Description

Technical Field

[0001] The present invention relates to the field of vacuum pressing, and specifically to a vacuum pressing device for an aerogel silicone frame assembly. Background Art

[0002] The aerogel silicone frame is applied to the heat insulation and explosion prevention of power batteries. The processing process of the aerogel silicone frame assembly includes a series of fine steps. First, the silicone frame is fed into a gluing device, and uniform gluing treatment is carried out through this device. Subsequently, the aerogel is precisely pasted on the silicone frame to form a pre-pasted assembly. Next, this pre-pasted assembly needs to undergo a fusion process under high temperature and high pressure to ensure a firm bond between the aerogel and the silicone frame. However, in the current processing process, this key step is manually completed by workers, that is, the pre-pasted assembly is placed into a vacuum pressing device for processing.

[0003] This manual operation not only has safety hazards, because workers directly contact the equipment in a high temperature and high pressure environment and are easily injured such as scalded, but also has relatively low work efficiency. More importantly, manual operation is difficult to meet the needs of mass production, restricting the production capacity and efficiency of the production line. Therefore, we propose a vacuum pressing device for an aerogel silicone frame assembly to solve the above problems. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a vacuum pressing device for an aerogel silicone frame assembly.

[0005] A vacuum pressing device for an aerogel silicone frame assembly provided by the present invention includes a machine body. One end of the machine body is fixed with a column. The top of the column is rotatably connected with a rotary loading table through a one-way bearing. The rotary loading table is equiangularly installed with magazine-type bins. The machine body is equipped with a pressing workbench. The top of the machine body is fixed with a pressing hydraulic cylinder. The output end of the pressing hydraulic cylinder is fixed with an upper pressing plate that cooperates with the pressing workbench. The machine body is also equipped with a conveyor line and a loading / unloading device. The loading / unloading device is used to place the aerogel silicone frame assembly in the magazine-type bin into the pressing workbench and is also used to take out the pressed aerogel silicone frame assembly from the pressing workbench and place it on the conveyor line.

[0006] It should be emphasized that: The magazine-type bin includes a magazine-type bin for accommodating aerogel, and also has a magazine-type bin for accommodating the silicone frame. The magazine-type bin for accommodating aerogel and the magazine-type bin for accommodating the silicone frame are arranged alternately, and there are four magazine-type bins.

[0007] Preferably, a U-shaped groove is provided on the body. The bent part of the U-shaped groove has a right-angle transition, and the width of each part of the U-shaped groove is equal. The upper unloading device includes a slider slidably connected in the U-shaped groove and a motor fixed in the body. A fixed sleeve is fixed on the output shaft of the motor. One end of the fixed sleeve is embedded and slidably connected with an extension rod. The end of the extension rod is hinged to the slider. One end of the slider is fixed with a U-shaped frame. Feeding suction components and unloading suction components are installed at both ends of the U-shaped frame. A linkage component is installed between the U-shaped frame and the rotary feeding table.

[0008] Preferably, the linkage component includes a gear, a rack, and a vertical guide rod. A gear is fixed at the bottom of the rotary feeding table. A rack meshing with the gear is slidably connected to the body. One end of the rack is fixed with a vertical guide rod, and the vertical guide rod is slidably connected to the U-shaped frame.

[0009] Preferably, a self-locking ring is fixed at the bottom of the gear. The outer side wall of the self-locking ring is fixedly provided with limiting convex parts at equal angles. The limiting convex part includes a check plane and a guiding arc surface. An L-shaped plate is fixed on the side wall of the column. A positioning rod is slidably connected through the L-shaped plate. One end of the positioning rod is fixed with a T-shaped rod. A telescopic spring is sleeved outside the positioning rod. The end of the T-shaped rod cooperates with the guiding arc surface. One side wall of the T-shaped rod cooperates with the check plane.

[0010] Through the settings of the T-shaped rod, the telescopic spring, and the limiting convex part, it is avoided that the rotary feeding table rotates when being accidentally touched.

[0011] Preferably, the feeding suction component includes a feeding suction cup and a first guide rod fixed on the top of the feeding suction cup. The first guide rod is slidably connected to the U-shaped frame. A first anti-overpressure spring is sleeved outside the first guide rod. Both ends of the first anti-overpressure spring are fixedly connected to the U-shaped frame and the feeding suction cup respectively.

[0012] Preferably, the unloading suction component includes an unloading suction cup and a second guide rod fixed on the top of the unloading suction cup. The second guide rod is slidably connected to the U-shaped frame. A second anti-overpressure spring is sleeved outside the second guide rod. Both ends of the second anti-overpressure spring are fixedly connected to the U-shaped frame and the unloading suction cup respectively.

[0013] Preferably, when the feeding suction cup moves downward, the distance between the feeding suction cup and the unloading suction cup is equal to the distance between the feeding suction cup and the nearest magazine-type magazine.

[0014] Preferably, the magazine-type magazine includes a cylindrical body. A compression spring is fixed at the bottom of the cylindrical body. A pressing plate is fixed at the top of the compression spring. The pressing plate is slidably connected in the cylindrical body.

[0015] It should be emphasized that: the compression amount of the compression spring for carrying the aerogel is proportional to the number of aerogels, and the compression amount of the compression spring for carrying the silica gel frame is proportional to the number of silica gel frames, which is determined by the spring constant of the compression spring. Ensure that the topmost silica gel frame and aerogel are always within a specific height range (this range is very small because the deformation amounts generated by the self-stacking and extrusion of the aerogel and silica gel frame are limited).

[0016] Preferably, the side wall of the cylindrical bin body is provided with a notch.

[0017] Preferably, both the loading suction cup and the unloading suction cup are vacuum suction cups.

[0018] Usage process:

[0019] The motor drives the fixed sleeve and the extension rod to rotate together, prompting the slider to slide along the U-shaped groove. Since the bend of the U-shaped groove has a right-angle transition and the widths of all parts of the U-shaped groove are equal, during the sliding process of the slider, the U-shaped frame is always in a horizontal state. When the slider moves towards the clip-type magazine along the horizontal section of the U-shaped groove, the U-shaped frame drives the rack to move, and the rack drives the gear and the rotating loading table to rotate together. Due to the setting of the one-way bearing, every time the slider moves one cycle, the rotating loading table rotates by a ninety-degree angle. The loading suction cup first moves the silica gel frame in the clip-type magazine to the pressing workbench, and gluing is performed through the gluing equipment. Then the slider moves again, causing the rotating loading table to rotate by another ninety-degree angle. The aerogel is moved from the clip-type magazine to cover the silica gel frame through the loading suction cup. The upper pressing plate is driven by the pressing hydraulic cylinder to move downward, so that the upper pressing plate and the pressing workbench are combined together. The pressing workbench is provided with a vacuum pumping device and a heating device, and the aerogel and the silica gel frame are vacuum-pressed together through the vacuum pumping device and the heating device. Through the unloading suction cup, the pressed aerogel-silica gel frame assembly can be taken out of the pressing workbench and moved to the conveyor line.

[0020] Compared with the related technology, the present invention has the following beneficial effects:

[0021] Improve production efficiency

[0022] High degree of automation: The motor drives the slider to move along the U-shaped groove, and the precise rotation of the rotating loading table is realized by using the linkage component. The entire loading, unloading, and pressing processes are highly automated, reducing the need for manual intervention.

[0023] Quick material switching: Four clip-type magazines on the rotating loading table are alternately arranged to accommodate aerogels and silica gel frames, enabling rapid switching when operating different materials and improving the overall operating speed of the production line.

[0024] Relatively high safety

[0025] Workers do not need to come into contact with the pressing workbench. Description of the Drawings

Detailed Embodiments

[0033] The present invention will be further described below in conjunction with the drawings and embodiments.

[0034] Please refer to Figures 1 - Figure 6 , a vacuum pressing device for an aerogel silica gel frame assembly. The device mainly includes a body 1. One end of the body 1 is firmly fixed with a column 2, and the top of the column 2 is ingeniously connected with a rotatable rotating loading table 3 through a one-way bearing 41. On this rotating loading table 3, a plurality of magazine-type magazines 4 are installed at equal angles. These magazine-type magazines 4 are divided into two categories. One category is specifically used to accommodate aerogel, and the other is used to accommodate silica gel frames. The two types of magazines are arranged alternately to ensure convenient and efficient loading. A total of four magazine-type magazines 4 are provided to meet the production requirements.

[0035] A U-shaped groove 11 is also ingeniously designed on the body 1. The bending part of this U-shaped groove 11 adopts a right-angle transition design, and the width of each part thereof remains the same. Inside this U-shaped groove 11, a slider 12 is slidably connected, and the driving of the slider 12 comes from a motor 13 fixedly installed inside the body 1. The output shaft of the motor 13 is connected to a fixed sleeve 14, and one end of the fixed sleeve 14 is embedded and slidably connected with an extension rod 15, and the end of this extension rod 15 is hinged to the slider 12. When the motor 13 is started, it will drive the fixed sleeve 14 and the extension rod 15 to rotate together, thereby causing the slider 12 to slide along the U-shaped groove 11.

[0036] One end of the slider 12 is fixed with a U-shaped frame 16, and a loading suction component 17 and a unloading suction component 18 are respectively installed at both ends of this U-shaped frame 16. These two components are respectively responsible for placing the aerogel silica gel frame component in the magazine-type magazine 4 onto the pressing workbench 5, and taking out the pressed component from the pressing workbench 5 and placing it on the conveyor line 9. It is worth mentioning that a linkage component 19 is also installed between the U-shaped frame 16 and the rotary loading table 3 to ensure the coordinated movement between the two.

[0037] The specific structure of the linkage component 19 includes a gear 20 fixed to the bottom of the rotary loading table 3, and a rack 21 slidably connected to the body and meshed with the gear 20. One end of the rack 21 is fixed with a vertical guide rod 22, and this vertical guide rod 22 is also slidably connected with the U-shaped frame 16. When the slider 12 slides in the U-shaped groove 11, it will drive the rack 21 to move, thereby driving the gear 20 and the rotary loading table 3 to rotate together. Due to the setting of the one-way bearing 41, every time the slider 12 moves a cycle, the rotary loading table 3 will accurately rotate by a ninety-degree angle.

[0038] In order to ensure that the rotary loading table 3 will not rotate by itself when not affected by external forces, a self-locking mechanism is also designed. A self-locking ring 23 is fixed to the bottom of the gear 20, and a plurality of limiting convex parts 24 are fixed on the outer side wall of the self-locking ring 23 at equal angles. These limiting convex parts 24 include a check plane 25 and a guiding arc surface 26. An L-shaped plate 27 is fixed to the side wall of the column 2, and a positioning rod 28 is slidably connected through the L-shaped plate 27. One end of the positioning rod 28 is fixed with a T-shaped rod 29, and a telescopic spring 30 is also sleeved outside the positioning rod 28. When the rotary loading table 3 rotates to a specified position, the end of the T-shaped rod 29 will cooperate with the guiding arc surface 26, so that the T-shaped rod 29 is clamped into the check plane 25 under the action of the telescopic spring 30, thereby realizing the self-locking function.

[0039] Both the loading suction component 17 and the unloading suction component 18 adopt the design of vacuum suction cups, which respectively include a loading suction cup 31 and an unloading suction cup 34. These two suction cups are both slidably connected to the U-shaped frame 16 through guide rods, and an overpressure prevention spring is sleeved on the outside to ensure the smoothness of their movement. When the loading suction cup 31 is in the state of moving downward, the distance between it and the unloading suction cup 34 is exactly equal to the distance between the loading suction cup 31 and the nearest magazine-type magazine 4, and such a design can ensure the accuracy of loading and unloading.

[0040] The design of the magazine-type magazine 4 is also quite ingenious. It includes a cylindrical magazine body 37, and a compression spring 38 is fixed at the bottom of the magazine body. The top of the compression spring 38 is fixed with a pressure plate 39, and this pressure plate 39 can slide within the cylindrical magazine body 37. The compression amount of the compression spring 38 for carrying aerogels is proportional to the number of aerogels, and the compression amount of the compression spring 38 for carrying silicone frames is proportional to the number of silicone frames. Such a design can ensure that the topmost silicone frame and aerogel are always within a specific height range, thereby improving the accuracy and stability of loading. In addition, a notch 40 is provided on the side wall of the cylindrical magazine body 37 to facilitate the suction operation of the loading suction component 17 and the unloading suction component 18.

[0041] Summary of working principle

[0042] Rotary loading: The top of the column 2 is connected to the rotary loading table 3 through a one-way bearing 41, and four magazine-type magazines 4 are equiangularly installed thereon. These magazines are respectively used to accommodate aerogels and silicone frames, and are arranged alternately to facilitate automated picking and placing operations.

[0043] Magazine-type magazine design: Each magazine-type magazine 4 includes a cylindrical magazine body 37, with a compression spring 38 and a pressure plate 39 installed at the bottom. When placing materials, the compression spring 38 is compressed accordingly according to the quantity of the materials (aerogels or silicone frames), ensuring that the position of the topmost material is stable and within a specific height range, which is beneficial for subsequent precise picking and placing.

[0044] Automatic loading and unloading: The loading and unloading device 10 includes a slider 12, a motor 13, an extension rod 15 and a U-shaped frame 16, and is connected to the rotary loading table 3 through a linkage component 19. The motor 13 drives the fixed sleeve 14 and the extension rod 15, causing the slider 12 to slide along the U-shaped groove 11, thereby driving the U-shaped frame 16 to move. The loading suction component 17 and the unloading suction component 18 at both ends of the U-shaped frame 16 are respectively responsible for taking out the components from the magazine-type magazine 4 and placing them on the pressing base 5, and moving the pressed components to the conveyor line 9.

[0045] Precise control and overpressure prevention: The loading suction cup 31 and the unloading suction cup 34 are both vacuum suction cups, which are connected to the U-shaped frame 16 through the first guide rod 32 and the second guide rod 35, and are equipped with corresponding overpressure prevention springs (the first overpressure prevention spring 33 and the second overpressure prevention spring 36) to ensure appropriate pressure when sucking and releasing components and avoid damaging the components.

[0046] Linkage mechanism: The rotation of the rotating loading table 3 is realized by a linkage system composed of a gear 20, a rack 21 and a vertical guide rod 22. At the same time, through the cooperation of the self-locking ring 23 and its limiting convex part 24 with the positioning rod 28, the T-shaped rod 29 and the telescopic spring 30, precise positioning and self-locking functions are provided to ensure accurate rotation position each time.

[0047] Summary of the usage process

[0048] Through the operation of the motor 13, the slider 12 is urged to slide along the U-shaped groove 11, making the U-shaped frame 16 maintain a horizontal state.

[0049] When the slider 12 is located in the horizontal section of the U-shaped groove 11 and moves towards the magazine-type magazine 4, the U-shaped frame 16 drives the rack 21 to move, thereby driving the gear 20 and the rotating loading table 3 to rotate together to complete the selection and placement of materials.

[0050] Finally, the pressing hydraulic cylinder 6 performs vacuum pressing on the components located on the pressing base 5 through the upper pressing plate 7 to ensure tight combination between the components and improve product quality.

[0051] The above are only embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are similarly included in the patent protection scope of the present invention.
