Description

Technical Field

[0001] This invention relates to the field of laser detection technology, and more specifically, to a detection device and its detection method. Background Technology

[0002] In the process of mechanical manufacturing and production, the requirements for product appearance and precision are extremely stringent, often necessitating the inspection of the product's shape. Traditional inspection methods include physical measurements and image capture via cameras. Physical measurements are difficult, time-consuming, and labor-intensive, while camera-based measurements typically require multiple cameras for different inspection angles, resulting in a complex and costly structure that is also difficult to operate. Therefore, existing measurement methods for product shape inspection, especially when multi-angle and multi-area measurements are required, are not only difficult to operate but may also lead to excessively long inspection times and high overall costs. Summary of the Invention

[0003] In order to at least partially solve the problems existing in the prior art, according to one aspect of the present invention, a detection device is provided, the technical solution of which is as follows.

[0004] The detection device includes a carrier component and a detection component. The carrier component is used to carry the material to be tested, which has at least a first region, a second region, and a third region. The second region and the third region are located on both sides of the first region. The detection component is disposed above the carrier component and is movable relative to the carrier component so that the material to be tested has at least a first position, a second position, and a third position relative to the detection component. The detection component has a first detection module, a second detection module, and a third detection module. The first detection module is used to acquire an image of the first region when the material to be tested is in the first position relative to the detection component. The second detection module is used to acquire an image of the second region when the material to be tested is in the second position relative to the detection component. The third detection module is used to acquire an image of the third region when the material to be tested is in the third position relative to the detection component.

[0005] The detection device provided by this invention comprises detection components of a first detection module, a second detection module, and a third detection module. A support component can move relative to the detection components. When the support component is in a first position relative to the detection components, the first detection module can acquire an image of a first region on the material to be tested. When the support component is in a second position relative to the detection components, the second detection module can acquire an image of a second region on the material to be tested. When the support component is in a third position relative to the detection components, the third detection module can acquire an image of a third region on the material to be tested. The second and third regions are located on opposite sides of the first region. Therefore, the detection components can perform multi-region detection on the material to be tested, and multi-dimensional detection of the material to be tested can be achieved through the relative movement of the support component and the detection components. Using such a detection device for shape detection of the material to be tested is simpler and more convenient, the time required to complete the detection is shorter, and the overall cost is lower.

[0006] For example, at least one of the second and third detection modules is configured as a bidirectional detection assembly. The bidirectional detection assembly includes a first lateral detection element and a second lateral detection element. The second and third regions each have a surface to be detected. The surface to be detected in the second region and the surface to be detected in the third region are disposed opposite each other on both sides of the first region. The surface to be detected has an inner surface facing the first region and an outer surface away from the first region. The first lateral detection element is used to acquire an image of the inner surface, and the second lateral detection element is used to acquire an image of the outer surface. When in use, such a detection device can perform multi-angle detection on complex structures within different regions of the material to be tested, even if those regions have different complex structures. This meets the multi-size detection needs of more types of materials to be tested, and its overall applicability is wider. Moreover, because such a detection device can perform multi-angle detection on partial regions of the material to be tested, the detection effect is better.

[0007] For example, the bidirectional detection assembly also includes a base, with the first lateral detection element and the second lateral detection element respectively adjustablely connected to the base. Such a detection device, while enabling multi-angle detection of specific areas of the material to be tested, can further improve the detection effect by adjusting the relative position and angle between the first lateral detection element and the base, and by adjusting the relative position and angle between the second lateral detection element and the base, allowing for better detection of specific areas of the material to be tested from better angles. This can meet the specific needs of multi-size detection of different materials to be tested.

[0008] For example, the bidirectional detection assembly further includes a connector, an adjusting member, and a rotating member. The connector is movably connected to the base along a first direction, the adjusting member is movably connected to the connector along a second direction, and the rotating member is rotatable about the first direction and movably connected to the adjusting member along a third direction. At least one of the first and second lateral detection members is connected to the rotating member and rotatable about the first direction, with the first, second, and third directions forming certain angles with each other. Such a detection device, by adjusting the position and angle of the first and / or second lateral detection members, can achieve multi-dimensional detection of materials of any form, thereby meeting the needs of multi-dimensional detection of more materials. This not only broadens the applicability of the overall device but also improves the detection effect. Furthermore, by adjusting the connection of the first and / or second lateral detection members to the base in this manner, the overall structure is simpler and easier to manufacture.

[0009] For example, the first direction, the second direction, and the third direction are perpendicular to each other. When the first direction, the second direction, and the third direction are perpendicular to each other, they can form a spatial rectangular coordinate system. This makes adjusting the position of the first lateral detection component and / or the second lateral detection component simpler and easier to operate. Moreover, when the first direction, the second direction, and the third direction are perpendicular to each other, the structure of the connecting component, the adjusting component, and the rotating component can be simpler, and the connection form between them can also be simpler, thus making the overall structure simpler and easier to implement.

[0010] For example, the detection device includes a base frame, and a base connected to the base frame and movable relative to the base frame in a second direction. Such a detection device, by adjusting the position of the base relative to the base frame in the second direction, enables the bidirectional detection component to detect the material to be tested at a better position and angle. Furthermore, the bidirectional detection component can perform multi-dimensional detection on various forms of the material to be tested, thus making the detection device as a whole applicable to multi-dimensional detection of more forms of the material to be tested, broadening its overall applicability, and achieving better detection results.

[0011] For example, the first detection module has a light-emitting surface configured to emit detection light rays in a vertical direction. Because the first detection module is configured to emit detection light rays vertically, its structure can be simpler, and the overall structure of the detection device can also be simpler. Furthermore, such a first detection module is easier to operate. When such a detection device detects the material to be tested, the overall operation is simpler, the time required to complete the detection is shorter, the overall structure is simpler, and thus the overall cost is lower.

[0012] For example, the detection device includes a conveying assembly for conveying a carrier assembly along a predetermined detection path, with a first position, a second position, and a third position sequentially located on the predetermined detection path. The carrier assembly can move with the conveying assembly, allowing the detection assembly to remain stationary. This means the detection assembly can be fixedly installed, simplifying installation, simplifying the overall structure, and reducing overall cost. Furthermore, this relative movement between the carrier assembly and the detection assembly via the movement of the carrier assembly simplifies the detection process.

[0013] For example, the testing device includes a base frame and a fixed mounting platform. A testing component is mounted on the base frame, which is movably connected to the mounting platform along a predetermined testing path. A support component is fixedly mounted on the mounting platform. Because the support component is fixed, the material to be tested remains stationary during testing. Thus, testing of the material can be completed simply by moving the testing component, better protecting the material from falling or being damaged during movement.

[0014] For example, the carrier component has a rotating structure for rotating the material to be tested by a specified angle to form a rotated material. The material to be tested also has a fourth region and a fifth region, which are located on opposite sides of the first region. The second, third, fourth, and fifth regions are located around the periphery of the first region. A second detection module is used to acquire an image of the fourth region when the rotated material is in a second position relative to the detection component, and a third detection module is used to acquire an image of the fifth region when the rotated material is in a third position relative to the detection component. Such a detection device can detect more regions of the material to be tested, thereby enabling multi-size detection of various forms of materials to be tested, and thus has a wider overall applicability.

[0015] According to another aspect of the present invention, a detection method is provided for any of the detection devices described above, the detection method comprising the steps of:

[0016] The detection component is moved relative to the carrier component until the material to be tested is in a first position relative to the detection component, and an image of the first area is acquired through the first detection module;

[0017] The detection component is moved relative to the support component until the material to be tested is in a second position relative to the detection component, and an image of the second region is acquired through the second detection module;

[0018] The detection component is moved relative to the carrier component until the material to be tested is in a third position relative to the detection component, and the image of the third region is obtained through the third detection module.

[0019] When this detection method is applied to a detection device, it is only necessary for the carrier component to carry the material to be tested between the first, second, and third positions. For example, the carrier component can carry the material to be tested from the first position to the second position and then from the second position to the third position. The detection component can then complete the multi-size detection of the material to be tested. The overall detection process can be shorter and the operation is simpler.

[0020] For example, the material to be tested also has a fourth region and a fifth region, which are located on opposite sides of the first region, and the second, third, fourth, and fifth regions are located around the first region. The detection method includes the following steps:

[0021] The material to be tested in the carrier component is rotated by a specified angle to form rotated material. The detection component is then moved relative to the carrier component until the rotated material is in a second position relative to the detection component. An image of the fourth region is then obtained through the second detection module.

[0022] And / or, move the detection component relative to the carrier component again until the material is in a third position relative to the detection component after rotation, and obtain an image of the fifth region through the third detection module.

[0023] This detection method eliminates the need for multiple detection positions relative to the detection components when testing the material under test, making the testing process simpler.

[0024] A series of simplified concepts are introduced in the description of the invention, which will be further explained in detail in the detailed description section. This description is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

Detailed Implementation

[0036] In the following description, numerous details are provided to enable a thorough understanding of the invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the invention, and that the invention can be practiced without one or more of these details. Furthermore, to avoid obscuring the invention, some technical features well-known in the art have not been described in detail.

[0037] According to one aspect of the present invention, a detection apparatus is provided that can detect a material to be tested. See also... Figure 1 and Figure 2The detection device 1 may include a support assembly (not shown) and a detection assembly 20. The support assembly can be used to support the test material having at least a first region, a second region, and a third region, with the second and third regions located on opposite sides of the first region. The support assembly may include a support platform or other structure of any form that facilitates the placement of the test material. The first, second, and third regions may each be three parts of the test material, with the second and third regions located on opposite sides of the first region, meaning that the three regions on the test material can be arranged in the order of second region, first region, and third region. It is understood that, through simple design, the test material can be divided into first, second, and third regions, and then the first, second, and third regions can be detected separately to complete the detection of the test material. The first, second, and third regions are simply three regions defined on the material under test. This division is solely for ease of differentiation and for zonal testing of the material. The material does not require any special structure to distinguish these regions. Similarly, the second and third regions located on either side of the first region are not necessarily symmetrical about the first region, nor is the material limited to being entirely composed of these three regions. In some embodiments, the material may also have a fourth and fifth region. For example, the division of the first, second, and third regions can be made by considering the location of special structural dimensions on the material. For instance, when the material is a battery casing, both the inner and outer sides of the casing's sidewalls need to be tested. In this case, the first region can be divided to include the bottom wall of the battery casing, and the second and third regions can be divided to each include one side wall of the battery casing. This allows for targeted testing of the battery casing's sidewalls when testing the second and third regions separately, meeting the testing requirements for complex dimensions. For the battery casing, there may be two additional sidewalls that the second and third regions cannot cover. In this case, the material to be tested can be further divided into a fourth and fifth region. The second, fourth, third, and fifth regions can sequentially surround the first region. Each of these four regions can also include one sidewall of the battery casing. Thus, when testing the second, third, fourth, and fifth regions, all four sidewalls of the battery casing can be targeted for testing, thereby meeting the full-size testing requirements of the battery casing. It is worth noting that the first, second, and third regions are used only for illustrative purposes and are not intended to limit the scope of the test.

[0038] The detection component 20 can be disposed above the support component. The detection component 20 is movable relative to the support component so that the material to be tested can have at least a first position, a second position, and a third position relative to the detection component 20. The detection component 20 can have a first detection module 21, a second detection module 22, and a third detection module 23. The first detection module 21 can be used to acquire an image of a first area when the material to be tested is in the first position relative to the detection component 20. The second detection module 22 can be used to acquire an image of a second area when the material to be tested is in the second position relative to the detection component 20. The third detection module 23 can be used to acquire an image of a third area when the material to be tested is in the third position relative to the detection component 20.

[0039] The detection component 20 is movable relative to the support component. This can be because both the detection component 20 and the support component are movable, or one of them is fixed while the other is movable, allowing relative movement. For example, the detection component 20 can be fixed, while the support component is movable relative to it, allowing the support component to carry the material to be tested and move relative to the detection component 20, enabling the material to be tested to move between first, second, and third positions relative to the detection component 20. Similarly, the support component can be fixed, while the detection component 20 is movable relative to it, also allowing the material to be tested to move between first, second, and third positions relative to the detection component 20. Figure 1 and Figure 2 In the illustrated embodiment, the detection component 20 can be mounted on the base frame 30, which can be fixedly mounted in a suitable installation position. The supporting component can be movable relative to the base frame 30. For example, a guide rail can be provided at the installation position of the base frame 30, and the supporting component can be slidably mounted on the guide rail. The supporting component can move along the guide rail, thereby enabling the supporting component to move relative to the detection component 20. In an embodiment not shown, the detection component 20 can also be mounted on the base frame 30, which can be slidably mounted on the guide rail. A supporting component can be fixedly mounted above the guide rail. By sliding the detection component 20 along the guide rail with the base frame 30, the relative movement between the detection component 20 and the supporting component can be achieved. Here, the first position, second position, and third position of the material to be tested relative to the detection component 20 only reflect the relative positional relationship between the material to be tested and the detection component 20. The first position, second position, and third position are all relative to the detection component 20 and do not specifically refer to three positions in space. Since the carrier component and the detection component 20 can move relative to each other, when the detection component 20 is considered to be stationary, the carrier component has a predetermined movement path relative to the detection component 20. The first position, second position and third position of the material to be tested relative to the detection component 20 can respectively correspond to the three positions of the carrier component on the predetermined movement path.

[0040] The first position of the material to be tested relative to the detection component 20 can be associated with the detection range of the first detection module 21, the second position can be associated with the detection range of the second detection module 22, and the third position can be associated with the detection range of the third detection module 23. When the material to be tested is located in the first position relative to the detection component 20, it facilitates the first detection module 21 to detect the first area and acquire an image. When the material to be tested is located in the second position relative to the detection component 20, it facilitates the second detection module 22 to detect the second area and acquire an image. When the material to be tested is located in the third position relative to the detection component 20, it facilitates the third detection module 23 to detect the third area and acquire an image. Therefore, it can be understood that the first position, the second position, and the third position do not necessarily refer to three specific positions, but can be understood as three positional ranges. If the location of the material to be tested is convenient for the first detection module 21 to detect the first area and acquire an image, then the material to be tested can be considered to be in a first position relative to the detection component 20. If the location of the material to be tested is convenient for the second detection module 22 to detect the second area and acquire an image, then the material to be tested can be considered to be in a second position relative to the detection component 20. If the location of the material to be tested is convenient for the third detection module 23 to detect the third area and acquire an image, then the material to be tested can be considered to be in a third position relative to the detection component 20. Based on this, the detection component 20 does not require the material to be tested to be stationary when detecting the material to be tested. For example, when the first detection module 21 in the detection component 20 detects the first area, the material to be tested can move within the position range of the first position; when the second detection module 22 in the detection component 20 detects the second area, the material to be tested can move within the position range of the second position; and when the third detection module 23 in the detection component 20 detects the third area, the material to be tested can move within the position range of the third position. Thus, during the relative movement of the carrier component and the detection component 20, the material to be tested moves between the first position, the second position and the third position relative to the detection component 20. The detection component 20 can detect the material to be tested synchronously with the relative movement. In this way, the detection component 20 can complete the detection of the material to be tested while the material to be tested is moving relative to the detection component 20, and the detection efficiency can be higher.

[0041] The detection device 1 provided by this invention comprises a detection component 20 consisting of a first detection module 21, a second detection module 22, and a third detection module 23. A supporting component can move relative to the detection component 20. When the supporting component is in a first position relative to the detection component 20, the first detection module 21 can acquire an image of a first region on the material to be tested. When the supporting component is in a second position relative to the detection component 20, the second detection module 22 can acquire an image of a second region on the material to be tested. When the supporting component is in a third position relative to the detection component 20, the third detection module 23 can acquire an image of a third region on the material to be tested. The second and third regions are located on opposite sides of the first region. Therefore, the detection component 20 can perform multi-region detection on the material to be tested, and multi-dimensional detection of the material to be tested can be achieved through the relative movement of the supporting component and the detection component 20. Using this detection device 1 for shape detection of the material to be tested results in simpler and more convenient operation, shorter detection time, and lower overall cost.

[0042] In one embodiment of the present invention, see Figure 2 , Figure 3 , Figure 4 and Figure 5At least one of the second detection module 22 and the third detection module 23 can be configured as a bidirectional detection assembly 24. The bidirectional detection assembly 24 can include a first lateral detection element 241 and a second lateral detection element 242. The detection directions of the first lateral detection element 241 and the second lateral detection element 242 can be opposite to each other or at a certain angle. Taking the second detection module 22 configured as the bidirectional detection assembly 24 as an example, when the material to be tested is in a second position relative to the detection assembly 20, the first lateral detection element 241 and the second lateral detection element 242 in the bidirectional detection assembly 24 can detect the second region from two different angles, which can perform multi-size detection on the second region of the material to be tested. Especially when the second region of the material to be tested has a complex structure and multi-size detection requirements, such a second detection module 22 can meet the requirements. The third detection module 23 is configured as the bidirectional detection assembly 24 in a similar way, and will not be described in detail here. It is understood that both the second detection module 22 and the third detection module 23 can be configured as the bidirectional detection assembly 24. The second and third regions can each have a surface to be tested. In embodiments where the material to be tested is a battery casing, the surface to be tested can be a sidewall of the battery casing, and in this case, the surface to be tested can be a regular elongated panel structure. In other embodiments, the surface to be tested can also be any other suitable form, such as a curved surface. The surfaces to be tested located in the second and third regions can be the same or different. The surfaces to be tested in the second and third regions can be arranged opposite each other on both sides of the first region. The surfaces to be tested in the second and third regions can be parallel or at an angle to each other, and the relative positional relationship between the two surfaces to be tested can be determined by the specific form of the two surfaces to be tested. The surface to be tested can have an inner side facing the first region and an outer side away from the first region. The inner side of the surface to be tested in the second region can be opposite to the inner side of the surface to be tested in the third region. Similarly, it is not limited that the two inner sides are parallel; depending on the different forms of the two surfaces to be tested, the two inner sides can have any positional relationship. The first lateral detection element 241 can be used to acquire an image of the inner side, and the second lateral detection element 242 can be used to acquire an image of the outer side. For the material to be tested in the second region with a surface to be tested, the second detection module 22 can be configured as a bidirectional detection component 24 to detect the inner and outer sides of the surface to be tested in the second region respectively; for the material to be tested in the third region with a surface to be tested, the third detection module 23 can be configured as a bidirectional detection component 24 to detect the inner and outer sides of the surface to be tested in the third region respectively.When such a detection device 1 is used, even if different areas of the material to be tested have different complex structures, it can perform multi-angle detection on the complex structures in the area, which can meet the multi-size detection needs of more types of materials to be tested, and the overall applicability can be wider; moreover, since such a detection device 1 can perform multi-angle detection on some areas of the material to be tested, the detection effect can be better.

[0043] For example, see Figure 3 , Figure 4 and Figure 5The bidirectional detection assembly 24 may further include a base 243, and the first lateral detection element 241 and the second lateral detection element 242 may be adjustablely connected to the base 243. By setting the base 243 in a suitable position, the bidirectional detection assembly 24 can be installed in a suitable location. The first lateral detection element 241 and the second lateral detection element 242 may be adjustablely connected to the base 243 through the same connection structure, or they may be adjustablely connected to the base 243 through different connection structures. Taking the adjustable connection of the first lateral detection element 241 to the base 243 as an example, "adjustable connection" means that the relative positional relationship between the first lateral detection element 241 and the base 243 can be changed. Specifically, the first lateral detection element 241 may be movable relative to the base 243, or it may be rotatable relative to the base 243. Depending on the connection structure, the first lateral detection element 241 can be adjusted relative to the base 243 in various ways. For example, the first lateral detection element 241 can be connected to the base 243 via a rotating structure, thus allowing the first lateral detection element 241 to rotate relative to the base 243. The base 243 can be provided with a straight or curved guide rail, and the first lateral detection element 241 can also be slidably connected to the guide rail, allowing the first lateral detection element 241 to move linearly relative to the base 243 to adjust its relative position. The second lateral detection element 242 is adjusted to connect to the base 243 in a similar manner, and will not be described in detail here. The form in which the first lateral detection element 241 is adjustablely connected to the base 243 can be the same as or different from the form in which the second lateral detection element 242 is adjustablely connected to the base 243. Therefore, the relative positional relationship adjustment that the first lateral detection element 241 can achieve relative to the base 243, and the relative positional relationship adjustment that the second lateral detection element 242 can achieve relative to the base 243, can be achieved in the same or different ways. This detection device 1, based on the ability to perform multi-angle detection of specific areas of the material to be tested, can achieve better detection angles for specific areas of the material to be tested by adjusting the relative positions and angles of the first lateral detection element 241 and the base 243, and by adjusting the relative positions and angles of the second lateral detection element 242 and the base 243. This results in better detection performance and can meet the special needs of multi-size detection of different materials to be tested. For example, the specific area of ​​the material to be tested can be a second area or a third area of ​​the material to be tested.For example, for a material to be tested in the second region with a surface to be tested, the second detection module 22 can be configured as a bidirectional detection component 24. By adjusting the relative position and angle between the first lateral detection element 241 and the base 243, and by adjusting the relative position and angle between the second lateral detection element 242 and the base 243, the first lateral detection element 241 and the second lateral detection element 242 can achieve better detection results for any type of surface to be tested. The process is similar for a material to be tested in the third region with a surface to be tested, and will not be elaborated upon here.

[0044] For example, see Figure 3 , Figure 4 and Figure 5 The bidirectional detection assembly 24 may further include a connector 244, an adjusting member 245, and a rotating member 246. The connector 244 is movably connected to the base 243 along a first direction (direction XX in the figure). The adjusting member 245 is movably connected to the connector 244 along a second direction (direction YY in the figure). The rotating member 246 is rotatable about the first direction XX and movably connected to the adjusting member 245 along a third direction (direction ZZ in the figure). At least one of the first lateral detection member 241 and the second lateral detection member 242 can be connected to the rotating member 246 and rotatable about the first direction XX. The first direction XX, the second direction YY, and the third direction ZZ can form certain angles with each other. The connector 244 can be movably connected to the base 243 along the first direction XX in any suitable manner. See [reference needed]. Figure 3 , Figure 4 and Figure 5 The base 243 may have multiple connecting holes along the first direction XX. By connecting the connector 244 to different connecting holes, the connector 244 can be movably connected to the base 243 along the first direction XX. In an embodiment not shown, the base 243 may also have a guide rail extending along the first direction XX, and the connector 244 can be slidably connected to the guide rail extending along the first direction XX, thus also enabling the connector 244 to be movably connected to the base 243 along the first direction XX. The adjusting member 245 can be movably connected to the connector 244 along the second direction YY in any suitable form, see [reference]. Figure 4 and Figure 5The connector 244 may have multiple connecting holes along the second direction YY. By connecting the adjusting member 245 to different connecting holes, the adjusting member 245 can be movably connected to the base 243 along the second direction YY. In an embodiment not shown, the connector 244 may have multiple slots arranged along the second direction YY. By snapping the adjusting member 245 to different slots, the adjusting member 245 can be movably connected to the connector 244 along the second direction YY. The rotating member 246 can be movably connected to the adjusting member 245 along a third direction ZZ in any suitable manner, such as... Figure 4 and Figure 5As shown, the adjusting member 245 may be provided with a mating groove extending along the third direction ZZ. The rotating member 246 may be connected to a connecting plate 247, which may be provided with multiple connecting holes. By fasteners passing through the connecting holes and the mating groove, the connecting plate 247 can be connected to different positions on the mating groove, thereby enabling the rotating member 246 to be movably connected to the adjusting member 245 along the third direction ZZ. The rotating member 246 can be rotatably connected to the connecting plate 247 around the first direction XX, thus enabling the rotating member 246 to be rotatably connected to the adjusting member 245 around the first direction XX. This rotatable connection of the rotating member 246 around the first direction XX to the connecting plate 247 can be achieved by a rotating shaft passing through both the rotating member 246 and the connecting plate 247. In an embodiment not shown, the adjusting member 245 may be provided with a connecting groove extending along the third direction ZZ, and the rotating member 246 may be connected to a rotating shaft extending along the first direction XX. By connecting the rotating shaft to different positions on the connecting groove, the rotating member 246 can be movably connected to the adjusting member 245 along the third direction ZZ. Simultaneously, since the rotating member 246 can rotate around the rotating shaft, it can also rotate around the first direction XX. The first direction XX, the second direction YY, and the third direction ZZ can form any suitable angle with each other. Taking the connection of the first lateral detection element 241 to the rotating element 246 as an example, the connecting element 244 is movably connected to the base 243 along the first direction XX, thus enabling the first lateral detection element 241 to move along the first direction XX; the adjusting element 245 is movably connected to the connecting element 244 along the second direction YY, thus enabling the first lateral detection element 241 to move along the second direction YY; the rotating element 246 is rotatable around the first direction XX and movably connected to the adjusting element 245 along the third direction ZZ, thus enabling the first lateral detection element 241 to move along the third direction ZZ and rotate around the first direction XX. In this way, the first lateral detection element 241 can move along the first direction XX, the second direction YY, and the third direction ZZ, and can rotate around the first direction XX. Understandably, through proper design, the first lateral detection element 241 can detect the material under test at any position and angle in three-dimensional space, thus meeting the need for multi-dimensional detection of materials of any complex form. The connection between the second lateral detection element 242 and the rotating element 246 is similar and will not be elaborated here. This detection device 1, by adjusting the position and angle of the first lateral detection element 241 and / or the second lateral detection element 242, can achieve multi-dimensional detection of materials of any form, thereby meeting the needs for multi-dimensional detection of more materials. This not only broadens the applicability of the overall device but also improves the detection effect.Moreover, by making the first lateral detection element 241 and / or the second lateral detection element 242 adjustablely connected to the base 243 in this form, the overall structure is simpler and easier to manufacture.

[0045] For example, the first direction XX, the second direction YY, and the third direction ZZ can be perpendicular to each other. When the first direction XX, the second direction YY, and the third direction ZZ are perpendicular to each other, they can form a spatial rectangular coordinate system. This makes adjusting the position of the first lateral detection element 241 and / or the second lateral detection element 242 simpler and easier to operate. Moreover, when the first direction XX, the second direction YY, and the third direction ZZ are perpendicular to each other, the structure of the connecting element 244, the adjusting element 245, and the rotating element 246 can be simpler, and the connection between them can also be simpler, thus making the overall structure simpler and easier to implement.

[0046] For example, see Figure 1 and Figure 2The detection device 1 may include a base frame 30, and a base 243 may be connected to the base frame 30 and movable relative to the base frame 30 along a second direction YY. The base frame 30 may be installed at any suitable location so that the detection device 1 may be installed at any suitable location. The base 243 may be movably connected to the base frame 30 along the second direction YY in any suitable manner. In the embodiment shown in the figure, the base frame 30 may be provided with a guide rail extending along the second direction YY, and the base 243 may be slidably connected to the guide rail, thereby the base 243 may be movably connected to the base frame 30 along the second direction YY. When the base 243 is movably connected to the base frame 30 along the second direction YY, the bidirectional detection assembly 24 as a whole is movable relative to the base frame 30 along the second direction YY. Taking the second detection module 22 configured as a bidirectional detection component 24 as an example, the carrier component carries the material to be tested and moves relative to the detection component 20. When the material to be tested is in the second position relative to the detection component 20, the position of the bidirectional detection component 24 relative to the base frame 30 can be adjusted so that the bidirectional detection component 24 can better detect the second area on the material to be tested. During the detection process, the position of the bidirectional detection component 24 relative to the base frame 30 along the second direction YY can also be adjusted. Thus, for any type of material to be tested, the bidirectional detection component 24 can perform multi-size detection. The third detection module 23 configured as a bidirectional detection component 24 is similar and will not be described in detail here. For example, when the direction of relative movement between the detection component 20 and the carrier component is a straight line, the direction of relative movement can be perpendicular to the second direction YY. For example, the detection component 20 and the carrier component can move relative to each other along the first direction XX, and the first direction XX can be perpendicular to the second direction YY. This makes the position adjustment of the bidirectional detection component 24 relative to the base frame 30 simpler. By adjusting the position of the base 243 relative to the base frame 30 along the second direction YY, the bidirectional detection component 24 can detect the material to be tested from a better position and angle. Moreover, the bidirectional detection component 24 can perform multi-dimensional detection on various forms of the material to be tested. Thus, the detection device 1 as a whole can be applied to multi-dimensional detection on more forms of the material to be tested, with a wider range of applications and better detection results.

[0047] In one embodiment of the present invention, see Figure 1 and Figure 2The first detection module 21 can have a light-emitting surface, which can be configured to emit detection light rays in a vertical direction. The detection component 20 can be positioned above the supporting component, so that the detection component 20 can be positioned above the material to be tested to perform the detection. The first detection module 21 emits detection light rays in a vertical direction, which can detect the entire material to be tested or the planar portion of the material to be tested. Taking a battery casing as an example, such a first detection module 21 can detect the bottom wall portion of the battery casing. It is understood that regardless of the form of the material to be tested, at least a portion of the structure on the material to be tested can be detected using vertical detection light rays. Since the first detection module 21 is configured to emit detection light rays in a vertical direction, the structure of the first detection module 21 can be simpler, and the overall structure of the detection device 1 can also be simpler. Moreover, such a first detection module 21 is easier to operate. Such a detection device 1 can perform the detection of the material to be tested more simply, the time required to complete the detection can be shorter, the overall structure is simpler, and thus the overall cost can be lower.

[0048] In one embodiment of the present invention, the detection device 1 may include a conveying component, which can be used to convey a carrier component along a predetermined detection path. A first position, a second position, and a third position can be sequentially located on the predetermined detection path. By moving the conveying component, the carrier component can be moved, thereby enabling relative movement between the carrier component and the detection component 20. The carrier component can move with the conveying component, allowing the detection component 20 to remain stationary; that is, the detection component 20 can be fixedly installed. This simplifies the installation of the detection component 20, simplifies the overall structure, and lowers the overall cost. Furthermore, by moving the carrier component to achieve relative movement between the carrier component and the detection component 20, the operation of the detection process is also simplified.

[0049] In one embodiment of the present invention, the detection device 1 may include a base frame 30 and a fixedly mounted platform. The detection component 20 may be mounted on the base frame 30, and the base frame 30 may be movably connected to the mounting platform along a predetermined detection path. A support component may be fixedly mounted on the mounting platform. By moving the base frame 30, the detection component 20 can be moved, thereby enabling relative movement between the detection component 20 and the support component. Since the support component is fixedly mounted, the material to be tested remains stationary during the detection process. Thus, the detection of the material to be tested can be completed simply by moving the detection component 20, which better protects the material to be tested and prevents it from falling or being damaged during movement.

[0050] In one embodiment of the present invention, the bearing component may have a rotating structure, which can be used to drive the material to be tested to rotate by a specified angle to form a rotated material. The material to be tested may also have a fourth region and a fifth region, which may be located on both sides of the first region, and the second, third, fourth, and fifth regions may be located on the periphery of the first region. The second detection module 22 may be used to acquire an image of the fourth region when the rotated material is in a second position relative to the detection component 20, and the third detection module 23 may be used to acquire an image of the fifth region when the rotated material is in a third position relative to the detection component 20. For materials to be tested with complex structures, simply dividing the material to be tested into a first, second, and third region cannot meet the requirements for multi-size detection. In this case, the material to be tested can be divided into a first, second, third, fourth, and fifth region. It is understood that through a simple design, after dividing the material to be tested into a first, second, third, fourth, and fifth region, the first, second, third, fourth, and fifth regions can be detected separately to complete the detection of the material to be tested. Regions 1, 2, 3, 4, and 5 are simply five regions defined on the material to be tested. This division is solely for ease of differentiation and to facilitate zonal testing of the material; no special structure is required on the material to distinguish these regions. Regions 2, 3, 4, and 5 are located around Region 1 and can be arranged sequentially in a counter-clockwise direction around Region 1. Taking a battery casing as an example, the casing can have four sequentially connected sidewalls and a bottom wall. For such a casing, the bottom wall can be considered to be located within Region 1, and the four sequentially connected sidewalls can be located sequentially within Regions 2, 3, 4, and 5, respectively. This effectively means that each of Regions 2, 3, 4, and 5 has a surface to be tested. Although a fourth and fifth region have been added here, the detection of the fourth and fifth regions is similar to the detection of the second and third regions described above. Similarly, the detection of the surfaces to be detected in the fourth region and the fifth region is similar to the detection of the surfaces to be detected in the second and third regions described above, and will not be repeated here.Since the second, third, fourth, and fifth regions can be located around the periphery of the first region, after the material to be tested is rotated, when the material to be tested is in the second position relative to the detection component 20, the detection of the second region by the detection component 20 changes to the detection of the fourth region; when the material to be tested is in the third position relative to the detection component 20, the detection of the third region changes to the detection of the fifth region. Thus, the material to be tested only needs to pass through three positions relative to the detection component 20 to complete the detection of all five regions on the material to be tested. Taking the second, fifth, third, and fourth regions arranged sequentially around the periphery of the first region in a counter-clockwise direction as an example, the rotation of the material to be tested can be in a counter-clockwise direction. It is understood that dividing the material to be tested into five regions is only an example. In embodiments not shown, the material to be tested can also be divided into six, seven, or any other number of regions. Through reasonable design of the relative movement path between the supporting component and the detection component 20, and by using a rotating structure to drive the material to be tested to rotate, multi-size detection of the material to be tested can be achieved. Such a detection device 1 can detect more areas of the material to be tested, thereby enabling multi-size detection of various forms of the material to be tested, and its overall applicability is wider.

[0051] According to another aspect of the present invention, a detection method is provided for any of the detection devices 1 described above, see [link to previous document]. Figure 6 The detection method may include the following steps:

[0052] S10: Move the detection component 20 relative to the carrier component until the material to be tested is in a first position relative to the detection component 20, and obtain an image of the first area through the first detection module 21;

[0053] S20: Move the detection component 20 relative to the carrier component until the material to be tested is in a second position relative to the detection component 20, and obtain an image of the second region through the second detection module 22;

[0054] S30: Move the detection component 20 relative to the carrier component until the material to be tested is in a third position relative to the detection component 20, and obtain an image of the third region through the third detection module 23.

[0055] Taking the fixed installation of the detection component 20 in the detection device 1 and the movement of the carrier component relative to the detection component 20 along a predetermined detection path as an example, the first, second, and third positions of the material to be tested relative to the detection component 20 can be sequentially located on the predetermined detection path. When the carrier component carrying the material to be tested moves to the first position relative to the detection component 20, the first detection module 21 in the detection component 20 can acquire an image of the first area on the material to be tested; when the carrier component carrying the material to be tested moves to the second position relative to the detection component 20, the second detection module 22 in the detection component 20 can acquire an image of the second area on the material to be tested; when the carrier component carrying the material to be tested moves to the third position relative to the detection component 20, the third detection module 23 in the detection component 20 can acquire an image of the third area on the material to be tested. Since the first, second, and third positions are located on the predetermined detection path in sequence, the carrier component carrying the material to be tested only needs to move along the predetermined detection path to complete the multi-size detection of the material to be tested through the detection component 20. It is understandable that, since the first, second, and third positions are not limited to specific locations, when this detection method is applied to the detection device 1, it is only necessary for the carrier component to carry the material to be tested between the first, second, and third positions. For example, the carrier component can carry the material to be tested from the first position to the second position and then from the second position to the third position. The detection component 20 can then complete the multi-size detection of the material to be tested, resulting in a shorter overall detection time and simpler operation. Of course, in some embodiments, the carrier component can be fixedly installed, and the detection component 20 can move relative to the carrier component along a predetermined detection path, similar to the above, and will not be elaborated further here.

[0056] For example, see Figure 7 The material to be tested may also have a fourth and a fifth region, which may be located on either side of the first region. The second, third, fourth, and fifth regions may be located around the periphery of the first region. The detection method may include the following steps:

[0057] S40: After rotating the material to be tested in the carrier component by a specified angle to form the rotated material, the detection component 20 is moved relative to the carrier component again until the rotated material is in a second position relative to the detection component 20, and the image of the fourth region is obtained through the second detection module 22.

[0058] And / or, the detection method may include the steps of:

[0059] S50: Move the detection component 20 relative to the carrier component again until the material is in the third position relative to the detection component 20 after rotation, and obtain the image of the fifth region through the third detection module 23.

[0060] The material to be tested can have a first region, a second region, a third region, a fourth region, and a fifth region to meet the needs of multi-size detection on various types of materials. The detection of the fourth region on the material to be tested can be completed in step S40; the detection of the fifth region can be completed in step S50. Based on the detection method including steps S10, S20, and S30, the detection of the fourth and fifth regions on the material to be tested can be completed simply by rotating the material and allowing it to move between the first, second, and third positions, that is, by allowing the material to move relative to the detection component 20 along a predetermined detection path. This eliminates the need to set more detection positions for the material relative to the detection component 20, thus simplifying the detection process.

[0061] In one embodiment of the present invention, the detection component 20 is fixedly disposed, and the supporting component is movable relative to the detection component 20 along a predetermined detection path. The first, second, and third positions of the material to be tested relative to the detection component 20 are all located on the predetermined detection path. When detecting the material to be tested, the supporting component can first move the material to be tested to the first position relative to the detection component 20, at which point the first detection module 21 in the detection component 20 can detect the first area on the material to be tested; then the supporting component can move the material to be tested to the second position relative to the detection component 20, at which point the second detection module 22 in the detection component 20 can detect the second area on the material to be tested; subsequently, the supporting component can move the material to be tested to the third position relative to the detection component 20, at which point the third detection module 23 in the detection component 20 can detect the third area on the material to be tested. The third region on the material to be tested is inspected. After the inspection of the third region is completed, the material to be tested can be rotated by the carrier component. At this time, the material to be tested is still in the third position relative to the detection component 20. That is, after rotation, the material is in the third position relative to the detection component 20. The fifth region on the material to be tested can be inspected through the third detection module 23 in the detection component 20. Finally, the carrier component moves the material to be tested until it is in the second position relative to the detection component 20. At this time, the fourth region on the material to be tested can be inspected through the second detection module 22 in the detection component 20. In this way, the inspection of the first, second, third, fourth and fifth regions on the material to be tested can be completed, which can meet the multi-size inspection needs of various types of materials to be tested.
