[0002] Lithium battery casing is used to protect lithium batteries and is one of the key materials for producing lithium batteries. Lithium battery casing is usually made of metal sheets through cutting or stamping process to obtain the required size of the original sheet, and then the original sheet is stamped into the shape of the lithium battery casing. However, in the process of feeding the original sheet, it is easy for the original sheets to stick to each other, causing equipment shutdown, which not only affects the production efficiency of the workshop, but also causes material waste. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a lithium battery shell original sheet feeding device, which can ensure the single-piece feeding of the original sheet.

[0005] The lifting plate is located on one side of the substrate in the thickness direction, and the lifting plate is parallel to the substrate, and an avoidance hole is arranged on the lifting plate;

[0006] The grabbing assembly comprises a suction cup and a connecting rod, wherein the suction cup is arranged at one end of the connecting rod, and the end of the connecting rod away from the suction cup passes through the avoidance hole and is connected to the base plate, and the diameter of the connecting rod is smaller than the aperture of the avoidance hole.

[0007] Furthermore, the elastic member includes a bolt and a first spring; the screw of the bolt passes through the base plate and is threadedly connected to the lifting plate, the first spring is sleeved on the screw of the bolt, and one end of the first spring rests on the lifting plate, and the end of the first spring away from the lifting plate rests on the base plate.

[0008] Furthermore, the elastic member also includes a second spring, which is sleeved on the screw rod of the bolt, one end of the second spring abuts against the base plate, and one end of the second spring away from the base plate abuts against the nut of the bolt.

[0009] Furthermore, a spacing of at least 0.5 mm is left between the inner wall of the avoidance hole and the shaft of the connecting rod.

[0010] Furthermore, the avoidance hole is a long hole, and a spacing of at least 0.5 mm is left between the inner wall of the avoidance hole in the width direction and the connecting rod body.

[0011] Furthermore, the vibration direction of the vibrator is the thickness direction of the substrate.

[0012] Furthermore, the vibrator is a turbine-type pneumatic vibrator.

[0013] The beneficial effect of the utility model is that: since the substrate of the vibration assembly is respectively connected to the lifting plate and the grabbing assembly, after the lifting plate is connected to the lifting device, the lifting device can drive the substrate and the grabbing assembly to move through the lifting plate. In the process of grabbing the original sheet, after the grabbing assembly absorbs the original sheet through the suction cup, the substrate is vibrated by the vibrator, and the substrate transmits force to the suction cup through the connecting rod, causing the suction cup to vibrate, thereby shaking off the excess original sheet, and the aperture of the avoidance hole on the lifting plate is larger than the diameter of the connecting rod, so the connecting rod can avoid transmitting force to the lifting plate during the vibration process. At the same time, since the substrate is connected to the lifting plate through an elastic member, when the substrate vibrates, the elastic member is used to absorb the vibration to reduce the impact of the vibrator operation on the lifting plate, thereby ensuring the connection reliability between the lifting plate and the lifting device.

[0021] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0022] Please refer to Figures 1 to 3As shown, the utility model is a lithium battery shell raw sheet feeding device, comprising a vibration component 1, a lifting plate 2 and a grabbing component 3; the vibration component 1 comprises a substrate 11, a vibrator 12 and an elastic member 13, the vibrator 12 is arranged on the substrate 11, and the substrate 11 is connected to the lifting plate 2 through the elastic member 13;

[0023] The lifting plate 2 is located on one side of the substrate 11 in the thickness direction, and the lifting plate 2 is parallel to the substrate 11, and a avoidance hole 21 is provided on the lifting plate 2;

[0024] The gripping assembly 3 includes a suction cup 31 and a connecting rod 32 . The suction cup 31 is disposed at one end of the connecting rod 32 . The end of the connecting rod 32 away from the suction cup 31 passes through the avoidance hole 21 and is connected to the substrate 11 . The diameter of the connecting rod 32 is smaller than the aperture of the avoidance hole 21 .

[0025] Working principle: Since the base plate 11 of the vibration component 1 is connected to the lifting plate 2 and the grabbing component 3 respectively, after the lifting plate 2 is connected to the lifting device, the lifting device can drive the base plate 11 and the grabbing component 3 to move through the lifting plate 2.

[0026] In the process of grabbing the original sheet, after the grabbing assembly 3 absorbs the original sheet through the suction cup 31, the vibrator 12 is used to vibrate the substrate 11, and the substrate 11 transmits the force to the suction cup 31 through the connecting rod 32, so that the suction cup 31 vibrates, thereby shaking off the excess original sheet, and the diameter of the avoidance hole 21 on the lifting plate 2 is larger than the diameter of the connecting rod 32, so the connecting rod 32 can avoid transmitting the force to the lifting plate 2 during the vibration process. At the same time, since the substrate 11 is connected to the lifting plate 2 through the elastic member 13, when the substrate 11 vibrates, the elastic member 13 is used to absorb the vibration to reduce the influence of the vibrator 12 operation on the lifting plate 2, thereby ensuring the connection reliability between the lifting plate 2 and the lifting device.

[0027] In one embodiment, see Figure 1 and Figure 2 As shown, the elastic member 13 includes a bolt 131 and a first spring 132; the screw of the bolt 131 passes through the base plate 11 and is threadedly connected to the lifting plate 2, the first spring 132 is sleeved on the screw of the bolt 131, and one end of the first spring 132 abuts against the lifting plate 2, and the end of the first spring 132 away from the lifting plate 2 abuts against the base plate 11. The base plate 11 and the lifting plate 2 are connected together by the bolt 131, and the first spring 132 is used to absorb the vibration of the base plate 11.

[0028] In an optional implementation, please refer to Figure 1 and Figure 2As shown, the elastic member 13 also includes a second spring 133, which is sleeved on the screw of the bolt 131, one end of the second spring 133 abuts on the substrate 11, and the end of the second spring 133 away from the substrate 11 abuts on the nut of the bolt 131. In the process of grabbing the original sheet, when the suction cup 31 contacts the original sheet, the grabbing assembly 3 cannot continue to approach the original sheet with the lifting plate 2, thereby compressing the second spring 133. At this time, the elastic force of the second spring 133 can drive the suction cup 31 to further contact the original sheet, thereby ensuring the suction effect of the suction cup 31 on the original sheet. After grabbing the original sheet, the second spring 133 can ensure that the substrate 11 is reset.

[0029] In an optional implementation, please refer to Figure 3 As shown, a spacing B is left between the inner wall of the avoidance hole 21 and the rod body of the connecting rod 32, and the spacing B is at least 0.5 mm. The minimum spacing of 0.5 mm can ensure that the connecting rod 32 will not contact the lifting plate 2 when vibrating.

[0030] In an optional implementation, please refer to Figure 3 As shown, the avoidance hole 21 is a long hole, and a spacing B is left between the inner wall of the avoidance hole 21 in the width direction and the rod body of the connecting rod 32, and the spacing B is at least 0.5 mm.

[0031] In an optional embodiment, the vibration direction of the vibrator 12 is the thickness direction of the substrate 11. Limiting the vibration direction of the vibrator 12 to the thickness direction of the substrate 11 can not only meet the requirements of single-piece loading, but also reduce the collision between the connecting rod 32 and the lifting plate 2 due to lateral movement.

[0032] In an optional embodiment, the vibrator 12 is a turbine-type pneumatic vibrator. The vibration frequency of the turbine-type pneumatic vibrator is 40,000 to 41,000 times per minute at an operating pressure of 0.2 MPa, 60,000 to 61,000 times per minute at an operating pressure of 0.4 MPa, and 78,000 to 79,000 times per minute at an operating pressure of 0.6 MPa.

[0033] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
