Description

Technical Field

[0001] This application relates to the technical field of battery production, and in particular to a multi-layer drying oven. Background Technology

[0002] In the battery manufacturing industry, battery cover surfaces typically require painting or adhesive coating to improve corrosion resistance, insulation performance, and aesthetics. The treated paint or adhesive layer then needs to undergo a drying and curing process to ensure it adheres firmly to the cover surface.

[0003] Traditional drying and curing equipment typically employs a single-layer tunnel structure, where products sequentially pass through heating zones on a single conveyor belt to complete the curing process. However, this single-layer conveyor structure, limited by the length of the conveyor line and the floor space required for the drying oven, can only process a limited number of products per unit time, hindering overall production efficiency. This is particularly problematic in the production of high-volume products like battery covers, where the single-layer conveyor mode struggles to meet the demands for high-efficiency production.

[0004] Chinese utility model patent with publication number CN218945537U discloses a curing oven, which has four layers of conveying components inside the oven to improve the heating and curing efficiency inside the oven; however, this curing oven requires workers to put the battery pack covers in one by one, which is not only slow in terms of loading and unloading efficiency, but also difficult to integrate with the production line for automated production. Utility Model Content

[0005] To improve the feeding efficiency of battery pack cover plates, this application provides a multi-layer drying oven.

[0006] This application provides a multi-layer drying oven, which adopts the following technical solution: A multi-layer drying oven includes a furnace body, in which a multi-layer conveying assembly is disposed; it also includes conveying racks respectively disposed on both sides of the furnace body, each conveying rack including a support frame, a shelf disposed on the support frame, a vertical drive assembly disposed on the support frame, and a horizontal movement assembly disposed on the shelf. The shelf has multiple layers, the vertical drive assembly is used to control the vertical movement of all the shelves, and the horizontal movement assembly is used to control the movement of a battery pack cover plate placed on the shelf along the length direction of the shelf.

[0007] By adopting the above technical solution, the multi-layer conveying component can realize multi-layer conveying of materials in the furnace body, thereby improving drying efficiency; the conveying rack is set on both sides of the furnace body, and the multi-layer shelf can increase the material placement capacity; the up-down drive component can control the up-down movement of all shelves, making it easy to adjust the height of the shelves to meet different operating needs; the horizontal movement component can control the battery pack cover to move along the length of the shelf, realizing the horizontal conveying of materials on the shelf, which facilitates the entry and exit of materials from the drying oven.

[0008] Optionally, the support frame includes a top support frame, a bottom support frame, and a plurality of vertical support rods disposed between the top support frame and the bottom support frame, and the bottom support frame is further provided with a plurality of support bases circumferentially.

[0009] By adopting the above technical solution, the conveyor frame of the multi-layer drying oven has a stable support structure. The top support frame, bottom support frame and vertical support rod form a frame to ensure overall stability, and the support base set around the bottom support frame further enhances the support stability of the support frame.

[0010] Optionally, the shelf is provided with guide wheels on the side facing the vertical support rod, and the guide wheels are respectively provided on two parallel sides of the vertical support rod and abut against the side wall of the vertical support rod. The guide wheels are correspondingly provided with multiple vertical support rods.

[0011] By adopting the above technical solution, the guide wheels abut against the vertical support rod during the movement of the shelf, which can play a guiding and limiting role, ensuring the stability and accuracy of the shelf's up and down movement, and reducing swaying and deviation.

[0012] Optionally, the up-down drive assembly includes a first drive rod, a first sprocket, a first chain, and a first power component. The first sprocket is rotatably mounted on the top support frame and the bottom support frame, respectively. The first chain is wound between the two first sprockets, and one end of the first chain is interconnected with all the shelves. The first drive rod is rotatably mounted on the top support frame and coaxially connected to the first sprocket. The first power component is used to control the rotation of the first drive rod.

[0013] By adopting the above technical solution, the first driving rod is rotated by the first power component, which drives the first sprocket to rotate, causing the first chain wrapped between the two first sprockets to rotate, thereby driving all the shelves connected to one end of the first chain to move up and down, thus achieving stable control of the up and down position of the shelves.

[0014] Optionally, a drive block is detachably provided on the shelf, and the first chain passes through the drive block and is fixedly connected to the drive block.

[0015] By adopting the above technical solution, the connection between the shelf and the first chain becomes more flexible, making it easier to repair or replace the shelf or the first chain later.

[0016] Optionally, the first power component includes a first motor, a worm gear, and a worm wheel. The first sprocket and the first chain are respectively disposed at both ends of the support frame. The two first sprockets located on the top support frame are connected by the first drive rod. The worm wheel is coaxially sleeved on the side wall of the first drive rod. The worm gear is rotatably disposed on the top support frame and meshes with the worm wheel. The output shaft of the first motor is connected to the worm gear.

[0017] By adopting the above technical solution, the first drive rod is driven to rotate by the cooperation of the first motor, worm gear and worm wheel, which in turn drives the first sprocket and the first chain to move up and down, so as to realize the up and down movement of the shelf. This transmission method has the advantages of smooth transmission and can accurately control the movement position of the shelf.

[0018] Optionally, the horizontal movement assembly includes a second drive rod, a second chain, a second sprocket, and a second power component. A second sprocket is rotatably mounted at both ends of the shelf, and the second chain is wound around the second sprockets at both ends. The second sprocket and the second chain are respectively mounted on both sides of the shelf, with the upper surfaces of the two second chains located on the same plane. The second sprockets on both sides of the shelf are connected by a second drive rod. The second power component is used to drive the second sprocket to rotate.

[0019] By adopting the above technical solution, the conveyor frame of the multi-layer drying oven can use the second power component to drive the second sprocket to rotate, thereby driving the second chain wrapped around it to move, thus controlling the battery pack cover plate placed on the shelf to move along the length of the shelf. The two second sprockets are connected by the second drive rod and the upper surfaces of the two second chains are located on the same plane, which can ensure that the battery pack cover plate moves smoothly and realize the horizontal conveying function of the battery pack cover plate on the shelf.

[0020] Optionally, positioning frames are provided on both side walls of the shelf, and the positioning frames are used to support the second chain.

[0021] By adopting the above technical solution, positioning frames that support the second chain are set on both sides of the rack of the multi-layer drying oven, which can ensure the stable operation of the second chain and prevent it from shaking or shifting during operation, thereby ensuring that the battery pack cover can move smoothly along the length of the rack.

[0022] Optionally, a plurality of support rollers are rotatably provided between the two positioning frames.

[0023] By adopting the above technical solution, a support roller is set between the two positioning frames, which can provide auxiliary support for the battery pack cover, reduce the shaking and deformation of the second chain during operation, and improve the stability of the battery pack cover moving horizontally on the shelf.

[0024] In summary, this application includes at least one of the following beneficial effects: 1.

[0027] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0028] This application discloses a multi-layer drying oven. (Refer to...) Figure 1 The drying oven includes a furnace body 1 and conveyor frames 3 respectively disposed on both sides of the furnace body 1. The furnace body 1 is equipped with a multi-layer conveyor assembly 2, which can simultaneously dry the battery pack cover plates located on the conveyor assembly 2. The structure of the multi-layer conveyor assembly 2 has been fully disclosed in the prior art and will not be described in detail in this application. The conveyor frame 3 cooperates with the furnace body 1 and can accurately convey the battery pack cover plates to the multi-layer conveyor assembly 2 of the furnace body 1, realizing multi-layer simultaneous drying operation, improving drying efficiency, and adapting to automated production.

[0029] Reference Figure 1 and Figure 2Specifically, the conveyor frame 3 includes a support frame 4, a shelf 5, an up-and-down drive assembly 6, and a horizontal movement assembly 7. The support frame 4 includes a top support frame 41, a bottom support frame 42, and several vertical support rods 43. Both the top support frame 41 and the bottom support frame 42 are rectangular structures, with their length parallel to the width of the furnace body 1. The vertical support frames are fixed between the top support frame 41 and the bottom support frame 42 by welding or bolts. Several support bases 44 are also circumferentially arranged on the bottom support frame 42. Rubber pads can be installed on the bottom of the support bases 44 to provide shock absorption and anti-slip properties. In other embodiments, pulleys with brakes can also be installed on the bases to facilitate the movement of the conveyor frame 3.

[0030] The shelving unit 5 has a rectangular frame structure, with multiple shelving units spaced apart along the vertical direction on the support frame 4. To accommodate the furnace body 1, the number of shelving units 5 and the distance between adjacent shelving units 5 are configured one-to-one with the conveying components 2 inside the furnace body 1. The vertical drive component 6 is used to control the simultaneous vertical movement of all shelving units 5; the horizontal movement component 7 is used to feed the battery pack cover plate on the shelving unit 5 onto the conveying component 2 inside the furnace body 1.

[0031] Reference Figure 1 and Figure 2 In this embodiment, the vertical support rod 43 can be made of hollow square steel or angle steel, etc. The length of the shelf 5 can be greater than the width of the support frame 4, thus extending out of the support frame 4 at both ends. Guide wheels 51 are provided on the outer side of the long side of the shelf 5; and corresponding to each vertical support rod 43, the guide wheels 51 are respectively provided on two parallel side walls of the vertical support rod 43 and abut against the side walls of the vertical support rod 43. The provision of guide wheels 51 makes the shelf 5 more stable when moving up and down, reducing swaying and offset.

[0032] Reference Figure 2 and Figure 3 In this embodiment, the up-and-down drive assembly 6 includes a first drive rod 61, a first sprocket 62, a first chain 63, and a first power component 64. The first sprocket 62 is rotatably mounted on the top support frame 41 and the bottom support frame 42, respectively, and can be installed by setting a support; the first chain 63 is vertically wound between the two first sprockets 62, and one end of the first chain 63 is interconnected with all the shelves 5, so that when the first chain 63 rotates, it can drive all the shelves 5 to move up and down synchronously.

[0033] Along the length of the support frame 4, a first sprocket 62 and a first chain 63 are respectively disposed at both ends of the support frame 4. A first drive rod 61 is rotatably mounted on the top support frame 41 and coaxially connected to the two first sprockets 62 located on the top support frame 41. Thus, when the first power component 64 controls the rotation of the first drive rod 61, it can drive the two first chains 63 to rotate synchronously. The first power component 64 includes a first motor 641, a worm gear 642, and a worm wheel 643. The worm wheel 643 is coaxially sleeved on the side wall of the first drive rod 61. The worm gear 642 is rotatably mounted on the top support frame 41 and meshes with the worm wheel 643. The first motor 641 is mounted on the top support frame 41 by bolts or other means, and the output shaft of the first motor 641 is connected to the worm gear 642. In actual use, the worm wheel 643 and worm gear 642 can be lubricated by solid lubricating oil or by setting up a closed lubrication system for lubrication.

[0034] When the first motor 641 starts, it drives the worm gear 642 to rotate, which in turn drives the worm wheel 643 to rotate, thereby causing the first drive rod 61 to rotate. The first drive rod 61 drives the first sprockets 62 at both ends to rotate, which in turn causes the two first chains 63 to move synchronously, thus realizing the up and down movement of the shelf 5.

[0035] Reference Figure 2 and Figure 3 A drive block 52 is detachably fixed to the side wall of the shelf 5 facing the vertical support rod 43. The first chain 63 passes through the drive block 52 and is fixedly connected to it. The drive block 52 can be connected to the shelf 5 by bolts, which is convenient for disassembly and installation, and facilitates equipment maintenance and repair.

[0036] Reference Figure 2 and Figure 4 In this embodiment, the horizontal moving component 7 includes a second drive rod 71, a second chain 72, a second sprocket 73, and a second power component 74. At both ends of the shelf 5, i.e., the ends of the shelf 5 closest to and furthest from the furnace body 1, a second sprocket 73 is rotatably mounted, and a second chain 72 is wound around the second sprockets 73 at both ends. The second sprockets 73 and the second chain 72 are respectively mounted on both sides of the shelf 5, with the upper surfaces of the two second chains 72 located on the same plane. The second sprockets 73 on both sides of the shelf 5 are connected by the second drive rod 71. The second power component 74 is used to drive the second sprockets 73 to rotate. When the second power component 74 is activated, it drives the second sprockets 73 to rotate, causing the second chain 72 to move, thereby enabling the battery pack cover placed on the shelf 5 to move along the length of the shelf 5.

[0037] The second power component 74 can be a second motor. The second motor can also be fixed to the side wall of the shelf 5 by bolts or other means. Its output shaft is coaxially connected to the second sprocket 73, thereby controlling the rotation of the second sprocket 73.

[0038] Furthermore, positioning frames 53 are fixed to the two adjacent side walls of the shelf 5 by welding or bolts. The positioning frames 53 are located within the second chain 72 and serve to support the second chain 72. Furthermore, several support rollers 54 are rotatably arranged between the two positioning frames 53. The upper surface of the support rollers 54 is on the same plane as the upper surface of the second chain 72, or the upper surface of the support rollers 54 may be slightly lower than the upper surface of the second chain 72. When the battery pack cover is fed onto the shelf 5, it can be conveyed via the second chain 72. The support rollers 54 provide support, reducing the pressure on the second chain 72.

[0039] The implementation principle of a multi-layer drying oven according to an embodiment of this application is as follows: When the drying oven is in use, the first motor 641 is started to control the multi-layer racks 5 to move downwards until the top rack 5 is on the same plane as the conveyor belt on the production line. Then, the battery pack cover is sent into the rack 5. At the same time, the second motor is started to move the battery pack cover to the center position of the rack 5. Then, the racks 5 are controlled to move upwards so that the battery pack cover can enter the second rack 5. This process is repeated until all racks 5 are equipped with battery pack covers. The racks 5 are moved up and down so that they correspond one-to-one with the multi-layer conveyor components 2 in the oven body 1. At this time, all battery pack covers on all racks 5 are sent into the oven body 1 for drying.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
