[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0024] This utility model embodiment provides, as follows: Figures 1 to 4 As shown, this utility model provides a specific embodiment of a punching device.
[0025] A punching device for punching holes in powder in a bowl, reference Figure 1 The punching device includes a punching plate 100, a pull rod 200, a bracket 300, and an elastic element 400. The punching plate 100 is fixedly connected to the pull rod 200. One end of the pull rod 200 is used for gripping, and the other end of the pull rod 200 is rotatably connected to the bracket 300. One end of the elastic element 400 is connected to the bracket 300, and the other end of the elastic element 400 is connected to the pull rod 200. When one end of the pull rod 200 is pressed by an external force, the pull rod 200 can drive the punching plate 100 to move downward to insert into the powder in the container. When the external force is released, the pull rod 200 can be reset under the action of the elastic force of the elastic element 400, so as to drive the punching plate 100 to move upward to the initial position.
[0026] Specifically, in the primary synthesis and sintering process of positive electrode materials for lithium batteries, when the positive electrode material powder is loaded into the sagger for sintering, a punching device is needed to punch holes in the sagger containing the positive electrode material powder to allow oxygen in the air to better enter the powder, thereby improving sintering efficiency and effect and making the material more stable. Furthermore, the punching device can be used not only for punching holes in the saggers of lithium battery positive electrode materials, but also for punching holes in other types of powders.
[0027] The punching plate 100 in the punching device is used for punching holes in the powder. The pull rod 200, bracket 300 and elastic element 400 in the punching device are used for transmission to drive the punching plate 100 to perform punching and resetting actions. The punching plate 100 is fixed on the pull rod 200. One end of the pull rod 200 is used by the worker to hold it for pressing down. The other end of the pull rod 200 is rotatably connected to the bracket 300. One end of the elastic element 400 is fixed to the pull rod 200 and the other end of the elastic element 400 is fixed to the bracket 300. The fixed connection point between the elastic element 400 and the bracket 300 is higher than the rotatable connection point between the pull rod 200 and the bracket 300.
[0028] When the worker holds one end of the pull rod 200 and presses it down, the pull rod 200 can drive the punch plate 100 to move downward and insert the punch plate 100 into the bowl of powder to achieve punching of the bowl of powder; after the punching is completed, the worker releases his hand, and one end of the pull rod 200 moves upward under the action of the elastic element 400, thereby pulling the punch plate 100 back to the initial position after the punching is pressed down to achieve reset.
[0029] The dimensions of the perforating plate 100 can be determined based on the dimensions of the powder to be perforated and the dimensions of the sagger.
[0030] Existing drilling processes typically involve manually picking up the drilling plate 100 and pressing it onto the material to make holes; this process is not only labor-intensive but also makes it difficult to maintain consistent drilling, increasing the workload for workers.
[0031] In this embodiment, a drilling device is designed, including a drilling plate 100, a pull rod 200, a bracket 300, and an elastic element 400. The drilling plate 100 is fixedly connected to the pull rod 200. One end of the pull rod 200 is used for gripping, and the other end of the pull rod 200 is rotatably connected to the bracket 300. One end of the elastic element 400 is connected to the bracket 300, and the other end of the elastic element 400 is connected to the pull rod 200. When one end of the pull rod 200 is pressed by an external force, the pull rod 200 can drive the drilling plate 100 to move downward to insert into the bowl of powder. When the external force is released, the pull rod 200 can be reset under the rebound force of the elastic element 400 to drive the drilling plate 100 to move upward to the initial position. By setting the pull rod 200, the bracket 300, and the elastic element 400 as a transmission, the drilling operation of the bowl of powder is made easier and faster, which not only reduces the labor intensity of workers, but also effectively avoids misoperation and improves drilling efficiency and consistency.
[0032] In one embodiment, reference Figure 1 and Figure 2The perforating plate 100 includes a connecting rod 110, a mounting plate 120, and a plurality of perforating posts 130. The plurality of perforating posts 130 are all disposed on one side of the mounting plate 120. The side of the mounting plate 120 facing away from the perforating posts 130 is fixed to one end of the connecting rod 110. The other end of the connecting rod 110 is connected to the pull rod 200. The plurality of perforating posts 130 are evenly distributed on one side of the mounting plate 120 for insertion into the bowled powder. The mounting plate 120 and the connecting rod 110 can be integrally formed. When one end of the pull rod 200 is pressed, the pull rod 200 drives the perforating plate 100 to move downward and causes the plurality of perforating posts 130 to be inserted into the bowled powder, thereby realizing the perforation of the bowled powder.
[0033] In one embodiment, reference Figure 3 The drilling device also includes a base 500, a bracket 300 mounted on the base 500, and a sagger placement area 510 on the base 500, which is located directly below the drilling plate 100. The base 500 is placed on a workbench or the ground for mounting the bracket 300 and placing the saggered powder. When drilling the saggered powder, the saggered powder to be drilled is first placed in the sagger placement area 510. Then, one end of the pull rod 200 is pulled, causing the pull rod 200 to move the drilling plate 100 downwards, and causing multiple drilling pins 130 to be inserted into the saggered powder to be drilled, thereby achieving drilling.
[0034] The base 500 can also be connected to the conveyor mechanism for conveying the powder in the sagger, and the sagger placement area 510 is aligned with the conveyor belt of the powder in the sagger. The powder in the sagger is then conveyed to the sagger placement area 510 by the conveyor belt of the conveyor mechanism, so that the drilling process is more convenient and faster.
[0035] In one embodiment, a sagger limiting structure is provided on the outer periphery of the sagger placement area 510 to limit the saggered powder in the sagger placement area 510; the sagger limiting structure can be a limiting post or a limiting plate to limit the saggered powder in the sagger placement area 510 to prevent the saggered powder from shifting during the drilling process, thereby affecting the drilling effect.
[0036] In one embodiment, reference Figure 3The drilling device also includes a limiting rod 600. One end of the limiting rod 600 is fixed to the pull rod 200, and the other end of the limiting rod 600 can abut against the base 500 when the drilling plate 100 is inserted into the powder at a preset depth. The limiting rod 600 is used for drilling limitation. The length of the limiting rod 600 is determined according to the height of the powder in the bowl and the preset drilling depth. When one end of the pull rod 200 is pulled, the pull rod 200 moves the drilling plate 100 downward and the multiple drilling pins 130 are inserted into the preset depth of the powder to be drilled. At this time, the other end of the limiting rod 600 abuts against the base 500, so that the pull rod 200 cannot continue to move downward, thereby maintaining the current drilling depth.
[0037] In one embodiment, reference Figure 1 and Figure 2 The tie rod 200 and the bracket 300 are rotatably connected by the bearing 310. The connection by the bearing 310 can reduce the friction between the end of the tie rod 200 and the bracket 300 to improve operating efficiency. The bearing 310 can also provide support and positioning, and can also reduce vibration during rotation to improve the stability and comfort of the equipment.
[0038] In one embodiment, reference Figure 1 and Figure 4 The pull rod 200 includes a first rod segment 210 and a second rod segment 220. An angle θ is formed between the first rod segment 210 and the second rod segment 220. The end of the second rod segment 220 is connected to the bracket 300. The perforated plate 100 is connected to the first rod segment 210, and the elastic element 400 is connected to the second rod segment 220. By setting a certain angle θ between the first rod segment 210 connected to the perforated plate 100 and the second rod segment 220 connected to the elastic element 400, the pull rod 200 can be more balanced under the gravity of the perforated plate 100 and the elastic force of the elastic element 400.
[0039] In one embodiment, the elastic element 400 can be a spring, which can provide support force in the initial state and provide restoring force after drilling is completed. The spring can be a rubber spring, which can not only effectively dampen shocks but also absorb impacts, making the entire operation process more stable.
[0040] In one embodiment, the potted powder is a battery positive electrode material. The lithium battery manufacturing process includes the production of positive electrode materials, which involves mixing positive electrode active materials, conductive agents, binders, and other raw materials together, and then loading the mixed raw materials into a pot for high-temperature sintering. During the high-temperature sintering process, a punching device is used to punch holes in the positive electrode material in the pot, allowing oxygen to better enter the interior of the potted powder, making the potted powder heat up faster and more evenly, thereby improving sintering efficiency and effect.
