Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of visual detection, and in particular to an environment-friendly plate edge defect visual detection device for decoration. BACKGROUND

[0002] The existing visual detection technology collects images by industrial cameras, lenses and the like, and combines machine vision algorithm processing and analysis to identify product size deviation, surface defects and the like. The detection accuracy is improved by a deep learning model, and the model is adapted to various scenes to realize automatic and high-speed detection and replace manual work, and is widely used in electronic and automobile manufacturing industries.

[0003] Plate visual detection is to collect plate edge images by a high-definition camera, and to analyze the images by an image processing algorithm to quickly identify defects such as glue deficiency, glue overflow, cracking and burr, realize automatic detection, improve efficiency and accuracy, reduce human error, and adapt to high-speed detection requirements of a flow line. The position of the inspection camera during detection is very critical. Traditionally, the camera is arranged in the horizontal direction of the plate, and the detection surface is the edge side. This detection orientation cannot detect the bonding state between the upper and lower ends of the edge and the plate, so that defects such as glue deficiency and cracking cannot be detected. Therefore, multiple visual angle detection camera assemblies need to be provided, which undoubtedly increases the detection cost burden. Moreover, the shooting range of the camera assembly is limited, and further camera assemblies need to be added to face the long plate edge. Moreover, since the plate edge is not only one side, camera assemblies on the other side of the plate need to be added accordingly. The arrangement of multiple camera assemblies will inevitably increase the maintenance cost.

[0021] Specifically, as shown in Figure 1 And Figure 4As shown, the driving mechanism comprises a sliding frame 13, which is similar in structure to a trapezoidal structure with a short side opening, the inclined side of which can contact the connecting block 20 to cause the connecting block 20 to deflect, the connecting frame 17 is connected with a sliding frame 14, the sliding frame 13 is slidably connected to the upper and lower edges of the sliding frame 14, the sliding frame 14 is a square box structure, the sliding frame 13 is slidably connected to the sliding frame 14, the sliding frame 13 is rotatably connected with a traction strip 12 through the connecting column 11, the connecting frame 17 is rotatably connected with a bevel gear two 10, the bevel gear two 10 and the bevel gear one 8 are in meshing relationship, the other end of the traction strip 12 is rotatably connected to the connecting column 11 of the bevel gear two 10, and the connecting column 11 is provided with two, and the two connecting columns 11 are vertically connected to the sliding frame 13 and the bevel gear two 10 respectively.

[0022] Specifically, as shown in Figure 4 and Figure 5 As shown, the sliding frame 13 is connected with a symmetrical rod 19, the symmetrical rod 19 is slidably connected with a lifting inclined block 18, two inclined surfaces are formed on the lifting inclined block 18, and the two inclined surfaces are just corresponding to the two inclined plates 15, so that when the lifting inclined block 18 contacts the inclined plate 15, the inclined plate 15 can push the lifting inclined block 18 to slide on the symmetrical rod 19, the lifting inclined block 18 is connected with a hinged frame 30, the hinged frame 30 is arranged on the side of the lifting inclined block 18 facing the plate, and the connecting block 20 is connected to the hinged frame 30 through a torsional spring 31, the function of the torsional spring 31 is to drive the connecting block 20 to be horizontally arranged, and when the connecting block 20 contacts the inclined surface on the sliding frame 13, the connecting block 20 deflects at this time.

[0023] Specifically, as shown in Figure 4 As shown, the lifting inclined block 18 is provided with an inclined surface, the sliding frame 14 is connected with an inclined plate 15, the inclined plate 15 is provided with two structures, the line between the two structures of the inclined plate 15 is an inclined line, and the inclined surface on the lifting inclined block 18 and the two inclined plates 15 can cooperate with each other.

[0024] Specifically, as shown in Figure 4 As shown, the sliding frame 13 is connected with a connecting strip 22, the connecting strip 22 is rotatably connected with a pushing rod 26 through a shaft one 23, the lifting inclined block 18 is provided with a pushing groove 25, one end of the pushing rod 26 is arranged in the pushing groove 25, when the pushing rod 26 deflects, the lifting inclined block 18 can be driven to move along the symmetrical rod 19, the pushing rod 26 is rotatably connected with a spring 28 through a shaft three 27, the other end of the spring 28 is rotatably connected to one side of the pushing rod 26 through a shaft two 24, the spring 28 is always in a stretched state, and the spring 28 can drive the pushing rod 26 to be in an upward deflection or downward deflection state.

[0025] Specifically, as shown in Figure 4As shown, the sliding frame 13 is provided with a through groove 29, and the actuating rod 26 is arranged on the through groove 29. The through groove 29 can limit the actuating rod 26, improve the stability of the structure when the actuating rod 26 is deflected, and avoid the problem of the actuating rod 26 deviating.

[0026] Specifically, as shown in Figure 3 and Figure 4 The upper and lower surfaces of the sliding frame 13 are provided with inclined surfaces, and the side of the connecting block 20 is matched with the inclined surface of the sliding frame 13. Through the cooperation between the inclined surfaces, the camera assembly 21 can detect the edge of the plate at the best detection angle, improve the detection accuracy, avoid the problem of missed detection, and the detection device only needs to be provided with one set of camera assembly 21, which can greatly reduce the maintenance cost and improve the resource utilization rate.

[0027] In summary, the environmental protection plate edge defect visual detection device for decoration provided in the embodiment can place the plate on the fixing frame 2 when the edge of the environmental protection plate for decoration needs to be detected. By rotating the clamping piece 3, one end of the clamping piece 3 is clamped on the surface of the plate, so that the plate is fixed on the fixing frame 2. When fixed, it is necessary to ensure that one end of the clamping piece 3 abuts against the middle position of the plate.

[0028] Then start the rotating motor 7, drive the bevel gear one 8 to rotate, and drive the bevel gear two 10 to rotate due to the meshing between one side of the bevel gear one 8 and the bevel gear two 10. The traction strip 12 can drive the sliding frame 13 to move horizontally and reciprocally on the sliding frame 14, and synchronously drive the camera assembly 21 to move reciprocally, so that the detection can cover the complete edge of the plate on one side.

[0029] When the sliding frame 13 moves to contact the inclined plate 15, the inclined surface on the inclined plate 15 can abut against the inclined surface on the lifting inclined block 18. With the movement of the lifting inclined block 18, the inclined plate 15 can push the lifting inclined block 18 to move, so that the lifting inclined block 18 slides along the symmetrical rod 19. The actuating groove 25 on one side of the lifting inclined block 18 drives the actuating rod 26 to deflect. At this time, the spring 28 structure is further stretched. When the lifting inclined block 18 moves to the middle position of the symmetrical rod 19 and continues to move, the actuating rod 26 can be pulled by the spring 28 structure, so that the actuating rod 26 continues to deflect once, thereby driving the lifting inclined block 18 to move to one end of the symmetrical rod 19. At this time, the lifting inclined block 18 is separated from the inclined plate 15.

[0030] Due to the structure of the spring 28, the lever 26 is inclined upward or downward without external force, and one end of the lever 26 is clamped in the dial slot 25, so that the lifting inclined block 18 can be stably arranged at the upper end or the lower end of the symmetrical rod 19. When the lifting inclined block 18 is arranged at the upper end or the lower end of the symmetrical rod 19, the connecting block 20 connected to one side of the lifting inclined block 18 can contact the inclined surface on the sliding frame 13, so that the connecting block 20 is in an inclined state, that is, the connecting block 20 can switch between the inclined downward state and the inclined upward state. When the connecting block 20 is in the inclined downward state or the inclined upward state, the camera assembly 21 connected to one end of the connecting block 20 can detect the defects of the plate edge in the inclined downward state or the inclined upward state.

[0031] Therefore, with the rotation of the bevel gear 10, the camera assembly 21 can detect the plate edge in the inclined downward state, and then detect the plate edge in the inclined upward state. The above two processes correspond to the reciprocating process of the sliding frame 13.

[0032] When the bevel gear 8 rotates, the rotating knob 9 rotates, and when the rotating knob 9 contacts the dial piece 5, the dial piece 5 rotates with the missing gear 4. At this time, the missing gear 4 can be meshed with the tooth groove 32 on the bevel gear 8, so that the missing gear 4 can be rotated synchronously with the bevel gear 8, so that the plate can be turned over. When the tooth groove 32 is not meshed with the missing gear 4, the bevel gear 8 rotates, and the missing gear 4 does not rotate. That is, when the bevel gear 8 rotates one circle, the missing gear 4 can rotate half a circle, so that the plate can be turned over, and the other side of the plate edge can be displayed in the detection range of the camera assembly 21.

[0033] After the rotating motor 7 is started, the plate is intermittently turned over, and the camera assembly 21 is continuously reciprocated horizontally. That is, when the camera assembly 21 detects, the plate is also turned over, and the camera assembly 21 moves to one end of the plate. Since the camera assembly 21 has a detection range, the turning over of the plate does not affect the detection. On the contrary, the turning over of the plate can make the plate edge at various angles appear in the detection area of the camera assembly 21, so that the detection accuracy is improved.

[0034] The above description of the embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
