[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Embodiment 1, as Figure 1 and Figure 2 As shown, a folic acid content detection device includes a shell 1, a detection cabinet 2 is fixedly connected to the upper end of the shell 1, a porthole 3 is opened at the front end of the shell 1, a feeding structure 4 is arranged on the bottom wall of the inner surface of the shell 1, four L-shaped conveyor belts 5 are fixedly installed in a rectangular distribution on the inner surface of the shell 1, and two conveyor belts 5 on the same side are relatively distributed in a Y shape, and a continuous detection structure 6 is arranged in the middle of the upper end of the feeding structure 4.

[0035] It should be specially noted that the above-mentioned conveyor belt 5 is a conventional conveying structure, which is vertically installed and driven by a motor. It vertically conveys materials in the form of two clamps. It is a mature equipment. Its specific installation method, driving method and operating principle will not be displayed or elaborated in the present invention.

[0036] Further, in order to realize quantitative feeding, thereby realizing intermittent feeding and discharging, refer to Figure 3 The feeding structure 4 includes a receiving plate 47 fixedly connected to the middle part of the upper end of the shell 1, and a feeding plate 41 is fixedly connected to the outer surface of the receiving plate 47 symmetrically on the left and right. A driving rod 45 is slidably connected to the lower end of the receiving plate 47, and the lower end of the driving rod 45 is fixedly connected to an electric telescopic rod 46 fixedly connected to the bottom wall of the inner cavity of the shell 1 through a connecting plate. A compression spring 43 is fixedly connected to the lower end of the right feed plate 41, and a wedge block 42 is fixedly connected to the lower end of the compression spring 43. The upper end of the wedge block 42 is symmetrically fixedly connected to a blocking column 44 slidably connected to the feed plate 41. The right side of the driving rod 45 is an inclined surface and is tightly attached to the inclined surface part of the wedge block 42; a sensor three 414 is fixedly installed on one side of the upper end of the two feed plates 41 close to the receiving plate 47.

[0037] When the test tube passes through the sensor 3 414, the electric telescopic rod 46 retracts, and the driving rod 45 pushes the right wedge block 42 to rise, thereby making the blocking column 44 protrude from the upper part of the feed plate 41, thereby blocking the folic acid test tube. The compression spring 43 is mainly used to ensure that the wedge block 42 can always be in close contact with the inclined surface of the driving rod 45;

[0038] The test tube that has completed the inspection on the left side is sent out under the action of the conveyor belt 5. When the sensor three 414 on the left side detects that the test tube has passed, the electric telescopic rod 46 extends, and the blocking column 44 drops below the feed plate 41. The test tube on the right side can enter the operating range of the continuous inspection structure 6 under the action of the conveyor belt 5.

[0039] During the operation of this embodiment, folic acid is first fed into the feeding structure 4 by the action of the conveyor belt 5, and quantitative inward feeding is achieved through the cooperation of the sensor three 414 and the electric telescopic rod 46 through the action of the wedge block 42 and the blocking column 44, and thereby the folic acid test tube is evenly fed into the continuous detection structure 6, and the folic acid solution is pretreated and detected by the cooperation of the continuous detection structure 6 and the detection cabinet 2, and continuous and automatic detection is achieved by the action of the continuous detection structure 6, thereby simplifying the detection process and improving the detection efficiency.

[0040] Embodiment 2. Based on Embodiment 1, this embodiment pulls the folic acid test tube fed by the conveyor belt 5 into the clamping assembly 64 installed in the feeding assembly 62 through the action of the feeding and discharging assembly 61, and drives the clamping assembly 64 to tighten and clamp the folic acid test tube through the cooperation of the elliptical groove 623 provided in the fixed disk 621 and the clamping assembly 64, and drives the rotating disk 622 to rotate through the driving action of the detection cabinet 2 on the transmission column 63 and the fixed disk 621, thereby driving the clamping assembly 64 and the folic acid test tube clamped therein to rotate around the transmission column 63, and then sequentially performs the addition, shaking, and sampling of the treatment agent to complete the detection, and realizes continuous and automatic detection through the coordination of multiple stations in the feeding assembly 62, thereby reducing manual participation, improving detection efficiency, and simultaneously improving detection accuracy because manual errors are eliminated.

[0041] Specifically, in order to move the test tube containing the folic acid solution, refer to Figure 4 The continuous detection structure 6 includes an inlet and outlet assembly 61 fixedly connected to the upper end of the material receiving plate 47, a feeding assembly 62 is arranged on the upper end of the inlet and outlet assembly 61, a plurality of clamping assemblies 64 are arranged in an annular distribution on the inner surface of the feeding assembly 62, and a transmission column 63 is fixedly connected to the upper end of the feeding assembly 62.

[0042] The inlet and outlet assembly 61 is used to intermittently pull the folic acid test tubes in the conveyor belt 5 into the feed assembly 62. Furthermore, the feed assembly 62 can be driven to rotate through the transmission column 63 and the bottom plate 21. The feed assembly 62 is used to drive the folic acid test tubes to rotate around the axis of the transmission column 63, thereby driving the folic acid test tubes to move between the various workstations.

[0043] Further, in order to deliver the folic acid test tubes in the conveyor belt 5 into the clamping assembly 64 installed in the feeding assembly 62, refer to Figure 5 The material inlet and outlet assembly 61 includes a U-shaped seat 611 fixedly connected to the upper end of the material receiving plate 47, a sliding plate 612 is slidably connected to the inner surface of the U-shaped seat 611, a relay plate 613 is fixedly connected to the right end of the sliding plate 612, a one-way flap 614 is rotatably connected to the rear end of the relay plate 613, and the upper end of the U-shaped seat 611 is fixedly connected to the material feeding assembly 62;

[0044] See also Figure 6 The U-shaped seat 611 also includes a bracket 615 fixedly connected to the bottom wall of the inner surface of the U-shaped seat 611, a motor 616 is fixedly installed at one end of the bracket 615, and a gear set 617 is fixedly connected to the output end of the motor 616. An eccentric disk 618 is rotatably connected to the inner surface of the bracket 615, and a tooth groove meshing with the gear set 617 is opened in the middle of the outer surface of the eccentric disk 618. The front and rear ends of the eccentric disk 618 are eccentrically fixedly connected to the connecting column 610, and the inner surface of the sliding plate 612 is symmetrically opened with straight grooves 619 slidingly connected to adjacent connecting columns 610.

[0045] The motor 1 616 drives the eccentric disk 618 to rotate through the gear set 617, thereby driving the straight groove 619 to move in a circular trajectory through the eccentric disk 618. Further, the cooperation between the eccentric disk 618 and the straight groove 619 drives the straight groove 619 to slide left and right in the U-shaped seat 611.

[0046] When the sliding plate 612 slides to the left, the test tube at the left station will be pushed into the conveyor belt 5 by the sliding plate 612. When the sliding plate 612 slides to the right, the one-way flap 614 is forced to flip to the left. The one-way flap 614 is one-way and can only flip to the left. Further, the sliding plate 612 moves to the left, and the one-way flap 614 will push the test tube into the inside of the feeding assembly 62. When the feeding assembly 62 rotates, the test tube will be brought to the next station through the clamping assembly 64.

[0047] Further, in order to clamp and fix the folic acid test tube, refer to Figure 7 and Figure 8 The clamping assembly 64 includes a fixed rod 641 fixedly connected to the inner surface of the rotating disk 622, a slider 646 is slidably connected to the inner surface of the fixed rod 641, and the left and right ends of the slider 646 are symmetrically rotatably connected to the connecting rods 645, and the ends of the two connecting rods 645 away from the slider 646 are both rotatably connected to the clamping arms 644, and the ends of the two clamping arms 644 close to each other are rotatably connected to the fixed seat 642 fixedly connected to the side of the fixed rod 641 away from the fixed disk 621, the side of the slider 646 away from the fixed seat 642 is fixedly connected to the spring pull rod 647, and the side of the spring pull rod 647 away from the slider 646 is fixedly connected to the pulley 648 slidably connected to the inner surface of the elliptical groove 623.

[0048] Further, in order to accommodate the clamping assembly 64 and drive it to contract to clamp the folic acid test tube, refer to Figure 7 The feeding assembly 62 includes a fixed plate 621 fixedly connected to the upper end of the U-shaped seat 611, an inner surface of the fixed plate 621 is provided with an elliptical groove 623 slidably connected to a plurality of clamping assemblies 64, an outer surface of the fixed plate 621 is rotatably connected to a rotating plate 622, an outer surface of the rotating plate 622 is fixedly connected to the clamping assembly 64 via an arc-shaped groove, and an upper end of the rotating plate 622 is fixedly connected to the transmission column 63.

[0049] In summary, when the fixed disk 621 rotates around the rotating disk 622, the pulley 648 will slide in the elliptical groove 623. Since the path of the elliptical groove 623 is an elliptical path, when the pulley 648 is at the long radius of the elliptical groove 623, the slider 646 is pulled by the spring pull rod 647 to the side away from the fixed seat 642. At this time, the connecting rod 645 will pull the clamping arm 644 to rotate around the connecting rod 645, and the clamping arm 644 will open; when the slider 646 is at the short radius of the elliptical groove 623, the slider 646 is pushed by the spring pull rod 647 to the side close to the fixed seat 642. At this time, the connecting rod 645 drives the clamping arm 644 to rotate to the side away from the fixed seat 642. The clamping arm 644 clamps the test tube and drives the test tube to the next workstation following the rotation of the rotating disk 622.

[0050] Embodiment 3. Based on Embodiment 2, this embodiment further controls the feeder 23 and the active agent delivery needle 24 to deliver the buffer solution and the ammonia solution to the folic acid test tube through the action of the sensor 1 412. Furthermore, the folic acid test tube filled with the treatment agent is shaken by the micro-oscillator 411 to make it fully mixed, and the liquid pump 25 is used to drive the liquid collection needle 262 to extend and extract the mixed solution in the test tube, thereby sending it into the material mixing plate 28 through the sampling tube 267, and detecting it through the spectrum detector 27. After the detection is completed, the cleaning box 29 is used for backwashing, and the folic acid solution remaining on the inner wall of the spectrum detector 27, the sampling tube 267, and the liquid collection needle 262 is cleaned by saline, and the waste water is sent to the waste water tank 266 through the cleaning sponge 264 to prevent the residual solution in the subsequent detection process from affecting the detection accuracy.

[0051] Specifically, to achieve the processing and detection of folic acid content in folic acid solution, refer to Fig. 9 A bottom plate 21 is fixedly connected to the top wall of the inner cavity of the shell 1, a motor 22 which is transmission-connected to the transmission column 63 is fixedly connected to the middle part of the upper end of the bottom plate 21, a spectrum detector 27 is fixedly connected to the left part of the upper end of the bottom plate 21, a material leveling plate 28 is fixedly connected to the rear end of the spectrum detector 27, a cleaning box 29 is fixedly connected to the front part of the upper end of the bottom plate 21, the material leveling plate 28 and the cleaning box 29 are connected through two one-way pipes, a feeder 23 is fixedly connected to the right part of the upper end of the bottom plate 21, and an active agent delivery needle 24 which passes through the upper end of the bottom plate 21 and extends to the inner cavity of the shell 1 is fixedly connected to the right end of the feeder 23 through a water pipe, and a sampling component 26 is jointly provided at the rear part of the upper end of the bottom plate 21 and the rear part of the inner cavity of the shell 1.

[0052] A barcode scanner is also provided at the lower part of the bottom plate 21 for scanning the traceability QR code on the surface of the test tube, so as to facilitate tracing the specific source of the detection reagent and confirm the unqualified product batch.

[0053] Among them, the active agent delivery needle 24 is a conventional feeding device, which is filled with a buffer solution and an ammonia solution to maintain the pH value of the solution stable and dissolve folic acid to facilitate subsequent testing;

[0054] The spectrum detector 27 and the screed plate 28 are mature detection devices in the prior art. The screed plate 28 spreads the solution extracted by the sampling component 26 and performs spectrum detection on it through the spectrum detector 27. After the detection is completed, the cleaning box 29 is used to backwash and clean the screed plate 28 to avoid the residual solution in the subsequent detection process affecting the detection accuracy.

[0055] At the same time, the cleaning box 29 is divided into two chambers, which are used to store saline for cleaning and folic acid solution after testing, and are transported by pumps respectively. The two pumps installed in the cleaning box 29 can drive the sampling assembly 26 to extract the solution in the folic acid test tube or perform backwashing;

[0056] The above structure has been widely used in the prior art. In the present invention, it is only used to realize the function, and its internal structure, operating principle, wiring, and control method are not described in detail.

[0057] Further, to achieve sampling of folic acid solution, refer to Fig.10 and Fig.11 The sampling component 26 includes a fixed cylinder 261 that passes through the upper end of the bottom plate 21 and extends to the inner cavity of the shell 1. A liquid collection needle 262 is slidably connected to the inner surface of the fixed cylinder 261. A cleaning sponge 264 wrapped around the outer surface of the liquid collection needle 262 is fixedly connected to the rear part of the inner cavity of the shell 1. A hydraulic cavity 263 is opened at the rear part of the inner cavity of the shell 1. A water receiving trough 265 is slidably connected to the inner surface of the hydraulic cavity 263. A waste water tank 266 connected to the water receiving trough 265 through a drain pipe is fixedly connected to the rear end of the shell 1. The inner cavities of the fixed cylinder 261 and the hydraulic cavity 263 are filled with hydraulic oil and are commonly connected to a liquid pump 25 fixedly connected to the upper end of the bottom plate 21. A sampling tube 267 connected to the material leveling plate 28 is fixedly connected to the upper end of the liquid collection needle 262.

[0058] The liquid pump 25 transports the hydraulic oil in the hydraulic chamber 263 to the fixed cylinder 261, and thereby pushes the liquid collection needle 262 to move downward. At the same time, since the volume of the hydraulic oil in the hydraulic chamber 263 is reduced, the water receiving tank 265 moves backward and does not block the descending path of the liquid collection needle 262. Then, the solution in the folic acid test tube can be extracted through the liquid collection needle 262, and then sent to the material leveling plate 28 through the sampling tube 267 for detection. After the detection is completed, the cleaning box 29 draws the detected solution into the cleaning box 29 through the connecting tube, and after the liquid collection needle 262 is reset, saline is transported into the material leveling plate 28 for impact, thereby washing away the residual components in the material leveling plate 28, the sampling tube 267, and the liquid collection needle 262.

[0059] After the liquid collection needle 262 is reset, the hydraulic oil in the hydraulic chamber 263 and the fixed cylinder 261 returns to the initial volume, and the water receiving tank 265 is located below the liquid collection needle 262. The flushing waste water will enter the water receiving tank 265 through the liquid collection needle 262, and finally be discharged into the waste water tank 266 through the waste water pipe for temporary storage.

[0060] Further, to confirm the position of the folic acid test tube, refer to Fig.11 A sensor 1 412 is fixedly installed at the position below the active agent delivery needle 24 on the upper end of the material receiving plate 47, a sensor 2 413 is fixedly installed at the position below the sampling component 26 on the upper end of the material receiving plate 47, and a micro-oscillator 411 is fixedly installed at the position in the middle of the arc path between the sensor 2 413 and the sensor 1 412 on the upper end of the material receiving plate 47.
