[0002] In the production process of boxed liquid pharmaceutical preparations, the transmission, direction detection, and sorting adjustment of the boxes are key links. Among them, it is extremely crucial to ensure that the boxes enter the subsequent processes in the correct direction. During the visual inspection of the front and back sides of the boxes, the sorting and flipping processes play an indispensable role. From the perspective of product consistency and quality control, the packaging of boxed liquid pharmaceutical preparations has strict specifications. The front of the box usually prints key information such as product name, specification, usage instructions, etc., and the back may involve ingredient list, shelf life, production batch, etc. If the box direction is incorrect, it will lead to chaotic display of product information. In large-scale production, manually checking the box direction one by one is time-consuming and laborious, and it is difficult to ensure 100% accuracy.

[0023] See Figures 1 - 9 As shown, the present invention provides a visual inspection device for boxed liquid preparations with a forward and reverse adjustment function. The base 1 serves as a basic support component. The first conveyor 2 and the second conveyor 8 are sequentially arranged on the base 1 and are connected to each other for sequentially transporting the box body 13. Among them, the first conveyor 2 is used to transport the box body from the starting position towards the second conveyor 8. The swing support structure 4 is arranged on the lower side of the opposite end of the first conveyor 2 and the second conveyor 8, which plays a horizontal deflection support role for the first conveyor 2 and provides a support point when the first conveyor 2 is horizontally deflected. The swing drive mechanism 6 is also arranged on the base 1 and is used to drive the first conveyor 2 to deflect. The visual detector 3 is installed along the transport direction of the first conveyor 2 and is used to detect the front and back of the box body. The lateral conveyor 7 is also arranged along the transport direction of the first conveyor 2 and is used to guide the box body out. The linear drive assembly 9 is arranged on the base 1 and is connected to the second conveyor 8 for adjusting the distance between the second conveyor 8 and the first conveyor 2. The material separation partition structure 10 is arranged on the second conveyor 8 to form two collection channels. The stop structure 12 is arranged in one of the channels for collecting the forward box bodies. The forward and reverse adjustment mechanism 11 is arranged in the other channel for collecting the reverse box bodies. Through the mutual cooperation of each component, a series of automated operations such as the transport, visual inspection, guiding output of the box body, sorting on the second conveyor, adjustment of the reverse box body, and collection of the forward box body are realized, and the transport and direction adjustment work of the box body can be efficiently and accurately processed.

[0024] See the attached specification Figure 1 and Figure 2As shown in the figure, two first racks 201 are distributed in parallel, and a first conveyor belt 202 is arranged between them to achieve connection and cooperation with the two first racks 201. A first driving motor 203 is installed on one of the first racks 201, and its power output end is connected to the first conveyor belt 202 to provide power for the operation of the first conveyor belt 202. A swing support structure 4 is arranged on the lower side of the opposite end of the first conveyor 2 and the second conveyor 8. A support swing wheel structure 5 is arranged on the lower side of the connection between the first conveyor 2 and the second conveyor 8. A visual detector 3 is arranged on the upper side of the two first racks 201. Among them, the visual detector 3 uses principles such as optical imaging to collect and analyze images of the boxes transported on the first conveyor 2, judge the front and back directions of the boxes, and provide information basis for subsequent sorting and adjustment. The visual detector 3 adopts the existing technology and is well-known to those skilled in the art. The first conveyor 2 and its related components work together to achieve stable transportation of the boxes, and the visual detector 3 is used to detect the front and back directions of the boxes during the transportation process. The swing support structure 4 and the support swing wheel structure 5 cooperate to enable the first conveyor 2 to make angle adjustments when necessary to meet the working requirements of the overall equipment, laying a foundation for subsequent processes such as box sorting and adjustment.

[0025] See the attached drawings of the specification Figure 1 、 Figure 6 and Figure 7 As shown in the figure, the swing support structure 4 includes a first lower bracket 401 fixedly arranged on the lower side of the first conveyor 2. The first lower bracket 401 is fixedly provided with an upper support ear 402 and a lower support ear 403 in the vertical direction respectively. A swing support shaft 406 is arranged between the upper support ear 402 and the lower support ear 403 to provide an axis for the swing of the first conveyor 2. A fixed frame 405 is fixedly arranged on the base 1, and a fixed block 404 for supporting and rotating the swing support shaft 406 is fixedly arranged on the fixed frame 405. A first swing support wheel for rolling contact with the upper surface of the base 1 is arranged on the bottom side of the first lower bracket 401. When the first conveyor swings, it rolls and contacts with the upper surface of the base, reducing the friction when the first conveyor swings, and at the same time playing an auxiliary role in supporting the first conveyor to make the swing process smoother. The swing support structure 4 provides a stable horizontal deflection support point and a rotation axis for the first conveyor 2 through the coordinated cooperation of each component, so that the first conveyor 2 can smoothly make an angle adjustment in the horizontal direction around the swing support shaft under the action of the swing driving mechanism 6, and the first swing support wheel assists its smooth swing to meet the requirement of the overall equipment for the transmission angle adjustment of the box 2.

[0026] See the attached drawings of the specification Figure 3 and Figure 4As shown, the swing drive mechanism 6 includes a swing drive motor 601 fixed on the base 1 through a fixed seat 602, the output shaft end of the swing drive motor 601 is connected to a swing wheel 603 through a reducer, a third lower bracket 607 is arranged on the lower side of the first conveyor 2, a second hinge shaft 605 is rotatably arranged on the third lower bracket 607, a first hinge shaft 604 is rotatably arranged at the eccentric position of the swing wheel 603, an eccentric connecting rod 606 is connected between the first hinge shaft 604 and the second hinge shaft 605, and the supporting swing wheel structure 5 includes a second lower bracket 501 arranged on the lower side of the first conveyor 2, and a second swing support wheel 502 for rolling abutment with the upper surface of the base 1 is arranged on the bottom side of the second lower bracket 501. When the first conveyor 2 swings, it rolls in contact with the base 1 to assist in supporting the first conveyor 2 and reduce the swinging friction. The swing drive mechanism 6 is powered by the swing drive motor 601, and the motor rotation is converted into the swinging motion of the first conveyor 2 around the swing support shaft 406 through the transmission of the reducer, the swing wheel 603, the eccentric connecting rod 606 and other components, so as to adjust the transmission angle of the first conveyor 2; the second swing support wheel 502 assists the first conveyor 2 to swing smoothly, meeting the equipment's demand for flexible adjustment of the transmission angle of the box body 13. The whole system works in coordination, so that the box body can flexibly adjust the transmission angle according to actual needs during the transmission process, thereby improving the adaptability and work efficiency of the equipment.

[0027] See the instruction manual Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the lateral conveyor 7 is provided with two wheel base plates 701 arranged opposite to each other, each wheel base plate 701 is rotatably provided with more than four pulleys 702, and the pulleys 702 are meshed and connected with a side conveyor belt 703, a mounting frame 706 is fixedly provided on the wheel base plate 701, and a third driving motor 704 for driving one of the pulleys 702 to rotate is provided on the mounting frame 706, and a guide side plate 705 is respectively provided at one end of the two wheel base plates 701 facing the second conveyor 8, which is used to guide the box body to be transmitted in a predetermined direction, prevent the box body 13 from being offset during the transmission process, and ensure that the box body 13 can be accurately transmitted from the lateral conveyor 7 to the second conveyor 8, and push rods 709 are respectively fixedly provided on the lower sides of the two mounting frames 706, and a first electric telescopic rod 708 for driving the spacing adjustment of the two push rods 709 is provided on the lower side of the first conveyor 2. The lateral conveyor 7 realizes the function of lateral transmission of the box body from the first conveyor 2 to the second conveyor 8 through the coordinated work of various components. The third driving motor 704 drives the pulley 702 to drive the side conveyor belt 703 to operate the transmission box body, and the guide side plate 705 ensures the accurate transmission direction of the box body. The first electric telescopic rod 708 adjusts the spacing between the wheel base plates 701 to adapt to different box body sizes, meeting the equipment's requirements for diversified box body transmission and improving the working efficiency and adaptability of the entire equipment.

[0028] See the attached specification Figure 1 and Figure 2 As shown, the second conveyor 8 includes two second racks 801 distributed in parallel. A second conveyor belt 802 is arranged between the two second racks 801. A second driving motor 803 for driving the second conveyor belt 802 is arranged on one of the second racks 801. The material distribution partition structure 10 is arranged on the upper side of the second conveyor 8, and the linear driving assembly 9 is arranged on the lower side of the second conveyor 8.

[0029] See the attached specification Figure 6 As shown, the linear driving assembly 9 includes a frame 901 fixedly arranged on the base 1. More than two moving wheels 905 are rotatably arranged on the lower side of each second rack 801. A wheel groove 904 for guiding the movement of the moving wheels 905 is formed on the upper surface of the frame 901. By rolling in the wheel groove 904, the friction when the second rack 801 moves is reduced, so that the second rack 801 can move smoothly on the frame 901, playing a role in supporting and assisting the movement. A linear chute 906 is formed on the upper side of the frame 901, and a linear slider 903 is fixedly arranged on the lower side of the second rack 801. A cylinder 902 for driving the linear slider 903 to slide in the linear chute 906 is fixedly arranged on the frame 901. Through the coordinated work of each component of the linear driving assembly 9, the precise adjustment of the position of the second conveyor 8 is realized. Specifically, it is to adjust the distance between the second conveyor 8 and the first conveyor 2. The frame 901 provides a stable support and guiding foundation. The cooperation between the moving wheels 905 and the wheel groove 904 ensures that the second rack 801 moves smoothly and in the correct direction. The linear slider 903 and the linear chute 906 accurately transmit power, and the cylinder 902 serves as the power source to drive the entire adjustment process. This precise distance adjustment function enables the equipment to adapt to the transmission requirements of different-sized boxes, improving the versatility and working efficiency of the equipment, and ensuring that the transmission connection between the first conveyor 2 and the second conveyor 8 is more stable and efficient.

[0030] See the attached specification Figure 3 As shown, the material distribution partition structure 10 includes three partitions 1003 distributed in parallel for forming two collection channels. A hanger 1001 is fixedly arranged on the second rack 801, and three suspension rods 1002 for respectively fixing and hoisting the three partitions 1003 are arranged on the hanger 1001. These two channels are used to sort and collect the boxes that have undergone visual inspection and preliminary transmission according to the forward and reverse directions, realizing the classification processing of boxes in different states, and ensuring that the subsequent processes can perform targeted operations on boxes in different directions.

[0031] See the attached specification Figure 6 、 Figure 8 and Figure 9As shown in the figure, the positive and negative adjustment mechanism 11 includes a rotating support block 1102, which is rotatably arranged between two partition plates 1003. A first servo motor 1101 for driving the rotation of the rotating support block 1102 is fixedly arranged on the partition plate 1003. A sliding cavity 1107 is formed in the rotating support block 1102, and a guiding sliding groove 1103 for communicating the sliding cavity 1107 with the outside is formed on the outside of the rotating support block 1102. Two clamping sliders 1109 are slidably arranged at both ends in the sliding cavity 1107. A second electric telescopic rod 1108 for adjusting the distance between them is arranged between the two clamping sliders 1109. Each clamping slider 1109 passes through the guiding sliding groove 1103 and is fixedly provided with a sliding seat 1104. A clamping plate 1106 is fixedly arranged on the sliding seat 1104, which is in direct contact with the box body. By adjusting its position and being driven when the rotating support block 1102 rotates, the clamping and flipping operations of the box body are realized. It is the direct execution component for realizing the positive and negative adjustment of the box body. A number of anti-slip cushion strips 1105 are arranged on the side where the two clamping plates 1106 are close to each other, increasing the friction between the clamping plate 1106 and the box body, preventing the box body from sliding during the clamping and flipping of the box body, and ensuring that the box body can be stably clamped and the direction can be adjusted. Through the coordinated work of each component, the positive and negative adjustment mechanism 11 realizes the precise adjustment of the reverse box body. First, the second electric telescopic rod 1108 adjusts the distance between the clamping plates 1106 according to the size of the box body to realize the stable clamping of the box body; then, the first servo motor 1101 drives the rotation of the rotating support block 1102, driving the clamping plate 1106 and the box body to flip together, and adjusting the reverse box body to the positive direction. This mechanism cooperates with the material distribution partition structure 10 to ensure that the equipment can effectively process boxes in different directions, improving the integrity and accuracy of the whole equipment for box body processing and meeting the requirements for box body direction adjustment in actual production.

[0032] See the attached drawings of the specification Figure 5 As shown in the figure, the stopping structure 12 includes a rotating shaft 1202 rotatably arranged between two partition plates 1003. One end of the rotating shaft 1202 is driven to rotate by a second servo motor 1201 fixedly arranged on the partition plate 1003. A baffle 1203 is arranged on the rotating shaft 1202. When the baffle 1203 rotates to a position perpendicular to the box body transmission direction, it can block the forward box body from continuing to be transmitted, making the box body stay at this position to realize the collection function; when the baffle 1203 rotates to a position parallel to the box body transmission direction or deviates by a certain angle, the box body can pass through smoothly to realize the release function. Working principle: In use, the cartridge 13 containing the liquid medicine is first transported by the first conveyor 2. The first drive motor 203 of the first conveyor 2 drives the first conveyor belt 202 to operate. The swing drive motor 601 of the swing drive mechanism 6 drives the swing wheel 603 to rotate through a speed reducer, and the first conveyor 2 swings around the swing support shaft 406 through the eccentric connecting rod 606 to adjust the transmission angle; the second swing support wheel 502 of the support swing wheel structure 5 provides auxiliary support.

[0033] During the transportation of the cartridge by the first conveyor 2, the vision detector 3 performs positive and negative vision detection on the cartridge 13. After the detection, the first electric telescopic rod 708 of the lateral conveyor 7 adjusts the distance between the two push connecting rods 709 to adapt to the size of the cartridge 13, and the third drive motor 704 drives the belt pulley 702 to make the lateral conveyor belt 703 operate, guiding the cartridge to be output.

[0034] The three partitions 1003 of the material distribution partition structure 10 form two collection channels. When the cartridge is transported to the second conveyor 8 under the swing of the first conveyor 2, it is sorted into different channels according to the vision detection results. During this process, the air cylinder 902 of the linear drive assembly 9 pushes the linear slider 903 to slide in the linear chute 906, so that the second conveyor 8 moves through the moving wheel 905 in the wheel groove 904, adjusting the distance from the first conveyor 2 to achieve closeness during material receiving and distance during the swing of the first conveyor 2.

[0035] For the reverse cartridges entering the channel provided with the positive and negative adjustment mechanism 11, after accumulating a certain number, the second electric telescopic rod 1108 adjusts the distance between the clamping sliders 1109, so that the anti-slip strip 1105 of the clamping plate 1106 clamps the cartridge. The first servo motor 1101 drives the rotating support block 1102 to rotate and flip 180°. The second electric telescopic rod 1108 adjusts the distance between the clamping sliders 1109 to become larger, so that the anti-slip strip 1105 of the clamping plate 1106 releases the cartridge and falls on the second conveyor 8 for continuous transportation. During this process, the second servo motor 1201 drives the rotating shaft 1202 and the baffle 1203 to rotate, realizing the blocking of the positive cartridges 13. After the positive and negative adjustment mechanism 11 flips and moves the reverse cartridges 13, the baffle 1203 releases the blocking of the positive cartridges 13, thereby realizing the cross-transportation of the cartridges 13 on the two collection channels and avoiding side-by-side overlap during transportation.

Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention.
