Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

As shown in fig. 1-5, an embodiment of the present utility model provides a back plate detection device 100, where the back plate detection device 100 includes a base 110, a limiting member 120, a light emitting member 130, and a detection camera 140.

The base 110 is used for supporting the limiting member 120, the light emitting member 130, the detection camera 140, and the like.

The limiting member 120 is disposed on the base 110, and the limiting member 120 is used for limiting the back plate 150, i.e. the limiting member 120 can fix the back plate 150 to limit the movement of the back plate 150.

The light emitting element 130 is located between the base 110 and the back plate 150, the light emitting element 130 is disposed corresponding to the mounting hole 110c of the back plate 150, if the mounting hole 110c has the rivet 151, the light emitted by the light emitting element 130 cannot pass through the mounting hole 110c, if the mounting hole 110c is not riveted, and if the mounting hole 110c has no rivet 151, the light emitted by the light emitting element 130 can pass through the mounting hole 110c. The mounting holes 110c are typically formed in the periphery of the back plate 150, but the positions of the mounting holes 110c may vary with respect to the base 110 due to the different sizes of the back plate 150.

When the light emitting element 130 is movably disposed on the base 110, the light emitting element 130 can be aligned with the mounting holes 110c of different positions on the back plate 150 of different models, so as to adapt to the back plate 150 of different sizes. It is understood that the light emitting element 130 on the back plate 150 can move linearly or curvilinearly relative to the base 110, and only the light emitting element 130 can be aligned with the mounting holes 110c at different positions.

The detecting camera 140 is disposed on a side of the back plate 150 facing away from the light emitting element 130, that is, the light emitting element 130 and the detecting camera 140 are respectively located on two sides of the back plate 150. The detecting camera 140 is used for shooting the mounting hole 110c of the back plate 150 to detect whether the mounting hole 110c of the back plate 150 transmits light, and if the mounting hole 110c of the back plate 150 transmits light, the mounting hole 110c is indicated to be rivet-missing.

By detecting the mounting hole 110c by the detection camera 140, the detection speed and accuracy can be improved compared to using the human eye detection.

In summary, the positions of the mounting holes 110c of the back plates 150 of different models are different, and since the light emitting element 130 can move on the base 110, the light emitting element 130 can be aligned to the mounting holes 110c of different positions by adjusting the position of the light emitting element 130 relative to the base 110, so that the detection device can adapt to the back plates 150 of different sizes.

At least one of the second light bar 132 and the first light bar 131 can move relative to the base 110 to accommodate different sizes of back plates 150. For example, the first light bar 131 is fixed, the second light bar 132 is movable, and when the back plate 150 is placed on the base 110, one side of the back surface is aligned with the first light bar 131 based on the first light bar 131, and then the second light bar 132 is moved so that the second light bar 132 is aligned with the other side of the back plate 150, thereby adapting to the back plate 150 of different sizes. For another example, the first light bar 131 may be movable, the second light bar 132 may be movable, and the back plate 150 may be placed at a position of the base 110 more flexibly.

With continued reference to fig. 5, in some embodiments, the light emitting device 130 further includes a third light bar 133, where the third light bar 133 is disposed on the base 110 and the third light bar 133 extends along a second direction YY, which is perpendicular to the first direction XX, and the second direction YY may be an extending direction of another set of opposite sides of the back plate 150. In this embodiment, the three sides of the back plate 150 are all provided with the mounting holes 110c, the third light bar 133 and the first light bar 131 are respectively disposed corresponding to two adjacent sides of the back plate 150, and at this time, the third light bar 133 and the second light bar 132 are also respectively disposed corresponding to two adjacent sides of the back plate 150, that is, the first light bar 131, the second light bar 132 and the third light bar 133 can respectively detect the three sides of the back plate 150. The third light bar 133 may be slidably disposed on the base 110, or the third light bar 133 may be fixedly disposed on the base 110.

As shown in fig. 5-8, in some embodiments, the base 110 is provided with a first chute 110a and a second chute 110b, and the back plate detection device 100 further includes a first sliding member 160, a first locking member 170, a second sliding member 180, and a second locking member 190. The first slider 160 is slidably disposed in the first chute 110a, and the first light bar 131 is disposed in the first slider 160, and the first light bar 131 is slidably disposed on the base 110 through the first slider 160. The first locking member 170 is disposed on the first slider 160, and the first locking member 170 can lock the first slider 160 to fix the first slider 160 to the base 110, thereby fixing the first light bar 131 to the base 110. When the first light bar 131 is adjusted, the first locking member 170 is released, then the first sliding member 160 is moved, so that the first light bar 131 is aligned to the mounting hole 110c on the corresponding side of the back plate 150, and finally the first sliding member 160 is locked by the first locking member 170, so as to avoid displacement of the first light bar 131.

The structure of the second slider 180 and the second locking member 190 may refer to the first slider 160 and the first locking member 170, the second slider 180 is slidably disposed in the second chute 110b, the second light bar 132 is disposed in the second slider 180, and the second light bar 132 is slidably disposed in the base 110 through the second slider 180. The second locking member 190 is disposed on the second slider 180, and the second locking member 190 can lock the second slider 180 to fix the second slider 180 to the base 110, thereby fixing the second light bar 132 to the base 110. When the second light bar 132 is adjusted, the second locking member 190 is released, then the second sliding member 180 is moved, so that the second light bar 132 is aligned to the mounting hole 110c on the corresponding side of the back plate 150, and finally the second sliding member 180 is locked by the second locking member 190, so as to avoid the second light bar 132 from shifting.

The first slider 160 and the second slider 180 may be sliding columns, and the first locking member 170 and the second locking member 190 may be nuts, which are screwed with the sliding columns, so as to compress the sliding columns on the base 110.

With continued reference to fig. 5, in some embodiments, the first light bar 131 is movable in a third direction ZZ relative to the base 110 such that the first light bar 131 is adjacent to or remote from the back plate 150 in the third direction ZZ, and the second light bar 132 is movable in the third direction ZZ relative to the base 110 such that the second light bar 132 is adjacent to or remote from the back plate 150 in the third direction ZZ. The third direction ZZ is perpendicular to the first direction XX and the second direction YY at the same time, i.e. the third direction ZZ may be the thickness direction of the back plate 150. By adjusting the distance between the first light bar 131 and the second light bar 132 and the back plate 150, the first light bar 131 and the second light bar 132 are close to the back plate 150 as much as possible, and when the mounting hole 110c of the back plate 150 is in rivet leakage, the light transmitted by the mounting hole 110c is brighter, thereby being beneficial to shooting by the detection camera 140.

As shown in fig. 5 and 6, in some embodiments, the limiting member 120 includes a plurality of first limiting rods 121, and the first limiting rods 121 may be disposed on the periphery of the back plate 150 and connected to the outer side Zhou Xiangdi of the back plate 150 to limit the movement of the back plate 150 along the first direction XX and the second direction YY. At least a portion of the first limiting rod 121 is movably disposed on the base 110 to accommodate the back plate 150 with different sizes, for example, at least a portion of the first limiting rod 121 may be slidably disposed on the base 110. Further, an end of the first limiting rod 121 remote from the base 110 may be bent to form a flare, so that the back plate 150 is easily guided to be placed between the plurality of first limiting rods 121.

As shown in fig. 6, in some embodiments, the base 110 is provided with a plurality of mounting holes 110c, the number of mounting holes 110c is greater than the number of first limiting rods 121, and at least a portion of the first limiting rods 121 can be plugged into the plurality of mounting holes 110c so that the portion of the first limiting rods 121 can move relative to the base 110. That is, in the first stopper rods 121 of which the portion is movable, each of the first stopper rods 121 has a plurality of mounting holes 110c corresponding thereto, and since each of the mounting holes 110c is positioned differently on the base 110, when the first stopper rod 121 is engaged with the different mounting hole 110c, it is equivalent to the movement of the first stopper rod 121 with respect to the base plate 134. By the first stopper rod 121 being fitted with the mounting hole 110c, the positional accuracy of the first stopper rod 121 can be improved.

As shown in fig. 4 and 5, in some embodiments, the back plate 150 is provided with a positioning hole, the limiting member 120 further includes a second limiting rod 122, the second limiting rod 122 is disposed on the base 110, and the second limiting rod 122 is in plug-in fit with the positioning hole to limit the back plate 150. The second limiting rod 122 can further limit the back plate 150, so as to improve the limiting performance. In addition, the second limiting rod 122 can distinguish between different types of the back plate 150, for example, different types (including the same size and different sizes) of the back plate 150, and the positioning holes are different, so that the position of the second limiting rod 122 needs to be adjusted to place the corresponding back plate 150 on the base 110.

As shown in fig. 6, in some embodiments, each light bar of the lighting device 130 includes a substrate 134, a plurality of LED beads 135, and a controller.

The number of the LED beads 135 can be adjusted according to the size of the light emitting member 130, and the size of the light emitting member 130 can be adjusted relatively precisely due to the small size of the individual LED beads 135. For example, the number of the LED beads 135 is adjusted, so as to adjust the lengths of the first, second and third light bars 131, 132 and 133.

The controller is connected to each LED light bead 135 to control the LED light beads 135 at different positions to be turned on or off. It is understood that the first light bar 131 can adapt to different sizes of back plates 150, so that the length of the first light bar 131 is not shorter than the edge length of the largest size back plate 150 that can be adapted, and when the first light bar 131 is adapted to a smaller size back plate 150, the first light bar 131 is partially exposed outside the smaller size back plate 150, and at this time, the controller can control the LED light beads 135 on the first light bar 131 located at the exposed position to be extinguished. The controller can also control the brightness of each LED light bead 135, for example, the brightness of the LED light beads 135 can be changed according to the ambient brightness.
