The invention is described in detail below with reference to the figures and the specific embodiments.
As shown in fig. 1-4, the present invention provides a PCB character digital double-table high-speed jet printing machine, which comprises a workbench 10, wherein two longitudinal axis modules (11, 12) are arranged on the workbench 10 along the longitudinal direction of the workbench 10, jet printing stations (21, 22) are arranged on two sides of each longitudinal axis module (11, 12), and the longitudinal axis modules (11, 12) can drive the jet printing stations (21, 22) to reciprocate along the longitudinal direction of the workbench 10. In order to keep the movable stability of the jet printing stations (21, 22), guide rails (13, 14) are respectively arranged on two sides of the two longitudinal axis modules (11, 12), and two sides of the jet printing stations (21, 22) are connected to sliding blocks of the guide rails (13, 14) so as to keep balance of the two sides of the jet printing stations (21, 22).
A jet printing mechanism 30 arranged along the transverse direction of the worktable 10 is arranged above the worktable 10, the jet printing mechanism 30 is provided with 4 first transverse-axis modules (34, 35, 36, 37) arranged along the transverse direction of the worktable 10, and each first transverse-axis module (34, 35, 36, 37) is provided with an ink jet head assembly (41, 42, 43, 44).
Before the printing, the printing area 50a of the PCB 50 may be divided into four sub-areas, namely, a sub-area 50b, a sub-area 50c, a sub-area 50d and a sub-area 50e, according to the moving distance of the four inkjet head assemblies (41, 42, 43, 44), the inkjet head assembly 41 corresponds to the sub-area 50b, the inkjet head assembly 42 corresponds to the sub-area 50c, the inkjet head assembly 43 corresponds to the sub-area 50d, and the inkjet head assembly 44 corresponds to the sub-area 50 e.
During jet printing, the PCB 50 is sent to the lower part of the jet printing mechanism 30 through the longitudinal module 21, and then the ink jet head assemblies (41, 42, 43 and 44) are driven to carry out character jet printing on the sub areas (50 b, 50c, 50d and 50 e).
In the process of jet printing, the four ink jet head assemblies (41, 42, 43, 44) can act independently or simultaneously as required, for example, when four sub-areas (50 b, 50c, 50d, 50 e) of the PCB 50 are sent to the lower part of the jet printing mechanism 30, only the sub-area 50b corresponds to character jet printing, and the ink jet head assemblies 41 can be directly driven to act; if the sub-regions (50 b, 50 d) are corresponding to character jet printing, the ink jet head assemblies (41, 43) can be driven to operate at the same time, and so on.
According to the invention, an original transverse axis module is divided into a plurality of small first transverse axis modules, each small first transverse axis module is respectively provided with the ink jet head assembly, and each ink jet head assembly is responsible for the area covered by the active area, so that the ink jet printing area on the PCB is equivalently divided into a plurality of sub-areas, each ink jet head assembly corresponds to one sub-area, and during ink jet printing, the ink jet head assembly is only responsible for carrying out character ink jet printing on the corresponding sub-area, so that the ink jet head is prevented from moving for a long distance to carry out ink jet printing, each ink jet head assembly can move for ink jet printing in the small area quickly, convenience is provided for moving the ink jet printing of the PCB, and the ink jet printing efficiency is further improved.
(2) Every inkjet head subassembly all is driven by independent first cross axle module, at broken spout the seal in-process, and each inkjet head subassembly can spout the seal to each subregion simultaneously, improves greatly and spouts seal efficiency.
In the embodiment of the invention, the sum of the transverse lengths of the four first transverse-axis modules (34, 35, 36, 37) along the workbench 10 is greater than the width of the PCB to be processed, namely the width of the four ink jet head assemblies capable of covering the PCB to be processed is used for performing jet printing on any point on the PCB.
Preferably, two adjacent first transverse modules are arranged in a staggered manner. Because the both ends of cross axle module all can set up the end socket, the ink jet head subassembly is the activity of making a round trip between two end sockets, if arrange four first cross axle modules on same straight line, then can lead to the actual activity of ink jet head subassembly can not completely cover the width activity of taking processing PCB board. From this, through arranging adjacent two first cross axle modules dislocation each other to make the end seat of adjacent first cross axle module misplace each other, the activity interval of adjacent inkjet head subassembly can seamless butt joint, thereby ensures that four inkjet head subassemblies can cover the width of treating the processing PCB board.
Specifically, the inkjet printing mechanism 30 is provided with a T-shaped fixing base 33 arranged along the horizontal direction of the table 10, and adjacent first transverse shaft modules are arranged on both sides of the vertical portion of the T-shaped fixing base 33, so that the first transverse shaft modules are staggered and can be arranged in a staggered manner.
More specifically, the bottom of the first cross shaft module is connected to the vertical side of the T-shaped fixing seat 33, so that the sliders of the adjacent first cross shaft modules are disposed outward relative to the T-shaped fixing seat 33, the inkjet head assemblies are disposed below the first cross shaft modules through the cantilevers 341 disposed in the vertical direction, and the adjacent inkjet head assemblies are disposed opposite to each other.
In other embodiments, as shown in fig. 5, the motion paths of the adjacent first horizontal axis modules overlap at adjacent positions, and the length of the overlapping area is d, so as to provide a redundant area for the movement of the first horizontal axis module, and ensure that the inkjet-printed characters do not form a dividing line on the boundary line of the two sub-areas, which affects the inkjet printing effect of the characters.
In the embodiment of the present invention, the inkjet printing mechanism 30 may be provided in two or one.
When the number of the jet printing mechanisms 30 is two, each jet printing mechanism corresponds to one jet printing mechanism, and the two jet printing mechanisms work alternately during jet printing.
When the jet printing mechanism 30 is provided with one, a second transverse shaft module 32 arranged along the transverse direction of the workbench is additionally arranged, the transverse shaft module is fixed on a transverse beam 31 of the jet printing mechanism, and a T-shaped fixed seat 33 is connected on a sliding part of the second transverse shaft module 32. When in spray printing, the second transverse axis module 32 drives the spray printing mechanism to move back and forth between the two spray printing stations (21, 22), and when one of the spray printing stations 21 is in a loading and unloading state, the second transverse axis module 32 drives the spray printing mechanism to move to the upper part of the other spray printing station 22 so as to spray print the PCB on the spray printing station 22.
Because spout the seal mechanism and adopt a plurality of inkjet head subassemblies to spout the seal simultaneously to four subregion of PCB board, it is very high to spout seal efficiency, spouts the seal mechanism and can just can accomplish and spout seal work during the loading and unloading of another spout seal station. Even if adopt one to spout seal mechanism, also can realize two seamless connection who spouts the seal station.
In the embodiment of the present invention, as shown in fig. 6, the inkjet head assembly 41 includes a plurality of high-speed inkjet heads 411 arranged in a staggered manner, and the model of the high-speed inkjet heads 411 is bernal LC 2000. Of course, other high-speed jet heads may be used as desired, such as the XAAR 1001 model available from Seal corporation
