Description

Technical Field

[0001] The utility model belongs to the technical field of floor film detection, and particularly relates to a PVC floor film surface defect detection device. Background Art

[0002] PVC floor film is a professional protective film, mainly used to protect the surface of floor, tile, marble, etc. This protective film has many characteristics and advantages, such as wear resistance, high light transmittance and second adhesion. PVC floor film is very easy to produce defective products in production. The main causes of defective products are cracks, wear, bubbles, blistering, unevenness, etc. In the production process, PVC floor film needs to be inspected for defects, especially blistering defects. The current inspection method mainly uses a high-brightness LED linear spotlight cold light source to illuminate the film surface, and uses a linear array camera detection instrument for real-time synchronous scanning. The collected image data is used for defect identification and processing through professional image processing software.

[0003] A Chinese patent with publication number CN218726725U discloses a thin film defect detection device, comprising a base; a detection platform is fixedly connected to the top surface of the base; two pairs of symmetrically distributed support rods are fixedly connected to the top surface of the base; a pair of support rods are rotatably connected to a reel through a rotating shaft; a support frame is fixedly connected to the top surface of the detection platform; the support frame is in an inverted U shape; a sliding groove is provided at the bottom of the lateral end of the support frame; the sliding groove is in a T shape; a pair of sliding blocks are slidably connected in the sliding groove; the sliding block is in a T shape; and a lighting lamp is provided at the bottom of the sliding block.

[0004] Through the above technical solution, it can be understood that when inspecting a film with a relatively small width, in order to reduce energy consumption and reduce the number of lighting sources used on the device, the lighting source needs to be adjusted. When adjusting, the lighting source needs to slide through the sliding block at the upper end in the sliding groove of the support frame, and then the fixed structure on the sliding block is clamped in the fixed groove on one side of the sliding groove to fix it, which makes the adjustment and use more cumbersome and inconvenient.
