Description

Technical Field

[0001] The present invention relates to the technical field of automated detection equipment, and particularly to a soft bag intelligent lamp inspection machine. Background Art

[0002] Medical infusion soft bags are used to store liquid medicines. However, due to reasons such as production environment or production process, some tiny foreign matters with small particle sizes may be mixed into the infusion finished products, such as aluminum chips, glass chips, rubber chips, fibers or insoluble drug substances and other tiny foreign matters. During the process of intravenous infusion, these foreign matters may enter the human body along with the liquid, thus causing blood vessel blockage and seriously affecting the life and health of patients. Therefore, during the production process of infusion finished products, it is necessary to check the liquid medicines injected into each infusion soft bag for foreign matters one by one.

[0003] The current detection method is to check through manual vision. The inspector directly observes the liquid medicine in the infusion soft bag through the naked eye under certain lighting conditions to check whether there are foreign matters in the soft bag.

During operation, the four shaking mechanisms 33 are respectively located in the loading area, the shaking area, the photographing area, and the unloading area, and can perform operations in each stage synchronously, improving the work efficiency.

[0036] As Figure 1-2 , the feeding conveyor line 1 is provided with a synchronous belt 11, and equally spaced stoppers 111 are installed on the synchronous belt 11 to achieve the fixed-distance conveyance of the transparent soft bags 100. In addition, a bag mouth limiting member 112 is arranged on the synchronous belt 11 to limit the position of the bag mouth of the transparent soft bag 100, further defining the position of the transparent soft bag 100 and facilitating the accurate positioning and grasping of the loading mechanism 2.

[0037] As Figure 3-4, the feeding mechanism 2 includes a fixed frame 21, a swing frame 23, a rotary drive mechanism 22, a gripper 24 and a gripper cylinder 25; wherein, one end of the swing frame 23 is rotatably connected to the fixed frame 21, and the other end is connected to the gripper 24; the rotary drive mechanism 22 is installed on one side of the fixed frame 21 and drives the swing frame 23 to rotate; the gripper 24 is movably installed on the swing frame 23 and is provided with a plurality of suction cups 242 for adsorbing soft bags; the gripper cylinder 25 is installed on the swing frame 23 and is drivingly connected to the gripper 24. Using swing-type conveying, multiple transparent soft bags 100 can be grabbed from the production line at the same time, with higher transportation efficiency compared to traditional manipulators.

[0038] The swing frame 23 includes a cylinder mounting plate 231 and two cylinder support plates 233; the cylinder mounting plate 231 is connected to the gripper 24, and the gripper cylinder 25 is installed on the side of the cylinder mounting plate 231 away from the gripper 24; the two cylinder support plates 233 are symmetrically arranged and perpendicular to the cylinder mounting plate 231, and both ends of each cylinder support plate 233 are respectively connected to the cylinder mounting plate 231 and the fixed frame 21; both ends of each cylinder support plate 233 are respectively connected to the cylinder mounting plate 231 and the fixed frame 21, and the rotary drive mechanism 22 is connected to one of the cylinder support plates 233. Setting two cylinder support plates 233 to connect the cylinder mounting plate 231 is beneficial to the structural stability. The gripper cylinder 25 is arranged between the two cylinder support plates 233, which is beneficial to reducing the occupied space.

[0039] The gripper 24 includes a suction cup mounting plate 241. The side of the suction cup mounting plate 241 close to the cylinder mounting plate 231 is connected to the gripper cylinder 25. The suction cup mounting plate 241 is provided with a plurality of grasping areas arranged at intervals, and each grasping area is provided with a plurality of suction cups 242.

The fixing frame 21 further includes a pair of fixing columns 211 arranged at intervals, the fixing columns 211 are located between the loading position and the feeding conveyor line 1, and the top end of each fixing column 211 is mounted with an extension plate 212 extending horizontally towards the feeding conveyor line 1, and the front end of each extension plate 212 is fixed to one end of the connecting plate 213.

[0043] The flipping mounting frame 214 is mounted with a first flipping limit block 2142 for stopping the excessive upward swing of the swinging frame 23 and a second flipping limit block 2141 for stopping the excessive downward swing of the swinging frame 23. In this embodiment, the moving range of the swinging frame 23 is 90 degrees. When grasping the transparent soft bag 100 from the feeding conveyor line 1, the swinging frame 23 swings downward, and the suction cup 242 sucks the soft bag. At this time, the soft bag is in a horizontal state, and then the swinging frame 23 swings upward to move the soft bag to the loading area, and the soft bag is converted from a horizontal state to a vertical state. In addition, a soft rubber structure is provided on the flipping limit block, which can play a role in buffering and protection.

[0044] Such as Figure 5-6 , the rotating bracket 34 includes a central rotating shaft 341 and a turntable 342, and the central rotating shaft 341 is rotatably mounted on the base 35, and the turntable 342 is fixedly arranged at the top end of the central rotating shaft 341.

[0045] Such as Figure 5-8As shown, the swinging mechanism 33 includes a mounting bracket 331, a first clamping device 332 and a second clamping device 333 which are arranged oppositely up and down.

Among them, the fixture 30 bearing seat is installed on the outer wall of the bushing 10 through a second bearing 420; the fixing block 440 is installed on the jaw bearing seat 470, and the two mounting plates 450 are respectively installed on both sides of the fixing block 440 and extend upward. The connector 50 is located between the mounting plates 450, and the two ends of the two fixed shafts 410 are respectively connected to the corresponding mounting plates 450.

[0052] The fixture mounting seat 40 further includes a lifting buffer pad 460. The lifting buffer pad 460 is installed on the upper side of the fixing block 440 and is provided with a through hole for the push rod 20 to pass through. During clamping, the connector 50 descends. The lifting buffer pad 460 abuts between the connector 50 and the fixing block 440 to play a buffering role.

[0053] The second jaw 3331 further includes a jaw backing plate 710 which is installed between the fixture 30 and the transparent clamping block 70. The jaw backing plate 710 is provided with a clamping groove matching the jaw, which is convenient for installation and positioning.

[0054] The second jaw 3331 further includes a second external gear 60. The second external gear 60 is sleeved on the jaw bearing seat 470. The set gear can cooperate with an external driving mechanism, thereby realizing the rotation of the fixture mounting seat 40. During detection, the fixture mounting seat 40 can be driven to rotate to shake the liquid in the transparent flexible bag, so that foreign objects move in the liquid.

[0055] Furthermore, the second jaw 3331 further includes a waterproof cover 430. The waterproof cover 430 covers the jaw bearing seat 470 from top to bottom, which is beneficial to protecting internal components.

[0056] Such as Figure 3-4 , the photographing mechanism 31 includes a camera bracket 312 and a plurality of cameras 311 installed on the camera bracket 312. The number of cameras 311 corresponds to the number of flexible bags clamped by each shaking mechanism 33. When the shaking mechanism 33 rotates to the photographing area, the first jaw 3323 and the second jaw 3331 stop rotating. The liquid in the transparent flexible bag 100 still continues to rotate under the action of inertia and is in a shaking state. At this time, the cameras 311 take multiple images of the transparent flexible bag 100 at different time points and transmit the captured images to the data processing and control unit. If there are foreign objects in the liquid, the foreign objects will change their positions with the shaking of the liquid. Therefore, if the positions of the shadows on the images at different time points change, it can be determined that the shadow is a foreign object existing in the liquid.

[0057] The lamp inspection mechanism 3 further includes a light source 32. The light source 32 is located on the side of the photographing area away from the photographing mechanism 31. Arranging the light source 32 is beneficial to improving the photographing effect.

[0058] Furthermore, such as Figure 1-2 , the present invention further includes an electric control box 6 and a machine table 7. The data processing and control unit, including an industrial computer, a driver, corresponding wires, wire grooves, etc. are all arranged in the electric control box 6; the machine table 7 is used for supporting. The feeding mechanism 2, the lamp inspection mechanism 3, and the discharging mechanism 4 are all installed on the machine table 7. The feeding conveyor line and the discharging conveyor line are arranged on the side of the machine table 7. There are also some standard connectors, adapters, fasteners, etc. commonly used in the field, which will not be elaborated here.

[0059] The operation mode of the flexible bag intelligent lamp inspection machine is as follows:

[0060] 1. Place the transparent flexible bag 100 to be tested on the feeding conveyor line 1, and the feeding conveyor line 1 sends the transparent flexible bag 100 to the outside of the feeding mechanism 2;

[0061] 2. The gripper of the feeding mechanism 2 descends to grasp the corresponding transparent flexible bag 100, and the rotary drive mechanism 22 drives the gripper to swing upward, sending the transparent flexible bag 100 to the feeding area;

[0062] 3. The swinging mechanism in the feeding area clamps the upper and lower ends of the transparent flexible bag 100 through the first clamping device and the second clamping device respectively, and the gripper of the feeding mechanism 2 releases the transparent flexible bag 100;

[0063] 4. The rotating bracket drives the swinging mechanism to revolve (taking Figure 4 as an example, the swinging mechanism rotates counterclockwise around the central rotating shaft), and at the same time, the first clamping jaw and the second clamping jaw drive the transparent flexible bag 100 to make reciprocating self-rotation movements;

[0064] 5. When the swinging mechanism rotates to reach the shooting area, the first clamping jaw and the second clamping jaw stop rotating, and the liquid in the transparent flexible bag 100 continues to rotate due to inertia and is in a shaking state. At this time, the camera 311 takes multiple images of the transparent flexible bag 100 at different time points and transmits the captured images to the data processing and control unit. If there is a foreign object in the liquid, the foreign object will change its position as the liquid shakes. Therefore, if the position of the shadow on the images at different time points changes, it can be determined that the shadow is a foreign object existing in the liquid;

[0065] 6. After the shooting is completed, the rotating bracket continues to rotate, and the swinging mechanism moves to the discharging area. The discharging mechanism 4 transfers the inspected transparent flexible bag 100 to the discharging conveyor line 5, ending the foreign object detection process.

[0066] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
