Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0021] Embodiment 1

[0022] This embodiment provides a multi-channel synchronous rapid pipetting workstation, as Figures 1-4 shown. The multi-channel synchronous rapid pipetting workstation includes an operation platform 1. A placement groove block 2 is fixedly connected to the top of the operation platform 1. Multiple groups of placement racks 3 are arranged inside the top end of the placement groove block 2. A pipetting collection groove 4 is slidably connected inside the placement groove block 2. A multi-channel operation mechanism 5 is arranged on the top of the operation platform 1. A positioning mechanism 6 is arranged on the side of the operation platform 1;

[0023] During use, by setting the multi-channel operation mechanism 5, pipetting operations can be carried out quickly and synchronously, saving manpower, simplifying the work process, being simple and fast to operate, and convenient to use. By setting the positioning mechanism 6, it is convenient to perform mobile positioning, so that accurate pipetting operations can be carried out, saving time and being convenient to use. By setting the pipetting collection groove 4, the liquid spilled during the pipetting process can be collected to avoid waste of resources.

[0024] Specifically, the multi-channel operating mechanism 5 includes a top plate 51 disposed on the top of the operating platform 1. A first electric lifting rod 54 is fixedly connected to the top of the top plate 51. The output end of the first electric lifting rod 54 is fixedly connected to a lifting plate 55. A plurality of pipettes 57 are disposed at the bottom of the lifting plate 55. A piston rod 56 is movably connected inside the plurality of pipettes 57. The top end of the piston rod 56 is fixedly connected to the bottom of the lifting plate 55;

[0025] During use, the pipette 57 is inserted into the test tube placed inside the placement rack 3. The lifting plate 55 disposed at the bottom of the top plate 51 is lifted and lowered by the first electric lifting rod 54. The lifting plate 55 drives the piston rod 56 to slide inside the pipette 57, thereby sucking the liquid in the test tube into the pipette 57, completing the liquid transfer operation. A plurality of pipettes 57 are provided. The plurality of pipettes 57 can suck the liquid into the inside simultaneously, and can perform the liquid transfer operation quickly and synchronously, saving manpower, simplifying the work process, being simple and fast to operate, and convenient to use.

[0026] Furthermore, connecting rods 52 are fixedly connected to the four corners at the bottom of the top plate 51.

The fixing plate 53 and the top plate 51 are fixed through the connecting rods 52. The fixing plate 53 can be driven to move by the lifting of the top plate 51, thereby facilitating the liquid transfer operation and being convenient to use.

[0027] Even further, the number of the plurality of pipettes 57 is equal to the number of placement holes provided inside the placement rack 3, and the pipettes 57 are adapted to the number of test tubes placed inside the placement rack 3, which can avoid the operator performing the liquid transfer operation one by one, saving manpower and the time of the liquid transfer operation, and being convenient to use.

[0028] Embodiment 2

[0029] Different from Embodiment 1, during the liquid transfer operation, when the pipette 57 needs to be inserted into the test tube, there may be a positioning deviation during the process, which may affect the liquid transfer operation.

The reciprocating lead screw 62 is threadedly connected to the moving block 63 disposed outside, so that the moving block 63 is forced to slide outside the limiting rod 64, thereby facilitating the movement according to the use needs and being convenient to operate.

[0031] Specifically, a support frame 65 is fixedly connected to one side of the moving block 63 away from the operation platform 1. An installation groove 66 is formed inside the support frame 65. An electric lifting rod II 67 is fixedly connected inside the installation groove 66. The output end of the electric lifting rod II 67 is fixedly connected with a lifting connection block 68. The moving block 63 drives the support frame 65 arranged on the side to move. An installation groove 66 is formed inside the support frame 65. The electric lifting rod II 67 arranged inside the installation groove 66 is used to push the lifting connection block 68 to lift, so that the lifting connection block 68 slides inside the installation groove 66, and the stability of the movement of the lifting connection block 68 is improved through the installation groove 66.

[0032] Further, the lifting connection block 68 is slidably connected with the installation groove 66. One side of the lifting connection block 68 is fixedly connected with the top plate 51. The lifting connection block 68 is fixedly connected with the top plate 51. The top plate 51 is driven to lift through the lifting connection block 68, so as to facilitate liquid transfer positioning and is convenient to use.

[0033] It should be noted that the electric lifting rod I 54, the electric lifting rod II 67 and the servo motor are existing devices, and their working principles, dimensions and models have nothing to do with the functions of this application, so no more description will be made. The control mode of the present invention is controlled by a controller. The control circuit of the controller can be realized by simple programming by those skilled in the art. The provision of power also belongs to the common knowledge in the art. And the present invention is mainly used to protect mechanical devices, so the control mode and circuit connection of the present invention will not be explained in detail.
