Background technology
Existing full-automatic plate glass screen process press, its main structure as shown in Figure 1, (glass printing industry publishing house publish be entitled as " serigraphy worker technology ", in March, 1994 is by Zheng Dehai, " specialty printing " that Zheng Junming and Shen Qing write and Chemical Industry Press publishes, in January, 2002 is by Wu Xue Zhi Zheng, Chen Na writes), mainly comprise frame 10, printing frame and printing frame elevating mechanism 11, from net hydraulic cylinder 12, half tone governor motion 13, slide automatic station-keeping system 14, printing table 15, wheel carrier lift and conveyer structure and auxiliary template elevating mechanism 16, operation control system 17; Wherein print frame and print frame elevating mechanism 11 and comprise the big arm 111 of lifting, can be along the reciprocating print head device 112 of the line slide rail that is installed in 111 sides, four jiaos big arm lifting guide pillars 113 are positioned on the frame 10 by mount pad 114, and can under the driving of reducing motor, make the 113 unified liftings of four jiaos big arm lifting guide pillars, thereby the different adjustable height requirements when making parts 11,12 and 13 realize printing, Hui Mo with the wiping version, reducing motor 115 tractions are band synchronously, print head device 112 is moved back and forth realize printing, returns black function; From net hydraulic cylinder 12 tops be connected from the net reducer output shaft, its power is provided by reducing motor 115, end on the liquid road about in the of 12 from the net hydraulic cylinder during printing, half tone 134 lifts and prints synchronously, hydraulic cylinder liquid road conducting about in the of 12 when returning China ink, the elongation of hydraulic cylinder 12 pull bars makes half tone 134 get back to the level position, keeps horizontal Hui Mo; Half tone governor motion 13 comprises that to version regulating handle 131,132 half tone 133 and net are apart from regulating handle 134, and half tone is lifted on the big arm 111 for four jiaos; Slide automatic station-keeping system 14 is clamped slide by air cylinder driven; Printing table 15 provides the air pump 152 of absorption affinity when comprising the working plate 151 that supports slide and the printing of slide location; Wheel carrier lift and conveyer structure and auxiliary template elevating mechanism 16 comprise wheel carrier 161 and lifting driving and the feed drive device of carrying slide, and auxiliary template 162 is used for preventing when full version is printed the climbing of print head 112.
At present, the domestic vehicle glass printing production line full-automatic screen printer that is used for needs and the pre-determined bit conveyer at its front end, needs and the supporting use of following sheet conveyer in its back-end; Glass carries out pre-determined bit before seal after, transfer on the workbench of printing machine, after transport tape descends, after the degradation action is finished under location and the auxiliary template once more, can print by band or roller.Glass need carry out twice the location before printing like this, and glass on work top, locate do not finish before other relevant actions can not carry out, so the production line production capacity is lower.
Summary of the invention
The purpose of this utility model is for overcoming the weak point of prior art, design a kind of three workshop section's sliding desk type full-automatic glass press structures, this structure is each printing process of operation step by step, be improved to respectively and finish simultaneously in three workshop sections, save the stand-by period of equipment when operating step by step, increased substantially production efficiency.
Three workshop section's sliding desk type full-automatic glass press structures of the utility model design, comprise frame, it is characterized in that, also comprise being installed in location active section, printing work section, the unloading piece active section that is connected mutually on this frame, be arranged on the transmission slide unit that described three active sections below makes these three active section continued operations.
Workflow of the present utility model is: slide is transferred to the location active section from the prime conveyer and positions, and by after the sucker on the accurate transmission slide unit absorption, accurately last slice transfer to the printing work section fast; After slide reached the printing work section fast, printing table rose slide absorption, finish printing work by printing mechanism after, general who has surrendered's slide goes to accurate transmission slide unit under the printing table, accurately transmits slide unit by the servomotor driven in synchronism, finishes sheet up and down simultaneously; When accurately the transmission slide unit moves to the unloading piece active section, reduce to low level, slide is placed on the transport tape, import printed glass into back level conveyer smoothly by transport tape; Accurately the transmission slide unit is finished and is dropped to low level after slide shifts, and the subsequent printings circulation is waited in inverted running and playback again.
Characteristics of the present utility model and effect
Adopt press structure of the present utility model, when under the control of operation control system, moving, three active sections can be finished different work simultaneously: when print zone was carried out presswork, positioning section can be finished operations such as material loading and location synchronously, and the unloading piece active section can be finished operations such as blanking transmission synchronously; When print zone is returned black operation, can finish synchronously that slide unit accurately transmits, printing table rises and operation such as printed document exchange; With each step action that common automatic screen-printing machine need be finished one by one, finish simultaneously in three workshop sections respectively, significantly enhance productivity.
The utility model is compared with common automatic screen-printing machine, its production capacity advantage is very obvious, equipment print with Hui Mo in, automatically finish, unloading piece transmission, the location, slide unit is preparation such as transmission accurately, saved the stand-by period of equipment when each substep moves, can significantly enhance productivity, according to the difference of printed dimensions, the maximum production capacity of this machine can reach 450~650pcs/h.

Three active sections of present embodiment and transmission slide unit all can select for use conventional products to assemble.
The technological process of each active section of the efficient full-automatic glass printing machine of three workshop section's sliding desk types of the present utility model is described in detail as follows respectively:
Locating active section:
After glass imports positioning section into by the prime conveyer, can be parked in position to be positioned automatically;
Then, the positioning supports beam rises, and glass is held up from transport tape;
Each positioning sleeve clamps slide and positions;
Glass after finish the location is sucked by the vacuum cup on the accurate transmission slide unit;
The positioning supports beam descends subsequently;
Accurately the transmission slide unit starts, finish synchronously back, location glass last slice and following of printing back glass.
In the printing work section:
When the China ink operation is reversed back by printing mechanism, accurately transmit slide unit slide is accurately transferred to the printing work section, printing table rises slide is held up and absorption;
It is high-order that printing table rises to printing;
Printing mechanism is just changeing prints;
Be completed for printing the back printing table and reduce to low level, slide is positioned on the accurate transmission slide unit;
Slide after accurately the transmission slide unit will print fast transfers to the unloading piece active section, and the slide that will descend a slice to have good positioning synchronously transfers to the printing work section.
At the unloading piece active section:
When the printing work section was returned the China ink operation, the slide that will accurately transmit after slide unit will print fast transferred to the unloading piece active section;
Accurately the transmission slide unit is reduced to low level, and the slide behind the seal is positioned on the unloading piece transport tape;
The startup of unloading piece transport tape spreads out of the unloading piece active section with slide;
Slip transmission frame counter-rotating playback performs next time the preparation of transmission fast.
