[0002] In battery production, one of the processes requires grinding a large number of battery cell electrodes. The existing grinding method is mainly based on manual sandpaper grinding, which is inefficient and consumes a lot of manpower costs. Therefore, it is imperative to develop equipment that can fully automate the grinding of battery cell electrodes. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a battery cell electrode grinding device, which can realize full-automatic grinding of the cell electrode.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A battery cell electrode grinding device, comprising:

[0006] A feeding mechanism, comprising an inclined slide and a first pressing device, wherein a movable gear lever is provided at the end of the inclined slide, and the first pressing device is used to press the second piece and above of materials;

[0007] The conveying and clamping mechanism comprises a conveyor belt, the conveyor belt is located below the end of the inclined slideway, a sensor and a material pushing device are sequentially arranged on one side of the conveyor belt, and a second material pressing device is arranged above the other side;

[0008] The grinding mechanism is located on the other side of the conveyor belt and includes a lifting platform. The lifting platform is provided with a first platform, the first platform can move forward and backward, the first platform is provided with a second platform, the second platform can move left and right, and the second platform is provided with a grinding tool.

[0009] The battery cell electrode grinding device according to the embodiment of the present invention has at least the following beneficial effects:

[0010] 1. The feeding mechanism adopts an inclined design. Under the action of gravity, the continuous addition of battery cells can be achieved through the sequence of the gear lever and the first pressing device, reducing the number of personnel required to operate the equipment.

[0011] 2. The conveying clamping mechanism uses the pushing device to push the battery cell to the edge of the conveyor belt and clamps it through the second pressing device to complete the positioning of the battery cell.

[0012] 3. The grinding mechanism is equipped with a lifting platform and two platforms for forward and backward movement and left and right movement, so that the grinding tool can be flexibly adjusted in the three directions of up and down, left and right, and front and back, so as to achieve the purpose of simulating repeated manual grinding actions, reduce the loss of grinding tools, and reduce the cost of use.

[0013] According to some embodiments of the present invention, the first pressing device is located on one side of the inclined slide, and a baffle is provided on the other side of the inclined slide to press the battery cell in the horizontal direction.

[0014] According to some embodiments of the present invention, a first cylinder is horizontally disposed at the rear end of the inclined slide, and a push rod of the first cylinder is connected to the lever through a vertical fixing plate. The push rod drives the lever to move horizontally, thereby opening the terminal outlet of the inclined slide. The first cylinder is disposed at the rear end of the inclined slide to save space.

[0015] According to some embodiments of the present invention, a first positioning baffle plate capable of blocking the material is provided along the direction of movement of the conveyor belt, and the first positioning baffle plate is located on the right side of the pushing device. If the speed of the conveyor belt is relatively high, when the conveyor belt stops instantly, the material will generate forward inertia, and the first positioning baffle plate can limit the forward movement of the material, so that the positioning of the material in the Y-axis direction is more accurate.

[0016] According to some embodiments of the present invention, a second cylinder connected to the first positioning baffle is provided directly above the first positioning baffle, and the first positioning baffle is moved up and down by the cylinder.

If the thrust of the pushing device is relatively large, the material will generate inertia, resulting in inaccurate positioning of the material in the X-axis direction. The second positioning baffle is provided to limit the movement of the material. The first positioning baffle, the second positioning baffle and the second pressing device work together. The first positioning baffle is first used to limit the movement of the material in the Y-axis direction, and then the pushing device is used to push the material to a predetermined position. The second positioning baffle limits the movement in the X-axis direction. Finally, the second pressing device in the vertical direction is used to press the material to achieve the purpose of limiting the movement of the material in three directions, so that accurate positioning can be achieved.

[0018] According to some embodiments of the present invention, the grinding mechanism also includes a frame, a horizontal support plate is provided under the lifting platform, the support plate is fixedly connected to the frame, a vertical third cylinder is fixed on the support plate, and a push rod of the third cylinder is connected to the lifting platform.

[0019] According to some embodiments of the present invention, a plurality of vertical guide posts are provided on the lower end surface of the lifting platform, and the guide posts penetrate the support plate and are gap-connected with the support plate. The guide posts can reduce unbalanced vibration or swing generated during the lifting process of the lifting platform, so that the lifting platform can move smoothly.

[0020] According to some embodiments of the present invention, the first platform is connected to the lifting platform via a first slide rail slider, and the second platform is connected to the first platform via a second slide rail slider, and the slide rail slider makes the movement smoother and more controllable.

[0021] According to some embodiments of the present invention, the first platform and the second platform are driven by stepper motors respectively, and the angular displacement can be controlled by controlling the number of pulses to achieve accurate positioning. The speed and acceleration of the motor rotation can be controlled by controlling the pulse frequency to achieve speed regulation, making the position adjustment of the mold more flexible and accurate.

[0032] like Figure 1-5 As shown, a battery cell electrode grinding device comprises:

[0033] The feeding mechanism 100 includes an inclined slide 160 and a first pressing device 110. A movable shifting rod 120 is provided at the end of the inclined slide 160.

The cyclic action of the cylinder can realize the continuous addition of monomer.

[0035] The conveying and clamping mechanism 200 includes a conveyor belt 250, which is located below the end of the inclined slide 160. The entire conveyor belt 250 is located on a table built with aluminum profiles. A sensor 210 and a pushing device 220 are provided on one side of the conveyor belt 250 in sequence, and a second pressing device 240 is provided on the top of the other side.

The first positioning baffle 230 is moved up and down by the cylinder connected thereto.

[0036] The monomer is transported by the conveyor belt 250. When the sensor 210 senses the monomer, a signal is fed back to the control system, the transmission belt stops, and the first positioning baffle 230 drops to limit the movement of the monomer in the Y-axis direction. At this time, the pushing device 220 extends to push the monomer along the X-axis direction to the edge of the conveyor belt 250. The second pressing device 240 drops to press the monomer to prevent it from sliding during grinding.

[0037] The grinding mechanism 300, which is adjacent to the other side of the conveyor belt 250, includes a frame 350, a lifting platform 360 and a second positioning baffle 340.

[0038] After the monomer reaches the preset location, the grinding mechanism 300 starts, rises and falls under the push of the third cylinder 370, and grinds the monomer electrode. After grinding one side of the electrode, under the control of the second stepper motor 392, the grinder 330 moves left and right to grind the other side of the electrode. At the same time, the first stepper motor 391 can be controlled by the touch screen to adjust the grinding feed amount.
