[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the 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 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.

[0024] Refer to Figure 1 、 Figure 4 and Figure 5, An embodiment provided by the present utility model: A lithium battery contact heating and baking device, including a heating plate 1. A plurality of moving rods 2 are slidably connected to the front end of the inner wall of the heating plate 1. A plurality of extrusion blocks 4 are fixedly connected to the rear ends of the moving rods 2. The top end of a fixed block 9 is fixedly connected to a heating box 11. A plug-in board 12 is fixedly connected to the left end of the heating box 11. A plug-in slot 13 is fixedly connected to the right end of the heating box 11. Pressure-receiving grooves 7 are respectively formed in the inner walls of the control rods 6. First springs 5 are fixedly connected to the right ends of the control rods 6. The right ends of the first springs 5 are fixedly connected to the right end of the inner wall of the heating plate 1. A clamping block 8 is fixedly connected to the left end of the control rod 6. A fixing groove 10 is formed in the inner wall of the fixed block 9. The clamping block 8 and the fixing groove 10 are in a matching shape. Pulling springs 3 are fixedly connected to the rear ends of the extrusion blocks 4. The front ends of the pulling springs 3 are fixedly connected to the front end of the inner wall of the heating plate 1. The upper and lower ends of the extrusion blocks 4 are respectively slidably connected to the upper and lower ends of the inner wall of the heating plate 1. The upper and lower ends of the control rods 6 are respectively slidably connected to the upper and lower ends of the inner wall of the heating plate 1.

[0025] Specifically, the pulling springs 3 and the first springs 5 in the device are both made of good heat-resistant materials and can be used for a long time in a high-temperature environment. When the heating plate 1 is started, the heating wire inside the heating plate 1 will convert electrical energy into heat energy. The heat of the heating plate 1 is conducted to the heating box 11 to heat the lithium battery. The heating box 11 is a good heat-conducting material. Later, when a certain heating box 11 is damaged, just press the moving rod 2 on the front side of the heating plate 1 to make the moving rod 2 drive the extrusion block 4 to move backward. The extrusion block 4 enters the pressure-receiving groove 7, which will drive the control rod 6 to move to the right, so that the control rod 6 drives the clamping block 8 to disengage from the fixing groove 10, making the fixed block 9 no longer fixed. At this time, the damaged heating box 11 can be taken out upward, so that the plug-in board 12 and the plug-in slot 13 on the left and right sides of the heating box 11 are respectively disengaged from the adjacent heating box 11. The plug-in board 12 and the plug-in slot 13 can make the heating boxes 11 connected to each other more tightly and can conduct heat to each other. Finally, a new heating box 11 is replaced.

[0026] Refer to Figure 2 and Figure 3 , clamping plates 15 are respectively fixedly connected to the opposite ends of the second spring 14. A plurality of fixing plates 16 are fixedly connected to the opposite ends of the clamping plates 15. Rotating shafts 17 are fixedly connected to the opposite ends of the fixing plates 16. Rollers 18 are rotatably connected to the outer walls of the rotating shafts 17.

[0027] Specifically, the second spring 14 in the device is made of a good heat-resistant material and can be used for a long time in a high-temperature environment. Insert the lithium battery to be baked into the middle of the clamping plate 15, and the rollers 18 will roll on the surface of the lithium battery, thus reducing the direct friction between the lithium battery and the clamping plate 15 when inserted. At the same time, the second springs 14 on both sides can adaptively adjust the clamping plate 15 according to the size of the lithium battery, so that the clamping plate 15 drives the rollers 18 to clamp the lithium battery, realizing the clamping of lithium batteries of different specifications, expanding the scope of use, and avoiding scratching the surface of the lithium battery by the clamping plate 15 when putting in and taking out the lithium battery, protecting the appearance quality of the lithium battery.

[0028] Working principle: When in use, insert the lithium battery to be baked into the middle of the clamping plate 15, and the rollers 18 will roll on the surface of the lithium battery, thus reducing the direct friction between the lithium battery and the clamping plate 15 when inserted. At the same time, the second springs 14 on both sides can adaptively adjust the clamping plate 15 according to the size of the lithium battery, so that the clamping plate 15 drives the rollers 18 to clamp the lithium battery. Then start the heating plate 1, and the heat of the heating plate 1 is conducted to the heating box 11 to heat the lithium battery. In the later stage, when a certain heating box 11 is damaged, just press the moving rod 2 on the front side of the heating plate 1, so that the moving rod 2 drives the extrusion block 4 to move backward. The extrusion block 4 enters the pressure receiving groove 7, which will drive the control rod 6 to move to the right, so that the control rod 6 drives the clamping block 8 to disengage from the fixed groove 10, making the fixed block 9 no longer fixed. At this time, the damaged heating box 11 can be taken out upward, and then a new heating box 11 can be replaced and put on.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
