[0026] Example 1

[0027] like Figure 1 As shown, this embodiment provides a material belt abnormality detection device, including a workbench 1, an image acquisition device, a controller, a labeling mechanism 5 and a conveying assembly. The workbench 1 is used to carry a material belt, and the material belt carries parts that need to be detected for abnormality. The image acquisition device is used to acquire images of the parts on the material belt on the workbench 1; the controller is connected to the image acquisition device, and is used to detect abnormal parts according to the image data acquired by the image acquisition device; the labeling mechanism 5 is connected to the controller, and the image acquisition device and the labeling mechanism 5 are arranged in sequence along the extension direction of the workbench 1, and the labeling mechanism 5 is used to label the material belt position corresponding to the abnormal part detected by the controller; the conveying assembly is used to convey the material belt in the workbench 1 from the direction of the image acquisition device to the direction of the labeling mechanism 5.

[0028] Specifically, the conveying assembly includes a material discharging assembly and a material receiving assembly, the material discharging assembly is arranged before the image acquisition device, and the material receiving assembly is arranged after the labeling mechanism 5, that is, the image acquisition device is arranged between the material discharging assembly and the material receiving assembly.

[0029] like Figure 1 As shown, the material discharge assembly includes a material discharge turntable 21 and a material discharge drive structure 22 connected to the material discharge turntable 21 , and the material collection assembly includes a material collection turntable 31 and a material collection drive structure 32 connected to the material collection turntable 31 .

[0030] In some optional embodiments, the unloading drive structure 22 includes an unloading motor, the output end of which is connected to the unloading turntable 21, and the unloading turntable 21 is driven to rotate by the unloading motor to release the material belt on the unloading turntable 21. Similarly, the retracting drive structure 32 includes a retracting motor 321, the output end of which is connected to the retracting turntable 31, and the unloading turntable 31 is driven to rotate by the retracting motor. Through the coordination of the unloading motor and the retracting motor, the material belt released by the unloading turntable 21 is reeled into the retracting turntable 31 when the parts on the material belt are inspected.

[0031] The material belt detection device of this embodiment also includes a lifting assembly 33, and the material receiving assembly is slidably connected to the lifting assembly 33, and the lifting assembly 33 is used to drive the material receiving assembly to move up and down. In specific implementation, a vertical slide rail 331 can be set on the lifting assembly 33, and a matching slider 332 is slidably connected to the slide rail 331. The material receiving drive structure 32 also includes a material receiving mounting member 322, and the material receiving motor 321 is installed on the material receiving mounting member 322 and its motor shaft passes through the material receiving mounting member 322 and is connected to the material receiving turntable 31. The material receiving mounting member 322 is fixed on the slider 332, and the height of the material receiving assembly is controlled by adjusting the position of the slider 332 on the slide rail 331 up and down.

[0032] like Figure 1 In the present embodiment, the image acquisition device includes a camera 42, which is connected to the controller (not shown in the figure). The camera 42 is vertically arranged on the conveying path of the material belt on the workbench, and is used to capture the image of the parts of the material belt. In the specific implementation process, the camera 42 can be arranged just above the winding path of the material belt, so that the viewing angle of the camera 42 can completely cover the parts on the material belt, thereby accurately acquiring the image information of the material belt, which is convenient for subsequent identification.

[0033] like Figure 1As shown, in order to improve the accuracy of detection, multiple image acquisition devices can be set, and multiple image acquisition devices are arranged along the extension direction of the material belt from the unloading component to the receiving component, preferably two. By setting two image acquisition devices, one in front and one in the back, the probability of mismatching and missing parts on the material belt can be further reduced, and the reliability of abnormal part detection on the material belt can be improved.

[0034] like Figure 4 As shown, in this embodiment, the labeling mechanism 5 includes a label stripping component 50 and a labeling component. The label stripping component 50 is provided with a label tape 53. The label stripping component 50 is used to strip the label 54 on the label tape 53, and the labeling component is used to stick the label 54 stripped by the label stripping component on the abnormal part on the workbench 1.

[0035] The label stripping component 50 can use a label stripping machine to strip the label from the label tape. The labeling component is provided with a suction nozzle 51 and a driver 52. The suction nozzle 51 is connected to the output end of the driver 52, and the suction nozzle 51 is driven by the driver 52 to move up and down and forward and backward. When in use, the suction nozzle 51 absorbs the stripped label 54 with the cooperation of the driver 52, and then moves to the top of the material tape corresponding to the abnormal part and sticks the label on the abnormal part of the corresponding material tape.

[0036] The material strip abnormality detection device further includes a clamping assembly 6, which is used to guide the material strip to be wound from the unwinding assembly to the winding assembly to prevent the material strip from deviating during the winding process.

[0037] like Figure 3 As shown, the clamping assembly 6 includes a mounting bracket 61, and the mounting bracket 61 is provided with a first driver 62 and a second driver 63. The first driver 62 is connected to a first clamping arm 620, and the second driver 63 is connected to a second clamping arm 630. The first clamping arm 620 and the second clamping arm 630 are arranged parallel to each other. The first driver 62 and the second driver 63 drive the first clamping arm 620 and the second clamping arm 630 to move vertically up and down respectively. The first clamping arm 620 and the second clamping arm 630 are arranged at a distance so that the first clamping arm 620 and the second clamping arm 630 are close to each other to form a clamping station to clamp the material strip.

[0038] The material belt abnormality detection device of this embodiment also includes at least two counting sensors 7, which are arranged above the workbench. Among them, at least one counting sensor 7 is located before the image acquisition device, and is used to monitor the number of parts on the material belt passing through the counting sensor 7; at least one counting sensor 7 is located after the labeling mechanism, and is used to monitor the number of abnormal parts in the material belt. In the specific implementation process, the counting sensor 7 can use an optical fiber sensor to realize counting, and the optical fiber sensor is arranged just above the material belt in the workbench to monitor the number of parts that have completed the inspection and the number of abnormal parts.

[0039] like Figure 5 As shown, the workbench 1 is also provided with a slide 11 matching the material belt, and a detachable cover plate 12 is provided above the slide 11. The cover plate 12 is provided with through holes 13 at positions corresponding to the image acquisition device, the counting sensor and the labeling component. During operation, as the material belt is rolled up, the image acquisition device can collect images of the parts on the material belt one by one through the corresponding through holes 13. At the same time, the counting sensor 7 can accurately sense the labeled parts on the material belt through the through holes 13 at the corresponding positions, thereby realizing the counting function of abnormal parts.

[0040] In this embodiment, the parts carried by the material tape may be but are not limited to various components, such as crystal oscillators, chips, etc.

[0041] When in use, the material tape to be tested is pre-installed on the unloading turntable 21, and part of the material tape is released so that the released end of the material tape is correctly installed on the reeling turntable 31. At the same time, the label tape 53 is pre-placed at the designated position of the label stripping component 50. During operation, the first drive component 22 drives the unloading turntable 21 to rotate so as to release the material tape; at the same time, the second drive component 32 drives the reeling turntable 31 to rotate to receive the material tape transferred from the unloading turntable 21. Under the cooperation of the first drive component 22 and the second drive component 32, the material tape is gradually reeled from the unloading turntable 21 to the reeling turntable 31. During the winding process, the material strip enters the chute 11 on the workbench, and then passes through the counting sensor 7 before the image acquisition device. The counting sensor 7 monitors the number of parts passing through the through hole 13 of the cover plate 12 at its corresponding position, and then the material strip passes through the image acquisition device. At this time, the camera 42 captures the image data of the parts on the material strip through the through hole 13 at its corresponding position and transmits it to the controller. The controller detects whether the parts are abnormal. If the corresponding parts are abnormal, the winding operation is suspended when the corresponding parts reach the middle of the through hole 13 of the cover plate 12 corresponding to the labeling component. At this time, the label stripping component 50 strips the label 54, and the suction nozzle 51 absorbs the label and moves to the position of the through hole 13 of the corresponding cover plate 12 to attach the label 54 to the corresponding abnormal part. After labeling is completed, the suction nozzle 51 resets to the initial position, and the material strip continues to be wound until all the material strips on the unwinding turntable 21 are wound onto the receiving turntable 31 and the detection is completed.
