Description

Technical Field

[0001] The present invention relates to the field of intelligence, digitization and automation technology, and specifically to a digital assembly production system for a level, a cylindrical vial detection device, a digital assembly production method for a level including a cylindrical vial, and a level detection device. Background Art

[0002] The level is a precision measuring tool widely used in construction, engineering and daily life. With the development of modern industry, the requirements for the accuracy and quality of the level are constantly increasing, and traditional production and testing methods can no longer meet market demand.

[0003] At present, the production process of the level ruler mainly has the following problems:

[0004] Low production efficiency: Traditional assembly lines often use fixed workstations, lack flexibility, and are difficult to adapt to the production needs of different batches and models.

[0005] Unstable quality control: Manual testing is easily affected by subjective factors, resulting in inconsistent test results and making it difficult to ensure the stability of product quality.

[0006] Difficult traceability: The lack of a complete digital management system makes it difficult to achieve full traceability, which is not conducive to problem location and continuous improvement.

[0007] Inefficient inventory management: Traditional inventory management methods make it difficult to accurately predict demand, which can easily lead to inventory backlogs or shortages.

[0008] The detection process is complicated: Existing level bubble detection equipment can usually only detect a single or a small number of samples, which is difficult to meet the needs of mass production. For example, the authorization announcement number CN 220568062 U level bubble position detection equipment adopts a sealed shell design and is equipped with at least two groups of photoelectric devices: the first group is a light-emitting or receiving device, and the second group is not less than four, which is a receiving or light-emitting device. Although the two groups of devices have improved the detection accuracy through the precision photoelectric system, they are still limited to the detection of a single or a small number of samples, and cannot meet the rapid detection needs of large-scale production, resulting in a complicated and inefficient detection process.

[0009] Lack of flexibility: Existing production systems are difficult to respond quickly to changes in market demand, product switching time is long, and resource utilization is low. For example, the fully automatic level bubble comprehensive parameter detector disclosed in the authorization announcement number CN 219841914 U, although it realizes automated detection based on pure visual technology and improves speed and accuracy, its design still focuses on the optimization of a single function and fails to fully solve the problem of insufficient flexibility of the production system.

[0010] Although some companies have begun to introduce automated equipment and information systems, they have not yet achieved digital and intelligent integration of the entire production process. Summary of the invention

[0011] In view of this, the present invention provides a digital assembly production system for a level ruler, a cylindrical level bubble detection device, a digital assembly production method for a level ruler including a cylindrical level bubble, and a level ruler detection device, aiming to improve production efficiency and ensure product quality through intelligent and automated technical means.

DETAILED DESCRIPTION

[0111] The following will combine all the attached Figure 1 -Attached Fig.17; The preferred embodiments of the present invention are described in detail. It should be noted that the following description is only a preferred embodiment of the present invention, rather than a limitation of the present invention. Those skilled in the art should understand that various modifications and variations can be made to the present invention without departing from the spirit and scope of the present invention. The scope of protection of the present invention shall be subject to the attached claims.

[0112] Embodiment 1:

[0113] Reference Figure 1 , a digital assembly production system for level rulers. The core of this system lies in its comprehensive digital capabilities, which runs through the entire assembly and inspection process of the level ruler. Through advanced digital technologies such as the Internet of Things (IoT), big data, cloud computing and artificial intelligence (AI), the production process has been made intelligent, precise and efficient. The following will elaborate on how to embody the digital core in the automated assembly line.

[0114] The system consists of the following main parts:

[0115] 1. Intelligent warehousing system, refer to Figure 2 The system uses a three-layer coding to uniquely identify each component for easy classification, storage and retrieval. The coding structure is C(i,j,k) = f(i) * 10000 + g(j) * 100 + h(k).

[0116] Where i represents the type of component (1: shell, 2: end cap, 3: label, 4: level bubble, 5: scale); j represents the specification, different sizes or models; k represents the production batch; f, g, h are mapping functions that map the original value to a specific range. For example, f(i) may be {1:1, 2:2, 3:3, 4:4, 5:5}, g(j) may be the specification number, and h(k) may be the last two digits of the batch number. Representation: C(i,j,k) = f(i) * 10000 + g(j) * 100 + h(k) defines a method to combine three different dimensions of information (component type, specification, production batch) into a single coded value C(i,j,k). This encoding method is very useful in data management and tracking because it allows a complex entity or object to be uniquely represented by a simple value.

[0117] Where: f(i) * 10000: f(i) is a mapping function that maps component type i to a specific value (as mentioned earlier, f(1) may be 1, f(2) may be 2, and so on). The purpose of multiplying this value by 10000 is to assign a high-order position to component type i in the encoding value C(i,j,k), thereby ensuring that different types of components are clearly distinguished in the encoding.

[0118] g(j) * 100: g(j) is another mapping function that maps specification j to a numeric value. The purpose of multiplying by 100 is to assign a middle position to specification j in the encoding so that it will not be confused with part type or production batch. At the same time, since the number of specifications is usually much smaller than the number of part types, multiplying by 100 ensures that the specification code has enough space to distinguish different specifications.

[0119] h(k): h(k) is the third mapping function, which maps the production batch k to a numerical value (which may be the last two digits of the batch number or other simplified representation). In this formula, h(k) is directly used as the low-order part of the code because it does not need to occupy the high-order position like the part type or specification.

[0120] Adding these three parts together, we get a single coded value C(i,j,k) that contains part type, specification, and production batch information. This coded value can be used in a variety of scenarios such as database records, barcodes, RFID tags, etc. to track and manage parts throughout the production, warehousing, and logistics process.

[0121] For example, if f(1) = 1 (indicating a shell), g(23) = 23 (indicating a certain specification), and h(123) = 34 (indicating that the last two digits of the production batch are 34), then C(1,23,123) = 1 * 10000 + 23 * 100 + 34 = 10234. This code value 10234 can be used to uniquely identify this specific shell component, including its type, specification, and production batch information.

[0122] 2. Intelligent access algorithm: This algorithm takes into account the distance between components in physical space and the similarity between components to optimize the access path, reduce misaccess and improve overall efficiency. Algorithm formula: D(p,q) = √[(x_p - x_q)² +(y_p - y_q)² + (z_p - z_q)²] + w * |C(p) ​​- C(q)|

[0123] Where (x, y, z) represents the three-dimensional coordinates of the storage location; C(p) and C(q) are the codes of the two components; w is a weight factor used to balance the importance of physical distance and component similarity;

[0124] Algorithm steps: S1 calculates the weighted distance D(p,q) between the part p to be picked up and all other parts q; S2 selects k nearest neighbors (k is usually 3-5); S3 plans the optimal material picking path based on the positions of these k neighbors.

[0125] This method not only takes into account the physical distance, but also the similarity of components, which can effectively reduce mispick and improve efficiency.

[0126] 3. Inventory forecasting model, which combines traditional time series analysis (ARIMA) and deep learning (LSTM) methods. Model formula: I(t+1) = α * ARIMA(I(t)) + (1-α) * LSTM(I(t), O(t))

[0127] Among them, I(t) represents the inventory at time t, O(t) represents the order quantity at time t, and α is the weight coefficient used to balance the contribution of the two models.

[0128] Algorithm steps:

[0129] S1 uses historical inventory data to train an ARIMA model

[0130] S2 uses historical inventory and order data to train an LSTM model

[0131] S3 uses ARIMA and LSTM to predict the new time point t+1.

[0132] S4 combines the prediction results of the two models according to the weight α

[0133] This hybrid method not only takes into account the cyclicality and trend of inventory (ARIMA is good at), but also captures complex nonlinear patterns (LSTM is good at).

[0134] 4. Flexible assembly line design

[0135] 4.1 Dynamic workstation allocation; see Figure 4 Dynamic workstation allocation cost matrix, optimization objective: minimize total cost: min Σ Σ c_ij * x_ij; constraints: Σ x_ij = 1 (each task can only be assigned to one workstation); Σ x_ij = 1 (each workstation can only perform one task); x_ij ∈ {0,1} (decision variable is 0 or 1);

[0136] Where: c_ij represents the cost of workstation i to perform task j (which can be time, resource consumption, etc.); x_ij is a decision variable, 1 means allocation, 0 means no allocation.

[0137] Algorithm steps: Construct the cost matrix C = [c_ij], normalize each row and column; assign workstations based on the matching results.

[0138] 4.2 Assembly cycle optimization; Optimization objective: F = min(T_max) + λ * Σ|T_i - T_avg|.

[0139] Where: T_max is the maximum workstation time; T_i is the workstation time; T_avg is the average workstation time; λ is the balance factor;

[0140] Algorithm steps (based on genetic algorithm): S1. Initialize a set of random assembly sequences; S2. Calculate the fitness F of each sequence; S3. Select individuals with high fitness for crossover and mutation; S4. Generate a new generation of population; S5. Repeat steps 2-4 until the termination condition is reached. This method can optimize the assembly sequence, minimize the total assembly time, and balance the load of each station.

[0141] 5. Assembly process

[0142] 5.1 Receiving Orders

[0143] The MES system receives order information from ERP; generates unique digital assembly instructions, including product model, quantity, delivery date and other information; and triggers subsequent intelligent batching and production scheduling.

[0144] 5.2 Intelligent batching

[0145] The optimal material retrieval path is calculated using an intelligent storage and retrieval algorithm. The AGV follows the optimized path to retrieve materials from designated storage locations. Each component is scanned by RFID and compared with digital assembly instructions to ensure correctness. If there is any mismatch, the system will immediately sound an alarm and suspend batching.

[0146] 5.3 Level Bubble Pre-check

[0147] The level bubble enters a dedicated inspection station; the collected image is processed using an image preprocessing algorithm;

[0148] Apply bubble position accuracy assessment algorithm; calculate comprehensive quality score; upload test data to MES system in real time and associate it with the unique ID of each level bubble; refer to Figure 3 Quality assessment criteria for level bubbles in.

[0149] 5.4 Flexible Assembly

[0150] Use a dynamic workstation allocation algorithm to assign tasks based on current orders and workstation status; apply an assembly rhythm optimization algorithm to determine the optimal assembly sequence; the digital twin system monitors the status of each workstation in real time, including equipment parameters, operation time, etc.; robots or operators perform assembly according to the optimized sequence; the system automatically updates the progress after each assembly step is completed.

[0151] 5.5 Online quality control

[0152] After each critical assembly step, a machine vision system is used for inspection; statistical process control (SPC) methods are applied to calculate the mean and standard deviation of key parameters in real time; if an abnormality is detected, the system immediately alarms and suspends the production line; quality engineers can remotely diagnose problems through the digital twin system.

[0153] 5.6 Finished product testing

[0154] The assembled level enters the finished product inspection station; it is fully inspected using a method similar to the pre-inspection of the bubble level; additional checks include scale accuracy, shell integrity, etc.; a digital quality report is generated, containing all inspection data and the final score; the report is automatically linked to the product's unique ID to achieve full traceability.

[0155] 5.7 Intelligent Packaging and Warehousing

[0156] The system automatically selects appropriate packaging materials and methods based on the product model and test results; robots or automatic packaging machines complete the packaging process; print and paste smart labels containing product information and traceability codes; AGV carts deliver packaged products to designated storage locations; update inventory information, and trigger inventory forecasting models to optimize future procurement plans.

[0157] This highly digitalized and intelligent assembly process enables high efficiency, high quality and full traceability of the level production process. Each step is supported by a corresponding algorithm to ensure the accuracy and reliability of the entire process.

[0161] 1. Frame 10: As the main supporting structure of the whole device, it has a platform 11. For the convenience of description and understanding, we set up the corresponding coordinate system XYZ in the length, width and height directions of the frame.

[0162] 2. Inspection fixture 20: Located above the platform 11, it has an upper flat surface 21. The upper flat surface 21 is provided with a plurality of rows of vials 22 parallel to the X axis and a plurality of columns parallel to the Y axis, forming a regular matrix layout. Each vial accommodating hole 22 is provided with a lifting block 221 that can move up and down (it can be understood that the movable limit between the lifting block 221 and the vial accommodating hole 22 can be completed by any structure that can be realized). This design allows the position of the cylindrical vial 100 to be accurately controlled. For each column of vial accommodating holes 22, air passages 222 that are interconnected are provided at the bottom thereof, and these air passages are guided to the fixture surface for easy connection with the external air pressure system. By controlling the air pressure, the lifting block 221 can be moved up and down, thereby accurately adjusting the position of the cylindrical vial 100. In the entire inspection device, at least one such inspection fixture is arranged, but a more preferred solution is to arrange multiple inspection fixtures in parallel. This multi-jig design concept allows that when the cylindrical vials 100 in one jig are being inspected, the cylindrical vials 100 in adjacent jigs can be loaded or unloaded simultaneously, thereby significantly improving the efficiency of the entire inspection process and realizing parallel operation of the inspection, loading and unloading processes.

[0163] 3. Linear transport assembly 30: The orientation reference coordinate system of this assembly design can move along the Y-axis direction, and its number and position correspond to the layout setting of the detection fixture 20. The linear transport assembly 30 includes a movable part and a fixed part. Some parts of the movable part are connected to the detection fixture 20 to achieve precise movement of the detection fixture; the fixed part is fixedly connected to the platform 11 of the frame to ensure the stability of the entire transport system. The fixed part includes a track 31, a mounting beam 32 for positioning the track 31 and fixedly connected to the frame 10, a power seat 33 and a screw seat 34. The movable part includes a screw 35, a screw nut 36 and a slider 37. These components work together to achieve precise positioning and smooth movement of the detection fixture. It is worth noting that the linear transport assembly 30 adopts a design commonly used in the industry, and some of the parts that are not described in detail are well known to those skilled in the art, so they will not be repeated.

[0164] 4. Visual inspection mechanism 40: Located above the inspection fixture 20, the reference coordinate system can move along the X-axis and Z-axis directions. The mechanism includes a light source assembly, a CCD camera 41, a fixed seat 42 for mounting the light source assembly and the CCD camera, and a transmission assembly 43 for pushing the fixed seat 42 to move. The light source assembly provides the necessary lighting for the inspection process to ensure that the CCD camera 41 can capture a clear image of the cylindrical level bubble 100. The CCD camera 41 is responsible for obtaining high-precision images of the cylindrical level bubble 100, providing basic data for subsequent analysis and quality control. The fixed seat 42 not only provides a stable installation platform for the light source assembly and the CCD camera 41, but also realizes the precise movement of the visual inspection mechanism in the X-axis and Z-axis directions through cooperation with the transmission assembly 43. Similarly, the transmission assembly 43 adopts a mature design in the industry, and its specific details are not described in detail here.

[0165] V. Material shifting and spacing mechanism 50: It is a key component to ensure the accurate positioning of the cylindrical vial 100, including a backing plate 51, a spacing actuator 52 and a driving mechanism 53. The backing plate 51 is a long strip member, the entire large surface of which is set on the upper flat surface 21, has a backing surface 511 and is parallel to the Y axis, covers the entire upper flat surface 21 in the Y axis direction, and is in close and slidable contact with the upper plane 21 at two edges in the Y axis direction. The spacing actuator 52 is also a long strip member, with a plate surface 521 and a working surface 522, and its length is close to that of the backing plate 51. The plate surface is attached to the backing plate 51 and is hinged to the backing plate 51 at one end, and the other end can be opened and closed relative to the backing plate 51. The working surface 522 is provided with a plurality of arc concave surfaces 523, which are spaced in the same manner as the vial accommodating hole 22, and the curvature of each arc concave surface 523 matches the cylindrical arc surface of the cylindrical vial 100. The driving mechanism 53 is arranged between the backrest plate 51 and the spacing actuator 52, for example, a cylinder is used to drive the opening and closing. In order to adapt to the arc movement during pushing, the connection between the cylinder body or the telescopic free end and the backrest plate 51 or the spacing actuator 52 is rotatable in the horizontal plane. It is worth noting that when the spacing actuator 52 is closed and the backrest plate 51 is in the appropriate position, each arc concave surface 523 is coaxial with the level bubble accommodating hole 22 below it. At this time, the space between each arc concave surface 523 and the backrest surface 511 is just enough to slightly clamp the cylindrical level bubble 100 or leave a very small gap. This space is used to position the cylindrical level bubble 100.

[0166] 6. The butt joint 60 is arranged on the side of the backing plate 51 away from the hinge, and its overall shape is to extend a section along the length direction.

[0167] 7. A feeding mechanism 70 is arranged on one side of the docking head 60. It can be translated within the range of the X-axis direction of the entire detection fixture 20. The device for realizing the translation preferably adopts a component that is morphologically the same as the aforementioned linear transport component 30 to carry its translation. A connecting portion 71 that can be temporarily engaged with or separated from the docking head 60 is provided in the feeding mechanism 70. The implementation method is that the connecting portion 71 and the docking head 60 are consistent in height in the Z-axis, and the translation of the feeding mechanism 70 is used to adjust the alignment of the connecting portion 71 and the docking head 60 in the X-axis direction. The movement of the docking head 60 in the conveying direction is actively engaged with or separated from the connecting portion 71. The preferred connection method is sleeve-fitting. After engagement, the docking head 60 and the integrated material-shifting and spacing mechanism 50 are driven by the feeding mechanism 70 to move in the X-axis direction, thereby realizing that the material-shifting and spacing mechanism 50 conveys and spaces the cylindrical vials 100 for the vial accommodating holes 22 of each column on the detection fixture 20.

[0168] The whole working process is as follows: First, the feeding mechanism 70 is connected to the docking head 60, so that the material-dividing and spacing mechanism 50 is driven by the feeding mechanism 70 in the X-axis direction. In a row of vial accommodating holes 22 ready for loading, the lifting block 221 is pushed by air pressure to be flush with the upper edge of the accommodating hole, so that the vial can pass smoothly on the bottom surface. The material-dividing and spacing mechanism 50 stops at the appropriate position of the row ready for loading (usually starting from the first row on one side), and the spacing actuator 52 remains in an open state. Through the external feeding mechanism 01, a large number of cylindrical vials 100 are arranged and pushed along the backing plate 51 of the material-dividing and spacing mechanism 50. By using induction control, it is ensured that the backing surface 511 of the backing plate 51 is closely filled with cylindrical vials 100. Then, the spacing actuator 52 is shear-closed, starting from the hinge, and slowly approaches the backing plate 51. In this process, each cylindrical vial 100 in front along the conveying direction will push the adjacent cylindrical vial 100 to move backwards when entering the arc concave surface 523 due to the resistance of the shear-like tangent movement of the arc concave surface 523, so that the closely adjacent cylindrical vials 100 are separated in turn until each cylindrical vial 100 is completely fitted with the corresponding arc concave surface 523. The distance actuator 52 to be separated is completely closed, and all cylindrical vials 100 are accurately positioned, that is, all cylindrical vials 100 are located on the corresponding lifting blocks 221. The lifting blocks 221 are then controlled to descend by air pressure, so that the cylindrical vials 100 are completely placed and enter the state to be inspected. Subsequently, the feeding mechanism 70 is translated to move the material separation mechanism 50 to the next row of vial accommodating holes 22, and the above-mentioned actions are repeated until all vial accommodating holes 22 of the inspection fixture 20 are loaded. This design not only ensures the precise positioning of the cylindrical level bubble 100, but also greatly improves the loading efficiency, laying the foundation for subsequent testing work. The whole process is highly automated, reducing human intervention and improving production efficiency and consistency.

[0169] During inspection, the visual inspection mechanism 40 moves to an appropriate position. Since the height of each column of cylindrical vials 100 is individually controllable, the lifting block 221 can be driven in different ways according to different inspection items to control the height of the cylindrical vials 100 in the relative columns, so as to make the inspection process more flexible and accurate. For example, when inspecting the position of the vials, all vials can be adjusted to the same height to ensure that the visual system can capture a consistent image; when inspecting the appearance or size of the vials, the height can be adjusted column by column so that each column of vials can enter the best observation position in turn;

[0170] The CCD camera 41 captures the image of the level bubble, while the light source assembly provides the necessary lighting to ensure image clarity. The fixed seat 42 and the transmission assembly 43 work together to achieve precise positioning of the visual inspection mechanism in the X-axis and Z-axis directions to accommodate levels of different heights and positions. The image data is transmitted to the relevant image processing and analysis system in real time to evaluate the quality of the level bubble. This process can be carried out simultaneously or sequentially on multiple inspection jigs as needed, further improving the inspection efficiency.

[0171] The detection system can evaluate multiple parameters, such as the size, shape, position accuracy of the bubble, transparency of the glass tube, clarity of the scale, etc. By adjusting the height of the lifting block 221, the performance of the level bubble at different tilt angles can also be tested to comprehensively evaluate its performance. After the test is completed, unqualified levels can be marked or directly removed through the corresponding mechanism, while qualified levels can enter the next process. Figure 3 The following is one of the calculation methods listed for evaluating the quality of the vial.

[0172] In some embodiments, an adjustable structure that is raised by power control may be added to the arc concave surface 523 of the distance actuator 52. This structure usually uses a micro airbag or a flexible raised element driven by air pressure, which can be extended and retracted as needed. When the distance action is required, these raised structures can be expanded by controlling the air pressure, thereby increasing the degree of resistance to the cylindrical level bubble 100.

[0173] In some embodiments, reference Figure 6 For the backing plate 51, a limiting top plate 512 is provided on the upper edge of the backing surface 511 to limit the excessive movement space of the cylindrical vial 100 in the X-axis and Z-axis directions. The limiting top plate 512 also has a baffle 513 extending downward, the inner side of the baffle 513 is parallel to the backing surface 511, and the spacing is slightly larger than the cylinder diameter of the cylindrical vial 100. In this way, the cylindrical vial 100 can be controlled to be in a neat row when being transported and arranged, which is beneficial for spacing positioning.

[0174] In some embodiments, based on the foregoing embodiments, Figure 7-Figure 8 , a belt conveyor line 80 is provided around the backing surface 511 of the backing plate 51. In this way, when the cylindrical vial 100 is transported, the cylindrical vial 100 entering the backing surface 511 can be actively pushed forward by the belt conveyor line 80, which can reduce the pushing force of the feeding mechanism 70 during transportation. The belt conveyor line 80 includes a conventional driving wheel (not shown), a driven wheel 81, a belt 82 (in Figure 7 The driving wheel is shown in a disassembled form for easy observation) and a driving motor 83, the power output shaft of the driving motor 83 is connected to the driving wheel in power.

[0175] In some embodiments, a guide member 72 is provided in the feeding mechanism 70 for guiding the cylindrical vial 100 into the backing plate 51 .

[0176] In some embodiments, in the feeding mechanism 70, the conveying body adopts a combination of rollers and conveyor belts as shown in the accompanying drawings. Figure 7 , Fig.11 , Fig.12 At this time, a transition plate 73 is provided on the side of the backing plate 51 facing the feeding mechanism 70, which can be connected with the roller arc position of the feeding mechanism 70. It is worth noting that if the conveyed body is not a roller arc shape, but a plate shape, the transition plate 73 is not needed.

[0177] In some embodiments, in the design of the feeding mechanism 70, the connecting portion 71 is a key component, which is not only responsible for connecting the butt joint 60 to the feeding mechanism body, but also needs to ensure the stability and reliability of this connection during dynamic operation. To this end, the present design innovatively introduces a locking mechanism to achieve an additional locking function for the butt joint 60.

[0178] Working principle: The locking mechanism is designed to provide an additional locking force after the connection part 71 is combined with the docking head 60 by mechanical or pneumatic means to prevent accidental separation caused by vibration, impact or other external factors. Figure 7 In the example shown, a cylinder-driven connecting rod clamping mechanism is used as an implementation method of the locking mechanism. The mechanism drives the connecting rod through the telescopic action of the cylinder, so that one end of the connecting rod presses the docking joint 60, thereby achieving a locking effect.

[0179] Diversified implementation: It is worth noting that the cylinder-driven connecting rod clamping mechanism is only one of the many implementation methods of the locking mechanism. In practical applications, other types of locking mechanisms can be flexibly selected or designed according to specific needs and environmental conditions, such as spring-loaded locking mechanisms, electromagnetic locking devices, and precision locking systems based on hydraulic or servo motor drives. These alternatives can meet the requirements of locking strength, response speed, accuracy and cost to varying degrees.

[0180] In some embodiments, reference Figure 8 , Fig. 9 , the detection fixture 20 is set as a separate structure, aiming to improve the flexibility and efficiency of the detection. It includes: an upper movable part 24 with an upper flat surface 21 (as mentioned above, the upper flat surface 21 has a plurality of rows of vial accommodating holes 22, and an air channel 222 at the bottom), and a lower fixed part 25 connected to the linear carrier assembly 30 for supporting the upper movable part 24 and providing its movement restriction. The upper movable part 24 and the lower fixed part 25 are in arc contact and cooperation in the X-axis direction, and the movement of the upper movable part 24 relative to the lower fixed part 25 is controlled by a power mechanism, so as to obtain the horizontal and inclination of the upper flat surface 21 in the X-axis direction. The transition from the horizontal to the inclined position can be used to detect the fluidity of the liquid in the vial, which is helpful to evaluate the sensitivity performance of the vial. On the other hand, when the inspection process is completed, or when the level bubble needs to be removed from the inspection fixture, the upper flat surface 21 is adjusted to a certain inclined position, and then through the ejection action of the lifting block 221, the cylindrical level bubble 100 can be smoothly removed from its accommodating hole 22 and slide along the inclined surface of the upper flat surface 21 to the predetermined collection area, thereby realizing a fast and efficient unloading operation.

[0181] In some embodiments, the transmission assembly of the aforementioned power mechanism is configured as an arc-shaped rack 26 fixed to the lower part of the upper movable part 24, a gear 27 meshing with the arc-shaped rack 26, and a power source, such as a motor or a cylinder, that drives the gear 27 to rotate.

[0182] In some embodiments, in order to ensure that the discharge of the cylindrical vial 100 can be correctly guided, a retractable belt assembly 28 with a main body fixed thereto is respectively provided on both sides of the upper flat surface 21 at the discharge end. The belt head of the retractable belt assembly 28 is fixed on the material-dividing and spacing mechanism 50. Thus, referring to FIG. 8 , when the material-dividing and spacing mechanism 50 is away from the side of the cylindrical vial 100 ready for the outlet, the pulled-out retractable belt can play the role of blocking the cylindrical vial 100 on the side.

[0216] Embodiment 3:

[0217] This embodiment aims to provide an innovative detection device for detecting finished level rulers with metal adsorption properties. The device makes full use of the split design of the detection fixture 20 - the upper movable part 24 and the lower fixed part 25, and their special functions, including the tilting ability and the ejection characteristics of the lifting block 221, to achieve efficient and accurate detection of the level ruler.

[0218] Device design overview:

[0219] Material selection of the upper flat surface 21: In order to satisfy the metal adsorption property of the level ruler, the upper flat surface 21 is specially made of a material that can be attracted by magnetism.

[0220] Application of the split structure: By controlling the inclination of the upper movable part 24 relative to the lower fixed part 25, different working conditions can be simulated, thereby evaluating the performance of the level at different angles.

[0221] Innovative design of lifting block 221: In this embodiment, lifting block 221 not only has the basic ejection function, but is also specially designed to be higher than the plane of upper flat surface 21. This design allows lifting blocks 221 to act as "backers" or spacers when activated, providing the required spacing arrangement for level ruler detection. This spacing arrangement helps to ensure the relative position of the level rulers during the detection process, thereby improving the accuracy and reliability of the detection.

[0222] Tilt adjustment and visual inspection: By adjusting the tilt of the upper flat surface 21, different tilt states of the level in actual use can be further simulated. At the same time, such tilt adjustment allows visual inspection to more easily capture any minor deviations or defects of the level, thereby improving inspection efficiency and accuracy.
