Description

Technical Field

[0001] This invention relates to the field of magnetic induction detection technology, and in particular to a reliability testing device for components used in the production of security gates. Background Technology

[0002] Metal detectors are widely used in security inspections. They utilize the principle of electromagnetic induction to detect metal objects carried by people passing through. The alarm mechanism works by using sensors inside the side panels that emit and receive alternating electromagnetic fields. When a conductive metal is excited by an alternating electromagnetic field, eddy currents are generated within it. These currents emit a magnetic field with the same frequency but opposite direction to the original magnetic field. The metal detector detects the presence of nearby metal objects by detecting the presence of these eddy current signals. The transmitter emits excitation electromagnetic waves, and the receiving sensor receives the signal from the metal object. The receiving sensor extracts the signal generated by the eddy currents, amplifies it, and then triggers an alarm with sound and light when the signal reaches a set value.

[0003] The security gate has a transmitter and receiver installed inside its frame to detect passing metal. During the detection process, the sensing signal is different for different metals, and the sensing intensity varies at different locations within the frame due to the different installation positions of the transmitter and receiver. After production, the security gate needs to undergo reliability testing to avoid missing areas. Based on this, a component reliability testing device for security gate production is proposed.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] Example, refer to Figures 1-6A reliability testing device for components used in the production of security gates includes a quality inspection table 1. The quality inspection table 1 is equipped with an installation cycle unit and a full-area electromagnetic test unit. The installation cycle unit is used to install and switch the security gate frame. The full-area electromagnetic test unit is used to change the position and height of the test material to cyclically pass through the security gate, thereby triggering the magnetic field set inside the security gate throughout the entire area and realizing the reliability testing of the sensors inside the security gate.

[0032] The installation cycle unit consists of two mounting seats arranged opposite each other. The mounting seats consist of a fixed lower mounting seat 2 and an adjustable upper mounting seat 3. The fixed lower mounting seat 2 is rotatably connected to the quality inspection table 1 via a turntable. The adjustable upper mounting seat 3 can move upward, thereby changing the distance between the fixed lower mounting seat 2 and the adjustable upper mounting seat 3, thus achieving the effect of controlling the distance of the security gate frame installed on it. The mounting seat has an installation opening 4 for placing the security gate frame. The mounting seat is provided with a locking component for limiting the security gate frame. The locking component includes a connecting vertical shaft 9 rotatably set on the mounting seat. A fancy locking disc 10 is fixedly connected to the outer wall of the connecting vertical shaft 9.

[0033] It should be noted that the security gate frame is equipped with a transmitter and a receiver. The transmitter emits excitation electromagnetic waves, and the receiving sensor receives the signal of the metal object.

[0034] The mounting base is equipped with a terminal block 27 for electrical signal connection with the security gate frame. The terminal block 27 is connected to a trigger alarm device, which is an existing alarm structure of the security gate and is existing technology, so it will not be described in detail here.

[0035] When installing the security gate frame, connect the wiring terminals of the security gate frame to the wiring terminal 27 to achieve the effect of transmitting the detection signal as an electrical signal;

[0036] A spacing adjustment component is provided between the fixed lower mounting base 2 and the adjustable upper mounting base 3 to adjust the spacing between the two security gate frames;

[0037] Furthermore, the spacing adjustment component includes a threaded sleeve 11 disposed between the fixed lower mounting base 2 and the adjustable upper mounting base 3. The threaded sleeve 11 may be provided with a knob for easy rotation operation. Adjustable studs 12 are threadedly connected to both ends of the threaded sleeve 11. The adjustable studs 12 located on both sides of the threaded sleeve 11 are respectively connected to the fixed lower mounting base 2 and the adjustable upper mounting base 3.

[0038] It should be noted that by designing a spacing adjustment component to adjust the spacing between the fixed lower mounting base 2 and the adjustable upper mounting base 3, the spacing between the security gate frames installed on them can be changed, thereby meeting the needs of adjusting the detection spacing between security gate frames of different specifications during the research and development stage.

[0039] The full-range electromagnetic test unit includes a test stand 5 set on the quality inspection bench 1. A drive motor 6 is set on the test stand 5. The drive motor 6 is existing technology and will not be described in detail here. The output end of the drive motor 6 is connected to multiple test components through a drive assembly.

[0040] Furthermore, the drive assembly includes a drive ring 13 rotatably mounted on the test stand 5. The test stand 5 has a transmission cavity, the output end of the drive motor 6 passes through the transmission cavity and is fixedly connected to a drive gear 14, and the inner side wall of the drive ring 13 is provided with a drive gear ring 15 that meshes with the drive gear 14.

[0041] The test component is positioned between the fixed lower mounting base 2 and the adjustable upper mounting base 3. The drive component can synchronously drive multiple test components to rotate, thereby continuously moving the test material on the test component and thus achieving the detection effect of the security gate frame's recognition capability.

[0042] The test assembly includes a magnetic slide rail base 7. The end of the magnetic slide rail base 7 is connected to the drive ring 13 via a connecting fixing block 16. The bottom of the push slider 28 is provided with a magnetic slide rail block 17 located inside the magnetic slide rail base 7.

[0043] The magnetic slide rail base 7 and the magnetic slide rail block 17 have a magnetic attraction force, which ensures that the magnetic slide rail base 7 is stably in the fixed position when there is no external force. This avoids displacement under rotational force during the test, which would affect the accuracy of the test material.

[0044] The magnetic slide rail base 7 is connected to a position adjustment component by pushing the slider 28. Further, the position adjustment component includes two cross-arranged adjustment rods 18. A fastening bolt and nut 19 is provided at the intersection of the adjustment rods 18. The fastening bolt and nut 19 can achieve the effect of fastening the adjustment rods 18 together, so as to support the storage tray 8 at a predetermined height. A U-shaped connecting block 20 is rotatably connected to the end of the adjustment rod 18. The upper surface of the slider 28 and the lower surface of the storage tray 8 are provided with a limiting groove 21 for the U-shaped connecting block 20 to slide, so as to achieve the effect of sliding connection between the two.

[0045] By controlling the rotation speed of the drive motor 6, the test material on the tray 8 is rotated, and the speed at which the test material passes through the security gate can be controlled, thereby exploring the influence of the speed on the accuracy of the security gate detection results.

[0046] The further advantage of adopting the above is that, by setting the position adjustment component, different heights can be set for the storage tray 8 at different positions, thereby enabling different materials to pass through the security gate frame at different heights, and achieving detection of the sensing sensitivity at different positions of the installed gate frame.

[0047] The top of the position adjustment component is provided with a tray 8 for fixing test materials. Different test materials can be placed on the tray 8 according to the test requirements. The materials are fixed by L-shaped clamping plates 26. Connecting slots are opened on both sides of the tray 8. The inner wall of the connecting slot is connected to the L-shaped clamping plates 26 by connecting springs for clamping and fixing the test materials.

[0048] It is worth noting that all components of the test kit are made of plastic and rubber to avoid the influence of metal materials on the test materials.

[0049] The test stand 5 is equipped with a progressive pushing component for adjusting the horizontal position of the tray 8. The progressive pushing component includes an electric push rod 22 on the test stand 5. The output end of the electric push rod 22 is fixedly connected to an abutting arc-shaped component 23. A pushing disk 24 is fixedly installed at the bottom of the pushing slider 28. An abutting ball 25 that interacts with the abutting arc-shaped component 23 is installed on the pushing disk 24. The abutting ball 25 can achieve the effect of converting sliding friction into rolling friction.

[0050] The progressive push assembly is used. After each predetermined rotation speed, the electric push rod 22 drives the abutting arc-shaped part 23 to move. When the push plate 24 moves to the abutting arc-shaped part 23 in the next rotation, the abutting ball 25 will come into contact with the abutting arc-shaped part 23, thereby pushing the push slider 28 connected to it to move outward step by step. This continuously changes the position of the test material on the tray 8, and realizes continuous movement and adjustment of the position on the same horizontal plane to conduct comprehensive testing of the security gate.

[0051] When performing reliability testing on a security gate, the present invention places the two door frames of the security gate in the mounting opening 4, and locks the door frames of the security gate onto the mounting base by rotating the fancy locking disc 10.

[0052] The test material to be tested is placed on the tray 8 and clamped and fixed by the L-shaped clamping plate 26 on it; the height of the tray 8 is adjusted according to the testing requirements to ensure that the vertical height of the test material at different test components is different when passing through the security gate.

[0053] The control starts the drive motor 6, which drives the drive gear 14 connected to it to drive the drive gear ring 15 to rotate, thereby driving the drive ring 13 to rotate, which in turn drives multiple magnetic slide rail seats 7 to rotate, thereby driving the test material placed in the tray 8 on them to rotate. The test material will pass through the security gate frame. When it passes through, the security gate frame will alarm, which proves that the material can trigger the alarm at this position, and that the security gate can identify the test material at this position.

[0054] During rotation, the electric push rod 22 can drive the contact arc-shaped part 23 to move outward step by step. During rotation, the push disk 24 passing the contact arc-shaped part 23 will move outward under pressure, thereby realizing the continuous adjustment of the position of the magnetic slide block 17 on the magnetic slide block seat 7. Thus, at the same height, the position of the test material can be adjusted horizontally step by step to achieve comprehensive detection at the security gate at this height and ensure the reliability of the security gate.

[0055] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
