Description

Technical Field

[0001] This utility model relates to the field of semiconductor manufacturing technology, and in particular to a semiconductor tape feeding device. Background Technology

[0002] Semiconductor chips need to be stored and transported via tape, which is then layered and wound onto a reel. The tape consists of a carrier tape that holds the chip and a protective film covering the carrier tape. In the relevant processes of semiconductor manufacturing, the tape needs to be unwound and the carrier tape and protective film need to be separated.

[0003] However, during the unwinding process, due to the discontinuity of the process, continuous unwinding of the material strip can lead to accumulation, making it difficult to pull the material normally afterwards. In addition, as the unwinding time progresses, the diameter of the material tray decreases, and the conveyor speed of the material strip decreases, which can cause problems such as material strip pulling. If the conveyor speed of the material strip cannot be adjusted in time, it will affect the normal conveying of the material strip, thereby affecting related processes. Utility Model Content

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.

[0026] Example 1

[0027] like Figure 1-3As shown, a semiconductor tape unloading device includes a frame 1, an unwinding reel 2, a rewinding reel 3, and a drive assembly 4. The unwinding reel 2 is located at the upper end of the frame 1 and is used to unwind the tape. The rewinding reel 3 is located directly below the unwinding reel 2 and is used to rewind the protective film. The rewinding reel 3 is located below the unwinding reel 2, which can shorten and simplify the winding path of the protective film and facilitate the winding and recycling of the protective film. The unwinding reel 2 and the rewinding reel 3 are rotatably connected to the frame 1 through a drive assembly 4. Multiple guide rollers 5 are provided between the unwinding reel 2 and the rewinding reel 3 for guiding the protective film and the direction of the carrier tape conveying. A sensor assembly 6 is also provided on one side of the frame 1 between the unwinding reel 2 and the rewinding reel 3. The sensor assembly 6 includes multiple detection sensors for detecting the position of the carrier tape conveying. The drive assembly 5 is electrically connected to the sensor assembly 6 and controls the rotation speed of the unwinding reel 2 and the rewinding reel 3 through the detection position of the sensor assembly.

[0028] like Figure 1 As shown, the sensor assembly 6 includes an upper detection sensor 61, a middle detection sensor 62, and a lower detection sensor 63 arranged sequentially in the vertical direction. The detection position of the middle detection sensor 62 is close to the guide roller 5 at the end of the carrier belt conveying direction. Specifically, the detection height of the middle detection sensor 62 is similar to the height of the guide roller 5 at the end of the carrier belt conveying direction, that is, similar to the height of the guide roller 51c. The spacing between the upper detection sensor 61 and the middle detection sensor 62, and between the middle detection sensor 62 and the lower detection sensor 63, is set according to the unwinding tension of the carrier belt, generally 50-90mm. Through the three detection sensors, the height of the end of the carrier belt conveying is detected, thereby detecting the slack of the carrier belt. The drive assembly 4 adjusts the rotation speed of the unwinding and rewinding reels according to the slack of the carrier belt, adjusts the unwinding conveying speed of the carrier belt in real time, and makes the conveying tension of the carrier belt uniform, so that the unwinding speed of the carrier belt is adapted to the actual feeding needs of the carrier belt, avoiding accumulation or pulling, and ensuring the stability of the unwinding of the carrier belt.

[0029] Sensor assembly 6 also includes a lower limit sensor 64 located below the lower detection sensor 63. When the lower limit sensor 64 is triggered, it indicates that there is a carrier tape accumulation, requiring the drive assembly 4 to be stopped and a warning to be issued to remind the user to check the situation.

[0030] like Figure 1 , 3 As shown, multiple guide rollers 5 include guide roller one 51a, guide roller two 51b, and guide roller three 51c. Guide roller one 51a and guide roller two 51b are located on the side of the unwinding reel 2 away from the sensor assembly 6, and are used to guide the protective film of the unwinding reel 2 to the take-up reel 3. Guide roller one 51a and guide roller two 51b are arranged vertically from top to bottom. Guide roller three 51c is located diagonally below the unwinding reel 2 and is used to guide the carrier belt of the unwinding reel 3 to the rear end of the conveyor.

[0031] The guide roller 5 includes a connecting rod 52 and two guide wheels 53 mounted on the connecting rod 52. The connecting rod 52 is fixed to the frame 1 by a connecting plate 54. The two guide wheels 53 are arranged opposite to each other and are rotatably connected to the connecting rod 52 by bearings, and the two guide wheels 53 form a guide groove. The guide wheels are designed to roll, which can reduce conveying friction and reduce damage to the carrier belt and protective film during conveying. Furthermore, the guide groove guides the conveying direction of the carrier belt and protective film, preventing deviation and affecting the subsequent processes and the winding and recycling quality of the protective film.

[0032] like Figure 1 , 2 As shown, the drive assembly 4 includes a mounting plate 41 and a servo motor 42, a reducer 43, a connecting seat 44, and a hand-operated expansion shaft 45 mounted on the mounting plate 41. The mounting plate 41 is mounted on the frame 1. The servo motor 42 is connected to the reducer 43. One end of the connecting seat 44 is equipped with the reducer 43, and the other end is equipped with a bearing seat 46. The hand-operated expansion shaft 45 is rotatably connected to the connecting seat 44 through the bearing seat 46, and one end of the hand-operated expansion shaft passes through the bearing seat 46 and extends into the connecting seat 44, and is connected to the output end of the reducer 43 through a coupling. A knob is provided at the front end of the hand-operated expansion shaft 45. Rotating the knob can tighten the material tray onto the hand-operated expansion shaft 45.

[0033] like Figure 1 As shown, the semiconductor tape feeding device also includes multiple particle nozzles 7, which are fixed on the frame 1 and set along the conveying path of the carrier tape or protective film to remove static electricity from the carrier tape or protective film and prevent dust from sticking.

[0034] like Figure 1 As shown, the semiconductor strip feeding device described above also includes a sensing sensor 8 located above the feeding side of the unwinding reel 2. The sensing sensor 8 is used to detect the amount of material on the unwinding reel 2, monitor whether there is any strip on the unwinding reel, control the replacement of the unwinding reel, and determine whether feeding is required.

[0035] like Figure 1 As shown, a material breakage detection sensor 9 is also provided on one side of the frame 1. The material breakage detection sensor 9 and the sensor assembly 6 work together to form a dual monitoring system, enabling more comprehensive monitoring.

[0036] like Figure 1 As shown, the frame 1 is assembled from aluminum alloy beams and is covered with a protective plate. The bottom of the frame is equipped with adjustable feet and casters, making it lightweight, aesthetically pleasing, and easy to install and maintain. In addition, a touchscreen is located on the outside of the frame 1, and a three-color warning light is located on the top.

[0037] This utility model features a lightweight structure, attractive appearance, and ease of installation and daily maintenance. It monitors the slack of the carrier belt using sensor components, and the drive components adjust the rotation speed of the unwinding and rewinding reels based on the slack, thereby adjusting the unwinding speed of the carrier belt in real time. This ensures that the unwinding speed of the carrier belt matches the actual material supply requirements, preventing accumulation or pulling, guaranteeing the stability of the carrier belt unwinding, and improving overall work efficiency.
