Description

Technical Field

[0001] The utility model relates to the field of lithium battery processing equipment, in particular to a cylindrical lithium battery clamping device. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and non-aqueous electrolyte solutions. With the gradual improvement of equipment for spraying insulating paint on cylindrical lithium batteries one by one, equipment for spraying insulating paint on multiple cylindrical lithium batteries at the same time has also been gradually developed to improve production efficiency. However, in the clamping process of existing cylindrical lithium batteries, two relatively movable bases are generally used, or a fixed seat is set on one side of the base and a relatively movable sliding seat is set on the other side to achieve clamping of the cylindrical lithium battery. Therefore, the structure is relatively large. When the clamping mechanism is coordinated with other mechanisms, a larger bearing mechanism is required to achieve multi-dimensional movement, or only a single moving direction can be set, such as vertical or horizontal. Utility Model Content

[0003] The main purpose of the utility model is to propose a cylindrical lithium battery clamping device, which aims to improve the clamping device of the cylindrical lithium battery, reduce its volume, and make it suspended, so as to facilitate installation on different mobile mechanisms and reduce interference between various mechanisms.

[0004] To achieve the above-mentioned purpose, the utility model proposes a cylindrical lithium battery clamping device comprising a frame, a fixing seat fixedly arranged on the frame, and an adjusting frame sliding relative to the fixing seat, wherein the adjusting frame is suspended, and the fixing seat is provided with a first driving device for driving the adjusting frame to slide;

[0005] The fixing seat and the adjusting frame are respectively provided with a driving roller and a driven roller. The driving roller is connected to a driving rotating motor and can drive the driving roller to rotate.

[0006] The sliding adjustment frame makes the clamping mechanism of the cylindrical lithium battery simpler and smaller in size, reduces interference during displacement, and allows the entire fixture to be installed in a predetermined device, thereby reducing the production cost of the equipment. At the same time, the production efficiency is effectively improved, that is, the clamping step shortens the time it takes to clamp the cylindrical lithium battery from the fixture.

[0021] like Figures 1 to 3 As shown, a cylindrical lithium battery clamping device,

[0022] It includes a frame 1, a fixed seat 41 fixed to the frame 1, and an adjustment frame 42 sliding relative to the fixed seat 41, the adjustment frame 42 is suspended, and the fixed seat 41 is provided with a first driving device that drives the adjustment frame 42 to slide;

[0023] The fixing seat 41 and the adjusting frame 42 are respectively provided with a driving roller 43 and a driven roller 44 . The driving roller 43 is connected to a driving rotating motor 45 and can drive the driving roller 43 to rotate.

[0024] The sliding adjustment frame 42 makes the clamping mechanism of the cylindrical lithium battery simpler and smaller in size, reduces interference during displacement, and allows the entire fixture to be installed in a predetermined device, thereby reducing the production cost of the device. At the same time, the production efficiency is effectively improved, that is, the clamping step shortens the time it takes to clamp the cylindrical lithium battery from the fixture.

[0025] Specifically, the fixing seat 41 and the adjusting frame 42 are respectively provided with a plurality of active rollers 43 and driven rollers 44 arranged at intervals, and each active roller 43 is individually connected to an individual active rotating motor 45. Of course, the active rotating motor 45 can also drive a plurality of active rollers 43 at the same time through structures such as belts and gears, but the rotation position adjustment of a single cylindrical lithium battery cannot be achieved.

[0026] In the embodiment of the utility model, the fixing seat 41 is provided with a guide sleeve 51, and the adjusting frame 42 is provided with an adjusting slide bar 52 sliding toward the guide sleeve 51, and the adjusting slide bar 52 is slidably mounted on the guide sleeve 51. Thus, the relative spacing between the active roller 43 and the driven roller 44 is adjusted, thereby achieving the clamping and fixing of the two ends of the cylindrical lithium battery.

[0027] Specifically, the end surface of the active roller 43 is provided with a fixed electromagnet 6. The electromagnet 6 can be provided to ensure that the cylindrical lithium battery is attached to one end of the active roller 43 even when it is not rotating, thereby reducing scratches caused by the movement of the adjustment frame 42 and ensuring stable clamping.

[0028] In the embodiment of the utility model, the first driving device is a telescopic motor 53, and the telescopic motor 53 is fixedly disposed on the fixing seat 41. The driving end of the telescopic motor 53 is connected to the adjustment seat, thereby realizing the relative position adjustment of the fixing seat 41 and the adjustment seat.

[0029] Specifically, the end surface of the driven roller 44 is provided with an anti-slip pad 2 to improve the clamping stability.

[0030] In the embodiment of the utility model, the middle part of the anti-skid pad 2 is provided with an avoidance hole 3, and the anti-skid pad 2 is provided with a mesh structure at a position away from the avoidance hole, thereby improving the friction force and thus improving the clamping stability of the cylindrical lithium battery.

[0031] Specifically, two adjusting slide bars 52 are provided and are spaced apart from each other.

[0032] The frame is mounted on a horizontal sliding device 7, which is used to drive the fixed seat to move to switch between the processing position and the transportation position; the horizontal sliding device includes a horizontal guide rail 71, a horizontal slider 72 slidably mounted on the horizontal guide rail, and a horizontal screw pair 73 for driving the horizontal slider to move.

[0033] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
