[0011] As a preferred embodiment, a plurality of the mounting blocks are slidably mounted on the inner walls of the corresponding limiting sliding grooves.

[0012] As a preferred embodiment, support legs are fixed at the four corners of the bottom end of the operating table.

[0013] Compared with the prior art, the automatic punching machine for lithium battery production provided by the utility model has at least the following beneficial effects:

DETAILED DESCRIPTION

[0021] The present invention will be further described below in conjunction with the embodiments.

[0022] See also Figure 1-4The utility model provides an automatic punching machine for lithium battery production, including an operating table 1 and a top plate 3. Brackets 2 are fixed to the four corners of the top of the operating table 1. The top plate 3 is fixedly connected to the operating table 1 through the brackets 2. A servo cylinder 4 is fixed at the center of the top of the top plate 3. A mounting plate 5 is fixed to the driving end of the servo cylinder 4. A punching mechanism 6 is fixed to the center of the bottom end of the mounting plate 5. A driving motor 8 is fixed to the center of the operating table 1. A positioning mechanism 10 is fixed to the driving end of the driving motor 8.

[0023] By placing the lithium battery casing on the surface of the operating table 1, when the lithium battery casing contacts the induction sensor 7, the servo cylinder 4 can be started, thereby driving the servo cylinder 4 to be subjected to force, and further driving the mounting plate 5 to move. The mounting plate 5 can be subjected to force, so that it can drive the punching mechanism 6 to move, thereby punching holes in the lithium battery casing.

[0024] Further Figure 1 , Figure 2 , Figure 3 As shown, it is worth explaining in detail that the positioning mechanism 10 includes a rotating member 101, the bottom end of the rotating member 101 is fixed to the driving end of the driving motor 8, both ends of the rotating member 101 are rotatably mounted with a rotating rod 102, the other end of the rotating rod 102 is rotatably mounted with a sliding plate 103, and both sides of the top of the sliding plate 103 are fixed with mounting blocks 104.

[0025] When the sensing sensor 7 is subjected to pressure, it can drive the driving motor 8 to start, thereby driving the rotating member 101 to rotate, and further driving the rotating rod 102 to be subjected to force, so that it can drive the sliding plate 103 to slide within a limited position through the rotation force, thereby driving the clamping plate 11 to be subjected to force, thereby clamping and positioning the lithium battery casing, so that the lithium battery casing can remain stable when punching.

[0026] Further Figure 2 , Figure 3 As shown, it is worth explaining in detail that the top ends of the two mounting blocks 104 are respectively fixed with clamping plates 11 .

[0027] The clamping plate 11 can mainly bear force through the mounting block 104, thereby positioning the lithium battery housing.

[0028] This solution has the following working process: when it is necessary to punch a hole in the lithium battery casing, the lithium battery casing is placed on the surface of the induction sensor 7, so that the servo cylinder 4 and the drive motor 8 can be started at the same time, thereby driving the servo cylinder 4 to be subjected to force, and further driving the mounting plate 5 to move, and then the mounting plate 5 can be subjected to force, so that it can drive the punching mechanism 6 to move, thereby punching a hole in the lithium battery casing, and then through the drive motor 8, it can drive the positioning mechanism 10 to be subjected to force, thereby realizing the positioning of the lithium battery casing during punching, thereby realizing stable punching of the lithium battery casing.

[0029] According to the above working process, it can be known that: when punching a hole in the lithium battery shell, by placing the lithium battery shell on the surface of the induction sensor 7, it is possible to start the servo cylinder 4 and the drive motor 8 at the same time, thereby keeping the lithium battery shell stable during positioning.

[0031] When the induction sensor 7 contacts the lithium battery housing, the servo cylinder 4 and the drive motor 8 can be started simultaneously, thereby improving the practicality of the lithium battery drilling effect.

[0032] Further Figure 1 , Figure 2 and Figure 4 As shown, it is worth explaining in detail that the four corners of the surface of the operating table 1 are all provided with rectangular limiting sliding grooves 12, and the limiting sliding grooves 12 are connected to the rotating grooves 9.

[0033] The limiting slide groove 12 can mainly facilitate the mounting block 104 to bear force, thereby facilitating the sliding plate 103 to perform limiting sliding, thereby driving the clamping plate 11 to perform limiting sliding, thereby clamping and positioning the lithium battery housing.

[0034] Further Figure 1 , Figure 2 and Figure 4 As shown, it is worth to explain in detail that a plurality of mounting blocks 104 are mounted on the inner wall of the corresponding limiting sliding groove 12 in a limited sliding manner.

[0035] Further Figure 1 , Figure 4 As shown, it is worth explaining in detail that support legs 13 are fixed to the four corners of the bottom end of the operating table 1.

[0036] In summary: by placing the lithium battery casing on the surface of the operating table 1, when the lithium battery casing contacts the induction sensor 7, the servo cylinder 4 can be started, thereby driving the servo cylinder 4 to be subjected to force, and further driving the mounting plate 5 to move, and then the mounting plate 5 can be subjected to force, so that it can drive the punching mechanism 6 to move, thereby the lithium battery casing can be punched and positioned, and then when the driving motor 8 is started, it can drive the rotating member 101 to rotate, and further drive the rotating rod 102 to be subjected to force, so that it can drive the sliding plate 103 to slide within a limited position through the rotation force, thereby driving the clamping plate 11 to be subjected to force, thereby clamping and positioning the lithium battery casing, so that the lithium battery casing can remain stable during punching.
