[0025] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein.

The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0027] When used herein, the singular forms "a", "an", and "said / the" may also include plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" etc. specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0028] A laser engraving fool-proof structure comprises a matching substrate 1 and a fixture body 2.

[0029] The substrate 1 is square and has two opposite long sides 14, two opposite short sides 15 and four end corners 16. Two positioning holes 12 and one fool-proof hole 13 are provided on the substrate 1. The two positioning holes 12 are respectively provided at two end corners 16 close to the same long side 14, and the fool-proof hole 13 is provided on one side close to the other opposite long side 14.

[0030] In addition, the distances between the center of the fool-proof hole 13 and the short sides 15 on both sides are not equal, and the distances between the center of the fool-proof hole 13 and the short sides 15 on either side are not equal to the distances between the center of the positioning hole 12 and the short sides 15 on the adjacent side.

[0031] Two positioning pins 22 and one fool-proofing pin 23 are provided on the top of the fixture body 2 . The two positioning pins 22 correspond to the two positioning holes 12 respectively, and the fool-proofing pin 23 corresponds to the fool-proofing hole 13 .

[0032] In the process of installing the substrate 1 on the fixture body 2, if the up-down or front-back installation is wrong, the anti-fool hole 13 cannot cooperate with the anti-fool pin 23, that is, the substrate 1 cannot be fixed. Only when it is installed correctly can the substrate 1 be fixed, thereby ensuring that the substrate 1 is laser engraved at the correct position to avoid the scrapping of the substrate 1.

[0033] In this embodiment, a plurality of single boards 11 are arranged on the substrate 1, and multiple single boards 11 can be engraved at the same time by means of a plate-making method. The top of the jig body 2 is provided with a component slot 21 corresponding to the single board 11 one by one, and the shape of the component slot 21 is adapted to the shape of the single board 11. If various electrical components are pre-installed at the bottom of the single board 11, the component slot 21 can provide storage space for the electrical components to avoid pressing the electrical components.

[0034] In addition, the fixture body 2 is provided with at least two mounting grooves 24, each mounting groove 24 is provided with a touch switch 25, the top of the touch switch 25 is flush with the top of the fixture body 2, and the buttons of the touch switch 25 extend from the top of the fixture body 2.

[0035] A reset switch 3 is also provided on one side of the fixture body 2. The reset switch 3 is used to control the start of the laser engraving device. The reset switch 3 and all the touch switches 25 are connected in series to the laser engraving device, so that the laser engraving device is turned on only when the reset switch 3 and all the touch switches 25 are pressed at the same time.

[0036] Therefore, if the substrate 1 is not installed in place, so that any of the touch switches 25 are not pressed, the laser engraving device cannot be turned on, thereby further ensuring the correct laser engraving and avoiding the scrapping of the substrate 1. Only when the substrate 1 is installed in place, the bottom of the substrate 1 is tightly attached to the top of the fixture, and all the touch switches 25 are pressed, can the laser engraving device be turned on by pressing the reset switch 3 to perform engraving.

[0037] This embodiment can avoid upside-down or front-side-down installation errors of the substrate 1 through the cooperation of the mechanical fool-proofing structure and the circuit fool-proofing structure, and can ensure that the substrate 1 is installed in place, ensure that laser engraving is performed at the correct position of the substrate 1, and improve the success rate of laser engraving.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
