Abstract
The utility model relates to a cylinder-shaped Lithium-ion battery process field, in particular to a cylinder-shaped Lithium-ion battery multi-series and parallel resistance welding special clamp. The cylinder-shaped Lithium-ion battery multi-series and parallel resistance welding special clamp comprises an upper clamp board and a lower clamp board which are connected with each other in a hinge mode, the external sides of the upper clamp board and the lower clamp board are provided with a reinforced rib plate, a fixing lock catch is arranged on the opening side of the upper clamp board and the lower clamp board. Due to the fact that the upper clamp board and the lower clamp board are disposed, the reinforced rib plate is arranged on the external sides of the upper clamp board and the lower clamp board, and the fixing lock catch is arranged on the opening side of the upper clamp board and the lower clamp board, therefore a plurality of cylinder-shaped Lithium-ion batteries are orderly fixed on the upper clamp board and the lower clamp board, and a nickel belt is arranged on the end surface of the cylinder-shaped Lithium-ion battery and starts to be welded. The cylinder-shaped Lithium-ion battery multi-series and parallel resistance welding special clamp has the advantages of being simple in positioning, fast, time saving, working efficiency improving, and a protruding portion is arranged on the corresponding position of the upper clamp board and the lower clamp board, a reserve nickel belt positioning groove is formed by the protruding portion, thereby more easily positioning the nickel belt and the end surface of the cylinder-shaped Lithium-ion battery, so that the welding time is shortened sharply.
Description
Technical field
The utility model relates to the cylindrical lithium ion battery manufacture field, relates in particular to a kind of cylindrical lithium ion battery multi-series and parallel resistance welded special fixture.
Background technology
Need to weld battery with resistance welder in the time of in the existing lithium ion battery production, the cell resistance welding is requisite link in the battery manufacturing process, and its effect is that the both positive and negative polarity of battery and nickel sheet are welded together, and has reached required application.
Because cylindrical lithium ion battery is difficult to fix, waste of time, inefficiency when producing, have just been caused when carrying out resistance welded.
The utility model content
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art, provides a kind of and saves time, the cylindrical lithium ion battery multi-series and parallel resistance welded special fixture of increasing work efficiency.
The utility model is to be achieved by the following technical programs:
A kind of cylindrical lithium ion battery multi-series and parallel resistance welded special fixture comprises two mutually hinged upper and lower clamping plate, and the described upper and lower clamping plate outside is provided with the reinforcement gusset, and the side that described upper and lower clamping plate are opened is provided with fixedly snap close.
The side correspondence position of described train wheel bridge and lower plate is provided with jut, and described jut forms the nickel strap locating slot of reserving.
The beneficial effects of the utility model are:
Owing to being provided with two mutually hinged upper and lower clamping plate, the described upper and lower clamping plate outside is provided with the reinforcement gusset, the side that described upper and lower clamping plate are opened is provided with fixedly snap close, with being fixed between the upper and lower clamping plate that branched cylindrical lithium ion battery is arranged, place the cylindrical lithium ion battery end face to weld nickel strap, this kind location is simple, and is quick, save the time, improved operating efficiency; And the side correspondence position of working as train wheel bridge and lower plate is provided with jut, and described jut forms the nickel strap locating slot of reserving, and is easier of nickel strap and cylindrical lithium ion battery end face location, and more shortened weld interval.
Description of drawings
Fig. 1 is main TV structure schematic diagram of the present utility model.
Among the figure: 1. strengthen gusset, 2. train wheel bridge, 3. lower plate, 4. hinge, 5. battery pack, 6. fixedly snap close, 7. jut.
The specific embodiment
In order to make those skilled in the art understand better the technical solution of the utility model, the utility model is described in further detail below in conjunction with accompanying drawing and most preferred embodiment.
As shown in Figure 1, the utility model comprises two by the mutually hinged upper and lower clamping plate of hinge 4, and the described upper and lower clamping plate outside is provided with strengthens gusset 1, and the side that described upper and lower clamping plate are opened is provided with fixedly snap close 6.The side correspondence position of described train wheel bridge 2 and lower plate 3 is provided with jut 7, and described jut forms the nickel strap locating slot of reserving.
With the train wheel bridge Unscrew, battery pack 5 is snapped in the lower plate during use, then that train wheel bridge is rotating closed, fixedly snap close locking is carried out battery pack resistance welded just passable at last.
Owing to being provided with two mutually hinged upper and lower clamping plate, the described upper and lower clamping plate outside is provided with the reinforcement gusset, the side that described upper and lower clamping plate are opened is provided with fixedly snap close, with being fixed between the upper and lower clamping plate that branched cylindrical lithium ion battery is arranged, place the cylindrical lithium ion battery end face to weld nickel strap, this kind location is simple, and is quick, save the time, improved operating efficiency; And the side correspondence position of working as train wheel bridge and lower plate is provided with jut, and described jut forms the nickel strap locating slot of reserving, and is easier of nickel strap and cylindrical lithium ion battery end face location, and more shortened weld interval.
The above only is preferred embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
