Description
Technical field
This utility model belongs to the barrier film field of fixation devices of battery diaphragm production, and in particular to a kind of Magnetic Control
Scalable needle plate mechanism.
Background technology
The severe energy and environment challenge makes the transition of transportation and energy's power become global common recognition, and automotive engineering has welcome power
The epoch of system electrical.As the burst of power lithium-ion battery demand increases, lithium ion battery separator demand also welcomes
" blowout ".Battery diaphragm directly affects the safety of battery, energy density and makes as one of the critical material of lithium ion battery
Use the life-span.
In the production technology of lithium ion battery separator, the stability and safety of barrier film need to be lifted by heat treatment step
Property, it is ensured that the capacity of lithium ion battery is evenly distributed, and self discharge is reduced, and improves security performance and cycle life.
Heat treatment step is that the needle plate allowed on chain fixes barrier film so that barrier film follows chain by baking oven, finally departs from
The process of needle plate.Often because the projection length of pin body is fixed on needle plate in production, in baking oven, barrier film is to contract
Greatly, when needing larger fixing force, because pin body penetrates depth not enough, barrier film is caused to depart from needle plate；And baking oven outlet need by
Barrier film is de- with needle plate point and winds, excessive because of depth is penetrated on the contrary, barrier film gap, or even film breakage is caused, just because of pin sheet
Body insertion depth cannot be adjusted, it is impossible to adapt to change needs of the different workshop sections to fixing force so that barrier film production has waste product, shadow
Ring conforming product rate.
Utility model content
In order to solve above-mentioned problems of the prior art, this utility model provides a kind of magnetic control to this utility model
The scalable needle plate mechanism of system, can be adjusted flexibly the projection length of pin body on needle plate, adjust needle plate fixing force, reduce chain
Stress so that production is smooth, it is ensured that the quality of production.
This utility model adopt concrete technical scheme be：
A kind of scalable needle plate mechanism of Magnetic Control, including the pin sheet that needle plate is vertical with the upper surface of needle plate and fixed
Body, has additional movable plate above needle plate, through hole is provided with the plate face of movable plate, and pin body is with through hole suit and sliding is matched somebody with somebody
Close, lifting apparatus are additionally provided between described movable plate and needle plate, movable plate forms vertical side by lifting apparatus and needle plate
To flexible connection.
Described lifting apparatus include the spring being arranged between movable plate and needle plate, and described spring is sleeved on pin body
On.
Described lifting apparatus also include being fixedly installed on the magnetic block of movable plate lower surface, and the height of magnetic block is more than bullet
The elemental height of spring.
Described magnetic block is symmetricly set on the both sides of pin body, and magnetic block lower surface place plane is parallel with needle plate.
The beneficial effects of the utility model are：
This utility model, the movable plate set up is lifted using retractor device so that movable plate can along pin body to
Upper lifting or retracted downward, realize whereby the regulation of pin body projection length, when barrier film is produced, to adapt to different works
Change of the section to fixing force needs, and improves qualification rate.

In accompanying drawing, 1, needle plate, 2, pin body, 3, movable plate, 4, spring, 5, magnetic block.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail：
Specific embodiment, as shown in figure 1, this utility model is a kind of scalable needle plate mechanism of Magnetic Control, including pin
Vertical with the upper surface of the needle plate 1 and fixed pin body 2 of plate 1, the top of needle plate 1 has additional movable plate 3, the plate face of movable plate 3
On be provided with through hole, pin body 2 is with through hole suit and sliding coordinates, and between described movable plate 3 and needle plate 1 lifting is additionally provided with
Device, movable plate 3 forms the flexible connection of vertical direction by lifting apparatus and needle plate 1.
When in use, flexible needle plate mechanism disclosed in the utility model needs to be arranged on the chain arranged in baking oven,
Barrier film, as chain rotates through baking oven, departs from needle plate after fixing by needle plate after drying, during installation, needle plate and chain
Carrier bar is fixed, as shown in Fig. 2 lifting apparatus are in original state in baking oven, the length of this protrusion of hour hands body 2 is most long, pricks
Enter barrier film depth maximum, now fixing force is most strong, can overcome, during drying barrier film, the needle plate stress increase that diaphragm retracts bring
And then cause the problem of barrier film run-bake-needle fault plate, in baking oven outlet, movable plate 3 is lifted by lifting apparatus, now as shown in figure 3,
Now because barrier film is contacted with the upper surface of movable plate 3, pin body 2 bounces back relative to movable plate so that pin body 2 is inserted
The depth of barrier film is reduced, and needle plate fixing force reduces, and is conducive to run-bake-needle fault plate, and gap, film breakage risk is greatly reduced, and improves production qualified
Rate.
Further, described lifting apparatus include the spring 4 being arranged between movable plate 3 and needle plate 1, by spring 4
The structure reliability of movable plate 3 is lifted, is easy to manufacture, described spring 4 to be sleeved on pin body 2 or be provided separately with pin body 2
Between movable plate 3 and needle plate 1, spring 4 is provided separately with pin body 2, can reduce device fabrication cost, ease of assembly,
It is easy to safeguard, spring 4 is sleeved on pin body 2, can guarantee that spring 4 resilience and contraction in the predetermined direction, is prevented from out
The problem of existing spring distortion, operational reliability is good.
Further, for convenience lifting apparatus are lifted up, and described lifting apparatus also include being fixedly installed on movement
The magnetic block 5 of the lower surface of plate 3, the height of magnetic block 5 is more than the elemental height of spring 4.In drying plant exit, under chain
Side arranges Magnet, when chain turns to Magnet top, due to the effect that peer repels each other, moves on the jacking movable plate 3 of magnetic block 5,
The depth that barrier film inserts pin body 2 is reduced, so as to facilitate demoulding, by the way of Magnetic Control, it is to avoid frame for movement
Hardware connects so that chain is rotated and will not impacted because of the lifting of movable plate.
Further, in order to avoid in movable plate lifting process and under end state, interim card pin body 2, described magnetic
Block 5 is symmetricly set on the both sides of pin body 2, to ensure balance when movable plate 3 is lifted, it is ensured that barrier film can be slipped smoothly,
Prevent because movable plate 3 deflection cause barrier film to incline, increase demoulding difficulty situation occur, the lower surface place plane of magnetic block 5 with
Needle plate 1 is parallel so that after movable plate 3 is retracted, needle plate is parallel to each other spring 4 with movable plate 3, it is to avoid the deflection of movable plate 3 is made
Bend into pin body 2, it is ensured that operating reliability, facilitate demoulding to be smoothed out, gap, film breakage risk is greatly reduced, improve production
Qualification rate.
