Description

Technical Field

[0001] This invention relates to the field of visual inspection technology, specifically to a glass cover plate defect detection device based on visual recognition. Background Technology

[0002] Machine vision, in essence, uses machines to replace human eyes for measurement and judgment. A machine vision system uses machine vision products (image acquisition devices, either CMOS or CCD) to convert the captured target into image signals, which are then transmitted to a dedicated image processing system. Based on pixel distribution and information such as brightness and color, these signals are converted into digital signals. The image system performs various calculations on these signals to extract the target's features, and then controls the on-site equipment based on the judgment results. However, existing machine vision measurement devices cannot perform flexible operations such as translation and rotation, which is a significant limitation. Furthermore, when inspecting the dimensions of some glass photographs, the camera position of the vision machine needs constant adjustment, making flexible operation a crucial factor.

[0003] A search revealed Chinese patent CN212674746U, which discloses a visual inspection device for glass photographs. This device integrates an industrial camera and a light source to form a machine vision system for inspecting the surface of glass photographs, detecting color differences and blemishes. It connects to a computer and a control center, which operates three motors to adjust the position of the industrial camera to inspect various locations on the glass photograph. However, several problems still exist:

[0004] 1. Visual inspection can only be performed on one potential defective area of ​​a glass product at a time, resulting in low inspection efficiency;

[0005] 2. It is impossible to effectively limit and fix the glass products. During the inspection process, the vibration of the motor may cause the position of the glass products to change, which will have a great impact on the inspection results.

[0006] 3. Glassware should only be placed flat on the table. Since visual inspection of glass defects is based on the principle of diffuse reflection, there is a certain probability that the visual camera will miss the defects when the glassware is placed flat. Summary of the Invention

[0021] Beneficial effects

[0022] Compared with the prior art, the present invention provides a glass cover plate defect detection device based on visual recognition, which has the following beneficial effects:

[0023] 1. The present invention uses the limiting part on the fixed base plate in the glass cover plate fixing mechanism to initially limit and fix the glass cover plate, and the fixing plate is provided with multiple sets of fixed base plates. The visual inspection mechanism can inspect multiple sets of glass cover plates at one time, which improves the inspection efficiency.

[0024] 2. This invention uses a suction cup on a fixed base plate in conjunction with an external negative pressure device to adsorb the glass cover plate by the negative pressure generated by the suction cup, which improves the firmness of the glass cover plate when the fixed plate rotates and prevents the glass cover plate from falling off during precision testing.

[0025] 3. This invention allows the fixed glass cover to rotate to any angle through the cooperation of the fixed base plate and the damping bearing. After the glass cover is fixed and attached by the suction cup, the fixed base plate is rotated and then illuminated by the light strip. The defects in the glass cover will undergo diffuse reflection, which will expose the defects to the visual inspection mechanism very clearly.

[0026] 4. This invention enables the vision inspection mechanism to move laterally via the second drive motor, allowing it to move directly above the fixed plate. This allows for the inspection of multiple sets of glass covers at once, detecting any abnormal glass covers. The vision inspection mechanism is then moved laterally to the stroke of the fixed base plate's rotation, and then driven downwards by the longitudinal drive mechanism to close the distance, thus achieving precise inspection of the glass covers. This improves efficiency, and the rotation of the fixed base plate further enhances the accuracy of the inspection.

[0027] 5. The present invention enables the visual inspection mechanism to move smoothly laterally via the rollers at the bottom of the slide, and the limiting part on the side of the rubber pad can prevent the rubber pad from excessively squeezing the glass cover plate, causing the glass cover plate to deform and resulting in abnormal inspection.

[0038] Reference Figures 1-6 A visual recognition-based glass cover defect detection device includes a substrate body 1, a rotatable glass cover fixing mechanism 2 disposed on the top of the substrate body 1, a driving mechanism 3 disposed on the substrate body 1 to drive the glass cover fixing mechanism 2 to rotate, an adsorption mechanism 4 disposed at the upper end of the substrate body 1 to generate negative pressure in the glass cover fixing mechanism 2, a central lighting mechanism 5 disposed in the middle of the glass cover fixing mechanism 2, a transverse driving mechanism 6 disposed on the side of the substrate body 1, a longitudinal driving mechanism 7 disposed at the upper end of the transverse driving mechanism 6, and a visual inspection mechanism 8 disposed between the longitudinal driving mechanisms 7.

[0039] In particular, in this invention, the glass cover plate fixing mechanism 2 includes a fixing plate 201 and a central fixing ring 202. The fixing plate 201 is rotatably mounted on the substrate body 1, and the central fixing ring 202 is welded and fixed to the upper end of the substrate body 1. A bearing 203 is fixedly connected to the outside of the central fixing ring 202, and the outer ring of the bearing 203 is fixedly connected to the inner side of the fixing plate 201. Through the cooperation of the central fixing ring 202, the bearing 203 and the fixing plate 201, the fixing plate 201 can rotate above the substrate body 1.

[0040] It should be noted that the upper outer side of the central fixing ring 202 is provided with six sets of through grooves 204, which are arranged in a ring array. The inner wall of the through grooves 204 is fitted with a damping bearing 205. The inner ring of the damping bearing 205 is fixedly connected to a fixing rod 206. A fixing base plate 207 is welded and fixed between two sets of fixing rods 206. The upper end of the fixing base plate 207 is integrally formed with a limiting part 208. A rubber pad 209 is bonded and fixed to the inner side of the limiting part 208. The damping bearing 205 allows the fixing base plate 207 to be rotated to any angle and locked. The rubber pad 209 on the inner side of the limiting part 208 can initially limit and fix the glass cover.

[0041] In particular, in this invention, the upper end of the substrate body 1 is provided with two sets of symmetrically arranged grooves 101 and 102, and the grooves 101 and 102 are connected. The drive mechanism 3 includes a drive motor 301 and a drive wheel 302. The drive motor 301 is fixedly installed in the groove 101, and the drive wheel 302 is disposed in the groove 102. The drive wheel 302 is fixedly connected to the output shaft of the drive motor 301 by bolts, and the drive wheel 302 abuts against the lower surface of the fixed disk 201. The outer side of the drive wheel 302 is covered with a rubber sleeve to increase the friction. The drive motor 301 is a stepper motor. Each rotation cycle of the two drive motors 301 will cause the fixed disk 201 to rotate 60°.

[0042] It should be noted that the adsorption mechanism 4 includes an air extraction port 401 extending from the side of the substrate body 1. The upper end of the substrate body 1 has six sets of connection ports 402 extending from the fixed base plate 207 in the six sets of through slots 204. The six sets of connection ports 402 are connected to the air extraction port 401. By connecting a negative pressure device to the outside of the air extraction port 401, the negative pressure device will cause the connection port 402 to draw in air.

[0043] A suction cup 210 is installed on the upper end of the fixed base plate 207, and an adapter 211 is provided on the lower end of the fixed base plate 207. A rubber hose 212 is connected to the lower end of the adapter 211. A bracket 213 is welded and fixed to the outer side of the lower part of the through groove 204. An adapter pipe 214 is integrally formed in the middle of the bracket 213. The upper end of the adapter pipe 214 is connected to the rubber hose 212, and a one-way valve is installed inside the adapter pipe 214. The connection between the connection port 402 and the adapter pipe 214 is... The surface is sealed with a rubber ring. Each rotation of the fixing plate 201 aligns the connection port 402 and the adapter pipe 214. After the glass cover is placed on the fixing base plate 207, the suction cup 210 is fixed to the glass cover by the vacuum pump through the negative pressure device. The adapter pipe 214 has a one-way valve. When the connection port 402 and the adapter pipe 214 are misaligned due to the rotation of the fixing plate 201, the lower end of the suction cup 210 will not leak air and cause the glass cover to fall off.

[0044] It should be noted that the central lighting mechanism 5 includes a central support column 501 welded and fixed to the base plate body 1. The central support column 501 is located inside the central fixing ring 202, and a light strip 502 is bonded and fixed to the outer side of the upper part of the central support column 501. Six sets of light strips 502 are arranged in a circular array, and a light shield 503 is integrally formed at the top of the central support column 501. When the fixed base plate 207 is rotated to a non-horizontal angle, the light strip 502 illuminates the glass cover plate fixed on the fixed base plate 207. The glass cover plate will reflect light to the visual inspection mechanism 8 above. The diffuse reflection area will be very obviously exposed, and the light shield 503 can prevent the light from the light strip 502 from directly shining on the visual inspection mechanism 8.

[0045] In particular, in this invention, two sets of transverse drive mechanisms 6 are symmetrically arranged, and the transverse drive mechanism 6 includes a second drive motor 601 and a side plate 602. The side plate 602 is welded to the upper end of the base plate body 1, and the second drive motor 601 is installed on one side of the side plate 602 by bolts. The side plates 602 are rotatably connected by a lead screw 603 through bearings. The lead screw 603 is connected to the output shaft of the second drive motor 601 through a key. The longitudinal drive mechanism 7 is connected to the upper end of the lead screw 603. The two second drive motors 601 in the transverse drive mechanism 6 rotate synchronously, which can drive the longitudinal drive mechanism 7 to move laterally above the lead screw 603.

[0046] It should be noted that the longitudinal drive mechanism 7 includes a side column 701, the lower end of which is integrally formed with a slide block 702. A slide groove 703 is formed on the lower part of the slide block 702, and a T-shaped slide rail 103 is integrally formed on the upper end of the base plate body 1. The slide block 702 is sleeved onto the T-shaped slide rail 103 through the slide groove 703. Four sets of rollers 704 are rotatably connected to the lower end of the slide groove 703. The rollers 704 abut against the upper surface of the T-shaped slide rail 103. Furthermore, the side of the slide block 702 is integrally formed with… The drive block 705 has a threaded hole 706, which is threaded to the lead screw 603. The drive motor 707 is fixedly installed on the outer side of the top of the side column 701. The output shaft of the drive motor 707 is fixedly connected to the lead screw 708 via a flat key. The vision inspection mechanism 8 is driven by the lead screw 708. The roller 704 can reduce the resistance of the longitudinal drive mechanism 7 and the T-shaped slide rail 103, making the lateral movement of the longitudinal drive mechanism 7 smoother.

[0047] In particular, in this invention, the visual inspection mechanism 8 includes a crossbar 801, with threaded holes 802 at both ends of the crossbar 801, which are threaded to a lead screw 708. A vertical plate 803 is integrally formed at the upper part of the middle section of the crossbar 801, and an industrial camera 804 is fixedly connected to one side of the vertical plate 803. A fixing seat 805 is integrally formed at the middle section of the crossbar 801, with a circular through groove 806 on the fixing seat 805. A ring light 807 is installed at the lower end of the fixing seat 805. 07 is located outside the through slot 806, and the industrial camera 804 is located directly above the through slot 806. Through the synchronous rotation of two sets of drive motors 707, the crossbar 801 can be driven to move up and down. Initially, the industrial camera 804 is located at the top of the travel. The industrial camera 804 can detect all the fixed glass covers. When an abnormality is detected, the industrial camera 804 is driven down by the drive motor 707, and at the same time, the abnormal back panel is re-inspected to improve the accuracy of the detection.

[0048] The present invention is used in the following steps:

[0049] S1: Place the glass cover plate onto the six sets of fixed base plates 207 in the glass cover plate fixing mechanism 2, and start the external negative pressure device to generate negative pressure to fix the upper glass cover plate.

[0050] S2: Inspect the fixed glass cover plate using the industrial camera 804 in the vision inspection mechanism 8;

[0051] S3: When an abnormal glass cover is detected, the upper fixed plate 201 is rotated by the drive motor 301, so that the abnormal glass cover is rotated to below the path of the lateral movement of the vision inspection mechanism 8.

[0052] S4: Drive the vision inspection mechanism 8 downward by the drive motor 3707 to further inspect the abnormal glass cover;

[0053] S5: After the glass cover is inspected in a horizontal state, the glass cover is tilted by rotating the fixed base plate 207. Then the visual inspection mechanism 8 is moved to the top again and the central lighting mechanism 5 is activated to perform the inspection again.

[0054] S6: After detecting an abnormal glass cover in a tilted state, the upper fixed plate 201 is rotated by the drive motor 301, so that the abnormal glass cover is rotated to below the path of the lateral movement of the vision inspection mechanism 8.

[0056] S8: After the test is completed, remove the glass cover plate attached to the upper part of the suction cup 210.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
