Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a perforated plate limiting mechanism. Background Technology

[0002] The battery cap is an important component of a battery; it provides a sealed function and acts as a safety valve, such as... Figure 1 As shown, the battery cap 100 includes a perforated plate 101 and a rigid terminal 102. On the assembly machine, the perforated plate 101 needs to be placed above the rigid terminal 102 and located at the center of the top surface of the rigid terminal 102. Since the perforated plate 101 will shift relative to the rigid terminal 102 during the rotation of the turntable 1' on the assembly machine, a device to prevent the perforated plate 101 from shifting needs to be designed.

[0017] like Figures 2-5 As shown, this utility model is a perforated plate limiting mechanism, including a turntable 1, a drive plate 2, an eccentric block 3, and a telescopic mechanism 4.

[0018] The drive disk 2 is fixedly installed in the middle on the top surface of the turntable 1. A suspended section is formed between the outer side of the drive disk 2 and the turntable 1. The eccentric block 3 is fixedly installed on the outer edge of the drive disk 3. The outer side of the eccentric block 3 has an outwardly extending protruding edge 31. The telescopic mechanism 4 is installed on the outer side of the turntable 1 and located below the drive disk 2.

[0019] The telescopic mechanism 4 includes a limiting base 41, a linear slide rail pair 42, a slider 43, a translation plate 44, a longitudinal plate 45, a translation cam 46, a lifting cam 47, a lifting support column 48, a lifting spring 49, a translation spring 410, and a limiting plate 411.

[0020] The limiting base 41 is fixedly installed on the outside of the turntable 1. The linear slide rail pair 42 is installed on the top surface of the limiting base 41. The slider 43 slides on the linear slide rail pair 42. The bottom surface of the translation plate 44 is installed on the top surface of the slider 43 and can move in both horizontal and vertical directions. The two ends of the translation spring 410 are respectively connected to the limiting base 41 and the slider 43. The bottom surface of the longitudinal plate 45 abuts against the top surface of the translation plate 44. A lifting spring 49 is provided between the bottom surface of the longitudinal plate 45 and the top surface of the translation plate 44. The lower end of the translation cam 46 is fixed to the translation plate 44. The upper part of the translation cam 46 abuts against the outer wall of the eccentric block 3 so that the eccentric block 3 drives the translation plate 44 to move horizontally through the translation cam 46. The bottom surface of the lifting column 48 is fixed to the top surface of the longitudinal plate 45. The inner end of the lifting cam 47 is fixed to the lifting column 48 in the horizontal direction and the outer side of the lifting cam 47 abuts against the bottom surface of the protrusion 31 of the eccentric block 3 so that the eccentric block 3 drives the longitudinal plate 45 to move up and down through the lifting cam 47. The inner end of the limiting plate 411 is fixed to the outer side of the longitudinal plate 45 and the outer end of the limiting plate 411 extends toward the assembly station.

[0021] The bottom surface of the translation plate 44 is provided with a locking block 441, which can abut against the locking block 431 on the top surface of the slider 43, so that the translation plate 44 can drive the slider 43 to move outward together through the locking block.

[0022] The outer side of the limiting plate 411 is provided with a round hole 412 that can hold the perforated plate 101.

[0023] The working principle of this utility model:

[0024] During operation, the turntable 1 rotates, driving the telescopic mechanism 4 mounted on it to rotate to various processing stations. During the rotation of the turntable 1, the translation cam 46 in the telescopic mechanism 4 can abut against the eccentric block 3, so that the eccentric block 3 can drive the translation plate 44 to move horizontally through the translation cam 46. The lifting cam 47 can abut against the eccentric block 3, so that the eccentric block 3 can drive the longitudinal plate 45 to move up and down through the lifting cam 47. The outer end of the limiting plate 411 mounted on the longitudinal plate 45 can extend to the assembly station. A round hole 412 is provided on the outer side of the limiting plate 411 to lock the perforated plate 101. During the rotation of the turntable 1, the round hole 412 on the limiting plate 411 is gapped into the outer circle 412 of the perforated plate 101 to prevent the perforated plate 101 from moving.
