Description

Technical Field

[0001] This invention relates to the field of medical devices, specifically to a reaction cup gripper with a mixing function. Background Technology

[0002] In chemiluminescence instruments, after adding the sample, reagents, and magnetic beads to the reaction vessel, they need to be mixed thoroughly to ensure a complete reaction. Currently, in high-throughput chemiluminescence devices, after sample addition, the gripper typically moves the reaction vessel to a separate mixing device for mixing, and then the gripper moves the mixed reaction vessel to an incubation tray for incubation. This method has two drawbacks: firstly, the gripper moves the reaction vessel multiple times, which is time-consuming and limits further increases in throughput; secondly, the separate mixing device occupies a certain amount of floor space, increasing the instrument's footprint.

[0003] Therefore, how to develop a reaction cup gripper with mixing function has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

After the sample is added to the reaction cup, the gripper directly transports the reaction cup from the sample addition point to the incubation tray for incubation. During the handling process, the solution in the reaction cup is mixed.

[0005] To achieve the above objectives, the present invention provides a reaction cup gripper with a mixing function, comprising: a gripper assembly and a mixing assembly; the gripper assembly is mounted on the mixing assembly and is used to grip and place the reaction cup; when the reaction cup on the gripper assembly needs to be mixed, the mixing assembly causes the reaction cup to swing and shake at a certain amplitude and frequency, so that the solution in the reaction cup is fully mixed.

[0019] To achieve the above objectives, such as Figure 1 As shown, the present invention provides a reaction cup gripper with a mixing function, comprising: a gripper assembly 1 and a mixing assembly 2; the gripper assembly 1 is mounted on the mixing assembly 2, and the gripper assembly 1 is used to grip and place the reaction cup 3; when the reaction cup 3 on the gripper assembly 1 needs to be mixed, the mixing assembly 2 causes the reaction cup 3 to swing and shake at a certain amplitude and frequency, so that the solution in the reaction cup 3 is fully mixed.

[0020] like Figure 2As shown, the gripper assembly 1 includes a gripper drive motor 101, a cam 102, fingers 103, and a mounting plate 106. The gripper drive motor 101 is fixed on the mounting plate 106, and the output shaft of the gripper drive motor 101 passes through the mounting plate 106 and is connected to the cam 102. The top of each finger 103 is slidably mounted on the mounting plate 106, and a clamping spring is connected between two fingers 103. The cam 102 is located between two fingers 103. The gripper assembly 1 also includes a pressure plate 104, a rotating disk, a guide post, and a compression spring 105. The top of the rotating disk is rotatably mounted on the bottom of the cam, and the bottom is connected to the guide post. The pressure plate 104 is slidably mounted on the guide post, and a compression spring 105 is provided between the pressure plate 104 and the rotating disk.

[0021] The gripper drive motor 101 rotates, causing the cam 102 to rotate. During rotation, the cam 103 can be opened. Reverse rotation allows the cam 103 to close under the action of a clamping spring. The cam 103 is adjustable according to the shape of the reaction cup 3, accommodating different shapes. The pressure plate 104, under the action of the pressure spring 105, contacts the mouth of the reaction cup 3 with appropriate pressure, effectively ensuring the stability of the reaction cup 3 during mixing and shaking.

[0022] like Figure 3 As shown, the mixing assembly 2 includes a mixing motor 201, a fixed plate 202, an eccentric shaft 203, and a mixing platform 206. The mixing motor 201 is mounted on the fixed plate 202, and its output shaft passes through the fixed plate 202 and is connected to the eccentric shaft 203. The eccentric shaft 203 is connected to the mixing platform 206 via bearings, and the mixing platform 206 is fixedly mounted to the mounting plate 106. When the mixing platform 206 shakes at a suitable frequency and amplitude, the reaction vessel 3 shakes accordingly, thereby achieving mixing of the solution within the reaction vessel 3.

[0023] The mixing assembly 2 further includes a chute 204 and a follower 205. The chute 204 is installed on one side of the fixed plate 202, and the follower 205 is installed on the mixing platform 206 and is slidably disposed in the chute 204.

[0024] The mixing motor 201 drives the eccentric shaft 203 to rotate. The eccentric shaft 203 is connected to one end of the mixing platform 206 via a bearing, and the other end of the mixing platform 206 engages with the slide groove 204 via a follower 205. The rotation of the mixing motor 201 drives the eccentric shaft 203 to rotate, thereby causing the mixing platform 206 to periodically oscillate. By adjusting the eccentricity of the eccentric shaft 203 and the rotation speed of the mixing motor 201, the frequency and amplitude of the oscillation can be adjusted, thus adjusting the mixing effect. The motion of the mixing platform 206 after one rotation of the eccentric shaft 203 is illustrated below. Figure 4 As shown.

[0025] The mixing component 2 has an external mounting interface on its fixing plate 202, which is connected to the robotic arm to move the reaction cup.

[0026] This invention provides a reaction cup gripper with a mixing function. The gripper can mix the solution in the reaction cup while transporting it. After the sample is added to the reaction cup, the gripper directly transports the reaction cup from the sample addition point to the incubation tray for incubation. During the transport process, the solution in the reaction cup is mixed.

[0027] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
