Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] To address the technical problem of the limited functionality of existing cell preparation and staining machines' material handling devices, this invention provides a multifunctional material handling device that can not only grip and hold glass slides, but also grip and hold cell sedimentation chambers and filters, thus offering more comprehensive functions.

[0020] It should be noted that the multifunctional material handling device described in this utility model is used in, but not limited to, cell slide staining machines. For ease of explanation, this utility model only uses the application of the multifunctional material handling device in a cell slide staining machine as an example. The principle of the multifunctional material handling device in other testing equipment is essentially the same as that in the cell slide staining machine, and will not be described in detail here.

[0021] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the multifunctional material handling device provided in this embodiment of the utility model. Figure 2 yes Figure 1 A magnified view of a portion of the image. The multi-functional material handling device includes a mounting frame 1 and a material handling mechanism 2.

[0022] The material handling mechanism 2 includes a gripper 21 and a chuck 22. The gripper 21 is mounted on the mounting frame 1 and has two opposing grippers 211, which can move closer or further apart. The gripper 21 has an actuating mechanism that can drive the grippers 211 to move. This movement can be a movement in which the two grippers 211 move closer or further apart; or one gripper 211 can remain stationary while the other gripper 211 moves closer or further apart.

[0023] Two grippers 22 are respectively connected to two jaws 211. The grippers 22 are L-shaped, comprising an integrally connected vertical section 221 and a horizontal section 222. An arc-shaped groove 221a and a V-shaped groove 222a are formed on the opposite sides of the two grippers 22. The arc-shaped groove 221a is located on the vertical section 221 and arranged along its length, while the V-shaped groove 222a is located on the horizontal section 222 and arranged along its length. The two V-shaped grooves 222a can cooperate to grip glass slides, and the two arc-shaped grooves 221a can cooperate to grip cell sedimentation chambers and filters. This allows for the gripping of various items and improves structural integration.

[0024] In some embodiments, the vertical segment 221 is generally arranged vertically, and the horizontal segment 222 is generally arranged horizontally. The upper end of the vertical segment 221 is detachably connected to the gripper 211.

[0025] See you again Figure 1 In some embodiments, this multifunctional material handling device further includes a rotating mechanism 3, which includes a rotating driver 31 and a rotating drive shaft 32. The rotating driver 31 is fixedly mounted on the mounting frame 1, and the rotating driver 31 can be a suitable type of motor. The rotating driver 31 is connected to the gripper 21 via the rotating drive shaft 32 to drive the gripper 21 to rotate, thereby realizing the function of removing the cell sedimentation chamber.

[0026] Based on the above embodiments, the mounting bracket 1 has a mounting hole through which the rotation drive shaft 32 passes. The rotation mechanism 3 also includes a bearing 33, and the rotation drive shaft 32 is connected to the inner wall of the mounting hole through the bearing 33.

[0027] Please see Figure 3 and Figure 4 , Figure 3 yes Figure 1 Schematic diagram of the suction mechanism; Figure 4 yes Figure 3 A cross-sectional view of the suction structure.

[0028] In some embodiments, the multifunctional material handling device further includes a suction mechanism 4, which includes a TIP suction tube 41. The TIP suction tube 41 is vertically arranged and connected to the mounting bracket 1. The lower end is used to connect to the TIP suction head, and the upper end is used to connect to the negative pressure generating device of the dyeing machine to generate suction force so that the TIP suction head can draw liquid.

[0029] Based on the above embodiment, the suction mechanism further includes a housing 42 and a spring 43. The upper end of the housing 42 is connected to the mounting bracket 1. The TIP tip tube 41 passes through the mounting bracket 1 and the housing 42 and is slidably connected to the mounting bracket 1 and the housing 42. A retaining ring 411 is formed on the side wall of the TIP tip tube 41. The retaining ring 411 is located inside the housing 42. The lower surface of the retaining ring 411 can abut against the inner wall of the housing 42, and the upper surface can abut against the mounting bracket 1, so as to limit the movement stroke of the TIP tip tube 41 between these two. The spring 43 is sleeved on the TIP tip tube 41 and abuts against the mounting bracket 1 and the upper surface of the retaining ring 411 respectively. The elastic force of the spring 43 pushes the retaining ring 411 to abut against the housing 42. When the TIP tip tube 41 is inserted into the TIP tip under the action of the external lifting device, the TIP tip tube 41 can also move upward to compress the spring 43 until it moves to the highest point, and the TIP tip tube 41 is tightly inserted into the TIP tip.

[0030] Based on the above embodiments, the suction mechanism 4 also includes a displacement detection sensor 44 connected to the housing 42. The detection end of the displacement detection sensor 44 is located inside the housing 42 to detect the displacement of the TIP tip insert 41, thereby determining whether the TIP tip insert 41 and the TIP tip are tightly inserted.

[0031] Please see Figure 5 and Figure 6 , Figure 5 yes Figure 1 A schematic diagram of the middle sealing mechanism; Figure 6 yes Figure 5 A cross-sectional view of the middle cover structure.

[0032] In some embodiments, the multifunctional material handling device further includes a cover slide mechanism 5, which includes a connector 51, a coverslip suction cup 52, and a coverslip detection sensor 53. The connector 51 is connected to the mounting bracket 1. The connector 51 forms a gas channel 51A, with an inlet and an outlet formed on the surface of the connector 1. The coverslip suction cup 52 is connected to the inlet, and the outlet is used to connect to the negative pressure generating device of the staining machine, so that the coverslip suction cup 52 generates suction to hold the coverslip. The coverslip detection sensor 53 is connected to the connector 51, and its detection end is arranged side by side with the coverslip suction cup 52 to detect the presence of the coverslip.

[0033] In this embodiment, two coverslip suction cups 52 are arranged side by side to more stably hold the coverslip, and the detection end of a coverslip detection sensor 53 is located between the two coverslip suction cups 52. When the coverslip suction cup 52 approaches the coverslip, the coverslip detection sensor 53 detects the presence of the coverslip and sends a signal to the controller of the staining machine. The controller then controls the negative pressure generating device to generate negative pressure, causing the coverslip suction cup 52 to hold the coverslip.

[0034] Based on the above embodiment, the connector 51 is rotatably connected to the mounting frame 1, and the sealing mechanism 5 also includes an elastic element 54, which connects the mounting frame 1 and the connector 51. This allows the connector 51 to have a certain degree of rotational freedom, preventing the cover glass from being crushed.

[0035] This invention also provides a cell slide staining machine, including the aforementioned multifunctional material handling device.
