Description

Technical Field

[0001] This utility model relates to the field of strip inspection equipment, and in particular to a strip surface defect inspection equipment. Background Technology

[0002] According to the patent document with announcement number CN222913468U, the patent document describes a process where one end of a strip placed on a machine passes through a first conveying space, a second conveying space, a third conveying space, and a fourth conveying space in sequence before being connected to an external take-up roller. A drive motor drives the pinch roller and the fourth guide roller to rotate synchronously, thereby driving the strip transmission. During the strip transmission process, the first and second limit modules guide and limit the movement direction of the strip. The strip passes under the detection probe and the laser. The detection probe detects and identifies defects on the surface of the strip and then transmits the location of the defects to the defect identification machine in the form of an electrical signal. The defect identification machine controls the laser marking machine to mark the defects on the surface of the strip. After the detection is completed, the entire strip is wound onto the take-up roller.

[0003] The patent document states that when the detection probe detects and identifies defects on the surface of the conveyed strip, the air in the production environment may contain a large amount of dust and dust generated during workshop processing. These impurity particles will naturally settle and adhere to the surface of the strip, thereby obscuring the defects on the surface of the strip. This causes the detection probe to be unable to accurately identify the defects, reducing the accuracy of the detection. Utility Model Content

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] like Figures 1-8 As shown, a strip surface defect detection device includes a detection mechanism 1 and a cleaning mechanism 2, which is located on top of the detection mechanism 1.

[0029] In this embodiment: the cleaning mechanism 2 includes a collection cover 201, a cleaning roller 202 rotatably connected to the bottom of the collection cover 201, a motor 203 fixedly installed at the input end of the cleaning roller 202, a collection box 205 provided at the rear side of the collection cover 201, a conveying pipe 204 fixed between the collection box 205 and the collection cover 201, a filter plate 206 fixed inside the collection box 205, a fan 207 fixed at the bottom of the filter plate 206, the collection cover 201 has a trapezoidal cross section, the collection cover 201 is fixed to the top of the machine tool 101, the collection cover 201 is located between the second rotating roller 103 and the support frame 104, and the collection box 205 is fixed to the rear of the machine tool 101. On the side, the conveying pipe 204 consists of three feed pipes and one discharge pipe. The three feed pipes are fixed at equal intervals on the top of the collecting hood 201, and the discharge pipe is fixed to the top of the collecting box 205. The three feed pipes are fixed in front of the discharge pipe. Before the strip passes the detection probe 105, the surface impurity particles are cleaned. The cleaning roller 202 is driven by the motor 203 to rotate, thereby sweeping up the impurity particles on the surface of the strip. During this process, the impurity particles are sucked into the collecting hood 201 by the fan 207 and enter the collecting box 205 through the conveying pipe 204. The impurity particles in the air are intercepted in the collecting box 205 by the filter plate 206 for collection.

[0030] In this embodiment: the detection mechanism 1 includes a machine tool 101, with a plurality of first rollers 102 rotatably connected to the top of the machine tool 101, and a second roller 103 rotatably connected to one side of the top of the machine tool 101. The first rollers 102 are located below the second rollers 103. A support frame 104 is fixed to the top of the machine tool 101, and three detection probes 105 are fixed to the top of the support frame 104. A plurality of defect identification machines 106 are fixed to the other side of the support frame 104. By passing the strip material through the bottom of the second rollers 103 and then through the top of the plurality of first rollers 102, the production line traction device drives the strip material to move continuously from one side to the other side. During this process, the detection probes 105 take pictures of the defects on the surface of the strip material, and the pictures are sent to the defect identification machines 106. Then the defect identification machines 106 judge the defects and issue an alarm. The operator handles the strip material that has been alarmed.

[0031] Working principle: The strip passes through the bottom of the second roller 103 and then through the top of several first rollers 102. The production line traction device drives the strip to move continuously from one side to the other. Before passing the detection probe 105, the strip passes through the cleaning roller 202. The motor 203 drives the cleaning roller 202 to rotate, thereby sweeping up the impurity particles on the surface of the strip. During this process, the fan 207 sucks the impurity particles into the collection hood 201 and into the collection box 205 through the conveying pipe 204. The filter plate 206 intercepts the impurity particles in the air and collects them in the collection box 205. After cleaning, the strip passes through the detection probe 105, which takes pictures of the defects on the surface of the strip. The pictures are sent to the defect identification machine 106, which then judges the defects and alarms. The operator handles the strip that has been alarmed.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
