[0021] The main beneficial effects of this utility model are as follows:

[0022] 1. When using the auxiliary touchscreen and cover opening / closing device of this utility model, which enables automatic operation of a nucleic acid amplification instrument, the rear end of the second rotating rod is driven by the second rotation drive device to rotate in the left-right direction, causing the front end of the second rotating rod to rotate upwards and backwards. This, in turn, causes the upper cover connector to rotate upwards and backwards via the third and fourth rotating rods, ultimately causing the front handle of the PCR instrument's hot cover to rotate upwards and backwards. After the front handle rotates upwards and backwards at a certain angle, the rear end of the first rotating rod is driven by the first rotation drive device to rotate in the left-right direction, causing the front end of the first rotating rod to rotate upwards and backwards. This causes the second rotation drive device, the second rotating rod, the third rotating rod, the fourth rotating rod, and the upper cover connector to rotate upwards and backwards as a whole, opening the entire hot cover of the PCR instrument and completing the opening action. To close the cover, the operation process is the same as described above. Conversely, the process works as follows: A longitudinal and lateral movement drive mechanism moves the capacitive contact to the touch-sensitive position facing the touchscreen. Then, a contact extension mechanism extends the contact, causing it to move closer to the touch-sensitive position until it touches it. After the touch, the extension mechanism retracts the contact, moving it away from the touch-sensitive position, thus simulating a touchscreen action. After the touchscreen action, a camera captures the information displayed on the touchscreen, determining whether the touchscreen operation was correctly completed. Therefore, it is compatible with existing nucleic acid amplification instruments, enabling automatic cover opening and closing and auxiliary touchscreen functionality. This allows for integration with fully automated biochemical experimental equipment, significantly reducing laboratory costs and facilitating the widespread use of fully automated biochemical experimental equipment, making it suitable for large-scale application.

[0023] 2. When using the auxiliary touchscreen and cover opening / closing device of this utility model, which enables automatic operation of a nucleic acid amplification instrument, the rear end of the second rotating rod is driven by the second rotation drive device to rotate left and right, causing the front end of the second rotating rod to rotate upwards and backwards. This, in turn, drives the upper cover connector to rotate upwards and backwards via the third and fourth rotating rods, ultimately causing the front handle of the PCR instrument's hot cover to rotate upwards and backwards. After the front handle rotates upwards and backwards at a certain angle, the rear end of the first rotating rod is driven by the first rotation drive device to rotate left and right, causing the front end of the first rotating rod to rotate upwards and backwards. This, in turn, causes the second rotation drive device, the second rotating rod, the third rotating rod, the fourth rotating rod, and the upper cover connector to rotate upwards and backwards as a whole, opening the entire hot cover of the PCR instrument and completing the operation. The process involves opening the cover; to close the cover, the process is reversed. The capacitive contact is moved to the touch-sensitive position facing the touchscreen via a longitudinal and lateral movement drive. Then, the contact extension mechanism extends the contact, moving it closer to the touch-sensitive position until it touches it. After the touch, the extension mechanism retracts the contact, moving it away from the touch-sensitive position, thus simulating a touchscreen action. After the touchscreen action, a camera captures the information displayed on the touchscreen. The system determines whether the touchscreen operation was completed correctly based on this information. Therefore, its design is ingenious, its structure is simple, its manufacturing is easy, and its cost is low, making it suitable for large-scale application.

[0056] The camera mounting plate 45 is connected to the camera mounting plate 44 and its rotation angle relative to the camera mounting plate 44 in the left-right direction is adjustable.

[0058] In use, place the PCR instrument 5 in a suitable position on the base plate 1, place the touch screen mounting bracket 21 in front right of the PCR instrument 55 and set it on the base plate 1 (e.g., fixed with bolts), so that the vertically movable base plate 22 is parallel to the panel 51 of the PCR instrument 5 and located above the right side of the touch screen 52 of the panel 51, with the capacitive contact 29 facing the touch screen 52; place the switch cover mounting bracket 31 behind the right of the PCR instrument 5 and set it on the base plate 1 (e.g., fixed with bolts), and install the upper cover connector 38 on the front handle 54 of the hot cover 53 of the PCR instrument 5 (e.g., fixed with screws); place the lower end of the camera vertical support 42 to the right of the touch screen mounting bracket 21 and set it on the base plate 1 (e.g., fixed with bolts), and adjust the rotation angle of the camera mounting plate 45 relative to the camera mounting plate 44 in the left and right directions so that the camera 41 faces the touch screen 52.

[0059] During operation, the second rotation drive device 33 drives the rear end of the second rotating rod 35 to rotate left and right, causing the front end of the second rotating rod 35 to rotate upward and backward. This, in turn, drives the third rotating rod 36 and the fourth rotating rod 37 to rotate the top cover connector 38 upward and backward, ultimately causing the front handle 54 of the hot cover 53 of the PCR instrument 5 to rotate upward and backward. After the front handle 54 has rotated upward and backward to a certain angle, the first rotation drive device 32 drives the rear end of the first rotating rod 34 to rotate left and right, causing the front end of the first rotating rod 34 to rotate upward and backward. This, in turn, causes the second rotation drive device 33, the second rotating rod 35, the third rotating rod 36, the fourth rotating rod 37, and the top cover connector 38 to rotate upward and backward as a whole, opening the hot cover 53 of the PCR instrument 5 and completing the entire opening action.

This opening and closing action is applicable to a class of nucleic acid amplification instruments, represented by the Veriti amplification instrument from AB Corporation.

[0060] The longitudinal movement drive device 25 can drive the longitudinal movement slide 24 to move along the inclined direction of the longitudinal movement guide 23, thereby driving the lateral movement plate 26 and the contact extension device 28 to move along the inclined direction of the longitudinal movement guide 23, thereby driving the capacitor contact 29 to move along the inclined direction of the longitudinal movement guide 23; the lateral movement drive device 27 can drive the lateral movement plate 26 to move left and right, thereby driving the contact extension device 28 to move left and right, thereby driving the capacitor contact 29 to move left and right; thus, through the longitudinal movement drive device 25 and the lateral movement drive device 27, the capacitor contact 29 can be moved to any touch position facing the touch screen 52, and then the contact extension device 28 extends, causing the capacitor contact 29 to move towards the touch position until it touches the touch position. After touching, the contact extension device 28 shortens, causing the capacitor contact 29 to move away from the touch position, thereby performing a simulated touch screen action;

[0061] After a touch screen action is performed, the camera 41 captures the information displayed on the touch screen 52. Based on the information displayed on the touch screen 52, it is determined whether the touch screen operation was completed correctly. If it was not completed correctly, the above process can be repeated.

[0062] This invention can be integrated into a fully automated biochemical experimental device. The device issues relevant control commands; for example, upon issuing a command to open / close the heated cover 53, the second rotation drive device 33 and the first rotation drive device 32 are activated sequentially. First, the front handle 54 of the heated cover 53 moves, then the entire heated cover 53 moves, completing the opening action. The reverse process closes the heated cover 53. When a touchscreen operation command is issued, the vertical movement drive device 25 and the horizontal movement drive device 27 are activated, moving the capacitive contact 29 above the touch position on the touchscreen 52. Then, the contact extension device 28 extends, causing the capacitive contact 29 to move vertically downwards relative to the touch position, completing the touchscreen operation. After the touchscreen operation is completed, the camera 41 captures the information displayed on the touchscreen 52. Based on the information displayed on the touchscreen 52, it is determined whether the touchscreen operation was completed correctly, and other touchscreen operations can be performed according to subsequent commands. In this way, the operation of the PCR instrument 5 can be automatically completed under the control of the fully automated biochemical experimental device, achieving fully automated adaptation.

[0063] Therefore, this utility model provides an auxiliary touch screen and cover opening / closing device that enables automatic operation of a nucleic acid amplification instrument. The PCR instrument's hot cover can be opened and closed via the hot cover opening / closing mechanism, and the auxiliary touch screen mechanism enables touch screen operation on the PCR instrument's panel. The camera recognition mechanism can determine whether the touch screen operation has been completed correctly. This allows the existing manually operated PCR instrument to be used in conjunction with fully automated biochemical experimental equipment, thereby greatly saving laboratory costs and promoting the widespread use of fully automated biochemical experimental equipment.

[0064] In summary, the auxiliary touch screen and cover opening / closing device of this utility model, which enables automatic operation of nucleic acid amplification instruments, is compatible with existing nucleic acid amplification instruments, realizing automatic opening and closing of the cover and auxiliary touch screen, so as to be used in conjunction with fully automated biochemical experimental equipment, thereby greatly saving laboratory costs and facilitating the promotion and use of fully automated biochemical experimental equipment.
