Description

Technical Field

[0001] This invention relates to the field of light-shielding detection technology for liquid medicine bottles, and more particularly to a light-shielding detection device for oral liquid medicine bottles. Background Technology

[0002] The liquid medicine inside oral medication bottles needs to be protected from light to preserve its quality. Protective coloring is added during the manufacturing process of oral medication bottles. To ensure that this protective coloring doesn't leak and prevent light transmission from accelerating the deterioration of the liquid medicine, the light-blocking degree of the protective coloring on the oral medication bottle usually needs to be tested. There are several methods for testing the light-blocking degree of oral medication bottles. One relatively convenient method is the non-cutting test of oral medication bottles. Specifically, a light source is inserted into the bottle, which is placed in a closed space. An illuminance meter is placed on one side of the bottle, and the illuminance meter collects the intensity of the light transmitted through the bottle. The intensity obtained is compared with the intensity of light transmitted through a standard empty bottle to determine the light-blocking degree of the oral medication bottle with protective coloring.

[0003] Currently, the equipment used to obtain the light transmittance of oral liquid medicine bottles mainly includes a sealed box with an openable door on one side. Inside the sealed box is a rotatable platform with a height-adjustable light source above it. An illuminance meter is installed on one side of the sealed box, and the probe on the illuminance meter is located inside the sealed box and can move up and down. When detecting the light transmittance of an oral liquid medicine bottle, the bottle is placed on the platform, and the light source is inserted into the bottle. After the light source is turned on, the bottle transmits light, and the probe obtains the intensity of the light emitted by the bottle. By controlling the rotation of the platform, the bottle is rotated, and the probe is moved up and down to receive the intensity of the light emitted from different heights of the bottle's perimeter.

[0004] However, the above-mentioned existing technologies still have shortcomings in use: oral liquid medicine bottles have a periphery and a bottom. After the oral liquid medicine bottle is placed on the placement platform, its bottom will be blocked. When the illuminance meter probe detects, it is difficult to detect the light intensity of the periphery and bottom of the bottle after the bottle is placed once. It is necessary to place it twice to detect it completely. The second placement will take up a lot of time and greatly reduce the efficiency of light-blocking detection.

[0005] Therefore, the present invention proposes a light-shielding detection device for oral liquid medicine bottles. Summary of the Invention

[0006] The purpose of this invention is to provide a light-shielding detection device for oral liquid medicine bottles in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A light-shielding detection device for oral liquid medicine bottles includes a sealed light-shielding box, an illuminance meter, and a light source.

A motor is fixedly connected to the top of the outer side of the enclosed light-shielding box. The output shaft of the motor is fixedly connected to one end of one of the inner shafts. A groove adapted to the limiting disc wheel is opened on one side of the rubber sealing block. A sealing plate adapted to the groove is fixedly connected to one side of the square window.

[0010] As a further description of the above technical solution: The drive belt assembly includes a support shaft, a tensioning structure, and a motor. There are two support shafts, and their tops are rotatably connected to the top of the enclosed light-shielding box. The bottom ends of the two support shafts are fixedly connected to pulleys connected by a transmission belt. The top wall of the wheel frame on the tensioning structure is fixedly connected to the top wall of the enclosed light-shielding box. The tensioning wheel on the tensioning structure abuts against one side of the transmission belt. The motor is fixedly mounted on the top wall outside the enclosed light-shielding box, and its output shaft is fixedly connected to the top of one of the support shafts.

[0011] As a further description of the above technical solution: The sliding assembly includes a guide shaft, a reciprocating screw, and a second motor. One end of the guide shaft is fixedly connected to one side of the inclined beam. The other side of the mounting base is fixedly connected to a guide sleeve sleeved outside the guide shaft via a connecting arm. The lead sleeve on the reciprocating screw is fixedly mounted on the connecting arm. A machine base is fixedly connected to one end of the outer wall of the guide shaft. The second motor is fixedly mounted on one side of the machine base, and its output shaft is fixedly connected to one end of the lead screw of the reciprocating screw.

[0012] As a further description of the above technical solution: The lower part of the enclosed light-shielding box is an inclined plate. A positioning shaft is fixedly connected to one side of the inclined beam near the other end. The positioning shaft and the inclined plate are rotatably connected. A motor is fixedly connected to the outside of the inclined plate through a base. A drive gear is fixedly connected to the output shaft of the motor. A driven gear that meshes with the drive gear is fixedly sleeved on the outside of the positioning shaft.

[0013] As a further description of the above technical solution: The bottle neck clip has a disc structure with a through hole in the middle. The outer periphery of the bottle neck clip has a U-shaped groove that communicates with the through hole. The inner wall of the U-shaped groove is coated with a sealing layer.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, by setting up a vertical rotating tube, a friction transmission wheel, a transmission belt, a bottle mouth clamp, an inclined beam, and a sliding assembly, the probe on the illuminometer can switch positions and move, enabling the detection of the light intensity penetrating the outer and bottom walls of the oral liquid bottle. Compared with the prior art, this setup has the advantage of no blind spots in detecting the light occlusion of the oral liquid bottle after it has been placed once, greatly improving the efficiency of oral liquid bottle detection.

[0016] 2. In this invention, a horizontal transmission ring, a rubber sealing block, and a square window are set up. Then, two symmetrically distributed vertical rotating tubes are set on the horizontal transmission ring. The bottom of the vertical rotating tubes is connected to a bottle mouth clamp, which has the function of quickly hanging the oral liquid bottle. When the horizontal transmission ring rotates, it can drive a suspended oral liquid bottle into and out of the closed light-shielding box. Moreover, when one oral liquid bottle is inside the closed light-shielding box, the other oral liquid bottle is outside the closed light-shielding box. This arrangement makes the loading and unloading operation of oral liquid bottles more convenient.

[0017] 3. In this invention, by setting a U-shaped slot and a clearance notch, the hanging installation and disassembly of the oral liquid medicine bottle are more convenient. When the vertical rotating tube rotates, it can drive the oral liquid medicine bottle to rotate stably without shaking, which can ensure the accuracy of light intensity detection.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please see Figure 1-8 An occlusion detection device for oral liquid medicine bottles includes a sealed occlusion box 1, an illuminometer 2, and a light source 3. The illuminometer 2 includes a probe 21. The illuminometer is used to detect the light transmittance when testing new materials for oral liquid medicine bottles, and then the occlusion degree of the oral liquid medicine bottle is obtained according to relevant standards. The probe 21 is used to receive the light that passes through the oral liquid medicine bottle from the inside. The probe 21 and the wire are connected to the illuminometer 2. The illuminometer 2 is fixedly installed on the top wall outside the sealed occlusion box 1. The inner cavity of the sealed occlusion box 1 is a dark space for occlusion degree detection.

[0022] The top of the enclosed light-shielding box 1 is equipped with a lifting shaft 4, which runs through the top of the enclosed light-shielding box 1 and is slidably sealed to the lifting shaft 4. Specifically, a sleeve is fixedly connected to the top of the enclosed light-shielding box 1 and is fitted outside the lifting shaft 4. The lifting shaft 4 and the sleeve are slidably connected. A sealing rubber sleeve is fixedly fitted inside the sleeve and is located outside the lifting shaft 4. The sealing rubber sleeve is used to eliminate the gap between the lifting shaft 4 and the sleeve. The top of the enclosed light-shielding box 1 is fixedly connected with a sealing sleeve 15 fitted outside the lifting shaft 4. An electric push rod 107 located on one side of the lifting shaft 4 is fixedly connected to the top wall of the enclosed light-shielding box 1. The output shaft of the electric push rod 107 is fixedly connected to the top wall of the lifting shaft 4 through a connecting arm. The electric push rod 107 is a servo electric cylinder. The function of the electric push rod 107 is to control the up and down movement of the lifting shaft 4. The bottom of the lifting shaft 4 is fixedly connected to a light source 3 located inside the enclosed light-shielding box 1. This light source 3 is used to provide light for the light-shielding test. In specific implementation, the light source 3 is a cylindrical lamp tube. When in use, an adjuster (not shown in the figure) for adjusting the brightness of the light source 3 can be installed on the top wall outside the enclosed light-shielding box 1. The operator adjusts the brightness of the light emitted by the light source 3 by using the button on the adjuster. When the lifting shaft 4 moves up and down, it can drive the light source 3 to move up and down.

[0023] A horizontal transmission ring 5 is rotatably connected to the enclosed light-shielding box 1. A part of the horizontal transmission ring 5 is located inside the enclosed light-shielding box 1. In specific implementation, the enclosed light-shielding box 1 has a cylindrical structure and two square windows 11 on its outer wall to make way for the horizontal transmission ring 5. Two symmetrically distributed vertical rotating tubes 6 are installed through the horizontal transmission ring 5. In specific implementation, a connecting hole is installed through the horizontal transmission ring 5 and sleeved on the outside of the vertical rotating tube 6. The connecting hole and the vertical rotating tube 6 are rotatably connected. A bottle mouth clamp 104 through which the light source 3 can pass is fixedly connected to the bottom of the vertical rotating tube 6. When one bottle mouth clamp 104 is located inside the enclosed light-shielding box 1, the other bottle mouth clamp 104 is located outside the enclosed light-shielding box 1. When the horizontal transmission ring 5 rotates, it can drive the bottle mouth clamp 104 in and out of the enclosed light-shielding box 1. The function of the bottle mouth clamp 104 is to seal and hang the oral medicine bottle. When hanging, the bottle mouth of the oral medicine bottle is hung with the bottle mouth clamp 104. When the horizontal transmission ring 5 rotates, one of its vertical rotating tubes 6 is located directly below the light source 3. After the vertical rotating tube 6 is located directly below the light source 3, when the light source 3 is controlled to descend, it can pass through the vertical rotating tube 6 and then enter the oral liquid bottle. It should be noted that when the light source 3 reaches the position required for detection, one end of the bottom of the lifting shaft 4 will enter the mouth of the oral liquid bottle. The outside of the lifting shaft 4 is coated with a sealing soft coating near the bottom. When the bottom part of the lifting shaft 4 enters the mouth of the oral liquid bottle, the sealing soft coating will adhere to the inner wall of the mouth of the oral liquid bottle. The adhesion pressure here is small, the purpose of which is not to affect the rotation of the vertical rotating tube 6. The rotation of the vertical rotating tube 6 can drive the mouth-locking oral liquid bottle to rotate through the bottle mouth locking component 104. The bottle neck retainer 104 has a disc structure with a through hole 1041 in the center. The through hole 1041 is opposite to the bottom opening of the vertical rotating tube 6. A U-shaped groove 1042 communicating with the through hole 1041 is formed on the outer periphery of the bottle neck retainer 104. The inner wall of the U-shaped groove 1042 is coated with a sealing layer. A clearance notch 1043 communicating with the U-shaped groove 1042 is formed at the bottom of the bottle neck retainer 1044. The clearance notch 1043 is also U-shaped. The bottle neck of the oral liquid bottle is T-shaped. When the bottle neck of the oral liquid bottle is inserted horizontally into the U-shaped groove 1042, the bottle neck of the oral liquid bottle will abut against the sealing layers on the upper and lower sides of the U-shaped groove 1042. The sealing layer is a soft rubber layer, which prevents light leakage at the bottle neck of the oral liquid bottle located in the U-shaped groove 1042.

[0024] A friction drive wheel 7 is fixedly fitted on the outside of the vertical rotating tube 6. When the friction drive wheel 7 rotates, it can drive the vertical rotating tube 6 to rotate. A rubber sleeve is fixedly fitted on the outside of the friction drive wheel 7. The function of the rubber sleeve is to increase the contact friction. A drive belt assembly 8 is provided in the upper part of the enclosed light-shielding box 1, located on one side of the lifting shaft 4. The drive belt assembly 8 includes a transmission belt 81 that works with the friction drive wheel 7. Specifically, after the outer peripheral wall of the friction drive wheel 7 and the belt body of the transmission belt 81 are in contact, the transmission belt 81 can drive the friction drive wheel 7 to rotate through the rubber sleeve when it runs. In other words, the function of the drive belt assembly 8 is to provide driving force for the rotation of the friction drive wheel 7.

[0025] An inclined beam 9 is installed at the lower part of the enclosed light-shielding box 1. The inclined beam 9 has an inclination angle of 45° relative to the horizontal plane. One side of the inclined beam 9 is rotatably connected to one side of the enclosed light-shielding box 1. In a preferred embodiment, the lower part of the enclosed light-shielding box 1 is an inclined plate 14. One side of the inclined beam 9 is fixedly connected to a positioning shaft 91 near the other end. The positioning shaft 91 and the inclined plate 14 are rotatably connected. Specifically, a limiting sleeve is fixedly connected to the inclined plate 14 and sleeved outside the positioning shaft 91. The limiting sleeve and the positioning shaft 91 are rotatably connected. A motor 105 is fixedly connected to the outside of the inclined plate 14 through a base 131. The motor 105 is a servo motor. The output shaft of the motor 105 is fixedly connected to a drive gear 1051. A driven gear 911 that meshes with the drive gear 1051 is fixedly sleeved outside the positioning shaft 91. The motor 105 drives the positioning shaft 91 to rotate through the meshing of the drive gear 1051 and the driven gear 911, thereby driving the inclined beam 9 to rotate. On the other side of the inclined beam 9, a sliding assembly 101 is provided near one end. When the inclined beam 9 rotates, it can drive the sliding assembly 101 to revolve. The sliding assembly 101 includes a movable mounting base 1011. The probe 21 is fixedly mounted on one side of the mounting base 1011. When the mounting base 1011 moves, it can drive the probe 21 to move. When the inclined beam 9 rotates to the lowest point of the probe 21, the probe 21 is located below the bottle mouth clamp 104 opposite to the light source 3. When the bottle mouth clamp 104 is attached to the oral medication bottle, the probe 21 is located below the oral medication bottle, and the probe 21 can receive the oral medication bottle. The light transmitted through the bottom of the oral liquid bottle; when the inclined beam 9 rotates to the highest point of the probe 21, the probe 21 is located on one side of the bottle mouth clamp 104 opposite the light source 3 and can move up and down. When the bottle mouth clamp 104 is attached to the oral liquid bottle, the probe 21 is located on one side of the oral liquid bottle. At this time, the up and down movement of the mounting base 1011 can drive the probe 21 to move up and down. The probe 21 can receive the light transmitted through various parts of the oral liquid bottle's perimeter wall. This function, combined with the rotation function of the oral liquid bottle, allows the probe 21 to receive the light transmitted through various positions of the oral liquid bottle's perimeter wall. Therefore, the light-blocking degree of the oral liquid bottle can be fully detected by placing it once.

[0026] The sliding assembly 101 includes a guide shaft 1012, a reciprocating screw 1014, and a second motor 1013. One end of the guide shaft 1012 is fixedly connected to one side of the inclined beam 9. The other side of the mounting base 1011 is fixedly connected to a guide sleeve 10111 sleeved on the outside of the guide shaft 1012 via a connecting arm. The thread sleeve 10141 on the reciprocating screw 1014 is fixedly mounted on the connecting arm. The outer wall of the guide shaft 1012 is fixedly connected to a base 10121 near one end. The second motor 1013 is fixedly mounted on one side of the base 10121, and its output shaft is fixedly connected to one end of the screw 10142 of the reciprocating screw 1014. The second motor 1013 is a servo motor, which provides driving force to the rotation of the screw 10142. When the screw 10142 rotates, it can drive the mounting base 1011 to move along the axial direction of the guide shaft 1012 through the thread sleeve 10141.

[0027] In this embodiment, the cylindrical structure of the enclosed light-shielding box 1 has two square windows 11 on its outer wall to make way for the horizontal transmission ring 5. The horizontal transmission ring 5 is fixedly fitted with rubber sealing blocks 51 that seal with the square windows 11. There are also two rubber sealing blocks 51. When the rubber sealing blocks 51 are in the square windows 11, the square windows 11 will be blocked by the rubber sealing blocks 51. That is to say, when a vertical rotating tube 6 is located directly below the light source 3, the two rubber sealing blocks 51 will be located in the two square windows 11 respectively.

[0028] Furthermore, at least one limiting disc wheel 102 is provided both inside and outside the enclosed light-shielding box 1, meshing with the inner peripheral wall of the horizontal transmission ring 5. There are two limiting disc wheels 102 inside the enclosed light-shielding box 1, and one limiting disc wheel 102 outside the enclosed light-shielding box 1. Specifically, an annular groove is formed on the inner peripheral wall of the horizontal transmission ring 5, and a ring of teeth is formed at the bottom of the groove. A portion of the limiting disc wheel 102 is inserted into the annular groove. The limiting disc wheel 102 has a gear structure and meshes with the teeth. It should be noted that the three limiting disc wheels 102 will limit the horizontal transmission ring 5 vertically and laterally through the annular groove. To eliminate the friction between the limiting disc wheels 102 and the upper and lower side walls of the annular groove, a ring of ball bearings can be provided on the upper and lower sides of the annular groove. An inner shaft 12 is fixedly connected to one side of the limiting disc wheel 102 inside the enclosed light-shielding box 1. The top of the inner shaft 12 and the top of the enclosed light-shielding box 1 rotate... The outer frame 13 is fixedly connected to the outer peripheral wall of the enclosed light-shielding box 1 and is rotatably connected to the limiting disc wheel 102 outside the enclosed light-shielding box 1. The top of the enclosed light-shielding box 1 is fixedly connected to the motor 4 106, which is a servo motor. The output shaft of the motor 4 106 is fixedly connected to one end of one of the inner shafts 12. When the motor 4 106 starts, it can drive the corresponding limiting disc wheel 102 to rotate through the corresponding inner shaft 12, which in turn can drive the horizontal transmission ring 5 to rotate. The rubber sealing block 51 has a groove 511 adapted to the limiting disc wheel 102 on one side. This groove 511 is used to make way for the limiting disc wheel 102, so as not to affect the normal rotation of the horizontal transmission ring 5. A sealing plate 111 adapted to the groove 511 is fixedly connected to one side inside the square window 11. The sealing plate 111 is a soft rubber plate, which is used to seal the groove 511 located at the square window 11.

[0029] In this embodiment, the drive belt assembly 8 includes a support shaft 82, a tensioning structure 83, and a motor 84. There are two support shafts 82, and their tops are rotatably connected to the top of the enclosed light-shielding box 1. The bottom ends of the two support shafts 82 are fixedly connected to pulleys 821 connected by a transmission belt 81. The top wall of the wheel frame 831 on the tensioning structure 83 is fixedly connected to the top wall of the enclosed light-shielding box 1. The tensioning wheel 832 on the tensioning structure 83 abuts against one side of the transmission belt 81. Specifically, the tensioning wheel 832 abuts against the transmission belt 81 under the elastic thrust of the tensioning spring on the tensioning structure 83, so that the transmission belt 81 is compressed and tensioned. The motor 84 is fixedly installed on the top wall outside the enclosed light-shielding box 1, and its output shaft is fixedly connected to the top of one of the support shafts 82. The motor 84 provides driving force to the rotation of the support shaft 82. The motor 84 is a servo motor.

[0030] Working principle: Before use, connect the aforementioned motor 1 (84), motor 2 (1013), motor 4 (106), motor 5 (105), illuminance meter 2, light source 3, and electric push rod 107 to the controller (PLC). The controller has built-in control. When using, first prepare a transparent empty oral medicine bottle as a standard bottle. Place this standard bottle into the U-shaped slot 1042 of the bottle mouth clamp 104 outside the sealed light-shielding box 1. At this time, the empty oral medicine bottle and the vertical rotating tube 6 are coaxial and connected. Then start motor 4 (106). Motor 4 (106) drives the limit disc wheel 102 to rotate through the inner shaft 12. Under the meshing engagement, the horizontal transmission ring 5 rotates, allowing the empty oral medicine bottle to pass through. After the square window 11 enters directly below the light source 3 and stops, it should be noted that when the horizontal transmission ring 5 is running, the motor 84 is also in the starting state, causing the transmission belt 81 to run. This running state allows one of the rubber sealing blocks 51 to still operate normally when it contacts the transmission belt 81. After the empty oral medicine bottle is located directly below the light source 3, the friction transmission wheel 7 and the transmission belt 81 press against each other. The electric push rod 107 is activated to drive the lifting shaft 4 to descend. The descent of the lifting shaft 4 will cause the light source 3 to pass through the vertical rotating tube 6 and the through hole 1041 and enter the empty oral medicine bottle. Then, the light source 3 is controlled to turn on, and the light emitted by the light source 3 penetrates the empty oral medicine bottle. Then, motor 5 (105) is started. Under the meshing transmission of the driving gear 1051 and the driven gear 911, the positioning shaft 91 drives the inclined beam 9 to rotate until the probe 21 is located on one side of the peripheral wall of the oral medicine bottle. Then, motor 1 (84) is started. Driven by pulley 821, the transmission belt 81 rotates. The transmission belt 81 uses friction to drive the corresponding friction transmission wheel 7 to rotate, which in turn drives the oral medicine bottle attached to the bottle mouth clamp 104 to rotate through the corresponding vertical rotating tube 6. When the oral medicine bottle rotates, the probe 21 can receive light from a certain height position on the peripheral wall of the oral medicine bottle. After the oral medicine bottle rotates one revolution, motor 2 (1013) is started, and the lead screw 10142 rotates. The mounting base 1011 is moved by the threaded sleeve 10141, thereby changing the height of the probe 21. This allows it to receive light emitted from another height position in the axial direction of the empty oral medicine bottle. In this way, the probe 21 can detect the intensity of all light emitted from the periphery of the empty oral medicine bottle. Then, the motor 105 is started, causing the inclined beam 9 to rotate 180°, so that the probe 21 is located below the empty oral medicine bottle. Then, the motor 1013 is started to place the probe 21 directly below the empty oral medicine bottle. At this time, the probe 21 can detect the intensity of light emitted from the bottom of the empty oral medicine bottle. Thus, the illuminance meter 2 obtains the standard light transmittance intensity of the transparent empty oral medicine bottle.Then, a bottle with protective color is hung on another bottle mouth clip 104 outside the sealed light-shielding box 1. The light source 3 is controlled to rise and detach from the corresponding vertical rotating tube 6. Then, the horizontal transmission ring 5 is controlled to rotate so that the standard empty bottle is driven to the outside of the sealed light-shielding box 1. The bottle with protective color enters directly below the light source 3. Then, the intensity of the light on the outer wall of the bottle with protective color is obtained in the above manner. The light-shielding degree of the bottle with protective color is obtained by comparing this intensity with the intensity of the standard empty bottle.
