Description

Technical Field

[0001] This utility model relates to the field of size measurement technology, and in particular to an automatic measuring device for glass tube size. Background Technology

[0002] During or after the production of glass tubes, dimensional measurements are required. These measurements mainly include diameter, length, and ovality. Among these, diameter and length measurements are indispensable parts of quality control.

[0003] Currently, the common methods for measuring the diameter of glass tubes are calipers or laser diameter gauges. When using calipers, the measurement is taken manually by hand and the reading is recorded. A laser diameter gauge uses laser technology to measure diameter; it emits a laser beam and receives the emitted light to measure the diameter of the glass tube. In practice, manual assistance is required during the measurement process. When measuring the length of glass tubes, calipers, micrometers, or laser rangefinders are commonly used. The methods for measuring the length of glass tubes are similar to those for measuring the diameter, also requiring manual assistance.

[0004] There are certain limitations to using manual assistance to measure the dimensions of glass tubes. The measurement process may damage the glass tube, resulting in poor accuracy and low efficiency.

[0005] In the process of realizing this utility model, the inventors discovered that the prior art has at least the following problems:

[0006] The accuracy and efficiency of measuring the dimensions of glass tubes are low. Utility Model Content

[0048] To illustrate the technical solution described in this utility model, specific embodiments are described below, showing only the parts related to the embodiments of this utility model.

[0049] Example 1:

[0050] like Figure 1-4 As shown, this utility model provides an automatic glass tube size measuring device, including: a feeding mechanism 1, a conveying mechanism 2, a diameter measuring mechanism 3, a length measuring mechanism 4, and a discharging mechanism 5; the conveying mechanism 2 is located below the feeding mechanism 1 and is used to receive the glass tubes sequentially fed by the feeding mechanism 1 and to convey the glass tubes; the diameter measuring mechanism 3 is located on the conveying path of the conveying mechanism 2 and is used to measure the diameter of the glass tube; the length measuring mechanism 4 is located on the conveying path of the conveying mechanism 2 and is used to measure the length of the glass tube when the conveying mechanism 2 conveys the glass tube to the corresponding position below the length measuring mechanism 4; the discharging mechanism 5 is correspondingly arranged with the length measuring mechanism 4 and is used to remove the glass tube for discharging after the length measuring mechanism 4 has completed the length measurement of the glass tube.

[0051] Specifically, the automatic measuring device described in this embodiment includes a conveying mechanism 2, a loading mechanism 1, a unloading mechanism 5, a diameter measuring mechanism 3, and a length measuring mechanism 4. The loading mechanism 1 is used to load glass tubes into the conveying mechanism 2. The conveying mechanism 2 is used to receive the glass tubes loaded by the conveying mechanism 2 and transport the glass tubes along the conveying path to ensure that the glass tubes can be transported in an orderly manner to the subsequent inspection station.

[0052] Both the diameter measuring mechanism 3 and the length measuring mechanism 4 are located on the conveying path of the conveying mechanism 2. The diameter measuring mechanism 3 is used to measure relevant data about the diameter of the glass tube (specifically, it may include the diameter and ellipticity). After the diameter measuring mechanism 3 completes its measurement, the glass tube continues to be conveyed by the conveying mechanism 2 to the length measuring mechanism 4, where the length measuring mechanism 4 measures the length of the glass tube. The unloading mechanism 5 is positioned corresponding to the length measuring mechanism 4. After the length of the glass tube is measured, the unloading mechanism 5 removes the glass tube to complete the unloading process.

[0053] The automatic measuring device described in this embodiment can automatically complete the feeding, conveying, measuring and unloading operations of glass tubes. It can automatically measure the size of glass tubes without manual intervention, thus improving measurement efficiency and accuracy.

[0054] Below, we will combine Figure 1-4 The automatic glass tube size measuring device described in this embodiment will be described in detail.

[0055] The automatic measuring device described in this embodiment includes a feeding mechanism 1, a conveying mechanism 2, a diameter measuring mechanism 3, a length measuring mechanism 4, and a discharging mechanism 5. Specifically, the feeding mechanism 1, the conveying mechanism 2, the diameter measuring mechanism 3, the length measuring mechanism 4, and the discharging mechanism 5 can all be fixedly mounted on the same supporting device. In this embodiment, the supporting device is not specifically described.

[0056] As an optional implementation method, such as Figure 2 As shown, the feeding mechanism 1 includes a feeding platform 11, a feeding rotating shaft 12, a release structure, and a feeding baffle 15. The feeding platform 11 is used to place multiple glass tubes. The feeding rotating shaft 12 is located above the feeding platform 11 and can rotate to arrange the glass tubes neatly for conveying. The release structure is set through the feeding platform 11 and can swing to block or release the glass tubes and convey them sequentially. The feeding baffle 15 is located at the end of the feeding platform 11 and is used to block the glass tubes so that they fall into the conveying mechanism 2.

[0057] Specifically, the loading platform 11 serves as a table for placing glass tubes, capable of supporting multiple glass tubes to facilitate subsequent glass tube transport and make the transport process more orderly and convenient. The loading platform 11 is designed with an incline to allow the glass tubes to roll freely. The loading shaft 12, located above the loading platform 11, has a rotating function, specifically clockwise. After the glass tubes are placed on the loading platform 11, the loading shaft 12 rotates to adjust and arrange the glass tubes neatly, ensuring that only one layer of glass tubes remains on the loading platform 11, facilitating their subsequent placement into the conveying mechanism 2. It should be noted that the loading shaft 12 is driven by a drive mechanism, and its rotation speed can be adjusted according to actual needs to ensure the glass tubes are stably and orderly arranged and transported. The drive mechanism is not described in detail in this embodiment. In addition, the feeding shaft 12 in this embodiment is a hexagonal shaft, and the tip of the feeding shaft 12 is made of rubber, which can increase the friction between the shaft and the glass tube, prevent the glass tube from slipping or becoming misaligned during rotation, and also avoid damage to the glass tube when adjusting it.

[0058] The release structure is located below the loading platform 11 and can swing to block or release the glass tubes, conveying them sequentially. In this embodiment, the main function of the release structure is to release or block the glass tubes. By swinging, the release structure can control the conveying rhythm of the glass tubes, achieving the purpose of conveying the glass tubes sequentially, avoiding confusion caused by simultaneous conveying of glass tubes, ensuring the accuracy of the conveying tubes, and improving the stability of the loading mechanism 1.

[0059] More specifically, such as Figure 2 As shown, the release structure includes a first release hook group 13 and a second release hook group 14, which are staggered in the conveying direction of the glass tube. The first release hook group 13 includes a first release shaft 131 and a plurality of first release hooks 132, which are evenly distributed on the first release shaft 131. The second release hook group 14 includes a second release shaft 141 and a plurality of second release hooks 142, which are evenly distributed on the second release shaft 141.

[0060] In this embodiment, the first discharge hook group 13 and the second discharge hook group 14 can respectively release and block the glass tube by swinging. The first discharge hook group 13 and the second discharge hook group 14 are staggered in the conveying direction of the glass tube, which can avoid interference between the first discharge hook group 13 and the second discharge hook group 14 during the swinging process.

[0061] The first feeding hook group 13 includes a first feeding shaft 131 and a plurality of first feeding hooks 132, which are evenly distributed on the first feeding shaft 131. The second feeding hook group 14 includes a second feeding shaft 141 and a plurality of second feeding hooks 142, which are evenly distributed on the second feeding shaft 141.

[0062] like Figure 2 As shown, the first feeding shaft 131 can drive multiple feeding hooks to swing under the action of the driving component, and the second feeding shaft 141 can also drive multiple feeding hooks to swing under the action of the driving component. Furthermore, the swing angle and swing speed of the first feeding shaft 131 and the second feeding shaft 141 are also controlled by the driving component, thereby improving the accuracy and stability of glass tube conveying. The driving component is not described in detail in this embodiment.

[0063] When the first discharge hook group 13 is in the releasing state, multiple first discharge hooks 132 will swing under the action of the first discharge shaft 131, and the multiple first discharge hooks 132 will swing to below the loading platform 11, outside the glass tube's conveying path, and will not obstruct the glass tube's conveying. When the first discharge hooks 132 are in the blocking state, multiple first discharge hooks 132 will extend into the platform surface of the loading platform 11, into the glass tube's conveying path, and block the glass tube. The second discharge hooks 142 in the second discharge hook group 14 are the same as the first discharge hooks 132 in the first discharge hook group 13.

[0064] It should be noted that, in order for the first discharge hook 132 and the second discharge hook 142 to release or block the glass tube on the loading platform 11, the loading platform 11 on the swing path of the first discharge hook 132 and the second discharge hook 142 is set as a hollow structure, which facilitates the position movement of the first discharge hook 132 and the second discharge hook 142 and avoids motion interference between the first discharge hook 132, the second discharge hook 142 and the loading platform 11.

[0065] The first feeding hook group 13 and the second feeding hook group 14 are used to release or block the glass tube respectively. After the first feeding hook group 13 releases the glass tube, the released glass tube will be blocked by the second hook group. The second feeding hook group 14 will release the glass tube when it is needed to enter the conveying mechanism 2 later.

[0066] In this embodiment, the arrangement of the first discharge hook group 13 and the second discharge hook group 14 ensures the correct release of the glass tubes and effectively controls the conveying rhythm of the glass tubes, ensuring that the glass tubes enter the conveying mechanism 2 in a predetermined order and rhythm. After the first discharge hook group 13 releases the glass tube, the second discharge hook group 14 immediately blocks it, preventing the accumulation and disorder of the glass tubes. When a glass tube needs to enter the conveying mechanism 2, the second discharge hook group 14 accurately releases the corresponding glass tube, ensuring that the glass tube enters the conveying mechanism 2 accurately. This improves the accuracy and stability of glass tube conveying and enhances the automation level and efficiency of the automatic measuring device.

[0067] In addition, such as Figure 2 As shown, the feeding mechanism 1 also includes a feeding baffle 15, which is located at the end of the feeding platform 11 and is used to block the glass tube, causing it to fall into the conveying mechanism 2. In this embodiment, the feeding baffle 15 serves as a barrier, blocking the glass tube at the end of the feeding platform 11 so that the glass tube can be accurately placed into the conveying mechanism 2. At the same time, the feeding baffle 15 has a simple structure, is easy to operate, and is easy to maintain and adjust, improving the reliability and practicality of the automatic measuring device.

[0068] In this embodiment, the feeding mechanism 1 can efficiently complete the arrangement and conveying of glass tubes, providing a stable supply of glass tubes for subsequent measurement steps.

[0069] As an optional implementation, the conveying mechanism 2 is correspondingly disposed at the bottom of the loading baffle 15. For example... Figure 1-4 As shown, the conveying mechanism 2 includes multiple drive wheels 21 arranged sequentially with equal spacing, used to convey the glass tube along a predetermined conveying path. Specifically, the conveying mechanism 2 also includes a driving component, which drives the drive wheels 21 to convey the glass tube. The driving component is not specifically described in this embodiment.

[0070] In this embodiment, all of the multiple drive wheels 21 can be driving wheels, or some can be driving wheels and some can be driven wheels. When all of the drive wheels 21 are driving wheels, each drive wheel 21 is directly driven by a driving component. This arrangement provides stronger driving force, ensuring that the glass tube does not stop or deviate during transport due to excessive resistance. When some are driving wheels and some are driven wheels, the number of driving components can be reduced while maintaining transport efficiency, thus lowering the complexity and cost of the equipment. It should be noted that both of these different methods can be adjusted according to actual needs to adapt to different working environments and measurement requirements.

[0071] More specifically, in this embodiment, the drive wheel 21 is V-shaped to facilitate stable transport of the glass tube. Additionally, the drive wheel 21 can be made of rubber to increase friction with the glass tube and prevent it from slipping or rolling during transport.

[0072] As an optional implementation method, such as Figure 3 As shown, the diameter measuring mechanism 3 includes a mounting ring 31 and multiple diameter measuring components 32; each diameter measuring component 32 includes a first vision camera 321 and a first light source 322, the first vision camera 321 and the first light source 322 are arranged opposite to each other on the mounting ring 31, and the first vision camera 321 is aligned with the center of the mounting ring 31; the glass tube conveyed by the conveying mechanism 2 passes through the center of the mounting ring 31 and is measured by the multiple diameter measuring components 32.

[0073] Specifically, the diameter measuring mechanism 3 mainly consists of two parts: a mounting ring 31 and multiple diameter measuring components 32. The mounting ring 31 serves to support and position the diameter measuring components 32, which are able to measure the diameter of the glass tube being conveyed on the conveying mechanism 2 on the mounting ring 31.

[0074] Each diameter measuring component 32 includes a first vision camera 321 and a first light source 322 correspondingly mounted on the mounting ring 31. The diameter measuring component 32 measures the glass tube in cooperation with the first vision camera 321 and the first light source 322. The focusing center of each first vision camera 321 is located at the center of the mounting ring 31. This arrangement allows each diameter measuring component 32 to be aligned with the center from different angles, ensuring the accuracy of the obtained diameter.

[0075] More specifically, during the conveying process of the glass tube, the glass tube passes through the center of the mounting ring 31. When the glass tube passes the center, multiple diameter measuring components 32 located around the mounting ring 31 can measure the diameter of the glass tube to ensure the accuracy of the obtained diameter. It should be noted that, in order to ensure the accuracy of the measurement of the glass tube at the center, the position of the mounting ring 31 is adjusted so that the center of the mounting ring 31 is within 1-2 cm behind a certain drive wheel 21 in the conveying mechanism 2, so as to reduce the error caused by the vibration of the conveying mechanism 2 during measurement.

[0076] As an optional implementation method, such as Figure 4 As shown, the length measuring mechanism 4 includes a reference component 41 and two length measuring components 42; the two length measuring components 42 are located above the reference component 41 and are respectively aligned with the first end and the second end of the reference component 41; the reference component 41 and the glass tube being transported by the transport component are located on the same plane and in the same direction.

[0077] Specifically, the reference component 41 and two length measuring components 42 in the length measuring mechanism 4 cooperate with each other to measure the length of the glass tube. The reference component 41 is fixedly disposed below the two length measuring components 42, and the length measuring components 42 are respectively aligned with the two ends of the reference component 41. The two length measuring components 42 are used to measure the length of the glass tube relative to the first end and the second end of the reference component 41, respectively.

[0078] When the glass tube is conveyed along its conveying path by the conveying mechanism 2, it will be conveyed to the side of the reference component 41. The two length measuring components 42 will record the positional relationship between the glass tube and the two ends of the reference component 41, thereby calculating the length of the glass tube. Using two length measuring components 42 for length measurement can ensure the accuracy of the length measurement, and since the reference component 41 and the glass tube are on the same plane, the measurement error caused by position deviation is reduced. In this embodiment, the length measuring component 42 includes a second vision camera 421 and a second light source 422 arranged opposite to each other. The second vision camera 421 and the second light source 422 cooperate to acquire images of the end of the glass tube. Subsequently, image processing technology is used to obtain the relative position of the glass tube and the reference component 41, and then the length of the glass tube is calculated to improve the accuracy and efficiency of the measurement.

[0079] As an optional implementation method, such as Figure 4 As shown, the feeding mechanism 5 includes a first pushing structure 51, a second pushing structure 52, and a receiving platform 53. The first pushing structure 51 is located below the length measuring mechanism 4. After the length measuring mechanism 4 completes the measurement, it pushes the glass tube upward. The second pushing structure 52 is located diagonally below the length measuring mechanism 4. After the first pushing structure 51 pushes the glass tube out, the second pushing structure 52 is used to push the glass tube to the receiving platform 53.

[0080] Specifically, the unloading mechanism 5 includes a first pushing structure 51, a second pushing structure 52, and a receiving platform 53. After the glass tube completes the length measurement in the length measuring mechanism 4, the glass tube will be pushed to the receiving platform 53 under the action of the first pushing structure 51 and the second pushing structure 52, and the glass tube will be received on the receiving platform 53.

[0081] More specifically, such as Figure 4As shown, the first pushing structure 51 is located below the length measuring mechanism 4. After the length measuring mechanism 4 completes the length measurement of the glass tube, the first pushing structure 51 will push upwards, ejecting the glass tube from its current position. The second pushing structure 52 is located diagonally below the length measuring mechanism 4. After the first pushing structure 51 ejects the glass tube, the second pushing structure 52 begins to work, pushing the glass tube from the first pushing structure 51 to the receiving table 53, completing the glass tube unloading operation. During the coordinated operation of the first pushing structure 51 and the second pushing structure 52, the precise coordination between the two pushing structures ensures that the glass tube can be smoothly and steadily pushed from the length measuring mechanism 4 to the receiving table 53.

[0082] Among them, such as Figure 4 As shown, the first pushing structure 51 includes a first pushing main rod (not shown in the figure) and multiple first pushing groups 511. The multiple first pushing groups 511 are all fixedly connected to the first pushing main rod, and the multiple first pushing groups 511 are synchronously displaced under the action of the first pushing main rod. The first pushing group 511 includes a first pushing rod 512 and a first pushing plate 513. The first pushing plate 513 is connected to the first pushing rod 512 through a first rotating rod 514.

[0083] Specifically, multiple first pusher groups 511 are all connected to a first pusher main rod, which is driven by a drive component to rise or fall, thereby causing the multiple first pusher groups 511 to move synchronously. In each first pusher group 511, one end of the first pusher rod 512 is fixedly connected to the first pusher main rod, and the other end is connected to the first pusher plate 513 via a first rotating rod 514, allowing the first pusher plate 513 to rotate around the first rotating rod 514. To ensure uniform movement of the first pusher plate 513, only one rotating rod is provided in the pusher group.

[0084] It should be noted that the first rotating rod 514 is also controlled by a driving component, which is not specifically described in this embodiment. The first pusher plate 513 is designed with an arc shape, which facilitates the ejection of the glass tube while protecting it, and also facilitates subsequent cooperation with the second pusher structure 52 to eject the glass tube into the receiving platform 53.

[0085] The working principle of the first pushing structure 51 is as follows: In the initial state, the opening of the first pushing plate 513 faces the top. When the first pushing main rod moves upward, multiple first pushing groups 511 move synchronously. The first pushing plate 513 contacts the glass tube and pushes the glass tube upward. After being pushed out, the first pushing plate 513 will rotate under the action of the first rotating rod 514. At the same time, the first rotating rod 514 drives the first pushing plate 513 to rotate, so that the opening of the first pushing plate 513 faces obliquely upward, which facilitates the subsequent second pushing structure 52 to push the glass tube to the receiving platform 53.

[0086] like Figure 4 As shown, the second pushing structure 52 includes a second pushing main rod (not shown in the figure) and multiple second pushing groups 521. The multiple second pushing groups 521 are all fixedly connected to the second pushing main rod, and the multiple second pushing groups 521 are synchronously displaced under the action of the second pushing main rod. The second pushing group 521 includes a second pushing rod 522 and a second pushing plate 523. The second pushing plate 523 is connected to the second pushing rod 522 through a second rotating rod 524.

[0087] Specifically, multiple second pusher groups 521 are all connected to a second pusher main rod, which is driven by a drive component to rise or fall, thereby causing the multiple second pusher groups 521 to move synchronously. In each second pusher group 521, one end of the second pusher rod 522 is fixedly connected to the second pusher main rod, and the other end is connected to the second pusher plate 523 via a second rotating rod 524, allowing the second pusher plate 523 to rotate around the second rotating rod 524. To ensure uniform movement of the second pusher plate 523, only one rotating rod is provided in the pusher group.

[0088] It should be noted that the second rotating rod 524 is also controlled by a driving component, which is not specifically described in this embodiment. The second pusher plate 523 is designed with an arc shape to facilitate the ejection of the glass tube while protecting it, and to eject the glass tube into the receiving platform 53.

[0089] The working principle of the second pushing structure 52 is as follows: In the initial state, the opening of the second pushing plate 523 faces obliquely upward. When the second pushing main rod moves upward, multiple second pushing groups 521 move synchronously. The second pushing plate 523 will contact the glass tube in the first pushing structure 51 and push the glass tube obliquely upward. After being pushed out, the second pushing plate 523 will rotate under the action of the second rotating rod 524. At the same time, the second rotating rod 524 drives the second pushing plate 523 to rotate, so that the opening of the second pushing plate 523 faces the receiving table 53, pushing the glass tube out to the receiving table 53.

[0090] It should be noted that in this embodiment, the first pushing group 511 and the second pushing group 521 in the first pushing structure 51 are staggered to avoid interference during movement. Furthermore, the working sequence of the first pushing structure 51 and the second pushing structure 52 is that the first pushing structure 51 works first, followed by the second pushing structure 52, ejecting the glass tube according to the predetermined order. In this embodiment, the precise coordination of the actions of the first pushing structure 51 and the second pushing structure 52 ensures the smoothness and stability of the entire feeding process, achieving efficient pushing of the glass tube and improving the efficiency of pushing the glass tube.

[0091] As an optional implementation method, such as Figure 4 As shown, the unloading mechanism 5 also includes a receiving frame 54, which is located at the bottom of the receiving table 53 and is used to collect the glass tubes conveyed on the receiving table 53. Specifically, the receiving frame 54 cooperates with the receiving table 53 to collect the glass tubes.

[0092] The receiving platform 53 is designed with an incline. Multiple receiving openings 531 and multiple receiving baffles 532 are arranged on the platform surface along the rolling direction of the glass tube. The receiving baffles 532 are located behind the receiving openings 531, and are correspondingly positioned to the receiving openings 531. Receiving frames 54 are located at the bottom of the receiving platform 53, and their number and position also correspond to the receiving openings 531 and receiving baffles 532. The function of the receiving baffles 532 is to block the glass tubes; the blocked glass tubes will fall downwards through the receiving openings 531 into the receiving frames 54. It should be noted that each different receiving frame 54 is used to store glass tubes of different test grades. For example, glass tubes with lower test result grades will be stored in the receiving frame 54 at the bottom end of the receiving platform 53, while glass tubes with higher test result grades will be stored in the receiving frame 54 at the front end of the receiving platform 53. In addition, water can be stored in the receiving box 54 to cushion the falling glass tubes and ensure their integrity.

[0093] In addition, the receiving baffle 532 is driven by a drive component. When the glass tube does not need to fall into the corresponding receiving frame 54, the receiving baffle 532 will open, allowing the glass tube to move backward along the direction of the receiving platform 53 and fall into the corresponding receiving frame 54 under the action of other receiving baffles 532, so as to ensure the accuracy and stability of the collection.

[0094] More specifically, a corresponding sensor can be installed in the conveying mechanism 2. When the glass tube is conveyed to a certain position in the conveying mechanism 2, an electrical signal can be emitted to cause the feeding mechanism 1 to feed the glass tube back into the conveying mechanism 2. Of course, sensors can also be installed in the feeding mechanism 1, the diameter measuring mechanism 3, the length measuring mechanism 4, and the unloading mechanism 5 to ensure the accurate operation of the automatic measuring device. These details will not be elaborated in this embodiment.

[0095] The working principle of the automatic glass tube size measuring device described in this embodiment is as follows:

[0096] Multiple glass tubes are stacked on the loading platform 11 of the loading mechanism 1. The glass tubes are arranged in an orderly manner under the action of the loading shaft 12. Then, the orderly arranged glass tubes are conveyed in sequence under the action of the directional structure. The conveyed glass tubes fall into the conveying mechanism 2 under the action of the loading baffle 15 at the end of the loading platform 11.

[0097] The conveying mechanism 2 conveys the glass tube. The diameter measuring mechanism 3 and the length measuring mechanism 4 in the conveying direction of the conveying mechanism 2 measure the size of the glass tube. After the measurement is completed, the glass tube is unloaded.

[0098] During the unloading process, the first pushing structure 51 pushes the glass tube on the conveying mechanism 2 upward, and then the second pushing mechanism pushes it diagonally upward, pushing the glass tube in the first pushing structure 51 out, so that the glass tube falls onto the receiving platform 53 and is collected in the receiving frame 54 at the bottom of the receiving platform 53.

[0099] The automatic measuring device described in this embodiment can automatically complete the feeding, conveying, measuring and unloading operations of glass tubes. It can automatically measure the size of glass tubes without manual intervention, thus improving measurement efficiency and accuracy.

[0100] The embodiment is merely a special case and does not indicate that this utility model is implemented in such a way.

[0101] Example 2

[0102] The difference between Embodiment 2 and Embodiment 1 is that Embodiment 1 describes the measurement of a single glass tube using the diameter measuring mechanism 3 and length measuring mechanism 4, with the corresponding components installed. However, in Embodiment 2, the number of corresponding components can be increased to measure multiple glass tubes simultaneously. The following will be discussed in conjunction with... Figures 5-7 The section elaborates on the two glass tubes in relation to increasing the number of corresponding components.

[0103] When loading materials, such as Figure 5 As shown, a feeding baffle 15 can be added, and a feeding trough can be opened in the conveying direction of the feeding platform 11. A conveying mechanism 2 can be added directly below the feeding trough. After the feeding baffle 15 blocks the glass tube, the glass tube will fall from the feeding trough into the conveying mechanism 2 below, and the conveying mechanism 2 will transport the glass tube.

[0104] like Figures 5-6As shown, in the added conveying mechanism 2, a diameter measuring mechanism 3 and a length measuring mechanism 4 are added along the conveying direction of the conveying mechanism 2. The diameter measuring mechanism 3 and the length measuring mechanism 4 measure the diameter and length of the glass tube in the conveying direction of the conveying mechanism 2. It should be noted that the added conveying mechanism 2 is arranged parallel to the conveying mechanism 2 described in Embodiment 1. Therefore, the added diameter measuring mechanism 3 and the length measuring mechanism 4 are also arranged parallel to each other.

[0105] When feeding materials, such as Figure 7 As shown, a first pushing structure 51 is added to push out the measured glass tube, and finally the second pushing structure 52 pushes the glass tube to the receiving platform 53 to complete the unloading of the glass tube.

[0106] Because additional components are added to enable the measurement of multiple glass tubes within a single automatic measuring device, care must be taken during the addition process to avoid motion interference with other components. The timing of these components can be controlled during loading and unloading.

[0107] The automatic glass tube size measuring device described in Example 2 can automatically measure the size of glass tubes without manual intervention, improving measurement efficiency and accuracy, and further improving testing efficiency. It is suitable for scenarios requiring large-scale measurement.

[0108] The above description is merely a preferred embodiment of the present utility model. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the present utility model. Furthermore, under the teachings of the present utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present utility model. Therefore, the present utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of the present utility model.
