Description

TECHNICAL FIELD

[0001] The present disclosure relates to a detection device, in particular to an optical detection frame device. BACKGROUND

[0002] In the prior art, optical measurement is performed by using coded reference points to identify points for associating a picture and a point cloud of a piece to be detected together. Typically, the coded reference points are directly pasted on the piece to be detected, and then optical scanning is performed to form a picture to complete the optical measurement. Taking a vehicle as an example of the piece to be detected, there are usually 100-200 coded reference points, and it takes about 30 minutes for two operators to install and uninstall these coded reference points, which is time-consuming and laborious. Moreover, there is a risk of hitting the head of the operator when the operator installs and uninstalls the coded reference points close to the bottom of the vehicle. CONTENT OF THE UTILITY MODEL

[0003] In order to solve the above technical problems, the present disclosure provides an optical detection frame device, which aims to perform optical measurement on the same or similar type of pieces to be detected by means of pasting coded reference points directly onto a detection frame of the optical detection frame device.

[0004] In one aspect, the present disclosure provides an optical detection frame device. The optical detection frame device comprises a detection frame and a plurality of coded reference points. The detection frame has a spatial configuration conforming to the outer contour of a piece to be detected. The plurality of coded reference points are arranged on the detection frame at positions corresponding to scanning feature points of the piece to be detected.

[0005] Thus, the optical detection frame device according to the present disclosure has a compact structure, can provide simple and reusable optical detection reference points, and can also make the detection of the same or similar type of pieces to be detected consistent and accurate, and has good scalability or applicability.

[0006] In one or more embodiments, the detection frame is composed of metal profiles. The detection frame comprises a plurality of aluminum alloy profiles, adjacent aluminum alloy profiles are connected to each other, in particular through connecting pieces, to form the spatial configuration. The plurality of coded reference points are pasted on the side of the aluminum alloy profiles facing the piece to be detected. The detection frame comprises a left frame portion and a right frame portion connected by transverse aluminum alloy profiles.

[0007] Thus, by connecting a plurality of aluminum alloy profiles, a light and stable spatial configuration of the detection frame conforming to the outer contour of the piece to be detected can be obtained.

[0008] In one or more embodiments, the detection frame is provided with a plurality of avoidance beams that are quickly detachable from the main body of the detection frame, to allow the optical detection frame device to be moved into a detection position relative to the piece to be detected. In the detection position, the optical detection frame device wraps around the piece to be detected.

[0009] Thus, the avoidance beams provide lateral stability to the spatial configuration of the detection frame when in the connected state. The avoidance beams can provide a passable space to allow the optical detection frame device to move into its detection frame to enclose the detection table and the piece to be detected thereon when in the disassembled state.

[0010] In one or more embodiments, the plurality of avoidance beams are carbon fiber rods coupled to the left and right frame portions of the detection frame in the lateral direction.

[0011] Thus, the avoidance beams in the form of carbon fiber rods are lightweight and provide sufficient lateral stability to the detection frame.

[0012] In one or more embodiments, the optical detection frame device further comprises a U-shaped base to which the detection frame is fixed. The U-shaped base comprises a lateral beam and a pair of longitudinal beams, the rear ends of which are connected to the lateral beam to form a U-shaped configuration. The optical detection frame device further comprises a plurality of traveling wheels disposed below the U-shaped base. The piece to be detected is a vehicle.

[0013] Thus, the U-shaped base allows the optical detection frame device to move unobstructed to the detection position to enclose the detection table and the piece to be detected thereon. The traveling wheels facilitate the movement of the optical detection frame device to any desired position.

[0014] In one or more embodiments, the optical detection frame device is configured to be guided by a guide rail assembly. The guide rail assembly comprises a pair of guide rails fixed on both sides of the detection table for guiding the positioning of the optical detection frame device relative to the detection table for carrying the piece to be detected. Each guide rail comprises an upwardly inclined guide rail lead-in section and a subsequent horizontal guide rail body section.

[0015] Thus, the guide rail assembly guides the smooth movement of the optical detection frame device on the guide rails to the detection position.

[0016] In one or more embodiments, the optical detection frame device comprises a plurality of Z-direction support wheels and / or a plurality of Y-direction positioning wheels mounted below the longitudinal beams of the U-shaped base. The Z-direction support wheels comprise rollers configured to be able to roll on the upper surface of the guide rail body section. Each of the Y-direction positioning wheels comprises a pair of guide wheels able to roll on the opposite side surfaces of the guide rail.

[0017] The Z-direction support wheels can facilitate the smooth movement of the optical detection frame device to the detection position and provide vertical support to the U-shaped base and the detection frame. The Y-direction positioning wheels can provide guiding and limiting functions to limit the movement of the optical detection frame device along the guide rails. The combined use of the Y-direction positioning wheels and the Z-direction support wheels can ensure the stable and smooth movement of the optical detection frame device along the guide rails to the detection position.

[0018] In one or more embodiments, the optical detection frame device is configured to be positioned by a stopper assembly. The stopper assembly is disposed near the distal end of the rail body segment distal from the rail introduction segment for defining a stop position of the optical detection frame device on the rail. The stopper assembly includes an inverted T-shaped support and a stop portion for preventing movement of the optical detection frame device. The inverted T-shaped support includes a fixed base and an upright portion perpendicular to the base. The upright portion has a side facing the rail body segment provided with the stop portion configured to abut against a front end surface of a front end portion of the longitudinal beam of the U-shaped base.

[0019] Thus, the stopper assembly can define a stop position of the optical detection frame device on the rail.

[0020] In one or more embodiments, the optical detection frame device is configured to be locked in the detection position by a locking assembly disposed near the outside of the stopper assembly. The locking assembly includes a fixed base, a first locking component disposed on an upper surface of the base, and a second locking component disposed on an upper surface of the U-shaped base. The first and second locking components are used in cooperation to lock the optical detection frame device in position.

[0021] Thus, the locking assembly can lock the optical detection frame device in position on the rail.

[0022] In one or more embodiments, the locking assembly further includes an adjustment member extending through a vertical portion of the base. The extension amount of the adjustment member extending through the vertical portion is adjustable to further adjust the detection position of the optical detection frame device.

[0023] Thus, the adjustment member can fine-tune the detection position of the optical detection frame device. BRIEF DESCRIPTION OF DRAWINGS

For those skilled in the art, the specific meaning of the above terms in the embodiments of the present disclosure can be understood according to the specific circumstances.

[0047] In view of the time-consuming and laborious optical measurement by directly pasting the coded reference points on the detected piece, the present disclosure proposes an optical detection frame device for facilitating auxiliary optical measurement.

[0048] The basic idea of the optical detection frame device according to the present disclosure is that the detection frame has a spatial configuration corresponding to the outer contour of the detected piece, and by setting a plurality of coded detection points on the detection frame of the optical detection frame device instead of directly pasting on the vehicle to be detected, a simple optical measurement reference point is provided for the vehicle. This can save the time required for mounting and dismounting the coded reference points on the vehicle each time, and also ensures the consistency and accuracy of the detection of the same or similar type of vehicle using it.

[0049] The optical detection frame device according to the present disclosure will be described below with reference to the accompanying drawings, taking a vehicle as an example of the detected piece.

[0050] Reference Figure 1 A perspective view of the optical detection frame device according to the present disclosure is shown. The optical detection frame device 1 can include a detection frame 10 and a plurality of coded reference points P (only schematically indicated). The coded reference points P can be coded reference points commonly used in the prior art. The detection frame 10 has a spatial configuration corresponding to the outer contour of the detected piece 2. In other words, the inner contour of the detection frame can correspond to, in particular at least substantially correspond to, the outer contour of the detected piece, so that the detection frame 10 can be compactly configured. The detected piece 2 can be placed on a detection table 3 for detection. In other words, the spatial configuration of the detection frame 10 nests the outer contour of the detected piece 2 (see Figure 12 ). The detected piece 2 can be a vehicle, in particular a passenger car. The vehicle can be a vehicle of a certain model, or a vehicle of a similar model. The detected piece can be other objects, such as a body-in-white or a powertrain system. The positions of the plurality of coded reference points P set (e.g., pasted) on the detection frame correspond to the scanning feature points of the detected piece 2, and thus can be used as optical detection reference points of the detected piece 2. In particular, the plurality of coded reference points P on the detection frame 10 are equidistantly arranged outwardly relative to the corresponding scanning feature points of the detected piece 2.

[0051] Since the detection frame 10 has a spatial configuration that conforms to the outer profile of the vehicle, pasting the coded reference points P to the detection frame and pasting the coded reference points directly to the vehicle can provide similar or identical reference effects for optical detection. Moreover, pasting the coded reference points to the detection frame can enable the coded reference points to be reused by the same or similar types of vehicles without the need to painstakingly paste and remove the coded reference points on each vehicle. Furthermore, since the coded reference points are accurately positioned on the detection frame, the detection consistency and accuracy for the same or similar types of vehicles are high. Furthermore, for other types of vehicles, it is only necessary to correspondingly extend the spatial configuration of the detection frame to conform to the outer profile of the other types of vehicles, and thus the expandability or applicability is strong.

[0052] The detection frame 10 can be composed of metal profiles. With reference to Figure 1 , the detection frame 10 can include a plurality of aluminum alloy profiles 12, adjacent aluminum alloy profiles are connected to each other, especially through connecting pieces 13, to form a spatial configuration. In this way, the detection frame 10 is light in weight and also facilitates assembly. In the spatial configuration, the detection frame 10 can include a main body having a left frame portion and a right frame portion, the left frame portion and the right frame portion are connected by transverse aluminum alloy profiles. A plurality of coded reference points P can be pasted to the side of the aluminum alloy profile facing the piece 2 to be detected. In one example, the cross section of the aluminum alloy profile can be 100X 100mm. In this way, it can be ensured that the detection frame 10 has sufficient rigidity so that the coded reference points P will not be displaced due to the deformation of the optical detection frame device 1. The connecting piece 13 can include a connecting plate and a T-shaped bolt. In particular, the connecting plate can include a conformal bent connecting plate to adapt to the connection needs of adjacent aluminum alloy profiles 12. Adjacent aluminum alloy profiles can be fixed together by inserting T-shaped bolts through the connecting plate and the aluminum alloy profile. In this way, by connecting a plurality of aluminum alloy profiles 12, a light and stable spatial configuration of the detection frame 10 that conforms to the outer profile of the piece 2 to be detected can be obtained. In short, the detection frame is light in weight and high in strength, and also facilitates assembly.

[0053] The detection frame 10 can be provided with a plurality of avoidance beams 14 that are quickly detachable from the main body of the detection frame, to allow the optical detection frame device 1 to be easily moved into a measurement position relative to the piece 2 to be detected. In the detection position, the optical detection frame device 1 wraps around the piece 2 to be detected (with reference to Figure 12 As shown in Figure 1 , the plurality of avoidance beams 14 are connected to the main body of the detection frame 10 in the transverse direction, specifically, coupled to the left frame portion and the right frame portion of the detection frame 10 in the transverse direction. The plurality of avoidance beams 14 includes four avoidance beams coupled to the detection frame 10 by quick-release connecting pieces 16. The number of the plurality of avoidance beams is not limited to four, and can be more or less as needed. The avoidance beams 14 can be carbon fiber rods to provide a light structure. In Figure 1In the example shown, two clearance beams 14 are detachably connected to a pair of front uprights of the detection frame 10 at the front of the frame 10, spaced apart along the Z direction. Another clearance beam 14 is detachably connected to the upper middle part of the detection frame 10. Yet another clearance beam 14 is detachably connected to the lower rear part of the detection frame 10. This allows the clearance beams 14 to provide lateral stability for the spatial structure of the detection frame 10 while remaining connected. When the optical detection frame device 1 is to be moved to the detection position on the detection table 3 to inspect the workpiece 2 on the detection table 3, the clearance beams 14 can be quickly removed to allow the optical detection frame device 1 to move so that its detection frame 10 surrounds the detection table 3 and the workpiece 2 on it, thereby assisting in optical measurement. After the optical detection frame device 1 is in the detection position, at least a portion of the clearance beams 14 are reconnected to provide lateral stability (see reference). Figure 12 ).

[0054] Figure 3 A perspective view of the U-shaped base of the optical detection frame device is shown. Figure 3 As shown, the U-shaped base 20 includes a transverse beam 22 forming the U-shape and a pair of longitudinal beams 24. The U-shaped base 20 may be made of steel to provide sufficient rigidity. The detection frame 10 may be fixed to the U-shaped base 20. Specifically, the detection frame 10 is detachably fixed to the upper surface of the U-shaped base 20 by fasteners. In this way, the U-shaped base 20 allows the optical detection frame device 1 to move unobstructed to the detection position to surround the detection table 3 and the workpiece 2 to be detected thereon. The optical detection frame device 1 may include a plurality of wheels (specifically, a pair of rear wheels 30 and a pair of front wheels 32) disposed below the U-shaped base 20 to facilitate moving the optical detection frame device 1 to any desired position (e.g., the detection position).

[0055] Specifically, the rear ends of a pair of longitudinal beams 24 are connected to the transverse beam 22, while the front ends are free ends. For example, the pair of longitudinal beams 24 are fixed perpendicularly to the front surface of the transverse beam 22 at a distance inward from the two free ends of the transverse beam 22. A rear traveling wheel 30 is provided on the lower surface of each of the two free ends of the transverse beam 22. A transverse member 26 is provided on the transverse outer side of the front end of the pair of longitudinal beams 24, and the front traveling wheel 32 is located below the transverse member 26. In this way, the arrangement of the rear traveling wheel 30 and the front traveling wheel 32 outside the U-shaped structure will not cause any interference to the movement of the optical inspection frame device 1 to the inspection table. The rear traveling wheel 30 and the front traveling wheel 32 can be lockable wheels.

[0056] The U-shaped base 20 can further include a plurality of stiffeners 28 to provide additional strength to the U-shaped base 20. In particular, the plurality of stiffeners 28 can be disposed between the rear portion of the longitudinal beams 24 and the free ends of the transverse beams 22, and / or between the front portion of the longitudinal beams 24 and the free ends of the cross member 26.

[0057] The optical detection frame device 1 is configured to be guided by a guide rail assembly 40 (see Figure 4 ). The guide rail assembly 40 includes a pair of guide rails 42 fixed on both sides of the detection table 3 (refer to Figure 4 and Figure 11 , the footprint of the detection table is schematically shown in a dashed box) for guiding the positioning of the optical detection frame device 1 relative to the detection table 3. Each guide rail 42 includes an upwardly inclined guide rail introduction section 421 (see Figure 5 , an enlarged view) and a subsequent horizontal guide rail body section 422. The guide rails 42 are fixed in place by a plurality of fasteners 44 on both sides of the detection table 3. Thereby, the guide rail assembly 40 guides the optical detection frame device 1 to move along the pair of guide rails 42 to a detection position on the detection table 3.

[0058] With reference to Figure 3 , the optical detection frame device 1 can further include a plurality of Z-direction support wheels 36 and / or a plurality of Y-direction positioning wheels 34 mounted below the longitudinal beams 24 of the U-shaped base 20. In the example shown in Figure 3 , there are provided 4 Z-direction support wheels 36 arranged at intervals and 3 Y-direction positioning wheels 34 arranged at intervals. The Z-direction support wheels 36 are connected to the underside of the longitudinal beams 24 by associated connecting members. The Z-direction support wheels 36 are configured to be able to roll on the upper surfaces of the guide rails 42, in particular on the upper surfaces of the guide rail body sections 422. The rolling of the Z-direction support wheels 36 on the upper surfaces of the guide rail body sections can on the one hand enable smooth movement of the optical detection frame device 1 to the detection position, and on the other hand provide sufficient vertical support to the U-shaped base 20 and the detection frame 10. As shown in Figure 6 , the Z-direction support wheels 36 can include only one roller 362 arranged on either side of the roller connecting member 361. In an example not shown, the Z-direction support wheels 36 can include two rollers arranged on both sides of the wheel connecting member. The Y-direction positioning wheels 34 are connected to the underside of the longitudinal beams 24 by their guide wheel connecting members 341. As shown in Figure 7 , the Y-direction positioning wheels 34 include a pair of guide wheels 342 that are able to roll on the opposite side surfaces of the guide rails 42. This arrangement of the pair of guide wheels can provide guiding and limiting functions to limit the movement of the optical detection frame device 1 along the guide rails 42, and can also prevent the optical detection frame device 1 from swaying in the Y-direction. The combined use of the Y-direction positioning wheels 34 and the Z-direction support wheels 36 can ensure that the optical detection frame device 1 moves stably and smoothly along the guide rails 42 to the detection position.

[0059] With reference toFigure 1 and Figures 8-10 The optical detection frame device 1 can be limited at the detection position by a stop limiting assembly 50. The stop limiting assembly 50 can be disposed near the distal end of the guide rail main body segment 422 distal to the guide rail introduction segment 421 for defining a stop position of the optical detection frame device 1 on the guide rail 42. As shown in Figures 8-10 , the stop limiting assembly 50 includes a stop portion 54 and an inverted T-shaped support 52. The inverted T-shaped support 52 includes a base portion 521 and an upright portion 522 perpendicular to each other. The base portion 521 and the upright portion 522 can be integrally formed. The base portion 521 can be fixed to the ground by fasteners and fixing plates so as to remain stationary. The side of the upright portion 522 facing the guide rail main body segment 422 is provided with the stop portion 54. The stop portion 54 is configured to abut against the front end face of the front end portion of the longitudinal beam 24 of the U-shaped base 20 so as to prevent the optical detection frame device 1 from continuing to move forward, thereby playing a limiting role. The stop portion 54 can be made of a material with a certain elasticity. The front end face of the front end portion of the longitudinal beam 24 can be provided with an elastic abutting piece 29 (see Figure 3 ). Such elastic abutment can buffer the impact force of the front end face of the front end portion of the longitudinal beam 24 abutting against the stop portion 54, thereby ensuring smooth abutment.

[0060] Referring to Figure 1 and Figures 8-10 , the optical detection frame device can be locked at the detection position by a locking assembly 60. The locking assembly 60 is disposed outside and adjacent to the stop limiting assembly 60 for locking the optical detection frame device 1 in place on the guide rail 42. As shown in Figures 8-10 , the locking assembly 60 can include a stationary base 62, a first locking component 64 disposed on the upper surface of the base, and a second locking component 66 disposed on the upper surface of the U-shaped base 20. Specifically, the second locking component 66 can be disposed on the upper surface of the transverse piece 26. The first locking component 64 and the second locking component 66 cooperate to lock the optical detection frame device 1 in place. In Figures 8-10In the illustrated example, the first locking component 64 is in the form of a collar, and the second locking component 66 is in the form of a hook. They cooperate with each other to prevent the optical detection frame device 1 from retreating (i.e. moving in a direction opposite to the X direction). The locking assembly 60 can further include an actuator 65 disposed on the upper surface of the base to actuate the first locking component 64. In other unillustrated examples, the first locking component 64 and the second locking component 66 can be other components that cooperate with each other to function as a locking. The base 62 is also in the form of an inverted T shape, including a base portion 621 and a vertical portion 622 perpendicular to each other. The base portion 621 and the vertical portion 622 can be integrally formed. The base portion 621 can be fixed to the ground by fasteners and fixing plates, so as to remain stationary. A positioning member 68 is disposed at the middle upper portion of the vertical portion 622. The positioning member 68 can extend through the vertical portion 622. The extension amount of the positioning member 68 extending through the vertical portion 622 is adjustable, so as to further adjust the detection position of the optical detection frame device. The end of the positioning member 68 can be sleeved with an elastic sleeve 681. The front side of the transverse member 26 can be provided with an abutting block 27 that cooperates with the positioning member 68. The abutting block 27 can be elastic. For example, the positioning member 68 abuts against the abutting block 27 on the U-shaped base 20 through the elastic sleeve 681 to determine the distance of the U-shaped base 20 relative to the vertical portion 622 of the locking assembly 60, so as to fine-tune the optical detection frame device 1 at the detection position.

[0061] The following will be described in combination with Figures 11-12To elaborate the operation of the optical detection frame device 1 according to the present disclosure. Before the optical detection frame device 1 is moved to the detection table 3, the four avoiding beams 14 are kept coupled to the main body of the detection frame 10 by quick-release connectors to ensure the lateral stability of the detection frame 10. With the piece to be detected (e.g. a vehicle) 2 already positioned on the detection table 3, the optical detection frame device 1 can be moved towards the guide rail assembly 40. When the optical detection frame device 1 approaches the guide rail assembly 40, the avoiding beams 14 can be quickly released to provide a passable space to allow the optical detection frame device 1 to move to its detection frame 10 wrapping around the detection table 3 and the piece to be detected 2 thereon. As the front walking wheels 32 approach the upwardly inclined rail introduction section 421 of the guide rail 42 and move outside the rail introduction section 421, the guide wheels 342 of the Y-direction positioning wheels 34 start to abut and roll along the opposite side surfaces of the guide rail 42 to guide the optical detection frame device 1 to move along the guide rail 42 and prevent the optical detection frame device 1 from swinging in the Y-direction. The front walking wheels 32 continue to travel until the rollers 362 of the Z-direction support wheels abut and roll along the upper surface of the rail introduction section 422, at which time the front walking wheels 32 have been lifted off the ground, the optical detection frame device 1 is caused to continue to move forward by the rollers 362 of the Z-direction support wheels rolling on the upper surface of the rail introduction section 422. When the optical detection frame device 1 travels to the point where the elastic abutment 29 of the front end portion of the longitudinal beam 24 abuts the stop portion 54 of the stop limiting assembly 50, the optical detection frame device 1 stops moving. At this time, the operator can use the first and second locking components 64 and 66 of the locking assembly 60 in cooperation to lock the optical detection frame device 1 in place. In addition, the operator can manually adjust the extension amount of the adjustment member 68 to adjust the position of the U-shaped base 20 relative to the vertical portion 622 of the locking assembly 60, so as to fine-tune the detection position of the optical detection frame device 1. In this way, the optical detection frame device 1 has been positioned at the detection position, ready to assist in optical measurement by providing a preset coded reference point. After the optical detection frame device 1 is positioned at the detection position, at least a portion of the avoiding beams 14 can be re-coupled to provide lateral stability (refer to Figure 12 ).
