Description

Technical Field

[0001] The utility model relates to the field of metal processing and manufacturing, and particularly relates to a resin dust edge brushing device for a prepreg. Background Art

[0002] As an important base material, prepregs are widely used in fields such as electronics, construction, and packaging. During the production process of prepregs, it is necessary to cut the edges to obtain the required size and shape. However, edge cutting generates a large amount of resin dust and "caterpillar"-shaped waste edge materials. These dusts not only pollute the workshop environment but also adhere to the edges of the prepregs, affecting their appearance quality and even causing defects in subsequent processing, such as pits on the copper clad laminates during production. Therefore, effectively removing the resin dust on the edges of prepregs and properly handling the waste edge materials are crucial for ensuring product quality and production efficiency.

[0003] Currently, some technical solutions attempt to solve similar cleaning problems, such as cleaning resin residues and dust on semiconductor molds. Document 1 (Publication No.: CN216423168U) discloses a mold cleaning device with movable brushes. The device includes two fixed rail bodies, and guide bars are fixed at the top edges on the opposite sides. A cleaning device is arranged at the top near one edge of the two fixed rail bodies. Support frames are fixed at the bottom edges on the front and back sides of the cleaning device. Guide wheels are rotatably connected to the front surfaces of the two support frames near the two side edges through bearings, and all four guide wheels are correspondingly engaged with the two guide bars. A motor is fixed on the outer surface of one side of the cleaning device, and the motor drives the brushes to reciprocate on the slide rail, thereby increasing the cleaning intensity of the resin residues and dust on the mold.

[0004] However, when applying technical solutions similar to Document 1 to clean the edges of prepregs, the following significant defects exist:

[0005] Edge waste interference: The edge materials generated by cutting prepregs have irregular shapes. During the cleaning process, it is difficult for the brushes or other cleaning mechanisms in the existing technical solutions to avoid interference with these edge materials. This interference will cause the dust to not be effectively removed and may even raise the dust that has already fallen, resulting in secondary pollution.

[0006] In view of the characteristics of a large amount of dust generated by prepregs and strong adhesion, the cleaning efficiency of the existing technical solutions is difficult to meet the actual production requirements.

[0007] Therefore, there is an urgent need for a device that can efficiently remove the resin dust on the edges of prepregs, effectively handle the waste edge materials at the same time, and has a simple structure and is easy to operate. Summary of the Utility Model

[0008] In order to overcome the defects existing in the prior art, the utility model provides a semi-cured sheet resin dust edge brushing device, which can effectively solve the problem of waste material treatment.

[0009] The utility model solves the above technical problems through the following technical solutions:

[0010] A semi-cured sheet resin dust edge brushing device, which comprises: a bracket for installing on a semi-cured sheet trimming machine; a plurality of brush assemblies, each brush assembly including a brush and a frame structure for supporting the brush, the frame structure being connected to the bracket; wherein, the plurality of brush assemblies include at least two groups of brush assemblies arranged in parallel with a gap therebetween, the gap being for the semi-cured sheet to pass through and contact the brush assemblies. Such a design can effectively solve the problem of interference between waste materials and the cleaning mechanism in the prior art, thereby improving the cleaning efficiency.

[0011] Preferably, two groups of the brush assemblies are respectively provided on both sides of the bracket, and the brush assemblies on both sides are arranged in a relatively inclined manner. Thus, it can contact the edge of the semi-cured sheet from different angles, effectively improving the cleaning range and efficiency, and avoiding the limitation of single-direction cleaning.

[0012] Preferably, the brushing direction of the brush on the brush assembly on one side of the bracket is opposite to that of the brush on the brush assembly on the other side. Thus, an opposite brushing track is formed, enhancing the guiding effect on the dust, making the dust fall more concentratedly into the designated area, and further reducing the risk of secondary pollution.

[0013] Preferably, the brushing directions of the brushes of the two groups of brush assemblies on the same side of the bracket are the same. Thus, the "clamping" effect on the edge of the semi-cured sheet is strengthened, and the dust attached to the edge can be removed more thoroughly, avoiding dust residue.

[0014] Preferably, the brush assembly can be adjusted in position relative to the bracket. Thus, the adaptability of the device is enhanced, and it can be adjusted according to semi-cured sheets of different thicknesses and widths to ensure the best cleaning effect.

[0015] Preferably, the brush assembly can also be adjusted in angle relative to the bracket. Thus, the contact angle between the brush and the edge of the semi-cured sheet is further optimized, improving the cleaning efficiency and better adapting to the requirements of different production lines and processes.

[0016] In summary, through the setting of at least two groups of brush assemblies arranged in parallel with a gap therebetween and corresponding structural improvements, the utility model realizes the efficient removal of resin dust on the edge of the semi-cured sheet, while avoiding the interference of waste materials in the cleaning process, and solves the problems of low cleaning efficiency, easy interference of waste materials in cleaning, and poor adaptability of the device existing in the prior art. Brief Description of the Drawings

[0017] Figure 1 The structure diagram of the edge brush device for semi - cured sheet resin dust according to an embodiment of the present utility model. Detailed Embodiment

[0018] The embodiments of the present utility model will be described in detail below in conjunction with the drawings.

[0019] The present utility model provides an edge brush device for semi - cured sheet resin dust, which is mainly used to remove the edge resin dust generated during the cutting process of semi - cured sheets, and avoid the influence of dust on product quality and production environment. Figure 1 The structure diagram of the edge brush device for semi - cured sheet resin dust according to an embodiment of the present utility model. As Figure 1 shown, an edge brush device for semi - cured sheet resin dust provided by an embodiment of the present utility model includes a bracket 1, and the bracket 1 is used to be installed on a semi - cured sheet edging machine (not shown in the figure). A plurality of brush assemblies 2, the brush assembly 2 includes a brush 3 and a frame structure 4 for supporting the brush 3, and the frame structure 4 is connected to the bracket 1.

[0020] Among them, the plurality of brush assemblies 2 include at least two groups of brush assemblies 2 arranged in parallel with a gap therebetween, and the gap is used for the semi - cured sheet to pass through and contact the brush assembly 2. This structural design can effectively solve the problem of interference between the scrap and the cleaning mechanism in the prior art. Since there is a gap between the two groups of brush assemblies 2, when the semi - cured sheet passes through, the cut - off scrap can smoothly fall from the gap without colliding with the brush 3 or hindering the movement of the brush 3, thereby avoiding the influence of the scrap on the dust removal effect and improving the cleaning efficiency.

[0021] Preferably, as Figure 1 shown, two groups of the brush assemblies 2 are respectively arranged on both sides of the bracket 1, and the brush assemblies 2 on both sides are arranged in a relatively inclined manner. Specifically, the brush assemblies 2 on both sides are symmetrically distributed with the center line of the bracket 1 as the axis of symmetry, and the brush assemblies 2 on both sides form a certain angle α with the horizontal direction, for example, α is 15° - 45°. This inclined setting can achieve contact with the edge of the semi - cured sheet from different angles, effectively improving the cleaning range and cleaning efficiency. Compared with the traditional single - direction cleaning method, this multi - angle cleaning method can more thoroughly remove the resin dust attached to different positions on the edge of the semi - cured sheet, avoid cleaning dead corners, and further improve product quality.

[0022] Preferably, the direction of the brush 3 on the brush assembly 2 on one side of the bracket 1 is opposite to the direction of the brush 3 on the brush assembly 2 on the other side. For example, as Figure 1As shown, the brush 3 on the brush assembly 2 on the left side faces the upper left, while the brush 3 on the brush assembly 2 on the right side faces the upper right. This design of opposite brush orientations can form an opposing brushing trajectory, enhancing the guiding effect on the dust, making the dust fall more concentratedly into the designated area, preventing the dust from scattering everywhere, thereby further reducing the risk of secondary pollution and improving the environment of the production workshop.

[0023] Preferably, the brushes 3 of the two sets of brush assemblies 2 on the same side of the bracket 1 face the same direction. For example, as Figure 1 shown, the brushes 3 on the two sets of brush assemblies 2 on the left side of the bracket 1 both face the upper left, while the brushes 3 on the two sets of brush assemblies 2 on the right side of the bracket 1 both face the upper right. This design of the same brush orientation strengthens the "clamping" effect on the edges of the prepreg. When the prepreg passes through the two sets of brush assemblies 2, the brushes can clean the edges of the prepreg from the upper and lower directions, able to more thoroughly remove the dust adhering to the edges, avoid dust residue, and improve the cleanliness of the product.

[0024] Preferably, the brush assembly 2 can be adjusted in position relative to the bracket 1. For example, structures such as sliding rails and bolts can be used to achieve the sliding or movement of the brush assembly 2 on the bracket 1, thereby adjusting the relative position of the brush assembly 2 and the bracket 1. This position adjustment function enhances the adaptability of the device and can be adjusted according to prepregs of different thicknesses and widths. For example, for a thicker prepreg, the brush assembly 2 can be moved outward to ensure sufficient contact between the brush and the edge of the prepreg; for a thinner prepreg, the brush assembly 2 can be moved inward to avoid excessive cleaning and ensure the best cleaning effect.

[0025] Preferably, the brush assembly 2 can also be adjusted in angle relative to the bracket 1. For example, an adjustable connection mechanism such as a hinge or a bolt can be provided at the connection between the frame structure 4 and the bracket 1. By adjusting the connection mechanism, the inclination angle of the brush assembly 2 relative to the bracket 1 can be changed. This angle adjustment function further optimizes the contact angle between the brush and the edge of the prepreg. The inclination angle of the brush assembly 2 can be finely adjusted according to the shape of the edge of the prepreg and the adhesion of the dust, thereby improving the cleaning efficiency and better adapting to the requirements of different production lines and processes, enhancing the versatility of the device.

[0026] In summary, the present utility model realizes the efficient removal of resin dust on the edges of the prepreg by setting at least two sets of brush assemblies 2 that are parallel to each other and have a gap, as well as corresponding structural improvements. At the same time, it avoids the interference of the scraps on the cleaning process, and solves the problems of low cleaning efficiency, easy interference of the scraps on the cleaning, and poor adaptability of the device in the prior art.

[0027] It should be noted that the above embodiments are only for illustrating the technical solutions of the present invention, rather than limiting it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered within the scope of the claims of the present invention.
