Description

Technical Field

[0001] The utility model belongs to the technical field of detection equipment, and in particular relates to a product surface defect detection equipment. Background Art

In conventional product inspection lines, the product is mainly transported to each inspection station for inspection of various items using fixtures, suction cups or conveyor lines. Therefore, when inspecting surface defects of the product, the product inspection line cannot complete the defect inspection of the entire appearance of the product because the contact area between the fixture, suction cup or conveyor line and the product is blocked. Utility Model Content

[0004] The product surface defect detection equipment includes a machine platform, which is equipped with a conveying device, which drives a clamp. A pre-inspection device is arranged on the side of the conveying device for the clamp to pass through, and the pre-inspection device is used to detect surface defects of specific parts of the product. A manipulator is arranged at the end of the conveying device, and the manipulator drives a suction cup that relays with the clamp and is used to adsorb specific parts of the product. A full inspection device that cooperates with the suction cup is arranged next to the manipulator, and the full inspection device is used to detect surface defects of all parts of the product except the specific parts.

[0005] According to the technical solution, the utility model can achieve the following beneficial effects:

[0006] The clamp grabs the product, and the conveying device drives the clamp with the product to move through the pre-inspection device so that the pre-inspection device can pre-inspect the surface of the specific part of the product. After that, the conveying device drives the clamp with the product to move to the end, and the robot drives the suction cup to move to the specific part of the product and adsorbs the specific part of the product. After that, the robot drives the suction cup with the product to move to the full inspection device, and the full inspection device inspects the surface of all parts except the specific part of the product, thereby realizing a comprehensive inspection of the product appearance.

[0007] In order to further optimize the above technical solution, it can be optionally combined with one or more of the following implementation methods without conflict.

[0008] In some embodiments, a dust removal device for blowing ionized air on the product in advance is provided next to the pre-inspection device; according to the technical solution, before the pre-inspection device and the full inspection device inspect the product surface, ionized air is blown on the product in advance for dust removal, thereby improving the inspection accuracy.

[0009] In some embodiments, the conveying device drives a support plate, and the support plate is equipped with a transverse rotating cylinder that drives the clamp to rotate transversely; according to the technical solution, the conveying device can adjust the inclination angle of the product before or during the process of driving the clamp holding the product to pass through the pre-inspection device, so that the pre-inspection device can detect products with curved surfaces or inclined surfaces. At the same time, by adjusting the bevel angle of the product, it can better relay with the suction cup on the robot.

[0010] In some embodiments, the support plate is also equipped with a longitudinal rotating cylinder that drives the clamp to rotate longitudinally; according to the technical solution, through the setting of the longitudinal rotating cylinder, the product clamped by the clamp can adjust the inclination angle at multiple angles, so that when the conveying device drives the clamp holding the product to move to the end, it can further better relay with the suction cup on the robot.

[0011] In some embodiments, the conveying device includes a transverse screw module, which drives a transverse plate, and the transverse plate is equipped with a lifting screw module that drives the support plate to rise and fall; according to the technical solution, the transverse screw module is set so that the fixture holding the product can move horizontally smoothly, so that the pre-inspection device can stably detect the surface of a specific part of the product, and the lifting screw module can adjust the height of the product after the fixture clamps the product, so that the pre-inspection device can more accurately detect the product.

[0012] In some embodiments, the pre-inspection device includes an arched fill light and a linear array camera that cooperates with the arched fill light; according to the technical solution, the surface inspection of a specific part of the product can be completed by moving the fixture horizontally through the pre-inspection device, thereby improving inspection efficiency.

[0013] In some embodiments, the full inspection device includes a plurality of area array cameras arranged in a surrounding manner and a full inspection fill light cooperating with the area array cameras; according to the technical solution, a large area of ​​the surface of the product adsorbed by the suction cup can be inspected, thereby further improving the inspection efficiency.
