Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of diaphragm detection devices, in particular to a conductive diaphragm detection device. Background Art
[0002] Conductive diaphragm is a thin film with conductive function. The charged carriers of the conductive film are scattered by the surface and interface during the transport process. When the thickness of the film is comparable to the free path of the electrons, the influence on the surface and interface will become significant. This phenomenon is called the size effect of the film, which is equivalent to a reduction in the free path of the carriers. Therefore, compared with the bulk of the same material, the conductivity of the film is smaller.
[0003] After the conductive diaphragm is produced, it is necessary to test whether it is qualified, mainly for line conduction test, button resistance test, low voltage insulation test and high voltage insulation test. The existing conductive diaphragm detection equipment requires the operator to place the conductive diaphragm on the detection table, push one end of the conductive diaphragm against the positioning block on one side of the detection table, and then move the detection probe downward to detect the conductive diaphragm. This method is manually positioned and can only determine the lateral position, but cannot determine the front and rear position. It needs to rely on the operator's experience for placement. If the placement position is inaccurate, the contact point between the detection probe and the conductive diaphragm will be incorrect, that is, the detection result will be biased.
[0004] Therefore, the present application provides a conductive film detection device to meet the needs. Utility Model Content
[0005] The technical problem to be solved by the utility model is to provide a conductive film detection device to solve the problem that the existing manual positioning can only determine the lateral position but cannot determine the front and rear positions.
[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:
[0007] A conductive diaphragm detection device comprises a base, a detection machine is fixedly connected to the top of the base, a lifting plate is movably connected to the inner cavity of the detection machine, a connecting plate is fixedly connected to the inner wall of the lifting plate, a detection probe is fixedly connected to the outer wall of the connecting plate, and a placement plate is fixedly connected to the top of the base; a positioning component is used to position the conductive diaphragm before detection, and the positioning component is respectively connected to the lifting plate and the placement plate.
[0008] Optionally, the positioning assembly includes a pushing plate slidably connected to the top of the inner cavity of the placement plate, and the pushing plate is arranged on the rear side and left and right sides of the placement plate.
[0009] Optionally, an L-shaped rod is fixedly connected to the top of the pushing plate, and a triangular block is fixedly connected to the outer wall of the lifting plate.
[0010] Optionally, one end of the L-shaped rod is slidably connected to an inclined side of the triangular block, and a limiting groove is provided on the inclined side of the triangular block.
[0011] Optionally, one end of the L-shaped plate is fixedly connected to a limiting block, and an outer wall of the limiting block is slidably connected to an inner wall of the limiting groove.
[0012] Optionally, an elastic sheet is fixedly connected to one side of the pushing plate, and the elastic sheet and the pushing plate are an integrated structure.
[0013] Optionally, a limiting steel wire is fixedly connected to the inner wall of the placement plate, and the length of the limiting steel wire is fixed.
[0014] Optionally, a positioning plate is slidably connected to the top of the inner cavity of the placement plate, and one side of the positioning plate is fixedly connected to one end of the limiting steel wire.
[0015] Optionally, one side of the positioning plate is fixedly connected to one end of the elastic sheet.
[0016] Optionally, an inclined slide plate is fixedly connected to the top of the placement plate, and the inclined slide plate is in an inclined arc shape.
[0017] Compared with the prior art, the utility model has at least the following beneficial effects:
[0018] In the above scheme, by setting a positioning component, the conductive diaphragm to be detected can be positioned before the detection probe contacts it for detection, and the positioning component is driven by the movement originally required by the detection machine, with little additional cost and greater utilization of the detection machine's own functionality. There is no need for manual positioning by the operator, which improves the detection efficiency. Each operation is accurately positioned, ensuring that the contact point between the detection probe and the conductive diaphragm is correct, reducing the possibility of deviation in the detection results.
[0019] By setting a limit wire, the movement distance of the positioning plate can be limited, that is, the positioning plate at the rear drives the conductive diaphragm to move to the required position. When the positioning plates on both sides are in contact with the conductive diaphragm, the positioning plates will stop moving to avoid squeezing the conductive diaphragm and causing it to bend, and it can ensure that the conductive diaphragm can be positioned before it contacts the detection probe.
[0020] By setting an inclined sliding plate, the inertia of the conductive diaphragm itself can be used when inserting it, so that it can contact the positioning plate at the back, so that the positioning plate can drive the conductive diaphragm to move to the required position, without having to reach the bottom of the detection probe to insert it, which increases the convenience of detecting the conductive diaphragm.

[0036] like Figures 1 to 6As shown, an embodiment of the utility model provides a conductive diaphragm detection device, including a base 1, a detection machine 2 is fixedly connected to the top of the base 1, a lifting plate 3 is movably connected to the inner cavity of the detection machine 2, a connecting plate 4 is fixedly connected to the inner wall of the lifting plate 3, a detection probe 5 is fixedly connected to the outer wall of the connecting plate 4, and a placement plate 6 is fixedly connected to the top of the base 1. Specifically, the detection machine 2 is connected to an external power supply and is a device for detecting conductive diaphragms. This is a prior art. A lifting device that can drive the lifting plate 3 to stably lift and lower the detection machine 2 is provided. The detection probe 5 is arranged in an array on the connecting plate 4 and is connected to an external circuit. The conductive diaphragm can be detected by contacting it. This is a prior art. A groove that is not closed in the front is opened on the top of the placement plate 6, and the conductive diaphragm to be detected is placed in the groove; a positioning component is used to position the conductive diaphragm before detection, and the positioning component is respectively connected to the lifting plate 3 and the placement plate 6.
[0037] like Figures 1 to 6 As shown, the positioning assembly includes a pushing plate 7 slidably connected to the top of the inner cavity of the placing plate 6, the pushing plate 7 is arranged on the rear side and the left and right sides of the placing plate 6, the top of the pushing plate 7 is fixedly connected with an L-shaped rod 8, the outer wall of the lifting plate 3 is fixedly connected with a triangular block 9, one end of the L-shaped rod 8 is slidably connected to the inclined side of the triangular block 9, the inclined side of the triangular block 9 is provided with a limiting groove 10, one end of the L-shaped plate is fixedly connected to the limiting block 11, the outer wall of the limiting block 11 is slidably connected to the inner wall of the limiting groove 10, specifically, because the height of the triangular block 9 changes, while the height of the L-shaped rod 8 does not change, the inclined surface of the triangular block 9 will push the lateral position of the L-shaped rod 8 to change, and then The inclined surface of the face triangle block 9 faces the front, the inclined surface of the left triangle block 9 faces the right, and the inclined surface of the right triangle block 9 faces the left, and they are all inclined upward. The limit block 11 and the limit groove 10 will not be separated. By setting the positioning component, the conductive diaphragm to be detected can be positioned before the detection probe 5 contacts it for detection, and the positioning component is driven by the motion originally required by the detection machine 2, with little additional cost and greater utilization of the detection machine 2's own function. There is no need for manual positioning by the operator, which improves the detection efficiency. The positioning is accurate each time the operation is operated, ensuring that the contact point of the detection probe 5 with the conductive diaphragm is correct, reducing the deviation in the detection result.
[0038] like Figure 4 and Figure 6As shown, one side of the pushing plate 7 is fixedly connected with an elastic sheet 12, and the elastic sheet 12 and the pushing plate 7 are an integrated structure. The inner wall of the placing plate 6 is fixedly connected with a limiting steel wire 13, and the length of the limiting steel wire 13 is fixed. The top of the inner cavity of the placing plate 6 is slidably connected with a positioning plate 14, and one side of the positioning plate 14 is fixedly connected to one end of the limiting steel wire 13, and one side of the positioning plate 14 is fixedly connected to one end of the elastic sheet 12. Specifically, when the pushing plate 7 drives the positioning plate 14 to move through the elastic sheet 12, since the elastic coefficient of the elastic sheet 12 is much greater than the friction between the positioning plate 14 and the placing plate 6, the elastic sheet 12 will not be deformed at this time, the limiting steel wire 13 can bend, but it cannot be elastically deformed. When the positioning of the conductive diaphragm is just completed, the limiting steel wire 13 will press the positioning plate 1 4 generates a pulling force, and the positioning plate 14 can no longer move, and the pushing plate 7 will continue to move. At this time, the elastic sheet 12 will be squeezed to deform it until the detection probe 5 contacts the conductive diaphragm. The side of the positioning plate 14 that contacts the conductive diaphragm is higher than the conductive diaphragm and has a curved arc, which is used to prevent the conductive diaphragm from warping during the detection process and make the conductive diaphragm more stable. By setting the limiting steel wire 13, the movement distance of the positioning plate 14 can be limited, that is, the rear positioning plate 14 drives the conductive diaphragm to move to the required position. When the positioning plates 14 on both sides are in contact with the conductive diaphragm, the positioning plates 14 will stop moving to avoid squeezing the conductive diaphragm and causing it to bend, and it can be ensured that the conductive diaphragm can be positioned before contacting the detection probe 5.
[0039] like Figures 1 to 4 As shown, an inclined slide plate 15 is fixedly connected to the top of the placement plate 6, and the inclined slide plate 15 is in an inclined arc shape. Specifically, the inclined slide plate 15 is inclined toward the placement plate 6. When the conductive diaphragm is placed on the inclined slide plate 15, it will automatically slide into the placement plate 6. By setting the inclined slide plate 15, the inertia of the conductive diaphragm itself can be utilized when it is placed, so that it contacts the positioning plate 14 at the rear, so that the positioning plate 14 can drive the conductive diaphragm to move to the required position, and there is no need to reach the bottom of the detection probe 5 to place it, which increases the convenience of detecting the conductive diaphragm.
[0040] The working principle of the utility model is as follows: the operator places the conductive diaphragm to be detected on the placement plate 6 along the inclined slide plate 15, the conductive diaphragm slides to the back and contacts the positioning plate 14 at the back of the placement plate 6, and starts the detection machine 2 to detect the conductive diaphragm. The detection machine 2 drives the lifting plate 3 to move downward, the lifting plate 3 drives the connecting plate 4 to move downward, and the connecting plate 4 drives the detection probe 5 to move downward. At the same time, the lifting plate 3 drives the triangular block 9 to move downward, and the limiting groove 10 on the triangular block 9 slides along the outer wall of the limiting block 11, which can drive the L-shaped rod 8 at the back to move forward, and the L-shaped rods 8 on the left and right sides move toward the middle. The L-shaped rod 8 drives the push plate 7 to slide along the bottom of the inner cavity of the placement plate 6, and pushes The plate 7 drives the rear positioning plate 14 to move forward through the elastic sheet 12, and the positioning plates 14 on the left and right sides move toward the middle. At the same time, the positioning plates 14 pull the limiting wires 13, and the rear positioning plates 14 drive the conductive diaphragm to move forward until the positioning plates 14 on both sides are in contact with both sides of the conductive diaphragm. At this time, all the limiting wires 13 are just straightened to position the conductive diaphragm at the detection position. Then the detection probe 5 continues to move downward. At this time, the pushing plate 7 will squeeze the elastic sheet 12 until the detection probe 5 contacts the conductive diaphragm to complete the detection. Then the lifting plate 3 moves upward, driving the positioning plates 14 on both sides to not contact the conductive diaphragm, and the conductive diaphragm can be taken out by sliding outward along the inclined slide plate 15.
[0041] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.
[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
