Description

Technical Field

[0001] The present invention belongs to the technical field of conveying, and specifically relates to the transportation of objects, and particularly relates to a tape conveying device and a conveying method for glass substrate packaging materials. Background Art

[0002] In the field of glass substrate packaging, a tape-type conveying device is the core equipment for realizing automatic chip packaging. In the prior art, the tape usually adopts a wound-up design, and realizes cyclic conveying through the cooperation of a unwind reel and a winding roller, but there are the following technical bottlenecks: Curvature accumulation and interlayer bonding defects. Traditional tapes mostly adopt hard polymer materials (such as PC, PET). Although they have a certain toughness, when the tape is repeatedly wound around the outer wall of the unwind and wind-up reels, the curvature accumulation effect of the inner layer of the tape is significant. When the tape is released from the unwind reel, the innermost layer of the tape has undergone the largest bending deformation, and its molecular chains have irreversible orientation, resulting in a memory effect of the material. When winding again, the original innermost layer of the tape cannot be closely attached to the adjacent layer due to curvature mismatch, forming a gap, which causes the tape to loosen or even the chip to displace.

[0003] In the prior art, the tail of the tape is usually manually attached to the adjacent layer of the wound tape. However, during manual attachment, the operator locates the tail of the tape based on experience, and it is easy to cause misalignment during attachment due to hand shaking or visual deviation, resulting in interlayer gaps or tape loosening, exacerbating the curvature accumulation effect; moreover, when the hand directly touches the tape or the chip area, it is easy to introduce pollutants such as grease and dust, causing surface contamination of the glass substrate or chip, and reducing the packaging yield. Therefore, how to solve the problem of poor interlayer bonding of the tape caused by the curvature accumulation effect is a technical problem that urgently needs to be solved in this field.

[0004] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of this application. Therefore, the above description is not considered to constitute information on related technologies. Summary of the Invention

[0028] It has been found through research that in the related art, in the field of glass substrate packaging, a tape-type conveying device is the core equipment for realizing automated chip packaging. In the prior art, a flexible tape usually adopts a rewinding design and realizes circular conveying through the cooperation of a unwind reel and a take-up roller, but there are the following technical bottlenecks: Curvature accumulation and interlayer bonding defects: In traditional tapes, hard polymer materials (such as PC and PET) are mostly used. Although they have certain toughness, when the tape is repeatedly wound around the outer wall of the pay-off and take-up reels, the curvature accumulation effect of the inner layer of the tape is significant. When the tape is released from the pay-off reel, the innermost layer of the tape undergoes the largest bending deformation, and its molecular chains undergo irreversible orientation, resulting in a memory effect in the material. When rewound again, the original innermost layer of the tape cannot be closely bonded to the adjacent layer due to curvature mismatch, forming a gap, which causes the tape to become loose or even the chip to shift.

[0029] In the prior art, the method of manually attaching is usually adopted to attach the tail of the tape to the adjacent layer of the wound tape. However, during manual bonding, the operator locates the tail of the tape based on experience, which is prone to bonding misalignment due to hand shaking or visual deviation, resulting in interlayer gaps or tape loosening, and aggravating the curvature accumulation effect. Moreover, when the human hand directly touches the tape or the chip area, it is easy to introduce pollutants such as grease and dust, causing surface contamination of the glass substrate or the chip, and reducing the packaging yield. Therefore, how to solve the problem of poor interlayer bonding caused by curvature accumulation is a technical problem that urgently needs to be solved in this field.

[0030] Regarding the defects and their causes of the above solutions, they are all the results obtained by the inventor after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure by the present disclosure should all be the contributions made by the inventor during the process of this disclosure.

[0031] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0032] The following will describe in detail some embodiments of the present invention with reference to the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0033] Such as Figures 1 to 7As shown, at least one embodiment provides a material tape conveying device for glass substrate packaging, comprising: an unwinding disk 1, which is rotatably arranged above a conveying device 2 and is used to wind a material tape 5; a positioning plate 31 is arranged on one side of the conveying device 2, and the unwinding disk 1 is rotatably arranged at the end of the positioning plate 31. A patch device 3, which is arranged on one side of the conveying device 2; the patch device 3 extends along the length direction of the conveying device 2, and the patch device 3 is located above the material tape 5, and is used to flatten the passing material tape 5. A driving disk 4, which is rotatably arranged at one end of the conveying device 2 away from the unwinding disk 1 and is located below the material tape 5; a driving motor is arranged on one side of the conveying device 2, and the driving disk 4 is sleeved on the end of the rotating shaft of the driving motor, and the driving motor is used to drive the driving disk 4 to rotate. When the driving disk 4 rotates, the material belt 5 is driven to move horizontally until the tail of the material belt 5 is separated from the patch device 3; the patch device 3 is suitable for applying the protective sheet 34 to the side wall along the side edge of the tail of the material belt 5, so that when the material belt 5 is rolled up, the protective sheet 34 makes the tail of the material belt 5 fit closely with the adjacent layer of the rolled-up material belt 5. By arranging the patch device 3 on one side of the conveying device 2, when the tail of the material belt 5 is separated from the linkage block 32, the linkage block 32 moves downward to apply the protective sheet 34 to the side wall of the tail of the material belt 5; and the arrangement of the protective sheet 34, when the material belt 5 is rolled up again, the protective sheet 34 makes the tail of the material belt 5 fit closely with the adjacent layer; avoiding the generation of a gap between the tail of the material belt 5 and the adjacent layer.

[0034] Reference Figure 3 The patch device 3 includes: a positioning plate 31, which is arranged on one side of the conveying device 2 and is located above the material belt 5; the positioning plate 31 is rectangular, and the length direction extends along the moving direction of the material belt 5. A linkage block 32, which is arranged on the positioning plate 31 near the material belt 5, and the bottom wall abuts against the material belt 5; a material tray 33, which is slidably arranged on the bottom wall of the positioning plate 31, and is used to carry a protective sheet 34; the material tray 33 is slidably arranged along the width direction of the positioning plate 31, and one end protrudes from the positioning plate 31. When loading, the protective sheet 34 is horizontally placed on the material tray 33, and one end protrudes from the material tray 33. The edge of the protective sheet 34 abuts against the linkage block 32; wherein, when the material belt 5 moves horizontally toward the driving disk 4 through the positioning plate 31, the vertical section 322 of the linkage block 32 abuts against the surface of the material belt 5, and the effect of flattening the material belt 5 is achieved. When the material belt 5 moves to the point where its end is separated from the linkage block 32, the linkage block 32 moves downward to pull the protection sheet 34 to move downward synchronously, so that the protection sheet 34 is attached to the side wall of the tail of the material belt 5. After the protection sheet 34 is attached to the surface of the material belt 5, the material belt 5 continues to move toward the driving disk 4, and the heat-sealing roller 22 heat-seals the protection film on the surface of the material belt 5. At this time, the protection sheet 34 is located between the material belt 5 and the protection film. When the protection film needs to be torn off, the protection film facilitates the tearing off of the protection film from the material belt 5.

[0035] Continue to refer to the attached Figure 3, the linkage block 32 includes a horizontal section 321 and a vertical section 322, and the vertical section 322 is perpendicular to the horizontal section 321; the bottom wall of the vertical section 322 abuts against the strip 5, and the bottom wall of one side of the horizontal section 321 is attached to the protective sheet 34. A receiving groove 310 is formed in the positioning plate 31, and the width of the receiving groove 310 is not less than the width of the horizontal section 321; a return spring 311 is arranged in the receiving groove 310, the lower end of the return spring 311 abuts against the horizontal section 321, and the return spring 311 is adapted to push the horizontal section 321 so that the vertical section 322 abuts against the surface of the strip 5.

[0036] Refer to the appendix again Figure 3 , the protective sheet 34 is arranged in a staggered manner with the linkage block 32, and the overlapping part of the protective sheet 34 and the linkage block 32 is 1 / 5 of the total length of the protective sheet 34. When the strip 5 moves horizontally towards the driving disc 4 through the linkage block 32, a part of the protective sheet 34 is located on the strip tray 33, and the other part of the protective sheet 34 is suspended above the strip 5, and the overlapping part of the surface of the protective sheet 34 and the linkage block 32 is attached to the bottom wall of the horizontal section 321. When the strip 5 moves to be separated from the linkage block 32, the return spring 311 pushes the horizontal section 321 downward, and the horizontal section 321 pushes the protective sheet 34 to move downward synchronously. If the linkage block 32 moves downward until the vertical section 322 abuts against the conveying device 2, at this time the horizontal section 321 pushes the protective sheet 34 towards the strip 5 until the protective sheet 34 is attached to the surface of the strip 5. The bottom surface of the protective sheet 34 has adhesiveness and the whole has a certain thickness and hardness, that is, after adhering to the side wall of the strip 5 in the Figure 6 state, the protective sheet 34 still remains parallel to the strip 5, and the end away from the strip 5 will not droop downward due to gravity. The material of the protective sheet 34 is coated paper, and the surface is covered with a plastic film (PP / PET); the bottom surface of the protective sheet 34 is microsphere glue, and the microsphere glue is composed of microspheres, and the adhesiveness is controllable, and the colloid can fall off completely when peeled off. The surface of the strip tray 33 is a smooth surface, and the adhesiveness is weak when the protective sheet 34 (microsphere glue coated paper) is adhered to the strip tray 33.

[0037] The protective sheet 34 extends along the length direction of the strip 5, and the width of the protective sheet 34 attached to the surface of the strip 5 is 1 / 3 of the total width of the protective sheet 34. When the strip 5 is wound up again, a pressing roller is slidably arranged on the side wall of the winding disc, and the pressing roller abuts against the outer wall of the outermost layer of the wound strip 5. When the protective sheet 34 at the tail of the strip 5 moves to abut against the pressing roller, the pressing roller squeezes the protective sheet 34 so that the protective sheet 34 is closely attached to the adjacent layer of the inner strip 5, avoiding the loosening of the strip.

[0038] Refer to the appendix Figure 4, a protective film roll 21 is rotatably arranged above the conveying device 2, and the protective film extends from the protective film roll 21 to the surface of the laminating tape 5; a heat-sealing roller 22 is rotatably arranged above the conveying device 2, and the heat-sealing roller 22 is adapted to heat-seal the protective film to the surface of the tape 5. The width of the heat-sealing roller 22 is smaller than the width of the protective film.

[0039] Refer to the appendix again Figure 4 , a plurality of positioning holes 50 are evenly distributed along the length direction of the tape 5; a plurality of positioning posts 40 are evenly distributed circumferentially on the outer wall of the driving disc 4, and the positioning posts 40 are adapted to be inserted into the positioning holes 50; wherein, when the heat-sealing roller 22 heat-seals the protective film to the surface of the tape 5, the edge of the protective film is located above the positioning hole 50. The edge of the protective film near the positioning hole 50 is not heat-sealed by the heat-sealing roller 22. Figure 4 The dotted line along the length direction of the hopper in the figure is the edge line of the heat-sealing of the protective film, and the protective film located above the positioning hole 50 is not heat-sealed. A detection device 23 is arranged above the conveying device 2, and the detection device 23 is located above the driving disc 4; wherein, when the driving disc 4 drives the tape 5 to move horizontally, the positioning post 40 is inserted into the positioning hole 50 and pushes the protective film at the edge upward; if the upward tilting amplitude of the protective film edge is less than the normal range, the heat-sealing of the protective film edge is qualified, and if the upward tilting amplitude of the protective film edge is greater than the normal range, the heat-sealing of the protective film is unqualified, and there is a risk of incomplete heat-sealing. The detection device 23 detects whether the heat-sealing of the protective film is qualified by detecting the tilting amplitude of the protective film.

[0040] Refer to the appendix Figure 5 , the driving disc 4 drives the tape 5 to move away from the unwinding disc 1 until the tail of the tape 5 disengages from the unwinding disc 1, and the tail of the tape 5 passes through the positioning plate 31 until the tail of the tape 5 disengages from the linkage block 32. At this time, the linkage block 32 moves downward; Figure 5 F1 in the figure represents the downward movement direction of the linkage block 32. When the linkage block 32 moves downward, it drives the protection piece 34 to move downward synchronously, so that the protection piece 34 adheres to the side edge of the tape tail. Figure 5 F2 in the figure represents the moving direction of the tape 5.

[0041] The working principle is as follows: Refer to the appendix Figure 3 , when the tape 5 moves horizontally along the conveying device 2, the vertical section 322 of the linkage block 32 abuts against the surface of the tape 5. At this time, part of the protection piece 34 is located on the material tray 33, and the other part of the protection piece 34 is suspended above the tape 5, and the upper surface of the protection piece 34 abuts against the horizontal section 321.

[0042] Refer to the appendix Figure 6, the tape 5 is conveyed until it is separated from the linkage block 32, and the return spring 311 pushes the horizontal section 321 downward, and the horizontal section 321 pushes the protection piece 34 to move downward synchronously. Since the protection piece 34 partially overlaps with the linkage block 32, when the linkage block 32 moves downward to the maximum stroke, the protection piece 34 can be attached to the surface edge of the tape 5, and the final attachment effect is as shown in Figure 7 shown. At this time, one side of the protection piece 34 adheres to the surface edge of the tape 5, and the other side adheres to the surface of the material tray 33. At this time, the material tray 33 moves away from the tape 5 to facilitate the separation of the protection piece 34 on the material tray 33 from the material tray 33. When the material tray 33 falls off, the linkage block 32 still presses above the protection piece 34 until the material tray 33 is separated from the protection piece 34. At this time, the protection piece 34 is adhesively attached to the surface edge of the tape 5 in a parallel shape.

[0043] Figure 6 In the figure, F1 represents the moving direction of the return spring 311 pushing the linkage block 32 downward.

[0044] At least one embodiment provides a conveying method of a conveying device, and the conveying method includes: The tape 5 extends from the unwinding reel 1 to the conveying device 2, and the driving disk 4 rotates circumferentially and is adapted to drive the tape 5 to move horizontally; When the tape 5 moves horizontally, one side passes through the patch device 3, and the patch device 3 is adapted to flatten the edge of the tape 5; When the tail of the tape 5 is separated from the patch device 3, the patch device 3 is adapted to attach the protection piece 34 to the side wall of the tail of the tape 5, so that when the tape 5 is wound up, the protection piece 34 makes the tail of the tape 5 closely fit with the adjacent layer of the wound tape.
