Description

Technical Field

[0001] The utility model relates to CO alarm production equipment, in particular to a CO alarm iron sheet feeding device. Background Art

[0002] Carbon monoxide (CO) is a colorless, tasteless, and odorless gas that is very difficult to detect. Therefore, to detect CO concentration, an electrochemical CO alarm is required to detect the concentration and generate an alarm. This alarm requires the installation of a circular iron plate. Patent document CN206200490U discloses an automatic loading device that can load such iron sheets. It includes a vibration loading assembly, a loading robot assembly and a pressing robot assembly. The vibration loading assembly includes a vibration plate, a feed channel, a linear vibrator, a pushing cylinder and a pushing rod. The pushing cylinder drives the pushing rod to move along the feeding direction perpendicular to the feed channel. The loading robot assembly includes a horizontal feeding assembly, a vertical feeding cylinder and a clamping assembly. The horizontal feeding assembly includes a horizontal guide rail, a horizontal feeding cylinder and a horizontal feeding slide. The clamping assembly includes a clamping cylinder and a clamping claw installed on the clamping cylinder. The clamping cylinder drives the clamping claw to perform clamping movement. The pressing robot assembly is installed on a second mounting frame. The pressing robot assembly includes a pressing head and a linear robot. The linear robot drives the pressing head to perform lifting and clamping movements. Usually, this type of round iron sheet is loaded by using an ordinary vibration plate, direct vibration distribution, clamping cylinders, horizontal transfer to the top of the workpiece, and vertical cylinder lifting to press the iron sheet into the workpiece. However, this loading method, on the one hand, is prone to produce iron filings and dust due to the mutual friction between the vibrating iron sheets of the vibration plate, which will affect the detection accuracy of the alarm and make it difficult to meet the increasingly high cleanliness requirements of the CO alarm lifting components. On the other hand, due to the structural limitations of ordinary vibration plate loading, the layout requirements of the equipment are more rigid, and it is difficult to flexibly set the relative positions of the various mechanism components. At the same time. There is a lack of a secondary positioning mechanism, and the coaxiality of the iron sheet placed on the product is not high, which affects the quality of the product. Therefore, it is necessary to optimize the structure of this loading device to overcome the above-mentioned defects. Utility Model Content
