Description

Testing institutions and conveying equipment Technical Field

[0001] This application relates to the field of battery manufacturing technology, and more specifically, to a testing mechanism and a conveying device. Background Technology

[0002] In the battery manufacturing process, cell tracking and management are crucial for ensuring product quality and production efficiency. After undergoing multiple processes on the production line, a QR code containing unique identification information is usually printed on the side of the cell. This QR code stores information such as the cell's batch number, production date, and specifications. To verify the consistency between the actual cell information and the production flow records, and to avoid process errors caused by information mismatches, the cell code is usually identified during the production process.

[0003] Currently, standalone barcode scanning workstations are commonly used in the market for identifying battery cell codes. These workstations are typically designed with a rotary station and a barcode scanner. A mechanical structure rotates the battery cell or the holder supporting it to ensure the scanner can capture the QR code information on the side of the cell. However, this design usually requires moving the battery cells from the conveyor line to the rotary station for rotation and identification. This process—including cell handling, rotation, positioning, and scanning—all takes time, disrupting the conveyor cycle and impacting the overall efficiency of the production line.

[0034] Technologies and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such technologies and equipment should be considered part of the specification.

[0035] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0036] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0037] This application provides a detection mechanism 100 for detecting materials on a conveyor turntable 200 to identify information about the materials on the turntable 200, thereby facilitating conveying control. The materials include, but are not limited to, battery cells and electrode sheets.

[0038] As shown in Figures 1 and 2, the testing organization 100 provided in this application includes:

[0039] Support 1, which is movably connected to the mounting platform and is capable of moving relative to the mounting platform in a first direction;

[0040] The adjustment part includes an adjustment component 2 and a mounting component 3. The adjustment component 2 is movably connected to the support part 1 and is capable of moving relative to the support part 1 along a second direction, and the second direction has a first angle with the first direction. The mounting component 3 is connected to the adjustment component 2.

[0041] At least two detection units 4 are movably connected to the mounting assembly 3, and each detection unit 4 is movable relative to the mounting assembly 3, such that at least one of the detection angle and detection distance between the corresponding detection unit 4 and the material can change.

[0042] As shown in Figures 1 and 2, the support part 1 serves as the structural foundation of the entire detection mechanism 100. Its main function is to stably and reliably connect to the mounting platform and support the adjustment part and other structures. The support part 1 can be movably connected to the mounting platform via guide rails, sliders, screw slots, etc., allowing the detection mechanism to move relative to the mounting platform in a first direction, such as the front-back direction shown in Figure 2, i.e., the Y direction. This allows adjustment of the distance between the detection mechanism 100 and the material on the conveyor turntable 200, enabling the detection mechanism 100 to adapt to materials of different sizes and shapes, as well as detection requirements at different positions.

[0043] As shown in Figure 1, the adjusting component 2 can be movably connected to the support part 1, allowing the adjusting component 2 to move relative to the support part 1 along a second direction, such as the vertical direction (Z direction) shown in Figure 1. A first angle is set between the second direction and the first direction, for example, the first angle shown in Figure 1 can be 90 degrees. This ensures that the direction of movement of the adjusting component 2 is not consistent with the direction of movement of the support part 1, thereby allowing the position of the detection mechanism 100 to be adjusted from different directions to adapt to different detection needs and improve the detection reliability and convenience of the detection mechanism 100.

[0044] The first included angle can be an acute angle, an obtuse angle, or a right angle, such that the movement directions of the adjusting component 2 and the support part 1 are not the same.

[0045] Alternatively, the adjustment component 2 can be movably connected to the support part 1 through structures such as guide rail sliders, screw waist-shaped holes, and lead screw nuts, so as to facilitate the movement of the adjustment component 2.

[0046] As shown in Figure 1, the mounting component 3 is connected to the adjustment component 2. The mounting component 3 is used to install and support two, three, four or more detection units 4 so as to realize the detection function of the detection mechanism 100.

[0047] The structure of the mounting component 3 can be designed according to the specific form and layout requirements of the detection unit 4. For example, if multiple detection units 4 need to be arranged linearly, the mounting component 3 can be designed as a long strip mounting plate; if multiple detection units 4 need to be arranged in a two-dimensional array, the mounting component 3 can be designed as a planar plate or a grid structure.

[0048] As shown in Figure 1, at least two detection units 4 are movably connected to the mounting assembly 3. Each detection unit 4 can move relative to the mounting assembly 3 to achieve changes in the detection angle and / or detection distance. The movement of the detection unit 4 can be achieved through rotational movement, translational movement, or a combination of these movements.

[0049] The detection unit 4 includes, but is not limited to, barcode scanners, barcode readers, and various sensors. Different detection units 4 can be selected to adapt to different detection scenarios and material types, giving the detection mechanism 100 high versatility and scalability.

[0050] Specifically, in one embodiment, to achieve a change in the detection angle, each detection unit 4 can be mounted on a rotating shaft, which is movably connected to the mounting assembly 3 via a bearing or similar structure. By driving the rotating shaft to rotate via a motor or similar means, the detection unit 4 can be rotated, thereby changing the detection angle between the corresponding detection unit 4 and the material, facilitating detection and identification.

[0051] In another embodiment, to achieve the variation of the detection distance, each detection unit 4 can be mounted on a translation mechanism, which may include a slide rail, a slider, and a cylinder. By pushing the slider on the slide rail with the cylinder, the detection unit 4 can be driven to produce translational motion, thereby changing the detection distance between the corresponding detection unit 4 and the material, facilitating detection and identification.

[0052] Regarding the aforementioned variation in the detection distance between the detection unit 4 and the material, the movement direction of the detection unit 4 can be set to be consistent with one of the two directions, the second direction and the first direction. This allows for precise control of the detection distance between the detection unit 4 and the material through fine-tuning, helping to reduce detection errors caused by improper positioning or angular deviations, and improving the accuracy and consistency of the detection results. Alternatively, the movement direction of the detection unit 4 can be set to be completely different from both the second and first directions, allowing for adjustment of the position of the detection mechanism 100 from different directions to adapt to different detection needs.

[0053] In another embodiment, in order to simultaneously achieve changes in detection angle and detection distance, the detection unit 4 can be designed to perform compound motion, that is, the detection unit can simultaneously achieve both rotation and translation. For example, the detection unit 4 can be mounted on a rotating shaft, and the rotating shaft can be mounted on a translation mechanism. By simultaneously controlling the movement of the rotating shaft and the translation mechanism, the compound motion of the detection unit 4 can be achieved.

[0054] In this way, at least two detection units 4 can be used to quickly detect materials from multiple angles during the conveying process of the conveying turntable 200, which reduces the working time occupied by the detection process and does not interfere with the conveying process of the conveying turntable 200, thereby ensuring production efficiency and reliability.

[0055] Furthermore, each inspection unit 4 can move independently, enabling the inspection mechanism 100 to perform multiple inspection tasks simultaneously or separately. For example, one inspection unit 4 can be used for dimensional measurement, while another inspection unit 4 can be used for defect detection, thereby greatly improving inspection efficiency and comprehensiveness.

[0056] In use, the detection mechanism 100 is first connected to the mounting platform via the support 1. Then, based on the specific location and shape of the material, the position and orientation of the mounting assembly 3 and the detection unit 4 are adjusted via the adjustment assembly 2. Next, the detection angle and / or detection distance of the detection unit 4 are adjusted as needed to obtain the optimal detection effect. Finally, multiple detection units 4 are activated to perform detection operations, enabling at least one detection unit 4 to perform detection and identification.

[0057] Optionally, the mounting assembly 3 includes at least two connecting plates and a rotating plate 33, with one end of each connecting plate connected to the rotating plate 33 and the other end of each connecting plate movably connected to one of the detection units 4.

[0058] As shown in Figure 1, the number of connecting plates is the same as the number of detection units 4. The connecting plates are used to connect the detection units 4 to the rotating plate 33, so that the adjustment assembly 2 can drive the detection units 4 to move through the rotating plate 33.

[0059] Depending on actual needs, the connecting plate can be designed as a single rectangular plate, a single triangular plate, a single circular plate, or a single plate of other shapes, or a combination of multiple such plates, so that the movement trajectory of the detection unit 4 can be adjusted from different angles to adapt to different detection requirements.

[0060] The rotating plate 33 can be rotatably connected to the output shaft of the adjusting assembly 2, so that it can rotate and drive the multiple detection units 4 thereon to rotate, so as to facilitate detection. Connecting the multiple detection units 4 to the outer periphery of the rotating plate 33 can also prevent the movement of the detection units 4 from interfering with the rotating plate 33.

[0061] Optionally, each of the connecting plates includes a first connecting plate 31 and a second connecting plate 32, the first connecting plate 31 and the second connecting plate 32 are movably connected and have a second included angle, the detection unit 4 is movably connected to the first connecting plate 31, and the second connecting plate 32 is fixed to the rotating plate 33.

[0062] As shown in Figure 1, the connecting plate may include a first connecting plate 31 and a second connecting plate 32 connected at an angle, which can facilitate assembly and adjust the movement trajectory of the detection unit 4 from different angles to adapt to different detection needs.

[0063] The first connecting plate 31 and the second connecting plate 32 are movably connected. For example, one of the first connecting plate 31 and the second connecting plate 32 has a guide rail, and the other has a slider; or, one of the first connecting plate 31 and the second connecting plate 32 has a slotted hole, and the other has a screw. Both of these configurations enable the movable connection between the first connecting plate 31 and the second connecting plate 32, allowing relative movement between them. This allows the movement trajectory of the detection unit 4 to be adjusted from different angles, facilitating adaptation to different detection requirements.

[0064] Optionally, the first connecting plate 31 has a first waist-shaped hole 311, and the detection part 4 can slide along the first waist-shaped hole 311. The second connecting plate 32 has a second waist-shaped hole 321, and the first connecting plate 31 can slide along the second waist-shaped hole 321. There is a third included angle between the long axis direction of the first waist-shaped hole 311 and the long axis direction of the second waist-shaped hole 321.

[0065] As shown in Figure 1, the first connecting plate 31 has a first waist-shaped hole 311, and the detection part 4 has a first screw. The first screw is movably connected to the first waist-shaped hole 311 and can slide within the first waist-shaped hole 311, thereby causing the detection part 4 to move as well.

[0066] Similarly, the second connecting plate 32 has a second oblong hole 321, and the first connecting plate 31 has a second screw. The second screw is movably connected to the second oblong hole 321 and can slide within the second oblong hole 321, thereby causing the first connecting plate 31 to move as well.

[0067] Thus, the detection unit 4 can move relative to the first connecting plate 31, and the first connecting plate 31 can move relative to the second connecting plate 32. Specifically, a third angle is formed between the major axis of the first oblong hole 311 and the major axis of the second oblong hole 321, causing the direction of movement of the detection unit 4 relative to the first connecting plate 31 to differ from the direction of movement of the first connecting plate 31 itself. This allows the movement trajectory of the detection unit 4 to be adjusted from two directions, facilitating adaptation to different detection requirements.

[0068] The third included angle can be an acute angle, an obtuse angle, or a right angle, such that the direction of movement of the detection unit 4 relative to the first connecting plate 31 is not the same as the direction of movement of the first connecting plate 31 itself.

[0069] For example, the movement direction of the first connecting plate 31 relative to the second connecting plate 32 can be set to the front-back direction, i.e., the Y direction, as shown in Figure 2, and the movement direction of the detection unit 4 relative to the first connecting plate 31 can be set to the left-right direction, i.e., the X direction, as shown in Figure 2.

[0070] Optionally, the first waist-shaped hole 311 is an arc-shaped hole;

[0071] And / or, the second waist-shaped hole 321 is a rectangular hole, and the long axis of the rectangular hole is horizontal.

[0072] In one embodiment, the first waist-shaped hole 311 can be set as an arc-shaped hole, that is, the first screw can drive the detection part 4 to slide in the arc-shaped hole, thereby adjusting the detection angle between the detection part 4 and the material.

[0073] In another embodiment, the second waist-shaped hole 321 can be set as a rectangular hole with the long axis of the rectangular hole in the horizontal direction, such as the front-back direction shown in Figure 2, i.e., the Y direction, so that the second screw can drive the first connecting plate 31 to move horizontally, thereby adjusting the detection distance between the detection unit 4 and the material.

[0074] In another embodiment, the first waist-shaped hole 311 can be set as an arc-shaped hole and the second waist-shaped hole 321 as a rectangular hole. The long axis of the rectangular hole is horizontal, such as the front-back direction shown in Figure 2, which is the Y direction. This allows the first screw to drive the detection part 4 to slide in the arc-shaped hole, and the second screw to drive the first connecting plate 31 to move horizontally, thereby adjusting the detection angle and detection distance between the detection part 4 and the material.

[0075] Optionally, the adjusting assembly 2 includes an adjusting rod 21 and a fixing ring 22. The rotating plate 33 has a first through hole, and the support part 1 has a second through hole. The second through hole is opposite to the first through hole. The adjusting rod 21 passes through the second through hole and is connected to the inner wall of the first through hole. The adjusting rod 21 can move along the second direction. The fixing ring 22 is sleeved on the adjusting rod 21 and can form a locking fixation.

[0076] As shown in Figure 1, the end of the adjusting rod 21 may be provided with an external thread, and the inner wall of the first through hole may be provided with an internal thread. The threaded engagement of the two enables a detachable connection between the adjusting rod 21 and the rotating plate 33. After adjusting the adjusting rod 21 to the predetermined position, the retaining ring 22 fitted on the adjusting rod 21 is locked to prevent the adjusting rod 21 from shaking or shifting, thus ensuring the reliable assembly of the mounting assembly 3.

[0077] Specifically, a groove can be provided on the adjusting rod 21, and a protrusion adapted to the groove can be provided on the fixing ring 22. After the adjusting rod 21 is adjusted to the predetermined position, the protrusion is inserted into the groove, which can also achieve the fixing and locking of the adjusting rod 21. Other commonly used fixing methods can also be applied, which will not be described in detail here.

[0078] Optionally, the adjustment assembly 2 further includes a third connecting plate 23 and a fixing member 24. The support portion 1 is also provided with a third through hole. The fixing member 24 passes through the third connecting plate 23 and can be connected to the inner wall of the third through hole. The end of the adjustment rod 21 away from the first through hole is connected to the third connecting plate 23, and the third connecting plate 23 can restrict the movement trajectory of the adjustment rod 21.

[0079] As shown in Figure 1, the axial direction of the fixing member 24 is parallel to the second direction, which ensures that the adjusting rod 21 moves only along the second direction and does not rotate, thereby guaranteeing the reliability of the adjustment. The fixing member 24 includes, but is not limited to, fixing screws and fixing bolts.

[0080] Optionally, the number of the detection units 4 is three, four, or five, and the plurality of the detection units 4 are uniformly connected to the mounting assembly 3 in the circumferential direction.

[0081] Specifically, by adjusting the number of detection units 4, the size and type of materials conveyed on the conveyor turntable 200 can be adapted, facilitating rapid material detection. Furthermore, by evenly connecting multiple detection units 4 circumferentially to the mounting assembly 3, the detection area of ​​the detection mechanism 100 can be increased, further enabling rapid material detection.

[0082] Optionally, the support 1 includes a first support member 11 and a second support member 12 connected together. The first support member 11 is movably connected to the mounting platform, and the second support member 12 is used to set the adjustment component 2.

[0083] As shown in Figure 1, the support part 1 may include two connected support members, a first support member 11 and a second support member 12. The first support member 11 can be movably connected to the mounting platform through a guide rail slider, screw waist-shaped hole, etc., so that the detection mechanism can move relative to the mounting platform along a first direction, such as the front-back direction shown in Figure 2, i.e., the Y direction. This allows the distance between the detection mechanism 100 and the material on the conveying turntable 200 to be adjusted, so that the detection mechanism 100 can adapt to materials of different sizes and shapes, as well as detection requirements at different positions.

[0084] The second support member 12 is fixedly connected to the first support member 11. The second support member 12 is used to set the adjustment component 2. The split design of the support part 1 facilitates the assembly of the detection mechanism 100.

[0085] As shown in Figure 3, this application also provides a conveying device, including a conveying turntable 200 and the detection mechanism 100. During the process of the conveying turntable 200 rotating to convey materials, at least one of the detection units 4 can face the materials and perform detection.

[0086] As shown in Figure 3, the feed turntable 300 is used to transport materials to the conveyor turntable 200 for inspection by the inspection mechanism 100. The inspection mechanism 100 is located close to the conveyor turntable 200 so that at least one inspection unit 4 of the inspection mechanism 100 can perform rapid inspection of the materials.

[0087] When non-conforming materials are detected, the conveyor turntable 200 transfers them to the rejection turntable 500, whereby the rejection cylinder 600 further transfers them to the collection box 700, thus achieving material classification and recycling. When conforming materials are detected, the conveyor turntable 200 transfers them to the discharge turntable 400 for use in subsequent processes. This allows for material detection during normal conveying without stopping the material transport process, avoiding any impact on material transport and ensuring production efficiency and reliability.

[0088] The above embodiments mainly describe the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be elaborated here.

[0089] While specific embodiments of this application have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of this application. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of this application. The scope of this application is defined by the appended claims.
