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 the container or material system used to protect drugs from contamination and damage by factors such as moisture, light, and microorganisms, ensuring the stability and effectiveness of the drugs, while also facilitating storage, transportation, and use. Pinhole count detection in aluminum foil is a key step in pharmaceutical packaging quality control, especially for blister packaging, commonly known as aluminum-plastic packaging. This test is primarily intended to ensure the sealing and integrity of the packaging, protecting the drugs from the external environment.

[0003] For example, the invention with publication number CN106596576B discloses a device for detecting the number of pinholes in aluminum foil used for pharmaceutical packaging. This invention achieves the advantages of convenient, simple operation and low cost. When using this device, a worker alternately moves the first support rod left and right, causing the first and second placement plates to continuously rotate clockwise and counterclockwise. The first and second placement plates rotate in opposite directions, ensuring that the red ink on the sponge and the aluminum foil fully contact each other, improving the detection effect. However, in actual use, this type of device may contaminate the aluminum foil to be tested due to the red ink. Therefore, when the aluminum foil needs to be recycled, it must be cleaned, and the cleaning process may also damage the aluminum foil. In addition, the placement plates must be cleaned after testing, resulting in a relatively time-consuming and labor-intensive use.

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

[0017] 1. After the aluminum foil is placed above the lamp board, the aluminum foil will block the light from the lamp board and light will leak at the pinholes of the aluminum foil. Therefore, the visual detection camera can be used to photograph 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 optical 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, thereby limiting 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, transmission box, first synchronous pulley set and second synchronous pulley set, 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 tooth plate, causing it to drive the gear shaft to rotate counterclockwise, it will also drive the synchronous gear to rotate in the same direction. In this process, the idle gear will also be driven to rotate clockwise through the transmission gear, and under the extrusion of the second spring seat, the block will be tightly attached to the ratchet. Therefore, the block on the idle gear will drive the drive shaft to rotate clockwise through the ratchet, and the block on the synchronous gear will slip with the ratchet due to reverse movement, and thus no transmission will be performed. Subsequently, when the first spring seat drives the tooth plate to reset, the tooth shaft will be rotated clockwise. Similarly, the block on the synchronous gear will drive the drive shaft to rotate clockwise through the ratchet, and the block on the idle gear will slip with the ratchet due to counterclockwise movement. Therefore, the drive shaft can be driven to rotate clockwise during the reciprocating movement of the tooth plate, thereby increasing the moving range of the movable 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 will block 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 avoid external strong light interference, 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 matter.

[0020] 4. During the detection process of the present invention, the splint will clamp and position the aluminum foil under the action of the positioning seat and the torsion spring to prevent it from shifting and tilting, and when the visual detection camera moves toward the splint, 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 splint 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 splint. At the same time, after the pulley seat is removed, since there is no obstruction on one side of the driving plate, the splint will clamp the aluminum foil again under the action of the torsion spring, thereby automatically clamping and positioning 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 splints will open synchronously, thereby facilitating the replacement operation of the aluminum foil.

[0032] The specific operation is as follows: after the aluminum foil is placed above the light board 2, the light board 2 is started, and 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 photograph and detect 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 hanger 405 can be moved on the optical rod 406 to perform visual inspection 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, 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. Therefore, the buffer spring 408 will be compressed, and at this time the hanger 405 will also squeeze the tooth plate 410, causing it to drive the gear shaft 412 to rotate counterclockwise, thereby causing the synchronous gear 901 to rotate in the same direction, which will cause the idle gear 903 to rotate clockwise through the transmission gear 902, and under the pressure of the second spring seat 906, the block 907 will be tightly attached to the ratchet 905, so that 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, thereby changing the movable seat 40 2. During this process, the side frame 3 blocks 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 after the rack 503 slides, 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 the gear plate 410 moves to the left, the first spring seat 411 will drive the gear 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 against the ratchet 905 due to counterclockwise movement. Therefore, during the reciprocating movement of the gear plate 410, the drive shaft 904 can be driven to rotate clockwise, thereby increasing the moving range of the movable base 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 shield 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. It 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 provided 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 placed between the side frames 3, and the outer side of the fixed shaft 1001 is rotatably connected to the rotating plate 1002, the upper end side of the rotating plate 1002 is slidably connected to the driving plate 1003, and the driving plate 1003 is slidably connected to 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 to the slide plate 1004, and the slide plate 1004 is slidably connected to the workbench 1, the slide plate 100 4 is slidably connected to a fixed 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 to the clamping plate 1006, and one end of the clamping plate 1006 is internally connected to the positioning seat 1007 for rotation, and torsion springs 1008 are fixed on both sides of the clamping plate 1006, and the torsion springs 1008 are 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 a guide groove 1009, and the interior of the guide groove 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, thereby squeezing the fixed ear 1005 through 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 the aluminum foil under the action of the positioning seat 1007 and the torsion spring 1008 to prevent it from deviating and tilting. 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, causing the rotating plate 1002 to rotate around the fixed axis 1001, thereby squeezing the fixed ear 1005 through the slide plate 1004, so that the splint 1006 can be opened, automatically avoiding the visual inspection camera 6, to avoid interference with the detection of the number of pinholes in the aluminum foil here due to the obstruction of the splint 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 splint 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, so that all the rotating plates 1002 can rotate at the same time, thereby squeezing the fixed ear 1005 through the slide plate 1004 to make the splint 1006 open synchronously, and then place the aluminum foil on the top of the light board 2 and let go. The splint 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 polished rod 406 so as to perform visual inspection on different positions on the aluminum foil. 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. Therefore, the buffer spring 408 will be compressed. 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, which will make the idle gear 903 rotate clockwise through the transmission gear 902, and under the pressure of the second spring seat 906, the block 907 will fit tightly with the ratchet 905. Therefore, 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 against the ratchet 905 due to the reverse movement and will not transmit the information. 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, thereby changing the position of the movable seat 402. In this process, the side frame 3 will block the movement of the pulley seat 409, so that the limit plate 501 pushes the baffle 502, 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, 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 gear 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 against the ratchet 905 due to counterclockwise movement. Therefore, during the reciprocating movement of the gear plate 410, the drive shaft 904 can be driven to rotate clockwise, thereby increasing the moving range of the movable base 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 shield 7 can avoid external strong light interference.The cleaning cotton strips 8 can flexibly fill the space between the light shield 7 and the aluminum foil, reducing light leakage. Finally, when the visual inspection camera 6 moves toward the clamping plate 1006, the pulley seat 409 will first squeeze the drive plate 1003, causing the rotating plate 1002 to rotate around the fixed axis 1001. The sliding plate 1004 then squeezes the fixed ear 1005, causing the clamping plate 1006 to open and automatically avoid the visual inspection camera 6. At the same time, after the pulley seat 409 moves away, since there is no obstruction on the side of the drive plate 1003, the torsion spring 1008 will once again clamp the aluminum foil to prevent it from deflecting.
