In addition, about the concrete shape of the above-mentioned otch 20 of unit installing component 18, for example the width of otch 20 and the degree of depth (the guiding degree of depth) can be set at, and when connecting in the inner end of screw shaft 36 and otch 20 rubber flap 31 are positioned just.
Action effect to above-mentioned silk-screen printing device describes below.
Above-mentioned silk-screen printing device before operation begins, is carried out, and glue squeegee unit 30 is installed in the preparation on the said units installing component 18 of head 1.This installation is finished by operating personnel, this moment, operating personnel only needed the otch 20 on each screw shaft 36 insertion unit installing components 18 of rubber flap unit 30, simultaneously rubber flap unit 30 is overlapped on the unit installing component 18, fastening then operation screw rod 37, rubber flap unit 30 is fixed on the unit installing component 18, so just can quickly and easily glue squeegee unit 30 be installed on the head 1.Substrate in addition is fixed in the reference position of regulation with the overlapping state that matte M arranged.
After preparation was finished, operating personnel imported the indication that operation begins, head 1 entry into service thus, and this silk-screen printing device begins to carry out presswork.
Particularly, at first, running by mobile unit 2, rubber flap 31 is set at the top of the operation starting position of regulation, and by the running of unit installing component 18, rubber flap unit 30 rotates displacement simultaneously, as shown in Figure 1, rubber flap 31 is shifted to when right-hand, and shown in the solid line among this figure, rubber flap 31 is set at the heeling condition to travel direction anteflexion (acute angle).At this moment, the angle of attack β (attack angle) of rubber flap 31 when presswork set.Angle of attack β is meant the contact angle of rubber flap 31 with respect to matte M, rubber flap 31 is contacted and when carrying out paste expansion operation, rubber flap 31 is with respect to the angle of inclination (referring to Fig. 6 (a)) of matte M with matte M.
Then, by the running (decline) of lifting unit 4, rubber flap 31 is set at the height and position of the contact point butt on marginal portion and the matte M.At this moment, drive control lifting unit 4 according to the detected value of pressure sensor 12, make rubber flap 31 with predefined pressure crimping on matte M.Above-mentioned rubber flap 31, after being set at the height and position that contacts with matte M, shown in Fig. 6 (a), the sliding contact surface 34a of one side of transverse leak-proof plate 34 and matte M butt, in this example, because transverse leak-proof plate 34 can rotate, so as long as in rule certain angle scope (this example is 40 °～70 ° a scope), angle of attack β can both make transverse leak-proof plate 34 have no suitably to contact with gap with respect to matte M when being arbitrarily angled.Particularly, for example during angle of attack β=70 °, the sliding contact surface angle [alpha] of above-mentioned transverse leak-proof plate 34 is 70 °, when therefore rubber flap 31 being contacted with matte M, shown in Fig. 6 (a), transverse leak-proof plate 34 is maintained at the neutral position and contacts with matte M by installed surface 32a.Relative therewith, when angle of attack β＜sliding contact surface angle α, for example under angle of attack β=60 °, 40 ° the situation, if rubber flap 31 is contacted with matte M, respectively shown in Fig. 6 (b), (c), the elastic force of transverse leak-proof plate 34 opposing plate-shaped springs sheet 38a and rotate displacement from the neutral position, and under this state, contact with matte M.And transverse leak-proof plate 34 under the effect corresponding to the elastic force of the degree of crook of plate-shaped springs sheet 38a, and is crimped on the matte M.
Thus, after rubber flap 31 is crimped on the contact point of regulation, supply with paste by not shown feedway to matte M, the running rubber flap 31 by mobile unit 2 can move along X-direction simultaneously, and the paste on the matte M moves (advancing) by this of rubber flap 31 and is expanded.At this moment, can positively prevent the laterally excessive of paste suppressing agent, so the expansion operation of paste can suitably be carried out by transverse leak-proof plate 34.
Behind the rubber flap 31 incoming terminal positions, the rising by lifting unit 4 and the upset of unit installing component 18 drive, and shown in two chain-dotted lines among Fig. 1, the incline direction of rubber flap 31 is switched, simultaneously transverse leak-proof plate 34 towards also being switched together.Subsequently, identical with above-mentioned steps, rubber flap 31 moves along X-direction after being set at the height and position that contacts with matte M, and the paste on the matte M moves (returning) by this of rubber flap 31 and is expanded.This moment transverse leak-proof plate 34 opposite side sliding contact surface 34a, promptly the sliding contact surface 34a of opposite side inequality is crimped on the matte M when advancing, thus transverse leak-proof plate 34 can stop the laterally excessive of paste when advancing in the same manner.
Then, rubber flap 31 towards being overturn, and rubber flap 31 moves back and forth along matte M, paste is expanded thus, can be with paste coating (printing) on substrate so go up formed peristome by matte M.
Behind the certain repeatedly number of times of above-mentioned reciprocal running, presswork finishes, and rubber flap 31 returns to the home position, and a series of pressworks of this silk-screen printing device are all over.
After presswork finished, as required, rubber flap unit 30 was replaced with and can keeps the rubber flap rubber flap unit that produces corresponding to afterwards corresponding to the rubber flap unit of production afterwards.This operation is also finished by operating personnel, at this moment, operating personnel only need unclamp the standing screw 40 of above-mentioned rubber flap unit 30, to remove the stationary state of rubber flap unit 30 and unit installing component 18, along otch 20 rubber flap unit 30 is taken off from unit installing component 18 then, so just can be quickly and easily unload glue squeegee unit 30 on 1 from the head.
As mentioned above, this silk-screen printing device, wherein the two ends of the length direction of rubber flap 31 are provided with transverse leak-proof plate 34, transverse leak-proof plate 34 can carry out relative displacement with respect to rubber flap 31, particularly be to rotate around standing screw 40 with respect to unit installing component 18, in the certain angle scope (in 40 °～70 ° the scope), when angle of attack β is arbitrarily angled, all can make transverse leak-proof plate 34 have no suitably to contact with matte M with gap, in case paste suppressing agent is laterally excessive.The free degree with respect to the angle of attack β (contact angle) of matte M that therefore can keep rubber flap 31 can prevent the waste that causes because of paste is excessive simultaneously preferably, and makes paste stick to the problem that matte M goes up the position of story coating to take place.
Particularly, in this device, the effect of transverse leak-proof plate 34 by plate-shaped springs sheet 38a can above-mentioned neutral position be shaken possibly for benchmark elasticity and is provided with, simultaneously when 70 ° of angle of attack β less thaies, as mentioned above, transverse leak-proof plate 34 can be resisted the elastic force of plate-shaped springs sheet 38a and begin to rotate displacement from the neutral position, and transverse leak-proof plate 34 is crimped on the matte M under the effect of post-equalization power (elastic force of above-mentioned biasing member 38), therefore transverse leak-proof plate 34 positively can be crimped on the matte M, in case paste suppressing agent is laterally excessive.
In addition, in this device, rubber flap 31 is maintained on the rubber flap fixator 32, this assembly (rubber flap unit 30) is freely installed with respect to 18 dismounting of unit installing component, and transverse leak-proof plate 34 is installed on the rubber flap fixator 32, therefore can carry out the replacing operation of rubber flap 31 and transverse leak-proof plate 34 quickly and easily.Promptly, the form of transverse leak-proof plate 34 and interval need to change according to the size and the angle of attack β of rubber flap 31 sometimes, adopt said structure, only need to be installed in advance on the rubber flap fixator 32 with rubber flap 31 with corresponding to the size of rubber flap 31 and the transverse leak-proof plate 34 of angle of attack β, when changing rubber flap 31, can change transverse leak-proof plate 34 simultaneously, therefore compare with the structure of transverse leak-proof plate 34 with dismantling rubber flap 31 respectively, the replacing operation of rubber flap 31 and transverse leak-proof plate 34 can be convenient and quick.
Especially in this device, otch 20 is set on unit installing component 18 on the one hand, the screw rod 36 that is bolted with operating nut 37 is set on rubber flap unit 30 on the other hand, only need when screw rod 36 is inserted otch 20, rubber flap unit 30 to be overlapped on the unit installing component 18, fastening then operating nut 37, rubber flap unit 30 can be fixedly mounted on the head 1, the opposite unclamp operation nut 37 that only needs, rubber flap unit 30 is separated with unit installing component 18, just can be from the head take off rubber flap unit 30 on 1, therefore adopt above-mentioned disassembly and assembly structure, can carry out the replacing operation of rubber flap unit 30 (rubber flap 31 and transverse leak-proof plate 34) quickly and easily.
But above-mentioned silk-screen printing device is an example of silk-screen printing device involved in the present invention, and its concrete structure only otherwise break away from aim of the present invention, can be done suitable change.
For example in above-mentioned example, transverse leak-proof plate 34 is shaken the structure that supports possibly by elasticity, be the elastic force that has utilized plate-shaped springs sheet 38a (biasing member 38), but also helical spring can be inserted on the standing screw 40, utilize the elastic force of this spring that transverse leak-proof plate 34 elasticity are shaken possibly and supported.So long as when angle of attack β＜sliding contact surface angle α, can produce elastic force, the structure that the sliding contact surface 34a of transverse leak-proof plate 34 is crimped on the matte all can be used.
In addition, except that above-mentioned biasing member 38 is set transverse leak-proof plate 34 elasticity are shaken the structure that is supported possibly, also can adopt transverse leak-proof plate 34 can rely on it to focus on the above neutral position of stating be the structure of shaking in the certain limit of benchmark, and transverse leak-proof plate 34 can be connected to structure on the matte M by its deadweight when rubber flap 31 is contacted with matte M.
In addition, be that transverse leak-proof plate 34 is installed in structure on the rubber flap fixator 32 (rubber flap unit 30) that is provided with possibly with respect to head 1 (unit installing component 18) dismounting in the above-mentioned example, transverse leak-proof plate 34 be directly installed on structure on the unit installing component 18 but also can use.But the form of transverse leak-proof plate 34 and interval need to change according to the size and the angle of attack β of rubber flap 31 sometimes, consider the operating characteristics when changing, to adopt the structure that transverse leak-proof plate 34 is installed on the rubber flap fixator 32 (rubber flap unit 30) in the above-mentioned example comparatively desirable.
