Description

Technical Field

[0001] This invention belongs to the field of copper clad laminate production technology, and particularly relates to a pressing and fixing device for copper clad laminate production and processing. Background Technology

[0002] Copper-clad laminates (CCLs) serve as the carrier and framework for integrated circuits. The printed circuit boards (PCBs) made from CCLs provide the mechanical mounting base, stable power supply, and electrical interconnection for chips, enabling various integrated circuits to work collaboratively. In the production and processing of CCLs, clamping and fixing devices are key process equipment used to fix the CCLs during drilling, milling, welding, and inspection processes, preventing displacement or vibration and thus ensuring processing accuracy and product quality. Existing technologies commonly employ clamping and fixing methods including mechanical clamping, vacuum adsorption, and magnetic fixing.

[0003] Traditional mechanical clamping methods typically apply pressure through point or line contact, resulting in uneven pressure distribution. This can easily lead to excessive mechanical stress near the clamping point, causing problems such as micro-deformation of the copper-clad laminate (CCL), interlayer delamination, or internal cracks. Furthermore, when the CCL position needs to be adjusted during the clamping process, the lower end face of the CCL is prone to wear. This deformation not only affects the positioning accuracy of the current process (such as drilling misalignment) but may also accumulate errors in subsequent processes. Together with the wear during adjustment, this reduces the overall product yield. In addition, current mechanical clamping methods are prone to micro-slippage of the CCL in high-speed cutting or high-vibration processing environments.

[0004] Therefore, the present invention provides a clamping and fixing device for copper clad laminate production and processing, which can solve the above problems and achieve uniform and stable clamping function to meet the needs of high-precision copper clad laminate manufacturing. Summary of the Invention

[0005] To address the aforementioned problems, the present invention provides a clamping and fixing device for copper clad laminate production and processing, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solution: This invention provides a clamping and fixing device for copper-clad laminate (CCL) production and processing, comprising: a worktable, a lower support structure, and a side clamping structure. The worktable has a strip-shaped through-slot extending along its length on its tabletop, and the inside of the strip-shaped through-slot is also uniformly provided with connecting slots communicating with it. The lower support structure is located at the lower end of the tabletop and is used to selectively penetrate the strip-shaped through-slot or the connecting slot to support or position the CCL on the upper end of the tabletop; it includes a guide rod and a push block. The side clamping structure is located on both sides of the worktable and is used to laterally clamp the CCL. The lower support structure includes a switchable first support mode and... In the first clamping mode, the guide rod of the lower support structure protrudes from the upper surface of the table panel and forms line contact with the lower end of the copper-clad laminate; in the first clamping mode, the push block of the lower support structure protrudes from the upper surface of the table panel and forms surface contact with the lower end of the copper-clad laminate; the side clamping structure includes a swingable side support assembly, which has a second support mode and a second clamping mode; it includes a positioning post and a pressure ring sleeve; in the second support mode, the positioning post of the side support assembly contacts the side wall of the copper-clad laminate for centering adjustment and side extrusion fixation; in the second clamping mode, the pressure ring sleeve of the side support assembly corresponds vertically to the push block of the lower support structure, and together they perform zoned clamping of the copper-clad laminate.

[0007] According to an advantageous embodiment, the lower support structure includes a U-shaped frame, a pushing block, and a linkage mechanism. The U-shaped frame is limited and disposed inside the strip-shaped through groove, and the guide rod is fixedly disposed inside the U-shaped frame. The pushing block is slidably disposed inside the connecting groove. The linkage mechanism is disposed inside the worktable and is used to drive the U-shaped frame and the pushing block to link together, so as to realize the switching between the first support mode and the first pressing mode.

[0008] According to an advantageous embodiment, the linkage mechanism includes: an adjustable-length support column installed at the lower end of the push block, an auxiliary plate installed at the lower end of the support column, and two fixed guide columns and a square rod passing through the auxiliary plates in all connecting slots connected to the same through slot. The fixed guide columns are slidably disposed inside the workbench. Several sets of connecting rods are respectively hinged to the outer wall of the square rod and the lower end of the U-shaped frame through connectors. The length of the connecting rod connected to the lower end of the square rod in each set of connecting rods is greater than the length of the connecting rod connected to the lower end of the U-shaped frame. The lower ends of the several sets of connecting rods are all hinged to the slide plate.

[0009] According to an advantageous embodiment, the workbench is further provided with a double-headed cylinder. Both telescopic ends of the double-headed cylinder are fixedly mounted with connecting plates. Each connecting plate on each side is fixedly provided with a number of fixing rods that correspond one-to-one with the number of connecting rod groups. Each fixing rod on each side fixes the slide plate corresponding to its position on that side.

[0010] According to an advantageous embodiment, the side clamping structure includes a bidirectional threaded rod mounted on the side wall of the worktable via two lugs, the bidirectional threaded rod being connected to the lugs via bearings; a single-axis servo motor is embedded inside one of the lugs, the output shaft of the single-axis servo motor being connected to the shaft head of the bidirectional threaded rod at that position via a coupling; the two sides of the bidirectional threaded rod have opposite thread directions.

[0011] According to an advantageous embodiment, the bidirectional threaded rod is symmetrically provided with movable blocks by means of threaded connection, and the side wall of the worktable is provided with a sliding groove for the movable blocks to limit sliding; the movable blocks are provided with vertically arranged dual-axis servo motors, and both of their output shafts are connected to fixed plates. The fixed plates are provided with side support components with adjustable extension length by means of bolt connection.

[0012] According to an advantageous embodiment, the side support assembly includes a limiting post slidably disposed inside a fixed plate, the limiting post being fixed to the fixed plate by a nut threaded to the side wall of the fixed plate; a support plate is fixedly installed at the other end of the limiting post, a positioning post is fixedly installed on the support plate, a conical sleeve is fixedly installed on the lower outer wall of the positioning post, and a pressure ring sleeve that mates with the conical sleeve is also provided on the lower side of the conical sleeve, the pressure ring sleeve is sleeved on the outer wall of the conical sleeve and the positioning post, and a conical groove that mates with the outer wall of the conical sleeve is provided at the upper end of the pressure ring sleeve, a buffer spring is connected between the pressure ring sleeve and the conical sleeve, and a rubber ring for pressing the upper surface of the clamped copper-clad laminate is provided on the lower end face of the pressure ring sleeve.

[0013] According to an advantageous embodiment, the bottom end of the positioning post is also provided with a rubber sleeve via a bearing that presses against the sidewall of the copper-clad laminate.

[0014] According to an advantageous embodiment, a rubber pad is provided on the end face of the push block that contacts the copper-clad laminate.

[0015] According to an advantageous embodiment, the upper surface of the tabletop is further provided with a cross groove, in which a cross scale ruler can be installed.

[0016] Compared with the prior art, the pressing and fixing device for copper clad laminate production and processing provided in this embodiment of the invention has the following beneficial effects:

[0017] 1. This invention employs a "zonal collaborative clamping" mechanism. Multiple adjustable side support components of the side clamping structure clamp the sidewalls of the copper-clad laminate (CCL) through extrusion. Simultaneously, multiple push blocks of the lower support structure (which cooperate with the pressure rings on the side support components to form multiple "triangular" support and clamping points on the CCL) create multiple "triangular" areas for support and clamping. By adopting a zoned, multi-point clamping method, the pressure is evenly distributed to various areas of the CCL, greatly avoiding excessive mechanical stress in local areas. This fundamentally solves the quality problems of micro-deformation, interlayer peeling, or internal cracks caused by uneven clamping force in the CCL, providing a solid foundation for high-precision processing.

[0018] 2. The lower support structure of this invention features a dual-mode switching function. During the position adjustment stage, the guide rod protrudes by retracting the double-headed cylinder, converting the surface contact between the copper-clad laminate and the worktable into a line contact. This significantly reduces frictional resistance during lateral adjustment and effectively prevents scratches and wear on the lower surface of the copper-clad laminate. During the clamping and fixing stage, the guide rod retracts, the push block extends, and together with the upper pressure ring sleeve, a stable clamping process is achieved. This "slide first, then fix" process design ensures smooth and damage-free position adjustment while guaranteeing a firm and precise final fixation. This reduces waste caused by wear and positioning deviations, thereby improving the processing yield. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will be described in further detail.

[0027] Please refer to the following: Figure 1 A clamping and fixing device for copper clad laminate (CCL) production and processing includes a worktable 1, a lower support structure 2, and a side clamping structure 3. The worktable 1 has a U-shaped structure, and the tabletop 11 of the worktable 1 is a detachable structure. The upper end of the tabletop 11 has strip-shaped through grooves 12 extending along its length direction along its width direction. The inside of the strip-shaped through grooves 12 also has connecting grooves 13 that communicate with it along its length direction. The lower support structure 2 is located at the lower end of the tabletop 11 and is used to support and position the CCL placed on the upper end of the tabletop 11 through the strip-shaped through grooves 12 and the connecting grooves 13. The side clamping structure 3 is located on both sides of the worktable 1 and is used to laterally squeeze and clamp the CCL on the upper end of the tabletop 11. It works together with the lower support structure 2 to jointly clamp the upper and lower surfaces of the CCL on the upper end of the tabletop 11 in sections.

[0028] Before using this device to press and fix the copper-clad laminate for production processing, firstly, the workbench 1 is installed at the feeding end of the existing copper-clad laminate conveying equipment, and the existing copper-clad laminate processing equipment is kept directly above the workbench 1. At the same time, according to the requirements of the copper-clad laminate to be processed, the operator inputs the corresponding parameters (copper-clad laminate size, clamping force, etc.) on the operation panel on the outside of the workbench 1. During operation, the copper-clad laminate to be processed is intermittently conveyed to the workbench 11 by the existing copper-clad laminate conveying equipment. The lower support structure 2 and the side clamping structure 3 work together to adjust the position of the copper-clad laminate to be processed. Then, the copper-clad laminate is squeezed and fixed and pressed in multiple sections. Subsequently, the existing copper-clad laminate processing equipment is used for processing operations (such as drilling, milling, welding, inspection, etc.). After completion, the lower support structure 2 and the side clamping structure 3 release the processed copper-clad laminate together and convey it to the next process by the existing copper-clad laminate conveying equipment.

[0029] To verify at any time whether the copper-clad laminate, after being positioned by the side clamping structure 3, is in the center of the tabletop 11, refer to... Figure 1 A cross groove is provided on the upper surface of the table panel 11, and a cross scale 15 is installed in the cross groove. The upper surface of the cross scale 15 is flush with the upper surface of the table panel 11, so as not to affect the movement of the copper clad laminate. During the copper clad laminate production stage, external monitoring equipment (such as a CCD camera) monitors the data in real time and compares the obtained data with the preset data. Once a deviation is found, the abnormality can be detected in time.

[0030] After the copper-clad laminate to be processed is conveyed to the upper end of the table panel 11 using the existing copper-clad laminate conveying equipment, the side clamping structure 3 starts to work to adjust the position of the side wall of the copper-clad laminate to be centered before clamping it. (See reference...) Figure 1 The side clamping structure 3 includes a bidirectional threaded rod 31 mounted on the side wall of the worktable 1 via two lugs. The bidirectional threaded rod 31 is connected to the lugs via bearings. A single-axis servo motor 32 is embedded inside one of the lugs. The output shaft of the single-axis servo motor 32 is connected to the shaft head of the bidirectional threaded rod 31 at that position via a coupling. The threads on both sides of the bidirectional threaded rod 31 are opposite in direction. Moving blocks 33 are symmetrically arranged on the bidirectional threaded rod 31 via threaded connections. The side wall of the worktable 1 is provided with a sliding groove 14 for the moving blocks 33 to be limited and slid. A vertically arranged dual-axis servo motor 34 is installed inside the moving block 33. Both output shafts of the dual-axis servo motor 34 are connected to a fixed plate 35. The two output shafts of the dual-axis servo motor 34 are respectively equipped with independent servo drivers and can be driven independently. The fixed plate 35 is provided with a side support assembly 36 with adjustable extension length via bolt connections.

[0031] Before operation, based on the copper-clad laminate dimensions input on the control panel, the single-axis servo motor 32 drives the bidirectional threaded rod 31 to rotate, adjusting the distance between the two moving blocks 33 connected to it to match the length of the copper-clad laminate. During operation, the dual-axis servo motor 34 drives the upper and lower fixed plates 35 to rotate, shortening the angle between the two fixed plates 35. During the rotation of the fixed plates 35, the side support assembly 36 swings synchronously until it contacts the side wall of the copper-clad laminate. As the angle between them continues to decrease, it synchronously moves the copper-clad laminate to adjust its position. It should be noted that each of the dual-axis servo motors 34 is internally equipped with a device for monitoring the two input parameters. The sensor that outputs torque values ​​from the output shaft will continue to rotate after the side support assembly 36 contacts the side wall of the copper-clad laminate, pushing the copper-clad laminate to move and adjust its position until all the side support assemblies 36 are in contact with the side wall of the copper-clad laminate. At this time, all the values ​​output by the sensor are the same as the set threshold, indicating that the centering and extrusion fixing is completed. It should be noted that during the position adjustment of the copper-clad laminate, whether the position in the width direction or the length direction is centered first, the sensor detection data values ​​on the side support assembly 36 in the corresponding position direction will be the same and reach the set threshold. At this time, the side support assembly 36 in the corresponding position direction will stop extruding.

[0032] See Figure 3 The side support assembly 36 includes a limiting post 361 slidably disposed inside the fixed plate 35. The limiting post 361 is fixed to the fixed plate 35 by a nut 362 threadedly connected to the side wall of the fixed plate 35. A support plate 363 is fixedly installed at the other end of the limiting post 361. A positioning post 364 is fixedly installed on the support plate 363. In order to better perform extrusion fixing for copper clad laminates with different aspect ratios, before fixing the corresponding copper clad laminate, the length ratio of the two side support assemblies 36 on the same dual-axis servo motor 34 can be further adjusted for the copper clad laminate of that model. Specifically, the adjustment can be made by loosening the nut 362 and then pulling the limiting post 361.

[0033] See Figure 6 The bottom end of the positioning post 364 is also provided with a rubber sleeve 368 through a bearing, which makes contact with the side wall of the copper-clad laminate. The purpose is to reduce the wear of the side wall of the copper-clad laminate caused by the fixed friction of the positioning post 364 when the positioning post 364 is driven by the dual-axis servo motor 34 to swing and contact the side wall of the copper-clad laminate during the process of pushing the copper-clad laminate to move. At the same time, after the position adjustment is completed, during the process of clamping by multiple positioning posts 364, the deformation of the rubber sleeve 368 can increase the contact area with the copper-clad laminate, further ensuring the clamping effect, and at the same time avoiding the damage to the copper-clad laminate caused by the direct hard contact of the positioning post 364.

[0034] The side support assembly 36 can side-extrude and fix the copper-clad laminate in the length and width directions of its sidewall, effectively avoiding deformation of the copper-clad laminate caused by top and bottom point pressure. The side extrusion fixing can further limit the position of the copper-clad laminate and prevent it from displacing during the current process.

[0035] See Figure 4 and Figure 5 The lower support structure 2 includes a U-shaped frame 21 that is limited and disposed inside the strip-shaped through groove 12. A guide rod 22 with chamfered ends is fixedly disposed inside the U-shaped frame 21. The guide rod 22 is used to tangent to the copper-clad laminate placed on the tabletop 11, reducing the resistance to position adjustment during the clamping process of the copper-clad laminate. The lower support structure 2 also includes a push block 23 that is slidably disposed inside the connecting groove 13 and a linkage mechanism disposed inside the worktable 1 for driving the U-shaped frame 21 and the push block 23 to move together. The end face of the push block 23 that contacts the copper-clad laminate is provided with a rubber pad. The linkage mechanism includes a rubber pad mounted on the lower end of the push block 23. The length of the adjustable support column 24 is provided. The lower end of the support column 24 is equipped with an auxiliary plate 25. The auxiliary plates 25 in all the connecting slots 13 connected to the same through slot 12 are provided with two fixed guide columns 26 and a square rod 27. The fixed guide columns 26 are slidably arranged inside the workbench 1. The outer wall of the square rod 27 and the lower end of the U-shaped frame 21 are respectively hinged with several sets of connecting rods 28 through connectors. The length of the connecting rod 28 connected to the lower end of the square rod 27 in each set of connecting rods 28 is greater than the length of the connecting rod 28 connected to the lower end of the U-shaped frame 21. The lower ends of several sets of connecting rods 28 are all hinged on the slide plate 29.

[0036] Continue reading Figure 5 The workbench 1 is also equipped with a double-headed cylinder 201. Both telescopic ends of the double-headed cylinder 201 are fixedly installed with connecting plates 202. Each side of the connecting plate 202 is fixedly equipped with a number of fixed rods 203 that correspond one-to-one with the number of connecting rods 28. Each side of the fixed rod 203 fixes the slide plate 29 corresponding to its position on that side.

[0037] To reduce the frictional resistance between the copper-clad laminate and the platform 11 during the movement of the copper-clad laminate when it is clamped by the side clamping structure 3, and to avoid wear on the lower end face of the copper-clad laminate affecting its performance, refer to... Figure 5 The double-headed cylinder 201 retracts, causing the slide plates 29 on both sides to move closer together. As the slide plates 29 move closer together, the upper end of the guide rod 22 protrudes slightly from the surface of the table panel 11, thus changing the surface contact between the table panel 11 and the lower end of the copper-clad laminate to a line contact between the guide rod 22 and the lower end of the copper-clad laminate. This reduces the frictional resistance during the movement of the copper-clad laminate and further reduces the wear caused to the copper-clad laminate. At the same time, the two ends of the guide rod 22 are chamfered to prevent the copper-clad laminate from being scratched during the movement of the copper-clad laminate by the conveying equipment.

[0038] After the copper-clad laminate is centered and clamped, the double-headed cylinder 201 extends, causing the sliding plates 29 on the left and right sides to move away from each other. As the sliding plates 29 move away from each other, the guide rod 22 gradually retracts into the strip groove 12, and at the same time gradually drives the push block 23 to protrude out of the connecting groove 13 until it contacts the lower end face of the copper-clad laminate.

[0039] It should be noted that, in order to ensure that the upper and lower end faces can be further pressed and fixed after the copper-clad laminate sidewalls are clamped and squeezed, please refer to [reference needed]. Figure 6 The lower outer wall of the positioning post 364 is threaded with a tapered sleeve 365, and the lower side of the tapered sleeve 365 is also provided with a pressure ring sleeve 366 that cooperates with it. The pressure ring sleeve 366 is sleeved on the outer wall of the tapered sleeve 365 and the positioning post 364, and the upper end of the pressure ring sleeve 366 is provided with a tapered groove that cooperates with the outer wall of the tapered sleeve 365. A buffer spring 367 is connected between the pressure ring sleeve 366 and the tapered sleeve 365. The lower end face of the pressure ring sleeve 366 is provided with a rubber ring for pressing the upper end face of the clamped copper-clad board.

[0040] The pressure ring sleeve 366 and the push block 23 provided on the lower end face of the positioning post 364 can limit the vertical movement of the copper-clad laminate. The push block 23 moves upward to complete the clamping and fixing of the copper-clad laminate. To further reduce damage to the copper-clad laminate during clamping, the position of the tapered sleeve 365 is pre-adjusted according to the thickness of the copper-clad laminate. This ensures that the buffer spring 367 is at a set pressure after the copper-clad laminate is clamped by the pressure ring sleeve 366 and the push block 23. To maintain the pressure value of the buffer spring 367 within a suitable range, a pressure sensor can be installed inside the tapered groove for monitoring during assembly. During the clamping process of the pressure ring sleeve 366 and the push block 23, the pressure ring sleeve 366... The tapered groove on the 6th plate, in conjunction with the outer wall of the tapered sleeve 365, further ensures the stability of the pressure ring sleeve 366. Multiple push blocks 23 at the lower end of the copper-clad laminate work together with the pressure ring sleeve 366 to achieve triangular-structured, segmented upper and lower clamping and fixing of the copper-clad laminate corner areas. This further enhances the fixing effect without affecting subsequent processing operations. Combined with pressure sensor data monitoring, it ensures uniform clamping force, effectively preventing micro-deformation, interlayer peeling, or internal cracks in the clamped copper-clad laminate. Simultaneously, it improves the positioning accuracy of current processes (such as drilling, milling, welding, and inspection), reduces accumulated errors in subsequent processes, and improves the overall product qualification rate.

[0041] Meanwhile, to ensure the stability of long copper-clad laminates during processing in special processing environments (such as high-speed cutting or drilling with high vibration), and to prevent slippage of the copper-clad laminates, clamping structures 4 are provided on both sides of the worktable 1. (See reference...) Figure 2 and Figure 4The clamping structure 4 uses an existing electric push rod 41 in conjunction with a roller-equipped extrusion head 42 connected to its telescopic end to clamp the copper-clad laminate in the middle. In this embodiment, the clamping structure 4 also includes an L-shaped frame 43 bolted to the side wall of the workbench 1. The L-shaped frame 43 has a through hole that passes through the bidirectional threaded rod 31, and the L-shaped frame 43 is located in the middle of the two moving blocks 33. The clamping structures 4 on both sides further reinforce the clamping effect of the copper-clad laminate.

[0042] See Figure 1 The upper surfaces of both sides of the worktable 1 are also equipped with protective covers for the bidirectional threaded rod 31 by bolts. The covers are also easy to remove and replace the worn bidirectional threaded rod 31. This helps to maintain the accuracy of the copper-clad laminate's fixed position and improve the precision of its subsequent processing.

[0043] Specifically, when using this clamping and fixing device to clamp and fix copper-clad laminates during the production and processing:

[0044] The first step is to switch the guide rod 22 to contact the lower end of the copper-clad board that is conveyed to the upper end of the table panel 11 through the lower support structure 2 to form the first support mode, thereby reducing the frictional resistance during the movement of the side clamping structure 3.

[0045] The second step is to use the side support assembly 36 to perform multi-point sectional compression and fixation on the copper-clad board that is conveyed to the upper end of the table panel 11 (i.e., the second support mode of the side support assembly 36).

[0046] The third step involves switching the push block 23 to contact the lower end face of the copper clad laminate through the lower support structure 2 to form the first pressing mode, so that the push block 23 and the lower end face of the pressure ring 366 in the side support assembly 36 cooperate together (i.e. the second pressing mode of the side support assembly 36) to complete the pressing and fixing of the upper and lower end faces of the copper clad laminate.

[0047] In the second support mode, the positioning post 364 of the side support assembly 36 contacts the side wall of the copper clad laminate for centering adjustment and side extrusion fixation.

[0048] In the second clamping mode, the pressure ring 366 of the side support assembly 36 corresponds vertically to the push block 23 of the lower support structure 2, and together they clamp the copper-clad laminate in sections.

[0049] It should be noted that copper clad laminates of the same model are produced in the same batch during the production and processing of copper clad laminates. Therefore, adjusting the extension length of the side support component 36 relative to the fixed plate 35 and adjusting the position of the tapered sleeve 365 according to the thickness of the copper clad laminate are low-frequency operations, which will not make the operation of this clamping and fixing device complicated during use.
