[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. Unless otherwise clearly specified and defined, the terms "set", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be a communication between the two elements. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0027] like Figure 1-Figure 7As shown, a cutting mechanism for battery cell production includes a frame 1 and a conveyor 2 arranged on the frame 1. A conveyor belt 3 is provided on the conveyor 2. The conveyor 2 is a prior art. The conveyor 2 can drive the conveyor belt 3 to rotate. When the battery cell is transported by the conveyor belt 3 on the conveyor 2, the battery cell can stop at any section on the conveyor belt 3; the cutting mechanism includes a gantry 4 erected above the conveyor 2 and a support unit placed below the conveyor 2. The gantry 4 is provided with a punching unit and a sensing unit capable of detecting the position of the battery cell in real time. The sensing unit is composed of several sensors in the prior art, and the sensor used is a laser displacement sensor , one or more of proximity light sensors, ultrasonic sensors, and Hall position sensors. At the same time, the position information of the battery cell obtained by the sensing unit can be transmitted to the conveyor 2. Through the coordinated work of the sensing unit and the conveyor 2, the battery cell can be accurately stopped at the position where it needs to be cut; a support bar 5 that can be supported on the inner side of the conveyor belt 3 is provided in the conveyor 2; the support unit includes a supporting fork 6 that can be moved to be flush with the support bar 5, and a punching gap is left between the supporting fork 6 and the support bar 5. The punching unit includes several groups of punching knives 7 that can move toward the punching gap, and the end of the punching knife 7 can form a shear force with the side edge of the support bar 5.

[0028] Specifically, the conveyor 2 can convey continuous battery cells through the conveyor belt 3, confirm the position of the battery cell through the sensing unit, and when the position on the battery cell to be cut moves to the position directly below the punching knife 7, the conveyor belt 3 stops running, and the support flat fork 6 can move to a position flush with the support bar 5. At this time, the position below the position on the battery cell to be cut is in a suspended state (that is, the position on the battery cell to be cut is above the punching gap), and the support flat fork 6 and the support bar 5 are close to the two sides of the position to be cut at the bottom of the battery cell. Then, as the punching knife 7 continues to move toward the punching gap, the shear force formed between the punching knife 7 and the support bar 5 can cut the battery cell. The battery cell production cutting mechanism in this technical solution can quickly reset after completing a battery cell cutting operation and wait for the next action. The cutting efficiency is high and can meet large-scale production needs.

[0029] As mentioned above, the supporting flat fork 6 is in the shape of a fork, and is provided with a plurality of flat supporting ends 601 respectively staggered with the punching blades 7 , and each flat supporting end 601 corresponds to one punching blade 7 .

[0030] Furthermore, in order to make the conveyor belt 3 more stable when conveying the battery cells, thereby reducing the error when the punching knife 7 cuts the battery cells, as shown in FIG. Figure 1 、 Figure 2As shown, the conveyor 2 is provided with several groups of support plates 8 that can support the inner side of the conveyor belt 3, and the width of the support plates 8 is greater than the width of the conveyor belt 3. The conveyor belt 3 supported by the support plates 8 can effectively prevent the conveyor belt 3 from being bumpy or offset when conveying battery cells.

[0031] Furthermore, in order to prevent the battery cell from shifting during the cutting process, Figure 5 As shown, a set of fixed pressure plates 9 are suspended on the gantry 4 and arranged opposite to the support plate 8. The fixed pressure plates 9 can press down on the support plate 8 and / or the conveyor belt 3. The fixed pressure plates 9 can contact the battery cells before the punching blades 7 and can press down on the battery cells.

[0032] Furthermore, in order to increase the cutting accuracy of the battery cells, a group of relatively arranged clamps 10 are provided on the gantry 4, and a group of clamps 10 can move synchronously toward the conveyor belt 3. In the present technical solution, a group of clamps 10 can contact the battery cells before the fixed pressure plate 9, so as to correct the position of the battery cells on the conveyor belt 3 before the sensing unit determines the position of the battery cells, thereby enabling the sensing unit to accurately judge the position of the battery cells on the conveyor belt 3 and prevent cutting deviation.

[0033] As mentioned above, a group of splints 10 are arranged on the clamping cylinder 13, and the clamping cylinder 13 can drive a group of splints 10 to move synchronously toward or away from each other. The clamping cylinder 13 is a pneumatic actuator in the prior art, which has high precision and can quickly respond to and accurately execute the movement requirements of the splint 10.

[0034] In the embodiment, the movement of the pressing plate, the supporting fork 6, and the punching blade 7 can all be driven by conventional pneumatic or hydraulic cylinders. Preferably, the pneumatic or hydraulic cylinders used for the pressing plate, the supporting fork 6, and the punching blade 7 are all multi-axis types to prevent the pressing plate, the supporting fork 6, and the punching blade 7 from rotating during movement.

[0035] like Figure 6 As shown, based on the first embodiment, the punching unit further includes a blade holder 11 capable of receiving the punching blade 7. The blade holder 11 is provided with a positioning plate 12 capable of being pressed onto the punching blade 7. The punching blade 7 is provided with a circular through-hole 701. Bolts capable of being threadedly connected to the blade holder 11 are provided through the positioning plate 12 and the punching blade 7. The blade holder 11 can be fixedly mounted at the output end of the air cylinder or oil cylinder. The positioning plate 12 and the blade holder 11 can be quickly disassembled and assembled via bolts, making it easy to replace the punching blade 7.

[0036] Furthermore, in the present technical solution, the punching knife 7 is a chisel-type grinding knife, which can make the blade of the punching knife 7 very sharp, provide excellent cutting performance, and thus increase the cutting efficiency.

[0037] Working principle: The conveyor 2 can convey continuous battery cells through the conveyor belt 3. When the position on the battery cell that needs to be cut moves to just below the punching knife 7, the conveyor belt 3 stops moving, and the supporting flat fork 6 can move to a position flush with the support bar 5. At the same time, the clamping cylinder 13 drives a group of clamps 10 to move synchronously toward each other, so that the clamps 10 are clamped on both sides of the battery cell, and the position of the clamps 10 on the conveyor belt 3 is corrected. Subsequently, the fixed pressure plate 9 is pressed down on the battery cell to fix the position of the battery cell on the conveyor belt 3. The punching knife 7 then moves toward the battery cell until the battery cell is cut. The cutting mechanism for battery cell production in this technical solution can continuously cut continuous battery cells into single battery cells, which can meet large-scale production needs.

[0038] The above description is based on the ideal embodiment of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
