[0002] In recent years, with the progress of technology, the number of factory automation devices has been increasing day by day. In the industrial production process, scanners play an important role in multiple links such as industrial product design, product quality inspection and control, and reverse engineering. Existing industrial scanners can only control the scanning component to move and scan in one direction, resulting in problems such as low scanning accuracy and efficiency, and great limitations on the scanned object.

[0003] Publication (Announcement) Number: CN205071124U, Publication (Announcement) Date: Mar. 2, 2016. It relates to an intelligent industrial scanner, including a load platform for placing an object to be scanned, a column arranged on the load platform, and a camera assembly. The industrial scanner further includes a height adjustment system. The height adjustment system includes a guide rail and a lifting motor installed on the guide rail. The guide rail is installed on the column, and the camera assembly is installed on the guide rail and moves up and down along the guide rail driven by the lifting motor. And the height adjustment system further includes a PLC module for receiving and sending execution signals of the height adjustment system. The lifting motor is electrically connected to the PLC module. This comparative document discloses an intelligent industrial scanner that can lift and adjust the distance between the camera and the object to be measured. However, this scanner still has problems such as a small working range of the scanner, inability to scan large-plane components, low scanning efficiency, and poor accuracy. Therefore, the utility model proposes an industrial scanner for non-contact full-plane scanning to solve the above problems and improve the scanning accuracy of the scanner. Summary of the Invention

[0004] The utility model provides an industrial scanner for non-contact full-plane scanning to solve the above problems in the prior art.

[0005] To achieve the above object, the solution provided by the present utility model is: a non-contact full-plane scanning industrial scanner, including a scanning and sampling component, a frame-type moving component, and a planar scanning table. The scanning and sampling component includes a grating, a mirror, and a photoelectric signal detector. The frame-type moving component includes a first moving rod and a second moving rod. The planar scanning table is a sliding type loading table, and the sliding type loading table includes a loading platform, a loading platform base, and a plurality of sliding tracks and fixing blocks installed on the loading platform base. The scanning and sampling component is installed on the frame-type moving component and moves in the front, rear, left, and right four directions on the horizontal plane above the planar scanning table, and the threshold of the moving range is set 3 to 5 cm outside the edge of the planar scanning table. In this scanner, the first moving rod and the second moving rod are perpendicular to each other, and the moving range of the scanning and sampling component is larger than that of the planar scanning table, so that the full-plane scanning of the scanning table can be achieved, and the effect of scanning large-plane workpieces can be achieved.

[0006] Preferably, the industrial scanner further includes a rigid frame. The rigid frame is provided with a plurality of sliding rails. The two ends of the first moving rod and the second moving rod are respectively installed with pulleys and embedded in the sliding rails of the rigid frame. The rigid frame constructs the basic structure of the scanner and is used to support the structural stability of the industrial scanner. The moving rods of the frame-type moving component are in the sliding rails at the top of the rigid frame, which facilitates the moving component to move arbitrarily in the horizontal plane and reach any position.

[0007] Preferably, the first moving rod is provided with a side guiding groove. The scanning and sampling component is installed with a pulley and embedded in the side guiding groove of the first moving rod. Using the pulley facilitates the horizontal movement of the scanning and sampling component along the first moving rod.

[0008] Preferably, the industrial scanner is further provided with a hinge guiding groove. A moving hinge is embedded in the guiding groove of the hinge guiding groove. One end of the moving hinge is fixed to the scanning and sampling component, and the other end is embedded in the hinge guiding groove. The hinge guiding groove is used to limit the stretching direction of the moving hinge, thereby controlling the movement of the scanning and sampling component in the direction of the first moving rod.

[0009] Preferably, the second moving rod is provided with a lower guiding groove. The first moving rod is embedded in the lower guiding groove of the second moving rod. The lower guiding groove of the second moving rod is used to control the displacement of the first moving rod, that is, to realize the arbitrary displacement of the scanning and sampling component in any direction in a horizontal plane, so that the sampling range of the scanning and sampling component can cover the entire planar scanning table and the scanning is more comprehensive.

[0010] Preferably, the scanning and sampling assembly further includes an LED light source and a lens. The LED light source is installed at the inner top of the scanning and sampling assembly to provide the required light source for sampling. The lens is installed between the LED light source and the grating to focus the light of the light source into a spot. The grating is provided at the focal point of the lens to disperse the light focused by the lens into multiple beams of specific light. The scanning and sampling assembly is provided with a heat dissipation window on the side plate of the mirror. Since the mirror generates heat when reflecting light, if not dissipated for a long time, it is likely to cause a failure of the optoelectronic signal sensor of the scanner, resulting in the inability of the scanner to work. Therefore, a window-type heat dissipation opening is provided on the side plate of the mirror, achieving the effect of dust prevention and heat dissipation.

[0011] Preferably, the scanning and sampling assembly is further provided with a plurality of fans, which are fixed equidistantly outside the heat dissipation window of the side plate of the mirror to cool and dissipate heat from the mirror.

[0012] Preferably, the industrial scanner is further provided with a monitor bracket. The monitor bracket is provided with a connecting rod, and a rotating shaft is fixed between the connecting rods. The monitor bracket can rotate according to the direction of the rotating shaft to control the orientation of the monitor bracket.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Specific embodiments of the present utility model will be described in detail below. It should be noted that the embodiments described here are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the following embodiments, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present utility model.

[0019] First Embodiment:

[0020] The first embodiment of the present utility model provides an industrial scanner for non-contact full-plane scanning, the structure of which is as shown in Figure 1 、 Figure 2 and Figure 3 , which includes a scanning and sampling component 10, a frame-type moving component 20, and a planar scanning table 30. The scanning and sampling component 10 includes a grating, a reflector, and a photoelectric signal detector. The frame-type moving component 20 includes a first moving rod 21 and a second moving rod 22. The planar scanning table 30 is a sliding loading table, and the sliding loading table includes a loading platform, a loading platform base, and a plurality of sliding tracks and fixing blocks installed on the loading platform base. The scanning and sampling component 10 is installed on the frame-type moving component 20 and moves in the front, rear, left, and right directions on the horizontal plane above the planar scanning table 30, and the threshold of the moving range is set 3 to 5 cm outside the edge of the planar scanning table 30.

[0021] On the industrial scanner of this embodiment, there is a loading table mounting frame located in the middle plane. The loading platform base of the planar scanning table 30 is installed above the frame. Columnar sliding guide rails are installed on the loading table base to facilitate the installation and disassembly of the loading table. In this embodiment, when the industrial scanner is working, fixing parts are installed at both ends of each sliding guide rail to fix the position of the loading platform on the loading table base, avoiding errors such as scanning afterimages and overlaps caused by the movement of the loading platform during the scanning process.

[0022] In this embodiment, the industrial scanner further includes a rigid frame 40. The rigid frame 40 is connected in a cube shape, and an outer shell is installed on its outside, thus playing a role in supporting the structure of the industrial scanner and dustproofing inside the scanner. The rigid frame 40 is provided with a number of sliding rails, and the sliding rails are groove-shaped tracks arranged on the support beams of the rigid frame 40. The two ends of the first moving rod 21 and the second moving rod 22 are respectively installed with pulleys and embedded in the sliding rails at the top of the rigid frame 40. The tracks facilitate the sliding of the pulleys between the frames, and thus facilitate the movement of the first moving rod 21 and the second moving rod 22.

[0023] In this embodiment, the first moving rod 21 is provided with side guide grooves. The side guide grooves are of a double-groove structure and are located on both side surfaces of the first moving rod 21. The scanning and sampling assembly 10 is equipped with pulleys and is embedded in the side guide grooves of the first moving rod 21. The scanning and sampling assembly 10 is provided with a main frame in a convex shape. Two rows of symmetric pulleys placed inside the frame are installed at the top of the frame, and the pulleys are embedded in the side guide grooves of the first moving rod 21. The scanning and sampling assembly 10 can move in the front and back directions.

[0024] In this embodiment, the industrial scanner is further provided with a hinge guide rail. A moving hinge 24 is embedded in the guide groove of the hinge guide rail. The moving hinge 24 is fixed to the scanning and sampling assembly 10. The hinge guide rail is fixed to the second moving rod 22. One end of the hinge is fixed to the scanning and sampling assembly 10, and the other end passes through the hinge guide rail and is connected to the motor. By pulling the hinge to tighten with the motor, the scanning and sampling assembly 10 is driven to slide forward. When the scanning and sampling assembly 10 slides backward, the hinge loosens.

[0025] In this embodiment, a lower guide groove is provided on the second moving rod 22 of the scanner. The lower guide groove is a single groove. A pulley for connecting the second moving rod 22 is fixed on the first moving rod 21, and the pulley is embedded in the lower guide groove of the second moving rod 22, so as to control the displacement of the scanning assembly in the left and right directions.

[0026] On the industrial scanner of this embodiment, the first moving rod 21 and the second moving rod 22 are not fixed. The first moving rod 21 is located below the second moving rod 22. When the scanning and sampling assembly 10 needs to move horizontally, by means of the pulley of the first moving rod 21 sliding in the guide groove of the second moving rod 22, the first moving rod 21 and the scanning and sampling assembly 10 are driven to move simultaneously.

[0027] In this embodiment, the scanning and sampling assembly 10 further includes an LED light source and a lens. The LED light source is installed at the inner top of the scanning and sampling assembly 10. The lens is installed between the LED light source and the grating. The grating is provided at the focal point of the lens. The scanning and sampling assembly 10 is provided with a heat dissipation window for the mirror side plate. The scanning and sampling assembly 10 is composed of a scanning assembly housing, an LED light source, a lens, a mirror, and a photoelectric signal detector, and is controlled by a console for sampling. When a sampling signal is received, the LED light source generates a high-brightness light beam, and the grating divides it into multiple light sources with a specific structure. The light beam is focused by the lens into a light spot at the focal point of the lens. When the light spot irradiates the workpiece to be measured, the light spots in different regions will have differences in color, texture, and reflection degree. These reflected signals are captured by the scanner again, and after being reflected by the mirror, they are guided to the photoelectric sensor. The photoelectric sensor receives the reflected light signal and converts it into an electrical signal, which is processed by the controller and read to generate an image of the scanned workpiece, and the workpiece image is displayed on the display.

[0028] In this embodiment, the scanning and sampling assembly 10 is further provided with a number of fans, which are fixedly arranged at equal intervals outside the heat dissipation window of the side plate of the reflector. Since the light source is concentrated into a light spot during the operation of the scanner, the heat generated by the light during the operation of the reflector is likely to damage the scanning and sampling assembly 10. Therefore, by setting a fan in the heat dissipation hole for auxiliary heat dissipation, the heat accumulation of the scanning and sampling assembly 10 can be avoided from damaging the industrial scanner.

[0029] In this embodiment, the industrial scanner is further provided with a display bracket 41. The display bracket 41 is provided with a connecting rod, and a rotating shaft is fixed between the connecting rods. The display bracket 41 is installed with a moving slider, and the moving slider is fixed in the slide rail of the rigid frame 40. The display bracket 41 is structurally fixed by the connecting rod, and a number of rotating shafts provided between the connecting rods enable the display bracket 41 to swing left and right, and the moving slider controls the vertical displacement of the display bracket 41, facilitating the user to view the scanning result.

[0030] In this embodiment, by setting a moving rod that can displace in the front-back direction and left-right direction in the horizontal plane, the industrial scanner is no longer limited to scanning in only one direction, increasing the scanning range of the scanner, achieving the effect of being able to scan large-plane industrial components, improving the scanning efficiency, and increasing the scanning accuracy.

[0031] Second Embodiment:

[0032] The second embodiment of the present utility model also proposes an industrial scanner for non-contact full-plane scanning, the structure of which is as Figure 3 shown. This full-plane scanning industrial scanner includes a scanning and sampling assembly 10, a frame-type moving assembly 20, and a plane scanning table 30. The scanning and sampling assembly 10 includes a grating, a reflector, and a photoelectric signal detector. The frame-type moving assembly 20 includes a first moving rod 21 and a second moving rod 22. The plane scanning table 30 is a sliding type loading table, and the sliding type loading table includes a loading platform, a loading platform base, and a number of sliding rails and fixing blocks installed on the loading platform base. The slide rail and the second moving rod 22 are in the same direction. The scanning and sampling assembly 10 is installed on the frame-type moving assembly 20 and moves in the front, rear, left, and right four directions on the horizontal plane above the plane scanning table 30, and the threshold of the moving range is set 3 to 5 cm outside the edge of the plane scanning table 30.

[0033] In this embodiment, the industrial scanner further includes a rigid frame 40, and the rigid frame 40 is connected in a cube shape, and its outside is installed with a housing, thus playing a role in supporting the structure of the industrial scanner and dust-proofing inside the scanner. The rigid frame 40 is provided with a number of slide rails, and the slide rails are groove-shaped tracks arranged on the support beams of the rigid frame 40.

[0034] In this embodiment, the first moving rod 21 is provided with side guide grooves. The side guide grooves are of a double-groove structure and are located on both side surfaces of the first moving rod 21. The scanning and sampling assembly 10 is equipped with pulleys and is embedded in the side guide grooves of the first moving rod 21. The scanning and sampling assembly 10 is provided with a main frame in a convex shape. Two rows of symmetric pulleys are installed at the top of the frame and are located inside the frame. The pulleys are embedded in the side guide grooves of the first moving rod 21, and the scanning and sampling assembly 10 can move in the front-back direction.

[0035] In this embodiment, the industrial scanner is further provided with a hinge guide rail. A moving hinge 24 is embedded in the guide groove of the hinge guide rail. The moving hinge 24 is fixed to the scanning and sampling assembly 10. The hinge guide rail is fixed to the second moving rod 22. One end of the hinge is fixed to the scanning and sampling assembly 10, and the other end passes through the hinge guide rail and is connected to the motor. By pulling the hinge to tighten with the motor, the scanning and sampling assembly 10 is driven to slide forward. When the scanning and sampling assembly 10 slides backward, the hinge loosens.

[0036] On the industrial scanner of this embodiment, the first moving rod 21 and the second moving rod 22 are fixed by an L-shaped fixing member. The first moving rod 21 and the second moving rod 22 are on the same horizontal plane. Therefore, the scanning and sampling assembly 10 can only move in the front-back direction. At this time, the loading platform is horizontally placed on the sliding track, and the fixing member does not fix the loading platform. The scanning personnel can achieve the effect of comprehensively scanning the items on the planar scanning table 30 by pushing the loading platform placed on the sliding track.

[0037] An industrial scanner for non-contact full-plane scanning proposed in the second embodiment of the present utility model can achieve the effect of fully scanning a large-plane workpiece on the planar scanning table 30 by using a moving guide rail to drive the scanning and sampling assembly 10 to move in the front-back direction in the horizontal plane and combining with the left-right sliding of the planar scanning table 30.

[0038] The basic features, principles, and advantages of the present utility model have been shown and described above. It should be noted that the present utility model is not limited to the above embodiments, but only some embodiments. Without departing from the spirit and scope of the present utility model, several improvements and supplements made are regarded as within the protection scope of the present utility model.
