Description

Technical Field

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

[0002] Electrogalvanized conductive rollers play a very important role in the electrogalvanizing production process. They must have good conductivity to ensure that the current can be transmitted stably and evenly to ensure the normal progress of the electroplating process. Poor conductivity of the conductive roller will lead to uneven current distribution, which in turn makes the coating thickness inconsistent and affects product quality. Hollow cylindrical conductive rollers are also a commonly used conductive roller. A wire channel is formed inside and a power cord can be installed. It can optimize the current inflow path and make the current more evenly distributed when it is diverted from the middle to the two ends, greatly avoiding the occurrence of burnt edges.

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

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

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

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

[0036] The detection platform 1 is equipped with a lever detector 3 for contacting the surface and / or interior of the conductive roller. The lever detector 3 is a prior art and will not be described in detail 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 a traditional lever meter, when the lever detector 3 moves out from the interior of the conductive roller, it is still possible to determine whether the conductive roller is standard by checking the display mechanism;

[0037] like Figure 5-Figure 7 As shown, the display mechanism includes a slidable tooth column 4 meshing with the internal gear of the lever detector 3. The side of the lever detector 3 is equipped with a protective shell 6 with a plurality of movable scale plates 5 on the surface. In the initial state, the scale plates 5 are located inside the protective shell 6. When the scale plates 5 protrude from the surface of the protective shell 6, it means that there is an error in the standard value at a certain position inside the conductive roller. A triangular extrusion block 7 is provided on the side of the tooth column 4 opposite to the teeth, which is used to press against the surface of the scale plate 5 and move it. As the tooth column 4 moves, the extrusion block 7 will move. Figure 6-Figure 8 As shown, the sunken position of the side of the scale plate 5 is installed with a hemispherical positioning block 8 at one 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 on the outside of the sunken position. The lever detector 3 has two slots 9 corresponding to the position of the positioning block 8 along the moving direction of the scale plate 5. The positioning block 8 is against the inside of one of the slots 9. When the scale plate 5 moves, the slot 9 squeezes the positioning block 8. At this time, the spring is in a compressed state until the positioning block 8 moves to the position of the next slot 9. At this time, the scale plate 5 protrudes from the surface of the protective shell 6. A movable zero scale 10 is provided on the side of the lever detector 3. The zero scale 10 is fixed by friction. The position of the zero scale 10 needs to be adjusted before each detection, and reading is facilitated by zeroing.

[0038] First, it is necessary to calibrate the lever detector 3 to zero, and place the detection end of the lever detector 3 against the surface of the conductive roller. At this time, the gear inside the lever detector 3 will rotate, causing the tooth column 4 to move longitudinally, and the extrusion block 7 will squeeze the scale plate 5 within its path range, causing the positioning block 8 to move to the inside of another slot 9. At this time, the position of the last positioning block 8 moved out 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 inside of the protective shell 6. When the lever detector 3 is moving, the rotation of its detection end can cause the tooth column 4 to move, thereby moving the scale plate 5 to the outside of the protective shell 6. The inspector can determine whether the roundness and concentricity of the conductive roller are within the allowable error range by reading the scale plate 5.

[0039] like Figure 2-Figure 3As shown, the leveling mechanism includes at least three sliders 11 arranged in a circular array, and need to be arranged in a circular shape 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. 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 frustum-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 conductive roller is supported by the three support columns 13 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 as 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 is installed inside the track groove 14 to limit the slider 11. 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 inspector 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 opened on the surface of the detection platform 1 corresponding to the position of 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 produce displacement. A rotatable circular shaft 20 is installed at the position corresponding to the three threaded rods 16 inside the detection platform 1. 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. The three spur gears 22 are connected in transmission through a gear ring 23. The surface of the threaded rod 16 is threaded with a mounting seat 17 whose side wall fits the inner wall of the mounting groove 24. A positioning rod 37 with a ball 18 at 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 inside of the mounting groove 24, and the ball 18 rests on the surface of the inclined plate 25. One end of one of the threaded rods 16 is installed with a crank 19 for driving it to rotate.

[0042] Turning the crank 19 drives the corresponding threaded rod 16 to rotate, thereby rotating the corresponding spur gear 22 through the transmission of the bevel gear 21, and then rotating all the spur gears 22 meshing with it through the transmission of the gear ring 23, thereby indirectly realizing the rotation of all the threaded rods 16. Since the mounting groove 24 limits the mounting seat 17, the mounting seat 17 is guaranteed to move axially along the threaded rod 16. At this time, the inclined plate 25 has an extrusion effect on the ball 18 and the positioning rod 37, causing the positioning rod 37 to slowly tilt until the ball 18 rests on the surface of the conductive roller for clamping and fixing. The ball 18 will not affect the rotation of the conductive roller. During this process, the torsion spring is in a compressed state, so the conductive roller can be clamped and fixed by the elastic force. At the same time, when removing the clamping force, it is only necessary to rotate the crank 19 in the opposite direction.

[0043] like Figure 1 and Figure 9 As shown, the lifting mechanism includes a movable plate 26 that can be lifted and lowered. A positioning long plate 28 with a plurality of through grooves 27 on the surface is installed on the surface of the movable plate 26. The positioning long plate 28 can be set to a multi-section type and can be selectively spliced and extended when in use. An adjustment component for adjusting the rotation angle of the lever detector 3 is installed on the surface of the positioning long plate 28. The adjustment component is used to make the detection end of the lever detector 3 rest against the surface of the conductive roller. For conductive rollers of different diameters, the adjustment component and the surface of the movable plate 26 are both stuck in the inside of the through groove 27 through an L-shaped spring clip 29. At least two groups of spring clips 29 are set on the movable plate 26, and two positioning long plates 28 are installed to detect the inner wall and outer side of the conductive roller respectively. If it is a shaft-type conductive roller, only one positioning long plate 28 needs to be installed.

[0044] like Figure 1 and Figure 9 As 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 is threaded through the detection platform 1 body and extends above it. The surface of the movable plate 26 is equipped with a guide rod 2 35 that is movable through the detection platform 1. The threaded long rod 34 is rotated to cause itself to move longitudinally, driving the movable plate 26 to move longitudinally, thereby indirectly causing the lever detector 3 to move longitudinally for detection.

[0045] like Figure 5 and Figure 6As shown, the adjustment component includes an encapsulating shell 31 with a rotatable connecting rod 30 on the surface. The surface of the connecting rod 30 may be provided with a protrusion. The spring 29 is installed on the surface of the encapsulating shell 31. The lever detector 3 is sleeved on the surface of the connecting rod 30. The surface of the lever detector 3 is provided with a groove corresponding to the protrusion to prevent the lever detector 3 from rotating due to its own gravity. A rotatable worm 32 is installed inside the encapsulating shell 31 through a bearing, and one end of the worm 32 extends to the outside of the encapsulating shell 31. A worm wheel 33 engaged with the worm 32 is fixedly sleeved on the surface of the connecting rod 30. When the lever detector 3 is adjusted, rotating the worm 32 can drive the worm wheel 33 to rotate. At the same time, the worm wheel 33 cannot drive the worm 32 to rotate, which prevents the detector 3 from rotating.

[0046] Before inspecting the conductive roller, the present invention first determines the defect compliance of the conductive roller surface. First, batches of conductive rollers to be inspected are rotated and sequentially passed through a machine vision system for image visual inspection. The light source of the machine vision system is used to illuminate the conductive rollers and provide uniform and sufficient light to ensure that the surface features of the conductive rollers 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 light signal into an electrical signal. After analog-to-digital conversion, the digital image data is transmitted to an image processing unit. The image processing unit analyzes and processes the digital image data to obtain a picture of the conductive roller surface. If the conductive roller surface is defect-free, it enters the inspection process. If the conductive roller surface has defects, it is automatically rejected. The defects that need to be inspected on the conductive roller surface include scratches, pits, cracks, wear, etc.

[0047] When testing the conductive roller, first move the position of the slider 11 so that the support column 13 moves to the appropriate position, then place the conductive roller that needs to be tested and has no surface defects on the top of the support column 13, turn on the leveling light 36 to observe whether the outer side of the conductive roller coincides with the laser of the leveling light 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, and turn the crank 19 to drive the corresponding threaded rod 16 to rotate, so that the corresponding spur gear 22 is driven by the bevel gear 21. The worm 32 rotates, and then the gear ring 23 drives all the spur gears 22 meshing with it to rotate, thereby indirectly realizing the rotation of all the threaded rods 16. Since the mounting groove 24 limits the mounting seat 17, the mounting seat 17 is guaranteed to move along the axial direction of the threaded rod 16. At this time, the inclined plate 25 has an extrusion effect on the ball 18 and the positioning rod 37, so that the positioning rod 37 slowly rises until the ball 18 rests on the surface of the conductive roller for clamping and fixing. The worm 32 is rotated to drive the worm wheel 33 to rotate, thereby changing the rotation angle of the connecting rod 30, thereby indirectly realizing the rotation of the connecting rod 30. The end of the lever detector 3 is pressed 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 squeezing block 7 will squeeze the scale plate 5 within its path range, causing the positioning block 8 to move into another slot 9. At this time, the position of the positioning block 8 that was last removed 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 interior of the protective shell 6. According to the length of the conductive roller, the movable plate 26 is installed in the appropriate through-slot 27 position of the positioning long plate 28 through the spring plate 29. The packaging shell 31 is also installed in the required through-slot 27 position through the spring plate 29. The threaded long rod 34 is rotated to drive the movable plate 26 to move longitudinally, indirectly driving the longitudinal movement detection of the lever detector 3 to complete the concentricity test. The lever detector 3 can also be moved down to a specific position to drive the conductive roller to rotate, thereby realizing the roundness test. When the test is completed, the distance between the two end scale plates 5 removed from the protective shell 6 and the zero scale 10 is checked to determine whether the conductive roller meets the standard.
