Description

Technical Field

[0001] This utility model relates to the field of carrier belt cleaning technology, specifically to a carrier belt cavity cleaning and dust removal device. Background Technology

[0002] Carrier tape is a key auxiliary consumable in the packaging, transportation, and automated production of electronic components. It is typically made of plastic or paper as the base material and is a strip structure. The tape has cavities spaced at fixed intervals along its length to accommodate electronic components, and also features positioning holes for precise positioning. The entire tape can be rolled into a disc for easy storage. In use, the carrier tape is paired with a cover tape to place miniature electronic components such as resistors, capacitors, transistors, and diodes within the cavities.

[0003] During long-term cyclic use, carrier tapes easily accumulate dust, microparticles, and manufacturing debris inside the cavities used to hold electronic components. Due to the depth of the cavities and the narrow inner walls, current brush cleaning methods have significant limitations—brush bristles cannot reach the bottom and corners of the cavities, only cleaning surface dust and failing to thoroughly remove stubborn impurities adhering to the inner walls. These residual impurities can have multiple adverse effects on the subsequent use of the carrier tape: firstly, they may contaminate the electronic components to be packaged, affecting product performance and quality; secondly, they may interfere with the precise positioning and gripping of components by automated equipment. Utility Model Content

[0004] To solve the above-mentioned problems, this utility model proposes a carrier tape cavity cleaning and dust removal device that facilitates the removal of stubborn impurities in the cavity and ensures the stability and safety of subsequent transportation of electronic components.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: a cleaning and dust removal device for the cavity of a carrier tape, comprising:

[0006] The frame includes a top plate and several legs, the legs being fixedly installed below the top plate, and guide ramps and frame plates being fixedly installed at both ends of the frame;

[0007] The guide frame is a U-shaped frame, symmetrically fixed on both sides of the bottom surface of the top plate, with several ball bearings on the upper and lower inner walls.

[0008] The high-pressure jet frame is fixedly installed below the guide frame and spans two guide frames. It has several jet holes evenly spaced on it and an air supply interface integrally formed below.

[0009] The collection bucket is fixed between each support leg and located directly below the top plate, with an air extraction pipe on the bottom surface;

[0010] The push rod is located at the end of the frame away from the guide plate. It is driven by a multi-stage electric push rod to move along the length of the guide frame and is lifted and lowered by a cylinder fixed on the frame plate.

[0011] Furthermore, the outriggers are located at the four corners below the top plate, and their lower ends extend outwards to provide reinforced support feet.

[0012] Furthermore, the balls on the upper and lower walls of the guide frame correspond one-to-one.

[0013] Furthermore, several high-pressure jet frames are arranged parallel to each other along the length of the guide frame and are arranged obliquely upwards.

[0014] Furthermore, the frame plate is provided with a lifting support plate, the cylinder drive end is connected to the bottom surface of the lifting support plate, and the multi-stage electric push rod is fixedly mounted on the support plate.

[0015] Furthermore, the push rod is equipped with a protective pad.

[0016] Compared with existing technologies, this invention has the following advantages: The high-pressure jet frame adopts a multi-set parallel and upwardly angled layout, coupled with equidistant jet holes, which can form a multi-angle, wide-coverage high-pressure airflow. This airflow can penetrate deep into the crevices and gaps, generating a strong impact on stubborn impurities, effectively breaking down their adhesion and solving the problem of incomplete cleaning by airflow in a single direction. The guide frame, through a symmetrical ball bearing structure, achieves smooth transport of the carrier belt, reducing positional deviation caused by friction. Combined with the multi-stage electric adjustment of the push rod and the protective pad design, it can precisely drive the carrier belt to move in multiple positions, ensuring that each cavity receives airflow cleaning while preventing scratches on the carrier belt and ensuring its integrity. At the same time, the collection hopper promptly collects the blown-off impurities, preventing secondary pollution and providing a clean environment for subsequent electronic component transportation. This avoids the risk of component jamming and damage caused by impurities from the source, ensuring stable and safe transportation. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] Combined with appendix Figure 1 Appendix Figure 3 Appendix Figure 4 A dust removal device for cleaning the cavity of a carrier belt includes: a frame, including a top plate 1 and several legs 2, the legs 2 being fixedly installed below the top plate 1, guide inclined plates 3 and frame plates 4 being fixedly installed at both ends of the frame, the legs 2 being installed at the four corners below the top plate 1, and the lower ends of the legs extending outwards from the frame to provide reinforced feet, which can make the frame more evenly stressed, greatly improve the overall support stability of the device, and prevent position displacement caused by vibration during the cleaning process.

[0024] Combined with appendix Figure 4 The guide frame 5 is a U-shaped frame, symmetrically fixed on both sides of the bottom surface of the top plate 1. Several balls 6 are provided on the upper and lower inner walls. The balls 6 on the upper and lower inner walls of the guide frame 5 correspond one-to-one, which can form symmetrical upper and lower guiding support for the carrier belt, reduce the frictional resistance when the carrier belt moves, and ensure that the carrier belt is always transported smoothly along the preset trajectory.

[0025] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 4 The high-pressure jet frame 7 is fixedly installed below the guide frame 5 and spans across the two guide frames 5. It has several jet holes 8 evenly spaced on it and an air supply interface 9 integrally formed below. The high-pressure jet frame 7 is arranged parallel to the length of the guide frame 5 and is obliquely upward, which can expand the coverage of the high-pressure airflow on the carrier tape holes, so that dust in different positions in the holes can be effectively blown away, improving the thoroughness of cleaning.

[0026] Combined with appendix Figure 2 Appendix Figure 4 The collection bucket 10 is fixed between each support leg 2 and located directly below the top plate 1. The bottom surface is equipped with an exhaust pipe 15, which can clean up the falling dust in time and avoid secondary pollution.

[0027] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 4The push rod 11 is located at the end of the frame away from the guide ramp 3. It is driven by a multi-stage electric telescopic rod 12 to move along the length of the guide frame 5, and is raised and lowered by a cylinder 13 fixed on the frame plate 4. The frame plate 4 is equipped with a lifting support plate 14. The driving end of the cylinder 13 is connected to the bottom surface of the lifting support plate 14. The multi-stage electric telescopic rod 12 is fixed on the lifting support plate 14. The cylinder can flexibly adjust the height of the push rod 11 to avoid obstructing the carrier belt from entering the guide frame 5. The multi-stage electric telescopic rod 12 can drive the push rod 11 to move, thereby moving the carrier belt within the guide frame 5, facilitating cleaning and removal from multiple locations. The push rod 11 is equipped with a protective pad to prevent direct hard contact between the push rod 11 and the carrier belt when pushing the carrier belt, preventing scratches on the carrier belt surface, and increasing friction for more stable pushing.

[0028] The specific implementation of this utility model is as follows: The carrier belt to be cleaned is placed into the guide frame 5 from the end away from the guide inclined plate 3. The carrier belt moves along the inner side of the guide frame 5. The ball bearings 6 on the upper and lower walls of the guide frame 5 reduce friction, ensuring that the carrier belt enters the cleaning area smoothly. The cylinder 13 on the control plate 4 drives the lifting support plate 14, and the height of the push rod 11 is adjusted to the appropriate position for the carrier belt. The high-pressure jet frame 7 is connected to the external high-pressure spray painting system through the air supply interface 9. The high-pressure jet system is started, and gas enters through the air supply interface 9 of the high-pressure jet frame 7 and is sprayed out as high-pressure airflow through the jet holes 8 to impact and clean stubborn impurities in the holes of the carrier belt. At the same time, the multi-stage electric telescopic rod 12 drives the push rod 11 to move along the length of the guide frame 5, pushing the carrier belt to move gradually so that each hole can be fully cleaned by the airflow. During the cleaning process, the blown-off impurities fall into the collection hopper 10 between the support legs 2 and are promptly removed through the exhaust pipe 15 to avoid secondary pollution. After the carrier belt has completely passed through the cleaning area, push rod 11 continues to push the carrier belt along guide ramp 3 to move it out, completing the entire cleaning process.
