Description

Technical Field

[0001] The utility model relates to the field of gas meter diaphragm production, in particular to a gas meter diaphragm laminating, taking and releasing material moving mechanism. Background Art

[0002] The diaphragm gas meter is a metering device used to measure gas usage. The working principle of the diaphragm gas meter is mainly based on the volumetric method, that is, cumulative metering is performed by measuring the gas volume flow rate. Its working process is as follows: When the gas enters the gas meter, a pressure difference will be generated at both ends of the gas meter inlet and outlet. This pressure difference pushes the diaphragm to reciprocate in the metering chamber, and at the same time drives the gas distribution mechanism to coordinate gas distribution. Each reciprocating movement of the diaphragm will discharge a certain amount of gas. When the roller rotates through a counting unit, a roller rotation metering display is realized, thereby realizing the cumulative metering of gas. In addition, the driving force of the diaphragm movement depends on the gas pressure difference at the inlet and outlet of the gas meter. When the diaphragm moves to the extreme position on one side, another diaphragm is required to generate the same driving force to drive the first diaphragm back to achieve continuous automatic metering.

[0003] Therefore, the diaphragm in the diaphragm gas meter is a very important component, and its manufacturing process includes the cutting of the diaphragm strip and the vulcanization of the diaphragm. After the diaphragm strip is cut to form a diaphragm, it needs to be transferred to the vulcanization equipment for vulcanization, and taken out from the vulcanization equipment after the vulcanization is completed. Because the diaphragm is thin and soft, it is transferred to the vulcanization equipment after cutting. The conventional multi-point adsorption fixed movement method will make the surface of the diaphragm uneven, thereby generating certain waves. When placed in the vulcanization equipment, the fall of the diaphragm will also generate certain waves when it falls into the vulcanization equipment due to the impression of the waves. This will cause the diaphragm to deform to a certain extent or fold in a small area in the vulcanization mold, resulting in a decrease in the overall thickness uniformity of the vulcanized diaphragm, which reduces the measurement accuracy of the diaphragm.

[0046] The present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0047] Embodiment:

[0048] As Figures 1 to 6 shown, a gas meter diaphragm fitting and picking / placement moving mechanism includes:

[0049] A planar moving mechanism 1, any planar two-dimensional moving structure can be used, such as a double-layer lead screw control mechanism or a cylinder mechanism, etc.;

[0050] A lifting mechanism 2, vertically arranged on the moving end of the planar moving mechanism 1;

[0051] A fixed frame 3, horizontally arranged and connected to the telescopic end of the lifting mechanism 2;

[0052] The central adsorption mechanism is arranged on the lower surface of the fixed frame 3 and is directly below the lifting mechanism 2; the adsorption width of the central adsorption mechanism is not less than the width of the diaphragm.

[0053] The synchronous separation and aggregation mechanism is arranged on the fixed frame 3.

[0054] Two side adsorption mechanisms are respectively arranged on the two movable ends of the synchronous separation and aggregation mechanism and are respectively located on both sides of the central adsorption mechanism; the adsorption width of the side adsorption mechanism is not less than the width of the diaphragm; the farthest distance between the two side adsorption mechanisms on the synchronous separation and aggregation mechanism is greater than the length of the diaphragm.

[0055] A negative pressure generator (not shown in the figure, and a vacuum pump can be used as the negative pressure generation source) is connected to the central adsorption mechanism and the two side adsorption mechanisms to provide negative pressure adsorption force.

[0056] The horizontal position is transferred through the planar movement mechanism 1, and the lifting and placement of the diaphragm are achieved through the lifting mechanism 2. The central adsorption mechanism is used to adsorb and fix the center of the diaphragm, and then the synchronous separation and aggregation mechanism is used to control the side adsorption mechanisms to stretch and adsorb and fix the diaphragm from both sides of the central adsorption mechanism to the two ends of the diaphragm. During this process, the diaphragm is stretched and fixed, so that the surface of the diaphragm is always in a tension state, and thus the diaphragm will not show waves caused by uneven stress.

[0057] In this embodiment, the central adsorption mechanism includes:

[0058] The main adsorption box 41 is in the shape of a closed box and is connected to the negative pressure generator; a plurality of through holes (not shown in the figure) are uniformly arranged on the lower surface of the main adsorption box 41; the outer side surfaces and the outer bottom surface of the main adsorption box 41 facing the two side adsorption mechanisms are rounded.

[0059] Bar-shaped air inlet holes 412 are provided on two opposite end faces of the main adsorption box 41.

[0060] The lower ends of the bar-shaped air inlet holes 412 are parallel to the inner bottom surface of the main adsorption box 41; main air inlet holes 413 are also provided on two opposite end faces of the main adsorption box 41.

[0061] The through holes are formed into suction holes to adsorb and fix the diaphragm. When the negative pressure is too high, an air path channel is formed through the bar-shaped air inlet holes 412 to generate negative pressure (the pressure on the side where the surface flowing gas is located is lower) to strengthen the adsorption of the diaphragm. At the same time, the negative pressure value is adjusted through the main air inlet holes 413 to prevent the diaphragm from denting into the through holes and causing damage to the surface of the diaphragm.

[0062] In this embodiment, a clamping chute 31 extending along the length direction of the fixed frame 3 is provided on the fixed frame 3.

[0063] The synchronous separation and aggregation mechanism includes:

[0064] Two carriages 51, which are slidably connected to the clamping chute 31; the edge adsorption mechanism is connected to the carriage 51;

[0065] Two fixing blocks 52, which are arranged on the fixing frame 3 and are provided with internal thread perforations parallel to the length direction of the fixing clamp;

[0066] A servo motor 53, which is arranged on the fixing frame 3;

[0067] Two lead screws 54 with opposite thread directions are respectively connected to both ends of the servo and pass through the corresponding fixing blocks 52 and are rotatably connected to the fixing frame 3.

[0068] By the rotation of the servo motor 53, the relative movement of the two carriages 51 is controlled.

[0069] In this embodiment, the edge adsorption mechanism includes a suction and pulling assembly; the suction and pulling assembly includes:

[0070] A secondary adsorption box 61, which is in a closed box shape and is communicated with a negative pressure generator; the secondary adsorption box 61 is arranged on the lower surface of the carriage 51; a plurality of adsorption holes are evenly arranged on the lower surface of the secondary adsorption box 61;

[0071] Two adsorption rollers 62 are respectively arranged on opposite sides of the secondary adsorption box 61, and the adsorption rollers 62 are perpendicular to the moving direction of the carriage 51; the lower surface of the adsorption rollers 62 is flush with the lower surface of the central adsorption mechanism.

[0072] The function of the secondary adsorption box 61 is the same as that of the main adsorption box 41. At the same time, since the secondary adsorption box 61 will move with the carriage 51, the adsorption rollers 62 are provided to prevent the secondary adsorption box 61 from scraping and moving with the diaphragm, but rolling to protect the surface of the diaphragm.

[0073] In this embodiment, the edge adsorption mechanism further includes a shaping mechanism; the shaping mechanism includes:

[0074] A shaping motor 63, which is arranged on the carriage 51 and is located between the secondary adsorption box 61 and the central adsorption mechanism;

[0075] Two universal joints 64 are respectively connected to both ends of the shaping motor 63;

[0076] Two shaping rollers 65 are rotatably arranged on the carriage 51 and are connected to the universal joints 64; the included angle between the axes of the two shaping rollers 65 is an obtuse angle and points to the adjacent secondary adsorption box 61; the lower surface of the shaping rollers 65 is not lower than the lower surface of the adsorption rollers 62.

[0077] If the diaphragm is already uneven before being taken, at this time, by the rotation of the shaping rollers 65 (the rotation direction is opposite to the moving direction of the carriage 51), the diaphragm is flattened and stretched during the unfolding process of the diaphragm.

[0078] In this embodiment, the edge adsorption mechanism includes two suction components; the two suction components are located on both sides of the shaping mechanism.

[0079] For the two suction components, the outermost one can adsorb and lift the diaphragm, and the inner one can fix the diaphragm shaped by the shaping mechanism.

[0080] In this embodiment, the shaping roller 65 is connected to the carriage 51 through a shaping spring 66; in the natural state, the horizontal height of the lower surface of the shaping roller 65 is lower than the horizontal height of the lower surface of the adsorption roller 62.

[0081] The shaping spring 66 can increase the extrusion force between the shaping roller 65 and the diaphragm, so as to better flatten the waves on the diaphragm.

[0082] In this embodiment, the telescopic end of the lifting mechanism 2 is connected to the fixed frame 3 through a pressing spring 21.

[0083] The pressing spring 21 can ensure that after a period of use, the main adsorption box 41 and the secondary adsorption box 61 can still have a good adsorption effect on the diaphragm.

[0084] The following is how the diaphragm fitting, picking, placing and moving mechanism of this embodiment is used. Control the planar moving mechanism 1 to be directly above the diaphragm to be picked up, control the servo motor 53 to rotate, so that the two carriages 51 approach the central adsorption mechanism; then control the lifting mechanism 2 to extend until the main adsorption box 41 descends to fit the diaphragm, and finally start the negative pressure generator.

[0085] Under the action of the negative pressure generator, the middle part of the diaphragm is adsorbed and fixed by the main adsorption box 41, and the diaphragms on both sides of the main adsorption box 41 are respectively adsorbed by the two edge adsorption mechanisms.

[0086] Then start the servo motor 53 to rotate, so that the two carriages 51 move relatively away from each other. At the same time, start the shaping motor 63 to rotate. The rotation direction of the shaping motor 63 is opposite to the movement direction of its corresponding carriage 51, that is, the shaping roller 65 pulls the diaphragm towards the end face of the diaphragm.

[0087] Under the action of the edge adsorption mechanism, the diaphragm begins to be adsorbed from the middle and pulled and flattened towards both ends. Until the adsorption box inside the edge adsorption mechanism adsorbs and fixes the end face of the diaphragm, the flattening and adsorption fixation of the diaphragm are completed.

[0088] Control the lifting mechanism 2 to shorten to lift the diaphragm, then control the planar moving mechanism 1 to move the diaphragm until the diaphragm is directly above the vulcanization mold. Then control the lifting mechanism 2 to extend so that the diaphragm fits inside the vulcanization mold. Finally, control the negative pressure generator to close, and the diaphragm is separated from the main adsorption box 41 and the secondary adsorption box 61.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the present technical solution, and they should all be covered within the scope of the claims of the present invention.
