Description

Technical Field

[0001] The utility model relates to the field of assembly equipment, and particularly to an assembly mechanism for a sealing bowl and a sealing gasket of a plasma separation cup. Background Art

[0002] A plasma separation cup is a laboratory device used for separating blood components. It uses centrifugal force to separate whole blood into different components, mainly separating plasma from other blood components (such as red blood cells, white blood cells, and platelets). Plasma separation cups are usually operated by centrifuges. A blood sample is placed in the separation cup, and then through the centrifugal force generated by high-speed rotation, components with different relative densities are layered. Since plasma has a lower density, it will float on the upper layer, while other cell components will settle at the bottom.

[0003] For the assembly method of a plasma separation cup, the authorized announcement number CN105664537B discloses a method for assembling a blood component separation cup, and its specific steps are as follows: First step: Assemble the upper cover and the lower cover into fitting A; assemble the sealing gasket and the sealing bowl into fitting B; assemble the inner core and the outer core into fitting C, and ultrasonically weld fitting C assembled in the first step; Second step: Assemble the cup body, fitting A and fitting B assembled in the first step to form fitting D; Third step: Assemble fitting D assembled in the second step and the stationary head to form fitting E; Fourth step: Ultrasonically weld fitting E assembled in the third step; Fifth step: Ultrasonically weld the welded fitting E, the welded fitting C, and the cup bottom to complete the entire assembly of the blood component separation cup; Sixth step: Send the welded separation cup to a dynamic detector for machine inspection. In the first step, the inner circle of the large end of the sealing bowl is matched with the high frustum of the sealing gasket, so that the sealing gasket and the sealing bowl are assembled into fitting B.

[0004] However, in the prior art, in many cases, the inner circle of the large end of the sealing bowl is directly installed downward on the high frustum of the sealing gasket by using an assembly mechanism. However, since the inner circle size of the sealing ring is generally smaller than the outer diameter of the high frustum of the sealing gasket, it is difficult to ensure that each sealing bowl can be accurately sleeved on the high frustum of the sealing gasket during the assembly process, that is, this assembly method leads to a reduction in the assembly success rate, and further leads to an increase in the defective rate of the product.

[0005] Therefore, it is necessary to improve the prior art. Content of the Utility Model

[0025] The following further elaborates on the utility model in conjunction with the accompanying drawings and specific embodiments. The following description is merely exemplary and does not limit the protection scope of the utility model.

[0026] As Figures 1-5 shown, a sealing bowl and sealing gasket assembly mechanism for a plasma separation cup includes a machine platform 1, a movable plate 2 movably installed on the machine platform 1 in the front and rear directions, a front and rear drive device 3 installed on the machine platform 1 and used to drive the movable plate 2, and an insertion rod 4 assembly and a baffle 6 assembly respectively installed on the movable plate 2.

[0027] Among them, as Figures 1-4 shown, the insertion rod 4 assembly includes an insertion rod 4 that can move up and down and a first drive device 5 installed on the movable plate 2 and used to drive the insertion rod 4. Specifically, the first drive device 5 can be used to drive the insertion rod 4 to insert into the central hole of the sealing bowl 13 and drive the middle part 131 of the sealing bowl 13 to move downward or upward, and the side wall of the sealing bowl 13 can be flipped.

[0028] As Figures 1-4 shown, the baffle 6 assembly includes a baffle 6 that can move up and down and a second drive device 7 installed on the movable plate 2 and used to drive the baffle 6; a perforation 61 penetrating up and down is provided on the baffle 6, and the insertion rod 4 is inserted through the perforation 61. Specifically, the baffle 6 can be used to press on the periphery of the sealing bowl 13 during the assembly of the sealing bowl 13 and the sealing gasket 14, so that when the insertion rod 4 is pulled out upward, the side wall of the sealing bowl 13 can be flipped and restored and can be correspondingly clamped on the high frustum 141 of the sealing gasket 14.

[0029] As Figures 1-4As shown, for the inserting rod 4, its specific structure is as follows: The inserting rod 4 includes a first inserting portion 41, a second inserting portion 42, and a connecting portion 43 that are connected in sequence from bottom to top; the first inserting portion 41 has a frustum of a cone structure with a wider upper part and a narrower lower part; both the second inserting portion 42 and the connecting portion 43 have a cylindrical structure, and the diameter of the connecting portion 43 is greater than the diameter of the second inserting portion 42; the diameter of the second inserting portion 42 is equal to the width of the top of the first inserting portion 41; the connecting portion 43 is used to connect with the output end of the first driving device 5. By setting the lower end of the inserting rod 4 into a frustum of a cone structure, the bottom of the inserting rod 4 can be more easily inserted into the central hole of the sealing bowl 13, and it is not easy to have the situation of material jamming; the second inserting portion 42 is used to be stuck into the central hole of the sealing bowl 13. Of course, the size of the central hole of the sealing bowl 13 is slightly smaller than the diameter of the second inserting portion 42, so that the periphery of the central hole of the sealing bowl 13 can be elastically clamped on the second inserting portion 42; and the bottom surface of the connecting portion 43 is used to abut against the top surface around the central hole of the sealing bowl 13, so that it can be used to press down the middle part 131 of the sealing bowl 13 subsequently.

[0030] As Figure 3 shown, in this embodiment, there are also two slide rails 8 and two sliders 9; the two slide rails 8 are respectively installed on both sides of the machine table 1; the two sliders 9 are respectively installed on the two slide rails 8 so as to be movable back and forth, and the two sliders 9 are respectively connected to both sides of the movable plate 2. By setting the mutually matching slide rails 8 and sliders 9, the stability of the movable plate 2 during movement can be greatly improved.

[0031] In this embodiment, the front and rear driving device 3 is a cylinder. In addition, both the first driving device 5 and the second driving device 7 are also cylinders. However, those skilled in the art should know that for the above driving devices, they can also use a motor as the driving source, which will not be elaborated here.

[0032] As Figure 3 shown, in this embodiment, a connecting block 10 is connected to the output end of the first driving device 5; a plurality of inserting rods 4 are installed on the connecting block 10; a plurality of through holes 61 matching the plurality of inserting rods 4 are also provided on the baffle 6. Therefore, the inserting rod 4 is connected to the first driving device 5 through the connecting block 10. Thus, after setting the connecting block 10, one first driving device 5 can drive a plurality of inserting rods 4 to move up and down simultaneously, and the plurality of inserting rods 4 can operate on a plurality of workpieces to improve the processing efficiency.

[0033] As Figures 1-4As shown, in this embodiment, there is also a vibrating bowl 11 and a material-gripping manipulator 12; the vibrating bowl 11 is installed on the machine table 1 and is used to output the sealing bowl 13; the material-gripping manipulator 12 is installed on the movable plate 2 and is used to grip the sealing bowl 13 at the outlet of the vibrating bowl 11. By providing the vibrating bowl 11, it can be used to conveniently output the sealing bowl 13, and the material-gripping manipulator 12 is used to grip the sealing bowl 13 onto a preset positioning jig.

[0034] Combined with Figure 5 , the following introduces the specific working principle of the present invention for understanding the present invention:

[0035] First: The feeding mechanism sends the sealing gasket 14 to a preset position;

[0036] Next: As shown in the first figure of Figure 5 , the material-gripping manipulator 12 grips the sealing bowl 13 output by the vibrating bowl 11 onto a preset positioning jig, and at this time, the sealing bowl 13 is directly below the insertion rod 4;

[0037] Next: As shown in the second figure of Figure 5 , the first driving device 5 drives the insertion rod 4 to move downward until the insertion rod 4 is inserted into the central hole of the sealing bowl 13, and finally the bottom surface of the connecting portion 43 pushes down the top surface of the sealing bowl 13, causing the middle portion 131 of the sealing bowl 13 to move downward and the inner wall of the sealing bowl 13 to turn outward (i.e., the inner wall becomes the outer wall); at this time, the outer wall of the sealing bowl 13 has a structure that is wider at the top and narrower at the bottom, that is, in the state shown in the second figure of Figure 5 ;

[0038] Next: As shown in the third figure of Figure 5 , since the periphery of the central hole of the sealing bowl 13 will clamp the insertion rod 4 by elasticity, when the first driving device 5 drives the insertion rod 4 to move upward by a certain distance, the sealing bowl 13 will rise synchronously; then the front and rear driving device 3 drives the movable plate 2 to move backward to a preset position, and at this time, the sealing bowl 13 is directly above the sealing gasket 14;

[0039] Next: As shown in the third figure of Figure 5 , the first driving device 5 drives the insertion rod 4 to move downward until the insertion rod 4 is inserted into the central hole of the sealing gasket 14, and the lower end of the turned-over sealing bowl 13 is inserted into the central hole of the sealing gasket 14. Since the width of the lower end of the sealing bowl 13 at this time is smaller than the width of the central hole of the sealing gasket 14, it is very easy for the lower end of the sealing bowl 13 to be inserted into the central hole of the sealing gasket 14, that is, it can very conveniently preliminarily position the sealing bowl 13;

[0040] Next: As shown in Figure 5As shown in the fourth figure among them, after the plug rod 4 moves in place, the second driving device 7 drives the baffle 6 to move downward until the baffle 6 presses around the sealing bowl 13; then, the first driving device 5 drives the plug rod 4 to move upward, that is, the plug rod 4 is withdrawn, thereby driving the middle part 131 of the sealing bowl 13 to move upward, and further causing the side wall of the sealing bowl 13 to flip and restore simultaneously; when the plug rod 4 is completely withdrawn, the sealing bowl 13 is correspondingly restored, and after the sealing bowl 13 is restored, the inner circle at its lower end is also correspondingly and fittingly sleeved on the high round table 141 of the sealing gasket 14. Immediately afterwards, both the baffle 6 and the plug rod 4 start to reset, and the feeding mechanism sends the assembled workpiece to the next process.

[0041] In summary, the present utility model can improve the assembly accuracy and success rate of the sealing bowl 13 and the sealing gasket 14 by setting the mutually cooperating plug rod assembly and baffle assembly, and thus can improve the yield rate of the product. Specifically, the present utility model uses the plug rod 4 to push the side wall of the sealing bowl 13 to flip, and after the sealing bowl 13 flips, it will change into a structure with a wider upper part and a narrower lower part, so that each sealing bowl 13 can be very conveniently inserted into the central hole of the sealing gasket 14 without being prone to deflection; then, after using the baffle 6 to press around the sealing bowl 13, during the process of the plug rod 4 flipping and restoring, the sealing bowl 13 can be synchronously tightened on the high round table 141 of the sealing gasket 14, that is, the assembly of the sealing bowl 13 and the sealing gasket 14 is completed. The process is simple and fast, and it ensures that each sealing bowl 13 and the sealing gasket 14 can be accurately assembled.

[0042] The present utility model is not limited to the above embodiments. If various modifications or deformations of the present utility model do not depart from the spirit and scope of the present utility model, and if these modifications and deformations are within the scope of the claims of the present utility model and equivalent technical scope, then the present utility model also intends to include these modifications and deformations.
