Feature of the present invention and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.
Embodiment
As illustrated in fig. 1 and 2, among a kind of embodiment, the rectangular cell single chip type tunable winding needle construction comprises contiguous block 1, connector 2, adjusts piece 3 and volume pin 4.Volume pin 4 comprises that first needle body 401 that lays respectively at upper and lower among the figure and the needle handle of second needle body, 402, the first needle bodies 401 and second needle body 402 offer installing hole respectively, and each installing hole embeds respectively adjusts piece 3.Connector 2 adopts pin 2, and an end of pin 2 is fixed in the positioning hole of adjusting on the piece 3, and the other end of pin 2 is installed in the connecting hole interior (not shown) on the contiguous block 1.To adjust piece 3 by pin 2 and be connected, the needle handle of first and second needle body of volume pin 4 is fixed on the contiguous block 1 with contiguous block 1.The connecting hole that pin 2 is installed on the contiguous block 1 adopts fixed dimension, and the positioning hole of adjustment piece 3 can select to adopt different eccentric forms, is convenient to reach the coiling requirement of different electric cores.Adjust interval between first and second needle body by the adjustment piece 3 of selecting to have disposed suitable positioning hole, can reach required volume pin width.For example, when having the adjustment piece 3 of position, different hole, replacing can carry out trace adjustment to the width of volume pin 4.Volume pin width is meant the integral width after the volume pin installs, it is the desired volume pin of the volume core width of battery size correspondence, volume pin width is decided according to the girth of the electric core that will roll out, and the width side by side that one chip of the present invention is rolled up two needle bodies of pin has determined the girth of the electric core that winds.
Further, installing hole on the needle handle is preferably square, adjust piece 3 should be mutually square with needle handle on installing hole adaptive, positioning hole on the adjustment piece 3 passes the pin 2 and the adaptive installation of aperture of adjusting piece 3 of the pin hole on the contiguous block 1 for being the aperture of eccentric size with respect to the location dimension of adjusting piece 3.
In certain embodiments, comprise that also being arranged on volume pin 4 other end relative with needle handle is the locating piece 6 at pin mouth place, locating piece 6 is fixed on the pin mouth axle 7, locating piece 6 is provided with the location notch that inserts for volume pin 4, first needle body 401 and second needle body 402 insert in the locating piece 6 corresponding location notchs, play the effect of further location volume pin 4.The size of locating piece 6 and adjustment piece 3 is to corresponding, and wherein, the position of location notch is to dispose in the position of adjusting on the piece of offering according to positioning hole.At the required width of volume pin 4, locating piece 6 can be changed to adapt to the coiling requirement of different in width corresponding to adjusting piece 3.Like this, by changing the adjustment piece 3 and the locating piece 6 of different size, reach adjustment to volume pin 4 width.
In a preferred embodiment, also comprise the elastic component that is arranged in the contiguous block 1, elastic component is fixedly installed on the outside left on the top of volume pin needle handle, props up first and second needle body 401,402, makes first and second needle body 401,402 be subjected to the elastic component effect and is the slope trend of drawing close gradually each other.Preferably, contiguous block 1 is provided with the elastic component placement hole that an end is opened, the elastic component placement hole open that be connected to the top of needle handle, elastic component comprises adjusting pin 9 and the spring 10 that places in the elastic component placement hole, an end of regulating pin 9 contacts with the top of needle handle, and the other end of adjusting pin 9 is step-like and mounting spring 10 thereon.The elastic component placement hole is that screw 8 and lock have screw 11 away from an end of needle handle.
During work, volume pin 4, adjustment piece 3 and the elastic component with corresponding size is installed on the contiguous block 1 as required, and the width of volume pin 4 is adjusted by selecting suitable adjustment piece 3 for use.As shown in Figure 2, when implementation is threaded a needle, volume pin 4 application of forces are overcome the active force of spring 10, make volume pin 4 be in level, promptly first and second needle body 401,402 is in parastate, and will roll up in the location notch that 4 pairs on pin is inserted into locating piece 6 by the motion of contiguous block 1.As shown in Figure 2, when carrying out drawn needle, contiguous block 1 drives volume pin 4 and recesses locating piece 6 under equipment operation, and volume pin 4 returns to the inclined-plane state under the effect of spring 10.So just make volume pin 4 when drawn needle, not have influence on the volume core, thereby can guarantee the quality and the precision of the volume core of manufacturing well.
Shown in Fig. 2 to 4, in further embodiments, also comprise adjustment part 5, adjustment part 5 has from its front end toward the rear end by the narrow shape that broadens, and may command is inserted between first and second needle body to adjust first and second needle body gradient from its front end.Preferably, the front end of adjustment part 5 is taper, and the rear end is threaded cylindricality, for example is common machine-processed rice screw, and contiguous block 1 offers the screw of the adjustment part 5 that is used to pack into, and adjustment part 5 places in this screw and can precession or back-out by threaded engagement.By regulating the position of adjustment part 5, can adjust the width of volume pin 4 opening parts, be beneficial to adapt to when threading a needle to rolling up the requirement of pin 4 width with drawn needle.During drawn needle, volume pin 4 breaks away from locating piece 6, and first and second needle body comes closer under the effect of spring 10, volume pin size decreases, but, maintain an appropriate gap between first and second needle body and can not close up fully because the effect of adjustment part 5 makes at first and second needle body opening part.Keep an appropriate gap and the electric core of spooling is easy to and rolls up pin and break away from, and make the volume pin run into barrier film, made things convenient for the quality of the electric core of threading a needle and further having guaranteed to wind at the Shi Buhui that threads a needle next time.Preferably make adjustment part 5 first and second needle body is adjusted to the angle that has about 2 °.
Rectangular cell single chip type tunable winding needle construction of the present invention can be used for the coiling of (but being not limited to) lithium ion battery cell.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
