Description

Technical Field

[0001] This utility model belongs to the field of heat treatment technology, specifically relating to a heat treatment device for battery casings. Background Technology

[0002] With the rapid development of new energy vehicles, consumer electronics and energy storage systems, high-performance energy storage devices such as lithium-ion batteries have increasingly higher requirements for safety, energy density and cycle life. As a key structural component of battery modules, the battery casing not only needs to have lightweight and high-strength mechanical properties, but also needs to meet comprehensive performance requirements such as corrosion resistance. At present, aluminum alloy, stainless steel and high-strength engineering plastics are the mainstream materials for battery casings. In the manufacturing process of battery casings, heat treatment is the core link to optimize the microstructure of materials and improve mechanical properties. In the heat treatment process, heat treatment furnaces and moving devices for conveying products into the furnace are required.

[0003] For example, Chinese Patent Application Publication No. CN211972405U discloses a mobile platform for an industrial heat treatment furnace, which includes a ground track, a flatbed carriage mounted on the ground track, wheels mounted on the flatbed carriage that travel along the ground track, and a drive mechanism mounted in the middle of the bottom of the flatbed carriage that drives the flatbed carriage to move along the ground track. A layer of refractory bricks is laid on the flatbed carriage, and several rows of workpiece resting blocks are arranged parallel to each other on the refractory bricks. These workpiece resting blocks are used to hold workpieces to be processed. This device is convenient to operate when used with an industrial furnace, improving the efficiency of workpieces entering and exiting the furnace.

[0004] As described in the prior art of the aforementioned patent, although products can be fed into a heating furnace for heat treatment, only one layer of products can be placed on the moving table. If more than one layer is placed, the products will stack together, resulting in uneven heating and increasing the working time of the heating furnace. Utility Model Content

[0005] The purpose of this invention is to provide a battery casing heat treatment device that can separate products to prevent stacking and leave a certain gap between them to facilitate the flow of hot air and uniform heating.

[0006] The specific technical solution adopted in this utility model is as follows:

[0007] A battery casing heat treatment device includes a heating device for heating the battery casing. A track is laid on the ground at the outlet end of the heating device. A trolley is mounted on the track. A track three is laid on the upper surface of the trolley. A trolley two is movably mounted on the track three. A placement frame mechanism is installed on the upper end of the trolley two. The placement frame mechanism includes a bracket fixedly mounted on the upper end of the trolley two. Crossbars are provided on both sides of the bracket. Multiple sets of cantilever rods are installed on each crossbar. Multiple sets of placement pins are provided on each cantilever rod.

[0008] In a preferred embodiment, the heating device includes a furnace body, a gate is provided at the outlet end of the furnace body, a telescopic rod is connected to the upper end of the gate, the lower end of the telescopic rod is fixedly connected to the furnace body, the two sides of the gate are slidably connected to guide rods, and the two ends of the guide rods are fixedly connected to the furnace body.

[0009] In a preferred embodiment, a second track is laid at the lower interior of the furnace body. The second track is parallel to the first track, and the second track is parallel to the third track. The distance between the two tracks of the second track is equal to the distance between the two tracks of the third track.

[0010] In a preferred embodiment, the bracket has a sliding groove on both sides, and each set of crossbars has a sliding groove on its inner side. A lead screw is installed at both ends of the crossbar, and the lead screw passes through the sliding groove.

[0011] In a preferred embodiment, a second lead screw is installed at one end of the cantilever rod near the crossbar, and the second lead screw passes through the second slide groove. A locking block is fixedly installed at one end of the second lead screw near the bracket, and the locking block is engaged with the crossbar. A third slide groove is provided on the inner side of the cantilever rod.

[0012] In a preferred embodiment, a lead screw is fixedly installed at the lower end of each set of placement pins, and the lead screw passes through the slide groove.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This utility model utilizes a placement rack mechanism to place products on the rack, allowing for gaps between products to facilitate the flow of hot air and thus heat the products. This avoids uneven heating caused by products being stacked together. In addition, the placement rack mechanism allows for multiple layers of products to be placed on the rack according to actual usage, with space between each layer to prevent uneven heating caused by stacking.

[0015] This utility model allows the trolley 1 to move along track 1, which facilitates the accurate alignment of track 3 on the trolley 1 with track 2 inside the furnace.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of this utility model. However, this utility model may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0025] Secondly, 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 this utility model. The phrase "in a preferred 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 mutually excludes other embodiments.

[0026] Secondly, this utility model is described in detail with reference to the schematic diagrams. When detailing 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.

[0027] Please see the appendix Figure 1 and Figures 3 to 5 As shown, this utility model provides a battery casing heat treatment device, including a heating device 1 for heating the battery casing. A track 2 is laid on the ground at the outlet end of the heating device 1. A trolley 3 is arranged on the track 2. A track 31 is laid on the upper surface of the trolley 3. A trolley 4 is movably arranged on the track 31. A placement frame mechanism 5 is installed on the upper end of the trolley 4. The placement frame mechanism 5 includes a bracket 51 fixedly installed on the upper end of the trolley 4. A crossbar 52 is arranged on both sides of the bracket 51. Multiple sets of cantilever rods 53 are installed on each crossbar 52. Multiple sets of placement pins 54 are arranged on each cantilever rod 53.

[0028] When heat-treating the battery casing, the battery casing is first placed on the placement rack mechanism 5, with one placement pin 54 corresponding to one battery casing. After placement, the trolley 3 is pushed along the track 2 towards the heating device 1, so that the track 31 on the trolley 3 is connected to the track 2 15 in the furnace body 11 of the heating device 1. Then, the trolley 4 is pushed to carry the placement rack mechanism 5 and the products placed on the placement rack mechanism 5 into the furnace body 11 for heat treatment along the track 31 and track 2 15. After heating, the trolley is pushed out and cooled according to the corresponding heat treatment method, so that the internal structure of the battery casing meets the required requirements.

[0029] Before placing the battery casings onto the placement rack mechanism 5, the spacing between the vertical and horizontal positions of the placement pins 54 needs to be adjusted according to the dimensions of the battery casings to be placed, so that one placement pin 54 can hold one battery casing, and there is a certain gap between the casings to facilitate the flow of hot air through the gaps to heat the casings.

[0030] Please see Figure 2 As shown, the heating device 1 includes a furnace body 11, a gate 12 is provided at the outlet end of the furnace body 11, a telescopic rod 13 is connected to the upper end of the gate 12, the lower end of the telescopic rod 13 is fixedly connected to the furnace body 11, the two sides of the gate 12 are slidably connected to the guide rod 14, and the two ends of the guide rod 14 are fixedly connected to the furnace body 11.

[0031] The furnace body 11 of the heating device 1 serves as the heating site of the shell. An electric heating wire controlled by a control device is installed inside the furnace body 11. The control device is not shown in the figure and works in conjunction with the heating device 1 to meet the normal operation requirements of the heating device 1. The gate 12 serves as a sealing device for the opening of the furnace body 11. When the product enters the furnace body 11 for heating, the extension of the telescopic rod 13 drives the gate 12 to move down to seal the opening of the furnace body 11, thereby preventing the heat inside the furnace body 11 from dissipating too quickly. When the product enters or exits the furnace body 11, the retraction of the telescopic rod 13 drives the gate 12 to move up and open the opening to facilitate the entry and exit of the product. In order to ensure the stability of the movement of the gate 12, the gate 12 is slidably connected to the guide rod 14. Moreover, the telescopic rod 13 is an electric telescopic rod that can be operated and controlled by the control device.

[0032] Please see Figure 1 and Figure 3 As shown, a second track 15 is laid at the lower end of the interior of the furnace body 11. The second track 15 is parallel to the first track 2, and the second track 15 is parallel to the third track 31. The distance between the two tracks of the second track 15 is equal to the distance between the two tracks of the third track 31.

[0033] In this embodiment, the laid tracks 1 2, 2 15 and 3 31 enable the movement of trolley 1 3 and trolley 2 4 to be directional. Track 1 2 allows trolley 1 3 to move close to the heating device 1, so that track 3 31 on trolley 1 3 can be accurately aligned with track 2 15 inside the furnace body 11, making it easy for trolley 2 4 to move out of or into the furnace body 11 along track 3 31 and track 2 15.

[0034] Please see Figure 4 and Figure 5 As shown, the bracket 51 has a sliding groove 511 on both sides, and the inner side of each set of crossbars 52 has a sliding groove 522. A lead screw 521 is installed at both ends of the crossbar 52, and the lead screw 521 passes through the sliding groove 511. A lead screw 532 is installed at the end of the cantilever rod 53 near the crossbar 52, and the lead screw 532 passes through the sliding groove 522. A locking block 533 is fixedly installed at the end of the lead screw 532 near the bracket 51, and the locking block 533 is engaged with the crossbar 52. A sliding groove 531 is provided on the inner side of the cantilever rod 53. A lead screw 541 is fixedly installed at the lower end of each set of placement pins 54, and the lead screw 541 passes through the sliding groove 531.

[0035] In this embodiment, the product is placed on the placement rack mechanism 5, which allows for a certain gap between the products, facilitating the flow of hot air and thus making it easier to heat the products. This avoids uneven heating caused by products being stacked together. In addition, the placement rack mechanism 5 allows for multiple layers of products to be placed on it according to actual usage, with a certain space between each layer, preventing uneven heating caused by products being stacked together.

[0036] Preferably, when adjusting the vertical and horizontal positions of the two placement pins 54, the distance between the two placement pins 54 can be adjusted by sliding the first screw 521 at both ends of the crossbar 52 along the first groove 511 of the bracket 51. After adjustment, the pins 54 are locked by tightening the nuts on the first screw 521. The placement pins 54 on the two cantilever rods 53 can be adjusted back and forth by sliding the second screw 532 on the cantilever rod 53 within the second groove 522. The pins 54 are then locked by tightening the nuts on the second screw 532. The distance between the two placement pins 54 is adjusted by sliding the third screw 532 at the lower end of the placement pin 54. The sliding adjustment within the slide groove 531 allows for adjustment of the lateral spacing between the two placement pins 54 mounted on the same cantilever rod 53. After adjustment, the inverted placement pin 54 is placed on the placement pin 54. To prevent the housing from shaking, the external dimensions of the placement pin 54 should be the same as the internal dimensions of the housing when selecting the placement pin 54. This will allow the housing to be secured on the placement pin 54 to prevent shaking. In addition, to prevent the cantilever rod 53 from flipping on the crossbar 52, a "C"-shaped locking block 533 is provided on the inner end of the lead screw 532 to secure it on the crossbar 52 and prevent it from flipping.

[0037] The working principle of this utility model is as follows: When heat treating the battery casing, the battery casing is first placed on the placement rack mechanism 5, with one placement pin 54 corresponding to one battery casing. After placement, the trolley 3 is pushed along the track 2 towards the heating device 1, so that the track 31 on the trolley 3 is connected to the track 2 15 inside the furnace body 11 of the heating device 1. Then, the trolley 4 is pushed to carry the placement rack mechanism 5 and the products placed on the placement rack mechanism 5 into the furnace body 11 for heat treatment along the track 31 and track 2 15. After heating, the trolley is pushed out and cooled according to the corresponding heat treatment method, so that the internal structure of the battery casing meets the required requirements.

[0038] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
