Here; In this cleaning device 2; For the front end 221 that makes cleaning balde 22 contacts with photosensitive drums 10, wipes from the surface of photosensitive drums 10 down and the residue that reclaims can not leak into outside the cleaning frame support body, and subtend constitutes peripheral part A, peripheral part B and the peripheral part C of the periphery of inlet 210a and applies encapsulant 20 and descended time.
Below, the content shown in the step S1 of detailed description Fig. 6 to peripheral part A, peripheral part B and peripheral part C coating encapsulant.
Figure 10 is the figure that the coating method of encapsulant is shown.Below shown in the coating method of encapsulant be the 1st embodiment of liquid material coating method of the present invention.
Figure 10 shows simple illustrated cleaning frame support body 21 and from the encapsulant blowoff 300 of nozzle 301 ejection encapsulants 20; Wherein, sealing material 20 is by constituting as the thermoplastic elastomer with an example of aqueous coating and the liquid material that solidifies.The performance of this thermoplastic elastomer is as under heated condition, being the function of so-called heat-fusible adhesive aqueous, that solidify through cooling.As other liquid materials, the polystyrene series of can giving an example out material, polycarbamate series material and polyureas series material.
And Figure 10 also shows along with the motion track that cleaning frame support body 21 is applied encapsulant 20, nozzle 301.In addition, in Figure 10, omitted the diagram of inlet 210a shown in Figure 5.In addition in Figure 10, the face that will comprise peripheral part A, peripheral part B and peripheral part C in the periphery of inlet 210a of cleaning frame support body 21 be made as with XYZ coordinate axle shown in Figure 10 in X-parallel face of Y face describe.
In Figure 10 (a); Show the front end that makes nozzle 301 and move to the 1st terminal point D1 from the 1st starting point S1; That is, the front end of nozzle 301 and the Y axle among Figure 10 are moved abreast, come the situation of the peripheral part B coating encapsulant 20 in the periphery of inlet 210a shown in Figure 5.
Figure 10 (b) shows and is being through with after peripheral part 20 applies encapsulant 20; Nozzle 301 is keeping predetermined angle theta (with reference to Figure 11 (b)) on the face parallel with Y-Z face, to move with respect to the Z axle, thereby leaves and move to the 1st situation through some T1 from the 1st terminal point D1.
Figure 10 (c) show move to from the 1st terminal point D1 the 1st through front end and the Y axle of the nozzle 301 of some T1 abreast to the 2nd move through some T2 after, move to the situation of the 2nd starting point S2 abreast with the Z axle again.
Figure 11 illustrates from the negative direction of X axle shown in Figure 10 to observe the figure that move of Figure 10 (a) to the nozzle shown in Figure 10 (c).
Figure 11 (a) shows the front end of nozzle 301 and the Y axle moves to the 1st terminal point D1 abreast from the 1st starting point S1 situation, and the front end that Figure 11 (b) shows nozzle 301 keeps predetermined angle theta on the plane parallel with Y-Z face, to move to the 1st situation through some T1 from the 1st terminal point D1 with respect to the Z axle.Front end and Y axle that Figure 11 (c) shows nozzle 301 move to the 2nd situation through some T2 abreast, and the front end that Figure 11 (d) shows nozzle 301 moves to the situation of the 2nd starting point S2 from the 2nd through some T2.Return Figure 10 and continue explanation.
In Figure 10 (d); That kind according to shown in Figure 11 (d) shows following situation; That is: moved to the front end of the nozzle 301 of the 2nd starting point S2; Move abreast applying encapsulant 20 with the X axle afterwards to peripheral part A, and then through the 3rd through some T3 to the 2nd terminal point D2 move, promptly with Figure 10 in the Y axle move abreast, to apply encapsulant 20 to peripheral part C.Like this, in the assembling of cleaning device 2, when peripheral part A side direction peripheral part D side (upside from Figure 10 is to downside) was mobile, peripheral part B in the periphery of inlet 210a and peripheral part C applied encapsulant 20 at the front end that makes nozzle 301.This application pattern is in order to prevent following situation; That is: owing to the spray volume of encapsulant 20 when beginning to spray and the spray volume when finishing ejection from nozzle 31 ejections there are differences; Therefore; Adopting following method to apply under the situation of encapsulant to peripheral part B and peripheral part C; Promptly before peripheral part A side direction peripheral part D side shifting nozzle 301, bring in the coating encapsulant, before peripheral part D side direction peripheral part A side shifting nozzle 301, bring in the coating encapsulant, can prevent that peripheral part B is different with the abundance of the encapsulant of peripheral part C for the opposing party for a side wherein.
And, in the assembling of cleaning device 2,, need not temporarily stop the ejection of encapsulant like this after peripheral part A applies encapsulant, and then applying encapsulant 20 to peripheral part C.Therefore; Be divided into 2 times with the interval that utilizes the ejection that temporarily stops encapsulant and respectively peripheral part A compared with the situation that peripheral part C applies encapsulant 20, can suppress the variation of the encapsulant abundance at the boundary line place between peripheral part A and the peripheral part C.
In Figure 10 (e), show and be through with after peripheral part C applies encapsulant 20, nozzle 301 keeps predetermined angle theta on the face parallel with Y-Z face, to move to the 4th situation through some T4 from the 2nd terminal point D2 with respect to the Z axle.Like this; In the assembling of cleaning device 2; The front end of nozzle 301 from the terminal point that respectively peripheral portions A and peripheral part C applied encapsulant promptly the 1st terminal point D1 and the 2nd terminal point D2 leave, and to conduct corresponding with these terminal points through point, be viewed as the symmetrical the 1st from peripheral part A and move through a T4 through some T1 and the 4th.And; At these the 1st terminal point D1 and the 2nd terminal point D2, promptly be viewed as symmetrical position from peripheral part A; Stop the ejection of encapsulant; Near the 1st terminal point D1 coating amount and near the encapsulant that the 2nd terminal point D2 is is roughly the same thus, and observes from peripheral part A, and the protuberance of the encapsulant of the protuberance of the encapsulant of the 1st terminal point D1 and the 2nd terminal point D2 becomes respectively from the diminishing shape of cleaning frame support body side direction photosensitive drums side.
Figure 12 is the figure that the flow process that the encapsulant ejection and the position of encapsulant blowoff are controlled is shown.
Figure 12 shows the process flow diagram of program performed in following so automatic sealer coater, and this automatic sealer coater has: encapsulant blowoff 300, and it begins and stops from nozzle 301 ejection encapsulants after receiving indication; The cleaning frame support body keeps platform, and it is with the predetermined attitude frame body 21 that keeps clean; And transfer arm, it is used to keep encapsulant blowoff 300, and moves sealing material blowoff 300 according to the D coordinates value of being imported.In addition; Situation as the three-dimensional coordinate position below having registered describes, that is: to remain on the cleaning frame support body keep the cleaning frame support body 21 on the platform the 1st starting point S1, the 1st terminal point D1, the 1st through a some T1, the 2nd through a some T2, the 2nd starting point S2, the 3rd through a some T3, the 2nd terminal point D2 and the 4th through some T4 separately, with respect to the relative three-dimensional coordinate position in the original position (home position) of these nozzle 301 front ends; And the relative three-dimensional coordinate position between each point.
In step S11 shown in Figure 12, accept the signal that the sealing coating work begins, make the never illustrated original position of front end of the nozzle 301 of encapsulant blowoff 300 move to the 1st starting point S1.In step S12, wait for that the front end of nozzle 301 arrives the 1st starting point S1, the ejection of encapsulant blowoff 300 indicating sealing materials is begun, and the front end of indication nozzle 301 moves to the 1st terminal point D1 from the 1st starting point S1.In step S13, indication stops the ejection of encapsulant 20 at once after the front end of nozzle 301 arrives the 1st terminal point D1.Like this, after just arriving the 1st terminal point D1, stop the ejection of encapsulant 20, thus, indicated stop to spray encapsulant 20 after, encapsulant 20 still can spray from nozzle, so seal member swells at the 1st terminal point D1.In step S14, the front end that makes the nozzle 301 after arriving the 1st terminal point D1 moves to the 1st process point T1 from the 1st terminal point D1 after, it is moved to the 2nd starting point S2 through a T2 through the 2nd from the 1st through some T1.In step S15, wait for that the front end of nozzle 301 arrives the 2nd starting point S2, indicating sealing material blowoff 300 begins to spray encapsulant, and the front end of indication nozzle 301 moves to the 2nd terminal point D2 through some T3 from the 2nd starting point S2 through the 3rd.In step S16, indication stops the ejection of encapsulant 20 at once after the front end of nozzle 301 arrives the 2nd terminal point D2.In step S17, the front end that arrives the nozzle 301 behind the 2nd terminal point D2 is moved through a some T4 from the 2nd terminal point D2 to the 4th.
