Claims

1. A hand tool printing device, comprising: A base; A slide rail assembly, located on top of the base, includes a slide rail and a slider, the slider sliding movably along the slide rail; a positioning assembly, comprising a servo motor with a central shaft and a positioning seat, the positioning seat being connected to the top of the central shaft, the servo motor driving and controlling the rotation of the central shaft and causing the positioning seat to rotate together; a stamping assembly, located on top of the slider and moving with the slider's displacement, the stamping assembly including a replaceable stamping part, a telescopic arm, and a lifting member, the lifting member being located on top of the slider and connected to one end of the telescopic arm, the other end of the telescopic arm being connected to the stamping part, the lifting of the lifting member and the extension / retraction of the telescopic arm controlling the stamping part to move closer to or away from the positioning assembly; A control group is provided, which contains a control module. The control module is electrically connected to the slide rail group, the servo motor and the stamp group. The control module controls the movement of the slider along the slide rail, the rotation of the servo motor, the lifting of the lifting component and the extension and retraction of the telescopic arm.

2. A method for printing on a hand tool, comprising the following steps: Preliminary step: placing a hand tool on a positioning group located on a base, the positioning group having a servo motor with a central shaft and a positioning seat, the hand tool being fitted onto the positioning seat; Control step: activating a control group, the control group further comprising a control module, the control module controlling the movement path of a slide rail group, the lifting height of a steel stamp group, and the extension distance of a telescopic arm of the steel stamp group; First positioning step: adjusting the slide rail group using the control module, causing a slider of the slide rail group to move along a slide rail, and causing the steel stamp group located at the top of the slider to move together to correspond to the hand tool; Second positioning step: adjusting the steel stamp group using the control module, causing a lifting component of the steel stamp group to move up and down, and causing the telescopic arm to move up and down to correspond to the hand tool; Third positioning step: adjusting the telescopic arm to extend and retract towards the hand tool using the control module, causing a steel stamp component at one end of the telescopic arm to abut against the surface of the hand tool; Printing Steps: After the above steps are adjusted and set, the control module starts the operation of the servo motor to rotate the shaft rod. The rotation of the shaft rod drives the positioning seat on which the hand tool is mounted to rotate. At the same time, the control module also controls the slider to move repeatedly along the slide rail. The repeated displacement of the slider also drives the steel stamp group to move repeatedly. In conjunction with the servo motor, the rotation of the hand tool is indirectly driven, so that the steel stamp is repeatedly printed on the surface of the hand tool. Removal Steps: After the steel stamp is printed on the surface of the hand tool, the control module controls the slider to stop moving and the servo motor to stop running, and removes the printed hand tool from the positioning seat.

3. The hand tool printing method as described in claim 2, wherein the positioning seat further has a set segment, and any two corresponding outer surfaces of the set segment are respectively recessed with a positioning groove, the positioning groove accommodating a positioning ball, the positioning ball engaging with a plurality of positioning holes of the hand tool.

4. The hand tool printing method as described in claim 3, further comprising a sensor adjacent to the positioning group, the sensor having a sensing module disposed therein, the sensing module being electrically connected to the control module, the sensing module detecting the position change of each positioning ball as the hand tool rotates during the printing process.

5. The hand tool printing method as described in claim 4, wherein the control group has a screen display, the screen display is electrically connected to the control module and the sensing module, and the control module further has a built-in setting unit, the screen display displays the interface of the setting unit and sets or adjusts the sliding position and speed of the slider on the slide rail, the rotation speed of the servo motor, the lifting position and speed of the lifting member and the extension length of the telescopic arm.

6. The hand tool printing method as described in claim 2, wherein the lifting member further comprises a lifting groove and a lifting seat, the lifting seat having a pneumatic cylinder, one end of the pneumatic cylinder of the lifting seat being connected to the telescopic arm, the other end of the lifting seat being controlled by the control module to slide up and down in the lifting groove, and the pneumatic cylinder being controlled by the control module to extend and retract the telescopic arm.
