Description

Technical Field

[0001] The utility model relates to magnetic core production equipment, in particular to a multi-station magnetic core testing machine, belonging to the technical field of equipment. Background Art

[0002] In the process of producing amorphous magnetic cores, it is necessary to test their related performance, such as inductance parameters, volt-ampere characteristics, etc. During the test, the magnetic cores are usually sorted and then enter the test station in turn (generally, they are transported to the test station in a step-by-step manner). At the test station, the copper needle contact of the test is driven by a linear drive mechanism to pass through the hole of the magnetic core and contact another fixed conductive contact. The copper needle end and the fixed contact are connected to the tester to measure the inductance value of the magnetic core. There are also multiple related schemes for magnetic core testing in Chinese patent applications, such as Chinese patent application No. 20232160482 6X discloses an inductor testing machine. The magnetic core test in the prior art is generally a single-station test, that is, one is tested at a time. This method is inefficient and the equipment wears out quickly, making it difficult to adapt to large-scale low-cost production requirements. The magnetic core is an industry with fierce price competition. The level of labor costs in its production is often the decisive factor in determining whether it can be profitable. Chinese patent application No. 2022224352074 discloses a dual-station magnetic core inductor automatic testing machine that can perform tests at two stations, but the equipment is relatively complex, occupies a large area, and the efficiency improvement is not very obvious. Summary of the invention

[0005] Furthermore, a track in the up-down direction is fixedly mounted on the first mounting plate, a sliding block is slidably fitted on the track, and the second mounting plate is fixedly connected to the sliding block.

[0006] Furthermore, the up and down driving mechanism is a lifting cylinder.

[0007] Furthermore, a material detection switch is installed on the front and rear sides of the grooved track, and the two material detection switches correspond to the first and last test stations respectively.

[0008] Furthermore, a material blocking cylinder is fixedly installed on one side of the slotted track behind the tail end test station, and the material blocking cylinder rod can block the magnetic core on the slotted track when it is extended.

[0009] Furthermore, the number of the fixed contacts is 8.

[0016] In order to more fully explain the implementation of the utility model, implementation examples of the utility model are provided. These implementation examples are only for the purpose of illustrating the utility model and do not limit the scope of the utility model.

[0017] The utility model is further explained in detail in conjunction with the accompanying drawings, in which the marks are: 1: first mounting plate; 2: second mounting plate; 3: lifting cylinder; 4: sorting conveyor belt; 5: copper needle contact; 6: fixed contact; 7: linear module; 8: material blocking cylinder; 9: front material detection switch; 10: rear material detection switch; 11: grooved track; 12: long slit; 13: track; 14: sliding block.

[0018] As shown in the attached drawings, a multi-station magnetic core testing machine is installed behind the sorting conveyor belt. The sorting conveyor belt is an existing technology, including a frame, a grooved track 11 is fixedly installed on the frame, and the grooved track connects the sorting conveyor belt. A material detection switch is installed on the front and back sides of the grooved track. The two material detection switches correspond to the first and last test stations respectively. The two material detection switches in the figure are the front material detection switch 9 and the rear material detection switch 10. The material detection switch can use the existing proximity switch, and the material detection switch is connected to the controller. A material blocking cylinder 8 is fixedly installed on one side of the grooved track behind the tail end test station. When the rod of the material blocking cylinder is extended, it can block the magnetic core on the grooved track.

[0019] A long slot 12 is provided on the bottom surface of the slot track along the length direction of the slot. A set of linear modules 7 that can move in the front-to-back direction is installed on one side of the slot track. A first mounting plate 1 is fixedly connected to the slider of the linear module. A plurality of fixed contacts 6 distributed front-to-back are fixedly installed on the first mounting plate under the long slot. In this embodiment, the number of the fixed contacts is 8.

[0020] An up-and-down driving mechanism is fixedly mounted on the first mounting plate. In this embodiment, the up-and-down driving mechanism is a lifting cylinder 3. The up-and-down driving mechanism can also be an oil cylinder, a linear slider, etc. The action end of the up-and-down driving mechanism is fixedly connected to the second mounting plate 2. A track 13 in the up-and-down direction is fixedly mounted on the first mounting plate 1. A sliding block 14 is slidably fitted on the track. The second mounting plate and the sliding block are fixedly connected. A plurality of copper needle contacts 5 are fixedly mounted on the second mounting plate. The number of copper needle contacts is equal to that of fixed contacts and corresponds to each other up and down. When the up-and-down driving mechanism drives the second mounting plate to move downward, the copper needle contacts contact the fixed contacts. The copper needle contacts and the fixed contacts are respectively connected to the tester. The test can be an inductance tester or a volt-ampere tester.

[0021] The material blocking cylinder, lifting cylinder and linear module are all connected to the controller for control.

[0022] The working process of this testing machine is as follows: in the initial state, the lifting cylinder is in the raised position, the slider of the linear module is at the front, the cylinder rod of the material blocking cylinder extends out to block the slot track, and the sorting conveyor belt sends the magnetic cores on it into the slot track. The magnetic cores move forward and backward one after another under the thrust generated by the sorting conveyor belt. When the second material detection switch detects the magnetic core, the sorting conveyor belt stops, and the first material switch also detects the magnetic core at the same time. This is the lifting cylinder driving the second mounting plate downward, and the copper needle contact passes through the middle hole of the magnetic core and contacts with the fixed contact. The tester can obtain relevant test data, the material blocking cylinder retracts, and the linear module drives the first mounting plate to move backward. Since the copper needle is located in the middle hole of the magnetic core, the copper needle moves back and forth and drives all the magnetic cores to move backward. After moving into place, the lifting cylinder resets, the linear module resets, and the material blocking cylinder resets to test the next batch of magnetic cores.

[0023] After describing the implementation mode of the utility model in detail, people familiar with the technology can clearly understand that various changes and modifications can be made without departing from the scope and spirit of the above-mentioned patent application. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the utility model are within the scope of the technical solution of the utility model, and the utility model is not limited to the implementation mode of the examples given in the specification.
