Description

Technical Field

[0001] This utility model relates to the field of visual inspection technology, specifically a feeding mechanism for visual inspection equipment. Background Technology

[0002] When inspecting items, visual inspection equipment is often used. The inspection head on the visual inspection equipment is set to inspect the items. When inspecting items, a feeding structure is needed to continuously transport the items and achieve continuous inspection. When transporting items, they are usually placed directly on the conveyor belt.

[0003] Most current feeding mechanisms transport products directly via conveyor belts, making it difficult to control the spacing between different types of products. This affects the accuracy of the camera's comparison when taking overhead shots of the products. Existing equipment may use ordinary motors to drive belts or chains, which cannot adjust the speed in real time to match the triggering frequency of the vision inspection camera, resulting in unstable product conveying speed and causing blurry or missed detections in the inspection images. Utility Model Content

[0004] The purpose of this invention is to provide a feeding mechanism for a visual inspection device to solve the problems raised in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a feeding mechanism for a visual inspection device, comprising a base, partitions, a servo motor, and a drive gear. A detection box is positioned directly above the base, and a toothed conveyor belt is positioned on the outer side of the base. A driven roller is positioned on one side of the inner end of the toothed conveyor belt, and a marking mechanism is positioned directly above the toothed conveyor belt. The marking mechanism separates and marks the inspected products using partitions arranged at equal intervals, thereby ensuring efficient product rejection after visual inspection. A conveying mechanism is positioned at the inner end of the toothed conveyor belt, and the conveying mechanism controls the conveying speed of the toothed conveyor belt according to the product specifications, thereby cooperating with a visual inspection camera for image capture.

[0006] As a preferred technical solution, the marking mechanism includes a partition, a strong magnetic strip, a slot, a magnetic groove, a cast iron strip, and a white board. The partition is located above the toothed conveyor belt with equal spacing. The slot is opened at the bottom end of the partition. The white board is bonded to the top of the partition. The magnetic groove is located on the outside of the toothed conveyor belt with equal spacing. The bottom end of the cast iron strip is bonded to the outside of the toothed conveyor belt. The strong magnetic strip is connected to the outside of the slot.

[0007] As a preferred technical solution, the partition is connected to the top of the strong magnet strip through a slot at the bottom, and the strong magnet strip has an inverted "T" shaped structure.

[0008] As a preferred technical solution, the strong magnet strip and the cast iron strip are arranged parallel to each other, and the magnetic groove contacts the outer side of the strong magnet strip through the cast iron strip bonded inside.

[0009] As a preferred technical solution, the conveying mechanism includes a toothed conveyor belt, a servo motor, a toothed rubber sleeve, a conveying roller, a driven gear, and a driving gear. The toothed conveyor belt has a conveying roller inside, and a toothed rubber sleeve is connected to the outside of the conveying roller. A driven gear is provided on one side of the conveying roller, and a driving gear is meshed with one side of the driven gear. The servo motor is mounted on one side of the base, and the output end of the servo motor is connected to the driving gear through a coupling. The outer side of the toothed rubber sleeve meshes with the inner end of the toothed conveyor belt.

[0010] As a preferred technical solution, the output end of the servo motor is connected to the driven gear on the other side via a coupling.

[0011] As a preferred technical solution, the conveyor roller meshes with the driving gear via a driven gear connected by a side key.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a marking mechanism to separate inspected products through equally spaced partitions. When the conveyor belt transports products, the partitions are arranged at equal intervals to ensure that the products are separated and to avoid mutual interference or collision. The bottom end of the partition is connected to a strong magnetic strip through a slot, allowing the partition to be flexibly adjusted in position. The partitions can prevent products from colliding and squeezing each other during transportation, ensuring the stability of the products during transportation. At the same time, the marking mechanism will mark the products according to the detection results of the visual inspection camera. If the product passes the inspection, it may not be specially marked or may be marked with a specific mark.

[0013] 2. This utility model uses the rotation speed of a servo motor to adjust the conveying speed of the toothed conveyor belt, which can meet the conveying speed requirements of different products. Different specifications of products may require different conveying speeds to ensure that the vision inspection camera can clearly and accurately capture the product. For smaller and simpler products, the conveying speed can be appropriately increased to improve inspection efficiency; while for larger and more complex products, the conveying speed needs to be reduced to ensure the accuracy of inspection.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Figures 1 to 5 As shown, this utility model provides the following technical solution: a feeding mechanism for a visual inspection device, including a base 1, a partition 6, a servo motor 7, and a drive gear 16. A detection box 3 is arranged directly above the base 1. A toothed conveyor belt 4 is arranged on the outer side of the base 1. A driven roller 2 is arranged on one side of the inner end of the toothed conveyor belt 4. A marking mechanism 5 is arranged directly above the toothed conveyor belt 4. The marking mechanism 5 separates and marks the inspection products through the partitions 6 arranged at equal intervals, thereby ensuring the efficiency of product rejection after visual inspection. A conveying mechanism 11 is arranged at the inner end of the toothed conveyor belt 4. The conveying mechanism 11 controls the conveying speed of the toothed conveyor belt 4 according to the specifications of the product, thereby cooperating with the visual inspection camera for shooting.

[0019] In this process, the product to be inspected is placed on the toothed conveyor belt 4. The toothed conveyor belt 4 starts to run under the drive of the driven roller 2 and the drive gear 16 (usually the drive gear 16 is driven by the servo motor 7, and the drive gear 16 will drive its operation by meshing with the toothed conveyor belt 4), and transports the product towards the inspection box 3.

[0020] like Figure 1 , Figure 2 and Figure 3As shown, the marking mechanism 5 includes a partition 6, a strong magnetic strip 8, a slot 9, a magnetic groove 10, a cast iron strip 12, and a white board 17. The partition 6 is located above the toothed conveyor belt 4, with the slot 9 at the bottom of the partition 6. The white board 17 is bonded to the top of the partition 6. The magnetic groove 10 is located on the outside of the toothed conveyor belt 4, with the slot 9 at the bottom of the cast iron strip 12. The strong magnetic strip 8 is connected to the outside of the slot 9. The partition 6 is connected to the top of the strong magnetic strip 8 through the slot 9 at the bottom. The strong magnetic strip 8 has an inverted "T" shape structure and is arranged parallel to the cast iron strip 12. The magnetic groove 10 contacts the outside of the strong magnetic strip 8 through the cast iron strip 12 bonded inside.

[0021] The main function of the marking mechanism 5 is to separate the products being transported by the partition 6, and to ensure that the products are separated by the magnetic attraction between the strong magnet strip 8 and the cast iron strip 12. When the toothed conveyor belt 4 transports the products, the partition 6 is arranged at equal intervals to prevent mutual interference or collision. The partition 6 and the white board 17 can be flexibly fixed or adjusted in position. The cast iron strip 12 is fixed in the magnetic groove 10. The magnetic attraction of the strong magnet strip 8 ensures that the white board 17 is stable and will not shift due to the vibration of the conveyor, thereby achieving the marking of the products.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the conveying mechanism 11 includes a toothed conveyor belt 4, a servo motor 7, a toothed rubber sleeve 13, a conveying roller 14, a driven gear 15, and a driving gear 16. The conveying roller 14 is arranged inside the toothed conveyor belt 4, and the toothed rubber sleeve 13 is connected to the outside of the conveying roller 14. The driven gear 15 is arranged on one side of the conveying roller 14, and the driving gear 16 is meshed with one side of the driven gear 15. The servo motor 7 is mounted on one side of the base 1, and the output end of the servo motor 7 is connected to the driving gear 16 through a coupling. The outer side of the toothed rubber sleeve 13 meshes with the inner end of the toothed conveyor belt 4. The output end of the servo motor 7 is connected to the driving gear 16 on the other side through a coupling and meshes with the driven gear 15 on the other side. The conveying roller 14 meshes with the driving gear 16 through a driven gear 15 connected by a key on one side.

[0023] The conveying mechanism 11 controls the conveying speed of the toothed conveyor belt 4 according to the product specifications. Different product specifications may require different conveying speeds to ensure that the visual inspection camera can clearly and accurately capture the product. The speed of the conveyor belt 4 is controlled by adjusting the ratio of the number of teeth between the drive gear 16 and the driven gear 15. At the same time, the captured data is compared with the corresponding machine to remove defective products.

[0024] The working principle of this utility model is as follows: When the toothed conveyor belt 4 conveys products, the partitions 6 are arranged at equal intervals to ensure that the products are separated and to avoid mutual interference or collision. The bottom end of the partition 6 is connected to the strong magnet strip 8 through the slot 9. The operator places the product on the surface of the conveyor belt 4, and then sets the strong magnet strip 8 at the bottom end of the partition 6 parallel to the magnetic groove 10, so that the strong magnet strip 8 at the bottom end of the partition 6 is attracted to the cast iron strip 12, so that the partition 6 and the conveyor belt 4 are magnetically positioned. The output shaft of the servo motor 7 transmits power to the drive gear 16 through a high-precision coupling to ensure no torque loss. The drive gear 16 meshes precisely with the driven gear 15, which drives the conveyor roller 14 to rotate. At the same time, the driven roller 2 with the through groove positions the other side of the conveyor belt 4. The operator nests the toothed rubber sleeve 13 with the outer side of the conveyor roller 14. The two ends of the conveyor roller 14 are fixed by bearings. The toothed rubber sleeve 13 meshes with the tooth groove at the inner end of the toothed conveyor belt 4 to form a bidirectional constraint to prevent the conveyor belt 4 from running off-center or slipping. Whiteboard 17 is attached directly above partition 6 and moves with partition 6 to mark products during transport. Cast iron strip 12 is fixed in magnetic groove 10. The magnetic attraction of strong magnet strip 8 ensures the stability of partition 6 and whiteboard 17 and prevents them from shifting due to transport vibration. Operators can mark the product model on whiteboard 17 first. When the camera takes a picture of the product, it can also take a picture of the product model on whiteboard 17. The product and the corresponding partition 6 are transported into the inspection box 3. The camera is used to take pictures of the product and compare the defects. By marking on whiteboard 17, operators can facilitate the removal of defective products by workers in the next process.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
