Description

Technical Field

[0001] This application relates to the field of semiconductor testing equipment technology, and more specifically, to a testing and sorting machine. Background Technology

[0002] Semiconductor turret test and sorting machines are one of the important automated equipment in the chip design and inspection stage and the final testing stage of finished products.

[0003] Semiconductor turret-type testing and sorting machines generally include a testing turntable and a material-carrying turntable. The testing turntable and the material-carrying turntable transfer materials through cross-movement. Specifically, the testing turntable has circumferentially distributed test seats and grippers, while the material-carrying turntable has circumferentially distributed suction nozzles. During operation, the suction nozzles place materials on the test seats or retrieve materials. The grippers are pushed laterally by cam plates fixed to one side of the testing turntable, automatically opening and closing to secure the material on the test seats. However, during the rotation of the testing turntable to a stop, the grippers may be in an open state before or after the turntable stops rotating. This can cause the material position to shift, resulting in the suction nozzles picking up material at an angle. The angled material may become stuck during positioning and alignment, defective sorting, and good product collection. Utility Model Content

[0042] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0043] refer to Figures 1 to 3This application provides a testing and sorting machine, including a material conveyor turntable 100 and a testing turntable 200. The material conveyor turntable 100 is provided with multiple suction nozzles 110, which are located on the bottom surface of the material conveyor turntable 100 and evenly distributed along its circumference. The testing turntable 200 is located below the material conveyor turntable 100 and is arranged intersecting with it. The testing turntable 200 is provided with multiple testing units 210, which are evenly distributed along its circumference. During use, the material conveyor turntable 100 can also rotate circumferentially to rotate the suction nozzles 110 to the intersection of the material conveyor turntable 100 and the testing turntable 200, thereby allowing the suction nozzles 110 to place the adsorbed material 300 onto the testing unit 210, or to retrieve the material 300 from the testing unit 210. Meanwhile, the test turntable 200 can also rotate circumferentially to drive the test base unit 210 to rotate to different detection positions for different types of detection.

[0044] In some embodiments, the suction nozzle 110 can adsorb the material 300 by vacuuming, or by applying electricity to create electromagnetic attraction. In this embodiment, the suction nozzle 110 adsorbs the material 300 by vacuuming.

[0045] In some embodiments, the suction nozzle 110 can move up and down relative to the material conveyor turntable 100. For example, the suction nozzle 110 may be provided with a guide rod that extends along the height direction and slides in cooperation with the material conveyor turntable 100, so that the suction nozzle 110 can move up and down relative to the material conveyor turntable 100. It should be understood that in specific implementations, there is a certain height difference between the suction nozzle 110 and the testing unit 210 to ensure that the material conveyor turntable 100 and the testing turntable 200 can operate smoothly. Therefore, the suction nozzle 110 is configured to move up and down relative to the material conveyor turntable 100 so that the suction nozzle 110 can move to an appropriate height before placing the material 300 on the testing unit 210 or retrieving the material 300 from the testing unit 210, so as to facilitate the placement or suction of the material 300.

[0046] refer to Figure 1In some embodiments, the conveyor turntable 100 may also be equipped with a drive unit 120, which drives the suction nozzle 110 to move up and down relative to the conveyor turntable 100. For example, the drive unit 120 includes a mounting frame 121, a pressing rod 122, and a cylinder 123. The mounting frame 121 is mounted on the conveyor turntable 100, the pressing rod 122 is located above the conveyor turntable 100, the pressing rod 122 extends along the height direction and slides in cooperation with the mounting frame 121, and the cylinder 123 is mounted on the mounting frame 121 and its telescopic rod is connected to the upper end of the pressing rod 122. During use, the cylinder 123 can drive its telescopic rod to extend and retract, thereby driving the pressing rod 122 to move up and down. When the pressing rod 122 moves downward, it can apply pressure to the suction nozzle 110, causing it to move downward relative to the conveyor turntable 100. When the pressing rod 122 moves upward, the pressure of the pressing rod 122 disappears, and the suction nozzle 110 can return to its original position. It should be understood that, in practice, the nozzle 110 can be reset by the elastic force of the spring component.

[0047] refer to Figures 1 to 3 In some embodiments, the test stand unit 210 may include a test stand 211, a fixed block 212, and a movable block 213. The test stand 211 is mounted on the upper surface of the test turntable 200, and the upper surface of the test stand 211 has a platform 211a for placing material 300. The fixed block 212 is disposed on the test stand 211 and located on one side of the platform 211a. The movable block 213 is located on the side of the platform 211a away from the fixed block 212, and the movable block 213 can move relative to the test stand 211 to approach or move away from the material 300 to cooperate with the fixed block 212 to clamp and release the material 300. This arrangement enables the test stand unit 210 to place and fix the material 300. In this embodiment, the direction of movement of the movable block 213 is consistent with the radial direction of the test turntable 200.

[0048] refer to Figure 3 In some embodiments, the testing unit 210 may further include a fixed base 214 and a mounting base 215. The movable block 213 is movably mounted on the turntable via the fixed base 214 and the mounting base 215, so that the movable block 213 can move relative to the testing base 211 to approach or move away from the material 300. Specifically, the fixed base 214 is mounted on the bottom surface of the testing turntable 200. The movable block 213 is mounted on the mounting base 215, and the mounting base 215 is mounted on the fixed base 214 and can move relative to the fixed base 214 in a direction approaching or moving away from the material 300. In this embodiment, the movable block 213 is indirectly mounted on the mounting base 215. For example, a support plate 216 is provided on the side of the mounting base 215, and a clamp 217 is mounted on the top surface of the support plate 216. The movable block 213 is mounted on the clamp 217.

[0049] In some embodiments, the mounting base 215 is configured to be pressed by an external object when the test turntable 200 rotates to a set position, thereby causing the movable block 213 to move away from the material 300. For example, as Figure 2 As shown, a cam plate 230 can be provided on one side of the test turntable 200, and the cam plate 230 is located on the moving trajectory of the mounting base 215. During the circumferential rotation of the test turntable 200, the mounting base 215 can slide over the cam plate 230, and the cam plate 230 can apply pressure to the mounting base 215 along the radial direction of the test turntable 200, so that the mounting base 215 drives the movable block 213 to move away from the material 300, so as to release the material 300 so that it can be retrieved by the suction nozzle 110.

[0050] refer to Figure 3 In some embodiments, the mounting base 215 is provided with a wheel 215a, which is used to receive pressure from external objects and rotates circumferentially when subjected to pressure. For example, the wheel 215a can be a bearing, which is located at the outer end of the mounting base 215 (i.e., the end of the mounting base 215 away from the center of the test turntable 200). When the mounting base 215 slides past the cam plate 230, the bearing and the cam plate 230 are in rotational engagement. This arrangement reduces the friction between the mounting base 215 and the cam plate 230, which helps to improve the service life of the parts.

[0051] refer to Figure 3 In some embodiments, the measuring unit 210 further includes an elastic element 218, which is disposed between the mounting base 215 and the fixed base 214. The elastic element 218 is configured to enable the mounting base 215 to move the movable block 213 closer to the material 300 when no external force is applied. Specifically, the elastic element 218 can be a spring, which is supported between the mounting base 215 and the fixed base 214. When the mounting base 215 receives an external force and moves the movable block 213 away from the material 300, the spring can contract to accumulate potential energy. When the external force disappears, the spring can move the mounting base 215 closer to the material 300 under its own elastic force, thereby enabling the mounting base 215 to move the movable block 213 closer to the material 300.

[0052] refer to Figure 3 and Figure 4In some embodiments, the movable block 213 is provided with an air passage 213a and an air inlet 213b and an air outlet 213c connected to the air passage 213a. The air outlet 213c faces the material 300, that is, the air outlet 213c is located on the side of the movable block 213 facing the material 300. The test sorting machine also includes a blowing unit 220, which faces the air inlet 213b of the air passage 213a. In actual use, the blowing unit 220 can blow air into the air passage 213a through the air inlet 213b, so that the airflow passes through the air passage 213a and blows towards the material 300 to adjust the position of the material 300. Specifically, during the process of the mounting base 215 moving the movable block 213 away from the material 300 to release the material 300, the material 300 may move from a fixed position, such as Figures 8 to 10 As shown, this affects the accuracy of the suction nozzle 110 in picking up the material 300. Therefore, after the movable block 213 releases the material 300, blowing air onto the material 300 through the side of the movable block 213 facing the material 300 can move the material 300 closer to the fixed block 212 to fit against the fixed block 212, as shown. Figure 11 As shown, this ensures the accuracy with which the suction nozzle 110 picks up the material 300.

[0053] refer to Figure 3 and Figure 4 In some embodiments, the air outlet 213c includes a first air outlet 213c-1 and a second air outlet 213c-2, which are arranged side by side along the length of the material 300. For example, the first air outlet 213c-1 and the second air outlet 213c-2 are arranged side by side in the horizontal direction, that is, the length of the material 300 is consistent with the horizontal direction. This arrangement can simultaneously form two airflows, which can cause the material 300 to be subjected to force at two points on its side at the same time, thereby enabling the material 300 to move smoothly when adjusting its posture. Of course, in other embodiments, the number of air outlets 213c can be greater.

[0054] refer to Figure 4 In some embodiments, the air passage 213a includes a first air passage 213a-1 and a second air passage 213a-2. The first air passage 213a-1 is connected to the air inlet 213b and the first air outlet 213c-1, respectively. The second air passage 213a-2 is connected to the air inlet 213b and the second air outlet 213c-2, respectively. The first air passage 213a-1 and the second air passage 213a-2 are V-shaped. This arrangement allows the two airflows to be deflected outwards, thereby increasing the distance between the two force points on the side of the material 300 and further improving the stability of the material 300 during movement.

[0055] In some embodiments, the air inlet 213b may be located on the side of the movable block 213, or the air inlet 213b may be located on the top surface of the movable block 213. In this embodiment, the air inlet 213b is located on the top surface of the movable block 213, such as... Figure 3 and Figure 4 As shown.

[0056] refer to Figure 1 , Figure 2 and Figure 5 In some embodiments, the blowing unit 220 includes a blowing assembly, which includes a mounting plate 221, an air supply passage 222, and an air nozzle 223. The mounting plate 221 is suspended above the test turntable 200. The air supply passage 222 is mounted on the mounting plate 221. The air nozzle 223 is connected to the air supply passage 222 and faces vertically downward toward the air inlet 213b. During use, the air supply passage 222 supplies air to the air nozzle 223 so that the air nozzle 223 blows air into the air passage 213a. In this embodiment, the air supply passage 222 is indirectly mounted on the mounting plate 221. For example, the blowing unit 220 also includes an L-shaped bracket 224, the horizontal portion of which is connected to the edge of the mounting plate 221 via a clamp 225, and the vertical portion of which is used to mount the air supply passage 222. Furthermore, both the horizontal and vertical portions of the L-shaped bracket 224 can be provided with waist-shaped holes to facilitate adjustment of the position of the L-shaped bracket 224 relative to the clamping plate 225 and the position of the air supply passage 222 relative to the L-shaped bracket 224.

[0057] refer to Figure 5 In some embodiments, the air blowing unit 220 further includes a throttle valve 226, which is connected in series with the air inlet 213b of the air inlet channel. During use, the throttle valve 226 can adjust the airflow to prevent the material 300 from being blown away and thrown due to excessive airflow.

[0058] refer to Figure 7 In some embodiments, the air-blowing unit 220 further includes a solenoid valve 227, which is connected in series in the air supply passage 222. The solenoid valve 227 is used to control the opening and closing of the air supply passage 222 so that the nozzle 223 blows air into the air passage 213a. In actual use, when the solenoid valve 227 receives a control signal for the first time, it can control the air supply passage 222 to open, so that the nozzle 223 blows air into the air passage 213a. When the solenoid valve 227 receives a control signal for the second time, it can control the air supply passage 222 to close, so that the nozzle 223 stops blowing air into the air passage 213a.

[0059] refer to Figure 6 and Figure 7In some embodiments, the air blowing unit 220 further includes a control component 228, which includes a sensor 228a, a movable platform 228b, and a sensor 228c. The sensor 228a is disposed on the fixed plate 221. The movable platform 228b is disposed on the fixed plate 221 and is movable relative to the fixed plate 221. The sensor 228c is disposed on the movable platform 228b and electrically connected to the solenoid valve 227. The sensor 228c can be triggered by the sensor 228a when the movable platform 228b moves relative to the fixed plate 221, thereby causing the solenoid valve 227 to control the opening and closing of the air supply path 222. This configuration allows the solenoid valve 227 to be controlled by triggering, thus controlling the opening and closing of the air supply path 222. In this embodiment, the movable platform 228b is a lifting platform, capable of reciprocating up and down relative to the fixed plate 221. Correspondingly, sensor 228c can be triggered by sensor 228a during the lifting and lowering of the movable platform 228b, thereby causing solenoid valve 227 to control the opening and closing of the air supply path 222. For example, sensor 228c can be triggered by sensor 228a when the movable platform 228b moves upward, causing solenoid valve 227 to control the air supply path 222 to open; sensor 228c can also be triggered by sensor 228a when the movable platform 228b moves downward, causing solenoid valve 227 to control the air supply path 222 to close. It should be understood that, in specific implementations, in order to ensure that sensor 228c can be triggered by sensor 228a during the up-and-down movement, sensor 228a should be located between the highest and lowest points of the movable platform 228b, such as by mounting sensor 228a to fixed plate 221 via support rod 228d.

[0060] The working principle of the test sorting machine in this application embodiment is as follows: When the equipment is running, the test turntable 200 rotates to a certain angle and then stops, so that a test seat unit 210 is located at the intersection of the turntables. At this time, the material-carrying turntable 100 can use the suction nozzle 110 to pick up the material 300 on the support 211a of the test seat unit 210 and retrieve it. Then, the next material 300 picked up on the suction nozzle 110 can be placed on the support 211a on the test seat 211. After the test turntable 200 stops rotating, the mounting base 215 of the test base unit 210 can drive the movable block 213 to move away from the material 300 under the action of the cam plate 230, so as to release the material 300. At the same time, the movable platform 228b can drive the sensor 228c to move upward. When the movable platform 228b rises to the set height, the sensor 228a triggers the sensor 228c. The sensor 228c sends a high-level signal to make the solenoid valve 227 control the air supply path 222 to open, so that the airflow blows towards the material 300 through the air passage 213a, thereby adjusting the position of the material 300. As the test turntable 200 continues to rotate, the mounting base 215 of the testing unit 210 disengages from the cam plate 230. The mounting base 215 drives the movable block 213 to move closer to the fixed block 212, so as to cooperate with the fixed block 212 to clamp the material 300. At the same time, the movable platform 228b can drive the sensor 228c to move downward. When the movable platform 228b descends to a certain height, the sensor 228a triggers the sensor 228c again. The sensor 228c sends a high-level signal to cause the solenoid valve 227 to control the air supply circuit 222 to cut off the air supply. Thus, the material-carrying turntable 100 and the test turntable 200 complete one cycle of material loading and unloading, and so on.

[0061] The testing and sorting machine of this application embodiment has a testing unit 210 that can be used to place and fix the material 300. Furthermore, the testing unit 210 can push the material 300 by pneumatic means so that the material 300 can be adjusted in position when it is released. This can improve the problem of the suction nozzle 110 of the existing testing and sorting machine picking up the material 300 at an angle, thereby avoiding the material 300 from getting stuck when it passes through positioning and guidance, defective classification, and good product collection.
