Description

Technical Field

[0001] This utility model belongs to the field of battery production equipment technology, specifically a battery electrode position correction device. Background Technology

[0002] In the battery manufacturing process, a stacking machine is required to stack positive electrode sheets, separators, and negative electrode sheets to form a battery cell. Before the stacking process, the positive or negative electrode sheets need to be placed on a correction and positioning platform for correction and positioning. Existing correction structures are complex and bulky. For example, in the publicly available technical document "CN116914226B, Correction and Positioning Platform and Correction Method for Battery Electrodes," the technical solution uses the cooperation of multiple first bidirectional sliding parts, second bidirectional sliding parts, first linear drive parts, second linear drive parts, and rotary connectors. The first and second linear drive parts both use a combination of servo motors and lead screws, which is the reason for the large size of the entire platform. Furthermore, the large number of such structural parts makes maintenance very cumbersome. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0011] In a further technical solution, a detachable locking plate is provided between the first mounting base and the first movable base, and a detachable locking plate is provided between the second mounting base and the second movable base.

[0012] The beneficial effects of this utility model are:

[0013] This invention uses a linear motor as the moving device, which reduces the overall size, provides highly precise movements, eliminates the need for complex parts, makes maintenance convenient, and lowers the overall cost.

[0014] In addition, linear motor one and linear motor two are in independent modules. If one of the linear motors malfunctions, the entire module containing the linear motor can be replaced, making maintenance very convenient and enabling a quick resumption of production.

Detailed Implementation

[0019] 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.

[0020] Please refer to Figure 1-2 ;

[0021] The battery electrode position correction device of this utility model specifically includes a mounting base 11, a linear motor 12 mounted on the mounting base 11, a movable base 13 connected to the linear motor 12, a mounting base 21 detachably mounted on the movable base 13, a linear motor 22 mounted on the mounting base 21, the linear motor 22 and the linear motor 12 being distributed at 90°, a movable base 23 mounted on the linear motor 22, a DD motor 31 mounted on the movable base 23, and a connecting base 32 mounted on the output end of the DD motor 31; when position correction is required, the linear motor 12 and the linear motor 22 respectively drive the movable base 13 and the movable base 23 to move, so that the DD motor 31 can move on the plane formed by the XY axis. It is usually used in conjunction with a vision capture device. The position to be corrected will form coordinates and be sent to the controller. Then the linear motor 12 and the linear motor 22 will move on the XY axis according to the coordinates. If there is an angle adjustment, it will be achieved by rotating the DD motor 31.

[0022] Normally, the correction actions are small in magnitude. In this invention, by using a linear motor as the moving device, the overall size can be reduced, the action is very precise, there are no complicated parts, maintenance is very convenient, and the overall cost is lower.

[0023] Furthermore, the linear motor 12 and linear motor 22 of this utility model are in independent modules. That is, the mounting base 11, the movable base 13 and the linear motor 12 are in one module, and the mounting base 21, the movable base 23 and the linear motor 22 are in another module. If the linear motor 12 has a problem, the movable base 13 and the mounting base 21 can be removed and separated, and the entire module containing the linear motor 12 can be replaced. The maintenance is very convenient and production can be quickly restored. Of course, if the linear motor 22 has a problem, the DD motor 31 also needs to be removed.

[0024] Preferably, a sliding pair 14 is provided between the mounting base 11 and the movable base 13, and a sliding pair 24 is provided between the mounting base 21 and the movable base 23. The sliding pair 14 and the sliding pair 24 can not only provide support, but also make the movement smoother.

[0025] Furthermore, a through groove 26 is provided between the second mounting base 21 and the first movable base 13. Through a typical design, the friction between the second mounting base 21 and the first movable base 13 can be reduced. For easy disassembly during maintenance, this groove can usually be provided on the bottom surface of the second mounting base 21 or on the upper surface of the movable base.

[0026] In this embodiment of the utility model, the linear motor is typically composed of a magnetic track 41 and a coil. Both mounting base 11 and mounting base 2 are provided with a groove 51, in which the magnetic track 41 is installed. Both moving base 13 and moving base 23 are provided with a groove 52, in which the moving coil 42 is installed. This design can reduce the vertical space of mounting base 11 and moving base 13, and mounting base 21 and moving base 23, thereby further reducing the overall height. Preferably, the magnetic track 41 and the groove 51 are of the same length.

[0027] Linear motors generate a lot of heat during operation. Unlike servo motors and lead screws, which are external and do not accumulate heat, linear motors have limited space and are prone to heat accumulation. In this embodiment, both mounting base 11 and mounting base 21 are equipped with water channels. By using water cooling, mounting base 11 and mounting base 21 form a heat sink, transferring the heat generated by the linear motor to the mounting base and keeping the linear motor within a suitable temperature range. Of course, both mounting base 11 and mounting base 21 are equipped with connectors 53 for connecting to external water pipes.

[0028] In this embodiment of the utility model, a detachable locking plate 15 is provided between the mounting base 11 and the movable base 13, and a detachable locking plate 25 is provided between the mounting base 21 and the movable base 23. During transportation, the locking plates 15 and 25 can be installed to prevent relative movement between the two mounting bases and the two movable bases, facilitating transportation. In addition, after installation, debugging is required. For the planar movement of the XY axis, it is necessary to find the zero point position. The locking plates 15 and 25 are used to fix the two modules in place to avoid misalignment and interference with finding the zero point. After completion, the locking plates 15 and 25 are removed.

[0029] 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.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification 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 implementations that can be understood by those skilled in the art.
