Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. Based on the embodiments of the present utility model, a person of ordinary skill in the art would be able to obtain all other embodiments based on the present application, which fall within the scope of the present utility model.

As described in the background art, when linear scanning or measurement is performed, the alignment of the linear laser module and the linear array camera needs to be adjusted respectively, so that the alignment of the linear laser module and the linear array camera can be realized, and the erection process of the linear array camera is complex.

In view of this, as shown in fig. 1 to 3, a line laser module 10 is proposed in a first aspect of the present application, and a line camera 90 is proposed in a second aspect of the present application. The mount 100 of the line laser module 10 is fixed on the housing 900 of the line camera 90, for example, may be fixed on the front cover 910 of the camera shown in fig. 1, and the light emitting surface of the line laser 200 is in the same direction as the lens 920. After installation, the linear light 30 projected by the line laser module 10 may be collinear with the photographing region 40 of the line camera 90.

Specifically, as shown in fig. 4 to 8, a line laser module 10 according to a first aspect of the present application includes a mounting base 100 and a line laser 200, wherein a mounting groove 130 is disposed on one side of the mounting base 100, and a plurality of first positioning members 111 are disposed on the other side opposite to the mounting groove 130. The line laser 200 is installed in the installation groove 130 for projecting the linear light 30 at the target area. The line L1 of the first positioning members 111 is parallel to the linear light 30 projected by the line laser 200. As shown in fig. 9 and 10, the case 900 of the line camera 90 is provided with a plurality of first stoppers 911, and a line L2 connecting the plurality of first stoppers 911 is parallel to the light sensing surface 930 of the line camera 90. The first positioning pieces 111 are used for being connected with the first limiting pieces 911 arranged on the housing 900 of the line camera 90 in a one-to-one correspondence manner so as to fix the mounting base 100 on the housing 900 of the line camera 90, and the light emitting surface of the line laser 200 is in the same direction with the direction of the lens 920.

In the embodiment of the present application, the mount 100 is provided with the plurality of first positioning members 111, and the connection line L1 of the plurality of first positioning members 111 is parallel to the linear light 30 projected by the line laser 200, so that after the plurality of first positioning members 111 are connected to the plurality of first limiting members 911, the connection line L2 of the plurality of first limiting members 911 is also parallel to the linear light 30 projected by the line laser 200. Since the connection line L2 of the first limiting members 911 is parallel to the photosurface 930, the linear light 30 projected by the line laser 200 is parallel to the photosurface 930, and thus, as shown in fig. 2 and 3, the linear light 30 projected by the line laser 200 may be parallel to the photographing region 40 aligned with the photosurface 930 and collinear with the center of the photographing region 40. Therefore, when the line camera 90 is erected, the line camera 90 is only connected with the first positioning piece 111 of the line laser module 10 through the first limiting piece 911, so that the shooting area 40 of the line camera 90 is collinear with the linear light 30 projected by the line laser module 10, and the relative positions of the line camera 90 and the line laser module 10 do not need to be additionally adjusted, thereby simplifying the erection process of the line camera 90 and realizing the rapid erection of the line camera 90.

In addition, in the embodiment of the present application, the linear light 30 projected by the line laser module 10 indicates the measured area, and the photographing area 40 is made to be collinear with the linear light 30, so that the photographing area 40 can be ensured to be consistent with the measured area. By mounting the line laser module 10 outside the line camera 90 housing 900, the space inside the line camera 90 can be eliminated. After the line camera 90 is erected, if the light of the detected area is sufficient, the line laser module 10 can be taken down, and the use is flexible and convenient.

The photosensitive surface 930 refers to a photosensitive area formed by a plurality of photosensitive units of the sensor plate, that is, the image sensor, and the reflected light from the imaging area 40 passes through the lens 920 of the line camera 90 and then forms an image on the photosensitive surface 930. Fig. 10 shows a partial projection view from the inside of the line camera 90 in the direction of the lens 920, wherein the structures located inside the line camera 90 are shown with solid lines and the structures located outside the camera front cover 910 are shown with dashed lines. As shown in fig. 10, the photosurface 930 of the linear camera 90 is a linear shape with a longer length and a narrower width, and the parallel of the connection line L2 of the first stoppers 911 on the housing 900 of the linear camera 90 and the photosurface 930 of the linear camera 90 means that the connection line L2 of the first stoppers 911 is parallel to the central line L3 of the photosurface 930, and the central line L3 of the photosurface 930 extends along the length direction of the photosurface 930.

In other embodiments of the present application, the line L1 of the first positioning members 111 is perpendicular to the linear light 30 projected by the line laser 200, and the line L2 of the first limiting members 911 is also perpendicular to the light sensing surface 930 of the line camera 90. Alternatively, the line L1 of the first positioning members 111 and the linear light 30 projected by the line laser 200 have an angle of 45 °, and the line L2 of the first positioning members 911 and the light sensing surface 930 of the line camera 90 also have an angle of 45 °. Alternatively, the line L1 of the first positioning members 111 and the linear light 30 projected by the line laser 200 have other predetermined angles of any degree, and the line L2 of the first limiting members 911 and the light sensing surface 930 of the line camera 90 also have the same predetermined angle of degree. The degree of the preset included angle is not limited, as long as the preset included angle between the connecting line L1 of the plurality of first positioning pieces 111 and the linear light 30 projected by the line laser 200 is the same as the preset included angle between the connecting line L2 of the plurality of first limiting pieces 911 and the light sensing surface 930 of the line camera 90, the linear light 30 projected by the line laser 200 is guaranteed to be parallel to the light sensing surface 930 after the plurality of first positioning pieces 111 are connected with the plurality of first limiting pieces 911.

In the first embodiment of the present application, the linear light 30 projected by the line laser 200 may be green light or red light, preferably green light.

In the first embodiment of the present application, the first positioning member 111 may be a positioning post, and the first limiting member 911 may be a limiting hole in plug-in fit with the positioning post. Thus, the first positioning member 111 and the first limiting member 911 have simple structures, and are convenient to manufacture.

In other embodiments of the present application, the first positioning member 111 may be a hole-like structure, and the first limiting member 911 may be a columnar structure. Alternatively, the first positioning member 111 and the first stopper 911 may be configured as other structures that can be fitted and connected. The present application is not limited in this regard.

In the first embodiment of the present application, as shown in fig. 11 to 14, the mounting base 100 of the line laser module 10 includes a mounting plate 110 and a mounting block 120 disposed on one side of the mounting plate 110, and the mounting groove 130 is located on the side of the mounting block 120 facing away from the mounting plate 110 and penetrates through the mounting block 120, so that the line laser 200 emits light toward the side facing away from the mounting plate 110. The first positioning piece 111 is located on a side of the mounting plate 110 facing away from the mounting block 120, and the mounting base 100 is used for mounting on a side of the line camera 90 where the lens 920 is disposed.

In the embodiment of the present application, the mounting block 120 is provided to conveniently accommodate the line laser 200, and the mounting plate 110 is provided to conveniently mount the mount 100 on the housing 900 of the line camera 90. The mounting groove 130 penetrates through one side of the mounting seat 100 facing away from the mounting plate 110, and the line laser 200 emits light toward one side facing away from the mounting plate 110, so that after the mounting seat 100 is mounted on one side of the line camera 90 where the lens 920 is disposed through the mounting plate 110, the light emitting direction of the line laser 200 can be in the same direction as the lens 920.

Further, as shown in fig. 12, the mounting groove 130 is coaxial with the optical axis of the line laser 200. As shown in fig. 13 and 14, the first positioning pieces 111 are provided in two, and the connecting line L1 of the two first positioning pieces 111 is coplanar with the axis L4 of the mounting groove 130. In this embodiment of the present application, two first positioning members 111 are provided, so that the line laser module 10 can be prevented from rotating relative to the line camera 90 after the first positioning members 111 are correspondingly connected with the first limiting members 911, and the connection difficulty between the line laser module 10 and the line camera 90 can be reduced. In a specific embodiment, the two first positioning members 111 may be symmetrically disposed about the axis of the mounting groove 130 to ensure uniform stress.

Further, the mounting base 100 is provided with at least one first magnetic positioning piece, and the first magnetic positioning piece is on the same side as the plurality of first positioning pieces 111 and is used for magnetically attracting with a second magnetic positioning piece on the inner side of the housing 900 of the line camera 90, so that the mounting base 100 is attracted to the outer surface of the housing 900 of the line camera 90. Therefore, when the line laser module 10 is installed, only the first positioning piece 111 and the first limiting piece 911 are required to be correspondingly connected, and then the installation plate 110 is required to be adsorbed on the shell 900 of the line camera 90, and the line laser module 10 can be directly taken down without polishing, so that the line laser module 10 is very convenient to install and detach.

Specifically, as shown in fig. 11, the first magnetic positioning element is a first magnet 700. As shown in fig. 14, the mounting plate 110 is provided with two first magnet grooves 114 on one side thereof where the first positioning members 111 are provided, and the first magnets 700 are mounted in the first magnet grooves 114. The two first magnet slots 114 are symmetrical about the line L1 connecting the two first positioning members. Therefore, each first magnet 700 and two first positioning members 111 can form a triangle stress structure, which is beneficial to improving the installation stability while being convenient for installation.

Accordingly, the second magnetic positioning element is a second magnet, as shown in fig. 10, the housing 900 of the linear camera 90 includes a front cover 910, two second magnet slots 912 are disposed on the inner surface of the front cover 910, the positions of the second magnet slots 912 correspond to the positions of the first magnet slots 114, and the second magnet is mounted in the second magnet slots 912. The two second magnet slots 912 are symmetrical about the line L2 connecting the two first stoppers 911.

In other embodiments of the present application, the number of the first magnet slots 114 may be greater, and accordingly, the number of the first magnets 700 and the second magnets may be greater. Other arrangements of the first magnet slots 114 are possible, and are not limited in this application.

In the first embodiment of the present application, since the mounting groove 130 is coaxial with the optical axis of the line laser 200 and the connecting line L1 of the two first positioning members 111 is coplanar with the axis L4 of the mounting groove 130, the connecting line L1 of the two first positioning members 111 is also coplanar with the optical axis of the line laser 200, so that the connecting line of the two first positioning members 111, the optical axis of the line laser 200 and the linear light 30 projected by the line laser 200 are coplanar, and thus, in the vertical direction, the two first positioning members 111 and the linear light 30 projected by the line laser 200 are located at the same height.

Accordingly, as shown in fig. 10, the connecting lines L2 of the first limiting members 911 on the housing 900 of the line camera 90 are flush with the photosurface 930 of the line camera 90. That is, the center lines L3 of the plurality of first stoppers 911 and the light sensing surface 930 of the line camera 90 are positioned at the same height, and thus, after the plurality of first stoppers 111 and the plurality of first stoppers 911 are connected, the linear light 30 projected by the line laser 200 may be parallel and collinear with the center line of the photographing region 40 aligned with the light sensing surface 930.

In other embodiments of the present application, the positions of the first positioning members 111 may be different from those shown in fig. 13 and 14, that is, the connecting line L1 of the two first positioning members 111 may not be coplanar with the axis L4 of the mounting groove 130, and in the vertical direction, the connecting line L1 of the two first positioning members 111 is at a distance from the axis L4 of the mounting groove 130. Accordingly, in the vertical direction, the same distance is also provided between the line L2 connecting the plurality of first stoppers 911 on the casing 900 of the line camera 90 and the center line L3 of the light sensing surface 930 of the line camera 90. Thus, after the plurality of first positioning members 111 and the plurality of first stopper members 911 are connected, it is possible to realize that the linear light 30 projected by the line laser 200 is parallel and collinear with the center line of the imaging region 40 aligned with the light sensing surface 930.

In a specific embodiment, the surface of the line laser 200 is cylindrical, thereby facilitating assembly and adjustment of the line laser module 10 during production. In the process of assembling the line laser module 10, it is generally necessary to rotationally adjust the circumferential angle of the line laser 200 by means of a structural tool, so that the line light 30 projected by the line laser 200 is parallel to the line L1 connecting the two first positioning members 111. Specifically, the structural fixture may include a line laser module mounting rack and a test board disposed on one side of the light emitting surface of the line laser 200 and having a certain distance from the line laser module 10. Two positioning grooves corresponding to the two first positioning pieces 111 of the line laser module 10 one by one are formed in one side surface of the line laser module mounting frame, and a datum line parallel to the connecting line of the two positioning grooves is formed in the test board. During adjustment, the line laser module 10 is firstly installed on a structural tool through a positioning groove, the line laser 200 is started, the linear light 30 emitted by the line laser 200 is projected onto a test board, and then the line laser 200 is rotated circumferentially, so that the linear light 30 projected by the line laser 200 can be overlapped with a datum line arranged on the test board, and the linear light 30 projected by the line laser 200 is parallel to a connecting line of the two first positioning pieces 111.

As shown in fig. 11, in the first embodiment of the present application, the line laser module 10 further includes a power supply module 300, and the power supply module 300 is connected to a side of the line laser 200 facing away from the light emitting direction through a cable 500, for supplying power to the line laser 200. Therefore, independent power supply of the line laser module 10 can be realized, power supply of other equipment is not needed, and the line laser module 10 is more flexible and convenient to use. Of course, in other embodiments, the line laser 200 may be electrically connected to the power supply circuit of the line camera 90 through a cable, with the power supply circuit of the line camera 90 powering the line laser 200.

As shown in fig. 12 and 13, the mounting block 120 is provided with a wire groove 140, the wire groove 140 extends from a side of the mounting block 120 facing away from the mounting plate 110 to the mounting plate 110, and the wire groove 140 communicates with the mounting groove 130 for receiving the cable 500. Thus, when the wire laser 200 enters the mounting groove 130, the cable 500 may enter through the wire groove 140 and be partially accommodated in the wire groove 140, so that the cable 500 may be conveniently accommodated.

As shown in fig. 11, the line laser module 10 further includes locking screws 600 provided on opposite side groove walls of the wire groove 140, the locking screws 600 being screwed into the screw holes in a direction perpendicular to the extending direction of the wire groove 140 to lock the notch of the wire groove 140. Since the wire groove 140 is provided with an opening at one side thereof and the wire groove 140 is communicated with the mounting groove 130, after the wire laser 200 is mounted to the mounting groove 130 and circumferentially adjusted, the notch of the wire groove 140 needs to be locked by the locking screw 600, so that the wire laser 200 can be locked, and the wire laser 200 is prevented from rotating circumferentially relative to the mounting groove 130, so that the linear light 30 projected by the wire laser 200 can be always parallel to the connecting line L1 of the plurality of first positioning members 111.
