Background technology
By laminated clapboard on multiple positive plate, stacked negative plate on dividing plate, stacked positive plate again above the dividing plate on negative plate, and the mode again stacking gradually dividing plate and negative plate is to manufacture secondary cell.On the other hand, the active material determining polarity is coated with on the two sides in order to manufacture secondary cell and stacked each pole plate.That is, be coated with positive active material on the two sides of positive plate, be coated with negative electrode active material on the two sides of negative plate.
Therefore, dividing plate is got involved between positive plate and negative plate, manufacture by multiple positive plate and negative plate (following, for the ease of understanding, positive plate and negative plate are referred to as " pole plate ") electrode assemblies of stacked regulation area, and this electrode assemblies is contained in shell (case), thus manufacture the battery unit (cell) being injected electrolyte by the opening portion, side of shell to enclosure, the opening portion, side of sealed cell unit (cell) after completing discharge and recharge by the battery unit (cell) to this secondary cell, carry out the manufacture of secondary cell.
Punching press (stamping) can be used to equip and to manufacture this positive plate and negative plate.That is, untie the negative or positive electrode electrode being wound into roll forming state with constant speed, generate electrode with grid (grid), and after cutting into constant size, be loaded into feeding portion.This pole plate manufacture process also can comprise pole plate matting and pole plate checks operation.When comprising inspection operation, the pole plate manufacturing invariant shape is positioned over conveyer top, to the transfer of inspection operation, and by being arranged at the testing fixture on pole plate top through checking process.If checking process terminates, then defective products is removed, and excellent product are transferred to loading part, and in order to remove defective products or load excellent product, most preferably, transfer in the mode be attached to below conveyer.Therefore, the part illustrated in the present invention is transfer conveyor section to loading part transfer and loading station, and all process steps part till eliminating checking process.
Now, along transfer line transferring pole plates, and when above-mentioned pole plate is landed to storehouse feeding portion, tilting degree due to the rearward end side of pole plate is greater than the tilting degree of the leading section side of pole plate, thus pole plate advances in an inclined state, and load to the landing of storehouse feeding portion, instead of land immediately below storehouse feeding portion.
On the other hand, along transfer line (namely, conveyer belt) transferring pole plates, and when above-mentioned pole plate is landed to storehouse feeding portion, owing to remaining the power of the direction of advance promoting pole plate to transfer line, the tilting degree of the rearward end side of pole plate is made to be greater than the tilting degree of the leading section side of pole plate, thus pole plate advances in an inclined state, instead of land immediately below storehouse feeding portion, if use up the power so promoting pole plate, then pole plate loads to the landing of storehouse feeding portion by deadweight.
But, like this, pole plate advances to transfer direction and in the process of landing under the state that rear side tilts a little and front side is sagging a little, the power that forward direction promotes pole plate is not suitably decayed, thus the situation that the frequent end that pole plate occurs collides with storehouse feeding portion because of excessive power, like this, if pole plate advance and landing and the end of pole plate because of excessive power with storehouse feeding portion (precisely, the internal face in storehouse feeding portion) collide, then cause the phenomenon of the active material fragmentation being coated on pole plate two sides (particularly, the phenomenon of a part of active material fragmentation of the end side collided with storehouse feeding portion in whole of active material), like this, if in the process of loading pole plate, active material is broken and damage, the characteristic of pole plate itself is then likely caused to decline, thus, finally likely bad impact is produced on the performance of secondary cell.Just, if the end of pole plate collides with storehouse feeding portion by excessive power, then produce the phenomenon of the active material fragmentation of pole plate, in addition, also likely produce much bad impact, thus current, need transferring and loading in the process of pole plate, can prevent in advance the end section of pole plate excessively and the suitable buffering of phenomenon that collides of storehouse feeding portion load guidance unit.
In fluting is equipped at a high speed, because the screen of pole plate is exceedingly fast, if thus load pole plate in moving process, then collide with face, storehouse feeding portion and the corner of pole plate is badly damaged.
Therefore, load under not impaired state to make pole plate, need the speed reducing pole plate, and the unit like this suitably reducing pole plate speed is incomplete in the past, thus current, in raising speed of production, the impaired problem of pole plate has become maximum stumbling-block, and the life-span or the performance that are reduced pole plate by the impaired broken thing caused of pole plate owing to likely occurring in the process of loading pole plate, not thus fine in a lot.
