Referring to fig. 1-4, a die attach tab handling apparatus 1 is provided according to one embodiment of the present application. The cell protection sheet taking device 1 is used for separating the protection sheet from the cell and carrying the protection sheet; the battery cell protection sheet taking device comprises a supporting frame 11, a fixing mechanism 12 and a pressing block 13, wherein the fixing mechanism 12 is arranged in the middle of the supporting frame 11, and the fixing mechanism 12 is used for fixing the protection sheet;
At least two pressing blocks 13 are arranged, at least two pressing blocks 13 are mounted on the supporting frame 11, and at least two pressing blocks 13 are symmetrically arranged relative to the fixing mechanism 12; the pressing block 13 is used for abutting the protection sheet and applying pressure to the protection sheet.
In the device for taking the battery cell protection sheet provided by the embodiment of the application, a fixing mechanism 12 and a pressing block 13 are arranged on a supporting frame 11; wherein the supporting frame 11 is used for providing the installation and supporting functions for the fixing mechanism 12 and the pressing block 13.
As shown in fig. 2, a protective sheet 02 is connected to both sides of the battery cell 01 in the thickness direction thereof. During operation of the cell protection sheet handling device 1, it is disposed opposite the protection sheet 02 and above the protection sheet 02. When the protection sheet 02 is taken, the battery cell protection sheet taking device 1 moves downwards, at least two pressing blocks 13 are abutted against the protection sheet and apply a downward pressure F to the protection sheet, so that the protection sheet is slowly deformed, a vacuum region between the protection sheet 02 and the battery cell 01 is broken, the condition that the protection sheet is tightly attached to the surface of the battery cell is improved, and the protection sheet is fixed and carried by using the fixing mechanism 12; the situation that the separation between the protective sheet 02 and the battery cell 01 is difficult to realize and the membrane and the pole piece of the battery cell are folded and damaged is avoided.
After the protective sheet 02 located on the upper side of the cell 01 is removed from the surface of the cell 01, the cell 01 is turned over together with the other protective sheet 02, and the other protective sheet 02 is taken in the same manner as described above.
Referring to fig. 1-3, in one embodiment, the pressing block 13 has a pressing surface 131, where the pressing surface 131 is used to abut against the protection sheet, and the pressing surface 131 is an inner side surface of the pressing block 13; and the pressing surface 131 is gradually inclined toward the outer side along the direction gradually away from the supporting frame 11. For example, the cross section of the pressing block 13 is a right triangle, and the pressing surface 131 is a side corresponding to the hypotenuse of the right triangle.
In this specific example, the pressing block 13 has an obliquely arranged inner side surface as a pressing surface for abutting the protective sheet 02 and applying a pressing force to the protective sheet 02; the inclined inner surface can be brought into linear contact with the protective sheet 02 at the edge position of the protective sheet 02. For example, the pressing block 13 is a wedge block with a right triangle cross section, and the pressing surface 131 is a side corresponding to the hypotenuse of the right triangle.
If the pressing block 13 is set to be rectangular, the bottom surface of the pressing block 13 away from the supporting frame 11 is used as a pressing surface to abut against the protection sheet 02, so that the pressing block 13 and the protection sheet 02 form surface-to-surface contact, and the risk of pressing the battery cell 01 exists. In this embodiment, as described above, the inner side surface of the pressing block 13 that is obliquely disposed can form a linear contact with the protection sheet 02 at the edge position of the protection sheet 02, so as to be capable of tolerating the deviation of the cell position, and ensure that the contact position of the pressing block 13 and the protection sheet 02 is always at the edge of the protection sheet 02, thereby avoiding the cell 01 from being damaged by pressing. In addition, the pressing block 13 forms linear contact with the protection sheet 02 at the edge position of the protection sheet 02, which is more beneficial to breaking the vacuum region between the protection sheet 02 and the battery cell 01, and ensures that the protection sheet 02 and the battery cell 01 can be smoothly separated.
It will be appreciated that the inner side refers to the side closer to the center of the support frame 11, and the outer side refers to the side farther from the center of the support frame 11.
Referring to fig. 1-3, in one embodiment, the cross section of the supporting frame 11 is rectangular, the number of the pressing blocks 13 is four, and the four pressing blocks 13 are respectively corresponding to the four top corners of the supporting frame 11.
In this specific example, one pressing block 13 is respectively disposed at four vertex angle positions of the supporting frame 11 with a rectangular cross section, and the cross section of the protection sheet 02 is also generally rectangular, so that the four pressing blocks 13 apply a pressing force to the protection sheet 02 at the four vertex angle positions of the protection sheet 02, which is more beneficial to breaking the vacuum area between the protection sheet 02 and the battery cell 01, and ensures that the protection sheet 02 and the battery cell 01 can be smoothly separated.
Referring to fig. 1-2, in one embodiment, the pressing block 13 is detachably connected to the supporting frame 11.
In this specific example, the pressing block 13 is detachably mounted on the supporting frame 11, and if the pressing block 13 is damaged, the pressing block 13 can be conveniently replaced.
Referring to fig. 1-4, in one embodiment, the supporting frame 11 is provided with a positioning hole 110, the pressing block 13 is connected with a positioning screw 14, and the pressing block 13 is detachably connected with the supporting frame 11 at the positioning hole 110 through the positioning screw 14.
In this specific example, the pressing block 13 and the supporting frame 11 are detachably connected by driving the positioning screws 14 into the positioning holes 110, so that the installation and the removal of the pressing block 13 on the supporting frame 11 are easy to operate.
Referring to fig. 4, in one embodiment, the positioning hole 110 is a waist-shaped positioning hole 110.
In this specific example, the positioning hole 110 formed on the supporting frame 11 is set as the waist-shaped positioning hole 110, so that the position of the pressing block 13 can be finely adjusted on the supporting frame 11 according to the actual use requirement, thereby achieving better use effect.
Referring to fig. 1-2, in one embodiment, the support frame 11 is made of steel. In one embodiment, the pressing block 13 is made of plastic steel.
In the specific example, the supporting frame 11 is made of a steel structural member, and the pressing block 13 is made of a plastic steel sectional material; thus, the support frame 11 and the pressing block 13 are firm and durable, and the connection reliability of the support frame 11 and the pressing block 13 can be ensured.
Referring to fig. 1-2, in one embodiment, the securing mechanism 12 is a suction cup mechanism.
In this specific example, the protective sheet 02 is sucked by a suction cup mechanism, which is easy to control and can fix and convey the protective sheet relatively reliably.
