Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and in particular to an oven. Background Technology

[0002] Lithium-ion batteries are important energy storage devices. In the manufacturing process of lithium-ion batteries, the current collectors of the inner electrode sheets (including positive and negative electrode sheets) need to be coated with active materials. After the active materials are coated on the current collectors, the electrode sheets need to be placed in an oven to dry.

[0003] In related technologies, the sealing door of the oven is opened and closed using multiple cylinders and linkage mechanisms. The drawback of this method is that it requires a large number of driving components (i.e., cylinders), and the structure and control method are relatively complex, which can easily lead to failures, resulting in an increased equipment failure rate and affecting the production efficiency of batteries. Utility Model Content

[0004] In view of this, this application provides an oven that simplifies the drive structure of the oven's sealing door and reduces the oven's equipment failure rate.

[0009] A drive assembly is mounted on the housing. The drive assembly includes a drive component, a transmission gear, and a transmission rack. The transmission gear is fixed on the drive shaft of the drive component. The transmission rack is elastically connected to the door body and meshes with the transmission gear. The transmission rack extends along the height direction of the housing.

[0010] At least two guide members are disposed on opposite sides of the opening of the receiving cavity and extend along the height direction of the housing. The guide members are elastically connected to the door body and are used to cooperate with the rollers to define the movement path of the door assembly.

[0011] In an optional embodiment, the guide member has a guide edge for engaging with the roller, the guide edge including a first guide portion, a second guide portion, and a third guide portion connected in sequence, the first guide portion and the third guide portion both extending along the height direction of the housing, and the distance between the first guide portion and the opening of the receiving cavity is less than the distance between the third guide portion and the opening of the receiving cavity, the second guide portion being at least partially arc-shaped to allow the first guide portion and the third guide portion to smoothly connect.

[0012] In an optional embodiment, the guide further includes a first limiting portion and a second limiting portion, the first limiting portion being located at a first end of the guide and protruding outward relative to the first guiding portion, and the second limiting portion being located at a second end of the guide and protruding outward relative to the second guiding portion.

[0013] In an optional embodiment, the door includes a door body and two door connecting plates. The two door connecting plates are respectively disposed on opposite sides of the door body and are both located on the side of the door body away from the receiving cavity. The distribution direction of the two door connecting plates is perpendicular to the height direction of the box.

[0014] The door assembly also includes a plurality of elastic components disposed on the door connecting plate for connection with the transmission rack or the guide member. The extension direction of the elastic components is perpendicular to the extension plane of the door connecting plate, and the elastic components are capable of elastic deformation along their own extension direction.

[0015] In an optional embodiment, the elastic kit includes a first connector, a tension spring sleeve, and a second connector. The first connector is inserted into the tension spring sleeve and is movable along the length of the tension spring sleeve. One end of the first connector is connected to the door connecting plate. The second connector is disposed on the adjacent side of the tension spring sleeve and is used to connect with the transmission rack or the guide.

[0016] In an optional embodiment, the door body further includes a door liner located on the side of the door body near the receiving cavity, with the edge of the door liner spaced apart from the edge of the door body, and the door liner being used to extend into the receiving cavity.

[0017] In an optional embodiment, the housing is further provided with a limiting step, the limiting step surrounding the opening of the receiving cavity;

[0018] The door assembly also includes a seal that surrounds the door liner and is used to abut against the limiting step.

[0019] In an optional embodiment, the drive assembly further includes a mounting base mounted on the housing, and the drive shaft of the drive member rotatably passes through the mounting base.

[0020] In an optional embodiment, there are multiple receiving cavities and multiple driving assemblies, with the multiple receiving cavities distributed along the height direction of the housing, and the transmission racks of two adjacent driving assemblies being staggered and distributed on both sides of the receiving cavity.

[0022] The beneficial effects of the technical solution provided in this application embodiment include at least the following: Since the drive assembly includes a drive component, a transmission gear, and a transmission rack, the door assembly is driven to move through the gear and rack transmission mechanism. The structure is compact and simple, with high transmission efficiency and safety and stability. The movement of the door assembly can be achieved using a single power source, reducing the number of power sources. This not only improves transmission accuracy and reduces the failure rate of the oven, but also helps to reduce spare parts costs. By setting a guide component, and the door body being elastically connected to the guide component and the transmission rack respectively, it is ensured that the door assembly moves stably along a predetermined movement path under the cooperation of the roller and the guide component, thereby closing the receiving cavity or separating from the receiving cavity, avoiding misalignment of the door body, and improving the accuracy and stability of the door assembly movement.

Detailed Implementation

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] The directional terms used in the embodiments of this application, such as "up," "down," and "side," are generally based on the relative relationships shown in the figures. These directional terms are used merely to more clearly describe the relationships between structures, not to describe absolute directions. When the product is placed in different orientations, the orientation may change; for example, "up" and "down" may be interchanged.

[0040] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art.

[0041] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0042] like Figures 1 to 3 As shown, this application provides an oven, including a chamber body 1, a door assembly 2, a drive assembly 3, and at least two guide members 4.

[0043] For example, the oven is used to bake lithium batteries. Of course, the oven can also be applied to other fields, such as food processing, electronic product processing, ceramic processing, glass processing, pharmaceuticals, etc. This application does not make any specific limitations.

[0044] like Figure 3 As shown, the box body 1 has a receiving cavity 11, which is used to receive lithium batteries and other products that need to be processed and baked.

[0045] like Figure 2 and Figure 3 As shown, the door assembly 2 is disposed at the opening of the receiving cavity 11, for closing the receiving cavity 11 or separating from the receiving cavity 11. Figure 7 As shown, the door assembly 2 includes a door body 21 and rollers 22 disposed on the door body 21. Specifically, there are multiple rollers 22, and rollers 22 are disposed on both the left and right sides of the door body 21. By disposing of rollers 22, the movement of the door body 21 is made smoother.

[0046] When the product to be baked needs to be baked, the door assembly 2 closes the receiving cavity 11 to ensure the sealing of the receiving cavity 11 and the baking effect of the product to be baked; the door assembly 2 is separated from the receiving cavity 11 to remove or put the product to be baked.

[0047] Drive component 3 is installed on housing 1, such as Figure 4 As shown, the drive assembly 3 includes a drive member 31, a transmission gear 32, and a transmission rack 33. The transmission gear 32 is fixed on the drive shaft 35 of the drive member 31. The transmission rack 33 is elastically connected to the door body 21 and meshes with the transmission gear 32. The transmission rack 33 extends along the height direction of the housing 1.

[0048] For example, the drive element 31 is a motor, and the drive assembly 3 also includes a reducer 34 connected to the drive element 31, and the drive shaft 35 is the output shaft of the output end of the reducer 34.

[0049] The transmission gear 32 is coaxially connected to the drive shaft 35. The rotation of the drive shaft 35 drives the transmission gear 32 to rotate, which in turn drives the transmission rack 33 meshing with the transmission gear 32 to rotate. This allows the door assembly 2 to move up and down along the height direction of the box body 1, thereby closing or separating from the receiving cavity 11. Using a gear and rack transmission mechanism to drive the movement of the door assembly 2 is compact and simple in structure, has high transmission efficiency, and is safe and stable. The movement of the door assembly 2 can be achieved with a single power source, reducing the number of power sources. This not only improves transmission accuracy and reduces the failure rate of the oven, but also helps to reduce spare parts costs.

[0050] For example, the drive unit 31 is mounted on the side of the housing 1, located on one side of the receiving cavity 11 in the left-right direction, and the drive shaft 35 is along the width direction of the housing 1 (i.e., Figures 1 to 3 (Extends in the left and right directions).

[0051] like Figure 3 As shown, guide members 4 are disposed on opposite sides of the opening of the receiving cavity 11 and extend along the height direction of the housing 1. Guide members 4 are elastically connected to the door body 21 and are used to cooperate with rollers 22, thereby defining the movement path of the door assembly 2. Specifically, as... Figure 6 As shown, the transmission rack 33 is spaced apart from the guide member 4 on one side and is located outside the guide member 4. That is to say, one end of the door body 21 in the left-right direction is elastically connected to the transmission rack 33, and the other end is elastically connected to the guide member 4.

[0052] Specifically, the left and right sides of each receiving cavity 11 (i.e. Figures 1 to 3 A guide 4 is provided in each of the left and right directions (as shown in the figure) to ensure the stability of the door assembly 2 during movement.

[0053] The movement path may include a translation path that limits the vertical linear movement of the door 21, and may also include a snap-in / snap-out path that limits the movement of the door 21 to the outside or inside of the receiving cavity 11.

[0054] The door body 21 is elastically connected to the transmission rack 33 or the guide member 4. This dynamic connection relies on elastic components to ensure that the door body 21 remains fixedly connected to the transmission rack 33 / guide member 4 even during limited relative movement. This design ensures that the door body 21 remains connected to the transmission rack 33 / guide member 4 while allowing the door body 21 to move outward or inward relative to the receiving cavity 11 within a certain range, facilitating the separation of the door body 21 from or the sealing of the receiving cavity 11.

[0055] The oven provided in this embodiment has a compact and simple structure, high transmission efficiency, and is safe and stable. The drive assembly 3 includes a drive member 31, a transmission gear 32, and a transmission rack 33. The door assembly 2 is driven by the gear and rack transmission mechanism. The drive assembly 3 has a single power source to move the door assembly 2, which reduces the number of power sources. This not only improves the transmission accuracy and reduces the failure rate of the oven, but also helps to reduce the cost of spare parts. By setting the guide member 4, and the door body 21 is elastically connected to the guide member 4 and the transmission rack 33 respectively, it is ensured that the door assembly 2 moves stably along the predetermined movement path under the cooperation of the roller 22 and the guide member 4, thereby closing the receiving cavity 11 or separating from the receiving cavity 11, avoiding misalignment of the door body 21, and improving the accuracy and stability of the door assembly 2 during movement.

[0056] In a further embodiment, such as Figure 5 As shown, the guide member 4 has a guide edge 41 for engaging with the roller 22. The guide edge 41 includes a first guide portion 411, a second guide portion 412, and a third guide portion 413 connected in sequence. The first guide portion 411 and the third guide portion 413 both extend along the height direction of the housing 1. The distance between the first guide portion 411 and the opening of the receiving cavity 11 is smaller than the distance between the third guide portion 413 and the opening of the receiving cavity 11. The second guide portion 412 is at least partially arc-shaped so that the first guide portion 411 and the third guide portion 413 are smoothly connected.

[0057] like Figure 5 As shown, the upper edge of the guide member 4 is the guide edge 41. The roller 22 abuts against the guide edge 41 and moves along the guide edge 41, thus limiting the movement path of the door assembly 2 by the guide member 4. Figure 3 As shown, the guide 4 is disposed on the side of the housing 1, located outside the receiving cavity 11, and the guide edge 41 faces the front of the housing 1.

[0058] like Figure 5 As shown, both the first guide portion 411 and the third guide portion 413 have straight edges. Since the distance between the first guide portion 411 and the opening of the receiving cavity 11 is smaller than the distance between the third guide portion 413 and the opening of the receiving cavity 11, when the roller 22 abuts against the first guide portion 411, the distance between the door body 21 and the opening of the receiving cavity 11 is small, and the door assembly 2 is in a closed state, at which time the door assembly 2 closes the receiving cavity 11; when the roller 22 abuts against the third guide portion 413, the distance between the door body 21 and the opening of the receiving cavity 11 is large, and the door assembly 2 is in an open state, and the roller 22 moves along the third guide member 4, which can adjust the opening degree of the receiving cavity 11 in the height direction of the box body 1.

[0059] One end of the second guide portion 412 is connected to the first guide portion 411, and the other end is connected to the second guide portion 412. The second guide portion 412 extends in an arc shape, so that the first guide portion 411 and the second guide portion 412 are smoothly connected, ensuring that the roller 22 moves smoothly and without sticking when it moves between the first guide portion 411 and the third guide portion 413.

[0060] The opening, closing and movement of the door assembly 2 are adjusted by the first guide part 411, the second guide part 412 and the third guide part 413, which provides stable control and high positional accuracy, avoids misalignment of the fastening, and stabilizes the sealing effect.

[0061] Since the door body 21 is elastically connected to the transmission gear 32 and the guide member 4 respectively, the door body 21 can move along the front and back direction of the housing 1 and switch positions between the first guide part 411, the second guide part 412 and the third guide part 413.

[0062] Furthermore, the guide member 4 also includes a first limiting part 42 and a second limiting part 43. The first limiting part 42 is located at the first end of the guide member 4 and protrudes outward relative to the first guide part 411, and the second limiting part 43 is located at the second end of the guide member 4 and protrudes outward relative to the second guide part 412.

[0063] like Figure 5 As shown, the first limiting part 42 is located at the first end of the guide member 4 (i.e., Figure 5 The left end of the guide member 4 is located near the first guide portion 411 and protrudes upward relative to the first limiting portion 42; the second limiting portion 43 is located at the second end of the guide member 4 (i.e., the left end of the guide member 4). Figure 5 (at the right end of the middle), close to the third guide portion 413 and protruding upward relative to the third guide portion 413.

[0064] By setting the first limiting part 42 and the second limiting part 43, the extreme position of the door assembly 2 in the height direction of the housing 1 is limited, preventing the roller 22 from disengaging from the guide 4, thereby improving the stability and reliability of the cooperation between the door assembly 2 and the guide 4.

[0065] Based on any of the above embodiments, such as Figure 7 As shown, the door body 21 includes a door body 211 and two door connecting plates 212. The two door connecting plates 212 are respectively disposed on opposite sides of the door body 211, and both are located on the side of the door body 211 away from the receiving cavity 11. The distribution direction of the two door connecting plates 212 is perpendicular to the height direction of the box body 1.

[0066] The door assembly 2 also includes a plurality of elastic components 23, which are disposed on the door connecting plate 212 for connection with the driven rack 33 or guide 4. The extension direction of the elastic components 23 is perpendicular to the extension plane of the door connecting plate 212, and the elastic components 23 are capable of elastic deformation along their own extension direction.

[0067] like Figure 7 As shown, two door connecting plates 212 are located on the left and right sides of the door body 211, respectively, and are fixed to the outer surface of the door body 211. The elastic sleeve 23 and roller 22 are both mounted on the door connecting plates 212. The door connecting plates 212 and the door body 211 are positioned in the thickness direction (i.e.,...) Figure 7 The vertical drop provides a certain amount of space for the installation and movement of components such as the elastic kit 23 and the roller 22.

[0068] like Figure 7 As shown, the elastic component 23 extends in a direction perpendicular to the extension plane of the door connecting plate 212, that is, it extends in the front-back direction of the housing 1. With this arrangement, the rollers 22 on the door 21 can fit tightly against the guide edge 41. Utilizing the elastic deformation capability of the elastic component 23, the door 21 moves in the front-back direction of the housing 1, switching positions between the first guide part 411, the second guide part 412 and the third guide part 413, thereby realizing the opening, closing and moving actions of the door assembly 2.

[0069] Specifically, such as Figure 7 As shown, the elastic kit 23 includes a first connector 231, a tension spring sleeve 232, and a second connector 233. The first connector 231 is inserted into the tension spring sleeve 232 and can move along the length of the tension spring sleeve 232. One end of the first connector 231 is connected to the door connecting plate 212. The second connector 233 is disposed on the adjacent side of the tension spring sleeve 232 and is used to connect with the transmission rack 33 or the guide member 4.

[0070] The tension spring sleeve 232 contains an elastic element such as a spring. The first connecting member 231 is connected to the elastic element, allowing it to move linearly along the length of the tension spring sleeve 232. The second connecting member 233 is fixedly connected to the tension spring sleeve 232 and is used to connect to the transmission rack 33 or the guide member 4. It can be understood that the length direction of the tension spring sleeve 232 is the front-to-back direction of the housing 1.

[0071] In this embodiment, with the cooperation of the first connector 231 and the tension spring sleeve 232, the roller 22 on the door body 21 can closely follow the guide edge 41, and the door body 21 can move along the length direction of the tension spring sleeve 232 (that is, the front and rear direction of the box body 1), switching positions between the first guide part 411, the second guide part 412 and the third guide part 413, thereby realizing the opening, closing and moving actions of the door assembly 2.

[0072] In one embodiment, the door body 21 further includes a door inner liner 213, which is located on the side of the door body 211 near the receiving cavity 11, and the edge of the door inner liner 213 is spaced apart from the edge of the door body 211. The door inner liner 213 is used to extend into the receiving cavity 11.

[0073] like Figure 7 As shown, the inner door liner 213 is located inside the door body 211 (i.e., the side closest to the receiving cavity 11). The size of the door body 211 is larger than the size of the opening of the receiving cavity 11, while the size of the inner door liner 213 is smaller than or equal to the size of the opening of the receiving cavity 11. By providing the inner door liner 213, the sealing performance of the door assembly 2 when closing the receiving cavity 11 is improved.

[0074] Furthermore, the housing 1 is also provided with a limiting step 12, which surrounds the opening of the receiving cavity 11. The door assembly 2 also includes a seal 24, which surrounds the door inner liner 213 and is used to abut against the limiting step 12.

[0075] like Figure 3 As shown, the limiting step 12 is located around the opening of the receiving cavity 11 and is recessed relative to the outer wall of the front of the housing 1, forming a groove. The sealing element 24 is a sealing element such as a rubber ring, etc. Figure 7 As shown, the sealing element 24 surrounds the outer periphery of the inner liner 213.

[0076] After the inner liner 213 extends into the receiving cavity 11, the seal 24 contacts and presses against the limiting step 12, further improving the sealing performance of the door assembly 2 and the oven.

[0077] In one embodiment, the drive assembly 3 further includes a mounting base 36, which is mounted on the housing 1, and the drive shaft 35 of the drive member 31 is rotatably inserted through the mounting base 36.

[0078] Specifically, the length of the drive shaft 35 of the drive member 31 is greater than the length of the receiving cavity 11 (i.e., the receiving cavity 11 is in...). Figures 1 to 3 (Dimensions in the left and right directions) By setting a fixed seat 36, the stability of the drive shaft 35 can be improved, preventing the drive shaft 35 from shaking or shifting, thus avoiding affecting the transmission effect.

[0079] Furthermore, there are multiple receiving cavities 11, door assembly 2, and drive assembly 3. The multiple receiving cavities 11 are distributed along the height direction of the housing 1, and the transmission racks 33 of two adjacent drive assemblies 3 are staggered and distributed on both sides of the receiving cavity 11.

[0080] For example, such as Figures 1 to 3 As shown, there are three accommodating cavities 11 and three driving components 3.

[0081] In any two adjacent drive components 3, the transmission racks 33 are staggered along the left-right direction of the receiving cavity 11. That is, the transmission rack 33 of one drive component 3 is located on the left side of the receiving cavity 11, and the transmission rack 33 of the other drive component 3 is located on the right side of the receiving cavity 11. For example Figure 6As shown, in adjacent drive components 3, the transmission rack 33 of one drive component 3 is located on one side of the door body 21, and the transmission rack 33 of the other drive component 3 is located on the other side of the door body 21. This arrangement prevents the transmission racks 33 of adjacent drive components 3 from interfering with each other when the door components 2 move, ensuring that each door component 2 can open normally.

[0082] In one embodiment, the oven further includes a cover 5, which is mounted on the oven body 1 and surrounds the outside of the door assembly 2.

[0083] like Figure 1 As shown, the protective cover 5 is installed on the front of the chamber 1, which can cover the drive assembly 3, the guide 4 and other parts of the oven, so that the drive assembly 3 and the guide 4 are located inside the chamber 1. This not only helps to protect the safety of personnel and equipment and improve the space utilization of the oven, but also increases the aesthetics of the oven.

[0084] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.
