Description

Technical Field

[0001] This invention relates to the field of integrated circuit manufacturing technology, and more specifically, to a copper-clad laminate laminating apparatus for printed circuit board manufacturing. Background Technology

[0002] In the integrated circuit manufacturing process, copper-clad laminate (CCL) lamination technology is a core step in ensuring the structural stability and electrical performance of the circuit board. It involves using a high-temperature, high-pressure process to tightly bond multiple layers of materials, such as fiberglass cloth and copper foil, with a resin adhesive to form a substrate with specific mechanical strength and insulation properties. However, the resin adhesive melts and flows during the heating and pressing process, easily overflowing from the edges and gaps of the multi-layered materials, forming irregular residual adhesive layers. If these residual adhesive layers are not cleaned in time, they will not only cause the edge flatness of the laminated CCL to exceed the standard, affecting the processing accuracy of subsequent cutting and drilling processes, but may also solidify and adhere to the surfaces of the equipment's pressing plates and clamping components, causing equipment malfunctions such as mold jamming and positioning deviations. The commonly used manual cleaning method in existing technologies not only faces the problem of low operational safety in high-temperature environments, but also the cleaning rhythm is difficult to match with the pace of automated lamination production lines. Delayed cleaning can easily lead to adhesive layer solidification, further increasing the cleaning difficulty. Furthermore, the subjectivity of manual operation can result in inconsistent cleaning effects, severely restricting production efficiency and product yield.

[0003] Traditional dedicated scraping equipment, while attempting to address the drawbacks of manual cleaning, is limited by its structural design. The scraping components and clamping mechanisms are relatively fixed in position, only suitable for single-size copper-clad laminate raw materials. This fails to meet the processing needs of diverse, small-batch production of different sizes of raw materials, resulting in extremely poor adaptability and versatility. More importantly, the adjustment mechanisms of these devices are mostly manual mechanical adjustments, cumbersome to operate, and with low adjustment precision. This makes it difficult to quickly respond to changes in production specifications, thus affecting the reliability of subsequent soldering and assembly processes on the circuit board, limiting their application in high-precision copper-clad laminate production. Therefore, in order to solve the above-mentioned technical problems, the present invention proposes a copper-clad laminate laminating device for printed circuit board manufacturing. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a copper-clad laminate laminating device for printed circuit board manufacturing.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a copper-clad laminate laminating device for printed circuit board manufacturing, comprising a machine body, a pressure plate disposed within the machine body, and clamping members disposed at each of the four corners of the pressure plate, wherein the clamping members are used to clamp the raw material, and the pressure plate is provided with an adjustment groove for the clamping members to move, the clamping members passing through the adjustment groove and disposed on a support base, the support base being connected to a synchronous drive mechanism, the synchronous drive mechanism being used to drive the multiple clamping members to move synchronously; The clamping member includes two first clamping blocks and two second clamping blocks. The two first clamping blocks are arranged diagonally, and the two second clamping blocks are arranged diagonally. Two sliding rods are provided on the first clamping blocks, and the two sliding rods are respectively arranged corresponding to the two second clamping blocks. A limiting block is provided on the second clamping block for the sliding rods to pass through. The slide bar has a cavity, and a lead screw is rotatably installed in the cavity. The scraping component is slidably installed in the cavity and threadedly connected to the lead screw. One end of the lead screw is connected to a driving component A. The scraping mechanism can follow the movement of the adjustment mechanism and adapt itself.

[0006] Furthermore, the scraping assembly includes a base threadedly connected to the lead screw, a receiving block is provided on the base, and a sliding cavity is provided in the base for the receiving block to slide. The receiving block and the base are connected by an elastic member. A first scraper is provided on the base, and a second scraper is provided on the receiving block. The first scraper and the second scraper are closely attached to each other and staggered. The second scraper and the first scraper are slidably arranged and can overlap. To facilitate complete clamping of multi-layered materials, the horizontal height of the clamping component and the receiving block is higher than that of the multi-layered materials. Furthermore, to accommodate materials of different sizes, the laminating plate of the stamping mechanism is designed with a larger dimension. Therefore, when laminating the materials, the laminating plate will first contact the clamping component. After being squeezed by the laminating plate, the clamping component compresses the elastic element B and moves it towards the support base, allowing the laminating plate to contact the materials for lamination. The second scraper also moves based on the first scraper, contracting under the pressure of the pressure plate until the laminating plate contacts the raw material surface. As the laminating plate compresses the multiple layers of raw material, the layers become compacted, reducing the thickness. During this process, the clamping component and the receiving block can adaptively adjust according to the compression of the laminating plate, thus adapting to the entire lamination process. Resin leaks from between the multiple layers of raw material during lamination. The second scraper, following the adaptive adjustment between the receiving block and the second scraper, can adapt to the thickness of the multiple layers of raw material for comprehensive scraping, improving scraping efficiency and enhancing the scraping effect. Furthermore, the clamping member and the support base are connected by an elastic member A, and the clamping member is provided with a guide rod, and the support base is provided with a groove for the guide rod to pass through.

[0007] Furthermore, the synchronous drive mechanism includes a drive component B, the drive end of which is provided with a bevel gear, and one end of the adjusting rod is provided with a transmission gear, which meshes with the bevel gear.

[0008] Furthermore, a flow channel is provided on the base corresponding to the position of the first scraper, and the flow channel is connected to the storage cavity inside the base.

[0009] Furthermore, the base is provided with a heating component for heating the storage cavity inside the base, the first scraper, and the second scraper.

[0010] Furthermore, the first scraper is pressed against the surface of the pressure plate.

[0011] Furthermore, the base is provided with multiple sets of the first scraper blades, which are arranged in a mirror image, and the receiving block is provided with multiple sets of the second scraper blades, which are arranged in a mirror image.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The synchronous drive mechanism moves four sets of clamping components synchronously along the adjustment groove, precisely adapting to the clamping requirements of copper-clad laminate raw materials of different specifications (from customized small sizes to standard large sizes). This allows for rapid switching of production specifications without the need to change to specialized equipment. Simultaneously, the scraping mechanism can move and adjust along with the clamping components, overcoming the limitation of traditional scraping equipment that can only adapt to a single size of raw material. This improves the versatility of the scraping equipment and broadens its application range. Attached Figure Description

[0019] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0020] like Figures 1-7 As shown, this invention provides a copper-clad laminate laminating device for printed circuit board manufacturing, including a body 1, which is a hollow rectangular shell structure. A pressure plate 2 is fixedly installed inside the body 1. The pressure plate 2 is used to support the raw material 16 to be processed. A stamping mechanism is also provided at the position corresponding to the pressure plate 2 for laminating the raw material 16. Each of the four corners of the pressure plate 2 has an elongated adjusting groove 8 extending along the length or width of the pressure plate 2. The adjusting groove 8 penetrates the upper and lower surfaces of the pressure plate 2, and the four adjusting grooves 8 are symmetrically distributed. A set of clamping members 3 is movably installed in each adjusting groove 8. The clamping members 3 are respectively mounted on a support base 9, which is connected to a synchronous drive mechanism to achieve synchronous movement of the four sets of clamping members 3 along the adjusting groove 8, thereby adapting to the clamping requirements of raw materials 16 of different sizes.

[0021] Each set of clamping components 3 includes two first clamping blocks 31 and two second clamping blocks 32, wherein the two first clamping blocks 31 are arranged diagonally, and the two second clamping blocks 32 are arranged diagonally (i.e., the first clamping blocks 31 and the second clamping blocks 32 are alternately distributed at the four corners of the pressure plate 2). Each first clamping block 31 has a sliding rod 6 vertically fixed on both sides. The sliding rod 6 has a cylindrical structure, and the two sliding rods 6 extend toward the two diagonally arranged second clamping blocks 32 respectively. Correspondingly, each second clamping block 32 has a limiting block 7 fixed on its side wall. The limiting block 7 has a through hole adapted to the sliding rod 6. The end of the sliding rod 6 away from the first clamping block 31 passes through the through hole of the limiting block 7 and extends to the outside of the second clamping block 32. Through the sliding cooperation between the sliding rod 6 and the limiting block 7, the moving trajectory of the first clamping block 31 and the second clamping block 32 is kept consistent, avoiding clamping deviation. A cavity 14 is formed inside the slide rod 6 along its length. A lead screw 15 is rotatably supported within the cavity 14 via bearings, and the axis of the lead screw 15 coincides with the axis of the slide rod 6. A drive component A4 (in this embodiment, the drive component A4 is a micro stepper motor) is fixedly mounted at the top of the slide rod 6. The output shaft of the drive component A4 is fixedly connected to the top of the lead screw 15 via a coupling, used to drive the lead screw 15 to rotate forward and backward. A scraping assembly 5 is slidably disposed within the cavity 14. The base 51 of the scraping assembly 5 is threadedly connected to the lead screw 15. When the lead screw 15 rotates, the base 51 moves along the axis of the cavity 14.

[0022] The synchronous drive mechanism is fixedly installed at the bottom of the machine body 1. It includes a drive component B11 (in this embodiment, the drive component B11 is a servo motor). The output shaft of the drive component B11 extends vertically upward and is fixedly fitted with a bevel gear (not shown in the figure). An adjusting rod 10 is fixedly connected to the center of the support base 9. The adjusting rod 10 is a vertically arranged threaded rod, and a transmission gear (not shown in the figure) is fixedly fitted at the bottom end of the adjusting rod 10. The transmission gear meshes with the bevel gear. When the drive component B11 is started, the bevel gear drives the transmission gear to rotate, which in turn drives the adjusting rod 10 to rotate synchronously. The adjusting rod 10 drives the support base 9 to move along the direction of the adjusting groove 8 through the threaded transmission, or drives the support base 9 to move horizontally through the cooperation structure with the machine body 1 (the specific design is based on the clamping requirements of the raw material 16, and the core is to achieve synchronous displacement of the four sets of clamping parts 3 along the adjusting groove 8).

[0023] The aforementioned synchronous drive mechanism can move the support base 9, thereby adjusting the distance between the clamping parts 3 to accommodate raw materials 16 of different sizes. At the same time, when the clamping parts 3 move, they can drive the slide bar 6 to move, so that the scraping component 5 can move with the clamping parts 3, thereby adapting to raw materials 16 of different sizes and facilitating the scraping of excess material on their side edges. This eliminates the need for an additional adjustment mechanism to drive the scraping mechanism to move. By adjusting the clamping mechanism according to the different sizes of raw materials 16, the scraping mechanism can adapt itself, improving the overall coordination of the equipment.

[0024] The scraping assembly 5 includes a base 51, a receiving block 52, an elastic element B55, a first scraper 53, and a second scraper 54. The base 51 is a rectangular block structure, and a sliding cavity 56 extending vertically is provided inside it. The opening of the sliding cavity 56 faces the lower surface of the pressure plate 2. The receiving block 52 is slidably embedded in the sliding cavity 56. An elastic element (a compression spring is used in this embodiment) is fixedly connected between the top of the receiving block 52 and the top of the sliding cavity 56. The elastic element is always in a pre-compressed state, providing an upward elastic force to the receiving block 52. Two sets of first scraper blades 53 are fixed to the bottom of the base 51 by bolts. The two sets of first scraper blades 53 are arranged in a mirror symmetrical manner, and the scraping end face of the first scraper blade 53 is in close contact with the lower surface of the pressure plate 2. Two sets of second scraper blades 54 are fixed to the bottom end of the receiving block 52 by bolts. The two sets of second scraper blades 54 are also arranged in a mirror symmetrical manner. The scraping end faces of the first scraper blade 53 and the second scraper blade 54 are in close contact with each other, and their blades are staggered. The second scraper blade 54 can slide along the side of the first scraper blade 53 and can partially overlap with the first scraper blade 53. Through the elastic action of the elastic member B55, the positional relationship between the first scraper blade 53 and the second scraper blade 54 can be flexibly adjusted, thereby adjusting the scraping range.

[0025] In addition, the mirror setup has multiple sets of first scraper blades 53 and second scraper blades 54, which can be adapted to the forward and reverse operation of the scraping component 5 to achieve reciprocating scraping and improve scraping efficiency.

[0026] The base 51 has an embedded heating component, and the heating temperature can be adjusted to the temperature of the molten resin. A flow channel 17 is opened on the side wall of the base 51. One end of the flow channel 17 is connected to the scraper bonding area, and the other end is connected to the storage cavity to prevent the viscous resin from clogging the flow channel 17.

[0027] Each set of clamping components 3 has a guide rod 13 fixedly connected to the bottom end of the first clamping block 31 and the second clamping block 32. The guide rod 13 is a smooth cylindrical rod 6. The support base 9 has a through guide groove corresponding to the position of the guide rod 13. The guide rod 13 slides through the guide groove to achieve guiding and limiting when the clamping component 3 moves. An elastic element A12 (in this embodiment, the elastic element A12 is a spring) is fixedly connected between the bottom end of the clamping component 3 and the upper surface of the support base 9. The elastic element A12 is sleeved on the outside of the guide rod 13. When the clamping component 3 is squeezed by an external force, the clamping component 3 compresses the elastic element A12 and moves towards the support base 9, thus "contracting".

[0028] In summary, the raw material 16 to be processed is placed on the upper surface of the pressure plate 2, the drive component B11 is started, the bevel gear rotates and drives the transmission gear and the adjusting rod 10 to rotate, the adjusting rod 10 drives the support base 9 to move in a preset direction, and then drives the four sets of clamping components 3 to move towards the raw material 16 synchronously along the adjusting groove 8; after the first clamping block 31 and the second clamping block 32 of the clamping component 3 have completed clamping the raw material 16, the stamping mechanism begins to laminate the raw material 16.

[0029] It is worth noting that, in order to facilitate the complete clamping of the multi-layer material 16, the horizontal height of the clamping member 3 and the receiving block 52 is higher than that of the multi-layer material 16.

[0030] To accommodate raw materials 16 of different sizes, the laminating plate of the stamping mechanism is designed with a larger size. Therefore, when the laminating plate is laminating the raw material 16, it will first come into contact with the clamping member 3. After being squeezed by the laminating plate, the clamping member 3 will compress the elastic member B55 and move towards the support seat 9, so that the laminating plate can contact the raw material 16 for lamination.

[0031] Similarly, the receiving block 52 is also subjected to the pressure of the laminating plate, which compresses the elastic element B55 and moves it towards the bottom of the sliding cavity 56. At this time, the second scraper 54 also moves based on the first scraper 53 and contracts under the pressure of the pressure plate 2 until the laminating plate contacts the surface of the raw material 16. As the laminating plate compresses the multi-layer raw material 16, the multi-layer raw material 16 will be compacted, thereby reducing its thickness. During this process, the clamping member 3 and the receiving block 52 can adaptively adjust according to the pressure of the laminating plate, thus adapting to the entire lamination process. Resin leaks out from between the multi-layer raw materials 16 during the lamination process. The second scraper 54 adapts to the thickness of the multi-layer raw material 16 by adjusting the relationship between the receiving block 52 and the second scraper 54, thereby improving the scraping efficiency and enhancing the scraping effect.

[0032] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Those skilled in the art can readily implement the present invention based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the present invention, utilizing the disclosed technical content, are equivalent embodiments of the present invention. Furthermore, any modifications, alterations, or variations made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the present invention.
