Description

The present invention relates to a packaging technology for electronic components, and more particularly to a sealing machine.

  In order to continuously supply electronic components to an automated manufacturing process, it is common to package electronic components equidistantly in a receiving space within the carrier band by a coiled carrier band packaging technique. Thus, in addition to being applicable to the manufacturing process of an automated machine, it is also possible to appropriately protect and transport the packaged electronic components. For this reason, the coil-type carrier band packaging technology is widely used in the electronics industry.

  In the conventional coil-type carrier band packaging technique, a lower band in which a large number of housing spaces are provided at equal distances is used as a packaging body, and a film-like upper band is sealed to the lower band. Thereby, each said accommodation space is sealed and the electronic component is accommodated in the inside of each said accommodation space. The sealing of the upper band and the lower band is achieved by an adhesive technique. The pressure-sensitive adhesive technology is such that one side of a pressure-sensitive adhesive layer composed of pressure-sensitive adhesive or a pressure-sensitive adhesive such as hot melt is bonded to one side of the upper band, and a release layer is attached to the other side of the pressure-sensitive adhesive layer By this, it is possible to avoid the adhesion of the adhesive layer to the foreign matter or the mutual adhesion of the adhesive layer.

  When packaging electronic parts with the above, the coiled upper band and lower band are respectively assembled to the sealing machine of Patent Document 1 or Patent Document 2, whereby the upper band and the lower band are assembled. After moving along different movement paths, entering the sealing mechanism in synchronism and being sealed, the sealed carrier band can be taken up by the carrier band receiving shaft. The upper band needs to remove the release layer before entering the sealing mechanism. Thereby, in the sealing mechanism, the adhesive layer is pressed and adheres to the lower band. The removed release layer is wound up by a release layer winding shaft. Thus, in addition to avoiding scattering of the release layer, it is also possible to provide a force for removing the release layer.

  Conventional carrier band technology, packaging technology, and sealing machines are widely used and are ancillary technologies of the electronics industry, so there is little research and development in this technical field. In order to solve the above problems, the applicant of the present application has studied the prior art and found that the prior art adhesive technology is not ideal. This is because it is necessary to adhere the release layer synchronously when the adhesive layer is adhered to the upper band in advance, so that the production of the upper band is extremely complicated. In addition, since the upper band and the lower band are sealed in a large number of accommodating spaces, it is possible to adhere the upper band only around the lower band accommodating space, that is, the upper band and the lower band. Sealing is not complete. Although the upper band and the lower band are partially sealed, the adhesive layer is applied to the entire surface of the upper band, so that the adhesive layer is wasted and the production cost is increased.

  In order to solve the above problem, it is possible to reduce the amount of adhesive used by providing adhesive layers on both edges in the width direction of the surface of one side of the upper band, thereby reducing the production cost. It is possible. The above technique is proposed by Patent Document 3, for example. In Patent Document 3, an upper band having pressure-sensitive adhesiveness is proposed, and it is possible to reduce the production cost by reducing the application area of the adhesive, but the upper band, the adhesive layer, and the release layer are three layers. You cannot escape from the structure. For this reason, the manufacturing process of the upper band cannot be effectively simplified, and the production cost cannot be significantly reduced.

Example 1
Please refer to FIG. 1 to FIG. 1 is a perspective view showing a first embodiment of the present invention, FIG. 2 is a perspective view showing a part of the first embodiment of the present invention, and FIG. 3 shows an urging mechanism of the first embodiment of the present invention. FIG. 4 is a plan view showing a part of the first embodiment of the present invention. The sealing machine 20 of the present embodiment includes a base 21, a lower band receiving part 22, an upper band receiving part 23, an upper band direction guiding part 24, a crimping mechanism 25, a carrier band receiving part 26, and an urging force. Mechanism 27.

Specific technical contents of the pedestal 21, the lower band receiving part 22, the upper band receiving part 23, the upper band direction guiding part 24, the crimping mechanism 25 and the carrier band receiving part 26 are disclosed in Taiwan Utility Model No. 297383 of Patent Document 1 and Since it is similar to the technical content of Chinese Patent No. 201020678528.1 in Patent Document 4, each component member belonging to the prior art will be briefly described.

The pedestal 21 is used as a base of the sealing machine, can appropriately provide power, and has a work table 211 having a rectangular shape installed horizontally. When the lower band 11 is moved by the strip-shaped groove of the work table 211 so that the opening of the storage space faces upward, an electronic component is placed on the surface above the work table 211 to accommodate a large number of the lower band 11. Each space 112 can be entered. In other words, the lower band 11 continues to move along the longitudinal direction by being driven by the power from the pedestal 21 in the strip groove with the surface of the work table 211 as a transition plane.

The lower band receiving portion 22 has an axial shape, one end is fixed to the pedestal 21, and is positioned outside one end in the longitudinal direction of the work table 211. The lower band 11 having a coil shape is inserted into the lower band receiving portion 22 and can rotate around the lower band receiving portion 22. Thus, the lower band 11 can pass through the transition plane continuously.

The upper band receiving portion 23 has an axial shape, one end is fixed to the pedestal 21, and is positioned at an appropriate location above the table surface of the work table 211. Thus, the upper band 12 having a coil shape is inserted into the upper band receiving portion 23. One end of the upper band 12 is guided and can move in the direction of the transition plane.

The upper band direction guide portion 24 is generally a guide rod, the axis of which is parallel to the axis of the upper band receiving portion 23, and one end of which is provided on the base 21. It is possible to guide the direction of transition of the upper band 12. The upper band direction guide portion 24 guides the upper band 12 and can move so as to be substantially parallel to the transition plane.

The pressure-bonding mechanism 25 includes a roller type, a needle type, and a sealing blade type. In this embodiment, the roller type will be described as an example. Of course, the present invention is not limited to these. In other words, the crimping mechanism 25 includes rollers 251 and 252 that are parallel to each other with a certain gap. One end of each of the rollers 251 and 252 is provided on the pedestal 21, is located at the other end in the longitudinal direction of the work table 211, and corresponds to one side of the upper band direction guide portion 24. The upper band 12 turned by the upper band direction guide unit 24 and the lower band 11 that has passed through the work table 211 are in parallel with each other and enter between the rollers 251 and 252 at the same time. The carrier band 10 is formed by being crimped by a crimping force of 252 rolling.

Since the carrier band receiving portion 26 has an axial shape and is located on the side away from the lower band receiving portion 22 of the base 21, the crimping mechanism 25 is interposed between the upper band direction guiding portion 24 and the carrier band receiving portion 26. positioned. One end of the carrier band receiving portion 26 is provided on the pedestal 11 and winds up the carrier band 10 that is crimped to the crimping mechanism 25. The force of winding the carrier band 10 of the carrier band intake portion 26 is caused by rotating the carrier band intake portion 26 by the power provided by the pedestal 11 and rotating the carrier band intake portion 26 at the same time. This is a force for shifting the lower band 11 and the upper band 12 in synchronization.

The urging mechanism 27, which is the main technical feature of the present embodiment, may adopt a conventional dispensing technique. The urging mechanism 27 is provided on the pedestal 21, is located above the transition plane, and is adjacent to the side of the upper band direction guide portion 24 away from the crimping mechanism 25. Thus, it is possible to attach an adhesive to the upper surface of the lower band 11 that is moving horizontally. Specifically, the urging mechanism 27 has at least one pressure-sensitive adhesive supply unit 271 that can control the flow-out amount of the pressure-sensitive adhesive and includes a container including four tubes. The adhesive supply part 271 is located above the transition plane. The two urging ends 272 provided at a distance communicate with the adhesive supply unit 271 and face the upper surface of the lower band 11, so that the adhesive contained in the adhesive supply unit 271 It can be quantitatively attached to the upper surface of the lower band 11. In this way, the lower band 11 moves on the transition plane, moves out of the range of the work table, and lowers the adhesive by the urging mechanism 27 before entering the lower portion of the upper band direction guide portion 24. It is possible to quantitatively attach to the upper surface of the band 11. Accordingly, when the lower band 11 enters below the upper band direction guide portion 24, the lower band 11 adheres to the turned upper band 12, and can be closely adhered to the upper band 12 by the crimping force of the crimping mechanism 25. Is possible.

The upper band 12 is a general resin film, for example, a monolayer film such as an oriented polypropylene (OPP) film, a cast polypropylene (CPP) film, or a polyethylene terephthalate (PET) film, and packaging and storage of electronic components. If necessary, an appropriate metal material may be added to the film, and the upper band body 121 is provided without the adhesive layer and the release layer. The two tear lines 122 are provided on the upper band main body 121 so as to be spaced apart from each other along the longitudinal direction of the upper band main body 121. Each tear line 122 is formed by a processing technique such as laser cutting, but since these processing techniques are well-known techniques, description thereof is omitted.

The height of the adhesive supply unit 271 can be changed according to the situation. The distance between the biasing ends 272 can be adjusted according to the width of the lower band. The technical contents of these changes and adjustments will not be further described, but those skilled in the art can easily understand and implement them.

The adhesive can be attached to the lower band 11 of the urging mechanism 27 by using a constant flow rate or a variable flow rate method. The adhesive is linearly and continuously discharged on the upper surface of the lower band 11. Alternatively, the adhesive may flow out intermittently at a fixed time. Even if any of the above is adopted, the upper band 12 and the lower band 11 can be adhered. The use of the adhesive is intended to adhere the upper band 12 and the lower band 11, and the upper band 12 and the lower band 11 are separated by the tear lines 122, that is, the upper band 12 is broken. Thus, the upper band 12 and the lower band 11 can be separated. As long as the purpose of sticking the upper band 12 and the lower band 11 can be achieved, the components of the pressure-sensitive adhesive are not limited.

Each urging end 272 is capable of attaching an adhesive to a portion close to both edges in the width direction of the upper surface of the lower band main body 111, and faces the outside of the two tear lines 122, respectively. . In this way, the compressed carrier band 10 can take out the electronic component by separating the upper band 12 and the lower band 11 by breaking the two tear lines 122.

The configuration of the upper band 12 has been described above. Here, each urging end 272 of the urging mechanism 27 is capable of attaching an adhesive to a position close to both edges in the width direction of the upper surface of the lower band main body 111, and each has two tear lines. It faces the outside of 122.

Specifically, the two urging ends 272 of the urging mechanism 27 have a tube shape, one end communicates with the adhesive supply unit 271, and the other end faces the upper surface of the lower band 11.

On the other hand, the urging mechanism 27 can apply the adhesive to constant flow quantification, variable flow rate, or fixed time quantification, which is the technical content of a conventional dispenser and is familiar with the technology. Since it can be easily understood, the explanation of the urging mechanism 27 is omitted.

FIG. 5 is a perspective view showing a second embodiment of the present invention, and FIG. 6 is a perspective view showing a part of the second embodiment of the present invention. The sealing machine 20 'of the present embodiment has substantially the same technical features as the first embodiment, but is different from the first embodiment in that an adhesive is attached to the upper band.

In this embodiment, in order to attach the adhesive to the upper band, the transition path of the upper band 12 is changed, that is, the surface that adheres to the lower band 11 of the upper band 12 is directed upward, and the biasing mechanism 27 The two urging ends 272 ′ are attached to both ends in the width direction of the surface of the upper band 12, and are then adhered to the lower band 11 with the surface of the upper band 12 facing downward.

The urging mechanism 27 ′ includes a member similar to the first embodiment, and further includes a guide stand 273 ′. The guide base 273 ′ is provided on the base 21 ′, and is located outside the surface on the side away from each urging end of the upper band 12, and on the side away from each urging end of the upper band 12. This is for supporting the upper band 12. The guide base 273 ′ has a base portion 2731 ′ provided on the base 21 ′. A guide groove 2732 ′ having a width that substantially matches the width of the upper band 12 is provided on the upper surface of the base portion 2731 ′. The upper band 12 is positioned by moving the guide groove 2732 ′ with the lower surface thereof facing upward. When the adhesive is applied by the urging end 272 ', the upper band 12 is supported by the guide groove 2732', so that the adhesive can be applied stably and smoothly.

In particular, the following two points will be further described.
(1) Although the tearing machine of said Example is provided with the tear line in the upper band, this invention is not limited to these. In other words, even if the upper band, which is a single layer, is not provided with a tear line, it belongs to the scope of the utility model registration claim of the present invention.

(2) The pressure-bonding mechanism of the above-described embodiment provides a pressure-bonding force for pressing and bonding the upper band and the lower band, but the necessity of the pressure-bonding force varies depending on the type of pressure-sensitive adhesive.
