[0023] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.
[0024] In the description of this application, the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limiting this application.
[0025] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "install", "connect" and "connect" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, a conflicting connection or an integrated connection. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0026] In order to facilitate understanding of the solution provided by the embodiment of the present application, a brief introduction to some of the terms involved in the solution is first given.
[0027] AOI (Automatic Optical Inspection) cameras are advanced visual devices used in industrial automated inspections, primarily for non-contact, real-time quality monitoring of products on the production line. Using high-resolution imaging technology and advanced image processing algorithms, AOI cameras can quickly and accurately identify defects or anomalies on products.
[0028] Optical machine: In this solution, this refers to a DLP (Digital Light Processing) optical processing device that produces a uniform and stable light source with a changing pattern. It works in conjunction with the camera to achieve high-quality 3D reconstruction. Specifically, the "optical machine" here can be understood as an integrated device comprising the lighting system and imaging system, which assists in capturing 3D information about an object.
[0029] Figure 1 A schematic diagram of a camera and optical machine installation provided in an embodiment of the present application.
[0030] like Figure 1As shown, the AOI inspection camera includes a camera frame, a camera, and an optical engine 101. The camera frame has a hollowed-out center for supporting and securing the camera, as well as for securing the optical engine 101. The camera is fixed to the hollowed-out center of the camera frame for real-time imaging of objects. The optical engine 101 is fixed to the side of the camera frame to assist the camera in capturing three-dimensional information about the object. The rational arrangement of the camera frame, camera, and optical engine 101 forms the AOI inspection camera, enabling automatic optical inspection of objects.
[0031] For further reference Figure 2 To help understand the specific structure of the camera rack, the camera rack includes at least three columns 201, a support top plate 204, a support middle plate 202, and a fixed seat 206. The support top plate 204 and the support middle plate 202 are placed horizontally, the center positions of the support top plate 204 and the support middle plate 202 are hollowed out, and the edge positions are fixedly connected to the column 201. The fixed seat 206 is fixedly connected to the support top plate 204 and the support middle plate 202 respectively through two connecting cross bars 205, and the fixed seat 206 is located on the side of the column 201. Among them, the fixed seat 206 is used for the installation and positioning of the AOI inspection camera, the camera rack is used to fix and support the camera, and to fix the optical machine 101, and the support middle plate 202 has edges. It is worth noting that the fixed seat 206 can be fixed to a point on an object, and the object can be production equipment, a gantry, a sliding guide rail, a wall, a ceiling, a movable bracket or a mechanical vehicle, etc. The AOI inspection camera can perform shooting operations at the point where the fixed seat 206 is fixed.
[0032] The camera includes a camera body 108 and a telecentric lens 107. The camera is located in the center of the camera frame and is secured by a support top plate 204. The camera body 108 is used to capture light transmitted through the lens and convert it into a digital signal. The telecentric lens 107 is used to form an image, ensuring consistent image magnification and clarity at different object distances.
[0033] The optical engine 101 is fixedly connected to the edge of the supporting middle plate 202 in the camera frame. There is at least one optical engine 101, and it is used for 3D modeling and reconstruction.
[0034] It can be seen from the implementation shown in this example that the AOI inspection camera is fixed to a point on an object through a side fixing seat, and can remain stable during operation or movement to ensure the accuracy of the camera and optical machine during use and reduce debugging time. Setting the camera at the center hollow position of the column and the support plate can reduce the volume of the entire machine, and setting the optical machine at the edge position of the supporting middle plate makes the optical machine setting compact and orderly, which can further reduce the volume of the entire machine.
[0035] In one example, the columns 201 and the supporting top plate 204 and the supporting middle plate 202 can be fixedly connected by screw threads. Figure 2 , there are threaded holes at the connection between the support top plate 204 and the column 201 (refer to Figure 2 The circular hole on the upper surface of the middle support top plate 204) can be used to fix the support top plate 204 and the column 201 by screws. In addition, there is a limit on the column 201 below the position of the support middle plate 202. Figure 2 Not shown, but in Figure 2 It can be seen that the column 201 below the supporting middle plate 202 is thicker than the column 201 above it. The diameter difference between the upper and lower parts of the column 201 can form a limit. The surface of the column 201 above the supporting middle plate 202 is threaded, and the supporting middle plate 202 can be locked and fixed at the limit position of the column 201 by the nut 203.
[0036] In one example, reference Figure 3 One of the connecting cross bars 205 is fixedly connected to the lower surface of the supporting top plate 204 , and the other connecting cross bar 205 is fixedly connected to the upper surface of the supporting middle plate 202 .
[0037] It is easy to understand that the connection method described in the above embodiment enables the contact area between the connecting cross bar 205 and the supporting top plate 204 and the supporting middle plate 202 to be larger. The larger the contact area, the more uniform the force distribution, which means that the connection between the objects is more stable.
[0038] In another example, continue to refer to Figure 3 The two connecting cross bars 205 are respectively connected to the support top plate 204 and the support middle plate 202 by screw thread. Specifically, the connection between the connecting cross bars 205 and the support top plate 204 and the support middle plate 202 is provided with a threaded hole (in Figure 3 In the figure, the connecting crossbar 205 is fixed by screws, or fixed by a combination of bolts and nuts. In addition, the connecting crossbar 205 is provided with a notch that matches the column 201. The connecting crossbar 205 is engaged with the column 201 through the notch to increase the overall stability. In another example, back to Figure 2 The connection between the fixed seat upright and the connecting cross bar 205 is provided with a threaded hole, which can be fixed by screws, or fixed by a combination of bolts and nuts.
[0039] In the embodiment of this example, the fixing seat 206 is indirectly fixed to the lower surface of the supporting top plate, the upper surface of the supporting middle plate and the column through the connecting cross bar 205 to increase the overall stability of the camera rack.
[0040] In one example, returning to Figure 1The optical engine 101 can be fixedly connected to the edge of the supporting middle plate 202 through the optical engine bracket. The fixed connection method can be threaded connection, clamping connection, or riveting, which is not limited here. The optical engine bracket and the optical engine 101 are connected by a rotating shaft, so that the angle of the optical engine 101 can be adjusted during use.
[0041] In the implementation mode of this example, the optical machine is connected to the supporting middle plate through the optical machine bracket, which can keep the optical machine stable during use. The optical machine and the optical machine bracket are connected through a rotating shaft, which can enable the optical machine to adjust the angle in a certain direction, thereby making the imaging surface of the optical machine coincide with the imaging surface of the telecentric lens, and ensuring that the depth of field of the lens is within the specified range.
[0042] In one example, continue with reference Figure 1 The camera also includes a lens adapter plate 103, which is fixed to the support top plate 204 (the lens adapter plate 103 covers the support top plate 204, so the support top plate 204 is Figure 1 (not shown in the top view), the lens adapter plate 103 is used to align the center position of the telecentric lens 107. A through hole, adapted to the size of the telecentric lens 107, is located at the center of the lens adapter plate 103. The telecentric lens 107 passes through this through hole, and the position of the through hole can be adjusted to the correct position of the telecentric lens 107.
[0043] In another example, continue to refer to Figure 1 The camera also includes a lens locking member 109 for securing the telecentric lens 107. The bottom of the lens locking member 109 is fixed to the lens adapter plate 103, and the telecentric lens 107 passes through the center of the lens locking member 109. The lens locking member 109 has a slit on one side, and by locking the slit, the telecentric lens 107 is locked. It is easy to understand that the lens locking member 109 is fixed to the lens adapter plate 103, which is in turn fixed to the support top plate 204, thereby maintaining a stable connection between the telecentric lens 107 and the camera frame as a whole.
[0044] It is worth noting that the lens locking member 109 and the lens adapter plate 103 can be connected by threads. For example, the connecting holes of the lens locking member 109 and the lens adapter plate 103 are both provided with threads, and screws can be drilled into the threaded holes to secure the two. Alternatively, bolts can be placed in the connecting holes of the lens locking member 109 and the lens adapter plate 103, and then the two can be fastened together using nuts. The slit of the lens locking member 109 can be locked with screws, riveted, clamped, or other methods, without limitation.
[0045] By providing a lens locking member to lock the telecentric lens, the telecentric lens can be further kept stable on the entire camera frame.
[0046] In another example, continue to refer to Figure 1 The camera further includes a camera auxiliary bracket 104 , the bottom of which is fixed to the lens adapter plate 103 , and one side of the camera body 108 is fixed to the auxiliary bracket 104 .
[0047] It is worth noting that the bottom of the camera auxiliary bracket 104 is L-shaped and is secured to the lens adapter plate 103 via a threaded connection. For example, the two can be locked together using screws, bolts, or nuts, without limitation. The camera body 108 and the auxiliary bracket 104 can be secured together via a snap-fit connection, whereby a slot is provided on one side of the camera body 108, and the auxiliary bracket 104 is inserted into the slot on the side of the camera body 108, thereby securing the camera body 108. Alternatively, the camera body 108 and the auxiliary bracket 104 can be secured together via a threaded connection, whereby the two can be locked together using screws, bolts, or nuts. Furthermore, after the camera body 108 and the auxiliary bracket 104 are secured together via a snap-fit connection, they can be further secured together using a threaded connection, without limitation in this embodiment.
[0048] By fixing a camera auxiliary bracket on the lens adapter plate and then fixing the camera body to the camera auxiliary bracket, the camera body can be kept stable and not easily rotated.
[0049] In one example, reference Figure 4 The camera rack also includes a supporting base plate 306, which is fixedly connected to the column 201, and an auxiliary camera 301 and a fill light 303 are arranged on the supporting base plate.
[0050] It is worth noting that the support base plate 306 and the column 201 can be fixedly connected by threads. There are threaded holes at the connection between the support base plate 306 and the column 201, and the support base plate 306 and the column 201 can be locked and fixed by screws.
[0051] The purpose of the auxiliary camera is to enhance the function of the main camera or provide additional information support, thereby improving the performance and accuracy of the overall inspection system. The fill light can improve the camera's inspection accuracy and speed through illumination.
[0052] In another example, continue to refer to Figure 4The auxiliary camera 301 and fill light 303 can be connected to the support base 306 via a movable bracket. The movable bracket includes a fill light bracket 304 and an auxiliary camera bracket 302. The auxiliary camera 301 and the auxiliary camera bracket 302 are connected by a hinge. The auxiliary camera bracket 302 is fixedly connected to the support base 306, and the angle of the auxiliary camera 301 can be adjusted via the hinge. Similarly, the fill light 303 and the fill light bracket 304 are connected by a hinge. The fill light bracket 304 is fixedly connected to the support base 306, and the angle of the fill light 303 can be adjusted via the hinge.
[0053] The auxiliary camera and the auxiliary camera bracket are connected through a rotating shaft, which can obtain shooting angles at different angles. Similarly, the fill light and the fill light bracket are connected through a rotating shaft, which can help illuminate the subject at different angles.
[0054] In another example, continue to refer to Figure 4 A light shield 305 is provided in the middle of the supporting base plate 306, and the light shield 305 is used to prevent the light of the fill light from propagating upward.
[0055] The fill light can illuminate the object being photographed and improve the image quality, but the light from the fill light propagates upward to the lens, which will affect the lens and cause adverse effects such as glare and overexposure. By setting a lens hood, the interference of external light sources and the influence of stray light can be reduced, thereby indirectly improving the image quality.
[0056] In one example, reference Figure 5 The camera frame is also provided with an outer cover, which includes: an annular outer cover 402, an arc-shaped outer cover 403, and a camera outer cover 401. The annular outer cover 402 and the arc-shaped outer cover 403 are provided with a clamping edge, and a groove is provided on the fixed seat rod. The clamping edge and the groove form a limit, and the arc-shaped outer cover 403 is clamped with the annular outer cover 402 at the position of the fixed seat rod groove. The camera cover 401 covers the camera body 108, and the bottom of the camera cover 401 is fixed to the upper part of the annular outer cover 402. The state after the cover is installed can be referred to Figure 6 .
[0057] In another example, continue to refer to Figure 5 The bottom of the annular outer cover 402 is provided with a stepped protrusion, and the supporting base plate 306 is provided with a groove matching the above-mentioned stepped protrusion. The annular outer cover 402 can be fixed to the supporting base plate 306 through the stepped protrusion and the groove.
[0058] In another example, continue to refer to Figure 5 The surface of the annular outer cover is provided with heat dissipation holes, and a filter is provided at the position of the heat dissipation holes. The heat dissipation holes are used for heat dissipation, and the filter is used for dust prevention.
[0059] An outer cover is set on the outside of the camera frame to shield the internal equipment, which not only has a visually beautiful effect but also has a dust-proof effect. In addition, heat dissipation holes and filters are set on the surface of the outer cover, which can not only prevent dust from the internal equipment but also have a certain heat dissipation effect.
[0060] In one example, returning to Figure 1 The support top plate 204 is provided with a wire duct 106 on its periphery. The wire duct 106 is fixedly connected to the support top plate 204 and is used to guide the wires of electrical appliances to avoid clutter. The electrical appliances include one or more of the camera 108, the optical engine 101, the auxiliary camera 301, and the fill light 303.
[0061] It is worth noting that the wire duct 106 can be a standard plastic flexible keel wire duct, which has good bending properties and can adapt to the complex curved wiring path of the support top plate 204. The wire duct is used to guide the leads of electrical appliances to avoid tangling the leads during the movement or disassembly of the camera.
[0062] In one example, continue with reference Figure 1 A circuit interface board 105 is also provided on the periphery of the support top plate 204. The circuit interface board 105 is fixedly connected to the support top plate 204. The circuit interface board 105 is used to connect the wires guided through the wire trough 106. The circuit interface board 105 serves as a power distribution unit, safely distributing the main power to various electrical devices through the wires.
