The specific embodiment
The utility model is described in further detail below in conjunction with Figure of description.
As shown in Figure 1, 2, a kind of battery pole piece coating thickness closed-loop control system comprises unwinding device 1 and the feeding device of being located at head, is located at middle drying unit 6, and is located at the wrap-up 8 of tail.Described feeding device comprises scraper 3, paint roller 2, back flow roll 4 and slurry vessel 12, be provided with slip in slurry vessel 12, paint roller 2 rotations also take up slip, control the thickness of paint roller 2 surface coatings by controlling scraper 3 and the spacing of paint roller 2, and the coating on last paint roller 2 is transferred on pole piece 11 at last.Described head is provided with the first laser thickness gauge 5 between described feeding device and described drying unit 6, described tail is provided with the second laser thickness gauge 7 between described wrap-up 8 and described drying unit 6, described first and second laser thickness gauge 5,7 signal feedback are in PC 9, described PC 9 is by USB change-over switch amount interface and described PLC control cabinet 10 connecting communications, and PLC control cabinet 10 is controlled elevating mechanism (not indicating) action; Described elevating mechanism comprises servomotor, the lower skewback that is connected with described servomotor output shaft and the upper skewback that coordinates with described lower skewback inclined-plane, being erected on described upper skewback of described scraper 3.
Operation principle of the present utility model is as follows:
1, the real time data that automatically records according to laser thickness gauge by calibrator software of PC is carried out the mean value calculation of every film and the analytic method of weighted average, obtain the weighted average thickness of nearest 20 films, and result of calculation and the data that record are recorded in database;
2, take the thickness of tail dry film as standard, scraper 3 with head is regulated coating thickness, whether surpass by the weighted average thickness that judges continuous 3 of dry film and control the variation tendency that limit judges thickness, if continuous 3 transfinite, the ratio of analyzing immediately the weighted average thickness of head wet film and dry film weighted average thickness is determined the toolsetting ratio K value of scraper 3, suppose that dry film exceeds 5 microns of standards, so head wet film toolsetting amount T=K*5 micron; Thereby be adjusted in exactly near standard intermediate value (calculate the impact of removing simultaneously base material thickness, before namely asking the K value, first deduct the base material thickness of setting on software, then ask ratio K);
3, as shown in Figure 3, after calibrator software calculates toolsetting amount T, turn switch card by USB and convert the toolsetting amount to T switching value pulse signal to the PLC control cabinet; The toolsetting enable signal sends prior to the toolsetting pulse, and the toolsetting amount of the corresponding wet film of toolsetting rising edge of a pulse number adds thick film surface if upper toolsetting enable signal sends expression, on the contrary the attenuate face;
4, as shown in Figure 4, head PLC receives the high level signal of toolsetting enable signal and the rising edge signal of toolsetting pulse, and the toolsetting action could be identified and carry out to the pulse that satisfies condition;
5, scraper 3 thickness are controlled in lifting skewback by servomotor and are controlled, scraper 3 is placed on skewback, when PLC control servomotor pulls or promotes lower skewback, upper skewback will move, scraper 3 is moved up and down, thereby regulate the thickness of face, and feed back the actual act amount by displacement transducer and mate the toolsetting amount, make program control amount and practical adjustments amount consistent.
