Description

Technical Field

[0001] The utility model relates to the technical field related to mechanical processing, in particular to a filter scanning platform with a tooling fixture mechanism. Background Art

[0002] A high efficiency filter is a type of air filter that has different grades; it can capture particles as small as 0.3 microns, including pollen, bacteria, viruses, and dust. High efficiency filters are commonly used in medical, laboratory, industrial, and home settings to protect people from the hazards of air pollution. Therefore, it is necessary to determine parameters such as filtration resistance, efficiency, and dust holding capacity. This test bench uses a particle counter, which can accurately measure the size and number of particles in the air. The results of the equipment test can help determine the filtration efficiency of the high efficiency filter and whether it can effectively collect pollutants in the air.

[0003] After massive search, it is found that the prior art publication number is CN216560166U, which discloses a filter scanning probe drive assembly and a high-efficiency filter scanning test bench. The three-axis drive mechanism includes an X-axis drive mechanism, a Y-axis drive mechanism and a Z-axis drive mechanism. The X-axis drive mechanism includes two parallel X-beams, and X-direction slide rails are respectively provided on the X-direction slide rails. X-slide blocks and X-slide block drive assemblies are provided on the X-direction slide rails. The Y-axis drive mechanism includes a Y-longitudinal beam, and the two ends of the Y-longitudinal beam are respectively fixedly connected to the X-slide blocks on the two X-direction slide rails. At least two Y-direction slide rails are provided on the Y-longitudinal beam, and Y-slide blocks are respectively provided on each Y-direction slide rail. A Y-slide block drive assembly is also provided on the Y-longitudinal beam. The Z-axis drive mechanism includes a screw transmission mechanism and a motor, and a scanning probe is connected to the lower part of the screw transmission mechanism. The filter scanning probe drive assembly of the utility model has high stability, can eliminate the vibration of the scanning probe when it moves, and improve the accuracy of detection.

[0004] The high-efficiency filter scanning solutions currently used in laboratories are mostly three-dimensional servo drive modules. The displacement mechanism is controlled by a controller, and the sampling head is installed on the Z-axis module. Under the control of the controller, the displacement drive mechanism realizes X-axis and Y-axis movement respectively, and the moving range is the cross-section of the filter to be tested. The Y-axis movement drives the Z-axis, and the module on the Z-axis moves up and down, driving the sampling head to move, so as to scan and sample filters at different heights. The filter size is input by the computer, and the Z-axis position is manually confirmed to be at the starting position. Then, the three-dimensional module movement is controlled by the compiled software, and the sampling head scans above the filter. The hose connected to the sampling head sends the collected gas to the particle technology device for analysis. The analysis results are fed back to the control host to generate a data report, which can generate tables or curves.

[0005] The technical solutions of the prior art generally have a complex equipment structure. If applied in small-batch filter detection scenarios, the equipment investment cost is high and the practicality is poor.

[0032] Example

[0033] like Figure 1 to Figure 6 As shown,

[0034] A filter scanning platform with a fixture mechanism includes a mobile frame 1, a bellows 2 and a filter fixture 4. The bellows 2 is installed on the inner side of the mobile frame 1. The bottom side of the bellows 2 is connected to the high-pressure blower on the outside through a ventilation pipe. The aerosol generator is connected to the ventilation pipe through a hose. The filter fixture 4 for positioning the filter 6 is installed at the air outlet on the top of the bellows 2. A sealing strip is installed at the connection between the filter fixture 4 and the bellows 2, and a sealing strip is installed at the connection between the filter 6 and the filter fixture 4. A diffuser plate 7 is also installed at the air outlet on the top of the bellows 2, and a plurality of diffuser holes are arranged on the diffuser plate 7.

[0035] Guide rails 3 are installed on the movable racks 1 on both sides of the filter fixture 4 along the Y-axis direction. The two guide rails 3 are distributed along the X-axis direction. Two three-dimensional manual adjustment fixtures 5 are arranged side by side on the filter fixture 4 along the X-axis direction.

[0036] The three-dimensional manual adjustment tool 5 includes a Z-shaped strip 8 and two rotation adjustment structures 9. The rotation adjustment structures 9 are arranged on both sides of the Z-shaped strip 8 along the Y-axis direction. The rotation adjustment structure 9 includes a threaded thread strip 10, a rotating handle 11, a slider seat 14 and a slider 15. The top of the threaded thread strip 10 can pass through the through hole on the Z-shaped strip 8 and be installed together with the rotating handle 11 above. The threaded thread strip 10 below the Z-shaped strip 8 is installed with a guide support 12. The guide support 12 includes a spring sleeve 17 and a nut seat 18. The top of the spring sleeve 17 is installed on the threaded thread strip 10 through the nut seat 18. A spring 19 is installed on the inner side of the spring sleeve 17, and a spring support seat 20 is installed at the bottom of the spring sleeve 17. The spring 19 is installed between the nut seat 18 and the spring support seat 20.

[0037] The bottom of the threaded rod 10 is mounted on the slider seat 14 below through a connecting rod 13, and the slider 15 at the bottom of the slider seat 14 is connected to the guide rail 3 below. A locking handle 16 is also installed on one side of the slider seat 14, and the locking handle 16 is connected to the inner locking block. Rotating the locking handle 16 can make the locking rod drive the locking block to move in the guide rail 3 toward one side of the Y-axis direction, and then contact the guide rail 3 to achieve locking.

[0038] A filter scanning platform with a fixture mechanism comprises a moving frame 1, a bellows 2, a guide rail 3, a filter fixture 4, a three-dimensional manual adjustment fixture 5, a filter 6 and the like.

[0039] The three-dimensional manual adjustment tooling 5 is placed on the guide rail 3 on the mobile frame; the bellows 2 is placed in the mobile bracket 1, and the side of the bellows 2 is opened, which is connected to the high-pressure blower to generate wind pressure and air volume that meet the working conditions. The positive wind flows through the internal diffuser plate 7 of the bellows and blows toward the opening of the bellows 2; the high-pressure blower is connected to the bellows with a ventilation pipe, and the aerosol generator is injected into the aforementioned ventilation pipe through a hose to generate gas that meets the test environment.

[0040] The filter fixture 4 has an opening, which is consistent with the effective area size of the filter to be tested. The filter 6 to be tested is placed on the filter fixture 4, and the position is adjusted to align with the fixture opening.

[0041] On the parallel dual-axis linear guide rail 3, move the slider 15 with a lock to the side of the filter 6, repeat the above steps to move the slider 15 on the other side and place it on the other side of the filter 6.

[0042] There are two situations in which the Z-shaped strip 8 is placed above the filter 6 .

[0043] The first case: the Z-shaped strip 8 is higher than the height of the filter. Adjust the rotating handle 11 and the guide support 12 and screw them down to the height of the filter. Under the action of gravity, the Z-shaped strip 8 will naturally fall above the filter. The folded edge width of the Z-shaped strip 8 is consistent with the size of the outer frame of a common filter. While compacting the filter, it does not block the effective area of ​​the filter element, does not affect the scanning action, and has no effect on the test results.

[0044] After the Z-shaped strip 8 is in place, adjust the rotating handle 11 and press it down onto the Z-shaped strip 8; repeat the above steps to operate the rotating handle 11 and the Z-shaped strip 8 on the other side.

[0045] The second case: the preset Z-shaped strip 8 is lower than the height of the filter to be tested, and the rotating handle 11 is screwed up to the top of the threaded strip. The effective length of the threaded strip 10 is greater than the common filter height, and the effective adjustment length is 0-400mm;

[0046] After the above steps are completed, move the Z-shaped strip 8 to the top of the filter, and place the Z-shaped strip 8 on the top and side of the filter to be tested respectively, adjust the guide support 12, and drive the spring sleeve 17, the internal spring 19 and the upper nut seat 18 to move to the lower part of the Z-shaped strip 8;

[0047] Repeat the above steps to press the filter to be tested onto the tooling.

[0048] There is a sealing strip between the above-mentioned tooling and the bellows; there is a sealing strip between the filter and the tooling to meet the environmental sealing requirements under the test conditions;

[0049] The operator uses a handheld laser dust particle counter to scan the filter and read and analyze the filter parameter data;

[0050] After the filter changes its size, the corresponding size of tooling is selected to quickly scan and detect filters of different sizes without the need for operators to change parameters or manually replace the pressing platform. The working hours for manual adjustment and controller adjustment are similar, with low requirements on personnel skills and significant hardware reduction, thereby reducing the cost of filter detection.
