Description

Technical Field

[0001] The present application relates to the technical field of battery production, and in particular to a safety protection component for a batching inlet of a lithium-ion battery production. Background Art

[0002] Lithium-ion batteries are rechargeable batteries widely used in portable electronic devices, electric vehicles and home energy storage systems. They are one of the most popular battery technologies due to their high energy density, long life and no memory effect. The basic components of lithium-ion batteries include positive electrode materials, negative electrode materials, electrolytes and separators. During the charging and discharging process, lithium ions move between the positive and negative electrodes through the electrolyte. When charging, lithium ions move from the positive electrode to the negative electrode and embed into the negative electrode material; when discharging, lithium ions move from the negative electrode back to the positive electrode and release electrical energy.

[0003] When lithium-ion batteries are produced, ingredients need to be added from the feeding port. During the operation of the staff, if the cover cylinder fails, it will suddenly drop, posing the risk of crushing the hands of personnel. Therefore, in order to solve the above problem, the present application provides a safety protection component for the feeding port of lithium-ion battery production ingredients.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0005] In order to solve the problem that a cylinder failure cover plate may cause injury to workers, the present application provides a lithium-ion battery production batching feed port safety protection component.

[0006] The present application provides a safety protection component for a lithium-ion battery production batching port, wherein a batching barrel is used for battery batching, a support plate is fixedly arranged above the batching barrel, an upper cover plate is arranged above the support plate, the support plate is connected to the upper cover plate through two cylinders, a support rod is arranged on the upper wall of the support plate and can be rotated to enter between the support plate and the upper cover plate, and when the cylinder fails, the support rod supports the upper cover plate.

[0007] Preferably, a plurality of rotating shafts are fixedly provided on the upper wall of the supporting plate, and the upper ends of the rotating shafts are rotatably connected to rotating plates.

[0008] Preferably, a support rod is fixedly provided on one end of the rotating plate away from the rotating shaft, and the height of the support rod is greater than the width of a human palm.

[0009] Preferably, the side walls of the rotating plate are fixedly connected with fixing rods.

[0010] Preferably, a plurality of sliding blocks are provided through and slidably connected to the upper wall of the supporting plate, and the number of the sliding blocks is the same as that of the rotating plate.

[0011] Preferably, the sliding block cooperates with the rotating plate closest to it, and the rotating plate rotates to abut against the sliding block and make it slide.

[0012] Preferably, the upper end of the sliding block is an inclined surface and the bottom end of the inclined surface is arranged away from the center of the supporting plate. In a natural state, the bottom end of the inclined surface of the sliding block is flush with the upper end of the supporting plate.

[0013] Preferably, a fixed block is fixedly connected to the lower end of the sliding block, and the fixed block is elastically connected to the supporting plate via a spring.

[0014] Preferably, a lower fixing ring is fixedly provided on the upper wall of the support plate, and an upper fixing ring is fixedly provided on the lower wall of the upper cover plate.

[0015] Preferably, the lower fixing ring, the upper fixing ring and the cylinder cooperate to open and close the batching barrel.

[0016] In summary, this application includes the following beneficial technical effects:

[0017] By pulling the fixed rod, the rotating plate rotates, driving the support rod to enter between the supporting plate and the upper cover. Compared with the traditional method of relying solely on the cylinder to move the upper cover, when the cylinder fails, the support rod located under the upper cover can effectively support the upper cover, protecting the workers' palms from being crushed and improving the safety of the production process.

[0018] The sliding block is forced downward by rotating the rotating plate. When the rotating plate completely passes through the sliding block, the sliding block moves upward due to the action of the spring, so that the support rod is always located under the upper cover plate, reducing the possibility of the support rod rotating out from under the upper cover plate due to collision during operation, thereby improving production safety.

DETAILED DESCRIPTION

[0023] The following is combined with Figure 1-3 This application is described in further detail.

[0024] Embodiment 1

[0025] Reference Figure 1-3 A safety protection component for a lithium-ion battery production batching port, a batching barrel 1 is used for battery batching, a support plate 2 is fixedly arranged above the batching barrel 1, an upper cover plate 4 is arranged above the support plate 2, the support plate 2 is connected to the upper cover plate 4 through two cylinders 6, a lower fixing ring 3 is fixedly arranged on the upper wall of the support plate 2, and an upper fixing ring 5 is fixedly arranged on the lower wall of the upper cover plate 4. The lower fixing ring 3, the upper fixing ring 5 and the cylinder 6 work together to open and close the batching barrel 1, and the lower fixing ring 3 and the upper fixing ring 5 can be connected by sliding.

[0026] The upper wall of the supporting plate 2 is provided with a supporting rod 9 which can be rotated to enter between the supporting plate 2 and the upper cover plate 4. When the cylinder 6 fails, the supporting rod 9 supports the upper cover plate 4.

[0027] Several rotating shafts 7 are fixedly arranged on the upper wall of the supporting plate 2, and the upper ends of the rotating shafts 7 are rotatably connected to the rotating plates 8. The ends of the rotating plates 8 away from the rotating shafts 7 are fixedly arranged with support rods 9, and the height of the support rods 9 is greater than the width of a human palm, and the height of the support rods 9 is greater than the distance between the supporting plate 2 and the upper cover plate 4 when the batching barrel 1 is closed. This arrangement effectively realizes that the support rods 9 support the upper cover plate 4 when it falls, thereby protecting the safety of the workers. The side walls of the rotating plate 8 are fixedly connected with fixed rods 10.

[0028] A plurality of sliding blocks 11 are provided through the upper wall of the support plate 2 and are slidably connected thereto, and the number of the sliding blocks 11 is the same as that of the rotating plate 8. The sliding block 11 cooperates with the rotating plate 8 closest thereto, and the rotating plate 8 rotates to press against the sliding block 11 and make it slide. The upper end of the sliding block 11 is an inclined surface, and the bottom end of the inclined surface is arranged away from the center of the support plate 2. In the natural state, the bottom end of the inclined surface of the sliding block 11 is flush with the upper end of the support plate 2. The lower end of the sliding block 11 is fixedly connected to a fixed block 12, and the fixed block 12 is elastically connected to the support plate 2 through a spring 13. The rotation of the rotating plate 8 will squeeze the sliding block 11 to slide downward, and when the rotating plate 8 completely passes through the sliding block 11, the sliding block 11 will move upward due to the action of the spring 13. During the production process, the support rod 9 may rotate out from under the upper cover plate 4 due to factors such as friction, and the sliding block 11 cooperates with the cylinder 6 to ensure that the support rod 9 is always under the upper cover plate 4.

[0029] In the actual production process, the fixed rod 10 is pulled to rotate the rotating plate 8, driving the support rod 9 to enter between the supporting plate 2 and the upper cover plate 4. During the rotation of the rotating plate 8, the sliding block 11 is squeezed to slide downward. When the rotating plate 8 completely passes through the sliding block 11, the sliding block 11 moves upward due to the action of the spring 13. The sliding block 11 cooperates with the cylinder 6 to ensure that the support rod 9 is always located under the upper cover plate 4, reducing the possibility of the support rod 9 rotating out from under the upper cover plate 4 due to collision during operation; when the cylinder 6 fails, the support rod 9 located under the upper cover plate 4 can effectively support the upper cover plate 4 to protect the workers' palms from being crushed.
