Description

Technical Field

[0001] The utility model relates to the technical field of attaching devices, in particular to an automatic attaching device for a conductive adhesive film used for a circuit board. Background Art

[0002] Conductive adhesive is an adhesive with a certain conductivity after curing or drying. It can connect a variety of conductive materials together to form an electrical path between the connected materials. In the electronics industry, conductive adhesive has become an indispensable new material. There are many varieties of conductive adhesives. From the application perspective, conductive adhesives can be divided into general conductive adhesives and special conductive adhesives. General conductive adhesives only have certain requirements on the conductive properties and bonding strength of the conductive adhesive. In addition to certain requirements on the conductive properties and bonding strength, special conductive adhesives usually require the use of conductive adhesive films for bonding when installing circuit boards.

[0003] The existing film sleeve design is often complicated and difficult to disassemble and assemble. Once the film needs to be replaced, the operator usually needs to spend a lot of time and energy to remove the old film sleeve and install a new film sleeve, which not only affects the production efficiency, but may also cause equipment damage or reduced film attachment quality due to improper operation. At the same time, the existing pressure roller adjustment mechanism is usually cumbersome and has a limited adjustment range, making it difficult to adapt to circuit boards of different specifications and thicknesses. As a result, in the actual production process, the operator often needs to repeatedly adjust the pressure roller, or even replace the entire pressure roller device to adapt to different production needs.

The interior of the built-in frame 10 is clamped with a film sleeve 7, and limiting grooves 11 are provided on the opposite sides of the two mounting plates 9. Connecting plates 12 are provided on the opposite sides of the two side support plates 6. The limiting rods 13 are fixedly connected to the opposite sides of the two connecting plates 12. A reinforcing support plate 16 is fixedly connected to one side of the center of the front surface of the rear support plate 4. A movable plate 18 is provided below the front side of the rear support plate 4 corresponding to the reinforcing support plate 16. A micro cylinder 17 is fixedly installed on the top of the reinforcing support plate 16. The output end of the bottom of the micro cylinder 17 passes through the outer side of the reinforcing support plate 16 and is fixedly connected to the top of the movable plate 18. A pressure roller 20 is fixedly installed on the bottom of the movable plate 18.

[0017] The front and rear sides of the built-in frame 10 are both threadedly connected with fixing bolts 15, and the front and rear sides of the built-in frame 10 are both provided with fixing thread grooves 14 near the center. One side of the fixing bolts 15 penetrates to the outside of the fixing thread groove 14 and is threadedly connected to the film sleeve 7, ensuring that the film sleeve 7 is stably fixed in the built-in frame 10.

[0018] The side of the limiting rod 13 away from the connecting plate 12 penetrates into the limiting groove 11 and is engaged with the limiting groove 11 , thereby ensuring the stability and accuracy of the mounting plate 9 and the built-in frame 10 .

[0019] There is a certain distance between the side support plate 6 and the rear support plate 4.

[0020] The four sides of the top of the movable plate 18 are fixedly connected with damping support rods 19, and the top of the damping support rod 19 is fixedly connected to the bottom of the reinforcing support plate 16, thereby improving the stability of the pressing roller 20 during the attachment process.

[0022] The top of the mounting plate 9 penetrates into the interior of the mounting track 8 and is engaged with the mounting track 8 , so that the installation and removal of the mounting plate 9 become convenient and quick.

[0023] Working principle: The conveyor body 2 is started, and its conveyor belt drives the circuit board to pass through the top of the supporting base frame 3. After receiving the working signal, the micro cylinder 17 starts to work, and its output end pushes the movable plate 18 to move downward. The movable plate 18 is connected to the reinforcing support plate 16 through the damping support rod 19, which enhances its stability. As the movable plate 18 moves downward, the pressure roller 20 fixed at its bottom gradually approaches the circuit board. When the pressure roller 20 contacts the surface of the circuit board, the conductive film is pressed out of the film sleeve 7 with appropriate pressure through the precise control of the micro cylinder 17, and evenly attached to the surface of the circuit board. When the circuit board passes under the pressure roller 20, the micro cylinder 17 contracts, driving the movable plate 18 and the pressure roller 20 to rise, preparing for the next attachment. The conveyor body 2 continues to work, sending the attached circuit board out of the device, and at the same time sending the next circuit board to be attached into the device.

[0024] In summary: the automatic attaching device for the conductive adhesive film for the circuit board, through the design of the side support plate 6, the mounting rail 8, the mounting plate 9, the built-in frame 10, the limit groove 11, the connecting plate 12, the limit rod 13, the fixed thread groove 14 and the fixing bolt 15, utilizes the close combination of threaded connection and clamping to realize the stable fixation of the adhesive film sleeve 7 in the built-in frame 10. This design not only simplifies the disassembly and assembly process of the adhesive film sleeve 7, so that the operator can quickly complete the replacement of the adhesive film, thereby improving the production efficiency, but also effectively prevents the adhesive film from shaking or falling off during use, thereby improving the attachment quality. At the same time, a connection structure between the micro cylinder 17 and the movable plate 18 is adopted. Through the telescopic action of the micro cylinder 17, the movable plate 18 and the pressure roller 20 are flexibly adjusted. This design enables the height and position of the pressure roller 20 to be accurately adjusted according to circuit boards of different specifications and thicknesses, thereby ensuring that the adhesive film can be evenly and tightly attached to the circuit board, thereby improving the accuracy and consistency of attachment.
