Description

Technical Field

[0001] This utility model relates to the field of airtightness testing technology, and in particular to an automated airtightness testing device for hoses. Background Technology

[0002] Anesthesia tubes are indispensable core medical devices in modern medicine, especially in surgery and critical care, ensuring airway patency and patient safety. With advancements in anesthesiology, minimally invasive surgery (such as laparoscopy), interventional diagnostic and treatment techniques, and increased focus on postoperative patient comfort (such as reducing sore throat), high-performance, specialized endotracheal tubes for anesthesia are constantly emerging to meet the needs of different patients (newborns, children, adults), different surgical positions (such as prone surgery), and special scenarios (such as difficult airways). These include nasal intubation, reinforced tubes, and double-lumen endotracheal tubes. Anesthesia tubes are the cornerstone of the safe implementation of modern anesthesia techniques and critical care respiratory management. Their widespread application profoundly reflects the progress of human medicine in precision, safety, and minimally invasive procedures, and they are essential key medical consumables for ensuring the successful execution of various complex surgeries and saving the lives of critically ill patients.

[0003] As an indispensable and critical medical consumable in the medical industry, the efficient assembly of anesthesia tubes is of paramount importance. This project focuses on a key aspect of automated anesthesia tube assembly equipment—automated airtightness testing of the assembled anesthesia tubes.

[0004] Current anesthetic tube airtightness testing devices on the market have certain shortcomings: most existing testing equipment is manual, requiring manual operation. Workers need to load and position the anesthetic tubes one by one before the testing process can be carried out. This working method reduces the overall production and testing efficiency. Furthermore, the manual testing method cannot be integrated into automated production lines for online use, resulting in low testing efficiency and low continuity. Therefore, it is necessary to design an automated airtightness testing device for anesthetic tubes that can automatically load and test their airtightness. Utility Model Content

[0005] To overcome the shortcomings of existing technologies where most testing equipment is manual and requires manual operation, workers need to load and position the anesthesia tubes one by one before the testing process can be carried out. This working method reduces the overall production and testing efficiency. Furthermore, the manual testing method cannot be integrated into automated production lines for online use, resulting in low testing efficiency and low continuity. One of the purposes of this utility model is to provide an automated airtightness testing device for flexible tubes.

[0006] One of the objectives of this utility model is achieved through the following technical solution: an automated hose airtightness testing device, comprising a clamping mechanism one, a clamping mechanism two, a feeding mechanism, and a hose test piece: the feeding mechanism includes a four-axis robotic arm and a clamping assembly mounted on the four-axis robotic arm. The clamping assembly consists of a support base mounted on one side of the four-axis robotic arm and two sets of pneumatic grippers symmetrically mounted on one side of the support base. The two sets of pneumatic grippers are mounted at right angles on the support base. The pneumatic grippers are used to feed the hose test piece, and one end of the hose test piece is equipped with a connector; the clamping mechanism one includes a base plate and a clamping mechanism mounted on the support base. The system comprises a base plate 1, a telescopic cylinder 1 mounted on the base plate 1, a connecting block mounted on the output end of the telescopic cylinder 1, a connecting pipe mounted on one side of the connecting block, a base plate 2 mounted on the base plate 1, and a pneumatic gripper 2 mounted on the base plate 2. The connecting pipe is assembled with the connecting component. The clamping mechanism 2 includes a base plate 2 located on one side of the base plate 1, a mounting base 1 mounted on the base plate 2, a telescopic cylinder 2 mounted on the mounting base 1, a connecting pipe symmetrically mounted on one side of the telescopic cylinder 2, a mounting base 2 mounted on the base plate 2, and a pneumatic gripper 3 mounted on the mounting base 2. With the cooperation of the feeding mechanism, clamping mechanism 1, and clamping mechanism 2, automated feeding and automated positioning detection of hose test pieces can be achieved, reducing the labor intensity of workers and significantly improving detection efficiency.

[0007] According to the aforementioned automated airtightness testing device for hoses, an airtightness testing instrument body is provided on one side of the clamping mechanism, and an air supply channel is provided on the connecting block. The air supply channel, the connecting pipe, and the connecting piece are interconnected, and the air supply channel is connected to the airtightness testing instrument body through a pipe.

[0008] According to the aforementioned automated hose airtightness testing device, one of the pneumatic grippers has an arc-shaped clamping groove, and the inner wall of the arc-shaped clamping groove is provided with anti-slip texture. The anti-slip texture plays a role in preventing slippage, thereby improving the clamping stability of the hose test piece.

[0009] According to the aforementioned automated hose airtightness testing device, the connecting member is tapered, and the size of one end of the connecting member is adapted to the inner diameter of the connecting member. This achieves a sealed connection, facilitating airtightness testing of the hose test specimen.

[0010] According to the aforementioned automated hose airtightness testing device, the size of the connecting pipe is adapted to the inner diameter of the hose test piece, thereby achieving a sealed connection with the hose test piece.

[0011] According to the aforementioned automated hose airtightness testing device, force sensors are installed on one side of both the second and third pneumatic grippers. This facilitates the detection of the clamping force of the second pneumatic gripper on the hose test piece, preventing damage to the hose test piece due to excessive clamping force and displacement of the hose test piece due to insufficient clamping force, thus effectively ensuring clamping stability.

[0012] According to the aforementioned automated hose airtightness testing device, displacement sensors are installed on one side of both the first and second telescopic cylinders. This facilitates precise docking of the connecting pipes and connectors.

[0013] According to the aforementioned automated hose airtightness testing device, the airtightness testing instrument body, the first clamping mechanism, the second clamping mechanism, and the feeding mechanism are all communicatively connected to an external control system. This facilitates online and automated control.

[0014] The above-mentioned solution has the following beneficial effects:

[0015] With the addition of a feeding mechanism, clamping mechanism one, and clamping mechanism two, this device can automatically feed hose test pieces and automatically detect their airtightness, compared to the existing method that requires manual feeding of each hose test piece for testing. This effectively improves testing efficiency. Furthermore, this device can be installed on automated production lines to achieve continuous production and testing, thereby enhancing its practicality and convenience.

An air tightness tester body 6 is located on one side of the clamping mechanism 1. An air supply channel 7 is provided on the connecting block 104. The air supply channel 7, the connecting pipe 105, and the connector 5 are interconnected. The air supply channel 7 is connected to the air tightness tester body 6 via a pipe. An arc-shaped clamping groove is provided on the pneumatic gripper 322. 8. The inner wall of the arc-shaped clamping groove 8 is provided with anti-slip texture 9. The connecting pipe 105 is conical. The size of one end of the connecting pipe 105 is adapted to the inner diameter of the connector 5. The size of the connecting pipe 24 is adapted to the inner diameter of the hose test piece 4. Force sensors 10 are installed on one side of the pneumatic gripper 2 107 and the pneumatic gripper 3 26. Displacement sensors 11 are installed on one side of the telescopic cylinder 1 103 and the telescopic cylinder 2 23.

[0029] See Figure 3 , Figure 3This is an overall view of the assembled hose test piece 4 and connector 5. The hose test piece 4 is an anesthesia tube. The hose test piece 4 and connector 5 are automatically assembled and used as a whole for airtightness testing. The operation of the airtightness tester body 6, clamping mechanism 1, clamping mechanism 2 and feeding mechanism 3 can be controlled by an external control system. The operating status of the device can be monitored. By setting force sensor 10, the force of pneumatic gripper 2 107 and pneumatic gripper 3 26 in clamping the hose test piece 4 can be monitored.

It is easy to use and greatly reduces the labor intensity of workers.

[0030] Working principle: When an airtightness test is required on the hose test piece 4, the two sets of pneumatic grippers 322 on the clamp assembly 32 are used to grip the hose test piece 4 for loading. The movement trajectory of the clamp assembly 32 is controlled by the four-axis robotic arm 31. The clamp assembly 32 moves the hose test piece 4 to one side of the clamping mechanism 1 and clamping mechanism 2, so that the two openings on one side of the hose test piece 4 are connected to the connecting pipe 24 on the clamping mechanism 2. At this time, the connecting piece 5 is located in the pneumatic gripper 107 of the clamping mechanism 1. The pneumatic gripper 107 and pneumatic gripper 26 are activated to limit and fix the hose test piece 4 on the clamping mechanism 1 and clamping mechanism 2. The telescopic cylinder 103 is activated to drive the connecting pipe 105 to one side of the connecting piece 5 through the connecting block 104, so as to achieve a sealed connection between the connecting pipe 105 and the connecting piece 5. The air supply interface of the airtightness tester body 6 is connected to the air supply channel 7 through the pipeline. The body 6 inflates the hose test piece 4 with gas for testing. The gas enters the hose test piece 4 through the pipe, gas delivery channel 7, connecting block 104, connecting pipe 105, and connecting piece 5. The end of the hose test piece 4 connected to the connecting pipe 24 is empty. Since the upper platform of the telescopic cylinder 23 is closed, the end of the hose test piece 4 that is connected to the connecting pipe 24 is essentially sealed. Thus, the gas accumulates inside the hose test piece 4, and its airtightness is tested by the airtightness tester body 6. Compared with the existing method of manually feeding and testing each hose test piece 4 one by one, this device, with the cooperation of the feeding mechanism 3, clamping mechanism 1, and clamping mechanism 2, can automatically complete the feeding of the hose test piece 4 and automatically test the airtightness of the hose test piece 4, effectively improving the testing efficiency. At the same time, this device can be installed on an automated production line for use to achieve continuous production and testing, thereby improving the practicality and convenience of the device.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
