It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0030] 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 than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. Example

[0031] like Figure 1-4As shown, the utility model provides a hot rolled plate hemming defect detection device, including a workbench 1, a conveying device 2 is arranged on the workbench 1, and lifting mechanisms 3 are respectively arranged on both sides of the conveying device 2, and two stabilizing plates 4 are respectively fixed on the two lifting mechanisms 3, and clamping components 6 are respectively rotatably installed on the two stabilizing plates 4, and a turning mechanism 7 is connected to one clamping component 6, and the turning mechanism 7 is installed on one lifting mechanism 3, and a gantry 8 connected to the workbench 1 is arranged above the conveying device 2, and a camera body 10 is arranged on the gantry 8, and a display 11 is arranged on the workbench 1, and the display 11 is electrically connected to the camera body 10;

[0032] The flipping mechanism 7 includes a fixed frame 71 connected to the lifting mechanism 3, a sleeve 72 and a spring 73 connected to the fixed frame 71, a power rod 74 movably passing through the sleeve 72, a driving block 75 connected to the bottom end of the power rod 74, a push plate 76 movably passing through the driving block 75 and connected to the spring 73, and a ratchet 77 abutting against one end of the push plate 76. The ratchet 77 is fixedly connected to a clamping assembly 6, and a reset spring 78 is fixedly connected to the inner cavity of the sleeve 72. The other end of the reset spring 78 is connected to a pressure plate 79. The pressure plate 79 is arranged in the inner cavity of the sleeve 72 and fixedly connected to the power rod 74.

[0033] In this embodiment, the clamping assembly 6 includes a rotating shaft 61 rotatably mounted on the stabilizing plate 4, a positioning slot block 62 connected to one end of the rotating shaft 61, a bidirectional screw 63 rotatably mounted in the positioning slot block 62, a clamping plate 64 connected to the forward and reverse threaded sections of the bidirectional screw 63, and a handle 65 arranged on the outer side of the positioning slot block 62 and connected to one end of the bidirectional screw 63. A limiting slot 66 is provided on the inner wall of the positioning slot block 62, and a limiting block is slidably arranged in the limiting slot 66, and the limiting block is fixedly connected to the clamping plate 64.

[0034] Specifically, by utilizing the design of the limiting groove 66, the two clamping plates 64 can be driven to move closer to or farther from each other when the bidirectional screw rod 63 rotates, thereby achieving the clamping and fixing of the hot rolled plate, and the effect of clamping and fixing hot rolled plates of different thicknesses can be achieved. Based on this, when the clamping plate 64 is in use, an anti-slip textured rubber pad can be provided on its surface to increase the friction between the clamping plate 64 and the hot rolled plate, thereby ensuring the stability of the hot rolled plate when it is flipped.

[0035] In this embodiment, the lifting mechanism 3 includes a cylinder 31 installed on the workbench 1, a lifting plate 32 connected to the output end of the cylinder 31, guide rods 33 connected to the two end sides of the lifting plate 32, and mounting plates 34 respectively connected to the guide rods 33, and the fixing frame 71 is fixedly installed on the mounting plate 34.

[0036] Specifically, two cylinders 31 and lifting plates 32 are provided. When the two cylinders 31 work simultaneously to drive the lifting plates 32 to rise, the lifting plates 32 can drive the mounting plates 34 to rise through the guide rods 33, thereby lifting the clamped hot rolled plate. After the hot rolled plate is lifted, there is a certain space between it and the conveying rollers 24, which can be used to meet the requirements of the flipping of the hot rolled plate. When the hot rolled plate is flipped, the camera body 10 takes pictures of different surfaces or angles of the hot rolled plate, and transmits the pictures to the display 11 for observation and detection by the staff.

[0037] In this embodiment, a linear module 9 is fixedly installed on the gantry 8, and a camera body 10 is fixedly installed on a slide of the linear module 9. Specifically, the linear module 9 is used to drive the movement of the camera body 10, so that the camera body 10 can take a more comprehensive picture of the hot rolled plate.

[0038] In this embodiment, the conveying device 2 includes a motor 21 installed on the workbench 1, a sprocket 22 connected to the output end of the motor 21, a transmission chain 23 engaged with the sprocket 22, and a plurality of conveying rollers 24 driven by the transmission chain 23. Specifically, the motor 21 can drive the plurality of conveying rollers 24 to rotate through the sprocket 22 and the transmission chain 23. The linkage of this technical structure is biased towards the prior art and is not elaborated in detail herein. When the plurality of conveying rollers 24 are installed, the height of the conveying rollers 24 should be higher than the height of the guard plate on the conveying device 2, so as to meet the conveying of the hot rolled plate.

[0039] In this embodiment, the camera body 10 and the rotating shaft 61 are on the same vertical plane. Specifically, when the hot rolled plate is clamped, fixed and flipped, the camera body 10 can fully capture different surfaces and angles of the hot rolled plate, which is conducive to comprehensive detection and ensures the production quality of the hot rolled plate.

[0040] In this embodiment, support legs are respectively connected to the four corners of the bottom of the workbench 1, which are specifically used to stabilize the workbench 1, prompt the lifting mechanism 3 and the turning mechanism 7 on the workbench 1 to work, and realize the detection of hot rolled plates.

[0041] The working principle and use process of the utility model are as follows: when in use, the hot coiled plate must first be placed on the conveying roller 24 for conveying. During the conveying, the two ends of the hot coiled plate extend to the two sides of the guard plate of the conveying device 2. When the hot coiled plate is conveyed to the clamping assembly 6, the conveying device 2 is stopped by manual control, and then the screw handle 65 is manually turned so that the screw handle 65 drives the bidirectional screw rod 63 to rotate, so that the two clamping plates 64 can approach each other to clamp and fix the two ends of the hot coiled plate respectively. During this period, the linear module 9 can drive the camera body 10 to move back and forth to achieve a comprehensive shot of one side of the hot coiled plate, and transmit the shot data to the display 11 for display. After clamping and fixing, the cylinder 31 works so that the lifting plate 32 can drive the mounting plate 34 to rise via the guide rod 33, so that the clamping assembly 6 drives the hot coiled plate to leave the conveying device 2. After reaching a certain height, the power rod 74 is manually pushed so that the dynamic The locking cam 75 is pressed against the locking cam 76 to release the locking cam 78, thereby locking the locking cam 76 in the locking cam 76. The locking cam 76 is pressed against the support cam 74 to release the locking cam 78.
