DETAILED DESCRIPTION

[0028] See also Figure 1-Figure 10 The present invention provides a technical solution: a smear device for clinical testing in a laboratory, comprising a centrifuge body 1 and a slide clamp 2. A first conveyor 3 is arranged on the right side of the centrifuge body 1. A plurality of positioning frames 4 are fixedly installed on the conveyor belt surface of the first conveyor 3. The slide clamp 2 is placed inside the positioning frame 4. A U-shaped frame 5 is arranged on the front side of the centrifuge body 1. Two mounting boxes 6 are fixedly installed on the bottom of the rear end of the U-shaped frame 5. A loading mechanism is arranged at the bottom end of the right mounting box 6. The loading mechanism is used to symmetrically place the slide clamps 2 at the top of the first conveyor 3 in the centrifuge body 1 in pairs. A discharging mechanism is arranged at the bottom end of the left mounting box 6. The discharging mechanism is used to take the slide clamp 2 out of the centrifuge body 1 and separate the glass slide from the slide clamp 2. A driving mechanism is arranged at the front end of the U-shaped frame 5. The driving mechanism is used to provide power for the movement of the U-shaped frame 5.

[0029] The feeding mechanism includes a first sliding block 7 which is slidably connected to the inner side of the right end of the right installation box 6 through a tension spring, and a rotating rod 8 is rotatably connected to the bottom end of the first sliding block 7. The bottom end of the rotating rod 8 and the bottom of the left end of the right installation box 6 are fixedly installed with a first clamping box 9, and the inner side of the bottom end of the first clamping box 9 is slidably connected with two first clamping plates 10 through a compression spring. A rotating mechanism is provided at the front end of the right installation box 6, and the rotating mechanism is used to drive the right first clamping box 9 to rotate half a circle when the right installation box 6 is removed from the top of the first conveyor 3. A first limiting plate 11 is fixedly installed at the rear end of the first conveyor 3, and a first L-shaped rod 12 is slidably connected to the middle part of the first limiting plate 11, and the bottom end of the first L-shaped rod 12 is connected to the first limiting plate 11 through a tension spring. A releasing mechanism is provided at the bottom end of the right installation box 6, and the releasing mechanism is used to drive the two adjacent first clamping plates 10 to move away from each other when the right installation box 6 moves to the inside of the centrifuge body 1, and an electric rotary wheel 13 is installed at the front end of the right installation box 6;

[0030] During operation, the assembled film-making clamps 2 are placed one by one in the positioning frame 4 at the top of the first conveyor 3, and the driving mechanism is started to drive the U-shaped frame 5 to move right, and the U-shaped frame 5 moves to the right, driving the two installation boxes 6 to move to the right synchronously. During the movement of the right installation box 6 to the right, the first L-shaped rod 12 blocks the right first clamping box 9, so that the right first clamping box 9 moves to the left compared to the right installation box 6. When the U-shaped frame 5 can no longer move to the right, the bottom ends of the two adjacent groups of first clamping plates 10 correspond to the top ends of the two film-making clamps 2 at the left end respectively, and then the driving mechanism drives the U-shaped frame 5 to move downward, and the U-shaped frame 5 moves downward, driving the two installation boxes 6 to move downward, and the right installation box 6 moves downward, driving the first clamping plate 10 to move downward, and the first clamping plate 10 is squeezed by the top end of the film-making clamp 2 during the downward movement, so that the two adjacent first clamping boxes The plates 10 move away from each other until the top of the film making clamp 2 is clamped between the two adjacent first clamping plates 10, and the driving mechanism drives the U-shaped frame 5 and the installation box 6 to move upward, and the installation box 6 moves upward to restore to the initial height and then moves to the left. During the movement of the installation box 6 to the left, the rotating mechanism drives the first clamping box 9 on the right to rotate half a circle, and the first slider 7 slowly returns to the initial position under the pull of the tension spring. At this time, the two film making clamps 2 at the bottom end of the right installation box 6 are in a symmetrical state, so that it is convenient to place the film making clamps 2 symmetrically in the centrifuge body 1 in pairs later, and at the same time avoid that when the number of remaining film making clamps 2 is small, the remaining film making clamps 2 can be placed in the centrifuge body 1 in a symmetrical state, so that the center of gravity of the rotor in the centrifuge body 1 will not shift, thereby ensuring that the centrifugal smear operation of the film making clamp 2 is more standardized and accurate, and the accuracy of the test results is increased;

[0031] When the right installation box 6 moves to the initial position, the driving mechanism drives the installation box 6 to move downward, and this operation is the unloading operation of the left installation box 6, which is described in detail below; when the installation box 6 moves upward again and returns to the initial position, the driving mechanism drives the right installation box 6 to move to the left and downward into the inner side of the centrifuge body 1 through the U-shaped frame 5, and when the two film-making clips 2 at the bottom end of the right installation box 6 are symmetrically placed in the slots of the centrifuge body 1, the release mechanism drives the two adjacent first clamping plates 10 to move away from each other, and at this time the film-making clips 2 fall into the slots of the centrifuge body 1 and are placed, thereby realizing the automatic pick-and-place operation of the film-making clips 2, and no manual operation is required by the staff during the operation, which greatly improves the operating efficiency; when a group of film-making clips 2 are placed, the electric runner 13 starts to drive the rotor inside the centrifuge body 1 to rotate a certain angle, so that the two empty slots are rotated to the left and right sides of the rotor, and the reciprocating operation is cyclically repeated until the slots in the centrifuge body 1 are all placed, and at this time the U-shaped frame 5 and the installation box 6 return to the initial position, and the centrifuge body 1 starts to perform the centrifugal smear operation;

[0032] When the centrifugal smear is completed, the driving mechanism starts again to drive the U-shaped frame 5 to move to the right. Similarly to the above, when the U-shaped frame 5 moves downward for the first time, the right-side mounting box 6 performs the material clamping operation, and the left-side mounting box 6 goes deep into the centrifuge body 1. At this time, the unloading mechanism clamps the slide making clamps 2 at the left and right ends. When the right-side mounting box 6 returns to its initial position and moves downward, the left-side mounting box 6 clamps and takes out the two slide making clamps 2 from the centrifuge body 1 through the unloading mechanism, and discards the slide making clamp 2. At this time, the glass slide inside the slide making clamp 2 is still clamped at the bottom end of the left-side mounting box 6. When the right-side mounting box 6 extends into the centrifuge body again, 1, the left installation box 6 drives the two glass slides to move to the left and store them neatly. The reciprocating operation realizes the operation of unloading from the centrifuge body 1 and loading new materials at the same time, which greatly reduces the operation steps and further improves the inspection efficiency. By setting the unloading mechanism, the slide making clamp 2 automatically separates and stores the glass slides during the process of being taken out, thereby greatly reducing the workload of the staff, and bringing convenience to the subsequent observation and inspection operations, increasing the practicality of the device, and solving the problem that the existing smear equipment for clinical inspection in the laboratory is simple in structure and difficult to realize automatic smear induction of samples.

[0033] As a further solution of the present invention, the release mechanism includes a serpentine rod 14 arranged at the lower side of the front end of the right mounting box 6, two first limit rods 15 are fixedly installed at the top of the serpentine rod 14, two first mounting rings 16 are fixedly installed at the front end of the right mounting box 6, the top ends of the first limit rods 15 pass through the first mounting rings 16 and are slidably connected thereto, the front ends of the first clamping plates 10 are fixedly installed with first push plates 17, and two first trapezoidal plates 18 are fixedly installed at the top of the serpentine rod 14, and the first trapezoidal plates 18 correspond to the bottom ends of the two adjacent first push plates 17;

[0034] During operation, the right side mounting box 6 goes down to the inner side of the centrifuge body 1. At this time, the right end of the serpentine rod 14 is blocked by the top of the right end of the centrifuge body 1, so that the serpentine rod 14 moves upward compared to the mounting box 6. At this time, the serpentine rod 14 pushes the two first trapezoidal plates 18 to squeeze the first push plate 17. The two adjacent first push plates 17 are squeezed away from each other by the inclined surface of the first trapezoidal plate 18, thereby loosening the film-making clamp 2 and allowing the film-making clamp 2 to fall into the slot hole on the inner side of the centrifuge body 1.

[0035] As a further solution of the present invention, the rotating mechanism includes a gear 19 fixedly mounted on the outer side of the rotating rod 8, and a rack 20 is fixedly mounted on the bottom of the front end of the right mounting box 6, and the rack 20 corresponds to the front end of the gear 19;

[0036] During operation, when the right-side mounting box 6 moves to the left from the top of the first conveyor 3, the first slider 7 and the right-side first clamping box 9 are no longer blocked by the first L-shaped rod 12, and move to the right relative to the mounting box 6 under the pull of the tension spring. The first slider 7 drives the gear 19 to move to the right during the movement to the right. The gear 19 drives the right-side film-making clamp 2 to rotate half a circle driven by the rack 20 during the movement to the right, so that the two film-making clamps 2 at the bottom end of the right-side mounting box 6 are in a symmetrical state, preparing for the subsequent placement of the film-making clamps 2.

[0037] As a further solution of the present invention, the unloading mechanism includes a second slider 21 slidably connected to the inner side of the left end of the left installation box 6 through a tension spring, a second clamping box 22 is fixedly installed on the bottom end of the second slider 21 and the bottom of the right end of the left installation box 6, and two second clamping plates 23 are slidably connected to the inner side of the bottom end of the second clamping box 22 through a compression spring, and a discharging mechanism is arranged at the front end of the left installation box 6, and the discharging mechanism is used to drive the two adjacent second clamping plates 23 away from each other when the left installation box 6 is removed from the top of the centrifuge body 1, and a second conveyor 24 is arranged on the left side of the left installation box 6, and a plurality of glass slide racks 25 are fixedly installed on the conveyor belt surface of the second conveyor 24, and a placing mechanism is arranged at the rear end of the left installation box 6, and the placing mechanism is used to place the glass slide in the slide making clamp 2 in the glass slide rack 25 when the left installation box 6 can no longer move to the left;

[0038] During operation, the left side mounting box 6 moves downward and extends into the inner side of the centrifuge body 1. The left side mounting box 6 moves downward and drives the second clamping plate 23 to move downward. During the downward movement of the second clamping plate 23, it is squeezed by the top end of the slide clamp 2, so that the two adjacent second clamping plates 23 move away from each other, thereby clamping the top end of the slide clamp 2. At this time, the placing mechanism clamps the glass slide inside the slide clamp 2. When the left side mounting box 6 moves to the initial position and moves downward, the discharging mechanism drives the two adjacent second clamping plates 23 to move away from each other. At this time, the slide clamp 2 at the bottom end of the left side mounting box 6 falls freely, and then the left side mounting box 6 continues to move to the left. At this time, the placing mechanism starts to align the two glass slides and place them in the glass slide rack 25, thereby realizing the removal and storage of the glass slides.

[0039] As a further solution of the present invention, the discharging mechanism includes a transmission rod 26 arranged at the lower side of the front end of the left mounting box 6, two second limit rods 27 are fixedly installed on the top of the transmission rod 26, two second mounting rings 28 are fixedly installed on the front end of the left mounting box 6, the top ends of the second limit rods 27 pass through the second mounting rings 28 and are slidably connected thereto, the front ends of the second clamping plates 23 are fixedly installed with second push plates 29, the top ends of the transmission rod 26 are fixedly installed with two second trapezoidal plates 30, and the second trapezoidal plates 30 correspond to the bottom ends of the two adjacent second push plates 29, and the left end of the centrifuge body 1 is provided with a material box 31, and the top end of the material box 31 is fixedly installed with an extrusion rod 32, and the rear side of the top end of the extrusion rod 32 corresponds to the transmission rod 26;

[0040] During operation, when the left installation box 6 moves to the initial position and moves downward, the squeezing rod 32 blocks the transmission rod 26. The transmission rod 26 is blocked and drives the two second trapezoidal plates 30 to move upward compared to the installation box 6. At this time, the two adjacent second push plates 29 are squeezed away from each other by the inclined surfaces of the second trapezoidal plates 30, so that the film-making clamp 2 falls freely into the material box 31 for storage under the action of gravity, thereby realizing the storage operation of the discarded film-making clamp 2 and preparing for the subsequent cleaning and secondary use of the film-making clamp 2.

[0041] As a further solution of the present invention, the placement mechanism includes two third clamping plates 33 that are slidably connected to the inner side of the bottom end of the second clamping box 22, two mounting plates 34 are fixedly installed on the bottom end of the second clamping box 22, and a sliding rod 35 is fixedly installed on the ends of the two adjacent third clamping plates 33 that are away from each other. The ends of the sliding rod 35 pass through the mounting plate 34 and are slidably connected thereto. The third clamping plates 33 are connected to the adjacent mounting plates 34 through compression springs, and a push rod 36 is fixedly installed on the rear end of the sliding rod 35. A connecting rod 37 is arranged on the lower side of the rear end of the left mounting box 6, and a third A limiting rod 38, a third mounting ring 39 is fixedly installed at the rear end of the left mounting box 6, the top of the third limiting rod 38 passes through the third mounting ring 39 and is slidably connected thereto, two third trapezoidal plates 40 are fixedly installed at the top of the connecting rod 37, the third trapezoidal plate 40 on the right side corresponds to the bottom ends of the two adjacent push rods 36, a top rod 41 is fixedly installed at the top of the right end of the second conveyor 24, a second limiting plate 42 is fixedly installed at the left end of the second conveyor 24, a second L-shaped rod 43 is slidably connected to the middle of the second limiting plate 42, and the bottom end of the second L-shaped rod 43 is connected to the second limiting plate 42 through a tension spring;

[0042] During operation, the left installation box 6 and thus the top of the material box 31 continue to move to the left. During the process of the left installation box 6 moving to the left, the second clamping box 22 is driven to move synchronously. During the movement, the left second clamping box 22 is blocked by the second L-shaped rod 43, so that the left second clamping box 22 and the second sliding block 21 move to the right compared with the installation box 6. When the installation box 6 can no longer move, the driving mechanism drives the installation box 6 to move downward synchronously. During the downward movement of the left installation box 6, the connecting rod 37 on the lower side is blocked by the top rod 41, so that the connecting rod 37 and the third trapezoidal plate 40 move upward compared with the installation box 6. At the same time, the rear ends of the two adjacent push rods 36 are blocked by the inclined surface of the third trapezoidal plate 40 and move away from each other. The two adjacent push rods 36 move away from each other and drive the two adjacent third clamping plates 33 to move away from each other through the sliding rod 35, so that the glass slide is loosened during the process of being inserted into the inner side of the glass slide rack 25, thereby realizing the placement and induction of the glass slide. The placed glass slide enters the next operation step for processing and inspection under the transportation of the second conveyor 24, so that the inspection operation is more continuous.

[0044] During operation, the electric slide rail 44 starts to drive the support column 45 to move horizontally left and right. During the movement of the support column 45, the U-shaped frame 5 is driven to move left and right, thereby providing power for the left and right movement of the U-shaped frame 5 and the installation box 6; the electric telescopic rod 46 starts to drive the U-shaped frame 5 to move up and down, thereby providing power for the taking and placing of the film clip 2.
