Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of PCB board processing and manufacturing, and particularly discloses a PCB board automatic production and processing system. BACKGROUND

[0002] A PCB board is a board used for supporting and connecting electronic components. In the production process of the PCB board, a series of processing operations such as drilling, electroplating, etching and printing need to be performed. In addition, for double-sided PCB boards, the two sides of the board also need to be processed. In a PCB board processing device that does not support double-sided synchronous processing, a corresponding turnover mechanism is usually assembled to process the PCB board by turning over. However, in the turnover process, especially for flexible PCB boards, the processing position may deviate after turning over, which affects the processing precision of the PCB board and even causes the product to be scrapped. Some processing devices are equipped with positioning structures or automatic correction mechanisms to ensure the position precision of the PCB board after turning over.

[0003] In summary, in a PCB board processing device that does not support double-sided synchronous processing, the PCB board is automatically turned over by a specially set turnover mechanism, and the turnover is positioned by setting a positioning structure or an automatic correction mechanism, which increases the complexity and maintenance difficulty of the device and also increases the overall cost of the device.

[0033] As shown in Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, the suction gripper plate 431 for sucking and grabbing the PCB is welded on the grabbing arm 43, and the suction gripper plate 431 is also a pneumatic suction plate with negative pressure suction holes, same as the main suction disc 22 and the auxiliary suction disc 24; two compression rollers 432 are horizontally rotatably installed on the grabbing arm 43 on the side opposite to the suction gripper plate 431; two pressure receiving blocks 233 are arranged on the lifting seat 232 and correspondingly contact the two compression rollers 432 when pressed, and the pressure receiving block 233 is obliquely cut from the upper end surface and provided with an inclined surface 2331; the inclined surfaces 2331 on the two pressure receiving blocks 233 in the two elastic supports 23 are arranged in an eight-character shape.

[0034] In the present application, the flexible PCB needs to be processed on both sides, and during the processing, the cooperation of the manipulator 4 and the suction fixing table 2 can automatically flip and change the surface of the PCB while grabbing and placing the PCB, and the specific process is described as follows:

[0035] Through the cooperation of the horizontal movement of the horizontal moving frame 32 and the lifting movement of the lifting assembly 33, the PCB can be sucked and grabbed by the manipulator 4 to the upper side of the suction fixing table 2, and the PCB is horizontally sucked between the two suction gripper plates 431, at this time, the suction gripper plates 431 are in a front-down state, and the two grabbing arms 43 do not interfere with the direct laying of the PCB. Under the driving of the lifting slide block 334, the manipulator 4 synchronously lowers the PCB, so that the PCB is placed on the upper end surface of the main suction disc 22 and the two auxiliary suction discs 24. In order to ensure that the PCB is completely attached to the upper end surface of the main suction disc 22, the manipulator 4 can continue to be lowered by a small height, and the two grabbing arms 43 are gradually correspondingly pressed on the two auxiliary suction discs 24 through the slow pressure frame 42, the supporting spring 235 is compressed, and the auxiliary suction disc 24 is slightly lowered. At this time, the part of the PCB in contact with the main suction disc 22 can be completely attached to the main suction disc 22, and then the main suction disc 22 sucks and fixes the PCB, and the two suction gripper plates 431 release the PCB. The lifting slide block 334 drives the manipulator 4 to rise, and the two auxiliary suction discs 24 start to rise and reset. Before the buffer pressure of the slow pressure frame 42 is completely released, the two auxiliary suction discs 24 actively suck the two side parts of the PCB, so as to complete the suction and fixation of the entire PCB, and then the non-fixed surface of the PCB can be processed.

[0036] When the single side of the PCB is finished, the lifting slider 334 drives the manipulator 4 to descend again, and the two negative pressure suction plates 431 are adsorbed and fixed on the fixed position of the PCB, then the main suction disc 22 and the auxiliary suction disc 24 are synchronized to release the adsorption of the PCB, the manipulator 4 is lifted to a certain height, and then the electric turntable 41 drives the manipulator 4 to turn 180 degrees, and the PCB is finished automatically. At this time, the negative pressure suction plate 431 is in the state of facing upward, the grabbing arm 43 is located below the PCB, and the two grabbing arms 43 interfere with the direct laying of the PCB. When the lifting slider 334 drives the manipulator 4 to descend for discharging, the two pressure rollers 432 on the grabbing arm 43 are pre-pressed on the two pressure blocks 233, and the auxiliary suction disc 24 is lowered synchronously with the lifting seat 232, then the auxiliary suction disc 24 avoids the grabbing arm 43, so that the middle part of the PCB can be directly contacted on the main suction disc 22, then the main suction disc 22 adsorbs and fixes the PCB, and then the negative pressure suction plate 431 releases the adsorption of the PCB, then the driving motor 441 is started, the two grabbing arms 43 are driven to slide back through the bidirectional screw 442, the pressure roller 432 is moved from the upper end surface of the pressure block 233 to the inclined surface 2331, and rolls along the inclined surface 2331. In the rolling process, as the pressure roller 432 gradually moves away, the auxiliary suction disc 24 and the lifting seat 232 are gradually reset and lifted. When the pressure roller 432 completely avoids the pressure block 233, the auxiliary suction disc 24 is reset, and the grabbing arm 43 moves away from the lower part of the PCB. The two auxiliary suction discs 24 adsorb and fix the two side parts of the PCB, so that the adsorption and fixation of the whole PCB after turning over are completed, and then the other side of the PCB can be processed.

[0037] The application provides a PCB automatic production and processing system, which is provided with a manipulator 4 for grabbing and actively turning over the PCB, and is provided with an adsorption and fixation table 2 for processing and fixing the PCB in cooperation with the manipulator 4, and the whole adsorption and fixation surface of the adsorption and fixation table 2 is composed of a main suction disc 22 and auxiliary suction discs 24 distributed on both sides. When the manipulator 4 places the PCB, the PCB can be completely contacted with the whole adsorption and fixation surface of the adsorption and fixation table 2 before and after turning over, and the adsorption and fixation of the PCB between the manipulator 4 and the adsorption and fixation table 2 is switched during the placing process, so that the movement dislocation of the processing and placing position is avoided.
