[0031] The structure of the driven rotating assembly 14 is similar to that of the active rotating assembly 7 , including the second roller bracket base 146 , the second roller bracket 142 and other parts, and is also used to support and rotate the rubber roller 3 .

[0032] See also Figure 6 , is a detection assembly of an embodiment of the present invention. As shown in the figure, during the detection process, the first detection bracket body 19 is rotatably mounted on the first detection bracket bottom 17 fixedly mounted on the top of the second screw nut 163 through the first detection bracket rotating shaft 18, and the Rockwell hardness tester 20 is fixedly mounted thereon for performing hardness detection on the surface of the rubber roller 3. At the same time, the corresponding detection bracket part is also fixedly mounted on the top of the first screw nut 153, including the second detection bracket bottom 25, the second detection bracket rotating shaft 26 and the second detection bracket body 21, and the laser rangefinder 22 fixedly mounted thereon is used to measure the outer diameter and length of the rubber roller 3.

[0033] The first motor 4, the cleaning nozzle 13, the first lifting piston 75, the photoelectric sensor 10, the second lifting piston 145, the second motor 151, the third motor 161, the first detection bracket shaft 18, the Rockwell hardness tester 20, the laser rangefinder 22, and the second detection bracket shaft 26 are all electrically connected to the controller 9.

[0034] The detection process is as follows: In the detection process, the rubber roller 3 is first placed in the groove of the rubber roller bracket 6 to ensure that it is stably placed on the rubber roller bracket 6. Subsequently, the controller 9 controls the transmission mechanism (not shown in the figure) to start, so that the rubber roller bracket 6 enters the appearance detection device along the direction of the guide rail body 11. When the rubber roller 3 reaches the specified detection position, the photoelectric sensor 10 detects that the rubber roller bracket 6 has reached the specified position and sends a ready signal to the controller 9, indicating that the next step can be performed. The controller 9 controls the transmission mechanism to stop, and at the same time controls the first lifting piston 75 and the second lifting piston 145 to lift synchronously, lift the rubber roller 3 from the rubber roller bracket 6, and make the rubber roller 3 separate from the rubber roller bracket 6 to achieve the best detection height. The first motor 4 is started, and through the rotation of the transmission shaft 5, the active roller shaft 71 is driven to rotate through the belt, and the active roller shaft 71 drives the rubber roller 3 to start rotating at a uniform speed through close contact with the rubber roller 3. During the rotation of the rubber roller 3, the cleaning nozzle 13 sprays compressed air, and the cleaning brush 8 thoroughly cleans the surface of the rubber roller to remove all surface impurities and contaminants to ensure the accuracy of subsequent detection. After the cleaning is completed, the controller 9 sends a signal to control the rotation shaft 18 of the first detection bracket and the rotation shaft 26 of the second detection bracket to rotate, so that the Rockwell hardness tester 20 and the laser rangefinder 22 are adjusted to the detection position to prepare for the next step of detection. While the rubber roller 3 continues to rotate, the laser rangefinder 22 starts to work and measures the outer diameter of the rubber roller 3 to ensure that its size meets the standard. The second motor 151 starts to drive the first screw nut 153 to move axially along the first screw 154. During this process, the laser rangefinder 22 continues to work to measure the length of the rubber roller 3 to ensure that its size is within the allowable tolerance range. Afterwards, a high-precision camera (not shown in the figure) is used to detect whether there are any tiny defects on the entire exterior of the rubber roller 3, such as cracks, depressions, etc., which further improves the accuracy and reliability of the detection. The third motor 161 starts to drive the second screw nut 163 to move axially along the second screw 164. The second screw nut 163 drives the Rockwell hardness tester 20 to perform multi-point hardness detection on the surface of the rubber roller 3 to evaluate its material performance and durability, and transmit the hardness data to the controller 9. If the test result shows that the surface hardness of the rubber roller 3 is higher than the set value, this usually indicates that the rubber roller 3 has been stored in the air for too long, resulting in hardening of its surface material; in order to restore the normal use state of the rubber roller 3, it is necessary to grind its surface; the purpose of grinding is to remove the hardened surface layer and restore the rubber roller 3 to the appropriate softness and hardness, so as to ensure that it can normally cooperate with the contact surface during use and achieve the expected transmission or coating effect. On the contrary, if the test result shows that the surface hardness of the rubber roller 3 is lower than the set value, this often means that the surface of the rubber roller 3 has been impregnated with drugs or other solvents during storage; such impregnation will cause the material properties of the surface of the rubber roller 3 to change, which may affect its use performance. It is necessary to remove the damaged surface and select a solvent-resistant material to re-coat the rubber roller 3.This ensures that the properties of the rubber roller 3 will not change again when it comes into contact with similar drugs or solvents, thereby maintaining its stable performance. Subsequently, the laser rangefinder 22 detects the circular runout of the rubber roller 3 to evaluate the stability of the rubber roller during rotation. After the detection is completed, the controller 9 sends a signal to control the first lifting piston 75 and the second lifting piston 145 to descend, and at the same time controls the first detection bracket shaft 18 and the second detection bracket shaft 26 to rotate, so that the Rockwell hardness tester 20 and the laser rangefinder 22 return to the initial position to prevent collision with the rubber roller bracket 6. Finally, the rubber roller 3 falls back into the groove of the rubber roller bracket 6, and the controller 9 sends a signal to control the transmission mechanism to start, and the rubber roller bracket 6 leaves the appearance detection device, ending the entire detection process.

[0035] The above embodiment also provides a method for circular runout detection applied to the rubber roller appearance detection device, and the method has the following detailed steps:

[0036] Step S101, the laser rangefinder 22 is installed on the second detection bracket body 21 to ensure that it does not move during the detection process. Then the laser rangefinder 22 is accurately calibrated, and its measurement parameters and angles are adjusted to ensure the accuracy of the measurement results. At the same time, the second screw nut 163 drives the Rockwell hardness tester 20 to move to a preset position, ready to perform surface hardness detection on the rubber roller 3. After the calibration is completed, the laser rangefinder 22 is aligned with the preset detection point of the rubber roller 3, ready to start measurement.

[0037] Step S102, the rubber roller 3 rotates, and the laser rangefinder 22 starts to detect its circular runout. The laser rangefinder 22 will emit a laser beam, irradiate the surface of the rubber roller 3, and measure the time for the laser to reflect back, so as to calculate the distance from the laser rangefinder 22 to the surface of the rubber roller 3. At the same time, the Rockwell hardness tester 20 starts to test the hardness of the surface of the rubber roller 3 to evaluate its material properties and durability. If the test result shows that the surface hardness of the rubber roller 3 is higher than the set value, this may indicate that the rubber roller 3 has been stored in the air for too long, and the surface material has hardened, causing the laser rangefinder 22 to encounter greater surface roughness during measurement, thereby affecting the measurement accuracy. In order to cope with this situation, the controller 9 will adjust the measurement parameters of the laser rangefinder 22 to compensate for the measurement deviation caused by the change in hardness. This distance will change as the rubber roller 3 rotates, and the laser rangefinder 22 will transmit this real-time data to the controller 9 for recording. The laser distance meter 22 goes around the outer circle of the rubber roller 3 to draw a curve of the distance from the laser distance meter 22 to the surface of the rubber roller 3, and the curve is placed on the image for subsequent analysis.

[0038] Step S103, in order to accurately evaluate the circular runout of the rubber roller 3, the laser rangefinder 22 will take multiple points on the rubber roller 3 for repeated measurement. These points should be evenly distributed on the surface of the rubber roller 3 to ensure the comprehensiveness of the measurement. Similarly, the laser rangefinder 22 will plot these measurement data into a curve and superimpose them with the previous curve. At the same time, the Rockwell hardness tester 20 will also perform hardness measurement at these points and transmit the hardness data to the controller 9. By comparing these curves and hardness data, the circular runout and hardness change of the rubber roller 3 at different positions can be determined.

[0039] Step S104: The controller 9 generates a circular runout test table and a hardness test table based on all the collected data. These two tables list the distance data, hardness data and corresponding curve images of each measuring point in detail. By comparing the data in the test table with the preset standard range, the controller 9 can determine whether the circular runout and hardness of the rubber roller 3 are within the normal range. If the data exceeds the standard range, it means that there is a problem with the circular runout or hardness of the rubber roller 3.

[0040] Step S105: When the controller 9 determines that the surface hardness of the rubber roller 3 is high, the controller 9 will further analyze the influence of the hardness on the circular runout measurement. Since the high hardness may increase the surface roughness, thereby affecting the measurement accuracy of the laser rangefinder 22, the controller 9 will adjust the measurement parameters or adopt other compensation measures to ensure the accuracy of the circular runout measurement. At the same time, the controller 9 will also determine whether the absolute height difference between different curves is less than the standard value to evaluate the circular runout difference of the rubber roller 3 at different positions. Only when the curve as a whole does not exceed the standard range and the absolute height difference between different curves is less than the standard value, can the circular runout of the rubber roller 3 be considered qualified.

[0041] Step S106: When the controller 9 determines that the surface hardness of the rubber roller 3 is low, it will consider that the surface of the rubber roller may be more susceptible to external factors such as drugs or solvents. Such influence may not only lead to inaccurate hardness measurement results, but also change the properties of the rubber roller surface material, thereby affecting the accuracy of the circular runout measurement.

[0042] Step S107, according to the judgment result, the system will make a corresponding response. If the data is within the standard range, and the absolute height difference between the curves meets the requirements, it means that the circular runout and hardness of the rubber roller 3 are normal, and the controller 9 will not issue an alarm signal. If the data exceeds the standard range, or the absolute height difference between the curves is too large, it means that there is a problem with the circular runout or hardness of the rubber roller 3. The controller 9 will trigger an alarm and notify the staff to check and adjust. The operator can perform corresponding maintenance or replacement work on the rubber roller 3 according to the prompts. If the problem is caused by low hardness, it may be necessary to select solvent-resistant materials to re-coat the rubber roller 3 to ensure its stable performance.
