In practical operation, in order to meet accuracy requirement, conventionally also can carry out repeatedly contraposition, the corresponding increase of vision-based detection number of times during contraposition, only needs to repeat above operation.Contraposition number of times is more, and aligning accuracy is higher, through repeatedly proofreading and correct repeatedly contraposition, can improve well aligning accuracy, and the selection of contraposition number of times is depending on accuracy requirement.
Finally the good film and the wiring board of contraposition is fixed up.Then reset, by the reset key on autocontrol system 103, control system 103 is controlled the 3rd drive unit 401, and driving device arm 602 rises and resets.
In the time need to carrying out the contraposition of the film of different size, only need by rotating control hand wheel 108, the spacing that regulates the camera of the first camera 701 and the camera of the second camera 801, can realize the visual test to the registration holes of the registration holes of the film of different size and wiring board.And install from different mounting holes 606 by mechanical finger 604, regulate the installation site of mechanical finger 604 on mechanical arm 602, can conveniently carry out the movement of pressing of the different size film.Realized thus the contraposition of the film of different size, especially, for large-sized film, 660mm * 550mm for example, prior art, when carrying out contraposition, is all easy to produce site error when drawing and placing large-size film, causes aligning accuracy low, therefore the film aligning machine that the present embodiment provides carries out contraposition to large-sized film well, has improved aligning accuracy.
Adopt this film aligning machine, aligning accuracy can reach error in 0.01mm.If carry out the two-sided contraposition of wiring board, only need carry out positive and negative twice operation can obtain the two-sided contraposition wiring board of high precision.
The film aligning machine that the utility model provides, first wiring board is placed on worktable 102 in use, then the film is placed in the circuit board, detection and location device is controlled the relative position that records the film and wiring board, detection and location device is controlled the 3rd drive unit 401 driving device arms 602 and in vertical plane, is done vertical movement, mechanical arm 602 moves downward to being gently pressed on the film, data analysis according to detection and location device to the film and wiring board relative position, the first drive unit 201 and the second drive unit 301 respectively driving device arm 602 are done transverse movement and in surface level, are made vertical motion in surface level, four-drive device 501 603 rotates mechanical arm 602 around the shaft, making mechanical arm 602 press the film moves horizontally and rotates, until the film and wiring board accurate contraposition.
The utility model by arranging drive unit on film aligning machine, make mechanical arm 602 in surface level, do respectively to do in transverse movement, surface level to do in vertical motion, vertical plane vertical movement and 603 rotate around the shaft, realize the multi-direction motion of mechanical arm 602, and the mode that adopts mechanical arm 602 to press the mobile film, reduced the relative displacement of the film in moving process and between wiring board, reduce bit errors, improved aligning accuracy, improved contraposition efficiency.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
