technical field

The present application relates to medical consumables, in particular to a medical consumable assembly detection component, a detection device and a detection method thereof.

Background technique

Medical care, education and elderly care are the three major needs in the field of people's livelihood. If people want to obtain good medical resources, they not only need to train highly skilled medical staff, but also need qualified medical equipment. As a type of medical device, medical consumables refer to consumable devices and equipment used for diagnosis, treatment, health care, rehabilitation, etc. With the advancement of technology, the production of medical consumables is gradually automated, thereby improving the safety performance and production efficiency of medical consumables. Medical consumables are often not composed of a single material, but assembled from multiple materials. Therefore, in the automated production process of medical consumables, each material of medical consumables needs to be automatically assembled. However, at present, there is no detection of whether the various materials of medical consumables are assembled correctly, which needs to be improved.

Contents of the invention

In view of this, it is necessary to provide an improved medical consumable assembly detection component, detection device and detection method thereof. The medical consumable assembly detection component can detect whether each material is correctly assembled. The medical consumable assembly detection device adopting the medical consumable assembly detection component can detect whether each material is correctly assembled. This detection method can detect whether each material is assembled correctly.

The present application firstly provides a medical consumable assembly detection assembly, including a probe and a detection part, the detection part detects the position of the probe after it moves under the action of the material, and the probe includes a matching part that can be inserted into a material accommodating cavity.

By adopting the above technical solution, compared with the unassembled material, the depth at which the mating portion is allowed to be inserted into the accommodating cavity is different for the assembled material. Compared with the material that has not been correctly assembled, the depth that allows the mating portion to be inserted into the accommodating cavity is also different for the material that has been correctly assembled. The probe will move under the action of the material, so the different depths of the mating part inserted into the accommodating cavity will lead to different positions of the probe after it moves under the action of the material. The detection part can detect different positions of the probe, so that it can be judged whether the material is correctly assembled according to the detection result of the detection part. If the detection part is used to directly detect whether the material is assembled correctly, on the one hand, there will be burrs in the cavity, which will interfere with the detection of the detection part, and easily lead to inaccurate detection results. On the other hand, when the material is non-transparent, it may Direct detection by visual recognition is not possible. Therefore, the position of the probe is used to judge whether the material is assembled correctly, so that it can be applied to both transparent material and non-transparent material, and can avoid burrs and other influences on the detection results.

In one embodiment of the present application, the medical consumables assembly detection assembly further includes a mounting table, and the probe further includes a main body connected to the matching portion, and the main body is guided by the mounting table relative to the The mounting table moves.

By adopting the above technical solution, when the depths of the fitting parts inserted into the accommodating cavity are different, the main body will move to different positions under the guidance of the installation platform.

In one embodiment of the present application, the installation platform is provided with a movable hole passing through the installation platform, and the main body part is located in the movable hole and can move along the movable hole.

By adopting the above technical solution, the movable hole is used to guide the movement of the main body relative to the installation platform, and the structure is simple and the cost is low.

In one embodiment of the present application, the probe further includes a detection part connected to the main body, and the detection part and the matching part are located on both sides of the installation platform along the axial direction of the active hole , the detection part can move along the axial direction of the active hole to abut against one side of the mounting table along the axial direction of the active hole.

By adopting the above technical solution, the detection part abuts against one side of the installation platform along the axial direction of the movable hole, so that the position of the main body after moving along the movable hole is limited by the detection part. Therefore, when the side where the installation platform abuts against the detection part is the upper side of the installation platform, the matching part is located at the lower side of the installation platform, and at this time the main body will move upwards under the action of the material. Therefore, when the material loses its effect on the mating part, the main part will move downwards to reset under the action of its own gravity, and the detection part can limit the downward movement position of the main part.

In one embodiment of the present application, the probe further includes a limiting portion connected to the main body, and the limiting portion and the detecting portion are located on the axial side of the installation platform along the movable hole. On both sides, the limiting part can move along the axial direction of the movable hole to abut against one side of the installation platform along the axial direction of the movable hole.

By adopting the above technical solution, the limiting portion abuts against one side of the installation platform along the axial direction of the movable hole, so that the position of the main body after moving along the movable hole is limited by the limiting portion. At the same time, the cooperation of the limiting part and the detecting part can limit the movement range of the main part along the movable hole.

In one embodiment of the present application, the installation platform includes a connected movable part and a linkage part, the movable hole is disposed on the movable part, and the detection part is connected to the linkage part.

In one embodiment of the present application, the medical consumable assembly detection assembly further includes a driving member, and the driving member drives the installation platform to move to a preset position along the axial direction of the movable hole.

By adopting the above technical solution, when the material is moved in place, it is usually difficult for the matching part to be inserted into the accommodating cavity. Therefore, a driving member is required to drive the installation platform to move, so that the fitting part can be inserted into the receiving cavity after being moved. However, if the matching part moves with the mounting table, but the detection part does not move with the installation table, the distance between the detection part and the probe will change, thereby affecting the detection result. Therefore, the detection part is connected with the linkage part, so that the detection part can also move along with the installation platform, thereby ensuring that the distance between the detection part and the probe does not change during the movement of the installation platform, thereby ensuring the accuracy of the detection structure.

In one embodiment of the present application, the medical consumable assembly detection assembly further includes a frame, and the driving member is installed on the frame.

In one embodiment of the present application, the detection element is located in the moving direction of the probe. The present application further provides a medical consumable assembly detection device, including the above-mentioned medical consumable assembly detection assembly, the number of the medical consumable assembly detection assembly is set in multiples, and the materials are sequentially detected by a plurality of the medical consumable assembly detection assemblies .

The present application also provides a medical consumable assembly detection method, including the following steps:

Step 1: Control the probe to move to the accommodating cavity where the matching part is inserted into the material, and use the detection piece to detect the position of the probe at this time, which is recorded as _X1 ;

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs. The terms used herein in the description of the application are only for the purpose of describing specific implementations, and are not intended to limit the application. As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.

The embodiment of the present application firstly provides a medical consumable assembly testing assembly, including a frame 100 , an installation platform 200 , a driving part 300 , a probe 400 , and a testing part 500 .

The driver 300 is fixed on the frame 100 and connected to the installation platform 200 , so that the driver 300 can drive the installation platform 200 to move to a preset position relative to the frame 100 . The driver 300 can be an air cylinder or an electric cylinder.

The installation stand 200 includes a linkage part 210 and a movable part 220 connected thereto. In the specific embodiment shown in FIG. 1 , the linkage part 210 and the movable part 220 are L-shaped as a whole. The movable part 220 is provided with a movable hole 221 passing through the movable part 220 .

The detecting element 500 is fixedly connected to a side of the linkage part 210 facing the movable part 220 . The detecting part 500 adopts a laser sensor or a distance sensor.

The probe 400 includes a detection part 410 , a main body part 420 and a matching part 430 connected in sequence. The outer diameter of the main body 420 is smaller than the inner diameter of the movable hole 221 , so that the main body 420 can pass through the movable hole 221 and move along the movable hole 221 . The detection part 410 and the matching part 430 are located on both sides of the movable part 220 along the axial direction of the movable hole 221 . After the movable part 220 moves along the movable hole 221 , the detection part 410 can move along with the movable part 220 to abut against one side of the movable part 220 in the axial direction. In some embodiments, the probe 400 further includes a limiting part 440 connected to the main body part 420 . The detecting part 410 and the limiting part 440 are located on both sides of the movable part 220 along the axial direction of the movable hole 221 . When the main body 420 moves along the movable hole 221, the detecting part 410 and the limiting part 440 move along with the movable part 220 until either the detecting part 410 abuts against one axial side of the movable part 220, or the limiting part 440 and the movable part The other side in the axial direction of the portion 220 abuts against it. Therefore, the movement range of the main body part 420 relative to the movable part 220 is limited by the detection part 410 and the limit part 440 . In the specific embodiment shown in FIG. 1 , the outer diameters of the detection part 410 , the main body part 420 and the matching part 430 gradually become smaller. Wherein, the outer diameter of the detection part 410 is larger than the inner diameter of the movable hole 221 , so the detection part 410 cannot pass through the movable hole 221 . The outer diameter of the limiting portion 440 is also larger than the inner diameter of the movable hole 221 , so the limiting portion 440 cannot pass through the movable hole 221 .

The detection part 410 is connected to the end of the main body part 420 , and the detection part 410 is closer to the detection part 500 than the main body part 420 . The detection part 500 is aligned with the center of the detection part 410 and the detection part 410 is located in the moving direction of the detection part 410 . In the specific embodiment shown in FIG. 1 , the detection part 500 is located above the detection part 410 , and the detection part 410 , the main body part 420 , the limit part 440 and the matching part 430 are sequentially connected from top to bottom. The matching part 430 can be inserted into the accommodation cavity of the material 600, so that the material 600 can act on the matching part 430 and drive the main body part 420 to move along the axial direction of the movable hole 221, and then drive the detection part 410 to move along the axial direction of the movable hole 221. The detection part 500 can detect the position of the detection part 410 after the movement.

Referring to Figure 1, the working process of the assembly and detection components of medical consumables is explained:

The material 600 moves to the right below the matching portion 430 along with the carrier 700 , and the driving member 300 drives the installation platform 200 to move vertically downward relative to the frame 100 to a preset position. During the downward movement of the installation platform 200 , the matching portion 430 first moves downward to be inserted into the accommodating cavity. Subsequently, the installation platform 200 continues to move downwards, but the matching part 430 is blocked by the material 600 and no longer moves downwards, so it is equivalent to the matching part 430 moving upwards relative to the installation platform 200, thereby driving the detection part 410 to move upwards relative to the installation platform 200 . When the installation platform 200 moves to a preset position, the detection part 500 detects the position of the detection part 410 , that is, the distance that the detection part 410 moves upward relative to the installation platform 200 . After the detection is completed, the driving member 300 drives the installation platform 200 to move vertically upward relative to the frame 100 to a preset position. During the upward movement of the installation platform 200 , the matching portion 430 first moves downward relative to the installation platform 200 . Subsequently, the mounting table 200 continues to move upwards, and the detection part 410 abuts against the upper side of the movable part 220, thereby driving the detection part 410 to move upwards, thereby driving the matching part 430 to move upwards through the main body part 420 and to leave the accommodating cavity.

At this time, the material 600 can move to the assembly station along with the carrier 700 . After the assembly of the material 600 is completed, the material 600 moves to the right below the matching portion 430 along with the carrier 700 again, and the above-mentioned detection steps are repeated. According to the comparison between the position of the detection part 410 after the material 600 is assembled and the position of the detection part 410 before the material 600 is assembled, it is judged whether the material 600 is correctly assembled.

In addition, before the installation platform 200 moves downward, the detection part 500 can detect the position of the detection part 410, so that the position of the detection part 410 when the material 600 is not assembled can be compared with the position of the detection part 410 before the installation platform 200 moves downward, and it can be judged Whether the material 600 is located directly below the mating part 430 .

Compared with the unassembled material 600 , the assembled material 600 allows the mating portion 430 to be inserted into the accommodating cavity to a different depth. Compared with the material 600 that has not been correctly assembled, the material 600 after correct assembly allows the mating portion 430 to be inserted into the receiving cavity at a different depth. The probe 400 will move under the action of the material 600 , so the different depths of the fitting portion 430 inserted into the accommodating cavity will result in different positions of the probe 400 after moving under the action of the material 600 . The detection part 500 can detect different positions of the probe 400 , so that it can be judged whether the material 600 is correctly assembled according to the detection result of the detection part 500 . If the detection part 500 is used to directly detect whether the material 600 is correctly assembled, on the one hand, there will be burrs in the accommodation cavity, which will interfere with the detection of the detection part 500, and easily lead to inaccurate detection results; on the other hand, when the material 600 is non-transparent When the material is used, it cannot be directly detected by visual recognition. Therefore, the position of the probe 400 is used to judge whether the material 600 is assembled correctly, so that it can be applied to both the material 600 made of transparent material and the material 600 made of non-transparent material, and can avoid burrs and other influences on the detection results.

When the material 600 is moved into place, it is usually difficult for the matching portion 430 to be inserted into the receiving cavity. Therefore, the driving member 300 is required to drive the mounting table 200 to move, so that the matching portion 430 can be inserted into the receiving cavity after being moved. However, if the matching part 430 moves with the installation platform 200 but the detection part 500 does not move with the installation platform 200, the distance between the detection part 500 and the probe 400 will change, thereby affecting the detection result. Therefore, the detection part 500 is connected with the linkage part 210, so that the detection part 500 can also follow the movement of the installation platform 200, thereby ensuring that the distance between the detection part 500 and the probe 400 does not change during the movement of the installation platform 200, thereby ensuring the integrity of the detection structure. accuracy. In some embodiments, if the material 600 moves directly under the matching portion 430 along with the carrier 700 , the material 600 can move to the matching portion 430 to be inserted into the receiving cavity, and the installation platform 200 does not need to move at this time.

It can be understood that the movable part 220 may no longer be provided with the movable hole 221 , but the main part 420 and the movable part 220 are connected through slide rails. At the same time, limit blocks are provided at both ends of the slide rail to limit the sliding range of the main body 420 along the slide rail.

It can be understood that the detecting element 500 may also use a displacement sensor. At this time, the probe 400 can be separated from the movable part 220, but installed on the displacement sensor. The probe 400 can move relative to the displacement sensor under the action of the material.

Embodiments of the present application further provide an assembly detection device for medical consumables, including the assembly detection assembly for medical consumables according to any of the above embodiments. There are multiple detection components for medical consumable devices, and the material 600 is detected by multiple assembly detection components for medical consumables. Compared with the material 600 before assembly and the material 600 after assembly are detected by the same medical consumable assembly detection component, when multiple medical consumable assembly detection components are provided, the material 600 can pass through multiple medical consumable assembly detection components in sequence, The position of the probe 400 detected by different medical consumable assembly detection components is compared to determine whether the material 600 is correctly assembled.

The embodiment of the present application also provides a medical consumable assembly detection method, including the following steps:

Step 1: Control the probe 400 to move to the accommodating cavity where the mating part 430 is inserted into the material 600, and use the detection part 500 to detect the position of the probe 400 at this time, which is marked as _X1 ;

Step 2: Control the matching part 430 of the probe 400 to withdraw from the accommodating cavity of the material 600;

Step 3: Assembling the material 600;

Step 4: Control the probe 400 to move to the matching part 430 and the assembled material 600, and use the detection part 500 to detect the position of the probe 400 at this time, which is marked as X ₂ ;

Step 5: Judging whether the material 600 is assembled in place according to the comparison between the difference ΔX _actual and the standard deviation ΔX _standard between X ₁ and X ₂ .

When a medical consumable device detection component is used to run the detection method, the detection part 500 in step 1 and step 4 is the same. When multiple medical consumable device detection components are used to run the detection method, the detection parts 500 in Step 1 and Step 4 may or may not be the same. At this time, if the detection part 500 in step 1 and step 4 is the same, multiple detection components of medical consumable devices can detect multiple materials at the same time. If the detection piece 500 in step 1 and step 4 is not the same, the material is tested by the detection piece 500 in step 1 and the detection piece 500 in step 4 in sequence. Finally, when using multiple detection components of medical consumable devices to run the detection method, the detection efficiency can be improved, thereby finally improving the production efficiency of medical consumables.

To make the description concise, all possible combinations of the technical features in the above-mentioned embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, should be considered as within the scope of this specification.
