[0029] like Figures 1-6 As shown, a general-purpose device based on high-speed automated visual inspection includes an auxiliary line 2, an infeed line 3, an inspection line 4, an outfeed line 5, and an inspection unit 6 mounted on a frame 1. The auxiliary line 2, infeed line 3, inspection line 4, and outfeed line 5 are all stepper conveyor lines. The two ends of the inspection line 4 are respectively equipped with the infeed line 3 and the outfeed line 5, forming a U-shaped conveyor line. The U-shaped conveyor line is located on one side of the auxiliary line 2. The auxiliary line 2 is used to receive the material to be inspected on the production line, and the infeed line 3 is used to transfer the material to be inspected. The material is fed to the testing line 4. The discharge line 5 is used to convey the material from the testing line 4 to the auxiliary line 2. The testing unit 6 is used to test the material on the testing line 4. This universal device sorts and conveys the material through the auxiliary line 2. With the help of the push block 1202 of the feeding line 3, the material can be stably, quickly and orderly conveyed to the testing position. Then, the tested material is sent out through the discharge line 5. It has a high degree of automation and high testing efficiency. Moreover, this cooperative structure can meet the online high-speed testing needs of materials of various specifications, shapes and materials.

[0030] Auxiliary line 2 uses existing belt conveyor technology. The feeding line 3, discharging line 5 and detection line 4 have the same structure, but different conveying directions. The feeding line 3 includes a driving wheel, a driven wheel and a synchronous belt. The driving wheel, driven wheel and synchronous belt can be a combination of synchronous pulley and belt, or a combination of sprocket and chain, as long as synchronous transmission can be met. It will not be elaborated here. The outer ends of the driving wheel and the outer ends of the driven wheel are respectively rotated and sleeved on the frame 1. The inner ring of the middle of the driving wheel is fixedly sleeved on the drive of the first motor, and the outer ring of the first motor is fixedly connected to the frame 1.

[0031] Meanwhile, during implementation, the scraper 12 can be selected from various structures. In this embodiment, both the scraper 12 of the feed line 3 and the scraper 12 of the discharge line 5 are selected from the first embodiment, such as... Figure 4As shown, the scraper 12 comprises a support rod 1201 and a pushing block 1202 arranged at one end of the support rod 1201, and the other end of the support rod 1201 is fixedly connected to the synchronous belt.

[0032] In order to avoid the scraper 12 of the detection line body 4 from interfering with the feeding line body 3, the discharge line body 5 and other functional components, the scraper 12 is selected as Figure 5 As shown in the second embodiment, the scraper 12 comprises a pushing block 1202 and a support rod 1201 arranged at both ends of the pushing block 1202, and one end of each support rod 1201 is fixedly connected to the synchronous belt.

[0033] The pushing block 1202 of the above two embodiments has the same structure, and in order to realize the self-adaptive positioning of the material during the movement, a positioning structure for self-adaptive positioning of the material is arranged at one end of the pushing block 1202, and the positioning structure is any one of a positioning groove 1203 or a positioning boss, as Figure 4 and 5 As shown, the arc-shaped positioning groove 1203 is selected in the embodiment, and the periphery of the material can be gradually self-adaptively positioned along the arc-shaped positioning groove 1203 during the movement of the material through the pushing block 1202.

[0034] The first slot plate 9, the second slot plate and the third slot plate 11 are fixedly installed on the frame 1, the first slot plate 9 and the third slot plate 11 are respectively located at both ends of the second slot plate, the detection line body 4 and the auxiliary line body 2 are arranged in parallel with each other, the first slot plate 9 and the third slot plate 11 are located between the detection line body 4 and the auxiliary line body 2, the second slot plate is arranged in parallel with the auxiliary line body 2, the first slot plate 9 is located below the feeding line body 3, the second slot plate is located below the detection line body 4, and the third slot plate 11 is located below the discharge line body 5.

[0035] The upper ends of the first slot plate 9, the second slot plate and the third slot plate 11 are respectively provided with U-shaped grooves, the material can slide in the U-shaped grooves through the scraper 12, and the side walls of the U-shaped grooves are used for limiting the material to prevent the material from falling during the conveying process.

[0036] In order to realize the detection of multiple angles of multiple materials, as shown, one detection unit 6 is arranged above and below the second slot plate, and the CCD camera is selected as the detection unit 6 in the embodiment, the second slot plate is provided with a through hole 101 at the bottom of the U-shaped groove, and the position of the through hole 101 corresponds to the detection unit 6, as Figure 3 As shown, two detection units 6 are arranged above and below in the embodiment, that is, two through holes 101 are arranged, and a detection plate is installed in each through hole 101, and the existing transparent material is selected as the detection plate to realize the purpose of multi-directional shooting detection.

[0037] The frame 1 is provided with a deceleration positioning device, which comprises two opposite clamping plates, each of which comprises a first telescopic rod 8 selected from a push rod air cylinder in the prior art. The outer periphery of the first telescopic rod 8 is fixedly installed on the frame 1, and the movable rod of the first telescopic rod 8 is provided with a deceleration plate 13. One end of the deceleration plate 13 is provided with a felt, which is in contact with the periphery of the material. The felt in contact with the periphery of the material has the advantage of preventing the conveyed material from being hard and scratched. At the same time, the felt of the two opposite clamping plates can also increase the friction force, so as to ensure the buffering and stopping effect.

[0038] At the same time, the felt of the two opposite clamping plates cooperates with the arc-shaped positioning groove 1203, which can also play a role in repositioning the material, thereby improving the accuracy of photographing.

[0039] The auxiliary line body 2 is provided with a pusher assembly 7 for removing defective materials. The pusher assembly 7 is located on one side of the discharge line body 5. The pusher assembly 7 comprises a second telescopic rod, one end of which is used to push the defective materials away from the auxiliary line body 2. The second telescopic rod is selected from a push rod air cylinder in the prior art. By automatically controlling the pushing of the second telescopic rod, the labor is reduced and the work efficiency is improved.

[0040] In the implementation, the first telescopic rod 8 and the second telescopic rod are both connected to the air pump through pipelines. The transmission motor of the auxiliary line body 2, the air pump, the first motor and the detection unit 6 are all signal-connected to the controller. The control mode in the present application is controlled by the controller. The control circuit of the controller can be realized by simple programming by those skilled in the art. The power supply also belongs to the common knowledge in the art. The present application mainly protects the mechanical device, and the control mode and circuit connection will not be explained in detail.

[0041] Working process of the general device based on high-speed automatic visual detection:

[0042] The controller controls the stepwise conveying of the auxiliary line body 2, the feeding line body 3, the detection line body 4 and the discharging line body 5. After the material is conveyed from the assembly line body to the auxiliary line body 2, the material is pushed into the first slot-shaped plate 9 by the pushing block 1202 of the feeding line body 3, and the material is pushed to one end of the second slot-shaped plate along the first slot-shaped plate 9 in a stepwise manner. The arc-shaped positioning groove 1203 can realize the alignment of the material in the pushing process. The pushing block 1202 of the detection line body 4 pushes the material to the detection plate in a stepwise manner. When the material reaches the detection plate, the positions of the materials on the detection plate are not the same due to factors such as inertia without limitation. At this time, the oppositely arranged felt clamp and the periphery of the material realize the stop of the material on the detection plate. At the same time, the arc-shaped positioning groove 1203 of the pushing block 1202 realizes the fine positioning of the material again when the felt applies force to the periphery of the material. Then, the felt resets and falls off and contacts the material, and at the same time, the pushing block 1202 retreats by a preset distance to ensure that there is no interference during shooting and improve the accuracy of shooting and imaging. After shooting is completed, the pushing block 1202 of the detection line body 4 carries the material to the third slot-shaped plate 11, and then the pushing block 1202 of the discharging line body 5 guides the material into the auxiliary line body 2, that is, the online detection is completed. If the defective product is detected online, the controller records the data, and pushes the material by automatically controlling the second telescopic rod, reduces the manual work and improves the work efficiency.

[0043] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
