Description

Technical Field

[0001] The utility model relates to the technical field of tab cutting, in particular to a high-precision middle splitting cutting device for tab glue with multiple tab strips. Background Technique

[0002] Traditional tab glue slitting equipment is generally of the type of upper punching on the knife line, upper and lower die punching, and equidistant movement cutting of the cutting knife. In the tab manufacturing process, the rubber strip is first pre-pasted on the upper and lower surfaces of the metal strip, and after high-frequency heating and pressing, the rubber strip is bonded to the metal strip. Generally, one rubber strip is bonded at the same horizontal position of multiple metal strips, and the rubber strip is slit by the slitting equipment.

[0003] The utility model with the publication number of CN219755495U is named a tab glue slitting device, which includes a slitting mechanism, a servo drive mechanism, a base and a tab tensioning mechanism. The tab tensioning mechanism is arranged at one end of the base, and both ends of the tab tensioning mechanism are used to fix both ends of the strip-shaped tab. The slitting mechanism includes a slitting shaft rod part and a shaft rod drive part. The lower slitting knife and the upper slitting knife both rotate between both ends of the tab tensioning mechanism through the shaft rod drive part respectively. The first shaft rod and the second shaft rod can move horizontally between both ends of the tab tensioning mechanism along the axial direction of the linear slide table. By controlling the lower slitting knife and the upper slitting knife to move horizontally between both ends of the tab tensioning mechanism through the servo drive mechanism, the purpose of slitting multiple tab glues is achieved. The distance that the lower slitting knife and the upper slitting knife move each time can be adjusted according to the width dimension of the tab strip, so that the tab glue slitting device can be adapted to tab strips with different width dimensions for slitting tab glue.

[0004] However, it cannot achieve the effect of middle splitting cutting of tabs with different thicknesses and all tab glues, and cannot perform middle splitting cutting. The tab glue between two adjacent tabs may have deviations due to die deviations or uneven shrinkage of the tab glue caused by high-frequency and hot pressing forming, and strict middle splitting cutting cannot be carried out, resulting in large splitting deviations and unable to ensure the splitting accuracy. The more the number of formed tabs, the lower the splitting accuracy. The tabs with attached tab glue are used in the battery, causing swelling and liquid leakage, which greatly affects the sealing performance of the tab glue and the electrical conductivity of the metal strip.

The pressing driving device is set as a lifting air cylinder, and the output shaft of the lifting air cylinder is arranged vertically downward, and the end of the output shaft is vertically connected to the pressing block.

[0038] A pressing block 302 is provided below the pressing driving device 301, and a clamping block 303 is provided below the pressing block. The surfaces of the pressing block and the clamping block are wrapped with die-cutting Teflon and fixed and pasted with high-temperature tape at the contact surface. On the one hand, during the use of the pressing block and the clamping block, the loss and friction are reduced, and on the other hand, the surfaces of the tab ears and their tab ear adhesives are protected to avoid scratches and damage on the surfaces.

[0039] Before the pressing driving device 301 is started, the output shaft of the lifting air cylinder is in the initial retracted state and is guided by the upstream guiding mechanism 4. After the 6 tab ears pass through the upstream pressing mechanism in parallel and at equal intervals, they are input into the cutting mechanism and then pass through the downstream pressing mechanism 3 and then through the downstream guiding mechanism 4.

The lens of the CCD camera faces downward and is set directly opposite the slitting component. Inside the CCD camera body, there are a camera sensor, a storage chip and a transmission communication interface. The transmission communication interface is connected to the precision centering master control through a communication line.

[0043] Six tab ears are pressed tightly by the upstream material pressing mechanism and the downstream material pressing mechanism and are in a taut state. The CCD measurement device is started. The servo cylinder drives the slider to extend forward along the horizontal slide rail, driving the CCD camera to move away from the servo cylinder side. It stops at the position of the outermost tab ear. After the CCD camera is turned on, the servo cylinder is started again, driving the slider 704 to retract along the horizontal slide rail 702. During the uniform movement, the CCD camera 701 continuously captures and collects image information on the distribution and position of multiple tab ears and tab ear glue, and feeds it back to the precision centering master control for information analysis.
