Description
Technical field
The utility model relates to technical field of lithium ion more particularly to a kind of positive and negative tab of rectangular lithium ion battery are super
Sonic soldering connects intensity detecting device.
Background technique
Connection in producing line between tab and cover board at present is by ultrasonic welding mostly by the connection on tab and cover board
Piece welds together.In lithium ion battery manufacturing process, the welding quality of tab and cover board can have very the performance of lithium battery
It is big to influence, if tab not with connection sheet it is unwelded internal resistance is excessive to together, just will appear, the too small or breaking feelings of electric current
Condition generates bad battery.If weld strength is excessive, tab is be easy to cause to cause tab to be broken in the lower part of weldering print, fracture
Tab is connect with another electrode, will cause battery short circuit even it is on fire, there are serious security risks.So detection tab with
Weld strength between cover board becomes very necessary.
Utility model content
To solve technical problem present in background technique, the utility model proposes a kind of rectangular lithium ion battery positive and negative anodes
Ear ultrasonic welding intensity detecting device.
The utility model proposes a kind of positive and negative tab ultrasonic welding intensity detecting device of rectangular lithium ion battery, comprising:
Weld case, driving mechanism, soldering tip and welding platform；Welding platform is equipped with supporting surface, and driving mechanism is connect with weldering case, and soldering tip is connected to
In driving mechanism and soldering tip is located above supporting surface, and driving mechanism driving soldering tip just moves up and down on the support surface, soldering tip
Equipped with the range sensor for detecting soldering tip to height between supporting surface.
It preferably, further include warning device, warning device is mounted on weldering case, and is connect with height sensor.
Preferably, supporting surface is horizontally disposed plane.
Preferably, weldering case is equipped with display screen.
In the utility model, the positive and negative tab ultrasonic welding intensity detecting device of the rectangular lithium ion battery proposed is avoided
Quality problems and security risk are brought because of micro- contact, that is, rosin joint of connection sheet on tab and cover board；It reduces simultaneously bad
The productivity of product improves the production efficiency of qualified products, has effectively saved raw material and production cost.
Detailed description of the invention

Structural schematic diagram.
Fig. 2 is the structural schematic diagram of to-be-welded pieces normal weld.
Fig. 3 is the structural schematic diagram of to-be-welded pieces abnormal solder.
Specific embodiment
As shown in Figure 1-3, Fig. 1 be the utility model proposes a kind of positive and negative tab ultrasonic welding of rectangular lithium ion battery it is strong
Spend the structural schematic diagram of detection device.Fig. 2 is the structural schematic diagram of to-be-welded pieces normal weld.Fig. 3 is that to-be-welded pieces are welded extremely
The structural schematic diagram connect.
Referring to Fig.1-3, the utility model proposes a kind of positive and negative tab ultrasonic welding intensity detection of rectangular lithium ion battery
Device, comprising: weldering case 1, driving mechanism 2, soldering tip 3 and welding platform 4；Welding platform 4 is equipped with supporting surface, driving mechanism 2 and weldering
Case 1 connects, and soldering tip 3 is connected in driving mechanism 2 and soldering tip 3 is located above supporting surface, and driving mechanism 2 drives soldering tip 3 supporting
It is moved up and down above face, soldering tip 3 is equipped with the range sensor for detecting soldering tip 3 to height between supporting surface.
The positive and negative tab ultrasonic welding intensity detecting device of the rectangular lithium ion battery of the present embodiment in specific work process,
It is then that mounted to-be-welded pieces are horizontal between two connection sheets 7 that the tab 5 of lithium ion battery is placed on cover board 6
It places on the support surface；Wherein positioned at the bottom surface of standard weldment bottom tabs 7 to the mark between the top surface of top connection sheet 7
Quasi- distance is set as D；Starting driving mechanism 2, driving soldering tip 3 declines, when soldering tip 3 reaches at the top of to-be-welded pieces, stop decline, Gu
Determine 3 position of soldering tip, soldering tip 3 is set as D to the actual range between supporting surface at this time1；Start range sensor, range sensor pair
Soldering tip 3 is detected to the actual range between supporting surface；Work as D1When equal to D, belong to normal weld, starting weldering case 1, soldering tip 3
To-be-welded pieces are welded, welding finishes, and closes weldering case 1, and driving mechanism 2 drives soldering tip 3 to rise, and resets, and removes weldment；
Work as D1Less than D, or be greater than D when, belong to abnormal solder, this weldment do not welded.
In the present embodiment, the positive and negative tab ultrasonic welding intensity detecting device of the rectangular lithium ion battery proposed uses
The mode of range sensor is set in soldering tip 3, the actual conditions of to-be-welded pieces are determined before welding；Work as to-be-welded pieces
It when determining qualified, then is welded, avoids and bring quality because of the micro- contact i.e. rosin joint of connection sheet 7 on tab 5 and cover board 6
Problem and security risk；The productivity for reducing defective products simultaneously, improves the production efficiency of qualified products, has effectively saved original
Material and production cost.
In a specific embodiment, the positive and negative tab ultrasonic welding intensity detecting device of the rectangular lithium ion battery also wraps
Warning device is included, warning device is mounted on weldering case 1, and is connect with height sensor, when soldering tip 3 to the reality between supporting surface
Distance D1Less than gauged distance D, or when being greater than D, warning device will be will call the police, to remind staff that soldering tip 3 is timely
It resets, to-be-welded pieces is not welded, improve welding and detection efficiency.
Further, supporting surface is horizontally disposed plane, guarantees the essence that soldering tip 3 is detected to actual range between supporting surface
True property.
Further, weldering case 1 is equipped with display screen for showing soldering tip 3 to the actual range between supporting surface.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
