[0013] In the above technical solution, preferably, one end of the connecting rope is fixedly connected to the surface of the winding rod, and the other end of the connecting rope passes through the connecting tube and is fixedly connected to the surface of the supporting bar.

[0014] In the above technical solution, preferably, two symmetrically distributed clamps are provided on the top of the support platform, and a slide plate is fixedly connected to the bottom of the two clamps.

During the movement of the first detection component, the connecting tube is driven to slide along the inner wall of the center hole of the profile, so that the connecting tube can be inspected together with the first detection component, thereby reducing blind spots in detection, improving detection accuracy, and enabling better defect detection at various locations of the profile.

[0018] When a defect occurs inside the center hole of the profile and the connecting tube cannot pass through normally, the motor is started to drive the winding rod to reel in the connecting rope. In the process, the connecting rope can be used to drive the support bar close to the connecting tube, so that the support bar does not contact the inner wall of the center hole, thereby enabling the profile to be erected and the second detection component to be taken out.

DETAILED DESCRIPTION

[0028] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] like Figure 1-Figure 8 The industrial profile defect detection device based on computer vision shown includes a workbench 1, a support frame 101 is fixedly connected to the top of the workbench 1, an industrial computer 2 is arranged on one side of the workbench 1, a uniformly distributed support table 4 is fixedly connected to the top of the workbench 1, and a detection structure 3 is arranged on the inner side of the support frame 101;

[0031] The detection structure 3 includes a first detection component 31 disposed inside the support frame 101, and a second detection component 32 is disposed below the first detection component 31;

[0032] Among them, the first detection component 31 includes a linear slide rail 3101 arranged on the top of the support frame 101, the bottom of the linear slide rail 3101 is fixedly connected to an electric push rod 3102, the bottom of the electric push rod 3102 is fixedly connected to a mounting plate 3103, the bottom of the mounting plate 3103 is fixedly connected to an evenly distributed connecting shell 3104, the interior of the connecting shell 3104 is provided with a first LED lamp 3106, and the bottom of the mounting plate 3103 is provided with two first industrial cameras 3105 that are symmetrically distributed.

[0033] The industrial profile to be inspected is placed on the support table 4, and the mounting plate 3103 is driven to move to the opening height of the internal groove of the profile by starting the electric push rod 3102. The mounting plate 3103 is driven to move synchronously by starting the linear slide rail 3101 through the electric push rod 3102, so that it can move into the internal groove of the profile. In this process, the surface of the profile can be supplemented with light by starting the first LED light 3106, so that the first industrial camera 3105 can better detect the surface of the profile and transmit the image information to the industrial computer 2 for the staff to check and compare.

[0034] like Figure 1-Figure 8 As shown, a mounting rod 3111 is fixedly connected to the bottom of the mounting plate 3103 , a connecting block 3108 is fixedly connected to the bottom of the mounting rod 3111 , and an electromagnet 3109 is embedded and installed at the bottom of the connecting block 3108 .

[0035] The top of the connecting block 3108 is fixedly connected to two symmetrically distributed supporting blocks 3107 , the top of the supporting block 3107 is fixedly connected to a reflector 3110 , and the top of the connecting block 3108 is provided with two symmetrically distributed second industrial cameras 3112 .

[0036] Specific visible Figure 7 , where the dotted line represents the normal of the reflector 3110, and the line marked with an arrow is the light path formed by one group of first LED lights 3106 after being reflected by the reflector 3110. It can be seen that the blind spots of the internal groove of the profile can be supplemented with light, so that the second industrial camera 3112 can shoot the blind spots of the internal groove of the profile, thereby avoiding the poor shooting effect at the blind spots in the traditional profile inspection process.

[0037] like Figure 1-Figure 8 As shown, the second detection component 32 includes a connecting tube 3201, one side of which is fixedly connected to a mounting block 3205, the surface of the mounting block 3205 is embedded with evenly distributed third industrial cameras 3213, and the surface of the mounting block 3205 is embedded with evenly distributed second LED lights 3214.

[0038] The surface of the connecting tube 3201 is provided with three support bars 3206 distributed in a ring shape, a groove is provided on the side of the support bar 3206 away from the connecting tube 3201, evenly distributed balls 3208 are provided inside the groove, an adsorption block 3210 is embedded and installed at the center of the inner bottom wall of the groove, the adsorption block 3210 is an iron material component, and two symmetrically distributed adjustment rods 3211 are fixedly connected to the other side of the support bar 3206.

[0039] Three groups of sliding cavities 3204 are provided inside the connecting tube 3201 . The other end of the adjusting rod 3211 is slidably connected to the inner wall of the sliding cavity 3204 . A spring 3203 is fixedly connected between the adjusting rod 3211 and the inner wall of the sliding cavity 3204 .

[0040] By pressing the support bar 3206, the adjustment rod 3211 can be driven to retract into the sliding cavity 3204. In this process, the spring 3203 can be squeezed so that the support bar 3206 can be close to the connecting tube 3201, thereby reducing the volume of the overall structure. At this time, the support bar 3206 and the connecting tube 3201 can be placed in the center hole of the profile. Loosening the support bar 3206 can drive the adjustment rod 3211 to reset under the action of the spring 3203, so that the support bar 3206 is close to the inner wall of the center hole of the profile, and the connecting tube 3201 is pushed to slide along the inner wall of the center hole. The setting of the ball 3208 is used to reduce the friction force during the movement of the connecting tube 3201. In this process, the second LED lamp 3214 can be used to fill the inner wall of the center hole of the profile with light, so that the third industrial camera 3213 can detect the inside of the center hole.

[0041] During the movement of the first detection component 31, the electromagnet 3109 is energized, and the electromagnet 3109 can generate magnetic force, thereby generating suction on the adsorption block 3210, and driving the connecting tube 3201 to slide along the inner wall of the center hole of the profile during the movement of the first detection component 31, so that the profile can be inspected together with the first detection component 31, thereby reducing blind spots in detection, improving detection accuracy, and enabling better defect detection of various parts of the profile.

[0042] like Figure 1-Figure 8 As shown, a motor 3202 is disposed inside the connecting tube 3201 , and an output shaft of the motor 3202 is fixedly connected to a winding rod 3209 . Three storage chambers 3207 are provided inside the connecting tube 3201 , and a connecting rope 3212 is disposed inside the storage chamber 3207 .

[0043] One end of the connecting rope 3212 is fixedly connected to the surface of the winding rod 3209 , and the other end of the connecting rope 3212 passes through the connecting tube 3201 and is fixedly connected to the surface of the supporting bar 3206 .

[0044] When a defect occurs inside the center hole of the profile and the connecting tube 3201 cannot pass through normally, the motor 3202 is started to drive the winding rod 3209 to wind up the connecting rope 3212. In the process, the connecting rope 3212 can drive the support bar 3206 to approach the connecting tube 3201, so that the support bar 3206 does not contact the inner wall of the center hole, so that the profile can be erected to take out the second detection component 32.

[0045] like Figure 1-Figure 8As shown, two symmetrically distributed clamps 401 are provided on the top of the support platform 4, and the bottoms of the two clamps 401 are fixedly connected with slide plates 402, and the slide plates 402 are slidably connected to the inner walls of the adjacent support platforms 4. One of the support platforms 4 is internally rotatably connected with a bidirectional screw rod 403, and the slide plate 402 is threadedly connected to the surface of the bidirectional screw rod 403, and one end of the bidirectional screw rod 403 passes through the support platform 4 and is fixedly connected with a rotating wheel.

[0046] The rotating wheel can drive the bidirectional screw rod 403 to rotate, thereby driving the two slide plates 402 to approach each other, and then the two clamping plates 401 can approach each other to clamp the profile, so as to facilitate the detection of the profile.

[0047] Working principle: Place the industrial profile to be inspected on the support table 4, start the electric push rod 3102 to drive the mounting plate 3103 to the opening height of the internal groove of the profile, and start the linear slide rail 3101 to drive the mounting plate 3103 to move synchronously through the electric push rod 3102, so that it can move into the internal groove of the profile, and at the same time put the second detection component 32 into the center hole of the profile, and start the electromagnet 3109. In this process, the first LED light 3106 can be started to fill the surface of the profile with light, so that the first industrial camera 3105 can better detect the surface of the profile and transmit the image information to the industrial computer 2 for inspection and comparison by the staff. In this process, the first LED light 3106 The light path formed after the light is reflected by the reflector 3110 can fill in the blind spots of the internal groove of the profile, so that the second industrial camera 3112 can shoot the blind spots of the internal groove of the profile, avoiding the poor shooting effect at the blind spots in the traditional profile inspection process. During the movement of the first inspection component 31, the electromagnet 3109 is energized. At this time, the electromagnet 3109 can generate magnetic force, which can generate suction to the adsorption block 3210, and drive the connecting tube 3201 to slide along the inner wall of the center hole of the profile during the movement of the first inspection component 31, so that it can inspect the profile together with the first inspection component 31, reducing the detection blind spots, improving the detection accuracy, and better able to detect defects in various parts of the profile.
