Description

Technical Field

[0001] The present invention relates to the field of baking, and in particular to a baking chamber, a baking device and a baking method. Background Art

[0002] As a precision optical instrument, the lens needs to be glued and baked for curing during preparation. During baking, the lens is usually placed in the baking chamber of the baking device, and hot air is introduced into the baking chamber for curing. In view of the particularity of the lens, the temperature of the hot air in the baking chamber needs to be strictly controlled. However, in the process of opening the door assembly of the baking chamber and placing the lens in the baking chamber, the baking chamber is directly exposed to the outside, and a large amount of hot air gushes out, which not only causes a waste of hot air, but also the loss of hot air will affect the temperature in the entire baking device, causing the temperature to drop sharply. On the one hand, the temperature difference will cause the lens to debond or incompletely cure, thereby affecting the quality of the lens, and on the other hand, it will increase the load of the heating device that generates hot air.

[0003] CN108709377A A drying air duct system with three-dimensional air supply includes a box body, a first air valve, a first air door assembly, a second air valve, a third air valve, a second air door assembly and a fourth air valve; by closing the first air door assembly and the second air door assembly and controlling the opening and closing of the first air valve, the second air valve, the third air valve and the fourth air valve, the air path of the drying inner cavity is made a penetrating air supply air path; by closing the first air valve, the second air valve, the third air valve and the fourth air valve and opening the first air door assembly and the second air door assembly, the air path of the drying inner cavity is made a parallel air supply air path, wherein, by adjusting the first air door assembly or the second air door assembly to switch between the preset fully open state, the half-open state and the closed state, the air intake volume of the first air door assembly or the air outlet volume of the second air door assembly is adjusted; by providing the penetrating air supply air path and the parallel air supply air path, three-dimensional air supply is realized to improve the drying chamber. Although the relative positions of the ventilation holes set on the damper static blade and the damper dynamic blade can be adjusted to adjust the overlapping area of ​​the ventilation holes, additional hand levers and locking pins are required, making the entire device more complicated, and it is impossible to establish a connection between the change in the relative position of the ventilation holes and the opening and closing of the door to release and pick up materials, which has limitations in use. Summary of the invention

[0004] In view of this, the present invention aims to propose a baking chamber, a baking device and a baking method to solve the problem in the prior art that it is impossible to establish a linkage between the hot air flow and the opening and closing of the door component, so that when the opening and closing component is opened to discharge the material, a large amount of hot air in the baking chamber gushes out and causes loss.

[0005] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0006] On the one hand, the present invention proposes a baking chamber, wherein a door assembly is arranged at the front opening of the baking chamber, the side wall of the baking chamber for air inlet is an air inlet side wall, a sliding plate is arranged at the inner side of the air inlet side wall, the air inlet side wall is provided with a first ventilation hole, the sliding plate is provided with a second ventilation hole, the door assembly can drive the sliding plate to move back and forth, when the door assembly is closed, the sliding plate moves to a first position, the first ventilation hole and the second ventilation hole are connected, and hot air enters the baking chamber, when the door assembly is opened, the sliding plate moves to a second position, the first ventilation hole and the second ventilation hole are misaligned, and hot air is blocked from entering the baking chamber. The present invention links the hot air flow of the baking chamber with the opening and closing of the door assembly, and changes the position of the sliding plate by the opening and closing of the door assembly, so that when the door assembly is closed, the sliding plate moves backward, the first ventilation hole and the second ventilation hole form a passage, and the hot air smoothly enters and bakes the lens in the space formed by the baking chamber and the door assembly; when the door assembly is opened, the sliding plate moves forward, the first ventilation hole is blocked, the hot air cannot enter and stops baking, and the hot air entering the baking chamber in an open state is prevented from wasting resources. Since the hot air will not contact the environment at the opening, the hot air temperature will not drop sharply, avoiding the adverse effect of too fast temperature change on the lens. At the same time, the first ventilation hole is formed by the side wall of the baking chamber itself, which is conducive to simplifying the device.

[0007] Furthermore, the left and right walls of the baking chamber are air inlet side walls, and the rear side wall of the baking chamber is an air outlet side wall, and the air outlet side wall is provided with air outlet holes. Hot air enters from the left and right side walls, dries the lens, and then flows out from the rear side wall. The air inlet on both sides can not only increase the air intake, improve the drying efficiency and drying effect, and avoid the problem of local overheating or uneven drying caused by unilateral air inlet, but also the relative air inlet on both sides can weaken the impact of the airflow, and avoid the hot airflow blowing the lens and causing the lens to move. The rear air outlet is conducive to the rapid and directional discharge of the humid air after drying.

[0008] Furthermore, the sliding plate is provided with a sliding groove, and the sliding groove is connected to the air inlet side wall by a first fastener, so as to position the sliding plate in the baking chamber, and the sliding plate can move along the sliding groove when moving, so as to prevent position deviation during sliding.

[0009] Furthermore, the sliding plate further comprises a front bending plate and a rear bending plate, the front bending plate and the rear bending plate are bent inwards respectively, a pad protruding inwards is provided on the inner side of the door assembly, the rear bending plate abuts against the rear wall of the baking chamber through a spring member, and when the door assembly is closed, the pad contacts and squeezes the front bending plate to push the sliding plate to slide to the rear side, and the spring member is squeezed. When the door assembly is opened, the pad separates from the front bending plate, the spring member rebounds, and pushes the sliding plate to reset, so as to separate the first ventilation hole from the second ventilation hole. By utilizing the cooperation of the door assembly, the sliding plate and the air outlet side wall, the relative positions of the first ventilation hole and the second ventilation hole are changed, thereby allowing hot air to enter or blocking hot air from entering.

[0010] Furthermore, the front bending plate is provided with an adjusting screw, and the adjusting screw is threadedly connected to the front bending plate, so as to change the distance that the front end of the adjusting screw extends out of the front bending plate, thereby adjusting the hot air intake volume.

[0011] Furthermore, the baking chamber is vertically provided with a plurality of baking chambers, and an opening and closing assembly is provided on the outer side of the door assembly for opening or closing the door assembly, and the opening and closing assembly includes a bottom plate, a rotating plate, a cylinder and a movable rod, the bottom plate is connected to the front panel of the baking chamber, the end of the bottom plate close to the door assembly is the proximal end, and a first mounting seat is provided, the end of the bottom plate away from the door assembly is the distal end, and a second mounting seat is provided, the rotating plate is connected to an end of the door assembly close to the opening and closing assembly, the rotating plate is provided with a third mounting seat, the cylinder and the second mounting seat are hinged, one end of the movable rod is connected to the cylinder and can be extended and retracted under the action of the cylinder, the other end of the movable rod is hinged to the third mounting seat, and the door assembly is hinged to the first mounting seat. Under the action of the cylinder, the movable rod is shortened and synchronously drives the third mounting seat to rotate, and the door assembly can rotate around the hinge between the movable rod and the first mounting seat under the action of the movable rod and the third mounting seat, thereby opening the door assembly. Under the action of the cylinder, the movable rod extends and synchronously drives the third mounting seat to rotate, generating a compression torque to push the door assembly to close. The door assembly can rotate around the hinge between it and the first mounting seat, thereby closing the door assembly.

[0012] Furthermore, the baking chambers are arranged in pairs and are symmetrically distributed on the left and right. The baking cavity on the left and the baking cavity on the right are arranged one by one. The opening and closing components for controlling the left baking cavity and the opening and closing components for controlling the right baking cavity are staggered up and down, and the opening and closing components are arranged between the two baking chambers arranged in pairs.

[0013] Furthermore, the baking chamber is vertically provided with a plurality of baking chambers, and an air inlet cavity is respectively provided on the left and right sides of the baking chamber, and an air outlet cavity is provided on the rear side. The space between the air inlet cavity and the air inlet side wall forms an air inlet channel, and the space between the air outlet cavity and the air outlet side wall forms an air outlet channel. Along the direction from near to far from the hot air inlet, the air inlet cavity gradually tilts inward, and the number of air outlet holes corresponding to the air outlet side walls of the plurality of baking chambers gradually increases. The wind speed and wind pressure are adjusted by the gradually narrowing gradual air duct to ensure that the wind speed and pressure in the entire air inlet air duct are balanced, so that the hot air enters each baking chamber evenly, and the lenses located in different baking chambers have a consistent baking effect. For the baking chamber far away from the air inlet, the speed of the incoming hot air becomes smaller. In order to better balance the air inlet speed of the baking chambers at different positions, more air outlet holes are provided to increase the air outlet, accelerate the gas flow, and quickly discharge the air after heat exchange, so as to improve the air inlet speed.

[0014] On the other hand, the present invention also provides a baking device, the baking device adopts the above-mentioned baking cavity, the baking device comprises a transport assembly, a shell and at least one set of baking chambers symmetrically distributed on the left and right, the baking chambers and the transport assembly are arranged in a space enclosed by the shell. Since the transport assembly is integrated in the shell, the entire structure of the baking device is more compact and space can be saved.

[0015] On the other hand, the present invention also provides a baking method of the baking device, comprising the following steps:

[0016] S1. The door assembly is closed, hot air enters each baking chamber for preheating, and after reaching the set temperature, the transport assembly starts to load the material;

[0021] S6. Return to step S2, execute the next cycle, and transport the tray containing the lens to be baked to the next baking chamber.

[0022] Compared with the prior art, the baking chamber, baking device and baking method of the present invention have the following advantages:

[0023] (1) The hot air flow in the baking chamber is linked to the opening and closing of the door assembly, and the position of the sliding plate is changed by the opening and closing of the door assembly, so that when the door assembly is closed, the sliding plate moves backward, the first ventilation hole and the second ventilation hole form a passage, and the hot air smoothly enters and bakes the lens in the space formed by the baking chamber and the door assembly; when the door assembly is opened, the sliding plate moves forward, the first ventilation hole is blocked, and the hot air cannot enter and stops baking, thereby preventing the waste of resources caused by the entry of hot air in the baking chamber when it is open. Since the hot air will not come into contact with the environment at the opening, the hot air temperature will not drop sharply, avoiding the adverse effect of excessive temperature changes on the lens. At the same time, the first ventilation hole is formed by the side wall of the baking chamber itself, which is conducive to simplifying the device.

[0055] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In addition, the directions involved in the following specific embodiments are briefly described: the directions or positional relationships indicated by "front", "rear", "upper", "lower", "left", "right", "top", "bottom" and the like mentioned in the embodiments refer to the directions or positional relationships shown in the accompanying drawings, and the term "on..." refers to being directly or indirectly supported by... elements.

[0056] It should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0057] like Figures 1 to 5As shown, a baking chamber 1 of the present invention is used for placing and drying workpieces such as lenses, a door assembly 2 is arranged at the front opening of the baking chamber 1, the side wall of the baking chamber 1 for air inlet is an air inlet side wall 14, a sliding plate 13 is arranged on the inner side of the air inlet side wall 14, the air inlet side wall 14 is provided with a first ventilation hole 11, the sliding plate 13 is provided with 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 the first position, the first ventilation hole 11 and the second ventilation hole 12 are connected, and hot air enters the baking chamber 1, when the door assembly 2 is opened, the sliding plate 13 moves to the second position, the first ventilation hole 11 and the second ventilation hole 12 are misaligned, and hot air is blocked from entering the baking chamber 1.

[0058] The present invention links the hot air flow of the baking chamber 1 with the opening and closing of the door assembly 2, and uses the opening and closing of the door assembly 2 to change the position of the sliding plate 13, so that when the door assembly 2 is closed, the sliding plate 13 moves backward, the first ventilation hole 11 and the second ventilation hole 12 form a passage, and the hot air smoothly enters and bakes the lens in the space formed by the baking chamber 1 and the door assembly 2; when the door assembly 2 is opened, the sliding plate 13 moves forward, the first ventilation hole 11 is blocked, and the hot air cannot enter and stops baking, thereby preventing the hot air from entering the baking chamber 1 when it is open, causing waste of resources. Since the hot air will not contact the environment at the opening, the hot air temperature will not drop sharply, avoiding the adverse effect of too fast temperature changes on the lens. At the same time, the first ventilation hole 11 is formed by the side wall of the baking chamber 1 itself, which is conducive to simplifying the device.

[0059] It should be noted that the second position described in the present invention means that when the door assembly 2 is opened, the first ventilation hole 11 and the second ventilation hole 12 do not overlap at all, and the hot air cannot enter the baking chamber 1. Of course, the present invention also has other positions. In other positions, the first ventilation hole 11 and the second ventilation hole 12 intersect, and a small amount of hot air can enter the baking chamber 1. The degree of intersection and overlap of the first ventilation hole 11 and the second ventilation hole 12 can be adjusted according to the actual situation of the lens and the temperature and weight of the hot air to adjust the air intake.

[0060] Preferably, the air inlet side wall 14 is provided with a plurality of staggered first ventilation holes 11, and a connecting portion is formed between the connected first ventilation holes 11. The sliding plate 13 is provided with a plurality of staggered second ventilation holes 12, and the spacing between adjacent first ventilation holes 11 is larger than the size of the second ventilation holes 12, that is, the size of the connecting portion is larger than the size of the second ventilation holes 12, so as to ensure that the connecting portion can block the second ventilation holes 12 and prevent hot air from entering.

[0061] As a preferred example of the present invention, the left and right walls of the baking chamber 1 are air inlet side walls 14, and the rear side wall of the baking chamber 1 is an air outlet side wall 15, and the air outlet side wall 15 is provided with an air outlet hole 16. Hot air enters from the left and right side walls, dries the lens, and then flows out from the rear side wall. The air intake on both sides can not only increase the air intake volume, improve the drying efficiency and drying effect, and avoid the problem of local overheating or uneven drying caused by unilateral air intake, but also the relative air intake on both sides can weaken the impact of the airflow, and avoid the hot airflow blowing the lens and causing the lens to move. The rear air outlet method is conducive to the rapid and directional discharge of the humid air after drying.

[0062] The sliding plate 13 is provided with a sliding groove 131, and the sliding groove 131 and the air inlet side wall 14 are connected by a first fastener 17, which is used to position the sliding plate 13 in the baking chamber 1, and the sliding plate 13 can move along the sliding groove 131 when moving to prevent position displacement during sliding.

[0063] Furthermore, the four corners of the sliding plate 13 are respectively provided with slide grooves 131. The provision of multiple slide grooves 131 improves the connection stability between the sliding plate 13 and the air inlet side wall 14, and prevents the sliding plate 13 from falling off. Since the slide grooves 131 are provided at the four corners, the opening or closing of the second ventilation hole 12 will not be affected. Furthermore, the first fastener 17 is a bolt, and the nut of the bolt is provided at one end of the slide groove 131 facing the inner side of the baking chamber 1, so that the sliding plate 13 can be positioned from the left and right directions.

[0064] The sliding plate 13 further includes a front bending plate 132 and a rear bending plate 133, which are bent inwards respectively. A pad 21 protruding inwards is arranged on the inner side of the door assembly 2, and the rear bending plate 133 abuts against the rear wall of the baking chamber 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 pressed. When the door assembly 2 is opened, the pad 21 and the front bending plate 132 are separated, the spring member 18 rebounds, and pushes the sliding plate 13 to reset, so as to separate the first ventilation hole 11 and the second ventilation hole 12. By using the cooperation of the door assembly 2, the sliding plate 13 and the air outlet side wall 15, the relative position of the first ventilation hole 11 and the second ventilation hole 12 is changed, so that hot air can enter or be blocked from entering.

[0065] As a preferred example of the present invention, Figure 2As shown, the front side bending plate 132 is provided with an adjusting screw 134, and the adjusting screw 134 is threadedly connected with the front side bending plate 132, and is used to change the distance that the front end of the adjusting screw 134 extends out of the front side bending plate 132, so as to adjust the hot air intake. Specifically, when the door assembly 2 is closed, the cushion block 21 contacts and presses the adjusting screw 134 to drive the sliding plate 13 to move. Since the distance that the front end of the adjusting screw 134 extends out of the front side bending plate 132 is adjustable, the overlap degree of the first ventilation hole 11 and the second ventilation hole 12 can be changed by adjusting the position of the adjusting screw 134, so as to adjust the hot air intake. For example, the less the distance that the front end of the adjusting screw 134 extends out of the front side bending plate 132, the less the distance that the cushion block 21 pushes the sliding plate 13 to move backward, the overlap degree of the first ventilation hole 11 and the second ventilation hole 12 is correspondingly reduced, and the hot air intake is also reduced.

[0066] The cushion block 21 includes cushion feet 211 on both sides and a protrusion 212 between the two cushion feet 211 . The cushion feet 211 are connected to the door assembly 2 to position the cushion block 21 on the door assembly 2 . The protrusion 212 is used to push the sliding plate 13 to move.

[0067] In order to improve the sealing performance when the door assembly 2 closes the baking chamber 1, a sealing ring is arranged 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 overflowing from the opening.

[0068] A tray positioning block 10 is provided inside the baking chamber 1 for placing a tray. The tray is provided with a plurality of mounting holes for placing a plurality of lenses, thereby achieving synchronous drying of the plurality of lenses and improving drying efficiency.

[0069] In order to improve the baking efficiency, the baking cavity 1 is vertically provided with a plurality of baking chambers 6, such as Figure 3As shown, the left and right sides of the baking chamber 6 are respectively provided with air inlet cavities 4, and the rear side is provided with an air outlet cavity 5. The space between the air inlet cavity 4 and the air inlet side wall 14 forms an air inlet channel, and the space between the air outlet cavity 5 and the air outlet side wall 15 forms an air outlet channel. The air inlet cavity 4 gradually tilts inward along the direction from near to far from the hot air inlet 64. That is, the space of the air inlet cavity 4 is larger near the air inlet 64, and as it gradually moves away from the air inlet 64, the space of the air inlet cavity 4 continues to decrease, and the air inlet channel forms a gradual air channel. When hot air enters the air inlet channel and flows through each baking cavity 1, the air intake volume away from the air inlet 64 will become less, and the wind speed and wind pressure are adjusted by the gradually narrowing gradual air channel to ensure that the wind speed and pressure in the entire air inlet duct are balanced, so that the hot air enters each baking cavity 1 evenly, and the lenses located in different baking cavities 1 have a consistent baking effect. The air intake method on the left and right sides can avoid the problem of local overheating or uneven drying caused by unilateral air intake. The air outlet method on the rear side is conducive to the rapid and directional discharge of the moist air after drying. In the process of exhausting the air, the flow path entering from both sides and flowing out from the rear side can be distributed to various places in the baking chamber 1, ensuring that the lenses placed at different positions in the baking chamber 1 can be effectively dried.

[0070] The air inlet cavity 4 and the air outlet cavity 5 are not connected to each other to avoid the inlet and outlet air from affecting each other. After the hot air flowing into the air inlet cavity 4 bakes the lens, it forms moist air and flows to the air outlet cavity 5 for return air 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, forming an air flow cycle.

[0071] Furthermore, the air inlet 64 and the air outlet duct 81 of the baking chamber 6 are located on the same side, and a heating device 65 is provided at the air inlet 64, so that the air entering the air inlet 64 and the air collected through the air outlet duct 81 can be heated simultaneously by using a set of heating devices 65, which is conducive to simplifying the device and saving resources.

[0072] The number of the air outlet holes 16 of the corresponding air outlet side wall 15 of the plurality of baking chambers 1 increases gradually from near to far from the air inlet 64. For the baking chamber 1 far from the air inlet 64, the speed of the incoming hot air becomes smaller. In order to better balance the air inlet speed of the baking chamber 1 at different positions, more air outlet holes 16 are provided to increase the air outlet, speed up the gas flow, and quickly discharge the air after heat exchange, so as to improve the air inlet speed.

[0073] Specific to the present invention Figures 5 and 6Among them, the air inlet 64 and the air outlet flow channel 81 are both arranged on the upper side of the baking chamber 6. Along the direction from top to bottom, the air inlet cavity 4 gradually inclines inwards, and the number of air outlet holes 16 corresponding to the baking cavity 1 gradually increases. By using the dual settings of the inclined arrangement of the air inlet cavity 4 and the number of air outlet holes 16, hot air can enter the baking cavities 1 at different positions evenly, ensuring that the lenses at each position are heated evenly and have the same drying degree after drying.

[0074] Furthermore, a first volute 61, a second volute 62, a fan cavity 63 and a heating device 65 are arranged on the upper side of the baking chamber 6. One end of the first volute 61 is communicated with the fan cavity 63, and the other end is communicated with the air inlet cavity 4 on the left side. One end of the second volute 62 is communicated with the fan cavity 63, and the other end is communicated with the air inlet cavity 4 on the right side.

[0075] External air enters the upper side of the baking chamber 6 through the air inlet 64, forms hot air after being heated to a preset temperature by the heating device 65, and respectively enters the first volute 61 and the second volute 62 under the action of the fan in the fan cavity 63. The hot air entering the first volute 61 enters multiple baking cavities 1 through the air inlet cavity 4 on the left side, and the hot air entering the second volute 62 enters multiple baking cavities 1 through the air inlet cavity 4 on the right side, thereby realizing simultaneous air inlet on the left and right sides of the baking cavity 1 and having the same air inlet situation.

[0076] The air that has completed heat exchange after drying flows out along the air outlet holes 16, converges to the upper side of the baking chamber 6 under the action of the fan 67, and after being heated by the heating device 65, is blown out by the fan and continues to be conveyed to the first volute 61 and the second volute 62 for use.

[0077] An air distribution plate 68 is arranged at the connection between the first volute 61 and the air inlet cavity 4, and an air distribution plate 68 is arranged at the connection between the second volute 62 and the air inlet cavity 4. The air distribution plate 68 is provided with a plurality of air inlet holes. It is used to disperse the hot air flow entering the air inlet cavity 4 and enter different baking cavities 1 in the form of a gentle air flow, realizing uniform air outlet, ensuring that the drying degrees of the lenses in different baking cavities 1 are the same, and being beneficial to ensuring the uniformity of the lens quality. The gentle air flow can reduce the impact of the hot air on the lens and avoid the displacement of the lens.

[0078] Furthermore, the fan cavity 63 is cylindrical, which is convenient for arranging two interfaces to be respectively communicated with the first volute 61 and the second volute 62, and the first volute 61 and the second volute 62 are symmetrically distributed, ensuring that the air volume and air speed of the hot air entering the two volutes are the same.

[0079] The baking chamber 6 is provided with a first partition 7 and a second partition 8 in sequence from top to bottom, and an opening is provided on the second partition 8. There is a gap between the upper side wall of the baking cavity 1 located at the uppermost side and the second partition 8 to form an air outlet channel 81, and the air outlet channel 81 is connected to the air outlet cavity 5. The fan cavity 63 and the heating device 65 are provided between the first partition 7 and the second partition 8. The air outlets of the plurality of baking cavities 1 are collected in the air outlet cavity 5, and enter the space between the first partition 7 and the second partition 8 through the air outlet channel 81 under the action of the fan 67. In addition to heating the air entering from the outside through the air inlet 64, the heating device 65 also heats the air from the air outlet channel 81.

[0080] The blower 67 and the air inlet 64 are arranged on the first partition 7, and the first partition 7 provides a mounting position for the two. The first partition 7 is also provided with an exhaust pipe 71, which is used to regularly exhaust the volatile gas generated during the baking process to avoid affecting the quality of the lens. The blower 67 is connected to a fan.

[0081] Specifically, the heating device 65 is a heating tube, and the number of heating tubes can be set to multiple, and the multiple heating tubes can be controlled independently. A temperature detection device is set in the baking chamber 6, and the working number of the heating tubes is reasonably adjusted according to the temperature conditions detected.

[0082] like Figures 8 to 13 As shown, in order to realize automatic opening and closing of the door assembly 2, an opening and closing assembly 9 is arranged on the outer side of the door assembly 2 for opening or closing the door assembly 2, and the opening and closing assembly 9 includes a bottom plate 91, a rotating plate 92, a cylinder 93 and a movable rod 94. The bottom plate 91 is connected to the front panel of the baking chamber 6 for positioning the opening and closing assembly 9 and connecting it to the baking chamber 6. The end of the bottom plate 91 close to the door assembly 2 is the proximal end, and a first mounting seat 911 is arranged thereon, and the end of the bottom plate 91 away from the door assembly 2 is the distal end, and a second mounting seat 912 is arranged thereon. The rotating plate 92 is connected to the end of the door assembly 2 close to the opening and closing assembly 9, and a third mounting seat 923 is arranged on the rotating plate 92. The cylinder 93 is hinged to the second mounting seat 912. One end of the movable rod 94 is connected to the cylinder 93 and can be extended and retracted under the action of the cylinder 93. The other end of the movable rod 94 is hinged to the third mounting seat 923, and the door assembly 2 is hinged to the first mounting seat 911.

[0083] Under the action of the cylinder 93, the movable rod 94 shortens and synchronously drives the third mounting seat 923 to rotate. Under the action of the movable rod 94, the third mounting seat 923 and the rotating plate 92, the door assembly 2 can rotate around the hinge between it and the first mounting seat 911, thereby opening the door assembly 2. Under the action of the cylinder 93, the movable rod 94 extends and synchronously drives the third mounting seat 923 to rotate, generating a compression torque to push the door assembly 2 to close. The door assembly 2 can rotate around the hinge between it and the first mounting seat 911, thereby closing the door assembly 2 and preventing hot air from overflowing.

[0084] Combination Figures 12-13 , the center positions of the third mounting seat 923, the second mounting seat 912 and the first mounting seat 911 are connected to form a triangle. When the door assembly 2 is opened or closed, the force generated by the movable rod 94 and the third mounting seat 923 is concentrated on the end of the door assembly 2 close to the first mounting seat 911, and the door assembly 2 rotates with the first mounting seat 911 as the center. When closing the door, there is a compacting torque around the first mounting seat 911, which is conducive to sealing the opening of the door assembly 2, and when opening the door, the door assembly 2 can be easily pulled to rotate around the first mounting seat 911. The opening and closing assembly 9 of the present invention can automatically and quickly realize the opening and closing of the door assembly 2, avoiding manual opening and closing of the door assembly 2.

[0085] As a preferred example of the present invention, the movable rod 94 is tilted forward along the direction from the cylinder 93 to the movable rod 94. Thus, there is a space between the movable rod 94 and the third mounting seat 923, which is used to reserve a space for the door assembly 2 to open and close, and the movable rod 94 can be retracted into the cylinder 93 without being blocked.

[0086] In order to save space and increase the number of disposable baking lenses, in addition to arranging multiple layers of baking chambers 1 in the baking chamber 6, multiple baking chambers 6 can also be arranged. As a preferred example of the present invention, the baking chambers 6 are arranged in pairs and are symmetrically distributed left and right. Multiple baking chambers 1 are vertically distributed in the baking chambers 6 arranged in pairs, and the baking chambers 1 on the left and the baking chambers 1 on the right are arranged one by one. The opening and closing components 9 for controlling the baking chambers 1 on the left and the opening and closing components 9 for controlling the baking chambers 1 on the right are staggered up and down, and the opening and closing components 9 are arranged between the two baking chambers 6 arranged in pairs. The reasonable layout of each component is conducive to making the entire device structure more compact and saving space.

[0087] As a preferred example of the present invention, for the opening and closing assembly 9 controlling the left baking chamber 1, the proximal end of the bottom plate 91 is connected to the right side of the front panel of the left baking chamber 6, the distal end of the bottom plate 91 is connected to the left side of the front panel 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 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 is flipped toward the right to open.

[0088] For the opening and closing assembly 9 for controlling the right baking chamber 1, the distal end of the bottom plate 91 is connected to the right side of the front panel of the left baking chamber 6, the proximal end of the bottom plate 91 is connected to the left side of the front panel 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 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 toward the left side to open. Since the door assemblies 2 located in the left and right baking chambers 1 have different opening directions, mutual interference when opening the doors at the same time is avoided.

[0089] Furthermore, the front end of the air inlet cavity 4 forms the front panel of the baking chamber 6, and the bottom plate 91 is connected to the front panel of the air inlet cavity 4. Specifically, for the opening and closing component 9 that controls the left baking cavity 1, the proximal end of the bottom plate 91 is connected to the right air inlet cavity 4 of the left baking cavity 1, and the distal end of the bottom plate 91 is connected to the left air inlet cavity 4 of the right baking cavity 1. For the opening and closing component 9 that controls the right baking cavity 1, the proximal end of the bottom plate 91 is connected to the left air inlet cavity 4 of the right baking cavity 1, and the distal end of the bottom plate 91 is connected to the right air inlet cavity 4 of the left baking cavity 1.

[0090] In order to prevent the hot air flowing in the air inlet cavity 4 from affecting the opening and closing component 9, a third partition is arranged between the front panel and the bottom plate 91 of the air inlet cavity 4, and the third partition is used for heat insulation treatment to reduce the adverse effect of high temperature on the opening and closing component 9.

[0091] In order to reduce the heat loss to the outside during baking, the outer periphery of the baking chamber 6 is provided with a panel except the front side, which is effective for heat insulation and can also prevent operators from accidentally touching the baking chamber 6 and causing burns. The panel can shield the inclined air inlet cavity 4, making the baking chamber 6 more beautiful.

[0092] The height of the far end is ≤ half of the height of the door assembly 2, and the height of the near end is ≤ the height of the door assembly 2. By limiting the size, for the left and right baking chambers 1 located at the same height, the left and right opening and closing assemblies 9 can be staggered and placed at the same time without interfering with the adjacent opening and closing assemblies 9. Fig.13 In the figure, the height of the far end is half of the height of the door assembly 2, and the height of the near end is the height of the door assembly 2. In addition to being able to reasonably allocate and place the left and right opening and closing assemblies 9, the overall height of the opening and closing assembly 9 is basically consistent with the height of the door assembly 2, making the appearance more beautiful and neat. The height mentioned here refers to the height dimension in the up and down direction.

[0093] In order to further improve the aesthetics and integrity of the opening and closing assembly 9, a baffle is provided on the front side of the opening and closing assembly 9 to cover the opening and closing assembly 9. It should be noted that there is a gap between the baffle and the opening and closing assembly 9, and it cannot affect the use of the opening and closing assembly 9 and the door assembly 2.

[0094] A fourth vertical partition is provided between the paired baking chambers 6 to play a role of heat insulation and prevent mutual influence, which is beneficial to the precise control of the hot air temperature, thereby improving the drying effect.

[0095] like Figure 7 and Figures 14 to 16 As shown, the present invention also proposes a baking device, which includes a transport component 3, a shell and at least one group of baking chambers 6 symmetrically distributed on the left and right, and the baking chambers 6 and the transport component 3 are arranged in a space enclosed by the shell. The transport component 3 is used to move the tray on which the lens is placed into the baking chamber 1 for heating and baking. Since the transport component 3 is integrated in the shell, the entire structure of the baking device is more compact and can save space. According to the different baking time requirements of customers, multiple groups of baking chambers 6 symmetrically distributed on the left and right can be set. For example, the output time of a production line is t time to dry a lens, and a group of baking chambers 6 can meet this requirement. When the customer needs to double the baking time, another group of baking chambers 6 symmetrically distributed on the left and right can be added.

[0096] An outlet 101 is provided on one side of the housing, so that the transport assembly 3 can extend out of the baking device and move to the loading platform where the lens is stored to take the material. After taking the material, the transport assembly 3 drives the material tray with the lens to return to the baking device and transport it to each baking chamber 1 for baking.

[0097] The transport assembly 3 is provided with a moving part 31, a rotating part 32 and a telescopic part 33 in order from top to bottom. One side of the rotating part 32 is connected to the moving part 31, and the other side is connected to the telescopic part 33. The telescopic part 33 is used to pick up the material tray. The moving part 31 can drive the transport assembly 3 to move linearly in at least two directions. The rotating part 32 can drive the telescopic part 33 to rotate. The telescopic part 33 can move back and forth in a linear direction. The transport assembly 3 of the present invention can drive the material tray to move in different directions through the mutual cooperation of various components, so as to smoothly realize loading and unloading, and can be applied to different occasions, and is easy to promote and use.

[0098] As a preferred example of the present invention, the telescopic part 33 includes a support plate 333, and the first moving member 331 and the second moving member 332 are respectively arranged on the upper and lower sides of the support plate 333, the first moving member 331 and the second moving member 332 are connected, and the two move synchronously on the support plate 333 in the direction away from each other, and the second moving member 332 is used for placing the material tray.

[0099] In order to facilitate picking up and placing the tray, the second moving member 332 is connected to the picking portion. The picking portion is configured as a flat plate to match the tray. The picking portion can also be configured as a clamping shape, a gripper shape, or other shapes or structures to better match the tray.

[0100] When the first moving member 331 moves in the direction away from the picking portion, the second moving member 332 extends in the opposite direction, and the two move away from each other in this process, and the distance is the farthest, and the picking portion is sent out. When the first moving member 331 returns, the second moving member 332 retracts in the opposite direction, and the two move closer to each other in this process, and the distance is the shortest. Thus, the telescopic portion 33 has a long extension stroke, which is convenient for moving to different places to pick up materials, and has a small rotation radius, and can rotate in the limited space in the shell without hitting other parts.

[0101] Specifically, the leftmost position of the support plate 333 is the left limit position, and the rightmost position is the right limit position. When the transport component 3 needs to pick up the tray, the first moving member 331 moves to the right limit position, and correspondingly, the second moving member 332 moves to the left and extends to the left limit position. The distance between the two is the longest. The second moving member 332 has the largest extension distance, which is convenient for moving to the loading platform to pick up the tray. When the transport component 3 needs to deliver the picked-up tray to the baking chamber 1, the first moving member 331 moves to the left limit position, and correspondingly, the second moving member 332 moves to the right and retracts to the right limit position to prevent the second moving member 332 from extending too much from the support plate 333. At this time, the distance between the two is the shortest. When the rotating part 32 is used to drive the telescopic part 33 to rotate to move to each baking chamber 1, it can rotate within a limited shell space.

[0102] A movable guide member cooperating with the first movable member 331 and the second movable member 332 can be provided on the support plate 333 , and the movable guide member can be in the form of a track, a bolt and screw transmission mechanism, a belt transmission structure, or any other form that can drive the first movable member 331 and the second movable member 332 to move.

[0103] Specific to the present invention Fig.16 In the embodiment, the upper and lower surfaces of the support plate 333 are provided with slide rails respectively, the first moving member 331 and the second moving member 332 are sliders, the first moving member 331 can move along the upper slide rail, and the second moving member 332 can move along the lower slide rail.

[0104] The telescopic portion 33 further includes a telescopic driving member 334, which is connected to the support plate 333, and is used to drive the first moving member 331 and the second moving member 332 to move synchronously in a direction away from each other. Further, the telescopic driving member 334 is a belt transmission mechanism. The first moving member 331 and the second moving member 332 are respectively connected to belts on both sides of the pulley.

[0105] Furthermore, the rotating portion 32 is connected to the first moving member 331 so as to enable the rotating portion 32 to drive the telescopic portion 33 to move.

[0106] Furthermore, the moving part 31 includes an X-direction moving mechanism 311 and a Z-direction moving mechanism 312, the X-direction moving mechanism 311 includes an X-direction track and an X-direction driving assembly, the X-direction moving mechanism 311 can move back and forth on the X-direction track, the Z-direction moving mechanism 312 includes a Z-direction track and a Z-direction driving assembly, and the Z-direction moving mechanism 312 can move back and forth on the Z-direction track.

[0107] The second moving member 332 can move back and forth in the X direction. Due to the existence of the rotating part 32, the picking part of the telescopic part 33 can be driven to rotate in any direction, so the moving part 31 only needs to have an X-direction moving mechanism 311 and a Z-direction moving mechanism 312 to meet the use requirements. The X direction mentioned here refers to the left and right direction, and the Z direction refers to the up and down direction. The conveying assembly 3 of the present invention can drive the material tray to move in different directions through the mutual cooperation of the moving part 31, the rotating part 32 and the telescopic part 33, thereby smoothly realizing loading and unloading, and can be applied to different occasions.

[0108] Furthermore, fan blades are provided on the shell to dissipate the heat generated by the baking chamber 6 and prevent the external temperature of the baking device from being too high.

[0109] The left side of the baking device is provided with a loading platform, and the right side is provided with a unloading platform. The loading platform and the unloading platform can move back and forth in the Z direction, so that the telescopic part 33 can pick up the material tray.

[0110] The baking method of the baking device of the present invention comprises the following steps:

[0111] S1. The door assembly 2 is closed, the heating device 65 generates hot air, and enters each baking chamber 1 for preheating. After reaching the set temperature, the transport assembly 3 is started for loading;

[0112] S2. The transport assembly 3 moves to the loading platform, picks up the tray containing the lens to be baked on the loading platform, and then transports it to the baking chamber 1;

[0113] S3. The cylinder 93 drives the movable rod 94 to shorten, and the door assembly 2 rotates around the hinge with the first mounting seat 911 to open the door assembly 2;

[0114] Specifically, in step S3, when the door assembly 2 is opened, the spring member 18 loses the squeezing effect of the door assembly 2 and recovers, and pushes the sliding plate 13 to move forward, so that the second ventilation hole 12 and the first ventilation hole 11 are completely misaligned, and hot air cannot enter the baking chamber 1, thereby avoiding waste caused by the loss of hot air when the door is opened, and also avoiding a large amount of hot air gushing out to cause a load on the heating device 65 and affect the temperature of the hot air entering other baking chambers 1.

[0115] S4. The transport component 3 places the tray into the baking chamber 1, moves the transport component 3 to the unloading platform, picks up the empty tray on the unloading platform, and returns to the loading platform under the driving action of the X-direction moving mechanism 311;

[0116] S5. While the handling assembly 3 is moved to the unloading platform, the cylinder 93 drives the movable rod 94 to extend, and the door assembly 2 rotates around the hinge with the first mounting seat 911 to close the door assembly 2;

[0117] Specifically, in step S5, when the door assembly 2 is closed, it contacts and squeezes the sliding plate 13, and the sliding plate 13 moves backward, so that the second ventilation hole 12 and the first ventilation hole 11 are connected to form a channel, and hot air enters the baking chamber 1 through the channel to bake the lens.

[0118] S6. Return to step S2, execute the next cycle, and transport the tray containing the lens to be baked to the next baking chamber 1.

[0119] When the lens sent into the baking chamber 1 reaches the baking time, the transport assembly 3 moves to the front side of the corresponding baking chamber 1, the door assembly 2 automatically opens, and the transport assembly 3 takes out the baked lens and sends it to the next process.

[0120] Since the order of placing the lenses to be baked into different baking chambers 1 is different, the time to complete baking is also different. Therefore, the transport assembly 3 can be moved to the front side of different baking chambers 1 in sequence to realize the sequential removal of the baked lenses.

[0121] Furthermore, step S2 specifically includes the following steps:

[0122] S21. The loading platform is raised and lowered to the same height as the second movable member 332, the second movable member 332 passes through the outlet 101 and moves to the left limit position, the loading platform picks up the tray with the lens to be baked, the first movable member 331 moves to the right limit position, and the second movable member 332 drives the tray to retract;

[0123] S22. The rotating portion 32 is rotated 90° clockwise to ensure that the material tray is located directly in front of the baking chamber 6;

[0124] S23. The X-direction moving mechanism 311 and the Z-direction moving mechanism 312 work together to move the material tray to the front side of the baking chamber 1 where the material tray is to be placed.

[0125] Furthermore, step S4 specifically includes the following steps:

[0126] S41. The second movable member 332 extends backward, the material tray is placed in the baking chamber 1, and then the first movable member 331 moves backward to the limit position, and the second movable member 332 retracts forward;

[0127] S42. The rotating portion 32 rotates 90° clockwise, and the X-direction moving mechanism 311 and the Z-direction moving mechanism 312 work together to drive the transport assembly 3 to move to the unloading platform;

[0128] S43.X moves the moving mechanism 311 to drive the conveying assembly 3 back to the loading platform.

[0129] The baking device of the present invention is not limited to baking lenses, but can also be used to bake other precision components. Due to the high degree of automation, it can greatly save manpower and material resources, and it occupies a small area, which is conducive to the improvement of the production line.

[0130] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
