Abstract
The utility model discloses a kind of vacuum screen printing hole plugging machine, it is desirable to provide a kind of vacuum screen printing hole plugging machine safety protection structure.This utility model includes that frame props up stay tube (1), screen frame frame lifting shaft (2), and described frame is propped up stay tube (1) side and is provided with stop mechanism (3), the cylinder (4) suitable with described stop mechanism (3).This utility model is applied to the technical field of vacuum screen printing hole plugging machine.
Description
Technical field
This utility model relates to a kind of vacuum screen printing hole plugging machine, particularly to a kind of vacuum screen printing hole plugging machine safety protection structure.
Background technology
During producing pcb board, need pcb board is carried out consent, forming the entity of certain function at foramen primum cavity, present technology typically uses vacuum screen printing consent, it would be desirable to the pcb board of consent puts into vacuum chamber, after vacuum pump set evacuates air, carried out consent by the consent inking device of intracavity, the most accurately hole is filled up, utilize oil return scraper that excess ink is scraped back original position, then seal shifter by table top, take out pcb board.After pcb board consent completes; during row inspection is filled in web plate leakage; after screen frame frame is risen; the method now generally used is to utilize motor brake to be fixed screen frame frame; it is not provided with other safety guard; but owing to screen frame frame is heavier, can stop the supple of gas or steam the most unavoidably, have a power failure and maloperation during rising and be fixing, screen frame frame easily drops and causes personal injury.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, it is provided that a kind of simple in construction, sense sensitive, use safety vacuum screen printing hole plugging machine safety protection structure.
The technical scheme is that this utility model of this utility model includes that frame props up stay tube, screen frame frame lifting shaft, and described frame is propped up stay tube side and is provided with stop mechanism, the cylinder suitable with described stop mechanism.
Further, it is provided with lower stops below described screen frame frame lifting shaft.
Further, it is provided with lifting shaft contiguous block between described screen frame frame lifting shaft and described lower stops.
Further, described lifting shaft contiguous block is provided with control switch, and the described switch that controls is induction apparatus.
The beneficial effects of the utility model are: include that frame props up stay tube, screen frame frame lifting shaft owing to this utility model uses, described frame is propped up stay tube side and is provided with stop mechanism, the design of the cylinder suitable with described stop mechanism, relative to existing vacuum screen printing hole plugging machine, it is in operation and stops the supple of gas or steam, has a power failure and can guarantee that in the case of maloperation that screen frame frame does not drops, ensure that the personal safety of operator, so this use new structure is simple, it is sensitive to sense, use safety.

Detailed description of the invention
As shown in Figures 1 to 4, in the present embodiment, this utility model includes that frame props up stay tube 1, screen frame frame lifting shaft 2, and described frame is propped up stay tube 1 side and is provided with stop mechanism 3, the cylinder 4 suitable with described stop mechanism 3.
In this example, it is provided with lower stops 5 below described screen frame frame lifting shaft 2.
In this example, it is provided with lifting shaft contiguous block 6 between described screen frame frame lifting shaft 2 and described lower stops 5.
In this example, described lifting shaft contiguous block 6 is provided with control switch, and the described switch that controls is induction apparatus 7.
Principle: the internal vacuum chamber screen printer of described a kind of vacuum screen printing hole plugging machine safety protection structure prevents from stopping the supple of gas or steam, having a power failure and maloperation, screen frame frame falls the injury caused to equipment and the person.When screen frame frame rises to highest order, cylinder stretches out brake block, at abnormal operation: have a power failure, stop the supple of gas or steam, lift motor brake failure time, brake block, all without retraction, is constantly in home.Described a kind of vacuum screen printing hole plugging machine safety protection structure designs anti-low level and falls and anti-chain inversion structures; bottom is provided with lower stops; prevent guide pillar descending excessive; it is mounted with in lifting shaft contiguous block position to control switch simultaneously; when lifting shaft comes downwards to lower stops extreme position; control switch and send signal, lift motor stop motion immediately.
This utility model is applied to the technical field of vacuum screen printing hole plugging machine.
Although embodiment of the present utility model describes with practical solution, but it is not intended that the restriction to this utility model implication, for those skilled in the art, will be apparent from according to this specification combination to the amendment of its embodiment and with other schemes.
