The annular recess is generally arranged to be narrow enough to support the LCD screen product 6.

Referring to fig. 4, as a further preferred scheme, a reinforcing side wall 33 is arranged on one side of the jig 3 away from the annular groove 32, the reinforcing side wall 33 is arranged on the outer side of the jig 3, and a circle is arranged on the outer side of the jig 3, so that the strength of the jig 3 can be improved, when the area of the LCD screen product 6 is large, the relatively thin jig 3 also has sufficient strength, and the stability and reliability of the LCD screen product 6 mounted on the jig 3 are ensured.

Referring to fig. 1, the backlight 4 is preferably a surface light source, i.e. a light source emitting light on the whole surface, so that the whole backlight 4 emits light more uniformly, and the visual inspection mechanism 2 is easier to photograph light leakage; the backlight 4 may be an LED backlight commonly used in the art. The appearance of backlight 4 is unanimous with the appearance of through-hole 31, the area of backlight 4 is big than the area of through-hole 31 to guarantee that through-hole 31 on the tool 3 can be by the luminous cover of backlight 4, when LCD screen product 6 was placed on tool 3, all had the light leak to produce when there is the gap in the optional position between through-hole 31 and LCD screen product 6, make that visual detection mechanism 2 detects more accurate. The back of the backlight source 4 is preferably provided with a heat radiation fin 41 for radiating the light source of the backlight source 4, so that the service life of the light source of the backlight source 4 is prolonged, and the service life of the LCD product positioning and placing device with the dislocation detection function is prolonged; for example, when the light source of the backlight 4 is an LED lamp, the heat dissipation of the LED lamp can be enhanced by the heat dissipation fins 41, so that the service life of the LED lamp is greatly prolonged.

Referring to fig. 1, visual detection mechanism 2 activity sets up on support 1, visual detection mechanism 2 position on support 1 can be adjusted to can remove visual detection mechanism 2 to different positions, carry out image recognition to different positions on tool 3 and detect, whether the accurate placing of LCD screen product 6 that adapts to different appearances detects at tool 3. A sliding rod can be arranged on the support 1, the visual detection mechanism 2 is arranged on the sliding rod in a sliding mode, and the movement position of the visual detection mechanism 2 can be driven by driving mechanisms such as a single-shaft mechanical arm. To general rectangular LCD screen product 6, can fix and set up two sets of visual detection mechanism 2, two sets of visual detection mechanism 2 set up along rectangular LCD screen product 6 long direction to can shoot the position between whole rectangular LCD screen product 6 and the tool 3 with two sets of LCD screen products 6, make through rectangular LCD screen product 6 of disposable detection of two sets of visual detection mechanism 2, improve the efficiency of test from this.

Referring to fig. 1, the vision inspection mechanism 2 includes a camera 21 and a lens 22, the camera 21 is movably or fixedly disposed on the bracket 1, and the lens 22 is mounted on the camera 21. The camera 21 may be a CCD camera, and the lens 22 may be selected as needed, or a wide-angle lens may be used.

When the LCD product positioning and placing device with the dislocation detection function of the embodiment is used, the LCD screen product 6 is fed into the annular groove 32 of the jig 3 by using a manipulator or other feeding structure; then, the jig 3 with the LCD screen product 6 is placed on the bracket 1 at a position between the visual detection mechanism 2 and the backlight source 4; then, the backlight source 4 is started, whether light leakage exists between the outer side of the LCD screen product 6 and the jig 3 is detected through the visual detection mechanism 2, if the light leakage exists, the LCD screen product 6 is placed in the jig 3 in a staggered mode, further manual correction or mechanical hand correction is needed, if the light leakage does not exist, the LCD screen product 6 is accurately placed on the jig 3, and the LCD screen product 6 can be transferred to a subsequent production detection station along with the jig 3 for further production and processing.

Whether the specific LCD screen product 6 is accurately placed on the jig 3 can be specifically judged by the following method:

grade one:

if a lightening area is arranged at the upper left corner between the outer side of the LCD screen product 6 and the jig 3, the LCD screen product 6 is directly judged to be placed on the jig 3 in a staggered manner;

if a lightening area is arranged at the lower left corner between the outer side of the LCD screen product 6 and the jig 3, the LCD screen product 6 is directly judged to be placed on the jig 3 in a staggered manner;

if two bright lines appear on the upper side or the right side of the upper right corner between the outer side of the LCD screen product 6 and the jig 3, the LCD screen product 6 is directly judged to be placed on the jig 3 in a staggered manner;

if two bright lines appear at the lower edge of the right lower corner between the outer side of the LCD screen product 6 and the jig 3 or the right edge, the LCD screen product 6 is directly judged to be placed on the jig 3 in a staggered manner;

grade two:

fifthly, if the semicircle at the upper right corner between the outer side of the LCD screen product 6 and the jig 3 is bright and if the upper boundary line between the outer side of the LCD screen product 6 and the jig 3 is covered or the right boundary line is covered, the LCD screen product 6 is judged to be placed on the jig 3 in a staggered way; if one of the products is not true, the LCD screen product 6 is accurately placed on the jig 3.

And if the phenomenon in the grade one does not occur, further judging through the grade two.

Except that the LCD screen products 6 are judged to be placed on the jig 3 in a staggered mode under the conditions, the LCD screen products 6 are judged to be accurately placed on the jig 3 under other conditions.
