Description

Technical Field

[0001] The invention relates to the technical field of medicine packaging, in particular to a device for detecting the number of pinholes in aluminum foil used for medicine packaging. Background Art

[0002] Pharmaceutical packaging refers to a container or material system that is used to protect drugs from contamination and damage by moisture, light, microorganisms and other factors, to ensure the stability and effectiveness of drugs, and to facilitate storage, transportation and use. The detection of the number of pinholes in aluminum foil is an important part of the quality control of pharmaceutical packaging, especially for blister packaging, commonly known as aluminum-plastic packaging. This detection is mainly to ensure the sealing and integrity of the packaging to prevent the drugs from being affected by the external environment.

[0003] For example, the invention with publication number CN106596576B discloses a device for detecting the number of pinholes in aluminum foil for drug packaging. The invention has achieved the effect of convenient and simple operation and low cost. When using the device, the staff moves the first support rod alternately left and right, so that the first placement plate and the second placement plate continuously rotate alternately clockwise and counterclockwise, and the rotation directions of the first placement plate and the second placement plate are opposite, so that the red ink on the sponge and the aluminum foil are fully in contact, thereby increasing the detection effect. However, in actual use, the aluminum foil to be detected will be contaminated by the red ink. Therefore, when the aluminum foil needs to be recycled, it needs to be cleaned, and the aluminum foil may be damaged during the cleaning process. In addition, the placement plate needs to be cleaned after the detection, which is still a time-consuming and labor-intensive problem during use.

[0016] The present invention provides a device for detecting the number of pinholes in aluminum foil for drug packaging, which has the following beneficial effects:

[0017] 1. After the aluminum foil is placed above the light board, the aluminum foil will block the light from the light board and light will leak at the pinholes of the aluminum foil. Therefore, the visual detection camera can be used to capture and detect the light leakage. At the same time, the motor drives the second reciprocating screw to rotate, so that the hanger can move on the light rod to perform visual detection on different positions on the aluminum foil. In the process of the hanger moving toward the tooth plate, the pulley seat will first fit with the side frame to limit the movement of the pulley seat, so that the buffer spring will be compressed. At this time, the hanger will also squeeze the tooth plate, so that it passes through the gear shaft, the transmission box, the first synchronous pulley group and the second synchronous pulley group, so that the first reciprocating screws on both sides rotate at the same time, thereby changing the position of the moving seat. Therefore, during use, the detection range of the visual detection camera can cover the entire aluminum foil without adding an additional power source, thereby reducing the cost of use.

[0018] 2. In the present invention, when the hanger squeezes the toothed plate and drives the toothed shaft to rotate counterclockwise, it will also drive the synchronous gear to rotate in the same direction. In this process, the idling gear will also be caused to rotate clockwise through the transmission gear, and under the squeezing of the second spring seat, the blocking block will be tightly attached to the ratchet. Therefore, the blocking block on the idling gear will drive the driving shaft to rotate clockwise through the ratchet, and the blocking block on the synchronous gear will slip with the ratchet due to reverse movement, so that no transmission will be performed. Subsequently, when the first spring seat drives the toothed plate to reset, the toothed shaft will rotate clockwise. Similarly, the blocking block on the synchronous gear will drive the driving shaft to rotate clockwise through the ratchet, and the blocking block on the idling gear will slip with the ratchet due to counterclockwise movement. Therefore, the driving shaft can be driven to rotate clockwise during the reciprocating movement of the toothed plate, thereby increasing the moving range of the moving seat through the first synchronous pulley set and the first reciprocating screw.

[0019] 3. According to the present invention, when the hanger moves to the two ends of the second reciprocating screw, the side frame blocks the movement of the pulley seat, thereby changing the relative position between the hanger and the pulley seat, so that the limit plate on the hanger pushes the baffle at the front end of the pulley seat, thereby driving the rack to slide, and the rotating seat can be rotated half a circle by driving the gear, so that the visual detection camera can shoot the surface of the aluminum foil from another angle, reducing the blind area during detection. Therefore, after the visual detection camera moves to the two ends of the aluminum foil, it will hover for a period of time. During this process, the shooting angle of the detection camera will be automatically changed, and after shooting again for verification, the next row will be visually photographed and detected, thereby improving the accuracy of detection. At the same time, the light shield can be used to avoid interference from strong light from the outside, and the cleaning cotton strip can flexibly fill the space between the light shield and the aluminum foil to reduce light leakage. At the same time, the surface of the aluminum foil can also be cleaned during movement to reduce interference from foreign objects.

[0020] 4. In the detection process of the present invention, the clamping plate will clamp and position the aluminum foil under the action of the positioning seat and the torsion spring to prevent it from shifting and skewing, and when the visual detection camera moves toward the clamping plate, the pulley seat will first squeeze the driving plate to make the rotating plate rotate around the fixed axis, so that the fixed ear is squeezed by the slide plate, and the clamping plate can be opened to automatically avoid the visual detection camera, so as to avoid interference with the detection of the number of pinholes in the aluminum foil here due to the obstruction of the clamping plate. At the same time, after the pulley seat is removed, since there is no obstruction on one side of the driving plate, the clamping plate will clamp the aluminum foil again under the action of the torsion spring, so as to automatically clamp and position the aluminum foil, and when taking and placing the aluminum foil, it is only necessary to push the synchronization rod inside the guide groove to make all the rotating plates rotate at the same time, and the clamping plates will open synchronously, so as to facilitate the replacement operation of the aluminum foil.

[0032] The specific operation is as follows. After placing the aluminum foil above the light board 2, the light board 2 is started. The aluminum foil will block the light from the light board 2 and light will leak at the pinholes of the aluminum foil. Therefore, the visual detection camera 6 can be used to take pictures of the light leakage. At the same time, the motor 403 is started by the controller to drive the second reciprocating screw 404 to rotate, so that the suspension seat 405 can be moved on the light rod 406 to perform visual detection on different positions on the aluminum foil. During this process, the internal rubber sleeve at the upper end of the pulley seat 409 can provide a certain damping force between it and the guide rod 407 to avoid vibration under the action of the buffer spring 408. In the process of the suspension seat 405 moving toward the tooth plate 410, the pulley seat 409 will first fit with the side frame 3, thereby limiting the movement of the pulley seat 409. Therefore, the buffer spring 408 will be compressed, and at this time the suspension seat 405 will also squeeze the tooth plate 410, so that it drives the gear shaft 412 to rotate counterclockwise, thereby making the synchronous gear 901 rotate in the same direction, and the idle gear 903 will rotate clockwise through the transmission gear 902, and under the squeezing of the second spring seat 906, the block 907 will be tightly attached to the ratchet 905, so the block 907 on the idle gear 903 will drive the drive shaft 904 to rotate clockwise through the ratchet 905, and the block 907 on the synchronous gear 901 will slip with the ratchet 905 due to the reverse movement, so that no transmission can be performed, and the first reciprocating screws 401 on both sides can be rotated simultaneously through the first synchronous pulley set 414 and the second synchronous pulley set 415, changing the movable seat 40 2. During this process, the side frame 3 will block the movement of the pulley seat 409, thereby changing the relative position between the hanging seat 405 and the pulley seat 409, so that the limit plate 501 on the hanging seat 405 pushes the baffle 502 at the front end of the pulley seat 409, thereby driving the rack 503 to slide, and using the friction force of the rubber block 504 to quickly locate the position of the rack 503 after sliding, the rotating seat 506 can be rotated half a circle by driving the gear 505, so that the visual inspection camera 6 can shoot the surface of the aluminum foil from another angle, reducing the blind area during inspection. Therefore, after the visual inspection camera 6 moves to the two ends of the aluminum foil, it will hover for a period of time. During this process, the shooting angle of the inspection camera will also be automatically changed, and when the hanging seat 405 is reversed When moving to the right, the first spring seat 411 will drive the tooth plate 410 to reset, causing the gear shaft 412 to rotate clockwise. Similarly, the block 907 on the synchronous gear 901 will drive the drive shaft 904 to rotate clockwise through the ratchet 905, and the block 907 on the idle gear 903 will slip with the ratchet 905 due to counterclockwise movement. Therefore, during the reciprocating movement of the tooth plate 410, the drive shaft 904 can be driven to rotate clockwise, thereby increasing the moving range of the moving seat 402 through the first synchronous pulley set 414 and the first reciprocating screw 401. Therefore, during the shooting process, the detection range of the visual detection camera 6 can cover the entire aluminum foil without adding an additional power source, thereby reducing the use cost. At the same time, the use of the sunshade 7 can avoid external strong light interference.The cleaning cotton strip 8 can flexibly fill the space between the light shield 7 and the aluminum foil to reduce light leakage, and can also clean the surface of the aluminum foil during movement to reduce interference from foreign matter.

[0033] See also Figures 7 and 8 , a positioning assembly 10 is arranged between the side frames 3, the positioning assembly 10 includes a fixed shaft 1001, a rotating plate 1002 and a driving plate 1003, a fixed shaft 1001 is arranged between the side frames 3, and the outer side of the fixed shaft 1001 is rotatably connected with the rotating plate 1002, the upper end side of the rotating plate 1002 is slidably connected with the driving plate 1003, and the driving plate 1003 is slidably connected with the side frame 3, the positioning assembly 10 also includes a slide plate 1004 and a fixed ear 1005, the lower end side of the rotating plate 1002 is slidably connected with the slide plate 1004, and the slide plate 1004 is slidably connected with the workbench 1, and the slide plate 100 4 is slidably connected to a fixing ear 1005, the positioning assembly 10 also includes a clamping plate 1006, a positioning seat 1007 and a torsion spring 1008, one end of the fixing ear 1005 is fixed with the clamping plate 1006, and one end of the clamping plate 1006 is internally rotatably connected to the positioning seat 1007, torsion springs 1008 are fixed to both sides of the clamping plate 1006, and the torsion spring 1008 is fixedly connected to the fixing ear 1005, the positioning assembly 10 also includes a guide groove 1009 and a synchronization rod 1010, the inner sides of both ends of the side frame 3 are provided with guide grooves 1009, and the inside of the guide grooves 1009 is slidably connected to the synchronization rod 1010;

[0034] The specific operation is as follows: first push the synchronization rod 1010 inside the guide groove 1009, so that all the rotating plates 1002 can rotate at the same time, so that the fixed ear 1005 is squeezed by the slide plate 1004, so that the clamping plate 1006 is opened synchronously, and then the aluminum foil is placed on the light board 2 and then released. The clamping plate 1006 will clamp and position the aluminum foil under the action of the positioning seat 1007 and the torsion spring 1008 to prevent it from deviating and skewing. In the process of use, when the visual inspection camera 6 moves to the clamping plate 1006, the pulley seat 409 will first squeeze the driving plate 1003, so that the rotating plate 1002 rotates around the fixed axis 1001, so that the fixed ear 1005 is squeezed by the slide plate 1004, so that the clamping plate 1006 can be opened, and automatically avoid the visual detection camera 6, so as to avoid interference with the number of pinholes in the aluminum foil here due to the obstruction of the clamping plate 1006. At the same time, after the pulley seat 409 is removed, since there is no obstruction on one side of the driving plate 1003, the clamping plate 1006 will clamp the aluminum foil again under the action of the torsion spring 1008, thereby automatically clamping and positioning the aluminum foil.

[0035] In summary, when using the device for detecting the number of pinholes in aluminum foil for pharmaceutical packaging, first push the synchronization rod 1010 inside the guide groove 1009 to make all the rotating plates 1002 rotate at the same time, so that the fixing ears 1005 are squeezed by the slide plate 1004 to make the clamping plates 1006 open synchronously, and then place the aluminum foil on the top of the light board 2 and let go. The clamping plates 1006 will clamp and position the aluminum foil under the action of the positioning seat 1007 and the torsion spring 1008. Secondly, start the light board 2, the aluminum foil will block the light of the light board 2, and light will leak at the pinholes of the aluminum foil. Therefore, the visual detection camera 6 can take pictures of the light leakage to detect the number of pinholes. Then, the motor 403 is started by the controller to drive the second reciprocating screw 404 to rotate. The hanger 405 can be moved on the light rod 406 to visually inspect different positions on the aluminum foil, and in the process of the hanger 405 moving toward the tooth plate 410, the pulley seat 409 will first fit with the side frame 3, thereby limiting the movement of the pulley seat 409, so that the buffer spring 408 will be compressed, and at this time the hanger 405 will also squeeze the tooth plate 410, so that it drives the gear shaft 412 to rotate counterclockwise, thereby making the synchronous gear 901 rotate in the same direction, and the idle gear 903 will rotate clockwise through the transmission gear 902, and under the squeezing of the second spring seat 906, the block 907 will be tightly attached to the ratchet 905, so the block 907 on the idle gear 903 will drive the drive shaft 904 to rotate clockwise through the ratchet 905, and the synchronous gear The block 907 on 901 will slip with the ratchet wheel 905 due to the reverse movement and will not transmit the power. Therefore, the first reciprocating screws 401 on both sides can be rotated at the same time through the first synchronous pulley set 414 and the second synchronous pulley set 415, so that the position of the moving seat 402 can be changed. In this process, since the side frame 3 will block the movement of the pulley seat 409, the limit plate 501 will push the baffle plate 502, thereby driving the rack 503 to slide, and the friction force of the rubber block 504 can be used to quickly locate the position of the rack 503 after sliding, and the rotating seat 506 can be rotated half a circle by driving the gear 505, so that the visual inspection camera 6 can shoot the surface of the aluminum foil from another angle, reducing the blind area during inspection. Then, when the hanging seat 405 moves in the opposite direction, When the gear plate 410 is in motion, the first spring seat 411 will drive the toothed plate 410 to reset, causing the gear shaft 412 to rotate clockwise. Similarly, the block 907 on the synchronous gear 901 will drive the drive shaft 904 to rotate clockwise through the ratchet 905, and the block 907 on the idle gear 903 will slip with the ratchet 905 due to counterclockwise rotation. Therefore, during the reciprocating movement of the toothed plate 410, the drive shaft 904 can be driven to rotate clockwise, thereby increasing the moving range of the moving seat 402 through the first synchronous pulley set 414 and the first reciprocating screw 401. Therefore, during the shooting process, the detection range of the visual detection camera 6 can cover the entire aluminum foil without adding an additional power source, thereby reducing the use cost. At the same time, the light shielding cover 7 can avoid external strong light interference.The cleaning cotton strip 8 can flexibly fill the space between the light shield 7 and the aluminum foil to reduce light leakage. Finally, when the visual inspection camera 6 moves toward the clamping plate 1006, the pulley seat 409 will first squeeze the driving plate 1003, so that the rotating plate 1002 rotates around the fixed axis 1001, thereby squeezing the fixed ear 1005 through the slide plate 1004, so that the clamping plate 1006 can be opened to automatically avoid the visual inspection camera 6. At the same time, after the pulley seat 409 is removed, since there is no obstruction on one side of the driving plate 1003, the clamping plate 1006 will clamp the aluminum foil again under the action of the torsion spring 1008 to prevent it from deflecting.
