Description

Technical Field

[0001] This utility model relates to a transfer device, and more particularly to a sample transfer device. Background Technology

[0002] Currently, testing centers in industries such as steel and metallurgy widely use sealed sample barrels to transport and transfer samples via conveyor lines. Sometimes, due to limitations such as site conditions, it is necessary to move the sample barrels from one conveyor line to another. Manual handling is obviously impractical and inconsistent with the trend of automated testing. However, some existing sealed sample barrel transfer devices use a turret-type rotary transfer method, which has a complex structure and occupies a large space. Other transfer devices use the addition of elevators and conveyors, that is, two elevators are used to lift and place the sample barrels, and a conveyor is used for intermediate transfer. This method significantly increases the manufacturing cost, and the use and maintenance costs are also correspondingly higher. Summary of the Invention

[0003] The purpose of this invention is to provide a sample transfer device with a reasonable structure, an internal locking barrel structure, reliable barrel locking, and automatic transfer.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution. A sample transfer device includes a gantry frame, a geared motor, a moving base, a gear, a rack, a slider, a linear guide, a lifting assembly, a barrel locking assembly, and a control system. The rack and linear guide are fixed to the gantry frame, the geared motor is fixed to the moving base, the slider is fixed below the moving base and slides with the linear guide, the lifting assembly is fixed below the moving base, the gear is located on the output shaft of the geared motor and meshes with the rack, and the barrel locking assembly is located below the lifting assembly. The geared motor, the lifting assembly, and the barrel locking assembly are respectively connected to the control system.

[0005] The sample transfer device includes a lifting assembly comprising a fixed frame, a lifting cylinder, an upper plate, a guide column, a spring, and a lower plate. The upper part of the fixed frame is connected to the movable seat, and the lower part is connected to the lifting cylinder. The upper plate is connected to the piston of the lifting cylinder. The spring is fitted into the guide column. The upper plate and the lower plate are connected through the guide column. The lifting cylinder is connected to the control system.

[0006] The sample transfer device includes a locking barrel assembly comprising a cover plate, a housing, a rotary cylinder, a cylinder seat, a rotating plate, a pin, and a locking tongue. The upper end of the cover plate is connected to the lower plate, and the lower end is connected to the housing. The cylinder seat is installed inside the housing, the rotary cylinder is fixed on the cylinder seat, the rotating plate is connected to the rotary cylinder, one end of the pin is located on the locking tongue, and the other end engages with an arc-shaped groove on the rotating plate. The locking tongue is located on the locking tongue guide hole of the housing, and the rotary cylinder is connected to the control system.

[0007] Compared with the prior art, this utility model has the following advantages: (i) the use of gear and rack meshing drive + linear guide slider guide makes the locked sample barrel move at a uniform speed and smoothly; (ii) the lifting assembly adopts a combination of guide column and spring structure, which makes the lock enter and exit the sample barrel opening more buffered and avoids impacting the sample barrel; (iii) the use of internal locking structure to lock the sample barrel from the inner wall of the sample barrel opening makes the locking mechanism more compact and the locking more reliable; (iv) the locking tongue end of the locking barrel assembly is provided with a silicone bushing, which can effectively protect the inner wall of the sample barrel; (v) the use of gantry frame makes the device easier to disassemble and assemble, and can be easily installed in different areas and sites to adapt to different working conditions.

[0017] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0018] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the sample transfer device includes a gantry frame 1, a reduction motor 2, a moving seat 3, a gear 4, a rack 5, a slider 6, a linear guide 7, a lifting assembly 8, a locking assembly 9, and a control system. The rack 5 and the linear guide 7 are fixed on the gantry frame 1, the reduction motor 2 is fixed on the moving seat 3, the slider 6 is fixed below the moving seat 3 and slides with the linear guide 7, the lifting assembly 8 is fixed below the moving seat 3, the gear 4 is located on the output shaft of the reduction motor 2 and meshes with the rack 5, and the locking assembly 9 is located below the lifting assembly 8. The reduction motor 2, the lifting assembly 8, and the locking assembly 9 are respectively connected to the control system.

[0019] like Figure 5 As shown, the lifting assembly 8 includes a fixed frame 10, a lifting cylinder 11, an upper plate 12, a guide column 13, a spring 14, and a lower plate 15. The upper part of the fixed frame 10 is connected to the movable seat 3, and the lower part is connected to the lifting cylinder 11. The upper plate 12 is connected to the piston of the lifting cylinder 11. The spring 14 is fitted into the guide column 13. The upper plate 12 and the lower plate 15 are connected through the guide column 13. The lifting cylinder 11 is connected to the control system.

[0020] like Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the lock barrel assembly 9 includes a cover plate 16, a housing 17, a rotary cylinder 18, a cylinder seat 19, a rotating plate 20, a pin 21, and a locking tongue 22. The upper end of the cover plate 16 is connected to the lower plate 15, and the lower end is connected to the housing 17. The cylinder seat 19 is installed inside the housing 17. The rotary cylinder 18 is fixed on the cylinder seat 19. The rotating plate 20 is connected to the rotary cylinder 18.

Guided by the slider 6 and the linear guide 7, it moves horizontally with the lifting assembly 8 and the barrel locking assembly 9 above the sample barrel on the conveyor line. The lifting cylinder 11 of the lifting assembly 8 extends the barrel locking assembly 9 into the opening of the sample barrel through the lower plate 15. After the barrel locking assembly 9 enters the sample barrel, the rotating cylinder 18 drives the rotating plate 20 to rotate at a certain angle. During rotation, the arc-shaped groove 23 on the rotating plate 20 drives the corresponding pin 21 to move linearly. The pin 21 then drives the locking mechanism fixed to it. The tongue 22 moves linearly, extending out of the housing 17 through the guide hole of the locking tongue 22 and pressing against the inner wall of the sample barrel to lock the sample barrel. After locking, the lifting assembly 8 and the lifting cylinder 11 drive the locking barrel assembly 9 to rise and disengage from the conveyor line. The reduction motor 2 drives the moving seat 3 to move horizontally according to the program instructions through the meshing of the gear 4 and the rack 5. The moving seat 3 drives the lifting assembly 8, the locking barrel assembly 9 and the sample barrel to be transferred to the upper part of another conveyor line. The lifting assembly 8 descends and the sample barrel is placed into the conveyor line.
