The invention discloses a method for automatically spray painting three-dimensional patterns on a vehicle body surface, and belongs to the field of vehicle digital design and manufacturing. The method for automatically spray painting the three-dimensional patterns on the vehicle body surface includes the steps of setting up a vehicle outer covering piece model through three-dimensional design software, dispersing the vehicle outer covering piece model into a triangular mesh model, thereby setting up the mapping relation between the triangular mesh model and a planar parameter region, inversely mapping points, corresponding to pattern pixel points, in the planar parameter region onto a vehicle body three-dimensional model based on the mapping relation, setting up the corresponding relation between the pattern pixel points and vehicle body three-dimensional points, storing color information of pixels, generating spray paint paths on the vehicle body three-dimensional model, adjusting the spray paint colors of the patterns according to the pixel color information corresponding to the path points, and then completing the process of automatically spray painting the three-dimensional patterns on the vehicle body surface by driving a spray painting robot. Various individualized patterns are automatically spray painted on the vehicle body surface under the control of a computer according to the spray painting paths generated through the method, and the principle is simple, the spray painting is even, the patterns are vivid, and the pattern spray painting efficiency is effectively improved.

The number tubes use an inkjet device. The number tubes in the storage box fall one by one through the discharge channel and are arranged in an orderly manner. After the printing is completed, they are pushed out by the first push block, and the upper number tubes roll down to continue the inkjet work. Manually replace the number tube to improve the printing efficiency.

The invention discloses a solar water heater water tank clamping tool. The tool comprises two clamping parts oppositely arranged, and transmission devices and swing arms connected with the clamping parts; free ends of the two swing arms are connected to form a U shape; the clamping parts include clamping jaws and chucks; the transmission devices include rotating shafts, cams and belt drives; the chucks are crossed; U-shaped grooves are respectively formed in four extension arms of the chucks; the clamping jaws are hinged with the U-shaped grooves in the chucks; the rotating shafts are arranged at the middle parts of the chucks; one ends of the rotating shafts are vertically connected with the chucks, and the other ends are vertically connected with the inner sides of one ends of the swing arms; the rotating shafts are coated with the cams and the synchronous belt drives; motor control the rotation of the belt drives and the cams; one ends of the clamping jaws are contacted with the cams; and springs are arranged between the clamping jaws and the inner sides of the chucks. The clamping tool is simple in structure, improves the working efficiency, guarantees the trademark image inkjet beauty, relieves the labor intensity, and is convenient for use.

The invention discloses an ink-jet head control panel of an ink-jet printer and a method for transmission of printable data. One end of the ink-jet head control panel is connected with a master control panel and used for receiving serial printed data after the data are processed and the other end of the ink-jet head control panel is connected with ink-jet heads and used for sending the printable data with no error after verification to the ink-jet heads. The ink-jet head control panel mainly comprises an FPGA, a DES, a CAN chip sending end (PHY), a power module and a peripheral control interface unit. The ink-jet head control panel is characterized in that an SDRAM is additionally arranged on the ink-jet head control panel and connected with the FPGA, bi-directional data transmission can be conducted between the SDRAM and the FPGA, and the SDRAM is used for storing the printable data with no error after the data are verified through the FPGA and finally outputting the printable data with no error after verification to at least one ink-jet head for printing. The SDRAM is provided with multiple zones, the number of the zones is identical to that of the ink-jet heads, and the printable data with no error after verification needed by each ink-jet head are stored in the corresponding zone. In the printing process, the stored printable data with no error after verification are sent to the corresponding ink-jet head for image-text printing by the SDRAM, the phenomenon that the data are transmitted to the ink-jet heads mistakenly after printing operation is started can be avoided, the functions of the ink-jet head control panel are completed, and the ink-jetting efficiency is improved.

The invention provides a piezoelectric inkjet printing spray head structure preventing ink backflow. An ink supply channel is connected with an ink box. Due to capillary force action, the ink supply channel, a flow limiting part, a pressure generation cavity and a flow guide part are full of ink sequentially, and the ink reaches a nozzle. An upper electrode, piezoelectric ceramics, a lower electrode and a vibration plate form a driving element, when the upper electrode and the lower electrode are electrified simultaneously, the piezoelectric ceramics deform due to an inverse piezoelectric effect, then the vibration plate is driven to deform, the vibration plate deforms to extrude the ink in the pressure generation cavity, the flow limiting part and the flow guide part prevent the ink fromflowing back to the ink supply channel, and the ink is sprayed out from the nozzle. The piezoelectric ceramics are used for the piezoelectric inkjet printing spray head structure, the driving elementgenerate driving force, removing machining is conducted on the base part corresponding to the pressure generation cavity, and the driving element is in a suspension state and is located in the e pressure generation cavity. The piezoelectric inkjet printing spray head structure is simple in manufacture process, low in cost and good in process repeatability and has an ink backflow prevention effect.
