Description

Technical Field

[0001] This invention relates to the field of tape and reel machine technology, specifically to a tape and reel flattening device and a tape and reel machine. Background Technology

[0002] In the fields of electronic component manufacturing, chip packaging, and surface mount technology (SMT), tape and reel are the core packaging form for electronic components. The stability of their movement directly affects the imaging quality and detection accuracy of the vision inspection system. In the existing Reelto Reel appearance inspection system, the depth of field of its vision system is only 13μm. Therefore, in order to ensure real-time appearance inspection, the tape and reel need to be stable during movement, and the vertical jump should not exceed 13μm. Otherwise, it will lead to problems such as blurred imaging and failure to recognize feature points.

[0003] Existing technologies employ a mechanical limiting scheme where an upper pressure roller presses down on the tape to achieve stable tape transmission. This applies vertical pressure to the tape via the upper pressure roller, ensuring it adheres tightly to the lower platform and thus restraining and suppressing longitudinal vibration. However, this scheme has the following drawbacks:

[0004] 1. There are significant differences in the thickness specifications of the tape. When switching to tapes of different thicknesses, the platform of the corresponding thickness must be disassembled and replaced. This not only requires machine downtime but also requires recalibrating the platform level after replacement, which seriously affects the production speed.

[0005] 2. There are significant differences in the tape width specifications. When changing the tape width, it is necessary to frequently change the position of the upper pressure roller. The width adjustment takes a long time and seriously affects the production speed.

[0006] 3. When the tape retracts, excessive friction may cause the tape to break and damage the product;

[0007] Patent document CN110255251A discloses a tape feeding device for a pick-and-place machine. It uses pressure rollers at the bottom of the mounting base to press the tape tightly against the base, ensuring the tape is close to the base when picking up the pick-and-place device, facilitating flatness during transport. However, this solution suffers from the aforementioned problems of not being applicable to different tape specifications and not being able to adjust the friction. Summary of the Invention

[0060] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0061] This invention discloses a tape flattening device and a tape machine. By setting an electric lifting platform mechanism at the bottom of the tape, it can achieve adaptive adjustment of tapes of different thicknesses. Moreover, the motor control can significantly save time and costs, solving the technical problem of frequent platform replacement required in existing solutions to cope with tapes of different thicknesses. Furthermore, a floating pressure plate mechanism is adopted above the tape. The pressure applied to the pressure plate can be adjusted by the pressure adjustment components on both sides, ensuring that the tape is flattened without damaging it.

By setting an electric lifting platform mechanism at the bottom of the tape, adaptive adjustment for tapes of different thicknesses can be achieved. Furthermore, motor control can significantly save time costs and provides relatively higher precision, solving the technical problem of frequent platform replacement required in existing solutions to handle tapes of different thicknesses.

[0064] In a preferred embodiment, the electric lifting platform mechanism 100 further includes an adjusting plate 1005, adjusting screws 1006, and a second connecting plate 1007.

[0066] In a preferred embodiment, the floating pressure plate mechanism 200 further includes a lifting cylinder 2004 and a fourth connecting plate 2005. The fourth connecting plate 2005 is connected to the electric lifting platform mechanism 100 and is relatively fixed to the fixed part of the electric lifting slide 1004. The third connecting plate 2003 is mounted on top of the fourth connecting plate 2005 via the lifting cylinder 2004 and can slide along the linear guide rail 2007 under the drive of the lifting cylinder 2004. By setting a lifting cylinder at the bottom of the pressure plate, when the tape needs to be retracted, the pressure plate is lifted by the cylinder, while the electric lifting platform descends, ensuring that the tape receives minimal friction and does not damage the product.

[0067] In a preferred embodiment, the first pressure adjustment assembly includes a first adjustment block 2008, a first support column 2009, and a second support column 2011.

A first tensioning mechanism is installed between the first support column 2009 and the second support column 2011. When the pressure plate 2001 contacts the tape, the first tensioning mechanism is in a tensioned state, used to apply an upward pulling force to the third connecting plate 2003 through the second support column 2011. The first tensioning mechanism includes a tension spring 2010.

[0068] The second pressure adjustment assembly includes a second adjustment block 2014, a third support column 2012, and a fourth support column 2013. The third support column 2012 is fixedly installed on the other side of the third connecting plate 2003 and is located at a third height. The second adjustment block 2014 is installed on the other side of the fifth connecting plate 2006, and its vertical position is adjustable. The fourth support column 2013 is installed on the second adjustment block 2014 and is located at a fourth height. The third height is higher than the fourth height. A second tensioning mechanism is installed between the third support column 2012 and the fourth support column 2013. When the pressure plate 2001 contacts the tape, the second tensioning mechanism is in a tensioned state, used to apply a downward pulling force to the third connecting plate 2003 through the third support column 2012. The second tensioning mechanism includes a tension spring 2010. The downward force of the pressure plate 2001 can be reduced by adjusting the first adjustment block 2008 on one side upwards. The second adjustment block 2014 on the other side can be adjusted downward to increase the downward force of the pressure plate 2001. The combination of the two can achieve the effect of the floating pressure plate 2001, which can ensure that the tape is flattened without damaging the tape.
