[0024] refer to Figure 1 As shown, existing pipetting robots typically place multiple well plates 15 on their stage, with the well plates 15 evenly spaced. The gripper 16 identifies the position of each well plate 15 and then picks it up for transfer. To ensure the reliability of the gripper 16's gripping, the overall frame 1 of the pipetting robot must be stable and without tilting. If the overall frame 1 of the pipetting robot is tilted, it will affect the gripper 16 and the pipette teaching, preventing accurate gripping of each well plate 15 and leading to failed drug transfer.

[0025] Currently, the assembly of pipetting robots is done by assembly workers, which is not only inefficient, but also makes it impossible to ensure that the frame 1 structure is stable and tilt-free during the construction process.

[0026] To address the problems existing in the prior art, the embodiments of this application provide a tooling fixture for fixing and installing a pipetting robot frame 1, which improves the installation efficiency of the pipetting robot frame 1 and ensures the stability of the pipetting robot frame 1 structure.

[0027] Specifically, refer to Figures 1 to 3 As shown, frame 1 includes a base plate 11, a top plate 12, a first side plate 13, and a second side plate 14, with the first side plate 13 and the second side plate 14 arranged opposite to each other. The base plate 11 is located at the bottom of the first side plate 13 and the second side plate 14 and is connected to the first side plate 13 and the second side plate 14. The top plate 12 is located at the top of the first side plate 13 and the second side plate 14 and is connected to the first side plate 13 and the second side plate 14.

[0028] The tooling fixture includes a base 2, a sliding assembly 3, and a support assembly 4. The sliding assembly 3 includes a first sliding platform and a second sliding platform arranged opposite each other on the same horizontal plane. Both the first and second sliding platforms are slidably mounted on the base 2, thus the distance between them is adjustable. The support assembly 4 includes a first support plate 41 and a second support plate 42 arranged opposite each other. The first support plate 41 is vertically mounted on and fixedly connected to the first sliding platform. The first support plate 41 has a first positioning element 5 for positioning the first side plate 13. The second support plate 42 is vertically mounted on and connected to the second sliding platform. The second support plate 42 has a second positioning element 6, the positions of which correspond to those of the first positioning element 5. The second positioning element 6 is used to position the second side plate 14.

[0029] In this embodiment, when assembling the frame 1 of the pipetting robot using a tooling fixture, the positioning holes on the first side plate 13 are aligned with the first positioning member 5, and the first side plate 13 is moved so that the first positioning member 5 passes through the positioning holes on the first side plate 13, thus completing the positioning of the first side plate 13. Then, in the same manner, the second positioning member 6 is passed through the positioning holes on the second side plate 14, thus completing the positioning of the second side plate 14. Next, the distance between the first sliding platform and the second sliding platform is adjusted, and the bottom plate 11 and the top plate 12 are connected to the first side plate 13 and the second side plate 14, completing the assembly of the frame 1.

[0030] It is understandable that using the tooling fixtures provided in this embodiment to build the frame 1 not only improves the assembly efficiency, but also ensures the stability of the pipetting robot frame 1 structure and avoids the frame 1 tilting after assembly.

[0031] refer to Figure 3 and Figure 4As shown, in some embodiments, the first positioning member 5 has a first limiting part 51 and a first positioning part 52. The first limiting part 51 has a disc-shaped structure, and the first positioning part 52 has a cylindrical structure, so that the first positioning member 5 has a "T"-shaped structure. A first through hole adapted to the size of the first positioning part 52 is provided on the first support plate 41. One end of the first positioning part 52 can pass through the first through hole and is located between the first support plate 41 and the second support plate 42. The first limiting part 51 is located on the side away from the second support plate 42 and is connected to the first support plate 41. The second positioning member 6 has a second limiting part 61 and a second positioning part 62. The structure of the second positioning member 6 is the same as that of the first positioning member 5. A second through hole adapted to the size of the second positioning part 62 is provided on the second support plate 42 corresponding to the first through hole. One end of the second positioning part 62 can pass through the second through hole and is located between the first support plate 41 and the second support plate 42. The second limiting part 61 is located on the side away from the first support plate 41 and is connected to the second support plate 42.

[0032] In this embodiment, since the positions of the first through hole and the second through hole are corresponding, and the structures of the first positioning member 5 and the second positioning member 6 are the same, it can be ensured that the frame 1 will not tilt after installation by positioning the first side plate 13 with the first positioning member 5 and positioning the second side plate 14 with the second positioning member 6.

[0033] In some embodiments, the first limiting part 51 is detachably connected to the first support plate 41, and the second limiting part 61 is detachably connected to the second support plate 42.

[0034] In this embodiment, both the first limiting part 51 and the second limiting part 61 are provided with a plurality of mounting holes arranged in a ring. Both the first support plate 41 and the second support plate 42 are provided with threaded holes. In this embodiment, bolts are passed through the mounting holes and threaded holes to connect, thereby realizing the detachable connection between the first limiting part 51 and the first support plate 41, and the detachable connection between the second limiting part 61 and the second support plate 42.

[0035] refer to Figure 4 and Figure 5 As shown, in some embodiments, the tooling fixture further includes a calibration element 7 for calibrating the relative positions of the first positioning element 5 and the second positioning element 6. The calibration element 7 has a cylindrical structure, and its length is greater than the sum of the lengths of the first positioning element 5 and the second positioning element 6. The first positioning element 5 has a first channel 53 along its axial direction, which conducts through the first positioning element 5. The second positioning element 6 has a second channel 63 along its axial direction, which conducts through the second positioning element 6. Both the first channel 53 and the second channel 63 are adapted to the calibration element 7.

[0036] It should be noted that after prolonged use, the bolt structure that fixes the first positioning element 5 and the second positioning element 6 may deform. When the bolt structure deforms, the relative positions of the first positioning element 5 and the second positioning element 6 may shift.

[0037] Therefore, in this embodiment, a calibration component 7 is used to calibrate the tooling fixture. Specifically, during calibration, the first sliding platform and / or the second sliding platform are moved so that the first positioning component 5 and the second positioning component 6 approach each other until they contact. Then, the calibration component 7 passes through the first channel 53 and the second channel 63 to fix the first positioning component 5 and the second positioning component 6. It is understood that if the relative positions of the first positioning component 5 and the second positioning component 6 shift, and the calibration component 7 cannot pass through the first channel 53 and the second channel 63 simultaneously, the original bolts need to be removed, and the positions of the first positioning component 5 and the second positioning component 6 need to be adjusted until the calibration component 7 can pass through the first channel 53 and the second channel 63. Finally, new bolts are used to re-fix the first positioning component 5 and the second positioning component 6 to complete the calibration work, thereby improving the reliability of the tooling fixture.

[0038] refer to Figure 3 , Figure 4 and Figure 6 As shown, in some embodiments, the tooling fixture further includes a detection element 8, which has a detection channel 81 along its axial direction. The detection channel 81 is adapted to the first positioning part 52 of the first positioning element 5 and the second positioning part 62 of the second positioning element 6.

[0039] In this embodiment, in order to further ensure the reliability of the tooling fixture after calibration, the tooling fixture needs to be tested using the test piece 8 after the calibration is completed.

[0040] Specifically, when using the detection component 8 for testing, one end of the detection component 8 is fitted onto the first positioning part 52 through the detection channel. The first sliding platform and the second sliding platform are moved so that the second positioning part 62 and the other end of the detection component 8 are close together. If the second positioning part 62 can be inserted into the detection channel, it is determined that the positions of the first positioning component 5 and the second positioning component 6 are corresponding. This method is used to further test and verify the calibrated tooling fixture, thereby ensuring the reliability of the calibrated tooling fixture.

[0041] refer to Figure 3 and Figure 7As shown, in some embodiments, the sliding assembly 3 includes a first slide rail 31, a second slide rail 32, a first slider 33, a second slider 34, a first connecting plate 35, and a second connecting plate 36. The first slide rail 31 and the second slide rail 32 are spaced apart and parallel to each other on the base 2. Two first sliders 33 are spaced apart on the first slide rail 31, and two second sliders 34 are spaced apart on the second slide rail 32, with each first slider 33 corresponding to one second slider 34, forming a slider group. The first connecting plate 35 is connected to one slider group to form a first sliding platform, and the second connecting plate 36 is connected to another slider group to form a second sliding platform.

[0042] In this embodiment, the first slide rail 31 and the second slide rail 32, the first slider 33 and the second slider 34, and the first connecting plate 35 and the second connecting plate 36 have the same structure, so the height of the first sliding platform and the second sliding platform formed by installation is on the same horizontal plane.

[0043] refer to Figure 3 As shown, in some embodiments, the support assembly 4 further includes a first connecting rib 43 and a second connecting rib 44. The bottom end of the first support plate 41 is connected to the first connecting plate 35. The first connecting rib 43 is located on the side away from the second support plate 42 and is connected to both the first connecting plate 35 and the first support plate 41 to enhance the structural stability of the first support plate 41. The bottom end of the second support plate 42 is connected to the second connecting plate 36. The second connecting rib 44 is located on the side away from the first support plate 41 and is connected to both the second connecting plate 36 and the second support plate 42 to enhance the structural stability of the second support plate 42.

[0044] In this embodiment, the first connecting rib 43 is detachably connected to both the first connecting plate 35 and the first support plate 41, and the second connecting rib 44 is detachably connected to both the second connecting plate 36 and the second support plate 42.

[0045] In some embodiments, the first support plate 41 has a rectangular first connecting portion 411, which is located between the first support plate 41 and the second support plate 42 and is connected to the first support plate 41. The two ends of the first connecting portion 411 extend out of the two sides of the first support plate 41, and both ends of the first connecting portion 411 are provided with a first positioning member 5.

[0046] The second support plate 42 has a second connecting portion 421, which has the same structure and position as the first connecting portion 411. The second connecting portion 421 is located between the first support plate 411 and the second support plate 42, and is connected to the second support plate 42. Both ends of the second connecting portion 421 extend out from both sides of the second support plate 42, and both ends of the second connecting portion 421 are provided with second positioning members 6.

[0048] Furthermore, a first connecting hole is provided on the first connecting part 411, and a second connecting hole is provided on the second connecting part 421.

[0049] In this embodiment, after the first side plate 13 is positioned by the first positioning member 5, the first connecting part 411 can be fixed to the first side plate 13 by passing a fixing bolt through the first connecting hole. Similarly, after the second side plate 14 is positioned by the second positioning member 6, the second connecting part 421 can be fixed to the second side plate 14 by passing a fixing bolt through the second connecting hole. This method further ensures the stability of the frame 1 during installation.

[0050] In another embodiment of this utility model, a method for assembling a pipetting robot frame is provided, which uses the tooling fixtures provided in the above embodiments for installation, with reference to... Figure 8 and combined Figures 1 to 7 As shown, the installation method includes the following steps: S101: Align the positioning hole on the first side plate 13 with the first positioning member 5 to mount the first side plate 13 onto the first support plate 41.

[0051] Specifically, in this step, the positioning hole on the first side plate 13 corresponds to the first positioning member 5. The first side plate 13 is moved so that the first positioning part 52 on the first positioning member 5 passes through the positioning hole on the first side plate 13. Then, the first side plate 13 is fixedly connected to the first support plate 41 by fixing bolts.

[0052] S102: Align the positioning holes on the second side plate 14 with the second positioning member 6 to mount the second side plate 14 onto the second support plate 42.

[0053] Specifically, in this step, the positioning hole on the second side plate 14 corresponds to the second positioning member 6. The second side plate 14 is moved so that the second positioning part 62 on the second positioning member 6 passes through the positioning hole on the second side plate 14. Then, the second side plate 14 is fixedly connected to the second support plate 42 by fixing bolts.

[0054] S103: Move the first sliding platform and / or the second sliding platform to adjust the distance between the first side plate 13 and the second side plate 14.

[0055] In this step, the distance between the first sliding platform 13 and the second sliding platform is made equal to the distance between the bottom plate 11 and the top plate 12 by moving the first sliding platform and / or the second sliding platform.

[0056] S104: Place the bottom plate 11 and the top plate 12 between the first side plate 13 and the second side plate 14, and connect the bottom plate 11 and the top plate 12 to the first side plate 13 and the second side plate 14.

[0057] In this step, the base plate 11 is fixedly connected to the first side plate 13 and the second side plate 14 by bolts, and the top plate 12 is fixedly connected to the first side plate 13 and the second side plate 14 by bolts, thus completing the construction of the frame 1.

[0058] In this embodiment, by using tooling fixtures to assist in the installation of the frame 1 of the pipetting robot, the installation efficiency of the frame 1 is improved, and the stability of the frame 1 structure is ensured.

[0059] In another embodiment of this utility model, a calibration method for a tooling fixture is provided for calibrating the tooling fixture provided in the above embodiments, with reference to... Figure 9 and combined Figures 1 to 7 As shown, the calibration method includes: S201: Move the first sliding platform and / or the second sliding platform to make the first positioning member 5 and the second positioning member 6 contact each other.

[0060] In this step, the first sliding platform and / or the second sliding platform are moved so that the first positioning member 5 and the second positioning member 6 are brought closer to each other until the first positioning member 5 and the second positioning member 6 come into contact.

[0061] S202: Pass the calibration piece 7 through the first channel 53 in the first positioning piece 5 and the second channel 63 in the second positioning piece 6.

[0062] In this step, the calibration piece 7 needs to pass through the first channel 53 in the first positioning piece 5 and the second channel 63 in the second positioning piece 6. If the calibration piece 7 cannot pass through the first channel 53 and the second channel 63 simultaneously, the installation positions of the first positioning piece 5 and the second positioning piece 6 need to be adjusted until the calibration piece 7 can pass through the first channel 53 and the second channel 63 simultaneously.

[0063] S203: Fix the first positioning member 5 to the first support plate 41, and fix the second positioning member 6 to the second support plate 42.

[0064] In this step, after the calibration piece 7 passes through the first channel 53 and the second channel 63 at the same time, the first positioning piece 5 can be fixed to the first support plate 41 and the second positioning piece 6 can be fixed to the second support plate 42 using new bolts.

[0065] Furthermore, after fixing the first positioning member 5 and the second positioning member 6, move the first sliding platform and / or the second sliding platform to separate the first positioning member 5 and the second positioning member 6. Then, insert one end of the detection channel in the detection member 8 into the first positioning part 52, and then move the first sliding platform and / or the second sliding platform. If the second positioning part 62 of the second positioning member 6 can be inserted into the other end of the detection channel, it is determined that the positions of the first positioning member 5 and the second positioning member 6 correspond, and the tooling fixture can be used normally. If the second positioning part 62 cannot be inserted into the other end of the detection channel, the positions of the first positioning member 5 and the second positioning member 6 need to be recalibrated.
