Description

Technical Field

[0001] The present invention relates to the technical field of workpiece detection, and more specifically, to a spiral coil detection device and method. Background Art

[0002] In the ion implantation process, the beam current needs to be accelerated to a certain energy level in the radio frequency section to successfully complete ion implantation, which is an important standard for the maturity of ion implantation technology. To ensure that the beam current is accelerated to the required energy level, it needs to be continuously accelerated in the acceleration section. The radio frequency bucket is an important component that plays an accelerating role. Multiple radio frequency buckets are arranged in sequence in the beam channel, which can play a role of continuous acceleration. The principle of the radio frequency bucket is an LCR oscillation circuit, and ions will be accelerated when passing through the channel where they are located.

[0003] The spiral coil is an important component for radio frequency acceleration in the semiconductor ion implantation process. The core principle of radio frequency acceleration is that the LCR oscillation circuit accelerates the ions passing through the channel. In the oscillation circuit, the spiral coil can be regarded as an inductor L, providing inductance for the acceleration bucket, so the spiral coil can also be called an inductance coil.

[0004] That is, the spiral coil is an important component that provides inductance L, and its shape directly determines the provided inductance value. The processing technologies of inductance coils vary among different manufacturers, and may involve process steps such as welding, bending, shaping, electroplating, annealing, etc. Due to the high processing difficulty of its spiral shape and the difficulty in controlling key dimensions, the finished product may exhibit phenomena such as skewing, shortening, elongation, swelling, etc.

[0005] In the prior art, there has been no relevant report on a precision tooling that can directly detect spiral coils.

[0006] Therefore, it is necessary to provide a spiral coil detection tool and method for detecting the key dimensions of spiral coils. Summary of the Invention

[0007] In view of this, one of the purposes of the present invention is to provide a spiral coil detection device. The detection device provided by the present invention can detect multiple key dimensions of the spiral coil, and is easy to operate and has high detection efficiency.

A slide table is installed on the lead screw, and the front and rear sides of the slide table are respectively slidably connected to the corresponding slide rods. One end of the lead screw passes through the outer limit plate and is connected to an adjustment handle. The upper end surface of the slide table is detachably connected to the high support pillar.

[0016] Rotating the adjustment handle can drive the slide table to move horizontally along the length direction of the slide rod, and further drive the high support pillar to move towards or away from the low support pillar.

[0018] Further, a first threaded hole is opened in the first groove, and a second threaded hole is opened in the second groove.

[0019] Further, the device further includes a spiral pipe clamp for clamping the coil body. There are two sets of the spiral pipe clamps.

[0050] In the following description, many specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific implementations disclosed below.

[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0052] The structure provided by the present invention will be explained and described in detail below with reference to the accompanying drawings of the specification.

[0053] Reference Figures 1 to 6 As shown, this embodiment specifically provides a spiral coil detection device for detecting the spiral coil 100. The spiral coil 100 in this embodiment is a component in ion implantation, which includes a coil body 101, a first end 102 formed on one side of the coil body 101, and a second end 103 formed on the other side of the coil body 101. Circular rings 104 are provided on both the first end 102 and the second end 103, and the circular rings 104 at both ends are used for installation and sealing purposes;

[0054] Specifically, the detection device includes a bottom plate 1. On one side of the top of the bottom plate 1, a low support column 2 is provided (the low support column 2 can be fixedly connected to the bottom plate through threads and pins), and a horizontal adjustment mechanism 3 is installed on the other side. A high support column 4 is detachably installed on the horizontal adjustment mechanism 3 (ears are formed on both sides of the bottom of the high support column 4, and the ears are detachably connected to the horizontal adjustment mechanism 3 through threads and bolts for easy replacement). Adjusting the horizontal adjustment mechanism 3 can drive the high support column 4 to move horizontally towards or away from the low support column 2;

[0055] A first U-shaped groove 2a for placing and supporting the first end 102 is provided at the top of the low support column 2. A first groove 2b adapted to the circular ring 104 on the first end 102 is also opened on the inner side surface of the upper end of the low support column 2. The first U-shaped groove 2a and the first groove 2b are interconnected. The first groove 2b is in a semi-circular structure, and the circular ring 104 can just be placed in the first groove 2b. The first end 102 of the spiral coil 100 extends to the first U-shaped groove 2a after passing through the first groove 2b, is supported in the first U-shaped groove 2a, and the end extends outside the first U-shaped groove 2a; A second U-shaped groove 4a for placing the second end 103 is provided at the top of the high support column 4. A second groove 4b adapted to the circular ring 104 on the second end 103 is also opened on the inner side surface of the upper end of the high support column 4. The second U-shaped groove 4a and the second groove 4b are interconnected; The second groove 4b is also in a semi-circular structure, and the circular ring 104 on the second end can also just be placed in the second groove 4b. The second end 103 of the spiral coil 100 extends to the second U-shaped groove 4a after passing through the second groove 4b, is supported in the second U-shaped groove 4a, and the end extends outside the second U-shaped groove 4a;

[0056] A limit support column 6 is installed on the bottom plate 1 on the side close to the low support column 2, and a stop block 7 capable of abutting against the coil body 101 is installed on the inner side surface of the limit support column 6; It can be understood that the contact position between the stop block 7 and the coil body 101 is exactly the starting rotation position of the coil body 101;

[0057] A support block 8 is also provided on the bottom plate 1 between the low support column 2 and the high support column 4, and a support pad 9 for supporting the bottom of the coil body 101 is installed on the support block 8; The material of the support pad 9 can be selected as plastic, which will not damage the surface of the spiral coil 100.

[0058] It can be understood that when designing the detection device provided in this embodiment, it can be set according to the spiral coil 100 of the standard part. That is, the positions between the low strut 2 and the high strut 4 can be initially determined according to the distance between the two ends of the standard part spiral coil 100. At the same time, by combining the heights of the first end and the second end, the opening depths of the corresponding U-shaped grooves in the low strut 2 and the high strut 4 and the heights of the low strut 2 and the high strut 4 can be determined. At the same time, the position and height of the limit strut 6 can be determined according to the starting position of the spiral coil 100. Based on this, a detection device for the spiral coil 100 of the standard part can be obtained, and then it can be used to detect the relevant dimensions of other spiral coils to be detected to determine whether there are differences between the spiral coils to be detected and the standard part (such as whether it can fit with the stopper 7, whether it can be just stuck in the first U-shaped groove and the second U-shaped groove, etc.), so as to judge whether the spiral coil to be detected is a qualified product.

[0059] Continue to refer to Figure 1 As shown, a square groove 1a is provided on the bottom plate 1 on the side where the high strut 4 is installed, which is used to install the horizontal adjustment mechanism 3, which can play a role in weight reduction. At the same time, installing the horizontal adjustment mechanism 3 in the square groove 1a can also have a certain limiting effect.

[0060] Specifically, the horizontal adjustment mechanism 3 includes a base 3a installed in the square groove 1a. On the upper left and right sides of the base 3a, limit plates 3b are respectively provided. Between the two limit plates 3b, a lead screw 3c and a slide bar 3d are provided. There are two slide bars 3d, which are respectively located in front of and behind the lead screw 3c. A slide table 3e is installed on the lead screw 3c, and the front and rear sides of the slide table 3d are respectively slidably connected to the corresponding slide bars 3d. One end of the lead screw 3c passes through the outer limit plate 3b and is connected with an adjustment handle 3f. The upper end surface of the slide table 3e is detachably connected to the high strut 4.

[0061] Rotating the adjustment handle 3f can drive the slide table 3e to move horizontally along the length direction of the slide bar 3d, and then drive the high strut 4 to move towards or away from the low strut 2.

[0062] The horizontal adjustment mechanism 3 provided in this embodiment can achieve precise adjustment of the high strut 4 and improve the detection accuracy.

[0063] Furthermore, as shown in Figure 5 A pointer 10 is also provided on the slide table 3e, and a scale 11 is provided on the bottom plate 1 along the moving direction of the slide table 3e. The scale 11 can also be fixed on the bottom plate 1 through threads and pins. The scale of the pointer 10 is 0 in the default position. By setting the pointer 10 and the scale 11, the size offset of the spiral coil 100 to be detected can be observed more intuitively.

[0064] In some embodiments, a first threaded hole (not shown in the figure) is provided in the first groove 2b, and a second threaded hole (not shown in the figure) is provided in the second groove 4b; when needed, the ring 104 at the first end 102 can be fixed in the first groove 2b through the first threaded hole to increase stability; or the ring 104 at the second end 103 can be fixed in the second groove 4b. It can be understood that when detecting the coil size, only the ring at the first end 102 needs to be fixed; after the detection is completed, when the spiral coil 100 needs to be placed on the detection device, the rings 104 at both ends can be fixed to the corresponding grooves at the same time to avoid falling off and scratching.

[0065] Combined with Figure 4 As shown, the detection device further includes a spiral pipe clamp 12 for clamping the coil body 101. There are two sets of spiral pipe clamps 12, which are respectively used for clamping on the front and back sides of the coil. Each set of spiral pipe clamps 12 is composed of two clamping plates 12a connected by screws. Semi-circular clamping grooves 12b adapted to the coil body 101 are correspondingly formed on both clamping plates 12a; by providing the spiral pipe clamp 12, the detection of the turn pitch and the wire tube diameter of the spiral coil can be realized.

[0066] Referring to Figure 6 As shown, the detection device further includes a side deviation support column 13 for replacing the high support column 4. A third U-shaped groove 13a for placing the second end 103 is provided at the top of the side deviation support column 13. A circular scale 13b and a linear scale 13c are provided on the inner side surface of the upper end of the side deviation support column 13. A step portion 13d is formed on the inner side surface of the upper end of the side deviation support column 13 below the circular scale 13b and the linear scale 13c.

[0067] The side deviation support column 13 is used to replace the high support column 4. It can be understood that the structure at the bottom of the side deviation support column 13 is exactly the same as that of the high support column 4, that is, ears can also be formed at the bottom for detachable connection with the sliding table 3e; the main difference lies in the upper end of the side deviation support column 13. When the center of the spiral coil to be detected is offset too much and the ring 104 at the second end 103 is difficult to be clamped in the second groove 4b of the high support column 4, the high support column 4 can be removed and the side deviation support column 13 can be installed. At this time, the step portion 13 on the side deviation support column 13 can support the ring 104 at the second end 103, and the center offset of the spiral coil 100 to be detected can be measured through the circular scale 13b and the linear scale 13c.

[0068] In some embodiments, weight reduction holes 1b are further provided on both sides of the support block 8 in the middle of the bottom plate 1; by providing the weight reduction holes 1b, the overall weight of the detection device can be reduced, which is convenient for handling and transferring. In some preferred embodiments, the weight reduction holes 1b can be in a honeycomb-shaped hollow, which can improve the bending stiffness of the bottom plate 1 while reducing the weight and ensure the structural strength of the bottom plate 1.

[0069] Continuing to refer toFigure 2 and Figure 3 As shown in Figure 3 , a through first long slot 2c is provided on the lower side of the low support column 2; a through second long slot 4c is also provided on the lower side of the high support column 4; a pulling handle 5 is further provided on the bottom plate 1 on one side close to the high support column 4; the settings of the first long slot 2c and the second long slot 4c can also reduce the overall weight of the device and can also be used as a handle at the same time.

[0070] This embodiment also provides a detection method for a spiral coil, including the following steps:

[0071] 1) Device assembly: Install the low support column 2 and the limit support column 6 on the left side of the bottom plate 1, install the support block 8 and the support pad 9 in the middle of the bottom plate, and install the horizontal adjustment mechanism 3, the high support column 4, the scale 11 and the pointer 10 on the right side of the bottom plate 1;

[0072] 2) In the illustrated embodiment, with the side where the high support column 4 is located as the right side and the side where the low support column 2 is located as the left side, place the detection device horizontally. Adjust the high support column 4 to move away from the low support column 2, that is, move to the right, to deviate from the 0 scale (to facilitate placing the spiral coil to be detected). Place the first end 102 of the spiral coil 100 in the first U-shaped groove 2a on the low support column 2, and the ring 104 on the first end 102 is clamped in the first groove 2b. Place the second end 103 of the spiral coil 100 in the second U-shaped groove 4a on the high support column 4, and the ring 104 of the second end 103 is placed in the second groove 4b;

[0073] 3) Use screws to connect the ring 104 on the first end 102 with the first groove 2b, and detect the distance between the outer side surface of the ring 104 on the second end 103 and the second groove 4b. If there is a gap, adjust the horizontal adjustment mechanism to drive the high support column 4 to move towards the low support column 2, that is, move to the left, until the second groove 4b fits with the outer side surface of the ring 104 of the second end;

[0074] 4) Observe the scale value pointed to by the pointer 10. If the scale value points to the 0 scale (i.e., the initial value), continue to step 5), otherwise, it is unqualified;

[0075] It can be understood that if the second groove 4b fits with the outer side surface of the ring 104 of the second end, and at this time the pointer just points to the scale 0, it can be judged as initially qualified, otherwise, it is unqualified and needs to be repaired and adjusted;

[0076] Further, after being initially qualified, the following steps are also included:

[0077] 5) Adjust the horizontal adjustment mechanism 3 to the relaxed position, that is, also adjust it to the right to deviate from the 0 scale. Install the hose clamp 12 on the spiral coil 100, and repeat steps 2)-3). Observe whether the scale value pointed to by the pointer is the same as that pointed to in step 4). That is, when it also points to the 0 scale, it is finally determined that the spiral coil is a qualified product; otherwise, it is also an unqualified product and needs to be repaired and adjusted.

[0078] The spiral coil that meets this spiral coil detection device meets the design and usage requirements.

[0079] Optionally, when the center of the spiral coil 100 to be detected is offset too much, the following steps are included:

[0080] Replace the high support 4 with the side offset support 13, and install the side offset support 13 on the horizontal adjustment mechanism 3;

[0081] Adjust the side offset support 13 to the right through the horizontal adjustment mechanism 3 to deviate from the 0 scale. Place the first end 102 of the spiral coil 100 in the first U-shaped groove 2a on the low support 2, and the ring 104 on the first end 102 is clamped in the first groove 2b. Place the second end 103 of the spiral coil 100 in the third U-shaped groove 13a on the side offset support 13, and the ring 104 of the second end 103 is placed on the step portion 13d;

[0082] Use a screw to connect the ring 104 on the first end 102 with the first groove 2b, and detect the distance between the outer side surface of the ring 104 on the second end 103 and the inner end surface of the side offset support 13. If there is a gap, adjust the horizontal adjustment mechanism 3 to drive the side offset support 13 to move towards the low support 2 until the inner end surface of the side offset support 13 is in mutual contact with the outer side surface of the ring 104 on the second end 103; determine the center offset of the spiral coil to be detected through the circular scale 13b and the linear scale 13c on the side offset support 13.

[0083] Of course, when it is found that the side offset support 13 needs to be used for detection, the spiral coil to be detected is already an unqualified product and also needs to be repaired and adjusted. At this time, the side offset support 13 is mainly used to record its specific offset amount and provide relevant data for adjustment.

[0085] (1) It can detect multiple key dimensions of the spiral coil, such as the starting rotation position, turn spacing, wire tube diameter, distance between both end faces, and offset degree;
