Description

Technical Field

[0001] This utility model relates to the field of glass processing technology, and in particular to a door component and processing device. Background Technology

[0002] As the applications of glass expand, the requirements for precision and quality in glass processing are also increasing. Some glass processing requires a vacuum environment, such as laminating and coating lines. During production, the glass needs to repeatedly enter and exit a vacuum chamber. The chamber is equipped with a door assembly and an opening. The opening connects to the vacuum chamber, and the door assembly covers the opening to isolate the chamber from the outside atmosphere, ensuring that the internal vacuum level meets the relevant requirements.

[0003] In related technologies, door components include a door body and a single connecting rod. The two ends of the connecting rod are rotatably connected to the door frame and the door body, respectively, to drive the door body to cover or move away from the opening, thereby realizing the opening and closing of the chamber. However, due to the large overall size of the door body (up to three meters in length), the connecting rod's pressure resistance on the door body is poor, making it easy for parts of the door body to not fit tightly against the door frame, resulting in air leakage in the chamber, that is, the door component has poor sealing performance.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] In related technologies, door components include a door body and a single connecting rod. The two ends of the connecting rod are rotatably connected to the door frame and the door body, respectively, to drive the door body to cover or move away from the opening, thereby realizing the opening and closing of the chamber. However, due to the large overall size of the door body (up to three meters in length), the connecting rod's pressure resistance on the door body is poor, making it easy for parts of the door body to not fit tightly against the door frame, resulting in air leakage in the chamber, that is, the sealing performance of the door component is poor.

[0041] In view of this, the first aspect of this utility model provides a door assembly 10 that can ensure sealing performance. Referring below... Figure 1 and Figure 2 The following describes a door assembly 10 according to an embodiment of this application. Specifically, the door assembly 10 includes a door body 100 and a connecting rod assembly 200.

[0042] Reference Figure 1The door 100 is used to cover the opening 201 of the door frame 20 to achieve a seal. In some embodiments, the door frame 20 can be a door frame 20 on a glass processing apparatus. In other embodiments, the door frame 20 can also be a door frame 20 on other equipment. In other embodiments, the door frame 20 can also be a door frame 20 on a wall. This application embodiment uses the door frame 20 of a glass processing apparatus as an example for illustration.

[0043] Reference Figure 1 and Figure 2 The linkage assembly 200 is used to drive the door body 100 to open and close relative to the door frame 20. The linkage assembly 200 connects the door body 100. Specifically, the linkage assembly 200 includes a first drive rod 210 and a second drive rod 220 connected to each other. In some embodiments, the structure of the first drive rod 210 may be the same as that of the second drive rod 220. In other embodiments, the structure of the first drive rod 210 may be different from that of the second drive rod 220. This application embodiment illustrates the example of the first drive rod 210 and the second drive rod 220 having different structures. Refer to... Figure 2 In terms of orientation, the first drive rod 210 can be a drive rod on the upper side of the linkage assembly 200, and the second drive rod 220 can be a drive rod on the lower side of the linkage assembly 200.

[0044] It should be noted that in some embodiments, the first drive rod 210 and the second drive rod 220 may share a power source. In other embodiments, the first drive rod 210 and the second drive rod 220 may use different power sources. This application embodiment uses the example of the first drive rod 210 and the second drive rod 220 sharing a power source for illustration. It can be understood that the power source of the door assembly 10 may be a motor, a cylinder, or a hydraulic cylinder, etc.

[0045] Reference Figure 1 and Figure 2 Both the first drive rod 210 and the second drive rod 220 are rotatably connected to the door frame 20. In some embodiments, the first drive rod 210 and the second drive rod 220 may be rotatably connected to the same position on the door frame 20. In other embodiments, the first drive rod 210 and the second drive rod 220 may also be rotatably connected to different positions on the door frame 20. This application embodiment uses the example of the first drive rod 210 and the second drive rod 220 being rotatably connected to different positions on the door frame 20 for illustration.

[0046] It should be noted that the rotation axis of the first drive rod 210 is parallel to the rotation axis of the second drive rod 220, as shown in the reference. Figure 1In terms of orientation, the rotation axis of the first drive rod 210 can be arranged to extend in the front-back direction, and the rotation axis of the second drive rod 220 can also be arranged to extend in the front-back direction. The first drive rod 210 and the second drive rod 220 can jointly drive the door body 100 to move towards the door frame 20, thereby covering the opening 201 to achieve a seal.

[0047] In the technical solution of this utility model, the door assembly 10 includes a door body 100 and a connecting rod assembly 200. The door body 100 is adapted to cover the opening 201 of the door frame 20. The connecting rod assembly 200 connects the door body 100. The connecting rod assembly 200 includes a first driving rod 210 and a second driving rod 220 connected to each other. Both the first driving rod 210 and the second driving rod 220 are rotatably connected to the door frame 20. The rotation axis of the first driving rod 210 is parallel to the rotation axis of the second driving rod 220. In the prior art, the door assembly includes a door body and a single connecting rod, with both ends of the connecting rod rotatably connected to the door frame and the door body respectively, so as to drive the door body to cover or move away from the opening, thereby realizing the opening and closing of the chamber. However, due to the large overall size of the door (up to three meters in length), the connecting rods exert poor force on the door, making it easy for parts of the door to not fit tightly against the door frame, resulting in air leakage in the chamber. In this solution, the first drive rod 210 and the second drive rod 220 can jointly drive the door 100 toward the door frame 20, thereby covering the opening 201. That is, this solution has multiple drive rods to drive the door 100, which can effectively increase the pressure exerted by the door 100 on the door frame 20, reduce the situation where the door 100 is not tightly fitted to the door frame 20, ensure the sealing of the door assembly 10, and improve the stability of the opening and closing of the door 100.

[0048] The specific opening and closing settings of the door 100 are described below. In some embodiments, the door 100 has a first state and a second state. (Refer to...) Figure 1 In the first state, the door 100 abuts against the door frame 20 and covers the opening 201, meaning the door 100 can achieve a closed seal on the opening 201. (Refer to...) Figure 2 In the second state, the door 100 is at least partially spaced from the door frame 20, meaning that the door 100 can release the opening 201.

[0049] Both the first drive rod 210 and the second drive rod 220 are capable of rotating relative to the door frame 20 to drive the door body 100 to switch between a first state and a second state. (Refer to...) Figure 2 In terms of orientation, the first drive rod 210 and the second drive rod 220 can rotate counterclockwise to switch the door 100 from the second state to the first state; the first drive rod 210 and the second drive rod 220 can rotate clockwise to switch the door 100 from the first state to the second state. In this design, the first drive rod 210 and the second drive rod 220 drive the door 100 to open and close by rotation, making the overall operation convenient and quick.

[0050] It should be noted that in some embodiments, the door assembly 10 includes a third drive rod, which can work together with the first drive rod 210 and the second drive rod 220 to drive the door body 100 to rotate and achieve opening and closing. The structure of the third drive rod can be the same as that of the first drive rod 210, and the third drive rod can share a power source with the first drive rod 210. The specific configuration of the third drive rod can be determined according to the actual situation. The third drive rod of this solution can further increase the pressure exerted by the door body 100 on the door frame 20, reduce the situation where the door body 100 is not tightly fitted to the door frame 20 in some areas, and improve the sealing performance of the door assembly 10.

[0051] The specific configuration of the linkage assembly 200 is described below. In some embodiments, the linkage assembly 200 includes a connecting rod 300. The connecting rod 300 includes a first end 310 and a second end 320 arranged opposite to each other along its extension direction, as shown in Figure 1. Figure 1 In terms of orientation, the first end 310 can be the upper end of the connecting rod 300, and the second end 320 can be the lower end of the connecting rod 300. It should be noted that the first end 310 can be rotatably connected to the first driving rod 210, and the second end 320 can be rotatably connected to the second driving rod 220. The connecting rod 300 in this design enables the first driving rod 210 and the second driving rod 220 to jointly drive the door body 100, ensuring the reliability of the door body 100's rotational opening and closing. Furthermore, compared to a solution where a single connecting rod drives the door body's opening and closing, this design results in a smaller volume occupied by the door assembly 10 along the thickness direction of the door frame 20 when the door body 100 is open. This avoids the situation where the opening and closing range of the door body 100 is limited by external space, increasing the application range of the door assembly 10.

[0052] Reference Figure 1 and Figure 2 In some embodiments, when the door 100 is in the first state (closed state), the arrangement direction of the first drive rod 210 is inclined relative to the door frame 20, which increases the pressure applied to the door 100 by the first drive rod 210, thereby increasing the resistance force applied by the door 100 to the door frame 20 and ensuring the sealing performance of the door assembly 10. In other embodiments, when the door 100 is in the first state (closed state), the arrangement direction of the second drive rod 220 is inclined relative to the door frame 20, which increases the pressure applied to the door 100 by the second drive rod 220, thereby increasing the resistance force applied by the door 100 to the door frame 20 and ensuring the sealing performance of the door assembly 10. In other embodiments, when the door 100 is in the first state (closed state), the arrangement direction of the connecting rod 300 is inclined relative to the door frame 20, which increases the pressure applied to the door 100 by the connecting rod 300, thereby increasing the resistance force applied by the door 100 to the door frame 20 and ensuring the sealing performance of the door assembly 10. The specific configuration of the linkage assembly 200 can be determined according to the actual situation.

[0053] Reference Figure 1 and Figure 2 In some embodiments, the door assembly 10 includes a positioning rod 400. The positioning rod 400 is connected to the connecting rod 300. When the door body 100 is in a first state (closed state), the positioning rod 400 can abut against the door frame 20 to prevent the door body 100 from excessively pressing against the door frame 20. That is, the positioning rod 400 can prevent the door body 100 from excessively pressing against the door frame 20, which could cause the door frame 20 to deform, thereby extending the service life of the door assembly 10.

[0054] Reference Figure 1 and Figure 2 The specific configuration of the positioning rod 400 is described below. In some embodiments, when the door 100 is in a first state (closed state), the positioning rod 400 has a first position and a second position relative to the door frame 20. When the positioning rod 400 is in the first position, there is a first distance between the positioning rod 400 and the door frame 20; when the positioning rod 400 is in the second position, there is a second distance between the positioning rod 400 and the door frame 20. The second distance is greater than the first distance, meaning there are multiple distances between the positioning rod 400 and the door frame 20. Therefore, the positioning rod 400 can limit the door 100 from applying multiple resistance forces of different magnitudes to the door frame 20, meeting the sealing requirements of different scenarios.

[0055] The specific positioning configuration of the positioning rod 400 relative to the door body 100 is described below. In some embodiments, the positioning rod 400 is rotatably connected to the connecting rod 300. Specifically, the rotation axis of the positioning rod 400 is arranged intersecting the rotation axis of the first drive rod 210. It can be understood that in some embodiments, the rotation axis of the positioning rod 400 may be perpendicular to the rotation axis of the first drive rod 210. In other embodiments, the rotation axis of the positioning rod 400 may be at other angles that are not perpendicular to the rotation axis of the first drive rod 210. This application embodiment is described with the rotation axis of the positioning rod 400 being perpendicular to the rotation axis of the first drive rod 210. The positioning rod 400 can rotate relative to the connecting rod 300 to switch between a first position and a second position. Further, the positioning rod 400 can be a screw, which can be threadedly connected to the threaded hole of the connecting rod 300. The adjustment operation of the positioning rod 400 in this solution is convenient and quick, and can adapt to various pressure adjustment needs.

[0056] Reference Figure 1 and Figure 2 The following describes the pressure adjustment setting of the door body 100 against the door frame 20. In some embodiments, the first drive rod 210 is located on the side of the second drive rod 220 opposite to the opening 201, referring to... Figure 1In terms of orientation, the second drive rod 220 is located above the opening 201, and the first drive rod 210 is located above the second drive rod 220. The door body 100 can be connected to the second drive rod 220. The door assembly 10 includes an adjustment part 500, which is connected to the door body 100. The adjustment part 500 can adjust the pressure exerted by the door body 100 on the door frame 20, which can prevent the door body 100 from exerting too much pressure on the door frame 20 and causing deformation of the door frame 20, and can also prevent the door body 100 from exerting too little pressure on the door frame 20 and causing the door frame 20 to be loosely connected.

[0057] In some embodiments, the adjusting part 500 can be an adjusting screw. By driving the adjusting screw to rotate, the pressure exerted by the door body 100 on the door frame 20 can be adjusted. It is understood that the adjusting part 500 can adjust the pressure exerted by a part of the door body 100 on the door frame 20, or it can adjust the pressure exerted by the entire door body 100 on the door frame 20. It should be noted that when the adjusting part 500 can adjust the pressure exerted by a part of the door body 100 on the door frame 20, multiple adjusting parts 500 can be configured. Multiple adjusting parts 500 can adaptively adjust the pressure exerted by different areas of the door body 100 on the door frame 20. The specific configuration of the adjusting part 500 can be determined according to the actual situation. The adjusting part 500 of this solution can adjust the door body 100. When the door assembly 10 is applied to processing equipment, it can quickly handle abnormal situations in the equipment, reducing cost losses caused by downtime.

[0058] Reference Figure 1 and Figure 2 In some embodiments, the door assembly 10 includes a sealing portion 600, which may be disposed between the door body 100 and the door frame 20. The sealing portion 600 is arranged at least partially around the opening 201. Specifically, the sealing portion 600 may be arranged partially around the opening 201 or may be arranged around the opening 201. This embodiment of the application will be described using the sealing portion 600 surrounding the opening 201 as an example. During the process of the door body 100 pressing against the door frame 20, the sealing portion 600 can undergo elastic deformation, which can prevent the door body 100 and the door frame 20 from colliding and can also improve the sealing performance of the door assembly 10. Further, the sealing portion 600 can be a sealing ring or other elastic element, and the specific arrangement of the sealing portion 600 can be determined according to the actual situation. It should be noted that when the door assembly 10 includes both a sealing ring and an adjustment part 500, the adjustment part 500 can adjust the pressure applied by the door body 100 to the door frame 20, which can ensure that there is no air leakage while making the deformation of the sealing ring moderate, thereby extending the replacement cycle of the sealing ring on the sealed door and saving labor and material costs.

[0059] Reference Figure 1 and Figure 2The specific rotational arrangement of the first drive rod 210 and the door frame 20 is described below. In some embodiments, the door assembly 10 includes a first base 700. One end of the first base 700 is fixedly connected to the door frame 20, and the other end is rotatably connected to the end of the first drive rod 210 opposite to the connecting rod 300, that is, the first drive rod 210 can rotate relative to the first base 700 to drive the door 100 to open and close. The first base 700 in this solution can increase the arrangement distance of the first drive rod 210 relative to the door frame 20, prevent the first drive rod 210 from interfering during rotation, and ensure the smoothness and stability of the door 100 opening and closing.

[0060] Reference Figure 1 and Figure 2 The specific rotational arrangement of the second drive rod 220 and the door frame 20 is described below. In some embodiments, the door assembly 10 includes a second base 800. One end of the second base 800 is fixedly connected to the door frame 20, and the other end is rotatably connected to the end of the second drive rod 220 opposite to the connecting rod 300, that is, the second drive rod 220 can rotate relative to the second base 800 to drive the door 100 to open and close. The second base 800 in this solution can increase the arrangement distance of the second drive rod 220 relative to the door frame 20, prevent the second drive rod 220 from interfering during rotation, and ensure the smoothness and stability of the door 100 opening and closing.

[0061] A second aspect of this utility model provides a processing apparatus for processing glass. The processing apparatus includes a door assembly 10 and a base as described in the above embodiment. Specifically, the base can define a cavity. A door frame 20 is provided on at least one side of the base, and the door frame 20 can be located on any side of the base in the transverse direction. The door frame 20 has an opening 201 communicating with the cavity, which is suitable for accommodating glass. It is understood that the glass can enter and exit the cavity through the opening 201, and the door assembly 10 can open and close the opening 201. This processing apparatus can effectively increase the pressure exerted by the door 100 on the door frame 20, reduce the possibility of the door 100 not fitting tightly against the door frame 20 in certain areas, ensure the sealing performance of the door assembly 10, and improve the processing quality of the glass.

[0062] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0063] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or," "and / or," or "and / or" throughout the text implies three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where A and B are simultaneously satisfied. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
