Detailed implementation manners

[0039] In order to further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0040] See Figures 1 to 14As shown in the figure, a device for quickly cleaning test tubes for inspection using a disinfectant solution includes a cleaning box 1 and a conveyor belt 2 arranged inside the cleaning box 1; it also includes a U-shaped mounting plate 3, a positioning mechanism 4, a first hydraulic rod 5, and a disinfection mechanism 6; a plurality of strip-shaped mounting blocks 21 are equidistantly arranged on the conveyor belt 2, the length direction of the strip-shaped mounting blocks 21 is perpendicular to the conveying direction of the conveyor belt 2, and a plurality of mounting grooves 211 are arranged along the length direction on the side of each strip-shaped mounting block 21 away from the conveyor belt 2. Hinge holes 212 are arranged on the inner walls on both sides of each mounting groove 211. There are a plurality of U-shaped mounting plates 3, and hinge rods 31 are arranged on the outer walls on both sides of each U-shaped mounting plate 3. The hinge rods 31 are rotatably arranged in the corresponding hinge holes 212, and a horizontal torsion spring 311 is also arranged on each hinge rod 31; a rotating hole 213 penetrating through a plurality of mounting grooves 211 is arranged on each strip-shaped mounting block 21, and a rotating shaft 22 is rotatably arranged in each rotating hole 213; a winding wheel 312 is arranged on each hinge rod 31. A plurality of first one-way bearings 221 are arranged along the length direction of the rotating shaft 22, and a tensioning wheel 222 cooperating with the winding wheel 312 is arranged on the outer wall of each first one-way bearing 221. A winding rope 313 is connected between the tensioning wheel 222 and the winding wheel 312. Friction wheels 223 are also arranged at both ends of the rotating shaft 22, and first friction strips 11 cooperating with the friction wheels 223 are arranged on the inner walls on both sides of the disinfection box; a supporting plate 23 is also arranged at the bottom of each U-shaped mounting plate 3, and a positioning hole 32 for the test tube to pass through is arranged at the center of the bottom of each U-shaped mounting plate 3. A plurality of sliding rods 231 are arranged in a matrix distribution on the side of each supporting plate 23 close to the U-shaped mounting plate 3. The plurality of sliding rods 231 extend along the axis direction of the corresponding positioning hole 32 through the U-shaped mounting plate 3 and are provided with limiting disks 232. A return spring 233 is also sleeved on each sliding rod 231, and the return spring 233 is located inside the corresponding U-shaped mounting plate 3; there are multiple groups of positioning mechanisms 4, and the positioning mechanisms 4 are arranged inside the corresponding U-shaped mounting plates 3 and are used for clamping and fixing the test tubes. Each group of positioning mechanisms 4 includes two vertical strips 41 that can approach and move away from each other as the supporting plate 23 moves. The length direction of the vertical strips 41 is the same as the axis direction of the positioning hole 32, and a plurality of right-angle clamping strips 411 are arranged along the length direction on the facing sides of the two vertical strips 41; the first hydraulic rod 5 is arranged vertically at the bottom of the cleaning box 1, and the execution part of the first hydraulic rod 5 extends into the disinfection box and is provided with a disinfection box 51; the length direction of the disinfection box 51 is perpendicular to the conveying direction of the conveyor belt 2. A water filling hole 511 is arranged on the outer wall of one side of the disinfection box 51, and a water delivery hose 512 is arranged in the water filling hole 511. The end of the water delivery hose 512 away from the water filling hole 511 extends out of the cleaning box 1; a plurality of drain holes 513 are arranged along the length direction on the top of the disinfection box 51. The disinfection mechanism 6 is arranged on the top of the disinfection box 51 and is used for cleaning and disinfecting the fixed test tubes. The disinfection mechanism 6 includes a plurality of drain tubes 61 that can rotate self-rotation as the disinfection box 51 moves. The drain tubes 61 are communicated with the inside of the disinfection box 51 through the corresponding drain holes 513;A plurality of flushing holes 611 are provided on each drain tube 61, and brush bristles 612 are further provided on the outer wall of each drain tube 61.;

[0041] The staff sequentially places the test tubes into the positioning holes 32 of the U-shaped mounting plate 3. At this time, under the torque action of the horizontal torsion spring 311, the bottom of the U-shaped mounting plate 3 can remain horizontal with the bottom of the rectangular groove. The bottom of the test tube contacts the corresponding supporting plate 23, thereby pushing the corresponding supporting plate 23 to move. During this process, the two vertical strips 41 can approach each other as the corresponding supporting plate 23 moves. A plurality of right-angle clamping strips 411 are equidistantly arranged along the length direction of each vertical strip 41, and there is a certain gap between two adjacent right-angle clamping strips 411 (as shown), and the right-angle clamping strips 411 on the two vertical strips 41 move through the corresponding gaps, so as to be able to clamp and fix test tubes with different diameters, so that the test tubes can be coaxially arranged with the positioning holes 32, thereby ensuring the stability of the test tubes during the cleaning process. At this time, the open end of the test tube faces away from the bottom of the corresponding rectangular groove, so as to reduce the damage to the staff's body caused by the pollutants inside the test tube during the placement of the test tube. Subsequently, the conveyor belt 2 is adjusted. The strip-shaped mounting block 21 with the test tube moves into the cleaning box 1 as the conveyor belt 2 transports. At this time, the open end of the test tube faces the inside of the cleaning box 1. When the strip-shaped mounting block 21 moves above the first hydraulic rod 5, by adjusting the first hydraulic rod 5, the first hydraulic rod 5 drives the disinfection box 51 to move back and forth in the vertical direction. The external disinfectant is transported into the disinfection box 51 through the water supply hose 512. The drain tube 61 can rotate self as the disinfection box 51 moves back and forth. The disinfectant disinfects and cleans the inner wall of the test tube through a plurality of flushing holes 611 provided on the outer wall of the drain tube 61. The brush bristles 612 are spirally arranged on the outer wall of the drain tube 61. The spiral arrangement of the brush bristles 612 can not only clean the inside of the test tube but also make the disinfectant evenly distributed on the inner wall of the test tube, thereby improving the cleaning and disinfection effect of the test tube. When the disinfection is completed, the conveyor belt 2 continues to move. When the strip-shaped mounting block 21 moves to the first friction strip 11, the friction wheels 223 on both sides of the rotating shaft 22 are in frictional cooperation with the first friction strip 11, so that the rotating shaft 22 rotates. As the rotating shaft 22 rotates, the first one-way bearing 221 is driven to rotate. At this time, the tensioning wheel 222 on the first one-way bearing 221 can pull the corresponding winding wheel 312 to rotate through the winding rope 313, so that the U-shaped mounting plate 3 rotates. At this time, the horizontal torsion spring 311 generates torque due to the rotation of the U-shaped mounting plate 3. When the friction wheel 223 is separated from the first friction strip 11, under the torque action of the horizontal torsion spring 311, the entire U-shaped mounting plate 3 can quickly rotate along the axis direction of the corresponding hinge rod 31, so as to throw out the disinfectant and impurities remaining in the test tube, thereby ensuring the cleaning effect inside the test tube. Figure 6 As shown, the right-angle clamping strips 411 on the two vertical strips 41 move through the corresponding gaps, so as to be able to clamp and fix test tubes with different diameters, so that the test tubes can be coaxially arranged with the positioning holes 32, thereby ensuring the stability of the test tubes during the cleaning process. At this time, the open end of the test tube faces away from the bottom of the corresponding rectangular groove, so as to reduce the damage to the staff's body caused by the pollutants inside the test tube during the placement of the test tube. Subsequently, the conveyor belt 2 is adjusted. The strip-shaped mounting block 21 with the test tube moves into the cleaning box 1 as the conveyor belt 2 transports. At this time, the open end of the test tube faces the inside of the cleaning box 1. When the strip-shaped mounting block 21 moves above the first hydraulic rod 5, by adjusting the first hydraulic rod 5, the first hydraulic rod 5 drives the disinfection box 51 to move back and forth in the vertical direction. The external disinfectant is transported into the disinfection box 51 through the water supply hose 512. The drain tube 61 can rotate self as the disinfection box 51 moves back and forth. The disinfectant disinfects and cleans the inner wall of the test tube through a plurality of flushing holes 611 provided on the outer wall of the drain tube 61. The brush bristles 612 are spirally arranged on the outer wall of the drain tube 61. The spiral arrangement of the brush bristles 612 can not only clean the inside of the test tube but also make the disinfectant evenly distributed on the inner wall of the test tube, thereby improving the cleaning and disinfection effect of the test tube. When the disinfection is completed, the conveyor belt 2 continues to move. When the strip-shaped mounting block 21 moves to the first friction strip 11, the friction wheels 223 on both sides of the rotating shaft 22 are in frictional cooperation with the first friction strip 11, so that the rotating shaft 22 rotates. As the rotating shaft 22 rotates, the first one-way bearing 221 is driven to rotate. At this time, the tensioning wheel 222 on the first one-way bearing 221 can pull the corresponding winding wheel 312 to rotate through the winding rope 313, so that the U-shaped mounting plate 3 rotates. At this time, the horizontal torsion spring 311 generates torque due to the rotation of the U-shaped mounting plate 3. When the friction wheel 223 is separated from the first friction strip 11, under the torque action of the horizontal torsion spring 311, the entire U-shaped mounting plate 3 can quickly rotate along the axis direction of the corresponding hinge rod 31, so as to throw out the disinfectant and impurities remaining in the test tube, thereby ensuring the cleaning effect inside the test tube.

[0044] When the test tube is not placed, the supporting plate 23 fits against the bottom of the corresponding U-shaped mounting plate 3 under the elastic force of the return spring 233, and the return torsion spring 432 can keep the traction rope 44 in a taut state. When the test tube is placed at the positioning hole 32 of the U-shaped mounting plate 3, the test tube moves downward and pushes the supporting plate 23. The supporting plate 23 moves away from the bottom of the U-shaped mounting plate 3 against the elastic force of the return spring 233. As the supporting plate 23 moves, the triangular block 235 contacts the limiting strip 362 and thus pushes the limiting strip 362 to move away from the triangular block 235, thereby ensuring the stability of the movement of the supporting plate 23. During this process, the corresponding linkage shaft 43 is pulled by the two traction ropes 44 to rotate against the torsion of the return torsion spring 432. The two driving gears 431 on the linkage shaft 43 mesh with the teeth 426 on the corresponding sliding strip 42, so that the two sliding strips 42 approach each other. The multiple right-angle clamping strips 411 provided on the vertical strip 41 contact the outer wall of the test tube. As the supporting plate 23 continues to move, the two sliding strips 42 continue to approach, and the guide rod 412 on the corresponding vertical strip 41 moves toward the corresponding side. At this time, the pressing spring 425 is compressed to generate an elastic force, thereby avoiding the rigid contact between the right-angle clamping strip 411 and the test tube and causing damage to the test tube. The setting of the limiting plate 423 can limit the position of the guide rod 412 and prevent it from being pushed out of the guide hole 421 by the elastic force of the pressing spring 425. When the test tube is fixed, the triangular block 235 is engaged with the triangular groove 365 on the limiting strip 362, thereby restricting the position of the supporting plate 23 and preventing the test tube from shaking during transportation.

[0045] Specifically, the opposite ends in this application refer to the sides that are close to each other.

[0046] See Figure 5 and Figure 12 As shown, the disinfection mechanism 6 further includes a worm 62, an adjusting gear 63 and a rack 64; extension plates 52 are provided at both ends of the top of the disinfection box 51 along the length direction. Mounting holes 521 are provided on the extension plates 52. Both ends of the worm 62 are rotatably arranged in the mounting holes 521 of the corresponding extension plates 52. A worm gear 613 is provided on each drainage cylinder 61, and the worm gear 613 meshes with the worm 62. There are two adjusting gears 63, which are arranged at both ends of the worm 62 along the length direction. There are two racks 64, which are vertically arranged on the inner walls of both sides of the cleaning box 1 and respectively mesh with the corresponding adjusting gears 63.

[0047] When the first hydraulic rod 5 drives the disinfection box 51 to move back and forth in the vertical direction, the adjusting gear 63 meshes with the corresponding rack 64, thereby driving the worm 62 to rotate. The worm 62 meshes with the worm wheels 613 on multiple drainage cylinders 61, thereby synchronously driving the multiple drainage cylinders 61 to rotate, enabling the drainage cylinders 61 to move back and forth and rotate within the test tubes, so as to comprehensively clean and disinfect the inner walls of the test tubes.

[0048] See Figure 1 , Figure 3 , Figure 13 and Figure 14As shown, after cleaning is completed, the staff needs to take out the cleaned test tubes. Based on this situation, a discharge mechanism 7 is provided on the top of the cleaning box 1, which can take out the sterilized test tubes from the U-shaped mounting plate 3; the discharge mechanism 7 includes a U-shaped plate 71, a second hydraulic rod 72, a horizontal plate 73 and a driving rod 74; the U-shaped plate 71 is arranged on the top of the rectangular mounting frame, and the inner walls on both sides of the U-shaped plate 71 are provided with placement plates 711, there are two second hydraulic rods 72, and the second hydraulic rods 72 are arranged in a vertical state on the corresponding placement plates 711, and a guide rail 721 is provided on the actuator of each second hydraulic rod 72, and the length direction of the guide rail 721 is the same as the conveying direction of the conveyor belt 2, and each guide rail 721 has a plurality of guide rails 721. A threaded rod 722 is rotatably provided, and the length direction of the threaded rod 722 is the same as the length direction of the guide rail 721; the horizontal plate 73 is arranged in a horizontal state, and sliding blocks 731 are arranged at both ends of the horizontal plate 73 along the length direction, and the sliding blocks 731 are slidably arranged in the corresponding guide rail 721 and are threadedly connected with the corresponding threaded rod 722, and a strip-shaped groove 712 for avoiding the horizontal plate 73 is arranged on the top of the 匚-shaped plate 71; vertical plates 732 are arranged at both ends of the top of the horizontal plate 73 along the length direction, and each vertical plate 732 is provided with an adjustment hole 7321, and both ends of the driving rod 74 are rotatably arranged in the corresponding adjustment hole 7321, and the horizontal plate 73 is provided with a plurality of strip grooves along the length direction. 733, each strip-shaped slide groove 733 is slidably provided with two clamping plates 734, and the driving rod 74 is provided with multiple groups of threaded parts 741 along the length direction, and each clamping plate 734 is provided with a threaded hole 7341 at the top, and the threaded hole 7341 is connected to the corresponding threaded part 741 on the driving rod 74; the 匚-shaped plate 71 is also provided with a plurality of strip-shaped receiving grooves 713 for placing test tubes, and the plurality of strip-shaped receiving grooves 713 are connected to the strip-shaped missing grooves 712, and the length direction of the strip-shaped receiving grooves 713 is the same as the length direction of the guide rail 721, and a plurality of cross-clip strips 714 are rotatably provided on both sides of the top of each strip-shaped receiving groove 713; the inner wall at the bottom of each mounting groove 211 is provided with two vertical slide rails 214, and the two vertical The slide rails 214 are located on both sides of the rotating shaft 22 along the length direction. A trapezoidal abutment block 215 for moving the two limit bars 362 away from each other is further provided between the two vertical slide rails 214. Z-shaped connection blocks 216 are provided on both sides of the trapezoidal abutment block 215. One end of each Z-shaped connection block 216 away from the trapezoidal abutment block 215 is slidably provided in the corresponding vertical slide rail 214. A vertical rod 2141 is provided in each vertical slide rail 214. A vertical hole 2161 for avoiding the vertical rod 2141 is provided on each Z-shaped connection block 216. A downward pressure spring 2142 is further provided on each vertical rod 2141. The downward pressure spring 2142 is located between the corresponding Z-shaped connection block 216 and the inner wall at the top of the vertical slide rail 214.A bearing seat 217 is provided at the center of the inner wall at the bottom of each mounting groove 211, and a plurality of second one-way bearings 224 are provided along the length direction of the rotating shaft 22. An L-shaped abutment rod 225 for pushing the trapezoidal abutment block 215 is provided on the second one-way bearing 224. Second friction strips 715 cooperating with the friction wheel 223 are also provided on the inner walls of both sides of the 匚-shaped plate 71. ;

[0049] When the strip-shaped mounting block 21 moves to the first friction strip 11, the friction wheels 223 at both ends of the rotating shaft 22 come into contact with the first friction strip 11, thereby driving the rotating shaft 22 to rotate. Due to the provision of the second one-way bearing 224, the L-shaped abutting rod 225 will not rotate due to the rotation of the rotating shaft 22. At this time, under the elastic force of the pressing spring 2142, the bottom of the trapezoidal abutting block 215 contacts the bearing seat 217, thereby preventing the trapezoidal abutting block 215 from generating a volume collision with the two vertical strips 41. When the strip-shaped mounting block 21 moves into the C-shaped plate 71 along with the conveyor belt 2, the friction wheel 223 contacts the second friction strip 715, thereby driving the rotating shaft 22 to rotate in the opposite direction. Due to the action of the first one-way bearing 221, it will not drive the U-shaped mounting plate 3 to rotate by pulling the winding rope 313, thereby ensuring the stability of the test tube placed on the U-shaped mounting plate 3. As the rotating shaft 22 continues to rotate, the L-shaped abutting rod 225 is driven to rotate through the second one-way bearing 224. The L-shaped abutting rod 225 contacts the trapezoidal abutting block 215, thereby pushing the trapezoidal abutting block 215 to move towards the corresponding supporting plate 23. The trapezoidal abutting block 215 contacts the two limiting strips 362, so that the two limiting strips 362 can move away from each other against the elastic force of the corresponding pressing spring 364. Under the elastic force of the reset spring 233, the supporting plate 23 pushes the test tube to move. At this time, the reset torsion springs 432 at both ends of the linkage shaft 43 can drive the linkage shaft 43 to rotate, so that the two vertical strips 41 can move away from each other by a certain distance, separating the right-angle clamping strips 411 from the outer wall of the test tube. Subsequently, by adjusting the second hydraulic rod 72, the second hydraulic rod 72 drives the guide rail 721 to move downward, so that the test tube is located between the two clamping plates 734 in the same strip-shaped chute 733. One of the vertical plates 732 is provided with a first servo motor 7322 for adjusting the rotation of the driving rod 74. The staff adjusts the first servo motor 7322, and the first servo motor 7322 drives the driving rod 74 to rotate. Each thread part 741 is composed of two threads with opposite directions. The threaded holes 7341 on the two vertical plates 732 located in the strip-shaped chute 733 are respectively connected to the threads on the corresponding threaded rods 722, so that the two clamping plates 734 located in the same strip-shaped chute 733 can approach each other to fix the test tube. Subsequently, the second hydraulic rod 72 drives the two guide rails 721 to move vertically upward. Each guide rail 721 is also provided with a second servo motor 723 for driving the threaded rod 722 to rotate. By adjusting the two second servo motors 723, the test tube fixed by the two clamping plates 734 is moved along the length direction of the corresponding strip-shaped receiving groove 713. The multiple cross-shaped clamping strips 714 along the length direction of the strip-shaped receiving groove 713 are arranged in a wavy shape and staggered. The multiple cross-shaped clamping strips 714 can divide the strip-shaped receiving groove 713 into multiple spaces for accommodating test tubes. When the test tube is placed, adjust the first servo motor 7322,Thereby, the two clamping plates 734 move away from each other, facilitating the continuous removal of the test tubes.

[0050] See Figure 5 As shown, an ultraviolet lamp 12 is further provided in the cleaning box 1, and the ultraviolet lamp 12 is located below the first friction strip 11.

[0051] After the friction wheel 223 contacts the first friction strip 11, as the conveyor belt 2 continues to move, the friction wheel 223 drives the rotating shaft 22 to rotate. The rotating shaft 22 pulls the U-shaped mounting plate 3 to rotate through the winding rope 313. Multiple ultraviolet lamps 12 can perform a comprehensive secondary disinfection on the test tubes during the slow rotation of the test tubes, thereby further improving the disinfection effect of the test tubes.

[0052] See Figure 3 As shown, a drain pipe 13 is provided on the side of the cleaning box 1 away from the water supply hose 512, and a manual valve 14 is provided on the drain pipe 13.

[0053] The staff adjusts the manual valve 14 to open the drain pipe 13, facilitating the staff to drain the contaminated disinfectant liquid inside the cleaning box 1.

[0054] See Figure 8 As shown, a buffer pad 236 is provided at the center of one side of each support plate 23 close to the corresponding U-shaped mounting plate 3.

[0055] By providing the buffer pad 236, the rigid contact between the bottom of the test tube and the support plate 23 can be avoided, ensuring the integrity of the test tube.
