Description

Technical Field

[0001] The present invention relates to the technical field related to POL laser processing, and in particular to a POL laser cutting adaptive rotating AOI device. Background Art

[0002] Currently, the AOI devices used for POL laser cutting on the market can be divided into two types according to the light source used: fixed surface light source and follow-up light source AOI devices. The AOI devices used for POL laser cutting need to work with the adaptive scaling platform of POL cutting. The above two methods have the following problems:

[0003] 1. The fixed surface light source AOI device needs to install the surface light source just below the product inspection side (backlight source), which is mainly used to detect the situation where the POL cutting point is outside the glass range (abbreviated as: external cutting); when the POL cutting point is within the glass range (abbreviated as: internal cutting), the light source needs to be illuminated obliquely upward, which will interfere with the platform residual material clamping claws. At this time, the glass needs to be moved to a special platform or equipment for inspection. The fixed surface light source AOI device cannot be compatible with both internal and external cutting of products on the same platform, which is not conducive to equipment cost reduction and structural optimization.

[0004] 2. The follow-up light source AOI device fixes the light source to the AOI camera, moves with the camera, and adjusts the lighting direction according to the inspection path. When the light source is oriented diagonally upward, it is mainly used for internal inspection of the product. When the light source is adjusted to directly below the inspection edge, it is mainly used for external inspection of the product. The problem is that the light source is located below the glass surface, and the platform cannot be equipped with a clamp. The follow-up light source AOI device can only be used as a standalone inspection device or workstation, and is not compatible with the adaptive scaling platform used for POL cutting, which is not conducive to equipment cost reduction and structural optimization.

[0005] In view of the above-mentioned defects, the designers have actively carried out research and innovation in order to create a POL laser cutting adaptive rotating AOI device to make it more valuable for industrial use. Summary of the Invention

[0013] As a further improvement of the present invention, a bearing cover plate is installed on the bearing base outside the top of the bearing.

[0014] As a further improvement of the present invention, the adjustment assembly includes a first light source adjustment member and a second light source adjustment member, the top of the second light source adjustment member is connected to the rotating shaft core above, and the number of first light source adjustment members is two and they are respectively installed on both sides of the second light source adjustment member along the X-axis direction.

[0015] As a further improvement of the present invention, a strip light source is installed between the two first light source adjustment members.

[0016] By means of the above solution, the present invention has at least the following advantages:

[0017] 1. The present invention uses a rotating bar light source in conjunction with the backlight source of the adaptive scaling platform for POL cutting to meet the lighting requirements of the product's POL internal and external cutting, making the processing and inspection of POL internal and external cutting compatible with the same equipment, reducing equipment costs, simplifying equipment structure, facilitating maintenance, and improving compatibility;

[0042] Example

[0043] like Figures 1 to 4 As shown,

[0044] A POL laser cutting adaptive rotating AOI device includes a substrate 1, an AOI component and a rotating light source component, wherein the AOI component and the rotating light source component are both mounted on the substrate 1;

[0045] The AOI assembly includes an image fixing base plate 2, an image connecting plate 3, and a camera 24. The image fixing base plate 2 is mounted on the base plate 1, and the image connecting plate 3 is mounted on the image fixing base plate 2. An image adjustment one-dimensional slide 5 is provided on one side of the image connecting plate 3 along the positive direction of the X-axis. The image adjustment one-dimensional slide 5 can drive a fixed adapter plate 6 along the positive direction of the X-axis to move along the Z-axis. The camera lens 13 at the bottom of the camera 24 is mounted on the side of the fixed adapter plate 6 along the positive direction of the X-axis through a lens fixing member 23.

[0046] The rotating light source assembly includes a rotating connecting plate 4, a servo motor 7, a motor mounting seat 8, a strip light source 14, a bearing base 18 and a rotating shaft core 20. The rotating connecting plate 4 is installed on the base plate 1 near the bottom, and the motor mounting seat 8 and the bearing base 18 are installed in sequence on the rotating connecting plate 4 near the bottom along the positive direction of the X-axis. The image connecting plate 3 is located in the middle position between the motor mounting seat 8 and the bearing base 18. The servo motor 7 is installed on the motor mounting seat 8. The outer side of the rotating shaft core 20 is installed on the inner side of the bearing base 18 through the bearing 17. The output shaft at the bottom of the servo motor 7 is connected to the rotating shaft core 20 through the active synchronous pulley 9, the synchronous belt 10 and the driven synchronous pulley 11 in sequence. The rotating shaft core 20 is connected to the strip light source 14 located below the bearing base 18 through an adjusting assembly. The camera lens 13 can pass through the inner hole of the rotating shaft core 20 along the Z-axis direction and extend to the bottom of the bearing base 18.

[0047] The image adjustment one-dimensional slide 5 can be a conventional one-dimensional driving mechanism such as an electric slide.

[0048] Preferably, a sensor sheet 21 is installed on the portion of the rotating shaft core 20 protruding from the bearing base 18 , and a photoelectric sensor 22 adapted to the sensor sheet 21 is provided on the rotating connecting plate 4 above the bearing base 18 .

[0049] Preferably, a camera protective cover 25 is provided on the outside of the camera 24, and the camera protective cover 25 is installed on the image connecting plate 3. A belt protective cover 26 is provided on the outside of the active synchronous pulley 9, the synchronous belt 10 and the driven synchronous pulley 11, and the belt protective cover 26 is installed on the motor mounting seat 8 and the bearing base 18.

[0050] Preferably, a bearing cover plate 19 is installed on the bearing base 18 on the outer side of the top of the bearing 17.

[0051] Preferably, the adjustment assembly includes a first light source adjustment member 15 and a second light source adjustment member 16, the top of the second light source adjustment member 16 is connected to the rotating shaft core 20 above, there are two first light source adjustment members 15 and they are respectively installed on both sides of the second light source adjustment member 16 along the X-axis direction, and a strip light source 14 is installed between the two first light source adjustment members 15.

[0052] The technical solution of the present invention is an optimization of the fixed surface light source AOI device and the follow-up light source AOI device. It uses a short strip light source to illuminate obliquely downward and move with the camera. The lighting direction is adjusted according to the detection path. At the same time, the processing platform is equipped with a surface light source (abbreviated as: backlight source) directly below the detection edge. It mainly solves the following problems:

[0053] 1. Compared with the fixed surface light source AOI device, the present invention is compatible with the internal and external cutting detection of the product, does not require separate detection equipment or workstations, shortens the detection time, improves work efficiency, and reduces equipment costs.

[0054] 2. Compared with the follow-up light source AOI device, the present invention is fully compatible with the adaptive scaling platform of POL cutting. There is no need to make the AOI device into an independent device or workstation, which shortens the inspection time, improves work efficiency, reduces equipment costs, and optimizes the equipment structure.

[0055] like Figure 1 As shown, the present invention mainly consists of two parts: an AOI assembly and a rotating light source assembly. The camera 24 and the camera lens 13 form a camera assembly that passes through the middle of the rotating shaft core 20 and is used to detect the product below. The strip light source 14 is installed on the rotating shaft core 20 through the light source adjustment member 15 and the light source adjustment member 2 16 to obtain the freedom of rotation around the camera lens 13, and the angle of the rotating lighting is controlled by the power system composed of the servo motor 7, the active synchronous pulley 9, the synchronous belt 10, and the driven synchronous pulley 11. The camera 24 and the camera lens 13 form a camera assembly. In combination with the strip light source 14, it can detect the internal cut of the product, and in combination with the platform backlight 28, it can detect the external cut of the product, thereby achieving compatibility with the internal and external cut detection of the AOI device.

[0056] like Figure 2 As shown, the AOI assembly consists of an image-fixing base plate 2, an image connection plate 3, a one-dimensional image adjustment slide 5, a fixed adapter plate 6, a camera lens 13, a lens fixing member 23, a camera 24, and a camera protective cover 25. The camera assembly is fixed to the fixed adapter plate 6 by the lens fixing member 23, which facilitates adjustment of the camera assembly's shooting direction and working height. The one-dimensional image adjustment slide 5 is used to fine-tune the camera assembly's working height to ensure image clarity. The camera protective cover 25 protects the internal camera assembly for stable operation.

[0057] like Figure 3As shown, the rotating light source assembly consists of a rotating connecting plate 4, a servo motor 7, a motor mounting seat 8, an active synchronous pulley 9, a synchronous belt 10, a driven synchronous pulley 11, a rotating shaft locking nut 12, a strip light source 14, a light source adjustment part 15, a light source adjustment part 2 16, a bearing 17, a bearing base 18, a bearing cover plate 19, a rotating shaft core 20, a sensor sheet 21, a photoelectric sensor 22, a belt protection cover 26, and a limit shaft ring 27.

[0058] The rotating connecting plate 4 is fixed to the base plate 1 using slots, which facilitates the adjustment of the height of the rotating light source assembly relative to the product within a certain range; the rotating shaft core 20 is installed in the bearing base 18 through the bearing 17, and the bearing 17 is pressed by the bearing cover plate 19, so that the rotating shaft core 20 obtains the rotational freedom relative to the bearing base 18; the rotating shaft locking nut 12 presses the driven synchronous pulley 11, the bearing 17 and the limit shaft ring 27 onto the rotating shaft core 20, ensuring that the relative position of the driven synchronous pulley 11 remains unchanged, and together with the servo motor 7, the active synchronous pulley 9 and the synchronous belt 10, constitutes a motion system that drives the rotating shaft core 20 to rotate.

[0059] The strip light source 14 is installed on the rotating shaft locking nut 12 through the light source adjustment part 15 and the light source adjustment part 2 16, so that the strip light source 14 can rotate synchronously with the rotating shaft core 20, thereby realizing that the strip light source 14 automatically adjusts the lighting direction and lighting angle along the detection path during the detection process to ensure the detection effect.

[0060] The sensor sheet 21 is fixed to the top end face of the rotating shaft core 20, and together with the photoelectric sensor 22, it forms a feedback system that limits the rotation range of the rotating shaft core 20, prevents the strip light source 14 from rotating excessively, and determines the position of the light source; the servo motor 7 adjusts the distance between the active synchronous pulley 9 and the driven synchronous pulley 11 through the slot on the motor mounting seat 8, thereby adjusting the tightness of the synchronous belt 10 to prevent the synchronous belt from wearing or slipping due to being too tight or too loose.

[0061] The belt protection cover 26 is installed on the motor mounting seat 8 and the bearing base 18, and covers the driving synchronous pulley 9, the synchronous belt 10, and the driven synchronous pulley 11, so as to prevent the dust generated by the friction of the belt from contaminating the product and prevent foreign objects or human bodies from being drawn into the belt and causing danger.

[0062] Adaptive scaling platform with platform backlight source cut along with POL (such as Figure 4 ) movement, always keeping the detection edge within the light source. The relevant content of the adaptive scaling platform for POL cutting has been previously disclosed in Patent 1, Publication No. "CN215393287U," entitled "Adaptive Scaling Platform for Multi-Sized POL Laser Cutting." The backlight source portion of the platform is the light source module 5 in Patent 1.

[0063] Brief description of the working process of the present invention:

[0064] The present invention's adaptive rotating AOI device for POL laser cutting moves along the product's cutting path. The AOI component photographs and inspects the POL cut edge. The strip light source 14 automatically rotates to a position parallel to or at a predetermined angle to the cutting path based on the cutting path and inspection requirements, ensuring optimal lighting results. The rotation angle of the strip light source 14 can be calculated using the tooth ratio of the driving synchronous pulley 90 to the driven synchronous pulley 11: The number of teeth on the driving synchronous pulley 9: the number of teeth on the driven synchronous pulley 11 = the rotation angle of the strip light source 14: the rotation angle of the output shaft of the servo motor 7.
