Detailed Description
In order to solve the problem of the prior art that the nozzle structure is manually moved to align the position of the circuit board, the inventor of the present invention has made many years of research and development to improve the scaling of the prior art, and will hereinafter describe in detail how to use an optical identification nozzle system to achieve the most efficient function.
Referring to fig. 1 to 4, fig. 1 is a schematic view of an optical recognition nozzle system according to the present invention. FIG. 2 is a schematic view of the optical recognition nozzle system according to the present invention, showing light spots irradiated onto a circuit board. FIG. 3 is a schematic view of a nozzle structure of the optical identification nozzle system of the present invention. Fig. 4 is a detailed schematic view of a nozzle structure of the optical recognition nozzle system of the present invention. However, the current suction device cannot automatically fine-tune the suction nozzle assembly to a preferred suction position according to the circuit board, and cannot automatically turn to the suction nozzle assembly to change the working surface, so the working efficiency of the suction device in the manufacturing process is often not as expected. Therefore, the embodiment of the invention provides an optical identification nozzle system which can effectively solve the above problems and can be adsorbed to a better position of a circuit board.
As shown in fig. 1 to 4, the optical identification nozzle system 100 of the present invention is used for identifying circuit boards 140 and adsorbing circuit boards 140, wherein each circuit board 140 is separated by a separation paper 150. The optical identification nozzle system 100 includes a plurality of nozzle structures 110, a Charge Coupled Device (CCD) image capturing module 120, and a control processor 130. Each nozzle structure 110 includes a nozzle body 112 and a light spot marking module 114. The optical marking module 114 is mainly used for emitting light to mark the circuit board 140 to see whether the whole nozzle structure 110 is aligned with the circuit board 140, as will be described further below.
As shown in fig. four, the light spot indication module 114 includes a power source 1141, a light emitting source 1142, a focusing module 1143 and a cover glass 1144. The nozzle body 110 has a suction pipe 1121, the spot marking module 114 is disposed on the nozzle body 112, the power source 1141 is used for providing power, the light source 1142 is connected to the power source 1141, and the light source 1142 is used for emitting light LK. The focusing module 1143 is used to adjust the light LK to be emitted in parallel or in a diffused manner. The focusing module 1143 is disposed between the light source 1142 and the cover glass 1144. The ccd image capturing module 120 is used for photographing the circuit board LK. The control processor 130 is connected to the nozzle structure 110 and the ccd image capturing module 120. In the embodiment of the invention, the light source 1142 of the light spot marking module 114 emits light LK to the circuit board 140, and then the ccd image capturing module 120 captures an image of the circuit board 140, and then the control processor 130 automatically determines whether the plurality of light spots LD on the circuit board LK are at proper positions according to the image of the circuit board 140 captured by the ccd image capturing module 120. In the embodiment of the present invention, the nozzle structures 110 are arranged in a matrix form and parallel to the circuit board 140, and in another embodiment, the nozzle structures 110 are arranged at random positions and parallel to the circuit board 140. In addition, in the present embodiment, the light LK emitted from the light source 1142 is a general strong light or laser light source.
If the control processor 130 determines that the light spot LD on the circuit board 140 is at a proper position, the nozzle structure 110 moves downward to perform an absorption action on the circuit board 140, wherein the nozzle body has an air suction duct 1121, and the air flow flows from bottom to top through the air suction duct 1121. If the control processor 130 determines that the light spots LD on the circuit board 140 are not at the proper positions, the suction nozzle structure 110 is moved to the proper positions according to the marks of the light spots LD on the image and through mechanism adjustment, the ccd image capturing module 120 is further used to capture images of the circuit board 140, and then the control processor 130 automatically determines whether the plurality of light spots LD on the circuit board LK are at the proper positions through the image of the circuit board 140 collected by the ccd image capturing module 120 until the positions are proper, so as to avoid being adsorbed to the separating paper 150.
That is to say, as can be seen from the above, the optical identification nozzle system 100 according to the embodiment of the present invention aligns the circuit board 140 to be adsorbed mainly through the light spot marking module and the ccd image capturing module 120, so as to complete the alignment of the nozzle structure 110 and the circuit board 140, thereby avoiding many problems in the past.
In another embodiment, after the light spot marking module 114 emits the light LK to the circuit board 140, whether the light spots LD on the circuit board 140 are at the proper positions can be identified by human eyes. If the light spot LD on the circuit board 140 is determined to be in the proper position by the naked eye, the suction nozzle structure 110 moves downward to perform the suction operation on the circuit board 140. If the light spot LD on the circuit board 140 is judged not to be in the proper position by the naked eye, the nozzle structure 110 is manually moved to the proper position according to the indication of the light spot LD.
In summary, the optical identification nozzle system of the present invention can achieve the following effects:
1. whether the circuit board is in a proper position or not can be judged quickly.
2. The circuit board can be positioned and adsorbed more efficiently and accurately to complete the related operation.
3. The production cost and the labor cost can be saved.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Therefore, all the equivalent changes or modifications according to the features and the spirit of the claims should be included in the claims of the present invention.
