Description

Technical Field

[0001] The present invention relates to the technical field of firing process equipment, and in particular to a stacking plate equipment and a sintering production line. Background Art

[0002] Ceramic dielectric filters are widely used in filtering radio frequency signals due to their low loss, high dielectric constant, small frequency temperature coefficient and thermal expansion coefficient, and high power tolerance. With the advent of fifth-generation mobile networks (5G), the demand for ceramic dielectric filters is increasing.

[0003] Currently, the sintering process in pusher furnaces for filter firing relies on manual plate stacking, lamination, and loading and unloading. However, due to the small size of ceramic dielectric filters and the large production quantities required, manual plate stacking results in a high workload, high product scrap rates, and poor consistency, making it difficult to guarantee product quality and production capacity. Summary of the Invention

[0034] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0035] In the description of the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, "plurality" means at least two, for example, two, three, etc., unless otherwise clearly and specifically defined.

[0036] In this application, unless otherwise specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; they can refer to direct connection or indirect connection through an intermediate medium; they can refer to internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0037] In this application, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0038] On the first aspect, the embodiment of the present application first provides a code plate device, which is used for code plates when sintering, for example, ceramic dielectric filters. It can be understood that the code plate device provided in the embodiment of the present application can also be used as code plates for other items. The ceramic dielectric filter mentioned in the embodiment of the present application is only used as an exemplary description, and is not a limitation on its specific code plate object.

[0039] Reference Figure 1 and Figure 2 As shown, Figure 1 It is a schematic diagram of the overall structure of the code plate device provided in the embodiment of the present application. Figure 2 The present invention provides a stacking device according to an embodiment of the present invention, which includes a frame 10, a first transport mechanism 20, a second transport mechanism 30 and a stacking mechanism 40.

[0040] The frame 10 is the supporting skeleton of the entire device, and can be a structural frame welded from hard materials such as steel.

[0041] The first transport mechanism 20 and the second transport mechanism 30 are disposed side by side on the frame 10. The first transport mechanism 20 and the second transport mechanism 30 can be fixed to the frame 10 using screws, bolts, or the like, which facilitates removal and installation of the first transport mechanism 20 and the second transport mechanism 30. In some alternative embodiments, fixed hooks can be provided on the frame 10 to which the first transport mechanism 20 and the second transport mechanism 30 are attached, further facilitating removal and installation of the first transport mechanism 20 and the second transport mechanism 30.

[0042] The first transport mechanism 20 and the second transport mechanism 30 are respectively used to transport the sintering tray, wherein the sintering tray can be made of a high-temperature resistant material, such as a ceramic material.

[0043] Specifically, the first transport mechanism 20 and the second transport mechanism 30 can be transport mechanisms such as conveyor belts, transport rollers, transport rollers or transport rails. The target objects to be sintered (for example, green or cooked embryos of ceramic dielectric filters) can be placed on the sintering tray, so that the target objects to be sintered can be conveniently transported through the first transport mechanism 20 and the second transport mechanism 30.

[0044] The coding mechanism 40 includes a sliding assembly 41 and a grabbing assembly 42 arranged on the sliding assembly 41. The sliding assembly 41 is arranged above the first transport mechanism 20 and the second transport mechanism 30. The sliding assembly is used to drive the grabbing assembly to move between the first transport mechanism and the second transport mechanism; the grabbing assembly 42 is used to grab and transport the target object on the sintering tray, and, driven by the sliding assembly, code the target object to the sintering tray on another transport mechanism.

[0045] In the embodiment of the present application, a stacking mechanism 40 is arranged across the first transport mechanism 20 and the second transport mechanism 30. In this way, when the sintering tray carrying the ceramic green embryos to be sintered runs on the first transport mechanism 20, the stacking mechanism 40 places the green embryos on the first transport mechanism 20 onto the sintering tray on the second transport mechanism 30 through the grabbing component 42. This improves the stacking efficiency and the uniformity of the green embryos after stacking, ensures the firing quality, and avoids product defects caused by human factors.

[0046] Optional, see Figure 2 As shown, the sliding assembly 41 may be a sliding cylinder, specifically, it may include a slide rail 411 spanning the first transport mechanism 20 and the second transport mechanism 30, and a slider 412 disposed on the slide rail 411. The gripping assembly 42 is then disposed on the slider 412. The sliding of the slider 412 on the slide rail 411 drives the gripping assembly 42 to move on the first transport mechanism 20 and the second transport mechanism 30.

[0047] It should be noted that the sliding assembly 41 can also be some other type of sliding assembly. For example, a slide rail 411 is arranged above the first transport mechanism 20 and the second transport mechanism 30, and then a telescopic cylinder is arranged at either end of the slide rail to push the slider 412 to slide on the slide rail.

[0048] For another example, a lead screw may be installed above the first transport mechanism 20 and the second transport mechanism 30, and the slider 412 may be threadedly connected to the lead screw. The lead screw may be driven forward or reverse by a servo motor or a synchronous motor, thereby driving the movement of the slider 412.

[0049] It should be noted that the control of the sliding cylinder, telescopic cylinder, or servo motor can be performed using a control mechanism 80. The control mechanism 80 can be a programmable logic controller (PLC), a field-programmable gate array (FPGA), a microcontroller unit (MCU), or the like. The specific control method can refer to the control methods for the sintering temperature, air intake atmosphere, and timing of push plate sintering furnaces in the prior art. This will not be further described in the embodiments of the present application.

[0050] Optionally, the control mechanism 80 includes a display area 81 and a control area 82, and the control area 82 is electrically connected to the display area 81. The control area 82 and the display area 81 may be separate entities. For example, the display area 81 may be a monitor and the control area 82 may be an external keyboard. In some cases, the control area 82 and the display area 81 may also be integrated. For example, the control area 82 may be a virtual button displayed on the display area 81. Of course, the control area 82 may also be a physical button.

[0051] Optional, see Figure 3 As shown, Figure 3 yes Figure 2 A partial enlarged view of the center A. The grabbing assembly 42 includes a height adjusting member 421 and a grabbing member (not shown) disposed on the height adjusting member 421 .

[0052] The height adjustment member 421 may be a lifting motor or a lifting cylinder, and the gripping member may be a manipulator, such as a four-jaw chuck or a double-jaw chuck.

[0053] The height adjustment member 421 is provided on the sliding assembly 41 , and the height adjustment member 421 is used to adjust the distance between the grabbing member and the target object.

[0054] Specifically, the height adjustment member 421 may be provided on the slider 412 and move along with the slider 412. The gripping member is provided on the height adjustment member 421.

[0055] In this way, it is convenient to move the target on the first transport mechanism 20 to the sintering tray on the second transport mechanism 30 for stacking. Alternatively, the target on the second transport mechanism 30 can be moved to the sintering tray on the first transport mechanism 20.

[0056] Optionally, the gripping member includes a suction cup, and the gripping assembly 42 further includes a cylinder valve. The suction cup is connected to the height adjustment member 421 via the cylinder valve, and the cylinder valve is used to adjust the suction force of the suction cup.

[0057] In this way, the target object is grasped by the cooperation of the cylinder valve and the suction cup without applying clamping force to the target object, which ensures the integrity of the target object structure, thereby effectively ensuring the qualified rate and product quality of the sintered products.

[0058] In one possible implementation, the gripper may include multiple suction cups arranged side by side. These suction cups may be connected to a single cylinder valve, or each suction cup may be independently connected to a separate suction cup. This allows multiple suction cups to grasp an entire row of objects on the sintering tray at once, improving stacking efficiency. It is understood that the gripper may also be a single suction cup, grasping only one object on the sintering tray at a time.

[0059] Optional, see Figure 2As shown, the two code plate mechanisms 40 are provided side by side above the first transport mechanism 20 and the second transport mechanism 30 .

[0060] In some possible implementations, the two pick-up mechanisms 40 may not be arranged side by side. For example, they may be arranged above the first transport mechanism 20 and the second transport mechanism 30 at a certain angle. It is only necessary to ensure that the two pick-up mechanisms 40 can grab the target from the first transport mechanism 20 or the second transport mechanism 30 and place it on the other transport mechanism.

[0061] By providing two stacking mechanisms 40, one stacking mechanism 40 can move the green preforms from the first transport mechanism 20 onto an empty sintering tray on the second transport mechanism 30, while the other stacking mechanism 40 can move the cooked preforms from the second transport mechanism 30 onto an empty sintering tray on the first transport mechanism 20. In other words, the two stacking mechanisms 40 operate independently, ensuring continuous stacking between green and cooked preforms, effectively improving production efficiency and guaranteeing output.

[0062] Optionally, the first transport mechanism 20 and the second transport mechanism 30 may be arranged side by side on the frame 10 .

[0063] Further, refer to Figure 2 and Figure 3 As shown, in order to further improve the product qualification rate or product quality, in the embodiment of the present application, the code plate device also includes two visual inspection mechanisms 50, and the two visual inspection mechanisms 50 are respectively arranged on the two code plate mechanisms 40.

[0064] Specifically, in the embodiment of the present application, the visual inspection mechanism 50 can be a charge coupled device (CCD) image sensor. It is made of a highly sensitive semiconductor material and can convert light into electric charge, which is converted into a digital signal through an analog-to-digital converter chip. The digital signal is compressed and stored in the flash memory or built-in hard disk card inside the camera. Therefore, the data can be easily transmitted to the computer, and with the help of the computer's processing methods, the quality, placement, etc. of the product can be monitored. The CCD is composed of many photosensitive units, usually in units of millions of pixels. When the CCD surface is exposed to light, each photosensitive unit will reflect the charge on the component, and the signals generated by all the photosensitive units are added together to form a complete picture.

[0065] CCD visual inspection and positioning ensure that the gripper component accurately grasps the target object every time without causing damage. Furthermore, CCD visual inspection can monitor the quality of both raw and cooked dough, enabling quality control throughout the production process and timely removal of substandard products such as those with cracks or gaps, effectively ensuring product quality. Furthermore, CCD visual inspection ensures the accurate positioning of stacking plates, ensuring their neatness.

[0066] In some possible embodiments, the visual inspection mechanism 50 may also be a camera, which takes photos of the product and compares them with pre-stored photos in the control mechanism to perform positioning or inspect the quality of the product.

[0067] It is understood that the visual inspection mechanism 50 can be disposed on the sliding assembly 41, specifically on the slider 412. In this way, the visual inspection mechanism 50 moves along with the slider 412 and the gripping assembly 42, so that the relative position of the visual inspection mechanism 50 and the gripping assembly 42 remains unchanged, enabling more accurate positioning of the gripping assembly 42.

[0068] It should be noted that the visual inspection mechanism 50 may be fixed to the slider 412. For example, it may be fixed by screws, bolts, etc. In some possible embodiments, the slider 412 may be provided with a slot, and the visual inspection mechanism 50 may be plugged into the slider 412 through the slot.

[0069] Optional, see Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, Figure 4 yes Figure 2 A partial enlarged view of point B in the middle. Figure 5 This is a diagram of the internal structure of the stacking device provided in an embodiment of the present application. The stacking device also includes a loading and unloading mechanism 60, which is located on one side of the frame 10 and is arranged directly opposite the first transport mechanism 20. The loading and unloading mechanism 60 includes a lifting assembly 61, a magazine 62, and a tray pushing assembly 63.

[0070] The lifting assembly 61 is arranged on one side of the frame 10, and the magazine 62 is connected to the lifting assembly 61. The lifting assembly 61 is used to drive the magazine 62 to move up and down along the frame 10; the magazine 62 is used to place the sintering tray; the tray pushing assembly 63 is arranged on one side of the magazine 62, and the tray pushing assembly 63 is used to push the sintering tray in the magazine 62 onto the first transport mechanism 20.

[0071] Specifically, the lifting assembly 61 can be a lifting device such as a lifting cylinder or a lifting motor. The lifting rail of the lifting cylinder can be fixed to the side wall or side of the frame 10, for example, by screws, rods, or bolts. A support plate can be fixed to the lifting slide of the lifting cylinder, and the magazine 62 can be placed on the support plate. In this way, the lifting assembly 61 can drive the magazine 62 to move up and down.

[0072] The magazine 62 can be a box-like structure with openings on both sides, within which the sintering tray containing the target object is placed. When the magazine 62 reaches its lowest position, driven by the lifting assembly 61, it can dock with an automated guided vehicle (AGV) equipped with optical systems. This saves the cost of manually transporting the sintering trays, reduces labor, and improves production efficiency.

[0073] Optionally, the magazine 62 has a multi-layer chute 621 , and the sintering tray is inserted into the magazine 62 through the multi-layer chute 621 .

[0074] Optionally, the tray pushing assembly 63 can be a liftable sliding block, push rod or push plate; after the lifting assembly 61 transports the magazine 62 to the top, the tray pushing assembly 63 can push the sintering tray onto the first transport mechanism 20 from the bottom by relying on the friction between the bottom and the bottom of the sintering tray.

[0075] In some cases, the tray pushing assembly 63 may also be a robot, such as a double-jaw chuck, which grasps the end of the sintering tray and then pushes the sintering tray onto the first transport mechanism 20 .

[0076] Optional, see Figure 2 As shown, there may be two loading and unloading mechanisms 60 , and the two loading and unloading mechanisms 60 are respectively located at the two ends of the first transport mechanism 20 .

[0077] The two loading and unloading mechanisms 60 can be identical in structure. Specifically, one loading and unloading mechanism 60 primarily serves as the loading component, docking with the AGV and receiving sintering trays containing green preforms from the AGV. For example, the AGV dismounts and inserts the sintering trays into the magazine 62 through the chute 621 of the magazine 62. Insertion can be done one layer at a time, or multiple layers can be inserted. The other loading and unloading mechanism 60 primarily serves as the unloading component. Specifically, after the gripper assembly 42 places the cooked preforms from the second transport mechanism 30 onto the empty sintering tray on the first transport mechanism 20, the first transport mechanism 20 moves the cooked preforms on the sintering tray to the loading and unloading mechanism 60 and into the magazine 62. After being lowered to the lowest position by the lifting assembly, the preforms are transported away by the AGV. This reduces labor and improves both transportation and loading and unloading efficiency.

[0078] Optional, see Figure 6 As shown, Figure 6 yes Figure 1 The stacking device further comprises a stacking mechanism 70 , which is arranged on one side of the frame 10 and is opposite to the second transport mechanism 30 . The stacking mechanism 70 is used to stack the sintering pallets transported by the second transport mechanism 30 .

[0079] Specifically, the plate stacking mechanism 70 may be a robot, such as a four-jaw chuck or a double-jaw chuck, etc. The plate stacking mechanism 70 may be mounted on a side wall of the frame 10 .

[0080] In some cases, the stacking mechanism 70 can be installed separately from the frame 10. This separate installation allows the stacking mechanism 70 and the frame 10 to become two separate modules. If the stacking mechanism 70 fails, it can be replaced promptly or replaced directly with manual stacking, minimizing the impact on the production line.

[0081] Secondly, refer to Figure 7 As shown, Figure 7 : is a top view of the sintering production line provided in an embodiment of the present application, wherein: Figure 7 The direction indicated by the arrow in the figure represents the flow direction of the production line. This embodiment of the present application provides a sintering production line, comprising a push-plate sintering furnace (not shown) and a stacking device provided by any of the aforementioned optional embodiments. The stacking device's stacking mechanism 70 is further configured to place multi-layer sintering trays on a rotary track 100 of the push-plate sintering furnace and to place the sintering trays from the rotary track 100 onto a second transport mechanism 30.

[0082] Specifically, Figure 7 As an example, after the AGV trolley inserts the sintering tray into the magazine 62 (for example, Figure 7 The first transport mechanism 20 transports the sintering tray to the bottom of the stacking mechanism 40, and the grabbing assembly 42 grabs the green embryo on the sintering tray and stacks it on the empty sintering tray on the second transport mechanism 30, and then stacks the sintering tray on the first transport mechanism 20. Figure 7 The sintering tray is transported to the lower part of the furnace, and is stacked by the stacking mechanism (not shown in the figure). After stacking, the stacking mechanism moves to the left to the rotary track 100 and is pushed into the furnace by the push plate sintering furnace for calcination. After sintering is completed, the sintering tray is taken out of the rotary track 100 and is moved by the stacking mechanism to the second transport mechanism 30 ( Figure 7The preforms are transported upward on the second transport mechanism 30. After reaching the other end of the second transport mechanism 30, they are pushed back to the right second transport mechanism 30 by the rotary assist mechanism 90. On the right second transport mechanism 30, the grab assembly 42 moves the cooked preforms to the empty sintering trays on the first transport mechanism 20, freeing the sintering trays on the second transport mechanism 30. This circular, streamlined operation improves production efficiency.

[0083] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
