Description

An integrated circuit testing machine Technical Field

[0001] This application relates to the field of integrated circuit manufacturing technology, and in particular to an integrated circuit testing machine. Background Technology

[0002] Automatic integrated circuit testing machines play a crucial role in the chip industry. They are primarily used to test the functional integrity and quality control of integrated circuits, ensuring that the manufactured integrated circuits meet design requirements.

[0003] Currently, referring to Figures 1 and 2, the integrated circuit automatic testing machine includes an outer casing 30, an inner casing 31, and a resource board 3. The inner casing 31 has a base plate 5 for the resource board 3 to be inserted into. The resource board 3 and the base plate 5 are connected to each other through an interface. The outer periphery of the resource board 3 is covered with a hollow frame. Multiple mounting pieces 32 are arranged vertically on the side of the frame. The mounting pieces 32 have through holes for bolts to pass through. The mounting pieces 32 are installed on the side wall of the inner casing 31 by bolts.

[0004] However, since the outer casing 30 encloses the inner casing 31, when it is necessary to replace the resource board 3, the surrounding panels of the outer casing 30 must be disassembled first, then the inner casing 31 must be removed from the outer casing 30, and then the bolts must be released one by one before the resource board 3 can be removed, which makes the replacement of the resource board 3 quite troublesome. Summary of the Invention

[0005] To improve the convenience of replacing resource boards, this application provides an integrated circuit testing machine.

[0006] The technical solution adopted in this application is as follows.

[0007] An integrated circuit testing machine includes: a test outer casing, a test inner casing, a resource board, and multiple sets of assembly components;

[0008] The inner test basket is installed in the outer test box, and the inner test basket forms a mounting cavity into which the resource board extends; the inner test basket has a bottom plate, which is located in the mounting cavity, and the bottom plate has an interface for the resource board to be inserted; the resource board is surrounded by a hollow protective frame, and the protective frame has a mounting seat along the height direction of the resource board;

[0009] The assembly components are disposed on the inner test basket, and the assembly components correspond to the sides of the enclosure frame; each set of assembly components includes

[0010] A guide seat is connected to the inner test basket and extends along the direction of the resource plate. The mounting seat can fit the guide seat and move along the length of the guide seat.

[0011] The positioning post moves along the direction perpendicular to the height of the guide seat, and the mounting seat has a socket corresponding to the positioning post and for the positioning post to be inserted.

[0012] The pusher is rotatably connected to the guide seat and extends along the length of the guide seat, while abutting against all the positioning pins in the guide seat; and

[0013] A linkage component is movable at one end of the guide seat away from the base plate and can cooperate with the push component to drive the push component to rotate, so that the positioning column can be moved to the first position and the second position by moving the linkage component, and the linkage component has a part located outside the test box;

[0014] When the positioning post is in the first position, it is housed in the guide seat; when the positioning post is in the second position, it is moved out of the guide seat, and at the same time, the positioning post can be inserted into the mounting seat through the insertion hole along the length direction perpendicular to the guide seat.

[0015] By adopting the above technical solution, the integrated circuit testing machine can quickly install and remove resource boards, simplifying the resource board replacement process and improving work efficiency. Specifically, through the cooperation of the guide seat, positioning post, pushing component, and linkage component, the positioning post can be easily moved to the first or second position by moving the linkage component from outside the test enclosure, thereby quickly releasing and locking the resource board and improving the convenience of replacing the resource board.

[0016] Optionally, the inner test basket is provided with a limiting strip, the limiting strip is provided with a plurality of limiting grooves at intervals along its own length direction, and the enclosure frame has a limiting protrusion for insertion into the limiting groove.

[0017] By adopting the above technical solution, the stability and accuracy of the resource board during installation are improved through the cooperation of the limiting strip and the limiting protrusion, and the resource board is less likely to deviate during installation.

[0018] Optionally, the positioning post is magnetically attracted to the pushing member, and the pushing member is alternately provided with a first abutting part and a second abutting part. When the pushing member rotates, the first abutting part and the second abutting part abut against the end of the positioning post away from the outside of the guide seat in sequence.

[0019] When the positioning post abuts against the first abutting part, the positioning post moves to the first position; when the positioning post abuts against the second abutting part, the positioning post moves to the second position.

[0020] By adopting the above technical solution, the positioning column is kept in contact with the pushing component by the magnetic attraction of the pushing component, so that the positioning column can move in conjunction with the pushing component during the rotation.

[0021] Optionally, the guide seat is provided with a first elastic element connected to the positioning post, and the first elastic element always provides the positioning post with an elastic force that pushes against the pushing member in the direction of approaching the pushing member.

[0022] By incorporating a first elastic element, the repositioning capability of the positioning pin is improved, thereby enhancing the reliability and stability of the entire assembly.

[0023] Optionally, the pusher includes a rotating section and a pushing section that extend along the same straight line and are fixedly connected, and the rotating section is cylindrical and rotates in the guide seat, and the first abutting part and the second abutting part are both disposed on the pushing section;

[0024] The linkage includes a movable seat, a stroke column, and an extension handle. The stroke column and the extension handle are both connected to the movable seat. The stroke column abuts into the rotating section. The outer wall of the rotating section has a stroke groove for the stroke column to abut and slide. The stroke groove extends obliquely along the circumference of the rotating section. The extension handle extends away from the movable seat. By pushing and pulling the extension handle, the movable seat and the stroke column can be moved along the axis parallel to the rotating section in the guide seat.

[0025] By adopting the above technical solution, through the cooperation of the stroke column and the stroke groove, the rotating section can be driven to rotate during the up and down movement of the extension handle, thereby driving the push section to rotate.

[0026] Optionally, the top of the test inner basket has a first arc-shaped portion; the top of the enclosure frame has an outer edge for abutting against the top of the test inner basket, the outer edge having a second arc-shaped portion, the outer diameter of the first arc-shaped portion and the outer diameter of the second arc-shaped portion being the same; when the outer edge abuts against the test inner basket, the center of the first arc-shaped portion coincides with the center of the second arc-shaped portion;

[0027] The movable seat includes an outer seat and a rotating shaft. The outer seat moves within the guide seat along its length. One end of the rotating shaft is rotatably connected to the outer seat, and the other end extends out of the outer seat and is connected to the extension handle. The linkage also includes an abutment seat located at the end of the extension handle away from the movable seat. The outer wall of the second arcuate portion has an abutment groove for the abutment seat to abut. The outer seat can move within the guide seat to mutually distant limiting and rotating positions.

[0028] When the outer seat moves in the guide seat to one end away from the outer edge, the outer seat is in the restricted position. At this time, the abutment seat abuts into the abutment groove, and the positioning post moves to the second position. When the outer seat moves in the guide seat to one end close to the outer edge, the outer seat is in the rotation position. The abutment seat leaves the abutment groove, the positioning post moves to the first position, and at this time, the axis of the rotation shaft coincides with the center of the first arc portion. The abutment seat can drive the extension handle to rotate around the axis of the rotation shaft, so that the abutment seat leaves the outer edge and abuts against the first arc portion.

[0029] By adopting the above technical solution, the extension handle rotates in the rotating position, so that when the resource board is unlocked, the abutment can leave the outer edge, allowing the resource board to move upward away from the inner test basket. When the resource board is locked, the abutment can simultaneously press down on the outer edge of the resource board to further improve the locking effect of the resource board.

[0030] Optionally, the guide seat has a second elastic element connected to the outer seat, the second elastic element always providing elastic force to move the outer seat toward the limiting position.

[0031] By adopting the above technical solution, the stability of the abutment seat when it abuts into the abutment groove is improved by using the second elastic element.

[0032] Optionally, the linkage further includes a pull ring disposed on the abutment seat, wherein when the abutment seat abuts into the outer edge, the pull ring is located outside the outer edge.

[0033] By adopting the above technical solution, the pull ring allows operators to directly pull the extension handle from the outside, improving the convenience of operation.

[0034] Optionally, the end of the positioning post away from the pusher is provided with a pointed tip.

[0035] By adopting the above technical solution, the tip makes it easier for the positioning post to enter and lock when inserted into the socket, thus improving the accuracy and efficiency of installation.

[0036] Optionally, the positioning posts are provided on both opposite sides of the pusher.

[0037] By adopting the above technical solution, positioning posts are set on both sides of the pusher, which further enhances the stability and reliability of the resource board during installation and makes it less likely to shift or be damaged due to uneven force on one side.

[0038] In summary, this application includes at least one of the following beneficial effects:

[0039] 1. By pulling the extension handle outside the test enclosure to lock and release the mounting base by moving the positioning post in the test inner basket, the resource board can be quickly disassembled and assembled without separating the test enclosure and the test inner basket, thereby improving the convenience of replacing the resource board.

[0040] 2. During the installation of the resource board, multiple structures are employed to enhance its stability and reliability. For example, the cooperation between the limiting strip and the limiting protrusion makes it less prone to displacement or shaking during installation; the magnetic attraction between the positioning post and the pushing component improves the accuracy of positioning; at the same time, the addition of the first and second elastic components further enhances the stability and reliability of the entire assembly.

[0052] The present application will be further described in detail below with reference to Figures 3-10.

[0053] This application discloses an integrated circuit testing machine. Referring to FIG3, the integrated circuit testing machine includes a test outer casing 1, a test inner frame 2, a resource board 3, and an assembly assembly. The test inner frame 2 is installed in the test outer casing 1, the resource board 3 is installed in the test inner frame 2, and the assembly assembly is used to install the resource board 3 onto the test inner frame 2.

[0054] Referring to Figures 3 and 4, the test outer box 1 is a square box with the opening facing upwards, which includes a square frame 101 and a surrounding panel 102 that is detachably connected to the frame 101 by bolts.

[0055] Referring to Figures 4 and 5, the test inner basket 2 is square, including a base 201 and side plates 202. The base 201 is a hollow square base, which is installed at the bottom of the frame 101 by bolts. There are two side plates 202, which are respectively installed on opposite sides of the upper surface of the base 201. The base 201 and the side plates 202 together form the mounting cavity 4. The test inner basket 2 has a bottom plate 5, which is square. The bottom plate 5 is fixed to the upper surface of the base 201 and located between the two side plates 202. The bottom plate 5 has an array of interfaces 6 for the resource board 3 to be inserted and electrically connected to the resource board 3.

[0056] Referring to Figures 5 and 6, the resource board 3 has multiple circuit components (not shown in the figures). The resource board 3 is surrounded by a square-shaped protective frame 7, which does not contact the circuit components on the resource board 3. The resource board 3 has interfaces 6 extending out of the protective frame 7 at both the bottom and top. The bottom interface 6 is used to plug into the bottom interface 6 of the base plate 5, and the top interface 6 is used to connect to an external power supply.

[0057] Referring to Figure 6, multiple square-shaped mounting seats 8 are arranged in an array on both sides of the enclosure frame 7 that are far apart from each other. The surface of the mounting seat 8 is parallel to the surface of the resource board 3, and each mounting seat 8 has an insertion hole 33 that passes through both opposite sides of the mounting seat 8. The mounting seats 8 on each side of the resource board 3 are arranged in multiple rows evenly spaced vertically along the resource board 3, and in two columns horizontally, with the mounting seats 8 in the two columns corresponding one-to-one and having gaps between them. In this embodiment, there are three rows of mounting seats 8; in other embodiments, there may be four or five rows of mounting seats 8.

[0058] Referring to Figure 4, when multiple resource boards 3 are installed into the test inner basket 2, the multiple resource boards 3 are distributed perpendicular to the two side panels 202. Each resource board 3 corresponds to two sets of assembly components, which are respectively installed on the opposite surfaces of the two side panels 202. After the resource boards 3 are inserted into the base plate 5, the two sets of assembly components corresponding to the resource boards 3 are respectively positioned on opposite sides of the enclosure frame 7, and these two sets of assembly components limit the opposite sides of the enclosure frame 7.

[0059] Referring to Figures 4 and 7, each assembly component specifically includes a guide seat 9, a positioning post 10, a pushing component 11, and a linkage component 12. Referring to Figure 5, the guide seat 9 is a long strip extending vertically, and one outer wall of the guide seat 9 is fixed to the side of the side plate 202 facing the mounting cavity 4. The width of the guide seat 9 is consistent with the gap between the two opposite mounting seats 8, and the width between the opposite surfaces of the two side plates 202 relative to the guide seat 9 is consistent with the distance between the opposite sides of the enclosure frame 7. The resource plate 3 is fitted onto the guide seat 9 via the mounting seat 8 and slides up and down relative to the guide seat 9 to guide the movement of the resource plate 3 within the test inner basket 2, enabling the resource plate 3 to align with the corresponding interface 6 on the base plate 5 and insert downwards into the interface 6.

[0060] Referring to Figures 7 and 8, multiple sets of positioning posts 10 are installed in the guide seat 9 and arranged along the length of the guide seat 9. The number of sets of positioning posts 10 is consistent with the number of rows of mounting seats 8, and each set of positioning posts 10 corresponds to each row of mounting seats 8. Therefore, in this embodiment, there are three sets of positioning posts 10 along the guide seat 9. The positioning posts 10 are cylindrical, and the size of the insertion hole 33 is adapted to the positioning posts 10. There are two positioning posts 10 in each set. The distribution direction, movement direction, and extension length direction of the two positioning posts 10 are all parallel to the distribution direction of the resource plate 3. A sliding groove 26 is provided on the guide seat 9 for the positioning posts 10 to slide and guide the positioning posts 10. The sliding groove 26 extends to the outside of the guide seat 9.

[0061] Referring to Figures 7 and 8, the pusher 11 is rotatably connected to the guide seat 9, and is simultaneously located between two opposing positioning posts 10 in each group. The pusher 11 includes a rotating segment 111 and a pushing segment 112 arranged sequentially. The rotating segment 111 is cylindrical, and the pushing segment 112 is elliptical. The rotating segment 111 and the pushing segment 112 are coaxially fixed, and their axes are parallel to the length extension direction of the guide seat 9. The top end of the rotating segment 111 is rotatably connected to the top of the guide seat 9, and the bottom end of the pushing segment 112 is rotatably connected to the bottom of the guide seat 9. The guide seat 9 has a rotating cavity 27 that allows the pushing segment 112 to rotate, and the pushing segment 112 is simultaneously opposite to each positioning post 10 in the same guide seat 9, while the rotating segment 111 is away from the positioning post 10.

[0062] The sliding groove 26 is connected to the rotating cavity 27, and the pushing section 112 is magnetic. The two positioning posts 10 in the same group abut against and are magnetically attracted to the opposite outer walls of the pushing section 112 at their closest points. The part corresponding to the short side of the cross-section of the pushing section 112 is the first abutting part 16, and the part corresponding to the long side of the cross-section of the pushing section 112 is the second abutting part 17.

[0063] When the pushing section 112 rotates to the point where the first abutting part 16 abuts against the positioning post 10, the positioning post 10 moves to the first position, at which point the positioning post 10 is completely retracted into the guide seat 9. When the pushing section 112 rotates to the point where the second abutting part 17 abuts against the positioning post 10, the positioning post 10 moves to the second position, at which point the positioning post 10 is pushed to the point where the end away from the pushing section 112 protrudes from the guide seat 9.

[0064] Referring to Figures 4 and 8, when the resource plate 3 and the base plate 5 are connected by the interface 6, the position of the mounting seat 8 corresponds one-to-one with the sliding groove 26. At this time, rotating the push section 112 moves the positioning pin 10 from the first position to the second position, so that all the positioning pins 10 in the guide seat 9 are simultaneously inserted into the corresponding mounting seat 8 to position the mounting seat 8 and restrict the movement of the mounting seat 8.

[0065] Referring to Figures 7 and 8, a first elastic element 18, which is a spring, is further installed in the guide seat 9. One end of the first elastic element 18 is connected to the guide seat 9, and the other end is connected to the positioning post 10 through a connecting piece to provide elastic force for the positioning post 10 to move inward into the guide seat 9, thereby further improving the clamping effect between the positioning post 10 and the pushing section 112. In addition, the end of the positioning post 10 away from the pushing section 112 forms a tip 25 that gradually decreases in the direction away from the pushing section 112, so as to guide the positioning post 10 when it is inserted into the mounting seat 8. When the positioning post 10 is inserted into the mounting seat 8, a portion of the cylindrical section of the positioning post 10 is inserted into the mounting seat 8.

[0066] 0043. Referring to Figures 5 and 8, the linkage 12 is installed on the top of the guide seat 9 and is used to link with the rotating section 111 to drive the rotating section 111 to rotate, thereby realizing the adjustment of the rotation position of the pushing section 112. Referring to Figure 9, the top of the side plate 202 has a first arcuate portion 20, which is arcuate away from the outer periphery of the guide seat 9, and the top surface of the first arcuate portion 20 is horizontal. The top surface of the guide seat 9 is flush with the top surface of the first arcuate portion 20, and the center of the first arcuate portion 20 is located in the guide seat 9. The top of the enclosure frame 7 extends along the width direction of the resource plate 3 with an outer edge 21 protruding from the side of the enclosure frame 7. The outer edge 21 forms a second arcuate portion 22 with an arcuate outer periphery, and the bottom surface of the outer edge 21 is horizontal.

[0067] The outer diameters of the arc portion in the first arc portion 20 and the arc portion in the second arc portion 22 are the same, and both the first arc portion 20 and the second arc portion 22 are located on the upper side of the top of the outer casing 30. When the resource plate 3 and the bottom plate 5 are connected by the interface 6, the bottom surface of the outer edge 21 abuts against the top surface of the side plate 202, and the centers of the first arc portion 20 and the second arc portion 22 coincide. At the same time, the first arc portion 20 and the second arc portion 22 together form a continuous quarter arc.

[0068] Referring to Figures 8, 9, and 10, the linkage 12 includes a movable seat 121, a stroke column 122, an extension handle 123, an abutment seat 124, and a pull ring 125. The movable seat 121 includes an outer seat 1211 and a rotating shaft 1212. The outer seat 1211 is block-shaped and moves along the length of the guide seat 9 at the top of the guide seat 9. The guide seat 9 has a guide groove 28 for sliding and guiding the movement of the outer seat 1211. The rotating shaft 1212 is rotatably connected to one side of the outer seat 1211. The axis of the rotating shaft 1212 is parallel to the distribution direction of the resource plates 3, and one end of the rotating shaft 1212 extends out of the outer seat 1211. The outer seat 1211 and the rotating shaft 1212 move up and down together in the guide seat 9. When the outer seat 1211 moves to the bottom of the guide groove 28, it is in the restricted position. When the outer seat 1211 moves to the top of the guide groove 28, it is in the rotating position. At this time, the axis of the rotating shaft 1212 coincides with the center of the first arc portion 20.

[0069] The stroke column 122 is fixed to the outer seat 1211 on the side away from the rotating shaft 1212 and extends to cooperate with the rotating section 111. The outer peripheral wall of the rotating section 111 is inclined and has a stroke groove 19 for the stroke column 122 to abut and slide. When the movable seat 121 moves up and down, it drives the stroke column 122 to move up and down together, so that the stroke column 122 slides in the stroke groove 19, thereby driving the rotating section 111 to rotate. The maximum rotation angle of the rotating section 111 is 90°.

[0070] The extension handle 123 extends cylindrically along the axis of the vertical rotation shaft 1212. One end of the extension handle 123 is fixedly connected to the portion of the rotation shaft 1212 that extends out of the movable seat 121, and the distance from the end of the extension handle 123 away from the axis of the rotation shaft 1212 is the same as the outer diameter of the first arc portion 20. At the same time, with the center of the first arc portion 20 as the midpoint, the first arc portion 20, the guide seat 9, and the second arc portion 22 are all provided with relief grooves 29 for the extension handle 123 to rotate along the axis of the rotation shaft 1212, and the range of rotation that the extension handle 123 can take is a quarter arc formed by the first arc portion 20 and the second arc portion 22.

[0071] The abutment seat 124 is cylindrical and coaxially fixed to the end of the extension handle 123 away from the rotation shaft 1212, and the outer diameter of the abutment seat 124 is larger than the outer diameter of the extension handle 123. The upper surface of the second arc portion 22 is provided with an abutment groove 23 for the abutment seat 124 to abut into. The pull ring 125 is fixed to the end of the abutment seat 124 away from the extension handle 123.

[0072] When positioning the resource board 3, the outer seat 1211 is in the restricted position, the extension handle 123 extends vertically, and the abutment seat 124 abuts into the abutment groove 23 vertically. At this time, the pull ring 125 is outside the outer edge 21, and the pushing section 112 pushes the positioning post 10 to the second position so that the mounting seat 8 into which the positioning post 10 is inserted positions the resource board 3.

[0073] When resource plate 3 needs to be replaced, pull the extension handle 123 upward to disengage it from the abutment groove 23, causing the travel post 122 to slide from the bottom of the travel groove 19 to the top of the travel groove 19. The pushing section 112 pushes the positioning post 10 to the first position, causing the positioning post 10 to leave the mounting base 8. Then, rotate the extension handle 123 outward and drive the rotating shaft 1212 to rotate together. After the abutment seat 124 passes the second arc portion 22, it abuts against the first arc portion 20, so that both the abutment seat 124 and the extension handle 123 leave the outer edge 21. At this time, pulling the resource plate 3 upward will allow the resource plate 3 to be removed upward. During the rotation, the abutment seat 124 abuts against the second arc portion 22 when it passes the second arc portion 22, and abuts against the first arc portion 20 when it passes the first arc portion 20, so that the outer base 1211 is always in the rotating position.

[0074] Furthermore, a second elastic element 24 is installed at the bottom end of the guide seat 9 in the guide groove 28. The second elastic element 24 is a spring, and the bottom end of the second elastic element 24 is connected to the guide seat 9, while the top end is connected to the bottom surface of the outer seat 1211. The second elastic element 24 always provides the outer seat 1211 with a downward elastic force, thereby improving the stability of the abutment seat 124 after it abuts into the abutment groove 23.

[0075] Referring to Figures 5 and 6, two elongated limiting strips 13 are fixed to the upper surface of the base 201 of the inner test basket 2. The length of the limiting strips 13 extends parallel to the distribution direction of the resource plates 3. The two limiting strips 13 are located in the mounting cavity 4 and on opposite sides of the base plate 5. Each limiting strip 13 has multiple limiting grooves 14 evenly spaced along its length on its upper surface, and the limiting grooves 14 on the two limiting strips 13 correspond one-to-one. Limiting protrusions 15 are fixed to the two mutually distant sides of the bottom of the enclosure frame 7 of the resource plate 3. The distance between two limiting protrusions 15 is the same as the distance between two opposite limiting grooves 14. The limiting protrusions 15 extend downward beyond the interface 6 of the resource plate 3 and are used to insert into the limiting grooves 14.

[0076] During the process of the resource board 3 moving downward in the test inner basket 2, the resource board 3 is first inserted into the two limit strips 13 through the cooperation of the limit protrusion 15 and the limit groove 14, and then inserted into the base plate 5 through the interface 6 to further guide the insertion and installation of the resource board 3.

[0077] The part of the side plate 202 that does not mate with the guide seat 9 is hollowed out to improve the heat dissipation effect during the test and to allow a fan (not shown in the figure) to be installed on the outside of the side plate 202. Through holes (not shown in the figure) are opened on the enclosure plate 102 to further improve the heat dissipation effect.

[0078] The implementation principle of the integrated circuit testing machine of this application is as follows: First, the abutment seat 124 drives the extension handle 123 to rotate until it abuts against the first arc portion 20 of the side plate 202. Then, the resource board 3 to be replaced is pulled out upwards, and the new resource board 3 is inserted downwards, so that the outer edge 21 of the resource board 3 abuts against the upper surface of the first arc portion 20. Then, the abutment seat 124 drives the extension portion to rotate vertically, so that the abutment seat 124 is opposite to the abutment groove 23 of the second arc portion 22. Then, the abutment seat 124 is moved downwards until it abuts into the abutment groove 23. Through the cooperation of the stroke portion and the stroke groove 19, the push section 112 is driven to rotate, so that the push section 112 pushes the positioning post 10 out of the guide seat 9 and inserts it into the corresponding mounting seat 8, thereby positioning the resource board 3.

[0079] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
