Description

Technical Field

[0001] The present application belongs to the technical field of scanning equipment, and specifically relates to a foldable large-format high-definition scanner. Background Art

[0002] Large-format non-contact high-definition scanners are high-precision instruments, most of which are complex in structure, large in size, heavy in weight, and inconvenient to carry. They are not conducive to remote deployment and installation and use, and it is difficult to meet users' needs for fast and efficient response speed and service standards. In addition, when it comes to data collection of high-value cultural relics that cannot be transported or have restrictions on leaving the site, such as high-value cultural relics, the equipment needs to be on-site for high-definition scanning data collection. Since the transportation, installation, and commissioning of the equipment require the presence of professional personnel, the overall transportation cost, time cycle, and labor cost are increased, thereby making the project cycle and cost high. Utility Model Content

[0003] The purpose of the embodiments of the present application is to provide a foldable large-format high-definition scanner which is compact in structure after folding and easy to install and use.

[0004] To achieve the above objectives, the present application provides a foldable large-format high-definition scanner, comprising:

[0005] A frame having a crossbeam;

[0006] A column, wherein the column is slidably connected to the crossbeam via a first slide;

[0007] A light source, wherein the light source extends horizontally and is perpendicular to the crossbeam in a scanning working state, and one end of the light source is rotatably connected or detachably connected to the first slide table;

[0008] A cantilever, one end of which is connected to the column via a second slide, and the cantilever is configured to slide along the column and be able to flip upward to a position parallel to the column; wherein a camera and a lens are provided at one end of the cantilever away from the column;

[0009] A scanning platform for placing scanned objects, the scanning platform being supported by a support frame; the support frame being connected to the frame and being foldable and unfoldable;

[0010] Among them, the light source is configured to be able to rotate upward and fit tightly against the column, or to be folded by disassembling; the column can be rotated and laid flat so as to be parallel to the crossbeam, and the support frame is configured to be able to drive the scanning platform to flip to a vertical direction and move closer to the frame when folded, so that the large-format high-definition scanner is in a folded state.

[0011] In one embodiment of the foldable large-format high-definition scanner described in the utility model, the light source can be in various forms as long as it can provide sufficient lighting effect for the scanner. In one scheme, the light source is preferably a strip light source so that the light source can provide long and localized lighting on the large-format scanning platform. The connection mode of one end of the light source to the first slide can be a rotating connection or a detachable connection. In the scheme of rotating connection, the light source can be turned up and close to the column, so as to achieve the effect of folding. For the specific rotation mode, the pivoting or ball joint rotation mode can be adopted. Pivoting means that the light source rotates around the long axis set on the first slide to achieve upward flipping, so as to be close to the column. If the ball joint mode is adopted, a joint socket (with an upward notch for accommodating thickness) can be set on the first slide, and then the joint head can be embedded in the joint socket, and the light source can be turned up by rotating the joint, so that the light source is folded and close to the column. In the scheme of folding by disassembling the light source, after the light source is disassembled, the column can be close to achieve the purpose of folding, or the light source can be placed at other positions of the scanner, or separated from the scanner and placed separately. Those skilled in the art can implement the above connection scheme according to the instructions of the present invention and existing mechanical design and manufacturing knowledge.

[0050] Please also read Figure 1 , Figure 8 , Fig.15, the foldable large-format high-definition scanner provided in an embodiment of the present application is now described. The foldable large-format high-definition scanner includes a frame 10, a longitudinal arm 20, a strip light source 30 and a scanning platform 40. The frame 10 has a crossbeam 11, and the crossbeam 11 is arranged horizontally. An operating table 14 is provided at one end of the frame 10, and scanning working parameters can be set and adjusted by operating the operating table 14. The longitudinal arm 20 is slidably connected to the crossbeam 11 through a first slide 12, and a camera and a lens are installed on the longitudinal arm 20, and the camera and the lens form a scanning module 23. The longitudinal arm 20 can be rotated and laid flat so as to be parallel to the crossbeam 11, that is, the longitudinal arm 20 can be folded to be parallel to the crossbeam 11.

[0051] The bar light source 30 extends in the horizontal direction when in the scanning working state, and the bar light source 30 and the crossbeam 11 are in a mutually perpendicular state. One end of the bar light source 30 is pivotally connected to the first slide 12, and the bar light source 30 can rotate upward and be close to the longitudinal arm 20. The scanning platform 40 is used to support and place the scanned object. The scanning platform 40 is supported by a support frame 50 at the bottom, and the support frame 50 is connected to the frame 10. The support frame 50 can be folded and unfolded. When the support frame 50 is folded, it can drive the scanning platform 40 to flip to the vertical direction and move closer to the frame 10, so that the large-format high-definition scanner can be turned into a folded state. After the various components are folded into place, the width and height of the scanner are greatly reduced, the structure of the whole machine is compact, the size of the whole machine is reduced, and it is convenient to pack and transport, and it is easy to load. When the scanner needs to be used, the whole machine can be unfolded and returned to its position by operating in the opposite direction of folding. The parts are always together, and the purpose of quick installation of the whole machine is achieved.

[0052] The bottom of the rack 10 and the support frame 50 are both equipped with horizontal adjustment support casters 16, which can be used to adjust the level of the whole machine. At the same time, the pulley function of the horizontal adjustment support casters 16 can be used to slide and transport the whole machine according to actual needs, without the need for a large amount of manpower and equipment, and can be flexibly moved, greatly reducing the difficulty of transporting the equipment. A fixed foot cup 17 can be provided at the bottom of the rack 10 to support the equipment more stably.

[0053] The computer and control module are installed inside the rack 10, and the cables are built into the rack 10. All electrical appliances are integrated into one, making the overall equipment clean and tidy. The wiring is completely built-in, and the lines are not affected when the whole machine is folded and unfolded. There is no need to rewire the wiring. After the whole machine is installed, you only need to repower it to start debugging and working.

[0054] Compared with the prior art, the foldable large-format high-definition scanner provided by the present application has a strip light source 30 that can be folded to be close to the longitudinal arm 20, and the longitudinal arm 20 is rotated and folded to be parallel to the crossbeam 11, and then the longitudinal arm 20 and the strip light source 30 are folded and parallel to the crossbeam 11, and the length of the scanner in the height direction is greatly reduced; when the support frame 50 at the bottom of the scanner is folded, it can drive the scanning platform 40 to flip to a vertical direction and move closer to the frame 10, and the scanner becomes a folded state, which greatly reduces the overall width and height of the scanner, and the size of the whole machine is greatly reduced, which can be easily carried, convenient for transportation and installation of the whole machine, and conducive to remote deployment. It can be quickly disassembled and assembled, quickly deployed and used, and can meet the user's requirements for fast and efficient response speed and service standards.

[0055] See also Figures 1 to 3 The longitudinal arm 20 includes a column 21 and a cantilever 22. One end of the column 21 is slidably connected to the crossbeam 11 through the first slide 12, and the column 21 can slide back and forth horizontally relative to the crossbeam 11. The column 21 can rotate and lay flat to be parallel to the crossbeam 11. One end of the cantilever 22 is slidably connected to the column 21 through the second slide 24, and the height position of the cantilever 22 on the column 21 is adjustable. The cantilever 22 can rotate upward to a position parallel to the column 21. The camera and the lens are mounted on the other end of the cantilever 22. The other end of the cantilever 22 is provided with a third slide that can slide up and down, and the camera is fixed on the third slide. By operating the operating table 14, the height position of the cantilever 22 and the height position of the camera on the cantilever 22 can be adjusted, so that the object distance and the image distance can be adjusted, and the focusing operation of different resolutions can be completed.

[0056] The first slide 12 includes a slider and a shell. The slider and the crossbeam 11 are slidably matched. The shell is connected to the top of the slider through a vertically arranged shaft and can rotate horizontally relative to the slider through the shaft. The bottom end of the column 21 is pivoted in the shell. The fixing screws pass through the shell and the column 21. When the fixing screws are not removed, the column 21 cannot rotate relative to the shell. When the column 21 needs to be laid down, the fixing screws on the side are first removed, and then the column 21 can be laid down; one end of the strip light source 30 is pivoted to the shell through a connecting rod. When the scanner is working, one end of the strip light source 30 is against the shell and is in a horizontal state. When the strip light source 30 needs to be folded, the strip light source 30 is flipped upwards. The front and rear ends and the top of the shell are open, so that the column 21 can be laid down to a horizontal state, and the strip light source 30 can be flipped to be parallel to the column 21. Figure 2 As shown, the cantilever 22 is rotated upward to be parallel to the column 21; Figure 3 As shown, the height screws of the shell side wall have been removed, and the column 21 is laid down to the rear side; Figure 4 As shown, the column 21 has been laid down to a horizontal state; Figure 5 As shown, the bar light source 30 can be turned upward around the housing; Figure 6As shown, the strip light source 30 has been turned 180 degrees and is parallel to the cantilever 22; Figure 7 As shown, one end of the column 21 rotates horizontally through the first slide 12; Figure 8 As shown, the entire longitudinal arm 20 and the strip light source 30 have been horizontally rotated to just above the crossbeam 11 , and the upright post 21 is parallel to the crossbeam 11 .

[0057] When the scanning platform 40 is rotated to a vertical direction, it can abut against the side of the beam 11, so that the width of the whole machine is smaller and the structure of the whole machine is more compact.

[0058] See also Fig. 9 , Fig.10 , a connecting plate 13 is provided at the end of the column 21, and the column 21 is detachably fixed to the crossbeam 11 through the connecting plate 13 after being rotated and folded. Two connecting plates 13 are provided at one end of the column 21 away from the first slide 12, and the two connecting plates 13 are symmetrically arranged on both sides of the end of the column 21. After the strip light source 30 and the column 21 are folded and rotated into place, screws are used to pass through the connecting plates 13 and connect to the crossbeam 11, so that the free end of the column 21 is fixed relative to the crossbeam 11, and the two connecting plates 13 play the role of supporting and fixing the column 21. When the column 21 needs to be unfolded, the screws are loosened and the connecting plates 13 are removed.

[0059] See also Fig.11 and Fig.12 The support frame 50 includes a lifting rod 51 and a bracket 52 that can be unfolded and folded. The length of the lifting rod 51 is adjustable, so that the height of the scanning platform 40 can be adjusted. When the bracket 52 is folded, it drives the scanning platform 40 to move to a vertical direction, that is, after the bracket 52 is folded, it can drive the scanning platform 40 to flip and move to a vertical direction, so that the scanning platform 40 can be folded and retracted.

[0060] See also Figure 8 , Fig.11 The bracket 52 can be extended and retracted in the horizontal direction so that the horizontal position of the scanning platform 40 can be adjusted. By adjusting the bracket 52, one side of the scanning platform 40 can be extended into the space below the crossbeam 11 of the frame 10, that is, the workpiece to be scanned placed on the scanning platform 40 can also partially pass through the frame 10, and the scanned workpiece can be scanned and spliced ​​multiple times in the width direction of the scanning platform 40, which can break through the limitation of double width scanning and increase the maximum scannable size.

[0061] The frame 10 is provided with a bottom beam 15 below the cross beam 11, and a portion of the scanning platform 40 can pass through the space between the cross beam 11 and the bottom beam 15 when the bracket 52 is unfolded, so that the scanned piece can be scanned in sections within the span size of the frame 10. In other words, the scanned piece placed on the scanning platform 40 can also partially pass through the frame 10, and the scanned piece can be scanned and spliced ​​multiple times in the width direction of the scanning platform 40, which can break through the limitation of the existing large-format scanner that can only scan twice the width, and expand the scannable size in the equipment of the same size.

[0062] See also Fig.13 and Fig.14 , two brackets 52 are provided at the bottom of the scanning platform 40, and the two brackets 52 are arranged in parallel and spaced apart. The bracket 52 includes a base 520, a first connecting rod 530 and a second connecting rod 540. The base 520 is fixed to the frame 10, and a horizontal adjustment support caster 16 is provided at the bottom of the bottom of the base 520 away from the frame 10, and the longitudinal section of the base 520 is U-shaped. Figures 15 to 17 As shown, the first connecting rod 530 includes two first plates 531 arranged in parallel and spaced apart, the second connecting rod 540 includes two second plates 541 arranged in parallel and spaced apart, and a plurality of fixing plates 560 are connected between the two brackets 52, wherein two ends of the two fixing plates 560 are respectively fixed to the upper side of the second plates 541, and two ends of another fixing plate 560 are respectively fixed to the lower side of the second plates 541. One end of the first connecting rod 530 is fixed to the bottom end of the lifting rod 51, and the other end of the first connecting rod 530 is slidably connected to one end of the second connecting rod 540, and the other end of the second connecting rod 540 is hinged to the base 520. Specifically, the two first plates 531 are arranged on opposite sides of the lifting rod 51 and are connected and fixed to the lifting rod 51. The second plate 541 is provided with a slide groove 543. The end of the first plate 531 away from the lifting rod 51 is provided with a first rotating shaft 532. The first rotating shaft 532 slides in cooperation with the slide groove 543, thereby realizing a sliding connection between the first connecting rod 530 and the second connecting rod 540. The end of the second plate 541 away from the first plate 531 is pivotally connected to the base 520 through the second rotating shaft 542.

[0063] like Fig.13 , Fig.14 As shown, when one end of the first link 530 slides to the end of the second link 540, it can rotate upward around the second link 540 by a first angle. Figures 15 to 17 As shown, the second connecting rod 540 can rotate upwardly around the base 520 by a second angle. Figures 11 to 14As shown, the bracket 52 is provided with an automatic locking pin 550. When the automatic locking pin 550 at the bottom of the bracket 52 is opened, the scanning platform 40 is in a horizontally movable state. After the scanning platform 40 is pulled outward to the limit position, the automatic locking pin 550 automatically locks the first connecting rod 530 and the second connecting rod 540 of the bracket 52. Then, the scanning platform 40 is lowered to the lowest position through the lifting rod 51. At this time, the first rotating shaft 532 slides to the end of the sliding groove 543, and an upward force is applied to the scanning platform 40 so that the first connecting rod 530 rotates upward by a first angle around the first rotating shaft 532, that is, the scanning platform 40 also rotates by the first angle. Figures 15 to 17 As shown, upward force is applied again, the second connecting rod 540 rotates upward by a second angle through the second rotating shaft 542, and the scanning platform 40 also rotates by the second angle. At this time, the scanning platform 40 rotates a total of 90 degrees and is exactly in an upright state.

[0064] After the first connecting rod 530 rotates upward by a first angle and the second connecting rod 540 rotates upward by a second angle, the scanning platform 40 just rotates to a vertical direction. The sum of the first angle and the second angle is equal to 90 degrees, so that after the bracket 52 is folded upward twice, the scanning platform 40 just flips upward to a vertical direction. In this embodiment, the first angle is set to 30 degrees and the second angle is set to 60 degrees. It can be understood that the first angle and the second angle can also be set to other angles.

[0065] Since an automatic locking pin 550 is disposed between the first link 530 and the second link 540, when the first link 530 rotates upward by a first angle, the first link 530 and the second link 540 are locked and fixed by the automatic locking pin 550. After the automatic locking pin 550 is locked, the first link 530 cannot rotate relative to the second link 540, thereby preventing the scanning platform 40 from turning downward. Fig.16 , Fig.18 and Fig.19 , a mounting groove is provided at the position where the lifting rod 51 is installed on the back of the scanning platform 40, and both ends of the mounting groove are closed. The groove wall at one end of the mounting groove of the scanning platform 40 and the corresponding position of the base 520 are respectively provided with threaded holes 41. When the second connecting rod 540 rotates upward by a second angle, a fixing screw (not shown) is used to pass through the threaded holes 41 of the scanning platform 40 and the base 520, so that the scanning platform 40 and the base 520 can be relatively fixed, and the scanning platform 40 can be prevented from turning downward. The scanning platform 40 is adjusted to the lowest height by the lifting rod 51 before the bracket 52 is folded, so as to avoid the bracket 52 from being unable to fold due to the impact between the scanning platform 40 and the crossbeam 11 of the frame 10, that is, before the bracket 52 is folded, the scanning platform 40 is adjusted and lowered to the lowest position, so as to avoid the phenomenon that the scanning platform 40 cannot be folded due to the interference between the crossbeam 11 during the folding operation of the bracket 52.

[0066] The following describes the folding process of the scanner:

[0067] (1) See Figure 1 , move the longitudinal arm 20 to a position close to the end of the cross beam 11; Figure 2 , rotate the cantilever 22 upward to a position parallel to the column 21, and complete the folding of the cantilever 22;

[0069] (3) See Figure 7 , Figure 8 , the column 21 is rotated horizontally by 90 degrees, so that the column 21 and the strip light source 30 are moved above the beam 11 and parallel to the beam 11; Fig. 9 , Fig.10 , the crossbeam 11 is connected and fixed to the column 21 by screws and the connecting plate 13, and the folding of the longitudinal arm 20 and the strip light source 30 is completed;

[0070] (4) See Fig.11 , open the automatic locking pin 550 at the bottom of the bracket 52, and pull the scanning platform 40 out horizontally. After being pulled out to the right position, the automatic locking pin 550 automatically locks the first connecting rod 530 and the second connecting rod 540 of the bracket 52, so that the first connecting rod 530 will not slide relative to the second connecting rod 540 during the upward flipping of the scanning platform 40;

[0071] (5) See Fig.12 , adjust the scanning platform 40 down to the lowest height;

[0072] (6) See Fig.13 , Fig.14 , the scanning platform 40 is turned upward by 30 degrees around the first rotation axis, and the automatic locking pin 550 locks the position;

[0073] (7) See Fig.15 , Fig.16 , the scanning platform 40 is turned upward 60 degrees around the second rotation axis, and the scanning platform 40 is in a vertical state at this time; Fig.18 , Fig.19 , fixing screws are passed through the screw holes of the scanning platform 40 and the base 520 to fix the scanning platform 40 and the base 520 relatively to prevent the scanning platform 40 from flipping downward, that is, the scanning platform 40 is in a locked state, and the folding is completed.

[0074] When the whole machine is folded, only a few simple reinforcements are needed to fix the foldable parts. The circuits and components of the whole machine do not need to be disassembled, which reduces the difficulty of assembly after it is in place and can achieve long-distance delivery.

[0075] When the scanner needs to be used, only a few simple actions are required to complete the unfolding and returning of the whole machine in the opposite direction of folding. The parts are always together, and there is no need to temporarily find the parts for assembly, which can meet the needs of quick installation of the whole machine; because the wiring is completely built into the frame 10, the lines of the whole machine are not affected when it is folded and unfolded, so there is no need to rewire and wire. After the whole machine is installed, it only needs to be powered on again to start debugging and working. The foldable large-format high-definition scanner provided in the embodiment of the present application is simple to fold and unfold, the whole machine has a compact structure after folding, the size of the whole machine is greatly reduced, and it is convenient to pack and transport, easy to load, and can be remotely deployed; after the whole machine is unfolded, it can be debugged and worked after being powered on again, which can meet the response speed and fast and efficient service standards required by users. For data collection that cannot be transported or has departure restrictions, such as data collection of high-value cultural relics, remote delivery, rapid disassembly and assembly, rapid deployment and rapid use can be achieved, thereby saving transportation costs, time cycles and labor costs, and reducing project cycles and costs.

[0076] In one embodiment, the scanning platform 40 includes at least two foldable panels 42. After the scanning platform 40 is rotated to the vertical direction, the scanning platform 40 itself is folded, or the scanning platform 40 itself is folded first, and then the scanning platform 40 is rotated to the vertical direction by folding the support frame 50, so as to further reduce the height of the whole machine, and the overall size becomes smaller after the whole machine is folded. Fig. 20 The scanning platform 40 includes two foldable plates 42, and a hinge is installed between the two plates 42. The hinge allows one plate 42 to be flipped upward to achieve folding the two plates 42 together. During operation, one plate 42 is first flipped upward and folded, and then the scanning platform 40 is flipped by folding the bracket 52.

Any modification, equivalent substitution and improvement made within the spirit and principle of the present application shall be deemed to fall within the protection scope of the present application.
