Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of magnetic resonance radio frequency coils, and particularly relates to a soldering iron head for debugging a magnetic resonance radio frequency coil. Background Art
[0002] Magnetic resonance imaging is an advanced non-destructive imaging technology for the human body, and is widely used in the medical imaging diagnosis of diseases in various parts of the human body. The magnetic resonance radio frequency coil is an important component of the magnetic resonance imaging system, and its performance directly determines the quality of the magnetic resonance image.
[0003] The magnetic resonance radio frequency coil is used to transmit radio frequency pulses and receive magnetic resonance signals, and is the core component of the magnetic resonance imaging system. As the front end of the signal receiving chain, the radio frequency receiving coil is crucial for the quality of imaging. Therefore, in the process of research and development and production, it is necessary to finely debug the radio frequency coil. Except for the simplest single-channel radio frequency receiving coil that has long been out of use, all radio frequency receiving coils contain multiple channels. Currently, the more mainstream radio frequency receiving coils are 32-channel or 64-channel. Since the magnetic resonance radio frequency coil has very strict requirements for the resonance frequency, the frequency of each channel must be adjusted to a very accurate value, which requires a lot of manpower and time. The calculation formula for the frequency f of the magnetic resonance radio frequency coil channel is In the formula, L is the inductance value of the channel, and C is the capacitance value of the channel. Since it is troublesome to change the inductance, generally, the method of changing the capacitance is used to adjust the frequency of the channel. Although both L and C are obtained through calculation and have corresponding values, because any product has a certain tolerance, there is a certain deviation in the capacitance values of the same batch of capacitors with the same specifications. This deviation is very small, but for magnetic resonance imaging, it may cause the magnetic resonance image to be unclear. Therefore, it is necessary to adjust the capacitance value as much as possible to make the frequency of the channel meet the required requirements. During the actual debugging process, it is necessary to continuously replace the capacitor and test the resonance frequency of the channel until the requirements are met. In this process, it is necessary to continuously solder a capacitor on the corresponding pad of the channel. If the requirements are not met, it is removed and another capacitor is soldered on. It is very convenient to solder the capacitor. First, solder the welding surface at one end of the capacitor, and then solder the other end surface after soldering. However, it is more troublesome to solder the capacitor off. It is necessary to first place the soldering iron at one end of the capacitor to melt the solder at the welding point, and then place the soldering iron at the solder at the other end of the capacitor to melt it. During this process, the solder that has melted at the beginning end may have partially solidified and cannot be removed. Therefore, it is necessary to quickly switch the soldering iron head of the soldering iron at both ends of the capacitor, and the capacitor can be removed only when the solder at both ends has melted. Summary of the Invention

[0005] To achieve the above object, a soldering iron tip for debugging a magnetic resonance radio frequency coil is designed, including a soldering iron tip body, characterized in that: the soldering iron tip body is of a rectangular structure, the head of the soldering iron tip body is of an open structure, and the open structure is composed of a first front end and a second front end, and the inner sides of the first front end and the second front end are planes.

[0011] Figure 2 It is a schematic diagram of the usage state of the structure of the present utility model.
[0012] Figure 3 It is a schematic structural diagram of another solution of the present utility model.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0014] The following further describes the present utility model with reference to the drawings.
[0015] As Figure 1 shown, the soldering iron tip body 1 is of a rectangular structure, the head of the soldering iron tip body 1 is of an open structure, and the open structure is composed of a first front end 2 and a second front end 3, and the inner sides of the first front end 2 and the second front end 3 are planes.
[0016] The distance between the first front end 2 and the second front end 3 is the width of a standard electronic component.
[0017] One end of the first front end 2 and the second front end 3 is connected to the soldering iron head body 1, and the other ends of the first front end 2 and the second front end 3 are arranged separately; and the middle parts of the first front end 2 and the second front end 3 are connected by a connecting piece.
[0018] The connecting piece is a tightening screw.
[0019] The two parts at the front end of the soldering iron head body 1 of the present utility model, namely the first front end 2 and the second front end 3, the distance between the first front end 2 and the second front end 3 is the width of the electronic component to be soldered off. Since general electronic components have unified specifications, and during the debugging process of the magnetic resonance radio frequency coil, the vast majority are welding and replacing capacitors, so the distance between the first front end 2 and the second front end 3 can be determined as the width of the capacitor. In this way, when welding the capacitor, both ends of the capacitor can be heated simultaneously, and the solder at both ends will melt at the same time, which is very convenient to solder on or solder off.
[0020] As Figure 2 shown, the front end of the soldering iron head body 1 is separated into two parts, the first front end 2 and the second front end 3, and the distance between the first front end 2 and the second front end 3 is slightly larger than the square capacitor 4. When in use, place the square capacitor 4 on the first solder pad 6 and the second solder pad 7 to be welded, then apply solder to both the first front end 2 and the second front end 3, place them on both sides of the square capacitor 4, and when waiting for the melted solder to be connected to the solder pads, remove the soldering iron head body 1, wait for a moment, and after the solder solidifies, the square capacitor 4 is welded to the first solder pad 6 and the second solder pad 7.
[0021] When it is necessary to solder off the square capacitor 4, place the first front end 2 and the second front end 3 of the soldering iron head body 1 on both sides of the square capacitor 4, and after the solder on both sides melts, use tweezers to clamp the square capacitor 4 and take it off.
[0022] The above Figure 1 , Figure 2 shown structure of the soldering iron head body 1, although it solves the problem that the electronic component is not convenient to solder off during the debugging process of the magnetic resonance radio frequency coil, the distance between the two separated parts of the soldering iron head body 1 is fixed, and it can only be used for welding capacitors with the same mechanical size. Different components (such as square capacitors and inductors) have different sizes, or the same components with different mechanical specifications cannot be welded with the same soldering iron head.
[0023] As Figure 3As shown in the figure, a hole is drilled and tapped between two separated parts (i.e., the first front end 2 and the second front end 3) at the front end of the soldering iron head body 1 to machine screw threads, and a screw 8 with a suitable size is screwed in. In this way, during use, by simply loosening or tightening the screw 8, the distance at the very front end of the soldering iron head can be changed, so that it can be used to weld electronic components of different sizes.
[0024] In summary, by using the soldering iron head dedicated to debugging the magnetic resonance radio frequency coil designed with the present utility model, components such as capacitors, inductors or resistors can be conveniently welded into or soldered off from the channels during the debugging process.
