Description

Technical Field

[0001] This application relates to the field of testing equipment technology, and in particular to an interpolation testing device. Background Technology

[0002] An inverter is a power electronic device that converts direct current (DC) into alternating current (AC). It is widely used in solar power generation, electric vehicles, UPS power supplies, and home emergency power supply. It can output AC power of different qualities, such as pure sine waves, modified waves, or square waves, to meet the needs of various electrical appliances. It also features voltage regulation, frequency stabilization, and overload protection, making it a key component of renewable energy systems and off-grid power consumption.

[0003] In the manufacturing process of inverters, the testing stage is crucial, directly affecting the product's performance stability and reliability. Currently, the industry commonly uses manual or semi-automated testing methods. Manual or semi-automated interlocking methods struggle to ensure precise alignment of the test interfaces, leading to unstable contact resistance. If the interface is not accurately positioned and inserted directly, it can easily damage the inverter's interfaces.

[0004] Therefore, there is an urgent need for a high-efficiency, high-precision interlocking test device to improve the efficiency and reliability of inverter testing. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a mating test device, which solves the technical problem that manual or semi-automatic mating methods cannot guarantee the accurate connection of the test interface, and that directly inserting the interface can easily lead to damage to the inverter interface.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A mating test device includes: a frame for supporting the mating test device; a mating plate mounted on the frame and having an interface for mating with a device under test (DUT); a conveying assembly mounted on the frame for conveying the DUT towards one side of the mating plate; a driving assembly mounted on the frame for driving the mating plate to move towards the DUT; and a protective assembly mounted on the frame for protecting the DUT.

[0008] Furthermore, the conveying assembly includes a driving wheel and a driven wheel, which are rotatably mounted on the frame. A drive motor is mounted on the frame, and the output shaft of the drive motor is connected to the driving wheel. A conveying chain is provided on the driving wheel and the driven wheel, and the conveying chain is sleeved on the driving wheel and the driven wheel in a closed loop.

[0009] Furthermore, a support plate is provided on the frame, and a docking cylinder is installed on the support plate, with the piston rod of the docking cylinder connected to the docking plate.

[0010] Furthermore, a guide rod is provided on the docking plate. One end of the guide rod is connected to the docking plate, and the other end passes through the support plate. A mounting plate is provided at the end of the guide rod that passes through the support plate. A contact sensor is provided on the mounting plate, and the contact sensor faces the side closer to the support plate.

[0011] Furthermore, the protective assembly includes a lifting cylinder, which is vertically installed on the side of the frame near the docking plate. A pin is provided on the piston rod of the lifting cylinder, the pin is vertically arranged, and one end of the pin is connected to the piston rod of the lifting cylinder.

[0012] Furthermore, a lifting plate is provided on the frame, one end of the lifting plate is mounted on the frame, and the other end extends horizontally towards the side of the conveyor chain. A lifting sensor is provided on the lifting plate, and the lifting sensor faces towards the inside of the frame.

[0013] Furthermore, the frame has a guide plate on one side near the conveyor chain, and the guide plate is parallel to the conveying direction of the conveyor chain.

[0014] In summary, this application includes at least one of the following beneficial technical effects of the interpolation testing device:

[0015] 1. In use, the device under test is placed on the rack. The conveying component transports the device under test to the side closer to the docking plate. Then, the drive component drives the docking plate to move closer to the device under test, so that the interface on the docking plate connects with the interface on the device under test. Before the interface on the docking plate connects with the device under test, the protection component protects the interface, which improves the accuracy of the device under test's position on the rack, reduces the risk of damage to the interface of the device under test when the interface is inserted, and improves the testing efficiency and reliability of the device under test.

[0016] 2. The stability of the interface of the device under test is improved by the contact sensor on one side of the guide rod and the lifting sensor on the lifting plate, preventing damage to the interface of the device under test during the insertion process;

[0017] 3. The testing efficiency of the device under test is improved by setting up docking cylinders and conveyor chains on the support plate. Attached Figure Description

[0022] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0024] This application discloses an interpolation testing device.

[0025] Reference Figures 1-2 A mating test device includes a frame 1, a mating plate 2 mounted on the frame 1, and an interface 21 mounted on the mating plate 2. In use, the device under test (DUT) is connected to the interface 21 on the mating plate 2. The frame 1 is equipped with a conveying assembly 3 and a driving assembly 4. The conveying assembly 3 conveys the DUT to one side of the mating plate 2, and the driving assembly 4 conveys the mating plate 2 towards the side closest to the DUT. The frame 1 is also equipped with a protective assembly 5, which protects the interface 21 of the DUT.

[0026] Reference Figure 2Two sets of conveying components 3 are spaced apart on the frame 1. In use, the two sides of the device under test are placed on the two sets of conveying components 3, which then convey the device. Each conveying component 3 includes a driving wheel 31 and a driven wheel 32, which are rotatably mounted on the frame 1. A conveyor chain 33 is provided between the driving wheel 31 and the driven wheel 32, forming a closed loop around them. In use, both ends of the device under test are placed on the conveyor chain 33. As the conveyor chain 33 rotates on the driving wheel 31 and the driven wheel 32, the device under test moves on the frame 1.

[0027] To improve the ease of rotation of the conveyor chain 33 on the frame 1, a rotating shaft 34 is provided on the frame 1, with both ends of the rotating shaft 34 connected to the drive wheels 31 on both sides. A drive motor 35 is provided on the frame 1 and is connected to the rotating shaft 34. In use, the drive motor 35 drives the rotating shaft 34 to rotate, and the rotating shaft 34 drives the drive wheels 31 to rotate. As the drive wheels 31 rotate, the conveyor chain 33 rotates on the frame 1.

[0028] Reference Figure 3 The drive assembly 4 includes a support plate 41, which is mounted on the frame 1. The docking plate 2 is rectangular in shape. Two guide rods 42 are provided on each side of the docking plate 2 along its length. One end of the guide rod 42 is connected to the docking plate 2, and the other end passes through the support plate 41. In use, the guide rod 42 slides and engages with the support plate 41, thereby improving the stability of the docking plate 2 sliding on the frame 1.

[0029] Furthermore, a docking cylinder 43 is provided on the support plate 41. The docking cylinder 43 is horizontally positioned. In use, the docking cylinder 43 is mounted on the support plate 41, and one end of the piston rod of the docking cylinder 43 is connected to the docking plate 2. During use, the docking cylinder 43 drives the docking plate 2 to slide on the frame 1. After the conveyor chain 33 transports the device under test to the side close to the docking plate, the docking cylinder 43 drives the interface 21 on the docking plate 2 to connect with the connector on the device under test.

[0030] Furthermore, a mounting plate 44 is provided at one end of the guide rod 42 that passes through the support plate 41, and the mounting plate 44 is mounted on the guide rod 42. A contact sensor 45 is provided on the mounting plate 44, with one end of the contact sensor 45 facing the side closer to the support plate 41. When the docking cylinder 43 drives the docking plate 2 to move closer to the device under test, the contact sensor 45 moves closer to the support plate 41. When the contact sensor 45 contacts the support plate 41, the docking cylinder 43 stops driving the docking plate 2 to move towards the device under test. This prevents the docking cylinder 43 from excessively moving the docking plate 2 closer to the device under test, thus protecting the connector. By adjusting the distance between the contact sensor 45 and the support plate 41, the movement distance of the docking plate 2 on the frame 1 can be controlled.

[0031] Guide plates 11 are provided on one side of the frame 1 near the two sets of conveyor chains 33. The guide plates 11 are rectangular in shape and their length direction is parallel to that of the conveyor chain 33. In use, the guide plates 11 guide the equipment under test, thereby improving the stability of the equipment under test sliding on the frame 1.

[0032] Furthermore, if the connector of the device under test (DUT) is misaligned with the interface 21 on the docking plate 2, and the docking cylinder 43 drives the docking plate 2 to move closer to the DUT, on the one hand, the connector on the DUT and the interface 21 on the docking plate 2 are prone to damage; on the other hand, during the docking process between the docking plate 2 and the DUT, the DUT is not fixed, which causes the docking plate 2 to push the DUT to move during the docking process, resulting in the interface 21 on the docking plate 2 not being able to be properly connected to the DUT, thus affecting the test accuracy of the DUT.

[0033] Reference Figure 2 The protective component 5 includes lifting cylinders 51. Two sets of lifting cylinders 51 are spaced apart on the frame 1. The two sets of lifting cylinders 51 are vertically arranged, and each set of lifting cylinders 51 is provided with a pin 52. The pin 52 is vertically arranged, and one end of the pin 52 is connected to the piston rod of the lifting cylinder 51, while the other end extends vertically away from the lifting cylinder 51.

[0034] In addition, a lifting plate 53 is provided on the frame 1. One end of the lifting plate 53 is connected to the frame 1, and the other end extends horizontally towards the side of the conveyor chain 33. Furthermore, a lifting sensor 54 is installed on the lifting plate 53, with the lifting sensor 54 facing the side of the device under test. In use, the bottom plate of the device under test moves between the conveyor chain 33 and the lifting plate 53.

[0035] In use, when the device under test (DUT) moves to the side closer to the docking plate 2, the lifting cylinder 51 drives the pin 52 to move towards the DUT. When the DUT is accurately positioned on the conveyor chain 33, the pin 52 can be inserted into the DUT, positioning it and improving the stability of the docking plate 2 when docking with the DUT. If the DUT's position is off, the pin 52 on the lifting cylinder 51 will lift the DUT. As the DUT is lifted, it will lift the lifting plate 53. After the lifting sensor 54 detects that the lifting plate 53 has been lifted, the docking cylinder 43 will not drive the docking plate 2 to move towards the DUT, thus preventing damage to the interface 21 on the docking plate 2 and the connector on the DUT.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
