Embodiment Construction
[0021] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.
[0022] refer to figure 1 , figure 2 , image 3 A metal chain tooth point defect detection device includes a left block 1, a right block 2, an optical fiber detection mechanism 3, an electrical detection mechanism 4 and a control mechanism. The position of the left block 1 is fixed, and the left block 1 can be directly fixedly arranged on the dental implant machine. The left side block 1 is provided with a guide rod 11, and the right side block 2 is movably assembled on the guide rod 11, preferably two guide rods 11 are provided, which is conducive to the stable sliding of the right side block 2. Continue to refer to figure 1 , the guide rod 11 is equipped with a second compression spring 12, the second compression spring 12 is used to push the right side block 2 to the left side block 1; When the thickness of the belt 5 is relatively large, it can s...

The invention relates to a detection device and method for tooth point defects of metal chain teeth. The detection device comprises a left side block, a right side block, an optical fiber detection mechanism, an electric detection mechanism and a control mechanism. The detection method comprises the following steps: conveying a chain belt to be detected into a chain belt channel; sequentially transmitting a signal A sent by the electric detection mechanism to a left lead wire, the left side block, the chain teeth, a connector, a first compressed spring and a right lead wire to form a loop; receiving the signal A by the control mechanism; meanwhile, transmitting an optical signal sent by an optical signal generator of the optical fiber detection mechanism to a right optical fiber from a left optical fiber; if the right optical fiber receives the optical signal, receiving a signal B by the control mechanism to show that the chain teeth are not qualified; and if the left end face of the right optical fiber is shielded by the chain teeth and the optical signal cannot be received, receiving a signal C by the control mechanism to show that the chain teeth are qualified. According to the detection device and method, whether the produced metal chain teeth are a qualified product can be detected in time and the coping work is done in time, so that the reject rate is reduced, the standardization of the specification of a product is improved and the quality of the product is improved.
Description
technical field [0001] The invention relates to a device and a detection method for detecting defects of metal chain teeth by optical means and mechanical means, in particular to a detection device and detection method for point defects of metal chain teeth. Background technique [0002] At present, the metal zippers in the market are all formed by stamping. It uses a punching needle to impact a specific part of the chain element to form a specified shape and then form the chain element. Such a problem often occurs in actual production, that is, if the head of the punching needle of the stamping mechanism breaks, the height of the punched-out chain teeth directly affects the physical properties of the zipper. Waste products cause a large amount of waste of materials and high production costs. At present, some enterprises solve the above problems by installing an online imaging detection system, but due to the small size of the chain teeth, the detection accuracy of the dete...
