Abstract
The utility model discloses a suction confirming system of a vacuum suction cup, which is characterized by comprising a piston cylinder body as well as a piston and a spring that are arranged inside the piston cylinder body, wherein a closed containing cavity is formed by the piston and the piston cylinder body; the piston is arranged on the spring; and the other end surface of the piston is sealed and fixed with an approach switch movably contacted with the piston. The suction confirming system has simple structure, low manufacturing and maintaining cost, reliable work and high sensitivity, leads the system to make rapid response, and perfectly realizes automation and intellectualization of the production.
Description
Technical field
The utility model vacuum cup technical field, system is confirmed in the sorption that relates to a kind of vacuum cup more specifically.
Background technology
Now, the sorption of following vacuum cup confirms that system is the extensively understanding of people institute on market, the sorption affirmation system of this vacuum cup has two kinds of common form: a kind of is the detection mode that adopts contact, and promptly the Direct observation sucker has or not sorption to judge to workpiece.Another kind is to use the vacuum tightness pressure transducer to detect the vacuum state of vacuum chamber, and judges that with this vacuum cup has or not the sorption workpiece.
The sorption of this two kinds of vacuum cups confirms that the existing shortcoming of system is: first kind of detection mode is can only work as when sucker leaves the sorption position to judge just whether sucker touches object, rely on the people to detect fully and need to judge whether interrupt system, thereby vacuum cup is carried out necessary adjustment.Though second kind of detection mode can realize detecting automatically and can auto stop, the alarm maintenance, its acquisition cost is too high, has increased the input amount of fund, does not calculate.
Summary of the invention
The purpose of this utility model is exactly provide for the deficiency that solves prior art a kind of not only simple in structure, and manufacturing and maintenance cost are low, and reliable operation, highly sensitive, and system is confirmed in the sorption that can make system make the rapid-action vacuum cup.
The utility model is to adopt following technical solution to realize above-mentioned purpose: system is confirmed in a kind of sorption of vacuum cup, it is characterized in that, it comprises the piston and the spring of piston/cylinder and interior setting thereof, piston and piston/cylinder form an airtight cavity volume, piston is placed on the spring, the other end sealing and fixing of piston have with its movable contact near switch.
As further specifying of such scheme, the end of described piston/cylinder is provided with packed-piston cylinder body and fixing cylinder cap near switch.
The built-in cavity of described cylinder cap is arranged in this cavity near the end of switch, and the both sides of this cavity are respectively arranged with through hole.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The utility model adopts the piston be furnished with spring and matches near switch, when fan blower vacuumizes vacuum chamber, if the complete sorption workpiece of vacuum cup and occur to leak vacuum phenomenon, then after vacuum tightness reaches setting value, negative pressure will appear in the airtight cavity volume at spring place, under the promotion of atmospheric pressure to piston, piston will compression spring towards away from the direction motion that detects active zone near switch, just can not produce approach signal near switch, so system will know that the vacuum condition of vacuum chamber is good, thereby can conclude vacuum cup sorption workpiece fully; It is simple in structure, and manufacturing and maintenance cost are low, and reliable operation, highly sensitive can make system make rapid reaction, ideally makes to produce to realize robotization and intellectuality.

Description of reference numerals: 1, piston/cylinder 2, spring 3, piston 4, cylinder cap 5, near switch
Embodiment
As shown in Figure 1, system is confirmed in the sorption of a kind of vacuum cup of the utility model, comprises a piston/cylinder 1, is used to place piston 3 and spring 2; A cylinder cap 4 is used for packed-piston cylinder body and fixing near switch; A piston 3 is used for forming an airtight cavity volume with piston/cylinder; A spring 2 is used for piston is produced a reset force; One near switch 5, is used to detect piston and has or not to come in contact or reach it with its end face and trigger distance.Its version is: spring 2 is inserted earlier in the piston/cylinder 1, and then piston 3 is placed on the spring 2, screws on cylinder cap 4 also being installed on the other end of cylinder cap near switch 5, at last whole detection device is installed on the vacuum chamber.
In the use, when fan blower vacuumizes vacuum chamber, if the complete sorption workpiece of vacuum cup and occur to leak vacuum phenomenon, then after vacuum tightness reaches setting value, negative pressure will appear in the airtight cavity volume at spring place, under the promotion of atmospheric pressure to piston, piston will compression spring towards away from the direction motion that detects active zone near switch, just can not produce approach signal near switch, so system will know that the vacuum condition of vacuum chamber is good, thereby can conclude vacuum cup sorption workpiece fully.If but vacuum cup does not have complete sorption workpiece and vacuum phenomenon occurs leaking; then vacuum chamber just can't reach the vacuum tightness that makes the Piston Compression spring required; piston will be near the detection zone that also arrives near switch near switch under the thrust of spring; make near switch and produce approach signal; system will judge vacuum cup immediately after received signal do not have complete sorption workpiece and make vacuum chamber occur leak vacuum, and at this moment system will hard stop and sends the maintenance alarm.
