Description

Technical Field

[0001] The utility model relates to the technical field of testing and sorting equipment, in particular to a testing and sorting device. Background Art

[0002] With the continuous development of science and technology, the application of electronic components is becoming more and more extensive. Before leaving the factory, electronic components need to be tested and sorted in different test environments (high temperature, normal temperature and low temperature) to ensure that their quality meets the requirements.

[0003] In order to facilitate the control of the temperature of the test environment, a sealed chamber is provided inside the test sorting device, and the electronic components are placed in the sealed chamber for preheating or testing. The sealed chamber is conducive to creating a low dew point environment in a low temperature test environment (the temperature in the sealed chamber can be as low as -55°C in a low temperature test environment), reducing the consumption of dry gas, and avoiding frost and condensation inside the sealed chamber. However, in a high temperature test environment (the temperature in the sealed chamber can be as high as 150°C in a high temperature test environment), the heating elements inside the sealed chamber continue to work, causing the temperature inside the sealed chamber to rise. Excessive temperature will affect the service life of key components. There is no dew point requirement in a high temperature test environment, and the equipment does not need to be strictly sealed. The sealed chamber is cooled by a heat dissipation mechanism.

[0004] However, the traditional test and sorting device is connected to the axial fan through the tubular air duct. In the high temperature test environment, the fan is started to extract the high temperature gas in the sealed cavity. In the low temperature test environment, the fan is turned off, and the length of the air duct and the fan are used to prevent the dry gas from flowing out in large quantities. Since the tubular air duct is open, the sealing performance of the sealed cavity is poor in the low temperature test environment, and the external environment is easy to affect the dew point in the sealed cavity. Utility Model Content

[0049] See also Figure 1 and Figure 2 In one embodiment of the present application, a test sorting device 100 is provided for testing and sorting electronic components. Specifically, the electronic components are chips. It is understood that in other embodiments, the test sorting device 100 can also be used to test other types of semiconductor devices, which is not limited here.

[0050] The testing and sorting device 100 includes a main body 10, and a sealed cavity 11 is provided in the main body 10. The electronic components are placed in the sealed cavity 11 for preheating or testing. Optionally, a placement port is provided on the main body 10, and the electronic components can be placed in the sealed cavity 11 through the placement port or taken out of the sealed cavity 11. Figure 3 The main body 10 has at least one first opening 12 connected to the sealed cavity 11. The sealed cavity 11 can be connected to the outside through the first opening 12 to dissipate the heat in the sealed cavity 11 during high temperature testing, thereby maintaining the internal temperature of the sealed cavity 11 stable.

[0051] In some specific embodiments, the sealed cavity 11 is used for preheating electronic components. A preheating shuttle 90, a preheating plate 10 and other heating elements are provided in the sealed cavity 11. The first opening 12 is arranged close to the position where the heating element is provided in the sealed cavity 11 to discharge the heat generated by the heating element to the outside, thereby maintaining the temperature in the sealed cavity 11 stable.

[0052] Continue reading Figure 3 , the test and sorting device 100 also includes a door panel 20 and a fan 30. The door panel 20 is movably arranged on the main body 10 and corresponds to the first opening 12 one by one. The door panel 20 can be operably moved relative to the main body 10 to open the first opening 12 corresponding thereto or close the first opening 12 corresponding thereto. The fan 30 is arranged outside the sealed cavity 11. Specifically, the fan 30 is installed on the main body 10 and corresponds to the first opening 12 one by one. The fan 30 is used to provide a flow force for the airflow to flow through the sealed cavity 11 to the first opening 12 and to flow to the outside through the first opening 12. That is, when the first opening 12 is opened, the fan 30 can provide a suction force to draw the airflow in the sealed cavity 11 to the outside through the first opening 12. Specifically, the fan 30 is an axial flow fan.

[0053] With the above arrangement, during low temperature testing, the control door panel 20 closes the first opening 12, and the sealed chamber 11 can remain sealed, which is conducive to creating a low dew point environment during low temperature testing, reducing the consumption of dry gas, and avoiding condensation and frost inside the sealed chamber 11. During high temperature testing, the control door panel 20 opens the first opening 12, and the fan 30 provides suction force to extract the high temperature airflow in the sealed chamber 11 to keep the temperature in the sealed chamber 11 stable.

[0054] The test and sorting device 100 provided in the embodiment of the present application is different from the prior art method of connecting the axial flow fan 30 through a tubular air duct. In a high temperature environment, the door panel 20 is operated to open the first opening 12, and the fan 30 can extract the high temperature gas in the sealed cavity 11 to keep the temperature in the sealed cavity 11 stable. In a low temperature environment, the door panel 20 is operated to close the first opening 12. At this time, the sealed cavity 11 can maintain a high degree of sealing, which is conducive to creating a low dew point environment for the sealed cavity 11 in a low temperature environment, reducing the consumption of dry gas, and avoiding frost and condensation inside the sealed cavity 11. In addition, compared with the prior art method of connecting the axial flow fan 30 through a tubular air duct (the tubular air duct is longer, which will lose part of the pressure drop and the heat dissipation effect is average), the fan 30 is arranged close to the first opening 12, and the heat dissipation effect is better.

[0055] In some embodiments, see Figure 2 and Figure 3The main body 10 includes a cavity 13 and a mounting plate 14. The sealed cavity 11 is arranged in the cavity 13, and the cavity 13 is also provided with a second opening 15. The mounting plate 14 is installed at the position where the second opening 15 is provided in the cavity 13 and has a first opening 12, and the first opening 12 is connected to the second opening 15 in a one-to-one correspondence. The test sorting device 100 includes a heat dissipation mechanism, and the door panel 20 and the fan 30 are both arranged on the mounting plate 14. The heat dissipation mechanism includes the mounting plate 14, the door panel 20 and the fan 30 arranged in a one-to-one correspondence, and the heat dissipation mechanism is connected to the cavity 13 through the mounting plate 14. In this way, the heat dissipation mechanism is independently arranged from the cavity 13, so that different heat dissipation mechanisms can be selected according to needs.

[0056] Optionally, the heat dissipation mechanism is detachably connected to the cavity 13 via the mounting plate 14, and at the same time, the components of the heat dissipation mechanism are detachably connected, so as to facilitate replacement of the heat dissipation mechanism and the components.

[0057] It is understandable that in some other embodiments, the main body 10 may also omit the mounting plate 14 , in which case the first opening 12 is directly opened on the cavity 13 , and the door panel 20 and the fan 30 are also mounted on the cavity 13 .

[0058] In some embodiments, continue to refer to Figure 1 and Figure 2 , two second openings 15 are provided on the cavity 13, one second opening 15 is provided on the top surface of the cavity 13, and the other second opening 15 is provided on the side of the cavity 13, and the two second openings 15 are provided close to the heating element of the sealed cavity 11. At this time, the test sorting device 100 includes two heat dissipation mechanisms, and each second opening 15 is provided with a heat dissipation mechanism. In this way, during high temperature testing, the two heat dissipation mechanisms cooperate to dissipate the heat in the sealed cavity 11, ensuring the heat dissipation effect.

[0059] It is understandable that in some other embodiments, the number of the second openings 15 is not limited, that is, the number of the heat dissipation mechanisms is not limited. For example, the number of the second openings 15 can be one or more than two, and correspondingly, the number of the heat dissipation mechanisms can be one or more than two.

[0060] In some embodiments, at least one heat dissipation mechanism is a first heat dissipation mechanism A1, and the first heat dissipation mechanism A1 is disposed on the side of the cavity 13. The first heat dissipation mechanism A1 includes a driving member 40, the driving member 40 is mounted on the mounting plate 14, the door panel 20 is connected to the driving member 40, and the driving member 40 is used to drive the door panel 20 to move relative to the mounting plate 14 to open and close the first opening 12. In this way, when the first opening 12 needs to be opened and closed, the control mechanism controls the driving member 40 to drive the door panel 20 to move relative to the main body 10, thereby realizing the automatic opening and closing of the first opening 12, and the degree of automation is relatively high.

[0061] In some other embodiments, continue to refer to Figure 1 and Figure 2 At least one heat dissipation mechanism may be provided as a second heat dissipation mechanism A2, and the second heat dissipation mechanism A2 is provided on the top surface of the cavity 13. The second heat dissipation mechanism A2 is not provided with a driving member 40, and the door panel 20 is rotatably connected to the mounting plate 14. Figure 13-Figure 15 When the fan 30 is turned on to provide suction force, the door panel 20 can rotate relative to the mounting plate 14 to open the first opening 12 under the action of the suction force, and when the fan 30 is turned off, the door panel 20 can rotate relative to the mounting plate 14 to close the first opening 12 under the action of gravity. At this time, the first opening 12 can also realize the function of automatic opening and closing, and the degree of automation is relatively high. Generally, the door panel 20 is made of lightweight materials so that the door panel 20 can open the first opening 12 under the action of a relatively small suction force.

[0062] It is conceivable that in some other embodiments, the first heat dissipation mechanism A1 may be disposed on the top surface of the cavity 13 , and the second heat dissipation mechanism A2 may be disposed on the side surface of the cavity 13 , which is not limited here.

[0063] It should also be noted that when the test sorting device 100 has only one second opening 15, there is only one heat dissipation mechanism, and the heat dissipation mechanism can choose to use the first heat dissipation mechanism A1 or the second heat dissipation mechanism A2. When the test sorting device 100 has more than two second openings 15, the heat dissipation mechanism can all choose the first heat dissipation mechanism A1, can also choose the second heat dissipation mechanism A2, or partially choose the first heat dissipation mechanism A1 and the rest choose the second heat dissipation mechanism A2, which is not limited here.

[0064] Further reading Figure 3 and Figure 4 The test and sorting device 100 also includes an air guide structure 50, and an air guide channel 51 is formed in the air guide structure 50. An air guide structure 50 is provided corresponding to at least one first opening 12, and one end of the air guide channel 51 can be communicated with the first opening 12. The fan 30 is installed on the air guide structure 50 and is communicated with the other end of the air guide channel 51. Specifically, an air inlet 511 and an air outlet 512 are formed at both ends of the air guide channel 51, respectively, the air inlet 511 is communicated with the first opening 12, and the fan 30 is installed at the air outlet 512. The air guide structure 50 is used to guide the air flow to the fan 30 through the first opening 12. With such a configuration, when the fan 30 is turned on, the air flow in the sealed cavity 11 can flow out through the first opening 12, and be guided to the fan 30 for discharge through the air guide channel 51, so as to facilitate the discharge of the hot air flow in the sealed cavity 11.

[0065] It should be noted that all heat dissipation mechanisms may include the above-mentioned air guide structure 50 , or some heat dissipation mechanisms may include the above-mentioned air guide structure 50 .

[0066] In some embodiments, the door panel 20 is rotatably connected to the main body 10, and the driving member 40 can drive the door panel 20 to rotate relative to the mounting plate 14 to open and close the first opening 12. When the door panel 20 closes the first opening 12, the door panel 20 is located in the air guide channel 51 and is sealed with the channel wall of the air guide channel 51.

[0067] Specifically, see Figure 5 and Figure 6 The first heat dissipation mechanism A1 further includes a coupling 60 and a connecting block 70. The connecting block 70 is disposed in the air guide structure 50 and connected to the door panel 20. The exit end of the connecting block 70 passes through the air guide structure 50 and is connected to the driving end of the driving member 40 through the coupling 60. The driving member 40 drives the connecting block 70 to rotate through the coupling 60, thereby driving the door panel 20 to rotate to open and close the first opening 12. Optionally, the driving member 40 is a swing cylinder or a motor.

[0068] In some specific embodiments, the driving member 40 drives the door panel 20 to rotate at an angle of 90°, so that the door panel 20 is in a closed state of closing the first opening 12 (see Figure 7 ) and the opening state of the first opening 12 being fully opened (see Figure 8 In some other embodiments, the rotation angle of the door panel 20 driven by the driving member 40 is not limited.

[0069] Further reading Figure 3 The air guide structure 50 includes an air guide body 52 and a baffle 53 which are separately arranged. The air guide body 52 is connected to the mounting plate 14. The baffle 53 is fixedly mounted on the air guide body 52 and abuts against the mounting plate 14. The baffle 53 and the air guide body 52 together form an air guide channel 51, an air inlet 511 and an air outlet 512. The connecting block 70 is inserted through the baffle 53 (see FIG. Figure 4 and Figure 6 ). Such a configuration facilitates the installation of the air guide structure 50 and the door panel 20. It should be understood that in other embodiments, the air guide structure 50 may also be an integrated structure or formed in other ways, which is not limited here.

[0070] Continue reading Figure 6 The first heat dissipation mechanism A1 further includes a limiting structure 80, which includes a limiting protrusion 81 and a limiting hole 82. One of the limiting protrusion 81 and the limiting hole 82 is provided on the door panel 20, and the other is provided on the channel wall of the air guide channel 51. The limiting protrusion 81 is inserted into the limiting hole 82, and rotates in the limiting hole 82 when the door panel 20 rotates. The limiting protrusion 81 cooperates with the limiting hole 82 to increase the stability of the door panel 20 when it rotates.

[0071] In some other embodiments, see Fig. 9 and Fig.10The driving member 40 is used to drive the door panel 20 to move linearly relative to the mounting plate 14 to open and close the first opening 12. Specifically, the driving member 40 is a cylinder, and the driving end of the cylinder is connected to the door panel 20 to drive the door panel 20 to move linearly relative to the mounting plate 14.

[0072] Optionally, the door panel 20 is a grid-like structure. Fig.11 When the grille opening of the door panel 20 is aligned with the first opening 12, the first opening 12 is opened. Fig.12 When the grille opening of the door panel 20 is misaligned with the first opening 12, the first opening 12 is closed. In this way, the door panel 20 can open and close the first opening 12 by moving a short distance in a straight line. It should be understood that in some other embodiments, the door panel 20 can also be arranged in other ways, such as arranging the entire door panel 20 as a solid structure.

[0073] In some embodiments, see Fig. 9 and Fig.10 The air guide structure 50 includes an air guide body 52 and a moving plate 54, the moving plate 54 is connected to the driving end of the driving member 40, and the door panel 20 is connected to the moving plate 54. The driving member 40 can drive the moving plate 54 to move in a straight line, thereby driving the door panel 20 to move in a straight line to open and close the first opening 12. Further, when the door panel 20 closes the first opening 12, the door panel 20 is located between the air guide body 52 and the mounting plate 14, and the moving plate 54 and the air guide body 52 are against each other to form an air guide channel 51. In this way, the structure of the first heat dissipation mechanism A1 is compact, and the space occupied by the first heat dissipation mechanism A1 is reduced.

[0074] Continue reading Figure 13-Figure 15 The second heat dissipation mechanism A2 is also provided with an air guide structure 50, the fan 30 is mounted on the air guide structure 50, and the door panel 20 is rotatably connected to the mounting plate 14. In this way, the door panel 20 is convenient to rotate relative to the mounting plate 14 under the suction force of the fan 30 to open the first opening 12.

[0075] The test sorting device 100 provided in the embodiment of the present application has the following beneficial effects:

[0076] 1. In a high temperature environment, the door panel 20 is operated to open the first opening 12, and the fan 30 can extract the high temperature gas in the sealed cavity 11 to keep the temperature in the sealed cavity 11 stable. In a low temperature environment, the door panel 20 is operated to close the first opening 12, and the sealed cavity 11 can maintain a high degree of sealing, which is conducive to creating a low dew point environment in the sealed cavity 11 in a low temperature environment, reducing the consumption of dry gas, and avoiding frost and condensation inside the sealed cavity 11.

[0077] 2. The heat dissipation mechanism exists independently of the cavity 13, that is, the heat dissipation mechanism adopts a modular design, and the installation position, quantity or structure of the heat dissipation mechanism can be adjusted according to the heat source arrangement in the sealed cavity 11, and the installation and control method is simple and reliable.

[0078] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0079] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
