[0002] In the production of lithium-ion batteries, adapter plates need to be welded to the top cover of the battery. In order to automate the adapter plate welding process, an adapter plate loading device is usually set up to load the adapter plate onto the welding fixture.

[0003] In the prior art, a magazine is usually used to accommodate several adapter plates arranged vertically in sequence, and a lifting mechanism is set at the bottom of the magazine. The lifting mechanism is used to lift the several adapter plates, so that the several adapter plates are moved out from the top of the magazine in sequence, and then the adapter plates are transported by a material-retrieving robot.

[0004] However, with the update and iteration of lithium battery technology, many different adapter plate products have emerged. For example, when the adapter plate is provided with a boss, two adjacent adapter plates need to be placed crosswise so that the bosses of the two adjacent adapter plates are on different sides to ensure that the adapter plate does not tilt to one side and the material retrieving robot can retrieve the material in a fixed position. In addition, a rotary cylinder needs to be set to rotate some of the adapter plates 180° to meet the installation requirements of the adapter plate. Therefore, the existing adapter plate loading device has a complex structure and cumbersome operation. The adapter plates need to be manually placed crosswise, which wastes manpower and is prone to placement errors, delaying production progress. Summary of the Invention

[0033] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0034] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0035] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0036] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0037] like Figures 1 to 4 A specific embodiment of the adapter plate loading device shown is used to load the adapter plate. The adapter plate loading device includes: a discharge structure 10 and a transfer mechanism. The discharge structure 10 is arranged in a vertical direction, and a accommodating space is formed inside the discharge structure 10. A plurality of adapter plates are stacked in the vertical direction in the accommodating space. The bottom of the discharge structure 10 is provided with a bypass port 11 and a discharge port 12 that are connected to each other. The bypass port 11 and the discharge port 12 are both connected to the accommodating space. Specifically, the bypass port 11 passes through the bottom of the discharge structure 10, and the opening of the discharge port 12 faces the side of the discharge structure 10. The transfer mechanism is located downstream of the discharge structure 10. The transfer mechanism can reach into the bypass port 11 to take the adapter plate, and drive the adapter plate to move horizontally out of the discharge port 12. The transfer mechanism is suitable for transferring the adapter plate to a predetermined welding position.

[0038] It should be noted that the avoidance opening 11 is provided to avoid interference between the transfer mechanism and the discharge structure 10, and to enable the transfer mechanism to contact smoothly with the adapter plate at the bottom.

[0039] The transfer mechanism is used to pick up materials from the bottom of the discharge structure 10. The adapter plate at the bottom of the discharge structure 10 is always in a horizontal state, which is convenient for the transfer mechanism to pick up materials. It is compatible with the loading of adapter plates of different models and shapes, and there is no need to set up an additional jacking mechanism, which simplifies the overall structure of the adapter plate loading device and makes the discharge method simple.

[0040] It's worth noting that when the adapter plate to be loaded has a boss, there's no need to cross-place two adjacent adapter plates within the discharge structure 10 of this embodiment. Even if the adapter plates within the discharge structure 10 tilt due to the boss, gravity will still keep the bottom adapter plate horizontal, allowing the transfer mechanism to retrieve the material from a fixed position. Furthermore, there's no need for an additional rotary cylinder to adjust the direction of the adapter plates. Therefore, regardless of the shape of the adapter plate, both loading and unloading are simple and convenient.

[0041] It should be noted that in the prior art, when the adapter is discharged, the adapter is ejected from the magazine by a lifting mechanism (electric cylinder), and a suction cup is used to suck the material above the magazine to remove it. In addition, in order to only remove a single adapter at a time, the prior art generally uses electric cylinder vibration, vibrator vibration, or adds a brush or air knife at the magazine outlet to prevent the adapter from being strangled due to static electricity or burrs. However, when the adapter is covered with burrs, it is difficult to prevent the adapter from being strangled by electric cylinder vibration or vibrator vibration. When the adapter is strangled due to static electricity, the excess adapter is prone to tilting or getting stuck in the magazine outlet due to the vibration of the electric cylinder or vibrator, which is likely to cause an alarm when the suction cup is used to remove the material next time. The provision of a brush also increases the probability of the suction cup vacuum alarm and is also difficult to prevent the adapter from being strangled. When using an air knife to prevent the adapter from being strangled, it is easy to blow the adapter away from the predetermined position and does not fundamentally solve the problem of the adapter being strangled.

[0042] Therefore, in this embodiment, the opening height of the discharge port 12 is set to be slightly larger than the thickness of the adapter sheet, so that one adapter sheet can be smoothly taken out from the discharge port 12 without dragging out other adapter sheets, thereby solving the problem of adapter sheet carrying.

[0043] like Figure 2 As shown, a ball-moving structure 13 is provided on the side of the discharge structure 10 . The ball-moving structure 13 is provided higher than the discharge port 12 , and the ball head of the ball-moving structure 13 extends into the accommodating space.

[0044] By providing the bead structure 13, the side of the adapter plate above the discharge port 12 can be pressed, thereby preventing the adapter plate above the adapter plate from moving when the adapter plate at the discharge port 12 discharges the material.

[0045] It is worth noting that the bead structure 13 is arranged slightly higher than the discharge port 12 , so that the bead structure 13 can abut against the side of the adapter plate arranged adjacent to the adapter plate located at the discharge port 12 .

[0046] In this embodiment, if Figure 2 As shown, the discharge structure 10 includes a base 14 and a accommodating portion 15 arranged on the base 14. There are several accommodating portions 15, and an accommodating space is formed in each accommodating portion 15. The avoidance port 11 is opened on the base 14, and the discharge port 12 is opened on the accommodating portion 15 and is arranged close to the base 14.

[0047] By providing a plurality of accommodating portions 15 , the transfer mechanism can simultaneously take a plurality of adapter plates in one material removal, thereby achieving simultaneous loading of a plurality of adapter plates.

[0048] It is worth noting that in the prior art, a battery typically requires two adapter plates: an aluminum adapter plate for the positive electrode and a copper adapter plate for the negative electrode. Therefore, in this embodiment, two receiving portions 15 are provided on the base 14, one receiving portion 15 being used to receive the aluminum adapter plate, and the other receiving portion 15 being used to receive the copper adapter plate.

[0049] For further explanation, please refer to Figure 2 The upper end of the accommodating portion 15 is opened to facilitate the placement of the adapter.

[0050] like Figure 1 、 Figure 3 and Figure 4 As shown, the adapter plate loading device also includes a mounting seat 20 and a driving structure 30. The discharge structure 10 is arranged on the mounting seat 20 and several are arranged at intervals. The driving structure 30 is suitable for driving the mounting seat 20 to move so that several discharge structures 10 correspond to the transfer mechanism respectively.

[0051] There are several discharging structures 10. When the adapter piece in one of the discharging structures 10 is used up, the driving structure 30 moves another discharging structure 10 equipped with the adapter piece to the material taking position of the transfer mechanism to ensure continuous loading of the adapter piece.

[0052] In this embodiment, if Figure 1 、 Figure 3 and Figure 4 As shown, the mounting seat 20 is a disc structure, and a plurality of discharge structures 10 are arranged on the mounting seat 20 at intervals along the circumferential direction. The driving structure 30 is a motor, which can drive the mounting seat 20 to rotate.

[0053] Of course, in other alternative embodiments, the mounting seat 20 can also be a long strip plate, and several discharge structures 10 are arranged at intervals along the extension direction of the long strip plate. The driving structure 30 is a linear driving mechanism composed of a motor and a screw rod to drive the mounting seat 20 to move in a straight line.

[0054] like Figure 1 As shown, the transfer mechanism includes a material taking structure 40, a positioning structure 50 and a transfer structure 60. The material taking structure 40 is adapted to extend into the avoidance opening 11 to suck up the adapter, and drive the adapter to be placed on the positioning structure 50 for positioning. The transfer structure 60 then transfers the adapter on the positioning structure 50 to a predetermined welding position.

[0055] The positioning structure 50 is used to perform secondary positioning on the adapter plate, thereby improving the position accuracy of the adapter plate and ensuring the accuracy of the transfer structure 60 in taking and loading materials.

[0056] In this embodiment, if Figure 3As shown, the material picking structure 40 includes a transverse driving part 41, a vertical driving part 42 and a first material suction part 43. The fixed end of the vertical driving part 42 is connected to the transverse driving part 41, and the driving end of the vertical driving part 42 is connected to the first material suction part 43. The transverse driving part 41 is suitable for driving the vertical driving part 42 to move between the discharging structure 10 and the positioning structure 50.

[0057] After the adapter piece is taken out from the discharging structure 10 by the taking structure 40 , the adapter piece is driven to move horizontally and vertically to be transported to the positioning structure 50 . The transporting method of the adapter piece is simple.

[0058] In this embodiment, both the horizontal driving portion 41 and the vertical driving portion 42 are cylinders.

[0059] Of course, the horizontal driving part 41 and the vertical driving part 42 may also be other linear driving mechanisms.

[0060] It should be noted that the aforementioned transverse direction refers to the connecting direction of the discharge structure 10 and the positioning structure 50 .

[0061] In this embodiment, if Figure 4 As shown, the positioning structure 50 includes a positioning block 51, which is provided with a positioning slot 511. The positioning structure 50 also includes a vibrator 52, which is transmission-connected to the positioning block 51. Specifically, the vibrator 52 is a high-frequency vibrator.

[0062] The vibrator 52 is used to drive the positioning block 51 to vibrate, so that the adapter piece enters the positioning groove 511 to achieve positioning. The positioning method of the adapter piece is simple.

[0063] In this embodiment, if Figure 4 As shown, the groove wall of the positioning groove 511 is tilted outward from bottom to top, which makes it easier for the adapter plate to enter the positioning groove 511.

[0064] In this embodiment, if Figure 4 As shown, the positioning groove 511 vertically penetrates the positioning block 51 , and a communication channel 512 is provided on a side of the positioning block 51 close to the discharge structure 10 . The communication channel 512 horizontally penetrates one side of the positioning block 51 and communicates with the positioning groove 511 .

[0065] It is worth noting that the horizontal driving part 41 can drive the vertical driving part 42 to enter the positioning groove 511 through the connecting channel 512, and the first suction part 43 is located above the positioning block 51. Then, the vertical driving part 42 drives the first suction part 43 to move downward, and drives the adapter plate to move downward and place it on the positioning block 51.

[0066] It should be noted that when processing and installing the discharge structure 10 and the positioning structure 50, it is only necessary to ensure the processing accuracy and assembly accuracy so that the discharge structure 10 and the positioning structure 50 are located on the same straight line. This can ensure the smooth transportation and positioning of the adapter, reduce the centering and debugging between the discharge structure 10 and the positioning structure 50, and simplify the production process.

[0067] In this embodiment, if Figure 1 As shown, the transfer structure 60 includes a linear drive module 61 and a second suction portion 62. The linear drive module 61 is suitable for driving the second suction portion 62 to move between the positioning structure 50 and the predetermined welding position to transfer the positioned adapter to the predetermined welding position.

[0068] like Figure 1 、 Figure 3 and Figure 4 As shown, the adapter sheet loading device further includes a color detection unit 70, which is disposed corresponding to the positioning structure 50. Specifically, the color detection unit 70 is a color sensor. The color sensor detects the color of the adapter sheet within the positioning groove 511 to ensure that the correct adapter sheet is used, thereby guaranteeing production quality.

[0069] It is worth noting that, corresponding to the aluminum adapter plate and the copper adapter plate, two first material suction parts 43 are provided, two positioning grooves 511 are provided, and two color sensors are also provided.

[0070] This embodiment also provides a specific implementation of a welding device, including the aforementioned adapter plate loading device. In the welding device, the adapter plate is loaded using the adapter plate loading device. The adapter plate located at the bottom of the discharge structure 10 is always in a horizontal state, which facilitates the material collection of the transfer mechanism. It is compatible with the loading of adapter plates of different models and shapes, and does not require an additional lifting mechanism, thereby simplifying the overall structure of the adapter plate loading device and simplifying the discharge method.

[0071] In this embodiment, if Figure 1 As shown, the welding equipment further comprises a welding fixture 80, and the predetermined welding position is located on the welding fixture 80. That is, the adapter is transported to the welding fixture 80 by the transport mechanism.

[0072] When using the adapter plate loading device of this embodiment to load the adapter plate, first, the vertical driving part 42 is driven by the horizontal driving part 41 to move to the bottom of the discharge structure 10, so that the first suction part 43 corresponds to the avoidance port 11, and the vertical driving part 42 drives the first suction part 43 to enter the discharge structure 10 from the avoidance port 11 and suck the adapter plate; then, the horizontal driving part 41 drives the vertical driving part 42 together with the first suction part 43 to move toward the positioning structure 50, so that the adapter plate is moved out from the discharge port 12, and is placed on the positioning block 51 under the drive of the horizontal driving part 41 and the vertical driving part 42, and under the vibration of the vibrator 52, the adapter plate enters the positioning groove 511 for positioning; finally, the linear driving module 61 drives the second suction part 62 to suck the adapter plate in the positioning groove 511, and places the adapter plate on the welding fixture 80.

[0073] According to the above description, this patent application has the following advantages:

[0074] 1. The device is compatible with the loading of adapters of different models and shapes, and does not require an additional lifting mechanism, which simplifies the overall structure of the adapter loading device and simplifies the discharge method;

[0075] 2. Design a suitable discharge port according to the thickness of the required adapter to ensure that only a single piece is discharged each time;

[0076] 3. Using high-frequency vibrators and large chamfers to ensure the correct positioning of the adapter, eliminating the need for complex cylinder or cam alignment mechanisms, optimizing the structure and reducing costs;

[0077] 4. Use machining precision to reduce the centering and debugging between the discharge structure and the positioning structure, reduce debugging work and optimize the spatial structure.

[0078] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
