The air outlet 31 is conveniently set to blow deionized air to the insulating film 4 to prevent the formation of a vacuum layer and remove static electricity.

[0069] According to some embodiments of the present application, optionally, the support member 12 is provided with a accommodating cavity 121 , the ion generating device 32 is disposed in the accommodating cavity 121 , and the support member 12 is provided with an air inlet 124 , which is in communication with the accommodating cavity 121 .

[0071] According to some embodiments of the present application, optionally, an opening 122 is provided at the top of the support member 12, the opening 122 is communicated with the accommodating cavity 121, the ion generating device 32 is disposed in the accommodating cavity 121 through the opening 122, and the top of the ion generating device 32 is electrically connected to an external power supply.

[0072] like Figure 6 As shown, in some embodiments, an opening 122 is provided on the top of the support member 12, and the shape and size of the opening 122 are adapted to the shape and size of the ion generating device 32, so that the ion generating device 32 can be installed in the accommodating cavity 121. A connector 323 is provided on the top of the ion generating device 32, and the connector 323 protrudes from the top of the support member 12, so that an external power source can supply power to the ion generating device 32 through the connector 323. In this way, by setting an opening 122 on the top of the support member 12, the opening 122 is connected to the accommodating chamber 121, so that the top of the ion generating device 32 is conveniently electrically connected to an external power supply, and the external power supply supplies power to the ion generating device 32, and the connector 323 does not interfere with the air inlet 124 and the air outlet 31 of the blowing mechanism 3.

[0073] According to some embodiments of the present application, optionally, the ion generating device 32 includes an ion rod 321 and an ion needle 322 , the ion rod 321 is sleeved on the ion needle 322 , and a connector 323 electrically connected to an external power source is provided on the top of the ion rod 321 .

[0074] In other embodiments, the connector 323 may not be located at the top of the ion rod 321, as long as the external power source can supply power to the ion generating device 32, it is within the protection scope of this embodiment; In this embodiment, the external power source is alternating current, and the AC deionizing rod 321 is used to ionize the molecules in the medium such as air through a high voltage electric field to generate positive and negative ions. When the electric field strength is high enough, the electrons in the gas molecules will be excited or stripped off to form free electrons and positive ions. The ions generated by the deionizing rod 321 are blown toward the insulating film 4 to neutralize the free ions in the insulating film 4. In this embodiment, the electric field strength will change periodically with the change of the alternating current, so the electric field force on the positive and negative ions will also change periodically, causing their movement speed and direction to change continuously. Through the corona discharge, when the voltage of the alternating current is + high voltage, it will cause some ions to move in one direction, resulting in + ionization; when the voltage is - high voltage, the movement direction of the ions will be reversed, resulting in - ionization; After the original charge of the insulating film 4 is neutralized, ion accumulation caused by continuous output of ions with the same charge is prevented. By alternately outputting positive and negative ions, the amount of ions on the insulating film 4 is continuously neutralized to maintain ion balance.

[0075] In this way, the connector 323 at the top of the ion rod 321 facilitates electrical connection with an external power source, and the connector 323 at the top of the ion rod 321 can protrude from the top of the support 12 without occupying the internal space of the support 12 .

[0080] In this way, the ion generating device 32 can be conveniently fixed in the accommodating cavity 121 by means of the fasteners, thereby improving the stability of the ion generating device 32 .

[0081] According to some embodiments of the present application, optionally, the air outlet 31 extends in a vertical direction, and the air outlet 31 is a rectangular structure.

[0082] In some embodiments, the shape and extension direction of the air outlet 31 are determined by the stacking shape and stacking height of the insulating film 4. The maximum height of the air outlet 31 is adapted to the maximum height of the insulating film 4. The maximum height of the air outlet 31 is greater than the maximum height of the insulating film 4. When the uppermost insulating film 4 is taken out, the insulating film 4 can also be blown. In some embodiments, the rectangular gas outlet 31 is more convenient for gas concentration; In this way, the vertical height of the air outlet 31 is adapted to the height of the insulating film 4 stacked on the feeding mechanism 1, and the ion-containing gas blown out of the air outlet 31 is blown to the topmost insulating film 4 stacked on the feeding mechanism 1. The rectangular structure of the air outlet 31 facilitates concentrated blowing of the air outlet 31.

[0083] According to some embodiments of the present application, optionally, the blowing mechanism 3 includes more than two air outlets 31 , and the more than two air outlets 31 are arranged around the insulating film 4 on the placing mechanism 1 .

[0084] like Figure 2 and Figure 3 As shown, more than two support members 12 are provided on the bottom plate 11, and the more than two support members 12 are provided around the insulating film 4, so that more than two air outlets 31 are provided around the insulating film 4, and air can be blown around the insulating film 4 at the same time, thereby improving the blowing effect; In other embodiments, more than two support members 12 may form a wall structure, surround the insulating film 4 of the placement plate 14 in the wall, and open a plurality of air outlets 31 on the wall, which is also within the protection scope of this embodiment; In this way, more than two air outlets 31 can blow air around the insulating film 4 on the material placement mechanism 1 at the same time, thereby improving the effect of deionizing air blowing.

[0085] According to some embodiments of the present application, optionally, a scraping module 13 is provided on the material placement mechanism 1 , and the scraping module 13 is located on the side of the insulating film 4 .

Each support member 12 is provided with a brush, so that multiple brushes are also arranged around the insulating film 4. Through the multiple brushes, the insulating film 4 can be contacted around during the mold removal process of the insulating film 4, so that two or more insulating films 4 can be separated and divided; In this way, the scraping module 13 can be used to scrape the insulating film 4 when the film taking mechanism 2 takes the film, thereby reducing the possibility of the film taking mechanism 2 taking double or multiple films, further reducing the failure rate of the film packaging, avoiding failure of the blowing mechanism 3, and preventing errors and fools.

[0087] According to some embodiments of the present application, optionally, the ion generating device 32 is connected to the air path 33 of the blowing mechanism 3 , and the blowing direction of the air outlet 31 of the blowing mechanism 3 is at least partially the same as the plane direction of the insulating film 4 .

[0088] like Figure 8 and Fig. 9 As shown, in some embodiments, the ion generating device 32 is located in the gas path 33 of the blowing mechanism 3, that is, the ion-containing gas generated by the ion generating device 32 is in the middle of the gas path 33 of the blowing mechanism 3 and will not be lost; The air outlet 31 of the air blowing mechanism 3 can blow toward the insulating film 4 from a horizontal plane, or blow obliquely downward toward the insulating film 4, or blow obliquely upward toward the insulating film 4, all within the protection scope of this embodiment; The gas outlet 31 of the blowing mechanism 3 cannot blow upward toward the bottom of the insulating film 4 in the vertical direction, so that the uppermost insulating film 4 cannot be blown to the ion-containing gas, making the effect of the blowing mechanism 3 ineffective; In this way, the ion generating device 32 is connected to the air path 33 of the blowing mechanism 3, the ion generating device 32 generates ion-containing gas, which is then blown out from the air outlet 31 of the blowing mechanism 3, and the blowing direction of the air outlet 31 of the blowing mechanism 3 is at least partially the same as the plane direction of the insulating film 4, so that the blowing mechanism 3 blows toward the insulating film 4 from the side of the insulating film 4, avoiding the blowing mechanism 3 blowing toward the insulating film 4 from the bottom of the insulating film 4.

[0089] According to some embodiments of the present application, optionally, the blowing direction of the air outlet 31 of the blowing mechanism 3 is the plane direction where the insulating film 4 is located, or is obliquely downward.

[0090] In this way, the blowing direction of the air outlet 31 of the blowing mechanism 3 is in the plane direction of the insulating film 4, or in an oblique downward direction, so as to avoid the formation of a vacuum layer between two or more insulating films 4 and reduce the possibility of electrostatic adsorption.

[0091] According to some embodiments of the present application, optionally, the device further includes: A controller 5, the controller 5 includes a processor, and the processor is used to execute a computer program; An image sensor 6, which is connected to the controller 5 and is used to obtain image information of the placed insulating film 4 and send the image information to the controller 5; The air flow valve 7 is arranged in the air path 33 of the blowing mechanism 3, and is used to control the switch of the air path 33 and the air flow rate; The valve controller 8 is connected to the airflow valve 7 and is in communication with the controller 5, and is used to receive the valve control signal from the controller 5, and control the switch and opening of the airflow valve 7 according to the valve control signal; A computer program which, when executed by a processor, performs the following steps: Acquire image information sent by the image sensor 6, the image information including image information of the placed insulating film 4; According to the image information and the preset blowing algorithm, the blowing related parameters are obtained, and the blowing related parameters include blowing airflow related parameters; According to the blowing related parameters, the valve control information is sent to the valve controller 8.

[0092] The principle that the controller 5 controls the valve controller 8 and the air flow valve 7 according to the image sensor 6 is the existing control logic, and the specific structure will not be described again here.

[0093] In some embodiments, it is possible to select whether to start air blowing or deionized air blowing according to the area size and thickness of the insulating film 4 . The area size and thickness of the insulating film 4 determine the weight of the insulating film 4 . Conventional insulating film 4, such as insulating film 4 with a size of 200mm*200mm, can only open the blowing, and insulating film 4 with a size exceeding 250mm*250mm can open the deionized blowing; The principle by which the image sensor 6 obtains the area size of the insulating film 4 is a conventional technical means and will not be described again here.

[0094] In this way, the image information of the placed insulating film 4 can be obtained through the image sensor 6, and the switch and opening of the airflow valve 7 can be controlled according to the valve control signal. The switch and opening size of the blowing can be adjusted according to the area size of the insulating film 4 to avoid excessive airflow blowing away the insulating film 4 and too small airflow resulting in poor blowing effect.

[0096] The controller 5 is controlled according to the principle of the image sensor 6 according to the existing control logic, which will not be described in detail here.

[0097] like Fig.10 As shown, the image sensor 6 is electrically connected to the controller 5 , the controller 5 is connected to and controls the deionization generating device 32 , the valve controller 8 and the film taking mechanism 2 , and the valve controller 8 is connected to and controls the airflow valve 7 .

[0098] In other embodiments, when the insulating film 4 is small in area, made of good material, not prone to static electricity and not prone to adhesion, the brush can be used to separate the sheets. For the insulating film 4 whose size exceeds the first preset value, only air can be blown; For the insulating film 4 whose size exceeds the second preset value, the ion generating device 32 may be turned on to blow away the ion gas; It can increase the compatibility of equipment and reduce equipment energy consumption.

[0099] In some embodiments, the air flow valve 7 needs to be opened only during or before film removal, that is, the blowing mechanism 3, the deionizing generator 32 and the film removal mechanism 2 are controlled in linkage. In other embodiments, the blowing mechanism 3 and the deionizing generator 32 can be opened or closed by a manual button, which is within the protection scope of this embodiment.

[0100] In this way, the switch and electric field strength of the ion generating device 32 can be controlled by the controller 5 to avoid safety hazards and avoid unnecessary consumption caused by long-term idling of the ion generating device 32. When the area of ​​the insulating film 4 is small, the electrostatic adsorption force generated by the insulating film 4 also decreases synchronously. There is no need to turn on the ion generating device 32. It is only necessary to use the air flow valve 7 to increase the air flow to avoid the formation of a vacuum layer between the insulating film 4, thereby achieving the effect of preventing the insulating film 4 from sticking, thereby increasing the equipment life and reducing resource consumption.

[0101] In a second aspect, the present embodiment also relates to a battery production line, comprising a device for loading insulating films as described above.

[0102] In some embodiments, deionized air is blown on the insulating film 4 to prevent the formation of a vacuum layer between the insulating films 4, remove static electricity, and avoid double or multiple films being taken during the molding process, thereby reducing the failure rate of the packaging.

[0103] In a third aspect, this embodiment also relates to a method for loading a battery insulating film, comprising the following steps: Placing the insulating film 4 on the material placement mechanism 1; Acquire the area and thickness information of the insulating film 4, select whether to start the blowing mechanism 3 and whether to start the ion generating device 32, and blow air or deionize the insulating film 4; The film taking mechanism 2 takes the insulating film 4 .

[0104] like Fig.11 As shown, this embodiment uses the area and thickness information of the insulating film 4 to select whether to turn on the blowing mechanism 3 and whether to turn on the ion generating device 32 to blow air or blow away ion gas on the insulating film 4, thereby avoiding the formation of a vacuum layer between the insulating films 4 to prevent the insulating films 4 from sticking, thereby reducing the failure rate of the envelope, increasing the equipment life and reducing resource consumption.

[0106] In this way, whether the blowing airflow is turned on and the size of the blowing airflow are controlled according to the image information of the placed insulating film 4 and the preset blowing algorithm, thereby increasing the life of the equipment and reducing resource consumption.

[0107] According to some embodiments of the present application, optionally, the following steps are further included: According to the image information and the preset blowing algorithm, deionization generation parameters are obtained, and the deionization generation parameters include parameters related to the electric field strength of the ion generating device 32; According to the deionization generation parameters, a deionization generation signal is sent to the ion generation device 32.

[0108] In some embodiments, only air may be blown for the insulating film 4 whose size exceeds the first preset value; For the insulating film 4 whose size exceeds the second preset value, the ion generating device 32 may be turned on to blow away the ion gas; The size of the blowing airflow can be adjusted according to the size of the insulating film 4, which can increase the compatibility of the equipment and reduce the energy consumption of the equipment.

[0109] In this way, deionization generation parameters are obtained according to the image information and the preset blowing algorithm to control whether the ion generating device 32 is turned on and the electric field strength of the ion generating device 32, thereby further improving the equipment life and reducing resource consumption.

[0110] In some embodiments, a device for loading insulating film includes a loading mechanism 1, a film taking mechanism 2 and a blowing mechanism 3, the loading mechanism 1 includes a base plate 11, two or more support members 12 and a placement plate 14, the placement plate 14 is arranged on the base plate 11, the shape of the placement plate 14 is adapted to the shape of the insulating film 4, the two or more support members 12 are arranged on the base plate 11, and the two or more support members 12 are arranged around the placement plate 14; the blowing mechanism 3 includes an air outlet 31, an ion generator 32 and an air path 33, each support member 12 is provided with an air outlet 31, the air outlet 31 is arranged toward the insulating film 4 on the loading mechanism 1, the ion generator 32 is connected to the air outlet 31, the ion generator 32 is used to generate ion-containing gas, and the air outlet 31 blows the ion-containing gas toward the insulating film 4; thereby, the insulating film 4 is destaticized, a vacuum layer is prevented from being formed between the insulating film 4, and double or multiple sheets of the insulating film 4 are avoided during the mold taking process, thereby reducing the failure rate of the film.
