Description

Technical Field

[0001] This utility model relates to the field of getter activation technology, and in particular to a strip-shaped getter activation device for vacuum glass. Background Technology

[0002] To maintain the vacuum level of the vacuum chamber in vacuum glass over a long period, a getter is placed inside the chamber during manufacturing to absorb any remaining gas and any subsequently released gases. The getter must be activated after being placed in the vacuum chamber to function properly. This activation is typically achieved by heating the getter with a heater.

[0003] The getter commonly used in existing vacuum glass is in the form of a disc. The activation device usually involves installing a heat source on an activation platform. The vacuum glass is placed on the activation platform and the position of the getter is aligned with the heat source. After heating for a period of time, the getter can be activated by heating.

[0004] The aforementioned activation device is designed for disc-shaped getters. Disc-shaped getters have a small area, requiring a small heating area from the heater; the heating range of a single heater is sufficient to cover the disc-shaped getter. Therefore, activating the disc-shaped getter can be achieved by aligning the heater with the disc-shaped getter and heating it to the activation temperature for a sufficient time. However, for strip-shaped getters (also known as "strip getters"), due to their longer length, there is currently no heater with a heating area sufficient to cover the entire strip-shaped getter; therefore, there are no activation devices for strip-shaped getters currently on the market. Utility Model Content

[0005] To address the problems existing in the prior art, namely that existing getter activation devices cannot activate strip-shaped getters, the purpose of this invention is to provide a strip-shaped getter activation device for vacuum glass. By setting a long strip-shaped heating head, and ensuring that the effective heating area of ​​the heating head can spatially cover the strip-shaped getter, the device can achieve heating activation of the strip-shaped getter.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A strip-shaped getter activation device for vacuum glass, wherein a strip-shaped getter is disposed inside the vacuum glass, characterized in that it includes a heater, the heater including a heating head, the heating head being elongated and the effective heating area of ​​the heating head being spatially capable of covering the strip-shaped getter.

[0008] The present invention is further configured to include a conveying mechanism for carrying and conveying vacuum glass.

[0009] The present invention is further configured such that: the conveying mechanism is a horizontal conveying mechanism, and the vacuum glass is in a horizontal state on the horizontal conveying mechanism.

[0010] The present invention is further configured such that: the horizontal conveying mechanism includes a longitudinal conveying component, which is used to drive the vacuum glass to move longitudinally.

[0011] The present invention is further configured such that: the horizontal conveying mechanism further includes a transverse conveying component and a lifting component, the transverse conveying component is used to drive the vacuum glass to move laterally, and the lifting component is used to drive the transverse conveying component to be lower or higher than the longitudinal conveying component in the vertical direction.

[0012] The present invention is further configured to include a temperature sensor, which is used to detect the temperature of the strip-shaped getter.

[0013] The present invention is further configured to include a controller and an alarm, wherein the controller controls the alarm to sound an alarm based on the temperature measured by the temperature sensor.

[0014] The present invention is further configured such that: the conveying mechanism is a vertical conveying mechanism, and the vacuum glass is in a vertically inclined state on the vertical conveying mechanism.

[0015] The present invention is further configured such that: the vertical conveying mechanism includes a vertical plate and a bottom conveying component arranged in a vertically inclined state; the vacuum glass abuts against the vertical plate and is parallel to the plane of the vertical plate; the bottom conveying component is located at the bottom of the vertical plate; the vacuum glass is located on the bottom conveying component; and the bottom conveying component carries and conveys the vacuum glass.

[0016] The present invention is further configured to include a pressing mechanism for pressing the vacuum glass against the conveying mechanism. The pressing mechanism includes a pressing member and a pressing drive. The pressing member and the pressing drive are connected. The pressing drive can drive the pressing member to press against or move away from the vacuum glass in a direction perpendicular to the surface of the vacuum glass. The length direction of the pressing member is consistent with the length direction of the strip getter.

[0017] In summary, the beneficial effects achieved by this utility model are as follows:

[0018] (1) The effective heating area of ​​the long strip heating head can cover the strip getter in space, thus completing the heating and activation of the strip getter;

[0019] (2) The clamping mechanism can provide pressure to the vacuum glass to ensure the flatness of the vacuum glass in the length direction of the strip getter, thereby ensuring that the distance between the strip getter and the heating head in its length direction remains consistent and ensuring the heating effect.

Therefore, they should not be construed as limitations on this application.

[0031] It should be noted that the embodiments and features involved in the embodiments of this utility model can be combined with each other without conflict. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0032] Example 1

[0033] As attached Figure 1-3 As shown, a strip-shaped getter activation device for vacuum glass includes a conveying mechanism, a heater 2, and a pressing mechanism 4. Existing vacuum glass 7 has a strip-shaped getter (not shown) disposed within its vacuum cavity. The getter is typically located near one edge within the vacuum cavity, and its length direction aligns with the length direction of the edge of the vacuum glass 7.

[0034] Appendix Figure 3 The dashed line represents the vacuum glass 7. A conveying mechanism is used to carry and transport the vacuum glass 7, and the conveying direction of the vacuum glass 7 is consistent with the length direction of the strip-shaped getter inside the vacuum glass 7. In this embodiment, a horizontal conveying mechanism 1 is used, and the vacuum glass 7 is in a horizontal state on the horizontal conveying mechanism 1.

[0035] The horizontal conveying mechanism 1 includes a longitudinal conveying component 101, a transverse conveying component 102, and a lifting component 103.

[0036] The longitudinal conveying assembly 101 is used to drive the vacuum glass 7 to move longitudinally. In this embodiment, longitudinal refers to the length direction of the strip getter, i.e., the attached... Figure 1 Or attached Figure 3 The longitudinal conveying assembly 101 includes multiple rollers, each roller having a length direction of approximately [missing information]. Figure 2 Or attached Figure 3 The f-direction is perpendicular to the g-direction. Multiple roller conveyors are arranged parallel to each other at intervals along the g-direction. The drive connection method of the multiple roller conveyors will not be described in detail here.

[0037] The transverse conveying assembly 102 is used to convey the vacuum glass 7 transversely. In this embodiment, transverse is the direction perpendicular to the length of the strip getter, i.e., attached... Figure 2 Or attached Figure 3 The transverse conveying assembly 102 includes multiple synchronous belts, each positioned between two adjacent rollers of the longitudinal conveying assembly 101, with the multiple synchronous belts arranged parallel and spaced apart along the g direction. The specific structural form and driving method of the synchronous belts will not be described further.

[0038] The lifting assembly 103 is connected to the transverse conveyor assembly 102 and is used to drive the transverse conveyor assembly 102 to move vertically. The lifting assembly 103 includes a lifting drive motor and a lifting connector. The lifting drive motor is located below the transverse conveyor assembly 102, and the lifting connector is connected to all synchronous belts. The lifting drive motor drives the transverse conveyor assembly 102 to move vertically through the lifting connector, so that the top surface of the synchronous belt of the transverse conveyor assembly 102 is lower than or higher than the top surface of the roller conveyor of the longitudinal conveyor assembly 101. When the transverse conveyor assembly 102 is lower than the longitudinal conveyor assembly 101 in the vertical direction, the transverse conveyor assembly 102 does not contact the vacuum glass 7, and the vacuum glass 7 is driven by the longitudinal conveyor assembly 101; when the transverse conveyor assembly 102 is higher than the longitudinal conveyor assembly 101 in the vertical direction, the longitudinal conveyor assembly 101 does not contact the vacuum glass 7, and the vacuum glass 7 is driven by the transverse conveyor assembly 102.

[0039] Heater 2 is a device in the prior art capable of heating and activating the getter. It can be a non-contact, high-efficiency heater such as a high-frequency induction heater, an ultra-high-frequency induction heater, a microwave heater, or a laser heater. In this embodiment, there is one heater 2. In other embodiments, two heaters, three heaters, or any number of heaters can be provided.

[0040] The heater 2 is equipped with a heating head 201 at its end, as shown in the attached figure. Figure 4 As shown, the heating head 201 is elongated, and its length direction is aligned with the length direction of the strip-shaped getter. The effective heating area of ​​the heating head 201 can spatially cover the strip-shaped getter, allowing it to be heated to the required activation temperature.

[0041] As attached Figure 1-3 As shown, the clamping mechanism 4 includes a clamping member 401 and a clamping drive (not shown in the figure). The clamping member 401 and the clamping drive are connected; the specific drive connection method will not be described in detail here. In this embodiment, the clamping member 401 is located above the vacuum glass 7, and the clamping drive can drive the clamping member 401 to move vertically up and down, that is, to move in a direction perpendicular to the surface of the vacuum glass 7. When the clamping member 401 presses vertically downwards against the vacuum glass 7, it can press the vacuum glass 7 onto the horizontal conveying mechanism 1.

[0042] The clamping member 401 is elongated, with its length direction aligned with the length direction of the strip-shaped getter (i.e., the g direction). The clamping member 401 is positioned in the f direction on the horizontal conveying mechanism 1 near the heating head 201, thereby ensuring the flatness of the vacuum glass 7 along the length direction of the strip-shaped getter and maintaining a stable distance between the strip-shaped getter and the heating head 201, thus ensuring the heating effect of the heating head 201. Preferably, the clamping member 401 and the heating head 201 are offset laterally to avoid affecting the normal operation of the heating head 201.

[0043] In this embodiment, the clamping member 401 is a clamping rod, and the length direction of the clamping rod is arranged along the length direction (i.e., the g direction) of the strip-shaped getter. The lower surface of the clamping rod can be made of rubber, polyurethane, silicone, nylon, or other soft composite materials. Soft composite materials have high wear resistance and can prevent scratching the glass surface. In other embodiments, the clamping member 401 can be configured as multiple clamping heads arranged along the length direction of the strip-shaped getter, that is, the length direction of the clamping member 401 composed of multiple clamping heads is consistent with the length direction of the strip-shaped getter. The material of the clamping heads can also be a soft composite material.

[0044] The activation device also includes a temperature sensor 5, a controller, and an alarm.

[0045] Temperature sensor 5 is used to detect the temperature of the strip-shaped getter. In this embodiment, temperature sensor 5 is positioned above the heating head 201. There can be one or more temperature sensors 5. Temperature sensor 5 is electrically connected to the controller, transmitting the temperature information of the strip-shaped getter to the controller. The controller can control the heating power and on / off state of heater 2 based on the temperature information from temperature sensor 5. The controller is also electrically connected to an alarm, controlling the alarm to sound based on the temperature information from temperature sensor 5. For example, if the temperature measured by temperature sensor 5 consistently fails to reach the activation temperature of the getter within the activation time or consistently exceeds the activation temperature of the getter, the controller will activate the alarm.

[0046] The positioning element 3 positions the vacuum glass 7 so that the strip-shaped getter inside the vacuum glass 7 can be aligned with the heating head 201. When the strip-shaped getter is aligned with the heating head 201, the effective heating area of ​​the heating head 201 spatially covers the strip-shaped getter. The positioning element 3 can be a long strip-shaped positioning element, and the length direction of the long strip-shaped positioning element is parallel to the length direction of the strip-shaped getter; the positioning element 3 can also be composed of multiple positioning wheels, and all positioning wheels are arranged at intervals along the length direction of the strip-shaped getter.

[0047] The positioning element 3 is higher in the vertical direction than the longitudinal conveying assembly 101 and the transverse conveying assembly 102, so that the vacuum glass 7 located on the longitudinal conveying assembly 101 or the transverse conveying assembly 102 can contact the positioning element 3. When one edge of the vacuum glass 7 on which the strip of getter is provided is in complete contact with the positioning element 3, the position of the heating head 201 can be perfectly aligned with the strip of getter inside the vacuum glass 7.

[0048] The implementation principle of the above embodiments is as follows:

[0049] The longitudinal conveying assembly 101 conveys the vacuum glass 7 longitudinally (g direction) and stops conveying after the vacuum glass 7 is in place. Driven by the lifting assembly 103, the transverse conveying assembly 102 rises until the top surface of the synchronous belt is higher than the top surface of the roller conveyor, thereby lifting the vacuum glass 7 away from the longitudinal conveying assembly 101. The transverse conveying assembly 102 then moves to convey the vacuum glass 7 along the f direction, ensuring that the edge of the vacuum glass 7 with the strip-shaped getter is in complete contact with the positioning member 3. Then, driven by the lifting assembly 103, the transverse conveying assembly 102 descends vertically, causing the vacuum glass 7 to fall onto the longitudinal conveying assembly 101. The pressing mechanism 4 actuates, causing the pressing member 401 to press against the upper surface of the vacuum glass 7, thus ensuring the flatness of the vacuum glass 7 in the g direction and maintaining a consistent distance between the strip-shaped getter and the heating head 201 along its length. Subsequently, heater 2 operates, and heating head 201 heats the strip-shaped getter to the activation temperature and maintains it for a certain period of time. The heating time of the strip-shaped getter is not less than the activation time of the strip-shaped getter, thereby realizing the activation of the strip-shaped getter.

[0050] Example 2

[0051] As attached Figure 5 As shown, this utility model discloses a strip-shaped getter activation device for vacuum glass. Unlike Embodiment 1, the horizontal conveying mechanism 1 only includes the longitudinal conveying component 101 and does not include the transverse conveying component 102 and the lifting component 103. (See attached diagram) Figure 5 The dashed line represents the vacuum glass 7. During the transport along the g direction, the edge of the vacuum glass 7 remains in complete contact with the positioning member 3, thus eliminating the need for the transverse transport assembly 102 to move the vacuum glass 7 along the f direction. Furthermore, in this embodiment, the positioning member 3 is preferably a positioning wheel to reduce friction with the vacuum glass 7.

[0052] In some other embodiments, the longitudinal conveying assembly 101 can be replaced by a conveyor belt instead of a roller conveyor, and the length direction of the conveyor belt is aligned with the g-direction. In this implementation, the edge of the vacuum glass 7 also remains in full contact with the positioning member 3, thus eliminating the need for a transverse conveying assembly 102.

[0053] Example 3

[0054] As attached Figure 6 As shown, this utility model discloses a strip-shaped getter activation device for vacuum glass. Unlike Embodiment 2, each roller in the longitudinal conveying assembly 101 is inclined at a certain angle relative to the f direction. This angle is greater than 0° and less than 30°, thereby causing the vacuum glass 7 to automatically move towards the positioning member 3 during conveying. (See attached image) Figure 6 The dashed line represents vacuum glass 7.

[0055] Example 4

[0056] As attached Figure 7-8 As shown, this utility model discloses a strip-shaped getter activation device for vacuum glass. Unlike Embodiment 1, the conveying mechanism is a vertical conveying mechanism 6, and the vacuum glass 7 is vertically inclined on the vertical conveying mechanism 6. (Attached) Figure 8 The dashed line represents vacuum glass 7.

[0057] The vertical conveying mechanism 6 includes a vertical plate 601, a roller 602, and a bottom conveying component 603.

[0058] The upright plate 601 is set in a vertically inclined state, that is, the upright plate 601 is tilted at a certain angle relative to the vertical direction. The bottom conveyor 603 is located at the bottom of the upright plate 601, and the vacuum glass 7 is located on the bottom conveyor 603. The bottom conveyor 603 carries and conveys the vacuum glass 7 along the g direction. The bottom conveyor 603 can be a synchronous belt or a roller, and its specific structure and driving method will not be described in detail here.

[0059] The vacuum glass 7 rests against the vertical plate 601 and is parallel to the plane of the vertical plate 601, so that the vacuum glass 7 always maintains a vertical tilt during the transportation process to ensure the stability of the transportation.

[0060] The upright plate 601 has multiple rows of holes, and each hole is fitted with a freely rotating support wheel 602. During the transport of the vacuum glass 7, the support wheel 602 can provide support for the vacuum glass 7 and reduce the friction between the vacuum glass 7 and the upright plate 601.

[0061] Specifically, the upright plate 601 can be a single, integral plate or composed of multiple perpendicularly intersecting beams. When the upright plate 601 is a single, integral plate, its lower part is provided with an elongated hole extending along the conveying direction of the vacuum glass 7, and the heating head 201 of the heater 2 is aligned with the elongated hole to allow energy from the heater 2 to pass through. When the upright plate 601 is composed of multiple perpendicularly intersecting beams, the holes for mounting the guide wheels 602 are located on the crossbeams along the conveying direction of the vacuum glass 7, and the heating head 201 of the heater 2 is offset vertically from the crossbeams to allow energy from the heater 2 to pass through.

[0062] In this embodiment, the pressing mechanism 4 is used to press the vacuum glass 7 against the upright plate 601. Specifically, the pressing member 401 and the pressing drive 402 are both disposed on the side of the vacuum glass 7 away from the upright plate 601. The pressing drive 402 can drive the pressing member 401 to press against or move away from the vacuum glass 7 in a direction perpendicular to the surface of the vacuum glass 7.

[0063] The clamping member 401 is positioned higher than the heating head 201, thus offsetting it vertically from the heating head 201 to avoid affecting the heating head 201's heating and activation of the strip getter.

[0064] The position of the clamping element 401 corresponds to the position of the two rows or one row of rollers 602 at the bottom of the upright plate 601, so that both sides of the vacuum glass 7 are supported, so as to ensure that the vacuum glass 7 can be clamped and to protect the vacuum glass 7 from being damaged during the clamping process.

[0065] Example 5

[0066] This embodiment differs from Embodiment 1 in that it eliminates the conveying mechanism and instead uses a support platform. The support platform carries the vacuum glass 7. The vacuum glass 7 is placed on the support platform manually or using a robotic arm or other means, and the strip-shaped getter inside the vacuum glass 7 is aligned with the heating head 201. This ensures that the effective heating area of ​​the heating head 201 spatially covers the strip-shaped getter. The heating head 201 then operates, heating the strip-shaped getter. After activation, the vacuum glass 7 is moved to the next workstation manually or using a robotic arm or other means.

[0067] Those skilled in the art will understand from the technical solution of this utility model that, in actual production, the length of the strip-shaped getter is not necessarily a strict straight line, and its positional distribution along its length is not necessarily strictly parallel to the edges of the vacuum glass. However, the heating area of ​​the heating head can cover the width of the strip-shaped getter, thus enabling the strip-shaped getter to be used. Therefore, the description of the length direction of the strip-shaped getter in this application includes both the actual situations of the getter itself and its positional distribution. Similarly, the fact that the length direction of the clamping member is consistent with the length direction of the strip-shaped getter does not mean that they need to be strictly identical; it is sufficient that the clamping member can ensure the flatness of the vacuum glass along the length direction of the strip-shaped getter.

[0068] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including both the preferred embodiments and all changes and modifications falling within the scope of the present invention. Clearly, those skilled in the art can make various alterations and modifications to the present invention without departing from its spirit and scope. Thus, if these modifications and modifications of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include these modifications and modifications.
