Description

Technical Field

[0001] This utility model relates to the field of cylindrical battery processing, specifically an adjustable negative pressure suction nozzle and probe integrated device. Background Technology

[0002] Cylindrical batteries are lithium-ion batteries with a cylindrical shape. Cylindrical batteries have formed a series of internationally unified standard specifications and models. The technology is mature and suitable for mass continuous production. The cylinder has a large specific surface area and good heat dissipation. Cylindrical batteries are generally sealed batteries, so there are no maintenance problems during use. The battery casing has high pressure resistance and will not swell like square or soft-pack batteries during use.

[0003] In traditional solutions, the probe (for current / voltage detection) and the negative pressure nozzle (for removing electrolytic gas) are usually separate structures, which can easily lead to spatial conflicts. The liquid injection port and the electrode tab are on the same side and the distance between them is too small (usually <3mm). The separate design makes it difficult to simultaneously contact the electrode tab and seal the liquid injection port, which can easily cause electrolyte leakage or gas residue. Furthermore, the inconveniently adjustable probe cannot adapt to cylindrical batteries of different diameters, affecting production efficiency. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, traditional solutions typically employ a separate structure for the probe and the negative pressure nozzle, which can easily lead to spatial conflicts. The liquid injection port and the electrode tab are on the same side and the distance between them is too small. The separate design makes it difficult to simultaneously contact the electrode tab and seal the liquid injection port, which can easily cause electrolyte leakage or gas residue. Furthermore, the inconveniently adjustable probe cannot adapt to cylindrical batteries of different diameters. This invention proposes an integrated device for an adjustable negative pressure nozzle and probe.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an adjustable negative pressure suction nozzle and probe integrated device, including a fixed base, a bearing fixedly connected to the inner cavity of the fixed base, a rotating rod fixedly connected to the inner wall of the inner ring of the bearing, an adsorption component provided in the inner cavity of the rotating rod, a slide rail fixedly connected to one side of the fixed base, the number of slide rails is multiple, a sliding seat is slidably connected to the surface of each slide rail, and a detection component is provided in the inner cavity of the sliding seat.

[0006] Preferably, a transmission disc is fixedly connected to the surface of the rotating rod, and a guide groove is provided on one side of the transmission disc. There are multiple guide grooves, and a guide rod is fixedly connected to one side of each sliding seat. The surfaces of the guide rods are slidably connected to the inner walls of the corresponding guide grooves.

[0007] Preferably, a cylinder is fixedly installed on the other side of the fixed base, and a toothed plate is fixedly connected to the output end of the cylinder. The toothed plate is L-shaped.

[0008] Preferably, a gear is fixedly connected to the surface of the rotating rod, and the teeth of the gear mesh with the teeth of the gear plate.

[0009] Preferably, the adsorption assembly includes a connector, one side of which is rotatably connected to one end of a rotating rod. A negative pressure suction rod is slidably connected to the inner cavity of the connector. One end of the negative pressure suction rod is fixedly connected to a suction nozzle body, and the other end of the negative pressure suction rod is fixedly connected to a rubber tube. Both the negative pressure suction rod and the rubber tube are located in the inner cavity of the rotating rod.

[0010] Preferably, a first spring is fixedly connected to one side of the nozzle body, and the other end of the first spring is fixedly connected to the other side of the connector.

[0011] Preferably, the detection assembly includes a probe body, the surface of which is slidably connected to the inner cavity of a sliding seat, a second spring is fixedly connected to one side of the sliding seat, and the other end of the second spring is fixedly connected to one side of the probe body.

[0012] The advantages of this utility model are:

[0013] In this invention, the fixed base plays a key connecting role. The adsorption component is located in the middle of the fixed base, and multiple detection components are arranged at equal intervals around the adsorption component. The detection components are connected to the slide rail on the fixed base via a sliding base. The rotating rod is sleeved around the adsorption component and can rotate along the fixed base via a bearing. The rotation of the rotating rod drives the transmission disk to rotate, and the rotation of the transmission disk drives the guide groove to move the guide rod. The guide rod then drives the sliding base to slide automatically along the slide rail, enabling the synchronous contraction or expansion of multiple detection components to adapt to batteries of different diameters for production assistance. This invention solves the problems of traditional solutions where the probe and negative pressure nozzle are usually separate structures, which can easily lead to spatial conflicts, the liquid injection port and the electrode tab being on the same side with too small a distance, and the separate design making it difficult to simultaneously contact the electrode tab and seal the liquid injection port, which can easily cause electrolyte leakage or gas residue. Furthermore, the inconveniently adjustable probe cannot adapt to cylindrical batteries of different diameters. Attached Figure Description
