Abstract
The utility model discloses a test tool for the laser welding tensile force of a round lithium ion battery. The test tool comprises a handle and a limit unit, wherein the handle is used for clamping a tensile force test device; and the limit unit is fixed with the handle and is used for loading a battery cover and a cathode tab which are fixed together from one side and limiting the movement space of the battery cover and the cathode tab in a certain range. After the battery cover and the cathode tab are loaded in the limit unit and then limited, the welding tensile force on the battery cover and the cathode tab is tested in a way that an external tensile force is applied to the handle, so the requirement of production sampling inspection is met, and the laser welding tensile force of the round lithium ion battery can be reliably detected. At the same time, the test tool has the characteristics of simple structure, safety, reliability and convenience in operation.
Description
Technical field
The utility model relates to a kind of round lithium ion battery Laser Welding (LBW) tensile test frock, and whether the welding that is used to detect between round lithium ion cell positive ear and battery cover is effective.
Background technology
Round lithium ion battery is a kind of high-octane environmental protection battery that stored, and inside battery anode ear and battery cover fetch through Laser Welding (LBW) and link together, so the quality of laser bonding directly has influence on the usability and the security performance of battery.So it is the key link of judging the laser bonding effect that round battery laser welding pulling force detects.
At present, the method for detection laser weldering pulling force is with the battery after the laser bonding, cuts off then from the anode ear root with blade earlier, clamps anode ear with the tautness meter clip again and carries out tensile test.The method of this use blade cuts lug not only has danger, and inevitably welding is caused damage in the operating process; In addition, because anode ear is thinner, certain difficulty is arranged when clamping with the tautness meter clip; Thereby this method of testing is both dangerous time-consuming, and test result is not accurate enough again, so press for improvement.
The utility model content
The purpose of the utility model is to provide a kind of round lithium ion battery Laser Welding (LBW) tensile test frock, and its test result is accurate, simultaneously easy to operate, safety.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is following:
A kind of round lithium ion battery Laser Welding (LBW) tensile test frock comprises that one is used for the handle of device for testing tensile force clamping and the battery cover that will weld together with fixing being used for of described handle and anode ear and packs into and the activity space of battery cover and anode ear is limited qualification unit within the specific limits from a side.
The round lithium ion battery Laser Welding (LBW) of the utility model pulling force detects frock; Battery cover and anode ear are packed into limit the unit and limit after; The going up of handle that acts on connection through external broach tested the weldering power of drawing of battery cover and anode ear, not only can reach and produce the sampling observation test requirements, and can carry out round lithium ion battery laser bonding pulling force reliably and detect; Simultaneously, the utlity model has simple in structure, safe and reliable, convenience operation.
Description of drawings
The front view of the round lithium ion battery Laser Welding (LBW) tensile test frock that Fig. 1 the utility model embodiment provides;
Fig. 2 is the perspective view of the round lithium ion battery Laser Welding (LBW) tensile test frock that provides of the utility model embodiment;
Fig. 3 is the use synoptic diagram that the utility model is executed the round lithium ion battery Laser Welding (LBW) tensile test frock that example provides.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing.
Referring to Fig. 1-2; A kind of round lithium ion battery Laser Welding (LBW) tensile test frock comprises that one is used for the handle 21 of device for testing tensile force clamping and the battery cover that will weld together with fixing being used for of described handle and anode ear and packs into and the activity space of battery cover and anode ear is limited qualification unit 22 within the specific limits from a side.
Described qualification unit 22 is formed by connecting upper limit plate 23, left and right sides limiting plate 24,25 and two lower limiting boards, 26,27 head and the tail on same surface level; Wherein two lower limiting boards 26, offer between 27 battery cover and anode ear are used for the opening 28 that anode ear passes through when a side packed into, described limiting plate surrounds
Described handle 21 is located at the top middle portion of said qualification unit 22.
More excellent, described handle 21 is an integral structure with said qualification unit 22.
The principle of work and the operating process of the utility model are following:
Referring to Fig. 3; The described Laser Welding (LBW) tensile test of the utility model frock 2 usefulness tautness meter clips 1 are clamped, the battery cover after the laser bonding 3 are inserted in Laser Welding (LBW) tensile test frock 2 from a side of Laser Welding (LBW) tensile test frock 2, adjust tautness meter after; Use the main part 5 that pulls battery to drop-down; At this moment, the value of thrust data when tautness meter promptly records anode ear 4 and is pulled away from battery cover 3, these value of thrust data promptly are the values of thrust of round lithium ion battery laser bonding.Therefore, this Laser Welding (LBW) tensile test frock can detect battery laser weldering pulling force effectively.
The advantage of the utility model is:
(1) avoided manual operation to the influence that welding effect causes, made test result more accurately and reliably;
(2) avoid using the blade cuts anode ear, guaranteed operator's safety, also saved blade simultaneously;
(3) simplified operating process, made more convenient operation, more saved time.
The round lithium ion battery Laser Welding (LBW) of the utility model tensile test frock, owing to adopted the mentality of designing of innovation, safe in utilization, convenient, fast, and cost is lower, and applicable surface is wider, and test result is more accurately and reliably.
The above only is the preferred implementation of the 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 improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
