Description

Technical Field

[0001] The utility model belongs to the technical field of dust removal equipment, and particularly relates to a metal dust removal system. Background Art

[0002] Currently, the connection between the external tabs and the electrode current collectors of soft-pack batteries is primarily achieved through ultrasonic welding. This welding principle operates on metal-on-metal friction, and the friction process inevitably generates some metal dust. This metal dust can splash onto the insulating adhesive where the tabs are not connected, causing the adhesive to lose its insulating properties. This can lead to corrosion of the aluminum-plastic film during battery use, potentially leading to battery failure. This friction process generates a certain amount of metal dust, and while existing structures can remove most of this metal dust through negative pressure dust removal, a small amount can still adhere to the insulating adhesive on the external tabs. The metal dust generated by welding is hot and can melt onto the insulating adhesive, damaging its insulating properties.

[0003] Therefore, it is urgent to propose a new technical solution to solve the above problems. Utility Model Content

[0026] The following is combined with Figures 1 to 3 The present invention is further described in detail with reference to the following specific embodiments, but is not intended to limit the present invention.

[0027] Example 1

[0028] A metal dust removal system includes a protective film 1, a drive assembly 2, a cleaning assembly 3, and a dust collection assembly 4. The protective film 1 is used to protect the insulating adhesive. The protective film 1 is a high-temperature resistant protective film that can be selected as needed and is not specifically limited here. The drive assembly 2 is used to drive the protective film 1 to move. The cleaning assembly 3 and the protective film 1 are arranged adjacent to each other. The cleaning assembly 3 is used to clean the dust on the protective film 1. The dust collection assembly 4 is arranged on the outside of the cleaning assembly 3. The drive assembly 2 is arranged along the running direction of the protective film 1. The cleaning assembly 3 and the dust collection assembly 4 are both arranged perpendicular to the running direction of the protective film 1. The dust collection port of the dust collection assembly 4 faces the cleaning assembly 3. The dust collection assembly 4 is used to clean the cleaning assembly 3, so that the dust removed from the protective film 1 by the cleaning assembly 3 can be quickly transferred away, and the cleanliness of the cleaning assembly 3 is also ensured, thereby improving the cleaning effect of the cleaning assembly 3. By providing the protective film 1, the insulating adhesive can be prevented from being contaminated by dust. The protective film 1 can then be cleaned by the cleaning assembly 3, so that the protective film 1 covering the surface of the insulating adhesive is always neat, thereby improving the protective effect. During welding, a layer of high-temperature resistant protective film 1 is added to the insulating glue position, which covers the surface of the insulating glue during welding to prevent the high-temperature metal dust generated by welding from adhering to the insulating glue. After welding, before the next tab welding, the protective film 1 needs to be cleaned by the cleaning component 3. The cleaning component 3 can be a negative pressure dust removal device to ensure that it is neat every time it is covered on the surface of the insulating film. By setting the protective film 1, the problem of the insulating glue of the external tab being melted by the welding metal dust, resulting in the failure of the insulation performance, is solved. The protective film 1 that has been protected by welding is driven by the driving component 2 to move to the cleaning component 3 for cleaning, so that the protective film 1 can be cleaned as the equipment moves, can be reused, and reduces the cost of use.

[0029] In this embodiment, the cleaning assembly 3 includes a first cleaning wheel 31 and a second cleaning wheel 32, which are arranged on opposite sides of the protective film 1. The first cleaning wheel 31 and the second cleaning wheel 32 are respectively arranged on the two surfaces of the protective film 1, so that both surfaces of the protective film 1 can be cleaned simultaneously, thereby improving the cleaning effect.

[0030] In this embodiment, the outer side of the first cleaning wheel 31 is provided with first bristles 311, which are animal hair or PA nylon bristles. By providing the first bristles 311, the metal powder is more easily removed from the protective film 1, thereby enhancing the cleaning effect.

[0031] In this embodiment, the outer side of the second cleaning wheel 32 is provided with second bristles 321, which are animal hair or PA nylon bristles. By providing the second bristles 321, the metal powder is more easily removed from the protective film 1, thereby enhancing the cleaning effect.

[0032] In this embodiment, the dust collection assembly 4 includes a first dust collector 42 and a second dust collector 43. The first dust collector 42 is arranged outside the first cleaning wheel 31, and the dust collection port of the first dust collector 42 faces the first cleaning wheel 31. The second dust collector 43 is arranged outside the second cleaning wheel 32, and the dust collection port of the second dust collector 43 faces the second cleaning wheel 32. This arrangement allows the metal dust cleaned by the first cleaning wheel 31 or the second cleaning wheel 32 to be quickly sucked away by the first dust collector 42 or the second dust collector 43, thereby avoiding secondary contamination of the protective film 1 and improving the cleaning effect.

[0033] In this embodiment, the drive assembly 2 includes at least four drive bearings 21, which are spaced apart and arranged along the running direction of the protective film 1. The outer sides of the drive bearings 21 abut against the surface of the protective film 1. The drive bearings 21 can drive the protective film 1 to rotate, thereby achieving cleaning of different positions of the protective film 1.

[0034] In this embodiment, a cover 41 is provided at the opening of the dust collection component 4. The cover 41 can improve the dust collection effect of the dust collection component 4 and prevent metal dust from scattering and contaminating the protective film 1 at other positions.

[0035] Example 2

[0036] This embodiment differs from embodiment 1 in that it further includes a controller 5, and the driving component 2, the cleaning component 3, and the dust collection component 4 are all electrically connected to the controller 5. By setting the controller 5, the rotation speed of the driving component 2 can be controlled, thereby controlling the moving speed of the protective film 1, and the cleaning intensity of the cleaning component 3 and the dust collection strength of the dust collection component 4 can also be controlled. The driving component 2 is a device that cooperates with a conventional transmission wheel and a motor. The protective film 1 can be placed on the transmission wheel. When the transmission wheel rotates, the protective film 1 will also rotate together. The driving component 2 can also be a combination of multiple independently rotating electric wheels.

[0037] In this embodiment, a detector 6 is provided on the outside of the protective film 1 to detect the cleanliness of the protective film 1. The detector 6 is electrically connected to the controller 5. By providing the detector 6, the cleanliness of the protective film 1 can be monitored and the data can be sent to the controller 5. The controller 5 can control the speed of the driving component 2, the cleaning force of the cleaning component 3, and the suction force of the dust collection component 4 based on the feedback data, thereby achieving precise cleaning of the protective film 1.

[0038] In this embodiment, the controller 5 is provided with a trigger signal unit 51, and the detector 6, the cleaning assembly 3, and the dust collection assembly 4 are all electrically connected to the trigger signal unit 51. After the detector 6 detects the protective film 1 with metal dust, it sends a signal to the trigger signal unit 51. The trigger signal unit 51 processes the signal and sends instructions to the cleaning assembly 3 and the dust collection assembly 4. Then, the cleaning assembly 3 and the dust collection assembly 4 are started and are ready to clean the metal dust area.

[0039] In this embodiment, the detector 6 is provided with an image acquisition unit 61 and an appearance detection unit 62. The image acquisition unit 61 is used to acquire an image of the appearance of the protective film 1, and the appearance detection unit 62 is used to detect areas of the protective film 1 containing dust. The image acquisition unit 61 and the trigger signal unit 51 are both electrically connected to the appearance detection unit 62. The image acquisition unit 61 can be a CCD camera, and the appearance detection unit 62 is provided with an image comparison circuit. The appearance detection unit 62 is disposed within the detector 6. After the CCD camera acquires an image of the protective film 1, the CCD camera transmits the image signal to the image comparison circuit. The image comparison circuit recognizes the image of the protective film 1, thereby converting the metal dust signal into a corresponding electrical signal, which is then transmitted to the trigger signal unit 51 of the controller 5.

[0040] In this embodiment, the controller 5 is further provided with a main control unit 52, which is electrically connected to the trigger signal unit 51. The trigger signal unit 51 performs initial processing on the received data and then sends it to the main control unit 52. The main control unit 52 processes the data uniformly and then sends instructions back to the trigger signal unit 51. The trigger signal unit 51 then sends signals to drive other devices to operate. The main control unit 52 can be a single-chip microcomputer chip, an STM32 chip, or an ARM chip.

[0041] In this embodiment, a rangefinder or length meter is provided between the detector 6 and the cleaning assembly 3. The rangefinder or length meter is used to detect the length of the protective film 1 between the controller 5 and the cleaning assembly 3. The rangefinder or length meter is electrically connected to the main control unit 52. The rangefinder may be a laser radar rangefinder, and the length meter may be a length-measuring encoding roller. By measuring the distance or length, the area of ​​the protective film 1 containing metal dust can be accurately marked to avoid misalignment of the mark and improve the accuracy of the mark.

[0042] In this embodiment, the trigger signal unit 51 is electrically connected to the display 7. By providing the display 7, the user can objectively see the status information of the device, such as the rotation speed of the driving component 2, the rotation speed of the cleaning component 3 and the suction force of the dust collection component 4, thereby optimizing the user experience.

[0043] In this embodiment, the controller 5 may be a PLC controller or an MCU controller.

[0044] The other structures of this embodiment are the same as those of embodiment 1 and will not be described again here.

[0045] Obviously, the utility model includes a protective film, a driving component, a cleaning component and a dust collection component. The protective film is used to protect the insulating glue. The protective film is a high-temperature resistant protective film, which can be selected according to needs and is not specifically limited here. The driving component is used to drive the protective film to move. The cleaning component and the protective film are arranged adjacent to each other. The cleaning component is used to clean the dust on the protective film. The dust collection component is arranged on the outside of the cleaning component. The dust collection port of the dust collection component faces the cleaning component. The dust collection component is used to clean the cleaning component so that the dust cleaned from the protective film by the cleaning component can be quickly transferred out, which also ensures the cleanliness of the cleaning component and improves the cleaning effect of the cleaning component. By setting the protective film, the insulating glue can be prevented from being contaminated by dust. The protective film can be cleaned by the cleaning component so that the protective film covering the surface of the insulating glue is neat every time, thereby improving the protection effect. During welding, a layer of high-temperature resistant protective film is added to the insulating glue position. During welding, it covers the surface of the insulating glue to prevent the high-temperature metal dust generated by welding from adhering to the insulating glue. After welding, before the next tab welding, the protective film needs to be cleaned by a cleaning component. The cleaning component can be a negative pressure dust removal device to ensure that the surface of the insulating film is clean every time it is covered. By providing a protective film, the problem of insulation failure caused by the melting of welding metal dust on the insulating glue of the external tab is solved. In addition, the protective film that has been protected by welding is moved to the cleaning component for cleaning by the driving component, so that the protective film can be cleaned as the equipment moves, can be reused, and reduces the cost of use.
