Description

Technical Field

[0001] The present invention belongs to the field of battery slitting, and particularly relates to a blade adjusting mechanism, a battery slitting device, and a tool setting method. Background Art

[0002] The battery pole piece slitting process plays a crucial role in the new energy industry. Currently, the main factor restricting the battery pole piece slitting process is that the efficiency is still very low when replacing and debugging the slitting blades. The main reason for the above problem is that in the existing device, since the upper and lower tool shafts are respectively driven by synchronous motors to rotate, the upper tool carrier parts all adopt the same structure as the Figure 1 middle and lower tool carriers. This tool carrier structure is complex, and the blades on the tool carrier cannot be taken out and replaced individually. When replacing the blades, the entire upper tool carrier needs to be disassembled. The upper tool disc adopts a structure of a spring tightly attached inside a sleeve, which is prone to cause cumulative errors of excessive end face runout and radial runout of the upper tool, seriously affecting the slitting quality. Further, since the upper and lower tool shafts are respectively driven by synchronous motors to rotate, due to technical constraints, there will always be sliding friction between the upper and lower blades, wearing the blades, reducing the service life, and affecting the slitting quality.

[0003] At the same time, the upper tool uses external exposed threads to adjust the tool setting. Thread damage, poor maintenance, and inflexible rotation make it difficult to ensure a proper bonding force; if the bonding force is too small, collapse and edge loss will occur, and if it is too large, the blade itself will wear more severely, affecting the service life. If excessive force is applied, the tool tip will be chipped, and it is not easy to detect.

[0004] Furthermore, the existing device has a strong dependence on the experience of operators. The tool setting process depends entirely on visual observation, and it is impossible to analyze the relationship and influence between the slitting quality and the accuracy of the equipment itself, the quality of the blades themselves, and the correct debugging of the tools through effective data. Summary of the Invention

[0065] Embodiment Three

[0066] The usage method of the battery cutting device in the embodiment of the present invention includes

[0067] S1. Installation: Use a precision guide rail to hang the upper tool rest as the cross beam, and there is no need to install the original upper tool shaft. The upper tool performs power-free cutting, and the lower tool shaft spacer is increased with avoidance grooves for two-sided use, saving the time for disassembling and adjusting the lower tool shaft once.

[0068] S2. Detection: Detect the blade reference parts of the upper and lower tool shafts, and the results need to meet the requirements (it is not necessary to detect each time according to the usage status, and it is recommended to conduct spot checks regularly).

[0069] S3. Tool setting: It is recommended to use kanban management for data collection, record the zero value, debugging value, the material to be cut, the usage time, shift, etc. for the tool rest assembly and the upper tool rest.

[0070] Use a piece of waste upper blade and a multimeter. First, gently adjust the upper and lower micrometer knobs so that the upper blade lightly touches the middle of the lower blade. When the multimeter shows connection, it is the zero position value. Gently adjust the left and right micrometer knobs so that the tip of the upper blade lightly touches the end face of the lower blade. When the multimeter shows connection, it is the zero position value. As long as the tool shaft and guide rail are disassembled, the tool setting matters must be carried out to update the zero position value. When replacing the blade without disassembling the tool shaft and guide rail, there is no need to carry out the tool setting matters, and just follow the previous data for the bite amount and the adhesion force.

[0071] S4. Tool setting: Replace with a new blade, calculate and adjust the bite amount according to the thickness and strength of the slit material and lock it. Then adjust the adhesion force (the linear relationship of the adhesion force size can be provided on the certificate after the adhesion force experiment is done by our company's laboratory) and lock it.

[0072] S5. Trial cutting: Take a small amount of slit material, gently push it into the bite point, and then rotate the lower tool shaft evenly by hand for trial slitting. Magnify and judge the fracture quality and effect under the microscope, and use this as the basis for fine-tuning and correcting the bite amount and the adhesion force. The lower tool shaft 5 is connected to the motor through the transmission coupling 2 and rotates. The lower tool shaft 5 drives the lower blade 8 to rotate. Through the static friction force generated by the contact between the upper blade 7 and the lower blade 8, the lower blade 8 drives the upper blade 7 to rotate simultaneously.
