[0002] At present, in the electroplating process of PCB (Printed Circuit Board), it is necessary to use a hanger to hang the PCB on an electrode plate for conducting current, and then immerse the hanger with the PCB in the electroplating solution through the electroplating equipment, so that the electroplating solution is evenly distributed on the surface of the PCB and the PCB is electroplated. When the hanger with the PCB is abnormal and jumps out of the electroplating solution, it will cause the PCB electroplating work to fail and reduce the production quality of the PCB. At present, an infrared sensing detection device is usually used to detect whether the hanger jumps abnormally. An infrared transmitter arranged on one side of the electroplating cylinder transmits an infrared signal, and then an infrared receiver arranged on the other side of the electroplating cylinder receives the infrared signal to detect whether the hanger in the electroplating cylinder jumps abnormally. However, the infrared sensing detection device is easily affected by the vibration of the electroplating unit, resulting in the deviation or change of the corresponding angle between the infrared transmitter and the infrared receiver, causing the infrared sensing detection device to easily have a detection judgment error or a detection failure, which is difficult to meet the needs of high-quality electroplating of PCB.

[0040] Please also read Figure 1 , Figure 5 and Figure 13 to Figure 14 , the detection device for abnormal jump of the hanger provided by the present invention is now described. The detection device for abnormal jump of the hanger provided by the present invention comprises a detection component 1 for detecting whether the hanger 4 jumps abnormally, and a support component 2 for suspending the detection component 1 above the hanger 4, the detection component 1 comprises at least two conductive cords 11 for the hanger 4 to touch when it jumps, and any two conductive cords 11 are arranged in parallel and spaced apart; the support component 2 comprises at least two support seats 21 spaced apart on the same side of the electroplating cylinder 3, and each support seat 21 is equipped with a support arm 22 for supporting each conductive cord 11 and extending above the electroplating cylinder 3 to suspend each conductive cord 11 above the hanger 4.

[0041] Compared with the prior art, the detection device for abnormal jumping of the hanger provided by the present invention has at least two support seats 21 spaced apart on the same side of the electroplating cylinder 3, and each support seat 21 is equipped with a support arm 22 for supporting each conductive rope 11 for the hanger 4 to jump up and touch to the top of the electroplating cylinder 3. Any two conductive ropes 11 arranged in parallel and spaced apart will not be electrically conductive. When the hanger 4 in the electroplating cylinder 3 jumps up abnormally and touches any two conductive ropes 11, electrical conduction occurs between the two conductive ropes 11, triggering the controller to control the shutdown action, thereby accurately detecting the abnormal jumping of the hanger 4 in the electroplating cylinder 3, solving the problem of easy detection judgment errors or detection failures in the infrared sensing detection device in the prior art when detecting whether the hanger 4 in the electroplating cylinder 3 jumps up abnormally.

As long as the hanger 4 in the electroplating tank 3 jumps up abnormally, the metal conductive hanger 4 will jump up and touch each conductive cord 11 at the same time to electrically conduct and trigger the controller to control the shutdown control, thereby achieving the purpose of accurately detecting whether the hanger 4 in the electroplating tank 3 jumps up abnormally. Fig.10 As shown in FIG12 , when it is detected that the hanger 4 in the electroplating cylinder 3 jumps up abnormally and causes a jamming phenomenon, and it is necessary to remove the hanger 4 that jumps up abnormally from the electroplating cylinder 3, the locking effect on the movable arm 23 can be cancelled by rotating the rotation locking member 25 to disengage the movable arm 23, and the movable arm 23 can rotate around the rotation axis 24 to a position where each conductive cord 11 is kept in a relaxed state, and the end of the movable arm 23 connected to each conductive cord 11 is pulled to drive each conductive cord 11 to be out of the position blocking the hanger 4, so that the abnormal hanger 4 can be conveniently and quickly removed from the electroplating cylinder 3. After the abnormal hanger 4 is removed and restored to normal, the movable arm 23 is rotated again to a position where each conductive cord 11 is kept in a stretched and taut state, and then through the locking effect of the locking member 25, the movable arm 23 can be pulled to drive each conductive cord 11 to be located again at a position for the hanger 4 to jump up and touch, so that whether the hanger 4 in the electroplating cylinder 3 jumps up abnormally can be detected.
