DETAILED DESCRIPTION
[0019] In order to more clearly understand the above-mentioned purposes, 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. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.
[0020] 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 scope of protection of the present invention is not limited to the specific embodiments disclosed below.
[0021] like Figures 1 to 4 As shown, an automatic detection device for impurity welding spots of plate roller steel is used to detect the plate roller 2, including a cabinet 1, a conveying motor 3, a rotating seat 4, a detection mechanism and rollers 6. Two groups of rollers 6 are symmetrically arranged on the upper surface of the cabinet 1, the conveying motor 3 is arranged on the rollers 6, and the conveying motor 3 is used to drive the rollers 6 to rotate. Two groups of rotating seats 4 are arranged between the two rollers 6, and the rotating seat 4 is fixedly set on the upper surface of the cabinet 1. The two rotating seats 4 and the rollers 6 on both sides are set in the same straight line. The detection mechanism is set between the two rotating seats 4, the plate roller 2 is placed through the detection mechanism, and the two ends of the plate roller 2 are placed on the rotating seat 4 and the rollers 6.
[0022] During the process of being transported by the support roller 6, the plate roller 2 is driven by the rotating seat 4 to rotate in a circular motion.
[0023] Preferably, the detection mechanism includes a detection frame 5, a detection head 504 and a limit seat 506. The detection frame 5 is fixedly set on the upper surface of the cabinet 1, and the limit seat 506 is slidably set in the detection frame 5 in the vertical direction. The detection head 504 is set at the bottom of the limit seat 506. There are multiple groups of probes 504 arranged linearly at the bottom of the detection head 504. The detection head 504 is set in the limit seat 506 through the block 503.
[0024] The detection head 504 is mounted on the limit seat 506 by means of a clamping block 503. When the detection head 504 malfunctions or needs to be replaced with a different-sized detection head 504 to accommodate a specific detection task, the operator can conveniently remove the detection head 504 from the limit seat 506. The limit design of the clamping block 503 ensures that the detection head 504 is securely mounted and prevents it from loosening or shifting during the inspection of the plate roller 2. At the same time, it ensures ease of maintenance and replacement, thereby reducing equipment maintenance costs and downtime.
[0025] Preferably, the detection frame 5 adopts a U-shaped frame, the opening side of the detection frame 5 is set downward, the outer side of the limit seat 506 is set in contact with the inner wall of the detection frame 5, and the limit blocks 502 are set on both sides of the limit seat 506. Sliding through holes matching the limit blocks 502 are opened on both sides of the detection frame 5.
[0026] The stop block 502 limits the lateral displacement of the stop base 506 during the lifting and lowering process, ensuring that the stop base 506 always moves smoothly in the vertical direction. This greatly improves the structural stability of the stop base 506 during adjustment, allowing the detection head 504 to accurately locate the area to be detected on the plate roller 2, avoiding detection errors caused by shaking or offsetting the stop base 506, thereby ensuring the accuracy of the detection results.
[0027] Preferably, a screw is rotatably mounted on the top of the limit seat 506. The top of the screw extends through the top of the detection frame 5 and is connected to a handwheel 501. The operator can easily and precisely adjust the height of the limit seat 506 by manually turning the handwheel 501. This design provides excellent operational convenience, allowing for rapid adaptation to the testing requirements of rollers 2 of varying diameters without the need for complex auxiliary tools or additional power equipment, significantly improving efficiency during the test preparation phase.
[0028] Preferably, the detection head 504 is provided with a cavity 508 that matches the probe 505. The probe 505 is slidably disposed in the cavity 508 and is connected to the bottom surface of the cavity 508 via a spring 509. Regardless of whether the surface of the plate roller 2 is flat or not, the probe 505 can adapt to its contour changes. This design ensures comprehensive detection. Even if there are tiny bumps or impurity welds on the surface of the plate roller 2, the probe 505 can sense them and make contact with them in a timely manner, effectively avoiding detection blind spots and improving detection reliability.
[0029] Preferably, a distance sensor 507 is provided on the inner bottom surface of the cavity 508 and is disposed within the spring 509. Distance sensor 507 can accurately monitor the position changes of the probe 505 in real time and convert this data into an electrical signal for output. Compared to conventional detection methods, this sensor significantly improves detection accuracy and can quantify the degree of surface unevenness of the plate roller 2, providing more accurate data support for determining the size and depth of impure solder joints, thereby facilitating a more precise assessment of the quality of the plate roller 2.
[0030] After the equipment is turned on, the conveying motor 3 begins to operate, driving the rollers 6 to rotate. The plate roller 2, placed on the rollers 6, is transported forward along the cabinet 1 due to the friction of the rollers 6. The conveying motor 3 provides stable power, ensuring that the plate roller 2 can move at a constant speed to the subsequent inspection position. After the plate roller 2 is transported to the specified position, the rotating seat 4 begins to operate. The rotating seat 4 uses mechanical transmission to rotate the plate roller 2 in a circular motion around its own axis. This rotation method allows the surface of the plate roller 2 to be fully exposed to the inspection mechanism, creating conditions for comprehensive inspection of the surface condition of the plate roller 2. The limit seat 506 in the inspection mechanism can be adjusted in height through the cooperation of the screw and handwheel 501. Turning the handwheel 501 rotates the screw, driving the limit seat 506 up and down to adapt to the inspection requirements of plate rollers 2 of different diameters. The limit blocks 502 on both sides of the limit seat 506 ensure that the position of the limit seat 506 is stable during adjustment, allowing the inspection head 504 to accurately locate the area of the plate roller 2 to be inspected. The detection head 504 is mounted within the stop seat 506, and its internal structure plays a key role in detection. Cavities 508 containing springs 509 are evenly distributed within the detection head 504. A probe 505 is mounted at one end of the spring 509 and extends beyond the detection head 504. When the detection head 504 is aligned with the surface of the plate roller 2, the elastic force of the spring 509 forces the probe 505 to press tightly against the surface of the plate roller 2. As the plate roller 2 rotates, if foreign solder spots on the surface of the plate roller 2 cause unevenness, the probe 505 will move with this unevenness, compressing or stretching the spring 509. A distance sensor 507, located at the center of the cavity 508, monitors the position changes of the probe 505 in real time and collects this data. By analyzing this data, it is possible to determine whether there are foreign solder spots on the surface of the plate roller 2, as well as their location and size, completing the entire detection process.
[0031] The above only describes in detail the preferred embodiments of the present invention, but the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by ordinary technicians in this field, various changes can be made without departing from the purpose of the present invention, and various changes should be included in the scope of protection of the present invention.
