Description

Technical Field

[0001] This invention relates to the field of automation technology, and more particularly to adhesive application equipment. Background Technology

[0002] In today's automated production processes, it's common to see tape applied to product surfaces. For example, before circuit boards enter the wave soldering oven, tape is manually applied to empty holes to prevent molten solder from overflowing onto the board's surface during wave soldering. In battery production, tape is applied to the surface of lithium batteries to prevent external dust and other impurities from entering the battery, ensuring cleanliness and performance. These tapes need to be removed later in the production process. Current technology typically uses adhesive machines to directly apply the tape to the desired locations. However, because the tape is directly attached to the product surface, the ends of the tape also adhere, making removal difficult and impacting production efficiency.

[0003] Furthermore, existing adhesive machines typically only allow adhesive to be applied to a single surface of a product. When multiple surfaces of a product need to be glued, such adhesive machines not only have low gluing efficiency but also tend to cause misalignment when gluing different surfaces, affecting product performance.

[0004] Therefore, an adhesive application device is needed to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an adhesive application device that can form regular adhesive tips at both ends of the adhesive tape and conveniently apply the tape to multiple surfaces of a product, thereby improving product adhesion efficiency and ensuring product performance.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0008] A folding assembly includes a flipping drive, a fixed plate, and two flipping plates. Along a first direction, the fixed plate is located between the two flipping plates. The flipping drive is configured to drive the flipping plates to rotate. Two grooves are spaced apart on the surface of the fixed plate, dividing the surface into a central adhesive surface and two side adhesive surfaces. Along the length of the fixed plate, the central adhesive surface is located between the two side adhesive surfaces. When the flipping plate rotates, it can cause the adhesive tape on it to adhere to one end of the adhesive tape on the side adhesive surfaces, forming an adhesive tip. The adhesive tape on the central adhesive surface is used to adhere to the first adhesive surface.

[0009] The adhesive roller assembly includes an adhesive roller drive and two adhesive rollers, the two adhesive rollers being respectively accommodated in two grooves. The adhesive roller drive is used to drive the two adhesive rollers to attach the adhesive tape on the two side adhesive surfaces to the two second adhesive surfaces one-to-one.

[0010] As an optional technical solution, both ends of the flip plate are provided with flanges along the second direction, which is perpendicular to the first direction.

[0011] As an optional technical solution, both the intermediate adhesive surface and the side adhesive surface are provided with adsorption holes.

[0012] As an optional technical solution, the roller assembly further includes a base, an elastic element, and two support frames. The two support frames are rotatably disposed on the base, and the base is installed at the output end of the roller drive. Each support frame is rotatably disposed with a roller wheel, and the elastic element is configured to drive the roller wheel to abut against the second adhesive surface.

[0013] As an optional technical solution, the adhesive applicator further includes a feeding component, a pulling component, and a cutting component. The feeding component is used to provide adhesive tape. The pulling component can pull out a preset length of adhesive tape from the feeding component and lay the tape on the fixed plate and the two flip plates. When the preset length of adhesive tape is laid on the fixed plate and the two flip plates, the cutting component can cut the tape.

[0014] As an optional technical solution, the feeding assembly includes a feeding roller, which is used to mount the tape roll.

[0015] As an optional technical solution, the material pulling assembly includes a pressing structure, a pulling structure, and a moving mechanism. The pressing structure can press against the tape led out from the discharging assembly, the pulling structure is used to clamp the tape, and the moving mechanism can drive the pulling structure away from the pressing structure by a preset length, thereby pulling out a preset length of tape.

[0016] As an optional technical solution, the pressing structure includes a pressing plate, a pressing block, a connecting block, and a pressing drive. One end of the connecting block is connected to the pressing plate, and the other end of the connecting block is rotatably connected to the pressing block via a rotating shaft. The output end of the drive is connected to the pressing block, and the pressing drive can drive the pressing block to rotate around the rotating shaft so that the pressing block abuts against the pressing plate.

[0017] As an optional technical solution, the adhesive applicator further includes a tensioning component, which is disposed between the feeding component and the pulling component. The tensioning component includes a plurality of tensioning rollers, and the adhesive tape is sequentially wound around the plurality of tensioning rollers.

[0018] As an optional technical solution, the tensioning assembly further includes an adjustment structure, which includes a guide rod, an adjustment block, a tension spring, and two positioning blocks. The two positioning blocks are spaced apart, the guide rod is disposed between the two positioning blocks, the adjustment block is adjustablely disposed on the guide rod, the tension spring is sleeved on the guide rod, and the tension spring is located between the adjustment block and one of the positioning blocks.

The first adhesive surface is located between the two second adhesive surfaces. The applicator includes a folding assembly and a roller assembly. The folding assembly includes a flipping drive, a fixed plate, and two flipping plates. The fixed plate is located between the two flipping plates. The flipping drive can drive the flipping plates to flip relative to the fixed plate. Two grooves are spaced apart on the surface of the fixed plate, dividing the plate surface into a middle adhesive surface and two side adhesive surfaces. When the flipping plates flip, they can drive the adhesive tape on them to adhere to one end of the adhesive tape on the middle adhesive surface to form an adhesive head. The adhesive tape on the middle adhesive surface is used to adhere to the first adhesive surface. The roller assembly includes a roller drive and two rollers. The roller drive is used to drive the two rollers to adhere the adhesive tape on the two side adhesive surfaces to the two second adhesive surfaces one by one.

The tape on the middle adhesive surface can be adhered to the first adhesive surface, and the tape on the two side adhesive surfaces can be correspondingly adhered to the two second adhesive surfaces by the rolling of the adhesive roller, improving the product bonding efficiency. The adhesive roller can also ensure the flatness and firmness of the adhesive, ensuring product performance. Attached Figure Description

[0041] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0042] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

[0045] like Figures 1 to 5As shown, this embodiment discloses an adhesive applicator for applying adhesive to a first adhesive surface and two second adhesive surfaces of a product. The first adhesive surface is located between the two second adhesive surfaces. The adhesive applicator includes a folding assembly 10 and a roller adhesive assembly 20. The folding assembly 10 includes a flipping drive 11, a fixed plate 12, and two flipping plates 13. Along a first direction, the fixed plate 12 is located between the two flipping plates 13. The flipping drive 11 is configured to drive the flipping plates 13 to rotate. Two grooves 121 are spaced apart on the surface of the fixed plate 12, dividing the surface of the fixed plate 12 into a central adhesive-bearing surface 122 and two side surfaces. The adhesive surface 123 is located along the length of the fixed plate 12, with the middle adhesive surface 122 situated between the two side adhesive surfaces 123. When the flip plate 13 rotates, it can drive the adhesive tape 2 on it to adhere to one end of the adhesive tape 2 on the side adhesive surface 123, forming an adhesive head. The adhesive tape 2 on the middle adhesive surface 122 is used to adhere to the first adhesive surface. The roller adhesive assembly 20 includes a roller adhesive drive 21 and two roller adhesive rollers 22. The two roller adhesive rollers 22 can be respectively accommodated in two grooves 121. The roller adhesive drive 21 is used to drive the two roller adhesive rollers 22 to adhere the adhesive tape 2 on the two side adhesive surfaces 123 to the two second adhesive surfaces one by one.

[0046] Specifically, in this embodiment, the adhesive backing of the tape 2 is supported on the fixing plate 12 and two flip plates 13 located on both sides of the fixing plate 12. The flipping drive causes the flip plates 13 to flip, so that the tape 2 on the flip plate 13 can adhere and bond with the tape 2 on the side adhesive surface 123, thereby forming an adhesive head, which facilitates the removal of the tape 2 from the product, thereby improving the tearing efficiency of the subsequent adhesive removal process; the fixing plate 12 is provided with two grooves 121, which are spaced apart, dividing the surface of the fixing plate 12 into a middle adhesive surface 122 and two side adhesive surfaces 123. 23. The tape 2 on the intermediate adhesive surface 122 is used to adhere the first adhesive surface of the product. The two rollers 22 of the roller assembly 20 are usually housed in two grooves 121 respectively. After the intermediate adhesive surface 122 and the first adhesive surface of the product are bonded together, the two rollers 22 extend out of the two grooves 121 under the drive of the roller drive component 21, thereby enabling the tape 2 on the side adhesive surface 123 to be bonded to the two second adhesive surfaces one by one, improving the product bonding efficiency. The setting of the rollers 22 is conducive to improving the flatness and firmness of the tape 2 bonding, thereby ensuring product quality.

[0047] In this embodiment, the first direction is the extension direction of the tape 2.

[0048] In this embodiment, the two side adhesive surfaces 123 have the same length, which is suitable for situations where the adhesive application lengths of the two second adhesive surfaces are the same. In another embodiment, the lengths of the two side adhesive surfaces 123 can also be set differently, which is suitable for situations where the adhesive application lengths of the two second adhesive surfaces are different, and will not be elaborated here. Furthermore, in this embodiment, the two second adhesive surfaces are parallel to each other, while in other embodiments, the two second adhesive surfaces are set at an angle.

[0049] In this embodiment, the roller drive component 21 is a roller cylinder.

[0050] In this embodiment, please refer to Figure 5 The folding assembly 10 and the roller adhesive assembly 20 are connected to the slide cylinder 80 and the side push cylinder 90. By adjusting the slide cylinder 80 and the side push cylinder 90, the positions of the folding assembly 10 and the roller adhesive assembly 20 can be adjusted to facilitate the application of the adhesive tape 2 to the product.

[0051] Furthermore, along the second direction, both ends of the flip plate 13 are provided with flanges 131, and the second direction is perpendicular to the first direction. Specifically, in this embodiment, the second direction is the width direction of the tape 2. Along the width direction of the tape 2, both ends of the two flip plates 13 are provided with flanges 131. This arrangement can limit the position of the tape 2, preventing the tape 2 from moving on the fixing plate 12 and the flip plate 13, thereby ensuring the regularity of the adhesive head and the flatness and positional accuracy of the tape 2 after it is pasted onto the product.

[0052] Optionally, each flip plate 13 is equipped with a flipping drive 11. Specifically, in this embodiment, this arrangement allows the two flip plates 13 to be controlled independently, facilitating the selective formation of one or two adhesive heads on the tape 2. This improves the versatility of the adhesive applicator, making it suitable for products with different adhesive application requirements and different numbers of adhesive heads.

[0053] Optionally, the flipping drive 11 is a flipping cylinder. Specifically, in this embodiment, the flipping assembly 10 also includes a mounting base, a fixing plate 12 is fixedly mounted on the mounting base, two flipping cylinders are mounted on the mounting base, and the output end of the flipping cylinder is connected to the flipping plate 13 for transmission. The flipping cylinder has a simple structure, is easy to use, and is stable to install.

[0054] Furthermore, adsorption holes 124 are provided on both the middle adhesive-carrying surface 122 and the two side adhesive-carrying surfaces 123. Specifically, in this embodiment, please refer to... Figure 3Adsorption holes 124 are provided on the middle adhesive surface 122 and the two side adhesive surfaces 123. The multiple adsorption holes 124 are evenly arranged and are connected to an external vacuum device. When there is tape 2 on the middle adhesive surface 122 and the two side adhesive surfaces 123, the external vacuum device draws negative pressure on the adsorption holes 124, so that the tape 2 can be tightly adsorbed on the middle adhesive surface 122 and the two side adhesive surfaces 123 under the action of air pressure. This can prevent the tape 2 from shifting position during the rotation of the folding plate, thereby ensuring the neatness of the tape head. At the same time, it can prevent the tape 2 from wrinkling or other defects on the product surface, which would affect the product quality.

[0055] In another embodiment, easy-tear adhesive can be applied to both the intermediate adhesive surface 122 and the two adhesive surfaces to fix the tape 2, which will not be described in detail here.

[0056] Further, please refer to Figure 4 The roller adhesive assembly 20 also includes a base 23, an elastic element 24, and two support frames 25. The two support frames 25 are rotatably mounted on the base 23, which is installed at the output end of the roller adhesive drive 21. Each support frame 25 has a roller adhesive wheel 22 rotatably mounted on it. The elastic element 24 is configured to drive the roller adhesive wheel 22 to abut against the second adhesive surface. Specifically, in this embodiment, the base 23 is installed at the output end of the roller adhesive drive 21, which can drive the base 23 to move, thereby allowing the roller adhesive wheel 22 located on the support frame 25 to move along the second adhesive surface. The support frame 25 is rotatably mounted on the base 23, and the elastic element 24 is a spring, which is disposed between the support frame 25 and the base 23 to ensure that the roller adhesive wheel 22 always abuts against the second adhesive surface, thereby ensuring the firmness of the adhesive tape 2. The roller 22 is rotatably mounted on the support frame 25, which can transform the static friction between the roller 22 and the second adhesive surface into rolling friction, improving the convenience of use and effectively reducing the wear of the roller 22.

[0057] In this embodiment, the roller drive component 21 is a roller cylinder.

[0058] Further, please refer to Figure 1The adhesive applicator also includes a feeding assembly, a pulling assembly 40, and a cutting assembly 50. The feeding assembly provides the adhesive tape 2. The pulling assembly 40 can pull the adhesive tape 2 of a preset length from the feeding assembly and lay the adhesive tape 2 on the fixed plate 12 and the two flip plates 13. When the adhesive tape 2 of the preset length is laid on the fixed plate 12 and the two flip plates 13, the cutting assembly 50 can cut the adhesive tape 2. Specifically, in this embodiment, the feeding component can provide tape 2, the pulling component 40 can pull tape 2 of a preset length from the feeding component and lay tape 2 on the fixing plate 12 and the flipping plate 13 of the flipping component, the cutting component 50 cuts the fixed tape 2, the flipping component can form adhesive heads at both ends of tape 2, and cooperate with the roller adhesive component 20 to stick tape 2 on the first adhesive surface and the second adhesive surface of the product. This adhesive application equipment has a high degree of automation and high adhesive efficiency. The setting of the roller adhesive wheel 22 makes the adhesive flat and firm, with high positional accuracy, and can form a regular adhesive head, which is convenient for tearing off tape 2 in subsequent processes, ensuring adhesive tearing efficiency.

[0059] Specifically, in this embodiment, please refer to Figure 8 The cutting assembly 50 includes a cutting cylinder 51 and a cutting knife 52. The cutting cylinder 51 drives the cutting knife 52 to move, thereby cutting the tape 2.

[0060] Furthermore, the feeding assembly includes a feeding roller 30, which is used to mount the tape roll 1. In this embodiment, the adhesive applicator also includes a mounting plate 70, on which the feeding roller 30 is rotatably mounted. The tape roll 1 is mounted on the feeding roller 30. When the pulling assembly 40 pulls the tape 2, the feeding roller 30 rotates relative to the mounting plate 70, thereby continuously supplying the tape 2 and ensuring adhesive applicator efficiency.

[0061] Further, please refer to Figure 2 , Figure 6 and Figure 7 The feeding assembly 40 includes a pressing structure 41, a feeding structure 42, and a moving mechanism 43. The pressing structure 41 can press against the tape 2 led out from the feeding assembly. The feeding structure 42 is used to clamp the tape 2. The moving mechanism 43 can drive the feeding structure 42 away from the pressing structure 41 by a preset length, thereby pulling the tape 2 of a preset length. Specifically, in this embodiment, the pressing structure 41 is fixedly set on the mounting plate 70 and is located downstream of the feeding roller 30. The feeding structure 42 is installed on the mounting plate 70 through the moving mechanism 43. In actual operation, the feeding structure 42 clamps one end of the tape 2, and the feeding structure 42 moves away from the preset distance under the drive of the moving mechanism 43. Then, the pressing structure 41 presses the other end of the tape 2, which facilitates the cutting structure to cut the tape 2.

[0062] Further, please refer to Figure 6The pressing structure 41 includes a pressing plate 411, a pressing block 412, a connecting block 413, and a pressing drive. One end of the connecting block 413 is connected to the pressing plate 411, and the other end of the connecting block 413 is rotatably connected to the pressing block 412 via a rotating shaft. The output end of the pressing drive is connected to the pressing block 412. The pressing drive can drive the pressing block 412 to rotate around the rotating shaft so that the pressing block 412 abuts against the pressing plate. Specifically, in this embodiment, the pressing drive is a pressing cylinder 414 with a horizontally arranged rotating shaft. One end of the pressing block 412 is connected to the pressing cylinder 414. When the pressing cylinder 414 extends, it drives the pressing block 412 to rotate relative to the rotating shaft, thereby causing the other end of the pressing block 412 to abut against the pressing plate 411 to press the tape 2 tightly. When the pressing cylinder 414 retracts, it drives the pressing block 412 to rotate in the opposite direction, thereby causing the other end of the pressing block 412 to separate from the pressing plate 411 and release the tape 2.

[0063] Specifically, in this embodiment, please refer to Figure 7 The material pulling structure 42 includes a gripper cylinder 421 and a gripper 422. The gripper cylinder 421 is used to drive the gripper 422 to open and close, so as to clamp and release the tape 2.

[0064] Specifically, in this embodiment, the moving mechanism 43 is a pen-shaped cylinder, the cylinder body of which is mounted on the mounting plate 70, and the telescopic rod of which is connected to the material pulling structure 42. In other embodiments, the moving mechanism 43 may also adopt, for example, a sliding rail and slider cooperation structure, which will not be described in detail here.

[0065] Further, please refer to Figure 1 , Figure 2 and Figure 9 The adhesive applicator also includes a tensioning assembly 60, which is positioned between the feeding assembly and the pulling assembly 40. The tensioning assembly 60 includes several tensioning rollers 61, around which the adhesive tape 2 is sequentially wound. Specifically, in this embodiment, the tensioning assembly 60 is positioned downstream of the feeding roller 30, and the adhesive tape 2 output from the feeding roller 30 is sequentially wound around the several tensioning rollers 61. This ensures that the adhesive tape 2 is tensioned between the tensioning rollers 61, guaranteeing the flatness of the adhesive tape 2 and ensuring the continuity of the adhesive tape 2 feeding.

[0066] Specifically, in this embodiment, four tension rollers 61 are provided, two of which are located on one side of the axis of the feed roller 30, and the other two are located on the other side of the axis of the feed roller 30. The tape 2 passes through the four tension rollers 61 in sequence and is then conveyed to the pressing structure 41. This ensures the flatness of the tape 2, prevents the tape 2 from becoming loose, and improves the adhesive bonding efficiency and effect.

[0067] Further, please refer to Figure 9The tensioning assembly 60 also includes an adjustment structure 62, which includes a guide rod 621, an adjustment block 622, a tension spring 623, and two positioning blocks 624. The two positioning blocks 624 are spaced apart. The guide rod 621 is positioned between the two positioning blocks 624. The adjustment block 622 is adjustablely positioned on the guide rod 621. The tension spring 623 is sleeved on the guide rod 621 and is located between the adjustment block 622 and one of the positioning blocks 624. A tension roller 61 is rotatably mounted on the adjustment block 622. Specifically, in this embodiment, after the tape 2 is conveyed from the feed roller 30, it passes through the tension rollers 61 in sequence, namely the first tension roller, the second tension roller, the third tension roller, and the fourth tension roller. The second tension roller is set on the adjusting block 622, which is adjustablely set on the guide rod 621. The tension spring 623 is set between the adjusting block 622 and the positioning block 624 near the first tension roller. This allows the second tension roller to adjust the tension of the tape 2 between the first tension roller and the third tension roller, improve the tension balance of the tape 2 at each tension roller 61, and thus avoid the tape 2 from being overstretched, ensuring the bonding effect of the tape 2.

[0068] The working process of the adhesive applicator is described in detail below. First, the tape roll 1 is installed on the feed roller 30, and the tape 2 is drawn, so that the tape 2 passes through the first tension roller, the second tension roller, the third tension roller, and the fourth tension roller in sequence. The pressure cylinder 414 is adjusted so that the pressure block 412 presses the tape 2 tightly onto the pressure plate 411. Then, the gripper cylinder 421 of the pulling structure 42 is adjusted so that the gripper 422 clamps the tape 2. Then, the pressure cylinder 414 is adjusted so that the pressure block 412 and the pressure plate 411 separate, releasing the tape 2. The moving mechanism 43 drives the pulling structure 42 to move a preset distance away from the pressure structure 41. Then, the pressure cylinder 414 is adjusted so that the pressure block 412 presses the tape 2 tightly onto the pressure plate 411. Finally, a vacuum is drawn into the adsorption hole 124 by an external vacuum device so that the tape 2 can be adsorbed onto the intermediate adhesive surface 122 and the pressure plate 411. On the two side adhesive surfaces 123; the adhesive cutting cylinder 51 drives the adhesive cutting knife 52 to cut the adhesive tape 2; adjust the flipping cylinder to flip the flipping plate 13, thereby adhering the adhesive tape 2 on the flipping plate 13 to the adhesive tape 2 on the side adhesive surfaces 123 to form an adhesive head; adjust the flipping cylinder to reset the flipping plate 13; then adjust the slide cylinder 80 and the side push cylinder 90 to move the folding assembly 10 and the roller adhesive assembly 20 to the product, and align the first adhesive surface of the product with the middle adhesive surface 122 of the fixing plate 12, so that the adhesive tape 2 on the middle adhesive surface 122 is pasted to the first adhesive surface; adjust the roller adhesive cylinder to make the two roller adhesive rollers 22 roll along the two second adhesive surfaces of the product respectively, thereby pasting the adhesive tape 2 on the two side adhesive surfaces 123 to the corresponding two second adhesive surfaces of the product, completing this adhesive operation.
