[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0021] Embodiment 1, as Figure 1 and Figure 2As shown, a PCB board leveling device includes a workbench 1, an upper leveling component 2 is arranged at the upper end of the workbench 1, a fixing seat 11 is fixedly connected to the upper end of the workbench 1, a through groove 12 is opened at the upper end of the workbench 1, a loading component 3 is arranged at the right end of the workbench 1, a cleaning component 4 is arranged at the left end of the loading component 3, a heating component 5 is arranged at the lower end of the upper leveling component 2, and a lower leveling component 6 is arranged at the upper end of the workbench 1.

[0022] Therefore, this solution uses the loading component 3 and the cleaning component 4 to first clean the PCB board being loaded to prevent dust and impurities from affecting the processing quality. Then, the upper leveling component 2, the heating component 5 and the lower leveling component 6 are used to cooperate with each other so that when the upper leveling component 2 descends, the heating component 5 is driven to perform preliminary heating and pressing treatment on the PCB board to remove moisture and bubbles on the surface of the PCB board and improve the flatness and adhesion of the board surface. Then, the upper leveling component 2 and the lower leveling component 6 are used to press the upper and lower surfaces of the PCB board synchronously to perform all-round calibration on the PCB board to ensure that it reaches the required flatness in all directions, thereby achieving precise leveling of the PCB board.

[0023] Embodiment 2: Based on embodiment 1, this embodiment is to achieve the effect of simultaneous cleaning during the process of loading PCB boards.

[0024] For details, see Figure 9-11 The loading assembly 3 includes a fixed block 2 31 fixedly connected to the right side of the upper end of the workbench 1, a hydraulic device 2 32 is fixedly installed on the right end of the fixed block 2 31, a connecting seat 1 33 is fixedly connected to the output end of the hydraulic device 2 32, three connecting rods 34 are fixedly connected to the left end of the connecting seat 1 33, and the right ends of the three connecting rods 34 are commonly fixedly connected to a pushing plate 35.

[0025] Furthermore, the height of the pushing plate 35 is lower than the cleaning brushes 46, and five cleaning brushes 46 can pass through the process of pushing the PCB board material.

[0026] Then, the hydraulic device 2 32 is started to drive the connecting seat 1 33 , the connecting rod 34 and the pushing plate 35 to move to the left side, pushing the PCB board for loading. During the process, the PCB board will pass through multiple cleaning brushes 46 .

[0027] See also Fig.10 and Fig.11 The cleaning assembly 4 includes a support base 41 fixedly connected to the upper end of the workbench 1, a front side wall of the inner surface of the support base 41 is rotatably connected to a rotating shaft 1 42, an outer surface of the rotating shaft 1 42 is fixedly connected to a gear 1 43, and the inner surface of the support base 41 is rotatably connected to five rotating shafts 2 45, and the outer surface of the rotating shaft 2 45 close to the gear 1 43 and the rear end of the gear 1 43 are fixedly connected to a bevel gear transmission group 44.

[0028] The lower ends of the five rotating shafts 2 45 are fixedly connected with cleaning brushes 46, the upper ends of the five rotating shafts 2 45 are fixedly connected with gears 2 47, the outer surfaces of the five gears 2 47 are meshed with each other, the front end of the connecting seat 1 33 is fixedly connected with a rack 1 48, and the outer surface of the rack 1 48 is meshed with the gear 1 43.

[0029] Furthermore, the bevel gear transmission group 44 is composed of two bevel gears meshing with each other, so that when the gear 1 43 rotates, the rotating shaft 2 45 can be driven to rotate together, and the rotating shaft 2 45 close to the side of the gear 1 43 will drive the gear 2 47 to rotate when rotating, so that the five gears 2 47 are meshed with each other, thereby driving the cleaning brush 46 to rotate together. The cleaning brush 46 can clean the dust on the surface of the PCB board to prevent dust and impurities from affecting the subsequent processing quality.

[0030] Furthermore, when the connecting seat 1 33 is driven by the hydraulic device 2 32 to move to the left, the rack 1 48 will move together, so that the rack 1 48 and the gear 1 43 will mesh, driving the rotating shaft 1 42, the bevel gear transmission group 44 and the rotating shaft 2 45 to rotate. When the rotating shaft 2 45 rotates, it will drive the five gears 2 47 to mesh with each other, so that the five cleaning brushes 46 will rotate, and the dust on the surface of the PCB board will be cleaned when it passes by.

[0031] Therefore, in this solution, through the cooperation between the loading component 3 and the cleaning component 4, when the connecting seat 1 33 pushes the PCB board to be loaded, the engagement of the rack 1 48 and the gear 1 43 is used to drive the five rotating shafts 2 45, the cleaning brush 46 and the gear 2 47 to rotate synchronously, so as to clean the surface of the moving PCB board, effectively remove dust, oil and other impurities, and provide a clean surface for subsequent processing steps.

[0032] Embodiment 3: Based on Embodiments 1 and 2, this embodiment is for realizing precise leveling of the PCB board and improving the processing quality.

[0033] For details, see Figure 1-8 The upper leveling component 2 includes a hydraulic device 21 fixedly installed on the upper end of the fixed seat 11, the output end of the hydraulic device 21 is fixedly connected to a fixed block 22, the lower end of the fixed block 22 is fixedly connected to four springs 23, and the lower ends of the four springs 23 are commonly fixedly connected to an upper adjustment plate 24.

[0034] A protrusion 25 is fixedly connected to one side of the upper end of the fixing block 1 22 , a switch 26 is provided on one side of the lower end of the fixing seat 11 , the upper end of the protrusion 25 is movably connected to the switch 26 , and the switch 26 is electrically connected to the hydraulic device 2 32 .

[0035] Furthermore, the hydraulic device 21 belongs to the prior art, and can drive the fixed block 22 to rise and fall as a whole. The spring 23 can provide a buffer when the upper adjustment plate 24 squeezes the PCB board to avoid damage to the PCB board. Among them, the convex block 25 will contact with the switch 26 when it follows the fixed block 22 to rise to the top, and touch the switch 26. When the switch 26 is touched, it means that the processing of the PCB board is completed, and the hydraulic device 2 32 will be automatically turned on, so that the hydraulic device 2 32 pushes the next PCB board to be loaded, and the previous PCB board that has been processed is pushed away. Its working principle is: When the fixed block 22 touches the switch 26, the switch 26 will send a start signal to the control unit. This signal can be an electrical signal transmitted through wires, or a wireless signal transmitted through the air. After receiving the start signal, the control unit will immediately send an instruction to the hydraulic device 2 32 to start working.

[0036] After the hydraulic device 2 32 starts working, the hydraulic oil in the oil tank will be pumped out and transported to the hydraulic cylinder through the pipeline. The piston in the hydraulic cylinder starts to move under the push of the hydraulic oil, thereby completing the required work.

[0037] When the switch 26 is no longer touched, it sends a stop signal to the control unit. After receiving the stop signal, the control unit immediately sends an instruction to the hydraulic device 2 32 to stop working. At the same time, the control unit also adjusts the position of the control valve to prevent the hydraulic oil from continuing to flow.

[0038] As the hydraulic device 2 32 stops working, the piston in the hydraulic cylinder will also stop moving, and the hydraulic cylinder will slowly return to the initial position due to the action of the return spring or other mechanisms.

[0039] See also Figure 3 and Figure 5 The heating assembly 5 includes a fixed block 3 51 fixedly connected to the rear end of the fixed block 1 22, and the left and right sides of the upper end of the workbench 1 are fixedly connected to the limiting seats 52, the inner surfaces of the two limiting seats 52 are fixedly connected to the limiting rods 1 53, and the outer surfaces of the two limiting rods 1 53 are slidably connected to the limiting blocks 54, and the two limiting blocks 54 are fixedly connected to a sliding shaft 55 on one side close to each other.

[0040] Furthermore, the limit rod 53 and the limit block 54 can provide space for the structures such as the sliding shaft 55, the sliding seat 56 and the L-shaped slide groove 57 to move upward, which is convenient for loading the PCB board. The sliding shaft 55 can limit the sliding seat 56 so that it can slide stably left and right.

[0041] The outer surface of the sliding shaft 55 is slidably connected to two sliding seats 56, and the outer surfaces of the two sliding seats 56 are each provided with an L-shaped slide groove 57. The left and right sides of the fixed block three 51 are fixedly connected to connecting frames 58, and the lower ends of the two connecting frames 58 are rotatably connected to rollers 59. The outer surfaces of the two rollers 59 are slidably connected to the inner surfaces of the two L-shaped slide grooves 57. The lower sides of the front ends of the two sliding seats 56 are fixedly connected to connecting blocks 510, and the front ends of the two connecting blocks 510 are each installed with hot rollers 511.

[0042] Furthermore, the angle of the L-shaped slide 57 is an obtuse angle, and the heat roller 511 is an infrared heat roller in the prior art. The process of heating and leveling the PCB board using the infrared heat roller can not only effectively remove the internal stress of the PCB board, but also avoid physical damage to the PCB board. Its working principle is as follows: Through infrared radiation heating, infrared radiation sources such as metal heating tubes, carbon fiber heating elements or quartz lamps transfer heat energy to the surface of the PCB in the form of radiation. The wavelength and band of infrared radiation can be adjusted as needed. Generally, short-wave infrared is more suitable for PCB heating because short-wave infrared can be quickly absorbed by the surface material of the PCB, thereby accelerating the heating process; During the heating process, the infrared heat roller is usually equipped with a temperature sensor and a PID temperature control system. Temperature sensors such as thermocouples and infrared thermometers monitor the surface temperature of the PCB in real time. The PID control system accurately adjusts the power output of the heat roller according to the feedback signal to ensure that the temperature of the PCB is always kept within the set range during the heating process. This can effectively avoid damage caused by excessive temperature. During the production process of PCB boards, especially in the manufacturing process of multi-layer PCBs, internal stress is often generated due to different material layers and processing techniques. The existence of internal stress may cause the PCB board to warp or deform during use. By heating with an infrared hot roller, the temperature of the PCB board can be evenly increased, and the expansion speed of each part of the material can be consistent, thereby alleviating or eliminating the internal stress, thereby achieving leveling of the PCB board. Temperature uniformity and controllability are the key to achieving this goal.

[0043] Then, when the PCB board reaches the through groove 12, the fixed block 22 is started to drive the spring 23 to descend as a whole, so that the connecting frame 58 and the roller 59 will first drive the limit block 54, the sliding shaft 55, the sliding seat 56, and the L-shaped slide groove 57 to descend as a whole, so that they are in contact with the upper end of the workbench 1 and the hot roller 511 is in close contact with the PCB board. Then, when descending, the connecting frame 58 and the roller 59 will slide in the L-shaped slide groove 57. When the roller 59 slides in the inclined part of the L-shaped slide groove 57, the two sliding seats 56 will move in opposite directions at the same time, thereby driving the two hot rollers 511 to open to both sides at the same time. The hot rollers 511 move to both sides while being in close contact with the surface of the PCB board, and the PCB board is preliminarily heated and pressed. When the roller 59 slides in the vertical part of the L-shaped slide groove 57, the two hot rollers 511 are completely located on the left and right outer sides of the PCB board. At this time, the upper adjustment plate 24 will continue to move toward the PCB board.

[0044] See also Figure 6-8 The lower leveling assembly 6 includes a fixed block four 61 fixedly connected to one side of the front end of the fixed block one 22, the front end of the fixed block four 61 is fixedly connected to a rack two 62, the upper end of the workbench 1 is fixedly connected to a support block 63, the rear side of the support block 63 is rotatably connected to a gear three 64, the outer surface of the rack two 62 is meshed with the gear three 64, the side of the gear three 64 away from the rack two 62 is meshed with a rack three 65, and the outer surface of the rack three 65 is slidably connected to the workbench 1.

[0045] Furthermore, when the gear three 64 rotates, it drives the rack two 62 on the left and the rack three 65 on the right to rise and fall in opposite directions.

[0046] See also Figure 8 The lower end of the rear side of the rack three 65 is fixedly connected to the connecting seat two 66, the upper end of the connecting seat two 66 is fixedly connected to the lower adjustment plate 67, the outer surface of the lower adjustment plate 67 is slidably connected to the through groove 12, the lower end of the workbench 1 is fixedly connected to four fixing rods 68, the lower ends of the four fixing rods 68 are commonly fixedly connected to the base 69, the upper end of the base 69 is fixedly connected to two limiting rods two 610, the outer surface of the limiting rods two 610 is slidably connected to the connecting seat two 66.

[0047] Furthermore, the connecting seat 2 66 and the lower adjustment plate 67 can move upward from the lower side of the PCB board under the drive of the rack 3 65, drive the PCB board to be lifted, and level the upper and lower surfaces of the PCB board at the same time to ensure that it reaches the required flatness in all directions and reduce the processing error caused by the unevenness of the PCB board. The limit rod 2 610 can limit the connecting seat 2 66 and the rack 3 65, so that the lower adjustment plate 67 can move up and down stably.

[0048] Furthermore, when the roller 59 slides in the vertical part of the L-shaped slide groove 57, the rack 2 62 will contact and mesh with the gear 3 64 during the process of descending, so that the rack 3 65 is lifted, driving the connecting seat 2 66 and the lower adjustment plate 67 to move upward, and the PCB board is lifted, so that the PCB board is located between the lower adjustment plate 67 and the upper adjustment plate 24, and is leveled on the upper and lower surfaces to ensure that it reaches the required flatness in all directions; After the processing is completed, the hydraulic device 21 will drive the fixed block 22 to rise and separate it from the PCB board. Among them, the protrusion 25 will contact the switch 26 when it follows the fixed block 22 to rise to the top, and touch the switch 26. When the switch 26 is touched, it means that the processing of the PCB board is completed, and the hydraulic device 2 32 will be automatically turned on, so that the hydraulic device 2 32 pushes the next PCB board to be loaded, and pushes away the previous PCB board that has been processed, and then continues to level the PCB board.

[0049] Therefore, this solution cooperates with the heating component 5 and the lower leveling component 6 during the descending process of the fixed block 22, so that the hot roller 511 moves to both sides while closely contacting the surface of the PCB board, and performs preliminary heating and pressing treatment on the PCB board, which helps to remove moisture and bubbles on the surface of the PCB board and improve the flatness and adhesion of the board surface. Then, the lower leveling component 6 is used to drive the lower adjustment plate 67 to lift the PCB board, so that the PCB board is located between the lower adjustment plate 67 and the upper adjustment plate 24 for pressing and leveling, ensuring that the PCB board reaches the required flatness in all directions, eliminating the slight deformation or tilt that may occur in the PCB board during the processing, thereby improving the processing accuracy and consistency, and improving the product yield and quality.

[0050] It should be noted that the specific installation method of the hydraulic device 1 21, the switch 26, the hydraulic device 2 32 and the hot roller 511 used in the present invention, the circuit connection method and the control method are all conventional designs and will not be elaborated in detail in the present invention.
