In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0045] See also Figure 1 and Figure 2The positioning tool provided in the embodiment of the present application is now described. The positioning tool provided in the embodiment of the present application is used for positioning the product 40.

[0046] Reference Figure 1 The product 40 at least includes a mounting portion 41, and the mounting portion 41 has a first magnetic component (not shown in the figure). The product 40 can be connected to other devices through the first magnetic component, and the long strip structure can ensure a more stable connection. In some embodiments, the product 40 is a magnetic keyboard, and the mounting portion 41 is the magnetic edge that connects the magnetic keyboard to an electronic device (such as a tablet or a smart phone).

[0047] Reference Figure 2 and Figure 3 The positioning tool includes a base plate 10, a positioning component 20 and a second magnetic attraction component 30.

[0048] The bottom plate 10 is used to support the product 40. When positioning the product 40, the product 40 can be placed on the bottom plate 10 to stably support the product 40, and then the product 40 can be positioned on the bottom plate 10 by relying on the positioning assembly 20. It should be noted that the bottom plate 10 is not a complete plane, and corresponding grooves and protrusions can be set according to the specific shape of the bottom of the product 40 to better adapt to and support the product 40.

[0049] Reference Figure 2 The positioning component 20 is protruded from the bottom plate 10 and forms a positioning groove 21 on the bottom plate 10 that matches the shape of the mounting portion 41. The positioning component 20 protrudes from the bottom plate 10, thereby forming a positioning groove 21 on the bottom plate 10. The shape of the positioning groove 21 matches the mounting portion 41 of the product 40, so that the mounting portion 41 can be placed in the positioning groove 21. After the mounting portion 41 is positioned, the position of the product 40 is also determined. It should be noted that the groove wall of the positioning groove 21 can be continuous or intermittent, that is, an opening 2512 can be set on the groove wall, as long as the mounting portion 41 can be positioned.

[0050] Reference Figure 3 , the second magnetic member 30 is located in the positioning groove 21 and is provided on the bottom plate 10, and the second magnetic member 30 can be magnetically adsorbed with the first magnetic member to fix the mounting portion 41. The second magnetic member 30 is fixed on the bottom plate 10 and in the positioning groove 21. When the mounting portion 41 is placed in the positioning groove 21, the first magnetic member inside the mounting portion 41 can be adsorbed with the second magnetic member 30, thereby fixing the mounting portion 41 in the positioning groove 21 to prevent the product 40 from tilting and affecting the marking effect. Fixing the mounting portion 41 by adsorption with the first magnetic member also makes it convenient to unload the material after marking.

[0051] It is understandable that the base plate 10 and the positioning assembly 20 are not attracted to the first magnetic member, and only the second magnetic member 30 is attracted to the first magnetic member. It should be noted that the first magnetic member and the second magnetic member are attracted to each other, and at least one of them is a magnet (such as a magnet), and the other can be a magnet or a magnetic member attracted by a magnet, such as an iron bar. In some embodiments, the first magnetic member is a magnet, and the second magnetic member is an iron bar.

[0052] Reference Figure 3 The mounting portion 41 is in the shape of a long strip, and the second magnetic member 30 includes a main body 31 extending along the length direction X of the positioning groove 21 and a fixing portion 32 provided at both ends of the main body 31, and the fixing portion 32 is fixedly connected to the bottom plate 10. By extending the main body 31 along the length direction X, more parts that can be adsorbed by the first magnetic member in the mounting portion 41 are formed, so as to better adsorb with the magnetism. Even if the first magnetic member in the mounting portion 41 is installed with an offset position, the adsorption effect is not affected, and it is ensured that the product 40 will not be lifted up when positioned. The fixing portion 32 is connected to the bottom plate 10 and can be fixed by screws, bolts or adhesives.

[0053] Reference Figure 2 and Figure 3 The positioning assembly 20 includes a fixed rib 22 and an adjusting block 23. The fixed rib 22 is protruding from the bottom plate 10 and extending along the length direction X. The adjusting block 23 is parallel to the fixed rib 22. The positioning groove 21 is between the adjusting block 23 and the fixed rib 22. The adjusting block 23 can be close to or away from the fixed rib 22 on the bottom plate 10 to adjust the width of the positioning groove 21. The fixed rib 22 and the adjusting block 23 are arranged opposite to each other, and there is a spacing between them. The spacing is the positioning groove 21, that is, the fixed rib 22 and the adjusting block 23 are two opposite side walls of the positioning groove 21, and both are two side walls along the length direction X. In the embodiment of the present application, the position of the adjustment block 23 on the base plate 10 is adjustable. By adjusting its position, the distance between the adjustment block 23 and the fixed retaining edge 22 can be changed, thereby adjusting the width of the positioning groove 21. In this way, different models of products 40 (different models of products 40 have different widths of the mounting portion 41).

[0054] The width of the main body 31 is smaller than the minimum width of the positioning groove 21, and one side of the main body 31 is close to the fixed rib 22. That is, the main body 31 of the second magnetic member 30 is on the side close to the fixed rib 22, and because the width is smaller than the minimum width of the positioning groove 21, during the process of adjusting the width of the adjusting block 23, the main body 31 will not interfere with the adjusting block 23, and will not affect the normal adjustment.

[0055] Reference Figure 3 and Figure 6 The bottom plate 10 is provided with a first slide groove 11 arranged along the width direction Y of the positioning groove 21, and the first slide groove 11 is provided with a fixing hole 12. The adjusting block 23 includes a sliding portion 231 and a blocking portion 232 connected to one end of the sliding portion 231, the sliding portion 231 is located in the first slide groove 11 and can slide along the first slide groove 11, the sliding portion 231 is provided with a waist-shaped hole 233 corresponding to the fixing hole 12, and a fixing member is passed through the waist-shaped hole 233 and the fixing hole 12. The first slide groove 11 is rectangular, and correspondingly, the sliding portion 231 is also rectangular, and the size of the sliding portion 231 along the width direction Y of the positioning groove 21 is smaller than the size of the first slide groove 11 along the width direction Y of the positioning groove 21, so that the sliding portion 231 can slide in the first slide groove 11. The blocking portion 232 is connected to the sliding portion 231 in a turning manner, so that the adjustment block 23 is L-shaped. The blocking portion 232 and the fixed rib 22 respectively form two side walls of the positioning groove 21. When the sliding portion 231 slides in the first sliding groove 11, the distance between the blocking portion 232 and the fixed rib 22 changes accordingly.

[0056] The waist-shaped hole 233 and the fixing hole 12 are arranged so that the sliding part 231 can be fixed on the bottom plate 10 by passing the fixing member through the waist-shaped hole 233. The waist-shaped hole 233 can adapt to the sliding of the sliding part in the first slide groove 11, ensuring that it can still be fixed after sliding. Specifically, the fixing hole 12 can be a screw hole, and the fixing member can be a screw.

[0057] Reference Figure 2 and Figure 3 The positioning assembly 20 further includes a fixed stopper 24 and an elastic stopper 25. The fixed stopper 24 is provided on the bottom plate 10 and is located at one end of the fixed rib 22. The elastic stopper 25 is provided on the bottom plate 10 and is located at the other end of the fixed rib 22. The elastic stopper 25 can be elastically extended toward one end of the fixed stopper 24. The minimum distance between the elastic stopper 25 and the fixed stopper 24 is less than the minimum length of the mounting portion 41. The fixed stopper 24 and the elastic stopper 25 are respectively located at the two ends of the positioning groove 21 along the length direction X to form the other two side walls of the positioning groove 21.

[0058] The mounting portion 41 has size differences due to production tolerances. If the length of the positioning groove 21 is fixed, when the length is too large, the positioning groove 21 cannot be inserted. When the length is too small, there is a gap in the positioning groove 21 along the length direction X, and the position of the product 40 may be offset. This will affect the marking accuracy and fail to meet customer needs. Therefore, in the embodiment of the present application, the end of the elastic stopper 25 facing the fixed stopper 24 is set to be elastically retractable, which can adapt to mounting portions 41 of different lengths. Since the minimum distance between the elastic stopper 25 and the fixed stopper 24 is less than the minimum length of the mounting portion 41, even the mounting portion 41 of the minimum length can be clamped to avoid product 40 offset and ensure marking accuracy.

[0059] Reference Figure 3 , Figure 7 and Figure 8 The elastic stopper 25 includes a shell 251 , a butt joint 252 , an elastic member 253 and a cover plate 254 .

[0060] The housing 251 is disposed on the bottom plate 10, and the housing 251 is provided with a second slide groove 2511 extending along the length direction X, and an end of the housing 251 close to the fixed stopper 24 is provided with an opening 2512 connected to the second slide groove 2511. The housing 251 is fixed to the bottom plate 10, and can be fixed by screws, bolts or adhesive. The housing 251 is provided with a second slide groove 2511 for the abutment 252 to slide along the length direction X, so as to adjust the length of the positioning groove 21 along the length direction X to adapt to the mounting parts 41 with different length differences. It can be understood that the width of the opening 2512 is smaller than the width of the second slide groove 2511 to prevent the abutment 252 from escaping from the slide groove at the opening 2512. The shell 251 can also be provided with a waist-shaped hole 233, which is connected to the base plate 10 through the waist-shaped hole 233, so as to adjust the position of the elastic stop block 25 in the length direction X of the positioning groove 21 and change the overall length of the positioning groove 21 to accommodate more types of products 40 (the width of the mounting portion 41 of different models of products 40 is different).

[0061] Reference Figure 8 , one end of the abutment joint 252 is located in the second slide groove 2511 and can slide along the second slide groove 2511, and the other end extends out of the opening 2512. The abutment joint 252 can be T-shaped, with one horizontal end located in the second slide groove 2511 and one vertical end extending out of the opening 2512. When the abutment joint 252 slides in the second slide groove 2511, the length of the end of the abutment joint 252 extending out of the opening 2512 also changes accordingly, thereby changing the length of the positioning groove 21. That is, if the abutment joint 252 slides in the direction where the fixed stopper 24 is located, the length of the positioning groove 21 decreases; if the abutment joint 252 slides in the direction away from the fixed stopper 24, the length of the positioning groove 21 decreases and increases.

[0062] Reference Figure 8 The elastic member 253 is disposed in the second slide groove 2511 and pushes the abutting head 252 toward the fixed stopper 24. After the mounting portion 41 is placed in the positioning groove 21, the elastic force of the elastic member 253 pushes the abutting head 252 to abut against the mounting portion 41, ensuring that there is no gap between the mounting portion 41 and the positioning groove 21 in the length direction X, thereby ensuring that the product 40 is accurately positioned. Specifically, the elastic member 253 is a compression spring.

[0063] The cover plate 254 is disposed on the housing 251 and closes the notch of the second slide groove 2511 to prevent the elastic member 253 and the abutting head 252 from being separated from the second slide groove 2511 .

[0064] Reference Fig. 9 The elastic stopper 25 further includes a plug 27. A through hole 2513 is provided on the side wall of the second slide groove 2511 opposite to the opening 2512. The plug 27 is located in the through hole 2513 and its position in the through hole 2513 can be adjusted. One end of the elastic member 253 is inserted into the through hole 2513 and abuts against the plug 27. One end of the elastic member 253 is inserted into the through hole 2513 and abuts against the plug 27. By changing the position of the plug 27 in the through hole 2513, the compression degree of the elastic member 253 can be changed, so that the abutment elastic force of the abutting head 252 on the mounting portion 41 can be adjusted to control the adaptive force. Specifically, the through hole 2513 can be a screw hole, and the plug 27 can be a top screw or a screw.

[0065] Furthermore, an inclined guide surface 26 is provided on the upper edge of the positioning groove 21 , which can facilitate guiding the mounting portion 41 into the positioning groove 21 .

[0066] In some embodiments, the fixed rib 22 and the fixed stopper 24 are integrally connected to the bottom plate 10. The fixed rib 22 and the fixed stopper 24 can also be connected together to form an L shape.

[0067] In some embodiments, the product 40 further includes a product body portion 42 connected to the mounting portion 41 , and a receiving groove 13 for the product body portion 42 to be embedded is formed on the base plate 10 to better position and support the product and improve the marking effect.

[0068] An embodiment of the present application also provides a marking device, including the positioning tool in any of the above embodiments.

[0069] The marking device of the embodiment of the present application includes the positioning tool in any of the above embodiments, and thus has the beneficial effects brought by the positioning tool in any of the above embodiments, which will not be described in detail here.
