Description

Technical Field

[0001] This invention relates to the field of automated reagent testing technology, specifically to an automated testing device for clenbuterol in pork strips. Background Technology

[0002] Lean meat powder is a type of veterinary drug. Adding lean meat powder to feed can increase the amount of lean meat in animals, reduce feed consumption, bring meat products to market earlier, and reduce costs. However, considering the potential side effects on humans, the standards for its use vary from country to country.

[0003] Detecting the clenbuterol content in pork carcasses typically involves reacting urine with a specialized reagent strip. The reaction result displayed on the strip indicates whether clenbuterol was used in the carcass or if the amount exceeded the permitted limit. Currently, clenbuterol detection in pork carcasses relies heavily on manual labor. The production environment is harsh, and there is a high turnover of personnel. Depending on the production schedule, typically three people are needed to operate the system, resulting in significant labor intensity. Personnel visually assess the reagent strip's reaction results before entering them into the system, leading to issues such as data entry errors, delayed data entry, and low efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an automated detection device for clenbuterol in pork carcasses, which can reduce the intensity of detection work and improve the efficiency and accuracy of detection result collection.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: an automated detection device for clenbuterol in pork carcasses, comprising a synchronous conveying device, an automatic reaction cup feeding device, an automatic reagent strip feeding device, and a result acquisition and judgment device. The synchronous conveying device is equipped with positioning fixtures, which are driven by the synchronous conveying device to sequentially pass through a reaction cup loading station, a reagent strip loading station, a reaction liquid loading station, a visual acquisition station, and an unloading station. The automatic reaction cup feeding device is located at the reaction cup loading station, and the reaction cups are automatically fed when the positioning fixtures are at the reaction cup loading station. The system involves placing reaction cups onto a positioning fixture, with an automatic reagent strip feeding device positioned at the reagent strip feeding station. While the fixture is at this station, the device places reagent strips into the reaction cups. When the fixture is at the reaction liquid feeding station, reaction liquid is added to the reaction cups containing the reagent strips. A result acquisition and judgment device is positioned at the vision acquisition station. While the fixture is at this station, the device collects the information displayed on the reagent strips and determines the reaction results. When the fixture is at the unloading station, the reaction cups and reagent strips detach from the fixture. This automated process, utilizing detection equipment, enables the placement of reaction cups into the fixture, the loading of reagent strips into the reaction cups, and the automatic acquisition of reaction results after adding reaction liquid, thus reducing manpower on the production line and lowering labor intensity.

[0006] As an optional technical solution, the automatic reaction cup feeding device includes a reaction cup direct vibration feeding component, a baffle component, and a discharge guide component. The reaction cup direct vibration feeding component is provided with a discharge hole. The baffle component is located at the feeding end of the reaction cup direct vibration feeding component and moves between a discharge blocking position and a discharge clearance position along the direction in which the reaction cup is conveyed. The discharge guide component is provided with a discharge hole and is located below the reaction cup direct vibration feeding component, moving between a discharge position and a discharge blocking position. When the discharge guide component is at the discharge position, the discharge hole and the discharge hole are connected to form a discharge channel. When the positioning fixture is at the reaction cup loading station, the reaction cup on the positioning fixture is placed below the discharge channel.

[0007] As an optional technical solution, the reaction cup direct vibration feeding component includes a movable guide groove and a first direct vibration driver for driving the movable guide groove to directly vibrate and feed material. The discharge hole is set on the movable support end face of the movable guide groove. The distance between the lower end face of the baffle and the movable support end face of the movable guide groove is not greater than the height of the reaction cup, and the distance between the lower end face of the baffle and the upper end face of the discharge guide is greater than the height of the reaction cup.

[0008] As an optional technical solution, the automatic feeding device for reaction cups also includes a mounting base plate, on which a material blocking drive and a material dropping drive are provided. The actuating part of the material blocking drive is connected to the material blocking component and drives the material blocking component to move along the moving guide groove between the material discharge blocking position and the material discharge clearance position. The actuating part of the material dropping drive is connected to the material dropping guide and drives the material dropping guide to move between the material dropping position and the material dropping blocking position.

[0009] As an optional technical solution, the automatic reagent strip feeding device includes a reagent strip feeding mechanism and a reagent strip direct vibration feeding component. The reagent strip feeding mechanism includes a feeding guide trough, a waiting guide trough, a waiting stop, and a pushing component. The discharge part of the reagent strip direct vibration feeding component is connected to the waiting guide trough, and the reagent strip direct vibration feeding component feeds the reagent strip into the waiting guide trough. The feeding guide trough is located above the synchronous conveying device and is connected to the discharge end of the waiting guide trough. The waiting stop is located at the junction of the feeding guide trough and the waiting guide trough and moves between the feeding blocking position and the feeding clearance position. The pushing component is located above the waiting guide trough and moves along the waiting guide trough between the pushing feeding position and the pushing standby position. When the waiting stop is in the feeding clearance position, it pushes the reagent strip in the waiting guide trough into the feeding guide trough. When the positioning fixture is at the reagent strip loading station, the reaction cup on the positioning fixture is placed at the discharge end of the feeding guide trough.

[0010] As an optional technical solution, the reagent strip direct vibration feeding component includes a vibrating feeding plate, a pressure rod, and a second direct vibration driver. The pressure rod is set on the feeding end face of the vibrating feeding plate, and a gap is reserved between the pressure rod and the feeding end face to form a feeding channel. A support end face is provided on the feeding end face of the vibrating feeding plate along the feeding channel. The vibration part of the second direct vibration driver is connected to the vibrating feeding plate and drives the vibrating feeding plate to vibrate.

[0011] As an optional technical solution, the automatic reagent strip feeding device also includes a reagent strip circular vibrating feeder, the discharge section of which is connected to the feeding channel and the reagent strip circular vibrating feeder provides reagent strips with a specific orientation to the feeding channel; the automatic reaction cup feeding device also includes a reaction cup circular vibrating feeder, the discharge section of which is connected to the moving guide trough and feeds the reaction cup to the moving guide trough.

[0012] As an optional technical solution, the result acquisition and judgment device includes a visual imaging mechanism and a judgment system. The visual imaging mechanism is set above the synchronous transport device. The visual imaging mechanism captures the actual results of the chemical reaction between the reagent strip and the reaction liquid at the visual acquisition station and uploads them to the judgment system. The judgment system compares and analyzes the captured results and judges the reaction results of the reagent strip.

[0013] As an optional technical solution, the positioning fixture is equipped with a reaction cup placement slot, and the synchronous transport device is equipped with two alignment frames between the reaction liquid loading station and the vision acquisition station. The alignment frames are equipped with alignment guide rods, which are set along the transport direction of the synchronous transport device. The gap between the two alignment guide rods forms a reagent strip moving channel.

[0014] As an optional technical solution, the synchronous conveying device is a belt conveyor. The unloading station is set at the end of the synchronous conveying device. A receiving container is set below the synchronous conveying device at the unloading station. The synchronous conveying device drives the positioning fixture to flip at the end of the conveying and pours the reaction cup and reagent strip into the receiving container.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The testing equipment of the present invention can save manpower on the production line and reduce the labor intensity of personnel. The synchronous conveying device drives the positioning fixture to move. With the cooperation of the automatic reaction cup feeding device and the automatic reagent strip feeding device, the reaction cup and fixture are automatically fed. In addition to adding reaction liquid to the reaction cup, personnel also need to replenish the automatic reaction cup feeding device and the automatic reagent strip feeding device regularly, which effectively reduces the labor intensity. 2. The detection equipment of the present invention can improve the accuracy of the detection results. The synchronous transport device drives the positioning fixture to move. After the personnel add the reaction liquid to the reaction cup, when the positioning fixture is driven to the vision acquisition station, the result acquisition and judgment device takes a picture of the reagent strip. The system compares the results with high precision to determine the information displayed by the reagent strip. In addition to replacing the personnel to make high-precision judgments, the result acquisition and judgment device can also directly input the information, which solves the problems of low input efficiency, incorrect input information, and untimely input information. 3. The automatic reaction cup feeding device has a simple and reasonable structure. The reaction cup feeding mechanism arranges the reaction cups and sends them into the moving guide groove. The feeding mechanism can also drive the reaction cups to move along the moving guide groove without the need for additional walking drive components. After the reaction cups enter the discharge hole, they are supported by the dropping guide. The baffle also separates the reaction cups in the discharge hole from the other reaction cups while blocking the material, so as to prevent the reaction cups in the discharge hole from tilting due to contact and collision with adjacent reaction cups when they are discharged along the dropping channel.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0019] like Figures 1-5As shown, an automated detection device for clenbuterol in pork strips can automatically place a reaction cup into the positioning fixture 11, automatically place a reagent strip into the reaction cup, and after the reaction liquid is manually added to the reaction cup, the detection device in this embodiment can also automatically collect the reaction results displayed by the reagent strip and automatically evaluate the detection results based on the reaction results displayed by the reagent strip. Compared with the existing manual operation method, it can not only effectively reduce the labor intensity of personnel, but also improve the detection efficiency and the accuracy of the detection results.

[0020] The detection equipment in this embodiment is mainly used for the automated detection of clenbuterol in carcasses. The reaction solution is the body fluid or urine of the carcasses. After the reagent strip comes into contact with the body fluid or urine of the carcasses in the reaction cup, it will produce a specific result. Based on the result, it is determined whether the carcasses have been treated with clenbuterol or whether the clenbuterol content exceeds the limit.

[0021] The testing equipment in this embodiment includes a synchronous transport device 1, an automatic reaction cup feeding device 2, an automatic reagent strip feeding device 3, and a result acquisition and judgment device 4. The synchronous transport device 1 is equipped with a positioning fixture 11, which has a reaction cup placement position for positioning the reaction cups, allowing for precise control of the reaction cups' movement via the synchronous transport device 1. The synchronous transport device 1 can move each positioning fixture 11, enabling the positioning fixture 11 and the reaction cups placed on it to sequentially pass through a reaction cup loading station, a reagent strip loading station, a reaction liquid loading station, a visual acquisition station, and an unloading station. The reaction cup loading station is equipped with the automatic reaction cup feeding device 2, the reagent strip loading station with the automatic reagent strip feeding device 3, and the visual acquisition station with the result acquisition and judgment device 4.

[0022] When the synchronous transport device 1 moves the positioning fixture 11 to the reaction cup loading station, the automatic reaction cup feeding device 2 places an empty reaction cup at the reaction cup placement position of the positioning fixture 11. When the synchronous transport device 1 then moves the positioning fixture 11 to the reagent strip loading station, the automatic reagent strip feeding device 3 places a reagent strip into the empty reaction cup on the positioning fixture 11. When the synchronous transport device 1 then moves the positioning fixture 11 to the reaction liquid loading station, reaction liquid in the form of urine, body fluid, etc., can be added to the reaction cup manually or by external equipment. The detection area of ​​the reagent strip comes into contact with the reaction liquid and reacts. When the synchronous transport device 1 moves the positioning fixture 11 to the vision acquisition station, the vision imaging mechanism of the result acquisition and judgment device 4 captures the reagent strip. The reaction result displayed on the reagent strip is compared with the result by a dedicated judgment system to determine the detection result. Then, the transport mechanism moves the positioning fixture 11 to the unloading station, and the reaction cup and reagent strip are detached from the positioning fixture 11 manually or by other operations.

[0023] Please see Figures 1-4The synchronous conveying device 1 is a belt conveyor. Positioning fixtures 11 are installed on the conveying surface of the synchronous conveying device 1. In the conveying direction of the synchronous conveying device 1, the distance between each adjacent station is an integer multiple of the distance between adjacent positioning fixtures 11, so that when a positioning fixture 11 is in place at the reaction cup loading station, at least one positioning fixture 11 is in place at the reagent strip loading station, the reaction liquid loading station, and the visual acquisition station. The unloading station is located at the end of the synchronous conveying device 1. A receiving container 13 is installed below the synchronous conveying device 1 at the unloading station. The receiving container 13 is a box structure with an open top. When the synchronous conveying device 1 moves the positioning fixture 11 to the end of the conveying, the positioning fixture 11 flips from the upper conveying surface of the synchronous conveying device 1 to the lower conveying surface. Under the action of gravity, the reaction cups placed on the positioning fixture 11 and the reagent strips and reaction liquids in the cups detach from the positioning fixture 11 and fall into the receiving container 13.

[0024] As an optional implementation, a layered filter plate can be provided in the receiving container 13 to separate the reaction cup and reagent strip from the receiving container 13.

[0025] The positioning fixture 11 is connected to the conveying surface of the synchronous conveying device 1. The positioning fixture 11 is provided with a reaction cup placement position. The reaction cup placement position can be in the form of a reaction cup placement groove opened on the positioning fixture 11. This not only enables the precise placement of the reaction cup, but also prevents the reaction cup from tipping over due to movement or the placement of reagent strips.

[0026] Please see Figure 1 , Figure 2 The automatic reaction cup feeding device 2 includes a reaction cup circular vibratory feeder 21, a reaction cup loading mechanism, and a mounting base plate. The reaction cup circular vibratory feeder 21 adopts the existing technology of a vibrating feeding plate device for reaction cups. After manual feeding of the reaction cup circular vibratory feeder, the reaction cup circular vibratory feeder can arrange the reaction cups in a specific orientation and provide them one by one to the reaction cup loading mechanism. The reaction cup loading mechanism loads the reaction cups onto the positioning fixture 11 at the reaction cup loading station. The reaction cup loading mechanism includes a reaction cup direct vibration feeder 22, a baffle 23, and a discharge guide 24. The reaction cup direct vibration feeder 22 includes a moving guide trough and a first direct vibration driver. The first direct vibration driver drives the moving guide trough to move and feed the reaction cups along the guide trough by driving it to vibrate directly. The moving guide trough is a straight trough, which can neatly hold a row of reaction cups. The discharge section of the reaction cup circular vibration feeder 21 is connected to the moving guide trough. The reaction cup circular vibration feeder 21 adds the reaction cups one by one into the moving guide trough. Driven by the first direct vibration driver, the reaction cups in the moving guide trough move towards the end. The moving guide trough has a discharge hole on its bottom plate. The shape and size of the discharge hole are larger than the top view outline of the reaction cup, allowing the reaction cup to fall through the discharge hole when it moves to the discharge hole.

[0027] The mounting base is set at the reaction cup loading station. The mounting base is equipped with a baffle drive 25 and a discharge drive 26. The baffle drive 25 and the discharge drive 26 are telescopic drive components in the form of cylinders, or other types of reciprocating linear drive components. The moving part of the baffle drive 25 is connected to the baffle 23. The baffle drive 25 drives the baffle 23 to move along the moving guide groove between the discharge blocking position and the discharge clearance position. When the baffle 23 is in the discharge blocking position, the baffle 23 moves to a position above the discharge hole and prevents the reaction cup in the moving guide groove from continuing to move towards the discharge hole. When the baffle 23 is in the discharge clearance position, the baffle 23 moves towards the end of the moving guide groove and is offset from the location of the discharge hole, so that the reaction cup in the moving guide groove can move to the discharge hole for discharge.

[0028] The material discharge guide 24 is located below the moving guide channel. The actuating part of the material discharge drive 26 is connected to the material discharge guide 24. The material discharge drive 26 drives the material discharge guide 24 to move between the material discharge position and the material discharge blocking position. The material discharge guide 24 is provided with a material discharge hole, which is preferably a hole with the same shape as the discharge hole. When the material discharge guide 24 is in the material discharge position, the material discharge hole corresponds to the discharge hole, and the material discharge hole and the discharge hole form a material discharge channel. The reaction cup in the reaction cup direct vibration feeder 22 can fall along the material discharge channel. When the positioning fixture 11 is in the reaction cup loading position, the reaction cup on the positioning fixture 11 is placed below the material discharge channel, and the reaction cup can fall directly into the designated position on the positioning fixture 11 along the material discharge channel. When the material discharge guide 24 is in the material discharge blocking position, the material discharge guide 24 blocks the discharge port. When the reaction cup in the reaction cup direct vibration feeder 22 falls into the discharge hole, it is supported by the material discharge guide 24.

[0029] In some embodiments, a feed hole is provided on the substrate, the shape and position of which correspond to the discharge hole. When the discharge guide 24 is in the discharge position, the discharge hole, the discharge hole and the discharge hole are in the same position and form a discharge channel. A longer discharge channel can help maintain the state of the reaction cup during the discharge process and avoid changes in the position state.

[0030] The lower end face inside the movable guide groove is its movable support end face. The distance between the lower end face of the baffle 23 and the movable support end face of the movable guide groove is not greater than the height of the reaction cup, so that the baffle 23 can block the movement of the reaction cup inside the direct vibration feeder 22 when it moves along the reaction cup. To improve the stability of the reaction cup feeding and prevent the reaction cup from being affected by adjacent reaction cups when moving along the discharge channel, in a further embodiment, the distance between the lower end face of the baffle 23 and the upper end face of the discharge guide 24 is greater than the height of the reaction cup. When the discharge guide 24 is in the discharge blocking position, the baffle 23 moves from the discharge blocking position to the discharge clearance position. After the reaction cup at the foremost end in the moving guide groove is pushed into the discharge hole and supported by the discharge guide 24, since the distance between the lower end face of the baffle 23 and the upper end face of the discharge guide 24 is greater than the height of the reaction cup, the baffle 23 can move from the discharge clearance position to the discharge blocking position without being affected by the reaction cup at the foremost end, thus blocking the reaction cups behind. After the positioning fixture 11 is in place at the reaction cup loading station, the discharge guide 24 moves from the discharge blocking position to the discharge position, at which time the reaction cup in the discharge hole falls along the discharge channel.

[0031] Please see Figure 1 and Figure 2 In some embodiments, the reaction cups are selected with guide ears. When the reagent strip is inserted into the reaction cup, the guide ears can support the reagent strip. In this case, the reaction cup circular vibratory feeder 21 needs to be a vibratory feeder plate product that can arrange the reaction cups according to their orientation, ensuring that the orientation of each reaction cup supplied to the reaction cup direct vibratory feeder 22 is consistent. Optionally, a cover plate is provided on the moving guide groove, and the cover plate has holes reserved for the guide ears to extend out. When the reaction cup moves in the reaction cup direct vibratory feeder 22, the guide ears of the reaction cup extend out of the moving guide groove.

[0032] Please see Figure 1 , Figure 3 and Figure 4The automatic reagent strip feeding device 3 includes a reagent strip circular vibratory feeder 37, a reagent strip direct vibratory feeder, and a reagent strip feeding mechanism. The reagent strip circular vibratory feeder 37 adopts a vibratory feeding tray device for reagent strips, which can realize directional feeding of reagent strips. As a specific example, the discharge section of the reagent strip circular vibratory feeder 37 is equipped with a discharge guide plate. The reagent strip circular vibratory feeder 37 outputs the reagent strips onto the discharge guide plate in a specific orientation and pushes the reagent strips along the discharge guide plate. The surface of the discharge guide plate gradually tilts, so that the orientation of the reagent strips gradually changes, and finally the reagent strips output at the end of the discharge guide plate are in an orientation suitable for entering the reagent strip direct vibratory feeder. A detection element and a push-out element can also be set at the discharge guide plate. The detection element detects the arrangement orientation of the reagent strips on the discharge guide plate, and the push-out element pushes away the reagent strips arranged in a non-specified orientation on the discharge guide plate according to the detection result of the detection element, and returns the reagent strips to the reagent strip circular vibratory feeder 37.

[0033] The reagent strip direct vibration feeder is equipped with a feeding channel. The discharge part of the reagent strip circular vibration feeder 37 is connected to the feeding channel. The reagent strip circular vibration feeder 37 feeds the reagent strip into the feeding channel in a specified orientation. The reagent strip direct vibration feeder then vibrates and transports the reagent strip to the waiting guide trough 32 of the reagent strip feeding mechanism.

[0034] The reagent strip feeding mechanism includes a feeding guide 31, a waiting guide 32, a waiting stop 33, and a pusher 34. The feeding guide 31 is inclined and positioned above the synchronous conveying device 1. When the reagent strip is in the feeding guide 31, it can slide down along the inclined feeding guide 31. The waiting guide 32 is above the feeding guide 31. The discharge end of the waiting guide 32 is connected to the inlet end of the feeding guide 31 to form a reagent strip feeding channel. A support structure is provided at the reagent strip loading station, and a waiting drive component is provided on the support structure. The waiting drive component is preferably a telescopic drive component. The actuating part of the waiting drive component is connected to the waiting stop 33. The waiting stop 33 is located at the junction of the loading guide 31 and the waiting guide 32, and is driven by the waiting drive component to move between the loading blocking position and the loading clearance position. When the waiting stop 33 is in the loading blocking position, the end of the waiting stop 33 extends to the junction of the loading guide 31 and the waiting guide 32, blocking the reagent strip loading channel and preventing the reagent strip in the waiting guide 32 from moving into the loading guide 31. When the waiting stop 33 is in the loading clearance position, the end of the waiting stop 33 leaves the junction of the loading guide 31 and the waiting guide 32, the reagent strip loading channel is unobstructed, and the reagent strip in the waiting guide 32 can move into the loading guide 31. The support structure is also equipped with a pusher drive, which is preferably a telescopic drive component. The actuating part of the pusher drive is connected to the pusher 34. The pusher drive can drive the pusher 34 to move along the waiting guide 32 between the pusher loading position and the pusher standby position. When the pusher 34 is in the pusher standby position, the reagent strip direct vibration feeder feeds the reagent strip into the waiting guide 32. When the waiting stop 33 is in the loading clearance position, the pusher 34 moves from the pusher standby position to the pusher loading position, which can push the reagent strip in the waiting guide 32 into the loading guide 31. The reagent strip slides down along the inclined loading guide 31 and finally falls into the reaction cup on the positioning fixture 11 at the reagent strip loading station, thus realizing the loading of the reagent strip.

[0035] Please see Figure 3The reagent strip direct vibration feeding device includes a vibrating feeding plate 35, a pressure rod 36, and a second direct vibration driver. The vibrating feeding plate 35 is inclined, and the upper end face of the inclined vibrating feeding plate 35 is the feeding end face. A support end face is provided on the vibrating feeding plate 35 at the lower edge of the feeding end face. The pressure rod 36 is located above the plate surface of the feeding end face. The pressure rod 36 is parallel to the feeding end face and a gap is reserved between the pressure rod 36 and the feeding end face. This gap is the feeding channel. After the reagent strip circular vibrating feeder 37 feeds the vibrating strip into the feeding channel in a specified orientation, the reagent strip is maintained in a specific orientation by the cooperation of the support end face and the feeding end face, and by the cooperation of the pressure rod 36 and the feeding end face. The second direct vibration driver drives the vibrating feeding plate 35 to vibrate at a specific frequency, so that the reagent strip in the feeding channel moves and is conveyed along the feeding channel. The supporting end face and the pressure rod 36 can be inclined toward the side where the material guide groove 32 is located. When the vibrating feeding plate 35 vibrates, it drives the reagent strip to vibrate. The reagent strip moves toward the material guide groove 32 along the inclined direction of the supporting end face and the pressure rod 36.

[0036] The second and first direct vibration drivers can be direct vibration drivers of model LWCL-100 or similar products, which drive the vibrating feed plate 35 and the moving guide chute to vibrate at a specific frequency to achieve the effect of conveying materials.

[0037] Please see Figure 1 and Figure 4 The result acquisition and judgment device 4 adopts an industrial vision system, including a vision imaging mechanism and a judgment system. The vision imaging mechanism uses an industrial camera of existing technology, and the judgment system uses an intelligent comparison system of existing technology. The industrial vision system is preferably the IV3 series product manufactured by KEYENCE, which can be used with a built-in AI intelligent system for convenient production use. This product includes an intelligent camera sensor head of model IV3-G500CA, an air conditioner of model IV3-G120, and supporting computer software of model IV3-H1. When the detection device in this embodiment is used for clenbuterol detection, the acquisition and judgment system using the above-mentioned products can also adopt an intelligent comparison system that can be connected to the Manufacturing Execution System (MES system) to directly upload the detection results to the MES system, so as to realize information integration and complete real-time monitoring and alarm of the production detection process.

[0038] The visual imaging mechanism is positioned above the synchronous transport device 1. When the positioning fixture 11 is at the visual acquisition station, it is in the optimal shooting position of the visual imaging mechanism. The visual imaging mechanism takes a picture of the reagent strip on the positioning fixture 11 and sends the picture data to the judgment system. The judgment system analyzes and compares the picture with its built-in evaluation standard picture to judge the reaction result shown by the reagent strip.

[0039] As a further embodiment, the synchronous transport device 1 has two alignment frames 12 positioned between the reaction liquid loading station and the visual acquisition station. Alignment guide rods are mounted on the alignment frames 12, positioned above the synchronous transport device 1 and along its transport direction. A gap suitable for the reagent strip to pass through is formed between the two alignment guide rods above the synchronous transport device 1, creating a reagent strip movement channel. When the synchronous transport device 1 moves the positioning fixture 11 past the two alignment frames 12, the reagent strip passes through the reagent strip movement channel, ensuring that the position of the reagent strip carried by the positioning fixture 11 does not shift at the visual acquisition station. This avoids misjudgment due to the result acquisition and judgment device 4 failing to acquire a photograph from a suitable angle because of reagent strip position deviation.

[0040] Please see Figure 1 and Figure 5 In some embodiments, the testing equipment also includes a machine base and a housing 5. A synchronous conveying device 1, an automatic reaction cup feeding device 2, an automatic reagent strip feeding device 3, and a result acquisition and judgment device 4 are all mounted on the machine base. A receiving container 13 is located below the machine base. A discharge port is provided at the discharge station on the machine base to facilitate the placement of tested reaction cups, reagent strips, etc., into the receiving container 13. The housing 5 is attached to the machine base. The synchronous conveying device 1, the automatic reaction cup feeding device 2, the automatic reagent strip feeding device 3, and the result acquisition and judgment device 4 are all located inside the housing 5. An operating port and an operating table are provided at the reaction liquid loading station on the housing 5 to facilitate the addition of reaction liquid to the reaction cups by personnel through the operating port.

[0041] In some embodiments, the result acquisition and judgment device 4 is also equipped with a display screen to set up the judgment system and display the judgment structure. The display screen is mounted on the housing 5, which is also equipped with an alarm and other detection elements such as sensors to monitor the safe operation of the testing equipment. The housing 5 is also equipped with multiple valves to facilitate the maintenance of the testing equipment and the replenishment of materials to the automatic reaction cup feeding device 2 and the automatic reagent strip feeding device 3.

[0042] The following describes the usage process of the equipment in this embodiment using the detection of clenbuterol in pork carcasses as an example. Please refer to the documentation again. Figures 1-5First, empty reaction cups are added to the reaction cup circular vibratory feeder 21, and reagent strips are added to the reagent strip circular vibratory feeder 37. The reaction cup circular vibratory feeder 21 vibrates to feed the reaction cups one by one into the reaction cup direct vibratory feeder 22 of the reaction cup loading mechanism, with the reaction cups in the specified orientation. The reaction cup direct vibratory feeder 22 drives the reaction cups to move. After the material stopper 23 moves from the discharge blocking position to the discharge clearance position, the reaction cup at the foremost end of the reaction cup direct vibratory feeder 22 is conveyed forward and falls into the discharge hole. The material is supported by the material guide 24 at the material blocking position. Then the material blocking member 23 moves from the material discharge clearance position to the material discharge blocking position to prevent the reaction cup in the reaction cup direct vibration feeder 22 from moving forward. When the positioning fixture 11 is transported to the reaction cup loading station, the material guide 24 moves from the material discharge blocking position to the material discharge position. The reaction cup in the discharge hole falls along the material discharge channel to the reaction cup placement position on the positioning fixture 11. The synchronous conveying device 1 drives the positioning fixture 11 to move towards the reagent strip loading station. The reagent strip circular vibratory feeder 37 vibrates to feed the reagent strips one by one to the reagent strip direct vibratory feeder in a specified orientation. The reagent strip direct vibratory feeder delivers the reagent strips to the waiting guide trough 32. After the positioning fixture 11 containing the reaction cup moves to the reagent strip loading station, the waiting stop 33 moves from the loading blocking position to the loading clearance position, and the pusher 34 moves from the push waiting position to the push loading position, pushing the reagent strip in the waiting guide trough 32 into the loading guide trough 31. Then the pusher 34 returns to the push waiting position and the waiting stop 33 returns to the loading blocking position. The reagent strip slides out along the inclined loading guide trough 31 and falls into the reaction cup on the positioning fixture 11. Then the synchronous conveying device 1 drives the positioning fixture 11 to move towards the reaction liquid loading station. When the positioning fixture 11 containing the reaction cup and reagent strip moves to the reaction liquid loading station, the urine or body fluid corresponding to the white strip is added to the reaction cup manually or using special equipment. Then, the synchronous transport device 1 moves the positioning fixture 11 to the vision acquisition station. During the transport process, the detection area on the reagent strip reacts with the urine. When the positioning fixture 11 reaches the vision acquisition station, the result acquisition and judgment device 4 takes a picture of the reagent strip and processes the data on the picture. Then, the synchronous transport device 1 moves the positioning fixture 11 to the unloading station. After reaching the unloading station, with the operation of the synchronous transport device 1, the reaction cup, reagent strip and urine in the reaction cup on the positioning fixture 11 are separated from the synchronous transport device 1 and fall into the receiving container 13 below.
