Description

Technical Field

[0001] This utility model relates to the field of circuit board manufacturing technology, specifically to an anti-deviation alignment structure for applying a cover film to a circuit board. Background Technology

[0002] Applying a cover film to a circuit board is an important step in the circuit board manufacturing process. The cover film is a protective film applied to the surface of the circuit board, usually made of special resin. It prevents the circuit board from being damaged by external environmental factors such as contamination (dust, dirt, etc.) and mechanical damage, ensuring the quality and performance of the circuit board. The cover film can connect the circuits, make the surface of the circuit board smoother, and enhance the flexibility and reliability of the circuit board.

[0003] Existing equipment has several drawbacks in its use. For example, in traditional lamination processes, circuit boards are often simply placed on a workbench, and the cover film is then applied manually or using simple mechanical devices. This method is not only inefficient but also makes it difficult to ensure a tight bond between the cover film and the circuit board, frequently resulting in problems such as bubbles and wrinkles, which seriously affect the quality and performance of the circuit board. Furthermore, during the transport of the cover film, due to the lack of effective limiting devices, the cover film is often prone to displacement due to external forces or equipment errors, leading to inaccurate lamination positions and requiring multiple alignments, which increases production and time costs. Utility Model Content

[0004] The purpose of this invention is to provide an anti-deviation alignment structure for applying cover film to circuit boards, which solves the problem that during the conveying process of cover film, due to the lack of an effective limiting device, the cover film is often prone to deviation due to external force or equipment error, resulting in inaccurate bonding position, requiring multiple alignments, and increasing production and time costs.

[0005] This utility model provides the following technical solution: an anti-deviation alignment structure for applying cover film to circuit boards, including a workbench, with support platforms symmetrically arranged on one side of the upper surface of the workbench, and leveling components arranged on the upper surface of the two support platforms, and an end anti-deviation component arranged on the other side of the workbench, with a middle anti-deviation component arranged between the leveling component and the end anti-deviation component, and the middle anti-deviation component arranged above the two support platforms.

[0006] As a preferred embodiment of the above technical solution, the leveling component includes fixed seats respectively fixedly installed on two support platforms, a lower leveling roller is provided between the two fixed seats, both ends of the lower leveling roller are rotatably connected to the fixed seats through bearings, an installation frame is also fixedly installed on the upper surface of the two support platforms, a cylinder is fixedly installed on the top wall of the two installation frames, the piston end of the two cylinders is vertically downward and the end is fixedly connected to a lifting plate, an upper leveling roller is provided between the two lifting plates, both ends of the upper leveling roller are rotatably connected to the side wall of the lifting plate through bearings.

[0010] As a preferred embodiment of the above technical solution, a caster wheel is fixedly installed on the lower end face of the workbench.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the circuit board is placed on a workbench, and then the cover film is flattened by a set flattening component.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Example

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: an anti-deviation alignment structure for applying cover film to circuit boards, including a workbench 1. A caster wheel 12 is fixedly installed on the lower end face of the workbench 1 to facilitate movement of the entire device. Support platforms 11 are symmetrically arranged on one side of the upper end face of the workbench 1. A leveling component 2 is arranged on the upper end face of the two support platforms 11. An end anti-deviation component 3 is arranged on the other side of the workbench 1. A middle anti-deviation component 4 is arranged between the leveling component 2 and the end anti-deviation component 3, positioned above the two support platforms 11. Specifically, it enables... During the process, the circuit board is placed on the workbench 1, and then the flattening component 2 is used to flatten the cover film, which ensures that the cover film and the circuit board are tightly bonded to a certain extent, without bubbles or wrinkles. The mid-stage anti-deviation component 4 performs a limiting operation in the middle stage of the cover film transportation process to prevent the cover film from shifting due to external force or equipment error. The end anti-deviation component 3 performs a final limiting operation when the cover film is transported to the end, ensuring that the cover film maintains the correct position before bonding is completed, thereby achieving precise alignment.

[0021] As one implementation method in this embodiment, such as Figure 1As shown, the leveling component 2 includes fixed seats 21 respectively fixedly installed on two support platforms 11. A lower leveling roller 22 is arranged between the two fixed seats 21. Both ends of the lower leveling roller 22 are rotatably connected to the fixed seats 21 via bearings. Mounting frames 23 are also fixedly installed on the upper surfaces of the two support platforms 11. Cylinders 24 are fixedly installed on the inner top walls of the two mounting frames 23. The piston ends of the two cylinders 24 are vertically downward and fixedly connected to lifting plates 25 at their ends. An upper leveling roller 26 is arranged between the two lifting plates 25. Both ends of the upper leveling roller 26 are connected to the side walls of the lifting plates 25. The bearings rotate to connect the components. In actual use, the cylinder 24 is activated, causing the lifting plate 25 to move the upper leveling roller 26 downward until it contacts the cover film. This method allows the upper leveling roller 26 and the lower leveling roller 22 to maintain an appropriate gap to accommodate the thickness of the cover film. Under the action of external force (such as manual or automatic pulling of the cover film), the cover film drives the upper leveling roller 26 and the lower leveling roller 22 to roll together. The upper leveling roller 26 and the lower leveling roller 22 continuously perform a leveling operation on the cover film until the cover film is completely adhered to the circuit board.

[0022] As one implementation method in this embodiment, such as Figure 1 and Figure 3 As shown, the end anti-deviation component 3 includes positioning plates 31 symmetrically fixedly installed on the workbench 1. Positioning grooves 32 are provided on the side walls of the two positioning plates 31. Two positioning rollers 33 are provided at both ends of the positioning grooves 32. The two positioning rollers 33 are symmetrically arranged vertically. In actual use, when the covering film is fed into the positioning grooves 32, it will be clamped and guided by the two positioning rollers 33. This clamping action ensures that the covering film always stays in the correct position during the movement, thereby avoiding the problem of deviation or misalignment. The rolling design of the positioning rollers 33 also reduces the friction and resistance of the covering film during the movement, making the whole process smoother and more efficient.

[0023] As one implementation method in this embodiment, such as Figure 2 As shown, the mid-end anti-deviation component 4 includes a fixed platform 41 fixedly installed on the upper surface of two support platforms 11. Guide rollers 42 are fixedly installed on the upper surface of the two fixed platforms 41. Anti-deviation columns 43 are fixedly connected to both sides of the two guide rollers 42. In actual use, during the movement of the cover film, the anti-deviation columns 43 prevent deviation and ensure that the material is always kept in the correct position. The cover film slides over the guide rollers 42, so that the cover film can enter the positioning groove 32 more smoothly.

[0024] As one implementation method in this embodiment, such as Figure 2As shown, guide rails 231 are fixedly installed on the inner sidewalls of both mounting frames 23, and guide blocks 232 are slidably connected to the guide rails 231. One end of the lifting plate 25 is fixed to the sidewall of the corresponding guide block 232. In actual use, the guide rails 231 are designed to provide a smooth and reliable sliding path for the guide blocks 232 so that the lifting plate 25 can move along this path.

[0025] Working principle: The cylinder 24 is activated, causing the lifting plate 25 to move the upper leveling roller 26 downwards until it contacts the cover film. This method maintains an appropriate gap between the upper and lower leveling rollers 22 to accommodate the thickness of the cover film. Under external force (such as manual or automatic pulling of the cover film), the cover film drives the upper and lower leveling rollers 26 and 22 to roll together. The upper and lower leveling rollers 26 and 22 continuously level the cover film. During the movement of the cover film, the anti-deviation column 43 prevents deviation. To ensure the material remains in the correct position, the cover film slides over the guide roller 42, allowing it to enter the positioning groove 32 more smoothly. As the cover film is fed into the positioning groove 32, it is clamped and guided by the upper and lower positioning rollers 33. This clamping action ensures that the cover film remains in the correct position during movement, thus avoiding offset or misalignment. The rolling design of the positioning rollers 33 also reduces friction and resistance during the movement of the cover film, making the whole process smoother and more efficient.

[0026] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
