Description

Technical Field

[0001] This utility model relates to the field of glass tube conveying technology, specifically a vertical glass tube feeding mechanism with buffer and shock absorption. Background Technology

[0002] In the medical field, glass tubes are core components of medical devices such as syringes, infusion tubes, and test tubes. Their production process has extremely high requirements for cleanliness, integrity, and delivery stability. Medical glass tubes are mostly made of high-strength materials such as borosilicate glass. However, due to their thin walls and high brittleness, any slight vibration or impact during delivery may cause cracks or damage, which may lead to contamination or functional failure of medical supplies. In severe cases, it may affect the safety of clinical use. Therefore, the vertical feeding mechanism of medical-grade glass tubes must meet multiple stringent standards such as aseptic environment adaptation, zero-breakage delivery, and precise positioning.

[0003] In existing vertical feeding technologies for medical glass tubes, common mechanisms mostly follow the industrial conveyor belt transport mode. Vertical transport is achieved through a combination of fixed supports and buffer pads. A motor-driven conveyor roller rotates the conveyor belt, and the glass tubes are placed in racks fixed to the conveyor belt, then transported vertically to subsequent stations such as sterilization and filling. Some equipment uses stainless steel supports or adds surface finishing to meet medical cleanliness requirements. However, in terms of buffering and shock absorption structure design, fixed-height rubber pads or unidirectional springs are still commonly used, without specific optimization for the unique brittle characteristics of medical glass tubes. However, existing technologies have some problems in medical applications. Traditional buffer structures cannot effectively absorb the combined vibrations caused by start-stop inertia and conveyor belt shaking during vertical transport. Medical glass tubes are prone to micro-cracks due to repeated impacts during transport, leading to an increased breakage rate. Therefore, we propose a vertical feeding mechanism for glass tubes with buffering and shock absorption. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5This embodiment provides a technical solution: a vertical glass tube feeding mechanism with buffer and shock absorption, including a support 1. A microcontroller 14 is provided on the right side of the support 1. The input end of the microcontroller 14 is electrically connected to an external power source. A feeding assembly is provided inside the support 1. A glass tube placement rack 12 is installed at the front end of the feeding assembly. The feeding assembly includes a conveyor roller 3 and a conveyor belt 4. The conveyor rollers 3 are rotatably connected between the left and right inner walls of the support 1. The conveyor rollers 3 are connected to each other through the conveyor belt 4. The glass tube placement rack 12 is fixedly connected to the front side of the front belt body of the conveyor belt 4. A servo motor 5 is installed on the right side of the conveyor belt 4. The output shaft of the servo motor 5 is fixedly connected to the center of the right end face of the adjacent left conveyor roller 3. The input end of the servo motor 5 is electrically connected to a microcontroller 14. The output end of the microcontroller 14 has symmetrically distributed mounting plates 6 on the left side of the bracket 1. Each mounting plate 6 has a groove 7 in the middle, and a slide block 8 is slidably connected inside each groove 7. Each slide block 8 has an infrared sensor 9 on its left side, which is bidirectionally electrically connected to the microcontroller 14. The right side of the bracket 1 has symmetrically distributed reflectors 11, which cooperate with the adjacent infrared sensors 9 on the left. Each slide block 8 has a tightening screw 10 threaded to its left rear end, and the right end of the tightening screw 10 contacts the left side of the adjacent mounting plate 6 on the right. The upper part of the glass tube placement rack 12 has a glass tube placement ring 13. The conveyor belt 4 carries the glass tube placement rack 12 in a cyclical manner. When the glass tube placement rack 12 is not within the detection range... Infrared light emitted by infrared sensor 9 travels through the air to reflector 11 on the right side. Reflector 11 is made of stainless steel and reflects the infrared light back to infrared sensor 9. Infrared sensor 9 continuously receives infrared light, forming a stable detection loop. When glass tube holder 12 moves with conveyor belt 4 to the detection area between infrared sensor 9 and reflector 11, the solid structure of glass tube holder 12 blocks the transmission path of infrared light, causing a change in the transmission path. Immediately afterward, it sends an electrical signal indicating "obstacle detected" to microcontroller 14. After receiving the signal change from infrared sensor 9, microcontroller 14 executes preset control logic: it sends a stop command to servo motor 5 to stop servo motor 5. When the conveyor belt 4 loses power, the glass tube holder 12 stops moving and is precisely positioned within the detection range of the infrared sensor 9, i.e., the preset target position. At this point, the user can place the glass tube inside the glass tube holder 12. Then, the user manually operates the microcontroller 14 to make the servo motor 5 run, and the conveyor roller 3 rotates again. The conveyor belt 4 drives the glass tube holder 12 to move again. When the glass tube holder 12 moves to the detection area between the upper infrared sensor 9 and the upper reflector 11, the solid structure of the glass tube holder 12 blocks the transmission path of the infrared light, causing a change in the transmission path of the infrared light. Immediately afterward, it sends an electrical signal of "obstacle detected" to the microcontroller 14. After receiving the signal change from the upper infrared sensor 9, the microcontroller 14...The system executes preset control logic: a stop command is sent to servo motor 5, causing servo motor 5 to stop operating, conveyor belt 4 to lose power, and glass tube placement rack 12 to stop moving. At this point, the user can remove the glass tube. The slide block 8 can slide within the groove 7 of the mounting plate 6 and is fixed in position by tightening screw 10, thereby adjusting the height of the infrared sensor 9 to meet the requirements of the glass tube loading position for precise positioning. It also includes a buffer assembly 2.

[0023] Buffer assembly 2 includes rubber strips 21, slide rails 22, and rubber sleeves 23. Rubber strips 21 are respectively disposed on the left and right sides of the bracket 1, and slide rails 22 are respectively disposed on the left and right sides of the glass tube placement rack 12. The glass tube placement rack 12 is configured to cooperate with the adjacent upper rubber strips 21. Rubber sleeves 23 are disposed on the bottom wall of the glass tube placement rack 12. Buffer assembly 2 also includes an adjusting plate 24, an adjusting groove 25, a limiting bracket 26, and a tightening screw 27. The adjusting plate 24 is disposed at the front end of the glass tube placement rack 12, and an adjusting groove 25 is formed in the middle of the adjusting plate 24. The limiting frame 26 is slidably connected to the inside of the adjusting groove 25. The rear end of the limiting frame 26 is fixedly connected to the upper end of the rubber sleeve 23. A tightening screw 27 is threadedly connected to the front right end of the limiting frame 26. The rear end of the tightening screw 27 contacts the front side of the adjusting plate 24. The glass tube is placed vertically in the glass tube placement ring 13 of the glass tube placement rack 12, so that the lower end of the glass tube is inserted into the inside of the rubber sleeve 23. The elastic material of the rubber sleeve 23 has a certain deformation capacity. When inserted, it can slightly wrap around the lower end of the glass tube to form a flexible fixation, which ensures that the glass tube is transported. The process is stable and avoids damage caused by hard contact. The elastic body of the rubber sleeve 23 can absorb vertical vibration. When the conveyor belt 4 starts or stops, or when the glass tube placement rack 12 moves, the rubber sleeve 23 buffers the vertical impact of the glass tube through deformation, reducing the cracking or breakage of the glass tube caused by vibration. Subsequently, the servo motor 5 starts after receiving the electrical signal from the microcontroller 14. Its output shaft drives the left conveyor roller 3 to rotate, which drives all the conveyor rollers 3 to operate synchronously through the conveyor belt 4. When the conveyor belt 4 is running, the glass tube placement rack 12 moves vertically to transport the glass tube. When the glass tube placement rack 12 moves to the designated position, the slide rails 22 on the left and right sides of the glass tube placement rack 12 cooperate with the rubber strips 21 on the left and right sides of the bracket 1. When the glass tube placement rack 12 moves, the slide rails 22 contact the rubber strips 21. The elasticity of the rubber strips 21 absorbs lateral vibration and prevents the glass tube from being damaged by collision due to left and right swaying. The adjustment groove 25 on the adjustment plate 24 can slide the limit frame 26 to drive the rubber sleeve 23 to extend and retract, thereby adjusting the height of the rubber sleeve 23. After adjustment, the limit frame is fixed by tightening screw 27 to accommodate glass tubes of different heights and improve the safety of glass tube transportation.

[0024] The working principle of the vertical glass tube feeding mechanism with buffer and shock absorption provided by this utility model is as follows: First, the glass tube is placed vertically in the glass tube placement ring 13 of the glass tube placement rack 12, so that the lower end of the glass tube is inserted into the interior of the rubber sleeve 23. The elastic material of the rubber sleeve 23 has a certain deformation capacity. When inserted, it can slightly wrap around the lower end of the glass tube to form a flexible fixation, which not only ensures that the glass tube does not shake during the conveying process, but also avoids damage caused by hard contact. The elastic body of the rubber sleeve 23 can absorb vertical vibration. When the conveyor belt 4 starts or stops or the glass tube placement rack 12 moves, the rubber sleeve 23 buffers the vertical impact of the glass tube through deformation, reducing the cracking or breakage of the glass tube caused by vibration.Subsequently, the servo motor 5 starts after receiving the electrical signal from the microcontroller 14. Its output shaft drives the left conveyor roller 3 to rotate, which in turn drives all the conveyor rollers 3 to operate synchronously via the conveyor belt 4. When the conveyor belt 4 is running, the glass tube placement rack 12 moves vertically, transporting the glass tube to the designated position. The slide rails 22 on the left and right sides of the glass tube placement rack 12 cooperate with the rubber strips 21 on the left and right sides of the bracket 1. When the glass tube placement rack 12 moves, the slide rails 22 contact the rubber strips 21, using the elasticity of the rubber strips 21 to absorb lateral vibrations and prevent the glass tube from being damaged by collision due to left and right swaying. The adjustment groove 25 on the adjustment plate 24 can slide the limit bracket 26 to drive the rubber sleeve 23 to extend and retract, thereby adjusting the height of the rubber sleeve 23. After adjustment, the glass tube can be transported to the designated position. The limiting bracket is fixed by tightening screw 27 to accommodate glass tubes of different heights. During this process, the conveyor belt 4 carries the glass tube placement bracket 12 in a cyclical manner. When the glass tube placement bracket 12 is not within the detection range, the infrared light emitted by the infrared sensor 9 propagates through the air to the reflector plate 11 on the right side. The reflector plate 11 is a stainless steel reflector plate, which reflects the infrared light back to the infrared sensor 9. The infrared sensor 9 continuously receives the infrared light, forming a stable detection circuit. When the glass tube placement bracket 12 moves with the conveyor belt 4 to the detection area between the lower infrared sensor 9 and the lower reflector plate 11, the solid structure of the glass tube placement bracket 12 blocks the transmission path of the infrared light, causing the infrared light to... Upon receiving a signal change from the infrared sensor 9 on the lower side, the microcontroller 14 immediately sends an electrical signal indicating an obstacle has been detected. After receiving the signal change from the infrared sensor 9, the microcontroller 14 executes the preset control logic: it sends a stop command to the servo motor 5, causing the servo motor 5 to stop operating, the conveyor belt 4 to lose power, and the glass tube holder 12 to stop moving. It then precisely positions itself within the detection range of the infrared sensor 9, i.e., the preset target position. At this point, the user can place the glass tube inside the glass tube holder 12. The user then manually operates the microcontroller 14 to make the servo motor 5 run, causing the conveyor roller 3 to rotate again, and the conveyor belt 4 to move the glass tube holder 12 again, until the glass tube holder 12 moves to the upper infrared sensor 9 and the upper... When the infrared light is detected in the detection area between the reflectors 11, the solid structure of the glass tube holder 12 blocks the transmission path of the infrared light, causing a change in the transmission path of the infrared light. Immediately afterward, an electrical signal indicating "obstacle detected" is sent to the microcontroller 14. Upon receiving the signal change from the upper infrared sensor 9, the microcontroller 14 executes the preset control logic: it sends a stop command to the servo motor 5, causing the servo motor 5 to stop operating, the conveyor belt 4 to lose power, and the glass tube holder 12 to stop moving. At this point, the user can remove the glass tube. The slide block 8 can slide within the groove 7 of the mounting plate 6 and is fixed in position by the tightening screw 10, thereby adjusting the height of the infrared sensor 9 to meet the requirements of the glass tube loading position.

[0025] It is worth noting that the servo motor 5 disclosed in the above embodiments can be selected from the SGM7J series, the infrared sensor 9 can be model E18-D80NK, and the microcontroller 14 can be model STC89C52. The microcontroller 14 controls the servo motor 5 and the infrared sensor 9 using methods commonly used in the prior art.
