DETAILED DESCRIPTION

[0021] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0022] Reference Figures 1-4 , a device for cleaning electronic-grade hydrofluoric acid packaging containers, comprising a base 1, a horizontal rotation mechanism and a vertical rotation mechanism, wherein both ends of the upper surface of the base 1 are fixedly connected to a support frame 2, and a through hole is opened at the center of the upper end of the support frame 2, the horizontal rotation mechanism comprises a horizontal rotating shaft 3, a rotating frame 4 and a first motor 5, the rotating frame 4 is located between the two support frames 2 and the centers of both sides thereof are on the same horizontal line as the through holes on the support frame 2, there are two horizontal rotating shafts 3, both horizontal rotating shafts 3 are rotatably connected to the through holes, and the opposite ends of the two horizontal rotating shafts 3 are fixedly connected to the rotating frame 4, and the other end of one horizontal rotating shaft 3 is fixedly connected to the output rotating shaft of the first motor 5, and a splint 10 is rotatably connected to the horizontal rotating shaft 3 at the gap between the support frame 2 and the rotating frame 4 on both sides, the splint 10 is a ring plate, one side of the splint 10 is fixedly connected to the support frame 2, and the other side is rotatably connected to the rotating frame 4, so as to limit the lateral movement of the rotating frame 4, so that the device is more stable, and a fixing plate 11 is fixedly connected to the bottom of the first motor 5, and the fixing plate 11 is fixedly connected to the support frame 2;

[0023] The vertical rotation mechanism includes a second motor 6 and a rotating drum 7. The second motor 6 is fixedly connected to the center of the top surface of the rotating frame 4. The rotating drum 7 is located in the inner center of the rotating frame 4. One side of the rotating drum 7 is a rotating drum cover 13. The rotating drum cover 13 is rotatably connected to the rotating drum 7 by a hinge. A plurality of clamping blocks 14 are evenly fixedly connected to the inner surface of the rotating drum 7. The clamping blocks 14 are made of rubber. The rotating drum 7 fixes the electronic grade hydrofluoric acid packaging container in the drum body through the clamping blocks 14. Since the rubber has elasticity, the clamping blocks 14 can tightly clamp the container to be cleaned without shaking. The driving shaft 8 of the second motor 6 passes through the rotating frame 4 and is rotatably connected. It is fixedly connected to one end of the rotating cylinder 7, and the other end of the rotating cylinder 7 is fixedly connected to a vertical rotating shaft 9. The other end of the vertical rotating shaft 9 is rotatably connected to the rotating frame 4. The centers of the upper and lower inner surfaces of the rotating frame 4 are fixedly connected to a limiting ring plate 15. The centers of the opposite end surfaces of the two limiting ring plates 15 are provided with an annular groove. The two ends of the rotating cylinder 7 are rotatably connected to the surface of the annular groove. By limiting the rotation of the rotating cylinder 7 in the annular groove, the rotation process is made more stable. A counterweight block 12 is fixedly connected to the center of the bottom surface of the rotating frame 4. The weight of the counterweight block 12 is equal to that of the second motor 6, which is used to balance the mass of the second motor 6, so that the rotating frame 4 rotates more stably and smoothly.

[0024] By providing a horizontal rotation mechanism and a vertical rotation mechanism and cooperating with each other, it is possible to achieve all-round cleaning of the electronic-grade hydrofluoric acid packaging container fixed in the cylinder 7. The device is not only simple in structure, but also has good stability because the horizontal rotation mechanism and the vertical rotation mechanism are combined and supported on the support frame 2 on the base 1.

[0025] The functional principle of this utility model can be explained through the following operation modes:

[0026] During use, a sealed electronic-grade hydrofluoric acid packaging container containing cleaning liquid is placed in the cylinder body of the rotating cylinder 7, and the rotating cylinder cover 13 is covered. At this time, the rubber block 14 on the inner wall of the rotating cylinder 7 fixes the electronic-grade hydrofluoric acid packaging container in the cylinder body to the maximum extent, and the first motor 5 and the second motor 6 are started at the same time. At this time, the rotating frame 4 rotates horizontally around its axis through the horizontal rotating shaft 3, and the rotating cylinder 7 rotates vertically around its axis through the driving rotating shaft 8 on the second motor 6. Through the coordination of the horizontal rotation and the vertical rotation, a small amount of cleaning liquid can be loaded into the electronic-grade hydrofluoric acid packaging container and the inner wall of the container can be cleaned in all directions without dead angles. The device is not only simple in structure, but also has good stability because the horizontal rotation mechanism and the vertical rotation mechanism are combined and supported on the support frame 2 on the base 1.

Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
