[0035] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments.
[0036] Please see Figures 1 to 5The utility model discloses a kind of multi-material positioning adjustment mechanisms, mainly including first drive module 1, upper suction disc 2, adsorption platform 3 and CCD module 4, wherein, CCD module 4 is used to detect the position of multiple materials, adsorption platform 3 is located below upper suction disc 2, adsorption platform 3 includes multiple lower suction disc 31, adsorption platform 3 is connected with driver 5 and moves up and down under the driving of driver 5, lower suction disc 31 is used to adsorb the lower surface of corresponding one material, upper suction disc 2 is used to adsorb the upper surface of material, first drive module 1 is connected with upper suction disc 2 and is signal connected with CCD module 4, first drive module 1 is used to move to calibrate the position of material by driving upper suction disc 2 according to the detection result of CCD module 4.
[0037] Specifically, the multi-material positioning adjustment mechanism of the present scheme can follow the following working steps:
[0038] Step (1): by artificial feeding or transport guide rail 7, the carrier with multiple materials is moved to the upper of adsorption platform 3, multiple lower suction disc 31 is driven to rise by driver 5, lower suction disc 31 will be lifted up and adsorb corresponding one material, until multiple materials are all jacked up to the image taking position, the position of material is detected by CCD module 4;
[0039] Step (2): upper suction disc 2 moves to the upper of the material at the required calibration position under the driving of first drive module 1, multiple lower suction disc 31 continues to rise with the driving of driver 5 and is adsorbed by upper suction disc 2, then lower suction disc 31 releases the material and moves down under the driving of driver 5, immediately, first drive module 1 drives upper suction disc 2 to move according to the detection result of CCD module 4, to calibrate the position of corresponding material, after that, lower suction disc 31 rises again under the driving of driver 5 and adsorbs the material, finally, upper suction disc 2 releases the material and the material whose position has been calibrated is moved down by lower suction disc 31, at this time, the position of single material has been calibrated;
[0040] Step (3): other materials repeat step (2), until the position of all materials is calibrated, then multiple materials can be specified to work, for example, when printing execution mechanism prints multiple materials, multiple lower suction disc 31 moves down under the driving of driver 5, so that multiple materials are put back to the carrier.
[0041] In summary, the present scheme can automatically realize the position calibration of multiple materials, to meet the production needs of subsequent efficient and high-quality printing work of multiple materials. In addition, preferably, after the position of all materials is calibrated, whether the position of all materials is correct can be repeatedly confirmed by CCD module 4, if not, the position of corresponding material is calibrated again, by such design, the high position accuracy of multiple materials in subsequent printing can be further ensured, thereby being beneficial to further improve the printing quality of multiple materials.
[0042] This section provides further explanation that in step (1) above, CCD module 4 can either collect the position of all materials one by one in advance, or it can collect the position information of only one material and then immediately execute step (2). If CCD module 4 is in the latter case, it is equivalent to CCD module 4 collecting the position information of another material before executing step (2) after calibrating the position of one material and before calibrating the other material. When CCD module 4 collects the position information of the material, the multiple materials adsorbed by the multiple lower suction cups 31 should be at a height (i.e., the imaging position) that can be imaged by CCD module 4.
[0043] In this embodiment, the multi-material positioning adjustment mechanism further includes a second drive module 6, which is connected to the adsorption platform 3. The second drive module 6 is used to drive the adsorption platform 3 to move. Preferably, before calibrating the position of the material (i.e., before performing the above step (1), the relative position of the carrier and the actuator on the adsorption platform 3 needs to be pre-calibrated by the second drive module 6. Taking the printing device as an example, the actuator includes a steel mesh, so the second drive module 6 can calibrate the position of the carrier relative to the steel mesh by driving the carrier on the adsorption platform 3 to move along the X direction, Y direction or rotation direction R.
[0044] In this embodiment, please refer to Figure 5 The material calibration position includes the X direction, Y direction, and rotation direction R with the vertical axis as the rotation axis. Specifically, in this embodiment, preferably only the first driving module 1 drives the material adsorbed by the upper suction cup 2 to complete the position calibration of the material in the X direction, Y direction, and rotation direction R. In other words, the first driving module 1 under this design specifically includes a Y-axis module 11, an X-axis module 12, and a rotary motor 13 connected in sequence. The upper suction cup 2 is connected to the rotary motor 13. The Y-axis module 11 is used to drive the X-axis module 12, the rotary motor 13, and the upper suction cup 2 to move together along the Y direction to realize the calibration position of the material adsorbed by the upper suction cup 2 in the Y direction. The X-axis module 12 is used to drive the rotary motor 13 and the upper suction cup 2 to move together along the X direction to realize the calibration position of the material adsorbed by the upper suction cup 2 in the X direction. The rotary motor 13 is used to drive the upper suction cup 2 to rotate around the rotation direction R to realize the calibration position of the material adsorbed by the upper suction cup 2 in the rotation direction R.
[0045] In other embodiments, the position calibration of the material in the X direction, the Y direction and the rotation direction R can also be assigned to the first driving module 1 and the second driving module 6 to be completed together, for example, the first driving module 1 is not provided with the X-axis module 12, at this time, the first driving module 1 only calibrates the position of the material in the Y direction and the rotation direction R, the second driving module 6 can move the carrier on the adsorption platform 3 in the X direction and then receive the material of the upper suction plate 2 by the lower suction plate 31 to calibrate the relative position of the material and the carrier in the X direction, at this time, the adjustment position of the material in the X direction, the Y direction and the rotation direction R can also be realized and finally the purpose of being placed on the carrier with high precision can be achieved. It is supplemented here that if the calibration of the material needs to use the second driving module 6, the carrier on the adsorption platform 3 needs to be reset to the initial position (i.e., the carrier is reset to the position aligned with the steel mesh) before the position calibration of each material (i.e., before step (2) is performed). As can be seen, the second driving module 6 under this design not only has the function of calibrating the relative position of the carrier and the steel mesh, but also has the function of assisting in calibrating the relative position of the material and the carrier.
[0046] Please refer to Figure 4 and Figure 5 , the CCD module 4 is preferably connected to the X-axis module 12, that is, the CCD module 4 shares the Y-axis module 11 and the X-axis module 12 with the rotation motor 13, so that the CCD module 4 can move together with the rotation motor 13 in the X direction or the Y direction, so that the CCD module 4 can make a two-axis planar movement to be able to complete the function of collecting position information of multiple materials. In other embodiments, the CCD module 4 can also be driven by another separate driver to realize the function of collecting position information of multiple materials.
[0047] Please refer to Figure 5 again, the first driving module 1 further comprises a lifting actuator 14, the lifting actuator 14 can be connected between the rotation motor 13 and the X-axis module 12 (i.e., the lifting actuator 14 drives the rotation motor 13 and the upper suction plate 2 to move up and down together), or the lifting actuator 14 can be connected between the rotation motor 13 and the upper suction plate 2 (i.e., the rotation motor 13 drives the lifting actuator 14 and the upper suction plate 2 to rotate together), the lifting actuator 14 is preferably a low-cost air cylinder, and the lifting actuator 14 is used to drive the upper suction plate 2 to move in the vertical direction. Preferably, when the upper suction plate 2 adsorbs the material and calibrates the position of the material under the driving of the first driving module 1, the lifting actuator 14 always drives the upper suction plate 2 to be in a lower position, and when the positions of all materials are calibrated, the upper suction plate 2 is lifted and reset under the driving of the lifting actuator 14.
[0048] The multi-material positioning adjustment mechanism of this embodiment is preferably applied to a printing apparatus. In the printing apparatus, the material whose position needs to be calibrated is equivalent to a substrate. The printing apparatus includes the multi-material positioning adjustment mechanism described above; please refer to [further details omitted]. Figure 1 and Figure 2 The printing apparatus also includes a printing execution mechanism 8 and a lifting mechanism 9. The printing execution mechanism 8 is located above the adsorption platform 3. The printing execution mechanism 8 may include a ball-planting mechanism for implanting solder balls or a squeegee for scraping solder paste onto the substrate. The lifting mechanism 9 may be directly or indirectly connected to the adsorption platform 3 and used to drive the adsorption platform 3 to move vertically, so that the carrier and multiple substrates on the adsorption platform 3 can move upward toward the printing execution mechanism 8 and allow the printing execution mechanism 8 to perform printing operations on multiple substrates. The lifting mechanism 9 may also be disposed on the printing execution mechanism 8 and used to drive the printing execution mechanism 8 to move vertically, so that the printing execution mechanism 8 can move downward toward multiple substrates and perform printing operations on multiple substrates. Of course, before the printing execution mechanism 8 prints on the substrate, the upper suction cup 2 and the CCD module 4 need to be retracted outward under the drive of the first driving module 1 to ensure that the printing execution mechanism 8 can perform printing operations on the substrate in the vertical direction.
[0049] Please refer to them again. Figure 1 and Figure 2 The printing apparatus also includes a transport rail 7, which is used to drive a carrier carrying multiple materials to move above the adsorption platform 3 or to move the carrier located above the adsorption platform 3 outward, so as to realize automatic loading and unloading of the carrier and improve the printing efficiency of multiple materials.
[0050] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
