Description

Technical Field

[0001] The present invention relates to the field of detection technologies, and particularly to a strip lateral bending detection device and method based on a laser emitter. Background Art

[0002] Tantalum strips for semiconductors are important sheet materials for magnetron sputtering tantalum ring parts, and their preparation involves various process technologies such as powder mixing, cold isostatic pressing, hot press sintering, forging plastic deformation, and wire cutting. However, during the process of processing tantalum plates into tantalum strips by wire cutting, lateral bending often occurs. To prevent the bent tantalum strips from flowing out, it is necessary to perform a correction process on them.

[0003] Traditional lateral bending measurement methods require placing the tantalum strip vertically on a horizontal surface and using a feeler gauge to measure the gap between the tantalum strip and the horizontal surface. Although this method is intuitive, it is complex to operate and relies on manual labor, resulting in low efficiency.

[0004] To solve the above problems, CN221055710U discloses an ECP board flatness and lateral bending degree measuring device, which provides a detection improvement solution. The measuring device consists of a horizontal guiding plate, a clamping member, a vertical measuring scale, and a measuring scale fixing device. Its main working principle is to fix the measuring device outside the workpiece to be measured through the clamping member. When the top pressing part of the vertical measuring scale moves with the bending or unevenness of the workpiece, the bending degree is accurately measured by sliding the measuring scale fixing device.

[0005] However, the above method has the following disadvantages when measuring the lateral bending degree:

[0006] (1) Similar to the traditional measurement method, this measuring device can still only measure single sheets one by one, with low efficiency and room for improvement;

[0007] (2) The manual reading of the vertical measuring scale depends on the operator, and there is still uncertainty in improper manual operation;

[0008] (3) Components such as the vertical measuring scale and the top pressing part may have frictional contact during the moving measurement process, thereby introducing errors or causing damage to the sheet;

[0009] (4) This measuring device has poor flexibility and requires replacing measuring tools or adjusting the equipment, and cannot quickly switch between various materials and objects of different shapes.

[0010] To overcome the deficiencies of the prior art, new devices and methods for detecting the bending degree need to be developed. Summary of the Invention

[0011] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a long-strip lateral bending detection device and method based on a laser emitter, which can batch and quickly detect whether a long strip is laterally bent through a laser beam, greatly saving manual operation and improving the detection efficiency.

[0012] To achieve this purpose, the present invention adopts the following technical solutions:

[0013] In the first aspect, the present invention provides a long-strip lateral bending detection device based on a laser emitter, and the long-strip lateral bending detection device includes a laser emitter, a sample placement device, an alarm, and a laser detection module;

[0014] Among them, one end of the sample placement device is provided with the laser emitter, and the laser detection module is provided at the other end of the sample placement device away from the laser emitter, and the laser detection module is used to receive the laser beam emitted by the laser emitter;

[0015] The sample placement device is provided with a sample setting groove for placing a long-strip sample to be tested; the length direction of the long-strip sample to be tested is parallel to the laser beam emitted by the laser emitter;

[0016] The alarm is connected to the laser detection module through a signal.

[0017] The long-strip lateral bending detection device provided by the present invention is provided with a sample placement device between the laser emitter and the laser detection module. After the sample is placed in the sample placement device, the laser is emitted, and the laser beam is adjusted to a position equivalent to the height of the sample. When the degree of bending of the sample exceeds the preset value, the sample will block the laser beam, resulting in the laser detection module being unable to receive the signal of the laser beam. At this time, the alarm sounds an alarm, achieving the effect of quickly identifying unqualified long-strip samples with side bending.

[0018] It should be noted that the length of the long strip sample to be measured targeted by the present invention is 0.8 to 1.5 m. For example, it can be 0.8 m, 0.88 m, 0.96 m, 1.04 m, 1.12 m, 1.19 m, 1.27 m, 1.35 m, 1.43 m, or 1.5 m, etc., but not limited to the listed values. Other unlisted values within this range are equally applicable; while the width of the long strip sample to be measured is only 3 to 8 cm. For example, it can be 3 cm, 3.6 cm, 4.2 cm, 4.7 cm, 5.3 cm, 5.8 cm, 6.4 cm, 6.9 cm, 7.5 cm, or 8 cm, etc., but not limited to the listed values. Other unlisted values within this range are equally applicable. The height of the long strip sample to be measured is only 0.5 to 1.0 cm. For example, it can be 0.5 cm, 0.56 cm, 0.62 cm, 0.67 cm, 0.73 cm, 0.78 cm, 0.84 cm, 0.89 cm, 0.95 cm, or 1.0 cm, etc., but not limited to the listed values. Other unlisted values within this range are equally applicable.

[0019] Preferably, the sample placement device includes at least two rows of sample setting groove members.

[0020] Preferably, at least one notch is provided on each row of the sample setting groove members, and the notches on each row of the sample setting groove members are correspondingly arranged.

[0021] It should be noted that in the present invention, it is preferred to set a larger number of notches, so that multiple long strip samples to be measured can be detected in one laser scanning process, and the detection efficiency is higher.

[0022] Preferably, the sample placement device includes a bottom support plate provided at the bottom of the sample setting groove member. At least two mounting positions are provided on the upper surface of the bottom support plate.

[0023] In the present invention, it is preferred to use a bottom support plate, so that at least two sample placement devices can be configured for each detection device. During the detection of the first batch of samples, the long strip samples to be measured can be placed in another set or at least two sets of sample placement devices. After the detection of the first batch of samples is completed, the sample placement device on the bottom support plate can be directly set on the base for direct detection, so as to realize the continuous detection of the long strip lateral bending detection device for the long strip samples to be measured, and the detection efficiency is higher.

[0024] Preferably, the mounting position is a first groove corresponding to the bottom of the sample setting groove member.

[0025] Preferably, the long strip lateral bending detection device further includes a base, and the laser emitter, the sample placement device, the alarm, and the laser detection module are all provided on the base.

[0026] Preferably, a convex knot body is provided at the bottom of the bottom support plate, and the convex knot body is matched with a second groove on the base of the long strip lateral bending detection device.

[0027] Preferably, a translation rail is provided at one end of the base, the laser emitter is arranged on the translation rail, and the translation direction of the translation rail is perpendicular to the laser beam emitted by the laser emitter.

[0028] In the present invention, the long side direction of the long strip sample to be measured is taken as the x-axis, and the direction perpendicular to the x-axis on the horizontal plane is taken as the y-axis. Among them, the moving direction of the translation rail is the y-axis direction, and the laser emitter moves through the translation rail to realize the bending degree detection of multiple long strip samples to be measured.

[0029] Preferably, a laser sensor base is provided at the lower part of the laser emitter, and the laser sensor base is installed on the translation rail.

[0030] Preferably, a servo motor is provided on the laser sensor base for driving the laser sensor base to translate on the translation rail.

[0031] Preferably, a sliding groove for adjusting the height of the laser beam is provided on the laser sensor.

[0032] Preferably, the long strip lateral bending detection device further includes a height adjustment component arranged below the translation rail.

[0033] The present invention can detect long strip samples to be measured with different heights by setting the height adjustment component.

[0034] Preferably, the alarm includes an audible alarm and / or a visual alarm.

[0035] Preferably, the alarm is arranged above the laser emitter.

[0036] Preferably, at one end close to the laser detection module, a sliding table is provided on the base, and the sliding direction of the sliding table is parallel to the direction of the laser beam. The laser detection module is fixedly arranged on the sliding table and slides along with the sliding of the sliding table.

[0037] In the present invention, the sliding direction of the sliding table is the x-axis direction, so that the distance between the laser detection module and the laser emitter can be adjusted, and thus long strip samples to be measured with different lengths can be adapted, making the detection range of the long strip lateral bending detection device wider.

[0038] The sliding range of the sliding table is at the position of 50% to 100% of the base along the direction of the laser beam. For example, it can be 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95% or 100%, etc., but not limited to the listed values. Other unlisted values within this range are equally applicable.

[0040] Preferably, the sliding table is an X-axis dovetail groove type precision sliding table.

[0041] In a second aspect, the present invention provides a method for detecting lateral bending of a long strip based on a laser emitter. The method for detecting lateral bending of the long strip uses the device for detecting lateral bending of a long strip based on a laser emitter described in the first aspect.

[0042] Since the method for detecting lateral bending of a long strip provided in the second aspect of the present invention uses the device for detecting lateral bending of a long strip based on a laser emitter described in the first aspect, it not only has high detection efficiency, but also accurate detection results. For the long strip samples to be measured with an aspect ratio of 80 to 300:1, samples with excessive bending can be detected.

[0044] Furthermore, the present invention has relatively high requirements for the detection accuracy of the bending degree of the long strip sample to be measured. When the bending degree exceeds 0.5 mm, it is determined that the long strip sample to be measured is unqualified, that is, the detection accuracy of the detection device is required to reach below 0.5 mm. This also requires that when setting the height, the height of the laser beam can be set to be only 0.5 mm higher than the height of the long strip sample to be measured.

[0045] Preferably, the method for detecting lateral bending of the long strip includes the following steps:

[0046] S1. Place the long strip sample to be measured in the sample setting groove member, and place the sample placement device on the base.

[0047] S2. Adaptively adjust the height of the laser emitter according to the height of the long strip sample to be measured, and start the laser emitter to emit a laser beam;

[0048] S3. The laser emitter translates on the translation track and determines whether the lateral bending value of the long strip sample to be measured is qualified according to the laser signal detected by the laser detection module.

[0049] Preferably, determining whether the lateral bending value of the long strip sample to be measured is qualified includes: if the laser detection module receives a laser signal, the long strip sample to be measured is qualified. If the laser detection module does not receive a laser signal, the translation of the laser emitter is immediately stopped and fixed, and at this time, the long strip sample corresponding to the laser beam emitted by the laser emitter is determined to be unqualified.

[0105] This embodiment provides a long strip lateral bending detection device based on a laser emitter. Except that the sample placement device does not have a bottom pallet, and instead, a convex knot directly mating with the second groove on the base is provided at the bottom of the sample setting groove member, the rest are the same as those in Embodiment 1 and will not be elaborated here.

[0106] In this embodiment, since the bottom pallet is not designed, each row of sample setting groove members is combined with the base separately. After the previous batch of samples is detected, it is necessary to remove the previous batch of samples from the sample setting groove members and then set the next batch of long strip samples to be tested. Even if there are multiple sets of sample setting groove members, without a bottom pallet, the individual sample setting groove members are isolated from each other, and the effective installation of the long strip samples to be tested cannot be achieved independently of the detection device, resulting in a significant decrease in the detection efficiency compared with Embodiment 1.

[0107] Embodiment 5

[0108] This embodiment provides a long strip lateral bending detection device based on a laser emitter. Except that no slide is provided on the base, the rest are the same as those in Embodiment 1 and will not be elaborated here.

[0109] In this embodiment, since no slide is provided, it can only be adapted to long strip samples to be tested within a relatively narrow length range, and the detectable range is greatly reduced compared with Embodiment 1.

[0110] Embodiment 6

[0111] This embodiment provides a long strip lateral bending detection device based on a laser emitter. Except that no chute is provided, the rest are the same as those in Embodiment 1 and will not be elaborated here.

[0112] In this embodiment, since no chute is provided, the height can only be adjusted by the height adjustment component, and the detection accuracy that can be achieved is inferior to that of Embodiment 1.

[0113] The present invention illustrates the detailed features of the present invention through the above embodiments. However, the present invention is not limited to the above detailed features, that is, it does not mean that the present invention must rely on the above detailed features to be implemented. Those skilled in the art should understand that any improvement to the present invention, the equivalent replacement of the technical features selected by the present invention, the addition of auxiliary technical features, and the selection of specific ways, etc., all fall within the protection scope and the disclosure scope of the present invention.
