Description

Technical Field

[0001] The present invention relates to the technical field of pressing devices, and in particular to a composite plate pressing device. Background Art

[0002] With the rapid development of the Internet of Things, artificial intelligence and automated control technologies, smart home systems are undergoing a profound transformation from the intelligence of single devices to the integration of the entire house. Modern smart home facilities have placed higher requirements on the performance of building materials, especially in terms of structural strength, electromagnetic compatibility, thermal stability, etc., which need to meet the special working conditions of smart equipment. Therefore, the structural support components of current smart home facilities are generally made of composite panels.

[0003] The processing of composite boards mainly relies on hot pressing composite technology, and its core processes include two key links: gluing and pressing. However, there are still certain deficiencies in the existing technology in actual production. The traditional manual gluing method has problems such as uneven thickness of the glue layer and low coating efficiency, which is difficult to meet the mass production needs of smart home products. Especially when processing special composite boards with electromagnetic shielding layers, manual gluing can easily cause local accumulation of conductive glue, resulting in a decrease in electromagnetic shielding effectiveness. Even if some manufacturers have set up automatic gluing systems, their automated production lines use glue machines that are separated from hot presses. The boards will be exposed to an open environment for a period of time during the transfer process. Combined with the fact that the bonding surface is prone to adsorbing environmental dust during the transfer, it will directly affect the wettability of the glue, and then affect the bonding effect between the various composite layers in the composite board. Therefore, the present application provides a composite board pressing device to meet the needs. Summary of the Invention

The drive shaft of the servo motor extends into the groove on the guide rail and is fixedly connected to a gear, and the teeth of the gear and the guide teeth are adapted to each other.

[0009] Optionally, a limiting groove that matches the shape of the limiting plate is opened on the top of the guide rail, and the bottom end of the limiting plate is in an inverted T shape and is sleeved in the limiting groove.

[0010] Optionally, the mounting assembly includes a second fixing frame fixedly connected to the first fixing frame, the two ends of the glue coating tube are fixedly connected to the second fixing frame, a connecting port is provided in the middle of the top end of the glue coating tube, and a first through opening is opened in the middle of the top end of the top plate.

[0011] Optionally, a multi-stage electric push rod is sleeved on the inner side of the second fixed frame, and a piston is sleeved on the end of the movable part of the multi-stage electric push rod. The two ends of the glue coating tube are open, the piston is inside the glue coating tube, and the piston is adapted to the shape of the inner wall of the glue coating tube.

[0012] Optionally, the scraper assembly includes a slide fixedly connected to the outer end of the first fixed frame below, the bottom of the slide is rotatably connected to evenly distributed rollers, and a base plate is fixedly connected between the two slides, the bottom end of the base plate is fixedly connected to symmetrically distributed scrapers, the two ends of the base plate are fixedly connected to the slide, and a second through opening corresponding to the position of the glue coating tube is also opened at the bottom of the base plate, and an S-shaped deformation zone is provided at the connection between the base plate and the slide.

[0013] Optionally, the glue blocking assembly includes symmetrically distributed side panels arranged on the top of the bottom plate, and a top plate is connected to the top ends of the two side plates. The top plate surrounds the top outer side of the glue coating tube, and the top plate, side plates and bottom plate are detachably connected together.

[0014] Optionally, the top plate is arc-shaped, and a second connecting strip is provided at the bottom of both ends of the top plate, a second connecting port that is adapted to the shape of the second connecting strip is opened at the top end of the side plate, and the bottom end of the side plate is fixedly connected to the first connecting strip, and a first connecting port that is adapted to the shape of the first connecting strip is opened on the bottom plate.

[0015] Optionally, a cavity is opened on one side of the side panel facing the middle of the top panel, and evenly distributed inclined plates are arranged in the cavity, and a closing plate is fixedly connected to the outside of the bottom end of the cavity, and the end of the inclined plate is inclined upward, dividing the cavity in the side panel into multiple separated chambers.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, by setting up guide rails and drive components, after the gluing operation is completed, the glue tube can be detached from the bottom of the upper pressing platform in time, which will not affect the subsequent pressing process of the upper and lower pressing platforms. After the gluing operation is completed, new plates can be added immediately and pressed, which greatly reduces the time interval between the gluing step and the pressing step, avoids the glue from being exposed to the open environment for a long time, is not easy to absorb environmental dust, prevents affecting the wettability of the glue, and effectively improves the bonding effect between the composite layers in the composite plate.

[0018] By setting up an installation component and a multi-stage electric push rod, the installation component maintains the synchronous movement between the glue coating tube and the drive component, and relies on the multi-stage electric push rod to adjust the width value that the glue sprayed from the glue coating tube can cover. Combined with the start and stop of the glue supply system and the displacement of the glue coating tube under the upper pressing table, the length value that the glue sprayed from the glue coating tube can cover can be controlled to adapt to the processing requirements of composite panels of different sizes and improve the overall adaptability range of the device.

[0019] By setting up a scraper assembly, the glue coating tube moves under the upper pressing platform under the action of the servo motor and sprays glue. At the same time, the scraper contacts the glue on the plate and follows the movement of the glue coating tube to scrape the glue on the plate evenly, thereby avoiding local accumulation of conductive glue and preventing the electromagnetic shielding performance of the composite plate from decreasing after forming.

[0020] By setting the deformation zone and inclined surface in the scraper assembly, the setting of the deformation zone not only controls the contact effect between the scraper and the surface of the plate, ensuring the uniform scraping of the glue, but also avoids excessive pressure on the plate and causing damage to the plate. The setting of the inclined surface can increase the contact area between the scraper and the glue when performing the scraping operation, thereby further improving the uniform scraping effect of the glue.

[0021] By setting up a glue blocking component, during the gluing process, it is wrapped around the outside of the area where the glue is sprayed by the glue coating tube to prevent the glue from being sprayed outside the plate and causing pollution to the entire device. When the glue coating tube moves to an area perpendicular to the upper and lower press platforms, the dripping residual glue is collected to further avoid pollution to the upper and lower press platforms, and it can also prevent the dripping glue from causing uneven distribution of glue on the plate after the glue scraping operation.

[0042] like Figures 1 to 2As shown, an embodiment of the present invention provides a composite plate pressing device, including a pressing frame 1, in which an upper pressing platform 2 and a lower pressing platform 3 are equipped. The lower pressing platform 3 is fixedly installed at the bottom position of the pressing frame 1, and the upper pressing platform 2 is movably sleeved on the inner side of the pressing frame 1 through a hydraulic lifting structure. The position of the upper pressing platform 2 corresponds to the position of the lower pressing platform 3. A heating module is provided in the upper pressing platform 2 and the lower pressing platform 3 for heating the composite plate during the pressing process to realize hot pressing and compounding of the plate. The principles and usage process of the above-mentioned upper pressing platform 2 and the lower pressing platform 3 and the heating module are the same as those in the prior art and will not be elaborated here.

[0043] In this embodiment, if Figures 1 to 5 As shown, the front and rear sides of the upper pressing platform 2 are fixedly connected with symmetrically distributed guide rails 4 through metal plates, and a servo motor 5 is arranged on the outside of the guide rail 4. The upper and lower ends of the servo motor 5 are fixedly connected with a first fixing frame 6, and the end of the upper first fixing frame 6 is fixedly connected to the limit plate 18, and the end of the lower first fixing frame 6 is fixedly connected to the slide 14, and the outside of the lower first fixing frame 6 is fixedly connected to the second fixing frame 7, the second fixing frame 7 and the bottom of the first fixing frame 6 are perpendicular to each other, and the end of the second fixing frame 7 extends to the bottom of the upper pressing platform 2, and a glue coating tube 16 is fixedly connected between the second fixing frames 7. The guide rail 4 is U-shaped as a whole, and a groove is provided on the outside of the guide rail 4 close to the position of the servo motor 5, and evenly distributed guide teeth 11 are provided on the inner side wall of the bottom end of the groove. The driving shaft of the motor 5 extends into the groove on the guide rail 4 and is fixedly connected to the gear 12. The teeth of the gear 12 are adapted to the guide teeth 11. A limiting groove 13 adapted to the shape of the limiting plate 18 is opened on the top of the guide rail 4. The bottom end of the limiting plate 18 is in an inverted T shape and is sleeved in the limiting groove 13. When relative displacement occurs between the servo motor 5 and the first fixed frame 6 and the guide rail 4, it can provide guidance and limitation for the movement of the servo motor 5 and the first fixed frame 6. When the servo motor 5 is working, it can drive the gear 12 to rotate through its driving shaft, and then through the meshing rotation between the teeth on the gear 12 and the guide teeth 11, drive the servo motor 5 as a whole to slide on the outside of the guide rail 4 along the guidance of the limiting plate 18 and the limiting groove 13, and then drive the glue coating tube 16 to displace at the bottom of the upper pressing table 2.

[0044] In this embodiment, if Figures 3 to 5As shown, a connecting port 17 is provided at the middle of the top of the glue coating tube 16, and the connecting port 17 is used to connect with the glue supply system. The glue used for plate compounding can be input into the glue coating tube 16 through the connecting port 17 through the pipeline, the glue storage container, and the delivery pump. A first through opening 15 is provided at the middle of the top of the top plate 8 for exposing the connecting port 17 to facilitate the connection between the connecting port 17 and the glue supply system. The bottom of the glue coating tube 16 is provided with evenly distributed nozzles, which can evenly spray the glue entering the glue coating tube 16 and apply it to the outside of the plate to be compounded. The glue coating tube 16 is positioned along the U-shaped structure of the guide rail 4 under the action of the servo motor 5. The glue tube 16 moves so that when following the servo motor 5 to the two end positions of the guide rail 4, it leaves the bottom area of ​​the upper pressing platform 2, so that after the gluing operation is completed, it is promptly detached from the bottom of the upper pressing platform 2, which will not affect the subsequent pressing process of the upper pressing platform 2 and the lower pressing platform 3. As a result, after the gluing operation is completed between the upper pressing platform 2 and the lower pressing platform 3, new panels can be added immediately and pressed, which greatly reduces the time interval between the gluing step and the pressing step, avoids the glue from being exposed to the open environment for a long time, is not easy to absorb environmental dust, prevents the wettability of the glue from being affected, and effectively improves the bonding effect between the composite layers in the composite panel.

[0045] In this embodiment, if Figures 3 to 6 as well as Figure 11 As shown, a multi-stage electric push rod 19 is sleeved on the inner side of the second fixing frame 7, and a piston 22 is sleeved on the end of the movable part of the multi-stage electric push rod 19. The two ends of the glue coating tube 16 are open. Since the multi-stage electric push rod 19 and the second fixing frame 7 are symmetrically distributed on both sides of the glue coating tube 16, the two pistons 22 can be inserted into the interior of the glue coating tube 16 from the open ends of the glue coating tube 16, and the shape of the piston 22 is adapted to the shape of the inner side wall of the glue coating tube 16. When the specifications of the plate to be compounded between the upper pressing platform 2 and the lower pressing platform 3 change, the multi-stage electric push rod 19 can drive the piston 22 to move in the glue coating tube 16 through the expansion and contraction of its movable part. The internal displacement of the glue coating tube 16 isolates the nozzles outside the two pistons 22 and allows the glue to be sprayed only from the nozzles between the two pistons 22 when the glue supply system delivers glue. This adjusts the width of the glue sprayed from the glue coating tube 16 that can be covered. Combined with the start and stop of the glue supply system and the displacement of the glue coating tube 16 below the upper pressing table 2, the length of the glue sprayed from the glue coating tube 16 that can be covered can be controlled to meet the processing requirements of composite panels of different sizes, so that the glue sprayed from the glue coating tube 16 can completely cover the position of the panel, ensuring uniform spraying of the glue on the panel.

[0046] In this embodiment, if Figures 5 to 8As shown, the bottom of the slide 14 is rotatably connected to rollers that are evenly distributed, and a bottom plate 10 is fixedly connected between the two slides 14. The top of the bottom plate 10 is provided with symmetrically distributed side plates 9. The top ends of the two side plates 9 are connected to a top plate 8. The top plate 8 surrounds the top outside of the glue coating tube 16. The two ends of the bottom plate 10 are fixedly connected to the slide 14, and a second through opening 25 corresponding to the position of the glue coating tube 16 is also provided at the bottom of the bottom plate 10. The glue sprayed by the nozzle of the glue coating tube 16 can pass through the second through opening 25 to act on the sheet material waiting for hot pressing and compounding. The top plate 8, side plate 9 and bottom plate 10 are detachable. They are connected together to form a whole in the connected state, surrounding the outside of the glue coating tube 16, and can be wrapped around the outside of the area where the glue is sprayed by the glue coating tube 16, so as to control the scope of action of the glue sprayed by the glue coating tube 16, and avoid the glue being sprayed outside the plate to cause pollution to the entire device. The bottom end of the base plate 10 is fixedly connected with symmetrically distributed scrapers 21. The glue coating tube 16 moves under the upper pressing table 2 under the action of the servo motor 5 and sprays glue. At the same time, the scraper 21 contacts the glue on the plate, and follows the movement of the glue coating tube 16 to further scrape the glue on the plate, thereby avoiding local accumulation of conductive glue. , to prevent the electromagnetic shielding efficiency of the composite plate from decreasing after forming, a deformation zone 20 with an S-shaped bend is provided at the connection between the bottom plate 10 and the slide 14. The thickness value at the deformation zone 20 is less than the thickness value of other areas on the bottom plate 10, and the strength is weaker. It is more likely to deform after being subjected to external force. After the bottom plate 10 follows the downward pressure of the upper press table 2 and the guide rail 4 and contacts the surface of the composite plate, the bottom plate 10 can bend and deform at the deformation zone 20 after receiving the reaction force of the plate, which not only controls the contact effect of the scraper 21 with the surface of the plate, ensures that the glue is scraped evenly, but also avoids excessive pressure on the plate to cause the plate to bend. In order to prevent the material from being damaged and not being acted upon by external forces, the roller at the bottom end of the slide 14 is above the bottom end of the scraper 21. When the scraper 21 follows the descent of the upper pressing platform 2 and contacts the plate and causes the deformation zone 20 to bend and deform, the roller in the slide 14 contacts the edge position of the top of the lower pressing platform 3, thereby providing auxiliary support to the slide 14 in the process of the bottom plate 10 following the displacement of the servo motor 5 and the glue coating tube 16, thereby enhancing the stability of the bottom plate 10 during the displacement process. The bottom end of the scraper 21 is provided with a slope 26, which can increase the contact area between the scraper 21 and the glue when performing the scraping operation, thereby further improving the glue scraping effect.

[0047] In this embodiment, if Figures 7 to 10As shown, the top plate 8 is arc-shaped, and the bottom of both ends thereof is provided with a second connecting strip 27, the top end of the side plate 9 is provided with a second connecting port 28 adapted to the shape of the second connecting strip 27, and the bottom end of the side plate 9 is fixedly connected with the first connecting strip 23, and the bottom plate 10 is provided with a first connecting port 24 adapted to the shape of the first connecting strip 23. The top plate 8, the side plate 9 and the bottom plate 10 are detachably connected through the second connecting strip 27 and the second connecting port 28 as well as the first connecting strip 23 and the first connecting port 24. The second connecting strip 27 and the first connecting strip 23 are both made of hard rubber, which has good deformation ability while taking into account a certain strength, so that the top plate 8, the side plate 9 and the bottom plate 10 can be plugged and unplugged, and the stability after connection can be ensured. A cavity is provided on the side of the side plate 9 facing the middle of the top plate 8, and a uniformly distributed cavity is provided in the cavity. The inclined plate 29 of the cloth, and the outer side of the bottom end of the cavity is fixedly connected with a closing plate 30, the end of the inclined plate 29 is inclined upward, dividing the cavity in the side plate 9 into a plurality of separated chambers, and the setting of the closing plate 30 also makes the side plate 9 in a vertical state, and the internal inclined plate 29 and the area where the closing plate 30 is located at the bottom can form a storage space for glue, and then when the glue coating tube 16 is sprayed and moved from the area parallel to the guide rail 4 and the upper and lower pressing platforms 2 and 3 to the area perpendicular to each other, the dripping residual glue is collected, further avoiding contamination of the upper and lower pressing platforms 2 and 3, and also avoiding the dripping glue from causing the glue on the plate to be unevenly distributed again after the scraping operation is completed. The detachable connection between the top plate 8, the side plate 9 and the bottom plate 10 also makes the side plate 9 quickly disassembled and replaced after long-term use, and reused after cleaning.

[0048] The present invention encompasses any alternatives, modifications, equivalents, and solutions that fall within the spirit and scope of the present invention. To provide a thorough understanding of the present invention, specific details are described in detail below in connection with the preferred embodiments of the present invention, but those skilled in the art will be able to fully understand the present invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of the present invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
