Description

Technical Field

[0001] The present invention relates to the technical field of circuit board processing, and in particular to a multifunctional automatic feeding device suitable for a PCB product line. Background Art

[0002] In today's electronic manufacturing industry, printed circuit boards (PCBs) are key components of various electronic products, and their production efficiency and quality are crucial to the development of the entire industry. As electronic products continue to develop towards miniaturization and multi-functionality, the requirements for PCB precision and integration are increasing, which also poses higher challenges to each link in the PCB production line.

[0003] Traditional PCB feeding equipment has relatively simple functions and can only feed specific types of materials. When faced with diverse material demands, it is necessary to frequently replace feeding equipment or perform complex manual adjustments, which not only consumes a lot of time and labor costs, but is also prone to human errors, resulting in low production efficiency and unstable product quality. In addition, as the scale of production expands, traditional feeding equipment cannot meet the needs of large-scale, high-speed production, and it is difficult to achieve efficient collaboration with modern automated production lines.

[0004] In conjunction with the above content, it should be explained that: Chinese patent application number CN2014201322900 discloses an automatic circuit board feeding device, wherein a vertically lifting conveying frame sucks up the circuit board through a suction cup above the circuit board, and no longer occupies a plane space and realizes the conveying and transportation of the circuit board. However, when the stacked groups of circuit boards are pushed to the processing area in sequence, the bottom of the circuit board contacts and rubs against the channel, which not only causes local wear of the circuit board, but also causes the position of the circuit board to change during the friction movement, resulting in an overall abnormal state of the circuit board when entering the processing area.

[0036] A sliding cylinder frame 301 is arranged on one side of the grabbing mechanical mechanism 3, and a sub-frame 303 close to the edge adjustment mechanism 6 is arranged on the side of the sliding cylinder frame 301, and an adjusting cylinder frame 302 is slidably connected to the top of the sliding cylinder frame 301 and the sub-frame 303, and a torque adjusting cylinder frame 304 connected to the combined suction cup 305 is slidably matched on the end surface of the adjusting cylinder frame 302, and an alarm light is arranged on the top of one end of the sliding cylinder frame 301 close to the material conveying frame 1.

[0037] The semi-finished PCB circuit board is transported by the material conveying rack 1 to the bottom of the grabbing mechanical mechanism 3. The grabbing mechanical mechanism 3 drives the adjusting cylinder rack 302 to move through the sliding cylinder rack 301, which is used to drive the adjusting cylinder rack 302 to move above the semi-finished PCB circuit board. The adjusting cylinder rack 302 drives the torque regulating cylinder rack 304 to move the combined suction cup 305 above the semi-finished PCB circuit board.

[0041] While the rotating docking station 4 is docking with the edge adjustment mechanism 6, the transferred semi-finished PCB circuit board is transported to the printing machine, which performs double-sided printing on it. The symmetrical plate conveyor belt 403 is designed with a narrow belt structure and is only used to contact the bottom of both sides of the semi-finished PCB circuit board. Therefore, there are no obstructions on the top and bottom centers of the semi-finished PCB circuit board. Combined with an adapted printing machine, it is printed on both sides simultaneously.

[0042] A fixed side frame 402 is provided on one side of the top of the rotating docking platform 4, and a movable side frame 404 is provided on the other side of the top of the rotating docking platform 4. A frame moving drag chain 405 connected to the top of the rotating docking platform 4 is provided at the bottom of the movable side frame 404. A plate conveyor belt 403 is symmetrically provided on the inner wall of the frame between the fixed side frame 402 and the movable side frame 404. A plurality of sets of sliders are slidably sleeved between the movable side frame 404 and the rotating docking platform 4, and the sliders are located at both ends of the frame moving drag chain 405.

[0043] Special motors are provided at the bottom of the two sets of plate conveyor belts 403 to drive them to operate according to the needs of printing and processing. During the processing of special semi-finished PCB circuit boards, after single-sided printing is completed, the special semi-finished PCB circuit boards are returned from the printing machine to the rotary docking table 4, and the lifting cylinder 407 drives the rotary docking table 4 to slide up, and the docking servo motor 406 drives the rotary docking table 4 to rotate 90° through the rotating part until the rotary docking table 4 is docked with the flip feeding docking table 5, and the special semi-finished PCB circuit boards are transferred to the flip feeding docking table 5.

[0044] Embodiment 2: This embodiment is a multifunctional automatic feeding equipment suitable for PCB product lines, including a flip feeding docking station 5, on the side away from the combined drag box 2, a material frame conveyor is arranged, an integrated conveying beam 501 is arranged on the top of one end of the flip feeding docking station 5, and a split conveying beam 505 is arranged side by side on the end face of the integrated conveying beam 501, and a material frame conveyor belt is arranged on the inner wall of the beam body between the integrated conveying beam 501 and the split conveying beam 505, and a jet rack 506 is arranged on the top of one side of the integrated conveying beam 501 and the split conveying beam 505, and the jet rack 506 is connected to the external air supply equipment pipeline for guiding the airflow into the jet rack 506 to pneumatically clean the surface of the passing material frame and circuit board, and a plurality of groups of rectangular notches are arranged in the middle of the split conveying beam 505, and the material frame conveyor belt is pulled away from the rectangular notches by special rollers.

[0045] A lifting cylinder 502 is disposed at the other end of the flip feeding docking platform 5, a rotating cylinder 503 is disposed at one end of the lifting cylinder 502, and a pneumatic clamp 504 close to the rectangular recess is disposed on the end surface of the rotating cylinder 503.

[0046] The special semi-finished PCB circuit board is transferred to the rectangular recessed area by the material frame conveyor belt, and the pneumatic clamp 504 is driven by the external air supply device to clamp the special semi-finished PCB circuit board along the rectangular recessed area, and the lifting cylinder 502 drives the pneumatic clamp 504 to slide upward, and the rotary cylinder 503 drives the pneumatic clamp 504 to rotate, so as to flip the special semi-finished PCB circuit board and reset it to the material frame conveyor belt, and then it is transferred to the printing machine by the rotary docking table 4 to realize double-sided targeted printing processing.

[0047] When idle, automatic framing is achieved through the branch line. The rotating docking station 4 transports a single set of semi-finished PCB circuit boards to the flip feeding docking station 5 in advance, and is clamped by the pneumatic clamp 504. The external material frame conveyor transports the single set of circuit board adapter material frames to the rectangular recessed area, and the pneumatic clamp 504 slides the clamped semi-finished PCB circuit boards down and clamps them into the circuit board adapter material frame. Combined with the operation of the external robotic arm, the two are temporarily assembled, and with the cooperation of the rotating docking station 4, they are transferred to the printing press for processing or external delivery.

[0048] It should be noted that it is also applicable to the feeding types of automatic flipping processing and jig production during BOT surface production, automatic loading and framing of TOP surface production, and one-key switching of multiple modes during BOT surface production and auxiliary jig production; it automatically identifies line change information during TOP surface production, automatically identifies specifications based on products and adjusts the relative track width, and is suitable for the production of different models. It is adjusted specifically according to actual production needs and is not limited to graphics and text. The device can be replaced according to actual production needs.

[0049] Embodiment 3: Circuit board transportation regularity supervision system: When the semi-finished PCB circuit board moves from the production conveyor rack 1 through the machine type identification card 101, the machine type identification card 101 collects the plate type data of the group of semi-finished PCB circuit boards in real time through the internal scanning sensor and high-definition camera, and the plate type data includes the external dimensions, model and traceability information, and sends the plate type data to the inside of the feed controller. The feed controller is internally provided with a connection with the core server of the plant's general supervision center, and the standard data related to the PCB board production is obtained based on this. Therefore, the external dimensions, model and traceability information in the plate type data are compared and analyzed with the standard data one by one.

[0050] The model is compared with the model library of standard data to determine, the traceability information is compared with the design library of standard data, and the external dimensions are compared with the board specifications of standard data to see if there are any errors. If the model and traceability information are compared abnormally, or the external dimensions exceed the upper limit of 3% of the error amount, a return inspection signal is generated, and it is judged that there is an abnormality in this group of semi-finished PCB circuit boards. The return inspection signal is sent to the feed controller, and the feed controller generates a text message in the style of "Daily Group Sequence 462, External Exceeding Limit / Return Inspection Processing" according to the return inspection signal, and displays it on the display screen of the feed controller. At the same time, the warning light is controlled to flash, and the return inspection signal record of the generated text information is stored and sent to the core server of the plant's general supervision center to generate an abnormal processing log for subsequent retrieval and verification.

[0051] After the feeding controller receives the return inspection signal, it immediately controls the material grabbing mechanical mechanism 3 to operate. The material grabbing mechanical mechanism 3 drives the adjusting cylinder frame 302 to move along the upper axial direction of one end of the production material conveying frame 1 through the sliding cylinder frame 301. The adjusting cylinder frame 302 drives the torque regulating cylinder frame 304 to move above the group of semi-finished PCB circuit boards. The torque regulating cylinder frame 304 drives the combined suction cup 305 to slide down, absorb the group of semi-finished PCB circuit boards, and absorb them from the production material conveying frame 1 to the return inspection conveying frame. The return inspection conveying frame is installed side by side on the side of the production material conveying frame 1. Figure 2 As shown, the production conveyor rack 1 has the same structure as the return-inspection conveyor rack. Specifically, depending on which group of equipment is connected to the external PCB production area equipment during the operation of a single group of equipment, that group is marked as the production conveyor rack 1, and the other group is marked as the return-inspection conveyor rack.

[0052] If the model and traceability information are correctly compared and the external dimensions are within the upper limit of 3% of the error, no signal will be generated, and only the edge adjustment mechanism 6 and the rotating docking station 4 will be adjusted according to the plate type data. The propulsion cylinder 605 of the edge adjustment mechanism 6 adjusts the moving distance of the torque adjustment slide 604 on the guide tube by the propulsion cylinder 605, so as to ensure the conveying position of the semi-finished PCB circuit board when it passes through the edge adjustment mechanism 6, while the rotating docking station 4 drives the movable side frame 404 to move through the frame moving drag chain 405, thereby increasing the distance between the movable side frame 404 and the fixed side frame 402, so as to connect and convey the semi-finished PCB circuit board with adjusted transportation trajectory.

[0053] In combination with Embodiment 1, Embodiment 2 and Embodiment 3, the present invention has many advantages: in terms of material transportation, the material grabbing mechanical mechanism 3 accurately clamps the semi-finished PCB circuit board through a multi-stage cylinder, and the edge adjustment mechanism 6 automatically adjusts according to the width of the circuit board, thereby realizing efficient and stable transportation from the production area to the printing press, and improving the transportation efficiency and accuracy.

[0054] In the printing process, the printing machine cooperates with the rotating docking station 4 and the flip feeding docking station 5. It can print conventional circuit boards on both sides simultaneously, and can also flip over and reprint special circuit boards. Multiple modes can be switched with one button to adapt to different production scenarios.

[0055] In terms of quality control, the transportation regularity supervision system collects plate data in real time and compares it with standards, quickly rechecks when abnormalities occur, and records information to ensure quality. At the same time, it can automatically identify specifications according to products, adjust related components, enhance versatility and adaptability, reduce equipment adjustment time, and improve production efficiency.
