[0021] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0022] like Figures 1 to 3 As shown, a preferred embodiment of the present invention provides a wafer handling device, which includes a handling component. The handling component includes a mounting base 1. The mounting base 1 is provided with a rotating device 2, a telescopic device 3, and an adsorption device 4. The telescopic device 3 is disposed at the output end of the rotating device 2, and the adsorption device 4 is disposed at the output end of the telescopic device 3. The rotating device 2 is used to adjust the telescopic direction of the telescopic device 3, and the telescopic device 3 is used to drive and adjust the position of the adsorption device 4.
[0023] Specifically, in conventional technical solutions, robotic arms used for wafer handling and transfer often have very complex structures and require a large amount of space. Due to their complex structure, wafer transfer efficiency is very low, and the transfer process can easily damage the wafer. In this embodiment, however, the rotating device 2 can adjust the extension and retraction direction of the telescopic device 3, allowing the telescopic device 3 to drive the adsorption device 4 at its end to extend and retract in different directions to handle wafers in different orientations. Once the adsorption device 4 has stably adsorbed the wafer, the telescopic device 3 can drive the adsorption device 4 and the wafer to retract to their original positions. Subsequently, the rotating device 2 drives the telescopic device 3, the adsorption device 4, and the wafer to rotate, thus realizing the wafer handling and transfer. The entire wafer handling and transfer process is smoother, more flexible, and more efficient. Furthermore, because the adsorption device 4 can move in any direction and adsorb the wafer, the handling device can meet different handling needs within a smaller space, enabling the handling and transfer of more and more different wafers more flexibly, and improving the space utilization and handling flexibility of the wafer handling device.
[0024] In some embodiments, the rotating device 2 includes a first geared motor 21, which is disposed on one side of the mounting base 1. The output end of the first geared motor 21 passes through the bottom wall of the mounting base 1 and is connected to a rotating platform 22. A telescopic device 3 is fixedly connected to the top surface of the rotating platform 22.
[0025] Specifically, the first geared motor 21, located on the outer side of the bottom wall of the mounting base 1, drives the rotating platform 22 located inside the mounting base 1 to rotate, thereby driving the telescopic device 3 and the adsorption device 4 on it to rotate. The first geared motor 21 is fixedly connected to the mounting base 1. The geared motor can reduce the rotation speed of the rotating platform 22 and precisely control the rotation angle of the rotating platform 22, so that the telescopic device 3 can accurately and stably face different directions. The telescopic device 3 can then more accurately drive the adsorption device 4 to move in different directions to adsorb the wafer. The accuracy of wafer adsorption and transportation is higher, and it is less likely to damage the wafer, reducing the risk of wafer transportation and transfer.
[0026] In some embodiments, the telescopic device 3 includes a first telescopic module 31 and a second telescopic module 32 arranged in parallel, the first telescopic module 31 and the second telescopic module 32 are slidably connected, and the adsorption device 4 is slidably connected to the second telescopic module 32.
[0027] Furthermore, the first telescopic module 31 is driven to be connected to the first slider 33, the second telescopic module 32 is fixedly connected to the fixing block 34, and the first slider 33 is fixedly connected to the fixing block 34; the second telescopic module 32 is slidably connected to the side away from the fixing block 34, and the second slider 35 is fixedly connected to the adsorption device 4.
[0028] Specifically, in this embodiment, the telescopic device 3 includes two telescopic modules, which can achieve double-range telescopic extension, increasing the range of movement of the adsorption device 4. The telescopic device 3 can drive the adsorption device 4 to move a longer distance, thereby adsorbing wafers at a greater distance. This allows the entire handling device to adjust the distance the adsorption device 4 moves according to the storage location of different wafers. As needed, the adsorption device 4 can adsorb and transport wafers over a larger range, thus meeting more diverse handling requirements.
[0029] In some embodiments, the adsorption device 4 includes a non-contact suction cup or a soft-contact suction cup. Specifically, the adsorption device 4 may employ a ceramic finger vacuum suction cup, thereby enabling more stable and reliable adsorption and transfer of the wafer.
[0030] In some embodiments, an adjustment component is also included. The adjustment component includes a mounting plate 5. The mounting plate 5 is provided with a lifting module 51 and a second reduction motor 52. The second reduction motor 52 is connected to the lifting module 51 in a transmission manner. The lifting module 51 is driven to be connected to a mounting bracket 53. The mounting bracket 53 is fixedly connected to a mounting base 1 and a first reduction motor 21.
[0031] Furthermore, the mounting bracket 53 includes a first plate 531 and a second plate 532 that are fixedly connected. The first plate 531 is driven to be connected to the lifting module 51, and the second plate 532 is fixedly connected to the mounting base 1 and the first reduction motor 21. A support plate 533 is provided between the first plate 531 and the second plate 532.
[0032] Specifically, in the actual wafer handling process, when the adsorption device 4 moves directly above the semi-circular wafer to be handled, it needs to be lowered to bring the repair device closer to the wafer for stable adsorption. Similarly, for wafers that need to be lowered, the adsorption device 4 needs to be lowered to a suitable height for safe placement, preventing the risk of wafer damage from falling. Therefore, it is necessary to set up an adjustment component to adjust the height of the mounting base 1 and the adsorption device 4 on it. The second reduction motor 52, in conjunction with the lifting module 51, can stably lower the height of the mounting base 1, reducing the adverse effects of vibration and ensuring stability, accuracy, and safety during wafer handling. Furthermore, the support plate 533 in the mounting bracket 53 further improves the structural stability and support strength, ensuring that the mounting base 1 does not vibrate or sway during lifting, further enhancing the stability of wafer handling.
[0033] In some embodiments, the mounting base 1 is equipped with a rotary cable chain 11, the mounting plate 5 is equipped with a lifting cable chain 54, and the rotating platform 22 is equipped with a telescopic cable chain 36. The cable chains enable the storage, traction, and protection of various pipes and lines. The rotary cable chain 11, in particular, is useful because the first reduction motor 21 drives the rotating platform 22 to rotate, facilitating the telescopic device 3 to drive the adsorption device 4 to extend and retract in different directions. The rotating platform 22 can rotate more than 360 degrees to adapt to a wider range of applications. Since the adsorption device 4 needs to be connected to a vacuum device via an air pipe, the air pipe and cable can easily become entangled during the rotation of the rotating platform 22, affecting the operation of the entire handling device. The rotary cable chain effectively stores and guides the air pipe and cable, ensuring the normal operation of the entire handling device.
[0034] In some embodiments, a plurality of wafer storage boxes are also included, which are arranged around the mounting base 1 and are used to store wafers. In one specific embodiment, the plurality of wafer storage boxes are evenly arranged along an arc, thereby facilitating the telescopic device 3 to drive the adsorption device 4 into different wafer storage boxes to transport and store wafers, resulting in higher wafer transport and transfer efficiency.
[0035] In summary, this utility model provides a wafer handling device that can adjust the orientation of the telescopic device 3 and the adsorption device 4 through the rotating device 2, thereby facilitating the telescopic device 3 to drive the adsorption device 4 to extend and retract in different directions, and thus adsorbing and storing wafers in different positions, greatly improving the wafer handling efficiency. At the same time, the entire handling device is more flexible and versatile, and can handle wafers located in different directions in a smaller space.
[0036] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this utility model, and these improvements and substitutions should also be considered within the protection scope of this utility model.
