Abstract
The utility model discloses a semi-automatic screen printing machine safety control device based on photoelectric sensing. One end of a screen plate (2) is provided with a photoelectric emitter (7), the other end of the screen plate (2) is provided with a photoelectric emitting plate (8) matched with the photoelectric emitter (7), and the photoelectric emitter (7) and the photoelectric emitting plate (8) are arranged below the screen plate (2); a cross beam (1) is fixedly provided with a motor driver (9) which is electrically connected with the photoelectric emitter (7), and the motor driver (9) is further connected with a lifting drive motor (10). The semi-automatic screen printing machine safety control device can accurately sense whether an arm of an operator is under the screen plate through the photoelectric emitter and the photoelectric emitting plate, and stops pressing downward immediately if it is detected that the arm of the operator is under the screen plate, and therefore personal safety of the operator is protected.
Description
Technical field
The utility model relates to a kind of semi-automatic silk-screen machine safety control based on optoelectronic induction.
Background technology
The full name of screen printer is screen process press, be a kind of equipment of solder(ing) paste or Heraeus being bitten on PCB pad by silk screen, be mainly used in electronics processing industry, the silk-screen mark of printed circuit board, the mark of tool housing panel, the solder(ing) paste printing in circuit board process etc.Its operation principle is as follows: through transmission mechanism transferring power, allow sdueegee push at the volley ink and screen printing forme, make screen printing forme and stock form a nip, because silk screen has tension force N1 and N2, sdueegee is produced to power F2, screen resilience make screen printing forme except nip not with stock joint, ink by mesh, is bitten stock from moving nip under the extruding force F1 of sdueegee effect.
Semi-automatic silk-screen machine can improve printing and the production efficiency of pcb board to a great extent, and the parent who has been subject to vast pcb board production firm looks at.But existing semi-automatic silk-screen machine does not arrange the function of security control conventionally, so-called security control refers in the time that operator operates screen printer, avoids screen printing forme to press down the arm that is pressed onto operator in process, infringement operator's personal safety.At present, also having part screen printer is to support security control, but its security control all adopts sensing contact form to realize, only after screen printing forme is pressed onto operator's arm, could responds to and control motor and stop declining, still there is certain danger in operator's work.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, the semi-automatic silk-screen machine safety control based on optoelectronic induction that can effective guarantee operator personal safety.
The purpose of this utility model is achieved through the following technical solutions: the semi-automatic silk-screen machine safety control based on optoelectronic induction, semi-automatic silk-screen machine comprises crossbeam, screen printing forme, sdueegee and operating desk, stock is placed in position corresponding with screen printing forme on operating desk, sdueegee is installed on crossbeam by horizontal slip mechanism, crossbeam and screen printing forme are slidably mounted on respectively on upright guide rail, one end of described screen printing forme is provided with photoemitter, the other end is provided with the photoelectric reflection plate matching with photoemitter, photoemitter and photoelectric reflection plate are all arranged at the below of screen printing forme, on crossbeam, be installed with motor driver, motor driver is electrically connected with photoemitter, and motor driver is also connected with lifting drive motors.
Described motor driver comprises reference level modular converter and comparator, the output of photoemitter is connected with the in-phase input end of comparator, the inverting input of comparator is connected with reference level modular converter, and the output of comparator is connected with lifting drive motors.
The beneficial effects of the utility model are: photoemitter and photoelectric reflection plate are set below screen printing forme; by photoemitter utilizing emitted light signal after baffle reflection is returned by transmitter receipt; if photoemitter does not receive the optical signal reflecting; the arm that is judged as operator has blocked the propagation of light in centre; thereby stop pressing action by lifting drive motors control screen printing forme; reach the object of protection operator personal safety, have simple in structure, cost is low, recognition accuracy high.

Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1, semi-automatic silk-screen machine safety control based on optoelectronic induction, semi-automatic silk-screen machine comprises crossbeam 1, screen printing forme 2, sdueegee 3 and operating desk 4, stock 5 is placed in position corresponding with screen printing forme 2 on operating desk 4, sdueegee 3 is installed on crossbeam 1 by horizontal slip mechanism, crossbeam 1 and screen printing forme 2 are slidably mounted on respectively on upright guide rail 6, one end of described screen printing forme 2 is provided with photoemitter 7, the other end is provided with the photoelectric reflection plate 8 matching with photoemitter 7, photoemitter 7 and photoelectric reflection plate 8 are all arranged at the below of screen printing forme 2, on crossbeam 1, be installed with motor driver 9, motor driver 9 is electrically connected with photoemitter 7, and motor driver 9 is also connected with lifting drive motors 10.
As shown in Figure 2, motor driver 9 comprises reference level modular converter and comparator, the output of photoemitter 7 is connected with the in-phase input end of comparator, and the inverting input of comparator is connected with reference level modular converter, and the output of comparator is connected with lifting drive motors 10.The conversion of reference level modular converter obtains reference level, then it is compared with the signal (signal that photoemitter 7 is exported) of in-phase input end, and comparator is output as high level or low level, and then realizes the control to lifting drive motors 10.
The above is only preferred embodiment of the present utility model, be to be understood that the utility model is not limited to disclosed form herein, should not regard the eliminating to other embodiment as, and can be used for various other combinations, amendment and environment, and can, in contemplated scope described herein, change by technology or the knowledge of above-mentioned instruction or association area.And the change that those skilled in the art carry out and variation do not depart from spirit and scope of the present utility model, all should be in the protection domain of the utility model claims.
