Description
Technical field
A kind of welding tooling is the utility model is related to, specifically a kind of cylindrical battery lug welding fixture for bottom.
Background technology
With social development, the aggravation of environmental pollution and the increasingly depleted of traditional energy, people to environmental protection consciousness it is more next
It is stronger.And there is lithium ion battery many advantages, such as high-energy-density, high voltage platform, small and green self discharge to turn into green
The first choice of the color energy.Lithium ion battery is divided into two kinds of metal-back and flexible package at present, and wherein column lithium ion battery lug needs
To be welded with outer casing bottom, form bottom electric loop, if bottom failure welding, battery is in vibration environment used in the later stage
Central to easily cause high internal resistance, self discharge is excessive；Or open circuit, it the undesirable element such as can not use, so as to reduce the use of battery
In the life-span, scrap in advance.
The content of the invention
For the above-mentioned deficiency of prior art, the utility model provides a kind of compact-sized, welding positioning stablity, jail
Lean on, avoid welding process from damaging lug, improve welding quality, it is ensured that battery cylindrical battery lug bottom welding safe to use
Frock.
The technical solution adopted in the utility model is：A kind of cylindrical battery lug welding fixture for bottom, it is characterised in that：
Including machine frame, soldering tip support, soldering tip, spot welding capillary, installing plate, L-type support, axle sleeve, cross plate screw, spring, cylinder
Pressure head, holding screw, soldering tip support and installing plate are presented down and are arranged on machine frame, are connected and are welded through bonding tip seat below soldering tip support
Head, soldering tip lower section connect spot welding capillary, two L-type supports are symmetrically connected under installing plate, are worn once tight in each L-type support
Determine the axle sleeve of screw radially locking, wear in axle sleeve and connect cylindrical crimp top and cylindrical crimp top is through cross plate screw lock
L-type support or axle sleeve are connected, abutting, which is provided with to wear, between cylindrical crimp lower pressure head and L-type support is connected on circle in the middle part of cylindrical crimp
Spring on rod structure, the point midway that spot welding capillary is located at the cylindrical crimp line of centres in two L-type supports are in by soldering tip branch
Frame or bonding tip seat drive jacking condition.
The soldering tip support lifting is connected on machine frame.
The bonding tip seat is that cylinder lifts connecting seat.
Axle sleeve holding screw is radially fixed in L-type support, and spring is put on cylindrical crimp top, then is through in axle sleeve,
It is fixed on cross head screw in L-type support, when soldering tip is under cylinder lifting connecting seat or under soldering tip support lift action
When pressure, cylindrical crimp DL synchronization, cylindrical crimp has range difference, the pressure head of two first cylindrical crimps with soldering tip
Part is first encountered at the top of half product battery core, soldering tip DL synchronization under cylinder lifting connecting seat effect, is pressurizeed by spot welding capillary
Half product battery core bottom and lug are welded, welding forms welding circuit, completes between half product battery core negative lug and box hat
Weld, the cylindrical crimp under spring spring-force driven dual slides upwards in axle sleeve, is applied at the top of half product battery core box hat
Power uniformity, the impulsive force of cylinder is buffered, it is ensured that the box hat of half product battery core is indeformable, is advantageous to improve welding positioning surely
It is fixed, firm, it is ensured that welding battery quality and service life.
Brief description of the drawings
Fig. 1 is the utility model dimensional structure diagram；
Fig. 2 is enlarged drawing at I in Fig. 1.
In figure：Installing plate 1, L-type support 2, axle sleeve 3, cross plate screw 4, spring 5, cylindrical crimp 6, half product core 7,
Spot welding capillary 8, holding screw 9, soldering tip 10, cylinder lifting connecting seat 11, welding support 12, machine frame 13, lug 14.
Embodiment
It is described further below in conjunction with drawings and examples.
Fig. 1, shown in 2：A kind of cylindrical battery lug welding fixture for bottom includes machine frame 13, soldering tip support 12, soldering tip
10th, spot welding capillary 8, installing plate 1, L-type support 2, axle sleeve 3, cross plate screw 4, spring 5, cylindrical crimp 6, holding screw 9,
Soldering tip support 12 and installing plate 1, which are presented down, to be arranged on machine frame 13, and the lower section of soldering tip support 12 connects through cylinder lifting connecting seat 11
Connect soldering tip 10, the lower section of soldering tip 10 connection spot welding capillary 8,1 time two L-type support 2 of symmetrical connection of installing plate are equal in each L-type support
The axle sleeve 3 radially locked once holding screw 9 is worn, is worn in axle sleeve 3 and connects the top of cylindrical crimp 6 and the top of cylindrical crimp 6
Connection L-type support or axle sleeve is locked through cross plate screw 4, pushes against to be provided with to wear between cylindrical crimp lower pressure head and L-type support and connects
In the spring 5 in the middle part of cylindrical crimp on cylindrical structure, spot welding capillary 8 is located at the cylindrical crimp line of centres in two L-type supports
Point midway be in that jacking condition is driven by soldering tip support or bonding tip seat.
Lug 14 is located at the position between the box hat of 8 and half product battery core of spot welding capillary 7, when lug is outward-dipping or not straight
When, when battery production conveying rotates to welding post, lug revolves along the pressure head outer circumferential profile shape of cylindrical crimp 6
Turn, so as to avoid lug from not damaged in welding process, effectively ensure the stable position welding of lug.
