[0030] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figures 1 - 10 As shown, the lighter baking jig of the present utility model includes a baking tray 1 and a first positioning seat 2 that are inserted into each other. A first negative pressure pipeline 3 is provided on the baking tray 1, and a second negative pressure pipeline 4 is provided on the first positioning seat 2. The first negative pressure pipeline 3 is inserted into the second negative pressure pipeline 4. One end of the second negative pressure pipeline 4 is communicated with the first negative pressure pipeline 3, and the other end of the second negative pressure pipeline 4 is connected with a suction cup 5 for adsorbing and positioning the lighter.

[0032] The lighter baking fixture of the present application includes a baking tray 1 and a first positioning seat 2. The baking tray 1 is used to position and support the first positioning seat 2 and connect to the negative pressure pipeline on the first positioning seat 2. The first positioning seat 2 is used to position and support the lighter and perform the adsorption and positioning operation on the lighter through the negative pressure pipeline. Specifically, a first negative pressure pipeline 3 is provided on the baking tray 1, and a second negative pressure pipeline 4 is provided on the first positioning seat 2. When negative pressure is generated in the first negative pressure pipeline 3, since the first negative pressure pipeline 3 is inserted into the second negative pressure pipeline 4, the first negative pressure pipeline 3 is connected to the second negative pressure pipeline 4, thereby establishing negative pressure in the second negative pressure pipeline 4. Further, a suction cup 5 is provided on the first positioning seat 2, and the suction cup 5 is connected to the second negative pressure pipeline 4. Therefore, the suction cup 5 generates an adsorption force under the action of negative pressure, and the lighter is adsorbed on the first positioning seat 2 through this adsorption force, without tying the lighter to the first positioning seat 2 with tape, improving the baking operation efficiency. Among them, the surface of the lighter needs to be baked, so no positioning structure that affects the baking effect can be provided on the surface of the lighter. Therefore, in the prior art, the lighter is tied to the first positioning seat 2 with tape. In response to this problem, the present application adsorbs the lighter on the first positioning seat 2 through the adsorption force generated by the cooperation of negative pressure and the suction cup 5, and there is no positioning structure on the surface of the lighter to block, effectively improving the baking effect and baking efficiency. Among them, the first positioning seat 2 is inserted into the baking tray 1. When the adsorption operation needs to be performed on the lighter, the staff inserts the first positioning seat 2 into the corresponding position on the baking tray 1, and at the same time, the first negative pressure pipeline 3 is inserted into the second negative pressure pipeline 4. With the adsorption force of the second negative pressure pipeline 4, the staff can directly place the lighter on the first positioning seat 2 to achieve the adsorption and clamping operation of the lighter.

[0033] In one embodiment, a negative pressure interface 6 is provided on the baking tray 1, and a negative pressure device 7 is connected to the negative pressure interface 6. One end of the first negative pressure pipeline 3 far from the second negative pressure pipeline 4 is connected to the negative pressure interface 6.

[0034] A first negative pressure pipeline 3 is provided on the baking tray 1, and the first negative pressure pipeline 3 is connected to the second negative pressure pipeline 4. To establish negative pressure in the second negative pressure pipeline 4 through the first negative pressure pipeline 3, corresponding equipment is required to establish negative pressure in the first negative pressure pipeline 3. Specifically, as Figure 1 shown, a negative pressure interface 6 is provided on the baking tray 1, and a negative pressure device 7 is connected to the negative pressure interface 6. Negative pressure is established through this negative pressure device 7, and the vacuum degree can be adjusted through this negative pressure device 7 to adjust the negative pressure magnitude. Among them, the negative pressure interface 6 can be provided at the bottom or side of the baking tray 1. Figure 1As shown, it is arranged at the bottom, and the position of the negative pressure interface 6 is designed according to actual requirements. Further, the negative pressure interface 6 is connected to one end of the first negative pressure pipeline 3 away from the second negative pressure pipeline 4. When the negative pressure device 7 establishes negative pressure, negative pressure in the first negative pressure pipeline 3 is established through the negative pressure interface 6, and then negative pressure in the second negative pressure pipeline 4 is established through the first negative pressure pipeline 3, so as to realize the adsorption and clamping effect on the lighter through the suction cup 5.

[0035] In one embodiment, a sealing ring 8 is arranged on the outer wall of the first negative pressure pipeline 3. The inner ring of the sealing ring 8 is hermetically arranged with the outer wall of the first negative pressure pipeline 3, and the outer ring of the sealing ring 8 is hermetically arranged with the inner wall of the second negative pressure pipeline 4.

[0036] When the first positioning seat 2 is inserted into the baking tray 1, the first negative pressure pipeline 3 is inserted into the second negative pressure pipeline 4. To establish effective negative pressure, the connection between the first negative pressure pipeline 3 and the second negative pressure pipeline 4 needs to be hermetically connected. Specifically, as Figure 4 and Figure 7 shown, a sealing ring 8 is arranged on the outer wall of the first negative pressure pipeline 3, so that the inner ring of the sealing ring 8 is hermetically connected to the outer wall of the first negative pressure pipeline 3; when the first negative pressure pipeline 3 is inserted into the second negative pressure pipeline 4, the outer ring of the sealing ring 8 is hermetically connected to the inner wall of the second negative pressure pipeline 4, thereby realizing the effective sealing between the first negative pressure pipeline 3 and the second negative pressure pipeline 4 to establish effective negative pressure and improve the negative pressure effect.

[0037] In one embodiment, a plurality of the first negative pressure pipelines 3, the second negative pressure pipelines 4 and the suction cups 5 are provided. The first negative pressure pipelines 3 communicate with the second negative pressure pipelines 4 in one-to-one correspondence, and the second negative pressure pipelines 4 communicate with the suction cups 5 in one-to-one correspondence.

[0038] A plurality of the first negative pressure pipelines 3, the second negative pressure pipelines 4 and the suction cups 5 are provided. As Figure 1 shown, one first negative pressure pipeline 3 corresponds to one second negative pressure pipeline 4. Therefore, any one of the first negative pressure pipelines 3 is inserted into the corresponding second negative pressure pipeline 4, so that the first negative pressure pipeline 3 communicates with the corresponding second negative pressure pipeline 4; one second negative pressure pipeline 4 corresponds to one suction cup 5, and any one of the second negative pressure pipelines 4 communicates with the corresponding suction cup 5.

Therefore, when the first negative pressure pipeline 3 establishes negative pressure, the connecting pipeline 11 and the connecting cavity 10 establish negative pressure, wherein the adsorption pipeline 9 is a pipeline connected to the suction cup 5, and the adsorption pipeline 9 and the suction cup 5 are provided in multiple numbers, and the suction cups 5 are connected to the corresponding adsorption pipelines 9 one by one, and all the connecting pipelines 11 are connected to the connecting cavity 10, and negative pressure can be established for all the adsorption pipelines 9 through one connecting cavity 10.

Figure 2 As shown, a plurality of first positioning bosses 12 are provided on the first positioning seat 2, and a mounting groove 13 is provided on each first positioning boss 12, through which the suction cup 5 is installed. Furthermore, a first positioning surface 14 is provided on each first positioning boss 12, and all the first positioning surfaces 14 are located in the same plane, and preferably, all the first positioning surfaces 14 are located in the same horizontal plane. When the lighter is adsorbed by the suction cup 5, the adsorption surface on the lighter abuts against the first positioning surface 14, and the lighter is adsorbed and positioned on the first positioning seat 2 by the adsorption force of the suction cup 5 and the cooperation between the first positioning surface 14 and the adsorption surface on the lighter.

[0043] In one embodiment, a second positioning seat 15 is further included.

The first positioning surface 14 and the second positioning surface 19 are located in the same plane.

[0044] The lighter baking jig of the present application further includes a second positioning seat 15. The second positioning seat 15 is slidably arranged on the first positioning seat 2 to adsorb and position a lighter with a larger size through the first positioning seat 2 and the second positioning seat 15, thereby improving versatility. Specifically, as Figure 5 、 Figure 8 and Figure 9 shown, a sliding rod 17 is provided on the second positioning seat 15, and a sliding groove 16 is provided on the first positioning seat 2. The sliding rod 17 is slidably connected in the sliding groove 16, so as to realize the adjustment of the distance between the second positioning seat 15 and the first positioning seat 2. Further, a second positioning boss 18 is provided on the second positioning seat 15, and a second positioning surface 19 is provided on the second positioning boss 18. The first positioning surface 14 and the second positioning surface 19 are located in the same plane. Preferably, the first positioning surface 14 and the second positioning surface 19 are located in the same horizontal plane. When the lighter is adsorbed by the suction cup 5, the adsorption surface on the lighter abuts against the first positioning surface 14 and the second positioning surface 19. The lighter is adsorbed and positioned on the first positioning seat 2 and the second positioning seat 15 through the adsorption force of the suction cup 5 and the cooperation between the first positioning surface 14, the second positioning surface 19 and the adsorption surface on the lighter. By adjusting the distance between the second positioning seat 15 and the first positioning seat 2, the distance between the first positioning surface 14 and the second positioning surface 19 is adjusted. When the distance between the first positioning surface 14 and the second positioning surface 19 is adjusted to be larger, a lighter with a larger size can be supported and positioned by the first positioning surface 14 and the second positioning surface 19. When the distance between the first positioning surface 14 and the second positioning surface 19 is adjusted to be smaller, a lighter with a smaller size can be supported and positioned by the first positioning surface 14 and the second positioning surface 19.

[0045] In one embodiment, a positioning groove 20 is provided on the sliding rod 17, and a positioning ball 21 is slidably arranged in the positioning groove 20. A compression spring 22 is provided between the positioning groove 20 and the positioning ball 21. A plurality of limiting surfaces are arranged on the sliding groove 16 along the sliding direction. The positioning ball 21 abuts against or separates from the limiting surfaces, so that the sliding rod 17 is in a locked state or an unlocked state relative to the sliding groove 16.

[0046] The sliding rod 17 is slidably arranged in the sliding groove 16, and the sliding rod 17 can be in a locked state at different positions relative to the sliding groove 16. Specifically, as Figure 9 shown, a positioning groove 20 is arranged on the sliding rod 17. Preferably, the axis of the positioning groove 20 is perpendicular to the axis of the sliding rod 17, and a positioning ball 21 is slidably arranged in the positioning groove 20 along its axis direction.

The positioning ball 21 on the sliding rod 17 can cooperate with any one of the limiting grooves 23 to lock the sliding rod 17 relative to the sliding groove 16 at any position. When the staff needs to increase the distance between the second positioning seat 15 and the first positioning seat 2, the staff applies a certain pulling force to the sliding rod 17 on the second positioning seat 15, so that the groove wall of the sliding groove 16 presses the positioning ball 21, and the positioning ball 21 moves towards the bottom of the positioning groove 20 in the positioning groove 20. At the same time, the compression spring 22 is further compressed.
