Description

Technical Field

[0001] This utility model relates to the field of testing card supply technology, specifically to a testing card supply mechanism. Background Technology

[0002] Food safety emphasizes that food should not contain substances or factors that may harm or threaten human health. Therefore, food safety testing is particularly important. Currently, food testing instruments commonly used in the market typically have separate food sample extraction and testing device sets. The sampling device collects food samples and then transfers them to reagent cards or test cards. Existing instruments require manual placement of each reagent card or test card into the reaction dish, which is labor-intensive and inefficient. To reduce manual labor, reagent cards or test cards can be automatically picked up and placed into the reaction dish using grippers. However, existing test card feeding mechanisms use a screw to raise a lifting plate in the feeding compartment, which in turn raises the test cards on the lifting plate to the top for gripper pickup. But with this method, the lifting plate can easily jam against the inner wall of the feeding compartment if it deforms after prolonged use or if there are errors in the lifting height at both ends, resulting in an uneven tilt. This makes it difficult for the equipment to remove the cards. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a card supply mechanism for a detection card. By using telescopic adjustment components and sliding components on both sides of the support platform, the mechanism can support the support platform and absorb the displacement difference when there is a height difference between the two ends of the support platform. The sliding components slide with the card supply compartment to avoid the two ends of the support platform from being rigidly jammed with the inner wall of the card supply compartment, thus ensuring the normal operation of the equipment.

[0004] This utility model provides a card feeding mechanism for a detection card to solve the above-mentioned technical problems. It includes a worktable with a card feeding compartment open at both the top and bottom. The card feeding compartment has jaw clearance openings on its long side walls. A support platform is movably mounted inside the card feeding compartment. Telescopic adjustment members are provided at both axial ends of the support platform, and a sliding member is provided at the other end of each telescopic adjustment member. Vertical limiting grooves with a larger bottom and smaller opening are provided on the short side walls of the card feeding compartment. The sliding member is slidably engaged within the vertical limiting grooves. The worktable has mounting holes corresponding to the card feeding compartment. A lifting cylinder is vertically slidably engaged within the mounting holes. A top plate that can act on the bottom of the support platform is fixed to the top of the lifting cylinder. The lifting cylinder is driven to rise and fall by a lifting drive mechanism.

[0005] Furthermore, the telescopic adjustment member includes a guide cylinder fixed to the support platform and a guide post fixed to the sliding member, the guide cylinder being movably sleeved on the guide post and an elastic member being provided between the guide post and the guide cylinder.

[0006] Furthermore, a vertical guide groove is provided on the side wall away from the telescopic adjustment member of the vertical limiting groove, and the sliding member includes a guide wheel that is rolled in the vertical guide groove, and the rotation axis of the guide wheel is perpendicular to the axis of the telescopic adjustment member.

[0007] Furthermore, the lifting drive mechanism includes a rotary motor, the output end of which is fixed with a screw. The screw is rotatably positioned below the worktable via a support frame, and the lifting cylinder is threadedly engaged with the screw.

[0008] Furthermore, the top plate is also provided with a guide rod, the lower end of which moves through a guide hole on the worktable, and the lower end of the guide rod is provided with a limiting plate.

[0009] Furthermore, the inner peripheral wall of the mounting hole is provided with a guide notch, and the outer peripheral wall of the lifting cylinder is provided with a guide protrusion that slides in cooperation with the guide notch.

[0010] Furthermore, a mounting groove is provided on the top of the inner side wall of one short side of the card supply compartment, and a photoelectric sensor is provided in the mounting groove.

[0011] The beneficial effects of this utility model are as follows: The workbench supports the card supply compartment. Both the upper and lower ends of the card supply compartment are open. The lower opening allows the top plate to act on the support platform through the lower opening of the card supply compartment, causing it to rise. The upper opening facilitates the removal or insertion of the test card from the card supply compartment. The jaw clearance openings on the long side walls of the card supply compartment allow the jaws to move freely, ensuring they can grip both sides of the test card. A movable support platform is installed inside the card supply compartment to support the test card. When the test card is inserted into the card supply compartment, it is positioned above the support platform. Telescopic adjustment components are provided at both axial ends of the support platform. These components absorb height differences generated during the lifting and lowering of the support platform, preventing the two ends of the support platform from becoming rigidly jammed with the card supply compartment. Vertical limiting grooves on the short side walls of the card supply compartment accommodate and guide sliding components, ensuring smooth lifting and lowering of both ends of the support platform, reducing the possibility of height differences between the two ends of the support platform, and further ensuring the normal operation of the equipment. The workbench is equipped with mounting holes corresponding to the card supply compartment. The lifting cylinder in the mounting hole is raised and lowered by a lifting drive mechanism, which in turn drives the top plate at the top of the lifting cylinder to rise and fall. The top plate can push the support platform to rise, or when the top plate falls, the support platform falls by its own weight.

[0012] In summary, by employing this utility model, during the rising or falling process of the support platform, the sliding component and the inner wall of the vertical limiting groove slide together, ensuring stable movement at both ends of the support platform, reducing the possibility of height differences at both ends of the support platform, and even if height differences occur at both ends, the extension and retraction of the telescopic adjustment component can absorb the height displacement difference, so that the two ends of the support platform will not make rigid contact with the inner wall of the card supply compartment, thereby preventing hard jamming and ensuring the normal operation of the equipment.

Detailed Implementation

[0017] Referring to the accompanying drawings, the specific embodiments of this utility model will be described in detail.

[0018] Reference Figures 1 to 2 This utility model provides a card feeding mechanism for a detection card, including a workbench 1 for supporting a card feeding compartment 2. The workbench 1 has a card feeding compartment 2 with openings at both the top and bottom. The lower opening allows a top plate 7 to act on the support platform 3 through the lower opening of the card feeding compartment 2, causing it to rise. The upper opening facilitates the removal or insertion of detection cards from or into the card feeding compartment 2. To ensure accurate installation of the card feeding compartment 2, a positioning post can be provided on the workbench 1, and the card feeding compartment 2 has a positioning groove corresponding to the positioning post.

[0019] The card supply compartment 2 has jaw clearance openings 21 on both long side walls for the jaws to allow them to grip the sides of the detection card. A support platform 3 is movably mounted inside the card supply compartment 2. The support platform 3 is a plate-like structure; when a detection card is inserted into the card supply compartment 2, the card is positioned on top of the support platform 3. Furthermore, a mounting groove 24 is provided at the top of the inner side wall of one short side of the card supply compartment 2. A photoelectric sensor 25 is installed in the mounting groove 24. The photoelectric sensor 25 can detect whether a detection card is present at the card retrieval position. If no detection card is detected at the card retrieval position, the control program controls the top plate 7 to rise, pushing the support platform 3 upwards, and further pushing the detection card upwards until it is positioned at the card retrieval position. When the photoelectric sensor 25 detects the detection card, the control program controls the top plate 7 to stop moving.

[0020] The support platform 3 is equipped with telescopic adjustment components 4 at both axial ends to absorb the height difference generated during the lifting and lowering of the support platform 3, and to prevent the two ends of the support platform 3 from being rigidly jammed with the card supply compartment 2. Two sets of telescopic components can be symmetrically arranged along the support platform 3 to further ensure the stable lifting and lowering of the support platform 3 and to provide stable support for the support platform 3.

[0021] Furthermore, the telescopic adjustment component 4 includes a guide cylinder 41 fixed to the support platform 3 and a guide post 42 fixed to the sliding component 5. The guide cylinder 41 is movably sleeved on the guide post 42, and an elastic element 43 is provided between the guide post 42 and the guide cylinder 41. In this case, when a height difference occurs on both sides of the support platform 3, the guide post 42 slides within the guide cylinder 41, changing the common length of the guide cylinder 41 and the guide post 42 to compensate for the offset. The elastic element 43 ensures that the lengths of the guide cylinder 41 and the guide post 42 can adapt adaptively, thereby achieving adaptive height difference compensation. It also buffers external impacts, reducing the possibility of deformation of the support platform 3 and further reducing the possibility of the support platform 3 jamming.

[0022] The other end of the telescopic adjustment member 4 is provided with a sliding member 5. In this embodiment, the sliding member 5 is fixed to the guide post 42. Vertical limiting grooves 22 with a larger bottom and smaller opening are provided on the short side walls of the card supply compartment 2. The sliding member 5 is slidably fitted within the vertical limiting grooves 22. The vertical limiting grooves 22 are used to accommodate and guide the sliding member 5, ensuring the smooth lifting and lowering of both ends of the support platform 3, reducing the possibility of inconsistent movement at both ends of the support platform 3, and further reducing the possibility of the support platform 3 jamming. Furthermore, a vertical guide groove 23 is provided on the side wall of the vertical limiting groove 22 away from the telescopic adjustment member 4. The sliding member 5 includes a guide wheel 51 that rolls within the vertical guide groove 23. Preferably, part of the guide wheel 51 is located within the vertical guide groove 23, guiding the guide wheel 51 through the vertical guide groove 23, reducing the possibility of the guide wheel 51 shifting, and further ensuring the stable lifting and lowering of the support platform 3. The rotation axis of the guide wheel 51 is perpendicular to the axis of the telescopic adjustment member 4. At this time, even if there is a height difference between the two ends of the support platform 3, the wheel surface of the guide wheel 51 will always be in vertical contact with the vertical guide groove 23 without any deviation. The guide wheel 51 can still roll in the vertical guide groove 23, so that the support platform 3 will not be hard stuck.

[0023] The workbench 1 is provided with a mounting hole 11 corresponding to the card supply compartment 2. A lifting cylinder 6 is vertically slidably fitted into the mounting hole 11. The mounting hole 11 is a non-circular hole, which can prevent the lifting cylinder 6 from rotating. Furthermore, a guide notch 111 is provided on the inner peripheral wall of the mounting hole 11, and a guide protrusion 61 is provided on the outer peripheral wall of the lifting cylinder 6, which slidably engages with the guide notch 111. Through the cooperation of the guide notch 111 and the guide protrusion 61, the lifting of the lifting cylinder 6 can be guided, ensuring the stable lifting of the lifting cylinder 6, and preventing the lifting cylinder 6 from rotating.

[0024] The top of the lifting cylinder 6 is fixed with a top plate 7 that can act on the bottom of the support platform 3. The top plate 7 is used to lift the support platform 3, causing it to rise, or to remove support from the support platform 3, causing it to fall under its own weight. Preferably, the top of the lifting cylinder is fixed to the center of the top plate 7, and the axis of the top plate 7 is coaxial with the axis of the support platform 3, ensuring that the force exerted by the top plate 7 on the support platform 3 is uniform, further reducing the possibility of the support platform 3 tilting. Furthermore, the top plate 7 is also provided with a guide rod 71, the lower end of which movably passes through the guide hole 13 on the worktable 1, and the lower end of the guide rod 71 is provided with a limiting plate 72. Preferably, the guide rods 71 ​​are provided in two sets and arranged along the axis of the top plate 7, and the opposing ends of the limiting plates 72 at the lower ends of the two guide rods 71 ​​are connected and fixed to form a whole. In this case, the lifting height of the lifting cylinder 6 can be limited by the setting of the limiting plates 72, so as to avoid the top plate 7 from causing excessive compression and deformation of the support platform 3 when the support platform 3 rises to the highest point, and also to prevent the lifting cylinder 6 from separating from the screw 82, thus ensuring the stability of the equipment.

[0025] The lifting cylinder 6 is driven to rise and fall by a lifting drive mechanism 8. When the lifting drive mechanism 8 lifts and falls, it also drives the top plate 7 at the top of the lifting cylinder 6 to rise and fall. This allows the top plate 7 to push the support platform 3 upwards, or for the top plate 7 to fall, the support platform 3 to fall due to its own weight. Further, the lifting drive mechanism 8 includes a rotary motor 81, the output end of which is fixed with a screw 82. The screw 82 is rotatably mounted below the worktable 1 via a support frame 12, and the lifting cylinder 6 is threadedly engaged with the screw 82. Preferably, the screw 82 is connected to the support frame 12 via a bearing. In this case, the screw 82 can rotate, but is also vertically limited by the bearing. The support frame 12 supports the screw 82. Because the lifting cylinder 6 is prevented from rotating between itself and the mounting hole 11, it can only rise and fall vertically. When the rotary motor 81 drives the screw 82 to rotate, the screw 82 threadedly engages with the lifting cylinder 6, allowing the lifting cylinder 6 to move up and down, thereby driving the top plate 7 to move up and down.

[0026] In use, multiple detection cards are loaded into the card supply compartment 2. At this time, the photoelectric sensor 25 detects that there is a detection card in the card retrieval position of the card supply compartment 2. During the operation of the equipment, when the gripper removes the detection card from the retrieval position, the photoelectric sensor 25 detects that there is no detection card in the retrieval position. Then, the control program controls the rotary motor 81 to rotate, which drives the top plate 7 to rise through the lifting cylinder 6. The top plate 7 lifts the support platform 3, causing it to rise. Then, the detection card on the support platform 3 moves up until it is located in the retrieval position and is detected by the photoelectric sensor 25.
