The character jet printing machine provided by the invention comprises a frame body 1, a plate feeding conveying mechanism 2, a rotation deviation correcting mechanism 10, a displacement carrying platform 12 and a plate discharging conveying mechanism 13, wherein the plate feeding conveying mechanism 2, the rotation deviation correcting mechanism 10, the displacement carrying platform 12 and the plate discharging conveying mechanism 13 are sequentially arranged on the frame body 1; the rotary deviation rectifying mechanism 10 comprises a rotary deviation rectifying platform 6 for sucking and fixing the printed circuit board conveyed by the board feeding conveying mechanism 2, and a visual positioning system 16 is arranged above the rotary deviation rectifying platform 6; the displacement stage 12 comprises a slide rail 129, and a first lifting stage 121 and a second lifting stage 122 which move synchronously on the slide rail 129; the first lifting platform 121 and the second lifting platform 122 are both provided with air suction platforms 123 to realize the adsorption of the printed circuit board; a printing platform and a jet printing system 9 are also arranged above the shifting carrying platform 12.
By adopting the arrangement mode, the printed circuit board is conveyed to the rotary deviation rectifying platform 6 of the rotary deviation rectifying mechanism 10 by the board feeding conveying mechanism 2, and four sides of the printed circuit board are clamped and positioned by arranging the left and right side leaning positioning mechanisms arranged on the rotary deviation rectifying mechanism 10 and the front and rear side leaning mechanisms arranged on the visual positioning system 16; if the corrected position of the printed circuit board still has an error, the position of the printed circuit board is adjusted again by using the rotary deviation correcting mechanism 10, that is, the printed circuit board is further precisely positioned. Then, the positioned printed circuit board is transported to the lower side of the inkjet printing system 9 by the first elevating stage 121 of the shift stage 12, and the inkjet printing work is performed. After the jet printing, the printed circuit board after the jet printing is sent to the board discharging conveying mechanism 13 by the second lifting platform 122 of the shifting platform 12, thereby completing the character jet printing process. Therefore, the character jet printing efficiency can be effectively improved, and efficient production is realized.
Optionally, the board feeding and conveying mechanism 2 comprises a conveying rail 21 and a rail bracket 22 hinged to one end of the conveying rail 21; the plate feeding conveying mechanism 2 further comprises a piston cylinder 23, one end of which is connected with the conveying track 21 so as to realize the rotation of the conveying track 21 around the track bracket 22; the conveying rail 21 is also provided with a conveying belt 24 for conveying the printed circuit board; the board feeding transport mechanism 2 further includes a sensor 25 for detecting the printed circuit board to realize automatic rotation of the transport belt 24.
Specifically, in an initial state, the conveying rail 21 is in a horizontal position, and one end of the conveying rail 21 is hinged to the rail bracket 22, that is, one end of the conveying rail 21 is provided with a hinge point, and is hinged to the rail bracket 22 through the hinge point; further, one end of the piston cylinder 23 is connected to the transfer rail 21; in this way, the transmission rail 21 can be rotated about the hinge point by extending and contracting the piston cylinder 23, and the height of the end of the transmission rail 21 away from the hinge point can be changed. Meanwhile, the transfer rail 21 is also provided with a transfer belt 24 for transferring the printed circuit board and a sensor 25 for detecting the printed circuit board. That is, when the sensor 25 detects the approach of the printed circuit board, the conveyor belt 24 starts to rotate, and when the printed circuit board is placed on the conveyor belt 24, the printed circuit board moves forward due to the rotation of the conveyor belt 24; and the transmission rail 21 is driven by the piston cylinder 23, the transmission rail 21 rotates with the hinge point as the axis, that is, one end of the transmission rail 21 far from the hinge point sinks to form a slope, so as to transmit the printed circuit board of the transmission belt 24 to the rotation deviation rectifying platform 6 of the rotation deviation rectifying mechanism 10.
Preferably, the board feeding conveying mechanism 2 is provided with two groups of conveying rails 21 and two groups of conveying belts 24, the two groups of conveying belts 24 are arranged in parallel, and the conveying belts 24 are driven by a motor 26 to rotate; a timing belt is provided between the motor 26 and the two sets of conveyor belts 24 to ensure that the two sets of conveyor belts 24 arranged in parallel run synchronously to ensure that no offset occurs when the printed circuit board is conveyed forward.
Here, the horizontal height of the conveying rail 21 is higher than the height of the rotating deviation rectifying platform 6 of the rotating deviation rectifying mechanism 10 when the conveying rail 21 is in the horizontal position, so that when the end of the conveying rail 21 far from the hinge point sinks, the height of the end drops to be consistent with the height of the rotating deviation rectifying platform 6, thereby conveying the printed circuit board from the conveying belt 24 to the rotating deviation rectifying platform 6.
It should be noted here that after the end of the transmission rail 21 away from the hinge point sinks, the included angle between the transmission rail 21 and the horizontal position thereof may be determined according to the actual situation; that is, no matter how many angles the transfer rail 21 swings with respect to the rail bracket 22 or how much the stroke of the piston cylinder 23 is, may be determined according to the actual situation, and the present disclosure is not particularly limited.
Optionally, the frame body 1 may further be provided with a screw cap, which completely covers the plate feeding conveying mechanism 2, the rotation deviation correcting mechanism 10, the vision positioning system 16, the displacement carrying platform 12 and the printing platform 14, so as to avoid the influence of the external environment on the jet printing process; of course, the screw cap may be coupled to the frame body 1 by means of a hydraulic support rod, thereby achieving the above-mentioned objects.
Optionally, the bottom end of the track support 22 is provided with an installation plate 27 fixedly connected with the frame body 1; the mounting plate 27 is also provided with a piston cylinder position adjusting plate 28 for fixedly connecting the other end of the piston cylinder 23.
As can be seen from the description of fig. 3 to fig. 7, a mounting plate 27 is arranged at the bottom end of the track support 22, a piston cylinder position adjusting plate 28 is fixed on the mounting plate 27, and the other end of the piston cylinder 23 is fixed on the piston cylinder position adjusting plate 28; because the positions of the track bracket 22, the mounting plate 27 and the piston cylinder position adjusting plate 28 are relatively fixed; thus, one end of the piston cylinder 23 is fixed to the transfer rail 21, and the other end of the piston cylinder 23 is fixed relative to the rail holder 22. In this way, the piston cylinder 23 can drive the transfer rail 21 to rotate relative to the rail bracket 22 by using the rail bracket 22 as a fixed point, thereby realizing the above-mentioned functions.
Further, the relative position of the piston cylinder 23 can be adjusted by the piston cylinder position adjustment plate 28; that is, the relative position of the piston cylinder 23 can be adjusted by mounting the piston cylinder position adjusting plate 28 at different positions of the rail bracket 22 while the position of the piston cylinder 23 with respect to the piston cylinder position adjusting plate 28 is unchanged; similarly, the position of the piston cylinder position adjustment plate 28 relative to the rail bracket 22 is unchanged, while the position of the piston cylinder 23 relative to the piston cylinder position adjustment plate 28 is adjusted, so that a change in the relative position of the piston cylinder 23 can also be achieved. Of course, it is also possible to adjust the relative position of the piston cylinder position adjustment plate 28 with respect to the rail bracket 22 and the position of the piston cylinder 23 with respect to the piston cylinder position adjustment plate 28 at the same time to achieve a change in the position of the piston cylinder 23. Whatever the manner, it is sufficient if it is capable of effecting a change in the position of the piston cylinder 23 to achieve the function described above.
Preferably, the rail bracket 22 is vertically disposed; i.e. in the initial state, the transfer rail 21 is at right angles to the rail holder 22; further, the sensor 25 is provided at a position close to the piston cylinder 23; that is, since the pcb is transferred from the side close to the piston cylinder 23, the pcb is first contacted with the transfer rail 21 close to the hinge point and then transferred to the end far from the hinge point, so that the sensor 25 is disposed close to the hinge point to facilitate the detection of the pcb and to prevent the inaccurate detection. Of course, the sensor 25 is connected to the motor 26 for controlling the conveyor 24, so that when the printed circuit board is detected, the motor 26 is started to operate, and the conveyor 24 is driven to operate, thereby completing the above-mentioned actions.
Optionally, the slide rail is a linear slide rail; the linear slide rail comprises a first slide rail, a second slide rail and a connecting plate for connecting the first slide rail and the second slide rail, and the first slide rail moving on the first slide rail and the second slide rail moving on the second slide rail are both fixed by a positioning plate 124; the first lifting platform 121 and the second lifting platform 122 are both arranged on a slider connecting plate, so that the first lifting platform 121 and the second lifting platform 122 can synchronously reciprocate; the nozzle of the jet printing system 9 is arranged at the moving tail end of the first lifting carrying platform 121; the plate-out conveying mechanism 13 is disposed at the moving end of the second elevating stage 122.
That is, after the pcb is positioned by the rotation deviation rectifying mechanism 10 and/or the vision positioning system 16, the first elevating carrier 121 transfers the pcb on the rotation deviation rectifying platform 6 to the moving end of the first elevating carrier 121, and the nozzle of the jet printing system 9 is disposed at the moving end of the first elevating carrier 121, so that the jet printing system 9 can perform the character jet printing process on the pcb on the first elevating carrier 121; after the character jet printing process is completed, the printed circuit board is sent to the second elevating stage 122, and is then transported to the moving end of the second elevating stage 122 by the second elevating stage 122, and because the board discharging transport mechanism 13 is arranged at the moving end of the second elevating stage 122, the printed circuit board is sent to the next process by the board discharging transport mechanism 13.
Specifically, the first elevating stage 121 may be provided with three positions of different heights; when the first elevating stage 121 descends to the lowest position, the upper surface of the air suction platform 123 of the first elevating stage 121 is lower than the rotary deviation rectifying platform 6; here, it is preferable that the rotation deviation rectifying platform 6 is at the same height as the printing platform 14 of the inkjet printing system 9, that is, when the first elevating stage 121 descends to the lowest position, the upper surface of the air suction platform 123 of the first elevating stage 121 is lower than the rotation deviation rectifying platform 6 and the printing platform 14. We refer to the height at this time as the first height.
When the first lifting platform 121 is lifted to the highest position, the upper surface of the air suction platform 123 of the first lifting platform 121 is higher than the rotary deviation rectifying platform 6 and the printing platform 14; we refer to the height at this time as the second height.
In addition, the upper surface of the air suction platform 123 of the first lifting and lowering stage 121 can be horizontal to the rotary deviation rectifying platform 6 and the printing platform 14; we call the height at this time the third height.
Similarly, the second elevating stage 122 can be provided with two positions with different heights, and when the second elevating stage 122 is lowered to the lowest position, the upper surface of the suction platform 123 of the second elevating stage 122 is lower than the printing platform 14; here, it is preferable that the printing platform 14 and the upper surface of the board discharging conveying mechanism 13 are at the same height, that is, the upper surface of the air suction platform 123 of the second elevating stage 122 is lower than the upper surfaces of the printing platform 14 and the board discharging conveying mechanism 13; and at this time, the height of the air suction platform 123 of the second elevating stage 122 is the same as the first height, that is, the air suction platform 123 of the second elevating stage 122 is at the first height at this time.
When the air suction platform 123 of the second elevating platform 122 ascends to the highest position, the upper surface of the air suction platform 123 of the second elevating platform 122 is higher than the upper surfaces of the printing platform 14 and the plate discharging conveying mechanism 13; and at this time, the height of the air suction platform 123 of the second elevating stage 122 is the same as the second height, that is, the air suction platform 123 of the second elevating stage 122 is at the second height at this time.
The first lifting carrying platform 121 descends to a first height and moves to a position right below the printed circuit board of the rotary deviation rectifying platform 6; then the first lifting carrying platform 121 is lifted to a third height, and at this time, the air suction platform 123 of the first lifting carrying platform 121 is horizontal to the rotation correcting platform 6; then, the air suction platform 123 of the first lifting carrying platform 121 starts to suck air so as to suck the printed circuit board; meanwhile, the rotating deviation rectifying platform 6 stops air suction and loosens the printed circuit board; thus, the printed circuit board is fixed on the suction platform 123 of the elevating carrier 121; when the suction platform 123 of the lifting stage 121 is raised to the second height, the lifting stage 121 moves to the end of the first slide rail. Preferably, the printing platform 14 is disposed at the end of the first slide rail, that is, the printing platform 14 is disposed below the nozzle of the jet printing system 9, so that after the first slide rail is moved to the end of the first slide rail, the first lifting and lowering stage 121 is lowered to the third height, the printed circuit board on the air suction stage 123 of the lifting and lowering stage 121 is located on the printing platform 14, and at this time, the nozzle can perform character jet printing on the printed circuit board on the printing platform 14.
After the jet printing process is finished, the suction of the first lifting carrying platform 121 is closed, and the first lifting carrying platform is lowered to a first height; at this time, the second lifting stage 122 is also at the first height; then the first lifting platform 121 moves to the position of the rotation deviation rectifying platform 6, and the second lifting platform 122 also moves to the position of the printing platform 14 of the jet printing system 9 synchronously; then, the first elevating stage 121 repeats the above operations, and transfers the positioned printed circuit board to the position of the printing platform 14 of the inkjet printing system 9, and the second elevating stage 122 transfers the printed circuit board on which the character inkjet printing is completed to the board discharging transport mechanism 13. Therefore, the full-automatic process of feeding, positioning, deviation correction, jet printing and discharging can be realized.
Here, in the process that the positioned printed circuit board is transferred to the printing platform 14 of the jet printing system 9 by the first lifting carrier 121 to perform character jet printing, the board feeding and conveying mechanism 2 conveys the next printed circuit board to the rotary deviation rectifying platform 6 to perform the positioning step; therefore, a large amount of processing time before character jet printing is saved, and the jet printing efficiency is improved to a great extent.
