However, as the use time increases, the internal electronic components of the refrigerator controller may age, which in turn affects the working accuracy and reliability of the refrigerator controller. Therefore, in order to ensure the quality of the refrigerator, it is particularly important to test the normal operation of the refrigerator controller.

DETAILED DESCRIPTION
[0035] The following is combined with Figure 1-7 This application is described in further detail.
[0036] The present application embodiment discloses an aging detection device for a refrigerator controller. Figure 1 and Figure 2 The aging detection device of the refrigerator controller includes a detection platform 1. A plurality of detection stations 2 are arranged on the upper surface of the detection platform 1 along its circumference. Each detection station 2 is provided with a detection system 3. The detection system 3 includes a load and a detection module. The load can be specifically a compressor, which is used to be electrically connected to the product under test 9 and is controlled by the product under test 9 to realize opening and closing; the detection module is used to detect the electrical performance parameters of the product under test 9. The detection module is electrically connected to a main controller 4. The main controller 4 is used to obtain and output the detection result of the detection module so that the detection personnel can know the detection result. Accordingly, the main controller 4 can be specifically a PLC controller, and the detection module can be specifically a multimeter. The main controller 4 can output the detection result by means of an external display screen.
[0037] Reference Figure 1 and Figure 2A conveying assembly 11 is also provided on the testing platform 1. The conveying assembly 11 is used to drive all the testing stations 2 to move along the circumferential direction of the testing platform 1. Specifically, the conveying assembly 11 includes a moving frame 111 with a pulley, a conveying track arranged on the surface of the testing platform 1 along the circumference of the testing platform 1, a chain connected to all the moving frames 111, a sprocket connected to the chain, and a motor for driving the sprocket to rotate, and the motor is connected to the testing platform 1; each testing station 2 corresponds to a moving frame 111, and the testing station 2 is arranged on the moving frame 111.
[0038] Reference Figure 1 and Figure 2 , the conveying assembly 11 is controlled by the main controller 4, and the main controller 4 is also electrically connected to an alarm 41. Each moving frame 111 corresponds to an alarm 41, and the alarm 41 can be specifically an audible and visual alarm. The main controller 4 is used to obtain the detection start time of each detection station 2, and based on the preset specified detection duration, determine the detection completion time of each detection station 2 (that is, the detection completion time = detection start time + specified detection duration), and is also used to control the alarm 41 on the corresponding detection station 2 to start when the current time reaches any detection completion time, so as to remind the detection personnel to replace the detected product 9 on the corresponding detection station 2. Among them, whenever the load is connected to the detected product 9 and started, the current time is considered to be the detection start time of the corresponding detection station 2.
[0039] Reference Figure 1 and Figure 2The main controller 4 is also used to adjust the conveying speed of the conveying component 11 to the detection station 2 (i.e., adjust the motor speed) according to the detection completion time of each detection station 2, so that when the current time reaches the target detection completion time, the detection station 2 corresponding to the target detection completion time moves to the designated area. Specifically, the designated area refers to an area that needs to be manually set and used to replace the detected product 9 on the detection station 2 (the area shown by the arrow D in the figure). This application stipulates that it is necessary to take out the detected product 9 in the designated area and install the undetected product 9 on the detection station 2. Combined with the moving path of the detection station 2 disclosed in the embodiment of the present application, it can be known that the detection station 2 of the present application will move to the designated area every time it moves one circle after the detection start time, so the designated detection time = (total length of the moving path ÷ moving speed of the target detection station 2) + replacement time t for each detection station 2 to replace the tested product 9 * the number a of the detection stations 2 that need to replace the tested product 9; the present application assumes that all detection stations 2 are pre-numbered in ascending order according to Arabic numerals, and at the initial startup detection, the detection station 2 at the first place in the numbering sequence is located in the designated area, and only after all detection stations 2 are connected to the tested product 9, all detection stations 2 are driven to start moving through the conveying component 11. After that, whenever any detection station 2 moves to the designated area, it will pause for t time and then restart. Therefore, the number a refers to the number of detection stations 2 that reach the designated area before the target detection station 2 after all detection stations 2 start moving and need to replace the tested product 9. The number a = the number of the target detection station 2 - the number of the first in the detection sequence.

[0043] Reference Figure 5 , Figure 6 and Figure 7 A support plate 24 is provided between the loading track 21 and the unloading track 22, and a conveyor belt is provided on the surface of the support plate 24, and the conveying direction of the conveyor belt is parallel to the length direction of the unloading track 22. Each inspection station 2 also includes a replacement mechanism 7, which includes a sliding assembly 71 and a lifting assembly 72. The sliding assembly 71 includes a first sliding member 711 and a second sliding member 712. The first sliding member 711 is used to push the plug-in board 6 at the bottom of the feed box 5 out of the feed box 5 and push it to the support plate 24 along the length direction of the loading track 21. The second sliding member 712 is used to drive the support plate 24 to slide back and forth in a direction parallel to the length direction of the loading track 21 and the unloading track 22.
[0044] The lifting assembly 72 is used to drive the support plate 24 to slide back and forth along the height direction of the detection station 2. Specifically, the lifting assembly 72 includes a combination structure of a motor screw and a support block threadedly sleeved on the screw. The second sliding member 712 can be a pneumatic slide arranged on the support block. The support plate 24 is installed on the driving end of the pneumatic slide.

The detection station 2 is provided with symmetrically arranged baffles 26, and the connection area 23 is located between the two baffles 26. When the pad 63 slides with the plug-in board 6 in the direction close to the connection area 23, the baffle 26 is located on the sliding path of the pad 63.
[0045] The interface end plate 62 is also provided with a clamping member 8, which includes a pressing block 81, a pressure plate 82 and a second spring 83. The pressing block 81 disclosed in the embodiment of the present application is specifically a ball, and a plurality of balls are evenly inserted along the circumference of the inner wall of each socket slot 652. The pressure plate 82 is connected to the interface end plate 62 by sliding in the direction of approaching or moving away from the socket slot 652, and the second spring 83 is connected between the pressure plate 82 and the interface end plate 62, and the expansion and contraction direction of the second spring 83 is parallel to the sliding direction of the pressure plate 82 relative to the interface end plate 62.
[0046] The pressure plate 82 is provided with a ring block 84 near the position of each socket slot 652 and located on the outer periphery of the socket slot 652, and when the pressure block slides in the direction close to the socket slot 652, the thickness of the ring block 84 gradually decreases along the aforementioned sliding direction. The ring block 84 is used to press the pressing block 81 in the corresponding socket slot 652 when it is close to the corresponding socket slot 652, so that the pressing block 81 moves in the direction away from the ring block 84 and squeezes the interface of the product 9 under test located in the socket slot 652.

[0048] The implementation principle of an aging detection device for a refrigerator controller in an embodiment of the present application is as follows: after any detection station 2 is transferred to the designated area, the lifting assembly 72 is first used to drive the supporting plate 24 to move upward in the length direction of the unloading track 22. At this time, the plug-in plate 6 moves upward, and the interface of the tested product 9 in the interface end plate 62 is clamped by the clamping member 8, so that the interface of the tested product 9 and the load interface 31 are separated from each other; then, the supporting plate 24 is driven by the second sliding member 712 to move in a direction away from the connection area 23, so that the interface end plate 62 is disengaged from between the two baffles 26. At this time, the end of the pressing plate 82 is disengaged from the limiting groove 262 and moves upward, so that the clamping member 8 releases the clamping force on the interface of the tested product 9. When the supporting plate 24 moves to the unloading track 22, the conveyor belt preset on the upper surface of the supporting plate 24 is used to convey the tested product 9 to the slope 25, and the material is dropped under the guidance of the slope 25.
[0049] Then, the second sliding member 712 and the lifting assembly 72 are driven to move the support plate 24 to the end of the loading track 21, and then the first sliding member 711 is used to push the tested product 9 and its plug-in board 6 at the bottom of the feeding box 5 out of the feeding box 5, and move them to the support plate 24 under the guidance of the first track, until the interface end plate 62 on the current support plate 24 is inserted between the two baffles 26 by the push of the first sliding member 711. In this process, the end of the pressing plate 82 is inserted into the limit of the side wall of the docking block 261 The interface end plate 62 is pressed down by the lifting assembly 72, and moves toward the direction close to the socket slot 652 under the pressure of the inner wall of the limit slot 262, so that the pressure block 81 squeezes and clamps the interface of the product 9 under test in the socket slot 652; then the supporting plate 24 is driven downward by the lifting assembly 72, and at this time, the docking block 261 presses down the interface end plate 62 and moves downward together, until the interface end plate 62 moves down to make the interface of the product 9 under test connected to the load interface 31, thereby realizing the electrical connection between the product 9 under test and the load, and the replacement of the product 9 under test at the designated area.
