Description

Technical Field

[0001] The present invention belongs to the field of conveying technology, and specifically relates to a device for transporting objects, and more particularly to a material belt conveying device and a conveying method for glass substrate packaging. Background Art

[0002] In the field of glass substrate packaging, tape conveyor equipment is the core equipment for realizing automated chip packaging. In existing technologies, the tape is usually designed to be reelable, and the unwinding reel and the take-up roller are used to achieve circular conveyance. However, there are the following technical bottlenecks:

[0003] Curvature accumulation and interlayer bonding defects. Traditional tapes are mostly made of hard polymer materials (such as PC and PET). Although they have a certain degree of toughness, repeated winding of the tape around the outer wall of the reel can significantly accumulate the curvature of the inner layers of the tape. When the tape is released from the reel, the innermost layer experiences the maximum bending deformation, causing its molecular chains to undergo irreversible orientation, resulting in a material memory effect. When rewinding, the innermost layer of the tape cannot fit tightly with the adjacent layers due to the mismatched curvature, forming a gap, causing the tape to loosen and even chip displacement.

[0004] In the prior art, manual attachment is usually used to attach the tail of the tape to the adjacent layer of the rewound tape. However, during manual attachment, the operator positions the tail of the tape based on experience, which can easily lead to misalignment due to hand shaking or visual deviation, causing gaps between layers or loose tape, exacerbating the curvature accumulation effect; moreover, direct contact between the tape and the chip area by human hands can easily introduce pollutants such as grease and dust, causing contamination of the glass substrate or chip surface, reducing the packaging yield.

[0005] Therefore, how to solve the problem of poor inter-layer bonding of material strips caused by the cumulative effect of curvature is a technical problem that urgently needs to be solved in this field.

[0006] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present application concept, and therefore, the above description is not considered to constitute information of related technology.

[0061] Research has found that in the field of glass substrate packaging, belt conveyor equipment is the core equipment for achieving automated chip packaging. In existing technologies, flexible belts are usually designed to be reelable, and circular conveying is achieved through the cooperation of a reel and a reel roller. However, there are the following technical bottlenecks:

[0062] Curvature accumulation and interlayer bonding defects. Traditional tapes are mostly made of hard polymer materials (such as PC and PET). Although they have a certain degree of toughness, repeated winding of the tape around the outer wall of the reel can significantly accumulate the curvature of the inner layers of the tape. When the tape is released from the reel, the innermost layer experiences the maximum bending deformation, causing its molecular chains to undergo irreversible orientation, resulting in a material memory effect. When rewinding, the innermost layer of the tape cannot fit tightly with the adjacent layers due to the mismatched curvature, forming a gap, causing the tape to loosen and even chip displacement.

[0063] In the existing technology, manual attachment is usually used to attach the tail of the tape to the adjacent layer of the rewound tape. However, during manual attachment, the operator positions the tail of the tape based on experience, which can easily lead to misalignment due to hand shaking or visual deviation, causing gaps between layers or loose tape, exacerbating the curvature accumulation effect; moreover, direct contact between the tape and the chip area by human hands can easily introduce pollutants such as grease and dust, causing contamination of the glass substrate or chip surface, reducing the packaging yield.

[0064] Therefore, how to solve the problem of poor interlayer bonding caused by curvature accumulation is a technical problem that needs to be solved urgently in this field.

[0065] The defects in the above solutions and the causes of their occurrence are the results obtained by the inventors after practice and careful research. Therefore, the process of discovering the above problems and the solutions proposed by the present disclosure in this article should be the contributions made by the inventors to the present disclosure during the disclosure process.

[0066] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0067] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0068] like Figures 1 to 7 As 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 provided 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 is provided on one side of the conveying device 2; the patch device 3 extends along the length of the conveying device 2 and is located above the material tape 5, and is used to flatten the passing material tape 5. A drive disk 4 is rotatably arranged at an end of the conveying device 2 away from the unwinding disk 1 and is located below the material tape 5; a drive motor is provided on one side of the conveying device 2, and the drive disk 4 is sleeved on the end of the rotating shaft of the drive motor, and the drive motor is used to drive the drive disk 4 to rotate. When the drive disc 4 rotates, it drives the strip 5 horizontally until the tail of the strip 5 detaches from the patch device 3. The patch device 3 is adapted to apply a protective sheet 34 to the sidewalls of the tail of the strip 5. This allows the protective sheet 34 to tightly fit the tail of the strip 5 and the adjacent layers of the wound strip 5 when the strip 5 is rewound. By positioning the patch device 3 on one side of the conveyor 2, when the tail of the strip 5 detaches from the linkage block 32, the linkage block 32 moves downward to apply the protective sheet 34 to the sidewalls of the tail of the strip 5. Furthermore, the provision of the protective sheet 34 ensures that the tail of the strip 5 tightly fits the adjacent layers when the strip 5 is rewound, thus preventing any gaps from forming between the tail of the strip 5 and the adjacent layers.

[0069] Reference Attachment Figure 3The 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 its length extends along the moving direction of the material belt 5. A linkage block 32 is arranged to be lifted and lowered on the positioning plate 31 near the material belt 5, and its bottom wall abuts against the material belt 5; a material tray 33 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 placed horizontally 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 drive disk 4 via the positioning plate 31, the vertical section 322 of the linkage block 32 abuts against the surface of the material belt 5, thereby achieving the effect of flattening the material belt 5. When the material strip 5 moves until its end disengages from the linkage block 32, the linkage block 32 moves downward, pulling the protective sheet 34 downward synchronously, placing the protective sheet 34 against the sidewall of the rear end of the material strip 5. After the protective sheet 34 is applied to the surface of the material strip 5, the material strip 5 continues to move toward the drive disk 4, and the heat-sealing roller 22 heat-seals the protective film to the surface of the material strip 5. At this point, the protective sheet 34 is located between the material strip 5 and the protective film. When the protective film needs to be removed, the protective film facilitates its removal from the material strip 5.

[0070] Continue to refer to the attached Figure 3 The linkage block 32 includes a horizontal section 321 and a vertical section 322. The vertical section 322 is perpendicular to the horizontal section 321. The bottom wall of the vertical section 322 abuts the material strip 5, and the bottom wall of one side of the horizontal section 321 abuts the protective sheet 34. The positioning plate 31 defines a receiving slot 310. The width of the receiving slot 310 is not less than the width of the horizontal section 321. A return spring 311 is disposed within the receiving slot 310. The lower end of the return spring 311 abuts the horizontal section 321. The return spring 311 is adapted to push the horizontal section 321 so that the vertical section 322 abuts the surface of the material strip 5.

[0071] Refer again to the attached Figure 3, the protective sheet 34 and the linkage block 32 are staggered, and the overlapping portion of the protective sheet 34 and the linkage block 32 is 1 / 5 of the total length of the protective sheet 34. When the material belt 5 moves horizontally toward the drive disk 4 through the linkage block 32, part of the protective sheet 34 is located on the material tray 33, and the other part of the protective sheet 34 is suspended above the material belt 5, and the overlapping portion of the surface of the protective sheet 34 and the linkage block 32 is in contact with the bottom wall of the horizontal section 321. When the material belt 5 moves to separate from the linkage block 32, the return spring 311 pushes the horizontal section 321 to move 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 equipment 2, the horizontal section 321 pushes the protective sheet 34 to move toward the direction of the material belt 5 until the protective sheet 34 is in contact with the surface of the material belt 5. The bottom surface of the protective sheet 34 is sticky and has a certain thickness and hardness as a whole, that is, Figure 6 After being adhered to the sidewall of the material strip 5, the protective sheet 34 remains parallel to the material strip 5, and its end away from the material strip 5 does not sag due to gravity. The protective sheet 34 is made of coated paper covered with a plastic film (PP / PET). The bottom surface of the protective sheet 34 is made of microsphere adhesive, which is composed of tiny spheres with controllable adhesion, allowing the adhesive to fall off completely when peeled off. The surface of the material tray 33 is smooth, and the protective sheet 34 (microsphere adhesive-coated paper) has a weak adhesion when adhered to the material tray 33.

[0072] The protective sheet 34 extends along the length 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 rewound, a pressure roller slides on the side wall of the reel. The pressure roller abuts the outer wall of the outermost layer of the rewound strip 5. When the protective sheet 34 at the end of the strip 5 moves to abut the pressure roller, the pressure roller squeezes the protective sheet 34, tightly adhering to the adjacent layer of the strip 5 inside, preventing the strip from loosening.

[0073] Reference Attachment Figure 4 A protective film roll 21 is rotatably mounted above the conveyor 2. The protective film extends from the protective film roll 21 to the surface of the laminating material strip 5. A heat sealing roller 22 is rotatably mounted above the conveyor 2. The heat sealing roller 22 is adapted to heat-seal the protective film to the surface of the material strip 5. The width of the heat sealing roller 22 is smaller than the width of the protective film.

[0074] Refer again to the attached Figure 4 The material strip 5 is evenly distributed with a plurality of positioning holes 50 along its length; the outer wall of the drive disc 4 is evenly distributed with a plurality of positioning posts 40 along its circumference, 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 material strip 5, the edge of the protective film is located above the positioning holes 50. The edge of the protective film near the positioning holes 50 is not heat sealed by the heat sealing roller 22. Figure 4The dotted line along the length of the hopper is the edge line of the heat seal of the protective film. The protective film located above the positioning hole 50 is not heat-sealed. A detection device 23 is provided above the conveying device 2. The detection device 23 is located above the drive disk 4. When the drive disk 4 drives the material belt 5 to move horizontally, the positioning post 40 is inserted into the positioning hole 50 and pushes the protective film located at the edge to tilt upward. If the upward tilt of the protective film edge is less than the normal range, the heat seal of the protective film edge is qualified. If the upward tilt of the protective film edge is greater than the normal range, the heat seal of the protective film is unqualified and there is a risk of inadequate heat sealing. The detection device 23 detects whether the heat seal of the protective film is qualified by detecting the tilting amplitude of the protective film.

[0075] Reference Attachment Figure 5 , the material belt 5 drives the disk 4 to move away from the unwinding disk 1, until the tail of the material belt 5 is separated from the unwinding disk 1, the tail of the material belt 5 passes through the positioning plate 31, and the tail of the material belt 5 is separated 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 sheet 34 to move downward synchronously, so that the protection sheet 34 is attached to the side edge of the tail of the material strip. Figure 5 F2 in FIG. 5 represents the moving direction of the material strip 5 .

[0076] Here’s how it works:

[0077] Reference Attachment Figure 3 When the material belt 5 moves horizontally along the conveying equipment 2, the vertical section 322 of the linkage block 32 abuts against the surface of the material belt 5. At this time, part of the protective sheet 34 is located on the material tray 33, and the other part of the protective sheet 34 is suspended above the material belt 5, and the upper surface of the protective sheet 34 abuts against the horizontal section 321.

[0078] Reference Attachment Figure 6 , the material strip 5 is transported to separate from the linkage block 32, the return spring 311 pushes the horizontal section 321 to move downward, and the horizontal section 321 pushes the protective sheet 34 to move downward synchronously. Since the protective sheet 34 partially overlaps with the linkage block 32, when the linkage block 32 moves downward to its maximum stroke, the protective sheet 34 can be attached to the surface edge of the material strip 5, and the final attachment effect is as follows Figure 7 As shown in the figure, one side of the protective sheet 34 is adhered to the edge of the material strip 5, and the other side is adhered to the surface of the material tray 33. At this time, the material tray 33 moves away from the material strip 5, so that the protective sheet 34 on the material tray 33 can be separated from the material tray 33. When the material tray 33 falls off, the linkage block 32 still presses on the protective sheet 34 until the material tray 33 and the protective sheet 34 are separated. At this time, the protective sheet 34 is adhered parallel to the edge of the material strip 5.

[0079] Figure 6F1 indicates the downward movement direction of the linkage block 32 pushed by the return spring 311 .

[0080] At least one embodiment provides a conveying method for a conveying device, the conveying method comprising:

[0081] The material belt 5 extends from the unwinding reel 1 to the conveying device 2, and the driving disk 4 rotates circumferentially to drive the material belt 5 to move horizontally;

[0082] When the material strip 5 moves horizontally, one side passes through the patch device 3, and the patch device 3 is suitable for flattening the edge of the material strip 5;

[0083] When the tail of the tape 5 is separated from the patch device 3, the patch device 3 is suitable for applying the protective sheet 34 to the side wall of the tail of the tape 5, so that when the tape 5 is wound, the protective sheet 34 makes the tail of the tape 5 fit tightly with the adjacent layer of the wound tape.
