Description

Technical Field

[0001] This application belongs to the field of instrument testing technology, specifically relating to an automated calibration device for electrical instruments. Background Technology

[0002] Electrical instruments are automated technology tools composed of several electrical components, possessing relatively complete functions. They generally have multiple functions simultaneously, such as measurement, display, recording, or measurement, control, and alarm. An automated instrument is both a system itself and a subsystem within an overall automation system. An automated instrument is an "information machine," whose main function is the conversion of information forms, transforming input signals into output signals. Signals can be expressed in the time domain or frequency domain, and signal transmission can be modulated into continuous analog quantities or intermittent digital quantities. They are instruments used to measure, display, control, and record electrical parameters (such as voltage, current, resistance, power, frequency, etc.) and non-electrical parameters (such as temperature, pressure, flow rate, liquid level, etc.), and are widely used in industrial production, power systems, scientific research experiments, energy management, and other fields.

[0003] Currently, electrical instruments need to be tested and calibrated during production to determine their qualification. However, in existing technologies, electrical instruments are usually tested and calibrated manually. In practice, it has been found that manual testing is inefficient and prone to errors. Utility Model Content

[0004] The purpose of this application is to provide an automated calibration device for electrical instruments to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] An automated calibration device for electrical instruments includes: a calibration table and a robotic arm disposed on one side of the top of the calibration table, a clamping assembly disposed on one side of the robotic arm, and a connecting assembly disposed on one side of the clamping assembly.

[0007] The clamping assembly includes a detection platform, a groove is provided on the top of the detection platform, a touch switch is installed inside the groove, multiple hinge seats are symmetrically installed on the side of the detection platform, clamping claws are rotatably connected to the inner side of each of the multiple hinge seats, connecting rods are rotatably connected to the ends of each of the multiple clamping claws, and a moving platform is rotatably connected to the ends of each of the multiple connecting rods. An electric telescopic rod is provided at the bottom of the moving platform.

[0008] The connecting assembly includes a mounting platform, on the top of which is mounted an electric telescopic rod II. The telescopic end of the electric telescopic rod II is fixedly connected to a mounting plate. Multiple buffers are symmetrically mounted on the mounting plate, and buffer plates are mounted at the ends of the multiple buffers. Connectors are mounted on the buffer plates.

[0009] Preferably, the robotic arm is positioned on one side of the testing platform, the mounting platform is positioned on one side of the testing platform, and the tops of the testing platform and the mounting platform are flush.

[0010] Preferably, the groove is located in the middle of the testing platform, and one bottom of the electric telescopic rod is installed below the calibration platform.

[0011] Preferably, the movable stage is located at the bottom of the testing platform, and the movable stage is installed at the telescopic end of the electric telescopic rod.

[0012] Preferably, the plurality of gripping claws are equidistantly arranged around the detection table, and the tips of the plurality of gripping claws extend to the top of the detection table.

[0013] Preferably, the connector is disposed between multiple gripping claws and is disposed on one side of the testing table.

[0014] Compared with the prior art, the beneficial effects of this application are:

[0015] (1) By designing a robotic arm, clamping components and connecting components, during the production of electrical instruments, the robotic arm grabs the electrical instruments on the production line and places them on the top of the testing platform. Multiple clamping claws fix the electrical instruments of different sizes placed on the top of the testing platform. Finally, the electric telescopic rod II drives the mounting plate to move, so that the connector is inserted into the electrical instrument, thereby enabling the automatic calibration of the electrical instrument and effectively improving the testing and calibration efficiency.

[0016] (2) By designing a clamping assembly, when calibrating electrical instruments, the electrical instruments are placed on the top of the testing platform, so that the electrical instruments press down the touch switch, and the touch switch controls the operation of the electric telescopic rod, which in turn drives the moving platform to move. The moving platform drives the connecting rod to rotate, which in turn drives multiple clamping claws to rotate, so that the multiple clamping claws fix the electrical instruments placed on the top of the testing platform. This design can clamp and fix electrical instruments of different sizes, which facilitates subsequent testing and calibration, and effectively improves the applicability and practicality of the device.

[0024] Example 1:

[0025] Please see Figure 1 As shown, an automated calibration device for electrical instruments includes: a calibration platform 1, a robotic arm 2 disposed on one side of the top of the calibration platform 1, a clamping assembly 3 disposed on one side of the robotic arm 2, and a connecting assembly 4 disposed on one side of the clamping assembly 3.

[0026] As can be seen from the above, during production, the robotic arm 2 grabs the electrical instruments on the production line, the clamping component 3 fixes the grabbed electrical instruments, and finally the connecting component 4 connects the wire harness to the electrical instruments, thereby automating the calibration of the electrical instruments.

[0027] Specifically, regarding the aforementioned clamping component 3, refer to... Figure 2 and Figure 3As shown, the clamping assembly 3 includes a detection table 31. The top of the detection table 31 has a groove 32. A touch switch 33 is installed inside the groove 32. Multiple hinge seats 34 are symmetrically installed on the side of the detection table 31. Clamping claws 35 are rotatably connected to the inner side of each of the multiple hinge seats 34. Linkage rods 36 are rotatably connected to the ends of each of the multiple clamping claws 35. A moving table 37 is rotatably connected to the ends of each of the multiple linking rods 36. An electric telescopic rod 38 is provided at the bottom of the moving table 37.

[0028] As can be seen from the above, when the electrical instrument is clamped and fixed, it is placed on the top of the testing platform 31. At this time, the electrical instrument presses down the touch switch 33, which controls the operation of the electric telescopic rod 38. The electric telescopic rod 38 drives the moving platform 37 to move, which in turn drives the connecting rod 36 to rotate. This, in turn, drives the multiple clamping claws 35 to rotate, allowing the multiple clamping claws 35 to fix electrical instruments of different sizes placed on the top of the testing platform 31, facilitating subsequent testing.

[0029] Specifically, regarding the aforementioned connection component 4, refer to... Figure 4 As shown, the connecting component 4 includes a mounting platform 41, an electric telescopic rod 42 is mounted on the top of the mounting platform 41, a mounting plate 43 is fixedly connected to the telescopic end of the electric telescopic rod 42, a plurality of buffers 44 are symmetrically mounted on the mounting plate 43, a buffer plate 45 is mounted at the end of the plurality of buffers 44, and a connector 46 is mounted on the buffer plate 45.

[0030] As can be seen from the above, after the electrical instrument is fixed, the mounting plate 43 is moved by the electric telescopic rod 42, so that the connector 46 is inserted into the electrical instrument. After the connector 46 is inserted, it is buffered by the buffer 44 and the buffer plate 45 to avoid damage to the device during the insertion.

[0031] Reference Figure 2 As shown, the robotic arm 2 is set on one side of the inspection table 31, and the mounting table 41 is set on one side of the inspection table 31, with the tops of the inspection table 31 and the mounting table 41 being level.

[0032] As can be seen from the above, by using the robotic arm 2 to grab the electrical instruments on the production line, the electrical instruments can be placed on the top of the testing table 31. At the same time, the top of the testing table 31 is flush with the top of the mounting table 41, so that the subsequent connector 46 can be plugged into the electrical instrument.

[0033] Reference Figure 3 As shown, the groove 32 is located in the middle of the testing platform 31, and the bottom of the electric telescopic rod 38 is installed below the calibration platform 1.

[0034] As can be seen from the above, the groove 32 is set in the middle of the test platform 31 so that the electrical instrument can be placed to trigger the touch switch inside the groove 32. At the same time, the electric telescopic rod 38 is installed under the calibration platform 1 to facilitate the subsequent movement of the electric telescopic rod 38.

[0035] Reference Figure 3 As shown, the movable stage 37 is located at the bottom of the detection stage 31, and the movable stage 37 is installed at the telescopic end of the electric telescopic rod 38.

[0036] As can be seen from the above, the moving stage 37 is driven to move at the bottom of the testing stage 31 by the electric telescopic rod 38, so that the subsequent connecting rod 36 and the clamping claw 35 can rotate, which facilitates the clamping of electrical instruments.

[0037] Reference Figure 3 As shown, multiple gripping claws 35 are equidistantly arranged around the detection table 31, and the tops of the multiple gripping claws 35 extend to the top of the detection table 31.

[0038] As can be seen from the above, the electrical instruments placed on the top of the testing table 31 are clamped by multiple clamping claws 35. By controlling the degree of rotation of the clamping claws 35, electrical instruments of different sizes can be clamped and fixed.

[0039] Reference Figure 2 As shown, the connector 46 is disposed among the multiple gripping claws 35, and the connector 46 is disposed on one side of the detection table 31.

[0040] As can be seen from the above, by using multiple clamping claws 35 to clamp the electrical instrument, the clamping claws 35 will not interfere with the subsequent connector 46 when it is inserted and moved.

[0041] Example 2:

[0042] refer to Figure 2 As shown, the testing platform 31 is fixed to the calibration platform 1 by multiple columns. The testing platform 31 has corresponding slots. Connector 46 is connected to the calibration equipment (existing technology) via a data cable, and connector 46 is bolted to the buffer plate 45. In the idle areas of this device, all the aforementioned electrical components (referring to power elements, electrical components, and compatible controllers and power supplies) are connected via wires. The specific connection methods are described in the working principle below, where the electrical connections are completed according to the sequential operation of each component. The detailed connection methods are known in the art.

[0043] As can be seen from the above, the testing platform 31 is fixed on the calibration platform 1 by multiple columns, and the corresponding slots facilitate the subsequent adjustment of the multiple clamping claws 35. At the same time, by changing the connectors 46 of different models, it is convenient to be used with different models of electric instruments.

[0044] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
