The skilled in the art can reasonably determine the specific meaning of the above words in the present application in combination with the specific content of the technical solution.

[0031] In the field of infrared plate heating, infrared heating technology is to irradiate infrared rays emitted by an infrared radiator to a heated object. Except for reflection and transmission, the rest is absorbed by the object and converted into heat motion of the molecules of the object, thereby heating the object. Infrared heating can only heat specific areas, has the optimal wavelength for the heating object, and can be combined with the production process. Infrared rays are directly absorbed by the heated object without the need for intermediate heat transfer medium, and the heat transfer efficiency is relatively high. Using infrared heating in a coating oven can heat the pole piece. During the use of the infrared heating coating oven, the distance between the infrared plate module and the pole piece needs to be adjusted according to the heating process requirements and the maintenance of the infrared plate. On the market, the distance between the infrared plate module and the pole piece needs to be adjusted by disassembling the entire module to adjust the height of the infrared plate, and the distance between the pole piece and the infrared plate cannot be directly measured. The operation is complicated and repetitive, and the work efficiency is low. The infrared heating device 10 provided in the present application can conveniently and quickly adjust the distance between the infrared heating assembly and the pole piece, and improve the work efficiency of infrared heating.

[0032] Referring to Figure 1 , the infrared heating device 10 includes a base 20, a lifting assembly 30, and an infrared heating assembly 40. The lifting assembly 30 is connected to the base 20 and can be used to adjust the height. The infrared heating assembly 40 is connected to the base 20 through the lifting assembly 30. When the lifting assembly 30 moves up and down, it can drive the infrared heating assembly 40 to move up and down. The infrared heating assembly 40 is used to emit infrared light to heat the pole piece. The lifting assembly 30 adjusts the distance between the infrared heating assembly 40 and the base 20 to adjust the distance between the infrared heating assembly 40 and the pole piece. The lifting assembly 30 includes a rod, a transmission mechanism 32, and a first planar linkage mechanism 34. The rod is provided in the base 20. The transmission mechanism 32 connects the rod and the first planar linkage mechanism 34. The first planar linkage mechanism 34 is connected to the base 20 and the infrared heating assembly 40, respectively. The rod can drive the transmission mechanism 32 to move closer to or away from the base 20, thereby changing the shape of the first planar linkage mechanism 34 to drive the infrared heating assembly 40 to move closer to or away from the base 20. When the infrared heating assembly 40 is close to the pole piece, the heating degree of the pole piece is relatively high. Conversely, when the infrared heating assembly 40 is away from the pole piece, the heating degree of the pole piece is relatively low. By adjusting the distance between the infrared heating assembly 40 and the pole piece, the heating degree of the pole piece by the infrared heating device 10 can be conveniently and quickly controlled. In some embodiments, the base 20 can be provided with a buckle 21. The buckle 21 can fix the base 20 to other components, such as a hull 52.

[0033] Referring to Figure 1 and Figure 2In some embodiments, the lifting assembly 30 comprises a rotating rod 31, a transmission mechanism 32 and a first planar linkage 34, the rotating rod 31 is arranged in the base 20, and the transmission mechanism 32 and the first planar linkage 34 are adjusted by adjusting the rotating rod 31. In some embodiments, a bearing assembly can be sleeved on the rotating rod 31 to make the direction of the rotating rod 31 a preset direction. In some embodiments, one or more rotating rod 31 structures can be arranged on both sides of the base 20. The transmission mechanism 32 connects the rotating rod 31 and the first planar linkage 34, and the first planar linkage 34 connects the base 20 and the infrared heating assembly 40 respectively. When the rotating rod 31 is adjusted, the rotating rod 31 can move the transmission mechanism 32 relative to the base 20. By adjusting the rotating rod 31 to make the transmission mechanism 32 close to or away from the base 20, the shape of the first planar linkage 34 is changed to drive the infrared heating assembly 40 to close to or away from the base 20. Specifically, when the rotating rod 31 is adjusted to make the transmission mechanism 32 rotate out relative to the base 20, the infrared heating assembly is away from the base 20; correspondingly, when the rotating rod 31 is adjusted to make the transmission mechanism 32 rotate in relative to the base 20, the infrared heating assembly is close to the base 20. Referring to Figure 3 and Figure 4 When the transmission mechanism 32 is adjusted to a certain position, the sliding block 320 moves from the initial position K1 of the sliding block to the adjusted position K2 of the sliding block, and the first planar linkage 34 moves from the initial position K5 of the first planar linkage to the adjusted position K6 of the first planar linkage. Under the cooperation of the transmission mechanism 32 and the lifting assembly 30, the infrared heating assembly moves from the initial position K3 of the infrared heating assembly to the adjusted position K4 of the infrared heating assembly 40. In some embodiments, a screw knob can be arranged on the side of the rotating rod 31 away from the sliding block, and the screw knob is connected to the rotating rod 31. Correspondingly, by rotating the screw knob clockwise by a certain angle, the transmission mechanism 32 is rotated out, and the infrared heating assembly 40 is moved from the initial position K3 of the infrared heating assembly to the adjusted position K4 of the infrared heating assembly. In particular, the rotating rod 31 and the transmission mechanism 32 are threadedly connected, and the rotating rod 31 cannot move horizontally relative to the base 20, but can only rotate in place.

[0034] In some embodiments, the transmission mechanism 32 comprises a sliding piece 320, a first transmission rod 321 and a second transmission rod 323. The rotating rod 31 is threadedly connected with the sliding piece 320, and the sliding piece 320 can be moved along the length direction of the rotating rod 31 by adjusting the rotating rod 31. The sliding piece 320 is rotationally connected with the first transmission rod 321, the first transmission rod 321 is rotationally connected with the second transmission rod 323 at the other side, and the second transmission rod 323 is connected with the first connection K7. In some embodiments, the transmission mechanism 32 is connected with the first connection K7. According to the above rotational connection relationship, the position of the sliding piece 320 can drive the change of the position of the first transmission rod 321, and further, the position of the second transmission rod 323 can be changed. Since the second transmission rod 323 is connected with the first connection K7, the above process can drive the first planar linkage mechanism 34. In some embodiments, the sliding piece 320 is provided with a threaded hole, and the rotating rod 31 can pass through the threaded hole of the sliding piece 320, so that the sliding piece 320 and the rotating rod 31 cooperate to move to adjust the position of the sliding piece 320. Through the cooperation of the transmission mechanism 32 and the first planar linkage mechanism 34, the position of the infrared heating assembly 40 connected with the first planar linkage mechanism 34 can be changed. When the user operates, only the knob of the rotating rod 31 is adjusted, the operation is simple, and the working efficiency of the infrared heating device 10 can be improved.

[0035] Referring to Figure 1 , Figure 2 and Figure 3 , in some embodiments, the first planar linkage mechanism 34 comprises a first long rod body 340 and a second long rod body 341, and a first short rod body 342 and a second short rod body 343. The first long rod body 340 and the second long rod body 341 are parallel to each other, and the first short rod body 342 and the second short rod body 343 are parallel to each other. One end of the first long rod body 340 is rotationally connected with the base 20, and the other end is rotationally connected with the first short rod body 342. One end of the second long rod body 341 is rotationally connected with the infrared heating assembly 40, and the other end is rotationally connected with the second short rod body 343. The first short rod body 342 is further rotationally connected between the two ends of the second long rod body 341, and the second short rod body 343 is further rotationally connected between the two ends of the first long rod body 340. In some embodiments, the rotational connection can be realized by bearing parts, which are used to support the rotating shaft and can effectively reduce the friction resistance to make the rotation more stable and efficient. In some embodiments, rolling bearings, sliding bearings or sliding-rolling composite bearings can be used. The first planar linkage mechanism 34 further comprises a connecting rod 345, one end of which is rotationally connected with the base 20, and the other end is rotationally connected with the first connection K7, which is the connection between the second long rod body 341 and the second short rod body 343.

[0036] When the transmission mechanism 32 acts on the first planar linkage mechanism 34, the second rotating rod simultaneously acts on the connecting rod 345, the second short rod body 343 and the second long rod body 341 due to the connection of the first connecting position K7 to the connecting rod 345, the second short rod body 343 and the second long rod body 341. Since the second short rod body 343 is arranged in parallel with the first short rod body 342 and is rotationally connected, and the second long rod body 341 is arranged in parallel with the first long rod body 340 and is rotationally connected, according to the principle of force action, at this time, the first planar linkage mechanism 34 moves in an approximately straight line in the direction perpendicular to the bottom surface, as shown in FIG. 8 and FIG. 9. Figure 4 and Figure 5 The moving track K8 of the infrared heating assembly 40 and the plumb line K9 almost coincide, so that the infrared heating assembly 40 moves in an approximately straight line in the vertical direction during the lifting process. Moreover, during the process in which the first planar linkage mechanism 34 moves in an approximately straight line within a certain stroke, the first long rod body 340 and the second long rod body 341 always maintain a parallel position, and the first short rod body 342 and the second short rod body 343 always maintain a parallel position.

[0037] In some embodiments, the base 20 is provided with a first planar linkage mechanism 34 on each of the opposite sides in the width direction, and the two ends of the second transmission rod 323 are connected to the first connecting positions K7 in the two first planar linkage mechanisms 34. In some embodiments, the first planar linkage mechanisms 34 are symmetrically arranged on the opposite sides in the width direction of the base 20. Under the action of the two first planar linkage mechanisms 34, the opposite ends of the infrared heating assembly 40 can be simultaneously lifted or lowered by the same distance, that is, under the action of the lifting assembly 30, the infrared heating assembly 40 can always be kept horizontal to the horizontal arrangement direction of the base 20, so as to keep the heating effect of the infrared heating assembly 40 on different positions of the pole piece consistent. Of course, in some embodiments, two first planar linkage mechanisms 34 can also be arranged according to actual needs, so that the two first planar linkage mechanisms move inconsistently. By arranging the first planar linkage mechanisms 34 on the opposite sides in the width direction of the base 20, the user only needs to adjust the rotating rod 31 of the infrared heating device 10 to adjust the height of the infrared heating assembly 40. Compared with the conventional way of disassembling the module to adjust the height, the present scheme can conveniently and quickly adjust the height of the infrared heating assembly 40. In some embodiments, a scale can be arranged on the first planar linkage mechanism 34, so that the height can be directly measured while the infrared heating assembly 40 is adjusted, and the distance between the infrared heating assembly 40 and the pole piece can be directly measured.

[0038] In some embodiments, the base 20 is further provided with at least two second planar link mechanisms 35, each of which is connected to the base 20 and the infrared heating assembly 40 respectively, and the positions of each first planar link mechanism 34 and the second planar link mechanism 35 on the base 20 are in a symmetrical relationship. In an embodiment, the base 20 is provided with two second planar link mechanisms 35 and two first planar link mechanisms 34, and the infrared heating device 10 has four groups of parallel planar link mechanisms with approximate linear motion, which can realize a highly approximate linear motion in a specific range, so that the lifting of the infrared heating assembly 40 is more stable, and the infrared heating assembly 40 can more efficiently heat the pole piece. In some embodiments, the first planar link mechanism 34 and the second planar link mechanism 35 can be mirror-symmetrical in structure or completely identical.

[0039] With the development of coating technology, it has been widely used in various technical fields, especially in the production of lithium batteries, which requires coating treatment of the battery pole piece. In the coating or printing of various films of lithium battery pole pieces, the oven is a main component, and infrared radiation can transfer a large amount of energy in a short time. Infrared radiators can heat large surfaces, three-dimensional shapes, and small workpieces. By customizing infrared radiators for individual applications, heating and drying processes can be integrated into various production processes. Infrared technology can easily match existing production lines, make local modifications on existing coating machines, and achieve production goals. Using infrared rays to dry and bake the pole piece is a common method, and the general infrared oven mainly places infrared heating tubes in the box 51 to achieve the heating effect of the pole piece.

[0040] Referring to Figure 6The present application provides an infrared heating coating oven 50, which comprises a box body 51, a hull 52 and the above-mentioned infrared heating device 10. The hull 52 and the infrared heating device 10 are located in the box body 51, and the hull 52 is fixed in the box body 51. The hull 52 is a long and narrow internal structure in the infrared heating coating oven, and can accommodate coating materials. The hull 52 can ensure that the coating materials remain flat and stable during drying, and avoid wrinkles or deformation. In some embodiments, the pole piece can move along the hull 52 structure, so that the pole piece is evenly heated during drying to improve the drying effect. In some embodiments, the base 20 of the infrared heating device 10 is fixed to the hull 52, so that the infrared heating device 10 is stably fixed to the hull 52. In some embodiments, the base 20 can be fixed to the hull 52 by means of buckles 21 and / or pins. The box body 51 has a drying position for placing the pole piece, and the infrared heating assembly 40 is located on one side of the base 20 close to the drying position, so as to facilitate the infrared heating assembly 40 to dry the pole piece. In some embodiments, the hull 52 comprises an upper hull 521 and a lower hull 523 located on both sides of the drying position. The infrared heating device 10 is arranged on the hull 52. The arrangement of the upper hull 521 and the lower hull 523 can arrange the infrared heating device 10 on both sides of the drying position. The upper hull 521 and the lower hull 523 are respectively provided with a plurality of infrared heating devices 10 on the side facing the drying position, which can dry the pole piece in different directions and different positions. In some embodiments, the infrared heating devices 10 of the upper hull 521 and the lower hull 523 are distributed in sequence and staggered, which can make the pole piece evenly heated. In some embodiments, the infrared heating coating oven 50 further comprises a blast nozzle 53, which can generate hot air jet in the battery pole piece oven. The hot air flow jetted out of the blast nozzle 53 can dry the pole piece. The staggered arrangement of the blast nozzle 53 and the infrared heating device 10 can make the pole piece more evenly heated, which is beneficial to improve the drying efficiency of the infrared heating coating oven 50. The infrared heating coating oven comprises the above-mentioned infrared heating device 10, i.e. the base 20, the lifting assembly 30 and the infrared heating assembly 40. The infrared heating device 10 can adjust the distance between the infrared plate and the pole piece. In the infrared heating coating oven 50, the user can conveniently and quickly adjust the distance between the infrared heating assembly 40 and the pole piece during use. The compact plane link structure is simple to operate, which effectively improves the working efficiency of the infrared heating coating oven 50.
