The moving directions of the limiting assembly 2 and the detecting assembly 3 can be opposite, for example, before the product is placed on the supporting platform, the limiting assembly 2 moves towards the product, and the distance from the limiting assembly 2 to the product is smaller than the distance from the detecting assembly 3 to the product. The product can be fed by a manipulator and can be a liquid crystal panel. After carrying out the material loading through the manipulator, because spacing subassembly 2 shifts in place before the material loading prerequisite, laminate liquid crystal display panel earlier with spacing subassembly 2 through the manipulator this moment, precision when guarantee liquid crystal display panel tentatively places.

After the product is placed and is accomplished, detecting component 3 can remove to the product direction, and spacing subassembly 2 keeps motionless or removes to the direction of keeping away from the product, and after detecting component 3 contacted the product, detecting component 3 can detect the product.

The first driving mechanism 4 may be a cylinder, a motor, etc., the first connecting member 11 may be mounted on the fifth connecting member 13, and the first connecting member 11 may be slidably connected with the fifth connecting member 13. The first driving mechanism 4 can drive the first connecting piece 11 to move towards the direction close to or away from the product, and when the first connecting piece 11 moves, the limiting component 2 and the detecting component 3 on the first connecting piece 11 move together, so that liquid crystal panels with different sizes can be adapted.

Because the material loading degree of depth of material loading manipulator is limited, to the less liquid crystal display panel of size, after the material loading, spacing subassembly 2 probably can't laminate with liquid crystal display panel, and detecting element 3 also can't detect liquid crystal display panel. At this time, the first driving mechanism 4 drives the first connecting piece 11 to move towards the liquid crystal panel, so that the moving distance between the limiting component 2 and the detecting component 3 is effectively increased, and the liquid crystal panels with different sizes can be detected conveniently.

As shown in fig. 1, a screw 41 is disposed at a driving end of the first driving mechanism 4, a second connecting member 12 is disposed on the first connecting member 11, a through hole is disposed on the second connecting member 12, and the screw 41 is inserted into the through hole and is in threaded connection with the second connecting member 12 through the through hole.

There is a region at the edge of the liquid crystal panel which is in contact with the probe 33, and the first direction may be the direction of the Z-axis in the figure, and when the inspection is required, the inspection unit 3 is moved to the edge of the liquid crystal panel. The edge of the liquid crystal panel is located between the upper cover plate 31 and the lower cover plate 32, both the upper cover plate 31 and the lower cover plate 32 can move towards the liquid crystal panel until the upper cover plate 31 is attached to the upper surface of the liquid crystal panel, and the probe 33 on the lower cover plate 32 is attached to the lower surface of the liquid crystal panel. At this time, the liquid crystal panel can be lighted, and whether the dark spot exists or not can be detected, so that the quality of the liquid crystal panel can be judged.

As shown in fig. 1, the supporting platform further includes a second driving mechanism 5, the second driving mechanism 5 is installed on the first connecting member 11, the second driving mechanism 5 is respectively connected to the upper cover plate 31 and the lower cover plate 32 in a driving manner, and the second driving mechanism 5 is adapted to drive the upper cover plate 31 and the lower cover plate 32 to move along the first direction.

The second driving mechanism 5 may be an air cylinder, and may have two moving blocks thereon, and the moving directions of the two moving blocks may be opposite, and the distance of each moving of the two moving blocks may also be kept the same, and the upper cover plate 31 and the lower cover plate 32 are respectively installed on one of the moving blocks. Therefore, when the upper cover plate 31 and the lower cover plate 32 are driven to move by the air cylinder, the upper cover plate 31 and the lower cover plate 32 synchronously contact the liquid crystal panel and leave the liquid crystal panel, and the detection quality of the liquid crystal panel is guaranteed.

As shown in fig. 1, the supporting platform further includes a third driving mechanism 6, the third driving mechanism 6 is mounted on the first connecting member 11, the third driving mechanism 6 is in driving connection with the second driving mechanism 5, and the third driving mechanism 6 is adapted to drive the second driving mechanism 5 to move along the first direction.

The first direction may be a direction of a Z axis in the drawing, the third driving mechanism 6 may be a linear motor, the accuracy of the linear motor is high, and the second driving mechanism 5 is driven by the linear motor to move along the first direction. The positions of the upper cover 31 and the lower cover 32 on the second drive mechanism 5 with respect to the liquid crystal panel can thereby be adjusted.

Since the thicknesses of the liquid crystal panels are different, for the liquid crystal panels with different thicknesses, the third driving mechanism 6 is required to drive the second driving mechanism 5 and the upper cover plate 31 and the lower cover plate 32 thereon to move along the first direction, so that the distance from the upper cover plate 31 to the upper surface of the liquid crystal panel and the distance from the lower cover plate 32 to the lower surface of the liquid crystal panel are kept consistent. Therefore, when the liquid crystal panel is detected, normal contact between the probe 33 and the liquid crystal panel can be guaranteed, and damage to the probe 33 is avoided.

As shown in fig. 2, the supporting platform further includes a third connecting member 7, a fourth driving mechanism 8 and a fifth driving mechanism 9, the fourth driving mechanism 8 is installed on the third connecting member 7, the third connecting member 7 is connected to the first connecting member 11, the fourth driving mechanism 8 is connected to the upper cover plate 31 in a driving manner, the fourth driving mechanism 8 is adapted to drive the upper cover plate 31 to move along the first direction, the fifth driving mechanism 9 is installed on the first connecting member 11, the fifth driving mechanism 9 is connected to the lower cover plate 32 in a driving manner, and the fifth driving mechanism 9 is adapted to drive the lower cover plate 32 to move along the first direction.

The first direction may be a direction of a Z axis in the drawing, the upper cover 31 may be independently driven by the fourth driving mechanism 8, and the fourth driving mechanism 8 may be an air cylinder, thereby controlling the upper cover 31 to move closer to or away from the upper surface of the liquid crystal panel. The lower cover 32 may be independently driven by a fifth driving mechanism 9, and the fifth driving mechanism 9 may be an air cylinder, thereby controlling the lower cover 32 to move toward or away from the lower surface of the liquid crystal panel.

Since the upper cover plate 31 and the lower cover plate 32 are controlled by one cylinder at the same time, the two cover plates need to move synchronously, so that alignment needs to be performed in advance, and the distance from the upper cover plate 31 to the upper surface of the liquid crystal panel and the distance from the lower cover plate 32 to the lower surface of the liquid crystal panel are kept consistent before detection, which requires a long time for alignment. And through two cylinders independent control upper cover plate 31 and lower cover plate 32 respectively, the user can independent control upper cover plate 31 or the displacement distance of lower cover plate 32 to reduce the counterpoint time, improve detection efficiency.

As shown in fig. 2, an opening 321 is formed in the lower cover plate 32, and the opening 321 is used for avoiding the third connecting member 7 and the fourth driving mechanism 8 when moving.

The axial direction of the opening 321 is the direction of the Z axis, and when the upper cover plate 31 and the lower cover plate 32 are simultaneously moved toward the product, the third connecting member 7 is located in the opening 321, and the third connecting member 7 is moved in the Z axis direction. Through the arrangement of the opening 321, the detection assembly 3 can be ensured to be attached to the surfaces of the upper cover plate 31, the lower cover plate 32 and the liquid crystal panel when detecting a thin liquid crystal panel.

As shown in fig. 1 and 3, the supporting platform further includes a sixth driving mechanism 10, the sixth driving mechanism 10 is installed on the first connecting member 11 or the fifth connecting member 13, the sixth driving mechanism 10 is in driving connection with the position limiting assembly 2, and the sixth driving mechanism 10 is adapted to drive the position limiting assembly 2 to move toward or away from the product.

In one embodiment, the sixth driving mechanism 10 may be a cylinder, and the cylinder may be fixed to the first connecting member 11 and move toward the product direction together with the first connecting member 11. Therefore, the moving distance of the limiting component 2 can be increased, and the liquid crystal panels with different sizes can be positioned. The cylinder can also simultaneously drive the stopper to move continuously towards or away from the product relative to the first connecting piece 11.

In another embodiment, the cylinder may be fixed to the fifth link 13, and the position of the cylinder may be maintained as the first link 11 moves toward the product. The cylinder can actuate the stopper to now continue to move towards or away from the product with respect to the fifth link 13.

As shown in fig. 1, the limiting assembly 2 includes a fourth connecting member 21, an elastic member 22 and a limiting block 23, the sixth driving mechanism 10 is drivingly connected to the fourth connecting member 21, the limiting block 23 is slidably connected to the fourth connecting member 21, the elastic member 22 is respectively connected to the fourth connecting member 21 and the limiting block 23, and the elastic member 22 is used for resetting the limiting block 23 after moving relative to the fourth connecting member 21.

The limiting block 23 can be attached to the liquid crystal panel, and since the liquid crystal panel is taken and placed by the manipulator of the preorder process, the movement of the manipulator has a movement error, so that the liquid crystal panel is prevented from being damaged. When the manipulator moves excessively towards the direction of the limiting component 2, the liquid crystal panel thereon can push the limiting block 23 towards the direction of the fourth connecting piece 21, so as to prevent the liquid crystal panel from being damaged due to hard contact between the liquid crystal panel and the limiting block 23. Before detection, after the position of the liquid crystal panel is corrected or the liquid crystal panel is taken away, the elastic piece 22 can drive the limiting block 23 to reset, and the limiting block 23 is convenient to position the next liquid crystal panel to be detected.

As shown in fig. 1, the limiting component 2 further includes a roller structure 24, the roller structure 24 is rotatably connected to the limiting block 23, and the roller structure 24 is adapted to rotate around a first direction. The roller structure 24 may contact the liquid crystal panel, and since the manipulator has a certain error when placing the liquid crystal panel, a clamping mechanism is subsequently required to finely adjust the position of the liquid crystal panel. When the position of the liquid crystal panel is adjusted, the roller structure 24 can be ensured, the roller structure 24 can be driven to rotate by the part, attached to the roller structure 24, of the edge of the liquid crystal panel, and therefore the edge of the liquid crystal panel is prevented from being damaged by friction.
