Description

Technical Field

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

[0002] With the vigorous development of my country's manufacturing industry, the requirements for the surface quality of products are becoming more and more stringent, and relevant tests need to be carried out on the surface of products, such as flatness test, scratch test, crack test, etc. Among them, the aluminum profile frame is a frame structure made of aluminum alloy material. It uses aluminum alloy profiles as the main structural material and assembles aluminum alloy profiles through connectors to form a frame structure. The aluminum profile frame has the characteristics of light weight, high strength, corrosion resistance, and easy processing.

[0003] Existing surface defect detection devices are generally only able to detect one side of the aluminum profile frame, such as the profile surface defect detection device for aluminum profile production provided by Chinese patent CN202110470863.5, which includes a profile conveying mechanism and a dial indicator gauge and other structures. The dial indicator gauge is arranged above the profile conveying mechanism. The profile conveying mechanism can support and convey the aluminum profile to the detection position, and then the surface defects of the aluminum profile at the detection station are detected by the dial indicator gauge. The profile surface defect detection device in this patent does not have a structure that can automatically flip the aluminum profile. When it is necessary to detect the other surface of the aluminum profile, it is necessary to manually flip the aluminum profile frame, which increases the workload. After long-term manual work, the efficiency is not easy to guarantee, which affects the efficiency of the detection. Utility Model Content

The detection mechanism 4 is arranged above the supporting mechanism 2, and the detection mechanism 4 can perform defect detection on the upper surface of the part to be detected before and after flipping.

[0037] The surface defect detection device 100 provided by the utility model first places the workpiece to be detected on the first carrier plate 201 and the second carrier plate 202, and uses the detection mechanism 4 to complete the detection of the surface to be detected before flipping; then the third driving mechanism 303 drives the clamping mechanism 301 to move toward the flipping space 5, and the clamping mechanism 301 clamps the workpiece to be detected to prevent the workpiece to be detected from falling off during the flipping process; the first driving mechanism 203 drives the first carrier plate 201 and the second carrier plate 202 to move along the first straight line and away from each other, so that the distance between the first carrier plate 201 and the second carrier plate 202 can meet the flipping requirements of the workpiece to be detected, that is, enough flipping space 5 is left to avoid interference with the flipping mechanism 3 or the workpiece to be detected during the flipping process; The clamping mechanism 301 is driven to rotate around the second straight line by the third driving mechanism 303 to realize the in-situ flipping of the to-be-detected piece; after the flipping is completed, the first driving mechanism 203 drives the first carrier plate 201 and the second carrier plate 202 to move along the first straight line and close to each other, so that the distance between the first carrier plate 201 and the second carrier plate 202 is reduced and moved below the to-be-detected piece; the clamping mechanism 301 releases the to-be-detected piece, and the to-be-detected piece is supported by the first carrier plate 201 and the second carrier plate 202, and the clamping mechanism 301 is driven by the second driving mechanism 302 to move in a direction away from the flipping space 5 until it does not block the detection mechanism 4; the detection of the to-be-detected surface after flipping is completed by the detection mechanism 4, thereby completing the double-sided detection of a to-be-detected piece.

[0038] In this embodiment, the support mechanism 2 further includes a first stopper 204 and a second stopper 205. The first stopper 204 and the second stopper 205 are fixedly connected to the support surfaces of the first carrier plate 201 and the second carrier plate 202, respectively. The part to be detected is used to be arranged between the first stopper 204 and the second stopper 205.

Before placing the part to be detected, the first carrier 201 and the second carrier 202 are driven to approach or move away from each other by the first driving mechanism 203, so that the distance between the first limiting surface 206 and the third limiting surface 208 matches the size of the part to be detected along the first straight line direction. When the part to be detected is placed between the two limiting surfaces, the first limiting surface 206 and the third limiting surface 208 can respectively contact the two corresponding surfaces of the part to be detected, thereby limiting the movement of the part to be detected along the first straight line; by placing the part to be detected in contact with both the second limiting surface 207 and the fourth limiting surface 209, the second limiting surface 207 and the fourth limiting surface 209 can limit the part to be detected from continuing to move in the direction close to the flipping mechanism 3, thereby limiting the movement of the part to be detected in the direction close to the flipping mechanism 3.

When the first driving mechanism 203 drives the active rod 212 to move in a direction close to the supporting mechanism 2, under the restriction of the first connecting rod 215 and the second connecting rod 216, the first connecting member 213 and the second connecting member 214 move in a direction close to each other, and apply forces to the first carrier plate 201 and the second carrier plate 202 through the first driven rod 217 and the second driven rod 218 respectively, so that the first carrier plate 201 and the second carrier plate 202 move in a direction close to each other; similarly, when the first driving mechanism 203 drives the active rod 212 to move in a direction away from the supporting mechanism 2, under the restriction of the first connecting rod 215 and the second connecting rod 216, the first connecting member 213 and the second connecting member 214 move in a direction away from each other, and apply forces to the first carrier plate 201 and the second carrier plate 202 through the first driven rod 217 and the second driven rod 218 respectively, so that the first carrier plate 201 and the second carrier plate 202 move in a direction away from each other.

The end of the second clamping member 309 away from the support mechanism 2 can extend into the guide groove 312 through the opening, and the end of the second clamping member 309 away from the support mechanism 2 can be slidably connected to the guide groove 312. Preferably, the third connecting member 311 is fixedly connected to the receiving plate 306. The inner side wall and the inner bottom wall of the guide groove 312 can contact the outer walls corresponding to the first clamping member 308 and the second clamping member 309 to guide and limit the first clamping member 308 and the second clamping member 309, prevent the first clamping member 308 and the second clamping member 309 from rotating during the movement, and improve the stability of the up and down movement of the first clamping member 308 and the second clamping member 309.

[0048] In this embodiment, the clamping mechanism 301 further includes at least one positioning block 313, and at least one positioning block 313 is fixedly connected to the first clamping member 308 and / or the second clamping member 309. The positioning block 313 on the first clamping member 308 protrudes from the surface of the first clamping member 308 on the side close to the second clamping member 309, and the positioning block 313 on the second clamping member 309 protrudes from the surface of the second clamping member 309 on the side close to the first clamping member 308. The positioning block 313 is used to extend into the corresponding positioning groove on the part to be detected and match with the positioning groove on the part to be detected. When the part to be detected needs to be clamped, the positioning block 313 is aligned with the corresponding positioning groove on the part to be detected, and the third driving mechanism 303 drives the first clamping member 308 and the second clamping member 309 to move in a direction close to each other, and the positioning block 313 gradually snaps into the corresponding positioning groove on the part to be detected until the positioning block 313 abuts against the bottom wall of the corresponding positioning groove, so that the two first clamping members 308 and the second clamping member 309 stop moving, and the outer wall of the positioning block 313 is also in contact with the inner wall of the corresponding positioning groove, thereby limiting the movement of the part to be detected compared to the first clamping member 308 and the second clamping member 309, and improving the stability during flipping. In addition, the guiding and limiting effect of the guide groove 312 on the first clamping member 308 and the second clamping member 309 can also ensure that the positioning block 313 can be well snapped into the corresponding positioning groove.

[0049] As a preferred embodiment, it also includes a controller. A pressure detection component such as a pressure sensor can be set on the bottom wall of the positioning groove. The controller is communicated with the pressure detection component. When the pressure detected by the pressure detection component is greater than the preset value of the controller system, the controller controls the fourth drive mechanism 310 to stop driving the two first clamping members 308 and the second clamping member 309, and controls the third drive mechanism 303 to drive the flipping mechanism 3 to flip.

[0050] As a preferred embodiment, a gantry 6 is fixedly connected to the upper surface of the detection frame 1, and a plurality of detection mechanisms 4 are fixedly connected to the side of the gantry 6 close to the detection frame 1. The detection mechanisms 4 and the turning space 5 are arranged opposite to each other up and down.

[0051] As a preferred embodiment, the first driving mechanism 203 is a telescopic mechanism, preferably a cylinder. The third driving mechanism 303, the driving body 304, and the fourth driving mechanism 310 are all motors.
