[0009] Optionally, the upper clamping plate assembly further includes a guide unit, which is mounted on the support frame, and the light-transmitting pressure plate is mounted on the guide unit. The guide unit is used to guide the movement of the light-transmitting pressure plate.
[0010] Optionally, the upper vision mechanism includes an upper vision camera and an upper supplementary lighting component. Both the upper vision camera and the upper supplementary lighting component are mounted on the support frame. The upper vision camera is used to identify the coating position on the upper surface of the material, and the upper supplementary lighting component is used to provide supplementary lighting for the upper vision camera.
[0011] The lower vision mechanism includes a lower vision camera and a lower supplementary lighting component. Both the lower vision camera and the lower supplementary lighting component are mounted on the support frame. The lower vision camera is used to identify the coating position on the lower surface of the material, and the lower supplementary lighting component is used to supplement the lower vision camera with light.
[0012] Optionally, the upper supplementary lighting assembly includes an upper supplementary lighting plate and an upper supplementary lighting lamp. The upper supplementary lighting plate is mounted on the support frame and has a through hole. The upper vision camera is mounted on the support frame and is located on the side of the upper supplementary lighting plate away from the clamping mechanism. The upper vision camera can pass through the through hole to identify the coating position on the upper surface of the material. The upper supplementary lighting lamp is mounted on the side of the upper supplementary lighting plate away from the upper vision camera.
[0013] The lower supplemental lighting assembly includes a lower supplemental lighting plate and a lower supplemental lighting lamp. The lower supplemental lighting plate is mounted on the support frame and has a through hole.

[0017] On the other hand, this utility model embodiment provides an electrode die-cutting device, including the double-sided misalignment detection device as described above.
[0018] This utility model provides a double-sided misalignment detection device and electrode die-cutting equipment, which, compared with the prior art, have at least the following advantages: When double-sided coating position detection of materials is required, the conveying mechanism first conveys the material to be detected to the clamping mechanism where it can hold the material to be detected. Then, the clamping mechanism clamps the material to be detected from both the top and bottom. Finally, the upper vision mechanism identifies the coating position on the upper surface of the material through the clamping mechanism, and the lower vision mechanism identifies the coating position on the lower surface of the material at the same position through the clamping mechanism. By comparing the coating position on the upper surface of the material identified by the upper vision mechanism with the coating position on the lower surface of the material identified by the lower vision mechanism, the misalignment between the coating positions on the upper and lower surfaces of the material is determined. Because the clamping mechanism can hold the material to be detected from both the top and bottom when using this double-sided misalignment detection device to perform double-sided coating position detection, material wrinkles are avoided, thereby improving the accuracy of double-sided coating position detection.

[0026] like Figure 1 As shown, an embodiment of the present invention provides a double-sided misalignment detection device 100, which includes a conveying mechanism 110, a clamping mechanism 120, an upper vision mechanism 130, and a lower vision mechanism 140. The conveying mechanism 110 is used to convey the material to be detected. The clamping mechanism 120 can clamp the material to be detected from the upper and lower sides. The upper vision mechanism 130 can identify the coating position on the upper surface of the material through the clamping mechanism 120. The lower vision mechanism 140 can identify the coating position on the lower surface of the material at the same position through the clamping mechanism 120.
[0027] When double-sided coating position detection of materials is required, the conveying mechanism 110 first conveys the material to be detected to the clamping mechanism 120, which can clamp the part to be detected. Then, the clamping mechanism 120 clamps the material to be detected from the upper and lower sides. Finally, the upper vision mechanism 130 identifies the coating position on the upper surface of the material through the clamping mechanism 120, and the lower vision mechanism 140 identifies the coating position on the lower surface of the material at the same position through the clamping mechanism 120. By comparing the coating position on the upper surface of the material identified by the upper vision mechanism 130 with the coating position on the lower surface of the material identified by the lower vision mechanism 140, the misalignment between the coating position on the upper surface and the coating position on the lower surface of the material is determined.
[0028] In the existing double-sided misalignment detection device 100, when detecting the position of the double-sided coating of a material, the material to be tested is supported and placed on a support platform. The wrinkled parts of the material to be tested are misaligned in the vertical direction, which causes the coating on the upper and lower surfaces of the material to be misaligned in the horizontal direction, affecting the accuracy of the position of the double-sided coating of the material being detected.
[0029] When using the double-sided misalignment detection device 100 provided in an embodiment of this utility model to detect the double-sided coating position of materials, the clamping mechanism 120 can clamp the material to be detected from both the upper and lower sides, so that the upper and lower surfaces of the material to be detected are at the same height, avoiding the influence of material wrinkles on the detection results, thereby improving the accuracy of double-sided coating position detection.
[0030] One embodiment of this utility model provides a double-sided misalignment detection device 100, such as... Figure 1 As shown, the clamping mechanism 120 includes an upper clamping plate assembly 121 and a lower clamping plate assembly 122. The upper clamping plate assembly 121 can clamp materials from the top, and the lower clamping plate assembly 122 can clamp materials from the bottom.
[0031] When double-sided coating position detection of materials is required, the conveying mechanism 110 first conveys the material to be detected to the clamping mechanism 120, which can clamp the part to be detected. Then, the upper clamping assembly 121 clamps the material from the top, and the lower clamping assembly 122 clamps the material from the bottom. The upper clamping assembly 121 and the lower clamping assembly 122 work together to attach and press the material, so that the material is flattened. Finally, the upper vision mechanism 130 identifies the coating position on the upper surface of the material through the clamping mechanism 120, and the lower vision mechanism 140 identifies the coating position on the lower surface of the material at the same position through the clamping mechanism 120. By comparing the coating position on the upper surface of the material identified by the upper vision mechanism 130 with the coating position on the lower surface of the material identified by the lower vision mechanism 140, the misalignment between the coating positions on the upper and lower surfaces of the material is determined.
[0032] In this embodiment, the lower clamping plate assembly 122 includes a support frame and a light-transmitting platform, with the light-transmitting platform mounted on the support frame. The upper clamping plate assembly 121 includes a clamping drive unit and a light-transmitting pressure plate, with the clamping drive unit mounted on the support frame. The clamping drive unit can drive the light-transmitting pressure plate to cooperate with the light-transmitting platform to clamp the material.
[0033] When double-sided coating position detection of materials is required, the conveying mechanism 110 first conveys the material to be detected to the clamping mechanism 120, which can clamp the part to be detected. Then, the clamping drive unit drives the light-transmitting pressure plate to approach the light-transmitting platform, so that the light-transmitting pressure plate and the light-transmitting platform cooperate to clamp the material. The light-transmitting pressure plate and the light-transmitting platform cooperate to attach and press the material tightly, so that the material is flattened. Finally, the upper vision mechanism 130 identifies the coating position on the upper surface of the material through the clamping mechanism 120, and the lower vision mechanism 140 identifies the coating position on the lower surface of the material at the same position through the clamping mechanism 120. By comparing the coating position on the upper surface of the material identified by the upper vision mechanism 130 with the coating position on the lower surface of the material identified by the lower vision mechanism 140, the misalignment between the coating positions on the upper and lower surfaces of the material is determined.
[0034] In one specific embodiment, the light-transmitting platform is bolted to the support frame. The clamping drive unit is a drive cylinder, and the light-transmitting pressure plate is installed at the output end of the drive cylinder. The drive cylinder can drive the light-transmitting pressure plate to move vertically, so that the light-transmitting pressure plate moves closer to or away from the light-transmitting platform. Both the light-transmitting platform and the light-transmitting pressure plate are made of optical glass, which has excellent light transmittance, making it easy for the vision mechanism to identify the coating position on the surface of the material through the light-transmitting platform or the light-transmitting pressure plate.
[0035] Of course, it is understandable that the light-transmitting platform can also be fixedly installed on the support frame in other ways, such as riveting, or the light-transmitting platform can be installed on the support frame and then the support frame can be welded to the support frame; this is not limited here. The clamping drive unit can also use other components, such as drive cylinders, linear motors, etc., with the light-transmitting pressure plate installed at the output end of the drive cylinder, linear motor, etc.; this is not limited here. The light-transmitting platform and the light-transmitting pressure plate can also be made of other light-transmitting materials, such as plexiglass; this is not limited here.
[0036] In another embodiment, the lower clamping plate assembly 122 includes a support frame, a translation drive unit, and a light-transmitting platform. The translation drive unit is mounted on the support frame, and the light-transmitting platform is mounted on the output end of the translation drive unit. The translation drive unit can drive the light-transmitting platform to move closer to or away from the light-transmitting pressure plate. The upper clamping plate assembly 121 includes a clamping drive unit and a light-transmitting pressure plate. The clamping drive unit is mounted on the support frame, and the clamping drive unit can drive the light-transmitting pressure plate to cooperate with the light-transmitting platform to clamp the material.
[0037] When it is necessary to clamp the material to be inspected, the translation drive unit drives the light-transmitting platform to approach the light-transmitting pressure plate, and at the same time the clamping drive unit drives the light-transmitting pressure plate to approach the light-transmitting platform, so that the light-transmitting pressure plate and the light-transmitting platform cooperate to clamp the material.
[0038] The double-sided misalignment detection device 100 provided in one embodiment of this utility model includes an upper clamping plate assembly 121 that further includes a guide unit. The guide unit is mounted on a support frame, and a light-transmitting pressure plate is mounted on the guide unit. The guide unit guides the movement of the light-transmitting pressure plate in a vertical direction. When the clamping drive unit drives the light-transmitting pressure plate closer to or further away from the light-transmitting platform, the guide unit can guide the movement of the light-transmitting pressure plate to ensure the consistency of the movement direction of the light-transmitting pressure plate, so that the light-transmitting pressure plate always moves in a vertical direction.
[0039] In one specific embodiment, the guiding unit is selected as a guide rail. In this embodiment, the guiding unit includes two guide rails spaced apart in the horizontal direction, and a groove is provided on the light-transmitting pressure plate, which slides in cooperation with the guide rail. Of course, it can be understood that the guiding unit can also be a guide groove, with the light-transmitting pressure plate having a rail and the groove sliding in cooperation with the guide rail. The guiding unit can also be a guide rod, etc., which is not limited here.
[0040] The present invention provides a double-sided misalignment detection device 100, comprising an upper vision mechanism 130 including an upper vision camera and an upper supplementary lighting component, both mounted on a support frame. The upper vision camera is used to identify the coating position on the upper surface of the material, and the upper supplementary lighting component is used to supplement the light on the upper vision camera. The lower vision mechanism 140 includes a lower vision camera and a lower supplementary lighting component, both mounted on a support frame. The lower vision camera is used to identify the coating position on the lower surface of the material, and the lower supplementary lighting component is used to supplement the light on the lower vision camera.
[0041] The upper supplemental lighting component illuminates the upper vision camera, improving the clarity of the image recognized by the upper vision camera; the lower supplemental lighting component illuminates the lower vision camera, improving the clarity of the image recognized by the lower vision camera. Other vision components can also be used for the vision camera, such as 2D cameras, 3D cameras, etc., without limitation.
[0042] In this embodiment, the upper supplementary lighting assembly includes an upper supplementary lighting plate and an upper supplementary lighting lamp. The upper supplementary lighting plate is mounted on a support frame and has a through hole. The upper vision camera is mounted on the support frame and is located on the side of the upper supplementary lighting plate away from the clamping mechanism 120. The upper vision camera can pass through the through hole to identify the coating position on the upper surface of the material. The upper supplementary lighting lamp is mounted on the side of the upper supplementary lighting plate away from the upper vision camera.
[0043] The lower supplementary lighting assembly includes a lower supplementary lighting plate and a lower supplementary lighting lamp. The lower supplementary lighting plate is mounted on a support frame and has through holes. A lower vision camera is mounted on the support frame and is located on the side of the lower supplementary lighting plate away from the clamping mechanism 120. The lower vision camera can pass through the through holes to identify the coating position on the lower surface of the material. The lower supplementary lighting lamp is mounted on the side of the lower supplementary lighting plate away from the lower vision camera.
[0044] When the upper vision mechanism 130 identifies the coating position on the upper surface of the material through the clamping mechanism 120, and the lower vision mechanism 140 identifies the coating position on the lower surface of the material at the same position through the clamping mechanism 120, the upper vision camera passes through the through hole to identify the coating position on the upper surface of the material; the lower vision camera passes through the through hole to identify the coating position on the lower surface of the material.
[0045] The upper fill light is mounted around the outer edge of the upper fill light plate on the side opposite to the upper vision camera; the lower fill light is mounted around the outer edge of the lower fill light plate on the side opposite to the lower vision camera. Because the through hole is located in the middle of the fill light plate and the fill lights are mounted around one outer edge of the fill light plate, the outer periphery of the vision camera can be illuminated to ensure that the light intensity around the vision camera is uniform.
[0046] In one specific embodiment, the supplementary light is an LED light, and the supplementary light plate is a square mounting plate, with the LED light mounted on one outer edge of the supplementary light plate. Of course, it is understood that other supplementary light components, such as incandescent lamps, can also be used, and this is not limited here.
[0047] One embodiment of this utility model provides a double-sided misalignment detection device 100, such as... Figure 1 As shown, the conveying mechanism 110 includes two conveying rollers 111, which are located on both sides of the clamping mechanism 120 in the horizontal direction.
[0048] When double-sided coating position detection of materials is required, firstly, two conveying rollers 111 rotate to transport the material to be detected to the clamping mechanism 120, which can clamp the part to be detected. Then, the clamping drive unit drives the light-transmitting pressure plate to approach the light-transmitting platform, so that the light-transmitting pressure plate and the light-transmitting platform cooperate to clamp the material. The light-transmitting pressure plate and the light-transmitting platform cooperate to attach and press the material tightly, so that the material is flattened. Finally, the upper vision mechanism 130 identifies the coating position on the upper surface of the material through the clamping mechanism 120, and the lower vision mechanism 140 identifies the coating position on the lower surface of the material at the same position through the clamping mechanism 120. By comparing the coating position on the upper surface of the material identified by the upper vision mechanism 130 with the coating position on the lower surface of the material identified by the lower vision mechanism 140, the misalignment between the coating position on the upper surface of the material and the coating position on the lower surface of the material is determined.
[0049] In addition, such as Figure 1 As shown, another embodiment of this utility model provides an electrode die-cutting device, which includes a double-sided misalignment detection device 100 as provided in any of the above embodiments. The specific structure of the double-sided misalignment detection device 100 is the same as described in the above embodiments. Since this electrode die-cutting device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
[0050] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
