[0035] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0036] like Figure 1 The figure shows the structure diagram of the automatic crack detection device of the utility model, which includes a support component 1, a positioning component 2, a flip component 3 and a detection component 4. The support component 1 is used to support the product to be detected, and the positioning component 2 and the flip component 3 are respectively arranged on both sides of the support component 1, wherein the positioning component 2 is used to assist in positioning the product on the support component 1, ensuring that the flip component 3 can accurately clamp the product, and the flip component 3 drives the product to flip in the vertical plane, ensuring that the outer peripheral surface of the product is detected without dead angles. The detection component 4 is arranged above the support component 1, and is used to automatically detect the surface of the product.

[0037] The support assembly 1 is used to support the product to be tested, and includes a bottom plate 101, a cylinder fixing plate 102, a lifting cylinder 103, a lifting plate 104, a guide sleeve 105, a guide column 106, a carrier plate 107 and a carrier slot 108. The bottom plate 101 is used to fix the positioning assembly 2, the flip assembly 3 and the detection assembly 4, and a bracket welded by an aluminum profile is fixed at the bottom of the bottom plate 101.

[0038] The cylinder fixing plate 102 is fixed on the aluminum profile bracket at the bottom of the base plate 101, the cylinder body of the lifting cylinder 103 is fixed on the bottom of the cylinder fixing plate 102, and the piston rod of the lifting cylinder 103 passes through the cylinder fixing plate 102 and the base plate 101 and is connected to the lifting plate 104. The lifting plate 104 is driven by the lifting cylinder 103 to perform lifting movements, thereby completing the turning over of the product and ensuring that the surface of the product is detected without blind spots.

[0039] like Figure 5 As shown, the carrier plate 107 is fixed on the top of the lifting plate 104 and rises and falls synchronously with the lifting plate 104. The loading slots 108 are arranged at intervals on the top of the carrier plate 107, and the products to be inspected are clamped and placed on the loading slots 108 by a robot.

[0040] The guide sleeve 105 is fixed at the bottom of the base plate 101, and the guide column 106 is fixed at the bottom of the lifting plate 104 and passes through the base plate 101, the guide sleeve 105 and the cylinder fixing plate 102. When the lifting cylinder 103 drives the lifting plate 104 to do lifting and lowering movements, the guide column 106 will be lifted and lowered synchronously in the guide sleeve 105. Relying on the guiding effect of the guide sleeve 105 on the guide column 106, it is ensured that the lifting plate 104 does not shift in position when it is lifted and lowered, thereby improving the accuracy of the subsequent product flipping position.

[0041] The positioning assembly 2 is fixed on the top of the bottom plate 101 and is located on one side of the carrier plate 107. When the product is turned over, the positioning assembly 2 is used to assist in positioning the product on the support assembly 1. The positioning assembly 2 includes a positioning rail 201, a positioning slider 202, a positioning plate 203, a rotating seat 204, a positioning column 205, a positioning hole 206 and a positioning cylinder 207. The positioning rail 201 is fixed on the top of the bottom plate 101 by screw fastening and is perpendicular to the lifting plate 104. The positioning slider 202 is slidably mounted on the positioning rail 201. The positioning plate 203 is fixed on the positioning slider 202 and moves toward the side close to the carrier plate 107 or moves toward the side away from the carrier plate 107 under the drive of the positioning cylinder 207.

[0042] The rotating seat 204 is fixed to the side of the positioning plate 203 close to the carrier plate 107, a bearing is installed in the rotating seat 204, and the positioning column 205 is installed in the bearing of the rotating seat 204. A positioning hole 206 is opened on the side of the positioning column 205 close to the carrier plate 107. When the product is turned over, the positioning cylinder 207 first drives the positioning plate 203 to move toward the side close to the carrier plate 107 until the positioning hole 206 is inserted into the fixed column on the side of the product, completing the positioning of the product, so that the holding block 311 of the turning component 3 can clamp the product.

[0043] The flip assembly 3 is fixed on the bottom plate 101 and is located on the other side of the carrier plate 107. The flip assembly 3 is used to clamp the positioned product and drive the product to flip in the vertical direction. The flip assembly 3 includes a flip rail 301, a flip slider 302, a moving plate 303, a moving cylinder 304, a bearing seat 305, a flip main shaft 306, a flip secondary shaft 307, a clamping block 308, a flip block 309, a clamping slot 310, a holding block 311, a jack 312, a synchronous wheel 313, a synchronous belt 314 and a rotating motor 315. The flip rail 301 is fixed to the top of the bottom plate 101 by screw fastening, the flip slider 302 is slidably mounted on the flip rail 301, the moving plate 303 is fixed on the flip slider 302, and when the moving cylinder 304 drives the moving plate 303 to move, the cooperation between the flip rail 301 and the flip slider 302 ensures the stability of the movement of the moving plate 303 and improves the accuracy of the position when clamping the product.

[0044] A bearing seat 305 is fixed on one side of the moving plate 303 close to the carrier plate 107. The bearing seat 305 has the same number as the number of the carrier slots 108 on the carrier plate 107. The turning spindle 306 is installed in the bearing seat 305. Figure 6 As shown, the flip sub-shaft 307 is integrally connected to one end of the flip main shaft 306, and a driving mechanism is connected to the flip sub-shaft 307 to drive the flip main shaft 306 to rotate. A flip block 309 is installed at one end of the flip main shaft 306 away from the flip sub-shaft 307. The flip block 309 is used to clamp the product on the loading slot 108 and drive the product to flip in the vertical direction.

[0045] One end of the flip main shaft 306 away from the flip secondary shaft 307 is integrally connected with a clamping block 308. Figure 8 As shown, a slot 310 is provided on one side of the flip block 309 to match the block 308. The slot 310 is connected to the block 308 by plugging, and is easy to disassemble. The flip block 309 to match can be replaced according to different products. Moreover, when the flip spindle 306 rotates, the torque can be better transmitted to the flip block 309, thereby driving the product to flip.

[0046] like Figure 6 As shown, the diameter of the flip main shaft 306 is larger than the diameter of the flip secondary shaft 307. Because torque needs to be transmitted at the connection between the flip main shaft 306 and the flip block 309, the flip main shaft 306 with a larger diameter can avoid being twisted off.

[0047] like Figure 7As shown, a group of holding blocks 311 are integrally connected to the side of the flip block 309 away from the flip spindle 306. When the moving cylinder 304 drives the moving plate 303 to move toward the side close to the carrier plate 107, the holding blocks 311 clamp the product, and the fixed column on one side of the product is inserted into the insertion hole 312 of the flip block 309. Under the joint action of the positioning column 205 and the flip block 309, the product clamping work is completed.

[0048] like Figure 2 , 3 As shown, each flip secondary shaft 307 is sleeved with two synchronous wheels 313, and the synchronous belt 314 is wound around the two synchronous wheels 313 on the two adjacent flip secondary shafts 307. The rotating motor 315 is fixed on the moving plate 303 and connected to one of the flip secondary shafts 307. The output torque of the rotating motor 315 is transmitted to the flip secondary shaft 307 through the synchronous wheel 313 and the synchronous belt 314, and then transmitted to the flip block 309 by the flip main shaft 306, and the product is flipped through the flip block 309.

[0049] The detection assembly 4 is fixed on the bottom plate 101 and is located above the carrier plate 107, and is used to automatically detect the surface of the product. The detection assembly 4 includes a support column 401, a first fixing block 402, a first fixing groove 403, a first locking groove 404, a second fixing block 405, a second fixing groove 406, an extension column 407, a third fixing block 408, a third fixing groove 409, a third locking groove 410, a camera mounting plate 411 and a CCD camera 412. The support column 401 is vertically fixed to the top of the bottom plate 101, as shown in FIG. Fig. 9 As shown, the first fixing groove 403 and the first locking groove 404 penetrate the first fixing block 402 and are connected to each other. In actual assembly, the first fixing block 402 is inserted into the support column 401 (specifically, the first fixing groove 403 is inserted into the support column 401). Then, the spacing of the first locking groove 404 is reduced by a locking nut, and the first fixing block 402 is fixed to the support column 401.

[0050] By adjusting the position of the first fixing block 402 in the vertical direction, the distance between the CCD camera 412 and the carrier board 107 can be appropriately adjusted, so as to facilitate the adjustment of the focal length.

[0051] like Fig. 9 As shown, the second fixing block 405 is arranged on one side of the first fixing block 402, and a semi-arc second fixing groove 406 is arranged on the opposite side of the second fixing block 405 and the first fixing block 402, and the extension column 407 is inserted into the second fixing groove 406, and then the extension column 407 is fixed in the second fixing groove 406 by a locking nut.

[0052] like Fig.10As shown, the third fixing groove 409 and the third locking groove 410 pass through the third fixing block 408. During actual assembly, the third fixing block 408 is inserted into the extension column 407 (specifically, the third fixing groove 409 is inserted into the extension column 407), and then the locking nut is used to reduce the spacing of the third locking groove 410 to fix the third fixing block 408 on the extension column 407.

[0053] By adjusting the position of the third fixing block 408 on the extension column 407, the downward shooting coverage area of ​​the CCD camera 412 can be adjusted to ensure that all products on the carrier 107 are within the shooting coverage area of ​​the CCD to avoid detection blind spots.

[0054] The camera mounting plate 411 is fixed on the third fixing block 408 , and the CCD camera 412 is fixed on the camera mounting plate 411 and is arranged downward to photograph the products below.

[0055] The detection principle of the utility model crack automatic detection equipment is as follows:

[0056] First, the robot places the product to be inspected on the loading slot 108 of the loading plate 107, and starts the positioning cylinder 207 and the moving cylinder 304. The positioning cylinder 207 drives the positioning plate 203 to move toward the side close to the loading plate 107, and the moving cylinder 304 drives the moving plate 303 to move toward the side close to the loading plate 107 until the fixed columns on both sides of the product are respectively inserted into the positioning holes 206 and the insertion holes 312, and the product is clamped by the holding block 311 on the flip block 309.

[0057] At this time, the lifting cylinder 103 drives the lifting plate 104 to descend to provide avoidance space for the flipping of the product, and starts the rotating motor 315. The output torque of the rotating motor 315 is transmitted to the flip secondary shaft 307 through the synchronous wheel 313 and the synchronous belt 314, and then transmitted to the flip block 309 by the flip main shaft 306. The product is flipped by the flip block 309, and the entire outer surface of the product is detected for cracks through the CCD camera 412 above. After the detection is completed, the lifting cylinder 103 drives the lifting plate 104 to reset, and the product is put back into the loading slot 108 of the carrier plate 107. The positioning component 2 and the flip component 3 are reset, and the robot can take away the product after detection.

[0058] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model.
