[0037] In this embodiment, the preferred embodiment is as follows: Figure 3 and Figure 6 As shown, a material arrival sensor is provided on the side of the enclosure 304 facing the feed inlet. The material arrival sensor is used to detect whether the material carrier 6 has been conveyed into place on the feeding platform 303.

[0038] Specifically, the material arrival sensor can be an infrared distance sensor. When the material carrier 6 is conveyed to the loading platform 303 by the loading conveyor belt 305, the infrared distance sensor will monitor the conveying position of the material carrier 6. After the material carrier 6 is completely conveyed to the loading platform 303, the infrared distance sensor will upload a signal to the control system. The control system will control the loading conveyor belt 305 to stop conveying and drive the loading electric push rod 302 to start, which will drive the material carrier 6 to rise above the loading port 104 and enter the placement slot of the conveyor seat 103. Then it can move and be conveyed with the conveyor seat 103.

[0039] In this preferred embodiment, the pre-pressing positioning component includes a pre-pressing seat 204, which is vertically slidably connected to the upper stamping die 203 and is provided with an elastic element between it and the upper stamping die 203.

[0040] Specifically, when the valve piece blank is punched and formed, the hydraulic cylinder 201 drives the upper punch die 203 to descend, and after descending, the pre-pressing seat first contacts the conveying seat 103, and the positioning guide columns 205 extend into the positioning holes 108 respectively to position and fix the conveying seat 103, and finally the pre-pressing seat 204 is pressed on the conveying seat 103 and the material loading seat 6 to achieve final complete fixing, and then the upper punch die 203 is punched and descended to punch and form the valve piece blank on the material loading seat 6.

[0041] Preferably in this embodiment, as shown in Figure 1 and Figure 4 The annular conveying path is provided with a waste material discharge port 106 directly below the upper punch die 203, and a waste material collecting box 7 is arranged below the waste material discharge port 106, which is used to collect the waste material generated in the punching process. The material loading seat 6 is provided with a punching opening, so that the material loading seat 6 is both a punching die and a positioning carrier. The waste material generated after punching falls into the waste material discharge port 106 and then into the waste material collecting box 7 below.

[0042] Preferably in this embodiment, the visual detection mechanism 4 includes a visual fixing frame 301 and a visual camera. The visual fixing frame 301 is fixed to the annular frame 101, and the visual camera is installed on the visual fixing frame 301 and faces the conveying seat 103 on the annular conveying belt 102. A fill-in light is arranged on one side of the visual fixing frame 301.

[0043] Specifically, after the valve piece blank is punched and formed and conveyed to the visual camera, the visual camera performs visual detection on the valve piece blank after punching to check whether the valve piece blank is a good product. During visual detection, the fill-in light irradiates the valve piece blank below the visual camera to avoid the influence of poor light on detection.

[0044] Preferably in this embodiment, as shown in Figure 5 The conveying seat 103 is provided with a positioning block 109 on the top side, and the punching mechanism 2 and the visual detection mechanism 4 are both provided with a positioning sensor 8 capable of cooperating with the positioning block 109. The positioning sensor 8 is used to detect the in-place condition of the conveying seat 103.

[0045] Specifically, the positioning sensor 8 can be a travel switch. When the conveying seat 103 is conveyed to the punching mechanism 2 or the visual detection mechanism 4, the positioning block 109 contacts the travel switch to trigger, the travel switch receives a signal and transmits it to the control system, and the control system controls the annular conveying belt 102 to stop the conveying seat 103 at the punching mechanism 2 or the visual detection mechanism 4, and then performs the punching process or the visual detection process.

[0046] Preferably in this embodiment, as shown in Figure 1As shown, the discharging mechanism 5 includes a discharging chute and a discharging conveyor belt, the discharging chute is vertically arranged, and the top opening of the discharging chute is opposite to the discharging port 105, and the discharging conveyor belt is below the discharging chute, and the starting end of the discharging conveyor belt is opposite to the bottom opening of the discharging chute.

[0047] In this embodiment, preferably, as Figure 4 As shown, a plurality of guide sliding balls 107 are arranged on the annular conveying track, so that when the carrier seat 6 is located in the conveying seat 103, the bottom of the carrier seat 6 can be in contact with the plurality of guide sliding balls 107, reducing the friction of the bottom of the carrier seat 6 on the conveying track of the annular conveying belt 102, and making the conveying of the carrier seat 6 more smooth.

[0048] Working process and principle:

[0049] The workers put a plurality of valve plate blanks on the carrier seats 6 in advance, then put the carrier seats 6 into the carrier frames 307 of the loading carrier 306 and stack them, then push the loading carrier 306 to the conveying starting end of the loading conveyor belt 305, then pull out the pull plate 309, so that the carrier seats 6 are automatically dropped onto the loading conveyor belt 305 under the action of gravity, then the loading conveyor belt 305 conveys the carrier seats 6 to the conveying end, and when the carrier seats 6 below the carrier frame 307 are conveyed away by the loading conveyor belt 305, the carrier seats 6 above will continue to be discharged, so that the carrier seats 6 will automatically fall onto the loading conveyor belt 305;

[0050] When the carrier seats 6 are conveyed to the loading platform 303 by the loading conveyor belt 305, and the carrier seats 6 are completely in place, the arrival sensor will upload a signal to the control system, the control system controls the loading conveyor belt 305 to stop conveying, and drives the loading electric push rod 302 to start, drives the carrier seats 6 to rise above the loading port 104 and enter the placing groove of the conveying seat 103;

[0051] Then the annular conveying belt 102 drives the conveying seat 103 and the carrier seat 6 to start conveying on the annular conveying track, when the conveying seat 103 passes through the stamping mechanism 2, the positioning sensor 8 at the stamping mechanism 2 detects that the conveying seat 103 is in place, then the positioning sensor 8 uploads a signal to the control system, the control system controls the annular conveying belt 102 to stop conveying, and drives the hydraulic cylinder 201 of the stamping mechanism 2 to start pressing, and starts the stamping process;

[0052] When the stamping is completed, the annular conveying belt 102 continues to drive the finished valve plate product after stamping to be conveyed, when the valve plate product is conveyed to the visual detection mechanism 4 along with the annular conveying belt 102, the positioning sensor 8 at the visual detection mechanism 4 detects the in-place condition of the conveying seat 103 and the material loading seat 6, and uploads to the control system, and the control system controls the visual camera to visually detect the valve plate product on the material loading seat 6;

[0053] After the visual detection is completed, the annular conveying belt 102 continues to convey the material loading seat 6, when the material loading seat 6 is conveyed to the discharging port 105, the material loading seat 6 automatically falls from the discharging port 105 and slides along the discharging chute to the discharging conveying belt, and then is automatically conveyed to the end by the discharging conveying belt, and is manually collected or subjected to other processes by other equipment.

[0054] In the present application, by setting the positions of the feeding port 104, the discharging port 105, the stamping mechanism 2 and the visual detection mechanism 4 on the annular conveying belt 102 and the spacing positions of the plurality of conveying seats 103 on the annular conveying belt 102, the feeding port 104, the discharging port 105, the stamping mechanism 2 and the visual detection mechanism 4 are stopped with one material loading seat 6 each time the annular conveying belt 102 is stopped, so that the feeding, discharging, stamping and visual detection processes of the material loading seat 6 can be simultaneously performed when the annular conveying belt 102 is stopped.

[0055] The present application sets the annular conveying mechanism 1, the stamping mechanism 2, the visual detection mechanism 4, the feeding mechanism 3 and the discharging mechanism 5, so that the feeding, conveying, stamping, visual detection and discharging of the valve plate blank can be automatically completed, without manual operation, with high intelligence and high stamping forming efficiency.

[0056] The above is only the preferred embodiment of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments, and any technical solution falling within the concept of the present application is within the protection scope of the present application. It should be noted that, for ordinary skilled persons in the art, some improvements and refinements without departing from the principle of the present application are also considered to be within the protection scope of the present application.
