[0041] Example

[0042] Please see Figure 1 and Figure 2 , Figure 1 The diagram shown is a structural schematic of the battery film removal device 100 provided in this embodiment. Figure 2 The diagram shown is a partial structural schematic of the battery film removal device 100.

[0043] The battery film removal device 100 provided in this embodiment is used to automatically remove the insulating film from the surface of a battery. The battery film removal device 100 includes a device body 110, a carbon dioxide laser 120, and a dust removal system 130. The device body 110 has a film removal chamber 111 for accommodating the battery. The carbon dioxide laser 120 is disposed on the device body 110 and is used to irradiate the battery with carbon dioxide laser to burn the insulating film on the surface of the battery into particulate dust. The dust removal system 130 is disposed on the device body 110 and communicates with the film removal chamber 111 to remove the particulate dust from the film removal chamber 111.

[0044] In practical applications, the battery to be de-filmed is placed in the de-filming chamber 111 and irradiated with a carbon dioxide laser 120. The carbon dioxide laser 120 emits a laser wavelength of 10.6 μm, which is a long-wavelength laser. This wavelength is efficiently absorbed by the insulating film on the battery surface. The battery casing is usually made of aluminum, which has a reflectivity of over 98% for this wavelength of laser. Therefore, during laser irradiation, the insulating film rapidly heats up and undergoes a combustion reaction, transforming into particulate dust. The aluminum casing, on the other hand, does not absorb much laser energy, thus avoiding damage to the battery itself.

[0045] The dust removal system 130 is connected to the film removal chamber 111. It uses negative pressure to promptly remove particulate dust generated during laser ablation from the film removal chamber 111, preventing particulate dust from accumulating there. By combining carbon dioxide ablation with the suction from the dust removal system 130, the entire film removal process eliminates the need for manual operation, achieving a higher degree of automation and continuous operation, and improving film removal efficiency.

[0046] To dissipate heat from the carbon dioxide laser 120 and enable it to operate for extended periods, the battery film removal device 100 provided in this embodiment further includes a cooling system connected to the carbon dioxide laser 120. Preferably, the cooling system in this embodiment is a chiller, which uses a circulating pipeline to achieve water-cooled heat dissipation for the carbon dioxide laser 120.

[0047] The main body 110 of the device is provided with a safety sealing door 112 that helps to form the membrane removal chamber 111. A sealing strip is provided at the door seam of the safety sealing door 112 to prevent the leakage of particulate dust in the membrane removal chamber 111.

[0048] During the removal of the insulating film, the safety sealing door 112 remains closed to seal the film removal chamber 111, preventing particulate dust generated during the film removal process from leaking into the environment, causing pollution and endangering human health.

[0049] In order to facilitate observation of the situation inside the membrane removal chamber 111 and to protect the human eyes, in this embodiment, the safety sealing door 112 is also provided with eye-protecting glass 114, which allows the human eyes to observe the situation inside the membrane removal chamber 111.

[0050] In this embodiment, the main body 110 of the device is also provided with an automatic door assembly 115, which is used for loading and unloading batteries, thus facilitating the entry or exit of batteries into the membrane removal chamber 111. Please refer to the following reference. Figure 3 , Figure 3 The diagram shown is a structural schematic of the automatic door assembly 115.

[0051] In this embodiment, the automatic door assembly 115 includes a door body 116 that forms the membrane removal chamber 111, and a switch drive mechanism 117 for driving the door body 116 to open and close. Preferably, the drive mechanism in this embodiment is a telescopic cylinder, and the door body 116 is also provided with an eye-protecting glass 114.

[0052] In fact, the door body 116 is also equipped with a sensor for monitoring the position of a human body. When the main body 110 of the device is in operation, the switch drive mechanism 117 is used to control the main body 110 of the device to stop when the sensor detects that a human body is within a preset range of the door body 116.

[0053] In this embodiment, the sensing element is a light grating. It is understood that during the membrane removal process, the temperature inside the membrane removal chamber 111 is high and contains smoke and dust; if personnel get too close at this time, they may be injured. Therefore, by installing a sensor on the door 116, a monitoring system is established to detect the approach of a person. Once an operator is detected approaching the door 116 to a critical safe distance, all mechanisms are immediately controlled to enter a shutdown state, thereby avoiding potential personal injury risks.

[0054] Please refer to the following: Figure 4 and Figure 5 , Figure 4 The diagram shown is a schematic representation of the internal structure of the membrane removal chamber 111. Figure 5 As shown Figure 4 A magnified view of the central area.

[0055] When the carbon dioxide laser 120 ablates the insulating film on the surface of the battery, the insulating film heats up rapidly and undergoes a combustion reaction due to the highly concentrated laser energy, generating a large amount of fine dust particles and volatile gases. If only the dust removal system 130 is used for unilateral suction, it is difficult to completely capture all suspended particles, and some dust may remain in the membrane removal chamber 111.

[0056] Therefore, the battery membrane removal device 100 provided in this embodiment also includes an air knife assembly 150. The air knife assembly 150 is disposed in the membrane removal chamber 111. During the process of the carbon dioxide laser irradiating the battery, the air knife assembly 150 and the dust removal system 130 are respectively disposed on opposite sides of the battery. The air knife assembly 150 is used to blow compressed air to the battery.

[0057] The air knife assembly 150 blows high-pressure compressed air onto the battery surface to form a directional airflow field. Its direction is set opposite to the negative pressure suction path of the dust removal system 130, so that the particulate dust generated during the ablation process is quickly guided to the dust removal pipe inlet under the drive of the airflow, which improves the dust removal efficiency, reduces the degree of dispersion of particulate dust in the chamber, and obtains a better film removal effect.

[0058] In addition, the air knife assembly 150 cools the battery surface while blowing compressed air, which can suppress the formation of local high temperature zones, reduce the risk of open flame caused by overheating, and further improve the safety of the battery film removal process.

[0059] The battery membrane removal device 100 also includes a loading mechanism 160 and a transfer mechanism 170 disposed in the membrane removal chamber 111. The loading mechanism 160 is used to transport the battery fed into the membrane removal chamber 111 to a transition position, and the transfer mechanism 170 is used to transfer the battery in the transition position to the membrane removal position so that the battery is irradiated by the carbon dioxide laser 120 at the membrane removal position.

[0060] Please refer to the following: Figure 6 , Figure 6 As shown Figure 5 An enlarged schematic diagram of region A in the middle.

[0061] In this embodiment, the feeding mechanism 160 includes a feeding body 161 and a conveying component 162. The feeding body 161 has a conveying channel and a transition position at the end of the conveying channel. The conveying component 162 is disposed on the feeding body 161 and is used to carry and convey the battery to move along the conveying channel to the transition position.

[0062] In this embodiment, the conveyor 162 consists of multiple rollers arranged sequentially on the feeding body 161. When a battery is placed on the rollers, the rollers rotate, conveying the battery along the conveying channel to the transition position. In another embodiment, the conveyor 162 may also be a conveyor belt or similar structure.

[0063] The feeding body 161 includes a limiting member 1611 and a stop member 1612. The two limiting members 1611 are arranged side by side and spaced apart to form a conveying channel. The conveying member 162 is located below the conveying channel. The stop member 1612 is located at the end of the conveying channel and defines a transition position with the two limiting members 1611.

[0064] In practical applications, the battery moves between the two limiting members 1611, which can prevent the battery from tilting during transportation and allow it to reach the transition position in a stable state, thereby enabling the transfer mechanism 170 to accurately transfer the battery.

[0065] Please refer to the following: Figure 7 , Figure 7 The diagram shown is a structural schematic of the transfer mechanism 170.

[0066] The transfer mechanism 170 includes a moving module 171 and a flipping module 172. The flipping module 172 is connected to the moving module 171. The moving module 171 is used to drive the flipping module 172 to move in multiple directions. The flipping module 172 is used to clamp the battery and drive the battery to flip in the first plane to adjust the battery toward the wall of the carbon dioxide laser 120.

[0067] Specifically, the moving module 171 includes a first moving module 1711, a second moving module 1712, and a third moving module 1713. The first moving module 1711 is connected to the second moving module 1712 and is used to drive the second moving module 1712 to move vertically. The second moving module 1712 is connected to the third moving module 1713 and is used to drive the third moving module 1713 to move horizontally. The flipping module 172 is disposed on the third moving module 1713, and the third moving module 1713 is used to drive the flipping module 172 to clamp the battery and drive the battery to move horizontally.

[0068] In fact, Figure 7 The direction indicated by the X arrow is the first horizontal direction, the direction indicated by the Y arrow is the second horizontal direction, and the direction indicated by the Z arrow is the vertical direction. In this embodiment, the first plane actually refers to the vertical plane defined by the first horizontal direction and the vertical direction. In this embodiment, the first moving module 1711 is equipped with a linear motor, which can drive the second moving module 1712 to move in the vertical direction, thereby driving the third moving module 1713 and the flipping module 172 to move in the vertical direction. The second moving module 1712 is equipped with a linear motor, which can drive the third moving module 1713 to move in the first horizontal direction, thereby driving the flipping module 172 to move in the first horizontal direction.

[0069] In this embodiment, the third moving module 1713 includes two third driving members 1714 and two moving frames 1715. The two moving frames 1715 are slidably disposed on the second moving module 1712, and the two moving frames 1715 are arranged at intervals in the second horizontal direction. The two third driving members 1714 are respectively connected to the two moving frames 1715, and are used to drive the two moving frames 1715 to move in the second horizontal direction respectively.

[0070] The flipping module 172 includes two first flipping drive members 1721 and two clamping blocks 1722. The two first flipping drive members 1721 are respectively disposed on two movable frames 1715, and the two clamping blocks 1722 are respectively connected to the two first flipping drive members 1721. The two clamping blocks 1722 are used to clamp the battery as the two movable frames 1715 approach each other in the second horizontal direction. The two first flipping drive members 1721 are used to drive the two clamping blocks 1722 to rotate, thereby causing the battery to flip in the first plane. Preferably, in this embodiment, the first flipping drive member 1721 is a rotary motor.

[0071] In practical applications, when the feeding mechanism 160 transports the battery to the transition position, the first moving module 1711, the second moving module 1712, and the third moving module 1713 work together to position the two clamping blocks 1722 of the flipping module 172 on opposite sides of the battery, with the two clamping blocks 1722 slightly higher than the limiting member 1611. In this state, the two third driving members 1714 drive the two moving frames 1715 to move closer together, thereby causing the two clamping blocks 1722 to converge and clamp the battery. Afterwards, the first moving module 1711, the second moving module 1712, and the third moving module 1713 work together again to transfer the battery to the film removal position. It can be understood that the film removal position refers to the location that can be irradiated by the carbon dioxide laser 120.

[0072] After the carbon dioxide laser 120 completes the irradiation of one side of the battery, that is, after the insulating film on one side of the battery surface is removed, the two first flipping drive members 1721 are activated, causing the battery to flip in the first plane so that the other side of the battery is irradiated by the carbon dioxide laser 120. After multiple flips, the removal of the insulating film on the periphery of the battery is completed.

[0073] In this embodiment, the dust removal system 130 has an external connection 131 and a suction end 132 connected by a pipeline. The external connection 131 is used to connect an external suction device, and the suction end 132 is connected to one of two movable frames 1715 to follow the movement of the corresponding movable frame 1715. Since the suction end 132 moves synchronously with the movable frame 1715, it can always be aligned with the battery, thus obtaining a stable and reliable suction effect.

[0074] In this embodiment, at least one of the two third drive members 1714 is provided with a torque sensor. The torque sensor is used to adjust the torque of the corresponding third drive member 1714 to adapt to different types of batteries and ensure that different types of batteries can be firmly clamped by the two clamping blocks 1722.

[0075] Please refer to the following: Figure 8 , Figure 8 As shown Figure 5 A magnified view of region B in the middle.

[0076] The battery removal device 100 also includes an auxiliary flipping mechanism 180, which is disposed in an adjustment position within the removal chamber 111. The transfer mechanism 170 is also used to transfer the battery from the removal position to the adjustment position. The auxiliary flipping mechanism 180 is used to fix and drive the battery in the adjustment position to flip in a second plane to adjust the battery's orientation towards the wall of the carbon dioxide laser 120. The transfer mechanism 170 is also used to transfer the battery, after being flipped by the transfer mechanism 170, back to the removal position to be irradiated by the carbon dioxide laser 120.

[0077] Understandably, under the action of the flipping module 172, the battery can only be flipped within the first plane, and the removal of the insulating film on the multiple walls within the first plane can only be completed. The side walls held by the two clamping blocks 1722 are never exposed to light. Therefore, after the insulating film on the periphery of the battery is removed, the transfer mechanism 170 transfers the battery from the film removal position to the adjustment position. Then, the auxiliary flipping mechanism 180 fixes and drives the battery in the adjustment position to flip within the second plane.

[0078] In this embodiment, the second plane is actually a vertical plane defined by the second horizontal direction and the vertical direction. The auxiliary flipping mechanism 180 flips the battery at an angle within the second plane, so that the opposite sides of the battery with the insulating film removed correspond to the two clamping blocks 1722, exposing the two ends of the battery sequentially covered with the insulating film. Then, the transfer mechanism 170 transfers the battery, which has been flipped by the transfer mechanism 170, back to the film removal position and flips it again to remove the insulating film from both end faces under the irradiation of the carbon dioxide laser 120.

[0079] In this embodiment, the auxiliary flipping mechanism 180 includes a support frame 181, a flipping clamp 182, and a second flipping drive 183. Both the second flipping drive 183 and the flipping clamp 182 are mounted on the support frame 181. The flipping clamp 182 is used to hold the battery, and the second flipping drive 183 is connected to the flipping clamp 182, driving the flipping clamp 182 to flip the battery within a second plane. In this embodiment, the second flipping drive 183 is also a rotary motor.

[0080] In summary, the battery film removal device provided in this embodiment can automatically remove the insulating film on the surface of the battery, and has the characteristics of better effect and higher efficiency.

[0081] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
