[0031] When using the novel gene sequencing chip pressing platform of the present invention, the chip to be tested 3 is placed on the heating plate 2, and is roughly aligned with the positioning mechanism 7 to ensure initial alignment. The operator manually presses the cover plate 407. During the downward pressing process, the chip pressing platform performs the following three actions in sequence:

[0032] The first action: chip positioning, the paddle 408 is pressed down along with the cover plate 407, and contacts the upper surface 2 771 of the push rod 77. The push rod 77 rotates under the action of the compression spring 2 76, and at the same time drives the push claw 71 to be linked through the push claw telescopic shaft 72 and the limit plate 74, pushing the chip 3 to be tested diagonally into the positioning mechanism 7, completing the precise positioning of the chip. The second action: chip pressing, when the cover plate part 4 continues to press down, the pressure heads in the pressure head assembly 1 405, the pressure head assembly 2 406, the pressure head assembly 3 410 and the pressure head assembly 4 411 contact the chip 3 to be tested. Through the structure of the cover plate 407 and the buffering effect of the damper fixing seat 401 and the cylindrical damper 402, the chip 3 to be tested is evenly pressed onto the heating plate 2 to ensure that the chip will not shift or warp during the heating process. The third action, locking, involves further downward pressure on the cover 407, causing the latch 409 to engage the raised portion on the lever 83. Once the cover 407 is fully pressed into place, the latch 409 and the raised portion fully engage, completing the locking process. At this point, the chip under test 3 is securely fixed to the heating plate 2.

[0033] Unloading: The operator presses the button 84, which drives the pin 81 to move downward, compressing the compression spring 3 82, further pushing the lever 83 to rotate. The rotation of the lever 83 causes the raised portion on it to disengage from the buckle 409, and the locking state of the cover 407 is released. Under the tension of the tension spring 5, the cover 407 bounces upward to its initial position. When the cover 407 rises, the pressure heads in the pressure head assembly 1 405, the pressure head assembly 2 406, the pressure head assembly 3 410 and the pressure head assembly 4 411 gradually separate from the chip to be tested 3, ensuring that the chip is not affected by external forces. At the same time as the cover 407 bounces up, the push rod 77 resets and drives the push claw 71 to retract through the push claw telescopic shaft 72, completely separating from the chip to be tested 3. The operator removes the chip to be tested 3 from the heating plate 2, completing the entire operation process.
