Description

Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a standing wave suspension constraint structure and a laser die-cutting device. Background Art

[0002] The tab is an important feature of the current collector of a lithium battery and is the bridge for electric current to pass from the motor sheet to the electrode column. Due to its thin and fragile nature, it is very easy to collide with the equipment itself and produce defects. Currently, tab protection is an important issue in the laser die-cutting process, which mainly focuses on two methods: air knife tab smoothing and physical tab smoothing.

[0003] However, in related technologies, for example, a wind knife is used to blow high-speed airflow toward the side of the pole ear, and the induced effect caused by the convenient viscosity of the air fluid is used to drive the airflow above the pole ear to flow rapidly. The airflow velocity above the pole ear is relatively high and the pressure is low, resulting in a pressure difference between the airflow above and below the pole ear, and the higher-pressure airflow below the pole ear produces an upward trend, picking up the pole ear. Utility Model Content

[0004] The purpose of the embodiments of the present application is to provide a standing wave suspension constraint structure and a laser die-cutting device, which can more effectively prevent the shaking and folding of the tabs during the production process, thereby achieving a better protection effect.

[0005] An embodiment of the present application provides a standing wave suspension constraint structure, including: a baseband clock, which is used to provide a wave signal; a modulation and filtering device, which is configured to be connected to the baseband clock to modulate the wave signal; and an ultrasonic standing wave generating device, which is configured to be connected to the modulation and filtering device to interfere with the modulated wave signal and form a standing wave.

[0006] In the above implementation process, the baseband clock is connected to the modulation and filtering device, and the modulation and filtering device is connected to the ultrasonic standing wave generating device, so that when the baseband clock sends a wave signal, the modulation and filtering device executes the corresponding information, modulates the wave signal of the baseband clock, and sends the modulated waveform to the ultrasonic standing wave generating device. Then the ultrasonic standing wave generating device interferes with the waveform, which can more effectively prevent the jitter and folding of the pole ear during the production process and achieve better protection effect.

[0007] In some embodiments, the ultrasonic standing wave generating device includes a plurality of ultrasonic transducers, which are relatively distributed. By relatively distributing the plurality of ultrasonic transducers, the waveforms of different ultrasonic transducers interfere with each other, thereby interfering multiple low-pressure areas into a single low-pressure area, thereby preventing the tab from deviating.

[0008] In some embodiments, a plurality of ultrasonic transducers are distributed at intervals to form an interference space. Different ultrasonic transducers interfere with each other in the interference space, and the tabs are constrained at the nodes when they move in the interference space, thereby achieving the effect of protecting the tabs.

[0009] In some embodiments, the standing wave suspension constraint structure further comprises a driver, and the driver is configured to be connected to the ultrasonic standing wave generating device. By connecting the driver to the ultrasonic standing wave generating device, the ultrasonic standing wave generating device can convert the electrical signal strengthened by the driver into an acoustic wave signal, thereby facilitating interference.

[0010] In some embodiments, the standing wave suspension constraint structure further includes a controller, and the controller is configured to be connected to the modulation and filtering device.

[0011] In some embodiments, the standing wave suspension constraint structure further includes a power supply, and the power supply is configured to be connected to the modulation and filtering device.

[0012] In a second aspect, the present application also provides a laser die-cutting device, comprising: a pole ear; and a standing wave suspension constraint structure as described in any one of the above items, wherein the interference space of the ultrasonic standing wave generating device of the standing wave suspension constraint structure is configured to accommodate the pole ear.

[0013] In the above implementation process, the pole ear is located in the interference space, so that when the laser die-cutting device performs the laser die-cutting process, the ultrasonic standing wave generating device can interfere with the waveform, which can more effectively prevent the pole ear from shaking and folding during the production process, thereby achieving better protection effect.

[0025] Example

[0026] Tab protection is an important topic in the laser die-cutting process, and it mainly focuses on two methods: wind knife tab smoothing and physical tab smoothing. One solution is to use a wind knife to blow high-speed airflow to the side of the tab, and use the induced effect caused by the viscosity of the air fluid boundary to drive the airflow above the tab to flow rapidly. Since the airflow velocity above the tab is relatively high and the pressure is low, a pressure difference is generated between the airflow above and below the tab, and the high-pressure airflow below the tab has an upward trend, lifting the tab; another solution is to use a physical tab smoothing plate to straighten the tab, but this method will have the following problems, such as the hard material of the smoothing plate, if the tab is at the wrong angle, it will hit the smoothing plate, causing wrinkles and damage; the ability to adjust the smoothing angle is limited; repeated proofing is required, and the process is not versatile.

[0027] In view of this, if Figure 1 As shown, the present application provides a non-direct contact type pole ear constraint structure, which can more effectively prevent the shaking and folding of the pole ear during the production process; at the same time, the air fluid pressure field gradient is used to form a potential well to constrain the pole ear. Compared with the traditional solid roller or negative pressure adsorption block constraint, the force is softer, the process is more linear, and the friction risk is eliminated, thereby achieving a better protection effect.

[0028] Specifically, an embodiment of the present application provides a standing wave suspension constraint structure, including: a baseband clock 100, which is used to provide a wave signal; a modulation and filtering device 200, which is configured to be connected to the baseband clock 100 for modulating the wave signal; an ultrasonic standing wave generating device 300, which is configured to be connected to the modulation and filtering device 200 for interfering with the modulated wave signal and forming a standing wave.

[0029] In the above implementation process, the base frequency clock 100 is connected to the modulation and filtering device 200, and the modulation and filtering device 200 is connected to the ultrasonic standing wave generating device 300, so that when the base frequency clock 100 sends a wave signal, the modulation and filtering device 200 executes the corresponding information, modulates the wave signal of the base frequency clock 100, and sends the modulated waveform to the ultrasonic standing wave generating device 300, and then the ultrasonic standing wave generating device interferes with the waveform, which can more effectively prevent the jitter and folding of the tab 700 during the production process, and achieve better protection effect.

[0030] In some embodiments, the ultrasonic standing wave generating device 300 includes a plurality of ultrasonic transducers 301, and the plurality of ultrasonic transducers 301 are relatively distributed. By relatively distributing the plurality of ultrasonic transducers 301, the waveforms of different ultrasonic transducers 301 interfere with each other, thereby interfering a plurality of low pressure areas into a single low pressure area, and preventing the tab 700 from deviating.

[0031] In some embodiments, a plurality of ultrasonic transducers 301 are distributed at intervals to form an interference space. Different ultrasonic transducers 301 interfere with each other in the interference space, and the tab 700 is constrained at the node when moving in the interference space, thereby achieving the effect of protecting the tab 700.

[0032] In some embodiments, the standing wave suspension constraint structure further includes a driver 400, and the driver 400 is configured to be connected to the ultrasonic standing wave generating device 300. By connecting the driver 400 to the ultrasonic standing wave generating device 300, the ultrasonic standing wave generating device 300 can convert the electrical signal strengthened by the driver 400 into an acoustic wave signal, thereby facilitating interference.

[0033] In some embodiments, the standing wave suspension constraint structure further includes a controller 500 , and the controller 500 is configured to be connected to the modulation and filtering device 200 .

[0034] In some embodiments, the standing wave suspension constraint structure further includes a power supply 600, and the power supply 600 is configured to be connected to the modulation and filtering device 200. In other embodiments, the power supply 600 is also connected to the controller 500 and the modulation and filtering device 200 to provide power to the controller 500 and the modulation and filtering device 200, respectively.

[0035] In a second aspect, the present application further provides a laser die-cutting device, comprising: a pole ear 700; and the standing wave suspension constraint structure as described above, wherein the interference space of the ultrasonic standing wave generating device 300 of the standing wave suspension constraint structure is configured to accommodate the pole ear 700.

[0036] In the above implementation process, the tab 700 is located in the interference space, so that when the laser die-cutting device performs the laser die-cutting process, the ultrasonic standing wave generating device 300 can interfere with the waveform, which can more effectively prevent the tab 700 from shaking and folding during the production process, thereby achieving better protection effect.
