Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a detector for microcolumn gel cards. Background Technology

[0002] Microcolumn gel cards are widely used in pre-transfusion examinations such as blood typing and antibody screening. Currently, the interpretation of gel card results largely relies on manual visual observation, which suffers from problems such as high subjectivity, low efficiency, fatigue, and difficulty in standardization and data management.

[0003] Some existing automated testing equipment can only photograph the front of the gel card and cannot simultaneously collect and correlate the back of the card. This can result in the detection surface not being the main surface where the reaction occurs, leading to deviations or errors in the test results, requiring retesting or incorrect judgments.

[0004] Furthermore, a key technical challenge in automated inspection processes is how to stably and damage-free handle and grip thin, lightweight micropillar gel cards, ensuring their precise positioning at the imaging station. Ordinary robotic arms are prone to causing cards to slip or become damaged, and it's difficult to guarantee that the cards are presented to the camera in the same posture each time, affecting the consistency of image analysis. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a detector for micropillar gel cards. Through a composite gripping mechanism of pneumatic adsorption and mechanical clamping, it can reliably pick up and transfer micropillar gel cards, effectively preventing them from slipping, tilting or being damaged during movement, ensuring the safety and stability of the handling process, preparing for the installation and flipping of micropillar gel cards, realizing double-sided shooting of micropillar gel cards by a single camera, and achieving a high degree of automation.

[0006] The purpose of this utility model is achieved as follows: A micropillar gel card testing instrument includes a chassis, a loading box, an XYZ three-axis linear module, an industrial camera, and a gripping mechanism. The loading box is located on the bottom of the chassis, and the XYZ three-axis linear module is mounted on the top of the chassis. The moving end of the XYZ three-axis linear module is connected to the gripping mechanism, which transports and suspends the micropillar gel card to be tested at the camera's shooting position. The gripping mechanism includes a rotary cylinder, an open-end clamping cylinder, grippers, a mounting bracket, and a vacuum suction needle. The rotary cylinder is connected to the moving end of the XYZ three-axis linear module, and the moving end of the rotary cylinder is connected to the open-end clamping cylinder. The two output ends of the open-end clamping cylinder are symmetrically connected to the grippers. The grippers clamp the two ends of the micropillar gel card along its length. The vacuum suction needle vacuum adsorbs the non-porous area on the top surface of the micropillar gel card. The lens of the industrial camera is aimed at the front or back of the micropillar gel card.

[0007] Preferably, at least two vacuum suction needles are provided.

[0008] Preferably, the mounting bracket is fixed below the cylinder body of the open clamp cylinder. The mounting bracket is also provided with a sensor assembly, which includes a probe rod, a proximity switch and a proximity switch support rod.

The probe rod passes through the mounting bracket and protrudes from the bottom of the mounting bracket. The probe rod can slide up and down relative to the mounting bracket, and the probe rod is adapted to the proximity switch.

[0009] Preferably, an elastic buffer sheet is attached to the inner side of the gripper.

[0010] Preferably, each gripper has symmetrical limiting blocks on both sides to limit the width of the micropillar gel card.

[0011] Preferably, the industrial camera is fixed to a guide rod by a suspension rod, and the guide rod is fixed to the top of the chassis.

The back light source is located behind the camera shooting station and is fixed to the side wall of the chassis.

[0013] Preferably, the bottom surface of the chassis is also provided with a feeding box, which is located behind the feeding box.

[0014] The beneficial effects of this utility model are: Stable handling and gripping: The composite gripping mechanism of pneumatic adsorption and mechanical clamping can reliably pick up and transfer micropillar gel cards, effectively preventing them from slipping, tilting or being damaged during movement, ensuring the safety and stability of the handling process, preparing for the installation and flipping of micropillar gel cards, and enabling a single camera to take pictures of both sides of the micropillar gel cards. High-efficiency front and back image acquisition: The front and back of the micropillar gel card are flipped by a rotating cylinder, which enables the synchronous or rapid continuous acquisition of front and back images with one positioning of the micropillar gel card. The detection efficiency is high and the measurement accuracy is high. High degree of automation: The entire process, from loading, handling, taking photos to unloading and sorting, is completed automatically, freeing up manpower, reducing human error, and achieving standardization and intelligence in the testing process.

[0019] See Figure 1-3 This utility model relates to a detector for micropillar gel cards, including a chassis 1, a loading box 2, an XYZ three-axis linear module 3, an industrial camera 4, and a clamping mechanism. The loading box 2 is located on the bottom surface of the chassis 1 and is used to store the micropillar gel cards 5 to be tested. The XYZ three-axis linear module 3 is installed on the top of the chassis 1, and the moving end of the XYZ three-axis linear module 3 is connected to the clamping mechanism. The XYZ three-axis linear module 3 is used to drive the clamping mechanism to move in the X, Y, and Z directions. The clamping mechanism adopts a combination of adsorption and mechanical clamping. The method involves transporting and suspending the micropillar gel card to be tested at the camera shooting position. The clamping mechanism includes a rotary cylinder 6, an open clamping cylinder 7, grippers 8, a mounting bracket 9, and a vacuum suction needle 10. The rotary cylinder 6 is connected to the moving end of the XYZ three-axis linear module 3. The movable end of the rotary cylinder 6 is connected to the open clamping cylinder 7. The two output ends of the open clamping cylinder 7 are symmetrically connected to the grippers 8. The grippers 8 clamp the two ends of the micropillar gel card 5 along its length. An elastic buffer sheet 8.1 is attached to the inner side of the grippers 8 to ensure stable clamping without damaging the micropillar gel card.

[0020] The opening clamp cylinder 7 has a mounting bracket 9 below the cylinder body. The mounting bracket 9 is used to clamp the vacuum suction needle 10. There are at least two vacuum suction needles 10, which are used to adsorb the non-porous area on the top surface of the micropillar gel card 5.

[0021] The mounting bracket 9 is also equipped with a sensor assembly, which includes a probe rod 11, a proximity switch 12, and a proximity switch support rod 13. The proximity switch support rod 13 is fixed on the mounting bracket 9, and the proximity switch 12 is fixed on the proximity switch support rod 13. The probe rod 11 passes through the mounting bracket 9 and exits from the bottom of the mounting bracket 9. The probe rod 11 can slide up and down relative to the mounting bracket 9. The probe rod 11 is adapted to the proximity switch 12. When the probe 11 touches the non-porous area on the top surface of the micropillar gel card 5, the probe 11 rises to a position that the proximity switch 12 can detect. The proximity switch 12 sends a signal, and the vacuum suction needle 10 draws a vacuum to adsorb the non-porous area on the top surface of the micropillar gel card 5. At the same time, the open clamp cylinder 7 moves, and the grippers 8 clamp inward on both sides of the length direction of the micropillar gel card 5 under the control of the open clamp cylinder 7. Each gripper 8 has symmetrical limit blocks 8.2 on both sides to limit the width direction of the micropillar gel card 5.

[0022] The rotary cylinder 6 drives the entire clamping mechanism to rotate, thereby flipping the micropillar gel card 5 between its front and back sides.

[0023] The industrial camera 4 is fixed to the guide rod 15 by the hanging rod 14. The guide rod 14 is fixed to the top of the housing 1. The lens of the industrial camera 4 is aimed at the front or back of the micropillar gel card 5. In order to improve the clarity of the shooting, the industrial camera 4 is equipped with a front light source 16 and a back light source 17 to provide illumination. The front light source 16 is close to the industrial camera 4 and is located between the camera shooting station and the industrial camera 4. The back light source 17 is set behind the camera shooting station and fixed to the side wall of the housing 1.

[0024] The bottom surface of the chassis 1 is also provided with a feeding box (not shown in the figure). The feeding box 1 is located on the rear side of the feeding box and is used to classify and collect microcolumn gel cards according to the test results.

[0025] The controller is electrically connected to the XYZ three-axis linear module 3, rotary cylinder 6, open clamp cylinder 7 and industrial camera 4 to coordinate the sequential actions of each component.

[0026] Working principle: The operator places a batch of microcolumn gel cards 5 to be tested into the loading box 2; The control system is activated, driving the XYZ three-axis linear module 3 to move to the card-taking position. The gripping mechanism descends, and the vacuum suction needle 10 generates negative pressure by venting, adsorbing the non-porous area on the top surface of a micro-pillar gel card 5. At the same time, the flexible grippers 8 clamp the two sides of the card. The gripping mechanism picks up the micro-pillar gel card 5 from the feeding box 2 and moves it to the camera shooting position. The gripping mechanism adopts a combination of pneumatic adsorption and mechanical clamping, which can reliably pick up and transfer the micro-pillar gel card, effectively preventing it from slipping, tilting or being damaged during movement, and ensuring the safety and stability of the handling process. Industrial camera 4 takes a picture of the front of the micropillar gel card 5 at the camera shooting position. After the picture is taken, the rotary cylinder 6 rotates 180° and industrial camera 4 takes a picture of the back of the micropillar gel card 5 at the camera shooting position. Industrial camera 4 sends the captured image data to the controller. The controller receives the image data captured by the industrial camera, processes, analyzes and stores it. The clamping mechanism transports the micropillar gel card 5, which has been photographed from both sides, to the unloading box to complete the testing of the micropillar gel card.

[0027] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
