Description

Technical Field

[0001] This invention relates to the field of ovens, and more specifically, to an oven liner height adjustment device and method. Background Technology

[0002] After the electrode surface is coated with electrode paste, it needs to be heated and dried in a coating oven to solidify the coating layer. When the end of the electrode foil passes through the oven for the first time, the inner liner of the oven usually needs to be raised to complete the threading process. This is typically achieved by setting screw and nut mechanisms at multiple positions within the inner liner of the oven. By rotating the nuts, the screws fitted inside the nuts move vertically, thus raising and lowering the inner liner of the oven. This setup requires rotating the nuts at multiple positions simultaneously and at the same speed. However, in actual operation, it is difficult to achieve simultaneous activation and simultaneous displacement of all screw and nut mechanisms. This results in the screw and nut mechanisms being at different heights at the same time during adjustment, causing the inner liner of the oven to shift and tilt, leading to wear between the screws and nuts.

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0037] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0038] In the description of this invention, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed, they are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0039] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0040] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0041] The following is combined Figures 1 to 7 The oven inner liner height adjustment device 10 provided in this embodiment will be described in detail.

[0042] Please refer to Figure 1 as well as Figure 2 An embodiment of the present invention provides a height adjustment device 10 for an oven liner, including a first drive mechanism 100, an oven liner 200, and multiple ropes 300; the multiple ropes 300 are distributed at intervals along the outer periphery of the oven liner 200; each rope 300 has a drive end and a connection end at both ends, the drive end of each rope 300 is connected to the first drive mechanism 100, and the connection end of each rope 300 is connected to the oven liner 200; the first drive mechanism 100 is used to drive the multiple ropes 300 to move synchronously, so as to drive the oven liner 200 to rise or fall.

[0043] After the electrode slurry is applied to the surface of the electrode 11, it needs to be heated and dried in a coating oven to solidify the coating layer on the surface of the electrode 11. The oven inner liner height adjustment device 10 is used to adjust the height of the inner liner within the coating oven. A first drive mechanism 100 simultaneously drives multiple ropes 300, whose connecting ends are respectively attached to the outer periphery of the oven inner liner 200, at the same speed, to achieve a smooth lifting of the oven inner liner 200. Since all multiple ropes 300 are driven by the first drive mechanism 100, and the multiple ropes 300 move up and down at the same speed, pulling all parts of the oven inner liner 200 up or down at the same speed, it is less likely to cause asynchronous problems between different parts of the oven inner liner 200, ensuring a smooth rise of the oven inner liner 200. This also reduces the likelihood of skewed wear on the multiple ropes 300, resulting in a long service life.

[0044] Reference Figure 1 , Figure 2 as well as Figure 3 In this embodiment, the first driving mechanism 100 is disposed above the inner liner 200 of the oven; the first driving mechanism 100 includes a fixed plate 110 and a first driving member 120; the fixed plate 110 is slidably disposed along a first preset direction; the driving ends of multiple ropes 300 are all connected to the fixed plate 110; the first driving member 120 is connected to the fixed plate 110, and the first driving member 120 is used to push the fixed plate 110 to slide back and forth along the first preset direction, and the fixed plate 110 is used to drive the multiple ropes 300 to move synchronously during the sliding process.

[0045] Reference Figure 1 as well as Figure 3The first preset direction is along the width direction of the inner liner 200 of the oven, that is, the direction from the front end to the rear end of the inner liner 200. The first drive mechanism 100 also includes a first slide rail 130, which is set along the first preset direction. The fixing plate 110 is slidably set on the first slide rail 130. The first drive mechanism 100 is connected to the fixing plate 110. The first drive mechanism 100 drives the fixing plate 110 to reciprocate along the first slide rail 130, pulling multiple ropes 300 to move up and down synchronously. The inner liner height adjustment device 10 also includes a positioning sensor 12 set on one side of the first slide rail 130, used to sense whether the fixing plate 110 has moved into position.

[0046] The fixing plate 110 provides connection positions for the drive ends of multiple ropes 300. The drive ends of the multiple ropes 300 must be connected to the fixing plate 110 in a balanced state to ensure that the fixing plate 110 is subjected to balanced forces and does not tilt during movement. For example, in this embodiment, there are four ropes 300, with two ropes 300 connected to one end of the fixing plate 110 and the remaining two ropes 300 connected to the other end of the fixing plate 110. The drive ends of the four ropes 300 are symmetrically arranged relative to the center of the fixing plate 110.

[0047] Reference Figure 1 , Figure 2 as well as Figure 3 In this embodiment, there are four ropes 300; the driving ends of the four ropes 300 are all connected to the fixing plate 110, and the connecting ends of the four ropes 300 are respectively connected to the four outer corners of the oven inner liner 200.

[0048] It should be noted that the term "external angle" in this article refers to any area within a preset distance radiating from the corner of the oven liner 200 in the width or length direction of the oven liner 200.

[0049] The driving ends of the four ropes 300 are symmetrically arranged relative to the center of the fixed plate 110. The inner liner of the oven 200 has four outer corners, and the connecting ends of the four ropes 300 are respectively connected to the four outer corners to ensure that the tension of the ropes 300 on the inner liner of the oven 200 is balanced.

[0050] Specifically, with Figure 1 as well as Figure 2The relative positions of the ropes are described below. Two ropes 300 are symmetrically arranged at the front end of the oven inner liner 200, and the remaining two ropes 300 are arranged at the rear end of the oven inner liner 200. Specifically, the four ropes 300 are the first rope 301, the second rope 302, the third rope 303, and the fourth rope 304. The driving ends of the first rope 301 and the second rope 302 are connected to the right end of the fixed plate 110, and the driving ends of the third rope 303 and the fourth rope 304 are connected to the left end of the fixed plate 110.

[0051] In this embodiment, the oven inner liner height adjustment device 10 also includes four adjustment wheels 400; the four adjustment wheels 400 are respectively arranged between the four outer corners of the oven inner liner 200 and the fixing plate 110, and each rope 300 is wound around the adjustment wheel 400 and connected to the fixing plate 110.

[0052] In another embodiment, the positions of the four adjusting wheels 400 are adjustable. The adjusting wheels 400 are used to adjust the length of the corresponding rope 300 between the adjusting wheel 400 and the outer corner of the oven inner liner 200 during the movement, so as to adjust the height of the corresponding outer corner position of the oven inner liner 200.

[0053] Specifically, the four adjusting wheels 400 are arranged in a square. Each rope 300 passes around the adjusting wheel 400 and connects to the fixed plate 110. When the position of the adjusting wheel 400 moves, the rope 300 wrapped around the adjusting wheel 400 moves a certain distance relative to the adjusting wheel 400, thereby causing the corresponding position of the oven inner liner 200 to rise or fall. Adjusting wheels 400 are provided at each of the four outer corners of the oven inner liner 200. By adjusting the position of each adjusting wheel 400, the rise or fall of each outer corner of the oven inner liner 200 can be adjusted individually, thereby achieving localized adjustment of the heating temperature of the electrode 11.

[0054] by Figure 1 For example, assuming the oven is initially suspended horizontally, the adjusting wheel 400 corresponding to the second rope 302 slides along direction a. At this time, the second rope 302 will move along direction b. If the adjusting wheel 400 around which the other ropes 300 pass is stationary, then a corner of the oven liner 200 connected to the end of the second rope 302 will drop down, shortening the distance between this position and the lower electrode 11, thereby increasing the local heating temperature of the electrode 11.

[0055] Reference Figure 3 In this embodiment, the oven inner liner height adjustment device 10 further includes four second drive mechanisms; the four second drive mechanisms are respectively connected to four adjustment wheels 400; each second drive mechanism drives the adjustment wheel 400 to slide back and forth along a second preset direction, the second preset direction being parallel to the first preset direction.

[0056] Each adjusting wheel 400 is provided with a corresponding second driving mechanism, which drives the corresponding adjusting wheel 400 to move along a second preset direction. The second preset direction is also along the width direction of the oven inner liner 200. The oven inner liner height adjustment device 10 also includes a second slide rail 510, which is set along the second preset direction. The adjusting wheel 400 is slidably mounted on the second slide rail 510, and the second driving mechanism drives the adjusting wheel 400 to reciprocate along the second slide rail 510.

[0057] Reference Figure 7 The specific closed-loop temperature control method is as follows: the heating area below the inner liner 200 of the oven liner 11 is divided into a first detection area 001, a second detection area 002, a third detection area 003, and a fourth detection area 004. The temperature in the detection area is detected and identified by the detection unit. When the actual temperature of the detection area is lower than the corresponding preset temperature, the corresponding adjustment wheel 400 is driven to lower the inner liner 200 of the oven liner 200 in that detection area, thereby increasing the heating temperature of that area. Conversely, when the actual temperature of the detection area is higher than the corresponding preset temperature, the inner liner 200 of the oven liner 200 in that detection area is raised to lower the heating temperature of that area.

[0058] Reference Figure 2 as well as Figure 4 In this embodiment, the oven inner liner height adjustment device 10 also includes two balance wheels 600; the two balance wheels 600 are symmetrically arranged relative to the fixed plate 110, and each balance wheel 600 is located between two adjustment wheels 400. Two ropes 300 extending from the two adjustment wheels 400 cross and wrap around the balance wheel 600 in opposite circumferential directions, and then connect to the fixed plate 110.

[0059] Two balance wheels 600 are disposed on both sides of the first drive mechanism 100. Two adjustment wheels 400 are disposed on both sides of the first drive mechanism 100. The balance wheels 600 are disposed between the two adjustment wheels 400. The first rope 301 and the second rope 302 are respectively wrapped around the corresponding adjustment wheels 400 and then cross-wound around the balance wheel 600. The first rope 301 is wrapped around the balance wheel 600 in the forward direction, and the second rope 302 is wrapped around the balance wheel 600 in the reverse direction to achieve symmetry with respect to the balance wheel 600. Similarly, the third rope 303 and the fourth rope 304 are respectively wrapped around the corresponding adjustment wheels 400 and then cross-wound around the balance wheel 600. The third rope 303 is wrapped around the balance wheel 600 in the forward direction, and the fourth rope 304 is wrapped around the balance wheel 600 in the reverse direction to achieve symmetry with respect to the balance wheel 600.

[0060] The first rope 301 and the second rope 302 are symmetrical with respect to their corresponding balance wheels 600, and the third rope 303 and the fourth rope 304 are symmetrical with respect to their corresponding balance wheels 600. The two balance wheels 600 are symmetrically arranged with respect to the first drive mechanism 100. The forces on the two balance wheels 600 are opposite in direction and partially cancel each other out, preventing the first drive mechanism 100 from bending and deforming to one side due to the force being concentrated on one side. This further improves the lifting stability of the oven inner liner 200 and extends the service life of the first drive mechanism 100.

[0061] Reference Figure 1 as well as Figure 3 In this embodiment, the oven inner liner height adjustment device 10 also includes two guide wheels 700; the two guide wheels 700 are symmetrically arranged relative to the fixed plate 110, and the guide wheels 700 are located between the fixed plate 110 and the balance wheel 600. Two ropes 300 extending from the balance wheel 600 pass around the guide wheels 700 in the same direction and are connected to the fixed plate 110.

[0062] Specifically, the guide wheel 700 and the balance wheel 600 are spaced apart along a third preset direction, which is perpendicular to the first preset direction.

[0063] The guide wheel 700 is used to guide the rope 300 out in the same direction for connection to the fixing plate 110. Figure 3 The relative positions of the three ropes are described below. The third rope 303 and the fourth rope 304 on the left side pass through the lead-out wheel 800 from left to right and are connected to the left end of the fixing plate 110. The first rope 301 and the second rope 302 on the right side pass through the lead-out wheel 800 from right to left and are connected to the right end of the fixing plate 110.

[0064] Reference Figure 1 as well as Figure 2 In this embodiment, the oven inner liner height adjustment device 10 also includes four lead-out wheels 800; the four lead-out wheels 800 are respectively arranged between the adjustment wheel 400 and the outer corner of the oven inner liner 200, and the rope 300 led out from the adjustment wheel 400 passes around the lead-out wheels 800 and is connected to the oven inner liner 200.

[0065] Four pulleys 800 are arranged in a square. Each rope 300 is led out from the pulley 800 and connected to the inner liner 200 of the oven. The pulleys 800 are led out vertically to facilitate the connection of the rope 300 with the inner liner 200 of the oven in a vertical direction, so as to pull the inner liner 200 of the oven in a vertical direction.

[0066] Reference Figure 2 as well as Figure 5In this embodiment, the oven inner liner height adjustment device 10 further includes four sets of limiting components 900; the four sets of limiting components 900 are respectively disposed at the four outer corners of the oven inner liner 200; each limiting component 900 includes a connecting rod 910, a first limiting member 920, a second limiting member 930, and a third driving mechanism 940; the connecting rod 910 is connected to the outer corner of the oven inner liner 200, and the first limiting member 920 is fixed to the connecting rod 910; the third driving mechanism 940 is connected to the second limiting member 930, and the third driving mechanism 940 is used to drive the second limiting member 930 to approach or move away from the first limiting member 920, and the second limiting member 930 is used to abut against the bottom of the first limiting member 920 during the process of approaching the first limiting member 920, so as to prevent the first limiting member 920 from moving downward.

[0067] The top of the connecting rod 910 is provided with a first limiting member 920. After the oven liner 200 is raised and held, the third drive mechanism 940 drives the second limiting member 930 to move toward the connecting rod 910, so that the second limiting member 930 moves below the first limiting member 920. In the event that the rope 300 breaks or the first drive mechanism 100 is damaged, the first limiting member 920 can abut against the top of the second limiting member 930 to prevent the oven liner 200 from falling and being damaged, or from injuring the personnel who are putting on the harness below the oven liner 200.

[0068] Specifically, the second limiting member 930 is a U-shaped member. As the second limiting member 930 approaches the first limiting member 920, it gets stuck at the bottom of the first limiting member 920. The second limiting member 930 abuts against the bottom of the first limiting member 920 to prevent the first limiting member 920 and the connecting rod 910 from continuing to move downward, thereby limiting the extreme position of the oven inner liner 200's descent.

[0069] Reference Figure 6 In this embodiment, each connecting rod 910 includes a first section rod 911, a second section rod 912, and a universal coupling 913; the first section rod 911 and the second section rod 912 are connected by the universal coupling 913; a first limiting member 920 is provided at the end of the first section rod 911 away from the universal coupling 913, and the end of the second section rod 912 away from the first section rod 911 is connected to the inner liner 200 of the oven.

[0070] The connecting rod 910 is mounted on the oven. As the inner liner 200 of the oven moves up and down, the connecting rod 910 moves synchronously. When the inner liner 200 rises or falls at a certain outer corner, the corresponding connecting rod 910 also moves up and down synchronously. To avoid interference from the oven, the connecting rod 910 is configured as a first section 911 and a second section 912 connected by a universal coupling 913. This allows the first section 911 and the second section 912 to tilt relative to each other, enabling the connecting rod 910 to move as much as possible with the oven's inner liner 200, without significant friction or interference due to tilting. The relative rotation of the first section 911 and the second section 912 allows for better adaptation to the oven as it moves up and down with the inner liner 200, reducing friction and interference.

[0071] The oven inner liner height adjustment device 10 provided in this embodiment has at least the following advantages:

[0072] The first drive mechanism 100 drives multiple ropes 300 to move synchronously. The multiple ropes 300 move at the same speed, so as to achieve a smooth lifting of the oven liner 200 and prevent the oven liner 200 from shifting or tilting.

[0073] The third drive mechanism 940 drives the adjustment wheel 400 to move, so that the connecting end of the corresponding rope 300 can rise or fall independently, thereby enabling one or more of the four corners of the oven liner 200 to independently descend or rise, and thus adjusting the local heating temperature of the electrode 11.

[0074] An embodiment of the present invention also provides a method for adjusting the height of an oven liner, used to control the oven liner height adjusting device 10. The method for adjusting the height of the oven liner includes:

[0075] Acquire the preset height signal that represents the preset height of the oven inner liner at 200°.

[0076] The first drive mechanism 100 is controlled according to the preset height signal until the inner liner 200 of the oven reaches the preset height.

[0077] The first drive mechanism 100 controls the time and speed at which the drive rope 300 moves up and down, according to the preset height that the inner liner 200 of the oven needs to be adjusted to, so that the inner liner 200 of the oven is adjusted to the preset height.

[0078] In this embodiment, the oven inner liner height adjustment device further includes four adjusting wheels 400 and four second drive mechanisms. The four adjusting wheels 400 are respectively disposed above the four outer corners of the oven inner liner 200. Each rope 300 is wound around an adjusting wheel 400, and the four second drive mechanisms are respectively connected to the four adjusting wheels 400. Each second drive mechanism drives the adjusting wheel 400 to slide back and forth along a second preset direction, which is parallel to the first preset direction. The oven inner liner height adjustment method further includes:

[0079] Acquire real-time signals representing the temperature of the four outer corners of the oven liner 200;

[0080] The second drive mechanism is controlled according to the real-time signal until the temperature of the four outer corners of the oven liner 200 reaches the preset temperature.

[0081] Reference Figure 7 The heating area below the inner liner 200 of the oven for electrode 11 is divided into a first detection area 001, a second detection area 002, a third detection area 003, and a fourth detection area 004. The temperature in the detection area is detected and identified by the detection unit. When the actual temperature of the detection area is lower than the corresponding preset temperature, the corresponding adjustment wheel 400 is driven to lower the inner liner 200 of the oven in that detection area, thereby increasing the heating temperature of that area. Conversely, when the actual temperature of the detection area is higher than the corresponding preset temperature, the inner liner 200 of the oven in that detection area is raised to lower the heating temperature of that area, thus achieving local heating temperature adjustment of electrode 11.
