Description

Technical Field

[0001] This utility model relates to the field of chip taping machine technology, specifically a taping feeding mechanism for an integrated circuit chip testing taping machine. Background Technology

[0002] A chip taping machine is a specialized device used to feed loose electronic components into carrier tape after passing through inspection, reversing, and testing stations. It can be divided into two main categories: semi-automatic and fully automatic. It can significantly improve production efficiency and reduce labor costs. Chip taping machines are mainly used for packaging electronic components such as resistors, diodes, color-coded inductors, transistors, fuses, aluminum electrolytic capacitors, transistors, and LEDs. In addition, taping machines are widely used in the semiconductor, chip, and metal sheet industries. The taping feeding mechanism for a chip taping machine is a specialized device that provides the taping tape to the machine for subsequent taping processing.

[0003] Existing taping machines directly transport the tapes. However, during the tape feeding process, dust in the air can easily fall onto the tapes that need to be transported. Tape dust may affect chip production efficiency and chip quality. During the operation of the chip taping machine, dust may enter the chip, affecting chip performance and even causing chip damage.

[0004] For example, patent application number 202420202576.5 discloses a tape feeding mechanism for a chip tape feeding machine. This utility model can guide and limit the tape through a limiting ring, and can perform initial cleaning of dust adsorbed on the tape surface through a wiping pad. When the blowing component is running, the blowing component accelerates the air flow and can perform secondary cleaning of the dust on the surface of the feeding tape. However, the dust is removed by wiping and blowing in this paper. The dust is not effectively collected and isolated. It may cause the dust wiped off to float again under the blowing, and re-adhere to the cleaned part of the tape front, resulting in secondary dust contamination of the tape and making it difficult to effectively and thoroughly remove the dust.

[0005] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a tape feeding mechanism for an integrated circuit chip testing tape and reel machine. Utility Model Content

[0006] The purpose of this invention is to provide a tape feeding mechanism for an integrated circuit chip testing tape feeding machine, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a tape feeding mechanism for an integrated circuit chip testing tape feeding machine, comprising a conveying channel, with upright plates fixedly connected to the front and rear sides of the inner surface of the conveying channel, and limit roller groups rotatably connected to the left and right ends of the opposite side of the upright plate, with support rollers evenly distributed and rotatably connected to the lower part of the opposite side of the upright plate, and a wiping roller rotatably connected to the upper part of the middle of the opposite side of the upright plate, with a drive motor connected to the front end of the wiping roller penetrating the upright plate, and a filter box fixedly connected to the upper surface of the conveying channel, with a pipe fixedly connected to the upper surface of the filter box, and an air pump fixedly connected to the lower rear end of the pipe.

[0008] Preferably, the drive motor is fixedly connected to the front surface of the front upright plate, and the air pump is fixedly connected to the rear side of the outer surface of the conveying channel.

[0009] Preferably, the lower end of the inner surface of the filter box is rotatably connected to the front and rear sides of the shaft, and the surface of the shaft is fixedly connected to the movable plate, and the longitudinal length of the movable plate is half of the bottom opening of the filter box.

[0010] Preferably, torsion springs are fixedly connected to both the left and right sides of the surface of the movable plate, and the torsion springs are sleeved on the outside of the shaft, and the end of the torsion spring away from the movable plate is fixedly connected to the inner surface of the filter box.

[0011] Preferably, a connecting frame is fixedly connected to the lower side of the outer surface of the conveying channel, and the connecting frame is connected to the tape feeding machine using fasteners.

[0012] Preferably, a support rod is fixedly connected to the right end of the connecting frame, and a loading rack is installed on the front side of the upper surface of the support rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the arrangement of a wiping roller, a drive motor, a filter box, a pipeline, and an air pump, allows the wiping roller to rotate during the conveying of the tape. The rotation direction of the wiping roller is opposite to the movement direction of the tape. At this time, the wiping roller can effectively remove dust from the surface of the tape. Meanwhile, the air pump can draw gas from inside the conveying channel using the pipeline and filter box. That is, the dust wiped off by the wiping roller will enter the filter box with the airflow. After being captured and adsorbed by the filter element inside the filter box, the dust is collected, ensuring that the conveyed tape remains clean and preventing dust from adhering and affecting subsequent processing operations. It also prevents the dust from being re-flying and causing re-contamination of the cleaned tape, thus ensuring the cleanliness of the tape after cleaning.

[0015] 2. This utility model, through the arrangement of a shaft, a movable plate, and a torsion spring, creates a negative pressure inside the filter box when the air pump is drawing air. This pressure, combined with the external air pressure, pushes the movable plate upwards via the shaft to open the filter box, ensuring normal air intake for the air pump and normal air intake for filtration. When the equipment stops, the filter box ceases exhaust. At this time, the torsion spring pulls the movable plate downwards via the shaft, sealing the bottom opening of the filter box. This effectively prevents dust captured by the filter element inside the filter box from falling and escaping after the equipment stops working, avoiding dust directly falling and contaminating the entire conveying channel, and ensuring that dust is stably collected inside the filter box.

[0020] 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.

[0021] like Figures 1-3As shown, a tape feeding mechanism for an integrated circuit chip testing tape feeding machine includes a conveying channel 1. Vertical plates 2 are fixedly connected to the front and rear sides of the inner surface of the conveying channel 1. Limiting roller groups 3 are rotatably connected to the left and right ends of the facing side of the vertical plate 2. Support rollers 4 are evenly distributed and rotatably connected to the lower part of the facing side of the vertical plate 2. A wiping roller 5 is rotatably connected to the upper part of the middle of the facing side of the vertical plate 2. A drive motor 6 is connected to the front end of the wiping roller 5 through the vertical plate 2. A filter box 7 is fixedly connected to the upper surface of the conveying channel 1. A pipe 8 is fixedly connected to the upper surface of the filter box 7. An air pump 9 is fixedly connected to the lower rear end of the pipe 8. The drive motor 6 is fixedly connected to the front surface of the front vertical plate 2, and the air pump 9 is fixedly connected to the rear side of the outer surface of the conveying channel 1.

[0022] By adopting the above technical solution, when the tape is being conveyed, the drive motor 6 drives the wiping roller 5 to rotate. The rotation direction of the wiping roller 5 is opposite to the direction of tape movement. At this time, the wiping roller 5 can effectively wipe away the dust on the surface of the tape.

[0023] The support roller 4 supports the bottom of the tape to prevent the tape from sinking and dragging on the ground. The support roller 4 itself can rotate, which can reduce the friction between it and the tape when supporting the tape.

[0024] The limiting roller group 3 can position the tape input and output positions to prevent tape deviation;

[0025] The air pump 9 uses the pipe 8 and the filter box 7 to draw in the gas inside the delivery channel 1. The dust wiped off by the wiping roller 5 will enter the filter box 7 with the airflow and be captured and adsorbed by the filter element inside the filter box 7, so that the dust is collected.

[0026] Furthermore, the lower end of the inner surface of the filter box 7 is rotatably connected to the front and rear sides of the shaft 10, and the surface of the shaft 10 is fixedly connected to the movable plate 11, and the longitudinal length of the movable plate 11 is half of the bottom opening of the filter box 7.

[0027] By adopting the above technical solution, when the air pump 9 draws air, a negative pressure is formed inside the filter box 7, which pushes the movable plate 11 from bottom to top under the external air pressure and rotates upward using the shaft 10 to open it, thereby ensuring the normal air intake of the air pump 9 and the normal air reception and filtration of the filter box 7.

[0028] Furthermore, torsion springs 12 are fixedly connected to both the left and right sides of the surface of the movable plate 11, and the torsion springs 12 are sleeved on the outside of the shaft 10, and the end of the torsion spring 12 away from the movable plate 11 is fixedly connected to the inner surface of the filter box 7.

[0029] By adopting the above technical solution, when the equipment is stopped, the filter box 7 no longer exhausts air. At this time, under the action of the torsion spring 12, the movable plate 11 will be pulled to rotate downward through the shaft 10, thereby sealing the bottom opening of the filter box 7.

[0030] Furthermore, a connecting frame 13 is fixedly connected to the lower side of the outer surface of the conveying channel 1, and the connecting frame 13 is connected to the tape feeding machine using fasteners;

[0031] The right end of the connecting frame 13 is fixedly connected to the support rod 14, and the front side of the upper surface of the support rod 14 is equipped with a loading rack 15.

[0032] By adopting the above technical solution, the entire feeding mechanism is installed at the position where the tape machine needs to be fed using the connecting frame 13; the loading frame 15 can be used to install the tape rolls that need to be conveyed.

[0033] Working Principle: When using this integrated circuit chip to test the tape feeding mechanism of the tape feeding machine, firstly, the tape is positioned by the limit roller group 3 and enters from the right end and exits from the left end of the conveying channel 1. The tape is located inside the conveying channel 1 and is supported by the support roller 4. At this time, the wiping roller 5 is in contact with the upper surface of the tape. During the conveying process, the drive motor 6 drives the wiping roller 5 to rotate. The rotation direction of the wiping roller 5 is opposite to the movement direction of the tape. At this time, the wiping roller 5 can effectively wipe away the dust on the surface of the tape. At the same time, the air pump 9 can draw gas from the inside of the conveying channel 1 through the pipe 8 and the filter box 7. When the air pump 9 draws gas, a negative pressure is formed inside the filter box 7, thereby pushing the movable plate 11 from bottom to top under the external air pressure. The shaft 10 rotates upward to open, ensuring normal air intake for the air pump 9. Dust wiped off by the wiping roller 5 enters the filter box 7 with the airflow. The dust is captured and adsorbed by the filter element inside the filter box 7, ensuring that the conveyed tape remains clean and preventing dust adhesion from affecting subsequent processing operations. When the equipment stops, the filter box 7 stops exhausting air. At this time, under the action of the torsion spring 12, the movable plate 11 is pulled to rotate downward through the shaft 10, thereby closing the bottom opening of the filter box 7. This effectively prevents the dust captured by the filter element inside the filter box 7 from falling and escaping after the equipment stops working. This is the working principle of the tape feeding mechanism of the integrated circuit chip testing tape machine.
