[0039] The following combines the drawings and embodiments to further describe in detail the specific embodiments of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.
[0040] Such as Figures 1 to 2The swing arm device applicable to a wafer cleaning device includes a device base 1. What makes it different is that several vertical guide plates 2 are arranged on the device base 1. An accommodation space is formed between the vertical guide plates 2, and a spacer 3 is arranged at the upper ends of the vertical guide plates 2. In this way, effective internal storage of subsequent various devices and components can be achieved, centralized layout can be realized, and subsequent waterproof planning can be facilitated. At the same time, one of the vertical guide plates 2 is set as a driving and bearing plate, and a Z-direction driving device 4 is arranged inside the accommodation space of this driving and bearing plate. Another adjacent vertical guide plate 2 is set as a displacement guiding plate, and a Z-direction guiding device 5 is arranged inside the accommodation space of this displacement guiding plate. Moreover, the Z-direction driving device 4 is provided with a mounting plate 6, and the mounting plate 6 is connected to the Z-direction guiding device 5 to realize the free up and down movement of the subsequent mounting plate 6, which can meet the adjustment of the horizontal position of the subsequent swing arm device 9. During implementation, a steering driving device 7 is installed on the Z-direction guiding device 5 of the present invention. The steering driving device 7 is conductively connected to a vertical adjustment component 8. The upper end of the vertical adjustment component 8 passes through the spacer 3, and the lower end of the vertical adjustment component 8 is movably connected to the mounting plate 6. In this way, the vertical adjustment component 8 can be controlled to achieve circumferential rotation. In order to cooperate with the position distribution of the brush head or the coverage of the spraying area during cleaning, a swing arm device 9 is arranged on the vertical adjustment component 8 of the present invention. Specifically, a reserved space is arranged inside the swing arm device 9, and a mounting hole communicating with the reserved space is arranged at the front end of the swing arm device 9. In this way, various brush head matching components for cleaning or spraying components can be selected and installed according to actual needs.
[0041] Combined with a preferred embodiment of the present invention, the Z-direction driving device 4 is a Z-direction linear motor, and the driving end of the Z-direction linear motor is provided with a mounting plate 6. At the same time, the mounting plate 6 is movably connected to the Z-direction guiding device 5, and a steering driving device 7 is arranged on the mounting plate 6. In this way, effective "driving bridging" can be achieved through the mounting plate 6, the accommodation space can be effectively utilized, and the control of the Z-direction driving can be realized. Moreover, through the participation of the Z-direction guiding device 5, stable Z-direction displacement can be achieved.
[0042] During implementation, the Z-direction guiding device 5 adopted by the present utility model includes a guide rail 10 connected to the vertical guiding plate 2. A slider 11 is movably arranged on the guide rail 10, and a contact plate 12 is arranged on the slider 11. The contact plate 12 is connected to the mounting plate 6 of the Z-direction driving device 4. In this way, the mounting plate 6 is driven to displace smoothly. Specifically, the guide rail 10 is an I-shaped slide rail distributed in parallel, and both sides of the slider 11 are embedded into the corresponding I-shaped slide rails. In this way, appropriate limiting can be satisfied, ensuring smooth up and down operation without abnormal separation. At the same time, the present utility model also arranges a lower-end guiding plate 13 on the contact plate 12. A guiding hole is opened on the lower-end guiding plate 13, and one end of the vertical adjustment component 8 passes through the guiding hole. In this way, better bottom limiting can be achieved, and abnormal skewing will not occur due to unbalanced load when the vertical adjustment component 8 rotates.
[0043] Furthermore, the steering driving device 7 adopted is a servo motor. A main transmission wheel 14 is arranged on the driving end of the servo motor. The vertical adjustment component 8 includes a secondary transmission wheel 15 movably connected to the mounting plate 6. A belt 16 is sleeved between the main transmission wheel 14 and the secondary transmission wheel 15. In this way, stable transmission can be achieved through the belt 16. Compared with direct drive of the servo motor, the speed ratio control can be achieved through the sizes of each transmission wheel. And a vertical guide rod 17 is arranged on the secondary transmission wheel 15. The vertical guide rod 17 is connected to the swing arm device 9. In order to enable the vertical guide rod 17 to concurrently realize "supply wire routing" inside, the adopted vertical guide rod 17 is of a hollow structure, and a wire routing / liquid supply space is formed inside. Thus, wires or water pipes can be arranged in the vertical guide rod 17. At the same time, a guide through hole 21 is arranged on one side of the vertical guide rod 17, and a connection valve head 18 is arranged on the guide through hole 21. In this way, external pipelines can be introduced through the connection valve head 18, and positioning at the interface can be realized, avoiding excessive pulling displacement of the pipelines caused by the rotation of the vertical guide rod 17.
[0044] Combined with actual implementation, if surface contact type cleaning assistance needs to be realized, a driving component can be arranged in the reserved space, a cleaning brush is arranged on the mounting hole, and the driving component is connected to the cleaning brush. The driving component is a servo motor. In this way, with the operation of the driving component, the cleaning brush can be driven to rotate to perform appropriate contact cleaning on the surface of the wafer.
[0045] If cleaning liquid or water needs to be assisted for spraying. Then the present utility model can arrange a water pipe in the reserved space. At the same time, a spray head is arranged on the mounting hole, and the spray head is connected to the water pipe. In this way, through the connected spraying device and using the actually rotatable range of the swing arm device 9, coverage spraying within a certain area can be realized to spray the cleaning liquid or water on the surface of the wafer. Of course, other components can also be arranged and selected according to needs, which will not be elaborated here.
[0046] Furthermore, in order to meet the subsequent layout of the introduction of various wires such as electric wires and water pipes, a clearance hole 20 is provided on the vertical guide plate 2. During implementation, the clearance hole 20 can be adapted to the waterproof ring 19 or a plug cover. Figure 2 As shown, for some pipelines that need to be laid out independently, a number of joint pipelines 22 are independently arranged on the corresponding vertical guide plates 2.
[0047] At the same time, in order to improve the waterproof effect of the upper partition plate 3, a through hole is provided on the partition plate 3, and a waterproof ring 19 is provided on the through hole, and the vertical guide rod 17 at the upper end of the vertical adjustment component 8 passes through the waterproof ring 19. In this way, the infiltration of external water stains can be avoided to the greatest extent.
[0048] The working principle of the utility model is as follows:
[0049] The Z-direction guide device 5 and the Z-direction drive device 4 cooperate with each other to drive the swing arm device 9 to reach a suitable horizontal height, thereby ensuring that the subsequent range of movement of the swing arm device 9 can cover the current wafer surface.
[0050] Take contact cleaning as an example.
[0051] The actual height of the vertical adjustment assembly 8 is adjusted by using the Z-axis driving device 4, so that the swing arm device 9 drives the cleaning brush to contact the wafer.
[0052] Afterwards, the steering drive device 7 controls the vertical guide rod 17 to rotate, so that the swing arm device 9 drives the cleaning brush to have different cleaning contact ranges.
[0053] Take the spraying as an example.
[0054] The Z-direction guide device 5 and the Z-direction drive device 4 cooperate with each other to drive the swing arm device 9 to a suitable horizontal height. After that, the steering drive device 7 controls the vertical guide rod 17 to rotate, so that the swing arm device 9 rotates to a certain extent. At the same time, the spray head on the swing arm device 9 sprays under the operation of the connected spray equipment to clean the surface of the wafer.
[0055] It can be seen from the above text description and the accompanying drawings that the following advantages are achieved after adopting the utility model:
[0056] 1. Through the cooperation of the Z-axis drive device and the Z-axis guide device, the swing arm device can be driven to achieve stable up and down displacement to meet different working heights with high adaptability.
[0057] 2. Through the steering drive equipment, the swing arm device is controlled to have a larger coverage angle, which can increase the operating range and meet the needs of different wafer models.

[0059] 4. According to needs, the swing arm device can be made to carry the cleaning brush or the spray head, meeting the needs of different cleaning processes and having good versatility.
[0060] 5. For the layout of the cleaning device, two of the present utility models can be adopted to form a double swing arm coverage, having a better working range. Through the height dislocation of the swing arm device, there will be no movement interference.
[0061] In addition, the indicated orientation or positional relationship described in the present utility model is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or structure referred to must have a specific orientation, or be operated in a specific orientation structure.
