Description

Technical Field

[0001] The invention relates to the technical field of optical end face detection, in particular to an automatic grouping detection device for end faces of quartz tubes. Background Art

[0002] The quartz tube end face measuring device is designed for efficient and accurate detection of the single-sided quality of quartz tubes. It adopts ultraviolet light irradiation technology and uses ultraviolet light sources with specific wavelengths to evenly irradiate the end faces of quartz tubes to enhance the visibility of surface defects. The high-precision camera then captures and uploads clear images to the advanced detection system. The system analyzes the image through precise algorithms and automatically determines whether the quality of the quartz tube end faces is qualified. Qualified products will be automatically passed by the system, and unqualified products will be accurately identified and rejected, ensuring the efficiency and stability of the detection process.

[0003] However, there are still some problems with the existing quartz tube end face detection device: First, in the existing quartz tube end face detection device, the quartz tube is usually placed on a fixture for fixing, and then irradiated with ultraviolet light, and the image is uploaded to the system for analysis. However, since the end face of the quartz tube is not completely flat, this will produce a depth of field effect during the actual shooting process. The depth of field refers to the front and rear distance range of the subject measured by the imaging that can obtain a clear image at the front of the camera lens or other imager. When the end face of the quartz tube is uneven, the distance between different parts and the camera will be different, resulting in some areas being clear and some areas being blurred in the captured image.

[0004] This depth of field effect has a significant impact on the quality inspection of the end face of the quartz tube. First, the blurred area covers up the surface defects, making it impossible for the system to accurately identify and judge the quality of the quartz tube. This will cause unqualified quartz tubes to be misjudged as qualified, and then flow into the market or the next production link, causing quality risks. Secondly, the depth of field effect will also make the system pay too much attention to the clear area, thereby ignoring other existing defects, resulting in one-sided detection.

[0005] Secondly, in the production process of quartz tubes, inspection will be carried out immediately after production, so that problems in the production process can be discovered immediately and the production process can be adjusted in time. However, correspondingly, the cost of dust-free space is reduced, and the quartz tube needs to be cleaned manually. Although the operator cleans the quartz tube, the cleaning work is quite difficult due to the small inner wall space of the quartz tube. In addition, most of the inspection equipment is in a relatively closed space. At the same time, there are many electrical appliances in the inspection equipment, so it is easier to absorb dust. This makes it inevitable that dust will be present on the outer and inner walls of the quartz tube during the inspection. When the inspection is carried out, the dust appears as a bulge on the image. This bulge-like image interference will cause the inspection system to misjudge and judge the originally qualified product as an unqualified product.

[0006] From the perspective of the production process, this misjudgment will lead to unnecessary cost increases. The originally qualified quartz tubes will be mistakenly judged as unqualified and will be eliminated from the production process, which means a waste of production resources. In the subsequent processing links, even if there is a manual re-inspection, due to the small end face area of ​​the quartz tube, the raised interference caused by dust is not easy to be accurately identified in the image, and it is difficult to find the problem through manual re-inspection. This makes it difficult to correct this misjudgment, and the problem of resource waste in the production process continues to exist and worsen.

[0007] To this end, the present invention provides a quartz tube end face automatic grouping detection device. Summary of the invention

The gantry close to the electric control panel is fixedly connected to the top of the guide rail, and its opening direction is downward, and the gantry away from the electric control panel is penetrated and fixedly connected to the bottom of the guide rail, and its opening direction is upward.

[0022] Preferably, the overall size of the arc surface groove is larger than the outer wall size of the quartz piece, and the overall size of the curved surface groove is smaller than the inner wall size of the quartz piece.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In order to solve the problem in the prior art that the depth of field effect affects the accuracy of quality inspection, the present invention introduces a rotation mechanism of the power rod to drive the L-shaped power seat to rotate synchronously, thereby pulling the detection module to move along a specific trajectory, so that the detection module can achieve a movement mode of first moving away and then approaching, and then by changing the distance between the detection module and the end face of the quartz tube, the depth of field effect is effectively improved. In the process of moving away from the quartz tube, the detection module can capture a wider field of view, which helps the detection module to focus more accurately on the end face of the quartz tube when approaching later. As different parts gradually approach, the detection module can gradually adjust the focal length to ensure that a more comprehensive and clear image can be captured when it finally returns to the middle position. This movement method not only enables the detection module to adapt to the unevenness of the end face of the quartz tube, but also captures more details and features, thereby improving the accuracy and reliability of the quartz tube end face quality inspection. This improvement not only helps to reduce misjudgment caused by depth of field effects, such as the problem of blurred areas covering up surface defects, but also improves the comprehensiveness and stability of detection, ensuring that unqualified quartz tubes will not be misjudged as qualified, thereby effectively avoiding quality risks.

[0024] Compared with the existing technology, this improved solution effectively overcomes the challenges brought by the depth of field effect by dynamically adjusting the distance between the detection module and the end face of the quartz tube during the detection process. The existing technology often relies on a fixed detection module position and a single shooting angle, which makes it difficult to deal with image quality problems caused by the uneven end face of the quartz tube. Therefore, the present invention has unique advantages in improving detection accuracy and adaptability.

[0025] Among them: when the driving motor rotates to drive the bearing block to rotate, since the driving sleeve above is limited, the rotation of the bearing block will pull the vertical limit column through the L-shaped power seat and the power rod to move in a rectangular trajectory, and the existence of the travel spring makes this movement process more stable and controllable, which helps to reduce the vibration and impact caused by mechanical movement, thereby protecting the stability and accuracy of the detection module.

[0026] Among them: when the driving sleeve moves in a rectangular trajectory, the vertical limit column will stop at the farthest point and the closest point of the stroke. At this time, the driving sleeve slides on the surface of the vertical limit column. This stop design helps the detection module to perform more stable video or detection at a specific position. By staying, the detection module can get more sufficient time to capture clear images, especially in the key area of ​​the end face of the quartz tube, thereby further improving the accuracy and reliability of the detection.

[0027] Among them: in the process of the detection module first moving away and then approaching and finally returning to the middle, the process of moving away from the quartz tube helps the detection module capture a wider field of view and provides background information for subsequent approaching and detailed detection, while the process of approaching allows the detection module to focus on the end face of the quartz tube at a closer distance and capture more details and features. This movement mode of first moving away and then approaching effectively combines a wide-angle field of view and detail capture, thereby improving the comprehensiveness and accuracy of detection.

[0028] While achieving the above effects, the present invention also has the following effects: since the rectangular motion trajectory of the driving sleeve causes the detection module to perform linear motion, compared to the use of a cylinder that can drive linear motion, the structure in the present invention uses standard parts, which not only has lower manufacturing costs but also is easier to maintain. At the same time, when the cylinder is driven, pressure fluctuations will occur due to the micro-elasticity of the gas. This fluctuation will interfere with the accuracy of the detection process that focuses on precision. The structure of the present invention can also stay at the stroke end during stable motion, thereby ensuring motion accuracy while achieving effective cost control.

[0029] 2. This improvement scheme introduces a fan to allow the fan to enter the interior of the sliding disk through the air pipe, and finally blow to the inner wall and upper outer wall of the quartz tube through the arc groove and the curved groove respectively. Therefore, the quartz tube is cleaned in time before detection, which effectively reduces the misjudgment problem caused by dust, thereby avoiding unnecessary waste of production resources. At the same time, timely cleaning also ensures the accuracy and reliability of the detection process and improves production efficiency.

[0030] Compared with the prior art, the improved scheme effectively cleans the quartz tube before detection, greatly reducing the impact of dust on the detection results. In the prior art, although the operator will clean the quartz tube, due to the particularity of the quartz tube structure and the airtightness of the detection environment, the dust is still difficult to completely remove. The present invention directly acts on the inner and outer walls of the quartz tube through a targeted blowing design, thereby significantly improving the cleaning effect.

[0031] Among them: since the arc groove is larger than the outer wall diameter of the quartz part, and the curved groove is smaller than the inner wall diameter of the quartz part, based on the Bernoulli principle, negative pressure will be generated in the process of not contacting the quartz part, thereby taking away the dust on the surface. Therefore, the anti-dust intrusion component not only effectively prevents pollutants and dust from scratching the quartz part, but also ensures the non-contact nature of the cleaning process, avoiding damage to the quartz part caused by the cleaning operation.

[0032] Among them: ‌Since the internal space of the diverter disc is large and the outlet of the first output slot is small, the air will gradually expand outward when released. Part of the gas will be pushed to the chute by the released gas, and as the air is continuously released, the gas at the chute will follow the gas at the first output slot, thereby generating a spiral gas under the guidance of the chute. After this spiral gas is mixed with the gas at the first output slot, all the gases have a spiral motion trend. This design keeps most of the gas in a relatively stable state, helps maintain the gas shape, prevents gas loss, and thus improves the stability and durability of the cleaning effect.

[0033] Among them: since the filter is located at the other end of the gas, when the gas impacts the filter, pollutants such as dust will be concentrated on the filter, thereby achieving effective collection and treatment of dust. At the same time, since the filter is installed in the sliding disk, it is convenient to replace and maintain, which not only improves the cleaning efficiency, but also reduces the operation difficulty and maintenance cost.

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] It should be noted that the detection module 13 can detect the end face of the quartz tube through the cooperation of the ultraviolet light illuminator 1 and the camera, and the detection data will be uploaded to the electronic control panel 14, and the electronic control panel 14 will determine whether it is a good product. The auxiliary detection unit will perform reverse fill light on the detection module 13 through the ultraviolet light illuminator 2, thereby improving the accuracy of the detection.

[0049] At the same time, since the detection module 13 is set on one side, the end face of the quartz tube can be detected more accurately, thereby avoiding light interference caused by simultaneous detection on both sides.

[0050] The detection module 13 and the auxiliary detection unit can both adopt relevant products available on the market. The structure and working principle of these products belong to the existing technology, so they will not be described in detail later.

[0051] Example 1, please refer to Figure 1 and Figure 5 As shown, the automatic grouping detection device for the end faces of quartz tubes includes an operating cabinet 11, a guide rail 12 is installed on the top of the operating cabinet 11, a placement table 121 is installed on the top of the guide rail 12, a detection module 13 is installed on the outer surface of the guide rail 12, and a dynamic stop detection component 2 for reducing the depth of field effect during the detection process is arranged inside the operating cabinet 11. The dynamic stop detection component 2 includes an L-shaped power seat 23 and a power rod 24 for pulling the detection module 13 by rotating itself, thereby reducing the depth of field effect that affects the detection accuracy.

[0052] Please refer to Figures 1 to 5 As shown, the dynamic stop detection component 2 also includes a vertical limit column 21, which is fixedly connected to the bottom of the detection module 13, and the end of the guide rail 12 close to the detection module 13 is connected to the interior of the operating cabinet 11, and the surface of the vertical limit column 21 is slidably connected with a driving sleeve 22, and the outer surface of the driving sleeve 22 is rotatably connected to the outer surface of the L-shaped power seat 23. The power rod 24 is fixedly connected to the bottom of the L-shaped power seat 23, and the outer surface of the power rod 24 is slidably connected with a bearing block 26, and a travel spring 25 is fixedly connected between the top of the bearing block 26 and the bottom of the L-shaped power seat 23. An electric control panel 14 is installed on the inner surface of the top side of the operating cabinet 11, and a driving motor 27 is installed on the inner wall of the bottom side of the operating cabinet 11, and the output shaft of the driving motor 27 is rotatably connected to the bearing block 26.

[0053] It should be noted that the electric control panel 14 electrically controls the start and stop of the drive motor 27, and the electric control panel 14 can control the drive motor 27 to rotate only one circle when it starts through the built-in program. An auxiliary detection unit is installed on the side of the guide rail 12 away from the detection module 13, and the auxiliary detection unit is electrically controlled to start and stop by the electric control panel 14. The detection module 13 includes a slide, a purple light irradiator and a camera. The slide is slidably connected to the outer surface of the guide rail 12, and the purple light irradiator and the camera are respectively installed on the outer surface of the slide. The auxiliary detection unit includes a purple light irradiator 2 and a column. The column is installed on the outer surface of the operating cabinet 11, and the purple light irradiator 2 is installed on the outer surface of the column. The purple light irradiator 2 is used to supplement the light for the purple light irradiator 1.

[0054] Specifically, the operator places the quartz tube on the surface of the placement table 121, and then starts the auxiliary detection unit and the detection module 13 through the electrical control panel 14 to start working. At the same time, the operator also needs to start the drive motor 27 through the electrical control panel 14. After the drive motor 27 is started, its output shaft starts to rotate, and the rotation of the drive motor 27 will be synchronously transmitted to the support block 26. Since there is a close mechanical connection between the support block 26 and the power rod 24 and the L-shaped power seat 23, the rotation of the support block 26 will drive the power rod 24 and the L-shaped power seat 23 to rotate synchronously. However, since the vertical limit column 21 and the detection module 13 are restricted by the guide rail 12 and can only perform linear motion, the rotation trend of the support block 26 will be converted into a thrust for the drive sleeve 22 through the power rod 24 and the L-shaped power seat 23.

[0055] Under the action of this thrust, the driving sleeve 22 begins to slide downward on the surface of the vertical limit column 21. At the same time, the driving sleeve 22 also pushes the vertical limit column 21 and the detection module 13 thereon to move toward the side away from the middle of the operating cabinet 11. This movement process makes the detection module 13 gradually move away from the quartz tube, providing conditions for its subsequent wide-angle field of view capture. When the detection module 13 reaches the end of the movement stroke, that is, the side farthest from the middle quartz tube, the detection module 13 is restricted by the guide rail 12 and cannot continue to move. At the same time, since the detection module 13 and the vertical limit column 21 cannot move, the rotation of the bearing block 26 will elastically compress the travel spring 25, and at the same time drive the L-shaped power seat 23 to pull the driving sleeve 22 to slide on the surface of the vertical limit column 21 toward the middle. At this time, the vertical limit column 21 and the detection module 13 remain stationary, and the stopped state of the vertical limit column 21 enables the detection module 13 to perform more stable video and detection at the farthest end of the stroke, providing background information for subsequent detailed detection.

[0056] Subsequently, the rotation of the output end of the driving motor 27 continues to drive the support block 26 to rotate. At this time, the travel spring 25 has been compressed to the limit, so the rotation of the support block 26 will provide a reverse force to the L-shaped power seat 23 and the power rod 24. At this time, the support block 26 pulls the driving sleeve 22 to the middle of the vertical limit column 21 through the L-shaped power seat 23, and continuously slides it toward the bottom of the vertical limit column 21. At the same time, since the support block 26 provides an opposite force, the vertical limit column 21 as a whole will be pulled by the driving sleeve 22 to the side close to the middle of the operating cabinet 11. When the detection module 13 slides to the other stroke end, based on the above steps, the detection module 13 makes a brief stop again. This movement mode of first moving away and then approaching enables the detection module 13 to combine a wide-angle field of view and detail capture, thereby improving the comprehensiveness and accuracy of the detection.

[0057] During the entire movement process, the detection module 13 detects the end face of the quartz tube through the cooperation of the ultraviolet light illuminator 1 and the camera. The ultraviolet light illuminator 1 emits ultraviolet light to illuminate the end face of the quartz tube, and the camera captures the light to form an image. These image data will be uploaded to the electronic control panel 14 for processing and analysis. At the same time, the ultraviolet light illuminator 2 in the auxiliary detection unit provides reverse fill light for the ultraviolet light illuminator 1, thereby further improving the accuracy of the detection.

[0058] The dynamic stop detection component 2 drives the detection module 13 to effectively avoid the influence of the depth of field effect on the detection result. The depth of field effect is one of the common problems in photography and detection. It will cause different clarity of objects at different distances in the image. In the detection of the end face of the quartz tube, due to the unevenness or tiny defects on the end face, the depth of field effect will cover up these defects or cause misjudgment. However, the dynamic stop detection component 2 effectively overcomes this problem by using the movement mode of the detection module 13 that first moves away and then approaches. In the process of moving away from the quartz tube, the detection module 13 can capture a wider field of view, which provides important background information for subsequent detailed detection. In the process of approaching the quartz tube, the detection module 13 can focus on the end face of the quartz tube at a closer distance to capture more details and features. This movement mode not only improves the comprehensiveness of the detection, but also enables the detection module 13 to adapt to the unevenness of the end face of the quartz tube to capture more details and features.

[0059] Example 2, please refer to Figure 6 and Figure 7 As shown, on the basis of Example 1, a dust-proof component 3 is provided below the electric control panel 14 to prevent external dust from contaminating the quartz tube, thereby maintaining the detection accuracy. The dust-proof component 3 includes two gantries 31. The gantry 31 close to the electric control panel 14 is fixedly connected to the top of the guide rail 12, and its opening direction is downward, and the gantry 31 away from the electric control panel 14 is fixedly connected to the bottom of the guide rail 12, and its opening direction is upward. A micro cylinder 32 is fixedly connected to the side of the gantry 31 away from its opening direction, and a sliding disk 33 is installed at the output end of the micro cylinder 32.

[0060] Please refer to Figures 6 to 10 As shown, the inside of the sliding plate 33 near the electric control panel 14 is fixedly connected with an air pipe 34, and the side of the sliding plate 33 near the electric control panel 14 away from the air pipe 34 is penetrated with an arc groove 35 and a curved groove 36, the arc groove 35 is set as a curved notch shape, and the curved groove 36 is set as a circle. The side of the air pipe 34 near the arc groove 35 is fixedly connected with a diverter plate 37, and the outer surface of the diverter plate 37 is equidistantly arranged in a ring and penetrated with second output grooves 39, and the middle part of the diverter plate 37 is penetrated with a first output Groove 38, the outer surface of the diverter plate 37 near the arc groove 35 is arranged with inclined grooves 310 in a circular shape and at equal intervals, a filter screen 311 is installed inside the sliding plate 33 near the detection module 13, and the electric control panel 14 electrically controls the start and close of the two micro cylinders 32. The side of the air pipe 34 away from the sliding plate 33 is fixedly connected to the fan, and the fan is installed on the top of the auxiliary detection unit, and the outer surface of the air pipe 34 is sleeved with an external tank chain, and the two ends of the external tank chain are respectively installed on the auxiliary detection unit and the outer surface of the sliding plate 33.

[0061] It should be noted that the lengths of the air pipe 34 and the external tank chain are greater than the travel length of the sliding plate 33, the overall size of the arc groove 35 is greater than the outer wall size of the quartz piece, and the overall size of the curved groove 36 is smaller than the inner wall size of the quartz piece.

[0062] Specifically, after the operator places the quartz tube on the surface of the placement table 121, the operator starts the fan through the electric control panel 14. At this time, the fan transports pure air to the inside of the sliding disk 33 through the air pipe 34. The pure air is divided into two parts inside the sliding disk 33: one part of the air will enter the outer edge of the sliding disk 33 through the second output groove 39, and finally be discharged from the arc groove 35; and the other part of the air will be directly discharged through the first output groove 38. Since the overall size of the first output groove 38 is smaller than the inner wall of the quartz tube, and the overall size of the arc groove 35 is larger than the outer wall of the quartz tube, this design ensures that the pure air will not directly act on the surface of the quartz tube, but form a specific airflow path.

[0063] Based on Bernoulli's principle, the flow of air will generate negative pressure at the arc groove 35 and the curved groove 36. The air flow through the arc groove 35 will form a negative pressure area between the quartz tube and it, thereby taking away the dust through the negative pressure. Similarly, the air passing through the first output groove 38 and located inside the quartz tube will also form a negative pressure area between it and the inner wall of the quartz tube, taking away the dust on the inner wall. As the air flows, negative pressure will also be generated at both ends of the quartz tube, and the dust at both ends will be taken away.

[0064] During this process, not all of the air passing through the first output slot 38 enters the interior of the quartz tube, because the kinetic energy of the gas is continuously lost during the transmission process, and there is friction, and the gas that loses kinetic energy will be pushed by the subsequent gas and begin to float, so part of the gas will stay near the inclined slot 310. As the air continues to flow, this part of the gas is also pulled by the negative pressure and forms a gas with a stable shape similar to a spiral trend under the guidance of the inclined slot 310. The formation of this spiral gas is due to the special design of the inclined slot 310. Due to the inclined setting of the inclined slot 310, the gas that originally flows in a straight line generates a rotational momentum when passing through, thereby forming a spiral shape. This spiral gas not only has a stable shape, but also can continuously act on the inner wall of the quartz tube to prevent the gas from deviating from the center of the first output slot 38 and escaping to the surroundings, thereby improving the cleaning efficiency.

[0065] It should be noted that when the gas passes through, it needs to smoothly enter the inner wall and outside of the quartz tube to form a negative pressure area. If the spiral gas is designed from the beginning, it will hinder the smooth flow of air, thereby affecting the formation of negative pressure and the dust cleaning effect. The subsequent formation of spiral gas under the guidance of the inclined groove 310 further optimizes the airflow pattern and improves the cleaning efficiency on the basis of ensuring air flow and negative pressure formation.

[0066] Finally, the gas acts on the surface of the filter 311 at the other end of the quartz tube. Under the interception of the filter 311, the air begins to drift, while the dust and pollutants are intercepted by the filter 311. At the same time, the filter 311 can effectively collect the dust and pollutants carried away by the gas to prevent them from polluting the quartz tube or the detection environment again. Subsequently, the operator electrically turns off the fan through the electrical control panel 14, and starts the micro-cylinder 32 to make the output end of the micro-cylinder 32 contract, and drives the sliding disk 33 to move toward the side away from the opening direction of the detection module 13. At this time, the sliding disk 33 no longer blocks the detection module 13 from detecting the quartz tube. At this time, the operator can control the detection module 13 to start and detect the end face of the quartz tube through the electrical control panel 14.

[0067] It should be noted that since the filter 311 is installed inside the sliding disk 33, when the filter 311 has a low dust interception ability, the operator can replace the filter 311 with a new one. This design not only facilitates the operator's maintenance and use, but also ensures the continuity and accuracy of the detection.

[0068] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "including one..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0069] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
