Description

Technical Field

[0001] The invention relates to the field of jewelry processing, and in particular to a spring buckle detection device. Background Art

[0002] In the field of jewelry, spring clasps are a common jewelry accessory, often used in necklaces, bracelets and other accessories. The basic structure of spring clasps can be found in Figure 1 One section of the circular main ring has a notch, and an arc-shaped active buckle is sleeved inside the hollow inner cavity of the main body. The action of the active buckle is controlled by turning the switch on the side of the main body. When the active buckle retracts into the inside of the main body, the notch is exposed, and other accessories can be inserted into the inner ring of the main body. At this time, the active buckle compresses the spring; when the switch is released, the spring resets and pushes the active buckle to reclose the notch, so that the accessories are fixed in the inner ring of the main body, thereby completing the assembly connection of the jewelry, such as the connection between the chain part and the pendant part of the necklace.

[0003] In order to improve the quality stability of jewelry, defective spring buckles must be eliminated during production; when the important performance parameters of the spring buckle are unqualified, it will affect the assembly process of the jewelry or affect the wearing, such as whether the spring buckle is smooth to open, whether the automatic reset and closure can be completed smoothly, whether the dimensional parameters such as the inner diameter and the angle meet the requirements, etc. At present, the process of such spring buckle inspection is mainly completed manually by the production staff in the production workshop.

The interior of the main body 101 is a hollow structure, and a circular arc-shaped active buckle 104 and a spring are set inside the hollow inner cavity. The switch 103 can drive the active buckle 104 to move, so that the active buckle 104 moves in an arc trajectory. A notch is opened in one section of the main body 101. When the buckle is opened, the switch 103 is pushed to make the active buckle 104 retract into the main body 101, and the notch is exposed. At this time, the spring is in a compressed state; when the buckle is closed, the switch 103 is released, and the spring reset force will push the active buckle 104 to pop out and re-close the notch.

[0035] See also Figure 2-Figure 5The spring buckle detection device includes: a storage device 10, a turntable 20, a mechanical gripper, an action module, a test module and a control module.

The test column 70 is fixed at an eccentric position of the output shaft of the test servo motor 80, and the test servo motor 80 is fixedly connected to the output end of the test lifting module 90. Figure 7 A through slot 32 is formed on the fixture seat 30, and the through slot 32 is vertically penetrated, so that the test column 70 can extend into the slot from the bottom and move in a circular arc track horizontally upward. When the test column 70 rises straight into the through slot 32, the test column 70 is located on the side of the switch 103 of the spring buckle 1.

[0038] The test module is the software detection part of the test, including: the camera aperture 100, the control module with a preset software program and the display 110 connected by signals. The camera aperture 100 is set above the detection station 22, and performs full-process image acquisition during the test of the spring buckle 1; the preset software program will first store the standard image of the spring buckle 1, and the control module is used to compare and analyze the real-shot image sent back by the camera aperture 100 and the pre-stored standard image, and output the test results to the control module and the display 110 according to the difference in the comparison values. After receiving the comparison detection information, the display 110 shows the specific test data of the spring buckle 1 and the judgment result of whether the test is qualified. The control module is also connected to the test module and each mechanical gripper through a signal to control each mechanical gripper to perform a coordinated action according to the test results. It should be noted that the image recognition module used in the test module can be purchased from outside, and its specific implementation principle is not repeated in this article; of course, the standard image of the spring buckle 1 needs to be taken by the production personnel in advance, uploaded to the program of the image recognition module, and the various standard values ​​of the spring buckle 1 are pre-entered.

[0039] During operation: the loading clamp 40 takes out the spring buckle 1 workpiece to be tested from the storage device 10, and places it into the workpiece accommodating cavity 31 of the fixture seat 30 of the loading station 21.

At this time, the action module works, and the test lifting module 90 drives the test column 70 to move straight up, so that the test column 70 extends into the through groove 32 of the fixture seat 30. At this time, the test column 70 is tightly against the switch 103 on the side of the spring buckle 1; the test servo motor 80 then drives the test column 70 to move in a circular arc trajectory horizontally upward, so that the test column 70 pushes the switch 103 of the spring buckle 1, so that the spring buckle 1 repeatedly opens and closes. During the detection process, the camera aperture 100 collects images of the entire test process of the spring buckle 1, and transmits the real-shot images back to the preset software program. The real-shot images contain multiple numerical information of the spring buckle 1 in static and action (opening and closing buckle) states, such as the opening and closing degree of the active buckle 104, the inner diameter size of the spring buckle 1, the angle between the fixed buckle 102 and the switch 103, etc. After the system completes the test comparison of the two images, it outputs the qualified or unqualified judgment result to the control module. The turntable 20 continues to rotate, driving the spring buckle 1 to the defective product rejection station 23. If the judgment result is unqualified, the control module controls the defective product clamping claw 50 to clamp the spring buckle 1 out to remove the defective product; if the judgment result is qualified, the turntable 20 continues to rotate, does not stop at the defective product rejection station 23, and continues to drive the spring buckle 1 to the good product unloading station 24. The control module controls the good product clamping claw 60 to clamp the spring buckle 1 out to complete the good product unloading. This cycle is repeated over and over again, and each spring buckle 1 is continuously tested and classified.
