Description

Technical Field

[0001] The invention relates to the field of material detection, and in particular to a detection device. Background Art

[0002] At present, filter materials have been used in various fields of daily life and industrial production. There are many kinds of filter materials with different application scenarios.

[0003] In order to control the various performance indicators of the filter material, the filter material needs to be tested. There are many test items. For example, filter materials such as carbon cloth or HEPA filter paper need to be tested for filtration efficiency, resistance, weight, thickness, folding resistance and other indicators. Usually, the testing requires the raw materials to be divided into multiple parts and sent to different testing rooms for testing, which consumes a lot of materials. At the same time, the test data of the test items need to be manually counted, which results in more manpower and time consumption. Summary of the invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect of low efficiency of filter material detection in the prior art, thereby providing a detection device.

[0005] The present invention provides a detection device, comprising: a base station;

[0006] A guide portion, disposed on the base, comprising an upstream end and a downstream end;

[0007] A clamping portion, movably connected to the guide portion, adapted to clamp the filter material and move from the upstream end toward the downstream end;

[0008] The detection part is arranged adjacent to the base, and comprises at least a first detection structure and a second detection structure, wherein at least one of the first detection structure and the second detection structure is a non-destructive detection structure and is arranged corresponding to the upstream end of the guide part.

[0009] The second detection structure is arranged corresponding to the downstream end, and includes: a guide hole arranged in a V shape;

[0010] The clamping air pliers include a first air pliers and a second air pliers, which are arranged to protrude from the guide hole and are suitable for clamping the filter material and moving along the guide hole.

[0011] The second detection structure is an automatic folding instrument.

[0012] The first detection structure includes: a TSI detector, and / or a thickness gauge, and / or a balance.

[0013] The TSI detector, the thickness gauge and the balance are arranged corresponding to the upstream end.

[0014] The guiding part is a guiding slide rail, and the guiding slide rail is engaged with the clamping part and movably connected.

[0015] The clamping part includes: a telescopic rod, engaged with the guide part and suitable for moving along the extension direction of the guide part;

[0016] The clamping pliers are arranged at the end of the telescopic rod.

[0017] The clamping portion is also provided with a sensor.

[0018] The technical solution of the present invention has the following advantages:

[0019] 1. A detection device provided by the present invention comprises: a base; a guide portion, which is arranged on the base and comprises an upstream end and a downstream end; a clamping portion, which is movably connected to the guide portion and is suitable for clamping and placing filter materials and moving from the upstream end toward the downstream end; a detection portion, which is arranged adjacent to the guide portion and comprises at least a first detection structure and a second detection structure, at least one of which is a non-destructive detection structure and is arranged corresponding to the upstream end of the guide portion.

[0020] The clamping part clamps the filter material to be tested, moves along the guide part, and first passes through the non-destructive detection structure of the first detection structure and the second detection structure for detection, and then passes through the other one for detection. This arrangement, on the one hand, realizes the automation of multiple detections of the filter material, outputs all the detection results from one detection device at one time, improves the statistical efficiency of the filter material detection data, and saves labor costs. On the other hand, the non-destructive detection structure is set in the upstream section of the guide part, so that the filter material is first subjected to non-destructive detection, avoiding the influence of filter material damage on subsequent detection results, and improving the effectiveness and accuracy of the detection device. In addition, the detection device can complete multiple detections while using less filter material, saving filter material and improving filter material utilization efficiency. This arrangement effectively overcomes the defect of low filter material detection efficiency in the prior art.

[0021] 2. The detection device provided by the present invention, the second detection structure includes: a guide hole, which is arranged in a V shape; a clamping air clamp, including a first air clamp and a second air clamp, which are arranged to protrude from the guide hole and are suitable for clamping the filter material and moving along the guide hole.

[0022] By setting a first air clamp and a second air clamp, the filter material to be tested is clamped together and then moved in a mirror image along both sides of the guide hole set in a V shape, so that the filter material is folded and then returns to the initial position. The above process is repeated. Such a process can detect the folding resistance of the filter material. At the same time, the second detection structure is destructive to the filter material, so it is set at the downstream end of the guide part to avoid affecting the detection result of the first detection structure.

[0023] 3. The detection device provided by the present invention, the first detection structure includes: a TSI detector, and / or a thickness gauge, and / or a balance.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0038] like Figure 1 - Figure 4 The present invention provides a detection device, comprising: a base; a guide portion, which is arranged on the base and includes an upstream end 11 and a downstream end 12; a clamping portion 2, which is movably connected to the guide portion and is suitable for clamping and placing filter materials and moving from the upstream end 11 toward the downstream end 12; a detection portion 3, which is arranged adjacent to the base and includes at least a first detection structure 31 and a second detection structure 32, at least one of the first detection structure 31 and the second detection structure 32 is a non-destructive detection structure and is arranged corresponding to the upstream end 11 of the guide portion.

[0039] In this embodiment, the upstream end 11 is the end portion of the guide portion corresponding to the clamping portion 2 when the clamping portion 2 is in the initial position of the movement, and the downstream end 12 is the end portion of the guide portion corresponding to the clamping portion 2 at the end position of the single-cycle movement. Destructive testing refers to a testing method that destroys or changes the state of the filter material to be tested, making it impossible to perform subsequent testing or affecting the subsequent test results, such as testing the filter material for damage by high temperature or weighing it immediately after immersion in liquid.

[0040] The clamping part 2 clamps the filter material to be tested, moves along the guide part, and first passes through the non-destructive detection structure in the first detection structure 31 and the second detection structure 32 for detection, and then passes through the other one for detection. This arrangement, on the one hand, realizes the automation of multiple detections of the filter material, outputs all the detection results from a detection device at one time, improves the statistical efficiency of the filter material detection data, and saves labor costs. On the other hand, the non-destructive detection structure is set in the upstream section of the guide part, so that the filter material is first non-destructively detected, avoiding the influence of filter material damage on subsequent detection results, and improving the effectiveness and accuracy of the detection device. In addition, the detection device can complete multiple tests while using less filter material, saving filter material and improving filter material utilization efficiency. This arrangement effectively overcomes the defect of low filter material detection efficiency in the prior art.

[0041] In this embodiment, the first detection structure 31 is a non-destructive detection structure, the second detection structure 32 is a destructive detection structure, and the second detection structure 32 is an automatic folding instrument. As a convertible implementation, the second detection structure can also be a high temperature detector, etc.

[0042] The second detection structure 32 is arranged at the downstream end 12 of the guide part, including: a guide hole 321, which is arranged in a V shape; a clamping air clamp 322, including a first air clamp and a second air clamp, which protrude from the guide hole 321 and are suitable for clamping the filter material and moving toward each other along the guide hole 321.

[0043] In this embodiment, the guide hole 321 is arranged in an inverted V shape, and both ends are connected with vertical extension holes, and the first air pliers and the second air pliers are symmetrically arranged in the guide hole 321 .

[0044] As a convertible implementation, the first detection structure 31 is a destructive detection structure, which is arranged at the downstream end 12, and the second detection structure 32 is a non-destructive detection structure, which is arranged at the upstream end 11; as another convertible implementation, the first detection structure 31 and the second detection structure 32 are both non-destructive detection structures, and the positions of the corresponding guide parts can be freely set.

[0045] By setting a first air clamp and a second air clamp to jointly clamp the filter material to be tested, the filter material is moved in a mirror image along both sides of the guide hole 321 set in a V shape, so that the filter material is folded and then returns to the initial position. The above process is repeated. Such a process can detect the folding resistance of the filter material. At the same time, the second detection structure 32 is destructive to the filter material, so it is set at the downstream end 12 of the guide part to avoid affecting the detection result of the first detection structure 31.

[0046] The first detection structure 31 includes: a TSI detector 311, a thickness gauge 312 and a precision balance 313, and is arranged corresponding to the upstream end 11 of the guide part.

[0047] The TSI detector 311, thickness gauge 312 and balance 313 are respectively used to detect the filtration efficiency and resistance, thickness and weight of the filter material. Each detection structure is non-destructive to the filter material and does not affect the detection results of each other. Therefore, they are arranged at the upstream end 11 of the guide part, that is, they cannot affect the detection results of the second detection structure 32 at the downstream end 12, thereby improving the detection efficiency and stability of the detection device.

[0048] In this embodiment, the setting positions of the TSI detector 311, the thickness gauge 312 and the precision balance 313 can be interchanged; as a convertible implementation method, the first detection structure 31 can only be set with one or two of the TSI detector 311, the thickness gauge 312 and the precision balance 313.

[0049] In this embodiment, the guide part is a guide rail (not shown in the figure), which is unidirectionally arranged and parallel to the connecting line of the detection structures of the detection part 3. The guide rail is engaged with the clamping part 2 and is movably connected. The clamping part 2 can move along the direction in which the guide rail is arranged, and can also move a part of the distance perpendicular to the direction of the guide rail.

[0050] As a convertible implementation, the guide portion may also be an electromagnetic coil disposed in the base, which can apply a controllable electromagnetic external force in a horizontal direction to the clamping portion 2 .

[0051] In this embodiment, the clamping portion 2 includes: a telescopic rod 21 engaged with the guide portion and suitable for moving along the extending direction of the guide portion; and a clamping clamp 22 disposed at the end of the telescopic rod 21 .

[0052] The telescopic rod 21 is inserted into the guide portion of the base in the vertical direction and can be telescoped in the vertical direction. In this embodiment, the telescopic rod 21 is a sleeve.

[0053] The clamping part 2 is also provided with a position sensor. The sensor is arranged on the clamping part 2. The sensor can detect the distance and position data of the filter material and the detection positions in the first detection structure 31 and the second detection structure 32, and feed back to the clamping clamp 22 and the telescopic rod 21, so that the clamping clamp 22 can accurately transport and place the filter material.

[0054] In this embodiment, the detection device further includes a controller, which is electrically connected to the guide portion, the clamping portion 2, the detection portion 3, the sensor, etc., respectively, and the controller can be electrically connected to an external electronic device.

[0055] Working process:

[0056] Cut the carbon cloth or HEPA filter paper to be tested into a square sample of the specified size, clamp its edge with the clamp 22, start the guide rail, the sensor senses and locates to the TSI detector 311, the clamp 2 stops and releases the air clamp, the sample is placed on the sample table of the instrument, and the TSI detector 311 automatically lowers the detection head to test the filtration efficiency and resistance of the sample. After completion, the controller outputs the data to the host computer, that is, the above two test indicators are completed. TSI general test conditions: use a 0.3μmNaCl dust source, at a flow rate of 32L / min.dm2, to test the filtration efficiency and resistance of the sample.

[0057] After the TSI test is completed, the clamp 22 re-grips the sample and transfers it to the test position of the thickness gauge 312. Similarly, the sensor senses and positions the sample and places it on the sample table. The thickness gauge 312 then automatically lowers the detection head to measure the thickness of the sample. After the test is completed, the data is output to the host computer, and the thickness test of the sample is completed.

[0058] After the thickness test is completed, the clamp 22 re-grips the sample and transfers it to the test position of the precision balance 313. After the same induction positioning, the sample is placed on the sample table, and then the balance 313 measures the weight of the sample. After the test is completed, the data is output to the host computer, and the weight test of the sample is completed.

[0059] After the weight test is completed, the clamping pliers 22 re-grips the sample and transfers it to the test position of the automatic folding instrument. The first and second air clamps of the instrument clamp the left and right edges of the sample respectively, and then fold the product in half according to the running trajectory set by the guide hole 321. The test is repeated 50 times and the sample is stopped. The sample is then taken out to observe whether there is obvious breakage, and the folding resistance of the sample is manually input into the host computer.

[0060] In summary, all continuous testing items of the samples are completed, and the host computer summarizes the data to automatically generate a data table, which shortens the testing time and greatly improves the testing efficiency.

[0061] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
