In conjunction with the automatic = assembly process, when the electronic component is taken, the entire device L (4) is taken as the most commonly used red 22 in the current practice, and the electronic component is taken out. The cross-sectional structure of the sealing device of FIG. 1Bfsn shows that the loading belt 30 includes a face-down: the ugly-containing belt 30 and the download belt 20; the pocket U is used to accommodate the inner surface of the electricity 32°. The uploaded tape structure shown. In the winding of the package, the electronic-calling surface 32 is a closed surface formed by a smooth surface junction. The sealing surface of the sub-element 40 is adhered to the carrier tape 30. In practical applications, since the sealing tape 10 involves the bonding and peeling process, since the loading tape 30 is separated from the downloading tape 2, if the adhesive force is low and the deviation is not uniform, various problems will occur. . For example, when the viscosity is biased, the easy-to-storage process is impacted by an external force, causing the download tape 2〇 to be loosened from the loading tape, and the electronic component 40 is scattered; when the viscosity is too high, the loading tape 30 is In the stripping procedure, the component surface 42 of the electronic component 40 that is placed in the pouch 22 is adhered to the inner surface 32 of the carrier tape 32 for operation and listening. ~Ί In addition, when the sealing tape is turned over and the electronic component 4 is placed on the closed space, the electronic component 4G is also large in size, resulting in "the electronic component 4 of the inner surface 32 of the carrier tape 30 is not easily defective. [Invention] The uploading is to provide a modified structure of the sealing tape, which is capable of providing a protective structure as a stopper, and providing a functional surface for fixing the electronic component. The stop and the electronic component 3 further reduce the load on the upper _smooth table (four) read Xu yuan (four) secret surface reduction / equipment and can operate efficiently. The force 'at least the sealing tape structure contains the upper solution and the download tape; download The belt has a 4 nano-electronic tree. The connecting surface is bonded to the loading belt. The recessed portion 4 201245008 ft is loaded with a square rafter. The loading belt has an inner surface facing the download belt, wherein the upper portion has a stopper shaft _ surface above and convex The inner surface of the inner surface is formed into at least a convex structure, which is distributed in the longitudinal direction of the t. In addition, the convex rib structure is along the short side of the download tape; The portion of the pocket may have a smaller width. In another embodiment, the blocking portion may be formed as at least a bump structure spaced apart in the longitudinal direction and corresponding to the pocket portion of the download tape, respectively. The block structure has a contact surface facing the pocket portion, and the contact surface includes Coarsening = In the embodiment, the shape of the roughened structure may be a plurality of circular bumps: a smudged pit, a plurality of staggered embossings, a plurality of straight stripes, or a d-indented circular hole structure. = The structure has a small width along the portion of the cross-sectional short-side direction. The strict clothing [embodiment] The present invention (4) provides a modified structure of the sealing tape. ::: The structure can be used for the surface adhesion of the light-emitting diode Sealing;:: Use: Other electronic supplements ^ County." For _ Hi Figure 3 is a bottom view of the uploading tape 300 of the present invention and a short side cross-sectional view of the sealing tape 100 including the household carrying tape 200. As shown in Fig. 3, the W-shirt belt 200 has at least one pocket portion 202 arranged along the length of the download tape 200, and each pocket portion 202 is for accommodating an electronic component 400. In Fig. 3, in the downloading of the thin bag portion 202, there is a relative side of the second side of the 201245008 204. The part of the uploading unit 2G2 is the inner surface of the J-Xing Shangzhan belt 300. A recessed portion is formed between the pockets 202. The self-checking and unloading of the belts and the adjacent pockets of the W Ϊ from the connecting surface 208 away from the loading belt 3〇〇20" I. That is, the recessed portion 2〇6 is formed in The pocket portion 202 is connected to the connecting surface and along the longitudinal direction of the downloading belt 2〇2. The loading belt has a second surface facing the downloading belt 200 and the loading belt 300 is shown in the aligning surface inner surface 12 and FIG. The stagnation portion 3〇4 is formed on the inner surface 3〇2. The ΟΜ ΟΜ 304 system protrudes from the inner surface 3〇2 and protrudes toward the capsular portion 2〇2. As shown in Fig. 2, the rib rib structure 304 is continuously distributed along the longitudinal direction of the 300, wherein the rib structure has a point of two points. Please also refer to the sectional view of the sealing tape in Figure 3. Figure 3 shows a section of the upper and lower strips 200 along the short side. The material with 3 turns is usually made of polyethylene terephthalate (p〇lyethylene ^_alate, PET) and has an antistatic polyester tape carrier. The inner surface of the loading belt 300 is viscous for bonding to the joint faces 208 on both sides of the download tape 200. In this embodiment, the striker portion 3〇4 is a rib structure that protrudes toward the pocket portion of the download belt. The rib structure is applied to the inner surface 302' and further processed by stamping or rolling forming, so that more than one rib structure of the bump shape (ie, the stopper portion 304) is formed in the longitudinal direction and Has a sufficient thickness. As shown in FIG. 3, the recessed portion 206 between the connecting surface 208 of the download tape 200 and the both sides of the bag portion 202 is distributed along the longitudinal direction of the download tape 202, and is separated from the connecting surface 208 toward the loading tape 3 The direction is back. In this embodiment, the retracting height is preferably equal to the thickness of the rib structure (ie, the stopper portion 304) of the loading belt 3, so that the rib structure can be accommodated after the loading belt 3 黏 is bonded to the downloading belt 2 (8). In the recess 206. In other embodiments, the thickness of the rib structure 201245008 may also be slightly less than the height at which the recess 206 is retracted. As shown in FIG. 3, the pocket portion 202 of the carrier tape 200 is used to house the electronic component 400 with a side wall 204 around the pocket 202. In this embodiment, the supporting portion 304 having the shape of the rib structure is disposed corresponding to the recessed portion 2〇6 of the downloading tape 2〇〇. However, in other embodiments, the stop portion 304 may also be disposed between the side walls 204. As shown in Fig. 3, the bonded tape 300 is combined with the recess 206 of the download tape 200, the side wall 204, and the pocket portion 2〇2 to form a closed space. By the rib structure (i.e., the stop portion 304) of the tape 300, the contact area between the inner surface 302 of the tape 300 and the tape 2 can be reduced. That is, by contacting the bumps of the rib structure with the electronic component 400, the contact area between the inner surface 3G2 of the carrier tape 3 and the electronic component can be reduced, and the electrons can be restrained by the bump contacting the surface of the electronic component. The displacement of the component ,, in turn, achieves the effect of fixing the electronic component. Thus, it is possible to avoid the problem that the surface of the electronic component 4 is adhered to the smooth inner surface of the carrier tape 3 (i.e., the inner surface portion of the stopper portion 304) when the sealing tape is unwound. When the carrier tape is peeled off 3 times in the process, the residual adhesive force of the carrier tape 3〇〇 and the electronic component 400 can be reduced, and the convenient adsorption terminal can be used to take out the electronic component 4 from the pocket portion 202 of the download tape 2, and It can reduce the load on the equipment and operate efficiently. Further, the provision of the stopper portion 3〇4 has an effect of stably conveying the electronic component 400, and the electronic component 4 is prevented from being damaged by vibration during the conveyance. In other embodiments, the rib structure may be designed differently depending on the size of the electronic component 400. For example, for a smaller size electronic component 400, a single elongated rib structure corresponding to the download tape 2 (nine) is short. The above effect can also be achieved by the middle position of the side profile. 4A and 4B show the variation of the stopper portion 3〇4 of the rib structure. The example in which the rib structure is along the short side direction of the carrier tape 300 can be differently shaped to meet different needs. For example, the rib structure in FIG. 3 has a circular arc shape along the short side direction of the loading belt 300. In the embodiment shown in FIG. 4A, the rib structure has a triangular shape along the short side direction of the loading belt 300. . In the embodiment shown in Fig. 4B, the cross-sectional shape of the rib structure may also be trapezoidal. That is, the rib structure (i.e., the cross-sectional shape of the stopper portion 3 in the short-side direction of the download tape 2) may have a smaller width in a portion close to the pocket portion 2〇2 to further reduce contact with the electronic component 400. In this case, the number and shape of the rib structure can be differently designed according to the size of the electronic component 400. It should be noted here that <Tianchuan 4 is not limited to the convexity extending along the longitudinal direction of the loading belt 3〇〇. Fig. 5 is a bottom view of another embodiment of the loading belt 3. As shown in Fig. 5, the inner surface 3〇2 of the loading belt 300 has an elongated strip structure as a stopper 3〇4 The bump structures are arranged at intervals along the longitudinal direction of the loading belt 3 (8) and respectively correspond to the pocket portion of the download tape 2 加 plus 2. In this embodiment, the bump structures are arranged in pairs =, convexly the same capsule The bag portion is moved. Referring to the sealing tape of Fig. 6; Fig. 6 is not a cross section of the loading belt 3〇〇 and the download belt 2〇〇 along the longitudinal direction. The inner surface of the loading belt 300 includes the support 3 The #n stop portion 304 of the portion n is a pair of bump structures, and the convex downloading structure 200 has a thickness of a bump structure. The process is formed by pressing or rolling into a crucible. In this embodiment, the upper layer is preferably thicker than the download tape 20. The connecting surface 2〇8== electrons enable the bump structure to be pressed against the upper download tape while借此 The bump structure stabilizes the electronic component 111, and the smaller contact area is in contact with the surface of the electronic component 400. In the embodiment of the light 201245008, the thickness of the bump structure can also be slightly smaller than the thickness of the download ribbon i to The height difference of the surface of the electronic erroneous surface. In this embodiment, the cross-sectional shape of the convex ridge along the longitudinal direction of the loading belt is a circular arc shape. In other embodiments, the convex structure is along the carrying line. The cross-sectional shape in the long-side direction may also have different designs depending on the requirements of the electronic components, such as triangles, trapezoids, or other geometric shapes or irregularities. As shown in Fig. 6, the block structure of the bump structure 3〇 The 4 series 'corresponds to the pocket portion 202 of the download tape set' and the pair of bump structure positions are located between the side walls 204 of the bag portion 202. In other embodiments, the stop portion 3〇4 A single long strip of bumps can be placed along the long side of the download tape 200 Corresponding to the intermediate position of the pocket portion 202, as shown in Fig. 7. Fig. 7 shows the face of the uploading belt 300 and the download belt in the short side direction. The inner surface 302 of the loading belt 300 includes the supporting portion 3〇. 4. In this embodiment, the supporting portion 304 is a bump structure that is convexly directed to the sac portion 2G2 of the download tape 2 。. As shown in the cross-sectional view of Fig. 7, the recessed portion 206 is connected from the download tape. The height of the surface 208 retracted is equal to the thickness of the bump structure of the uploading surface, so that the bump structure can be accommodated in the capsule "卩202" and resists the electronic component 4〇〇 after the loading tape and the τ fresh bonding. In other embodiments, the thickness of the bump structure may also be slightly smaller than the height of the bird in the recessed portion. The stopper portion 3G4 of the bump structure is disposed corresponding to the pocket portion 2〇2 of the lower cake, and the length thereof is between Between the recessed portions 206 of the pocket portion 202. As shown in FIG. 7, the contact surface 3〇6 of the stopper portion 3〇4 (e.g., the bump structure) has a roughened structure 308. The roughened structure 3〇8 is subjected to surface processing by using the three-layer embossing method of the embossing (four) embossing to form an image bearing tape having a roughened surface. Thereby, the bump structure is made into the electronic component 400, and the roughened structure is brought into contact with the surface of the electronic component 4(8) 201245008 with a small contact area, thereby reducing the chance of adhesion of the carrier tape to the electron tree surface. When the automated device peels off the carrier tape 300, the adhesion of the carrier tape 3〇〇 to the electronic component 400 is lowered to improve the process yield and to produce more efficiently. An embodiment of a roughened structure 308 is shown in FIG. 8A. In this embodiment, the roughened structure 308 forms a plurality of circular bump arrangements on the contact surface 306. However, in other embodiments, the roughened structure 3〇6 may also form a plurality of circular pit arrangements ‘or alternatively, circular bumps and circular pits may be used to form an irregular distribution. In addition, in the embodiment illustrated in Figure 8B, the roughened structure 3〇6 forms a plurality of interlaced diagonal embossments. Figure 8C shows a plurality of straight embossed structures. The figure shows a contact hole 306 of the bump structure that is recessed in a direction away from the download tape 200; in other embodiments, the number of holes can be adjusted to the size of the electronic component 4A. Further, the stopper portion 304 of the loading belt 300 is not limited to the above-described rib structure extending in the longitudinal direction of the loading belt 3 or the bump structure extending in the short side direction. That is, the stopper portion 304 may be distributed on the uploading The strap 300 corresponds to a single or complex discrete projection in the inner surface region of the pocket portion 202 of the download strip 200.
