Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of workpiece detection, and more particularly to a spiral coil detection device and method. BACKGROUND

[0002] In ion implantation process, beam current needs to be accelerated to a certain energy level by radio frequency section, so as to successfully complete ion implantation, which is an important standard for maturity of ion implantation technology. In order 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 for acceleration. A plurality of radio frequency buckets are arranged in sequence in the beam current channel, which can continuously accelerate. The principle of the radio frequency bucket is LCR oscillation circuit, and the ions passing through the channel will be accelerated.

[0003] The spiral coil is an important component of radio frequency acceleration in semiconductor ion implantation process, and 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, which provides inductance, so the spiral coil can also be called an inductor coil.

[0004] That is, the spiral coil is an important component for providing inductance L, and its shape directly determines the inductance value. The processing technology of the inductor coil is different for different manufacturers, which may involve welding, bending, solidification, electroplating, annealing and other process steps. Due to the high difficulty in processing the spiral shape, it is difficult to control the key dimensions, which may cause the finished product to be skewed, shortened, too long, expanded and other phenomena.

[0005] In the prior art, there is no related report on a spiral coil detection tool that can directly detect the spiral coil.

[0050] Numerous specific details are set forth in the following description to provide a full understanding of the invention. However, the invention can be practiced in many other ways different from those described herein, and similar modifications can be made by those skilled in the art without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

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

[0053] refer to Figures 1 to 6 As shown, this embodiment specifically provides a spiral coil detection device for detecting a 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. Both the first end 102 and the second end 103 are provided with a ring 104, and the rings 104 at both ends are used for installation and sealing.

[0054] Specifically, the detection device includes a base plate 1. A low support column 2 is provided on one side of the top of the base plate 1 (the low support column 2 can be fixed to the base plate by threads or 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 (the high support column 4 has lugs on both sides of its bottom, and the lugs are detachably connected to the horizontal adjustment mechanism 3 by threads or 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] The top of the low support column 2 is provided with a first U-shaped groove 2a for placing and supporting the first end 102. The inner side of the upper end of the low support column 2 is also provided with a first groove 2b that corresponds to the ring 104 on the first end 102. The first U-shaped groove 2a and the first groove 2b are interconnected. The first groove 2b has a semi-circular structure, allowing the ring 104 to fit perfectly within it. The first end 102 of the spiral coil 100 extends from the first groove 2b to the first U-shaped groove 2a, is supported within the first U-shaped groove 2a, and its end extends beyond the first U-shaped groove 2a. The high support column... The top of the column 4 is provided with a second U-shaped groove 4a for placing the second end 103. The inner side of the upper end of the column 4 is also provided with a second groove 4b that is compatible with the ring 104 on the second end 103. The second U-shaped groove 4a and the second groove 4b are interconnected. The second groove 4b is also semi-circular in structure. The ring 104 on the second end can also 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 limiting support 6 is installed on the base plate 1 on the side near the low support 2. A stop 7 that can abut against the coil body 101 is installed on the inner side of the limiting support 6. Understandably, the contact position between the stop 7 and the coil body 101 is exactly the starting position of the coil body 101.

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

[0058] Understandably, the detection device provided in this embodiment can be designed based on the spiral coil 100 of the standard part. That is, the position between the low support 2 and the high support 4 can be initially determined based on the distance between the two ends of the spiral coil 100 of the standard part. At the same time, the opening depth of the corresponding U-shaped groove in the low support 2 and the high support 4, as well as the height of the low support 2 and the high support 4, can be determined by combining the height of the first end and the second end. At the same time, the position and height of the limiting support 6 can be determined based on 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. 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 coil to be detected and the standard part (such as whether it can fit with the stop 7, whether it can be just stuck in the first U-shaped groove and the second U-shaped groove, etc.). Thus, it can be determined 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 base plate 1 on the side where the high support column 4 is installed, which is used to install the horizontal adjustment mechanism 3. This can reduce the weight, and the horizontal adjustment mechanism 3 can also be limited in the square groove 1a.

[0060] Specifically, the horizontal adjustment mechanism 3 includes a base 3a installed in a square groove 1a. Limiting plates 3b are respectively provided on the left and right sides of the upper end of the base 3a. A lead screw 3c and a slide rod 3d are provided between the two limiting plates 3b. There are two slide rods 3d, located on the front and rear sides of the lead screw 3c respectively. A slide table 3e is installed on the lead screw 3c, and the front and rear sides of the slide table 3d are slidably connected to the corresponding slide rod 3d. One end of the lead screw 3c passes through the outer limiting plate 3b and is connected to an adjustment handle 3f. The upper end face of the slide table 3e is detachably connected to the high support column 4.

[0061] Rotating the adjustment handle 3f can drive the slide table 3e to move horizontally along the length of the slide rod 3d, thereby causing the high support column 4 to move towards or away from the low support column 2.

[0062] The horizontal adjustment mechanism 3 provided in this embodiment can achieve precise adjustment of the high support column 4, thereby improving the detection accuracy.

[0063] Furthermore, combined Figure 5 As shown, a pointer 10 is also provided on the slide 3e, and a scale 11 is provided on the base plate 1 along the moving direction of the slide 3e; the scale 11 can also be fixed on the base plate 1 by threads and pins, and the pointer 10 is 0 in the default position; by setting the pointer 10 and the scale 11, the dimensional offset of the spiral coil 100 to be tested can be observed more intuitively.

[0064] In some embodiments, a first threaded hole (not shown) is provided in the first groove 2b, and a second threaded hole (not shown) 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 is understood that when performing coil size testing, only the ring at the first end 102 needs to be fixed; after testing, if it is necessary to place the spiral coil 100 on the testing device, the rings 104 at both ends can be fixed to the corresponding grooves simultaneously to prevent them from falling off and causing scratches.

[0065] Combination Figure 4 As shown, the detection device also includes a spiral tube clamp 12 for clamping the coil body 101. Two sets of spiral tube clamps 12 are provided, which are used to clamp the front and rear sides of the coil respectively. Each set of spiral tube clamps 12 is composed of two clamping plates 12a connected by screws. Both clamping plates 12a have corresponding crescent-shaped slots 12b that are adapted to the coil body 101. By setting the spiral tube clamps 12, the turn spacing and tube diameter of the spiral coil can be detected.

[0066] refer to Figure 6 As shown, the detection device also includes a lateral support 13 for replacing the high support 4. The top of the lateral support 13 is provided with a third U-shaped groove 13a for placing the second end 103. The inner side of the upper end of the lateral support 13 is provided with a circular scale 13b and a linear scale 13c. A step portion 13d is formed on the inner side of the upper end of the lateral support 13 at the lower end of the circular scale 13b and the linear scale 13c.

[0067] The side-shifting support 13 is used to replace the high support 4. Understandably, the bottom structure of the side-shifting support 13 is exactly the same as that of the high support 4, that is, the bottom can also form a lug for easy detachable connection with the slide table 3e. The main difference is in the upper end of the side-shifting support 13. When the center offset of the spiral coil to be tested is too high, and the ring 104 of the second end 103 is difficult to be locked in the second groove 4b of the high support 4, the high support 4 can be removed and the side-shifting support 13 can be installed. At this time, the step part 13 on the side-shifting support 13 can support the ring 104 of the second end 103. The center offset of the spiral coil 100 to be tested can be measured by the circular scale 13b and the linear scale 13c.

[0068] In some embodiments, weight-reducing holes 1b are provided on both the front and rear sides of the support block 8 in the middle of the base plate 1; by providing weight-reducing holes 1b, the overall weight of the detection device can be reduced, making it easier to transport and move. In some preferred embodiments, the weight-reducing holes 1b can be honeycomb-shaped perforated, which can increase the bending stiffness of the base plate 1 while reducing weight, ensuring the structural strength of the base plate 1.

[0069] Continue to refer toFigure 2 and Figure 3 As shown, a first through slot 2c is provided on the lower side of the low support column 2; a second through slot 4c is also provided on the lower side of the high support column 4; a pull handle 5 is also provided on the bottom plate 1 on the side near the high support column 4; the setting of the first slot 2c and the second slot 4c can also reduce the overall weight of the device, and can also be used as a handle.

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

[0071] 1) Assembly of the device: Install the low support column 2 and the limiting support column 6 on the left side of the base plate 1, install the support block 8 and the support pad 9 in the middle of the base 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 base plate 1.

[0072] 2) In the illustrated embodiment, with the side where the high support 4 is located as the right side and the side where the low support 2 is located as the left side, the detection device is placed horizontally. The high support 4 is adjusted to the right, away from the low support 2, by the horizontal adjustment mechanism 3 (rotating the adjustment handle 3f), so as to deviate from the 0 mark (to facilitate the insertion of the spiral coil to be detected). The first end 102 of the spiral coil 100 is placed in the first U-shaped groove 2a on the low support 2, and the ring 104 on the first end 102 is engaged in the first groove 2b. The second end 103 of the spiral coil 100 is placed in the second U-shaped groove 4a on the high support 4, and the ring 104 on 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 to the first groove 2b. Detect the distance between the outer side 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 move the high support 4 toward the low support 2, that is, to the left, until the second groove 4b and the outer side of the ring 104 at the second end fit together.

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

[0075] Understandably, if the second groove 4b fits into the outer surface of the second end ring 104, and the pointer points to the 0 mark, it can be judged as initially qualified; otherwise, it is unqualified and needs to be reworked and adjusted.

[0076] Furthermore, after initial qualification, the following steps are also included:

[0077] 5) Adjust the leveling mechanism 3 to the relaxed position, that is, adjust it to the right until it deviates from the 0 mark. Install the spiral clamp 12 on the spiral coil 100, and repeat steps 2)-3). Observe whether the scale value pointed to by the pointer is consistent with the scale value pointed to in step 4). That is, if it points to the 0 mark, the spiral coil is finally determined to be a qualified product; otherwise, it is a non-qualified product and needs to be reworked and adjusted.

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

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

[0080] Replace the high support 4 with the side support 13 and install the side support 13 on the leveling mechanism 3.

[0081] The horizontal adjustment mechanism 3 is used to adjust the side-biased support column 13 to the right to deviate from the 0 mark. The first end 102 of the spiral coil 100 is placed in the first U-shaped groove 2a on the low support column 2. The ring 104 on the first end 102 is locked in the first groove 2b. The second end 103 of the spiral coil 100 is placed in the third U-shaped groove 13a on the side-biased support column 13. The ring 104 of the second end 103 is placed on the step portion 13d.

[0082] The ring 104 on the first end 102 is connected to the first groove 2b using screws. The distance between the outer surface of the ring 104 on the second end 103 and the inner end face of the side-shifting support 13 is detected. If there is a gap, the horizontal adjustment mechanism 3 is adjusted to move the side-shifting support 13 toward the lower support 2 until the inner end face of the side-shifting support 13 and the outer surface of the ring 104 on the second end 103 are in contact with each other. The center offset of the spiral coil to be tested is determined by the circular scale 13b and the linear scale 13c on the side-shifting support 13.

[0083] Of course, when it is found that the lateral support 13 is needed for testing, the spiral coil to be tested is already a defective product and needs to be repaired and adjusted. At this time, the lateral support 13 is mainly used to record its specific offset and provide relevant data for adjustment.

[0084] In summary, the device provided by this invention:

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