[0045] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0046] A battery string consists of battery cells and welding ribbons. The welding ribbons connect multiple battery cells in series to form a battery string. The ends of the welding ribbons extend beyond the outermost battery cells to facilitate welding of the welding ribbons to busbars, connecting multiple battery strings to form a component board of a certain size. Traditional connection methods mainly use a hot press mechanism to weld the welding ribbons and busbars together. Before welding, the battery string needs to be lifted, and then the welding table and busbars need to be moved to the corresponding position. The battery string is then lowered and welding can be carried out. The overall process is relatively cumbersome, resulting in low welding efficiency. Therefore, a welding mechanism is proposed to simplify the welding process and improve welding efficiency.

[0047] like Figures 1 to 7As shown, this embodiment provides a welding mechanism, which includes a mounting member 100, a laser welding member 200, an image detection member 300, and a temperature detection member 400. The laser welding member 200 is provided on the mounting member 100 and can emit a welding laser. The welding laser is focused on the welding area and forms a welding focus. The welding part is placed in the welding area; the image detection member 300 is provided on the mounting member 100 and can capture an image of the welding part to detect the position of the welding part before welding and / or the welding state after welding; the temperature detection member 400 is provided on the mounting member 100 and is used to detect the temperature of the welding focus. In other words, the temperature detection member 400 is used to detect the temperature of the welding laser at the welding focus. In this embodiment, the welding part includes a welding strip and a busbar, and the welding focus is located at the connection between the welding strip and the busbar.

[0048] With the help of the above-mentioned structure, when welding the busbar and the welding strips at both ends of the battery string, it is only necessary to lift the battery string and then lift the busbar to the position below the battery string to perform welding. Compared with the use of a hot pressing mechanism in the prior art, the step of putting down the battery string is reduced, the welding process is simplified, and the welding efficiency is improved. In addition, through the setting of the image detection component 300, the position of the welding part before welding and / or the welding state after welding can be detected, and the position of the welding focus to be moved can be accurately determined by the position of the welding part before welding, thereby improving the welding accuracy, and timely discovering the problem of leaking or cold welding, reducing losses. The setting of the temperature detection component 400 enables the temperature of the welding focus of the laser welding part 200 to be detected at all times, so that the temperature of the welding laser during the welding process can be adjusted in time, thereby improving the welding success rate.

[0049] It should be noted that the welding mechanism also includes a controller, and the image detection component 300 includes a camera. The image detection component 300 is connected to the controller in communication and can transmit the captured image to the controller, and the controller determines the welding status of the welded part. The welding status includes whether a cold weld occurs. In other embodiments, the welding status also includes a leaky weld. The controller is connected to the temperature detection component 400 in communication, and the temperature detection component 400 sends the detected temperature of the welding focus to the controller. The controller adjusts the output power of the laser welding component 200 in real time according to the received temperature of the welding focus to ensure that the temperature of the welding focus can make the welding strip and the busbar qualified.

[0050] In other embodiments, existing optical detection systems can also be used to determine the welding status during the welding process to determine whether the welding is qualified. Specifically, during the welding process, the reflected light, visible light, and infrared light generated at the welding position are identified, and the welding status is detected through deep learning of the light source waveform.

[0051] In order to simplify the installation process and expand the applicable scenarios of welding, the welding mechanism also includes an adjustment component 500, which is arranged on the mounting part 100. The temperature detection component 400 includes an infrared temperature detection sensor, which is arranged at the output end of the adjustment component 500. The adjustment component 500 is used to adjust the detection angle and / or position of the infrared temperature detection sensor so that the infrared temperature detection sensor detects the temperature of the welding focus. The above-mentioned setting eliminates the need for the infrared temperature detection sensor to detect the position of the welding focus during the installation process, thereby reducing the difficulty of installation. In addition, it can also adapt to welding focuses of different positions generated by different laser welding parts 200 or different welding processes.

[0052] Regarding the mechanism of the adjustment assembly 500, in some embodiments, the adjustment assembly 500 includes a first adjustment member 510, a first locking member 520, a second adjustment member 530 and a second locking member 540, wherein the first adjustment member 510 is slidably arranged on the mounting member 100 along the X direction; the first locking member 520 is used to lock the first adjustment member 510 and the mounting member 100; the second adjustment member 530 is rotatable around the X direction and is arranged on the first adjustment member 510, and the infrared temperature detection sensor is arranged on the second adjustment member 530; the second locking member 540 is used to lock the second adjustment member 530 and the first adjustment member 510.

[0053] The above arrangement simplifies the structure of the adjustment assembly 500 . The detection position adjustment of the infrared temperature detection sensor can be completed by only moving the first adjustment member 510 and rotating the second adjustment member 530 , thereby simplifying the adjustment method of the infrared temperature detection sensor and improving the adjustment efficiency.

[0054] Regarding the locking method, in some embodiments, the mounting member 100 is provided with a mounting screw hole, the first adjusting member 510 is provided with a first adjusting slot 511 extending along the X-direction, and the first locking member 520 comprises a screw that passes through the first adjusting slot 511 and is screwed into the mounting screw hole. This screw connection simplifies and secures the connection between the first adjusting member 510 and the mounting member 100.

[0055] To improve the smoothness of movement of the first adjusting member 510 and prevent deviation during movement, in some embodiments, at least two mounting screw holes, at least two first adjusting slots 511, and at least two first locking members 520 are provided. The first adjusting slots 511 are spaced apart along the Y direction, and the first locking members 520 pass through corresponding first adjusting slots 511 and are screwed into corresponding mounting screw holes. The Y direction and the X direction are perpendicular to each other.

[0056] The mounting member 100 is provided with a fixing portion 110, which is provided with a fixing screw hole extending through the fixing portion 110 in the X direction. The adjustment assembly 500 includes an adjustment screw 550, which is threaded into the fixing screw hole and has one end extending through the fixing screw hole and connected to the first adjustment member 510. This arrangement allows the distance between the first adjustment member 510 and the fixing portion 110 to be adjusted while the adjustment screw 550 is being tightened, thereby improving adjustment accuracy.

[0057] To prevent the adjusting screw 550 from rotating after being disturbed, thereby affecting the adjustment accuracy, in some embodiments, the adjustment assembly 500 includes an adjusting nut 120. The adjusting screw 550 is threadedly connected to both the adjusting nut 120 and the fixing screw hole. When the adjusting nut 120 abuts the fixing portion 110, the adjusting screw 550 is locked. This arrangement allows the adjusting screw 550 to be locked by the adjusting nut and the fixing portion 110, thereby preventing the adjusting screw 550 from further rotation after being locked. The first adjusting member 510 is then locked to the mounting member 100 via the first locking member 520.

[0058] Because the first adjusting member 510 is slidably mounted on the mounting member 100 along the X-direction, in some embodiments, the first adjusting member 510 is provided with an adjusting screw hole, into which the adjusting screw 550 is threaded. This arrangement allows the first adjusting member 510 to be moved closer to or further away from the fixing portion 110 by turning the adjusting screw 550 forward and backward, thereby simplifying the adjustment process of the first adjusting member 510 and improving adjustment efficiency.

[0059] In some embodiments, one of the first adjusting member 510 and the second adjusting member 530 is provided with a first rotating portion and the other with a second rotating portion, and the first rotating portion and the second rotating portion are rotatably engaged with each other; the first adjusting member 510 is provided with a locking screw hole 512, which is located on one side of the first rotating portion, and the second adjusting member 530 is provided with an arcuate slot 531; the second locking member 540 includes a screw, which passes through the arcuate slot 531 and is screwed into the locking screw hole 512. This arrangement ensures that the second adjusting member 530 can rotate relative to the first adjusting member 510, and the second locking member 540 can be used to lock the second adjusting member 530 to the first adjusting member 510. When in use, the second locking piece 540 is screwed into the locking screw hole 512, and there is a gap between the nut of the second locking piece 540 and the second adjusting piece 530. Then the second adjusting piece 530 is rotated so that the second adjusting piece 530 rotates around the X direction relative to the first adjusting piece 510 through the first rotating part and the second rotating part. When the second adjusting piece 530 is adjusted to a position where the temperature detection piece 400 can detect the focus of the inverted welding, the rotation of the second adjustment is stopped, and then the second locking piece 540 is tightened so that the nut of the second adjusting piece 530 presses the second adjusting piece 530 against the first adjusting piece 510.

[0060] Furthermore, the first rotating portion includes an elongated hole 513 extending in the Z direction, provided on the first adjusting member 510. The second rotating portion includes a sliding rod 532 provided on the second adjusting member 530. The sliding rod 532 is inserted into the elongated hole 513 and can slide in the Z direction and rotate in the X direction within the elongated hole 513. At least two locking screw holes 512 are provided at intervals along the Z direction. The first locking member 520 passes through the arcuate slot 531 and is screwed into one of the locking screw holes 512. The Z direction, the Y direction, and the X direction are mutually perpendicular. This setting enables the second adjusting member 530 to move in the Z direction relative to the first adjusting member 510, thereby reducing the distance between the detection end of the temperature detecting member 400 and the welding focus, thereby improving the accuracy of the detection; in addition, the second adjusting member 530 and the first adjusting member 510 can achieve relative rotation through the cooperation of the sliding rod 532 and the long hole 513, so that after the second adjusting member 530 is raised or lowered relative to the first adjusting member 510, it can be ensured that the detection light emitted by the temperature detecting member 400 intersects with the welding focus; finally, through the above setting, the temperature detecting member 400 can be raised or lowered to adapt to welding parts in different positions, and can maintain a safe distance from welding parts of different models or different positions to avoid collision with welding parts, thereby improving safety of use.

[0061] In order to improve the stability of the connection between the second adjusting member 530 and the first adjusting member 510, in some embodiments, two second locking members 540 are provided, two arc-shaped grooves 531 are provided and are separated on both sides of the sliding block, the openings of the two arc-shaped grooves 531 are arranged opposite to each other, and locking screw holes 512 are provided on both sides of the long hole 513 along the Y direction.

The horizontal adjustment portion 514 is located on the upper side of the adjustment base 140 , and the vertical adjustment portion 515 is located on the front side of the adjustment base 140 .

[0064] The second adjusting member 530 is plate-shaped and disposed parallel to the vertical adjusting portion 515. The second adjusting member 530 is provided with an observation hole 533 extending along the Z direction. A sliding rod 532 is disposed above the observation hole 533. In the Y direction, the observation hole 533 is wider than the elongated hole 513.

[0065] Two fixed blocks 534 are installed on the second adjusting member 530, and each fixed block 534 is provided with a accommodating groove. The two accommodating grooves are arranged opposite to each other and form an accommodating channel. The temperature detecting member 400 is arranged in the accommodating channel. One of the fixed blocks 534 is provided with a connecting light hole at one end away from the second adjusting member 530, and the other fixed block 534 is provided with a connecting screw hole at one end away from the second adjusting member 530. The connecting screw passes through the connecting light hole and is screwed into the connecting screw hole to shrink the gap between the two fixed blocks 534 at one end away from the second adjusting member 530 and clamp the temperature detecting member 400 located in the accommodating channel.

[0066] In some embodiments, the welding mechanism includes a moving assembly 600, the mounting member 100 is disposed at the output end of the moving assembly 600, and the moving assembly 600 is used to drive the mounting member 100 to move in the Y direction and / or the Z direction. Specifically, the moving assembly 600 includes a transverse moving module 610, a fixed plate 630, and a vertical moving module 620. The fixed plate 630 is disposed at the output end of the transverse moving module 610, and the transverse moving module 610 is used to drive the fixed plate 630 to move in the Y direction.
