Description

Technical Field

[0001] The invention relates to the field of feeding devices, in particular to a double-group aerogel silica gel frame circulating feeding device. Background Art

[0002] Power batteries generally use a composite structure of aerogel insulation pads and silicone frames to achieve thermal runaway protection between battery cells. Some use an integrated aerogel-silicone frame design to extend the thermal runaway propagation time between battery cells to more than 30 minutes. The aerogel-silicone frame material composite process includes the following three steps:

[0003] Aerogel preforming: aerogel powder is mixed with a binder and formed into a thin sheet (thickness 0.1-2mm) by molding or casting.

[0004] Silicone frame injection molding: Liquid silicone (LSR) or high temperature vulcanized silicone (HTV) injection molding is used, and the surface is designed with microstructure (roughness Ra 0.8-1.6μm).

[0005] Hot pressing packaging: The aerogel sheet is embedded in the groove of the silicone frame and composited by vacuum hot pressing.

[0006] When pressing the aerogel and silicone frame, they need to be placed one by one on the pressing workbench for pressing. After the pressing is completed, the pressed products are removed and loaded again. Generally, a clip-type hopper is used for loading. However, after the product in a single clip-type hopper is used up, the pressing operation needs to be stopped and the aerogel or silicone frame needs to be added to the clip-type hopper again.

[0007] Therefore, a double-group aerogel silica gel frame circulating feeding device is proposed to solve the above problems. Summary of the Invention

[0008] In order to solve the above technical problems, the present invention provides a double-group aerogel silica gel frame circulating feeding device, comprising an aerogel feeding workbench and a silica gel frame feeding workbench, a pressing workbench is installed between the aerogel feeding workbench and the silica gel frame feeding workbench, an X-axis and Z-axis driving module are installed on the pressing workbench, and a pneumatic suction cup for sucking aerogel and silica gel frame is installed on the output end of the X-axis and Z-axis driving module. The aerogel feeding workbench and the silica gel frame feeding workbench both include,

[0009] A base, wherein a motor is embedded and fixedly mounted inside the base, and an output shaft of the motor passes through the top of the base;

[0010] A sleeve is fixedly connected to the output shaft of the motor, and a mounting groove is provided on the top of the sleeve;

[0011] A rotating shaft is placed in the mounting groove at the top of the sleeve;

[0014] The baffle is fixedly connected to the top of the base, and the baffle cooperates with the slide rod.

[0015] Preferably, it also includes a limiting device installed on the base, which is used to limit the one-way rotation of the rotary worktable. The limiting device includes a one-way bearing, the inner ring of the one-way bearing is fixedly connected to the side wall of the rotary worktable, and the outer ring is connected to a fixing ring. The bottom of the fixing ring is symmetrically fixedly connected to a connecting rod, and the connecting rod is slidably connected to the base.

[0016] Preferably, the base is symmetrically provided with mounting holes running through it from top to bottom, and the connecting rod is arranged in the mounting hole.

[0017] Preferably, the motor drives the sleeve to rotate, and the friction between the sleeve and the rotating shaft drives the rotating worktable to rotate. When the slide bar contacts the baffle, slippage occurs between the rotating shaft and the sleeve. As the products in the bin body gradually decrease, the slide bar moves upward under the action of the spring. When all the products are taken out, the bottom end of the slide bar passes the top of the baffle, and the motor drives the sleeve to drive the rotating shaft and the rotating worktable to rotate together. The rotating worktable rotates 180 degrees, so that the next magazine-type bin enters the loading position.

[0018] Preferably, the spring progress coefficient of the aerogel loading workbench is equal to the ratio of the weight to the thickness of the aerogel, and the spring progress coefficient of the silicone frame loading workbench is equal to the ratio of the weight to the thickness of the silicone frame, ensuring that the top layer of aerogel and the silicone frame are on the same horizontal line.

[0019] Preferably, a receiving groove is provided at the bottom center of the base, the motor is fixed in the receiving groove by screws, and the output shaft of the motor is rotatably connected to the base by a bearing, which facilitates the installation and removal of the motor.

[0020] Preferably, the side walls of the silo are symmetrically provided with notches to facilitate adding products into the silo.

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0036] Please refer to Figures 1 to 7 A dual-group aerogel and silicone frame circulating feeding device mainly includes an aerogel feeding worktable 1 and a silicone frame feeding worktable 2, with a pressing worktable located between them. The pressing worktable is equipped with X and Z axis drive modules, and the output ends of these drive modules are equipped with pneumatic suction cups for accurately sucking the aerogel and silicone frame. Each feeding worktable, whether aerogel feeding worktable 1 or silicone frame feeding worktable 2, adopts the following design structure:

[0037] First, there's a sturdy base 3, within which an electric motor 4 is firmly embedded and secured. The motor's output shaft passes directly through the top of the base 3 and connects to the transmission mechanism above. Next, there's a sleeve 5, tightly connected to the motor's output shaft. The top of the sleeve 5 features a specially designed mounting slot 6 for a rotating shaft 7. The top of this shaft 7 is fixedly connected to a rotating table 8, which serves as the primary material loading platform.

[0038] On the top of the rotating workbench 8, several clip-type silos 9 are symmetrically installed for storing aerogels or silica gel frames. Each clip-type silo 9 includes a silo body 10, inside which is disposed a freely sliding push plate 11. The bottom of the push plate 11 is fixedly connected to a slide rod 12, which passes through the bottom of the rotating workbench 8 and is slidably connected thereto. The outside of the slide rod 12 is wrapped with a spring 13, and the two ends of the spring 13 are respectively in contact with the rotating workbench 8 and the push plate 11 to provide thrust. At the top of the base 3, a baffle 14 is provided, which works in conjunction with the slide rod 12 to play a positioning role.

[0039] To ensure that the rotary table 8 can only rotate in one direction, a limiting device 15 is provided. This device consists of a one-way bearing 16 and a retaining ring 17. The inner ring of the one-way bearing 16 is tightly connected to the side wall of the rotary table 8, while the outer ring is connected to the retaining ring 17. Two connecting rods 18 are symmetrically connected to the bottom of the retaining ring 17. These two connecting rods 18 slide within mounting holes 19 in the base 3, further ensuring the stability of the device.

[0040] During operation, the motor 4 drives the sleeve 5 to rotate, and through friction, the shaft 7 and the rotary table 8 rotate together. When the slide bar 12 contacts the baffle 14, the slide bar 12 will be blocked, causing slippage between the shaft 7 and the sleeve 5. At this time, the rotary table 8 will temporarily stop rotating. As the products in the bin body 10 are gradually taken out, the spring 13 gradually releases energy under pressure, pushing the slide bar 12 to move upward. When all the products in the bin body 10 are taken out, the bottom end of the slide bar 12 will pass over the top of the baffle 14, and the slide bar 12 will be freed from the restraint. At this time, the motor 4 can drive the sleeve 5 and the shaft 7 to rotate again, causing the rotary table 8 to rotate 180 degrees, and bring the next magazine-type bin 9 into the loading position.

[0041] It should be emphasized that the output shaft of the motor 4 is always in a rotating state. When the products in the hopper body 10 are taken out, the automatic switching of the clip-type hopper 9 can be realized. The power of the motor 4 is relatively large, and the friction between the rotating shaft 7 and the sleeve 5 is not particularly large, so the motor 4 will not be overloaded and burned.

[0042] It's worth noting that to ensure the top layer of aerogel and the silicone frame are aligned, the spring rate coefficients of the aerogel loading platform 1 and the silicone frame loading platform 2 have been precisely calculated to be equal to the ratio of their respective material weight to thickness. Furthermore, a receiving slot 20 is provided at the bottom center of the base 3, through which the motor 4 passes and is secured with screws. A bearing is also installed between the output shaft of the motor 4 and the base 3 to facilitate installation and removal of the motor 4.

[0043] To facilitate product addition, the sidewalls of the hopper body 10 are provided with notches 22, while the sidewalls of the push plate 11 are provided with stoppers 23. These stoppers 23 slide within the notches 22, ensuring smooth up and down movement of the push plate 11. Furthermore, a chamfer 24 is provided at the entrance of the hopper body 10 to facilitate product insertion.

[0044] In this way, when the aerogel and silicone frame are stacked and placed in the warehouse 10 of the aerogel loading workbench 1 and the silicone frame loading workbench 2 respectively, the aerogel and silicone frame on the top layer can naturally be on the same horizontal line, providing a strong guarantee for subsequent precise loading operations.

[0045] It should be emphasized that after the aerogel and silicone frames are stacked, the thickness variation range is relatively small.

[0046] How it works

[0047] Initial state:

[0048] The motor 4 is in a continuous rotation state, but its output shaft transmits power through the friction between the sleeve 5 and the rotating shaft 7.

[0049] The clip-type hopper 9 on the rotating workbench 8 is filled with aerogel or silica gel frame, and the slide bar 12 is kept in contact with the baffle 14 under the action of the spring 13, limiting the further rotation of the rotating workbench 8.

[0050] Loading process:

[0051] When loading is required, the X and Z axis drive modules are started, driving the pneumatic suction cup to move above the clip-type hopper 9 located at the loading position.

[0052] The pneumatic suction cup picks up the top layer of aerogel or silicone frame and moves it to the pressing table for the next step.

[0053] As the material decreases, the spring 13 gradually releases energy, pushing the slide bar 12 to move upward.

[0054] Silo switching:

[0055] When the bottom end of the slide bar 12 passes over the top of the baffle 14, the slide bar 12 is no longer blocked. At this time, the motor 4 can drive the sleeve 5 and the rotating shaft 7 to continue rotating, so the rotating workbench 8 will rotate 180 degrees to rotate another clip-type hopper 9 to the loading position. After taking out the product, the clip-type hopper 9 is reloaded with the product, causing the slide bar 12 to move down again, thereby achieving the blockage with the baffle 14.

[0056] Due to the limiting effect of the one-way bearing 16 , the rotary table 8 can only rotate in one direction.

[0057] Repeat the operation:

[0058] The above process is repeated continuously to achieve continuous loading of aerogel and silicone frame.

[0059] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
