[0002] At present, the seal items sold by seal companies mainly include official seals, general seals, electronic seals, seals with embedded chips, and consumables for seals such as printing ink and stamp pads. Each link in seal making requires manual operation. In the original typesetting software, manual operations are required for the content of the seal surface, the arrangement, height, and size of the characters. Moreover, in the production process, there are work links such as manually extracting consumables, clamping the seal shell, and operating the engraving machine. After production, manual imprinting for record filing is required. These processes not only waste a large amount of labor but also have a high probability of errors. Crucially, as a proof of a unit's external activities, the official seal has a risk of forgery, imitation, or even making multiple copies of one official seal in the existing production process. Especially in the current trend of marketization of official seal production, it is very difficult for most seal-making companies to ensure the safety and controllability of the production process.

The spring part includes a jig guide rod 5 and a jig spring 8. The jig spring is sleeved on the jig guide rod. The jig guide rod is used to drive the ink-return stamp to move up and down under the operation of the pneumatic equipment. The above-mentioned "completely the same, partially the same, or completely different" specifically refers to: the seals include official seals, financial special seals, legal person seals, contract seals, and invoice seals, or other types of general-purpose seals. According to different seal-engraving requirements, corresponding jigs are set. The purpose of this embodiment is to introduce the composition of the ink-return stamp clamping mechanism. For the specifications of jigs for different seals, reference can be made to the attached drawings and adjusted in actual production. The self-service seal-making machine can engrave the clamped seal skin 28.

[0026] Further, the jigs are arranged side by side in pairs on a jig bottom plate 1, and the bottom of the positioning sleeve is installed on the jig bottom plate through a jig body 29.

[0027] Further, the bottom of the jig bottom plate is connected with jig cylinder brackets 22 that match the number of jigs. A jig cylinder is arranged in each jig cylinder bracket, and a plurality of jig guide rods are arranged around each jig cylinder bracket.

[0028] Further, upper washers 20 and lower washers 18 for limiting are respectively arranged at the ends of the jig guide rods.

[0029] Further, a friction part for facilitating clamping is arranged on the ink-return stamp body, and specifically, it can be made of rubber material.

[0031] Further, both ends of the fixture base plate are respectively connected to the first fixture rotating bracket 42 and the second fixture rotating bracket 56. A fixture slip ring flange 43 and a fixture slip ring sleeve 46 are provided at the connection between the first fixture rotating bracket 42 and the fixture base plate. A slip ring bracket 51 is provided between the fixture base plate and the first fixture rotating bracket 42.

The principle of the pneumatic-electric integrated conductive slip ring is a new type of special sliding linkage mechanism. It combines pneumatic elements, electric components, and the principle of precision mechanical sealing in the design, realizing an integrated technology. The basic principle of the pneumatic-electric integrated conductive slip ring is that on the slider at the end of the slip ring rod fixed at one end, a relay of the electric component is installed. When the slip ring rod rotates to a certain angle, the electric component contacts the slider, and the relay is turned on, thereby controlling the pneumatic element and achieving the function of controlling this linkage device.

[0037] The principle of the pneumatic-electric integrated conductive slip ring uses pneumatic components to achieve precision mechanical sealing, which can effectively reduce impurity factors during its movement, improve the rotation accuracy, and optimize the structure of the power transmission slip ring rod. It can also use a limited amount of gas to control precise actions, thereby saving resources, improving the environment, avoiding problems such as deformation and wear of the slider, extending its service life, and improving its reliability.

[0038] The principle of the pneumatic-electric integrated conductive slip ring has good durability. It can ensure continuous operation for a long time without correction and without consuming any transitional energy during the process, thus avoiding frequent maintenance and replacement. It can also shorten the response time and cooperate with other control systems to more effectively achieve high-precision control.
