Description

Technical Field

[0001] This utility model relates to the technical field of guiding equipment for copper clad laminate pressing machines, and in particular to a guiding mechanism for copper clad laminate pressing machines. Background Technology

[0002] Copper clad laminate (CCL) is the core substrate for manufacturing printed circuit boards (PCBs). Lamination is a crucial step in its production process, involving pressing multiple layers of prepreg and copper foil together under high temperature and pressure. Ensuring the precise positioning of the CCL blank before it enters the press and during the initial lamination stage, without any misalignment, is key to guaranteeing the interlayer alignment accuracy, electrical performance, and final yield of the product.

[0003] Currently, copper clad laminate (CCL) pressing production lines commonly use a support worktable with positioning function to pre-position the blanks. Existing positioning technologies mainly rely on simple mechanical stops or fixed guide bars, which are usually adjusted manually to accommodate blanks of different sizes.

[0004] Although this positioning structure can be used, the total thickness of the blank will be adjusted within a certain range due to the different specifications of the copper clad laminate. The fixed-height stop cannot adapt to this change, resulting in positioning failure, affecting the positioning effect, and causing a decrease in the yield of copper clad laminate pressing. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a guiding mechanism for a copper clad laminate pressing machine to solve the problem that during the stacking process of copper clad laminate blanks, due to the different specifications of the copper clad laminates, the total thickness of the blanks will be adjusted within a certain range, and the fixed-height stop cannot adapt to this change, resulting in positioning failure, affecting the positioning effect, and causing a decrease in the yield of copper clad laminate pressing.

[0006] To achieve the above objectives, this utility model provides a guiding mechanism for a copper-clad laminate pressing machine, comprising: a frame having a worktable, the upper end of which has a vertically formed mounting groove; a negative pressure suction plate disposed in the mounting groove, the upper end of which has a negative pressure positioning end face for supporting the copper-clad laminate, the negative pressure positioning end face having a plurality of guide grooves penetrating the negative pressure suction plate vertically formed; a height adjustment assembly fixedly connected to the worktable, having an adjustment end capable of vertical movement, the adjustment end being fixedly connected to the negative pressure suction plate; and a guiding assembly having symmetrically arranged wide-side guiding units and long-side guiding units, the wide-side guiding units having at least two sets of positioning ends one capable of moving along the wide side direction of the negative pressure suction plate, the long-side guiding units having at least two sets of positioning ends two capable of moving along the long side direction of the negative pressure suction plate, the positioning ends one and positioning ends two being disposed in corresponding guide grooves, the positioning ends one being used for wide-side positioning of the board material, and the positioning ends two being used for long-side positioning of the board material.

[0007] In one alternative example, the frame includes a bottom support and a plurality of support columns, one end of which is fixedly connected to the workbench and the other end of which is fixedly connected to the bottom support.

[0008] In an optional example, the height adjustment assembly includes an adjustment bracket fixedly connected to the worktable, an adjustment screw mounted vertically on the adjustment bracket by rotation, a drive head fixed to the end of the adjustment screw, and a locking nut threaded onto the outer wall of the adjustment screw, the locking nut abutting against the adjustment bracket and fixing the adjustment screw.

[0009] In an optional example, a support block is fixed to the lower end of the negative pressure suction plate, a connecting plate is fixed to the support block, the adjusting end includes a driving nut, the driving nut is fixedly connected to the connecting plate, and the driving nut is threaded onto the outer wall of the adjusting screw.

[0010] In one alternative example, the guide groove is arranged along the long or short side of the negative pressure suction plate.

[0011] In an optional example, the guide assembly includes a support frame that is vertically connected to the frame by sliding. The wide-side guide unit and the long-side guide unit are fixedly connected to the support frame. A vertical telescopic cylinder is fixedly mounted on the frame, and the telescopic end of the vertical telescopic cylinder is fixedly connected to the support frame.

[0012] In one alternative example, at least two support rods are fixed to the lower end of the support frame, and guide rings that match the support rods are fixed to the frame.

[0013] In an optional example, the wide-side guide unit has the same structure as the long-side guide unit. The wide-side guide unit includes a sliding bracket and a guide telescopic cylinder. The sliding bracket is connected to the support frame by sliding along the width direction of the frame. The telescopic end of the guide telescopic cylinder is connected to the sliding bracket.

[0015] In one optional example, the positioning end includes a positioning guide post, on which a sidewall positioning end face is formed that abuts against the sidewall of the copper-clad laminate.

[0016] The beneficial effects of this utility model are that the controlled guiding component enables high-precision alignment of the copper-clad laminate, effectively improving the alignment accuracy of the copper-clad laminate lamination and avoiding offset during subsequent pressing. Furthermore, when changing the board specifications, no manual adjustment is required; the guiding position can be automatically changed by adjusting the positions of positioning end one and positioning end two, enabling rapid production changeover. Moreover, the cooperation of the support frame and vertical telescopic cylinder achieves the overall lifting and lowering of the guiding component, ensuring that the upper surface of the board material maintains an optimal and constant relative height, facilitating the stacking of board materials.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0022] In one embodiment, please refer to Figures 1 to 3 As shown, the present invention provides a guide mechanism for a copper clad laminate pressing machine, comprising: a frame 1, a negative pressure suction plate 2, a height adjustment component 3, and a guide component 4.

[0023] The frame 1 has a worktable 11, and the upper end of the worktable 11 has a vertical mounting slot 12 for mounting components.

[0024] The negative pressure suction plate 2 is installed in the mounting slot 12. Its upper end has a negative pressure positioning end face 21 for supporting the copper-clad laminate. Several guide grooves 22 are vertically formed along the negative pressure positioning end face 21, penetrating the negative pressure suction plate 2. The negative pressure positioning end face 21 serves as the working surface for supporting and fixing the copper-clad laminate. This working surface has a channel designed inside, which can be connected to an external vacuum system. The numerous micropores on the surface generate an adsorption force to firmly fix the copper-clad laminate. The negative pressure positioning end face 21 is located above the worktable 11, which facilitates the external transfer mechanism to grab the raw material of the board.

[0025] The height adjustment component 3 is fixedly connected to the worktable 11 and has an adjustment end 31 that can move vertically. The adjustment end 31 is fixedly connected to the negative pressure suction plate 2. The adjustment end 31 can drive the negative pressure suction plate 2 to move up and down precisely in the vertical direction. This action allows the negative pressure positioning end face 21 of the negative pressure suction plate 2 to be adjusted to a position higher than, flush with, or lower than the negative pressure positioning end face 21, in order to meet the needs of different processes such as feeding, positioning, and ejecting after pressing.

[0026] The guide assembly 4 has symmetrically arranged wide-side guide units 41 and long-side guide units 42. The wide-side guide unit 41 has at least two sets of positioning ends 411 that can move along the wide side of the negative pressure suction plate 2. The long-side guide unit 42 has at least two sets of positioning ends 421 that can move along the long side of the negative pressure suction plate 2. Positioning ends 411 and 421 are positioned within corresponding guide grooves 22. Positioning ends 411 are used for wide-side positioning based on the material's properties, and positioning ends 421 are used for long-side positioning based on the material's properties. During operation, depending on the size of the copper-clad laminate, positioning ends 411 and 421 are driven to move synchronously in opposite directions, thereby centering and clamping the material from four sides.

[0027] Specifically, this example uses the controlled guide component 4 to achieve high-precision alignment of the copper clad laminate, effectively improving the alignment of the copper clad laminate lamination, avoiding offset during subsequent pressing, and when changing the board specifications, no manual adjustment is required. By adjusting the positions of positioning end one 411 and positioning end two 421, the guide position can be automatically changed, enabling rapid production changeover.

[0028] In an optional example, please refer to Figures 1 to 3 As shown, the frame 1 includes a bottom support 13 and several support columns 14. One end of the support column 14 is fixedly connected to the worktable 11 by bolts, and the other end of the support column 14 is fixedly connected to the bottom support 13 by bolts.

[0029] Specifically, this example disassembles the frame 1 into a separate structure consisting of a workbench 11, a bottom support 13, and a support column 14, ensuring that the frame 1 has extremely high rigidity and stability and reducing the assembly difficulty of the frame 1.

[0030] In an optional example, please refer to Figures 1 to 4 As shown, the height adjustment assembly 3 includes an adjustment bracket 32 ​​fixedly connected to the worktable 11 by bolts. An adjustment screw 33 is vertically mounted on the adjustment bracket 32 ​​via a bearing connection. A drive head 34 is fixed to the end of the adjustment screw 33. A locking nut 35 is threaded onto the outer wall of the adjustment screw 33, abutting against the adjustment bracket 32 ​​and fixing the adjustment screw 33. When the adjustment screw 33 is rotated by the drive head 34, it pushes the negative pressure suction plate 2 connected to the end of the adjustment screw 33 to rise or fall. After adjusting to the desired height, the locking nut 35 can be locked, serving to prevent loosening and enhance rigidity.

[0031] Specifically, in this example, the vertical movement of the negative pressure suction plate 2 is controlled by rotating the adjusting screw 33, which ensures the positioning accuracy of the negative pressure positioning end face 21, avoids displacement of the height of the material, ensures the positional stability of the material during the transfer process, and effectively improves the product lamination alignment.

[0032] In an optional example, please refer to Figures 1 to 4 As shown, a support block 23 is fixed to the lower end of the negative pressure suction plate 2 by bolts. A connecting plate 24 is fixed to the support block 23 by bolts. The adjusting end 31 includes a drive nut, which is fixedly connected to the connecting plate 24 by bolts. The drive nut is also threaded onto the outer wall of the adjusting screw 33. When the adjusting screw 33 is rotated by the drive head 34, the adjusting screw 33 drives the connecting plate 24 to move via the drive nut. The connecting plate 24 then drives the support block 23 to move, and the support block 23 then drives the negative pressure suction plate 2 to move, thus achieving height adjustment of the negative pressure suction plate 2.

[0033] Specifically, this example uses a combination of adjusting screw 33 and drive nut for transmission, and transmits the motion smoothly to negative pressure suction plate 2 through support block 23 and connecting plate 24, ensuring the height synchronization and position accuracy of the lifting process.

[0034] In an optional example, please refer to Figures 1 to 4 As shown, the guide groove 22 is set along the long or short side of the negative pressure suction plate 2.

[0035] Specifically, in this example, the guide groove 22 adopts an orthogonal layout, providing a clear motion trajectory for positioning end 1 411 and positioning end 2 421.

[0036] In an optional example, please refer to Figures 1 to 4 As shown, the guide assembly 4 includes a support frame 43, which is vertically connected to the frame 1 via a sliding connection. The wide-side guide unit 41 and the long-side guide unit 42 are fixedly connected to the support frame 43. A vertical telescopic cylinder 15 is fixedly mounted on the frame 1 via bolts, and the telescopic end of the vertical telescopic cylinder 15 is fixedly connected to the support frame 43. The vertical telescopic cylinder 15 is electrically driven and its height can be adjusted according to the thickness of the copper-clad laminate.

[0037] Specifically, this example achieves the overall lifting and lowering of the guide assembly 4 through the cooperation of the support frame 43 and the vertical telescopic cylinder 15, ensuring that the upper surface of the sheet material maintains an optimal and constant relative height, which facilitates the stacking of sheet material. This allows for effective and consistent guidance and positioning of sheet materials of different thicknesses, effectively eliminating positioning failures or edge collisions caused by changes in stacking height, and greatly improving the alignment accuracy and yield of multi-layer blank pressing.

[0038] In an optional example, please refer to Figures 1 to 4 As shown, at least two support rods 44 are fixed to the lower end of the support frame 43 by bolt connection, and a guide ring 45 matching the support rods 44 is fixed to the frame 1 by bolt connection.

[0039] Specifically, in this example, the cooperation between the support rod 44 and the guide ring 45 provides the support frame 43 with high-strength anti-torque and anti-eccentric load capabilities, ensuring the structural rigidity and positional accuracy of the guide assembly 4, thereby further guaranteeing the alignment quality of the pressed product.

[0040] In an optional example, please refer to Figures 1 to 5 As shown, the wide-side guide unit 41 and the long-side guide unit 42 have the same structure. The wide-side guide unit 41 includes a sliding bracket 412 and a guide telescopic cylinder 413. The sliding bracket 412 is connected to the support frame 43 by sliding along the width direction of the frame 1. The telescopic end of the guide telescopic cylinder 413 is connected to the sliding bracket 412 by bolts. The positioning end 411 is fixed to the upper end of the sliding bracket 412 by bolts. The guide telescopic cylinder 413 is electrically driven and can adjust the position of the sliding bracket 412 according to the width and height dimensions of the copper-clad laminate, so that the positioning end 411 can accurately position the raw material of the board.

[0041] Specifically, in this example, the cooperation between the sliding bracket 412 and the guide telescopic cylinder 413 enables precise adjustment of the positioning end 411, ensuring the positioning accuracy of the billet and improving the alignment accuracy and yield of multi-layer billet pressing.

[0042] In an optional example, please refer to Figures 1 to 5 As shown, the lower end of the sliding bracket 412 is fixed with a sliding block 414 by bolt connection. The wide-side guide unit 41 includes at least two sliding rods 415. The sliding rods 415 are fixedly connected to the support frame 43 by bolt connection. The sliding block 414 is slidably fitted onto the outer wall of the sliding rod 415.

[0043] Specifically, the cooperation between the sliding block 414 and the sliding rod 415 in this example provides the sliding bracket 412 with high-strength anti-torque and anti-eccentric load capabilities, ensuring the structural rigidity and positional accuracy of the wide-side guide unit 41 and the long-side guide unit 42, thereby further guaranteeing the alignment quality of the pressed product.

[0044] In an optional example, please refer to Figures 1 to 5 As shown, positioning end 411 includes a positioning guide post, and the positioning guide post has a side wall positioning end face 4111 that abuts against the side wall of the copper-clad laminate. The structure of positioning end 411 is the same as that of positioning end 421.

[0045] Specifically, this example achieves stable contact between the sidewall of the board material and the sidewall by opening a sidewall positioning end face 4111 on the sidewall of the positioning guide post, thereby dispersing the contact stress and greatly reducing the risk of indentation or damage to the edge of the copper-clad laminate while achieving precise positioning.

[0046] In summary, this invention, through the controlled guide component 4, enables high-precision alignment of copper-clad laminates, effectively improving the alignment accuracy of copper-clad laminate lamination and preventing offset during subsequent pressing. Furthermore, when changing board specifications, no manual adjustment is required; the guide position can be automatically changed by adjusting the positions of positioning end 411 and positioning end 421, enabling rapid production changeover. Moreover, through the cooperation of the support frame 43 and the vertical telescopic cylinder 15, the guide component 4 achieves overall lifting and lowering, ensuring that the upper surface of the board material maintains an optimal and constant relative height, facilitating the stacking of board materials. This allows for effective and consistent guidance and positioning of boards of different thicknesses, effectively eliminating positioning failures or edge collisions caused by changes in stacking height, and greatly improving the alignment accuracy and yield of multi-layer blank pressing.
