The cylindrical battery comprises a shell and cover plates, and the laser welding jig for the cylindrical battery is used for clamping the shell of the cylindrical battery and welding the cover plates and the shell. The laser welding jig for the cylindrical battery comprises a bottom plate, a rotary jig plate, a motor, a belt, a first positioning part and a second positioning part, the rotary jig plate is disposed on the bottom plate, the first positioning part and the second positioning part are arranged on two opposite sides of the rotary jig plate and axially position the cylindrical battery along the axial direction of the rotary jig plate, the belt is movably connected with the motor and the rotary jig plate, and the rotary jig plate is driven by the motor to rotate. Mechanical positioning is adopted when the laser welding jig for the cylindrical battery is used for welding the cover plates at two ends of the cylindrical battery, and accordingly welding reliability, welding qualified rate and automation degree are improved.
Description
Technical field
The utility model relates to a kind of fixture for laser welding, relates in particular to a kind of fixture for laser welding that is used for cylindrical battery.
Background technology
Characteristics such as cylindrical battery has that operating voltage height, operating temperature range are wide, long service life, memory-less effect, pollution-free, specific energy height.From nineteen ninety Sony release commercial cylindrical battery one, cylindrical battery has passed through developing stage fast, electrokinetic cell field particularly, cylindrical battery has become the maximum market of motive-power battery.In addition, along with climate warmingization and resource that the whole world is more and more serious are nervous, develop the new energy and necessitate.Present commercial cylindrical battery monomer mainly contains four kinds of structures, is respectively square bar housing battery, square electric battery with plastic case, cylindrical battery and Soft Roll polymer battery.Wherein, cylindrical battery is ripe with its production equipment, and advantages such as high conformity, discharge-rate height become the battery types that range of application is the widest in four kinds of batteries, the user accepts most.Along with the development of industry and the demand in market, cylindrical battery market will further be developed to the large-sized power system orientation.The sealing to cylindrical battery mainly is roll extrusion sealing and laser welded seal in the industry at present; And adopt the mode of laser weld for the sealing of cylindrical battery, cover plate and the housing of the big volume of high power capacity more; Principle is to pass through the cavity cover to the astigmatism that irradiation light irradiates to refractor, shines focusing lens through refractor, shines the battery container surface then; Housing is heated up, through heat exchange pattern welding is realized in the inside that heat is sent to material again.The advantage of laser weld has; Good seal performance; Manufacture craft is simple, cost of manufacture is low etc., and laser weld generally is that the rolling clamp dish is installed on the workbench of laser-beam welding machine, and the rolling clamp dish is connected with friction pulley; Friction pulley is connected with motor, and electric motor starting is accomplished battery rotation continuous welding through friction pulley driven rotary clamping apparatus disk during welding.Though above welding method can realize continuous welding to the sealing of cylindrical battery, still there is certain defective in this kind welding manner.Because the special type cylindrical battery of structure can not can fasten as rectangular cell cover plate and housing fully, before welding, need with the pulse welding machine cover plate and housing location.On the battery rolling clamp time if any splitting behind the anchor point bump that collides with, crack or trachoma can appear in the part of splitting during laser weld, laser radiation is to inside battery, damage the inside battery structure serious possibly cause battery short circuit.
The utility model content
In order to overcome the deficiency of above-mentioned prior art; The utility model provides a kind of fixture for laser welding that is used for cylindrical battery; Cylindrical battery comprises housing and cover plate; Be used for housing that the fixture for laser welding of cylindrical battery is used for the clamping cylindrical battery so that cover plate and housing are welded; Said cylindrical battery comprises columniform housing and is fastened on the cover plate of said housing, and the said fixture for laser welding that is used for cylindrical battery comprises base plate, be arranged at rolling clamp dish, motor, the belt of base plate and be arranged at first keeper and second keeper of the relative both sides of rolling clamp dish, and said first keeper and second keeper are along the said cylindrical battery of axial location of said rolling clamp dish; Said belt is movably connected on said motor and rolling clamp dish, and said rolling clamp dish rotates under said driven by motor.
Further being improved to of the utility model, said first keeper and second keeper are cylinder, said first keeper and second keeper move to support the cover plate of said cylindrical battery towards said rolling clamp dish.
Compared to prior art, the fixture for laser welding that is used for cylindrical battery of the utility model adopts mechanical positioning, increases welding reliability, improves solder yield, improves automaticity when the cover plate to the cylindrical battery two ends welds.
Description of drawings
Fig. 1 is the structural representation that the utility model is used for the fixture for laser welding of cylindrical battery.
The specific embodiment
Below in conjunction with the description of drawings and the specific embodiment the utility model is further specified.
See also Fig. 1; The utility model provides a kind of fixture for laser welding 10 that is used for cylindrical battery; Be used for clamping cylindrical battery (figure does not show) and to cooperate plumb joint (figure does not show) cylindrical battery welded, said cylindrical battery comprises columniform housing and is fastened on the cover plate of said housing.The said fixture for laser welding 10 that is used for cylindrical battery comprises base plate 11, be arranged at rolling clamp dish 13, motor 15, the belt 17 of base plate 11 and be arranged at first keeper 18 and second keeper 19 of rolling clamp dish 13 relative both sides.The base plate 11 that is used for the fixture for laser welding 10 of cylindrical battery can weld to cooperate plumb joint along orthogonal direction activity in horizontal plane.
Said first keeper 18 and second keeper 19 are along the said cylindrical battery of axial location of said rolling clamp dish 13, and said belt 17 is movably connected on said motor 15 and rolling clamp dish 13, and said rolling clamp dish 13 rotates under said motor 15 drives.Said first keeper 18 and second keeper 19 are cylinder, and said first keeper 18 and second keeper 19 move to support the cover plate of the said cylindrical battery in location towards said rolling clamp dish 13.It is understandable that one in first keeper 18 or second keeper 19 can fixedly install.In the present embodiment, first keeper 18 and second keeper 19 are arranged on the support bar 20 and corresponding clip is held in the cylindrical battery in the rolling clamp dish 13.
The fixture for laser welding that is used for cylindrical battery 10 of the utility model adopts mechanical positioning, increases welding reliability, improves solder yield, improves automaticity when the cover plate to the cylindrical battery two ends welds.
Above content is the further explain that combines concrete preferred implementation that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection domain of the utility model.
