Description

Technical Field

[0001] This application relates to the field of power battery production technology, and in particular to a light-transmitting conveying device, conveying system and stacking machine. Background Technology

[0002] Electrodes are the carriers for storing and releasing electrical energy in power batteries. They are formed by coating active materials onto a metal substrate to form thin sheets. Through the cooperation of positive and negative electrodes, separators, and electrolytes, electrochemical reactions can be completed during the charging and discharging process of the battery.

[0003] After electrode production, a core-bonding process is required. This process involves combining the electrode and separator through lamination and hot pressing to form a core. During core-bonding, it is crucial to ensure the electrode dimensions are consistent. Therefore, visual inspection components are used to check the electrode dimensions to ensure the edge neatness of the bonded core, thereby guaranteeing its safe use in subsequent applications.

[0004] In practical applications, the objects inspected by the vision inspection component are electrodes on a conveyor belt. To ensure that the light used for inspection covers the corners of the electrodes during the inspection process, the width of the conveyor belt needs to be configured to be less than the length of the electrodes, so that both ends of the electrodes can extend beyond the conveyor belt along their length and be illuminated by the light. Therefore, the conveyor belt has low applicability to electrode sizes, and the electrodes extending beyond the conveyor belt will contact the conveyor belt's support components, increasing the risk of damage to the electrodes due to friction.

[0064] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments in this application specification, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection claimed in this application.

[0065] In the description of the embodiments of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0066] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a replaceable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0067] Please see Figure 1 and Figure 2 The first aspect of this application provides a light-transmitting conveying device, including a conveyor belt 100 and a support assembly 200. The support assembly 200 serves as a support structure for the conveyor belt 100, enabling the conveyor belt 100 to convey materials on the support assembly 200. The material may be, for example, an electrode sheet. The conveying direction of the conveyor belt 100 is as follows: Figure 1 The x-axis direction in the diagram.

[0068] In this embodiment, the support assembly 200 is provided with a vacuum chamber 210 opening towards the conveyor belt 100; the vacuum chamber 210 is connected to a vacuum generator, enabling it to generate a vacuum adsorption force. The conveyor belt 100 is perforated with a plurality of adsorption holes 110; when the adsorption holes 110 connect to the vacuum chamber 210, they generate an adsorption force. Specifically, as the conveyor belt 100 moves, the adsorption holes 110 circulate around the support assembly 200. When the adsorption holes 110 move to the top surface of the support assembly 200 and connect with the vacuum chamber 210, they generate a vacuum adsorption force to adsorb the electrode sheet, improving the fixation effect of the electrode sheet during transport and preventing localized lifting of the electrode sheet, which would affect the accuracy of the detection.

[0069] In practical applications, the adsorption holes 110 can be configured so that all the electrodes on the conveyor belt 100 can be adsorbed by the adsorption holes 110.

[0070] In this embodiment, the conveyor belt 100 is light-transmitting. As one implementation, the conveyor belt 100 is made of a light-transmitting material, such as PU material, which has good flexibility and tear resistance, and has a light transmittance of more than 80%, allowing light to pass through.

[0071] During the inspection of materials on the conveyor belt 100, the vision inspection component can directly perform optical dimension inspection on the electrodes on the conveyor belt 100. Specifically, the vision inspection component has a light-emitting element 510 capable of emitting light; the light-emitting element 510 can provide light for electrode dimension inspection and positioning. In this embodiment, the light emitted by the light-emitting element 510 disposed within the conveyor belt 100 can penetrate the conveyor belt 100 and directly illuminate the electrodes, thereby providing direct light to the electrodes and the inspection lens. Therefore, the electrodes conveyed by the conveyor belt 100 can be completely placed within the conveyor belt 100 without extending beyond the conveyor belt 100.

[0072] In practical applications, the width of the conveyor belt 100 can be configured to be greater than the maximum length of the electrode sheets currently produced, enabling the conveyor belt 100 to transport various electrode sheets. During transport, the electrode sheets do not need to extend beyond the conveyor belt 100 to be illuminated by light, thus avoiding the risk of friction between the electrode sheets and areas outside the conveyor belt 100. It should be noted that when the width of the conveyor belt 100 is the same as that of existing conveyor belts, the conveyor belt 100 provided in this embodiment can be compatible with conveying electrode sheets whose length is shorter than its width, thus also improving the applicability to electrode sheet transport sizes.

[0073] In a further improved embodiment, the support assembly 200 includes a support plate 220; the support plate 220 covers the vacuum chamber 210; the support plate 220 is provided with a plurality of strip holes 221; the length direction of the strip holes 221 is parallel to the conveying direction of the conveyor belt 100; the strip holes 221 communicate with the vacuum chamber 210.

[0074] Please see Figures 1 to 4 In this embodiment, the support plate 220 serves as one of the support structures for the conveyor belt 100, and its bottom can be connected to the vacuum inlet pipe 222 of the vacuum generator. After the vacuum generator, the vacuum chamber 210 generates a vacuum suction force through the vacuum inlet pipe 222.

[0075] In a more specific embodiment, the light-transmitting conveying device further includes a drive assembly 300; the drive assembly 300 is disposed on the support assembly 200, and the output end of the drive assembly 300 is connected to the conveyor belt 100; the support assembly 200 includes a support body 230 and two driven rollers 240; the two driven rollers 240 are disposed on both sides of the support body 230 along the conveying direction; the conveyor belt 100 can be driven by the drive assembly 300 to convey around the support body 230 and the two driven rollers 240.

[0076] In application, the drive assembly 300 can be located in the middle below the support plate 220; the drive assembly 300 can use the existing conveyor belt drive structure, which will not be described in detail in this embodiment. The driven roller 240 can play a steering and supporting role, so that the support plate 220, the drive assembly 300 and the driven roller 240 form a modular whole device, which facilitates the disassembly, assembly and maintenance of the light-transmitting conveyor device.

[0077] In one embodiment, see Figures 1 to 5 The light-transmitting conveying device also includes a dust removal component 400; the dust removal component 400 includes a brush roller 410 and a brush roller drive 440; the brush roller 410 abuts against the conveying surface of the conveyor belt 100; the brush roller drive 440 is connected to the brush roller 410 and is used to drive the brush roller 410 to rotate.

[0078] The brush roller drive 440 can be a rotary motor. After the brush roller drive 440 is started, it can drive the brush roller 410 to rotate, so that the soft bristles on the brush roller 410 clean the conveyor surface of the conveyor belt 100, preventing dust on the conveyor surface from affecting the conveyed electrode. Here, the conveyor surface of the conveyor belt 100 refers to the side that contacts the electrode.

[0079] Optionally, please refer to Figures 1 to 7The dust removal assembly 400 also includes a dust collection box 420 and a dust removal pipe 430; a brush roller 410 is rotatably disposed within the dust collection chamber of the dust collection box 420; the dust removal pipe 430 is disposed inside the conveyor belt 100, and the length direction of the dust removal pipe 430 is the width direction of the conveyor belt 100; the dust removal pipe 430 is provided with a plurality of air blowing holes 431; the air blowing holes 431 face the inner surface of the conveyor belt 100 and the dust collection box 420. The length direction of the dust removal pipe 430 is as follows: Figure 6 As shown in the Y-axis direction, it is perpendicular to the conveying direction of the conveyor belt 100.

[0080] In this embodiment, the inner surface of the conveyor belt 100 is the inner end face that does not contact the electrode. The conveyor belt 100 passes between the brush roller 410 and the dust removal pipe 430, and both the conveying surface and the inner surface of the conveyor belt 100 can be cleaned simultaneously through the brush roller 410 and the dust removal pipe 430, improving the conveying effect of the conveyor belt 100. Specifically, during the cleaning process, the brush roller 410 performs contact cleaning, while the dust removal pipe 430 performs blowing cleaning of the conveyor belt 100 through the air blowing hole 431, preventing residual dust on the inner surface from falling off due to vibration or other reasons during conveyor belt operation and contaminating the electrode.

[0081] In one embodiment, the dust removal assembly 400 further includes a dust removal frame 460; the dust collection box 420 and the dust removal pipe 430 are both vertically and vertically mounted on the dust removal frame 460.

[0082] Correspondingly, the dust removal assembly 400 may include a lifting drive device for controlling the lifting and lowering of the dust removal frame 460; the dust removal pipe 430 is disposed on the dust removal box 420 to achieve synchronous lifting and lowering with the dust removal box 420. By controlling the lifting and lowering of the dust removal box 420 and the dust removal pipe 430, the cleaning position can be flexibly adjusted to ensure that the brush roller 410 can effectively abut against the conveyor belt 100.

[0083] In a more specific embodiment, the air blowing hole 431 includes an interconnected hole-shaped portion 432 and a linear portion 433; the length direction of the linear portion 433 is the length direction of the dust removal pipe 430, that is... Figure 6 The Y-axis direction in the diagram.

[0084] In this embodiment, the perforated portion 432 can be circular or square, with an inner diameter larger than the width of the linear portion 433. The perforated portion 432 can provide a higher-velocity airflow to directly impact the inner surface of the conveyor belt 100, thereby blowing off dust. The linear portion 433 can diffuse the airflow and form a guiding barrier to direct the dust blown off by the perforated portion 432 to the dust collection box 420, avoiding situations where only the perforated portion 432 is provided, resulting in dust being stirred up, or where only the linear portion 433 is provided, resulting in poor sweeping effect.

[0085] In one embodiment, the dust removal assembly 400 further includes a vacuum dust removal pipe 450 connected to the dust removal system; the vacuum dust removal pipe 450 is connected to one side of the dust collection box 420; a strip-shaped slot 421 is provided on one side of the dust collection box 420; the strip-shaped slot 421 connects the dust collection chamber and the vacuum dust removal pipe 450.

[0086] In application, the vacuum dust removal pipe 450 can be disposed at the bottom of the dust collection box 420; correspondingly, the strip-shaped slot 421 is disposed at the bottom of the dust collection box 420. In this embodiment, the length direction of the strip-shaped slot 421 can be the Y-axis direction mentioned above. During the dust removal process, the dust removal system uses the vacuum dust removal pipe 450 to generate an adsorption force in the dust collection box 420, so as to guide the dust brushed off by the brush roller 410 to the dust removal system. By providing the strip-shaped slot 421, secondary pollution to the conveyor belt 100 can be reduced when backflow occurs due to large airflow.

[0087] In one embodiment, the dust collection box 420 includes a first housing 423 and a second housing 422; the second housing 422 is sleeved inside the first housing 423, and a gap 424 is formed between the first housing 423 and the second housing 422; the strip-shaped slot 421 penetrates the first housing 423 and the second housing 422, and communicates with the gap 424.

[0088] When backflow occurs due to factors such as high airflow, the backflowing gas will first enter the gap 424, which can further reduce the impact of backflow on the conveyor belt 100.

[0089] A second aspect of this application provides a conveying system, including a vision inspection component and a light-transmitting conveying device as described above; the vision inspection component includes a light-emitting element 510; the light-emitting element 510 is disposed on a support component 200 and faces the conveyor belt 100.

[0090] In the application, a mounting groove can be provided on the support plate 220 of the light-transmitting conveyor; the light-emitting element 510 can be disposed on the mounting groove. The vision inspection assembly includes an inspection lens. The inspection lens can be disposed above the support plate 220 to perform optical dimension inspection on the electrode sheets transported by the conveyor belt 100 on the support plate 220.

[0091] A third aspect of this application provides a stacking machine, including the above-described conveying system; the conveyor belt 100 in the conveying system is used to convey electrode sheets in the stacking machine.

[0092] The stacking machine is used to perform stacking operations. The conveyor belt 100 can transport the electrode sheets to the stacking platform of the stacking machine to realize the stacking of the tested electrode sheets.

[0093] The above are merely preferred embodiments of this application and are not intended to limit the present invention.
