Description

Technical Field

[0001] This invention relates to the technical field of thermal insulation component assembly and packaging, specifically to a fully automated assembly and packaging equipment for thermal insulation and protection components. Background Technology

[0002] With the development of the new energy industry, the demand for thermal insulation components has increased. Manufacturers need to improve production efficiency and ensure quality. Currently, thermal insulation components generally use PET film to encapsulate aerogel felt in a silicone frame, using the thermal insulation and flame retardant functions of aerogel to protect the safety of batteries or cells.

[0003] In the current production system, the efficiency of manually stacking PET films and filling aerogel felt is too low, making it difficult to improve production efficiency. Furthermore, manual stacking also makes it difficult to effectively control the quality of the assembled thermal insulation components. Summary of the Invention

[0008] The encapsulation film and assembly mechanism can transform the encapsulation film from a planar conveying state to a U-shaped state. In the U-shaped state, the encapsulation film can be horizontally placed into a silicone frame with felt material at the U-shaped opening, so that the encapsulation film covers the upper and lower surfaces of the silicone frame with felt material.

[0009] After the thermo-press sealing is completed, the sealing film can be restored to a planar state.

[0010] Optionally, the assembly mechanism includes a bracket fixed to the hot press body, two sets of roller frames are installed on the top of the bracket, an assembly roller is rotatably installed between each set of roller frames, an assembly gap is left between the two assembly rollers, and the encapsulation film is attached to the outer wall of the two assembly rollers and kept horizontal.

[0011] The assembly mechanism also includes a transfer component, which controls the silicone frame with felt material to pass through the assembly gap and transforms the encapsulation film into a U-shaped state.

[0012] In the U-shaped position, the transfer component can displace the silicone frame with felt material to directly below the hot pressing station of the hot press body.

[0013] Optionally, the transfer assembly includes a driver and a fixture, the driver controlling the horizontal movement of the fixture and allowing it to extend into the assembly gap, the fixture having a through-hole bearing cavity that forms an interference fit with the frame wall of the felt silicone frame.

[0014] Optionally, the fixture has assembly slots at both the top and bottom, forming a stepped structure between the two assembly slots and the top or bottom of the fixture. The encapsulation film can cover the upper and lower surfaces of the silicone frame with felt material, and the encapsulation film will cover the outer wall of the fixture around the assembly slots, completely sealing the opening of the assembly slots. The fixture also has suction slots at both the top and bottom, which are interconnected with the assembly slots. During hot-press encapsulation, the suction slots can communicate with the vacuum hot-press cover.

[0015] Optionally, the encapsulation film includes a release liner and multiple PET layers, the multiple PET layers being intermittently distributed on the release liner, and a filler layer being distributed between any two adjacent PET layers. The filler layer can fill the missing thickness of the release liner, and the length of the filler layer is sufficient to allow two adjacent PET layers to completely cover the outer wall of the fixture surrounding the assembly slot.

[0016] Optionally, the encapsulation film is designed with multiple rows of verification groups. Each verification group includes multiple first signal holes opened on the filler layer and release liner. The arrangement direction of the first signal holes is perpendicular to the running direction V of the encapsulation film. The end of the fixture that abuts against the encapsulation film is provided with multiple second signal holes. Each of the multiple second signal holes corresponds one-to-one with the first signal holes. A laser emitter is installed inside each of the second signal holes. A laser receiver is fixedly installed on the top of the bracket. The laser receiver can receive the verification light emitted from the second signal holes. When the encapsulation film is in a U-shaped state, when the two PET layers completely cover the outer wall of the fixture around the assembly groove, and the two PET layers are symmetrical vertically, the first signal holes can communicate with the second signal holes.

[0017] Optionally, the internal space of the vacuum hot press cover can completely cover the periphery of the assembly slot, and the outer frame of the vacuum hot press cover is smaller than the top and bottom planes of the fixture.

[0018] Optionally, the contact end between the fixture and the encapsulation film is designed with rounded corners, and the contact end of the fixture is provided with a smooth surface.

[0020] Optionally, the end of the vacuum heat press cover is provided with a groove for fitting the encapsulation film, and a sealing gasket is fixedly installed in the groove.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. By utilizing the state transition of the encapsulation film, the assembly of the silicone frame with felt and the encapsulation film can be carried out quickly.

[0023] Second, by utilizing the U-shaped encapsulation film, the preheating and pressing process of the silicone frame can be reduced, simplifying the process flow and accelerating production efficiency.

[0024] Third, the hot pressing between the encapsulation film and the silicone frame makes the hot pressing quality between the PET layer and the silicone frame superior in applications that need to withstand higher temperatures. In addition, the mechanical strength of the silicone frame is usually higher than that of the PET film. This makes the hot pressing quality between the encapsulation film and the silicone frame provide higher strength and stability to the thermal insulation component. Attached Figure Description

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1 to 10 This invention provides a technical solution: a fully automated assembly and packaging equipment for thermal insulation and protection components, comprising:

[0038] The hot press body 1 and its two vacuum hot press covers 3 at the output end can hot press the assembled packaged object; the packaged film and the assembly mechanism can transform the packaged film from a planar conveying state to a U-shaped state. In the U-shaped state, the U-shaped opening of the packaged film can be horizontally placed into the silicone frame 19 with felt material, so that the packaged film covers the upper and lower surfaces of the silicone frame 19 with felt material.

[0039] After thermo-press sealing is completed, the sealing film can be restored to a planar state.

[0040] In this invention, the silicone frame 19 with felt material needs to be assembled first. The aerogel felt can be interference-sealed into the silicone frame by means of needle punching or transfer. Then, the encapsulation film needs to be assembled into the assembly mechanism. At this time, the assembly mechanism works and can transform the encapsulation film in the planar conveying state into a U-shaped state, that is, the silicone frame 19 with felt material can enter into the U-shape, so that the surface of the encapsulation film can contact the upper and lower surfaces of the silicone frame 19 with felt material to complete the assembly. At this time, the hot press body 1 can be used to hot press the assembled encapsulation object to complete the encapsulation.

[0041] In the above process, by resetting the state of the encapsulation film after each encapsulation is completed, automatic and rapid assembly can be performed, thereby improving assembly speed and production efficiency.

[0042] In a preferred embodiment, the assembly mechanism includes a bracket 2 fixed to the hot press body 1. Two sets of roller frames 7 are mounted on the top of the bracket 2, with an assembly roller 6 rotatably mounted between each set of roller frames 7. An assembly gap is left between the two assembly rollers 6. The encapsulation film is adhered to the outer walls of the two assembly rollers 6 and remains horizontal. The assembly mechanism also includes a transfer component, which controls the silicone frame 19 with felt material to pass through the assembly gap and transforms the encapsulation film into a U-shape. In the U-shape state, the transfer component can displace the silicone frame 19 with felt material to directly below the hot pressing station of the hot press body 1. Please refer to [link to previous section]. Figures 2 to 10 In this embodiment, the two assembly rollers 6 work together to restrict the encapsulation film and keep it in a planar conveying state. The two ends of the encapsulation film are respectively connected to the material pulling device and the electric unwinder, and both are controlled by the tension system to effectively control the operation of the encapsulation film. The assembly gap formed between the two assembly rollers 6 can provide space or path for the silicone frame 19 with felt material to enter. When in the U-shaped state, the encapsulation film and the silicone frame 19 with felt material can be under the hot pressing position of the hot press body 1. After the encapsulation film and the silicone frame 19 with felt material are assembled, they can be directly encapsulated, improving assembly efficiency and encapsulation efficiency.

[0043] In detail, in the existing technology, when encapsulating the heat insulation component, it is necessary to first unwind and pull two PET films, then preheat and press the silicone frame with the lower PET film so that the lower PET film can support the silicone frame, then transfer the aerogel felt to the silicone frame, and then heat press the upper and lower PET films together. The process is too complicated and affects the heat pressing efficiency. In this embodiment, a single PET film is used directly, and the heat pressing of the PET film and the silicone frame is directly utilized, which improves efficiency and quality.

[0044] Based on the assembly mechanism embodiment, the transfer assembly includes a driver and a fixture 4. The driver controls the horizontal movement of the fixture 4 and allows it to extend into the assembly gap. The fixture 4 has a through-hole bearing cavity that forms an interference fit with the frame wall of the felt-covered silicone frame 19. For details, please refer to [link to relevant documentation]. Figure 4 and Figure 5 In this embodiment, by designing a driver and a fixture 4, the fixture 4 can carry and transport the silicone frame through the carrying cavity, which is more efficient than the PET film used to carry the silicone frame and has stronger stability than the prior art. Furthermore, by designing an interference fit, there is no need to use materials such as glue to ensure the stability between the aerogel felt and the silicone frame.

[0045] Based on the transfer component embodiment, the top and bottom of the fixture 4 are provided with assembly grooves 8, and the two assembly grooves 8 form a stepped structure with the top or bottom of the fixture 4. The encapsulation film can cover the upper and lower surfaces of the silicone frame 19 with felt material, and the encapsulation film will cover the outer wall of the fixture 4 around the assembly grooves 8, completely sealing the opening of the assembly grooves 8. The top or bottom of the fixture 4 is provided with suction grooves 12, and the suction grooves 12 are interconnected with the assembly grooves 8. During hot pressing encapsulation, the suction grooves 12 can communicate with the vacuum hot pressing cover 3.

[0046] Please refer to the following: Figures 4 to 10 Please refer to details Figure 8 The enlarged view shows that, in this embodiment, due to the design of the encapsulation film, the encapsulation film can cover the top of the assembly groove 8. This allows the vacuum heat press cover 3 to be connected to the suction groove 12 during the vacuuming process, so that the vacuum heat press cover 3 can use the suction groove 12 to extract the air between the silicone frame and the PET film. This makes the adhesion between the encapsulation film and the silicone frame tighter and also improves the heat pressing quality between the silicone frame and the PET film.

[0047] Furthermore, the encapsulation film includes a release liner 5 and multiple PET layers 9. The multiple PET layers 9 are intermittently distributed on the release liner 5. A filler layer 11 is distributed between any two adjacent PET layers 9. The filler layer 11 can fill the missing thickness of the release liner 5. The length of the filler layer 11 is sufficient to allow two adjacent PET layers 9 to completely cover the outer wall of the fixture 4 surrounding the assembly groove 8. For details, please refer to [link to relevant documentation]. Figure 7 As shown in the enlarged view, in this embodiment, the filler layer 11 can keep the thickness of the entire encapsulation film consistent, and the filler layer 11 can reduce the amount of encapsulation film used. Secondly, the PET layer 9 can completely cover the outside of the assembly groove 8, thereby improving the bonding quality between the PET layer 9 and the silicone frame and the vacuuming quality.

[0048] In detail, in existing technologies, the encapsulation of thermal insulation cotton is generally achieved by heat-pressing the upper and lower PET films together. Although the silicone frame and the PET film can be tightly bonded after vacuuming, the PET film may deform or detach from the silicone frame under the influence of external stress or tensile force. In this invention, the encapsulation film is directly heat-pressed to the silicone frame, which is simple and efficient, reduces the amount of excess PET film bonding and heat pressing, increases production and reduces the use of PET film raw materials. Moreover, the temperature resistance of the silicone frame is higher than that of the PET film, which makes the heat-pressing quality between the PET film and the silicone frame superior in applications that need to withstand higher temperatures. In addition, the mechanical strength of the silicone frame is usually higher than that of the PET film, which makes the heat-pressing quality between the PET film and the silicone frame provide higher strength and stability to the thermal insulation component.

[0049] Furthermore, the encapsulation film is designed with multiple rows of verification groups. Each verification group includes multiple first signal holes 13 opened on the filler layer 11 and the release liner 5. The arrangement direction of the first signal holes 13 is perpendicular to the running direction V of the encapsulation film. Multiple second signal holes 14 are opened at the end of the fixture 4 that abuts against the encapsulation film. Each second signal hole 14 corresponds to a first signal hole 13. A laser emitter 15 is installed inside each second signal hole 14. A laser receiver 16 is fixedly installed on the top of the bracket 2. The laser receiver 16 can receive the verification light emitted from the second signal holes 14. When the encapsulation film is in a U-shaped state, when the two PET layers 9 completely cover the outer wall of the fixture 4 around the assembly groove 8 and the two PET layers 9 are symmetrical, the first signal holes 13 can communicate with the second signal holes 14.

[0050] Please refer to the following: Figure 4 , Figure 5 and Figure 10 In this embodiment, in order to more accurately adhere the PET layer 9 to the top and bottom of the silicone frame 19 with felt material, it is necessary to detect each hot-pressed PET layer 9 in real time. In this embodiment, the first signal hole 13 and the second signal hole 14 are designed on the encapsulation film and the fixture 4, respectively. When the first signal hole 13 on the encapsulation film can be connected to the second signal hole 14, the verification light emitted by the laser emitter 15 can pass through the first signal hole 13 and the second signal hole 14 and be received by the laser receiver 16, so as to determine that the PET layer 9 is in the correct hot-pressing position. In addition, by designing the arrangement direction of multiple first signal holes 13, it is possible to detect whether the PET layer 9 has shifted during the process of being transported by the assembly roller 6. If a shift occurs, multiple first signal holes 13 and second signal holes 14 will not be fully connected, and only part of the verification light signal can be detected. If the PET layer 9 has not shifted, but only the transportation is inaccurate, the verification light emitted by the laser emitter 15 will be blocked by the filler layer 11, and the position of the PET layer 9 can be adjusted by the material pulling assembly.

[0051] Furthermore, the internal space of the vacuum hot press cover 3 can completely cover the periphery of the assembly groove 8, and the outer frame of the vacuum hot press cover 3 is smaller than the top and bottom planes of the fixture 4, so that the vacuum hot press cover 3 can completely cover the encapsulation film to be hot-pressed, and can form a cavity between the encapsulation film and the fixture 4 to facilitate vacuuming.

[0052] Furthermore, the contact end between the fixture 4 and the encapsulation film is designed with rounded corners, and the contact end of the fixture 4 is set with a smooth surface, which can reduce damage to the filler layer 11 or the PET layer 9 and improve the smooth transport performance of the encapsulation film.

[0053] Based on the transfer component embodiment, the driver includes an electric slider fixedly mounted on the side wall of the fixture 4, a guide rail 17 mounted on the top of the bracket 2, and a groove provided on the guide rail 17. The electric slider is controllably slidably mounted inside the groove. The electrically controlled electric slider can better control the running speed of the fixture 4, adjust the hot pressing position, and ensure that the assembled packaged object can accurately dock with the hot pressing station or vacuum hot pressing cover 3.

[0054] Furthermore, the end of the vacuum heat press cover 3 is provided with a groove for fitting the sealing film, and a sealing gasket 18 is fixedly installed in the groove. By installing the sealing gasket 18, the sealing capability of the vacuum heat press cover 3 can be improved.

[0055] The combination of the above structures simplifies the assembly and packaging efficiency of the heat insulation sheet, simplifies the packaging process, and saves on PET film consumption.

[0056] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the specification and drawings can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
