Description

Technical Field

[0001] The utility model relates to the technical field of inductor production, in particular to a chip inductor centering positioning device. Background Art

[0002] Inductor, also known as choke, reactor, dynamic reactor, is a component that can convert electrical energy into magnetic energy and store it. The structure of the inductor is similar to that of a transformer, but it has only one winding. The inductor has a certain inductance, it only hinders the change of current, and the inductor is widely used in various fields such as machinery and electricity. The inductor is generally composed of a skeleton, a coil winding, a shielding cover, a packaging material, a magnetic core or an iron core, etc. Common inductors include magnetic ring inductors, color ring inductors, chip inductors, one-piece molded inductors, etc. Different inductors have different processing requirements. After the inductor is processed, the inductor needs to be tested, including electrical performance testing, appearance testing, etc. Taking chip inductors as an example, during the electrical testing of chip inductors, it is necessary to accurately bring the test head into contact with the contacts of the chip inductor. In order to ensure accuracy, the traditional practice is to place the inductor in a positioning fixture before testing. After the test, the inductor is taken out and a new one is placed. This method is time-consuming and slow. At the same time, with the continuous miniaturization of electronic products, many tiny inductors have appeared. It is more inconvenient to use fixtures to position such tiny products. Utility Model Content

[0021] In order to facilitate those skilled in the art to understand the present invention, the present invention will be further described in detail below in conjunction with specific embodiments and drawings.

[0022] Reference Figures 1 to 3The present embodiment provides a device for centering and positioning a chip inductor, the device comprising a turntable transport mechanism for transporting the inductor, and a positioning mechanism for positioning the inductor, the positioning mechanism comprising a first horizontal adjustment module, a second horizontal adjustment module connected to the first horizontal adjustment module, a fixing frame arranged on the second horizontal adjustment module, a positioning seat arranged on the fixing frame, a first positioning component, a second positioning component, a third positioning component, and a fourth positioning component arranged on the positioning seat, and a driving component arranged on the fixing frame for driving the first positioning component, the second positioning component, the third positioning component, and the fourth positioning component to move. Specifically, the first positioning component and the third positioning component can be driven by the driving component to move closer to or farther from each other, and the second positioning component and the fourth positioning component can be driven by the driving component to move closer to or farther from each other, so that the first positioning component, the second positioning component, the third positioning component, and the fourth positioning component can approach a center point, which is the position where the inductor is placed (in this embodiment, the center point can correspond to the center position of the positioning seat). After the four positioning components approach the inductor, they contact the inductor. Since the four positioning components move synchronously, they push the inductor to move to the center position, thereby achieving center positioning (the chip inductor is a rectangle, and the four positioning components correspond to the four sides of the chip inductor).

[0023] The first positioning assembly, the second positioning assembly, the third positioning assembly, and the fourth positioning assembly on the positioning seat all include a sliding block connected to the positioning seat, a fixed seat connected to the sliding block, a connecting seat arranged on the fixed seat, and a positioning piece arranged on the connecting seat. A positioning bracket corresponding to the fixed seat is arranged on one side of the positioning seat, an elastic piece is connected between the positioning bracket and the fixed seat, and a slide rail matching the sliding block is arranged on the positioning seat. The connecting seat is provided with a connecting groove for connecting the positioning piece. The elastic piece can drive the sliding block to move toward the center point. In this embodiment, the elastic piece is a coil spring, and the sliding block moves toward the center point under the action of the elastic force.

[0024] The driving assembly includes a driving motor connected to the fixing frame, a transmission cam connected to the output end of the driving motor, and a driving roller matched with the transmission cam connected to the fixing seat. Specifically, the transmission cam is a square cam with four rounded corners. When the transmission roller contacts the rounded corners, the elastic member is compressed, and the two relative positioning members are in a diagonal position with the farthest distance, that is, the two relative positioning members are far away from each other in this state. When the transmission roller contacts the straight edge of the transmission cam, the elastic member is reset, and the distance between the two relative positioning members is the smallest. In this state, the two positioning members approach each other toward the center point, and the positioning member contacts the inductor to center the inductor.

[0025] The positioning seat is provided with a connecting arm, which extends downward to a position corresponding to the cam, and the transmission roller is connected to the bottom end of the connecting arm.

[0026] The first horizontal adjustment module and the second horizontal adjustment module both include an adjustment seat, a movable seat connected to the adjustment seat, a first adjustment bracket arranged on one side of the adjustment seat, a second adjustment bracket arranged on the movable seat and corresponding to the first adjustment bracket, and an adjustment member arranged on the second adjustment bracket.

[0027] The adjusting member is a differential head, and the end of the differential head is in contact with the first adjusting bracket. When the differential head is rotated, the end extends or retracts, so that the relative position of the movable seat and the adjusting seat can be accurately adjusted, and finally the purpose of adjusting the position of the fixed frame is achieved, so that the first positioning component, the second positioning component, the third positioning component, and the fourth positioning component can correspond to the positioned inductor position.

[0028] The turntable transport mechanism includes a rotating disk, a plurality of transport brackets arranged on the rotating disk, and a suction nozzle connected to the transport bracket. The suction nozzle adsorbs the chip inductor and moves driven by the rotating disk. The rotating disk rotates the same angle each time. When the inductor adsorbed by one of the suction nozzles reaches the middle of the positioning parts of the first positioning component, the second positioning component, the third positioning component, and the fourth positioning component, the driving component is started, and the four positioning components approach the chip inductor at the same time. The four positioning parts contact the four sides of the chip inductor respectively, push the chip inductor to move, and center the chip inductor. The chip inductor is tightly adsorbed by the suction nozzle, and the chip inductor will not fall off during the positioning process. After the positioning is completed, each positioning component is reset, and the rotating disk rotates the same angle again, and the next inductor reaches the current position for positioning. During specific work, the turntable transport mechanism can be docked with the test equipment. Taking electrical testing as an example, after the positioned chip inductor is moved to the test equipment, the connector of the test equipment can accurately contact the contacts of the chip inductor and become conductive.
