Description

Technical Field

[0001] This utility model relates to the field of automatic adhesive application equipment technology, specifically to a large-size film automatic adhesive application machine. Background Technology

[0002] In the manufacturing process of electronic components, display panels, and FPC flexible circuit boards, it is often necessary to apply protective films, double-sided tape, or other functional adhesive films to their surfaces. Currently, automated adhesive application equipment on the market can only meet the adhesive application needs of small to medium-sized products (e.g., width less than 300mm). However, for large-sized products (e.g., 500mm × 380mm or larger), due to their large size, high positioning accuracy requirements, and the potential for air bubbles and wrinkles during the application process, existing automated equipment is insufficient.

[0003] Currently, the application of adhesives to large-sized products mainly relies on manual labor. Manual operation has many drawbacks: First, it is inefficient and cannot meet the needs of modern industrial mass production; second, the application accuracy and consistency are poor, the yield is low, and products are easily scrapped due to misalignment or air bubbles; finally, some adhesive films (such as 3M adhesive) have extremely high requirements for application pressure and uniformity, which are difficult to achieve manually.

[0004] Therefore, there is an urgent need in this field for a specialized device that can adapt to large-size products and achieve high-precision, high-efficiency, bubble-free automated film application. Utility Model Content

The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0021] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0023] like Figure 1-14 As shown, a large-size automatic film applicator includes a base 100. A feeding mechanism 1 is provided on one side of the base 100. The base 100 is equipped with a product conveyor belt 2, a film feeding mechanism 3, an applicator robot 4, and a receiving rack 5. The feeding mechanism 1 places the product to be processed onto the product conveyor belt 2. One end of the product conveyor belt 2 is connected to the feeding mechanism 1, and the other end is connected to the receiving rack 5. The product conveyor belt 2 transports the product to be processed to the applicator position of the applicator robot 4 and can deliver the applicated product to the receiving rack 5. A roller adsorption component 6 is installed on the output end of the applicator robot 4. The applicator robot 4 can drive the roller adsorption component 6 to connect to the film feeding mechanism 3 and the product conveyor belt 2 respectively, realizing the picking, placing, and applicating of film. The film feeding mechanism 3 is used to transport the film to be applicated.

[0024] During processing, the product to be processed is placed on the feeding mechanism 1, and the adhesive film to be applied is placed on the adhesive film feeding mechanism 3. The product is placed on the product conveyor belt 2 by the feeding mechanism 1, and the product is transported to the adhesive application position by the product conveyor belt 2. Then, the application robot 4 drives the roller adsorption component 6 to move to the adhesive film feeding mechanism 3, and the roller adsorption component 6 adsorbs the adhesive film. After that, the application robot 4 drives the roller adsorption component 6 to move the adhesive film above the product on the product conveyor belt 2, and then the roller adsorption component 6 rolls and applies the adhesive film to the product, completing the adhesive application. After that, the adhesive-applied product is transported to the receiving rack 5 by the product conveyor belt 2 for collection and unloading.

[0025] like Figure 2 , Figure 3As shown, to improve the accuracy of adhesive application, a film camera 200 and a product camera 300 are provided on the base 100. The product camera 300 is located above the product conveyor belt 2 and is used to capture images of the products on the product conveyor belt 2 to obtain the precise position and angle of the products. The mounting robot 4 can drive the roller adsorption assembly 6 to move the film above the film camera 200. The film camera 200 is used to capture images of the film on the roller adsorption assembly 6, thereby detecting the position and orientation of the film. After the product conveyor belt 2 transports the product to the adhesive application position, the product camera 300 will take a picture of the product to obtain image information of the product; before the mounting robot 4 drives the roller adsorption assembly 6 to move the film above the product, the mounting robot 4 will drive the roller adsorption assembly 6 to move the film above the film camera 200, and the film camera 200 will take a picture of the film to obtain position information such as the orientation angle of the film. Next, by comparing the image information of the film and the product, the deviation angle between the film and the preset adhesive application position on the product is calculated. Then, the corresponding deviation angle is compensated by the application robot 4. After adjustment, the film is rolled and adhered to the product by the roller adsorption component 6, completing the adhesive application process. This large-size automatic film adhesive application machine, through the cooperation of the film camera 200 and the product camera 300, combined with the application robot 4 for correction, can detect the position of the product and the film in real time, and perform precise alignment and angle correction to ensure accurate adhesive application position with an error of less than ±0.2mm, meeting the requirements of high-precision application.

[0026] To ensure the film camera 200 can capture clear images, a supplementary light 400 is installed on the base 100, positioned above the film camera 200. The supplementary light 400 illuminates the film on the roller adsorption assembly 6, enabling the film camera 200 to capture clear images. When the mounting robot 4 drives the roller adsorption assembly 6, carrying the film, to move above the film camera 200, the supplementary light 400 illuminates the film on the roller adsorption assembly 6, allowing the film camera 200 to capture clear images of the film. Simultaneously, a supplementary light (not shown) is also installed at the adhesive application position on the product conveyor belt 2. This supplementary light illuminates the products on the product conveyor belt 2, enabling the product camera 300 to capture clear product images.

[0027] like Figure 4As shown, the mounting robot 4 includes a mounting fixture 41, which is bolted to the base 100. A three-dimensional motion module 42 is mounted on the mounting fixture 41. The three-dimensional motion module 42 includes linear modules (such as lead screw modules, linear motor modules, etc.) for the X, Y, and Z axes, enabling precise positioning of the roller adsorption assembly 6 in three-dimensional space. A correction rotation module 43 (such as a servo motor-driven rotary platform) is mounted on the output end of the three-dimensional motion module 42. The roller adsorption assembly 6 is connected to the output end of the correction rotation module 43. The correction rotation module 43 drives the roller adsorption assembly 6 to rotate and performs angle correction based on the detection results of the film camera 200 and the product camera 300, ensuring accurate alignment of the film and the product.

[0028] like Figure 5-9 As shown, the roller adsorption assembly 6 includes a negative pressure adsorption assembly 61 and a roller adsorption assembly 62. The negative pressure adsorption assembly 61 includes a suction head mounting plate 611, a snap-fit ​​block 612, and an adsorption plate 613. The suction head mounting plate 611 serves as the main load-bearing structure, and a connecting seat 63 is fixedly mounted on its upper part. The connecting seat 63 is connected to the output end of the mounting robot 4. The lower end face of the suction head mounting plate 611 is machined with a dovetail groove 614. The left and right sides of the snap-fit ​​block 612 are formed with snap-fit ​​protrusions 615 that match the dovetail groove 614. The snap-fit ​​protrusions 615 and the dovetail groove 614 are detachably snapped together. The engagement of the snap-fit ​​protrusion 615 and the dovetail groove 614 secures the snap-fit ​​block 612 to the suction head mounting plate 611, thus connecting and fixing the negative pressure adsorption assembly 61 to the suction head mounting plate 611. By pulling the snap-fit ​​block 612, the snap-fit ​​protrusion 615 can be pulled out of the dovetail groove 614, thereby achieving the purpose of disassembling the negative pressure adsorption assembly 61. The adsorption plate 613 is sealed to the lower end face of the snap-fit ​​block 612.

[0029] The suction head mounting plate 611 is equipped with a negative pressure connecting pipe 64, and the adsorption plate 613 is evenly provided with multiple adsorption holes 616. The lower end face of the snap-fit ​​block 612 is provided with a hollow groove 617, and the snap-fit ​​block 612 is provided with a connecting hole 618. One end of the negative pressure connecting pipe 64 is connected to the connecting hole 618, and the other end is connected to a negative pressure device. The hollow groove 617 is connected to both the adsorption holes 616 and the connecting hole 618. By providing the hollow groove 617 and the connecting hole 618 on the snap-fit ​​block 612, each adsorption hole 616 on the adsorption plate 613 can be connected to the negative pressure connecting pipe 64, so that a uniform negative pressure suction can be generated on each adsorption hole 616, ensuring that the adsorption plate 613 can stably adsorb the film and improve the stability of the processing.

[0030] To improve sealing, a sealing ring 619 is provided on the upper surface of the snap-fit ​​block 612. The sealing ring 619 is fitted around the connecting hole 618 and makes a sealing contact with the suction head mounting plate 611. By setting the sealing ring 619, the snap-fit ​​block 612 and the suction head mounting plate 611 can be connected and sealed to prevent air leakage and ensure the stability of the processing of adhesive films and the application of adhesive.

[0031] like Figure 10 As shown, the roll-on assembly 62 includes a roll-on mounting base 621 fixedly mounted on the suction head mounting plate 611. Two symmetrically positioned lifting drive components 622 are mounted on the roll-on mounting base 621; in this embodiment, the lifting drive components 622 are cylinders. The output ends of the lifting drive components 622 are connected to a roller mounting frame 623. A freely rotatable roll-on roller 624 is mounted on the roller mounting frame 623 via bearings and a rotating shaft. During the roll-on process, the lifting drive components 622 drive the roller mounting frame 623 to lower the roll-on roller 624, causing it to contact the adhesive film. Then, the mounting robot 4 drives the roll-on adsorption device to move horizontally, causing the roll-on roller 624 to roll on the adhesive film surface, thus attaching the adhesive film to the product surface. After roll-on is completed, the lifting drive components 622 again drive the roller mounting frame 623 to raise the roll-on roller 624 back to its original position, causing it to detach from the adhesive film.

[0032] To ensure smooth lifting of the roller mounting frame 623, two roller lifting guide rods 625 are fixed on the roller mounting frame 623, and two roller lifting guide sleeves 626 are installed at corresponding positions on the roller mounting base 621. The roller lifting guide rods 625 pass through the corresponding roller lifting guide sleeves 626 and can slide up and down. The cooperation between the roller lifting guide rods 625 and the roller lifting guide sleeves 626 limits and guides the movement direction of the roller mounting frame 623, improving the accuracy of the transmission.

[0033] like Figure 11 As shown, the film feeding mechanism 3 includes a clamping and limiting seat 31 and a film feeding mechanism. The clamping and limiting seat 31 and the film feeding mechanism are bolted to the base 100. A film placement stage 32 is provided on the clamping and limiting seat 31, and the film placement stage 32 is slidably engaged with the clamping and limiting seat 31 via a guide rail. The film placement stage 32 is used to place the film to be mounted. The output end of the film feeding mechanism is connected to the film placement stage 32 and is used to drive the film placement stage 32 to slide on the clamping and limiting seat 31, thereby transporting the film placement stage 32 to the gripping position of the mounting robot 4.

[0034] Specifically, the film feeding mechanism includes a feeding motor 33, which is connected to the machine base 100. The machine base 100 has a rotatable feeding driven wheel 34, and the output end of the feeding motor 33 has a feeding drive wheel 35. A feeding drive belt 36 is fitted onto the feeding drive wheel 35 and the feeding driven wheel 34. The film placement table 32 is fixed to the feeding drive belt 36 by a connecting block. During processing, a person or a robot places the film to be mounted onto the film placement table 32. The feeding motor 33 drives the feeding drive wheel 35 to rotate, which in turn drives the film placement table 32 to move linearly via the feeding drive belt 36, thus achieving automatic feeding.

[0035] like Figure 12-13 As shown, the feeding mechanism 1 includes a feeding base 11, which is placed on one side of the machine base 100. The feeding base 11 is equipped with a feeding lifting mechanism 12 and a picking robot 13. The output end of the feeding lifting mechanism 12 is equipped with a discharge lifting plate 121, which is used to stack products to be processed. The feeding lifting mechanism 12 drives the discharge lifting plate 121 to move up and down. The picking robot 13 is used to grab products from the discharge lifting plate 121 and place them onto the product conveyor belt 2. During processing, the products to be processed are stacked on the discharge lifting plate 121, and the feeding lifting mechanism 12 drives the discharge lifting plate 121 to rise. When the topmost product on the discharge lifting plate 121 reaches the grabbing height of the picking robot 13, the picking robot 13 grabs the product from the discharge lifting plate 121 and transfers it onto the product conveyor belt 2, completing the automatic product feeding process.

[0036] To prevent products from sticking together during the feeding process, a first anti-sticking structure and a second anti-sticking structure are provided on the feeding base 11. The first anti-sticking structure can contact the side of the product on the unloading lifting plate 121, and directly acts on the side of the product at a physical level to separate products that may be slightly stuck together. The second anti-sticking structure is used to blow ion air towards the unloading lifting plate 121, eliminating static electricity on the product surface at the source and preventing electrostatic adsorption. This dual action of combining physical and static elimination can effectively solve the problem of electrostatic adhesion of large-sized sheet products, ensuring the single-sheet nature and stable reliability of the feeding process.

[0037] Specifically, the first anti-adhesion structure is an anti-adhesion brush 14 installed on the feeding base 11. The tips of the bristles of the anti-adhesion brush 14 lightly touch or come very close to the sides of the stacked products. When the products rise with the feeding lifting plate 121, the sides of the products rub against the anti-adhesion brush 14, and the bristles can separate the slightly stuck products. The second anti-adhesion structure is an ion air bar 15 installed on the feeding base 11. The ion air bar 15 can blow ion air towards the feeding lifting plate 121. The air outlet of the ion air bar 15 faces the product stack on the feeding lifting plate 121. After the ion air bar 15 is energized, it generates a large number of positive and negative ions. The resulting ion air blows towards the product surface, which can effectively neutralize the static electricity carried by the products due to friction and other reasons, and prevent the products from adsorbing and sticking together due to static electricity from the source.

[0038] A position sensor 16 (such as a photoelectric sensor) is installed on the feeding base 11 to detect whether the product at the top of the feeding lifting plate 121 has reached the preset gripping height and to send a signal to the control system. A material shortage sensor 17 is installed on the feeding lifting plate 121 to detect whether there are still products on the plate. When there is a material shortage, an alarm signal is issued to remind the operator to replenish the products in time.

[0039] like Figure 14 As shown, the material handling robot 13 includes a robot arm mounting frame 131, which is fixedly mounted on the loading base 11. A robot arm lateral movement module 132 (which can be a lead screw module or a synchronous belt module) is mounted on the robot arm mounting frame 131. A material handling mounting frame 133 is mounted on the output end of the robot arm lateral movement module 132. A material handling lifting cylinder 134 and a shaking cylinder 135 are mounted on the material handling mounting frame 133. Two first material handling suction cups 136 are mounted on the output end of the material handling lifting cylinder 134, and two second material handling suction cups 137 are mounted on the output end of the shaking cylinder 135. The first material handling suction cups 136 and the second material handling suction cups 137 are respectively connected to external negative pressure devices. When the robotic arm 13 is working, by applying negative pressure to the first and second suction cups 136 and 137, it can pick up the product at the top of the feeding lifting plate 121. Then, by driving the two second suction cups 137 to move back and forth through the vibration cylinder 135, the picked-up product is vibrated at a high frequency and with a small amplitude, ensuring that the robotic arm 13 only picks up a single product at a time, further reducing the risk of product sticking during feeding. After the first and second suction cups 136 and 137 have picked up the product, the robotic arm lateral movement module 132 and the lifting cylinder 134 work together to place the product onto the product conveyor belt 2, realizing the automatic feeding process.

[0040] Working principle: Before processing, the products to be processed are stacked on the feeding lifting plate 121, and the film is placed on the film placement table 32.

[0041] During operation, the loading lifting mechanism 12 drives the unloading lifting plate 121 to rise, bringing the top-level product to the picking position. The picking robot 13 picks up the product using the first picking suction cup 136 and the second picking suction cup 137, and places the product onto the product conveyor belt 2 through the cooperation of the robot lateral movement module 132 and the picking lifting cylinder 134. The product conveyor belt 2 then transports the product to the adhesive application station, where the product camera 300 captures an image of the product, obtaining its position and angle information. Simultaneously, the feeding motor 33 drives the film placement stage 32 to slide on the clamping limit seat 31, moving it to the gripping position of the mounting robot 4. The mounting robot 4 then drives the roller adsorption assembly 6 to the position of the film placement stage 32, where the negative pressure adsorption assembly 61 adsorbs the film. Finally, the mounting robot 4 moves the film above the film camera 200, where the film camera 200 captures an image of the film. Next, based on the product image and film image, the position and angle deviations are calculated, and the position and angle of the roller adsorption component 6 are adjusted by the correction rotation module 43. Subsequently, the roller adsorption component 6 moves above the product, and the lifting drive component 622 drives the roller roller 624 to descend, rolling it with a certain pressure to evenly attach the film to the product surface. After the adhesive is applied, the product conveyor belt 2 transfers the product to the receiving rack 5, completing the automatic receiving process.

[0042] This invention achieves high-precision and high-efficiency adhesive application for large-size products through fully automated design, effectively solving the problems of low efficiency, poor precision, and easy generation of bubbles and wrinkles in manual adhesive application, and significantly improving production yield and consistency.
