Description
Technical field
This utility model relates to technical field of lithium batteries, is specifically related to a kind of for cylindrical lithium battery group laser welding
Positioner.
Background technology
Multiple lithium batteries through PACK in groups after, need many lithium batteries are carried out series and parallel according to certain mode
Get up, to complete the making work of a module.And the series and parallel work of individual module, it is first red copper pole piece to be welded on often
On battery core pole, then red copper pole piece is carried out series and parallel.Its working method mainly battery core load module box in groups after,
One piece of red copper pole piece is placed on one face of battery, uses laser-beam welding machine by lug each on red copper pole piece and corresponding battery pole
Post firmly welds together, and welds another face of module in the same way, thus realize this module after the welding of this face
Connection in series-parallel work.But due to modular cartridge headspace so that existing modular cartridge or without pole piece location measure, or have one
The locating dowel of a little symbolistic fragilities so that red copper pole piece location difficulty, when welding, red copper pole piece is easily wrong with corresponding battery
Position, causes on unwelded, results in more defective products.Thus it is right to have to first go to position red copper pole piece with substantial amounts of adhesive tape
After weld again, and cause that labor intensity is big, production efficiency is relatively low.
Utility model content
For the deficiency in existing cylindrical lithium battery group laser welding, this utility model provides one for cylindrical lithium
The positioner of set of cells laser welding, improves welding efficiency and welding quality.
For solving above-mentioned technical problem, this utility model adopts the following technical scheme that
A kind of positioner for cylindrical lithium battery group laser welding, including base plate, described base plate is arranged over using
In the pressure rings positioning the pole piece in lithium battery group, one end of described base plate is installed with support column, described support column
Top is installed with regulation bolt, and the top of described regulation bolt is installed with the pressure head for fixing described pressure rings.
Scheme further, described base plate is L-type structure, and described support column is installed in the horizontal segment of base plate, described pressure rings
It is installed in the vertical section of base plate.
Scheme further, the material of described pressure rings is isolation material.
First pass through the height of twisting regulation bolt so that it is height adapts to the height of lithium battery module；Then by be welded
Red copper pole piece is placed on battery modules relevant position, pushes down red copper pole piece with the dual-side of pressure rings and makes it be relatively fixed at lithium
In battery modules, then it is manually pressed by regulating the pressure head of bolt end head so that it is clasp the bottom of pressure rings, thus pressure rings fastened
Battery modules positions, will be compacted in battery modules by red copper pole piece, it is to avoid red copper pole piece is sent out in battery modules
Raw skew, thus facilitate follow-up welding operation.
Described base plate is L-type structure, i.e. facilitates and fixes support column and pressure rings, makes them become an entirety, also
Be conducive to lithium battery module is subjected to, make lithium battery module be relatively fixed the horizontal segment of base plate and vertical section it
Between, improve the stability of welding operation.
Pressure head of the present utility model Height Adjustable, significantly improves work efficiency；Firm position is higher, pressure rings
Crimping closely knit, welding quality is high, operates comfortable, convenient and swift, single can complete operation；Whole tool structure is simple, becomes
This is relatively low, has good exploitativeness.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the side view that positioner of the present utility model acts in battery modules.
In figure: 1-base plate, 2-pressure rings, 3-support column, 4-regulates bolt, 5-pressure head, 6-battery modules.
Detailed description of the invention
Below in conjunction with the accompanying drawings a kind of preferred implementation of the present utility model is described in detail.
As it is shown in figure 1, a kind of positioner for cylindrical lithium battery group laser welding, including base plate 1, described base plate
1 is arranged over the pressure rings 2 for positioning the pole piece in lithium battery group, and one end of described base plate 1 is installed with support column
3, the top of described support column 3 is installed with regulation bolt 4, and the top of described regulation bolt 4 is installed with for fixing described pressure
The pressure head 5 of ring 2.
Scheme further, described base plate 1 is L-type structure, and described support column 3 is installed in the horizontal segment of base plate 1, described pressure
Ring 2 is installed in the vertical section of base plate 1.
Scheme further, the material of described pressure rings 2 is isolation material, thus it does not affect laser welding operation, simultaneously
Owing to its material is harder, it is not easy to deformation, can well push down red copper pole piece.
During use, as in figure 2 it is shown, lithium battery module 6 is placed on base plate 1, by the height of twisting regulation bolt 4,
Its height is made to adapt to the height of lithium battery module 6；Then red copper pole piece to be welded is placed on battery modules 6 relevant position
On, put down by pressure rings 2 and make its dual-side push down red copper pole piece, then be manually pressed by regulating the pressure head 5 on bolt 4 top so that it is
Clasp the bottom of pressure rings 2, so that pressure rings 2 is pressed on the red copper pole piece in battery modules 6, it is achieved red copper pole piece is determined
Position, will be compacted in battery modules 6 by red copper pole piece, it is to avoid red copper pole piece offsets in battery modules 6, thus facilitates
Follow-up welding operation.
Upper described embodiment is only to be described preferred implementation of the present utility model, not new to this practicality
The scope of type is defined, and on the premise of without departing from this utility model design spirit, those of ordinary skill in the art are to this reality
The various deformation made by novel technical scheme and improvement, all should fall into the protection that claims of the present utility model determine
In the range of.
