DETAILED DESCRIPTION
[0029] The following is combined with Figure 1-5 This application is described in further detail.
[0030] Embodiment 1:
[0031] The present application embodiment discloses a transport guide device for a magnetron sputtering coating machine, referring to Figure 1, including a mounting frame 1, a carrier plate 11 is mounted on the mounting frame 1, a transport device 2 for transporting the carrier plate 11 is mounted on the mounting frame 1, and a guiding device 3 for assisting the transport process of the carrier plate 11 is connected to the transport device 2.
[0032] The silicon wafers are arranged on the carrier 11, and the carrier 11 is transported by the transport device 2 to achieve rapid transportation of the carrier 11 in the magnetron sputtering coating machine. The transport device 2 is assisted by the guide device 3 to transport the carrier 11 to increase the stability during the transportation of the carrier 11, and the static electricity on the carrier 11 is removed at the same time, which is beneficial to improving the efficiency of the magnetron sputtering coating machine during use.
[0033] Reference Figure 1 and Figure 2 The transport device 2 includes a mounting cylinder 21, which is fixedly mounted on the mounting frame 1. Mounting cylinders 21 are arranged on both sides of the mounting frame 1 in the transport direction, and eight mounting cylinders 21 are fixedly mounted on each side. A rotating shaft 22 is rotatably mounted on the mounting cylinder 21, and a synchronous wheel 23 is fixedly connected to one end of the rotating shaft 22 located on the outer side of the mounting frame 1. In this embodiment, a motor and a synchronous belt for controlling the rotation of the rotating shaft 22 are arranged in the magnetron sputtering coating machine. The synchronous belt connects all the synchronous wheels 23 on the same side. The connection relationship between the synchronous wheel and the synchronous belt is a prior art and is not shown in the figure.
[0034] Reference Figure 2 and Figure 3 One end of the rotating shaft 22 away from the synchronous wheel 23 is fixedly connected to a rotating drum 24 , and four mounting grooves 241 are equidistantly provided on the rotating drum 24 . Four anti-slip rings 25 are installed on the rotating drum 24 , and the four anti-slip rings 25 are respectively embedded in the four mounting grooves 241 .
[0035] The carrier 11 is placed on the rotating drum 24, and the friction between the carrier 11 and the rotating drum 24 is increased by the anti-slip ring 25 to prevent the carrier 11 from sliding during the transportation of the carrier 11. The synchronous belt is controlled by the motor to rotate, and the synchronous belt drives the synchronous wheel 23 on the same side to rotate at the same time. The synchronous wheel 23 drives the rotating shaft 22 to rotate, thereby rotating the rotating drum 24 to realize the rapid transportation of the carrier 11.
[0036] Reference Figure 3 and Figure 4The guiding device 3 includes a first guiding assembly 31, which is arranged on the mounting cylinder 21. The mounting cylinder 21 is the mounting cylinder 21 that the carrier 11 passes through for the first time in the transportation direction. The first guiding assembly 31 of the transportation device 2 includes a first connecting plate 311, which is fixedly mounted on the mounting cylinder 21. A first connecting shaft 312 is fixedly mounted on the first connecting plate 311. The first connecting shaft 312 is horizontally arranged. A rotating plate 313 is rotatably mounted on the first connecting shaft 312. A second connecting plate 314 is fixedly mounted on the first connecting plate 311. The second connecting plate 314 is located below the rotating plate 313. A first spring 315 is fixedly mounted on the second connecting plate 314. The first spring 315 is fixedly connected to the rotating plate 313 at one end away from the second connecting plate 314, and the first spring 315 is arranged away from the first connecting shaft 312. A second connecting shaft 316 is fixedly installed on the side wall of the rotating plate 313 close to the carrier plate 11. The second connecting shaft 316 is horizontally arranged. A first roller 317 is rotatably installed on the second connecting shaft 316. The width of the first roller 317 is smaller than the width of the rotating drum 24. In this embodiment, the first roller 317, the second connecting shaft 316, the first connecting shaft 312 and the first connecting plate 311 are all made of conductive materials, and a grounding wire is connected to the first connecting plate 311.
[0037] When the carrier 11 is not placed on the first roller 317, the horizontal height of the first roller 317 is higher than the height of the rotating drum 24. When the carrier 11 is placed on the rotating drum 24, the carrier 11 will preferentially contact the first roller 317, and the carrier 11 presses down the first roller 317. The rotating plate 313 is under pressure and will rotate downward around the first connecting shaft 312. At this time, the first spring 315 is subjected to force to generate elastic force on the rotating plate 313. The first spring 315 will push the rotating plate 313 to make the rotating plate 313 tend to rotate upward around the first connecting shaft 312, so that the first roller 317 and the carrier 11 always maintain abutment state. When the carrier 11 moves, the first roller 317 rotates on the second connecting shaft 316 to reduce the friction between the first roller 317 and the carrier 11, thereby facilitating the transportation of the carrier 11. While guiding the transport carrier 11, if there is static electricity on the carrier 11, the static electricity charge is transferred to the first roller 317, the second connecting shaft 316, the first connecting shaft 312 and the first connecting plate 311 in sequence, and finally the static electricity is eliminated by the grounding wire connected to the first connecting plate 311 to prevent the static electricity from affecting the coating process, which is beneficial to improving the efficiency of the magnetron sputtering coating machine for coating silicon wafers.
[0038] The guiding device 3 also includes a second guiding assembly 32, and the second guiding assembly 32 is installed on all the mounting tubes 21 except the mounting tube 21 equipped with the first guiding assembly 31. The second guiding assembly 32 includes a third connecting plate 321, and the third connecting plate 321 is fixedly installed on the mounting tube 21. A fourth connecting plate 322 is fixedly installed on the third connecting plate 321, and a third connecting shaft 323 is fixedly installed on the fourth connecting plate 322. The third connecting shaft 323 is vertically arranged, and a second roller 324 is rotatably installed on the third connecting shaft 323, and the second roller 324 abuts against the side wall of the carrier plate 11.
[0039] When the carrier 11 moves to abut against the second roller 324, the carrier 11 moves along the transport direction while driving the second roller 324 to rotate. The second rollers 324 of the second guide assemblies 32 on both sides of the carrier 11 abut against the carrier 11 to prevent the carrier 11 from shifting to both sides during movement, and guide the carrier 11 to keep the carrier 11 moving in a straight line, which is convenient for complete coating of the silicon wafers on the carrier 11, and is beneficial to improving the efficiency of the magnetron sputtering coating machine.
[0040] Embodiment 2:
[0041] Reference Figure 5 The difference between the embodiment of the present application and the embodiment 1 is that the second guide assembly 32 is equipped with an adjustment assembly 33 for adjusting the position of the second roller 324, and the third connecting plate 321 is provided with a first slide groove 3211. The adjustment assembly 33 includes a first screw rod 331, and the first screw rod 331 is threadedly connected to the third connecting plate 321. One end of the first screw rod 331 extends into the first slide groove 3211. The first screw rod 331 is located at the outer end of the first slide groove 3211 and is fixedly installed with a handle 3311. The first screw rod 331 extends into the first slide groove 3211 and one end is rotatably connected to the first slide plate 332. The first slide plate 332 is slidably connected to the third connecting plate 321.
[0042] The third connecting plate 321 is provided with a second slide groove 3212, and the second slide groove 3212 is located between the first slide groove 3211 and the second roller 324. The third connecting plate 321 is fixedly installed with a slide rod 334, and the slide rod 334 is arranged in the second slide groove 3212. The second slide plate 335 is slidably connected to the slide rod 334. The first slide plate 332 is fixedly installed with a push rod 333, and the push rod 333 passes through the third connecting plate 321 and extends into the second slide groove 3212. The push rod 333 is slidably connected to the third connecting plate 321, and the end of the push rod 333 away from the first slide plate 332 is fixedly connected to the second slide plate 335. A slider 336 is slidably mounted on the slide bar 334. The slider 336 is arranged on the side of the second slide plate 335 close to the second roller 324. A second spring 337 is sleeved on the slide bar 334. One end of the second spring 337 is fixedly connected to the second slide plate 335. The other end of the second spring 337 is fixedly connected to the slider 336. The slider 336 is fixedly connected to the fourth connecting plate 322.
[0043] When the carrier 11 is transported through the second guide assembly 32, the side wall of the carrier 11 contacts the second roller 324 first, and the carrier 11 pushes the second roller 324 to squeeze the second spring 337. The second spring 337 generates an elastic force to push the second roller 324 to contact the side wall of the carrier 11. When the carrier 11 is transported, the second rollers 324 on both sides of the carrier 11 push the carrier 11 toward the middle at the same time, and the second spring 337 changes the contact mode between the second roller 324 and the carrier 11 from rigid contact to elastic contact with an adjustable range, so that the transportation of the carrier 11 is smoother, and the second spring 337 can keep the second roller 324 and the carrier 11 in contact at all times and guide the carrier 11.
[0044] When it is necessary to adjust the pressing force between the second roller 324 and the carrier plate 11 or to maintain the second spring 337, the handle 3311 is turned to control the rotation of the first screw rod 331, the first screw rod 331 moves on the third connecting plate 321 and drives the first slide plate 332 to slide, the first slide plate 332 drives the push rod 333 to drive the second slide plate 335 to slide on the slide rod 334, and the elastic deformation degree of the second spring 337 is adjusted by changing the distance between the second slide plate 335 and the slider 336, so as to change the elastic force of the second spring 337, thereby changing the pressing degree between the carrier plate 11 and the second roller 324, so as to facilitate the rapid transportation of the carrier plate 11.
[0045] The implementation principle of the embodiment of the present application is: silicon wafers are placed on the carrier 11, the rotating drum 24 is controlled by a motor to drive the carrier 11 to move, and the guiding device 3 assists the transport device 2 in transporting the carrier 11 to increase the stability of the carrier 11 during transportation. The first guiding component 31 in the guiding device 3 guides the carrier 11 while removing the static electricity on the carrier 11, thereby reducing the impact of static electricity on the coating, which is beneficial to improving the efficiency of the magnetron sputtering coating machine during use.
