[0036] This embodiment discloses an assembly information writing device and an assembly information writing method based on the device, which can be used in but not limited to the field of shipbuilding. Figure 1 and Figure 2 As shown, the assembly information writing device includes a cutting machine, a base 1 and an inkjet head 2. The cutting machine is provided with a track assembly, a driving device and a control device, the base 1 is connected to the track assembly and can move along the track assembly, and the inkjet head 2 is connected to the base 1. The control device can control the action of the driving device, so that the base 1 drives the inkjet head 2 to move along the track assembly to write the assembly information at a set position.

[0037] In this embodiment, the control device can be a centralized or distributed controller. For example, the controller can be a single single-chip microcomputer or a distributed plurality of single-chip microcomputers. The single-chip microcomputer can run a control program to control the driving device to realize its function.

[0038] The driving device may be, but is not limited to, a motor and a hydraulic pump. Any device in the prior art that can drive the inkjet head 2 to move along the track assembly can be used.

[0039] The assembly information writing method based on the above device is: the inkjet head 2 of the cutting device is moved to the position to be written, and the driving device drives the inkjet head 2 to move along the writing of the assembly information and controls the opening and closing of the inkjet head 2 at the same time, so as to write the assembly information on the material 4 to be written (such as a steel plate) to prepare for the subsequent material cutting. The assembly information may include but is not limited to the name of the parts to be installed, the number of parts, the installation method, etc.

[0040] An inkjet head 2 is installed on the existing cutting machine, and the assembly information is written on the material 4 to be written using the inkjet head 2, which solves the problems of blurred handwriting, missing information or miswriting that may occur in manual writing. The accuracy and consistency of the assembly information writing are higher, which greatly improves the production efficiency and overall quality, reduces production delays and cost increases caused by errors in the writing of assembly information; reduces the workload of operators, reduces labor intensity, improves the working environment, and makes the production process smoother; reduces production costs, especially in a large-scale production environment, the effect of reducing costs is more obvious.

[0041] The specific structure of the track assembly is not limited, as long as it can support the movement of the base 1. In this embodiment, the track assembly includes two guide posts 3. Two mounting through holes are provided on the base 1, and each guide post 3 is inserted into one mounting through hole. After assembly, the two guide posts 3 form an included angle of a set angle.

[0042] In order to avoid mutual interference between the two guide columns 3, the two installation through holes are spaced apart in the vertical direction, and the two guide columns 3 are also spaced apart accordingly. The specific shape and setting position of the two installation through holes are not limited, as long as the height of the base 1 in the vertical direction is greater than the sum of the diameters of the two guide columns 3, two mutually separated installation through holes can be drilled on the side wall of the base 1.

[0043] The specific value of the angle between the two guide posts 3 is not limited, as long as the inkjet head 2 moving along the guide posts 3 can reach all positions on the material 4 to be written. In this embodiment, the two guide posts 3 are perpendicular to each other. Any position on the material 4 to be written can be represented by a two-dimensional coordinate (x, y). One of the two guide posts 3 is parallel to the x direction and the other is parallel to the y direction. The inkjet head 2 can be moved according to the two-dimensional coordinate (x, y), which is more convenient to use and more accurate in writing the assembly information.

[0044] The specific method of moving the base 1 is not limited, as long as the inkjet head 2 can be sent to the position to be written and can move along the handwriting of the assembly information. In this embodiment, an external thread is provided on the outer peripheral surface of the guide column 3, and an internal thread that matches the external thread is provided on the inner wall surface of the mounting through hole. When the guide column 3 is inserted into the mounting through hole, the external thread and the internal thread match. The end of the guide column 3 is connected to the output end of the motor, and when the output end of the motor rotates, it can drive the guide column 3 to rotate around its own axis. When the guide column 3 rotates around its own axis, the combined structure of the external thread and the internal thread drives the base 1 to move along the guide column 3, Figure 1 The middle arrow indicates the moving direction of the base 1.

[0045] Writing assembly information includes the following steps:

[0046] Step S1, the control device receives the content to be written, which may be but is not limited to Chinese characters, numbers, letters and characters. In order to facilitate writing, the content to be written is displayed as much as possible with short horizontal and vertical lines. When all the content to be written is distributed in different positions on the material to be written 4, all the content to be written is divided into N writing areas, P1, P2, P3...PN, where N is a natural number.

[0047] Step S2: The driving device moves the inkjet head 2 to the writing position to prepare for writing.

[0048] Step S3, the driving device drives the inkjet head 2 to move along the writing of the assembly information, and turns on the inkjet head 2 when passing the position where writing is required, and the inkjet head 2 sprays ink onto the material 4 to be written to form a trace; the inkjet head 2 is turned off when passing the blank position to avoid miswriting.

[0049] Step S4: After completing a writing area, N=N-1, determine whether the current N is 0, if so, the step ends, otherwise go to step S2.

[0050] Based on the above, the method of moving from the previous writing area to the next writing area is:

[0051] Subtract the first coordinate A1 of the writing end point of the previous writing area from the first coordinate B1 of the writing starting point of the next writing area to obtain C1; subtract the second coordinate A2 of the writing end point of the previous writing area from the second coordinate B2 of the writing starting point of the next writing area to obtain C2; the inkjet head 2 moves from the writing end point of the previous writing area to the writing starting point of the next writing area according to the values ​​of C1 and C2.

[0052] C1 and C2 may be positive or negative. When they are positive, the base 1 moves the inkjet head 2 toward one end of the guide column 3. When they are negative, the base 1 moves the inkjet head 2 toward the other end of the guide column 3, ensuring that the inkjet head 2 can accurately move to the target position.

[0053] The specific path for moving from the previous writing area to the next writing area is not limited, and the base 1 can directly move the inkjet head 2 obliquely to the position, which has higher moving efficiency, but is inconvenient to control. In this embodiment, the inkjet head 2 first moves along the first coordinate direction (one of the x direction and the y direction) by a distance C1, and then moves along the second coordinate direction (the other of the x direction and the y direction) by a distance C2; ​​or, the inkjet head 2 first moves along the second coordinate direction by a distance C2, and then moves along the first coordinate direction by a distance C1.

[0054] Similar to a right triangle, the previous writing area and the next writing area are located at the endpoints of the two acute angles respectively. "Directly moving diagonally into position" is moving along the hypotenuse; decomposing the diagonal path into numerical lines and horizontal lines at both ends is moving along the two right-angled sides respectively. The control method is simple and easy to use.

[0055] Note that the above are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention is described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
