Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0049] This application discloses an optical mirror sample adjustment gripper and a semiconductor collaborative robot.

[0050] Please see Figure 1 One embodiment of the optical mirror sample adjustment gripper provided in this application includes:

[0051] The carrier 1, the operating component 2, the transmission component 4, and the driving component 3; one end of the carrier 1 has an extension 11; the carrier 1 can be a plate structure, with an extension plate integrally extending from one end to form the extension 11.

[0052] The operating component 2 is rotatably mounted on the end of the extension 11 away from the carrier 1; the driving component 3 is mounted on the carrier 1 and connected to the operating component 2 through the transmission assembly 4, and is used to drive the operating component 2 to rotate.

[0053] The optical microscope sample adjustment gripper designed in this application has the following beneficial effects:

[0054] 1. The extension part 11 is designed to extend the length of the carrier 1 so that it can flexibly extend into the underside of the lens of the optical stage. The end of the extension part 11 is rotatably mounted with the operating component 2. The driving component 3 drives the operating component 2 to rotate through the transmission component 4, so that it does not need to be mounted on the extension part 11, thus avoiding excessively increasing the thickness of the extension part 11 and affecting the flexibility of operation under the lens.

[0055] 2. The design of the operating component 2, along with the cooperation of the driving component 3 and the transmission component 4, enables rotation control. This allows the angle of the turntable below the lens, used for placing wafers, to be electrically adjusted via the operating component 2. Compared to manual adjustment, this improves adjustment efficiency and accuracy, thereby enhancing detection efficiency and reliability, and meeting the semiconductor manufacturing industry's demand for efficient and high-precision production.

[0056] The above is Embodiment 1 of the optical microscope sample adjustment gripper provided in this application. The following is Embodiment 2 of the optical microscope sample adjustment gripper provided in this application. Please refer to the following for details. Figures 1 to 2 .

[0057] Based on the solution of Embodiment 1 above:

[0058] Furthermore, a rotating connector (not shown in the figure) is rotatably mounted on the extension 11, and the operating member 2 is detachably connected to the rotating connector.

[0059] By making the operating component 2 and the rotating connector detachable, the operating component 2 can be easily replaced according to different usage requirements. When adjusting different objects, the appropriate operating component 2 can be quickly replaced, enhancing versatility and applicability.

[0060] This detachable connection design also facilitates individual maintenance and repair of the operating component 2. Operating component 2 can be periodically disassembled for cleaning and other maintenance, ensuring smooth and precise rotation. Simultaneously, it makes inspection and repair of operating component 2 easier during maintenance, improving the equipment's lifespan and stability.

[0061] Furthermore, a bearing (not shown in the figure) is installed on the extension 11; a rotating connector is fixed to the bearing, and one end extends out of one side of the extension 11 for connecting the transmission assembly 4; the other end of the rotating connector extends out of the other side of the extension 11 for connecting the operating member 2.

[0062] This method of mounting the rotating connector using bearings makes the rotation of the connector smoother and more stable. The bearings effectively reduce friction during rotation, lower energy loss, and ensure that the power of the drive component 3 is efficiently transmitted to the operating component 2. At the same time, the bearings also support and position the rotating connector, ensuring that it does not shift or wobble during rotation, thereby improving the rotational accuracy of the operating component 2.

[0063] Furthermore, regarding the detachable connection between the rotating connector and the operating component 2, it can be one of the following methods:

[0064] The other end of the rotating connector is provided with a first spline portion (such as a spline hole); the operating component 2 is provided with a second spline portion (such as a spline shaft) that is coaxially connected to the first spline portion and magnetically attracted to it.

[0065] This design, where the first and second splined sections are coaxially connected and magnetically attracted to each other, makes the connection between the operating component 2 and the rotating connector more stable. The splined connection can accurately transmit torque, ensuring that the operating component 2 will not slip during rotation, thus enabling precise adjustment of the optical mirror sample. At the same time, the magnetic attraction facilitates the disassembly and installation of the operating component 2. When replacing the operating component 2, it can be easily removed by overcoming the magnetic force, and after replacement, it can be quickly and stably reconnected, greatly improving the efficiency of replacing the operating component 2.

[0066] In addition, for the detachable connection between the rotating connector and the operating component 2, the following second method can also be used:

[0067] The other end of the rotating connector is provided with a first insertion part (such as a cylindrical structure with an insertion cavity for the second insertion part to be inserted into); the first insertion part is provided with a first pin hole; the operating member 2 is provided with a second insertion part (such as a rod inserted into the first insertion part) that is inserted and engaged with the first insertion part; the second insertion part is provided with a second pin hole that is connected to the first pin hole; the first pin hole and the second pin hole are fastened together by a pin.

[0068] This plug-in connection method, secured with a pin, makes installation relatively simple and quick. Simply insert the second plug of the operating component 2 into the first plug of the rotating connector, aligning the first and second pin holes, and then insert the pin to complete the connection. For disassembly, simply pull out the pin to separate the operating component 2 from the rotating connector. Simultaneously, the pin effectively prevents the operating component 2 from detaching from the rotating connector during rotation, ensuring connection stability. The pin can be a quick-release pin; there are no specific limitations.

[0069] In practical applications, the two detachable connection methods mentioned above can be flexibly selected according to specific working scenarios and needs to better utilize the performance of the optical mirror sample adjustment gripper, meet different operational requirements, and further improve the efficiency and accuracy of optical mirror sample adjustment in semiconductor manufacturing processes. Of course, the design is not limited to the two detachable connection methods mentioned above; those skilled in the art can modify the design according to actual needs without restriction.

[0070] Furthermore, the operating component 2 includes at least one of the following: an internal hexagonal structure, an external hook structure, a cross-shaped structure, and a straight-line structure. Taking the internal hexagonal structure as an example, it can be used to adjust the height of the dial on the holder (the base for fixing the optical mirror); taking the external hook structure as an example, it can be used to adjust the angle of the dial on the holder.

[0071] Taking the internal hexagonal structure as an example, it can be fitted onto the hexagonal adjustment head used to adjust the height of the turntable. The height of the turntable is adjusted by rotating the adjustment head. Taking the external hook (L-shaped with a bent hook) as an example, its bent hook can be inserted into the adjustment knob with an adjustment hole used to adjust the angle of the turntable. When the bent hook is inserted into the adjustment hole, the rotation center of the operating part 2 coincides with the adjustment knob. By driving the external hook to rotate, the adjustment knob can be rotated to achieve adjustment.

[0072] Taking a cross-shaped structure as an example, such as a cross-shaped screwdriver head, and a flathead structure, such as a flathead screwdriver head, as an example, the structure can be used. Hexagonal, hook-shaped, and flathead structures can be respectively mounted on independent operating components 2, or two of them can be integrated onto the same operating component 2. Preferably, each operating component 2 is configured with one type of operating structure. Of course, in addition to the above-mentioned operating structures, other types of operating structures can also be included. The specific design can be varied according to the actual object being operated, and there are no restrictions.

[0073] Furthermore, the transmission assembly 4 includes a transmission belt 42, a drive pulley 41, and a driven pulley 43; the drive pulley 41 is fixedly connected to the output shaft of the drive member 3; the driven pulley 43 is fixedly connected to the operating member 2; the transmission belt 42 is connected to the drive pulley 41 and the driven pulley 43 to make the drive pulley 41 and the driven pulley 43 rotate synchronously.

[0074] This combination of transmission belt 42, drive pulley 41, and driven pulley 43 features a simple structure and smooth transmission. The transmission belt 42 effectively transmits the power of the driving component 3 from the drive pulley 41 to the driven pulley 43, enabling the rotation of the operating component 2. The driven pulley 43 can be fixed to a rotating connecting member, while the output shaft of the driving component 3 can be oriented downwards and fixed to the carrier 1 by a fixed bracket. The drive pulley 41 is then fixed to the output shaft.

[0075] Furthermore, the transmission belt 42 is a synchronous belt. The synchronous belt has a precise transmission ratio, ensuring the synchronous rotation of the driving pulley 41 and the driven pulley 43, preventing slippage, and thus ensuring the accuracy and stability of the rotation of the operating component 2. The synchronous belt operates with low noise, running quietly and without significantly interfering with the working environment. Moreover, the maintenance of the synchronous belt is relatively simple; it only requires periodic checks of its tension and wear, and adjustment or replacement as necessary.

[0076] Furthermore, the driving component 3 is a servo motor capable of forward and reverse rotation. Servo motors offer advantages such as high control precision and fast response speed. The ability to rotate in both directions allows the operating component 2 to turn clockwise or counterclockwise according to actual needs, enabling flexible adjustment of the optical mirror sample at multiple angles and heights. In semiconductor manufacturing, the adjustment of the optical mirror sample often requires precise angle control. The servo motor can accurately drive the operating component 2 to rotate to the designated position through precise control signals, meeting the high-precision requirements of the production process.

[0077] Furthermore, the optical mirror sample adjustment gripper also includes a protective cover 5. The protective cover 5 is installed on the carrier 1 and the extension 11 to cover the transmission assembly 4 and the drive component 3. The protective cover 5 prevents dust, debris, etc., from entering the transmission assembly 4 and the drive component 3, avoiding damage and affecting the normal operation of the equipment. At the same time, the protective cover 5 also provides a certain degree of protection, preventing operators from accidentally contacting the transmission assembly 4 and the drive component 3 during operation, thus avoiding safety accidents.

[0078] Furthermore, the optical mirror sample adjustment gripper also includes a quick-change tray 6. The quick-change tray 6 is mounted on the carrier 1. The design of the quick-change tray 6 allows the optical mirror sample adjustment gripper to be quickly replaced and connected to other equipment or tools. In the semiconductor manufacturing process, it may be necessary to quickly change different types of adjustment grippers or other tools according to different process requirements or production tasks. The quick-change tray 6 can greatly improve changeover efficiency, reduce equipment downtime, and increase production efficiency.

[0079] This application also discloses a semiconductor collaborative robot, including a multi-axis robotic arm and a lens sample adjustment gripper; the end of the multi-axis robotic arm is connected to the lens sample adjustment gripper.

[0080] Furthermore, it also includes a worktable; a multi-axis robotic arm is mounted on the worktable; a gripper bracket is mounted on the worktable; the gripper bracket has multiple placement stations for placing optical mirror sample adjustment grippers; there are multiple optical mirror sample adjustment grippers, and each can be detachably connected to the end of the multi-axis robotic arm.

[0081] This semiconductor collaborative robot design significantly enhances the automation and flexibility of the semiconductor manufacturing process. Multi-axis robotic arms (such as 3-axis or 6-axis arms) can move freely in three-dimensional space, reaching various positions on the optical microscope stage to perform adjustments on the optical microscope samples at different locations. Multiple optical microscope sample adjustment grippers can be quickly replaced according to actual needs, further improving work efficiency.

[0082] The multiple placement stations on the gripper support provide a safe and orderly storage location for the optical microscope sample adjustment grippers. When a gripper is not in use, it can be placed in the corresponding station, avoiding damage or loss caused by random placement. At the same time, the multi-axis robotic arm can easily grasp the required gripper from the placement station, enabling rapid switching between different grippers.

[0083] In actual semiconductor manufacturing production lines, this type of semiconductor collaborative robot can automatically complete the adjustment of optical mirror samples according to a preset program. The multi-axis robotic arm moves to the vicinity of the optical mirror stage according to a predetermined trajectory, selects a suitable optical mirror sample from the gripper support as needed, adjusts the gripper, and then drives the operating component 2 to rotate via the drive component 3 to precisely adjust the height or angle of the turntable.

[0084] The above provides a detailed description of the optical mirror sample adjustment gripper and semiconductor collaborative robot provided in this application. For those skilled in the art, based on the ideas of the embodiments of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
