Description

Technical Field

[0001] The present invention relates to the technical field of aging test devices, and more particularly to a micro-inverter aging test device. Background Art

[0002] In the production process of inverters, aging test is the most critical quality control link. However, the aging test process usually takes a long time, and the test steps are cumbersome, requiring a high level of technical proficiency and skill from the test personnel. Especially when frequently switching the test process for different models, the complexity of the operation further increases.

[0003] During the implementation of the inverter aging test, the product needs to be transported from the assembly line to the aging room, and then cable connections and various switch operations are carried out to meet the requirements of the test environment. In this process, the turnover of the product increases the time and site requirements. At the same time, human errors may occur when operating the cables and switches, bringing electrical risks and even potential safety hazards to personnel and property.

[0004] Chinese Patent CN112098754B discloses an electronic component aging test socket and its aging test device. The electronic component has an input end and an output end. The aging test socket includes: a base, a mounting seat slidably mounted on the base, a test output docking seat connected to the base, a first telescopic mechanism connected to the mounting seat, a test input docking seat mounted opposite to the test output docking seat, and a second telescopic mechanism connected to the test input docking seat. This patent enables the mounting seat and the test seat to be electrically connected through the slidably arranged mounting seat. However, during the connection process, there are situations where alignment cannot be achieved during docking, and the connection is not in place and unstable.

[0005] In addition, Chinese Patent Application CN112881898A discloses an integrated circuit high-temperature aging test device, including a box body and an aging motherboard inside the box body. The aging daughter board is installed on the motherboard through a station slot, and the fixing block is firmly inserted on the support rod through the cooperation of rubber teeth, positioning tooth grooves and magnetic sheets, so as to realize the limit fixation of the telescopic movement positions of the sliding sleeve and the positioning block, ensure accurate positioning of the positioning block, stable pressing effect, improve the operation convenience and stability during detection, reduce the error caused by poor contact, and improve the detection accuracy and quality. However, the structure of this device is relatively large and it is difficult to be directly used on the test socket of an inverter. Although the use of a pressing structure can improve the connection stability, due to its large volume, it is not suitable for installation on the test socket of an inverter. Therefore, in the aging test of inverters, a more compact and stable design solution still needs to be sought to reduce manual operation and improve the test efficiency and safety.

[0016] The beneficial effects of the present invention compared with the prior art are as follows:

[0017] 1.

Through the design of the bevel edge, the driving part can move smoothly, reducing the errors caused by unstable movement.

[0032] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be described in further detail below in conjunction with the drawings and specific implementation modes.

[0033] As Figures 1 to 5 shown: 1. A micro-inverter 4 aging test device, including a test seat 1 and a mounting seat 2 that can slide towards the test seat 1. It is characterized in that one end of the mounting seat 2 close to the test seat 1 is provided with a mounting plate 21 electrically connected to the inverter 4, and a plurality of slots 211 for aging test are provided on one side of the mounting plate 21 close to the test seat 1; a connector 11 matching the slots 211 on the mounting plate 21 is provided on the test seat 1; driving assemblies 3 for driving the mounting plate 21 to slide along the width direction of the test seat 1 are provided at both ends of the test seat 1 in the length direction; the driving assembly 3 includes two clamping arms 31 that can rotate relative to each other, the two clamping arms 31 are in a mirror-symmetrical state, and both clamping arms 31 are L-shaped structures; two first pulleys 32 are provided at both ends of the mounting plate 21 in the length direction, and the two first pulleys 32 are respectively in sliding fit with the two clamping arms 31; when the mounting plate 21 contacts the test seat 1, through the relative rotation of the two clamping arms 31, the two clamping arms 31 respectively contact the two first pulleys 32 and drive the first pulleys 32 to slide along the inner side of the clamping arms 31, thereby driving the mounting plate 21 to move towards the test seat 1.

[0034] First, place the inverter 4 on the mounting base 2 and electrically connect the inverter 4 to the mounting plate 21. At this time, drive the mounting base 2 to move towards the test base 1 through a sliding device (such as a conveyor belt or a rail car), thereby driving the movement of the mounting plate 21 until the slot 211 on the mounting plate 21 can contact the connector 11 on the test base 1. When the mounting plate 21 contacts the test base 1, the sliding device stops, and at this time, the driving assembly 3 starts to work. The relative rotation of the two clamping arms 31 of the driving assembly 3 contacts the two first pulleys 32 on the mounting plate 21. Since the two clamping arms 31 are arranged in mirror symmetry and the clamping arm 31 is an L-shaped structure, after the first pulley 32 contacts the clamping arm 31, the rotation of the clamping arm 31 can drive the first pulley 32 to slide along the inner side of the clamping arm 31. The first pulley 32 drives the movement of the mounting plate 21, causing the mounting base 2 to move towards the test base 1, ensuring that the slot 211 and the connector 11 can be stably inserted, thereby realizing the aging test of the inverter 4.

[0035] The cooperation between the first pulley 32 and the clamping arm 31 provides a smooth driving method, enabling the slot 211 on the mounting plate 21 to be stably connected to the connector 11 on the test base 1, avoiding the problem of unstable contact caused by possible vibrations when the traditional sliding device drives the mounting base 2 to contact the test base 1. It helps to precisely control the sliding direction and speed of the mounting plate 21, thereby ensuring the accuracy and reliability of the test results during the aging test. Through precise insertion and a stable driving mechanism, it is ensured that the electrical connection of the micro-inverter 4 is not disturbed during the aging test, thereby improving the reliability of the test and the credibility of the data, and avoiding test errors caused by poor insertion.

[0036] As Figures 2 to 7 shown: The driving assembly 3 further includes a driving member 33 and two connecting rods 311. The driving member 33 is arranged on the test base 1 so as to be able to slide along the width direction of the test base 1. The two connecting rods 311 are respectively located beside the two clamping arms 31. One end of each of the two connecting rods 311 is hinged to the driving member 33, and the other ends of the two connecting rods 311 are respectively hinged to the middle parts of the two clamping arms 31.

[0037] By moving the driving member 33, the driving member 33 slides along the width direction of the test base 1, which can drive the two connecting rods 311 hinged thereto. Since the two clamping arms 31 are relatively rotatably arranged beside the two connecting rods 311, the movement of the connecting rods 311 can drive the two clamping arms 31 to rotate around their connection points with the test base 1. When the driving member 33 moves away from the mounting plate 21, the two clamping arms 31 approach each other. When the driving member 33 approaches the mounting plate 21, the two clamping arms 31 move away from each other. In the initial state, the two clamping arms 31 are in a state of moving away from each other. By the approach of the mounting plate 21, the driving member 33 slides on the test base 1 towards the side away from the mounting plate 21, thereby driving the two clamping arms 31 to approach each other, so as to clamp the two first pulleys 32 on the mounting plate 21, enabling the first pulleys 32 to slide along the inner sides of the clamping arms 31. Through the movement of the first pulleys 32, the mounting plate 21 gradually approaches the test base 1, ensuring that the slot 211 on the mounting plate 21 and the connector 11 on the test base 1 can be stably and accurately docked, and completing the aging test of the inverter 4.

[0038] Through the coordinated action of the driving member 33 and the connecting rod 311, the rotation of the clamping arm 31 and the sliding of the first pulley 32 can be precisely controlled, enabling the mounting plate 21 and the test base 1 to be stably and accurately docked, significantly improving the contact stability during the test process, and avoiding the influence of the insertion error on the aging test results. The driving member 33 drives the connecting rod 311 through sliding to realize the rotation of the clamping arm 31, which has high flexibility and adjustability. This design can adjust the position of the clamping arm 31 by adjusting the position of the driving member 33 according to different operation requirements, effectively ensuring the precise docking of the device during the test process. Compared with the traditional complex driving system, this device adopts a simple combination of the connecting rod 311 and the clamping arm 31, with a compact and efficient structure. Through the sliding control of the driving member 33, the rotation of the clamping arm 31 and the movement of the first pulley 32 are realized, which not only simplifies the design of the device but also improves the working efficiency of the device. This device can ensure that each insertion during the aging test of the inverter 4 can be stable, avoiding the test data error caused by poor insertion, improving the accuracy and reliability of the test, and ensuring the repeatability and credibility of the test results.

[0039] As Figures 2 to 7 shown: Conical transmission members 212 are provided at both ends of the mounting plate 21 in the length direction. The axes of the transmission members 212 are horizontally arranged. The diameter of the transmission members 212 on the side away from the mounting plate 21 is smaller than the diameter on the side close to the mounting plate 21. An installation sleeve 12 that matches the transmission member 212 is provided at one end of the driving member 33 close to the mounting plate 21. When the mounting plate 21 contacts the test base 1, the transmission member 212 can be inserted into the installation sleeve 12 and drive the driving member 33 to move.

[0040] When the slot 211 on the mounting plate 21 is docked with the connector 11 of the test seat 1 driven by the sliding device, there will still be a problem of inaccurate docking, which will affect the subsequent driving of the mounting plate 21 by the driving component 3. By arranging conical transmission parts 212 at both ends of the mounting plate 21, the transmission parts 212 can match with the mounting sleeve 12 on the driving part 33, and accurately insert into the mounting sleeve 12 when the mounting plate 21 contacts the test seat 1, and drive the driving part 33 to move a small distance, thus ensuring the precise control of the driving component 3, reducing the error caused by unstable plugging, and improving the stability during the test.

[0041] Due to the conical structure of the transmission part 212, the gradually changing diameter on the transmission part 212 can ensure the formation of a uniform contact surface when inserting into the mounting sleeve 12, thus realizing a more stable and precise power transmission. In this way, the driving part 33 can move smoothly and without clearance, thus avoiding the vibration problems that may occur in the traditional system, ensuring the stability of the plug-in while achieving precise docking. It avoids possible jamming and unnecessary friction, improves the smoothness of the driving process, reduces the wear or damage that may be caused by long-term use, and enhances the durability of the device.

[0042] As Figures 2 to 7 shown: The driving part 33 is provided with a slide rail 331 extending in the vertical direction and a hypotenuse 332 communicating with the slide rail 331. The driving component 3 further includes a transmission rod 34 arranged below the driving part 33. The transmission rod 34 is arranged in a vertical state and can slide along the height direction of the test seat 1. The top end of the transmission rod 34 is provided with a rotatable second pulley 341. When the transmission rod 34 slides along the height direction of the test seat 1, the transmission rod 34 can drive the second pulley 341 to slide along the hypotenuse 332 and the slide rail 331, thereby driving the driving part 33 to move.

[0043] By arranging a slide rail 331 extending in the vertical direction and a hypotenuse 332 communicating with the slide rail 331 on the driving part 33, combined with the cooperation of the transmission rod 34 and the second pulley 341, the device realizes stable and precise driving control. When the transmission rod 34 slides along the height direction of the test seat 1, the transmission rod 34 drives the second pulley 341 to first slide along the hypotenuse 332 on the driving part 33, and then the second pulley 341 slides into the slide rail 331. During this process, the driving part 33 is pushed to move along the width direction of the test seat 1. This design ensures the smooth movement of the driving part 33, reduces the error caused by unstable movement, and thus improves the accuracy of control.

[0044] When the second pulley 341 slides along the hypotenuse 332, it drives the driving member 33 to slide in the width direction of the test base 1. When the second pulley 341 slides into the slide rail 331, since the slide rail 331 extends in the vertical direction, the further movement of the driving member 33 is restricted. At this time, the clamping force of the clamping arm 31 on the first pulley 32 will stop accordingly, ensuring that no further pressure is applied after the slot 211 on the mounting plate 21 and the connector 11 on the test base 1 are plugged in place. Through this design, damage to the connector 11 caused by excessive pressure is avoided, and at the same time, a stable locking effect is provided, ensuring that the connection between the slot 211 and the connector 11 can remain stable during a long-term aging test. Since the aging test usually lasts for more than 4 hours, this locking method effectively guarantees the stable connection between the slot 211 and the connector 11 of the inverter 4 during the aging test, ensuring the accuracy and reliability during the test process.

[0045] The cooperation between the hypotenuse 332 and the slide rail 331 optimizes the power transmission path, reduces the resistance and unbalanced forces that may occur in the traditional drive system, and improves the working efficiency of the transmission system. This design avoids excessive friction and ensures efficient and stable power transmission. In addition, by integrating multiple functions into a few components, the structure of the drive system is simplified, the number of components is reduced, and the compactness and working efficiency of the device are improved. At the same time, the simplified design reduces the complexity of production and maintenance and lowers the cost.

[0046] As Figures 2 to 5 、 Figure 8 and Figure 9 shown: A positioning plate 351 is provided between the transmission rods 34 under the two driving members 33, and both transmission rods 34 pass through the positioning plate 351 and are slidably matched with it; A frame 35 is provided under the test base 1, and a lead screw 3511 and a track 3512 extending in the width direction of the test base 1 are provided on the frame 35. The positioning plate 351 is slidably arranged on the track 3512 and is sleeved on the lead screw 3511 and is threadedly matched with it.

[0047] By rotating the lead screw 3511, the movement of the positioning plate 351 threadedly matched with it can be driven, so that the positioning plate 351 can slide along the lead screw 3511. By the movement of the positioning plate 351, the movement of the two transmission rods 34 is driven, thereby adjusting the position of the transmission rods 34 in the width direction of the test base 1. By adjusting the position of the transmission rods 34, when the transmission rods 34 are lifted, the driving member 33 can be driven to move different distances, and the driving member 33 can be kept in a stable position after being locked. Through this adjustment process, the driving of the clamping arm 31 on the first pulley 32 can be precisely controlled, thereby precisely adjusting the docking effect between the slot 211 on the mounting plate 21 and the connector 11 on the test base 1, ensuring the stability and accuracy of the aging test.

[0048] By rotating the screw 3511 to adjust the positioning plate 351, the user can flexibly adjust the position of the transmission rod 34, so that the device can adapt to inverters 4 of different specifications or test requirements, providing higher operational flexibility. This adjustment mechanism greatly improves the versatility and adaptability of the device. The coordinated design of the positioning plate 351 and the screw 3511 ensures the accuracy of positioning and the stable movement of the transmission rod 34, and the self-locking property of the transmission through the screw 3511 enables the transmission rod 34 to maintain a stable position after being adjusted, avoiding unnecessary deviations, ensuring stability during long-term testing, and improving the reliability of the entire device. The simplified structural design also reduces the difficulty of maintenance, improves the ease of use and maintenance efficiency of the device.

[0049] like Figures 2 to 5 , Figure 8 and Figure 9 As shown: a transmission plate 342 is arranged between the transmission rods 34 below the two driving members 33, the transmission plate 342 is fixedly connected to the bottom of the two transmission rods 34, a slide groove 3421 extending along the axial direction of the screw rod 3511 is arranged in the center of the transmission plate 342, a slider 3521 is arranged on the slide groove 3421, and a linear driver 352 that can drive the slider 3521 to move along the axial direction of the transmission rod 34 is arranged at the bottom of the frame 35.

[0050] The movement of the positioning plate 351 will drive the transmission rod 34 to change its position along the width direction of the test seat 1. Since the transmission plate 342 is fixedly connected to the bottom of the transmission rod 34, and the linear driver 352 cannot move with the transmission plate 342, the displacement of the transmission plate 342 will cause the slide 3421 to move accordingly. The slide 3421 compensates for the relative position difference between the transmission plate 342 and the linear driver 352 by sliding the slider 3521, thereby ensuring that the linear driver 352 can always effectively drive the movement of the transmission plate 342 by driving the slider 3521. Through this mechanism, the transmission plate 342 moves smoothly along the axial direction of the transmission rod 34, thereby driving the transmission rod 34 to lift upward, thereby realizing precise driving and adjustment of the transmission rod 34.

[0051] Due to the relative motion design of the chute 3421 and the slider 3521, the linear actuator 352 can always maintain a stable and continuous driving state, avoiding jamming or uneven movement caused by position differences. This design ensures the stability of the lifting process of the transmission rod 34, and can guarantee a consistent working effect during long-term operation. It makes the relative position adjustment between the transmission plate 342 and the linear actuator 352 more direct and effective. Since the demand for complex components is reduced, the overall structure is more compact, and the maintenance difficulty of the device is also reduced accordingly, thereby reducing the maintenance cost during long-term use. Through the above precise adjustment and stable control, the device can maintain a high level of reliability and test accuracy during long-term high-precision operations such as aging tests. This not only improves the stability of the test results but also enhances the long-term use performance of the device. The linear actuator 352 is preferably a cylinder.

[0052] As Figures 2 to 7 shown: A guide rod 333 is provided at one end of the driving member 33 away from the mounting plate 21, a support plate 13 is provided at one end of the test seat 1 away from the mounting plate 21, a sleeve 3331 is provided on the support plate 13, the guide rod 333 is sleeved in the sleeve 3331 and an elastic member 3332 is provided in the sleeve 3331.

[0053] When the driving member 33 moves, the guide rod 333 slides along the axial direction of the sleeve 3331. The cooperation design of the guide rod 333 and the sleeve 3331 ensures that the driving member 33 is always on the correct path during movement, avoiding unstable movement caused by deviation or misalignment. The sliding function of the guide rod 333 can effectively guide the driving member 33, ensuring the accuracy of the movement direction and position, thereby improving the overall stability of the device. When the guide rod 333 moves into the sleeve 3331, it will drive the elastic member 3332 to be compressed. The elastic member 3332 provides the necessary elastic force for the guide rod 333. The elastic member 3332 can absorb part of the impact force and relieve the vibration or impact during the movement process. This buffering effect not only reduces the wear of the device and extends the service life of the device. At the same time, when the clamping arm 31 needs to release the clamping of the first pulley 32, the elastic reset of the elastic member 3332 helps the driving member 33 to reset, so that the clamping arm 31 can quickly move away from the first pulley 32, causing the socket of the mounting plate 21 and the connector 11 of the test seat 1 to separate. This structure not only reduces the manufacturing cost but also reduces the maintenance difficulty, further improving the economy and practicality of the device.

[0054] As Figures 2 to 7 shown: The sleeve 3331 is threadedly connected to the support plate 13.

[0055] Through the threaded connection between the sleeve 3331 and the support plate 13, the stability and firmness between the two are ensured. The threaded connection provides a tight connection, enabling the sleeve 3331 to effectively maintain its position during use, avoiding loosening or displacement, thereby enhancing the structural stability of the overall device. By means of the threaded connection, the position of the sleeve 3331 on the support plate 13 can be changed, thereby adjusting the position of the guide rod 333, and thus changing the initial position of the driving member 33 in the width direction of the test seat 1, thereby changing the clamping angle of the two clamping arms 31 in the initial state, and thus improving the adaptability of the device.

[0056] As Figures 2 to 5 shown: At one end of the mounting plate 21 close to the test seat 1, there are provided two limiting blocks 22, and the two limiting blocks 22 are respectively fixedly connected to both ends of the mounting plate 21 in the length direction, and the two limiting blocks 22 are both made of elastic materials.

[0057] The main function of the limiting block 22 is to ensure an appropriate distance between the mounting plate 21 and the test seat 1, avoiding excessive movement of the mounting plate 21 resulting in over-tight contact between the slot 211 and the joint 11, and thus preventing damage caused by over-pressurization or improper insertion. By effectively restricting the minimum distance between the two, the structural integrity of the slot 211 and the joint 11 is protected, ensuring that the device can be connected and tested in a stable state. The design of the limiting block 22 effectively restricts the excessive movement of the mounting plate 21, ensuring the docking stability between the slot 211 and the joint 11. During the aging test, a stable plug-in connection is crucial for the accuracy of the test results.

[0058] The simple design of the limiting block 22 reduces the complexity of the device and the cost of the traditional protection system. Its elastic material not only plays a protective role but also reduces the maintenance difficulty and frequency, and reduces the maintenance and replacement costs caused by damage.

[0059] As Figures 1 to 4 and Figure 10 shown: At the bottom of the mounting seat 2, there are provided a plurality of positioning grooves 23 for positioning the inverter 4, and a slidable positioning block 231 is provided on the positioning groove 23, and a fixing member 232 that is threadedly engaged with it is provided on the positioning block 231.

[0060] Through the design of the positioning groove 23 and the positioning block 231, the accurate position of the inverter 4 in the mounting seat 2 can be ensured. Through the guiding action of the positioning groove 23, the positioning block 231 can slide on the positioning groove 23 and fix the position of the inverter 4, avoiding instability or test errors caused by the position deviation of the inverter 4 during the aging test. This design ensures that the inverter 4 always maintains the correct fixed position during the test, providing an accurate test environment.

[0061] The positioning block 231 is designed to be slidable, enabling users to adjust the position of the inverter 4 according to the size and requirements of the inverter 4. In combination with the setting of the positioning groove 23, users can easily adjust the position of the positioning block 231 to adapt to different models or sizes of the inverter 4, providing flexibility and diverse adaptation solutions and enhancing the versatility of the device. By providing a fixing member 232 that is threadedly engaged with the positioning block 231, this threaded connection design can ensure that the positioning block 231 can be firmly fixed in the desired position after sliding. The threaded engagement provides a stable locking force, effectively preventing the positioning block 231 from loosening or shifting during operation, ensuring the stability and accuracy of the inverter 4 throughout the testing process. This simple fixing method makes the operation more intuitive and convenient, reducing the operation time and complexity and improving the efficiency of the testing process.

[0062] The above embodiments merely represent one or several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the appended claims.
