The A glue extractor 112 includes an extraction pump 1121, a pull rod 1122, a barrel 1123 and a tray 1124 which are connected in sequence. In specific operation, the A lifting driver 111 drives the A glue pump 112 to lift, thereby driving the material tray 1124 in the A glue pump 112 to lift and lower, so as to press the material tray 1124 into the A glue storage barrel, so that the material tray 1124 passes the Class A liquid silicone into the barrel 1123 through the material hole in the middle of the material tray 1124; at this time, the output end of the pump 1121 drives the pull rod 1122 to move up and down, so that the pull rod 1122 moves up and down in the barrel 1123, which can drive the Class A liquid silicone in the barrel 1123 to move to the first conveying pipe connected to the barrel 1123, and enter the first connection port 5111 of the feeding controller 500 through the first conveying pipe. It should be emphasized that the structure of the A glue pump module 110 has been widely used in the market, and is not limited to the above structure, and can be other conveying structures that can realize the conveying of liquid silicone.

[0066] In order to achieve quantitative delivery of Class A liquid silicone, a liquid level sensor is provided on the pumping pump 1121. The liquid level sensor is used to detect the amount of Class A liquid silicone in the A rubber storage cylinder.

[0067] In order to increase the delivery speed of the pumping pump 1121, the pumping pump 1121 can be designed as a plurality of pressure pump bodies connected in series.

[0068] It should be noted that, currently, when the liquid silicone in each of the A and B storage cylinders is used up, it is necessary to replace the new A and B storage cylinders to ensure continuous production, but the time for replacing the storage cylinders is relatively long, which affects the production efficiency and the continuity of production. Based on this, in order to improve the production efficiency and ensure the continuity of production.

[0069] Furthermore, there are multiple A glue storage cylinders and multiple B glue storage cylinders, multiple A glue storage cylinders are connected to multiple first connection ports 5111 through multiple first delivery pipes, multiple B glue storage cylinders are connected to multiple second connection ports 5112 through multiple second delivery pipes, multiple first delivery pipes are installed one-to-one in multiple A glue extraction modules 110, multiple second delivery pipes are installed one-to-one in multiple B glue extraction modules 120, multiple first connection ports 5111 are interconnected, and multiple second connection ports 5112 are interconnected. Through the above configuration, each first connection port 5111 is connected to the third connection port 5121, and each second connection port 5112 is connected to the fourth connection port 5122.

When in use, the feeding valves of the third connection port 5121, the fourth connection port 5122, the first connection port 5111 and the second connection port 5112 are opened simultaneously to ensure that the type A liquid silicone and the type B liquid silicone are simultaneously fed into the injection unit 200. In a specific setting, the number of the A rubber storage cylinder and the B rubber storage cylinder can be 2, 3, 4 or more.

More specifically, the robot arm 330 includes a molding drive component 331 that is communicatively connected to the control unit and a clamp 332 that is connected to the output end of the molding drive component 331. The clamp 332 opens and closes and lifts and lowers under the drive of the molding drive component 331. When the clamp 332 opens and closes, the corresponding clamp 332 clamps and releases the molding mold. When the clamp 332 lifts and lowers, the corresponding clamp 332 connects the injection port of the molding mold to the discharge port 3123 and pulls the molding mold out from the discharge port 3123.

[0073] In order to further improve production efficiency, multiple rubber products can be molded at the same time. Specifically, the diverter rod 312 includes a connecting rod 3121 and two discharge rods 3122 respectively arranged at both ends of the connecting rod 3121. In the specific setting, the connecting rod 3121 is preferably in a U-shaped structure, and the feed port 3111 is opened on the connecting rod 3121. The two ends of each discharge rod 3122 are respectively facing two discharge ports 3123 opened on the diverter plate 311. In the specific setting, each discharge port 3123 has a corresponding molding mold. Through the above setting, four rubber products can be molded at one time, which improves the molding volume and molding efficiency. It should be noted that each molding mold is clamped and fixed by a mechanical arm 330, and the number of clamping arms is consistent with the number of discharge ports 3123.

[0074] In order to control the liquid silicone to flow from the discharge port 3123 into the molding mold at a preset time, a needle valve connected to the control unit is provided in each discharge port 3123, and the liquid silicone in the corresponding discharge port 3123 flows to the molding mold or stops flowing by controlling the opening and closing of the needle valve. In addition, in order to prevent the injection unit 200 from injecting too much force on the liquid silicone, which causes the liquid silicone to push open the needle valve, a pressure relief valve 340 is provided on the diverter plate 311.

[0075] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
