Description

Technical Field

[0001] This utility model relates to the field of power battery technology, specifically a rolling mechanism for increasing the flange thickness of a power battery weld. Background Technology

[0002] A power battery is a device that can store electrical energy and recharge it. It is a core component of new energy vehicles and other transportation tools, mainly providing power for these devices to drive electric vehicles, electric trains, electric bicycles and other transportation tools. It also plays an important role in energy storage devices. Its main function is to convert chemical energy into electrical energy to provide the necessary power support for the device and support its normal operation. During the assembly process, it is arranged and combined linearly to form a power battery pack. During the manufacturing process, the aluminum shell and cover plate of the power battery are sealed and welded by laser technology. The weld seam is prone to bend at the weld seam position. When assembling the power battery pack, assembly deviation will occur due to the weld seam problem.

[0003] For example, prior art application number CN 210547144 U provides a rolling mechanism for the flange amount of a power battery weld, including: a linear movement module, a first rolling device, and a second rolling device. The linear movement module includes a linear guide rail, a linear driver, and a battery clamp; the first rolling device includes a support base and a rolling assembly, the rolling assembly including a rolling bearing; the second rolling device has the same structure as the first rolling device, and the first and second rolling devices are symmetrically arranged with respect to the central axis of the linear guide rail.

[0004] During use, it was found that the size of the power battery varies depending on the usage scenario. Therefore, cleaning the weld seam flange requires clamping and cleaning power batteries of different sizes and thicknesses. Based on the actual usage, we have improved the above-mentioned existing technology. Utility Model Content

The drive motor is mounted on the outer wall of the base plate.

[0014] Furthermore: the roller head includes an extension plate mounted on the top of the column, a T-block is bolted to the end of the extension plate near the base plate, and a roller is mounted on the end of the T-block via a rotating shaft.

[0015] Furthermore: the clamping assembly includes a base plate mounted on the top of the guide rail slider, the base plate having a placement groove, two sets of identical clamping blocks symmetrically mounted on the left side wall of the placement groove, the two sets of identical clamping blocks being slidably connected to the left side wall of the placement groove via support sliders, the two sets of support sliders being threadedly connected to a screw, and one end of the screw penetrating the side wall of the placement groove and connected to an adjustment knob.

[0016] Furthermore: a pull-out button is inserted into the outer right wall of the placement slot. A straight rod is connected to the end face of the pull-out button near the outer wall of the placement slot.

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0031] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0032] Please see Figure 1-4 This utility model provides a technical solution: a rolling mechanism for removing weld seam flanging in power batteries. It should be noted that during the manufacturing process of power batteries, when welding the aluminum shell to the cover plate, a noticeable weld seam flanging is easily left at the weld seam, which affects the aesthetics and also hinders the arrangement and assembly of power batteries. Therefore, the weld seam flanging is removed by rolling. The rolling mechanism includes a main body 100, including a base plate 101. A linear guide rail 105 is horizontally mounted on the top of the base plate 101, and a guide rail slider 106 is slidably connected to the left end of the linear guide rail 105. As prior art, the linear guide rail assembly is a mechanical device that achieves linear motion through rolling friction. It includes a guide rail structure made of high-hardness, high-precision steel and a slider structure containing rolling elements such as steel balls or rollers, which achieves low-friction linear motion through rolling. Its working principle and control system are prior art and will not be described in detail.

[0033] The roll forming assembly 200 includes a column 201 mounted on the top of the substrate 101, and a roll forming head 202 mounted on the top of the column 201. The roll forming assembly 200 is used to roll the weld flange amount to eliminate the weld.

[0034] The clamping assembly 300 is mounted on the top of the guide rail slider 106, and the power battery 400 is placed on the clamping assembly 300. The power battery 400 with weld seam flange is placed on the clamping assembly 300 and then sent to the rolling assembly 200 for rolling operation through the guide rail slider 106 on the linear guide rail 105.

[0035] Preferably, a support leg 102 is installed at each of the four bottom corners of the substrate 101, a switch 103 is installed on the front side wall of the substrate 101, and a housing 104 is installed on the outer right side wall of the substrate 101.

[0036] Preferably, the columns 201 are two sets with identical structures, and the two sets of columns 201 are movably mounted on the base plate 101. The top of the base plate 101 has two sets of movable slots, and movable sliders are connected within the movable slots. The two sets of movable sliders are connected by threaded rods, and one end of the threaded rods penetrates the outer wall of the base plate 101 and is connected to the power end of the drive motor 203. The drive motor 203 is mounted on the outer wall of the base plate 101. It should be noted that... (See also...) Figure 1 The drive motor 203 is connected to an external power source and is turned on by the switch 103, which drives the threaded rod to rotate. The two sets of movable sliders are connected to the threaded rod by opposite threaded tracks, so that the rotation of the threaded rod can drive the two sets of movable sliders to move closer or further apart, thereby adjusting the distance between the two sets of roller heads 202. This can adapt to the operation of removing the weld seam flange of power batteries 400 with different thicknesses.

[0037] Preferably, the roller head 202 includes an extension plate 2021 mounted on the top of the column 201. A T-block 2022 is bolted to the end of the extension plate 2021 near the base plate 101. A roller 2023 is mounted to the end of the T-block 2022 via a rotating shaft. Please refer to [link to relevant documentation]. Figure 1 and Figure 2 It should be noted that the T-block 2022 is inserted into the extension plate 2021 and fixed by bolts. It has good limiting effect and is easy to install and disassemble. The roller 2023 is made of steel. When the power battery 400 passes by, the two sets of rollers 2023 roll on the surface of the power battery 400 to squeeze the weld and clean the weld edge. It should be noted that before the roller pressing mechanism is running, those skilled in the art need to adjust the distance between the two sets of roller pressing heads 202 according to the thickness of the power battery 400. The adjustment is achieved by controlling the distance between the two sets of roller pressing heads 202 through the drive motor 203. At the same time, the control switch and control system of the drive motor 203 are existing technologies known to those skilled in the art and will not be described in detail.

[0038] Preferably, the clamping assembly 300 includes a base plate 301 mounted on top of the guide rail slider 106. A placement groove 302 is formed on the base plate 301. Two sets of identical clamping blocks 303 are symmetrically mounted on the left side wall of the placement groove 302. The two sets of identical clamping blocks 303 are slidably connected to the left side wall of the placement groove 302 via support sliders. The two sets of support sliders are threadedly connected to a screw 304, and one end of the screw 304 passes through the side wall of the placement groove 302 and is connected to an adjusting knob 305. It should be noted that the threaded tracks on the two sets of support sliders are arranged in opposite directions, so that the rotation of the threaded rod 304 can drive the two sets of support sliders to move closer and further apart. Please refer to [link to relevant documentation]. Figure 3 Rotating the adjusting knob 305 causes the two sets of clamping blocks 303 to move closer together and clamp the placed power battery 400. Rubber soft plates are adhered to the surfaces of the two sets of clamping blocks 303 clamping the power battery 400 to protect the outer shell of the power battery 400 from damage. It should be noted that the adjusting knob 305 does not need to limit or fix the position. The power battery 400 is placed horizontally in the placement slot 302, and the clamping distance is adjusted by rotating the threaded rod 304. The threaded connection itself has a certain limiting characteristic and will not be subjected to excessive external force. Therefore, the adjusting knob 305 does not need to limit or fix the position.

[0039] Preferably, a pull-out button 306 is inserted into the right outer wall of the placement slot 302. A straight rod 309 is connected to the end face of the pull-out button 306 near the outer wall of the placement slot 302. The straight rod 309 passes through the side wall of the placement slot 302 and is connected to a stop block 307. There are guide sliders on both sides of the stop block 307, and a guide groove 308 matching the guide slider is opened on the side wall of the placement slot 302. A limiting piece 310 is connected to the side of the straight rod 309 near the stop block 307, and the left outer wall of the limiting piece 310 is connected to a return spring. Once 311 is in place, and a return spring 311 is sleeved on the outer wall of the straight rod 309, a movable cavity matching the limiting piece 310 and the return spring 311 is provided in the side wall of the placement groove 302. It should be noted that both the return spring 311 and the limiting piece 310 are located in the movable cavity. The limiting piece 310 and the return spring 311 provide stress so that the abutment 307 can fit well against the side wall of the power battery 400, thereby providing a lateral limiting effect on the power battery 400. Please refer to [link / reference]. Figure 3 and Figure 4 Before inserting the power battery 400, manually pull up the pull-up button 306 to create a certain distance between the abutment block 307 and the outer wall of the power battery 400. After placing the power battery 400, release the pull-up button 306 to bring the abutment block 307 close to the outer wall of the power battery 400, providing a lateral limiting effect for the power battery 400. Together with the two sets of clamping blocks 303 mentioned above, the power battery 400 has good stability and limiting properties, which facilitates the subsequent weld cleaning work.

[0040] It should be noted that the electrical components of this utility model have already combed the wire harness during operation, so there will be no problem of wire harness tangling.

[0041] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
