[0032] The drawings of the present invention are only used for illustrative purposes and cannot be construed as limiting the present invention. In order to better illustrate the following embodiments, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0033] Example 1

[0034] like Figures 1 to 5 As shown, this embodiment discloses a material strip detection device, including a feeding mechanism, a receiving mechanism, a first driving assembly 11, a second driving assembly 22 and a visual detection mechanism.

[0035] The feeding mechanism is used to install the material belt, and the receiving mechanism is used to receive the material belt from the feeding mechanism. The first driving component 11 is installed on the frame 10 and connected to the feeding mechanism, and is used to drive the feeding mechanism to release the material belt; the second driving component 22 is installed on the frame 10 and connected to the receiving mechanism, and is used to drive the receiving mechanism to reel the material belt from the feeding mechanism. The visual inspection mechanism is installed on the frame 10 and is arranged between the feeding mechanism and the receiving mechanism, and is used to detect whether the load on the material belt is abnormal.

[0036] The material belt detection device of this embodiment drives the feeding mechanism to release the material belt through the first driving component 11, and drives the retracting mechanism to reel in the material belt released by the feeding mechanism through the second driving component 22, thereby realizing automatic reeling of the material belt. The visual detection mechanism detects the load on the material belt, thereby realizing the function of automatically detecting the load on the material belt, improving the accuracy and reliability of the detection of the load on the material belt, and significantly reducing the possibility of false detection and missed detection.

[0037] In this embodiment, the feeding mechanism includes a feeding tray 12 and a tension adjustment component movably mounted on the frame 10, wherein the tension adjustment component is disposed on a side of the feeding tray 12 close to the visual inspection mechanism and is used to adjust the tension of the material strip during the winding process. The feeding tray 12 is connected to the first driving component 11, and the first driving component 11 is used to drive the feeding tray 12 to rotate and release the material strip.

[0038] like Figure 2As shown, the tension adjustment assembly includes a pressure wheel 13 and a roller 14 that are movably mounted on the frame 10 and are arranged opposite to each other. The roller 14 is provided with a groove 141 that matches the material strip. A clamping station is formed between the pressure wheel 13 and the roller 14 so that the material strip is held in the clamping station for winding. The roller 14 is used to support and guide the material strip, and the pressure wheel 13 is used to provide tension for the material strip so that the material strip will not be deformed when passing through the station formed by the pressure wheel 13 and the roller 14 during the winding process. The pressure wheel 13 can be specifically implemented by a tensioning wheel. By using a tensioning wheel to tension the material strip, the tension of the material strip during the winding process can be more flexibly controlled.

[0039] In some embodiments, the material receiving structure includes a material receiving tray 21, and the material receiving tray 21 is connected to the output end of the second drive assembly 22. In the specific implementation process, the second drive assembly 22 can be driven by a motor or other driver, and the material receiving tray 21 is connected to the output end of the second drive assembly 22 so that the second drive assembly 22 drives the material receiving tray 21 to rotate and then rewind the material tape.

[0040] like Figure 3 As shown, specifically, the visual inspection mechanism includes a camera 32 mounted on the frame 10. The camera 32 is arranged perpendicular to the winding path of the material belt, and is used to photograph the load on the material belt. In the specific implementation process, the camera 32 can be arranged just above the winding path of the material belt, so that the viewing angle of the camera 32 can completely cover the load on the material belt, thereby accurately collecting the image information of the material belt, which is convenient for subsequent identification.

[0041] In some optional embodiments, the visual inspection mechanism further includes an illumination device (not shown in the figure), which is used to provide light for the camera 32. Adding an illumination device can provide stable and sufficient light for the camera 32, so that the material strip inspection device of this embodiment is suitable for low-light environments.

[0042] There are two visual inspection mechanisms, which are arranged along the extension direction of the material belt from the feeding mechanism to the receiving mechanism. By arranging two visual inspection mechanisms one in front and one behind, the possibility of missed inspection and false inspection can be reduced to a greater extent, and the accuracy and reliability of the material belt inspection device can be improved.

[0043] In some optional embodiments, the material strip detection device also includes a clamping device 4 arranged between the feeding mechanism and the receiving mechanism. Preferably, the clamping device 4 is arranged between the tension adjustment assembly and the receiving mechanism. The clamping device 4 is used to guide the material strip to be wound from the feeding mechanism to the receiving mechanism to prevent the material strip from deviating during the winding process.

[0044] Specifically, Figure 4As shown, the material strip clamping device 4 includes a mounting bracket 40, and the mounting bracket 40 is provided with a third driving component 41 and a fourth driving component 42, the third driving component 41 is connected to a first clamping member 43, and the fourth driving component 42 is connected to a second clamping member 44, and the first clamping member 43 and the second clamping member 44 are parallel and relatively arranged; the third driving component 41 and the fourth driving component 42 respectively drive the first clamping member 43 and the second clamping member 44 to move vertically up and down, and the first clamping member 43 and the second clamping member 44 are arranged at a distance so that the first clamping member 43 and the second clamping member 44 clamp the material strip when they are relatively close.

[0045] The material tape detection device of this embodiment further includes an optical fiber sensor 5, which is arranged on the winding path of the material tape and is used to monitor the number of carriers on the material tape to facilitate counting the number of components that have completed detection.

[0046] In this embodiment, the objects carried by the material tape may be various components, such as crystal oscillators, chips or other components. The material tape detection device of this embodiment can conveniently detect whether the components in the material tape are abnormal.

[0047] In specific application, the material belt is pre-installed on the feed tray 12 and part of the material belt is released, and the released end of the material belt is installed on the receiving tray 21, and then the material belt between the feed tray 12 and the receiving tray 21 is placed on the groove 141 of the roller 14 in the tension adjustment component, and the material belt is clamped on the clamping station formed by the roller 14 and the pressure wheel 13, and the first clamping member 43 and the second clamping member 44 of the clamping device clamp the material belt. When working, the material belt detection device is started, the first drive component 11 drives the feed tray 12 of the feed mechanism to rotate and release the material belt, and the second drive component 22 drives the receiving tray of the receiving mechanism to rotate and rewind the material belt. When the material belt is reeled from the feed tray 12 to the receiving tray 21, the camera 32 will collect the image information of the material belt in real time, and send the collected image information to the subsequent processor for recognition and processing. During the material strip inspection process, the lighting device can be turned on according to the light conditions of the working environment. When the light is too dark, the lighting device can be turned on to provide sufficient light for the camera 32, so that the camera 32 can collect clear material strip image information. In addition, during the inspection process, the camera 32 will adjust the parameters of the camera 32 according to the light conditions of the environment so that the camera 32 can collect clearer images.
