Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0020] Please refer to Figures 1-5 The utility model provides a kind of technical scheme: a middle beam surface stripe quality inspection device, including mounting frame 1, mounting frame 1 is equipped with four symmetrical distributions, the middle part of four mounting frames 1 is equipped with quality inspection mechanism 2, quality inspection mechanism 2 includes: The detection assembly 21 includes an outer frame 211 fixedly installed in the middle of the mounting bracket 1. Two symmetrically distributed upper industrial cameras 212 are detachably mounted on the inner upper surface of the outer frame 211. Side industrial cameras 213 are detachably mounted on both sides of the outer frame 211. Two diagonally distributed bases 215 are fixedly mounted on the inner lower surface of the outer frame 211. A rotating shaft 216 is rotatably mounted on the top of each base 215. Deflection rods 2161 are fixedly mounted on opposite sides of each rotating shaft 216. A lifting plate 217 is provided on opposite sides of the two deflection rods 2161. A drive assembly is provided at the lower part of the lifting plate 217. The upper parts of the two rotating shafts 216... The device is fixedly mounted with a mounting bracket 219. The upper part of each of the two mounting brackets 219 can be detachably mounted with a lower industrial camera 214. The upper industrial camera 212, the side industrial camera 213, and the lower industrial camera 214 are all Hikvision MV-CA013-21UC models. All industrial cameras are connected to the PLC control system of the equipment through an RJ45 Ethernet interface to transmit detection image data. Through image processing algorithms, the shape, size, and position of the stripes can be accurately analyzed. By comparing with standard images, it can quickly determine whether there is extrusion of the stripes, such as stripe width exceeding the normal range or irregular protrusions, which can all be clearly identified. The conveying assembly 22 is located in the middle of the mounting frame 1 and is used to convey the PVC beams that need to be inspected.

[0021] The conveying assembly 22 includes a conveyor belt 221 disposed in the middle of the mounting frame 1. Fixing plates 222 are installed on both sides of the four conveyor belts 221. Tension adjustment components are provided on one side of each fixing plate 222. The four fixing plates 222 are fixedly installed on the lower part of the mounting frame 1. Lifting screws 224 are rotatably installed in the middle of the four mounting frames 1. Servo motors 223 are fixedly installed in the middle of the top of two mounting frames 1. The servo motors 223 are MINSA5 series servo motors, model MSMJ022G1A. They are connected to the PLC control system through servo drivers and receive position and speed control signals from the PLC to achieve precise lifting and positioning of the conveyor belts 221. The two sets of lifting screws 224 are connected by a transmission belt. The middle of the other four fixing plates 222 is threaded onto the upper part of the lifting screws 224.

[0022] The tension adjustment assembly includes a tension screw 226 rotatably mounted on one side of a fixed plate 222. A slider 227 is threadedly mounted on the middle of each tension screw 226. One side of each slider 227 is slidably locked onto one side of the fixed plate 222. Both ends of one side of each conveyor belt 221 are rotatably mounted on one side of the slider 227. By rotating the tension screw 226, the slider 227 is moved to one side, thereby causing one end of the conveyor belt 221 to move accordingly, in order to adjust the tension of the conveyor belt 221.

[0023] The drive assembly includes a cylinder 218 fixedly installed on the lower surface inside the outer frame 211. It adopts an Airtac SC100 cylinder and is connected to the PLC control system through a relay module. It is used to receive the telescopic control signal sent by the PLC to realize the adjustment of the shooting angle of the lower industrial camera 214. The bottom end of the lifting plate 217 is fixedly installed on the drive end of the cylinder 218.

[0024] The lifting plate 217 has a limiting groove 2171 slidably engaged in the middle of both sides. The two ends of the two deflection rods 2161 are slidably engaged in the middle of the limiting groove 2171. The limiting groove 2171 has a trapezoidal cross-section, which can ensure that when the lifting plate 217 moves up and down at the same time, the deflection rods 2161 can slide within the limiting groove, causing them to deflect. At the same time, the trapezoidal cross-section ensures the stability of its sliding inside.

[0025] Two symmetrically distributed limiting rods 225 are fixedly installed in the middle of each of the multiple mounting brackets 1. One side of each of the four fixing plates 222 is slidably locked onto the outer surface of the limiting rods 225. The limiting rods 225 are used to limit the four upper fixing plates 222 to ensure that the upper conveyor belt 221 can move stably up and down under the rotation of the lifting screw 224.

[0026] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0027] During operation, the PVC beam to be inspected is placed on the lower conveyor belt 221. Driven by the servo motor 223, the two lifting screws 224 rotate synchronously through the transmission belt, which drives the two side fixing plates 222 to move downward, thereby driving the upper conveyor belt 221 to move downward, so that it comes into contact with the upper surface of the PVC beam. The upper and lower conveyor belts 221 limit and clamp the PVC beam. Driven by the drive motor, the upper and lower conveyor belts 221 rotate synchronously and in opposite directions (the drive motor is a traditional servo motor, which will not be described in detail here). The PVC beam between the two conveyor belts 221 is then transported to the middle. When it reaches the middle position between the two sets of conveyor belts 221, the upper industrial camera 212, the side industrial camera 213, and the lower industrial camera 214 inspect the upper side surface, the lower surface, and the lower inner side of the PVC beam, respectively. During inspection, the different sizes of the PVC beams and the "U"-shaped cross-section of the structure result in different dimensions of the lower inner sidewalls. Therefore, it is necessary to adjust their angle so that the lower industrial camera 214 can capture images of both the lower surface and the lower inner sidewalls. When adjusting the angle, the lifting plate 217 can be moved up and down by the cylinder 218. When the lifting plate 217 moves upward, it will cause one side of the deflection rod 2161 to move upward under the limit of the limit groove 2171, which in turn causes the rotating shaft 216 to rotate, thereby causing the fixed frame 219 to deflect at an angle. This causes the shooting angle of the lower industrial camera 214 to tilt upward, and vice versa. This adjusts the pitch angle of the lower industrial camera 214.
