Abstract
Description
Technical Field
[0001] This utility model belongs to the field of battery production equipment technology, specifically a movable module for handling stacked battery cells. Background Technology
[0002] Currently, the main production methods for lithium batteries in the industry are winding and stacking. Winding technology is relatively mature and is mainly used for cylindrical batteries and small-capacity prismatic lithium batteries. For large-capacity power lithium batteries and irregularly shaped batteries, stacking technology is required for production.
[0003] The production process requires the use of many stacked pieces, which need to be transferred to the corresponding processing position. However, current handling modules usually use a combination of motor and lead screw as the lifting component, which takes up a lot of space. If the angle of the stacked pieces also needs to be adjusted, a rotating device needs to be added to the moving end of the lead screw. This makes the handling device more cumbersome and larger, which is not conducive to the miniaturization of the equipment. Utility Model Content

Detailed Implementation
[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0028] Please refer to Figure 1-5 ;
[0029] The present invention aims to provide a smaller movable module, providing a basic solution for the future miniaturization of equipment. It should be noted that the movable module described in the present invention is a part of the conveying device and only has the functions of rotation and lifting. Therefore, in practical applications, the movable module can be connected to the moving component, and the movable end of the movable module can be connected to the alignment component or the acquisition component, etc.
[0030] Specifically, it includes a linear motor 1 and a rotary motor 2. The output end of the linear motor 1 is rotatably connected to a movable shaft 3. The movable shaft 3 passes through the rotating shaft 21 of the rotary motor 2, and the movable shaft 3 extends out of the rotating shaft 21 for connection with external components. In this embodiment, the connection method of the linear motor 1 and the rotary motor 2 is not limited. It can be achieved by connecting a frame or by stacking, etc., as long as it can be arranged vertically. In addition, the external components can be components for aligning stacked pieces, or components for acquiring stacked pieces, etc. The rotating shaft 21 and the movable shaft 3 are longitudinally slidably connected, and the rotating shaft 21 can drive the movable shaft 3 to rotate. For example, the movable shaft 3 adopts a polygonal structure and has a corresponding through hole in the rotating shaft 21. When the movable shaft 3 passes through the rotating shaft 21, it cannot rotate relative to the rotating shaft 21, but can only slide longitudinally relative to the rotating shaft 21.
[0031] During operation, the stacked pieces are placed on the external component, which can be for acquisition or alignment. At this time, the rotary motor 2 drives the movable shaft 3 to rotate, thereby adjusting the angle of the external component. Then, the movable component drives the whole to move to the corresponding operating position. After reaching the corresponding position, the linear motor 1 drives the movable shaft 3 to extend or retract, thereby adjusting the height of the stacked pieces so that they can approach the working position for subsequent operations.
[0032] In this invention, by using a linear motor 1 and a rotary motor 2 installed vertically and by using the linear motor 1 instead of the traditional lifting assembly, the overall structure is more compact. This not only saves a lot of installation space, but also makes the power transmission more direct, reduces energy loss, and greatly reduces the number of parts used. This makes it very user-friendly and convenient for future maintenance.
[0033] Preferably, the rotary motor 2 is mainly used to adjust the angle of the stacked pieces and does not need to provide a large torque. Therefore, the rotary motor 2 adopts a DD motor, which is lighter, thinner and smaller in size.
[0034] In addition, the outer casing 41 of the linear motor 1 is mounted on the outside. The end of the casing 41 is provided with a flange 42, which is used to mount the rotary motor 2. This arrangement allows the linear motor 1 and the rotary motor 2 to be closer and more compact, further reducing their size and forming an integral module. Because the overall size is relatively small, it can be replaced as a whole module when a fault occurs, which is very quick.
[0035] One embodiment of the linear motor 1 of this utility model specifically includes a stator assembly 11, in which a mover assembly 12 is provided. Both the stator assembly 11 and the mover assembly 12 adopt a cylindrical design. The stator assembly 11 consists of a fixed frame and a coil. Further, the mover assembly 12 includes a movable seat 121, on which a permanent magnet 122 and a connecting part 123 are installed. The permanent magnet 122 is installed in a ring shape on the movable seat 121 and is used in conjunction with the stator assembly 11. The connecting part 123 is installed at the center of the movable seat 121 and is rotatably connected to the movable shaft 3. Preferably, a bearing is provided at the end of the movable shaft 3, and the bearing is fixedly connected to the connecting part 123. In addition, a guide assembly is provided between the movable seat 121 and the flange 42.
[0036] The up-and-down movement of the mover assembly 12 is achieved by changing the direction of the magnetic field in the stator assembly 11. A guide assembly is also provided, which can not only guide but also limit the position of the mover assembly 12 so that it can only move longitudinally.
[0037] In this embodiment, the guide assembly includes a plurality of guide rods 1241 fixed on the bottom surface of the flange 42. The guide rods pass through the movable seat 121. The movable seat 121 is provided with a guide cylinder 1242 that cooperates with the guide rods. When moving, the guide rods can pass through the movable seat 121.
[0038] To improve functionality, the longitudinal movement of the movable shaft 3 should be adjustable. To achieve this, a grating ruler 51 is longitudinally provided on the outer side of the connecting part 123, and a bracket 52 is provided at the bottom of the flange 42. An encoder 53 is installed on the bracket 52. The encoder 53 corresponds to the grating ruler 51, and the movement of the movable shaft 3 corresponds to the scale of the grating ruler 51. After the encoder 53 obtains the scale of the grating ruler 51, it feeds it back to the system, so that the system can locate the current extension of the movable shaft 3 and can make background adjustments.
[0039] In addition, the encoder 53 and the grating ruler 51 are located inside the housing 41, which can protect them from external interference and also reuse the space, saving installation space.
[0040] The aforementioned external components are usually also operational, consisting of various electrical parts, and therefore require the connection of various cables. However, these cables are exposed on the outside, and the wiring is very complicated and cumbersome. Therefore, this utility model adopts an internal method to provide wiring channels for the cables of the external components, making the overall design simpler.
[0041] Specifically, the outer casing 41 has a wire groove 43 on one side, which extends into the outer casing 41, and a slot 44 with a downward opening is provided at the end of the wire; the connecting part 123 has a wire groove 125, and a plug-in part 126 is provided at one end of the connecting part 123, which corresponds to the slot 44, and the other end of the wire groove 125 is bent to correspond to the end of the movable shaft 3; the movable shaft 3 has a through wire groove 31, one end of which corresponds to the end of the wire groove 125. The design of the plug-in part 126 and the slot 44 can avoid the guide being exposed.
[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0043] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
