Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 6 As shown, this utility model provides a bottle cap tightness testing device for medical medicine bottles, including a ring conveyor belt 1, an identification frame 2 and an adjustment module, on which the bottle body 3 is conveyed;

[0026] It also includes a conveyor frame 15, an identification frame 2 fixedly connected to the conveyor frame 15, a microcontroller 16 installed on the conveyor frame 15, a sound and light alarm 17 installed on the identification frame 2, two conveyor rollers rotatably installed on the inner wall of the conveyor frame 15, both conveyor rollers are connected to the annular conveyor belt 1 for transmission, and a conveyor motor 9 is installed on the side of the conveyor frame 15, the output shaft end of the conveyor motor 9 is fixedly connected to a conveyor roller.

[0027] A bottle cap is threaded onto the main body 3 of the medicine bottle, and an identification sticker 20 is fixedly installed on the main body 3 of the medicine bottle;

[0028] By setting the label 20, it is easy to accurately and quickly limit the layout angle of the medicine bottle body 3 on the circular conveyor belt 1;

[0029] A set of regularly distributed trays 18 adapted to the medicine bottle body 3 are provided on the circular conveyor belt 1. Each tray 18 is provided with a set of rotating rods 19.

[0030] By setting the tray 18, the placement position of the medicine bottle body 3 on the annular conveyor belt 1 is limited. When the medicine bottle body 3 is placed on the annular conveyor belt 1, the orientation of the bottle cap should be uniform.

[0031] The distance adjustment module is equipped with an active clamp 4 and a driven clamp 5 respectively.

[0032] The pitch adjustment module includes a pitch adjustment screw 21 rotatably connected to the conveyor frame 15. A motor is mounted on the side of the conveyor frame 15. The output shaft of the motor is fixedly connected to the pitch adjustment screw 21. The pitch adjustment screw 21 is provided with a positive thread section and a negative thread section respectively. The active clamp 4 and the driven clamp 5 are respectively connected to the positive thread section and the negative thread section for transmission.

[0033] The distance between the active clamp 4 and the driven clamp 5 can be quickly adjusted by setting the distance adjustment module.

[0034] The inner wall of the active clamp 4 is sequentially equipped with an outer rotating disk 6, an inner rotating disk 7, and a force measuring disk 8, which rotate in sequence along the conveying direction of the annular conveyor belt 1. The outer rotating disk 6 is connected to the inner rotating disk 7 via a chain. The active clamp 4 is equipped with two motors 9, and the output shafts of the two motors 9 are respectively connected to the inner rotating disk 7 and the force measuring disk 8. A torque sensor 10 is provided at the connection between the force measuring disk 8 and the motor 9.

[0038] When the medicine bottle body 3 moves to the coaxial position with the inner rotating disk 7, the vision probe 11 performs visual recognition on the medicine bottle body 3. Through visual recognition, the angle of the label 20 relative to the vision probe 11 is detected. The microcontroller 16 adjusts the arrangement angle of the medicine bottle body 3 on the tray 18 through the inner rotating disk 7 and the driven disk 13 according to the visual recognition result of the vision probe 11, so that the label 20 on the medicine bottle body 3 is facing the vision probe 11.

The two dial indicators 12 are symmetrically arranged with the vertical plane containing the rotation axis of the outer disc 6 as the axis. The two dial indicators 12 correspond to the eccentric position of the outer disc 6.

[0041] Before the position of the medicine bottle body 3 is adjusted, the medicine bottle body 3 is pressed tightly between the universal steel ball 22 and the outer rotating plate 6, and the outer rotating plate 6 drives the medicine bottle body 3 to rotate at a set speed. The rotation of the bottle cap on the medicine bottle body 3 and the eccentric position setting of the two dial indicators 12 are used to monitor whether the bottle cap is misaligned or tightened at the wrong angle on the medicine bottle body 3.

[0042] When the two dial gauges 12 generate abnormal data feedback, the audible and visual alarm 17 will automatically trigger an audible and visual alarm.

[0043] A driven plate 13 is rotatably mounted on the driven clamp 5 and at the position corresponding to the inner rotating plate 7. A clamping component is installed on the distance adjustment module in conjunction with the clamping component, and a clamping clamp 14 that can be raised and lowered and corresponds to the position of the force measuring plate 8 is provided on the clamping component.

[0044] It also includes a material feeding push rod 23 installed on the conveyor frame 15 and a waste storage box 24 snapped onto the conveyor frame 15.

[0045] By setting up the feeding pusher 23 and the waste storage box 24, the unqualified medicine bottle body 3 can be classified and stored.

[0046] The clamping assembly includes a lifting screw 25 rotatably connected to the conveyor frame 15. A bevel gear is installed at the bottom end of the lifting screw 25 and the end of the adjusting screw 21. The two bevel gears mesh with each other. An active pressure table 26 is drivenly connected to the lifting screw 25. The active pressure table 26 is slidably connected to the conveyor frame 15. A set of T-shaped guide rods 27 are installed on the top surface of the clamp 14. Each T-shaped guide rod 27 is slidably connected to the active pressure table 26. A clamping spring 28 is sleeved on each T-shaped guide rod 27 at the position corresponding to the active pressure table 26 and the clamp 14.

[0047] When the medicine bottle body 3 is in the corresponding position of the test plate, the medicine bottle body 3 is limited by the clamp 14, and the force measuring plate 8 applies force to the bottle cap to measure the torque.

[0048] Working principle and usage process of this utility model:

[0049] When the medicine bottle body 3 moves between the outer rotating disk 6 and the dial indicator 12, the medicine bottle body 3 is pressed tightly between the universal steel ball 22 and the outer rotating disk 6. The outer rotating disk 6 drives the medicine bottle body 3 to rotate at a set speed. The rotation of the bottle cap on the medicine bottle body 3 and the eccentric position setting of the two dial indicators 12 are used to monitor whether the bottle cap is misaligned or tightened at the wrong angle on the medicine bottle body 3. When the two dial indicators 12 generate abnormal data feedback, the audible and visual alarm 17 automatically sounds and flashes. When the medicine bottle body 3 moves to a position coaxial with the inner rotating disk 7, the vision probe 11 performs visual recognition of the medicine bottle body 3. Through visual recognition, the angle of the label 20 relative to the vision probe 11 is detected. The microcontroller 16 then... Based on the visual recognition results of the vision probe 11, the arrangement angle of the medicine bottle body 3 on the tray 18 is adjusted by the inner rotating plate 7 and the driven plate 13, so that the label 20 on the medicine bottle body 3 is facing the vision probe 11. By adjusting the angle of the medicine bottle body 3 on the tray 18, the angle and position of the bottle cap can be limited before the test, thereby achieving uniformity of the position before the bottle cap tightness test, and thus improving the measurement accuracy of the device. When the medicine bottle body 3 moves to the coaxial position with the force measuring plate 8, the medicine bottle body 3 is limited by the clamp 14, and the force measuring plate 8 applies force to the bottle cap to measure the torque. Through the setting of the feeding push rod 23 and the waste storage box 24, unqualified medicine bottle bodies 3 are classified and stored.
