In some embodiments, the working surface 31 can also be set to other shapes, the number of legs 32 is not limited to four, and the position of the legs 32 is not limited to the corner position of the working surface 31 (referring to the right angle of the rectangular working surface), and the legs 32 can also be set at other positions at the bottom of the working surface 31, as long as it does not affect the placement of the cleaning basket 5 below. This embodiment does not limit the specific structural form of the shelf 3.

[0040] Preferably, if Figure 1As shown, a positioning hole 311 (not a through hole, but a blind hole) is provided on the upper surface of the working surface 31, and a positioning pin 321 is provided at the bottom of each leg 32, and multiple shelves 3 are positioned by plugging and positioning the positioning pins 321 and the positioning holes 311. In this embodiment, the structure of the shelves 3 is simple, and the shelves 3 are plugged and positioned, which is convenient for simplifying the working procedures of the robot arm 4, reducing the working difficulty of the robot arm 4, and is conducive to improving the efficiency of automated cleaning. In addition, the technician can set the depth of the positioning hole 311 as needed, and this embodiment does not limit this.

[0041] In some embodiments, the base 1 may also be provided with a base positioning hole (not shown in the figure), so that the legs 32 of the shelves 3 adjacent to the base 1 can be positioned in the base positioning hole, ensuring that the shelves 3 and the base 1 are aligned in the vertical direction when the subsequent shelves 3 are stacked, thereby improving the stability of the cleaning load rack. In some embodiments, the base 1 may not be provided with a base positioning hole, which is not limited in this embodiment.

[0042] In a preferred embodiment of the utility model, the working surface 31 includes a frame 312 and a rigid support net (not shown in the figure) arranged in the frame 312. Furthermore, the frame 312 includes support beams and support longitudinal beams that are arranged to form a rectangular space to improve the structural stability of the shelf 3. Preferably, the support beams and support longitudinal beams are round steel with a diameter of 5 mm, and the length of the support beams is not greater than the length of the base 1, and the length of the support longitudinal beams is not greater than the width of the base 1. In some embodiments, the frame 312 can also be made of steel structures or metal structures of other shapes, which is not limited in this embodiment. In this embodiment, the rigid support net can ensure that the sprayed cleaning liquid flows down through the mesh structure, which is beneficial to improving the cleaning effect, while taking into account the strength of the working surface 31, and providing reliable support for the cleaning basket 5 placed thereon and the equipment to be cleaned in the cleaning basket 5.

[0043] In a preferred embodiment of the present invention, the number of the plurality of shelves 3 is no more than four, such as 2, 3 or 4. By controlling the number of shelves 3 within a reasonable range, the working stroke of the robot arm 4 can be reduced, and the difficulty of operation can be reduced.

[0044] Continue reading Figure 1 , Figure 3As shown, in order to further improve the stacking stability of the shelves 3, the water supply channel 2 includes multiple groups of hanging rods 21, which are spaced apart along the vertical direction of the water supply channel 2, and each group of hanging rods 21 includes two hanging rods 21 respectively fixed to both sides of the vertical direction of the water supply channel 2. Each shelf 3 includes a connecting member 33, which is respectively arranged on one side of each shelf 3 facing the water supply channel 2, and the connecting member 33 includes two wing plates 331 arranged in parallel, each wing plate 331 is vertically fixed to the working surface 31, and each wing plate 331 is provided with a slot 3311 opening downward, and the slot 3311 is correspondingly engaged with the hanging rod 21.

[0045] In the above manner, the robot arm 4 can extend under the shelf 3 and move the shelf 3, so that the shelf 3 and the water supply channel 2 are positioned in the vertical direction through the engagement of the hanging rod 21 with the slot 3311 of the connecting piece 33, thereby improving the structural stability of the cleaning load rack and ensuring the stable progress of the cleaning work.

The connection relationship between the cleaning machine and the water supply channel 2 is a common application form in this field and will not be repeated here); a water inlet pipe 34 and a spray mechanism 35 connected to the water inlet pipe 34 are fixed under each shelf 3, and the water inlet of the water inlet pipe 34 passes through the through hole 3321 and matches with the water outlet hole 22. Figure 3 The size relationship between the water inlet pipe 34 and the through hole 3321 is only for illustration and does not represent the actual size relationship. The outer diameter of the water inlet pipe 34 may be slightly smaller than the inner diameter of the through hole 3321.

[0051] Specifically, the mechanical arm 4 drives the shelf 3 to move to the top of the base 1, and when the slot 3311 is engaged with the hanging rod 21, the water inlet of the water inlet pipe 34 passes through the through hole 3321 and matches and docks with the water outlet hole 22 of the water supply channel 2, that is, when the shelf 3 moves relative to the water supply channel 2 to the slot 3311 and the hanging rod 21, the water inlet pipe 34 matches and docks with the water outlet hole 22 to achieve waterway connectivity. The water outlet of the water supply channel 2 can enter the spray mechanism 35 through the water inlet pipe 34 to ensure the normal spray cleaning. And no other structure is required to connect the water inlet pipe 34 and the water supply channel 2, the structure is simple, and it is conducive to cost saving. In addition, the inner wall of the through hole 3321 provides support for the water inlet pipe 34, thereby improving the structural stability of the water inlet pipe 34; the water inlet pipe 34 and the working surface 31 can also be fixed by other means, which is not limited in this embodiment. It should be noted that the length of the water inlet of the water inlet pipe 34 should be controlled within a reasonable range to ensure that the shelf 3 is snapped into place with the hanging rod 21 when it moves downward, that the shelf 3 is separated from the water outlet 22 when it moves upward and separates from the water supply channel 2, and that no water leakage occurs when the water inlet is connected to the water outlet 22.

[0052] In this embodiment, the spray arm of the spray mechanism 35 is provided with a hole structure, so that water can be sprayed upward and downward at the same time to clean the medical devices placed in the cleaning basket 5 on the shelf 3. The specific structure can refer to the common medical spray cleaning mechanism on the market, and this embodiment will not be repeated. In addition, the structure of the base 1 and the water supply channel 2 is also a common application form in this field, and will not be repeated here.

[0053] In some embodiments, a blocking mechanism may also be provided at the water outlet 22 to block the water outlet 22 that is not connected to the corresponding rack 3; the operator may select the number of racks 3 to be stacked according to actual needs, and block the unused water outlet 22 to save water. In some embodiments, a sealing structure may be provided between the water outlet 22 and the water inlet of the water inlet pipe 34 to prevent water from overflowing from the docking point. Preferably, the inner diameter of the water outlet 22 is the same as the inner diameter of the water inlet of the water inlet pipe 34 or the inner diameter of the water outlet 22 is larger than the inner diameter of the water inlet of the water inlet pipe 34; when the inner diameter of the water outlet 22 is larger than the inner diameter of the water inlet of the water inlet pipe 34, the water inlet pipe 34 can still match and dock with the water outlet 22 when an installation deviation occurs, and the surface of the web 332 can block the part where the water outlet 22 is not docked with the water inlet of the water inlet pipe 34 to prevent water from overflowing.

[0054] In this embodiment, the cleaning machine includes a conveying mechanism (not shown in the figure), and the cleaning load rack is conveyed into or out of the cleaning machine by the conveying mechanism, and the rack 3 is conveyed on the conveying mechanism. Before the cleaning load rack is conveyed to the cleaning machine, the cleaning basket 5 is placed on the rack 3 by the mechanical arm 4, and the rack 3 is stacked by the mechanical arm 4. After the stacking is completed, the cleaning load rack is further conveyed to the inside of the cleaning machine by the conveying mechanism, and the cleaning machine supplies water to the water supply channel 2 by connecting with the water supply channel 2 for spray cleaning; the connection between the cleaning load rack and the cleaning machine to realize water supply is a common application form in this field, which will not be repeated here. After cleaning, the cleaning load rack leaves the cleaning machine through the conveying mechanism, and the load rack leaving the cleaning machine remains on the conveying mechanism. When multiple racks 3 are removed by the mechanical arm 4, the cleaning basket 5 is removed together with the corresponding rack 3, and the cleaning basket 5 can be taken out separately by the mechanical arm 4, realizing the automatic operation of taking and putting the cleaning basket 5, and improving the cleaning efficiency. The conveying mechanism can be a chain conveying mechanism, and the conveying mechanism includes a motor, and the chain transmission is driven by the motor to control the load rack to enter or leave the cleaning machine.
