Description

Technical Field

[0001] The invention relates to the technical field of valve core production devices, and in particular to an automated valve core cutting and detection device. Background Art

[0002] There are various types of balls available on the market, including leather balls used in sports, such as basketballs, volleyballs, and soccer balls, as well as small inflatable balls for children to play with. Inflatable balls generally consist of a sphere and a valve core attached to the sphere via heat. To inflate the sphere, an air needle is inserted into the valve core through the front end of the air pump's air supply tube, filling the sphere with air. When the needle is removed, the valve core isolates the air inside and outside the sphere, giving the sphere a certain degree of elasticity.

[0003] Valve core Figure 16 As shown in the figure, during processing, a blind hole is first drilled in the core, and then a knife-edge-shaped air intake hole is cut into the blind hole. In existing technology, air intake holes are usually cut one by one using a small cutting device. After processing, inspectors then check each cut hole for quality. This traditional processing method is time-consuming and labor-intensive, significantly reducing production efficiency and labor costs. Summary of the Invention

[0052] The specific working process of the present invention is as follows:

[0053] S1. Loading: The operator pours a batch of valve cores 11 into the storage box 201, and the valve cores 11 fall into the vibrating plate loader 203 from the storage box 201. Under the action of vibration and gravity, the valve cores 11 are in the correct posture with the blind hole facing upward, and enter the loading channel 202 along the discharge port of the vibrating plate loader 203. The two loading belts 205 in the loading channel 202 clamp the valve cores 11 and transfer the valve cores 11 to the bottom of the front suction nozzle 304; when the number of valve cores 11 reaches twenty, the blocking rod 210 extends to block the valve core 11 at the rear, and at the same time the first clamping plate 208 fixes the valve core 11 to prevent it from shaking left and right.

[0054] S2. Posture detection: the front exhaust nozzle sucks up twenty valve cores 11 at a time and sends them to the second clamping plate 404. The second clamping plate 404 clamps the valve core 11 and rotates 180° so that all the blind holes of the valve core 11 face downwards; the posture detection probe 406 moves upwards, and the upper row of posture detection probes 406 extends into the blind hole. If there is a valve core 11 with a blind hole facing upwards, it means that the posture of the valve core 11 is wrong. At this time, the end face of the valve core 11 will squeeze the upper row of posture detection probes 406 so that it contacts and energizes with the lower row of posture detection probes 406; after the detection is completed, the second clamping plate 404 rotates 180°, and the rear row suction nozzle 309 sucks up the valve core 11 after posture detection, and places the valve core 11 with the wrong posture in the return material collection box 407. The operator regularly pours the valve core 11 in the return material collection box 407 back into the storage box 201.

[0055] S3. Cutting of air intake holes: The rear suction nozzle 309 places the valve core 11 on the third clamping plate 602. The third clamping plate 602 clamps the valve core 11. The tool 609 moves downward and extends into the blind hole to cut a through air intake hole in the blind hole. The waste falls into the waste collection box 610. The operator cleans the waste regularly.

[0056] S4. Pore detection: The upper row of pore detection probes 701 are moved to above the third clamping plate 602 and then inserted into the air inlet. The upper row of pore detection probes 701 move the valve core 11 to above the pressing sleeve 704 and move downward. If the blind holes are concentric and the air inlet is through, the upper exhaust hole detection probe 701 does not contact the lower exhaust hole detection probe 701. If the blind hole is eccentric or the air inlet is not through, the upper exhaust hole detection probe 701 contacts the lower exhaust hole detection probe 701, which indicates that the valve core 11 is defective.

[0057] S5. Separation of good and defective products: The upper exhaust hole detection probe 701 moves the valve core 11 to the top of the collecting hopper 1001, the upper dividing plate 802 extends to, and the stripping plate extends to push the valve core 11 into the leakage hole 805.
