Disclosure of Invention

The invention provides a buffer type air pressure sucking disc device for assembling an intelligent gas meter of the internet of things, which can be used for adsorbing a diaphragm in the intelligent gas meter of the internet of things and can realize diaphragm transfer for the assembling purpose.

The invention provides a buffer type air pressure sucker device for assembling an Internet of things intelligent gas meter, which solves the problems through the following technical key points: the buffer type air pressure sucker device for assembling the Internet of things intelligent gas meter comprises a vacuum sucker and a lifting mechanism for changing the position of the vacuum sucker in space, wherein the direction of a sucker port of the vacuum sucker is parallel to the movement direction of the vacuum sucker;

still include the elastic component, the elastic component sets up between vacuum chuck and elevating system, and when vacuum chuck's sucking disc mouth received the thrust from the diaphragm, the elastic component takes place elasticity in vacuum chuck's direction of motion and shortens, elasticity shortens and makes the interval between vacuum chuck and the elevating system reduce.

The diaphragm is an important component of the intelligent gas meter of the internet of things, and the existing diaphragm is generally in a groove-shaped structure with an annular sealing part and a concave middle part at the edge. In order to avoid the deformation of the film during storage and transportation and to increase the amount of the film stored in a unit space before the film is manufactured to the completion of the assembly of the film on the watch core, a film lamination storage mode is generally adopted: the notches on the diaphragms are upward, and the bottom sides of the two diaphragms which are attached randomly are embedded into the groove body of the diaphragm below. When the diaphragm of the above stacking storage mode is used for assembling the intelligent gas meter of the internet of things, because the diaphragm is softer, and the area and the thickness of the diaphragm are larger, the diaphragm is separated and the position of the diaphragm is transferred in a manual operation mode during the assembly of the existing diaphragm.

This scheme provides one kind can adopt and realize the technical scheme of diaphragm separation and transfer based on the atmospheric pressure adsorbs the principle, and this scheme is when specifically using, vacuum chuck connects negative pressure equipment, like this, can obtain the adsorption affinity that is used for adsorbing the diaphragm at vacuum chuck's sucking disc mouth. Considering the characteristic that the diaphragm is easy to deform, in order to enable the adsorbed diaphragm to be transferred to a subsequent assembly station to realize automatic assembly, the deformation of the diaphragm is required to be smaller when the adsorption is completed, and the deformation control needs to consider two aspects: on the one hand, the suction force generated by the vacuum chuck is large, and on the other hand, the extrusion force to the diaphragm when the vacuum chuck is in contact with the diaphragm is large.

In order to solve the second problem above, it can be provided that the feed movement of the vacuum cup towards the membrane is slow when approaching the membrane, the second way being to provide the vacuum cup with a soft texture. However, in the above solutions, the problem of the approach speed may cause an increase in the difficulty of controlling the lifting mechanism or a reduction in the efficiency of adsorbing the diaphragm, and in the solution of the texture, in combination with the above problem of the magnitude of the suction force, the difficulty of deformation of the vacuum chuck directly affects the reliability of the vacuum chuck for adsorbing the diaphragm, and a significant effect is that after the vacuum chuck adsorbs the diaphragm, the maximum transmission speed of the diaphragm transmission is realized by the movement of the vacuum chuck in the future.

In this scheme, through setting up to still including the elastic component, and when vacuum chuck received the thrust that comes from the diaphragm, the elastic component produced the deformation that makes the interval between vacuum chuck and the elevating system reduce under above thrust, and vacuum chuck is to elevating system relative motion promptly, like this, vacuum chuck's speed reduction when can realizing vacuum chuck contact diaphragm through the elastic component reaches to reduce because vacuum chuck's collision produced deformation on the diaphragm. Under the effect of above elastic component, to the flexible design of vacuum chuck, needn't consider the problem that sets up the vacuum chuck more soft and influence the absorption reliability that leads to promptly.

Simultaneously, the sucking disc mouth orientation that sets up to each vacuum chuck in this scheme is parallel with vacuum chuck's direction of motion, be promptly if the diaphragm stacks up under vacuum chuck, notch on the diaphragm is directly over towards, and vacuum chuck's sucking disc mouth is just to the diaphragm, like this, under elevating system's effect, vacuum chuck makes reciprocal linear motion in vertical direction, thus, when vacuum chuck is the absorption feed motion towards the diaphragm, vacuum chuck is the normal pressure along the range upon range of direction of diaphragm to the effort of diaphragm, the event above feed motion process can not lead to causing diaphragm itself excessive deformation because the dislocation between the diaphragm, the absorption that causes because the deformation further warp or the adsorption position dislocation, it can effectively be shifted to the thing networking assembly station in order to realize intelligent automatic assembly to reach absorbent diaphragm.

To sum up, this atmospheric pressure sucking disc device not only can be arranged in the absorption of thing networking intelligent gas table diaphragm, simultaneously through setting up the elastic component can be so that the diaphragm produces littleer deformation in the adsorbed in-process with adsorbed back, realizes using the assembly to shift as the purpose diaphragm, realizes the application of intelligent manufacturing on thing networking intelligent gas table, is realizing the in-process of above purpose simultaneously, can not influence the absorption and the transmission efficiency to the diaphragm.

Meanwhile, the specific connection mode of the vacuum chuck and the connecting plate can effectively match the relative position precision of the vacuum chuck during installation, so that the vacuum chuck can form effective cooperative fit at the later stage; meanwhile, if the form of the membrane is changed, the scheme can also provide an adjusting way for the relative position of the vacuum chuck to adapt to the specific form of the membrane. Meanwhile, the specific connection form facilitates the linear adjustment of the position of the vacuum chuck relative to the connecting plate.

In order to avoid the deformation of the film during storage and transportation and to increase the amount of the film stored in a unit space before the film is manufactured to the completion of the assembly of the film on the watch core, a film lamination storage mode is generally adopted: the notches on the diaphragms are upward, and the bottom sides of the two diaphragms which are attached randomly are embedded into the groove body of the diaphragm below. When the diaphragm of the above stacking storage mode is used for assembling the intelligent gas meter of the internet of things, because the diaphragm is softer, and the area and the thickness of the diaphragm are larger, the diaphragm is separated and the position of the diaphragm is transferred in a manual operation mode during the assembly of the existing diaphragm.
