Technical Field

[0001] The present invention relates to the technical field of optical detection, and more particularly to a device for detecting the uniformity of zinc layers on the surfaces of hot-dip galvanized parts. Background Art

[0002] Hot-dip galvanizing refers to metal products treated with a hot-dip galvanizing process, where a layer of zinc is applied to the metal surface to enhance its corrosion resistance and longevity. This process is widely used in a variety of industries, including construction, automotive, and power generation, and is crucial to ensuring product quality and performance.

[0003] Existing optical inspection of hot-dip galvanized parts mainly uses optical principles to perform non-contact measurement and analysis of the uniformity, thickness, defects, etc. of the zinc layer on the surface of hot-dip galvanized parts. Through optical inspection, quality problems on the surface of hot-dip galvanized parts can be discovered efficiently and accurately, providing an important basis for production control and quality assessment.

[0004] However, existing technologies often suffer from incomplete inspection, low efficiency, and excessive manual intervention when performing optical inspection on hot-dip galvanized parts. In particular, multi-sided inspection of hot-dip galvanized parts usually requires multiple adjustments and repositioning, which undoubtedly increases inspection time and reduces overall work efficiency.

[0005] Therefore, in order to solve the above technical problems, the present application proposes a device for detecting the uniformity of the zinc layer on the surface of hot-dip galvanized parts. Summary of the Invention

[0008] A driving disc is mounted on the frame through a driving mechanism. A plurality of light sources are provided on the driving disc. By starting the driving mechanism to rotate the driving disc, different light sources are switched to detect the hot-dip galvanized parts.

[0009] A flipping mechanism is provided on the frame and is transmission-connected to the driving mechanism, and the flipping mechanism is provided with a plurality of card plates through an opening and closing mechanism, and a cavity for inserting the hot-dip galvanized parts is formed between the plurality of card plates. When the driving disk rotates one circle, the driving mechanism drives the flipping mechanism to rotate the hot-dip galvanized parts in the plurality of card plate cavities by ninety degrees, and at the same time, the card plate located above the hot-dip galvanized parts is flipped open through the opening and closing mechanism, thereby realizing the action of the light source irradiating the end of the hot-dip galvanized parts.

[0010] Preferably, the turnover mechanism comprises a cam track arranged on the frame body, and a rotating disc arranged on the frame body and connected with the transmission mechanism, and the clamping plate is slidably arranged in the cam track through the mounting fitting part.

[0011] Preferably, the cam track comprises a circular slide and an arc slide, the middle axis of the rotating disc in the horizontal direction is the intersection of the circular slide and the arc slide, the arc of the circular slide is the same as the arc of the rotating disc, and the arc of the arc slide is larger than the arc of the circular slide.

[0012] Preferably, the mounting fitting part comprises a mounting seat fixed on the clamping plate, and the mounting seat is provided with a connecting piece through a rotating seat, and the connecting piece is slidably arranged in the cam track.

[0013] Preferably, the opening and closing mechanism comprises a plurality of groups of protrusions arranged in a circumferential array on the rotating disc, and a limiting groove is formed between each group of protrusions, and the mounting seat is slidably arranged in the limiting groove.

[0014] Preferably, the opening and closing mechanism further comprises a gear three arranged on the mounting seat, and a rack is arranged on the protrusion and matched with the gear three, when the rotating disc rotates and moves one of the clamping plates from the circular slide to the arc slide through the mounting fitting part, the clamping plate is driven to slide away from the rotating disc along the limiting groove through the arc slide, and the gear three is engaged with the rack.

[0015] Preferably, the surface of the cam track is provided with a limiting pad plate arranged in an arc shape as a whole, when the rotating disc rotates and moves one of the clamping plates from the arc slide to the circular slide through the mounting fitting part, the clamping plate moves along the limiting groove to approach the rotating disc, and the mounting seat surface is abutted with the limiting pad plate surface when the gear three is disengaged from the rack.

[0016] Preferably, the frame body is further provided with a light shielding cover, the light shielding cover is provided with a light transmission opening, and the light shielding cover is attached to the surface of the side of the driving disc where the light source is arranged.

[0017] Preferably, the frame body is provided with a top cover, and the top cover is made of a non-light-transmitting material.

[0018] Preferably, the surfaces of the plurality of clamping plates close to each other are all provided with a reflective strip.

[0019] Compared with the prior art, the present application has the following beneficial effects:

[0020] 1. The driving disc integrates multiple light sources (such as infrared + white light combination light source, green laser light source, etc.), and the driving mechanism controls the rotation of the driving disc to realize automatic switching of different light sources; the light sources adopt a non-uniform arrangement strategy (such as placing the infrared white light combination at the bottom of the driving disc to enhance the iron gray recognition, and setting the green laser at a low angle to highlight the 3D profile), and cooperate with the light transmission port on the light shield cover to ensure that only a single light source works each time; this design can identify different defect types of zinc layer, and significantly improve the accuracy of optical detection.

[0021] 2. Through the linkage of the driving mechanism and the turnover mechanism, after the driving disc rotates one round, the driving disc drives the four clamping plates to rotate 90 degrees synchronously, so that the hot galvanized parts in the rectangular cavity formed by the clamping plates automatically switch the detection surface; this process is completely automated, and the workers only need to place the workpiece for the first time, and then the detection of the four surfaces can be completed in turn, greatly reducing manual intervention and improving work efficiency.

[0022] 3. The turnover mechanism and the opening and closing mechanism work together: when the workpiece rotates to change the surface, the clamping plate above the hot galvanized part is automatically turned over and opened through the meshing of the gear three of the mounting seat and the protruding rack, and at the same time, the arc-shaped slide drives the clamping plate to move away from the workpiece; this action completely exposes the end of the workpiece, avoids the imaging dead angle caused by the shielding of the traditional clamp, and ensures the complete irradiation of the light source to the end.

[0023] 4. The clamping plate has dual functions of mechanical clamping and optical assistance: on the one hand, it stably clamps the workpiece through the rectangular cavity and the edge rubber strip of the reflecting strip to ensure the rotation stability; on the other hand, when it is turned over and opened, the inner reflecting strip reflects the light source to the end of the workpiece to compensate for the light attenuation; at the same time, the limiting pad on the cam track abuts against the mounting seat when the clamping plate is reset to form self-locking, ensuring the clamping reliability and realizing the cooperative optimization of physical avoidance and optical compensation.

DETAILED DESCRIPTION

[0037] As Figures 1-11As shown, the present application provides a hot galvanized part surface zinc layer uniformity detection equipment, including frame body 1, frame body 1 is used for installing each component and provides support, the hot galvanized part surface zinc layer uniformity detection equipment still includes the driving disc 23 installed on the frame body 1 by drive mechanism, the driving disc 23 is provided with a plurality of light sources, by starting the drive mechanism to make the driving disc 23 rotate, to realize switching different light sources to the detection operation of hot galvanized part, frame body 1 still is provided with the light shield cover 4, the light shield cover 4 is provided with the light transmission port, and the light shield cover 4 is attached with the surface of the side of the driving disc 23 where the light source is installed, and a plurality of light sources can be installed at the position and angle on the driving disc 23, for example, the combined light source of infrared plus white light can be installed at the bottom of the driving disc 23, when the driving disc 23 is rotated by the drive mechanism, and the combined light source of infrared plus white light is at the light transmission port position, the combined light source of infrared plus white light is at the bottom of the driving disc 23, the position is slightly lower than the hot galvanized part, the combined light source can effectively enhance the iron gray identification, and the green laser light source can be arranged on the driving disc 23 at a position closer to the center point of the driving disc 23 than the combined light source of infrared plus white light, to irradiate the hot galvanized part at a low angle, which can effectively make the long shadow of the convex 6 part, thereby enhancing the 3D profile visualization; and these light sources cannot be on the same vertical line, so that when the drive mechanism is started, different light sources can be at the light transmission port position, so that the drive mechanism can irradiate the surface of the hot galvanized part by different light sources, thereby improving the optical detection effect of the hot galvanized part and identifying various optical detection problems;

[0038] And the frame body 1 is provided with a top cover 8, the top cover 8 is made of opaque material, and an optical detection camera is arranged at the position close to the frame body 1 of the top cover 8, when the surface of the hot galvanized part is optically detected by the light source, the optical detection camera can be used to take pictures in real time, so that the surface of the hot galvanized part is imaged by different light sources, and various problems are identified;

[0039] And in order to improve the optical detection effect of the zinc layer uniformity of the surface of the hot galvanized part, the hot galvanized part surface zinc layer uniformity detection equipment further comprises a turnover mechanism arranged on the frame body 1 and in transmission connection with the drive mechanism, and the turnover mechanism is provided with a plurality of clamping plates 31 through the opening and closing mechanism, and a cavity for inserting the hot galvanized part is formed between the plurality of clamping plates 31, when the driving disc 23 rotates one revolution, the drive mechanism drives the turnover mechanism to rotate the hot galvanized part in the cavity of the plurality of clamping plates 31 by ninety degrees, and the clamping plate 31 above the hot galvanized part is opened by the opening and closing mechanism, so that the end of the hot galvanized part is irradiated by the light source;

[0040] When optical detection of the uniformity of the zinc layer on the surface of the hot-dip galvanized piece is needed, first, the hot-dip galvanized piece to be detected is placed in the cavities between the plurality of clamping plates 31, and the other side of the hot-dip galvanized piece is lapped on the cushion block 5 arranged on the frame body 1, at this time, the placement of the hot-dip galvanized piece is completed, then the light source on the driving disc 23 is started, the surface of the hot-dip galvanized piece is irradiated by the light source, after the irradiation of the light source is completed, the driving mechanism is controlled to rotate the driving disc 23, the light source is switched, and the surface of the hot-dip galvanized piece is irradiated and imaged by the optical camera again, so as to realize the optical detection of the uniformity of the zinc layer on the surface of the hot-dip galvanized piece;

[0041] When the driving disc 23 rotates one round, that is, the light sources on the driving disc 23 complete the irradiation of the hot-dip galvanized piece, the driving disc 23 is rotated again by the driving mechanism, at this time, the driving mechanism also rotates the hot-dip galvanized piece in the cavity by ninety degrees through the turnover mechanism, so that the hot-dip galvanized piece inserted in the cavity is rotated by ninety degrees, at this time, the hot-dip galvanized piece is replaced, and the other side of the hot-dip galvanized piece is optically detected by the light sources again, the hot-dip galvanized piece clamped by the plurality of clamping plates 31 can be automatically replaced after all the light sources pass through the light transmission port, so that the plurality of outer surfaces of the hot-dip galvanized piece can be automatically detected without manual control, only the hot-dip galvanized piece needs to be inserted into the middle cavity of the plurality of clamping plates 31 by the staff, and the overall operation is relatively convenient;

[0042] It should be noted that the clamping plates 31 are preferably four groups, and the cavities between the four groups of clamping plates 31 form a rectangle, so that when the hot-dip galvanized piece is inserted into the rectangular cavity, the hot-dip galvanized piece is rotated through the rectangular cavity when the four clamping plates 31 are rotated under the drive of the turnover mechanism, so that the hot-dip galvanized piece is replaced;

[0043] When the hot-dip galvanized part is changed, the clamping plate 31 above the hot-dip galvanized part is turned over and opened through the opening and closing mechanism, the end of the hot-dip galvanized part is irradiated by the light source, and the reflective strips are arranged on the surfaces of the clamping plates 31, so that after the detection of the surface of the hot-dip galvanized part is completed, the hot-dip galvanized part can be automatically changed, the clamping plate 31 above the hot-dip galvanized part can be automatically turned over and opened, the end of the hot-dip galvanized part is not blocked and exposed, the blocking is prevented when the light source is irradiated, the imaging is not affected, the reflective strips arranged on the clamping plate 31 can reflect light, the defect detection rate and the measurement accuracy are significantly improved, the clamping plate 31 can drive the hot-dip galvanized part to rotate and change the surface in the rectangular cavity after the detection of the surface of the hot-dip galvanized part by all light sources is completed, the clamping plate 31 above the hot-dip galvanized part can be automatically turned over and opened when the surface is changed, the end of the hot-dip galvanized part is exposed, the blocking is prevented, and the integrity of the optical detection is improved. Since complete optical detection is required, the end of the hot-dip galvanized part cannot be blocked, the turned clamping plate 31 reflects light, the problem that the irradiation of the end of the hot-dip galvanized part by the light source is not clear due to the distance effect is prevented, the irradiation effect of the optical detection of the end of the hot-dip galvanized part by the light source is improved, the clamping plate 31 has multiple synergistic effects and achieves multiple effects, and has good practicability.

[0044] In an embodiment of the present application, the turning mechanism includes a cam track 32 arranged on the frame 1, and a rotating disc 3 rotatably arranged on the frame 1 and connected with the transmission mechanism, and the clamping plate 31 is slidably arranged in the cam track 32 through the mounting and fitting part, and the rotating disc 3 is driven to rotate by the driving mechanism after one cycle of rotation of the driving disc 23.

[0045] In an embodiment of the present application, the mounting and fitting part includes a mounting seat 33 fixed to the clamping plate 31, and the mounting seat 33 is provided with a connecting piece 34 through a rotating seat 35, and the connecting piece 34 is slidably arranged in the cam track 32, the opening and closing mechanism includes a plurality of protrusions 6 arranged in a circumferential array on the rotating disc 3, a limiting groove 61 is formed between each group of protrusions 6, and the mounting seat 33 is slidably arranged in the limiting groove 61, and when the rotating disc 3 is driven to rotate by the driving mechanism, the four groups of clamping plates 31 on the rotating disc 3 rotate together, and the four groups of clamping plates 31 slide along the cam track 32 through the mounting and fitting part, and the connecting piece 34 is a universal shaft, which is a product and will not be described in detail.

[0046] The cam track 32 comprises a circular slide and an arc slide, the middle axis of the rotating disc 3 in horizontal direction is the intersection of the circular slide and the arc slide, the arc of the circular slide is the same as the arc of the rotating disc 3, and the arc of the arc slide is larger than the arc of the circular slide. When the rotating disc 3 rotates, because the arc of the circular slide is the same as the arc of the rotating disc 3, one of the clamping plates 31 enters the arc slide from the circular slide under the driving of the installation fitting part, the arc of the arc slide is larger, and the clamping plate 31 starts to move away from the rotating disc 3 in the limiting groove 61 under the pulling of the sliding fitting part and the arc slide, so that the clamping plate 31 gradually moves away from the hot galvanizing part, and the clamping plate 31 above the hot galvanizing part moves along the arc slide to the circular slide under the pulling of the protrusion 6, so that the clamping plate 31 moves along the limiting groove 61 to the rotating disc 3 under the pulling of the arc slide, until the installation fitting part on the clamping plate 31 enters the circular slide, at this time, the position change of the adjacent two clamping plates 31 is completed, and the rotation of the hot galvanizing part is also completed, so that the other side of the hot galvanizing part faces upward to perform subsequent optical detection. When the hot galvanizing part rotates, the clamping plate 31 above the hot galvanizing part always moves away from the rotating disc 3, that is, moves away from the hot galvanizing part, so that the clamping plate 31 at the position above the hot galvanizing part can prevent the end of the hot galvanizing part from being shielded, and the integrity of the light source irradiating the hot galvanizing part is improved.

[0047] Because the arc of the circular slide is the same as the arc of the rotating disc 3, when the rotating disc 3 rotates, the rotating arc of the installation fitting part on the circular slide does not change when it is not switched to the arc slide, and the rotating arc of the rotating disc 3 is the rotating arc of the installation fitting part, so that the position of the two adjacent clamping plates 31 does not change when the hot galvanizing part rotates, so that the hot galvanizing part can rotate smoothly, and the edge of the reflective strip of the clamping plate 31 can be provided with a rubber strip to increase the friction with the surface of the hot galvanizing part, so that the stability of the hot galvanizing part during rotation is further improved when the plurality of clamping plates 31 rotates as a whole.

[0048] It should be noted that the arc of the arc slide should not be too large. When the rotating disc 3 rotates, the arc does not cause the clamping between the protrusion 6 and the mounting seat 33 when the protrusion 6 pushes the mounting seat 33 to move away from the hot galvanizing part along the arc slide, and the arc does not need to be too large. Only a certain gap between the clamping plate 31 above the hot galvanizing part and the hot galvanizing part is needed, which is used to reserve space when the opening and closing mechanism flips the clamping plate 31. Therefore, the arc of the arc slide does not need to be too large, and it is appropriate. The arc can be obtained by simple experiment, and it is not a fixed value, which is not described in detail.

[0049] In still another embodiment of the present application, the opening and closing mechanism further comprises a gear three 63 arranged on the mounting seat 33, a gear rack 62 is arranged on the protrusion 6, the gear rack 62 is adapted to the gear shape of the gear three 63, when the rotating disc 3 rotates and one of the clamping plates 31 is moved from the circular slide to the arc slide by the mounting fitting part, the clamping plate 31 is driven to slide along the limiting groove 61 away from the rotating disc 3 by the arc slide, and the gear three 63 is engaged with the gear rack 62, when one of the clamping plates 31 is moved along the limiting groove 61 away from the hot galvanized plate, the gear three 63 is engaged with the gear rack 62, the gear rotates, and the clamping plate 31 is turned over by the mounting seat 33 until the clamping plate 31 moves upward to the maximum stroke, the clamping plate 31 is turned over to the maximum angle, at this time, the reflective strip inside the clamping plate 31 leaks out, and the shielding of the surface of the hot galvanized part is removed, which facilitates the light source to irradiate and image the whole hot galvanized part, improves the condensing effect, improves the irradiation effect of the end part of the hot galvanized part far away from the light source, prevents the appearance of the irradiation dead angle from affecting the detection result, and the four clamping plates 31 which can be independently turned over and opened can not only place the hot galvanized part, but also serve as a detection table for optical detection of the hot galvanized part, and can automatically open the clamping plate 31 above the hot galvanized part during optical detection of the hot galvanized part, prevent shielding, and do not need secondary operation, which has better use effect.

[0050] It should be noted that the reflective strip can be designed as concave to further improve the condensing effect, and the specific design can be selected according to the actual situation.

[0051] It needs to be noted that the limiting pad plate 7 is arranged on the surface of the cam track 32 in an overall arc shape, when the rotating disc 3 rotates and one of the clamping plates 31 is moved from the arc-shaped slide to the circular slide through the installation fitting part, the clamping plate 31 is moved along the limiting groove 61 to approach the rotating disc 3, and the gear three 63 is separated from the rack 62, the surface of the mounting seat 33 abuts against the surface of the limiting pad plate 7, when the clamping plate 31 is rotated from the arc-shaped slide to the circular slide through the installation fitting part, the gear three 63 is reversely rotated through the action of the rack 62 and the gear three 63, when the clamping plate 31 in the upper part moves towards the circular slide, the angle starts to recover, and gradually approaches the hot-dip galvanized part, in this process, the mounting seat 33 also recovers the initial angle, after the clamping plate 31 and the mounting seat 33 recover the initial angle, the rack 62 and the gear three 63 are separated, at this time, the mounting seat 33 and the clamping plate 31 will not rotate again, but will continue to move along the limiting groove 61 to the direction of the hot-dip galvanized plate, until moving to the maximum stroke, the mounting seat 33 abuts against the surface of the limiting pad plate 7, at this time, the clamping plate 31 rotates next time and rotates to the lower part of the hot-dip galvanized part, because the circular slide pulls the installation fitting part, the clamping plate 31 located below the hot-dip galvanized part will not sink, and because the limiting pad plate 7 abuts against the mounting seat 33, the mounting seat 33 will not rotate at this time, the limiting pad plate 7 forms self-locking to the mounting seat 33, prevents displacement when the hot-dip galvanized part is supported, the limiting pad plate 7 is simple and convenient in design, without additional structure, and the installation cost is greatly reduced.

[0052] In still another embodiment of the present application, the driving mechanism comprises a motor 2 mounted on the frame 1, the motor 2 is used to drive the driving disc 23 to rotate, so as to switch the light source, and the driving mechanism further comprises a driving shaft 27 fixedly connected to the driving disc 23 and an intermittent rotating disc 24 rotatably mounted on the frame 1, the intermittent rotating disc 24 is provided with a gear one 21 and a gear two 22 rotatably mounted on the frame 1, the gear two 22 is further provided with a synchronous wheel 25, the synchronous wheel 25 is connected to the shaft of the rotating disc 3 through a synchronous belt 26 away from the side end of the gear two 22, when the intermittent rotating disc 24 rotates, the rotating disc 3 can be rotated through the gear one 21, the gear two 22, the synchronous wheel 25 and the synchronous belt 26, so as to rotate the plurality of clamping plates 31;

[0053] It needs to be explained that the position of the light source on the driving disc 23 needs to be considered, for example, there are five light sources, then the motor 2 is started four times, all the light sources irradiate a surface of the hot galvanized part completely, at this time the motor 2 is started again, the hot galvanized part needs to be turned over, so the five light sources need to be arranged in a circular array, but it needs to be ensured that there are not two light sources at the position of the light transmission port at the same time, therefore, if the number of light sources is equal to the number of the driving disc 23, two light sources will be at the position of the light transmission port at the same time, then the following way is needed to arrange the light sources: the light sources do not need to be arranged in a circular array on the driving disc 23, but can be arranged randomly, only the condition that there are not two light sources at the position of the light transmission port at the same time is needed, here only the amplitude of the motor 2 each time is needed to be adjusted, and the existing technology is not described in detail, but no matter how the position of the light source is arranged, after the light source irradiates a surface of the hot galvanized part completely, the next time the motor 2 is started, the driving disc 23 needs to be rotated to make the first light source face the light transmission port.

[0054] It also needs to be explained that after the driving disc 23 rotates one circle, that is, under the driving of the motor 2, the first light source faces the light transmission port again, the driving shaft 27 rotates the intermittent rotating disc 24 by being inserted into the missing slot 28, and the rotating disc 3 is rotated by the gear one 21, the gear two 22, the synchronous wheel 25 and the synchronous belt 26, here it is ensured that the rotating disc 3 rotates ninety degrees each time, which can be realized by adjusting the radius ratio of the gear one 21 and the gear two 22, and the result can be obtained by simple calculation, and the existing technology is not described in detail.

[0055] The above only describes some exemplary embodiments of the present application in a descriptive manner, it is needless to say that the described embodiments can be modified in various ways without departing from the spirit and scope of the present application for those skilled in the art. Therefore, the above drawings and description are illustrative in nature and should not be understood as limiting the scope of protection of the claims of the present application.
