Description

Technical Field

[0001] This utility model relates to the field of door components, and more specifically, to an opening and closing component and a baking device. Background Technology

[0002] The baking apparatus has multiple baking chambers, each with a corresponding door assembly and opening / closing assembly. The opening / closing assembly is used to open or close the baking chamber. The workpiece to be baked is placed inside the baking chamber. When the door assembly is opened, it is used to retrieve the workpiece; when the door assembly is closed, the baking chamber forms a relatively sealed space for baking the workpiece. With increasing mechanization and the expansion of factory production lines, more stringent requirements are placed on the automation performance of the opening / closing assembly and the floor space required for the baking apparatus.

[0003] CN219433633U proposes a vacuum chamber with an automatically switching built-in heating source, including a chamber frame with several mounting cavities, each containing a baking chamber. Several automatic switching devices are symmetrically arranged on the chamber frame. Each baking chamber has an opening, and each opening is equipped with a door assembly. The door assembly is controlled to open and close via the automatic switching devices. A sealing ring is provided on the surface of the baking chamber. When the door assembly is closed, the inner wall of the door assembly and the sealing ring are tightly fitted. The automatic switching devices control the opening and closing of the door assembly. When the door assembly is opened, it disengages from the sealing ring, preventing direct friction and effectively protecting the sealing ring. When the door is closed, it is pressed vertically against the sealing ring, enhancing overall sealing and facilitating vacuuming inside the chamber. This prevents the battery from discharging under low vacuum conditions, improving safety. Furthermore, the entire process is automatically operated by a control cylinder, improving work efficiency. Although the furnace door is opened and closed by a cylinder, the automatic switch device has a complex structure, requiring both an active and a passive rotating rod. Furthermore, automatic switch devices need to be installed on both sides of the cabinet frame. Opening and closing the door relies on these automatic switch devices, resulting in a large footprint for the cabinet. Utility Model Content

[0004] In view of this, the present invention aims to provide an opening and closing component and a baking device to solve the problem that the opening and closing components in the prior art have complex structures and occupy a large space.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] On one hand, this utility model proposes an opening and closing assembly, which is disposed on the outside of a door assembly and used to open or close a baking chamber. The opening and closing assembly includes a base plate, a rotating plate, a cylinder, and a movable rod. The base plate is connected to the front panel of the baking chamber. The end of the base plate near the door assembly is the proximal end, and a first mounting seat is provided thereon. The end of the base plate away from the door assembly is the distal end, and a second mounting seat is provided thereon. The rotating plate is connected to the end of the door assembly near the opening and closing assembly, and a third mounting seat is provided thereon. The cylinder and the second mounting seat are hinged together. One end of the movable rod is connected to the cylinder and can extend and retract under the action of the cylinder. The other end of the movable rod is hinged to the third mounting seat. The door assembly is hinged to the first mounting seat. Under the action of the cylinder, the movable rod shortens and simultaneously drives the third mounting seat to rotate. Under the action of the movable rod and the third mounting seat, the door assembly can rotate around the hinge point between the movable rod and the first mounting seat, thereby opening the door assembly. Under the action of the cylinder, the movable rod extends and simultaneously drives the third mounting base to rotate, generating a clamping torque to push the door assembly to close. The door assembly can rotate around the hinge point between it and the first mounting base, thereby closing the door assembly.

[0007] Furthermore, along the direction from the cylinder to the movable rod, the movable rod is inclined forward. This creates space between the movable rod and the third mounting base, providing clearance for the opening and closing of the door assembly, and allowing the movable rod to retract into the cylinder without obstruction.

[0008] Furthermore, multiple baking chambers are vertically arranged within the baking chamber, each corresponding to a door assembly and an opening / closing assembly. The baking chambers are arranged in pairs and symmetrically distributed. Within each pair of baking chambers, multiple baking cavities are vertically distributed, with the left-side and right-side baking cavities corresponding one-to-one. The opening / closing assemblies controlling the left-side and right-side baking cavities are staggered vertically, with the opening / closing assemblies positioned between the paired baking chambers. This rational layout of components contributes to a more compact and space-saving overall device structure.

[0009] Furthermore, for the control assembly for opening and closing the left baking chamber, the proximal end of the base plate is connected to the right side of the front enclosure of the left baking chamber, the distal end of the base plate is connected to the left side of the front enclosure of the right baking chamber, the rotating plate is connected to the right side of the left door assembly, the right side of the left door assembly is hinged to the first mounting seat, the movable rod is hinged to the third mounting seat, and the end of the cylinder opposite to the movable rod is hinged to the second mounting seat.

[0010] Furthermore, for the control assembly for opening and closing the right baking chamber, the far end of the base plate is connected to the right side of the front enclosure of the left baking chamber, the near end of the base plate is connected to the left side of the front enclosure of the right baking chamber, the rotating plate is connected to the left side of the right door assembly, the left side of the right door assembly is hinged to the first mounting seat, the movable rod is hinged to the third mounting seat, and the end of the cylinder opposite to the movable rod is hinged to the second mounting seat.

[0011] Furthermore, the height of the distal end is ≤ half the height of the door assembly, and the height of the proximal end is ≤ the height of the door assembly.

[0012] Furthermore, a baffle is provided on the front side of the opening and closing component to cover the opening and closing component and improve its aesthetics.

[0013] Furthermore, a door assembly is provided at the front opening of the baking cavity, the left and right walls of the baking cavity are air inlet sidewalls, and the rear wall of the baking cavity is an air outlet sidewall, with air outlet holes provided on the air outlet sidewall. This dual-sided air inlet not only increases the air volume, improving drying efficiency and effect, and avoiding the problems of localized overheating or uneven drying caused by single-sided air inlet, but also weakens the airflow impact force, preventing hot air from blowing the lens and causing it to move. The rear-side air outlet facilitates the rapid and directional discharge of humid air after drying.

[0014] Furthermore, air inlet chambers are respectively provided on the left and right sides of the baking chamber, and an air outlet chamber is provided on the rear side. The space between the air inlet chamber and the air inlet sidewall forms an air inlet channel, and the space between the air outlet chamber and the air outlet sidewall forms an air outlet channel. The air inlet chambers gradually slope inward from near to far from the hot air inlet. When hot air enters the air inlet channel and flows through each baking chamber, the air volume further away from the air inlet decreases. The wind speed and pressure are adjusted by the gradually narrowing air duct to ensure that the wind speed and pressure are balanced throughout the air inlet channel, thereby allowing hot air to enter each baking chamber evenly, resulting in a consistent baking effect for lenses located in different baking chambers.

[0015] On the other hand, this utility model also proposes a baking device, which adopts the above-mentioned opening and closing components.

[0016] Compared with the prior art, the opening and closing component and baking device of this utility model have the following advantages:

[0017] (1) The opening and closing component has a simple structure, which can save space. Moreover, it is not necessary to set opening and closing components on both sides of the baking chamber frame. Only one opening and closing component can control the opening and closing of a door component.

[0018] (2) Under the action of the cylinder, the movable rod shortens and simultaneously drives the third mounting seat to rotate. Under the action of the movable rod and the third mounting seat, the door assembly can rotate around the hinge point between it and the first mounting seat, thereby opening the door assembly. Under the action of the cylinder, the movable rod extends and simultaneously drives the third mounting seat to rotate, generating a pressing torque to push the door assembly to close. The door assembly can rotate around the hinge point between it and the first mounting seat, thereby closing the door assembly. Attached Figure Description

[0045] It should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows for mutual communication; 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0046] like Figures 1 to 13 As shown, in order to realize the automated opening and closing of the door assembly 2, an opening and closing component 9 is provided on the outside of the door assembly 2 for opening or closing the baking chamber 6. The opening and closing component 9 includes a base plate 91, a rotating plate 92, a cylinder 93, and a movable rod 94. The base plate 91 is connected to the front panel of the baking chamber 6 for positioning the opening and closing component 9 to the baking chamber 6. The end of the base plate 91 near the door assembly 2 is the proximal end, and a first mounting seat 911 is provided thereon. The end of the base plate 91 away from the door assembly 2 is the distal end, and a second mounting seat 912 is provided thereon. The rotating plate 92 is connected to the end of the door assembly 2 near the opening and closing component 9. The rotating plate 92 is provided with a third mounting seat 923. The cylinder 93 and the second mounting seat 912 are hinged together. One end of the movable rod 94 is connected to the cylinder 93 and can extend and retract under the action of the cylinder 93. The other end of the movable rod 94 is hinged to the third mounting seat 923. The door assembly 2 is hinged to the first mounting seat 911.

[0047] Under the action of cylinder 93, the movable rod 94 shortens and simultaneously drives the third mounting base 923 to rotate. The door assembly 2, under the action of the movable rod 94, the third mounting base 923, and the rotating plate 92, can rotate around its hinge point with the first mounting base 911, thereby opening the door assembly 2. Under the action of cylinder 93, the movable rod 94 extends and simultaneously drives the third mounting base 923 to rotate, generating a clamping torque to push the door assembly 2 to close. The door assembly 2 can rotate around its hinge point with the first mounting base 911, thereby closing the door assembly 2. The opening and closing component 9 of this application has a simple structure, saves space, and eliminates the need to install opening and closing components 9 on both sides of the baking chamber 6 frame; only one opening and closing component 9 is needed to control the opening and closing of one door assembly 2.

[0048] Combination Figures 12 to 13The center positions of the third mounting base 923, the second mounting base 912, and the first mounting base 911 form a triangle. When the door assembly 2 opens or closes, the force generated by the movable rod 94 and the third mounting base 923 is concentrated at the end of the door assembly 2 closest to the first mounting base 911, causing the door assembly 2 to rotate around the first mounting base 911. When closing, there is a clamping torque around the first mounting base 911, which helps the door assembly 2 seal the opening, and when opening, the door assembly 2 can be easily pulled to rotate around the first mounting base 911. Using the opening and closing component 9 of this invention, the opening and closing of the door assembly 2 can be realized automatically and quickly, avoiding manual opening and closing of the door assembly 2.

[0049] As a preferred example of this utility model, the movable rod 94 is inclined forward along the direction from the cylinder 93 to the movable rod 94. This provides space between the movable rod 94 and the third mounting base 923, allowing clearance for the opening and closing of the door assembly 2, and allowing the movable rod 94 to retract into the cylinder 93 without obstruction.

[0050] The baking chamber 6 is used to bake the lens, curing the lens after adhesive application. To save space and increase the number of lenses baked at one time, in addition to setting multiple baking chambers 1 inside the baking chamber 6, multiple baking chambers 6 can also be set. As a preferred example of this utility model, the baking chambers 6 are arranged in pairs and symmetrically distributed from left to right. Multiple baking chambers 1 are vertically distributed in the paired baking chambers 6. The baking chamber 1 on the left and the baking chamber 1 on the right are arranged in a one-to-one correspondence. The opening and closing components 9 for controlling the opening and closing of the left baking chamber 1 and the opening and closing components 9 for controlling the right baking chamber 1 are arranged alternately, and the opening and closing components 9 are set between the two paired baking chambers 6. Through the reasonable layout of each component, the overall structure of the device is more compact and space-saving.

[0051] As a preferred example of this utility model, for the opening and closing assembly 9 controlling the left baking chamber 1, the proximal end of the base plate 91 is connected to the right side of the front enclosure of the left baking chamber 6, the distal end of the base plate 91 is connected to the left side of the front enclosure of the right baking chamber 6, the rotating plate 92 is connected to the right side of the left door assembly 2, the right side of the left door assembly 2 is hinged to the first mounting seat 911, the movable rod 94 is hinged to the third mounting seat 923, and the end of the cylinder 93 facing away from the movable rod 94 is hinged to the second mounting seat 912. The door assembly 2 located in the left baking chamber 1 flips to the right to open.

[0052] For the opening and closing assembly 9 controlling the right baking chamber 1, the far end of the base plate 91 is connected to the right side of the front enclosure of the left baking chamber 6, the near end of the base plate 91 is connected to the left side of the front enclosure of the right baking chamber 6, the rotating plate 92 is connected to the left side of the right door assembly 2, the left side of the right door assembly 2 is hinged to the first mounting seat 911, the movable rod 94 is hinged to the third mounting seat 923, and the end of the cylinder 93 facing away from the movable rod 94 is hinged to the second mounting seat 912. The door assembly 2 located in the right baking chamber 1 flips to the left to open. Since the opening directions of the door assemblies 2 located in the left and right baking chambers 1 are different, mutual interference when opening the doors simultaneously is avoided.

[0053] like Figures 1 to 5 As shown, a baking cavity 1 of this utility model is used to place and dry workpieces such as lenses. A door assembly 2 is provided at the front opening of the baking cavity 1. The side wall of the baking cavity 1 for air intake is an air intake side wall 14. A sliding plate 13 is provided on the inner side of the air intake side wall 14. The air intake side wall 14 has a first ventilation hole 11, and the sliding plate 13 has a second ventilation hole 12. The door assembly 2 can drive the sliding plate 13 to move back and forth. When the door assembly 2 is closed, the sliding plate 13 moves to a first position, and the first ventilation hole 11 and the second ventilation hole 12 are connected, allowing hot air to enter the baking cavity 1. When the door assembly 2 is opened, the sliding plate 13 moves to a second position, and the first ventilation hole 11 and the second ventilation hole 12 are misaligned, blocking hot air from entering the baking cavity 1.

[0054] This invention links the flow of hot air in the baking chamber 1 with the opening and closing of the door assembly 2. By changing the position of the sliding plate 13 through the opening and closing of the door assembly 2, it ensures that when the door assembly 2 is closed, the sliding plate 13 moves backward, creating a passage between the first ventilation hole 11 and the second ventilation hole 12, allowing hot air to smoothly enter and bake the lens in the space formed by the baking chamber 1 and the door assembly 2. When the door assembly 2 is open, the sliding plate 13 moves forward, blocking the first ventilation hole 11, preventing hot air from entering and stopping the baking process, thus preventing the waste of resources caused by hot air entering when the baking chamber 1 is open. Since the hot air does not come into contact with the environment at the opening, the hot air temperature will not drop drastically, avoiding the adverse effects of rapid temperature changes on the lens. At the same time, utilizing the side wall of the baking chamber 1 itself to form the first ventilation hole 11 simplifies the device.

[0055] It should be noted that the second position described in this invention refers to the situation where, when the door assembly 2 is open, the first ventilation hole 11 and the second ventilation hole 12 do not overlap at all, preventing hot air from entering the baking chamber 1. Of course, this invention also has other positions where the first ventilation hole 11 and the second ventilation hole 12 intersect, allowing a small amount of hot air to enter the baking chamber 1. The degree of overlap between the first ventilation hole 11 and the second ventilation hole 12 can be adjusted according to the actual condition of the lens and the temperature and quantity of the hot air.

[0056] Preferably, the air inlet sidewall 14 has a plurality of staggered first ventilation holes 11, and a connecting part is formed between the connected first ventilation holes 11. The sliding plate 13 has a plurality of staggered second ventilation holes 12, and the distance between adjacent first ventilation holes 11 is greater than the size of the second ventilation hole 12, that is, the size of the connecting part is greater than the size of the second ventilation hole 12, so as to ensure that the connecting part can block the second ventilation hole 12 and prevent hot air from entering.

[0057] As a preferred example of this utility model, the left and right side walls of the baking cavity 1 are air inlet side walls 14, the rear side wall of the baking cavity 1 is an air outlet side wall 15, and the air outlet side wall 15 has an air outlet hole 16.

[0058] Hot air enters from the left and right side walls, dries the lens, and then exits from the rear side wall. This dual-side air intake not only increases airflow, improving drying efficiency and effectiveness, and avoiding localized overheating or uneven drying caused by unilateral air intake, but also weakens the airflow impact, preventing the lens from shifting due to the hot airflow. The rear-side air exit facilitates the rapid and directional removal of the dried, humid air.

[0059] The sliding plate 13 is provided with a sliding groove 131, which is connected to the air inlet side wall 14 by a first fastener 17. This is used to position the sliding plate 13 in the baking cavity 1, and the sliding plate 13 can move along the sliding groove 131 when it moves, so as to prevent the position from shifting when sliding.

[0060] Furthermore, the sliding plate 13 is provided with grooves 131 at its four corners. The multiple grooves 131 improve the connection stability between the sliding plate 13 and the air inlet sidewall 14, preventing the sliding plate 13 from falling off. Since the grooves 131 are located at the four corners, they do not affect the opening or closing of the second ventilation hole 12. Furthermore, the first fastener 17 is a bolt, with the nut of the bolt located at the end of the groove 131 facing the inside of the baking cavity 1, enabling the sliding plate 13 to be positioned from the left and right directions.

[0061] The sliding plate 13 also includes a front bending plate 132 and a rear bending plate 133, which are bent inwards respectively. The inner side of the door assembly 2 is provided with an inwardly protruding pad 21. The rear bending plate 133 abuts against the rear side wall of the baking cavity 1 through a spring member 18. When the door assembly 2 is closed, the pad 21 contacts and presses the front bending plate 132 to push the sliding plate 13 to slide backwards, and the spring member 18 is compressed.

[0062] When the door assembly 2 is opened, the pad 21 and the front bending plate 132 separate, the spring 18 rebounds, and pushes the sliding plate 13 to reset, thereby separating the first ventilation hole 11 and the second ventilation hole 12. By utilizing the cooperation of the door assembly 2, the sliding plate 13, and the air outlet side wall 15, the relative positions of the first ventilation hole 11 and the second ventilation hole 12 are changed, thereby allowing hot air to enter or blocking hot air from entering.

[0063] As a preferred example of this utility model, such as Figure 2 As shown, the front bending plate 132 is provided with an adjusting screw 134, which is threadedly connected to the front bending plate 132. The adjusting screw 134 is used to change the distance at which the front end of the adjusting screw 134 extends out of the front bending plate 132, thereby adjusting the hot air intake volume.

[0064] Specifically, when the door assembly 2 is closed, the pad 21 contacts and presses against the adjusting screw 134, thereby moving the sliding plate 13. Since the distance by which the front end of the adjusting screw 134 extends beyond the front bent plate 132 is adjustable, the degree of overlap between the first ventilation hole 11 and the second ventilation hole 12 can be changed by adjusting the position of the adjusting screw 134, thus adjusting the hot air intake volume. For example, the less the distance the front end of the adjusting screw 134 extends beyond the front bent plate 132, the less distance the pad 21 pushes the sliding plate 13 backward, the less the degree of overlap between the first ventilation hole 11 and the second ventilation hole 12, and the less the hot air intake volume.

[0065] The pad 21 includes pad feet 211 on both sides and a protrusion 212 between the two pad feet 211. The pad feet 211 are connected to the door assembly 2 and are used to position the pad 21 on the door assembly 2. The protrusion 212 is used to push the sliding plate 13 to move.

[0066] To improve the sealing performance of the door assembly 2 when closing the baking cavity 1, a sealing ring is provided on the inner side of the door assembly 2. The door assembly 2 and the sealing ring cooperate to close the opening, thereby improving the sealing performance and preventing hot air from escaping from the opening.

[0067] A tray positioning block 10 is provided inside the baking cavity 1 for placing the tray. The tray has multiple mounting holes to hold multiple lenses, thereby achieving simultaneous drying of multiple lenses and improving drying efficiency.

[0068] To improve baking efficiency, the baking cavity 1 is vertically arranged with multiple baking chambers 6, such as... Figure 3As shown, air inlet chambers 4 are respectively arranged on the left and right sides of the baking chamber 6, and air outlet chambers 5 are arranged on the rear side. The space between the air inlet chambers 4 and the air inlet sidewall 14 forms an air inlet channel, and the space between the air outlet chambers 5 and the air outlet sidewall 15 forms an air outlet channel. The air inlet chambers 4 gradually slope inward from near to far from the hot air inlet 64. That is, the space of the air inlet chamber 4 is larger near the air inlet 64, and the space of the air inlet chamber 4 gradually decreases as it moves away from the air inlet 64, forming a gradual airflow channel. When hot air enters the airflow channel and flows through each baking chamber 1, the airflow volume decreases as it moves away from the air inlet 64. The wind speed and wind pressure are adjusted by the gradually narrowing airflow channel to ensure that the wind speed and pressure are balanced throughout the airflow channel, so that the hot air enters each baking chamber 1 evenly, and the lenses located in different baking chambers 1 have a consistent baking effect. The left and right side air intake method can avoid the problems of local overheating or uneven drying caused by unilateral air intake. The rear side air outlet method is conducive to the rapid and directional discharge of humid air after drying. Moreover, during the discharge process, the air can be distributed in all parts of the baking cavity 1 along the flow path from the two sides to the rear side, ensuring that lenses placed in different positions in the baking cavity 1 can be effectively dried.

[0069] The air inlet chamber 4 and the air outlet chamber 5 are not connected to each other to avoid mutual interference between the air inlet and outlet. The hot air flowing into the air inlet chamber 4 bakes the lens and forms humid air that flows back to the air outlet chamber 5 for recirculation, and is discharged through the air outlet channel 81. The discharged air can be heated by the heating device 65 to form hot air for continued use, thus creating an airflow circulation.

[0070] Furthermore, the air inlet 64 and the air outlet 81 of the baking chamber 6 are located on the same side. A heating device 65 is provided at the air inlet 64, which makes it convenient to use one heating device 65 to heat the air entering through the air inlet 64 and the air collected through the air outlet 81 at the same time, which helps to simplify the device and save resources.

[0071] Along the direction from near to far from the air inlet 64, the number of air outlet holes 16 on the corresponding air outlet sidewall 15 gradually increases in the multiple baking cavities 1. For baking cavities 1 farther from the air inlet 64, the incoming hot air velocity decreases. In order to better balance the air inlet velocity of baking cavities 1 at different locations, more air outlet holes 16 are set to increase the air outlet, accelerate the gas flow, and allow the heat-exchanged air to be discharged quickly, thereby improving the air inlet velocity.

[0072] Specifically, regarding this utility model Figures 5 to 6In this baking chamber 6, both the air inlet 64 and the air outlet 81 are located on the upper side. Along a top-to-bottom direction, the air inlet cavity 4 gradually tilts inward, and the number of corresponding air outlets 16 in the baking chamber 1 gradually increases. Utilizing both the tilted design of the air inlet cavity 4 and the increased number of air outlets 16, hot air can be evenly introduced into the baking chamber 1 at different locations, ensuring uniform heating of the lenses at all positions and consistent drying after baking.

[0073] Furthermore, the upper side of the baking chamber 6 is provided with a first volute 61, a second volute 62, a fan cavity 63 and a heating device 65. One end of the first volute 61 is connected to the fan cavity 63 and the other end is connected to the air inlet cavity 4 located on the left side. One end of the second volute 62 is connected to the fan cavity 63 and the other end is connected to the air inlet cavity 4 located on the right side.

[0074] Outside air enters the upper part of the baking chamber 6 through the air inlet 64, and after being heated to the preset temperature by the heating device 65, it becomes hot air. Under the action of the fan in the fan cavity 63, it enters the first volute 61 and the second volute 62 respectively. The hot air entering the first volute 61 enters multiple baking chambers 1 through the left air inlet cavity 4, and the hot air entering the second volute 62 enters multiple baking chambers 1 through the right air inlet cavity 4, thereby achieving simultaneous air intake on both sides of the baking chamber 1, and the air intake situation is consistent.

[0075] After drying and heat exchange, the air flows out through the air outlet 16 and is collected on the upper side of the baking chamber 6 by the fan 67. After being heated by the heating device 65, it is blown out by the fan and continues to be delivered to the first volute 61 and the second volute 62 for use.

[0076] A uniform air distribution plate 68 is provided at the connection between the first volute 61 and the air inlet cavity 4, and a uniform air distribution plate 68 is also provided at the connection between the second volute 62 and the air inlet cavity 4. The uniform air distribution plate 68 has multiple air inlet holes. This is used to disperse the hot airflow entering the air inlet cavity 4, distributing it as a gentle airflow into different baking chambers 1, achieving uniform airflow and ensuring consistent lens drying levels in different baking chambers 1, thus contributing to the uniformity of lens quality. The gentle airflow also reduces the impact of hot air on the lens, preventing lens displacement.

[0077] Furthermore, the fan cavity 63 is cylindrical, which facilitates the setting of two interfaces to communicate with the first volute 61 and the second volute 62 respectively, and the first volute 61 and the second volute 62 are symmetrically distributed to ensure that the hot air volume and wind speed entering the two volutes are the same.

[0078] The baking chamber 6 is arranged with a first partition 7 and a second partition 8 from top to bottom. The second partition 8 has openings. An air outlet channel 81 is formed between the upper sidewall of the uppermost baking chamber 1 and the second partition 8, and the air outlet channel 81 communicates with the air outlet cavity 5. The fan cavity 63 and the heating device 65 are located between the first partition 7 and the second partition 8. Air from multiple baking chambers 1 converges in the air outlet cavity 5 and, under the action of the fan 67, enters the space between the first partition 7 and the second partition 8 through the air outlet channel 81. The heating device 65 heats not only the air entering from the outside through the air inlet 64 but also the air from the air outlet channel 81.

[0079] The fan 67 and air inlet 64 are mounted on the first partition 7, which provides mounting points for both. The first partition 7 is also equipped with an exhaust pipe 71 to periodically remove volatile gases generated during the baking process, preventing them from affecting the lens quality. The fan 67 is connected to a fan.

[0080] Specifically, the heating device 65 is a heating tube, and multiple heating tubes can be set, with each heating tube being independently controllable. A temperature detection device is installed inside the baking chamber 6 to adjust the number of heating tubes in operation based on the detected temperature.

[0081] Furthermore, the front end of the air inlet cavity 4 forms the front enclosure of the baking chamber 6, and the bottom plate 91 is connected to the front enclosure of the air inlet cavity 4. Specifically, for the opening and closing assembly 9 that controls the left baking chamber 1, the proximal end of its bottom plate 91 is connected to the right air inlet cavity 4 of the left baking chamber 1, and the distal end of its bottom plate 91 is connected to the left air inlet cavity 4 of the right baking chamber 1. For the opening and closing assembly 9 that controls the right baking chamber 1, the proximal end of its bottom plate 91 is connected to the left air inlet cavity 4 of the right baking chamber 1, and the distal end of its bottom plate 91 is connected to the right air inlet cavity 4 of the left baking chamber 1.

[0082] In order to prevent the hot air flowing in the air inlet cavity 4 from affecting the opening and closing assembly 9, a third partition is provided between the front panel and the bottom plate 91 of the air inlet cavity 4. The third partition is used for heat insulation to reduce the adverse effects of high temperature on the opening and closing assembly 9.

[0083] To reduce heat loss during baking, the baking chamber 6 is surrounded by panels on all sides except the front, effectively insulating it and preventing operators from accidentally touching the chamber and getting burned. The panels also conceal the angled air inlet 4, making the baking chamber 6 more aesthetically pleasing.

[0084] The height of the distal end is ≤ half the height of the door assembly 2, and the height of the proximal end is ≤ the height of the door assembly 2. By limiting these dimensions, for the left and right baking cavities 1 located at the same height, two left and right opening / closing assemblies 9 can be staggered simultaneously without interfering with adjacent opening / closing assemblies 9. Specifically, regarding this utility model… Figure 13 In this configuration, the height of the far end is half the height of the door assembly 2, and the height of the near end is equal to the height of the door assembly 2. Besides ensuring proper allocation and placement of the two opening / closing components 9, the overall height of the opening / closing components 9 is essentially the same as the height of the door assembly 2, resulting in a more aesthetically pleasing and neat appearance. The height referred to here is the vertical dimension.

[0085] To further improve the aesthetics and overall appearance of the opening and closing assembly 9, a baffle is installed on the front side of the assembly to cover it and enhance its appearance. It should be noted that there is a gap between the baffle and the assembly 9, and the baffle must not interfere with the use of the assembly 9 and the door assembly 2.

[0086] A vertical fourth partition is installed between the paired baking chambers 6 to provide heat insulation, prevent mutual interference, and facilitate precise control of hot air temperature, thereby improving the drying effect.

[0087] like Figure 7 As shown, this utility model also proposes a baking device, which employs the aforementioned opening and closing component 9, which is disposed on the outside of the baking chamber 6. The baking device includes at least one set of baking chambers 6 symmetrically distributed from left to right and a housing 101 disposed on the outside of the baking chambers 6. Lenses to be baked are automatically fed into the respective baking cavities 1 within the baking chambers 6 by a robotic arm.

[0088] The baking device of this invention is not limited to baking lenses; it can also be used to bake other precision components. Due to its high degree of automation, it greatly saves manpower and material resources, and its small footprint facilitates production line improvements.

[0089] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
