DETAILED DESCRIPTION

[0031] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. The embodiments in the present application and the features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0032] Referring to Figures 1-7 The present application discloses an optical visual surface defect detection device, comprising:

[0033] The side surface square support 1 is composed of a top plate 11 and two lateral support frames 12 arranged at the bottom of the top plate 11.

[0034] At least one material taking module 2 is arranged on the top plate 11, used for taking undetected products from the driven sub-stage and putting the detected products back on the driven sub-stage.

[0035] At least one optical visual detection module 3 is arranged between the two lateral support frames 12, which comprises a camera assembly 31 used for optical visual detection of the material taken by the material taking module 2, a Z-axis moving assembly 32 used for driving the camera assembly 31 to move along the Z-axis direction of the side surface square support 1, a Y-axis moving assembly 33 used for driving the Z-axis moving assembly 32 to move along the Y-axis direction of the side surface square support 1, and an X-axis moving assembly 34 used for driving the Y-axis moving assembly 33 to move along the X-axis direction of the side surface square support 1.

[0036] According to the present application, the Z-axis moving assembly 32, the Y-axis moving assembly 33 and the X-axis moving assembly 34 are arranged to drive the camera assembly 31 to move along three axes, so that when the material taken by the material taking module 2 changes, the distance between the camera assembly 31 and the detected product can be adjusted, the shooting angle and position can meet the normal detection requirements, and the universality of the equipment detection is improved.

[0037] In an embodiment, the material taking module 2 comprises a mounting assembly 21 arranged on the top plate 11, a vertical plate 22 arranged on the mounting assembly 21, a rotating motor 23 arranged on the vertical plate 22 and capable of sliding up and down along the height direction of the vertical plate 22, a lifting assembly 24 arranged on the mounting assembly 21 and used for driving the rotating motor 23 to slide up and down, and a suction disc assembly 25 arranged at the output end of the rotating motor 23 and capable of rotating under the driving of the rotating motor 23.

[0038] In this way, the suction cup assembly 25 can suck the product on the mover platform by lifting movement, and can rotate the product by the rotating motor 23 after sucking the product, so that the optical vision detection module 3 can detect the product in different directions.

[0039] In an embodiment, the mounting assembly 21 comprises a support 211 fixedly connected with the top plate 11, the support 211 is provided with a movable plate 212 capable of sliding along the y-axis direction of the side surface passing through the bracket 1, the vertical plate 22 and the lifting assembly 24 are arranged on the movable plate 212, the support 211 is provided with a threaded groove for screw installation, and the movable plate 212 is provided with a strip-shaped hole for screw sliding.

[0040] In this way, after the screw is loosened, the movable plate 212 can slide along the y-axis direction of the side surface passing through the bracket 1, the suction position of the suction cup assembly 25 is adjusted, and after the adjustment is completed, the movable plate 212 is fixed to the support 211 by the friction force by tightening the screw, so that the position of the suction cup assembly 25 can be adjusted according to the placement position of the product, and more product taking and placing requirements can be adapted.

[0041] In an embodiment, the output end of the rotating motor 23 is provided with a rotating disc 26 capable of rotating synchronously with the suction cup assembly 25, and the rotating motor 23 is further provided with a photoelectric door sensor 27 sleeved outside the rotating disc 26, and the rotating disc 26 is provided with a perforation for the photoelectric door sensor 27 to emit light.

[0042] In this way, when the perforation position of the rotating disc 26 is dislocated from the position of the light emitted by the photoelectric door sensor 27, the photoelectric door sensor 27 can be triggered to emit a signal, so that when the product rotation angle reaches the required angle by adjusting the position of the perforation, the light of the photoelectric door sensor 27 can pass through the perforation on the rotating disc 26, and the change of the signal emitted by the photoelectric door sensor 27 can be used to determine whether the product is rotated to the position, at this time, the rotating motor 23 can be controlled to stop, and the accuracy of subsequent detection is improved.

[0043] In an embodiment, the number of the optical vision detection module 3 is four, and two are arranged in front and back along the conveying direction of the mover platform, and the two optical vision detection modules 3 in the same group are arranged on the two sides of the conveying direction of the mover platform, the number of the taking module 2 is two, and the two taking modules 2 correspond to the two groups of optical vision detection modules 3, and the taking module 2 is located between the two optical vision detection modules 3 in the same group.

[0044] In this way, by dividing the four optical vision detection modules 3 into two groups, each group of optical vision detection modules 3 can simultaneously detect two side surfaces of the product. After one group of optical vision detection modules 3 finishes detection, the product is rotated by 90 degrees, and the other group of optical vision detection modules 3 can be used to detect the other two side surfaces. The two groups of optical vision detection modules 3 can operate simultaneously, effectively improving the product detection efficiency.

[0045] In specific implementation, the four optical vision detection modules 3 are respectively an optical vision detection module for detecting the surface A of the product, an optical vision detection module for detecting the surface B of the product, an optical vision detection module for detecting the surface C of the product, and an optical vision detection module for detecting the surface D of the product. In order to avoid interference between the optical vision detection modules 3 and other equipment, each optical vision detection module 3 can be installed on the top plate 11 or the ground according to requirements.

[0046] In an embodiment, the X-axis moving assembly 34 includes an X-axis guide rail 341 arranged along the X-axis direction of the side square-shaped support 1x and an X-axis sliding table 342 slidingly arranged on the X-axis guide rail 341. An adjusting knob 343 is threadedly arranged on the X-axis sliding table 342 and penetrates the X-axis sliding table 342 and abuts against the X-axis guide rail 341.

[0047] In this way, when the product changes, the operator can loosen the adjusting knob 343 to slide the X-axis sliding table 342, and after the X-axis sliding table 342 is slid to the required position, the operator can tighten the adjusting knob 343 to fix the position of the X-axis sliding table 342. Thus, after the product changes, the camera assembly 31 can move and adjust in the X-axis direction according to requirements.

[0048] In an embodiment, the Y-axis moving assembly 33 includes a Y-axis linear module 331 arranged on the X-axis sliding table 342 and a mounting plate 332 driven by the Y-axis linear module 331 to move along the y-axis direction of the side square-shaped support 1.

[0049] In this way, when the position between the product and the camera assembly 31 does not meet the requirements, the Y-axis linear module 331 can be started to drive the camera assembly 31 to move and adjust in the Y-axis direction. Since the Y-axis linear module 331 does not need to be manually operated, the camera assembly 31 can be timely adjusted after the product is rotated by 90 degrees, so that the camera assembly 31 can correctly capture the rotated product.

[0050] In an embodiment, the Z-axis moving assembly 32 includes a housing 321 arranged on the mounting plate 332, a lead screw 322 rotatably arranged on the housing 321 and inserted into the housing 321, a screw nut 323 arranged on the lead screw 322 and capable of moving up and down along the lead screw 322, and a connecting frame 324 penetrating the housing 321 and connected to the camera assembly 31.

[0051] This design allows the operator to drive the lead screw nut 323 up and down by rotating the lead screw 322 when the product changes, thereby moving the camera assembly 31 on the connecting frame 324 to adjust its movement in the Z-axis direction.

[0052] In one embodiment, at least one fill light for supplemental lighting is detachably provided on the camera assembly 31.

[0053] This design allows the camera assembly 31 to be equipped with one or more supplementary lights as needed to meet the lighting requirements in different environments.

[0054] It should be noted that the aforementioned rotary motor 23, lifting assembly 24, suction cup assembly 25, photoelectric door sensor 27, and camera assembly 31 are common knowledge in the field, therefore their specific structural composition and working principle will not be described in detail in this article.

[0055] It should be noted that if the embodiments of the present invention 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 certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0056] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
