Description

Technical Field

[0001] This utility model relates to the field of copper plate processing technology, and in particular to a high-toughness copper-clad laminate forming device. Background Technology

[0002] With the rapid development of electronic technology, copper clad laminates, as the basic material for printed circuit boards (PCBs), have increasingly higher requirements for performance and quality. In the production process of copper clad laminates, the forming process is one of the key links, which directly affects important performance indicators such as the dimensional accuracy, flatness, and integrity of the internal structure of the copper clad laminate.

[0003] Traditional copper clad laminate (CCL) forming equipment is often simple in structure and single in function. For example, when applying pressure to form CCLs, it is difficult to accurately control the position and force of the pressure, resulting in inconsistent quality of the formed CCLs. Moreover, the method of fixing the CCLs during the forming process is not stable enough, which can easily lead to displacement of the CCLs, thus affecting the product qualification rate. In addition, traditional equipment is not convenient to operate and is inefficient when adjusting the relative position of the pressure component and the CCLs, and cannot meet the needs of large-scale, high-efficiency production.

[0004] To address this, we propose a high-toughness copper-clad laminate forming device. Utility Model Content

[0005] (1) The main purpose of this utility model is to provide a high-toughness copper clad laminate forming device. In order to prevent the problems of poor copper clad laminate forming quality and low production efficiency caused by the defects of the structure and function of traditional copper clad laminate forming devices, the device can improve the accuracy, stability and production efficiency of copper clad laminate forming and effectively solve the problems in the background art.

[0006] (2) To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] (3) A high-toughness copper-clad laminate forming device, comprising a box body, a bracket welded to the top of the box body, a first motor fixedly installed at the middle of the top of the bracket, the output shaft of the first motor passing through the bracket and fixedly connected to a first threaded rod, a first threaded sleeve movably passing through the top of the box body, the first threaded sleeve being threadedly connected to the first threaded rod, a support plate fixedly connected to the bottom of the first threaded sleeve, a hydraulic mechanism being provided below the support plate, and two symmetrical clamping mechanisms being provided on the inner wall of the bottom of the box body and obliquely below the hydraulic mechanism;

[0008] (4) The bottom two sides of the first screw sleeve are hinged with movable plates. The top inner wall of the box is provided with two sliding mechanisms. The side of the movable plate away from the hinge is movably connected to the sliding mechanism. The side of the movable plate near the first screw sleeve is provided with a pull rope. The end of the pull rope away from the movable plate is fixedly installed with a first spring. The lower part of the first screw sleeve is provided with a guide hole. The first spring is movably disposed in the guide hole. The side of the movable plate near the first screw sleeve is provided with a fixed head. The fixed head is fixedly connected to the movable plate. One end of the pull rope is fixedly connected to the fixed head. The bottom of the guide hole is fixedly installed with a winding seat. The pull rope is movably wound on the winding seat.

[0009] (5) The sliding mechanism includes a slide rail, which is set on the inner wall of the top of the box and is integrally formed with the box. The slide rail has a T-shaped cross section. A slider is slidably sleeved on the outside of the slide rail. The slider is hinged to the movable plate. Limiting blocks are provided at both ends of the slide rail. The limiting blocks are integrally formed with the slide rail.

[0010] (6) By adopting the above technical solution, when the first motor is started, its output shaft drives the first threaded rod to rotate. Since the first threaded sleeve is threadedly connected to the first threaded rod, the rotation of the first threaded rod will cause the first threaded sleeve to move upward or downward along its axis. During the downward movement of the first threaded sleeve, the support plate fixedly connected to its bottom end will also rise or fall synchronously. The hydraulic mechanism set below the support plate will also gradually move away from or closer to the location of the copper-clad laminate material to be processed inside the box as the support plate moves upward or downward, so as to carry out related forming pressure operations, etc. When the first threaded sleeve moves upward, the movable plates hinged on both sides of its bottom will change angle as the first threaded sleeve moves upward. This is because the side of the movable plate away from the hinge is connected to the sliding mechanism set on the inner wall of the top of the box. In the moving connection, for the sliding mechanism, the slide rail is fixed on the inner wall of the top of the housing, and the slider is sleeved on the outside of the slide rail and hinged to the movable plate. When the first screw sleeve moves down and drives the movable plate to move, the movable plate will pull the slider hinged to it to slide on the slide rail. The limit blocks at both ends of the slide rail can prevent the slider from sliding out of the slide rail, ensuring the stability and controllability of the movable plate's movement. A pull rope is provided on the side of the movable plate near the first screw sleeve. One end of the pull rope is fixedly connected to the fixed head fixed on the movable plate, and the other end is fixedly installed with the first spring. In the initial state, the first spring is in a naturally extended state, and the pull rope is also in a relatively relaxed state. When the movable plate changes angle as the first screw sleeve moves up, the movable plate will pull the pull rope through the fixed head. The pull rope will go around the winding seat and pull the first spring, so that the first spring is gradually stretched.

[0011] (7) During the entire molding process, when the hydraulic mechanism applies pressure to the copper-clad laminate for molding, the clamping mechanism plays a role in fixing the position of the copper-clad laminate, preventing unnecessary displacement of the copper-clad laminate when subjected to external forces such as pressure, thereby ensuring the accuracy and stability of the molding operation.

[0012] (8) Further, the hydraulic mechanism includes a hydraulic press fixedly installed at the middle of the bottom end of the support plate, and a pressure plate is fixedly installed at the output end of the hydraulic press.

[0013] (9) By adopting the above technical solution, the hydraulic press is started, and the output end of the hydraulic press moves the pressure plate downward to apply pressure to the copper-clad laminate.

[0014] (10) Further, the clamping mechanism includes a second threaded rod and a fixed seat. The second threaded rod is rotatably connected to one side of the inner wall of the fixed seat via a bearing. A second motor is fixedly installed on one side of the fixed seat. The output shaft of the second motor passes through the fixed seat and is fixedly connected to the second threaded rod.

[0015] (11) By adopting the above technical solution, when the second motor starts, its output shaft begins to rotate. Since the output shaft of the second motor passes through the fixed seat and is fixedly connected to the second threaded rod, the rotational motion of the second motor is directly transmitted to the second threaded rod, causing the second threaded rod to rotate around its own axis.

[0016] (12) Further, the fixed seat has a first sliding groove inside, and a second threaded sleeve is movably passed through the side of the first sliding groove away from the second motor. The second threaded sleeve is threadedly connected to the second threaded rod.

[0017] (13) By adopting the above technical solution, when the second threaded rod rotates, based on the thread transmission principle, the second threaded sleeve will move axially on the second threaded rod. Because the second threaded sleeve is restricted by the first sliding groove, it can only move along the direction defined by the first sliding groove, that is, along the direction parallel to the axial direction of the second threaded rod. This ensures the stability and directionality of the movement of the second threaded sleeve.

[0018] (14) Further, a support frame is fixedly connected to one end of the second threaded sleeve. A second groove is provided in the support frame. A clamp is slidably connected inside the second groove. The clamp is fixedly connected to the inner wall of the second groove by a second spring. A plurality of evenly distributed protrusions are provided on the side of the clamp away from the second spring.

[0019] (15) By adopting the above technical solution, the support frame fixedly connected to one end of the second screw sleeve will move synchronously with the movement of the second screw sleeve. A second slide groove is provided in the support frame, and the clamping plate is slidably connected inside the second slide groove. When the support frame moves, the clamping plate will move in the second slide groove, and its movement direction is consistent with the movement direction of the support frame. The clamping plate and the inner wall of the second slide groove are fixedly connected by a second spring. In the initial state, the second spring is in a certain natural state. When the clamping plate moves with the support frame to contact the copper-clad laminate, if there is unevenness on the surface of the copper-clad laminate, the clamping plate will slide relative to the copper-clad laminate under the external force applied by the copper-clad laminate. At this time, the second spring will deform accordingly, thereby playing a buffering role, avoiding the transmission of excessive impact force to the entire clamping mechanism due to the unevenness of the copper-clad laminate surface, protecting the mechanism components and ensuring the stability of clamping. After the clamping operation is completed, when it is necessary to release the copper-clad laminate, the second screw sleeve drives the support frame to move in the opposite direction, and the second spring... The spring utilizes its stored elastic potential energy to return the clamping plate to its initial relative position within the second slide groove, preparing it for the next clamping operation. When the clamping plate contacts the copper-clad laminate during movement and performs a clamping operation, the protrusions embed into the surface of the copper-clad laminate. Within the limits of the copper-clad laminate material, this prevents excessive damage to the copper-clad laminate, thereby increasing the friction between the clamping plate and the copper-clad laminate, further enhancing the clamping firmness, and better fixing the copper-clad laminate in the required position. This ensures that the copper-clad laminate will not shift during subsequent processes such as hydraulic mechanisms performing forming operations on the copper-clad laminate.

[0020] (16) Further, the top and bottom ends of the second threaded sleeve are provided with limit rods, and the two limit rods are fixedly connected to the support frame. The fixed seat is provided with a third sliding groove for sliding connection of the limit rods.

[0021] (17) By adopting the above technical solution, on the one hand, the setting of the limiting rod and the third slide groove further limits the movement direction of the support frame, so that it can only move along the direction determined by the third slide groove, that is, it is consistent with the axial movement direction of the second screw sleeve, thereby ensuring the accuracy and stability of the movement of the support frame and preventing it from deviating or shaking during the movement; on the other hand, during the entire clamping operation, for example, when the second screw sleeve moves to the limit position, such as the limit state of clamping or loosening the copper-clad laminate, the limiting rod will contact the two ends of the third slide groove to play a limiting role, avoiding excessive movement of the second screw sleeve that could damage the component or affect the clamping effect. For example, when clamping the copper-clad laminate, it prevents the clamping plate from deforming or other components from being subjected to excessive force due to excessive clamping; when loosening the copper-clad laminate, it prevents the second screw sleeve from retracting excessively and leaving the normal working range.

[0022] (18) Compared with the prior art, the present invention has the following beneficial effects:

[0023] (19) The present invention provides a high-toughness copper clad laminate forming device. By setting a cooperative structure of a first motor, a first threaded rod and a first threaded sleeve, it can accurately control the distance between the hydraulic mechanism and the copper clad laminate material to be processed, thereby achieving precise adjustment of the forming pressure operation position. This precise position control helps to apply pressure evenly during the forming process of copper clad laminates of different thicknesses and specifications, improves the dimensional accuracy and flatness of the formed copper clad laminate, effectively reduces product defects caused by uneven pressure, and improves the overall quality and pass rate of the product.

[0024] (20) The present invention provides a high-toughness copper-clad laminate forming device. The coordinated action of the movable plate, sliding mechanism, pull rope and first spring in the device can not only ensure the stability of the entire device structure and the controllability of the action during the movement of the first screw sleeve, but also play a role in buffering and auxiliary support when the hydraulic mechanism applies pressure to form the copper-clad laminate. When the hydraulic mechanism applies a large pressure, the angle change of the movable plate will transmit the force to the first spring through the pull rope. The elastic deformation of the first spring can absorb part of the impact force, avoid damage to the copper-clad laminate caused by excessive instantaneous pressure, and also help to extend the service life of each mechanical component in the device, reduce equipment maintenance costs, and improve the safety and reliability of the production process.

[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0031] To prevent problems such as poor copper clad laminate (CCL) forming quality and low production efficiency caused by defects in the structure and function of traditional CCL forming equipment, and to improve the accuracy, stability, and production efficiency of CCL forming, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a high-toughness copper-clad laminate forming device includes a housing 1. A bracket 2 is welded to the top of the housing 1. A first motor 3 is fixedly installed at the middle of the top of the bracket 2. The output shaft of the first motor 3 passes through the bracket 2 and is fixedly connected to a first threaded rod 4. A first threaded sleeve 5 is movably passed through the top of the housing 1. The first threaded sleeve 5 is threadedly connected to the first threaded rod 4. A support plate 16 is fixedly connected to the bottom end of the first threaded sleeve 5. A hydraulic mechanism is provided below the support plate 16. Two symmetrical clamping mechanisms 19 are provided on the inner wall of the bottom end of the housing 1 and diagonally below the hydraulic mechanism.

[0032] The first threaded sleeve 5 has movable plates 6 hinged to both sides of its bottom. The top inner wall of the housing 1 is provided with two sliding mechanisms 7. The side of the movable plate 6 away from the hinge is movably connected to the sliding mechanism 7. The side of the movable plate 6 near the first threaded sleeve 5 is provided with a pull rope 11. The end of the pull rope 11 away from the movable plate 6 is fixedly installed with a first spring 12. The lower part of the first threaded sleeve 5 is provided with a guide hole 13. The first spring 12 is movably disposed in the guide hole 13. The side of the movable plate 6 near the first threaded sleeve 5 is provided with a fixing head 14. The fixing head 14 is fixedly connected to the movable plate 6, and one end of the pull rope 11 is fixedly connected to the fixing head 14. The bottom of the guide hole 13 is fixedly installed with a winding seat 15, and the pull rope 11 is movably wound on the winding seat 15.

[0033] The sliding mechanism 7 includes a slide rail 8, which is disposed on the inner wall of the top of the housing 1 and is integrally formed with the housing 1. The slide rail 8 has a T-shaped cross section. A slider 9 is slidably sleeved on the outside of the slide rail 8. The slider 9 is hinged to the movable plate 6. Limiting blocks 10 are provided at both ends of the slide rail 8, and the limiting blocks 10 are integrally formed with the slide rail 8.

[0034] In use, when the first motor 3 is started, its output shaft drives the first threaded rod 4 to rotate. Since the first threaded sleeve 5 is threadedly connected to the first threaded rod 4, the rotation of the first threaded rod 4 will cause the first threaded sleeve 5 to move upward or downward along its axis. During the downward movement of the first threaded sleeve 5, the support plate 16 fixedly connected to its bottom end will also rise or fall synchronously. The hydraulic mechanism set below the support plate 16 will also gradually move away from or closer to the location of the copper-clad laminate material to be processed inside the housing 1 as the support plate 16 moves upward or downward, so as to perform related forming pressure operations, etc. When the first threaded sleeve 5 moves upward, the movable plates 6 hinged on both sides of its bottom will change angle as the first threaded sleeve 5 moves upward. This is because the side of the movable plate 6 away from the hinge is movably connected to the sliding mechanism 7 set on the inner wall of the top of the housing 1. For the sliding mechanism 7, its slide rail 8 is fixed. On the inner wall of the top of the housing 1, the slider 9 is sleeved on the outside of the slide rail 8 and hinged to the movable plate 6. When the first screw sleeve 5 moves down and drives the movable plate 6 to move, the movable plate 6 will pull the slider 9 hinged to it to slide on the slide rail 8. The limit blocks 10 at both ends of the slide rail 8 can prevent the slider 9 from sliding out of the slide rail 8, ensuring the stability and controllability of the movable plate 6. A pull rope 11 is provided on the side of the movable plate 6 near the first screw sleeve 5. One end of the pull rope 11 is fixedly connected to the fixed head 14 fixed on the movable plate 6, and the other end is fixedly installed with the first spring 12. In the initial state, the first spring 12 is in a naturally extended state, and the pull rope 11 is also in a relatively relaxed state. When the movable plate 6 changes angle as the first screw sleeve 5 moves up, the movable plate 6 will pull the pull rope 11 through the fixed head 14. The pull rope 11 will pass around the winding seat 15 and pull the first spring 12, so that the first spring 12 is gradually stretched.

[0035] Throughout the molding process, when the hydraulic mechanism applies pressure to the copper-clad laminate for molding, the clamping mechanism 19 fixes the position of the copper-clad laminate to prevent unnecessary displacement of the copper-clad laminate when subjected to external forces such as pressure, thereby ensuring the accuracy and stability of the molding operation.

[0036] For example, such as Figure 1 As shown, the present invention also includes a hydraulic mechanism comprising a hydraulic press 17 fixedly installed at the middle of the bottom end of the support plate 16, and a pressure plate 18 fixedly installed at the output end of the hydraulic press 17.

[0037] When in use, start the hydraulic press 17. The output end of the hydraulic press 17 causes the pressure plate 18 to move downward to apply pressure to the copper-clad laminate.

[0038] For example, such as Figure 4As shown, the present invention also includes a clamping mechanism 19 comprising a second threaded rod 22 and a fixed seat 20. The second threaded rod 22 is rotatably connected to one side of the inner wall of the fixed seat 20 via a bearing. A second motor 23 is fixedly installed on one side of the fixed seat 20. The output shaft of the second motor 23 passes through the fixed seat 20 and is fixedly connected to the second threaded rod 22.

[0039] When in use, when the second motor 23 is started, its output shaft begins to rotate. Since the output shaft of the second motor 23 passes through the fixed base 20 and is fixedly connected to the second threaded rod 22, the rotational motion of the second motor 23 is directly transmitted to the second threaded rod 22, causing the second threaded rod 22 to rotate around its own axis.

[0040] For example, such as Figure 4 As shown, the present invention also includes a first sliding groove 21 provided inside the fixed base 20, a second threaded sleeve 24 movably passing through the side of the first sliding groove 21 away from the second motor 23, and the second threaded sleeve 24 being threadedly connected to the second threaded rod 22.

[0041] When the second threaded rod 22 rotates, based on the principle of thread transmission, the second threaded sleeve 24 will move axially on the second threaded rod 22. Because the second threaded sleeve 24 is restricted by the first sliding groove 21, it can only move along the direction defined by the first sliding groove 21, that is, along the direction parallel to the axis of the second threaded rod 22. This ensures the stability and directionality of the movement of the second threaded sleeve 24.

[0042] For example, such as Figure 4 As shown, the present invention also includes a support frame 25 fixedly connected to one end of the second threaded sleeve 24. A second sliding groove 26 is provided in the support frame 25. A clamping plate 27 is slidably connected inside the second sliding groove 26. The clamping plate 27 is fixedly connected to the inner wall of the second sliding groove 26 by a second spring 28. A plurality of evenly distributed protrusions 29 are provided on the side of the clamping plate 27 away from the second spring 28.

[0043] In use, the support frame 25, which is fixedly connected to one end of the second screw sleeve 24, moves synchronously with the movement of the second screw sleeve 24. The support frame 25 has a second sliding groove 26, and the clamping plate 27 is slidably connected inside the second sliding groove 26. When the support frame 25 moves, the clamping plate 27 moves in the second sliding groove 26, and its moving direction is the same as the moving direction of the support frame 25. The clamping plate 27 and the inner wall of the second sliding groove 26 are fixedly connected by the second spring 28. In the initial state, the second spring 28 is in a certain natural state. When the clamping plate 27 moves with the support frame 25 to contact the copper-clad laminate, if there are unevennesses on the surface of the copper-clad laminate, the clamping plate 27 will slide relative to the copper-clad laminate under the external force applied by the copper-clad laminate. At this time, the second spring 28 will deform accordingly, thereby playing a buffering role and preventing excessive impact force caused by the unevenness of the copper-clad laminate surface from being transmitted to the entire clamping mechanism, protecting the mechanism components and ensuring the stability of clamping. After the clamping operation is completed, when it is necessary to release the copper-clad laminate, the second screw sleeve 24 drives the support frame 25 to move in the opposite direction, the second spring 28... The second spring 28 utilizes its stored elastic potential energy to cause the clamping plate 27 to return to its initial relative position within the second slide groove 26, preparing for the next clamping operation. When the clamping plate 27 contacts the copper-clad laminate during movement and performs a clamping operation, the protrusion 29 will embed into the surface of the copper-clad laminate. If the copper-clad laminate material allows, it will not cause excessive damage to the copper-clad laminate, thereby increasing the friction between the clamping plate 27 and the copper-clad laminate, further enhancing the clamping firmness, and better fixing the copper-clad laminate in the required position, ensuring that the copper-clad laminate will not shift during subsequent processes such as forming operations performed by the hydraulic mechanism.

[0044] For example, such as Figure 4 As shown, the present invention also includes a limiting rod 31 provided at both the top and bottom of the second screw sleeve 24, both of the limiting rods 31 being fixedly connected to the support frame 25, and a third sliding groove 30 for sliding connection of the limiting rods 31 being provided on the fixed seat 20.

[0045] In use, on the one hand, the setting of the limiting rod 31 and the third slide groove 30 further limits the movement direction of the support frame 25, so that it can only move along the direction determined by the third slide groove 30, that is, it is consistent with the axial movement direction of the second screw sleeve 24, thereby ensuring the accuracy and stability of the movement of the support frame 25 and preventing it from deviating or shaking during the movement; on the other hand, during the entire clamping operation, for example, when the second screw sleeve 24 moves to the limit position, such as the limit state of clamping or loosening the copper-clad laminate, the limiting rod 31 will contact the two ends of the third slide groove 30 to play a limiting role, preventing the second screw sleeve 24 from moving excessively and causing damage to the components or affecting the clamping effect. For example, when clamping the copper-clad laminate, it prevents the clamping plate 27 from deforming or other components from being subjected to excessive force due to excessive clamping; when loosening the copper-clad laminate, it prevents the second screw sleeve 24 from retracting excessively and going out of the normal working range.

[0046] It should be noted that this utility model is a high-toughness copper-clad laminate forming device. When the first motor 3 is started, its output shaft drives the first threaded rod 4 to rotate. Since the first threaded sleeve 5 is threadedly connected to the first threaded rod 4, the first threaded sleeve 5 will move upwards or downwards along its axial direction. When the first threaded sleeve 5 moves downwards, the support plate 16 fixedly connected to its bottom end moves downwards synchronously. The hydraulic mechanism 17 and pressure plate 18 located below the support plate 16 will also gradually approach the location of the copper-clad laminate material to be processed inside the housing 1 as the support plate 16 moves downwards, so as to facilitate subsequent forming pressure operations. When the first threaded sleeve 5 moves upwards, the process is reversed. When the first threaded sleeve 5 moves upwards, its… The movable plate 6, hinged on both sides at the bottom, changes angle as the first screw sleeve 5 moves upward. This is because the side of the movable plate 6 away from the hinge is movably connected to a sliding mechanism 7 located on the inner wall of the top of the housing 1. Specifically, the slider 9 is sleeved outside the slide rail 8 and hinged to the movable plate 6. When the first screw sleeve 5 moves upward, causing the movable plate 6 to move, the movable plate 6 pulls the slider 9, which is hinged to it, to slide on the slide rail 8. The limiting blocks 10 at both ends of the slide rail 8 prevent the slider 9 from sliding off the slide rail 8. At the same time, a pull rope 11 is provided on the side of the movable plate 6 near the first screw sleeve 5. One end of the pull rope 11 is fixedly connected to the fixing head 14 fixed on the movable plate 6, and the other end is fixedly installed with a first spring 12. When the movable plate 6 changes angle as the first screw sleeve 5 moves upward, the movable plate 6 pulls the pull rope 11 through the fixing head 14. The pull rope 11 passes around the winding seat 15 and pulls the first spring 12, causing the first spring 12 to be gradually stretched.

[0047] When the second motor 23 in the clamping mechanism 19 is activated, its output shaft begins to rotate. Since the output shaft of the second motor 23 passes through the fixed seat 20 and is fixedly connected to the second threaded rod 22, the rotational motion of the second motor 23 is directly transmitted to the second threaded rod 22, causing the second threaded rod 22 to rotate around its own axis. Based on the principle of threaded transmission, when the second threaded rod 22 rotates, the second threaded sleeve 24, which is threadedly connected to the second threaded rod 22, will move axially on the second threaded rod 22. Because the second threaded sleeve 24 is restricted by the first sliding groove 21, it can only move along the direction defined by the first sliding groove 21, that is, along the direction parallel to the axial direction of the second threaded rod 22. The support frame 25, which is fixedly connected to one end of the second threaded sleeve 24, will move synchronously with the movement of the second threaded sleeve 24. The support frame 25 has an opening inside. There is a second slide groove 26, and the clamping plate 27 is slidably connected inside the second slide groove 26. When the support frame 25 moves, the clamping plate 27 will move in the second slide groove 26, and its movement direction is the same as the movement direction of the support frame 25. When the clamping plate 27 moves with the support frame 25 to contact the copper-clad laminate, if there is unevenness or other issues on the surface of the copper-clad laminate, the clamping plate 27 will slide relative to the copper-clad laminate in the second slide groove 26 due to the external force applied by the copper-clad laminate. At this time, the second spring 28 will deform accordingly, playing a buffering role, and the protrusion 29 will be embedded in the surface of the copper-clad laminate. If the copper-clad laminate material allows, it will not cause excessive damage to the copper-clad laminate, increase the friction between the clamping plate 27 and the copper-clad laminate, further enhance the clamping firmness, fix the copper-clad laminate in the required position, and prevent the copper-clad laminate from shifting in subsequent molding operations.

[0048] Start the hydraulic press 17. The output end of the hydraulic press 17 moves the pressure plate 18 downward to apply pressure to the copper-clad laminate for forming. During this process, since the clamping mechanism 19 has fixed the copper-clad laminate, the copper-clad laminate will not undergo unnecessary displacement, thereby ensuring the accuracy and stability of the forming operation.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
