Description

Technical Field

[0001] This utility model belongs to the field of high-voltage withstand voltage testing technology, and specifically relates to an automated withstand voltage testing device. Background Technology

[0002] Withstand voltage testing involves applying a rated voltage to electrical equipment, electronic components, or insulating materials to test their insulation performance and withstand capability. It is widely used in the power, electronics, and home appliance industries. Electrical enclosure withstand voltage testing involves applying an AC or DC current higher than the rated voltage to the enclosure or insulating components to test their insulation performance and resistance to electrical breakdown, ensuring that the equipment will not pose a safety hazard due to leakage current under normal operating conditions or fault conditions.

[0003] Existing withstand voltage testing equipment requires manual placement of the electrical enclosure in the test position. After confirming proper placement, the equipment operates by placing the test probe against the enclosure to begin the test. This process involves personnel being close to the test area, posing a high risk. Furthermore, testing different specifications of electrical enclosures or different locations on the enclosure requires changing the test terminals. The conventional approach is to remove the enclosure and install the necessary test terminal equipment, which presents an inconvenience in disassembly and assembly. Utility Model Content

[0005] Technical solution: In order to achieve the above objectives, this utility model provides an automated withstand voltage testing device, including: a chassis, a test platform disposed on the top surface of the chassis, and a test base and a gantry support provided on the test platform; The test base is provided with a set of test bases, the test bases are provided with lower test probes, and the test bases are provided with positioning grooves that fit the product under test; the product under test is precisely placed in the test position through the positioning grooves; The gantry support is equipped with an upper pressure plate, and the bottom surface of the upper pressure plate is equipped with an upper test probe. The upper part of the gantry support is equipped with a telescopic cylinder connected to the upper pressure plate. The inner side of the column of the gantry support is equipped with a linear guide rail. The two sides of the upper pressure plate are slidably connected to the linear guide rail through sliders. The telescopic cylinder can drive the upper pressure plate to move downward, and the upper test probe on the upper pressure plate acts on the product to be tested to start the test. The front end of the upper pressure plate is equipped with a set of photoelectric sensors, which are directly facing the positioning slot. The photoelectric sensors can monitor whether the product to be tested is placed in the correct position, and the equipment will be started for testing only after the product is in the correct position.

[0006] The top surface of the chassis is also equipped with a withstand voltage tester, which is connected to the lower test probe and the upper test probe respectively.

[0009] Furthermore, the upper cover is equipped with an emergency stop button and function buttons.

[0010] Furthermore, the chassis is equipped with an electrical control box that controls the entire device, and the front of the chassis has a drawer containing a keyboard for modifying test parameters.

[0011] Furthermore, the top surface of the chassis is also equipped with a three-color light for issuing alarms based on the test structure, and a display for showing test parameters and results.

[0012] Furthermore, the back of the chassis is equipped with the same cooling fan as the one inside the chassis.

[0013] Furthermore, the bottom of the chassis is equipped with casters.

[0014] As can be seen from the above technical solution, this utility model has the following beneficial effects: 1) This utility model provides an automated withstand voltage testing device. Test parameters can be set before testing, and the device uses an automatic feeding machine to feed the material. A photoelectric sensor detects whether the material is in place, and the withstand voltage test begins automatically once it is in place.

Detailed Implementation

[0017] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0018] like Figure 1-5 As shown: An automated withstand voltage testing device includes: a chassis 1, a test platform 2 disposed on the top surface of the chassis 1, and a test base 3 and a gantry support 4 disposed on the test platform 2; The test base 3 is provided with a set of test bases 31, the test bases 31 are provided with lower test probes 32, and the test bases 31 are provided with positioning grooves 33 that fit the product to be tested; The gantry support 4 is provided with an upper pressure plate 41, the bottom surface of the upper pressure plate 41 is provided with an upper test probe 42, the upper part of the gantry support 4 is provided with a telescopic cylinder 43 connected to the upper pressure plate 41, the inner side of the column of the gantry support 4 is provided with a linear guide rail, and the two sides of the upper pressure plate 41 are slidably connected to the linear guide rail through a slider. The front end of the upper pressure plate 41 is provided with a set of photoelectric sensors 44, and the photoelectric sensors 44 are directly facing the positioning groove 33; The top surface of the chassis 1 is also provided with a pressure resistance tester 5, which is connected to the lower test probe 32 and the upper test probe 42 respectively.

[0019] In this embodiment, the product to be tested is automatically fed by a robotic arm. The robotic arm places the product in the positioning slot 33, and the photoelectric sensor 44 on the upper pressure plate 41 detects whether the product is placed in place. Once in place, the robot issues a "test can start" command to automatically start the test.

[0020] In a preferred embodiment, the test bench 2 includes a box body 21 and an upper cover 22 that covers the box body 21. The upper cover 22 and the rear side of the box body 21 are connected by a hinge, and the two sides are connected by a snap lock. The housing 21 contains a set of hydraulic support rods 23. The tail of the hydraulic support rods 23 is rotatably mounted on the housing 21, and the head of the hydraulic support rod is rotatably connected to the inside of the upper cover 22. Since the test end equipment on the upper pressure plate 41 is not obstructed, it is very convenient to replace it. However, the test end equipment on the test base 3 is located in the chassis 1, and it can also be quickly replaced by rotating the upper cover 22 to open it.

[0021] A better solution is that the test base 3 is embedded in the box-shaped structure of the test platform 2, the front end of the test base 3 overlaps the surface of the upper cover 22, the rear end of the test base 3 is connected to the locking mechanism, and a set of lifting handles 34 are provided on the surface of the test base 3. The locking mechanism includes a toggle clamp 61, a shaft 62 connected to the toggle clamp 61, a bracket 63 at the other end of the shaft 62, a set of guide shafts 24 inside the upper cover 22, the bracket 63 passing through the guide shafts 24, and a locking plate 64 at the other end of the bracket 63. The locking plate 64 is connected to the side of the test base 3 via several connector blocks. When replacing the test end device, simply pull the shaft clamp 61, which pulls the shaft 62 backward, thereby moving the bracket 63 backward. This separates the connector blocks on the locking plate 64 from those on the test base 3, allowing the test base 3 to be pulled out by lifting the handle. In this embodiment, the test base 3 is designed as a modular structure, eliminating the need to replace the test end device separately. The test base 3 can be completely removed for replacement, and then the locking mechanism completes the locking and electrical connection.

[0022] Specifically, the upper cover 22 is equipped with an emergency stop button and function buttons.

[0023] The chassis 1 houses an electrical control box that controls the entire device. A drawer 11 is located on the front of the chassis 1, containing a keyboard for modifying test parameters. Before starting the test, the operator sets the various test parameters via the keyboard. Once the robotic arm is loaded, automatic testing can begin. The testing personnel can remain away from the testing area, resulting in higher safety.

[0024] Specifically, the top surface of the chassis 1 is also provided with a tri-color light 12 for issuing alarms according to the test structure, and a display 13 for displaying test parameters and results.

[0025] Specifically, the back of the chassis 1 is equipped with the same cooling fan 14 as the inside of the chassis 1.

[0026] Preferably, the bottom surface of the chassis 1 is provided with casters 15.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
