Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production and processing equipment, in particular to an automatic door for a battery cooling furnace. Background Art

[0002] At present, the lithium battery industry at home and abroad has a good development prospect. Lithium-ion batteries have been widely used in portable appliances such as laptops, cameras, and mobile communications due to their unique performance advantages. The large-capacity lithium-ion batteries currently developed have begun to be tried in electric vehicles and are expected to become one of the main power sources for electric vehicles in the 21st century. They will also be used in artificial satellites, aerospace, and energy storage. With the shortage of energy and the pressure of environmental protection in the world, lithium batteries are now widely used in the electric vehicle industry, especially the emergence of lithium iron phosphate batteries, which has further promoted the development and application of the lithium battery industry. In this regard, in order to ensure the high quality of lithium batteries, it is necessary to strictly control the production environment of each process in the lithium battery production process.

[0003] In the production process of lithium batteries, a lithium battery drying furnace is required to dry the battery shell, pole piece, pole coil and battery cell. Among them, the lithium battery drying furnace mainly includes thermal radiation heating, hot air heating and contact heating. Due to the problems of poor heating uniformity, long baking cycle and high energy consumption of radiation heating and hot air heating, the industry has basically replaced them with contact heating. Contact heating is favored by battery manufacturers because the heating plate directly contacts the battery surface, the temperature uniformity is good and the baking cycle is short. Subsequently, the lithium battery after drying often has a temperature higher than normal temperature. Therefore, rapid cooling is required to meet the process production requirements and obtain qualified lithium battery products.

[0004] In the process of cooling the battery, the existing cooling method is to use a battery cooling furnace for cooling and lowering the temperature, wherein the battery cooling furnace includes a door panel assembly, and the door panel assembly is used to close the cooling cavity in the cooling furnace. Specifically, the existing door panel assembly generally includes a flexible door panel, a connecting rod, a reflector, a guide rail, a translation cylinder, a rotating cylinder, etc., and the rotating cylinder is combined with the connecting rod to generate a lifting force for moving the flexible door panel in the vertical direction, and at the same time, the translation cylinder is combined with the guide rail to generate a thrust in the horizontal direction on the flexible door panel, so that the flexible door panel is rotated relative to the cooling furnace through the combination of the lifting force and the horizontal thrust. It can be seen from the above-mentioned components of the door panel assembly that the existing door panel assembly has a relatively complex structure, which brings a certain burden to the installation and assembly of the door panel assembly. At the same time, the working principle of the existing door panel assembly is relatively cumbersome, which brings certain troubles to the operator. In addition, due to the overly complex structure and large number of components of the door panel assembly, the production cost of the door panel assembly is relatively high.

[0005] Therefore, it is necessary to propose an automatic door for a battery cooling furnace to improve the above-mentioned defects. Utility Model Content

[0026] The present invention is further described below in conjunction with the accompanying drawings and implementation modes:

[0027] It should be noted that the existing battery cooling furnace opens or closes the cooling chamber through a door panel assembly. Specifically, the door panel assembly includes a door panel, a connecting rod, a guide rail, a translation cylinder, a rotating cylinder, etc., and it is necessary to drive the translation cylinder to drive the guide rail, and at the same time, it is necessary to drive the rotating cylinder to drive the connecting rod to drive the door panel to rotate to open or close the cooling chamber. This leads to more complex structural components of the door panel assembly, and also leads to the overly complex operating principle of the overall structure of the door panel assembly, and increases the production cost of the door panel assembly. In order to adjust the above defects, the present application proposes an automatic door for a battery cooling furnace.

[0028] like Figure 1-3 As shown, the utility model proposes an automatic door for a battery cooling furnace, including a door panel 10, and also includes a transmission member 20, a first connecting member 30, a second connecting member 40 and a driving module 50, wherein the first connecting member 30 and the second connecting member 40 are respectively located at both ends of the transmission member 20, the door panel 10 is located between the first connecting member 30 and the second connecting member 40, and the transmission member 20 is connected and fixed to the door panel 10, the first connecting member 30 and the second connecting member 40 are respectively connected and fixed to the battery cooling furnace, in addition, the driving module 50 is connected and fixed to the second connecting member 40, and the driving module 50 is transmission-connected to the transmission member 20, and the driving module 50 is used to drive the transmission member 20 to rotate.

[0029] In this embodiment, reference Figure 1 and Figure 2A cooling chamber is provided in the battery cooling furnace. The utility model is used to close or open the opening of the cooling chamber, so as to facilitate the placement of dried batteries and fixtures into the cooling chamber. Specifically, the automatic door includes a rectangular door panel 10, a transmission member 20 is provided above the door panel 10, and the axial direction of the transmission member 20 is parallel to the direction of the upper side of the door panel 10, wherein the axial length of the transmission member 20 is greater than the length of the door panel 10, the first connecting member 30 and the second connecting member 40 are respectively arranged at both ends of the transmission member 20, and the two ends of the transmission member 20 are respectively connected to the first connecting member 30 and the second connecting member 4 0 transmission connection, more specifically, the first connecting member 30 and the second connecting member 40 are respectively fixedly connected with the battery cooling furnace by bolts. In addition, a driving module 50 is provided at one end of the second connecting member 40, and the driving module 50 is fixedly connected with the second connecting member 40. The driving module 50 is controlled to drive the transmission member 20 to rotate, thereby driving the door panel 10 between the first connecting member 30 and the second connecting member 40 to rotate around the axis of the transmission member 20 with the same amplitude, thereby controlling the door panel 10 to flip relative to the first connecting member 30 and the second connecting member 40, so as to realize the closing and opening of the cooling cavity opening.

[0030] It needs to be explained that the utility model drives the transmission member 20 through the driving module 50 to drive the door panel 10 to rotate relative to the first connecting member 30 and the second connecting member 40, so as to close and open the opening of the cooling chamber. Compared with the door panel 10 assembly of the existing cooling furnace, the structural components of the utility model are simpler and the working principle is simpler. At the same time, the production cost of the utility model is lower than that of the existing door panel 10 assembly.

[0031] For further reference, Figure 1 and Figure 2 The transmission member 20 includes a transmission rod 21 and a plurality of clamping blocks 22 . A clamping groove 221 is provided at one end of the clamping block 22 . A clamping position 211 matching the clamping groove 221 is provided on the transmission rod 21 .

[0032] In this embodiment, reference Figure 2The transmission member 20 includes three clamping blocks 22. Specifically, a clamping groove 221 is provided on the upper end surface of the clamping block 22, and the cross section of the clamping groove 221 is similar to a U shape. Specifically, the transmission rod 21 is cylindrical as a whole, wherein clamping positions 211 are respectively provided on both sides of the transmission rod 21, so that the part of the transmission rod 21 with the clamping position 211 is adapted to the clamping groove 221 of the clamping block 22, so that the transmission rod 21 is in abutment with one end of the clamping block 22, and the transmission rod 21 and the clamping block 22 are also reinforced and connected by screws. In addition, the other end of the clamping block 22 is connected to the door panel 10. It should be explained that the structural setting of the clamping groove 221 and the clamping position 211 can improve the stability of the connection structure between the transmission rod 21 and the clamping block 22, thereby avoiding the problem of slipping of the clamping block 22 and the transmission rod 21 when the door panel 10 and the clamping block 22 rotate around the axis of the transmission rod 21.

[0033] For further reference, Figure 1 and Figure 2 The other end of the clamping block 22 is provided with a right-angle clamping position 222 , and the right-angle clamping position 222 is adapted to the side surface of the door panel 10 , and the clamping block 22 is connected and fixed to the door panel 10 .

[0034] In this embodiment, reference Figure 2 The lower end surface of the clamping block 22 is provided with a right-angled position 222. Specifically, both side edges of the upper end surface of the door panel 10 are right-angled sides. The other end of the clamping block 22 is clamped with the door panel 10 through the right-angled position 222, and the door panel 10 and the clamping block 22 are connected and fixed by screws. It should be explained that the structural setting of the right-angled position 222 can improve the stability of the connection structure between the clamping block 22 and the door panel 10.

[0035] For further reference, Figure 1 and Figure 3 The first connecting member 30 includes a first fixed seat 31 and a telescopic limit member 32 connected to the first fixed seat 31. The first fixed seat 31 is provided with a limit groove 311. In addition, one end of the transmission rod 21 is rotatably connected to the first fixed seat 31. One end of the transmission rod 21 is also provided with a limit protrusion 212 installed in the limit groove 311. The telescopic limit member 32 is used to limit the limit protrusion 212 in the limit groove 311 that rotates with the transmission rod 21.

[0036] In this embodiment, reference Figure 1 and Figure 3The first fixed seat 31 is fixed to the cooling furnace by screws. In addition, one end of the transmission rod 21 is arranged through the first fixed seat 31, and the transmission rod 21 is rotatably connected to the first fixed seat 31 through a bearing. A limiting groove 311 is provided on the first fixed seat 31, and the transmission rod 21 is arranged through the limiting groove 311, and the limiting protrusion 212 is located in the limiting groove 311, so that when the transmission rod 21 rotates, the limiting protrusion 212 is driven to flip around the axis of the transmission rod 21 in the limiting groove 311. Specifically, the telescopic limiting member 32 includes a telescopic cylinder and a folding rod connected to the output end of the telescopic cylinder. A limiting cylinder is provided on the folding rod, and the limiting cylinder is telescopically arranged through the limiting groove 311. Further specifically, the telescopic cylinder The cylinder is connected and fixed with screws on the upper end surface of the first fixed seat 31, and the telescopic cylinder is controlled to drive the folding rod to telescopically move, thereby driving the limiting cylinder to extend into the limiting groove 311 or leave the limiting groove 311. Through the structural setting of the telescopic limiting member 32, the flipping angle of the limiting protrusion 212 can be limited by the limiting cylinder, thereby reversely limiting the self-rotation amplitude of the transmission rod 21, and then controlling the flipping angle of the door panel 10. At the same time, since the door panel 10 is heavy and large in size, the flipping angle of the door panel 10 can be limited through the structural setting of the limiting protrusion 212 and the telescopic limiting member 32, thereby improving the safety of the utility model to a certain extent and avoiding the risk of the heavy door panel 10 falling automatically.

[0037] It should be supplemented that, in the present embodiment, the telescopic limiting member 32 is located in the middle of the limiting groove 311 to limit the turning of the limiting protrusion 212, so that the limiting protrusion 212 turns within the range of 0° to 90°.

[0038] For further reference, Figure 1 and Figure 3 The first connecting member 30 includes a photoelectric limit member 33, which includes a plurality of photoelectric modules 331, a partition plate 332 and a connecting plate 333. The photoelectric module 331 is connected to the connecting plate 333, and the connecting plate 333 is connected to the first fixed seat 31. In addition, the partition plate 332 is connected to the door panel 10 and rotates with the door panel 10 at the same amplitude, and the position path of the plurality of photoelectric modules 331 matches the rotation path of the partition plate 332.

[0039] In this embodiment, reference Figure 1 and Figure 3The photoelectric stopper 33 includes two photoelectric modules 331. Specifically, the connecting plate 333 is located at one end of the transmission rod 21 and at one side of the first fixing seat 31, wherein the connecting plate 333 is screwed and fixed to the first fixing seat 31, and the connecting plate 333 is semicircular in shape. The photoelectric module 331 is located on the side of the connecting plate 333 away from the first fixing seat 31, and the photoelectric module 331 is screwed and fixed to the connecting plate 333. Further specifically, the two photoelectric modules 331 overlap in the vertical direction, that is, the angle between the photoelectric modules 331 is 180°, and an interception channel is provided on the photoelectric module 331. In addition, The partition plate 332 is fixedly connected to the door panel 10 by screws. When the door panel 10 is flipped around the axis of the transmission rod 21, specifically, when the opening of the cooling chamber is fully opened, the door panel 10 is in a vertical state and is set toward the upper end. At this time, the partition plate 332 is located at the interception channel of the photoelectric module 331 at the upper end of the connecting plate 333. In this state, the door panel 10 can be said to be at 0°. In another state, when the opening of the cooling chamber is fully closed, the door panel 10 is in a vertical state and is set toward the lower end. At this time, the partition plate 332 is located at the interception channel of the photoelectric module 331 at the lower end of the connecting plate 333. In this state, the door panel 10 can be said to be at 180°. It should be explained that, through the structural setting of the photoelectric limiter 33, a rotation angle reference can be provided for the self-rotation of the transmission rod 21 driven by the drive module 50, and a stop command can be issued in time to avoid excessive rotation angle of the transmission rod 21 and extrusion damage to the cooling furnace by the door panel 10.

[0040] For further reference, Figure 1 and Figure 2 The second connecting member 40 includes a second fixed seat 41, a first gear 42 and a second gear 43. The other end of the transmission rod 21 is rotatably connected to the second fixed seat 41, and the transmission rod 21 passes through the second fixed seat 41 and is connected to the first gear 42. The first gear 42 is meshingly connected to the second gear 43, and the second gear 43 is transmission-connected to the output end of the driving module 50.

[0041] In this embodiment, reference Figure 2The second fixed seat 41 is fixed to the cooling furnace by screws. In addition, the driving module 50 can be a servo motor. Specifically, the other end of the transmission rod 21 is rotatably connected to the second fixed seat 41 through a bearing, and the other end of the transmission rod 21 is arranged through the second fixed seat 41. Further specifically, the driving module 50 is located on the side of the second fixed seat 41 away from the first fixed seat 31, and the first gear 42 and the second gear 43 are located between the second fixed seat 41 and the driving module 50, wherein the other end of the transmission rod 21 is connected to the first gear 42, and the second gear 43 is connected and fixed to the output end of the driving module 50, combined with the meshing transmission link of the first gear 42 and the second gear 43, so that through the structural setting of the first gear 42 and the second gear 43, the utility model can drive the transmission rod 21 to rotate by controlling the driving module 50, combined with the structural setting of the gear, it can be avoided that when the driving module 50 stops, under the action of the gravity of the door panel 10, the upward resistance to the door panel 10 can be generated by gear meshing, thereby reducing the risk factor of the door panel 10 automatically falling.

[0042] For further reference, Figure 1 and Figure 2 The second connecting member 40 further includes a sleeve seat 44 , on which a transmission groove 441 for mounting the first gear 42 and the second gear 43 is provided. In addition, the driving module 50 is connected to the sleeve seat 44 , and the sleeve seat 44 is connected and fixed to the second fixing seat 41 .

[0043] In this embodiment, reference Figure 2 The socket 44 is located between the second fixed seat 41 and the driving module 50. Specifically, one side of the socket 44 is fixed to the driving module 50 by screws, and the other side is fixed to the second fixed seat 41 by screws. It should be explained that through the structural setting of the socket 44, the first gear 42 and the second gear 43 can be protected, thereby improving the service life of the utility model to a certain extent.

[0044] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.

[0045] The above is an exemplary description of the utility model patent in conjunction with the accompanying drawings. It is obvious that the implementation of the utility model patent is not limited to the above-mentioned method. As long as various improvements are made by adopting the method concept and technical solution of the utility model patent, or the concept and technical solution of the utility model patent are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
