Description

Technical Field

[0001] The present invention belongs to the technical field of visual inspection, and particularly relates to a micro-transformer detection production line and a detection method. Background Art

[0002] A micro-transformer is a transformer with a relatively small size, usually used in low-voltage environments. They are widely used in various electronic devices, such as handheld devices, power adapters for laptop computers, and various portable electronic devices, etc. The design goal of micro-transformers is mainly to reduce volume and weight while maintaining high efficiency and reliability. As shown in the attached Figure 11 , the width of a common micro-transformer is between 20 - 96 mm. During the production process of micro-transformers, multiple inspections are required, and appearance inspection is a relatively important item. The following problems exist when performing appearance inspection on micro-transformers: 1. When performing appearance inspection on micro-transformers, industrial vision inspection technology is usually used. The micro-transformer is photographed by a CCD camera, and the photographed photo is compared with the photos of qualified products in the database to detect whether the transformer is qualified. However, the sizes of different models of transformers are different, and during factory production, according to customer requirements, different models of micro-transformers may be produced in the same batch, facing the situation of simultaneously inspecting different models of micro-transformers. However, for existing inspection equipment, the fixtures, the number and positions of CCD cameras, and the corresponding supporting equipment required for inspecting different models of micro-transformers all need to be adjusted accordingly, making it difficult to simultaneously inspect different models of micro-transformers. Even, it may be necessary to replace different inspection equipment for inspection, resulting in high costs and low efficiency.

[0003] 2. Whether the micro-transformer is directly shipped after production or shipped after being stocked, it needs to be inspected before shipment. During production and stocking, debris and impurities will be generated on the micro-transformer, which will affect the inspection results. Therefore, the dust removal step is necessary. Existing inspection equipment generally does not have a dust removal function and all perform inspection after a separate dust removal step, increasing the inspection time consumption and being inefficient. Moreover, the dust removal step requires a separate drive source, increasing the equipment usage cost. During dust removal, the micro-transformer usually remains stationary, and air is directly blown for dust removal. It is difficult for the gas to reach all surfaces of the micro-transformer, resulting in poor dust removal effect.

[0004] When detecting the appearance of a micro-transformer, usually a CCD camera is used to take a single-angle shot of the micro-transformer, which can only detect whether there are defects in the micro-transformer at a single angle. The detection error is relatively large, reducing the accuracy of detection. Since cracks, oil leakage marks or rust on the transformer shell may be distributed on different sides of the transformer, and the obviousness of these defects often varies at different angles and may not even be directly observable at some specific angles, it is necessary to observe the transformer from multiple angles. When detecting the appearance of a micro-transformer, usually a CCD camera is used to take a single-angle shot of the micro-transformer, which can only detect whether there are defects in the micro-transformer at a single angle.

[0015] A method for detecting a micro-transformer, based on the above-mentioned micro-transformer detection production line, the method for detecting the micro-transformer includes the following steps: S1. Feeding and positioning blocking: First, use a conveyor belt to convey micro-transformers of different sizes from right to left, and use a limiting and blocking mechanism to block and position the micro-transformers.

[0016] S2. Adaptive clamping: After positioning and blocking, use a moving mechanism to move the multi-point adaptive clamping mechanism to the top of the micro-transformer. At this time, use the multi-point adaptive clamping mechanism to simultaneously and adaptively clamp and fix a plurality of micro-transformers of different sizes.

[0017] S3. Rotating and photographing: When different models of micro-transformers are synchronously clamped and stable, use the moving mechanism to move the clamped micro-transformer into the base until it descends until the roller is stuck into the limiting sliding rail. As the moving mechanism drives different models of micro-transformers to move from right to left, until the second driving gear on the multi-point adaptive clamping mechanism meshes with the first rack, and as it moves, the micro-transformer is driven to rotate.

[0018] S4. Automatic dust removal: As the moving mechanism drives different models of micro-transformers to move from right to left, the multi-point adaptive clamping mechanism drives the air-blowing dust-removing mechanism to rotate and jet air synchronously, facilitating blowing and cleaning different surfaces of the micro-transformer.

[0019] S5. Visual inspection: As the micro-transformer moves from right to left, the CCD industrial camera takes photos of each surface of the micro-transformer moving from right to left. After the shooting is completed, the photos are transmitted to the background processor, where they are compared with the existing qualified products of the micro-transformer and feature recognition is carried out. If an incorrect feature is recognized, it indicates that there are defects in the appearance of the micro-transformer, and the detection result is directly displayed on the monitor.

[0020] The beneficial effects of the present invention are as follows: 1. The present invention uses a multi-point adaptive clamping mechanism to adaptively clamp multiple micro-transformers of different models at the same time, realizing synchronous detection of multiple micro-transformers of different models in the same batch by a single detection device, expanding the scope of application of the device, improving the detection efficiency, and enabling the one-time clamping and fixation of transformers of different models by a single hydraulic cylinder without replacing the fixture.

[0021] 2. After the present invention stably clamps the micro-transformer using the multi-point adaptive clamping mechanism, during the process of conveying from right to left, through the cooperation of the first rack and the second driving gear, the transformer rotates while being detected. Multiple photos taken by the ccd camera are comprehensively judged to determine whether there is oil leakage, rust or cracks on the outside of the transformer. At the same time, rotating during detection facilitates the leakage of the heat dissipation silicone grease inside the transformer from the gaps through the action of centrifugal force, making it easier to show the obviousness of the cracks. At the same time, rotating during detection can simulate the working state of some special transformers to ensure that there is no scratching or abnormal magnetic circuit in their working state.

[0022] 3. When the micro-transformer rotates and conveys from right to left, the second driving gear drives the air blowing and dust removal mechanism to work synchronously while rotating. The air blowing and dust removal mechanism evenly blows and removes dust from each surface of the micro-transformer, with good dust removal effect. Moreover, the micro-transformer itself rotates, realizing the automatic throwing out of dust and further improving the dust removal effect.

[0023] 4. When the transverse movement mechanism drives the micro-transformer to move horizontally, it synchronously drives the rotation of the clamping component, thereby realizing the rotation of the micro-transformer. At the same time, it drives the rotation of the suction blades in the air blowing and dust removal mechanism, thereby realizing blowing and dust removal while rotating during the horizontal movement. The rotation of the clamping component and the rotation of the suction blades are linked, and no additional driving source is required. Description of the Drawings

[0035] Please refer to Figure 5 , Figure 6 and Figure 7 , the clamping assembly 74 includes a plurality of side plates 740 symmetrically fixedly connected to the bottom of the right side of the back plate 72. The side plates 740 are grouped in pairs. A first fixed rod 744 is fixedly connected between two side plates 740 in the same group. Two connecting plates 743 are slidably connected to the first fixed rod 744 symmetrically in the front and rear.

[0036] During use, when the multi-point adaptive clamping mechanism 7 is located at the top of the micro-transformer to be clamped, the servo motor 62 is started at this time. The output end of the servo motor 62 drives the screw rod 64 to rotate, and at the same time drives the movable block 61 and the second fixing rod 75 thereon to move downward, synchronously driving the back plate 72, the adaptive lifting assembly 73 and the clamping assembly 74 to move downward synchronously until the clamping plate 746 is on both sides of the micro-transformer to be clamped.

At this time, the downward pressing wedge 738 squeezes the pressed wedge 749, synchronously driving the pressed wedges 749 on both sides and the connecting plate 743 thereon to move towards each other, synchronously compressing the spring 745, and at the same time driving the movable plate 747 and the rotating plate 748 thereon to move towards each other, and then synchronously driving the two clamping plates 746 to move towards each other, realizing the clamping and fixing of the micro-transformer. When the micro-transformer under a certain second rack 734 is stably clamped, the second rack 734 is locked at this time. At this time, with the continuous descent of the hydraulic cylinder 711, the first driving gear 716 starts to rotate around the fixed shaft 717, driving the other second rack 734 opposite to the locked second rack 734 to continue to move downward, continuing to drive the corresponding downward pressing wedge 738 to squeeze the corresponding pressed wedge 749, indirectly driving the clamping plate 746 under the second rack 734 to clamp and fix the micro-transformer. And when one side of the connecting rod 715 is locked and fixed, the lifting rod 714 deflects at this time, and the connecting rod 715 on the other side and the structure thereon continue to move downward, thereby realizing the clamping and fixing of the micro-transformer with a smaller size, and realizing the synchronous clamping and fixing of micro-transformers of different models under the drive of a single hydraulic cylinder 711.

The transmission ratio between the second driving gear 741 and the first driven gear 21 is 1:6, and the transmission ratio between the first driven gear 21 and the second driven gear 27 is 1:3. The second connecting shaft 29 rotatably penetrates through the center of the side of the suction box 22 close to the movable plate 747. At the end of the second connecting shaft 29 away from the movable plate 747, a plurality of suction blades 24 are uniformly and fixedly connected to the outside. The suction blades 24 are located inside the suction box 22. At the bottom of the suction box 22, a suction pipe 25 is fixedly connected. At the end of the suction pipe 25 away from the suction box 22, it is fixedly connected to the movable plate 747. On the outside of the end of the suction pipe 25 away from the suction box 22, air jet pipes 26 for cleaning and dust removing the surface of the micro-transformer are uniformly and fixedly connected. On both the front and rear sides of the base 1, limiting slide rails 13 are fixedly installed. At the bottom of both the front and rear sides of the back plate 72, fixed arms 18 are fixedly installed. At the bottom of the fixed arm 18, a first U-shaped frame 17 is fixedly installed. At the bottom of the first U-shaped frame 17, a roller 16 cooperating with the limiting slide rail 13 is rotatably connected.

[0038] During use, after micro-transformers of different models are stably clamped, the moving mechanism 6 drives the micro-transformer to move upward first, cross the baffle 31, and then move from right to left until the micro-transformer moves to the top of the base 1. At this time, the moving mechanism 6 drives the multi-point adaptive clamping mechanism 7 and the clamped micro-transformer thereon to move downward, shortening the distance between the micro-transformer and the CCD industrial camera 15, ensuring the quality of the photo shooting, and at the same time drives the fixed arm 18 and the No. 1 U-shaped frame 17 thereon to move downward, synchronously driving the roller 16 to move downward until the roller 16 moves into the groove at the top of the limit slide 13. At this time, the No. 2 driving gear 741 is not in contact with the No. 1 rack 8. The limiting connection between the roller 16 and the limiting slide rail 13 ensures the accuracy of the micro-transformer's movement from right to left. At this time, as the moving mechanism 6 drives the multi-point adaptive clamping mechanism 7 and the micro-transformer clamped thereon to move from right to left, when the No. 2 driving gear 741 is in contact with the No. 1 rack 8, as it moves from right to left, the No. 2 driving gear 741 and the mounting shaft 742 thereon start to rotate, and at the same time drive the rotating plate 748 and the clamping plate 746 to rotate, and then synchronously drive the rotation of the micro-transformer, realizing the micro-transformer's movement from right to left while rotating. During the rotation process, the CCD industrial camera 15 with a pre-set spacing is used to take pictures of each surface of the micro-transformer. The captured images are sent to the background processor for feature recognition, analysis and comparison, and the analysis results are directly displayed on the display 11, which enables the transformer to rotate while being inspected. The multiple photos taken by the CCD industrial camera 15 are used to comprehensively judge whether there is oil leakage, rust or cracks on the outside of the transformer. At the same time, by rotating during inspection, the heat dissipation silicone grease inside the transformer is easily leaked from the gaps due to the action of centrifugal force, which is more convenient to show the visibility of the cracks. At the same time, by rotating during inspection, the working state of certain special transformers can be simulated to ensure that there is no scratch or magnetic circuit abnormality in its working state. The spacing of the CCD industrial camera 15 can be adjusted according to the actual situation. It is adjusted according to the size of the micro-transformer and the moving speed of the moving mechanism 6. When the No. 2 driving gear 741 rotates, it synchronously drives the No. 1 driven gear 21 to rotate rapidly, and at the same time drives the No. 2 driven gear 27 and the No. 2 connecting shaft 29 thereon to rotate rapidly, and synchronously drives the suction blade 24 to rotate and suck, and the outside air is drawn into the suction box 22, and then transported to the jet pipe 26 through the suction pipe 25 for ejection. The ejected air is used to blow and clean the surface of the micro-transformer, and the micro-transformer itself rotates continuously, thereby realizing the cleaning of different surfaces of the micro-transformer and improving the cleaning effect. In the process of rotation of the micro-transformer itself, dust is thrown off, further improving the cleaning efficiency.

[0039] It should be noted that for the micro-transformer detection production line and detection method, during use, first, different models of micro-transformers to be tested are intermittently conveyed from right to left through the conveyor belt 5. The limit blocking mechanism 3 is used to block and limit the different models of micro-transformers being conveyed. Subsequently, the moving mechanism 6 drives the multi-point adaptive clamping mechanism 7 to move above the micro-transformer. At this time, the multi-point adaptive clamping mechanism 7 integrally clamps and fixes multiple different models of micro-transformers, achieving synchronous clamping and fixing of different models of micro-transformers under the drive of a single hydraulic cylinder 711. After stable clamping, the moving mechanism 6 drives the micro-transformer to move into the base 1. At this time, as the moving mechanism 6 drives the micro-transformer to move from right to left, after the second driving gear 741 contacts and meshes with the first rack 8, as it moves from right to left, it drives the second driving gear 741 and its mounting shaft 742 to start rotating, and at the same time drives the rotating plate 748 and the clamping plate 746 to rotate, thereby synchronously driving the rotation of the micro-transformer, achieving the movement of the micro-transformer from right to left while rotating. During the rotation process, the CCD industrial camera 15 with a preset spacing is used to photograph each surface of the micro-transformer. And while the second driving gear 741 rotates, it synchronously drives the air blowing and dust removal mechanism 2 to work, and the air blowing and dust removal mechanism 2 is used to blow and remove dust from the micro-transformer. The micro-transformer itself rotates continuously, achieving the cleaning of different surfaces of the micro-transformer, improving the cleaning effect. And during the rotation process of the micro-transformer itself, ash is thrown off, further improving the cleaning efficiency. The pictures of each surface of the micro-transformer taken by the CCD industrial camera 15 are transmitted to the background processor for feature recognition and comparative analysis. If an incorrect feature is recognized, it indicates that there are defects in the appearance of the micro-transformer. The defect points include: whether there are cracks or depressions on the surface, whether the labels and markings are missing, whether the pins are bent or lack soldering, whether the accessories are installed in place, and whether the key dimensions are qualified. The detection results are directly displayed on the display 11.

[0040] Please refer to Figure 12 , a micro-transformer detection method, based on the above-mentioned micro-transformer detection production line, the micro-transformer detection method includes the following steps: S1. Feeding and positioning block: First, use the conveyor belt 5 to convey micro-transformers of different sizes from right to left, and use the limit blocking mechanism 3 to block and position the micro-transformers; S2. Adaptive clamping: After positioning and blocking, use the moving mechanism 6 to move the multi-point adaptive clamping mechanism 7 to the top of the micro-transformer. At this time, use the multi-point adaptive clamping mechanism 7 to simultaneously and adaptively clamp and fix multiple micro-transformers of different sizes; S3. Rotational shooting: When the micro-transformers of different models are stably clamped synchronously, the mobile mechanism 6 is used to move the clamped micro-transformer into the base 1 until it descends to the roller 16 is caught in the limit slide rail 13. As the mobile mechanism 6 drives the micro-transformers of different models to move from right to left, until the second driving gear 741 on the multi-point adaptive clamping mechanism 7 meshes with the first rack 8, and as it moves, it drives the micro-transformer to rotate; S4. Automatic dust cleaning: As the mobile mechanism 6 drives the micro-transformers of different models to move from right to left, the multi-point adaptive clamping mechanism 7 drives the air blowing and dust removing mechanism 2 to rotate and jet air synchronously, facilitating air blowing and cleaning of different surfaces of the micro-transformer; S5. Visual inspection: As the micro-transformer moves from right to left, the CCD industrial camera 15 takes photos of each surface of the micro-transformer moving from right to left. After the shooting is completed, it is transmitted to the background processor for comparison and feature recognition with the existing qualified products of the micro-transformer. If an incorrect feature is recognized, it indicates that there are defects in the appearance of the micro-transformer. The defect points include: whether there are cracks or depressions on the surface, whether the labels and markings are missing, whether the pins are bent or lack welding, whether the accessories are installed in place, and whether the key dimensions are qualified. The test results are directly displayed on the display 11.
