Description

Technical Field

[0001] The utility model relates to the technical field of SMD component production, in particular to a full-automatic punching and taping integrated machine. Background Art

[0002] SMT is the abbreviation of surface mount technology, which means surface mounting technology. The emergence of SMT has brought about a huge change in electronic products. At present, most PCBs have more or less adopted this low-cost, high-efficiency, and reduced-volume production technology. SMD is the abbreviation of Surface Mounted Devices, which means surface mount devices. The widespread adoption of SMT has promoted the development of SMD. The original socket components have become inevitable to be replaced by SMD components. At the same time, people's requirements for small size and multi-functions of electronic products such as mobile phones and computers have further promoted the development of SMD components towards high integration and miniaturization. At present, in order to meet the needs of high-speed automation of SMT production lines, SMD components are usually packaged and transported with carrier tapes to meet the needs of high-speed development of SMT production lines. As a carrier tape for packaging and transporting SMD components, it is usually composed of a carrier tape with several cavities for accommodating SMD components and a cover tape for closing the cavity opening. The cavity is usually formed in the middle of the width direction of the carrier tape and arranged at equal intervals along the length direction of the carrier tape. The speed of SMD component carrier tape packaging is determined by the speed of loading SMD components into the carrier tape cavity. The traditional operation method is: first, the carrier tape is sent to the working platform of the tape machine through the winding device for positioning; then, the cut pieces of loose SMD components are loaded into the carrier tape cavity manually or by a robot, and finally, the cover tape and the carrier tape are sealed by a hot pressing device to complete the packaging of the SMD components; the above operation methods, one is to use manual loading, which requires a lot of manpower, and the operation and packaging efficiency is low, the cost is high, and it is difficult to guarantee product quality by manual operation. The other is to automatically pick up the material through the robot, and load the cut loose SMD components into the carrier tape cavity; this operation method, because the robot needs a certain time in the movement process, the efficiency of SMD component carrier tape packaging is still low, which cannot meet the needs of high-speed automated production of SMT production lines. In particular, for some punching and cutting products such as shrapnel or nickel sheet, since these products are relatively light and thin, some are only 0.1mm, and the products are either flat, L-shaped or special-shaped, and the products have front and back directions, when this operation method is used to package these products, there are problems such as the vibration plate feeding and jamming, low efficiency in direction identification, and difficulty in feeding and grabbing by the robot. Some products cannot even meet the packaging requirements of the automatic taping machine and can only be packaged manually.

[0003] However, the existing integrated punching and taping machines usually use ejector pins for positioning during taping, which requires additional positioning time each time the process is performed, thereby affecting the processing efficiency. Utility Model Content

[0025] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0026] In the description of the present invention, unless otherwise specified, "multiple" means two or more; the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] See also Figure 1-5 A fully automatic stamping and taping integrated machine includes a positioning platform 1 and a hydraulic cylinder 10. A group of vertical passages with different heights are provided on the surface of the positioning platform 1, and the passages are respectively connected with a material belt 2 and a carrier belt 3. A first limiting bin 4 is provided at the end of the opening of the passage on the surface of the positioning platform 1, and a second limiting bin 6 is connected to the other end face of the positioning platform 1 perpendicular thereto. The material belt 2 enters the passage through the first limiting bin 4 and extends out from the end of the passage, and the carrier belt 3 enters the passage through the second limiting bin 6. A first motor 5 is connected to one end face of the first limiting bin 4, and a second motor 7 is connected to one end face of the second limiting bin 6. The first motor 5 The output end of the second motor 7 is connected to a feeding structure, and the feeding structure is used to transport the material belt 2 or the carrier belt 3. A plurality of support columns 9 for supporting the hydraulic cylinder 10 are connected at the intersection of the edges of the two passages on the top surface of the positioning platform 1. There is a cavity in the support column 9, and a mounting structure is connected in the cavity. The mounting structure is used to install the material of the material belt 2 to the carrier belt 3. The center of the intersection of the two passages on the top surface of the positioning platform 1 is concave downward, and a plurality of second springs 14 are connected to the top of the concave surface, and a convex plate 15 is connected to the end of the second spring 14. A trigger switch 16 is arranged in the concave surface of the positioning platform 1, and a distance sensor 17 is arranged in the concave surface.

[0029] Furthermore, during installation, the material belt 2 is first passed through the first limit bin 4, and it is ensured that the end of the material belt 2 passes through the first limit bin 4. When installing the carrier belt 3, similarly, the carrier belt 3 is passed through the second limit bin 6 to complete the installation. The feeding structure is composed of a rotating roller and a feeding sleeve 8, and the feeding sleeve 8 is made of a material with a high static friction coefficient. During feeding, the rotation speeds of the first motor 5 and the second motor 7 are different, and the rotation speeds correspond to each unit of the material belt 2 and the carrier belt 3, respectively, so that they are gathered at the center of the passage. During tape braiding, the first motor 5 and the second motor 7 respectively drive the rotating rollers at their output ends to rotate. When the rotating rollers rotate, the feeding sleeve 8 at the outer end thereof is driven to rotate, and the other rotating roller is driven to rotate, thereby increasing the contact area between the feeding sleeve 8 and the material belt 2 or the carrier belt 3, thereby ensuring the stability of the feeding.

[0030] Furthermore, there are four support columns 9, and they can be detachably installed on the intersection edge of the passage of the positioning platform 1. The installation structure consists of a first spring 12 and a feeding head 13. The first spring 12 is fixedly installed on the bottom surface of the internal cavity of the support column 9. The end of the first spring 12 is connected to the feeding head 13. The number of the first spring 12 is consistent with the number of support columns 9. The four support columns 9 are provided with through grooves on the side facing the carrier belt 3. The feeding head 13 is in a "convex" shape. The width of the raised part of the feeding head 13 is consistent with the width of the material on the material belt 2, and the edge of the raised part of the bottom surface is sharp, and the middle end of the bottom surface is arc-shaped. The length of the arc-shaped protrusion and the sharp part extending downward is consistent. When the corresponding units of the material belt 2 and the carrier belt 3 are in a vertical area, the hydraulic cylinder 10 is started. The feeding head 13 is pushed to press the material on the material belt 2 into the carrier belt 3. When the output end of the hydraulic cylinder 10 moves downward, it will first contact the feeding head 13, and then the four corners of the feeding head 13 will compress the first spring 12 respectively. When the feeding head 13 is pressed down to the top of the material belt 2, the sharp edge of the raised part of the feeding head 13 will cut off and separate the material on the material belt 2 from the material belt 2. At the same time, the arc-shaped part of the raised center of the feeding head 13 will push the material into the carrier belt 3. During the pushing process, the raised arc-shaped part of the feeding head 13 does not contact the material belt 2, thereby completing a unit of braiding. In addition, since the feeding head 13 needs to contact the output end of the hydraulic cylinder 10 for a long time and multiple times, it is necessary to ensure that the feeding head 13 is made of high-strength metal.

[0031] Furthermore, during the rotation of the first motor 5 and the second motor 7, when the first unit of the carrier tape 3 is about to be transported to the center of the positioning platform 1, it will first contact the convex plate 15. At this time, the material belt 2 is directly above the carrier tape 3, providing pressure, so that the first unit of the carrier tape 3 compresses the second spring 14 through the convex plate 15. When the second spring 14 is compressed, the distance sensor 17 senses that the distance between it and the receiving target is shortened. When the first end of the first unit of the carrier tape 3 passes through the convex plate 15, its first unit will be stuck out by the top plate 15. At this time, the distance sensor 17 is closer to the receiving target. The distance between the two ends increases, and the electrical signal is transmitted to the hydraulic cylinder 10, the first motor 5 and the second motor 7 to stop feeding the first motor 5 and the second motor 7, and at the same time start the hydraulic cylinder 10 to perform the feeding operation to complete the first unit of taping. When the hydraulic cylinder 10 presses the material on the material belt 2 downward, the material compresses the convex plate 15 so that the convex plate 15 contacts the trigger switch 16, and then starts the first motor 5 and the second motor 7 to continue feeding. The above steps are repeated to complete the taping, thereby reducing the positioning stagnation time required for conventional positioning and greatly improving the processing efficiency.

[0032] Furthermore, during the feeding process, it is necessary to ensure the stability of the middle part to avoid deviation. A pressure roller 11 is rotatably connected to the end surface between the support columns 9. The direction of the pressure roller 11 is set parallel to the direction of the carrier belt 3, thereby ensuring the compression of the material belt 2.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
