[0002] A cylindrical pack automatic line refers to an automated production line that integrates components such as cylindrical lithium battery cells, battery management systems, and battery management chips to form a complete battery pack. This production line involves multiple technological processes, including cell manufacturing, cell testing, cell assembly, battery management system integration, etc. It consists of three parts: battery cell processing, module welding, and PACK assembly. Each device has an independent control system and a touch screen. The assembly section is divided into front-end automated assembly of the module and post-processing manual assembly of the module. The process from cell sticker sorting to welding is the front end, and the process from welding inspection to BMU assembly is the post-processing section of the module. Automated operations include automatic full-box feeding, automatic sticker application, barcode scanning, cell sorting, sub-assembly matching, cell insertion into the lower bracket, CCD polarity detection, etc., and can achieve automatic welding of modules with various complex processes. The whole-line control realizes automated feeding, automatic connection of the logistics of each process, and operation of the automatic drive equipment.

[0003] The structure of a conventional automatic alignment component is relatively fixed. When dealing with materials of different sizes and structures, the flexibility of its structure is relatively limited, so that it can only assist in processing materials of a certain size to dock with downstream equipment, resulting in relatively limited flexibility and applicability.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and an automatic alignment component and a cylindrical pack automatic line are proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide an automatic alignment component and a cylindrical pack automatic line to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an automatic alignment component and a cylindrical pack automatic line, including a support ring frame and a limit frame. A hydraulic push rod is vertically installed in the middle of the support ring frame, and a fixed disk is installed at the bottom of the hydraulic push rod. Moreover, an auxiliary frame is installed on the top surface of the fixed disk, and a calibration component is installed at the lower end of the side of the fixed disk. The limit frame is horizontally installed at one end of the auxiliary frame away from the fixed disk. The limit frame includes a pneumatic telescopic rod, a first electric drive joint, a second electric drive joint, and a limit arc plate. One end of the pneumatic telescopic rod is installed with the first electric drive joint, and the end of the pneumatic telescopic rod away from the first electric drive joint is installed with the second electric drive joint. Moreover, the end of the second electric drive joint away from the pneumatic telescopic rod is installed with the limit arc plate.

[0007] Furthermore, the auxiliary frames are installed in a circular array in a "cross" shape structure on the top surface of the fixed disk, and the calibration components are installed in a circular array on the side surface of the fixed disk.

[0008] Furthermore, four sets of the auxiliary frames, calibration components and limit frames are provided, and the support ring frame and the hydraulic push rod are fixedly connected to each other.

[0009] Furthermore, the auxiliary frame includes a stabilizing frame, a connecting frame and a support pile. A connecting frame is vertically connected to the bottom of the side of the stabilizing frame away from the fixed disk, and a support pile is connected to the side of the connecting frame away from the fixed disk. The first electric drive joint is installed on the side of the connecting frame close to the fixed disk.

[0010] Furthermore, both the stabilizing frame and the support pile are slidably connected to the connecting frame, and the top end of the connecting frame is fixedly connected to the support ring frame.

[0011] Furthermore, the calibration component includes a fixed pile, a movable shaft and a position sensor. A movable shaft is installed at the bottom of the fixed pile, and a position sensor is connected to one side of the movable shaft.

[0012] Furthermore, both the movable shaft and the position sensor are installed on the left and right sides of the top of the position sensor, and the fixed pile is welded to the fixed disk.

[0013] A cylindrical pack automatic line is installed with the automatic alignment component as described above.

[0014] The utility model provides an automatic alignment component and a cylindrical pack automatic line, which have the following beneficial effects:

[0015] 1. In the utility model, a first electric drive joint and a second electric drive joint are respectively installed at the left and right ends of the pneumatic telescopic rod. With the operation of the structures of the first electric drive joint and the second electric drive joint, the pneumatic telescopic rod connected to the first electric drive joint and the limit arc plate structurally connected to the second electric drive joint can swing and adjust at a certain angle in the horizontal direction with the first electric drive joint and the second electric drive joint as the centers respectively. At the same time, by using the telescopic property of the structure of the pneumatic telescopic rod itself and the operation of the above structure, on the one hand, the auxiliary frames arranged in a circular array can be flexibly adjusted according to the battery cores to be processed within a certain range of activities and limit and clamp them. On the other hand, the cooperative operation of the above structure can ensure that the battery cores limited and clamped can be positionally aligned with the device and equipment directly below, preventing deviation and unnecessary influence on processing.

[0016] 2. In this utility model, since the auxiliary frame is interconnected with the auxiliary frame through the first electric drive joint, and the top of the support pile is fixedly connected to the support ring frame, while the stabilizing frame and the connecting frame are both slidably connected to the surface of the support pile near the fixed disk, when the hydraulic push rod operates, the auxiliary frame connected to it through the fixed disk at its bottom will move up and down synchronously in the vertical direction. As a result, the stabilizing frame and the connecting frame will slide along the surface of the support pile synchronously. The use of the above structure can ensure the maximum stability of the fixed disk, the calibration component, and the limiting frame during vertical lifting and lowering adjustment. In cooperation with the operation of the calibration component, it can ensure that the limiting frame can be adjusted flexibly for alignment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following further describes in detail the embodiments of this utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate this utility model, but cannot be used to limit the scope of this utility model.

[0023] Such as Figures 1 to 4As shown in the figure, an automatic alignment component and a cylindrical pack automatic line include a support ring frame 1 and a limit frame 6. A hydraulic push rod 2 is vertically installed in the middle of the support ring frame 1, and a fixed disk 3 is installed at the bottom of the hydraulic push rod 2. Moreover, an auxiliary frame 4 is installed on the top surface of the fixed disk 3, and a calibration component 5 is installed at the lower end of the side of the fixed disk 3. The limit frame 6 is horizontally installed at one end of the auxiliary frame 4 away from the fixed disk 3. The limit frame 6 includes a pneumatic telescopic rod 601, a first electric drive joint 602, a second electric drive joint 603, and a limit arc plate 604. One end of the pneumatic telescopic rod 601 is installed with the first electric drive joint 602, and the end of the pneumatic telescopic rod 601 away from the first electric drive joint 602 is installed with the second electric drive joint 603. Moreover, the end of the second electric drive joint 603 away from the pneumatic telescopic rod 601 is installed with the limit arc plate 604. The auxiliary frame 4 is installed in a cross-shaped structure in a circular array on the top surface of the fixed disk 3, and the calibration component 5 is installed in a circular array on the side surface of the fixed disk 3. Four groups of auxiliary frames 4, calibration components 5, and limit frames 6 are provided. The support ring frame 1 and the hydraulic push rod 2 are fixedly connected to each other. With the structural operation of the first electric drive joint 602 and the second electric drive joint 603, the pneumatic telescopic rod 601 connected to the first electric drive joint 602 and the limit arc plate 604 structurally connected to the second electric drive joint 603 can swing and adjust at a certain angle in the horizontal direction with the first electric drive joint 602 and the second electric drive joint 603 as the centers respectively. At the same time, the telescopic property of the pneumatic telescopic rod 601 itself is utilized.

[0024] As Figures 1 to 4 shown in the figure, the auxiliary frame 4 includes a stable frame 401, a connecting frame 402, and a support pile 403. The bottom of the side of the stable frame 401 away from the fixed disk 3 is vertically connected to the connecting frame 402, and the side of the connecting frame 402 away from the fixed disk 3 is connected to the support pile 403. The first electric drive joint 602 is installed on the side of the connecting frame 402 close to the fixed disk 3. Both the stable frame 401 and the support pile 403 are slidably connected to the connecting frame 402, and the top end of the connecting frame 402 is fixedly connected to the support ring frame 1. The calibration component 5 includes a fixed pile 501, a movable shaft 502, and a position sensor 503. The bottom of the fixed pile 501 is installed with the movable shaft 502, and one side of the movable shaft 502 is connected to the position sensor 503. The movable shaft 502 and the position sensor 503 are both installed on the left and right sides of the top of the position sensor 503, and the fixed pile 501 is welded to the fixed disk 3. When the hydraulic push rod 2 operates, the auxiliary frame 4 connected to it through the fixed disk 3 at its bottom will move up and down synchronously in the vertical direction, so that the stable frame 401 and the connecting frame 402 will slide synchronously along the surface of the support pile 403.

[0025] A cylindrical pack automatic line is installed with the automatic alignment component as described above. By setting four groups of limit frames 6 and using the real-time distance measurement of the four groups of calibration components 5, the assembly operation of different cylindrical battery cores can be carried out within a certain range. The structures of the first electric drive joint 602 and the second electric drive joint 603 enable the middle part between them to swing left and right horizontally within a certain angle, thus ensuring the flexibility of the structure and also ensuring the function of automatically calibrating the battery cores clamped and limited, preventing unnecessary deviation during assembly and thus affecting the product quality of the battery itself.

[0026] In summary, as Figures 1 to 4 shown, when the automatic alignment component and the cylindrical pack automatic line are in use, first, under the telescopic structure of the pneumatic telescopic rod 601, the limit arc plate 604 connected to one end through the second electric drive joint 603 will be horizontally pushed to the side of the cylindrical battery core, so as to clamp and limit the cylindrical battery core by using the four groups of limit frames 6.

[0027] Then at this time, the calibration component 5 installed on the side of the fixed disk 3 by using the fixed pile 501 will operate synchronously. As the structure of the movable shaft 502 rotates, the position sensor 503 connected to it will face the device structure directly below the whole device. At the same time, under the control of the calibration system, the pneumatic telescopic rod 601, the first electric drive joint 602 and the second electric drive joint 603 will operate synchronously and coordinately, and align the clamped cylindrical battery core to the appropriate position.

[0028] After that, under the push of the hydraulic push rod 2 structure in the middle of the support ring frame 1, its bottom fixed disk 3, calibration component 5 and limit frame 6 will move vertically downward at the same time, and use the sliding connection of the stable frame 401, connecting frame 402 and support pile 403 to ensure the smoothness of the structure moving downward until the battery core is integrated with other battery structures.

[0029] The embodiments of the present invention are given for the purpose of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.
