Description

Technical Field

[0001] This utility model relates to baking equipment, and more particularly to an oven used in the production process of optical modules. Background Technology

[0002] In the production process of optical module products, ovens are mainly used for high-temperature baking, curing, drying and aging processes. Their function is to provide a stable temperature environment to promote material curing, remove moisture and improve the stability of product performance.

[0003] Currently, oven doors are primarily opened and closed manually. Operators open and close the oven door when placing optical module products into the oven to bake or removing baked products. This is mainly because the ovens used in optical module production are mostly general-purpose industrial ovens, whose original design primarily uses hinged doors. Compared to sliding or roller shutter doors, hinged doors offer better sealing and more precise temperature control. However, the opening angle of hinged doors is larger, making automation more difficult. Therefore, oven doors are currently still primarily opened manually. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the difficulty in achieving reliable automatic drive control of oven doors in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model provides an oven, comprising: The oven body has an opening on one side that extends inward to form a baking space; The door is hinged to the opening of the oven body; and, A drive assembly includes a drive member and a connecting rod. The drive member is mounted on an adjacent side of the oven body on the side with the opening. The connecting rod includes a first rod portion and a second rod portion connected to each other, forming a fixed angle between the first rod portion and the second rod portion. The first rod portion is hinged to the output end of the drive member, and the second rod portion is hinged to the door. The driving member drives the linkage to move, so that, under the structural limitation of a fixed included angle, the linkage applies a pulling or pushing force in an offset direction to the door body at the end of the linkage away from the driving member, thereby driving the door body to rotate and open / close.

[0006] In one embodiment of this utility model, when the driving member drives the door to close to the termination position, the second rod portion is approximately parallel to the opening plane covered by the door.

[0007] In one embodiment of this utility model, the fixed included angle is greater than 90°.

[0008] In one embodiment of this utility model, the fixed included angle is 110° to 130°.

[0009] In one embodiment of this utility model, the driving assembly further includes a first hinge seat and a second hinge seat, the driving member includes a linear driving member, the output end of the linear driving member is connected to the first rod portion through the first hinge seat; the second hinge seat is installed on the front of the door body, and the second rod portion is hinged to the door body through the second hinge seat.

[0010] In one embodiment of the present invention, a guide mechanism is further included, which is connected to the first hinge seat and is used to guide the first hinge seat to move along the moving direction of the linear drive member.

[0011] In one embodiment of the present invention, the guiding mechanism includes a guide rail and a slider. The guide rail is installed on an adjacent side of the oven body on the side with the opening and is arranged along the moving direction of the linear drive member. The slider can slide along the direction of the guide rail and is connected to the first hinge seat.

[0012] In one embodiment of the present invention, the drive assembly further includes a right-angle mounting plate, which includes a first mounting portion and a second mounting portion that are perpendicularly connected to each other. The first mounting portion is mounted on the front of the door, and the second mounting portion is located on the side adjacent to the front of the door. The second rod portion is connected to the first mounting portion so that the thrust of the connecting rod acting on the front of the door can be distributed to the side of the door during the transmission process.

[0013] In one embodiment of this utility model, the first rod portion and the second rod portion are integrally formed.

[0014] In one embodiment of this utility model, the door is hinged to the opening of the oven body via a hinge.

[0015] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial effects: This invention achieves automated opening and closing of an oven door through a mechanism consisting of a drive component and a connecting rod with a defined fixed angle. Specifically, the drive component is installed on an adjacent side of the oven body opening, and its output end is hinged to one end of the connecting rod. The connecting rod includes a first rod portion and a second rod portion connected to each other, forming a fixed angle between them. When the drive component drives the connecting rod to move, guided by the fixed angle, the connecting rod deflects during the movement, and applies a pulling or pushing force with a biased direction to the door at its end away from the drive component, thereby driving the door to rotate and achieving automatic opening and closing of the door.

[0016] When the drive component pushes the first rod, the second rod deflects in space due to the fixed angle. This causes the driving force, transmitted to the door via the connecting rod, to generate a greater rotational force in the eccentric direction, thereby improving the door's opening and closing efficiency. Simultaneously, in the later stages of door closure, the thrust exerted on the door at the connection point between the second rod and the door approaches perpendicular to the door's plane. This helps press the door tightly against the oven opening edge, improving the seal between the door and the oven, thus enhancing sealing performance and reducing heat loss.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0020] See Figures 1 to 4 As shown, this utility model embodiment provides an oven suitable for the baking and curing process of optical module products, including an oven body 10, a door 20 and a drive assembly 30.

[0021] The oven body 10 is a closed box structure with an opening 40 on one side facing the operator for loading and unloading materials. The opening 40 extends inward to form a heatable baking space 50, in which a support frame can be installed to support the optical module or other workpieces.

[0022] The door 20 is hinged to the opening 40 of the oven body. That is, the door 20 and the opening 40 of the oven body 10 are hinged, allowing the door 20 to rotate around the hinge axis, thus covering and opening the oven opening 40. The shape of the door 20 matches the opening 40, and their edge contours basically correspond to ensure a snug fit when closed.

[0023] The drive assembly 30 is mounted on the side of the oven body 10 adjacent to the side with the opening 40 and connected to the door 20. The drive assembly 30 includes a drive member 31 and a connecting rod 32. The drive member 31 is horizontally mounted on the side of the oven body 10 adjacent to the side with the opening 40. The connecting rod 32 consists of two rod portions, a first rod portion 321 and a second rod portion 322, which are connected to each other and form a fixed included angle α. The first rod portion 321 is hinged to the output end of the drive member 31. The second rod portion 322 is hinged to the door 20. The first rod portion 321 and the second rod portion 322 can be integrally formed, thereby simplifying the structure of the connecting rod 32 and increasing its strength.

[0024] This invention achieves automated opening and closing of the oven door 20 through a mechanism consisting of a drive member 31 and a connecting rod 32 with a fixed included angle α. Specifically, the drive member 31 is installed on an adjacent side of the oven body opening 40, and its output end is hinged to one end of the connecting rod 32. The connecting rod 32 includes a first rod portion 321 and a second rod portion 322 connected to each other, forming a fixed included angle α. When the drive member 31 drives the connecting rod 32 to move, the connecting rod 32 deflects during the movement due to the fixed included angle α and the hinged rotation of the door 20. That is, the end of the connecting rod 32 away from the drive member 31 rotates relative to the end closer to the drive member 31, thereby applying a pulling or pushing force with an offset direction to the door 20, thus driving the door 20 to rotate and achieving automatic opening and closing of the door 20.

[0025] When the drive member 31 pushes the first rod 321, due to the presence of the fixed included angle α, the second rod 322 deflects in space. This causes the driving force, when transmitted to the door 20 through the connecting rod 32, to generate a larger rotational force in the eccentric direction, thereby improving the opening and closing efficiency of the door 20. Simultaneously, in the later stages of door 20 closing, the thrust exerted on the door 20 at the connection point between the second rod 322 and the door 20 tends to be perpendicular to the plane of the door 20. This helps to press the door 20 tightly against the edge of the oven opening 40, improving the tightness of the fit between the door 20 and the oven, thus improving sealing performance and reducing heat loss.

[0026] In practical applications, the drive member 31 pushes the connecting rod 32 to move, causing the door 20 to gradually change from an open state to a closed state. When the drive member 31 drives the door 20 to close to the final position, the second rod portion 322 is approximately parallel to the plane of the opening 40 covered by the door 20.

[0027] By adopting the above design scheme, when the second rod 322 is close to the closing end point, its force direction tends to be perpendicular to the plane of the opening 40 covered by the door 20. Thus, when the door 20 is closed, it can generate a pressing force towards the oven body 10, so that the edge of the door 20 fits more tightly against the periphery of the oven opening 40, effectively improving the oven's sealing performance, reducing heat loss, and ensuring that the door 20 closes stably and reliably.

[0028] See Figures 3 to 4 As shown, the connecting rod 32 is formed by connecting the first rod part 321 and the second rod part 322, and the two form a fixed angle α. The angle of the fixed angle α is greater than 90°. Preferably, the angle of the fixed angle α is 110° to 130°.

[0029] Compared to a linear connecting rod 32, the obtuse-angled connecting rod 32 can generate a larger torque under the same drive stroke, improving the opening and closing efficiency of the door 20. It is particularly suitable for ovens with larger door sizes or a certain weight. In addition, an included angle greater than 90° also helps the connecting rod 32 move more smoothly and avoids interference between the connecting rod 32 and the corners of the oven body 10 during opening and closing.

[0030] Preferably, the included angle α is set to 110°–130°. This angle ensures effective transmission while facilitating the rational arrangement of the drive assembly 30 on the oven body. When the included angle is too small, the length of the connecting rod 32 needs to be increased accordingly to achieve sufficient opening and closing stroke of the door 20. This not only increases the overall structural size and occupies more space on the outside of the oven body, but may also lengthen the movement stroke of the drive component 31 and reduce its response speed, affecting the overall opening and closing efficiency. Setting the included angle to 110°–130° allows for a larger output lever arm within the limited length of the connecting rod 32, effectively shortening the stroke distance of the drive component 31. This makes the entire drive assembly 30 more compact, responds more quickly, and is easier to integrate into the oven side wall.

[0031] See Figures 1 to 4 As shown, the drive assembly 30 also includes a first hinge seat 33 and a second hinge seat 34. The drive member 31 is a linear drive member, such as an electric push rod or a cylinder, which has the characteristics of compact structure and smooth operation. The linear drive member is mounted on the mounting base plate 70 via the first mounting bracket 60, and the mounting base plate 70 is then mounted on the side of the oven body 10. The output end of the linear drive member is connected to the first rod portion 321 of the connecting rod 32 via the first hinge seat 33. The first hinge seat 33 is used to realize the rotational connection between the drive member 31 and the connecting rod 32, and guides the connecting rod 32 to adjust its angle during the operation of the drive member 31, so that the drive member 31 can drive the connecting rod 32 to rotate around the connection point when it is actuated. In practical applications, the drive member 31 can also use other types of drive mechanisms, so that when the connecting rod 32 is driven to move, the end of the connecting rod 32 away from the drive member 31 rotates relative to the end of the connecting rod 32 near the drive member 31, so as to achieve the purpose of opening and closing the door 20. This embodiment will not elaborate on this.

[0032] A second hinge seat 34 is provided on the front of the door body 20. The end of the second rod 322 is rotatably connected to the door body 20 through the second hinge seat 34. With the second hinge seat 34, the movement of the connecting rod 32 can directly act on the door body 20. During the linear movement of the driving member 31, the connecting rod 32 moves accordingly, and with the cooperation of a fixed included angle α, the driving force is transmitted to the door body 20 in an offset direction, thereby forming an effective opening and closing torque, driving the door body 20 to open and close around the rotation axis.

[0033] When the linear drive is activated, its output end extends or retracts in a straight line, causing the connecting rod 32, which is hinged to it, to move. Since a fixed angle α is provided between the first rod portion 321 and the second rod portion 322, during the process of the drive member 31 pushing the connecting rod 32, this fixed angle α causes the movement trajectory of the connecting rod 32 to undergo spatial deflection, allowing the driving force to be transmitted to the door body 20 in a suitable eccentric direction. This deflection effect creates a significant rotational torque during the pushing and pulling of the door body, enabling the door body 20 to rotate smoothly around its hinge axis.

[0034] When the door 20 is opened, the output end of the linear drive retracts inward, causing the connecting rod 32 to rotate. The end of the connecting rod 32 away from the door 20 applies a pulling force to the door 20, causing the door 20 to rotate outward from the closed state, thus realizing the opening operation. When the door 20 is closed, the output end of the linear drive extends outward, causing the connecting rod 32 to move towards the door 20. The driving force is transmitted to the door 20 through the connecting rod 32, pushing it to rotate from the open state to cover the opening 40 of the oven body 10. As the door 20 is about to close to the opening 40, the direction of the thrust applied at the connection between the second rod 322 and the door 20 gradually approaches the plane perpendicular to the opening of the door 20, effectively pressing the edge of the door 20 against the edge area of ​​the opening 40, thereby enhancing the fit and seal between the door 20 and the oven body 10, reducing heat loss, and ensuring a stable temperature in the baking space.

[0035] See Figures 1 to 4 As shown, the drive assembly 30 is also provided with a guide mechanism to limit the movement trajectory of the first hinge seat 33, so that it can move stably along the linear motion direction of the linear drive member, thereby avoiding shaking or deviation during the drive process.

[0036] Specifically, the guiding mechanism includes a guide rail 35 and a slider 36. The guide rail 35 is mounted on a mounting base 70 via a second mounting bracket 80. As described above, the mounting base 70 is mounted on the side adjacent to the side of the oven body 10 with the opening 40, and is arranged along the output direction of the linear drive member, thus aligning with the direction of motion of the drive member 31. The slider 36 can slide along the guide rail 35 and is fixedly connected to the first hinge seat 33. When the output end of the drive member 31 pushes the first hinge seat 33 to move, the slider 36 is guided within the guide rail 35, thereby ensuring that the linear motion path of the first hinge seat 33 does not deviate from the set trajectory.

[0037] See Figures 1 to 4 As shown, the drive assembly 30 also includes a right-angle mounting plate 37 for connecting the door body 20. This right-angle mounting plate 37 consists of a first mounting portion 371 and a second mounting portion 372 connected perpendicularly to each other, forming an overall L-shaped structure. The first mounting portion 371 is fixedly mounted on the front of the door body 20, while the second mounting portion 372 is closely attached to the adjacent side of the front of the door body 20.

[0038] The second rod portion 322 of the connecting rod 32 is connected to the first mounting portion 371 by a hinge, so that the driving force is first applied to the front of the door body 20. Since the right-angle mounting plate 37 has a right-angle structure, when the connecting rod 32 applies a pushing force to the front of the door body 20, the pushing force can be partially transmitted and distributed to the side of the door body 20 along the structural direction of the right-angle mounting plate 37. This not only reduces the concentrated stress on a single area of ​​the front of the door body 20, but also improves the uniformity of force and structural stability of the door body 20 during the opening and closing process, which is beneficial to improving the opening and closing reliability and service life of the oven door body 20.

[0039] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
