Description

Technical Field

[0001] This utility model relates to the field of winding mechanism technology, specifically to an electronic carrier tape winding mechanism. Background Technology

[0002] Electronic carrier tape winding mechanisms are core automated auxiliary equipment in the packaging, storage, and surface mount processes of electronic components. They are mainly used to orderly wind and precisely unwind electronic carrier tapes loaded with micro-electronic components (such as chips, resistors, capacitors, connectors, etc.), while ensuring the integrity, positioning accuracy, and pick-and-place stability of components during transmission, storage, and subsequent surface mount processes. They are a key connecting device in the electronic component supply chain from packaging to final assembly.

[0003] The core function of the electronic carrier tape winding mechanism is to wind the packaged carrier tape (usually with a sealing tape) containing the components into a roll, which facilitates warehousing and long-distance transportation and prevents the carrier tape from bending, components from falling off or being damaged.

[0004] Electronic carrier tape winding mechanisms need to detect tape breaks and material shortages. Currently, tape break and material shortage detection relies heavily on photoelectric sensors. Existing electronic carrier tape winding mechanisms cannot clean the top sealing tape. Once the carrier tape surface is contaminated, it will cause uneven reflection of the top sealing tape, which can easily trigger false alarms of tape breakage, leading to frequent equipment shutdowns, reduced production efficiency, and even irregular winding reels. It can also change the friction coefficient of the carrier tape surface, causing uneven tension in different areas during winding. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0026] like Figures 1 to 5 As shown, this embodiment provides an electronic carrier tape winding mechanism, including a winding mounting frame 1, a contact cleaning mechanism 2, a circulation enhancement mechanism 3, and a pneumatic enhancement mechanism 4. The contact cleaning mechanism 2 is mounted on the winding mounting frame 1 and includes a contact cleaning component 21, a contact power component 22, and a dehumidification component 23. The contact cleaning component 21 is mounted on the winding mounting frame 1, the contact power component 22 is mounted on the contact cleaning component 21, and the dehumidification component 23 is disposed within the contact cleaning component 21. The circulation enhancement mechanism 3 is disposed on one side of the contact cleaning component 21. The pneumatic enhancement mechanism 4 is disposed on the contact cleaning component 21.

[0027] like Figures 1 to 4As shown, the contact cleaning assembly 21 includes: a contact cleaning positioning chamber 211, a pair of contact cleaning flexible cloths 212, a pair of contact cleaning support rollers 213, and a pair of contact cleaning positioning elements 214. The contact cleaning positioning chamber 211 is mounted on the winding mounting frame 1. The contact cleaning positioning chamber 211 can contain the cleaning fluid and protect the various structures within it, thus extending the service life of the internal structures. The pair of contact cleaning flexible cloths 212 are located within the contact cleaning positioning chamber 211. The contact cleaning flexible cloths 212 clean the upper cover of the carrier belt, reducing dust accumulation and making the reflectivity of the upper cover more uniform. The pair of contact cleaning support rollers 213 are located within the contact cleaning flexible cloths 212. The pair of contact cleaning support rollers 213 support the contact cleaning flexible cloths 212 and position them, reducing the likelihood of the contact cleaning flexible cloths 212 detaching or shifting. A pair of contact cleaning positioning elements 214 are disposed at both ends of the contact cleaning support roller 213. The positioning elements 214 can position the contact cleaning support roller 213, improve the stability of the contact cleaning support roller 213, reduce the probability of the contact cleaning support roller 213 detaching, improve the balance of the contact cleaning support roller 213, and make the contact cleaning flexible cloth 212 better fit with the top cover. The winding mounting frame 1 is chiseled with positioning grooves that match the contact cleaning positioning chamber 211, which facilitates the installation of the contact cleaning positioning chamber 211 and improves the cleaning effect of the contact cleaning flexible cloth 212 on the roll. The contact cleaning flexible cloth 212 matches the contact cleaning support roller 213, and the contact cleaning support roller 213 matches the pair of contact cleaning positioning elements 214. The contact cleaning positioning elements 214 are fixedly installed with the contact cleaning positioning chamber 211.

[0028] like Figures 1 to 4As shown, the contact power assembly 22 includes: a contact motor 221, a contact drive pulley 222, a pair of contact driven pulleys 223, and a contact timing belt 224. The contact motor 221 is mounted on the contact cleaning positioning chamber 211. The contact motor 221 drives the contact drive pulley 222, providing the necessary power and improving its controllability. The contact drive pulley 222 is located at the end of the contact motor 221 near the contact cleaning positioning chamber 211. The contact drive pulley 222 drives the contact timing belt 224, enabling the contact timing belt 224 to transmit power and drive the rotation of the pair of contact driven pulleys 223. A pair of driven contact pulleys 223 are positioned on either side of the driving contact pulley 222. These driven pulleys 223 are driven by the contact timing belt 224 to rotate, which in turn drives the contact cleaning support roller 213, causing the contact cleaning flexible cloth 212 to rotate and clean the carrier belt. The contact timing belt 224 is positioned between the driving contact pulley 222 and the pair of driven contact pulleys 223, serving a transmission function. A contact motor 221 passes through the contact cleaning positioning chamber 211. The driven contact pulleys 223 and the contact cleaning support roller 213 are fixedly installed, and both the driven contact pulleys 223 and the driving contact pulley 222 are matched with the contact timing belt 224.

[0029] like Figures 1 to 3As shown, the squeeze dehumidification assembly 23 includes: a squeeze dehumidification chamber 231, a squeeze dehumidification shaft 232, a pair of squeeze dehumidification rods 233, and a squeeze dehumidification spring 234. The squeeze dehumidification chamber 231 is positioned on one side of the pair of contact cleaning flexible cloths 212. The chamber 231 positions the squeeze dehumidification shaft 232, improving its stability. Simultaneously, its own displacement drives the displacement of the squeeze dehumidification shaft 232, allowing it to better squeeze the contact cleaning flexible cloths 212, squeezing out the cleaning fluid. The squeeze dehumidification shaft 232 is rotatably mounted within the squeeze dehumidification chamber 231. This shaft squeezes the contact cleaning flexible cloths 212, squeezing out the cleaning fluid and reducing the possibility of excessive liquid within the cloths, thus allowing the moistened cloths to better clean the carrier belt. A pair of dehumidifying compression rods 233 are positioned on the side of the dehumidifying compression chamber 231 away from the contact cleaning flexible cloth 212. The rods 233 position the chamber and can be slidably moved. A dehumidifying compression spring 234 is fitted onto the rods 233, allowing for pulling and tugging, thus improving the engagement of the dehumidifying compression shaft 232 with the contact cleaning support roller 213 to compress the contact cleaning flexible cloth 212. The dehumidifying compression rods 233 penetrate the contact cleaning positioning chamber 211, and the spring 234 is positioned between the rods 233 and the chamber.

[0030] like Figures 1 to 5 As shown, the circulation enhancement mechanism 3 includes: a circulating water pump 31, a circulating flushing chamber 32, and a circulating filter 33. The circulating water pump 31 is located on one side of the contact cleaning positioning chamber 211. The circulating water pump 31 can extract liquid from the contact cleaning positioning chamber 211 and inject the cleaning fluid into the circulating flushing chamber 32. The circulating flushing chamber 32 is located inside the contact cleaning positioning chamber 211 and on one side of a pair of contact cleaning flexible cloths 212. The circulating filter 33 is located inside the contact cleaning positioning chamber 211 and below the pair of contact cleaning flexible cloths 212. The circulating filter 33 can filter the cleaning fluid, allowing it to be recycled. The circulating water pump 31 passes through both the contact cleaning positioning chamber 211 and the circulating flushing chamber 32.

[0031] like Figures 1 to 5As shown, the wind-driven efficiency enhancement mechanism 4 includes: a wind-driven mounting chamber 41, a wind-driven motor 42, a wind-driven fan 43, a wind-driven injection chamber 44, and a wind-driven barrier screen 45. The wind-driven mounting chamber 41 is mounted on the contact cleaning positioning chamber 211. The mounting chamber 41 facilitates airflow and provides a suitable location for the installation of the wind-driven motor 42. Furthermore, the wind-driven motor 42 prevents the entry of external dust and facilitates the rotation of the wind-driven fan 43. The wind-driven motor 42 is located on the side of the wind-driven mounting chamber 41 away from the contact cleaning positioning chamber 211 and extends through the chamber. The wind-driven motor 42 drives the rotation of the wind-driven fan 43, providing the necessary power for its rotation. The wind-driven fan 43 is mounted on the wind-driven motor 42 and draws in outside air, injecting it into the wind-driven injection chamber 44. A pneumatic injection chamber 44 is disposed within and extends through the contact cleaning positioning chamber 211, and is positioned on the side of the pair of contact cleaning flexible cloths 212 furthest from the circulating water pump 31. The pneumatic injection chamber 44 can temporarily contain air and simultaneously allow air to dry the contact cleaning flexible cloths 212, reducing the likelihood of cleaning liquid evaporating from the contact cleaning positioning chamber 211 wetting the contact cleaning flexible cloths 212. A pneumatic barrier net 45 is disposed on the side of the pneumatic injection chamber 44 near the contact cleaning flexible cloths 212.
