In this case, the key cap is likely to be damaged by increasing the feeding distance when pressed. Therefore, the suction pipe is set to be rigid, and the feeding distance of the key cap is also made easier to calculate and set. The stability of the key cap mounting action is increased.

The adsorption mechanism is arranged on the triaxial module, and the triaxial module controls the movement of the adsorption mechanism. The triaxial module controls the movement of the adsorption mechanism, wherein the movement in the vertical direction is used for sucking the key cap and installing the key cap, and the movement in the horizontal direction is used for adjusting the position of the adsorption mechanism, so that the relative positions of the adsorption mechanism and the face cover can be corresponding.

Detailed Description

The technical scheme of the utility model is clearly and completely described by a specific implementation mode of the embodiment of the utility model with the aid of the attached drawings.

Referring to fig. 1, the utility model discloses a device for installing key caps of a gas meter, which comprises a vibrating plate 7 for ordering key caps and a suction mechanism for sucking the key caps, wherein the key caps in the vibrating plate 7 are ordered and output from the vibrating plate 7 under the action of vibration and finally output to the suction range of the suction mechanism, so that the suction mechanism can suck the key caps.

When the conveying device conveys the surface cover of the gas meter to the installation position, the positioning mechanism arranged on the conveying belt carries out jacking positioning on the surface cover, and the suction mechanism can install the key cap at the appointed position of the surface cover. After the face cover is installed and the key cap is finished, the face cover is replaced by the positioning structure to the conveying device, and the face cover is conveyed to a downstream process for processing by the conveying device.

The output end of the vibration disk 7 is provided with a conveying groove 6, and the conveying groove 6 is used for conveying the key caps to the suction range of the suction mechanism. Under the vibration action of the vibration disc 7, the key cap entering the conveying groove 6 at the back pushes the key cap entering the conveying groove 6 to move forwards, so that the key cap can continuously move along the conveying groove 6 and finally move to the position of the suction mechanism.

The end of the conveying groove 6 close to the suction mechanism is a tail end, the tail end of the conveying groove 6 is closed, and when the key cap reaches the tail end of the conveying groove 6, the key cap cannot move continuously. The button cap cannot move at the tail end of the conveying groove 6, so that the suction mechanism can suck the button cap in a fine-fitting manner.

The width of the tail end of the conveying groove 6 is equal to the width of the key caps, so that the key caps at the tail end of the conveying groove 6 are arranged in a row, and the adsorption mechanism 1 is convenient for sucking the key caps at the tail end of the conveying groove 6.

The suction mechanism is arranged on a triaxial module 3, and the movement of the suction mechanism is realized through the triaxial module 3.

In one embodiment, the adsorption mechanism 1 realizes the adsorption of the key cap by a vacuum adsorption mode. The vacuum adsorption mechanism 1 is provided with a vacuum adsorption hole, and the vacuum adsorption hole is connected with negative pressure equipment such as a vacuum pump, so that negative pressure can be formed in the vacuum adsorption hole. When the vacuum adsorption hole contacts the key cap, the key cap is adsorbed by the adsorption structure under the negative pressure. The key cap then moves following the movement of the suction mechanism 1.

In one embodiment, the adsorption mechanism 1 is provided with an adsorption tube, the vacuum adsorption hole is a pipeline of the adsorption tube, and the adsorption tube sucks the key cap. The purpose of the adsorption tube is to make the bottom of the adsorption mechanism 1 protrude, so that the position of the vacuum adsorption hole can be conveniently observed and judged. And set up the distance that the adsorption tube can also control vacuum adsorption structure body and conveyer trough 6, the size of adsorption tube is littleer, moves between conveying mechanism 8, location structure more easily.

The adsorption tube adopts a rigid hard tube, and when the adsorption mechanism 1 is used for installing the key cap on the surface cover, the key cap is required to be forced to be pressed on the surface cover by pressure. Therefore, the adoption of the hard tube can ensure that the absorption structure cannot generate buffer deformation when the key cap is pressed, so that the feeding amount of the triaxial module 3 is consistent with the moving distance of the key cap, and the key cap can be stably fixed on the face cover.

The pipeline structure is adopted to directly adsorb the key cap, so that the key cap is suitable for the characteristic of small volume of the key cap.

The suction mechanism 1 needs to further determine the position of the face cover fixed by the positioning mechanism through the vision mechanism 2 before the key cap is installed. The visual mechanism 2 is connected with the adsorption mechanism 1, and the visual mechanism 2 and the adsorption mechanism 1 synchronously move.

Before the safety check cap is installed, the vision mechanism 2 shoots the position of the face cover, and transmits the shot pattern to the controller controlling the triaxial module 3, and the controller compares the position of the face cover with the set position, so that the actual position of the face cover is determined, and the moving path of the triaxial module 3 is determined.

After the moving path is determined, the triaxial module 3 moves with the vision mechanism 2 and the suction mechanism 1, thereby mounting the key cap on the specified position of the face cover. The last action of the triaxial module 3 is always a downward pressing action by which the key cap is pressed onto the face cover.

The adsorption mechanism 1 is provided with the adsorption tube protruding towards the lower side, so that the blocking of the vision mechanism 2 can be reduced, and the vision mechanism 2 can shoot the face cover conveniently.

The positioning structure is used for positioning the face cover. The positioning structure comprises a lifting mechanism for lifting the cover off the conveying mechanism 8 and a clamping assembly for fixing the cover.

The jacking mechanism is provided with a jacking platform, the conveying mechanism 8 adopts a belt conveyor with double conveying belts, and the jacking platform is positioned between the two conveying belts, so that the surface cover can be jacked away from the conveying mechanism 8 from the middle part of the surface cover.

Similarly, the belt conveyor can also adopt four conveying belts or more conveying belts, and only the installation position of the middle jacking platform needs to be reserved.

In one embodiment, the lifting action of the lifting platform is lifted by a servo cylinder. The jacking distance can be controlled more accurately by adopting the servo electric cylinder, and the surface cover after jacking is determined to be positioned between the clamping assemblies.

The clamping assembly can clamp and fix the face cover from two sides. The clamping assembly is provided with a fixed clamping jaw and a movable clamping jaw, and when the jacking platform jacks the face cover between the fixed clamping jaw and the movable clamping jaw, the movable clamping jaw stretches to push the face cover to be abutted against the fixed clamping jaw, so that the face cover is fixed. The fixed clamping jaw is arranged to determine the position of the face cover after each fixing, and the positioning effect of the face cover is realized while the face cover is fixed. When the key cap is installed, the surface cover is supported from the lower side by the jacking platform and is fixed from the side by the clamping assembly, so that the effect that the position of the surface cover is unchanged when the key cap is installed is achieved, and the key cap is not subjected to buffer effect when pressed to the surface cover.

After the key cap is installed, the movable clamping jaw is shortened, and the jacking platform is lowered, so that the dough cover is put back into the conveying mechanism 8, and the dough cover is conveyed to the downstream through the conveying mechanism 8.

The extension and shortening of the movable clamping jaw can be realized through a servo electric cylinder or an air cylinder.

The movable clamping jaw and the fixed clamping jaw are both provided with notches for positioning the face cover, the side edges of the notches are provided with chamfers, and the positions of the face cover are guided through the chamfers. Even if there is a positional deviation of the cover in the conveying direction of the conveying mechanism 8, the position of the cover can be corrected by the guiding action of the chamfer in the clamping process, so that the position of the cover is more accurate.

The movements of the triaxial module 3, the jacking mechanism and the clamping assembly are controlled by a controller, and the controller can adopt an industrial computer.
