Description

Technical Field

[0001] This utility model belongs to the field of marking machine technology, specifically relating to a modular handheld laser marking machine. Background Technology

[0002] A handheld laser marking machine is a handheld device that allows you to move the marking module to the target location by hand. The machine then marks the target location using laser technology. Handheld marking machines can quickly adjust or reach the marking position by moving the marking head to the target location, making them more flexible to use than traditional marking machines.

[0003] However, existing marking machines have limited functionality and cannot adapt to marking various character types. To address this, Chinese Patent CN221582364U discloses a multi-purpose marking machine, comprising a handheld laser marking gun body, a protective cover, a base plate, and an encoder body. The bottom end of the handheld laser marking gun body engages with the top end of the protective cover, and the handheld laser marking gun body and the protective cover are fixed together by a first mounting screw. The bottom end of the protective cover connects with the top end of the base plate, and the protective cover and the base plate are fixed together by a second mounting screw. The first mounting screw facilitates the replacement of the protective cover when disassembling the handheld laser marking gun body. Different types of protective covers can be used for multi-purpose marking, such as a long character protective cover for marking long strings, or a regular protective cover for regular marking, thus achieving a multi-purpose marking effect.

[0004] However, in the above solution, the encoder used to realize the function is connected to the laser marking machine body through a connecting cable, which requires additional action during use, resulting in low ease of use. Therefore, a modular handheld laser marking machine that is both easy to use and ensures modular functionality is needed. Utility Model Content

[0025] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0026] Please see Figure 1-6 A modular handheld laser marking machine includes a marking machine body and a conical protective cover 1. The marking machine body includes a handheld module and a main body that are electrically connected to each other. The conical protective cover 1 is detachably connected to the light-emitting part of the handheld module.

[0027] Specifically, the cone-shaped shield 1 is a square pyramid shape. The cone-shaped shield 1 includes a hollow square frustum as the shield body 14. The smaller opening side of the hollow square frustum extends upward to form a hollow square prism. The hollow square prism serves as the shield connecting part 13. At the same time, the light-emitting surface of the handheld module extends outward with a fixing cylinder in conjunction with the shield connecting part 13. The inner shape of the cross-section of the fixing cylinder is consistent with the outer shape of the cross-section of the shield connecting part 13. At this time, the shield connecting part 13 can be inserted into the fixing cylinder to complete the contact with the handheld module.

[0028] Meanwhile, the fixed cylinder and the protective cover connecting part 13 are respectively provided with screw interfaces. After the protective cover connecting part 13 is inserted into the fixed cylinder, screws are screwed into the screw interfaces to complete the connection between the conical protective cover 1 and the handheld module.

[0029] During disassembly, remove the screws and pull the conical cover 1 away from the handheld module to complete the disassembly.

[0030] A functional module 11 is provided on the side of the conical shield 1 away from the handheld module. The control module is electrically connected to the functional module 11. A control module is provided inside the conical shield 1 on the side close to the handheld module. An electrical contact point one is provided on the side of the control module close to the handheld module. An electrical contact point two is provided on the handheld module close to the control module. Electrical contact point one and electrical contact point two are electrically connected to each other when the conical shield 1 is connected to the handheld module. The handheld module controls the functional module 11 through the control module.

[0031] Specifically, regarding the fixing of the functional module 11 and the conical cover 1, the functional module 11 includes a fixing frame 112 and a functional part 111. The fixing frame 112 is located at the opening on the side of the conical cover 1 away from the handheld module, and the functional part 111 is located outside the fixing frame 112.

[0032] Since the conical shield 1 is a square pyramid, and the opening on the side of the conical shield 1 away from the handheld module is also rectangular, in order to ensure that the inner side of the fixing frame 112 fits snugly against the opening on the side of the conical shield 1 away from the handheld module and improve the fixing effect, the fixing frame 112 is designed so that the opening on the side of the conical shield 1 away from the handheld module is rectangular.

[0033] By setting fixed electrical contact point one and electrical contact point two, and making electrical contact point one and electrical contact point two automatically establish an electrical connection when the handheld module is connected to the conical cover 1, the functional module 11 on the conical cover 1 can be directly controlled by the handheld module without additional wiring procedures, reducing the usage procedures and improving the ease of use. At the same time, when it is necessary to replace the conical cover 1 with different functions, the old cover 1 can be directly removed and replaced with the new cover 1, ensuring modular functionality.

[0034] The functional unit 111 is either a two-roller assembly 1111 or two electromagnets 1112. The two-roller assembly 1111 is arranged on both sides of the rectangular fixed frame 112 symmetrically. Each roller assembly 1111 includes at least one roller whose edge away from the handheld module is flush with the lower edge of the functional module 11. The two electromagnets 1112 are arranged on both sides of the fixed frame 112 symmetrically and whose edges away from the handheld module are flush with the lower edge of the functional module 11. In this embodiment, the lower edge of the functional module 11 is the side of the fixed frame 112 away from the handheld module. The two rollers serve as rollers for the handheld module together with the conical protective cover 1. The rollers rotate and drive the handheld module to output start or stop commands to the electromagnets 1112 through the control module, thereby controlling the start and stop of the electromagnets 1112.

[0035] The axis lines of the two rollers 1111 are parallel to each other. When in use, the user commands the rollers 1111 to rotate through the handheld module. The rollers 1111 drive the protective cover 1 and the handheld module to move forward on the marking surface in a direction perpendicular to the axis line, thus completing the movement of the marking point.

[0036] Specifically, the roller assembly 1111 of the functional unit 111 also includes an encoder 1113. The encoder 1113 is electrically connected to the control module. The encoder 1113 is used to convert the rotation speed of the roller assembly into a code and upload it to the control module, and then to the handheld module. The user reads the rotation speed of the roller through the input panel on the handheld module and then determines the moving speed of the handheld module.

[0037] Functional module 11 is connected to the control module via a connecting cable;

[0038] When the two electromagnets 1112 are activated, they attract the handheld module along with the protective cover 1 to the marking surface, reducing the effort required by the operator.

[0039] The handheld module is equipped with an input panel, which is electrically connected to the electrical contact point. The input panel is used to control the function module 11.

[0040] Working principle and usage process of this utility model:

[0041] When the conical cover 1 is installed, the cover connecting part 13 of the conical cover 1 is aligned with the fixing cylinder of the handheld module and inserted, and the cover connecting part 13 is connected to the fixing cylinder to complete the connection between the conical cover 1 and the handheld module. At this time, the interface constituting electrical contact point one is inserted into electrical contact point two of the handheld module, and the electrical connection of the functional module 11 on the conical cover 1 is completed simultaneously. At this time, the handheld module, the control module and the functional module 11 are connected in series, so that the handheld module can control the functional module 11.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
