Description

Technical Field

[0002] Semiconductor products, such as chips, need to be electrically tested after production to ensure the yield rate after leaving the factory. Existing testing devices usually include a socket mechanism and an electrical testing mechanism. The socket mechanism is used to accommodate and fix the product, and the electrical testing mechanism is suitable for being electrically connected to the socket mechanism to perform electrical testing on the product. For some photosensitive chips, the photosensitive area of ​​the product needs to be illuminated during the test process in order to verify the various functions of the product. For example, Chinese utility model patent CN219016505U discloses a photosensitive chip test socket for being electrically connected to an electrical testing mechanism, which can accommodate and fix the product, and the socket is provided with a light-emitting component for illuminating the photosensitive area of ​​the product.

[0003] In actual production, in order to improve the degree of automation of testing, a number of socket mechanisms are usually set up, and the transmission is connected to the conveying structure. The electric measuring mechanism is located on the conveying path of the conveying structure. When the conveying structure drives the socket mechanism to flow through the electric measuring mechanism, the electric measuring mechanism can be connected to the socket mechanism. However, conventional test sockets with light-emitting parts have complex structures and heavy weights. A single test socket is expensive. Large quantities of them are set up on the conveying structure, which greatly increases the production cost. In addition, the load requirements for the conveying structure are high, and the cost will be further increased.

It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0033] See also Figures 1 to 4 As shown, an electrical testing device 1000 corresponding to a preferred embodiment of the present invention includes: a mounting frame 100; an electrical measuring mechanism 200, which can be lifted and lowered on the mounting frame 100 in a vertical direction; a light source mechanism 300, which can be lifted and lowered on the mounting frame 100 in a vertical direction and is arranged opposite to the electrical measuring mechanism 200 in the vertical direction; a connecting rod mechanism 400, which is respectively connected to the electrical measuring mechanism 200 and the light source mechanism 300; a connecting rod driving member 500, which is arranged on the mounting frame 100 and is transmission-connected to the connecting rod mechanism 400; wherein a test gap 600 for accommodating a product is formed between the electrical measuring mechanism 200 and the light source mechanism 300, and the electrical measuring mechanism 200 and the light source mechanism 300 are suitable for moving toward each other in the vertical direction to a test state driven by the connecting rod mechanism 400 to illuminate and test the product, or moving back to back in the vertical direction to a separation state to allow the product to enter and exit.

[0034] The present invention arranges an electric measuring mechanism 200 and a light source mechanism 300 which can be lifted and lowered in a vertical direction on a mounting frame 100. When a product flows through a test gap 600 between the electric measuring mechanism 200 and the light source mechanism 300, the electric measuring mechanism 200 and the light source mechanism 300 can move toward each other in the vertical direction to a test state to illuminate and test the product, or move back to back in the vertical direction to a separation state to facilitate the entry and exit of the product. The electric testing device 1000 integrates both illumination and testing functions, which can meet the needs of photosensitivity testing while effectively reducing the production cost of the testing system. In addition, by setting a connecting rod mechanism 400 and a connecting rod driving member 500 which is transmission-connected to the connecting rod mechanism 400, the connecting rod mechanism 400 is respectively connected to the electric measuring mechanism 200 and the light source mechanism 300. The connecting rod mechanism 400 can drive the electric measuring mechanism 200 and the light source mechanism 300 to move toward or away from each other in the vertical direction under the drive of the connecting rod driving member 500. The electric measuring mechanism 200 and the light source mechanism 300 have high synchronization during the movement, ensuring that the two are accurately switched to the test state or the separation state, and can avoid setting up more driving members, thereby further reducing costs.

[0035] Furthermore, the electric measuring mechanism 200 is located below the light source mechanism 300, and the photosensitive area of ​​the product is arranged upward. When the electric measuring mechanism 200 and the light source mechanism 300 move toward each other, the electric measuring mechanism 200 is suitable for approaching the product upward and being electrically connected to the product, and the light source mechanism 300 is suitable for approaching the product downward and covering the photosensitive area of ​​the product.

[0036] Furthermore, the electrical testing mechanism 200 includes a first lifting seat 210, an electrical testing board 220 and a connector 230. A slide rail structure arranged along the vertical direction is provided between the first lifting seat 210 and the mounting frame 100, so that the first lifting seat 210 is slidably connected to the mounting frame 100. The electrical testing board 220 is specifically a PCB board, which is fixed on the first lifting seat 210. The board surface of the electrical testing board 220 is perpendicular to the vertical direction. The upper board surface of the electrical testing board 220 is provided with an electrical connection element 221 for electrically connecting to the product. The connector 230 is fixed on the electrical testing board 220 and electrically connected to the electrical testing board 220. The connector 230 is electrically connected to an external testing device through a cable to obtain various test data of the product.

[0037] In this embodiment, the first lifting seat 210 includes a lifting seat body 211, a support block 212, a mounting block 213 and a lining plate 214. The lifting seat body 211 is slidably connected to the mounting frame 100, the bottom of the support block 212 is detachably fixed to the lifting seat body 211 by a screw, and the mounting block 213 is detachably fixed to the top of the support block 212 by a screw. The lining plate 214 is fixed to the top of the support block 212, and the electric test board 220 is installed on the lining plate 214.

[0038] By adopting the above structure, it is easy to disassemble, assemble and replace the electric test board 220, and by replacing the support blocks 212 of different heights, the height of the electric test board 220 can be adjusted to match the product. Preferably, the lifting seat body 211 and the mounting block 213 are both provided with pillars 215, and a first spring 216 is connected between the two pillars 215. The first spring 216 can provide a force to make the support block 212 and the mounting block 213 press against the lifting seat body 211, thereby improving the tightness of the connection.

[0039] Further, the light source mechanism 300 includes a second lifting seat 310 and a light source 320. The second lifting seat 310 is located above the first lifting seat 210, and the test gap 600 is formed between the bottom of the second lifting seat 310 and the top of the electrical test board 220. A slide rail structure arranged along the vertical direction is provided between the second lifting seat 310 and the mounting frame 100, so that the second lifting seat 310 is slidably connected with the mounting frame 100. The second lifting seat 310 is provided with a light outlet hole 311 through the vertical direction, and the light source 320 is fixed to the top of the second lifting seat 310, and the irradiation end of the light source 320 is connected to the top of the light outlet hole 311. The bottom of the light outlet hole 311 is suitable for covering the photosensitive area of ​​the product, and the light emitted by the irradiation end of the light source 320 can be emitted to the photosensitive area of ​​the product through the light outlet hole 311, so that the photosensitive area of ​​the product can be separated from the outside during the test process, so as to avoid the product from being disturbed by external light and improve the test accuracy.

[0040] Further, the connecting rod mechanism 400 is located below the electric measuring mechanism 200, and includes a rotating shaft 410, a lever 420, a first connecting rod 430, and a second connecting rod 440. The rotating shaft 410 is rotatably arranged on the mounting frame 100, the axis of the rotating shaft 410 is parallel to the horizontal direction, and the lever 420 is suitable for synchronously rotating with the rotating shaft 410. The two ends of the first connecting rod 430 are respectively hinged to one end of the lever 420 and the electric measuring mechanism 200, and the two ends of the second connecting rod 440 are respectively hinged to the other end of the lever 420 and the light source mechanism 300. The connecting rod driving member 500 is a rotating motor arranged on the mounting frame 100, and its output end is connected to the rotating shaft 410 to drive the rotating shaft 410 to rotate. The rotating shaft 410 can drive the lever 420 to rotate synchronously. One end of the lever 420 rotates downward and the other end rotates upward, so that one of the first connecting rod 430 and the second connecting rod 440 is pushed upward and the other is pulled downward. The electrical measuring mechanism 200 and the light source mechanism 300 can move toward or away from each other in response to the push and pull of the first connecting rod 430 and the second connecting rod 440.

[0041] Preferably, the first lifting seat 210 is provided with a first hinge 240 for being hinged to the connecting rod mechanism 400, and the second lifting seat 310 is provided with a second hinge 330 for being hinged to the connecting rod mechanism 400. The first hinge 240 is specifically located on the lifting seat body 211 and extends downward from the bottom of the lifting seat body 211, and the second hinge 330 extends downward from the bottom of the second lifting seat 310. The first hinge 240 can be integrally formed with the first lifting seat 210, or they can be assembled together after being formed separately; the second hinge 330 can be integrally formed with the second lifting seat 310, or they can be assembled together after being formed separately.

[0042] In one embodiment, the lever 420 is directly fixedly sleeved on the rotating shaft 410, so that the overall structure of the connecting rod mechanism 400 is simple and the cost is low. The lever 420 includes a rod-shaped lever body 421, the middle part of the lever body 421 is fixedly sleeved outside the rotating shaft 410, and both ends extend along the radial direction of the rotating shaft 410. Both ends of the lever body 421 extend toward the first lifting seat 210 and / or the second lifting seat 310 to form a first hinge part 422 and a second hinge part 423 respectively. When the lever body 421 rotates to a horizontal position, the extension direction of the first hinge part 422 and the second hinge part 423 is parallel to the vertical direction, and the first hinge part 422 is correspondingly arranged directly below the first hinge 240, and the second hinge part 423 is correspondingly arranged directly below the second hinge 330. Both ends of the first link 430 are hinged between the first hinge 240 and the first hinge portion 422, and both ends of the second link 440 are hinged between the second hinge 330 and the second hinge portion 423. When the lever 420 is rotated clockwise, it can push the first link 430 upward and pull the second link 440 downward, so that the electric measuring mechanism 200 and the light source mechanism 300 move toward each other to a testing state. When the lever 420 is rotated counterclockwise, it can pull the first link 430 downward and push the second link 440 upward, so that the electric measuring mechanism 200 and the light source mechanism 300 move away from each other to a separation state.

[0043] However, the above structure has relatively poor synchronization, is difficult to control accurately, and occupies a large space. Figures 5 to 7 As shown, the connecting rod mechanism 400 further includes a rotating member 450 and a cam 460. The rotating member 450 may be a shaft, a cam bearing follower, etc., which is supported between the mounting frame 100 and the lever 420 so that the lever 420 can rotate relative to the mounting frame 100. The axis of the rotating member 450 is parallel to the axis of the rotating shaft 410. The cam 460 is fixedly sleeved on the rotating shaft 410 and is in transmission connection with the electric measuring mechanism 200. The lever 420 rotates in response to the rotation of the cam 460.

[0044] Specifically, the cam 460 is provided with a first guide hole 461 along the axial direction of the rotating shaft 410 and / or the rotating member 450. The first guide hole 461 is an arc-shaped hole extending along the rotation direction of the cam 460. The connecting rod mechanism 400 includes a first follower 470 arranged on the first lifting seat 210. The first follower 470 is a cam bearing follower, which is at least partially embedded in the first guide hole 461 and can roll along the extension direction of the first guide hole 461.

[0045] When the cam 460 is rotated clockwise, the first guide hole 461 is suitable for pushing the first follower 470 upward to drive the first lifting seat 210 to move upward. At the same time, the first connecting rod 430 pulls the lever 420 upward under the drive of the first lifting seat 210 to make the lever 420 rotate clockwise, and the second lifting seat 310 moves downward in response to the pulling of the second connecting rod 440, so that the electric measuring mechanism 200 and the light source mechanism 300 move toward each other to the testing state; when the cam 460 is rotated counterclockwise, the first guide hole 461 is suitable for pulling the first follower 470 downward to drive the first lifting seat 210 to move downward. At the same time, the first connecting rod 430 pushes the lever 420 downward under the drive of the first lifting seat 210 to make the lever 420 rotate counterclockwise, and the second lifting seat 310 moves upward in response to the pushing of the second connecting rod 440, so that the electric measuring mechanism 200 and the light source mechanism 300 move back to back to the separation state. By adopting the above structure, the connecting rod mechanism 400 has a compact structure and is suitable for applications with limited space. The electric measuring mechanism 200 and the light source mechanism 300 are more stable and reliable during movement, and have high synchronization.

[0046] In addition, refer to Figure 8 and Fig. 9As shown, the present invention further provides a testing system, including a turntable device 2000 and the aforementioned electrical testing device 1000 . The turntable device 2000 includes a turntable 700 and a plurality of socket mechanisms 800 for accommodating products. The plurality of socket mechanisms 800 are evenly distributed on the turntable 700 along the circumference of the turntable 700. The turntable 700 has a loading and unloading station and a testing station. The turntable 700 is suitable for driving the socket mechanism 800 to move to the loading and unloading station so that an operator or an automatic handling structure can load the product to be tested into the socket mechanism 800, or move the tested product out of the socket mechanism 800. The electrical testing device 1000 is arranged at the testing station. The turntable 700 is suitable for driving the socket mechanism 800 to move to the testing station so that the socket mechanism 800 is in the testing gap 600. The electrical testing mechanism 200 and the light source mechanism 300 can move toward each other to the testing state. The electrical testing mechanism 200 and the light source mechanism 300 are suitable for being connected to the socket mechanism 800 to realize electrical testing of the product on the socket mechanism 800. Preferably, there are multiple test stations and multiple electrical testing devices 1000, which correspond one to one with the test stations. Driven by the turntable 700, multiple socket mechanisms 800 can be transferred to different test stations in sequence, so that multiple products can be electrically tested at the same time, thereby improving test efficiency.

[0047] Further, refer to Figures 10 to 12 As shown, the socket mechanism 800 includes a socket 810, which is recessed from the top to form a receiving groove 811. The inner contour of the receiving groove 811 is adapted to the outer contour of the product. The product can be adsorbed and positioned in the receiving groove 811 and electrically connected to the socket 810. The bottom of the receiving groove 811 is provided with an adsorption hole, which is connected to the external vacuum generating structure to provide adsorption force to the receiving groove 811. The bottom of the product is adsorbed on the bottom of the receiving groove 811, and the photosensitive area is arranged upward. When the electric measuring mechanism 200 and the light source mechanism 300 are in the test state, the electric measuring mechanism 200 is suitable for electrically plugging with the bottom of the socket 810, and the light source mechanism 300 is sealed on the notch of the receiving groove 811, and is suitable for emitting light from the notch of the receiving groove 811 to the photosensitive area of ​​the product.

[0048] Specifically, the bottom of the socket 810 is provided with a connection hole corresponding to the electrical connection element 221 of the electrical test board 220, and the electrical connection element 221 is adapted to be inserted upward into the connection hole of the socket 810 under the drive of the electrical test board 220. The bottom of the second lifting seat 310 is parallel to the top of the socket 810, and during the downward movement of the second lifting seat 310, the bottom end of the light emitting hole 311 is sealed on the notch of the receiving groove 811, so that light can be emitted into the receiving groove 811 through the light emitting hole 311.

[0049] However, when the above structure is adopted, the product may fly out of the receiving groove 811 under the action of centrifugal force during the high-speed rotation of the turntable 700. As a preferred embodiment, the socket mechanism 800 includes a base 820, a cover assembly 830 and a transmission assembly 840. The base 820 is arranged on the turntable 700, and the socket 810 is arranged on the base 820. The cover assembly 830 is arranged on the base 820, and the cover assembly 830 can be moved in the horizontal direction to a closed state to cover the notch of the receiving groove 811, or moved to an open state to open the notch of the receiving groove 811. The transmission assembly 840 is connected to the cover assembly 830. The turntable device 2000 also includes a switching mechanism 900 arranged at the loading and unloading station of the turntable 700. The switching mechanism 900 is suitable for approaching and pushing the transmission assembly 840. The cover assembly 830 can be switched to an open state under the drive of the transmission assembly 840, and when the switching mechanism 900 is away from the transmission assembly 840, the transmission assembly 840 is suitable for resetting and driving the cover assembly 830 to switch to a closed state.

[0050] By adopting the above structure, when the socket mechanism 800 moves to the loading and unloading station, the switching mechanism 900 can act on the transmission assembly 840 to switch the cover assembly 830 to an open state to avoid hindering the taking and placing of the product. When the switching mechanism 900 does not act on the transmission assembly 840, the transmission assembly 840 can be reset to switch the cover assembly 830 to a closed state, thereby preventing the product from flying out of the receiving groove 811 when the product is transferred. In addition, the switching mechanism 900 does not need to be set on the turntable 700, which reduces the burden on the turntable 700, and only one needs to be set, which simplifies the structure of the turntable device 2000 and increases the service life of the turntable 700.

[0051] Specifically, the turntable 700 is recessed inward from its outer peripheral side to form a first mounting groove 710, and the first mounting groove 710 is vertically penetrated to the top and bottom of the turntable 700. The base 820 is fixedly embedded in the first mounting groove 710. There are multiple first mounting grooves 710, and they correspond to the base 820 one by one. The base 820 is penetrated with a first mounting hole 821 in the vertical direction, and the socket 810 is fixed in the first mounting hole 821 to prevent the base 820 from blocking the top and bottom of the socket 810. The base 820 is recessed inward from its top surface in the vertical direction to form a second mounting groove 822, and the cover assembly 830 is installed in the second mounting groove 822. The base 820 is penetrated with a second mounting hole 823 in the vertical direction, and the transmission assembly 840 can be installed in the second mounting hole 823 in a vertically movable manner.

[0052] The length direction of the base 820 is parallel to the recessed direction of the first mounting groove 710, and the first mounting hole 821, the second mounting groove 822 and the second mounting hole 823 are arranged side by side along the length direction of the base 820, and the first mounting hole 821 is close to the slot mouth of the first mounting groove 710, the second mounting hole 823 is close to the bottom of the first mounting groove 710, and the second mounting groove 822 is located between the first mounting hole 821 and the second mounting hole 823.

[0053] Further, the cover plate assembly 830 includes a cover plate 831 and a connecting column 832, the two ends of the connecting column 832 are fixed to the two opposite inner walls of the second mounting groove 822, and the cover plate 831 is sleeved outside the connecting column 832 and can slide along the connecting column 832. In this embodiment, the axial direction of the connecting column 832 is parallel to the width direction of the base 820, the cover plate 831 is received in the second mounting groove 822, and sleeved outside the connecting column 832, and the cover plate 831 partially extends out of the second mounting groove 822 to form a cover portion, which is located above the socket 810, and the cover portion is suitable for sliding along the axial direction of the connecting column 832 to cover or open the notch of the receiving groove 811.

[0054] Preferably, there are two cover plates 831, which are arranged side by side along the width direction of the base 820. The two cover plates 831 are adapted to move toward each other under the drive of the transmission assembly 840 to cover the receiving slot 811, or move away from each other to open the receiving slot 811. By adopting the above structure, the moving path of a single cover plate 831 can be reduced, and the opening and closing efficiency can be improved.

[0055] However, when the cover 831 is in a closed state, it will also block the photosensitive area of ​​the product, making it difficult for the light source mechanism 300 to illuminate the photosensitive area of ​​the product. As a preferred embodiment, the cover 831 is provided with a evacuation portion 8311 in the vertical direction, and the evacuation portion 8311 can evade the photosensitive area of ​​the product, and the product will not escape from the receiving groove 811 from the evacuation portion 8311. The light source mechanism 300 in the test state can be sealed on the top of the evacuation portion 8311, and the light from the evacuation portion 8311 can be directed to the photosensitive area of ​​the product.

[0056] Further, the transmission assembly 840 includes a transmission plate 841, a second follower 842 and a second spring 843. The transmission plate 841 can be received in the second mounting hole 823 in a vertically movable manner. The transmission plate 841 is provided with a second guide hole 8411 along the length direction of the base 820. The number of the second guide holes 8411 is two, and they correspond to the cover plate 831 one by one. The second guide hole 8411 is a strip hole. The two second guide holes 8411 are arranged in an eight-shaped shape. The distance between the upper ends of the two second guide holes 8411 is smaller than the distance between the lower ends. A notch 824 is provided between the second mounting groove 822 and the second mounting hole 823. The second follower 842 is fixed to the cover plate 831 and at least partially embedded in the second guide hole 8411 through the notch 824. The second follower 842 has the same structure as the first follower 470. The number of the second follower 842 is two, and they correspond to the cover plate 831 and / or the second guide hole 8411 one by one. The transmission plate 841 has a convex portion 8412 opposite to the bottom of the base 820. The expansion and contraction direction of the second spring 843 is parallel to the vertical direction. The second spring 843 is supported between the bottom of the base 820 and the convex portion 8412. The second spring 843 is suitable for providing a force to drive the transmission plate 841 to move downward, and to make the second follower 842 abut against the upper end of the second guide hole 8411. The switching mechanism 900 is located below the rotating disk 700, which is suitable for lifting the transmission plate 841 so that the second guide hole 8411 can rise to drive the two cover plates 831 to move back to the open state, and when the switching mechanism 900 is lowered, the second guide hole 8411 is suitable for descending under the rebound action of the second spring 843 to drive the cover plates 831 to move toward each other to the closed state.

[0057] Further, the switching mechanism 900 includes a mounting seat 910, a lifting driving member 920 and a third follower 930. The lifting driving member 920 is disposed on the mounting seat 910. The lifting driving member 920 is specifically a linear cylinder arranged along the vertical direction. A connecting block 940 is fixed to the output end of the lifting driving member 920. The third follower 930 is mounted on the connecting block 940. The structure of the third follower 930 is the same as that of the second follower 842. It corresponds to the bottom of the transmission plate 841. The lifting driving member 920 is suitable for driving the third follower 930 to rise to lift the transmission plate 841.

[0058] The working process of the test system of the present invention is as follows: the switching mechanism 900 lifts the transmission assembly 840 of the socket mechanism 800 at the loading and unloading station, so that the cover assembly 830 of the socket mechanism 800 is in an open state, and then the product to be tested is loaded into the socket 810, and then the switching mechanism 900 is reset downward, so that the cover assembly 830 is sealed above the product; the turntable 700 drives the socket mechanism 800 to move to the test station, so that the socket mechanism 800 is in the test gap 600, and then the connecting rod driving member 500 drives the electric measuring mechanism 200 and the light source mechanism 300 move toward each other to the testing state, the electric test board 220 is electrically connected to the bottom of the socket 810, the second lifting seat 310 is sealed on the avoidance portion 8311 of the cover assembly 830, and the light emitted by the light source 320 can be emitted to the photosensitive area of ​​the product through the light outlet hole 311 and the avoidance portion 8311, so that the product can undergo various tests; after the test is completed, the turntable 700 drives the socket mechanism 800 to flow back to the loading and unloading station, and the switching mechanism 900 lifts the transmission assembly 840 again to open the cover assembly 830, so as to remove the tested product from the socket 810.
