction thereof, and the pressing and shaping block 625 is connected to the corresponding connecting groove 6241 by bolts, so that the user can adjust the position of the pressing and shaping block (625) on the corresponding connecting groove 6241 according to the specific product size; the bottom of the pressing and shaping block 625 is provided with a first curved surface 6251 protruding downward, and the position on the pressing and shaping positioning seat 623 corresponding to the first curved surface 6251 is provided with a second curved surface 6231 protruding upward.

[0051] After the battery cell shell is expanded, there may be bulges at the ends, so its ends need to be pressed and shaped; when pressing and shaping, the detection camera 612 can clearly capture the shape of the openings at both ends of the battery cell shell and transmit the signal to the control system. The control system determines the distance that the pressing and shaping block 625 needs to be pressed down based on the received signal (because the bulge at the end of the battery cell shell will rebound slightly after being flattened, it needs to be pressed down to be slightly concave. The higher the bulge at the end of the battery cell shell, the greater the distance the pressing and shaping block presses down). The first curved surface 6251 at the lower end of the pressing and shaping block 625 will press the bulge at the end of the battery cell shell to a concave state. In this way, after the pressing and shaping block 625 is reset, the concave positions at both ends of the battery cell shell will rebound slightly, thereby making the ends of the battery cell shell smoother.

[0052] like Figure 14 and Figure 15 As shown, the stacking and storage mechanism 7 includes two storage supports 71 symmetrically arranged on both sides of the conveyor belt 11 and a storage trough plate 72 arranged on the storage supports 71.

[0053] A second supporting drive member 75 is provided on the storage support 71 at a position below the storage space, and a second supporting plate 751 is connected to the output end of the second supporting drive member 75. The second supporting drive member 75 is used to drive the second supporting plate 751 to move upward and lift the corresponding battery core shell upward. The battery core shell pushes the supporting portion 731 of the anti-fall block 73, causing the supporting portion 731 to flip over and enter the limiting groove 721. When the battery core shell is lifted upward to above the anti-fall block 73, under the action of the gravity of the counterweight block 733, the supporting portion 731 flips over to the storage space, and the upper surface of the supporting portion 731 is horizontal. At this time, the positioning portion 732 is against the positioning protrusion 74; finally, the second supporting drive member 75 drives the second supporting plate 751 to reset downward, so that the battery core shell falls on the supporting portion 731.

[0054] like Figure 16As shown, the workbench 1 is also equipped with a laser marking mechanism 8. The laser marking mechanism 8 includes a laser marking machine 81 and a second alignment assembly 82.

The second alignment assembly 82 includes two alignment supports 821 symmetrically arranged on either side of the conveyor belt 11. The alignment supports 821 are connected to second alignment drivers 822. The output end of the second alignment driver 822 is connected to a second alignment push plate. Two vertical drivers 823 are also located between the two alignment supports 821. The two vertical drivers 823 are used to lift the battery core shells on the corresponding support 12 to the second alignment workstation. The two second alignment drivers 822 are used to drive the two second alignment push plates to move toward each other, so that the battery core shells at the second alignment workstation are centered. All of the above drivers are cylinders, and can also be linear motors.

[0055] A high-speed automated production equipment for battery core shells of the present invention automatically loads materials onto a support seat 12 through a loading mechanism 2, and a conveyor belt 11 drives the battery core shells on the support seat 12 to pass through a cutting mechanism 3, an expanding mechanism 4, a size detection mechanism 5, a pressing and shaping mechanism 6 and a stacking and storage mechanism 7 in sequence. After the battery core shells are cut and expanded, size detection and the incisions are pressed and shaped, and finally they are stacked and stored. The entire production process is fully automated, and the battery core shell incisions are pressed and shaped after the expansion process, without the need for manual processing. This is not only efficient but also time-saving and labor-saving, greatly improving the production efficiency and production quality of the overall production line.
