BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0017] The following is a detailed description of an embodiment of the utility model in conjunction with the accompanying drawings. This embodiment is implemented on the premise of the technical solution of the utility model, and a detailed implementation method and a specific working process are given, but the protection scope of the utility model is not limited to the following embodiment.

[0018] like Figure 1 As shown, the fully automatic profile marking device described in the utility model includes a fixed frame 1 and a movable frame 2 arranged on the profile M to be marked, a pull-wire displacement sensor 3 is installed on the fixed frame 1, the movable frame 2 is slidably connected to the mounting groove of the surface of the profile M to be marked, movable wheels 4 connected to the adjacent two side walls of the surface of the profile M to be marked are installed on both sides of the bottom of the movable frame 2, a pull-wire fixture 5 connected to the pull wire L of the pull-wire displacement sensor 3 is installed on the top of the movable frame 2, a support arm 6 extending toward the front side is also installed on the movable frame 2, a push-pull electromagnet 7 is installed on the support arm 6, a push rod of the push-pull electromagnet 7 is connected to a seal 8 located above the surface of the profile M to be marked, wherein the signal output end of the pull-wire displacement sensor 3 is electrically connected to the signal input end of the PLC, and the control output end of the PLC is electrically connected to the control input end of the push-pull electromagnet 7.

[0019] The moving wheel 4 includes a driving wheel and a driven wheel, wherein the driving wheel is driven by a DC motor or a stepping motor 8 mounted on the top surface of the moving frame 2. The stepping motor 8 uses an electronic circuit to convert DC power into time-sharing power supply and control the current with multi-phase timing. Therefore, when the marking accuracy requirement is not high, the wire-drawing displacement sensor 3 can be omitted, and the marking distance can be controlled only by the stepping motor 8. The wire-drawing displacement sensor 3 can also be replaced by a laser rangefinder.

[0020] The axle of the moving wheel 4 is installed in the adjustment groove 9 on the moving frame 2, and each adjustment groove 9 is a transverse long hole perpendicular to the pull rope L of the pull rope displacement sensor 3. By adjusting the installation position of the axle of the moving wheel 4 in the adjustment groove 9, the moving wheel 4 is closely attached to the side walls of the profile M on both sides of the surface to be scribed, so that the moving frame 2 can adapt to profiles of different widths and expand its application range. Usually, the moving wheel 4 uses a solid rubber wheel with a wheel surface width greater than the width of the installation groove of the profile M to ensure that the moving wheel 4 is closely attached to the side walls of the profile M.

[0021] The pattern on the above-mentioned seal 8 can be a straight line, a broken line, a ring or other special-shaped shapes designed as required. Each seal 8 is movably connected to the push rod of the push-pull electromagnet 7 by plug-in, screw connection, etc. Different seals 8 can be replaced as needed, which provides convenience for the later assembly of different parts and avoids human errors.

[0022] When in use, install the fixed frame 1 on the surface of the profile M to be marked, adjust the width of the moving wheel 4, and install the moving frame 2 on the same side of the profile M, so that the seal 8 is located above the surface of the profile M to be marked, and the moving wheels 4 on both sides are close to the side walls of the profile M on the adjacent sides of the surface to be marked. Afterwards, fix the pull rope L of the pull rope displacement sensor 3 on the pull rope fixture 5, and then start the motor. When the moving frame 2 reaches the predetermined position, the pull rope displacement sensor 3 sends a signal to the PLC, and the PLC sends a power-on signal to the control end of the push-pull electromagnet 7, and the push rod extends, so that the seal 8 is stamped on the profile M.

[0023] When a part with a position requirement relative to one end of the profile needs to be assembled on the profile, it is necessary to precisely mark the profile and then use the marked line as the assembly reference.

[0024] It should be noted that, in the description of the present invention, terms indicating orientation or positional relationships, such as "front", "rear", "left", "right", "vertical", "horizontal", "inside", "outside", etc., are based on the orientation or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
