[0044] Reference Figure 1 The present application discloses a DNA biosynthesis system, including two sets of visual systems, two sets of light source assemblies 20 and dual-camera position adjustment devices; the two sets of light source assemblies 20 are respectively matched with the two sets of visual systems; wherein the dual-camera position adjustment device includes two sets of adjustment devices, and the support plates 100 in the two sets of adjustment devices are the same plate; the field of view centers of the cameras 10 fixed by the two sets of adjustment devices coincide with the centers of the two cross marks in the chip to be detected.

Through the adjustment device disclosed in the application, the center of the field of view of the two cameras 10 can be basically completely overlapped with the center of the cross mark.

[0046] Reference Figure 1 and Figure 2 The adjusting device includes a support plate 100, a Z-axis translation stage 200, a turntable 300, a support rod 500, an adapter plate 400, a bearing plate 600 for mounting the camera 10, and a joint bearing unit 700. The Z-axis translation stage 200 is installed on the side of the support plate 100, and the turntable 300 is installed on the side of the Z-axis translation stage 200 away from the support plate 100, that is, one side of the Z-axis translation stage 200 is fixedly connected to the support plate 100, and the other side (that is, the outer side) has the degree of freedom of lifting and lowering along the Z direction (that is, it has the degree of freedom of movement parallel to the Z-axis direction), which can drive the lifting and lowering of the turntable 300 fixed on the outer side.

[0047] An adapter plate 400 is installed on the side of the turntable 300 away from the Z-axis translation stage 200. The adapter plate 400 is fixedly connected to the side of the turntable 300 through a plurality of support rods 500, and a storage space is formed between the adapter plate 400 and the turntable 300. The outer side surface of the turntable 300 has the freedom to rotate around the X-axis, and the support rods 500 can drive the adapter plate 400 to rotate around the X-axis.

[0048] The Z-axis translation stage 200 includes a first plate 210 fixed to the side of the support plate 100, a first guide rail fixedly mounted on the first plate 210, a second plate 220 (i.e., a slidable plate), a second guide rail fixedly mounted on the second plate 220, an adjusting knob 230, and a locking member 240.

The movement of the second plate 220 can be achieved by controlling the adjusting knob 230 (i.e., a fine-tuning knob), and the locking is performed by the locking member 240 (i.e., a locking screw). The adjusting knob 230 and the second plate 220 are separate structures, and force can only be applied in one direction. When rotating, the second plate 220 is reset by a spring.

[0049] Furthermore, the flatness of the second plate 220 is preferably about 5 micrometers.

[0050] The turntable 300 is a L / R manual rotating slide, which can realize 360-degree coarse adjustment and ±5-degree fine adjustment. Specifically, the turntable has a precision copper sleeve bearing inside, and the turntable can rotate 360 ​​degrees after the coarse adjustment is loosened. After the coarse adjustment, the fine adjustment knob can be used for fine adjustment (±5°), and after the fine adjustment, it is fixed by opposite locking.

[0051] The side of the manual rotating slide away from the second plate 220 is parallel to the Z direction and has rotational freedom. Specifically, the side of the manual rotating slide away from the second plate 220 has rotational freedom around a direction perpendicular to the second plate 220 (ie around the X axis).

[0052] The plurality of supporting rods 500 are all arranged in parallel and perpendicular to the side of the turntable 300 away from the Z-axis translation stage 200 , so as to ensure that the plane of the adapter plate 400 is parallel to the outer side of the turntable 300 .

[0053] Furthermore, at least four supporting rods 500 are provided to ensure the installation stability of the adapter plate 400 and the outer side surface of the turntable 300 .

[0054] When four support rods 500 are provided, the plurality of support rods 500 include a first rod 510, a second rod 520, a third rod 530 and a fourth rod 540, and a center line connecting the first rod 510 and the second rod 520 coincides with a diameter of the turntable 300; the third rod 530 and the fourth rod 540 are provided corresponding to the first rod 510 and the second rod 520 respectively.

[0055] In this embodiment, the adapter plate 400 is provided with a plurality of long slots matching the plurality of support rods 500; the longitudinal axis of the long slots is parallel to the first horizontal direction (eg, the Y axis), and the support rods 500 have the freedom to move along the longitudinal axis of the long slots;

[0056] The longitudinal axis of the support rod 500 is parallel to the second horizontal direction (eg, the X-axis), and the second horizontal direction is perpendicular to the first horizontal direction.

[0057] Since the support rod 500 is fixedly connected to the outer side of the turntable 300, the adapter plate 400 can freely move in the Y direction relative to the turntable 300 through a plurality of long slots, that is, it has a degree of freedom of movement parallel to the Y-axis direction.

[0058] A carrying plate 600 is arranged in the accommodating space (that is, the carrying plate 600 is arranged between the adapter plate 400 and the turntable 300), and a camera mounting portion is provided on the carrying plate 600. In this embodiment, the camera mounting portion includes a first mounting portion and a second mounting portion. The first mounting portion is provided with a body mounting plate 610 fixed to the body of the camera 10; the second mounting portion is provided with a lens limiting plate 620 fixed to the lens of the camera 10, so as to realize the position constraint of the lens so as to stably install the camera 10, that is, the camera 10 and the carrying plate 600 constitute a whole and move synchronously.

[0059] A plurality of joint bearing units 700 are mounted on the bearing plate 600 ; a plurality of adjustment holes are opened on the adapter plate 400 , and the free ends of the plurality of joint bearing units 700 are respectively connected to the plurality of adjustment holes, and each joint bearing unit 700 has the freedom of movement relative to the adapter plate 400 .

[0060] Specifically, the joint bearing unit 700 includes a bearing seat fixedly connected to the bearing plate 600, a joint bearing installed on the bearing seat, a locking cover installed on one side of the joint bearing, and an adjusting screw installed on the other side of the joint bearing. The free end of the adjusting screw is connected to the adapter plate 400 through a locking member 240; the locking member 240 includes a first nut and a second nut respectively arranged on both sides of the adapter plate 400, and the first nut and the second nut are both threadedly connected to the adjusting screw.

[0061] In this embodiment, three spherical bearing units 700 are preferably provided, and the centers of the three spherical bearing units 700 form a right triangle.

[0062] Also refer to Figure 3 The three joint bearing units 700 are respectively the first unit 710, the second unit 720, and the third unit 730; the center line of the first unit 710 and the second unit 720 is parallel to the center line of the first rod 510 and the second rod 520; the distance between the center of the first unit 710 and the center of the second unit 720 is h, and the distance between the center of the first rod 510 and the center of the second rod 520 is H, H / 2≤h<H, ensuring the load-bearing stability of the load-bearing plate 600 through the adapter plate 400.

[0063] Based on the principle that three points determine a plane, by separately adjusting the length of the adjusting screw in the first unit 710, the rotation adjustment of the supporting plate 600 around the Z axis can be achieved; by separately adjusting the length of the adjusting screw in the third unit 730, the rotation adjustment of the supporting plate 600 around the Y axis can be achieved; by simultaneously adjusting the lengths of the adjusting screws in the first unit 710, the second unit 720, and the third unit 730, the movement adjustment of the supporting plate 600 along a direction parallel to the X axis can be achieved.

[0064] The adjustment device disclosed in the present application can lift and lower the outer side surface of the Z-axis displacement stage 200 through the support rod 500, the adapter plate 400, the joint bearing unit 700, and the bearing plate 600, so that the camera 10 can be lifted and lowered along the Z-axis, that is, the position of the camera 10 in the Z-axis can be adjusted. The Z-axis displacement is to adjust the distance between the camera 10 lens and the chip surface to adjust the focal length; the outer side surface of the turntable 300 has the degree of freedom to rotate around the X-axis, and the adapter plate 400 can be driven to rotate around the X-axis through the support rod 500, that is, the camera 10 can be driven to rotate and adjust around the X-axis; a plurality of support rods 500 and 600 can be used to drive the adapter plate 400 to rotate around the X-axis. The connection between the rod 500 and the adapter plate 400 has a degree of freedom of movement parallel to the Y-axis direction, that is, it can drive the camera 10 to perform free movement adjustment parallel to the Y-axis direction; a number of joint bearing units 700 can realize the rotation adjustment of the carrier plate 600 around the Z-axis, the rotation adjustment around the Y-axis, and the movement adjustment along the direction parallel to the X-axis, that is, the rotation adjustment of the camera 10 around the Z-axis, the rotation adjustment around the Y-axis, and the movement adjustment along the direction parallel to the X-axis; through the adjustment device disclosed in the present application, the position adjustment of the six degrees of freedom of the loaded camera 10 can be realized.

[0065] In this embodiment, each set of visual system is installed to match the camera mounting part; the two sets of visual systems and the two sets of light source assemblies 20 are fixedly installed on the supporting plate 600, the support plates 100 in the two sets of adjustment devices are the same plate, the two sets of adjustment devices are installed at the same height, and the two sets of light source assemblies 20 are respectively installed on the two supporting plates 600.

[0066] Furthermore, the center position between the two sets of adjustment devices is set to coincide with the center of the support plate 100 to ensure installation stability.

[0067] Since the relative position of the camera 10 to the printing system and the chip is imprecise and cannot be determined when it is installed, the chip position can be fixed first, and the positions of the two cameras 10 can be adjusted based on the chip to achieve precise adjustment of the relative position of the visual system and the chip, thereby ensuring higher alignment accuracy.

[0068] Based on the above application scenarios and requirements, in the dual-camera position adjustment device, each camera can independently adjust the position with 6 degrees of freedom, including displacement in the X direction, displacement in the Y direction, displacement in the Z direction, rotation around the X axis, rotation around the Y axis, and rotation around the Z axis; the size and position accuracy of the two Marks on the chip are at the micron level, which is very accurate, so the relative position of the two cameras 10 can be judged and adjusted by the position of the Mark in the field of view of each camera 10. By precisely adjusting the spatial position of the two cameras 10 and locking them, high-precision visual alignment and high stability can be achieved, effectively reducing printing deviations and improving synthesis efficiency.

[0069] The adjustment device disclosed in the present application has several significant advantages in the field of DNA biosynthesis of high-throughput synthesis chips, including: providing multiple degrees of freedom adjustment capabilities through the combination of a Z-axis translation stage, a turntable and a support rod, ensuring that the camera can be precisely adjusted in the X, Y, and Z axis directions and in the rotation directions around the X, Y, and Z axes, which enables the camera to be accurately aligned with the cross mark on the chip, thereby improving the accuracy of printing; the relative position of the printing system and the chip is calculated through a visual system, and then the printing position is calibrated. The multi-degree-of-freedom adjustment can ensure that the camera can capture the image of the reaction site from the best viewing angle, thereby improving the accuracy of the calibration.

[0070] In this application, the carrier plate is connected to the adapter plate through a joint bearing unit, and can rotate around the Z axis and Y axis, and move along the X axis, so that the camera can be flexibly adjusted according to the design of different chips and the layout of reaction sites, and adapt to reaction sites of different sizes and spacings; the accommodation space formed between the adapter plate and the turntable allows the carrier plate and the camera to be placed in a relatively fixed environment, reducing the impact of the external environment and improving stability and reliability; the multi-degree-of-freedom adjustment capability allows the camera to quickly align with the cross mark on the chip, reducing calibration time and steps and improving work efficiency; high-precision positioning and calibration reduce synthesis failures or inefficient synthesis due to position errors and improve the efficiency of the overall synthesis process.

[0071] This device is particularly suitable for high-throughput synthesis chips. The required precise position can be achieved by simply adjusting the center of the camera's field of view to align with the cross mark on the chip, because the cross mark and the reaction site on the chip have absolute physical positions when the chip is processed. After the camera is aligned with the cross mark to determine the position of the cross mark, the position of the reaction site can be obtained through the algorithm. Therefore, it can ensure that each reaction site can be accurately printed at the same time to meet the needs of large-scale production. The design of the device allows adjustment according to different chip sizes and site layouts, has good scalability, and can adapt to production needs of different scales and types; multi-degree-of-freedom adjustment and high-precision positioning enable the device to remain stable during long-term use, reducing maintenance costs caused by error accumulation, and the design of the joint bearing unit and the support rod allows the device to be easily disassembled and maintained, reducing the cost of repair and replacement of parts.

[0072] In summary, the regulating device disclosed in the present application significantly improves the accuracy, efficiency and adaptability of the DNA biosynthesis process through multi-degree-of-freedom adjustment and high-precision positioning, is particularly suitable for the production of high-throughput synthesis chips, and has important practical application value.

[0073] Another aspect of the present application discloses a dual-camera position adjustment method, based on the biosynthesis system, comprising:

[0074] S100, respectively obtaining the positions of the centers of two cross marks in the chip to be inspected through two sets of visual systems;

[0075] S200, determining, according to the positions of the centers of the two cross marks, the distance between the centers of the two cross marks, a first deviation between the visual center of the first visual system and the center of the first cross mark, and a second deviation between the visual center of the second visual system and the center of the second cross mark;

[0076] The first deviation includes a first X-axis offset value, a first Y-axis offset value, and a first angle offset value; the second deviation includes a second X-axis offset value, a second Y-axis offset value, and a second angle offset value.

[0077] Among them, the first X-axis offset value represents the offset of the visual center of the first visual system relative to the center of the first cross mark in the X-axis direction; the first Y-axis offset value represents the offset of the visual center of the first visual system relative to the center of the first cross mark in the Y-axis direction; the first angle offset value represents the offset of the visual center of the first visual system relative to the center of the first cross mark in the angle direction (that is, whether the camera needs to be rotated to align with the center of the cross mark).

[0078] The second X-axis offset value represents the offset of the visual center of the second visual system relative to the center of the second cross mark in the X-axis direction; the second Y-axis offset value represents the offset of the visual center of the second visual system relative to the center of the second cross mark in the Y-axis direction; the second angular offset value represents the offset of the visual center of the second visual system relative to the center of the second cross mark in the angular direction.

[0079] S300, based on the first deviation amount and the second deviation amount, respectively adjust the positions of the corresponding visual systems through the dual-camera position adjustment devices until the centers of the fields of view of the cameras fixed by the two adjustment devices respectively coincide with the centers of the two cross marks in the chip to be inspected.

[0080] Based on the first deviation and the second deviation obtained by the above calculation, the system adjusts the positions of the two cameras respectively through the dual-camera position adjustment device.

[0081] Adjustment of the first camera: according to the first X-axis offset value, the adjusting device moves the first camera in the X-axis direction so that the visual center is aligned with the X coordinate of the center of the first cross mark; according to the first Y-axis offset value, the adjusting device moves the first camera in the Y-axis direction so that the visual center is aligned with the Y coordinate of the center of the first cross mark; according to the first angle offset value, the adjusting device rotates the first camera so that the angle of the visual center is aligned with the angle of the center of the first cross mark.

[0082] Adjustment of the second camera: According to the second X-axis offset value, the adjusting device moves the second camera in the X-axis direction so that its visual center is aligned with the X coordinate of the center of the second cross mark; according to the second Y-axis offset value, the adjusting device moves the second camera in the Y-axis direction so that its visual center is aligned with the Y coordinate of the center of the second cross mark; according to the second angle offset value, the adjusting device rotates the second camera so that the angle of its visual center is aligned with the angle of the center of the second cross mark.

[0083] The process is iterative, and the system will continuously detect whether the visual centers of the two cameras completely overlap with the centers of the cross marks. If there is still a deviation, the system will continue to adjust until the centers of the field of view of the two camera systems are completely aligned with the centers of the two cross marks.

[0084] When the visual centers of the two cameras completely coincide with the centers of the two cross marks, the adjustment process is completed and the system enters the normal working state, ready for subsequent detection or measurement tasks.

[0085] Through the above steps, the dual-camera position adjustment method can accurately adjust the positions of the two camera systems to ensure that they can accurately align with the centers of the two cross marks in the chip to be inspected, thereby improving the accuracy and stability of the inspection.
