Description

Technical Field

[0001] This invention relates to the field of automation technology, specifically to a PCB board pressing device with automatic loading and unloading functions. Background Technology

[0002] In the production of multilayer PCBs, lamination is a crucial process. Its function is to firmly bond the stacked inner core boards, prepregs, and outer copper foils into a single unit under high temperature and pressure. The quality of the lamination process directly determines the interlayer bonding strength, dimensional stability, and electrical reliability of the multilayer PCB. Currently, the traditional lamination equipment widely used in the industry typically consists of one or more presses and their associated feeding tables, heating plates, etc.

[0003] However, existing lamination equipment generally lacks automation, with loading and unloading operations relying primarily on manual labor or simple mechanical assistance. Specifically, operators manually move stacked PCB boxes from the feeding trolley to the hot plates of the press. After lamination, they manually remove the laminated boards and transfer them to the next process. This operating mode has several drawbacks: First, production efficiency is low; manual handling and positioning are slow and cannot match the high-efficiency operating cycle of the press, becoming a bottleneck restricting the overall production capacity. Second, labor costs are high and the workload is intense. The lamination process is typically in a high-temperature environment, and repetitive heavy handling poses a serious challenge to the operators' health. Furthermore, manual operation inevitably results in shaking, tilting, or placement deviations. These can lead to uneven pressure distribution during lamination, causing defects such as slippage, delamination, and warping; or, in severe cases, poor contact with the hot plates can cause uneven heating, seriously affecting the reliability of the boards.

[0004] Therefore, there is an urgent need for an automated lamination equipment that is highly integrated, stable in operation, precise in positioning, and adaptable to multi-specification production, so as to fundamentally improve the production efficiency, product quality, and intelligence level of the PCB lamination process.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example: Figures 1-6As shown, this invention provides a technical solution for a PCB board pressing device with automatic loading and unloading function. The device includes a cabinet 1, a conveyor belt 2 installed inside the cabinet 1, a pressing plate 3 installed above the conveyor belt 2, and the pressing plate 3 connected to a lifting assembly 4. The lifting assembly 4 is mounted on the cabinet 1. A loading rack 5 is provided at one end of the conveyor belt 2, and a transmission assembly 6 is installed at the bottom of the loading rack 5. A pushing component 7 is installed on the side of the other end of the conveyor belt 2, and a unloading rack 8 is installed on the pushing component 7 relative to the side of the conveyor belt 2. PCB boards are sequentially placed onto a carrier plate. On the 69, the carrier plate 69 is fixed by the support plate 6601 on the second transmission belt 66 on both sides. The transmission motor 62 at the bottom is turned on, which drives the first transmission belt 63 connected to the output end of the transmission motor 62 to rotate, thereby driving the drive shaft 65 to rotate. After the drive shaft 65 rotates, it will drive the third transmission belt 68 wound on its other end to rotate. The third transmission belt 68 drives the second driven shaft 67 to rotate, and finally drives the second transmission belt 66 to rotate. The transmission components 6 are symmetrically distributed on the loading rack 5, and the drive gear 6401 on the drive shaft 64 and the driven gear 6501 on the driven shaft 65 are connected by the drive gear 6401 on the drive shaft 64 and the driven gear 6501 on the driven shaft 65. The meshing of the drive shaft 64 and the driven shaft 65 enables the synchronous movement of the second transmission belts 66 on both sides of the loading rack 5, ensuring that the carrier plate 69 remains horizontally raised and lowered. When the carrier plate 69 moves to the same height as the opening 5101 on the baffle 5101, the linear push rod 5201 is activated to push out the push plate 5202. The push plate 5202 pushes the carrier plate 69 from the loading rack 5 along the opening 5101 and into the conveyor belt 2. Then, the belt 22 transports the carrier plate 69 containing the PCB board to the pressing device for pressing. The cooperation between the loading rack 5 and the transmission assembly 6 enables the carrier plate 69 to rotate, thereby achieving synchronous movement of the second transmission belts 66 on both sides of the loading rack 5, ensuring that the carrier plate 69 remains horizontally raised and lowered. The system can transfer PCB boards onto conveyor belt 2, which then transfers them to the pressing device, achieving automatic PCB board loading. After pressing, the PCB boards are removed from the pressing device via conveyor belt 2. Then, the carrier board 69 containing the PCB boards is pushed out of conveyor belt 2 by pusher 7 and moved into unloading rack 8, achieving automatic PCB board unloading. Therefore, by improving the PCB board pressing production line, not only can automatic PCB board loading and unloading operations be achieved, improving loading and unloading efficiency, but also the integrity of the PCB boards can be guaranteed, reducing losses.

[0020] A viewing window 11 is provided on the front side of the cabinet 1, and a fixing frame 12 is installed inside the cabinet 1. The conveyor belt 2 includes a conveyor frame 21, a belt 22 wound around the conveyor frame 21, and conveyor shafts 23 located at both ends of the belt 22. Several infrared sensors 2101 are installed on the conveyor frame 21. A drive box 24 is installed at one end of the conveyor frame 21. A drive motor 2401 is installed in the drive box 24. The output end of the drive motor 2401 is connected to a coupling 2402. The coupling 2402 is connected to one of the conveyor shafts 23. The conveyor belt 2 is powered by the drive box 24 and driven. The motor 2401 is fixed vertically inside the drive box 24. The output shaft of the drive motor 2401 is connected to the coupling 2402, which transmits the power of the drive motor 2401 to the conveyor shaft 23 to realize the normal operation of the conveyor belt 2. Under the transmission of the conveyor belt 2, the carrier plate 69 moves to the bottom of the pressing plate 3. Driven by the lifting motor 41, the pressing plate 3 is moved down to complete the pressing work. After pressing, the thickness of the pressed PCB board can be detected by the infrared sensor 2101 installed on the conveyor frame 21 to check whether the PCB board meets the requirements.

[0021] The pressing plate 3 includes a movable frame 31, a heating plate 32 installed inside the movable frame 31, and an adjusting rod 33 installed on the movable frame 31. The output end of the adjusting rod 33 is connected to one side of the movable frame 31. The pressing device is equipped with multiple pressing plates 3, which can not only press the PCB board multiple times to ensure the pressing accuracy, but also press multiple PCB boards at the same time to improve the pressing efficiency. The size of the movable frame 31 can be adjusted by the adjusting rod 33 to adapt to the pressing of PCB boards of different sizes, which greatly improves the applicability of the pressing device. The heating plate 32 heats the PCB board during the pressing process, which can improve the pressing efficiency and reduce the damage to the PCB board during the pressing process.

[0022] The lifting assembly 4 is installed on the fixed frame 12. The lifting assembly 4 includes a lifting motor 41. The output end of the lifting motor 41 is connected to the side of the movable frame 31. The other parallel side of the movable frame 31 is also connected by the lifting motor 41. A limit frame 42 is installed on the top of the movable frame 31. A limit rod 4201 is fixedly installed on the limit frame 42. The limit rod 4201 is connected to the hot plate 32.

[0023] The feeding rack 5 includes four vertically placed support rods 51. A baffle 5101 is installed on the inner side of two adjacent support rods 51. An opening 5102 is symmetrically opened on the baffle 5101. A crossbar 52 is installed between the remaining two support rods 51. A linear push rod 5201 is installed on the outer side of the crossbar 52. The linear push rod 5201 is connected to the push plate 5202. The crossbar 52 and the opening 5102 are at the same horizontal height.

[0024] The transmission assembly 6 includes a base 61 fixed to the bottom of the loading rack 5. A transmission motor 62 is mounted on the bottom of the base 61. The output end of the transmission motor 62 is connected to the drive shaft 64 via a first transmission belt 63. A drive gear 6401 is mounted on the drive shaft 64, which is fixed inside the base 61. A driven shaft 65 is mounted on one side of the drive shaft 64, and a driven gear 6501 is mounted on the driven shaft 65. A second transmission belt 66 is mounted between two opposing support rods 51. A second driven shaft 67 is mounted at both ends of the second transmission belt 66. One end of the drive shaft 64 is connected to the lower second driven shaft 67 via a third transmission belt 68. Several support plates 68 are evenly spaced on the second transmission belt 66, and a carrier plate 69 is placed on the support plate 68. When the transmission motor 62 at the bottom is turned on, it drives the first transmission belt 63 connected to the output end of the transmission motor 62 to rotate, thereby driving the drive shaft 65 to rotate. The drive shaft 65 rotates, which in turn drives the third transmission belt 68 wound around its other end to rotate. The third transmission belt 68 drives the second driven shaft 67 to rotate, which in turn drives the second transmission belt 66 to rotate. The transmission components 6 are symmetrically distributed on the loading rack 5. Through the meshing of the drive gear 6401 on the drive shaft 64 and the driven gear 6501 on the driven shaft 65, the drive shaft 64 drives the driven shaft 65 to rotate, thereby achieving synchronous movement of the second transmission belts 66 on both sides of the loading rack 5. This ensures that the carrier plate 69 always remains horizontally raised and lowered. When the carrier plate 69 moves to the same height as the opening 5101 on the baffle 5101, the linear push rod 5201 is activated to push out the push plate 5202. The push plate 5202 pushes the carrier plate 69 out of the loading rack 5 along the opening 5101 and into the conveyor belt 2. Then, the carrier plate containing the PCB board is transported to the pressing device by the belt 22 to complete the pressing.

[0025] The pusher 7 includes a pusher plate 71, on the surface of which an optical sensor 72 is mounted. The pusher plate 71 is connected to a pusher motor 73. A second limit rod 74 is also mounted on the pusher plate 71 and is fixed by a limit block 75. The unloading rack 8 is provided with a platform 81, which is at the same height as the upper surface of the conveyor belt 2. The pusher plate 71 is driven by the pusher motor 73 and is limited by the second limit rods 74 mounted on both sides to ensure that the pusher plate 71 always moves in a straight line. The optical sensor 72 mounted on the surface of the pusher plate 71 can detect the position of the carrier plate 69. When the carrier plate 69 is transported to the front of the pusher plate 71, the pusher motor 73 starts and pushes the carrier plate 69 into the platform 81 to complete the unloading of the PCB board.

[0026] Working principle of the invention: The PCB boards are placed sequentially onto the carrier plate 69, which is fixed by the support plates 6601 on the second transmission belts 66 on both sides. The transmission motor 62 at the bottom is turned on, driving the first transmission belt 63 connected to the output end of the transmission motor 62 to rotate, which in turn drives the drive shaft 65 to rotate. The rotation of the drive shaft 65 then drives the third transmission belt 68 wound on its other end to rotate, which in turn drives the second driven shaft 67 to rotate, ultimately driving the rotation of the second transmission belt 66. The transmission components 6 are symmetrically distributed on the loading rack 5, and the drive shaft 64 is connected by the drive gear 6401. The meshing of the driven gear 6501 on the driven shaft 65 enables the drive shaft 64 to drive the driven shaft 65 to rotate, thereby achieving synchronous movement of the second transmission belts 66 on both sides of the loading rack 5, ensuring that the carrier plate 69 always remains horizontally raised and lowered. When the carrier plate 69 moves to the same height as the opening 5101 on the baffle 5101, the linear push rod 5201 is activated to push out the push plate 5202. The push plate 5202 pushes the carrier plate 69 out of the loading rack 5 along the opening 5101 and into the conveyor belt 2. Then, the carrier plate containing the PCB board is transported to the pressing device by the belt 22 to complete the pressing.

[0027] The conveyor belt 2 is powered by the drive box 24. The drive motor 2401 is fixed in the drive box 24 in the vertical direction. The output shaft of the drive motor 2401 is connected to the coupling 2402 to transmit the power of the drive motor 2401 to the conveyor shaft 23, so as to realize the normal operation of the conveyor belt 2.

[0028] Driven by the conveyor belt 2, the carrier plate 69 is moved into the pressing device, which contains two pressing plates 3. First, the carrier plate 69 is moved to a position below the pressing plate 3 near the inlet. Infrared sensors 2101 are installed on the conveyor frame 21 directly below both pressing plates 3. The infrared sensors 2101 monitor and assist in positioning the carrier plate 69, ensuring that it is directly below the pressing plate 3. Then, the pressing plate 3 is driven downward by the lifting motor 41. During the downward movement, the pressing plate 3 is limited by the limiting rod 4201 to ensure that the pressing plate 3 can always move vertically, so that the contact surface between the PCB board and the pressing plate 3 is completely adhered, preventing the pressing surface from tilting. At the same time, a heating plate 32 is installed on the pressing plate 3 to provide heat during the pressing process. Heating the PCB board makes it easier to complete the PCB board pressing and reduces the probability of PCB board damage. In addition to positioning the carrier board 69, the infrared sensor 2101 can also detect the thickness of the pressed PCB board. After pressing, the infrared sensor 2101 installed on the conveyor frame 21 can detect whether the thickness of the PCB board meets the requirements. If it does not meet the requirements, the conveyor belt 2 is started to move the carrier board 69 directly under the next pressing plate 3 for secondary pressing of the PCB board. In addition to secondary pressing of the PCB board, the setting of two pressing plates 3 can also improve the pressing efficiency for PCB boards with lower requirements. The two pressing plates 3 can work simultaneously to press multiple PCB boards at the same time, which greatly shortens the pressing time.

[0029] After the PCB board is pressed, the conveyor belt 2 restarts, removing the carrier plate 69 from the pressing device. An optical sensor 72 is installed on the push plate 71. When the carrier plate 69 moves to the front of the push plate 71 and completely blocks the optical sensor 72, the drive motor 73 starts working, driving the push plate 71 to move and push the carrier plate 69 out of the conveyor belt 2, so that it enters the loading table 81 of the unloading rack 8. The loading table 81 has a notch. As the carrier plates 69 are continuously pushed into the loading table 81, the previous carrier plate 69 will leave the loading table 81 through the notch, and the next carrier plate 69 will be pushed into the loading table 81, so that only one carrier plate 69 is always placed on the loading table 81. The PCB board that has completed the pressing process is removed from the pressing device by the conveyor belt 2. Then, the pusher 7 pushes the carrier plate 69 containing the PCB board out of the conveyor belt 2 and moves it into the unloading rack 8 to realize the automatic unloading of the PCB board.

[0030] The carrier plate 69 not only securely fixes the PCB board to prevent it from falling during transport, but also provides support for the PCB board during the pressing process, preventing the pressing plate 3 from damaging the conveyor belt 2 or the PCB board. After pressing, the pushing component 7 automatically detaches the PCB board from the conveyor belt 2. The entire process requires no manual intervention, further ensuring the automation of the PCB board during the pressing process.

[0031] The transmission component 6 automatically pushes the carrier board containing the PCB board placed on the loading rack 5 into the conveyor belt 2 of the pressing device. After being processed by the pressing device, the pressed PCB board is sent out by the conveyor belt 2. Then, the pusher 7 moves the PCB board out of the conveyor belt 2 and pushes it into the unloading rack 8, thus completing the automatic loading and unloading of the PCB board.

[0032] Multiple infrared sensors 2101 are installed on the conveyor belt. In addition to positioning the pressing plate, the infrared sensors 2101 can also monitor the pressing of the PCB board in real time. When the thickness of the pressed PCB board does not meet the standard, it can be detected in time to ensure the quality of the PCB board.

[0033] The size of the movable frame 31 can be changed by adjusting the rod 33 inside the pressing plate 3, thereby adapting to the pressing operation of PCB boards of different sizes and greatly improving the applicability of the pressing device.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
