[0002] Before leaving the factory, the chip needs to undergo an aging test to detect the chip's service life and reliability. The chip aging test is generally completed in an aging test device.

[0003] The aging test equipment includes a test body, on which a test cavity and an opening connected to the test cavity are provided. The aging test equipment also includes a door mechanism installed on the test body, and a door plate of the door mechanism is used to open and close the opening. When the door plate opens the opening, the chip can be placed in the test cavity through the opening for testing, or the chip after the test can be taken out of the test cavity through the opening; when the door plate closes the opening, the door plate and the test body together form a sealed space, so that the chip is in a sealed environment to prevent the external environment from interfering with the chip test results.

[0045] See also Figure 1 In one embodiment of the present application, there is provided an aging test device 1000 for performing aging tests on products. Specifically, the product that the aging test device 1000 is used to test is a chip. In order to ensure the stability and reliability of the chip, aging testing is a very important part. By performing aging tests on the chip, its performance under long-term operation and stress conditions can be evaluated, and potential problems can be discovered and repaired in a timely manner. It should be understood that there is no limitation on the types of products that the aging test device 1000 is used to test. For example, in some other embodiments, the aging test device 1000 can also be used to test other electronic components.

[0046] The following is a detailed introduction of the present application by taking the aging test device 1000 applied to a chip test as an example. It is to be understood that the description is only for example and does not limit the protection scope of the present application.

[0047] The aging test device 1000 includes a test body 200, in which a test cavity is provided, and the test body 200 is also provided with an opening 201 which is connected to the test cavity. The aging test device 1000 also includes a door mechanism 100, which is assembled to the test body 200 and is used to open and close the opening 201. Specifically, when testing the chip, the door mechanism 100 opens the opening 201, and the chip is placed in the test cavity through the opening 201, and then the door mechanism 100 closes the opening 201. When the chip test is completed, the door mechanism 100 opens the opening 201 again, and the chip in the test cavity can be taken out through the opening 201. After the chips after the test are taken out, the above steps can be repeated to test the next batch of chips.

[0048] For further information, see Figure 2 and Figure 3 , the door mechanism 100 includes a first drive assembly 10, a second drive assembly 20 and a door panel 30. The first drive assembly 10 can drive the door panel 30 to move relative to the test body 200 along the first direction X, so that the door panel 30 switches between a first position that closes the opening 201 and a second position that opens the opening 201. Specifically, the first drive assembly 10 can drive the door panel 30 to move relative to the test body 200 along the first direction X to maintain facing the opening 201, so that the door panel 30 switches between the first position that closes the opening 201 and the second position that opens the opening 201. It should be noted here that when the door panel 30 is in the second position, the opening 201 is open, which means that the opening 201 is in a connected state with the outside world, at which time the door panel 30 faces the opening 201 in the first direction X, and will not interfere with the test body 200 when it moves in the second direction Y later.

[0049] The second driving assembly 20 can drive the door panel 30 to move along the second direction Y to switch between the second position and the third position of fully opening the opening 201. It should be noted that when the door panel 30 is in the third position, the opening 201 is fully opened, which means that the opening 201 is in a state of communication with the outside world. At this time, the door panel 30 is misaligned with the opening 201 in the first direction X, so that the chip is placed in the test cavity facing the opening 201 or the chip in the test cavity is taken out facing the opening 201.

[0050] See also Figure 3-Figure 5 The door mechanism 100 further includes a first guide assembly, which includes a first guide member 41 and a second guide member 42. The first guide member 41 is connected to the door panel 30, and the second guide member 42 is misaligned with the opening 201 in the first direction X and remains relatively fixed with the opening 201, that is, the second guide member 42 remains relatively fixed with the test body 200. When the door panel 30 moves between the second position and the third position, the first guide member 41 is slidably connected with the second guide member 42 to guide the door panel 30 in the second direction Y.

[0051] The first direction X intersects with the second direction Y. Specifically, the first direction X is perpendicular to the second direction Y. In some specific implementations, the test body 200 is a hollow rectangular parallelepiped structure, the first direction X is perpendicular to the plane where the opening 201 is located, and the second direction Y is parallel to the plane where the opening 201 is located. The first direction X is the width direction of the test body 200, and the second direction Y is the length direction of the test body 200.

[0052] It should be understood that in some other embodiments, the shape of the test body 200 is not limited. At the same time, the relationship between the plane where the opening 201 is located and the first direction X and the second direction Y is not specifically limited. As long as it can ensure that the first drive component 10 and the second drive component 20 cooperate to drive the door panel 30 to open and close the corresponding opening 201, any arrangement method is acceptable.

[0053] It should be noted that when the door panel 30 is in the second position, the first guide member 41 and the second guide member 42 are directly opposite in the second direction Y. This means that when the door panel 30 is in the second position, the first guide member 41 and the second guide member 42 are exactly aligned in the second direction Y. However, at this time, the first guide member 41 and the second guide member 42 are not connected. When the door panel 30 moves from the second position to the third position, or moves from the third position to the second position, the first guide member 41 and the second guide member 42 slide and cooperate to guide the door panel 30.

[0054] According to the above arrangement, when it is necessary to place a chip into the test cavity or take the chip out of the test cavity, the first drive assembly 10 drives the door panel 30 to move along the first direction X, so that the door panel 30 moves from the first position to the second position. When the door panel 30 is in the second position, the second drive assembly 20 drives the door panel 30 to move along the second direction Y, and the test body 200 does not interfere with the movement of the door panel 30. When the door panel 30 moves from the second position to the third position, the opening 201 is fully opened. After the chip is placed and taken, the second drive assembly 20 drives the door panel 30 to move along the second direction Y, so that the door panel 30 moves from the third position to the second position. Then the first drive assembly 10 drives the door panel 30 to move along the first direction X directly facing the opening 201, so that the door panel 30 moves from the second position to the first position. In the process of the door panel 30 moving between the second position and the third position, the first guide member 41 and the second guide member 42 cooperate to guide the door panel 30.

[0055] In the aging test device 1000 provided in the embodiment of the present application, since the second guide member 42 is fixedly arranged relative to the test body 200, when the second drive assembly 20 drives the door panel 30 to move between the second position and the third position, the first guide member 41 and the second guide member 42 cooperate to guide the door panel 30, so as to prevent the door panel 30 from deviating during the movement in the second direction Y, thereby ensuring that the door panel 30 is reset to the initial position when the opening 201 is closed again. Compared with the situation in the prior art that the door panel 30 cannot be reset to the initial position, the sealing effect of the door panel 30 sealing the opening 201 is ensured. At the same time, in the present application, the door panel 30 and the opening 201 are misaligned in the first direction X by the drive assembly of the door mechanism 100, and there is no need to set up another structure to achieve the misalignment of the door panel 30 and the opening 201, so that the structure of the entire aging test device 1000 is simple.

[0056] In some embodiments, the first drive assembly 10 is disposed on the test body 200, the second drive assembly 20 is disposed on the first drive assembly 10, and the door panel 30 is connected to the second drive assembly 20. At this time, the first drive assembly 10 can drive the second drive assembly 20 to move along the first direction X, so as to drive the door panel 30 to move along the first direction X. The second drive assembly 20 can drive the door panel 30 to move along the second direction Y relative to the first drive assembly 10.

[0057] In some other embodiments, the second drive assembly 20 may be disposed on the test body 200, the first drive assembly 10 may be disposed on the second drive assembly 20, and the door panel 30 may be connected to the first drive assembly 10. At this time, the first drive assembly 10 drives the door panel 30 to move along the first direction X relative to the second drive assembly 20, and the second drive assembly 20 can drive the first drive assembly 10 to move along the second direction Y, so as to drive the door panel 30 to move along the second direction Y.

[0058] Optionally, continue to Figure 4 The first driving assembly 10 includes a first driving module 11 and a second driving module 12. The first driving module 11 and the second driving module 12 are arranged at intervals in the third direction Z and are both connected to the test body 200. The second driving assembly 20 is arranged on the second driving module 12, and the door panel 30 is connected to the second driving assembly 20. In this way, the first driving module 11 and the second driving module 12 cooperate to drive the door panel 30 in the first direction X facing the opening 201, so that the door panel 30 moves between the first position and the second position. When the door panel 30 is in the second position, the second driving assembly 20 can drive the door panel 30 to move along the second direction Y, so that the door panel 30 moves to the third position.

[0059] The second direction Y, the first direction X and the third direction Z intersect each other. Specifically, the second direction Y, the first direction X and the third direction Z are perpendicular to each other. When the test body 200 is a hollow rectangular parallelepiped structure, the third direction Z is the height direction of the test body 200.

[0060] It should be noted here that the above-mentioned first driving module 11 can cooperate with the second driving module 12 to drive the door panel 30 in the first direction X, and when the door panel 30 moves to the second position, the first driving module 11 and the second driving module 12 will not restrict the door panel 30 from moving along the second direction Y between the second position and the third position.

[0061] In some embodiments, continue to refer to Figure 2 and Figure 3 , the first driving module 11 and the second driving module 12 both include a first driving member 111. Specifically, the first driving module 11 and the second driving module 12 both include at least two first driving members 111 spaced apart in the second direction Y. Each first driving member 111 cooperates with the first direction X to drive the door panel 30 to move between the first position and the second position, so as to ensure the stability of the movement of the door panel 30 between the first position and the second position. Specifically, the first driving members 111 are all first cylinders. Of course, in some other embodiments, the first driving member 111 can also be arranged in other ways, such as arranging the first driving member 111 to include a motor and a transmission member, and the motor drives the door panel 30 to move along the first direction X through the transmission member.

[0062] Further, one end of the door panel 30 in the third direction Z is connected to the second drive assembly 20, and the first guide member 41 is provided at the other end of the door panel 30 in the third direction Z. The first drive module 11 also includes a connecting plate 112, and the connecting plate 112 is connected to the first drive member 111. The door panel 30 is connected to the connecting plate 112 in the first direction X by the first guide member 41, and is connected in a sliding manner in the second direction Y. When the door panel 30 is in the second position, the first guide member 41 is disengaged from the second guide member 42 and connected to the connecting plate 112, and the first drive module 11 can drive the door panel 30 to move between the first position and the second position through the connecting plate 112. When the door panel 30 moves between the second position and the third position, the connecting plate 112 can cooperate with the first guide member 41 to guide the door panel 30. In this way, when the door panel 30 moves between the second position and the third position, the connecting plate 112 and the second guide member 42 cooperate with the first guide member 41 to guide the door panel 30, and the door panel 30 will not deviate under the dual guiding action of the connecting plate 112 and the second guide member 42.

[0063] In some embodiments, continue to refer to Figure 5The first guide member 41 is a cam guide, the second guide member 42 is a guide rail, and is provided with a guide groove 421 extending along the second direction Y, and the connecting plate 112 is provided with a tensioning groove 1121. When the door panel 30 moves between the second position and the third position, the cam guide enters the guide groove 421 and moves in the guide groove 421 to guide the door panel 30. When the door panel 30 is in the second position, the cam guide is separated from the guide groove 421 and enters the tensioning groove 1121. When the door panel 30 moves between the second position and the third position, the cam guide is slidably matched with the guide groove 421 and the tensioning groove 1121 to guide the door panel 30.

[0064] Furthermore, when the door panel 30 moves between the second position and the third position, the circumferential surface of the cam guide slides with the side wall of the guide groove 421 and the side wall of the tension groove 1121, and there is a gap between the axial end surface of the cam guide and the bottom wall of the guide groove 421 and the bottom wall of the tension groove 1121. In this way, the weight of the door panel 30 will not act on the bottom wall of the guide groove 421 and the bottom wall of the tension groove 1121 through the cam guide, which can reduce the deformation of the second guide member 42 and the connecting plate 112, and avoid the cam guide from being stuck in the process of moving in the guide groove 421 and the tension groove 1121.

[0065] It should be understood that in some other embodiments, there is no limitation on the arrangement of the first guide member 41, the second guide member 42 and the connecting plate 112. For example, in some other embodiments, the first guide member 41 can also be arranged to include a slider, and the second guide member 42 and the connecting plate 112 can both include a slide rail that cooperates with the slider.

[0066] See also Figure 6 The first guide assembly further includes a third guide member 43 and a fourth guide member 44 that are slidably matched. The third guide member 43 is fixedly connected to the second driving assembly 20 and is at least partially opposite to the second guide member 42 in the first direction X. The fourth guide member 44 is fixedly connected to the door panel 30. When the door panel 30 moves between the second position and the third position, the third guide member 43 and the fourth guide member 44 cooperate to guide the door panel 30.

[0067] The third guide member 43 cooperates with the fourth guide member 44 to guide the movement of the door panel 30 in the second direction Y. The guide length is greater than or equal to the sum of the guide lengths of the second guide member 42 and the connecting plate 112 in the second direction Y, so that the door panel 30 is always connected to the third guide member 43 through the fourth guide member 44, and the fourth guide member 44 will not be separated from the third guide member 43. In some specific embodiments, the length of the third guide member 43 in the second direction Y is greater than or equal to the sum of the lengths of the second guide member 42 and the connecting plate 112 in the second direction Y. Specifically, the length of the third guide member 43 in the second direction Y is equal to the sum of the lengths of the second guide member 42 and the connecting plate 112 in the second direction Y.

[0068] Since the second drive assembly 20 is connected to the second drive module 12, the third guide member 43 is fixedly connected to the second drive assembly 20, and the fourth guide member 44 is fixedly connected to the door panel 30. When the second drive module 12 cooperates with the first drive module 11 to drive the second drive assembly 20 to move in the first direction X, the third guide member 43 follows the second drive assembly 20 to move in the first direction X, and the fourth guide member 44 follows the door panel 30 to move in the first direction X. In the process of moving in the first direction X, the third guide member 43 and the fourth guide member 44 are always in a relatively static state, that is, the third guide member 43 and the fourth guide member 44 are always in an aligned state. Since the second guide member 42 is fixedly arranged relative to the test body 200, when the door panel 30 moves to the second position, the first guide member 41 and the second guide member 42 need to be re-aligned. Because the third guide member 43 and the fourth guide member 44 are always in alignment, the first guide member 41 can easily slide to align with the second guide member 42, thereby avoiding the phenomenon that the first guide member 41 and the second guide member 42 cannot be aligned.

[0069] Optionally, the third guide member 43 is a guide rail, and the fourth guide member 44 is a slider. Of course, in other embodiments, the types of the third guide member 43 and the fourth guide member 44 are not limited.
