[0028] Example 1

[0029] Refer to the attached Figure 1-3The small steel ball detection mechanism of this embodiment includes three parts: a silo loading unit 100, a detection unit 200, and a nail blowing loading unit 300. The silo loading unit 100 is used to place the steel balls to be detected and provide them to the detection unit 200. The detection unit 200 detects the diameter of the steel balls delivered by the silo loading unit 100, and delivers the detected steel balls to the nail blowing loading unit 300. The nail blowing loading unit 300 delivers the steel balls with qualified diameters to subsequent processes based on the results of the steel ball diameter detection by the detection unit 200, and discharges the steel balls that fail the detection and collects them without subsequent processing.

[0030] The silo loading unit 100 comprises a box-shaped silo 110 , and the box-shaped silo 110 is used to place steel balls to be tested.

[0031] A proximity sensor 120 is provided at the bottom of the silo 110 , and the proximity sensor 120 is used to detect whether there are steel balls that need to be detected in the silo. When the proximity sensor 120 detects that there are steel balls in the silo 110 , a signal is sent to the circular cylinder 130 .

[0032] A circular cylinder 130 is arranged at the front side of the silo 110 near the material box discharge port assembly 150, and the circular cylinder 130 receives the signal from the proximity sensor 120 and controls the telescopic state. The circular cylinder 130 contracts and drives the material box discharge port assembly 150 to open the material box discharge port, so that the steel balls to be detected in the silo 110 pass through the discharge port and arrive at the detection position of the detection unit 200 through the conveying pipe. After the steel balls are conveyed, the circular cylinder 130 extends and drives the material box discharge port assembly 150 to close the material box discharge port.

[0033] A slide rail 140 is provided at the lower portion of the silo 110 , and the slide rail 140 is used to adjust the height of the silo 110 so that the height of the discharge port of the silo 110 matches the feed port of the conveying pipeline.

[0034] The detection unit 200 includes a displacement cylinder 210, which is provided with a cylinder connecting assembly 211. The cylinder connecting assembly 211 is located at the end of a steel ball conveying pipeline. When the steel ball to be detected follows the conveying pipeline to the detection position on the cylinder connecting assembly 211, a through-beam optical fiber sensor 220 is provided at the detection position on the cylinder connecting assembly 211 to detect whether there is a steel ball at the detection position. When the through-beam optical fiber sensor 220 detects the steel ball at the detection position, a signal is generated and sent to the displacement cylinder 210. The displacement cylinder 210 is provided with a contact displacement sensor 230. When the displacement cylinder 210 receives the signal from the through-beam optical fiber sensor 220, the displacement cylinder 210 drives the contact displacement sensor 230 to approach the steel ball to measure the diameter of the steel ball at the detection position. The contact displacement sensor 230 sends two different signals to the nail blowing feeding unit 300 according to the measurement results.

[0035] The nail blowing feeding unit 300 includes a transfer cylinder 310 and a dividing cylinder 330. When the transfer cylinder 310 receives a signal from the contact displacement sensor 230 indicating that the diameter of the steel ball is qualified, the transfer cylinder 310 extends to push the cylinder connecting component 211 to move. A blowing port 320 is arranged above the cylinder connecting component 211. When the transfer cylinder 310 pushes the steel ball on the cylinder connecting component 211 to the blowing port 320, the blowing port 320 blows out steel balls that meet the requirements, facilitating the operation of subsequent processes. When the dividing cylinder 330 receives a signal from the contact displacement sensor 230 indicating that the diameter of the steel ball is unqualified, the dividing cylinder 330 retracts to cause the unqualified steel balls to fall out and not enter into subsequent operation.

[0036] During operation, the steel ball to be detected is placed in the silo 110, and the proximity sensor 120 senses the presence of the steel ball in the silo 110 and sends a signal. The circular cylinder 130 receives the signal, and the circular cylinder 130 changes from an extended state to a retracted state, driving the material box discharge port assembly 150 to open the discharge port. The steel ball to be detected follows the conveying pipeline from the discharge port to the detection position on the cylinder connecting assembly 211. When the steel ball to be detected falls to the detection position, the optical fiber sensor 220 detects the presence of the steel ball to be detected here and sends a signal. The displacement cylinder 210 receives the signal, and the displacement cylinder 210 extends to drive the contact The contact displacement sensor 230 touches the steel ball at the detection position to detect the diameter of the steel ball to be detected. If the detection meets the requirements, the contact displacement sensor 230 sends a signal to the transfer cylinder 310, and the transfer cylinder 310 extends to drive the cylinder connecting component 211 to move to the blowing port 320, so that the cylinder connecting component 211 is aligned with the discharge port at the detection position to facilitate the discharge of the steel ball. If the detected steel ball diameter does not meet the requirements, the contact displacement sensor 230 sends a signal to the material distribution cylinder 330 to retract, so that the steel balls that do not meet the requirements fall and are discharged.

[0037] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
