Description

Technical Field

[0001] This application relates to the field of battery cell manufacturing technology, and in particular to a burr detection device and a burr detection method. Background Technology

[0002] In the production of lithium-ion and sodium-ion batteries, after coating and rolling processes, the electrode sheets typically need to be slit and wound up during transport. For the slit electrode sheets, it is usually necessary to inspect the burrs on the slit edges to prevent punctures and other problems in subsequent processes.

[0003] Related technologies typically use visual cameras to detect burrs on the sides of the slit electrodes, but sometimes burr recognition fails in the image, and the success rate of burr detection needs to be improved. Summary of the Invention

[0004] The main objective of this application is to propose a burr detection device aimed at improving the success rate of burr detection.

[0005] To achieve the above objectives, the burr detection device proposed in this application includes a guide rail assembly, a moving plate, a first driving device, a positioning module, a vision module, and a processing module. The guide rail assembly is configured to be mounted on a vertical plate, and the extension direction of the guide rail assembly is configured to be parallel to the width direction of the conveyor line, which is configured to convey slit electrode sheets. The moving plate is slidably connected to the guide rail assembly and is configured to move along the extension direction of the guide rail assembly. The first driving device is drively connected to the moving plate and is configured to move the moving plate. The positioning module is mounted on the moving plate and is configured to acquire the current position of the edge of the electrode sheet. The vision module is mounted on the moving plate and is configured to acquire an image of the edge of the electrode sheet. The processing module is electrically connected to the positioning module, the first driving device, and the vision module. The processing module is configured to drive the first driving device according to the current position of the edge of the electrode sheet, and is also configured to identify burrs according to the image of the edge of the electrode sheet.

[0006] The burr detection equipment in this application, when in use, can determine the offset of the conveyed electrode in the width direction by obtaining the current position of the electrode edge through the positioning module. This allows the vision module to move accordingly to the electrode offset via the first driving device and the moving plate. This reduces the risk of the electrode edge falling out of the depth of field of the vision module, reduces the risk of blurred imaging by the vision module, and improves the success rate of burr detection. Furthermore, the positioning module can also move accordingly to the electrode offset via the first driving device and the moving plate, reducing the risk of the electrode edge falling out of the positioning module and making the burr detection equipment suitable for electrode cutting processes with larger offsets.

[0007] Optionally, the conveyor line includes an abutment portion in the width direction, the abutment portion being used to abut the electrode sheet; the vision module includes a light source assembly and an imaging assembly, the light source assembly and the imaging assembly being fixed to the moving plate respectively, the light source assembly and the imaging assembly being respectively disposed between the abutment portion of the conveyor line and the upright plate, and the light source assembly being configured to emit light in a direction away from the imaging assembly.

[0008] At this point, the light source assembly is configured to emit light in a direction away from the imaging assembly, thereby improving the brightness and imaging contrast of the electrode edge, which is beneficial for improving the imaging clarity of the vision module. Furthermore, the light source assembly and imaging assembly are respectively positioned between the contact portion of the conveyor line and the upright plate, which helps reduce the length of the guide rail assembly parallel to the width direction of the conveyor line, reduces the overhang length of the guide rail assembly, improves the movement stability of the moving plate and positioning module, and the vision module, as well as the positional accuracy before and after movement, thus improving the imaging clarity of the vision module and further enhancing the success rate of burr detection.

[0009] Optionally, the light source assembly includes a ring light source configured to emit light in a direction away from the shooting assembly; the shooting assembly includes a telecentric lens and a camera, one end of the telecentric lens being disposed opposite to the ring light source, and the other end of the telecentric lens being disposed opposite to the camera.

[0010] At this point, the light emitted by the ring light source can more evenly illuminate the edge of the electrode, which helps to highlight the difference between burrs and the carbon powder and other materials on the electrode, and improves the imaging contrast of the electrode edge. Furthermore, since the vision module can reduce the risk of the electrode edge falling out of the depth of field by moving, the burr detection equipment can use a telecentric lens with a smaller depth of field, thereby improving image clarity and reducing image distortion, which further enhances the success rate of burr detection.

[0011] Optionally, the shooting assembly includes a telecentric lens and a camera, one end of the telecentric lens being disposed opposite to the light source assembly, and the other end of the telecentric lens being disposed opposite to the camera; the shooting assembly also includes a reflector, which is disposed between the abutting portion of the conveyor line and the telecentric lens, and the reflector is configured to reflect light from the electrode into the telecentric lens.

[0012] At this point, the telecentric lens can work with the reflex mirror to facilitate camera imaging.

[0013] Optionally, the reflector is disposed between the light source assembly and the telecentric lens; the imaging assembly further includes a connecting shell, which is disposed between the light source assembly and the telecentric lens, and the reflector is disposed inside the connecting shell; the connecting shell has a first opening and a second opening, the end of the telecentric lens covers the first opening of the connecting shell, and the end of the telecentric lens abuts against the connecting shell; the light source assembly includes an annular light source, the internal space of the annular light source is disposed opposite to the second opening of the connecting shell, and the axial end of the annular light source abuts against the connecting shell.

[0014] At this point, the reflector is positioned inside the connecting housing, which helps reduce the risk of foreign objects such as burrs falling from the site adhering to the reflector, thus improving image clarity. Furthermore, the end of the telecentric lens abuts against the connecting housing, and the axial end of the ring light source abuts against the connecting housing, respectively, which helps improve the positional stability of the telecentric lens and the ring light source before and after movement, further enhancing image clarity.

[0015] Optionally, the light source component is configured as a strobe light source, the processing module is electrically connected to the light source component, and the processing module is configured to make the light source component turn on and off according to a preset timing sequence.

[0016] At this point, the light source assembly is set as a strobe light source, which provides higher brightness to the edge of the electrode, further improving imaging contrast and increasing the success rate of burr detection. Furthermore, the processing module is configured to turn the light source assembly on and off according to a preset time sequence, allowing the strobe light source to be extinguished during the imaging interval. This reduces the continuous operating time of the high-brightness strobe light source and extends the lifespan of both the strobe light source and the burr detection equipment.

[0017] Optionally, the light source component and the shooting component of the vision module are respectively fixed to the movable plate; one end of the telecentric lens of the shooting component is disposed opposite to the light source component of the shooting component, and the other end of the telecentric lens is disposed opposite to the camera; the movable plate is provided with an adjustment plate and an adjustment component, the adjustment plate is disposed between the camera and the movable plate, and the adjustment plate abuts against the camera; one end of the adjustment component is connected to the movable plate, the other end of the adjustment component is connected to the adjustment plate, and the adjustment component is configured to move the adjustment plate closer to or further away from the movable plate.

[0018] At this point, the adjustment plate positioned between the camera and the moving plate can be moved to more securely contact the camera via the adjustment components, which helps improve the camera's positional stability before and after movement and further enhances image clarity.

[0019] Optionally, the movable plate includes a first straight section, a first vertical section, and a second straight section connected in sequence, wherein the first straight section, the first vertical section, and the second straight section are arranged in the direction from the telecentric lens to the camera; the distance from the first straight section to the telecentric lens is less than the distance from the second straight section to the telecentric lens, and the camera is arranged opposite to the second straight section; the adjustment plate is disposed between the camera and the second straight section, and one end of the adjustment component is connected to the second straight section.

[0020] At this point, the distance from the first flat section to the telecentric lens is less than the distance from the second flat section to the telecentric lens. The camera is positioned relative to the second flat section, which helps to provide more installation space for the camera at the second flat section of the moving plate and facilitates the use of a camera with a larger imaging sensor to further improve image clarity.

[0021] Optionally, the guide rail assembly includes a first guide rail and a second guide rail spaced apart, the extension direction of the first guide rail being parallel to the extension direction of the second guide rail, and the extension directions of the first guide rail and the second guide rail being configured to be parallel to the width direction of the conveyor line; a fixing component is provided on the moving plate, and the fixing component is fixedly connected to the telecentric lens; the first guide rail is disposed opposite to the fixing component, and the first guide rail is slidably connected to the side of the moving plate opposite to the fixing component; the second guide rail is disposed opposite to the camera, and the second guide rail is slidably connected to the side of the moving plate opposite to the camera.

[0022] At this point, the spaced-apart first and second guide rails improve the stability of the moving plate, positioning module, and vision module, as well as their positional accuracy before and after movement, thus further enhancing image clarity. The first guide rail, positioned relative to the fixed components on the moving plate, further improves the stability of the telecentric lens's movement and its positional accuracy before and after movement, also contributing to improved image clarity. The second guide rail, positioned relative to the camera, further improves the stability of the imaging sensor within the camera, as well as its positional accuracy before and after movement, again contributing to improved image clarity.

[0023] Optionally, the burr detection device further includes a fixing plate, which is fixedly connected to the upright plate; the first driving device and the guide rail assembly are respectively fixedly connected to the fixing plate, and the guide rail assembly is spaced apart from the upright plate in the length direction.

[0024] At this point, the fixed plate and the upright plate are fixedly connected, which improves the positional stability of the first driving device and the guide rail assembly on the fixed plate. This is beneficial for improving the movement stability and positional accuracy of the moving plate, positioning module, and vision module before and after movement, and further enhances image clarity. Furthermore, the guide rail assembly is spaced apart from the upright plate along its length, which reduces interference from the upright plate on the guide rail assembly during installation. This improves the installation positional accuracy of the guide rail assembly, further enhancing the positional accuracy of the moving plate, positioning module, and vision module before and after movement, and ultimately improving image clarity.

[0025] Optionally, the burr detection device further includes an inspection object and a second driving device. The second driving device is fixedly connected to the moving plate, and the inspection object is driven by the second driving device. The second driving device is configured to move the inspection object, and the direction of movement of the inspection object forms an angle with the optical axis direction of the image acquisition end of the vision module. The processing module is electrically connected to the second driving device to drive the second driving device.

[0026] At this point, the second drive device is fixedly connected to the moving plate, and the object to be inspected is driven by the second drive device. This allows the object to be inspected and the vision module to move simultaneously on the moving plate, which improves the relative positional accuracy between the object and the vision module, and also improves the repeatability accuracy in multiple inspections. Furthermore, the second drive device is configured to make an angle between the direction of movement of the object to be inspected and the optical axis of the image acquisition end of the vision module. This facilitates the removal of the object after inspection, reducing interference between the object and the photographing electrode, and improving the space utilization of the burr inspection equipment with inspection capabilities.

[0027] Optionally, the burr detection device further includes a conveyor line, wherein the positioning module and the vision module are spaced apart in the conveying direction of the conveyor line, and the conveyor line is configured to convey the electrode sheet from the positioning module to the vision module.

[0028] At this time, the transmission line is configured to transport the electrode sheet from the positioning module to the vision module, which helps to allow more processing time for the processing module to process the position information of the electrode sheet's edge, and helps to improve the driving accuracy of the processing module in driving the first driving device according to the current position of the electrode sheet's edge.

[0029] Optionally, the conveyor line includes a first roller, a second roller, and a third roller arranged sequentially at intervals, and the conveyor line is configured to convey the electrode sheet in a direction from the first roller to the second roller; the interval between the first roller and the second roller is arranged opposite to the positioning module, and the interval between the second roller and the third roller is arranged opposite to the vision module.

[0030] At this time, the first, second, and third rollers, which are arranged at intervals, can leave more processing time for the processing device by reducing the time consumed by the transmission of the electrode sheet. In addition, the positioning module can obtain the current position of the edge of the electrode sheet by the interval between the first and second rollers, and the vision module can obtain the image of the edge of the electrode sheet by the interval between the second and third rollers. This improves the utilization rate of the internal space of the transmission line by the positioning module and the vision module, and helps to improve the structural compactness of the burr detection equipment.

[0031] Optionally, a first arrangement direction is formed between the first roller and the second roller, and a second arrangement direction is formed between the second roller and the third roller, wherein the angle between the first arrangement direction and the second arrangement direction is greater than 0 degrees.

[0032] At this point, the area between the first, second, and third rollers can accommodate electrode sheets with a longer total length, which improves the buffering capacity of the conveyor line for electrode sheets and enhances the structural compactness of the burr detection equipment.

[0033] Optionally, the positioning module, the light source component of the vision module, and the shooting component of the vision module are arranged in sequence, the moving plate passes through the gap between the second roller and the third roller, the positioning module is disposed on the side of the second roller facing the first roller, and at least part of the shooting component is disposed on the side of the second roller facing away from the first roller.

[0034] At this point, the moving plate passes through the gap between the second and third rollers, thereby further improving the utilization rate of the internal space of the conveyor line and enhancing the structural compactness of the burr detection equipment. Furthermore, the burr detection equipment can shield the positioning module or imaging component through the conveying electrode, reducing interference from falling burrs and other foreign objects on the positioning module or the imaging component.

[0035] Optionally, the positioning module includes a signal transmitting part, a connecting part, and a signal receiving part connected in sequence, the connecting part being connected to the moving plate; the connecting part passing between the first roller and the second roller; the signal transmitting part and the signal receiving part being spaced apart, the gap between the signal transmitting part and the signal receiving part being configured to allow the electrode to pass through.

[0036] At this point, the positioning module can quickly obtain the current position of the electrode edge by receiving the signal emitted by the signal transmitting part through the signal receiving part. Furthermore, the connecting part passes through the gap between the first and second rollers, and the gap between the signal transmitting and receiving parts is configured to allow the electrode to pass through. This connection part further improves the utilization rate of the internal space of the conveyor line, which is beneficial for further improving the structural compactness of the burr detection equipment. In addition, the burr detection equipment can block the signal transmitting or receiving parts with the conveying electrode, reducing the interference of falling burrs and other foreign objects on the positioning module's positioning.

[0037] Optionally, the connecting portion of the positioning module is disposed between the abutting portion of the transmission line and the upright plate, and the two ends of the connecting portion are respectively connected to the signal transmitting portion. The signal transmitting portion, the connecting portion, and the signal receiving portion form an opening structure. The opening structure is disposed on the side of the connecting portion facing away from the upright plate, and the opening structure is configured to allow the electrode to pass through.

[0038] At this time, the opening structure formed by the signal transmitting part, the connecting part and the signal receiving part is set on the side of the connecting part facing away from the upright plate, so that after the burr detection equipment and the transmission line are connected, the electrode can pass through the gap between the signal transmitting part and the signal receiving part relatively quickly through the opening structure, which improves the ease of use of the burr detection equipment.

[0039] This application also proposes a burr detection method, which includes the following steps: Transmit the slit electrode sheets; Get the current position of the edge of the electrode; The focal length is adjusted by adjusting the distance between the visual module and the edge of the current electrode based on the current position of the electrode edge. An image is obtained by taking a picture of the edge of the electrode along its width. Burrs are identified based on images of the edges of the electrode.

[0040] The burr detection method in this application can determine the offset of the transmitted electrode in the width direction by obtaining the current position of the electrode edge. In this way, the distance between the vision module and the current electrode edge can be adjusted according to the electrode offset to adjust the focal length. This helps to reduce the risk of the electrode edge falling out of the depth of field of the vision module, reduces the risk of the vision module image blurring, and improves the success rate of burr detection.

[0041] Optionally, the step of adjusting the focal length by adjusting the distance between the visual module and the edge of the current electrode based on the current position of the electrode edge includes: Get the current position and the offset of the pre-stored position of the edge of the electrode; Based on the offset, the amount of movement of the visual module along the width direction of the electrode is obtained; The focal length is adjusted by adjusting the distance between the visual module and the edge of the current electrode based on the amount of movement.

[0042] At this point, the burr detection method can improve the driving efficiency of adjusting the distance between the visual module and the edge of the current electrode by obtaining the position offset of the electrode and the movement of the visual module along the width direction of the electrode, thereby improving the overall execution efficiency of the burr detection method.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0048] It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0050] In the production of lithium-ion and sodium-ion batteries, after coating and rolling processes, the electrode sheets typically need to be slit and wound up during transport. For the slit electrode sheets, it is usually necessary to inspect the burrs on the slit edges to prevent punctures and other problems in subsequent processes.

[0051] Related technologies typically use visual cameras to detect burrs on the sides of the slit electrodes, but sometimes burr recognition fails in the image, and the success rate of burr detection needs to be improved.

[0052] For electrode sheets in processes such as slitting, the conveying speed is usually quite high, reaching, for example, 2000 to 3000 millimeters per second. Furthermore, the accuracy requirements for detecting burrs on the sides of the slitted electrode sheets are high. Therefore, to meet the detection accuracy requirements, the image sensor of the vision module needs a large magnification, resulting in a very small depth of field for the vision module.

[0053] In actual production, the lateral vibration of the electrode sheet in the width direction during the conveying process can sometimes reach 10 mm; some electrode sheets are wider, and the corresponding conveyor lines of roller type are wider, resulting in greater lateral vibration of the electrode sheet; for example, the width of the electrode sheet before slitting can reach 1500 mm to 2000 mm, and the width of the corresponding electrode sheet after slitting can reach 500 to 1000 mm.

[0054] At this point, a large amount of lateral jitter can easily cause the edge of the electrode to fall out of the depth of field of the vision module. The imaging clarity of the vision module with a smaller depth of field is easily reduced, which can easily lead to the failure of burr recognition in the image. The success rate of burr detection needs to be improved.

[0055] Therefore, based on the above considerations, in order to improve the success rate of burr detection, this application proposes a burr detection device. When in use, this burr detection device can move the vision module accordingly based on the offset of the electrode in the width direction during transmission, thereby reducing the risk of the electrode edge falling out of the depth of field of the vision module, thus reducing the risk of blurred imaging in the vision module and improving the success rate of burr detection.

[0056] The structure of the burr detection device proposed in this application will be explained in detail below with specific implementation methods.

[0057] In one embodiment of this application, reference is made to Figure 1 and Figure 2 The burr detection device 100 includes a conveyor line 200. The conveyor line 200 can be understood as a linear structure capable of conveying the electrode sheet 201. The conveyor line 200 can be configured to include multiple rollers; for example, the conveyor line 200 may include a first roller 210, a second roller 220, and a third roller 230 arranged sequentially at intervals, thereby allowing more processing time for the processing unit and other modules of the burr detection device 100 by reducing the time consumed in conveying the electrode sheet 201. The conveyor line 200 can be configured to convey the electrode sheet 201 from the first roller 210 to the second roller 220; the conveying direction of the electrode sheet 201 can be referred to by the dotted arrow in the figure. Of course, the conveyor line 200 can also be configured to convey the electrode sheet 201 via a conveyor belt or other components; this embodiment does not limit this.

[0058] The aforementioned burr detection equipment 100 includes a guide rail assembly 110, a moving plate 120, a first driving device 130, a positioning module 140, a vision module 150, and a processing module. The guide rail assembly 110 is configured to be mounted on the upright plate 101, and its extension direction is configured to be parallel to the width direction of the conveyor line 200, which is configured to convey the slit electrode sheets 201. The moving plate 120 is slidably connected to the guide rail assembly 110 and is configured to move along the extension direction of the guide rail assembly 110. The first driving device 130 is drive-connected to the moving plate 120. 130 is configured to move the movable plate 120; a positioning module 140 is disposed on the movable plate 120 and is configured to acquire the current position of the edge of the electrode 201; a vision module 150 is disposed on the movable plate 120 and is configured to acquire an image of the edge of the electrode 201; a processing module is electrically connected to the positioning module 140, the first driving device 130, and the vision module 150 respectively; the processing module is configured to drive the first driving device 130 according to the current position of the edge of the electrode 201, and the processing module is also configured to identify burrs according to the image of the edge of the electrode 201.

[0059] The guide rail assembly 110 can be understood as a component consisting of at least one guide rail, and the guide rail assembly 110 is capable of guiding the component connected to it along its own extending direction, such as guiding the movable plate 120 in this embodiment. The extending direction of the guide rail assembly 110 is configured to be parallel to the width direction of the conveyor line 200, which can be understood as the extending direction of the guide rail assembly 110 being able to be positioned parallel to the width direction of the conveyor line 200, for example... Figure 1 The extension direction of the middle guide rail assembly 110 and the width direction of the transmission line 200 are parallel to the X-axis direction, respectively.

[0060] The guide rail assembly 110 can be indirectly connected to the upright plate 101 through other structures, or the guide rail assembly 110 can be directly connected to the upright plate 101. The connection methods include, but are not limited to, welding, snap-fitting, and connecting with fasteners such as bolts, so that the guide rail assembly 110 can be set on the upright plate 101.

[0061] The upright plate 101 can be understood as a relatively vertical plate, wall panel, or wall at the workstation. The burr detection equipment 100 may include the upright plate 101, thereby improving the connection stability of the guide rail assembly 110 and increasing the convenience of installing the burr detection equipment 100 at the workstation. Of course, the burr detection equipment 100 may also not include the upright plate 101. In this case, the burr detection equipment 100 can be installed on the upright plate 101 at the workstation through the guide rail assembly 110, for example, by installing the burr detection equipment 100 on a wall panel or wall-shaped upright plate 101 through the guide rail assembly 110.

[0062] The movable plate 120 can be understood as a plate that can move relative to the guide rail assembly 110. The movable plate 120 can support the positioning module 140 and the vision module 150. Guide grooves can be directly provided on the movable plate 120, or guide blocks with guide grooves can be provided on the movable plate 120, thereby enabling the movable plate 120 to move along the extension direction of the guide rail assembly 110 through the sliding connection between the guide grooves and the guide rail assembly 110.

[0063] The first driving device 130 is connected to the moving plate 120 through a transmission structure. This can be understood as the first driving device 130 being able to provide the moving power to the moving plate 120 through the transmission structure. For example, the first driving device 130 can be configured as a motor, electric push rod, cylinder, etc., and the transmission structure between the first driving device 130 and the moving plate 120 can be configured as a ball screw mechanism, crank-slider mechanism, four-bar mechanism, etc.

[0064] The positioning module 140 can be understood as being able to obtain the current position of the edge of the electrode 201. The positioning module 140 may include photoelectric sensors, ultrasonic sensors, infrared sensors, vision cameras, etc.

[0065] The vision module 150 can be understood as a module capable of acquiring an image and using that image for machine vision recognition. The vision module 150 can be configured to include an area scan camera or a line scan camera; wherein, the area scan camera sensor arranges the pixels in a matrix, and its sensor directly outputs a frame image after row exposure or frame exposure; the line scan camera sensor typically has only one row (or two to three rows) of pixels, and the line scan camera works in a manner similar to a scanner, and cyclically exposes the row pixels.

[0066] The processing module can be configured to include a host computer and a slave device. The host computer can be understood as a computer system with strong computing and data processing capabilities. It can be configured to handle complex algorithms, perform long-term data storage, and provide a graphical user interface for operation. Host computers include, but are not limited to, personal computers, industrial computers, or servers. The slave device is typically configured as a device or controller directly connected to hardware such as sensors and actuators in the control system. The slave device can be configured to execute specific control commands issued by the host computer, such as outputting switch signals, adjusting analog signals, and acquiring data. The hardware of the slave device typically includes microcontrollers, PLCs (Programmable Logic Controllers), embedded control boards, etc. In this case, the processing module, including the host computer and slave device, can convert the edge position signal of the electrode 201 obtained by the positioning module 140 into a drive signal for the first driving device 130. Furthermore, the processing module can employ existing image recognition technology to identify burrs in the edge image of the electrode 201, specifically through the aforementioned host computer. The processing module can also develop a burr recognition model through model training. The hardware connection relationships between the processing module and the first driving device 130, the positioning module 140, and the vision module 150 can be referenced... Figure 7 .

[0067] In use, the burr detection device 100 can transport the slit electrode sheet 201 via the conveyor line 200. For the electrode sheet 201 being transported, the current position of the edge of the electrode sheet 201 can be obtained through the positioning module 140. At this time, the processing module can determine the offset of the electrode sheet 201 in the width direction based on the current position of the edge of the electrode sheet 201, and then drive the first driving device 130 to move the vision module 150 parallel to the width direction of the electrode sheet 201. This can be understood as adjusting the focal length by adjusting the distance between the vision module 150 and the current edge of the electrode sheet 201. After the vision module 150 moves into position, it acquires an image of the edge of the electrode sheet 201. This can be understood as taking a picture of the edge of the electrode sheet 201 along the width direction of the electrode sheet 201. For the acquired image of the edge of the electrode sheet 201, the processing module identifies burrs based on the image of the edge of the electrode sheet 201, thereby realizing the edge burr detection of the electrode sheet 201.

[0068] In this embodiment, the burr detection device can determine the offset of the electrode 201 in the width direction by obtaining the current position of the edge of the electrode 201 through the positioning module 140. This allows the vision module 150 to move accordingly to the offset of the electrode 201 via the first driving device 130 and the moving plate 120. This reduces the risk of the edge of the electrode 201 falling out of the depth of field of the vision module 150, reduces the risk of blurred imaging by the vision module 150, and improves the success rate of burr detection. Furthermore, the positioning module 140 can also move accordingly to the offset of the electrode 201 via the first driving device 130 and the moving plate 120, reducing the risk of the edge of the electrode 201 falling out of the positioning module 140. This makes the burr detection device 100 suitable for electrode slitting operations with larger offsets.

[0069] Since the guide rail assembly 110 needs to support the weight of components such as the moving plate 120, the positioning module 140, and the vision module 150, when one end of the guide rail assembly 110 away from the upright plate 101 is suspended, the suspended end of the guide rail assembly 110 is prone to sagging under pressure after long-term use. When the moving plate 120 moves the same distance along the extension direction of the guide rail assembly 110, the horizontal movement components of the moving plate 120, the positioning module 140, and the vision module 150 become shorter. The positional accuracy of the moving plate 120, the positioning module 140, and the vision module 150 before and after movement needs to be further improved, thereby improving the imaging clarity of the vision module 150.

[0070] In some embodiments, the conveyor line 200 includes an abutment portion in the width direction for abutting the electrode 201; the vision module 150 includes a light source assembly 151 and an imaging assembly 152, which are respectively fixed to the movable plate 120 and respectively disposed between the abutment portion of the conveyor line 200 and the upright plate 101; the light source assembly 151 is configured to emit light in a direction away from the imaging assembly 152.

[0071] The abutting portion can be understood as the part of the transmission line 200 that abuts against the electrode 201 in the width direction. The abutting portion can also be understood as the part of the transmission line 200 that is covered by the electrode 201 in the width direction. For example... Figure 1 The portion of the transmission line 200 on the left side in the Y-axis direction.

[0072] The imaging component 152 can be understood as a component capable of capturing images of the edge of the electrode 201. The imaging component may include a camera and a corresponding lens. The light source component 151 and the imaging component 152 can be fixed to the movable plate 120 by means of fastening, binding with straps, or snapping. The light source component 151 is configured to emit light in a direction away from the imaging component 152. This can be understood as the light emitted by the light source component 151 reaching the electrode 201 and then being reflected back to the imaging component 152 to form an image.

[0073] The light source assembly 151 and the imaging assembly 152 are respectively disposed between the contact portion of the conveyor line 200 and the upright plate 101. This can be understood as the contact portion of the conveyor line 200, the light source assembly 151, and the upright plate 101 being arranged sequentially, and the contact portion of the conveyor line 200, the imaging assembly 152, and the upright plate 101 being arranged sequentially. In this configuration, the distance between the light source assembly 151 and the imaging assembly 152 and the upright plate 101 is closer than that between the contact portion of the conveyor line 200.

[0074] In this embodiment, the light source assembly 151 is configured to emit light in a direction away from the imaging assembly 152, thereby improving the brightness and imaging contrast of the edge of the electrode 201, which is beneficial to improving the imaging clarity of the vision module 150. Furthermore, the light source assembly 151 and the imaging assembly 152 are respectively positioned between the abutment portion of the conveyor line 200 and the upright plate 101, which helps to reduce the length of the guide rail assembly 110 parallel to the width direction of the conveyor line 200. This can be understood as the guide rail assembly 110 only needing to extend to the abutment portion of the conveyor line 200 at its shortest point. Therefore, this embodiment helps to reduce the overhang length of the guide rail assembly 110, improves the movement stability of the moving plate 120, the positioning module 140, and the vision module 150, as well as their positional accuracy before and after movement, thus improving the imaging clarity of the vision module 150 and further enhancing the success rate of burr detection.

[0075] When the electrode 201 has a high transmission speed, due to the thinness of the electrode 201, it is necessary to further improve the edge imaging clarity of the electrode 201.

[0076] In some implementations, refer to Figure 1 The light source assembly 151 can be configured to include a ring light source, and the angle between the axis of the ring light source and the width direction of the transmission line 200 can be set to less than 90 degrees. The ring light source is configured to emit light in a direction away from the shooting assembly 152. The shooting assembly 152 includes a telecentric lens 153 and a camera 154. One end of the telecentric lens 153 is positioned opposite to the ring light source, and the other end of the telecentric lens 153 is positioned opposite to the camera 154.

[0077] The ring light source can be understood as a light source that is circular in shape and emits light from multiple positions along the ring. The angle between the axis of the ring light source and the width direction of the transmission line 200 is less than 90 degrees, which can be understood as the axis of the ring light source not being perpendicular to the width direction of the transmission line 200 and the light emitted by the ring light source being generally directed towards the transmission line 200. The angle between the axis of the ring light source and the width direction of the transmission line 200 can be set to 0 degrees, 10 degrees, 20 degrees, etc. In some embodiments, the axis of the ring light source can be set to be parallel to the width direction of the transmission line 200, for example... Figure 1 The central axis of the ring light source is set along the Y-axis, and the width of the conveyor line 200 is also set along the Y-axis. One end of the telecentric lens 153 is positioned opposite the ring light source, and the other end is positioned opposite the camera 154, so that reflected light from the electrode 201 can pass through the telecentric lens 153 and enter the camera 154, where it is imaged by the imaging sensor. The telecentric lens offers better resolution and less image distortion than a conventional fixed-focus lens. In some embodiments, the camera 154 can be a high-resolution monochrome area array camera, such as one with 20 megapixels or higher, thereby improving the accuracy of burr detection.

[0078] In this embodiment, the light emitted by the ring light source can more evenly illuminate the edge of the electrode 201, which helps to highlight the difference between the burrs and the carbon powder or other materials of the electrode 201, and improves the imaging contrast of the edge of the electrode 201. Furthermore, since the vision module 150 can reduce the risk of the edge of the electrode 201 falling out of the depth of field of the vision module 150 by moving it, the burr detection device 100 can use a telecentric lens 153 with a smaller depth of field, thereby improving imaging clarity and reducing imaging distortion, which further improves the success rate of burr detection.

[0079] In addition, the light source assembly 151 can be configured as a strobe light source, and the processing module is electrically connected to the light source assembly 151. The processing module is configured to make the light source assembly 151 turn on and off according to a preset timing sequence.

[0080] The strobe light source can be understood as a light source capable of stroking and possessing high brightness. The processing module is configured to cause the light source component 151 to turn on and off according to a preset timing sequence. For example, the processing module can be connected to a light source controller (LSC) via a PLC, and the light source controller can then cause the light source component 151 to alternately turn on and off, thereby enabling the light source component 151 to provide high brightness when imaging is needed and to turn off when imaging is not needed. The aforementioned ring light source can be configured as a strobe light source.

[0081] In this embodiment, the light source assembly 151 is configured as a strobe light source, which provides higher brightness to the edge of the electrode 201, thereby improving imaging contrast and increasing the success rate of burr detection. Furthermore, the processing module is configured to turn the light source assembly 151 on and off according to a preset timing sequence, enabling the strobe light source to be extinguished during imaging intervals. This reduces the continuous operating time of the high-brightness strobe light source and extends the lifespan of both the strobe light source and the burr detection device 100.

[0082] Since the guide rail assembly 110 needs to support the weight of components such as the telecentric lens 153, the sag of the suspended end of the guide rail assembly 110 may increase after long-term use. It is necessary to further improve the positional accuracy of the moving plate 120, the positioning module 140, and the vision module 150 before and after movement, so as to improve the imaging clarity of the vision module 150.

[0083] In some implementations, refer to Figure 1 , Figure 2 and Figure 6 The angle between the length direction of the telecentric lens 153 and the width direction of the conveyor line 200 is greater than 0 degrees; the shooting assembly 152 also includes a reflector 155, which is disposed between the abutting part of the conveyor line 200 and the telecentric lens 153, and the reflector 155 is configured to reflect light on the electrode 201 into the telecentric lens 153.

[0084] The telecentric lens 153 is typically cylindrical, and its length direction can be understood as its axial direction. The angle between the length direction of the telecentric lens 153 and the width direction of the conveyor line 200 is greater than 0 degrees. This means the length direction of the telecentric lens 153 is not parallel to the width direction of the conveyor line 200, thus reducing the projected length of the telecentric lens 153 in the width direction of the conveyor line 200 and the corresponding size of the moving plate 120 in the width direction of the conveyor line 200. The angle between the length direction of the telecentric lens 153 and the width direction of the conveyor line 200 can be set to 90 degrees, 80 degrees, 70 degrees, etc. In some embodiments, the length direction of the telecentric lens 153 is perpendicular to the width direction of the conveyor line 200, for example... Figure 1 The telecentric lens 153 is positioned along the X-axis in length, and the conveyor line 200 is positioned along the Y-axis in width. In this configuration, the projected length of the telecentric lens 153 in the width direction of the conveyor line 200 is minimized, and the corresponding size of the moving plate 120 in the width direction of the conveyor line 200 is also minimized. Furthermore, the placement position and angle of the reflector 155 can be set according to the position of the telecentric lens 153, the position of the electrode 201, and the angle between the telecentric lens 153 in length and the electrode 201. This will not be elaborated upon in this embodiment.

[0085] In this embodiment, the telecentric lens 153 can cooperate with the reflector 155 to facilitate imaging by the camera 154. In addition, the angle between the length direction of the telecentric lens 153 and the width direction of the conveyor line 200 is greater than 0 degrees, which helps to reduce the space occupied by the long telecentric lens 153 in the width direction of the electrode 201. This helps to reduce the area of ​​the moving plate 120 and the overhang length of the guide rail assembly 110, improves the movement stability of the moving plate 120, the positioning module 140, and the vision module 150, as well as the positional accuracy before and after movement, and improves the imaging clarity of the vision module 150.

[0086] In other embodiments, the angle between the length direction of the telecentric lens 153 and the width direction of the transmission line 200 can also be set to 0 degrees, which facilitates the direct acquisition of light from the electrode 201 for imaging, reduces the use of the reflector 155, and helps to reduce the overall component cost.

[0087] When the electrode 201 is transported, slit, and wound, the burrs formed during slitting may fall off. These burrs may adhere to the reflector 155, which may reduce the image clarity of the image formed by the reflector 155.

[0088] In some embodiments, a reflector 155 is disposed between the light source assembly 151 and the telecentric lens 153; the imaging assembly 152 further includes a connecting housing 156, which is disposed between the light source assembly 151 and the telecentric lens 153, and the reflector 155 is disposed inside the connecting housing 156; the connecting housing 156 has a first opening and a second opening, the end of the telecentric lens 153 covers the first opening of the connecting housing 156, and the end of the telecentric lens 153 abuts against the connecting housing 156; the light source assembly 151 includes an annular light source, the internal space of the annular light source is disposed opposite to the second opening of the connecting housing 156, and the axial end of the annular light source abuts against the connecting housing 156.

[0089] The reflector 155 is positioned between the light source assembly 151 and the telecentric lens 153. This can be understood as the light source assembly 151, reflector 155, and telecentric lens 153 being arranged sequentially along the propagation path of the light used for imaging. The connecting housing 156 is also positioned between the light source assembly 151 and the telecentric lens 153. This can be understood as the light source assembly 151, connecting housing 156, and telecentric lens 153 being arranged sequentially along the propagation path of the light used for imaging. The reflector 155 can be mounted within the connecting housing 156 by adhesive, snap-fit, or plug-in methods, and the imaging light propagates through the first and second openings of the connecting housing 156. The end of the telecentric lens 153 covers the first opening of the connecting housing 156, thereby reducing the risk of light leakage from the gap between the first opening and the telecentric lens 153, which helps improve image quality. The internal space of the annular light source is positioned opposite the second opening of the connecting housing 156, meaning that the imaging light can pass sequentially through the internal space of the annular light source and the second opening of the connecting housing 156. The axial end of the ring light source abuts against the connecting shell 156, which helps to improve the abutment stability between the ring light source and the connecting shell 156 by abutting against the connecting shell 156 through the circumferential length of the ring light source.

[0090] In this embodiment, the reflector 155 is disposed within the connecting housing 156, which helps reduce the risk of foreign objects such as burrs falling from the site adhering to the reflector 155 and improves image clarity. Furthermore, the end of the telecentric lens 153 abuts against the connecting housing 156, and the axial end of the ring light source abuts against the connecting housing 156, respectively, which helps improve the positional stability of the telecentric lens 153 and the ring light source before and after movement, further enhancing image clarity.

[0091] Camera 154 is relatively large, and its position may change after repeated movements, which may lead to a decrease in image clarity.

[0092] In some embodiments, when one end of the telecentric lens 153 is positioned opposite to the light source assembly 151 (e.g., the aforementioned ring light source) and the other end of the telecentric lens 153 is positioned opposite to the camera 154, the movable plate 120 is provided with an adjustment plate 161 and an adjustment component 162. The adjustment plate 161 is positioned between the camera 154 and the movable plate 120 and abuts against the camera 154. One end of the adjustment component 162 is connected to the movable plate 120, and the other end of the adjustment component 162 is connected to the adjustment plate 161. The adjustment component 162 is configured to move the adjustment plate 161 closer to or further away from the movable plate 120.

[0093] The adjusting plate 161 can be understood as a plate that can be adjusted to the distance of the moving plate 120; the adjusting component 162 can be configured as a plug rod, bolt assembly, etc. For example, one end of the screw of the bolt assembly is threadedly connected to the moving plate 120, and the other end of the screw of the bolt assembly is axially fixed relative to the adjusting plate 161 and can rotate relative to the adjusting plate 161.

[0094] In this embodiment, the adjustment plate 161, which is disposed between the camera 154 and the moving plate 120, can be moved by the adjustment component 162 to more stably abut against the camera 154, which helps to improve the positional stability of the camera 154 before and after movement, and further improves the image clarity.

[0095] Conveyor line 200 typically includes multiple rollers and corresponding control cabinets and other components, so the available space at the installation site of conveyor line 200 is usually small. In addition, since components such as moving plate 120 and positioning module 140 need to be moved, the installation space available for camera 154 is small, which limits the size of the imaging sensor inside camera 154 and is not conducive to improving image clarity.

[0096] In some implementations, refer to Figure 2 or Figure 5 The movable plate 120 includes a first straight section 121, a first vertical section 122, and a second straight section 123 connected in sequence. The first straight section 121, the first vertical section 122, and the second straight section 123 are arranged in the direction from the telecentric lens 153 to the camera 154. The distance from the first straight section 121 to the telecentric lens 153 is less than the distance from the second straight section 123 to the telecentric lens 153. The camera 154 is arranged opposite to the second straight section 123. An adjustment plate 161 is disposed between the camera 154 and the second straight section 123. One end of the adjustment component 162 is connected to the second straight section 123.

[0097] The first straight section 121 and the second straight section 123 can be understood as the relatively straight parts of the moving plate 120 at the work station, and the first vertical section 122 can be understood as the relatively vertical parts of the moving plate 120 at the work station. The first straight section 121, the first vertical section 122 and the second straight section 123 can be integrally formed by stamping or other methods, or the first straight section 121, the first vertical section 122 and the second straight section 123 can be fixedly connected by welding, screws or other methods after being formed separately.

[0098] In this embodiment, the distance from the first straight section 121 to the telecentric lens 153 is less than the distance from the second straight section 123 to the telecentric lens 153. The camera 154 is arranged opposite to the second straight section 123, which is beneficial to provide more installation space for the camera 154 at the second straight section 123 of the moving plate 120, and is beneficial to use a camera 154 with a larger imaging sensor to further improve the imaging clarity.

[0099] With the inclusion of components such as the large-volume camera 154 and the large-area moving plate 120, the total weight borne by the guide rail assembly 110 increases, and the sag of the suspended end of the guide rail assembly 110 may increase after long-term use. Therefore, it is necessary to further improve the positional accuracy of the moving plate 120, the positioning module 140, and the vision module 150 before and after movement, thereby improving the imaging clarity of the vision module 150.

[0100] In some implementations, refer to Figure 2 or Figure 5 The guide rail assembly 110 includes a first guide rail 111 and a second guide rail 112 spaced apart. The extension direction of the first guide rail 111 is parallel to the extension direction of the second guide rail 112. The extension directions of the first guide rail 111 and the second guide rail 112 are respectively configured to be parallel to the width direction of the conveyor line 200. A fixing assembly 124 is provided on the moving plate 120. The fixing assembly 124 is fixedly connected to the telecentric lens 153. The first guide rail 111 is disposed opposite to the fixing assembly 124. The first guide rail 111 is slidably connected to the side of the moving plate 120 facing away from the fixing assembly 124. The second guide rail 112 is disposed opposite to the camera 154. The second guide rail 112 is slidably connected to the side of the moving plate 120 facing away from the camera 154.

[0101] The extension directions of the first guide rail 111 and the second guide rail 112 are respectively configured to be parallel to the width direction of the conveyor line 200. This can be understood as follows: when the burr detection device 100 is installed with the corresponding conveyor line 200, the extension directions of the first guide rail 111 and the second guide rail 112 can be positioned parallel to the width direction of the conveyor line 200. Furthermore, the fixing component 124 can be understood as a component capable of fixing the telecentric lens 153; for example, the fixing component 124 can be configured as a clamp, a clamp, or other structure.

[0102] In this embodiment, the spaced-apart first guide rail 111 and second guide rail 112 improve the movement stability and positional accuracy of the moving plate 120, positioning module 140, and vision module 150, thereby further enhancing image clarity. The first guide rail 111 is positioned opposite to the fixing component 124 on the moving plate 120, which further improves the movement stability and positional accuracy of the telecentric lens 153, thereby further enhancing image clarity. The second guide rail 112 is positioned opposite to the camera 154, which further improves the movement stability and positional accuracy of the imaging sensor within the camera 154, thereby further enhancing image clarity.

[0103] In the above embodiment, if the end of the guide rail assembly 110 is directly connected to the upright plate 101, the droop of the suspended end of the guide rail assembly 110 may be too large due to the limited connection strength between the end of the guide rail assembly 110 and the upright plate 101, which may result in a reduction in the imaging clarity of the visual module 150.

[0104] In some implementations, refer to Figure 3 , Figure 4 and Figure 5 The burr detection equipment 100 also includes a fixing plate 170, which is fixedly connected to the upright plate 101; the first driving device 130 and the guide rail assembly 110 are fixedly connected to the fixing plate 170 respectively, and the guide rail assembly 110 is spaced apart from the upright plate 101 in the length direction.

[0105] The fixing plate 170 can be understood as a plate fixed relative to the upright plate 101. The fixing plate 170 can be fixedly connected to the upright plate 101 by welding, bolts, or other fasteners. The guide rail assembly 110 is spaced apart from the upright plate 101 in the length direction. This can be understood as the ends of the guide rail assembly 110 in the length direction being spaced apart from the upright plate 101. For example, the first guide rail 111 and the second guide rail 112 mentioned above can be respectively set to be spaced apart from the upright plate 101 in the length direction. In this case, the fixing plate 170 can be fixed to the upright plate 101 first, and then the guide rail assembly 110 can be installed on the fixing plate 170, which facilitates the adjustment of the orientation of the guide rail assembly 110 during installation. The guide rail assembly 110 can be connected to the fixing plate 170 by bolts, rivets, or other fasteners, or by plug-in connections.

[0106] In this embodiment, the fixed plate 170 is fixedly connected to the upright plate 101, which can improve the positional stability of the first driving device 130 and the guide rail assembly 110 on the fixed plate 170, thereby improving the movement stability and positional accuracy of the moving plate 120, positioning module 140, and vision module 150 before and after movement, and further improving the imaging clarity. Furthermore, the guide rail assembly 110 is spaced apart from the upright plate 101 along its length, which helps reduce the positional interference of the upright plate 101 on the guide rail assembly 110 during installation, improves the installation positional accuracy and ease of installation of the guide rail assembly 110, and further improves the positional accuracy of the moving plate 120, positioning module 140, and vision module 150 before and after movement, thus further improving the imaging clarity.

[0107] When using the burr detection device 100 multiple times, it is usually necessary to perform a spot check on the burr detection device 100 before use to ensure the detection accuracy of the burr detection device 100. However, the available space at the installation location of the conveyor line 200 is usually small, and the corresponding spot check structure can easily interfere with the imaging of the electrode 201.

[0108] In some implementations, refer to Figure 3 and Figure 5 The burr detection equipment 100 also includes an inspection photograph 181 and a second driving device 182. The second driving device 182 is fixedly connected to the moving plate 120. The inspection photograph 181 is drivenly connected to the second driving device 182. The second driving device 182 is configured to move the inspection photograph 181. The direction of movement of the inspection photograph 181 forms an angle with the optical axis direction of the image acquisition end of the vision module 150. The processing module is electrically connected to the second driving device 182 to drive the second driving device 182.

[0109] The inspection object 181 can be understood as an object that can be imaged by the vision module 150. The vision module 150 outputs detection data for the inspection object 181, and then compares this data with pre-existing detection data for the inspection object 181 to confirm the detection accuracy of the vision module 150. For example, the inspection object 181 may include a film. The inspection object 181 is connected to the second drive device 182 via a transmission structure, such as a rod, to move the inspection object. For example, the second drive device 182 may be a cylinder or a motor, and it can move the inspection object 181 via an output rod or output shaft. The moving direction of the object being inspected 181 forms an angle with the optical axis of the image acquisition end of the vision module 150. For example, the moving direction of the object being inspected 181 can be perpendicular to the optical axis of the image acquisition end of the vision module 150. For example, the moving direction of the object being inspected 181 is along... Figure 5 In the X-axis direction, the optical axis direction of the image acquisition end of the vision module 150 is along the Z-axis direction (perpendicular to the X-axis). Figure 5 (The direction of the image). Of course, the direction of movement of the object being inspected 181 and the optical axis of the image acquisition end of the vision module 150 can also form an angle of 80 degrees, 70 degrees, 60 degrees, etc. In addition, refer to Figure 7 The processing module can drive the second drive device 182 through preset control commands or drive commands input by buttons, etc., so that the inspection and photographing object 181 moves closer to or further away from the optical axis of the image acquisition end of the vision module 150.

[0110] In this embodiment, the second driving device 182 is fixedly connected to the moving plate 120, and the inspection photograph 181 is drivenly connected to the second driving device 182, enabling the inspection photograph 181 to move simultaneously with the vision module 150 on the moving plate 120. This improves the relative positional accuracy between the inspection photograph 181 and the vision module 150, and also improves the repeatability of positional accuracy in multiple inspections. Furthermore, the second driving device 182 is configured to form an angle between the moving direction of the inspection photograph 181 and the optical axis direction of the image acquisition end of the vision module 150. This facilitates the removal of the inspection photograph 181 after inspection, thereby reducing interference between the inspection photograph 181 and the imaging electrode 201 and improving the space utilization of the burr detection device 100 with inspection function.

[0111] In the above embodiment, the end of the fixing plate 170 is directly connected to the upright plate 101. The suspended end of the guide rail assembly 110 still has a certain amount of droop, and the imaging clarity of the vision module 150 needs to be further improved.

[0112] In some implementations, refer to Figure 5 and Figure 6 The burr detection equipment 100 also includes a stiffening plate 190, with the upright plate 101 and the fixed plate 170 forming angles with the stiffening plate 190 respectively, and the upright plate 101 and the fixed plate 170 being fixedly connected to the stiffening plate 190 respectively.

[0113] The upright plate 101 and the fixed plate 170 form angles with the stiffening plate 190, respectively. For example, the upright plate 101, the fixed plate 170, and the stiffening plate 190 can be perpendicular to each other. Of course, the angle between any two of the upright plate 101, the fixed plate 170, and the stiffening plate 190 can also be set to other angles. The upright plate 101 and the fixed plate 170 can be fixedly connected to the stiffening plate 190 by means of welding, bolts, or other fasteners.

[0114] In this embodiment, the stiffening plates 190, which are fixedly connected to the upright plate 101 and the fixed plate 170 respectively, improve the relative positional accuracy between the fixed plate 170 and the upright plate 101, which is beneficial to improving the positional stability of the guide rail assembly 110 on the fixed plate 170, and to improving the positional accuracy of the moving plate 120, the positioning module 140, and the vision module 150 before and after movement, which is beneficial to further improving the imaging clarity.

[0115] In the above embodiments, in order to avoid motion interference between the stiffener 190 and the moving plate 120, it is usually necessary to make the stiffener 190 avoid the moving plate 120, which results in an increase in the size of the burr detection device 100.

[0116] In some implementations, refer to Figure 2 , Figure 5 and Figure 6 The stiffening rib 190 is provided with an inclined edge 191, which extends from the side of the stiffening rib 190 facing away from the vertical plate 101 to the side of the stiffening rib 190 facing away from the fixed plate 170. For example, the inclined edge 191 extends from... Figure 2 Extending from the left side to the top; see reference Figure 5 At least part of the inclined edge 191 is provided between the fixed plate 170 and the movable plate 120.

[0117] In this embodiment, the rib 190 can improve the utilization rate of the space between the moving plate 120 and the fixed plate 170 by means of the inclined edge 191, reduce the volume of the burr detection device 100, and reduce the risk of motion interference with the moving plate 120 by means of the inclined edge 191.

[0118] In the above embodiments, in order to improve the load-bearing capacity of the fixed plate 170, it is usually necessary to increase the connection strength between the fixed plate 170 and the upright plate 101 by increasing the weld height and increasing the tightening torque of fasteners such as bolts. After improving the connection strength between the fixed plate 170 and the upright plate 101, the position of the fixed plate 170 may change relative to the set position, resulting in a decrease in the positional accuracy of the guide rail assembly 110, the moving plate, the positioning module 140, and the vision module 150, which may lead to a decrease in imaging clarity.

[0119] In some implementations, refer to Figure 5The fixing plate 170 includes a third straight section 171, a second vertical section 172, a fourth straight section 173, and a third vertical section 174 arranged sequentially. The first driving device 130 is fixedly connected to the third straight section 171, and the guide rail assembly 110 is at least partially fixedly connected to the fourth straight section 173. The third straight section 171 and the third vertical section 174 are respectively fixedly connected to the upright plate 101. The second vertical section 172 is fixedly connected to the fourth straight section 173, the second vertical section 172 is detachably connected to the third straight section 171, and a section of the fourth straight section 173 away from the second vertical section 172 is detachably connected to the third vertical section 174.

[0120] The third straight section 171 and the fourth straight section 173 can be understood as the relatively straight parts of the fixing plate 170 at the workstation, and the second vertical section 172 and the third vertical section 174 can be understood as the relatively vertical parts of the fixing plate 170 at the workstation. The first drive device 130 can be fixedly connected to the third straight section 171 by means of fastener connection or snap-fit. The guide rail assembly 110 is at least partially fixedly connected to the fourth straight section 173, including the entire guide rail assembly 110 being fixedly connected to the fourth straight section 173, and the guide rail assembly 110 being partially fixedly connected to the fourth straight section 173. For example, the second guide rail 112 is fixedly connected to the fourth straight section 173 as part of the guide rail assembly 110, specifically by means of fasteners such as bolts, snap-fit, etc. The third straight section 171 and the third vertical section 174 can be fixedly connected to the vertical plate 101 by means of welding, riveting, etc. The second vertical section 172 and the third straight section 171 can be connected by fasteners such as bolts and screws to achieve a detachable connection. The fourth straight section 173, which is away from the second vertical section 172, can be connected by fasteners such as bolts and screws to achieve a detachable connection with the third vertical section 174.

[0121] In this embodiment, the third straight section 171 and the third vertical section 174 can be fixedly connected to the upright plate 101 respectively. Then, the deformation of the third straight section 171 and the third vertical section 174 after connection can be detected. This makes it easier to modify the third straight section 171 and the third vertical section 174 according to their deformation, thereby improving the positional accuracy of the second vertical section 172 and the fourth straight section 173 installed on the third straight section 171 and the third vertical section 174. This is beneficial to improving the positional accuracy of the guide rail assembly 110, the moving plate, the positioning module 140, and the vision module 150, and also to improving the imaging clarity.

[0122] In the case where the guide rail assembly 110 includes a first guide rail 111 and a second guide rail 112, the support stability of the first guide rail 111 and the second guide rail 112 needs to be improved.

[0123] In some implementations, refer to Figure 5 The second vertical section 172 has a fifth straight section 175 on the side facing the moving plate 120, and the fifth straight section 175 is fixedly connected to the second vertical section 172; the first guide rail 111 is fixedly connected to the fifth straight section 175, and the second guide rail 112 is fixedly connected to the fourth straight section 173.

[0124] The fifth straight section 175 can be understood as the relatively straight part of the fixed plate 170 at the work station. The fifth straight section 175 can be fixedly connected to the second vertical section 172 by welding, snap-fitting, fastener connection and other methods.

[0125] In this embodiment, the fifth straight section 175 and the fourth straight section 173 can provide a larger support area for the first guide rail 111 and the second guide rail 112, respectively, which is beneficial to improving the support stability of the first guide rail 111 and the second guide rail 112, thereby improving the positional accuracy of the visual module 150 on the first guide rail 111 and the second guide rail 112 before and after movement, and improving the imaging clarity.

[0126] In the above embodiment, the fixed plate 170 bears a large load, and there is a risk of failure in the connection structure between the fixed plate 170 and the upright plate 101.

[0127] In some implementations, refer to Figure 5 Along the direction toward the moving plate 120, for example, along the upward direction in the figure, at least two of the third straight segment 171, the fourth straight segment 173 and the fifth straight segment 175 are spaced apart, for example, the third straight segment 171, the fourth straight segment 173 and the fifth straight segment 175 are spaced apart sequentially along the direction toward the moving plate 120.

[0128] In this embodiment, after the third straight section 171, the fourth straight section 173, and the fifth straight section 175 are connected by the second vertical section 172 and the third vertical section 174 respectively, the fixing plate 170 as a whole can form a misaligned and tortuous shape, which is beneficial to improving the connection strength with the vertical plate 101 and to improving the service life of the burr detection equipment 100 under the condition of repeated reciprocating movement of components such as the vision module 150.

[0129] In the above embodiments, since the overall weight of the components such as the vision module 150 that the first driving device 130 needs to drive is large, the volume of the first driving device 130 is usually also large, which results in the large volume of the burr detection device 100.

[0130] In some embodiments, based on the fact that the distance from the first straight section 121 to the telecentric lens 153 is less than the distance from the second straight section 123 to the telecentric lens 153, the third straight section 171, the fourth straight section 173 and the fifth straight section 175 are arranged sequentially along the direction toward the moving plate 120, and the first driving device 130 is arranged between the first straight section 121 and the third straight section 171.

[0131] This can be understood as follows: since the distance from the first straight segment 121 to the telecentric lens 153 is relatively small, the distance from the first straight segment 121 to the third straight segment 171 is relatively large; in addition, along the direction toward the moving plate 120, at least two of the third straight segment 171, the fourth straight segment 173, and the fifth straight segment 175 are spaced apart, so the third straight segment 171 is also relatively farther away from the first straight segment 121. Therefore, the space between the first straight segment 121 and the third straight segment 171 is relatively large.

[0132] In this embodiment, the first driving device 130 is disposed between the first straight section 121 and the third straight section 171, which improves the utilization rate of the space between the first straight section 121 and the third straight section 171 and helps to reduce the size of the burr detection device 100.

[0133] In the above embodiments, it is necessary to further reduce the space occupied by the stiffening plate 190 and the second vertical section 172.

[0134] In some implementations, refer to Figure 5 The connection between the aforementioned stiffening plate 190 and the second vertical section 172 includes the stiffening plate 190 and the second vertical section 172 being integrally formed, and the stiffening plate 190 and the second vertical section 172 being fixed by welding, snap-fitting, or other methods.

[0135] In this embodiment, the stiffening plate 190 is connected to the second vertical section 172. Compared with the stiffening plate 190 and the second vertical section 172 being set separately, it is beneficial to reduce the overall space occupied by the stiffening plate 190 and the second vertical section 172, and to reduce the volume of the burr detection equipment 100.

[0136] In the above embodiment, when the moving plate 120 is driven by the first driving device 130, it is necessary to further improve the smoothness of the movement of the moving plate 120.

[0137] In some implementations, refer to Figure 5 A transition block 125 is provided on the side of the first straight section 121 facing the third straight section 171, and the transition block 125 is connected to the output shaft of the first drive device 130.

[0138] The output shaft of the first drive device 130 and the adapter block 125 can be driven by a screw and nut structure.

[0139] In this embodiment, the adapter block 125 is disposed on the side of the first straight section 121 facing the third straight section 171. This is beneficial for reducing the length of the output shaft that is connected to the adapter block 125, reducing dimensional errors such as parallelism error between the output shaft of the first drive device 130 and the moving plate 120 and other structures, enabling the moving plate 120 and its components such as the vision module 150 to move more smoothly, and improving the efficiency of the burr detection equipment 100.

[0140] When processing information, processing modules usually need to balance processing efficiency and processing accuracy. For the same processing module, under the same processing time, processing efficiency and processing accuracy are usually inversely related. For example, when processing accuracy needs to be improved, processing efficiency decreases.

[0141] In some implementations, refer to Figure 4 and Figure 5 The positioning module 140 and the vision module 150 are spaced apart in the conveying direction of the conveying line 200, which is configured to convey the electrode 201 from the positioning module 140 to the vision module 150. It can be understood that the same part of the electrode 201 passes through the positioning module 140 first and then through the vision module 150.

[0142] In this embodiment, the transmission line 200 is configured to transport the electrode 201 from the positioning module 140 to the vision module 150. This allows more processing time for the processing module to process the position information of the edge of the electrode 201, and improves the driving accuracy of the processing module in driving the first driving device 130 according to the current position of the edge of the electrode 201.

[0143] If the conveyor line 200 is configured to include a conveyor belt, the conveyor belt may easily block the detection signal of the positioning module 140 and the light signal of the vision module 150. In order to avoid the obstruction of the conveyor belt, there are more restrictions on the placement of the positioning module 140 and the vision module 150, which may lead to an increase in the overall space occupied by the burr detection equipment 100.

[0144] In some embodiments, the gap between the first roller 210 and the second roller 220 is disposed opposite to the positioning module 140, and the gap between the second roller 220 and the third roller 230 is disposed opposite to the vision module 150.

[0145] This can be understood as the detection signal of the positioning module 140 being able to pass through the gap between the first roller 210 and the second roller 220 and the light signal of the vision module 150 being able to pass through the gap between the second roller 220 and the third roller 230.

[0146] In this embodiment, the positioning module 140 can obtain the current position of the edge of the electrode 201 by the interval between the first roller 210 and the second roller 220, and the vision module 150 can obtain an image of the edge of the electrode 201 by the interval between the second roller 220 and the third roller 230. This improves the utilization rate of the internal space of the conveyor line 200 by the positioning module 140 and the vision module 150, which is beneficial to improving the structural compactness of the burr detection equipment 100.

[0147] When the conveyor line 200 includes multiple rollers such as the first roller 210, the second roller 220, and the third roller 230, it is necessary to further reduce the overall space occupied by the burr detection equipment 100.

[0148] In some implementations, refer to Figure 4 A first arrangement direction is formed between the first roller 210 and the second roller 220, and a second arrangement direction is formed between the second roller 220 and the third roller 230. The angle between the first arrangement direction and the second arrangement direction is greater than 0 degrees.

[0149] The angle between the first and second arrangement directions is greater than 0 degrees, which can be understood as the first and second arrangement directions not being parallel. Therefore, the electrode 201 can advance somewhat tortuously on the first roller 210, the second roller 220, and the third roller 230; for example... Figure 4 The first arrangement direction formed between the first roller 210 and the second roller 220 is generally along the X-axis direction, and the second arrangement direction formed between the second roller 220 and the third roller 230 is generally along the Z-axis direction.

[0150] In this embodiment, a longer electrode 201 can be accommodated between the first roller 210, the second roller 220 and the third roller 230, which improves the buffering capacity of the conveyor line 200 for the electrode 201 and improves the structural compactness of the burr detection device 100.

[0151] In some implementations, refer to Figure 4 and Figure 5 The positioning module 140, the light source assembly 151, and the imaging assembly 152 are arranged sequentially. The moving plate 120 passes through the gap between the second roller 220 and the third roller 230. The positioning module 140 is located on the side of the second roller 220 facing the first roller 210, and at least part of the imaging assembly 152 is located on the side of the second roller 220 facing away from the first roller 210. For example, Figure 5 The positioning module 140 is located on the left side of the second roller 220, and at least part of the shooting component 152 is located on the right side of the second roller 220.

[0152] In this embodiment, the movable plate 120 passes through the gap between the second roller 220 and the third roller 230, thereby further improving the utilization rate of the internal space of the conveyor line 200 and improving the structural compactness of the burr detection device 100. Furthermore, the burr detection device 100 can shield the positioning module 140 or the imaging component 152 by using the conveying electrode 201, reducing the positioning interference of falling burrs and other foreign objects on the positioning module 140 or reducing the imaging interference on the imaging component 152.

[0153] Furthermore, referring to Figure 5 The positioning module 140 can be configured to include a signal transmitting part 141, a connecting part 142, and a signal receiving part 143 connected in sequence. The connecting part 142 is connected to the moving plate 120. The connecting part 142 passes through the gap between the first roller 210 and the second roller 220. The signal transmitting part 141 and the signal receiving part 143 are spaced apart, and the gap between the signal transmitting part 141 and the signal receiving part 143 is configured to allow the electrode 201 to pass through.

[0154] The positioning module 140 can be configured as a photoelectric sensor, ultrasonic sensor, etc., thus possessing the aforementioned signal transmitting part 141 and signal receiving part 143, thereby achieving higher positioning speed and higher positioning accuracy compared to image recognition methods. Furthermore, the connecting part 142 can be understood as the part that connects the signal transmitting part 141 and the signal receiving part 143. The connecting part 142 can be connected to the moving plate 120 via fasteners such as bolts, snap-fit ​​connections, etc.

[0155] In this embodiment, the positioning module 140 can quickly obtain the current position of the edge of the electrode 201 by receiving the signal emitted by the signal transmitting section 141 through the signal receiving section 143. Furthermore, the connecting section 142 passes between the first roller 210 and the second roller 220, and the gap between the signal transmitting section 141 and the signal receiving section 143 is configured to allow the electrode 201 to pass through. This connection section 142 further improves the utilization rate of the internal space of the conveyor line 200, which is beneficial to further improving the structural compactness of the burr detection device 100. In addition, the burr detection device 100 can block the signal transmitting section 141 or the signal receiving section 143 by the conveying electrode 201, reducing the positioning interference of falling burrs and other foreign objects on the positioning module 140.

[0156] In some embodiments, the connecting portion 142 of the positioning module 140 is disposed between the abutting portion of the conveyor line 200 and the upright plate 101. The two ends of the connecting portion 142 are respectively connected to the signal transmitting portion 141. The signal transmitting portion 141, the connecting portion 142 and the signal receiving portion 143 surround to form an opening structure 144. The opening structure 144 is disposed on the side of the connecting portion 142 facing away from the upright plate 101, and the opening structure 144 is configured to allow the electrode 201 to pass through.

[0157] For example, refer to Figure 2 The opening structure 144 formed by the signal transmitting part 141, the connecting part 142 and the signal receiving part 143 is C-shaped in general.

[0158] In this embodiment, the opening structure 144 formed by the signal transmitting part 141, the connecting part 142 and the signal receiving part 143 is provided on the side of the connecting part 142 facing away from the upright plate 101, so that the electrode 201 can pass through the gap between the signal transmitting part 141 and the signal receiving part 143 more quickly through the opening structure 144, thereby improving the ease of use of the burr detection device 100.

[0159] Furthermore, this application also proposes a burr detection method; wherein, the burr detection method can be applied to the aforementioned burr detection equipment 100; see reference Figure 8 The burr detection method includes the following steps: Step S100: Transmit the slit electrode sheet 201; specifically, the slit electrode sheet 201 can be transmitted via the aforementioned transmission line 200.

[0160] Step S200: Obtain the current position of the edge of the electrode 201; specifically, the current position of the edge of the electrode 201 can be obtained through the positioning module 140 described above.

[0161] Step S300: Adjust the focal length by adjusting the distance between the vision module 150 and the edge of the current electrode 201 according to the current position of the edge of the electrode 201. This can be understood as moving the vision module 150 parallel to the width direction of the electrode 201. Specifically, the processing module can determine the offset of the electrode 201 in the width direction during transmission according to the current position of the edge of the electrode 201, and then move the vision module 150 parallel to the width direction of the electrode 201 by driving the first driving device 130.

[0162] Step S400: Take a picture of the edge of the electrode 201 along the width direction of the electrode 201 to obtain an image, which can be understood as obtaining an image of the edge of the electrode 201 through the vision module 150; Step S400: Identify burrs based on the image of the edge of the electrode 201. Specifically, burr identification can be performed using the processing module described above.

[0163] The burr detection method in this application, when in use, can determine the offset of the transmitting electrode 201 in the width direction by obtaining the current position of the edge of the electrode 201. Thus, it can adjust the distance between the vision module 150 and the current edge of the electrode 201 according to the offset of the electrode 201, thereby adjusting the focal length. This can be understood as making the vision module 150 move according to the offset of the electrode 201, which helps to reduce the risk of the edge of the electrode 201 falling out of the depth of field of the vision module 150, reduces the risk of blurred imaging of the vision module 150, and improves the success rate of burr detection.

[0164] In some implementations, refer to Figure 7 and Figure 8 The step of adjusting the focal length by adjusting the distance between the visual module 150 and the edge of the current electrode 201 based on the current position of the edge of the electrode 201 (step S300 above) includes: Step S310: Obtain the current position and the offset of the pre-stored position of the edge of the electrode 201; for example, the offset of the edge of the electrode 201 detected by the positioning module 140 can be expressed as ∆x=x_actual-x_set, where ∆x is the offset, x_actual is the current position (i.e., actual position) of the edge of the electrode 201, and x_set is the pre-stored position (i.e., the set position).

[0165] Step S320: Based on the offset, the movement amount of the vision module 150 along the width direction of the electrode 201 is obtained; in some embodiments, some sub-processing modules of the processing module can be integrated into the positioning module 140. After detecting the offset of the edge of the electrode 201, the offset can be converted into an electrical signal V_signal = k∙∆x; where V_signal is the output electrical signal, and k is the sensitivity coefficient of the positioning module 140. After receiving the electrical signal, the processing module can amplify and calibrate it, thereby outputting a control signal V_control = G∙V_signal, where V_control is the control signal output by the processing module (corresponding to the movement amount of the vision module 150 parallel to the width direction of the electrode 201), and G is the gain of the processing module. In this process, the offset of the electrode 201 will not change abruptly during transmission, and the positioning module 140 is close to the vision module 150 in the transmission direction. Therefore, the offset obtained by the positioning module 140 can be equal to the offset of the vision module 150, thereby reducing the computational load, simplifying the corresponding processing system, and improving system stability.

[0166] In step S330, the focal length is adjusted by adjusting the distance between the vision module 150 and the edge of the current electrode 201 based on the amount of movement. For example, the first drive device 130 then adjusts the positions of the positioning module 140 and the vision module 150 according to the aforementioned control signal V_control.

[0167] In this embodiment, the burr detection method can improve the driving efficiency of moving the vision module 150 by obtaining the position offset of the edge of the electrode 201 and the movement of the vision module 150 parallel to the width direction of the electrode 201, thereby improving the overall execution efficiency of the burr detection method.

[0168] Reference Figures 1 to 7In one embodiment, the burr detection equipment includes a conveyor line 200.

The conveyor line 200 is configured to convey the slit electrode sheets 201. The moving plate 120 is slidably connected to the guide rail assembly 110 and is configured to move along the extension direction of the guide rail assembly 110. The first drive device 130 is driveably connected to the moving plate 120. 130 is configured to move the movable plate 120; a positioning module 140 is disposed on the movable plate 120 and is configured to acquire the current position of the edge of the electrode 201; a vision module 150 is disposed on the movable plate 120 and is configured to acquire an image of the edge of the electrode 201; a processing module is electrically connected to the positioning module 140, the first driving device 130, and the vision module 150 respectively; the processing module is configured to drive the first driving device 130 according to the current position of the edge of the electrode 201, and the processing module is also configured to identify burrs according to the image of the edge of the electrode 201.

The light source assembly 151 and the imaging assembly 152 are respectively disposed between the abutment portion of the conveyor line 200 and the upright plate 101. The light source assembly 151 is configured to emit light in a direction away from the imaging assembly 152. The light source assembly 151 includes a ring light source, the angle between the axis of the ring light source and the width direction of the conveyor line 200 is less than 90 degrees, and the ring light source is configured to emit light in a direction away from the imaging assembly 152.
