The power-on testing device includes a first drive mechanism and a return current receiving contact mounted on the output end of the first drive mechanism. After the housing is placed at the loading station, the first transmission mechanism moves the housing from the loading station to the power-on testing station. Then, the second transmission mechanism moves the connector to the insertion position, and the telescopic mechanism drives the connector to connect with the housing. The first drive mechanism of the power-on testing device then drives the return current receiving contact to abut against the housing. Since both the connector and the return current receiving contact are connected to the safety testing instrument, the connection between the safety testing instrument and the housing under test can be achieved through the connection of the connector and the abutment of the return current receiving contact, thus enabling safety testing of the housing. After testing, the telescopic mechanism can move the connector away from the housing, and then the first transmission mechanism moves the housing to the unloading station. This invention enables automatic safety testing of the housing, eliminating the need for manual connection and testing, reducing the risk of electric shock, lowering testing risks, and improving testing efficiency.

[0032] To explain in detail the technical content, structural features, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0033] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0034] Please see Figures 1 to 6 This utility model discloses a safety testing device 1 for testing the housing (not shown) of an LED display screen. It includes a machine base 10, a first transmission mechanism 20, a power supply device 30, and a power supply testing device 40. The machine base 10 includes an electrical control box 11 and a mounting platform 12 mounted on the electrical control box 11. The electrical control box 11 houses a safety testing instrument (not shown). The mounting platform 12 has a loading station 13, a power supply testing station 14, and a unloading station 15 arranged sequentially along the X-axis. The first transmission mechanism 20 is mounted on the mounting platform 12 and is used to transport the housing along the X-axis, causing the housing to move between the loading station 13, the power supply testing station 14, and the unloading station 15. A power-on device 30 is installed at the power-on testing station 14 and includes a second transmission mechanism 31, a telescopic mechanism 32 installed at the output end of the second transmission mechanism 31, and a connector 33 installed at the output end of the telescopic mechanism 32. The second transmission mechanism 31 is used to move the connector 33 to the insertion position, and the telescopic mechanism 32 is used to drive the connector 33 to extend or retract to insert into or leave the housing. The connector 33 is configured to be electrically connected to the safety testing instrument. A power-on testing device 40 is installed at the power-on testing station 14 and includes a first drive mechanism 41 and a return current receiving contact 42 installed at the output end of the first drive mechanism 41. The first drive mechanism 41 is used to drive the return current receiving contact 42 to abut against the housing, and the return current receiving contact 42 is configured to be electrically connected to the safety testing instrument.

[0035] In this embodiment of the utility model, the machine base 10 includes an electrical control box 11 with a built-in safety testing instrument and a mounting platform 12 mounted on the electrical control box 11. The mounting platform 12 is provided with a first transmission mechanism 20 for driving the box to move along the X-axis direction, a power supply device 30 and a power supply testing device 40 set at the power supply testing station 14. The power supply device 30 includes a second transmission mechanism 31, a telescopic mechanism 32 and a connector 33 installed at the output end of the telescopic mechanism 32. The power supply testing device 40 includes a first drive mechanism 41 and a return current receiving contact 42 installed at the output end of the first drive mechanism 41. After the enclosure is placed at the loading station 13, it is moved from the loading station 13 to the power-on testing station 14 by the first transmission mechanism 20. Then, the second transmission mechanism 31 drives the connector 33 to the insertion position, and the telescopic mechanism 32 drives the connector 33 to connect with the enclosure (i.e., to the power cord interface of the enclosure). Finally, the first drive mechanism 41 of the power-on testing device 40 drives the return current receiving contact 42 to abut against the enclosure. Since both the connector 33 and the return current receiving contact 42 are connected to the safety testing instrument, the connection between the safety testing instrument and the enclosure under test can be achieved through the connection of the connector 33 and the abutment of the return current receiving contact 42, so as to perform the test on the enclosure. After the test is completed, the telescopic mechanism 32 can drive the connector 33 to leave the enclosure, and then the first transmission mechanism 20 moves the enclosure to the unloading station 15. This invention enables automatic safety testing of the enclosure, eliminating the need for manual connection and testing, reducing the risk of electric shock, lowering testing risks, and improving testing efficiency.

[0036] Specifically, connector 33 is connected to the safety testing instrument via an output line, and return receiving contact 42 is connected to the safety testing instrument via a return line.

[0037] The output lines connected to connector 33 include a grounding output line and a withstand voltage output line. The return lines connected to return current receiving contact 42 include a grounding return line and a withstand voltage return line. After connector 33 and return current receiving contact 42 are both connected to the enclosure, the enclosure will release a start signal to the safety testing instrument.

[0038] It should be understood that in actual operation, the loading station 13 can also be used as the unloading station, and correspondingly, the unloading station 15 can be used as the loading station. In this case, the first transmission mechanism 20 can reverse the transmission of the box. Alternatively, either the loading station 13 or the unloading station 15 can be used as the loading or unloading station. After the box completes the test at the power-on detection station 14, the first transmission mechanism 20 reverses the transmission of the box to the loading station for unloading. In this case, only one operator is needed to complete the loading and unloading operations.

[0039] Specifically, the first transmission mechanism 20 includes a first conveyor belt 21 and a second conveyor belt 22 arranged side by side and spaced apart, with the two ends of the housing respectively placed on the first conveyor belt 21 and the second conveyor belt 22. Of course, the first transmission mechanism 20 is not limited to a conveyor belt.

[0040] Please see Figure 3 In some embodiments, the second transmission mechanism 31 includes an X-axis transmission assembly 311, a Y-axis transmission assembly 312, and a Z-axis transmission assembly 313. The Y-axis transmission assembly 312 is mounted on the mounting platform 12, and the Z-axis transmission assembly 313 is mounted on the Y-axis transmission assembly 312. A telescopic mechanism 32 is mounted on the Z-axis transmission assembly 313. The Z-axis transmission assembly 313 drives the telescopic mechanism 32 to move along the Z-axis direction, the X-axis transmission assembly 311 drives the Z-axis transmission assembly 313 to move along the X-axis direction, and the Y-axis transmission assembly 312 drives the X-axis transmission assembly 311 to move along the Y-axis direction. Through the coordinated arrangement of the X-axis transmission assembly 311, the Y-axis transmission assembly, and the Z-axis transmission assembly 313, the connector 33 can move flexibly, achieving precise three-dimensional spatial positioning. This ensures that the connector 33 accurately reaches the target position for docking with the housing, improving operational accuracy and efficiency.

[0041] Specifically, the second transmission mechanism 31 further includes two mounting brackets 314 spanning the mounting platform 12 along the Y-axis direction, with the two mounting brackets 314 spaced apart along the X-axis direction. The first transmission mechanism 20 is located below the mounting brackets 314. The Y-axis transmission assembly 312 includes two Y-axis linear modules respectively mounted on the two mounting brackets 314. The X-axis transmission assembly 311 includes X-axis linear modules mounted on the sliders of the two Y-axis linear modules. The Z-axis transmission assembly 313 is mounted on the slider of the X-axis linear module. Since the two mounting brackets 314 span the mounting platform 12, and each transmission assembly is mounted on the two mounting brackets 314, with the first transmission mechanism 20 located below the mounting brackets 314, installation space is saved without affecting the transmission of the housing by the first transmission mechanism 20.

[0042] Specifically, the Z-axis transmission assembly 313 is a linear module, and the telescopic mechanism 32 is mounted on the slider of the linear module.

[0043] Of course, the X-axis transmission assembly 311, Y-axis transmission assembly 312, and Z-axis transmission assembly 313 are not limited to linear modules.

[0044] Please see Figure 3 and Figure 4In some embodiments, a visual positioning device 34 is also installed at the output end of the second transmission mechanism 31. The visual positioning device 34 is used for visual positioning of the box. The second transmission mechanism 31 can drive the visual positioning device 34, the telescopic mechanism 32, and the connector 33 to move together. Through the visual positioning device 34, it is possible to detect whether the box has moved into place to determine whether it can be connected to the box for the next detection operation. In a specific example, the visual positioning device 34 is set as a camera. Of course, the visual positioning device 34 is not limited to this.

[0045] In some embodiments, the output end of the second transmission mechanism 31 is also equipped with a barcode scanner 35, which is used to scan the identification code on the enclosure. By scanning the identification code on the enclosure, the enclosure being tested can be bound to it, so that subsequent measurement information can be associated with the enclosure and uploaded to the MES system.

[0046] Specifically, the identification code can be a QR code or a barcode.

[0047] In some embodiments, the second transmission mechanism 31 includes a Z-axis linear module, i.e., the Z-axis transmission assembly 313 is a linear module. A vertically arranged first bracket 36 is mounted on the slider of the Z-axis linear module, and a second bracket 37 is mounted on the bottom of the first bracket 36. A telescopic mechanism 32 is mounted on the second bracket 37. A wire-passing structure 38 is connected above the connector 33 to the first bracket 36. The wire-passing structure 38 forms a wire-passing hole 381, which is used for the output wire connected to the connector 33 to pass through. The wire-passing structure 38 optimizes the wiring, ensuring smooth and interference-free connection.

[0048] Specifically, the second bracket 37 includes a horizontal plate 370 installed at the bottom of the first bracket 36 and a first side plate 371 and a second side plate 372 connected on both sides of the horizontal plate 370 in the X-axis direction. The visual positioning device 34 is installed on the side of the first side plate 371 away from the second side plate 372.

[0049] The connector 33 includes a first set of connectors 331 and a second set of connectors 332. The telescopic mechanism 32 includes a first telescopic mechanism 321 and a second telescopic mechanism 322. The first set of connectors 331 is installed at the output end of the first telescopic mechanism 321, and the second set of connectors 332 is installed at the output end of the second telescopic mechanism 322. The first telescopic mechanism 321 and the second telescopic mechanism 322 are respectively installed on opposite sides of the second side plate 372. In a specific example, the first set of connectors 331 and the second set of connectors 332 are of different models. By setting different models of connectors 33, it is possible to adapt to enclosures with different interface models, thereby enhancing the versatility of the equipment.

[0050] Specifically, the first telescopic mechanism 321 and the second telescopic mechanism 322 can be cylinders. Of course, this is not a limitation.

[0051] Please see Figure 5 In some embodiments, the first drive mechanism 41 includes a Z-axis drive cylinder 411 and an X-axis drive cylinder 412. The X-axis drive cylinder 412 is installed at the output end of the Z-axis drive cylinder 411, and a contact mounting bracket 43 is installed at the output end of the X-axis drive cylinder 412. The return receiving contact 42 is installed on the contact mounting bracket 43.

[0052] In this specific example, there are two return flow receiving contacts 42. Of course, this is not a limitation.

[0053] Please see Figure 1 and Figure 2 In some embodiments, the safety testing equipment 1 further includes a lifting mechanism 50, which is configured corresponding to the power-on testing station 14. The lifting mechanism 50 is used to lift the housing conveyed to the power-on testing station 14 to the testing height. When the housing enters the housing power-on testing station 14, the lifting mechanism 50 lifts the housing to move it away from the first conveying mechanism 20, and after testing, the housing falls back onto the first conveying mechanism 20.

[0054] Specifically, the lifting mechanism 50 is located between the first conveyor belt 21 and the second conveyor belt 22, and the driver of the lifting mechanism 50 (not shown) is located inside the electrical control box 11. The output end of the driver extends above the mounting platform 12 and is connected to a lifting plate 51, which is used to lift the box.

[0055] Specifically, the lifting mechanism 50 also includes a limiting block 52 connected to one side of the lifting plate 51 in the X-axis direction, and the return receiving contact 42 is located on the side of the lifting plate 51 away from the limiting block 52 in the X-axis direction.

[0056] Please see Figure 6 In some embodiments, the safety testing equipment 1 further includes a positioning component 60 disposed at the power-on testing station 14. The positioning component 60 includes a positioning cylinder 61 and a positioning block 62. The positioning block 62 is installed at the output end of the positioning cylinder 61. The positioning cylinder 61 is used to drive the positioning block 62 to move in the Y-axis direction. The positioning cylinder 61 pushes the positioning block 62, and the positioning block 62 pushes the housing to perform Y-axis positioning of the housing. The Z-axis drive cylinder 411 lifts the X-axis drive cylinder 412, and the X-axis drive cylinder 412 pushes toward the limiting block 52 so that the housing abuts between the return receiving contact 42 and the limiting block 52.

[0057] By using the positioning cylinder 61 to drive the positioning block 62 to precisely adjust the position of the housing in the Y-axis direction, and the power-on detection device 40 and the limit block 52 to position the housing in the X-axis direction, the test position of the housing can be limited, thus achieving accurate positioning of the housing and ensuring accurate docking of the connector 33 and the return current receiving contact 42 with the housing.

[0058] Specifically, a switch button 70 for controlling the operation of the safety testing equipment 1 is provided on one side of the mounting platform 12. The operation of the safety testing equipment 1 can be controlled by the switch button 70.

[0059] Specifically, the safety testing equipment 1 is also equipped with a three-color warning light (not shown in the figure) to facilitate the indication of test results.

[0060] To facilitate understanding of this utility model, the operation process of the device in the accompanying drawings is briefly described below, which should not be regarded as a limitation of this utility model.

[0061] The operator places the housing at the loading station 13 and starts the equipment via the switch button 70. After the housing is conveyed from the loading station 13 to the power-on testing station 14 via the first transmission mechanism 20, the lifting mechanism 50 raises the housing, adjusting its test position via the limit block 52, the alignment component 60, and the power-on testing device 40. The second transmission mechanism 31 moves the first support 36 and the second support 37, the visual positioning device 34 identifies whether the housing is in position, and the barcode scanning device 35 identifies the identification code on the housing. Once the housing is confirmed to be in position and the housing information matches, the telescopic mechanism 32 drives the first set of connectors 321 or the second set of connectors 322 to connect with the housing. Since the return current receiving contact 42 abuts against the housing and the plug 33 connects with the housing, the test connection between the housing and the safety testing instrument is achieved. The safety testing instrument begins to acquire test data and performs safety testing on the housing. During the safety testing process, if the test is passed, the green light of the three-color warning light will illuminate to indicate that the test has passed; if the test fails, the red light of the three-color warning light will illuminate to indicate that the test is abnormal. The test results are saved and uploaded to the MES. After the test is completed, the lifting mechanism 50 lowers the box, causing it to return to the first transmission mechanism 20. The first transmission mechanism 20 then moves the box back to the unloading station 15, where the operator unloads the tested box from the unloading station 15.

[0062] The above-disclosed examples are merely preferred embodiments of the present utility model, intended to facilitate understanding and implementation by those skilled in the art. They should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the scope of the present utility model patent shall still fall within the scope of the present utility model.
