Description

Technical Field

[0001] This utility model relates to the field of feeder testing technology, and in particular to a feeder continuity testing device. Background Technology

[0002] Continuity testing is a crucial step in feeder inspection and a vital method for verifying the connection performance of the inner and outer conductors. Currently, the MQ series feeder continuity testing uses a simple continuity test box for manual testing. The principle involves a simple circuit using a dry cell battery and a series buzzer. Two test leads are used to test the beginning and end of the feeder to determine the corresponding wire sequence. After the buzzer sounds, the corresponding label number is manually affixed; these labels are pre-attached to a shelf in front of the workbench. The number of feeders varies for each specification, ranging from 2 to 5. The continuity of each feeder is manually measured at both ends, and the corresponding label number is affixed afterward.

[0003] However, manually testing feeders using a simple continuity test box has the following drawbacks: 1. Manual testing requires testing both ends of the feeder simultaneously, and the feeder is relatively rigid and not easily bent, making single-person operation cumbersome and inconvenient; 2. Labels need to be affixed while testing the feeder. These labels need to be printed in advance and affixed to the workbench, posing a risk of incorrect handling or affixing, which can easily lead to customer complaints; 3. The handling and affixing of labels requires manual identification, which can cause fatigue over long periods; 4. Manually testing each wire individually requires recording the specific faulty wire, posing a risk of misrecording and increasing subsequent defect risks and manufacturing costs. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a feeder continuity testing device that can perform feeder continuity testing stably, accurately and quickly.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model provides a feeder continuity detection device, which is used in conjunction with a printing device and a feeder. The feeder continuity detection device includes:

[0007] The device body includes a housing, inside which a signal processing unit is housed. The housing also has an interface unit and a voice broadcast unit, which are electrically connected to the signal processing unit. The interface unit includes a first signal output interface, a second signal output interface, a signal input interface, and a power interface, all of which are electrically connected to the signal processing unit.

[0010] The number of core wires corresponding to different types of feeders is different, and different types of feeders are matched with different types of adapter cables. When the feeder is in the detection state, the signal processing unit, the second signal output interface, the test probe, the feeder, the adapter cable, the signal input interface, and the signal processing unit are sequentially electrically connected to form a test circuit.

[0011] Furthermore, the feed line includes multiple core wires, which sequentially and individually contact the test terminals of the test probes.

[0026] Compared with existing technologies, the advantages of this utility model are:

[0027] The testing equipment described in this application can perform stable, accurate, and rapid continuity testing on feeders. The input end of the feeder to be tested is pre-connected via an adapter cable, and the other end of the core wire only needs to be tested by contacting the test probes in sequence.

In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0038] like Figure 1 As shown, this utility model provides a feeder continuity testing device, used in conjunction with a printing device 40 and a feeder 60. The feeder continuity testing device may include a device body 10, an adapter cable 20, and test probes 30. The device body 10 includes a housing, inside which is a signal processing unit. The housing also has an interface unit and a voice broadcast unit, which are electrically connected to the signal processing unit. The interface unit may include a first signal output interface 14, a second signal output interface 15, a signal input interface 13, and a power interface 16, which are electrically connected to the signal processing unit. The first signal output interface 14 is electrically connected to the printing device 40, and the power interface 16 is connected to a power source. The voice broadcast unit may be, for example, a speaker 11. The test probes 30 include a common terminal and a test terminal. The common terminal of the test probes 30 is electrically connected to the second signal output interface 15, and the test terminal of the test probes 30 is electrically connected to the first end of the feeder 60. The adapter cable 20 includes a cable body and connectors at both ends of the cable body. The connector at one end of the cable body is electrically connected to the second end of the feeder 60, and the connector at the other end of the cable body is electrically connected to the signal input interface 13.

[0039] Different types of feeders 60 have different numbers of core wires, and different types of feeders 60 are matched with different types of adapter cables 20. For example, the second signal output interface 15 and the signal input interface 13 can be five-pin aviation connectors. One five-pin aviation connector (signal input interface 13) has its inner end connected to the signal processing unit, and its outer end connected to the input end of the feeder 60 under test; the other five-pin aviation connector (second signal output interface 15) has its inner end electrically connected to the inner end of the five-pin aviation connector of the signal input interface 13, and its outer end connected to the common end of the test probe 30. Thus, during testing, the input end of the feeder 60 is connected to the signal input interface 13 (five-pin aviation connector), and the output end of the feeder 60 is connected to the test end of the test probe 30, forming a closed loop. Furthermore, to adapt to the connection testing of different types of feeders, such as five-core feeders, four-core feeders, and three-core feeders, such as... Figure 2 , Figure 3 as well as Figure 4 As shown, the adapter cable 20 can be configured as a five-core, four-core, or three-core cable. Each core wire in the cable has a unique wiring sequence, and five-pin connectors are installed at both ends of the cable. The end of each core wire connects to the corresponding pin of the five-pin connector. For example, the two ends of core wire 1 connect to pin 1 of the five-pin connectors at both ends, the two ends of core wire 2 connect to pin 2 of the five-pin connectors at both ends, and so on. Thus, the two ends of the adapter cable 20 can be conveniently and quickly connected to the feeder 60 and the signal input interface 13 via five-pin connectors.

[0040] It should be noted that a corresponding five-pin connector can be pre-soldered at one end of the feeder 60 connecting to the adapter cable 20, so that the five-pin connector at the end of the adapter cable 20 can be connected for testing later.

[0041] When the feeder 60 is in the detection state, the signal processing unit, the second signal output interface, the test probe 30, the feeder 30, the adapter cable 20, the signal input interface 13, and the signal processing unit are sequentially electrically connected to form a test circuit.

[0042] Specifically, during testing, the common terminal of the test probe 30 is connected to the second signal output interface 15. The feeder line 60 includes multiple core wires. One end of the feeder line 60 is connected to the signal input interface 13 via an adapter cable 20, while the other end has multiple core wires exposed. These core wires are sequentially and individually contacted with the test terminals of the test probe 30 for continuity testing until all core wires on the feeder line 60 have been tested. Each core wire has a corresponding wire sequence, meaning that each core wire will provide a corresponding wire sequence signal when it is conducting. Furthermore, the number of core wires in the feeder line 60 matches the type of the cable body; that is, the number of core wires in the cable body of different types of adapter cables 20 corresponds to the number of core wires in the feeder line 60. This allows different types of feeder lines 60 to be tested using different adapter cables 20.

[0043] When the feeder is in detection mode, if the signal processing unit receives an input signal, it processes the signal and identifies the wire sequence (e.g., 1, 2, 3, 4, 5, etc.) to obtain the corresponding test result. Based on the test result, the signal processing unit sends a signal to the printing device to print the wire sequence of each wire sequentially and to the voice broadcast unit to announce the corresponding wire sequence. In this case, the corresponding wire is determined to be normal. If the signal processing unit does not receive an input signal, it either does not send a signal to the printing device or the voice broadcast unit, or it sends a signal to the voice broadcast unit to issue an alarm. In this case, the corresponding wire is determined to be faulty. As an example, the printing device can be printer 40.

[0044] The testing equipment of this application can perform stable, accurate, and rapid continuity testing on feeders. The input end of the feeder to be tested is pre-connected via adapter cable 20, and the other end of the core wire only needs to be tested by sequentially contacting it with the test probes 30. During testing, there is no need to manually connect the beginning and end of the feeder simultaneously, making it easy to operate. Furthermore, the signal processing unit quickly and accurately identifies the wire sequence number based on the received signal and sends the identification information to the printing device in real time to print labels, making it more convenient to affix labels to the core wires. The signal processing unit sends the identification information to the voice broadcast unit to announce the corresponding wire sequence, ensuring the accuracy of manually recorded results and effectively improving testing efficiency.

[0045] As an example, such as Figure 1 and Figure 5 As shown, the housing is a cuboid. An interface unit, namely a first signal output interface 14, a second signal output interface 15, a signal input interface 13, and a power interface 16, is provided on one vertical side wall of the housing. A voice broadcast unit, namely a speaker 11, is provided on the other vertical side wall of the housing.

[0046] As an example, such as Figure 1 and Figure 5As shown, the first signal output interface 14 is a USB interface. That is, the inner end of the USB interface is connected to the signal processing unit, and the outer end is connected to the printer 40 via a USB cable to achieve the transmission of printing signals.

[0047] As an example, it also includes a communication unit located inside the housing, which is electrically connected to the signal processing unit and the USB interface.

[0048] Specifically, such as Figure 6 As shown, the signal processing unit transmits control information to the printing device (i.e., the printer) via the communication unit. The communication unit can use PLC serial communication, and its detection principle is as follows: Figure 7 As shown, the PLC input point X is connected to the signal input interface, which connects to the input terminal of the corresponding test feeder. The signal output interface connects to the common terminal of the test leads, forming a loop after contact with the PLC input point X. PLC signal processing includes continuity loop verification, X-point signal input and loop determination, output point Y controlling speaker announcement, and sending the identified input signal channel information to the printer via PLC serial communication. The printer receives the printing information and prints digital labels online. The printer driver is installed on the computer, and the PLC serial port communicates with the computer driver software to receive the printing information. The speaker receives the PLC output point Y signal, triggering voice announcement for the corresponding channel. The speaker has five voice announcement channels (channels 1-5), and triggering a specific channel will announce the corresponding line number. The HMI displays the currently tested number and provides a prompt.

[0049] As an example, such as Figure 1 As shown, it also includes a display unit, namely a monitor 50, which is connected to the USB interface 14 and the printing device 40. The monitor 50 has a built-in human-machine interface and is used to display the wire sequence number for manual identification and recording. When the signal processing unit determines the wire sequence number of the core wire in the feeder 60 corresponding to the conducting signal, it sends information to the monitor 50 for real-time display. Furthermore, the printer 40 can be connected to the monitor 50 via a USB cable to receive control signals from the signal processing unit through the monitor 50 (which can be an all-in-one display).

[0050] As an example, such as Figure 1 As shown, a touch screen 12 is also provided on the housing of the device body 10. The touch screen 12 and the voice broadcast unit (i.e., speaker 11) are located on the same side wall. Specifically, on the one hand, the touch screen 12 can realize the display of test status, including displaying the number indication of the feeder line sequence being tested, and the communication status display; on the other hand, the label content corresponding to the line sequence number can be set through the touch screen 12; finally, the feeder test output can be statistically analyzed through the touch screen 12.

[0051] This utility model discloses a feeder continuity testing device. It identifies and connects the beginning and end of the feeder (i.e., connects the two ends of each core wire in the feeder to the corresponding numbered pins of a five-pin connector, ensuring the core wire's own sequence matches the pin numbers at both ends, thus enabling subsequent continuity detection based on the corresponding core wire sequence information, improving testing efficiency). It automatically detects feeder continuity and the corresponding wire sequence. Through PLC communication, it controls a label printer to automatically print the corresponding test wire sequence number. The printed labels are then manually picked up and pasted onto the test feeder. This reduces label pasting errors by 0.4% and improves efficiency by over 20%. This feeder continuity testing device achieves semi-automation and intelligent operation, is compatible with 28 products including MQ4 and MQ5, and is widely used in all feeder products. It enables continuity testing of different circuits and achieves intelligent detection and label printing through online printing and voice broadcast functions.

[0052] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
