Description

Technical Field

[0001] The utility model belongs to the technical field of detection equipment, and in particular relates to a double-turntable automatic visual detection equipment. Background Art

[0002] After metal parts (such as metal parts on mobile phones or computers, but not limited to these) are processed, they generally need to be inspected for appearance, size, etc. to ensure the quality of metal parts and avoid defective parts in good products. There are two main inspection methods. One is manual inspection, or combined with simple measuring fixtures, such as plug gauges, magnifying glasses, etc. This is completely dependent on manual inspection and experience, and has high requirements for operators, low efficiency, and low inspection accuracy. The second is to use inspection equipment to collect data with visual inspection cameras for automatic inspection. However, some parts require multiple faces, multiple sizes, and multiple appearance defects to be inspected. The existing single turntable or conveyor belt loading, and the number of cameras set up nearby for inspection is limited, and cannot meet the above inspection requirements.

[0003] The purpose of the utility model is to provide a double-turntable automatic visual inspection device to overcome the above problems. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a dual-turntable automatic visual inspection equipment. Through the structural design of the two turntables, visual inspection of the product on multiple surfaces and multiple angles such as the bottom, side and top can be carried out. The inspection is more comprehensive, the equipment structure is more compact, and the degree of automation is high.

[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a double-turntable automatic visual inspection device, comprising a machine platform and a first turntable and a second turntable in a rotatable annular shape arranged on the machine platform, wherein a vibrating feeding mechanism is arranged upstream of the first turntable, and a feeding end of the vibrating feeding mechanism is connected to a disk surface of the first turntable;

[0006] The first turntable is a transparent glass turntable, and a first visual inspection device for inspecting the product from below is provided on the first turntable. The first visual inspection device is provided on the machine platform and is located directly below the first turntable;

[0007] The second turntable is a metal turntable, and a plurality of second visual inspection devices for inspecting the product from above and a plurality of third visual inspection devices for inspecting the product from the side are arranged on the second turntable, and the second visual inspection devices and the third visual inspection devices are arranged on the machine platform;

[0008] The first turntable and the second turntable are butt-jointed, and a material guiding structure is provided at the joint between the two, through which the product is guided from the first turntable to the second turntable.

[0009] Furthermore, the vibration feeding mechanism is a vibration disc type feeding mechanism.

[0010] Furthermore, a first lower material bin is provided around the first turntable, and a first blowing nozzle is provided at the center of the first turntable. The first blowing nozzle is aimed at the first material bin, and defective products are blown into the first material bin through the first blowing nozzle.

[0011] Further, the material guide structure includes a first material guide component and a second material guide component, the first material guide component includes a first material guide frame and an arc-shaped first material guide piece installed on the first material guide frame, the height of the first material guide frame and the position of the first material guide piece from the center of the first turntable can be adjusted; the first material guide piece is bent toward the direction of the first turntable;

[0012] The second material guide assembly includes a second material guide rack and a second material guide sheet and a third material guide sheet installed on the second material guide rack, wherein the height of the second material guide rack and the position of the second material guide sheet and the third material guide sheet from the center of the second turntable can be adjusted; the second material guide sheet and the third material guide sheet are both bent toward the direction of the second turntable, and the second guide sheet is located on the inner side of the third guide sheet.

[0013] Furthermore, the material guide structure also includes a third material guide component, the third material guide component includes a third material guide frame and a fourth material guide sheet, the fourth material guide sheet can be adjusted in height of the third material guide frame and in position from the center of the second turntable, and the fourth material guide sheet is in the shape of a flat plate.

[0014] Furthermore, there are multiple second lower material bins arranged at intervals along the circumference of the edge of the second turntable and multiple second blowing nozzles located at the center of the second turntable. The blowing nozzles correspond one-to-one to the second lower material bins, and the products are blown into the corresponding second lower material bins through the second blowing nozzles.

[0015] Furthermore, the first visual inspection device, the second visual inspection device and the third visual inspection device are industrial cameras.

[0016] Furthermore, two vibration feeding mechanisms are provided.

[0017] The beneficial effects of the utility model are:

[0018] The utility model adopts a vibration feeding mechanism to automatically feed the material. When the product is on the first turntable, the first visual inspection device detects the bottom surface of the product from below. Then the product moves to the second turntable through the material guide mechanism. The second visual inspection device and the third visual inspection device can perform visual inspections on multiple surfaces and multiple angles such as the side and top of the product, so the inspection is more comprehensive and the degree of automation is high.

[0019] Furthermore, the visual inspection equipment uses two turntables combined with multiple visual inspection devices to achieve multi-directional inspection of products, and the equipment structure is more compact and occupies less space;

[0020] Furthermore, since it is necessary to inspect the bottom surface of the product (for example, the product is a tungsten steel part), the first turntable of the utility model must be a transparent glass turntable, but the glass turntable is easy to wear, so only the bottom surface of the product is inspected at the first turntable to reduce the contact time between the product and the first turntable; then the inspection of other surfaces and angles is completed at the second turntable, and the second turntable is a metal turntable, which is relatively not easy to wear, and the use of a metal turntable (because it is opaque) has low requirements on the light source of the visual inspection device. The combination of the two turntables can not only meet the needs of product inspection, but also do not need to replace the turntable frequently, thereby reducing the work of repairing and replacing the turntable.

A vibrating feeding mechanism 4 is arranged upstream of the first rotating disk, and a feeding end of the vibrating feeding mechanism is connected to a disk surface of the first rotating disk.

[0036] The first turntable is a transparent glass turntable, and a first visual inspection device 21 for inspecting the product from below is provided on the first turntable. The first visual inspection device is provided on the machine platform and is located directly below the first turntable;

[0037] The second turntable is a metal turntable, and is provided with a plurality of second visual inspection devices 31 for inspecting the product from above and a plurality of third visual inspection devices 32 for inspecting the product from the side, and the second visual inspection devices and the third visual inspection devices are arranged on the machine platform;

[0038] The first turntable and the second turntable are butt-jointed, and a material guiding structure 5 is provided at the joint between the two, through which the product is guided from the first turntable to the second turntable.

[0039] In this embodiment, the vibrating feeding mechanism is a vibrating disc feeding mechanism. This is a prior art, so it will not be described in detail.

[0040] The vibrating feeding mechanisms are provided with two, but not limited to this, one is also acceptable, and two are provided to meet the feeding and detection rhythm of the present embodiment.

[0041] In this embodiment, a first lower bin 22 is provided around the first turntable, and a first blowing nozzle is provided at the center of the first turntable. The first blowing nozzle 23 is aimed at the first bin, and defective products are blown into the first bin through the first blowing nozzle.

[0042] In this embodiment, Figure 5 and Figure 6 As shown, the material guide structure 5 includes a first material guide component 51 and a second material guide component 52, the first material guide component includes a first material guide frame and an arc-shaped first material guide piece installed on the first material guide frame, the height of the first material guide frame and the position of the first material guide piece from the center of the first turntable can be adjusted; the first material guide piece is bent toward the direction of the first turntable;

[0043] like Figure 5 and Figure 6 As shown, the second material guide assembly 52 includes a second material guide frame 521 and a second guide sheet 522 and a third guide sheet 523 installed on the second material guide frame, the height of the second material guide frame and the position of the third guide sheet from the center of the second turntable can be adjusted; the second guide sheet and the third guide sheet are both bent toward the direction of the second turntable, and the second guide sheet is located on the inner side of the third guide sheet. In this embodiment, the curvature of the second guide sheet and the third guide sheet is basically consistent with the curvature of the second turntable.

[0044] In this embodiment, Figure 5 and Figure 6 As shown, the material guide structure 5 also includes a third material guide component 53, and the third material guide component includes a third material guide frame 531 and a fourth material guide sheet 532. The height of the fourth material guide sheet and the position from the center of the second turntable of the third material guide frame can be adjusted, and the fourth material guide sheet is in the shape of a flat plate.

[0045] In this embodiment, the first guide sheet gradually deviates toward the edge of the first turntable along the rotation direction; the second guide sheet and the third guide sheet gradually deviate toward the inner side of the second turntable along the rotation direction. Only with such a design can the product be smoothly moved from the first turntable to the second turntable.

[0046] Working principle and process of the material guide structure:

[0047] like Figure 5 As shown, the rotation direction of the first turntable and the second turntable is shown in the figure. When the product rotates to the first guide sheet, the first guide sheet slowly guides the product to its left side, and then slowly enters between the second guide sheet and the third guide sheet. If some individual products are not in the proper position after the above process, the fourth guide sheet plays an auxiliary role and blocks the product from the outside to ensure that the products after passing through the guide structure are in the proper position and rotate with the second turntable.

[0050] In this embodiment, the circumference of the first turntable is smaller than the circumference of the second turntable, and the size relationship between the two is designed according to the number of visual inspection devices in order to match the production rhythm of the two.

[0051] The working principle and working process of the utility model are as follows:

[0052] The product is conveyed to the first turntable through the vibrating feeding mechanism, and the product rotates with the first turntable. Since the first turntable is a transparent glass turntable, the bottom surface of the product is inspected from below by the first visual inspection device. If it is a defective product, when the first turntable drives the product to rotate to the first discharge bin, the defective product is blown into the first bin through the first blowing nozzle; if it is a qualified product, it continues to rotate with the first turntable, and the product is guided to the second turntable through the material guide structure. Then, during the rotation of the second turntable, the top and sides of the product are visually inspected by multiple second inspection devices and multiple third inspection devices. According to the inspection data recorded in the control system, the product is blown into the corresponding (such as qualified products, different defect types) second discharge bin through the second blowing nozzle to distinguish the discharge.
