Usually, the test sorting machine includes a test box, a test bench is arranged inside the test box, and an operation window is arranged on the test box. The external material transfer robot places the device to be tested on the test bench through the operation window and then withdraws, and then the crimping head of the crimping device extends into the test box to crimp the device to be tested on the test bench.

[0003] In the related art, the specifications of the material transfer robot are smaller than those of the crimping head. In order to make the operation window compatible with the material transfer robot and the crimping head, the size of the operation window is often opened according to the size of the crimping head. In this way, when the material transfer robot loads the material, since the robot only occupies part of the operation window, the test box is prone to air leakage at the operation window, which reduces the sealing of the test box, and external water vapor can easily enter the test box. Under low-temperature test conditions, frost and condensation will occur on the surface of the device to be tested, affecting the performance test of the semiconductor device. Utility Model Content

[0043] The embodiments of the present application propose a test box and a test sorting machine to address the problem that the operating window of the test box is prone to air leakage, which reduces the sealing of the test box and easily leads to frost and condensation on the surface of the device to be tested under low-temperature test conditions, thereby affecting its performance test.

[0044] The test box provided in the embodiment of the present application is used in conjunction with a material transfer robot and a crimping device in actual application. The test box has a test chamber, and a test bench for performance testing of the device to be tested is usually provided in the test chamber. The material transfer robot is used to deliver the device to be tested from the operating window of the test box into the test chamber and / or to take out the tested device from the test chamber through the operating window of the test box. The material transfer robot can fix the device to be tested by clamping, adsorption, etc. Among them, the device to be tested can be, but is not limited to, a semiconductor device, such as a chip.

[0045] The crimping device is used to extend into the test cavity through the operating window and crimp the device to be tested on the test bench so that the device to be tested is connected to the test circuit on the test bench. In some examples, the crimping device includes a crimping head, which is used to extend into the test cavity and crimp the device to be tested. It is possible that a thermostat is set on the crimping head, and the thermostat is used to regulate the temperature of the device to be tested, including but not limited to a heating plate, a liquid cooling plate, etc. The temperature of the thermostat is transmitted to the device to be tested through the crimping head to help achieve performance testing of the device to be tested at different temperatures. In a further example, the crimping device also includes a sealing cover, and the sealing cover and the crimping head can be directly connected or indirectly connected. For example, the crimping device also includes a floating structure, and the sealing cover and the crimping head are both arranged on the floating structure. The floating structure can reduce the hard collision between the device to be tested and the test bench when the crimping head drives the device to be tested to connect with the test bench, and can also avoid the hard collision between the sealing cover and the test box. The floating structure can include a floating spring, a floating cylinder, etc. In actual application, when the crimping head is crimped into place, the sealing cover is located outside the test cavity and can cover the operation window of the test box.

[0046] The test box of the embodiment of the present application is first described in detail below.

[0047] Figure 1 This is a schematic diagram of the structure of a test box according to some embodiments of the present application. Figure 2 for Figure 1 An exploded view of the test box is shown. Figure 3 for Figure 1 Schematic diagram of the cover structure of the test box shown.

[0048] See also Figure 1 , Figure 2 and Figure 3 The test box 100 provided in some embodiments of the present application includes a box body 10, a first opening and closing assembly 20, and a second opening and closing assembly 30. The box body 10 forms a test cavity Q and includes an operation window K. The operation window K is used for allowing the material transfer robot 200 and the crimping device 300 to extend into the test cavity Q. The first opening and closing assembly 20 and the second opening and closing assembly 30 are both arranged on the box body 10. Among them, the first opening and closing assembly 20 is used to open and close the entire area of ​​the operation window K to allow the material transfer robot 200 and the crimping device 300 to pass through the operation window K. When the material transfer robot 200 passes through the operation window K through a part of the operation window K, an open area K1 capable of exposing the test cavity Q is formed between the material transfer robot 200 and the inner wall of the operation window K. The second opening and closing assembly 30 is used to open and close the open area K1, and can open the open area K1 when the crimping device 300 passes through the operation window K, and can also close the open area K1 when the material transfer robot 200 passes through the operation window K.

[0049] The operation window K is a window on the box 10 through which the material transfer robot 200 and the crimping device 300 pass, and it connects the inside and outside of the test cavity Q. The material transfer robot 200 delivers the device to be tested into the test cavity Q and / or takes out the tested device from the test cavity Q through the operation window K, and the crimping device 300 extends into the test cavity Q through the operation window K and crimps the device to be tested in the test cavity Q. It can be understood that in the embodiment of the present application, the "crimping device 300 passing through the operation window K" refers to the crimping head of the crimping device 300 passing through the operation window K.

[0050] The box body 10 is provided with a first opening and closing assembly 20, which can open and close the entire area of ​​the operation window K, that is, the test box 100 can completely open and close the operation window K through the first opening and closing assembly 20. In actual application, when the material transfer robot 200 and the crimping device 300 are not working (that is, no operation window K is provided), Figure 1 As shown, the first opening and closing component 20 closes the entire operation window K. When the material transfer robot 200 or the crimping device 300 needs to penetrate the operation window K, the first opening and closing component 20 opens the entire operation window K.

[0051] In actual application, when the crimping head of the crimping device 300 penetrates the operation window K, the sealing cover 301 of the crimping head 300 can cover the operation window K, so that during the operation of the crimping device 300, water vapor basically does not pass through the operation window K and enter the test cavity Q. However, the size of the material transfer robot 200 is usually smaller than the size of the crimping head. The material transfer robot 200 only penetrates the operation window K through a part of the operation window K. The area in the operation window K that is not penetrated by the material transfer robot 200 is the open area K1 defined between the material transfer robot 200 and the inner wall of the operation window K. The open area K1 is connected to the inside and outside of the test cavity Q in the open state, and allows external water vapor to enter the test cavity Q.

[0052] In order to prevent water vapor from entering the test chamber Q through the open area K1, refer to Figure 4 and Figure 5 , Figure 4 for Figure 1 The application schematic diagram shows that the second opening and closing assembly 30 of the test box 100 is in an open state. Figure 5 for Figure 1 The application schematic diagram shows that the second opening and closing component 30 of the test box 100 is in a closed state. In the embodiment of the present application, a second opening and closing component 30 is further provided on the box body 10, and the second opening and closing component 30 can open and close the open area K1.

[0053] In actual application, when the crimping head of the crimping device 300 passes through the operation window K, the second opening and closing component 30 is in a state of opening the operation window K, that is, opening the open area K1, so that the crimping head of the crimping device 300 passes through the operation window K. When the material transfer robot 200 passes through the operation window K, the second opening and closing component 30 closes the open area K1 to prevent water vapor from entering the test cavity Q through the open area K1.

[0054] In actual application, the test box 100 described above can open all the operation windows K when the material transfer robot 200 and the crimping head of the crimping device 300 need to be penetrated by the operation window K, and can close all the operation windows K when the material transfer robot 200 and the crimping device 300 are not working, thereby reducing the water vapor from entering the test cavity Q through the operation window K. Moreover, when the robot penetrates the operation window K, the second opening and closing component 30 can be used to close the open area K1 of the operation window K not penetrated by the material transfer robot 200, thereby reducing the external water vapor from entering the test cavity Q through the open area K1, thereby reducing the risk of frost and condensation in the test cavity Q under a low-temperature test environment, and reducing the adverse effects on the performance test of the device to be tested.

[0055] In some embodiments, the box body 10 is provided with an air inlet 13, and the air inlet 13 is used to supply air into the test chamber Q. That is, the air inlet 13 is used to supply gas into the test chamber Q. The gas introduced into the test chamber Q can be normal temperature gas, high temperature gas, low temperature gas, etc., so as to adjust the temperature in the test chamber Q to the required test temperature. The air inlet 13 can be an air inlet hole, an air inlet interface, etc., which is not specifically limited. At this time, the air supply method can be adopted to create the environment in the test chamber Q, which is low in cost and has good temperature uniformity in the test chamber Q.

[0056] Of course, in other embodiments, the ambient temperature in the test cavity Q may also be created by providing water cooling pipes, water cooling plates, semiconductor refrigeration components, heating components, and the like.

[0057] In some embodiments, one of the first opening and closing assembly 20 and the second opening and closing assembly 30 is located inside the test cavity Q, and the other is located outside the test cavity Q. Figure 1 In the illustrated embodiment, the first opening and closing assembly 20 is located in the test cavity Q, and the second opening and closing assembly 30 is located outside the test cavity Q. At this time, the first opening and closing assembly 20 and the second opening and closing assembly 30 are arranged in the test cavity Q and outside the test cavity Q, respectively, which facilitates the layout of the two on the box 10.

[0058] Of course, in other embodiments, the first opening and closing assembly 20 and the second opening and closing assembly 30 may also be arranged in the test cavity Q at the same time or outside the test cavity Q at the same time.

[0059] In some embodiments, see Figure 3 The first opening and closing assembly 20 includes two first door bodies 21, and the two first door panels are movably arranged along the box body 10 to open and close the operation window K together.

[0060] The two first doors 21 can have the same or different structures, as long as they can close the operation window K in one state and fully open the operation window K in another state. The trajectory of the first door 21 moving along the box 10 can be a straight trajectory, a curved trajectory, etc.

[0061] At this time, the two first doors 21 cooperate to open and close the operation window K, and the operation window K opens and closes quickly. Moreover, when each first door 21 moves along the box body 10 to open and close the operation window K, the movement process does not occupy too much space, which helps to achieve the compactness of the structure of the test box 100.

[0062] In some embodiments, the two first doors 21 move synchronously in opposite directions in the same direction along the box body 10. When the two first doors 21 approach each other in the same direction, the operation window K can be gradually closed, and when they move away from each other in the same direction, the operation window K can be gradually opened.

[0063] Usually, the two first doors 21 move synchronously in opposite directions along the length direction of the box body 10, and the moving direction is a straight line direction. When the operation window K needs to be opened, the two first doors 21 move synchronously in opposite directions. When the operation window K needs to be closed, the two first doors 21 move synchronously toward each other.

[0064] At this time, the first door body 21 and the second door body 31 move synchronously, which can shorten the distance of the first door body 21 to open and close the operation window K, and the two first door bodies 21 move along the same straight line, which is also convenient for the layout of the box body 10, and the structure of the box body 10 is more compact.

[0065] There are many ways to construct the driving mechanism for driving the two first door bodies 21 to move. For example, the first opening and closing assembly 20 also includes a first driving motor, and each first door body 21 is driven to move linearly by a first driving cylinder 22. Furthermore, a guide rail 23 can be provided on the box body 10, and each first door body 21 moves along the corresponding guide rail 23, and the movement is smoother.

[0066] In some embodiments, see Figure 3 Each first door body 21 has a first position of opening the operation window K and a second position of closing the operation window K on its moving track. In-position sensors are arranged on the box body 10 corresponding to the first position and the second position.

[0067] The in-position sensor can be a light sensor, a proximity switch, an image sensor, etc., which is used to detect whether the first door body 21 has reached the corresponding first position or the second position, so that the first door body 21 can accurately open and close the operation window K, avoiding interference from the first door body 21 when the material transfer robot 200 and the crimping head of the crimping device 300 pass through the operation window K.

[0068] Of course, in other embodiments, the first opening and closing assembly 20 may also be composed of a first door body 21 to realize the opening and closing operation window K.

[0069] In some embodiments, see Figure 1 , Figure 2 , Figures 4 to 6 The second opening and closing assembly 30 includes a second door body 31, which is movably arranged along the box body 10 and can open and close the open area K1 during the movement. The second door body 31 opens and closes the above-mentioned open area K1 of the operation window K during the movement of the second door body 31 along the box body 10, and its movement process does not occupy too much space, and only one second door body 31 opens and closes the open area K1, which helps to achieve the compactness of the structure of the test box 100 and simplify the structure of the test box 100.

[0070] The trajectory of the second door body 31 moving along the box body 10 can be a straight trajectory, a curved trajectory, etc. Specifically, a second driving cylinder 32 can be set on the box body 10, and the second driving cylinder 32 is connected to the second door body 31 and drives the second door body 31 to move. Regarding the driving structure for driving the second door body 31 to move, those skilled in the art can make conventional settings. Figure 4 As shown, the second opening and closing assembly 30 also includes a guide plate 33 and a connecting plate 34, the guide plate 33 is connected to the driving end of the second driving cylinder 32 and the connecting plate 34, the connecting plate 34 is connected to the second door body 31, and the guide plate 33 can move along the outer contour of the second driving cylinder 32 in the driving direction of the second driving cylinder 32 to guide the movement of the second door body 31.

[0071] In some embodiments, reference Figure 4 , and combined with Figure 5 The end surface of the second door body 31 facing the operation window K is constructed as a step surface 31a. When the second door body 31 closes the open area K1, the step surface 31a can adapt and fit with the outer contour shape of the material transfer robot 200.

[0072] In actual application, the open area K1 defined between the material transfer robot 200 and the inner wall of the operating window K may not be a regular shape. When the material transfer robot 200 is located at the operating window K, the step surface 31a of the second door body 31 can match and fit the outer contour of the material transfer robot 200, and can effectively close the open area K1.

[0073] In some embodiments, see Figure 1 , Figure 2 , Figures 4 to 6 The box body 10 includes a box body 11 and a cover plate 12. The box body 11 forms a test cavity Q with one end open. The cover plate 12 covers the open end of the box body 11. The operation window K, the first opening and closing assembly 20 and the second opening and closing assembly 30 are all arranged on the cover plate 12. The air inlet 13 is arranged on the box body 11 and / or the cover plate 12.

[0074] Typically, the box body 11 is a rectangular box, in which a test bench 80 is arranged to support the device to be tested. The cover plate 12 may be a square cover plate 12. The air inlet 13 may be arranged on the cover body or on the box body 11. Typically, the box body 11 is provided with an air inlet 13.

[0075] Generally, the cover plate 12 is arranged on the top side of the box body 11 in the height direction of the test box 100 .

[0076] At this time, the test chamber Q is assembled with a box body 11 and a cover plate 12. Since the operation window K, the first opening and closing component 20 and the second opening and closing component 30 are all arranged on the cover plate 12, in the actual production process, the existing box body 11 structure can be used and only the cover plate 12 can be improved accordingly, and the improvement cost is relatively low.

[0077] In some embodiments, see Figure 1 , Figure 2 , Figures 4 to 6 The crimping device 300 includes a sealing cover 301 and a crimping head (not shown). The crimping head is used to penetrate the operation window K and crimp the device to be tested in the test cavity Q. The sealing cover 301 is used to cover the operation window K when the crimping head crimps the device to be tested. The test box 100 also includes a plurality of arch handles 60 disposed on the cover plate 12. The plurality of arch handles 60 are located outside the test cavity Q and are arranged around the operation window K. The arch handles 60 can support the sealing cover 301 when the crimping head penetrates the operation window K.

[0078] For the introduction of the crimping head and the sealing cover 301, refer to the above description.

[0079] The arch handle 60 is an arched handle, specifically, it can be a semicircular arch, an arcuate arch, a square arch, etc. The arch handle 60 can be arranged around the circumference of the cover plate 12, such as arranged on the four sides of the cover plate 12, or arranged on the two symmetrical sides of the cover plate 12. The arch handle 60 can also be arranged at a position of the cover plate 12 close to the operation window K, as long as it does not interfere with the crimping head of the crimping device 300 passing through the operation window K.
