[0002] Lithium battery electrodes need to go through coating and drying processes during the production process. In the existing drying technology, the length of the oven unit is generally up to 80 meters, the path is remote, and the electrodes are prone to breakage inside the oven.

[0003] When the electrode tape breaks in the oven, it is necessary to rethread the tape so that the electrode can pass through the oven completely. Currently, it is usually necessary to stop the machine and use manual threading or use steel wire threading, chains, and traction belts to assist threading, but these all require complex structures to meet functional requirements. At the same time, due to the long length and high temperature of the oven, when threading the electrode tape, it is sometimes necessary to wait for the oven to cool down before threading, which is time-consuming. In addition, the oven structure is complex and inconvenient for personnel to operate. Summary of the Invention

[0048] The present invention will be further described in detail below through specific implementation examples in conjunction with the accompanying drawings.

[0049] Specific structure such as Figures 1 to 12 shown.

[0050] This embodiment provides a drone automatic belt threading device for a coating line, which includes a coating unit 1, an oven unit 2 and a correction unit 3 arranged in sequence. The drone automatic belt threading device includes: a starting landing platform 4, an end landing platform 5 and a drone component 6; the starting landing platform 4 is arranged at the substrate outlet end of the coating unit 1, and the end landing platform 5 is arranged at the substrate inlet end of the correction unit 3; the drone component 6 can fly back and forth between the starting landing platform 4 and the end landing platform 5, and is used to drive the substrate belt head 7 at the substrate outlet end of the coating unit 1 through the substrate inlet and substrate outlet of the oven unit 2 to the substrate inlet end of the correction unit 3.

[0051] In this embodiment, the coating unit 1 is unwound and the substrate tape head 7 is led to the starting landing platform 4, the substrate tape head 7 is connected to the drone component 6 on the starting landing platform 4, and then the drone component 6 is started. The drone component 6 will fly according to the programmed path adapted to the form of the oven unit 2, enter the oven unit 2 from the substrate tape inlet of the oven unit 2, fly out from the substrate tape outlet and land on the terminal landing platform 5, thus passing through the interior of the oven unit 2, and then the drone component 6 is closed, the substrate tape head 7 is removed and sent to the correction unit 3 to complete the threading work. Compared with the existing manual threading or the use of steel wire, chain, and traction belt to assist threading, the use of a drone automatic threading device makes it unnecessary to install chain guides, tensioning sprockets, and guide structures inside the oven unit 2, saving the internal space of the oven unit 2 and the cost of parts, and taking up little space, which is convenient for installation. The flight path of the drone component 6 can be controlled by programming and can adapt to oven units 2 of different lengths and different layout forms. The drone component 6 is light in weight and easy to move and place. Therefore, the drone component 6 can be moved and placed between multiple devices for universal use and has strong applicability. At the same time, there is no need to open the oven door to thread the belt, reducing heat loss in the oven 14.

[0052] In this embodiment, the substrate inlet of the oven unit 2 corresponds to the substrate outlet of the coating unit 1 , and the substrate outlet of the oven unit 2 corresponds to the substrate inlet of the correcting unit 3 .

[0053] In this embodiment, the oven unit 2 includes a plurality of ovens 14 connected end to end. The oven 14 includes a box body 15, an upper air chamber 16, a lower air chamber 17, an air nozzle assembly 18, an air chamber lifting mechanism 19 and an insulation layer 20. The side of the box body 15 is provided with an oven door, and both ends of the box body 15 are respectively provided with a substrate inlet and a substrate outlet. The box body 15 is provided with an insulation layer 20. The upper air chamber 16 and the lower air chamber 17 are relatively arranged in the box body 15. The upper air chamber 16 and The opposite sides of the lower air chamber 17 are provided with air nozzle assemblies 18, and the air nozzle assembly 18 located on the upper air chamber 16 and the air nozzle assembly 18 located on the lower air chamber 17 are staggered in sequence. The air chamber lifting mechanism 19 is provided on the box body 15, and the output end of the air chamber lifting mechanism 19 is connected to the upper air chamber 16, which is used to drive the upper air chamber 16 to move toward or away from the lower air chamber 17, and multiple air chamber lifting mechanisms 19 can be provided to improve the stability when driving the upper air chamber 16 to move.

[0054] In this embodiment, before the coating process is started, the air chamber lifting mechanism 19 is activated to lift the upper air chamber 16, thereby reserving a flight space between the upper air chamber 16 and the lower air chamber 17 for the drone assembly 6 to pass through, facilitating the drone assembly 6 to carry the substrate tape head 7 through the oven unit 2. During the coating process, the drone assembly 6 stays on the terminal landing platform 5. When the next tape threading operation is required, the drone assembly 6 flies through the flight space of the oven unit 2 to the starting landing platform 4 to perform the next tape threading operation.

[0055] It should be noted that when the drone assembly 6 does not carry the substrate lead 7, it can also fly along a specific path outside the oven unit 2 to reduce the probability of accidents caused by the complex environment inside the oven 14.

[0056] In this embodiment, the oven unit 2 is straight or arc-shaped. Since the drone assembly 6 flies into the oven unit 2 according to the path programmed by the predetermined programming system, a specific flight path needs to be set according to the shape of the oven unit 2. When the oven unit 2 is straight, the path equation is Y=H. When the oven unit 2 is arc-shaped, the path equation is x=H. 2 +y 2 =R 2 According to the overall layout of the oven unit 2, the function path is determined and then the flight is executed.

[0057] In an optional technical solution of this embodiment, both the starting landing platform 4 and the ending landing platform 5 are provided with positioning grooves 8 , which are used to carry the drone assembly 6 .

[0058] In this embodiment, when the drone component 6 falls on the positioning groove 8, it can be stuck in the positioning groove 8, ensuring the accuracy of the landing point of the drone component 6. When the drone component 6 falls in the positioning groove 8, it is the zero point position of the drone component 6, that is, the positioning groove 8 is used for the zero point positioning of the drone component 6, ensuring the accuracy and reliability of the drone component 6 when working.

[0059] In the optional technical solution of this embodiment, a spare landing platform is further included, which is arranged on the top of the oven unit 2. The spare landing platform is used to park the drone assembly 6 when the coating line is running stably for a long time.

[0060] In an optional technical solution of this embodiment, the starting landing platform 4 is located at the centerline of the substrate exit end of the coating unit 1; the ending landing platform 5 is located at the centerline of the substrate inlet end of the correction unit 3. This ensures that the drone assembly 6 is centered on the centerline of the coating line to prevent substrate deviation during threading.

[0061] In an optional technical solution of this embodiment, the starting lifting and landing platform 4 is located below the port of the substrate outlet end of the coating unit 1; the ending lifting and landing platform 5 is located below the port of the substrate inlet end of the correction unit 3.

[0062] In this embodiment, when the coating line is working, the substrate passes over the starting landing platform 4 and the end landing platform 5. Regardless of whether the drone component 6 lands on the starting landing platform 4 or the end landing platform 5, it can ensure that the substrate passes over the drone component 6, avoiding the drone component 6 affecting the operation of the substrate.

[0063] In an optional technical solution of this embodiment, the flight speed of the drone assembly 6 is less than the tape travel speed of the coating unit 1 along the direction from the starting landing platform 4 to the ending landing platform 5. This maintains the substrate slack during the tape threading process, preventing relative speed during the automatic tape threading process, which could cause the substrate to break. However, this is not limiting; the flight speed of the drone assembly 6 along the direction from the starting landing platform 4 to the ending landing platform 5 could also be equal to the tape travel speed of the coating unit 1.

[0064] The optional technical solution of this embodiment also includes a platform fixing bracket 9; the starting lifting and landing platform 4 is connected to the end plate of the substrate outlet end of the coating unit 1 through the platform fixing bracket 9; and / or; the end lifting and landing platform 5 is connected to the end plate of the substrate inlet end of the correction unit 3 through the platform fixing bracket 9.

[0065] In this embodiment, the starting point landing platform 4 and the terminal landing platform 5 are respectively fixed by fixing brackets, which has a simple structure, is easy to install and has a stable structure.

[0066] However, the present invention is not limited thereto. The starting lifting platform 4 may be directly fixed to the end plate of the substrate outlet end of the coating unit 1 , and the ending lifting platform 5 may be directly fixed to the end plate of the substrate inlet end of the correction unit 3 .

[0067] In the optional technical solution of this embodiment, the drone component 6 includes a drone body 10, a clamping mechanism and a pair of landing and fixing frames 11; the pair of landing and fixing frames 11 are arranged at the bottom of the drone body 10 and are in an eight-shaped shape; the clamping mechanism is used to clamp the substrate head 7.

[0068] In this embodiment, the drone body 10 is equipped with hardware of a real-time operating system, which is responsible for the functions of flight attitude control and path execution. A pair of landing and taking-off brackets 11 can stably ensure the landing of the drone body 10. At the same time, the pair of landing and taking-off brackets 11 are in an eight-shaped shape, which is conveniently stuck in the positioning groove 8. The substrate tape head 7 is clamped by the clamping mechanism, and is stably connected to the substrate tape head 7 to prevent the substrate tape head 7 from falling off when threading.

[0069] In the optional technical solution of this embodiment, the clamping mechanism includes a lead platform 12 and a quick-release clamping plate 13; the lead platform 12 is connected between a pair of lifting and landing fixed frames 11; the quick-release clamping plate 13 is arranged on the lead platform 12, and a substrate clamping space is formed between the quick-release clamping plate 13 and the lead platform 12. After the substrate tape head 7 is inserted into the substrate clamping space, the quick-release clamping plate 13 can be locked to the lead platform 12 by screwing the nut on the quick-release clamping plate 13, so that the quick-release clamping plate 13 clamps the substrate tape head 7 between the quick-release clamping plate 13 and the lead platform 12. When the substrate tape head 7 needs to be removed, it is only necessary to screw the nut on the quick-release clamping plate 13 to loosen the substrate tape head 7 clamped between the quick-release clamping plate 13 and the lead platform 12 for removal. The clamping mechanism has a simple structure, and the provision of the lead platform 12 can prevent the substrate tape head 7 from wrinkling or deformation.

[0070] This embodiment is not limited thereto, and the clamping mechanism may also be a clip, a clamping claw, or other clamps, as long as it can meet the requirement of clamping the substrate head 7 .

[0071] This embodiment is not limited to this. The drone assembly 6 also includes a drone body 10, a hook mechanism, and a pair of landing brackets 11. The pair of landing brackets 11 are disposed at the bottom of the drone body 10 in a figure-eight shape. The hook mechanism is used to hook onto the substrate tape head 7. It should be noted that in this case, the substrate tape head 7 needs to be provided with a hole that cooperates with the hook mechanism or other structure that facilitates the hook mechanism to hook onto it. This also ensures a stable connection with the substrate tape head 7 and prevents the substrate tape head 7 from falling off during threading.

[0072] The present embodiment provides a coating line, comprising a coating unit 1, an oven unit 2, a correction unit 3 and the above-mentioned automatic belt threading device for drones arranged in sequence. Therefore, the technical advantages and effects achieved by the coating line include the technical advantages and effects achieved by the above-mentioned automatic belt threading device for drones, which will not be repeated here.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
