[0032] Next, refer to Figures 1-6 to describe the loading and unloading device 100 for an aging chamber according to an embodiment of the first aspect of the present invention

[0033] As Figures 1-6 shown, the loading and unloading device 100 for an aging chamber according to an embodiment of the first aspect of the present invention includes a mounting bracket 1, a driving module 2, a limiter, and a loading and unloading plate 4

[0034] Specifically, the mounting bracket 1 has a receiving cavity, and a sliding hole 11 is formed in the side wall of the mounting bracket 1, and the sliding hole 11 communicates with the receiving cavity. The driving module 2 includes a driving member 21 and a longitudinal rod 22. The longitudinal rod 22 is slidably fitted in the receiving cavity, and the driving member 21 provides a driving force for the longitudinal rod 22. The limiter is provided on the mounting bracket 1, and the first fastener 34 passes through the limiter and the sliding hole 11 and is connected to the longitudinal rod 22. The loading and unloading plate 4 is provided on one side of the mounting bracket 1 in the thickness direction. The loading and unloading plate 4 is connected to the longitudinal rod 22, and the loading and unloading plate 4 has a fitting portion 41, and the fitting portion 41 is adapted to cooperate with the groove 61 of the circuit board 6

[0035] For example, in Figures 1-5 the example, the mounting bracket 1 may be composed of two spaced-apart mounting plates, and the two mounting plates jointly define the receiving cavity. The sliding hole 11 may be formed on one side of the mounting bracket 1 in the width direction (for example, Figure 1 the front-back direction in Figure 1 ), and the sliding hole 11 extends along the length direction of the mounting bracket 1 (for example, Figure 1On one side (in the left - right direction in the figure), the first fastener 34 connects the stopper and the longitudinal rod 22, so that the stopper can move with the longitudinal rod 22. At the same time, the stopper can limit the moving distance of the longitudinal rod 22 to prevent the moving distance of the longitudinal rod 22 from being too large. The loading and unloading plate 4 is located on the side of the mounting bracket 1 in the thickness direction away from the stopper. The engaging portion 41 is located on the side of the loading and unloading plate 4 away from the longitudinal rod 22. The shape of the engaging portion 41 is L - shaped. Since the loading and unloading plate 4 is connected to the longitudinal rod 22, when the longitudinal rod 22 moves, it can also drive the loading and unloading plate 4 to move, so that the loading and unloading plate 4 can be connected to the circuit board 6 and drive the circuit board 6 to move, facilitating the loading and unloading of the circuit board 6.

[0036] Specifically, the driving member 21 provides power to the longitudinal rod 22, enabling the longitudinal rod 22 to move in the up - down direction. During the movement of the longitudinal rod 22, the longitudinal rod 22 drives the loading and unloading plate 4 to move in the up - down direction, so that the engaging portion 41 can cooperate with or separate from the groove 61 of the circuit board 6. The movement of the longitudinal rod 22 can be limited by the stopper to prevent the moving distance of the longitudinal rod 22 from being too long or too short, resulting in the engaging portion 41 and the groove 61 of the circuit board 6 not being on the same straight line and unable to complete the cooperation. Thus, by the power provided by the driving member 21, the longitudinal rod 22 drives the loading and unloading plate 4 to move, and by using the stopper, the engaging portion 41 of the loading and unloading plate 4 is made to cooperate with the groove 61 of the circuit board 6. The loading and unloading device 100 realizes automatically loading the circuit board 6 into the aging chamber for testing, and at the same time can ensure that the circuit board 6 is installed in place, and can also automatically take out the circuit board 6 from the aging chamber, saving labor costs and improving the testing efficiency of the aging chamber.

[0037] According to the loading and unloading device 100 for the aging chamber of the present invention, by setting the stopper and the loading and unloading plate 4, using the driving member 21 and the longitudinal rod 22 to drive the loading and unloading plate 4 to move, and using the stopper to limit the stroke of the loading and unloading plate 4, the engaging portion 41 can smoothly cooperate with or separate from the groove 61 on the circuit board 6. Thus, the loading and unloading device 100 can automatically load the circuit board 6 into the aging chamber for testing or take out the circuit board 6 from the aging chamber, realizing the automatic loading and unloading of the circuit board 6, saving labor, and ensuring the testing efficiency and accuracy of the aging chamber.

[0038] According to some embodiments of the present invention, as Figure 3 shown, the stopper includes a first connecting plate 31, a second connecting plate 32, and a first elastic member 33. The first connecting plate 31 is provided on one side of the mounting bracket 1 in the thickness direction. The second connecting plate 32 is provided on the other side of the mounting bracket 1 in the thickness direction. The first fastener 34 passes through the second connecting plate 32 and the sliding hole 11 and is connected to the first connecting plate 31. The second fastener 35 passes through the second connecting plate 32, the mounting bracket 1, and the first connecting plate 31 and is connected to the loading and unloading plate 4. One end of the first elastic member 33 is connected to the mounting bracket 1, and the other end of the first elastic member 33 is connected to the second fastener 35.

[0039] Referring to Figure 3 , the first connecting plate 31 and the second connecting plate 32 are inclinedly arranged on the mounting bracket 1. One end of the first connecting plate 31 in the length direction (for example, the front-back direction in Figure 1 ) is matched with the sliding hole 11 on the mounting bracket 1, and the other end of the first connecting plate 31 in the length direction is movably connected to the mounting bracket 1. One end of the second connecting plate 32 in the length direction is matched with the sliding hole 11 on the mounting bracket 1, and the other end of the second connecting plate 32 in the length direction is movably connected to the mounting bracket 1. Then, the first connecting plate 31 and the second connecting plate 32 are opposite to each other on both sides in the thickness direction of the mounting bracket 1, and the two ends of the first connecting plate 31 and the second connecting plate 32 in the length direction are connected to the mounting bracket 1 through the first fastener 34 and the second fastener 35. One end of the first elastic member 33 in the length direction is connected to the second fastener 35, and the other end of the first elastic member 33 is connected to the mounting bracket 1. Thus, the first connecting plate 31 is connected to the first elastic member 33. When the loading and unloading device 100 works, the longitudinal rod 22 moves in the up-down direction, and the first connecting plate 31 and the second connecting plate 32 also move with the longitudinal rod 22. At the same time, the first connecting plate 31 and the second connecting plate 32 will drive the loading and unloading plate 4 to move slightly in the front-back direction. When the second fastener 35 moves with the first connecting plate 31, it will pull the first elastic member 33 to stretch and contract.

[0040] Specifically, when the longitudinal rod 22 moves upward, the ends of the first connecting plate 31 and the second connecting plate 32 connected to the sliding hole 11 move upward, the stretching amount of the first elastic member 33 gradually decreases, and the above-mentioned ends of the first connecting plate 31 and the second connecting plate 32 push the loading and unloading plate 4 forward, so that the matching portion 41 can accurately match with the groove 61 of the circuit board 6. When the longitudinal rod 22 moves downward, the ends of the first connecting plate 31 and the second connecting plate 32 connected to the sliding hole 11 move downward, so that the loading and unloading plate 4 and the circuit board 6 move downward, the stretching amount of the first elastic member 33 gradually increases, and the above-mentioned ends of the first connecting plate 31 and the second connecting plate 32 push the loading and unloading plate 4 backward to place the circuit board 6 into the installation groove of the aging box, realizing the automatic loading and unloading of the circuit board 6.

[0041] Thus, the moving distances of the first connecting plate 31 and the second connecting plate 32 are limited by the first elastic member 33, so that the moving distance of the longitudinal rod 22 is also limited. Subsequently, the moving distance of the loading and unloading plate 4 is limited, ensuring that the matching portion 41 can just move below the groove 61 of the circuit board 6, enabling the matching portion 41 to accurately match with the groove 61 on the circuit board 6, realizing the automation of the loading and unloading of the circuit board 6, and improving the testing efficiency of the aging box.

[0042] According to some embodiments of the present invention, referring to Figure 5, the loading and unloading device 100 further includes an adjustment module. The adjustment module includes a third connecting plate 51, a fourth connecting plate 52 and two adjustment components. The two adjustment components are arranged at intervals along the length direction of the mounting bracket 1. The third connecting plate 51 and the fourth connecting plate 52 are respectively located on both sides of the mounting bracket 1 in the thickness direction. A third fastener 54 passes through the third connecting plate 51 and the sliding hole 11 and is connected to the fourth connecting plate 52. A fourth fastener 55 passes through the third connecting plate 51, the mounting bracket 1 and the fourth connecting plate 52 and is connected to the loading and unloading plate 4. One of the two adjustment components is connected to the third connecting plate 51.

[0043] As Figure 5 shown, the adjustment module is located in the middle of the mounting bracket 1. One end of the third connecting plate 51 and the fourth connecting plate 52 is matched with the sliding hole 11 through the third fastener 54. The other ends of the third connecting plate 51 and the fourth connecting plate 52 are movably connected to the mounting bracket 1, and the movement trajectories of the third connecting plate 51 and the fourth connecting plate 52 are the same as those of the first connecting plate 31 and the second connecting plate 32. There is a certain gap between the two adjustment components, and the surfaces of the two adjustment components facing each other are inclined surfaces. Among them, the third connecting plate 51 is connected to the adjustment component located below. When the third connecting plate 51 and the fourth connecting plate 52 move, the third connecting plate 51 will drive the adjustment component to move, and the moving paths of the third connecting plate 51 and the fourth connecting plate 52 are the length of the sliding hole 11, thereby limiting the moving distance of the third connecting plate 51 and the fourth connecting plate 52. When the inclined surfaces of the two adjustment components in contact with each other, the two adjustment components move simultaneously. By adjusting the moving distance of the adjustment component, the moving distance of the longitudinal rod 22 can be adjusted.

[0044] Furthermore, each adjustment component includes a locking member 531, a slider 532, a second elastic member 533, and a sliding shaft 534. The slider 532 is slidably arranged on the sliding shaft 534. The locking member 531 and the second elastic member 533 are sleeved on the sliding shaft 534 and are located on both sides of the slider 532. For example, in Figure 5 the example, the locking member 531, the slider 532 and the second elastic member 533 are arranged at intervals in the length direction of the mounting bracket 1, and the sliding shaft 534 is placed along the length direction of the mounting bracket 1. The locking member 531 is located on the side of the slider 532 away from the second elastic member 533, and the locking member 531 is sleeved on the sliding shaft 534 in a circular ring shape. The slider 532 is located between the locking member 531 and the second elastic member 533. Among them, the compression amount of the second elastic member 533 can be adjusted through the slider 532 and the locking member 531, so that the sliding distance of the third connecting plate 51 and the fourth connecting plate 52 on the sliding hole 11 can be adjusted, and further the adjustment of the moving distance of the loading and unloading plate 4 can be realized.

[0045] According to some embodiments of the present invention, both the mounting bracket 1 and the longitudinal rod 22 are multiple. In the description of the present invention, the meaning of "multiple" is two or more. The multiple mounting brackets 1 are arranged at intervals in the thickness direction of the mounting bracket 1, and the multiple mounting brackets 1 correspond to the multiple longitudinal rods 22 one by one. Refer to Figure 1 , there are 2 mounting brackets 1, and each mounting bracket 1 is connected with a longitudinal rod 22, so that the longitudinal rod 22 can drive the loading and unloading plate 4 on each mounting bracket 1 to move. Such a setting can ensure the connection reliability between the circuit board 6 and the loading and unloading plate 4, and at the same time can ensure that the circuit board 6 can move smoothly.

[0046] Further, there are multiple loading and unloading plates 4, and the multiple loading and unloading plates 4 correspond to the multiple longitudinal rods 22 one by one. Each loading and unloading plate 4 is arranged on one side of the mounting bracket 1 adjacent to the center of the multiple mounting brackets 1. For example, in Figure 1 's example, the multiple loading and unloading plates 4 are located on one side in the thickness direction of the mounting bracket 1, and each loading and unloading plate 4 extends along the length direction of the mounting bracket 1. The matching parts 41 on the multiple loading and unloading plates 4 are arranged along the length direction of the mounting bracket 1. Thus, on the one hand, the loading and unloading device 10 can connect multiple circuit boards 6 with the loading and unloading plates 4 at the same time, improving the working efficiency of the loading and unloading device 100; on the other hand, the multiple matching parts 41 can load the circuit boards 6 at different positions into the aging box, improving the applicability of the loading and unloading device 100.

[0047] According to some embodiments of the present invention, the driving module 2 further includes a first transverse rod 23 and a second transverse rod 24. The first transverse rod 23 is connected to the output shaft 25 of the driving member 21, and one end of each of the multiple longitudinal rods 22 is connected to the first transverse rod 23. The second transverse rod 24 is connected between two adjacent loading and unloading plates 4, and the second transverse rod 24 and the first transverse rod 23 are arranged at intervals along the length direction of the mounting bracket 1. As Figure 1 shown, there are two first transverse rods 23, and the two first transverse rods 23 are arranged at intervals along the length direction of the longitudinal rod 22. Both ends in the length direction of the first transverse rod 23 are connected with longitudinal rods 22. The output shaft 25 is located on the side of the driving member 21 away from the mounting bracket 1, and one end of the output shaft 25 is fixedly connected to the two first transverse rods 23. There are four second transverse rods 24, and the four second transverse rods 24 are arranged at intervals along the length direction of the longitudinal rod 22. Thus, by setting the first transverse rod 23, one driving member 21 can drive multiple longitudinal rods 22 to move at the same time. By setting the second transverse rod 24, it can be ensured that two longitudinal rods 22 can move synchronously, and the moving speeds of the two longitudinal rods 22 are the same.

[0048] Specifically, when the output shaft 25 moves downward, the output shaft 25 moves into the driving member 21, and the first transverse rod 23 moves downward, causing the longitudinal rod 22 connected to the first transverse rod 23 to also move downward. When the output shaft 25 moves upward, the output shaft 25 drives the first transverse rod 23 to move upward, and the longitudinal rod 22 also moves upward. Thus, the driving member 21 realizes the driving effect on the longitudinal rod 22.

[0049] According to some embodiments of the present invention, each loading and unloading plate 4 includes a plurality of sub-loading and unloading plates, which are arranged along the length direction of the longitudinal rod 22. Each sub-loading and unloading plate 4 has a plurality of engaging portions 41, which are arranged at intervals along the length direction of the longitudinal rod 22, and each engaging portion 41 extends along the width direction of the mounting bracket 1. Referring to Figure 1 , each loading and unloading plate 4 includes 2 sub-loading and unloading plates. The number of engaging portions 41 on each loading and unloading plate 4 can be 6. Four loading and unloading plates 4 are respectively mounted on two mounting brackets 1. The engaging portions 41 are paired in pairs. The engaging portions 41 can cooperate with the grooves 61 at both ends of the edge of the circuit board 6, and the force exerted on the circuit board 6 when the loading and unloading plate 4 pulls the circuit board 6 is relatively balanced. Moreover, the length of each sub-loading and unloading plate is short, which is convenient for processing and assembly.

[0050] According to some embodiments of the present invention, the driving member 21 is a cylinder. Thus, the automation of loading and unloading the circuit board 6 can be realized, which is convenient for implementing automated testing and saves labor costs.

[0051] An aging box (not shown in the figure) according to the second aspect embodiment of the present invention includes a loading and unloading device 100 for the aging box according to the above first aspect embodiment of the present invention.

[0052] According to the aging box of the embodiment of the present invention, by adopting the above loading and unloading device 100, the automated loading and unloading of the circuit board 6 can be realized, the labor cost is reduced, and the testing efficiency can be improved and the mismeasurement probability can be reduced.
