Description

[0002] The laminating device for circuit board processing is the core equipment for the multi-layer manufacturing of circuit boards. By precisely controlling temperature, pressure and holding time, the copper-clad board, prepreg and other multi-layer substrates after pretreatment are tightly pressed together. During the process, the resin melts, flows, fills the gaps and solidifies to form a whole, which not only ensures the interlayer bonding strength and dimensional stability, but also avoids defects such as air bubbles and delamination, laying a foundation for subsequent drilling, etching and other processes of circuit boards, and is widely used in batch production of rigid PCB, flexible circuit board and rigid-flexible combined board.

[0003] The patent with patent number CN117320331B discloses a laminating device for thick copper printed circuit board. When the device is working, the first rack is located on the upper and lower sides of the first gear, so when the driving mechanism works, the driving mechanism can make the two lower pressing boards alternately located on the lower side of the upper pressing board through the cooperation of the telescopic mechanism and the guide groove. Then, the device can be moved without manual operation when working, and the feeding of the lower pressing board can be completed at the same time. At the same time, the continuous work of the device can be completed during the feeding process, making the device more convenient when working and improving the working efficiency of the device.

[0004] However, when the above-mentioned device is in use, the laminating device can only continuously feed and press two lower pressing boards, which results in limited batch size for single pressing and makes it difficult to meet the batch production demand of large-scale thick copper printed circuit boards, limiting the capacity improvement.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0034] Please refer to Figures 1-10 The present application is a kind of laminated device for circuit board processing, including workbench 1, workbench 1 is connected with support 11,

[0035] The workbench 1 is provided with a conveying assembly 2, the conveying assembly 2 comprises a bearing disc 21 connected with a plurality of mounting seats 22, the support 11 is provided with a pressing device 3, the bearing disc 21 is provided with a rotating assembly 4, the support 11 is provided with a positioning assembly 5 and a transmission assembly 6, the positioning assembly 5 comprises a positioning spring 51, the transmission assembly 6 is provided with a locking assembly 7, and the support 11 is provided with an unlocking assembly 8; when the pressing device 3 is pressed downward, the positioning assembly 5 is driven by the transmission assembly 6 to move to the direction close to the mounting seat 22, so as to clamp the mounting seat 22 loaded with the circuit board, and meanwhile the locking assembly 7 locks the clamping state of the positioning assembly 5, so as to ensure the position stability of the mounting seat 22 in the pressing process; after the pressing operation is completed, the transmission assembly 6 is driven by the pressing device 3 to reset upward, and the positioning assembly 5 is synchronously driven by the locking assembly 7 to separate from the mounting seat 22 which has completed the pressing; in this process, the bearing disc 21 is driven by the rotating assembly 4 driven by the pressing device 3 to rotate, so that the next mounting seat 22 to be pressed is accurately rotated to the position directly below the pressing device 3, and when the transmission assembly 6 moves upward, the unlocking assembly 8 is triggered to act, so as to release the locking of the positioning assembly 5 by the locking assembly 7, at this time, the positioning assembly 5 is quickly positioned to the mounting seat 22 to be pressed below the pressing device 3 under the elastic resetting action of the positioning spring 51, and then the pressing device 3 starts the next round of lamination operation; the device drives the plurality of mounting seats 22 on the bearing disc 21 to circularly switch to the pressing station through the rotating assembly 4, solves the technical problems of small processing batch quantity and insufficient production capacity of the existing equipment, and significantly improves the efficiency and batch production capacity of the circuit board lamination processing.

[0036] Please refer to Figures 1-2 As shown in the figure, the bearing disc 21 is rotationally connected with the workbench 1, and the plurality of mounting seats 22 are arranged in a ring array on the top wall of the bearing disc 21; during operation, the bearing disc 21 is driven by the rotating assembly 4 to rotate around the workbench 1, and the ring array of the mounting seats 22 are sequentially moved to the position directly below the pressing device 3, and cooperate with the positioning of the positioning assembly 5 and the fixing of the locking assembly 7, so that the pressing device 3 can continuously complete the pressing operation on the circuit boards in the mounting seats 22, and the processing efficiency and equipment production capacity are improved by increasing the processable quantity of a single batch.

[0037] Please refer to Figures 1-3As shown, the pressing device 3 includes an electric push rod 31 fixedly connected to the bracket 11. The output end of the electric push rod 31 is fixedly connected to a pressing plate 32, and the pressing plate 32 is fixedly connected to the transmission assembly 6. During operation, the electric push rod 31 extends and retracts to drive the pressing plate 32 to move up and down: when pressing down, the pressing plate 32 applies uniform pressure to the circuit board in the mounting base 22 to complete the lamination, and at the same time, the transmission assembly 6 triggers the positioning assembly 5 to clamp and the locking assembly 7 to fix it; when moving up, it drives the transmission assembly 6 to reset, providing space for the positioning assembly 5 to disengage and the bearing plate 21 to rotate and switch the mounting base 22. It achieves precise control and stable output of the pressing action through electric drive, laying the foundation for continuous pressing operation of the equipment and improving production capacity.

[0038] Please see Figures 1-4 As shown, the rotating assembly 4 includes a rotating shaft 41 rotatably connected to the bearing plate 21 via a one-way bearing. A cam groove 43 is provided on the side wall of the rotating shaft 41. A sliding sleeve 42 is fixedly connected to the pressing plate 32 via a connecting rod. A slider 44 is fixedly connected to the inner wall of the sliding sleeve 42 and is slidably connected in the cam groove 43. During operation, when the pressing plate 32 moves upward with the electric push rod 31, the sliding sleeve 42 moves upward synchronously via the connecting rod. The slider 44 slides along the cam groove 43 and drives the rotating shaft 41 to rotate unidirectionally, thereby driving the bearing plate 21 to rotate to switch the next mounting seat 22 to be pressed. When the pressing plate 32 is pressed down, the slider 44 slides in the opposite direction along the cam groove 43. The one-way bearing restricts the rotating shaft 41 from reversing, ensuring that the bearing plate 21 remains in a positioned state. This structure realizes the automatic intermittent rotation of the bearing plate 21 through the up and down movement of the linkage pressing device 3, without the need for additional driving components. While simplifying the equipment structure, it ensures the accuracy and continuity of the mounting seat 22 switching, providing power support for the efficient and continuous pressing operation of the equipment.

[0039] Please see Figures 1-4As shown, the cam groove 43 includes a positioning section 431, a flipping section 432, and a pressing section 433. The upper and lower ends of the flipping section 432 are connected to the positioning section 431 and the pressing section 433, respectively. The extension directions of the positioning section 431 and the pressing section 433 are parallel to the moving direction of the pressing plate 32. The flipping section 432 is spiral in shape. During operation, when the pressing plate 32 is pressed down for lamination, the slider 44 moves straight down along the pressing section 433. Because the direction of the pressing section 433 is parallel to the moving direction of the pressing plate 32, the rotating shaft 41 does not rotate, and the bearing plate 21 remains stably positioned to ensure accurate pressing. After pressing is completed, the pressing plate 32 moves up, and the slider 44 first moves straight up along the pressing section 433 to leave the pressing area, and then enters the spiral flipping section. When the slider 44 slides along the spiral trajectory of the transition section 432, it drives the rotating shaft 41 to rotate in one direction, which drives the bearing plate 21 to rotate synchronously through the one-way bearing, realizing the switching of the mounting seat 22. When the slider 44 slides into the positioning section 431, it moves straight up along the positioning section 431 parallel to the moving direction of the pressing plate 32, the rotating shaft 41 stops rotating, and the bearing plate 21 is precisely positioned, providing a stable reference for the positioning and pressing operation of the next mounting seat 22. This segmented slide design, through the trajectory change of the slider 44, accurately converts the up and down movement of the pressing plate 32 into the intermittent rotation and positioning of the bearing plate 21, which not only ensures the stability during pressing, but also realizes the automation and precision of the switching of the mounting seat 22. It is a key structure for the continuous and efficient operation of the equipment.

[0040] Please see Figures 1-3 and Figures 5-7As shown, the positioning component 5 includes a positioning gear 52 rotatably connected to the bracket 11 and two positioning racks 53 slidably connected to the bracket 11. The two sides of the positioning gear 52 mesh with the two positioning racks 53 respectively. The two positioning racks 53 are fixedly connected to two U-shaped clamps 54 via connecting rods. During operation, the positioning spring 51 drives the positioning gear 52 to rotate. Through the meshing of the positioning gear 52 with the two racks, the two positioning racks 53 slide synchronously in opposite directions, causing the two U-shaped clamps 54 to approach each other and clamp the mounting base 22, achieving precise positioning before the circuit board is pressed. After pressing, the transmission component 6 drives the positioning gear 52 to reset via the locking component 7, and the two U-shaped clamps 54 separate from the mounting base 22, becoming a support plate. 21. Rotate to switch positions to leave space; after the bearing plate 21 rotates, the pressing position aligns with the next mounting seat 22; the transmission component 6 continues to move upward, which will trigger the unlocking component 8 to release the locking component 7. The positioning gear 52 rotates on the next mounting seat 22 under the action of the positioning spring 51, and drives the two positioning racks 53 to slide in opposite directions synchronously, so that the two U-shaped clamps 54 approach each other and clamp the mounting seat 22, realizing accurate positioning before the circuit board is pressed. This structure ensures that the two clamps move in opposite directions synchronously through the meshing transmission of the gear and rack, which not only ensures the accuracy of the positioning of the mounting seat 22 and the stability of the clamping, but also can quickly respond to the action rhythm of the pressing device 3, providing a reliable positioning guarantee for the continuous and efficient pressing operation of the equipment.

[0041] Please see Figures 1-3 and Figures 5-7As shown, a drive rack 55 is slidably connected inside the bracket 11, and a transmission gear 56 is rotatably connected to it. A positioning spring 51 is located at the bottom end of the drive rack 55. The transmission gear 56 meshes with the drive rack 55, and the transmission gear 56 is connected to the positioning gear 52. During operation, the positioning spring 51 releases its elastic force, causing the drive rack 55 to slide along the bracket 11. Through meshing, it drives the transmission gear 56 to rotate, which in turn drives the positioning gear 52 to move the two positioning racks 53, thereby clamping the two U-shaped clamps 54 onto the mounting base 22. After pressing, the transmission assembly 6 drives the drive rack 55 to slide in the opposite direction and stretches the positioning spring 51 through the locking assembly 7. The transmission gear 56 rotates in the opposite direction with the drive rack 55, and the traction positioning gear 52 resets, causing the two positioning racks 53 to move the two U-shaped clamps 54 away from the mounting base. The mounting base 22 provides space for the rotating switching position of the bearing plate 21. After the bearing plate 21 rotates, the pressing position aligns with the next mounting base 22. The transmission component 6 continues to move upward, triggering the unlocking component 8 to release the locking component 7. The positioning gear 52 rotates on the next mounting base 22 under the action of the positioning spring 51, and drives the two positioning racks 53 to slide synchronously in opposite directions, so that the two U-shaped clamps 54 approach each other and clamp the mounting base 22, achieving precise positioning before the circuit board is pressed. This structure achieves precise power transmission and synchronous action of the positioning component 5 through the meshing transmission of the gear and rack and the elastic energy storage of the positioning spring 51. It not only ensures the stability of the positioning and clamping of the mounting base 22, but also quickly responds to the rhythm of the equipment operation, providing reliable power transmission for the cyclic action of the positioning component 5 and the continuous pressing operation of the equipment.

[0042] Please see Figures 1-3 and Figures 5-8As shown, the transmission assembly 6 includes a U-shaped frame 61 slidably connected to the bracket 11. The U-shaped frame 61 is fixedly connected to the pressing plate 32. A push block 62 is slidably connected to the inner wall of the U-shaped frame 61. A compression spring 63 is provided between the push block 62 and the top wall of the U-shaped frame 61. The push block 62 is positioned corresponding to the active rack 55 and is used to push the push block 62 through the compression spring 63, so that the push block 62 and the upper end of the active rack 55 remain in close contact. During operation, when the pressing device 3 presses down, the pressing plate 32 will drive the U-shaped frame. Simultaneously, push block 61 moves downward, and push block 62 moves downward and contacts drive rack 55. While compressing spring 63 to buffer the pressure, push block 62 presses drive rack 55 to move downward. Drive rack 55 to drive two U-shaped clamps 54 to clamp mounting base 22. At the same time, locking component 7 on transmission assembly 6 locks drive rack 55. After pressing, pressing device 3 moves upward to reset U-shaped frame 61. U-shaped frame 61 drives drive rack 55 upward through locking component 7, and drives transmission gear 56 to rotate through meshing. The movement of the U-shaped clamping plate 54, driven by the positioning gear 52, causes the two positioning racks 53 to move, thus detaching the two U-shaped clamps 54 from the mounting base 22. This creates space for the rotating and switching positions of the bearing plate 21. After the bearing plate 21 rotates via the rotating assembly 4, the pressing position aligns with the next mounting base 22. As the transmission assembly 6 continues to move upward, it triggers the unlocking assembly 8 to release the locking assembly 7. Under the action of the positioning spring 51, the positioning gear 52 rotates on the next mounting base 22 and drives the two positioning racks 53 to slide synchronously in opposite directions, causing the two U-shaped clamps 54 to approach each other and clamp the mounting base 22, achieving precise positioning before the circuit board is pressed. This structure, through the linkage between the U-shaped frame 61 and the pressing device 3, combined with the positioning of the compression spring 63, the locking of the locking assembly 7, and the release of the unlocking assembly 8, achieves precise driving and state maintenance of the active rack 55. This ensures the stability of positioning during pressing and also achieves automated reset and switching of the positioning assembly 5 through mechanical linkage, providing reliable transmission for the pressing operation of the equipment.

[0043] Please see Figures 8-10As shown, the locking assembly 7 includes a locking block 71 that is slidably connected to the inner wall of the U-shaped frame 61. A locking spring 72 is provided between the locking block 71 and the inner wall of the U-shaped frame 61. A locking groove 73 is provided on the side wall of the drive rack 55, and the locking groove 73 corresponds to the locking block 71. The bottom end of the locking block 71 is wedge-shaped. During operation, when the pressing device 3 presses down and moves the U-shaped frame 61 downward, and the push block 62 pushes the drive rack 55 downward to the clamping position, the wedge-shaped surface at the bottom end of the locking block 71 will first contact the top wall of the drive rack 55. Through the guiding action of the wedge-shaped surface, the locking block 71 is pushed to compress the locking spring 72 and move towards the U-shaped frame 61. The inner wall slides until the locking block 71 corresponds to the locking groove 73. Under the elastic force of the locking spring 72, the locking block 71 is engaged in the locking groove 73, locking the position of the active rack 55. When the pressing is completed and the U-shaped frame 61 moves the active rack 55 upward with the pressing device 3 to the position to be unlocked, the unlocking component 8 contacts the locking block 71. The unlocking component 8 pushes the locking block 71 to compress the locking spring 72 and slides it towards the inner wall of the U-shaped frame 61, causing the locking block 71 to disengage from the locking groove 73 and releasing the lock on the active rack 55. This provides conditions for the positioning component 5 to reset and clamp the next mounting seat 22 under the action of the positioning spring 51. This structure achieves precise control of the state of the active rack 55 through the spring-driven locking and the unlocking cooperation of the wedge surface. It not only ensures the positioning stability during pressing but also quickly responds to the rhythm of the equipment's operation to complete the unlocking. It is a key locking mechanism for continuous operation of the equipment.

[0044] Please see Figures 8-10 As shown, the unlocking component 8 includes an unlocking block 81 fixedly connected to the bracket 11, and a locking block 71 fixedly connected to a transmission block 82. Both ends of the unlocking block 81 along the sliding direction of the transmission component 6 are wedge-shaped. The pressing device 3 drives the U-shaped frame 61 to move, and the unlocking block 81 drives the transmission block 82 away from the active rack 55, thereby moving the locking block 71 out of the locking groove 73, thus releasing the position restriction of the active rack 55. During operation, after pressing is completed, the U-shaped frame 61 moves upward with the pressing device 3 to the unlocking position. The wedge-shaped ends of the transmission block 82 and the unlocking block 81 fit together. With the guiding effect of the wedge-shaped surface, the upward force of the U-shaped frame 61 is converted into the transmission block 82 moving towards the locking component 72. The lateral thrust in the direction of the transmission block 82 pushes the locking block 71 to compress the locking spring 72 and disengage from the locking groove 73, thus releasing the lock on the active rack 55. When the U-shaped frame 61 is pressed down and reset with the pressing device 3, the transmission block 82 contacts the other set of wedge ends of the unlocking block 81, and the transmission block 82 slides back and resets again through the wedge guide, preparing for the next unlocking action. This structure uses the bidirectional wedge surface guide transmission to realize the synchronous linkage between the unlocking action and the sliding of the transmission component 6. No additional driving components are required, which not only ensures the accuracy of the unlocking timing, but also simplifies the equipment structure, and provides a reliable unlocking guarantee for the cyclic clamping of the positioning component 5 and the continuous pressing operation of the equipment.
