Description

Technical Field

[0001] This invention belongs to the field of printing apparatus, and particularly relates to a hand tool printing apparatus and method. Background Technology

[0002] Existing hand tool printing devices such as Figure 9 As shown, the device includes a plurality of rollers and a stamping block. The rollers are close to each other to form a printing space. A hand tool is placed in the printing space and rotates with the rollers. The stamping block applies pressure from above to create an imprint. However, existing hand tool printing devices have the following shortcomings: First: Because there is no fixed part between the rollers and the hand tool to prevent the hand tool from moving, the hand tool may shift as the rollers roll, resulting in skewed and inaccurate imprints. Figure 9 As shown; Second: Because the stamping block applies pressure from above in a single operation, the hand tool may deform due to its hollow interior and insufficient support caused by excessive pressure. Figure 10 As shown; In conclusion, in the printing industry of hand tools, traditional methods not only lead to increased material costs due to replacement and reprinting, but also cause wear and tear on the parts of the equipment, which in turn reduces production efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a positioning assembly that allows the hand tool to be fixed in position and not to shift during the printing process. At the same time, the positioning base provides support for the hand tool, making it less prone to deformation during printing. This improves upon the shortcomings of the prior art, such as difficulty in positioning and easy deformation.

[0004] To achieve the above objectives, the present invention provides a hand tool printing device, comprising: a base; a slide rail assembly disposed on the top of the base, the slide rail assembly having a slide rail and a slider, the slider being movably mounted on the slide rail; a positioning assembly comprising a servo motor having 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; and a stamping assembly disposed on the top of the slider and moving with the displacement of the slider, the stamping assembly having a movable replacement function. The system comprises a steel stamp, a telescopic arm, and a lifting component. The lifting component is located on top of the slider and is connected to one end of the telescopic arm. The other end of the telescopic arm is connected to the steel stamp. The lifting and lowering of the lifting component and the extension and retraction of the telescopic arm control the steel stamp to move closer to or away from the positioning group. A control group is also included, which contains a control module. The control module is electrically connected to the slide rail group, the servo motor, and the steel stamp group. The control module controls the slider to move along the slide rail, the rotation of the servo motor, the lifting and lowering of the lifting component, and the extension and retraction of the telescopic arm.

[0005] The present invention also provides a hand tool printing method, which includes 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, and 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: using the control module to adjust the slide rail group, causing a slider of the slide rail group to move along a slide rail, and driving the steel stamp group located at the top of the slider to move together to correspond to the hand tool; Second positioning step: using the control module to adjust the steel stamp group, causing a lifting component of the steel stamp group to move up and down, and driving a telescopic arm to move up and down to correspond to the hand tool; Third... Positioning Step: Using the control module, adjust the telescopic arm to extend and retract towards the hand tool, so that a steel stamp at one end of the telescopic arm abuts against the surface of the hand tool; Printing Step: After the above steps are adjusted and set, use the control module to start 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 assembly to move repeatedly. In conjunction with the servo motor, the rotation of the hand tool is indirectly driven, so that the imprint of the steel stamp can be repeatedly printed on the surface of the hand tool; Removal Step: After the steel stamp is printed on the surface of the hand tool in the above steps, the control module controls the slider to stop moving and the servo motor to stop running, and removes the hand tool that has been printed from the positioning seat.

[0006] Furthermore, the positioning seat further includes a set segment, on which a positioning groove is recessed on any two corresponding outer surfaces. The positioning groove accommodates a positioning ball, which engages with a plurality of positioning holes of the hand tool.

[0007] Furthermore, it further includes a sensor adjacent to the positioning group, the sensor having a sensing module inside, the sensing module being electrically connected to the control module, the sensing module detecting the position changes of each positioning ball as the hand tool rotates during the printing process.

[0008] Furthermore, the control unit has a screen display, which is electrically connected to the control module and the sensing module. The control module also has a built-in setting unit. The screen display shows 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 component, and the extension length of the telescopic arm.

[0009] Furthermore, the lifting component further includes a lifting groove and a lifting seat. The lifting seat has a pneumatic cylinder. One end of the pneumatic cylinder of the lifting seat is connected to the telescopic arm. The other end of the lifting seat is controlled by the control module to slide up and down in the lifting groove, and the pneumatic cylinder is controlled by the control module to extend and retract the telescopic arm.

[0010] Based on the aforementioned technical features defined in this invention, its advantages lie in the fact that the positioning group provides a place for the hand tool to be mounted during the printing process, thereby fixing its position. This avoids the skewing or inaccuracy of the print caused by the rolling of traditional rollers. In addition, the positioning seat also provides support for the hand tool to withstand the pressure caused by the printing block during printing. Overall, it further improves the positioning and deformation problems of the prior art, avoiding the increased printing costs and low efficiency caused by unstable positioning and easy deformation. It is evident that this invention is indeed practical and progressive, and is worthy of promotion in the industry. Attached Figure Description

Detailed Implementation

[0012] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0013] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of the invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0014] The following is a reference to the appendix. Figure 1 To be continued Figure 10 The present invention describes a hand tool printing device, comprising: a base 1; a slide rail assembly 2, which is disposed on the top of the base 1, the slide rail assembly 2 having a slide rail 21 and a slider 22, the slider 22 being movably mounted on the slide rail 21; a positioning assembly 3, which includes a servo motor 31 having a central shaft 311 and a positioning seat 32, the positioning seat 32 being connected to the top of the central shaft 311, the servo motor 31 driving and controlling the rotation of the central shaft 311 and causing the positioning seat 32 to rotate together; and a stamping assembly 4, which is disposed on the top of the slider 22 and moves with the displacement of the slider 22, the stamping assembly 4 having a replaceable stamping element 41. A telescopic arm 42 and a lifting member 43 are provided. The lifting member 43 is located on top of the slider 22 and is connected to one end of the telescopic arm 42. The other end of the telescopic arm 42 is connected to the stamped part 41. The lifting of the lifting member 43 and the extension of the telescopic arm 42 control the stamped part 41 to move closer to and away from the positioning group 3. A control group 5 is provided, which contains a control module 53. The control module 53 is electrically connected to the slide rail group 2, the servo motor 31, and the stamped part 4. The control module 53 controls the movement of the slider 22 along the slide rail 21, the rotation of the servo motor 31, the lifting of the lifting seat 432, and the extension of the telescopic arm 42. Figure 1 , 2 As shown in Figures 3 and 8A.

[0015] The usage steps are as follows, please refer to the following as well. Figure 2 ,3 As shown in Figures 4, 5, 6, 7, 8A, and 8B: Preliminary step S01: Place a hand tool A on a positioning group 3 located on the base 1, and the positioning group 3 has the servo motor 31 of the shaft rod 311 and a positioning seat 32, and the hand tool A is fitted onto the positioning seat 32. Control step S02: Start the control group 5. The control group 5 is further equipped with a control module 53. The control module 53 is used to control the movement path of the slide rail group 2, the lifting height of the steel stamp group 4, and the extension distance of the telescopic arm 42 of the steel stamp group 4. First positioning step S03: Use the control module 53 to adjust the slide rail group 2 so that the slider 22 of the slide rail group 2 moves along the slide rail 21 and corresponds to the hand tool A; Second positioning step S04: Use the control module 53 to adjust the stamp group 4, so that the lifting component 43 of the stamp group 4 moves up and down, and drives the telescopic arm 42 to move up and down to the position corresponding to the hand tool A. Third positioning step S05: Use the control module 53 to adjust the telescopic arm 42 to extend and retract in the direction of the hand tool A, so that the steel stamp 41 at one end of the telescopic arm 42 abuts against the surface of the hand tool. Printing step S06: After the above steps are adjusted and set, the servo motor 31 is started by the control module 53 to rotate the shaft rod 311. The rotation of the shaft rod 311 drives the positioning seat 32 on which the hand tool A is mounted to rotate. At the same time, the control module 53 also controls the slider 22 to move repeatedly along the slide rail 21. The repeated displacement of the slider 22 drives the steel stamp assembly 4 to move repeatedly. In addition, the servo motor 31 indirectly drives the rotation of the hand tool A, so that the imprint of the steel stamp 41 can be repeatedly printed on the surface of the hand tool A. Step S07: After the above steps imprint the mark of the steel stamp 41 onto the surface of the hand tool A, the control module 53 controls the slider 22 to stop moving and the servo motor 31 to stop running, and removes the hand tool A that has been imprinted from the positioning seat 32.

[0016] Based on the above description, the other technical and structural features of the present invention will be further described below. To ensure that all printing positions remain consistent from beginning to end, the positioning seat 32 further has a sleeve segment 321. Any two corresponding outer surfaces of the sleeve segment 321 are respectively recessed with a positioning groove 3211. The positioning groove 3211 accommodates a positioning ball 3212. The positioning ball 3212 engages with the plurality of positioning holes 9 of the hand tool A. Therefore, when the hand tool A is sleeved in the preceding step S01, the plurality of positioning holes 9 of the hand tool A are aligned with each positioning ball 3212 of the sleeve segment 321 to ensure that each positioning hole 9 and each positioning ball 3212 are indeed engaged. In addition, the shape of the sleeve segment 321 itself designed for the hand tool A achieves a double positioning effect. Meanwhile, the fitting section 321 of the positioning seat 32 provides support for the hand tool A, making it less prone to deformation during printing, thus improving the problem of easy deformation in the background technology. Furthermore, the fitting section 321 of the positioning seat 32 addresses the issue of displacement of the hand tool A during printing due to the lack of a fixed position in the background technology. Figure 1 , 2 As shown in 3, 8A, and 8B.

[0017] Meanwhile, a sensor 6 is provided on one side of the base 1, adjacent to the positioning group 3. The sensor 6 contains a sensing module 61, which is electrically connected to the control module 53. During the printing process, the sensing module 61 detects the position changes of each positioning ball 3212 as the hand tool A rotates. In printing step S06, the sensor 6 detects whether the position of the positioning ball 3212 has completely rotated to the corresponding side as the positioning base 32 rotates, thus confirming whether the printing is complete. This integrates the printing process and quality inspection, saving a step. Figure 1 , 2 As shown in 3, 8A, and 8B.

[0018] In addition, to accommodate various sizes of the hand tool A, the lifting component 43 further includes a lifting groove 431 and a lifting seat 432. One end of the lifting seat 432 is connected to the telescopic arm 42, and the other end of the lifting seat 432 is controlled by the control module 53 to slide up and down within the lifting groove 431. The lifting seat 432 further includes a pneumatic cylinder 4321, one end of which is connected to the telescopic arm 42, and the pneumatic cylinder 4321 is electrically connected to the control module 53. The pneumatic cylinder 4321, controlled by the control module 53, extends and retracts the telescopic arm 42. In the control step S02, the first positioning step S03, the second positioning step S04, and the third positioning step S05, the height of the lifting seat 432 and the extension length of the telescopic arm 42 are adjusted to adjust the area and depth of the stamped part 41 corresponding to the hand tool A. In this way, in addition to accommodating hand tools A of various sizes, it can also print on hand tools A at different positions and depths, such as... Figure 1 , 2 As shown in 3, 4, 8A, and 8B.

[0019] Furthermore, the control unit 5 has a screen display 51, which is electrically connected to the control module 53 and the sensing module 61. The screen display 51 shows the speed and position of the slider 22 on the slide rail 21, the rotational speed of the servo motor 31, the lifting position and speed of the lifting member 43, the extension length of the telescopic arm 42, and the position changes of each positioning ball 3212. Through the screen display 51, the operating status of the slider 22, the servo motor 31, the lifting member 43, the telescopic arm 42, and each positioning ball 3212 can be observed, allowing for real-time monitoring of the printing process and effectively ensuring a smooth printing workflow. Figure 1 , 2 As shown in Figures 3 and 8A.

[0020] Furthermore, during control step S02, the control module 53 further includes a built-in setting unit 531. The screen display 51 shows the interface of the setting unit 531 and allows for setting or adjusting the sliding position and speed of the slider 22 on the slide rail 21, the rotational speed of the servo motor 31, the lifting position and speed of the lifting member 43, and the extension length of the telescopic arm 42, such as... Figures 1 to 8B As shown.

[0021] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
