Among them, scintillation fiber detectors belong to scintillator detectors. Each optical fiber in the front-end scintillation fiber array can generate photons when particles pass through, and detect the position through the end silicon photomultiplier tube to determine the track of the material particles. Therefore, the preparation of a high-precision scintillation fiber track detection array can provide technical support for the hardware structure of track detection technology.

[0040] Example 1

[0041] like Figure 1-Figure 5 As shown, a manufacturing device for a scintillation optical fiber track detection array is provided, comprising: a frame 14 and an optical fiber reel 8 installed on the frame 14, a winding wheel 6, a movable guide mechanism 5, a wire pressing plate 4, a tension adjustment mechanism, a diameter gauge 11, a tension sensor and a main controller.

[0042] like Figure 3 As shown, the winding wheel 6 is capable of rotating, and a cutting groove 602 and a spiral winding groove 601 are provided on the circumferential surface; the cutting groove 602 is distributed along the axial direction of the winding wheel 6 and spans the winding groove 601; the winding wheel 6 is connected to the driving motor I, and the driving motor I is connected to the main controller; the groove width of the cutting groove 602 can be determined according to expert experience, and the driving motor I is installed on the frame 14.

[0043] The wire pressing plate 4 is located on one side of the winding wheel 6 and elastically rests against the circumference of the winding wheel 6; the structure of the wire pressing plate 4 can refer to the existing technology. As an optional option, the wire pressing plate 4 includes an adjustable spring, and a hinged first plate body and a second plate body, and the two ends of the adjustable spring are respectively connected to the first plate body and the second plate body; the first plate body is fixed on the frame 14, and the second plate body is located at the tangent position of the optical fiber entering the groove; the setting of the wire pressing plate 4 can ensure that the optical fiber is pressed into the specified position to avoid misalignment and tangled lines; by adjusting the pressure of the adjustable spring, the tightness of the wire pressing plate 4 can be controlled to prevent the occurrence of compression or uncompression, thereby ensuring the winding effect; in addition, the wire pressing plate 4 can also press the excess glue on the surface of the optical fiber into the two ends of the winding wheel 6 to make the glue detach from the winding wheel 6, thereby avoiding excessive glue affecting the winding result.

[0044] The optical fiber is led out from the optical fiber reel 8, and is wound on the winding wheel 6 after being led out through the tension adjustment mechanism and the movable guide mechanism 5, and the first layer of wound optical fiber is located in the winding groove 601; multiple layers are wound on the surface of the optical fiber winding wheel 6, the first layer of optical fiber is positioned by the thread groove, and the remaining layers are positioned by the gaps of the upper optical fiber.

[0045] The diameter gauge 11 and the tension sensor (not shown) are both located in the transmission path of the optical fiber from the optical fiber reel 8 to the winding wheel 6, and are used to detect the diameter of the optical fiber and the optical fiber transmission tension respectively. The tension adjustment mechanism is used to maintain a constant tension in the optical fiber transmission.

[0046] The diameter gauge 11 is a dual-axis laser diameter gauge; the diameter gauge 11 detects the diameter in the XY dual-axis direction to prevent the cross section of the optical fiber from being elliptical and affecting the winding. The diameter gauge 11 is electrically connected to the main controller; the diameter gauge 11 is added during the winding process to constantly detect the diameter of the optical fiber during the winding process, which can avoid the existing technology that the nodules generated during the optical fiber manufacturing process cause the wire diameter to be too thick and cause misalignment when preparing the scintillation optical fiber track detection array, thereby affecting the track detection accuracy.

[0047] like Figure 4As shown, the movable guide mechanism 5 can drive the optical fiber to move along the axial direction of the winding wheel 6. Specifically, the movable guide mechanism 5 includes a linear module, a first guide wheel 502 and a guide bracket 503; the guide bracket 503 is provided with a guide hole 504 allowing the optical fiber to pass through; the guide bracket 503 and the first guide wheel 502 are connected to the moving part of the linear module through the mounting seat 501, so that the linear module drives the guide bracket 503 and the first guide wheel 502 to move along the axial direction of the winding wheel 6; the driving motor II of the linear module is electrically connected to the main controller; as an optional option, the linear module is a ball screw, and the mounting seat 501 on which the first guide wheel 502 and the guide bracket 503 are installed is installed on the nut of the ball screw, and the driving motor II is connected to the screw of the linear module; the first guide wheel 502 is rotatably mounted on the mounting seat 501, and the guide bracket 503 is fixedly mounted on the mounting seat 501.

[0048] When the winding wheel 6 rotates one circle, the linear module drives the guide bracket 503 and the first guide wheel 502 to move forward a distance equal to the pitch of the winding groove 601, that is, the linear module moves axially along the winding wheel 6 to ensure that the optical fiber always enters the thread groove along the direction of the grain during the winding process; the mobile guide mechanism 5 and the winding wheel 6 cooperate to ensure the accuracy of the optical fiber winding position.

[0049] The tension adjustment mechanism can refer to the prior art, and the tension adjustment mechanism is used to maintain the stability of the tension of light transmission when winding the optical fiber. In this embodiment, the tension adjustment mechanism includes a mechanical damper 9 and a servo tensioner 10, and the mechanical damper 9 is installed on the optical fiber disk 8; the tension sensor and the servo tensioner 10 are installed on the transmission path of the optical fiber, and the servo tensioner 10 includes a servo motor and an adjustment wheel; the main controller is electrically connected to the servo motor, and can adjust the rotation of the servo motor according to the tension detected by the tension sensor to change the position of the adjustment wheel; the structure of the servo tensioner 10 can refer to the prior art.

[0050] like Figure 5 As shown, the main controller can control the movement of the mobile guide mechanism 5, the tension adjustment mechanism and the winding wheel 6 according to the detection data of the diameter gauge 11 and the tension sensor; the main controller is electrically connected to the diameter gauge 11, the drive motor I, the servo motor and the drive motor II of the servo tensioner 10, and the main controller can control the movement of the drive motor I and the drive motor II according to the optical fiber diameter monitored by the diameter gauge 11; it can also control the rotation of the servo motor according to the optical fiber tension detected by the tension sensor; considering the stability of industrial control, the RS485 communication protocol is adopted to transmit data, and the equipment is operated through switch quantity and pulse drive.

[0051] Furthermore, the distance between the detection point of the caliper 11 and the winding surface of the winding wheel 6 is greater than twice the circumference of the winding wheel 6. During the manual removal process, after the winding wheel 6 returns to zero, it can still ensure that the end of the winding wheel 6 to the fiber node position exceeds the circumference of the winding wheel 6; after the node is removed, the optical fiber is cut to a position where the length of the end of the winding wheel 6 is the circumference of the winding wheel 6, and the new optical fiber is glued into the cutting groove 602 by glue. After the process is completed, the winding is continued. At this time, the continued winding can make the bonding point just located in the cutting groove 602; after the subsequent overall winding is completed, the bonding position is cut off to ensure that the bonding point will not affect the detection effect of the overall optical fiber array, that is, there is no bonding point on the overall optical fiber array, and the finished product is smooth and complete.

[0052] Furthermore, the manufacturing device also includes an electrical control box 12, a human-computer interaction device and a position switch; the electrical control box 12 is installed on the frame 14, and a motor driver and a power management module connected to the main controller are arranged in the electrical control box 12, and the main controller is also installed in the electrical control box 12; the human-computer interaction device includes a touch screen 3, a mechanical button 2 and an alarm light 1; the touch screen 3, the mechanical button 2 and the alarm light 1 are all connected to the main controller; the touch screen 3 can manually input the number of winding layers, control the start and stop of the equipment and display the winding progress in real time; the position switch (not shown in the figure) is installed on the frame 14 and close to the winding wheel 6, and the position switch is used to detect whether the cutting groove 602 of the winding wheel 6 is in the initial set position, and the structure of the position switch can refer to the prior art.

[0053] A glue overflow groove 7 is also provided below the winding wheel 6 for holding dripping glue; a second guide wheel 13 rotatably connected to the frame 14 is also provided on the transmission path of the optical fiber to be wound, and the structure and number of the second guide wheel 13 refer to the prior art.

[0054] The rack 14 is constructed of high-strength aluminum profiles and is encapsulated with aluminum plates. The base at the bottom of the rack 14 is heightened and weighted to make the equipment shock-resistant, pressure-resistant and moisture-proof. Of course, pulleys and brackets can also be installed at the bottom as needed to achieve fixation and movement.

[0055] The overall winding process is completed by the main controller controlling the driving mechanism, thereby driving the actuator. During the preparation process, the fiber winding parameters can be detected to ensure the quality of the fiber array while greatly reducing the labor cost and improving the winding efficiency. The equipment uses a damper 9 and a servo tensioner 10 to synchronously control the fiber tension to prevent sudden changes in tension from affecting the arrangement of the fiber array, while avoiding excessive tension from damaging the fiber and affecting the light guide; equipped with a fiber diameter gauge 11, the fiber can be removed in time if it is too thick or too thin, greatly ensuring the quality of the fiber array; a pressure plate 4 and an overflowing glue groove 7 are installed to press the fiber on the winding wheel 6 to ensure that the fiber is neatly arranged, and the overflowing glue is discharged in time to prevent overflowing glue and dislocation from affecting the fiber array structure.

[0056] Example 2

[0057] like Figure 6 As shown, a method for manufacturing a scintillation optical fiber track detection array is provided, comprising the following steps:

[0058] S1: Apply glue to the surface of the winding wheel 6 and fix the winding starting point of the optical fiber on the winding wheel 6.

[0059] Specifically, fixing glue can be applied manually to the surface of the winding wheel 6 to ensure the winding quality, and the winding starting point can be fixed on the pre-processed screw hole of the winding wheel 6; of course, in some other embodiments, glue can also be applied with the help of an automatic glue coating device.

[0060] S2: The main controller controls the driving motor I of the winding wheel 6 and the driving motor II of the moving guide mechanism 5 to perform a zero return action, so that the cutting groove 602 is at the initial setting position.

[0061] After starting, the driving motor I of the winding wheel 6 and the driving motor II of the moving guide mechanism 5 start to run, giving priority to achieving the zero return of the winding wheel 6, and the zero return situation is determined by the position switch.

[0062] S3: According to the set number of winding layers, the main controller controls the drive motor I of the winding wheel 6 and the drive motor II of the movable guide mechanism 5 to perform multi-layer winding of the optical fiber; during the winding process, the diameter gauge 11 monitors the diameter of the optical fiber, and the tension sensor monitors the tension transmitted by the optical fiber. When the optical fiber diameter or optical fiber tension does not meet the requirements, the main controller issues corresponding operation instructions to avoid winding defects.

[0063] After the equipment returns to zero, it starts to wind the flashing optical fiber array. The winding wheel 6 rotates to wind the optical fiber array. The linear module cooperates with the winding wheel 6 by axial movement. Every time the winding wheel 6 rotates one circle, the linear module moves forward a pitch distance. Under the action of the wire pressing plate 4, the optical fiber accurately enters the pre-processed thread groove. During the process, the damper 9 controls the rotation damping of the optical fiber disk 8 through mechanical adjustment to pre-adjust the tension. The servo tensioner 10 detects the optical fiber tension to determine whether it meets the set threshold range, and adjusts the cam position in real time to accurately control the optical fiber tension. It works synchronously with the damper 9. The dual control ensures uniform tension and prevents winding errors caused by sudden changes in tension. The optical fiber diameter gauge 11 monitors the optical fiber diameter in real time to ensure the winding quality. When the optical fiber diameter exceeds the set threshold range, it will alarm in time, and manual intervention will be performed to remove defective optical fibers to prevent winding defects caused by excessively thick optical fibers.

[0064] When the optical fiber tension does not meet the requirements, the main controller controls the position of the adjustment wheel of the tension adjustment mechanism in real time to maintain the stability of the tension of the optical fiber transmission.

[0065] like Fig. 9 As shown, when the optical fiber diameter does not meet the requirements, the main controller controls the driving motor I of the winding wheel 6 and the movable guide mechanism 5 to perform a return to zero operation, and after the return to zero operation, stops the movement of the winding wheel 6 and the movable guide mechanism 5; manually removes part of the optical fiber whose diameter does not meet the requirements, and bonds the interface of the optical fiber in the cutting groove 602; the main controller controls the driving motor I of the winding wheel 6 and the movable guide mechanism 5 to continue to perform the winding operation until the set number of winding layers is reached.

[0066] When performing multi-layer winding of optical fiber, after each layer is wound, the winding end point of the current layer needs to be fixed and glue is applied again to facilitate bonding of the optical fiber when the next layer is wound.

[0067] Specifically, the distance between the winding end of each layer and the caliper 11 is relatively far, ensuring that the distance between the nodule detection point and the winding surface is relatively far, which is greater than the distance of two turns of the winding wheel 6; that is, during the manual removal process, after the winding wheel 6 returns to zero, it can still ensure that the cutting groove 602 of the winding wheel 6 to the position of the optical fiber nodule exceeds the circumference of the winding wheel 6; after the nodule is removed, the optical fiber is cut to the position of the cutting groove 602, and the new optical fiber is glued to the position of the cutting groove 602 by glue. After the process is completed, the winding is continued, and at this time, the winding can make all the bonding points just face the cutting groove 602.

[0068] The wire pressing plate 4 can not only press the optical fiber, but also eliminate the overflowing glue. It can press the overflowing glue during the optical fiber winding process to both sides, so that the glue drips from the wheel side into the overflowing glue groove 7, and is subsequently processed manually to prevent the overflowing glue from causing defects in the optical fiber array. At the same time, the degree of compression of the wire pressing plate 4 can also be adjusted by the spring tension.

[0069] S4: After the winding is completed and the glue is completely dry, the wound optical fiber array is cut from the position where the cutting groove 602 is located, so that the optical fiber array is separated from the winding wheel 6.

[0070] like Fig. 9 As shown, after the subsequent overall winding is completed, the bonding position of the optical fiber in the cutting groove 602 is cut off to ensure that the bonding point will not affect the detection effect of the overall optical fiber array, that is, there is no bonding point on the overall optical fiber array, ensuring that the finished product is smooth and complete.

[0071] The successfully wound scintillating fiber array is shown in Figure 7 As shown in the figure, the multi-layer optical fiber arrays are arranged neatly. Common defects in the process are Figure 8 As shown, defects such as misalignment, failure to guide light, and missing optical fibers are very likely to occur during the winding process. Figure 8 Defect A in the figure is the misalignment caused by the excessively thick wire diameter. Specifically, if the optical fiber diameter is too large and is not removed in time, the next layer of optical fibers will be misaligned and arranged in a chaotic manner. Figure 8 Defect B in the figure is caused by excessive tension affecting light guidance. Specifically, uneven tension during fiber winding will lead to uneven arrangement. Excessive tension will also directly affect the fiber light guidance, resulting in a damaged array. Figure 8 Defect C in the figure is caused by the misalignment and missing due to the absence of the wire pressing plate 4. Specifically, if the optical fiber is directly wound without pressure to compact it, some optical fibers may not accurately enter the thread groove or the set gap, and may even be missing or misaligned. Figure 8 Defect D in the above is caused by glue overflow and misalignment due to the failure to drain the glue. Specifically, if the excess glue formed by the overflow is not drained in time, it will also affect the arrangement of the next optical fiber, lift up the upper optical fiber, and cause misalignment. Therefore, the automatic preparation system for the scintillation optical fiber track detection array of the present invention is adopted to carry out the winding of the optical fiber array, which can effectively avoid Figure 8 The various defects shown in the figure not only improve the process automation, but also further improve the product quality, which has great benefits and practical value.
