The discharge end of the labeling module 100 is connected to the feed end of the data collection module 200; the labeling module 100 and the data module are respectively connected to the control module 300 for communication; the data collection module 200 includes a roller conveying component 210, a first detection component, a posture adjustment component 220 and an information collection component 230; wherein the labeling component 110 is used to label the needle tube to be labeled, and to convey the labeled needle tube 500 to be collected to the roller conveying component; the roller conveying component 210 is used to convey the needle tube to be collected The needle tube 500 is transported to the collection area of ​​the information collection component 230, and the collected needle tube is transported to the packaging component 400 for packaging; the first detection component is used to detect the label position of the needle tube 500 to be collected, and send the detection result to the control module 300; the posture adjustment component 220 is used to drive the needle tube 500 to be collected to rotate after receiving the adjustment posture signal sent by the control module 300, so that the label on the needle tube is adjusted to the collection range of the information collection component 230; the information collection component 230 is used to identify and collect information on the label on the needle tube 500 to be collected, and send the collection result to the control module 300.

[0032] Since a labeling module 100, a data collection module 200 and a control module 300 are provided, and the data collection module 200 is provided with a roller conveying component 210, a first detection component, a posture adjustment component 220 and an information collection component 230, through the coordinated use of the above components, a fully automated process from labeling to data collection is realized, manual intervention is reduced, and production efficiency is greatly improved. Moreover, the waiting time and material handling costs of the intermediate links can be reduced through the collaborative work between the various modules. At the same time, only a label needs to be attached to any position of the needle tube body to realize information collection of the needle tube 500 to be collected, which greatly reduces the production cost and improves the production efficiency. It effectively solves the technical problem that multiple labels need to be attached to the needle tube in the prior art to collect information from the needle tube, and there are high production costs and low production efficiency.

[0033] Specifically, a labeling module 100 is provided for labeling the needle tubes to be labeled, thereby obtaining the needle tubes 500 to be collected, and the conveying assembly 120 of the labeling module 100 conveys the needle tubes 500 to be collected to the roller conveying assembly 210, and the single needle tubes 500 to be collected are sequentially placed in the middle of two adjacent rollers on the roller conveying chain of the roller conveying assembly 210, so that the needle tubes 500 to be collected can be stably placed on the roller conveying assembly 210, ensuring that the needle tubes 500 to be collected can be evenly arranged on the roller conveying assembly 210, and ensuring that the needle tubes 500 to be collected will not be offset on the roller conveying assembly 210, which is beneficial for the information collection assembly 230 to collect data on the needle tubes 500 to be collected. By setting a first detection component, such as an image acquisition device, a photoelectric sensor, etc., it is used to detect the orientation of the label on the needle tube 500 to be collected, that is, to detect whether the orientation of the label is within the recognizable range of the information acquisition component 230, and send the detection result to the control module 300, which is beneficial for the control module 300 to analyze and process the label orientation to determine whether the posture of the needle tube 500 to be collected needs to be adjusted. The posture adjustment signal sent by the control module 300 is received through the posture adjustment component 220, and the needle tube 500 to be collected is driven to rotate along its own central axis between two adjacent rollers on the roller conveyor component 210, so that the label on the needle tube 500 to be collected rotates toward the side facing the information collection component 230; wherein, the posture adjustment component 220 includes a mounting seat 221, a second servo motor 222 and a belt-rubbing component 223, the second servo motor 222 and the belt-rubbing component 223 are respectively arranged on the mounting seat 221, and are fixed to the top of the roller conveyor component 210 through the mounting seat 221, the second servo motor 222 is used to provide a power source for the belt-rubbing component 223, the belt-rubbing component 223 can move up and down relative to the roller conveyor component 210, and can drive the component to be collected to rotate along its own central axis. When the second servo motor 222 receives the posture adjustment signal sent by the control module 300, it drives the belt rubbing assembly 223 to move downward to the needle tube 500 to be collected, and drives the needle tube 500 to be collected to rotate through the synchronous belt of the belt rubbing assembly 223, so as to adjust the posture of the needle tube 500 to be collected, until the label on the needle tube 500 to be collected rotates to the collectible range of the information collection assembly 230, and sends the posture adjustment result to the control module 300. After receiving the posture adjustment result sent by the second servo motor 222, the control module 300 sends an information collection instruction to the information collection assembly 230, and uses the information collection assembly 230 to identify and collect information from the needle tube 500 to be collected.

[0034] In a preferred embodiment, the labeling module 100 includes a labeling component 110, a conveying component 120 and a blanking component 130; the feeding end of the conveying component 120 is connected to the discharging end of the labeling component 110, and the discharging end of the conveying component 120 is connected to the feeding end of the blanking component 130; the discharging end of the blanking component 130 is connected to the feeding end of the roller conveying component 210. Since the labeling component 110, the conveying component 120 and the blanking component 130 are provided, through the coordinated use of the above components, not only can the needle tube to be labeled be labeled, but also the labeled needle tube 500 to be collected can be orderly transferred to the roller conveying component 210, so as to collect information of the needle tube 500 to be collected, and the entire production process is coherent and efficient, which reduces the waiting and transfer time in the middle, and greatly improves the overall production efficiency.

[0035] Specifically, in the embodiment of the present application, the labeling assembly 110 is used to label the needle tube to be labeled, and the conveying assembly 120 includes an adjustable bracket, a servo drive assembly and two conveyor belts spaced apart from each other. The adjustable bracket is used to provide support for the servo drive assembly and the two conveyor belts, and the angle of the adjustable bracket can be adjusted according to actual needs. The servo drive assembly is used to drive the two conveyor belts to move, and the two conveyor belts are respectively clamped on both sides of the needle tube 500 to be collected, and drive the needle tube 500 to be collected to move toward the feed track 133 of the lower material assembly 130. On this basis, the needle tubes 500 to be collected can enter the feed track 133 of the lower material assembly 130 in the form of a queue, which can prevent the feed track 133 from being blocked, and ensure that the needle tubes 500 to be collected can enter the feed track 133 of the lower material assembly 130 in an orderly manner, thereby improving production efficiency. In addition, the width of the conveying trough can be adjusted by adjusting the distance between the two conveyor belts to adapt to different types of syringes, thereby improving the adaptability range of the medical syringe intelligent collection system.

[0036] In a preferred embodiment, the unloading assembly 130 includes a first servo motor 131, a dial wheel 132, a feed track 133 and an arc-shaped baffle 134; the first servo motor 131 is connected to the dial wheel 132 and drives the dial wheel 132 to rotate; a plurality of grooves 132A for placing the needle tubes 500 to be collected are arranged at equal intervals on the outer peripheral wall of the dial wheel 132; the feed end of the feed track 133 is connected to the discharge end of the conveying assembly 120, and the discharge end of the feed track 133 corresponds to the outer peripheral wall of the dial wheel 132; one end of the arc-shaped baffle 134 is connected to one side of the discharge end of the feed track 133, and the other end extends along the rotation direction of the dial wheel 132 to above the feed end of the roller conveying assembly 210, and a distance is arranged between the arc-shaped baffle 134 and the dial wheel 132. Since the unloading assembly 130 is provided with a first servo motor 131, a dial wheel 132, a feed track 133 and an arc-shaped baffle 134, through the coordinated use of the above components, not only can the needle tubes 500 to be collected be unloaded in an orderly manner to ensure that the number of needle tubes 500 to be collected placed each time is consistent, but also the needle tubes 500 to be collected can be guided to smoothly enter between two adjacent rollers on the roller conveying assembly 210 to achieve precise unloading.

[0037] Specifically, the first servo motor 131 provides power to the thumbwheel 132, and the control module 300 controls the first servo motor 131 to control the rotation speed and angle of the thumbwheel 132, so that different unloading speeds and rhythms can be achieved to meet the overall needs of the production line. A groove 132A is provided on the outer peripheral wall of the thumbwheel 132 to place a single needle tube 500 to be collected output by the feed track 133. As the thumbwheel 132 rotates, the needle tubes 500 to be collected can be transported one by one to the middle of two adjacent rollers on the roller conveying assembly 210, which can not only ensure that the needle tubes 500 to be collected can be evenly arranged and unloaded in an orderly manner, but also ensure that the number of needle tubes 500 to be collected placed each time is consistent. The feeding track 133 connects the conveying assembly 120 and the thumbwheel 132, which plays a role of transition and guidance. The feeding track 133 extends obliquely downward toward the side close to the thumbwheel 132, which can ensure that the needle tube 500 to be collected smoothly enters the outer peripheral wall of the thumbwheel 132 from the conveying assembly 120 and can be placed flat in the groove 132A of the thumbwheel 132. By setting an arc-shaped baffle 134 extending along the rotation direction of the thumbwheel 132 to the upper side of the feeding end of the roller conveying assembly 210, not only can the needle tube 500 to be collected be guided to smoothly enter the middle of two adjacent rollers on the roller conveying assembly 210 to achieve accurate feeding, but also can prevent the needle tube 500 to be collected from falling off, ensuring the stable transportation of the needle tube 500 to be collected.

[0038] In a preferred embodiment, a second detection component for detecting whether a needle tube 500 to be collected enters the feed track 133 is provided on the feed track 133. By providing the second detection component on the feed track 133, it is possible to detect in real time whether a needle tube 500 to be collected enters the feed track 133. Once the needle tube 500 to be collected is detected, it is possible to ensure that the first servo motor 131 is started in time and drives the dial wheel 132 to rotate, so as to realize the subsequent unloading operation, and ensure that it operates normally only when there is a needle tube 500 to be collected. This can not only improve the degree of automation of production, but also avoid idling when there is no needle tube 500 to be collected entering the feed track 133, reduce energy waste, avoid unnecessary wear, and extend the service life of the unloading component 130. At the same time, by detecting whether a needle tube 500 to be collected enters, the production progress can be accurately grasped, and problems in the production process, such as needle tube blockage, poor delivery, etc., can be discovered in time, so that measures can be taken in time to make adjustments and ensure the stability of the production process. In a preferred embodiment, the feed end of the roller conveying assembly 210 is provided with a third detection assembly for detecting whether there are needle tubes 500 to be collected on the thumbwheel 132. Since the third detection assembly is provided, it is possible to monitor in real time whether there are needle tubes 500 to be collected entering the thumbwheel 132. When the needle tubes 500 to be collected are detected, it is possible to ensure that the roller conveying assembly 210 is started in time and performs subsequent conveying operations, which can not only improve the degree of automation of production, but also avoid idling when there are no needle tubes 500 to be collected entering, reduce energy waste, avoid unnecessary wear, and extend the service life of the roller conveying assembly 210.

[0039] In a preferred embodiment, the data acquisition module 200 also includes a handling robot 240 for taking out the collected needle tubes to the packaging component 400. By arranging a handling robot 240 on one side of the roller conveyor assembly 210, the task of transporting the collected needle tubes from the production area to the feeding belt conveying station of the packaging component 400 can be automatically completed without manual intervention, which greatly improves production efficiency. In the embodiment of the present application, the handling robot 240 adopts a SCARA (Selective Compliance Assembly Robot Arm) robot. By utilizing the high-precision positioning capability of the SCARA robot, the needle tube can be accurately taken out from the collection position and placed on the feeding belt conveying station of the packaging component 400, and the needle tube can be taken out and placed in a short time. The task is conducive to improving production efficiency and meeting the needs of large-scale production. In addition, the roller conveying assembly 210 is also provided with a leveling assembly 250 on one side of the handling robot 240. The leveling assembly 250 is used to level the collected syringes so that the gripping fixture of the handling robot 240 can more smoothly adsorb the syringes, so that the syringes can be transported to the feeding belt conveying station of the packaging assembly 400, thereby reducing adsorption failures caused by uneven syringes, improving the handling efficiency, and speeding up the entire production process.

The conveying component 120 of the labeling module 100 is used to convey the labeled needle tube 500 to be collected to the feeding track 133. When the second detection component detects that the needle tube 500 to be collected enters the feeding track 133, the detection result is sent to the control module 300 to control the first servo motor 131 to drive the dial 132 to rotate.

After entering the collection area, it is beneficial for the first detection assembly to detect the label position on the needle tube to be detected, thereby improving the detection efficiency and facilitating the posture adjustment of the posture adjustment assembly 220.

[0044] Step S3, obtaining the detection result sent by the first detection component, and analyzing the detection result to obtain label information; specifically includes the following sub-steps: Step S31, using an image acquisition device to acquire a needle tube posture image of the needle tube 500 to be acquired in the acquisition area.

[0045] The needle tube posture image in this step includes an image of a complete label displayed on one side of the needle tube facing the information collection component 230, an image of a partial label displayed on one side of the needle tube facing the information collection component 230, and an image of no label displayed on one side of the needle tube facing the information collection component 230. The specific setting position and shooting method of the image acquisition device can be set according to practical scenarios and requirements. As long as the control component can obtain the needle tube posture image sent by the image acquisition device, this embodiment does not impose any restrictions on this. Step S32: grayscale and filter the needle tube posture image to obtain a needle tube posture enhanced image.

[0046] Specifically, the needle tube posture image is grayed to obtain a gray image, and then the gray image is Gaussian filtered to remove noise interference, making the image smoother and reducing the influence of noise on edge detection.

[0047] Step S33: Use the Canny edge detection operator to perform edge detection on the needle tube posture enhanced image to obtain the label edge information of the needle tube 500 to be collected in the needle tube posture image.

[0048] Specifically, the gradient amplitude and direction of each pixel in the needle tube posture enhanced image are calculated using the first-order partial derivative finite difference. The gradient amplitude is non-maximum suppressed, and the gradient value outside the local maximum is set to 0 to refine the edge and remove false edge points. Double threshold detection is used to determine the true edge points. Two high and low thresholds are set. Pixels with gradient amplitudes greater than the high threshold are determined as strong edge points, those less than the low threshold are determined as non-edge points, and pixels between the two and connected to the strong edge points are determined as edge points. By connecting the edge points, an edge image is obtained. The obtained edge image is analyzed. Since the label usually has a relatively regular edge shape, it can be judged based on the continuity of the edge, shape characteristics, etc. For example, the edge of the label may appear in a specific shape such as a rectangle or a circle. The contour in the edge image is detected using a contour detection algorithm. For each detected contour, its area, perimeter, rectangularity and other features are calculated. According to the specific features of the label, such as size, shape, etc., the contour of the label is identified from the detected contour. For example, if the label is rectangular, it can be determined whether it is a label contour by judging whether the rectangularity of the contour is within a certain range. Once the outline of the label is determined, the position information of the label in the image is determined by calculating the center position, bounding box and other information of the outline.

[0049] Step S4: Compare the label information with the preset information to determine the label status of the needle tube 500 to be collected in the detection result.

[0050] It can be understood that the purpose of this step is to allow the control module 300 to compare the label edge information obtained by image processing with the preset information, determine the label position in the needle tube posture image, and thus automatically adjust the position and orientation of the label on the needle tube 500 to be collected. In this step, the control module 300 can read the preset information from the file pre-stored in the storage device, and the preset information is that there is a label on the side of the needle tube facing the information collection component 230 and the label is displayed completely. Compare the label information with the preset information to determine the label situation in the detection result. Specifically, according to the label information and the preset label information in the preset information, it is determined whether the needle tube 500 to be collected in the collection area has a preset label and the label is displayed completely. This step can detect whether the label is on the side of the needle tube 500 to be collected facing the information collection component 230 (that is, the side that can be recognized by the information collection component 230) and whether it is displayed completely. If so, it is determined that the label of the needle tube 500 to be collected in the collection area is displayed correctly, that is, the label can be recognized by the information collection component 230, and there is no need to adjust the posture of the needle tube 500 to be collected. If not, it is determined that the label of the needle tube 500 to be collected in the collection area is displayed incorrectly, that is, the label is located on the side of the needle tube 500 to be collected that is away from the collection area or is partially displayed in the collection area. The label cannot be recognized by the information collection component 230, and the posture of the needle tube 500 to be collected needs to be adjusted.

[0051] Step S5: When the label status is a label display error, the posture adjustment component 220 is controlled to perform a posture adjustment operation on the needle tube 500 to be collected being detected.

[0052] Specifically, the purpose of this step is to adjust the posture of the needle tube 500 to be collected whose label cannot be recognized by the information collection component 230, that is, the label is located on the side of the needle tube 500 to be collected that is away from the collection area or is partially displayed in the collection area, so that the label on the needle tube 500 to be collected is turned into the collection area, so that the information collection component 230 can recognize the label and collect information.

[0053] In summary of the above steps, by labeling the needle tube to be labeled, and sending the labeled needle tube 500 to be collected to the collectible area of ​​the information collection component 230 through the roller conveying component 210 for data collection, a fully automated process from labeling to data collection is realized, reducing manual intervention and greatly improving production efficiency. At the same time, by using an image acquisition device to detect the label on the needle tube 500 to be collected, the edge, shape and characteristics of the label can be accurately identified, which greatly improves the accuracy of the detection, and is conducive to the control module 300 accurately analyzing the direction of the label on the needle tube 500 to be collected, so as to determine whether it is necessary to adjust the posture of the needle tube 500 to be collected. When it is necessary to adjust the posture of the needle tube 500 to be collected, the posture adjustment component 220 is controlled to drive the needle tube 500 to be collected to rotate, so as to realize the rotation of the label into the collectible range of the information collection component 230, so that the information collection component 230 can identify the label and collect data. Therefore, it is not necessary to stick multiple labels on the needle tube, and information collection can be realized for the needle tube 500 to be collected, which greatly reduces the production cost and improves the production efficiency. The invention effectively solves the technical problem that the prior art needs to stick multiple labels on the needle tube in order to collect information about the needle tube, which has high production cost and low production efficiency.

[0054] Embodiment 3 This embodiment provides a medical needle tube intelligent collection method, which differs from the second embodiment only in step S3 and step S4. The other processes are the same as the second embodiment and will not be repeated here. In step S3, the first detection component is a photoelectric sensor, which obtains the detection result sent by the photoelectric sensor and analyzes the detection result to obtain the label information, which specifically includes the following sub-steps: Step S31: Use a photoelectric sensor to transmit a light signal with a fixed period and duty cycle to the needle tube 500 to be collected in the collection area, and convert the reflected signal received by the photoelectric sensor into a voltage signal.

[0055] The optical signal can be a light beam of a specific wavelength. By setting a fixed period and duty cycle, it can avoid overlapping with other interference signals, and can control the intensity and duration of the signal to ensure the stability and recognizability of the signal. When the optical signal is irradiated onto the needle tube 500 to be collected, reflection occurs. The photoelectric sensor receives the reflected optical signal and converts it into a voltage signal for subsequent processing and analysis.

[0056] Step S32: filter and amplify the voltage signal to obtain a tag detection signal.

[0057] Specifically, in this step, the converted voltage signal is filtered to remove noise and interference signals, which helps to improve the accuracy of detection. By using an amplifier circuit to amplify the voltage signal, the obtained tag detection signal can be more easily identified and processed by the control module 300.

[0058] In step S4, the label information is compared with the preset information to determine the label status of the needle tube 500 to be collected in the detection result.

[0059] It can be understood that the purpose of this step is to compare the label detection signal obtained by the photoelectric sensor with the preset information for the control module 300 to determine the label position of the needle tube 500 to be collected, so as to automatically adjust the position and orientation of the label on the needle tube 500 to be collected. In this step, the control module 300 can read the preset information from the file pre-stored in the storage device. The preset information is the expected signal characteristic parameters of the label at different positions, including the signal strength range, shape feature range, etc. The label information is compared with the preset information to determine the label situation in the detection result. Specifically, since the label is usually a specific shape such as a rectangle or a circle, the control module 300 can determine the label position according to the extracted signal shape feature. For example, if the label is rectangular, the intensity distribution of the light signal at different positions will show a specific rectangular shape feature. When the intensity distribution of the light signal received by the sensor conforms to the rectangular feature, the approximate position and direction of the label can be determined. Therefore, by matching the extracted signal shape feature with the shape feature templates corresponding to the preset various label positions, the closest shape feature template is determined by comparing the similarity, so as to infer the position of the label, and then determine whether the needle tube 500 to be collected in the collection area has a preset label and the label is displayed completely. If so, it is determined that the label display of the needle tube 500 to be collected in the collection area is correct, that is, the label can be recognized by the information collection component 230, and there is no need to adjust the posture of the needle tube 500 to be collected. If not, it is determined that the label display of the needle tube 500 to be collected in the collection area is wrong, that is, the label is located on the side of the needle tube 500 to be collected away from the collection area or is partially displayed in the collection area. The label cannot be recognized by the information collection component 230, and the posture of the needle tube 500 to be collected needs to be adjusted.

[0060] In summary of the above steps, by labeling the needle tube to be labeled, and sending the labeled needle tube 500 to be collected to the collectable area of ​​the information collection component 230 through the roller conveying component 210 for data collection, a fully automated process from labeling to data collection is realized, reducing manual intervention and greatly improving production efficiency. At the same time, by using a photoelectric sensor to detect the label on the needle tube 500 to be collected, the label position information of the needle tube 500 to be collected can be quickly detected, which greatly improves the detection speed, and is conducive to the control module 300 to quickly analyze the direction of the label on the needle tube 500 to be collected to determine whether the posture of the needle tube 500 to be collected needs to be adjusted. When the posture of the needle tube 500 to be collected needs to be adjusted, the posture adjustment component 220 is controlled to drive the needle tube 500 to be collected to rotate, so as to realize turning the label into the collectable range of the information collection component 230, so that the information collection component 230 can identify the label and collect data. Therefore, it is not necessary to stick multiple labels on the needle tube to realize information collection of the needle tube 500, which greatly reduces the production cost and improves the production efficiency. It effectively solves the technical problem of high production cost and low production efficiency in the prior art that multiple labels need to be stuck on the needle tube to collect information of the needle tube.
