Description

Technical Field

[0002] In the related art, the front and back sides of the electrode after coating usually need to be dried in an oven. A electrode channel is formed between the upper hull and the lower hull of the oven for the electrode to pass through after coating. The electrode can enter the electrode channel and be kept in a suspended state by the airflow provided by the upper hull and the lower hull, so that the front and back sides of the electrode can be heated by the heating component in the oven.

DETAILED DESCRIPTION

[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] In the description of the present invention, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0034] In the description of the present utility model, "several" means more than one, "many" means more than two, "greater than", "less than", "exceed" etc. are understood to exclude the number itself, and "above", "below", "within" etc. are understood to include the number itself. If there is a description of "first" or "second", it is only used to distinguish the technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0035] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0036] In the description of the utility model, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0037] In conventional technology, in order to adjust the height of the upper hull and the lower hull, adjusting bolts are usually set at multiple positions of the upper hull and the lower hull, and nuts that match the adjusting bolts are set on the frame; the staff adjusts the specific heights of multiple positions of the upper hull and the lower hull by rotating the adjusting bolts at different positions; since the staff can only adjust one adjusting bolt at a time, the staff needs to rotate all the adjusting bolts set on the hull to make the hull rise or fall as a whole; and in the process of rotating the adjusting bolts, the adjusting bolt being rotated will move relative to other adjusting bolts, and the adjusting bolt being rotated will drive a part of the hull to move together, so that a part of the hull is warped relative to another part, and in order to avoid plastic deformation of the hull, the travel of movement needs to be limited each time the adjusting bolt is rotated, resulting in that when the actual height of the hull is too different from the preset height, the height of each part of the hull cannot reach the preset height by only one adjustment; the staff needs to rotate the adjusting bolts at different positions one by one for multiple times to make the hull reach the preset height. On the other hand, the deformation of the hull itself will also increase the force that the adjusting bolt needs to be subjected to when it is rotated, making the adjustment more difficult.

[0038] Please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, in view of the above situation, the utility model proposes an oven, including a hull assembly 100 and a lifting device 200; the hull assembly 100 includes an upper hull 110 and a lower hull 120, and the upper hull 110 and the lower hull 120 define a pole piece channel 130 for the pole piece to pass through; the lifting device 200 includes a driving assembly 210 and a plurality of lifting units 220; each lifting unit 220 includes at least one adjusting member 222, and each lifting unit 220 is connected to the driving assembly 210, and the driving assembly 210 is used to drive each adjusting member 222 to rise and fall synchronously along the support rod 221.

[0039] It should be noted that the specific power form of the driving assembly 210 for driving the adjusting member 222 to synchronously rise and fall can be a hand wheel driven by human power, or an electrical device such as a cylinder or a motor. On the other hand, in the manner of using the driving assembly 210 to drive the adjusting member 222 to rise and fall, according to some embodiments of the utility model, the lifting unit 220 includes a connecting rod mechanism, the adjusting member 222 is connected to the connecting rod mechanism, and the driving assembly 210 drives the connecting rod mechanism to lift the adjusting member 222; according to other embodiments of the utility model, the lifting unit 220 includes a pulley mechanism, the adjusting member 222 is connected to the connecting rod mechanism, and the driving assembly 210 drives the connecting rod mechanism to lift the adjusting member 222.

[0040] Without departing from the inventive concept of the utility model, those skilled in the art may also use other mechanical structures to realize the lifting and lowering of the adjusting member 222; as a preferred solution, each lifting unit 220 further includes a support rod 221, the support rod 221 extends in the up-down direction, the adjusting member 222 is connected to the support rod 221, and the driving assembly 210 is used to drive each adjusting member 222 to rise and fall synchronously along the support rod 221. The synchronous lifting and lowering of the adjusting member 222 along the up-down direction of the support rod 221 is more conducive to reducing the shaking of the adjusting member 222 in the horizontal direction during the lifting process, so that the lifting process of the adjusting member 222 is more stable.

[0041] As for the specific form of the lifting and lowering of the adjusting member 222 relative to the support rod 221, according to some embodiments of the utility model, a guide rail is provided on the support rod 221, and a slider matching the guide rail is provided on the adjusting member 222, and the driving assembly 210 directly drives the adjusting member 222 to lift and lower relative to the support rod 221; as a preferred solution, according to other embodiments of the utility model, the adjusting member 222 is threadedly connected to the support rod 221, and the driving assembly 210 is used to rotate the support rod 221 itself so that the adjusting member 222 threadedly connected to the support rod 221 can be lifted and lowered. The above solution can make the movement of the adjusting member 222 relative to the support rod 221 more stable, and when the adjusting member 222 does not need to be lifted and lowered, the driving assembly 210 does not need to continuously drive the lifting unit 220 to enable the adjusting member 222 to stably stay on the support rod 221.

[0042] The adjusting parts 222 in at least three of the lifting units 220 are connected to the upper hull 110, the lifting units 220 are distributed on both sides of the hull assembly 100 in the width direction, and the multiple lifting units 220 located on the same side are arranged along the length direction of the hull assembly 100; and / or, the adjusting parts 222 in at least three of the lifting units 220 are connected to the lower hull 120, and the lifting units 220 are distributed on both sides of the hull assembly 100 in the width direction, and the multiple lifting units 220 located on the same side are arranged along the length direction of the hull assembly 100.

[0043] It should be understood that when the lifting units 220 are distributed on both sides of the hull assembly 100 in the width direction, and multiple lifting units 220 located on the same side are arranged along the length direction of the hull assembly 100, the hull can form a stable connection relationship with the lifting device 200 through three adjusting parts 222, and when the three adjusting parts 222 connected to the same hull move up and down synchronously, the hull can be driven to move up and down.

[0044] Through the above scheme, since the driving component 210 can drive the adjusting members 222 of multiple lifting units 220 to rise and fall at the same time, each adjusting member 222 connected to the same hull remains relatively still during the lifting process, the hull connected to at least three adjusting members 222 can be lifted and lowered synchronously with the adjusting members 222, and relative warping will not occur between different parts of the hull connected to the adjusting members 222, thereby preventing the adjusting members 222 from damaging the hull connected to the adjusting members 222 during the lifting process; on the other hand, the above scheme can also save the force added to a single adjusting member 222 due to the deformation of the hull, making it easier to adjust the height of the hull.

[0045] Without departing from the inventive concept of the present utility model, those skilled in the art may arrange more lifting units 220 .

[0046] For further information, please refer to Figure 1 , Figure 2 , Figure 5 As shown, the lifting device 200 includes at least four lifting units 220; at least two adjusting members 222 are connected to both sides of the upper hull 110 along the width direction; and / or at least two adjusting members 222 are connected to both sides of the lower hull 120 along the width direction. Through the above scheme, both sides of the hull can be supported by multiple lifting units 220, further enhancing the connection stability between the hull and the lifting device 200, and also contributing to the stability of the hull during the lifting process.

[0047] Specifically, according to some embodiments of the present invention, the lifting device 200 includes four lifting units 220, and the adjusting members 222 of the four lifting units 220 are respectively connected to the upper hull 110 in the width direction (ie Figure 1 The adjusting members 222 on both sides of the upper hull 110 are symmetrically arranged relative to the upper hull 110 in the left-right direction (as shown in the figure). It should be understood that the adjusting members 222 on both sides in the width direction of the hull are symmetrically arranged relative to the hull, which facilitates those skilled in the art to adjust the various structural dimensions in the lifting device 200; on the other hand, since the upper hull 110 itself is a symmetrical structure and the axis of symmetry is parallel to the length direction of the upper hull 110, the adjusting members 222 on both sides in the width direction of the hull are symmetrically arranged relative to the hull, which can further enhance the stability of the hull in a stationary state.

[0048] As mentioned above, the specific power form used for the drive assembly 210 can be a hand wheel driven by human power, or an electric drive device such as a cylinder, a motor, etc. For the solution that the drive assembly 210 drives multiple adjustment members 222 to rise and fall synchronously along the support rod 221 by power, in some embodiments, the drive assembly 210 includes a signal circuit and multiple electric drive devices, and the oven controls the multiple electric drive devices through the signal circuit, so that each electric drive device adjusts the adjustment member 222 on a lifting unit 220, and synchronizes the lifting action of each adjustment member 222 through the signal circuit; in some embodiments, the drive assembly 210 includes an electric drive device, and the electric drive device drives multiple lifting units 220 through the transmission of the mechanical structure.

[0049] For further information, please refer to Figure 1 , Figure 2 The driving assembly 210 shown includes a driving element 211 and a transmission member 213, wherein the transmission member 213 is connected to the driving element 211, and the driving element 211 is used to provide power; at least one lifting unit 220 is connected to the transmission member 213. Through the above scheme, the power of the driving element 211 can be transmitted to multiple lifting units 220 through the transmission member 213, which effectively reduces the number of driving elements 211 and reduces the cost of the driving assembly 210. According to some embodiments of the utility model, the transmission member 213 can use mechanical structures such as synchronous belts and gears to drive the lifting units 220. It should be noted that the specific power form of the driving element 211 can be a hand wheel driven by human power, or an electrical drive device such as a cylinder or a motor.

[0050] As a preferred solution, the driving assembly 210 includes at least two transmission members 213. Through the above solution, the power of the driving element 211 can be transmitted to the multiple lifting units 220 through the multiple transmission members 213; compared with the solution in which the driving element 211 is transmitted to the multiple lifting units 220 through a single transmission member 213, driving through multiple transmission members 213 can simplify the design of a single transmission member 213 and reduce the manufacturing difficulty of the transmission member 213.

[0051] Exemplarily, for the lifting units 220 distributed on both sides in the width direction of the hull, the driving element 211 controls the lifting units 220 distributed on both sides in the width direction of the hull respectively through two transmission members 213. Specifically, according to some embodiments of the utility model, two lifting units 220 are respectively arranged on both sides of the upper hull 110 in the width direction, and the lifting units 220 located on the same side are arranged along the length direction of the upper hull 110; one transmission member 213 is simultaneously connected to the two lifting units 220 on one side in the width direction of the hull, and the other transmission member 213 is simultaneously connected to the two lifting units 220 on the other side in the width direction of the hull; the driving element 211 can simultaneously drive the two transmission members 213 to drive each lifting unit 220.

[0052] According to some embodiments of the present invention, please refer to Figure 1 , Figure 2 As shown, the driving assembly 210 may further include four transmission members 213, each of which is individually connected to a lifting unit 220. By driving four lifting units 220 in a one-to-one correspondence through four transmission members 213, the design of a single transmission member 213 can be further simplified.

[0053] It should be noted that the driving element 211 can be directly connected to multiple transmission parts 213, for example, a common transmission structure of gears and pulleys can be directly set at the output end of the driving element 211 to achieve synchronous driving of multiple transmission parts 213 by the driving element 211; the driving element 211 can also be indirectly connected to multiple transmission parts 213.

[0054] For further information, please refer to Figure 1 , Figure 2 As shown, the driving assembly 210 also includes a driving rod 212, which is connected to the driving element 211. The driving rod 212 extends along the width direction of the hull assembly 100, and includes a first driving part 2121 and a second driving part. The first driving part 2121 and the second driving part are located on both sides of the hull assembly 100 in the width direction; in the width direction of the hull assembly 100, the first driving part 2121 is transmission-connected to the transmission member 213 of the lifting unit 220 on the same side as the first driving part 2121; the second driving part is transmission-connected to the transmission member 213 of the lifting unit 220 on the same side as the second driving part. Through the above scheme, the driving rod 212 connected to the driving unit can be transmission-connected to different transmission members 213 respectively through the first driving part 2121 and the second driving part arranged along the width direction of the hull; because the driving rod 212 can transmit power along the width direction of the hull, those skilled in the art can more flexibly drive the position of the element 211, so as to cooperate with other structures in the oven.

[0055] For more information, see Figure 1 , Figure 2 As shown, according to some embodiments of the utility model, the driving element 211 is a hand wheel, the driving rod 212 connected to the driving element 211 extends in the width direction, the first driving part 2121 is located on the right side of the upper hull 110, and the second driving part is located on the left side of the upper hull 110. The first driving part 2121 and the second driving part are both bevel gears. The first driving part 2121 transmits power to the transmission member 213 located on the same side as the first driving part 2121 through meshing, and the second driving part transmits power to the transmission member 213 located on the same side as the second driving part through meshing. Without departing from the inventive concept of the utility model, those skilled in the art can set the driving element 211 on one side in the width direction of the hull, above the upper hull 110, or below the lower hull 120 according to actual conditions.

[0056] For further information, please refer to Figure 1 , Figure 2 , Figure 3 As shown, each lifting unit 220 also includes a support rod 221, which extends in the up and down directions, and an adjusting member 222 is connected to the support rod 221. The driving assembly 210 is used to drive each adjusting member 222 to rise and fall synchronously along the support rod 221; the lifting device 200 includes at least the same number of transmission members 213 as the lifting unit 220, and the transmission member 213 extends along the length direction of the hull assembly 100. The first driving part 2121 and the second driving part are connected to one end of the transmission member 213 through a bevel gear transmission, and the other end of the transmission member 213 is connected to the support rod 221 through a bevel gear transmission, and the adjusting member 222 is threadedly connected to the support rod 221. Through the above scheme, when the adjusting member 222 is threadedly connected to the support rod 221, since multiple adjusting members 222 are connected to the hull at the same time, the synchronous rotation of multiple support rods 221 can drive multiple adjusting members 222 to move up and down along the support rod 221; the driving element 211 can change the direction of transmitted power through the meshing relationship of the bevel gears between the driving rod 212 and the transmission member 213 so that the power is transmitted along the length direction of the hull, and change the direction of transmitted power again through the meshing relationship of the bevel gears between the transmission member 213 and the lifting unit 220 so that the power is transmitted along the height direction, so that the support rod 221 can rotate around itself, and the adjusting member 222 drives the hull to move up and down.

[0057] It should be understood that the above-mentioned embodiments have made detailed descriptions of the specific forms of adjusting the upper hull 110 by the lifting device 200 and the corresponding beneficial effects. Those skilled in the art can understand the specific forms of adjusting the lower hull 120 by the lifting device 200 and the corresponding beneficial effects through the above descriptions, which will not be repeated here.

[0058] Furthermore, the oven includes two lifting devices 200, and the multiple adjustment members 222 in one lifting device 200 are all connected to the upper hull 110; the multiple adjustment members 222 in the other lifting device 200 are all connected to the lower hull 120. Those skilled in the art can adjust the heights of the upper hull 110 and the lower hull 120 respectively through the two lifting devices 200, so as to adapt the oven to more production conditions.

[0059] In addition to the above solutions, please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, each lifting unit 220 includes two adjusting members 222, and the two adjusting members 222 are connected to the support rod 221; in the same lifting unit 220, the two adjusting members 222 are respectively connected to the upper hull 110 and the lower hull 120. Through the two adjusting members 222 of one lifting unit 220 respectively connected to the upper hull 110 and the lower hull 120, the oven can achieve height adjustment of the upper and lower hulls 120 through one lifting device 200.

[0060] The above-mentioned solution of using the rotating support rod 221 to adjust the height of the adjusting member 222 threadedly connected to the support rod 221 is described. Figure 1 , Figure 4 , Figure 5 As shown, according to some embodiments of the utility model, the upper hull 110 and the lower hull 120 are threadedly connected to the same support rod 221 through different adjusting members 222. When the support rod 221 rotates around itself, the two adjusting members 222 on the support rod 221 can rotate synchronously, thereby adjusting the height of the upper hull 110 and the lower hull 120 connected to the adjusting members 222.

[0061] Without departing from the inventive concept of the utility model, the two threads 2213 on the support rod 221 used to achieve threaded connection with the adjusting member 222 can be set to the same rotation direction, so that when the support rod 221 rotates, it can drive the two adjusting members 222 to move up and down synchronously, thereby driving the upper hull 110 and the lower hull 120 to move up and down synchronously.

[0062] As a preferred option, please refer to Figure 1 , Figure 5As shown, the support rod 221 includes an upper support section 2211 and a lower support section 2212 connected to each other, the thread 2213 provided on the upper support section 2211 is a positive thread, and the thread 2213 provided on the lower support section 2212 is a reverse thread; the adjusting member 222 connected to the upper hull 110 is threadedly connected to the upper support section 2211, and the adjusting member 222 connected to the lower hull 120 is threadedly connected to the lower support section 2212. Through the above scheme, when the support rod 221 rotates, it can drive the two adjusting members 222 to move toward or away from each other, thereby driving the upper hull 110 and the lower hull 120 to move toward or away from each other, and the pole piece channel 130 between the upper hull 110 and the lower hull 120 to open or contract.

[0063] For further information, please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, the two adjusting members 222 are both threadedly connected to the support rod 221, and the support rod 221 includes an upper support section 2211 and a lower support section 2212. The upper hull 110 is connected to the upper support section 2211 through one of the adjusting members 222, and the lower hull 120 is connected to the lower support section 2212 through the other adjusting member 222; the lifting device 200 has an independent adjustment state and a linkage state; in the independent adjustment state, the upper support section 2211 and the lower support section 2212 can rotate relative to each other; in the linkage state, the upper support section 2211 and the lower support section 2212 rotate synchronously. Through the above scheme, when the lifting device 200 is in a linkage state, the two adjusting members 222 on the support rod 221 can rotate synchronously, thereby simultaneously adjusting the height of the upper hull 110 and the lower hull 120 connected to the adjusting members 222; when the lifting device 200 is in an independent adjustment state, since the upper support section 2211 and the lower support section 2212 can rotate relative to each other, when the upper support section 2211 or the lower support section 2212 rotates around itself, there is a speed difference between the upper support section 2211 and the lower support section 2212, and the moving distances of the upper hull 110 and the lower hull 120 in the height direction are also different; technical personnel in this field can change the adjustment mode by switching the state of the lifting device 200, thereby adjusting the upper hull 110 and the lower hull 120 to an appropriate height.

[0064] For more information on how to switch the state of the lifting device 200, please refer to Figure 1 , Figure 2 , Figure 5 , Figure 6As shown, the lifting unit 220 also includes a locking member 2214, the upper support section 2211 and the lower support section 2212 are plugged in the up-down direction, and the locking member 2214 can be inserted into the upper support section 2211 and the lower support section 2212 in the horizontal direction, so that the upper support section 2211 and the lower support section 2212 can rotate synchronously in the linkage state, and the locking member 2214 can be separated from the upper support section 2211 and the lower support section 2212 in the horizontal direction, so that the upper support section 2211 and the lower support section 2212 can rotate relative to each other in the independent adjustment state. Through the above scheme, in the linkage state, the support rod 221 can transmit torque through the locking member 2214, so that the upper support section 2211 and the lower support section 2212 can rotate synchronously; in the independent adjustment state, the locking member 2214 is separated from the upper support section 2211 and the lower support section 2212, and the upper support section 2211 and the lower support section 2212 cannot transmit torque through the locking member 2214, so that they can rotate relative to each other. Compared with other specific methods of switching the state of the lifting device 200, the structure of the locking member 2214 that can be inserted and disengaged horizontally is simpler and more convenient for operators to operate.

[0065] For more information, see Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, according to some embodiments of the utility model, the driving assembly 210 can drive the upper support section 2211 to rotate. In the linkage state, the lower end portion of the upper support section 2211 extends into the groove of the lower support section 2212, and the locking member 2214 is horizontally inserted into the upper support section 2211 and the lower support section 2212; when the upper support section 2211 rotates, the upper support section 2211 can drive the lower support section 2212 to rotate synchronously through the locking member 2214, so that the support rod 221 can simultaneously adjust the height of the upper hull 110 and the lower hull 120 connected to the adjusting member 222. In the independent adjustment state, the locking member 2214 is no longer inserted into the upper support section 2211 and the lower support section 2212; when the upper support section 2211 rotates, the lower support section 2212 remains stationary, and the support rod 221 can only adjust the height of the upper hull 110 through the rotation of the upper support section 2211. During actual adjustment, the staff can first adjust the lower hull 120 to a suitable height in the linkage state, and then adjust the height of the upper hull 110 separately in the independent adjustment state. It should be noted that after the lifting device 200 of the above embodiment is switched from the linkage state to the independent adjustment state, since the lower end of the upper support section 2211 still partially extends into the groove of the lower support section 2212, when the height of the upper hull 110 is subsequently adjusted, the inner wall of the groove of the lower support section 2212 can limit the radial movement of the upper support section 2211, thereby making the adjustment process of the upper hull 110 smoother.

[0066] The embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the utility model. In addition, the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
