Description

Technical Field

[0001] This application belongs to the field of printed circuit board manufacturing technology, and in particular relates to an auxiliary tooling for grinding the edges of copper-clad laminates. Background Technology

[0002] Copper-clad laminate (CCL) is a sheet material made by impregnating electronic fiberglass cloth or other reinforcing materials with resin, covering one or both sides with copper foil, and then hot-pressing it. It is primarily used as a raw material for producing printed circuit boards (PCBs). During production, the CCL needs to be cut into rectangular pieces with two long edges that have burrs. These burrs require edge grinding. However, edge grinding is mainly done manually by pressing the CCL, which has relatively low stability and leads to inconsistent burr removal, affecting product quality. Utility Model Content

[0003] To address the shortcomings of the prior art, this application provides an auxiliary tooling for grinding copper-clad laminates, which can effectively fix the copper-clad laminates and improve the grinding quality.

[0004] To achieve the above objectives, the present invention employs the following technology:

[0005] An auxiliary tooling for grinding the edges of copper-clad laminates includes:

[0006] The substrate is set horizontally.

[0007] The support plate is horizontally mounted above the substrate and is used to place the copper-clad laminate.

[0008] The movable plate is horizontally positioned below the support plate, with vertically positioned limiting plates on both sides facing the length of the support plate. The two limiting plates are located on both sides of the support plate and are spaced a predetermined distance apart from the corresponding sides of the supporting plate. The top of each end of the limiting plate is connected to a diagonal bar facing the same direction. The diagonal bars on the two limiting plates face upwards towards the middle of the support plate, and the two diagonal bars on the limiting plates are located on the outer sides of both ends of the support plate. The movable plate is movable in the vertical direction.

[0009] Two pressure plates are connected at both ends to the ends of two diagonal bars facing the same direction. The projection of the pressure plates downward in the vertical direction is located on the bearing plate.

[0010] Furthermore, the pressure plate is set horizontally, with pressure rods slidably passing through both ends. A square frame is set horizontally above the pressure plate, and the upper ends of the four pressure rods are respectively connected to the four corners of the square frame. Springs are sleeved on the pressure rods and connected between the pressure plate and the square frame. When the pressure rods abut against the copper-clad laminate on the bearing plate, the top surface of the limiting plate is higher than the surface of the copper-clad laminate.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. When the linear mechanism drives the movable plate to rise to the top of the limiting plate, which is higher than the top of the bearing plate, the limiting plate can effectively limit the two sides of the copper-clad laminate, restricting its displacement along the width direction of the bearing plate. At the same time, it allows the two sides of the copper-clad laminate to extend equidistantly from the side of the bearing plate, ensuring that when the pressure plate presses and fixes the copper-clad laminate, both sides of the copper-clad laminate can be effectively exposed, so as to facilitate the grinding of its sides.

[0013] 2. The two pressure plates can apply pressure from multiple points along the length of the copper-clad laminate, which can make the copper-clad laminate more firmly fixed and relatively stable, so as to facilitate the edge grinding operation and improve the grinding quality.

Detailed Implementation

[0019] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0020] This application provides an auxiliary tooling for grinding the edges of copper-clad laminates, such as... Figures 1-4 As shown, it includes: substrate 1, support plate 2, movable plate 3, two pressure plates 4, etc.

[0021] Among them, such as Figures 1-4 As shown, the substrate 1 is horizontally arranged, and a pair of upright plates 13 are vertically arranged on it. The support plate 2 is horizontally mounted above the substrate 1 through the upright plates 13. The length of the support plate 2 is the same as the length of the copper clad laminate, and the width of the support plate 2 is smaller than the width of the copper clad laminate. Limiting blocks 21 are provided at both ends of the support plate 2.

[0022] like Figure 1 and Figure 2As shown, the movable plate 3 is horizontally positioned below the support plate 2 and oriented towards the length of the support plate 2. Vertical limiting plates 31 are arranged on both sides of the movable plate 3, oriented towards the length of the support plate 2. The two limiting plates 31 are located on opposite sides of the support plate 2 and are spaced a predetermined distance apart from each other. The distance between the two limiting plates 31 is equal to the width of the copper-clad laminate. The tops of both ends of the limiting plates 31 are connected to inclined rods 32 facing the same direction. The inclined rods 32 on the two limiting plates 31 face upwards towards the middle of the support plate 2, and are located on the outer sides of both ends of the support plate 2. A linear mechanism 11 is provided on the base plate 1, with its movable end vertically upwards and connected to the bottom surface of the movable plate 3. The linear mechanism 11 can be in the form of a linear cylinder, hydraulic cylinder, etc.

[0023] like Figure 1 and Figure 2 As shown, the two ends of the two pressure plates 4 are respectively connected to the ends of two inclined rods 32 facing the same direction. The pressure plates 4 are horizontally arranged and arranged along the length of the bearing plate 2. The projection of the pressure plates 4 downward in the vertical direction is located on the bearing plate 2.

[0024] When applying, such as Figure 1 and Figure 2 As shown, the linear mechanism 11 drives the movable plate 3 to move upward, so that the top surface of the limiting plate 31 is higher than the top surface of the bearing plate 2. The operator places the copper-clad laminate horizontally between the pressure plate 4 and the limiting plate 31 onto the bearing plate 2. The two sides of the copper-clad laminate abut against the opposite surfaces of the two limiting plates 31, so that the two sides of the copper-clad laminate extend equidistantly from both sides of the bearing plate 2. The two ends of the copper-clad laminate abut against the limiting blocks 21 to limit the displacement of the copper-clad laminate along the length direction of the bearing plate 2, while ensuring that the end face of the copper-clad laminate is coplanar with the end face of the bearing plate 2.

[0025] like Figure 1 and Figure 2 As shown, after the copper-clad laminate is placed on the carrier plate 2, the linear mechanism 11 drives the movable plate 3 to move down until the pressure plate 4 presses and fixes the copper-clad laminate on the carrier plate 2. At the same time, as the movable plate 3 moves down, the two sides of the copper-clad laminate will be exposed between the two limiting plates 31 and located between the two inclined rods 32. The limiting plates 31 move to the bottom of the two sides of the copper-clad laminate. At this time, the copper-clad laminate is pressed and fixed by the pressure plate 4, and the two sides of the copper-clad laminate are exposed. The two sides of the copper-clad laminate can be ground manually or automatically to remove burrs.

[0026] When the linear mechanism 11 drives the movable plate 3 to rise until the top surface of the limiting plate 31 is higher than the top surface of the bearing plate 2, the limiting plate 31 can effectively limit the two sides of the copper-clad laminate, restricting its displacement along the width direction of the bearing plate 2. At the same time, it allows the two sides of the copper-clad laminate to extend equidistantly from the sides of the bearing plate 2, ensuring that when the pressure plate 4 presses and fixes the copper-clad laminate, both sides of the copper-clad laminate can be effectively exposed, so as to facilitate the grinding of its sides. Meanwhile, when the linear mechanism 11 drives the movable plate 3 to move downward, the two pressure plates 4 can apply pressure from multiple points along the length direction of the copper-clad laminate, which can make the copper-clad laminate more firmly fixed and relatively stable, so as to facilitate the edge grinding operation and improve the grinding quality.

[0027] Specifically, before the pressure plate 4 moves down to press the copper-clad laminate, the limiting plate 31 will move down below the copper-clad laminate. During this time, there is no corresponding structure to limit the sides of the copper-clad laminate. The vibration generated by the movement of the movable plate 3 or other factors may cause the copper-clad laminate to shift along the width direction of the support plate 2, resulting in a change in the distance between the side of the copper-clad laminate and the side of the support plate 2. To solve the above problem, this embodiment proposes a preferred solution, as follows: Figures 1-4 As shown, pressure rods 41 are vertically and slidably inserted at both ends of the pressure plate 4. A square frame 42 is horizontally positioned above the pressure plate 4. The upper ends of the four pressure rods 41 are respectively connected to the four corners of the square frame 42. Springs 43 are sleeved on the pressure rods 41 and are connected between the pressure plate 4 and the square frame 42. When the pressure rods 41 abut against the copper-clad laminate on the support plate 2, the top surface of the limiting plate 31 is higher than the surface of the copper-clad laminate. That is, when the pressure rods 41 abut against the copper-clad laminate on the support plate 2, the limiting plate 31 can still limit the copper-clad laminate. As the movable plate 3 moves down, the springs 43 are stretched, and the elastic force of the springs 43 is converted into the pressure of the pressure rods 41 pressing down on the copper-clad laminate. Before the limiting plate 31 moves below the copper-clad laminate, the four pressure rods 41 fix the copper-clad laminate, which can effectively prevent the copper-clad laminate from moving along the width direction of the support plate 2 after the limiting plate 31 moves below the copper-clad laminate, thus improving the reliability of the tooling.

[0028] Specifically, such as Figure 1 and Figure 2 As shown, the square frame 42 has vertical rods 44 at both ends, and the top of the vertical rods 44 is connected by a horizontal rod 45. When installing the copper-clad laminate, the horizontal rod 45 can be pulled up to move the pressure rod 41 upward, so as to leave space for the installation of the copper-clad laminate.

[0029] Preferred, such as Figure 1 and Figure 2 As shown, both ends of the two limiting plates 31 are vertical and slidably connected to guide rods 12. The guide rods 12 are fixed on the base plate 1. Under the guidance of the guide rods 12, the stability of the lifting stroke of the movable plate 3 can be improved.

[0030] The above description is only a preferred embodiment of this application and is not intended to limit this application. Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application.
