Description

Technical Field

[0002] The outer package of the existing soft-pack battery is formed by melting and heat-sealing an aluminum-plastic composite film material. Usually, during the production process, the surface of the encapsulated battery is covered with a PET film to prevent the surface of the battery core from being scratched during subsequent transportation. However, before the PET film is wrapped around the battery core, the aluminum-plastic film on the surface of the battery core has been in an exposed state. After multiple processes, more or less dust particles will be adsorbed on the surface of the aluminum-plastic film. When the battery core after the PET film is wrapped undergoes the formation and pressurization process, pit points appear in the area of the dust particles inside the PET film under the influence of pressure, posing a potential safety hazard to the battery core and not meeting the requirements of customers for the quality of the battery core product.

[0028] It is easy to understand that according to the technical solution of the present utility model, without changing the essence of the present utility model, those of ordinary skill in the art can propose various structural forms and implementation methods that can be mutually replaced. Therefore, the following detailed embodiments and the accompanying drawings are only illustrative descriptions of the technical solution of the present utility model, and should not be regarded as the whole of the present utility model or as a limitation or restriction on the technical solution of the present utility model.

[0029] Embodiment 1

[0030] Please refer to Figure 1, this embodiment introduces a dust removal tooling for the battery surface, which mainly consists of a handling mechanism 1, an ultrasonic dust removal mechanism 2, and a dust removal brush mechanism 3. The dust removal brush mechanism 3 is arranged at the feeding end of the film laminating tooling (not shown in the figure), that is, beside the guiding roller of the film laminating tooling. The ultrasonic dust removal mechanism 2 and the dust removal brush mechanism 3 are arranged linearly at the same height. The ultrasonic dust removal mechanism 2 is located in the running direction of the handling mechanism 1. The bare battery cell clamped by the handling mechanism 1 first passes through the ultrasonic dust removal mechanism 2, then through the dust removal brush mechanism 3, and finally enters the film laminating operation through the guiding roller of the film laminating tooling.

[0031] The handling mechanism 1 mainly consists of a moving part 11 and two pressing plates 12. The moving part 11 includes a screw slide table module 111, a first bracket 112, and a telescopic cylinder 113. The screw slide table module 111 is horizontally arranged, and the moving direction of the moving end of the screw slide table module 111 is on the same line as the ultrasonic dust removal mechanism 2 and the dust removal brush mechanism 3. The moving end of the screw slide table module 111 is connected to the first bracket 112. The first bracket 112 preferably has an approximately U-shaped structure. The opening direction of the first bracket 112 faces away from the moving end of the screw slide table module 111. The outer side of the first bracket 112 is connected to the moving end of the screw slide table module 111. Two telescopic cylinders 113 are longitudinally and linearly symmetrically arranged. The fixed ends of the two telescopic cylinders 113 are respectively installed at the top and bottom of the first bracket 112, and the moving ends are arranged facing each other and are respectively connected to the pressing plates 12. The detachable connection between the moving end of the telescopic cylinder 113 and the pressing plate 12 can be realized through auxiliary parts such as bolts.

[0032] It should be noted that the screw slide table module 111 can also be connected to other mechanisms such as a multi-axis manipulator to meet the movement of the overall handling mechanism 1 in other directions. Moreover, the length of the pressing plate 12 is less than the length of the bare battery cell, but the width can be greater than the width of the bare battery cell. In this way, the ends in the length direction of the bare battery cell will be outside the pressing plate 12 and can enter the guiding roller of the film laminating tooling through the ultrasonic dust removal mechanism 2 and the dust removal brush mechanism 3 without being blocked by the pressing plate 12.

[0033] Such as Figures 2 - 4As shown in the figure, the pressing plate 12 is provided with air blowing holes. The air blowing holes of the two pressing plates 12 are arranged facing each other. The air blowing holes in this embodiment include an air inlet 121, an air outlet 122, and a ventilation channel 123. On one side of the two pressing plates 12 facing each other, air outlets 122 are arranged in an array. Adjacent air outlets 122 are interconnected through the ventilation channel 123. The air inlet 121 is located on the other side of the pressing plate 12 and is communicated with one of the air outlets 122. The quick connector 13 is installed in the air inlet 121. The diameter of the air outlet 122 is preferably 1 mm. The quick connector 13 can be connected to the air blowing pipe 14. A regulating valve 15 for adjusting the gas flow rate is provided on the air blowing pipe 14. The air blowing volume is adjusted according to the dust removal effect to achieve the best dust removal effect. The end of the air blowing pipe 14 can be connected to the air outlet end of a blowing air pump (not shown in the figure). The blowing air pump serves as a power source. When the pressing plate 12 approaches the bare battery cell, air is blown onto the surface of the bare battery cell for dust removal.

[0034] As Figure 1 shown, the ultrasonic dust removal mechanism 2 mainly consists of a second bracket 21, a dust suction hood 22, and an ultrasonic dust remover 23. The second bracket 21 is in a "C" shape. The outside of the second bracket 21 can be installed with corresponding devices through other support structures or installation structures, so that the second bracket 21 can be placed in the running direction of the pressing plate 12. The number of the dust suction hoods 22 is two. There is no baffle on one side of the two dust suction hoods 22 facing each other. The ultrasonic dust remover 23 is installed inside the dust suction hood 22. The size of the ultrasonic dust remover 23 is smaller than that of the dust suction hood 22. Therefore, the ultrasonic dust remover 23 will not affect the dust suction operation at the opening of the dust suction hood 22. The ultrasonic dust remover 23 uses existing devices, including an ultrasonic transducer oscillator and an ultrasonic generator. The ultrasonic generator generates high-frequency high voltage and conducts it to the transducer through a cable connection line. The outside of the dust suction hood 22 has a connection port connected to a negative pressure device (not shown in the figure). The ultrasonic dust removal mechanism 2 uses oscillating ultrasonic waves to make the dust particles on the surface of the battery cell in a suspended state, and then uses negative pressure to suck away the dust particles to achieve the purpose of dust removal. It should be noted that the ultrasonic dust removal mechanism 2 and the bare battery cell use non-contact dust removal.

[0035] The dust removal brush mechanism 3 mainly consists of a third bracket 31 and a brush 32. The third bracket 31 is in a "C" shape. The outside of the third bracket 31 can be installed with corresponding devices through other support structures or installation structures, so that the third bracket 31 can be placed at the guiding roller of the film covering tooling. The two brushes 32 are longitudinally arranged inside the third bracket 31. The longitudinal distance between the two brushes 32 matches the thickness of the bare battery cell. Therefore, when the bare battery cell passes through the gap between the two brushes 32, the brushes 32 deeply clean the surface of the bare battery cell, and the battery cell after dust removal is immediately covered with a film. The battery surface dust removal tooling in this embodiment is applicable to soft-pack batteries of various models.

[0036] When clamping the bare battery cell, the pressing plate 12 of the present utility model blows air through the air blowing holes to the surface of the bare battery cell, and at the same time, uses the ultrasonic dust removal mechanism 2 to oscillate, so that the dust particles on the surface of the bare battery cell are in a suspended state, then uses negative pressure to suck away the dust particles, and finally uses the dust removal brush mechanism 3 to further deeply clean the surface of the bare battery cell to remove the dust particles adsorbed on the surface of the battery cell, so as to achieve the effect of removing dust particles and ensure the normal progress of the PET film coating operation.

[0037] Embodiment 2

[0038] As Figure 5 shown, this embodiment introduces a dust removal tooling for the battery surface, which has basically the same structure as the dust removal tooling for the battery surface introduced in Embodiment 1. The difference is that the air blowing holes of the pressing plate 12 in this embodiment include an air outlet cavity 124, a communication cavity 125 and an air inlet cavity 126 arranged in sequence; the air outlet cavity 124 and the air inlet cavity 126 are respectively located on two opposite sides of the pressing plate 12, the communication cavity 125 is located in the middle section inside the pressing plate 12, one end of a plurality of air outlet cavities 124 inside the pressing plate 12 is communicated with the communication cavity 125, one end of the air inlet cavity 126 inside the pressing plate 12 is communicated with the communication cavity 125, and the quick interface 13 is installed in the air inlet cavity 126. In this embodiment, all the air outlet cavities 124 are communicated with the communication cavity 125, which can realize the rapid distribution and flow of air flow.

[0039] This embodiment has the same beneficial effects as Embodiment 1.

[0040] The technical scope of the present utility model is not limited to the content described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present utility model, and these deformations and modifications should all fall within the protection scope of the present utility model.
