Description

200524734 V. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a method for image positioning of a dual-table screen printing machine and its combination 5 especially for a dual-table screen printing machine for image energy; Positioning operation method and device thereof. Coincidentally [prior art] According to the press, the screen printing machine has two Ls of single table and double table ;: Double r has: It is characterized by providing a large number of screen printing ϋ cup _ ΰ enhancers, please refer to Patent Publication No. 5421 for cooperation 〇4 "Double sample brush machine structure", as shown in -⑷! Known double table screen printing machine, No., β); ^ The first plate (2b) reciprocates on the slide (7, 8), so that jm ^ No.-platen (2 b) is replaced in turn, let the net Printing presses continue printing:; effect; = brush time to replace the other-the floor of the printed matter, to reach its printing ϋ 然 πran, the conventional double-bed screen printing press, of which the first (2a), the first = ) Two adjustment elements can be set on the side to adjust the u-axis of the platen, and the adjustment element-f ΐ is to fix the substrate on the platen for plate alignment. After the ^ 疋 position is completed, the conveying platen is transported to The printing area is printed again. When the plate is aligned, the printing area below the (-(2a) and the second platen (2;) platen side plate. ί ί axis, Y axis and " Make the pattern and the substrate kiss plate) (entrance plate) When the plate is aligned, the second plate (down) must be withdrawn. Space: is the first plate (on the upper plate) The screen version, the off-screen version, and the first table (lower table) are not available, so the pattern of the stencil and the substrate are aligned.

Page 5 200524734 Description of the invention (2) The first and second plates with the mouth A ,,, and stamped money are placed in the slide rails for rotation, and the second plate is partially fixed to the Track, so the first plate can be adjusted normally when the structure is adjusted, but when the second plate is aligned, the adjustment clock is blocked by the machine. The operator must move the standing position to adjust the front and rear elements and one left and right adjustment element. Inconvenience of adjustment, in operation: This serious lack, the operator will inevitably have a misalignment. 'Obviously face to face =, the accuracy of the road f (PCB) is quite insufficient, the quality cannot be stabilized, and the work and staff are interrupted It will also be quite slow and not productive. As screen printing machines have been widely used in printed circuit boards (PCBs), the brushing technology has also improved with the increasing precision of electronic products. Therefore, when printing substrates to be printed, it must be assisted by an effective positioning system. For example, the princess princess ^ Shan 489740 "Structure improvement of CCD automatic positioning system" = the display seat (2 2) for e and CCD components (2 3), respectively control two c CD components (?? in the X axis And γ 2 load beams (13) and (14) are positioned on the left and right (x-axis) sliding positions, and it is known that the CCD component (23) described in the previous case can only be loaded on the load beams (13), (14). ) By the guide screw to make reciprocating motions; however, the composition used in the previous case is numerous, and its cost is increased, and the component failure rate is relatively frequent.

The purpose of its precise positioning is completely incompatible with fast operation and economic efficiency. [Abstract] I The purpose of the present invention is to provide a dual-tablet screen printer image positioning and its device, which can quickly move the image sensor. All of the ^ pieces are known that the conventional technology is simple and early, and the cost is greatly reduced. Fewer components will make the failure rate lower: and it can also achieve the purpose of precision printing positioning, which is quite effective;
