Description

Technical Field

[0001] The present invention relates to the technical field of inductors, and particularly to a positioning tooling for high-frequency inductors. Background Art

[0002] An inductor is a passive electronic component used to store and release electromagnetic energy, which is widely used in electronic circuits. Its core principle is based on Faraday's law of electromagnetic induction. By changing the current in the coil, a magnetic field is generated, and then energy is stored. The main characteristic of an inductor is to impede the change of current, and it is commonly used in scenarios such as filtering, oscillation, energy storage, and signal processing.

[0003] The patent application with the application number CN202220667139.1 discloses a positioning tooling for inductors, including: a bottom plate; a first positioning member, with multiple columns of the first positioning members arranged along the length direction of the bottom plate; a second positioning member, with each column of the second positioning members respectively located between two adjacent columns of the first positioning members; wherein, the distance between two adjacent columns of the first positioning members can be adjusted.

[0004] In summary, during the installation process of high-frequency inductors, if the pins of the high-frequency inductor do not accurately align with the corresponding positions on the circuit board, it may lead to installation deviation, which will further interfere with the normal transmission of current between the inductor and the circuit board, affecting the performance of the circuit.

For example, it can be a fixed connection, a detachable connection, or an integral body; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] Example 1: Refer to Figures 1-8, the present invention provides a technical solution: a high-frequency inductor positioning tooling, including a support mechanism 1. The support mechanism 1 includes a support frame 101. A support foot 102 is fixedly connected to the bottom outer wall of the support frame 101. A first motor 103 is fixedly connected to the outer wall of the support frame 101. A first rotating shaft 104 is fixedly connected to the output end of the first motor 103. A first sliding frame 105 is arranged at the output end of the first motor 103. The first sliding frame 105 is movably sleeved on the outer surface of the first rotating shaft 104. A second motor 106 is fixedly connected to the outer wall of the first sliding frame 105. A second rotating shaft 107 is fixedly connected to the output end of the second motor 106, including:

[0034] An adjustment mechanism 2, including a second sliding frame 201 arranged at the output end of the second motor 106. A fixed ring 202 is fixedly connected to the bottom outer wall of the second sliding frame 201. A sliding groove 203 is formed on the outer surface of one side of the fixed ring 202 away from the second sliding frame 201. A distance control component 204 is arranged at the bottom of the fixed ring 202. The distance control component 204 includes a first rotating frame 2041 slidably connected to the fixed ring 202. A third motor 2042 is fixedly connected to the bottom outer wall of the first rotating frame 2041. The output end of the third motor 2042 penetrates through the first rotating frame 2041 and is fixedly connected to a driving wheel 2043. The driving wheel 2043 is rotatably connected to the inner wall of the sliding groove 203. A first hydraulic rod 2044 is fixedly connected to the inner wall of the second sliding frame 201. The output end of the first hydraulic rod 2044 is fixedly connected to a fixed frame 2045. When positioning and installing a high-frequency inductor, first place the circuit board on which the inductor needs to be installed on the support frame 101, and then fix the inductor through the clamping component 206. The first motor 103 drives the first sliding frame 105 to move to an appropriate position through the first rotating shaft 104. Subsequently, the second motor 106 drives the second sliding frame 201 through the second rotating shaft 107 to accurately align the high-frequency inductor with the installation position. The third motor 2042 makes the first rotating frame 2041 slide along the outer surface of the fixed ring 202 through the driving wheel 2043, driving the inductor to adjust the angle, so as to accurately position and install the inductor from multiple angles.

[0035] A fixed shaft 2046 is fixedly connected to the top of the fixed frame 2045. One end of the fixed shaft 2046 away from the fixed frame 2045 penetrates through the second sliding frame 201 and is fixedly connected to a first spring 2047. One end of the first spring 2047 close to the fixed frame 2045 is fixedly connected to the second sliding frame 201. When the first hydraulic rod 2044 pushes the fixed frame 2045 towards the circuit board side, the fixed frame 2045 pulls the first spring 2047 through the fixed shaft 2046, thereby improving the stability of the fixed frame 2045 during the moving process.

[0036] The inner wall of the fixing frame 2045 is fixedly connected with a dual-axis motor 2048. The output end of the dual-axis motor 2048 is fixedly connected with a second rotating frame 2049. The inner wall of the second rotating frame 2049 is fixedly connected with a second hydraulic rod 20410. The output end of the second hydraulic rod 20410 is provided with an auxiliary component 205. During the process of the first hydraulic rod 2044 pushing the fixing frame 2045 towards the circuit board, the dual-axis motor 2048 drives the second hydraulic rod 20410 to adjust the angle through the second rotating frame 2049, so that when the high-frequency inductor needs to be welded at a specific inclination angle, it can achieve the corresponding angle deflection, further improving the welding precision of the solder legs.

[0037] The auxiliary component 205 includes a first connecting frame 2051 fixedly connected with the second hydraulic rod 20410. The inner wall of the first connecting frame 2051 is rotatably connected with a first rotating rod 2052 through a rotating shaft. The inner wall of the end of the first rotating rod 2052 away from the first connecting frame 2051 is rotatably connected with a second rotating rod 2053 through a rotating shaft. The end of the second rotating rod 2053 away from the first rotating rod 2052 is fixedly connected with the second rotating frame 2049. The inner wall of the first connecting frame 2051 is fixedly connected with a first telescopic rod 2054. The output end of the first telescopic rod 2054 is provided with a clamping component 206. When it is necessary to clamp and fix high-frequency inductors with different diameters, the second hydraulic rod 20410 adjusts the distance between the force-bearing plates 2063 by pushing the first connecting frame 2051, thereby stably clamping inductors of different sizes. During the sliding process of the first connecting frame 2051, its inner wall drives the second rotating rod 2053 to move through the first rotating rod 2052, and the stability of the sliding of the first connecting frame 2051 is enhanced through the first rotating rod 2052 and the second rotating rod 2053.

[0038] The clamping component 206 includes a second connecting frame 2061 fixedly connected with the first telescopic rod 2054. The inner wall of the second connecting frame 2061 is fixedly connected with a second telescopic rod 2062. The output end of the second telescopic rod 2062 penetrates through the second connecting frame 2061 and is fixedly connected with a force-bearing plate 2063. The second telescopic rod 2062 clamps the high-frequency inductor through the force-bearing plate 2063. When it is necessary to clamp and fix the high-frequency inductor, after the second hydraulic rod 20410 first drives the first connecting frame 2051 to a predetermined position, the second telescopic rod 2062 pushes the force-bearing plate 2063 to move towards the inductor, and applies pressure to the outer surface of the inductor through the force-bearing plate 2063, thereby achieving stable clamping and fixing.

[0039] The inner wall of the second connecting frame 2061 is rotatably connected to a first auxiliary rod 2064 through a rotating shaft. One end of the first auxiliary rod 2064 away from the second connecting frame 2061 is rotatably connected to a clamping plate 2065 through a rotating shaft. The inner wall of the first auxiliary rod 2064 is rotatably connected to a second auxiliary rod 2067 through a rotating shaft. One end of the second auxiliary rod 2067 away from the first auxiliary rod 2064 is rotatably connected to a force-bearing plate 2063. The force-bearing plate 2063 deflects the first auxiliary rod 2064 through the second auxiliary rod 2067. On the outer wall of the side of the clamping plate 2065 close to the first auxiliary rod 2064, a second spring 2066 is fixedly connected. One end of the second spring 2066 away from the clamping plate 2065 is fixedly connected to the first auxiliary rod 2064. The second spring 2066 is used for the reset of the clamping plate 2065. When the second telescopic rod 2062 applies a force to the force-bearing plate 2063 according to the shape of the high-frequency inductor, the force-bearing plate 2063 uses the second auxiliary rod 2067 to cause the first auxiliary rod 2064 to tilt towards the inductor. The clamping plate 2065 rotatably connected to the first auxiliary rod 2064 then firmly clamps the outer shell of the inductor. The second spring 2066 adjusts the rotation angle of the clamping plate 2065, so that the clamping plate 2065 can better contact the outer surface of the high-frequency inductor.

[0040] On the outer wall of the side of the force-bearing plate 2063 close to the second telescopic rod 2062, an auxiliary motor 2068 is fixedly connected. The output end of the auxiliary motor 2068 is fixedly connected to an arc-shaped rod 2069. On the inner wall of the side of the arc-shaped rod 2069 away from the auxiliary motor 2068, a third telescopic rod 20610 is fixedly connected. The output end of the third telescopic rod 20610 is fixedly connected to an adjustment block 20611. The auxiliary motor 2068 deflects the third telescopic rod 20610 through the arc-shaped rod 2069. When welding the pins of the high-frequency inductor, the auxiliary motor 2068 drives the adjustment block 20611 to flip towards the pin side through the arc-shaped rod 2069. At the same time, the third telescopic rod 20610 finely adjusts the position of the pin, thereby improving the precision of welding and installation.
