Description

Technical Field

[0001] The invention relates to the technical field of medicine bottle detection, and in particular to a medicine bottle detection device based on optical principles. Background Art

[0002] The optical principle-based medicine bottle inspection device is a device that uses optical technology to detect the quality and integrity of medicine bottles. This device is often used in the pharmaceutical industry to ensure that the medicine bottles have no defects during the filling, sealing and packaging process, such as cracks, foreign matter, uneven sealing, etc.

[0003] The existing medicine bottle inspection device based on optical principle has insufficient overall coordination when inspecting medicine bottles on batch production lines, which is mainly reflected in the transmission and transfer of medicine bottles, including the input of medicine bottles to be inspected, the transfer between inspection devices, and the sorting and output of normal medicine bottles and medicine bottles with quality problems. In addition, the kinetic energy transmission between the above steps lacks effective linkage, resulting in low overall kinetic energy conversion utilization rate, affecting operation efficiency. Therefore, in view of the above-mentioned problems, the present technical solution proposes a medicine bottle detection device based on optical principles. Summary of the invention

[0004] The purpose of the present invention is to provide a medicine bottle detection device based on optical principles to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a medicine bottle detection device based on optical principles, comprising a U-shaped base, the two ends of the top of the U-shaped base extending outwards, used to form an operating frame of the entire medicine bottle detection device, and a conveyor belt and an output belt are respectively arranged on both sides of the top of the U-shaped base, which are used to input medicine bottles to be detected and output qualified medicine bottles after detection; An optical detection channel is arranged below the output end of the conveyor belt, and is used for mobile optical detection of medicine bottles falling on and off the conveyor belt. An intermittent feeding platform is arranged at the top of the optical detection channel, and the top of the intermittent feeding platform extends to the output end of the conveyor belt, and is used for receiving medicine bottles falling intermittently in the longitudinal direction. The intermittent feeding platform includes a feeding channel which is opened at the center and runs through the top and bottom. An intermittent unloading component is arranged inside the feeding channel, and the intermittent unloading component controls the automatic cyclic falling of medicine bottles. One side of the intermittent unloading component is rotatably connected to the driving shaft on the conveyor belt through a transmission connecting piece, and the transmission connecting piece is used to transfer part of the rotational kinetic energy of the conveyor belt to the intermittent unloading component, thereby controlling the medicine bottles from the conveyor belt. The medicine bottles outputted from the upper conveyor are transferred to the optical detection channel for detection, that is, the speed of the medicine bottles entering the optical detection channel is positively changed with the conveying speed of the medicine bottles on the conveyor belt, so that the kinetic energy is effectively utilized and the efficient detection of medicine bottles of different batches can be ensured; the bottom of the optical detection channel is connected to a sorting channel, and a sorting component is arranged inside the sorting channel. The sorting component is connected to an adjustable transmission part that rotates outward, and the top of the adjustable transmission part is connected to the transmission connecting part. The adjustable transmission part automatically controls the kinetic energy on the transmission connecting part to be transferred to the sorting component, so that the medicine bottles in the optical detection channel are classified and output according to the detection results, so as to further improve the controllable utilization and conversion of the rotational kinetic energy of the conveyor belt; The vertical-horizontal transfer mechanism is swingably arranged at one side of the output end of the sorting channel. The vertical-horizontal transfer mechanism includes an adsorption transfer member at the bottom and a toggle member at the top. The adsorption transfer member is used to transfer the qualified medicine bottles output from the sorting channel to the input end of the output belt by adsorption. The toggle member uses the kinetic energy of the adsorption transfer member when it rotates to quickly push the medicine bottles onto the output belt, thereby controlling the qualified medicine bottles to be automatically output after vertical transfer; Among them, the medicine bottles to be inspected are placed on the conveyor belt in sequence, and then the conveyor belt is started to transport at the required speed. As the conveyor belt rotates, the medicine bottles are intermittently transferred and fall into the feeding channel in the intermittent feeding platform. At this time, under the action of the transmission connecting parts, the intermittent unloading components are controlled to drive the medicine bottles to enter the optical inspection channel in sequence. The medicine bottles pass through the optical inspection channel longitudinally for optical inspection, and then fall into the sorting channel. At this time, the adjustable transmission component automatically controls the sorting component to separate qualified products from defective products and output them according to the inspection results of the medicine bottles. For the qualified products output, the adsorption transfer part and the toggle part are started at this time. The adsorption transfer part transfers the qualified medicine bottles to the input end of the output belt. When it rotates, it drives the toggle part to push the medicine bottles onto the output belt for output, thereby realizing the operation mode of automatic and efficient transfer and optical inspection of the medicine bottles.

[0006] Compared with the prior art, the beneficial effects of the present invention are as follows: by setting a group of optical detection channels and vertical-horizontal transfer mechanisms between the conveyor belt and the output belt, and then under the action of the transmission connector and the adjustable transmission member, the medicine bottles on the conveyor belt are controlled to be intermittently transferred to the optical detection channel, and at the same time, a group of intermittent feeding platforms that feed synchronously with the conveyor belt are set on the top of the optical detection channel. The intermittent feeding platform fully utilizes the running kinetic energy of the conveyor belt, improves the energy conversion utilization rate, and ensures that the feeding speed in the optical detection channel changes positively with the conveying speed of the conveyor belt, thereby ensuring the speed and efficiency of optical detection of medicine bottles in the optical detection channel; By setting a normal product output channel and a defective product output channel at the bottom of the optical inspection channel, and using a sorting component to control the automatic classification and output of medicine bottles, and a controlled connection between the sorting component and the conveyor belt, the utilization of the conveyor belt's running kinetic energy is further improved, and the controllability is improved, thereby ensuring the accurate output of the medicine bottles after inspection; By setting a vertical-horizontal transfer mechanism at the end of the normal product output channel, the tested medicine bottles are transferred to the output belt again at a vertical angle for output, ensuring subsequent normal and smooth operation.

[0025] See also Figure 1-Figure 4 A medicine bottle detection device based on optical principles includes a U-shaped base 10, the top ends of the U-shaped base 10 extend outwards to form a running frame of the entire medicine bottle detection device, and a conveyor belt 11 and an output belt 12 are respectively arranged on both sides of the top of the U-shaped base 10 for inputting medicine bottles to be detected and outputting qualified medicine bottles after detection; An optical detection channel 15 is arranged below the output end of the conveyor belt 11, and is used for mobile optical detection of medicine bottles falling on and off the conveyor belt 11. An intermittent feeding platform 16 is arranged at the top of the optical detection channel 15. The top of the intermittent feeding platform 16 extends to the output end of the conveyor belt 11, and is used for receiving medicine bottles falling intermittently in the longitudinal direction. The intermittent feeding platform 16 includes a feeding channel which is opened at the center and runs through the top and bottom. An intermittent unloading component is arranged inside the feeding channel. The intermittent unloading component controls the automatic cyclic falling of medicine bottles. One side of the intermittent unloading component is rotatably connected to the driving shaft 50 on the conveyor belt 11 through a transmission connecting piece, and the transmission connecting piece is used to transfer part of the rotational kinetic energy of the conveyor belt 11 to the intermittent unloading component, thereby controlling the unloading of medicine bottles from the output. The medicine bottles outputted from the conveyor belt 11 are transferred to the optical detection channel 15 for detection, that is, the speed of the medicine bottles entering the optical detection channel 15 is positively changed with the conveying speed of the medicine bottles on the conveyor belt 11, so that the kinetic energy can be effectively utilized while ensuring the efficient detection of medicine bottles of different batches; the bottom of the optical detection channel 15 is connected to the sorting channel 39, and a sorting component is arranged inside the sorting channel 39. The sorting component is connected to an adjustable transmission part that rotates outward, and the top of the adjustable transmission part is connected to the transmission connecting part. The adjustable transmission part automatically controls the kinetic energy on the transmission connecting part to be transferred to the sorting component, so that the medicine bottles are classified and output according to the detection results of the medicine bottles in the optical detection channel 15, so as to further improve the controllable utilization and conversion of the rotational kinetic energy of the conveyor belt 11; The vertical-horizontal transfer mechanism 14 is swingably arranged at one side of the output end of the sorting channel 39. The vertical-horizontal transfer mechanism 14 includes an adsorption transfer member at the bottom and a toggle member at the top. The adsorption transfer member is used to transfer the qualified medicine bottles output from the sorting channel 39 to the input end of the output belt 12 by adsorption. The toggle member uses the kinetic energy of the adsorption transfer member when it rotates to quickly push the medicine bottles onto the output belt 12, so as to control the qualified medicine bottles to be automatically output after vertical transfer. Among them, the medicine bottles to be inspected are placed on the conveyor belt 11 in sequence, and then the conveyor belt 11 is started to transport at the required speed. As the conveyor belt 11 rotates, the medicine bottles are intermittently transferred and fall into the feeding channel in the intermittent feeding platform 16. At this time, under the action of the transmission connecting parts, the intermittent unloading components are controlled to drive the medicine bottles to enter the optical detection channel 15 in sequence. The medicine bottles pass through the optical detection channel 15 longitudinally for optical detection, and then fall into the sorting channel 39. At this time, the adjustable transmission component automatically controls the sorting component to separate qualified products from defective products and output them according to the inspection results of the medicine bottles.

When it rotates, it drives the toggle part to push the medicine bottles onto the output belt 12 for output, thereby realizing the operation mode of automatic and efficient transfer and optical detection of medicine bottles.

[0026] In the embodiment of the present invention, two sets of drive shafts 50 are rotatably arranged at both ends of the conveyor belt 11 and the output belt 12, and the ends of the drive shafts 50 are fixed on the U-shaped base 10 through support sleeves; Fig. 9 The lower side of the sorting channel 39 is connected with an inclined normal product output channel 40 and a defective flat output channel 41, respectively. The normal product output channel 40 is distributed toward one side of the vertical-horizontal transfer mechanism 14, and the bottom end of the defective flat output channel 41 is connected with a vertical drop tube. A defective product collection box 13 for receiving defective medicine bottles is arranged on the U-shaped base 10 below the drop tube. The bottom end of the normal product output channel 40 is connected with a horizontal stagnation channel 48 distributed horizontally. The connection between the horizontal stagnation channel 48 and the defective flat output channel 41 is provided with an arc-shaped smooth structure, which is used to control the medicine bottle to smoothly adjust the direction and slide to the horizontal stagnation channel 48, that is, to stay horizontally on the horizontal stagnation channel 48, and then the bottom surface of the bottle is adsorbed by the adsorption transfer member, and when it is transferred to the input end of the output belt 12, it enters the output belt 12 at a vertical angle; Specifically, a slip-resistant belt is provided on the surface of the horizontal stagnation channel 48, and the slip-resistant belt controls the end of the medicine bottle to stay stably at the end of the horizontal stagnation channel 48; The top of the feed channel is connected to a feed hopper 18. After the medicine bottles falling along the output end of the conveyor belt 11 fall into the feed hopper 18, they are vertically straightened and then enter the feed channel. See also Figure 8 The optical detection channel 15 is set to an inverted truncated cone structure. A plurality of optical sensors 36 are installed at equal intervals in a ring on the inner side of the optical detection channel 15. The optical sensors 36 perform all-round scanning and detection on the medicine bottles passing vertically along the inside of the optical detection channel 15. An image processing system 38 is installed on the outer side of the optical detection channel 15. The image information collected by the optical sensor 36 is transmitted to the image processing system 38 in real time for analysis and processing. At the same time, a plurality of LED light source rods 37 with increasing radial lengths from top to bottom are evenly installed on the inner wall of the optical detection channel 15. The LED light source rods 37 are distributed to form a V-shaped channel in the middle, in which only a single medicine bottle can pass vertically. That is, the LED light source rods 37 are used to provide sufficient light for the optical sensor 36 while keeping the medicine bottle falling smoothly along the inside of the optical detection channel 15. The LED light source rod 37 is made of a transparent rubber material, and an LED light strip is arranged inside it, which can maintain the brightness while reducing the degree of collision damage when the medicine bottle contacts the LED light source rod 37; It should be noted that the cooperation between the optical sensor 36, the LED light source rod 37 and the image processing system 38 is used in the following application scenarios for the detection of medicine bottles: Crack detection: Principle: An optical sensor 36 is used to capture an image of the surface of the medicine bottle, and an image processing system 38 is used to identify cracks.

[0034] In one embodiment of the present invention, see Figure 1 , Figure 5-Figure 7 , Fig.10 The intermittent unloading assembly includes an upper rotating drive plate 21 and a lower fixed base plate 22 which are longitudinally parallel and spaced apart. The upper rotating drive plate 21 and the lower fixed base plate 22 are arranged in a circular structure. The feeding channel passes through the center of the upper rotating drive plate 21 and the lower fixed base plate 22 and is downwardly connected to the top of the optical detection channel 15. A rotating slide bar 23 with a non-full circle length and located outside the feeding channel is installed in the middle of the top of the upper rotating drive plate 21.

When the return spring 25 is in a free state, the end of the rotating slide 23 is controlled to be away from the partition block. When the conveyor belt 11 is running, under the action of the transmission connection, the rotating slide 23 is intermittently driven to squeeze the return spring 25, and the unloading channel is opened in turn. After the extrusion of the rotating slide 23 is lost, the unloading channel is automatically closed by utilizing the resilience of the rotating slide rail 24; A plurality of swing baffles 20 with contact connection and the same quadrilateral structure are arranged in a circular swing between the upper rotating drive plate 21 and the lower fixed base plate 22. The side walls of adjacent swing baffles 20 are in contact and swing, and the same sharp corner of each swing baffle 20 can swing to the center of the material discharge channel at the same time to block it. When swinging in the opposite direction, the sharp corner moves away from the center until the material discharge channel is opened. A swing waist-shaped chute 30 is provided on each group of swing baffles 20. The two ends of the swing waist-shaped chute 30 are slightly biased to the two corners of the swing baffles 20 distributed along the radial direction. A positioning rod 31 is rotatably arranged inside the positioning rod 31. One end of the positioning rod 31 moves toward the lower fixed base plate 22 and passes through the lower fixed base plate 22 and is positioned by the lower fixed base plate 22. The other end is spaced apart from the upper rotating drive plate 21. A stationary arc is provided on the lower fixed base plate 22 near the outer corner of the swing baffle 20. shaped slot 29, a rotating drive rod 27 is swingably arranged inside the static arc slot 29, the end of the rotating drive rod 27 is fixed on the swing baffle 20, and extends into the radial opening slot 26 provided on the upper rotating drive plate 21. When the upper rotating drive plate 21 rotates, the rotating drive rod 27 is subjected to the rotation thrust of the radial opening slot 26, and at this time, the swing baffle 20 is driven to swing synchronously, and at this time, the rotating drive rod 27 also swings in the static arc slot 29, and then the positioning rod 31 is subjected to the rotation thrust of the swing waist slot 30, and the movable limit rotation between the positioning rod 31 and the lower fixed base plate 22 is utilized to control the contact swing between the side walls of the swing baffle 20, thereby controlling the closing of the material discharge channel, and after the upper rotating drive plate 21 loses the rotation thrust, the rebound force of the rotary spring 25 is utilized to control the swing baffles 20 to swing and separate, thereby closing the material discharge channel; Specifically, an incomplete gear ring 28 is installed on the circumferential outer wall of the upper rotating drive plate 21 facing the conveyor belt 11, and the incomplete gear ring 28 is intermittently meshed with the transmission connection member to control the intermittent rotation of the upper rotating drive plate 21, thereby realizing the intermittent opening and closing of the unloading channel; Specifically, since the output end of the conveyor belt 11 extends to one side above the intermittent feeding platform 16, in order to maintain its stability, the driving shaft 50 at one end close to the intermittent feeding platform 16 is positioned and connected to the fixed plate 17 through a fixing rod 49.

[0035] As a preferred embodiment of the present invention, refer to Figure 1 , Fig.13The transmission connection includes an incomplete drive spur gear 32 intermittently meshed with the incomplete gear ring 28, a gear shaft is fixedly installed in the middle of the incomplete drive spur gear 32, the bottom of the gear shaft is fixed on the optical detection channel 15 through a supporting sleeve rod, and a bevel gear I 33 is connected to the upper part of the gear shaft, and an even bevel gear II 34 is vertically meshed on one side of the bevel gear I 33. A gear rod is installed at the center of the bevel gear II 34, and the gear rod is rotatably connected to the driving shaft 50 on one side of the conveyor belt 11 through the main transmission belt 35. That is, under the transmission of the main transmission belt 35, the meshing of the bevel gear II 34 and the bevel gear I 33 drives the incomplete drive spur gear 32 and the conveyor belt 11 to rotate in the positive direction, thereby driving the radial opening chute 26 to rotate synchronously, so as to realize the function of synchronously changing the feeding speed of the medicine bottle and the conveying speed of the conveyor belt 11.

[0036] As a preferred embodiment of the present invention, refer to Figure 2 , Fig. 9 The sorting assembly includes a sorting swing plate 42 swingably arranged at the top of the normal product output channel 40 and the defective flat output channel 41. The sorting swing plate 42 is rotatably connected to the bottom of the sorting channel 39 through a rotating shaft 43. The rotating shaft 43 is controlled to drive the sorting swing plate 42 to swing, so as to control the opening and closing of the normal product output channel 40 and the defective flat output channel 41. A shaft is connected to one end of the rotating shaft 43, and the shaft is connected to the adjustable transmission member outwardly, that is, according to the detection result of the medicine bottle in the optical detection channel 15, the adjustable transmission member is controlled to control the rotation of the rotating shaft 43 to adjust the swing position of the sorting swing plate 42; The adjustable transmission member includes an auxiliary transmission belt 44 rotatably connected to the shaft, the end of the auxiliary transmission belt 44 is connected to a bevel gear III 45, a group of bevel gears IV 46 is movably meshed above the bevel gear III 45, the top of the bevel gear IV 46 is connected to an electric telescopic rod 47, the top of the electric telescopic rod 47 is fixed on the optical detection channel 15, the electric telescopic rod 47 is electrically connected to the image processing system 38, the electric telescopic rod 47 receives the detection result of the medicine bottle in the image processing system 38, thereby controlling its operation or not, thereby accurately controlling the falling path of the medicine bottle; It should be noted that, under normal circumstances, the number of qualified medicine bottles is greater than the number of defective products. Therefore, a clockwork spring is arranged at the inner end of the rotating shaft 43. When the clockwork spring is in a free state, the sorting swing plate 42 is controlled to swing to the top side of the defective flat output channel 41, that is, the normal product output channel 40 is kept in a normally open state. Once a defective product is detected, the electric telescopic rod 47 is started in time to drive the bevel gear IV 46 to engage with the bevel gear III 45, and then the rotating shaft 43 is driven to rotate, and the sorting swing plate 42 is swung to the defective flat output channel 41, so as to open the normal product output channel 40. After the defective product falls, the electric telescopic rod 47 moves back, and under the rebound force of the clockwork spring, the sorting swing plate 42 rotates to the upper side of the defective flat output channel 41.

[0037] As a preferred embodiment of the present invention, refer to Figure 1 , Figure 2 , Fig.11 , Fig.12 The adsorption transfer member includes a rotating rod Ⅰ52 rotatably arranged on the fixed plate 17 near the end of the output belt 12, one end of the rotating rod Ⅰ52 is connected to a transfer motor 51, one side of the transfer motor 51 is fixed on the fixed plate 17, and the transfer motor 51 drives the rotating rod Ⅰ52 to swing, and two swing rods Ⅰ53 are symmetrically installed at both ends of the rotating rod Ⅰ52 obliquely downward, and a rotating rod Ⅱ54 is connected between the bottom ends of the two swing rods Ⅰ53, and a transfer rod 55 is vertically passed through the middle of the rotating rod Ⅱ54, and a rotating rod Ⅲ57 parallel to the transfer rod 55 is rotatably connected at one end of the transfer rod 55 near the output belt 12, and swing rods Ⅱ56 are symmetrically rotatably connected at both ends of the rotating rod Ⅲ57, and the bottom end of the swing rod Ⅱ56 is rotatably connected to a support rod fixed on the U-shaped base 10, and the swing rod When I53 is driven by the rotation of the rotating rod I52, the rotating rod II54 is driven to control the end of the transfer rod 55 away from the output belt 12 to rotate upward in an arc shape. At this time, the end of the swing rod II56 away from the support column is swung upward obliquely until the end of the transfer rod 55 away from the output belt 12 is swung to the input end of the output belt 12. When the transfer motor 51 rotates in the reverse direction, the above structure is controlled to move in the reverse direction. The end of the transfer rod 55 away from the output belt 12 is installed with a suction cup substrate 58, and the end of the suction cup substrate 58 is installed with a suction cup 59. When the transfer rod 55 is at the lowest point, the suction cup 59 is controlled to be at a vertical angle and located at the end of the horizontal stagnation channel 48, that is, the suction force of the suction cup 59 is used to adsorb the medicine bottle placed horizontally on the horizontal stagnation channel 48 until it is transferred to the input end of the output belt 12. The toggle member includes a push plate base 60 fixedly mounted in the middle of the rotating rod Ⅰ52, and a vertical push plate 61 is mounted at the end of the push plate base 60. When the transfer motor 51 controls the rotating rod Ⅰ52 to rotate and drives the medicine bottle to transfer toward the input end of the output belt 12, the push plate 61 swings away in an arc relative to the direction of the output belt 12. When the transfer motor 51 moves back in the reverse direction, the push plate 61 is synchronously driven to move back, and at this time, the medicine bottle adsorbed on the suction cup 59 is quickly pushed onto the output belt 12; It should be noted that the adsorption force of the suction cup 59 on the medicine bottle is much lower than the lateral thrust of the push plate 61 on the medicine bottle, that is, while maintaining the suction cup 59 to stably adsorb and transfer the medicine bottle, the push plate 61 is controlled to safely and stably transfer the medicine bottle to the output belt 12. The start and stop of the suction cup 59 can also be controlled by timing to control whether the medicine bottle is adsorbed or not, thereby ensuring that the adsorption force on the medicine bottle and the pushing force of the push plate 61 cooperate with each other.

[0038] The working principle of the present invention is: in the idle position of the device, all the driving parts mentioned above, which refer to power elements, electrical components and adapted power supplies, are connected through wires, and the electrical connections are completed in a working order. The detailed connection means are well-known technologies in the field. The following mainly introduces the working principle and process, and does not explain the electrical control. During operation, the medicine bottles to be detected are placed on the conveyor belt 11 at equal intervals, and then the conveyor belt 11, the output belt 12 and the optical sensor 36, the LED light source rod 37, the image processing system 38 and other components inside the optical detection channel 15 are started. With the transmission of the LED light source rod 37, the medicine bottles fall into the feed funnel 18 in turn. At this time, under the transmission of the main transmission belt 35, the bevel gear II 34 and the bevel gear I 33 are driven to rotate in meshing, and then the incompletely driven spur gear 32 is controlled to drive the radial opening slide 26 to rotate intermittently, so as to control the intermittent opening of the feed channel and control the medicine bottles to enter the optical detection channel. Optical inspection is performed inside the channel 15. After the medicine bottle for vertical drop inspection enters the sorting channel 39, the electric telescopic rod 47 controls the electric telescopic rod 47 to extend according to the detection result of the image processing system 38. If it is a qualified product, the electric telescopic rod 47 does not operate. At this time, the medicine bottle is output to the horizontal stagnation channel 48 along the normal product output channel 40, and then the transfer motor 51 is started to drive the rotating rod I 52 to rotate, thereby controlling the suction cup 59 to adsorb the medicine bottle, and then under the action of the swing rod I 53, the rotating rod II 54, the transfer rod 55, the swing rod II 56 and other structures, it is transferred to the input end of the output belt 12, and then when the rotating rod I 52 rotates, the push plate 61 is controlled to push it into the output belt 12 for output. If it is a defective product, the electric telescopic rod 47 operates to control the bevel gear IV 46 to mesh with the bevel gear III 45, and then drives the sorting swing plate 42 to open the top of the defective flat output channel 41, so as to output it along the defective flat output channel 41 to the defective product collection box 13.

[0039] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
