[0027] The embodiment of the present application provides a kind of automatic leak detection of flat soft bag lamp inspection integrated machine, including ascending electric inspection conveyor belt 1, horizontal electric inspection conveyor belt 2 and descending lamp inspection conveyor belt connected in sequence, the first end and the end of conveyor belt are defined according to the transmission direction of each conveyor belt, material placed on conveyor belt is transported from first end to end, so the above three conveyor belts are used to convey soft bag 19 to be inspected from first end to end, ascending electric inspection conveyor belt 1 is inclined upward from first end to end, i.e. the end of ascending electric inspection conveyor belt 1 is higher than first end, horizontal electric inspection conveyor belt 2 is in horizontal state, i.e. the first end and the end of horizontal electric inspection conveyor belt 2 are flush, descending lamp inspection conveyor belt is inclined downward from first end to end, i.e. the first end of descending lamp inspection conveyor belt is higher than end.Further, the end of ascending electric inspection conveyor belt 1 is connected to the first end of horizontal electric inspection conveyor belt 2, and the end of horizontal electric inspection conveyor belt 2 is connected to the first end of descending lamp inspection conveyor belt, i.e. the three conveyor belts form an arch structure.A plurality of soft bags 19 to be inspected are placed on each conveyor belt in turn, with the mouth tube of the soft bag 19 facing backward, and the bag tail of the soft bag 19 facing forward, according to the advancing direction of the soft bag 19 to be inspected, the front and rear directions are defined, the direction of the soft bag 19 to be inspected moving forward is the front, and the opposite direction is the rear, and when the soft bag 19 to be inspected is placed on a single conveyor belt, the end of the soft bag 19 to be inspected close to the end of the conveyor belt is the front end and is the bag tail structure, and the end of the soft bag 19 to be inspected close to the first end of the conveyor belt is the rear end and has a mouth tube structure.A high-voltage discharge leak detection device is provided above the ascending electric inspection conveyor belt 1 and the horizontal electric inspection conveyor belt 2, and a visual lamp inspection device is provided above the descending lamp inspection conveyor belt.

[0028] During operation, the soft bag 19 to be inspected is continuously placed flat on each conveyor belt, and is transported from the first end to the end by each conveyor, so that the soft bag 19 to be inspected is in a flat state and sequentially passes through the high-voltage discharge leak detection device and the visual lamp inspection device, and then high-voltage discharge leak detection and visual lamp inspection are performed, the presence of impurities and particles in the liquid in the bag is detected by visual lamp inspection, and the presence of slight damage, leakage or micro-permeation of the bag body is detected by high-voltage discharge, without the need to change to a vertical state, effectively improving the overall operation efficiency, without the need for external forces such as knocking on the soft bag 19 to be inspected to change the position of foreign matter in the bag, without the need for other components to come into contact, avoiding false detection caused by secondary contamination, and improving the reliability of the equipment.

[0029] Please refer to Figure 2 , Figure 2 The structure diagram of the electric inspection part in one embodiment of the flat soft bag automatic lamp inspection leak detection integrated machine provided by the present application.

[0030] Specifically, the high-voltage discharge leak detection device comprises a first side edge electric detection device 3, a mouth tube electric detection device 4, a second side edge electric detection device 5, a bag body electric detection device 6 and a bag tail electric detection device 7, the first side edge electric detection device 3, the mouth tube electric detection device 4, the second side edge electric detection device 5 and the bag body electric detection device 6 are arranged in sequence from the head end to the tail end above the ascending electric detection conveying belt 1, and the bag tail electric detection device 7 is arranged above the horizontal electric detection conveying belt 2.

[0031] Due to the inclination direction of the ascending electric detection conveying belt 1 and the arrangement mode of the soft bag 19 to be detected, when the ascending electric detection conveying belt 1 climbs, the mouth tube faces backward, at this time, the liquid medicine completely fills the inner cavity of the mouth tube and the two sides of the bag body, and only part of the air is in the bag tail part, at this time, the detection effect of the high-voltage discharge leak detection of the mouth tube combined cover, the bag body and the two sides is the best, and the precision is the highest, and when the bag body is horizontal on the horizontal electric detection conveying belt 2, the liquid medicine fills the bag tail, the air in the bag runs to the upper surface, and the detection effect of the high-voltage discharge leak detection of the bag tail is the best, and the precision is the highest.

[0032] Please refer to Figure 3 , Figure 3 The structure diagram of the lamp detection part in one specific embodiment of the flat-lying type soft bag automatic lamp detection and leak detection integrated machine provided by the application.

[0033] Further, the descending lamp detection conveying belt comprises a first lamp detection conveying belt 8 and a second lamp detection conveying belt 9 which are connected in sequence from the head end to the tail end, and the visual lamp detection device comprises a first lamp detection device 10 located above the first lamp detection conveying belt 8 and a second lamp detection device 11 located above the second lamp detection conveying belt 9, and the first lamp detection conveying belt 8 and the second lamp detection conveying belt 9 are used for providing different background colors. Due to the inclination direction of the descending lamp detection conveying belt and the arrangement mode of the soft bag 19 to be detected, when the descending lamp detection conveying belt descends, the bag tail faces forward and is in a low position, and the mouth tube faces backward and is in a high position, at this time, the liquid medicine in the mouth tube flows into the transparent bag body for lamp detection, avoiding the liquid medicine remaining in the mouth tube, preventing foreign matters from remaining in the mouth tube part, and ensuring the safety and reliability of lamp detection.

[0034] Specifically, the belt of the first lamp inspection conveying belt 8 is a black PU belt, and the belt of the second lamp inspection conveying belt 9 is a white PU belt. When the descending lamp inspection conveying belt descends, the bag tail is in a low position and the mouth tube is in a high position, and at this time, the inner cavity of the mouth tube is free of liquid, so that the liquid in the bag can be detected without dead angle, and the black and white background contrast imaging can effectively detect the foreign matter in the bag. The black PU and white PU two-section belt conveyors are adopted, which not only realize the conveying of product materials, but also provide black and white backgrounds for the visual lamp inspection detection to realize contrast imaging. The black PU and white PU belt conveyors adopt a belt quick-change structure, and the worn and contaminated belts can be cleaned or replaced regularly, which is convenient and fast, ensures the visual lamp inspection detection effect and quality, and can also set more lamp inspection devices according to needs.

Specifically, the electric inspection rejection device 12 and the lamp inspection rejection device 13 each include a movable conveying belt and a lifting mechanism, and the lifting mechanism is used to drive the start of the movable conveying belt to swing up and down. When the soft bag is qualified, the movable conveying belt is aligned with the horizontal electric inspection conveying belt 2 and the descending lamp inspection conveying belt, and the soft bag is normally transported to the movable conveying belt, and the qualified soft bag is conveyed to the next process through the movable conveying belt. When the soft bag is unqualified, the corresponding lifting mechanism is started to lift the corresponding movable conveying belt, and the unqualified soft bag falls, and then the lifting mechanism is reset to reset the corresponding movable conveying belt.

[0036] Please refer to Figure 4 , Figure 4 is a top view schematic diagram of one specific embodiment of the flat-lying soft bag automatic lamp inspection and leakage detection all-in-one machine provided by the present application.

On the other hand, when the equipment fails, temporary low-speed manual detection can be performed, and the qualified products can also be sampled for inspection, which increases the reliability and practicality of the whole system.

[0038] In order to improve the stable layout of the equipment, the frame assembly 16 is further included, and the ascending electric detection conveying belt 1, the horizontal electric detection conveying belt 2, the descending light detection conveying belt, the high-voltage discharge leak detection device and the visual light detection device are fixedly installed on the frame assembly 16. The frame assembly 16 is provided with the rejection collection conveying belt 17 on one side, and the electrical box 18 is provided on the other side of the frame assembly 16.

[0039] The specific detection process is as follows: the soft bag large infusion product after terminal sterilization is conveyed to the input conveying belt 15 according to the arrangement mode of printing facing down, bag tail facing forward and port tube facing backward, the interval of each soft bag 19 to be detected is pulled open through the input conveying belt 15, and then enters the inside of the equipment. In the climbing section of the ascending electric detection conveying belt 1, the staggered round belt conveying is adopted to detect the left and right side sealing edges of the bag body, the port tube and the upper and lower part of the bag body, and then conveyed to the horizontal electric detection conveying belt 2 to detect the bag tail. After the overall sealing detection is completed, the qualified products enter the next station, and the unqualified products are rejected and conveyed to the corresponding collection box through the rejection collection.
