Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of machinery, in particular to a deep hole plate electric spark leakage detection tool. Background Art
[0002] Traditional spark testers can periodically load a set voltage value onto the insulating wire, with the conductor part grounded, thereby forming a voltage difference between the conductor and the insulating surface. When there is a break or a pinhole, there is a leakage current between the two electrodes. The size of the leakage current determines whether an alarm is triggered, thereby detecting whether the insulation layer is defective and ensuring that the product is qualified before leaving the factory.
[0003] Since deep-hole plate products have 96 deep holes, it takes 60 seconds to manually visually inspect whether the product has broken skin or pinholes, and the detection accuracy is only 70-80%, which is inefficient and difficult to guarantee. In addition, traditional spark testing machines cannot be directly applied to leakage detection of deep-hole plate products. Discharge modules and receiving modules must be newly manufactured according to the structural shape of the product; and the high-voltage current generated by the high-voltage generator of the spark detection machine will instantly affect the voltage of the power cabinet, which will have a certain impact on the injection molding machine produced, and a voltage stabilizer must be added; at the same time, the spark detection machine must be interlocked with the manipulator, using the manipulator's movement to place and remove products, and at the same time isolate and classify the captured NG products.

[0017] When using the utility model, a manipulator is used to take out the product in the mold, and prevent the product from being placed on the high-voltage generator discharge module 7. After the photoelectric sensor located at the position of the high-voltage generator discharge module 7 receives the product placement signal, the signal is transmitted to the PLC controller. The PLC controller controls the motor 3 to start, and the lead screw pair is used to drive the high-voltage generator discharge module 7 to move to the bottom of the discharge receiving module 6.

The PLC controller determines whether the product is OK or NG according to the digital signal, and finally outputs the signal to the manipulator. The manipulator takes out the product and places it in a classified manner, and then enters the next cycle.
