Description

Technical Field

[0001] This invention relates to the field of coil magnetic force detection, specifically to an electromagnetic repulsion detection device for an electromagnetic latch. Background Technology

[0002] With the development of technology, electromagnetic latches have been widely used in daily life and industry. During the production of electromagnetic latches, it is necessary to test the electromagnetic repulsion force of the coils within the latches to ensure their quality. Currently, coil testing is mostly done manually, with operators visually assessing the effectiveness of the electromagnetic repulsion force by checking if the latch opens successfully. This testing process only provides a qualitative analysis of the coil's condition, lacking a quantitative analysis of the specific magnitude of the electromagnetic repulsion force. The lack of concrete data quantification results in insufficient evidence and fails to meet the need for quantitative assessment. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an electromagnetic repulsion detection device for an electromagnetic latch, which can quantitatively detect the electromagnetic repulsion of the latch coil and adopt a semi-automatic operation mode.

[0004] The technical solution adopted by the present invention to solve the above problems is as follows: an electromagnetic repulsion force detection device for an electromagnetic latch, comprising a six-division servo turntable, wherein the six-division servo turntable is uniformly arrayed along the circumference with a manual loading station, a manual wiring station, a heating station, a bending station, a testing station, and a manual unloading station. The manual loading station is used to manually load the latch coil to be tested. The manual wiring station is used to manually electrically connect the latch coil to be tested and attach heat shrink tubing. The heating station is used to heat the heat shrink tubing to ensure the stability of the electrical connection. The bending station is used to bend the terminals of the electrical connection to complete the wire connection of the latch coil and avoid interference at the testing station. The testing station is used to detect the electromagnetic repulsion force of the latch coil. The manual unloading station is used to manually unload the latch coil after testing.

[0005] Compared with existing technologies, the advantages of this invention are as follows: Through the design of a six-section servo turntable, the electromagnetic repulsion detection of the latching coil is completed in six stations. After each station completes its work, the six-section servo turntable rotates 60° to allow the material to enter the next station for further processing. The manual loading, manual wiring, and manual unloading stations are manual stations, while the heating, bending, and testing stations are automatic stations, thus forming a semi-automatic testing device. This improves testing efficiency and reduces labor costs. The manual wiring, heating, and bending stations are used to complete the electrical connection of the latching coil, and then the testing station quantitatively detects the electromagnetic repulsion of the latching coil, quantifying the detection data to meet customer needs.

[0006] As an improvement of the present invention, six test mounting components are evenly arrayed along the circumference on the six-division servo turntable. During the rotation of the six-division servo turntable, a test mounting component is provided at each of the manual loading station, manual wiring station, heating station, bending station, testing station, and manual unloading station. The test mounting component includes a mounting base for mounting the latch coil. Through this improvement, the latch coil can be positioned and installed at the six stations, ensuring the positioning stability of the latch coil at the six stations.

[0007] As an improvement of the present invention, the test mounting assembly further includes a positioning plate, which is disposed on the side of the mounting base. One end of the positioning plate abuts against the terminal block on the latching coil to position the latching coil, and the other end of the positioning plate abuts against a spring-loaded pin to ensure that the positioning plate is pressed against the latching coil. With this improvement, to facilitate the loading and unloading of the latching coil within the mounting base, the connection between the mounting base and the latching coil uses a clearance fit, which may result in the latching coil not being sufficiently fixed within the mounting base. During the rotation of the six-point servo turntable, the latching coil is prone to deflection and slight eccentric displacement. Through the design of the positioning plate and the spring-loaded pin, after the latching coil is installed in the mounting base, the positioning lock abuts against the latching coil under the action of the spring-loaded pin, thereby ensuring the stability of the latching coil and avoiding deflection and slight eccentric displacement of the latching coil during the rotation of the six-point servo turntable.

[0008] As an improvement of the present invention, the test installation assembly further includes an electrical connection terminal, one end of which is connected to a positive wire and a negative wire. At the manual wiring station, the positive wire and the negative wire are respectively connected to two terminals on the latching coil. A heat shrink tubing is fitted at the connection point between the positive wire, the negative wire and the terminal. With this improvement, during the latching coil testing process, it is necessary to electrically connect the terminals of the latching coil. Similarly, when assembling the latching coil into an electromagnetic latch, it is also necessary to electrically connect the terminals of the latching coil. This allows for direct assembly of the latching coil with the positive and negative wires. After the test is completed, the latching coil with the connected positive and negative wires can be directly assembled into an electromagnetic latch, avoiding repeated electrical connections at the terminals, thus avoiding repetitive operations and improving work efficiency. Therefore, the electromagnetic latch is directly assembled according to the standard of latch coil assembly, and the heat shrink tubing is sleeved on the connection between the positive wire, the negative wire and the terminal block, so that the heat shrink tubing can be heated at the heating station to cure and protect the connection between the positive wire, the negative wire and the terminal block.

[0009] As an improvement of the present invention, the terminal block is placed vertically, and the heating station is equipped with a hot air gun with the hot air nozzle of the hot air gun being set horizontally. With this improvement, if the latching coil is heated, the resistance of the latching coil will increase, thereby affecting the electromagnetic repulsion detection structure of the latching coil. Therefore, by placing the terminal block vertically and the hot air nozzle of the hot air gun horizontally, the direct heating of the latching coil is avoided when heating the heat shrink tubing sleeved on the terminal block, thus ensuring the accuracy of the detection.

[0010] As an improvement of the present invention, the hot air gun is movably connected to a slide rail, which is inclined. Through this improvement, the hot air gun can be moved in the heating station. When the six-division servo turntable rotates, the hot air gun is moved away from the test installation components, avoiding interference between the hot air gun and the rotation of the six-division servo turntable.

[0011] As an improvement of the present invention, the bending station is equipped with a bending assembly for horizontally bending and shaping the terminal block. The bending assembly includes a connecting seat, an assembly lifting cylinder, a leveling lifting cylinder, a bending positioning cylinder, and a bending cylinder. The assembly lifting cylinder is fixedly connected to the upper end of the connecting seat to drive the connecting seat to move up and down. The bending positioning cylinder is located at the lower end of the connecting seat and at one end of the terminal block to be bent. The bending positioning cylinder extends and retracts horizontally. The extension end of the bending positioning cylinder is equipped with a positioning piece. The bending cylinder is located at the lower end of the connecting seat and at the opposite end of the terminal block to be bent. The bending cylinder extends and retracts horizontally. The bending and positioning cylinder has a bending plate at its telescopic end, which is positioned above the positioning plate. The leveling and lifting cylinder is fixedly connected to the connecting seat and positioned above the terminal block. After the positioning plate and bending plate bend the terminal block, the terminal block is horizontally pressed and shaped. This improvement enables the bending operation of the terminal block and ensures that the bent terminal block is horizontal. First, the bending design of the terminal block is a requirement for the installation of the latch coil in the electromagnetic latch. Second, the bending design of the terminal block not only reduces the probability of interference caused by the terminal block during the testing station, but also reduces the probability of the heat-shrinkable tubing sliding on the terminal block after heat shrinking.

[0012] As an improvement of the present invention, the test station is equipped with a test cylinder, and the telescopic end of the test cylinder is fixedly connected to two elastic probes. The two elastic probes are inserted into the electrical connection terminal and electrically connected to the positive wire and the negative wire respectively. The two elastic probes are connected to the power supply. Through this improvement, the electrical connection of the latching coil is realized.

[0013] As an improvement of the present invention, the testing station is equipped with a testing assembly, which includes a testing probe positioned below the latching coil and on a pressure sensor mounted on a sensor lifting cylinder. A magnet is magnetically attached to the bottom of the mounting base, the magnetic field axis of which coincides with the magnetic field axis formed by the latching coil. The bottom of the mounting base has an embedding groove for accommodating the magnet, which is adhered to a magnet holder. The magnet holder is movably connected within the embedding groove. Through this improvement, during testing, the design of the testing probe, pressure sensor, and magnet ensures that after the latching coil is energized, it generates a magnetic field, utilizing the magnetic... The principle of like poles repelling each other creates a repulsive force on the magnet. The magnet then transmits this repulsive force to the pressure sensor through the test probe, allowing the pressure sensor to read the electromagnetic repulsion data. When the latch coil is not energized, the magnet adheres to the mounting base using its own magnetic field. The sensor lifting cylinder design enables the vertical movement of the pressure sensor and test probe at the test station. When the six-division servo turntable rotates, the pressure sensor and test probe are moved away from the test mounting components, preventing interference between the pressure sensor, test probe, and the six-division servo turntable. The design of the magnet base moving and connected in the embedded groove ensures the stability of the magnet base movement and prevents wear between the magnet and the mounting base.

[0014] As an improvement of the present invention, the test assembly further includes a drag-reducing magnetic cover plate. The drag-reducing magnetic cover plate is movably connected above the latching coil by a cover plate lifting cylinder. The drag-reducing magnetic cover plate is provided with a clearance groove for avoiding the wiring terminals. Through this improvement, by bringing the drag-reducing magnetic cover plate close to the latching coil, the magnetic field can be concentrated, focusing the outwardly diffused magnetic field at the end of the latching coil near the drag-reducing magnetic cover plate onto the drag-reducing magnetic cover plate. This reduces the range of the outwardly diffused magnetic field, thereby reducing magnetic resistance and ensuring the accuracy of the electromagnetic repulsion test and the sufficiency of the repulsive force pushing the magnet towards the pressure sensor. It also avoids the intermittent instability of the intermediate magnetic circuit caused by the outward diffusion of the magnetic field, ensuring the stability of the electromagnetic repulsion force. During the measurement process, the fluctuation range of the data is reduced. At the same time, the drag-reducing magnetic cover plate, through its design of pressing against the latching coil, avoids the phenomenon that the latching coil is moved away from the pressure sensor due to the reaction force of the electromagnetic repulsion, ensuring the accuracy of the measurement.
