Description

Technical Field

[0001] The utility model relates to an automatic leakage detection production line for medical hoses, belonging to the technical field of quality detection of infusion tubes. Background Art

[0002] A single medical hose consists of a main line and multiple branches, and is equipped with a variety of accessories. Usually, the accessories are equipped with sealing end caps, and the pipes are connected by injecting glue at both ends of the accessories. If the glue injection quality is poor, the medical hose will have poor leakage due to insufficient tightening force of the end cap and poor glue injection.

[0003] In order to avoid air leakage, the existing technology usually chooses to set up a leak detection station on the production line. One person is responsible for one leak detection machine. The medical hose is manually grabbed to the leak detection machine for leak detection. After the leak detection is completed, qualified products are manually put back into the production line, and unqualified products are manually removed from the production line. Based on the above operation process, the leak detection time of a single medical hose includes: loading time + leak detection time (constant) + unloading time. If the annual production requirement is to be met, multiple manual leak detection machines need to be placed, which will undoubtedly increase the labor input. If the number of leak detection machines is reduced, the manual loading and unloading time needs to be reduced, which will increase the workload of the personnel, and errors will occur in the loading and unloading processes, leading to problems such as missed detection and false detection. Utility Model Content

[0004] In order to solve the above problems, the utility model provides an automatic leak detection production line for medical hoses, which perfectly combines an automatic leak detector and a transmission line to reduce labor input and improve the leak detection efficiency of products.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A medical hose automatic leak detection production line comprises a left elevator, a right elevator and a transmission line between the left elevator and the right elevator, a tray is placed on the transmission line, and the transmission line further comprises an upper transmission line and a lower transmission line, wherein the tray placed on the upper transmission line is used to carry the medical hose that has been coiled and is waiting for detection, and the tray placed on the lower transmission line is empty and waiting to carry the medical hose; a plurality of leak detection stations are arranged along the upper transmission line, an automatic leak detection machine is correspondingly arranged above each leak detection station, and a lifting and positioning mechanism is correspondingly arranged below each leak detection station, the lifting and positioning mechanism is straddled above the transmission line, and is used to lift the tray carrying the medical hose so that the two ends of the medical hose are connected to the detection interface of the automatic leak detection machine.

[0007] Preferably, the lifting and positioning mechanism includes positioning pin mounting plates arranged on both sides of the transmission line, and positioning pins are respectively provided on the inner edges of each positioning pin mounting plate, and the positioning pins are used to align and socket with the positioning sleeves provided on the pallet; the positioning pin mounting plates are drivingly connected to the vertically arranged lifting cylinders, and under the action of the lifting cylinders, the positioning pin mounting plates drive the pallet to move up and down.

[0008] Preferably, the tray comprises a bearing plate and positioning sleeve fixing plates arranged at two outer edges of the bearing plate, and a positioning sleeve for being sleeved with a positioning pin is installed on each positioning sleeve fixing plate.

[0009] Preferably, a plurality of pipeline detection ventilation joint positioning plates are provided on the upper surface of the carrier plate and adjacent to one side edge, and two pipeline detection ventilation joints are provided on each pipeline detection ventilation joint positioning plate, one side of the pipeline detection ventilation joint is used to dock with the two ends of the medical hose, and the other side of the pipeline detection ventilation joint is used to dock with the detection joint of the automatic leak detector.

[0012] Preferably, a reader / writer is provided at each leak detection station, and correspondingly, a reader / writer card is attached to each tray, and the reader / writer identifies the information on the reader / writer card to determine whether the medical hose in the tray has been detected.

[0013] The beneficial effects of the utility model are as follows: the pallet is transmitted from the main transmission line to the bottom of the automatic leak detector, the lifting and positioning mechanism lifts the pallet to the detection position, the automatic leak detector docks with the two pipeline detection and ventilation joints on the pallet bearing plate and starts detection, while freeing up transmission space for pallets that need to be detected later or have been detected. After the detection is completed, the lifting and positioning mechanism is responsible for putting the pallet back on the transmission line and transmitting it to the unloading station where the detected hose can be unloaded manually or by a robot. The empty pallet is lowered by the right hoist to the bottom of the transmission line and transmitted to the left hoist. The left hoist lifts the empty pallet to the top of the transmission line to provide a bearing pallet for loading. This production line can completely replace manual labor and realize the automation of medical hose leak detection.

[0014] The leak detection production line of the utility model can match the rhythm of the leak detection station with the rhythm of the coil production line according to the rhythm requirements, and place it behind the coil station. It can not only prevent the problem of direct bagging of defective products such as leakage at the coil station, but also is set up relatively independently from the coil production line, preventing the failure of the leak detection station from causing the whole line to stop. At the same time, the whole line is equipped with multiple automatic leak detectors, each of which works continuously and uninterruptedly, thereby minimizing labor input and improving the efficiency of qualified leak detection.

A pallet 202 is placed on the transmission line 205. The transmission line 205 also includes an upper transmission line 101 and a lower transmission line 102.

The transmission speed of the lower transmission line 102 is greater than that of the upper transmission line 101. The empty pallet is transmitted to the left elevator 201, and the left elevator 201 lifts the empty pallet 203 to the upper transmission line 101 to provide a bearing pallet for loading.

[0028] Five leak detection stations are arranged along the transmission line 101, each of which is provided with a position sensor 104, and two adjacent leak detection stations are separated by a buffer stopper 103; each leak detection station is provided with a reader / writer 105, and correspondingly, a reader / writer card is attached to each tray 202.

[0029] Furthermore, an automatic leak detector 203 is correspondingly arranged above each leak detection station, and a lifting and positioning mechanism 204 is correspondingly arranged below each leak detection station. The lifting and positioning mechanism 204 is connected across the transmission line 205 and is used to lift the tray 202 carrying the medical hose so that the two ends of the medical hose can be connected to the detection interface of the automatic leak detector 203. When the lifting and positioning mechanism 204 carries the tray in the lifting position for detection, the upper transmission line 101 below it is unobstructed and can continue to transport the tray.

[0030] Furthermore, the lifting and positioning mechanism 204 includes positioning pin mounting plates 403 arranged on both sides of the transmission line 205, and positioning pins 404 are respectively provided on the inner edges of each positioning pin mounting plate 403, and the positioning pins 404 are used to align and socket with the positioning sleeves 2204 provided on the tray 202; the positioning pin mounting plates 403 are drivingly connected to the vertically arranged lifting cylinders 402, and under the action of the lifting cylinders 402, the positioning pin mounting plates 403 drive the tray 202 to move up and down.

[0031] Furthermore, the tray 202 includes a bearing plate 2201 and positioning sleeve fixing plates 2203 arranged at two outer edges of the bearing plate 2201 , and a positioning sleeve 2204 for sleeve engagement with a positioning pin 404 is installed on each positioning sleeve fixing plate 2203 .

[0032] Furthermore, a plurality of pipeline detection ventilation joint positioning plates 2202 are provided on the upper surface of the supporting plate 2201 and adjacent to one side edge, and two pipeline detection ventilation joints 2205 are provided on each pipeline detection ventilation joint positioning plate 2202, one side of the pipeline detection ventilation joint 2205 is used to dock with the two ends of the medical hose, and the other side of the pipeline detection ventilation joint 2205 is used to dock with the detection joint of the automatic leak detector 203.

[0033] Working process of this utility model:

[0034] On the transmission line 205, there is a loading station on the side adjacent to the left elevator 201, and there is an unloading station on the side adjacent to the right elevator 206. During the initial operation, the robot grabs the medical hose that has been coiled from the coil production line and installs it on the first tray 202. The first tray 202 moves on the transmission line 101 and is transferred to the bottom of the first automatic leak detector 203. When the first tray 202 passes through the first automatic leak detector 203, the reader 105 reads the information of the reader-writer card on the tray 202 to confirm whether the first tray has been tested. If not, The position sensor 104 senses and confirms that the first tray 202 has arrived at the leak detection station. At this time, the control system controls the lifting and positioning mechanism 204 to lift up, and the positioning pin 404 on the lifting and positioning mechanism 204 is inserted into the positioning bushing 2204 on the first tray 202, thereby lifting the first tray 202 to the detection position. The pipeline detection vent connector 2205 on the first tray 202 is connected to the detection connector of the first automatic leak detector 203, and the leak detection work of the medical hose on the first tray 202 is carried out. While the leak detection work of the medical hose on the first tray 202 is being carried out , the second tray 202 will pass under the first tray 202. Since the first automatic leak detector 203 is working, the control system controls the buffer stopper 103 to open and automatically release the second tray 202 to the bottom of the second automatic leak detector 203. Similarly, when the second tray 202 passes through the second automatic leak detector 203, the reader 105 reads the information of the reader-writer card on the tray 202 to confirm whether the second tray has been tested. If it has not been tested, the position sensor 104 senses and confirms that the second tray 202 has arrived at the leak detection station, and the buffer stopper 103 is used to open. The impact stopper 103 stops the second pallet 202 at the precise position below the second automatic leak detector 203. At this time, the control system controls the lifting and positioning mechanism 204 to lift, and the positioning pin 404 on the lifting and positioning mechanism 204 is inserted into the positioning sleeve 2204 on the second pallet 202, thereby lifting the second pallet 202 to the detection position, and the pipeline detection vent connector 2205 on the second pallet 202 is connected to the detection connector of the second automatic leak detector 203, and the second automatic leak detector 203 detects the medical hose on the second pallet 202, and so on.

[0035] Furthermore, the time for the robot to release the material at the loading station can be set so that the pallet 202 carrying the medical hose can enter the leak detection station uninterruptedly, and the five automatic leak detectors can achieve uninterrupted working status; when the first automatic leak detector 203 has completed the detection, the lifting and positioning mechanism 204 is responsible for lowering the first pallet 202 to the transmission line 205. At this time, the position sensor 104 senses whether there is a pallet on the first leak detection station. If there is, it is necessary to wait and give priority to other pallets that have completed the detection. If not, the control system triggers a lowering signal to control the lifting and positioning mechanism 204 to lower the detected pallet to the transmission line 205, and when it is transmitted to the unloading station via the transmission line 205, the unloading station reader reads the information on the reader-writer card to control the robot to sort and unload the product.

[0036] The leak detection production line provided by the utility model can set the number of automatic leak detection machines on the line body according to the annual production requirements. After the robot places the product on the pallet at the optimal rhythm, it can continuously enter the detection station for detection. Through the control system, as long as the robot completes the placement, the pallet carrying the product can continuously enter the line body to reach the leak detection station for detection. Except for the line body transmission time, no other unnecessary waiting time is required and the leak detection can be directly carried out. At the same time, a position sensor is installed and controlled by the system to avoid the lifting of the pallet and the collision of the transmission line pallet caused by sudden reasons, thereby ensuring safety.
