[0033] The existing manual quality inspection of mobile phone button appearance requires high experience of the quality inspectors. After a long period of time and in large quantities of product inspections, the quality inspectors' attention decreases, the probability of missed inspections and wrong inspections increases, and defective products are often returned, which is not conducive to the development of mobile phone button manufacturers.

[0034] Based on the above technical problems, the present application proposes a mobile phone button appearance defect detection device, wherein the mobile phone button appearance defect detection device has a simple structure, does not involve complicated manufacturing processes and expensive materials, and has high economic efficiency. At the same time, for manufacturers, the mobile phone button appearance defect detection device provided by the present application is easy to produce and low-cost, which is more conducive to controlling production costs and further conducive to product promotion and use.

[0035] Schematic diagram of mobile phone keypad appearance defect detection equipment,

[0036] refer to Figures 1 to 4 According to a preferred embodiment of the present invention, a mobile phone key appearance defect detection device is provided. Figure 1 As shown, it includes a base 10 , a loading module 20 , a visual inspection module 30 , a defective part separation module 40 , a unloading module 50 and a conveying module 60 .

[0037] Specifically, Figure 1As shown, the loading module 20, the visual inspection module 30, the defective part separation module 40, the unloading module 50 and the conveying module 60 are all arranged on the base 10, and the visual inspection module 30 is located between the loading module 20 and the defective part separation module 40, the unloading module 50 is located on the side of the defective part separation module 40 away from the visual inspection module 30, and the conveying module 60 includes two conveying devices 601 and a transfer device 602, the transfer device 602 is located between the visual inspection module 30 and the defective part separation module 40, one of the conveying devices 601 is slidably installed on the base 10 between the loading module 20 and the transfer device 602, and the other conveying device 601 is slidably installed on the base 10 between the transfer device 602 and the unloading module 50.

[0038] It should be noted that a plurality of mobile phone buttons to be inspected are placed on a tray 90 in a rectangular array, and the trays 90 are placed one by one on the loading module 20. The trays 90 on the loading module 20 are transported to the visual inspection module 30 area by a conveying device 601, and the mobile phone buttons to be inspected arranged in a rectangular array on the tray 90 are photographed row by row by the visual inspection module 30, and the images are uploaded, compared and analyzed with the standard images, and defective parts and qualified parts are classified by label. After each of the mobile phone buttons on the tray 90 is inspected, the conveying device 601 is used to transport the mobile phone buttons to the loading module 20. 601 delivers the material tray 90 to the transfer device 602, and then the conveying device 601 moves back to the direction of the loading module 20 and repeats the above action. At the same time, another conveying device 601 moves the material tray 90 placed on the transfer device 602 to the defective part separation module 40, and the mobile phone keys classified as defective parts are unloaded to a separate area through the defective part separation module 40. After each defective part is picked out, the material tray 90 and the qualified products thereon are delivered to the unloading module 50 through the conveying device 601 close to the unloading module 50 to complete the unloading. It is obvious that compared with the manual inspection of appearance in the prior art, the embodiment of the present application has the advantages of high degree of automation, more stable inspection, and applicability to large-scale inspection by setting the loading module 20, the visual inspection module 30, the defective part separation module 40, the unloading module 50 and the conveying module 60.

[0039] Furthermore, if Figure 2 and Figure 3As shown, the loading module 20 includes two first seat bodies 201 and two first clamping cylinders 202. The base 10 has a through groove 101 in the length direction. The two conveying devices 601 slide along the length direction of the through groove 101. The two first seat bodies 201 are respectively located on both sides of the through groove 101. Each of the first seat bodies 201 is provided with a first clamping cylinder 202 in a bolted manner, and the push rods of the two first clamping cylinders 202 are arranged relative to each other.

[0040] It should be noted that, refer to Figures 1 to 3 The material tray 90 is placed between the two first clamping cylinders 202, and the push rods of the two first clamping cylinders 202 respectively abut against the two ends of the material tray 90 to fix the position of the material tray 90 in the height direction. When the conveying device 601 close to the loading module 20 moves to the bottom of the material tray 90 and lifts the bottom wall of the material tray 90, the push rods of the two first clamping cylinders 202 move in opposite directions and are separated from the ends of the material tray 90. Then, the material tray 90 will follow the conveying device 601 to move up and down in the height direction, and move along the through groove 101 in the length direction of the base 10.

[0041] Further, in order to place a plurality of the trays 90 at the same time, as Figure 2 and Figure 3 As shown, the loading module 20 also includes a plurality of first guide plates 203. More specifically, each of the first base bodies 201 is detachably provided with two spaced-apart first guide plates 203, and the first clamping cylinder 202 on each of the first base bodies 201 is located between the two first guide plates 203, and each of the first guide plates 203 is vertically arranged.

[0042] It should be noted that, by setting the first guide plate 203, multiple material trays 90 can be stacked in the height direction, but it should be pointed out that at this time, only the material tray 90 located at the bottom is clamped by the two first clamping cylinders 202, and the remaining material trays 90 are stacked in the height direction of the base 10 by the support of the clamped material trays 90 and the position of the first guide plate 203.

[0043] Furthermore, if Figure 1 As shown, the visual inspection module 30 includes a first linear module 301 and four cameras 302. The four cameras 302 are arranged side by side and are all fixedly mounted on the slider of the first linear module 301 and move with it. The first linear module 301 is vertically arranged with the through groove 101. When the first linear module 301 is working, the slider of the first linear module 301 moves back and forth in the width direction of the base 10.

[0044] It should be noted that in the embodiment of the present application, the sensor model of each camera 302 is IMX264, the resolution is 2448×2048, and the color is black and white. In addition, the lens model on each camera 302 is MVL-MF5028M-8MP. The surface image of the mobile phone buttons to be inspected is collected by the camera 302, which provides a prerequisite for the external appearance defect detection system to compare, analyze and classify the collected image with the preset image. Since the technology of the appearance defect detection system is mature and widely used in the market, the specific structure and model of the appearance defect detection system are not described here. The appearance defect detection system includes but is not limited to the appearance defect detection system disclosed in the patent document (CN117798087A) that can compare, analyze and classify the collected images.

[0045] It should also be noted that, since four cameras 302 are provided, the four cameras 302 can respectively capture images of the four to-be-detected mobile phone buttons on the material tray 90 at the same time. Since the mobile phone buttons are arranged in a rectangular array on the material tray 90, it should be noted that the number of mobile phone buttons in each row is greater than four. Therefore, when detecting the collected buttons in one row, the conveying device 601 close to the loading module 20 is in a stationary state. Since the four cameras 302 are all installed on the slider of the first linear module 301, the four cameras 302 are driven by the first linear module 301 to move horizontally until the images of the mobile phone buttons in this row are all captured. Then, the conveying device 601 close to the loading module 20 moves a predetermined distance toward the defective parts separation module 40, and makes the mobile phone buttons in another row face the four cameras 3 02, repeat the above actions until the image of each mobile phone button on the material tray 90 is captured and processed, and then the material tray 90 is driven to move to the bottom of the transfer device 602 by a conveying device 601 close to the loading module 20, and the material tray 90 is driven to move upward a predetermined distance by this loading module 20, and the material tray 90 is clamped by the transfer device 602 to realize the transfer of the material tray 90, and then, the conveying device 601 close to the loading module 20 moves toward the loading module 20 and moves another material tray 90 and repeats the above actions, while the other conveying device 601 removes the material tray 90 from the transfer device 602 and moves it to the defective parts separation module 40, and after the defective parts are taken out, the material tray 90 supporting the qualified parts is moved to the unloading module 50.

[0046] Furthermore, if Figure 1As shown, the defective part separation module 40 includes a second linear module 401, four suction cups 402 arranged side by side and a defective part disk 403, the defective part disk 403 is slidably set on the base 10, and the defective part disk 403 is located on one side of the through groove 101, the second linear module 401 is arranged parallel to the first linear module 301, and the four suction cups 402 are fixedly installed on the slider of the second linear module 401.

[0047] It should be noted that the suction cup 402 is connected to an external air source. When the material tray 90 moves to the defective parts separation module 40, the defective mobile phone keys on the material tray 90 are adsorbed by the four suction cups 402, and the material tray 90 is driven to move in the width direction of the base 10 by the second linear module 401, and the defective mobile phone keys are moved to the defective parts tray 403 to achieve separation of the defective parts. Similarly, when adsorbing the mobile phone keys in the same row, the conveying device 601 close to the unloading module 50 is in a stationary state. When the defective parts in the mobile phone keys in the same row are all adsorbed and placed on the defective parts tray 403, the conveying device 601 close to the unloading module 50 moves a predetermined distance toward the unloading module 50, and makes the mobile phone keys in another row located directly below the four suction cups 402, and repeats the above actions.

[0048] Furthermore, if Figure 4 As shown, the conveying module 60 further includes two third linear modules 603 arranged at intervals, the third linear modules 603 correspond to the conveying devices 601 one by one, and each of the conveying devices 601 is fixedly connected to a slider of the corresponding third linear module 603 .

[0049] In addition, if Figure 3 and Figure 4 As shown, each of the conveying devices 601 includes a mounting seat 6011, a lifting seat 6012, two second clamping cylinders 6013 and a lifting drive device 6014, the mounting seat 6011 is fixedly connected to the slider of the corresponding third linear module 603, the lifting drive device 6014 is fixedly mounted on the mounting seat 6011, and the push rod of the lifting drive device 6014 is fixedly connected to the lifting seat 6012, and the two second clamping cylinders 6013 are arranged on both sides of the lifting seat 6012 relatively.

[0050] It should be noted that, the mounting seat 6011 is driven to move along the length direction of the base 10 by the third linear module 603, and the lifting seat 6012 is driven to move upward or downward by the lifting drive device 6014. When the bottom of the material tray 90 is lifted by the lifting seat 6012, the two second clamping cylinders 6013 clamp the material tray 90 to prevent the position of the material tray 90 from shifting.

[0051] Furthermore, if Figure 1 As shown, the unloading module 50 includes two second base bodies 501 and two third clamping cylinders 502. The two second base bodies 501 are respectively located on both sides of the through groove 101. Each of the second base bodies 501 is provided with a third clamping cylinder 502, and the push rods of the two third clamping cylinders 502 are arranged relative to each other.

[0052] In addition, if Figure 1 As shown, the unloading module 50 also includes a plurality of second guide plates 503, and each of the second base bodies 501 is detachably provided with two spaced-apart second guide plates 503, and the third clamping cylinder 502 on each of the second base bodies 501 is located between two of the second guide plates 503, and each of the second guide plates 503 is vertically arranged.

[0053] It should be noted that, in the unloading module 50, the tray 90 is gradually moved upward from the bottom and stacked, and in the loading module 20, the tray 90 is gradually sent out from the bottom to the lifting seat 6012 after being stacked. More specifically, after each defective part on a tray 90 is placed on the defective part tray 403, the conveying device 601 close to the conveying module 60 moves toward the unloading module 50 and positions the tray 90 between the second guide plates 503, drives the tray 90 upward by a predetermined distance through the lifting drive device 6014, and causes the two third clamping cylinders 502 to clamp the tray 90.

[0054] In summary, the mobile phone key appearance defect detection device based on the embodiment of the present application is explained, which provides the mobile phone key appearance defect detection device with advantages such as a higher degree of automation, more stable detection, and suitability for large-scale detection.

[0055] It is worth mentioning that in the embodiment of the present application, the mobile phone key appearance defect detection device has a simple structure, does not involve complex manufacturing processes and expensive materials, and has high economic efficiency. At the same time, for manufacturers, the mobile phone key appearance defect detection device provided by the present application is easy to produce and has low cost, which is more conducive to controlling production costs and further conducive to product promotion and use.
