[0031] See also Figure 1 , the key core positioning jig provided in the embodiment of the present application is now described. The key core positioning jig provided in the embodiment of the present application includes:

[0032] Bottom plate 1, used for supporting the key core;

[0033] The cover plate 2 comprises an outer frame component 21 and a fixing component 22 for abutting against the key core, wherein the fixing component 22 is installed on the side wall of the outer frame component 21, and the outer frame component 21 is hinged to the bottom plate 1;

[0034] The key core is placed on the bottom plate 1 , and is covered on the bottom plate 1 through the outer frame component 21 of the cover plate 2 , so that the fixing component 22 on the cover plate 2 abuts against the key core to keep the key core flat.

[0035] Before positioning the key core, the embodiment of the present application rotates the cover plate 2 away from the base plate 1 to unfold the jig to facilitate the placement of the key core, and then places the key core on the base plate 1. The cover plate 2 is then rotated toward the base plate 1, and the outer frame component 21 of the cover plate 2 is covered on the base plate 1, so that the fixing component 22 on the cover plate 2 abuts against the key core to prevent the edge of the key core from warping up, thereby keeping the key core flat, improving the laser engraving effect, and improving the yield rate of the product.

[0036] The fixing assembly 22 in the embodiment of the present application is generally in contact with the gap between the keycaps on the key core or the edge of the key core to avoid laser processing. Preferably, the fixing assembly 22 is generally in contact with the gap between the keycaps on the key core.

[0037] The outer frame assembly 21 in the embodiment of the present application includes a connecting frame, a left frame and a right frame, the left frame and the right frame are respectively connected to the two ends of the connecting frame, the left frame and the right frame are arranged opposite to each other, and the length direction of the left frame and the right frame is perpendicular to the length direction of the connecting frame, and the connecting frame is hinged to the bottom plate 1. A plurality of fixing components 22 are respectively arranged on the left frame and the right frame.

[0038] The fixing component 22 includes a connecting member 221 and a contact member 222, wherein the contact member 222 is connected to the connecting member 221, and a position adjustment hole 211 is provided on the side wall of the outer frame component 21, wherein the connecting member 221 is inserted into the position adjustment hole 211 of the outer frame component 21 to adjust the position of the connecting member 221, and the contact member 222 is used to contact the gap between the key caps of the key core.

[0039] The abutment member 222 in the embodiment of the present application is a pressure strip whose width matches the gap width between the keycaps on the key core, the connection member 221 is a connection column with external threads on the surface, the position adjustment hole 211 is a waist-shaped hole, and the abutment member 222 is inserted on the connection member 221. The connection member 221 is inserted in the position adjustment hole 211, and the connection member 221 can be adjusted along the length direction of the position adjustment hole 211 to adjust the position of the connection member 221, thereby adjusting the position of the abutment member 222. The connection member 221 is threadedly connected with two nuts, and the two nuts are relatively abutted against the two side edges of the position adjustment hole 211 to fix the position of the connection member 221 on the position adjustment hole 211.

[0040] In addition, a plurality of position adjustment holes 211 may be provided on the side wall of the outer frame assembly 21 . The position adjustment holes 211 are threaded holes. The connector 221 is a threaded rod with external threads on the surface. The position of the connector 221 may be adjusted by replacing the position adjustment holes 211 .

[0041] Since the sizes and arrangements of the keycaps on different key cores are not exactly the same, if the position of the connecting member 221 is fixedly installed on the outer frame assembly 21, it is possible that the abutting member 222 abuts against the keycap of the key core, hindering the laser engraving work. However, by adjusting the position of the connecting member 221 in the position adjustment hole 211, the abutting member 222 can be accurately abutted against the gap between the keycaps on the key core, so that the laser engraving work can be facilitated, and the key core positioning fixture can be applied to a variety of key cores, thereby improving the compatibility of the key core positioning fixture.

[0042] The fixing assembly 22 also includes a fixing piece 223. The connecting piece 221 is provided with a socket for inserting the abutment piece 222 and a fixing hole for inserting the fixing piece 223. The socket is connected to the fixing hole. The length direction of the socket is perpendicular to the length direction of the fixing hole. The abutment piece 222 is inserted into the socket. The fixing piece 223 is inserted into the fixing hole and abuts against the side wall of the abutment piece 222 to fix the abutment piece 222.

[0043] The fixing member 223 in the embodiment of the present application is a screw rod or a bolt, and the fixing hole on the connecting member 221 is a threaded hole. The fixing member 223 is threadedly connected to the fixing hole and abuts against the side wall of the abutting member 222, so that the abutting member 222 can be fixed in the socket of the connecting member 221.

[0044] Since the sizes and arrangements of the keycaps on different key cores are not exactly the same, and the abutment 222 is a bead whose width matches the width of the gap between the keycaps on the key core, if the bead is too long, it may abut against the keycap of the key core, hindering the laser engraving work. The abutment 222 is inserted into the socket, and the position of the abutment 222 in the socket can be adjusted to adjust the length of the abutment 222 extending out of the socket, thereby preventing the abutment 222 from abutting against the keycap on the key core. In this way, the laser engraving work can be facilitated, and the key core positioning jig can be applied to a variety of key cores, thereby improving the compatibility of the key core positioning jig.

[0045] The length direction of the connecting member 221 is perpendicular to the length direction of the abutting member 222. The length direction of the connecting member 221 can also be parallel to the length direction of the abutting member 222.

[0046] There are two types of fixing components 22 in the embodiment of the present application, one is that the length direction of the connecting member 221 is perpendicular to the length direction of the abutting member 222, and is used to fix the two sides of the length direction of the key core parallel to the length direction of the connecting frame of the outer frame component 21, and the other is that the length direction of the connecting member 221 is parallel to the length direction of the abutting member 222, and is used to fix the two sides of the length direction of the key core perpendicular to the length direction of the connecting frame of the outer frame component 21. The left frame and the right frame of the outer frame component 21 are both provided with two types of fixing components 22, and the two types of fixing components 22 cooperate with each other to prevent the edge of the key core from warping up, so as to keep the surface of the key core flat.

[0047] The outer frame assembly 21 is provided with a protrusion 212 protruding toward the bottom plate 1, the position adjustment hole 211 is provided at the protrusion 212, the bottom plate 1 is provided with a notch 11 matching with the protrusion 212, the protrusion 212 is embedded in the notch 11 so that the abutment 222 abuts against the gap between the key caps of the key core.

[0048] When the protrusion 212 in the embodiment of the present application is embedded in the notch 11 , the pressure exerted by the abutment member 222 on the key core can be increased to press down the raised portion of the key core, thereby keeping the processed surface of the key core flat.

[0049] The bottom plate 1 is also provided with a limiting groove 12 for cooperating with the outer frame assembly 21 . When the outer frame assembly 21 is covered on the bottom plate 1 , the outer frame assembly 21 is clamped in the limiting groove 12 .

[0050] The limiting groove 12 in the embodiment of the present application is set at the edge of the bottom plate 1. When the outer frame assembly 21 is covered on the bottom plate 1, the outer frame assembly 21 is clamped in the limiting groove 12, which can prevent the outer frame assembly 21 from shifting after rotation, resulting in the originally adjusted fixing assembly 22 not abutting against the gap between the keycaps on the key core, increasing the number of adjustments of the fixing assembly 22. The limiting groove 12 can make the fixing assembly 22 abut against the gap between the keycaps on the key core, reducing the number of adjustments of the fixing assembly 22 and improving work efficiency.

[0051] The bottom plate 1 is provided with a plurality of ribs 13, which are used to abut against the side wall of the key core, and the plurality of ribs 13 are arranged to form a limit seat for accommodating the key core. The limit seat can prevent the key core from shifting during the laser engraving process, thereby improving the yield rate of the laser engraving process.

[0052] The outer frame assembly 21 is hinged to the bottom plate 1 via a hinge assembly 3 .
