Description

Technical Field

[0001] The invention relates to the technical field of visual inspection, and in particular to an automatic visual inspection device for materials. Background Art

[0002] Visual inspection technology is a detection method based on machine vision. It uses optical imaging equipment to obtain images of objects, and then uses image processing and analysis algorithms to process and interpret the images to detect and identify the size, shape, color, defects and other features of the object. This technology has the advantages of high precision, high speed, non-contact measurement, and good repeatability.

[0003] In the prior art, after the material products are produced, they need to be inspected. In the prior art, manual visual inspection of the appearance and size of the material products is often used, resulting in poor ability to identify product quality and high labor costs, which reduces the overall inspection efficiency. Summary of the invention

[0004] Based on this, the purpose of the present invention is to provide an automatic visual inspection device for materials to solve the technical problem that the prior art often uses manual visual inspection to inspect the appearance dimensions of material products, resulting in poor ability to identify product quality and high labor costs, thereby reducing the overall inspection efficiency.

[0005] To achieve the above object, the present invention provides the following technical solution: an automatic visual inspection device for materials, comprising a main body, a rotating disk is rotatably connected to the top of the main body, and a fixing frame is fixed inside the main body;

[0006] A first support plate and a second support plate are fixed to one end of the fixing frame, a swing arm is rotatably connected inside the first support plate, and the swing arm and the first support plate are rotatably connected via a movable shaft, a through hole is provided inside the swing arm, a driving shaft is movably connected to the end of the second support plate, a driving arm is fixed to the top of the driving shaft, a driving rod extending into the through hole is fixed to the top end of the driving arm, and the driving rod and the swing arm are movably connected via the through hole;

[0007] A matching plate is fixed to the top end of the swing arm, a swing column extending to the top of the rotating disk is fixed to one end of the top of the matching plate, and a visual detection module is fixed to the top of the swing column;

[0008] A dual-axis motor is fixed inside the main body, a mounting cylinder matched with the dual-axis motor is fixed at one end of the fixing frame, and a mounting cavity matched with the dual-axis motor is opened inside the mounting cylinder, a gear is fixed on the top output shaft of the dual-axis motor, a gear ring meshing with the gear is fixed inside the rotating disk, a driving wheel located below the second supporting plate is fixed on the outside of the driving shaft, and the bottom output shaft of the dual-axis motor and the driving wheel are connected through a transmission belt;

[0009] A wiring hole is provided at one end of the swing column, and the wiring hole and the internal cavity of the swing column are interconnected, and the external power supply wire passes through the wiring hole and the internal cavity of the swing column in turn to be electrically connected to the visual detection module.

[0010] By adopting the above technical solution, the rotating disk is driven to rotate slowly by the dual-axis motor, gears and ring gear. When the material product moves from the loading plate to the top of the rotating disk, the dual-axis motor is started, and the rotating disk drives the material product to rotate slowly in a circle. At the same time, the dual-axis motor drives the drive shaft to rotate through the transmission belt and the driving wheel, and then the rotation of the drive shaft drives the drive arm to rotate. Since the driving rod at the end of the driving arm extends into the through hole inside the swing arm, the rotating driving rod drives the swing arm to swing back and forth in a circle along the movable axis. When the material product moves to one side of the inside of the protective cover, the swing arm just swings above the material product, and the visual inspection module starts to inspect the material product. During the inspection process, as the dual-axis motor continues to rotate, the swing arm drives the visual inspection module to move synchronously with the material product. That is to say, the visual inspection module performs visual inspection on the material product synchronously during its movement, thereby improving the inspection quality and efficiency of the material product.

[0011] Furthermore, a guide groove is provided at one end of the bottom of the rotating disk, a guide column extending into the guide groove is fixed at the top of the matching plate, and the guide column and the guide groove are slidably connected.

[0012] By adopting the above technical solution, the cooperation of the guide column and the guide groove makes the swing arm more stable during the swinging process, thereby improving the stability of the visual inspection module during the visual inspection process.

[0013] Furthermore, a protective cover located on the top of the rotating disk is fixed to one end of the main body, and a matching groove matching with the visual detection module is opened on the inner wall of the protective cover.

[0014] By adopting the above technical solution, the protective cover plays a role in preventing external impurities from affecting the visual inspection process when the visual inspection module inspects material products.

[0015] Furthermore, a loading plate, a good product unloading plate and a low-quality product unloading plate are respectively fixed to the outside of the main body, and the top surfaces of the loading plate, the good product unloading plate and the low-quality product unloading plate are flush with the surface of the rotating disk.

[0016] By adopting the above technical solution, when the visual inspection module detects that the material product is a good product, the good material is pushed out of the rotating disk through the good product discharge plate by the external pushing mechanism; when the visual inspection module detects that the material product is a poor quality product, the poor quality material is pushed out of the rotating disk through the poor quality discharge plate by the external pushing mechanism, thereby completing the sorting operation.

[0017] Furthermore, the two sides of the fixing frame are fixedly connected to the inner wall of the main body through two groups of connecting plates, and the connecting plates, the fixing frame and the main body are all fixedly connected through multiple groups of bolts.

[0018] By adopting the above technical solution, the connecting plate plays a role of fixing and supporting the fixing frame.

[0019] To sum up, the present invention mainly has the following beneficial effects: the present invention drives the rotating disk to rotate slowly through a dual-axis motor, gears and a gear ring. When the material product moves from the loading plate to the top of the rotating disk, the dual-axis motor is started, and the rotating disk drives the material product to rotate slowly in a circular manner. At the same time, the dual-axis motor drives the driving shaft to rotate through the transmission belt and the driving wheel, and then the driving shaft rotation drives the driving arm to rotate. Since the driving rod at the end of the driving arm extends into the through hole inside the swing arm, the rotating driving rod drives the swing arm to swing back and forth in a circular manner along the movable axis. When the material product moves to one side of the inside of the protective cover, the swing arm just swings above the material product, and the visual inspection module starts to inspect the material product. During the inspection process, as the dual-axis motor continues to rotate, the swing arm drives the visual inspection module to move synchronously with the material product. That is to say, the visual inspection module performs visual inspection on the material product synchronously during its movement, thereby improving the inspection quality and efficiency of the material product.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] The following describes an embodiment of the present invention based on its overall structure.

[0030] An automatic visual inspection device for materials, such as Figure 1-7 As shown, it comprises a main body 1, a rotating disk 2 is rotatably connected to the top of the main body 1, and a fixing frame 3 is fixed inside the main body 1;

[0031] A first support plate 7 and a second support plate 11 are fixed at one end of the fixing frame 3, a swing arm 8 is rotatably connected inside the first support plate 7, and the swing arm 8 and the first support plate 7 are rotatably connected via a movable shaft 9, a through hole 10 is provided inside the swing arm 8, a driving shaft 12 is movably connected to the end of the second support plate 11, a driving arm 15 is fixed to the top of the driving shaft 12, a driving rod 16 extending to the inside of the through hole 10 is fixed to the top end of the driving arm 15, and the driving rod 16 and the swing arm 8 are movably connected via the through hole 10;

[0032] A matching plate 19 is fixed to the top end of the swing arm 8, a swing column 17 extending to the top of the rotating disk 2 is fixed to one end of the top of the matching plate 19, and a visual inspection module 18 is fixed to the top of the swing column 17. The rotating disk 2 is driven to rotate slowly through the dual-axis motor 4, the gear 5 and the ring gear 6. When the material product moves from the loading plate 23 to the top of the rotating disk 2, the dual-axis motor 4 is started, and the rotating disk 2 drives the material product to rotate slowly in a circular manner;

[0033] At the same time, the dual-axis motor 4 drives the driving shaft 12 to rotate through the transmission belt 14 and the driving wheel 13, and then the driving shaft 12 rotates to drive the driving arm 15 to rotate. Since the driving rod 16 at the end of the driving arm 15 extends into the through hole 10 inside the swing arm 8, the rotating driving rod 16 drives the swing arm 8 to make it reciprocating and circularly swing along the movable shaft 9;

[0034] When the product material moves to one side of the protective cover 22, the swing arm 8 swings just above the product material, and the visual inspection module 18 starts to inspect the product material. During the inspection, as the dual-axis motor 4 continues to rotate, the swing arm 8 drives the visual inspection module 18 to move synchronously with the product material.

[0035] A dual-axis motor 4 is fixed inside the main body 1, a mounting cylinder 26 matched with the dual-axis motor 4 is fixed at one end of the fixing frame 3, and a mounting cavity matched with the dual-axis motor 4 is opened inside the mounting cylinder 26, a gear 5 is fixed to the top output shaft of the dual-axis motor 4, a gear ring 6 meshing with the gear 5 is fixed inside the rotating disk 2, a driving wheel 13 located below the second support plate 11 is fixed to the outside of the driving shaft 12, and the bottom output shaft of the dual-axis motor 4 and the driving wheel 13 are connected through a transmission belt 14;

[0036] A wiring hole 28 is provided at one end of the swing column 17 , and the wiring hole 28 and the internal cavity of the swing column 17 are interconnected, and an external power supply wire passes through the wiring hole 28 and the internal cavity of the swing column 17 in turn to be electrically connected to the visual detection module 18 .

[0037] See also Figure 2 and Figure 4 A guide groove 21 is provided at one end of the bottom of the rotating disk 2, and a guide column 20 extending into the guide groove 21 is fixed to the top of the matching plate 19, and the guide column 20 and the guide groove 21 are slidably connected. The present invention sets the above structure, wherein the cooperation between the guide column 20 and the guide groove 21 makes the swing arm 8 more stable during the swinging process, thereby improving the stability of the visual inspection module 18 during the visual inspection process.

[0038] See also Figure 1 and Figure 7 A protective cover 22 located on the top of the rotating disk 2 is fixed at one end of the main body 1, and a matching groove matching with the visual inspection module 18 is opened on the inner wall of the protective cover 22. By setting the above structure, the protective cover 22 plays a role in preventing external impurities from affecting the visual inspection process when the visual inspection module 18 inspects material products.

[0039] See also Figure 1 and Figure 7A loading plate 23, a good product unloading plate 24 and a low-quality product unloading plate 25 are respectively fixed to the outside of the main body 1, and the top surfaces of the loading plate 23, the good product unloading plate 24 and the low-quality product unloading plate 25 are flush with the surface of the rotating disk 2. The present invention sets the above structure, wherein when the visual inspection module 18 detects that the material product is a good product, the good product material is pushed out of the rotating disk 2 through the good product unloading plate 24 through an external pushing mechanism; when the visual inspection module 18 detects that the material product is a low-quality product, the low-quality product material is pushed out of the rotating disk 2 through the low-quality product unloading plate 25 through an external pushing mechanism, thereby completing the sorting operation.

[0040] See also Figure 4 and Figure 6 The two sides of the fixing frame 3 are fixedly connected to the inner wall of the main body 1 through two groups of connecting plates 27, and the connecting plates 27 and the fixing frame 3 and the main body 1 are fixedly connected through multiple groups of bolts. By setting the above structure, the connecting plates 27 play a role of fixing and supporting the fixing frame 3.

[0041] The working principle of the present invention is: when in use, the power is turned on, wherein the external automatic feeding mechanism is connected to the feeding plate 23, and then the material product can be transported to the top of the rotating disk under the action of the external feeding mechanism;

[0042] The rotating disk 2 is driven to rotate slowly by the dual-axis motor 4, the gear 5 and the ring gear 6. When the material product moves from the loading plate 23 to the top of the rotating disk 2, the dual-axis motor 4 is started, and the rotating disk 2 drives the material product to rotate slowly in a circular manner.

[0043] At the same time, the dual-axis motor 4 drives the driving shaft 12 to rotate through the transmission belt 14 and the driving wheel 13, and then the driving shaft 12 rotates to drive the driving arm 15 to rotate. Since the driving rod 16 at the end of the driving arm 15 extends into the through hole 10 inside the swing arm 8, the rotating driving rod 16 drives the swing arm 8 to make it reciprocating and circularly swing along the movable shaft 9;

[0044] When the product material moves to one side of the protective cover 22, the swing arm 8 swings just above the product material, and the visual inspection module 18 starts to inspect the product material. During the inspection, as the dual-axis motor 4 continues to rotate, the swing arm 8 drives the visual inspection module 18 to move synchronously with the product material.

[0045] That is to say, at this time, the visual inspection module 18 performs visual inspection on the material product synchronously as it moves, thereby improving the inspection quality and inspection efficiency of the material product;

[0046] After a group of material products are tested, the material products are discharged through the other side of the protective cover 22. At this time, as the rotating disk 2 continues to rotate, the tested material products are driven to continue to rotate in a circular manner.

[0047] When the visual inspection module 18 detects that the material product is good, the good material is pushed out of the rotating disk 2 through the good material discharge plate 24 by the external pushing mechanism. When the visual inspection module 18 detects that the material product is bad, the bad material is pushed out of the rotating disk 2 through the bad material discharge plate 25 by the external pushing mechanism, thereby completing the sorting operation.

[0048] In the above sorting process, under the action of the driving arm 15, the swing arm 8 and the visual inspection module 18 are driven to move in a circle from one side of the protective cover 22 to the other side. At this time, the next group of material products to be inspected moves to the bottom of the visual inspection module 18, and then the above steps are repeated to perform visual inspection operations on multiple groups of material products in turn. The visual inspection module 18 can effectively perform visual inspection on the length, width and height of the product, and the overall inspection effect is good, while the inspection efficiency is greatly improved.
