DETAILED DESCRIPTION

[0023] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] See also Figures 1 to 6 As shown, the utility model provides a battery pole piece cutting mechanism for hydrogen fuel cell production, comprising a workbench 1, a top plate 2 is installed above the workbench 1, a linear drive 3 is installed on the top of the top plate 2, a movable plate 4 is installed on the working end of the linear drive 3, a cutting tool 5 is provided at the bottom of the movable plate 4, a clamping assembly 6 for fixing and clamping the battery pole piece is also installed on the top of the workbench 1, and a pressing assembly 7 for pressing the battery pole piece is also installed on the workbench 1.

[0025] The battery pole pieces to be cut are placed on the workbench 1 and are firmly fixed by the clamping assembly 6 to prevent displacement during the cutting process and ensure cutting accuracy. The battery pole pieces are pressed by the pressing assembly 7 before cutting to reduce swelling caused by multi-layer hot pressing and ensure the accuracy of cutting size. The linear drive 3 installed on the top plate 2 is started, and the linear drive 3 drives the movable plate 4 to move downward along a preset trajectory. The battery pole pieces are cut by the cutting tool 5 installed at the bottom of the movable plate 4.

[0026] See also Figures 1 to 5 As shown, the clamping assembly 6 includes a fixed plate 61, a first threaded rod 62, a knob 63, a movable seat 64, a rotating seat 65, a connecting rod 66 and a clamping plate 67; two fixed plates 61 are provided and are arranged at the top of the workbench 1; the first threaded rod 62 is threadedly arranged on the fixed plate 61; the knob 63 is arranged at one end of the first threaded rod 62; the movable seat 64 is arranged at the other end of the first threaded rod 62; the rotating seat 65 is installed on one side of the movable seat 64; the connecting rod 66 is rotatably arranged in the rotating seat 65; the clamping plate 67 is installed on the connecting rod 66, and an anti-deviation mechanism is also provided between the clamping plate 67 and the movable seat 64 to prevent the battery electrode from being offset during processing.

[0027] The staff rotates the knob 63 to drive the first threaded rod 62 to rotate on the fixed plate 61, and the rotation of the first threaded rod 62 is converted into axial movement, pushing the movable seat 64 to move toward the battery pole piece, and the movement of the movable seat 64 is transmitted to the clamping plate 67 through the connecting rod 66, so that the clamping plate 67 gradually approaches and contacts the battery pole piece, thereby fixing the battery pole piece to prevent it from shifting during the cutting process and affecting the cutting accuracy. Due to the setting of the anti-shift mechanism, the cutting force during the cutting process is prevented from acting on the battery pole piece, causing the pole piece to undergo a slight local shift or deformation, thereby ensuring the cutting accuracy.

[0028] See also Figures 3 to 5 As shown, the anti-deviating mechanism includes a fine-tuning box 68, a connecting seat 69, a fine-tuning rod 610, a limiting plate 611, a spring 612, a rotating rod 613, a rotating piece 614 and a driving motor 615; the fine-tuning box 68 is installed on one side of the moving seat 64; there are two connecting seats 69 and the connecting seat 69 is arranged on one side of the clamping plate 67; the fine-tuning rod 610 is rotatably arranged on the connecting seat 69, and one end of the fine-tuning rod 610 passes through the moving seat 64 and extends into the fine-tuning box 68; the limiting plate 611 is installed on the fine-tuning rod 610; a spring 612 is sleeved on the fine-tuning rod 610, one end of the spring 612 abuts against the limit plate 611, and the other end of the spring 612 abuts against the inner wall of the fine-tuning box 68; a rotating rod 613 is arranged in the fine-tuning box 68; a rotating piece 614 is arranged on the rotating rod 613; a driving motor 615 is installed on the top of the fine-tuning box 68, one end of the rotating rod 613 is connected to the output end of the driving motor 615, and a warning component for warning the staff of battery electrode offset is provided on the clamping plate 67.

[0029] When the clamping plate 67 fixes both sides of the battery electrode, under normal working conditions, the driving motor 615 remains stationary, the fine-tuning rod 610 maintains a stable position under the action of the spring 612, and the clamping plate 67 firmly clamps the battery electrode. When the battery electrode is offset due to the cutting force, the clamping plate 67 will be driven to offset, and the offset of the clamping plate 67 will drive the fine-tuning rod 610 to move toward the fine-tuning box 68, and contact the rotating piece 614 to rotate along the rotating rod 613, and remind the staff through the warning component. The driving motor 615 is started, the driving motor 615 drives the rotating rod 613, and the rotating rod 613 drives the rotating piece 614 to rotate, and the rotation of the rotating piece 614 drives the fine-tuning rod 610 to move toward the outside of the fine-tuning box 68, thereby adjusting the position of the clamping plate 67 and calibrating the battery electrode, ensuring the processing quality of the battery electrode and improving the cutting accuracy.

[0030] See also Figure 1 and Figure 4 As shown, the warning component includes a first conductive sheet 616 and a second conductive sheet 617; the first conductive sheet 616 is arranged on one side of the clamping plate 67; the second conductive sheet 617 is arranged on the side of the movable seat 64 away from the fine-tuning box 68; a warning light is also provided at the top of the top plate 2, and the first conductive sheet 616 and the second conductive sheet 617 are electrically connected to the warning light respectively.

[0031] When the battery pole piece is offset due to the cutting force, the clamping plate 67 will be offset, and the first conductive piece 616 on one side of the clamping plate 67 will contact the second conductive piece 617 set on one side of the movable seat 64, thereby causing the warning light to light up, reminding the staff that the battery pole piece is offset.

[0032] See also Figure 3 As shown, a limiting slider is provided at the bottom of the movable seat 64, and a limiting slot for the limiting slider to move is provided on the workbench 1.

[0033] When the movable seat 64 is driven to move by the first threaded rod 62 , the movable seat 64 moves on the limiting sliding groove provided on the workbench 1 through the limiting sliding block at the bottom of the movable seat 64 , thereby making the movable seat 64 more stable when moving.

[0034] See also Figure 6 As shown, the pressing assembly 7 includes a rectangular frame 71, a second threaded rod 72, a pressure roller 73 and a turntable 74; the rectangular frame 71 is slidably set on the side walls of the workbench 1; the second threaded rod 72 is threadedly set on the rectangular frame 71; the pressure roller 73 is installed at one end of the second threaded rod 72; and the turntable 74 is installed at the other end of the second threaded rod 72.

[0035] By rotating the turntable 74, the turntable 74 drives the second threaded rod 72 to rotate, and the second threaded rod 72 drives the pressure roller 73 to move downward until the pressure roller 73 contacts the upper end surface of the battery electrode, and by pulling the rectangular frame 71 to move, the pressure roller 73 is driven to move, and the battery electrode is pressed by the pressure roller 73, thereby reducing the swelling phenomenon caused by the multi-layer hot pressing composite and ensuring the accuracy of the cutting size.

While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
