Description

Technical Field

[0001] This invention relates to the field of heating equipment technology, and more particularly to a vertical baking oven. Background Art

[0002] In modern industry, heating furnaces and baking ovens play important roles in process equipment. Among them, vertical furnaces have become one of the most widely used furnace types due to their advantages such as compact structure, uniform process airflow organization, and high space utilization.

[0003] However, traditional vertical furnaces face a common structural challenge in their design: to achieve the vertical movement of materials (such as wafers and circuit boards) within the furnace chamber, precision transmission mechanisms such as lead screws, chains, or gears are typically installed within the high-temperature cavity. This layout directly results in the transmission mechanisms operating under the high-temperature environment of the furnace for extended periods. On one hand, the extremely high ambient temperature significantly accelerates the aging, failure, and damage of critical components of the transmission mechanism (such as chains), leading to frequent equipment maintenance, increased downtime, and high maintenance costs, severely impacting equipment lifespan and production efficiency. On the other hand, these high-temperature and difficult-to-maintain transmission mechanisms inevitably generate contaminants such as metal friction dust or lubricant volatiles (containing carbon) during continuous operation. These contaminants easily disperse and deposit inside the furnace, especially under high-temperature and active conditions, severely degrading the cleanliness of the furnace's process environment. This not only causes fatal contamination of the surfaces of sensitive materials being processed, affecting product yield, but also contaminates internal furnace components (such as heating elements, thermocouples, and quartz components). This problem is particularly prominent in precision manufacturing processes with high cleanliness requirements.

[0004] Therefore, there is an urgent need for a vertical baking oven to solve the above-mentioned technical problems. Summary of the Invention

[0027] The accordion curtain has one end fixed to the furnace body and the other end connected to the end of the second vertical plate.

[0034] The vertical baking oven provided by this invention forms a power cavity between the mounting base plate and the oven body, and arranges the power mechanism in the power cavity, which is independent of the oven body. On the one hand, the temperature of the power cavity is significantly lower than that of the baking cavity, avoiding lubrication failure, material performance degradation, and rapid wear of the power mechanism caused by high temperature, thus significantly improving the reliability and service life of the power mechanism. On the other hand, the avoidance holes set in the bottom wall of the oven body are only used to avoid the passage of the fork mechanism. Most of the wear dust or lubricant volatiles generated by the operation of the power mechanism are isolated outside the baking cavity, which can effectively prevent contaminants from entering the baking cavity above, thereby ensuring that the baking cavity maintains a high degree of cleanliness, avoiding contamination of the workpiece surface and the components inside the oven, and improving product quality.

[0054] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0055] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0057] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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.

[0058] Existing vertical baking equipment typically uses a chain drive mechanism to move a carrier plate up and down layer by layer. Each chain link carries one carrier plate; when a link moves upward, it lifts the carrier plate a certain distance, and when a link moves downward, it lowers the carrier plate a certain distance. During operation, due to the meshing friction of the chain drive mechanism and the lubrication of the chain bearings, dust and grease accumulate inside the cavity, affecting overall cleanliness and reducing overall product performance. Furthermore, under the combined effects of high temperature and heavy load, the chain's positioning accuracy and structural stability are difficult to maintain, resulting in a short service life.

[0059] To solve the above technical problems, please refer to Figures 1-11This embodiment provides a vertical baking oven, which can be used to bake workpieces for curing processes or heating tests. Specifically, the vertical baking oven provided in this embodiment is applied to the drying process of circuit boards, curing conformal adhesive through high-temperature baking. The vertical baking oven includes a furnace body 20 and a board storage device. The furnace body 20 contains a baking cavity 200. The board storage device includes two sets of board storage units arranged opposite each other along a horizontal first direction (i.e., the X direction in the figure). Each board storage unit includes a power mechanism 30 and a fork mechanism 40. The fork mechanism 40 is located in the baking cavity 200. The two sets of fork mechanisms 40 are used to jointly support the workpiece. The fork mechanism 40 is connected to the power mechanism 30, which can drive the fork mechanism 40 to rise and fall and move along the first direction.

[0060] For further details, please refer to Figures 1-3 The vertical baking oven also includes a mounting base plate 10, and a furnace body 20 is spaced above the mounting base plate 10. A power cavity 100 is formed between the mounting base plate 10 and the furnace body 20. A power mechanism 30 is installed in the power cavity 100. The bottom wall of the furnace body 20 is provided with a clearance hole 21. A fork mechanism 40 passes through the clearance hole 21 into the power cavity 100 and is connected to the output end of the power mechanism 30.

[0061] Specifically, the vertical baking oven provided in this embodiment forms a power cavity 100 between the mounting base plate 10 and the oven body 20, and the power mechanism 30 is arranged in the power cavity 100, which is independent of the oven body 20. On the one hand, the temperature of the power cavity 100 is significantly lower than that of the baking cavity 200, avoiding lubrication failure, material performance degradation and rapid wear of the power mechanism 30 caused by high temperature, and significantly improving the reliability and service life of the power mechanism 30. On the other hand, the avoidance hole 21 provided on the bottom wall of the oven body 20 is only used to avoid the material fork mechanism 40 from passing through. Most of the wear dust or lubricant volatiles generated by the operation of the power mechanism 30 are isolated outside the baking cavity 200, which can effectively prevent contaminants from entering the baking cavity 200 above, thereby ensuring that the baking cavity 200 maintains a high cleanliness, avoiding contamination of the workpiece surface and the components inside the oven, and improving product quality.

[0062] For example, please refer to Figures 7-10 The fork mechanism 40 includes a lifting fork assembly 41 and a translating fork assembly 42. The power mechanism 30 includes a lifting power assembly 31 and a translating power assembly. The output end of the lifting power assembly 31 is connected to the lifting fork assembly 41 and can drive the lifting power assembly 31 to move vertically. The translating power assembly has two different output ends to be connected to the lifting fork assembly 41 and the translating fork assembly 42 respectively, thereby driving the lifting fork assembly 41 and the translating fork assembly 42 to move horizontally along the first direction respectively.

[0063] Specifically, the two sets of fork mechanisms 40 arranged opposite each other form a space for accommodating workpieces. In the first direction, both the lifting fork assembly 41 and the translating fork assembly 42 have a first station for supporting the workpiece and a second station for detaching from the workpiece. The two sets of storage units arranged opposite each other always operate synchronously, including synchronous lifting and synchronous translating towards or away from each other. When the lifting fork assembly 41 is in the first station and the translating fork assembly 42 is in the second station, the two sets of lifting fork assemblies 41 support the two side edges of the workpiece respectively, and the lifting fork assembly 41 can drive the workpiece to rise and fall. When the lifting fork assembly 41 is in the second station and the translating fork assembly 42 is in the first station, the two sets of translating fork assemblies 42 support the two side edges of the workpiece respectively, and the lifting fork assembly 41 can rise and fall independently. When both the lifting fork assembly 41 and the translating fork assembly 42 are in the first station, the lifting fork assembly 41 and the translating fork assembly 42 jointly support the side edges of the workpiece. By switching the states of the lifting fork assembly 41 and the translating fork assembly 42, it is possible to alternately carry workpieces and lift or lower workpieces layer by layer.

[0064] For details regarding the structure of the lifting fork assembly 41, please refer to [link / reference]. Figure 7-Figure 9 The lifting fork assembly 41 includes a lifting connecting frame 411, a lifting fork 412, and a top plate 413. The upper end of the lifting connecting frame 411 is provided with multiple lifting guide rods 315 arranged vertically. The top plate 413 is fixed to the upper end of the multiple lifting guide rods 315. The lifting fork 412 is slidably disposed on the multiple lifting guide rods 315 through multiple lifting linear bearings 316, thereby sliding relative to the lifting connecting frame 411 in a vertical direction. The lifting connecting frame 411 passes through the clearance hole 21. The lifting power assembly 31 is installed on the lifting connecting frame 411. The output end of the lifting power assembly 31 is connected to the lifting fork 412 and can drive the lifting fork 412 to rise and fall.

[0065] Please refer to Figure 9 The lifting connecting frame 411 includes multiple first vertical plates 4111, which are arranged along a first direction, and the multiple first vertical plates 4111 are correspondingly inserted into multiple clearance holes 21 along the vertical direction. The arrangement direction of the first vertical plates 4111 is consistent with the horizontal movement of the first vertical plates 4111. The clearance holes 21 are also set as strip-shaped holes along the first direction. The length of the clearance holes 21 is greater than the width of the first vertical plates 4111 in the first direction, so as to allow the first vertical plates 4111 to move within them along the first direction, while controlling the gap between the first vertical plates 4111 and the clearance holes 21 to reduce heat loss and external dust entering the baking cavity 200.

[0066] For details regarding the specific structure of the lifting power component 31, please refer to [link / reference needed]. Figure 9The lifting power assembly 31 includes a rotary motor 311, a reducer 312, a ball screw 313, and a screw nut 314. The reducer 312 is installed at the bottom of the lifting connecting frame 411. The output shaft of the rotary motor 311 is connected to the lower input end of the reducer 312, and the upper output end of the reducer 312 is connected to the ball screw 313. The reducer 312 is arranged vertically. The screw nut 314 is threadedly connected to the ball screw 313. The lifting fork 412 is fixedly connected to the screw nut 314. The rotary motor 311 can drive the ball screw 313 to rotate around the vertical axis, so as to drive the lifting fork 412 to rise and fall along multiple lifting guide rods 315.

[0067] For example, please continue to refer to Figure 9 The length of the ball screw 313 is less than the length of the lifting guide rod 315. The ball screw 313 is spaced apart from the top plate 413 in the height direction to reduce the length of the ball screw 313 extending into the baking cavity 200 and reduce the impact of the lubricating grease on the ball screw 313 on the baking cavity 200. Optionally, the length of the ball screw 313 is less than 0.2 times the length of the lifting guide rod 315.

[0068] For example, the rotary motor 311 is a servo motor, which can precisely control the lifting height of the lifting fork 412.

[0069] For details regarding the structure of the lifting fork 412, please refer to [link / reference]. Figure 7 and Figure 9 The lifting fork 412 includes multiple first fork plates 4121 and first back plates 4123 spaced apart along a first direction. A clearance gap 4122 is formed between adjacent first fork plates 4121 to allow horizontal movement of the translation fork assembly 42 along the first direction. Multiple first support portions 41211 are spaced apart along a vertical direction and are used to support the workpiece. Multiple first back plates 4123 are spaced apart on the side of the multiple first fork plates 4121 opposite to the workpiece. A roller screw and lifting guide rod 315 are located in the gap between the first back plate 4123 and the first fork plates 4121. Specifically, the first support portion 41211 is configured as a boss structure, and a first support groove is formed between two adjacent first support portions 41211 in the height direction. The edge of the workpiece is inserted into the first support groove. The lower first support portion 41211 supports the workpiece, and the upper first support portion 41211 can limit the degree of freedom of the workpiece in the height direction, thereby improving the stability of storage and lifting.

[0070] For details regarding the composition of the translation fork assembly 42, please refer to [link / reference]. Figure 7 , Figure 8 and Figure 10The translation fork assembly 42 includes a translation connecting frame 421 and a translation fork 422. The translation connecting frame 421 is fixedly connected to the bottom of the translation fork 422 and passes through the clearance hole 21. Specifically, the mounting base plate 10 is provided with a mounting seat 11, and the mounting seat 11 is provided with a translation slide rail 12 arranged along a first direction. The translation connecting frame 421 includes multiple second vertical plates 4211, which are arranged along the first direction and are vertically correspondingly passed through multiple clearance holes 21. The setting direction of the second vertical plates 4211 is consistent with the horizontal movement of the second vertical plates 4211. The length of the clearance hole 21 is greater than the width of the second vertical plate 4211 in the first direction to allow the second vertical plate 4211 to move within it along the first direction, while controlling the gap between the first vertical plate 4211 and the clearance hole 21 to reduce heat loss and external dust entering the baking cavity 200.

[0071] Understandably, the lengths of the multiple clearance holes 21 on the bottom wall of the furnace body 20 along the first direction are not the same, in order to accommodate the different sizes of the plate-like structures passing through them and the different distances of horizontal movement.

[0072] Regarding the structure of the translation fork 422, please refer to [link / reference]. Figure 7 , Figure 8 and Figure 10 The translation fork 422 includes multiple second fork plates 4221 spaced apart along a first direction, a lower connecting plate 4222, an upper connecting plate 4223, and a second back plate 4224. The translation connecting frame 421 is located on the side of the lifting connecting frame 411 away from the workpiece. The bottom end of the second fork plate 4221 is connected to the translation connecting frame 421 through the lower connecting plate 4222. The upper connecting plate 4223 is connected to the upper end of the second fork plate 4221. The second back plate 4224 connects both the upper connecting plate 4223 and the lower connecting plate 4222. The multiple second fork plates 4221 protrude relative to the translation connecting frame 421 along the first direction toward the lifting fork assembly 41 and are correspondingly inserted into multiple clearance gaps 4122. The second fork plate 4221 is provided with multiple second support portions 42211 spaced apart along the vertical direction. The second support portions 42211 are used to support the workpiece. Specifically, the second support portion 42211 is configured as a boss structure, and a second support groove is formed between two adjacent second support portions 42211 in the height direction. The edge of the workpiece is inserted into the second support groove. The lower second support portion 42211 supports the workpiece, and the upper second support portion 42211 can limit the workpiece's degree of freedom in the height direction, improving the stability of storage and lifting. It can be understood that the height of the second support portion 42211 is equal to the height of the first support portion 41211, and the interval between two adjacent second support portions 42211 is equal to the interval between two adjacent first support portions 41211, that is, the height of the second support groove is also equal to the height of the first support groove.

[0073] For information on the composition of the translational force components, please refer to [link / reference]. Figure 5 and Figure 8 The translational motion assembly includes a first linear drive 32 and a second linear drive 33, both of which are fixedly mounted on the mounting base 11. The output end of the first linear drive 32 is connected to the translation connecting frame 421 and can drive the translation fork 422 to slide along the translation slide rail 12. The lifting connecting frame 411 is slidably disposed on the translation slide rail 12. The output end of the second linear drive 33 is connected to the lifting connecting frame 411 and can drive the lifting fork 412 to slide along the translation slide rail 12. Specifically, both the first linear drive unit 32 and the second linear drive unit 33 are mounted below the mounting base 11 via a fixing plate. The output end of the first linear drive unit 32 is connected to the translation connecting frame 421 via the first drive plate 321. The mounting base 11 is provided with a drive clearance hole 13 for the first drive plate 321 to pass through. The output end of the second linear drive unit 33 is connected to the lifting connecting frame 411 via the second drive plate 331. The mounting base 11 is provided with a drive clearance groove 14 for avoiding the second drive plate 331 and the lifting power assembly 31. Under the drive of the first linear drive unit 32 and / or the second linear drive unit 33, the lifting fork 412 and the translation fork 422 move between the first station and the second station. The second fork plate 4221 can extend out of the clearance gap 4122. At the same time, at least one of the lifting fork 412 and the translation fork 422 is in the first station to support the workpiece.

[0074] In this embodiment, in the initial state, the lifting fork 412 is in the first working position, the translating fork 422 is in the second working position, and the lifting fork 412 alone carries the workpiece.

[0075] To lift the workpiece layer by layer, the storage unit has an upward cycle path: the lifting fork 412 and the workpiece rise together to a preset height, the translating fork 422 moves to the first station to receive the workpiece, the lifting fork 412 moves to the second station, the lifting fork 412 descends to a preset height, and the lifting fork 412 moves to the first station to receive the next layer of workpiece. Driven by the lifting power assembly 31, the first linear drive 32, and the second linear drive 33, the upward cycle path is executed cyclically, thus realizing the function of lifting the workpiece layer by layer.

[0076] Similarly, to lower workpieces layer by layer, the storage unit has a descent cycle path: the lifting fork 412 and the workpiece descend together to a preset height, the translating fork 422 moves to the first station to receive the workpiece, the lifting fork 412 moves to the second station, the lifting fork 412 rises to a preset height, and the lifting fork 412 moves to the first station to receive the upper-layer workpiece. Driven by the lifting power assembly 31, the first linear drive 32, and the second linear drive 33, the descent cycle path is executed cyclically, thus realizing the function of lowering workpieces layer by layer. It can be understood that the preset height is the height difference between two adjacent first support slots.

[0077] For example, both the first linear drive unit 32 and the second linear drive unit 33 are linear cylinders, which have simple structure and control and high cleanliness.

[0078] For example, please refer to Figure 2 , Figure 3 , Figure 4 and Figure 6 The vertical baking oven also includes an isolation component 50, which is connected to the translational connecting frame 421. The isolation component 50 is used to seal the gap between the translational connecting frame 421 and the wall of the clearance hole 21.

[0079] Specifically, please refer to Figure 4 and Figure 11 The isolation assembly 50 includes an isolation plate 51 and a bellows curtain 52. The isolation plate 51 includes a first part 511 and a second part 512. The first part 511 is arranged vertically and connected to the side wall of the second vertical plate 4211. The second part 512 is arranged horizontally and covers the gap between the clearance hole 21 and the side wall of the second vertical plate 4211. One end of the bellows curtain 52 is fixed to the furnace body 20 by a first connecting plate 521, and the other end is connected to the end of the second vertical plate 4211 by a second connecting plate 522. When the translation connecting frame 421 moves along the first direction, the bellows curtain 52 extends and retracts accordingly and covers the gap between the clearance hole 21 and the end of the second vertical plate 4211. By combining a rigid shielding structure and a flexible follow-up shielding structure, the dustproof and heat insulation effect is improved.

[0080] For example, please refer to Figure 11 The isolation assembly 50 includes two isolation plates 51, which are respectively connected to the two side walls of the second vertical plate 4211 in the horizontal second direction (i.e., the Y direction in the figure) to simultaneously shield the gap between the two side walls of the second vertical plate 4211 and the hole wall of the clearance hole 21, thereby further improving the dustproof and heat insulation effect. The first direction is perpendicular to the second direction.

[0081] In some embodiments, a follow-up, flexible isolation structure, such as a corrugated pipe, may be provided between the lifting connecting frame 411 and the hole wall of the clearance hole 21 to further improve the dustproof and heat insulation effect.

[0082] For example, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 The storage plate device also includes a spacing adjustment mechanism 60, at least a portion of which is mounted on the power cavity 100. The output end of the spacing adjustment mechanism 60 is connected to at least one storage plate unit. The spacing adjustment mechanism 60 can drive the corresponding storage plate unit to move along a first direction to adjust the spacing between two sets of storage plate units, thereby adapting to workpieces of different widths and improving versatility.

[0083] Please refer to Figure 5 The spacing adjustment mechanism 60 includes a spacing adjustment motor 61, a transmission belt assembly 62, a transmission screw assembly 63, and an adjustment guide assembly 64. The spacing adjustment motor 61 is mounted on the bottom of the mounting base plate 10. The transmission belt assembly 62 passes vertically through the mounting base plate 10. The input end of the transmission belt assembly 62 located below the mounting base plate 10 is connected to the output shaft of the spacing adjustment motor 61. The output end of the transmission belt assembly 62 located above the mounting base plate 10 is connected to the lead screw of the transmission screw assembly 63. The nut of the lead screw of the transmission screw assembly 63 is fixedly connected to the mounting seat 11 corresponding to the storage unit. The mounting seat 11 is slidably connected to the mounting base plate 10 through the adjustment guide assembly 64 arranged along the first direction. The adjustment guide assembly 64 includes a guide rod extending along the first direction and several guide blocks slidably disposed thereon. The multiple guide blocks simultaneously connect to and support the mounting seat 11. When the spacing adjustment motor 61 is activated, it drives the entire storage unit to move along the first direction via the transmission belt assembly 62 and the transmission screw assembly 63 to adjust the spacing between the two sets of storage units.

[0084] For example, please refer to Figure 3 and Figure 6 The vertical baking oven includes two sets of plate storage devices. The vertical baking oven has a feeding area 210 and a discharging area 220 distributed along a second horizontal direction. One set of plate storage devices is located in the feeding area 210, and the other set of plate storage devices is located in the discharging area 220. The two sets of plate storage devices convey the workpieces in opposite directions in the vertical direction. Correspondingly, along the second direction, the mounting base plate 10 and the mounting seat 11 are each provided with two mounting positions for adapting the plate storage devices. The furnace body 20 is provided with flow holes 22 at both ends in the second direction for workpieces to flow in and out. The furnace body 20 is provided with furnace doors 23 at both ends in the first direction for workers to open and inspect the plate storage devices.

[0085] In this embodiment, the heights of the two flow holes 22 correspond to the lowest position of the workpiece carried by the fork mechanism 40. During operation, the workpiece is placed into the flow hole 22 near the loading area 210 by the robotic arm. In the loading area 210, the two storage units of the storage device execute an upward cycle path. In the loading area 210, the translation fork 422 and / or the lifting fork 412 receive the workpiece. Every certain time interval, the translation fork 422 retracts to the second station, disengages from the workpiece, and enters the initial state. The lifting fork 412 drives the workpiece to rise one layer. The translation fork 422 extends to the first station to receive the workpiece. At this time, the lifting fork 412 retracts to the second station and lowers one layer. The lifting fork 412 extends to the first station again to receive another workpiece below. This cycle repeats, so that the workpiece in the loading area 210 rises one layer every certain time interval. In the unloading area 220, the two storage units of the storage device execute a descent cycle path. In the unloading area 220, at specific time intervals, the translation fork 422 retracts to the second station, detaches from the workpiece, and enters the initial state. The lifting fork 412 drives the workpiece to descend one layer. The translation fork 422 extends to the first station to receive the workpiece. At this time, the lifting fork 412 retracts to the second station and rises one layer. The lifting fork 412 extends to the first station again to receive another workpiece above. This cycle repeats, so that the workpiece in the unloading area 220 descends one layer at specific time intervals. When it finally descends to the bottom layer, the workpiece is taken out from the flow hole 22 on the side near the unloading area 220 by the robotic arm.

[0086] In some embodiments, a pushing device is provided on the top plate 413. The pushing device can be a linear cylinder or a linear slide. The pushing device is used to push the workpiece at the top of the loading area 210 to the top of the unloading area 220.

Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
