Specific embodiment
As shown in Fig. 1 ~ 7, a kind of lithium coin cells pre-arcing fixture, including rack 10,10 upper end of rack is provided with gas
Cylinder 20 is provided with upper fixture 30 in 21 lower end of piston push rod of cylinder 20, lower fixture 40 is provided with below upper fixture 30, upper
30 lower end surface of fixture and lower 40 upper surface of fixture are provided with conductive contact 50, and 10 rear end of rack is provided with resistance 60, in resistance 60
Conducting wire 61 is provided between conductive contact 50.The raising and lowering that can control upper fixture 30 by cylinder 20, passes through conduction
Connector 50, conducting wire 61, resistance 60 can form discharge loop with lithium coin cells 81, discharge lithium coin cells 81.
In the present embodiment, the left and right sides of lower fixture 40 and rear side are provided with postive stop baffle 70.Pass through postive stop baffle 70
Mounting plate 80 can be limited, make mounting plate 80 after placing, lithium coin cells 81 can be a pair of with conductive contact 50 1
It answers.
In the present embodiment, the conductive contact 50 includes fixes sleeve 51, and setting can be relatively fixed in fixes sleeve 51
The compression leg 52 that sleeve 51 slides axially, is provided with spring 53 in fixes sleeve 51, and 53 one end of spring is fixed on fixes sleeve
On 51,53 other end of spring is fixed on compression leg 52.Conductive contact 50 is arranged to by fixes sleeve 51, compression leg 52, spring 53
Composition, compression leg 52 are being ejected by the thrust of spring 53 under normal conditions, and when the end of compression leg 52 is under pressure, compression leg 52 can be along axis
It is moved in fixes sleeve 51, makes conductive contact 50 that integrally there is retractility, convenient in conductive contact 50 and lithium coin cells
When 81 contact, guarantee that each lithium battery on mounting plate 80 is contacted with conductive contact 50.
In the present embodiment, the guide post 11 extended downwardly is provided in 10 upper end of rack.
In the present embodiment, the guide hole 31 cooperated with guide post 11 is provided in the upper end of upper fixture 30.Guide post 11 and guide hole 31
Cooperation, upper fixture 30 can be oriented in upper fixture 30 during raising and lowering.
Specific implementation process:
(1) under normal conditions, cylinder 20 is shunk, and the distance between cope plate and lower template are maximum, and selecting voltage is 3.5V's
Lithium coin cells 81, it is 20 ohm of resistance 60 that corresponding resistance 60, which selects resistance value, when needing to carry out to lithium coin cells 81
