Specifically, the carrier may be a tool tray that is moved on the conveyor line, or a carrier tray that can receive the display panel output by the conveyor line, and the like, and fixes the display panel in a uniquely determined posture; the detection device may be provided with a detection station at a location adjacent thereto, which may include a robotic arm or the like capable of carrying, lifting or securing the carrier so that the carrier carrying the display panel to be detected is positioned to a uniquely determined spatial position. As shown in fig. 1, the pressing device includes a transfer mechanism 1 and a pressing mechanism 2 disposed at a movable end of the transfer mechanism 1, the transfer mechanism can drive the pressing mechanism 2 to align with an adaptive pressing portion of a display panel to be detected, and then press the pressing mechanism 2 downward to light the display panel, the detection device obtains an image of the display panel after lighting by photographing, and identifies whether the display panel is a defective product based on the image.

It can be understood that, the crimping portions of the display panels with different sizes are different in size, and in order to adapt to the display panels with different sizes, the crimping mechanism 2 provided in this embodiment further includes a quick-change component 22 besides the pressure head 21 for crimping and lighting the display panels, referring to fig. 1 in combination with fig. 2, the quick-change component 22 is connected between the pressure head 21 and the movable end of the transfer mechanism 1, and includes at least two connecting portions 221, each connecting portion 221 can be respectively connected to the pressure heads 21 with different sizes, so that when detecting the display panels with different sizes, the adapted pressure head 21 is directly replaced and installed to the detection device by the corresponding connecting portion 221, and compared with the case where a plurality of detection devices adapted to the display panels with different sizes are simultaneously arranged, the occupation of the field space can be greatly reduced, and the device configuration cost can be saved.

In this embodiment, one end of the quick-change assembly 22 is fixedly connected to the movable end of the transferring mechanism 1, and the other end of the quick-change assembly is provided with a plurality of notches 2211, the plurality of notches 2211 are symmetrically distributed along a central axis, wherein a pair of symmetrical notches 2211 form the connecting portion 221; the pressing head 21 is screwed with a pair of knobs 211, and the rods of the knobs 211 can be respectively embedded in a pair of notches 2211 forming the same connecting portion 221, so that when the pressing head 21 is rotated to be abutted against the quick-change assembly 22, the solid part of the quick-change assembly 22, which is concavely provided with the notches 2211, is clamped between the head of the knob 211 and the outer wall of the pressing head 21, so that the pressing head 21 is locked on the quick-change assembly 22.

The pair of notches 2211 for forming the connecting portion 221 are symmetrically arranged based on the central axis, and the purpose is to simplify the calculation difficulty by directly substituting the spatial coordinates of the central axis into the calculation of the central position of each indenter 21 when calculating the spatial position of the indenter 21 by the inherent size of the mechanical structure in the crimping apparatus.

Of course, in other alternative embodiments, the plurality of gaps 2211 may also be arranged at equal intervals with a preset interval to form a plurality of combinations of the connecting portions 221, so that the adaptable size of the pressing head 21 is wider.

It can be understood that, when the press-connection block 213 is abutted against the display panel to form a predetermined displacement, the elastic element is not deformed to its maximum deformation state, and the elastic potential energy of the elastic element is the pressure applied by the press-connection block 213 to the display panel at this time.

Preferably, instead of using the pressure block 213 to form a value of the preset displacement back to the pressing direction to indirectly calculate the pressure value, a pressure sensor may be disposed between the elastic element and the carrier 212, and when the pressure block 213 presses the display panel, the pressure sensor may measure the pressure value of the pressure block 213 pressing the display panel in real time, so as to avoid poor pressing due to too low pressure or damage to the display panel due to too high pressure.
