Embodiment
As shown in Figure 1, a kind of cylindrical battery internal resistance auto testing instrument comprises frame 1, and feeding warehouse 2 is arranged at frame 1 top.As shown in Figure 2, the surrounding of feeding warehouse 2 by baffle plate, wherein two baffle plates 201 of bottom are for being obliquely installed the formation discharging opening.Going out feed bin 2 belows has ratchet 3, and the side face of ratchet is used to take away the battery in the feeding warehouse 2 near discharging opening.For this reason, the side face of ratchet 3 is got hopper 301, near have its coaming plate 302; Prevent that battery from dropping from getting hopper 301, in ratchet 3 rotation processes, battery can fall into automatically to be got in the hopper 301; Because it is closeer to get hopper 301 settings, and discharging opening is bigger, each ratchet 3 can be got two batteries.
This auto testing instrument also comprises the resistance-meter 4 with two testing needles 400, and resistance-meter can adopt traditional structure, and is as shown in Figure 3, and its two testing needles 400 are located at the both sides of ratchet 3, and each other over against (wherein a testing needle is not shown in the drawings).But two testing needles 400 drive move toward one another by cylinder 401, and test is accomplished in the end, two ends of the battery of can conflicting when finally detecting.
Because the spacing between testing needle 400 and the battery end can't accurately be controlled; If testing needle is too near ratchet 3; Then finally can cause cylinder to apply excessive pressure to testing needle; Cause testing needle 400 to fracture, so present embodiment is fixed on cylinder 401 on the slide block 402 of a slide mechanism, the guide rod 404 that runs through 402 slide block 402 is arranged on the slide 403; Slide block 402 has buffer spring 405 back to guide rod 404 upper sleeve throughs between ratchet 3 one sides and the slide 403, can avoid testing needle 400 to be fractureed.
The present embodiment auto testing instrument also comprises control gear; Propulsion system and cylinder 401 that this control gear major control driving pawl 3 rotates; Propulsion system mainly are made up of stepper motor 302 and gear train; Utilize stepper motor 302 can drive ratchet 3 and rotate, and the certain hour that can after rotating equal angular, pause.
In order to write down the internal resistance of each battery, the present embodiment tester has also been installed and has been swept the ink recorder structure, and this is swept the ink recorder structure and comprises and sweep yard device 501, sweeps yard device 501 and faces near the coaming plate 302 ratchet 3 side faces, and scanning window 303 is arranged on the coaming plate 302.Owing on the battery bar code is arranged; Can discern battery and record is carried out in the internal resistance of each battery through sweeping yard device; Because battery is to fall at random to get in the hopper 301; Bar code not necessarily over against sweeping yard device 501, therefore need be provided with the motor 502 that output shaft has electromagnetic performance in a side of ratchet 3, and motor 502 is driven and can be moved to ratchet 3 by cylinder 503.The position of sweeping the output shaft sensing ratchet 3 of yard device 501 and motor 502 is consistent; When battery pauses in this position; Cylinder 503 pushing motors are near ratchet 3, and the output shaft energising holds battery one end end, in the rotation process; Sweep yard device 501 and read the bar code on this battery, discern and write down this battery.
As shown in Figure 2, ratchet 3 belows are provided with defeated material slideway 600, and defeated material slideway 600 is horizontally disposed with, and the discharge end downwarping is provided with travelling belt in the horizontal segment.As shown in Figure 5, vertically there are two 601,602, two pushing blocks of pushing block that insert into the inner portion to drive near the section by cylinder 603, battery is dropped one by one.In order to block battery better, pushing block is a cambered surface facing to an end end face of defeated material slideway 600.
Shown in Fig. 6～9, the sidepiece of frame 1 has material collecting device, and this material collecting device comprises the rewinding slideway 701 of a plurality of parallel arranged; The rewinding slideway is divided into two sections; One section is horizontally disposed with, and the inner rotating band 702 that is driven by same motor 715 that is provided with, and another section is downward-sloping setting.Rewinding slideway feed end has horizontally disposed substrate 703, and slide unit 704 that is slidingly matched with it and the driving mechanism that drives the slide unit slip are arranged on the substrate 703.Driving mechanism comprises motor 714, power wheel, driving-belt 705 and driving-chain 706, wherein driving-chain 706 and slide unit 704 snap fit.
The principle of work of said apparatus is following:
Shown in figure 10, battery 8 is placed in the feeding warehouse 2, starting switch 9; Stepper motor 302 rotates through gear train 1 driving pawl 3, and after ratchet 3 turned an angle, certain hour can pause; This moment, battery 8 fell into vacant getting in the hopper 301, and ratchet 3 is rotated further.
In this tester, the spacing between motor 502 and the testing needle 400 equals two spacings of getting hopper 301, therefore when battery 8 turns to the position of motor 502 and testing needle 400; Ratchet pauses, and cylinder 503 drive motor 502 are near ratchet, and the output shaft of motor 502 holds battery 8; Motor 502 rotates battery 8; In the rotation process, sweep yard device and read the bar code on the battery, battery is discerned.This moment, cylinder 401 drove the conflict end of last battery of testing needles, detected its internal resistance, so just can carry out record to the internal resistance of each battery.
Material collecting device mainly is the difference according to the internal resistance of cell, and cell classification is packed in each magazine 713.Because ratchet 3 belows do not have coaming plate; Battery falls in the rewinding slideway 600 automatically, because the driving of travelling belt, cell row proceeds to the discharge end of rewinding slideway 600; Because stopping of pushing block 601,602; Battery stops herein, and pushing block 601,602 is clamped a battery respectively, can guarantee that battery falls in the material collecting device one by one.
Because battery is to fall in order in the defeated material slideway 600, and control gear can discern the internal resistance of each battery, and therefore, slide unit 704 can be transported to battery the feed end of corresponding rewinding slideway according to the difference of the internal resistance of cell.The battery that falls from defeated material slideway 600 gets in the receiving vat 707, owing to stopping of lever 710, in slide unit 704 moving process, above battery can rest on.When moving to corresponding rewinding slideway place, air cylinder driven lever 710 shrinks, and battery falls into rewinding slideway 710, finally falls in the rewinding box 713.
All motors, cylinder and the resistance-meter of present embodiment tester all is by control box 10 controls; Control box 10 inside are provided with memory storage; Can store the internal resistance data of all batteries, can the battery branch be installed in the different rewinding boxes high efficiency according to the internal resistance data in addition.
