Technical Field

[0001] The invention belongs to the technical field of silicon rod processing, and particularly relates to a rubber ring coplanarity measuring tool and a use method thereof. Background Art

[0002] As the main raw material for solar panels in the photovoltaic industry, monocrystalline silicon has a growing market demand. In the process of processing polycrystalline silicon raw materials into finished monocrystalline silicon rods, the polycrystalline silicon raw materials must first be melted and pulled out into rough rods with an average length of 3m through a single crystal furnace. In the process of processing the rough rods into finished square rods, they need to go through three processes: cutting, squaring, and polishing. When processing round rods in the squaring process, in order to ensure that the steel wire can smoothly square the round rods during the cutting process, it is necessary to ensure that the steel wire does not shake during the cutting process. The prerequisite for the steel wire not to shake during the cutting process is that the rubber rings have a high coplanarity accuracy.

[0003] In order to maintain a high coplanarity accuracy between the rubber rings in the related art, operators usually cooperate with each other using a steel ruler or a straightedge, with one person operating and the other observing. This not only increases labor costs, but also results in a low coplanarity accuracy of the rubber rings, thereby reducing the service life of the rubber rings. Summary of the invention

DETAILED DESCRIPTION

[0031] The content of the present invention can be more easily understood by selecting the following detailed description of the preferred implementation method of the present invention and the embodiments included. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those of ordinary skill in the art to which the present invention belongs. When there is a conflict, the definition in this specification shall prevail.

[0032] The present invention provides a tool for measuring the coplanarity of rubber rings, which solves the problem of manually adjusting the coplanarity of rubber rings in the prior art. Specifically, one person is responsible for placing a steel ruler or a ruler vertically on two coplanar guide wheel discs 300 inlaid with rubber rings, and another person needs to observe whether there is a gap between the guide wheel discs 300 and the steel ruler to determine whether the two rubber rings are coplanar. Manual operation based on experience will result in low accuracy of the coplanarity of the rubber rings. When the coplanarity accuracy of the rubber rings is low, the steel wire will shake during the cutting process, which will cause the steel wire to break on the one hand, and the rubber ring will be damaged on the other hand, which will increase the wire breakage rate of the steel wire and the wear and scrap rate of the rubber rings.

[0033] The technical concept of the present invention is to set a laser device 400 to emit laser rays, and at the same time fix an angular displacement measuring device 500 on the rubber ring. Under the premise of ensuring that the laser ray and the V-groove 201 of one of the rubber rings are in a colinear state, the laser ray performs a precise point-to-point operation on the V-groove 201 of the other rubber ring. During the measurement process, the V-groove 201 of the other rubber ring and the laser ray will produce an angular displacement deviation. The angular displacement deviation is accurately measured by the angular displacement measuring device 500, and the angular displacement signal is transmitted to the display screen. The position of the rubber ring that needs to be adjusted can be judged according to the positive and negative values ​​of the angular displacement displayed on the display screen, and the angle of the rubber ring is adjusted accordingly until the angular displacement displayed on the display screen is zero, which can effectively improve the accuracy of the coplanarity of the rubber ring. The above operation is convenient, can significantly reduce labor costs and steel wire breakage rate, effectively extend the service life of the rubber ring to a certain extent, greatly reduce the investment in the hardware cost of the rubber ring, achieve optimal allocation of resources, and improve the efficiency and stability of the process.

[0034] like Figure 1-2 As shown, a tool for measuring the coplanarity of rubber rings includes a fixing fixture 100, at least two rubber rings are connected to the fixing fixture 100, wherein the non-circumferential surface of the rubber ring, i.e., the radial plane, is fitted on the surface of the fixing fixture 100, so that in the initial state, one of the rubber rings is coplanar with the fixing fixture 100, the rubber ring coplanar with the fixing fixture 100 is named rubber ring one 210, and the other rubber ring is named rubber ring two 220, so as to reduce errors in subsequent adjustments.

[0035] A laser device 400 is provided at one end of the fixing fixture 100. The laser device 400 can emit laser beams. At the same time, the laser device 400 is coplanar with the rubber ring 210 on the fixing fixture 100. Specifically, the laser beam emitted by the laser device 400 is coplanar with the V-groove 201 of the rubber ring 210. The laser beam passes through the V-groove 201 of the rubber ring 210 and reaches the V-groove 201 of the rubber ring 220.

[0036] An angular displacement measuring device 500 is fixed on the rubber ring 1 210. When in use, the angular displacement measuring device 500 receives the laser beam emitted by the laser device 400 and measures the angular displacement of the V-groove 201 of the rubber ring 220. A display screen unit 600 is provided on the other side of the laser device 400. The display screen unit 600 is electrically connected to the angular displacement measuring device 500. The positive and negative conditions of the angular displacement can be displayed on the display screen to determine the position of the rubber ring that needs to be adjusted, and then the angle of the rubber ring is adjusted until the display screen shows that the angular displacement is zero, which means that the V-groove 201 of the rubber ring 1 210 and the rubber ring 220 are coplanar, which can effectively reduce the risk of steel wire breakage and the frequency of rubber ring wear, and effectively improve the service life of the rubber ring.

[0037] Optionally, a signal receiving module is included in the display screen unit 600, and the angular displacement signal obtained by the angular displacement measuring device 500 can be received through the signal receiving module. After processing the received signal, the signal receiving module can present the value and positive and negative trend of the angular displacement in real time on the display screen, which makes it easier for the operator to observe the deviation of the angular displacement, thereby being able to adjust the rubber ring more accurately, effectively improving the accuracy of the rubber ring coplanarity.

[0038] Please refer to Figure 3 Optionally, a guide wheel disc 300 coplanar with the rubber ring is fixed inside the rubber ring. In some embodiments, the guide wheel disc 300 is made of metal, and a NdFeB magnet layer 101 is provided on the surface of the fixing device, so that the guide wheel disc 300 can be adsorbed on the NdFeB magnet layer 101. The guide wheel disc 300 is a disc structure, and a groove body is provided at the outer circle of the guide wheel disc 300, and the groove body can be used to fix the rubber ring. A planar protrusion is provided at the center of the guide wheel disc 300, and the guide wheel disc 300 can be adsorbed on the surface of the fixing device through the protrusion. The guide wheel disc 300 where the rubber ring 220 is located is fixed on the machine table (not shown in the figure), and the guide wheel disc 300 of the rubber ring 220 is adjusted to facilitate the subsequent adjustment of the rubber ring position, so as to achieve the effect that the rubber ring 1 210 and the rubber ring 2 220 are coplanar.

[0039] Please refer to Figure 1Optionally, the laser device 400 includes a connecting rod 401 connected to one end of the fixing fixture 100. Specifically, a plate body is formed at one end of the fixing fixture 100 and is vertically arranged with the connecting rod 401 on the plate body. One end of the connecting rod 401 is connected with a supporting rod 402. The laser device 400 is fixed at the upper end of the supporting rod 402. The laser device 400 can emit laser rays. After the laser rays pass through the angular displacement measuring device 500, the angular displacement is accurately measured by the angular displacement measuring device 500, and the angular displacement signal is transmitted to the display screen. The employee can judge the position of the rubber ring guide wheel disc that needs to be adjusted according to the positive and negative conditions of the angular displacement displayed on the display screen, and then adjust the angle of the rubber ring guide wheel disc accordingly.

[0040] Optionally, the connecting rod 401 and the support rod 402 are movably connected by bolts, and the support rod 402 can be rotated around the connection point of the two by loosening and tightening the bolts, so that the emission angle of the laser device 400 can be adjusted. When the diameter of the rubber ring 1 210 is smaller than that of the rubber ring 220, the angle between the connecting rod 401 and the support rod 402 can be adjusted to an obtuse angle, so that the laser can still pass through the V-shaped groove 201 of the rubber ring 1 210 and the rubber ring 220 at the same time. When the diameter of the rubber ring 1 210 is larger than that of the rubber ring 220, the angle between the connecting rod 401 and the support rod 402 can be adjusted to an acute angle, so that the laser can still pass through the V-shaped groove 201 of the rubber ring 1 210 and the rubber ring 220.

[0041] Optionally, the laser device 400 is integrated with the display screen unit 600. The display screen unit 600 is arranged on the back of the laser unit 403. The display screen unit 600 is arranged on the back of the laser device 400 and has a size similar to that of the laser device 400. It is more convenient for manual use and the entire device is more compact, thereby improving the portability of the device.

[0042] Optionally, the angular displacement measuring device 500 includes a grating measuring unit 501 that is clamped to the outside of the rubber ring 210. In some embodiments, the angular displacement measuring device 500 is a grating angular displacement measuring unit that generates a light signal based on a grating pair. When the grating angular displacement sensor senses the angular displacement, a corresponding light signal change will occur, and these changes are captured and displayed by the grating digital display. In this way, the system can accurately measure and display the value of the angular displacement, accurately measure the angular displacement deviation through the angular displacement measuring device 500, and transmit the angular displacement signal to the display screen. According to the positive and negative values ​​of the angular displacement displayed on the display screen, the position of the rubber ring that needs to be adjusted can be determined, and the angle of the rubber ring can be adjusted accordingly until the angular displacement is displayed on the display screen as zero, which can effectively improve the accuracy of the coplanarity of the rubber ring. The above operation is convenient, can significantly reduce labor costs and steel wire breakage rate, and effectively extend the service life of the rubber ring to a certain extent.

[0043] Working principle: First, the tool is firmly fixed on the guide wheel disc 300 with the rubber ring 1 210 embedded therein. Under the premise of ensuring that the laser beam and the V-groove 201 of the rubber ring 1 210 are in a colinear state, the laser beam performs precise point-to-point operation on the V-groove 201 of the rubber ring 220 on another coplanar guide wheel disc 300. In this process, the V-groove 201 of the rubber ring and the laser beam will produce an angular displacement deviation. The grating angular displacement measuring device 500 is used to accurately measure this angular displacement, and its angular displacement signal is transmitted to the display screen. The employee can judge the position of the rubber ring guide wheel disc that needs to be adjusted based on the positive and negative conditions of the angular displacement displayed on the display screen, and then adjust the angle of the rubber ring guide wheel disc accordingly until the display screen shows that the angular displacement is zero.

[0045] S100, fixing the rubber ring to be tested in a fixing fixture 100;

[0046] S200, turning on the laser device 400 to emit laser light to the rubber ring to be tested;

[0047] S300, the angular displacement measuring device 500 measures the angular displacement between the rubber ring to be measured and the laser beam;

[0048] S400, the angular displacement measuring device 500 transmits the angular displacement signal to the display screen unit 600;

[0049] S500, judging the adjustment direction of the rubber ring to be tested according to the angular displacement parameter displayed on the display screen unit 600, and adjusting the rubber ring to be tested until the angular displacement displayed on the display screen unit 600 is zero.

[0050] In step S500, the step of adjusting the rubber ring to be tested includes:

[0051] S510, when the display screen shows that the angular displacement is a negative value, the rubber ring to be tested is adjusted to the left until the display screen shows that the angular displacement is 0;
