Description

Technical Field

[0001] The utility model relates to the field of printed circuit board manufacturing, in particular to a dislocation separation device used in the printed circuit board manufacturing. Background Art

[0002] In the manufacturing process of printed circuit boards, the unprocessed raw materials are usually called "substrates" or "base materials". Substrates are the basis of circuit board manufacturing. They provide physical support and electrical insulation properties for the manufacture of circuit boards.

[0003] The practice of assembling multiple unprocessed small substrates (also called "plates") horizontally and vertically into one piece and then cutting them is called "Panelization". Panelization is an important process in circuit board manufacturing. It effectively improves production efficiency, reduces costs, reduces material waste, and improves testing efficiency by connecting multiple plates together for unified processing and subsequent cutting. When these unprocessed plates are assembled together, they are called "sheets" or "plates". During the cutting process, the "sheets" or "plates" will be cut into multiple independent plates (i.e. small substrates), and each plate will eventually become a complete circuit board.

[0004] After being cut and processed by the cutting equipment, the "sheet" or "plate" will form parallel-arranged plates, that is, independent substrates arranged in parallel. Then the cut substrates need to be washed and dried for use in subsequent production processes. There are usually two existing operating methods. The first is that the operator collects the cut substrates together and then transports them to a washing and drying machine, and sends the substrates one by one into the washing and drying machine for washing and drying. This method is inefficient and can easily cause damage to the substrates during transportation. The second is that the independent substrates arranged in parallel formed after being cut and processed by the cutting equipment are sent to the washing and drying machine after a section of conveyor line for washing and drying. However, since the multiple substrates formed after cutting by the cutting equipment are usually cut against each other or have a small gap in the vertical direction along the conveyor line, if they are directly sent to the washing and drying machine, the two substrates in the vertical direction of the conveyor line will be The moisture in the area between the two substrates is difficult to dry, which will seriously affect the subsequent processing procedures of the substrate. Therefore, operators usually have to separate or push the substrates that are pressed against each other on the conveyor line to increase the gap between the two substrates in the vertical direction along the conveyor line, thereby avoiding the problem of moisture in the area between the two substrates after passing through the water washing and drying machine. However, this method also requires special operators, and the two substrates must be manually separated or pushed apart in real time. The operation intensity is high. Once the operator is distracted or leaves the post for other reasons, defective products will occur (that is, some substrates still have moisture on the sides after passing through the water washing and drying machine), which places extremely high demands on the operator's position.

[0005] In view of the above problems, it is necessary to study and design a device that can automatically separate the parallel arranged substrates after cutting. Utility Model Content

[0006] The utility model aims to provide a dislocation separation device for manufacturing printed circuit boards to solve at least one of the above technical problems.

[0007] According to one aspect of the utility model, there is provided a dislocation separation device for manufacturing a printed circuit board, comprising:

[0008] Conveyor lines for conveying printed circuit boards;

[0009] At least one first suction cup component for sucking the printed circuit board on the conveyor line;

[0010] At least one second suction cup component for sucking the printed circuit board on the conveyor line, the first suction cup component and the second suction cup component are arranged in a direction perpendicular to the conveying direction of the conveyor line,

[0011] When the number of the first suction cup components is plural and / or the number of the second suction cup components is plural, the first suction cup components and the second suction cup components are arranged at intervals;

[0012] A first driving device, the first driving device can drive the first suction cup component and the second suction cup component to move up and down;

[0013] A second driving device, the second driving device can drive the second suction cup component to reciprocate along the conveying direction of the conveying line; and

[0015] The dislocation separation device of the utility model is installed between the cutting equipment and the washing and drying machine. The height of the frame can be adjusted by the supporting feet, so as to adjust the height of the conveying line so that the height of the conveying line is kept flush with the output end of the cutting equipment and the input end of the washing and drying machine, ensuring that the substrates of the printed circuit board can be smoothly conveyed. The cutting equipment cuts the unprocessed assembled substrates, that is, the cutting equipment cuts the "sheet materials". The multiple substrates arranged in parallel along the conveying direction of the conveying line formed after the cutting by the cutting equipment enter the conveying line for conveying. When the multiple substrates arranged in parallel are conveyed to below the first suction cup component and the second suction cup component, the first driving device drives the first suction cup component and the second suction cup component to move downward so that the first suction cup component and the second suction cup component suck the substrates arranged in parallel, and then the first driving device drives the first suction cup component and the second suction cup component to move upward. Under the action of the second driving device, the second suction cup component sucks the substrates along the conveying direction. The conveying direction of the conveying line moves forward, and then the first suction cup component and the second suction cup component release the substrate at the same time. Since the first suction cup component and the second suction cup component are arranged at intervals in a direction perpendicular to the conveying direction of the conveying line, after entering the washing and drying machine, the substrate sucked by the first suction cup component and the second suction cup component will be staggered and separated front and back on the conveying line, so that the substrates originally arranged in parallel on the conveying line are staggered and separated front and back along the conveying direction of the conveying line, and the substrates will not be basically abutted against the adjacent ones, and the gap between every two substrates is large, so that each substrate after passing through the washing and drying machine remains dry, avoiding the problem of moisture in the parts between the substrates after passing through the washing and drying machine. The staggered separation device of the utility model can not only ensure the drying effect of each substrate after passing through the washing and drying machine, but also save labor, realize the assembly line operation of printed circuit board cutting, washing and drying, and improve the manufacturing efficiency of printed circuit boards.

[0071] When the number of the first suction cup components 2 is multiple and / or the number of the second suction cup components 3 is multiple, the first suction cup components 2 and the second suction cup components 3 are arranged at intervals along a direction perpendicular to the conveying direction of the conveying line 1; Figure 2 and Figure 3 In this embodiment, the number of the first suction cup components 2 and the second suction cup components 3 are both three. Before the staggered separation device of the utility model works, the three first suction cup components 2 and the three second suction cup components 3 are arranged at intervals along a direction perpendicular to the conveying direction of the conveyor line 1. This is suitable for the application scenario where six substrates arranged in parallel along the conveying direction of the conveyor line 1 after being cut by the cutting equipment enter the conveyor line 1 in parallel for conveyance.

[0072] See also Figure 1The dislocation separation device of the utility model is installed between the cutting equipment and the washing and drying machine. The overall height of the dislocation separation device can be adjusted by the support foot 141 so that the height of the conveyor line 1 is kept flush with the output end of the cutting equipment and the input end of the washing and drying machine, ensuring that the substrate of the printed circuit board can be smoothly conveyed. The three first negative pressure suction cups 21 are connected to the external negative pressure source, and the three second negative pressure suction cups 31 are connected to the external negative pressure source. The cutting equipment cuts the unprocessed assembled substrates, that is, the cutting equipment cuts the "sheet materials". The six substrates arranged in parallel along the conveying direction of the conveyor line 1 formed after the cutting by the cutting equipment enter the conveyor line 1 for conveyance. When the six parallel arranged substrates are conveyed to the bottom of the three first suction cup components 2 and the three second suction cup components 3 arranged in parallel and at intervals, the photoelectric sensor can be used to detect whether the substrate is conveyed to the bottom of the first suction cup component 2 and the second suction cup component 3. When the photoelectric sensor detects the substrate, the first drive device 4 starts to work, and the first drive device 4 drives the carrier plate 7 along the two The first guide column 9 moves downward, and the carrying plate 7 drives the first longitudinal connecting plate 12, the three first suction cup components 2, the second driving device 5, the shaft sleeve 11, the second guide column 10, the moving plate 8, the second longitudinal connecting plate 13, and the three second suction cup components 3 to move downward synchronously as a whole. Due to the action of the first spring 23 and the second spring 33, the first negative pressure suction cup 21 and the second negative pressure suction cup 31 can be attached to the substrate in a buffering manner to avoid the first negative pressure suction cup 21 and the second negative pressure suction cup 31 from being in rigid contact with the substrate and causing damage to the substrate. When the first negative pressure suction cup 21 at the bottom of the first negative pressure suction cup 21 When the attachment port 211 and the second negative pressure suction port 311 at the bottom of the second negative pressure suction cup 31 are attached to the substrate, the external negative pressure source works so that the three first negative pressure suction cups 21 and the three second negative pressure suction cups 31 respectively suck the six substrates arranged in parallel, and then the first driving device 4 drives the carrying plate 7 to move upward along the two first guide pillars 9 to a certain height, and the carrying plate 7 drives the first longitudinal connecting plate 12, the three first suction cup components 2, the second driving device 5, the shaft sleeve 11, the second guide pillar 10, the moving plate 8, the second longitudinal connecting plate 13, and the three second suction cup components 3 as a whole. Move upward to a certain height, and then the second driving unit device 5 drives the moving plate 8 and the second longitudinal connecting plate 13 to move forward along the conveying direction of the conveyor line 1, and the second longitudinal connecting plate 13 drives the three second suction cup components 3 to move forward along the conveying direction of the conveyor line 1 synchronously, that is, the three second negative pressure suction cups 31 suck the substrate and move forward along the conveying direction of the conveyor line 1. When the three second negative pressure suction cups 31 move forward a certain distance along the conveying direction of the conveyor line 1, at this time, the three first negative pressure suction cups 21 and the three second negative pressure suction cups 31 are staggered front and back along the conveying direction of the conveyor line 1 ( Figure 7 Then, the external negative pressure source stops working, and the three first negative pressure suction cups 21 and the three second negative pressure suction cups 31 release the substrate at the same time (after releasing the substrate, the three first negative pressure suction cups 21 and the three second negative pressure suction cups 31 are reset to Figure 1 The state shown is to wait for the next operation), because the three first suction cup components 2 and the three second suction cup components 3 are arranged at intervals along the direction perpendicular to the conveying direction of the conveyor line 1 and the three first negative pressure suction cups 21 and the three second negative pressure suction cups 31 are staggered and distributed front and back along the conveying direction of the conveyor line 1 at this time, after releasing the substrate, the three substrates sucked by the three first negative pressure suction cups 21 and the three substrates sucked by the three second negative pressure suction cups 31 will be staggered and separated and distributed on the conveyor line 1 front and back, with three substrates in the front and three substrates in the back, keeping a certain distance between each other, so that the substrates originally arranged in parallel on the conveyor line 1 The six substrates are staggered and separated front and back along the conveying direction of the conveyor line 1. Each substrate will not be basically abutted against the adjacent ones, and the gap between each two substrates is very large. After the substrates enter the water washing and drying machine in such an arrangement, it can ensure that each substrate remains dry after passing through the water washing and drying machine, avoiding the problem of moisture in the parts between the substrates after passing through the water washing and drying machine. The staggered separation device of the utility model can not only ensure the drying effect of each substrate after passing through the water washing and drying machine, but also save labor, realize the assembly line operation of printed circuit board cutting, water washing and drying, and improve the manufacturing efficiency of printed circuit boards.

[0073] When the dislocation separation device of the utility model is in operation, the first negative pressure suction cup 21 will only suck up the substrate, but will not move the sucked substrate forward along the conveying direction of the conveyor line 1. Only the second negative pressure suction cup 31 will move the sucked substrate forward along the conveying direction of the conveyor line 1. In this way, the second suction cup component 3 can be moved forward only a short distance along the conveying direction of the conveyor line 1 to quickly make the six substrates dislocated and separated front and back on the conveyor line 1. If the first suction cup component 2 is not provided, since the conveyor line 1 always keeps conveying, the second suction cup component 3 needs to be moved forward a long distance along the conveying direction of the conveyor line 1 to make the six substrates dislocated and separated front and back on the conveyor line 1, and the second suction cup component 3 also needs to be moved a long distance to be reset, which will reduce the conveying efficiency of the substrate.

[0075] See also Figure 8 The six substrates 15 arranged in parallel along the conveying direction of the conveying line 1 formed after cutting by the cutting equipment enter the conveying line 1 for conveying, and the six parallel arranged substrates 15 are conveyed to the bottom of the three first suction cup components 2 and the three second suction cup components 3 arranged in parallel and at intervals.

[0078] Fig.10 Schematically shows Figure 1 The third working state of the offset separation device is shown.

[0079] then Fig. 9 The second working state shown is shown in FIG. Fig.10 Under the action of the first driving device 4, the three first negative pressure suction cups 21 drive the three sucked substrates 15 and the three second negative pressure suction cups 31 drive the three sucked substrates 15 to move upward to a certain height.

[0080] Fig.11 Schematically shows Figure 1 The fourth working state of the offset separation device is shown.

[0081] then Fig.10 The third working state shown, see Fig.11 , under the action of the second driving device 5, the three second negative pressure suction cups 31 drive the three sucked substrates 15 to move forward to a certain position along the conveying direction of the conveyor line 1, and then the external negative pressure source stops working, and the three first negative pressure suction cups 21 and the three second negative pressure suction cups 31 release the substrates 15, and the three substrates sucked by the three first negative pressure suction cups 21 and the three substrates sucked by the three second negative pressure suction cups 31 will be distributed on the conveyor line 1 in a front-to-back dislocation and separation manner, with three substrates in the front and three substrates in the back, and a certain interval is maintained between each other, so that the six substrates originally arranged in parallel on the conveyor line 1 are dislocation and separation in the front-to-back direction of the conveyor line 1, and each substrate will not be basically abutted against the adjacent substrates, and the gap between every two substrates is large, and the next step is to reset the three first negative pressure suction cups 21 and the three second negative pressure suction cups 31 to Figure 1 The state shown is to wait for new parallel arranged substrates to enter the conveyor line 1 for the next operation.
