[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0031] The number of any elements in the accompanying drawings is for illustrative purposes only and not as a limitation, and any naming is for distinction only and has no limiting meaning.

[0032] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0033] This utility model provides a punching machine for button battery production, such as... Figures 1 to 3 As shown, it includes a frame 1, on which a corresponding feeding mechanism and a punching mechanism are provided. The punching machine mainly completes the punching process in the production of button batteries by cooperating with the feeding mechanism and the punching mechanism.

[0034] In this embodiment, the feeding mechanism includes a conveying roller 21 and an elastic support assembly 22. The conveying roller 21 includes two sets, namely an upper conveying roller 211 and a lower conveying roller 212. The elastic support assembly 22 includes a fixed support member 221 and an elastic support member 222. The lower conveying roller 212 is connected to the fixed support member 221, and the upper conveying roller 211 is movably engaged with the elastic support member 222 so that the upper conveying roller 211 can be elastically raised and lowered according to materials of different thicknesses.

[0035] In this embodiment, the upper conveyor roller 211 and the lower conveyor roller 212 jointly handle the material conveying, ensuring the stability of the material during the conveying process. In other embodiments, the upper conveyor roller 211 and the lower conveyor roller 212 can be configured to rotate passively, moving the metal strip by a traction device; or, the upper conveyor roller 211 and the lower conveyor roller 212 can be configured to rotate actively, moving the metal strip by a micro motor or similar device. It should be noted that using a micro motor or similar device to drive the rotation of the upper conveyor roller 211 and the lower conveyor roller 212 is prior art, and those skilled in the art should understand its structure, principle, and usage, which will not be described in detail here.

[0036] In this embodiment, the main function of the fixed support 221 is to support and fix the lower conveyor roller 212, ensuring its stability and accuracy during the operation of the punching machine. In this embodiment, the fixed support 221 includes a fixed frame 2211 and a first mounting rod 2212. One end of the first mounting rod 2212 is mounted on the fixed frame 2211, and the lower conveyor roller 212 is rotatably mounted on the other end of the first mounting rod 2212, allowing the lower conveyor roller 212 to rotate, which helps to smoothly convey materials in the feeding mechanism.

[0037] In this embodiment, the elastic support 222 includes a second mounting rod 2221, an elastic element 2222, and a support rod 2223. The elastic element 2222 is abutting and connected between the fixed frame 2211 and the support rod 2223. One end of the second mounting rod 2221 is rotatably mounted on the support rod 2223, and the upper conveyor roller 211 is rotatably mounted on the other end of the second mounting rod 2221. In this embodiment, the elastic element 2222 is abutting and connected between the fixed frame 2211 and the support rod 2223, providing necessary elastic support and cushioning for the upper conveyor roller 211. The support rod 2223 and the elastic element 2222 work together to provide stable support for the second mounting rod 2221, while allowing it to move with the rise and fall of the upper conveyor roller 211.

[0038] In this embodiment, the feeding mechanism also includes a support frame 23. The first mounting rod 2212 and the second mounting rod 2221 are rotatably mounted on the support frame 23 to ensure the stability and practicality of the feeding mechanism.

[0039] In this embodiment, the fixed support member 221 remains stationary, providing stable support for the lower conveyor roller 212, while the elastic support member 222 provides flexible support for the upper conveyor roller 211 through the buffering effect of the elastic element 2222, adapting to materials of different thicknesses. When the material passes through the feeding mechanism, the upper conveyor roller 211 will adjust its height according to the thickness of the material under the action of the elastic element 2222, ensuring the stability and accuracy of the material during the conveying process.

[0040] In this embodiment, the fixing frame 2211 includes a fixing part 201 and a connecting part 202. A support rod 2223 is located below the connecting part 202, and an elastic member 2222 is abutting and connected between the bottom end face of the connecting part 202 and the top end face of the support rod 2223. In this embodiment, the connecting part 202 extends along one side of the fixing part 201 to form a cantilever structure for mounting the elastic member 2222. The support rod 2223 forms a certain vertical distance from the connecting part 202, providing support for the second mounting rod 2221 in the elastic support member 222, and working together with the elastic member 2222 to provide necessary elastic support and buffering for the upper conveyor roller 211.

[0041] In this embodiment, the feeding mechanism includes two sets, which are symmetrically distributed on both sides of the central axis of the frame 1 in the horizontal direction, so that the metal strip is conveyed more smoothly and the metal strip is conveyed accurately.

[0042] In this embodiment, the stamping mechanism includes a power component 31 and a stamping head 32. The power component 31 is driven by the stamping head 32 to drive the stamping head 32 to move up and down. In this embodiment, the power component 31 includes a drive element (not shown in the figure), a transmission disk 311, a connecting rod 312, and a slider 313. The drive element is linked to the transmission disk 311. The two ends of the connecting rod 312 are rotatably connected to the transmission disk 311 and the slider 313, respectively. A slide rail 11 is provided on the frame 1, and the slider 313 is slidably engaged with the slide rail 11. The stamping head 32 is located on the slider 313. In this embodiment, the drive element is a servo motor.

[0043] In this embodiment, the stamping mechanism is the core component of the stamping machine, responsible for stamping materials into the required shape or size. When the drive unit is activated, it drives the transmission disk 311 to rotate via a linkage connection. The rotation of the transmission disk 311 causes the connecting rod 312 to swing, which in turn pushes the slider 313 to move up and down along the slide rail 11. The stamping head 32 on the slider 313 moves up and down accordingly, stamping the material. In this embodiment, the stamping mechanism, through the drive and transmission of the power component 31, realizes the lifting and lowering movement of the stamping head 32 and the stamping processing of the material. This not only effectively improves the production efficiency of the stamping machine but also ensures the stability and accuracy of the stamping process. At the same time, the frame 1 and the slide rail 11 provide necessary support and guarantee for the stable operation of the stamping mechanism.

[0044] In other embodiments, precise lifting and stamping actions of the punch head 32 can be achieved by precisely controlling the output of the drive unit and the rotation angle of the transmission disk 311.

[0045] In this embodiment, a support base 12 is provided on the frame 1 below the punching head 32. The support base 12 is provided with a die hole 121 corresponding to the punching head 32. The horizontal height of the top end face of the support base 12 is consistent with the horizontal height of the top end face of the lower conveyor roller 212, which ensures that the material can be smoothly transferred to the support base 12 during conveying. This can effectively improve the continuity and stability of material conveying, avoid jumping or jamming problems caused by height difference, and thus effectively improve the production efficiency and quality of the punching machine.

[0046] In this embodiment, the main function of the support base 12 is to provide a stable platform for supporting and positioning the material to be stamped. The die hole 121 on the support base 12 corresponds to the stamping head 32. When the stamping head 32 descends, it passes through the die hole 121 to stamp the material. When the material is being conveyed, it is smoothly conveyed onto the support base 12. At this time, the stamping head 32 begins to descend under the drive of the power component 31, passes through the die hole 121 on the support base 12 to stamp the material. After stamping is completed, the stamping head 32 rises back to its original position, and the material continues to be conveyed to the next process for further processing.

[0047] In this embodiment, a receiving hole (not shown in the figure) corresponding to the die hole 121 is provided on the frame 1 below the support base 12. A feeding channel 13 is provided on the frame 1, and the axis of the feeding channel 13 is perpendicular to the axis of the receiving hole. After the punching head 32 completes the punching action, the material falls from the die hole 121 and enters the feeding channel 13 through the receiving hole. At this time, the conveyor belt 131 starts to run under the drive of the drive device, picks up the material from the receiving hole, and transports it to the next process along the feeding channel 13.

[0048] In this embodiment, a conveyor belt 131 runs through the feeding channel 13. The conveyor belt 131 is made of a flexible material, which allows it to adapt to changes in the shape and size of the material, ensuring the stability and continuity of the material during the conveying process.

[0049] It should be noted that the conveyor belt 131 starting to operate under the drive of the drive device to transport materials is existing technology. Those skilled in the art should be clear about its structure, principle and usage, etc., and will not be described in detail here.

[0050] The working principle of the punching machine for button battery production provided by this utility model is as follows: The metal strip to be processed is placed between two sets of feeding mechanisms. The upper conveyor roller 211 presses the metal strip under the action of the elastic support member 222. The driving member drives the transmission disk 311 to rotate, and through the connecting rod 312, the slider 313 slides up and down along the slide rail 11, thereby driving the punching head 32 to move up and down to punch the metal strip. The punched electrode sheet falls into the receiving hole through the die hole 121 and is finally transported to the next process through the feeding channel 13.

[0051] Based on the above description in this specification, those skilled in the art will also understand that the following terms used, such as "upper," "lower," "front," "rear," "left," "right," "width," "horizontal," "top," "bottom," "inner," and "outer," are terms indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings of this specification. They are only for the purpose of facilitating the explanation of the present invention and simplifying the description, and do not explicitly or implicitly suggest that the device or element involved must have the specific orientation, or be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms should not be understood or interpreted as limitations on the present invention.

[0052] In addition, in the description of this specification, "multiple" means at least two, such as two, three or more, etc., unless otherwise expressly and specifically defined.
