[0038] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The illustrative embodiments and descriptions are only used to explain the present invention and are not intended to limit the present invention. Example

[0039] Please see Figures 1 to 4 This embodiment provides an automatic physical adhesive bonding device, comprising: a machine base 1 serving as the carrier of the entire device; a machine cover 12, which is disposed on the machine base 1 to form a working space, the working space being semi-enclosed to reduce dust entry and maintain the cleanliness of the working area; a conveying assembly 2 for transferring electronic products between various workstations; a dust removal assembly 9 for cleaning dust from the bonding surface of the electronic products supplied by the conveying assembly 2; a bonding assembly for bonding the film material to the bonding surface of the electronic products cleaned by the dust removal assembly 9, while separating individual film materials for precise bonding; and a feeding assembly for transferring the electronic products with the bonded film material from the conveying assembly 2 to the next process.

[0040] The film application assembly includes a multi-axis robot 11 mounted on the machine base 1, a film transfer suction cup assembly 4 mounted on the multi-axis robot 11, and a feeder 8 mounted on the machine base 1 for film supply. The feeder 8 enables precise feeding of individual film materials, and the film transfer suction cup assembly 4 has a rolling function to improve the film application quality. The multi-axis robot 11 has higher flexibility, facilitating film picking and application.

[0041] The tiltable suction cup plate 42 facilitates the picking up of film material during film removal and ensures the film material is tilted during application. Combined with the pressure roller assembly 44, this allows the film material to gradually adhere to the surface of the electronic product, preventing air bubbles. The dust removal assembly 9 ensures the cleanliness of the film application surface, improving the application quality. The conveying assembly 2, dust removal assembly 9, film application assembly, and unloading assembly enable fully automated, dust-free film application with high efficiency and quality.

[0042] Please see Figure 8 The film transfer suction cup assembly 4 includes a connecting base 40, a rolling lifting mechanism 43 disposed on one side of the connecting base 40, a pressure roller assembly 44 disposed on the rolling lifting mechanism 43, a suction cup plate 42 hinged to the bottom of the connecting base 40, and a suction cup tilting assembly 41 disposed on the connecting base 40 for driving the suction cup plate 42 to rotate at a corresponding angle. When the film is being applied, the suction cup plate 42 is tilted with one end facing the pressure roller assembly 44 lower than the other end. The friction between the suction cup plate 42 and the film material is less than the adhesion force between the film material and the electronic product. The air channels within the suction cup plate are segmented along the film application direction, ensuring that the film material remains tightly attached to the suction cup plate 42 during removal, guaranteeing the flatness of the film material and avoiding any impact on the film application process.

[0043] Please see Figure 9 The roller lifting mechanism 43 is a linear module. The pressure roller assembly 44 includes a pressure roller lifting slide rail 440, a pressure roller seat 441 that slides up and down along the pressure roller lifting slide rail 440, and a pressure roller body 442 disposed at the bottom of the pressure roller seat 441. The top of the pressure roller body 442 is elastically connected to the top of the pressure roller lifting slide rail 440 to prevent damage to electronic products and ensure appropriate pressure during film application. The surface of the pressure roller body 442 is elastic to ensure the uniformity of film application pressure and improve the film application quality. The suction cup plate 42 has a guide arc surface 443 at one end facing the pressure roller body 442 to guide the pressure roller body 442. In the initial film application position, the film material at the front edge of the suction cup plate 42 can be tightly attached to the product without ensuring that the film material must protrude from the front end of the suction cup plate 42, ensuring the film application quality at the initial position. At the same time, during the entire film application process, a small distance is maintained between the pressure roller body 442 and the suction cup plate 42, improving the film application quality.

[0044] Please see Figure 4 , Figure 6 and Figure 7 The dust removal assembly 9 includes a dust removal column 90 mounted on the machine base 1, a dust removal top plate 91 mounted on the dust removal column 90, and a dust removal vertical plate 92 mounted on the dust removal top plate 91. The dust removal vertical plate 92 is equipped with a tape assembly 93. The tape assembly 93 includes an unwinding assembly 930, a dust removal assembly 933, a tension assembly 931, a winding assembly 934, and a dust removal tape 932, sequentially mounted on the front side of the dust removal vertical plate 92. The dust removal tape 932 is sequentially connected to the unwinding assembly 930, the dust removal assembly 933, the tension assembly 931, and the winding assembly 934. The dust removal assembly 933 includes components that move up and down along the dust removal vertical plate 92. The system includes a sliding dust removal slide 9332, a dust removal rubber roller 9334 mounted on the dust removal slide 9332, a pressure-adhesive slide 9330 that slides up and down along the dust removal vertical plate 92, and a pressure-adhesive roller 9333 mounted on the pressure-adhesive slide 9330. Two pressure-adhesive rollers 9333 are provided and respectively attached to the upper sides of the dust removal rubber roller 9334. An elastic element 9331 connects the pressure-adhesive slide 9330 and the dust removal slide 9332. The elastic element 9331 is a tension spring mounted on both sides of the pressure-adhesive slide 9330 to ensure a balanced traction force on the pressure-adhesive slide 9330, thereby ensuring that the pressure-adhesive roller 9333 is attached to the dust removal rubber roller 9334. The elastic element 9331 is used to keep the dust removal roller 9334 in contact with the pressure roller 9333. Both the unwinding assembly 930 and the rewinding assembly 934 are powered to prevent uneven tension on the dust removal tape 932 and to prevent breakage of the dust removal tape 932. The tension assembly 931 is used to control the tension of the dust removal tape 932. Sensors for detecting the presence or absence of the dust removal tape 932 are installed along the path of the dust removal tape 932.

[0045] Please see Figure 6 and Figure 7 The dust removal upright plate 92 is equipped with a dust removal electric cylinder 939, which is connected to the dust removal slide block 9332 via a pressure sensor 936 to prevent the dust removal roller 9334 from applying excessive pressure to electronic products, ensuring dust removal quality while preventing damage to the electronic products. The tension assembly 931 includes a tension roller 9312, a tension seat 9310 that slides up and down along the dust removal upright plate 92, and a tension auxiliary roller 9311 disposed on the tension seat 9310. The dust removal tape 932 is sandwiched between the tension roller 9312 and the tension auxiliary roller 9311. A tension controller 935 is connected to the tension roller 9312. The tension seat 9310 is elastically connected to the dust removal upright plate 92, and the elastic force points towards the tension roller 9312.

[0046] Please see Figure 5The dust removal top plate 91 is equipped with a dust removal translation component 94, which is a linear module. The dust removal vertical plate 92 is disposed on the dust removal translation component 94. The conveying component 2 includes at least two parallel conveying lines. The conveying lines are equipped with carriers 3 for placing electronic products. The conveying lines are linear modules, which can accurately control the transfer of electronic products to a suitable position. The dust removal translation component 94 is used to switch the dust removal rubber roller 9334 between the two conveying lines to improve work efficiency.

[0047] Please see Figure 2 and Figure 11 The unloading assembly includes an unloading robot 10 mounted on the machine base 1, unloading grippers 5 mounted on the unloading robot 10, and a flipping assembly 6 mounted on the machine base 1. The flipping assembly 6 flips and positions the film-coated electronic product, facilitating precise gripping and unloading by the unloading robot 10. The flipping assembly 6 includes a positioning seat 63 mounted on the machine base 1, a flipping translation assembly 60 mounted on the machine base 1, a flipping lifting assembly 61 mounted on the flipping translation assembly 60, and a rotating assembly 62 mounted on the flipping lifting assembly 61. The rotating assembly 62 is equipped with flipping grippers 621 for holding the electronic product.

[0048] Please see Figure 2 and Figure 10 The positioning base 63 has a positioning strip 64 slidably and elastically connected around its top perimeter. The positioning strip 64 and the top of the positioning base 63 form a positioning cavity 68. The positioning strip 64 is equipped with a positioning guide roller 65. A positioning pressure sensor 67 is located at the center of the bottom of the positioning cavity 68. The top of the positioning base 63 has at least three non-collinear floating support elastic elements 66. The supporting force of the floating support elastic elements 66 on the electronic product is less than the weight of the electronic product. The balanced floating support elastic elements 66 facilitate the downward pressure of the electronic product into the positioning cavity 68, and facilitate the positioning pressure sensor 67 to detect whether the electronic product is positioned correctly.

[0049] Please see Figure 11 The rotating assembly 62 is equipped with a forward-extending flipping suction cup 620, which extends below the flipping gripper 621. Both the flipping translation assembly 60 and the flipping lifting assembly 61 are linear modules. To improve work efficiency, the rotating assembly 62 uses a rotary cylinder. The flipping gripper 621 has an L-shaped cross-section, meaning one side faces the flipping suction cup 620, preventing electronic products from falling and being damaged while maintaining a relatively small clamping force.

[0050] Please see Figure 3The unloading gripper 5 includes a quick-change connecting seat 50 and a gripping suction cup 51 disposed below the quick-change connecting seat 50. Anti-fall grippers 52 are provided around the gripping suction cup 51. When opened, the anti-fall grippers 52 are higher than the bottom of the gripping suction cup 51 to prevent interference with other components when gripping products from the positioning cavity 68. The anti-fall gripper 52 includes a vertically arranged gripping cylinder 520 and a gripper body 523 with one end hinged to the side of the gripping suction cup 51. The gripper body 523 has an arc-shaped sliding groove 522, and the cylinder rod of the gripping cylinder 520 has a sliding pin 521 that mates with the arc-shaped sliding groove 522. The structure is simple and small in size, easy to install, and operates quickly.

[0051] As a further improvement to this design, the housing 12 is provided with a cavity filter 13. The cavity filter 13 is used to blow air that meets the cleanliness requirements into the housing 12 or to circulate and filter the air in the housing 12 to ensure the cleanliness of the air inside the housing 12.

[0052] Please see Figure 1 To further ensure the quality of film application, a camera detection device 7 is installed on the machine 1. The camera detection device 7 takes pictures of the film-applied surface of the electronic product after dust removal and film application to detect the dust removal effect.

[0053] During operation, the electronic product to be coated is placed on the carrier 3, and the conveyor line moves the electronic product along with the carrier 3 to the dust removal station. The following processes are executed sequentially:

[0054] Dust removal process: The dust removal translation component 94 moves the dust removal roller 9334 to directly above the electronic product to be dusted. The dust removal electric cylinder 939 then drives the dust removal roller 9334 to move downward and adhere to the film surface of the electronic product. The carrier 3 continues to move backward, and the dust removal roller 9334 rolls over the entire film surface of the electronic product. The dust on the film surface of the electronic product is picked up by the dust removal roller 9334 and transferred to the dust removal tape 932.

[0055] Dust removal inspection process: Camera inspection device 7 takes pictures of the film-coated surface of the electronic product after dust removal. If dust is still present on the surface, the electronic product will undergo a dust removal process again.

[0056] Film application process: For electronic products that have passed the dust removal test, film application is performed. The feeder 8 supplies the rolled film to the film picking position. The multi-axis robot 11 moves the film transfer suction cup assembly 4 to the film picking position and picks up the corresponding film from the film picking position. At this time, the suction cup plate 42 is in a horizontal position under the control of the suction cup tilting assembly 41. The multi-axis robot 11 moves the suction cup plate 42 to the film application position. The suction cup plate 42 is in an inclined state under the control of the suction cup tilting assembly 41. The multi-axis robot 11 continues to drive the suction cup plate 42 to descend until the lowest side of the film is in contact with the film application surface of the electronic product. After that, the pressure roller assembly 44 descends and presses over the guide arc surface 443 and then presses on the film application surface of the electronic product. The multi-axis robot 11 moves horizontally, and the film is gradually pasted onto the film application surface of the electronic product under the traction of the adhesive force and the cooperation of the pressure roller body 442. However, if the film application surface is not flat, the multi-axis robot 11 can change the path in real time, and the suction cup plate 42 can also change the tilt angle to suit the film application requirements.

[0057] Film application inspection process: The inspection camera takes pictures of the film-applied surface of the electronic product after dust removal to check for defects such as bubbles. If there are no abnormalities in the film application, the electronic product with film applied is transferred to the unloading station.

[0058] The flipping and positioning process: The flipping translation component 60 moves the flipping gripper 621 to the unloading station. The flipping lifting component 61 drives the flipping gripper 621 to descend. The flipping suction cup 620 picks up the electronic product while the flipping gripper 621 holds the electronic product. The flipping lifting component 61 drives the flipping gripper 621 to rise. The rotating component 62 drives the flipping gripper 621 and the electronic product to flip 180°. The flipping translation component 60 moves the flipping gripper 621 to the positioning station. The flipping lifting component 61 drives the flipping gripper 621 to descend, and the electronic product is placed into the positioning cavity 68. During the process of placing the electronic product into the positioning cavity 68, the frame of the electronic product presses the positioning strip 64, causing the positioning strip 64 to move outward. During the pressing process, the positioning guide roller 65 is used to prevent damage to the electronic product. The positioning guide roller 65 is a rubber wheel.

[0059] Material unloading process: The gripping suction cup of the unloading claw 5 picks up the electronic product from the positioning seat 63. After the product is picked up, the anti-fall claw 52 closes and extends along the edge of the electronic product to the bottom of the electronic product.

[0060] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention.
