[0027] like Figure 1As shown, a finished product inspection device for medical sterilization bags comprises an inspection platform 1, on which a conveyor belt 3 is arranged, on which a plurality of inspection zones are arranged at equal intervals, on which a clamping member for clamping the sterilization bag is arranged, wherein the clamping member is a suction cup, and the suction cup is connected to a suction pump through a suction pipe, and a connecting frame 2 connected to the inspection platform 1 is arranged at the rear side of the conveyor belt 3, and a lifting assembly is arranged on the connecting frame 2, wherein the lifting assembly comprises a driving member and a lifting plate 10, wherein the driving member is used to control the lifting and moving of the lifting plate 10, and a holding block 11 is connected to the lower end of the lifting plate 10, and an air outlet 34 extending into the sterilization bag is arranged below the holding block 11, and the lower end surface of the holding block 11 A receiving groove 26 is provided to cooperate with the air outlet head 34, a moving rack 19 is fixed to one side of the lifting plate 10, a rotating gear 20 is meshed and transmitted on one side of the moving rack 19, the rotating gear 20 is coaxially connected with a first bevel gear 21, a second bevel gear 22 is meshed and connected to the front left side of the first bevel gear 21, the second bevel gear 22 is coaxially connected with a transmission shaft 36, a rotating shaft 23 transmission-connected to the transmission shaft 36 is provided on the front side of the conveyor belt 3, an air compression plate 24 is fixedly connected to the side wall of the rotating shaft 23, an infrared detector 27 is provided above the conveyor belt 3, and the light beam of the infrared detector 27 is horizontally arranged and parallel to the transmission direction of the conveyor belt 3.

[0028] The sterilization bag to be tested is placed on the conveyor belt 3 for transportation. The clamping part clamps the sterilization bag, and the suction pump is started to facilitate the suction cup to adsorb and clamp the sterilization bag Venus on the conveyor belt 3. When the sterilization bag moves to the bottom of the holding block 11, the air outlet head 34 extends into the sterilization bag from the opening of the sterilization bag, and the driving part controls the holding block 11 to hold the opening of the sterilization bag. The air outlet head 34 releases air to expand the sterilization bag. After the sterilization bag expands to a certain height, the infrared detector 27 detects the expanded sterilization bag. At this time, the driving part controls the holding block 11 to hold the opening of the sterilization bag. The holding block 11 and the lifting plate 10 move upward, and the holding block 11 relaxes the opening of the sterilization bag, so that the air in the sterilization bag can be discharged through the opening of the sterilization bag. When the lifting plate 10 rises, the rotating gear 20 is driven counterclockwise by the moving rack 19. Since the first bevel gear 21 is meshed with the second bevel gear 22, the second bevel gear 22 and the transmission shaft 36 are driven to rotate clockwise, and then the rotating shaft 23 is driven to rotate clockwise, so that the air pressure plate 24 exhausts the expanded sterilization bag, thereby improving the detection efficiency of the sterilization bag.

[0029] A support rod is arranged between the rotating shaft 23 and the conveyor belt 3, and a limiting protrusion is arranged on the lower end surface of the air pressure plate 24 to cooperate with the support rod. After the rotating shaft 23 rotates clockwise to drive the air pressure plate 24 to press the expanded sterilization bag forward, the air pressure plate 24 and the conveyor belt 3 are not in contact with each other, and the unexpanded sterilization bag can come between the air pressure plate 24 and the conveyor belt 3.

[0030] A first pressure switch 25 is provided directly below the holding block 11 and is located below the conveyor belt 3. The normally open contact of the first pressure switch 25 is connected to the infrared detector 27. When the holding block 11 holds the sterilization bag, the first pressure switch 25 detects the holding and is in a closed state. At this time, the infrared detector 27 is opened to detect the expansion degree of the sterilization bag.

[0031] In order to limit the lifting plate 10 to move only up and down, a vertical block 9 is provided on the front end face of the connecting frame 2, and a strip groove 8 is provided on the lifting plate 10 to cooperate with the vertical block 9. The lower end of the vertical block 9 is connected to the lower end of the strip groove 8 through a connecting spring. The connecting spring increases the pressure of the holding block 11 to hold the sterilization bag, which facilitates better holding of the sterilization bag.

[0032] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the driving member includes a driving motor 4 connected to the connecting frame 2, the output end of the driving motor 4 is connected to a driving shaft 5, a first connecting rod 6 and a second connecting rod 7 located in the counterclockwise direction of the first connecting rod 6 are arranged on the outer side wall of the driving shaft 5, the second connecting rod 7 is located at the oblique front side of the first connecting rod 6, the length of the second connecting rod 7 is greater than the length of the first connecting rod 6, a lifting block 12 matched with the second connecting rod 7 is arranged on the upper left side of the lifting plate 10, a hinge shaft 15 connected to the connecting frame 2 is arranged on the lower left side of the lifting plate 10, a torsion spring is arranged on the hinge shaft 15, a toggle rod 16 and a sub-block 13 located in the clockwise direction of the toggle rod 16 are arranged on the side wall of the hinge shaft 15, the toggle rod 16 is arranged in cooperation with the first connecting rod 6, a mother block 14 matched with the sub-block 13 is arranged on the lifting plate 10, a limiting block 17 is arranged on the left side of the lifting plate 10, and a spring matched with the limiting block 17 is arranged below the limiting block 17 The limiting block 17 cooperates with the limiting rod 18, and the limiting rod 18 is connected to the connecting frame 2. When the sterilization bag under the holding block 11 needs to be inspected and processed, the holding block 11 is located above the opening of the sterilization bag, and the driving motor 4 is started to drive the driving shaft 5 to rotate clockwise. The first connecting rod 6 contacts the toggle rod 16 and drives it to rotate counterclockwise, and the sub-card block 13 swings counterclockwise to move the mother card block 14 to the bottom thereof, and the lifting plate 10 and the holding block 11 move downward. At this time, the limiting block 17 moves downward. The end contacts the limiting rod 18. In order to prevent the air outlet head 34 from being crushed by the holding block 11, the holding block 11 clamps the opening of the sterilization bag, and the air outlet head 34 inflates the sterilization bag. After a period of time, the infrared detector 27 detects that the sterilization bag has expanded to a certain size. At this time, the second connecting rod 7 contacts the lifting block 12, and the second connecting rod 7 rotates to drive the lifting block 12 to move upward, so that the lifting plate 10 and the holding block 11 move upward, and then the mother card block 14 moves to the upper end of the sub-card block 13 and engages with it.

[0033] like Figure 3 , Figure 4 and Figure 5As shown, in order to facilitate the air to enter the sterilization bag through the air outlet head 34 for inflation when the holding block 11 presses the opening of the sterilization bag, and when the holding block 11 relaxes the opening of the sterilization bag, part of the air in the sterilization bag can be discharged through the air outlet head 34, an eccentric shaft 32 is arranged on the second connecting rod 7, and an air cylinder 28 is arranged below the second connecting rod 7. A piston 29 is arranged in the air cylinder 28 for moving up and down. The upper end of the piston 29 is connected to a moving rod 30 that passes through the air cylinder 28. The upper end of the moving rod 30 is hinged to the eccentric shaft 32 through a driving arm 31, and the lower end of the air cylinder 28 is connected to the air outlet head 34 through an air outlet pipe 33. When the driving shaft 5 rotates, the moving rod 30 is driven to move up and down by the driving arm 31, so that The piston 29 moves up and down in the air cylinder 28. When the holding block 11 holds the opening of the sterilization bag, the eccentric shaft 32 moves downward driven by the second connecting rod 7, and the piston 29 moves downward in the air cylinder 28. The air in the air cylinder 28 is input into the sterilization bag through the air outlet head 34 for expansion. After expansion to a certain extent, the infrared detector 27 also detects the expanded sterilization bag. The driving shaft 5 is still rotating, driving the piston 29 to move upward in the air cylinder 28, so as to start discharging the air in the sterilization bag. The second connecting rod 7 is cooperated with the lifting block 12. The second connecting rod 7 lifts the lifting block 12 and the lifting plate 10 upward. When the holding block 11 relaxes the opening of the sterilization bag, part of the air in the sterilization bag can also be discharged through the air outlet head 34.

[0034] In order to further sterilize the sterilization bag, a plurality of ultraviolet lamps are provided on the inner side walls of the air pressure plate 24 and the air cylinder 28 .

[0035] like Figure 1 and Figure 2 As shown, in order to extend the air outlet head 34 into and out of the sterilization bag, a driving telescopic push rod 35 located on one side of the conveyor belt 3 is provided on the detection table 1, and the telescopic end of the driving telescopic push rod 35 is connected to the air outlet head 34.

[0036] In order to prevent the air intake of the air outlet head 34 from being affected when the holding block 11 holds the opening of the sterilization bag, and to prevent the air in the sterilization bag from flowing out through the gap between the receiving groove 26 and the air outlet head 34 when the air outlet head 34 is inflating the sterilization bag, an arc-shaped push plate is connected to the top of the receiving groove 26 through an elastic member, and elastic sealing members are provided on the front and rear sides of the elastic member, the elastic member is a pushing spring, and the elastic sealing member is a rubber pad, so that when the holding block 11 holds the opening and the air outlet head 34 of the sterilization bag, the air in the sterilization bag is not easy to flow out through the gap between the receiving groove 26 and the air outlet head 34, thereby improving the sealing performance.

[0037] Based on the above embodiment, a detection method of a finished product detection device for medical sterilization bags is proposed, comprising the following steps: placing the sterilization bag to be detected on a conveyor belt 3 for transportation, when the sterilization bag moves to the bottom of the holding block 11, the air outlet head 34 extends from the opening of the sterilization bag into the sterilization bag, the driving component controls the holding block 11 to hold the opening of the sterilization bag, and the air outlet head 34 discharges air to expand the sterilization bag. After the sterilization bag expands to a certain height, the infrared detector 27 detects the expanded sterilization bag. At this time, the driving component controls the holding block 11 and the lifting plate 10 to move upward, and the air in the sterilization bag is discharged through the opening of the sterilization bag. When the lifting plate 10 rises, the rotating gear 20 is driven to rotate counterclockwise by the moving rack 19. Due to the meshing transmission of the first bevel gear 21 and the second bevel gear 22, the second bevel gear 22 and the transmission shaft 36 are driven to rotate clockwise, and then the rotating shaft 23 is driven to rotate clockwise, so that the air pressure plate 24 exhausts the expanded sterilization bag, thereby improving the detection efficiency of the sterilization bag.

8. A detection method of the medical sterilization bag finished product detection device according to claim 1, characterized in that: The sterilization bag to be inspected is placed on a conveyor belt (3) for transportation. When the sterilization bag moves to the bottom of the holding block (11), the air outlet head (34) extends from the opening of the sterilization bag into the sterilization bag. The driving component controls the holding block (11) to hold the opening of the sterilization bag. The air outlet head (34) discharges air to expand the sterilization bag. After the sterilization bag expands to a certain height, the infrared detector (27) detects the expanded sterilization bag. At this time, the driving component controls the holding block (11) and the lifting plate (10) to move upward. The air in the sterilization bag is discharged through the opening of the sterilization bag. When the lifting plate (10) rises, the rotating gear (20) is driven to rotate counterclockwise by the moving rack (19). Due to the meshing transmission of the first bevel gear (21) and the second bevel gear (22), the second bevel gear (22) and the transmission shaft (36) are driven to rotate clockwise, thereby driving the rotating shaft (23) to rotate clockwise, so that the air pressure plate (24) performs exhaust treatment on the expanded sterilization bag, thereby improving the detection efficiency of the sterilization bag.
