[0002] Digital voltage regulators are used to adjust DC voltage. Through digital signal processing technology, the voltage can be precisely controlled. They are used in many fields such as laboratories, industrial control, power electronics, medical equipment, etc. They can help users accurately adjust DC voltage to meet various needs.

[0003] Before leaving the factory, the digital voltage regulator needs to be tested to ensure that the performance is qualified. When testing a digital voltage regulator (such as the product HVR1000), the usual method is: the test wiring personnel make and process the test line according to the external terminals of the digital voltage regulator. During the test process, the test operator usually manually plugs and unplugs the test line terminals from the product and the test instrument. After the test line is connected, the digital voltage regulator is tested. It should be noted that such a conventional manual testing method, due to the large number of product terminals, requires a large number of product test lines to be connected. The manual plugging and unplugging operation of the test operator is cumbersome, and it is easy to have terminal connection problems such as wrong plugging, missing plugging, and loose plugging, resulting in a high test error rate and low test efficiency.

[0004] In addition, during the testing of the digital voltage regulator, there may be a risk of explosion of electronic components in the circuit board. The conventional manual testing method has no safety protection devices, which will cause personal safety hazards to the test operators.

[0025] The technical solution of the utility model is further described in detail below through specific implementation methods.

[0026] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances. This is merely a way of distinguishing objects with the same attributes when describing the embodiments of the present application.

[0027] Example 1

[0028] This embodiment provides a specific embodiment of a test auxiliary device for digital voltage regulator, such as Figure 1 As shown, the test auxiliary device for the digital voltage regulator includes a supporting base plate 1, two probe shifting mechanisms arranged on the supporting base plate 1, and a product supporting structure 5 arranged between the two probe shifting mechanisms; the probe shifting mechanism includes a lifting assembly and a probe assembly, the probe assembly includes a probe adapter plate and a probe, one side of the probe adapter plate is connected to the lifting assembly, and the other side of the probe adapter plate is connected to the probe; the product supporting structure 5 is located below the probe assembly, and is used to support and limit the product 14 to be tested.

[0029] It should be noted that the two probe shifting mechanisms have the same structure, wherein one probe shifting mechanism includes a first lifting assembly and a first probe assembly 7 , and the other probe shifting mechanism includes a second lifting assembly and a second probe assembly 8 .

[0030] It should also be noted that before the product to be tested 14 is placed on the product support structure 5, the lifting assembly drives the probe away from the product to be tested. After the product to be tested 14 is placed on the product support structure 5, the lifting assembly drives the probe close to the product to be tested, so that the product to be tested and the probe are quickly matched and pressed together, thereby replacing the manual work of plugging and unplugging test lines, avoiding terminal connection problems such as wrong plugging, missed plugging, and loose plugging during manual operation. The entire testing process frees the hands of the test operator and greatly improves the convenience of operation.

[0031] It should also be noted that, as Figure 3 As shown, the product support structure 5 is provided with a product limiting groove that matches the shape and size of the product to be tested 14. Before the test, the test operator pushes the product horizontally from front to back to limit the position, and then presses the product to be tested 14 down into the limiting groove for subsequent testing, which can prevent the product to be tested 14 from shaking during the test.

[0032] It should also be noted that, as Figure 3 It is shown that one side of the product support structure 5 is also provided with an opening for easy access to the product 14 to be tested, and the opening is arranged toward the product pick-up and drop-up port of the entire device.

[0033] In some embodiments, as shown in the attached Figure 2 As shown, the two lifting assemblies have the same structure, both including a cylinder 9, a pipe joint 13 connected to the cylinder 9, and a solenoid valve 10 arranged between the pipe joint 13 and the air inlet of the cylinder 9, and the solenoid valve 10 is installed on the supporting base plate 1 through a solenoid valve fixing seat 11.

[0034] It should be noted that the moving end of the cylinder 9 (the end portion of the cylinder piston rod) is connected to the probe through the probe adapter plate, and then the probe is driven to move up and down through the probe adapter plate. Therefore, the lifting assembly of this embodiment presses the terminal seat of the product to be tested 14 through the cylinder and the probe, and the compression accuracy is high, which can improve the accuracy and efficiency of the test.

[0035] Specifically, the cylinder 9 is an ultra-thin cylinder with a guide rod, such as TACQ20X30S, etc. It should be noted that the ultra-thin cylinder with a guide rod has a compact structure and light weight, can effectively save installation space, can make the entire device structure more compact, and is conducive to miniaturization; in addition, the ultra-thin cylinder with a guide rod has a self-guided function, which helps to achieve accurate docking between the probe and the product 14 to be tested.

[0036] It should also be noted that the external air pipe circuit is sealed and connected to the air inlet of the cylinder 9 through the pipe joint 13 and the solenoid valve 10; Figure 3 and attached Figure 4As shown, when testing is required, the air pipe circuit is connected, the cylinder 9 works to adjust the probe adapter plate and the probe 801 to the first position (the probe rises to the initial highest state), and then the product 14 to be tested is pushed horizontally from front to back into the limiting groove of the product support structure 5 of the device; as shown in the attached Figure 5 As shown, the solenoid valve 10 is turned on and the cylinders of the two probe shifting mechanisms work simultaneously, driving the probe adapter plate and the probe 801 to contact and press down on the upper plates of the terminal seats on both sides of the product to be tested 14. After the downward contact, the probes on the probe adapter plate are fully compressed and contacted with the terminal seats of the product to be tested 14, which is convenient for subsequent signal transmission.

[0037] It should also be noted that after the test process is completed, the solenoid valve 10 is controlled to work, and the solenoid valve 10 controls the cylinders of the two probe shifting mechanisms to make the probes quickly rise to the first position and then stop. Then the test operator takes out the test product and the test process is completed.

[0038] In some embodiments, as shown in the attached Figure 2 As shown, the test auxiliary device for the digital voltage regulator further includes a muffler 12 , and the muffler 12 is arranged at the exhaust port of the solenoid valve 10 .

[0039] Specifically, the model of the solenoid valve 10 may be 4V210-08B, and the model of the muffler 12 may be BLS01.

[0040] It should be noted that, in this embodiment, a muffler 12 is provided in the device to reduce the noise during the voltage regulator test.

[0042] Based on Example 1, this example provides another specific implementation of a test auxiliary device for a digital voltage regulator.

[0043] In some embodiments, the test auxiliary device for the digital voltage regulator further includes two protective shells 2 for respectively installing corresponding lifting components.

[0044] It should be noted that, as Figure 1 To Attachment Figure 7 As shown, two protective shells 2 are provided corresponding to the two probe shifting mechanisms to respectively protect the corresponding lifting component parts to prevent dust and the like from entering, thereby increasing the service life of the device.

[0045] It should also be noted that the two protective shells 2 are fixed on the support base plate 1, and the product support structure 5 is located between the two protective shells 2; Figure 1 To Attachment Figure 7As shown, a rear panel is further provided between the two protective shells 2, the upper portion of the rear panel is provided with a concave structure for facilitating the passage of the test line, and the lower portion of the rear panel is provided with a through hole for access to an external air pipe.

[0046] In some embodiments, the test auxiliary device for the digital voltage regulator further includes a protective cover plate 3, wherein the protective cover plate 3 is hingedly connected to one of the protective housings 2 via a hinge 4. Figure 6 shown.

[0047] It should be noted that in order to eliminate the personal safety hazard to the test operators, this embodiment adds a protective cover plate 3 to the device. During the test, the protective cover plate 3 on the top of the device is fully closed to ensure the safety of the test and play a role in safety protection.

[0048] In some embodiments, the protective cover plate 3 is made of a transparent material. Specifically, the protective cover plate 3 is made of a fully transparent thickened acrylic and is fixedly installed by a hinge 4, so that the test operator can look down and observe the test process. At the same time, the rotating structure is designed to facilitate the test operator to check the test status of the product.

[0049] In some embodiments, the test auxiliary device for the digital voltage regulator also includes a limit pin, and the support base plate 1 is provided with a guide hole 101 matching the limit pin. It should be noted that before the test, the test auxiliary device for the digital voltage regulator is first installed and fixed on the corresponding test bench from top to bottom through the guide hole 101 of the positioning pin 15, the test line is connected to the test bench, the test bench is ventilated to provide the air source required for the cylinder to work for the test auxiliary device for the digital voltage regulator, and the test bench is powered on to provide the power required for the solenoid valve 10 to work for the test auxiliary device for the digital voltage regulator.

[0050] In some embodiments, as shown in the attached Figures 1 to 7 As shown, a test button 6 is also provided on the protective shell 2, and the test button 6 is used to control the operation of the solenoid valve 10. The test button 6 and the solenoid valve 10 are respectively connected to the controller. The specific circuit structure is the existing technology and will not be repeated here.

[0051] It should be noted that after placing the product 14 to be tested, the product 14 to be tested and the probe can be quickly matched and pressed by pressing the test button 6, which is very convenient and quick to operate. Therefore, the test device is easy and quick to operate, and meets the test fixation requirements of the existing production line test bench for the test product.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
