Description

Technical Field

[0001] This utility model relates to the field of fixing fixture technology, specifically to a fixing fixture for pressing reagent card box cover. Background Technology

[0002] During the production or assembly of reagent cartridges, the cover plate needs to be pressed and fixed to the chip body, and then sealed with adhesive to ensure the airtightness and functionality of the cartridge. When using the glue injection process to bond the components, manual glue injection is generally used. However, because low-viscosity glue has good flowability, it is easier to cause excessive overflow. At the same time, since the reagent cartridge cover plate needs to be pressed by hand before glue injection, the pressure is difficult to control, resulting in uneven deformation of the cover plate. This leads to poor sealing of the reagent cartridge and leakage. In addition, the manual glue injection method makes it difficult to ensure product consistency, has low production efficiency, and fails to meet market demands. Utility Model Content

Therefore, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of this utility model, unless otherwise stated, "multiple" means two or more.

[0016] like Figure 1 - Figure 7 As shown, this utility model provides a fixing fixture for pressing the cover of a reagent card box, including: a base plate 6, a pressure plate 2, a magnetic suction component, a chip body 5, and an adjustment component; The pressure plate 2 is connected to the base plate 6 via the hinge shaft 4. The base plate 6 has a limiting structure, which includes a stepped surface 13 for limiting the chip body 5 in the horizontal direction and a boss 14 for limiting the pressure plate 2 in the vertical direction. The limiting structure forms a receiving cavity for accommodating the chip body 5. An adjustment assembly is provided on the pressure plate 2. The adjustment assembly includes multiple ball positioning screws 1, each of which includes an elastic plunger 18 and a spring. The spring is provided inside the elastic plunger 18 so that the compression amount of the elastic plunger 18 is adjustable. This is used to adjust the distance between the pressure plate 2 and the base plate 6, thereby adjusting the pressing force of the pressure plate 2 on the chip body 5. The compression amount adjustment range of the elastic plunger 18 is 1mm to 2mm.

[0017] It also includes a magnetic attraction component, which includes a first magnet 10 and a second magnet 12. There are multiple first magnets 10 and multiple second magnets 12. Multiple first magnets 10 are disposed on the pressure plate 2, and multiple second magnets 12 are disposed on the base plate 6. Each first magnet 10 is correspondingly provided with a second magnet 12, and the second magnet 12 is disposed through the base plate 6.

[0018] As shown in the diagram, during installation, firstly, six ball bearing positioning screws 1 are installed onto the pressure plate 2, and then the first magnet 10 is installed onto the pressure plate 2. Multiple first magnets 10 can be glued to the back plate, and the number of first magnets 10 can be φ6 x 4.5. The installation method of the second magnet 12 is the same as that of the first magnets 10, and the number of second magnets 12 can be φ6 x 10. The second magnets 12 are installed inside the cylindrical holes opened in the boss 14 of the base plate 6. Under the action of the boss 14, the base plate 6 and the pressure plate 2 remain parallel. The chip body 5 is limited in the X and Y directions by the stepped surface 13 of the base plate 6, and in the Z direction by the ball positioning screw 1 for clamping and limiting. During installation, the user adjusts the height of the ball positioning screw 1 on the pressure plate 2 with a wrench so that the elastic plunger 18 on the ball positioning screw 1 is pressed against the chamber cover plate 3 and compressed by about 1mm. At this time, the six ball positioning screws 1 are adjusted in sequence. After the adjustment is completed, glue is applied for fastening.

[0019] In some embodiments, the dispensing machine table panel 8 is also included. The dispensing machine table panel 8 is provided with a plurality of stepped cylindrical pins 7 and connecting magnets 9. The base plate 6 is provided with positioning holes 15 corresponding to the stepped cylindrical pins 7 one by one, and the connecting magnets 9 are provided with the second magnets 12 one by one.

[0020] In the above structure, the installed chip body 5 is mounted onto the dispensing machine table panel 8 along with the overall fixture. The dispensing machine table panel 8 is provided with multiple stepped cylindrical pins 7 and connecting magnets 9. The size and number of connecting magnets 9 can be φ6X2.5. However, it is worth noting that the highest point of the connecting magnet 9 is lower than the plane of the dispensing machine table panel 8 to prevent interference. After the stepped cylindrical pins 7 and the positioning holes 15 are aligned, the connecting magnets 9 and the second magnet 12 are magnetically coupled, ensuring the stability of the overall mechanism and facilitating the next step of glue injection. At the same time, the magnetic pole selection of the first magnet 10, the second magnet 12, and the connecting magnet 9 during installation is not specifically described in this utility model, so that they can correspond to the positioning holes 15 and the second magnet 12 on the base plate 6, achieving the effect of quick connection and positioning between the fixture and the dispensing machine table. At the same time, during glue injection, this utility model is provided with glue injection holes 17 and vent holes 16, which facilitates glue injection and venting, avoids glue blockage or air bubbles, ensures glue consistency, and improves efficiency.

[0021] In some embodiments, the device further includes a chamber cover plate 3 and a one-way valve cover plate 11. Both the chamber cover plate 3 and the one-way valve cover plate 11 are disposed between the chip body 5 and the pressure plate 2. The chamber cover plate 3 is used to cover the receiving cavity. The one-way valve cover plate 11 is provided with a glue injection hole 17 and a vent hole 16. The pressure plate 2 is provided with corresponding clearance holes to avoid the glue injection hole 17 and the vent hole 16. As shown in the figure, the chamber cover plate 3 in this invention is used in conjunction with multiple ball bearing positioning screws 1, and the multiple ball bearing positioning screws 1 are evenly distributed. However, when the volume of the chamber cover plate 3 is small, the user can set a ball positioning screw 1 in the center of the chamber cover plate 3 according to actual needs, so that the chamber cover plate 3 and the chip body 5 fit more tightly, the deformation of the chamber cover plate 3 is small, and the fit is tight and without warping after glue injection. It is worth noting that the force of pressing the chamber cover plate 3 and the one-way valve cover plate 11 is adjusted according to the compression of the ball positioning screw 1, thereby achieving the problem of keeping the pressing force and pressing position of the reagent card box cover consistent.

[0022] Meanwhile, in the above embodiments, after the chamber cover plate 3, the one-way valve cover plate 11 and the chip body 5 are placed into the fixture, the corresponding positions on the pressure plate 2 are also reserved with glue injection holes 17 and vent holes 16 to facilitate smooth glue injection.

[0023] In one possible implementation, in some embodiments, the pressure plate 2 is made of a transparent material to facilitate observation of the glue application, while the base plate 6 and the dispensing machine table panel 8 are made of 6061 aluminum alloy.

[0024] In some embodiments, the shape of the stepped surface 13 of the limiting structure matches the contour of the chip body 5.

[0025] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
