Description

Technical Field

[0001] The present invention relates to the technical field of braiding machines, and in particular to a braiding flattening device and a braiding machine. Background Art

[0002] In the field of electronic component manufacturing, chip packaging and surface mount technology (SMT), the tape is the core packaging form of electronic component carriers. Its movement stability directly affects the imaging quality and detection accuracy of the visual inspection system. In the existing reel-to-reel appearance inspection system, the depth of field of its visual system is only 13μm. Therefore, in order to ensure real-time appearance inspection, the tape needs to be stable during movement, and the up and down jumps cannot exceed 13μm, otherwise it will cause problems such as blurred imaging and failure of feature point recognition.

[0003] In the prior art, a mechanical limit solution is used in which an upper pressure wheel presses the braid to achieve stable transmission of the braid. The upper pressure wheel applies vertical pressure to the braid to make it close to the lower platform, thereby restraining and suppressing longitudinal vibration. However, this solution has the following defects:

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

[0005] 2. There are significant differences in the specifications of the tape width. When switching the tape width, the position of the upper pressure wheel needs to be frequently changed. The width adjustment takes a long time, which seriously affects the production speed;

[0006] 3. When the braid moves backward, it will be broken due to excessive friction, thus damaging the product;

[0007] Patent document with publication number CN110255251A discloses a tape feeding device for a patch machine, which uses a pressing wheel at the bottom of the mounting seat to press the patch tape tightly, ensuring that the tape is close to the base when the patch is taken out, so that the tape is flat during transportation.

[0060] The present invention will be described in detail below with reference to specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several changes and improvements can still be made. These all belong to the protection scope of the present invention.

[0061] The present invention discloses a taping flattening device and a taping machine. By arranging an electric lifting platform mechanism at the bottom of the taping, the adaptive adjustment of taping with different thicknesses is realized, and the time cost can be greatly saved through motor control, solving the technical problem in the existing solution that the platform needs to be frequently replaced to cope with taping with different thicknesses. Further, a floating pressing plate mechanism is adopted above the taping, and the pressure applied to the pressing plate can be adjusted through the pressure adjustment components on both sides, while ensuring the flattening of the taping without damaging the taping.

[0062] According to the taping flattening device provided by the present invention, as Figure 1 shown, it includes an electric lifting platform mechanism 100 and a floating pressing plate mechanism 200;

[0063] As Figure 2As shown, the electric lifting platform mechanism 100 includes a platform 1001 and an electric lifting slide 1004. The platform 1001 is installed on the top of the electric lifting slide 1004 and can be lifted under the drive of the electric lifting slide 1004. The upper surface of the platform 1001 is used for placing the tape. The electric lifting platform mechanism 100 further includes a platform support block 1002 and a first connecting plate 1003.

By arranging the electric lifting platform mechanism at the bottom of the tape, the adaptive adjustment of tapes with different thicknesses is realized. Moreover, through motor control, the time cost can be greatly saved, and the accuracy is relatively higher, solving the technical problem that the platform needs to be frequently replaced in the existing solution to cope with tapes with different thicknesses.

[0064] In a preferred example, the electric lifting platform mechanism 100 further includes an adjustment plate 1005, adjustment screws 1006 and a second connecting plate 1007. The second connecting plate 1007 is fixedly installed on an external device. The electric lifting slide 1004 and the second connecting plate 1007 are both installed on the adjustment plate 1005, and the second connecting plate 1007 is located on both sides of the electric lifting slide 1004. The adjustment screws 1006 are arranged at the bottom of the adjustment plate 1005. The outer ring of the adjustment screw 1006 is connected to the adjustment plate 1005, and the inner ring of the adjustment screw 1006 is connected to the second connecting plate 1007.

The second pressure adjustment component is installed on the other side of the fifth connecting plate 2006 and the third connecting plate 2003 and is used to apply a downward adjustable pulling force on the third connecting plate 2003. The floating pressure plate mechanism 200 further includes a pressure plate support block 2002. The pressure plate support block 2002 is installed on the top of the third connecting plate 2003, and the pressure plate 2001 is installed on the top of the pressure plate support block 2002. By adopting a floating pressure plate mechanism above the tape, it can be applicable to flattening tapes of different widths, and the pressure applied to the pressure plate can be adjusted through the pressure adjustment components on both sides, while ensuring the flattening of the tape without damaging the tape.

[0066] In a preferred example, 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 remains relatively fixed to the fixed part of the electric lifting slide 1004. The third connecting plate 2003 is installed on the top of the fourth connecting plate 2005 through the lifting cylinder 2004 and can slide along the linear guide rail 2007 under the drive of the lifting cylinder 2004. By arranging 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, and at the same time the electric lifting platform descends, ensuring that the friction force received by the tape is minimized and the product is not damaged.

[0067] In a preferred example, the first pressure adjustment assembly includes a first adjustment block 2008, a first support column 2009, and a second support column 2011; the first adjustment block 2008 is installed on one side of the fifth connection plate 2006, and the vertical position of the first adjustment block 2008 can be adjusted.

A first tensioning mechanism is installed between the first support column 2009 and the second support column 2011. When the pressing plate 2001 contacts the tape, the first tensioning mechanism is in a tensioned state and is used to apply an upward pulling force to the third connection 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 connection plate 2003 and is located at a third height; the second adjustment block 2014 is installed on the other side of the fifth connection plate 2006, and the vertical position of the second adjustment block 2014 can be adjusted. A 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 pressing plate 2001 contacts the tape, the second tensioning mechanism is in a tensioned state and is used to apply a downward pulling force to the third connection plate 2003 through the third support column 2012. The second tensioning mechanism includes a tension spring 2010. By adjusting the first adjustment block 2008 on one side upward, the downward force of the pressing plate 2001 can be reduced. By adjusting the second adjustment block 2014 on the other side downward, the downward force of the pressing plate 2001 can be increased. The combination of the two can achieve the effect of a floating pressing plate 2001, while ensuring that the tape is flattened and the tape is not damaged.
