Description

Technical Field

[0001] The present invention relates to the technical field of shaft detection equipment, and specifically provides a detection device and method for electro-galvanized conductive rollers. Background Art

[0002] Electro-galvanized conductive rollers play a very important role in the electro-galvanizing production process. They must have good electrical conductivity to ensure that the current can be transmitted stably and evenly, guaranteeing the normal progress of the electroplating process. Poor electrical conductivity of the conductive roller will lead to uneven current distribution, and then the coating thickness will be inconsistent, affecting the product quality. The hollow cylindrical conductive roller is also a commonly used conductive roller. An internal wire-passing channel is formed, and a power cord can be installed, which can optimize the current inflow path, making the current distribution more uniform when it shunts from the middle section to both ends, greatly avoiding the occurrence of edge burning phenomenon.

[0003] In order to ensure that the conductive roller has good electrical conductivity, it is necessary to detect the roundness and concentricity after its production to ensure that the conductive roller meets the required standards. The dial indicator is a common detection instrument, which includes two parts: a detector and a display pointer dial. The end of the lever detector is pressed against the surface of the conductive roller through a clamping device. During the detection, the conductive roller is placed horizontally, and the roundness is detected by rotating the conductive roller. If the pointer of the display dial of the dial indicator moves within the standard range, it means that the conductive roller meets the production standards. However, for the hollow cylindrical conductive roller, the pointer dial of the dial indicator greatly affects the detection range of the dial indicator, resulting in that it can only detect within a certain range at the end of the conductive roller. Although it can be solved by reducing the volume of the pointer dial, during the detection process, the operator cannot view the dial data, and the current horizontal detection method will also cause the cantilever effect, affecting the detection error of the dial indicator.

Specific embodiments

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] In order to enable those in the technical field to better understand the solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] An electro-galvanized conductive roller detection device, as Figure 1 shown, includes a movable detection platform 1. A rotatable placement table 2 for placing the conductive roller is assembled on the detection platform 1 and can be driven to rotate by an external motor. It should be noted that the rotation speed of the placement table 2 should not be too fast. In this embodiment, the shape of the placement table 2 is set to be circular. A leveling mechanism for adjusting and supporting the axial placement of the conductive roller is assembled on the surface of the placement table 2 to ensure that the lower surface of the conductive roller is flush with the surface of the placement table 2. A clamping mechanism for clamping and limiting the conductive roller is assembled on the surface of the detection platform 1 to prevent the conductive roller from shifting during the detection process;

[0036] A lever detector 3 for abutting against the surface and / or inside of the conductive roller is assembled on the detection platform 1. The lever detector 3 is a prior art and will not be elaborated in this embodiment. The lever detector 3 is controlled by a lifting mechanism to move longitudinally and detect along the surface of the conductive roller. A display mechanism is installed on the side of the lever detector 3 for recording and displaying the detection data of the lever detector 3. Different from the traditional dial indicator, when the lever detector 3 moves out of the inside of the conductive roller, it is still possible to judge whether the conductive roller is standard by checking the display mechanism.

[0037] As Figures 5 - 7 shown, the display mechanism includes a slidable tooth column 4 meshing with the internal gear of the lever detector 3. A protective shell 6 with a plurality of movable scale plates 5 on its surface is assembled on the side of the lever detector 3. In the initial state, the scale plate 5 is located inside the protective shell 6. When the scale plate 5 protrudes from the surface of the protective shell 6, it indicates that there is an error between a certain position inside the conductive roller and the standard value. On one side of the tooth column 4 relative to the tooth, there is a triangular pressing block 7 for abutting against the surface of the scale plate 5 and moving it. As the tooth column 4 moves, it will drive the pressing block 7 to move. As Figures 6 - 8 shown, the recessed position on the side of the scale plate 5 is installed with a positioning block 8 with a hemispherical end through a spring. In the initial state, the spring is in a normal state, and the hemispherical part of the positioning block 8 is located outside the recessed position. There are two card slots 9 along the moving direction of the scale plate 5 at the position of the lever detector 3 corresponding to the positioning block 8. The positioning block 8 abuts inside one of the card slots 9. When the scale plate 5 moves, the card slot 9 squeezes the positioning block 8, and at this time the spring is in a compressed state until the positioning block 8 moves to the position of the next card slot 9. At this time, the scale plate 5 protrudes from the surface of the protective shell 6. A movable zero scale 10 is arranged on the side of the lever detector 3, and the zero scale 10 is fixed by friction. Before each detection, the position of the zero scale 10 needs to be adjusted, and it is convenient to read by zero calibration.

[0038] First, the lever detector 3 needs to be zero-calibrated. The detection end on the surface of the lever detector 3 is abutted against the surface of the conductive roller. At this time, the internal gear of the lever detector 3 will rotate, so that the tooth column 4 moves longitudinally. The pressing block 7 will press the scale plate 5 within its path range, causing the positioning block 8 to move into the other card slot 9. At this time, the position of the last moved positioning block 8 is regarded as the zero point, and the zero scale 10 is moved to align with this position. Then, all the scale plates 5 are pressed into the protective shell 6. When the lever detector 3 moves, the rotation of its detection end can cause the tooth column 4 to move, thereby moving the scale plate 5 out of the protective shell 6. The tester can judge whether the roundness and concentricity of the conductive roller are within the allowable error range by reading the scale plate 5.

[0039] As Figures 2 - 3As shown, the leveling mechanism includes at least three sliders 11 arranged in a circular array, and need to be arranged in a circle with the center of the storage table 2. The surface of the slider 11 is installed with a leveling lamp 36 that can emit laser, and the laser emitted by the leveling lamp 36 is vertically upward. The surface of the slider 11 is installed with a stud 12 that spirally rotates on the slider 11. By rotating the stud 12, the height of its top from the storage table 2 can be adjusted. A truncated cone-shaped support column 13 is set on the top of the stud 12. The smaller the top area of ​​the support column 13, the more the support of the conductive roller by the three support columns 13 is in a standard vertical state. When the laser emitted by the leveling lamp 36 is not flush with the surface of the conductive roller, the corresponding stud 12 is adjusted to make the support column 13 rise or fall to ensure that the conductive roller is in a completely vertical state.

[0040] like Figure 3 As shown, the surface of the storage table 2 is provided with the same number of track grooves 14 corresponding to the position of the slider 11. The path direction of the track groove 14 is the radius direction of the storage table 2. A guide rod 15 for limiting the slider 11 is installed inside the track groove 14. The slider 11 is sleeved on the surface of the guide rod 15 and moves. The slider 11 is completely located inside the track groove 14. For conductive rollers of different diameters, the inspection personnel can change the position of the support column 13 by moving the slider 11 to ensure that the support column 13 can rest against the bottom of the conductive roller.

[0041] like Figure 2 and Figure 4 As shown, the clamping mechanism includes at least three rotatable threaded rods 16, and a concave mounting groove 24 is provided on the surface of the detection platform 1 at the position corresponding to the threaded rod 16. The threaded rod 16 is installed inside the mounting groove 24 through a bearing to ensure that the threaded rod 16 can rotate but does not generate displacement. A rotatable circular shaft 20 is installed at the corresponding positions of the three threaded rods 16 inside the detection platform 1, and the ends of the circular shaft 20 and the threaded rod 16 are fixedly sleeved with mutually meshing bevel gears 21. The surface of the circular shaft 20 is also fixedly sleeved with a spur gear 22 for transmission, and the three spur gears 22 are connected in transmission through a gear ring 23. A mounting seat 17 with a side wall that fits the inner wall of the mounting groove 24 is threadedly sleeved on the surface of the threaded rod 16, and a positioning rod 37 with a ball 18 on one end is installed on the inner side of the mounting seat 17 through a torsion spring. An inclined inclined plate 25 is installed on one side of the interior of the mounting groove 24, and the ball 18 rests on the surface of the inclined plate 25. A crank 19 for driving it to rotate is installed at one end of one of the threaded rods 16.

[0042] Rotate the crank 19 to drive the corresponding threaded rod 16 to rotate. Thus, through the transmission of the bevel gear 21, the corresponding spur gear 22 rotates. Then, through the transmission of the toothed ring 23, all the spur gears 22 meshing with it rotate, indirectly realizing the rotation of all the threaded rods 16. Due to the limitation of the mounting groove 24 on the mounting seat 17, it is ensured that the mounting seat 17 moves along the axial direction of the threaded rod 16. At this time, the inclined plate 25 exerts a squeezing effect on the ball 18 and the positioning rod 37, causing the positioning rod 37 to slowly tilt up until the ball 18 abuts against the surface of the conductive roller for clamping and fixing. The ball 18 does not affect the self-rotation of the conductive roller. During this process, the torsion spring is in a compressed state. Therefore, the clamping and fixing of the conductive roller can be realized through the elastic force. At the same time, when removing the clamping force, it only needs to rotate the crank 19 in the reverse direction.

[0043] As Figure 1 and Figure 9 shown, the lifting mechanism includes a movable plate 26 that can be lifted. The surface of the movable plate 26 is provided with a positioning long plate 28 with a plurality of through grooves 27 on its surface. The positioning long plate 28 can be set in multiple sections and can be selectively spliced and extended during use. The surface of the positioning long plate 28 is provided with an adjusting component that can adjust the rotation angle of the lever detector 3. Through the adjusting component, the detection end of the lever detector 3 abuts against the surface of the conductive roller for use with conductive rollers of different diameters. Both the adjusting component and the surface of the movable plate 26 are clamped inside the through groove 27 by L-shaped elastic pieces 29. At least two groups of elastic pieces 29 are provided on the movable plate 26, and two positioning long plates 28 are installed to detect the inner wall and the outside of the conductive roller respectively. If it is for a shaft-type conductive roller, only one positioning long plate 28 needs to be installed.

[0044] As Figure 1 and Figure 9 shown, a rotatable threaded long rod 34 is assembled on the surface of the movable plate 26 through a bearing. The threaded long rod 34 threadedly penetrates through the main body of the detection platform 1 and extends above it. A guide rod two 35 that movably penetrates through the detection platform 1 is assembled on the surface of the movable plate 26. Rotate the threaded long rod 34 so that it moves longitudinally itself, driving the movable plate 26 to move longitudinally, thereby indirectly causing the lever detector 3 to move longitudinally for detection.

[0045] As Figure 5 and Figure 6As shown in the figure, the adjustment component includes a packaging shell 31 with a rotatable connecting rod 30 on its surface. Protrusions may be provided on the surface of the connecting rod 30. The elastic piece 29 is installed on the surface of the packaging shell 31. The lever detector 3 is sleeved on the surface of the connecting rod 30. Grooves corresponding to the protrusions are provided on the surface of the lever detector 3 to prevent the lever detector 3 from rotating due to its own gravity. A rotatable worm 32 is installed inside the packaging shell 31 through a bearing, and one end of it extends to the outside of the packaging shell 31. A worm gear 33 meshing with the worm 32 is fixedly sleeved on the surface of the connecting rod 30. When adjusting the lever detector 3, rotating the worm 32 can drive the worm gear 33 to rotate. At the same time, relying on the characteristic that the worm gear 33 cannot drive the worm 32 to rotate, the detector 3 is prevented from rotating back.

[0046] Before detecting the conductive roller in the present invention, the defect compliance on the surface of the conductive roller needs to be determined first. First, a batch of conductive rollers to be detected are sequentially passed through the machine vision system in a rotating manner for image vision detection. The light source of the machine vision system illuminates the conductive roller and provides uniform and sufficient light to ensure that the surface features of the conductive roller are clearly visible. The image sensor involved in the camera lens of the machine vision system collects the surface image of the conductive roller. The image sensor converts the optical signal into an electrical signal, and after analog-to-digital conversion, the digital image data is transmitted to the image processing unit. The image processing unit analyzes and processes the digital image data to obtain the picture situation of the surface of the conductive roller. If there are no defects on the surface of the conductive roller, it enters the detection process. If there are defects on the surface of the conductive roller, it is automatically removed. The defects that need to be detected on the surface of the conductive roller include scratches, pits, cracks, wear, etc.;

[0047] When conducting the detection of the conductive roller, first move the position of the slider 11 so that the support column 13 moves to a suitable position. Then, place the conductive roller to be detected and without surface defects above the support column 13. Turn on the leveling lamp 36 and observe whether the outer side of the conductive roller coincides with the laser of the leveling lamp 36. If not, it is necessary to rotate the corresponding stud 12 to adjust the height of the support column 13 until it is adjusted to the standard state. Rotate the crank 19 to drive the corresponding threaded rod 16 to rotate, so that the corresponding spur gear 22 rotates through the transmission of the bevel gear 21. Then, through the transmission of the toothed ring 23, all the spur gears 22 meshing with it rotate, indirectly realizing the rotation of all the threaded rods 16. Due to the limitation of the installation groove 24 on the mounting seat 17, it is ensured that the mounting seat 17 moves along the axial direction of the threaded rod 16. At this time, the inclined plate 25 exerts a squeezing effect on the ball 18 and the positioning rod 37, causing the positioning rod 37 to slowly tilt up until the ball 18 abuts against the surface of the conductive roller for clamping and fixing. Rotate the worm 32 to drive the worm wheel 33 to rotate, changing the rotation angle of the connecting rod 30, indirectly causing the end of the lever detector 3 to abut against the surface and / or inner wall of the conductive roller. At this time, the gear inside the lever detector 3 will rotate, causing the tooth column 4 to move longitudinally. The extrusion block 7 will squeeze the scale plate 5 within its path range, causing the positioning block 8 to move into the interior of another card slot 9. At this time, regard the position of the last removed positioning block 8 as the zero point, move the zero scale 10 to align with this position. Then, press all the scale plates 5 into the interior of the protective shell 6. According to the length of the conductive roller, install the moving plate 26 to the appropriate through groove 27 position of the positioning long plate 28 through the elastic piece 29, and the encapsulation shell 31 is also installed at the required through groove 27 position through the elastic piece 29. Rotate the threaded long rod 34 to drive the moving plate 26 to move longitudinally, indirectly driving the lever detector 3 to move longitudinally for detection, thus completing the concentricity detection. It is also possible to move the lever detector 3 down to a specific position and drive the conductive roller to rotate, thereby realizing the roundness detection. When the detection is completed, check the distance between the two ends of the scale plate 5 removed from the protective shell 6 and the zero scale 10, so as to determine whether the conductive roller meets the standard.
