Description

Technical Field

[0001] This invention relates to the field of medicine bottle detection technology, specifically a medicine bottle detection device based on optical principles. Background Technology

[0002] An optically based medicine bottle inspection device is a device that uses optical technology to inspect the quality and integrity of medicine bottles. This device is commonly used in the pharmaceutical industry to ensure that medicine bottles are free of defects such as cracks, foreign objects, and uneven seals during filling, sealing, and packaging.

[0003] Existing optical-based medicine bottle inspection devices suffer from insufficient overall coordination when inspecting medicine bottles on mass production lines. This is mainly reflected in the 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. Furthermore, the energy transfer between the above steps lacks effective linkage, resulting in low overall energy conversion and utilization rate and affecting operational efficiency.

[0004] Therefore, in view of the above-mentioned problems, this technical solution proposes a medicine bottle detection device based on optical principles. Summary of the Invention

[0005] The purpose of this invention is to provide a medicine bottle detection device based on optical principles to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a medicine bottle detection device based on optical principles, comprising a U-shaped base, with both ends of the top of the U-shaped base extending outward to form the operating frame of the entire medicine bottle detection device; and conveyor belts and output belts respectively provided on both sides of the top of the U-shaped base for inputting medicine bottles to be detected and outputting qualified medicine bottles after detection.

[0007] An optical inspection channel, located below the conveyor belt output end, is used for mobile optical inspection of medicine bottles falling up and down the conveyor belt. An intermittent feeding platform is connected to the top of the optical inspection channel, extending to the conveyor belt output end to receive the intermittently falling medicine bottles. The intermittent feeding platform includes a feeding channel running vertically through its center. An intermittent feeding component is installed inside the feeding channel, controlling the automatic cyclical descent of medicine bottles. One side of the intermittent feeding component is rotatably connected to the drive shaft on the conveyor belt via a transmission connector. The transmission connector transfers part of the rotational kinetic energy of the conveyor belt to the intermittent feeding component, thereby controlling the descent of medicine bottles from the conveyor belt. The medicine bottles output from the upper part are transferred to the optical detection channel for inspection. The speed of the medicine bottles entering the optical detection channel changes in the same direction as the conveyor belt speed, which not only makes efficient use of kinetic energy but also ensures efficient inspection of different batches of medicine bottles. The bottom of the optical detection channel is connected to a sorting channel, which is equipped with sorting components. The sorting components are rotated outward and connected to an adjustable transmission component. The top of the adjustable transmission component is connected to a transmission connector. The adjustable transmission component automatically controls the transfer of kinetic energy from the transmission connector to the sorting component. Based on the inspection results of the medicine bottles in the optical detection channel, they are sorted and output, further improving the controllable utilization and conversion of the rotating kinetic energy of the conveyor belt.

[0008] The vertical-horizontal transfer mechanism is oscillatingly set on one side of the sorting channel output end. The vertical-horizontal transfer mechanism includes a bottom adsorption transfer component and a top actuating component. The adsorption transfer component is used to adsorb and transfer qualified medicine bottles output from the sorting channel to the output belt input end. The actuating component uses the kinetic energy of the adsorption transfer component when it rotates to quickly push the medicine bottle onto the output belt, thereby controlling the qualified medicine bottles to be automatically output after vertical transfer.

[0009] In this process, the medicine bottles to be inspected are placed sequentially on a conveyor belt, which is then started to transport them at the required speed. As the conveyor belt rotates, the medicine bottles are intermittently transferred and fall into the feeding channel of the intermittent feeding platform. At this time, under the action of the transmission connector, the intermittent feeding component is controlled to drive the medicine bottles sequentially into the optical inspection channel. 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 according to the inspection results. For the qualified products, the adsorption transfer component and the agitator are activated. The adsorption transfer component transfers the qualified medicine bottles to the input end of the output belt. When it rotates, it drives the agitator to push the medicine bottles onto the output belt for output. This realizes the operation mode of automated and efficient transfer and optical inspection of medicine bottles.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: by setting up an optical detection channel and a vertical-horizontal transfer mechanism between the conveyor belt and the output belt, and then controlling the intermittent transfer of medicine bottles on the conveyor belt to the optical detection channel under the action of the transmission connector and the adjustable transmission component, a set of intermittent feeding platforms that follow the synchronous changes of the conveyor belt are set up at the top of the optical detection channel. The intermittent feeding platform makes full use of the running kinetic energy of the conveyor belt, improves the energy conversion and utilization rate, and ensures that the feeding speed in the optical detection channel changes positively with the conveying speed of the conveyor belt, thus ensuring the speed and efficiency of optical detection of medicine bottles in the optical detection channel.

[0011] By setting up normal product output channels and defective product output channels at the bottom of the optical inspection channel, and by using sorting components to control the automatic classification and output of medicine bottles, and by controlling the connection between the sorting components and the conveyor belt, the utilization of the kinetic energy of the conveyor belt is further improved, and the controllability is enhanced, ensuring the accurate output of medicine bottles after inspection.

[0012] By setting a vertical-horizontal transfer mechanism at the end of the normal product output channel, the tested medicine bottles are transferred back to the output belt at a vertical angle, ensuring smooth and normal operation afterwards. Attached Figure Description

Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0029] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] Please see Figures 1-4 A medicine bottle detection device based on optical principles includes a U-shaped base 10. The top two ends of the U-shaped base 10 extend outward to form the operating frame of the entire medicine bottle detection device. Conveyor belts 11 and output belts 12 are respectively provided on the top two sides of the U-shaped base 10 for inputting medicine bottles to be detected and outputting qualified medicine bottles after detection.

[0032] An optical detection channel 15, located below the output end of the conveyor belt 11, is used for moving optical detection of medicine bottles falling up and down on the conveyor belt 11. An intermittent feeding platform 16 is connected to the top of the optical detection channel 15, extending to the output end of the conveyor belt 11. This intermittent feeding platform 16 receives medicine bottles falling longitudinally and intermittently. The intermittent feeding platform 16 includes a feeding channel extending vertically through its center. An intermittent feeding component is installed inside the feeding channel. This component controls the automatic cyclical falling of medicine bottles. One side of the intermittent feeding component is rotatably connected to the drive shaft 50 on the conveyor belt 11 via a transmission connector. The transmission connector transfers part of the rotational kinetic energy of the conveyor belt 11 to the intermittent feeding component, thereby controlling the flow of medicine bottles from the conveyor belt 11. The medicine bottles output 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 changes in the same direction as the conveying speed of the medicine bottles on the conveyor belt 11, so as to realize the effective utilization of kinetic energy and ensure efficient detection of different batches of medicine bottles. The bottom of the optical detection channel 15 is connected to the sorting channel 39. The sorting channel 39 is equipped with a sorting component. The sorting component is rotated outward and connected to an adjustable transmission component. The top of the adjustable transmission component is connected to a transmission connector. The adjustable transmission component automatically controls the kinetic energy on the transmission connector to be transferred to the sorting component. Based on the detection results of the medicine bottles in the optical detection channel 15, they are sorted and output, further improving the controllable utilization and conversion of the rotational kinetic energy of the conveyor belt 11.

[0033] The vertical-horizontal transfer mechanism 14 is oscillatingly set on one side of the output end of the sorting channel 39. The vertical-horizontal transfer mechanism 14 includes a bottom adsorption transfer member and a top actuating member. The adsorption transfer member is used to adsorb and transfer qualified medicine bottles output from the sorting channel 39 to the input end of the output belt 12. The actuating member uses the kinetic energy of the adsorption transfer member when it rotates to quickly push the medicine bottle onto the output belt 12, thereby controlling the qualified medicine bottles to be automatically output after vertical transfer.

[0034] In this process, the medicine bottles to be inspected are placed sequentially on the conveyor belt 11, and then the conveyor belt 11 is started to transport the medicine bottles at the required speed. As the conveyor belt 11 rotates, the medicine bottles are intermittently transferred and fall into the feeding channel of the intermittent feeding platform 16. At this time, under the action of the transmission connector, the intermittent feeding component is controlled to drive the medicine bottles into the optical inspection channel 15 sequentially. The medicine bottles pass through the optical inspection channel 15 longitudinally for optical inspection, 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 according to the inspection results. For the qualified products, the adsorption transfer component and the agitator are activated. The adsorption transfer component transfers the qualified medicine bottles to the input end of the output belt 12. When it rotates, it drives the agitator to push the medicine bottles onto the output belt 12 for output, thereby realizing the operation mode of automated and efficient transfer and optical inspection of medicine bottles.

[0035] In this embodiment of the invention, two sets of drive shafts 50 are rotatably provided at both ends of the conveyor belt 11 and the output belt 12, and the ends of the drive shafts 50 are fixed to the U-shaped base 10 by support sleeves; see reference Figure 9 The lower side of the sorting channel 39 is connected to the inclined normal product output channel 40 and the defective flat output channel 41. The normal product output channel 40 is distributed towards the vertical-horizontal transfer mechanism 14. The bottom end of the defective flat output channel 41 is connected to a vertical drop tube. A defective product collection box 13 for receiving defective medicine bottles is set on the U-shaped base 10 below the drop tube. The bottom end of the normal product output channel 40 is connected to a horizontally distributed horizontal stagnation channel 48. The connection between the horizontal stagnation channel 48 and the defective flat output channel 41 is provided with an arc-shaped smooth structure to control the smooth adjustment of the medicine bottle's direction and slide onto the horizontal stagnation channel 48, that is, to place it horizontally onto the horizontal stagnation channel 48. Then, the bottom surface of the medicine bottle is adsorbed by the adsorption transfer component and transferred to the input end of the output belt 12, where it enters the output belt 12 at a vertical angle.

[0036] Specifically, the surface of the horizontal stopping channel 48 is provided with an anti-slip strip, which controls the end of the medicine bottle to stop smoothly at the end of the horizontal stopping channel 48;

[0037] The top of the feeding channel is connected to a feeding funnel 18. After the medicine bottles falling along the output end of the conveyor belt 11 fall into the feeding funnel 18, they are vertically aligned and then enter the feeding channel.

[0038] See Figure 8 The optical detection channel 15 is configured as an inverted frustum-shaped structure. Multiple sets 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 detection of the medicine bottle that passes 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 sensors 36 is transmitted to the image processing system 38 in real time for analysis and processing. At the same time, multiple sets of LED light source bars 37 with radial lengths increasing from top to bottom are evenly installed on the inner wall of the optical detection channel 15. The distribution of the LED light source bars 37 forms a V-shaped channel in the middle that allows only a single medicine bottle to pass vertically. That is, the LED light source bars 37 provide sufficient light for the optical sensors 36 while ensuring that the medicine bottle falls smoothly along the inside of the optical detection channel 15.

[0039] The LED light source bar 37 is made of transparent rubber material and has an LED light strip inside. This maintains brightness while reducing the degree of collision damage when the medicine bottle comes into contact with the LED light source bar 37.

[0040] It should be noted that the operational coordination between the optical sensor 36, the LED light source 37, and the image processing system 38 is applied to the detection of medicine bottles in the following scenarios: Crack detection:

[0041] Principle: The optical sensor 36 captures an image of the surface of the medicine bottle, and the image processing system 38 identifies the cracks.

[0042] Application: To ensure that medicine bottles do not break due to cracks during transportation and use.

[0043] Foreign object detection:

[0044] Principle: The optical sensor 36 captures images of the inside of the medicine bottle to detect the presence of foreign objects.

[0045] Application: Ensure the inside of the medicine bottle is clean and free of foreign matter contamination.

[0046] Sealing inspection:

[0047] Principle: The optical sensor 36 is used to detect the integrity and uniformity of the medicine bottle seal.

[0048] Application: To ensure that medicine bottles are sealed tightly to prevent leakage or contamination of medicines.

[0049] Tag detection:

[0050] Principle: The optical sensor 36 is used to detect the position, integrity and readability of the medicine bottle label.

[0051] Application: To ensure that the information on medicine bottle labels is accurate and complies with regulatory requirements.

[0052] In one embodiment of the present invention, see [reference] Figure 1 , Figures 5-7 , Figure 10The intermittent feeding assembly includes an upper rotating drive plate 21 and a lower fixed base plate 22 arranged longitudinally parallel to each other. The upper rotating drive plate 21 and the lower fixed base plate 22 are circular structures. The feeding channel passes through the center of the upper rotating drive plate 21 and the lower fixed base plate 22 and communicates downward with the top of the optical detection channel 15. A non-circular section of rotating slide bar 23 is installed at the top center of the upper rotating drive plate 21 and is located outside the feeding channel. A rotating slide rail 24 is rotatably connected to the top of the rotating slide bar 23. A partition block is installed inside the rotating slide rail 24 to divide the rotating slide rail 24 into a non-circular structure. The top side of the rotating slide rail 24 is connected to the conveyor belt 11 and the output belt 1 by a fixing rod. The fixed plate 17 between 2 has one side of the fixed plate 17 positioned on the U-shaped base 10 by a fixed rod. A rotary spring 25 with an arc structure is provided between one end of the rotary slide bar 23 and the partition block in the rotary slide rail 24. One end of the rotary spring 25 is connected to the rotary slide bar 23 and the other end is connected to the partition block. When the rotary spring 25 is in a free state, it controls the end of the rotary slide bar 23 to move away from the partition block. When the conveyor belt 11 is running, under the action of the transmission connector, the rotary slide bar 23 is intermittently driven to squeeze the rotary spring 25, thereby opening the feeding channel in sequence. After the squeezing of the rotary slide bar 23 is lost, the feeding channel is automatically closed by the rebound force of the rotary slide rail 24.

[0053] Multiple swing baffles 20 with identical quadrilateral structures are arranged in a ring-shaped manner between the upper rotating drive plate 21 and the lower fixed base plate 22. Adjacent swing baffles 20 swing in contact with each other, and a common sharp corner of each swing baffle 20 can simultaneously swing to block the center of the feeding channel. When swinging in the opposite direction, the sharp corner moves away from the center until the feeding channel is opened. Each set of swing baffles 20 has a swing waist-shaped groove 30. The two ends of the swing waist-shaped groove 30 are slightly offset from the two corners of the radially distributed swing baffles 20. A positioning rod 31 is rotatably installed inside the swing waist-shaped groove 30. One end of the positioning rod 31 facing the lower fixed base plate 22 moves through the lower fixed base plate 22 and is positioned by the lower fixed base plate 22, while the other end is spaced apart from the upper rotating drive plate 21. A stationary baffle is provided on the lower fixed base plate 22 near the outer corner of the swing baffle 20. The arc-shaped chute 29 has a rotating drive rod 27 inside. The end of the rotating drive rod 27 is fixed to the swing baffle 20 and extends into the radially open chute 26 opened on the upper rotating drive plate 21. When the upper rotating drive plate 21 rotates, the rotating drive rod 27 is subjected to the rotational thrust of the radially open chute 26, which drives the swing baffle 20 to swing synchronously. At this time, the rotating drive rod 27 also swings in the arc-shaped chute 29. Then, the positioning rod 31 is subjected to the rotational thrust of the swing waist-shaped chute 30, and the movable limit rotation between the positioning rod 31 and the lower fixed base plate 22 is used to control the contact swing between the side walls of the swing baffle 20, thereby controlling the closure of the feeding channel. After the upper rotating drive plate 21 loses the rotational thrust, the rebound force of the rotary spring 25 is used to control the swing baffle 20 to swing and separate, thereby closing the feeding channel.

[0054] Specifically, an incomplete gear ring 28 is installed on the circumferential outer wall of the upper rotary drive plate 21 facing the conveyor belt 11. The incomplete gear ring 28 intermittently meshes with the transmission connector to control the upper rotary drive plate 21 to rotate intermittently, thereby realizing the intermittent opening and closing of the feeding channel.

[0055] 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 drive shaft 50 at one end near the intermittent feeding platform 16 is positioned and connected to the fixed plate 17 by a fixing rod 49.

[0056] As a preferred embodiment of the present invention, see [reference]. Figure 1 , Figure 13The transmission connection includes an incompletely driven spur gear 32 that intermittently meshes with the incompletely driven gear ring 28. A gear shaft is fixedly installed in the middle of the incompletely driven spur gear 32. The bottom of the gear shaft is fixed to the optical detection channel 15 by a support sleeve. A bevel gear I 33 is connected to the upper part of the gear shaft. A bevel gear II 34 is vertically meshed on one side of the bevel gear I 33. A rack is installed at the center of the bevel gear II 34. The rack is rotatably connected to the drive shaft 50 on the conveyor belt 11 on one side through the main transmission belt 35. 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 incompletely driven spur gear 32 to rotate in the forward direction with the conveyor belt 11, thereby driving the radially open chute 26 to rotate synchronously, realizing the function of synchronously changing the feeding speed of the medicine bottle and the conveying speed of the conveyor belt 11.

[0057] As a preferred embodiment of the present invention, see [reference]. Figure 2 , Figure 9 The sorting assembly includes a sorting swing plate 42 that is oscillating at the top of the normal product output channel 40 and the defective product output channel 41. The sorting swing plate 42 is rotatably connected to the bottom of the sorting channel 39 via a rotating shaft 43. The rotating shaft 43 is controlled to drive the sorting swing plate 42 to swing, thereby controlling the opening and closing of the normal product output channel 40 and the defective product output channel 41. One end of the rotating shaft 43 is connected to a shaft rod, which is connected to an adjustable transmission component. That is, based on the detection results of the medicine bottle in the optical detection channel 15, the adjustable transmission component is controlled to control the rotation of the rotating shaft 43 and adjust the swing position of the sorting swing plate 42.

[0058] The adjustable transmission component includes an auxiliary transmission belt 44 rotatably connected to the shaft. A bevel gear III 45 is connected to the end of the auxiliary transmission belt 44. A set of bevel gears IV 46 is movably meshed above the bevel gears III 45. An electric telescopic rod 47 is connected to the top of the bevel gears IV 46. 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 results of the medicine bottle from the image processing system 38, thereby controlling whether it runs or not, so as to accurately control the falling path of the medicine bottle.

[0059] It should be noted that, under normal circumstances, the number of qualified medicine bottles exceeds the number of defective products. Therefore, a spring is installed at the inner end of the rotating shaft 43. When the spring is in a free state, it controls the sorting swing plate 42 to swing to the top side of the defective product output channel 41, thus keeping the normal product output channel 40 in a normally open state. Once a defective product is detected, the electric telescopic rod 47 is activated in time to drive the bevel gear IV 46 to mesh with the bevel gear III 45, and then drive the rotating shaft 43 to rotate, swinging the sorting swing plate 42 to the defective product output channel 41, thereby opening 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 spring, the sorting swing plate 42 rotates back to the top side of the defective product output channel 41.

[0060] As a preferred embodiment of the present invention, see [reference]. Figure 1 , Figure 2 , Figure 11 , Figure 12 The adsorption transfer component includes a rotating rod I 52 rotatably mounted on the fixed plate 17 near the end of the output belt 12. One end of the rotating rod I 52 is connected to a transfer motor 51, which is fixed to the fixed plate 17 on one side. The transfer motor 51 drives the rotating rod I 52 to swing. Two swing rods I 53 are symmetrically mounted diagonally downwards at both ends of the rotating rod I 52. A rotating rod II 54 is connected between the bottom ends of the two swing rods I 53. A transfer rod 55 is rotatably passed through the middle of the rotating rod II 54. A rotating rod III 57 is rotatably connected to the end of the transfer rod 55 near the output belt 12 and is parallel to it. Swing rods II 56 are rotatably connected diagonally downwards at both ends of the rotating rod III 57. A support rod fixed to the U-shaped base 10 is rotatably connected to the bottom end of the swing rod II 56. When I53 is driven by the rotation of rotating rod I52, it drives rotating rod II54 to control the end of transfer rod 55 away from output belt 12 to rotate upward in an arc. At this time, the end of swing rod II56 away from support column swings obliquely upward until the end of transfer rod 55 away from output belt 12 is swung to the input end of output belt 12. When transfer motor 51 rotates in the opposite direction, it controls the above structure to move in the opposite direction. The end of transfer rod 55 away from output belt 12 is equipped with suction cup base plate 58, and the end of suction cup base plate 58 is equipped with suction cup 59. When transfer rod 55 is at its lowest point, it controls suction cup 59 to be at a vertical angle and located at the end of horizontal stagnation channel 48. That is, the suction force of suction cup 59 is used to adsorb the medicine bottle placed horizontally on horizontal stagnation channel 48 until it is transferred to the input end of output belt 12.

[0061] The actuating component includes a push plate base 60 fixedly installed in the middle of the rotating rod I 52. A vertical push plate 61 is installed at the end of the push plate base 60. When the transfer motor 51 controls the rotating rod I 52 to rotate and drives the medicine bottle to move towards the input end of the output belt 12, the push plate 61 swings away in an arc relative to the output belt 12. When the transfer motor 51 moves back in the opposite direction, it drives the push plate 61 to move back synchronously. At this time, the medicine bottle adsorbed on the suction cup 59 is quickly pushed into the output belt 12.

[0062] It should be noted that the suction force of the suction cup 59 on the medicine bottle is much lower than the lateral pushing force of the push plate 61 on the medicine bottle. That is, while maintaining the smooth suction and transfer of the medicine bottle by the suction cup 59, the push plate 61 is controlled to safely and stably transfer the medicine bottle to the output belt 12. The suction cup 59 can also be started and stopped at a time to control whether or not it is suctioned on the medicine bottle, so as to ensure that the suction force on the medicine bottle and the pushing force of the push plate 61 work together.

[0063] The working principle of this invention is as follows: During idle periods, all the aforementioned driving components (representing power elements, electrical components, and compatible power supplies) are connected via wires. The electrical connections between these components are completed sequentially. The detailed connection methods are well-known in the field. The following mainly describes the working principle and process, without further explanation of the electrical control. During operation, the medicine bottles to be tested are placed at equal intervals on the conveyor belt 11. Then, the optical sensor 36, LED light source bar 37, image processing system 38, and other components inside the conveyor belt 11, output belt 12, and optical detection channel 15 are activated. As the LED light source bar 37 transmits the light, the medicine bottles fall sequentially into the feeding hopper 18. At this time, under the transmission of the main drive belt 35, the bevel gears II 34 and I 33 mesh and rotate, thereby controlling the partially driven spur gear 32 to drive the radially open slide groove 26 to rotate intermittently. This controls the intermittent opening of the feeding channel, controlling the medicine bottles to enter the optical detection channel. Optical inspection is performed inside channel 15. After the vertically falling medicine bottle enters the sorting channel 39, the electric telescopic rod 47 is controlled 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 along the normal product output channel 40 to the horizontal stagnation channel 48. Then, the transfer motor 51 is started to drive the rotating rod I 52 to rotate, thereby controlling the suction cup 59 to pick up the medicine bottle. Then, under the action of the swing rod I 53, rotating rod II 54, transfer rod 55, swing rod II 56 and other structures, it is transferred to the input end of the output belt 12. 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, thereby outputting it along the defective flat output channel 41 to the defective product collection box 13.

[0064] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
