[0073] The working principle of this utility model:

[0074] 1. The substrate 12 is located at a designated position. A plurality of pins 121 are disposed on the substrate 12 . The plurality of pins 121 are not arranged symmetrically.

[0075] 2. The detection device 24 takes a photo of the cover plate 11 to be grasped for detection. The detection device 24 is used to identify whether the cover plate 11 to be grasped corresponds to the substrate 12.

[0076] In this embodiment, there are pinholes on the cover plate 11, and the pinholes correspond to the pins 121 on the substrate 12; the pinholes are not arranged symmetrically, and according to the pins 121 on the substrate 12, the detection device 24 identifies whether the cover plate 11 to be grasped corresponds to the substrate 12.

[0077] 3. Grab the cover plate 11.

[0078] (1) The cover plate 11 is accurately moved in the X-axis and Y-axis directions by precise control of the first guide rail group 25 and the second guide rail group 26 until the clamping jaws 22 are located above the cover plate 11 .

[0079] (2) Start the driving member 224 to open the first clamping member 222 and the second clamping member 223 to their maximum at the same time; the lifting device 23 drives the clamping claw 22 to move above the cover plate 11, and then the driving member 224 drives the clamping member to close and accurately clamp the cover plate 11. After the first sensor 27 detects that the clamping claw 22 grabs the cover plate 11, proceed to the next step. The detection device 24 automatically captures and identifies the position of the cover plate 11, and the light source assembly 243 provides sufficient lighting to ensure that the operation process is clearly visible.

[0080] The first clamping member 222 and the second clamping member 223 are driven to open and close by the driving member 224 to clamp the front and back and left and right sides of the cover plate 11 to achieve stable fixation.

[0081] 4. Pre-press the cover plate 11.

[0082] (1) The clamping jaws 22 are controlled to be located above the substrate 12 by the first guide rail set 25 and the second guide rail set 26 .

[0083] (2) According to the recognition result of the detection device 24, the rotating device 29 adjusts the direction of the cover plate 11, and the rotating device 29 drives the clamping jaws 22 and the cover plate 11 to rotate to the required angle to achieve the complex docking requirements. Until the second sensor 28 detects that the cover plate 11 is flipped into place, the cover plate 11 corresponds to the substrate 12, ensuring that the pinhole and the pin 121 are accurately aligned.

[0084] (3) The lifting device 23 controls the downward movement of the clamping jaw 22, and the clamping jaw 22 is pressed downward as a whole. The top surface of the cover plate 11 abuts against the pressure block 2234, so that the pressure block 2234 moves upward. The pressure block 2234 abuts against the connecting plate 225. The third sensor 226 detects the pre-pressure applied by the mounting plate 221 to avoid damaging the clamping jaw, thereby achieving stable pre-pressure of the cover plate 11.

[0085] This completes the working process of the cover plate pre-pressing mechanism of this preferred embodiment.

[0086] The lifting device, the first guide rail group and the second guide rail group in the present application can adopt a variety of existing mature technologies to realize the precise driving movement and operation of the cover plate pre-pressing device, including but not limited to screw drive, cylinder drive or electric motor drive, etc. The specific selection of the driving method will not be elaborated here.

[0087] The first sensor and the second sensor are indispensable components of the automatic control system. Since these sensor technologies are already quite mature and popular, their working principles, types (such as photoelectric sensors, proximity sensors, pressure sensors, etc.) and extensive application cases in the modern industrial field, this application will not elaborate on the specific technical details of the first sensor and the second sensor.
