Description

Technical Field

[0001] This invention relates to the field of lithium battery manufacturing technology, specifically to a rotary barcode scanning device for new energy cylindrical lithium batteries. Background Technology

[0002] The new energy industry is developing rapidly, and new energy batteries are an important part of the new energy industry. Various types of new energy batteries are constantly emerging. Among them, the all-tab cylindrical technology has obvious advantages in performance, cost, and safety. It can push the optimal balance between energy density, cost, and safety to a new position. While ensuring the safety of the entire battery pack, it can increase the size of individual cells, improve space utilization, and increase the driving range of the whole vehicle. While ensuring energy density, the all-tab technology optimizes the cylindrical cell structure design, significantly reduces impedance, and the fast charging performance can be three times better than that of conventional single-tab cells.

[0003] During the production of cylindrical batteries, in order to record and match their production information, codes are usually printed on the outer wall of the battery. When it is necessary to find and track the battery, the battery identification information contained in the barcode can be read by a barcode scanner. Barcode information is often used to bind the battery, and barcodes are mostly found on the battery cylinder. However, due to the cylindrical characteristics of the battery, scanning some barcodes can easily cause information reading errors. If it is necessary to scan all the barcode information on the cylindrical battery, the cylindrical battery needs to be rotated, which is inefficient.

[0004] However, during the battery production process, the barcodes on the batteries are not always facing the barcode scanner, which brings certain difficulties to the scanning process. In the existing battery scanning process, manual assistance is required to align the barcodes of the batteries with the barcode scanner one by one to complete the scanning operation. This is inefficient and carries the risk of missing barcodes during manual operation.

[0005] Chinese patent application CN110877810A discloses a battery conveying and scanning device and a conveying and scanning method, comprising: a base having a horizontal mounting platform; a battery conveying unit including a drive mechanism as a power source and a linear module; a battery clamping unit including a fixing part and an adjustable battery support mechanism; and a battery scanning unit for scanning a single battery pack in motion; the method includes the following steps: placing a single battery pack on a support assembly.

[0006] The aforementioned barcode scanning device moves the battery via a conveying unit and works with a scanning unit to scan the battery. However, since the battery barcodes are not always facing the scanning unit, manual assistance is required during the movement to rotate the battery or pre-set the battery barcodes to face the scanning unit. This manual assistance affects the scanning efficiency and poses a risk of missing scans. Summary of the Invention

Detailed Implementation

[0020] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1-9As shown, a rotary scanning device for a large cylindrical lithium battery for new energy includes an active rotating component 1 and a passive rotating component 3 arranged opposite to each other, with a scanning component 2 provided between the active rotating component 1 and the passive rotating component 3; the active rotating component 1 includes a first mounting plate 14 and a plurality of active rotating wheels 17 rotatably connected to the first mounting plate 14, with adjacent active rotating wheels 17 used to support the battery; the passive rotating component 3 includes a second mounting plate 34 and a plurality of passive rotating wheels 35 rotatably connected to the second mounting plate 34, with adjacent passive rotating wheels 35 used to support the battery; a first positioning cylinder 4 is mounted on the top of the first mounting plate 14, and a first push block 41 is mounted on the first positioning cylinder 4; a second positioning cylinder 6 is mounted on the top of the second mounting plate 34 opposite to the first positioning cylinder 4, and a second push block 61 is mounted on the second positioning cylinder 6; the first push block 41 and the second push block 61 move relative to each other under the action of the first positioning cylinder 4 and the second positioning cylinder 6.

[0022] The active rotating component 1 and the passive rotating component 3 are arranged opposite each other, and the battery is conveyed between the active rotating component 1 and the passive rotating component 3. Several active rotating wheels 17 and several passive rotating wheels 35 are arranged correspondingly. When the battery is abutted on the adjacent active rotating wheel 17, the battery abuts on the corresponding adjacent passive rotating wheel 35 at the same time. The rotation of the active rotating wheel 17 drives the rotation of the battery, thereby realizing the barcode scanning component 2 corresponding to different positions of the battery. The passive rotating wheel 35 rotates synchronously under the action of the battery rotation, realizing the stable support of the battery.

[0023] The first positioning cylinder 4 and the second positioning cylinder 6 are arranged opposite to each other. By driving the first push block 41 and the second push block 61 to move relative to each other, the two ends of the battery are clamped, thereby positioning the axial position of the battery and ensuring that the position of the battery meets the requirements of the barcode scanning component 2.

[0024] The barcode scanning component 2 has multiple workstations, which can simultaneously scan multiple batteries, thereby improving the overall scanning efficiency.

[0025] The active rotation component 1 includes a first fixed base plate 11 and a first connecting fixed plate 12 fixedly connected to the first fixed base plate 11. A first mounting plate 14 is installed on one side of the first connecting fixed plate 12, and a first reinforcing rib plate 13 is provided at the connection between the first fixed base plate 11 and the first connecting fixed plate 12. The first mounting plate 14 and the first reinforcing rib plate 13 are located on the same side of the first connecting fixed plate 12.

[0026] The first connecting plate 12 is fixedly connected to the first fixed base plate 11 by bolts. The first mounting plate 14 is installed on the first connecting plate 12 by bolts. The first reinforcing rib plate 13 supports both the first fixed base plate 11 and the first connecting plate 12. The first mounting plate 14 is suspended and located above the first reinforcing rib plate 13.

[0027] A number of active rotating wheels 17 are provided with a synchronous belt 19 that drives the active rotating wheels 17 to rotate. A first mounting plate 14 is provided with a synchronous wheel 153 that drives the synchronous belt 19 to drive the synchronous wheel 19. A speed-regulating motor 15 that drives the synchronous wheel 153 to rotate is installed on the synchronous wheel 153.

[0028] Several active rotating wheels 17 are located at the same horizontal height. The synchronous wheel 153 is connected to the output shaft of the speed regulating motor 15. Under the rotation of the synchronous wheel 153, the synchronous belt 19 is driven, thereby driving the synchronous rotation of several active rotating wheels 17. The number of active rotating wheels 17 is set according to actual needs.

[0029] The first mounting plate 14 is provided with a plurality of active rotating shafts 171 corresponding to a plurality of active rotating wheels 17.

The plurality of idler wheels 18 are located below the plurality of active rotating wheels 17, and the synchronous belt 19 is sequentially connected to the plurality of active rotating wheels 17 and the plurality of idler wheels 18 arranged alternately.

[0030] The active rotating wheel 17 and the active rotating shaft 171 rotate synchronously through a key and keyway. The first bearing 172 is embedded in the first mounting plate 14. The first bearing pressure plate 173 is used to limit the position of the first bearing 172 to ensure that the first bearing 172 is always installed in the first mounting plate 14.

[0031] The idler wheel fixed shaft 181 is fixedly connected to the first mounting plate 14 by bolts, and the idler wheel 18 is rotatably connected to the idler wheel fixed shaft 181. The idler wheel 18 is located between the adjacent active rotating wheel 17. Under the action of the idler wheel 18, the transmission speed of the synchronous belt 19 is limited to ensure the slow rotation of the active rotating wheel 17, thereby meeting the scanning requirements of the battery.

[0032] The first mounting plate 14 is provided with a protective cover 16 for covering a number of idler wheels 18 and a number of drive rotating wheels 17. The first mounting plate 14 is also provided with a motor mounting plate 151 for mounting a speed regulating motor 15.

The first connecting and fixing plate 12 is provided with a first limit adjustment block 5 for limiting the drive rotating wheel 17.

[0033] The protective cover 16 is used to protect the idler wheels 18 and the active rotating wheels 17, preventing foreign objects from interfering with the idler wheels 18 and the active rotating wheels 17 and thus affecting the rotational stability of the idler wheels 18 and the active rotating wheels 17. The limit adjustment block 5 is located between the active rotating wheel 17 and the first mounting plate 14, thereby limiting the position of the active rotating wheel 17 and preventing the active rotating wheel 17 from getting close to the first mounting plate 14, thereby causing the active rotating wheel 17 to detach from the battery.

[0034] The passive rotation assembly 3 includes a second fixed base plate 31 and a second connecting fixed plate 32 fixedly connected to the second fixed base plate 31. A second mounting plate 34 is connected to one side of the second connecting fixed plate 32, and a second reinforcing rib plate 33 is provided at the connection between the second fixed base plate 31 and the second connecting fixed plate 32. The second mounting plate 34 and the second reinforcing rib plate 33 are located on the same side of the second connecting fixed plate 32. A plurality of passive rotating wheels 35 are rotatably connected to the second mounting plate 34. A second limiting adjustment block 7 for limiting the passive rotating wheels 35 is provided on the second connecting fixed plate 32.

[0035] The second connecting plate 32 is fixedly connected to the second fixed base plate 31 by bolts. The second mounting plate 34 is installed on the second connecting plate 32 by bolts. The second reinforcing rib plate 33 supports both the second fixed base plate 31 and the second connecting plate 32. The second mounting plate 34 is suspended and located above the second reinforcing rib plate 33.

[0036] The second mounting plate 34 is provided with a plurality of passive rotating shafts 38 corresponding to a plurality of passive rotating wheels 35. A plurality of second bearings 36 corresponding to a plurality of passive rotating shafts 38 are sleeved on the passive rotating shafts 38. The second mounting plate is provided with a second bearing pressure plate 37 for limiting the position of the second bearings 36.

[0037] The passive rotating shaft 38 and the passive rotating wheel 35 rotate synchronously via a key and keyway. The second bearing 36 is embedded in the second mounting plate 34. The second bearing pressure plate 37 is used to limit the position of the second bearing 36 to ensure that the second bearing 36 is always installed in the second mounting plate 34.

[0038] The barcode scanning component 2 is connected to the active rotating component 1. The barcode scanning component 2 includes a base 21 and a support shaft 22 inserted into the base 21. A first pillar positioning clamp 23 is installed on the support shaft 22. A horizontally arranged horizontal shaft 24 is installed on the first pillar positioning clamp 23. Two parallel connecting shafts 26 are installed at both ends of the horizontal shaft 24. A barcode scanner 29 is installed on each of the two connecting shafts 26.

[0039] The horizontal axis 24 is provided with a second support positioning clamp 25 connected to the connecting shaft 26, and the connecting shaft 26 is provided with a positioning clamp block 27, on which a clamping plate 28 for mounting the barcode scanner 29 is installed.

[0040] Two barcode scanners 29 on the two connecting shafts 26 are located between the active rotating component 1 and the passive rotating component 3, and the two barcode scanners 29 are arranged along the arrangement direction of a number of active rotating wheels 17 and a number of passive rotating wheels 35.

[0041] In actual use, the semi-finished cylindrical batteries are transported to the active rotating component 1 and the passive rotating component 3 via a stepping conveyor line. The semi-finished cylindrical batteries automatically fall onto the active rotating wheel 17 and the passive rotating wheel 35. Under the action of the first positioning cylinder 4 and the second positioning cylinder 6, the first push block 41 and the second push block 61 move relative to each other, thereby positioning the batteries between the active rotating component 1 and the passive rotating component 3. The speed-regulating motor 15 of the active rotating component 1 is activated to make the batteries rotate synchronously with the active rotating wheel 17. During the rotation of the batteries, the barcode scanner 29 performs barcode scanning. After scanning is completed, the batteries are transported to the next station via the stepping conveyor line.
