[0002] With the deepening of life science research and the continuous development of clinical detection technology, biochips, as an advanced tool integrating microelectronics and biotechnology, have been widely used in many fields such as gene diagnosis, drug screening, disease prediction, etc. Biochips achieve miniaturization and great parallelization of gene detection by arranging a large number of different DNA probes on silicon wafers, significantly improving detection efficiency and accuracy.

[0003] However, biochips may be affected by a variety of factors during the production process, resulting in unstable performance or potential defects. In order to ensure the quality of biochips and improve their reliability and stability, strict testing after production is an essential step.

[0004] In the post-production testing of biochips, torque, pressure and airtightness tests are three crucial aspects. The torque test is mainly used to evaluate the stability and durability of the biochip when subjected to external torque, ensuring that it is not easily damaged during transportation, installation and use. The pressure test is used to simulate the working conditions of the biochip under extreme conditions to test its pressure resistance and structural stability. The airtightness test verifies whether the biochip packaging structure is tight to prevent data loss or damage due to air leakage.

[0005] However, there is no equipment on the market that can achieve this function, so we proposed an automatic chip detection device. Utility Model Content

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1 , 23. The utility model provides a technical solution: an automatic chip detection device, which consists of a bearing part 1, an airtightness test module 2, a driving module 3 and a digital microscope 4, wherein the airtightness test module 2, the driving module 3 and the digital microscope 4 are all installed on the surface of the bearing part 1, and the chip 5 to be tested is located in the test station of the airtightness test module 2. The driving module 3 can apply torque and pressure to the chip 5. When the driving module 3 applies torque and pressure to the chip 5, the airtightness test module 2 can detect the airtightness of the chip 5, and when the chip 5 is subjected to torque and pressure, the digital microscope 4 can observe the changes of the chip 5 during the chip 5 testing process.

[0031] See also Figure 4 The bearing part 1 includes a base 11, a bracket 12 is installed on the upper part of the base 11, a linear guide rail 13 is symmetrically installed on the front of the bracket 12, a through hole 14 and a through hole 2 15 are reserved, and a plurality of control buttons 16 are installed on the front of the base 11.

[0032] See also Figure 5 , 6 The air tightness test module 2 includes a frame 21 installed on the upper part of the load-bearing part 1 and a cylinder 28 installed on the back of the load-bearing part 1. A linear guide rail 22 is symmetrically installed on the upper part of the frame 21, and a fixture plate 23 is slidably connected to the upper part of the linear guide rail 22. A plurality of guide columns 24 are symmetrically connected to the upper part of the frame 21. A spring 25 is sleeved on the outside of each guide column 24. A lifting plate 26 is slidably connected to the outside of the plurality of guide columns 24. The spring 25 abuts between the frame 21 and the lifting plate 26. A plurality of air nozzles 27 are installed inside the lifting plate 26. The telescopic end of the cylinder 28 is connected to a pressing plate 210 through a linkage frame 29. The pressing plate 210 is slidably connected to the load-bearing part 1 through a linear guide rail 13, and the pressing plate 210 is located above the lifting plate 26.

[0033] When the air tightness test module 2 is working, the chip 5 to be tested is first fixed on the fixture plate 23, and then the fixture plate 23 is pushed inward into place. After it is in place, the chip 5 to be tested is just below a number of air nozzles 27. After being shortened by the cylinder 28, the pressure plate 210 is driven to move downward along the linear guide rail 13 through the linkage frame 29. The pressure plate 210 is pressed on the lifting plate 26 and continues to press down. During the downward movement of the lifting plate 26, it moves down along the guide column 24 and compresses the spring 25 until the bottom end of the air nozzle 27 contacts the surface of the chip 5. Then the air nozzle 27 generates pressure on the chip 5 to start the air tightness test.

[0034] See also Figure 7 , 8The driving module 3 includes a lifting frame 31 slidably connected to the front of the load-bearing part 1 through a linear guide rail 13, a pressure driving motor 36 installed on the back of the load-bearing part 1, a torque driving motor 32 is installed on the upper part of the lifting frame 31, and the driving end of the torque driving motor 32 is connected to a torque sensor 33 through a coupling, and the bottom end of the torque sensor 33 is connected to a pressure sensor 34 through a coupling, and the bottom end of the pressure sensor 34 is connected to a pressure rod 35, and the driving end of the pressure driving motor 36 is connected to a screw rod 37, and the external thread of the screw rod 37 is connected to a linkage frame 2 38, and the linkage frame 2 38 is connected to the lifting frame 31.

[0035] When the driving module 3 is working, the pressure driving motor 36 drives the screw rod 37 to rotate. Since the screw rod 37 and the linkage frame 2 38 are threadedly connected, when the screw rod 37 rotates, the linkage frame 2 38 will descend, thereby driving the lifting frame 31 to descend along the linear guide rail 13 until the pressure rod 35 is pressed on the chip 5 and applies pressure according to the set pressure. The pressure sensor 34 performs detection, and then the torque driving motor 32 indirectly drives the pressure rod 35 to rotate, forming a torque on the chip 5, which is detected by the torque sensor 33.

[0036] See also Fig. 9 A reserved hole 1 211 is provided on the upper portion of the frame 21 , and a reserved hole 231 is provided inside the fixture plate 23 . The digital microscope 4 can observe the changes of the chip 5 during the test process through the reserved hole 1 211 and the reserved hole 231 .

[0037] Finally, it should be noted that each air nozzle 27 is connected to an air pipe, and an air pressure sensor is installed on the air pipe. When detecting the air tightness, the air pressure sensor is used to detect whether there is leakage at the contact part between each air nozzle 27 and the chip 5. If there is leakage, it means that the air tightness of the chip 5 is unqualified. The air pressure sensor, torque sensor 33, pressure sensor 34 and digital microscope 4 can all communicate with the computer and can implement the transmission of air pressure, torque, pressure data and collected images to the computer. This technology is an existing well-known technology and will not be described in detail here.
