It integrates multiple links such as sample collection, transmission, testing, sealing and storage, and realizes the automation and intelligent management of the whole process. The assembly line adopts advanced automation technology to realize the full process automation processing of samples from collection to sealing, reduce manual intervention, and improve test efficiency and accuracy. The anonymous test method is adopted to ensure the fairness and objectivity of the test. During the test process, the identification and tracking of samples are managed by the automation system to avoid interference from human factors.

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] In order to enable those skilled in the art to better understand the solution of the present application, the following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0022] Please refer to Figures 1 to 8, an unmanned automatic sample sealing production line for anonymous testing of multiple devices, comprising: a mechanical gripper 1, an electric box 4 is arranged on one side of the mechanical gripper 1, a label stripping machine 5 is arranged on the electric box 4, a conveying component is arranged on one side of the mechanical gripper 1, and a placement plate 72 is arranged above the conveying component; the conveying component is responsible for conveying the device or sample from the input end to the designated position, and conveying the sealed device or sample to the output end, so as to realize the continuous conveying of the object. The mechanical gripper 1 is one of the core components of the production line, responsible for grasping and moving objects. It is mainly used to grasp the peeled label from the label stripping machine 5, and to grasp the device or sample from the conveying component to the placement plate 72 for sample sealing operation, realizing the automation of the whole process from grasping, conveying, label stripping to sample sealing, and greatly improving the work efficiency. Through the precise cooperation of the mechanical gripper 1 and the label stripping machine 5, the accuracy and consistency of the sample sealing operation are ensured. It reduces manual participation, reduces labor costs and safety risks, and can expand and customize the production line according to actual needs to meet the sample sealing requirements of different devices or samples.

[0023] Please refer to Figures 1 to 8 , an unmanned automatic sample sealing production line for anonymous testing of multiple devices, further comprising a positioning mechanism, the positioning mechanism being arranged on a conveying assembly, the positioning mechanism comprising a rotating plate 87 symmetrically arranged on one side of the conveying assembly, the rotating plate 87 being arranged in a C shape, a fixed rod 810 being fixedly arranged on the top of the rotating plate 87, a clamping block 99 being arranged on the fixed rod 810, and the positioning mechanism being used for quickly positioning the placement plate 72 to the operating area of ​​the mechanical gripper 1; in the initial state, the rotating plate 87 is in an open state, allowing the placement plate 72 to pass smoothly from the conveying assembly, and when the placement plate 72 needs to be positioned, the conveying assembly transports the placement plate 72 to the designated position. At this time, the rotating plate 87 begins to rotate under the action of the driving mechanism, gradually driving the clamping block 99 close to the placement plate 72, and when the rotating plate 87 is fully rotated into place, the clamping block 99 closely cooperates with the corresponding structure on the placement plate 72, and firmly positions the placement plate 72 in the operating area of ​​the mechanical gripper 1. Through the cooperation of the rotating plate 1 87 and the clamping block 2 99, the positioning mechanism can quickly position the placement plate 72 to the operating area of ​​the mechanical gripper 1, thereby improving the efficiency of the assembly line. The design of the positioning mechanism ensures the accuracy and stability of the placement plate 72 during the positioning process, thereby avoiding operational errors caused by inaccurate positioning.

[0024] Please refer to Figures 1 to 8, an unmanned automatic sample sealing production line for anonymous testing of multiple devices, further comprising a fixing mechanism, the fixing mechanism being arranged on a positioning mechanism and a conveying assembly, the fixing mechanism comprising a rotating plate 2 95 symmetrically arranged on one side of the conveying assembly, the rotating plate 2 95 being arranged in an L shape, a fixing rod 2 98 being fixedly arranged on the top of the rotating plate 2 95, a clamping block 2 99 being fixedly arranged on the fixing rod 2 98, the fixing mechanism and the positioning mechanism being linked to each other to cause the position of the placement plate 72 to be relatively fixed. The fixing mechanism and the positioning mechanism are linked to each other to jointly realize the rapid positioning and fixing of the placement plate 72. When the conveying assembly conveys the placement plate 72 to the designated position, the positioning mechanism first starts to work, and the placement plate 72 is initially positioned by rotating the rotating plate 1 87. At the same time, the fixing mechanism works synchronously, the rotating plate 2 95 rotates under the action of the driving mechanism, so that the clamping block 2 99 and the placement plate 72 are mutually abutted and fixed, and the placement plate 72 is firmly fixed in the operating area of ​​the mechanical gripper 1.

[0025] Among them, a base 2 is provided at the bottom of the mechanical gripper 1, and the base 2 provided at the bottom of the mechanical gripper 1 provides a stable support for it, ensuring that the mechanical gripper 1 can remain stable and accurate when performing operations such as grasping and moving. An electric cabinet 3 is provided at the rear side of the mechanical gripper 1, and the electric cabinet 3 is used to control the mechanical gripper 1 to execute the set program. The electric cabinet 3 contains necessary electrical components and control systems, such as PLC (programmable logic controller), relays, power supplies, etc. Guardrails 6 are provided on both sides of the mechanical gripper 1 to protect the operator from being injured when the mechanical gripper 1 moves. At the same time, the guardrail 6 can also prevent debris from entering the working area of ​​the mechanical gripper 1 to ensure the normal operation of the assembly line. The conveying assembly includes a support frame 7 fixedly provided on one side of the mechanical gripper 1. The support frame 7 is usually made of steel structure or aluminum alloy structure and has sufficient strength and rigidity. Its height and width should be designed according to the size of the placement plate 72 and the overall layout of the assembly line. A number of conveying rollers 71 are rotatably provided on the support frame 7, and the conveying rollers 71 are driven by an external drive motor to rotate and drive the placement plate 72 to move. The rotation speed and direction of the conveying roller 71 can be adjusted by the control system to adapt to the placement plates 72 of different sizes and weights. The conveying roller 71 is usually made of wear-resistant and corrosion-resistant materials, such as stainless steel or rubber. Its surface usually has an anti-skid texture to increase the friction between it and the placement plate 72 to prevent the placement plate 72 from sliding during the conveying process. The external drive motor provides power to the conveying roller 71 so that it can rotate smoothly.

[0026] It should be noted that a card slot 73 is symmetrically provided at the top edge of the placement plate 72, and the card slot 73 and the card block 811 are adapted to each other. A card slot 2 74 is symmetrically provided at the top edge of the placement plate 72, and the card slot 2 74 and the card block 99 are adapted to each other. The shapes, sizes and positions of the card slot 1 73 and the card slot 2 74 are determined according to the design of the card block 811 and the card block 99 to ensure that they can fit closely. Card slots and card blocks with good adaptability can reduce friction and wear, and improve the operating efficiency and accuracy of the assembly line. Through the cooperation of the card slot and the card block, the placement plate 72 can be firmly fixed at a certain position of the assembly line to avoid sliding or offset during the process of conveying, grabbing and sealing. This fixing method not only improves the stability of the assembly line, but also reduces the operational safety risks.

[0027] Please refer to Figures 2 to 6 as well as Figure 8 Further, the positioning mechanism also includes a fixed plate 8 fixedly arranged at the bottom of the support frame 7, a three-axis cylinder 81 is fixedly installed on the fixed plate 8, an output shaft 82 is movably installed on the three-axis cylinder 81, a top plate 83 is fixedly connected to the top of the output shaft 82, a clamping rod 84 is symmetrically fixedly arranged on the side wall of the top plate 83, and the clamping rod 84 is located between one group of adjacent conveying rollers. A fixed block 85 is also fixedly arranged symmetrically on the top plate 83, a connecting shaft 86 is fixedly arranged between the opposite surfaces of the fixed block 85, and the connecting shaft 86 is rotatably connected to the rotating plate 1 87. A groove 88 is opened through the rotating plate 1 87, and the groove 88 is bent. A fixed shaft 1 89 is penetrated through the inner wall of the groove 88, and both ends of the fixed shaft 1 89 are fixedly arranged on the support frame 7.

[0028] When the top plate 83 is lifted up by the output shaft 82 of the three-axis cylinder 81, the clamping rod 84 is driven to move upward synchronously. At the same time, the rotating plate 87 rotates along the fixed axis 89 through the groove 88. At this time, the clamping block 811 is separated from the clamping groove 73, and there is enough space on the conveying assembly to allow the adjacent placement plate 72 to be conveyed to the working area of ​​the mechanical gripper 1. Under the restriction of the clamping rod 84, the placement plate 72 for the unsealed sample device is restricted from moving. When the placement plate 72 for the sealed sample completely leaves the working area of ​​the mechanical gripper 1, the output shaft 82 of the three-axis cylinder 81 pulls the top plate 83 to move to one side of the bottom of the support frame 7. At this time, the placement plate 72 for the unsealed sample device is gradually released from the restriction and is conveyed to the working area of ​​the mechanical gripper 1 through the conveying assembly until it is completely located in the working area. The fixed rod 810 on the rotating plate 87 drives the clamping block 811 to be clamped into the clamping groove 73, so as to realize the rapid positioning of the placement plate 72 in the effective working area.

[0029] Please refer to Figures 2 to 5 as well as Figure 8Furthermore, the fixing mechanism also includes a mounting plate 9 fixedly arranged on the support frame 7, and a limiting column 91 is symmetrically fixedly arranged on the mounting plate 9. A spring 92 is sleeved on the outer surface of the limiting column 91, and one end of the spring 92 is fixedly connected to the mounting plate 9. The fixing mechanism also includes a mounting rod 93 symmetrically and fixedly arranged on the support frame 7, and a fixed shaft 2 94 is fixedly arranged on the opposite surface of the mounting rod 93, and the fixed shaft 2 94 is rotatably connected to the rotating plate 2 95. A connecting rod 96 is fixedly arranged at one end of the rotating plate 2 95 away from the fixing rod 2 98, and a spherical block 97 is fixedly arranged at one end of the connecting rod 96 close to the top plate 83.

[0030] When the top plate 83 is lifted up by the output shaft 82 of the three-axis cylinder 81, the block 2 99 of the fixing mechanism is driven to synchronously break away from the restriction of the slot 2 74. At this time, the placement plate 72 on which the unsealed sample equipment is placed is transported to the working area of ​​the mechanical gripper 1 through the conveying assembly; when the three-axis cylinder 81 pulls the top plate 83 away from the conveying roller 71, the rotating plate 2 95 is gradually reset under the action of the spring 92, and the block 2 99 above the rotating plate 2 95 is inserted into the slot 2 74, and the placement plate 72 is fixed to the conveying assembly. Through the coordinated work of the three-axis cylinder 81, the top plate 83, the block 2 99 of the fixing mechanism, the slot 2 74, the rotating plate 2 95 and the spring 92, the unmanned automatic sample sealing production line realizes the precise control and fixation of the placement plate 72. This design not only improves the degree of automation and production efficiency, but also enhances the stability of the placement plate 72 during the transportation process, simplifies the operating procedures, and reduces maintenance costs, which together promote the optimization and upgrading of the assembly line, improve the overall production efficiency, and avoid the need for the visual recognition camera to continuously shoot and record the position, and then make corresponding adjustments to the working position, affecting the overall operation of the system and causing the overall sealing timeline to be further extended.

[0031] Through all the above embodiments, the working principle of the present invention is: In the initial state, the fixing mechanism and the positioning mechanism are in a non-limiting state, and the equipment to be sealed is neatly placed on the placement plate 72 according to the position, and the conveying roller 71 of the conveying assembly rolls to convey the placement plate 72 and the equipment thereon to the working area and then stops conveying; The conveying assembly conveys the placement plate 72 to the designated position. At this time, the rotating plate 1 87 starts to rotate under the action of the driving mechanism. The rotating plate 1 87 rotates along the fixed axis 1 89 through the groove 88, and gradually drives the clamping block 2 99 close to the placement plate 72. When the rotating plate 1 87 is fully rotated into place, the clamping block 2 99 cooperates closely with the corresponding structure on the placement plate 72 to firmly position the placement plate 72 in the operating area of ​​the mechanical gripper 1. Through the cooperation of the rotating plate 1 87 and the clamping block 2 99, the positioning mechanism can quickly position the placement plate 72 in the operating area of ​​the mechanical gripper 1, thereby improving the efficiency of the assembly line. The design of the positioning mechanism ensures the accuracy and stability of the placement plate 72 during the positioning process, and avoids operational errors caused by inaccurate positioning; When the top plate 83 is lifted up by the output shaft 82 of the three-axis cylinder 81, the block 2 99 of the fixing mechanism is driven to synchronously break away from the restriction of the slot 2 74. At this time, the placement plate 72 for the unsealed sample device is transported to the working area of ​​the mechanical gripper 1 through the conveying assembly. At the same time, under the restriction of the clamping rod 84, the placement plate 72 for the unsealed sample device is restricted from moving. When the placement plate 72 for the sealed sample completely leaves the working area of ​​the mechanical gripper 1, the output shaft 82 of the three-axis cylinder 81 pulls the top plate 83 to move to the bottom side of the support frame 7. At this time, the placement plate 72 for the unsealed sample device is gradually released from the restriction and is transported to the working area of ​​the mechanical gripper 1 through the conveying assembly until it is completely located in the working area. When the three-axis cylinder 81 pulls the top plate 83 away from the conveying roller 71, the rotating plate 2 95 gradually resets under the action of the spring 92, and the block 2 99 above the rotating plate 2 95 is inserted into the slot 2 74, and the placement plate 72 is fixed on the conveying assembly. Through the coordinated work of the three-axis cylinder 81, the top plate 83, the block 2 99 of the fixing mechanism, the slot 2 74, the rotating plate 2 95 and the spring 92, the unmanned automatic sample sealing production line realizes the precise control and fixation of the placement plate 72. This design not only improves the degree of automation and production efficiency, but also enhances the stability of the placement plate 72 during the conveying process, simplifies the operation process, and reduces the maintenance cost, which jointly promotes the optimization and upgrading of the production line, improves the overall production efficiency, and avoids the problem that the visual recognition camera needs to continuously shoot and record the position, and then adjust the working position accordingly, which affects the overall operation of the system and further extends the timeline of the overall sample sealing.
