Description

Technical Field

[0001] The utility model relates to the field of lithium battery manufacturing equipment, in particular to an automatic core rod feeding mechanism for a lithium battery winding machine. Background Art

[0002] At present, the central holes of lithium battery cells on the market are relatively small, prone to deformation, and usually cannot meet the process requirements of the cells. Keeping the central hole of the cell unchanged is important for the cell. For example, the central hole of a cylindrical battery helps with exhaust, allowing the gas generated inside the battery to be discharged smoothly, thereby reducing the pressure inside the battery and preventing the battery from exploding violently. At the same time, this hole also promotes heat dissipation, better dissipating the heat generated when the battery is working. Another example is that by inserting a steel needle into the central hole of a cylindrical battery, the performance of the battery can be improved because the instability of the internal structure of the battery may lead to poor electrode contact, affecting the electrical conductivity and energy transfer efficiency of the battery. Therefore, the applicant wants to develop a lithium battery winding machine. The main idea of this machine is to insert a core rod into the central hole of the cell to make it not easily deformed. Among them, in order to improve the overall automation degree of the equipment, it is also necessary to develop an automatic core rod feeding mechanism for how to achieve automatic feeding of multiple core rods one by one. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is how to achieve automatic feeding of core rods one by one. The specific technical solution is as follows:

[0004] An automatic core rod feeding mechanism for a lithium battery winding machine includes a base, a transverse movement component, a lifting component, a jacking block, a core rod storage box, and a fixing block. The transverse movement component is installed above the base, the output end of the transverse movement component is installed with the lifting component, the output end of the lifting component is installed with the jacking block. The transverse movement component and the lifting component cooperate with each other to drive the jacking block to move left and right and up and down. The core rod storage box contains multiple core rods. The bottom surface of the core rod storage box is an inclined surface. One end of the core rod storage box is provided with an opening, and the opening is connected to the jacking block. The core rods in the core rod storage box roll to the jacking block. There are two fixing blocks spaced apart from each other, and the jacking block is located between the two fixing blocks. The fixing blocks are fixedly installed on the frame of the lithium battery winding machine.

[0005] As a preferred solution of the utility model, the surface of the jacking block is provided with a plurality of jacking steps arranged in increasing order. The core rods are carried and moved by the jacking steps. The surface of the fixing block is provided with fixing steps arranged in increasing order.

[0007] As a preferred embodiment of the present utility model, the transverse movement assembly includes a transverse movement cylinder, a transverse movement plate, a slider, and a slide rail.

[0016] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0017] As Figures 1 to 4 shown, an automatic core rod feeding mechanism of a lithium battery winding machine includes a base 1, a transverse movement assembly, a lifting assembly, a jacking block 4, a core rod storage box 5, and a fixing block 6. The transverse movement assembly is installed above the base 1, the output end of the transverse movement assembly is installed with the lifting assembly, the output end of the lifting assembly is installed with the jacking block 4. The transverse movement assembly and the lifting assembly cooperate with each other to drive the jacking block 4 to move left and right and up and down. The core rod storage box 4 contains multiple core rods. The bottom surface of the core rod storage box 5 is an inclined surface. One end of the core rod storage box 5 is provided with an opening, and only one core rod 7 can pass through the opening each time. Therefore, it can ensure that the feeding is separated one by one. The opening is docked with the jacking block 4, and the core rods in the core rod storage box 5 roll to the jacking block 4. There are two fixing blocks 6 and they are spaced apart. The jacking block 4 is located between the two fixing blocks 6. The fixing blocks 6 are fixedly installed on the frame of the lithium battery winding machine.

[0018] Specifically, the surface of the jacking block 4 is provided with a plurality of jacking steps 41, and the jacking steps 41 are arranged in ascending order. The core rod 7 is carried by the jacking steps 41 to move. The surface of the fixing block 6 is provided with fixing steps 61, and the fixing steps 61 are arranged in ascending order. The fixing steps 61 are used to temporarily carry the core rod. When the jacking steps 41 are in the low position, they are lower than the fixing steps 61. When the jacking steps 41 are in the high position, they are higher than the fixing steps 61. In this embodiment, it is described with 3 jacking steps 41 and 3 fixing steps 61 respectively, and the specific quantity can be increased or decreased. The lifting assembly drives the jacking block 4 upward, and the leftmost jacking step 41 rises so that the core rod is not at the same horizontal position as the opening. Then the transverse movement assembly drives the jacking block 4 to move right, and the jacking block 4 drives the core rod 7 to move right. The jacking block 4 and the fixing block 6 are staggered by one core rod position. The lifting assembly drives the jacking block 4 to move downward, and both ends of the core rod are carried on the leftmost fixing step 61 so that the core rod will not drop with the jacking block 4. The transverse movement assembly drives the jacking block 4 to move left to reset. Then repeat that the lifting assembly drives the jacking block 4 upward, and the second jacking step 41 rises so that the core rod originally on the leftmost fixing step 61 is carried on the second jacking step 41. Then the transverse movement assembly drives the jacking block 4 to move right, and then the lifting assembly drives the jacking block 4 to move downward. Both ends of the core rod are carried on the second fixing step 61 so that the core rod will not drop with the jacking block 4. The transverse movement assembly drives the jacking block 4 to move left to reset, and so on to gradually send out the core rod.

[0019] Specifically, the bottom surfaces of the jacking step 41 and the fixing step 61 are inclined planes, making the left side higher than the right side, which can prevent the mandrel 7 from falling out.

[0020] Specifically, the transverse movement assembly includes a transverse movement cylinder 21, a transverse movement plate 22, a slider 23, and a slide rail 24. The transverse movement cylinder 21 is fixedly installed on the base 1. The piston rod of the transverse movement cylinder 21 extends horizontally and is connected to the transverse movement plate 22. The slider 23 is installed at the bottom of the transverse movement plate 22. The slider 23 is slidably connected to the slide rail 24. The slide rail 24 is fixedly installed on the base 1. The transverse movement cylinder 21 drives the transverse movement plate 22 to move left and right under the guiding action of the slider 23 and the slide rail 24.

[0021] Specifically, the lifting assembly includes a lifting cylinder 31, a guiding rod 32, and a guiding sleeve 33. The piston rod of the lifting cylinder 31 extends upward and is connected to the jacking step 4. The guiding rods 32 are installed on the front and rear sides of the bottom of the jacking step 4. The guiding rods 32 are slidably connected to the guiding sleeve 33. The guiding sleeve 33 is fixedly installed on the transverse movement plate 22. The lifting cylinder 31 drives the jacking step 4 to move up and down.

[0022] As Figure 4 shown, the working principle of this solution is described in the following process: ① Initial waiting position: The mandrel in the mandrel storage box 5 rolls to the jacking block 4; ② Mandrel jacking: The lifting assembly drives the jacking block to move above, and the leftmost jacking step 41 rises so that the mandrel is not at the same horizontal position as the opening; ③ Mandrel right movement: The transverse movement assembly drives the jacking block 4 to move right, and the jacking block 4 drives the mandrel 7 to move right; ④ Mandrel descending in place: The lifting assembly drives the jacking block 4 to move down, and the two ends of the mandrel are supported on the fixing step 61 so that the mandrel will not descend with the jacking block 4, and the mandrel descends in place; ⑤ Reset: The transverse movement assembly drives the jacking block 4 to move left and reset, and continuously repeats the above steps to stably and quickly send out the mandrel.

It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several simple deductions or substitutions can still be made, which should all be regarded as belonging to the protection scope of the present invention.
