Description

Technical Field

[0001] The utility model relates to the technical field of embossing machines, in particular to a membrane switch embossing machine. Background Art

[0002] Membrane switch is a multi-layer structure (flat) type (non-locking) key switch, which integrates the functions of key, indicating element, instrument panel, etc. It consists of four parts: panel, upper circuit, isolation layer, and lower circuit. When the membrane switch is pressed, the contact of the upper circuit deforms downward and contacts with the plate of the lower circuit. When the finger is released, the contact of the upper circuit rebounds, the circuit is disconnected, and the loop triggers a signal.

[0003] The button embossing on the membrane switch is achieved by embossing the key area on the mask layer through an embossing machine. Therefore, the use of the embossing machine is crucial in the production process of the membrane switch. For example, the existing patent with publication number CN218782946U proposes a membrane switch embossing machine, which avoids the operator from taking materials under the upper press table by setting a material changing mechanism, thereby improving the operator's work safety. At the same time, the lower press table is moved out from the base, increasing the space for material changing, making it easier for the operator to place unprocessed membrane switches on the lower press table, thereby improving the efficiency of material changing for the membrane switch.

[0004] However, in the above technical solution, although the material changing efficiency of the user for the membrane switch can be improved by setting up a material changing device, when a large number of membrane switches need to be embossed, it is difficult for the device to automatically and continuously complete the loading operation, resulting in limited embossing efficiency of the membrane switches. Therefore, the utility model aims to provide an efficient embossing machine that can perform embossing operations on a large number of membrane switches. Utility Model Content

[0027] When the user performs the embossing operation on the switch body 2 by using the membrane switch embossing machine with the above structure, he first places several switch bodies 2 into the feeding part 3, and then uses the electric telescopic rod 4 to movably penetrate the feeding part 3 to push the switch body 2 in the feeding part 3 from the discharge port 5 to the lower pressing plate 6. The limit groove 9 on the lower pressing plate 6 will limit the shaking of the switch body 2. Then, the hydraulic cylinder 8 is used to drive the upper pressing plate 17 to press the switch body 2 on the lower pressing plate 6 to perform the embossing operation on the switch body 2. After the embossing operation is completed, the switch body 2 on the lower pressing plate 6 is removed, and the electric telescopic rod 4 is used again to push the switch body 2 in the feeding part 3 onto the lower pressing plate 6 in turn for embossing operation, thereby improving the embossing efficiency of the switch body 2.

[0028] In this embodiment, a plate changing groove 10 is provided on the operating table 1, and the lower pressure plate 6 is placed in the plate changing groove 10. A locking device 11 is provided between the operating table 1 and the lower pressure plate 6. The locking device 11 selectively fixes the lower pressure plate 6 and the operating table 1 relatively to limit or allow the lower pressure plate 6 to move along the length direction of the plate changing groove 10; when the user needs to replace the lower pressure plate 6, the locking device 11 is used to release the relative fixed state between the lower pressure plate 6 and the operating table 1, and then the lower pressure plate 6 is pulled away from the plate changing groove 10, and then, the replaced lower pressure plate 6 is placed in the plate changing groove 10, and then the locking device 11 is used to selectively fix the lower pressure plate 6 and the operating table 1 relatively to limit or allow the lower pressure plate 6 to move along the length direction of the plate changing groove 10, so as to facilitate the user to maintain and replace the lower pressure plate 6.

[0029] In this embodiment, the locking device 11 includes two locking plates 12 and a locking rod 13. The two locking plates 12 are relatively spaced apart and arranged on both sides of the plate changing slot 10 on the side of the operating table 1, and the locking rod 13 movably passes through the two locking rods 13; when the user needs to replace the lower pressure plate 6, the locking rod 13 is separated from the two locking plates 12, and then the lower pressure plate 6 is pulled away from the plate changing slot 10, and then the replaced lower pressure plate 6 is placed in the plate changing slot 10, and then the locking rod 13 is inserted between the two locking plates 12 to limit or allow the lower pressure plate 6 to move along the length direction of the plate changing slot 10, so as to facilitate the user to maintain and replace the lower pressure plate 6.
