Description

Technical Field

[0001] The present invention relates to the field of circuit board production, and more particularly, to a vertical printing auxiliary loading device. Background Art

[0002] Screen printing refers to using a screen as a printing plate base and making a screen printing plate with graphics and text through a photosensitive plate-making method. Screen printing consists of five major elements: a screen printing plate, a squeegee, ink, a printing table, and a substrate. Printing is carried out based on the basic principle that the ink can pass through the mesh holes in the graphic part of the screen printing plate, while the ink cannot pass through the mesh holes in the non-graphic part.

[0003] PCB, whose Chinese name is printed circuit board, also known as printed wiring board, is an important electronic component, a support for electronic components, and a carrier for the electrical interconnection of electronic components. Since it is made by electronic printing technology, it is called a "printed" circuit board.

[0004] Currently, for the multi-track feeding vertical printing machine of PCB, during manual loading, it is necessary to manually send the PCB board to the position where each feeding frame is located. When a feeding frame is far away from the operator, the operator needs to stretch their arm to the limit to load the material, which makes the operator prone to fatigue. At the same time, the body is prone to lean forward and fall into the machine, resulting in a large safety hazard. Moreover, when loading the material, the operator vertically sets the PCB board on the positioning mechanism. However, when the PCB board is vertically placed, it is prone to deformation under the influence of external forces, and there are also flexible circuit boards in the PCB board, resulting in poor use effects and being inconvenient for clamping and loading operations.

[0005] Therefore, we make improvements and propose a vertical printing auxiliary loading device. Summary of the Invention

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] In the solution of the present application:

[0024] 1. In order to solve the problem in the prior art that when the feeding frame is far away from the operator, the operator needs to stretch the arm to the limit to load the material, which is easy for the operator to get tired, and at the same time, the body is prone to lean forward and fall into the machine, resulting in a great safety hazard. The present application realizes the effect of safe loading through the vertically printed auxiliary loading mechanism and the PCB board clamping mechanism set. Since the operator's loading position is outside the machine, the operator's body does not need to reach into the machine for operation, avoiding the risk of being injured by the moving parts inside the machine. At the same time, the loading position is the optimal distance for the operator's arm to operate outside, and there is no need to stretch the arm excessively. Operators with different arm lengths are easy to operate, reducing the labor intensity and fatigue.

[0025] 2. In order to solve the problem in the prior art that when loading the material, the PCB board is prone to deformation under the influence of external forces when placed vertically, resulting in poor use effect and inconvenient clamping and loading operation. The present application improves the flatness effect of the vertically placed PCB board through the fixed auxiliary module and the pressing plate module set, and at the same time is convenient for clamping operation. The fixed auxiliary module can adsorb and fix the PCB board during the loading operation to avoid the situation of the PCB board moving or shifting during the subsequent loading process, ensuring the stability during the loading process. At the same time, when in use, the fixed auxiliary module can also clean the surface of the positioning substrate to avoid the attachment of dust and other impurities, thereby avoiding the situation of the PCB board warping when placed for loading. The pressing plate module can press the PCB board after it is placed for loading to ensure that it is in a flat state when the PCB board is in a vertical state, further avoiding the deformation of the PCB board, and at the same time enabling the device to be more suitable for flexible circuit boards, facilitating the clamping operation of the PCB board clamping mechanism on the PCB board, and increasing the applicability and use effect of the device.

[0026] 3. Through the set feeding module, the position adjustment and attitude adjustment of the PCB board are realized. When feeding the PCB board, the position of the PCB board can be adjusted by the feeding module to make it correspond to the position of the vertical printing auxiliary feeding mechanism, so as to facilitate the transfer of the PCB board. Moreover, before the position adjustment corresponds, the PCB board can be further away from the feeding area, further increasing the use safety of the device. At the same time, adjusting the attitude of the PCB board can also facilitate its transfer, and it is convenient for the PCB board clamping mechanism to clamp and fix it during transfer, increasing the use convenience of the device.

[0052] Please refer to Figure 3 , a vertical printing auxiliary feeding device, the PCB board clamping mechanism 5 of which includes four cylinder mounting plates 52. The four cylinder mounting plates 52 are respectively arranged on the clamping base and the Z-axis guide frame 13. A rotating shaft 53 and a clamping cylinder 51 are movably connected to each of the four cylinder mounting plates 52. The outer wall of the rotating shaft 53 and the output end of the clamping cylinder 51 on the same cylinder mounting plate 52 are both provided with the same pressure block mounting plate 54. A PCB board pressure block 55 is arranged on each of the four pressure block mounting plates 54. A PCB board body 4 is arranged among the four PCB board pressure blocks 55.

[0053] The effect of safe feeding is achieved through the provided vertical printing auxiliary feeding mechanism 1 and the PCB board clamping mechanism 5. Since the employee's feeding position is outside the machine, the employee's body does not need to reach into the machine for operation, avoiding the risk of injury to the body by the moving parts inside the machine. At the same time, it is the best distance for the employee's arm to operate outside the feeding position, and there is no need to overly extend the arm.

At this time, the air pump body 77 is started, and the control valves 76 on the air inlet pipe 79 and the connecting hose 74 are opened at the same time, so that the gas enters the inside of the air pump body 77 through the air inlet pipe 79 and the purification device 714, and is further conveyed to the inside of the cleaning air chamber 71 through the connecting hose 74 to spray the gas through the cleaning port 72, so as to clean the surface of the positioning substrate 610. After cleaning, the electric telescopic rod 73 drives the cleaning air chamber 71 to reset, and at the same time closes the control valves 76 on the connecting hose 74 and the air inlet pipe 79;

[0066] When the PCB board is placed, the PCB board is arranged on the positioning substrate 610 and is limited by the limiting roller 103. At this time, the air pump body 77 is started again, and the control valves 76 on the exhaust pipe 75 and the negative pressure pipe 78 are opened, so that the air pump body 77 discharges the gas inside the communication chamber 710 through the negative pressure pipe 78, and then makes the inside of the communication chamber 710 in a negative pressure state, and then makes the fixed suction cup 711 adsorb and fix the PCB board through the connecting pipe 713;

[0067] After the PCB board is fixed, start the drive motor 87. The drive motor 87 can drive the gear 86 to rotate. Since the drive gear 86 meshes with the transmission gear 85, the shaft rod 812 and the winding wheel 84 rotate, thereby winding the connection cable 83. Further, the connection cable 83 pulls the mounting frame member 810, and the telescopic spring rod 811 is compressed. When the mounting frame member 810 moves to the moving position, start the electric rod 89. The electric rod 89 drives the PCB board pressing plate 88 to descend to press the PCB board to ensure its flatness.

[0068] During loading, start the flipping motor 66. The flipping motor 66 drives the connecting roller member 65 and the positioning substrate 610 to rotate 90 degrees, so that the PCB board is in a vertical state. Then, drive the transverse lead screw 62 and the longitudinal lead screw 67 to operate through the transverse motor 68 and the longitudinal motor 69 to adjust the position of the movable base 64, so that the position of the PCB board corresponds to that of the vertical printing auxiliary loading mechanism 1 during loading to complete the loading positioning.

[0069] Confirm that the PCB board is positioned. The touch switch makes the vertical printing auxiliary loading mechanism 1 start to act, and the PCB board clamping mechanism 5 clamps the PCB board body 4. At this time, the drive motor 87 rotates in reverse, so that the telescopic spring rod 811 is restored. At the same time, the electric rod 89 drives the PCB board pressing plate 88 to separate from the PCB board body 4, and at this time, the fixed suction cup 711 cancels the fixation of the PCB board body 4. Then, the loading module 6 drives the positioning substrate 610 to reset, so that the positioning substrate 610 separates from the PCB board.

[0070] Then, through the combined action of the Y-axis servo motor 14 and the X-axis servo motor 17, the PCB board body 4 is moved to the position of the PCB board printing clamping mechanism 2. The PCB board printing clamping mechanism 2 clamps the PCB board body 4 again. Then, the clamping cylinder 51 of the PCB board clamping mechanism 5 opens the PCB board pressing block 55, so that the PCB board pressing block 55 separates from the PCB board body 4. Then, the vertical printing auxiliary loading mechanism 1 resets to the original position to complete the material taking action.
