Description

Technical Field

[0001] This utility model relates to the field of rollers, and in particular to a roller detection device. Background Technology

[0002] A roller is a cylindrical rod-shaped object, usually made of metal, ceramic or other materials, and is widely used in industrial production.

[0003] A roller inspection device is a specialized device used to inspect the quality, performance, or condition of rollers.

[0004] The existing roller inspection device has the following shortcomings:

[0005] After the rollers are processed, their surfaces need to be inspected by a testing device to ensure that they meet the requirements for use, thereby ensuring the smooth progress of subsequent work. However, in the existing technology, most inspection methods rely on manual visual inspection to observe surface defects one by one. This method is not only time-consuming and laborious, but also significantly reduces the efficiency of operation, which has an adverse impact on the overall work progress and effect.

The outer wall thread of the bidirectional lead screw passes through the outer wall of the first slider. The output end of the second servo motor is fixedly connected to one end of the bidirectional lead screw. Through the bidirectional lead screw and the second servo motor, a set of first sliders can be driven to move closer to each other or in opposite directions, thereby driving the corresponding movable plate to move as well, so that a set of rubber pads and fixed plates can normally contact the two sides of the roller to complete their fixation.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, by working together with an industrial camera and an infrared thermal imager, the surface defects (glaze peeling, impact damage) and internal heat conduction abnormalities (such as pores and crack extension) of the roller can be detected simultaneously, avoiding missed detections by a single technology and improving the overall detection efficiency.

[0026] like Figure 2 As shown, the bottom of the base 101 is fixedly connected to the support legs 103, and the outer wall of the support legs 103 is fixedly connected to the anti-slip pads 104. The infrared thermal imager 121 is respectively set on the top of the base 101 and on both sides of the movable plate 106. The support legs 103 and anti-slip pads 104 can improve the overall stability during use.

[0027] like Figure 2 and Figure 4 As shown, an LED light board 116 is fixedly installed on the outer wall of the first inclined block 115, a PLC controller 108 is fixedly installed on the top of the base 101, and a set of rubber pads 119 are fixedly connected to the outer wall of the fixed plate 117. The PLC controller 108 is electrically connected to the components to control the opening and closing of the components.

[0028] like Figure 2 and Figure 3 As shown, a bidirectional lead screw 113 is movably inserted into the inner wall of the base 101, and a second servo motor 105 is fixedly installed on one side of the outer wall of the base 101. The outer wall thread of the bidirectional lead screw 113 passes through the outer wall of the first slider 114. The output end of the second servo motor 105 is fixedly connected to one end of the bidirectional lead screw 113. Through the bidirectional lead screw 113 and the second servo motor 105, a set of first sliders 114 can be driven to move closer to each other or in the opposite direction, and the corresponding movable plate 106 can be moved together, so that a set of rubber pads 119 and fixed plate 117 can normally contact the two sides of the roller, and complete their fixation.

[0029] like Figure 3As shown, the inner wall of the base 101 is slidably connected to a second slider 111, and a set of guide rods 112 are fixedly connected to the inner wall of the base 101. The outer wall of the guide rods 112 is slidably connected to the inner wall of the second sliders 111. By setting the second sliders 111 and guide rods 112, the stability of the movable plate 106 when it moves back and forth can be improved.

[0030] like Figure 2 As shown, a set of positioning grooves 102 are provided on the top of the base 101. The positioning grooves 102 facilitate the user to connect the placement box 201 to the base 101.

[0031] like Figure 5 As shown, the connection structure 2 includes a placement box 201. A set of positioning blocks 202 are fixedly connected to the outer wall of the placement box 201. The outer wall of the positioning blocks 202 is slidably connected to the inner wall of the positioning groove 102. Through the placement box 201, the user can put the workpiece into it to avoid frequent movement and picking.

[0032] The operating method and working principle of this device are as follows: First, the cooled ceramic roller is placed between two fixed plates 117. The operator starts the second servo motor 105 through the control button of the PLC controller 108. This motor drives the bidirectional lead screw 113 to rotate. By utilizing the reverse thread on the surface of the lead screw to engage with the thread of the first slider 114, a set of first sliders 114 can move synchronously in opposite directions, thereby driving the movable plate 106 to move. This causes the rubber pad 119 and the fixed plate 117 to contact and fix the roller on both sides. At the same time, the second slider 111 slides on the guide rod 112 to improve the stability of the movement of the movable plate 106. After fixing, the first servo motor 107 drives the fixed plate 117 to rotate, causing the roller to rotate continuously 360 degrees. The detection system adopts multi-sensor fusion technology of machine vision and infrared thermal imaging. The industrial camera 110 is based on machine vision... The optical detection algorithm uses a uniform surface light source provided by the LED light panel 116 to optically detect defects such as glaze peeling and impact damage on the roller surface. The infrared thermal imager 121 simultaneously collects the temperature field data of the roller surface and uses the principle of heat conduction to detect hidden defects such as internal pores and cracks. The two detection technologies complement each other and effectively solve the problem of missed detection by a single detection method. After the detection data is converted into electrical signals by the sensor, it is transmitted to the PLC controller 108 in real time for data processing and analysis. The operator can view the detection data on the display screen on the PLC controller 108. In addition, the PLC controller 108 adopts modular programming logic and realizes the timing coordination of each actuator through preset control program to ensure the automated operation of the detection process. At the same time, the movable plate 106 can be adjusted by the bidirectional lead screw 113 to adapt to rollers of different lengths, improving the applicability of the device.

[0033] The LED light board 116, PLC controller 108, first servo motor 107, second servo motor 105, industrial camera 110, and infrared thermal imager 121 used in this application are all common equipment on the market and are well known to those skilled in the art.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
