Detailed Implementation

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Reference Figure 1-6 This utility model provides a semi-automatic screening and inserting pipette tip device, which includes a material handling box 1 with openings on both the top and bottom sides. A storage box 2 is provided at the bottom of the material handling box 1. An insertion plate 13 is fixedly connected to the inside of the storage box 2 and near the top. Multiple insertion holes 14 are evenly provided inside the insertion plate 13. A support plate 4 is fixedly connected to the inside of the material handling box 1 and near the top. A material distribution rack 3 is provided on the top of the support plate 4. A material handling assembly is provided inside the material handling box 1 and below the support plate 4. The material handling assembly includes a slot 15 opened on one side of the material handling box 1, a connecting plate 5 inserted into the slot 15, and multiple fixing rods 6 equidistantly fixed to the connecting plate 5 near the inside of the material handling box 1. An arrangement part 7 is formed between every two adjacent fixing rods 6.

[0026] The nozzle to be inserted is placed inside the material handling box 1. Shaking the material handling box 1 causes the nozzle to move, making it easier to insert into the arrangement section 7. At this time, the nozzle tip is facing upwards and downwards, allowing for quick arrangement of the nozzles. The movable connecting plate 5 and fixing rod 6 can be pulled out from inside the material handling box 1 to allow the nozzle to be inserted into the storage box 2. This convenient operation enables efficient nozzle insertion and is highly practical.

[0027] The material distribution rack 3 has a hollow internal structure and a material distribution assembly inside. The material distribution assembly includes two symmetrically opened slide grooves 11 inside the material distribution rack 3 and multiple material distribution plates 8 slidably connected inside the slide grooves 11. Multiple insert rods 16 are fixedly connected at equal intervals to the bottom of each material distribution plate 8. Multiple positioning grooves 17 are opened at equal intervals to the bottom of the inner surface of the two slide grooves 11. The size of the multiple positioning grooves 17 forms a structure that increases sequentially. And positioning blocks 18 that cooperate with and insert into the corresponding positioning grooves 17 are fixedly connected to both ends of the bottom of the multiple material distribution plates 8.

[0028] All the gun heads are inserted between the arrangement sections 7, and the gun heads are neatly arranged on the side near the smaller positioning groove 17. The material distribution frame 3 is moved above the support plate 4, and the insertion rod 16 at the bottom of the material distribution plate 8 can be inserted into the top of the gun head located below it. It moves sequentially to the side located in the larger positioning groove 17. When the material distribution plate 8 moves, it drives the positioning blocks 18 at both ends and the gun heads at the bottom of the insertion rod 16 to move. When the positioning blocks 18 at both ends of the material distribution plate 8 are engaged with the corresponding size positioning groove 17, the positioning operation of the material distribution plate 8 can be completed, so that the arranged gun heads can be arranged in rows to facilitate engagement with the corresponding insertion holes 14 to complete the insertion work.

[0029] To ensure the alignment of the nozzle tip with the insertion hole 14, positioning plates 10 are fixedly connected to all four sides of the material sorting box 1, which are inserted into the storage box 2 to ensure the accuracy of the placement of the material sorting box 1 and the storage box 2. A handle 9 is installed on the side of the material sorting box 1 opposite to the slot 15, which makes it easy to shake the material sorting box 1 to arrange the nozzle tip. A pull handle 12 is fixedly connected to the side of the connecting plate 5 opposite to the fixing rod 6, which makes it easy to pull the connecting plate 5 and the fixing rod 6 out of the slot 15.

[0030] The distance between the arrangement parts 7 and the diameter of the insertion rod 16 are both slightly smaller than the diameter of the tip of the gun head, so as to ensure that the gun head can be smoothly inserted into the arrangement part 7 and that the insertion rod 16 can be smoothly inserted into the inside of the tip of the gun head.

[0031] Working principle: The nozzle to be inserted is placed inside the material handling box 1. The material handling box 1 is shaken to make the nozzle move so that it can be inserted into the arrangement section 7. At this time, the top of the nozzle is facing up and the bottom is facing down, which can quickly complete the arrangement of the nozzles.

[0032] After all the gun heads are inserted into the arrangement section 7 and arranged neatly on the side near the smaller positioning groove 17, the material distribution frame 3 is moved above the support plate 4. The insertion rod 16 at the bottom of the material distribution plate 8 can be inserted into the top of the gun head located below it, and then moved sequentially to the side of the larger positioning groove 17. As the material distribution plate 8 moves, it drives the positioning blocks 18 at both ends and the gun heads at the bottom of the insertion rod 16 to move. When the positioning blocks 18 at both ends of the material distribution plate 8 are engaged with the corresponding size positioning groove 17, the positioning operation of the material distribution plate 8 can be completed, so that the arranged gun heads can be arranged in rows to facilitate engagement with the corresponding insertion holes 14 to complete the insertion work.

[0033] After accurately placing the material handling box 1 above the storage box 2, the bottom end of the gun head is inserted into the corresponding insertion hole 14. The movable connecting plate 5 and the fixing rod 6 are pulled out from inside the material handling box 1, and the gun head is inserted into the storage box 2 to complete the insertion work. It is easy to operate and can realize the efficient insertion of the gun head, making it highly practical.

[0034] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
