The camera 2.1 is coaxial with the center of the plate surface of the cover plate 6 to be detected, and the lens direction of the camera 2.1 is toward the cover plate 6 to be detected located below the light source adjustment module 4. Figure 3As shown. The combined light source includes two parallel bar light sources 3, the light source direction of the bar light sources 3 is toward the opposite side edges of the cover plate 6 to be detected, and the two ends of the length direction of any of the bar light sources 3 exceed the two ends of the side edges of the cover plate 6 to be detected, so as to fully fill in the light for the side edges; in the embodiment, for the detection device of this scheme, the combined light source is used to fill in the light for the four corners of the cover plate 6 to be detected, and the camera 2.1 takes a light picture of the cover plate 6 to be detected, so as to determine the collision of the four corners of the cover plate 6 to be detected according to the light and dark effects of the light picture.
[0036] Further integration Figure 3 The structure of the light source adjustment module 4 is described in detail as follows: the light source adjustment module 4 includes an adjustment plate 4.1, two first mounting plates 4.2 and four second mounting plates 4.3; the adjustment plate 4.1 is fixedly connected to the second slider 1.2 of the linear module 1, and the adjustment plate 4.1 has a wing plate extending along both sides perpendicular to the linear module 1, and a first mounting hole is arranged on the wing plate, and the extension direction of the first mounting hole is perpendicular to the linear module 1; the two first mounting plates 4.2 are respectively fixedly connected to the adjustment plate 4.1 through the first mounting hole in the direction from the wing plate away from the linear module 1; two second mounting holes are arranged on the first mounting plate 4.2 at intervals, and the extension direction of the second mounting holes is perpendicular to the first mounting hole. Extension direction; the positions of the four second mounting holes on the two first mounting plates 4.2 correspond to each other in pairs, and four second mounting plates 4.3 are fixed on the first mounting plate 4.2 through the four second mounting holes, and a mounting position for the strip light source 3 is formed between the two second mounting plates 4.3 installed on the two second mounting holes with corresponding positions; the second mounting plate 4.3 includes a first positioning plate surface and a second positioning plate surface 4.4 along the extension direction of the linear module 1, and the first positioning plate surface and the second positioning plate surface 4.4 are parallel; the second positioning plate surface 4.4 is used for positioning and installing the strip light source 3, and the first positioning plate surface is parallel to the first mounting plate 4.2 and is fixed to the first mounting plate 4.2 through the second mounting holes.
[0037] Optionally, when the placement angle of the cover plate 6 to be detected is different, the placement position of the combined light source can be dynamically adjusted; for example, when the placement state of the cover plate 6 to be detected is that its length direction is vertically extending away from the linear module 1, the strip light source 3 is adjusted to be parallel to the length direction of the cover plate 6 to be detected. At this time, the installation direction of the strip light source 3 can be changed by changing the plate surface direction of the second positioning plate surface 4.4 on the second mounting plate 4.3. For example, the first positioning plate surface and the second positioning plate surface 4.4 of the second mounting plate 4.3 are designed to be perpendicular to each other. At this time, when the first positioning plate surface is parallel to the first mounting plate 4.2 and fixed to the first mounting plate 4.2 through the second mounting hole, the second positioning plate surface 4.4 can position and install the strip light source 3 along the direction perpendicular to the length direction of the cover plate 6 to be detected, that is, a strip light source 3 installation position is formed between the second positioning plate surfaces 4.4 of the two second mounting plates 4.3 located on the same first mounting plate 4.2.
[0038] The two strip light sources 3 of the combined light source on the above-mentioned detection device are adjusted in installation size and installation spacing through the first and second installation holes.

For example, if the groove is set to a rectangular groove, a rectangular block structure is set at one end of the first mounting plate 4.2 close to the groove to increase its contact area with the adjustment plate 4.1 and improve the installation stability.
[0039] In order to facilitate the adjustment of the illumination angle of the strip light source 3, the adjustment is achieved by providing an arc groove on the positioning plate surface fixed to the strip light source 3. Specifically, an arc groove is provided on the second positioning plate surface 4.4 of the detection device, and the openings of the arc grooves of the two second positioning plate surfaces 4.4 located on the same first mounting plate 4.2 are oriented oppositely, and the arc grooves of the two second positioning plate surfaces 4.4 constituting the installation position of the strip light source are parallel in position and have corresponding shapes; the arc groove is used to flexibly connect the strip light source 3 to adjust the illumination angle of the strip light source. Optionally, as Figure 3 As shown, during installation, the strip light source 3 can be fixed by using a square-shaped clamping plate with openings at both ends. The size of the square-shaped clamping plate corresponds to the size of the strip light source installation position formed between the second mounting plate 4.3, and blocks engaging with the arc groove are provided on the corresponding two sides; after the strip light source 3 is fixed on the square-shaped clamping plate, the clamping plate is placed into the strip light source installation position, and the corresponding blocks on both sides of the clamping plate are moved to achieve adjustable fixation with the arc groove.

[0041] In order to improve the detection effect of the battery cover plate four-corner collision detection device, when installing the camera 2.1 and the strip light source 3, when any strip light source 3 in the combined light source is designed to irradiate the corresponding side of the cover plate 6 to be detected, the angle between the strip light source 3 and the vertical direction is 31°. At this time, the recognition effect of the four-corner collision of the cover plate 6 to be detected in the lighting picture obtained by taking the picture is the best; other parameters, such as the height of the camera 2.1, the height of the strip light source 3, etc., can be selected at different heights according to the type of cover plate; in the embodiment, the camera 2.1 is designed to be 360mm away from the cover plate surface, and the strip light source 3 is designed to be 310mm away from the cover plate surface.
