Description

Technical Field

[0001] This invention belongs to the field of semiconductor manufacturing technology, and in particular relates to a rubber bonding device. Background Technology

[0002] In semiconductor packaging, fragile substrates such as wafers are often secured to a support frame using rubber rolls (polymer films) to provide support for easy handling. To improve the stress resistance of the substrate edges and the reliability of the packaging, a layer of rubber roll is typically bonded to the side of the substrate. Existing bonding processes generally employ a pressing structure, where the rubber roll is pressed onto the side of the substrate using a device, allowing the rubber layer to adhere directly to the substrate surface for subsequent packaging and curing processes. However, this method suffers from low bonding accuracy, and impurities on the substrate sidewalls can easily cause localized bulging of the rubber layer, leading to easy delamination or edge lifting, affecting the flatness of the packaging and the yield of the finished product.

[0003] For example, Chinese invention patent with patent publication number CN110757597B and publication date of July 9, 2021 discloses an integrated plate edge banding device, the structure of which includes a base, a lifting mechanism, a rotating mechanism, a pressing mechanism, a positioning fixture, an edge banding and gluing mechanism, and a drying component.

[0004] The integrated edge banding device for sheet metal in this invention patent has the following general structural principle: The sheet metal is placed in the placement area formed by the positioning columns and rests on the top block of the support plate. Then, the lifting hydraulic cylinder slowly lifts the sheet metal and finally contacts the pressing plate. Under the action of the pressing spring, it is pressed and positioned, causing the cylinder to extend and the pressing wheel to contact the edge of the sheet metal. At this time, a section of edge banding strip is reserved on the pressing wheel. The cylinder continues to extend a short distance, and the push plate compresses the buffer spring, so that the pressing wheel is in close contact with the sheet metal and is in an elastic state. At this time, the drying component is in the non-working position, that is, away from the edge of the sheet metal. Then, the rotary motor is started to drive the sheet metal to rotate. At the same time, the glue injection machine injects glue into the glue application tube. The glue is applied first, and then the edge banding strip is pressed. After the sheet metal rotates one revolution, the edge banding process is completed. After completion, the glue application assembly retracts, and with the help of the connecting rod, it rotates and drives the air chamber to feed, eventually reaching the edge of the board. The excess edge banding is then manually cut off, and hot air is introduced into the air chamber through the air inlet pipe and blown onto the edge of the board to accelerate the glue drying process and improve production efficiency.

[0005] However, in actual use, this integrated edge banding equipment for sheet metal has at least two shortcomings, which are the technical problems that this invention aims to solve: 1. The edge banding strip needs to be cut manually, which is cumbersome, and the cut edge banding strip ends are prone to loosening and falling off, affecting the subsequent bonding efficiency; 2. The amount of glue dispensed from the glue applicator is difficult to control in real time, which causes local bulging or hollowing of the edge banding strip after bonding, affecting the flatness and adhesion of the seal.

[0006] Therefore, in summary, there is an urgent need for a new type of rubber bonding device that is highly efficient and has a high degree of flatness. Summary of the Invention

[0007] This invention provides a rubber bonding device that, by assembling an unwinding machine, a winding machine, a guide clamping assembly, a pressure roller, a through groove, and a bonding stop mechanism on a base, enables the following: 1. When the bonding stop mechanism acts on the rubber roll, it cuts the rubber roll and temporarily clamps and fixes the end, achieving automated cutting and improving the bonding efficiency for repeated use; 2. The bonding stop mechanism ensures that the adhesive coating on the board is of uniform thickness, and then the pressure roller presses the adhesive layer firmly onto the board, resulting in a stable, flat, and bubble-free bonding of the rubber roll, ensuring the flatness of the packaging and the yield of the finished product.

[0008] The technical solution adopted by the present invention to solve the above problems is: a rubber bonding device, comprising: a base; an unwinding machine and a winding machine disposed on both sides of the base; two guide clamping assemblies disposed on the base and moving closer to each other by lifting and clamping the upper and lower surfaces of the sheet material; a pressing roller shaft disposed on the base and extended by a cylinder to press and bond the adhesive layer of the rubber roll to the side surface of the sheet material; a through groove disposed on the base and close to the unwinding machine; and a bonding stop mechanism disposed in the through groove; the bonding stop mechanism includes a rotary motor disposed on the base with its output shaft vertically extending into the through groove, and a rotary motor output shaft disposed on... The system includes an installation block, a glue-applying plate on the side wall of the installation block for applying adhesive to the side surface of the sheet material, a stop roller on the base located on one side of the through groove, and a blade on the glue-applying plate near the stop roller. The rubber roll extends from the unwinding machine into the through groove, with the back film adhering to the stop roller and guided between the two guide clamping assemblies. After clamping, it is retracted by the winding machine. When the blade faces the sheet material, it is used to smooth the adhesive. When the blade rotates to face the stop roller, it is used to cut the rubber roll. When the blade rotates to near the base surface, it is used to temporarily fix the end of the rubber roll.

[0009] A further preferred technical solution is that the blade block includes a blade face that is inclined from the back of the blade to the blade edge and is used to temporarily fix the end of the rubber roll, a scraping part that is disposed at the blade edge and is used to scrape the glue, and a cutting part that is located at the connection position of the blade face and the scraping part and whose rotation path is tangent to the outer wall of the stop roller.

[0010] A further preferred technical solution includes a protrusion disposed on the base and located on the inner wall of the through groove, wherein the blade rotates to approach the protrusion to clamp the rubber roll together.

[0011] A further preferred technical solution is that the protrusion is a fan-shaped column.

[0012] A further preferred technical solution is that the guide clamping assembly includes a mounting plate, a first roller and a second roller rotatably mounted on the mounting plate and close to each other, and a lifting motor that drives the mounting plate to rise and fall, thereby driving the first roller and the second roller to clamp the same end face of the plate.

[0013] A further preferred technical solution is that the guide clamping assembly further includes a movable slot disposed on the mounting plate and located between the first roller and the second roller, avoiding the pressure roller shaft.

[0014] A further preferred technical solution is that the guide clamping assembly further includes a vertical guide rail disposed on the base, and a vertical slider slidably disposed on the vertical guide rail and used for mounting the mounting plate.

[0015] A further preferred technical solution is that the bonding and stopping mechanism further includes a sensor disposed on the base for detecting the positioning status of the board material near the glue application plate.

[0016] A further preferred technical solution includes a displacement component for adjusting the distance between the base and the plate. The displacement component includes a base plate, a displacement guide rail disposed on the base plate and perpendicular to the direction of movement of the plate, a displacement slider slidably disposed on the displacement guide rail and fixed to the bottom of the base, and a displacement cylinder for driving the base to move along the displacement guide rail.

[0017] A further preferred technical solution includes a support roller shaft disposed on the base for guiding the back film to the winding machine.

[0018] The technical effects and advantages of this invention are as follows: 1. By rotating the motor, the distance between the glue-applying plate and the blade block and the board and the stop roller shaft is changed, thereby realizing multiple functions of applying glue, cutting glue, and clamping glue; 2. The blade block presses the cut rubber roll end against the outer surface of the base, thereby realizing temporary positioning and limiting of the end, avoiding the problem of repeated gripping of the cut end, simplifying the pasting action, and improving the efficiency of the next rubber bonding; 3. The blade block scrapes the glue applied by the glue-applying plate to the side of the board to prevent local bulging or hollowing when the rubber roll is bonded to the board, ensuring the flatness of the board edge sealing.

[0033] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0034] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc., mentioned or possibly mentioned in this specification are defined relative to the structure shown in the accompanying drawings. The terms "inner" and "outer" refer to the direction toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0035] In this embodiment, as shown in the appendix Figure 1-12As shown, the conveying direction of the sheet material b (the length direction of the sheet material b) is taken as the positive direction of the X-axis, the direction extending along the width of the sheet material b towards the base 1 is taken as the positive direction of the Y-axis, and the vertical upward direction of the sheet material b is taken as the positive direction of the Z-axis. The sheet material b is placed on the conveyor belt and fed from the unwinding machine 2 of the rubber bonding device to the winding machine 3. The rubber bonding device is located on the side end where the sheet material b needs to be bonded, and includes the base 1, the unwinding machine 2, the winding machine 3, two guide clamping assemblies 4, the pressure roller shaft 5, the through groove 6, and the bonding stop mechanism 7. The base 1 is the main mounting structure, the unwinding machine 2 and the winding machine 3 are located on both sides of the base 1, and the distance between the base 1 and the sheet material b is less than the distance between the unwinding machine 2 and the winding machine 3 and the sheet material b. Two guide clamping assemblies 4 are disposed on the base 1, located at the upper and lower ends of the sheet material b respectively, clamping the upper and lower end faces of the sheet material b by moving closer to each other. This not only ensures the stable transport of the sheet material b but also prevents the rubber roll a from tilting. The pressure roller shaft 5 is disposed on the base 1 and is driven by a cylinder to extend and retract towards / away from the sheet material b, thereby pressing the adhesive layer a1 of the rubber roll a onto the sheet material b. The through groove 6 is disposed on the side of the base 1, near the unwinding machine 2. The rubber roll a is placed on the unwinding machine 2, with its end extending into the through groove 6 and extending towards the front of the base 1 (the side near the sheet material b), and is guided between the two guide clamping assemblies 4. The pressure roller shaft 5 extends towards the side of the sheet material b, causing the adhesive layer a1 and the back film a2 of the rubber roll a to separate. The adhesive layer a1 adheres to the sheet material b, and the back film a2 is wound back by the winding machine 3. When the rubber roll a is bonded, it is kept at the same height as the plate b. The adhesive layer a1 faces the plate b, and the back film a2 faces the base 1. During the bonding process, the adhesive layer a1 only contacts the plate b, avoiding contact with other structures and thus affecting its own adhesion strength.

[0036] Furthermore, the bonding and stopping mechanism 7 is disposed within the through groove 6 and includes the rotary motor 71, the mounting block 72, the glue-applying plate 73, the stop roller 74, and the blade 75. The rotary motor 71 is mounted on the base 1, with its output shaft extending vertically into the through groove 6. The mounting block 72 is disposed at the output end of the rotary motor 71. The glue-applying plate 73 is disposed on the side wall of the mounting block 72 and has a glue storage tank in the middle, with a glue outlet communicating with the storage tank on the side facing the board b. The blade 75 is disposed on the side of the glue-applying plate 73 near the stop roller 74, and the other side is connected to the glue storage tank and the glue bucket via a glue pipe, thereby continuously supplying glue to the glue-applying plate 73. The stop roller 74 is rotatably disposed on the base 1 and near the through groove 6. The rotary motor 71 drives the mounting block 72 to rotate within the through groove 6, causing the glue brush 73 and the blade block 75 to swing, so as to move closer to or away from the plate b, or relatively away from or closer to the stop roller shaft 74.

[0037] Finally, the working principle of the rubber bonding device is as follows: When the sheet material b is transported to a position close to the bonding stop mechanism 7, the rotary motor 71 drives the mounting block 72 to rotate in the forward direction, causing the adhesive brush 73 to approach the sheet material b and apply adhesive, thereby enhancing the bonding stability between the sheet material b and the rubber roll a. At this time, the distance between the blade of the cutter block 75 and the sheet material b is controlled at the distance where adhesive needs to be applied, thereby controlling the thickness of the adhesive applied to the sheet material b, ensuring that the adhesive is uniform and without excess coating, and avoiding uneven adhesive thickness from affecting the bonding effect of the rubber roll a. (See attached diagram) Figure 9-10 As shown, the side of the sheet material b is then bonded. The sheet material b is transported between the two guide clamping assemblies 4 and held by them from above and below. The cylinder drives the pressure roller 5 to move closer to the sheet material b, so that the adhesive layer a1 is pressed onto the side of the sheet material b. The backing film a2 is retracted under the drive of the winding machine 3. When it is time to finish bonding the rubber roll a, the rotary motor 71 drives the mounting block 72 to rotate in the opposite direction, so that the glue brush 73 and the blade 75 move away from the sheet material b and move closer to the stop roller 74, as shown in the attached figure. Figure 11As shown, the rotation trajectory of the blade 75 is tangential to the outer periphery of the stop roller 74, thereby cutting the rubber roll a on the stop roller 74. During cutting, the blade 75 directly contacts the adhesive layer a1, and the rubber roll a is temporarily fixed to the blade 75. Continuing to rotate the mounting block 72 causes the end of the rubber roll a on the unwinding machine 2 to be clamped between the blade 75 and the base 1. This allows for temporary positioning and restriction of the end of the rubber roll a, eliminating the need for the operator to monitor the position of the cut rubber roll a. During the next bonding operation, driving the blade 75 causes the rubber roll a adhered to it to move, making it easy for the operator to locate the end of the rubber roll a and directly separate it from the blade 75. The bonding operation can then be repeated, resulting in simple operation and high efficiency. This embodiment utilizes the blade 75 to automatically cut the rubber roll a, resulting in neat ends and reducing the possibility of warped edges or uneven ends. The rotary motor 71 is controlled according to the bonding requirements of the board b, which can not only achieve full edge sealing of the board b, but also partial edge sealing of the board b. The rubber bonding device has high applicability in various scenarios.

[0038] As a further improvement of this embodiment, the blade block 75 includes a blade surface 751 that is inclined from the back of the blade to the cutting edge and is used to temporarily fix the end of the rubber roll a, a scraping part 752 that is disposed at the cutting edge and is used to scrape the glue, and a cutting part 753 that is located at the connection position of the blade surface 751 and the scraping part 752 and whose rotation path is tangent to the outer wall of the stop roller shaft 74.

[0039] Specifically, the cutting edge length of the blade 75 is greater than the thickness of the sheet material b and the width of the rubber roll a. (See attached diagram) Figure 12 As shown, the blade face 751 near the stop roller shaft 74 is used to temporarily press the end of the rubber roll a against the surface of the base 1. The scraping part 752 is located at the blade edge, forming a space between it and the sheet material b for the passage of adhesive with a limited thickness, thereby ensuring that the adhesive thickness is uniform and flat. The cutting part 753 is the connecting area between the blade face 751 and the scraping part 752. When the blade block 75 rotates, the sharp edge of the cutting part 753 near the stop roller shaft 74 is tangential to the outer wall of the stop roller shaft 74, cutting the rubber roll a on the stop roller shaft 74. By rotating the blade block 75, different parts of the blade block 75 have different functions in different usage scenarios, so as to achieve the multiple effects of the bonding stop mechanism 7 in applying adhesive, cutting adhesive, and fixing adhesive. Preferably, the outer wall of the blade face 751 near the stop roller shaft 74 is provided with protrusions to separate the rubber roll a that is adhered to the blade face 751, thereby reducing the possibility of residual adhesive layer a1 adhering to the blade face 751.

[0040] As a further improvement to this embodiment, a protrusion 8 is also included, disposed on the base 1 and located on the inner wall of the through groove 6. The blade 75 rotates closer to the protrusion 8 to jointly clamp the rubber roll a. (See attached image) Figure 10-11 As shown, when the cutting part 753 cuts the rubber roll a, the protrusion 8 and the blade surface 751 come into contact with each other, thereby stably clamping the end of the rubber roll a. The protrusion 8 restricts the rotational freedom of the blade block 75 and is used to temporarily fix the end of the rubber roll a.

[0041] As a further improvement to this embodiment, the protrusion 8 is a fan-shaped column. The protrusion 8 protrudes to limit and block the blade block 75, while the rubber roll a passes between the protrusion 8 and the mounting block 72. To prevent the edge of the protrusion 8 from scraping against the rubber roll a, the contact surface of the protrusion 8 near the rubber roll a is rounded. Therefore, the protrusion 8 is a fan-shaped column, and the height of the protrusion 8 is greater than the width of the rubber roll a. When the blade block 75 rotates to the position of the protrusion 8, it is limited and blocked by it.

[0042] As a further improvement to this embodiment, the guide clamping assembly 4 includes a mounting plate 41, a first roller 42 and a second roller 43 rotatably mounted on the mounting plate 41 and close to each other, and a lifting motor 44 that drives the mounting plate 41 to rise and fall, thereby causing the first roller 42 and the second roller 43 to clamp the same end face of the plate b. Specifically, the first roller 42 and the second roller 43 protrude and are rotatably mounted on the mounting plate 41, located at the same height on the Z-axis, and spaced apart along the X-axis, with their central axis parallel to the Y-axis. The lifting motor 44 is a telescopic cylinder used to drive the mounting plate 41 to rise and fall, so that the first roller 42 and the second roller 43 together limit the same end face of the plate b.

[0043] As a further improvement to this embodiment, the guide clamping assembly 4 further includes a movable slot 45 disposed on the mounting plate 41 and located between the first roller 42 and the second roller 43, avoiding the pressure roller shaft 5. Specifically, when the plate b is clamped between the two guide clamping assemblies 4, it forms a space for the rubber roll a to pass through together with the base 1. Positioning the pressure roller shaft 5 between the first roller 42 and the second roller 43 increases the limitation on the rubber roll a, making it easier for the pressure roller shaft 5 to press the rubber roll a onto the plate b. The movable slot 45 is used to avoid the pressure roller shaft 5, so that the pressure roller shaft 5 can freely extend and retract, reducing mutual interference between structures.

[0044] As a further improvement to this embodiment, the guide clamping assembly 4 further includes a vertical guide rail 46 disposed on the base 1, and a vertical slider 47 slidably disposed on the vertical guide rail 46 for mounting the mounting horizontal plate 41. Specifically, the lifting motor 44 drives the mounting horizontal plate 41 to slide up and down along the vertical guide rail 46, thereby stabilizing the movement of the mounting horizontal plate 41. (See attached...) Figure 4-7 As shown, two sets of guide clamping assemblies 4 are arranged opposite each other on the base 1 along the Z-axis. Two lifting motors 44 drive two mounting horizontal plates 41 to move closer to each other / away from each other, thereby stably clamping the plates b of different thicknesses. Preferably, there are two vertical guide rails 46 and four vertical sliders 47, arranged in pairs opposite each other on the vertical guide rails 46. The vertical guide rails 46 extend along the Z-axis and are located at both ends of the mounting horizontal plates 41.

[0045] As a further improvement of this embodiment, the bonding and stopping mechanism 7 also includes a sensor 76 disposed on the base 1 for detecting the positioning state of the board b near the glue brush 73.

[0046] Specifically, the sensor 76 detects the position of the sheet material b. When the sheet material b is detected, it indicates a pre-lamination warning. The rotary motor 71 drives the glue-applying plate 73 and the blade 74 to rotate and move towards the side of the sheet material b, thereby applying and scraping glue. When the sensor does not detect the sheet material b, it indicates the end of the lamination process for that sheet material b, and the glue-applying plate 73 finishes applying glue to the tail of the sheet material b. The rotary motor 71 then drives the glue-applying plate 73 and the blade 74 to rotate towards the stop roller 74. The blade 74 cuts the rubber roll a and presses the end to fix it. This improves the accuracy of cutting the rubber roll a and reduces the possibility of insufficient glue application to the sheet material b or the rubber roll a being too long or too short.

[0047] As a further improvement to this embodiment, the base 1 includes a vertical plate 11, a mounting plate 12 disposed at the lower end of the vertical plate 11, and a reinforcing plate 13 disposed on the back of the vertical plate 11. To facilitate disassembly and maintenance of the contact stop mechanism 7, preferably, the base 1 also includes an ear plate 14 disposed on the vertical plate 11 and used to mount the contact stop mechanism 7. The ear plate 14 is a U-shaped plate with the through groove 6 in the middle. The stop roller shaft 74 and the mounting block 72 are disposed opposite each other on both sides of the ear plate 14. The rotary motor 71 is disposed on the ear plate 14, and its output shaft is vertically inserted into the through groove 6. Preferably, the base 1 further includes a mounting groove 15 disposed on the upright plate 11, for the guide clamping assembly 4 to move up and down, and for the pressure roller shaft 5 to extend and retract. The mounting horizontal plate 41 on the front of the upright plate 11 extends into the mounting groove 15 through an extension plate and is connected to the output end of the lifting motor 44 on the back of the upright plate 11, so that the extension plate can move within the mounting groove 15.

[0048] As a further improvement of this embodiment, the unwinding machine 2 includes a vertically arranged unwinding rod 21, a plurality of unwinding chucks 22 spaced on the unwinding rod 21 for placing the rubber roll a, and a spring pin 23 disposed on the unwinding rod 21 for fixing the unwinding chucks 22. The unwinding machine 2 can hold multiple rolls of rubber roll a at the same time. During normal operation, the uppermost roll of rubber roll a is used. To replace the rubber roll a, simply remove the rubber roll a from the upper unwinding chuck 22, move the lower unwinding chuck 22 and the rubber roll a to the upper layer and fix them by the spring pin 23.

[0049] As a further improvement to this embodiment, see the appendix. Figure 2 As shown, the winding machine 3 includes the winding mounting base 31, the winding motor 32 mounted on the winding mounting base 31, and the winding roller 33 mounted on the output shaft of the winding motor 32 and used to recycle the back film a2.

[0050] As a further improvement to this embodiment, see the appendix. Figure 3 As shown, the pressing roller shaft 5 includes a pressing shaft 51 disposed between the first roller 42 and the second roller 43 and slidingly rubbing against the rubber roll b; a pressing cylinder 52 disposed on the upright plate 11 and driving the pressing shaft 51 closer to or away from the plate b; a pressing mounting plate 53 disposed on the upright plate 11 and used to mount the pressing cylinder 52; and a pressing shaft insert 54 disposed at the output end of the pressing cylinder 52, passing through the mounting groove 15, and connected to the pressing shaft 51. The central axis of the pressing shaft 51 is parallel to the Z-axis and can rotate relative to the pressing shaft insert 54.

[0051] As a further improvement to this embodiment, see the appendix. Figure 1-3 As shown, the rubber bonding device further includes a displacement assembly 9 for adjusting the distance between the base 1 and the sheet material b. The displacement assembly 9 includes a base plate 91, a displacement guide rail 92 disposed on the base plate 91 and perpendicular to the moving direction of the sheet material b, a displacement slider 93 slidably disposed on the displacement guide rail 92 and fixed to the bottom of the base 1, and a displacement cylinder 94 for driving the base 1 to move along the displacement guide rail 92. Specifically, the base plate 91 is disposed below the base 1, the base 1 is slidably mounted on the displacement guide rail 92 via the displacement slider 93, and the displacement cylinder 94 drives the base 1 to move along the Y-axis, thereby adjusting the distance between the base 1 and the sheet material b to accommodate bonding requirements of sheet materials b with different widths.

[0052] As a further improvement to this embodiment, the rubber bonding device further includes a support roller 10 disposed on the base 1 for guiding the backing film to the winding machine 3. Specifically, the support roller 10 and the stop roller 74 are disposed opposite each other on both sides of the base 1 to guide the rubber roll a, preventing the rubber roll a from being deformed due to friction between the rubber roll a and the side of the upright plate 11, ensuring the stability of the shape of the rubber roll a and smooth transportation, and at the same time allowing the rubber roll a to approach the plate b in advance, reducing the pressing difficulty of the pressure roller 51.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the present invention.
