Description

Technical Field

[0001] The present application relates to the technical field of protective structures for assembly, and in particular to an assembly protective structure and an assembly jig. Background Art

[0002] The housing of electronic products can be constructed using a hybrid material combination of aluminum foil bonded to a plastic frame. This structure not only enhances the product's metallic appearance but also reduces costs. However, since aluminum is relatively soft, even after anodizing, its surface hardness is still insufficient. This can easily lead to localized collisions between the aluminum foil and the frame during assembly, resulting in an undesirable appearance.

[0003] To address the above issues, manual application of protective film can be used to reduce the phenomenon of positive breakage. Specifically, protective film is applied to the edges (bonding positions) of the aluminum sheet and the plastic frame to reduce the chance of positive breakage caused by collision. However, in this method, in order to improve the protection effect, a large number of protective films need to be manually applied. Moreover, they need to be removed immediately after assembly to avoid the protective film being unable to be removed after the screws are tightened. Therefore, manually applying protective film will increase material and labor costs. Summary of the Invention

DETAILED DESCRIPTION

[0031] In order to make the purpose, features, and advantages of this application more obvious and easy to understand, 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 only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

[0032] An embodiment of the present application provides an assembled protective structure, including a protective film, a moving component and a pneumatic limit component. The cooperation between the components can realize the automatic extension or retraction of the protective film. Particularly, during the movement of the protective film, the pneumatic limit component can be used to realize the unfolded state of the protective film without generating fluctuations, thereby ensuring that the protective film can move normally.

[0033] The following describes in detail the components of the assembled protective structure provided by the embodiment of the present application, as well as the positional relationship and connection relationship of the components, in conjunction with the accompanying drawings.

[0034] like Figure 1 and Figure 2 As shown, in the embodiment of the present application, the protective film 11 is arranged on the moving component 12, and the moving component 12 is used to drive the protective film 11 close to or away from the structure to be assembled 20; the pneumatic limit component 13 is arranged on the moving component 12, and the pneumatic limit component 13 is used to blow air flow toward the protective film 11 to make the protective film 11 in an unfolded state.

[0035] When the protective film 11 is used, it needs to be laid on the assembly position of the structure 20 to be assembled, such as on the edge of the shell buckle. The protective film 11 needs to be made of soft material, which does not affect the normal assembly operation while playing a protective role. After the assembly is completed, the protective film 11 needs to have a certain strength so that it can be pulled out smoothly.

[0036] The soft protective film 11 needs to be in an unfolded state when it is laid so that it can be smoothly moved to the position of the structure to be assembled 20. In the embodiment of the present application, the protective film 11 is blown with air by the pneumatic limit assembly 13 to keep the protective film 11 unfolded. The cooperation between the pneumatic limit assembly 13 and the protective film 11 will be described later.

[0037] For example, the protective film 11 includes a polyvinyl chloride plastic protective film 11 (PVC film), and the thickness of the protective film 11 ranges from 0.1 mm to 0.15 mm. For example, a 0.1 mm protective film 11 has certain toughness and strength to meet the requirements of repeated withdrawal operations.

[0038] like Figure 3 and Figure 4 As shown, in the embodiment of the present application, a length adjustment assembly 14 is provided at one end of the protective film 11; the length adjustment assembly 14 is used to adjust the length of the protective film 11 extending into the structure to be assembled 20. When the protective film 11 is used in different usage scenarios, the length of the protective film 11 extending into the structure to be assembled 20 varies. The length adjustment assembly 14 is used to adjust the length of the protective film 11 to improve the versatility of the assembled protective structure 10.

[0039] For example, the length adjustment component 14 includes a rotating shaft 141, an axle seat 142 and a fastening screw 143; one end of the protective film 11 is connected to the rotating shaft 141, and the protective film 11 is wound on the rotating shaft 141, and the axle seat 142 is provided with an axle hole, and the two ends of the rotating shaft 141 are respectively connected to the axle holes of the axle seat 142 on the same side, and the axle seat 142 is connected to the moving component 12; the axle seat 142 is provided with a screw hole passing through the axle hole, and the fastening screw 143 is threadedly connected to the screw hole, and by tightening the fastening screw 143, the end of the fastening screw 143 is tightened against the end of the rotating shaft 141.

[0040] The protective film 11 is wound around the rotating shaft 141 a certain number of times, and the unwound portion has a certain length. This portion of the protective film 11 is used to attach to the structure to be assembled 20. During normal use, the fastening screw 143 is tightened and presses against the rotating shaft 141, and the rotating shaft 141 cannot rotate. When the length of the protective film 11 needs to be adjusted, the fastening screw 143 is loosened, and the rotating shaft 141 can rotate. The rotating shaft 141 is rotated to adjust the length of the protective film 11. After the length is determined, the fastening screw 143 is tightened against the rotating shaft 141 again.

[0041] After the length of the protective film 11 is adjustable, the assembled protective structure 10 has higher versatility and is suitable for the assembly protection operations of different models of structures 20 to be assembled, thereby reducing the cost of using the equipment; in addition, when the protective film 11 needs to be replaced, such as after long-term use, the protective film 11 at the front end is worn out. Since a certain length of protective film 11 is wound on the rotating shaft 141, the protective film 11 that needs to be replaced can be cut off to complete the replacement. This replacement method is simple and quick.

[0042] like Figure 5 As shown, in the embodiment of the present application, the moving component 12 includes a driving device 121, a slide rail 122 and a slider 123; the slider 123 is slidingly connected to the slide rail 122, the pneumatic limit component 13 and the shaft seat 142 are arranged on the slider 123, and the driving device 121 is connected to the slider 123 or the pneumatic limit component 13, and is used to drive the slider 123 to slide on the slide rail 122.

[0043] For example, the driving device 121 includes a telescopic cylinder, the moving component 12 includes two parallel slide rails 122, and a slider 123 is provided on each slide rail 122. The driving device 121 is located between the two slide rails 122. The telescopic direction of the driving device 121 is set toward the structure to be assembled 20. When the driving device 121 is extended, the protective film 11 can be placed on the structure to be assembled 20. When the driving device 121 is retracted, the protective film 11 can be retracted.

[0044] like Figures 6 to 9 As shown, in the embodiment of the present application, the pneumatic limiting assembly 13 includes a first airflow generating device 131, a second airflow generating device 132 and a limiting device 133; the first airflow generating device 131 and the second airflow generating device 132 respectively blow air toward the protective film 11 to form an airflow, and the airflow adjusts the unfolding state of the protective film 11.

[0045] In the embodiment of the present application, the first airflow generating device 131 is provided on the slider 123 and is located below the protective film 11. The first airflow generating device 131 is used to blow a first airflow toward the structure to be assembled 20. The protective film 11 located above the first airflow is in an unfolded state under the action of the first airflow.

[0046] At the end position of the protective film 11, a second airflow generating device 132 is set near the position of the structure to be assembled 20. The second airflow generating device 132 is set on the slide rail 122 and is located below the protective film 11. The second airflow generating device 132 is used to blow out a second airflow toward the protective film 11. The second airflow is perpendicular to the flow direction of the first airflow; before the protective film 11 moves to the structure to be assembled 20, the second airflow further adjusts the position of the protective film 11 to ensure that the protective film 11 can be moved to the position where the structure to be assembled 20 needs to be attached.

[0047] For example, the first airflow generating device 131 and the second airflow generating device 132 include an air pipe 134 and an air nozzle 135; multiple air nozzles 135 are evenly arranged along the length direction of the air pipe 134, the air nozzle 135 is connected to the air pipe 134, and the end of the air pipe 134 is used to connect to the gas generating device.

[0048] The plurality of air nozzles 135 are arranged side by side to blow out airflow synchronously. The airflow has a certain directionality. By utilizing this feature, the unfolding state of the protective film 11 can be adjusted.

[0049] In the embodiment of the present application, the protective film 11 may still be unstable under the influence of the first and second airflows. For example, the protective film 11 may vibrate in a wave-like manner, meaning that the protective film 11 is not in an ideal horizontal position. Therefore, a stopper 133 may be provided above the protective film 11. The stopper 133 is located on the side of the protective film 11 away from the second airflow generating device 132, and both ends of the stopper 133 are connected to the slide rail 122.

[0050] For example, the limiting device 133 has a limiting plane. If the limiting device 133 is plate-shaped, one side of the limiting plane is close to the protective film 11 and cooperates with the first airflow generating device 131 and the second airflow generating device 132 to prevent the protective film 11 from generating wave-like vibrations.

[0051] For example, the first airflow generating device 131 and the second airflow generating device 132 also include an airflow guide tube 136. The airflow guide tube 136 is located in the airflow path of the first or second airflow and is used to direct the first or second airflow to a designated area. The airflow guide tube 136 guides the first or second airflow, making the airflow more directional and directing it to a designated area, further ensuring the effect on the protective film 11. For example, the airflow guide tube 136 directs the first airflow toward the front end of the protective film 11, cooperating with the second airflow to position the protective film 11 in the desired unfolded state.

[0052] like Figure 10 As shown, an embodiment of the present application provides an assembly jig including the aforementioned assembly protection structure 10. The jig includes a body, with an assembly position 30 disposed on top of the body; the assembly position 30 is used to support the structure to be assembled 20, and an assembly protection structure 10 is disposed on each side of the assembly position 30 and each side of the structure to be assembled 20.

[0053] Taking the shell assembly of a laptop computer as an example, the assembly position 30 is rectangular, and assembly sliders 123 are provided around the assembly position 30 to fix the product to be assembled on the assembly position 30 using the assembly sliders 123 .

[0054] An assembly protection structure 10 is set at each side position. After the product to be assembled (laptop computer) is fixed at the assembly position 30, each assembly protection structure 10 drives the protective film 11 toward the product to be assembled, and the horizontal protective film 11 is placed at the assembly position of the product to be assembled.

[0055] Then, the rear cover of the laptop is assembled. At this time, due to the presence of the protective film 11, the damage during the assembly process can be reduced, that is, the appearance damage of the laptop caused by the assembly operation can be reduced.

[0056] During the assembly process, the back cover of the laptop computer will be pressed on part of the protective film 11, that is, part of the protective film 11 is in the gap between the back cover and the laptop computer body. After the back cover is assembled, the assembled protective structure 10 moves away from the laptop computer. During the movement, the assembled protective structure 10 pulls the protective film 11, and the pulling force gradually increases with the operation of the moving component 12. Finally, the protective film 11 is pulled out of the laptop computer, realizing the separation of the assembled protective structure 10 and the structure to be assembled 20. The assembled protective structure 10 is reset to the starting position, ready for the next attachment operation.

[0057] The present application provides an assembly protection structure 10 and an assembly jig. When in use, the structure to be assembled 20 is protected by attaching a protective film 11. The protective film 11 is automatically extended and retracted. During the movement of the protective film 11, especially during the extension action, the pneumatic limit assembly 13 is used to keep the protective film 11 in the extended state, so that the protective film 11 can be moved into place in the correct shape. The technical solution of the present application uses an automated form to operate the protective film 11, which improves work efficiency and reduces assembly costs. In addition, the pneumatic limit assembly 13 can further improve the assembly success rate during automated operation.
