[0034] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.
[0035] Refer to Figures 1 to 3, an embodiment of the present application provides a multimeter detection device, including a detection platform 100 and a multimeter detection device; the multimeter detection device includes a carrier 200, a probe test mechanism 300, a button test mechanism 400, and a reading acquisition mechanism 500, all of which are arranged on the detection platform 100; the carrier 200 is used to carry the multimeter 800 to be tested; the probe test mechanism 300 has a detection end, and this detection end is used to contact or separate from the detection probe of the multimeter 800 to be tested; the button test mechanism 400 is used to press or release the buttons of the multimeter 800 to be tested; the reading acquisition mechanism 500 is used to acquire the reading image of the multimeter 800 to be tested.
[0036] In practical applications, the multimeter 800 to be tested is placed on the carrier 200, and then by making the detection end of the probe test mechanism 300 contact the detection probe on the multimeter 800 to be tested, at this time a reading is generated on the multimeter 800 to be tested, and then the button test mechanism 400 can be used to press the buttons of the multimeter 800 to be tested to switch the mode of the multimeter 800 to be tested (such as switching from the voltage measurement mode to the current measurement mode), and then a reading is generated on the multimeter 800 to be tested to meet different usage requirements, and the reading on the multimeter 800 to be tested can be acquired by the reading acquisition mechanism 500 to facilitate confirming the measurement accuracy of the multimeter 800 to be tested; after the multimeter 800 to be tested is detected, it is reset through the button test mechanism 400 and the probe test mechanism 300, and after the current multimeter 800 to be tested is taken out, another multimeter 800 to be tested is placed on the carrier 200 for detection. In this way, through the mutual cooperation of the probe test mechanism 300, the button test mechanism 400, and the reading acquisition mechanism 500, the automatic detection of the multimeter 800 to be tested is realized, effectively improving the detection efficiency and detection accuracy.
[0037] In some embodiments, the probe test mechanism 300 includes a test contact 310 and a first driving member 320, both of which are arranged on one side of the carrier 200; the output end of the first driving member 320 is in transmission connection with the test contact 310, and is used to drive the test contact 310 to contact or separate from the detection probe of the multimeter 800 to be tested.
[0038] In this embodiment, the above-mentioned first driving member 320 can be a motor, a cylinder, a hydraulic cylinder, etc., and no specific limitation is made here.
[0039] When detecting the multimeter 800 to be tested, the first driving member 320 is used to drive the test contact 310 to move closer in the direction close to the multimeter 800 to be tested until the test contact 310 contacts the detection probe of the multimeter 800 to be tested, and at this time a reading is generated on the multimeter 800 to be tested.
[0040] Further, the test contact 310 is also electrically connected to the power supply to make the test contact 310 charged; thus, when the multimeter 800 to be tested is in a current measurement mode or a voltage measurement mode, current / voltage measurement can be performed.
[0041] In some embodiments, the multimeter detection device further includes a mounting platform 600 provided on the detection platform 100; the key test mechanism 400 includes a pressing head 410 and a second driving member 420 provided on the mounting platform 600, and the output end of the second driving member 420 is in transmission connection with the pressing head 410 for driving the pressing head 410 to press or release the keys of the multimeter 800 to be tested.
[0042] In this embodiment, the second driving member 420 may be a motor, a cylinder, a hydraulic cylinder, etc., which is not specifically limited herein.
[0043] When the multimeter 800 to be tested is detected, the second driving member 420 drives the pressing head 410 to approach in the direction close to the multimeter 800 to be tested until the pressing head 410 presses the keys on the multimeter 800 to be tested, thereby realizing inputting instructions to the multimeter 800 to be tested.
[0044] In some embodiments, the key test mechanism 400 further includes an elastic member 430 and a fixing plate 440 both provided on the side of the mounting platform 600 close to the detection platform 100; the pressing head 410 is provided on the side of the fixing plate 440 close to the detection platform 100, and the pressing head 410 includes a contact head 411 and a sliding portion 412 connected to each other, and the sliding portion 412 slidably penetrates through the fixing plate 440; the elastic member 430 is sleeved on the sliding portion 412, and both ends of the elastic member 430 are respectively in contact with the contact head 411 and the fixing plate 440; the output end of the second driving member 420 is fixedly connected to the fixing plate 440 for driving the fixing plate 440 to move so that the pressing head 410 presses or releases the keys of the multimeter 800 to be tested.
[0045] It can be understood that when the second driving member 420 drives the pressing head 410 to press the keys on the multimeter 800 to be tested, the pressing head 410 will be subjected to a reverse force from the keys on the multimeter 800 to be tested. At this time, the elastic member 430 deforms to buffer the reverse force to avoid hard contact between the pressing head 410 and the keys on the multimeter 800 to be tested, thereby avoiding contact wear between the pressing head 410 and the keys on the multimeter 800 to be tested.
[0046] Further, the elastic member 430 is a spring. After the spring receives the reverse force applied by the button on the multimeter 800 to be measured to the pressing head 410, elastic energy storage is formed. When the reverse force is no longer applied to the spring, the spring can use the elastic energy storage to drive its reset, so as to facilitate the next use of the button testing mechanism 400.
[0047] In some embodiments, the multimeter detection device includes a lifting mechanism 700; the lifting mechanism 700 includes a sliding guide column 710, a sliding sleeve 720, and a third driving member 730; the sliding guide column 710 is installed on the detection platform 100; the sliding sleeve 720 is slidably installed on the sliding guide column 710, and the sliding sleeve 720 is fixedly connected to the installation platform 600; the third driving member 730 is installed on the detection platform 100, and the output end of the third driving member 730 is connected to the installation platform 600 for driving the installation platform 600 to approach or move away from the detection platform 100.
[0048] In this embodiment, the third driving member 730 may be a motor, a cylinder, a hydraulic cylinder, etc., which is not specifically limited herein.
[0049] In practical applications, the installation platform 600 can be driven by the third driving member 730 to move in a direction close to the detection platform 100, so that the pressing head 410 on the installation platform 600 approaches the button on the multimeter 800 to be measured, so as to facilitate the subsequent driving of the pressing head 410 to press the button on the multimeter 800 to be measured by the second driving member 420. After the button testing mechanism 400 completes the detection, the installation platform 600 is driven by the third driving member 730 to move in a direction away from the detection platform 100, so that the installation platform 600 is reset. During the movement of the installation platform 600, the sliding sleeve 720 moves along the sliding guide column to improve the accuracy of the moving position of the installation platform 600. In this way, through the movement of the installation platform 600, it is not only convenient for the pressing head 410 on the installation platform 600 to press the button on the multimeter 800 to be measured, but also convenient for the operator to pick up and place the multimeter 800 to be measured on the carrying platform after the installation platform 600 is reset.
[0050] In some embodiments, the reading acquisition mechanism 500 is a vision detection mechanism.
[0051] Understandably, the vision detection mechanism includes a CCD camera, and the reading image on the multimeter 800 to be measured is collected by the CCD camera for the operator or the system to judge whether the reading of the multimeter 800 to be measured is correct.
[0052] In some embodiments, the number of the multimeter detection devices is multiple, and the multiple multimeter detection devices are arranged in an array on the detection platform 100. In this way, the multimeter detection device can simultaneously detect multiple multimeters 800 to be measured, and the detection of each multimeter detection device is independent of each other, thereby further improving the detection efficiency and flexibility of the multimeters 800 to be measured.
[0053] Obviously, the embodiments described above are only a part of the embodiments of the present application, rather than all the embodiments. The preferred embodiments of the present application are given in the drawings, but do not limit the patent scope of the present application. The present application can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosed content of the present application more thorough and comprehensive. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments, or perform equivalent replacements on some of the technical features. Any equivalent structure made by using the specification and drawings of the present application, directly or indirectly applied in other related technical fields, is equally within the scope of the patent protection of the present application.
