The to-be-detected valve nozzles 205 are placed on the upper surface of the conveyor belt 204. The upper surface of the support plate 206 abuts against the inner side of the conveyor belt 204.

[0031] In the embodiment of the present utility model, the operator places the workbench 1 on a designated place for detecting valve nozzles through the support legs 101 to ensure stability. Then, the collection box 102 is placed on one side of the workbench 1 for collecting the detected valve nozzles. The collection box 102 is divided into a qualified area 103 and an unqualified area 104. The qualified area 103 is located directly below the conveyor belt 204 for storing the detected qualified valve nozzles, and the unqualified area 104 is used for storing the detected unqualified valve nozzles. During detection, the to-be-detected valve nozzles 205 are evenly arranged on the conveyor belt 204. The motor 202 drives the conveying roller 203 to rotate, and the rotation drives the conveyor belt 204 to move for conveying the to-be-detected valve nozzles 205. The conveyor belt 204 is supported by the support plate 206 to ensure its stable operation.

[0032] In some embodiments, as Figures 1 - 5 shown, as a preferred embodiment of the present utility model, a detection assembly 3 is provided on the upper surface of the workbench 1.

[0033] In the embodiment of the present utility model, the detection assembly 3 includes a fixed frame 301 fixedly connected to the upper surface of the workbench 1. A cylinder 302 is fixedly connected to the top of the inner cavity of the fixed frame 301. A moving plate 303 is fixedly connected to the lower end of the cylinder 302. An upper pressure sensor 304 is fixedly connected to the lower surface of the moving plate 303. Two triangular push rods 305 are symmetrically and fixedly connected to the lower surface of the moving plate 303. A plurality of telescopic rods 306 are symmetrically and fixedly connected to both sides of the inner cavity of the fixed frame 301. One end of the telescopic rod 306 is fixedly connected to an arc-shaped clamping rod 307. A side pressure sensor 308 is fixedly connected to the inner cavity of the arc-shaped clamping rod 307. A triangular push block 309 is fixedly connected to the outer surface of the arc-shaped clamping rod 307. A spring 310 is sleeved on the outer surface of the telescopic rod 306. One end of the spring 310 is fixedly connected to the fixed frame 301, and the other end of the spring 310 is fixedly connected to the arc-shaped clamping rod 307. A controller 311 is fixedly connected to the upper surface of the fixed frame 301.

[0034] In the embodiment of the present utility model, the starting cylinder 302 drives the moving plate 303 and the upper pressure sensor 304 to move downward to squeeze the valve nozzle 205 to be detected, and the pressure value received by the valve nozzle 205 to be detected is detected. When the moving plate 303 moves downward, it drives the triangular push rod 305 to move downward, thereby squeezing and pushing the triangular push block 309 and the arc-shaped clamping rod 307 inward, driving the arc-shaped clamping rod 307 to perform a linear movement inward in cooperation with the telescopic rod 306, squeezing both sides of the valve nozzle 205 to be detected, and detecting the pressure value received by the valve nozzle 205 to be detected through the side pressure sensor 308. The arc-shaped clamping rod 307 can be used to fix the position of the valve nozzle to ensure its stability during the detection process.

[0035] And the elastic force of the spring 310 drives the arc-shaped clamping rod 307 to automatically reset, realizing the automation of clamping and releasing, reducing the need for manual intervention. The upper pressure sensor 304 and the side pressure sensor 308 will transmit the detected pressure values to the controller 311. The controller 311 compares the detected data with the preset data to determine whether the valve nozzle is qualified. By using the upper pressure sensor 304 and the side pressure sensor 308 in combination, the pressure distribution at different positions of the valve nozzle 205 to be detected can be more comprehensively understood, thereby improving the accuracy of the detection result and detecting whether the compressive capacity of the valve nozzle meets the standard.

[0036] In some embodiments, as Figures 1 - 3 shown, as a preferred embodiment of the present utility model, a blanking assembly 4 is provided on the lower surface of the workbench 1.

[0037] In the embodiment of the present utility model, the blanking assembly 4 includes a fixing plate 401 fixedly connected to the lower surface of the workbench 1. One side of the fixing plate 401 is fixedly connected with an electric push rod 402. One end of the electric push rod 402 is fixedly connected with an inclined blanking plate 403. The controller 311 is electrically connected to the upper pressure sensor 304, the side pressure sensor 308, and the electric push rod 402 through wires. The inclined blanking plate 403 is located above the qualified area 103 of the collection box 102, and the inclined blanking plate 403 is arranged at an angle of 45°.

[0038] In the embodiment of the present utility model, when the valve nozzle 205 to be detected is qualified, it is automatically conveyed outward through the conveyor belt 204 and falls into the qualified area 103 of the collection box 102 for unified collection. When the detected data deviates from the preset data and is unqualified, the controller 311 controls the electric push rod 402 to push the inclined blanking plate 403 outward and position it above the qualified area 103 of the collection box 102. At this time, the unqualified valve nozzle 205 to be detected falls on the inclined blanking plate 403, and through its inclined design, it helps the valve nozzle 205 to be detected to slide into the unqualified area 104 of the collection box 102 for unified collection. The electric push rod 402 pushes the detected valve nozzle to the corresponding collection area according to the instruction of the controller 311. After the valve nozzle is pushed to the designated area, the electric push rod 402 returns to the initial position, waiting for the detection and blanking of the next valve nozzle. Each valve nozzle can be quickly and accurately classified, ensuring quality control on the production line and improving the efficiency of detection and classification.

[0039] Working principle: During the use of the device, the operator arranges the valve nozzles 205 to be detected evenly on the conveyor belt 204. The conveyor roller 203 is driven to rotate by the motor 202, and the conveyor belt 204 is driven to move by rotation to convey the valve nozzles 205 to be detected. The conveyor belt 204 is supported by the support plate 206 to ensure its stable operation.

[0040] The valve nozzle 205 to be detected is conveyed by the conveyor belt 204 to directly below the upper pressure sensor 304. Then, the air cylinder 302 is started to drive the moving plate 303 and the upper pressure sensor 304 to move downward to squeeze the valve nozzle 205 to be detected, and the pressure value received by the valve nozzle 205 to be detected is detected. When the moving plate 303 moves downward, it drives the triangular push rod 305 to move downward, thereby squeezing and pushing the triangular push block 309 and the arc-shaped clamping rod 307 inward, driving the arc-shaped clamping rod 307 to move linearly inward in cooperation with the telescopic rod 306, squeezing both sides of the valve nozzle 205 to be detected, and detecting the pressure value received by the valve nozzle 205 to be detected through the side pressure sensor 308. The arc-shaped clamping rod 307 can be used to fix the position of the valve nozzle to ensure its stability during the detection process, and the arc-shaped clamping rod 307 is automatically reset by the elastic force of the spring 310 itself.

[0041] The upper pressure sensor 304 and the side pressure sensor 308 will transmit the detected pressure values to the controller 311. The controller 311 compares the detected data with the preset data to determine whether the valve nozzle is qualified. By using the upper pressure sensor 304 and the side pressure sensor 308 in combination, the pressure distribution at different positions of the valve nozzle 205 to be detected can be more comprehensively understood, thereby improving the accuracy of the detection result and detecting whether the compressive capacity of the valve nozzle meets the standard. When the valve nozzle 205 to be detected is qualified, it is automatically conveyed outward through the conveyor belt 204 and falls into the qualified area 103 of the collection box 102 for unified collection. When there is a deviation between the detected data and the preset data and the detection is unqualified, at this time, the controller 311 controls the electric push rod 402 to push the inclined blanking plate 403 to move outward and be located above the qualified area 103 of the collection box 102. At this time, the unqualified valve nozzle 205 to be detected falls on the inclined blanking plate 403. Through its inclined design, it helps the valve nozzle 205 to be detected to slide into the unqualified area 104 of the collection box 102 for unified collection. The electric push rod 402 pushes the valve nozzle that has completed the detection to the corresponding collection area according to the instruction of the controller 311.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the present invention in each embodiment.
