[0016] The following is a further detailed description of specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.

[0017] like Figure 1 and Figure 2The figure shows a schematic diagram of the structure of a multifunctional automatic high-frequency welding tongs wire electrical performance tester provided by the present invention. The multifunctional automatic high-frequency welding tongs wire electrical performance tester is used to test the electrical performance of a welding tongs wire. As is well known, the welding tongs wire comprises a cable, a copper conductor and a data cable disposed within the cable, a welding tongs arm disposed at one end of the cable, and a data connector and a power connector disposed at the other end of the cable. During use, the welding tongs arm is used to clamp solder. The power connector is connected to a power source, and the data connector is connected to a control device. The multifunctional automatic high-frequency welding tongs wire electrical performance tester comprises a machine platform 10, a welding tongs arm clamping mechanism 20 disposed on the machine platform 10, a power socket 30 disposed on the machine platform 20, a data socket 40 disposed on the machine platform 10, and a data acquisition and processing module 50 disposed on the machine platform 10. It is contemplated that the multifunctional automatic high-frequency welding tongs wire electrical performance tester may also include other functional modules, such as electrical connection components and electrical functional components such as switches and relays. These are well known to those skilled in the art and will not be described in detail here.

[0018] The machine 10 is used to carry the above-mentioned functional modules, such as the welding clamp arm clamping mechanism 20, the power socket 30, the data socket 40, etc. Therefore, its structure is suitable for carrying the above-mentioned functional modules and will not be described in detail here.

[0019] The welding clamp arm clamping mechanism 20 is used to clamp the welding clamp arm and includes a base 21, a clamping unit 22 disposed within the base 21, and a plurality of electrical contacts 23 disposed within the base 21. The base 21 is used to mount and secure the welding clamp arm, so a receiving slot 23 for mounting the welding clamp arm is provided within the base 21. The structure of this empty slot 23 is identical to that of the welding clamp arm being tested, and is therefore designed based on the actual structure of the welding clamp arm and will not be described in detail here. The clamping unit 22 is a lever-type clamping mechanism, a commonly used structure well known to those skilled in the art and will not be described in detail here. The electrical contacts 23 are used to abut against the electrical connections of the welding clamp arm, thereby conducting the welding clamp wires for testing when power is applied. The electrical contacts 23 may be elastic pins, also commonly used components well known to those skilled in the art and will not be described in detail here. When installing the welding clamp arm, the multiple electrical contacts 23 should be aligned and abutted against the corresponding electrical connection points of the welding clamp arm. In this embodiment, there are three electrical contacts 23, corresponding to the live wire, neutral wire, and data wire. Of course, the number of electrical contacts 23 can be increased or decreased according to actual needs.

[0020] The power socket 30 and data socket 40 are conventionally designed and correspond to the power and data connectors on the welding clamp cord, respectively. Therefore, the structure and operating principles of the power socket 30 and data socket 40 are well known to those skilled in the art and will not be further described here. During testing, the welding clamp arm, power connector, and data connector are sequentially attached to the welding clamp arm clamping mechanism 20, the power socket 30, and the data socket 40, respectively, and testing can begin.

[0021] The data acquisition processing module 50 includes a resistance tester 51, a circuit unit 52 electrically connected to the resistance tester 51, a switch unit 53 electrically connected to the resistance tester 51 and the circuit unit 52, and a processing unit 54 electrically connected to the resistance tester 51 and the switch unit 52.

[0022] The resistance tester 51 is used to detect the resistance of the connected welding clamp wire. This is prior art, an instrument for measuring the electrical conductivity of an object and widely used in applications such as electrical safety inspections. There are many types of resistance testers 51, such as ground resistance testers, insulation resistance testers, DC resistance testers, and loop resistance testers. In this embodiment, the resistance tester 51 is a DC resistance tester that automatically selects the test current based on the type of power transformer and displays the test results as quickly as possible. DC resistance testers have functions such as storage, printing, and discharge indication, and include a built-in non-power-down memory for long-term storage of measurement data. The resistance tester 51 is electrically connected to the circuit unit 52 via a probe B1 and a probe B2. During use, the resistance tester 51 can directly measure the resistance of the object under test in the circuit unit 52.

[0023] The circuit unit 52 is used to connect to the welding clamp cable and includes at least one parallel test group 521 and connection terminals 522 connected to each end of the test group 521. The number of test groups 521 is determined based on actual needs. In this embodiment, there are three test groups 521, and all three test groups 521 have identical components. Each test group 521 includes a switch 523 controlled by the switch unit 53 and two interfaces 524 connected in series with the switch 521. The switch 523 can be an electrically controlled switch that controls whether the DUT connected to the two interfaces 524 is tested. The two interfaces 524 are electrically connected to the DUT, and when powered on, they conduct electricity to the DUT for testing. In this embodiment, insulation testing and continuity testing are primarily performed. The methods for these tests are well known to those skilled in the art and primarily measure the resistance of the DUT. Initially, insulation and continuity test values are set. During the insulation test, if the resistance of the DUT exceeds the insulation test value, the insulation performance is considered to meet the standard. When the resistance of the object under test is less than the conductivity standard value during the conductivity test, the conductivity performance is considered to meet the standard. The terminal 522 is used to connect to the resistance tester 51 and is a common terminal, which will not be described in detail here.

[0024] The processing module 54 can be a microprocessor that is configured to set a standard resistance value and compare this standard resistance value with the resistance value output by the resistance tester 51 to output a comparison value indicating whether the resistance value output by the resistance tester 51 meets the standard. Specifically, the processing module 54 is configured to set the insulation standard value and the continuity standard value of the workpiece being tested. It is also configured to compare the measured insulation resistance value and the continuity resistance value of the workpiece being tested with the insulation standard value and the continuity standard value, respectively, and output a comparison value. Based on this comparison value, the processing module 54 determines whether the workpiece is qualified. Simultaneously, the processing module 54 transmits this comparison value to the switch unit 53, which determines whether to proceed to the next test based on the comparison value. If the comparison value meets the requirements, the workpiece is deemed qualified, and the next test item can be performed. If the comparison value does not meet the requirements, the workpiece is deemed unqualified, and the next test item does not need to be performed. It is contemplated that the comparison value can be either NG or No.

[0025] The switch unit 53 is used to control the on / off state of the circuit unit 51 based on the comparison value. It includes at least one relay 531 and a programmable logic controller (PLC) 532 for controlling the on / off state of the relay 531. The relay 531 itself is conventional and will not be described in detail here. It is used to control the on / off state of the switch 521. The PLC 532 controls the on / off state of the relay 531 based on the comparison value output by the processing module 54. The PLC 532 is conventional and can be programmed to generate control commands to control the on / off state of the relay 531, thereby controlling the on / off state of the switch 521.

[0026] It can be imagined that through the above description, those skilled in the art should be able to design the circuit shown in this utility model according to the spirit disclosed by this utility model.

[0027] In addition, the multifunctional automatic high-frequency welding clamp wire electrical performance tester may further include a display unit electrically connected to the processing module 54. When the processing module 54 outputs a comparison value, such as NG or No, it may be directly displayed on the display unit, such as a display screen, for easy value identification.

[0028] Compared to the prior art, the multifunctional automatic high-frequency welding clamp wire electrical performance testing device disclosed in the present invention uses the resistance tester 51 to obtain the resistance value of the workpiece being tested. This resistance value is transmitted to the processing module 54, which compares the resistance value with a standard resistance value to generate a comparison value. This comparison value is then sent to the switch unit 53 to control whether the circuit unit 52 performs the next test. This simple and fast process saves manpower and time. Furthermore, by providing the welding clamp arm clamping mechanism 20, the power socket 30, and the data socket 40, testing can be started by manually installing the corresponding components of the welding clamp wire. This reduces labor time and improves production efficiency.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements or improvements within the spirit of the present invention are included in the scope of the claims of the present invention.
