[0022] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0023] like Figure 1 As shown, a medical device inspection and packaging workbench includes a main frame 4, with the upper horizontal surface of the main frame 4 serving as a working surface 2. An operating frame 1 is vertically mounted on the rear side of the working surface 2. Figure 4 The operating frame 1 includes a frame 22 that is vertically fixed to the surface of the working surface 2. A camera 19 is installed at the top center of the frame 22 for filming the packaging process of the working surface 2.

[0024] Vertically within the frame 22, multiple storage areas are spaced apart by partitions 18, each containing a storage basket 20 and a storage box 21. A screen bracket 23 is mounted on a pillar on one side of the frame 22, securing a touchscreen to the packaging process. This allows for status display and control, such as controlling the camera 19. A power socket 24 is also located on the pillar of the frame 22. The power socket 24, the camera 19, and the touchscreen's power and data cables are routed internally within the frame 22.

[0025] An operating area is located in the center of the working surface 2, with camera 19 facing downwards towards the operating area. A sensing area and a weighing area are located on either side of the operating area. An RFID card reader is installed in the sensing area for reading the instrument's card. A weighing box 3, symmetrically positioned over the weighing area, is located at the bottom of the working surface 2. A weighing mechanism is installed inside the weighing box 3, with its weighing surface either higher than or flush with the working surface 2.

[0026] Combination Figures 2-3 The weighing mechanism housed within the weighing box 3 includes a weighing base plate 9. An electric push rod 5 is mounted on the surface of the weighing base plate 9, and guide components 6 are located on both sides of the electric push rod 5. The electric push rod 5 enables the lifting and lowering of the weighing surface of the weighing mechanism, and the guide components 6 guide the lifting and lowering of the weighing surface during operation. A leveling mechanism is installed on the bottom surface inside the weighing box 3, and the weighing base plate 9 is fixed inside the weighing box 3 via the leveling mechanism.

[0027] The leveling mechanism includes multiple fixed seats 8 fixed to the bottom surface of the weighing box 3. The fixed seats 8 are arranged in a triangular or rectangular shape, and all fixed seats 8 are located within the projection area of ​​the weighing base plate 9 in the vertical direction. A fixing bolt 10 is installed through the middle of each fixed seat 8. The fixing bolt 10 passes through the bottom plate of the weighing box 3 and the corresponding fixed seat 8 from the bottom of the weighing box 3 upwards, and then passes through the surface of the weighing base plate 9.

[0028] A fixing nut 7 is provided on the surface of each fixing seat 8. The fixing nut 7 is threadedly connected to the corresponding fixing bolt 10, thereby fixing the fixing bolt 10 to the fixing seat 8. Two adjusting nuts 11 are also threadedly connected to the upper part of each fixing bolt 10. The two adjusting nuts 11 are located at the upper and lower parts of the weighing base plate 9, respectively. By adjusting the relative position of the two adjusting nuts 11 and the corresponding fixing bolt 10, the distance between the weighing base plate 9 and the bottom surface of the weighing box 3 can be adjusted.

[0029] The guide assembly 6 includes two guide rail brackets 17 disposed on both sides of the upper surface of the weighing base plate 9, with the two guide rail brackets 17 arranged opposite to each other. An integral guide rail 15 is disposed on the inner side of each of the two guide rail brackets 17, and a slider is slidably disposed on the surface of each guide rail 15. A lifting frame 14 is disposed between the two guide rail brackets 17, with both sides of the lifting frame 14 fixed to the sliders on both sides. A weighing base frame 16 is horizontally disposed on the top of the lifting frame 14.

[0030] An electric push rod 5 is also provided on the surface of the weighing base plate 9. The electric push rod 5 is located inside the lifting frame 14. The piston rod of the electric push rod 5 is vertically upward, and the top of the electric push rod 5 is fixed to the bottom of the weighing base 16. A weighing sensor 13 is provided on the upper surface of the weighing base 16. A weighing top frame 12 is fixed on the surface of the weighing sensor 13. The upper surface of the weighing top frame 12 is the weighing surface of the weighing mechanism.

[0031] An opening corresponding to the surface of the weighing top frame 12 is provided on the surface of the working surface 2. The weighing top frame 12 is embedded in the opening. The weighing top frame 12 protrudes from the surface of the working surface 2 or is flush with the surface of the working surface 2 under the drive of the electric push rod 5.

[0032] The specific working process and working principle are as follows: By rotating the two adjusting nuts 11 on each fixing bolt 10, the horizontal state of the weighing base plate 9 is adjusted, and the horizontal state of the weighing surface is further adjusted so that the weighing surface is parallel to the working surface 2.

[0033] During operation, the electric push rod 5 is controlled to move according to the volume of the package. When the projected area of ​​the package is greater than the surface area of ​​the weighing surface, the piston rod of the electric push rod 5 is controlled to output. At this time, under the guidance of the guide component 6, the electric push rod 5 pushes the weighing base frame 16 to rise, further making the weighing surface of the weighing top frame 12 higher than the working surface 2, so as to facilitate the weighing of larger packages.

[0034] When the projected area of ​​the packaged item is smaller than the surface area of ​​the weighing surface, the piston rod of the electric push rod 5 is controlled to output. At this time, under the guidance of the guide component 6, the electric push rod 5 pushes the weighing base frame 16 to descend, so that the weighing surface of the weighing top frame 12 is lower than or flush with the working surface 2.

[0035] After the packaged item is placed on the weighing surface, the weighing sensor 13 located below the weighing top frame 12 weighs the packaged item and outputs the weighing data. The output of the weighing sensor 13 data and the subsequent data acquisition are common knowledge in the field and will not be described in detail here.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
