Description

Technical Field

[0001] The invention relates to the technical field of leakage detection, and in particular to a mobile phone wiring harness leakage detection device. Background Art

[0002] The mobile phone wiring harness is a small bundle of wires that connects the various components inside the mobile phone (such as the battery, display, motherboard, etc.). It is responsible for transmitting electrical signals and power to ensure the normal operation of all parts of the mobile phone. As mobile phone designs become increasingly compact and complex, high-quality wiring harnesses are essential to ensure the stability and reliability of the equipment. In order to ensure the quality of the mobile phone wiring harness, the wiring harness needs to be individually tested for electrical performance before it is installed in the mobile phone to ensure that each component meets electrical safety standards. This step helps to detect and eliminate defective wiring harnesses early, prevent unqualified parts from entering the next production link, and improve the quality of the final product. For example, a wiring harness leakage detection device disclosed in application number CN202311547956.9 detects whether the wiring harness is leaking.

[0003] The existing method of detecting whether the mobile phone wiring harness has leakage is to use a megohmmeter to measure the insulation resistance of the wiring harness. Under normal circumstances, the insulation resistance should be very high. If the resistance value is low, it may indicate leakage. Although this method can detect whether the wiring harness has leakage, there will be multiple wires in a set of wiring harnesses. For large-scale wiring harness leakage detection, it is necessary to detect them one by one. Detecting the wiring harnesses one by one is not only time-consuming, but also requires a lot of human resources, especially when the detection needs to be completed quickly on the production line or maintenance site. This method is less efficient, and the detection according to the above method can only detect whether the wiring harness has leakage, and cannot determine the specific leakage location of the wiring harness, which is not convenient for subsequent processing. Summary of the invention

[0039] The holding frame 12 is clamped and fixed by the following structure, refer to Figure 6 , Figure 7, also includes an operating panel 1, the top of the operating panel 1 is fixedly connected to a support frame 2, a transmission structure 5 is arranged in the support frame 2, the transmission structure 5 includes a transmission belt 51 for transmission, a plurality of storage slots 6 are opened at the top of the transmission belt 51, each inner peripheral wall of the storage slots 6 is opened with a fixing slot 7, the inner wall of the fixing slot 7 is fixedly connected to a flexible electromagnetic plate 8, the inner wall of the fixing slot 7 is fixedly connected to two symmetrical first springs 9, the other end of the first spring 9 is fixedly connected to a flexible extrusion block 10, the outer wall of the flexible extrusion block 10 close to the flexible electromagnetic plate 8 is fixedly connected to a flexible permanent magnet block 11 that magnetically repels the flexible electromagnetic plate 8, wherein in order to prevent the transmission belt 51 from encountering obstacles when turning, all components in the transmission belt 51 are flexible.

[0040] A holding frame 12 is placed in the storage slot 6. The holding frame 12 is made of magnetic isolation material, and the flexible extrusion block 10 is in contact with the holding frame 12. A placement slot 13 is provided on the inner bottom wall of the holding frame 12. The placement slot 13 includes two power-on slots 131, two terminal slots 132, and multiple harness slots 133. The power-on slots 131 are communicated with the terminal slots 132, and the terminal slots 132 are communicated with the harness slots 133. Two symmetrical second springs 14 are fixedly connected to the inner wall of the power-on slot 131. The other ends of the two second springs 14 are fixedly connected to a power-on plug 15 for energizing the harness. The terminal slots 132 are used to place terminals to prevent damage to the terminals. There is also a slot for placing extruded terminals at the bottom end of the detection frame 39.

[0041] The working principle of the present invention is as follows:

[0042] First, manually place the wiring harness into the placement slot 13, pull the power plug 15 backward, and then place the terminal of the wiring harness into the terminal slot 132, then release the power plug 15 and insert the power plug 15 into the terminal to facilitate the subsequent power-on of the wiring harness, place each wire in the wiring harness slot 133 in turn, and then place the containing frame 12 into the storage slot 6, and then power on the flexible electromagnetic plate 8. The repulsive force generated by the flexible electromagnetic plate 8 after powering on causes the flexible permanent magnet block 11 to drive the flexible extrusion block 10 to fix the containing frame 12, and then start the transmission structure 5, and after a certain period of time, close the transmission structure 5 (this time is the time for the placement slot 13 to move to the bottom of the detection frame 39 after pre-testing, and this technology is prior art and will not be elaborated here).

[0043] Then, the second multi-stage electric telescopic rod 38 is started, and the detection frame 39 is driven to move downward by the second multi-stage electric telescopic rod 38 (the limit distance of the second multi-stage electric telescopic rod 38 moving downward is just that the long thermistor 31 contacts the wiring harness but does not squeeze the wiring harness), and then the power plug 15 is energized to energize the wiring harness (the duration of each power-on is pre-tested, and the time of wiring harness leakage can be fully detected). As the wiring harness is energized, the leakage part of the wiring harness will slowly heat up. The reason for the heating of the leakage part of the wiring harness is that due to the damage of the insulation layer or poor contact, the current flows through an abnormal path, and these paths usually have a large resistance. Under normal circumstances, the current is evenly distributed inside the wiring harness, but when leakage occurs somewhere, the current will be concentrated through the damaged or poorly contacted place, resulting in an increase in current density, which further increases the resistance and heat generation of the part. The larger resistance means that more electrical energy is converted into heat energy, causing the part to heat up;

[0044] Therefore, when there is a leakage part in the wiring harness, the heat generated at the leakage part will be conducted to the long thermistor 31. After the long thermistor 31 senses the heat, its resistance will change. When the resistance changes, the current passed into the current detection module in the PLC controller 16 will change accordingly. When the PLC controller 16 detects the current change, the first motor 310 is controlled by the PLC controller 16 to start, and the first threaded rod 311 is driven to rotate by the first motor 310. Then, the extension block 34 is moved on the first limit rod 312 through the limit of the first limit rod 312, thereby driving the first conductive sheet 32 ​​to slide on the surface of the long thermistor 31. When the first conductive sheet 32 ​​does not move to the long thermistor, the extension block 34 is moved on the first limit rod 312. When the resistor 31 senses heat, since the first conductive sheet 32 ​​contacts the unheated area, the resistance value does not change much. As the first conductive sheet 32 ​​moves, its resistance value gradually increases because the first conductive sheet 32 ​​is getting closer and closer to the heated area. When the conductive sheet contacts the heated area, the temperature of the area increases, and the resistance value of the long thermistor 31 increases significantly. As the first conductive sheet 32 ​​gradually moves away from the heated part of the long thermistor 31, the temperature of the long thermistor 31 begins to drop. Therefore, the measured resistance value gradually decreases. When the current detection module detects that the current is reduced, the first motor 310 is controlled by the PLC controller 16 to reversely drive the first threaded rod 311.

[0045] Since the position of the strip thermistor 31 with the highest resistance value has been detected during the movement of the first conductive sheet 32, the first threaded rod 311 is driven in reverse to make the first conductive sheet 32 ​​move in reverse. When the first conductive sheet 32 ​​moves to the position of the strip thermistor 31 with the highest resistance value, the first motor 310 is controlled to stop running by the PLC controller 16. During the movement of the first conductive sheet 32, the second conductive sheet 36 is driven to move synchronously on the first resistor plate 37 through the insulating block 33. Then, the current of the second conductive sheet 36 passing through the first sliding rheostat at this position is detected by the current detection module. Then, the current data is recorded, and the infrared emitter 35 of the strip thermistor 31 corresponding to the detected heat is controlled to turn on by the PLC controller 16.

[0046] Then the second multi-stage electric extension rod is controlled to reset, and the infrared transmitter 35 is started at the same time, and then the second motor 49 is controlled to start through the PLC controller 16, and the second threaded rod 410 is driven to rotate through the second motor 49, and then the moving block 41 is moved on the second limiting rod 411 through the limiting of the second limiting rod 411, thereby driving the third conductive sheet 42 to slide on the second resistor plate 43 (because the second resistor plate 43 is completely consistent with the first resistor plate 37, the resistance values ​​at various locations are also consistent). When the current detection module detects that the current passing through the second sliding rheostat is consistent with the current value recorded above, this is the location where the wiring harness is leaking, and then the second motor 49 is controlled to stop running through the PLC controller 16, and then the electric hydraulic telescopic rod 44 is started, and the extension plate 45 is driven forward by the hydraulic electric telescopic rod. When When the infrared receiver 48 at the top of the extension plate 45 receives infrared rays, it means that the wiring harness at that location is leaking. Since the infrared transmitter 35 is not at the same center as the long strip thermistor, the electric hydraulic telescopic rod 44 needs to be retracted to a certain distance to locate the wiring harness (this distance has been written into the PLC controller 16 in advance), and the long strip thermistor of the infrared transmitter 35 is fixed, so the electric hydraulic telescopic rod 44 can be controlled by the PLC controller 16 to retract the above distance, and then the first multi-stage electric telescopic rod 46 is controlled by the PLC controller 16 to push the electromagnetic booster nozzle 47 to move downward, and then the first multi-stage electric telescopic rod 46 is started, and the electromagnetic booster nozzle 47 is used to spray fluorescent white paint on the surface of the wiring harness to mark it for subsequent processing, and then the electromagnetic booster nozzle 47 is immediately closed.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
