Description

Technical Field

[0001] The present invention relates to the technical field of medical device machining, and particularly relates to an automated production line device for tracheal intubation printing and a product identification printing positioning and detection method. Background Art

[0002] Tracheal intubation is an important measure urgently used in cardiopulmonary resuscitation and the rescue process of critically ill patients with respiratory dysfunction. Tracheal intubation is an important rescue technique commonly used in first aid work, and is one of the most widely used, effective and rapid means in airway management. It is a basic skill that medical staff must master proficiently, and plays a crucial role in saving patients' lives and reducing the mortality rate. Medicine can timely aspirate tracheal secretions or foreign bodies, prevent foreign bodies from entering the respiratory tract, keep the airway unobstructed, perform effective artificial or mechanical ventilation, and prevent patients from suffering from hypoxia and carbon dioxide retention. Whether tracheal intubation is timely is directly related to the success or failure of rescue, the safe transfer of patients and the prognosis of patients.

[0003] The existing production and processing of tracheal intubation are often completed by workers with the assistance of some simple tooling, with low full automation degree, low production efficiency, high dependence on workers, and prone to safety accidents during printing. At the same time, due to the great influence of human factors on product quality, there is no corresponding visual precise positioning method during operations such as glottis line printing and product identification printing of products, resulting in a large number of defective printed products. In addition, there is no corresponding portable device to precisely perform operations such as cutting, inflatable hole drilling, and Murphy hole drilling on products, and there is no complete set of tracheal intubation printing solutions set on the production line device.

[0015] A product identification printing and positioning detection method for an automatic production line equipment for tracheal intubation printing, including:

[0016] Step 1: Loading the object to be inspected:

[0017] The pipe body is conveyed to the processing position through the conveying structure. The seventh linear module and the opposing linear module operate synchronously and drive the sixth jaw and the driven jaw to move forward. The sixth jaw cylinder and the driven jaw cylinder respectively drive the sixth jaw and the driven jaw to clamp the pipe body on the conveying structure; at this time, the second pipe pressing structure presses down and limits and resists the pipe body through the limiting block.

[0018] Step 2, Image acquisition:

[0019] The second rotating motor operates at 600 - 800 revolutions per minute, drives the sixth jaw cylinder and the sixth jaw installed on the sixth jaw cylinder to drive the pipe body to rotate through the coupling and the rotating shaft. At this time, the machine vision detection system is triggered, and the second detection camera performs image acquisition on the pipe body.

[0020] Step 3, Image Information Processing:

[0021] The machine vision detection system processes the collected images, converts the target to be measured into an image signal through a vision sensor, and transmits it to the image processing system to obtain the morphological information of the object to be measured.

[0022] Step 4, Detection and Judgment:

[0023] Based on the morphological information of the object to be measured obtained in Step 3, data calculation is performed. Taking the tube body's spare line as the reference line, the upper distance is the distance from the reference line to the top of the tube body's cross-section, and the lower distance is the distance from the reference line to the bottom of the tube body's cross-section. The sum of the upper distance and the lower distance is the tube diameter D. It is determined that when the difference between the upper distance and the lower distance is within ±0.02D, it indicates that the detection is qualified.

[0024] Step 5, Precise Positioning:

[0025] When the difference between the upper distance and the lower distance is within ±0.02D, the machine vision detection system responds quickly, immediately stops the operation of the second rotating motor, and then the system controls the second rotating motor to drive the tube body to rotate 90° again to identify the printing positioning position of the product logo.

[0026] The beneficial effects of the present invention are:

[0027] 1. By providing an automated production equipment for tracheal intubation printing, the production line automation operation of nine processing stations including feeding, cutting, glottis line printing, visual positioning, inflation hole drilling, product logo printing, ink cooling, Murphy hole drilling, and blowing debris of the tracheal intubation is realized. The overall equipment structure is reasonably designed, with a high degree of automation, greatly improving the production efficiency of the product and further ensuring the product qualification rate.

[0028] 2. By setting the first vision detection structure, the second vision detection structure, and the third vision detection structure, as well as the cooperating tube clamping and rotating structure, the precise positioning and identification of the spare line on the tube body can be achieved, and on this basis, the tube body can be adjusted by 90°, which is convenient for product processing, solves the technical problem of poor consistency caused by manual visual observation and positioning, improves the accuracy of the processing positions of the product inflation hole drilling, product logo printing, and Murphy hole drilling. In addition, the overall operation equipment has high consistency and small error, which can greatly improve the production quality of the product.

[0029] 3. By providing a detection and judgment method, a detection scheme, and a working principle for product mark printing positioning, the accuracy of its positioning and identification technology is further verified.

[0030] 4. By setting the tube body glottis line, the product identification printing device, and the glottis line and product identification printing structures respectively, and cooperating with the automation components to perform the printing operation on the tube body, efficient automatic and safe printing is achieved.

[0031] 5. By setting a blowing and cooling device after the product identification printing station, the ink liquid on the tube body can be quickly air-dried, preventing ink contamination and resulting in label confusion, and also shortening the production cycle.

[0032] 6. Each station of the automated equipment on this production line can process multiple products simultaneously, which can further improve production efficiency.

[0033] 7. By setting a tube pressing structure, it is ensured that the product tube does not displace during processing or flipping, further improving the processing accuracy.

[0034] 8. By setting arc-shaped grooves on the clamping jaws in the horizontal and vertical positions to cooperate with the product tube, a more relaxed and non-detachable clamping effect is achieved, that is, ensuring clamping and positioning without damaging the tube body.

Embodiment

[0052] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0053] As Figure 1-14 shown, an automated production line device for tracheal intubation printing includes nine major workstations: a tube body automatic loading device 1, a tube body automatic cutting device 2, a tube body glottis line printing device 3, a visual tube body positioning device 4, a tube body inflation hole punching device 5, a tube body product identification printing device 6, a tube body ink blowing and cooling device 7, a tube body Murphy hole punching device 8, and a tube body inner wall debris blowing device 9; the above workstations are sequentially arranged on the table top 100 to perform loading, cutting, glottis line printing, visual positioning, inflation hole punching, product identification printing, ink cooling, Murphy hole punching, and debris blowing operations on the tube body 101. Among them, the tube body automatic loading device 1 includes a tube body storage structure 13, a suction pipe structure 14, a vertical tube loading structure 15, a horizontal tube loading structure 16, and a transfer alignment structure 12; the suction pipe structure 14 drives the suction head 142 to operate through the first vertical cylinder 141 to adsorb the tube body 101 in the tube body storage structure 13; the vertical tube loading structure 15 includes a vertical tube loading cylinder 151 and a first gripper cylinder 152, which drives the first gripper cylinder 152 to operate through the vertical tube loading cylinder 151, and the first gripper cylinder 152 drives the first gripper 153 in the vertical position to clamp the tube body 101 in the suction head 142, and drives the tube body 101 to be transported to the transfer structure 12 through the horizontal tube loading structure 16. The transfer structure 12 is provided with a material groove 121 for placing the tube body 101, and an alignment cylinder 122 and an alignment baffle 123 for aligning the tube body 101. It also includes a first support frame 11 fixed on the table top 100, and the above suction pipe structure 14, vertical tube loading structure 15, horizontal tube loading structure 16, and transfer structure 12 are all fixed on the support frame 11.

[0054] Among them, the tube body product identification printing device 6 includes a second tube clamping and rotating structure 62, a second tube pressing structure 64, a second vision detection structure 65, and a product identification printing structure 61; the product identification printing structure 61 is installed on the support table frame 63, the second tube clamping and rotating structure 62 clamps the tube body 101, and the fourth vertical cylinder 641 in the second tube pressing structure 64 arranged directly above the second tube clamping and rotating structure 62 drives the pressing plate 642 to move downward, and the limiting block 643 provided at the bottom of the pressing plate 642 is used to perform a limiting operation on the tube body 101; at the same time, the second tube clamping and rotating structure 62 drives the tube body 101 to rotate, and the second detection camera 652 in the second vision detection structure 65 also arranged above the second tube clamping and rotating structure 62 is used to identify and position the prepared wire on the rotating tube body 101, and the vision detection structure 65 is also equipped with a second light source 651. The product identification printing structure 61 is provided with a sixth linear module 611 and an up-and-down printing cylinder 612 installed on the sliding part of the sixth linear module 611. The bottom of the up-and-down printing cylinder 612 is connected and fixed with a printing head 613. A printing ink plate 614 is arranged below the printing head 613. After the up-and-down printing cylinder 612 drives the printing head 613 to move downward and transfers the product identification ink mark on the printing ink plate 614 to the printing head 613, the sixth linear module 611 then shifts the printing head 613 to the position of the tube body 101 clamped by the jaw 623, and prints the product identification ink mark on the printing head 613 on the tube body 101.

[0055] Specifically, when the prepared wire is recognized, it is determined that the positioning is successful. Since the prepared wire on the tracheal intubation tube body 101 is deflected by 90° from the center line of the product identification mark, at this time, only the second tube clamping and rotating structure 62 needs to drive the tube body 101 to rotate another 90° to meet the printing conditions.

[0056] As Figure 15 shown, there is also a main line 10. The main line 10 is provided with a chain / belt type conveying structure for conveying the tube body 101 to each processing station. A fixture 102 for placing the tube body 101 is arranged on the conveying structure of the main line 10.

The active rotating device includes a seventh linear module 624 and a fixing plate mounted on the sliding part of the seventh linear module 624 for fixing a second rotating motor 621. The acting end of the second rotating motor 621 is connected with a sixth jaw cylinder 622, and the sixth jaw cylinder 622 acts on a sixth jaw 623 in the horizontal position; the driven rotating device includes an opposing linear module 625, and a fixing plate for fixing a driven jaw cylinder 626 is mounted on the sliding part of the opposing linear module 625, and the driven jaw cylinder 626 acts on a driven jaw 627 in the horizontal position; the seventh linear module 624 and the opposing linear module 625 respectively drive the sixth jaw 623 and the driven jaw 627 to move forward and clamp the pipe body 101, and the second rotating motor 621 drives the sixth jaw 623 and drives the driven jaw 627 to rotate, so as to realize the synchronous rotation of the pipe body 101.

[0058] As Figure 3 shown, the automatic pipe cutting device 2 includes a second support frame 21 mounted on the table board 100. A cutting structure 22, a pipe picking and placing structure 23 and a first linear module 24 are fixedly arranged on the second support frame 21; the pipe picking and placing structure 23 is mounted on the sliding part of the first linear module 24 and includes a pipe picking and placing cylinder 231. The acting end of the pipe picking and placing cylinder 231 is connected with a second jaw cylinder 232 for driving a second jaw 233 in the vertical position to clamp the pipe body 101; the first linear module 24 drives the clamped pipe body 101 to move to the cutting structure 22, and the cutting structure 22 is provided with a cutting knife hole 221 for removing the redundant material at the tail end of the pipe body 101.

[0059] As Figure 4As shown in the figure, the glottis line printing device 3 for the tube body includes a glottis line printing structure 31, a tube clamping structure 32 installed on the table top plate 100, and a first tube pressing structure 33 installed on the tube clamping structure 32. The tube clamping structure 32 is provided with a third linear module 321. A third jaw cylinder 322 is installed on the connecting plate of the sliding part of the third linear module 321 to drive the horizontal third jaw 323 to clamp the tube body 101 and move forward to the printing position. The first tube pressing structure 33 is arranged above the tube body 101 and is provided with a downward pressing cylinder 331 and a pressing wheel 332. The downward pressing cylinder 331 is used to drive the pressing wheel 332 to press down to apply a small force to the tube body 101. The glottis line printing structure 31 includes a second linear module 312 and a second vertical cylinder 314 installed on the sliding part of the second linear module 312. The acting end of the second vertical cylinder 314 is connected with a left-right moving cylinder 311, and the bottom acting end of the left-right moving cylinder 311 is connected with a printing head 313. Through the operation of the second linear module 312, the printing head 313 is driven to the oil cup 315, and after the printing head 313 dips the ink by the downward pressure of the second vertical cylinder 314, it returns, presses down again, and drives the printing head 313 to perform a circumferential glottis line printing on the tube body 101 through the left-right moving cylinder 311. Specifically, the left-right moving cylinder 311 moves horizontally left and right, driving the printing head 313 to perform flipping printing on the tube body 101.

[0060] As Figure 5 shown, the visual positioning device 4 for the tube body includes a third support frame 41 installed on the table top plate 100, a first visual detection structure 42 and a first tube clamping and rotating structure 43 installed on the third support frame 41. The first visual detection structure 42 includes a first light source 421 and a first detection camera 422. The first tube clamping and rotating structure 43 includes a fourth linear module 431. A first rotating motor 432 is installed on the connecting plate of the sliding part of the fourth linear module 431. One end of the first rotating motor 432 is connected with a fourth jaw cylinder 433 to drive the horizontal fourth jaw 434 to clamp the tube body 101.

[0067] Step 1: Load the object to be inspected:
