[0037] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0038] As Figure 1 shown, a preferred embodiment of the utility model provides an automatic scanning DNA visual extraction robot system, which mainly comprises a machine table 1, a multi-axis robot 3, a biological evidence discovery device 4, a detection platform 2 and the like, wherein the multi-axis robot 3 is installed on the machine table 1, the biological evidence discovery device 4 is fixedly installed on the multi-axis robot 3, and the multi-axis robot 3 has multiple moving axes and can accurately control the movement of the biological evidence discovery device 4. The detection platform 2 is located on one side of the machine table 1, and the detection platform 2 has a detection area 201 for placing an object to be detected on the detection platform 2, and the detection area 201 is a plane. After the object to be detected is placed on the detection area 201, the multi-axis robot 3 will automatically control the biological evidence discovery device 4 to move above the object to be detected, and the biological evidence discovery device 4 will automatically find biological traces on the object to be detected.

[0039] As Figures 2-7 shown, the biological evidence discovery device 4 mainly comprises a shell 41, a display screen 42, a camera 48, an objective lens 6, a master control panel 410, a lamp bead control circuit board 418, a power board 411, a motor 415, a skeleton 412, a mounting back plate 413, a filter 417 and a filter mounting bracket 416 and the like, wherein the shell 41 has a cavity inside, and the camera 48, the master control panel 410, the lamp bead control circuit board 418, the power board 411, the motor 415, the skeleton 412, the mounting back plate 413, the filter 417 and the filter mounting bracket 416 and the like are installed in the cavity.

[0040] The skeleton 412 is provided with two skeletons, which are symmetrically installed on the two sides of the inner side of the shell 41, the mounting back plate 413 is installed on the back of the inner side of the shell 41, the two ends of the mounting back plate 413 are fixedly connected with the two skeletons 412 through screws, the lamp bead fixing plate 45 is installed at the bottom of the shell 41, and the lower sides of the skeleton 412 and the mounting back plate 413 are fixedly connected with the lamp bead fixing plate 45 through screws, so that the mounting back plate 413 and the two skeletons 412 jointly form a stable frame structure, which can play a supporting role and simultaneously strengthen the structural strength of the shell 41.

[0041] Reference Figure 6The mounting plate 49 is located between the two skeletons 412, and the two ends of the mounting plate 49 are fixedly connected with the two skeletons 412 respectively by screws. The motor 415 is provided with two, and the two motors 415 are vertically fixed at positions close to the two ends of the mounting plate 49.

[0042] Referring to Figure 10 The filter mounting bracket 416 is circular in shape, and there are two of them. The two filter mounting brackets 416 are distributed in parallel from top to bottom, and are fixedly connected with the output ends of the two motors 415 respectively, and the two motors 415 control the rotation of the two filter mounting brackets 416 respectively.

[0043] A plurality of circular holes are formed in the circumferential direction of the filter mounting bracket 416, and each circular hole is provided with a filter 417. The specifications of the filters 417 in different circular holes are different. The two filter mounting brackets 416 overlap in a part of the region. The projection of one filter 417 of one filter mounting bracket 416 in the overlapping region overlaps with the projection of one filter 417 of the other filter mounting bracket 416 from top to bottom, so that the lens of the camera 48 can penetrate through the two superimposed filters 417 to shoot the biological evidence below.

[0044] The filter 417 can protect the lens of the camera 48, eliminate or weaken the reflection of light, improve the picture effect, adjust the color temperature, achieve special effects, and change the image tone. The two motors 415 control the rotation of the two filter mounting brackets 416 respectively, and switch different filters 417. When the filters 417 on the two filter mounting brackets 416 are used in combination, dozens of different combination schemes can be extended for selection.

[0045] The camera 48 is vertically fixed on the mounting plate 49, and the camera 48 is located directly above the two overlapping filters 417. The lens of the camera 48 faces downward, and the lens of the camera 48 can penetrate through the two overlapping filters 417 to shoot the biological evidence below.

[0046] Referring to Figure 4 , Figures 9-11 The middle of the lamp bead fixing plate 45 has a rectangular hole, so that the camera 48 can shoot the biological evidence below through the rectangular hole. The bottom surface of the lamp bead fixing plate 45 has five surfaces, and the five surfaces are spliced to form a prismatic conical surface. The upper part of the lamp bead fixing plate 45 is also prismatic, and it also has five surfaces, each of which has a plurality of holes, each of which corresponds to a lamp bead 46 on the lamp bead control circuit board 418, so that the light emitted by the lamp bead 46 can pass through the hole to illuminate the evidence placed in the detection area 201 below, and the biological evidence on the evidence is displayed.

[0047] The lamp bead control circuit board 418 includes a first lamp bead control circuit board 4181, a second lamp bead control circuit board 4182, and a third lamp bead control circuit board 4183. The second lamp bead control circuit board 4182 and the third lamp bead control circuit board 4183 each have two pieces, and the two pieces of the second lamp bead control circuit board 4182 are respectively mounted and fixed on the left and right two surfaces of the upper part of the lamp bead fixing plate 45, and the third lamp bead control circuit board 4183 is respectively mounted and fixed on the front and rear two surfaces of the upper part of the lamp bead fixing plate 45. The first lamp bead control circuit board 4181 is mounted and fixed on the middle plane of the lamp bead fixing plate 45. At the same time, the middle of the first lamp bead fixing plate 45 also has a rectangular hole to prevent blocking the field of view of the camera 48.

[0048] A plurality of lamp beads 46 are arranged on each lamp bead control circuit board 418, and the wavelengths of the light emitted by each lamp bead 46 are different, and the colors of the light are also different due to the different wavelengths, so that when the biological samples on the evidence produce a fluorescent reaction, the colors of the biological samples on the evidence will also be different.

[0049] The size of the above-mentioned detection area 201 is the size of the field of view of the camera 48.

[0050] Reference Figure 4 、 Figure 11 Among them, a plurality of lamp beads 46 on the first lamp bead control circuit board 4181 are uniformly distributed around the circumferential direction of the middle rectangular hole, and the lamp beads 46 with corresponding wavelengths are centrally symmetrically distributed along the center of the rectangular hole. The structure of the lamp beads 46 on the two second lamp bead control circuit boards 4182 is the same, but the two second lamp bead control circuit boards 4182 are also centrally symmetrically distributed along the center of the rectangular hole. At the same time, the structure of the lamp beads 46 on the two third lamp bead control circuit boards 4183 is the same, and the two third lamp bead control circuit boards 4183 are also centrally symmetrically distributed along the center of the rectangular hole.

[0051] Since the second lamp bead control circuit board 4182 and the third lamp bead control circuit board 4183 are installed on the inclined surface, and furthermore, the lamp beads 46 on the second lamp bead control circuit board 4182 and the third lamp bead control circuit board 4183 are centrally symmetrically distributed, the light emitted by the lamp beads 46 with corresponding wavelengths on each lamp bead control circuit board 418 can be converged in the lower detection area 201 and directly irradiate all corners of the evidence, so that the evidence is in a shadowless environment when biological trace samples are detected, which is beneficial to the discovery of trace samples.

[0052] As Figure 5As shown, the objective lens 6 is fixed on the bottom of the fixing member 7, and a circular mounting hole is formed in the middle of the fixing member 7 for mounting the objective lens 6. The objective lens 6 is fixed below the rectangular hole in the middle of the lamp bead fixing plate 45 through the fixing member 7, concentric with the camera 48 and located directly below the camera 48. The objective lens 6 is a high-power magnifying lens, and the magnification of the camera 48 itself and the magnification of the objective lens 6 are superimposed, so that the target can be magnified by tens or hundreds of times, and extremely fine biological evidence can be magnified.

[0053] Reference Figure 12 Two magnets 8 are arranged at the two ends of the upper part of the fixing member 7, and the fixing member 7 is adsorbed in the middle of the bottom of the lamp bead fixing plate 45 through the magnets 8, so that the objective lens 6 can be quickly mounted, and the installation and disassembly are convenient. In other technical solutions, the fixing member 7 can also be clamped with the bottom of the lamp bead fixing plate 45.

[0054] Two avoiding holes 701 are formed in the fixing member 7 near the two ends, and the positions of the avoiding holes 701 correspond to the positions of the lamp beads 46 on the first lamp bead control circuit board 4181, so that the light emitted by the lamp beads 46 can pass through the avoiding holes 701 and irradiate the evidence below.

[0055] As shown in Figure 1 and Figure 5 When the objective lens 6 is not used, it is placed on the machine table 1, and when it is used, it only needs to be adsorbed and fixed on the bottom of the lamp bead fixing plate 45, which is convenient and fast.

[0056] As shown in Figure 6 The total control board 410 and the power supply board 411 are both installed inside the shell 41, and the five lamp bead control circuit boards 418 are all electrically connected with the total control board 410. The total control board 410 is a total control circuit board, which can process and analyze data and control the work of other electronic components.

[0057] A protection plate 414 is also installed on the bottom of the mounting plate 49, which is located above the lamp bead control circuit board 418 and plays a protective role to protect the lamp bead control circuit board 418.

[0058] As shown in Figure 2 , Figure 6 The power supply board 411 and the display screen 42 are also electrically connected with the total control board 410, and the display screen 42 is installed on the front of the shell 41. The display screen 42 is a touch display screen 42, which can select and switch different filter 417 matching schemes and select the lamp beads 46 that can emit corresponding wavelength light through touch.

[0059] Reference Figure 3On the back of the outer shell 41, an interface assembly 43 is further arranged, which mainly comprises a power interface 431 and a USB interface 432. The power interface 431 is electrically connected with the power board 411, and the power interface 431 is externally connected with a power supply. The power board 411 automatically distributes the voltage to different electronic devices. The USB interface 432 is electrically connected with the general control board 410, and the USB interface 432 can be externally connected with a computer or other electronic products. The signal is transmitted to the computer through the USB interface 432, so that the window displayed on the display screen 42 can be projected on the computer.

[0060] As shown in Figure 4 , a distance measuring sensor 47 is arranged at each of the four corners of the bottom of the lamp bead fixing plate 45, which is electrically connected with the general control board 410. The distance measuring sensor 47 can detect the distance between the biological evidence and the object below in real time, so as to adjust the distance between the camera 48 and the object, so that the camera 48 can clearly shoot the object below.

[0061] Referring to Figure 3 , Figure 7 On the back of the outer shell 41, a bracket connecting plate 44 is further arranged, which is fixedly connected with the mounting back plate 413 inside the outer shell 41 through screws, and has a plurality of mounting holes on the bracket connecting plate 44. Screws are arranged in each mounting hole, and an assembly plate 5 is mounted on the multi-axis robot 3. The bracket connecting plate 44 is fixed on the assembly plate 5 through screws, so as to fix and mount the biological evidence discovery equipment 4 on the multi-axis robot 3, which is convenient for quick installation and disassembly.

[0062] As shown in Figure 2 , in order to facilitate holding, a handle 402 is mounted on each of the left and right sides of the outer shell 41. The handle 402 is fixed on the skeleton 412 through screws. A person can manually hold the handles 402 on both sides to carry the table type biological evidence discovery equipment 4.

[0063] A switch 401 is further arranged on the top of the outer shell 41, which is electrically connected with the general control board 410, and is used to turn on or off the table type biological evidence discovery equipment 4.

[0064] During operation, the object to be detected is placed on the detection platform 2 in the detection area 201. Then the multi-axis robot 3 controls the biological evidence discovery equipment 4 to move above the object to be detected. The distance measuring sensor 47 detects the distance between the biological evidence discovery equipment 4 and the object to be detected in real time. The multi-axis robot 3 adjusts the position of the biological evidence discovery equipment 4 in real time according to the measured distance information.

[0065] The artificial touch display screen 42 selects the corresponding filter 417 collocation scheme and selects the lamp bead 46 capable of emitting corresponding wavelength light, the corresponding wavelength light emitted by the lamp bead 46 directly irradiates all surfaces of the evidence, and the biological samples on the evidence are displayed by using the principle that the irradiation of specific wavelength spectrum can excite fluorescence reaction, then the camera 48 photographs the evidence below, and the image is uploaded to the display screen 42 to display, and the evidence can be directly observed on the display screen 42 to take evidence.

[0066] The biological sample finding device 4 can also automatically use all filter 417 collocation schemes and lamp bead 46 selection schemes together according to the degree of the system, and sequentially arrange and display the images collected by all schemes on the display screen 42, so that the staff can select the optimal image from the images, and facilitate the taking of biological samples in the later period.

[0067] The above technical scheme only embodies the preferred technical scheme of the technical scheme of the present application, and some changes made by the person skilled in the art to some parts also embody the principle of the present application and belong to the protection scope of the present application.
