Description

Technical Field

[0001] The present invention relates to the technical field of photosensitive equipment, and in particular to a housing for photosensitive equipment, a photosensitive device and applications. Background Art

[0002] A photosensitive device is a device that can sense light signals from external objects and convert them into electrical signals to obtain image information of the object, such as smart cameras and barcode readers. The photosensitive device can process the image information to obtain the content of the one-dimensional or two-dimensional code in the image, or the position (or coordinates) of the target of interest in the image, or the content of the characters in the image (optical character recognition or OCR). Therefore, the photosensitive device has a window for receiving light signals from external objects.

[0003] Photosensitive devices are usually installed on automated equipment or production lines. In some industrial production lines or automated equipment, the space for installing photosensitive devices is limited. However, this limitation is sometimes longitudinal and sometimes transverse. When installing, the window of the photosensitive device needs to face the object being photographed. Therefore, there are two types of designs for existing photosensitive devices. One is a longitudinal design, that is, the direction of the window of the photosensitive device is consistent with the direction of the main axis of the product; the other is a transverse design, that is, the direction of the window of the photosensitive device is at a certain angle to the direction of the main axis of the product (usually greater than 45°). The industrial site will choose which type of design product to install based on the actual situation.

[0004] The inventors found that in order to meet the needs of the above-mentioned industrial sites, two products must be designed, which leads to higher costs on the one hand, and more importantly, inconvenience in on-site use, especially when the on-site space changes. Summary of the invention

[0005] The purpose of the present invention is to overcome the above-mentioned deficiencies of the prior art and to provide a housing for a photosensitive device, in which two types of designs of the photosensitive device can be integrated into one housing, thereby reducing production costs.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] A housing for a photosensitive device comprises a detachably connected shell and a front cover, wherein a first end face of the shell used for connecting to the front cover is arranged at an angle relative to an axis of the shell, an end face of one end of the front cover used for connecting to the shell is a second end face matching the first end face, the first end face and the second end face are centrally symmetrical figures, and the other end face of the front cover has a window mounting surface arranged at an angle to the second end face, and a transparent window is installed on the cover wall of the front cover where the window mounting surface is located.

[0008] The front cover can be installed on the shell after being rotated 180 degrees relative to the symmetric center line of the first end face and the second end face, so as to realize the change of the angle between the axis of the transparent window and the axis of the shell.

[0009] Furthermore, a plurality of positioning grooves are provided at the first end face of the shell, and a positioning boss matching the positioning grooves is provided at the second end face of the front cover, or a plurality of positioning bosses are provided at the first end face of the shell, and a plurality of positioning grooves matching the positioning bosses are provided at the second end face of the front cover.

[0010] The positioning boss can be inserted into the positioning groove to position the installation of the shell and the front cover. The positioning groove and the positioning boss are arranged so that after the front cover is rotated 180° relative to the symmetry center of the second end face, the positioning boss can still be inserted into the positioning groove.

[0011] Furthermore, the positioning groove is arranged at a middle position of the edge of the end surface, or is symmetrically arranged relative to the middle position of the edge of the end surface, and the arrangement position of the positioning boss matches the positioning groove.

[0012] Furthermore, a sealing ring is provided between the shell and the front cover for sealing the gap between the shell and the front cover.

[0013] Furthermore, the included angle between the first end face and the axis of the shell is 20°-70°, and the included angle between the window mounting surface and the second end face is 20°-70°.

[0014] Furthermore, the end surface of the front cover located on the side facing the second end surface includes a window mounting surface and a closing surface, and a closing plate is installed on the cover wall of the front cover where the closing surface is located, and a flexible circuit board is installed on the closing plate.

[0015] The invention also discloses a photosensitive device, which adopts the photosensitive device housing.

[0016] The invention also provides a production line equipped with the photosensitive device.

[0017] Furthermore, the photosensitive device includes a first photosensitive device and a second photosensitive device. The shell axis of the first photosensitive device is vertically arranged to place the detected object, and the transparent window is parallel to the detected object placement mechanism. The shell axis of the second photosensitive device is parallel to the detected object placement mechanism, and the transparent window is arranged at an angle to the detected object placement mechanism. The front cover of the first photosensitive device is rotated 180° and installed to the shell, so as to obtain the second photosensitive device.

[0018] Furthermore, the first photosensitive device is arranged between two obstacles above the detected object placement mechanism, and the second photosensitive device is arranged between the detected object placement mechanism and the obstacle above the detected object placement mechanism.

[0019] Beneficial effects of the present invention:

[0020] 1. The photosensitive device of the present invention can realize two orientation settings of the transparent window by rotating the front cover 180 degrees. One product realizes the functions of two traditional photosensitive device products, greatly reducing the design cost.

[0036] As introduced in the background technology, the existing photosensitive devices require two types of designs, which have high design costs and high production costs. To address the above problems, the present application proposes a housing for a photosensitive device.

[0037] In a typical implementation example 1 of the present application, Figure 1-4 As shown, a housing for a photosensitive device includes a shell 1 and a front cover 2 that are detachably connected.

[0038] The shell and the front cover are both structures with one end open, with a cavity inside for installing other equipment, one end of the shell has a first end face 1-1 for connecting to the front cover, and one end of the front cover has a second end face 2-1 for connecting to the shell, the second end face matches the shape of the first end face, and the first end face is inclined at an acute angle to the axis of the shell.

[0039] In this embodiment, the first end face is a rectangle, and the second end face is also a rectangle matching the first end face.

[0040] The first end face may also adopt other centrally symmetrical shapes such as square, circle, ellipse or diamond, and the second end face may also adopt a shape matching the first end face, as long as the front cover can still be assembled to the shell after being rotated 180° along the center of symmetry of the second end face. Technical personnel in this field can select the shapes of the first end face and the second end face according to actual needs, which will not be described in detail here.

[0041] In this embodiment, the shell is in the shape of a cuboid, and its first end face is in the shape of a rectangle. The shell includes a bottom shell wall and side shell walls arranged at four edges of the bottom shell wall. The axis of the shell refers to an axis perpendicular to the bottom shell wall, and the axis of the shell is a line passing through the center of the bottom shell wall and perpendicular to the bottom shell wall.

[0042] The shell can also be configured as a cube of other shapes such as a cylinder, an elliptical cylinder, etc. according to the shape of the first end face. Those skilled in the art can configure it according to actual needs, which will not be described in detail here.

[0043] In this embodiment, a plurality of positioning grooves 1-2 are provided at the edge of the first end surface, and a plurality of positioning bosses 2-2 matching the positioning grooves are provided at the edge of the second end surface of the front cover. The positioning bosses can be inserted into the positioning grooves to limit the installation of the shell and the front cover.

[0044] The positioning groove may also be provided at the edge of the second end surface of the front cover, and the positioning boss may be provided at the edge of the first end surface.

[0045] The positioning groove and the positioning boss should be arranged at positions such that after the front cover is rotated 180° relative to the symmetry center of the second end surface, the positioning boss can still be inserted into the positioning groove.

[0046] In this embodiment, the positioning groove is arranged in the middle of two opposite edges of the first end surface, and matching therewith, the positioning boss is arranged in the middle of two opposite edges of the second end surface.

[0047] Those skilled in the art may also arrange the positioning groove at the edge of the second end surface and the first boss at the edge of the first end surface according to actual needs.

[0048] In another embodiment, a plurality of positioning grooves may be respectively provided on two opposite edges of the first end surface, and the positioning grooves are symmetrically distributed relative to the center positions of the edges.

[0049] Those skilled in the art may set the positions of the positioning grooves and the positioning bosses according to actual needs, which will not be described in detail here.

[0050] The first end surface is provided with a threaded hole 1-3, and the front cover is provided with a through hole 2-3 matching the threaded hole. The front cover and the housing are detachably connected via the threaded hole, the through hole and the fixing bolt.

[0051] The threaded hole is opened at the edge of the first end surface, and the through hole is opened at the edge of the front cover. The specific positions of the through hole and the threaded hole can be selected and set according to actual needs.

[0052] The front cover and the housing may also be connected in other detachable ways such as plug-in, and those skilled in the art may make settings according to actual needs, which will not be described in detail here.

[0053] The end face facing the side of the second end face of the front cover includes a window mounting face and a closing face, the window mounting face is inclined at an acute angle relative to the second end face, and the window mounting face and the closing face are symmetrically arranged relative to the symmetry plane of the second end face, a transparent window 3 is installed on the cover wall of the front cover where the window mounting face is located, the transparent window can be integrally connected to the cover wall of the front cover, or can be detachably connected, a closing plate 4 made of non-transparent material is installed on the cover wall of the front cover where the closing face is located, the closing plate can be integrally connected to the cover wall of the front cover, or can be detachably connected, and technical personnel in this field can make arrangements according to actual needs, a flexible circuit board is installed on the cover wall of the front cover where the closing face is located, the flexible circuit board is installed on the sealing plate, and is used to install LED lights, buttons and other components.

[0054] The front cover wall portion where the window installation surface and the closing surface are located is protruded relative to the front cover wall portion where the through hole is located, which can increase the internal space of the front cover without using longer fixing bolts.

[0055] Preferably, a sealing ring 5 is provided between the first end face and the second end face. The sealing ring is arranged along the edge of the first end face and the second end face, avoiding the positions of threaded holes, through holes, positioning grooves and positioning bosses, and is used to seal the gap between the front cover and the shell to play a dust-proof and waterproof role.

[0056] In this embodiment, the angle α between the first end face and the axis of the shell is 20°-70°, and the angle β between the window installation surface and the second end face is 20°-70°. The setting of the angles between the first end face and the axis of the shell, and between the window installation surface and the second end face enables the shell to have two working modes, one of which is that when the front cover is installed on the shell, the axis of the transparent window is parallel or approximately parallel to the axis of the shell, and the angle between the axis of the transparent window and the axis of the shell is less than 30°, and the other working mode is to remove the front cover in the first working mode, rotate 180° relative to the symmetry center of the second end face, and then install it on the shell, at which time the angle a between the axis of the transparent window and the axis of the shell is 60°-120°.
