Description

Technical Field

[0001] The utility model relates to the technical field of arc-shaped battery processing, in particular to an arc-shaped lithium battery post-packaging edge trimming device. Background Art

[0002] Curved batteries are a type of battery with a unique shape. Their curved form allows them to better adapt to specific device space requirements. This design makes them particularly advantageous in devices with strict spatial requirements, such as curved or curved electronic products. Compared to traditional square or cylindrical batteries, curved batteries can more closely fit the contours of the device, achieving more efficient space utilization and opening up new possibilities for product design.

[0003] After packaging, the curved lithium battery needs to be trimmed to obtain a regular curved battery shape. However, when using the existing trimming device, the position of the cutter needs to be adjusted sequentially to achieve battery trimming in the horizontal and vertical directions, which greatly restricts the trimming efficiency. Therefore, in view of the above technical defects of the prior art, a post-packaging trimming device for curved lithium batteries is proposed to solve the above technical problems. Utility Model Content

[0004] The purpose of the present invention is to provide a device for trimming arc-shaped lithium batteries after packaging to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0009] As an improved solution of the present invention: the lifting assembly includes a vertical support assembly installed on the base plate, and a central gear is rotatably installed on the vertical support assembly.

[0011] As an improved solution of the present invention: the longitudinal cutter is provided with an extension groove vertically corresponding to the transverse cutter.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] When the longitudinal cutter provided in the present invention is cutting the side edges of the arc-shaped lithium battery, the transverse cutter is moved vertically upwards through the transmission of the lifting assembly.

DETAILED DESCRIPTION

[0020] The technical solution of the present invention is further described in detail below in conjunction with specific embodiments:

[0021] Example 1

[0022] See also Figure 1-5 A device for trimming arc-shaped lithium batteries after packaging, comprising a base plate 1, a gantry 2 being fixed on the base plate 1, a cylinder 3 being fixed on the top of the gantry 2, a bearing block 4 for supporting the arc-shaped battery being fixed on the base plate 1, a lifting plate 6 being fixed on the free end of the cylinder 3, a pair of longitudinal cutters 7 being slidably mounted on the lifting plate 6, a spacing adjustment component for driving the two longitudinal cutters 7 to move toward or away from each other being mounted on the gantry 2, a pair of vertical rods 14 being fixed on the base plate 1, a lifting component being mounted on each vertical rod 14, a transverse cutter 5 being mounted on the lifting component, a pair of transverse makeshift grooves 23 corresponding vertically to the two transverse cutters 5 being opened on the bearing block 4, and a pair of longitudinal makeshift grooves 19 corresponding vertically to the two longitudinal cutters 7 being opened on the bearing block 4.

[0023] When the device is in use, the arc-shaped lithium battery that needs to be trimmed is placed on the supporting block 4, and the lifting plate 6 is driven vertically downward by the cylinder 3. The lifting plate 6 drives the longitudinal cutter 7 to move vertically downward to realize longitudinal trimming of the arc-shaped lithium battery.

[0024] The spacing adjustment assembly includes a pair of horizontally arranged crossbars 15, onto which the longitudinal cutter 7 is slidably mounted. A wedge 9 is fixed to the longitudinal cutter 7, and a vertical plate 8 is fixed to the inner top of the portal frame 2, aligned with the wedge surface of the wedge 9. A stop collar 20 is fixed to the crossbar 15, which abuts the longitudinal cutter 7. A baffle 16 is fixed to the end of the crossbar 15, and a horizontal spring coil 17 is fixed between the baffle 16 and the longitudinal cutter 7.

[0025] Through the above arrangement, when the longitudinal cutter 7 moves vertically upward, the wedge block 9 moves vertically upward and is pushed by the vertical plate 8. At this time, the two longitudinal cutters 7 move away from each other. At this time, the two longitudinal cutters 7 are not vertically corresponding to the transverse cutter 5. When the transverse cutter 5 moves vertically downward to cut the curved lithium battery, it will not be blocked by the longitudinal cutter 7, thereby ensuring the smooth cutting of the curved lithium battery.

[0026] Example 2

[0027] See also Figure 1-5 In addition to Example 1, the lifting assembly of this device includes a vertical support assembly mounted on the base plate 1. A central gear 11 is rotatably mounted on the vertical support assembly. A vertical rack I10 and a vertical rack II12 are respectively meshed and connected on either side of the central gear 11. The vertical rack I10 is fixed to the transverse cutter 5, and the vertical rack II12 is fixed to the crossbar 15. The vertical support assembly includes a vertical rod 14 vertically fixed to the base plate 1. An L-shaped frame 13 is fixed to the top of the vertical rod 14. The central gear 11 is rotatably mounted on the L-shaped frame 13. An extension plate 22 fixed to the transverse cutter 5 is slidably sleeved on the vertical rod 14. A vertical spring coil 21 is fixed between the extension plate 22 and the L-shaped frame 13.

[0028] Through the above arrangement, when the longitudinal cutter 7 moves vertically upward, the longitudinal cutter 7 drives the cross bar 15 to move vertically upward. At this time, the vertical rack II12 moves vertically upward, the vertical rack II12 drives the center gear 11 to rotate, and the center gear 11 drives the vertical rack I10 to move vertically downward. At this time, the transverse cutter 5 moves vertically downward and performs a transverse trimming operation on the arc-shaped lithium battery.

[0029] Among them, an extension groove 18 is provided on the longitudinal cutter 7, which is vertically corresponding to the transverse cutter 5. The extension groove 18 can effectively prevent the transverse cutter 5 from extending into the extension groove 18 when the transverse cutter 5 and the longitudinal cutter 7 are staggered, thereby ensuring the smooth lifting and lowering of the transverse cutter 5 and the longitudinal cutter 7.

[0030] To sum up, when the longitudinal cutter 7 provided in the present invention is cutting the side edges of the curved lithium battery, the transverse cutter 5 is moved vertically upward through the transmission of the lifting assembly. When the transverse cutter 5 is cutting the transverse edges of the curved lithium battery, the two longitudinal cutters 7 are moved away from each other through the spacing adjustment assembly, thereby avoiding the transverse cutter 5 and ensuring that the transverse cutter 5 will not be hindered by the transverse cutter 5 during its downward movement. The longitudinal and transverse cutting actions of the curved lithium battery are alternately and continuously performed, thereby greatly improving the cutting efficiency of the curved lithium battery.
