Description

Technical Field

[0001] The utility model relates to a scanning fixture, in particular to a scanning fixture for fixing a filter membrane. Background Art

[0002] Filter membranes are used to separate and concentrate solutes in processing solutions, and are also commonly used to separate colloidal suspensions. Membrane separation technology is a process that uses the difference in the permeation rate of each component in the fluid to separate components. Relying on the selective permeability of the membrane, small molecules can freely pass through the semipermeable membrane, while large molecules are not permeable to the selective membrane and are intercepted, thereby achieving the purpose of separating, purifying, and concentrating substances in multiple components.

[0003] There are two ways to fix the filter membrane. The first is to fix the filter membrane by rotating and pressing. This method can easily cause the nylon filter membrane to bulge, and the filter membrane is exposed to the external environment and is easily affected by environmental factors. The second is to clamp the filter by clips, but the upper clip is not designed to limit the position, which is easy to shake during scanning and cause particle deformation. Or O-rings are used for limiting the position, which is inconvenient to clamp and remove. The O-rings are prone to aging and damage and need to be replaced regularly. Utility Model Content

[0009] The cover glass is arranged inside the top cover assembly, and a gap is left between the cover glass and the filter membrane located in the limiting groove.

[0010] Furthermore, the first accommodating groove and the second accommodating groove are coaxially arranged circular grooves.

[0011] Furthermore, the top cover assembly includes an upper top cover and a lower top cover; the interiors of the upper top cover and the lower top cover are hollow; an embedding groove for placing a cover glass is opened on the surface of the lower top cover opposite to the upper top cover, a locking screw passes through the upper top cover and is connected to the lower top cover, and the cover glass is pressed between the upper top cover and the lower top cover; the lower top cover presses the filter membrane carrier plate onto the carrier seat along the four sides of the boss.

[0012] Furthermore, the locking assembly includes four ball-end screws; the four ball-end screws are distributed in pairs on both sides of the bearing seat, and the ball-end screws pass through the bearing seat to fix the top cover assembly.

[0013] Furthermore, the supporting seat is provided with notches around the second containing groove.

[0014] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0026] For ease of understanding, the specific process in the embodiments of the present application is described below. Figures 1 to 5 A scanning fixture for fixing a filter membrane in an embodiment of the present application comprises a supporting seat 1, a filter membrane supporting plate 2, a top cover assembly 3 and a cover glass 5; a first receiving groove 10 and a second receiving groove 11 are provided in the supporting seat 1, and the depth of the first receiving groove 10 is deeper than the depth of the second receiving groove 11; the filter membrane supporting plate 2 is clamped in the first receiving groove 10, and a boss 20 is provided on the filter membrane supporting plate 2, and a limiting groove 21 for limiting the filter membrane is provided on the upper surface of the boss; the top cover assembly 3 is limited in the second containing groove 11 and fixed in the supporting seat 1 via a locking assembly 4, and at the same time, the top cover assembly 3 presses the filter membrane supporting plate 2 onto the supporting seat 1 along the four sides of the boss 20; the cover glass 5 is arranged inside the top cover assembly 3, and a gap is left between the cover glass 5 and the filter membrane located in the limiting groove 21.

[0027] The scanning fixture for fixing the filter membrane of the utility model limits and fixes the top cover assembly 3 with the cover glass 5 embedded therein, and at the same time, there is a certain effective gap h between the cover glass 5 and the filter membrane, which has good sealing performance and can effectively prevent deformation of particles on the surface of the filter membrane during sealing, thereby ensuring the flatness of the filter membrane and the stability of movement.

[0028] Further, based on Figure 5In this embodiment, the first accommodating groove 10 and the second accommodating groove 11 are coaxially arranged circular grooves, the diameter of the second accommodating groove 11 is larger than the diameter of the first accommodating groove 10, the first accommodating groove 10 is used to limit the filter membrane carrier plate 2, and the second accommodating groove 11 is used to limit the top cover assembly 3.

[0029] Further, based on Figures 3 to 5 The top cover assembly 3 includes an upper top cover 30 and a lower top cover 31; the interiors of the upper top cover 30 and the lower top cover 31 are coaxially hollow; an embedding groove for placing the cover glass 5 is opened on the opposite surface of the lower top cover 31 to the upper top cover 30; when the cover glass 5 is placed in the embedding groove, four locking screws 32 pass through the upper top cover 30 and connect with the lower top cover 31, so that the cover glass 5 is pressed between the upper top cover 30 and the lower top cover 31, and the lower top cover 31 presses the filter membrane supporting plate 2 inside the supporting seat 1 along the four sides of the boss 20.

[0030] In addition, based on Figure 4 After the assembly, a gap h is provided between the lower surface of the cover glass 5 and the filter membrane in the limiting groove 21, so that the filter membrane will not be damaged when the top cover assembly 3 presses the filter membrane carrier plate 2, the particles on the surface of the filter membrane will not be deformed, and the filter membrane has high flatness and movement stability.

[0031] Furthermore, the locking assembly includes four ball-end screws 4; the four ball-end screws 4 are distributed in pairs on both sides of the supporting seat 1, and the ball-end screws 4 pass through the supporting seat 1 to lock the lower top cover 31 in the horizontal direction, so that the top cover assembly 3 with the cover glass 5 embedded therein is fixed on the supporting seat, which is stable and reliable when used.

[0032] Further, based on Figure 1 The supporting seat 1 is provided with a notch 12 around the second receiving groove 11, so that when the ball screw 4 is loosened from the supporting seat, the entire top cover assembly 3 can be easily removed through the notch 12, thereby facilitating the removal of the filter membrane.

[0033] based on Figures 1 to 6 When using the clamped filter membrane, the filter membrane is placed on the boss 21 of the filter membrane carrier plate 2 through the limiting groove 21, and then the filter membrane carrier plate 2 is limited in the carrier seat 1 through the first accommodating groove 10.

[0034] Place the top cover assembly 3 with the cover glass 5 in the second receiving groove 11 of the supporting seat 1, and press it downward gently so that the lower top cover 31 presses the filter membrane supporting plate 2 onto the supporting seat 1, and the ball screws 4 on both sides of the supporting seat 1 fix and lock the lateral position of the lower top cover 31. At this time, the filter membrane is fixed under the lower top cover 31, and a gap h is left between the filter membrane and the lower top cover 31.

[0035] During the membrane scanning analysis, it is only necessary to place the membrane fixing scanning fixture 51 with the membrane in any slot in the electric platform bracket 50, and the two ejector screws in the electric platform bracket 50 will automatically fix the membrane scanning fixture.

[0036] When removing the filter membrane, loosen the ball screw 4, then remove the top cover assembly 3 from the notch 12 designed around the supporting seat 1, and finally remove the filter membrane from the filter membrane supporting seat 2.

[0037] The entire installation process is convenient and labor-saving. The filter membrane is sealed in the supporting seat 1 by limiting and fixing the top cover assembly 3, and the sealing performance is good. In addition, a gap is left between the cover glass 5 and the filter membrane located in the limiting groove 21, thereby preventing deformation of particles on the surface of the filter membrane during sealing, thereby ensuring the flatness of the filter membrane and the stability of movement.
